The purpose of this study was the family caring for the patients under home care nursing in the two college hospitals in Busan and Kyungnam Province. Researchers deep-interviewed the participants and asked using the non-constructed questions. 'What did you experience through home care nursing?'. The results are summarized as follows ; First, there were 196 final meaningful statements in the end and 32 constructed meanings, which were classified into 13 themes. These themes were again divided into four categories such as introduction, development, turn and conclusion. In the 'Introduction' three themes were included as follows ; 'feeling their eyes blinded', 'feeling a burden to have such a patient at home', and so on. In the 'conclusion' consisted of four such as 'finding it worthwhile to take care of them at home despite in the suffocated reality', 'pinning hope on the patient', 'retiring the world at first, but later going outdoors and feeling better', and 'realizing the real meaning of family through the difficult situation'. On the basis of this research results, home care nurses have to include the patients' family among home care clients and gradually change the home care nursing into the positive direction by sensitively responding to their requests.

This research is concerned with environment problems related to Munhwa-Maul where Korean government are financially much supporting in developing housing sites and constructing houses. The purposes of this research are to find out the problems and to present the practical guidelines in order to improve an environmental quality of Munhwa-Maul in which will be under construction in the near future. The method for finding out the problems are based upon the most atisfaction and dissatisfaction of residents with opened interview. Both Mueur Munhwa-Maul and Umo Munhwa-Maul are considered for this research because Mueur Munhwa-Maul is characterized with a modern village where is located far from the city while Uo Munhwa-Maul, near the city. Also, these Munhwa-Mauls have been firstly constructed. The interview participants are 34 persons in all. They are confined to Mueur Munhwa-Maul and Umo Munhwa Maul that have been firstly constructed in Kyeongook. According to the interviews, each 60% of both Mueur Munhwa-Maul interview participants and Umo Munhwa-Maul ones have shown the their most positive satisfaction in a new housing and facility. It can be seen from that these figures that housing environment including facility of both Munhwa-Mauls is surely improved and successful. On the other hand, 43.8% of Mueur Munhwa-Maul participants and 14% of Umo Munhwa-Maul ones have particularly shown the most negative satisfaction in a size of housing lot. Also, 15.6% of Mueur Munhwa-Maul interview participant and 44% of Umo Munhwa-Maul ones have stated the most dissatisfaction in a traffic convenience. The reasons showing these differences are likely that 90% of Mueur Munhwa-Maul residents are farmer while 85% of Umo Munhwa-Maul ones are not farmer. With this results the purpose of munhwa-Maul project that government has been supporting and the reality of Umo Munhwa-Maul could be never coincident. Therefore, it can be inferred that housing layout should be reconsiderd to be appropriate for agriculture and that the government should carefully consider the contributions of new housing lot to real farmers. In addition, we can say that Munhwa-Maul project should be firstly accomplished in the district far from the city rather than near the city.

In this paper, we have developed the 6 DOF force display system to be based on the single PC. The system is composed of the force display device, the force reflecting rendering algorithm and the high-speed controller. The previous systems had a problem, that must adopt high performance workstation or 2-PC in order to control the graphics speedily and stably. In this paper, it is possible to improve the problem as to develop its exclusive controller and new rendering algorithm. The proposed new rendering algorithm is based on the Proxy algorithm, which can convert information of the position, the velocity, and the haptic information into the force-data. Especially, as to use the proxy algorithm, we can construct dynamical virtual-environment with the elasticity, the viscosity, the mass, and the friction force. As the result of the experiment, we found that our system has much superior characteristics than some other haptic interfaces, because it can control of 30,000 polygon model constructed virtual object with 1[kHz] haptic interrupt cycle and 20[Hz] graphic interrupt cycle in the single PC based system.

People are increasingly demanding to experience realistic behavior of virtual characters in computer games. In this article, we build a computer model for simulating a bicycle rider's behavior in a virtual riding system. A method to calculate the speed of a bicycle rider is proposed to improve the reality in a virtual riding system. In this method, the property of physical energy is introduced, and the bicycle-riding speed is calculated in real time according to the relationship between the rider's physical energy and bicycle-riding speed. Then based on the analysis of the behavior of a cyclist in a real competition, various behaviors of the virtual rider are designed and a behavior-tree for the virtual bicycle rider is constructed accordingly. On the basis of these, a virtual riding system is developed. The experiments results show that our system can simulate the behavior of a virtual bicycle rider, and thus encourage exercise on a stationary bicycle.

A study on the available power of a wind turbine to be used for wind farm control was performed in this study, To accurately estimate the available power it is important to obtain a suitable wind which represents the three dimensional wind that the wind turbine rotor faces and also used to calculate the power. For this, two different models, the equivalent wind and the wind speed estimator were constructed and used for dynamic simulation using matlab simulink. From the comparison of the simulation result with that from a commercial code based on multi-body dynamics, it was found that using the hub height wind to estimate available power from a turbine results in high frequency components in the power prediction which is, in reality, filtered out by the rotor inertia. It was also found that the wind speed estimator yielded less error than the equivalent wind when compared with the result from the commercial code.

The purpose of this study is to qualitatively investigate how career women form their self-identity in relationship to their parents from the viewpoint of life-span development, and to provide practical information helpful for understanding the change of relationship between parents and adult children and forming desirable parents-daughter relationships by developing the substance theory which suits the socio-cultural context of Korea. In this study, 24 unmarried women who have parents and engage in professional jobs were selected for an in-depth interview. From the findings of this study, 67 concepts, 29 subordinate categories and 13 categories were extracted during the process of open-coding; a research model was then constructed according to the paradigm of the grounded theory. It was found that there are three types: the reality-convinced type, the conflict-compromising type and the self-regulated type who "persistently worry about themselves and try to develop". These results verify the process of career women "worrying about themselves and developing constantly" and its structure by forming their self-identities, adjusting the effects of several contextual factors and using mediatory strategies in the developmental process of self-identity.
