  • The general properties of the NCBs, divided into A and F types according to their spectral types, have been presented. The evolutionary status of the F type near-contact binaries are closer to that of the contact systems, i.e., W UMa type binaries, if it is assumed that the evolution of the NCBs is governed by the thermal relaxation oscillation theory. The mass-radius relation, mass-luminosity relation and H-R diagram of the NCBs provide that the A type NCBs suffer from more active mass transfer than F types. The components of the NCBs ar still in main-sequence like W UMa type stars and their two components lines parallel to the ZAMS.

  • 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.

  • The purpose of this study was to construct and test a social relation model of youth school adjustment, based on Hirschi's social bonding theory and the previous findings in the area of youth school adjustment. The social relation model included parent-child relation, peer relation, and teacher-student relation variables. The sample consisted of two groups, 494 adolescents: 351 high school students and 143 adolescent residents at the shelter for runaways. For data analysis, descriptive statistics, correlation analysis, and multiple regression analysis were performed. The main finding was that the social relation model of youth school adjustment was significant in explaining the general school adjustment and academic performance. Specifically, the better relations with parents, peer, and teachers, the higher the degree of youth school adjustment. Among the significant variables, teacher-students relation was the most important variable. Based on these results, this study provided some practical suggestions to effectively enhance the relations with teachers, peer, and parents.

  • 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.

  • Bell's palsy is an acute-onset unilateral peripheral facial neuropathy. For patients with sequelae of facial paresis, the successful rehabilitation of fully edentulous arches is challenging. This case report described the treatment procedures and clinical considerations to fabricate complete dentures of a patient who showed unilateral displacement of mandible, unilateral chewing pattern and parafunctional jaw movement due to sequelae of Bell's palsy. Gothic arch tracing was used to record reproducible centric relation and lingualized occlusion was performed to provide freedom to move between centric relation and the patient's habitual functional area in fabricating satisfactory dentures in terms of function and esthetics.
