Objective: The purpose of the study is to evaluate appropriate weight for aged farmers in manually handling livestock feed in bags using ergonomic methods. Background: In the livestock industry in South Korea, despite the trend of aging of labor manpower, heavy items are still manually handled in many farms. In particular, among stockbreeding works, the handling of feed in bags weighing 25~30kg is reported as a cause of frequent injuries and musculoskeletal system diseases. However, studies on the standard for recommended weight allowed considering the physical characteristics of aged farmers older than 60 years with greatly decreased physical strength and muscle strength are insufficient. Method: To evaluate appropriate weight for handling of heavy livestock feed in bags, physical techniques for measuring recognized levels of physical work loads, the NLE (NIOSH lifting equation) a method that is an observation type technique, and an ergonomic modeling technique to predict compressive force imposed on L5/S1 were used. Subjects who participated in the experiment were organized into two groups of males/females with mean age exceeding 60 years, and lifting tasks were evaluated for nine weight levels. Results: Based on the results of psychophysical measurement, females showed a tendency of more drastic increases compared to males when weight was over 19kg. The results of estimation of regression models for the weight, 18.0 kg ($r^2=0.97$) and 15.3kg ($r^2=0.97$) were evaluated as stable load for males and females, respectively. In addition, both the observation type evaluation and ergonomic model evaluation showed stable loads in a range of 15~18kg. Conclusion: Given the results of the study, the weight of the feed in bags currently distributed to farms can become a cause of not only overexertion but also farm work related disasters such as musculoskeletal disorders and safety accidents. Providing livestock feed in bags weighing not more than 19kg for aged farmers is judged desirable, and managerial improvement for this matter is considered necessary. Application: The results of the present study can be utilized as useful data for institutional improvement of the weight of livestock feed in bags.

본 연구는 노인의 주관적 건강평가에 영향을 미치는 인구사회학적변수, 신체건강상태, 건강행태와 관련된 요인들 중 성별 차이가 존재하는지 고찰하는 것이 목적이다. 이러한 연구목적을 달성하기 위하여 한림대학교 고령사회연구소에서 수행한 한국 노인의 삶의 질 조사 중 가장 최근 조사인 2009년 제 4차 조사 자료를 횡단면으로 분석하였다. 연구대상자는 2009년 제 4차 조사시점에서 만 65세 이상의 응답자(N=986, 남성 407명, 여성 579명)만을 선택했으며 교육수준에 대한 변수를 제외하고 모두 제 4차 조사 자료에서 변수들을 추출했다. 분석방법으로는 $x^2$ 혹은 t-test를 실시하였으며 독립변수들이 주관적 건강평가에 유의미한 영향을 미칠 때 성별차이가 존재하는지 고찰하기 위하여 남녀 집단으로 나누어 로지스틱 회귀분석을 실시하였다. 회귀계수 남녀차이의 통계적 유의도를 검증하기 위해 Wald $x^2$ 으로 분석했다. 연구결과로는 회귀계수의 남녀차이 검증에서 두 집단 간의 차이를 야기한 변인들은 연령(75-84세), 교육수준, 도구적 일상생활수행능력이었으며 특히 교육수준은 여성에게 긍정적으로 영향을 미치는 것으로 나타났다. 그러나 주관적 경제상태는 남성과 여성 각각의 집단에서는 주관적 건강평가에 유의미한 영향을 미쳤지만 그 유의미한 영향이 남녀 간에는 차이가 없는 것으로 나타났다. 신체건강상태에서는 도구적 일상생활수행능력에서 도움이 필요한 여성이 남성에 비해 더 자신의 건강을 부정적으로 인식했다. 인구사회학적 변인들, 신체건강상태, 건강행태 변인들 중 주관적 건강평가 시 남녀의 차이를 야기하는 변인들을 중심으로 정책지원이 이루어져 건강을 유지하고 관리하는데 남녀 간의 간극을 좁힐 수 있도록 하고 더 나아가 자신의 건강을 긍정적으로 인식할 수 있도록 변화시켜 나갈 필요가 있다.

This study has been performed to explore conveniences and inconveniences of daily lives in rural residential care facilities among the elderly residents. In this study, five males and seven females aged 68 to 78 were asked about socio-familial and physical aspects of their daily lives in the facilities such as meals, social activities, family visits, recreation, and health care. The answers of the qualitative interview were drawn as follow; first, the residents perceived well planned regular meals and snacks, free visits of friends, regularly supervised daily sanitary activities, periodic outdoor activities, education programs provided by religious experts, and pastoral farming lives as most convenient aspects of the retirement facilities. In addition, some felt that facility life made them free of familial conflicts, while others appealed fear of being forgotten because of distant location. On the other hand, they perceived the supervised group activities and meals as major inconveniences. They also felt persistently depressed when closely observing serious illness or deaths of their co-residents. Therefore in this study, suggestions were made as follows: first, combination of normal family life and retirement facility should be developed in the mixed form of community welfare center and shared home. Second, intensive medical care facilities should be in collaboration with the retirement facilities, so that the residents are relieved from stressful contacts with extremely ill patients in the residential area.

The purpose of this study was to determine the effect of intramuscular stimulation (IMS) therapy in older persons with musculoskeletal pain. The subjects were 181 older persons (54 males, 127 females) with musculoskeletal pain. Intramuscular stimulation unit with needles (size $.3{\times}30$ mm) was applied for the treatment. The analgesic effects were measured by visual analog scale (VAS). Results showed that the post-treatment VAS score was significantly decreased after IMS therapy for fifteen minutes compared to pre-treatment score. In addition, the post-treatment VAS score was significantly decreased in patients with chronic pain (pain duration of one year after onset) compared to the post-treatment VAS score in patients with subacute pain (pain duration less than three months after onset). There was no significant difference in analgesic effects according to gender and age groups. It is determined from this study that IMS therapy can be beneficial for patients with chronic musculoskeletal pain in clinical setting. Further study is needed to identify whether the IMS therapy can change the pain threshold in patients with neurologic pain.

In Sasang constitutional medicine, doctors diagnose and treat patients according to their Sasang consitutition (SC) type. In this work, by a clinical test with a radial pulse tonometer, we investigated radial pulse properties which were significant in distinguishing unhealthy subjects from healthy subjects for each SC type. We measured radial pulse properties on left and right Gwan locations with a pulse tonometer for 299 elderly female subjects of age of 50 years old or above. We used a newly developed SCAT system to determine subjects' SC types. Subjects' health levels of either healthy or unhealthy were determined independently by two Korean medical doctors. To investigate the statistical differences, we used either of Student's t-test or Mann-Whitney U test depending on the normality of distribution of test statistic. For TE type, unhealthy subjects were characterized with significant increases in heart rate, systolic to diastolic period, pulse depth, while they showed significant decreases in width of pulse in normal direction, pulse area in diastolic period, and high harmonic components (6th, 7th) of power spectral density. For SE type, unhealthy subjects were characterized with significant increases in pulse pressure and pulse depth, while no significant differences were found for SY type. We investigated the characteristic differences in radial pulse properties due to change in health levels on each SC type for elderly females. Pulse variables which were significantly different between healthy subjects and unhealthy subjects were found to vary between SC types. For TE type subjects, many variables were found significant at the left Gwan location, which is in support of the theory of hyperactive liver functioning for TE type. Irrespective of the constitution, the related changes in the pulse properties due to worsened health level were in support of elevated blood flow amount in compensation with weakened blood circulatory function.
