The purpose of this study is to exhibit fundamental data which can apply to quality and process management of structure concrete using special cement in the construction field investigating strength prediction by maturity method of concrete according to cement types. The activation energy value was derived from the experimental study that experimental factors were selected as W/C ratio of 45%, the kinds of cements of 3 levels of O.P.C, H.B.C, H.S.C and curing temperature of 3 levels of 5℃, 20℃, 35℃. Also, after investigating relationship between compression strength and equivalent ages of concrete according to cement types, the strength prediction was investigated by maturity method. As the above of results, differences between the prediction strength by strength prediction equation and the actual measurement strength were lower, therefore it is considered that the strength prediction by maturity method is possible not only concrete using normal portland cement but also concrete using special cement.

This study discribes characteristics of water spray for extinguishment of gasoline fire. Experiments are carried out for the gasoline pool fire with the atomizing nozzles. Droplet size, spray pressure, amount of water which reaches the flame base and velocity of water spray are measured to find extinguishment conditions. Air entramment due to the water spray and extinguishing process of gasoline fire by water spray are visualized. Boundary conditions of water spray for extinguishment of gasoline pool fire is quantitatively shown. As the result of experiments, it is found that the velocity of entrainment air and sprayed water are almost same and the water droplets size having small diameter under 40㎛ can not extinguish the fire because too small droplets does not reach the fuel surface.

유암종은 전신에 퍼져 잇는 장크롬친화성 세포에서 기원하는데 위의 유암종은 비교적 드문 질환으로 모든 유암종의 1.9~2.2%에 해당하며 위에 발생하는 종양의 1% 미만에서 보고되고 있다. 유암종은 일반적으로 증상이 비특이적이고 면역조직화학검사에 의해서 진단되기 때문에 과거에는 드물게 발견되었으나 최근 내시경 기기 및 술기의 발전과 검사 빈도의 증가 및 면역조직화학검사의 발달로 진단율이 증가 추세에 있으며, 드물지만 유암종에서 선암과 공존하는 예들이 보고되고 있다. 저자들은 심와부 동통을 주소로 내원한 70세 남자 환자의 상부위장관내시경 검사에서 위체상부의 대만곡에서 0.4×0.4 cm 크기의 중간 함몰을 가진 Yamada 1형의 용종과 함께 전정부의 전벽에서 0.8×0.5 cm 크기의 융기된 점막 소견을 보여 조직학적으로 각각 위유암종 및 위선종임을 확진한 후 내시경적 용종 절제술로 치료한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Carcinoid tumors are arisen from enterochromaffin cells, which are scattered throughout the body. These tumors are composed of variable numbers of cells that contain endocrine granules in their cytoplasm, which can be identified by immunohistochemistry and electron microscopy. Gastric carcinoid tumors are relatively rare tumor, the reported incidence being 1.9~2.2% of all carcinoid tumors and less than 1% of all gastric tumors. Sometimes, composite carcinoid tumors and adenocarcinoma is reported. We experienced a case of the coincidence of carcinoid tumor and adenoma at the other site of the stomach in a 70 year old male patient. Gastrofiberscope showed 0.4×0.4 cm sized Yamada type I polyp with central depression on the greater curvature of the proximal body and 0.8×0.5 cm sized focal slightly elevated mucosa on the anterior wall of the antrum. The endoscopic biopsy specimens revealed carcinoid tumor and tubular adenoma with moderate atypism, respectively. The carcinoid tumor and adenoma were removed by endoscopic polypectomy. According to the follow-up gastrofiberoscopy after 7 month later, both lesions were nearly normal mucosa except whitish atrophic change after polypectomy.

Abstract Background : Due to improvements in Korea's sanitary conditions, antibody rates to the hepatitis A virus is decreasing rapidly and admission due to the disease is increasing, Patients who were admitted for hepatitis A during the last 5 years were selected and yearly differences in admission, clinical picture, medical fees, and differences according to age and gender were analyzed. Methods : Patients who were admitted to the Seoul Soonchunhyang University Hospital during the 5 year period between May of 2003 and April of 2008 and tested positive for IgM anti-HAV were selected and their medical records retrospectively analyzed. Results : 156 subjects [91 male (58%), 65 female (42%) were selected. The average age was 29.2 years (range; 21.4-37), average admission period 12.6 days (range; 12.5-1 7.7) days, and average medical fees 2,295,151 (range; 932,097-3,658,205) KRW(Korean Won), Yearly incidence rates were as follows : 10 for May, 2003 to April, 2004, 14 for May, 2004 to April, 2005, 23 for May, 2005 to April, 2006, 69 for May, 2006 to April, 2007, and 41 for May, 2007 to April, 2008, The maximum value median of AST, ALT, and bilirubin during admission was 989 IU/L, 1999 IU/L, and 5.6 mg/dL each, Each factors were all positively correlated with the patient's age. Conclusions : Recent decrease in antibody positivity of the hepatitis A virus and subsequent surge of acute hepatitis A is a cause of rising socioeconomic costs. A large scale epidemiologic research on whether HAV vaccination should be made mandatory and health insurance applied seems to be needed. Key words : Hepatitis A, Age, Medical fees, Vaccination

It in vary difficult to guarantee the system security when security policy systems have different policy syntax in it. It means that policy data can't be transported correctly because the security negotiation could be failed. So, we have to verify the database of security policy through investigating the syntax and function of the security policy system whether wrong or not. This paper presents the parser, which is developed for the verification of security policy. The implemented SPSL parser makes offers to classify the error, to create the information of the verified security policy used for building the SPS DB and to give both the convenience of management and the flexibility of security policy.

This study is aimed at finding a possibility to make folk game developed as the traditional physical education by classifying folk game types in terms of the physical education on the basis of preceding studies and literatures, and preparing the foundation of a physical education historical study of folk games. To let folk games and the physical education approached, folk games was generally classified by realms of amusements and military sports, and a realm of a physical education historical study by amusements and military. Amusements were classified by united games/groups/individuals, and martial arts by military sports/martial arts. S study on united games out of amusements in the physical education history is extremely poor. A study on traditional physical exercises conforming to the purpose not only for the individual harmony of group lives but also for the harmony and combination of groups out of targets of physical education activities intended by the modern physical education is required, and most individual amusements are in the brink of disappearing due to the mechanical civilization these days. In the end, a study on traditional games in the physical education history may form a new game culture required by the modern society, and so their restoration as one of life physical educations is urgently required. A study realm of military arts was classified by military sports martial arts, the physical education historical study for development courses/forms/methods of traditional/drilling military arts is required. Such a traditional/drilling study still be the important data to find the intrinsic meaning of martial arts. However most studies are performed on the center of martial arts converted into now sport events.
