This study aims to investigate the current status of young adult services centering on public libraries in Busan, Ulsan and Gyeongnam, identify problems, and then suggest tasks for service revitalization. The status of young adult services and librarians' perceptions in the 93 public libraries in Busan, Ulsan, and Gyeongnam that were registered in the 2021 National Library Statistics System and the Busan Metropolitan City Library Portal was investigated. As a result of the survey, 24% of public libraries have a space for young adult, and if there is dedicated space, it was found that the most number of bookshelves for young adult were installed inside the space. Libraries that provide young adult services accounted for 76% of the total, and the age range of the service targets was set between 13 and 18 years of age. The analysis revealed that it was difficult to provide services due to a combination of problems such as poor use and passive participation by young adult, lack of dedicated space, lack of manpower for program operation, and lack of budget. Nevertheless, most librarians agreed on the need to provide young adult-only spaces and young adult services. The tasks to revitalize young adult services in public libraries was suggested; expand young adult participation in the space creation and service planning/operation stage, create a space dedicated to young adult, diversify the contents of youth volunteer activities, secure the professionalism of the librarian in charge, human resource utilization, and expand public relations for services.

In knowledge based society, lifelong learning is increasing in order to meet educational needs of adult learners. Credit Bank system which is credited by individual experience, learning and qualifications are also emphasized for continuing learning participation. However, in spite of the importance of concern in the Credit Bank System, adult learners expectation and value are not high. The purpose of this study is to analyze participation valence and learning flow of adult learner in the Credit Bank System. The result of this study is summarized as follows: first, adult learners participated in the Credit Bank System to get new knowledge and skill based on internal and external motivation and requirement not involved with individual degree. Second, adult learners participating in the Credit Bank System are experiencing learning flow realizing that behavior of participation is compensated, adult learners are concentrating and feeling with satisfaction and pleasure to study. Third, participation in the Credit Bank System based on adult learner's own right learning requirement have been analyzed as it has a positive effect to the learning flow and have indicated that adult learners having high level of valence experience, recognition immersion, behavioral devotion, and egoistic immersion.

This study was conducted to find out how young black-tailed gulls (Larus crassirostris) recognize adult voice signals after hatching. For the experiment, adult voice recorded in the natural environment was played back at controlled intervals and intensity (dB) to 15 young gulls that were artificially hatched in the laboratory. The chirirah call frequency of young gulls increased as the intensity of the mew call increased. The chirirah response of the control group was highest to the mew call at intervals of 1.8s. The adult long ca11 and alarm call also showed similar results to the mew call when the interval and intensity were manipulated similar to the mew call. Based on the results of this experiment, it is assumed that the young black-tailed gulls recognize adult voice signals based on the simple structure of adult voice signals, that is, the interval and intensity of the voice.

Objectives: The purpose of this study was to examine the effects of parent-young adult relationship and self-differentiation on interpersonal problems among 20s. Method: The subjects were 504(195 male, 309 female) young adults in their twenties. The questionnaire was consisted of measures on the Parent-Child Relationship Instrument, Self-Differentiation Inventory, and Short form of Korean Inventory of Interpersonal Problems Circumplex. Descriptive, t-test, correlation, and hierarchical regression analyses were conducted with SPSS 23.0. Results: The major findings are as follow. First, the result showed that there were gender differences in the level of self-differentiation and interpersonal problems, while there were no differences between male and female in parent-young adult relationship. Second, correlational analyses results indicated that parent-young adult relationship was positively related with the level of self-differentiation. However parent-young adult relationship and the level of self-differentiation were negatively related with the interpersonal problems. Third, hierarchical regression analyses showed that parent-young adult relationship and the level of self-differentiation had significant influences on the interpersonal problems(moving toward people, moving against people and moving away from people among 20s). Conclusions: The results indicate that both parent-young adult relationship and the level of self-differentiation need to be considered to reduce young adults' interpersonal problems in counseling situations.

An increase in serum cholesterol is directly associated with high incidences of cardiovascular diseases (CVD) and atherosclerosis. Serum lipid profiles are highly dependent on dietary fatty acids and age. The purpose of this study was to examine the age-related effects of polyunsaturated/saturated fatty acid ratios and antioxidant supplementation under the control of the dietary peroxidizability index (PI) value on serum lipid profiles in rats. While the PI level of dietary fatty acids was controlled at 81.22, the P/S ratios of fatty acids were 0.38 and 4.81 (LP and HP). The diets were supplemented with a vitamin E 1000 mg/kg diet and a selenium 2.5 mg/kg diet (LPS and HPS). Female Sprague-Dawley rats ages 3 weeks (young) and 16 weeks (adult) were fed four different experimental diets for 4 weeks. The serum triglyceride concentration of LPS was significantly higher in young rats than in adult rats. The total-cholesterol concentration of LP and HPS were higher in young rats than in adult rats. The high-density lipoprotein-cholesterol (HDL-C) concentration of LP, LPS and HP was higher in adult rats than in young rats. The low-density lipoprotein-cholesterol (LDL-C) concentration was higher in young rats than in adult rats. T-C/HDL-C and LDL-C/HDL-C ratios were much higher in young rats than in adult rats. In conclusion, P/S ratios and antioxidant supplementation did not affect T-C/HDL-C and LDL-C/HDL-C ratios as risk factors of CVD in adult rats when we controlled the PI value in the diet Probably, the invisible and confounding effects of dietary PI value implicate the beneficial roles of dietary P/S ratios and antioxidants in CVD. Accordingly, controlling the dietary PI value may be advantageous to lower the risk of CVD in adult rats.

Purpose: This study aimed to explore young adult donors' experiences of living donor liver transplantation. Methods: A phenomenological research method was used. The participants were two women and six men. Data were collected through individual in-depth interviews from November 25th, 2019 to June 10th, 2020 and analyzed using Colaizzi's phenomenological method. Results: Five theme clusters extracted from the young adult donors' experiences were painful decision of a liver donation, the agony of both mind and body that overpowers youth, the bitter and bare face of reality that a young donor encounters, feeling the power of love that fills up the space of the organ removed, and liver donation becoming priming water for maturity. Conclusion: The results of this study provide a deeper understanding of the lives of young adult donors who have experienced unexpected difficulties as well as self growth from the donation. It is expected that the results can be of use for developing and applying customized nursing interventions for management before and after liver donation among young adult donors.
