Genetic change from broodstock to hatchery stock of the olive flounder Paralichthys olivaceus and effective number of breeders (Ne) were investigated by the different fertilized-egg collecting methods; E1 (eggs collected one day after spawning) and E2 (eggs collected two days after spawning) using seven microsatellite loci (Kop2, Kop22, Kop18, Kop3, Kop21, Kop9 and Kop26) for the better understanding of stock enhancement. Observed heterozygosity in three stocks ranged from 0.651 at Kop3 to 0.928 at Kop22, with offspring being slightly higher heterozygous over their parents. However, the genetic reduction of offspring was significant. The offspring allele number per locus was reduced to 23.5% for E1 and 17.6% for E2 of their maternal number. Ne to the hatchery stock was estimated to be 21.9 for E1 and 34.3 for E2. The inbreeding coefficients of populations El and E2 were 0.023 and 0.015, respectively. The present study suggests the extension of the egg collection period for a recovery of the genetic diversity in artificially produced offspring.

I have investigated questionaire concerning to the view of worth and construction of consciousness as to boarding system collegian who will employed in fisheries and maritime industries. The results were as follows; It appeared 38.9% that most collegian had a firm subjectivity about enrolled motive, selection of department, they had selected department according to the neighborhood recommendation, own squired score rather than the adaption and prospection, also it was appeared 55% that they had not satisfied with attending to their college, accordingly, the effectiveness of education were demolished in such aspects. It was appeared 74.3% that the education of fisheries and maritime college were divided into theory and practice pertinently also, 77.1% that modulate both technical education and human like education but as a general rule, the education of ocean going liscensed officer was appeared 7.1% only so that, the reformation of the curriculum and contents of education would be needed. As to the relation between professors and collegian, it was appeared 38.4% that well understanding professor, 18.1% that well teaching professor, 13.3% that they having humanlish relation with professor, 30.6% that they will benefit to vocational selection. consequently, the professor have to brings up the harmony on dint of education and industries. The things which collegian think to be worth were 43.6%, intercourse of friend 30.3%, circle activity. 6.6% listening lecture, also, the leisure activity after school were 74.7% with friends. 16.4% alone. consequently, the professor has to guide of leisure activity after lesson. most collegian has a good relationship with their parent(91.6%) but the respond with bad relationship was 8.4%. The most serious agony which collegian think about is vocational problems (48.9%), the other sex problem(22.5%). The objects consult with agony was aquaintance(54.9%). The parent(5.1%), professors(2.3%), the collegian who did not consult with agony was 20.9%. The parents and the professor is not object consult with their agony. so that, the professors has to strengthen the education according to the human nature. As to job after graduation of such college, collegian who wish to be taken job on the fisheries and maritime industry were 50.5%, on the contrary, the collegian who wish to be taken a job no relation with his major subjects was 29.1% especially, the collegian who want to be embarked was 26.3% (fisheries 23.3%, maritime 30.5%). so that, we must adopt the counter plan for the globalization and effective investment on the fisheries and maritime college.

To examine taxonomic relationships among 24 leaf mustard allies (Brassica juncea) derived from domestic collections and introduced species, principal component analysis (PCA) and cluster analysis on 16 morphological characters were carried out. Of 16 characters, total fresh weight, total dry weight, shoot fresh weight and leaf length were useful characters for the understanding of taxonomic relationships among them. Cluster analysis using scores of the principal components indicated that 24 leaf mustards could be grouped into domestic collections and introduced species at 1.0 of average distance in UPGMA. Moreover, in experiment of $F_{1}$ recombination test, heterosis appeared greatly in Sanchiohbachirimen takana A ${\times}$ Akaohba takana, Goheung namyang ${\times}$ Sanchiohbachirimen takana B, and Goheung namyang ${\times}$ Akaohba takana cross combinations. Sanchiohbachirimen takana A and Akaohba takana have a high parent combining ability for breeding cultivars using cytoplasmic male sterility.

The purpose of this study is to explore further understanding of variables, besides father's alcoholism, which relates to psychosocial adjustment among ADAF(adult daughters of alcoholic fathers). This study examines the relationship between father's alcoholism, family functioning, parental attachment and the psychosocial adjustment among the ADAF. From a larger sample of 463 female college students, 160 ADAF and a matched group of non-ADAF were identified to participate in the study. This survey was conducted in Seoul and Gyungi-do area. Participants completed self-report questionnaires, "The Korean Version of Children of Alcoholics Screening Test", "Inventory of Parent and Peer Attachment", "Satisfaction With Life Scale", "Self-esteem", "Beck Depression Inventory" and "Family Environment Scale". Path analyses was used to test the research question. Findings indicated that father's alcoholism had no direct effect on both the psychosocial adjustment of the ADAF and the family functioning. But father's alcoholism was significantly related to parental attachment. Family functioning was significant predictor of attachment to parents as well as psychosocial adjustment. Finally family functioning is important cause for parental attachment and psychosocial adjustment, specifically self-esteem and life satisfaction outcomes only. Therefore parental attachment was function as a mediator in the relationship between family functioning and psychosocial adjustment. In conclusion, this study showed that father's alcoholism did not predict outcome. We need to reconsider the assumption that direct link exists between adult adjustment difficulties and the presence of father's alcoholism. Implications for clinical and theoretical work with ADAF are discussed.

Objective : This study was conducted to verify the validity of the content of the Behavioral Pediatric Feeding Assessment Scale (BPFAS) following its translation into Korean, to allow the instrument to be used in Korea. Methods : The BPFAS was translated by the researcher and a pediatric occupational therapist with 12 years' experience. To validate the contents of the translated instrument, it was reviewed by three professors in the Department of Occupational Therapy who have taught how to evaluate instruments or conducted related research. The BPFAS was then translated back into English by a professional translator whose native language is English but who is fluent in Korean. The contents of the instrument were verified by using it to survey five parents with normally developed children aged between 9 and 72 months. The BPFAS instrument was successfully revised for use in Korea. Results : The content validity index (CVI) of the Korean version of the evaluation of children's eating behavior was an average of 0.9 points in the fluency area, an average of 0.8 points in the semantic area, and an average of 1 points in the technology area, and the overall average was 0.8 points or more. The average of the content understanding score was 3 points or more. Conclusion : It was confirmed that the Korean version of the BPFAS is an evaluation tool with high content validity and can be usefully used to gather data in clinical trials and research in Korea.

The objective of this study is to determine the structural relationships among the infant's temperament, father's involvement in child-rearing, and the infant's social and emotional behavior. To this end, research was conducted with 330 parents of infants aged 1 and 2 in 55 day care centers located in J city and I city, Jeollabukdo. Frequency analysis, reliability analysis, correlation analysis, confirmatory factor analysis, and structural model equation analysis were conducted using SPSS 21.0 and AMOS 21.0. First, the results of the structural model equation analysis showed that the infant's temperament had a negative correlation with leisure and guidance, while it had a positive correlation with activity and impulsivity, which are external manifestations of their social and emotional behavior. Father's involvement in child-rearing had a negative correlation with the adaptability and mood aspects of the child's temperament, and also with general anxiety, an internal aspect of his or her social and emotional behavior. Social and emotional behavior had a positive correlation with the approach avoidance aspect of the infant's temperament. Second, according to the results of the analysis of the route between the variables, infant temperament was found to be a significant route, having a statistically negative correlation with father's involvement in child-rearing. The results of this study showed that infant's temperament and father's involvement in child-rearing had effects on the infant's social and emotional behavior, and suggested the importance of having a proper understanding of the educational implications of the father's involvement in child-rearing, in terms of its effects on the infant's social and emotional behavior.

Purpose - The use of corporate social activities to implement the concept of corporate social responsibility enhances brand equity and attitude, and strengthens economic competitiveness. In areas such as mobile communications, companies take the responsibility of protecting customers and enhance the quality of the mobile communication service, helping to make an effort to obey the regulations of the public trade order and fair trade agreement, enabling a healthy society through communication with elderly living alone or youths without parents, and enhancing marketing strategies. Research design, data, and methodology - To test the hypothesis, a survey was conducted. The surveyed population includes people who use the big three mobile communication services. The survey was conducted from October 4th to October 14th, 2013. A total of 500 survey questionnaires were circulated and 483 were collected; out of these, 32 were excluded due to missing or incomprehensible information. The data was analyzed with SPSS 18.0 via frequency analysis, trust analysis, search factor analysis, relationship analysis, confirmation factor analysis using AMOS 18.0, and structural equation model analysis. Results - Research on corporate social responsibility has been frequently conducted recently. Companies are perceived as social constituents satisfying the social desires of people in addition to customer needs. Further, companies are returning profits to society to satisfy community needs, because there is greater emphasis on the social responsibilities of companies. Companies' social responsibilities should include marketing strategies and the identification of customer needs. This study shows that social service activities influence brand value, which influences customer attitudes; therefore, social service activities indirectly influence customer attitudes. In order to increase customers' purchasing intention, it is essential to improve brand image via social services and provide a distinctive quality of service. Conclusions - This research has used the purposive selection method in the empirical analysis to identify the effect of social services on brand value and customer attitude. Therefore, this study revealed that businesses, whose ultimate objective is to improve customers' purchasing intention, should promote their brand equity through corporate social responsibility activities and offer a distinct service quality. Limitations in the progress of research were found and future indications to overcome these limitations are suggested as follows. First, survey responders had a limited understanding of social responsibilities; therefore, this concept needs to be explained to people first. Second, the research was done on people who live in Daejeon; thus, it is not representative of the entire country. The research has to be repeated with people in other cities. Third, there is a limitation in the study because the purposive selection method was used on Daejeon customers. In the future, a more precise selection of the population is needed. Fourth, Daejeon has unique geographical and size characteristics. Thus, customers in Seoul and other areas may display different characteristics and research on them may reveal different findings. Therefore, again, this study has to be repeated in other areas.

This study investigates the relationship between the social supports & the transformational leadership from career mentors and high school students' GRIT & career preparation behavior. The purpose of this study was to provide baseline data for Development of Career-program so that they can provide effective career advice to students, through analyzing preceding researches that highlight the impact from career mentors on students' GRIT and career preparation behavior. For this study, the questionnaires for students' GRIT & career preparation behavior were completed by 257 sophomore high school students participating in the career mentor program. also, This data was analyzed to find student's perception of social supports and transformational leadership from career mentors. Correlation analysis was used to investigate the relationship among four variable(GRIT, career preparation behavior, career mentor's social supports, career mentor's transformational leadership) and regression analysis was used to find the influence from the career mentor's social supports and career mentor's transformational leadership on student's GRIT & career preparation behavior. The result showed the change of students' GRIT & career preparation behavior have risen on average. Also, it showed the change of students' career preparation behavior is influenced by career mentor's emotional support, informational support and individualized consideration. Lastly, the change of students' GRIT is influenced by career mentor's emotional support, appraisal support and individualized consideration. This result was able to identify the relationship and influence of career mentor who were limited to social support by their parents and teachers. And, it suggests that the appropriate social supports need to be provided to students by understanding the type of social supports that meet student's expectations.

Sexual dimorphism in birds refers to male-female differences in body size, plumage, color and/or behavior. In general, many seabirds, including the family of Laridae, are monomorphic in plumage-color, which makes the determination of sex difficult in the field because both parents also tend to share a great portion of parental care. The development of an inexpensive sexing tool facilitates understanding the degree of sex-specific parental care in the evolution of the life history. Here, we developed a non-invasive method for the determination of sex using the bill-head morphometric of known captive pairs and applied this tool to wild pairs to document factors underlying male-female parental care during the incubation period of Saunders's gulls (Saundersilarus saundersi). Males exhibited relatively larger bill-head ratios than their mates within naturally formed pairs in captivity, resulting in the determination of sex in12 wild pairs at the nest during the incubation period. Males and females equally shared the incubation role during the daytime, attending the nest at a high rate of 95%. However, the male's proportion of nest attentiveness greatly increased with time towards sunset, presumably reflecting the male duty for nighttime incubation. The present study provides a non-invasive method for the determination of sex in a monomorphic seagull species and highlights how male-female incubation behavior is associated with time of the day, rather than other ecological conditions.
