As cultural diversity has gained a great deal of attention and the social fabric of Korean society is redefined, the number of studies on multi-cultural family homes has been growing in the area of human ecology, but relevant research is rarely found on the subject of housing. While the emphasis of housing research is on multidisciplinary approaches and empirical research is highly valued, a theoretical and methodological platform for discussing the new rising agenda of multi-cultural family homes is lacking. The purpose of this study was to explore approaches to and to discuss the issues in research for multi-cultural family homes in terms of housing theories and multidisciplinary approaches. To understand the housing related needs of multi-cultural families, this study highlights social constructionism, the ecological perspective, and feminist epistemology. These three multidisciplinary approaches were useful for generating an ontological analysis of multi-cultural family homes. Further, this study highlights two housing related theories, the microsociological and housing pathways approaches, for dealing with multi-cultural family homes. In conclusion, the five approaches were useful for exploring issues in housing research on multi-cultural family homes with appropriate research methods like hermeneutics, quantitative, and qualitative methods, and field research. Insights into using perspectives and holistic approaches might be useful for solving the problems of multi-cultural family homes in Korea.

The purpose of this study was to investigate social workers' personal experiences providing social support to multi-cultural family in a multi-cultural family center. The data were collected through in-depth interviews with 14 social workers at the multi-cultural family center, and were analyzed using a phenomenological research method. The major findings were as follows : The social workers' personal experiences with and understanding of social support were classified as 4 categories : 'source of emotional support to the multi-cultural family', 'diverse and systematic educational support', 'excessive demands on material support', and 'daily life support and connection with community network'. The social workers recognized emotional and educational support as essential factors in providing social support to multi-cultural family. However, the social workers' perceptions of material support derived from negative personal experiences stemming from excessive demands and misunderstanding for material support. These results showed that social workers at the multi-cultural family center provided multi-cultural families with social support and that they interacted with community support system and multi-cultural families to increase their satisfaction.

Following a surge of interest in multi-unit risk in the last few years, many recent studies have suggested methods for multi-unit probabilistic safety assessment (MUPSA) and addressed several related aspects. Most of the existing studies though focused on two-unit nuclear power plant (NPP) sites or used rather simplified probabilistic safety assessment (PSA) models to demonstrate the proposed approaches. When considering an NPP site with three or more units, some approaches are inapplicable or yield very conservative results. Since the number of such sites is increasing, there is a strong need to develop and validate practical approaches to the related MUPSA. This article provides several detailed approaches that are applicable to multi-unit Level 1 PSA for sites with up to six or more reactor units. To validate the approaches, a multi-unit Level 1 PSA model is developed and the site core damage frequency is estimated for each of four representative multi-unit initiators, as well as for the case of a simultaneous occurrence of independent single-unit initiators in multiple units. For this purpose, an NPP site with six identical OPR-1000 units is considered, with full-scale Level 1 PSA models for a specific OPR-1000 plant used as the base single-unit models.

Recently school food service operations are confronted with the wide spread pressures for accountability and the need to increase productivity. This paper is concerned with the make-or-buy decision framework for school food service systems considering the multi-attributes in the decision making. For the purpose of considering the multi-attributes analysis method in decision making for the school foodservice, we developed a make-or-buy decision framework using the multi-attribute analysis method, analytic hierarchy process, AHP method for school food service system. Finally, we developed a systematic and practical solution builder for a three-step decision support system in the view of 1) brainstorming for the idea generation, 2) analytic hierarchy process, AHP as a multi-attribute structure ed analysis method, and 3) aggregation logic model to integrate the results of reviewers. We developed web based program and applied it to a school foodservice problem.

The purpose of this study was to examine the effect of housing units assembled as complexes on residential satisfaction. Two analyses were performed to examine residential satisfaction of Multi-Family Housing Blocks (MFHB; complex) and Multi-Household Housing (MH; non-complex). The residents from both housing types were surveyed on nine categories of questions regarding residential satisfaction and one on overall satisfaction from their experiences. First, the t-test results between MFHB and MH suggest that MFHB has insufficient effect in terms of improvement over MH, as their satisfaction differences are either insignificant or uncontrollable. Second, the common factors affecting Overall Satisfaction of MFHB and MH are Maintenance and Residential Environments.

The multi-function radar can detect and track the low RCS targets. For this purpose the multi-function radar uses the pulse train waveform. because this waveform has high dynamic range and good SNR(Signal to Noise Ratio). But the spurious signals can also be detected by processing the pulse train waveform. Thus the multi-function radar signal processor must have the high SFDR(Spurious Free Dynamic Range). This paper describes the development of the multi-function radar signal processor having the high SFDR.
