The major electron transfer cofactors in photosystem II have been studied by pulsed EPR, pulsed electron electron double resonance (PELDOR) and laser excited spin polarized electron spin echo envelope modulation (ESEEM) methods, in non-oriented and oriented photosystem II membranes. Distances between radical pairs were determined trom the observed dipole interaction constants to be 27.3 A for P680-QA, 30 A, etc. with the error within 1 A. Angles between the distance vector and membrane normal was determined by orientation dependence of oriented membranes with the accuracy of 5˚ The results were compared with the recent structural data by X-ray analysis.

The purpose of this study was to explore the trends of research on MBTI (Myers-Briggs Type Indicator) and nursing students, and to suggest directions for nursing education geared to the needs of the future. The literature was searched using the National Assembly Library, Korean Studies Information Service System, DBPIA, Korean Medical database and National Discovery for Science Library to identify studies including MBTI personalty among nursing students. This study selected a total of 22 precedent studies regarding the investigation of MBTI personalty and nursing students. All studies were quantitative study and 63.6% of them were nonexperimental cross-sectional study. The most frequently selected category of variables was cognitive-perceptual related variables includes self-efficacy, self-eseem, academic self efficacy and etc. The most frequent MBTI personality type of nursing students was ISTJ (12.3%) and ESTJ (11.5%) was the second. Based on the findings of this study, longitudinal reasearch is recommanded on MBTI personality type and nursing specialty choice. Implications for teaching and learning strategies, and for using the results of MBTI in nursing students' career guidence are discussed.
