Arthritis may be broadly classified as degenerative - related to defects in cartilage and other joint constituents, often age-associated - or inflammatory disease. Inflammatory arthritis called as rheumatoid arthritis (RA) is a chronic inflammatory arthropathy and characterized by a destructive arthritis. RA encompasses infectious arthritis, arthritis caused by intra-articular deposits of crystalline material (gout), syndromes associated with genetic defects (familial Mediterranean fever), and the immune-mediated inflammatory arthropathy. Degenerative arthritis called as osteoarthritis (OA), which is most frequently occurring, causes degenerative figures of knee, waist and knuckle, and accompanies severe pain around the cartilage. Also, it may cause morning stiffness, gelling effect, tenderness, bone swelling, crepitus, and motion disorders.

We report here on a case of Achilles tendon rupture associated with ipsilateral bimalleolar fracture that was caused by ski injury. The association of an ankle fracture with rupture of the Achilles tendon is even more infrequent, although both injuries alone are extremely common. We treated as a operation of Achilles tendon repair with Krackow method and open reduction with Tension-band wiring technique for bimalleolar fracture.

Life Science Research Center of SK Chemicals has developed a 3rd-generation anticancer platinum drug for the first time in the nation′s 100-year-old pharmaceutical industry. The Korea Food and Drug Administration (KFDA) approved the sale of "Sunpla" (code name SKI 2053R, general name : Heptaplatin) on July 14, 1999 for the treatment of advance, metastatic gastric cancer. Cisplatin, the 1 st-generation anticancer drug, which was developed by Bristol-Myers of the United States in 1976, is one of the most potent anticancer drugs and is a major component of combination chemotherapy for a variety of human cancers. However its clinical usefulness has frequently been limited not only by undesirable side effects such as severe renal toxicity, nausea, vomiting, ototoxicity, and neurotoxicity but also by the development of resistance. Carboplatin, the 2nd-generation anticancer platinum drug, which was also developed by Bristol-Myers in 1986, has modified the problems of the renal and gastrointestinal toxicities of cisplatin. Carboplatin, however, has no enhanced therapeutic efficacy over cisplatin and does not possess the property to overcome cross-resistance to cisplatin.

본 논문에서는 의료영상 영역화 기법으로 이용되는 레이블 융합 기법을 기반으로, 정합 기법을 이용했을 시 빈번하게 발생하는 경계에서의 오차를 크게 줄여줄 수 있는 기법을 제안한다. 패치 기반 레이블 융합 기법은 패치 간의 밝기 값의 유사도를 기반으로 융합 가중치를 계산하였지만 이는 밝기의 분포가 상대적으로 다른 자기공명영상에 적합하지 못한 경우가 많았다. 본 논문에서는 밝기 값과 함께 밝기 값의 경사도 유사도를 추가적으로 계산하여 융합 가중치를 얻어내는 기법을 제안한다. 밝기의 분포가 다른 영역에서도 밝기의 경사도 분포는 대부분 유사하기 때문에, 오차가 많은 모호한 경계에서 향상된 결과를 얻을 수 있었다. 제안하는 기법의 성능평가를 위해 50 개의 SKI10 무릎 관절 데이터 셋 내에서 대퇴골을 영역화 하였다. 실험 결과를 통해 제안하는 기법이 밝기 값 유사도 정보만을 이용했던 기법에 비해 개선된 성능을 보이고 있음을 확인할 수 있다.

1990년대 이후 스키 인구는 성장추세를 보여 왔으나, 현재 포화상태에 도달했다고 판단된다. 본 연구에서는 스키 참가자의 레크리에이션 전문화 수준 향상이 위기에 봉착한 스키산업의 돌파구로서 작용할 수 있다고 판단하고, 레크리에이션 전문화에 부정적인 영향을 미친다고 보고된 여가제약 요인을 실증적으로 제시하고 스키 참가자의 레크리에이션 전문화 수준별 여가제약 요인의 특징을 규명했다. 스키 참가자의 여가제약은 동반자, 개인적, 경제, 타인의식, 여건, 시설의 6개 요인으로 나타났다. 레크리에이션 전문화 수준별 여가제약 요인의 평균을 비교해본 결과 레크리에이션 전문화 수준이 낮은 집단에서는 경제적 요인, 레크리에이션 전문화 수준이 중간인 집단과 높은 집단에서는 시설요인이 가장 높은 수준으로 나타났다. 여가제약 요인별 레크리에이션 전문화 수준에 따른 여가제약 수준의 차이를 분석해본 결과 모든 요인에서 유의미한 차이가 나타났다.

This study proposes a sports simulation device with various harmonics generation. The proposed system is composed of 6 degrees of freedom simulator devices and three types of sports simulation such as walking, snowboard, and jet-ski. In this research, every joint movement is designed with a crank-and-slider mechanism, which is efficient for generating continuous curvature smoothly. Contrary to the conventional spatial simulator with linear actuators, harmonics generation and its spatial combinations become the crucial issue in this research. The harmonic pattern in each joint is modelled for generating smooth curvatures that are also superposed for achieving overall motions. In addition, the targeted motions of sports simulations have different physical factors of periodic gait motion, frictionless surface, and buoyant effects, which are respectively designed by integrating three dimensional graphics information.

In this paper, the numerical results concerning different orbits of a 3D axisymmetric non-rotating galactic potential are presented. We use $Paczy{\acute{n}}ski^{\prime}s$ gravitational potential with different birth velocity distributions for the isolated old Neutron Star (NS) population. We note some smooth non-constant segments corresponding to regular orbits as well as the characterization of their chaoticity. This is strongly related to the effect of different kick velocities due to supernovae mass-loss and natal kicks to the newly-formed NS. We further confirm that the dynamical motion of the isolated old NSs in the gravitational field becomes obvious, with some significant diffraction in the symmetry of their orbital characteristics.

This study aims to provide preliminary data capable of suggesting directivity of an initiating start by understanding consumer awareness through analysis of SNS social big data on marine sports. This study selected windsurfing, yacht, jet ski, scuba diving and sea fishing as research subjects, and produced following results by setting period of total 1 month from January 22 through February 22, 2017 on the SNS (twitter, blog) through the Social MatrixTM service of Daumsoft Co., Ltd., and analyzing frequency of mention, associated words etc. First, sports that was mentioned the most out of marine sports was yacht, which was 3,273 cases on twitter and 2,199 on blog respectively. Second, the word which was shown the most associated with marine sports was the attribute showing unique characteristic of marine sports, which was 6,261 cases in total.
