근접촉쌍성을 분광형에 따라 A형과 F형으로 분류하여 각각의 물리적 특성과 진화를 조사하였다. 그 결과, 근접촉쌍성이 TRO 이론에 따른 진화 경로를 겪는다고 가정하면, F형이 A형에 비하여 더 접촉에 가까운 즉, W UMa형에 근접한 상태에 있을 가능성이 있음을 알 수 있었다. NCBs의 질량-반경 관계, 질량-광도 관계 및 H-R도를 조사하였는데 그 결과 A형이 F형에 비하여 질량교환이 활발할 것으로 생각된다. 근접촉쌍성은 ZAMS와 평행하게 나타나며 접촉쌍성의 진화 위치와 거의 일치하고 있다.

This study has been conducted to investigate the developmental changes of cambial initials and their derivatives in relation to the growing girth of tree in Diosypros kaki and Firmiana simplex. In D. Kaki and F. simplex with typical storeyed cambium, increase in the girth of camium occurred by radial anticlinal division in general, however occasionally the increase was companied by pseudotransverse division. The length of fusiform initials, vessel member, and sieve tube member remained relatively constant throughout the secondary growth but that of fiber showed general tendancy to increase with growing girth of tree. During the girth increase of tree, height and number of ray remained constant in D. kaki, however in F. simplex, height of ray markedly decreased while the number of ray per unit area more or less increased. The secondary ray was originated from the segmentation or division of the side or end of fusiform initials.

본 연구의 목적은 허쉬(Hirschi)의 사회유대이론과 학교적응 영역의 기존연구를 토대로 청소년의 학교적응에 관한 사회적 관계 모델을 제시하고 검증하는 것이다. 사회적 관계 모델에는 부모관계변인, 친구관계변인, 교사관계변인이 포함되었다. 연구 대상은 인문계 고등학교 재학생 351명과 전국 쉼터에 머무르고 있는 청소년 143명으로 총 494명이었다. 자료분석방법으로는 기술통계, 상관관계분석, 중다회귀분석이 사용되었다. 분석결과, 청소년의 학교적응에 관한 사회적 관계 모델이 청소년의 전반적 적응과 학업적 적응(성적)을 설명하는 데 유의미하다는 것이 밝혀졌다. 구체적으로는, 부모와의 관계가 좋을수록, 친구와의 관계가 좋을수록, 교사와의 관계가 좋을수록 청소년의 학교적응도가 높아지는 것으로 나타났으며, 이 중 가장 영향력있는 변인은 교사관계 변인이었다. 이러한 결과를 기초로 본 연구는 청소년의 학교적응을 높이는 방법으로서 교사 친구 부모와의 관계를 긍정적으로 변화시키기 위한 실제적 방안을 제시하였다.

This paper argues that the de se reading is a composite of the corresponding de re one plus the presupposition that there exists a strong epistemic relation between the object of attitude, linguistically realized as an anaphor, and the attitude-bearer, the referent of the anaphor's antecedent. Close examination of the relation between the attitudes de se and anaphora reveals that the notion de se, as currently understood, should be generalized to explain the choice of anaphors. A taxonomy of anaphors in terms of a general notion like presupposition provides further empirical support for the approach taken here.

This study aimed to identify the effects of contents, to find out the development approaches of promotion and contribute to increase the expectation on medical institutions and wills to use and improve the customer satisfaction on homepages of such medical institutions by analysis on the contents of hospital homepage. This research performed the frequency analysis, cross analysis, t-test correlation analysis, and multiple regression analysis and came to the conclusion. In accordance with the research results, since the university hospital homepages had more contents than the homepage of general hospitals and national and public hospitals, the university hospital homepage provided sufficient information to visitors and tried to satisfy the customers and activate the hospital promotion using the homepage contents. On the contrary, the homepage of general hospitals and national and public hospitals had insufficient contents and unique and differentiated contents were not sufficiently provided. On the basis of the results of this study, further study on the approaches to improve the contents of homepage of general hospitals and national and public hospitals will be of great help to activate the hospital promotion by increasing the average number of visitors and page views. Furthermore, it is required to make every endeavor for systematic management and operation and research on promotion using the homepage contents.

Seasonal variation in global transport calculated from an ocean general circulation model (OGCM) has been assessed through the comparison with observational estimates. The OGCM based on the GFDL MOM1.1 has honzontal grid interval of 10 and 21 verticle levels, and was integrated for 31 years forced by climatological wind stress, freshwater flux, and heat flux with restoring. General features of the world ocean circulation are well reproduced, which include the western boundary currents such as the Kuroshio and the Agulhas Current, the Equatorial Current system, the Antarctic Circumpolar Current, and the Weddell Sea gyres. Also well resolved is the remarkable seasonal variation in the depth-integrated flows in the northern Indian Ocean due to the monsoonal wind. Monthly variation is found to be dominant in the transport of the Antarctic Circumpolar Current through the Drake Passage in accordance with observational estimates. It has been shown that the mid-latitude depth-integrated flows obey the Sverdrup relation, except for some regions such as continental shelf regions where the interaction between stratification and bottom topography is critical.

Purpose: The purpose of this study is to provide preliminary data for alleviating nurses' job stress and support health promotion behaviors. Further, the study reviews the mediating effects of positive psychological capital and nursing work environment in relation to job stress and health promotion behaviors among nurses in a regional general hospital. Methods: A study survey was conducted from June 9 to 16, 2017. The subjects were current nurses working at a regional general hospital in D city. Analysis of a survey questionnaire from 147 participants was conducted. Results: Upon reviewing the mediating effects of positive psychological capital and nursing work environment in relation with health promotion behaviors and job stress, it was found that positive psychological capital (Z=-4.78, p<.001) and nursing work environment (Z=-4.17, p<.001) were significant mediators. Conclusion: As demonstrated through the results of this research, it is necessary to build programs to strengthen individual positive psychological capital and increase the practice of health promotion behaviors among nurses. It is also evident that a systematic approach is needed to improve the nursing work environment.

Purpose: This study aimed to grasp the correlation between communication ability, empathy, and interpersonal relations among nursing students, and to explore the mediating effect of empathy on the relation between communication and interpersonal relation in nursing students. Methods: Participants were 209 college students in the Department of Nursing at two universities. The data collection period was from October 1, 2019 to November 1, 2019. The questionnaire consisted of measuring tools for general characteristics, communication ability, interpersonal relation and empathy. SPSS/23.0 program was used. The analysis used descriptive statistics, Pearson's correlation coefficient, independent t-test, one-way ANOVA, multiple regression analysis, and Sobel's tests. Results: The communication ability was nursing major satisfaction (t=8.25, p<.001), and last year's average grade (t=7.29, p=.001). Interpersonal relationships showed significant differences in gender (t=2.51, p=.013) and nursing major satisfaction (t=10.99, p<.001). Communication ability and empathy (r=.37, p<.001), communication ability and interpersonal relation (r=.77, p<.001), empathy and interpersonal relation (r=.43, p<.001) showed a significant static correlation. In communication ability and interpersonal relation, empathy had a partial mediating effect (Z=2.97, p<.001), and explanatory power was 62%. Conclusion: To improve the communication ability and interpersonal relation of nursing students, it is necessary to develop a personalized and empathy-enhanced education program for each grade.

벨마비는 원인이 명확하지 않은 급성 말초성 안면 신경마비로 주로 편측으로 나타난다. 일부에서는 완전히 회복되지 못하여 안면 근육의 불완전 마비, 구축 등의 후유증으로 인해 하악의 편측 변위 또는 편측 저작 습관 및 부조화가 나타나며, 따라서 만약 무치악 환자에서 총의치로 수복한다면 더욱 세심한 주의가 필요하다. 본 증례에서는 벨마비의 후유증과 불안정한 하악 운동으로 인해 술자에 의한 중심위 채득이 어려운 무치악 환자에서 고딕아치 묘기법으로 재현성 있는 중심위를 채득하고, 중심위와 환자의 습관적인 하악 기능 운동 범위 간의 자유도 부여를 위해 설측 교합을 이용하여 총의치를 제작함으로써 기능 및 심미적으로 양호한 결과를 얻었기에 보고하는 바이다.
