Surgery with the computer navigation system can make it possible to identify important anatomical structures which are difficult to be confirmed with the naked eye in the operation, and has extended their applications in various surgical fields. The head and neck surgery especially requires detailed anatomical knowledges and these knowledges have influences on postoperative functions and esthetics of a patient. In the orthognathic surgery, we should take osteotomies in the precise locations of the jawbones and move segments to the intended positions. There are so many important anatomical structures around the osteotomy-sites in the orthognathic surgery that the prevention of damage to these structures to obtain satisfactory results without any complication. There are vessels of the pterygoid plexus posterior to the pterygoid plate in the maxilla and the mandibular nerve enters the mandibluar foramen in the mandibular ramus. These locations should be confirmed perioperatively to avoid any injury to these structures. The navigation-assisted surgery may be helpful for this purpose. We performed navigational orthognathic surgeries with preoperative CT images and obtained satisfactory results. The osteotomy was performed in the proper location and damaging the surrounding important anatomical structures was avoided by keeping the saw away from them with the real-time navigation. It may be required to develop proper devices and protocols for the navigation-assisted orthognathic surgery.

The purpose of this study was to investigate characteristics of teenagers' perceptions to bullies according to the classification types of Q-methodology. The results of the analysis were classified in 5 types. Type 1, which was the type geared foward solution, showed that they expressed a strong attitude of sympathy and protection towards the victim. However, they had harbored rage and hostile feelings against the assaulter. For example, when they witnessed the bully in action, they positively intervened in the situation. Type 2, which was the observer type, showed that they thought the victims were to blame for their misfortune. Also, when a friend who was left out in the cold by his classmates, they were just watched without showing any special interest. Type 3, which was the type of conflict, indicated that they believed that the both the victim and the assaulter should have responsibility. In contrast to the previous type, they had sympathy for the friend who was left out in the cold by his classmates, they had the dual feeling that intended to use the bully under the situation with his friend. Type 4, which was the type of assenting, indicated that they assumed an indifferent attitude to the situation, while they implied assenting to the situation of the friend who had a bad relationship with them. Type 5, which was the negative type, showed that they had the negative view to the situation of bully itself so that they did not recognize the bully as the method of revenge for whatever reason. The results of the study showed that the bully increased the factor of stress to school life of the victim or assaulter, even in the subjective position. The perception of the bully should change according to the characteristics of the types of people and it is necessary to study how to cope with the situations.

Recently, many countries have placed great attention on energy security and climate changes. Governments are promoting the construction of renewable energy projects with regulatory support in Korea. Despite an increasing penetration of renewable resources, however, the photovoltaic and wind power are underutilized due to the endemic problems such as difficulties of output control and intermittent output. The Energy Storage System (ESS) is proposed as a good solution for solving the problems and has been studied in both the private business and the government. However, because of inefficient aspects, the research has been carried out for improving high costs and a small capacity. In addition, the ESS is currently installed for using only one purpose which is frequency regulation or transmission congestion relief such that has an economic limitation. Therefore, methods which are becoming economically justifiable to increase the penetration of the ESS is required. Thus, this paper presents in terms of operation efficiency to improve economic feasibility of the ESS currently used. mainly, there are two aspects for the operation efficiency. Firstly, it is intended to improve the utilization rate through a process that can utilize the ESS for various purposes. It is necessary to be able to use for other purposes by classifying and clustering for increasing the efficiency of availability. The clustering method is proposed to conduct the grouping the ESS. Especially, it is proposed to utilize ESS for frequency regulation service which is the one of ancillary services in the power system. Through case studies, it is confirmed to secure the necessary resources by clustering small size ESS.

This study intended to investigate the relationship between father's/mother's values(materialism, competitive achievement pressure, neighborhood relations), father/mother-student emotional intimacy & father's/mother's over control and university student's alienation, and examin the relative influences of independent variables on university student's alienation. For this purpose, data were obtained from 402 male 7nd female university students in Seoul and Inchon, and analyzed by factor analysis, Cronbach's $\alpha$, frequencies, %, Pearson's r and stepwise multiple regression. The major findings were as follows : 1) father's and mother's values had significant relations to university student's alienation. As father and mother had more materialism and competitive achievement pressure, their university student was more alienated, and as father and mother had more neighborhood relations, the student was less alienated. 2) Emotional intimacy between father/mother and student had negative relation to university student's alienation. As the level of emotional intimacy was higher, the student was less alienated 3) Father's and mother's over control had positive relations to university student's alienation. As father's and mother's over control was higher, the student was more alienated. 4) Mother's neighborhood relations, father's and mother's over control, mother-student emotional intimacy and father's materialism had influences on university student's alienation in descending order. These independent variables explained 25. 0 % of the total valiance. Father's materialism and father's/mother's over control increased the level of university student's alienation, but mother's neighborhood relations and mother-student emotional intimacy decreased the bevel of student's alienation. Emerging evidences suggested that in order to prevent or decrease the university student's alienation, their parents should have less materialism and more neighborhood relations, and should not use over control on their university student but produce more emotional support.

In Korean clothing industry, most of the manufactures produce garments by subcon-tractors partially or entirely. It is very often that the design part is remote from production part and there is miscommunication between these two parts resulting dissatisfaction to both. Therefore it is very important to communicate the manufacturing information clearly and quickly to produce garments exactly the design part intended. Also to automate the clothing out how to produce and use the information objectively and efficiently. As a first step of moving to automation, the purpose of the research is to find out how manufacturing information and data are communicated in clothing manufacturing at present. In order to follow the information flow of a cer-tain manufacturer, the case study method was used. The case study samples were 12 clothing firms of 13 brands. The results and suggestions are as follows :- 1. A manufacturing information is communicated through paper documents such as“Production Order”, sample and patterns. At present, a production order sheet is the most efficient communication media, which comprises most of the information being communicated. 2. A manufacturing information comprises control information on the product, design in-formation, pattern information, cutting information, material information, sewing information, production schedule information, quality control information, costing information and information about the subcontractors. 3. A manufacturing is not quite objective except pattern information and cutting information which is presented by CAD systems. The communication of design information and sewing information should be somehow more objective. 4. There is not much information from a subcontractor. Considering that a subcontractor is the other partener of the communication, more information from the subcontractor is required for both benefit. 5. A designer produce most of the manufacturing information, but the information is communicated through a production manager to the subcontractor. The difference between the information maker and information communicator can cause any miscommunication. In future automated manufacturing, it will be possible for the designer to communicate to the manufacturer directly from the early stage of designing.

The purpose of this study was to analyze the characteristics of the Minimal Art represented in the second half 20th century fashion. All the mode of dress worn this century have developed from the stimulus of a chang-ing society fired by new discoveries and a zest for the new and different. It would appear that even more dramatic changes will soon occur in our clothing styles the effects of which will be farreaching. Many of today's styles intended to dress our psyche rather than our bodies and this if fully understood by the new designers whose influ-ence will become increasingly more potent as we approach the new century. The highly developed material civilization resulted in human alienations environmental distruption, l By this fact human being of the 20th century was to overcome social com-plexity. Accordingly their search for simplicity was interested in the 60's style. Especially the formativeness of the 60s style was repre-sented in the second half 20th century fashion. In this paper it was focused that how the characteristics of the Minimal Art was expressed in the second half 20th century fashion. minimalism was a quest for basic elements repesenting the fundamental esthetic values of art. without regard to issues of content. At its most extreme it reduced art not ot an eter-nal essence but to an arid simplicity. "Primary Structure" the most suitable name suggested for this type conveys its two salient characteristics : extreme simplicity of shapes and a kinship with architecture. minimalist works are charcterized by huge dimensions coldness and absolute aesthetic neutrality. minimalist artists ambition is to de-fine through the most rudimentary materials such as plywood galvanized iron aluminum plastic and wood a new order of the space. The environment is just as important as the object itself. Similary the use of new tough materials. such as vinyl metal and plastic at late half of the 20th century fashion related to the formativeness of the Minimal Art. And the style of 20th fashion was holded the internal meanings in common the formativeness of the Minimal Aet thorough the various texture pat-tern silhouette etc.uette etc.

For this process, research steps were as follows : 1. Understanding drag, drag queen and drag king in social, psychological context as well as in gender context. 2. Finding visualized forms which drag performance interchange with mass media 3. Analyzing similarities and differences between drag queen's fashion and drag king's fashion. 4. Examining the aesthetical characteristics and the value of drag queen's and drag king's fashion. The results of characteristics of drag queen's fashion could be categorized into stereotype, mimicry, kitch, inconsistency and commercialism. And the characteristics of drag king's fashion could be divided into reality, self-consciousness, mimicry, inconsistency, subversion and multiplicity. Drag queens create plausible impressions of feminity through the use of wigs, dresses, jewelry, makeup, hormones and through &role Playing&. Similarly drag kings produce a plausible masculinity taking gay male aesthetic using suits, crotch stuffers, facial hair, and greased hair. Male and female impersonation produce very different notions of gender performance for male and female embodiment. Drag kings' performance of masculinity demands authentic property of bodies so rather nonperformative, while drag queens' performance of femininity depends on more visible and theatrical fashion.

The purpose of this study was to develop a program of oral health education for children and to furnish basic data contributing to the improvement of children's oral health. In this study, we tried to analyze and discover the types of recognition in parents of children's oral care. With the use of Q-methodology that could systematically and scientifically estimate the subjectivity of humans, 28 parents were collected as a P-sample. 3 general types were discovered. The characteristics of each type were the following: Type 1. "Serious consideration of prevention care type" took a positive attitude to their children's oral care, were knowledgable, and maintained high concern about oral care. They regularly visited dentists for prevention and believed in caries prevention through brushing teeth. They also put high trust in dentists. Type 2. "Disposition by the existing state type" believed that caries could develop even with brushing teeth and could be inherited from parents, Practically, they had a passive attitude to their children's oral care depending on stages and were more concerned with the appearance of dentition than with their children's oral health. Type 3. "Home care-centered type" had less knowledge about children's oral care than the other two types and was careless for teeth prevention. Therefore, they had not intended to participate in the oral health education program.

This study is an effort to make policy suggestions by analysing the current health examination program as a benefit service provided by the national health insurance system, including health screening for the insured, screening of cancer and chronic diseases for their dependents. Analyses found some issues being gave attention to; 1) The insured under the community health insurance system do not get the health examination benefit. A program for them should be set to have equity in benefit services. 2) Low rates of using screen services compromise purpose and the efficiency the services have first intended to. An immediate attention should be made to increase low rate of use of screen test to detect chronic diseases in particular. 3) Selection of diseases and test items covered by health examination program does not reflect the need of the insured, but to reflect financial resources of the national health insurance system. 4) Lack of health screening facilities and their geographical maldistribution is observed, which with preference of a general hospital as a screening post by the insured may lead to unreliable test. 5) A follow-up system should have been developed for the suspected classified by test results of carrying chronic diseases. They should be cared for within the health examination program. Public health care systems incorporate such a system, along with caring for those who are in need of having a health counselling on preventive care. In conclusion, the national health insurance system should be a medical insurance of giving a higher priority on preventive care benefits, health examination program in particular. That could be done by making rearrangements of test items, screening methods and system, rationalizing current reimbursement system of service fee, increasing accessibility to and utilization of the services, and making an establishment of follow-up system.

The purpose of this study is to present the dwelling space by attaching or inserting the mobile space unit to the fixed building by providing the temporary dwelling space for those suffering from flood disaster, natural disaster or solitary old people or the space and program that the completed building in the city can not provide such as temporary events in the bridge, passage space, walking space for the handicapped, stores located between street blocks, and plaza. Therefore, this study was intended to investigate temporary dwelling space through the composition of space and the experiment of the applicability of the program through the methods of movement, folding, module, expansion and evolution of mobile space. An attempt was made to apply the concept of ‘mobile space’ to the dwelling space not only with a focus on the freedom of variable and changeable physical movement but also with a focus on the existence of the nomad and the way of thinking that bleaks away from a given value system and code, creates a new value and continues to move to a new domain. This study attempted to analyze how the concept of ‘mobile space’ has been developed in what form and method they have been applied and interpreted in the historical background. It attempted to resolve the concepts of movement and mobility through the experiment so that they might apply to the space of contemporary city. This study attempted to experiment this possibility using the mobile space unit and apply it.
