    I wonder what most people think when they hear of small children playing on computers in kindergarten. One can almost hear the responses: "Why should kindergarten children have to use computers?" Small children are using computers? It's much too earlyl" "At kindergarten children should be singing, playing games, and making mud pies!" A computer is the epitome of the artificial. If we really make a mess of things, humans will become slaves to computers. What can they be thinking, putting such things in kindergartens as a child's toy? Many people who think in this way have never touched a computer, and it often seems the case that these "emotional opponents" are opposed to them only because of their own preconceptions. There is still a preconception that" a computer = a square machine like a TV with lots of difficult-looking keys". Computers are now in virtually all of the electronic appliances we use every day, refrigerators, washing machines, vacuums and televisions, and we think nothing of it. We live each day using computers, but only the "square" computer invites such contempt. Why is this the case? On the other side, there are the "proactive endorsers", who think "Computers have spread thus far in society and schools, so we must let children become familiar with them from a very young age!" These people often seem to want to teach everyone everything. There is much to know about the image and use of computers. They seem to think that if adults don't teach them, children won't understand anything. On this point, they are at the same level as the "emotional opponents", in that they conceive of computers as being something out of the ordinary. PMID:10770080

  2. [The development of the Japanese pharmaceutical industry (Part 8) - the change of opium alkaloid opioid analgesics in Japanese pharmaceutical companies.].

    After the Japan-England Friendship and Commercial Treaty of 1858 (Ansei 5), narcotic drugs have been strictly regulated by laws. The production of opium alkaloid analgesics, mainly morphine, became active in Japan after World War I (1918, Taisho 7). Having released the "Cancer Pain Relief" guideline by the WHO in 1986 (Showa 61) and the morphine sulfate controlled-release tablet "MS Contin" in 1989 (Heisei 1) in Japan, the demand for morphine in Japan expanded remarkably. Today, several more kinds of strong opioid analgesics are available for cancer pain treatment in Japan. An increase in the use of strong opioid analgesics is expected in the future.

    Crystal-rich (40-50 vol.-%) intermediate to silicic lava has been the primary eruptive product of several recent hazardous eruptions: Mt. Pinatubo, Philippines (1991), Soufriere Hills, Montserrat (1995-present), and Unzen, Japan (1990-1995). Despite this association with such devastating eruptions, the formation, timing, and evacuation of such magmas is not well understood: do such eruptions tap a long-lived, multi-cycle crystal mush, or, is it generated in a single magmatic cycle prior to eruption? We are exploring these questions at the Unzen Volcanic Complex, Nagasaki-ken, Japan where a 500 ka history of crystal-rich dacitic dome eruptions has built the Unzen Volcanic Complex. Previous studies (e.g. Nakamura, 1995) have demonstrated the role of mafic recharge in rejuvenating crystal mush a few months prior to the most recent eruptions, but the history of the mush is unknown. Preliminary U-Th/U-Pb in zircon geochronology from the most recent eruption (Heisei-Shinzan; 1990-1995) and the 1792 dome collapse lava (Tenguyama; erupted 4.1±0.8 ka) reveal a complex history of individual zircons. Unpolished rims from the 1990-1995 eruption range in age from ~24.6 to 180 ka, while interior ages (on polished grains) are older, ranging from 60 to 200 ka. Zircons from Tenguyama record unpolished rim model ages of ca. 21 to 90 ka and interior ages of 37 to 225 ka. Rim-interior age differences range from 24 to 122 ka and 6 to 180 ka for Heisei-Shinzan and Tenguyama, respectively. No model ages younger than 20 ka have so far been determined. This leads to the hypothesis that eruptions at Unzen are tapping a long-lived, multi-cycle mush of significant longevity. Acquisition of additional U-Th/U-Pb data, including trace elements from other Unzen domes ranging in age back to 440 ka, is underway to test this hypothesis and more tightly link volcanism with subsurface processes.

    [Purpose] The purpose of this study was to clarify whether walking speed affects acceleration variability of the head, lumbar, and lower extremity by simultaneously evaluating of acceleration. [Subjects and Methods] Twenty young individuals recruited from among the staff at Kurashiki Heisei Hospital participated in this study. Eight accelerometers were used to measure the head, lumbar and lower extremity accelerations. The participants were instructed to walk at five walking speeds prescribed by a metronome. Acceleration variability was assessed by a cross-correlation analysis normalized using z-transform in order to evaluate stride-to-stride variability. [Results] Vertical acceleration variability was the smallest in all body parts, and walking speed effect had laterality. Antero-posterior acceleration variability was significantly associated with walking speed at sites other than the head. Medio-lateral acceleration variability of the bilateral hip alone was smaller than the antero-posterior variability. [Conclusion] The findings of this study suggest that the effect of walking speed changes on the stride-to-stride acceleration variability was individual for each body parts, and differs among directions.
