In this paper, we present an abstract object-oriented plat-form model .suitable for the real-time distributed telecommunication system. The proposed platform is constructed upon the extended version of the real-time, distributed operating system, SROS(Scalable Real-time Operating System), that is developed at ETRI and successfully operated in the ATM switching system for several years. The object-oriented software development and maintenance methodology will resolve the current software crisis in the area of telecommunication and switching systems due to the everlasting maintenance about the huge amount of the existing software and the ever increasing needs for the better and new communication services. In general, an object-oriented software platform realizes the object-oriented methodology and possesses many good aspects like high productivity, better reusability, easy maintenance, et at. The platform is also designed to present the distributed multimedia service in addition to real-time event delivery. Recently, we have been implementing a couple of prototype bated on the proposed platform. Reflecting the evaluation results from these prototypes, the final platform specification will be determined.

The objective of our study was to evaluate the dietary intakes and eating habit for seniors utilizing ten different social welfare centers in Seoul, Korea. The total number of subjects of this study was 543(male: 199, female: 344) of 60 years of age or older. The survey was performed through personal interview questionnaires from May 3rd to June 1st 2006. After assigning subjects to four categories based on family type, single, couple, joint family, and other, these categories were compared with the estimated total nutrient intakes and eating habit. Validity was assessed by comparison with 24-hour dietary recalls and dietary variety score(DVS). The results showed that senior in single family type was far lower than that of couple family type in terms of frequency of meal per day and intake of snacks. Dietary variety score represented that a single female with social security beneficiary showed the lowest variety score compared with other family type. The lunch meal provided by social welfare center turned out to be the most nutritious diet and had significant proportion of daily intakes in essential nutrients such as protein, iron, vitamin A, and vitamin C. Taken together, the family type was a significant factor and the accompaniment is another effector on dietary pattern in the elderly. We strongly suggest that the current lunch program in welfare center should be expanded to breakfast meal, and furthermore the small commodity program is also needed to provide the elderly with meal for social communication.

This paper presents a developing procedure of the CAN-based real-time simulator for car body control, aiming at replacing the actual W/H (Wiring Harness) and J/B(Junction Box) couple eventually. The CAN protocol, as one kind of field-bus communication, defines the lowest 2 layers of the ISO/OSI standard, namely, the physical layer(PL) and the data link layer(DLL), for which the CSMA/NBA protocol is generally adopted. For CPU, two PIC18Fxx8x's are used because of their built-in integration of CAN controller, large internal FLASH memory (48K or 64K), and their costs. To control J/B's and actuators, 2 controller boards are separately implemented, between which CAN lines communicate through CAN transceivers MCP255. A power motor for washing windshield, 1 door lock motor, and 6 blink lamps are chosen for actuators of the simulator for the first stage. For the software architecture, a polling method is used for the fast global response time despite its slow individual response time. To improve the individual response time and to escape from some eventual trapped-function loops, High/Low ports of the CPU are simply used, which increases the stability of the actuator modules. The experimental test shows generally satisfactory results in normal transmitting / receiving function and message trace function. This simulator based on CAN shows a promising usefulness of lighter, more reliable and intelligent distributed body control approach than the conventional W/H and J/B couple. Another advantage of this approach lies in the distributed control itself, which gives better performance in hard real-time computing than centralized one, and in the ability of integrating different modules through CAN.

The aim of this research is to verify the assumption that the husband-to-wife violence lies upon a continuum of severity and to study how the premarital violence experience of husbands, along with their psychological characteristics and various marital interactions, can be the cause of husbands' violence against their wives. At the same time, the research aims at constructing a causal model of the husband-to-wife violence. For the purpose, this research surveyed 242 husbands residing in Pusan and another 50 husbands as violent assaulters in major cities of Korea. The following is a summary of the results of this research. First, the research can verify the two assumptions that “the group which has once inflicted a severe form of violence can easily inflict minor violences” and that “the factors related to violence play a far greater role in severe violences than in weaker violences.” As a result, it may be concluded that the study of a regular household violence can be based on the continuum of violence assumption. Secondly, In the husbands' experience of violence, dating violence and their experienced childhood abuse from their parents, in their psychological characteristics, temper control ability and their patriarchal sex role attitude, and finally in marital interactions, marital conflicts and distractor of communication played great role in their influence on the husband-to-wife violence. Thirdly, as the various factors which contribute to the violence against the wife have cause-and-effect rule, we shall be able to make a model which can be conceptualized.

The major purpose of this study was to develop with priority given to the discourse on the correlation between interpersonal resources and home management behavior for family life satisfaction. So, this study was to identify the perception of equity in marital life, through which dynamic aspects is measured with family resource. Some of the major findings are as follows : The perception of equity in marital life show a significant difference by the state of employment and the degree of communication in couple. Housewives'home management behavior show a significant difference by the perception of equity in marital life. It appears that intra system dynamics elements explain housewives'home management behavior. From the Regression Analysis, the Model was found to be highly significant, accounting for 63% of the variances. Especially, housewives'family life satisfaction is influenced by the perception of daily life equity capable of evaluating each of a married couples'contribution and reward for family life lather than perception of psychological-emotional equity.

In this paper, a mercury-free flat discharge lamp with opposite electrode structure, a couple of phosphor layer and discharge vessel has been studied for LCD back-lighting. When the drive voltage conditions were set properly, a uniform discharge generates over entires emitting surface. The firing voltage was increased with increasing the discharge gas pressure. It was considered that this tendency was resulted from the decrease of mean free paths due to the increase of discharge gas pressure. The maximum luminance of 2700[cd/m2] was obtained in the green emitting FFL.
