The purpose of this study is to present the research data to improve the quality of triangular ward in general hospital in Korea. Drawing documents analysis were used to examine the condition of ward. This study in focused on patient room and atrium according to connection type of triangular ward, allocation of NS, module and direction of patient room. The results of this study is as follows; Triangular ward has two joint pattern(conner and conner, side and side). Conner and conner joint pattern is good at planning of lighting than side and side joint pattern. Triangular ward can has different module system in each side. Allocation of NS is important factor which is focused on patient relationship or ward control.

In recent years, hydroforming technology has been one of the most important technology in automotive industry in the points of weight saving, cost reduction and qualify improvement. However, compared with traditional metal forming technology, hydroforming has much fewer information in experience and empirical knowledge. But we don't have my sufficient time and money to produce hydroforming products using real blank directly Therefore Simulation is essential in hydrofonrung technology development. In this paper, we simulate the side member as the tubular hydroforming technology. The manufacturing process of side member' consists of pre_bending, pre_forming, and hydroforming of a thin tube. Variables such as internal pressure, end feeding, and tool geometry are optimized to improve the forming safety. And we simulate side member according to several lubricant conditions. from those simulations, we find that strain distributions can be reduced well by internal pressure and end feeding control, and lubrication is the most important thing in hydroforming process.

Situs inversus abdominis is a rare congenital condition commonly associated with serious cardiac and splenic malformations. The importance of recognizing the presence of situs inversus abdominis preoperatively is emphasized by the fact that the surgical incision is placed on the incorrect side of the abdomen. A 6 day-old girl was referred to our hospital because of bile stained vomiting. A plain radiography of abdomen and chest showed the heart to be normal position and a reversed "double-bubble" picture with no other gas shadow in the rest of the abdomen. Abdominal computed tomography scan revealed situs inversus with the stomach and polysplenia on the right side and the liver on the left side. A laparotomy confirmed the diagnosis of situs inversus with duodenal atresia. The obstruction was bypassed by constructing a side-to-side duodenoduodenostomy. The postoperative course was uneventful.

The purpose of this study was to find the most effective movement pattern from three different types of preparatory movement(squat, countermovement and hopping) in sideward responsive propulsion task, which had the time constraint to complete the performance. 7 healthy subjects participated in left and right side movement task by an external signal, which required the subject to perform the task as fast as possible. Mechanical output and joint kinetics focusing on the lower extremities were analyzed. The results were as follows. In spite of the shortest duration in propulsive phase, the hopping condition showed no difference with other conditions in the work output done and take-off velocity. It resulted from the greatest power output generated during the propulsive phase. A significant difference was found for joint moment and joint power according to the movement conditions. The joint moment and joint power for the countermovement and hopping conditions were larger than those in the squat condition. This was speculated to be due to the extra power that could be generated by the pre-stretch of muscle in preparation for the propulsion. The hopping condition which had substantially more pre-stretch load in the preparatory eccentric phase produced considerably more power than countermovement condition in the propulsive concentric phase. Furthermore during the hopping a large amount of joint moment and joint power could be produced in a shorter time. Therefore it was deemed that the hopping movement is an effective type of preparatory movement which takes much more advantage of the pre-stretch than any other movement.

This research investigates vehicle structure acceleration and vehicle deformation with RCAR crash test. To investigate vehicle damage characteristics in an individual case, it is possible to RCAR low speed crash test. In this study, two tests were conducted to evaluate difference between RCAR new condition and RCAR old condition. A two large vehicles were subjected to a frontal crash test at a speed of 15km/h with an offset of 40% $10^{\circ}$ angle barrier and flat barrier. The results of the 15km/h with an offset of 40% $10^{\circ}$ angle barrier revealed high acceleration value on the vehicle structure and high repair cost compared to the RCAR 15km/h with an offset of 40% flat barrier. So in order to improve damage characteristics in low speed crash of vehicle structure and body component of the monocoque type passenger vehicles, the end of front side member and front back beam should be designed with optimum level and to supply the end of front side member as a partial condition approx 300mm.

Objective : We evaluated the therapeutic effect of Banwhasasimtang dry extract powder on gastrointestinal symptoms and its side effects in patients with functional dyspepsia. Methods : Patients with functional dyspepsia, defined as discomfort in the epigastrium. A total 45 patients participated in this study. Dyspeptic symptoms ratio was obtained by patients, total point of symptom score/total 21 points x 100(%). On each of symptom after 4 weeks administration of Banwhasashim-tang was made by variation of symptom score: If symptoms score of posttreatment is lower than that of pretreatment, it is improved ; Otherwise aggravated, and if there is no change between them, unchangeable. When a full health condition of normal control is assumed 100%, relative health condition of dyspeptic patient could be calculated from 'full health condition-dyspeptic symptoms ratio'. Therefore a whole satisfaction rate on symptom improvement was presented with variation of a relative health condition to dyspepsia between pretreatment and post. Results : Banwhasashimtang significantly improved symptoms in patients. The significance was shown in both all seven items(p<0.01, respectively) and 19.2% (p<0.01) of increase of a whole satisfaction rate on symptom improvement. There is no remarkable side-effect in all laboratory test, excepting 1 case of abdominal pain and another one case of recurred pain of chronic prostatitis. Conclusion : Banwhasashimtang extract provides symptomatic relief in functional dyspepsia and is no remarkable side-effect drug.

This article develops a long-term condition assessment method for stay cables in cable stayed bridges using the monitored cable tension forces under operational condition. Based on the concept of influence surface, the matched cable tension ratio of two cables located at the same side (either in the upstream side or downstream side) is theoretically proven to be related to the condition of stay cables and independent of the positions of vehicles on the bridge. A sensor grouping scheme is designed to ensure that reliable damage detection result can be obtained even when sensor fault occurs in the neighbor of the damaged cable. Cable forces measured from an in-service cable-stayed bridge in China are used to demonstrate the accuracy and effectiveness of the proposed method. Damage detection results show that the proposed approach is sensitive to the rupture of wire damage in a specific cable and is robust to environmental effects, measurement noise, sensor fault and different traffic patterns. Using the damage sensitive feature in the proposed approach, the metrics such as accuracy, precision, recall and F1 score, which are used to evaluate the performance of damage detection, are 97.97%, 95.08%, 100% and 97.48%, respectively. These results indicate that the proposed approach can reliably detect the damage in stay cables. In addition, the proposed approach is efficient and promising with applications to the field monitoring of cables in cable-stayed bridges.

도로주변 절토사면 상부에 설치되는 산마루측구는 강우시 상부로부터 흘러내려오는 지표수를 원활히 배수시켜, 절토면으로 유입되는 것을 방지하기 위해 설치한다. 그러나, 산마루측구 설치시 시공여건상 품질관리가 어려워, 절토면 배면으로부터의 지표수를 원활히 배수시키지 못하는 문제점을 안고 있다. 따라서, 본 논문에서는 비탈면 상부에 설치된 산마루측구의 기능을 지반 및 지형조건, 강우조건에 따라 비탈면 안정성에 미치는 영향을 평가함으로써, 현재 설계 시공되고 있는 산마루측구의 설치 적정성을 평가하였다. 평가결과 산마루측구는 평균적으로 강우시 약 3%의 안전율 증대효과가 있는 것으로 검토되었다.

항정신병약물에 의한 부작용의 치료전략은 예방이 최우선이며, 그 다음이 조기발견 및 이에 대한 적절한 치료이다. 항정신병약물의 부작용을 강조하는 이유는, 약물에 대한 부정적 인상을 강화시키려는 데 있지 않고, 약물의 치료적 효과를 극대화시키려는 데 있다. 이를 위해서는 약물의 속성과 환자의 특징을 고려한 약물의 선택과 사용뿐만 아니라, 부작용에 대한 면밀한 이해와 이에 대한 치료전략을 숙지해야 한다.
