연구배경 : 갑상선중독성 저칼륨혈증성 주기성 마비는 갑상선항진중에서 양측성으로 주로 하지에 국한되는 이완성 마비로 현저한 저칼륨혈증을 동반하는 질환으로 젊은 동양인 남자에서 호발한다고 알려져 있다. 방법 : 저자들은 본 질환의 임상적 특징을 알아보고자 충남대학교 병원에 내원하였던 9명의 갑상선중독성 저칼륨혈증성 주기성 마비환자들을 대상으로 각종 임상적 소견들을 분석하였다. 결과 : 1) 대상환자는 9명 모두 남자였으며, 평균연령은 31.3±5.9(23~42)에 였다. 주기성 마비의 가족력은 없었다. 2) 마비 발작시 혈청 칼륨치는 평균 1.82±0.25(1.49~2.33)mmol/L로 현저히 감소되어 있었다. 3) 마비는 주로 늦은밤과 이른 새벽에 발생하였고, 계절적 차이는 없었다. 4) 유발 요인으로는 심한 운동, 과식, 과음, 감염 등 이었다. 5) 갑상선 중독성 저칼륨혈증성 주기성 마비는 칼륨이온 투여와 항갑상선선제 투여로 재발없이 치료되었다. 결론 : 주기성 마비가 동반된 갑상선중독증의 젊은 남자 환자에서 심한 저칼륨혈증 및 각종 유발인자들에 대한 주의가 필요한 것으로 생각되었다. Background : Thyrotoxic hypokalemic periodic paralysis is a well recognized complication of hyperthyroidism in mainly Oriental men, and in association with hypokalemia and flaccid type paralysis of legs. Method : Nine patients with thyrotoxic hypokalemic periodic paralysis hve been studied retrospectively by the authors at the Chungnam National University Hospital from Jan 1989 to Mar 1992 for the evaluation of clinical characteristics. Results : 1) All patients were males aged 31.3±5.9 (range 23~42) years old. 2) The average serum potassium level during paralysis was 1.82±0.25 (range 1.49~2.33) mmol/L. 3) Attacks of paralysis occurred at night and early morning. 4) The precipitating factors were severe exercise, overeating, alcohol drinking, and infection. 5) The attacks of paralysis usually disappeared after effective treatment with potassium salt and antithyroid drug. Conclusion : We thought that meticulous attention should be paid for hypokalemia and thyrotoxicosis in young patients with history of periodic paralysis.

The purpose of this study is to examine the effects of P-O fit on organizational commitment and organizational citizenship behavior in hotel industry. The framework of empirical study was established, by which the study mode] and hypotheses were formed for each variable and the operational definition was given for each. The data were collected by employees who were working at the 5-star hotels in Seoul and a total of 237 cases were used for analysis. A structural equation model was used to test the hypotheses. The results of the empirical research can be summarized as follows: First, P-O fit had positive effects on organizational commitment. Second, P-O fit had positive effects on organizational citizenship behavior. Third, organizational commitment had effects on organizational citizenship behavior.

Recently, the development of the paved track is required as a low-maintenance of conventional line. The main reason is that the line capacity and bearing of track are increased progressively. The important factors of paved track are stability and applicability. To be based on this subject, cement mortar pouring type paved track is developed. The paved track is a kind of concrete track using the prepacked concrete technique. The most important thing to design the paved track is to optimize the track structure and materials considering various conditions. Until now, the paved track is verified a various material and structure test. In this paper, it is introduce to the test construction at the urban subway main line. The test construction is completed at Dec. 2007. A major object and substance is a guarantee of construction progress on main line, track performance, construction technique for curved section, transition zone and winter season, recycling the used ballast and application of specific sleeper for sharp curved section.

The purpose of this study was to identify the relationship between personality type and GPA scores of the students who majors tourism. The data were collected from "k" tourism College students in Korea. The study used Myers-Briggs Type Indicator (MBTI) Form. MBTI test were conducted and used to analyze student"s Personality Type. The results from MBTI and GPA scores were analyzed by SPSS 12.0 Package. Students" personalities have been split into four types, E, S, T, and J type, and the result shows that ESTJ type and ESTP type students are dominant groups. The results of the analysis show that only S-I and J-P types establish a significant relationship between personality type and GPA scores. However, it is crucial to consider each student"s personality type as a basis for personalized education in order to have effective teaching strategies.

분리형 프리캐스트 방식을 적용한 주행궤도의 시공방법에 관한 연구를 위하여 현장조건 및 재료조건을 고려하여 충진재 주입실험을 분석하였다. 실험방법은 자연유하식과 펌프압송식에 대한 유동성, 주입 Hole 조건에 따른 충진성을 중심으로 분석하였다. 그 결과, 충진성은 밀폐된 공간에서 공기기포층이 중앙부에 미미하게 나타났지만 전반적으로 충진이 잘 이루어 졌지만, Cement-mortar의 유동성은 현장온도조건을 고려하여 시간제한을 다르게 적용해야 할 필요가 있다고 판단된다. 향후 추가적인 실험을 통하여 재료 및 시공 성능 평가를 할 예정이다. It is analyzed injection test of the runway applying the 3D-PST which is considering the field and material conditions for the study on the construction method. Experimental methods were analyzed according to Natural flow and motor pump type, injection test is conditions for infilling hole. As a result, the infilling overall well done. Flowing concrete is considering temperature condition of cement-mortar apply the limit time. Needed additional experiments based on result of this paper.
