The purpose of this study was to collect basic data for the development of oral health education program of parents and to encourage their actual interest and participation in school oral health program. The authors surveyed parents' awareness and behaviors about the oral health of their children. The subjects in this study were 193 parents of elementary school children in Seoul. The collected data were analyzed, the obtained results were as follows: 1. Thirty-five percent of the parents investigated paid a regular visit to a dental clinic. The must common tooth brushing time among them was after dinner, the second was after breakfast, and this was followed by before bedtime and before breakfast. 2. Ninety-four percent of the parents responded that prevention is necessary, 92.2% had a plan to visit a dental clinic to prevent dental caries, and 60.1% experienced receiving pit and fissure sealants. Ninety-seven percent responded that they did check their children's dental caries. 54.9% chocked their children's oral status after tooth brushing. The parents who visit a dental clinic on a regular basis were more likely to check their children's teeth after tooth brushing than those who don't(P<0.05). 3. Eighty eight percent of respondents wanted to keep the fluoride mouth rinse program. 4. It is recommended that an oral health education program be developed for parents to visit dental clinics on a regular basis, to educate as to the right tooth brushing time, and to check out their children's oral status after tooth blushing.

The purpose of this study was to collect basic data for the development of effective oral health education program in elementary school. The subjects in this study were 604 fourth-year, fifth-year and sixth-year students of an elementary school in Seoul. Oral health awareness and behaviors were surveyed and analyzed. The findings of this study were as follows: 1. The most common time for toothbrushing was after dinner(62.0%) and before bedtime(62.3%). By school year, the largest number who brushed their teeth after dinner were fourth and fifth graders while the greatest number who did so after breakfast were sixth graders Seventy-four percent of respondents brushed the teeth twice or more a day. By school year, the fifth-year students brushed their teeth the least while girls outperformed the boys in daily toothbrushing frequency(p<0.05). Regarding the intake of cariogenic food, 62.1% took that kind of food once or more a day. By school year, the fifth graders took the most (p<0.05), and girls took more cariogenic food than the boys(p<0.05). 2. Ninety percent of the respondents had visited a dental clinic. By grade, the sixth-year students had visited a dental clinic more frequently and girls more frequently than boys. Eighty percent of the respondents visited a dental clinic to receive treatment but just 12.3% visited a dental clinic to prevent oral diseases. Concerning the fetor of dental treatment only 14.4% expressed fear. School year made no difference, yet the percentage of girls who experienced fear was higher than that of boys(P<0.05). Regarding preventive treatment, 39.7% experienced pit and fissure sealing and 24.2% experienced the application of fluorides. All the students hadn't much experience in preventive treatment regardless of school year -- gender didn't make a difference. 3. Fourty-six percent of respondents had a preference for the fluoride mouth rinsing program; 38.4% wanted that grogram to continue. As to the reason for preference, 38.2% preferred it because of the prevention of dental caries, 43.0%, the largest percentage, didn't favor it because they found it too much trouble to do(some of the respondents gave two different answers). 4. Despite an increase in the frequency of toothbrushing at the right time, they still took cariogenic food frequently Their visit to a dental clinics also aimed at treatment more than at prevention, and they had very narrow experience of preventive treatment. Furthermore, the fluoride mouth rinsing program failed to draw their interest. Therefore, it is recommended that a successful real health education program should be developed.

Background: With reports on the relation between smoking and depression appearing since 1980, it has become clear that depression is one of the psychodynamics of smoking, though there has been little or no progress made in the study of whether or not there is indeed a relation between depression and nicotine dependence. Purpose: The purpose of the study was to investigate the effects of depression on the amount and period of smoking and nicotine dependence among university man student smokers. Method: In periodical examination between 14 and 21, May, 2003, using 170 university male. The CES-D(Center for Epidemiologic Studies Depression) Scale and the FTQ(Fagerstrom Tolerance Qustionnaire) were utilized to measure the level of depression and nicotine dependency. The amount of smoking was calculated based on the number of cigarette used. Result: Results indicated that depression had something to do with amount of smoking. Nicotine dependence also was related to depression but total value was relatively low. finally the period of smoking had nothing to do with depression. Conclusion: The results of this study revealed that the amount of smoking of university man student smokers was very high. Both the amount of smoking and nicotine dependence were affected by levels of depression. Accordingly psychiatric nursing access such as emotional support is needed to manage depression and decrease smoking.

[Purpose] This study is aimed at providing clear guidance on treatment and prevention of osteoporosis by comparing and analyzing some well-known methods out of drug and exercise therapies. [Methods] For this purpose, eight-week experiments (drug therapy and exercise therapy) were carried out by using rats whose menopause was induced by the removal of an ovary. In the treatment of the drug therapy, the effects of soy protein, one of the well-known alendronate and estrogen replacement therapy, were compared and analyzed. In the treatment of the exercise therapy, endurance exercise using a treadmill and resistance exercise through climbing a special cage were compared and analyzed. Based on these results, this study will be able to suggest the most appropriate way to deal with osteoporosis which requires long-term treatment. Sixty eight-week-old Sprague-Dawley female rats had a week to adapt to the new environment. After that, they were randomly divided into four groups (Sham-Sedentary; SS, ovariectomized-control; OC, ovariectomized-soy protein; OS: ovariectomized-alendronate; OA, ovariectomized-endurance exercise; OE, ovariectomized- resistance exercise; OR) before having an operation for the removal of an ovary. After surgery, the rats convalesced for a week. Alendronate (0.4mg / kg of body weight) and isoflavones (200g / 1 kg of feed) were given to two groups respectively for eight weeks. The rats in the other two groups performed resistance exercise (climbing) and endurance exercise (20 m/min; 60min/day) five days a week for eight weeks. [Results] Ovariectomy increased the body weight and body fat like menopause did. Soy protein and alendronate intake for eight weeks had no effect on body weight but reduced the body fat increased by ovariectomy to the level of the SS group. The menopause induced by ovariectomy did not affect total bone density and bone mass as well as bone density in specific areas of the body. Soy protein and alendronate intake for eight weeks did not significantly affect them either. However, the eight-week treatment with soy protein and alendronate significantly reduced the level of osteocalcin in blood. Resistance exercise more noticeably increased body weight and bone mass than running on the low-intensity treadmill but serum osteocalcin levels were notably increased in both cases. [Conclusion] These results show that soy protein which is natural produce and low-intensity, regular endurance exercise also have an effect on the treatment and prevention of osteoporosis caused by menopause.

본 연구의 목적은 등열량 중쇄지방식과 지구성 운동이 노화쥐의 미토콘드리아 생합성과 지구성 운동능력, 인슐린 저항성에 미치는 영향을 규명하는 것이다. 50 주령의 male Wistar rat을 대상으로 4주간 중쇄지방식(전체 열량의 10%)과 지구성 운동을 실시하였다. 연구 결과 집단 간 체중의 차이는 나타나지 않았다. 그러나 중쇄지방식이 집단은 유의한 체지방량의 증가를 보였고, 공복 시 혈당과 인슐린 수준이 유의하게 증가함으로 인슐린 저항성이 발생하였다. 또한 중쇄지 방식이와 지구성 운동 병행집단의 지구성 운동능력은 일반식과 지구성 운동병행집단에 비해 유의하게 낮게 나타났다. 그러나 골격근내 미토콘드리아 생합성 표지인자들은 중쇄지방식이과 지구성 운동 시 유의하게 증가한 것으로 나타났다. 요약하면 중쇄지방은 미토콘드리아 생합성을 증가시킴에도 불구하고 인슐린 저항성을 발생시키며, 지구성 운동능력을 증가시키지 않은 것으로 나타났다. 따라서 노화쥐에 있어 중쇄지방산의 사용은 신중할 필요가 있다고 생각한다. The purpose of this study was to investigate the effects of isocaloric medium-chain fat diet and aerobic exercise on mitochondrial biogenesis and endurance exercise capacity in aged rat. 50-week-old male Wistar rat were randomly assigned for 4 group (Chow; isocaloric medium-chain fat diet, MF; endurance exercise, Ex; diet/exercise combined group, Mex). After 4 weeks, body weight did not changed between groups, but visceral fat were significantly increased in MF and Mex. Fasting plasma glucose and insulin level also significantly increased in MF and Mex. Endurance exercise capacity was significantly decreased in Mex compared with Ex. In addition, endurance exercis e capacity of Mex group was s ignificantly lower than Exgroup. However, the skeletal muscle mitochondrial biosynthesis marker was significantly increased in MF, Ex, and Mex. In summary, although the isocaloric medium-chain fat diet increased mitochondrial biogenesis despite generates insulin resistance, endurance exercise capacity does not increase, respectively. Thus, the use of medium-chain fat diet needs more research for old people.

PURPOSE: The aim of this study was to identified which PPARβ/δ control PGC-1α protein stability in rat skeletal muscle by long-term endurance exercise. METHODS: shPPARβ/δ was over-expressed in rat epitrochlearis (Epi) muscle using electrical pulse-mediated gen transfer (electroporation; EPO) method. Then animal underwent 2 wk long swimming exercise. To evaluate PPARβ/δ, PGC-1α ubiquitination, PGC-1α and mitochondrial enzyme expression in rat skeletal muscle, Epi muscles were dissected 18 h post final bout of swimming exercise. RESULTS: PPARβ/δ, PGC-1α, COX I and NADH protein expression in shPPARβ/δ over-expression sedentary (Sed) skeletal muscle were significantly decreased over 55%, but PGC-1α ubiquitination was significantly increased 2.6 fold when compared to scramble (Scr) treated Sed muscle. PPARβ/δ, PGC-1α, COX I and NADH protein expression in 2 wks swimming exercise with Scr gene treated muscle were significantly increased over 2 fold, but PGC-1α ubiquitination was significantly decreased 66% when compared to Scr gene treated Sed muscle. PPARβ/δ, PGC-1α, COX I and NADH protein expression in 2 wks swimming exercise with shPPARβ/δ gene treated muscle were not increased, but PGC-1α ubiquitination was significantly increased 1.96 fold when compared to Scr gene treated Sed muscle. CONCLUSIONS: Our results indicate that PPARβ/δ controls PGC-1α protein stability in rat skeletal muscle following long-term endurance exercise.

PURPOSE: The aim of this study was to review the effects of exercise intervention on blood glucose control in obese type 2 diabetic patients. METHODS: The PubMed and KERISS search engines were used and 61 papers that met the key questions were selected. RESULTS: Exercise is an effective intervention for the control of blood glucose in type 2 diabetic patients because it does not impair glucose transport in the skeletal muscle induced by muscle contractions. Insulin resistance, which is characteristic of type 2 diabetes, is caused by decreased insulin sensitivity or insulin responsiveness. Acute exercise improves the glucose metabolism by increasing the insulin-independent signaling pathways and insulin sensitivity in the skeletal muscle, and regular long-term exercise improves the skeletal muscle insulin responsiveness and systemic glucose metabolism by increasing the mitochondrial and GLUT4 protein expression in the skeletal muscle. CONCLUSION: The improvement of the glucose metabolism through exercise shows a dose-response pattern, and if exercise consumes the same number of calories, high intensity exercise will be more effective for the glucose metabolism. On the other hand, it is practically difficult for a patient with obese type 2 diabetes to control their blood glucose with high intensity or long-term exercise. Therefore, it will be necessary to study safe adjuvants (cinnamic acid, lithium) that can produce similar effects to high-intensity and high-volume exercises in low-intensity and low-volume exercises.

본 연구의 목적은 젊은 쥐와 중년 쥐를 대상으로 사다리 등반 운동이 골격근 내 PGC-1α의 발현과 미토콘드리아 생합성에 미치는 영향을 규명하는 것이다. 50주령과 10주령의 수컷 Wistar 흰쥐 40마리를 대상으로 1주간의 환경 적응기간을 거친 후 좌업집단과 운동집단으로 무선 배정하였다. 사다리 등반 운동은 주당 3회 총 8주간 처치하였다. 연구결과 8주간의 사다리 등반운동은 골격근 내 AMPK를 활성화시켜 PGC-1α의 발현을 증가시킴으로써 미토콘드리아생합성을 증가시킨 것으로 나타났다. 그러나 노화에 따라 미토콘드리아 생합성의 정도는 유의하게 감소하였으며, 이는 AMPK의 활성도와 PGC-1α의 발현정도의 변화 없이 나타났다. 이상의 결과에서 사다리 등반 운동은 젊은 쥐와 중년 쥐 모두의 골격근 내미토콘드리아 생합성의 증가시키는 것으로 나타났으나, 동일한 운동을 실시하여도 운동효과는 연령의 증가에 따라서 감소하는 것으로 나타났다. The purpose of this study was to investigate effects of ladder climbing exercise training on PGC-1α expression and mitochondrial biogenesis of skeletal muscle in young and middle-aged rats. 50 weeks and 10 weeks of male Wistar rats were randomly assigned for exercise and sedentary groups after one week of adaptation period. The ladder climbing exercise training was carried out using ladder climbing with weight attached to the tail (3 days/week, 8 weeks). Ladder climbing exercise training for 8 weeks significantly increased AMPK activity and PGC-1α protein, mitochondrial enzyme activity in plantaris muscle. However mitochondrial biogenesis levels were significantly decreased in 50 weeks old rats without the change of PGC-1 level and AMPK activity. Therefore ladder climbing exercise training was effective tool to increase mitochondrial biogenesis in skeletal muscle, but training responses were found in the middle-aged rats.
