This study examines 2014 National Survey on Older Koreans (10,279 persons aged 65 or above) to understand social networks among older Koreans. In order to classify the types of social relationships, the latent profile analysis is conducted based on such structural aspects of social networks as network size, frequencies of contact, and closeness. The results show that older Koreans can be categorized into 5 distinct social network types: disengaged (11.6%), ritual-family-focused (17.7%), close-family-focused (23.6%), close-restricted (28,4%), and diverse (18.8%). Characteristics by each social network type are compared and multinominal logistic regression analyses are applied to figure out the influencing factors of social network type. Older persons with disengaged social network ties tend to be overwhelmingly female, living alone, old-old, and of low socioeconomic status. On the other hand, older persons with diverse social network ties tend to be young-old and had highly-ranked jobs in their mid-life. Spouse/children are the focal point of social relationships in both ritual-family-focused and close-restricted social network. However, the proportion of men is higher in the close-family-focused type than in the ritual-family-focused. Older Koreans with close-restricted social network ties tend to be female, uneducated, and have engaged in agricultural and allied activities. This study discusses the implications of its findings and how research in this area should develop in the future.

The purpose of this study was to investigate the effect of exercise preconditioning (EPC) on nerve growth factor (NGF), synapsin I, and choline acetyltransferase (ChAT) in the hippocampus of rats subjected to social isolation (SI). We randomly assigned four groups of male Sprague-Dawley (SD) rats (n=32) to the following treatments: GC: group housing control; IC: isolation control; GE: group housing exercise; IE: isolation exercise (n=8 each group). The rats underwent EPC 5 days a week for 8 weeks, and the speed of the treadmill was gradually increased (grade $0^{\circ}C$). After EPC, they were immediately subjected to SI for 8 weeks. The results showed that the protein levels of NGF, synapsin I, and ChAT in the hippocampus were significantly decreased in the IC group (p<0.05) compared with the GC group. However, these protein levels were significantly higher in the IE group (p<0.05). These results show that EPC may buffer the decline of function in the hippocampus by ameliorating the reduction in NGF, synapsin I, and ChAT induced by SI.

The present study examined patterns of co-occurrence between DSM-5 posttraumatic stress disorder(PTSD) symptoms and posttraumatic growth(PTG) among Korean populations(n= 860). Latent profile analysis was used to identify subclasses and suggested that the 3-class model fit best: (1) Low PTSD/Mild PTG group (2) Low PTSD/High PTG group; (3) High PTSD/High PTG group. Class membership was predicted by demographic variables, social isolation, and frequency of traumatic experiences. Classes also differed with respect to self-destructive behaviors(binge eating, non-suicidal self-injury, and problem drinking). These findings contribute to future research about the coexisting patterns of PTSD and PTG, and to identify high-risk individuals who suffer from trauma-related problems in clinical practice.

This research is to study the economical, psychsocial, physical pains of the elderly mens living alone and the process being out of the isolated life. From this, we expect to propose a supportive program to help the living alone of the elderly mens. Six of the elderly mens living alone joined this research and the hermeneutical grounded theory methodology was applied to interpret it. Data were collected by the depth interview and various written records and they were analyzed by Rennie(2007)'s methodology. We could construct 13 categories by analyzing and categorizing meaningful units of the data. The core theme of the living alone experience was presented as "Accepting self-existence forgotten in the swamp of isolation and preparing for the blessed death." Based upon the research outcomes, we suggested a social supportive program considering the elderly men's characters and a way to improve the accessibility to the therapy system for the elderly mens living alone and the need for a meaning therapy.

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 performance evaluation of a conventional Wave Resonator at the entrance of harbors against solitary wave has been performed using 3D numerical wave flume. A wave resonator has been designed for the attenuation of the transmitted wave energy by trapping the short periodic incident waves only. In this study, however, the controlled performance of the wave resonator by its various widths has been numerically investigated for solitary waves. Source distribution method based on the Green function and the 3D one-field Model for immiscible TWO-Phase flows (TWOPM-3D) using 3D numerical wave flume were used for the short-periodic waves and the solitary waves, respectively, and these models were verified through the comparisons with the previous experimental and numerical results by other researchers. It was confirmed that the wave resonator is effective enough to control the solitary waves as well as the periodic waves when it compares with the case of no resonance system. Further, it was found that there is the optimal width of a wave resonator to attenuate the target solitary waves.

The animation is expressed by fusing the character's aesthetic feature and action in the entire structure and such creation of the character is needed to approach with understanding its socio-cultural background and dramatic structure. This study has started for the reason that there is a need of making an animation character based on reality, as well as to develop a individual character and narrative skill at the same time. In this study, analyzing through the DSM-IV (Diagnostic and Statistical Manual of Mental Disorders) by the American Psychiatric Association, APA), I have been able to come to a conclusion in which the character's personality is presented more exaggeratingly than its ordinary tendency. So it is used as a means to occur a dramatic motive-induction and probability. Futhermore, applying the same condition of the personality disorders to the animation character has changed the narrative development and it showed a result that even the character is not having the problem of personality disorders, it shows the nature of personality disorders-like is being appeared exaggeratingly or increasingly.

Children who have problems in interacting appropriately with others typically have significant social skills deficits. Social skills training has become a primary intervention to improve the appropriate peer relationship or peer acceptance. Many social skills training programs have been designed and implemented on socially isolated children, however the findings from many studies investigating the effect of social skills interventions are various. The first purpose of this study was to verify the effectiveness of interventions by using quantitative method of meta-analysis. Second, it was to review a various research in detail. Third, it was to provide the basis of planning a social skills training program. For these purposes, findings from 26 studies investigating the effects of social skills interventions for 624 socially isolated children (5-12 years) were analyzed. The result of this study were the following : The pooled overall mean effect size(ES) was 1.11. On average, the pooled mean effect size(ES) according to the different research variables was large, meaning that the social skills intervention had a great effect and was socially important and necessary for socially isolated children. It would be recommended that social skills programs include appropriate target behaviors through multidisciplinary assessment process. This program should mainly focus on the improvement of prosocial behavior skills as well as reducing problem behaviors. For preschool children, over 50 minutes per session, two to three sessions per week, for a total of total over 20 sessions would be ideal. Posttest and follow-up need to perform for generalization and maintenance. Content of the program should be tailored to the developmental level as well as the interest level of the children.
