Purpose: Recently, many studies on robotic rehabilitation have been conducted, but such studies on patients with ankle sprains are lacking. This study aimed to investigate the effects of robot-assisted rehabilitation on the range of motion of the ankle and balance in patients with ankle sprain. METHODS: This study used the A-B-A' design and was conducted for a total of fifteen days. The subjects performed general physical therapy for five days each, during the baseline A and A' periods. In period B, robot rehabilitation was performed for five days, along with general physical therapy. The subjects were evaluated based on weight-bearing lunge test (WBLT), single leg stance (SLS), and functional reach test (FRT). RESULTS: The WBLT, STS, and FRT showed significant improvement in periods B and A' compared to period A, but there was no significant improvement in period A' compared to period B. Conclusion: This study confirmed that robot-assisted rehabilitation was an effective intervention for improving the function of patients with ankle sprain. In the future, a study with a control group comparison should be performed.

It was attempted in the present study to determind the effect of Korean ginseng on acute viral(B type) hepatitis by double blind test clinically and the results were as follows. 1. The double blind test of 4 week period showed no statistical significance of the effect of ginseng on the disease. 2. The double blind test of 2 week period, however, showed a significant effect in such clinical symptoms as appetite, stomach ache, headache, chillness dizziness, nausea and vomitting, stool habit change and jaundice. Improvement of the blood serum level of transaminases, bilirubin. alkaline phosphatase and cholesterol Chillness feeding period was observed.

Background : This study presented an analysis of healthcare quality indicators using data mining and a development of decision support system for quality improvement. Method : Specifically, important factors influencing the key quality indicators were identified using a decision tree method for data mining based on 8,405 patients who discharged from a medical center during the period between December 1, 2000 and January 31, 2001. In addition, a decision support system was developed to analyze and monitor trends of these quality indicators using a Visual Basic 6.0. Guidelines and tutorial for quality improvement activities were also included in the system. Result : Among 12 selected quality indicators, decision tree analysis was performed for 3 indicators ; unscheduled readmission due to the same or related condition, unscheduled return to intensive care unit, and inpatient mortality which have a volume bigger than 100 cases during the period. The optimum range of target group in healthcare quality indicators were identified from the gain chart. Important influencing factors for these 3 indicators were: diagnosis, attribute of the disease, and age of the patient in unscheduled returns to ICU group ; and length of stay, diagnosis, and belonging department in inpatient mortality group. Conclusion : We developed a decision support system through analysis of healthcare quality indicators and data mining technique which can be effectively implemented for utilization review and quality management in a healthcare organization. In the future, further number of quality indicators should be developed to effectively support a hospital-wide Continuous Quality Improvement activity. Through these endevours, a decision support system can be developed and the newly developed decision support system should be well integrated with the hospital Order Communication System to support concurrent review, utilization review, quality and risk management.

Purpose: First, this paper suggests an alternative approach to find optimal portfolio (stocks, bonds and ESG stocks) under the maximizing utility of investors. Second, we include ESG stocks in our optimal portfolio, and compare improvement of welfares in the case with and without ESG stocks in portfolio. Methods: Our main method of analysis follows Brennan et al(2002), designed under the continuous time framework. We assume that the dynamics of stock price follow the Geometric Brownian Motion (GBM) while the short rate have the Vasicek model. For the utility function of investors, we use the Power Utility Function, which commonly used in financial studies. The optimal portfolio and welfares are derived in the partial equilibrium. The parameters are estimated by using Kalman filter and ordinary least square method. Results: During the overall analysis period, the portfolio including ESG, did not show clear welfare improvement. In 2017, it has slightly exceeded this benchmark 1, showing the possibility of improvement, but the ESG stocks we selected have not strongly shown statistically significant welfare improvement results. This paper showed that the factors affecting optimal asset allocation and welfare improvement were different each other. We also found that the proportion of optimal asset allocation was affected by factors such as asset return, volatility, and inverse correlation between stocks and bonds, similar to traditional financial theory. Conclusion: The portfolio with ESG investment did not show significant results in welfare improvement is due to that 1) the KRX ESG Leaders 150 selected in our study is an index based on ESG integrated scores, which are designed to affect stability rather than profitability. And 2) Korea has a short history of ESG investment. During the limited analysis period, the performance of stock-related assets was inferior to bond assets at the time of the interest rate drop.

This study examines the details and characteristics of prizewinning plans of Cho-Sun housing plan competition promoted by Daily Cho-Sun Company during Japanese colonial period. The main features of Cho-Sun housing plan competition were that the competition held with an application of popular newspaper readers and a judging committee was composed of only Korean architects, especially Park, Gil-Ryong as the president of the board of examiners. Cho-Sun housing plan competition put ideological factors for the improvement of living as like advancing to the cultured(modem) life, respecting for family life, respecting for privacy of family members and so on. First of all, the competition suggested the direction of the improvement of dwelling spaces which focused on making harmonious home life. This study found common characteristics of prizewinning plans of Cho-Sun housing plan competition as the result. First, Cho-Sun housing plan competition introduced a centralized house plan as a model of the improvement of small-sized houses. Second, architectural orders of western or Japanese style mingled with ones of korean traditional style in prizewinning plans as entrance hall, western style reception room(parlour), maid's room, bathroom for example. And a manner of seating using chairs was brought into the style of living which would be assumed in the prizewinning plans. Third, traditional way of composing dwelling spaces was maintained, receiving the characteristics of dwelling spaces of japanese style simultaneously, which central corridor was put at the heart of house for improving arrangement of rooms and flow lines. Fourth, lavatory and bathroom were placed inside of the house.
