Objective : Serum uric acid has now been identified as a marker for a number of metabolic and hemodynamic abnormalities. The aim of this study is to evaluate risk factors which influence hyperuricemia in the citizens of Asan. Method : The study design was cross-sectional and research subjects were 1086 citizens of Asan. General characteristics, cigarette smoking, alcohol consumption, and past history were obtained by interview using a structural questionnaire. Also, we measured height, weight and blood pressure, and serum uric acid of the subjects. Results : The mean serum uric acid level was 5.27 ㎎/㎗ in men and 4.01 ㎎/㎗, in women, In the multiple logistic regression analysis, statically significant risk factors of hyperuhcemia were gender, body mass index, blood lead concentration, and serum creatinine. Conclusion : Our results suggest that gender, body mass index, blood lead concentration, and serum creatinine might be the most important risk factors of hyperurcemia. Education program as well as routine check-up for serum uric acid was highly recommended for the effective prevention of hyperuricemia.

The cumulative trauma disorder is a disease group of musculoskeletal systems developed by repeated work, which became greate concern in occupational health problem in Korea recently. Many paramedicals working in the department of Laboratory, Radiology, and Rehabilitation of the hospital have been engaged in the simple repetitive hard works causing cumulative trauma disorder. This is the study on the cumulative trauma disorder in those medical technicians. Total 285 (180 male, 105 female) medical technicians and office workers working in the hospital were surveyed with the self-administered questionnaires. They included the questions such as age, sex, marital status, education, height, weight, smoking and drinking history as a general characteristics and work department, kind of work, work duration, work conditions as a work characteristics. And also subjective symptoms related with the work in each region of body area were questioned. Among the work conditions, there were significant differences between medical technicians and office workers (e.g., high in medical technicians) in daily works lifting patients or heavy equipments, works moving continuously and rapidly, works with uncomfortable position, works keeping neck and upper arms in uneasy position. Complained rate of subjective symptoms was significantly higher in physical therapist and in the group of work duration over 10 years. The significant symptoms were pain, abnormal sensation, burning sensation. The significant factors affecting the subjective symptoms were female and work duration over 10 years for wrist area, female and current smoking for knee or ankle area, physical therapist, work duration between 6 and 9 years for lumbar area, female and radiologic technicians and work duration over 6 years for shoulder area. None was significant for neck area.

In this study, motion characteristics and power requirement of rotary tilling according to shape of conventional rotary blade were measured This study was performed to establish factors which needed to develop energy saving rotary blade. Starting point of edged curve of imported rotary blade was faster than that of domestic rotary blade after measuring and analyzing edged curve of rotary blade. So domestic rotary blade tills much soil than imported rotary blade. In analyzing motion of rotary blade, Rotary blade of A, D type was begun to contact at part 3. Analyzing back surface of rotary blade which contact to soil at critical λ results in contacting at e-f part. In measuring power requirement of rotary blade, specific torque and specific work of rotary blade are 160~170 kgf·m/m², 3,700 kgf·m/m³. It shows power requirement of rotary blade according to shape of rotary blade are very different.

The purpose of this study was to raise the effectiveness of learning and teaching through developing lesson plans based on ICT for electrical · electronic units in elementary practical arts of 5th grade at elementary school in the 7th national curriculum. This study was conducted by dividing into four stage(the analysis stage, the design stage, the development stage, the evaluation stage) for this purpose. For the analysis stage, after the units required to develop were selected and teaching objectives were identified, objects that lesson plans based on ICT were applied to and teaching-learning setting were grasped and the learners' final behaviors were described in detail and the content analysis were systematized. For the design stage, teaching guidance based on ICT for accomplishing learning objectives was made and its application to elementary practical arts education was invested. For the development stage, Power-Point 2000 as the writing tool which is easy to make out, correct, and edit their presentation was used. For the evaluation stage, After self evaluation and expert evaluation were conducted to identify the problems and content's errors of the developed lesson plans based on ICT, lesson plans were corrected, made up for, and completed by their results. The results of this study tested by the experts were as follows : As these lesson plans were gotten the positive marks more than the average in the three domains of the teaching plan domain, the teaching process domain, and the evaluation & the rest, it showed that they were effective materials giving a high learning drive. According to this, lesson plans based on ICT as materials to raise teaching-learning effectiveness are required.

The Korean Neuropsychiatic Association (KNPA) was founded in 1945 and has now grown to over 2000 members as of 2003. The Association's academic meeting has also been increasing in size every year. To further develop the academic meeting of the KNPA, the task force team conducted this project. We suggest several points based on analysing the abstracts of the meeting that has conducted during the last 5 years, the survey results performed at the 2002 annual meeting, the annual meeting of the American Psychiatric Association, and the academic activities of a Korean medical assoction, the Korean Society of Otolaryngology.

Recently, composite materials have widely become available to engineers. This paper briefly explains the applications of these materials and shows how these materials can be used to repair structures with damages such as crack, notch, etc. Before the fatigue test, notched and repaired specimens with thin laminate composite are prepared. Also, test apparatus is designed to perform four point fatigue test of specimens. From the experimental result, it was found that present repair technique could be used to enhance the life of damaged structures.

우리 영동대학교에서 1998년 이후 지금까지 진행하여 온 특별 주제 학습과정인 STC(Special Topics COurse)프로그램을 기존의 운영틀에서 탈피하여 한층 더 발전시킨 복합STC로 활용하고자 하였으며, 특히 이를 졸업생의 취업 및 진학의 방법으로 최대한 활용하고자 계획·운영하였다. 그 결과 취업 및 진학과 같은 진로 확립은 물론 전공지식의 확대, 자격시험 대비능력의 향상, 학생과 교수간의 유대강화 등과 같은 괄목할 만한 성과를 얻을 수 있었으며, 교수들의 산업체 방문을 통한 산학협동의 계기 마련에도 커다란 성과를 얻었다. We have upgraded the STC(Special Topics Course) program, which has been carried out in our university since 1995, to more structured program so that we could train our chemical engineering students better. This program was geared to help students find better jobs and enter well-recognized graduate schools. Consequently, we had most students successful in job searches as well as entrance exams for graduate school; besides, those who actively participated in our STC program were able to attain better professional knowledge and acquire various professional engineers certificates. On top of that, this program allowed us to build up closer relationships with our students. We also made university-industry cooperation possible through our visits to industries nearby.

A 13-year-old, castrated male, Maltese-dog was admitted to the Veterinary Medical Teaching Hospital of Chungnam National University with the history fo petechiae. On physical examination, she had petechiae and ecchymoses at her back, bilateral inguinal region, and inner part of ear pinna. CBC indicated neutrophilia and severe thrombocytopenia. A few platelets, no autoagglutination of RBC, and no spherocyte were observed. Coagulation profile demonstrated normal PT, and aPTT. No significant findings was not found on serum biochemical profile and electolytes test. FNA of a splenic mass which was found on the abdominal radiograph and sonograph demonstrated extramedullary hematopoiesis, Proteinuria was observed on urinarysis. Primary immune-mediated thrombocytopenia was diagnosed by ruling out of other underlying disease, severe thrombocytopenia, and response to immunosuppressive therapy. Prednisone and antibiotics were administered orally and parenterally, respectively. After altering prednisone to azathioprine, the number of platelets was recovered to normal range and petechiae and ecchymoses were improved.
