    This paper tries to present a careful analysis of current trends and challenges to importing Japanese model of teachers' professional development. The objective is to examine what "we" can learn from Japanese approach to improving instruction, especially "Jugyou Kenkyu" (Lesson Study) as a collaborative research on the teaching-learning process.…

  2. Ethnography for Teachers' Professional Development: Japanese Approach of Investigation on Classroom Activities

    In this paper, we examine how journal and ethnography field notes in Jugyou Kenkyu (lesson study) help teachers to understand the diverse range of talents and abilities of their students. Especially, we focus on how ethnography field note and reflective papers (karate) help teachers to change their assumptions about student learning. The data…

    Two kinds of Japanese guidelines for the data acquisition protocol of oncology fluoro-D-glucose-positron emission tomography (FDG-PET)/computed tomography (CT) scans were created by the joint task force of the Japanese Society of Nuclear Medicine Technology (JSNMT) and the Japanese Society of Nuclear Medicine (JSNM), and published in Kakuigaku-Gijutsu 27(5): 425-456, 2007 and 29(2): 195-235, 2009. These guidelines aim to standardize PET image quality among facilities and different PET/CT scanner models. The objective of this study was to develop a personal computer-based performance measurement and image quality processor for the two kinds of Japanese guidelines for oncology (18)F-FDG PET/CT scans. We call this software package the "PET quality control tool" (PETquact). Microsoft Corporation's Windows(™) is used as the operating system for PETquact, which requires 1070×720 image resolution and includes 12 different applications. The accuracy was examined for numerous applications of PETquact. For example, in the sensitivity application, the system sensitivity measurement results were equivalent when comparing two PET sinograms obtained from the PETquact and the report. PETquact is suited for analysis of the two kinds of Japanese guideline, and it shows excellent spec to performance measurements and image quality analysis. PETquact can be used at any facility if the software package is installed on a laptop computer. PMID:23782777

    varieties, estimated at 85-100 t/ha for potato, 75-85 t/ha for beet and 12-15 t/ha for wheat (Evans 1977). These are far higher than the yields commonly obtained in practice. World average yields were only 1/6th of the potential for potato, 1/6th for wheat and 2/5th for sugar beet in 1995. Utilization of the crop The major part of potato production is usually used for human consumption. Human consumption of potatoes however has declined in the industrialised countries as the standard of living has increased. In these countries an increasing proportion of the crop is used for manufacturing products such as crisp, oven-ready chips, dehydrated potato powder. Thus, in Hungary the consumption of potatoes per person decreased from 110 kg in 1951/1960 to 60 kg in 1995, whereas the consumption of processed potatoes increased from 1 to 15 kg/person during this period. Uptake of potassium Potassium is the nutrient taken up by potato in the greatest quantity, it also takes up much nitrogen and appreciable amounts of phosphorus, calcium, magnesium and sulphur (Perrenoud 1993). Maximum uptakes by different varieties in Japan range between 140 and 267 K2O (Kali Kenkyu Kai 1980). In England, potatoes grown on the " blueprint" system and giving the very high yield of 77.7 t/ha took up 450 kg/ha K2O (Anderson and Hewgill 1978). Brazílian experiments with 6 varieties showed the following uptakes (kg/ha): potassium 207-367 (Motta 1976). Removal of potassium by tubers 23 experimental crops in France (Loué 1977), -with a mean yield of 37.3 t/ha tubers removed: 196 kg K2O, respectively. It is equal to 5.3 kg K2O per 1 tonne tuber. Motta Macedo (1976) reports the following removals in kg/ha for 6 varieties grown in Brazíl: K2O: 118-192. In 14 experiments in India (Grewal and Singh 1979) a mean yield of 28.8 t/ha tuber was obtained which removed an average of 91 kg/ha K2O. At very high yield level, nutrient removal in tuber is very high. Anderson and Hewgill (1978) report a yield of 90 t
