An underwater glider makes it easy to explore a wide area with low power. However, an underwater glider is difficult to use for rapid collection, because the surfacing location cannot be predicted after a dive. Thus, simulation research is needed to predict the swimming path. In this paper, based on research, a linearized equation is derived for the drag coefficient at each angle of attack by assuming the boundary conditions for the Slocum underwater glider and performing a computational flow analysis.

8개월령의 체중이 40.4kg인 로트와일러 수컷 어린개와 9개월령의 체중 34.6kg인 골 든 레트리버 수컷 어린개가 각각 2주령과 1개월령부터 파행 및 통증을 주중으로 머독대학 동물 병원에 내원 하였다. 내원 했을 때 호흡과 심박수 및 체온은 정상이었다. 일반 보행 및 신경검사 와 방사선 사진을 촬영하여 확인한 결과 양측 고관절 이형성(Hip displasia)과 퇴행성 관절질환 (Degenerative joint disease)을 확인 할 수 있었으며, 그 증상의 정도는 우측에 비하여 좌측이 더 심하게 나타냈다. 외과적 치료는 Slocum과 Devine에 의한 3중 고관절 절단술(Triple pelvic osteotomy)를 실시하였으며 특별한 외부 고정은 하지 않았다. 수술 후 5개월 동안 지켜본 결과 증 상은 매우 좋아졌으며 골반골의 완벽한 고정 유지에 따른 교정된 고관절을 확인 할 수 있었다.

The underwater glider is an autonomous vehicle that can glide through the ocean interior by using a pair of wings attached to its body and can move up and down through the water column by changing its buoyancy. As of now, there are three widely-used gliders, namely, the Spray that was co-developed by Scripps Oceanographic Institution and Woods Hole Oceanographic Institution, the Slocum produced by the Webb Research Cooperation, and the Seaglider that was produced by the University of Washington. In this paper, I will introduce these three gliders and discuss the principles and procedures related to glider operation as well as the application and extendability of modern physical and bio-geochemical sensors to gliders. My experiences in developing a glider for measuring ocean turbulence and testing it 7 times during 12 days are shared in this paper. On the basis of my experiences and knowledge, different kinds of aspects that should be considered for successful glider operation are discussed. In addition, a suggestion is made as to what would be the ideal way to operate underwater gliders in the East/Japan Sea. At the end, the current status of active glider operation teams is presented and the efforts to proceed toward future gliders are briefly introduced.

The purpose of this article is to examine maritime accident and corporate criminal liability in comparison with cases and laws in UK and US. In Anglo-American law, a corporation can be convicted of and sentenced for a criminal offence. However, some theoretical difficulties lie in fixing a corporation with the appropriate mens rea. The Corporate Manslaughter and Corporate Homicide Act 2007 in England is to solve those difficulties and punish a corporation like a natural person. Comparing to Anglo-American law, a corporation is difficult to be punished in Korean law because it is a well recognized theory that only natural person is capable of committing a crime. However, safety in society and workplace is earning great concern in Korea, and emphasis is put on responsibilities of corporations. This article discusses the need for legislation on corporate manslaughter act in Korea with regard to the sinking of the MV Sewol.

Background: Total elbow arthroplasty (TEA) is uncommon, but growing in incidence. Traditionally an inpatient operation, a growing number are performed outpatient, consistent with general trends in orthopedic surgery. The aim of this study was to compare TEA outcomes between inpatient and outpatient surgical settings. Secondarily, we sought to identify patient characteristics that predict the operative setting. Methods: Patient data were collected from the American College of Surgeons National Quality Improvement Program. Preoperative variables, including patient demographics and comorbidities, were recorded, and baseline differences were assessed via multivariate regression to predict operative setting. Multivariate regression was also used to compare postoperative complications within 30 days. Results: A total of 468 patients, 303 inpatient and 165 outpatient procedures, were identified for inclusion. Hypoalbuminemia (odds ratio [OR], 2.5; P=0.029), history of chronic obstructive pulmonary disorder or pneumonia (OR, 2.4; P=0.029), and diabetes mellitus (OR, 2.5; P=0.001) were significantly associated with inpatient TEA, as were greater odds of any complication (OR, 4.1; P<0.001) or adverse discharge (OR, 4.5; P<0.001) and decreased odds of reoperation (OR, 0.4; P=0.037). Conclusions: Patients undergoing inpatient TEA are generally more comorbid, and inpatient surgery is associated with greater odds of complications and adverse discharge. However, we found higher rates of reoperation in outpatient TEA. Our findings suggest outpatient TEA is safe, although patients with a higher comorbidity burden may require inpatient surgery. Level of evidence: III.

In the U.S., outdoor enthusiasts such as golfers have been focused on skin cancer prevention practices since their outdoor activities lead to extensive sun exposure during peak sun hours. The purposes of this study were to investigate golfers current sun protection behaviors and five attributes and their impacts on the intention to adopt UV specialized clothing based on Rogers' theory. UV specialized clothing as a preventive innovation is related to sun protection behaviors. However, there has been little effort to explain the intention to adopt a preventive innovation regarding health-related practices. With a convenience sampling method, a total of 158 useful questionnaires were collected. Ninety one percent were male golfers, and their age ranged from 16 to 80 years old(mean age=30 years). About $25\%$ reported to practice sun protection behaviors. About $70\%$ disagreed on the relative advantage, compatibility, observability, and triability of UV specialized shirts and reported the low intention to purchase it. Current sun protection behaviors and five attribute variables were entered in the multiple regression equation to explain the dependent variable of intention to adopt the innovation. Triability was the best predictor of the intention to adopt UV specialized shirts, followed by current sun protection behaviors, compatibility, and relative advantage. With four predictors, $45\%$ of the variance of intention to adopt was explained. The present study provides how the golfers current sun protection behaviors play important roles in explaining the intention to adopt the preventive innovation. Physical and functional features of UV specialized clothing were also significantly associated with their intentions to adopt it.
