The objective of this research is to validate the BRQ(Brand Relationship Quality) Construct perceived by fashion product consumers. In order to establish and verify the BRQ scale, qualitative survey and quantitative survey were conducted together. 1592 copies of questionnaire were distributed to women in their 20s to 40s living in Seoul and other metropolitan areas from Dec. 26, 2005 to Jan. 8, 2006, and 723 copies of them were used for statistical data. Samplel(n=482)was used for empirical analysis, and sample2(n=241) was used for cross validity test. The data was analyzed using Exploratory Factor Analysis, Confirmatory Factor Analysis, and Pearson's Correlation Analysis. BRQ emerged from exploratory factor analysis as the hierarchical construct composed of six facets including 'self-connective attachment', 'symbol/mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge'. As the fit of this structural model was not good as a result of Confirmatory Factor Analysis, it was revised to have better fitting. Finally, empirical survey results indicate the hierarchical construct consisting of eight distinct BRQ facets including 'love/commitment', 'self-connection', 'symbol', 'mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge' as best representing the final 39item BRQ Scale. Reliability, construct validity, and cross validity of the construct were verified.

The PRQ instrument is parental perspectives of the parent-child relationship. It measured parent-child dimensions that include attachment and involvement. Also, it provides additional information on parenting style, parenting stress and satisfaction with the child's school. This study tested reliability and validity of the Korean version of Parenting Relationship Questionnaire-Child (K-PRQ-C). The K-PRQ-C was administered to parents of 713 elementary school children including 362 boys and 351 girls. They were from 1st to 6th grade children who were recruited form 4 elementary schools in Korea. Reliability was tested through internal consistency. We conducted confirmatory factor analysis. Moreover, scale inter-correlation was conducted for validity test. Discriminant validity conducted through administration to the parents of clinical children with emotional and behavior disorders. Construct validity was also examined through Korean version of the Parenting Sense of Competence. The results of confirmatory factor analysis indicated that the similar factor structures exist for PRQ-C and K-PRQ-C. The results showed a high level of internal consistency as well as construct and discriminant validity. These results showed valid psychometric properties for the K-PRQ-C. The K-PRQ-C provides a reliable and valid means of gathering information about the parent-child relationship. We discussed Implications for the use of the K-PRQ-C as a clinical tool and as a research instrument.

The Purpose of this study was to identify of parent-child relationship, Perceived social support and coping of female in late adolescents and its relationships. The underlying assumption is that Parent-child relationship based on internal working cognition affects on perceived social support and coping. The sample was consisted of 277 female students of college. The instruments used in this study were Parental bonding instrument (PBI)(Parker, Tupling & Brown. 1979), Personal resources questionnaire : PRQ-part II (Weinert ' Brant, 1987), and Way of coping (Folkman & Lazarus, 1985). The data was analyzed using frequencies, correlation coefficient, ANOVA. and t-test. As a result. perceived social support correlated positively with Parental care and negatively with parental overprotection. Perceived social support showed positive relationship with coping. Perceived social support differed according to parent-child relationship type. The group of 'affectionate constraint' high care and high overprotection. reported high perceived social support, but 'affectionless control'(low care and high overprotection) reported low perceived social support. The group of high perceived social support showed higher parental care and higher coping than low one. The group of high coping showed higher parental care, lower parental overprotection and higher perceived social support than low one. Findings from this study linking retrospective accounts of early parental relationships to current working models concerning the nature of supportive relationships are consistent with attachment theory that individual who, as children, experienced relationships with their parents that were independent-encourage. affectionate, and not overprotective developed working models of others as available to provide social support. This study confirmed that perceived social support significantly related to coping in dealing with stress.

To understand the attachment of micro algae and their subsequent growths on artificial surfaces immersed in seawater, the relationship between attachment of diatoms on the immersed artificial substrates and species pool in the surrounding water was investigated. We used acryl slides for the study of diatom attachment and examined the surrounding water samples collected in Incheon Harbour from July 1995 to February 1997. Variations of species composition and abundances by exposure time in seawater were investigated during the early phase of biofilm formation on various substrates, e.g. glass, acryl, titanium, copper and antifouling paint-treated slides. Immigration rates of diatoms to acryl slides during spring and winter were significantly correlated with the abundance of benthic diatoms in surrounding water ($r^2$=0.78, p<0.01, n=42), suggesting that immigration rates were affected by variations of benthic diatom abundances in surrounding water. Immigration coefficient of monoraphid diatoms was 5 times higher than that of biraphid diatoms, but relative abundance of monoraphid diatoms was 3 times lower than that of biraphid diatoms on acryl slides in spring. In winter, immigration coefficient and relative abundance of centric diatoms were higher compared to other raphe forms. These results suggest that the attachment of diatoms seems to be caused by the abundance and immigration coefficients of benthic diatoms in surrounding water. Pennate diatoms predominantly attached to all artificial surfaces throughout all experimental periods. Interestingly, centric diatoms predominantly attached to all artificial surfaces in winter. Hantzschia virgata, Licmophora abbreviata and Melosira nummuloides appeared dominantly on antifouling paint-treated slides, probably being tolerant of the antifouling paint. During incubations, the abundance of attached diatoms increased exponentially on glass, titanium and acryl slides with exposure time. The maximum abundance was highest on glass slide, followed by acryl, titanium, copper and antifouling paint-treated slides. The growth rates of attached diatom community on all artificial surfaces were higher at temperature of $24-25^{\circ}C$ than that of $2-3^{\circ}C$. The growth rate of attached diatoms on glass slide was generally higher compared to other slides during the study period. Dominant morphotypes of observed species with exposure time in seawater were prostrate form Amphora coffeaeformis, fan shape Synedra tabulata, stalk type Licmophora paradoxa and chain type M. nummuloides. A micro-succession in the attached microalgal community was observed. The composition of dominant species seems to be the result of species-specific response to gradually limited space with development of microalgal film.

Study was to identify the structural and functional characteristics of social support system to better provide social support to physically handicapped children. The research design was a comparative descriptive study and the data were obtained by use of interview and questionnaire. The result of this were as follows: 1. The physically handicapped children perceived that they had a fewer number of social support providers than the non-handicapped children. (t= -4.62, p<.001) 2. The physically handicapped children Perceived a lower level of social support than the non-handicapped children. (t= -3.93, p<.001) In the cases of 3 types of social support (social integration, attachment / intimacy, assistance/guidance), the handicapped children perceived a lower level of social support. 3. It was found that physically handicapped children and nonhandicapped children perceived degree of social support differently (x$^2$=72.08, p<.001). and also the two groups perceived in all types of social support differently. 4. The results of this study showed that parents, school mates, school teachers, brothers and sisters were significant providers of social support and between the two groups the supportive source ranked consistently. (rs=.83, p<.01) 5. The relationship between sociability and the support level was a positive correlation (r=.28, p<.01), the relationship between sociability and the size of the support network showed a positive correlation. (r=.47, p<.01) And with the increase in the number of friends. the number of support providers increased. (F= 4.46, p<.05).

The purpose of this study is to classify the characteristic and conduct a typological analysis of college students' attitudes toward remarriage by the elderly, employing Q-methodology. The results are as follows: College students strongly supported the opinion that remarriage relieves the elderly of loneliness, and that familial support is crucial for the remarriage to happen. They also rejected of the idea that the elderly would feel ashamed to remarry. Students' attitudes towards the elderly's remarriage fell into three classifications: the progressively accepting type, the realistically accepting type, and the conservatively accepting type. Type 1, "progressively accepting type" enthusiastically accepts and supports the elderly's remarriage as a progressive and emotive relationship. The "realistically accepting type" holds the opinion that remarriage in later life is based on overcoming loneliness or satisfying attachment need rather than love. This typology believes that the elderly would not be equal as spouses, and would not be overly distressed by public perception. The type 3, "conservatively accepting type" believes that remarriage would be likely to strain the elderly's relationship with other family members, that it will not be the beginning of a new independent life, but are generally accepting of the idea of remarriage in later life.

Plugging effect of open-ended pipe piles is known to have a close relationship with the ratio of an embedment depth to a pile diameter, i.e., the relative embedment ratio. To evaluate this relationship in the concrete, load tests are performed on the open and the close ended model piles varying the relative embedment ratio as well as the relative density of the model test ground. Cross-shaped hollow plates are attached at the open pile ends to reduce the effective pile diameters, on which load tests are also performed. As a result, it is confirmed that higher plugging effect may be obtained in the denser ground at lower relative embedment. However, 100% plugging effect can be obtained at the relative embedment ratio of 25 or bigger regardless of the density of the ground. Increment of the plugging effect by introducing the cross-shaped attachment can hardly be achieved.

According to aging society and social network society, the necessary of suitable alternative housing in the era has been increasing. The purpose of this research is to understand housing preference depended on the social relation of the elderly who lives in Beijing, China. The social relation was comprised of contact degree with child, contact degree with friend, contact degree with relative, degree of community participation, satisfaction with spouse and satisfaction with child. The housing preference was comprised of housing ownership, housing location, housing size and housing type. The survey was conducted on the elderly of 150 above fifties who lived in Beijing, China. For the result, the social relation was associated with the housing preference. Particularly, the relationship between the children was related to the housing ownership, housing location and housing size. The relationship between friends was related to the housing type. The level of community participation was related to the housing location. Social independence of the elderly, family cohesion, community attachment and adaption tendency were correlated with the housing preference. In conclusion, it was empirically identified that the social relation of the elderly had a relation with predicting housing preference. This result is expected to be useful in development of housing for the elderly in the future.

Purpose: The aim of this study was to evaluate the serum levels of oxidized low-density lipoprotein (oxLDL), anti-oxLDL, and myeloperoxidase (MPO) in hyperlipidemic patients with periodontal disease. Methods: This study included 123 patients with hyperlipidemia categorized based on metabolic control as mild to moderate (H1) (n=66) or poor (H2) (n=57), as well as systemically healthy controls (C) (n=68). Serum levels of lipids, oxLDL, anti-oxLDL, and MPO were evaluated, along with clinical periodontal parameters. Results: The percentage of bleeding on probing (BOP%) and the clinical attachment level were significantly higher in the H2 group than in the C group. Patients with hyperlipidemia had a relatively high risk of developing periodontal disease. The oxLDL and anti-oxLDL levels were higher in H2 patients with periodontitis than in the control or H1 patients with periodontitis. In the H1 and H2 groups, the ratio of total cholesterol to high-density lipoprotein was significantly correlated with gingival index, BOP%, and oxLDL levels. Conclusions: Our findings indicate that the lipoprotein-associated inflammatory mediators of oxLDL, anti-oxLDL, and MPO may play an important role in the relationship between periodontal disease and hyperlipidemia.

Objectives: The purpose of this study was to conduct a meta analysis of the previous studies on parental factors related to psychological and social maladjustment of school children and to examine the moderate effects of publication year using the meta-regression analysis. Method: Subjects of studies was academic journals and thesis published on 1996-Feb. 2016. Final result of selection was 353(122 journal articles, 231 master's thesis & dissertations) and total number of sampling was 126,776 school children. Results: Parental factors had medium effect sizes on psychological and social maladjustment of school children. Parental risk factors had bigger effect size than protective factors on children's maladjustment. There were a tendency that effect size of some parental factors were increased as publish year went by. Conclusions: Attachment, positive communication, and positive marital relationship were major protective factors which had reduced maladjustment of children. Psychological control and negative marital relationship were the strongest risk factors. The impact on parental factors on maladjustment of children were getting stronger recently.
