    The D/V Chikyu, a scientific drilling vessel, is equipped with industry-standard riser capabilities. Riser drilling technology enables remarkable drilling and downhole logging capabilities and provides unprecedented hole-stability, enabling the shipboard team to retrieve high-quality wire-line logging data as well as well-preserved core samples. The 11 March 2011 Tohoku Oki mega-earthquake and tsunami cost over 18,000 casualties in NE Japan. Chikyu, docked in the Port of Hachinohe, was damaged by the tsunami. By April 2012, the ship was back in operation; drilling the toe of the Japan Trench fault zone where topographic surveys suggested there was up to 50 m eastward motion, the largest earthquake rupture ever recorded. During Integrated Ocean Drilling Program (IODP) Expeditions 343 and 343 T, Chikyu drilled 850 m below sea floor (mbsf) in 6,900+ m water depth and recovered core samples of a highly brecciated shear zone composed of pelagic claystone. A subseafloor observatory looking for temperature signatures caused by the fault friction during the earthquake, was installed and later successfully recovered. The recovered temperature loggers recorded data from which the level of friction during the mega-earthquake slip could be determined. Following Exp. 343, Chikyu began IODP Exp. 337, a riser drilling expedition into the Shimokita coal beds off Hachinohe, to study the deep subsurface biosphere in sedimentary units including Paleogene-Neogene coal beds. New records in scientific ocean drilling were achieved in deepest penetration (drilling reached 2,466 mbsf) and sample recovery. Currently Chikyu is conducting deep riser drilling at the Nankai Trough in the final stage of the NanTroSEIZE campaign. During the years 2011 to 2013, including drilling in the Okinawa Hydrothermal System, Chikyu's operational and scientific achievements have demonstrated that the ship's capabilities are vital for opening new frontiers in earth and biological sciences.

  8. The Economics of an Investment in Kaizen

    Kaizen has been widely accepted as a continuous process improvement with the gradualist approach. This paper presents the research carried out to explore the pattern of an investment in Kaizen to enhance overall profit. System dynamics-based simulation has been employed with an optimization technique, a Steepest Ascent approach, to improve experimental variables e.g. the amount of spending on prevention and appraisal activities, the time and the amount to reduce the investment which results in maximum Net Present Value (NPV) of profit. The simulation model in this study is based on a Thai automobile manufacturer as a case study company. The result suggests that the investment in Kaizen should spend on activities to eliminate and detect all defects in the early phase and then reduce economically when the process is under controlled. It can be named as the `Hybrid quality improvement', which was proved in this study that it provides greater overall profit than the Stepwise Kaizen and the constant spending. This study also presents the behavior of quality costs and profit against time scale along the different patterns of the investment in Kaizen.

    Mud gas logging has been commonly used in oil industry and continental scientific drilling to detect mainly hydrocarbon gases from the reservoir formation. Quick analysis of the gas provides almost real-time information which is critical to evaluate the formation and, in particular, safety of drilling operation. Furthermore, mud gas monitoring complements the lack of core or fluid samples particularly in a deep hole, and strengthen interpretations of geophysical logs. In scientific ocean drilling, on the other hand, mud gas monitoring was unavailable in riserless drilling through the history of DSDP and ODP, until riser drilling was first carried out in 2009 by D/V Chikyu. In IODP Exp 319, GFZ installed the same system with that used in continental drilling aboard Chikyu. High methane concentrations are clearly correlated with increased wood content in the cuttings. The system installation was, however, temporary and gas separator was moved during the expedition for a technical reason. In 2011, new mud gas monitoring system was installed aboard Chikyu and was used for the first time in Exp 337. The gas separator was placed on a newly branched bypass mud flow line, and the gas sample was sent to analysis unit equipped with methane carbon isotope analyzer in addition to mass spectrometer and gas chromatograph. The data from the analytical instruments is converted to depth profiles by calculating the lag effects due to mud circulation. Exp 337 was carried out from July 26 to Sep 30, 2011, at offshore Shimokita peninsula, northeast Japan, targeting deep sub-seafloor biosphere in and around coal bed. Data from the hole C0020A, which was drilled to 2466 mbsf with riser drilling, provided insights into bio-geochemical process through the depth of the hole. In this presentation, we show the design of Chikyu's new mud gas monitoring system, with preliminary data from Exp 337.

    It is our objective to provide you with a step-by-step approach to conducting a kaizen blitz within two days and describe how to achieve dramatic performance improvement with employee buy-in through this process. Kaizen blitz has been used dozens of times by the authors, and in some instances the same area has been blitzed as many as four times, with significant improvements each and every time. Employees have even taken it on themselves to conduct informal blitzes as a continuing improvement effort after a formal blitz has been conducted in their area. Blitzes can succeed in a variety of environments. The morning after the employees of one company attended this presentation, they self initiated a mini-blitz and discovered opportunities for improvement that they enthusiastically presented to management.

  11. Affecting the value chain through supplier kaizen.

    Forman, C R; Vargas, D H

    1999-02-01

    In the aerospace industry, typically 60 percent of a product's cost and 70 percent of the lead time are due to purchased material. To affect price and customer responsiveness, improvement initiatives must be extended into the supply chain. Many companies have developed supply base management systems that include long-term agreements with suppliers, partnering with suppliers in risk taking and product design, information sharing, and quality and delivery rating systems. The premise is that suppliers are an extension of the factory. But to take full advantage of customer-supplier relationships, the suppliers must be "developed" in the same manner as a manufacturing unit. Supplier kaizen is a method of bringing suppliers to the same level of operations as the parent company, through training and improvement projects, to ensure superior performance and nurture the trust that is required for strong partnerships. This article describes Sikorsky Aircraft's use of kaizen to improve its supply base management.

  12. Kaizen: ergonomics approach to occupational health and safety.

    PubMed

    Kumashiro, Masaharu

    2011-12-01

    Kaizen (work improvement) is the forte of Japanese industry. Kaizen activities were born in the early 20th century under the name efficiency research. These activities were the beginning of industrial engineering (IE). Later on people began to rethink the single-minded devotion to improving productivity. Then the job re-design concept was developed. The main target of kaizen in the area of occupational health and safety in Japanese manufacturing is the improvement of inadequate working posture followed by the improvement of work for transporting and lifting heavy objects. Unfortunately, the kaizen activities undertaken by most Japanese companies are still focused on improving productivity and quality. The know-how for promoting kaizen activities that integrate the three aspects of IE, occupational health, and ergonomics is not being accumulated, however. In particular, the IE techniques should be incorporated into kaizen activities aimed at occupational safety and health, and the quantitative assessment of workload is required. In addition, it is important for on-the-job kaizen training in the ERGOMA Approach for production supervisors, who are the main advocates of IE kaizen.

  13. An Information Management System for CHIKYU Operation and its Future

    2005-12-01

    The CDEX (Center for Deep Earth Exploration, JAMSTEC) is an implementing organization of a riser drilling vessel, CHIKYU ("Earth"). CHIKYU has a large capability to produce a wide variety of data, core measurement data, logging data, mud logging data, cuttings data and monitoring data in boreholes, etc. Also CDEX conducts site survey for safety drilling and publication before and after cruises. It is critical that these diverse data be managed using a unified, coherent method, and that they be organized and provided to users in an intuitive, clearly understandable way that reflects the aims and underlying philosophies of the IODP and JAMSTEC. It is crucial that these data are accessible to users through an integrated interface in which all data formats, management tools, and procedures are standardized. Meeting these goals will assure total usability for scientists, administrators, and the public, from data creation to uploading and cataloging, to end use and publication. CDEX is developing an integrated information management system, call "SIO7" (Scientific Information from 7 Oceans) for CHIKYU operation, and would like to extend to adopt various information handling systems in geosciences. The SIO7 composed of 2 major systems, J-CORES (JAMSTEC Core Systematics) and DEXIS (Deep Earth Exploration Information System) (see http://sio7.jamstec.go.jp/ for the details). J-CORES is a database system designated to manage all aspects of core data. The system is modeled on the JANUS system developed by and for ODP, but implements an extended, somewhat modified data model. The functions that support onboard and real time data input operations have also been strengthened. A variety of data visualization and visual core description functions have been added, and data loading from those applications has been automated, making the system as a whole both powerful and easy to use. On the other hand, DEXIS is developed based on the combination and integration of existing off

    2009-12-01

    Recent position statements from health care organizations have placed a strong emphasis on continuous quality improvement (CQI). CQI finds many of its roots in kaizen, which emphasizes small, low-cost, low-risk improvements. Based on the successful Kaizen Programs at organizations such as Toyota, the authors thought the emergency department (ED) would be an ideal environment to benefit from such a program. The authors sought to create a CQI program using a suggestion-based model that did not require a large time commitment, was easy to implement, and had the potential to empower all physicians in the department. It would not take the place of other improvement efforts, but instead augment them. The hypothesis was that such a program would foster sustainable engagement of emergency physicians in system improvement efforts and lead to a continuous stream of low-cost implementable system improvement interventions. A CQI program was created for the physician staff of the Department of Emergency Medicine at Vanderbilt University Medical Center, focusing on a suggestion-based model using kaizen philosophy. Lectures teaching kaizen philosophy were presented. Over the past 4 years, a methodology was developed utilizing a Web-based application, the Kaizen Tracker, which aids in the submission and implementation of suggestions that are called kaizen initiatives (KIs). The characteristics of the KIs submitted, details regarding resident and faculty participation, and the effectiveness of the Kaizen Tracker were retrospectively reviewed. There were 169, 105, and 101 KIs placed in the postimplementation calendar years 2006, 2007, and 2008, respectively. Seventy-six percent of KIs submitted thus far have identified a "process problem." Fifty-three percent of KIs submitted have led to operational changes within the ED. Ninety-three percent of the resident physicians entered at least one KI, and 73% of these residents submitted more than one KI. Sixty-nine percent of the

    Objectives Kaizen, or continuous improvement, lies at the core of lean. Kaizen is implemented through practices that enable employees to propose ideas for improvement and solve problems. The aim of this study is to describe the types of issues and improvement suggestions that hospital employees feel empowered to address through kaizen practices in order to understand when and how kaizen is used in healthcare. Methods We analysed 186 structured kaizen documents containing improvement suggestions that were produced by 165 employees at a Swedish hospital. Directed content analysis was used to categorise the suggestions into following categories: type of situation (proactive or reactive) triggering an action; type of process addressed (technical/administrative, support and clinical); complexity level (simple or complex); and type of outcomes aimed for (operational or sociotechnical). Compliance to the kaizen template was calculated. Results 72% of the improvement suggestions were reactions to a perceived problem. Support, technical and administrative, and primary clinical processes were involved in 47%, 38% and 16% of the suggestions, respectively. The majority of the kaizen documents addressed simple situations and focused on operational outcomes. The degree of compliance to the kaizen template was high for several items concerning the identification of problems and the proposed solutions, and low for items related to the test and implementation of solutions. Conclusions There is a need to combine kaizen practices with improvement and innovation practices that help staff and managers to address complex issues, such as the improvement of clinical care processes. The limited focus on sociotechnical aspects and the partial compliance to kaizen templates may indicate a limited understanding of the entire kaizen process and of how it relates to the overall organisational goals. This in turn can hamper the sustainability of kaizen practices and results. PMID:27473953

    The Toyota Production System, also known as Lean, is a structured approach to continuous quality improvement that has been developed over the past 50 years to transform the automotive manufacturing process. In recent years, these techniques have been successfully applied to quality and safety improvement in the medical field. One of these techniques is kaizen, which is the Japanese word for "good change." The central tenant of kaizen is the quick analysis of the small, manageable components of a problem and the rapid implementation of a solution with ongoing, real-time reassessment. Kaizen adds an additional "human element" that all stakeholders, not just management, must be involved in such change. Because of the small size of the changes involved in a kaizen event and the inherent focus on human factors and change management, a kaizen event can serve as good introduction to continuous quality improvement for a radiology department.

    The purpose of this study was to calculate the cost savings associated with using the kaizen approach in our hospital. Originally developed in Japan, the kaizen approach, based on the idea of continuous improvement, has considerable support in North America, including in the Quebec health care system. This study assessed the first fifteen kaizen projects at the CHUS. Based on an economic evaluation, we showed that using the kaizen approach can result in substantial cost savings. The success of the kaizen approach requires compliance with specific prerequisites. The future of the approach will depend on our ability to comply with these prerequisites. More specifically, such compliance will determine whether the approach is merely a passing fad or a strategy for improving our management style to promote greater efficiency.

    2013-12-01

    Pressure coring is a technique to keep in-situ conditions in recovering sub-seafloor sediment samples, which are potentially rich in soluble or hydrated gas. In regular core sampling, gas fractions are easily lost through the changes in the pressure and temperature during core recovery, and it has significant impact on the chemical components of the sample. Rapid degassing may also cause critical damages of original structures. To study original characteristics of gaseous sub-seafloor sediment, a new Hybrid Pressure Coring System (Hybrid PCS) was developed for the D/V Chikyu operation by adapting some of the existing pressure sampling technologies. Hybrid PCS is composed of three main parts: top section for the wireline operation, middle section for the accumulator and pressure controlling system, and the bottom section for the autoclave chamber. The design concept is based on that of Pressure Core Sampler used in Ocean Drilling Program, and of Pressure Temperature Core Sampler (PTCS) and Non-cooled PTCS of Japan Oil, Gas and Metals National Corporation (JOGMEC). Several modifications were made including that on the ball valve, which operates to close the autoclave after coring. The core samples are 51 mm in diameter and up to 3.5 m in length. The system is combined with the Extented Shoe Coring System on the Chikyu and best suited for coring of semi-consolidated formation up to about 3400 m from the sea level. Sample autoclave is compatible with Pressure Core Analysis and Transfer System (PCATS) of Geotek Ltd for sub-sampling and analysis under in-situ pressure. The analysis in PCATS includes X-ray CT scan and core logging with P-wave velocity and gamma density. Depressurization provides accurate volume of gas and its sub-sampling. Hybrid PCS was first tested during the Chikyu Exp. 906 at a submarine mud-volcano in the Nankai Trough. A 0.9 m of hydrate rich material was recovered from the summit (water depth: 2000 m) and the intact hydrate structure was observed

    Participatory intervention approaches that are embedded in existing organizational structures may improve the efficiency and effectiveness of organizational interventions, but concrete tools are lacking. In the present article, we use a realist evaluation approach to explore the role of kaizen, a lean tool for participatory continuous improvement, in improving employee well-being in two cluster-randomized, controlled participatory intervention studies. Case 1 is from the Danish Postal Service, where kaizen boards were used to implement action plans. The results of multi-group structural equation modeling showed that kaizen served as a mechanism that increased the level of awareness of and capacity to manage psychosocial issues, which, in turn, predicted increased job satisfaction and mental health. Case 2 is from a regional hospital in Sweden that integrated occupational health processes with a pre-existing kaizen system. Multi-group structural equation modeling revealed that, in the intervention group, kaizen work predicted better integration of organizational and employee objectives after 12 months, which, in turn, predicted increased job satisfaction and decreased discomfort at 24 months. The findings suggest that participatory and structured problem-solving approaches that are familiar and visual to employees can facilitate organizational interventions.

    In this paper, we introduce the new workflow line system consisted of the location and image recording, which led to the acquisition of workflow information and the analysis display. From the results of workflow line investigation, we considered the anticipated effects and the problems on KAIZEN. Workflow line information included the location information and action contents information. These technologies suggest the viewpoints to help improvement, for example, exclusion of useless movement, the redesign of layout and the review of work procedure. Manufacturing factory, it was clear that there was much movement from the standard operation place and accumulation residence time. The following was shown as a result of this investigation, to be concrete, the efficient layout was suggested by this system. In the case of the hospital, similarly, it is pointed out that the workflow has the problem of layout and setup operations based on the effective movement pattern of the experts. This system could adapt to routine work, including as well as non-routine work. By the development of this system which can fit and adapt to industrial diversification, more effective "visual management" (visualization of work) is expected in the future.

    Every customer preference is different but yet important. The global market is shifting rapidly, organizations are needed to continuously identify new opportunity to obtain competitive advantages. Literature suggested that manufacturing companies are needed to differentiate themselves through emphasize on quality and continuous improvement in product and services as a crucial part to secure and success in the future. The Total Quality Management (TQM) practices has developed a strong bearing on growth and competitiveness in market. Therefore, a proper continuous improvement (Kaizen) practice is needed to eliminate waste and value added in production to remain competitiveness and retained the potential customer. However, based on the previous study it had indicated an inconsistent result between TQM and BP. Besides that, researcher also less emphasized on mediator in previous work. Therefore, the purpose of this paper is to recommend the relationship between TQM and business performance with a mediator's effect of Kaizen. This proposed model attempt to create knowledge to both academician and company players to acquire a better understanding among the TQM and Kaizen practices. Consequently, the Structural Equation Modelling (SEM) techniques is applying to identify and evaluate the relationship among TQM, Kaizen, and business performance in developing a new TQM model.

    By means of introduction of the drilling vessel 'CHIKYU', riser drilling operations using mud fluid will be carried out in NanTroSEIZE Stage 2 for the first time as an oceanic scientific-drilling. For determining drilling operation parameter such as a mud density, a downhole experiment, leak-off test (LOT) or extended leak-off test (XLOT), is going to be implemented next to casing and cementing at each casing shoe during the drilling process. Data of the downhole experiment aimed for operation can also be used for an important scientific application to obtain in-situ stress information which is necessary for various cases of scientific drillings such as seismogenic zone drillings etc. In order to examine feasibility of the application of the LOT or XLOT data, we analyzed an example of XLOT conducted by the riser vessel CHIKYU during its Shimokita shakedown cruise, 2006; and then estimated magnitude of minimum principal stress in horizontal plane, Shmin. Moreover, we will propose the test procedures to possibly improve the quality of stress result from the applications of LOT or XLOT. The XLOT of Shimokita cruise was conducted under following conditions; 1180 m water depth, 525 mbsf (meter below seafloor) depth, 1030 kg/m3 fluid density (seawater) and 80 litter/min injection flow-rate. Estimated magnitude of the Shmin is equal to 18.3 MPa based on the assumption that fracture closure pressure balances with the minimum principal stress perpendicular to the fracture plane. For comparison, the vertical stress magnitude at the depth was estimated from density profile of core samples retrieved from the same borehole; and was equal to 20 MPa approximately. These two values can be considered to be not disagreement. Therefore, we can say that the XLOT data is valuable and practical for estimating the magnitude of minimum horizontal stress. From the viewpoint of determining stress magnitude, the XLOT is more essential rather than the LOT because it might be hardly to obtain

    Modern external beam radiation therapy treatment delivery processes potentially increase the number of tasks to be performed by therapists and thus opportunities for errors, yet the need to treat a large number of patients daily requires a balanced allocation of time per treatment slot. The goal of this work was to streamline the underlying workflow in such time-interval constrained processes to enhance both execution efficiency and active safety surveillance using a Kaizen approach. A Kaizen project was initiated by mapping the workflow within each treatment slot for 3 Varian TrueBeam linear accelerators. More than 90 steps were identified, and average execution times for each were measured. The time-consuming steps were stratified into a 2 × 2 matrix arranged by potential workflow improvement versus the level of corrective effort required. A work plan was created to launch initiatives with high potential for workflow improvement but modest effort to implement. Time spent on safety surveillance and average durations of treatment slots were used to assess corresponding workflow improvements. Three initiatives were implemented to mitigate unnecessary therapist motion, overprocessing of data, and wait time for data transfer defects, respectively. A fourth initiative was implemented to make the division of labor by treating therapists as well as peer review more explicit. The average duration of treatment slots reduced by 6.7% in the 9 months following implementation of the initiatives (P = .001). A reduction of 21% in duration of treatment slots was observed on 1 of the machines (P < .001). Time spent on safety reviews remained the same (20% of the allocated interval), but the peer review component increased. The Kaizen approach has the potential to improve operational efficiency and safety with quick turnaround in radiation therapy practice by addressing non-value-adding steps characteristic of individual department workflows. Higher effort opportunities are

    The majority of costs associated with esophagectomy are related to the initial 3 days of hospital stay requiring intensive care unit stays, ventilator support, and intraoperative time. Additional costs arise from hospital-based services. The major cost increases are related to complications associated with the procedure. We attempted to define these costs and identify expense management by streamlining care through strict adherence to patient care maps, operative standardization, and rapid discharge planning to reduce variability. Utilizing methods of Kaizen philosophy we evaluated all processes related to the entire experience of esophageal resection. This process has taken over 5 years to achieve, with quality and cost being tracked over this time period. Cost analysis included expenses related to intensive care unit, anesthesia, disposables, and hospital services. Quality improvement measures were related to intraoperative complications, in-hospital complications, and postoperative outcomes. The Institutional Review Board approved the use of anonymous data from standard clinical practice because no additional treatment was planned (observational study). Utilizing a continuous process improvement methodology, a 43% reduction in cost per case has been achieved with a significant increase in contribution margin for esophagectomy. The length of stay has been reduced from 14 days to 5. With intraoperative and postoperative standardization the leak rate has dropped from 12% to less than 3% to no leaks in our current Kaizen modification of care in our last 64 patients. Utilizing lean manufacturing techniques and continuous process evaluation we have attempted to eliminate variability, standardized the phases of care resulting in improved outcomes, decreased length of stay, and improved contribution margins. These Kaizen improvements require continuous interventions, strict adherence to care maps, and input from all levels for quality improvements. Copyright © 2011 The

    With increased international competitiveness in the automotive industry, came the concern of the companies save costs and lower production costs. For this purpose many ways are designed to reduce costs and waste of raw materials and reduce activities that do not aggregate value to manufacturing processes. In the early XVII appears the manufacturing system, which processes were hard with little concern for the health and safety of employees and conditions of the workplace. After the advent of the production system called lean manufacturing, a new paradigm in terms of production system capable of providing high levels of productivity and quality. It is based on waste elimination that occur during the production process. After began a new way of thinking, creating a culture of continuous improvement and lean process with no waste and reducing costs, without neglecting the welfare worker and improving the conditions of their work environment. This paper presents a reflection on the application of ergonomics in a lean production system of an automotive industry, using methodology based on the Kaizen (Continuous Improvement) to gain performance and improving the conditions of the workplace, also will be presented with positive and negative points in using this methodology in relation to ergonomics. The research will be conducted by collecting data 'in loco' and interviews with workers. Some studies show that in companies that are lean system and using the methodology of Kaizen, the results of product quality, levels of absenteeism and accidents are better than those obtained in companies that do not apply the same concept.

    The art of teaching freshmen students is undergoing a rapid paradigm change. Classical forms of teaching are not applicable any more and an unmanageable offer of new multimedia tools and concepts is glutting the market. Moreover, compared to previous courses, the class size triples. In view of these challenges, we implemented a new teaching concept best described as Kaizen learning. By Kaizen learning, we define a teaching philosophy that is based on a concise mix of short learning units (with feedback loops and tests) and of carefully chosen repetitions (also with feedback loops and tests) to calibrate a course for the students. Here, this intensive blended, student-centred learning paradigm is analysed together with its direct impact on the students' performance. This case study leads to easy-to-implement key drivers for successfully teaching science in Oman, such as (1) human-human interaction, (2) clearly communicated expectations, (3) avoidance of a short-term learning attitude, (4) a no-calculator policy, (5) continuous Kaizen learning, and (6) balanced combination of traditional teaching and e-learning.

    The middle Okinawa trough, along the Ryukyu-arc on the margin of the western Pacific, fosters several hydrothermal fields. The cruise CK16-01 of D/V CHIKYU targeted the Iheya-North Field and Noho hydrothermal site. More than ten-days extensive coring was carried out with Logging While Drilling (LWD) and deployment of Kuroko cultivation apparatus between February 29th to March 17th2016. Here we present the results of the physical property measurements obtained using Chikyu's on-board laboratory. Cores were sampled among three sites where the seafloor environments were quite different: the Noho site (C9017), a site between the Natsu and Aki sites of the Iheya-North field (C9021), and the Iheya-North Aki site (C9023). Site C9017 was near the center of the hydrothermal activity, and the obtained core was limited 36 m in length and 30 % in the recovery rate. At 70 mbsf (meters below seafloor), the grain density and bulk density of the sediment reached their maxim (3.7 g/m3 and 2.7 g/cm3, respectively), while thermal conductivity reached its lowest value (0.6 W/m·K). Site C9021 yielded a 54 m core, with a core recovery rate of 50 %. Coarse pumiceous layers were found at 68 mbsf, with a hydrothermally altered layer appearing below 68 mbsf. The mean grain density value was 2.4 g/cm3 and was uniform throughout the core. The mean bulk density value of the pumiceous layers was 1.3 g/cm3, and of the hydrothermally altered layer was 2.1 g/cm3. Site C9023 was close to the active hydrothermal chimneys of the Iheya-North Aki site, and yielded 33 m of core with a core recovery rate of 16 %. Massive sulfide layers were found below 48 mbsf with grain density and bulk density values varying between 2.8-4.7 g/cm3 and 1.5-3.9 g/cm3, respectively. Magnetic susceptibility exhibited a high anomaly in a sedimented anhydrite layer found between 95 and 135 mbsf, and a high porosity and low resistivity zone was found below 150 mbsf. Together, these data from drilling cores and onboard

    During the Integrated Ocean Drilling Program (IODP) Expedition 331 at the Iheya North hydrothermal system in the Mid-Okinawa Trough by the D/V Chikyu, we conducted microbiological contamination tests of the drilling and coring operations. The contamination from the drilling mud fluids was assessed using both perfluorocarbon tracers (PFT) and fluorescent microsphere beads. PFT infiltration was detected from the periphery of almost all whole round cores (WRCs). By contrast, fluorescent microspheres were not detected in hydrothermally active core samples, possibly due to thermal decomposition of the microspheres under high-temperature conditions. Microbial contamination from drilling mud fluids to the core interior subsamples was further characterized by molecular-based evaluation. The microbial 16S rRNA gene phylotype compositions in the drilling mud fluids were mainly composed of sequences of Beta- and Gammaproteobacteria, and Bacteroidetes and not archaeal sequences. The phylotypes that displayed more than 97% similarity to the sequences obtained from the drilling mud fluids were defined as possible contaminants in this study and were detected as minor components of the bacterial phylotype compositions in 13 of 37 core samples. The degree of microbiological contamination was consistent with that determined by the PFT and/or microsphere assessments. This study suggests a constructive approach for evaluation and eliminating microbial contamination during riser-less drilling and coring operations by the D/V Chikyu. PMID:24265628

    The Nankai-Trough Seismogenic Zone Experiment (NanTroSEIZE) has carried out several drilling expeditions in the Kumano Basin off the Kii-Peninsula of Japan with the deep-sea scientific drilling vessel Chikyu. Core sampling runs were carried out during the expeditions using an advanced multiple wireline coring system which can continuously core into sections of undersea formations. The core recovery rate with the Rotary Core Barrel (RCB) system was rather low as compared with other methods such as the Hydraulic Piston Coring System (HPCS) and Extended Shoe Coring System (ESCS). Drilling conditions such as hole collapse and sea conditions such as high ship-heave motions need to be analyzed along with differences in lithology, formation hardness, water depth and coring depth in order to develop coring tools, such as the core barrel or core bit, that will yield the highest core recovery and quality. The core bit is especially important in good recovery of high quality cores, however, the PDC cutters were severely damaged during the NanTroSEIZE Stages 1 & 2 expeditions due to severe drilling conditions. In the Stage 1 (riserless coring) the average core recovery was rather low at 38 % with the RCB and many difficulties such as borehole collapse, stick-slip and stuck pipe occurred, causing the damage of several of the PDC cutters. In Stage 2, a new design for the core bit was deployed and core recovery was improved at 67 % for the riserless system and 85 % with the riser. However, due to harsh drilling conditions, the PDC core bit and all of the PDC cutters were completely worn down. Another original core bit was also deployed, however, core recovery performance was low even for plate boundary core samples. This study aims to identify the influence of the RCB system specifically on the recovery rates at each of the holes drilled in the NanTroSEIZE coring expeditions. The drilling parameters such as weight-on-bit, torque, rotary speed and flow rate, etc., were analyzed

The mission was successfully completed as data from the test, and associated development activities were analyzed, transferred to stakeholders, and well documented. Positive lessons learned from Ares I-X were that the application of lean thinking principles and kaizen practices are effective in streamlining development activities. Ares I-X, like other historical rocket development projects, was hampered by technical, cost, and schedule challenges and if not addressed boldly could have resulted in cancellation of the test. The mission management team conducted nine major meetings, referred to as lean events, across its elements to assess plans, procedures, processes, requirements, controls, culture, organization, use of resources, and anything that could be changed to optimize schedule or reduce risk. The preeminent aspect of the lean events was the focus on value added activities and the removal or at least reduction in non-value activities. Trained Lean Six Sigma facilitators assisted the Ares I-X developers in conducting the lean events. They indirectly helped formulate the mission s own unique methodology for assessing schedule. A core team was selected to lead the events and report to the mission manager. Each activity leveraged specialized participants to analyze the subject matter and its related processes and then recommended alternatives and solutions. Stakeholders were the event champions. They empowered and encouraged the team to succeed. The keys to success were thorough preparation, honest dialog, small groups, adherence to the Ares I-X ground rules, and accountability through disciplined reporting and tracking of actions.

    In future IODP expeditions, a series of long-term borehole observatories that combine elements of CORKs (e.g., ODP Leg 196 in the Nankai Trough) and NEREID (ODP Leg 186 at Japan Trench), will be installed into the three holes along the NanTroSEIZE transect offshore the Kii Peninsula of southern Honshu, Japan (Sites C0002, C0009 and C0010). The three boreholes are located within and above regions of contrasting behavior of the megasplay fault zone and plate boundary (i.e., a site ~6-7 km above the “locked” seismogenic plate boundary [Site C0009], a site above the updip edge of the locked zone [Site C0002], and a shallow site in the megasplay fault zone and footwall where slip is presumed to be aseismic [Site C0010]). These observatories aim to monitor seismic activity, slow slip behavior, and possibly interseismic strain accumulation at the plate boundary and megasplay faults across a range of pressure, temperature, and kinematic conditions. Currently, the planned observation system for the boreholes consists of an array of sensors designed to monitor slow crustal deformation (e.g., strain, tilt, and pore pressure as a proxy for strain), seismic events including very low frequency earthquakes, hydrologic transients associated with strain events, ambient pore pressure, and temperature. In order to realize these long-term borehole observatories, one of the primary challenges is to install high- precision, sensitive sensors into the borehole without damaging them. In particular, strong vibration can damage sensors during the lowering on drill pipe through the water column, especially in areas of strong ocean currents such as the Nankai Trough. During IODP Expedition 319 from May - August 2009 , we conducted a simulation of the planned future borehole sensor installation at Site C0010 after casing operations, as part of the preparation for long-term borehole observatories in future NanTroSEIZE expeditions. This test had two main objectives: (1) to evaluate environmental conditions, such as shock, acceleration, and vibration during installation; and (2) to confirm sensor installation operational procedures, such as onboard assembly of the sensor tree, ship maneuvers to reenter the sensor tree, and entry into the hole. Acceleration and tilt data were recorded at 500 Hz and recovered after the dummy run test. Preliminary results from vibration analysis show that the strong vibration due to the high Kuroshio Current (~5 knot) occurred during the test. Spectral analysis of the collected acceleration data represents the drill pipe vibration and resonance of the instrument carrier. The resonance was much larger than the drill pipe vibration and its magnitude may depend on the structure of the instrument carrier. Preliminary results of the vibration mode, its amplitude, and comparison with current speed and direction, ships speed and depth of the sensor assembly are also shown to elucidate the cause of the vibration. These results give us an opportunity to establish installation methods, and to develop and refine sensors for the future long-term observatory emplacement.

    "TSUKIJI" is one of the biggest and most famous Free Fish Markets in the world, but there are many problems on the working condition because it was built about 60 years ago. Our investigation was held 1991 to 1993 to give some improvements regarding layout of buildings, working time, heat condition at refrigerator, working posture, and so on. We used a questionnaire on daily life and health care of workers, time study with measurement of heartbeats, and checklist (using Checklist for Improvement of Safety-Health and Working Conditions,' made by ILO). The main occupations in TSUKIJI were seller, buyer, delivery worker, and refrigerator maintenance worker. Their starting time was early in the morning, usually between 2:00 a.m. and 5:00 a.m., but the hardest one was delivery workers starting at 9:00 p.m. They used auto cargo car for carrying to shops from refrigerator or from auction places many times. Sellers had two different types of work. First, the seller set up the auction, numbering the fish (or cases of seafood), arranging them in order, and so on. The rest of the work was transaction of invoices, sometimes using VDU with almost sitting. These works did not look well balanced. Buyer of tuna cut if like lumber by electric saws did not have guard for protection and there were more than 200 machines. Overlooking the market by checklist, some problems were clarified, and suggestions for improvement include restructuring the whole layout of the market or reforming buildings, standardization of the cases, adjustment of health facilities, safety protection on tools and machines, management of working system, working posture, health care, and so on.

  20. New Era of Scientific Ocean Drilling

    The D/V Chikyu, committed to scientific ocean drilling since 2007, has completed thirteen IODP expeditions, and Chikyu's enhanced drilling technology gives us the means to reach deep targets, enhanced well logging, deep water riserless drilling, and state of the art laboratory. Chikyu recovered core samples from 2466 meters below sea floor (mbsf) in IODP Exp. 337, and drilled to 3058.5 mbsf in IODP Exp. 348, but these are still not the limit of Chikyu's capability. As deep as these depths are, they are just halfway to the 5200 mbsf plate boundary target for the NanTroSEIZE deep riser borehole. There are several active IODP proposals in the pipeline. Each has scientific targets requiring several thousand meters of penetration below the sea floor. Riser technology is the only way to collect samples and data from that depth. Well logging has been enhanced with the adoption of riser drilling, especially for logging-while-drilling (LWD). LWD has several advantages over wireline logging, and provides more opportunities for continuous measurements even in unstable boreholes. Because of the larger diameter of riser pipes and enhanced borehole stability, Chikyu can use several state-of-the-art downhole tools, e.g. fracture tester, fluid sampling tool, wider borehole imaging, and the latest sonic tools. These new technologies and tools can potentially expand the envelope of scientific ocean drilling. Chikyu gives us access to ultra-deep water riserless drilling. IODP Exp. 343/343T investigating the March 2011 Tohoku Oki Earthquake, explored the toe of the landward slope of the Japan Trench. This expedition reached the plate boundary fault target at more than 800 mbsf in water depths over 6900 m for logging-while-drilling, coring, and observatory installation. This deep-water drilling capability also expands the scientific ocean drilling envelope and provides access to previously unreachable targets. On top of these operational capabilities, Chikyu's onboard laboratory is

    The research vessel Chikyu is expanding new frontiers in science, technology, and international collaboration through deep-sea expedition. The Chikyu (length: 210 m, gross tonnage: 56752 tons) has advanced and comprehensive scientific research facilities. One of the scientific purposes of the vessel is to investigate into unexplored biosphere (i.e., undescribed extremophiles) on the Earth. Therefore, "the onboard laboratory" provides us systematic microbiological protocols with a physical containment situation. In parallel, the onboard equipments provide sufficient space for fifty scientists and technical support staff. The helicopter deck also supports various logistics through transporting by a large scale helicopter (See, http://www.jamstec.go.jp/chikyu/eng/). Since the establishment of Panel on Planetary Protection (PPP) in Committee on Space Research (COSPAR), we have an international consensus about the development and promulgation of planetary protection knowledge, policy, and plans to prevent the harmful effects of biological contamination on the Earth (e.g., Rummel, 2002). However, the matter to select a candidate location of initial quarantine at BSL4 level is often problematic. To answer the key issue, we suggest that international waters can be a meaningful option with several advantages to conduct initial onboard-biological quarantine investigation. Hence, the research vessel Chikyu is promising for further PPP requirements (e.g., Enceladus sample return project: Tsou et al., 2012).

    Integration of workplace employee health promotion (HP) and occupational health and safety (OHS) work into organizational quality improvement systems is suggested as a way to strengthen HP and OHS activities in an organization. The aim of this article was to study what consequences integration of HP, OHS and a quality improvement system called kaizen has on the frequency and type of HP and OHS activities. A quasi-experimental study design was used where an integration of the three systems for HP, OHS respectively kaizen, was performed at six intervention units at a Swedish hospital. The remaining six units served as controls. Document analysis of all employees' written improvement suggestions (kaizen notes) during 2013 was conducted. The findings show that the intervention group had more suggestions concerning HP and OHS (n = 114) when compared with the control group (n = 78) and a greater variety of HP and OHS suggestions. In addition, only the intervention group had included HP aspects. In both groups, most kaizen notes with health consideration had a preventive focus rather than rehabilitative. The intervention, i.e. the integration of HP, OHS and kaizen work, had a favourable effect on HP and OHS work when compared with the controls. The results of the study support that this system can work in practice at hospitals.

    Job performance and production related issues are important not only to successful vocational training and ultimate job placement for individuals with cognitive disabilities, but also for their ability to have expanded vocational options. This study hypothesized that the application of Kaizen philosophy, and poka-yoke techniques in particular, could create job opportunities and improve productivity of individuals with cognitive disabilities. Poka-yoke or error-proofing techniques are part of the collection of Kaizen techniques. Kaizen refers to continuous improvement in performance, cost/effectiveness, and quality. Kaizen strives to empower the worker, increase worker satisfaction, facilitate a sense of accomplishment, and thereby create pride-of-work. These techniques typically reduce the physical and cognitive demands of a task and thereby render the task more accessible. The job was a fuel clamp assembly. A redesigned assembly fixture was the poka-yoke intervention. Consistent with poka-yoke principles, the intervention improved the productivity of everyone attempting the assembly. In particular, the workers in this study showed an 80% increase in productivity and an average percent error drop from 52% to about 1% after the process redesign. Furthermore, the workers showed improved morale, self-esteem, and pride-of-work. Prior to the process redesign, only the higher functioning workers could successfully perform the assembly. After the redesign a greater number of workers could successfully perform the assembly. These results not only validated the study hypothesis, but demonstrated that the success facilitated by applying Kaizen techniques had similar results with individuals with cognitive disabilities as with nondisabled workers.

    Choleretic effects of 60 kinds of Chinese traditional medicine frequently used in clinical practice were investigated. Consequently, significant effects of choleretics were found in the methanol extracts of Ko-so-san, Intinko-to, Saiko-seikan-to, Hange-koboku-to, Antyu-san, Syo-kankyo-to, Keisi-syakuyaku-timo-to, Senkan-meimoku-to, Bohu-tusyo-san, Juzen-taiho-to, Jumi-haidoku-to Kami-syoyo-san and Hange-syasin-to. Water extracts of these Chinese traditional medicine had no such effect. Alteration of excretion of various biliary components after administration of the methanol extracts with the choleretic effect was examined, and with all medicines, bile acid excretion decreased and sodium and potassium excretions increased. Therefore, a medicine inducing choleresis involves some selective increases in the bile acid-independent fraction of bile flow. And after administration of methanol extracts of Keisi-syakuyaku-timo-to and Bohu-tusyo-san, lithogenic index, an index of saturation level of cholesterol, decreased significantly. Therefore, with these medicines, a dissolving effect on cholesterol gallstone is expected.

    To test the effects of integrating health protection and health promotion with a continuous improvement system (Kaizen) on proximal employee outcomes (health promotion, integration, and Kaizen) and distal outcomes (workability, productivity, self-rated health and self-rated sickness absence). Twelve units in a county hospital in Sweden were randomized to control or intervention groups using a quasiexperimental study design. All staff (approximately 500) provided self-ratings in questionnaires at baseline, and a 12- and 24-month follow-up (response rate, 79% to 87.5%). There was a significant increase in the proximal outcomes over time in the intervention group compared with the control group, and a trend toward improvement in the distal outcomes workability and productivity. Integration seems to promote staff engagement in health protection and promotion, as well as to improve their understanding of the link between work and health.

    D/V Chikyu implemented by CDEX/JAMSTEC joined IODP from 2007. Various LWD (Logging While Drilling) and wireline logging have been carried out in many expeditions and for various purposes. Significant features of logging in Chikyu expeditions are many use of LWD than wireline logging, and riser dirlling. riser selected specific tools for each scientific target, and 3) carried out various borehole experiments. LWD has been more popular than wireline logging in Chikyu expeditions, because its advantages match theirs science targets. The advantages are followings. 1) LWD has more opportunities for measurement in unstable borehole, such as in the series of Nankai trough drilling expeditions. 2) LWD realtime data allows us to make realtime interpretation and operational decision. Realtime interpretation was required to set obsevartory at the properposition. 3) LWD before coring allows us to make a strategy of spot coring.We can design coring intervals for our interest and core length to improve core recovery.Riser drilling brings us merits for logging. One is hole stability (good hole condition) and the other is the use of large diameter tools. Controled drilling mud in riser drilling system prevent mud invasion to formation and mitigates collapse of borehole wall. They reduce the risk of tool stack and improve data quality. Large diameter of riser pipe enhances variation of tool seizes. A couple of new tools were used for new measurement and improvement of the data quality. For example, SonicScanner (trademark of Schulumberger) successfully measured compressional and share velocity in very low velocities at the soft sediment, where it has been difficult to measure them with conventional DSI tool (Exp319). The stress and pore pressure in the borehole were measured with the wireline logging tool, (Schlumberger MDT). The single probe tool enable to measure temporal formation fluid pressure. The double packer tool enable to fracture test by sealing and pumping in the

    The India National Gas Hydrate Program Expedition 02 (NGHP-02) was conducted from 3-March-2015 to 28-July-2015 off the eastern coast of India using the deepwater drilling vessel Chikyu. The primary goal of this expedition was to explore for highly saturated gas hydrate occurrences in sand reservoirs that would become targets for future production tests. The first two months of the expedition were dedicated to logging-whiledrilling (LWD) operations, with a total of 25 holes drilled and logged. The next three months were dedicated to coring operations at 10 of the most promising sites. With a total of five months of continuous field operations, the expedition was the most comprehensive dedicated gas hydrate investigation ever undertaken.

    2009-10-01

    We investigated the stress field within the Nankai accretionary prism of southwestern Japan, where very-low-frequency (VLF) earthquakes occur associated with thrust faulting. A northwest-southeast azimuth of the maximum horizontal principal stress previously estimated from borehole breakouts in wells drilled in the region by deep-sea drilling vessel Chikyu suggests trench-normal shortening, although strike-slip and normal faulting are also possible within a thrust-dominated tectonic environment. We estimated stress orientations and stress ratios by using stress tensor inversion to derive moment tensor solutions for VLF earthquakes in three regions along the Nankai Trough: off Kumano, off Muroto, and Hyuga-nada. The stress orientations we obtained indicate that the regions off Kumano and off Muroto are within a transpressional stress regime with trench-normal shortening, whereas the Hyuga-nada region on the westernmost edge of the Nankai accretionary prism is in a reverse-faulting regime.

    Despite the prolific implementation of manufacturing systems, JIT principles, Kaizen events, and cycle time reduction programs over the past few years, high inventories still plague many companies. The assumption that implementing these principles and techniques will automatically result in inventory levels that satisfy management frequently proves to be false. Events like mergers, introduction of new competition, and a dropoff in business often trigger edicts to cut inventories. The cost of inventories also extends beyond the traditional accounting measurements to include hidden operating costs that everyone should want to eliminate. This article looks at the reasons for inventories and explores strategies for reducing them.

    A plant control diagnosis technology was developed to improve the performance of plant-wide control and maintain high productivity of plants. The control performance diagnosis system containing this technology picks out the poor performance loop, analyzes the cause, and outputs the result on the Web page. Meanwhile, the PID tuning tool is used to tune extracted loops from the control performance diagnosis system. It has an advantage of tuning safely without process changes. These systems are powerful tools to do Kaizen (continuous improvement efforts) step by step, coordinating with the operator. This paper describes a practical technique regarding the diagnosis system and its industrial applications.

    Research in the late 80's on technological companies that develop products of high value innovation, with sufficient speed and flexibility to adapt quickly to changing market conditions, gave rise to the new set of methodologies known as Agile Management Approach. In the current changing economic scenario, we considered very interesting to study the similarities of these Agile Methodologies with other practices whose effectiveness has been amply demonstrated in both the West and Japan. Strategies such as Kaizen, Lean, World Class Manufacturing, Concurrent Engineering, etc, would be analyzed to check the values they have in common with the Agile Approach.

    Because visual inspection systems are difficult to tune, they create many problems for the kaizen process. This results in increased development costs and time to assure that the inspection systems function properly. In order to improve inspection system development, we designed an easy-tuning system called a “Program-less” visual inspection system. The ROI macro command which consisted of eight kinds of shape recognition macro commands and decision, operation, control commands was built. Furthermore, the macro command editing executive system was developed by the operation of only the GUI without editing source program. The validity of the ROI macro command was proved by the application of 488 places.

    Japan is renowned for impeccable customer service (as anyone who's watched an apple get wrapped up like a crown jewel in a Tokyo grocery store will tell you). The Japanese concept of kaizen (constant improvement) is a fundamental reason for this, and for the enduring success of conglomerates such as Toyota, Honda, and Sony. From afar, you may think this trait is caused by something in the waters from Mt. Fuji, but many in the know credit the work of an American engineer named W. Edwards Deming as the catalyst for this movement. If his ideas could transform a nation, there's no question they can improve the patient satisfaction rates at your practice.

We analyzed the transfer process to assess distinct opportunities to enhance the overall transition of patient care. Methods We surveyed internal medicine residents and nocturnists to determine their satisfaction with transfers in terms of safety, efficiency, and usefulness of information provided at the time of transfer. After a kaizen event at which complementary goals for the institution and members of the study team were recognized and implemented, we resurveyed the group to evaluate improvement in the transfer process. Results The preintervention average satisfaction score was 1.18 (SD=0.46), while the postintervention score was 3.7 (SD=1.01). A t test showed a significant difference in the average scores between the preintervention and postintervention surveys (P<0.0001). Conclusions By including residents in the transfer calls (a result of the kaizen event), data were collected that facilitated fewer and higher quality handoffs that were performed in less time. In addition, the process resulted in increased awareness of the value of resident participation in institutional quality improvement projects. PMID:23267257

    The manufacturing industry has been using Lean Sigma for years in pursuit of continuous improvement to obtain a competitive advantage. The objectives of these efforts are to use the Lean techniques for reducing cycle times and the Six Sigma concepts for reducing product defects. The Iowa Business Council with several advocates worked with the University of Iowa Hospital and Clinics (UIHC) and two other Iowa hospitals to determine whether Lean Sigma is adaptable in healthcare. A team of 15 people at UIHC used the Kaizen Breakthrough Methodology over a five-day period in an aggressive identification and elimination of non-value added activities in Radiology CT scanning. The results exceeded the initial project objectives and indicated that Lean Sigma is applicable in healthcare. Overall, the Lean Sigma project increased revenue by approximately $750,000 per year. The Kaizen process proved to be successful and interesting. Within three days, the team installed new work flow processes. This implementation-oriented approach is what differentiates Lean Sigma from other quality improvement processes.

    The costs of investing in health care reform initiatives to improve quality and safety have been underreported and are often underestimated. This paper reports direct and indirect cost estimates for the initial phase of the province-wide implementation of Lean activities in Saskatchewan, Canada. In order to obtain detailed information about each type of Lean event, as well as the total number of corresponding Lean events, we used the Provincial Kaizen Promotion Office (PKPO) Kaizen database. While the indirect cost of Lean implementation has been estimated using the corresponding wage rate for the event participants, the direct cost has been estimated using the fees paid to the consultant and other relevant expenses. The total cost for implementation of Lean over two years (2012-2014), including consultants and new hires, ranged from $44 million CAD to $49.6 million CAD, depending upon the assumptions used. Consultant costs accounted for close to 50% of the total. The estimated cost of Lean events alone ranged from $16 million CAD to $19.5 million CAD, with Rapid Process Improvement Workshops requiring the highest input of resources. Recognizing the substantial financial and human investments required to undertake reforms designed to improve quality and contain cost, policy makers must carefully consider whether and how these efforts result in the desired transformations. Evaluation of the outcomes of these investments must be part of the accountability framework, even prior to implementation.

    Hilburn, Monty D.

    Successful lean manufacturing and cellular manufacturing execution relies upon a foundation of leadership commitment and strategic planning built upon solid data and robust analysis. The problem for this study was to create and employ a simple lean transformation planning model and review process that could be used to identify functional support staff resources required to plan and execute lean manufacturing cells within aerospace assembly and manufacturing sites. The lean planning model was developed using available literature for lean manufacturing kaizen best practices and validated through a Delphi panel of lean experts. The resulting model and a standardized review process were used to assess the state of lean transformation planning at five sites of an international aerospace manufacturing and assembly company. The results of the three day, on-site review were compared with baseline plans collected from each of the five sites to determine if there analyzed, with focus on three critical areas of lean planning: the number and type of manufacturing cells identified, the number, type, and duration of planned lean and continuous kaizen events, and the quantity and type of functional staffing resources planned to support the kaizen schedule. Summarized data of the baseline and on-site reviews was analyzed with descriptive statistics. ANOVAs and paired-t tests at 95% significance level were conducted on the means of data sets to determine if null hypotheses related to cell, kaizen event, and support resources could be rejected. The results of the research found significant differences between lean transformation plans developed by site leadership and plans developed utilizing the structured, on-site review process and lean transformation planning model. The null hypothesis that there was no difference between the means of pre-review and on-site cell counts was rejected, as was the null hypothesis that there was no significant difference in kaizen event plans.

    balance between risk, cost, and scientific impact is achieved. At least part of the dilling also is required to be a necessary precursor for future investigations in coming phases of Ocean Drilling. Presently IODP faces the challenges of tight budgetary constraints, increasing operating costs of their platforms, and the need to develop drilling schedules that allow off-contract work of the R/V Chikyu and R/V Joides Resolution drilling vessels. Chikyu will operate within IODP for an average of 7 months per year over a 5-year period with the goals of achieving major milestones in NantroSEIZE, maximizing the use of the vessel for riser drilling, and start a new IODP project that requires riser drilling. Joides Resolution will also operate an average of 7 months per year with the goal of optimizing operating days within the restrictions imposed by the prioritized science. Mission Specific Platform expeditions will be carried out once every two years on average, with the goal of pioneering drilling in new, challenging environments. For the first time in IODP history, operations of Chikyu, Joides Resolution and Mission Specific Platform expeditions will be conducted simultaneously in 2009. This new phase of operations provides an unprecedented chance of progress in scientific ocean drilling.

    The Okinawa Trough (OT) is a young and actively spreading back-arc basin, extending behind the Ryukyu arc-trench system in the southeastern margin of the East China Sea. The OT is believed to be in an initial rifting stage (starting from 6-9 Ma), prior to the normal/stable seafloor spreading which constitutes the main stage of back-arc basin formation. Two drilling cruises ‒ the IODP Exp. 331 and SIP CK14-04 D/V Chikyu Cruise (Exp. 907) in 2010 and 2014 ‒ were conducted at the Iheya North Knoll, middle OT. The Iheya North Knoll is a domal volcanic complex consisting of small volcanic bodies. On these cruises, pumiceous gravel and altered rhyolitic rocks, as well as hemi-pelagic sediments, hydrothermal clay and Kuroko-type ores, were recovered from the upper 200 m of the crust. From Feb. 11, 2016 to Mar. 17, 2016, the SIP CK16-01 (Exp. 908) D/V Chikyu cruise was conducted at Iheya North Knoll and the sediment-covered rifting center of the Iheya-Minor Ridge area, middle OT. The Iheya-Minor ridge area is also an active hydrothermal field, located 25 km southeast of the Iheya North Knoll. In this area, basaltic rocks are widely distributed, and drilling has confirmed that the basaltic materials continue to 120 m below the seafloor. From an igneous petrological point of view, the volcanic rocks in the Okinawa Trough are characterized by bimodal basaltic and rhyolitic compositions, with a compositional gap between SiO2 = 56-66 wt%. The origin of the rhyolitic rock has been interpreted as magmatic differentiation of basaltic magma. However, the existence of an active basalt-hosted hydrothermal field in the Iheya-Minor ridge area suggests the presence of hot basaltic rocks at a shallow position in the crust, and reaching recharged seawater at this depth. Furthermore, the composition of felsic rocks just after the compositional gap (SiO2 = 67 wt%) is very similar to that of the minimum melt of a granitic system, and experimental partial melt of hydrous basalt. Therefore

    First of its kind in scientific drilling history, NanTroSEIZE is complex drilling project with multiyear and multistage effort, aimed at drilling, coring, logging, and instrumenting the seismogenic zone of an active subduction margin, in a region thought to generate megathrust earthquakes of magnitude >8.0 on the moment-magnitude scale. Four stages are divided to realize ambitious scientific objectives using CHIKYU, most advanced floating laboratory in scientific drilling. Unlike the industry use of logging technology, expeditions in the scientific ocean drilling used logging data in much wider applications by working various software onboard Chikyu and laboratory measurements of core-cuttings throughout single or multiple expeditions, ranging from 40 to 56 days. Instead of traditional full coring, logging-while-drilling was made across the transect at the beginning to quickly access the geological and structural information from the formation. In line with changing tactic of heavy use on logging, four working groups were organized and worked on the logging data; lithologic characterization/lithostratigraphy, physical properties and hydrogeology, structural geology and geomechanics and cuttings/core-log-seismic integration (CLSI). During the Stage 1 with three expeditions, a transect of eight sites were drilled frontal thrust region, the midslope megasplay fault region, and the Kumano forearc basin region using full suite of MWD-LWD and made coring and downhole measurements. Stage 2 composed of two expeditions with the aims of building on the results of Stage 1 and preparing for later observatory installations for long-term monitoring of deformation at the updip limit of the seismogenic zone. Extensive logging program at riser site, first ever in scientific ocean drilling history, includes conventional wireline logging with long-awaited formation stress measurements and wide-angle walk-away VSP with longest-ever offset to have better

    On the March 2013, Japan Oil, Gas and Metals National Corporation (JOGMEC) has conducted the first gas production test from methane hydrate deposits in the Nankai Trough offshore Japan. In the Eastern Nankai Trough area off the Pacific coast of Japan, highly concentrated methane hydrate deposits were discovered in Pleistocene turbidite sediments.. Along with geological information, structure and physical properties of the sediments are essential information to understand the nature and origin of the deposits, and preserving those in-situ values in core samples for laboratory testing on surface is a quite important scientific challenge. To solve the problem, JOGMEC and JAMSTEC have developed a pressure coring device and utilized it on D/V Chikyu for our coring operation before the production test. In this operation, we obtained two types of cores; one is the dissociation preserved core by rapidly cooled by emerging into liquid nitrogen (LN2 core), the other is stored in special pressure vessels without depressurizing and kept under original pressure and temperature (pressure core). Here the summary of LN2 core sample analyses, such as X-ray CT, p-wave velocity, particle analysis, permeability, mechanical properties, and gas composition, is presented. Also future analysis plan for pressure core is explained. This work was supported by funding from the Research Consortium for Methane Hydrate Resources in Japan (MH21 Research Consortium) planned by METI.

    We present results of electrical conductivity and P-wave velocity measurements in discrete samples processed onboard Chikyu during Nantroseize expeditions 315 and 316 in the Mega Splay fault and Frontal Thrust of the Nankai accretionary prism. Quasi cubes of 20 mm thickness nominally saturated with seawater were measured across the three parallel sets of faces, first for electrical conductivity, then for P-wave velocity. Average properties and their anisotropies appeared to show some sensitivity to both lithological and fault related features. Overall, strong transverse anisotropy due to sedimentary compaction was observed for both properties with minimum electrical conductivity and P-wave velocity along the vertical core axis direction. Within the horizontal plane perpendicular to the core axis, slight anisotropies were also measured, which are likely related to tectonically driven horizontal shortening, affecting noticeably the original compaction fabric. In order to get some structural insight, samples were reoriented in our laboratories using alternative field demagnetization technique and the in-plane (i.e. perpendicular to the core axis) data rotated accordingly. For the P-wave anisotropy, initial cubes were shaped into polyhedrons in order to get even more accurate estimates. These additional measurements allowed for retrieving for each sample the 3 principal values and vectors of the best fitting ellipsoidal function. Resulting stereoplots were then compared with electrical resistivity, magnetic susceptibility (AMS) and structural data.

    Kochi Core Center (KCC) is one of the 3 IODP core repositories in the world, and is in-charge of curating core materials collected/to be collected from most of the Indian Ocean, west Pacific Ocean and Bering Sea. Curation of IODP core material in the KCC began in 2007 as it started receiving 83 km of Legacy cores from the other IODP core repositories. Since then the KCC has not only maintained curatorial standards of the IODP, but also added many services for convenience of the IODP researchers that include curation of cuttings and deep frozen aliquots of cores, open access to logging equipment in the KCC for core measurements, virtual core library to provide quick online access to 3-D XCT images of the cores collected by the D/V Chikyu, online summary of the cores being curated in the KCC, and up-to-date online images of working half to show status of samples available for prospective users. With its existing stock of 104 km of the IODP & Legacy cores and cores to be recovered from the Indian Ocean in near future by the JOIDES Resolution, and a huge new reefer building with storage capacity of ca. 150 km core becoming part of the KCC this August, the KCC is bound to play a significant role in promoting earth and biogeo-sciences throughout the world, especially in neighboring Asian countries.

    Stringent contamination controls are essential to any type of microbiological investigation, and are particularly challenging in ocean drilling, where samples are retrieved from hundreds of meters below the seafloor. In summer 2012, Integrated Ocean Drilling Expedition 337 aboard the Japanese vessel Chikyu pioneered the use of chemical tracers in riser drilling while exploring the microbial ecosystem of coalbeds 2 km below the seafloor off Shimokita, Japan. Contamination tests involving a perfluorocarbon tracer that had been successfully used during past riserless drilling expeditions were complemented by DNA-based contamination tests. In the latter, likely microbial contaminants were targeted via quantitative polymerase chain reaction assays using newly designed, group-specific primers. Target groups included potential indicators of (a) drilling mud viscosifiers (Xanthomonas, Halomonas), (b) anthropogenic wastewater (Bifidobacterium, Blautia, Methanobrevibacter), and (c) surface seawater (SAR 11, Marine Group I Archaea). These target groups were selected based on past evidence suggesting viscosifiers, wastewater, and seawater as the main sources of microbial contamination in cores retrieved by ocean drilling. Analyses of chemical and molecular tracers are in good agreement, and indicate microorganisms associated with mud viscosifiers as the main contaminants during riser drilling. These same molecular analyses are then extended to subseafloor samples obtained during riserless drilling operations. General strategies to further reduce the risk of microbial contamination during riser and riserless drilling operations are discussed.

  3. Lean-driven improvements slash wait times, drive up patient satisfaction scores.

    2012-07-01

    Administrators at LifePoint Hospitals, based in Brentwood, TN, used lean manufacturing techniques to slash wait times by as much as 30 minutes and achieve double-digit increases in patient satisfaction scores in the EDs at three hospitals. In each case, front-line workers took the lead on identifying opportunities for improvement and redesigning the patient-flow process. As a result of the new efficiencies, patient volume is up by about 25% at all three hospitals. At each hospital, the improvement process began with Kaizen, a lean process that involves bringing personnel together to flow-chart the current system, identify problem areas, and redesign the process. Improvement teams found big opportunities for improvement at the front end of the flow process. Key to the approach was having a plan up front to deal with non-compliance. To sustain improvements, administrators gather and disseminate key metrics on a daily basis.

    No longer convinced that their viewpoint on quality is the only one, different stakeholders in the health-care arena are sharing perspectives to piece together the quality picture. Although still preoccupied with the cost of health care, purchasers are concerned about value--efficiency, appropriateness, and effectiveness--as well as price. Faced with evidence of medically unnecessary procedures and unexamined medical theory, practitioners are searching for appropriateness guidelines, useful outcome measures, and methods to elicit informed patient preferences about elective surgeries. Underlying this search for reliable indicators of quality--now expanded to include patient satisfaction--is a new interest in the Japanese notion of "Kaizen" or continuous quality improvement. The end product of this ferment may determine whether good medicine drives out the bad--or vice versa.

    This is an introduction to the major concepts in total quality management, a loose collection of management approaches that focus on continuous improvement of processes, guided by routine data collection and adjustment of the processes. Customer focus and involvement of all members of an organization are also characteristics commonly found in TQM. The seventy-five-year history of the movement is sketched from its beginning in statistical work on quality assurance through the many improvements and redefinitions added by American and Japanese thinkers. Essential concepts covered include: control cycles, focus on the process rather than the defects, the GEAR model, importance of the customer, upstream quality, just-in-time, kaizen, and service quality.

    Few reports have documented the effectiveness of Lean quality improvement in changing anatomic pathology patient safety. We used Lean methods of education; hoshin kanri goal setting and culture change; kaizen events; observation of work activities, hand-offs, and pathways; A3-problem solving, metric development, and measurement; and frontline work redesign in the accessioning and gross examination areas of an anatomic pathology laboratory. We compared the pre- and post-Lean implementation proportion of near-miss events and changes made in specific work processes. In the implementation phase, we documented 29 individual A3-root cause analyses. The pre- and postimplementation proportions of process- and operator-dependent near-miss events were 5.5 and 1.8 (P < .002) and 0.6 and 0.6, respectively. We conclude that through culture change and implementation of specific work process changes, Lean implementation may improve pathology patient safety.

    2013-11-01

    The paper starts summarizing the claims of Beer's viable systems model to identify five issues any viable organizations has to deal with in an unequivocal hierarchical structure of five interrelated systems. Then the evidence is introduced for additional issues and related viable structures of organizations, which deviate from Beer's model. These issues are: (1) the establishment and (2) evolution of an organization; (3) systems for independent top-down control (like "Six Sigma"); (4) systems for independent bottom-up correction of performance problems (like "Kaizen"), both working outside a hierarchical structure; (5) pull production systems ("Just in Time") and (6) systems for checks and balances of top-level power (like boards and shareholder meetings). Based on that an evolutionary approach to organizational cybernetics is outlined, addressing the establishment of organizations and possible courses of developments, including recent developments in quality and production engineering, as well as problems of setting and changing goal values determining organizational policies.

    HITEC 2 (Health Improvement through Employee Control 2) is the follow-up to HITEC, a participatory action research (PAR) program that integrates health and work conditions interventions designed by the workforce. HITEC 2 compares intervention programs between two correctional sites, one using a pure workforce level design team and the other using a more structured and time delineated labor-management kaizen effectiveness team. HITEC 2 utilizes a seven step participatory Intervention Design and Analysis Scorecard (IDEAS) for planning interventions. Consistent with PAR, process and intervention efficacy measures are developed and administered through workforce representation. Participation levels, robustness of participatory structures and sophistication of interventions have increased at each measured interval. Health comparisons between 2008 and 2013 showed increased hypertension, static weight maintenance, and increased 'readiness to change'. The PAR approaches are robust and sustained. Their long-term effectiveness in this population is not yet clear. Copyright © 2015 Elsevier Ltd and The Ergonomics Society. All rights reserved.

    The success of quality-improvement projects relies heavily on both project design and the metrics chosen to assess change. In Part II of this three-part American Thoracic Society Seminars series, we begin by describing methods for determining which data to collect, tools for data presentation, and strategies for data dissemination. As Avedis Donabedian detailed a half century ago, defining metrics in healthcare can be challenging; algorithmic determination of the best type of metric (outcome, process, or structure) can help intensive care unit (ICU) managers begin this process. Choosing appropriate graphical data displays (e.g., run charts) can prompt discussions about and promote quality improvement. Similarly, dashboards/scorecards are useful in presenting performance improvement data either publicly or privately in a visually appealing manner. To have compelling data to show, ICU managers must plan quality-improvement projects well. The second portion of this review details four quality-improvement tools-checklists, Six Sigma methodology, lean thinking, and Kaizen. Checklists have become commonplace in many ICUs to improve care quality; thinking about how to maximize their effectiveness is now of prime importance. Six Sigma methodology, lean thinking, and Kaizen are techniques that use multidisciplinary teams to organize thinking about process improvement, formalize change strategies, actualize initiatives, and measure progress. None originated within healthcare, but each has been used in the hospital environment with success. To conclude this part of the series, we demonstrate how to use these tools through an example of improving the timely administration of antibiotics to patients with sepsis.

    The relationship of staff satisfaction and engagement to organizational success, along with the integral influence of frontline managers on this dimension, is well established in health care and other industries. To specifically address staff engagement, Virginia Mason Medical Center, an integrated, single-hospital health system, developed an approach that involved leaders, through the daily use of standard work for leaders, as well as staff, through a Lean-inspired staff idea system. Kaizen Promotion Office (KPO) staff members established three guiding principles: (1) Staff engagement begins with leader engagement; (2) Integrate daily improve- ment (kaizen) as a habitual way of life not as an add-on; and (3) Create an environment in which staff feel psycho- logically safe and valued. Two design elements--Standard Work for Leaders (SWL) and Everyday Lean Ideas (ELIs) were implemented. For the emergency department (ED), an early adopter of the staff engagement work, the challenge was to apply the guiding principles to improve staff engagement while improving quality and patient and staff satisfaction, even as patient volumes were increasing. Daily huddles for the KPO staff members and weekly leader rounds are used to elicit staff ideas and foster ELIs in real time. Overall progress to date has been tracked in terms of staff satisfaction surveys, voluntary staff turnover, adoption of SWL, and testing and implementation of staff ideas. For example, voluntary turnover of ED staff decreased from 14.6% in 2011 to 7.5% in 2012, and 2.0% in 2013. Organizationwide, at least 800 staff ideas are in motion at any given time, with finished ones posted in an idea supermarket website. A leadership and staff engagement approach that focuses on SWL and on capturing staff ideas for daily problem solving and improvement can contribute to organization success and improve the quality of health care delivery.

    The workplace has been suggested as an important arena for health promotion, but little is known about how the organizational setting influences the implementation of interventions. The aims of this study are to evaluate implementation fidelity in an organizational-level occupational health intervention and to investigate possible explanations for variations in fidelity between intervention units. The intervention consisted of an integration of health promotion, occupational health and safety, and a system for continuous improvements (Kaizen) and was conducted in a quasi-experimental design at a Swedish hospital. Implementation fidelity was evaluated with the Conceptual Framework for Implementation Fidelity and implementation factors used to investigate variations in fidelity with the Framework for Evaluating Organizational-level Interventions. A multi-method approach including interviews, Kaizen notes, and questionnaires was applied. Implementation fidelity differed between units even though the intervention was introduced and supported in the same way. Important differences in all elements proposed in the model for evaluating organizational-level interventions, i.e., context, intervention, and mental models, were found to explain the differences in fidelity. Implementation strategies may need to be adapted depending on the local context. Implementation fidelity, as well as pre-intervention implementation elements, is likely to affect the implementation success and needs to be assessed in intervention research. The high variation in fidelity across the units indicates the need for adjustments to the type of designs used to assess the effects of interventions. Thus, rather than using designs that aim to control variation, it may be necessary to use those that aim at exploring and explaining variation, such as adapted study designs.

    The workflow and chemotherapy preparation turnaround times at an adult infusion clinic were evaluated to identify opportunities to optimize workflow and efficiency. A three-phase study using Lean Six Sigma methodology was conducted. In phase 1, chemotherapy turnaround times in the adult infusion clinic were examined one year after the interim goal of a 45-minute turnaround time was established. Phase 2 implemented various experiments including a five-day Kaizen event, using lean principles in an effort to decrease chemotherapy preparation turnaround times in a controlled setting. Phase 3 included the implementation of process-improvement strategies identified during the Kaizen event, coupled with a final refinement of operational processes. In phase 1, the mean turnaround time for all chemotherapy preparations decreased from 60 to 44 minutes, and a mean of 52 orders for adult outpatient chemotherapy infusions was received each day. After installing new processes, the mean turnaround time had improved to 37 minutes for each chemotherapy preparation in phase 2. In phase 3, the mean turnaround time decreased from 37 to 26 minutes. The overall mean turnaround time was reduced by 26 minutes, representing a 57% decrease in turnaround times in 19 months through the elimination of waste and the implementation of lean principles. This reduction was accomplished through increased efficiencies in the workplace, with no addition of human resources. Implementation of Lean Six Sigma principles improved workflow and efficiency at an adult infusion clinic and reduced the overall chemotherapy turnaround times from 60 to 26 minutes.

    A series of scientific drilling expeditions is in operation in the Nankai Trough to reveal the faulting mechanism of the magathrust earthquakes, through clarifying composition, fine structure, mechanical behavior, and environmental variables of the seismogenic faults. In the studied area, extensive seismic surveys for site characterization have been made to image detailed geometry of the fault complex in the accretionary prism as well as Vp distribution around the faults. Although these previous surveys provided invaluable information for understanding seismotectonic processes in this subduction zone, more complete knowledge is needed to be acquired to predict dynamic behavior of the faults, such as geometrical irregularities in short wavelength, Vs and seismic attenuation which are sensitive to fluid distribution in and around fault zones. It is expected that estimation of these parameters would be improved considerably by a seismic exploration using a vertical array of seismographs installed in a deep borehole (VSP: vertical seismic profiling). In July 2009, we made a VSP at one of the drilling sites located just above the rupture area of the 1994 Tonankai Earthquake (M 8.1), during the IODP Exp.319. The well site of our VSP was made by the riser drilling of D/V Chikyu. The seismic array, lowered from Chikyu into the hole, was composed of a three-component accelerometer and vertical separation of the array elements was 15.12 m. The VSP was composed of offset VSP and zero-offset VSP. In the offset VSP, a tuned airgun array towed by R/V Kairei was shot along one straight line (walk-away VSP) and another circular line (walk-around VSP) and seismic signals were recorded by an array consisting of 16 elements installed from 907 to 1,135 m in depth from seafloor. The object of the walk-away VSP is to obtain fine image of the faults using reflection arrivals with less attenuation. It is also expected to obtain spatial variation of Vs from arrival time tomography of

    Integrated Ocean Drilling Program (IODP) Expedition 337 aboard the drilling vessel Chikyu in summer 2012 was the first IODP expedition to drill into a deeply buried hydrocarbon system by riser drilling and, in the process, extended the depth record of scientific ocean drilling to 2466 meters below seafloor (mbsf). A main scientific goal of Expedition 337 was to explore microbial communities associated with deeply buried coalbeds 2 km below the seafloor at Site C0020 off the Shimokita Peninsula of Japan, northwestern coast of the Pacific Ocean. Four lithological units were defined according to sedimentological observations (Inagaki et al. 2012). Temperature measurements during wireline logging revealed in-situ temperatures in the range habitable for life, with ~40-45°C in 2km-deep coalbeds and 60°C at the bottom of the hole. To determine potential sulfate reduction rates (pSRRs) throughout the lower half of the borehole (1200-2466 mbsf; Units II - IV), we prepared slurries from fresh core material in artificial seawater medium containing 1 mM of sulfate and incubated these onboard with 35S-labeled sulfate at approximate in-situ temperatures (i.e., 25, 35, and 45°C). A duplicate set of incubations was started from each sample, one with only N2 in the headspace, and one with N2 + CH4 in the headspace. We incubated samples with 3.7 MBq 35S for a period of 10 days to achieve a detection limit of ca. 10 fmol sulfate cm-3 d-1. pSRRs were close to the detection limit in Unit II and increased by two orders of magnitude up to 2 pmol cm-3 d-1 in the coal-bearing strata (Unit III), decreasing again below in Unit IV. Maximum rates in Unit III reached values similar to those determined during the Chikyu shakedown cruise at 350 mbsf at the same site in 2006. In contrast to the pSRRs determined previously, however, addition of methane did not stimulate pSRRs, suggesting that potential sulfate reduction was supported by electron donors other than methane. The increase of pSRR in

    The first wireline logging, downhole stress measurement, and two-ship walkaway VSP (Vertical Seismic Profiling) were conducted in the riser drilled hole during IODP Expedition 319 in 2009. The hole C0009 is first riser drilling hole in ODP/IODP history by JAMSTEC D/V Chikyu. The expedition 319 is one of series of NanTroSEIZE Project, which goal is to reveal earthquake mechanism in Nankai trough seismogenic zone in Japan. The hole C0009 is drilled at TD 1603.7mbsf under 2054m sea water. Sampling cores, cutting analysis, gas monitoring, wireline logging, downhole stress measurement, and two-ship walkaway VSP (Vertical Seismic Profiling) were conducted. This presentation report the operational planning, results and reality. IODP standard wireline logging items: natural gamma-ray, resistivity, density, porosity, sonic velocity, resistivity image were measured. The advantages of riser dilled hole against riserless drilled hole for wireline logging are 1) stable hole condition, 2) accurate environmental correction by controlled drilling mud, and 3) large variation of tool selection because of regular hole size instead of slimhole by conventional IODP riser drilling. A couple of new tools were used for new measurement and improvement of the data quality. The SonicScanner (trademark of Schulumberger) successfully measured compressional and share velocity in very low velocities at the soft sediment, where it has been difficult to measure them with conventional DSI tool. The stress and pore pressure in the borehole were measured with the wireline logging tool, (Schlumberger MDT). The single probe tool enable to measure temporal formation fluid pressure. The double packer tool enable to fracture test by sealing and pumping in the borehole. These in-situ measurement and stress experiment data are very important to understand physical properties and mechanism of fault zone. Super long offset walkaway VSP was conducted to reveal detail subsurface structure and velocity

    The Pacific plate is surrounded by circum-Pacific active margin, along which volcanic and seismic activities are very high. Ultra-Mega-Earthquakes (=UMEs, M>9.0) are occasionally observed along the margin, where sedimentary rocks of subducting slaves contact with the accreted sedimentary rocks of subducted slaves. But, those UME have never been occured along western Pacific islandarc-trench system including Izu-Ogasawara (=Bonin)-Mariana-Yap-Palau-Philippine-Tonga-Kermadec Trenches. I assume that the geological and petrological characteristics of the subduction boundaries are very important to understand those different seismic activities. Along the above mentioned trench inner wall, especially in the southern Mariana, mantle peridotites are widely distributed. Subducting slave contacts directly with the olivine dominant mantle peridotites of subducted slave, serpentinite layer can be deposited easily under hydrous oceanic sub-bottom environment and very slippery subduction boundaries are left along the subduction zone.On the other hand, those geological evidences give us some ideas on how to avoid UMEs in the Japanese Islands along Japan Trench and Nankai Trough in future. We will be able to change artificially from normal subduction boundaries with asperity zone into slippery subduction boundaries with serpentine layer, by means of serpentine mud injection toward the subduction boundaries interior by combining the following improved drilling technologies A and B. (A) Deep Sea Drilling Vessel CHIKYU has a drilling ability to reach subduction boundary with asperity zone in the Nankai Trough. (B) Advanced drilling technology in the shale gas industry is tremendous, that is, after one vertical deep drilling, horizontal drilling towards several direction are performed, then shale gas is collected by hydraulic fracturing method. I hope that, after several generations, our posterity will be able to avoid UMEs by continuous serpentine mud injection.

    Carbon monoxide (CO) is the simplest oxocarbon generated by the decomposition of organic compounds, and it is expected to be in marine sediments in substantial amounts. However, the availability of CO in the deep subseafloor sedimentary biosphere is largely unknown even though anaerobic oxidation of CO is a thermodynamically favourable reaction that possibly occurs with sulphate reduction, methanogenesis, acetogenesis and hydrogenesis. In this study, we surveyed for the first time the distribution of the CO dehydrogenase gene (cooS), which encodes the catalytic beta subunit of anaerobic CO dehydrogenase (CODH), in subseafloor sediment-core samples from the eastern flank of the Juan de Fuca Ridge, Mars-Ursa Basin, Kumano Basin, and off the Shimokita Peninsula, Japan, during Integrated Ocean Drilling Program (IODP) Expeditions 301, 308 and 315 and the D/V Chikyu shakedown cruise CK06-06, respectively. Our results show the occurrence of diverse cooS genes from the seafloor down to about 390 m below the seafloor, suggesting that microbial communities have metabolic functions to utilize CO in anoxic microbial ecosystems beneath the ocean floor, and that the microbial community potentially responsible for anaerobic CO oxidation differs in accordance with possible energy-yielding metabolic reactions in the deep subseafloor sedimentary biosphere. Little is known about the microbial community associated with carbon monoxide (CO) in the deep subseafloor. This study is the first survey of a functional gene encoding anaerobic carbon monoxide dehydrogenase (CODH). The widespread occurrence of previously undiscovered CO dehydrogenase genes (cooS) suggests that diverse micro-organisms are capable of anaerobic oxidation of CO in the deep subseafloor sedimentary biosphere. © 2017 The Society for Applied Microbiology.

  19. Using DSDP/ODP/IODP core photographs and digital images in the classroom

    Since the late 1960's, several scientific ocean drilling programmes have been uncovering the history of the Earth hidden beneath the seafloor. The adventure began in 1968 with the Deep Sea Drilling Project (DSDP) and its special drill ship, the Glomar Challenger. The next stage was the Ocean Drilling Program (ODP) launched in 1985 with a new drill ship, the JOIDES Resolution. The exploration of the ocean seafloor continued, between 2003 and 2013, through the Integrated Ocean Drilling Program (IODP). During that time, in addition to the JOIDES Resolution, operated by the US, the scientists had at their service the Chikyu, operated by Japan, and Mission-Specific-Platforms, funded and implemented by the European Consortium for Ocean Research Drilling. Currently, scientific ocean drilling continues through the collaboration of scientists from 25 nations within the International Ocean Discovery Program (IODP). Over the last 50 years, the scientific ocean drilling expeditions conducted by these programmes have drilled and cored more than 3500 holes. The numerous sediment and rock samples recovered from the ocean floor have provided important insight on the active biological, chemical, and geological processes that have shaped the Earth over millions of years. During an expedition, once the 9.5-meter long cores arrive from the seafloor, the technicians label and cut them into 1.5-meter sections. Next, the shipboard scientists perform several analysis using non-destructive methods. Afterward, the technicians split the cores into two halves, the "working half", which scientists sample and use aboard the drilling platform, and the "archive half", which is kept in untouched condition after being visually described and photographed with a digital imaging system. The shipboard photographer also takes several close-up pictures of the archive-half core sections. This work presents some examples of how teachers can use DSDP/ODP/IODP core photographs and digital images, available

    P-wave velocity is an important parameter to estimate gas hydrate saturation in sediments. In this study, the relationship between gas hydrate saturation and P-wave velocity have been analyzed using natural hydrate-bearing-sediments obtained in the Eastern Nankai Trough, Japan. The sediment samples were collected by the Hybrid Pressure Coring System developed by Japan Agency for Marine-Earth Science and Technology during June-July 2012, aboard the deep sea drilling vessel CHIKYU. P-wave velocity was measured on board by the Pressure Core Analysis and Transfer System developed by Geotek Ltd. The samples were maintained at a near in-situ pressure condition during coring and measurement. After the measurement, the samples were stored core storage chambers and transported to MHRC under pressure. The samples were manipulated and cut by the Pressure-core Non-destructive Analysis Tools or PNATs developed by MHRC. The cutting sections were determined on the basis of P-wave velocity and visual observations through an acrylic window equipped in the PNATs. The cut samples were depressurized to measure gas volume for saturation calculations. It was found that P-wave velocity correlates well with hydrate saturation and can be reproduced by the hydrate frame component model. Using pressure cores and pressure core analysis technology, nondestructive and near in-situ correlation between gas hydrate saturation and P-wave velocity can be obtained. This study was supported by funding from the Research Consortium for Methane Hydrate Resources in Japan (MH21 Research Consortium) planned by the Ministry of Economy, Trade and Industry (METI), Japan.

    Investigations of Tectonics, Fluids, and the Seismogenic Zone are three disciplines that have driven convergent margin drilling. Each of these major themes sequentially evolved as centerpieces of drilling as the intellectual framework and the requisite technologies developed. Each remains active today. In the 1970s and early 1980s, initial results from testing plate tectonic theory defined the nature of progressive accretion, and conversely, tectonic erosion at convergent margins. With the more robust D/V JOIDES Resolution, investigation of fluid pressure, compositions, migration paths, and sediment/rock permeability became possible. 3D seismic data, first available in the early 1990s, detailed fluid migration paths inferred from porewater geochemical anomalies, emphasizing the importance of faults as fluid conduits. 3D seismic volumes also resulted in extraordinary insights on the structure and tectonics of convergent margins. In the mid 1990s packer testing and long-term monitoring of fault zones provided the first estimates of in situ fluid pressures, permeabilities, and variation of the latter with effective stress. Experimental studies, and hydrological and geomechanical modeling have provided critical perspectives on the observational data. During the late 1990s and 2000s the convergent margin community focused on earthquake processes in the Seismogenic Zone Experiment (SEIZE). Understanding of tectonics and fluids, plus monitoring, 3D seismic imaging, Logging While Drilling technology, and D/V Chikyu riser drilling capability have all contributed to emergent accomplishments of SEIZE. Some key results of this program include 1) estimates of material flux into the seismogenic zone, 2) measurement of stress orientation and magnitude across the margin of SW Japan, 3) recognition of high velocity fault slip at shallow depths, 4) correlation of monitored variations in fluid pressure and composition with seismic events, and 5) the initiation of a deep riser hole

    The Integrated Ocean Drilling Program (IODP) Expedition 337 was the first expedition dedicated to subseafloor microbiology that used riser-drilling technology with the drilling vessel Chikyu. The drilling Site C0020 is located in a forearc basin formed by the subduction of the Pacific Plate off the Shimokita Peninsula, Japan, at a water depth of 1180 m. Primary scientific objectives during Expedition 337 were to study the relationship between the deep microbial biosphere and a series of ˜ 2 km deep subseafloor coalbeds and to explore the limits of life in the deepest horizons ever probed by scientific ocean drilling. To address these scientific objectives, we penetrated a 2.466 km deep sedimentary sequence with a series of lignite layers buried around 2 km below the seafloor. The cored sediments, as well as cuttings and logging data, showed a record of dynamically changing depositional environments in the former forearc basin off the Shimokita Peninsula during the late Oligocene and Miocene, ranging from warm-temperate coastal backswamps to a cool water continental shelf. The occurrence of small microbial populations and their methanogenic activity were confirmed down to the bottom of the hole by microbiological and biogeochemical analyses. The factors controlling the size and viability of ultra-deep microbial communities in those warm sedimentary habitats could be the increase in demand of energy and water expended on the enzymatic repair of biomolecules as a function of the burial depth. Expedition 337 provided a test ground for the use of riser-drilling technology to address geobiological and biogeochemical objectives and was therefore a crucial step toward the next phase of deep scientific ocean drilling.

    We report here the global-scale assessment of both fresh and saline groundwater discharges based solely on observational data. Prior estimates have been limited to various water balance and hydrodynamic modeling calculations and range over orders of magnitude. Our observations suggest the global volumes of fresh groundwater discharge and recirculated seawater per unit shoreline length depending on the distance from the shoreline, precipitation, and seawater depth. On a world-wide scale, these flows are compared with the global river discharge. We show via automated measurements that precipitation and wave pumping are important controls of terrestrial (fresh) and marine-induced (recirculated seawater) subterranean flows, respectively. The Groundwater Resources Assessment under the Pressures of Humanity and Climate Changes (GRAPHIC) Project, an initiative of UNESCO International Hydrological Programme (IHP), seeks to improve the understanding and management of groundwater as a vital contributor to the global water cycle, ecosystems and communities, under changing climatic and anthropomorphic regimes. GRAPHIC focuses on variations of the flows, stocks, and quality of groundwater recharge, discharge and storage and on groundwater-related management and policy (http://www.chikyu.ac.jp/USE/GRAPHIC/GRAPHIC.htm). This GRAPHIC project will deal with groundwater resources assessment and future forecasting under the various pressures of humanity and climate changes. The structure of the GRAPHIC project has been divided into; (A) Subjects; thematic, cross-region issues, (B) Methods; methodological approaches (1:Database and Monitoring, 2:Satelite GRACE (Gravity Recovery and Climate Experiment), 3:Modeling and Simulation, 4:Paleohydrology), and (C) Regions; representative geographical areas, where pilot studies will be made.

    "A meta-enzyme approach" is proposed as an ecological enzymatic method to explore the potential functions of microbial communities in extreme environments such as the deep marine subsurface. We evaluated a variety of extra-cellular enzyme activities of sediment slurries and isolates from a deep subseafloor sediment core. Using the new deep-sea drilling vessel "Chikyu", we obtained 365 m of core sediments that contained approximately 2% organic matter and considerable amounts of methane from offshore the Shimokita Peninsula in Japan at a water depth of 1,180 m. In the extra-sediment fraction of the slurry samples, phosphatase, esterase, and catalase activities were detected consistently throughout the core sediments down to the deepest slurry sample from 342.5 m below seafloor (mbsf). Detectable enzyme activities predicted the existence of a sizable population of viable aerobic microorganisms even in deep subseafloor habitats. The subsequent quantitative cultivation using solid media represented remarkably high numbers of aerobic, heterotrophic microbial populations (e.g., maximally 4.4x10(7) cells cm(-3) at 342.5 mbsf). Analysis of 16S rRNA gene sequences revealed that the predominant cultivated microbial components were affiliated with the genera Bacillus, Shewanella, Pseudoalteromonas, Halomonas, Pseudomonas, Paracoccus, Rhodococcus, Microbacterium, and Flexibacteracea. Many of the predominant and scarce isolates produced a variety of extra-cellular enzymes such as proteases, amylases, lipases, chitinases, phosphatases, and deoxyribonucleases. Our results indicate that microbes in the deep subseafloor environment off Shimokita are metabolically active and that the cultivable populations may have a great potential in biotechnology.

    The marine deep biosphere remains as the least studied of all of Earth's habitats and is inadequately understood, but is extremely important to understand the impacts that microbes have on global biogeochemical cycles. Sediment samples were obtained during IODP Expedition 337 in the western Pacific Ocean, from 1,498 meters below the seafloor (mbsf; samples 6R3), 1,951-1,999 mbsf (19R1), and 2,406 mbsf (29R7). These samples were initially mixed with marine broth and cultivated under anaerobic conditions at pressure of 35 MPa (megapascal) and temperatures of 35° C, 45° C, and 55° C for 3 months on board the Chikyu. Single colonies were isolated via plating on marine broth. Then, six strains of bacteria were identified, 6R3-1, 6R3-15, 19R1-5, 29R7-12B, 29R7-12M, and 29R7-12S. The six strains were then examined for optimal growth temperature and pressure. These organisms are Gram-positive, spore-forming, facultative anaerobic piezophilic bacteria. Major fatty acids are anteiso-15:0, anteiso-17:0 and iso-15:0. Phylogenetic analysis of 16S rRNA gene sequences revealed that the isolates are closely related to Virgibacillus pantothenticus, Robinsoniella peoriensis, and Bacillus subtilis. Because of their abundance in the deep marine subsurface, these microorganisms likely play an important role in sustaining the deep microbial ecosystem and influencing biogeochemical cycles in the deep biosphere.

    The Iheya North hydrothermal field is located in the middle Okinawa Trough, a young and actively spreading back-arc basin extending behind the Ryukyu arc-trench system in the southeastern margin of the East China Sea. In this hydrothermal field, two scientific drilling expeditions (IODP Exp 331 and SIP CK14-04) were conducted using a deep-sea drilling vessel "Chikyu," and samples from a total of 27 holes were taken. Through these expeditions, Kuroko-type volcanogenic massive sulfide deposits (VMS), hydrothermally altered volcanic rocks, and pumiceous and pelagic sediments were recovered. The recovered core provided important information about the relationship between hydrothermal activity, alteration, and ore mineralization. Whole-rock major element composition and trace element (TE) patterns of pumices were very similar to those of rhyolites in the middle Okinawa Trough (RMO). However, pumices were relatively enriched in chalcophile elements Sr and Nb, which suggest incipient mineralization. Volcanic rock generally demonstrated strong silicification and was greenish pale gray in color. Regardless of severe alteration, some rock displayed major element composition broadly similar to the RMO. Alteration was evidenced by an increase in the content of SiO2 and MgO, and decrease in Al2O3, Na2O, and K2O content. The most striking geochemical feature of altered volcanic rock was the discordance between texture and the degree of modification of TEs. Some samples showed decussate texture occupied by petal-like quartz with severe silicification, but no prominent disturbance of concentration and patterns of TEs were observed. In contrast, samples with well-preserved igneous porphyritic texture showed very low TE content and modification of TE patterns. These results suggest that the modification of texture and composition of TEs, as well as silicification, do not occur by a uniform process, but several processes. This may reflect the differences in temperature and the

    To increase output and meet customers' needs, companies have turned to the development of production management systems: Kaizen, one piece flow, Kanban, etc. The aim of such systems is to accelerate decisions, react to environmental issues and manage various productions. In the main, this type of management system has led to the continuous improvement of production performance. Consequently, such production management systems can have unexpected negative effects on operators' health and safety. Conversely, regulation and control systems focusing on work-related risks have obliged firms to implement health and safety management systems such as OHSAS 18001. The purpose of this type of system, also based on continuous improvement, is to reduce risks, facilitate work-related activities and identify solutions in terms of equipment and tools. However, the prevention actions introduced through health and safety systems often result in other unexpected and unwanted effects on production. This paper shows how companies can improve the way they are run by taking into account both types of management system.

    Process safety practitioners have adopted quality management principles in design of process safety management systems with positive effect, yet achieving safety objectives sometimes remain a distant target. Companies regularly apply tools and methods which have roots in quality and productivity improvement. The "plan, do, check, act" improvement loop, statistical analysis of incidents (non-conformities), and performance trending popularized by Dr. Deming are now commonly used in the context of process safety. Significant advancements in HSE performance are reported after applying methods viewed as fundamental for quality management. In pursuit of continual process safety improvement, the paper examines various quality improvement methods, and explores how methods intended for product quality can be additionally applied to continual improvement of process safety. Methods such as Kaizen, Poke yoke, and TRIZ, while long established for quality improvement, are quite unfamiliar in the process safety arena. These methods are discussed for application in improving both process safety leadership and field work team performance. Practical ways to advance process safety, based on the methods, are given.

    In an effort to improve operational efficiency, healthcare services around the world have adopted process improvement methodologies from the manufacturing sector, such as Lean Production. In this paper we report on four multi-level case studies of the implementation of Lean in the English NHS. Our results show that this generally involves the application of specific Lean 'tools', such as 'kaizen blitz' and 'rapid improvement events', which tend to produce small-scale and localised productivity gains. Although this suggests that Lean might not currently deliver the efficiency improvements desired in policy, the evolution of Lean in the manufacturing sector also reveals this initial focus on the 'tool level'. In moving to a more system-wide approach, however, we identify significant contextual differences between healthcare and manufacturing that result in two critical breaches of the assumptions behind Lean. First, the customer and commissioner in the private sector are the one and the same, which is essential in determining 'customer value' that drives process improvement activities. Second, healthcare is predominantly designed to be capacity-led, and hence there is limited ability to influence demand or make full use of freed-up resources. What is different about this research is that these breaches can be regarded as not being primarily 'professional' in origin but actually more 'organisational' and 'managerial' and, if not addressed could severely constrain Lean's impact on healthcare productivity at the systems level.

    National healthcare systems worldwide face growing challenges to reconcile interests of patients for high-quality medical care and of payers for sustainable and affordable funding. Advances in the provision of renal replacement therapy can only be made by developing and implementing appropriate sophisticated and state-of-the-art business models that include reimbursement schemes for comprehensive care packages. Such business models must succeed in integrating and reconciling the interests of all stakeholders. NephroCare as dialysis provider has adopted and tailored recognized management techniques, i.e. Balanced Scorecard and Kaizen, to achieve these goals. Success of the complete business model package is tangible - strategies initiated to improve treatment quality even at the cost of providers have been translated into win-win scenarios for the complete stakeholder community. Room for improvement exists: the possibility to extend the portfolio of service offerings within the comprehensive care frame, as well as the challenge for achieving a balance between the stability of targets while keeping these up to date concerning new insights.

    Kaizen--a continuously improving--is a philosophy lived in Japan which is also becoming more and more important in Western companies. To implement this philosophy in the semiconductor industry, a high performance metrology tool is essential to determine the status of production quality periodically. An important prerequisite for statistical process control is the high stability of the metrology tool over several months or years; the tool-induced shift should be as small as possible. The pattern placement metrology tool Leitz LMS 2000 has been used in a major European mask house for several years now to qualify masks within the tightest specifications and to monitor the MEBES III and its cassettes. The mask shop's internal specification for the long term repeatability of the pattern placement metrology tool is 19 nm instead of 42 nm as specified by the supplier of the tool. Then the process capability of the LMS 2000 over 18 months is represented by an average cpk value of 2.8 for orthogonality, 5.2 for x-scaling, and 3.0 for y-scaling. The process capability of the MEBES III and its cassettes was improved in the past years. For instance, 100% of the masks produced with a process tolerance of +/- 200 nm are now within this limit.

Employees offered more than 30 suggestions, of which more than a half are being implemented now and further actions are being prepared for implementation. The authors will present the results of improvements in, for example, tool replacement time, scrap reduction. The authors will present how kaizen can improve the production and quality control processes.

    The Ares launch vehicles team, managed by the Ares Projects Office (APO) at NASA Marshall Space Flight Center, has completed the Ares I Crew Launch Vehicle System Requirements Review and System Definition Review and early design work for the Ares V Cargo Launch Vehicle. This paper provides examples of how Lean Manufacturing, Kaizen events, and Six Sigma practices are helping APO deliver a new space transportation capability on time and within budget, while still meeting stringent technical requirements. For example, Lean philosophies have been applied to numerous process definition efforts and existing process improvement activities, including the Ares I-X test flight Certificate of Flight Readiness (CoFR) process, risk management process, and review board organization and processes. Ares executives learned Lean practices firsthand, making the team "smart buyers" during proposal reviews and instilling the team with a sense of what is meant by "value-added" activities. Since the goal of the APO is to field launch vehicles at a reasonable cost and on an ambitious schedule, adopting Lean philosophies and practices will be crucial to the Ares Project's long-term SUCCESS.

There are some problems related to equipment settings for activity involving students such as files which is accumulated over the previous year practicum, as well as the movement of waste in the form of time due to the placement of goods that do not fit. Therefore, this study aims to apply the 5S method in DSK & E laboratory to facilitate the work processes and reduce waste. The project is performed by laboratory management using 5S methods in response to continuous improvement (Kaizen). Moreover, some strategy and suggestions are promoted to impose 5S system within the laboratory. As a result, the tidiness and cleanliness can be achieved that lead to the great performance of laboratory users. Score assessment before implementing 5S DSKE laboratory is at 64 (2.56) while the score after implementation is 32 (1.28) and shows an improvement of 50%. This has implications for better use in the laboratory area, save time when looking for tools and materials due to its location and good visual control, as well as improving the culture and spirit of ‘5S’ on staff regarding better working environment

    A Space Act Agreement (SAA) is a contractual vehicle that NASA utilizes to form partnerships with non-NASA entities to stimulate cutting-edge innovation within the science and technology communities while concurrently supporting the NASA missions. SAAs are similar to traditional contracts in that they involve the commitment of Agency resources but allow more flexibility and are more cost effective to implement than traditional contracts. Consequently, the use of SAAs to develop partnerships has greatly increased over the past several years. To facilitate this influx of SAAs, Marshall Space Flight Center (MSFC) developed a process during a kaizen event to streamline and improve the quality of SAAs developed at the Center level. This study assessed the current SAA process to determine if improvements could be implemented to increase productivity, decrease time to activation, and improve the quality of deliverables. Using a combination of direct procedural observation, personnel interviews, and statistical analysis, elements of the process in need of remediation were identified and potential solutions developed. The findings focus primarily on the difficulties surrounding tracking and enforcing process adherence and communication issues among stakeholders. Potential solutions include utilizing customer relationship management (CRM) software to facilitate process coordination and co-locating or potentially merging the two separate organizations involved in SAA development and activation at MSFC.

    Correctional Officers (COs) have among the highest injury rates and poorest health of all the public safety occupations. The HITEC-2 (Health Improvement Through Employee Control-2) study uses Participatory Action Research (PAR) to design and implement interventions to improve health and safety of COs. HITEC-2 compared two different types of participatory program, a CO-only "Design Team" (DT) and "Kaizen Event Teams" (KET) of COs and supervisors, to determine differences in implementation process and outcomes. The Program Evaluation Rating Sheet (PERS) was developed to document and evaluate program implementation. Both programs yielded successful and unsuccessful interventions, dependent upon team-, facility-, organizational, state-, facilitator-, and intervention-level factors. PAR in corrections, and possibly other sectors, depends upon factors including participation, leadership, continuity and timing, resilience, and financial circumstances. The new PERS instrument may be useful in other sectors to assist in assessing intervention success. Am. J. Ind. Med. 59:897-918, 2016. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Lean Six Sigma methodology is increasingly used to drive improvement in patient safety, quality of care, and cost-effectiveness throughout the US health care delivery system. To demonstrate our value as specialists, radiologists can combine lean methodologies along with imaging expertise to optimize imaging elements-of-care pathways. In this article, we describe a Lean Six Sigma project with the goal of reducing the relative use of pediatric head CTs in our population of patients with hydrocephalus by 50% within 6 months. We applied a Lean Six Sigma methodology using a multidisciplinary team at a quaternary care academic children's center. The existing baseline imaging practice for hydrocephalus was outlined in a Kaizen session, and potential interventions were discussed. An improved radiation-free workflow with ultrafast MR imaging was created. Baseline data were collected for 3 months by using the departmental radiology information system. Data collection continued postintervention and during the control phase (each for 3 months). The percentage of neuroimaging per technique (head CT, head ultrasound, ultrafast brain MR imaging, and routine brain MR imaging) was recorded during each phase. The improved workflow resulted in a 75% relative reduction in the percentage of hydrocephalus imaging performed by CT between the pre- and postintervention/control phases (Z-test, P = .0001). Our lean interventions in the pediatric hydrocephalus care pathway resulted in a significant reduction in head CT orders and increased use of ultrafast brain MR imaging. © 2016 by American Journal of Neuroradiology.

    Apparel exports bring in sizeable foreign income to Sri Lanka. To protect and promote this industry is a paramount need. This can be carried out by applying Human Factors/Ergonomics (HFE) which has proved to control negative effects at work places. This paper reports a case study which describes the demands and benefits of HFE in MAS Holdings which owns a large share of the apparel industry in Sri Lanka. The study consisted of walk through observation survey, a questionnaire survey and ergonomic work place analysis followed by a training programme to selected employees in three companies. Positive responses to questionnaires revealed good ergonomic practices in the work places surveyed. Ergonomically unfit chairs and potential hazards e.g. exposure to noise and hot environment were detected. It is seen that MAS have introduced strategies originated by Toyota Production System viz. 5S, Kaizen, six sigma etc., which are in fact ergonomic methods. A progressive project MAS boast of viz. 'MAS Operating System' (MOS) empowers training and development to employees. MAS Holdings has adequately realized the benefits of applying HFE as evident by the number of awards received. Relevant companies were advised to take appropriate corrective measures to control the potential hazards.

    The application of lean methodology in an initiative to redesign the formulary maintenance process at an academic medical center is described. Maintaining a hospital formulary requires clear communication and coordination among multiple members of the pharmacy department. Using principles of lean methodology, pharmacy department personnel within a multihospital health system launched a multifaceted initiative to optimize formulary management systemwide. The ongoing initiative began with creation of a formulary maintenance redesign committee consisting of pharmacy department personnel with expertise in informatics, automation, purchasing, drug information, and clinical pharmacy services. The committee met regularly and used lean methodology to design a standardized process for management of formulary additions and deletions and changes to medications' formulary status. Through value stream analysis, opportunities for process and performance improvement were identified; staff suggestions on process streamlining were gathered during a series of departmental kaizen events. A standardized template for development and dissemination of monographs associated with formulary additions and status changes was created. In addition, a shared Web-based checklist was developed to facilitate information sharing and timely initiation and completion of tasks involved in formulary status changes, and a permanent formulary maintenance committee was established to monitor and refine the formulary management process. A clearly defined, standardized process within the pharmacy department was developed for tracking necessary steps in enacting formulary changes to encourage safe and efficient workflow.

    Purpose The purpose of this paper is to present findings from a study of factors that affect continuous improvement (CI) project success in hospitals. Design/methodology/approach Quantitative regression analysis was performed on Likert scale survey responses. Qualitative thematic analysis was performed on open-ended survey responses and written reports on CI projects. Findings The paper identifies managerial and employee factors that affect project success. These factors include managerial support, communication, and affective commitment. Affective commitment is the extent to which employees perceive the change as being needed or necessary. Practical implications The results highlight how managerial decisions, approaches to communication - including communication before, during and after CI projects affect project success. The results also show that success depends on the way employees perceive proposed changes. This suggests the need for a more individualized approach to CI, lean, and broader change initiatives. Originality/value This research is the first to fuse project success and sustainability theory to CI projects, beyond Kaizen events, in healthcare environments. The research is particularly important at a time when healthcare organizations are required to make rapid changes with limited resources as they work toward outcome-based assessment and reimbursement rules.

    To implement Lean principles to accommodate expanding volumes of gastrointestinal biopsies and to improve laboratory processes overall. Our continuous improvement (kaizen) project analyzed the current state for gastrointestinal biopsy handling using value-stream mapping for specimens obtained at a 487-bed tertiary care pediatric hospital in Dallas, Texas. We identified non-value-added time within the workflow process, from receipt of the specimen in the histology laboratory to the delivery of slides and paperwork to the pathologist. To eliminate non-value-added steps, we implemented the changes depicted in a revised-state value-stream map. Current-state value-stream mapping identified a total specimen processing time of 507 minutes, of which 358 minutes were non-value-added. This translated to a process cycle efficiency of 29%. Implementation of a revised-state value stream resulted in a total process time reduction to 238 minutes, of which 89 minutes were non-value-added, and an improved process cycle efficiency of 63%. Lean production principles of continuous improvement and waste elimination can be successfully implemented within the clinical laboratory.

    To develop tools offering definite orientation for managers and employees to support their work improvement through occupational mental health. This research was a part of the Mental Health Improvement & Reinforcement Study (MIR study), conducted from October 2004 to March 2006. We developed a trial version named the Kaizen Check List (KCL) by referring to problem solving methods for quality management. Then we improved it for a formal version named MIR Research of Recognition (MIRROR). A feedback form named MIR Action Guidance (MIRAGe) was also developed. We analyzed data from 1,953 respondents at five manufacturing enterprises in Japan using MIRROR and the Brief Job Stress Questionnaire (BJSQ) to determine whether or not the workers requesting work improvement had more stress than other workers. The KCL had 47 items, which indicated desirable working conditions for mental health at work, and four answer categories. MIRROR has 45 selected items and improved answer categories. MIRAGe displays the results of MIRROR and step-by-step guidance for work improvement. Respondents with request had significantly higher scores in stressor and lower scores in buffer factors compared with respondents without request in many items of MIRROR. A combinational use of MIRROR and stress scales is useful for finding worksites with high risk factors for mental health and for directing focus on work improvement at these worksites according to workers' requests.

    Japan is well known as a super-aging society, with a low birth rate, and has been ranked as one of the countries having the highest quality of healthcare system. Japan's society is currently approaching a major turning point with regard to societal and healthcare reforms, which are influenced by international trends and regional needs. Development of Japanese healthcare human resources, including medical students, is now expected to ride the wave of globalization, while resolving regional problems in the training and delivery of healthcare. Terms and global trends in medical education, such as outcome-based education, community-based education, reflective learning, international accreditation of medical education, and professionalization of educators are well translated into the Japanese language and embraced positively among the Japanese medical educators. However, these trends occasionally sit uncomfortably with cultural variations that are often a common approach in Japan; notably, "hansei" (introspection) and "kaizen" (change for the better). In the world facing a new era where people are unsettled between globalism and regionalism, Japan's future mission is to steer a balanced route that recognizes both global and regional influences and produce global health professionals educators.

    The proponents of lean production have pointed to the positive effects of the work organization on employees in terms of autonomy, enhanced skills and empowerment mainly by their participation into the continuous improvement of work process. But studies that have examined this issue suggest that the increase in autonomy is not sufficient to compensate for increases work intensity. Participatory design has grown extensively in manufacturing since the 1980's under the impulsion of the Scandinavian socio-technical system approach and it's central in the model of lean production performance. Its main objectives are to improve quality, increase productivity and safety through employee's participation to the reduction of non-value added activities, such as defined by lean production. In the line of the studies on participatory design and continuous improvement the present study examines the functioning of work groups, based on the kaizen model, the aim of which was to improve the proportion of "value-added activities" and working conditions, essentially physical constraints. The main results are consistent with the literature and show that accelerated forms of re-conception activities give employees limited room for maneuver to elaborate solutions based on the analysis of the real activity. This study is part of a broader initiative that goes in the direction of continuous improvement of the design process itself so that it integrates the real constraints of work and propose changes bases on work as it actually takes place, beyond pre-established performance goals bases on the reduction of "non added value activities".

    Deep subseafloor environments associated with hydrocarbon reservoirs have been least explored by previous scientific drilling and hence the nature of deep subseafloor life and its ecological roles in the carbon cycle remain largely unknown. In this study, we performed cultivation of subseafloor methanogenic communities using a continuous-flow bioreactor with polyurethane sponges, called down-flow hanging sponge (DHS) reactor. The sample used for the reactor cultivation was obtained from 2 km-deep coalbeds off the Shimokita Peninsula of Japan, the northwestern Pacific, during the Integrated Ocean Drilling Program (IODP) Expedition 337 using a riser drilling technology of the drilling vessel Chikyu. The coalbed samples were incubated anaerobically in the DHS reactor at the in-situ temperature of 40°C. Synthetic seawater supplemented with a tiny amount of yeast extract, acetate, propionate and butyrate was provided into the DHS reactor. After 34 days of the bioreactor operation, a small production of methane was observed. The methane concentration was gradually increased and the stable carbon isotopic composition of methane was consistency 13C-depleted during the bioreactor operation, indicating the occurrence of microbial methanogenesis. Microscopic observation showed that the enrichment culture contained a variety of microorganisms, including methanogen-like rod-shaped cells with F420 auto-fluorescence. Interestingly, many spore-like particles were observed in the bioreactor enrichment. Phylogenetic analysis of 16S rRNA genes showed the growth of phylogenetically diverse bacteria and archaea in the DHS reactor. Predominant archaeal components were closely related to hydrogenotrophic methanogens within the genus Methanobacterium. Some predominant bacteria were related to the spore-formers within the class Clostridia, which are overall in good agreement with microscopic observations. By analyzing ion images using a nano-scale secondary ion mass spectrometry (Nano

    2015-12-01

    During the Integrated Ocean Drilling Program (IODP) Expedition 337 in 2012, the riser-drilling vessel Chikyu extended the previous world depth record of scientific ocean drilling and made one of the deepest scientific borehole down to 2466 m below the seafloor (mbsf) at Site C0020 Hole A off the Shimokita Peninsula, Japan. The sedimentary sequence consists of 17 lignite layers below 1.5 km bellow the seafloor. Microbiological and geochemical data consistently showed evidence for the existence of microbial communities associated with lignite coal beds in the coal-bearing sediments (Inagaki and Hinrichs et al., Science, 2015). Since lignite coals produce substantial dissolved organic compounds during the burial alternation process, volatile fatty acids may play important roles for microbial life and its activity in the deep sedimentary environment. To address this hypothesis, we measured methanogenic and acetate-oxidation activities by radiotracer incubation experiments using 14C-labelled substrate ([2-14C]-acetate) immediately after core recovery. Activity of aceticlastic methanogenesis was observed in the sediment above the coal-baring layers (>1990 mbsf), ranging from 0.2 to 1.2 pmol cm-3 d-1. The highest activity was observed in a coal-bed horizon at 1990 mbsf. However, aceticlastic methanogenesis was below the detection limit in sediment samples below the 2 km-coal layers. Activity of acetate oxidation to CO2 was measured by 14CO2 production rate from [2-14C]-acetate. Interestingly, the acetate-oxidation activity was observed in sediments above the coal beds, which values were generally higher than those of methanogenesis with the maximum value of 33 pmol cm-3 d-1 at 1800 mbsf. The rates gradually decreased with increasing depth from 1800 mbsf and reached below the detection limit (i.e., 0.05 pmol cm-3 d-1) in 2 km-deep coal-bed samples. The occurrence of relatively high acetate oxidation at ~1800 mbsf above the coal formation suggests that microbes respire

    In recent years the Gulf of Lion within the western Mediterranean Sea has become a unique natural laboratory to study both the evolution and interaction of deep processes (geodynamics, tectonics, subsidence, isostasy) and surficial processes (river behavior, sedimentary fluxes, sea-level changes, climatic impacts). We present the three main objectives for the GOLD deep drilling project at the foot of the continental slope (2400 m water depth) in the Gulf of Lion, the only place where the complete high-resolution history of the last 30 Ma of Mediterranean history is recorded in some 7.7 km of sedimentary archive 1) For the substratum: the upper continental crust thins to less than 5 km, and changes laterally to a relatively thin crust with high velocities whose precise nature is still undetermined (Gailler et al., 2009). The aim of the drilling is to reach this crucial zone, which is essential for the understanding of margin formation and the evolution of sedimentary basin (Aslanian et al., 2009). 2) The drilling will allow the dating and characterization of the impact of climate variations on sedimentation in the deep basin. For the Miocene and older sediments the drilling, will yield information about the nature, paleoenvironments and age of deposits enabling an astronomically-tuned Neogene time scale to be refined for the period of Aquitanian through Langhian interval. The Messinian extreme event represents a unique crisis in Earth history. It is a unique case to study the impact of sea-level drop (more than 1000 m, one order of magnitude greater than Late Quaternary glaciations) on sedimentary river behavior, deltaic and evaporitic deposition and ensuing biotic crisis. Deep drilling with the R/V Chikyu is the only way to go through the complete series of evaporites in the Provence Basin, sample the initiation and evolution of the crises, the first deposits related to the lowering of sea-level on the one hand and to the salinity crisis on the other. 3) The

    Integrated Ocean Drilling Program Expedition 338 was the second scientific expedition with D/V Chikyu during which riser drilling was conducted as part of the Nankai Trough Seismogenic Zone Experiment. Riser drilling enabled sampling and real-time monitoring of drilling mud gas with an onboard scientific drilling mud gas monitoring system ("SciGas"). A second, independent system was provided by Geoservices, a commercial mud logging service. Both systems allowed the determination of (non-) hydrocarbon gas, while the SciGas system also monitored the methane carbon isotope ratio (δ(13)CCH4). The hydrocarbon gas composition was predominated by methane (> 1%), while ethane and propane were up to two orders of magnitude lower. δ(13)CCH4 values suggested an onset of thermogenic gas not earlier than 1600 meter below seafloor. This study aims on evaluating the onboard data and subsequent geological interpretations by conducting shorebased analyses of drilling mud gas samples. During shipboard monitoring of drilling mud gas the SciGas and Geoservices systems recorded up to 8.64% and 16.4% methane, respectively. Ethane and propane concentrations reached up to 0.03 and 0.013%, respectively, in the SciGas system, but 0.09% and 0.23% in the Geoservices data. Shorebased analyses of discrete samples by gas chromatography showed a gas composition with ~0.01 to 1.04% methane, 2 - 18 ppmv ethane, and 2 - 4 ppmv propane. Quadruple mass spectrometry yielded similar results for methane (0.04 to 4.98%). With δD values between -171‰ and -164‰, the stable hydrogen isotopic composition of methane showed little downhole variability. Although the two independent mud gas monitoring systems and shorebased analysis of discrete gas sample yielded different absolute concentrations they all agree well with respect to downhole variations of hydrocarbon gases. The data point to predominantly biogenic methane sources but suggest some contribution from thermogenic sources at depth, probably due

    The microbial populations and the limit of microbial life are probably limited by chemical, physical, and geological conditions, such as temperature, pore water chemistry, pH, and water activity; however, the key parameters affecting growth in deep subseafloor sediments remain unclarified (Hinrichs and Inagaki 2012). IODP expedition 337 was conducted near a continental margin basin off Shimokita Peninsula, Japan to investigate the microbial activity under deep marine coalbed sediments down to 2500 mbsf. Inagaki et al. (2015) discovered that microbial abundance decreased markedly with depth (the lowest cell density of <1 cell/cm3 was recorded below 2000 mbsf), and that the coal bed layers had relatively higher cell densities. In this study, permeability was measured on core samples from IODP Expedition 337 and Expedition CK06-06 in the D/V Chikyu shakedown cruise. Permeability was measured at in-situ effective pressure condition. Permeability was calculated by the steady state flow method by keeping differential pore pressure from 0.1 to 0.8 MPa.Our results show that the permeability for core samples decreases with depth from 10-16 m2 on the seafloor to 10-20 m2 at the bottom of hole. However, permeability is highly scattered within the coal bed unit (1900 to 2000 mbsf). Permeabilities for sandstone and coal is higher than those for siltstone and shale, therefore the scatter of the permeabilities at the same unit is due to the high variation of lithology. The highest permeability was observed in coal samples and this is probably due to formation of micro cracks (cleats). Permeability estimated from the NMR logging using the empirical parameters is around two orders of magnitude higher than permeability of core samples, even though the relative permeability variation at vertical direction is quite similar between core and logging data.The higher cell density is observed in the relatively permeable formation. On the other hand, the correlation between cell density

    International Ocean Discovery Program (IODP) Expedition 348, the latest advance of the NanTroSEIZE project, started on 13 September 2013 and was completed on 29 January 2014. During Expedition 348, the drilling vessel Chikyu advanced the ultra-deep riser hole at Site C0002, located 80 km offshore of the Kii Peninsula, from a depth of 860 meters below sea floor (mbsf) to 3058.5 mbsf, the world record for the deepest scientific ocean drilling, and cased it for future deepening. The drilling operation successfully obtained data on formation physical properties from logging while drilling (LWD) tools, as well as from lithological analyses of cuttings and core from the interior of the active accretionary prism at the Nankai Trough. IODP Site C0002 is the currently only borehole to access the deep interior of an active convergent margin. Preliminary scientific results of Expedition 348 are as follows: (1) Fine-grained turbiditic mudstones with coarser silty and sandy interbeds, exhibiting steep dips (between ~60 and 90 degrees) are predominant in the prism down to ~3000 mbsf. The biostratigraphic age of the sediments in the lowermost part of the hole is thought to be 9-11 Ma, with an assumed age of accretion of 3-5 Ma. (2) Slickenlined surfaces, deformation bands and mineral veins are present throughout the drilled interval, while well-developed scaly clay fabrics are increasingly observed below ~2200 mbsf. A substantial fault zone with well-developed foliation was successfully cored from the deep interior of the prism at ~2205 mbsf. (3) Porosity generally decreases from ~60% to ~20% from the seafloor to 3000 mbsf. However, physical properties including grain density, electrical conductivity and P-wave velocity suggest fairly homogeneous properties in the interior of the prism between ~2000 and 3000 mbsf. (4) Mud gas analysis during the riser drilling indicates that a source of methane gas shifts from microbial origin to thermogenic at around 2325 mbsf. (5) The maximum

    Since the first deep biosphere-dedicated Ocean Drilling Program (ODP) Leg 201 using the US drill ship JOIDES Resolution in 2002, scientific ocean drilling has offered unique opportunities to expand our knowledge of the nature and extent of the deep biosphere. The latest estimate of the global subseafloor microbial biomass is ~1029cells, accounting for 4 Gt of carbon and ~1% of the Earth's total living biomass. The subseafloor microbial communities are evolutionarily diverse and their metabolic rates are extraordinarily slow. Nevertheless, accumulating activity most likely plays a significant role in elemental cycles over geological time. In 2010, during Integrated Ocean Drilling Program (IODP) Expedition 329, the JOIDES Resolutionexplored the deep biosphere in the open-ocean South Pacific Gyre—the largest oligotrophic province on our planet. During Expedition 329, relatively high concentrations of dissolved oxygen and significantly low biomass of microbial populations were observed in the entire sediment column, indicating that (i) there is no limit to life in open-ocean sediment and (ii) a significant amount of oxygen reaches through the sediment to the upper oceanic crust. This "deep aerobic biosphere" inhabits the sediment throughout up to ~37 percent of the world's oceans. The remaining ~63 percent of the oceans is comprised of higher productivity areas that contain the "deep anaerobic biosphere". In 2012, during IODP Expedition 337, the Japanese drill ship Chikyu explored coal-bearing sediments down to 2,466 meters below the seafloor off the Shimokita Peninsula, Japan. Geochemical and microbiological analyses consistently showed the occurrence of methane-producing communities associated with the coal beds. Cell concentrations in deep sediments were notably lower than those expected from the global regression line, implying that the bottom of the deep biosphere is approached in these beds. Taxonomic composition of the deep coal-bearing communities profoundly

    IODP Expedition 343, Japan Trench Fast Drilling Project (JFAST), drilled across the plate-boundary décollement zone near the Japan Trench where large slip occurred during the March 2011 Tohoku-oki earthquake. We conducted paleomagnetic measurements of the core sample retrieved from the highly-deformed sediments comprising the plate-boundary décollement zone. Whole-round samples for structural analyses from five depth intervals of the core (0-12 cm, 12-30 cm, 43-48 cm, 48-58 cm, and 87.5-105 cm), were trimmed into oriented slabs with typical dimensions of 3x3x5 cm that are now being used to make petrographic sections for microstructural and chemical study. The remainder of the core sample was split into working and archive halves. We measured remanent magnetization of 16 trimmed slabs and the archive half of the core sample. The slabs were subjected to natural remanent magnetization (NRM) measurements in 0.5-1 cm intervals and progressive alternating field demagnetization (AFD) up to 80 mT with a 2G755 pass-through superconducting rock magnetometer at Kochi University. The archive half of the core sample was subjected to NRM measurement and AFD up to 20 mT with a 2G760 superconducting rock magnetometer installed on R/V Chikyu. Typically, two or three paleomagnetic components were isolated during the AFD of slab samples up to 80 mT. One ';soft' component was demagnetized below 20-30 mT, and another ';hard' component was not demagnetized even with AFD in 80 mT. A third component may be separated during AFD at the intermediate demagnetizing field, and may overlap the soft and hard components. The multiple slab samples cut from an identical whole-round sample have generally consistent paleomagnetic direction of the hard component. Contrastingly, the direction of the soft component is less consistent between adjacent slabs, and even varies within a single slab. The direction variation of the soft component possibly reflects the cm-scale strain and rotation of the

    Scientific ocean drilling has traditionally been conducted within a framework of international programmes. The current phase, IODP (Integrated Ocean Drilling Program), started in 2004. As opposed to its predecessors, IODP has a multiplatform approach allowing to encompass most oceanic environments and therefore expands the scientific opportunities. USA operates the non-riser vessel JOIDES Resolution. Japan operates the Chikyu, a vessel specially built for scientific purposes and equipped with a riser system that allows drilling in unstable formation and down to ~6 km beneath the seafloor. The creation of ECORD (European Consortium for Ocean Research Drilling), consortium of 16 (now 17) European countries and Canada that joined IODP as a single member, made possible the development of the concept of Mission Specific Platforms (MSPs). MSPs are platforms of opportunity contracted on a case by case basis that have allowed scientific ocean drilling to recover cores from ice-covered and shallow water targets that are generally inaccessible to the two dedicated IODP platforms. The current phase of IODP is ending in September 2013 and the new phase of ocean drilling is being prepared. A new science plan, elaborated by the international science community, was released in June 2011: http://www.iodp.org/Science-Plan-for-2013-2023/. The three current major players (USA, Japan and ECORD) are willing to participate in the next phase and continue providing access to all three platforms, although final funding decisions are still pending at the national level. The new organizational framework for scientific ocean drilling will be streamlined for a more efficient proposal review system and a better use of resources. An international evaluation for drilling proposals will be maintained, but the platforms will be operated independently by the country/consortia providing them. At the ECORD level, the new organisation may secure more funding for MSP operations and the goal is to

    IODP Expedition 350 Site U1436C lies in the western part of the Izu fore arc basin, ~60 km east of the arc front volcano Aogashima, at 1776 m water depth. This site is a technical hole (only a 150 m long record) for a potential future deep drilling by Chikyu. Site U1437 is located in the Izu rear arc, ~90 km west of the arc front volcanoes Myojinsho and Myojin Knoll, at 2117 m water depth. At this site in order to study the evolution of the IZU rear arc crust we recovered a 1800 meter long sequence of mud and volcaniclastic sediments. These sites provide a rich and well-preserved record of volcanic eruptions within the area of the Izu Bonin-Arc. However, the material recovered, mostly mud with ash containing generally abundant planktonic foraminifera, can support additional paleoceanographic goals in an area affected by the Kuroshio Current. Also, the hydrographic divide created by the Izu rise provides a rare opportunity to gain some insight into the operation of the global intermediate circulation. The Antarctic Intermediate Water Mass is more influential at the depth of U1437B in the West and the North Pacific Intermediate Water at Site U1436C to the East. We analyzed 460 samples recovered at Sites U1436C and U1437B for a quantitative planktonic foraminifer study, and also for carbonate preservation indices, including: shell weight, percent planktonic foraminifera fragments planktonic foraminifer concentrations, various faunal proxies, and benthic/planktonic ratio. We measured the stable isotopes for a similar number of samples using the thermocline dwelling Neogloboquadrina dutertrei. The dataset presented here covers the last 1 Ma at Site U1437B and 0.9 Ma at Site U1436C. The age models for the two sites are largely established through stable isotope stratigraphy (this study). On their respective age models we evidence based on polar/subpolar versus subtropical faunal assemblages changes qualitative surface water temperature variations recording the changing

    Within the Integrated Ocean Drilling Program (IODP), ECORD-operated Mission Specific Platforms (MSPs) have allowed scientific ocean drilling to recover core from targets that are generally inaccessible to the two dedicated IODP platforms: the US-operated JOIDES Resolution and the Japanese-operated Chikyu. By contracting vessels, drilling and logging services on a case-by-case basis, IODP has used MSPs to successfully conduct expeditions in the high Arctic Ocean and around Tahiti, and has shown that the program can recover cores in ice-covered waters and in very shallow water. The key strength of the MSP approach is that vessels, drilling and logging systems can be contracted to meet the particular needs of a scientific proposal. Within IODP, MSPs carry the necessary staff and equipment to recover and curate the core, to carry out initial descriptions, undertake a tailored downhole logging program and conduct essential measurements of physical and ephemeral properties. Comprehensive description and analysis of the cores to IODP standards takes place after the offshore phase has ended at the IODP Bremen Core Repository (BCR) in Germany. Depending on availability and cost, potentially any vessel, drilling or logging system can be hired to conduct an MSP. Future possibilities may include the Aurora Borealis that is currently being planned as an ice-breaking drilling vessel with the capability to penetrate 1000 m in 5000 m of water. The concept of MSPs could also be widened beyond vessels with conventional drill rigs. New and alternative technologies can be contracted as part of an MSP Expedition, for example remotely-operated shallow rock drills like MeBo (developed by the MARUM - Center for Marine Environmental Sciences) and the BGS Rockdrills (developed by the British Geological Survey). Such technologies have many advantages: they can be quickly deployed from a range of research and industry vessels, they can operate in a wide range of water depths (up to 6000 m by

    Mission Specific Platform (MSP) expeditions are operated by the European Consortium for Ocean Research Drilling (ECORD). Each MSP expedition is unique within the Integrated Ocean Drilling Program (IODP). In order to complement the abilities of the JOIDES Resolution and the Chikyu, the ECORD Science Operator (ESO) must source vessels and technology suitable for each MSP proposal on a case-by-case basis. The result is that ESO can meet scientific requirements in a flexible manner, whilst maintaining the measurements required for the IODP legacy programme. The process of tendering within EU journals for vessels and technology means that the planning process for each MSP Expedition starts many years in advance of the operational phase. Involvement of proposal proponents from this early stage often leads to the recognition for technological research and development to best meet the scientific aims and objectives. One example of this is the planning for the Atlantis Massif proposal, with collaborative development between the British Geological Survey (BGS) and MARUM, University of Bremen, on suitable instruments for seabed drills, with the European Petrophysics Consortium (EPC) driving the development of suitable wireline logging tools that can be used in association with such seabed systems. Other technological developments being undertaken within the European IODP community include in-situ pressure sampling for gas hydrate expeditions, deep biosphere and fluid sampling equipment and CORK technology. This multi-national collaborative approach is also employed by ESO in the operational phase. IODP Expedition 302 ACEX saw vessel and ice management support from Russia and Sweden to facilitate the first drilling undertaken in Arctic sea ice. A review of MSP expeditions past, present and future reveal the significant impact of European led operations and scientific research within the current IODP programme, and also looking forward to the start of the new International

    A scientific drilling expedition was conducted at an active hydrothermal field on the Iheya-North Knoll by D/V Chikyu in 2014 (Expedition 907) as a part of "Next-generation Technology for Ocean Resources Survey" of the Cross-ministerial Strategic Innovation Promotion Program. During the expedition logging while drilling (LWD) was deployed to constrain the area of the fluid reservoir beneath seafloor followed by three coring holes down to 150 meter below the seafloor (mbsf). The LWD system is composed of arcVISION for resistivity and natural gamma ray measurement and TeleScope for real-time transmission of drilling parameters and arcVISION data. Five sites (C9011-15) at the Iheya-North Original Site and one site (C9016) at Aki Site were drilled with LWD. At C9012 and C9016, the arcVISION detected temperature anomaly up to 84℃ at 234 mbsf and up to 39℃ at 80 mbsf, respectively. The temperature quickly increases at that depth and it would reflect the existence of high-temperature heat source along borehole. Due to the continuous fluid circulation during drilling, the measured temperature does not indicate in-situ temperature, but it reflects the heat disturbed by the cold circulated water instead. High quality resistivity and natural gamma ray data were acquired at six sites. The log curves at Site C9016 show characteristic response; the natural gamma ray log exhibits extremely high radiation (>500 gAPI) at 7-13 and 23-31 mbsf (Zone A). In the underlying interval of 31-40 mbsf, the resistivity log exhibits extremely low value (<0.2 ohm-m) (Zone B). Then the resistivity log exhibits higher value (~10 ohm-m) and the natural gamma ray log shows very low radiation (<50 gAPI) at the interval of 41-48 mbsf (Zone C). The log characteristics in Zone A, B, and C can be interpreted as a series of K-rich alteration zone, sulfide zone, and low-K hard (silicified) sediments, respectively. The LWD-based lithological interpretation was confirmed by the following core description

    The drilling vessel Chikyu completed the first riser-drilling in IODP history to a depth of 1603 mbsf (meter below seafloor) at Site C0009 in the landward Kumano forearc basin in the Nankai convergent margin, Japan.To measure in situ stress we performed two types of hydraulic fracturing: 1) as part of routine drilling operations, we estimated least principle stress from a leak off test (LOT); and 2) we used Schlumberger’s dual wireline packer, the Modular Dynamics Tester (MDT). Two LOT’s were performed at the base of 20 inch casing (703.9 mbsf) as a part of standard drilling operations; the outer annulus was closed by the blowout preventor (BOP), fluid was pumped at a constant rate of 2.3 m3/s, and pressure was measured at the cement pumps. The leak-off pressures were interpreted to lie at the break in slope in a graph of pressure vs volume-pumped. These values were found to be 30.22 and 30.25 MPa. These leak off pressure is interpreted to record fluids entering hydraulic fractures and is approximately the the least principal stress. There is considerable uncertainty in picking the slopes of the lines to determine the least principal stress (S3). The MDT dual packer tests were carried out at depth of 873.7 and 1532.7 mbsf. The dual packer module isolates a 1-m section of the borehole for testing. Zones free from pre-existing fractures and with near circular hole shape were chosen for the stress measurements. In the HF test at 873.7 m, the pressure cycle was repeated 5 times maintaining flow rate of 20 cm3/s. Periods of each cycles were 80-300 s. We determined the instantaneous shut in pressure to be 34.8 MPa. In the test at 1532.7 m, only one pressure cycle with a flow rate of 20 cm3/s was maintained, which yielded an instantaneous shut in pressure of 41.6 MPa. We interpret the shut-in pressure to record the least principal stress (S3). We do not know the orientation of fractures which were induced or activated by hydraulic fracturing, because no borehole

    The main goal of IODP Expedition 337 was the identification and characterization of the deep coal bed biosphere and hydrocarbon system off the Shimokita Peninsula (Japan) in the northwestern Pacific using the D/V Chikyu. To accomplish this scientific objective, it was also necessary to investigate the inorganic biogeochemistry in order to identify possible electron acceptors and bio-essential nutrients. These biogeochemical parameters greatly influence both, the composition and abundance of microbial communities as well as the organic carbon cycle. In turn, the microbially mediated carbon cycle influences the diagenetic reactions in the subsurface, thus, altering geochemical and physical characteristics of the material. Here we present results from metal and sulfur geochemical analyses from the deep-subsurface sediments (about 1250 to 2466 mbsf) at Site C0020 off Shimokita. The measured concentrations of acid volatile sulfur (AVS) as well as chromium reducible sulfur (CRS) reflect the alteration of iron oxides to iron sulfides and indicate that the main sulfur-bearing phase in the investigated sediments is pyrite. Concentrations of intermediate sulfur species are minor and occur mainly in the coal-bearing interval. Our data show that the uppermost sediments contain higher amounts of pyrite (up to 1.2 wt.%) with an average of 0.5 wt.% compared to the deeper deposits (below about 1800 mbsf), which show an average of 0.16 wt.%. In contrast, iron oxide concentrations are highest in the deeper sediment sections (up to 0.4%), where pyrite concentrations are low. The alteration of iron oxides to sulfides in theses lower section was probably governed by the amount of available sulfide in the pore water. The occurrence of (bio-)reactive iron phases in these deeply buried sediments has implications for the deep biosphere as those minerals have the potential to serve as electron acceptors during burial, including reactions involving deep sourced electron donors, such as

    During the International Ocean Discovery Program (IODP) Expedition 348, which is part of the Nankai Trough Seismogenic Zone Experiment (stage 3), the drilling vessel Chikyu advanced the deep riser hole at Site C0002, located 80 km offshore of the Kii Peninsula (Japan), from a depth of 860 meters below sea floor (mbsf) to 3058.5 mbsf. Underlying the Kumano Basin sediments, the Nankai accretionary prism appears, below 975.5 mbsf. It accreted during Upper Miocene to Pliocene times and is formed mainly by turbiditic silty claystone with rarely observed sandstone intercalations. Cuttings from both the 1-4 mm and >4 mm size fractions were investigated, showing slickenlined surfaces and deformation bands together with carbonate veins throughout the entire section from 1045.5 until 3058.5 mbsf. A scaly fabric is increasingly observed below approximately 2400 mbsf. Clay-rich cuttings were selected at different depth for specific SEM-EDS analysis, in order to investigate the initiation and development of the slickenlined surfaces, from both a structural and mineralogical point of view. Two end-members of the slickenlined surface types were observed: a) isolated smooth and uniform planes, between 20 and 50 μm long, formed by single grains of smectite with marked lineations and frequently jagged boundaries and b) microfaults (longer than 100 μm) with sharp boundaries to the undeformed rock, formed by aggregates of illite and smectite and with a well-developed lineation. In transition between these two end-member types, planes that are apparently unconnected draw a single plane and show subparallel lineations. Concerning the orientation of the slickenlines, it seems to be coherent with that observed in an array of conjugated faults, i.e. all the slickenlines belong to the same plane, in turn sub-perpendicular to the intersection of conjugated planes. These observations suggest that the slickenlined surfaces initiated along single grains of smectite and that with increasing

    Turbidite sediments around the production test site at Daini-Atsumi knoll were deposited under channel and lobe environments of a submarine fan. Changes in physical properties of the sediments are likely caused by differences in the depositional environments. In addition, methane hydrate (MH) crystals growing among sediment grains alter the sediment's original physical properties. Thus, distinguishing between hydrate-bearing sediment and hydrate-free sediment based only on physical property changes measured during downhole logging can be difficult. To more precisely analyze sediment properties, core samples of MH-bearing sediments were taken at the first offshore MH production test site. Samples were collected using a wireline hybrid pressure coring system (Hybrid PCS), which retains downhole pressure, thereby preventing dissociation of MH in the sampled cores. Nondestructive, high-pressure analyses were conducted in both the 2012 summer drilling campaign and a 2013 winter laboratory study in Sapporo. To handle Hybrid PCS cores during the pressure coring campaign in the summer of 2012, a pressure core analysis and transfer system (PCATS) was installed on the research vessel Chikyu (Yamamoto et al., 2012). PCATS P-wave velocity measurements were made at in situ water pressure without causing any core destruction or MH dissociation. In January 2013, Georgia Tech (GT), USGS, AIST, and JOGMEC researchers used pressure core characterization tools (PCCTs) developed by GT to re-measure the P-wave velocity of the MH-bearing sediments at high pressure and low, non-freezing temperature. In the PCATS analysis, results showed a difference of more than 1,200 m/s in P-wave velocities between the MH-bearing sandy and muddy layers. This difference in P-wave velocities was confirmed by PCCTs measurements. P-wave velocities within the turbidite interval tend to decrease upward with the textural grading of the turbidite. Our result implies that MH concentration, which is related to

    The vertical (downward) component of the atmospheric electric field, or potential gradient (PG) under cloud generally reflects the electric charge distribution in the cloud. The PG data at Kakioka, 150 km southwest of the Fukushima Dai-ichi Nuclear Power Plant (FNPP1) suggested that this relation can be modified when the radioactive dust was floating in the air, and the exact relation between the weather and this modification could lead to new insight in plasma physics in the wet atmosphere. Unfortunately the detailed weather data was not available above Kakioka (only the precipitation data was available). Therefore, estimation of the cloud condition during March 2011 was strongly needed. We have developed various meteorological information links (http://www.chikyu.ac.jp/akiyo/firis/) and original radar and precipitation data will be released from the page. Here we present various radar images that we have prepared for March 2011. We prepared three-dimensional radar reflectivity of the C-band radar of JMA in every 10 minutes over all Kanto Plain centered at Tokyo and Fukushima prefecture centered at Sendai. We have released images of each altitude (1km interval) for 15th - 16thand 21th March (http://sc-web.nict.go.jp/fukushima/). The vertical structure of the rainfall is almost the same at 4km with the surface and sporadic high precipitation is observed at 6 km height for 15-16th. While, generally precipitation pattern that is similar to the surface is observed at 5km height on 21th. On the other hand, an X-band radar centered at Fukushima university is also used to know more localized raindrop patterns at zenith angle of 4 degree. We prepared 10-minutes/120m mesh precipitation patterns for March 15th, 16th, 17th, 18th, 20th, 21th, 22th and 23th. Quantitative estimate is difficult from this X-band radar, but localized structure, especially for the rain-band along Nakadori (middle valley in Fukushima prefecture), that is considered to determine the highly

    During IODP Expedition 319, the first riser-drilling borehole in ocean was penetrated by D/V CHIKYU at Site C0009 in the Nankai convergent margin, Japan. From 0 mbsf (meters below seafloor) to 1285 mbsf, the borehole crossed the Kumano forearc basin and from 1285 mbsf to the bottom depth of 1604 mbsf, the Nankai accretionary prism. In a short depth range of 84.20 m from 1509.7 to 1593.9 mbsf, core samples were retrieved by rotary core barrel drilling. We collected 3 whole-round core samples for measurements of anelastic strain recovery (ASR) by the same methods of sample preparation and anelastic strain data acquisition conducted in the previous Stage-1 expeditions of the same NanTroSEIZE drilling program (Byrne et al., 2009; GRL, Vol.36, L23310). Anelastic normal strains, measured every ten minutes in nine directions, including six independent directions, were used to calculate the anelastic strain tensors. All three samples showed coherent strain recovery over a long period more than 1 month. The three samples were from C0009A (3R,1531 mbsf; 4R, 1540 mbsf and 8R, 1577 mbsf, respectively) in lithologic Unit IV interpreted as accretionary prism or deformed slope sediments. All samples are composed of silty clays or hemipelagic muds with relatively high porosities (30%~). The ASR measurement results in Kumano Forearc Basin obtained from C0002 (Byrne et al., 2009) showed the maximum stress orientation is nearly vertical and a normal stress regime. However, the ASR results in the accretionary prism from C0009 show that the maximum principal stress axes plunge gently or are nearly horizontal and the stress regimes appear to be strike-slip or thrust (reverse fault) types. The maximum horizontal principal stress orientaions obtained from the ASR tests also show very good consistency with the stress orientaions determined from borehole breakouts in the same borehole and the same depth range (Lin et al., 2010; GRL, Vol.37, L13303). These results suggest that three

    The history of scientific ocean drilling has developed some new techniques and technologies for drilling science, dynamic positioning being one of the most famous. However, while industry has developed newer tools and techniques, only some of these have been used in scientific ocean drilling. The introduction of riser-drilling, which recirculates the drilling mud and returns to the platform solids and gases from the formation, to the International Ocean Drilling Program (IODP) through the launch of the Japan Agency of Marine Earth-Science and Technology (JAMSTEC) riser-drilling vessel D/V Chikyu, has made some of these techniques available to science. IODP Expedition 319 (NanTroSEIZE Stage 2: riser/riserless observatory) was the first such attempt, and among the tools and techniques used was drilling mud gas analysis. While industry regularly conducts drilling mud gas logging for safety concerns and reservoir evaluation, science is more interested in other components (e.g He, 222Rn) that are beyond the scope of typical mud logging services. Drilling mud gas logging simply examines the gases released into the drilling mud as part of the drilling process; the bit breaks and grinds the formation, releasing any trapped gases. These then circulate within the "closed circuit" mud-flow back to the drilling rig, where a degasser extracts these gases and passes them on to a dedicated mud gas logging unit. The unit contains gas chromatographs, mass spectrometers, spectral analyzers, radon gas analyzers, and a methane carbon isotope analyzer. Data are collected and stored in a database, together with several drilling parameters (rate of penetration, mud density, etc.). This initial attempt was further refined during IODP Expeditions 337 (Deep Coalbed Biosphere off Shimokita), 338 (NanTroSEIZE Stage 3: NanTroSEIZE Plate Boundary Deep Riser 2) and finally 348 (NanTroSEIZE Stage 3: NanTroSEIZE Plate Boundary Deep Riser 3).

    Access to musculoskeletal consultation in the emergency department (ED) is a nationwide problem. In addition, consultation from a subspecialist may be delayed or may not be available, which can slow down the ED flow and reduce patient satisfaction. The purpose of this study was to review the 1-year results of a change in the authors' institutional practice to reduce subspecialty consultation for select musculoskeletal problems while still ensuring adequate patient follow-up in orthopedic or plastic surgery clinics for patients not seen by these services in the ED. The authors hypothesized that select injuries could be safely managed in the ED by using an electronic system to ensure appropriate follow-up care. Using Kaizen methodology, a multidisciplinary group (including ED staff, orthopedics, plastic surgery, pediatrics, nursing, radiology, therapy, and administration) met to improve care for select musculoskeletal injuries. A system was agreed on in which ED providers managed select musculoskeletal injuries without subspecialist consultation. Follow-up was organized using an electronic system, which facilitated communication between the ED staff and the secretarial staff of the subspecialist departments. Over a 1-year period, 150 patients were treated using this system. Charts and radiographs were reviewed for missed injuries. Radiographic review revealed 2 missed injuries. One patient had additional back pain and a lumbar spine fracture was found during the subspecialist follow-up visit; it was treated nonoperatively. Another patient appeared to have scapholunate widening on the injury radiograph that was not appreciated in the ED. Of the 150 patients, 51 were seen in follow-up by a subspecialist at the authors' institution. An electronic system to organize follow-up with a subspecialist allowed the ED providers to deliver safe and effective care for simple musculoskeletal injuries.

    Surgical resection with curative intent is till the mainstay of treatment for resectable esophageal cancer. Minimal invasive oesophagectomy has the potential to lower morbidity and mortality. In all likelihood, thoracoscopic oesophagectomy in semiprone position gives all the benefits of prone position and can be converted to thoracotomy without change in patient position if needed. The aim of this study is to analyze the feasibility of thoracoscopic oesophagectomy in semiprone position. This is a retrospective analysis of the data of thoracoscopic oesophgeactomy in semiprone position at Kaizen Hospital, a tertiary care center for gastroenterology during the period of December 2011 to December 2012. All surgeries were performed under general anesthesia with a single-lumen endotracheal tube. Esophageal mobilization was done by thoracoscopic approach in a semiprone position and an end-to-end hand-sewn cervical anastomosis was done. Abdominal part was performed by laparoscopic method in 3 patients and by laparotomy in rest of the patients. Total of 12 patients were included in this study. There was 1 conversion to thoracotomy and 1 surgical mortality. Mean operating time for the thoracoscopic part was 103 minutes, mean estimated blood loss for the thoracoscopic part was 110 mL, mean maximum end-tidal CO2 38.5 mm Hg, mean lymph nodes retrieved 14, and all patients had R0 resection. The median intensive care unit stay was 1 day and hospital stay was 8 days. Thoracoscopic part of thoracolaparoscopic oesophagectomy in semiprone position is a feasible option. It gives all advantages of prone position and thoracotomy is possible without change in patient position. However, further large-scale studies are required.

    Reliable results represent the pinnacle assessment of quality of an analytical laboratory, and therefore variability is considered to be a critical quality problem associated with the selenium analysis method executed at Western Cape Provincial Veterinary Laboratory (WCPVL). The elimination and control of variability is undoubtedly of significant importance because of the narrow margin of safety between toxic and deficient doses of the trace element for good animal health. A quality methodology known as Lean Six Sigma was believed to present the most feasible solution for overcoming the adverse effect of variation, through steps towards analytical process improvement. Lean Six Sigma represents a form of scientific method type, which is empirical, inductive and deductive, and systematic, which relies on data, and is fact-based. The Lean Six Sigma methodology comprises five macro-phases, namely Define, Measure, Analyse, Improve and Control (DMAIC). Both qualitative and quantitative laboratory data were collected in terms of these phases. Qualitative data were collected by using quality-tools, namely an Ishikawa diagram, a Pareto chart, Kaizen analysis and a Failure Mode Effect analysis tool. Quantitative laboratory data, based on the analytical chemistry test method, were collected through a controlled experiment. The controlled experiment entailed 13 replicated runs of the selenium test method, whereby 11 samples were repetitively analysed, whilst Certified Reference Material (CRM) was also included in 6 of the runs. Laboratory results obtained from the controlled experiment was analysed by using statistical methods, commonly associated with quality validation of chemistry procedures. Analysis of both sets of data yielded an improved selenium analysis method, believed to provide greater reliability of results, in addition to a greatly reduced cycle time and superior control features. Lean Six Sigma may therefore be regarded as a valuable tool in any laboratory, and

    Domestic pharmaceutical industry has been identified by the Malaysian government as an industry to be developed under its 11th economic development plan. Most homegrown pharmaceutical companies fall under the category of small and medium enterprises (SME) and therefore need to be highly efficient in their operations to compete with the multinationals. Though lean manufacturing is a well-known methodology to achieve an efficient operation, only a small percentage of the local SMEs implement it. The study aims to determine the real success factors in lean implementation through systematic review of relevant literature on lean manufacturing implementation in local companies, onsite observation of a selected SME company, Global Factor Sdn. Bhd. (GFSB), that successfully implemented lean manufacturing followed by actual implementation of lean project at IKOP Sdn. Bhd., a small startup pharmaceutical company. Lean tools like Gemba, value stream map (VSM) and spaghetti diagram were used to analyze and improve a process at IKOP Sdn. Bhd. The literature review showed that the implementation of lean manufacturing at Malaysian SMEs involved in pharmaceutical industry is at its infancy. Study at GFSB indicated that successful implementation of lean manufacturing stems from management support, employee’s commitment, government support and knowledge on lean among employees. Application of lean tools in IKOP Sdn. Bhd. to improve the process cycle efficiency of hand sanitizer, i-Hand 4.0, has shown that the GMP guidelines are not jeopardized. The Kaizen improvement project resulted in 46.3% reduction in lead time. It may be concluded that implementing lean manufacturing in any small local startup pharmaceutical company is beneficial in reducing operational costs and increasing the efficiency and effectiveness and does not conflict with the existing GMP guidelines.

    Vast microbial populations exist in deep-subsurface marine sediments. Although amino acids in sediment pore waters are key compounds in metabolic activities of sedimentary microbes and in remineralization of carbon and nitrogen, to date little is known about their biogeochemical dynamics (e.g., sources and transformation processes) in deep-subsurface sediments. As a new approach to constrain the sources of dissolved amino acids in sediment pore waters, we analyzed compound-specific nitrogen isotopic composition (d15N) and enantiomer ratio (%D) of total hydrolysable amino acids (THAA) in sediment solid phase and dissolved hydrolysable amino acids (DHAA) in sediment pore waters from the same sediment samples. Enantiomer ratio can be an indicator of source organisms of amino acids, because specific D-amino acids (such as alanine, aspartic acid, glutamic acid, and serine) are commonly found in the cell wall complex of bacteria. Compound-specific d15N can be an indicator of microbial metabolism of amino acids, because biosynthesis and degradation of amino acids cause nitrogen isotopic fractionation. Samples were collected from deep-subsurface sediments (up to 172.9 m below seafloor) at the Sagami Trough (Northwestern Pacific) during D/V Chikyu cruise CK09-03. In the sediments deeper than 9 mbsf, %D values of DHAA were 25.9×2.8% in alanine, 24.8×2.1% in aspartic acid, 11.3×2.8% in serine, and 16.3×2.7% in glutamic acid, and %D changes from THAA were +15.3×2.1% in alanine, -0.4×2.4% in aspartic acid, -8.1×6.2% in serine, and 4.6×3.3% in glutamic acid. Compound-specific d15N analysis showed that d15N values of alanine are higher in DHAA than THAA and that d15N values of glycine and glutamic acid are similar between the two fractions (d15N of DHAA - d15N of THAA = +5.8×2.3 permill, +1.9×0.6 permill, -0.3×1.1 permill, respectively). The differences of d15N and %D signatures between DHAA and THAA suggest that the depolymerization of THAA is not the sole source of

    ultimately on sedimentation in the deep basin. For the Miocene and older sediments the drilling, will yield information about the nature, paleoenvironments and age of deposits enabling an astronomically-tuned Neogene time scale to be refined for the period of Aquitanian through Langhian interval. 3) The Messinian extreme event represents a unique sedimentological, hydrological, oceanographic, biological and probably climatological crisis in Earth history. It is a unique case to study the impact of sea-level drop (more than 1000 m, one order of magnitude greater than Late Quaternary glaciations) on sedimentary river behavior, deltaic and evaporitic deposition and ensuing biotic crisis. Deep drilling with the R/V Chikyu is the only way to go through the complete series of evaporites in the Provence Basin, sample the initiation and evolution of the crises, the first deposits related to the lowering of sea-level on the one hand and to the salinity crisis on the other. 4) Finally, this drilling will represent the first opportunity to study the composition and functioning (metabolic processes and products, regulation of populations, etc.) of the microbial communities (bacteria, Archaea, viruses, fungi and protists) from the deep biosphere of the Mediterranean Sea. An additional and linked MSP GOLD-2 project has the objectives of recovering a unique global Pliocene records preserved on the shelf (Rabineau et al., this congress, session CL 1.6) We invite all interested scientists to join us in planning and promoting this drilling project. We are proposing an IODP Magellan workshop in Banyuls in October 2010 to bring together all interested scientists and stake-holders around these proposals and other drilling projects in the Mediterranean Sea (e.g. ICDP). Please contat us at the earliest opportunity.

    Chikyu Expedition 319 was the first cruise of the Integrated Ocean Drilling Program (IODP) where riser drilling was performed and real-time mud gas monitoring was conducted, because this technique requires drill-mud circulation. In contrast to conventional IODP drilling that uses drill water in combination with lost circulation, during riser drilling the drill mud returns back to the surface through a riser pipe which encases the drill pipe. The dissolved gas is extracted from returning drill mud, analyzed in real time and sampled for noble gas and stable isotopes studies. This technique has been applied in the past on scientific continental drilling projects of e.g. the International Continental Drilling Program. Expedition 319 is part of the NanTroSEIZE project, a multiexpedition, multistage IODP drilling program focused on understanding the mechanics of seismogenesis and ruptures propagation along the Nankai accretionary prism. Riser drilling was carried out on Hole C0009 that intersects the cover sediments of the Kumano Basin and probably penetrates into the accretionary prism below. Site NT2-11 is located approx. 60 km SE of the harbour of Shingu, Japan. Real-time mud gas monitoring was performed in Hole C0009 during drilling from 703 mbsf (meter below sea floor) down to 1594 mbsf and during hole enlargement from 703 mbsf to 1569 mbsf. Both datasets show similar gas distribution at depth. Gas was furthermore extracted, sampled and analyzed from drill cuttings. Drill mud gas is generally composed of air and gases that derive from the formation. The principal formation gas in drill mud from both drilling phases and in cuttings was methane. Up to 14 vol % CH4 was detected during drilling and up to 3 vol % during hole enlargement. Down to 800 mbsf and below 1280 mbsf, the methane concentration in drill mud is lower than in the surrounded interval, where methane peaks at several depths. At 1280 mbsf an unconformity is indicated from lihology, in seismic and

    The Mw 9.0 Tohoku earthquake and accompanying tsunami produced the largest slip ever recorded in an earthquake and devastated much of northern Japan on March 11, 2011. The IODP proposal for JFAST (Japan Trench Fast Drilling project) planned to drill into the Tohoku subduction zone using the research ship Chikyu, measure the fault zone physical properties, recover fault zone material, and install an observatory to directly record the temperature anomaly caused by frictional slip during the earthquake. Considering the significant technical and operational challenges related to the great water depth of ~7,000 meters, and timing constraints, the observatory needed to be both robust and simple. After frequent discussions among scientists, engineers and operators, we decided to prepare two different types of observatories. 1. Autonomous MTL (Miniature Temperature Logger) observatory. The important temperature monitoring is accomplished by 55 MTLs attached to a string (Vectran rope) which is suspended inside a 4.5" casing in the borehole. The string latches at the top of the casing to allow retrieval using the remotely operated vehicle (ROV) Kaiko operated by JAMSTEC. This observatory avoids risks associated with a thermistor cable and wellhead data logger, and increases reliability by applying proven technologies. Perhaps most importantly, this configuration allows flexibility in defining the final depth distribution of the temperature sensors. This is advantageous since information of the exact depth of the fault zone will be known only after drilling and logging. Also, the judicious placement of weak links along the string helps to minimize possible loss of the entire sensor string if it is clamped by post-seismic movements that deform the casing. 2. Telemetered PT (Pressure and Temperature) observatory. Based on the previous deployment experience of the NanTroSEIZE C0010 observatory, we prepared another system that enables long term monitoring and repeated ROV data

    A daily gridded precipitation dataset for the period 1951-2007 was created by collecting and analyzing rain-gauge observation data across Asia through the activities of the Asian Precipitation - Highly Resolved Observational Data Integration Towards Evaluation (APHRODITE) of water resources project. They are available at http://www.chikyu.ac.jp/precip/. Utilization of station data is ideal for analyses of climatic trends, especially for those of extreme events. However, there was an increasing demand for accurate high-resolution gauge-based precipitation analyses. Rain-gauge based products are sometimes used for assessing trends of climate models or that of river runoff through driving hydrological models, because they are convenient and long records. On the other hand, some information is lost during the gridding process. Hence, in-house results of testing interpolation scheme, quality control and homogenization may give important information for the users. We will present such results as well as our quality control (QC) in the APHRODITE project activities. Before gridding, 14 objective QC steps were applied to the rain-gauge data, which mainly includes position checking, duplicate data checking and inhomogeneity and spatiotemporal isolation etc. Details are described in Hamada et al. (2011). For Chinese data, basic QC steps such as duplicate checking and position checking have been made by the local meteorological agency. Hence we made homogenization test and spatial correlation analyses separately. For 756 Chinese daily temperature stations, we applied Multiple Analysis of Series for Homogenization (MASH) developed by Szentimrey (1999, 2008). The results show this statistical method we used has a good performance to detect the discontinuities in climate series caused by station relocation, instrument change etc. regardless of the absence of metadata. Through the homogenization, most of discontinuities existed in original temperature data can be removed, and the

    pulse and 2 ms pulse width. After these tests were completed, we installed all sensors to Matsushiro Seismological Observatory and conducted noise evaluation test before and after vibration and shock tests. As for the broad-band seismometer CMG3T, vibration test was conducted by Guralp Systems Ltd. in U.K. with same parameters as our test. After delivered, noise evaluation test was conducted in Matsushiro as other sensors. As a result of the noise evaluation test, Power Spectral Density (PSD) was calculated using background noise for sensor evaluation. We confirmed that PSD plots of all sensors have same response before and after these tests. The peak of microseism around 0.2Hz can be clearly confirmed in the PSD plot of the CMG3T, geophone and tiltmeter. Finally, we confirmed that the responses of these sensors have good coherence with that of the reference sensor which was general package of land-type CMG3T and this result is consistent with each specification of sensors. After final noise evaluation test was completed, all of sensors were loaded to D/V Chikyu for IODP Expedition 332, and were successfully installed to Site C0002 observatory in December, 2010.

    Quantified grid observation data at a reasonable resolution are indispensable for environmental monitoring as well as for predicting future change of mountain environment. However quantified datasets have not been available for the Himalayan region. Hence we evaluate climatological precipitation data around the Himalayas by using Precipitation Radar (PR) data acquired by the Tropical Rainfall Measuring Mission (TRMM) over 10 years of observation. To validate and adjust these patterns, we used a dense network of rain gauges collected by the Asian Precipitation—Highly Resolved Observational Data Integration Towards Evaluation of Water Resources (APHRODITE Water Resources) project (http://www.chikyu.ac.jp/precip/). We used more than 2600 stations which have more than 10-year monthly precipitation over the Himalayan region (75E-105E, 20-36N) including country data of Nepal, Bangladesh, Bhutan, Pakistan, India, Myanmar, and China. The region we studied is so topographically complicated that horizontal patterns are not uniform. Therefore, every path data of PR2A25 (near-surface rain) was averaged in a 0.05-degree grid and a 10-year monthly average was computed (hereafter we call PR). On the other hand, for rain-gauge, we first computed cell averages if each 0.05-degree grid cell has 10 years observation or more. Here we refer to the 0.05-degree rain-gauge climatology data as RG data. On the basis of comparisons between the RG and PR composite values, we defined the parameters of the regressions to correct the monthly climatology value based on the rain gauge observations. Compared with the RG, the PR systematically underestimated precipitation by 28-38% in summer (July-September). Significant correlation between TRMM/PR and rain-gauge data was found for all months, but the correlation is relatively low in winter. The relationship is investigated for different elevation zones, and the PR was found to underestimate RG data in most zones, except for certain zones in

    The installation of LTBMS (Long Term Borehole Monitoring System) for NanTroSEIZE (Nankai Trough Seismogenic Zone Experiment) C0002 riserless hole was successfully carried out as part of IODP Expedition 332 operations by DV Chikyu in November - December 2010. The water depth of the site and penetration depth of the hole are 1937.5 m and 980 mbsf respectively. Casing (9-5/8") was set to the depth of 888 mbsf and below the CORK head, 3-1/2" tubing was deployed inside the casing as the support structure for the downhole instruments. Within the rat hole section, two pressure ports, a strain meter, a tilt meter, a broadband seismometer, geophone, and accelerometer were deployed. These seismic and geodetic sensors were set within the borehole, and coupled to the formation via cement whose physical properties (Young's modulus, Poisson's ratio, density) were adjusted to fit the formation's properties. Screen sections were set to access the pore fluids, while isolating them from the sea floor and the lower lithological units by a swellable packer, and cement, respectively. At the top of wellhead, and at the apex of the 3-1/2" tubing assembly, a CORK head was landed. The CORK head holds the pressure sensor unit (4 pressure sensors), underwater mateable data connectors (connected to the cemented sensors), and hydraulic valves to access and sample formation fluids by ROV. The major scientific features of the Hole C0002G (riserless) LTBMS are sensors monitoring multiple parameters related to seismic, geodetic and pore fluid behavior simultaneously at distinct, multiple, layers within the same borehole. The main technical difficulties in the LTBMS development are as follows: (1) Reduction method for current-induced VIV (Vortex Induced Vibration) (2) Borehole coupling for seismic and geodetic sensors (3) Anti-vibration/shock and protection method for borehole sensors/instruments (4) Attachment and protection for sensor cables and pressure lines (5) Zone isolation for multi

    A family support/treatment program was provided to thirty-three cases where a drinking family member (identified patient) had shown alcohol related problems but not yet admitted the problem. After a period of between thirteen and twenty-one months of family treatment, fourteen (42.4%) identified patients started their own treatment. The only statistically significant factor that was related to the patients' treatment program participation was the continuation of family members' involvement in a family treatment program. Among the thirty-three cases, a little less than one half (48.5%) continued the family program. In order to increase the patients' participation, it is crucial to encourage family members to continue their family support/treatment program. In order to identify factors that contribute treatment continuation as well as dropouts, workshops were held with those who dropped out and those who continued the family treatment program. The Total-Quality-Management (TQM) affinity and arrow diagram techniques were employed to classify the participants' statements and to find cause-effect relationships among the identified factors, respectively. Five family treatment discontinuation factors were identified: 1) a lack of information about family support program, 2) resistance against a "family change" orientation in family treatment program, 3) family member burnout, 4) a misfit between family needs for immediate problem solutions and what family program offers, and 5) a temporal improvement of patients' drinking problems. While widely varied factors were found to contribute discontinuation, only a very few factors were identified to facilitate the treatment continuation. It was concluded that treatment discontinuation, rather than continuation, was the norm among the families of problem drinkers. Based on the above findings, three kaizen plans were proposed. First, in order to make sure that family members obtain necessary information about the family support

    The aim of this study is to identify independent pre-transplant cancer risk factors after kidney transplantation and to assess the utility of G-chart analysis for clinical process control. This may contribute to the improvement of cancer surveillance processes in individual transplant centers. 1655 patients after kidney transplantation at our institution with a total of 9,425 person-years of follow-up were compared retrospectively to the general German population using site-specific standardized-incidence-ratios (SIRs) of observed malignancies. Risk-adjusted multivariable Cox regression was used to identify independent pre-transplant cancer risk factors. G-chart analysis was applied to determine relevant differences in the frequency of cancer occurrences. Cancer incidence rates were almost three times higher as compared to the matched general population (SIR = 2.75; 95%-CI: 2.33-3.21). Significantly increased SIRs were observed for renal cell carcinoma (SIR = 22.46), post-transplant lymphoproliferative disorder (SIR = 8.36), prostate cancer (SIR = 2.22), bladder cancer (SIR = 3.24), thyroid cancer (SIR = 10.13) and melanoma (SIR = 3.08). Independent pre-transplant risk factors for cancer-free survival were age <52.3 years (p = 0.007, Hazard ratio (HR): 0.82), age >62.6 years (p = 0.001, HR: 1.29), polycystic kidney disease other than autosomal dominant polycystic kidney disease (ADPKD) (p = 0.001, HR: 0.68), high body mass index in kg/m2 (p<0.001, HR: 1.04), ADPKD (p = 0.008, HR: 1.26) and diabetic nephropathy (p = 0.004, HR = 1.51). G-chart analysis identified relevant changes in the detection rates of cancer during aftercare with no significant relation to identified risk factors for cancer-free survival (p<0.05). Risk-adapted cancer surveillance combined with prospective G-chart analysis likely improves cancer surveillance schemes by adapting processes to identified risk factors and by using G-chart alarm signals to trigger Kaizen events and audits for root

    sedimentation during the crisis? What are the vertical movements (tectonic/isostatic responses) associated to margin unloading and basin loading? - What are the present-day fluid dynamics related to the salt layer? Their impact on the deep biosphere? The response to all of these questions would only come from drilling through the complete Messinian succession. It would represent an outstanding opportunity to unravel the history of extreme environmental changes during the Messinian and a unique chance to constrain the age, nature and paleo-environment of deposition of the deep-basin Messinian sequence. For that reason, in the framework of the IODP drilling program, we propose to sample and log two different sites in the western and eastern Mediterranean basins, with the new scientific riser drillship Chikyu perfectly adapted to overcome all safety problems. In order to promote a continuous sedimentary record of the MSC since the pre-crisis paleo-environmental changes, the sites should be drilled in areas where the Messinian salt is tabular and exempted of significant tectonic influence. A complete set of integrated studies (sedimentology, geochemistry, micropaleontology, bio-and cyclostratigraphy) should be carried out. This project opens the perspective of a new intellectual and scientific adventure that we expect to be as rich and exciting as the discovery of this unusual event was.

    objectives related to the MSC. Among these proposals, one will be fully dedicated to the MSC event. Improved quality of seismic data has allowed important advances in the recognition and understanding of MSC seismic markers (surfaces and depositional units) and lithological and stratigraphical calibrations are now critical. Therefore, the drilling strategy must include multiple sites covering representative locations of both Western and Eastern Mediterranean basins. A series of critical drilling targets were thus identified as follows: - A first set of drilling targets, dedicated to shallow water (< 2500 m water depth) MSC markers, includes the Messinian clastic wedges, the erosion surfaces and the MSC deposits (including thin salt bodies) trapped in small topographic lows observed at various water depths between the shoreline and the abyssal plain. Up to 10 sites, presented in this work, could be drilled with the riserless R/V Joides Resolution, provided the safety conditions are met; - Another critical drilling target is the full recovering of undeformed MSC sequence (including the Tortonian-Messinian and the Messinian-Zanclean boundaries) in the deep water (>2500m) of both the eastern and western Mediterranean basins. This will be possible thanks to R/V Chikyu riser drilling vessel and will be the scope of a second MSC IODP proposal. DREAM Team: A. Giovanni galod@locean-ipsl.upmc.fr, H.

    security; loss of confidence in government; failure of publicly funded projects; damage to the environment; ethics violations, and the list goes on; with local, national and even international consequences. The Plan-Do-Check-Act process, also known as the "process approach" can be used at any time to establish and standardize a process, and it can also be used to check periodically for "process creep" (i.e., informal, unauthorized changes that have occurred over time), any necessary updates and improvements. While ISO 9001 compliance is not mandated for all government agencies, if interpreted correctly, it can be useful in establishing a framework and implementing effective management systems and processes.4 Another method that can be used to evaluate effectiveness is the scorecard definitions in Mallory's Process Management Standard5 as a basis for evaluating work on the process level on effective, and continuously improved and improving processes. With processes on the lower end of the scale, agencies are vulnerable to a great many risks, with employees and managers making up many of the rules as they go, leading to the above listed negative results. Without clear guidance for nominal operations, off-nominal situations can, and do, increase the likelihood of chaos. In an increasingly technical environment, with inter-agency communication and collaboration becoming the norm, agencies need to come to grips with the fact that processes can become rapidly outdated, and that the technical community should take on an increased role in the maturation of the agency's processes. Industry has long known that effective processes are also efficient, and process improvement methods such as Kaizen, Lean, Six Sigma, 5S, and mistake proofing lead to increased productivity, improved quality, and decreased cost. Again, government agencies have different concerns, but inefficiencies and mistakes can have dire and wide reaching consequences for the public that they serve. While no one goes
