Household chaos, represented by high levels of disorganization and instability in the home, has been linked with suboptimal outcomes for preschoolers. The aim of this study was to examine the roles that sleep problems and executive function play in the association between household chaos and preschoolers' aggression and prosocial behavior. The sample for the study consisted of 420 preschoolers and their mothers. The mothers provided reports on the level of chaos in the home and their preschoolers' sleep problems, executive function, and social behavior, including aggression and prosocial behavior. The data was analyzed using structural equation modeling. When preschoolers' sleep problems and executive function were included in the model as mediators, the results indicated that household chaos did not have direct effects on preschoolers' aggression and prosocial behavior. Such effects were instead serially mediated by preschoolers' sleep problems and executive function, respectively. The higher the degree of household chaos, the more preschoolers displayed sleep problems and deficits in executive function, resulting in more aggression and less prosocial behavior. The findings from this study emphasize the significance of reducing household chaos in order to reduce preschoolers' aggression and promote prosocial behavior. They also underscore the need to identify additional variables that mediate the impact of household chaos on preschoolers' social outcomes.

The purpose of this study is to validate the Confusion, Hubbub, and Order Scale (CHAOS), developed by Matheny et al. (1995), in South Korea. Data of 189 parents with children under the age of 5 acquired by online survey were used for the analysis. Descriptive statistics, item-total correlation, internal consistency, confirmatory factor analysis, convergent validity were examined. As a result, 13 items were confirmed and the reliability was .881. By validating K-CHAOS, it became possible to consider the effect of physical environment, that are known to affect psychological and social development of individuals, as one of micro-systems in future studies.

In this paper, a discrete-time S-dimensional chaos circuit (S = 1,2,3,4,...) with array structure is proposed. By employing array structure which consists of 1-dimensional chaos circuits, the proposed circuit can achieve long working-life. This feature is favorable to exploit as a building block of chaos application systems to get into home electric appliances. Further more, the proposed circuit synthesized using switched-current (SI) techniques is suitable for integration. Concerning the proposed circuit, SPICE simulations are performed. SPICE simulations showed that the proposed circuit can generate the chaotic signals in spite of the fault of the building blocks of the proposed circuit. The proposed circuit is integrable by a standard BiCMOS technology.

This study examined the confronting problems in home economics and its historical and philosophical causing background, and suggested the future direction for home economics and home economics education. This study, hoped to help home economics overcoming its chaotic situation, and to establish academic characteristics through a philosophical consistency: 1. What are the significant problems which home economics has confronted, and the consequences of those problems\ulcorner 2. What are the fundamental caues of the problem\ulcorner 3.What should be the nature of home econimics to be able to overcome the confronting problems and what can be proposed for the future of home economic\ulcorner Each research question was addressed by analyzing Journal articles, theses, philosophical studies in the field. The results were as follows; 1. such problems as the ambiguity in research focus and the nature of academic charateristcs, and the limitation of research method have resulted fragmentation and specialization in the field, and the lack of philosophical research. Also they led home and family. Moreover each problem brought chaos into curriculum of home economics and that of home economics deucation. 2. The philosophical causing backgrounds of present problems are western ideas such as pragmatism, positivism, Social Darwnism and Korean ideas such as Confucian tradition, Practical Science movement in the 19th century, and modernization and industrialization from the middle of 20th century. Along with influencing historical situation these backgrounds have distorted home economics to be technical science oriented. 3. To solve these problems academic characteristics of home economics must be reestablished as practical science and as profession. This study proposed following for the future of home economics and home economics education: (1) For the future of home economics, first, it needs to recover the unity as one academic field with its focus on family by overcoming fragmentation and specialization trend in the field. Secondly, philosophical and historical studies must be carried o for the unity of all specialized field in home economics. Thirdly, home economics must try to reestablish and reflect in pratice its acadimic characteristics as practical science and as profession. (2) For home economic eduation, first, it should not be the instrument for idelogies of powerful social systems. And teacher education for home economics teachers must inclued principles of home economics and philosophy and history of home economics enabling teachers to achieve purposes of home economics. Secondly, its curriculum contents should be composed of practical ones beyond technical ones.

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.

The purpose of this study was to explore relationships between family of origin and youth transitioning from out-of-home care. Data were collected from six youths transitioning from out-of-home care and were analyzed using the phenomenological approach. The results of this study were as follows. Four categories and twelve subcategories were drawn from the meaning units. The four categories were 'chaos in separation', 're-established relations but with distance', 'completely ended relationships with the family of origin', and 'redrawing family boundaries'. First, the participants who were separated from their parents due to poverty or divorce reunited with their parents, and they appeared to continue their relationships with the family of origin after transitioning from out-of-home care. The youth were receiving various forms of support from their parents in order to be independent, and they were experiencing stable independence through this support. Second, the participants who were separated from their parents due to serious child abuse or parental death had broken relationships with their parents. The youth were independent and relied on new alternative relationships that were not with the family of origin, but they experienced somewhat unstable self-reliance. In short, participants' relationships with families of origin in this study can be defined as a tight rope between love and hate. Based on these results, child welfare practice and policy implications were discussed to help out-of-home care youth's relationship with their family of origin.

MFN provisions in investment agreements have been a tool for equitable treatment between foreign investors with different nationalities. This non discriminatory principle has been pursued by the host states for further investment promotion. However, it may be abused to bring the situation of so called "ISDS forum shopping" which might harm the stability and predictability of investment agreements by unexpectedly extending the scope of obligations. While some investment arbitral tribunals have interpreted the scope of MFN provision very broadly to allow the ISDS forum shopping, both procedural and substantive provisions have been invoked. To prevent any chaos of unclear boundary of MFN provision, some explicit MFN restrictions which would limit the scope of MFN provision are needed. Indeed, some investment agreements have included these MFN restrictions. Specifically, MFN restrictions deal with both procedural or substantive provisions to prevent ISDS forum shopping. According to the lessons from the recent examples of MFN restrictions, there must be a careful consideration on the benefits and costs of having a certain type of MFN restriction as the parties can be the host state and the home state of their investors at the same time.

This study has a research objective to suggest detailed rules and principles to transcribe geographical names in English for English version electronic map service. For this, guidelines which are used in English transcription of local geographical names in Korea and English transcription situations of Korea geographical names in foreign electronic map service were examined. Examining results of current situations showed the English transcription method of home and abroad geographical names caused the chaos because it is not homogenized. In order to identify easy and preferred transcription method for foreigners among English transcription methods about the geographical names which are used together like this, the preference of English transcription methods of the geographical names was examined targeting foreigners. Survey results showed that foreigners prefer to transcribe in Roman character (Romanization) with its semantic word together than just to transcribe the Roman character. Reflecting this preference research results, our country's geographical names were classified as Natural features, Cultural features and man-made structures, and Administrative units and the detailed English transcription rules and principles of each geographical names were suggested.
