      • 合理的 學校組織行動의 限界

        金成烈 서원대학교 교육연구소 1986 敎育發展 Vol.5 No.1

        The principles of the classical management on the basis of human rationality have good implications in terms of efficiency and goal- attainment. There is, however, the possibilty of dysfunctional, or negative Consequences. The rational decision - making models use complete rationality by excluding human subjective value factors in decision- making process, but these have many shortcomings. In the process of goal - attainment and maintenance of equillibrium of the school system, its members' interaction is very dynamic, so there are compounded rational behavior and irrational behavior each other. Korean traditional values restrict rational behaviors, and the characteristics of educational activities also restrict rationality of teacher behaviors Therefore, the conclusions are as follows : ① The basic principles of human behaviors to attain order and efficiency are rational approaches. ② But rational behaviors have limitations. ③ The limitations of rational behaviors can be overcome by irrational behaviors ④ The irrational behaviors should be permitted within the limits of maintenance of the structure and function of a system. ⑤ The rational art irrational behaviors should have a mutual supplementary relations.

        박상학,김경환,김학렬,김상훈,표경식,조용래 조선대학교 부설 의학연구소 2000 The Medical Journal of Chosun University Vol.25 No.1

        Objectives : Under an IMF bailout program, our country's financial situation forced people to change many things suddenly. Therefore, this study was attempted to search the aspects of changes of suicide attempts in order to find out how the financial crisis affects people's suicide attempts, the extreme repertoire for psychological change Method : November 21, 1997, the day issued the application of IMF bailout program, is the basic date for comparing the changes, on a certain newspaper(Dong-A daily newspaper). The condition was divided into two, namely before and after the basic date, and the characteristics of suicide were compared between two conditions. Results : The news of suicide increased more after than before the application of IMF situation. (before:105, after:158) Specially, for 30-50 years old, active age in community, the rate of suicide attempts reached twice than that of the others. After the IMF situation, the prominent reason of suicide was the financial crisis. For the type of suicide, the family suicide was remarkably increased after the IMF situation. Conclusion : The frequency of the news of suicide was higher after than before IMF bailout program. The major reason of suicide was the financial crisis. Considering that the social and economic crisis affects people's view of death, psychosocial interventions are necessary for their mental health.

      • 敎師勤務成績 評定方法 改善을 위한 硏究

        金成烈 西原大學校 1982 西原大學 論文集 Vol.11 No.-

        As long as teachers are evaluated by their administrators in a formal on-going program, they have a right to expect that evaluations will be conducted as scientifically, objectically, and fairly as possible in light of present knowledge. The characteristics for successful teacher evaluation program are (1) that the teacher as well as principals are actively involved in developing the evaluation plan and reviewing it constantly and (2) that the purpose of the program is essentially to improve instruction and help the teachers become more successful in pursuing their profession. Therefore, the results of evaluation should be open, and teachers with principals should evaluate themselves, and the evaluating factors should be composed of a list of traits, skills or behaviors of teacher. Adding rating scales to these checklists, it will be accomplished at once two purposes of teacher evaluation: improving instruction and helping teachers succeed, and to rate teachers for administrative purposes. In the content of teacher evaluation, teacher's instruction behavior and classroom performance should be emphasized more than other factors.

      • 사람 혈청트란스페린 수용체의 정제와 그 특성에 관한 연구

        이상진,김응국,김승렬 충북대학교 의과대학 충북대학교 의학연구소 1997 忠北醫大學術誌 Vol.7 No.1

        사람 트란스페린 수용체는 90-kDa의 분자량을 가진 당단백질이 둘이 결합한 단백질로 두 분자의 트란스페린과 결합할 수 있다. 본 실험에서는 사람 태반과 혈청에서 트란스페린 수용체의 고순도 정제법을 보고한다. 사람 암세포주(K-562와 SNU-1)에서 결합상수를 구해보았으며, 정상세포(적혈구와 단핵구)와 비교하여 차이가 없음을 보고한다. Human transferrin receptor is a disulfide-linked homodimer of 90-kDa glycoprotein, capable of binding two transferrin molecules. The study reports a high yield affinity purification protocol for transferrin receptor from human placenta and serum which produces the highly purified protein. We have examined the binding of human transferrin to cultured human cancer cell lines(K-562, SNU-1). Results indicate the presence of a high affinity saturable binding site(Kd=2.5 × 10-8). However, the difference between the cell line receptors in the dissociation constant have not been observed.

      • 고어텍스를 이용한 비성형 5례

        진홍률,양상권,최영석 충북대학교 의과대학 충북대학교 의학연구소 1999 忠北醫大學術誌 Vol.9 No.2

        비성형수술에 삽입하는 사용물로는 자가연골이 가장 이상적이지만 필요한 만큼의 충분한 양을 얻기가 힘들고, 수술시간이 길어지며, 흡수가 일어날 수 있다는 단점이 있다. 이러한 단점을 극복할 수 있는 이종이식물 중에서 고어텍스는 최근에 개발되어 사용이 점차 증가하고 있는 추세이지만 아직까지 고어텍스의 임상적 효용성에 대한 보고는 드물다. 저자들은 고어텍스를 5명의 융비술 환자에서 사용하였는데 3명은 연골과 같이, 2명은 고어텍스 단독으로 사용하였다. 이 중 1명에서 감염이 발생하여 고어텍스를 제거하고 늑연골을 이용하여 융비술을 다시 시행하였고 나머지 4명은 모두 만족스러운 결과를 얻었다. 평균 20개월의 추적관찰에서 이식물의 이동이나 탈출, 피부의 손상 등의 큰 부작용이 없어 고어텍스가 비성형, 특히 융비술에 유용하다고 판단되어 관련문헌 고찰과 함께 보고하는 바이다. Though autogenous cartilage remains the ideal graft material in nasal surgery, situations exist where an alternative or an additional grafting material is needed. Gore-Tex is one of most recently developed alloplastic material and has been widely used for rhinoplasty. But there are few reports about the clinical efficacy of this material in rhinoplasty. The authors used Gore-Tex as a nasal implant in 5 cases of augmentation rhinoplasty. In three patients, the Gore-Tex was used with septal or conchal cartilages because the cartilages were not enough for the needed augmentation. In one patient, the implant was removed due to postoperative infection and subsequent augmentation was done with autogenous rib catilage after infection control. During average 20 months of follow-up, complications such as absorption, mobilization, or extrusion of the implant and thinning of the nasal skin were not found. All patients were satisfied with the surgical results. From these results, Gore-Tex can be considered as an effective material in augmentation rhinoplasty when autogenous material is not available or is not sufficient for the proper augmentation.
