This study investigated the effects of inclusion of pollock oil (PO) in the diet of broodstock on the egg and larval quality of Walleye Pollock Gadus chalcogrammus. The experimental diet comprised of semi-moist pellets prepared either with or without PO (control; Con). The fish assigned to each diet were fed to visual satiation (two meals per day) for 12 weeks. Eggs spawned from both groups of fish were sampled during the spawning season (three months) and the egg and larval quality was determined. Total egg volume, fertilization, and hatchability of eggs from the PO group were higher than those of the Con group. Fatty acid composition of fertilized eggs was not affected by the experimental diet. Oleic acid, eicosapentaenoic acid, and docosahexaenoic acid content in larvae of the PO group was higher than that in larvae of the Con group. These results demonstrate the beneficial effects of including PO in the broodstock diet of Walleye Pollock, specifically on the quality of the eggs (total egg volume, fertilization, and hatchability) and larvae (fatty acid composition).

When the clamp meter approaches the electric path where current is flowing, leakage current can be measured at a distance from the electric current because the induced current increases as the magnitude of the current increases and approaches nearer to the electric path. Therefore, measurements were carried out from a distance to avoid this effect. In addition, the measured values differ depending on the location of the power line that penetrates the ZCT of the clamp meter, thus measurements were performed at a location where this effect was minimized. The fraction of compliant branch circuits, whose leakage current was lower than 1.00 mA, was found to be 69.0% out of the total of 439 branch circuits, while the percentage of compliant branch circuits having an insulation resistance higher than $0.20M{\Omega}$ was found to be 93.2%. The reason why the percentage of compliant branch circuits with low leakage current was low might be due to the inclusion of capacitive leakage current in the total measured leakage current.

본 연구의 목적은 체조심판의 스트레스 요인과 대처방식을 규명하는 것이며 이러한 연구결과는 체조심판의 교육방안 제시에 기초자료로 제공될 것이다. 연구 대상자는 현재 심판으로 참여하고 있는 남성 체조심판 100명, 여성 체조심판 74명으로 총 174명이다. 본 연구의 목적을 달성하기 위하여 예비조사와 본조사를 실시하였다. 체조심판의 성(性)에 따른 스트레스 요인과 대처방식의 차이를 검증하기 위하여 t 검증을 실시하였다. 또한, 체조심판의 연령, 심판경력, 연간 심사빈도, 본업에 따른 스트레스 요인과 대처방식 차이를 검증하기 위하여 일원변량분석(one-way ANOVA)을 사용하였으며, 체조심판의 스트레스 요인과 대처방식의 관계를 밝히기 위해 상관분석을 하였다. 연구결과로 체조심판의 스트레스 요인은 성과심판경력에 따라서 차이가 있었고 스트레스 대처방식은 성(性), 연령, 심판경력, 연간 심사빈도에 따라 차이가 있었다. 또한 체조심판의 스트레스요인과 대처방식의 하위요인간에는 대체적으로 정적인 상관관계가 있다. The purpose of this study was to examine sources of gymnastic judges` stress and coping styles. The participants of this study was those with qualification for gymnastic judge(artistic gymnastics) in Korea. Questionnaires distributed to all the 230 gymnastic judges, and selected 174 respondents who gave valid replies(male = 100, female = 74). In order to identify the sources of stress and coping styles recognized by gymnastic judges during their judging work, present study analyzed differences based on gender, age, judging career, yearly frequency of judgment and principal occupation. Analyzed through frequency analysis, independent sample t-test and one-way ANOVA, and correlations. Conclusions drawn from the research method and procedure above are as follows. First, sources of gymnastic judges` stress was different based on their gender and judging career. Second, gymnastic judges` coping style of stress was different based on their gender, age, judging career and yearly frequency of judgment. Finally, there were generally positive correlations among sources of gymnastic judges` stress and coping styles.
농촌노인의 일과 여가활동이 심리적 복지감에 미치는 영향
이정화(Lee Jeong Hwa),한경혜(Han Gyeong Hye) 한국농촌사회학회 2003 農村社會 Vol.13 No.1
농촌에서 노인의 인구비중이 높아지고 이들의 삶의 질이 중요하나 지금까지 농촌노인들의 삶의 질이나 심리적 복지에 대한 연구는 도시에 비해 매우 적었다. 특히 정년의 개념 없이 지속적으로 생산활동을 유지하고, 대부분 그 지역사회에서 오랜 기간 사회적 관계를 유지하며 살아가는 농촌노인들은 도시노인에 비해 다양한 사회적 관계망과 사회적 활동을 더 오랫동안 유지할 가능성이 높지만 이러한 사회적 활동들이 농촌노인의 심리적 복지감에 어떠한 영향을 미치는지에 대해서는 많이 알려지지 않고 있다. 본 연구는 농촌노인들의 사회적 활동영역중 농사일참여와 여가활동을 중심으로, 사회적 활동에의 참여가 농촌노인의 심리적 복지감에 미치는 영향을 살펴보고자 하였다. 본 연구자료는 제주도를 제외한 8개 도 32개 시·군에서 1개 마을씩을 선정하여 총 1,226명의 농촌노인을 대상으로 생활지도사가 면접한 것이다. 자료분석은 Spss windows 10.0을 이용하여, 빈도, 백분율 등의 기술통계와 교차분석, 피어슨의 적률상관계수, 중다회귀분석의 통계기법을 사용하였다. 농촌노인의 일반적 특성, 농사일 참여정도, 여가활동 참여정도가 심리적 복지감에 미치는 영향을 살펴본 결과 농사일 참여정도는 농촌노인의 심리적 복지감에 설명력이 나타나지 않은 반면, 여가활동 참여정도는 이에 정적으로 영향을 미쳐 여가활동 참여가 농촌노인의 심리적 복지감을 증진시키는 것으로 나타났다. 노년기 생산적 활동이 노인들의 심리적 복지에 긍정적이라는 기존의 연구결과와 달리, 농촌노인들의 경우 농사일 참여는 그들의 심리적 복지에 영항을 미치지 않았다. 이는 `농사일`이 농촌 노인에게 생산성이라는 의미를 부여할 수 있는 활동이라기보다는 경제적 필요에 의해 `해야만 하는 일`로서 비자발적인 측면이 부각되었기 때문이거나, 농촌노인들이 감당하기에 너무 고된 일이었기 때문으로 해석할 수 있다. 또한, 사회경제적 특성을 통제하고서도 여가활동에 참여하는 정도가 높은 노인일수록 심리적 복지감이 높았다는 결과는 여가가 갖는 긍정적인 의미를 다시 보여주는 것으로, 농촌노인의 여가활동 참여를 더욱 활성화 시켜야 할 필요가 있음을, 그리고 이를 위해 농촌노인들이 쉽게 접근할 수 있고 이용 가능한 여가 프로그램이 많이 개발·보급되어야 함을 시사한다. In Korea, as the elderly population is growing, the quality of life of the rural elderly is becoming a major concern. According to Rowe and Kahn(1997), active and productive engagement in society is a central component of successful aging. Yet, the effect of various social participation on psychological well-being is not uniform. For ex. involuntary participation for productive activities due to economic needs might have negative impact on psychological wellbeing. Likewise, involuntary leisure after the forced retirement could not be enjoyable for the elderly. However, few empirical research was done to examine the effect of work and leisure activity on psychological well-being of the elderly people. This study is an attempt to empirically examine the connection between them. For this purpose, community welfare specialists gathered data from 1226 rural elderly in 32 villages, using structured questionnaires. The statistic methods used for the data analysis were descriptive statistics, cross tables and hierarchical regression analysis using spss wins10.0program. The major findings of this study were as follows: It was found that the majority of rural elderly engaged in farming and 62.8% among them are heavily involved in that profession. The mean of daily working hours of the rural elderly during the busiest season for farmers was 7.8 hours. The main reason for their continued participation in farming was economic need. In terms of leisure activity, about 40% of rural elderly participated in various activities in the community. The main activities were participating in the programs offered by community senior centers and visiting neighbors or friends. The effects of farming and leisure activities on the rural elderly`s psychological well-being was different. That is, the extent of leisure activities positively affected their psychological well-being while extent of farming didn`t show significant impact.

As the proportion of the elderly population in rural area is growing repidly, the quality of life of the rural elderly is becoming a major concern. According to Rowe Kahn(1997), active and productive engagement in society is a central component of successful aging. Yet, the effect of various social support network on psychological well-being of the rural edlerly is not well known. This study is an attempt to empirically examine the connection between social support network and psychological well-being of the rural elderly. For this purpose, community welfare specialists gathered data from 1033 rural elderly in 32 villages, using structured questionnaires. The statistical methods used for the data analysis were descriptive statistics, cross tables, ANOVA and hierachical regression analysis using spss wins 10.0 program. The major findings of this study are as follows: The majority of rural elderly have social support networks composed of more than one person and the mean number of their social support network ten persons. The elderly who keep frequent contact than one person and the mean number of their social support network was ten persons. The elderly who keep frequent contact with many adult children and friend/neighbor are happier than the elderly who keep contact with fewer number of children and friends. The size of the network of relatives significantly affects the level of loneliness of the elderly. Theoretical and practical implications of the quality of life of the rural elderly is discussed.
