The purpose of this study was to explore the relationship of marital violence and marital unstability. A total of 192 marital couples in Pusan completed a structure questionnaire. The major finding were as follows : 1. Husbands and wives reciprocally inflicted psychological aggression and physical violence. 2. Violent couples who were high level of marital unstability had worse family system function than violent couples who were low level of marital unstability. Violent husbands who were high level of marital unstability were disengaged and chaos family system. 3. Husbands inflicted violence toward their wives when husbands had the contempt of communication style, and their family function were disengaged level. Wives inflicted violence toward their husbands when wives had the contempt of communication style. Couples who had high level of marital unstability were more likely to violent and were disengaged level on Circumplex Model.

In systematic tuning of digital STC parameters, systems with time-varying parameters and systems with time-varying delays are studied individually because of many preconditions and difficulties. In order to eliminate all these difficulties effectively, the expert control technique is required to enhance STC control functions. In this paper, an expert controller, a STC utilizing expert control technique, for process control is designed. The expert controller is composed of an unstability indicator for detecting plant unstability, an expert back-up controller and an expert STC which are switched each other by the unstability indication, and expert system with knowledge base and inference engine. This expert controller is able to perform control functions successfuly for the following` 1) a system which has unknown and time-varying delay time, 2) a time-varying system which has unknown parameters, and 3) a system with minimun and non-minimum phase. The robust control function is demonstrated by computer simulations.

This paper examined whether strategic decision-making are related to its performance, using a empirical study. Variables of strategic decision-making process were procedural rationality, political behavior, and application of information technology, moderating variable was environmental unstability. The findings suggested that relations between strategic decision-making process and its performance was strongly correlated, but environmental unstability was not moderating for its performance.

The purpose of this study is to investigate the relations between Wives' marital satisfaction and Divorce attitude as a basis building in marital stability . A measurement tools used for this study are marital satisfaction scale, which was adapted and reproducted from Dyadic Adjustment Scale(DAS) developed by Spanier and Divorce attitude Scale, which was developed by researcher refer to preceding study connected with a cause of divorce. The subjects were 354 married women dwelling in Seoul. Statistical methods such as frequency, percentile. mean , standard deviation, one way ANOVA, and Pearson Correlation were used for data analysis. The results of this study are as follows; 1) there is the tendency to high marital satisfaction group rather more than low marital satisfaction group and to permissional attitude group rather more than negative attitude group about divorce attitude. 2) There was difference in marital satisfaction by number of children, wives's educational level, parents marriage happiness. While, there was no difference in marital satisfaction by length of marriage, family income, wives employments status, marriage pattern. 3) There was partially difference in wives' attitude toward divorce by wives educational level, family income. Both there was no difference in wives attitude toward divorce by the other factors. 4) wives' attitude toward divorce correlates with marital satisfaction. The correlation coefficients is 283 significantly of .001 level. The more satisfaction wife feels about her own matrimony. the more negative a attitude she has toward divorce. This menas that attitude toward divorce depends upon their matrimony. 5) The four type of marital stability are as follows; high marital stability type, high subjective unstability type, high objective unstability type, high marital unstability type.

Hull-Mounted Sonar(HMS) has been the main equipment to detect and track underwater threats like torpedoes and enemy submarines. The HMS has short warming-up time and is employable independently with sea-state and weather condition. But these bad environmental condition and ship maneuvering make ship's roll and pitch. Ship's roll and pitch make unstability of sensor position, then cause degradation of the HMS performance. In this paper, we will show how the unstability influences the HMS performance, propose the 'Beam Stabilization Beamforming Technique' to overcome these phenomenon. And present the effectiveness of proposed technique by comparing with conventional beamforming result.

To cope with increasing power demand in metropolitan area, the power system in Korea has equipped with unit generator of large capacity, high density and uneven distribution, and transmission line of long distance, large capacity and high voltage. As the power system growing up enormous, it has become difficult to maintain the standard voltage in case of radical fluctuation of load or severe change of voltage by power system fault for its weakness of responsive characteristics although the power condenser has been installed to solve the unstability by lack of reactive power. Consequently, we review harmonic wave production and control characteristics to solve unstability problem of voltage in northern metropolitan, to reduce transmission restriction cost and to minimize load shedding by relocation of SVC (Static Var Compensator), which is highly effective for improvement of responsive characteristics for radical voltage fluctuation.

조선조 태조 7년(1398년)에 창건된 후 수 차례의 중수와 보수가 이루어진 숭례문은 현재에 이르러 극심한 환경의 변화에 의해 구성 암석이 매우 심하게 풍화되었을 뿐 아니라 암석 표면에 박리, 박락 및 균열 등이 발달되어 구조적 안정성에 대한 문제가 야기되어진 것으로 생각된다. 숭례문을 이루는 암석은 대부분이 화강암류이며 대체로 심하게 풍화되어 검게 변색되어 있을 뿐만 아니라 양파껍질 구조, 표면박리, 박락, 균열 및 가장자리 박락 등 여러 훼손 현상이 발달되어 있다 육안관찰에 의해 조사되어진 이러한 훼손양상들의 특징을 바탕으로 하여 성인적으로 구분하면 심한 풍화에 의해 나타나게된 표면박리와 박락, 양파껍질 구조, 그리고 편중된 하중에 의한 것, 충격에 의한 것, 그리고 원인을 알 수 없는 것 등으로 분류할 수 있다. 따라서 앞으로의 보존대책 수립을 위해서는 이러한 훼손양상들에 대하여 정량적인 방법에 의해 규명되어진 원인과 이를 바탕으로 구조적 안정성을 정밀 진단한 결과를 기초로 해야 할 것으로 생각된다.
