In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

This treatise was intended to analyse the influence of physique factors on long distance records (5.000 meters and 10.000 meters ) in order to help select excellent runners. A total of 87 high school boys of age 17 were subject to analysis. They were divided into three groups: Group A with 22boys, Group B with 30 and Group C with 35. The physique factors were classified as height. weight, chest circumference. length of leg. femur length. femur circumference. crus circumference and foot circumference. 1. The Group B showed excellence in the influence of height and weight on records but yielded no significant relationship. 2. The B Group showed excellence in the influence of chest circumference on records and yielded good records in 10,000 meters race. 3. The Group A yielded excellent results in the influence of length of leg on records. especially on 5.000 meters and 10,000 meters. 4. The foot circumference had a significant influence on records in all the three groups.

The purpose of this study was to investigate the effects of four restorative materials under various oclusal loading conditions on the stress distribution at the CEJ of buccal. palatal surface and central groove of occlusal surface of endodontically treated maxillary second premolar, using a 3D finte element analysis A 3D finite element model of human maxillary second premolar was endodontically treated. After endodontic treatment, access cavity was filled with Amalgam, resin, ceramic or gold of different mechanical properties A static 500N forces were applied at the buccal (Load-1) and palatal cusp (Load-2) and a static 170N forces were applied at the mesial marginal ridge and palatal cusp simultaneously as centric occlusion (Load-3). Under 3-type Loading condition, the value of tensile stress was analyzed after 4-type restoration at the CEJ of buccal and palatal surface and central groove of occlusal surface Excessive high tensile stresses were observed along the palatal CEJ in Load-1 case and buccal CEJ in Load-2 in all of the restorations. There was no difference in magnitude of stress in relation to the type of restorations. Heavy tensile stress concentrations were observed around the loading point and along the central groove of occlusal surface in all of the restorations. There was slight difference in magnitude of stress between different types of restorations. High tensile stress concentrations around the loading points were observed and there was no difference in magnitude of stress between different types of restorations in Load- 3.

This research has been done to compare how much difference there is between their physical strength, after a physical educator has instructed 100 students (50 boys and 50 girls) ans a homeroom teacher has instructed another 100 students (50 boys and 50girls) for 9 months, who are the fifth grade students of an elementary school located in the city of Yong in The research result is as follows: 1) In case of the 100m race, the boy students instrected by a physical educator were superior to the students instructed by a gomeroom teacher by 1,44 seconds, and the girl students. by 1.81 seconds. 2) In case of the standing-long-jump, the boy students instructed by a physical educator were superior to the students in instructed by a homeroom teacher by 19.1 centimeters. and the girl students, by 11.8 centimeters 3) In case of the 600m race, the boy students instructed by a physical educator were superior to the students instructed by a homeroom teacher by 0.68 second. and the girl students, by 0.73 second. 4) In case of the ball throwing, the boy students instructed by a physical educator were superior to the students instructed by a homeroom teacher by 2.2 meters, and the girl students. by 4.1 meters. 5) In case of the boys pull up, the boy students instructed by a physical educator were superior to the students instructed by a homeroom teacher by 2.1 times, and in case of the girls' flexed arm hang, by 5.4seconds. 6) In case of the sit ups, the boy students instructed by a physical educator were superior to the students instructed by a homeroom teacher by 5.1 times, and the girl students. by 13.8 times. According to the above result, the students instructed by a physical educator were superior to the students by a homeroom teacher in all kinds of examination of physical strength. These superior records are because a physical edycator has instructed the students in the systematic and national based on a technical knowledge and given them a proper motivation. On the other hand the students by a homeroom teaher have neglected athletic classes because of main subjects and he has not given them a proper motivation because he doesn' t have enough technical knowledge. The physical educator system has not been activated because of the problems such as the unpreparedness of a physical educator training system. the ignorance of the persons concerned. the persistence of the homeroom teacher system. and the lack of an administrative support/but the elementary school physical educator system has to spread throughout the country and we have to help children improve their physical strength and achieve their balanced bodily structure by this system.

이정흔,우찬명,김홍설 忠南大學校體育科學硏究所 1995 體育科學硏究誌 Vol.13 No.1

The purpose of this research is to propose an approach to creating an atmosphere in which peace and reunification on the Korean peninsula can be achieved through north-south sport exchanges and cooperation. This proposal is intended to show how cooperative north-south sports exchanges will foster an atmosphere conductive to peaceful unification by recovering the homogeneity of the Korean people. The main characteristics of this study are as follows: First, future north-south sports exchanges should not be managed by government agencies, but will require the formation of specialized civilian organization which can carry out the necessary operations. Second, advancement of the north-south sport exchanges will require the establishment of a "North-South Sport Information Reference Center". Third, a north-south cultural facility which would include a unified sport center(including an athlete's village)must be established. Fourth, north-south sports exchanges and cooperation will require the establishment of systematic provisions for the financial support required to advance this endeavor. Fifth, in order to activate the commercial support needed for these exchanges, recognition of the importance of the endeavor will be called for from all sports minded people.

루소(J.J Rousseau)의 自然主義的 體育觀에 關한 考察

이정흔,현광석,김용진 忠南大學校體育科學硏究所 1994 體育科學硏究誌 Vol.12 No.1

We can find that Rousseau's thought of education is developed into the naturalism and training. To see his ideal concering physical education described in Emile, the training of the body offers the mental health. In addition, the function on the physical sense and power of the judgement has to be trained harmoniously. He stressed that the curiosity of sex should be diverted by exercising his body in vigorous physical pursuit and emphasized the lifelong activity because the training of the body, the recreation, and the abstinence would protect him form aging. In addition, he stressed the necessity of woman physical education and one of adult physical education for a happy domesticity. The purpose of natural physical education would train the child for domestic citizenship built the body and mind through the physical training, mamely, adequate motor skills, recreations, and health educations. Tradional subject matter was rejected by Rousseau. The studies in his naturalistic curriculum were selected to harmonize with the social, physical, and intellectual development. He practised the naturalistic learning process in fit for each stage after dividing the development stages into five stages. So, he educated the child to be growing in accordance with in ones own fashion. We found the significant facts that through the naturalistic movement the effects of physical philosophy on the contemporary education would provide for the detection of self-consciousness, self-expression, and self-realization.

서영범,김성욱,장재식,강혁주,이중현,윤병구,김욱년,이광헌,이구,유석동,양창헌,이정호,이영현,이창우,서정일 동국대학교 의학연구소 2000 東國醫學 Vol.7 No.-

자가면역성 간염은 대개 만성 경과를 가지며, 혈중 자가면역항체와 혈청 글로불린치의 상승, 그리고 조직학적으로 괴사 염증성 변화를 특징으로 하는 질환으로 아직 정확한 병인이 밝혀져 있지 않은 상태이다. 발병연령은 대개 젊은 영자(15-25세)에서 호발한다. 이 질환은 급성 간염의 임상경과를 보일 수 있으나, 심한 급성 간염이나 전격성 간염으로도 나타날 수 있는데, 이 경우 아주 나쁜 예후를 보인다고 한다. 치료는 자가면역성 간염 임상 경과의 다양성이나 병인, 병리기전의 불확실성에도 불구하고 대개 steroid 치료에 반응하는 것으로 알려져 있으며 대개 80%의 관해율을 나타내며 궁극적으로 간경변으로의 진행을 막을 수 있는 것으로 보인다. 저자들은 58세 남자에서 발생한 급성의 경과를 가지고 심한 황달을 동반한 자가면역성 간염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Autoimmune hepatitis (AIH) is a chronic necroinflammatory liver disorder of unknown cause associated with circulating autoantibodies and a high serum globulin level. The age of onset of AIH show a peak between the age of 15 and 25 years. AIH can develop and be manifested as acute hepatitis, but severe form of acute hepatitis or fulminant hepatic failure has a poor prognosis. Although AIH is likely to progress from chronic active hepatitis to cirrhosis, steroid therapy can control the disease activity, prolong survival, improve the quality of life , and defer liver transplantation. In the present report we describe a 58-year-old man who admitted because of progressive jaundice and fatigue. He was diagnosed with AIH from laboratory test result showing positivity for antinuclear antibodies, anti-smooth muscle antibodies, and negativity for hepatitis viral markers and from liver biopsy. Steroid therapy, oral administration of prednisolone, was effective in improving the liver function test. Following liver biopsy 6 months after onset shows markedly improved necroinflammatory activity.
