鳥類でのDNA研究はシブリーらによるDNA-DNAハイブリダイゼーションによる解析を経てその後多くはミトコンドリアDNAによる研究がすすめられてきた. 第4回の国際ペンギン会議(2000年9月, チリ)での演題も多くはペンギンの行動生理学や繁殖保護に関するものであり, DNAの分析の手法を用いた発表は, ミトコンドリアDNA, マイクロサテライトと私たちのペンギンMHC(Major Histocompatibility Complex主要組織適合抗原複合体, MHCと略す)の3件であった. いずれも参加者から高い関心と期待を寄せられた. MHC解析の有用性が関心を呼んだのだろうか, MHC分析をしてみたいとのいくつもの申し出があった. ペンギン研究の舞台へのMHCの初登場は成功をおさめたようである. 本稿では, MHCの舞台でペンギンとペンギンMHCを含めたペンギンDNA研究の現況を披露したいと思う.

In the first report I have compared the elements in soil and drink water of 14 so called long life and 7 short life villages.This time I have analysed those of 10 long life and 12 short life villages (Table 1, 2). By their milligram equivalent ratio, I could described most clearly the difference between both villages, that is the ratio of Mg/Ca, Ca/K, Ca/Ca+Mg+K+Na, Ca-Na (Fig. 1, 3). Over again by the distributions curve of those equivalent ratio, it shows more evidently the difference both villages, such as the ratio of Mg/Ca on the lengthwise the ratio of Ca-Na on the breadthwise (Fig. 4, 5, 6).Farther I have analysed the trace elements in soil, such as Co, Cr, Cu, Ni, Cd, and that of short life villages content always 2-3 times more than that of long life villages (Table 3).

Characteristic structure of Cl-amphibole is reviewed, and its application to chemical zoned amphibole from the Ramnes cauldron is summarized.Large ionic radius of Cl− brings geometrical and chemical effects to the amphibole structure. In the Cl-amphibole, the double chain is significantly deformed to fit expanded octahedral strips, which is achieved by substitution of IVAl for Si (geometrical constraint). The Cl− projects toward the A site and there is a interaction between Cl− and cations in the A site (A site constraint). The short range order of Fe2+-Cl− is observed in Cl-amphibole (chemical constraint). These constraints simultaneously control the Cl− content in amphibole and imply that Cl− substitutes for OH− only in the ferro-paragasite or ferro-hastingsite component. Based on these structural considerations on Cl-amphibole, Cl− variations in the zoned amphibole from the Ramnes cauldron were interpreted. The zoning were developed under different fluid conditions in chemistry and temperature.

窒素上にエチル基,プロピル基またはイソブチル基を有するピペラジンテトラオンをアセトニトリル中で高圧水銀灯を用いて光照射するとγ水素引き抜きを経由して分子内酸化還元生成物および環化生成物が得られた。この結果より、この複素環化合物のカルボニル基はケトンやイミドのカルボニル基と同様の光反応性を示す事が明らかになった。また上記の環化反応は炭素と酸素の間の結合生成をともなう環化反応であり、これまでに例のない新しい型の環化反応である。窒素上に二個のアルキル基を持つイミダゾリジントリオンを種々のオレフィン存在下、ベンゼン中で光照射したところ、いずれの場合もオレフィンとの2+2付加物(オキセタン)が主生成物として得られた。イミダゾリジントリオンはスチルベンに対しても光付加してオキセタンを与えるが、この反応においては吸光係数から考えてイミダゾリジントリオンではなくスチルベンが光を吸収していると考えられる。このように、オレフィンの励起によるオキセタン生成はきわめて例が少なく、興味深い結果である。

Recovery from work today seems to be crucial for health care employees’ health, so it is important to uncover ways how to facilitate and improve adequate recovery from work. Focusing on the recovery concept of detachment from work, this study investigated associations between detachment after work and during work breaks and individual health among health care employees from a general hospital in the Netherlands. An online cross-sectional survey study was conducted comprising a sample of 368 health care employees of different departments. Controlling for demographics in hierarchical regression analyses, results showed that when health care employees experienced more cognitive detachment after work, they reported less concentration problems. Second, when employees experienced more emotional detachment after work, they reported less feelings of emotional exhaustion, less depressive feelings, and less sleep problems. Finally, in case employees experienced more physical detachment after work, they reported less concentration problems, less feelings of emotional exhaustion, less sleep problems and less physical health problems. No significant associations were found for detachment during work breaks. In conclusion, findings add to current recovery research showing that detachment after work is an important predictor for health care employees’ health.

<p>&nbsp;&nbsp;&nbsp;&nbsp;The purpose of this study was to clarify the relationship between running distance over an 8-month period and both 5000 m running performance and aerobic capacity (VO<sub>2</sub>max, VO<sub>2</sub>VT, running economy). The 8-month study period was divided into two segments of 4 months each. It was found that long-distance athletes could run 5000 m in about 15 min 30 s. The analysis also confirmed the following: (1) athletes that ran longer distances in the 8-month period had better 5000m times; (2) they had higher VO<sub>2</sub>VT; and (3) athletes whose distances were longer in the first half of the study period had better VO<sub>2</sub>VT and 5000m records in the second half of the period. The anaerobic threshold reached a higher level in runners with greater training distance, resulting in an improvement in race results. Furthermore, based on the fact that the distance run in the first four months effects on VO<sub>2</sub>VT and 5000 m running times in the latter four months, this study demonstrates the possibility of training effects occurring after a certain latency period. The results implicated that it was important to track running distances as an indicator of race performance.</p>

This paper deals with the historical development of catholic child care institution in Kyusyu. In the early Meiji period, Urakami child care institutions were built in Nagasaki. After the middle Meiji period, institutions continued to be built in various district. But, in war time, priests and sisters, they were foreigners, were confined. So institutions were hard to be managed. After the War, new institutions were built for the war orphan. The institutions that were already built before the War were also reformed and expanded. Some institutions merged and some were abolished. The institutions were reorganized. The characteristics of Catholic child care institutions were self-sufficient life by working on farm. Sisters worked on farm without reward. Medical institutions had relations with other institutions. So they changed. This paper proves the roles of Catholic child care institutions in the developing of social welfare in Japan.

石狩川は, 1975年8月23日に北海道に上陸した台風6号がもたらした豪雨によって増水し,下流部においては溢水した.筆者は,この洪水期間に石狩川水系内の6地点で水質調査を行い,増水時の水質特性および水質成分の流出機構について考察した.結果は以下のように要約できる.(1)懸濁態成分濃度は流量の増加とともに高くなり,最大値は空知川豊橋でSS4,500mg/1, COD (Cr) SSで266mg/1を観測した.主要無機成分の濃度は,流量の増加とともに減少したが,汚濁関連成分(BOD,硝酸イオンなど)は増水時に増加するなど特異的な変化を示した.(2)増水時においても主要無機イオンの構成には大きな変化はなかった.しかし懸濁物質はシルト・粘土成分の割合が,また有機物質は生物難分解性の割合が高くなるなどの変化が認められた.(3)洪水時の水質成分の流出特性から,水質成分の供給源を無制限供給型(懸濁成分),一定量供給型(主要無機成分),環境一時蓄積型(BOD,溶解性有機物質,硝酸イオン等)に分類できた.(4)洪水期間の水質成分流出負荷量を年間総流出負荷量と比較し,懸濁成分の割合が他の成分より著しく高く,SSでは82.5%に達することを明らかにした.
