PURPOSE: The purpose of this study was to compare how the shoulder height and respiratory function are affected by applying shoulder stabilization exercises and core stabilization exercises that are effective for strengthening the trunk muscles and postural stability for adults with a round shoulder posture (RSP). METHODS: The participants were 28 young adults with RSP. They were assigned randomly to two groups: shoulder stabilization exercise and core stabilization exercise. They performed the exercises for 30 minutes twice a week for four weeks. They measured the shoulder height and respiratory function before and after exercise. RESULTS: No significant difference in shoulder height was found between the groups. A significant decrease in shoulder height was found in the shoulder stabilization exercise group after exercise. The core stabilization exercise group showed a significant decrease after exercise. In respiratory function, no significant difference was found between the groups. The forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁) were increased significantly in the shoulder stabilization exercise group before and after exercise. The FEV₁, FEV₁/FVC, and peak expiratory flow were significantly higher in the shoulder stabilization exercise group after exercise than in the core stabilization exercise group. CONCLUSION: Shoulder stabilization exercise and core stabilization exercise improved the postural alignment and pulmonary function, and the exercises could be helpful in shoulder rehabilitation as well as the clinical part of the treatment of rounded shoulder posture.

In an attempt to demonstrate the seasonal variation of the Ulleung Warm Eddy (UWE), in which the UWE changes its shape from a warm core ring in early spring to a warm lens in late summer under the effect of surrounding East Korean Warm Current (EKWC) Water, a simple geostrophic adjustment model is considered. Model results indicate that the buoyancy increase of the EKWC Water and the strengthening of the EKWC towards summer, both of which are typical of this region, are the major factors governing the seasonal variation of the UWE.

Korean mobile communications industry has been a main locomotive of the drastic development of Korean IT industry and became one of core industries in national economy. To secure strong competitiveness of mobile communications industry, smooth cooperation should be reconsidered among government, universities, research institutions, and private companies. Future mobile communications technology will be evolved from IMT-2000 to system upgrade, 3.5G and 4G. And the goals of technology development are provision of mobile multimedia services based on better mobility and higher data speed rates. Therefore, Korea's technology development strategies of mobile communications should be focused on intensifying bondage of international cooperation, strengthening standardization activities, and enhancing core technology development capability to secure IPR.

In knowledge information society entering global unlimited competition era, our middle and small sized companies are the base of national and enterprise competitiveness and core base of national economy as an origin of jobs. The competitiveness of middle and small sized companies is so important to decide the level of the competitiveness of the whole industries, but the gap from big sized company is much low in comparison with advanced countries from angles of important factors of enterprise growth, productivity and technological competitiveness, so, it's urgent to improve the competitiveness through productivity enhancement. The purpose of this research is to do a positive study on effects of learning organization management outcomes of middle and small sized company on enterprise productivity among various types of outcome brought for strengthening of enterprise competitiveness. It confirmed learning organization has functions and usefulness as a management tool bringing positive effects on enterprise productivity through the Productivity improvement.

Purpose: The purpose of this study is to review health-care program using the recent robotic horse-riding technology and its clinical effects for chronic low back pain. Research design, data and methodology: Recent clinical articles were determined under three inclusion criteria for in-depth review: 1) article that is published within 1 year, 2) article that includes the detailed explanation of health-care program using robotic horse-riding, 3) the article that deals with chronic low back pain during more than 6 months. Results: As a result, the finally-determined two articles demonstrated the clinical effects of robotic horse-riding statistically on pain intensity, low back muscle strength, spinal alignment, and fear-avoidance belief. Conclusions: After in-depth review, I concluded that health-care program using robotic horse-riding for chronic low back pain needs to be provided at low-intensity (e.g. less than 6km/h horse walking program) in the beginning of health-care for improving their motor control ability, then, at the increased intensity for strengthening core muscles.

Purpose: This study was conducted to investigate the effects of change in the unstable support surface location during bridge exercise on the muscle activity of erector spinae and gluteus maximus. Research design, data and methodology: 12 healthy participants aged 23.32 ±1.02 were measured muscle activities of erector spinae and gluteus maximus during bridge exercise and compared between the exercise conditions; unstable support surface located on upper back and feet during bridge exercise. Paired t-test was performed to identify whether there was a significant difference in the muscle activities between the exercise conditions. Results: As a result, even though higher levels of the averaged muscle activities of both erector spinae and gluteus maximus during exercise in unstable support surface located on feet than upper back were observed, no significant differences were found. Conclusions: The change of unstable support surface location during bridge exercise for low back pain rehabilitation would be more appropriate to be used to increase levels of tension of muscle activities and train fine motor control rather than to strengthening muscle strength.

세계 각국은 급변하는 시대의 발전 및 개혁 요구에 대응하기 위해 미래에 필요한 핵심역량을 기준으로 정보교과과정을 설계하고 시행하고 있다. 본 논문에서는 핵심역량을 비교 분석하여 초등 정보교육 핵심역량 프레임워크를 개발하였으며, 초등 정보교과 구성 방향성을 제시하였다. 각 국가 및 기관에서 제시한 역량 중 사회적-감정적 역량, 의사소통, 창의력, 책임감, 문화와 윤리, 문제 해결 능력, 협력, 추상 역량이 중첩되었으며, 국내 중·고등학교 정보 교과에서는 컴퓨팅 사고력과 정보기술 활용 능력을 중시함을 알 수 있었다. 이에 향후 초등 정보교과에서 제안된 핵심역량 프레임워크를 교과 구성에 반영하며, 사회적 책임감을 강화하고 융복합적 소양을 함양하여 문제해결력을 제고하는 방향으로 편성할 것을 제안하였다. 본 논문을 통하여 2022년 개정 교육과정에 핵심역량을 반영한 초등 정보교과 편성의 필요성이 확대되기를 바란다.

기업은 시작과 동시에 계속기업을 영위하면서 사회적 책임도 가지게 된다. 하지만 최근 기업의 평균수명이 점점 단축되고 있으며 기업환경 또한 급격하게 변화하고 있다. 따라서 본 연구에서는 글로벌 기업의 장수요인 분석을 통하여 기업의 장수, 즉 계속기업의 해답을 얻고자 하였다. 지멘스와 듀폰의 두 거대 글로벌기업의 장수요인을 분석해 본 결과 그 요인은 사업포트폴리오 변화, 위험관리, 지속적 연구개발, 신뢰경영, 친환경경영등의 요인이 설명되었다. 이는 지속적 내, 외부 환경 분석 및 핵심역량 강화를 통한 책임경영의 구현이 곧 장수경영의 핵심으로 나타나고 있다.

국내 지역대표도서관은 "도서관법"에 따른 개별 공공도서관인 동시에 광역시 도를 대표하는 도서관이다. 그러나 현 단계 대다수 지역대표도서관의 위상과 역할은 대규모 공공도서관에 불과할 정도로 취약하다. 이러한 현실에 주목하여 본 연구는 지역대표도서관의 주요 약점과 한계를 분석한 다음, 그 명칭을 광역대표도서관으로 개칭해야 한다는 전제하에 "도서관법"의 개정 보완, 수행업무의 재구성과 충실화 핵심역량과 직결되는 인력 및 운영조직 확대 등의 측면에서 위상정립 및 운영의 정상화 방안을 제시하였다.
