This paper proposes a dynamic-tiling-based bandwidth-efficient (DTBE) virtual reality (VR) streaming scheme. We consider 360-degree VR contents with multiple view points such as the front, back, upper, and bottom sides. At a given time, the focus of a client is always bound to a certain view among multiple view points. By utilizing this perspective, under our proposed scheme, tiles with high encoding rates are selectively assigned to the focused view where multiple view points consist of multiple tiles with different encoding rates. The other tiles with low encoding rates are assigned to the remaining view points. Furthermore, for reducing view adaptation delay, we design a novel rapid view adaptation mechanism that selectively delivers an I-frame during view point updates by using frame indexing. We implement the proposed scheme on a commercial VR test bed where we adopt the MPEG media transport (MMT) standard with high-efficiency video coding (HEVC) tile modes. The measurement-based experiments show that the proposed scheme achieves an average data usage reduction of almost 65.2% as well as average view adaptation delay reduction of almost 57.7%.

Purpose: To describe the psychosocial adaptation, physical disability and social support, and to examine whether the physical disability and social support influence the psychosocial adaptation of women with Rheumatoid Arthritis(RA). Method: This survey was conducted with 102 women diagnosed as RA using a structured survey tool between April 12th and 30th 2004. Results: The Physical disability ranged from 0 to 51, the average was 9.89(${\pm}12.15$), appearing that less severe than previous studies. The social support ranged from 29 to 168, and the average was 91.73(${\pm}31.44$). The age, marital status, and monthly income were associated with patient's perceived social support. The psychosocial adaptation ranged from 77 to 186 and the average was 132.12(${\pm}24.13$). Entering physical disability and social support into the model significantly improved the prediction of psychosocial adaptation: 45.1% of the variance of psychosocial adaptation was attributed by the physical disability (Beta=-.325) and the social support (Beta=.204). Additionally, the religion (Beta=.231) and monthly income (Beta=.381) were significant predictors of the psychosocial adaptation. Conclusions: (1) Programs to improve physical disability of the clients are needed. (2) Marital status and age should be considered when the programs are developed. (3) More social support should be provided to the women with RA. (4) Adequate financial support is essential for the psychosocial adaptation of women with RA.

Objectives : The purpose of this study was to examine the satisfaction level of students with a job tour program and their major and their adaptation to their major in an effort to provide some information on student guidance and the improvement of dental hygiene education. Methods : The subjects in this study were 269 freshmen to find out their views of job tour and the relationship of their general characteristics and motivation of major choice to satisfaction level with their major and adaptation to the department, t-test and one-way ANOVA were carried out. And correlation analysis was made to look for connections among major satisfaction, major adaptation and satisfaction with job tour. Results : 1. As for the choice of major, the biggest group of 128 students (47.6%) made a decision on their own. 2. In regard to satisfaction level with their major, the freshmen got $3.55{\pm}0.67$, and the sophomores got $3.36{\pm}0.66$. There was a significant difference according to academic year(p<0.05). 3. Concerning the links between motivation for major choice and major satisfaction, the students who chose their major in consideration of their own aptitude or personality got the highest marks of $3.96{\pm}0.64$(p<0.05). 4. As to satisfaction level with the job tour program, they were most satisfied with field trip($4.03{\pm}0.74$). 5. Regarding the correlation among major satisfaction, major adaptation and satisfaction with the job tour program, there was a significant correlation among all the variables(p<0.01). Conclusions : The students who gave priority to their own aptitude and personality in choosing their major were more satisfied with their major and were better adapted to that. Therefore it's required to consider how to boost the satisfaction level of students with their major and their adaptation to that.

Given the evolving nature of the family unit, a large number of children are being left unsupervised after school. The purpose of this study is to understand the adaptation ability and emotional capacity of these children. To achieve this objective, we investigated the different characteristics of 708 middle-school students in Seoul, dividing them into two categories adult-care children, for whom adults provide care after school, and self-care children for whom no adult supervision was present. In particular, we examined children's adaptation to the school environment and possible self-consciousness difference between self-care and adult-care children, in consideration of their family characteristic; divorced, separated, widowed parent, remarried parents, ordinary families. The results showed that self-care children tend to have a higher rate of shame-proneness and guilt-proneness compared to adult-care children. Furthermore, self-care children exhibited lower school adaptation rate than adult-care children. There was no significant difference in schoolmate relationships between the two groups. In relation to specific family structures, children from reorganized families showed no significant differences in school adaptation and self-conscious, while self-care children from ordinary families revealed low school adaptation and high self-conscious characteristics. The results of this study are critical in the effective analysis and understanding of children's adaptive and emotional behaviors arising from changes in their family structure.

Although Korean international students/scholars are among the largest groups of international students/scholars on most campuses in the United States, little is known about what types of demands their families face and how they adapt successfully in the face of demands. The purpose of this study was to explore family resilience, which consists of family demands, capabilities, and adaptation, perceived by Korean international student/scholar families, being theoretically guided by the Family Adjustment and Adaptation Response (FAAR) model. Data were collected through face-to-face interviews with couple informants. Following procedures of theory-based content analysis, data were analyzed using key FAAR concepts. Findings showed that most informants reported normative types of family demands such as hardships due to childcare; primary family capabilities were "maintaining social integration," "affective and instrumental communication," and "family cohesiveness," and "nurturance, education, and socialization" was the primary family adaptation mode. New categories under family capabilities, "religious commitment" and "transnational family support" were developed. The results suggest that there is a unique set of family capabilities that contribute to the successful adaptation of Korean international student/scholar families. Implications and limitations are discussed.

Purpose: The purpose of this study is to examine the influence of laughter therapy programs on middle school students' happiness, self-esteem and school life adaptation. Methods: In total, 60 students (Experimental group= 30. Control group=30) were recruited to answer a self-administered questionnaire. The questionnaire was composed of questions about general characteristics, happiness, self-esteem and school life adaptation. The experimental group participated in a 45-minute laughter therapy program once a week for eight weeks, while the control group did not. Results: The scores of happiness(t=-4.68, p<.001), self-esteem(t=-3.38, p=.001), and school life adaptation(t=-3.76, p<.001) in the experimental group got significantly higher than the control group. Conclusion: Based on this study results, laughter therapy programs should be applied to improve happiness, self-esteem, and school life adaptation of middle school students.
