In this paper, we establish the conceptes of compactifications of a L-fuzzy topological space and a order relation in these compactifications. This order is a preorder. The existemce problem and the uniqueness problem of the largest compactifications are closely related to the mapping extension problem. We give out the largest compactifications and show the non-uniqueness of the largest compactifications in the preorder for a kind of spaces. Moreover, under some natural assumptions of separation axioms, we prove that the preorder is just a partial order, thus it ensures the uniqueness of the largest compactification. In addition. the related discussion involves the special properties of fuzzy product space, the latter seems to be independent interesting.

This study proposes the analysis method in sentence semantics that can be automatically identified and processed as appropriate items in the system according to the composition of the sentences contained in the data corresponding to the logical semantic structure metadata of the research papers. In order to achieve the purpose, the structure of sentences corresponding to 'Research Objectives' and 'Research Outcomes' among the semantic structure metadata was analyzed based on the number of words, the link word types, the role of many-appeared words in sentences, and the end types of a word. As a result of this study, the number of words in the sentences was 38 in 'Research Objectives' and 212 in 'Research Outcomes'. The link word types in 'Research Objectives' were occurred in the order such as Causality, Sequence, Equivalence, In-other-word/Summary relation, and the link word types in 'Research Outcomes' were appeared in the order such as Causality, Equivalence, Sequence, In-other-word/Summary relation. Analysis target words like '역할(Role)', '요인(Factor)' and '관계(Relation)' played a similar role in both purpose and result part, but the role of '연구(Study)' was little different. Finally, the verb endings in sentences were appeared many times such as '~고자', '~였다' in 'Research Objectives', and '~었다', '~있다', '~였다' in 'Research Outcomes'. This study is significant as a fundamental research that can be utilized to automatically identify and input the metadata element reflecting the common logical semantics of research papers in order to support researchers' scholarly sensemaking.

The purpose of this study is to investigate and analyze the actual state of teaching and learning methods which are applied to the vocation inquiry section-related subjects of the College Scholastic Ability Test(CSAT) by the teachers who teach specialized subjects of vocational high schools. In order for us to get the background and feature of establishment in the area of vocation inquiry section of the CSAT, previous studies and literature was analyzed and sample survey on the 600 teachers who teach the vocation inquiry section-related subjects was made. The result of this survey is as shown below; First, the teachers who are in charge of vocation inquiry section-related subjects understand that theory and practice is in the ratio 60.76:39.24 and ratio of theory is higher than that of practice. Second, teaching and learning method which is the most relevant to the vocation inquiry section is in the order of lecture(83.9%), experiment & practice(50.4%), computerized learning(41.1%). Third, teaching and learning method which is the most used by the teachers who are in charge of vocation inquiry section-related subjects is in the order of lecture(85.8%), computerized learning(50.1%), experiment and practice(44.4%). Forth, the most desirable teaching and learning method which the teachers who are in charge of vocation inquiry section for this subject believe is in the order of lecture(62.7%) experience & practice(47.7%), computerized learning(44.4%). In light of this result, even though there were not so much difference among the teaching-learning methods which are the most consistent with the contents of the subject in relation to the vocation inquiry section, the most used teaching-learning method by the teachers who teach vocation inquiry section-related subjects and the most desirable teaching-learning method which the teachers who are in charge of vocation inquiry section believe, the most used teaching-learning method by the teachers who are in charge of the vocation inquiry section is lecture. Therefore, it is necessary for us to reinforce the contents in relation to the practice & experiment so that the experience and application can be accumulated and improved through practice which is the specialty of the course of the study in the vocational high school and various teaching and learning method should be developed in consideration of contents of the subject, capability & quality of the learners and status of a classroom.

In this paper, we propose a criteria which can be applied to classify conventional color feature based Content Based Image Retrieval (CBIR) methods with its application areas, and a new image retrieval method which can represent sufficient spatial information in the image and is powerful in invariant searching to translation, rotation and enlargement transform. As the conventional color feature based CBIR methods can not sufficiently include the spatial information in the image, in general, they have drawbacks, which are weak to the translation or rotation, enlargement transform. To solve it, they have represented the spatial information by partitioning the image. Retrieval efficiency, however, is decreased rapidly as increasing the number of the feature vectors. We classify conventional methods to ones using 1st order relations and ones using 2nd order relations as their color object relation, and propose a new method using 3rd order relation of color objects which is good for the translation, rotation and enlargement transform. It makes quantized 24 buckets and selects 3 high scored histogram buckets and calculates 3 mean positions of pixels in 3 buckets and 3 angles. Then, it uses them as feature vectors of a given image. Experiments show that the proposed method is especially good at enlarged images and effective for its small calculation.

This study examined the influence of university students' stress in their daily lives on game addiction, and investigated whether the human relation skills has a moderating effect on their daily life stress. For this study, surveys of 222 university students were collected and analyzed with SPSS 18.0 program. The results of this study are as follows: First, the participants displayed lower human relation skills as the level of stress from the studies increased. In contrast, the participants displayed higher human relation skills as the level of stress from future plans and family relations increased. Second, as the level of game addiction increased, human relation skills were found to be lower. Third, the university students' stress from daily lives had a static effect on game addiction. The participants displayed tendency of game addiction as they had high levels of stress from their studies, financial issues, future plans, values, family relations, and human relations with people apart from their family. Among the listed factors of stress, the stress from the studies most strongly influenced the participants to be addicted to games. Fourth, among the sub-factors of stress in the university students, issues in future plans and family relations significantly control the game addiction. Studies on this area has been insufficient. From the study, it is found that in order to prevent university students to be addicted to games, they must cope well with their stress. Furthermore, this study carries its significance in finding the results that human relation skills contribute as a part of dealing with stress.

This study was done for the purpose of analyzing the job-satisfaction and its depressive factors in human relation of operating room nurses of university hospital. Therfore, it makes an offer the basic data to help the resolution and prevention of the problems in operating room nurses. Furthermore, this study was conducted in order to find out some kinds of scientific data for the better control of depressive factors of job-satisfaction expressed by the operating room nurses. The structred questionaire reports of 246 operating room nurses who were employed in 5 different university hospitals which have over 1, 000 beds located in Seoul, Korea were used, which wer collected from August 24th to August 30th of 1992. The author visited supervisors of operating room in each university hospital and explained the aim of this study. The most of them(90.0%) answered to the questionaires. Analysis of the collected data were done by mean, standard deviation, percentage, t-test, F-test, Q-test, correlation analysis, one-way ANOVA.and stepwise multiple regression analysis. Major findings of this study were as follows: 1. The job of the operating room nurses were remarkably related with the satisfaction in human relation, which was defined as the behavioral job with thoughtful action rather than with mechanical action. However, the degree of satisfaction in human relation with personnel in other departments was found to be the lowest and its the main depressive factors were appeared due to the absence of interaction and uncooperative attitudes. Therefore, it was required that the members of other job need more cooperative attitude to the actual works in the operating room nurses. 2. The depressive factors in the satisfaction degree of human relation with offical seniors wer significantly related with their irresponsibility and partialness. Moreover, the job attitude of the operating room nurses is abundantly required to be improved, 3. The depressive factors in the satisfaction of human relation with medical doctors were significantly related with their insincerity and the class-consciousness. It is clearly suggested that the medical doctors do more cooperative behaviors for the jobs of the operating room without the suggested that the medical doctors do more cooperative behaviors for the jobs of the operating room without the superiority feeling of class-consciousness. 4. There was a significantly positive association between the satisfaction degree of human relation of the nurses with the following charateristics. (1) The registered nurses which had a tendency to be satisfied about the registered nurses' job. (2) The registered nurses which had a tendency to be a technique-aptitued in the motivation of the registered nurses'job. (3) The registered nurses which had a tendency to be satisfied about the total hospital working carrier and the aspects of old ages. Finally, these findings indicated that the operating room nurses should require the professional education courses associated with a high-development techniques and setisfaction in their jobs.

The wedge type rail clamp compresses the rails with small clamping force at first, and with large clamping force when the wind speed increases because of the wedge working. If the supporter is not installed in the rail clamp with V-type wedge when the wind speed increases more and more, the structure will occur overload which leads the structure to fracture. But in the clamp with U-type wedge the supporter is not necessary because the tangential angle of the wedge increases as the sliding distance increases. The proper shape of U-type wedge is determined by the initial clamping force and the tangential angle of the wedge. Accordingly we, first carry out the finite element analysis in order to analyze the relation between the sliding distance and the wedge angle. Next we suggest the proper shape of U-type wedge as analyze the relation between the radius of curvature and the sliding distance.

This paper attempts to analyze Korean proverbs with pap 'rice' which plays an important role in the Korean community. I examine to analyze the data under the various frameworks: Grice, lakoff and Langacker. Proverbs use the contrast in order to focus the speaker's intention and to get the convince from hearers. I limited to analyze coordinate sentences since these distinctively show the contrast and the relation. In terms of the contrast and the relation, the semantic interpretations of pap can be easily taken. These semantic interpretations are classified under the Lakoff's metaphors.
