Purpose: The purpose of the study was to review functioning components of studies for measuring functional information using International Classification of Functioning, disability and health (ICF) in Korea. Methods: A literature review was conducted and eligible studies were identified via search of RISS, KISS, DBpia, KoreaMed, PubMed, and ISI databases published from 2001 to 2015. For inclusion in this review, a study should be published in a peer-review journal, must have participation of Korean researchers and/or developed in Korea, and should provide functioning data related ICF. Descriptive studies containing only ICF concepts and review studies were also excluded. Collected functioning data in each study were analyzed using frequency based on ICF domain. Data assessment was performed by two independent reviewers. Results: Eighty publications were included in the analysis. The majority of studies collected data from clinical patients (n=38) and from the disabled (n=28). Fourteen studies assessed functioning data from the elderly and students under special education. The studies reported functioning data using various tools, including ICF itself, ICF checklist, coresets, and conventional measurement tools. Body function domain was most commonly used and the least used domain was the body structure across areas. Interestingly, increasing data related to environmental factors was observed in all studied populations. Conclusion: Functioning data was collected from four domains of ICF across professional areas. The most common collected data was body function and activity and participation for which conventional measurement tools are already available. To understand clients, components of environmental factors that might influence a person's functioning should be considered.

Objectives The purpose of this study was to examine the characteristics of diagnostic pattern questionnaire associated with Body Mass Index in premenopausal women. Methods We studied 41 patients visiting Gangdong Kyung Hee University Hospital from 1st April 2011 to 25th May 2011. The subjects were categorized in two groups, overweight & obesity group (n=12) and low weight & normal group (n=29). We studied the difference of diagnostic pattern questionnaire scores between two groups by Independent samples T-test and correlation between diagnostic pattern questionnaire scores of overweight & obesity group by Pearson's correlation coefficient test using SPSS for windows (version 13.0). Results Blood stasis, retention of undigested food, cold pattern scores of overweight & obesity group were non-significantly higher than low weight & normal group. Heat pattern score of overweight & obesity group was significantly higher than low weight & normal group. Cold-heat, phlegm-cold, blood stasis-cold, phlegm-blood stasis, phlegm-retention of undigested food significantly showed positive correlation coefficient in overweight & obesity group. Conclusions The results suggest that obese women tend to show heat pattern. It seems to be that multiple factors such as phlegm, blood stasis, retention of undigested food are causative of obesity.

The ergonomic human model can be considered as a tool for the evaluation of ergonomic factors in vehicle design process. The proper anthropometric data on driver's postures are needed in order to apply a human model to vehicle design. Although studies on driver's posture have been carried out for the last few decades, there are still some problems for the posture data to be applied directly to the human model due to the lack of fitness because such studies were not carried out under the conditions for the human model application. In the traditional researches, the joint angles were evaluated by the categorized data, which are not appropriate for the human model application because it is so extensive that it can not explain the posture evaluation data in detail. And the human models require whole-body posture evaluation data rather than joint evaluation data. In this study a postural evaluation function was developed not by category data but by the concept of the loss function in quality engineering. The loss was defined as the discomfort in driver's posture and measured by the magnitude estimation technique in the experiment using a seating buck. Four loss functions for the each joint - knee, hip, shoulder, and elbow were developed and a whole-body postural evaluation function was constructed by the regression analysis using these loss functions as independent factors. The developed postural evaluation function shows a good prediction power for the driver's posture discomfort in validation test. It is expected that the driver's postural evaluation function based on the loss function can be used in the human model application to the vehicle design process.

This study was conducted to obtain the acute information of the oral dose toxicity of lyophilized water extract of Picrorrhiza Rhizoma (PR) - dried underground stem of Picrorrhiza kurroa, having various pharmacological effects, in male and female mice. In order to calculate 50% lethal dose ($LD_{50}$), approximate lethal dose and target organs, test article was administered once by oral gavage to male and female ICR mice at 2000, 1000, 500 and 250 mg/kg. The mortality and changes on body weight, clinical signs and gross observation were monitored during 14 days after dosing with organ weight and histopathology of 12 types of principle organs. As the results, we could not find any mortality, clinical signs, changes in the body weight and gross findings except for hair loss, a significantly (p<0.05) increase of body weight gains in 2000mg/kg of PR extracts-dosing male group and some sporadic gross findings. In addition, no meaningful changes on the organ weight and histopathology of 12 types of principle organs were detected in the present study except for significantly (p<0.05) but dose independent changes on thymus, spleen and popliteal lymph nodes weights, and some sporadic accidental histopathological findings. The results obtained in this study suggest that the PR extract is non-toxic in mice and is therefore likely to be safe for clinical use. The $LD_{50}$ and approximate lethal dose of PR extracts in both female and male mice were considered as over 2000 mg/kg.

It is expected that the typical lifestyle of the future will be transformed into an opulent and comfortable existence as the quality of life improves due to the increase in household income and reduction in working hours. In the meantime, as the standard of living becomes increasingly more comfortable and plentiful, the toll on physical health becomes magnified as a result of obesity and insufficient exercise caused by super nutrition and change in labor conditions. This has instigated a deep awareness in fitness on the part of many people, forcing them to recognize the significance of daily exercise and physical activity. The Elliptical Cross Trainer(ECT), which has drawn wide attention recently, is a non-impact athletic apparatus that not only promotes exercise of the upper body parts in such sports as skiing but also the exercise of lower parts of the body on a treadmill. It is a type of cross training athletic gear that has been developed for aerobic exercise throughout the entire body. It has already formed a market as big as that of the treadmill in Europe, America, etc. Recently, its demand is growing sharply in the Korean markets as well as those in Northeast Asian countries. Despite such demand increase and expansion, since most of the expensive ECTs are exclusively supplied by suppliers in only a few advanced countries, localization of the ECT is urgently required in order to enhance competitiveness of Korean manufacturers and to expand the market. The ECT development project has been in full swing for approximately two year since 2004 in order to secure independent design, as well as engineering and manufacturing processes in efforts to develop a commercially viable ECT.

3체 문제에 있어서 Newtonian 운동방정식의 특이접은 수치적분에 의한 특수해를 구하는 과정에서 정확도를 떨어뜨리고 computer 사용시간을 증가시킨다. 이러한 특이점은 Newtonian 운동방정식의 독립변수와 좌표축을 변환하는 정칙화(regularization)과정을 통해 제거할 수 있다.이 논문에서는 정칙화된 Newtonian 운동방정식을 $5^{th}$ -order Runge-Kutta 방법으로 특수해를 구하기 위해 BASIC 언어로 작성한 computer program 으로 적절한 초기위치와 초기속도를 가정하여 시간에 따른 3체의 위치와 속도를 계산하였다. 그 결과, 이러한 3중성계의 진화는 결국 분열되어 3체 중 1개는 쌍곡선 궤도를 그리면서 계를 탈출하고 나머지 2개는 연성계를 형성하게 되었다. 이는 연성계의 기원을 설명할 수 있는 하나의 방버이 되지 않을까 생각한다.

Purpose: The most feared complication of gastrointestinal tract operations is anastomotic leakage, not only because of the presumed individual surgeon's culpability but also because of the assumption that this event is often fatal. We have experienced 32 cases of anastomotic leakage after elective gastric resection during 8 years. The purpose of this study was to evaluate the result of their treatment. Materials and Methods: We evaluated the records of 1335 patients who had undergone elective gastric resection for an adenocarcinoma of stomach from January 1995 to October 2003 and conducted a retrospective, multivariate analysis. Results: Of the 1335 patients, 32 ($2.4\%$) sustained an anastomotic leakage. Anastomotic leakages usually developed on mean postoperative day $9.1\pm3.2$ (range:$1\∼18$ days).Overall, $31.3\%$ (10/32) of patients who sustained an anastomotic leakage died. The anastomotic leakages were identifed by radiological study or by operative finding at the site of the duodenal stump (20 patients), the esophagojejunostomy (7), the gastroduodenostomy (4), and the gastrojejunostomy (1). Fourteen patients ($43.8\%$) underwent a relaparotomy, a drainage procedure in the main, and 18 patients ($56.3\%$) were treated conservatively. The mortality rates were $42.9\%$ (6/14) and $22.2\%$ (4/18), respectively, but this difference was not statistically significant. A cox's proportional hazard analysis showed that a body-mass Index < 24 kg/m2 (odds ratio 5.55, $95\%$ CI: $0.69\∼44.82$) and non-enteral feeding (odds ratio 18.27, $95\%$ CI 2.22.150.69) were independent factors of mortality due to anastomotic leakage. Conclusion: Our observations show that anastomotic leakage after an elective gastric resection has a high risk of being fatal. Moreover, for a patient with a body-mass index lower than $24\;kg/m^{2}$ and/or non-enteral feeding, an anastomotic leakage after an elective gastric resection has a higher risk of being fatal.

The object of this study was to obtain acute toxicity information (single-dose oral toxicity) of Woohwangchungshim-won (WHCSW), a pill type herbal medicine used in Korean Medicine (KM) for treating stroke. In order to obtain the 50% lethal dose (LD50), approximate lethal dosage (ALD) and target organs, WHCSW powders were once orally administered to female and male ICR mice at dose levels of 2,000, 1,000, 500 and 0 (control) mg/kg (body weight.) according to the recommendation of Korea Food and Drug Administration (KFDA) Guidelines (Notification No. 2009-116). The mortality and changes in the body weight, clinical signs and gross observation were monitored for 14 days after single-dose oral administration of WHCSW according to KFDA Guidelines with organ weights and histopathological changes were observed in 12 principle organs. After single-dose oral administration of WHCSW, we could not find any mortality and toxicological evidences up to 2,000 mg/kg-administered group, except for some accidental findings and dose-independent increases of body weight gains in female 1,000 and 500 mg/kg-administered female mice. The results obtained in this study suggest that the LD50 and ALD of WHCSW in both female and male mice after single-dose oral administration were considered as over 2,000 mg/kg because no mortalities were detected up to 2,000 mg/kg that was the highest dose recommended by KFDA and Organization for Economic Co-Operation and Development (OECD), and can be safely used in clinics.

Many medicinal plants have been used for the treatment of edema, jaundice, and gonorrhea in traditional Oriental medicine. This screening study was designed to search the positive inotropic effects of herbal extracts in beating rabbit atria. Aquarius extracts of twenty six herbs were examined in atrial mechanical dynamics such as pulse pressure and stroke volume and atrial natriuretic peptide (ANP), one of the main hormones involved in the regulation of the body fluid and blood pressure homeostasis in perfused beating rabbit atria. Sophora flavescens Ait., Rheum officinale Baill., Acorus gramineus Sol., Chelidonium majus L., Pulsatilla koreana Nakai., Reynoutria japonica Houtt., Euphorbia lathyris L., Pyrrosia lingua (Thunb.) Farwell, Poncirus trifoliata Rafin., Anemarrhena asphodeloides Bunge, Kochia scoparia Schrad. significantly increased stroke volume and pulse pressure. However, those herbal extracts were not induced ANP secretion. We clarified the eleven herbal extracts for the positive inotropic effect independent of ANP secretion in beating rabbit atria. Thus these results provide a beneficial data for the treatment of the impairment of body fluid and blood pressure in traditional Oriental medicine.
