안병훈,남보우 한국경영과학회 1986 經營 科學 Vol.3 No.1
본 고에서는 불확실성을 고려한 전원개발계획방법에 대하여 간단히 소개하였다. 수요의 불확실성에 대하여 예를 들어 소개하였지만 연료비 등의 불확실성도 분석할 수가 있다. 우리는 자주 확정적 전원개발계획모형(WASP, EGEAS 등)의 결과를 최적으로 받아들인다. 그러나 그 모형의 최적계획은 계산에 사용되는 모든 자료가 반드시 미래에 그대로 나타난다는 가정하에서 만들어진 것이다. 이러한 가정을 간과하고 그 결과를 받아들인다면 커다란 오류에 빠질 것이라고 IEEE위원회는 경고하면서 불확실성을 고려한 전원개발계획 모형의 운영과 개발이 필요하다고 지적하고 있다. 한국의 전원개발계획의 환경(수요, 연료비, 건설비, 기술, 환경규제 등)은 불확실하며 이러한 불확실성에 얼마나 탄력적으로 대처하느냐가 2000년대를 향한 전원개발계획의 가장 큰 과제라 하겠다.

선형계획을 위한 Matrix Generator/Report Writer [PDS/MAGEN] 소프트웨어
안병훈,남보우 한국경영과학회 1984 經營 科學 Vol.1 No.1
이 글에서는 PDS/MAGEN이란 무엇이며 그 사용방법은 어떻게 하고 어떤 면에서 장점을 가지고 있는가를 살펴보았다. PDS/MAGEN도 컴퓨터의 다른 소프트웨어와 마찬가지로 사용법을 새로 알아야 하지만 APEX 등 선형계획 문제를 위한 소프트웨어를 사용할 때 매우 편리하다. 일단 문제가 구성되면 선형계획법이나 PDS/MAGEN의 전문가가 아니더라도 선형계획법을 쉽게 사용할 수 있으므로 실제 업무에서는 매우 필요한 소프트웨어라 하겠다. PDS/MAGEN은 현재 KAIST부설 전산개발센타내 CDC Cyber 174에 장착되어 있어, 기타 다른 기종에 적합한 소프트웨어들도 보급 판매되고 있으며, 이의 도입 적용은 효율적인 선형계획기법 응용의 필요불가결한 소프트웨어라 하겠다.

장기간의 크레아틴 구강 투여와 웨이트 트레이닝이 체구성비의 변화에 미치는 영향
이한경,채지원,안병훈 龍仁大學校 體育科學硏究所 1999 體育科學硏究論叢 Vol.9 No.1
The purpose of this study is to examine the effect of long-term oral creatine(Cr) supplementation of weight training on body composition. In order to conduct this study, 10 physical education students in optimal physical condition were chosen. The test subjects were divided into 2 groups : Cr supplement group, non-Cr supplement group. In the first stage, the Cr supplement group receved 20g of Creatine monohydrate for the first 4 days, and 5g per day for 54 days, thereafter. All exercise studies were conduced to variable resistance training for 1 hour, three times per week. The training involved seven different exercise, including leg press, bench press, leg curl, leg extension, squat, shoulder press, and sit-ups. Each exercise consisted of 5 set of 12 repetitions at 70% of one repetition maximum(IRM). The IRM values were determined before training and after 8 weeks of training. 1) In terms of body weight, there was no significant difference between the Cr supplementation condition and non-Cr supplementation condition (p>0.05). However, among the Cr supplementation condition, there was a noticeable increase in body weight than in non-Cr supplementation condition. 2) In body fat percentage, there was no significant difference between the Cr supplementation condition and non-Cr supplementation condition (p>0.05), but in the Cr supplementation condition, there was a markedly lower level of body fat percentage than in the non-Cr supplementation condition. 3) In body fat mass, there was no significant difference between the Cr supplementation condition and non-Cr supplementation condition(p>0.05). However, in the Cr supplementation condition, there was lower level of body fat mass than in the non-Cr supplementation condition. 4) In terms of lean body mass(LBM), there was no significant difference between the Cr supplementation condition and non-Cr supplementation condition(p>0.05), but in the Cr supplementation condition, there was higher level of LBM than in the non-Cr supplementation condition. 5) In the creatinine level, there was no significant difference between the Cr supplementation condition and non-Cr supplementation condition(p>0.05). However, in the Cr supplementation condition, there was higher level of creatinine and non-Cr supplementation condition. 6) In the 1RM, there was no significant difference between the Cr supplementation condition and non-Cr supplementation condition(p>0.05), but in the Cr supplementation condition, there was higher level of 1RM than in the non-Cr supplementation condition. All these findings are in agreement with previous studies. Based on the results of this, we have found that Cr supplementation and 8weeks weight training decreased body fat, while increasing LBM and muscle mass.

Objectives : This study aimed to describe the demographic, clinical and offense characteristics of the patients with Schizophrenia who committed parricide. This study also investigated the risk factors of parricide by comparing with characteristics of stranger killers to prevent the tragic offense. Methods : The sample consisted of 88 schizophrenic patients who committed homicide, 59 of them committed parricide and 29 of them killed strangers. Medical chart review regarding demographic and clinical characteristics as well as offense Characteristics was conducted. The information that was difficult to be obtained through chart review was acquired by direct interview. Results : Parricide group had earlier age of onset, more conflicts with the victims, more violence history toward victims and more offense provoking events than stranger killing group. Parricide group showed higher rate of past treatment than that of stranger killing group. However drug compliance at the time of offense was low in both groups. Offense provoking events in the parricide group included blaming, threatening a forced hospitalization or medication toward patients. The most common Psychiatric symptoms associated with homicide were threat/control override (TCO) symptoms, delusional perception, commanding auditory hallucination and especially with parricide, Capgras syndrome (CS). Conclusion : Interaction between psychotic symptoms such as TCO, CS and underlying emotion toward victims are likely to be associated with parricide. Mental health professionals are expected to play an important role in preventing this tragic offense by active history taking of the violence and effective management with active caregiver education/intervention of intrafamilial conflicts.
