Aggregate planning coordinate the control variable over long-term to apply a demand variable and forcasting. In order to necessary the goal that doesn't make an inter-contradiction and explicitly defined. We made a considerable point of system approach for scheduling establishment. It include the control variables of aggregate planning : 1) employment 2) over time working and idle time 3) inventory 4) delivery delay S) subcontract 61 long - term facility capacity. Each variables composed of pure strategy as like a decision of inventory level, a change of employment level, etc. md alternative costs make a computation on the economic foundation. But the optimum alternative costs represent the mixed pure strategy. The faults of this method doesn't optimum guarantee a special scheduling as well as increasing a number of alternative combination. Theoretical, Linear Decision Rule make an including all variables, but it is almost impossible for this model to develope actually And also make use of the aggregate planning problem for developing system approach : LDR, heuristic model, Search Decision Rule, all kind of computers, simulation. But these models are very complex, each variables get an extremely inter-dependence. So this study be remained by theory level, some approach methods has not been brought the optimum solution to apply in every cases.

Purpose: This study was designed to identify nurses' perceptions and educational intentions regarding natural childbirth control (NCC) methods. Method: The participants were 313 nurses working at three general hospitals in Seoul. They were asked to complete a questionnaire composed of scales measuring knowledge and perceptions childbirth control methods, awareness of bodily changes in ovulation phase, perceptions of fetal life, which were developed by the author. Also, Chang's (2002) Sexual Autonomy Inventory was utilized. The data were analyzed by the SAS program. Results : Methods of condom and rhythm were considered to be more useful for childbirth control than other methods. Only 34-54% of them knew exactly about the NCC methods using menstrual cycle, body temperature, and mucus. The mean scores of sexual autonomy and awareness of bodily changes in ovulation phase were 3.8 and 3.4 out of 5, in respect. Educational intention was different statistically by the age, marital status, future intention to use NCC methods, and perception of educational need for NCC methods. Conclusion : Nurses' perceptions and educational intentions regarding NCC were low, especially in nurses who were married. It is recommended to encourage nurses to learn NCC methods for clients education.

연구목적 : 부모의 정신병리가 아동의 적응기능과 정신병리에 영향을 미친다고 알려져 있다. 또한 우울한 어머니는 자녀들의 행동에 대해 더 부정적으로 판단하며, 더욱 비판적이며 강압적인 양육방식을 취하게 되어 모자관계에 부정적인 영향을 미치게 된다. 저자들은 주의력결핍 과잉행동장애 진단을 받은 환아의 보호자를 대상으로 우울, 불안, 감정표현불능, 스트레스반응의 정도를 알아보고자 하였다. 방법: DSM-IV 진단기준에 의해 주의력결핍 과잉행동장애로 진단된 환아 38명의 보호자를 대상으로 하였고, 나이와 성별을 맞춘 16명의 자원자를 건강대조군으로 하였다. 환아 보호자군과 건강대조군에 대하여 Beck의 Beck Deperssion Inventory(BDI), Spielberger의 State-Trait Anxiety Inventory(STAI), Taylor의 Tronto Alexithymia Scale (TAS), 고경봉의 스트레스반응척도(SRI)를 사용하여 두 군 간의 차이를 비교하였다. 결과: 1) 환아 보호자군과 대조군의 BDI 평균점수는 각각, $16.4{\pm}7.1,\;10.9{\pm}5.5$점으로 통계적으로 유의한 차이를 보이고 있었으며 (p=0.011), BDI 점수 21점을 절단점으로 하여 21점 이상을 우울증이 있다고 했을 때, 환아 보호자군에서는 7명(18.4%)이 해당되었으나, 대조군에서는 해당되는 경우가 없어 두 군간의 유의한 차이가 관찰되었다(p=0.021). 또한 우울증이 있는 보호자의 자녀에서 주의력결핍 과잉행동장애가 발생할 가능성은 그렇지 않은 경우에 비해 1.516배 높았으며 이러한 관련성은 통계적으로 유의하였다(95% 신뢰구간=$1.235{\sim}1.862$). 2) 환아 보호자군과 대조군의 스트레스반응척도의 평균점수는 각각, $44.2{\pm}20.2$점, $26.5{\pm}16.8$점이었고, 이러한 차이는 통계적으로 유의하였다(p=0.006). 3) 상태불안척도 및 특성불안척도, 감정표현불능척도에서 두 군간의 유의한 차이는 관찰되지 않았다. 결론: 이상에서 주의력결핍 과잉행동장애 환아의 보호자군은 그렇지 않은 군보다 많은 우울증상과 높은 정도의 스트레스반응을 보이는 것이 확인되었다. 주의력결핍 과잉행동장애에 대한 치료적 접근에 있어서 환아보호자의 정신병리에도 관심을 갖고 이에 대한 통합적인 접근이 필요할 것으로 사료된다.

Automated Storage and Retrieval System (AS/RS), which is an element of Computer Integrated Manufacturing (CIM), is a widely used material handling equipment with conveyors and Automatic Guided Vehicles (AGVs). Until now the evaluation of operational policies of AS/RS and control algorithms is done theoretically or by computer simulations. In this study, a real-time control and monitoring software of an AS/RS is also developed by making actually moving AS/RS miniature. A PC-based real-time monitoring program can control the AS/RS directly through the communication port. The monitoring program has additional functions such as storage/retrieval management, inventory management, and statistics management. The program can not only collect the necessary statistics but monitor the current action of the AS/RS concurrently.

The purpose of this study was to develop 『Korean Maternal Behavior Inverntory』(KMBI). The subjects were 712 mothers of 4th-6th grade elementary school children from 5 urban cities in Korea. Item analysis. Cronbach's α, Pearson's r, Factor analysis, and Percentile norms were conducted for the purpose of the study. The major findings were as follows; 1. By the method of item analysis and factor analysis, 51 items were selected for the scale of maternal behavior. 2. A factor analysis showed 7 factors(Reasoning guidance, Affect, Antliorian Control, Achievement, Overprotection, Active Involvement, Limit Setting) as separated domains from each others. 3. The reliablity coefficient of the scale was ranged from 62 to 81 sufficient to secure reliability. 4. Percentile ranks were drived from the total score and quartiles were calculted for the each of seven factor's scores. The present study presents a potentially highly useful way of measuring maternal behavior of 4th-6th grade elementary school children in Korea.

Objectives: This study was aimed to investigate the emotional state and personality characteristics of alopecia aerata patient and to determine whether these characteristics are similar with those of neurotic patient. Methods : 20 alopecia aerata patients, 20 neurotic patients, and 20 normal healthy controls were studied. Beck Depression Inventory(BDI), State and Trait Anxiety Inventory(STAI) and Korean standardized edition of Catell's 16 Personality factors Questionnaire(16PF) were used for assessment. Results: 1) Total score of BDI was higher in neurosis group than alopecia aerata group and normal control group(p<0.05). Inspire of statistical non-significance, total score of in alopecia aerata group was higher than normal control group. 2) Total scores of state anxiety and trait anxiety in alopecia aerata and neurosis group were significantly higher than normal control group(p<0.001). 3) In first-stratum source traits of 16PF, normal control group was significantly higher than alopecia aerata group and neurosis group in B-factor(intelligence) and C-factor(ego-strength)(p<0.05). Alopecia aerata group and neurosis group were significantly higher than normal control group in O-factor(guilt-proneness) and $Q_4-factor(tension,\;anxiety)$(p<0.001). 4) In second-stratum source traits of 16PF, alopecia aerata group and neurosis group were significantly higher than normal control group in ANX-factor(anxiety)(p<0.05). Conclusions : These results suggest that emotional state and personality characterstics of patients with alopecia aerata are a distinguishable different to compare with normal control, and are very similar with those of neurotic patients. The authors propose that psychiatric management in patient with alopecia aerata will be more benificial.

재고 관리 정책은 크게 정기 점검 재고 정책과 연속 점검 재고 정책의 두 가지로 구분할 수 있다. 정기 점검 재고 정책에는 (R, Q), (R, S), (R, s, S) 등의 재고 정책이 있으며, 연속 재고 점검정책에는 (s, Q), (s, S) 등의 재고 정책이 연구되어 왔다. 공급망 관리는 하나의 기업이 아닌 관련된 모든 기업을 대상으로 하는 기법이며, 급변하는 기업 환경에 적극적으로 대응하고자 많은 기업들이 관심을 기울이고 있는 분야이다. 그리고 공급망 관리의 최종 목적은 고객의 만족도를 최대화시키는 것이다. 일반적으로 재고량과 고객의 만족도는 서로 상반되는 양상을 보인다. 따라서 각 기업에게 있어서 적절한 재고 정책의 수립은 매우 중요한 일이다. 그러나 고객 수요 패턴의 불확실성으로 인하여 공급망의 상위 단계로 갈수록 재고 변동폭이 커지는 양상을 보이는 등 적절한 재고 정책을 수립하는 것은 쉬운 일이 아니다. 더구나 취급 제품이 여러 개일 때는 공급망 전체의 재고 비용을 최소화할 수 있는 각 기업의 최적 재고 정책을 수립하기란 쉽지 않다. 따라서 본 연구는 복수 제품에 대하여 수요 패턴이 불확실한 공급망 모델을 가정하여 전체 공급망의 재고 비용을 최소화할 수 있는 각 기업의 재고 정책을 수립하고자 한다. 추계적인 양상을 보이는 수요 패턴에서 동적 계획법을 이용하여 (s, S) 재고 정책의 적합한 재주문점과 목표 재고점을 찾고, 시뮬레이션을 통해 그 결과를 검증하는 것이 본 연구의 목적이다.

Purpose: The purpose of this study was to identify the effect of supportive nursing intervention on the anxiety and nursing satisfaction of mothers with children undergoing open-heart surgery. Methods: The research design involved a non-equivalent control group pretest-posttest non synchronized design. The subjects consisted of 43 mothers of children who were expected to undergo open heart surgery, and were divided into two groups; an experimental group of 22 and a control group of 21. The experiment was administered to the experimental group a total of four times, following supportive nursing intervention protocols. The research tools used were Spielberger's State Anxiety Inventory for anxiety and Park Jung-Eun's nursing satisfaction. The data were analyzed using the $x^2$-test, and t-test with SPSS/WIN 12.0 program. Results: Hypothes 1, 'The experimental group who are given supportive nursing intervention will have a lower anxiety score than the control group' was supported(t=5.658, p=.000). Hypothesis 2, 'The experimental group who are given supportive nursing intervention will have a higher nursing satisfaction score than the control gropu wasl supported(t=-9.549, p=.000). Conclusion: The supportive nursing intervention protocol was effective in reducing anxiety and increasing the nursing satisfaction of mothers with children undergoing open-heart surgery.
