The purpose of this study is to compare the physical, psychological, and social well-being of elderly women living in rural areas depending on their participation in swimming activities. Study sample consisted of 41 elderly women residing in the G province of C region who participated in swimming activities at least 3 times per week for one or more years, and 43 elderly women of the same area who did not participate in swimming activities. Data was collected over the course of 6 weeks. Analysis of the data showed that there are significant differences between participants and non-participants of swimming activities in their physical well-being(pain, flexibility), psychological well-being(perceived health status, depression), and their social well-being(strengthened interpersonal relations). In other words, participants of swimming activities, compared to non-participants, were in better physical, psychological, and social conditions. Thus, active encouragement and support must be in place for elderly women in rural areas to engage in swimming activities by utilizing local swimming facilities.

The purpose of this study was to investigate the effects of 12-weeks' swimming training on BMI, leptin and plasma lipid profiles in limited exercise function and physical activity with cerebral palsy. Swimming training program is scheduled to perform for 12-week and 1h each 4 or more times per week. The results of the this study were as follows; First, Body weight, BMI, total cholesterol, LDL and leptin were slightly decreased trend, although these did not reach statistical significance. HDL was not changed in before vs. after training. Second, in the concentration of plasma triglyceride, after training was significantly higher than before training(p<.05) and free fatty acid level was significantly lower at the after training(p<.001). These results suggest that the 12 weeks' regular swimming program has effect of improving plasma lipid and leptin levels in cerebral palsy. Therefore, we consider that it have effect on prevention of obese-related metabolic diseases in cerebral palsy.

Magnesium ($Mg^{2+}$) is an essential co-factor for over 325 physiological and biochemical processes so that plays a central role of neuronal activity, cardiac excitability, neuromuscular transmission, muscular contraction, vasomotor tone, and blood pressure significantly related to physical performance. However, only limited information on blood ionized $Mg^{2+}$ ($iMg^{2+}$) regarding to physical exercise is available and the data from blood total $Mg^{2+}$ detection are inconsistent. This present study investigated the changes of blood $iMg^{2+}$ correlated with metabolic demands during acute high-intensive exhaustive physical exercise in rats. After exhausted swimming (3-4 hours), blood pH, glucose, $HCO_3{^-}$, oxygen and ionized $Ca^{2+}$ ($iCa^{2+}$) were significantly decreased, whereas lactate, carbon dioxide, $iMg^{2+}$, ionized $Na^+$ and ionized $K^+$ were significantly increased. During the exhausted swimming, the changes in $iMg^{2+}$ showed a significant negative correlation with changes in pH, glucose, $HCO_3^-$ and $iCa^{2+}$, however a significant negative correlation with changes in lactate and anionic gap. It is concluded that the acute high-intensive exhaustive physical exercise could produced hypermagnesemia, an increase in blood $iMg^{2+}$ via stimulation of $iMg^{2+}$ efflux following increase in intracellular $iMg^{2+}$ from muscle induced by metabolic and respiratory acidosis.

The purpose of this study was to identify the characteristics of health-related indicators according to the participation of swimming program by adults with intellectual disabilities(ID). To this end, 20 adults with IDs, aged 20-39 living in Busna, were selected. Participants divided into two groups: swimming program participation(n=10) and non-participation(n=10). Data were collected by measuring the subjects health-related physical fitness, stress hormones, and immune function and data analysis was conducted using SPSS 18.0, paired t-test, independent t-test and two-way ANOVA. As a result, muscle strength(p<.001), muscular endurance(p<.001), flexibility(p<.001), cardiovascular endurance(p<.01) improvement of exercise group significantly but there was no significant difference in the control group. The stress hormone cortisol(p<.01) was significantly decreased in the exercise group and there was no significant difference in the control group. The immunoglobulins, IgA(p<.05), IgG(p<.001), IgM(p<.05) were significantly increased in the exercise group, but not significantly different in the control group. Therefore, regular swimming program can be said to be a very effective exercise program for improving the physical fitness of adults with IDs, and it is thought that it can reduce stress and help improve immune function. This suggests the need for active physical activity program development and intervention to maintain the health of adults with IDs and prevent chronic diseases.

도시하천은 급속한 경제성장과 개발 등 여건변화에 따라 크게 변화되어왔다. 이에 하천은 본연의 모습과 가치를 잃고 인공적인 모습으로 변해 하천의 주요 기능인 자정작용, 생태계 건강성 유지 등의 기능을 잃고 도시 활동에 따른 오염물질에 노출되어가고 있는 실정이다. 이로 인한 부정적인 영향으로 도시민의 삶의 질과 만족도 또한 하락되고 있다. 본 연구에서는 부산의 대표하천인 수영강을 대상으로 도시하천 수질 개선을 위한 도시민의 지불의사를 추정하였다. 비시장가치를 추정하기 위해 조건부가치측정법(CVM, Contingent Valuation Method)을 적용하여 수질개선에 따른 지불의사(WTP, Willingness To Pay)를 파악하고 경제적 가치를 추정하였다. 가상시나리오는 EPA, water quality ladder의 개념을 이용하여 현재 수영강 수질이 오염된 물(4등급)이라고 가상시장을 설정하고 낚시가 가능한 수준(2등급)까지 개선을 시키고자 할 때의 지불의사를 물었다. 이때 지불수단은 기부금의 형태로 연 1회 향후 5년간 지불기간을 설정하였다. WTP 모형추정은 KDI에서 제시하고 있는 로지스틱분포 함수와 스파이크 모형을 사용하여 WTP를 추정하였다. 스파이크 모형의 추정결과 평균 지불의사액은 12,255원으로 부산광역시 전체 가구 수인 1,392,291가구(2019년)에 적용할 경우 향후 5년간 연 170억 원의 재원을 확보할 수 있는 것으로 나타났다. 지불의사 추정결과 수영강 인접 지역주민의 지불의사가 높게 추정되었고, 부산시민이 수영강을 자연과 생태보전 기능하천으로 인지하고 있음(56.5%)을 고려 할 때, 하천환경개선을 통한 지불의사의 상승은 도시하천 가치 향상이 될 수 있을 것으로 판단된다. 또한 도시민의 기대수준 충족과 더불어 도시하천 가치상승을 위한 부족한 재원까지도 조달 할 수 있는 방안의 기초를 마련 할 수 있을 것이라 판단된다.
