Jinhee-Twentyfour method Qigong (陳希夷二十四節氣坐功導引) is a traditional exercise which is known as qi-gong. It was first mentioned in ${\ll}$保生心鑒${\gg}$ published in Myung dynasty. But it is very difficult to know how to master Jinhee-Twentyfour method Qigong (陳希夷二十四節氣坐功導引) So we studied the training methods by analizing several books such as ${\ll}$遵生八${\gg}$ and ${\ll}$內外功圖說輯要${\gg}$ which have pictures of the training methods. It is known that to train Jinhee-Twentyfour method Qigong (陳希夷二十四節氣坐功導引) is not only limited to the exercise of the body but also training of the mind is an important factor. It is very important to know that the system of Hyung(形), Qi(氣), Sin(神) is needed for Jinhee-Twentyfour method Qigong (陳希夷二十四節氣坐功導引)

This paper considers the preventive maintenance scheduling problem of the cluster tool which is one of the most important manufacturing equipments in the next-generation semiconductor production environment. We define a random process that expresses the successive amount of chemicals accumulating inside the tool. Based on the renewal theory, we find the expected value and probability distribution of the time that the amount of accumulated chemicals exceeds a predetermined level. For a given probability that the accumulated chemicals exceeds the predetermined level we present a method to obtain the number of chamber operations to perform the preventive maintenance of that chamber. In addition, a method to get the preventive maintenance schedule for the whole cluster tool is presented. A numerical example is provided to illustrate our method.

At the Rolling-stock, most important thing is thorough maintenance for safety as a mass transit. Recently, many studies of cost down method and acquisition of high reliability have being progressed with considering of safety. Maintenance cost is closely relative to the preventive maintenance. But generally the preventive maintenance is decided in compliance with an experience. So the study of cost down method at the preventive maintenance is difficult. In this study, many results of effectiveness and optimization for the preventive maintenance are checked. Then., it is possible that efficiency preventive maintenance method will be able to suggest.

The genetically determined ability to metabolize debrisoquine (DBR) is related to risk of lung cancer and DBR hydroxylation exhibits wide inter-individual variation. In this study, 100 korean adults were tested for their ability to metabolize DBR. The DBR metabolic phenotype were determined by metabolic ratio (MR, DBR / 4-HDBR) which is the percent dose excreted as unchanged DBR divided by the percent dose excreted as 4-hydroxyebrisoquine(4-HDBR) in a aliquot of an eight hour urine sample, after 10mg DBR test dose administration. Analysis was performed on a capillary gas chromatograph fitted with electron capture detector. The results were as follows; 1 Geometric mean of DBR MR was 0.32 in male,0.27 in female,0.30 in total and the distribution of log (MR) was seemed to follow normal distribution. 2. Metabolic ratio of DBR was higher in non-smoker and non-drinker than in smoker and drinker without any statistically significant difference. 3. None of personal factors was significantly related to DBR MR except age. 4. The DBR metabolic phenotype was extensive metabolizer(EM) 93, intermediate metabolizer(IM) 7 by traditional method and EM 98, IM 3 by Caporaso's method. The poor metabolizer (PM) phenotype was not found by either method. 5. Maximal expected PM phenotype was 0.36% by traditional method and 0.04% by Caporaso's method.

Objective : This study is aimed to analyze the recent research trend of Sipjeondabo-tang (SJDBT) in Korea. Method : We searched Korean research database by using keyword 'Sipjeondabo-tang'. Databases are Korean Medicine Information System, Research Information Service System and Korean Studies Information Service System. We analyzed studies by research method, publication year, type of journal and subject of the study. Results : By analyzing studies published after 1990, we could find that experimental studies were primarily conducted in SJDBT study. During recent 10 years, the number of toxicity studies and components analysis studies is increasing. Among the SJDBT studies, the number of clinical study was only 1. Conclusion : We explored the recent research trend of SJDBT in Korea. As a result, We suggested three further research ways of SJDBT. Proposed research ways are exploring various effect of SJDBT, observing whether there is a difference of effect according to extracting and drying method, and conducting clinical research of SJDBT.

Background: Uncooperative behavior of children due to dental anxiety may interfere with the effective delivery of dental care and compromise the quality of treatment provided. Injection of local anesthesia is one of the most anxiety-inducing stimuli in pediatric dentistry. This study aimed to compare the efficacy of a child-friendly device, having a combined effect of vibration and distraction, with the conventional method of injection on pain, anxiety, and behavior of pediatric patients aged 6-11 years. Methods: This randomized, crossover, split-mouth study included 30 children requiring a bilateral inferior alveolar nerve block. The children were equally divided into two groups: group 1, aged 6-8 and group 2, aged 9-11 years. All children were injected with anesthesia using the conventional and device method in two separate sessions. They were assessed for anxiety by measuring the pulse rate before and during the administration of local anesthesia. Behavior was assessed using Faces, Legs, Activity, Cry, Consolability (FLACC) scale, and the child's experience while receiving anesthesia was assessed using the Wong Bakers Pain Rating Scale. Results: Results showed that the children who received local anesthesia using the device method had a lower mean pulse rate, FLACC scores, and pain rating scores than those who received local anesthesia using the conventional method. Conclusion: The device method was more effective than the conventional method in managing pain, anxiety, and behavior of patients aged 6-11 years. The device is a cost effective, simple, and child-friendly product for administrating local anesthesia in pediatric patients.
