A standard fire extinguishing tester, with which we could conduct the fire extinguishing ability rating of a water-based fire extinguishing agent such as water and loaded stream, has been developed in this work. It could help us enhancing the efficiency and reliability of the fire extinguishing test of loaded streams, and at last increasing the productivity of fire protection related firms. Furthermore, our country could take the lead in making a new standard for the fire extinguishing test of loaded streams. As a result, it is expected that loaded streams could be improved by using it. In addition the standard fire extinguishing tester could be made moderately in our industry, and supplied at home and worldwide.

The predictions derived from Sternberg's triangular theory of love were tested in order to explain the love relationships in marriage among Korean people. We were first interested in whether the subjective love experiences of respondents could be characterized by three components: intimacy passion and commitment we then attempted to examine the time course of each component as the marital relationships continued. 16897 married men and women were asked to complete the questionnaire including the love scale developed by researchers based on Sernberg's and other researchers' work. The results are as follows: First the love experienced by Korean men and women in their marriage can be classified by 3 dimensions: intimacy passion and commitment. Secon intimacy is the most powerful indicator of love in marital rlationships follows bgy passion and commitment. Third each of the 3 dimensions of marital love showed a U-shaped pattern as the marriage continued. Fourth commitment was more table than the other 2 dimensions throughout the marriage. The resultso f the study showed that Sternberg's triangular theory of love is useful to explain the marital love among Korean people.

PAC has been in the demand day ;lner day and in the tn'nd on the bc,ing the necessJty of the n'sent wf',lther warming phenomenon This study is the case study nf the products development and design process of PAC which has bpcn llrivcn and developed by Gold Star Co. ,Ltd. Which .is the firm for home electric appliances representing Korea. This studies for the development and the design of the products by the firm thus emphasizing the visulizing it based on this study. For example as they being the goods for the summer season I have tried to know the physical quakity and the characters of koreans by the weather conditions and estimated the demand by setting up the target customers of the PAC as the customers' environment. And I analyzed the acts in the living room in the apartments as the living envinorment which has the direct relation with PAC and also became a help to the moulding work of PAC by analyzing the complete interior image in the living room. In the practical moulding work the Design concept was classified into the envinorment of customer, living and products to drive as the below. Firstly - New shape (Round slim) has been realized which leads the minimizing the moulding space and visul sense of opening as its being spacious. The 2nd - the high class sense of the products which are harmonious with the atmosphere of the living room by making it interiorized has been visible. The 3rd - The shape stimulating the sensitivity of the users and surface treatment are emphasized by making it be touched. The 4th - During inviting use of technology image which appears in the electronics products are attemptedby making it be high quality.king it be high quality.

Recently, wireless multi-networking technology has been studied for supporting multi-interface in mobile node. As the related work, in the IETF NetExt WG, the extension of Proxy Mobile IPv6 protocol for supporting flow mobility is actively on going in discussion. PMIPv6 protocol supports simultaneous access through the multi-interface in a mobile node and inter-technology handover between multiple interfaces. However, this protocol can not support flow mobility. Thus, in this paper, when a mobile node connects to PMIPv6 domain through multi-interface, as a way to support flow mobility, the design of logical interface and Home Network Prefix change scheme based on logical interface are proposed, We show that the proposed scheme can perform flow mobility service without end-to-end disconnection in PMIPv6 domain.

It is a general trend in the world that female workers are drastically increasing due to the facts that highly developed capitalism requires women's job, women are inspired to work, housewives can shorten their working hours for house-keeping and save their energy from their routine works, educational expenses of their children become larger, large among of modities has stimulated purchasing desire. Since the International Treaty on Prohibition of Female's Night Labor was agreed at the Bern's Conference in 1906, the International Labor Organization (I.L.O.) established after the World War II, has adopted innumerable international labor treaties. According to the laws of the advanced countries, the first priority of their protection has been placed on juvenile and female workers. The legal protection of female workers and equal treatments such as wage and promotion between men and women have become important world problems. In this thesis, the great principle of the Labor Standard Law, protection regarding working house, risk and harm in performance of jobs, protection of mother-workers, protection of women workers in advanced countries and the present status of welfare facilities for women workers in our country will be studied. The most important points this thesis has placed stress and appealed, are as follows : 1. The scope and variety of women workers' jobs should be broadened. 2. Opportunity for promotion should be guaranteed for women workers based upon the ability and capacity of individual woman worker. 3. Equal wage principle between men and women workers, should be established based upon the idea that men and women should be equal. 4. The age limit or marriage limit of employment applied only to female workers, should be abrogated. 5. The ability of middle and old aged women workers should be developed and utilized to the maximum extent. 6. Welfare facilities for women workers, should be urgently secured and guaranteed.

In this paper an imrpoved Signal-to-Interference ratio(SIR)-based call admission control(CAC) algorithm for DS-CDMA cellular system is proposed and its performance is analyzed. This algorithm uses Residual-Capacity defined asthe additional number of initial calls that a base station can accept such that system-wide outage probability will guaranteed to remain below a certain level. the residual capcity at each cell is calculated according to the reverse-link SIR measured not only at the home cell but also the adjacent cells. Then the adjacent cell interference-coupling coefficient .betha. is used. In this work we propose an improved algorithm that .betha. varies according to the traffic load of the home cell. The influence of traffic condition on system performance, namely blocking probability and outage probability, is then examined via simulation. The performance of the improved algorithm is evaluated both under homogeneous and hot spot traffic loads. The results show that the improved algorithm outperforms conventional algorithms under all load values. Under over-load situation, especially, the improved algorithm gives almost constant outage performance the QoS(quality of service) can be guranted.

Video-based human-activity recognition has become increasingly popular due to the prominent corresponding applications in a variety of fields such as computer vision, image processing, smart-home healthcare, and human-computer interactions. The essential goals of a video-based activity-recognition system include the provision of behavior-based information to enable functionality that proactively assists a person with his/her tasks. The target of this work is the development of a novel approach for human-activity recognition, whereby human-body-joint features that are extracted from depth videos are used. From silhouette images taken at every depth, the direction and magnitude features are first obtained from each connected body-joint pair so that they can be augmented later with motion direction, as well as with the magnitude features of each joint in the next frame. A generalized discriminant analysis (GDA) is applied to make the spatiotemporal features more robust, followed by the feeding of the time-sequence features into a Hidden Markov Model (HMM) for the training of each activity. Lastly, all of the trained-activity HMMs are used for depth-video activity recognition.
