This study investigated the relationship between social support and caregiving self-efficacy among 530 mothers of persons with intellectual disabilities in their childhood(age 3-12), adolescence(age 13-18), and adulthood(age 19-35), exploring the moderating effect of the life span affiliation of the children with disabilities. The analysis revealed that greater perception of social support predicted higher level of caregiving self-efficacy for all the mothers. However, the moderating effect was detected indicating that there were differences in the effects of social support on caregiving self-efficacy across groups. Although social support was found to have some positive effects on caregiving self-efficacy for each group of mothers of both adolescents and adults, no effects for a group of mothers of children. These findings suggested that greater emphasis be placed on the expanded provision of social support for families of persons with intellectual disabilities in their developmental stages following the childhood.

Purpose - Recently, the management conditions of small independent retailers are getting worse everyday as large-scale marts and franchised convenience stores are increasing. The objective of this research is to find out the antecedents and consequences of cooperation in voluntary chain in order to enhance small independent retailer's competitiveness. Voluntary chains, also called affiliation or symbol groups, or allied group represent a high market shared in some European countries like Italy, France, and Germany. Nevertheless, there are still limitations in this research from academic fields. Drawing from network theory, the author investigates the relationship between antecedent factors in voluntary chain cooperation, such as participation benefits, justice of compensation, and autonomy in voluntary chain, and relationship specific asset. The author also attempts to examine the relationship between the relationship specific asset and cooperation of voluntary chain member shop and cooperation and consequence factors of voluntary chain cooperation, such as efficiency, group cohesiveness, and long-term relationship. Research design, data, and methodology - The author presented conceptual framework integrating the major antecedents and consequences of voluntary chain cooperation. The data were collected from 174 independent small retailers who joined K-voluntary chain. K-voluntary chain consists of small independent retailers. In accordance with their status, each entrepreneur associated with the voluntary group can own one or more outlets and can be a part of the life and the decision-making process of the group. This participation is not based on company turnover or on the number of outlets, but based on a one member, one vote system. To verify the research model and test hypotheses, the author carefully investigated the reliability, content validity, convergent validity, and discriminant validity of the proposed model. The data were analyzed by using SPSS 18.0 and AMOS structural equation modeling program. Results - The results of this study are as follows. First, as antecedent variables, participation benefits and justice of compensation have positive effect on the relationship specific assets of voluntary chain members. Second, voluntary chain members' relationship specific asset also directly related to the level of its cooperation to chain headquarter. Third, cooperation of voluntary chain member shop facilitates efficiency, group cohesiveness, and long-term relationship. Unexpectedly, there are no effect autonomy in voluntary chain to relationship specific asset. Conclusions - This research shows several theoretical and practical implications to both marketing scholars and marketers. In terms of theoretical implications, this study applies to network theory and network theory variables to explain the antecedent and consequence factors of cooperation in voluntary chain. From the point of view from business management, most of all, this study shows the way how to reinforce competitiveness of voluntary chain. Specifically, it is necessary for voluntary chain headquarter to give higher level of participation benefit and justice of compensation to its members. Second, the results also indicate what the consequence factors of cooperation in voluntary chain. In other words, to increase the level of marketing efficiency, group cohesiveness, long-term orientation in retail voluntary chain, and chain headquarter need to facilitate participants' cooperation.

This study conducted a survey and investigated students' opinions and design preferences to physical education (PE) uniforms for elementary, middle and high school students using PE uniforms for the following purposes: to increase satisfaction with PE uniforms; present basic data for the development of PE uniforms helping to improve the quality of school life; and propose the development direction of PE uniforms. PE uniforms shall be developed with the components of uniforms, symbolism, functionality and aesthetics. The symbolism of PE uniforms expresses the affiliations of people wearing them and makes them have a sense of affiliation. The functionality presents convenience in students' physical activities and intramural/extracurricular activities. The aesthetics reflects the aesthetically sophisticated sport wear trend in PE uniforms. The development direction of PE uniforms was organized based on the result of analyzing and investigating students' opinions and design preferences to PE uniforms. There were differences in students' opinions and preferences to PE uniforms according to the type of student groups (elementary, middle and high school). In addition, there were clear gender-differences in the same student group. An effort might be required to reflect students' preferences because PE uniforms which students had currently worn at school had been manufactured without the reflection of students' opinions.

The purpose of this study was to examine the effect of preceptorship on On the Job Training of new nurses. The research design was a retrospective survey and one group pre-post test design. The subjects were 49 entry nurses and 49 preceptors. The data were collected from Feburary 1, 1998 to December 1, 1998. One questionnair applied in this study consisted of general characteristics, the responses of new entry nurses and their preceptors and their qualities. The other questionnair consisted of job satisfaction of new entry nurses and preceptors and their competencies. The data were analyzed for frequencies, mean score, standard deviation, t-test, and ANOVA. The results of the study were as follows: 1) Preceptees's responses were that the nurses' affiliation of unit, cooperation of other nurses, and competencies of nursing skills improved after OJT applied preceptorship. 2) Preceptors's answers were that preceptorship had a positive effect on their continuing education. 3) While preceptees's job satisfaction scores were high in interaction, administration, and organization, they were low in autonomy and pay. 4) Pre-competency scores were the same as post-competency scores. 5) After preceptorship, preceptors responded that their nursing skill & communication competency increased, but their nursing administration competency decreased. 6) Finally, preceptorship's other effects were as follows: (1) Checklists for preceptee education at the nursing unit were developed separately. (2) It was proved that 'preceptor interview note' was effective on manage preceptorship. (3) We obtained duty overlap periods; medicalsurgical units-1 month, 5 ICU-2 months, operation room-3 months. (4) We prepared a preceptor program based on the study results.

Purpose - This paper investigates whether managerial overconfidence is associated with firm-specific crash risk. Overconfidence leads managers to overestimate the returns of their investment projects, and misperceive negative net present value projects as value creating. They even use voluntary disclosures to convey their optimistic beliefs about the firms' long-term prospects to the stock market. Thus, the overconfidence bias can lead to managerial bad news hoarding behavior. When bad news accumulates and crosses some tipping point, it will come out all at once, resulting in a stock price crash. Research design, data and methodology - 7,385 firm-years used for the main analysis are from the KIS Value database between 2006 and 2013. This database covers KOSPI-listed and KOSDAQ-listed firms in Korea. The proxy for overconfidence is based on excess investment in assets. A residual from the regression of total asset growth on sales growth run by industry-year is used as an independent variable. If a firm has at least one crash week during a year, it is referred to as a high crash risk firm. The dependant variable is a dummy variable that equals 1 if a firm is a high crash risk firm, and zero otherwise. After explaining the relationship between managerial overconfidence and crash risk, the total sample was divided into two sub-samples; chaebol firms and non-chaebol firms. The relation between how I overconfidence and crash risk varies with business group affiliation was investigated. Results - The results showed that managerial overconfidence is positively related to crash risk. Specifically, the coefficient of OVERC is significantly positive, supporting the prediction. The results are strong and robust in non-chaebol firms. Conclusions - The results show that firms with overconfident managers are likely to experience stock price crashes. This study is related to past literature that examines the impact of managerial overconfidence on the stock market. This study contributes to the literature by examining whether overconfidence can explain a firm's future crashes.

Background: Loading of excess nutrient via bioremediation of polluted sediment to overlying water could trigger anoxia and eutrophication in coastal area. The aim of this research was to understand the changes of overlying water features such as dissolved oxygen (DO); pH; oxidation reduction potential (ORP); $chlorophyll-{\alpha}$ ($Chl-{\alpha}$); and nitrogen nutrients ammonia ($N-NH_4{^+}$), nitrate ($N-NO_3{^-}$), and nitrite ($N-NO_2^-$) when the sediment was not treated (control) and treated by calcium peroxide for 5 weeks. Methods: The water samples were analyzed for measuring physical and chemical properties along with the sediment analyzed by polymerase chain reaction (PCR) including denaturing gradient gel electrophoresis (DGGE) for identifying the phylogenetic affiliation of microbial communities. Results: Results showed that due to the addition of calcium peroxide in sediment, the overlying water exposed the rise of dissolve oxygen, pH, and ORP than control. Among the nitrogen nutrients, ammonia inhibition was higher in calcium peroxide treatment than control but in case of nitrate inhibition, it was reversed than control. $Chlorophyll-{\alpha}$ was declined in treatment column water by 30% where it was 20% in control column water. Actibacter and Salegentibacter group were detectable in the calcium-peroxide-treated sediment; in contrary, no detectable community ware found in control sediment. Both phylogenetic groups are closely related to marine microflora. Conclusions: This study emphasizes the importance of calcium peroxide as an oxygen release material. Interaction with peroxide proved to be enhancing the formation of microbial community that are beneficial for biodegradation and spontaneity of nutrient attenuation into overlying water.

Regular dental visit of disabled patients is an important strategy for maintenance of oral health because of the lack of awareness of oral care. But there is limited information about follow up period in disabled patients after dental treatment. The aim of this study was to investigate the pattern of dental visit and dental management of special care needs patients according to the types of disabilities. A total of 140 patients who received dental treatment at Seoul National University Dental Hospital from 2010 to 2012 were reviewed. Patients were divided 3 groups according to the types of disabilities (disorder of external physical function, disorder of internal organ, psychic disability). Patient's characteristic, dental treatment performed, follow up period and frequency were investigated. The mean follow up period was 28.2 months and average frequency of visit was 3.69 times per year. There was no difference in period and annual visit between 3 groups, but significantly difference in cooperation with medical hospital in affiliation. Regular check-up was the most common dental treatment in all groups. In psychic disorder group, the proportion of sedative treatment was significantly higher than other groups. The results of this study provide information necessary for treatment planning and dental management of disabled patients.

Two novel strains of the Cytophaga-Flexibacter-Bacteroides(CFB) group, designated Gsoil $219^T$ and Gsoil $238^T$, were isolated from soil of a ginseng field of Pocheon Province in Korea. Both strains were Gram-negative, aerobic, nonmotile, nonspore-forming, and rod-shaped. Phylogenetic analysis based on 16S rRNA gene sequences indicated that both isolates belong to the genus Chitinophaga but were clearly separated from established species of this genus. The sequence similarities between strain Gsoil $219^T$ and type strains of the established species and between strain Gsoil $238^T$ and type strains of the established species ranged from 91.4 to 94.7% and 91.6 to 94.2%, respectively. Phenotypic and chemotaxonomic data(major menaquinone, MK-7; major fatty acids, $iso-C_{15:0}\;and\;C_{16:1}\omega5c$; major hydroxy fatty acid, $iso-C_{17:0}3-OH$; major polyamine, homospermidine) supported the affiliation of both strains Gsoil $219^T$ and Gsoil $238^T$ to the genus Chitinophaga. Furthermore, the results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of both strains from the other validated Chitinophaga species. Therefore, the two isolates represent two novel species, for which the name Chitinophaga soli sp. nov.(type strain, Gsoil $219^T=KCTC\;12650^T=DSM\;18093^T$) and Chitinophaga terrae sp. nov.(type strain, Gsoil $238^T=KCTC\;12651^T=DSM\;18078^T$) are proposed.

Microbial diversity analyses were performed in several geothermal areas in Indonesia using a culture-independent approach with 16S rRNA gene sequencing. All areas and the majority of samples were noted as being affiliated with Proteobacteria. In addition, unclassified bacteria with no phylum affiliation were detected at an incidence rate of 20.0-26.5% in every location. The majority groupings in the geothermal hot stream in Cisolok belonged to ${\beta}$-Proteobacteria (27.1%) and Cyanobacteria (11.0%), whereas the majority from the volcanic area in Kamojang was ${\gamma}$-Proteobacteria (51.5%) followed by Aquificales (12.9%). The predominant groups around an underwater thermal vent in the sea at Likupang were ${\gamma}$-Proteobacteria (33.3%) and then Bacteroidetes (27.6%). This detailed microbial community analyses of each area strongly support a possible association with plausible community groups and environmental habitats, such as extremely geothermal or marine habitats. This study has significantly contributed to the expansion of scientific knowledge of the microbial community in Indonesia.
