For efficient use of sunlight, the light-harvesting core antenna (LH1) and the reaction center (RC) form a supramolecular complex (LH1-RC) in photosynthetic bacteria. We determined the crystal structure of a LH1-RC complex from a purple bacterium, Thermochromatium tepidum. The structure reveals that the RC is completely surrounded by 16 αβ-heterodimers. Calcium ions are bound at the periplasmic side of LH1. 32 bacteriochlorophyll and 16 spirilloxanthin molecules form an elliptical assembly in LH1. The pigment geometry involved in the absorption characteristics and excitation energy transfer is determined. In addition, ubiquinone channels and lipid molecules are observed in the complex.

本研究の目的は,親への愛着を測定する尺度を作成し,親への愛着がストレス状況における適応過程へ与える影響について検討することであった.Brennan, Clark & Shaver (1998) は愛着を不安と回避によってとらえられるとしたことから,本研究では親への愛着をその2側面からとらえる尺度作成を試みた.研究1において,親への愛着,自己受容,親子関係からなる質問紙に回答を求めた.親への愛着は愛着不安と愛着回避の2因子が得られ,その信頼性と妥当性が確認された.研究2では,学校間移行という環境移行に焦点をあて,親への愛着の適応過程に及ぼす影響について縦断的に検討を行った.2回の調査において,親への愛着,自尊感情,孤独感,大学生活不安からなる質問紙に回答を求めた.その結果,愛着不安高群の方が愛着不安低群よりも,第1回調査時期と第2回調査時期における孤独感と対人関係不安の差が大きかった.このことより,親への愛着不安の低い方がストレス状況における孤独感と対人関係不安を緩衝していることが示唆された.

The purpose of this study is to examine the changes in the emotions that took place in the pupils nowadays as compared to the pupils more than 10 years ago, the causes for such changes and future educational implications. Data were collected through interviews with veteran teachers. Subjects were 68 teachers from six elementary schools and six high schools, most of whom had over 15 years of experience in instructing and caring for pupils. Firstly, a simple questionnaire was administered on the subjects to determine the changes in the emotions between the pupils nowadays and the pupils in the past. The following six aspects of emotions were examined, anger, sadness, joy, fear, surprise and fun. Next, Several teachers in each school were interviewed as a group by the first author. They were asked to respond to the following questions: (1). What are the characteristics found in the emotions expressed by pupils nowadays? (2). What contribute to such characteristics? (3). In terms of educating the pupils, what should the schools do to help pupils better develop their emotions? From the interviews, basing on the teachers' daily observations of pupils, we could conclude the characteristics of the pupils' emotions as follows. (1) Pupils nowadays were more likely to feel angry than pupils in the past, whereas the former were less likely to have and express sadness, joy, fear, surprise and fun than the latter, (2) The characteristics of the emotions among pupils were mainly determined by parents and culture, (3) Group activities, such as, field study and athletic club, would have a positive impact on the pupils' emotional growth.国立情報学研究所で電子化したコンテンツを使用している。
