본 연구에서는 중·고령자의 다양한 사회활동 참여가 치매 진단의 1차적 기준이 되는 인지기능에 미치는 영향을 살펴보았으며 이를 위해 2006년 고령화 연구패널 자료를 활용하여 만 45세 이상 중·고령자들의 사회활동 참여와 인지기능 점수간의 관계를 분석하였다. 사회활동의 유형은 김영범·이승훈(2008)의 연구에서 정의한 종교활동, 여가활동, 공공집단 활동과 연고집단 활동으로 분류하였으며 인지기능을 측정하는 MMSE-K의 원점수를 분석에 사용하였고 사회경제수준과 건강수준을 통제변수로 사용하였다. 만 45세 이상 중·고령자 전체를 분석한 결과 종교활동과 여가활동이 인지기능에 유의한 영향을 주는 것으로 나타났으며 연령과 성별을 층화하여 중년 남성, 여성집단과 고령 남성, 여성집단으로 분석한 결과 중년 남성집단에서는 여가활동이 유의하였으며 중년 여성에서는 4가지 사회활동이 모두 유의하지 않았다. 고령 남성과 여성에서는 종교활동과 여가활동이 모두 인지기능에 유의한 영향을 주는 것으로 나타났으며 고령 여성의 공공집단 활동 참여가 인지기능에 유의한 영향을 미치는 것으로 나타났다. 연구의 결과를 통해 중년자들의 사회활동 참여보다 고령자의 종교활동과 여가 활동의 참여가 인지기능 장애와 치매예방에 더 긍정적인 영향을 준다고 볼 수 있으며 이를 근거로 노인들이 건전한 여가활동을 누릴 수 있도록 체계적인 정책과 지원의 확대가 필요하다는 것을 확인하였다.

This research aims at finding out how spare time activity, relationships with their children and loneliness affect the satisfaction of life of elderly people who have no spouse. To begin, according to the survey, in the case of elderly people who have no spouse, male elderly people feel more loneliness, lower unification with their offspring, and do less activity in their spare time than female elderly people. The elderly people with a higher educational level, feel less loneliness and have a close relationship with their offspring. When elderly people believe in a religion, they participate in positive activities in their spare time and have a higher satisfaction of life. Secondly, the less the elderly people have for a monthly income, the more they feel a deep sense of isolation. However, if the elderly have a sufficient monthly income, they spend their spare time on positive activities and feel a higher sense of satisfaction in their lives. These results show that economic situation is an important factor for elderly people to maintain good mental health and a good quality of life. Thirdly, the loneliness of elderly people who have no spouse was influenced by whether the elderly people have children or not. If an elderly person loses their spouse through death, they can find themselves in a desperate situation and feeling very isolated. Most elderly people who have no spouse want to live with their offspring and depend on their sons and daughters economically and psychologically. However, the elderly people living alone have lower satisfaction of life because of economic and psychological problems. Therefore, the results shows that the life satisfaction of elderly people who have no spouse was influenced by living with their children and having a close relationship with them. The elderly people who have no spouse feel hopelessness and rely increasingly on their sons and daughters. The elderly people who don't have a sufficient monthly income not only feel more loneliness than other elderly people, but are also restricted in their spare time activities. It proves that the economic situation(monthly income) is also an important factor to maintain personal relationships.

The purpose of this cross-sectional study was to explore fear of falling in relation to activity restriction of in the community dwelling elderly. Two hundred ninety-nine community dwelling elderly residing in Seoul and Kyonggi-do were interviewed using a structured questionnaire. The results were as follows : 1. Subjects were predominantly women$(70.6\%)$, an average 72.5 years old; the incidence of falls in last one year was $45.5\%$. 2. The highest level of fear found for activity in those who say they do engage and those who do not engage in the activity was 'going out when it is slippery '(m=2.53, 2.81) and 'reach for something over your head'(m=1.66, 2.60). Fear of falling scores were significant lower for those who say they do engage in eight kinds of activities (excluded activities of given were 'go to the store', 'take a tub bath', 'get out of bed') than for those who do not engage in the activities. 3. Among those who did not perform the activity, the three activities, when it is slippy(n=80), reaching overhead(n=70), and walk outside(n=59),were most often avoided because fear alone as well as for reasons in addition to fear. 4. The significant variables associated with fear of falling were female(p=0.0000), 1 educational status(p=0.000l), poor economic condition(p=0.0007), and experience of falls in last one year(p=0.0007). Fear of falling is common in the community dwelling elderly in Korea and is associated with several demographical variables. Therefore, to prevent falls and to reduce fear of falling, further study for development of education program for the elderly is needed.

The study aimed to identify major factors related to global self-rated health of the community-dwelling elderly people in rural areas. Interviews were conducted with 433 persons over 65 years of age. The socio-economic characteristics, chronic disease status, measures of functional and mental health, life satisfaction, health-related behaviors including smoking, drinking, exercise, social activity, dietary habit, and food intakes were analyzed to determine their influence on self-rated health index. Data on food intake were obtained through the 24-hour recall method. The self-rated health of rural elderly was poor or very poor as reported by 42.6% and 52.4% of the men and women, respectively. Poor self-rated health was found to be related to elderly aged $65{\sim}74$, female, absence of work, more chronic diseases, dependence on Instrumental Activity Daily Living (IADL), higher mental unhealthy days, lower current life satisfaction, less social activity, lower dietary habit scores, lower intake of total food, fruit, eggs, fishes & shell fishes, vitamin C (%RDA), and Nutrient Adequacy Ratio (NAR). The results of the multiple regression analysis showed that poor self-rated health index is significantly associated with more chronic diseases, mental unhealthy days, gastrointestinal disease, musculoskeletal disease, less social activity, and lower intake of fruits. The results also suggested that improving the nutritional status and functional ability, and reducing the burden of chronic diseases are beneficial to the self-rated health index of the elderly.

Recently, summer temperatures have frequently been abnormal in Korea owing to global warming. In summer, a decrease in feed intake rate and biological activity were observed in Hanwoo (Korean Native Cattle), leading to lower production rates in the industry. However, the precise scale of damage was not reported as with other animals of economic value. This study was conducted to investigate the effects of birth season on birth weight in Hanwoo. Data were collected from 100 local breeding farms from 2016 to 2019. A total of 41,081 Hanwoo calves were classified and analyzed by sex, year, month, and season (March-May, spring; June-August, summer; September-November, fall; and December-February, winter) of birth. The birth weight of Hanwoo calves differed according to birth month. The average birth weight of male calves was 30.47 kg and that of female calves was 28.16 kg. Hanwoo birth weight was the highest in March-born calves and the lowest in July-born calves. The birth weights of calves born in February, March, April, November, and December were significantly larger than those of calves born in July. In addition, the birth weight of Hanwoo calves from the summer was significantly lower than that of calves born in other seasons. Furthermore, Hanwoo steer slaughter age showed a negative correlation, whereas carcass weight had a positive correlation with birth weight. In the beef cattle industry, birth weight is a very important economic characteristic that is related to growth rate. These data will contribute toward planning the reproduction of Hanwoo and analysis of changes in characteristics of economic value owing to high temperatures.

Objectives: This study was conducted in order to obtain information concerning the health hazards that may result from a 13 week inhalation exposure of n-pentane in Sprague-Dawley rats. Methods: This study was conducted in accordance with the Organization for Economic Co-operation and Development (OECD) guidelines for the testing of chemicals No. 413 'Subchronic inhalation toxicity: 90-day study (as revised in 2009)'. The rats were divided into 4 groups (10 male and 10 female rats in each group), and were exposed to 0, 340, 1,530, and 6,885 ppm n-pentane in each exposure chamber for 6 hour/day, 5 days/week, for 13 weeks. All of the rats were sacrificed at the end of the treatment period. During the test period, clinical signs, mortality, body weights, food consumption, ophthalmoscopy, locomotion activity, urinalysis, hematology, serum biochemistry, gross findings, organ weights, and histopathology were assessed. Results: During the period of testing, there were no treatment related effects on the clinical findings, body weight, food consumption, ophthalmoscopy, urinalysis, hematology, serum biochemistry, gross findings, relative organ weight, and histopathological findings. Conclusion: The no-observable-adverse-effect level (NOAEL) of n-pentane is evaluated as being more than 6,885 ppm (20.3 mg/L) in both male and female rats. n-pentane was not a classified specific target organ toxicity in the globally harmonized classification system (GHS).
