I analyzed the relationships among motives, strategies, and performances of the university-initiated R&D activities in the Information Technology Research Center(ITRC) Projects. I suggested a research model and 3 hypothesis about them through analysis of a lot of literatures. And I also made an empirical test on the hypothesis through statistical methods. The data which were used in this analysis were gathered through a questionnaire survey to the head of R&D projects in the ITRCs. I would make several useful suggestions to the head of university's ITRCs and the policy makers. Firstly, the type of university's R&D strategy were influenced from several motives such as technology development and acquisition, co-utilizations of research facilities, and utilization and rearing of the expertise. Secondly, to select an optimal type of R&D strategy, the university should considered the efficient methods which were related to forecasting market size of new product and new technology, and to using the useful information on technology development, and to securing the expertise. Thirdly, the researcher and manager of ITRCs had to recognize the correct forecast of future market size of new product and new technology and a useful information about technology development, as the most important factors in improving performances of R&D projects. Lastly, They had to make an effort of getting the efficient methods to secure the expertise, research facilities, and rational compensation system.

Recently, considerable effort has been made to maintain a pleasant and safe indoor environment in buildings. For this, the use of a ventilation system attached to a range hood in kitchens has prevailed. Accordingly, diversiform designs for range hoods have been used. Press molding is normally used for range hood construction for several reasons. On the other hand, its economic efficiency is low in the case of a small production work. Considerable research has been carried out to solve this problem and it is believed that it is useful to use the change core method to develop molds. This study designed the core of a mold using the change core method and a total of four processes were used in its manufacture. As a result, the press molds, which are needed for shorter production runs and whose form is changeable, were developed. In addition, after the measurements in three-dimensions, the specimen passed a test within a tolerance of ${\pm}2.00mm$.

The primary purpose of this research is to develop and test a model that explains the process of how In-store experiences (physical environmental quality, personal interaction, product experience) through perceived risks and brand attitude influence purchase intention. Perceived risks and brand attitude are proposed as mediators that make a significant impact on purchase intention. Through structural equation modeling using 235 consumers who visited the experience store in IT Industry, we find that In-store experiences influence perceived risks, brand attitude and then enhance purchase intention. Thus, IT companies should make every effort to create In-store value for visited consumers. Based on these results, managerial implications for experience store operation and marketing strategy are discussed. Finally, limitation for this research and further research issues are suggested.

Issues related to the elderly have been recognized in Korea and nursing schalors have tried to study these issues. It is hard to say which the direction we, are going or have to go, since there has been little systemic effort to establish gerontological nursing field yet. Therefore, it is necessary to find out the trend and the guidelines of gerontolotical nursing studies for the future. Dissertation and published articles related to the elderly in the nursing field from 1991 to the Feburary of 1997 were are reviewed. Total 127 studies were analysed in terms of concept, design/methodology, and results, and the nature and issues of the gerontologic nursing studies in Korea were explored. The results are as follows : 1. There was no clear chronological definition of the elderly. 2. The most popular research design was an exploratory/descriptive study. 3. The major concepts studied were physical and mental health. 4. Among those studies using instruments which were developed and modified and/or translated by researchers, the reliability and validity were rarely reported. 5. Theory based studies were rare. We suggest the following issues for future studies : 1. The chronological and other criteria related to the defition of elderly is needed. 2. Physiopsychosocial characteristics of Korean elderly and their mangements in terms of intervention studies need to be conducted more systemically. 3. Social issues from the change of types and functions of family such as single elderly family need to be studied. 4. Participation in and collaborate with other disciplins are needed. 5. Development and test of instruments to measure phenomena or concepts is needed. 6. Macroscopic approach such as policy also needed. 7. Theory based studies are needed.

From of old, labor has been accompanied by pain and much effort has been mode to eliminate or diminish the amounts of pain during labor. Little concern has yet been given to the subjective meaning of pain in labor. Recently, rates of cesarean section in Korea and in some other nations have increased rapidly and some investigators are reporting negative reactions such as anger, disappointment and feeling of loss due to lack of control over labor and its pain. These findings are thought to suggest that control of labor and its pain gives some meaning to the laboring woman. Thus the investigators sought to discover the meaning of pain during labor for Korean women. Specific objectives of this study were to explore the meaning of pain in labor to the mothers, their reactions to the experience of labor add their preference for delivery method. The subjects of this study were 95 mothers who delivered their babies in hospital from September 989 to May 1990 : 45 gave birth by vaginal delivery, and 50 by cesarean section. Data were gathered through direct interviews by the investigators, and questions were focused on five areas i.e. mothers' feelings about delivery and their babies, their feelings about of having more children, the most difficult aspect about this labor and delivery, and what they thought the differences were between vaginal delivery and cesarean section. After interview, mothers' answers were summarized, and classified according to the degree of positive or negative attitude. To ascertain the difference in meaning of labor pains and reaction to delivery experience between mothers delivered vaginally and by cesarean section a Median test was done using an SAS. Results were as follows. 1. More mothers who had delivered vaginally realized that they “have became a mother” than those who had a cesarean section(X$^2$＝8.409, df＝3, p＝0.038). 2. Immediate reaction to their delivery experience was more positive for mothers who had a cesarean section. 3. These Korean mothers expressed preference for vaginal delivery. Suggestions for further research on the meaning for mothers of their experience of labor, and on the meaning of pain for mothers who have a cesarean section were made.

Most of the APP market today, it is biased in the field of games and entertainment. In contrast, market-share of the educational APP is very low. This phenomenon is due to two major problems. The first is a decrease in the reuse because of the test of simple pattern. The second is difficult to consider user-level range that was learned previously. In this case it is necessary for students to do additional effort. This paper, propose an educational intelligent educational APP to solve the problems described above and shows implementation results. This system analyzes the stored results that have been saved to determine the area of vulnerability. Time-based Re-validation module helps long-term memory of student. The proposed system in this way directly supports self-directed learning. Therefore, the students can be able to relearn weak area autonomously. It results in improved academic achievement.

Lately development of network around Internet expands range of data traffic to multimedia information, and so for the guarantee of multimedia services end-to-end QoS(Quality of Service) must service because comparing with existing Internet service can not support For satisfying those QoS requirements, network have to guarantee not only network on parameter, such as delay, jitter, throughput but also system resources like CPU utilization, memory usage. Therefore it is urgent to develop QoS based middleware to distribute multimedia data and maximize network utilization in the limited resource environment. And it must be necessary of network to provide end-to-end QoS(Quality of Service) for multimedia applications. Multimedia applications want that QoS which satisfy their own service properties be guaranteed Then, We must analyze those necessary QoS requirements md define QoS parameter which specify as two viewpoint, user's and network's perspective. Therefore network provider supplying network for usual user and university, enterprise must want to find about their own network performance and problem. It is essential for network manager to want to use a tool like this. On the basis of technique about QoS test-bed in the AIM network, We studied on the method of QoS measurement and management about end-to-end connection in the Internet. We measured network status about end-to-end connection and analyze the result of performance.

This paper discusses the development of an up-to-date computerized CPT (Cone Penetration Test) based soil engineering classification system to provide geotechnical engineers with a handy tool for their daily design activities. Five CPT soil engineering classification systems are incorporated in this effort. They include the probabilistic region estimation and fuzzy classification methods, both developed by Zhang and Tumay, the Schmertmann, the Douglas and Olsen, and the Robertson et al. methods. In the probabilistic region estimation method, a conformal transformation is used to determine the soil classification index, U, from CPT cone tip resistance and friction ratio. A statistical correlation is established between U and the compositional soil type given by the Unified Soil Classification System (USCS). The soil classification index, U, provides a soil profile over depth with the probability of belonging to different soil types, which more realistically and continuously reflects the in-situ soil characterization, which includes the spatial variation of soil types. The CPT fuzzy classification on the other hand emphasizes the certainty of soil behavior. The advantage of combining these two classification methods is realized through implementing them into visual basic software with three other CPT soil classification methods for friendly use by geotechnical engineers. Three sites in Louisiana were selected for this study. For each site, CPT tests and the corresponding soil boring results were correlated. The soil classification results obtained using the probabilistic region estimation and fuzzy classification methods are cross-correlated with conventional soil classification from borings logs and three other established CPT soil classification methods.

In an effort to identify predictors of job performance, research studies in social work administration has been so far on the individual practitioners' levels of knowledge and skills, which could be used in a workplace. As the theoretical concept of organizational environment was fully introduced into social work administration research, however, studies on practitioners' job performance began to have interest in the team or the organizational level variables as well as individual level variables. Along the course of this tendency, this study attempted to test the effect of individual, team, and organizational level variables on the job performance of human service workers. The individual level variables consisted of knowledge, skills, job satisfaction, personality, and counter-productive work behaviors of workers. The team or the organizational level variables included situational constraint, organizational justice, job characteristics, government-dependency, and inter-organizational cooperation. Multi-level complex survey data collected by cluster sampling method from 314 practitioners in 23 organizations were analyzed using Hierarchial Linear Model. Results showed that both task and contextual performance were affected by individual, team, and organizational level variables in various ways.
