김경한(Kim Kyung-Han) 서울행정학회 2005 한국사회와 행정연구 Vol.15 No.4

For the past ten years, Korean government have drove the government reform but many questions on the performance of the reform are raised by many researchers. The objectives of this study are to evaluate the performance of various government reform measures, to find out the obstacle factors to make those reform measures fail and to suggest the desirable methods and strategy of government reform. In order to achieve those research objectives, I did evaluation synthesis through content analysis on ten theses analysing the performance and the operation realities of the performance-based management programs such as Performance-based reward system, Management by objectives(MBO) and Open-system in higher civil service, which were introduced to Korean government as the tools of government reform during the period of Dae Jung Kim's administration. In conclusion, the performance-based management programs including Performance-based reward system, MBO and Open-system in higher civil service have no effectiveness because those programs are failing to accomplish the introduction objectives of each programs. The major reasons why those programs don't have effectiveness are identified as the cultural restraint, which occur by cultural inconsistency between the culture of public organization and the reform measures and cause government reform not to success. In addition, it is found out that symbolic politics is the main cause to push on with the introduction of performance-based management programs in spite of their incongruity to public culture and the probability to have no effectiveness.

Two methodologies for predicting thermal relaxation time of tissue subjected to pulsed laser irradiation is introduced by the calculation the optical penetration depth and by the investigation of the temperature diffusion behavior. First approach is that both x-axial and y-axial thermal relaxation times are predicted and they are superposed to achieve the thermal relaxation time (${\tau}_1$) for two-dimensional square tissue model. Another approach to achieve thermal relaxation time (${\tau}_2$) is measuring the time required for local temperature drop until $e^{-1}$ of the maximum laser induced heating.

Learning specific behavioral objectives (SBOs) of 39 subjects in medical school have been used to criteria not only for teaching and evaluation of medical students but also for the national medical li censing examination for physician and selection examination for internship since 1993. In order to prepare the information and data for future revision of SBOs of medical school, author compared with the SBOs of 39 basic and clinical science subjects using selected 20 items of SBOs as the key of study. The analyzed results were as follows: 1. The repetitions of a few sort of same SBOs were founded among subjects and even in same subject by difference chapter with the frequency of 2-11 times. 2. Marking the level of SBOs as B was not consistent according with different subjects or even in same subject between difference chapters. 3. Some SBOs were inappropriately listed in less related subjects. For further improvement of learning specific objectives in medical school, it would be necessary to develop the revision task of SBOs for the education committee of each medical school with cooperation of the subject objective committee of The Korean Medical Association and The Korean Society of Medical Education.

안구의 운동은 시각 환경에서의 진행중인 정보처리와 관련된 지각적, 인지적 과정을 밀접히 반영하는 중요한 지표로서, 특히 공간 지각과의 상관은 비교적 명확히 확립되어 있다. 본 연구는 공간지각에 관여하는 안구운동의 특성을 파악하여, 공간지각을 반영하는 안구운동 지표를 개발한다는 목표 아래, 피험자가 느끼는 공간의 확장과 축소의 특성을 이중도약과제(double-step paradigm)를 사용하여 관찰한 것이다. 이 중도약과제는 도약(saccadic)안구운동의 오차를 유발시키는 실험기법으로, 두개의 시각자극을 하나씩 연속적으로 보여주되, 두번째 자극은 안구운동이 일어나는 도중에 제시하는 것으로서, 인위적으로 왜곡된 공간에 대한 피험자의 공간적응을 관찰하는데 사용되었다. 이 과제는 다시 자극의 이차도약 방향에 따라 축소감 조건과 확장감 조건으로 나뉘었고, 머리운동의 역할을 판별하기 위해 머리를 고정한 조건과 머리를 자유롭게 한 조건으로 분류되었다. 그 결과 머리가 고정된 상태에서는 축소감 조건에 대한 적응이 확장감 조건에서보다 더 빨리 일어나고, 그 적응후의 시선이동의 변화량 에서도 축소감 조건이 더 크게 나타났다. 또한 머리를 자유롭게 할 경우 공간 지각의 정확성이 증가하며, 축소감과 확장감 경험속도의 차이가 약 49.2%까지 해소 되었으나, 여전히 축소감의 경험이 더 잘 일어났다.

Neuromyelitis optica (NMO) is an idiopathic inflammatory demyelinating disease, characterized by optic neuritis and myelitis. NMO is a very uncommon and serious neurologic manifestation of Sjogren`s syndrome. We report on a 32-year-old female with NMO as central nerve system involvement of Sjogren`s syndrome. She had a transverse myelitis ten years ago and did not have symptoms for a long period of time. She visited the emergency center because of worsening weakness of both limbs. She had an appendectomy three days ago before hospitalization. Cervical spinal magnetic resonance imaging showed increased signal intensity in T2-weighted images from the cervical (C2) to the upper thoracic (T4) spinal cord. As serum NMO-IgG was positive, we diagnosed neuromyelitis optica and treated with high dose steroid, but failed. Therefore, we treated with plasmapheresis and the patient was discharged without any neurological deficits.

마취통증의학과 임상실습은 지식, 수기, 태도 영역에서 고르게 평가되고 있는가?

김경한(Kyung Han Kim) 한국의학교육학회 2003 Korean journal of medical education Vol.15 No.3

Purpose: This study was performed to evaluate whether the student knowledge, skills, and attitudes in anesthesiology clerkships were properly assessed in 18 medical schools. Methods: The author examined the survey questionnaire returned from anesthesiology professors of 8 medical schools planning to be accredited and self-assessed reports published by 10 accredited medical schools. Results: The student knowledge (50%) was given a higher value in the evaluation than skills (25%) and attitudes (25%). The student knowledge was mainly evaluated using oral/written examinations, reports, recording of patient s data, and case/article presentations. The student attitude was assessed using only attitudes and attendance items. At more than half of the 13 schools, student skills were assessed based on 15 skills including insertion of iv line, intubation, blood pressure measurement, airway keep, CPR, monitoring, iv fluid /transfusion setting, arterial blood gas and Ambu ‘bagging in order of frequency. However, student skills were not evaluated in 3 of the 18 schools. Conclusion: The evaluation process should be performed adequately for student knowledge, skills and attitudes in anesthesiology clerkships. Moreover, It is inappropriate to include attendance in the student s attitude evaluation as attendance is mandatory in clinical clerkship. These results suggest that the student s clinical performance (i.e., skills and attitudes) should be evaluated objectively by using OSCE, or CPX.
