平成 15 年度に始まった高等学校普通科における教科 「情報」 を履修した学生が昨年度より大学に入学しはじめている.これに伴い大学では従来の情報リテラシ教育のあり方の見直しを迫られている.そこで本学では,教科 「情報」 の履修状況と関連した情報リテラシ修得状況を,平成 18 年度より新入生についてアンケート調査している.今年度も引き続き調査を行った結果,高校における教科 「情報」 の履修の傾向が安定してきていること,教科を履修させていない高校がまだ残っていること,アプリケーション利用に関するスキルは身についているが情報セキュリティに関するリテラシが十分とは言いかねること,プログラミングを習いたいとする意欲が高いことなどが明らかになった.The new subject "Information Study" in senior high school started in 2003 fiscal year and the students who finish the subject have come to enter the universities since last year. It forces universities to reconstruct the curriculum to fit the situation. Therefore, we made questionnaire surveys of the students who entered the university in each academic year from 2006 about the learning situation of the new subject and related information literacy. According to the result of this academic year, it was clarified that taking the subject "Information Study" in senior high school stably have tendencies, there still remains some schools which do not open the subject, the students have mastered the usage skill of software applications but have not enough mastered about information security literacy, and their greediness for learning programming languages is high.

On April 26th 1986, an accidental explosion occurred at Chernobyl nuclear power station #4, located in the Ukraine, in the former Soviet Union. From May 1991, in order to prevent internal exposure to cesium-137 (^<137>Cs) in the inhabitants of the Chechersk district of the Gomel region in the Republic of Belarus, which was an area highly contaminated by the Chernobyl accident, the author continuously measured internal ^<137>Cs accumulations within inhabitants of the district with a whole-body counter, and the levels of ^<137>Cs in milk, beef, pork, mushrooms, potatoes and flour with a GM-semiconductor detector. Then the author analyzed the relationships between the inhabitants′ daily habits and their measured cesium levels. The author measured ^<137>Cs accumulation within 528 inhabitants and in agricultural produce in the Chechersk disrict. There was no correlation between the internal ^<137>Cs levels within inhabitants and the surface contamination by ^<137>Cs within the residential area. However, a comparison of internal exposure levels by age and sex revealed a significant variation between adult males and both male and female children, and between adult males and females (p<0.001). Food supplied in school was the cause of lower levels in children because it was strictly controlled by the local health authority. The difference between adult males and adult females was thought to be due to the difference in the length of working time in the fields, or in the amount of food from pastures, lakes and forests. Some of the measurement values of agricultural produce with the GM-semiconductor detector exceeded the provisional standards of the Ministry of Health of the Republic of Belarus, where milk, beef, pork and mushrooms had been measured while potatoes and flour had not. Results for milk (r=0.829), beef (r=0.916), pork (R=0.896) and mushrooms (r=0.670) all showed a strong correlation with the concentration of ^<137>Cs on the surface for fields and pastures, while those for potatoes and flour showed no correlation. According to this survey, the internal levels of ^<137>Cs of inhabitants living within the contaminated areas were not related to the concentration of ^<137>Cs in the residential areas, but to the foodstuffs they consumed. Thehefore, by avoiding contaminated foodstuffs, the inhabitants could reduce internal exposure and their risk.

A genetic analysis of wild-caught tetsugyo from Yutori-numa Pond, Miyagi Prefecture, a long-finned fish of uncertain origin designated as a National Natural Monument in Japan, demonstrated that some specimens were hybrids of goldfish (Carassius auratus) and crucian carp (genus Carassius). Phylogenetic analysis of sequences from part of the D-loop region of mitochondrial and nuclear DNA of 87 Yutori-numa tetsugyo indicated that 66 belonged to the goldfish group and 21 to the Japanese crucian carp group, subsequent PCR-RFLP analysis of c-myc gene revealing three different restriction fragment digest profiles, 21 and 60 specimens possessing goldfish or Japanese crucian carp genes, respectively, and the remaining 6, both genes, indicating their hybrid origin.

本稿は,職人の地域的移動パターンの側面から輪島漆器の生産地域の拡大を考察することを目的とする.漆器関連事業所の分布は, 1960年代における輪島漆器業の発展に伴い拡大した.また1960年代には輪島漆器業の技能継承システムである徒弟制が変質し,漆器業とは無関係な出自をもつ労働力が広範囲から参入した.職人の移動をライフパスとして分析した結果,(1)家業継承者を主体とした,中心地域において滞留するパターン,(2)周辺・外縁地域出身で,中心地域で修業し,独立後周辺地域に移動するパターン,(3)中心地域出身で,独立後周辺地域に移動するパターン,が抽出された,輪島漆器の生産地域の拡大は,徒弟制の変質によって増加した漆器業とは無関係な出自をもつ,(2)および(3)のパターンに該当する職人が,良好な生産・居住環境を確保した結果生じたものである.同時に(1)のパターンは中心地域における漆器関連事業所の集積を継続させている.
