Purpose: The purpose of this study was to understand the adjustment process of middle-aged people in Korea with hemiplegia after a stroke. Method: For this study, the grounded theory method was utilized. Results: After constant comparative analysis, the core category emerged as 'rebuilding the body which was ruined'. In addition, the causal conditions were 'restriction of physical function', and 'loss of roles'. The adjustment process consisted of the 'facing reality phase', 'overcoming depression phase', 'overcoming physical limits phase' and 'reestablishing roles phase' The main strategies in the facing reality phase were 'holding on to a glimmer of hope', 'getting away from the harsh reality' and 'facing up to the reality'. The main strategies in the overcoming depression phase were 'soothing oneself', 'Self-introspection' and 'restoring self-esteem'. In addition, the main strategies in the self-initiative overcoming physical limits phase was 'discovering personal strategies and striving to recover'. The main strategies in the reestablishing roles phase were 'reestablishing a parents' role', 'reestablishing a spouse's role' and 'reestablishing social roles'. Conclusion: In conclusion, even though many middle aged stroke patients remained in the depression phase, most of them who overcame depression strived to conquer physical limits on their own initiative.

Online rumor creates psychological stress and image loss for victims. Prior studies related to online rumor did not consider the online environmental factor, despite the fact that online rumor occurs in the online space. Therefore, this study tried to investigate the influence of online characteristics on online rumor. This study considered perceived anonymity, lack of social presence, and perceived dissemination as online characteristics. We established and demonstrated a research model in which online characteristics affect online rumor behavior through attitude toward online rumor. This study obtained the sample of 201 social network users based on the survey and verified the research model using PLS tool. The results provided that perceived anonymity and perceived dissemination influenced online rumor behavior through attitude toward online rumor. On the other hand, lack of social presence was not significant. The findings of this study provide the fact that an individual's online rumor behavior can be caused by online characteristics. This study suggests that we pay attention to the role of perceived anonymity and perceived dissemination for online rumor behavior.

One of the difficulties of female-headed families face is economic hardship. Low-income single mothers work long hours, become isolated and feel burdened for dual roles. And many of them don't have relatives to share parenting roles. As a result, children of low-income female-headed families are easy to be neglected and left to form a delinquency-prone group in neighborhood. Traditionally, it has been viewed that children in female-headed families have problems due to the loss of father role. However, study indicates that these children can adjust well if the relationship between mothers and children is consistent and adequate. An Intervention program for low-income female-headed elementary children was developed and delivered in two community social welfare centers. The purpose of the program is to raise self-esteem. Two goals were 1) management of daily living habits and 2) improvement of family relations. Social workers maintained contact with mothers to talk about children's behaviors and to prompt hugging and touching. In addition, workers helped children to form good relationships with peers and school teachers. Children were satisfied with the program. Their family relations were improved statistically significantly after the program(wilcoxon signed rant test z=-2.934 p<.05). However, their self esteem were not improved significantly (wilcoxon signed test z=-1.173 p>.05). Qualitative analysis of each children were also discussed. The implications of the study are the followings: Intervention programs need to be delivered separately for low-grade and high grade elementary children because they have different developmental needs. The program also need to include education on sex and marriage as well as aggression reduction. Society needs to provide more support to single mothers for their personal and parenting needs.

Cardiopulmonary arrest has long been accepted as an unquestionable definition of death. An advent of cardiopulmonary resuscitation and artificial ventilation along with the development of organ transplantation has prompted the emergence of the concept of brain death. The criteria for brain death are based mainly on the clinical examination of coma, apnea and total loss of brain stem function. Although organ transplantation by donor brain death has increased in Korea over recent years, there is still a substantial shortage of donor organs compared to the demand. Improvement of government policies and changes of social culture for organ donation are needed for the activation of organ transplantation by donor brain death. Pediatricians have an important role for the search of potential donors in cases of brain death and optimal medical care for successful organ transplantation.

Recent government policies are increasing interest in zero-energy housing, a building that minimizes energy consumption (90% reduction). As the importance of building passive performance is emphasized, the role of insulation is increasing as a way to reduce indoor heat loss in order to minimize the use of cooling and heating energy. There are two main types of insulation. Organic insulation is widely used for various construction structures such as construction and industrial due to some merits such as the convenience of construction and construction cost. However, it has been pointed out as a main cause every time a fire accident occurs, Jecheon Sports Center', the fire damage of buildings caused by the use of organic insulation materials is expanding to social problems, so it is urgent to research on nonflammable inorganic insulation materials.

Cybercrime is a significant threat to Internet users, involving crimes committed using computers or computer networks. The landscape of cyberspace presents a complex terrain, making the task of tracing the origins of sensitive data a formidable and often elusive endeavor. However, tracing the source of sensitive data in online cyberspace is critically challenging, and detecting cyber-criminals on the other hand remains a time-consuming process, especially in social networks. Cyber-criminals target individuals for financial gain or to cause harm to their assets, resulting in the loss or theft of millions of user data over the past few decades. Forensic professionals play a vital role in conducting successful investigations and acquiring legally acceptable evidence admissible in court proceedings using modern techniques. This study aims to provide an overview of forensic investigation methods for extracting digital evidence from computer systems and mobile devices to combat persistent cybercrime. It also discusses current cybercrime issues and mitigation procedures.

Houttuyniae Herba is widely used as a cosmetic for enhancing hair growth, and study on promoting mouse hair growth has also been reported. However, studies on the effects of the Houttuyniae Herba on dermal papilla (DP) cells, which play an important role in hair growth, are not well known. For this reason, we studied the effect of Houttuyniae Herba on DP cells. The strong antioxidant activity of Houttuyniae Herba was confirmed by ABTS assay. In the MTS assay, cell viability was reduced to 94.5% in DP cells by treatment of 2 mg/ml concentration of Houttuyniae Herb and cytotoxicity was not observed at 1 mg/ml concentration. The mRNA expression levels of Bone morphogenetic pretein (BMP6), fibroblast growth factor 7 (FGF7), FGF10, and ${\beta}$-galactosidase genes, which are involved in hair growth cycle and hair loss induction, were measured by quantitative RT-PCR after Houttuyniae Herbtreatment. Houttuyniae Herb did not significantly affect mRNA expression of BMP6, FGF7, FGF10, and ${\beta}$-catenin, which are important factors for regulating the hair cycle, including type 1 $5{\alpha}$-reductase. However, mRNA expression of type 2 $5{\alpha}$-reductase, the major cause of male hair loss, was significantly reduced to 56.1% by treatment of Houttuyniae Herbtreatment. Taken together, these results suggest that the Houttuyniae Herbtreatment can help to treat lair loss through removing free radicals and suppression of the expression level of type 2 $5{\alpha}$-reductase in DP cells.

Activity theory explains that the old people participate in social activity as a role-substitute from loss of roles given by work and family. It is possible to enhance their life satisfaction through these activities. Based on this activity theory, this study aims at explore the role substitute of voluntary activities and to analysis whether volunteering commitment has an effect on life satisfaction. Data were collected by using survey questionnaires to the elderly over 55 years old who participated in voluntary activity at 25 Volunteer Centers in Seoul. The Activity theory was operationalized by job or joblessness, family type, achievement type obtained through voluntary activity The results are as follows. (1) Job or joblessness has effect on the activity frequence and activity time. (2) Social achievement after voluntary activity has effect on the duration only (3) And the family type did not have any effect. These three variables of activity theory do not have an effect on life satisfaction. The elderly volunteering commitment was explained by variables other than activity theory such as reward, health, education, sex. And the elderly volunteer's life satisfaction were affected by the family types and their economic status. These results imply that the Korean elderly voluntary activities could be expained partially by Activity theory. Also for these elder volunteers's life satisfaction, qualitative respects such as achievements through voluntary activity, and concerns and support by agencies are more important than the time they imput in voluntary activities.

This study analyzed the path through which elderly discrimination experience, sense of loss, and depression lead to suicidal ideation by verifying the influence of elderly discrimination experience on suicidal ideation and the mediating effect sense of loss and depression. The subjects of the study were a 1:1 in-depth interview survey of 400 elderly people aged 65 or older using stratified sampling methods by region and type of 31 city, county, and district the elderly welfare welfare centers(10 locations) in Gyeonggi-do. As a result, a total of 360 samples were finally analyzed. It was verified through frequency analysis, descriptive statistics analysis, correlation analysis, structural equation and bootstrapping analysis methods using SPSS 25.0 and AMOS 23.0. As a result of the study, first, it was found that the more the elderly experienced discrimination, the higher the suicidal ideation. Second, the effect of sense of loss was partially mediated on the effect of discrimination experience on suicidal ideation in the elderly. Third, the feeling of depression was found to play a partial mediating role between the experience of discrimination among the elderly and suicidal ideation. Based on the results of this study, policy and practical suggestions were made to alleviate the suicidal ideation of experiences of discrimination against the elderly and sense of loss and depression to prevent suicide among the elderly.
