  • Since the first proposition of IEC61850 object model at 1993, many questions about making a seamless model have been issued. the reason which they have worry about is that the functions of the equipment are supposed to be changed properly and new equipment and scheme are need to be introduced according to user's application. To handle those issues, TC57 which is a IEC committee for power control and communication has continuously updated the object model. Nowadays along with the new object model involving power quality, distribution resource and wind power, the committee has a plan to announce the revision of IEC61850-7-4. In the study, authors will present the prediction and diagnosis object models for transformer. Transformer models for protection and control have already been dealt with in the international standard but the models for prediction and diagnosis have never mentioned until now. Designing the prediction and diagnosis functions with the existing IEC61850-7-4, it'll be shown what is a proper object model for prediction and diagnosis.

  • Pregnant women need to be supported by their husbands and other family members. But little is known about the factors that contribute to perceived support in pregnant women. So this study is designed to identify the factors contributing to perceived support in pregnant women. The subjects for this study were 19 women who had had vaginal deliveries and 11 who had had cesarean sections in one hospital affiliated with a university. Data were collected during July and August 1992 through interview which lasted 20~30 minutes and used open ended questions. Each woman was interviewed once about their pregnancy experience. The data were analyzed by Van Kaam’s phenomenological analysis method and categorized accord-ing to similarity of content. Results of this study are as follows. 1) Mothers felt physically supported by having help with their activities from their husbands or other family members. Psychological stress was relieved by not having to worry about and / or giving a birth to a baby boy ; getting special attention : and hearing encouraging words. 2) Mothers felt not supported when indifference was shown by her husband and / or relatives ; when forced to do an unusual household activities ; or on hearing words stressing her responsibilities. Suggestion for further study are as follows. It is necessary to see if or not the contents of an educational program would increase the perceived support of pregnant women. This could be done by carrying out an experimental research project.

  • This paper presented a method constructing the ITSoC(Information Technology System-on-Chip). In order to implement the ITSoC, designers are increasing relying on reuse of intellectual property(IP) blocks. Since IP blocks are pre-designed and pre-verified, the designer can concentrate on the complete system without having to worry about the correctness or performance of the individual components. Also, embedded core in an ITSoC access mechanisms are required to test them at the system level. That is the goal, in theory. In practice, assembling an ITSoC using IP blocks is still an error-prone, labor-intensive and time-consuming process. This paper discuss the main challenge in ITSoC designs using IP blocks and elaborates on the methodology and tools being put in place for addressing the problem. It explains ITSoC architecture and gives algorithmic details on the high-level tools being developed for ITSoC design.

  • Purpose: This study attempted to describe the essential structure of male students' experience as nursing majors. Method: The data were collected through the in-depth interviews of seven male students majoring in nursing. The analysis of data were made using phenomenological analytic method suggested by Colaizzi(1978). Result: In this study, five essential themes emerged. They are: $\ulcorner$Strong initial -though subsequently declining- hesitation over choice of major$\lrcorner$, $\ulcorner$Challenging, ongoing effort to survive in an environment of new and unaccustomed experiences and relationships$\lrcorner$, $\ulcorner$Recurring sense of reassurance and relief upon occasions of unexpected success$\lrcorner$, $\ulcorner$Growing internalization and acceptance of their role as nursing students or as future nurses$\lrcorner$, $\ulcorner$Ambivalent feelings resulting from the contradiction between their vision concerning their future as nurses and their worry concerning their future as male nurses$\lrcorner$Conclusion: With an increasing number of male students majoring in nursing, this study will prove helpful not only in understanding male students' experience while majoring in nursing but also in describing their needs for systemic and emotional support.

  • This study examined how caregiving experiences of spouses and adult children were different to each other in terms of caregiver characteristics, the impairment level of the elderly, caregiving time, caregiver burden, the effects of long-term care services, etc. Data were collected from 321 spouses and 324 adult children who cared for the functionally and/or cognitively impaired elderly using long-term care services. The main results are as follows. (1) Caregiver characteristics differed significantly between spouses and adult children. (2) Adult children cared for the more severely impaired elderly in terms of IADL, cognitive impairment, and behavior problems while spouses spent more time helping in ADL activities. (3) Spouse caregivers experienced greater overall burden, worry and strain, and financial burden compared to adult child caregivers. (4) Long-term care services were effective in reducing caregiver burden and improving family relations. Additionally, relations between adult child caregivers and the elderly was more improved than relations between spouse caregivers and the elderly after using long-term care services. Based on these findings, the differential experiences between spouse caregivers and adult child caregivers were discussed.

  • The flutter derivatives of bridge decks can be efficiently identified using the experimentally and/or numerically coupled forced vibration method. This paper addresses the issue of inherent requirement for adopting different frequencies of three modes in this method. The aerostatic force components and the inertia of force and moment are mathematically proved to exert no influence on identification results if the signal length (t) is integer (n=1,2,3...) times of the least common multiple (T) of three modal periods. It is one important contribution to flutter derivatives identification theory and engineering practice in this study. Therefore, it is unnecessary to worry about the determination accuracy of aerostatic force and inertia of force and moment. The influences of signal length, amplitude, and frequency ratio on flutter derivative are thoroughly investigated using a bridge example. If the signal length t is too short, the extraction results may be completely wrong, and particular attention should be paid to this issue. The signal length t=nT ($n{\geq}5$) is strongly recommended for improving parameter identification accuracy. The proposed viewpoints and conclusions are of great significance for better understanding the essences of flutter derivative identification through coupled forced vibration method.

  • Purpose: The purpose of the study was to identify and describe illness experiences of men with myocardial infarction. Methods: Data were collected through individual in-depth interviews with 10 male patients. Analysis was done using phenomenological analysis. Results: Five theme clusters including 11 themes emerged. 1) "Unexpected grave disease instantly dividing life and death" describes the great ignorance of symptoms and experience as a survivor narrowly escaping death. 2) "A disease still not considered a disease" illustrates the paradoxical and confusing situation between low level of awareness of the severity of the disease and high level of reflection on their unhealthy lifestyles. 3) "Fighting against me for health" illustrates their resolution and action to maintain health while experiencing helplessness. 4) "Relationships in a no-win situation" contains defensive posture due to social stigma and the dilemma of family breadwinners. And 5) "Introspection of past and future life" describes positive turnings in life through enlightenment in addition to remorseful feeling about the past and persistent worry of death. Conclusion: Health professionals need to support men with myocardial infarction by providing family-oriented and empowerment-based self-management interventions to lead to success in their illness journey and to improve their quality of life.
