한상정 水原大學校 行政大學院 1998 국내석사
In case of performing a work in the big organization system, the potential problems are to find out the ability, value and performance evaluation of the workers. By doing it, We can develop their ability, and treat them with fairness and equality in proportion to their qualities and accomplishments. In this respect, the teachers' performance evaluation system is very important, and it is the base of the educational development to evaluate teachers with ration and fairness. The brief conclusions of the teachers' performance evaluation in this study are as follows; 1. The current teachers' performance-evaluation is mostly used in personnel managements for promotion, transference and prize, instead of being utilized for the original purposes. Therefore, because the deep distrust between teachers is expected, we should improve the teachers' performance evaluation so as to utilize it as materials of improving their abilities and qualities. 2. For the fair performance evaluation, a study of improving capabilities of steps In evaluation is needed and the development of the new evaluation means is reguired. If there is no guarantee of the propriety, the confidence and the objectivity in the teachers' performance evaluation, the deep discord between teachers will be occurred, and the deep disbelief in the educational society will be prevailed. Therefore, there will be foreseen the loss of working desire as well as lowering of teachers' morale. 3. To raise the objectivity of teachers' performance evaluation, we should search for the ways of participating another man power except a principal and a vice-principal. 4. We should examine the Forced-distribution method that the distribution percentage of the performance evaluation is divided into 4 grades; Su(20%), Wu(40%) Mi(30%), Yang(10%). It is irrational that We should evaluate teachers relatively in spite of being composed of the best members in their gualities, attitude and working results. 5. The objectivity and trust of the teachers' performance evaluation is low. It is said that the performance evaluation is reliable to the subjective of staffs in evaluation, and is apt to apply to the teachers related to promotion, and transference. As a result, the discord and trouble of the teachers will be serious, and the man-to-man relations will be an abstacle to improving the organization system. The performance evaluation system taking first top of the personnel management is the biggest problem in the current teachers' performance evaluation system. 6. The current promotion proportion 37.8% should be down, because most of teachers tend to think that it is too high. The performance evaluation which has no development about the new evaluation system with science and rationality can cause the competition and discord of the teachers. Therefore, the teachers' thoughts that the reflecting percentage is too high should be examined. In this study, 1 tried to find out the teachers' concern, the problems of institution and the dispute of operation, and then tried to search for the ways of improvement. Additionally it may be pointed that this report resulted from the study through the previous research, the guidance professor's advice, the consultation of preceding researchers and the present teachers' guestion papers.

하악전돌증 환자의 하악지 시상분할 골절단술에서 자가수혈의 유용성
목적 : 자가수혈은 악교정 수술에서 많이 이용되어 왔으나, 양측성 하악지 시상분할 골절단술만을 시행한 경우 자가수혈은 그 필요성이 의문시 되고 있다. 이에 본 연구는 자가수혈의 유용성에 대해 평가하고자 하였다. 방법 : 양측성 하악지 시상분할 골절단술을 시행한 환자 60명을 대상으로 하였다. 실험군 30명은 수술전 3주에 자가혈액 320ml를 예치하고 이를 수술후 6시간에 수혈 받았고, 대조군 30명은 수술전 자가혈액을 예치하지 않고 수술후 어떤 수혈도 시행하지 않았다. 두 군간에 혈색소치(hemoglobin), 헤마토크리트치(hematocrit) 및 각각의 변화량에 대해 비교, 분석하였다. 결과 : 1. 수술후 3시간부터 수술후 1일까지 혈색소치와 헤마토크리트치의 증가량은 각각 실험군에서 0.8g/dL, 0.3%, 대조군에서 0.2g/dL, 0.7%로 유의한 차이를 보이지 않았다. 2. 수술후 1일부터 수술후 1주까지 혈색소치의 증가량는 실험군에서 0.6g/dL, 대조군에서 0.3g/dL로 유의한 차이를 보이지 않았으나, 헤마토크리트치의 증가량은 실험군에서 2.5%, 대조군에서 1.0%로 유의한 차이를 보였다(헤마토크리트치 p=0.043). 3. 수술후 1주의 혈색소치와 헤마토크리트치는 각각 실험군에서 12.3g/dL, 35.6%, 대조군에서 12.3g/dL, 36.8%로 유의한 차이를 보이지 않았다. 결론 : 자가수혈의 효과는 실혈량이 많지 않은 수술에서 크지 않은 것으로 나타났으며, 혈색소치와 헤마토크리트치의 변화에 대한 분석만을 고려할 때 양측성 하악지 시상분할 골절단술만을 시행한 경우 자가수혈의 유용성은 그다지 높지 않은 것으로 사료된다. Objective : Autologous transfusion is frequently used with orthognathic surgery. The necessity of autologous transfusion has begun to question alone in bilateral sagittal split ramus osteotomy. The aim of this study was to evaluate the availability of autologous transfusion. Methods : The chart reviews of sixty patients who had undergone bilateral sagittal ramus osteotomy were done. The subjects were divided into two groups : In experimental group, 30 patients who autodonated 320ml in the preoperative 3 weeks actually received a transfusion in the postoperative 6 hours were included. In control group, 30 patients who underwent the same operation without preoperative donation and any other transfusion were included. Hemoglobin, hematocrit, and changes of these values in both groups were evaluated. Results : 1. From postoperative 3 hours to postoperative 1 day, the increase of hemoglobin(0.8g/dL in experimental group, 0.2g/dL in control group) and the increase of hematocrit(0.3% in experimental group, 0.6% in control group) was not statistically significant between both groups. 2. From postoperative 1 day to postoperative 1 week, the increase of hemoglobin(0.6g/dL in experimental group, 0.3g/dL in control group) was not statistically significant between both groups. But the increase of hematocrit(2.5% in experimental group, 1.0% in control group) was statistically significant between both groups over the same period(hematocrit p=0.043). 3. On postoperative 1 week, the value of hemoglobin(12.3% in both groups) and hematocrit(35.6% in experimental group, 36.8% in control group) was not statistically significant between both groups. Conclusion : The autologous transfusion in surgery of just a little blood loss was not effective. The most results show that there is little availability of autologous transfusion according to changes of hemoglobin and hematocrit in bilateral sagittal split ramus osteotomy.
