Thymoma is associated with myasthenia gravis, Pure red cell aplasia, and autoimmune diseases such as autoimmune hemolytic anemia, aplastic anemia, and hypogammaglobulinemia. It's association with aplastic anemia is rare and aplastic anemia appearing after surgical removal of thymoma is especially rare. The authors hereby report a case of aplastic anemia occuring in a patient who was diagnosed with thymoma and myasthenia gravis and had the tumor surgically removed. The patient was treated with anti-thymocyte globulin, cyclosporin, and prednisolone, and showed partial remission with hematologic improvements after 12 months.

Today, leisure activities have been a critical factor to lead to satisfactory life in our society from a personal and social perspective. The study for, up to now, to describe the correlation between leisure activities and leisure satisfaction has begun since 1970s. In the early stage of the study, main concern went to the relation of leisure activities, not to the leisure satisfaction, because of the difficulty of conception and measure. The main purpose of this paper to describe the influence of participation in the ski activities on the leisure activities on the basis of pre-performed studies that a positive participation in sports activities has improved the quality of life. To this end, this paper has explaine the relation between the frequency of participation in ski activities and leisure satisfaction as well as the relation between the period of participation and leisure satisfaction. In order to this purpose, this study targeting for 155 of university students and club involvers residing in Seoul and Kunggi province and have participated in winter sports more than a year employed the systemetric random sampling method. The method to collect data from questionnaire designed for this study is based on the sports activities-related questionnaire of the Korea Sport Science Institute(KSSI) and the measure for leisure satisfaction developed by Beard and Ragheb(1980), and translated and employed by Lee, Jong Kil. Through this method, the reliability and relevance of this study have been verified. According to the reliability of the study, The reliability(a) has shown. 726-842, which is very high. For data analysis, the frequency analysis and the multivariate analysis were employed. The reault of the study based on data analysis are as follows; First, it has been revealed that the higher the frequenty of participation in ski activities, the higher(educational, social, phychological, and physiological, and environmental) leisure satisfaction. Second, The results indicates that the longer the period of participation in ski activities, the higher(educational, social, phychological, and physiological) leisure satisfaction. Also the environmental leisure satisfaction has no relation with the period of participation from a satistical viewpoint. Based upon the analysis of the results and within limitation of this study, it was concluded that the participation in the ski activities enhances leisure satisfaction

Information network is the cyber space that is shared by many information providers and information seekers. As the information in network is richer and richer, information seekers have required the nicely arranged network. Therefore, network must be in intelligent manner to use information easily. We develope the intelligent agent system that is composed of translation agent, robot agent, information retrieval agent, mediate agent, and personal secretary agent.

It becomes common to use computers to control electronic devices and security facilities in newly constructed buildings and house. There are many home application devices in the market which can be controlled by computers. But they are expensive and managed by specialized companies. This paper is focused on personal computers which are available in most homes and can be used to control home electronic appliances and home security facilities. We implemented a home automation server based on Linux. The standard parallel port of personal computer is used to connect sensors and actuators. Therefore, the cost of the server is very low. Moreover, the server is connected to Internet and anywhere we can control and monitor the home security facilities and home automation systems.

The purpose of this study was to increase a efficiency on physiological reaction and putting ability of golfer when they were used Binaural-beat. Participants were fourteen man aged 21-27 years in university golfer. They were tested both before and after Binaural-beat by EEG, EMG, Heart Rate and putting of three times at 4m range. The results as follow: 1. Alpha wave was a statistical significantly increased, beta and theta wave were not statistical significantly increased when it apply the Binural-beat. 2. EMG on apply the Binural-beat was lower than meditation. Especially, there were statistical significantly difference in Trapezius and Erector spinae, were not statistical significantly difference in Tibialis anterior. 3. There was no statistical significantly difference in heart rate when it apply the Binural-beat. As this results, We Binural-beat training was given a positive influence in brain alpha wave and lower of muscles activity. Therefore, we think that it can help to concentration elevation.

Adult polycystic kidney disease(APKD) usually accompanies with renal and extrarenal manifestations and liver cysts are present in aproximately 30% of patients with APKD. Kidney cysts often accompany with hemorrhage, rupture, infection, however, liver cysts are usually asymptomatic and do not impair liver function. Rare complication of liver cysts in patient with APKD include portal hypertension with bleeding esophageal varices and hepatic failure with encephalopathy. But, in APKD patient, infection of liver cysts without infection of renal cysts is extremely rare. We report a case of infected liver cyst in a patient with APKD who has complained generalized abdominal pain and high fever which was confirmed by ultrasound and aspiration. The patient was treated successfully with repeated aspiration and systemic antibiotics.
고지방식이가 백서 골격근 및 지방조직의 지방분해에 미치는 영향

연구배경:지방산화의 증가가 골격근에서 인슐린 저항성을 유발한다는 주장이 꾸준히 제기되어 나왔으나, 최근 제2형 당뇨병 환자나 인슐린저항성 상태에서 골격근의 지방산화능이 저하되어 있다는 보고도 있어 논란이 있는 상태이다. 본 연구에서는 고지방식이를 투여하여 인슐린저항성을 유발한 백서에서 microdialysis 기법을 이용하여 조직내의 지방분해 결과로 간질액내로 방출되는 글리세롤 농도를 골격근 및 지방조직에서 직접 측정하여 지방분해의 변화를 알아보고자 하였다. 방법:정상 SpragueDawley 백서를 두 군으로 나누어 4주간 고지방식이 및 저지방식이를 투여하였다. 4주간 기저상태 및 고인슐린 정상혈당 클램프 중의 골격근 및 지방조직에 microdialysis probe를 삽입하고 일정한 농도의 글리세롤을 포함하는 dialysate를 통과시켜 주입액과 유출액의 글리세롤 농도 차이로부터 조직 간질의 글리세롤 농도를 산출하엿다. 결과:기저상태에서 골격근 및 지방조직 간질의 글리세롤 농도는 저지방식이군에 비하여 고지방식이군에서 유의하게 낮았다. 고인슐린 정상혈당 클램프 중에는 골격근 및 지방조직 간질의 글리세롤 농도가 양군에서 모두 억제되었는데, 기저 상태와 마찬가지로 골격근 및 지방조직 모두에서 저지방식이군보다 고지방식이 군에서 더 낮았다. 기저 상태에 대한 고인슐린 클램프중의 글리세롤 방출 억제 정도는 저지방식이군에 비하여 고지방식이군에서 덜 억제되는 경향을 보였는데, 골격근조직에서만 통계적으로 유의하였다. 결론:본 연구 결과는 고지방식이에 의한 인슐린저항성 모델에서 골격근 및 지방조직내 지방분해가 억제되어 있음을 보여주며, 기존의 포도당지방산 cycle 이론과는 달리 조직내 지방산화의 증가보다는 지방산화능의 감소에 따른 세포내 지방축척이 인슐린저항성과 관련될 가능성을 시사하였다. Background : It has been hypothesized that increased fat oxidation reduces glucose utilization in skeletal muscle, and is responsible for the insulin resistance associated with obesity or high-fat feeding. In contrast, there have been reports that fat oxidation capacity was decreased in skeletal muscles from insulin resistant subjects. This study was undertaken to examine whether insulin resistance in high-fat fed rats is associated with increased lipolysis in skeletal muscle and adipose tissue. Methods : Two groups of Sprague-Dawley rats were fed either high-fat or low-fat diets for 4 weeks. Lipolysis in skeletal muscle and adipose tissue was determined by measurement of interstitial 1 glycerol concentrations by a microdialysis method in basal and hyperinsuline mic-euglycemic clamp conditions. Results : In basal state, plasma glycerol levels and interstitial glycerol concentrations of skeletal muscle, and adipose tissue were lower in high-fat fed than in low-fat fed rats. The degree of suppression of glycerol release by the hyperinsuline mia was smaller in the high-fat diet than in the low-fat diet group. However, plasma and interstitial glycerol concentrations during the hyperinsuline mic euglycemic clamps were also lower in the high-fat diet group. Conclusion : Lipolysis was decreased in skeletal muscle and adipose tissue of insulin resistant, high-fat fed rats. These results support the idea that limited fat oxidation capacity resulting in lipid accumulation in tissues, rather than increased fat oxidation perse, is responsible for the insulin resistance associated with high-fat feeding (J Kor Diabetes Asso 24:641~651, 2000).
