Background: Arthroscopic shoulder surgery can result in severe postoperative pain. A variety of methods have been used to control pain in postoperative period and the results are variable. The purpose of this study was to compare the relative analgesic efficacies of the postoperative intraarticular infusion of ropivacaine, ropivacaine/fentanyl, and ropivacaine/fentanyl/ketorolac after arthroscopic shoulder surgery. Methods: Thirty patients undergoing arthroscopic shoulder surgery under general anesthesia were randomly assigned to three groups. At the end of surgery, 0.5% ropivacaine 20 ml was infused into the articular space and a continuous infusion catheter was inserted into intraarticular operated site. After surgery, continuous infusion of 0.5% ropivacaine 100 ml (Group 1, n=10), 0.5% ropivacaine 100 ml including fentanyl 10 μg/kg (Group 2, n=10), or 0.5% ropivacaine 100 ml including fentanyl 10 μg/kg and ketorolac 150 mg (Group 3, n=10) was started through catheter at rate of 2 ml/hr with bolus dose of 0.5 ml with a lock out time of 15 minutes for 2 days. The level of pain was assessed using a visual analogue scale (VAS) postoperative 2, 6, 12, 24 and 48 hours and the amounts of supplemental analgesics were recorded. Results: The VAS was significantly lower after 2, 6, 12 hours in Group 2 than in Group 1. In Group 3, the VAS was significantly lower all hours than in the other two groups. Conclusions: The combination of fentanyl and ketorolac with ropivacaine did provide better postoperative analgesia than the other groups after arthroscopic shoulder surgery.

The purpose of this study is to investigate the effects of perception of success on mental power. The analysis was based on 218 Taekwon-do players divided into high performance: 62 players and average: 156 players. Perceptions of Success Questionnaire(POSQ) and Korean mental power questionnaire were mainly used in this study. Findings: Male players and high performance group, using MANOVA, show higher level of task goal orientation, specifically winning spirit, struggling efforts, endurance variables are higher on males and high performance players. According to regression analysis the mental power variables are strongly explaining the task goal orientation. Particularly, endurance, struggling efforts are mainly significant variables explaining 76% variation of task goal orientation. Competitive goal orientation, too, is strongly explained by mental power variables which explains 59% of total variance. This study is based on previous studies and theoretical background.

In this study, we tested Japanese trolling lines in the Jeju fishery. This fishery simulates the natural marine environment with many seabed rocks, and has been redesigned and manufactured it to be suitable for the Jeju fishery. In order to ensure that the trolling lines were deployed at the inhabitation depth of hairtails, the conditions required for the fishing gear to reach the target depth were determined for use during the experiment. The experimental test fishing was conducted at the depth of 120 m water in front of Jeju Seongsanpo and in the offshore area of Jeju Hanlim. The fishing gear used in the test fishing is currently used in a variety of field operations in Japan. However, several problems were identified, such as twisting of the line during its deployment and excessive sinking of the main line. The fishing gear was, therefore, redesigned and manufactured to be more suitable for the Jeju fishery environment. For the fishing gear to accurately reach the target depth, depth loggers were installed at the starting point of the main line and at the 250 m and 340 m points of the line. Depth and time were recorded every 10 seconds. According to the daytime positioning of hairtails in the lower water column, the target depth of the fishing gear was set at 100-110 m, which was 10-20 m above the sea floor. At a speed of 1.9 knots and with a 9 kg sinker attached, the main fishing line was deployed and catch yields at depths of 100 m, 150 m and 180 m were recorded and analyzed. When the 180 m main line was fully deployed, the time for the hairtail trolling lines to arrive at the appropriate configuration had to be 5 minutes. At this time, the depth of the fishing gear was 16-23 m above the sea floor, in accordance with the depths at which the hairtails were during the day. In addition, in order to accurately place the fishing gear at the inhabitation water depth of hairtails, the experimental test fishing utilized the results of the depth testing that identified the conditions required for the fishing gear to reach the target depth, and the result was a catch of up to 97 kg a day.

In this study, an seismic isolation system is suggested using a Natural Rubber Bearing(NRB) on a stainless steel water tank for stability assurance in an earthquake. A shaking table test was carried out to evaluate the seismic capacity of a non-isolated water tank and an isolated water tank. Displacement meters in the water tank measured the behavior characteristics of the tanks, which were compared using artificial seismic waves of 0.154g, 0.231g, 0.341g and 0.348g with water levels of 0.0m, 1.5m and 2.5m. At 2.5m, a decrement effect was generally shown in the isolated water tank, and a bigger displacement occurred in the non-isolated water tank than in the isolated one at water levels of 0.0m and 1.5m. It is interpreted that the weight of different water levels affects the decrement effect. If seismic reinforcement is done, the isolated bearing should be designed while considering the fluid storage level.

글로벌 경쟁이 가속화되면서 첨단기술을 적용한 제품 개발을 위해 각 기업에서는 지속적인 기술혁신을 추진하고 있다. 특히 최근의 IT기술의 비약적 발전과 더불어 이를 적용한 융·복합 신기술의 등장으로 그 경쟁은 더욱 치열해지고 있다. 이러한 기술혁신은 제품의 품질과 신뢰성은 높이면서도 개발 비용 및 시간을 최소화하여 시장진입시간(time to market)을 줄이는 것이 핵심이다. 이를 위해서는 물리적 실험을 통한 시행착오(trial and error)를 반복하는 제품 개발 방법보다는 고성능 컴퓨터를 활용하여 시뮬레이션을 수행하는 것이 필요하다. 일반적으로 국내 산업체는 대기업, 중견기업, 중소기업으로 분류되는데, 이들의 인적·물적 규모에 따라 연구개발에 대한 투자가 규모나 방법론에서 매우 큰 차이를 보인다. 따라서 이들의 기업 특성에 적합한 고성능 컴퓨터 활용 시뮬레이션 지원전략을 수립하여 접근하는 것이 중요하다. 본 논문에서는 기업의 기술수준에 따른 차별화된 시뮬레이션 지원전략을 제시하여 투자대비 효과를 극대화하고, 이를 통해 국내 산업 전반의 발전을 도모할 수 있는 방안을 모색한다.

The aim of this study is to examine the relationship between sports goal orientation and coping strategy. The total sample size was on 918 (male;589, female;329) athletes including Korean national team members, junior-high school, high school, college and professional athletes. Perceptions Of Success Questionnaire and the Athletic Coping Skills Inventory were mainly used to collect the data. The results are the following. First, the difference between sports goal orientation and coping skills strategy did not show significant variation, especially in sports goal orientation. Coping skills, peaking under pressure, concentration, goal setting and mental preparation, however showed a higher level based on different age groups. Also, top performers revealed to show higher level of peaking under pressure, goal setting and mental preparation. Regression analysis was used to investigate the relationship between coping strategy and sport task orientation. The results varied according to different age groups. To junior-high school athletes, freedom from worries and peaking under pressure showed significant impact. Goal setting and mental preparation and peaking under pressure variables showed significant effects on high school athletes. Coachability and goal setting and mental preparation variables were explaining task goal orientation to college and professional athletes. Regression analysis were used on different age groups to find the relationship between coping strategy and competition goal orientation. According to the results, goal setting and mental preparation, freedom from worry, peaking under pressure showed significant effects on junior high athletes. Goal setting and mental preparation showed significant effects on high school athletes. Concentration variables explained competition goal orientation on college and professional athletes. Setting goals and mental preparation explained the task goal orientation of top performer athletes. Moreover, setting goal and mental preparation with coachability, concentration, freedom from worry explained task goal orientation of average athletes. Finally, according to the discriminant analysis setting goals and mental preparation were significant variables among coping strategy to distinguish between top and average performer athletes. And peaking under pressure variable was significant to junior-high, high school, college and professional athletes. These results were conducted based on previous studies and further analysis are needed to improve and illuminate theoretical discussion.
