Purpose: The purpose of this study was to develop a tool to assess the severity of illness in high risk newborns. Method: The research design was a methodological study. The tool was developed in 4 stages: first, preliminary items were developed based on a questionnaire about the severity of illness index that was given to 8 health professionals in Neonatal Intensity Care Units (NICU) second, a panel of specialists reduced the preliminary items using 3 validity tests; third, final items were selected from the results of a pre-test. Finally, from July 2005 to May 2006, reliability and validity were tested with a sample of 160 high risk newborns admitted to the NICU. Results: The final tool to identify the severity of illness index in high risk newborns consisted 39 items and Cronbach's alpha coefficient for internal consistency was .922. Using factor analysis, 4 factors were extracted and these factors explained 54.451% of the total variance. Conclusion: The instrument for assessing the severity of illness in high risk newborns developed in this study was identified as a tool with a high degree of reliability and validity. In this sense, this tool can be effectively utilized for assessing and implementing care for high risk newborns.

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.

This study aims to establish a new methodological framework for the evaluation of the evolution of the reliability of plain concrete for pavement vs number of cycles under flexural fatigue loading. According to the framework, a new method calculating the reliability was proposed through probability simulation in order to describe a random accumulation of fatigue damage, which combines reliability theory, one-to-one probability density functions transformation technique, cumulative fatigue damage theory and Weibull distribution theory. Then the statistical analysis of flexural fatigue performance of cement concrete tested was carried out utilizing Weibull distribution. Ultimately, the reliability for the tested cement concrete was obtained by the proposed method. Results indicate that the stochastic evolution behavior of concrete materials under fatigue loading can be captured by the established framework. The flexural fatigue life data of concrete at different stress levels is well described utilizing the two-parameter Weibull distribution. The evolution of reliability for concrete materials tested in this study develops by three stages and may corresponds to develop stages of cracking. The proposed method may also be available for the analysis of degradation behaviors under non-fatigue conditions.

Recently, The Analog TV has been being replaced by digital TV. This dues to the advantage of digital TV that sends data as well as audio/video stream to the receiver. But there are no standards or rules for processing the data. So, most companies or developers process the data in separate methods. This absence of standards or rules for processing the data causes many confusions and waste of time, money, man power. This Thesis proposes the solution of the problem not based on standardized respect but methodological respect. This solution is using XML in producing and playing the broadcasted multimedia contents and data. We believe that this solution saves much man power, time, money and increase reusability of expensive broadcasting contents.

Purpose: The purpose of this study was to develop a nocturnal emission and menstruation education program using CAI for Korean elementary school children. Methods: The research design was methodological study a ISD model 4 fields into sub contents in each field of the nocturnal emission and menstruation by CD titles. And to verify the effect of the education program, performance evaluation of the educational program for structured questionnaire was conducted on 120 late school-age children on June, 2010. Results: The results of this study were as follows; Through this, developed program was proved its effectiveness in enhancing knowledge level on nocturnal emission and menstruation in late school-age children(t=14.03, p<.001, t=11.52, p<.001). Conclusion : Accordingly, this program is expected to be an educational program to be used in various educational institutes, communities, and home as well as self-study that allows children themselves to study repeatedly, choosing the contents they want, whenever they hope as an educational program on nocturnal emission and menstruation in school-age children. In addition, it is suggested that various fields of programs should develop in consideration of early sexual maturity.

Purpose: The purpose of the study was to test the effectiveness of an 8 session intervention program to prevent sexually transmitted diseases (STDs) among at-risk prostitutes. Method: An experimental research design was employed. Subjects were 59 prostitutes (29 in the control group and 30 in the experimental group) who agreed to participate in this study. An STD Prevention Framework derived from Cox's Interaction Model of Client Health Behavior guided the overall intervention and the components. The intervention had 8 sessions with STD-prevention strategies and was led by Public Health Nurses. Analysis included change scores, $x^2$-test, and t-test. Result: The results revealed significant increase in feelings and skills of condom use, peer belief on condom use, condom use practice, and satisfaction with service at public health centers (PHC) on STDs knowledge and skills in the experimental group. However, newly contracted STDs were not significant statistically between groups. Conclusion: The 8 session STDs prevention program showed a effect on emotions, skills and' behaviors of condom use even with the limitation of methodological rigors because of subject-specific conditions. In the future, a capacity-building model based on collaborating networks among community-based organizations will be needed to develop in effective STDs prevention.

Little is known about the impact of family caregiving for the demented elderly in Korea. The purpose of this study was to identify the current state of development of family caregiving research for the demented elderly in Korea and to identify correlates of caregiver or health problems and burdens within the socio-political contexts of Korea. A critical review of 17 family caregivers was carried out. The review revealed that various caregiving impacts and correlates of caregiver burden or health problems have been studied in relation to demented elderly family caregiving. Family caregiving for the demented elderly is a very complex phenomenon and various factors were related to caregiver burden, or their emotional and physical health. Findings from studies reviewed have shown inconsistent, inconclusive, and contradictory results. Furthermore, several conceptual and methodological problems were identified in the studies reviewed: restricted conceptualization, unrepresentative study samples, inadequate sample size, inappropriate study design, absence of comparison groups, inappropriate psychometric properties, and uncontrolled confounding factors. More research, as well as directions for further research, is recommended to identify family caregiving the impact of for the demented elderly, and to clarify the factors that explain results.

The corporate restructuring following the economic crisis in Korea has brought about fundamental changes in the structure and practice of employment relations. However the lack of information on processes and consequences of such changes hinder the appropriate policy making on shop-floor industrial relations. Correct assessment of realities an effective policy making require information on human resource management practices and structure of employment relations at the workplace level. This paper critically examines the experiences of workplace-employee integrated surveys carried out in advanced countries including Australia, Canada, and Britain, to extract methodological implications for such survey in Korea. We focus on the backgrounds of the surveys and practical issues involved in multi-level, longitudinal survey design.

Purpose: The purpose of this study was to evaluate the reliability and validity of the clinical judgement rubric on simulation practice with a post-operative rehabilitation case. Methods: Methodological study design was used to evaluate the reliability and validity of the clinical judgement rubric on simulation practice. The participants were 35 students in a college of nursing. Results: There were showed reliability and validity of the clinical judgement rubric on simulation practice with a post-operative rehabilitation case. In terms of internal consistency, the Cronbach's ${\alpha}$ for all columns was .821. Factor analysis showed that planning, intervention and evaluation domains with Eigen values of 69.87% were bound, unlike the original tool where four factors including noticing, interpretation, responding and reflecting domains were bound. Convergent validity was established by the correlation between the total clinical judgement score and critical thinking disposition before and after simulation practice. Discriminative validity was established by the correlation between the total clinical judgement score and simulation effectiveness score. Conclusion: The findings of this study suggested that clinical judgement rubric on simulation practice is reliable. Repeated studies are needed to objectively evaluate the clinical judgement rubric of simulation practice for applying various clinical situations.

Legislation on pharmaceutical reimbursement decision using economic evaluation results was made in Korea in fm, but has yet to be fully implemented. We evaluated the quality of Korean economic evaluation studies of pharmaceuticals to understand gaps between legislation and implementation. From this evaluation, we propose policy options that might strengthen the research Infrastructure In order to support such studies. We reviewed 23 published studies for drugs conducted between 1996 and 2004. Evaluation criteria included methodological characteristics, healthcare system characteristics, population characteristics, and applicability of results. Large variation in study quality was observed, particularly with study design, outcome data, treatment patterns and interpretation. Korean clinical data used was mostly from observational studies of 1-2 hospitals. Foreign data was extracted from clinical trials that did not Include Asian population and their selection criterion was not clarified. With respect to treatment patterns, medical records and hospital bills were used without adjustment regarding area, hospital type, and others. And next frequent situation relied on expert opinion from academic physicians in specialty practice. preference measures, when used, were not elicited from the Korean population. $78.3\%$ of studies did not clarify the funding source. If the Korean economic evaluation policy is to provide meaningful data for decision makers, the quality of cost-effectiveness studies will need to improve dramatically. This may involve access to or creation of better data, more diverse funding, unproved training of researchers and evaluators, and partnerships with technology manufacturers.
