In today's enterprises, the complexity and enlargement of the field of the work has led the organization to be specialized, and it makes the communication and the unity more difficult between the posts. Furthermore, the overflowing of informations and knowledges, which is caused by the sudden change of the industrial society, has had an important and direct affect to the manager's behavior and decision. We can see the importance of the middle manager's position in that (1) he has to harmonize not between the top manager and workers so much as between the other middle managers accomplishing their other parts. (2) he has to exchange and hold in common the other part's information and knowledge in the process of the harmonization. (3) he has to make a diagnose and develope the plan for the solution of it, as an organization integrator. In addition to these, the middle manager's job requires the persuading, negotiating, and adjusting skill for other people's action. Therefore, this study is based on the recognition that middle manager's role becomes significant in accordance with the management specialization and it is made so that the relations of the middle manager's role, function, responsibility, and authority may be clear and the middle manager's role be built up concretely as a coordinator and negotiator, linking the upper part with the lower part, not as a mere supervisor. But the responsibility and duty of this class is really unclean. The unbalance between its responsibility and authority gives rise to many problems. The condition of the middle manager is risky, which is caused by the change of the organization This ultimately acts as a cause of impediment and gives a serious effect on the growth of enterprises. So the key manipulating the effectiveness of the organization is correcting the role and function of the middle manager, not only as the bridge of the top management and the lower management but also as a responsible person who contributes to the development of the enterprise with the subordernite's ability concentrated.

ART1(Adaptive Resonance Theory 1) 신경망을 이용하여 다음날의 시간별 전력수요를 예측하는 산법을 제안하였다. 제안한 산법은 과거 10일간의 실측전력수요로부터 수요모형을 인식한 후, 이 모형을 이용하여 다음날의 시간별 수요를 예측한다. 예측정확도를 높이기 위하여 수요모형을 평일, 일요일, 월요일, 토요일 및 특수일의 5가지로 분류하였으며, 특수일은 다시 신정, 설, 추석 및 기타 공휴일로 구분하였다. 1993년 우리나라의 수요성적 데이터를 사례로 검토해 본 결과, 지수평활화법에 비하여 우수한 예측결과를 보여 주었다. A load forecasting method using ART1(Adaptive Resonance Theory 1) neural network is proposed. The proposed method analyzes the power demand pattern of past 10 days, then predicts the hourly load of next day. To improve the accuracy of forecasting, five different day groups are defined and investigated according to the power demand, such as Sunday, Saturday, ordinary weekday, the day after holiday, and special day. The special day group includes New Year's day, Thanks giving day, New moon Year's day, and other holidays. KEPCO's hourly load data recorded between Nov. 15, 1992 and Dec. 31, 1993 are used as case study references. It is shown that the proposed method provides less forecasting error compare to the conventional exponential smoothing method.

변동원,서교일,유명희,김극배 순천향의학연구소 1995 Journal of Soonchunhyang Medical Science Vol.1 No.2
Hemoglobin AIc(HbAlc) has been known to be an index of long-term glycemic control (6-8weeks), and offers several practical advantages for screening of diabetes mellitus and evaluation of effects of treatment. Authors introduced to measure and investigate HbAlc levels by high performance liquid chromatoraphy (HPLC ; LDC Milton Roy, USA), with cation exchange column, Mono S HR 5/5 (Pharmacia). The results were as follows; 1. The mean HbAlc level in normal adult control group (n=50) was 4.13±0.25% (Mean±S.D). 2. Within-run precisions of HbAlc levels measured by HPLC were 4.39±0.01% (Mean±S.D.), 1.41(C.V.) in normal control, and 8.95±0.02% (Mean±S.D.), 1.65(C.V.) in intermittently treated diabetic patients, and 11.02±0.01% (Mean±S.D.) 2.93(C.V.) in untreated diabetic patients. 3. Between-run precision of HbAlc levels measured by HPLC were 4.35±0.01% (Mean±S.D.), 2.76(C.V.) in normal control, and 8.98±0.01% (Mean±S.D.), 1.22(C.V.) in intermittently treated diabetic patients, and 10.95±0.15% (Mean±S.D.), 3.51(C.V.) in untreated patients. 4. The peak level of HbAlc was obtained in about 9 minutes and the whole program could be completed within 17 minutes. 5. Blood specimens could be stored for as long as 8 days at 4℃ without changes of HbAlc levels. These results suggest that the measurement of HbAlc by HPLC using cation exchange column is so accurate, simple and rapid that the clinical use is more wider.

The objectives of this study are to investigate current status and problems about multilateral evaluation system. The researcher focused on the public Corporation ( K public Corporation) and evaluated the formation of evaluator's group, selection method of evaluator, evaluation method, evaluation items, and security devices such as objectiveness and fairness, feedback of evaluation results, and assistance of updating problems. Research target area is limited on the abstract of "K" public Corporation, and results of 2001 year evaluation, and evaluation feedback of this system. The summary of this study is as follows; First of all, the safety of evaluation should be considered. Social emotion, organization's particularity, the degree of evaluator's preparation should be considered. The design phase should be consisted of introduction period, extension period, and stable period so that trial and error could be minimized. Secondly, the necessity and objectiveness should be cleared. Temporary social phenomena and system acceptance of outside influence may bring about negative influence. Thirdly, accepted system should be carried out consistently. One time of multilateral evaluation cannot get general support afterwards. At fourth, the outcome of multilateral evaluation should be applied effectively. Fifthly, the maintenance of evaluator and system should be well preserved. Evaluator's anonymity should be guaranteed. Training for the evaluator should be provided to minimize the evaluation's error. Sixthly, evaluation items and the composers of evaluator should be balanced. Evaluation items should be focused according to one's ability in case of promotion while items should be carried out according to one's ability and accomplishment in case of monetary compensation Seventhly, multilateral evaluation system should be recognized widely. Without understanding of this system may bring about unnecessary disharmony and anxiety so that advertizement and education about the importance of carrying this system should be well informed.

In this study, we, in order to know the affect between cracks emanating from center circular hole with an inclusion subjected to uniform distribution load in the finite plate, studied ?? and ?? by using photoelastic experiment method. The following results are obtained. 1) As this experiment, when the size of center circular hole is R/W=0.1 or R/W=0.25 and the size of correction factor ?? is (R+C)/W<0.5, the center circular hole of any inclusion can affect. And if the correction factor ?? is (R+C)/W>0.5, the finite plate affect very much. 2) When the result of ?? is compared or the condition of same width of the finite plate and then change R the size of center circular hole, correction factor ?? of R/W=0.25 was large then that of R/W=0.1. 3) In the case of C/R, the smaller an inclusion of circular hole, the correction factor ?? was effected by length of crack, the larger an inclusion of circular hole, the correction factor ?? was effected by circular hole.
