Purpose: The purpose of this study was to evaluate the association among of Activity of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), depression and isolation in disabled people. Method: The subjects consisted of 761 disabled people in Korea. Data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson's correlational statistics. Results: There were significant differences in age, cause of disability, type of disability, degree of disability, education, job, perceived health condition, and economic status between disabled people with high and low levels of ADL and IADL. Depression showed significant differences in type of disability, degree of disability, education, job, perceived health condition, and economic state; isolation showed significant differences in age, cause of disability, type of disability, education, job, residence, perceived health condition, and economic status. A significant association was identified between depression and isolation (r=.69, p<.001). Conclusion: There was a high incidence of depression in disabled men with high levels of isolation and ADL and IADL dependence. An effort to increase disabled people's ADL, IADL, and independence levels is needed, and nursing interventions should be designed and tested to increase their community involvement and decrease the sense of isolation and depression.

Purpose: The purpose of this study was to investigate the factors associated with social isolation in older adults using a senior welfare center. Methods: This study was a cross-sectional survey. Data was collected from June to August 2006 using a questionnaire. A total of 248 older adults responded. Results: About one third (34.9%) of participants responded they felt socially isolated. There were statistically significant differences in living, religion, family and belongingness social support, loneliness, depression, family function, perceived health status, and number of chronic illnesses between socially isolated and non isolated groups. However, factors influencing social isolation were family function (OR=0.954, CI=0.926-0.982), loneliness (OR=1.042, CI=1.002-1.083), depression (OR=1.041, CI=1.002-1.081), and number of chronic illness (OR=1.657, CI=1.153-2.382). Conclusion: We found that some older adults were feeling socially isolated even though the senior welfare center was a good place to meet people. The findings of this study indicated that older adults suffering from social isolation need special attention and may benefit from interventions which promote health and social interactions. Further studies are needed to develop and evaluate an intervention program for this population.

The Purpose of this study is to explain marital power processes perceived by Korean urban husbands. To do the task, this study examined the possibility of classifying the power processes and the effect of resources by using resource theory and normative resource theory . The main results were as follows. 1) Power precesses are classified into five factors, such as, 'induction'. 'isolation' quarreling' 'carelessness' and 'withdrawal of love'. Induction, which makes control attempts by using verbal, indirect communication strategies, is proved to be the most factor. 2) Power resource variables are proved to be significant in their effects on the power processes. That is, objective are proved to be significant in their effects on the power processes. That is , objective resources are influencing on 'induction' and 'isolation' behavior and subjective variables are influencing on the other control attempts, Thus, it is found that including subjective variables as well as objective ones is very important. Above all, that the concept of the centrality of patriarchy is supported to be an appropriate concept for the study on the marital power processes i8s a fruitful result in research. But the variances explained by resource variables are relatively small. It is suggested. therefore, further study should include more significant subjective resource variables.

The purpose of this study is to investigate children's perceptions of their own peer status and the variables that affect the perception. Four hundred boys and girls in grades five and six participated in this study. The participants were sampled from elementary schools located in two cities in Cheon-buk Province. Out of the 400 self-report questionnaires filled by the participants, 380 were used for the data analyses. The methods of analyses included basic descriptive categorical analysis (frequencies, means, percentages) as well as t-test, one way ANOVA, and multiple regressions. To summarize major findings from the analyses; first, a significant difference was found in children's aggression by father's job and mother's age, in children's popularity by school GPA, father's education, mother's education, and fathers job, and in children's isolation by father's age, father's education, mother's education, and father's job. Second, children's aggression was significantly dependent upon self-esteem, loneliness, family harmony, and family communication. Children's popularity was related with school grade, name satisfaction, body satisfaction, self-esteem, number of close friends, loneliness, family harmony family communication, parental love and acceptance, and perceived closeness to mother. Children's isolation was significantly associated with school grade, body satisfaction, self-esteem, number of close friends, loneliness, family harmony, family communication, parental love and acceptance, and perceived closeness to mother Third, according to the multiple regression analyses, it was found that highly aggressive children tend to report less family harmony, more loneliness, and a larger number of friends. Also, highly popular children tend to report less loneliness, larger number of friends, strong family harmony, and higher academic achievement. On the other hand, highly isolated children tend to perceive weak family harmony, more loneliness, and lower body satisfaction. Lastly, the overall peer status indicator depended significantly on family harmony, loneliness, self-esteem, academic achievement, body satisfaction.

Patients diagnosed with cancer face mental problems such as alienation, isolation, anxiety about death and fear, recovering from psychological difficulties. In this study, a forest healing program was provided for cancer patients to recover from psychological stress, depression, social isolation and self-esteem caused by cancer and changes in salivary cortisol through psychological and emotional recovery were measured. From September 19 to November 28, 2017, a forest healing program composed of a total of 10 sessions, two hours per session was provided for 12 cancer patients in the Forest of Taegyo located in Yongin. Psychological tests were performed with Social Adaptation Self-evaluation Scale (SASS), Korean-version Perceived Stress Scale (PSS) and Beck Depression Inventory (BDI) and the collected data were analyzed with the SPSS 18.0. The salivary cortisol level was measured along with the psychological tests and were analyzed by a specialized testing agency. The results of the analysis showed that the pre- and post-assessment score of SASS was 29.17 and 25.92, respectively, and that the pre- and post-assessment score of PSS was 30.50 and 23.92, respectively. The pre- and post-assessment score of BDI was 41.00 and 34.83, respectively, which showed significant differences. In addition, the pre- and post-assessment level of saliva cortisol was 3.13 and 1.68, respectively, showing a significant decrease. In short, the forest healing program was found to be effective in reducing physiological changes caused by social isolation and stress due to the emotional and psychological difficulties that the subjects who were diagnosed with cancer and were recovering from it have. In the future, it will be necessary to develop and implement a forest healing program by conducting a forest healing requirement survey on cancer patients.

This paper proposes reversible data hiding using minimum/maximum preserved overflow/underflow avoidance (MMPOUA). The proposed MMPOUA algorithm consists of three main steps. These steps include the minimum (or maximum) pixel fixing, pixel squeezing, and pixel isolation. The aims of pixel fixing are to keep the minimum (or maximum) pixel of a host block unchanged and prevent the occurrence of overflow/underflow. Both the pixel squeezing and pixel isolation supply hiding storage while keeping the amount of distortion low. The proposed method can avoid (or significantly reduce) the overhead bits used to overcome overflow/underflow issues. At an embedding rate of 0.15 bpp, the proposed algorithm can achieve a PSNR value of 48.52 dB, which outperforms several existing reversible data hiding schemes. Furthermore, the algorithm performed well in a variety of images, including those in which other algorithms had difficulty obtaining good hiding storage with high perceived quality.
