The purpose of this study was to measure the causal relationships among fish consumption behavior, attitude towards fish eating, health involvement, perceived convenience, and age. A total of 235 questionnaires were completed. A structural equation model was used to measure the causal effects of the constructs. The results of the study demonstrated that the structural analysis results were an excellent model fit for the data. The influence of age on attitude towards fish eating, health involvement, and perceived convenience was statistically significant. As expected, attitude towards fish eating, health involvement, and perceived convenience had significant effects on fish consumption behavior. Moreover, age had a significant indirect effect on fish consumption behavior through health involvement. Age also had a significant indirect effect on fish consumption behavior through perceived convenience. By developing and testing conceptual models that integrate the relationships among age, psychological variables, and fish consumption behavior, this study may offer a deeper understanding of the complex relationships among the variables. A greater understanding of these complex relationships can improve the managerial diagnoses of problems and the opportunities for different marketing strategies, including product development and marketing communications.

The effect of broodstock age on the spawning performance of cultured abalone, Haliotis discus hannai, was assessed for five age groups (3, 4, 5, 6, 7 years old). Spawning performance of the five age groups was assessed in terms of the percentage of spawning abalone, eggs per spawning female, fertilization rates, hatch rates and attachment rates per spawning. The percentage of spawning abalone increased along with broodstock age, reached maximum in female groups of 5- and 6-year age (60%), and in male group of 6-year age (100%), subsequently decreased in 7-year age group. The number of eggs produced per spawning also increased with broodstock age, and the maximum was found in 6-year age. Although the number of spawned eggs for the oldest abalone declined, it still spawned much more eggs than 3, 4, and 5 years old females. The fertilization and hatch rates were obviously larger for 4-6 years old group than the younger and older abalones. The maxima were found in 5-year age group (96.0% and 84.5%), and the minimum were appeared in 7-year age group (79.3% and 58.2%). The attachment rate increased with broodstock age, reached maximum in 6-year age group (33.6%), although the increment gradually declined. The attachment rate for 7-year age group rapidly decreased (16.6%). These results suggested that broodstock age affected the spawning performance of H. discus hannai, which peaked between 5 and 6 years old, and broodstock should be bred during this period for hatchery production.

Objectives: This study investigated the gender and age differential effect of major chronic diseases on activity of daily living (ADL) disability. Methods: Surveyfreq and Surveylogistic regression analyses were employed on the 2005 Korean National Health and Nutrition Examination Survey (KNHANES) with a sample of 3,609 persons aged 65 - 89. Results: After adjusting for potential covariates, stroke, among elderly men more so than women, had a 2-3 times greater odds of engendering ADL disability in the 65-69 (p < 0.05) and 70-79 age groups (p < 0.01). In comparison to elderly women, cancer, diabetes, and incontinence in elderly men was associated with a higher risk of ADL disability in the 70 - 79 age group (p < 0.05), and this association was also observed for pulmonary disease in the 80-89 age group. Among elderly women, however, a significant association between incontinence and ADL disability was identified in all three age groups. In addition, this association was found in pulmonary disease and diabetes in elderly women aged 70 - 79 years. Significant gender differences were observed in the association between stroke in the 60 - 79 age group and cancer in the 70 - 79 age group. Conclusions: Age and gender differences were observed in the effect of chronic diseases on ADL disability.

The Influence of age on the endothelial modulation of angiotensin II (AII)-induced contractile response was investigated in isolated aortic rings of rats ranging in age from 0.7 to 20 months. Hemoglobin and L-NAME were used to examine whether age-related changes in the EDRF-releasing system were involved in endothelial modulation of All-induced contraction in rat aorta. In all five age groups (0.7, 1.5, 3, 6, 20 months), hemoglobin (10 ${\mu}$M) significantly enhanced All-induced contractile response only in aorta with endothelium intact. L-NAME (10 ${\mu}$M) Produced a significant enhancement in All responses in endothelium-intact aortas from rats aged 0.7 and 1.5 months, but it had no effect in aortas from older rats aged 6 and 20 months. Indomethacin (10 ${\mu}$M) did not affect All-induced contractile responses in both endothelium intact and removed aortas from rats at the age of 0.7 to 20 months. Hemoglobin (10 ${\mu}$M) abolished acetylcholine-induced relaxation response in aortas from young and old rats. L-NAME completely abolished the relaxation in aortas from young (0.7 and 1.5 months), but incompletely in aortas from older (6 and 20 months) rats. The sensitivity of endothelium-dependent relaxation to A23187 increased with age between ages of 0.7 and 6 months, with no further increase noted up to 20 months of age. These results suggest that endothelial modulation of AII-induced contraction in rat aorta might involve age-related alteration in EDRF-releasing system, probably via post-receptor mechanism.

The purpose of this study was to investigate the effect of physical type and age on preference for line in women's clothing design. Line preference in clothing design was concerned with varying in length, direction, division, and shape. All of the preference measures were devised specifically for this study. Furthermore, items on height and weight for physical type as well as age of the subjects were included in the questionnaire. Data were obtained by means of structured interviews and self-administered questionnaires from 588 women ($20\~60$ years of age) in Seoul. Analysis was by One·way ANOVA, Chi-square ($X^{2}$), and Scheffe test. It was found that 4 categories of line preference were affected by both body type and height. An age effect was found on 3 categories of design lines; however, preference for 2 categories of design lines in clothing styles were unaffected by either physical type or age. It was concluded that body type, height, and age are powerful predictive variables for line preference in clothing design. Generally, there was some similarities in preference for lines among slim body types, tall figures, and younger age group as well as heavy body types, short figures, and older age group.

Objective: This study aimed to examine the sequential mediating effects of children's perceived maternal acceptance and peer acceptance in the relationship between maternal warmth and first grade children's school adjustment. Methods: Participants in this study were 979 seven-year-old children(498 boys, 481 girls) recruited for the Korea Child Panel Study. Data were analyzed by analyzing descriptive statistics, correlations, and significance of serial mediation pathways using SPSS 18.0 and PROCESS Macro 3.4. Results: Maternal warmth at age five effected perception of maternal acceptance at age six. Perceived maternal acceptance at age six effected perceived peer acceptance at age six. Perceived peer acceptance at age six effected school adjustment at age seven. Lastly, perceived maternal acceptance and peer acceptance at age six had a serial mediation effect between maternal warmth at age five and school adjustment at age seven. Conclusion/Implications: Perceived social acceptance during preschool years should be emphasized in order to promote school adjustment for first grade children. Parent education for promoting better parent child relationships should be considered and teachers should encourage peer play interaction to help children perceive acceptance from their peers.

Most Korean companies in the fashion industry are SMEs, and the role of the CEO and management ownership is important for enhancing the firm's competence and developing strategies. The study aims to examine the effect of management ownership on company financial growth. In particular, the study focuses on the moderating effect of company age and size on Korean fashion SMEs' financial outcomes. Financial data based on company financial statements from 2012 to 2014 was collected by the Data Analysis, Retrieval and Transfer System of Korea's Financial Supervisory Service. A total of 295 companies' (domestic fashion businesses) data was analyzed by the bootstrap method. The median sales value in the financial year 2014 was 47,492,403,958 KRW, and the company size was divided by it. The companies were in business for an average of 20 years. According to the results, the management ownership had a negative effect on Compound Annual Growth Rate (CAGR) for the three-years, and the relationship between the two variables was moderated by company age. Additionally, the interaction effect of management ownership and company age on 3-CAGR was also moderated by company size. When the companies had spent only a few years in business, a negative effect of management ownership for small firms and a positive effect of management ownership on financial growth for medium firms were found. These results suggest that small companies starting business need to manage their company governance structure to make flexible decisions, and after retaining financial growth, the companies can expand their businesses based on strong ownership.

The competition to acquire customers with repurchase intention is getting more and more intense in the saturated smartphone market. That is why the aim of this study is to investigate the difference in purchasing determinants between various age groups and gender. Furthermore we aimed to analyze which of the purchasing determinants influence repurchase intention. In order to gather information we conducted a survey on 252 respondents. We selected 5 purchasing determinants (A/S, H/W, switching cost, network effect and design) by conducting factor analysis and validity analysis. Then we analyzed how respondents of different age groups and gender perceived different purchasing determinants and analyzed the influence purchasing determinants have on repurchase intention. As for analyzing the difference of purchasing determinants throughout various age groups, the H/W, A/S, network effect showed a notable difference. The older respondents tended to consider H/W, A/S, network effect more importantly than younger respondents. When it came to comparing the results depending on the gender, male respondents tended to consider H/W factor more importantly compared to female respondents and the opposite was true for other factors such as A/S, switching cost, design, and network effect but there weren't any significant differences. Finally, out of various determinant factors, network effect and design turned out to have a considerable influence on repurchase intention. That is why it would be highly appropriate to say that if a company intends to boost repurchase intention, enhancing network effect and developing an effective design would be crucial. This study differs from other existing researches in that we analyzed respondents from different age groups and gender separately. Also unlike other researches we directly analyzed the influence purchasing determinants have on repurchase intention not customer satisfaction. This study is expected to serve as basic information that can be used to establish strategies both in an academic and practical level, allowing companies to boost the repurchase intention of the smartphone market.

의료 기술의 발달로 수명이 연장됨으로써 노년기에 어떻게 행복한 생활을 영위할 수 있는지에 대한 관심이 커지고 있다. 그런데 연령대에 따라 행복감에 영향을 미치는 변인의 유형이나 행복에 대한 변인의 영향력이 변화할 수 있기 때문에 이에 대해 실증적으로 조사하는 연구가 필요하다. 선행연구를 통해 조절초점 중 '향상초점'을 활용하는 개인이 '방어초점'을 활용하는 개인보다 대체로 행복할 가능성이 높다는 것이 발견되었다. 그러나 이와 같은 조절초점의 영향이 사람의 전생애동안 모든 연령대에 걸쳐서 유효한 것인지에 대해서는 아직 조사가 제대로 이루어지지 않았다. 따라서 본 연구에서는 거주지역과 연령대별로 성인 1250명을 무작위로 선정하여 표집을 구성하고 연령이 조절초점과 주관적 행복감 간의 관계에 대해 유의한 조절효과를 가지는지 검증하였다. 분석 결과, 향상초점과 연령은 주관적 행복감에 대해 유의한 상호작용 효과를 가진 것이 발견되었으나, 방어초점과 연령은 유의한 상호작용을 보이지 않는 것으로 나타났다. 보다 더 구체적으로 연령이 높아질수록 향상초점이 삶의 만족도와 정서균형에 미치는 정적 영향이 더 강해지는 것이 발견되었다. 본 연구결과는 노년기에 능동적으로 도전적인 목표를 설정하고, 자발적으로 동기를 부여하며 성취감을 느끼는 등 향상초점을 활용하는 것이 주관적 행복감을 경험하는 데 더 중요한 역할을 한다는 것을 시사한다. 또한 본 연구에서는 사회적 지원체제의 구축을 통해 노인의 향상초점을 활성화할 것을 제안한다.
