Recently, concern about family safety is rising again as an important issue with the context of family healthiness and well-being in Korean society despite of the dramatic economic growth. The purpose of this study is to examine the status of family safety of singles and single-parent households and to investigate the effect of social capital on the level of their family safety. Data are from the 10th wave of Korea Welfare Panel Study analysing one-person households(N=2,017) and single-parent households(N=172). One-person households were categorized as three groups by age(the youths/middle-aged/the elderly) and single-parent households were also three by family types(mother-child/fahter-child/grandparent-child). The major results were as follows: First, the mean of family safety index was highest among middle-aged, while single youths had the fewest problems in terms of family safety. Second, social capital was found to vary by family structure. In the one-person households, all the levels of the social capital variables, including trust, bond, acceptance, and participation, differed significantly; only two variables, bond and embracement, differed in the single-parent households. Third, social capital differed between the low-income households and others significantly. Forth, the positive effects of social capital on overcoming family safety problems were investigated. In conclusion, social capital represents an alternative resource for overcoming economic hardship for low-income one-person/single-parent households, especially for middle-aged singles and father-child single-parent households. Based on these empirical results, theoretical implications were discussed with regard to family policy and programs.

본 연구는 기혼 중년 남성의 직업 스트레스, 직업 안정성, 우울, 가족유대감, 주관적 건강상태, 사회적 지지가 삶의 질에 미치는 영향요인을 알아보고자 하는 서술적 조사연구이다. 대상자는 B광역시, D광역시, J시에 거주하는 40~59세 중년 남성 149명의 설문지를 통해 자료를 수집하였고 SPSS/WIN 18.0프로그램을 이용하여 분석하였다. 연구결과, 삶의 질과 직업 스트레스(r=-.544, p<.001)과는 보통의 역 상관관계, 우울(r=-.748, p<.001)과는 높은 역 상관관계, 직업 안정성(r=.566, p<.001), 주관적 건강상태(r=.537, p<.001)과는 보통의 순 상관관계, 가족유대감(r=.712, p<.001), 사회적 지지(r=.739, p<.001)과는 높은 순 상관관계를 나타냈다. 삶의 질에 영향을 미치는 요인은 우울, 사회적 지지, 가족유대감, 주관적 건강상태, 현 직종의 근무년수, 규칙적인 운동여부 순으로, 전체 설명력은 75.1%로 나타났다. 따라서, 질적인 중년기 삶을 영위하기 위해 우울은 낮추고 사회적 지지 체계의 확충 및 가족유대감과 주관적 건강상태 증진, 현 직종에서의 근무년수를 높이기 위한 방안이 필요하다.

본 연구는 인터넷 사용, 가족 관계, 사이버폭력 피해 간의 관계를 모형 비교를 통해 검증한 것이다. 변인 간의 관계를 검증하기 위해 한국정보화진흥원의 2013년 인터넷중독 실태조사를 활용하였다. 구조방정식 분석을 통해 인터넷 사용이 가족관계를 완전 매개하여 사이버폭력 피해에 영향을 미치는 모형(모델 1)과 인터넷 사용이 가족관계를 부분 매개하여 사이버폭력에 영향을 미치는 모형(모델 2)을 비교하였다. 최종모형(모델 1)에 의하면, 인터넷 사용이 증가할수록 가족 간의 유대는 더 낮아지는 것으로 나타났고, 가족 간의 유대가 낮을수록 사이버폭력 피해는 더 커지는 것으로 나타났다. 본 연구는 인터넷 사용이 사이버폭력 피해에 직접적인 영향을 미치기 보다는 가족 관계가 두 변인간의 관계가 성립되는데 중요한 역할을 한다는 것을 밝혀낸 것에 의미가 있다. 본 연구결과를 참조하여 정책적 시사점을 제안했다.

Dihydrolipoamide dehydrogenase (E3) belongs to the protein family of pyridine nucleotide-disulfide oxidoreductases, including glutathione reductase (GR). The two subunits of human GR are covalently linked by an intersubunit disulfide bond between the pair of the Cys-90 residues. The corresponding residue (Ser-79) in human E3 was substituted to Cys using site-directed mutagenesis. The mutant was expressed in Escherichia coli and highly purified using an affinity column. About 40% of the mutants formed a spontaneous intersubunit disulfide bond linkage. This result implies that Ser-79 and possibly surrounding residues constitute one of the several intersubunit contact regions in human E3. It provides another good piece of evidence for the predicted high degree of the structural homology between human E3 and GR. Spectroscopic studies indicate conformational changes in the mutant.

This study was conducted to make a policy proposal for Korean grandparent-grandchildren families, analyzing what adversities adolescent grandchildren suffer when living in a grandparent-grandchild family, the types of Korean families and how family resilience appears as family power. In order to conduct this study, 20 consenting adolescents were selected for an interview from grandparent-grandchildren families recommended by the U City Healthy Family Support Center. This study suggests the following conclusions. First, we discussed divorce, death, financial bankruptcy related stress, economic difficulties in the present family, accidents involving family members of a grandparent-grandchild family, grandparents' serious disease, death, family conflicts and family comparisons with friends. Second, in the domain of family resilience, desire to maintain the family appeared as a Korean value. In addition, efforts to bond as an emotional family and grandchildren's attitudes of gratitude to grandparents are also expressed. However, family conversation appears weak due to the generation gap between adolescents and grandparents or complications from family stress. Third, the resilience in the family organization appeared weak since there are relatively insufficient socio-economic resources to support the family. This study makes several suggestions for family policies and shows the necessity to develop policies that reflect the needs of grandchildren and grandparents.

The purpose of this study was to investigate the strengths of single-parent families and the related variables based on the family strength approach. The major findings were as follows. First, good communication, family bond, children's adjustment and coping ability were characteristics of single-parent family strengths. Secondly, strengths of single-parent family were related to income and period of becoming a single-parent family. Thirdly, single parents who had a higher level of personal resources such as high self-esteem and economic stability perceived a higher level of family strengths. Fourth, single parents who had a higher level of social support perceived a higher level of family strength. Fifth, there was no interaction effect between personal resource and social resource on single-parent family strengths. Last, both personal and social resources had effects on the strength of single- parent family. Especially personal resource and self-esteem were the most important variables and had a strong influence on single-parent family strengths. The results of this study have important implications for theory, research and practice. Research on the strengths of the Korean single-parent family is new and more extensive investigation is required.

본 연구에서는 '알코올 의존 노숙인을 위한 사회복지적 지원의 핵심은 가족을 대체할 만한 영향력 있는 관계'일 수 있다는 문제의식을 바탕으로, 중림동 쪽방촌 일대에서 알코올 의존 노숙인을 지원하는 'H-공동체'의 사례를 스프레들리가 제시한 문화기술지 방식으로 탐색하였다. 연구결과 알코올 의존자들은 H-공동체를 중심으로 '가족을 대체할만한 관계'를 맺고 있었으며, 그 속에서 '정서적 유대감'을 형성하고 있었다. 그리고, 이는 '큰 정은 없어도 잔정으로 살아가기'라는 문화적 주제로 나타났다. 하지만, 그 관계와 유대감 정도는 다르게 나타났으며, 이는 각자의 생애과정과 건강, 나이, 경제 상황과 무관하지 않았다. 논의에서는 이 같은 차이를 '가족을 대체할만한 관계', '정서적 유대감', '참여' 정도를 통해 유형화시키고 논점으로 제안하였다. 결론에서는 연구결과를 바탕으로 알코올 의존 노숙인에게 필요한 함의를 제시하고 제언을 하였다.

Composite materials are effective in forming externally bonded reinforcements which find applications related to existing structures repair, attributed to their high strength-to-weight ratio and ease of installation. Among various composites, fibre reinforced polymers (FRP) have somewhat been largely accepted as a commonly utilized composite for such purposes. It is only recently that steel fibres have been considered as additional members of the FRP fibre family, intuitively termed as steel reinforced polymer (SRP). Owing to its low cost and permissibility of fibre bending at sharp corners, SRP is rapidly becoming a viable contender to other FRP systems. This paper investigates the bond behaviour of SRP-concrete joints with different bonded lengths (50, 75, 100, 150 and 300 mm) and widths (15, 30, 40, 50, and 75 mm) using single-lap shear tests. The experimental specimens contain SRP strips with a fixed density of steel fibres (0.472 cords/mm) bonded to the face of concrete prisms. The load responses were obtained and compared in terms of corresponding load and slip boundaries of the constant region and the peak loads. The failure modes of SRP composites are discussed, and the range of effective bonded length is evaluated herein. In the end, a new analytical model was proposed to estimate the SRP-concrete bond strength using a genetic algorithm, which outperforms 22 existing FRP-concrete bond strength models.

Formaldehyde and total volatile organic compounds (TVOC) from building materials have been known as main causes of IAQ problem in Newly-Constructed Multi-Family Houses. Because Multi-Family Houses are built in large quantities in a similar manner, inappropriate selection of building materials and method will detrimental affect IAQ. This research aims to identify major causes of Indoor Air Pollutants in Multi-Family Houses, by constructing Mock-Up & One-Room House. As a result, self leveling concrete, door, and furniture construction is a major cause of indoor formaldehyde increase, and tile bond is TVOC, and urethane water proof is Etylbenzene, and Xylene.
