This study was conducted with 512 students in 4 primary schools located at the inner and the outskirt of K city, Northern Kyungsang Province from November 6, 2001 to November 27, 2001(during 3 weeks). This study was a research about the difference of a bullying degree and tendency of both teasing and teased students. The purpose of the study was to help nursing teachers in charge of student consultation and treatment. The findings are as follows: First, for to whom students confess their worries, students in lower grade talked to their parents while students in higher grade talked to their close friends. The higher grader, the higher rate in solving their problems by themselves. For how many students are teased by their peers in groups, 52.0％ students answered 1 or 2 students in a class. For the reasons of bully, 37.0％ higher graders answered, very selfish and putting on airs after 29.6％ lower graders answered, ugly and bad at speaking. Second, for perception of peer relation, 81.3％ students participating in the study answered, very important. For a question whether students satisfy present relation with their friends by gender, 53.7％ boys were satisfied while 34.6％ girls were satisfied. Third, for difference in bullying by gender, boys mainly teased others by using words and physical power(p<0.000) while girls estranged others. When it goes to teased students, it was the case: boys were bullied physically(p<0.000) and linguistically while girls were hurt by estrangement. Having nothing direct to do with school achievement, nursing teacher should make good use of such an advantage that students tend to easily confess their worries to them and take care of psychological aspects of students in treatment. Furthermore, it needs to include contents of bully in the regular heath care education.

In this study, the dielectric breakdown of epoxy composites used for transformers was experimented and then its data were simulated by Weibull distribution probability. The dielectric breakdown characteristics origin in epoxy composites were examined and various effects of dielectric breakdown on epoxy composites were also discussed. As a result, first of all, speaking of dielectric breakdown properties, the more hardener increased the stronger breakdown strength at low temperature because of cross-linked density by the virtue of ester radical. And the breakdown strength of specimens with filler was lower than it of non-filler specimens because it is believed that the adding filler forms interface and charge is accumulated in it, therefore the molecular motility is raised, the electric field is concentrated, and the acceleration of electron and the growth of electron avalanche are early accomplished. In the case of filled specimens with treating silane, the breakdown strength become much higher since this suggests that silane coupling agent improves interfacial combination and relaxs electric field concentration. Finally, from the analysis of weibull distribution, it was confirmed that as the allowed breakdown probability was given by 0.1%, the applied field value needed to be under 21.5㎹/cm.

In this paper we propose the QAC-MAC that supports Quality of Service(QoS) and saves energy resources of the sensor node, and hence prolonging the lifetime of the sensor network with multiple sink nodes. Generally, the nodes nearest to the sink node often experience heavy congestion since all data is forwarded toward the sink through those nodes. So this critically effects on the delay-constraint data traffics. QAC-MAC uses a hybrid mechanism that adapts scheduled scheme for medium access and scheduling and unscheduled scheme based on TDMA for no data collision transmission. Generally speaking, characteristics of the real-time traffic with higher priority tends to be bursty and has same destination. QAC-MAC adapts cross-layer concept to rearrange the data transmission order in each sensor node's queue, saves energy consumption by allowing few nodes in data transmission, and prolongs the network lifetime.

Louis 1. Kahn was a wise architect who learned from history. He developed his own unique architecture by combining his creative sense with design principles and vocabularies that can be found in historical architecture. When restricting a space, he surrounded the space with thick walls as it had been done in historical buildings. The interior space encompassed by this method became a center-oriented and stable space. The objective of this study is to find the characteristics of Kahn's interior spaces by analyzing his projects in terms of space, form, daylight and materials. For this purpose, five works that are considered to have significance from the aspect of interior design were selected and analyzed. The characteristics realized through this study are as follows. A) Spatial features: 1) Generally speaking, each required space has been arranged symmetrically. 2) Being clearly defined as the main space, the subsidiary space, or the service space, each space also was placed very functionally. 3) The space encompassed by thick walls became a center-oriented, stable space. And in most case, it was characterized as a dark space. B) Formative features: 4) The space was defined as a basic solid such as a cylinder, a hexahedron, and an octagonal box, and was developed into a complex shape by the recessed windows. 5) Historical vocabularies such as an arch, a vault, and a dome were reinterpreted in new ways by kahn's own eyes. 6) Haying diverse shapes, the skylights enrich the space in terms of form. C) Daylight feature: 7) The vertical light entering through the skylights creates a solemn and mysterious atmosphere. 8) Given the shadows from the windows that change according to time, the interior space becomes a very vivid space. D) Material feature: 9) Harmonized with cold and smooth materials such as exposed concrete, metal, and glass, the interior space provides a modern atmosphere. 10) Warm appearing wood was used for furniture and part of walls or floors. The effective use of wood takes on a role that is quite complementary to the cold ambience of the smooth and cold materials. 11) With flexibility In building shapes, the concrete becomes the form-endowing materials.

Recently, space branding has been used as a branding method for many companies because space communication is a way of utilizing space in a wide range of ways. However, generally speaking, communication only focuses on goods and information about brands and does not focus on consumer's stories. The purpose of this study is to present the communication of " Back to Harakenya " in concept of Harakeya as a solution to this problem and confirm its effectiveness through examples. We selected on the range of " cosmetics brand ", " food and beverage brand ", " brand brand " and " fashion brand " which can used as a direct experience as a marketing method, which is a good condition for communication. Based on that, Harakenya selected cases as spaces with the concept of "Back to Harakenya". Previously, Harakenya's concept of "Back to Harakenya" and his designs appears three features. First, it transforms into various being secondly, it generates active imagination and it contains at least as many things as possible. This resulted in the effect that people remember the image with a clear image. Based on this study, We investigated to draw a result of effects through how the design expression is made in the spaces of Space Branding and how the "Back to Harakenya" communication is taking place in the space. Through these studies, the design and communication method of Harakenya's "Back to Harakenya" concept helps us to remember the brand clearly and furthermore, we confirmed that the brand value can be improved.

The four skills of a language are basically required for a communication. They are very important for a learner to develop the balanced language acquisition. Today both listening and speaking skills are emphasized in the global era rather than reading and writing proficiencies. The reason is really why the learners' communicative competence is more needed than the accurate knowledge of a structure in the language. For this reason, the listening comprehension should be taught effectively using the following strategies. First, the sound difference of a language must be taught. Language is a complicated process to convey the comprehensive meaning combined with the internal and external factors of a language. In other words, the meaning for the sound of language should be transmitted by the unit of vocabulary and syntax. Second, a good listening comprehension requires the familiarity and much experience with a lot of English words to understand English sentences unconsciously. Third, as understanding the structure of language is effective for the listening comprehension, the better listening comprehension can be possible through the meaningful exercise. Fourth, the compound process of listening comprehension requires the comprehensive understanding of language, but not the separate understanding of language. Fifth, the appropriate application of the multimedia courseware helps improve the listening comprehension better than that of the existing audio, video, tape recorder and so on. Using multimedia courseware is useful as follows: A learner is able to take as much lesson as he/she wants. It does take little time to repeat about what he/she takes a lesson. It gives the lively picture with the native speakers' voices. It gives him/her(a learner) a feedback effect continuously through the interaction of computer. It controls his/her lesson in accordance with the level of a learner.

This paper describes the powering, seakeeping and maneuvering performances for a 2,500-ton class trimaran. Influence of the side-hull forms and location of those in longitudinal and transverse direction to resistance performance was systematically investigated by a series of model tests and numerical calculations. It was found that the longitudinal location of side-hulls was the most influential design parameter to the resistance performance of the trimaran and the optimum location of side-hull depends on ship speeds. When the side-hull stem is located near the primary wave hollow generated by the main hull, the trimaran shows the best resistance performance. Powering performance of the trimaran is superior to those of similar mono-hull ships. Seakeeping model tests for the trimaran were executed and the results were compared with the theoretical results of a similar mono-hull ship. Generally speaking, seakeeping performance of the trimaran is superior to that of a mono-hull ship. In particular, pitching and rolling performance of the trimaran is excellent, which is due to the increased length and breadth. Maneuvering model tests using a HPMM equipment were executed to evaluate the maneuvering performance of the trimaran. Maneuvering simulation was performed using the maneuvering coefficients from the model tests. The results show that the control ability of heading angle and the direction keeping stability of the trimaran is excellent, even though the turning performance is rather worse compared to those of a similar mono-hull ship.

View of the recent expansion of ASEAN, Korea must take some measure to cope with them. This paper is aim for suggesting on commercial cooperation between Korea and ASEAN through transition of ASEAN. Generally speaking Southeast Asia can be divided into mainland Southeast Asia and maritime Southeast Asia. ASEAN is association Southeast Asian nations. Korea has been a dialogue partner of ASEAN since 1991, and through the ASEAN plus three try to come true East Asian cooperation. but the level of public awareness of Korea in ASEAN remains very low to compare with China and Japan. Korea and ASEAN have not become the closest of friends in East Asian even though the two are good commercial partners. Korean ODA for ASEAN must be linked with Korean firm's trade and investment for ASEAN to show synergy effect. Korea should analyze ASEAN's plan for ASEAN Economic Community and find potential development needs of ASEAN. Korea and ASEAN want to become ASIA's FTA Hub. such as great vision can come true if Korea cooperate sincerely with ASEAN.

There are various defects caused by trauma or resection of maignant tumor in the orofacial region, which can be reconstructed with various regional and pararegional flaps. Among these defects, it is very difficult to reconstruct palatal and midfacial defects after maxillectomy and patients have problems in speaking and swallowing of food. Therefore it is very important for surgeons to reconstruct these defects functionally and esthetically and to return the patients to the normal social activity. These defects are usually obturated with prosthodontic appliances to assist the phonation and swallowing. But nowadays surgical reconstruction by various flaps was considered and performed for better rehabilitation. For this purpose the forehead flap, the nasolabial flap, the tongue flap, the sternocleidomastoideous flap, the temporal flap, the latissimus dorsi flap, the scapular flap etc. are used. We reconstructed small-sized plalatal defects with tongue flap, medium-sized palatal and maxillary defects after maxillectomy with temporal myofascial flap and large midfacial defects including eyeball exenteration with latissimus dorsi myocutaneous flaps. Here we are to report 5 cases of these flaps used for the reconstruction of palatal and midfacial defects and consider the versatility, reliability and limitation in use of these flaps.
