Hyun Soo Kim, Jong Woon Cheon, Min Su Kim, Chang Kil Jung, Kyung Rok Kim, Jae Won Choi, Dong Woo Kang and Sun Young Kim1 Departments of Internal Medicine and Pathology1, DongKang Medical Center, Ulsan, Korea Actinomycosis is a chronic suppurative disease and caused by Actinomycosis species, principally Actinomyces israelii, which are part of the normal inhabitant on the mucous membrane of the oropharynx, gastrointestinal tract, and urogenital tract. It usually affects cervicofacial, thoracic and abdominal tissue. Cervicofacial type has the highest percentage of occurrence with 50%. Actinomycosis frequently occurs following dental extraction, jaw surgery, chronic infection or poor oral hygiene. It may also be considered as an opportunistic infection in immunocompromised patients such as malignancy, human immunodeficiency virus infection, diabetes mellitus, steroid usage or alcoholism. But, actinomycosis rarely occurs in adults with normal immunity and rare in the esophagus. We report an unusual case of esophageal actinomycosis which was developed in a patient with normal immunity and improved by therapy with intravenous penicillin G followed oral amoxicillin, and we also reviewed the associated literature.

This study investigated participants who have taken part in Hapkido continuously, in view of age, carrier in exercise, and gender and then analysed how these factors affect continuous participation in Hapkido. 1) The significant factors which enable the participants to continue Hapkido were revealed as health/physical fitness(71.67%), enjoyment / interrest (58.13%), self-protetio / guard(48.28%), phychological benefits(20.94%) 2) The factors of continuing Hapkido were different in ages, which showed significant differences in phychological benefits, skill fulfilment / challenge, accomplishment / position, charm, recreational activity. The response represented specifically in one or two areas in case of younger participants. The more aged, it showed relatively even distribution to the various responses due to the broaden span of thoughts. 3) The factors of continuing Hapkido were different in carrier, which showed significant differences in self-protection / grard, skill fulfillment / challenge, accomplishment/ position in different experiences in exercise. By the time of reaching first phase and second phase, it is thought to show the psychological effect of continuing exercise unconsciously in various areas. 4) The factors of continuing Hapkido were not different in gender, which implicated the fact that the overall attitude and thoughts on Hapkido of female participants and male participants are similar.

기업의 배당정책 결정요인에 대한 실증연구 : -중국 상해증권거래소의 상장기업을 대상으로-

김천희, 최창훈, 우춘식 숭실대학교 2009 숭실경영연구 Vol.1 No.1

본 연구에서는 1998년부터 2007년까지의 기간에서 중국 상해증권거래소의 상장기업 중에서 표본의 선정방법에 따라 A주 기업 208개를 선정하여 어떤 재무요인이 배당정책의 결정에 영향을 미치는가를 분석하는데 연구의 목적을 두었다. 연구결과를 요약하면 다음과 같다. 첫째, 수익성을 대변하는 변수인 주당순이익의 회귀계수가 배당의 유형과 관계없이 유의한 양(+)의 값을 보임으로써 수익성이 배당정책에 양(+)의 영향을 미치는 것으로 나타났다. 둘째, 기업의 투자기회와 성장기회를 대변하는 변수인 M/B비율과 총자산증가율이 A주의 주식배당과 혼합배당정책에 유의한 양(+)의 영향을 미치는 것으로 나타났다. 투자기회가 많고 성장성이 높은 기업에서 많은 배당을 지급한다는 가설을 지지하는 증거를 발견할 수 있었다. 셋째, 전기배당률의 회귀계수가 A주의 현금배당과 혼합배당에서 유의한 양(+)의 값을 보임 으로써 배당의 안정성이 배당정책에 의미 있는 영향을 미치는 것으로 나타났다. 넷째, 배당의 잔여이론을 대변하는 부채비율과 가처분현금흐름 비율이 부분적으로 배당정책에 영향을 미치는 것으로 나타났다. 다섯째, 소유구조를 대변하는 국유주 비율, 법인주 비율과 유통주 비율에서는 일관된 결론을 얻을 수 없었다. 따라서 소유권구조가 배당정책에 의미 있는 영향을 미친다고 보는 데는 한계가 있는 것으로 판단된다. The purpose of this study was to analyze which financial factors had an affect on deciding divided policy. According to some sampling criteria, in the purpose of this study 208 firms from A shares are selected and the dividend and financial data from the Shanghai Stock Exchange were used. A multiple regression analysis were adopted to empirically test the major purpose of this study with cash dividend ratio, stock dividend ratio and mixed dividend ratio as dependent variables and with the identified some determinant variables as explanatory variables. The results are summarized as follows. First, the empirical tests showed that the earning per share had significantly positive relationship with dividend policy. The regression coefficient of the earning per share had positive value in all type of dividend group. According to this results, the companies with more profit tend to distribute more dividend. Second, M/B ratio and growth rate of total assets, representing firm's investment and growth opportunities significantly affected stock dividend policy from A shares firm. It was supported the residual theory of dividend policy was supported. Company had more investments and growth opportunities, the more dividend was paid. Third, the former dividend ratio has significantly positive relationship with cash dividend policy and mixed dividend policy in sample firms of A shares. It indicates that the stability of dividend has significant influence on dividend policy. Keywords: cash dividend, stock dividend, mixed dividend, residual theory of dividend stability of dividend

Routing region modeling methods for auto-routing system is used grid and non-grid methods Although physical elements are small, the grid method has disadvantage that decrease the auto-routing speed due to constraint with size of grid and board, which in it is increase memory size Shape based type(non-grid method) used region process type and the shape located in memory as a individual element, and this element consumed small memory due to unique data size In this paper we developed PCB(Print Circuit Board) auto-routing system using the auction algorithm method that 1) Could be reached by solving the shortest path from single original point to various destination, and 2) without any memory dissipation with the best speed. Also, the auto-routing system developed by Visual C++ in Window environment, and can be used in IBM Pentium computer or in various individual PC system

Leaching characteristics and adsorption ability of Fe and Mn in the paddy soil were studied with synthetic acid rain. 1. Leaching quantity of Fe from the paddy soil by acid rain was 8 times as much as by neutral rain, and 6 times for Mn. 2. Leaching quantity was changed with heat treatment methods of sample soil (ignition or air drying), with kind of meta](Fe or Mn) and with acidity of soil (acid or netural). 3. The adsorption ability of Fe on the paddy soil was twice as much as, that of Mn. 4. Langmuir isotherm equation was c/q=20C+10 for Fe(air drying paddy soil) and c/q=160 C - 610 for Mn(ignation paddy soil). 5. Contineous column experiment showed that the adsorption ability of Mn was above 100, and for Fe, it was changed with kinds of sample soil and pouring methods.

Generally, transverse steel in reinforced concrete column serves the three-fold function of confining the compressed concrete, preventing lateral buckling of the longitudinal reinforcing steel, and acting as shear reinforcement. However, the amount of confining steel required in the form of rectangular hoops is still argument. This paper summarizes the results of an experimental program where 10 short columns with compressive strength 21MPa are designed with variable lateral confinements such as Metal Lath and Wire Mesh were tested under monotonic axial compression to failure. The columns were 300mm square and 750mm high. The purpose of this study is to investigate the ductility and strength of columns with variable lateral confinement. Test results indicate that specimen confined by metal lath and hoop, and wire mesh and hoop show 1.89 times ductility than NO.I specimen using hoop only. However, effect of lateral confinement by metal lath and wire mesh is how or same than NO.I specimen in maximum strength.

In this study our purpose is to explore the new prardigm of educational reform alternative to the current Korean educational reform. To achieve this purpose, in the first place, we axamined the limits and problems of the individualistic anthropology in the modern dominant liberal philosohy of education. Second, we discussed the ecology-centered thoughts which is considered as the philosophical foundation of a new educational paradigm. Finally, we showed the features of the new paradigm of Korean educational reform on the basis of the ecology-centered thoughts.
