The relationship between systemic bone loss(osteopenia) and loss of oral bone has been of considerable recent interest. In dentistry, some investigators have studied using human subjects, but no firm conclusion due to many obstacles have yet been obtained. From these obstacles in the assessment of human subjects, the significance of investigations with overiectomized rats has been proposed recently. Also, in ovariectomized rats, quantitative data on changes in the alveolar bone of mandible and basal bone of mandible using dual-energy x-ray absorptiometry(DEXA) were far fewer. The purposes of this study were to certify systemic estrogen deficiency-induced osteopenia by biochemical markers(serum osteocalcin(OC) & urinary deoxypyridinoline(DPD)) and bone mimeral density(BMD) of femur by DEXA and examine changes in BMD of the rat mandible by DEXA with 24-week-old female Sprague-Dawley rats. Forty eight rats were used in this study and twenty four rats were ovariectomized bilaterally(OVX) to induce systemic osteopenia and remainders were subjected to sham surgery(Sham). The experimental rats were killed at different time interval(1st, 2nd, 3rd, 4th, 6th, 8th, 12th and 16th week) for histologic examination, biochemistry analysis and BMD measurement. The results obtained from this study were as follows: On histological examination, in mandible, early degeneration of periodontal ligament, early bone resorption in alveolar bone and late bone resorption in basal bone were observed. On biochemical analysis, OC and DPD were observed statistically no significancy to predict systemic osteopenia. On DEXA measurement, in OVX group, we observed statistically significant decrease from 3rd week in distal metaphysis, statistically non-significant decrease from 2nd week in alveolar bone of mandible, and statistically significant decrease at 16th week in total mandible. From these results, it could be stated that systemic osteopenia by ovariectomy was early affected in the trabecular bone of femur and alveolar bone of the mandible whereas the total mandible was affected later.

Recently, In the advanced countries have been studied on the Parallel Kinematic Machine Tool(PKMT). PKMT has merits to reduce a machining error while switch position of workpiece for 5-plane machining. Main spindle & moving plat-form to chain many links may increase mechanical stiffness because it takes tensile & compressed strengths instead of getting bending moment. Even though there are little studies on the PKMT & evaluation of machining accuracy. In this paper introduces a test work-piece & method for evaluation of machining accuracy with PKMT.

Superficial venous thrombosis of the chest wall was first described by Mondor in 1939. Braun-Falco reported in 1955 superficial penile vein involvement in diffuse thrombophlebitis of the abdominal wall and in 1958 Helm and Hodge first described isolated superficial dorsal penile vein thrombosis. Since then, fewer than 50 cases have been reported. The clinical presentation is usually redness and swelling of the dorsum of the penis, accompanied by a palpable, tender thrombotic vein. This acute and painful disease frightens the patients, who is concerned about his fertility and sexual function. The main cause of this disease is frequent sexual intercourse. Diagnosis is based upon anamnesis, physical examination and penile sonography with color Doppler imaging. It is usually a benign disease which resolves quickly under appropriate medical therapy. We present a man who was visited for this condition and was conservatively treated.

Recently, parallel kinematic machine tool with high accuracy and stiffness is causing great concern in 5-Axis processing which is applied in manufacturing with complicated shape products. However, there are some inherent difficulties in parallel kinematic machine tool such as a collision between workpiece and tool, over-cut and under-cut, verification of tool path route in progress. To solve these problem in advance, it needs machine simulation of parallel kinematic machine tool above all things. the purpose of this study is, therefore, carried out machine simulation for parallel kinematic machine tool and accumulation of technical knowledge for the productivity and efficiency in parallel kinematic machine tool through verification of 5-Axis machining.

목적 : 우리나라의 고등학교 3학년 학생들은 대학입시를 앞두고 많은 스트레스 환경에 놓여있으나, 그에 대한 연구는 충분하지 않았다. 본 연구는 고등학교 3학년 남학생들을 대상으로 생활습관과 스트레스 정도, 스트레스 대처방법을 알아보고 생활습관과 스트레스, 성적과의 상호 관계를 살펴보고자 하였다. 대상 및 방법 : 수능시험을 치른 포항 모 남자 고등학교 3학년 454명을 대상으로 2000년 11월 29일 자기 기입식 설문지를 이용하여 성적, 스트레스량, 스트레스 해소방법을 조사하였다. 스트레스 측정은 외래용 스트레스량 측정도구인 BEPSI (The Brief Encounter Psychosocial Instrument) 번역판을 사용하였다. 결과 : 조사대상자의 성적과 생활습관과의 관계를 본 결과 생활습관 중에서 아침식사(p<0.05), 규칙적인 식사(p<0.01), 규칙적인 수면(P<0.01), 부모와의 대화(P<0.05), 흡연(P<0.05)이 성적과 통계적으로 유의하였다. BEPSI 점수는 성적 및 스트레스 해소방법과 유의한 관계가 없었다. 생활습관과 BEPSI 점수와의 관계는 규칙적인 식사(P<0.05), 부모와의 대화(P<0.05), 주 2회 이상의 음주(P<0.01), 흡연(P<0.01) 등에서 통계적으로 유의한 관계가 있었다. 건강 생활습관 갯수와 BEPSI 점수는 유의한 관계가 있었다(P<0.01). 결론 : 고3 남학생들은 건강한 생활습관과 학교성적이 비례하였고, 건강습관 갯수와 스트레스량은 역비례하였다. 그러므로 고등학교 3학년 시기에는 좋은 생활습관을 가지는 것이 중요하다. Background: There are many stressful environment in the twelfth grade students who will take an entrance examination. But the investigation about twelfth grade students were not studied enough. Therefore we investigated the relationship between life style, school record and stress in the twelfth grade students. Methods: In November 29,2000, we surveyed 454 twelfth grade male students who has taken entrance examination for a university in a high school located in Pohang. Self report questionnaire was administered to measure school record, coping method, life style and stress. Stress amount was measured by Korean-translated BEPSI score. Results: There was significant relationship between school record and life style such as breakfast. regular diet, regular sleep, enjoy conversation with their parents and smoking. School record and coping method were no significant relationship with BEPSI scores. There was significant relationship between BEPSI scores and life style such as regular diet, enjoy conversation with their parents, smoking, drinking more than two times a week. The number of healthy life styles number was significantly related to BEPSI scores. Conclusions: Healthy life style was proportional to good school record and inversely proportional to stress amount in twelfth grade male students. Therefore, we conclude that it is important to keep healthy life style in the twelfth grade.

A Study on failure strength of rock under uniaxial and triaxial compression tests was carried out for underground structural design in domestic and foreign countries recently. An experimental study was made for the core specimens of SANG-DONG tungsten mine. The results are as follows; 1. Failure strength was increasing gradually with increase of confining pressure. 2. Longitudinal and lateral strain increased in proportion to confining pressure under triaxial compression tests. 3. Stress-strain curves showed straight line to 62% of failure strength. 4. Effect of failure strength about porosity was 3.0% on the average and it represented lower value comparatively. 5. The values of triaxial compressive strength were distributed between 345 and 3082㎏/㎠, the mean value of which was 1063㎏/㎠. 6. The mean value of modulus of longitudinal elasticity(E) was 3.6X 10^5㎏/㎠ and poisson's ratio was 0.35.
