This study aims to identify subgroups of ageism among young adults of age 20-39, and to examine its relationship to perceptions of generational conflict and elderly welfare policy. Latent Profile Analysis(LPA) was applied on the data 'Survey on Age Integration and Generational Integration', which was executed by institute for Age Integration Researchof Ewha Womans university, and descriptive statistics and cross-tabulation analysis were performed to examine the socio-demographic characteristics of each subgroup. Then, regression analysis was performed to observe the effect of the subgroups on the perceptions of generational conflict and elderly welfare policy. The results are as follows. The resulting subgroups of ageism among young adults were 'compound perception on aging and active age discrimination', 'medium-level aging anxiety and passive age discrimination', and 'low-level aging anxiety and beyond age discrimination'. Subgroups of ageism affected both perceptions of generational conflict and elderly welfare policy, whereas social support only affected perception of elderly welfare policy. Based on the results, political implications, such as activation of education on perception on aging, expansion of generational exchange for age integration, and renewal of social atmosphere for intergenerational coexistence, which will promote social integration

The purpose of this study was to explore bullying among senior women at a senior center. Using ethnographic research technique, we examined the process in which members of the senior center engaged in and responded to bullying. Purposive sampling method was used to choose a senior center as the subject of this study. Within the center, 16 senior women participated in the study. In-depth interviews and participatory research methods were used to collect data. We analyzed the transcripts of the interviews based on the ethnographic analysis method presented by Spradley (1979). Themes that emerged from these participatory research and interviews include: members of the senior center creating loners, people being bullied causing damages to the group, taking actions to respond to bullying, and failing to solve the bullying problems. First, the victims of bullying became loners with no one to rely on through other members' verbal attacks, discrimination, isolation, and stopping the victim to use the senior center. Second, the victims were under attack but also caused troubles at the senior center and harmed others at the same time. Third, while engaging in bullying, senior women attempted to deal with bullying problems in many ways. These attempts include: avoiding the conflict, withstanding, attempting to mediating, and so on. Finally, bullying remained to be a recurring phenomenon at the senior center. New victims of bullying continuously appeared and the influence of bullying was felt not only within the senior center but outside as well. Based on the findings of this study, we suggest that practitioners and researchers take into account factors that affect bullying among senior women.

Although the rate of self-employment is high in Korean labor market and the rate gap between age groups is high, few studies have addressed on the effects of push factors on transition into self-employment across age groups. The goal of this research is to determine if push factors exert different effects on the self-employment decisions across age groups. There is interest in testing push hypothesis and pull hypothesis. The Korean Labor and Income Panel Study wave 6~11 is used to test this study's hypothesis. The main contribution of the paper is that in case of high unemployment, the probability of transition into self-employment increases. It is consistent with the push hypothesis. Many people are forced to become self-employed person due to the high rate of unemployment and limited occupational choice rather than the role of entrepreneurship. By age subgroup, the transition into self-employment of the ages of 30 and 49 is high. In addition, people at 40-49 years of age are more likely to become self-employed as a response of inadequate job opportunities. It provides the evidence that the self-employment is not a matter of special age group in that people in the 30 to 49 year old age group whose economic activities are vigorous move into marginalized labor market. Furthermore, it seems to be threatened the employment's stability of the prime age in that even people who are age 40-49 years of age are pushed into self-employment because of the recession.

This study was aimed at looking into and understanding child-rearing experience of mothers from multicultural families based on the grounded theory, one of the qualitative research methods. For this, twelve mothers from multicultural families were selected and data were collected through in-depth interviews with them and then analyzed through the open coding, axial coding and selective coding. The analysis suggested that main phenomena mothers from multicultural families experienced are the conflict of child-rearing and educational crisis, and the confused identity of parenting. These main phenomena had much to do with contextual factors such as economic hardship, lower level of the Korean language, cultural differences, prejudices and ignorance. The severeness of conflict and crisis of child-rearing and the intensity of identity confusion for parenting depended on arbitral conditions such as family bonds, positive expectation for the future of their children, and the help of supportive systems. Mothers were dealing with difficulties of child-rearing through action and interaction of resignation and denial, introspection and the intention to overcome difficulties, and the capacity building. As a result, mothers from multicultural families acknowledged that there is a limit to their position and roles they can play and tried to change in order to resolve problems related to their children, positioning themselves for more active lives in Korean society. Through discussion based on the findings of the study, this study can help better understand child-rearing experience of mothers from multicultural families and suggest several directions for future researches on multicultural families.

In this study, the bearing pressure on the rubble mound of a gravity-based harbor structure with an arbitrarily shaped bottom was targeted. Assuming that the bottom of the structure is a rigid body, the rubble mound was modeled as a linear spring uniformly distributed on the bottom that resists compression only, and the bearing pressure evaluation formula was derived. It was confirmed that there were no errors in the derivation process by showing that when the bottom was square, the derived equation was converted to the equation used in the design. In addition, the validity of the derived equation was proven by examining the behavior and convergence value of the bearing pressure when an arbitrarily shaped bottom converges into a square one. In order to examine the adequacy of the method used in the current design, the end bearing pressure for the pre-designed breakwater cross-section was calculated and compared with the values in the design document. As a result, it was shown that the method used for design was not appropriate as it gave unsafe results. In particular, the difference was larger when the eccentricity of the vertical load was large, such as in the case of extreme design conditions.

The purpose of this study is to develop and verify the Relational Self Scale(RSS). Based on the theoretical assumptions which relational self is multi-dimensional and constructed in social contexts, 10 categories with 102 items were yielded. In the process of content analysis, item analysis, exploratory factor analysis and correlation analysis by administering 102 items to korean adults, 31 items with 7 factors are extracted. The 7 factors are consisted of 'avoidance of relation', 'consciousness of others', 'agency', 'instrumental relation', 'empathy-care', 'perceived support from relation' and 'over-dependency to relation'. Next, Confirmatory factor analysis was conducted with 649 korean adults aged from 20's to 60's. The results of confirmatory factor analysis showed the RSS as a valid scale. The 7 factors of the RSS fitted well with men and women. The internal consistency of the RSS was proved to be acceptable. The latent mean analysis indicated that the relational self was not significantly different between men and women at 7 factors. Correlation analysis showed that the construct of relational self was significantly related to relational self-construal, self-esteem and attachment to parent and intimacy person. This study has implication in that relational self is defined and assessed as multi-dimensional construct, and that by administering RSS it is possible to evaluate distinctive korean people's relational self.

피부 노화는 피부와 피부 지지층 등의 광범위한 퇴행 과정을 말한다. 피부 노화의 원인은 흡연, 공해, 스트레스 등이 있지만, 그 중에서도 자외선(ultra violet, UV) 조사가 가장 큰 요인으로 꼽힌다. 반복적인 자외선 조사에 의해 진행되는 피부노화를 광노화라고 하며 그 가장 큰 특징으로는 콜라겐 섬유와 엘라스틴의 감소로 야기되는 주름을 들 수 있다. 본 연구에서는 제주에서 채집한 바위수국의 추출물 및 분획물의 항산화 및 자외선으로 인한 피부노화 예방(anti-photoaging) 효능을 확인하고, 활성물질을 분리하여 광노화 예방 효능과 그 메커니즘을 확인하였다. 실험에 사용된 바위수국은 범의귀과의 덩굴성 식물로 바위면이나 나무줄기 등에 붙어서 자라며, 한국(제주, 울릉도)과 일본에 분포한다. 바위수국 추출물과 분획물에서 총 페놀 함량. 총 플라보이드 함량, DPPH 및 ABTS 라디칼소거 활성의 항산화 실험 결과, 부탄올과 에틸아세테이트 분획층에서 강력한 항산화 활성이 관찰되었다. 또한 UVA를 조사한 인간 진피 섬유아세포 (human dermal fibroblast, HDF)데 대한 콜라겐 분해효소인 matrix metalloproteinase-1(MMP-1) 생성 억제 활성을 확인한 결과, 부탄올 분획층이 세포 생장 저해 없이 가장 우수한 효능이 확인되었다. 따라서 부탄올 분획층에서 주요 성분 분리 실험을 수행하여 총 4개의 화합물을 분리하였다; Chlorogenic acid (1), Quercetin-3-O-glucosyl-(1-2)-rhamnoside (2), Quercetin-3-O-xylosyl-(1-2)-rhamnoside (3), Quercitrin (4). 분리한 4개의 물질의 MMP-1 생성 억제 활성을 비교한 결과 화합물 2가 세포독성 없이 MMP-1 생성 억제 효능이 우수하였고, 이후 화합물 2의 광노화 예방 효능과 그 메커니즘을 확인하였다. 화합물 2는 MMP-1의 생성을 억제할 뿐만 아니라 procollagen type I의 생성을 증가시켰으며, MMP-1 생성에 관여하는 mitogen-activated protein kinase (MAPK)/activator protein-1 (AP-1) 신호전달경로를 하향 조절하며, 콜라겐 생성과 관련된 Transforming growth factor-β (TGF-β)/Smad 신호전달경로를 상향 조절하여 UVA에 의한 광노화 예방에 효능을 나타내었다. 이러한 결과들을 바탕으로, 바위수국은 항노화(anti-aging) 기능성 화장품 및 이너뷰티 기능성 식품 소재로 개발이 가능할 것으로 기대된다.
