Positive affect has beneficial consequences in various life domains including social relational aspect. This study proposes that 'joy,' a highly arousing positive social emotion, promotes emotionally supportive reactions during a social interaction. In Study 1, after controlling for confounding personality characteristics (e.g., extraversion, agreeableness, adult attachment) and cognitive variables (e.g., empathy, self-esteem), positive affect predicted the amount of emotional support and enthusiasm one showed to a person who was describing a positive experience. The arousal dimension of positive emotion appeared to be the key in creating this outcome. Study 2 found that people were most likely to react in supportive ways (e.g., more laughing, emotion sharing, and active-constructive responses) to other's conversation after viewing a joy-inducing (rather than pride, awe, calm) film clip. These results partly explain why happy people are socially popular and suggest that one of the central functions of "joy" is to promote social bonding with others.

Men should be able to do whatever they want to and want to safely protected at home which is special domain for them. The disabled live mentally uncomfortable lives at home which should be a place where they should be comfortable and convenient. Renovation projects started in Incheon since 2009 by commencing renovation projects for the disabled by the government and welfare centers. Since the project is a program supported by the government or welfare centers thus priority on renovation was decided and carried out by in-depth interview to decide areas to renovate because of limited budgets. This paper is aimed to propose plans for renovating homes according to priority for renovation for dwellers when renovating homes for the disabled with limited budgets. Renovating home for the disabled can be broadly divided into physical, environmental, esthetic renovations, and physical renovation is a basic renovation for daily lives without restrictions in living and include easy movements, accesses to each rooms and adequacy of movement, easily accesses related with easily accessible distance and height, safety to prevent accidents caused by physical inabilities. Environmental renovation is general supports becoming the base of daily living and include control for controlling lighting, heating, air quality for comfortable environments in living space and pleasantness to maintain bright and pleasant interior with sufficient light. Esthetic renovation includes expression of identity by expressing image of one self and visual effects or spatial consideration for hobbies to enjoy comfortable and rich lives.

Symbol mark started with expressing the symbolic form through the long history of human beings, in order to transmit self or group's life and thoughts, and since the Industrial Revolution, symbol mark has beer used for the business activities of enterprise, along with the acquirement of term 'CI'. The symbol mark design of A.E.G, designed by Peter Behrens in 1907 is the onset of symbol mark in the CI concept, and the concept of CI and symbol mark was introduced to our nation in the early of 1970s. Since then, until now, CI has reflected the phase of the times as a key factor of CI, while repeating numerous changes, and recently, it is a state that the expression methods of symbol mark have been varied with the popularization of trend, appealing to emotion in the whole society and culture. Accordingly, this thesis examines the corporate symbol mark through the portfolio of representative CI specializes companies from the introduction period of CI to the present, and analyze the features of the time in order to present the basis of the direction of symbol mark design for the creation of future corporate images.

The purpose of this research was to analyze the clothing behavioral attributes of male music enthusiasts. A questionnaire was developed based on previous researches. Respondents were men who were concerned with music in terms of a job, a major or a hobby. A total of 200 responses were analyzed by SPSS 20.0 through factor analysis with Varimax rotation, ANOVA with post-hoc test(SNK-test) and ${\chi}^2$-test. Music preference was classified into 3 factors: New age/jazz, Hiphop/dance, and Metal rock/ballad factor. 5 Clothing purchasing orientation factors were extruded: hedonic, planned, convenience, brand pursued, and fashion pursued purchasing orientation. Using those factor scores, 3 groups were classified: Group1(G1), preferring Hiphop/dance music with lower hedonic and brand/fashion pursued purchasing orientation; G2, preferring Hiphop/dance music with no interest in clothing shopping and fashion; G3, preferring New age music with high convenience and brand pursued purchasing orientation. In addition, there were significant differences among groups in clothing behavior such as social ostentation, individuality, self-expression, fashionability, conformity; in purchase motivation such as hedonic and trend/designer oriented purchase motivation; in information source like advertisement/media source; and in store choice criteria such as store light/music and popularity. The findings showed even the enthusiasts for the same music showed the different sopping orientation and different clothing behavior, suggesting that a personal value or taste can be a plausible factor to figure out attributes of consumers. An interest/involvement in clothing could be helpful to subdivide the music enthusiasts as the target market.

The purpose of this study is to find the Korean women's view to pregnancy within the Korean cultural context, to help nurses understand psychosocioemotional schema of the pregnant women, and to contribute to theory-building on the meaning of pregnancy. The interviewees were 21 women in their twenties or thirties and they were selected by theoretical sampling technique. Thirteen women of the interviewees were single and others married. Data were collected by in-depth interviews from September November in 1994. Interviews were tape-recorded and transcribed. Data were analyzed by Van Kaam's phenomenological method. Results were as follows. Eighty two descriptive expression were found and they were grouped under fourteen common factors. These are 「to maintain family」, 「instinct」, 「obligation」, 「what one should do」, 「to make home」, 「to tie couple firmly」, 「means to overcome a period of lassitude」, 「token of love」, 「hope」, 「to avoid loneliness」, 「wanted to have a baby」, 「to provide for old ages」, 「to be a mother」, 「to achieve her desire through baby」. Finally, fourteen common factors were grouped under four higher categories. Five common factors, 「to maintain family」, 「instinct」, 「obligation」, 「what one should do」, 「to make home」 were grouped under〈custom〉. Three factors, 「to tie couple firmly」, 「means to overcome a period of lassitude」, 「token of love」 were grouped under 〈love between couple〉. Four factors, 「hope」, 「to avoid loneliness」, 「wanted to have a baby」, 「to provide for old ages」 were grouped under 〈pursuiting safety〉. Two factors, 「to be a mother」, 「to achieve her desire through baby」 were grouped under 〈self-fulfillment〉. At present, the most distinguishing motivation of childbearing was rooted in the cultural custom. Korean women thought that it was their duties to have children and children were necessary in life. But they were beginning to recognize that baby could tie couple more firmly and get rid of their loneliness. Korean women no longer considered their children as the one who would take care of them when they were old or who would satisfy their unmet needs. As pregnancy is not women's duty only, authors recommend further studies on men's view to pregnancy.

Background: Graft-versus-host disease (GVHD) is initiated when alloreactive donor T cells are primed by host APCs to undergo clonal expansion and maturation. Since there is a controversy regarding the role of nonhematopoietic cells in GVHD, we wanted to investigate the influence of MHC disparity on nonhematopoietic cells on the pathogenesis of GVHD in the MHC-haplomismatched C57BL/6 ($H-2^b$) or DBA/2 $(H-2^b){\rightarrow}$unirradiated ($C57BL/6{\times}DBA/2$) $F_1(BDF_1;\;H-2^{b/d})$ murine model of acute GVHD (aGVHD) or chronic GVHD (cGVHD). Methods: We generated ($BDF_1{\rightarrow}C57BL/6$), ($BDF_1{\rightarrow}DBA/2$), and ($BDF1{\rightarrow}BDF_1$) chimeras and examined GVHD-related parameters and donor cell engraftment in those chimeras. Results: Using this experimental system, we found that 1) severe aGVHD across MHC Ag barrier depends on the expression of nonhematopoietically rather than hematopoietically derived alloAgs for maximal GVHD manifestations; 2) host APCs were sufficient to break B cell tolerance to self molecules in cGVHD, whereas host APCs were insufficient to induce autoimmunity in aGVHD; 3) donor cell engraftment was greatly enhanced in the host with MHC-matched nonhematopoietic cells. Conclusion: Taken together, our results provide an insight into how MHC disparity on GVHD target organs contribute to the pathogenesis of GVHD.

As the demand for large-scale analysis of gene expression using DNA arrays increases, the importance of the surface characterization of DNA arrays has emerged. We compared the efficiency of molecular biological applications on solid-phases with different surface polarities to identify the most optimal conditions. We employed thiol-gold reactions for DNA immobilization on solid surfaces. The surface polarity was controlled by creating a self-assembled monolayer (SAM) of mercaptohexanol or hepthanethiol, which create hydrophilic or hydrophobic surface properties, respectively. A hydrophilic environment was found to be much more favorable to solid-phase molecular biological manipulations. A SAM of mercaptoethanol had the highest affinity to DNA molecules in our experimetns and it showed greater efficiency in terms of DNA hybridization and polymerization. The optimal DNA concentration for immobilization was found to be 0.5 ${\mu}M$. The optimal reaction time for both thiolated DNA and matrix molecules was 10 min and for the polymerase reaction time was 150 min. Under these optimized conditions, molecular biology techniques including DNA hybridization, ligation, polymerization, PCR and multiplex PCR were shown to be feasible in solid-state conditions. We demonstrated from our present analysis the importance of surface polarity in solid-phase molecular biological applications. A hydrophilic SAM generated a far more favorable environment than hydrophobic SAM for solid-state molecular techniques. Our findings suggest that the conditions and methods identified here could be used for DNA-DNA hybridization applications such as DNA chips and for the further development of solid-phase genetic engineering applications that involve DNA-enzyme interactions.

Lysophosphatidic acid (LPA) is a lipid messenger mediated by G protein-coupled receptors (LPAR1-6). It is involved in the pathogenesis of certain chronic inflammatory and autoimmune diseases. In addition, it controls the self-renewal and differentiation of stem cells. Recent research has demonstrated the close relationship between periodontitis and various diseases in the human body. However, the precise role of LPA in the development of periodontitis has not been studied. We identified that LPAR1 was highly expressed in human periodontal ligament stem cells (PDLSCs). In periodontitis-mimicking conditions with Porphyromonas gingivalis-derived lipopolysaccharide (Pg-LPS) treatment, PDLSCs exhibited a considerable reduction in the cellular viability and osteogenic differentiation potential, in addition to an increase in the inflammatory responses including tumor necrosis factor-α and interleukin-1β expression and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation. Of the various LPAR antagonists, pre-treatment with AM095, an LPAR1 inhibitor, showed a positive effect on the restoration of cellular viability and osteogenic differentiation, accompanied by a decrease in NF-κB signaling, and action against Pg-LPS. These findings suggest that the modulation of LPAR1 activity will assist in checking the progression of periodontitis and in its treatment.

A family resilience approach aims to identify and fortify key interactional processes that enable families to withstand and rebound from disruptive life challenges. Walsh(1998) described family belief systems, organizational patterns, and communication processes as the three main keys of family resilience. The purpose of this study was to identify the three key factors of family resilience in case of divorced female single-parent families in Korea. The study participants were seven divorced mothers who were living in the institutional facility for female single-parent families. Using a qualitative approach, in-depth interviews were audiotaped and transcribed verbatim for analysis. The study findings were as follows. First, the participants showed positive thinking rather than fear about the adversity induced by the divorce. They also showed the senses of competence, control, and self-esteem. However, the senses of transcendence and spirituality were barely evident. Second, emotional and economic supports from parents, brothers and sisters, and community networks (i.e., mother-child protection institution, healthy family support center) enhanced the family resilience of the participants. Third, the participants showed clear communication, open emotional expression, and shared decision making. This study suggests that more counseling services and parent education be provided by healthy family support center and institutional facilities as important family resilience factors for divorced female single-parent families who are below the poverty line.
