滋賀県南部の桐生試験地において、鉛直及び横方向の地中水移動過程における溶存有機態炭素の動態解明を目的に、土壌水、地下水、渓流水を採取し、三次元蛍光分析を行った。検出されたピークは、難分解性フルボ酸様物質(A)、易分解性フルボ酸様物質(C)、変質性フルボ酸様物質(M)、アミノ酸様物質(T)であった(Wu et al., 2009)。土壌水のフルボ酸様物質の蛍光強度は表層0-20cmの鉛直浸透過程で分解・吸着によって急低下した。下層では蛍光強度が表層に比べ緩やかに低下するとともに、ピークM,Tが複数回確認された。地下水帯表層でも強度の低下が継続した。しかし、地下水帯下層では再び蛍光強度が上昇し、ピークC,Mが下層土壌層 と同程度の強度になった。Katsuyama et al. (2005)は、地下水帯下層が斜面部で基岩に浸透した地下水によって涵養されることを示したが、本結果はこの水が土層の蛍光特性を保持したまま移動することを示唆する。飽和帯地下水帯での横方向移動から渓流流出に至る過程では蛍光強度の変動は小さかった。以上から、DOC蛍光特性は地下水帯に至るまでに概ね決まるとともに、渓流へのDOC供給源を考える場合、地下水帯の層位に着目した質の評価が必要である。

In management theory,importance of decision making had been often discussed. Researchers in the past, however, rarely dealt with a cognitive process after decision making. Leon Festinger's Cognitive Dissonance Theory is one of the rare researches that explaines effectively people's pro-decision making cognition. The theory has two basic hypotheses: (1) The existence of dissonance, being psychologically uncomfortable, will motivate the person to try to reduce the dissonance and achieve consonance. (2) When dissonance is present, in addition to trying to reduce it, the person will actively avoid situations and information which would likely increase the dissonance. Using the theory, we might be able to come up with some new perspectives on some complex issues such as a process of decision making and cognition, a relationship between motivational factors, a relationship between motivational factors and motivation, and communication gaps in various relationships.

A helicopter-borne magnetic survey system was developed in use of a nose boom magnetic sensor, which enables safe and practical operation of low-altitude high-resolution survey even in mountainous regions of very steep topography and high elevation. The system consists mainly of airborne Cesium magnetometer, 3-axis fluxgate magnetometer, GPS receiver, navigation unit, data-acquisition PC, etc., incorporating with other equipment on the ground including base station magnetometer and reference station GPS receiver.<br>The nose boom magnetic sensor is situated rather near the helicopter body and cannot be free from its magnetic noise, though the boom itself is made non-magnetic. The 3-axis fluxgate magnetometer is the equipment to compensate aircraft's magnetic noise field. Theoretical consideration for passive magnetic compensation and the method of actual data processing for it are discussed. Then the software for magnetic compensation was developed and applied to the data of actual verification survey, and the procedure was proven to accomplish post-flight magnetic compensation properly.

The First Oil Crisis started as a result of the six Persian Gulf members of OPEC announcing a raise in the posted price of crude oil on October 16, 1973 and OAPEC deciding to reduce oil production by 5% per month on the following day, touched off by the breakout of the Yom Kippur War. Japan was faced with an unprecedented dilemma between the Arab countries, who strongly demanded Japan to condemn Israel, and the United States who pressed Japan to align with their Middle East policy based on diplomatic relations with Israel. When the Arabs announced a 25% cut of oil supply on November 4, the European countries, similarly to Japan, who were scarce on resources, immediately criticized Israel, and declared support for the Arabs. However, the Japanese government was hesitant to criticize Israel. And the Arab countries pressed to intensify oil supply reduction unless Japan announced to break off diplomatic relations with Israel in the case Israel would not obey the UN Security Council Resolution 242. On the other hand, U.S. Secretary of State Henry Kissinger restrained Japan by stating that condemning Israel would hinder Middle East peace talks with the United States and that cooperative relations with the U.S. would be profitable for Japan from a long-term view. On November 18, the Arab countries announced that they would release the European countries, excluding Holland, from the weighted oil supply reduction measure of 5% from the benchmark set on December, because the European countries had criticized Israel. As a result, the criticism of the weakness of the Japanese diplomacy in attaining resources made the headlines of the Japanese newspapers. How was the Japanese government to escape such dilemma? The Japanese government finally criticized Israel by name and made its pro-Arab positioning clear in the statement made by Chief Cabinet Secretary Nikaido on November 22. Further on December 10, Deputy Prime Minister Takeo Miki, as special envoy, left for eight Middle Eastern countries to offer economic and technical aid. At first glance, the Japanese government took a pro-Arab policy without accepting the warning of the Unites States. This document, however, will empirically clarify that the U.S.-Japan friction related to Japanese Middle East policy was resolved before November 22 in the midst of the development of multilateral diplomacy for the “Kissinger Plan”, a unified framework among Japan, the U.S. and the European countries, and that the Japanese diplomacy during the First Oil Crisis achieved to broaden the permissible scope of the United States.

軟卵産生鶏の大腿骨における骨髄骨の組織学的態度を卵が子宮部に存在する時期について調べ, 正常卵産生鶏の骨髄骨と比較検討した.軟卵産生鶏の骨髄骨は正常卵産生鶏に比べ, 骨髄腔内に過度に形成されていた. これらの骨髄骨は幅が厚く, 基質には不規則に轡曲した層板構造が観察され, 基質内部に埋没する骨小腔の一部は拡張し, 空胞化していた.軟卵産生鶏における骨髄骨の基質組成は, 組織化学的観察によると, 正常卵産生鶏とは逆にコラーゲン線維が多く, 酸性粘液多糖類は少なかった. また, コンタクトミクロラジオグラフィによると, これ骨髄骨は高度に石灰化していた.軟卵産生鶏の骨髄骨表面に出現する破骨細胞は正常卵産生鶏に比べ, 数が少なくまた萎縮したものが多かった. これらの破骨細胞は酸性ホスファターゼおよびコハク酸脱水素酵素活性が弱い傾向を示した.これらのことから, 軟卵産生鶏の骨髄骨では卵殻形成に必要なカルシウムの放出が不活発であることがうかがわれた.
