Administrative Role-Based Access Control(ARBAC) is a typical model for decentralized authority management by plural security administrators. They have their work range on the role hierarchy. A problem is that legal modification of role hierarch may induce unexpected side effect. Role-Role Assignment 97(RRA97) model introduced some complex integrity principles to prevent the unexpected side effect based on geometric approach. We introduce simple and new one integrity principle based on simple set theory. It is simple and intuitive. It can substitute for all integrity principles of RRA97 model.

Through his geometric design, the Cyprus born fashion designer Hussein Chalayan raises intriguing questions about the very fact of wearing clothes. By purposefully displacing the function of each part of the clothing, such as neck line, hem line, seam, sleeve, etc., Chalayan transforms the meaning of the body that wears clothes. of the human subject as a sovereign possessor of the clothing and the visibility related to fashion. This transformation is achieved by distorting the spaces of his clothing in an unorthodox way. This thesis argues that the significance of such a practice can not be properly understood without relation to the current debate on deconstructionism under way in humanities. Instead of immediately negating the modern frame of Ideas and practices, deconstructionism asks what the assumptions for the modern regime of truth is. In this process, things that lead human beings to sovereign master of knowledge and truth such as reason, subject, body and vision are questioned. In the same context, Chalayan's design not only forces us to rethink the very function of dividing inside and outside by the clothing but also the meaning of boundary operating in numerous sites of modern life. As the human subject is not something pre-given but constructed according to the cultural representation, to which the clothing belongs, fashion can be evaluated to be an active ingredient of constructing the subject. Therefore, Hussein Chalayan's design is at the cross road between the modern and the postmodern regime of fashion.

Korean trains pass many mountain areas, so the volume of structures like bridge and tunnel has large part of railway lines. Train speed-up naturally needs a straight line in railway, then structures are increasing, and the length of structure has more than 70% in Kyongbu high-speed railway. The stiffness of bridge and tunnel is higher than the soil in the roadbed in spite of dynamic difference in vibration and displacement. Differences in stiffness have more dynamic effects and increase the deformation and destruction in the track and roadbed. This influences passenger's comfort and the safety of operation, and it needs more track maintenance. This study selected tunnel with ballast track, tunnel with concrete track, and structure's approaches with short maintenance cycle in the roadbed and had track acceleration tests and track liner inspections using track master in the field. This study will measure periodically to structure's approaches which have very fast track irregularity and analyze dynamic differences and track irregularity near structure's approaches, so realize the cause of track irregularity of structure's approaches and use basic data for reasonably strengthening method of structure's approaches.

The thesis suggests the proper ftaining methods and their future direction in order for bodyguards to have a general idea of basic skills of escort and develop them. What is meant by basic skills are the basic abilities of bodyguards for escort indluding physical strength, martial arts, and manipulation of equipment. The equipment in the thesis is confined to guns. The following are the requircments for the training of basic skills; 1, A bodyguard should be careful not to expose any equipment he uses his basic skills so that he does not make others feel uncomfortable. 2. He should be trained to give the safety of the person(s) escorted the first priority. 3. He should have the ability to take care of at least one attacker. 4. He should be trained to be able to evaluate the trend of attacks and keep up with it. Training fo basic skills are divided into three parts-physical training, martial arts and use of equipment. Each part is divided into basic training, applied training, and professional training, which again are integrated in one master training program. Especially, development of equipment which helps to take care of attacker(s) quickly without casualties and learning to use the equipment efficiently will accelerate the improvement of basic skills. The author of the thesis worked for Presidential Security Service for fourteen years and suggests the most efficient, protection-oriented way of training based on his experience.

The research want to know about form creation method's special quality that found in digital construction design process that using digital media, and they comparison analysis that who positive using digital media, Frank O. Gehry, Peter Eisenman, Greg Lynn, UN studio's work. First, In digital design process using digital media is make full use to design unfolding step and application way can change by architect's recognition difference of using digital media and each architect's design general idea unfolding process, and it means form creation process can change. Second, In digital design process a building form doesn't design adaptation to construction system, they directly design the third dimension form. So, they deduction a new form that unification and integration. Third, the architect that appear's in digital design process's part is existing, data from position of the master which it selects the coding selects the outcome goods which appears in computer operation with coordinator role of the originality and construction sense which it is visible.

The Healthy Family Act was established in 2004 to prevent problems of the family and increase thehealthy characteristic of the general family. According to this Act, Healthy Family Support Centers (HFSCs) were founded as a new part of the family welfare institution. The purpose of HFSCs is providing various welfare services to enhance the health and well-being of families in the community. This study investigated the organizational system and evaluation strategies of HFSCs. This research comprised a descriptive study of the organizational system and evaluation strategies of HFSC. The study sample consisted of 217 faculty and field workers. Data were collected from December 2004 to January 2005 and analyzed by frequencies, mean, standard deviation and ANOVA. The results were as follows. First, HFSC's organization should consist of family education, family counseling, family culture-marketing, and network teams. Second, healthy family specialists should have a national certificate of qualifications also they should have more than master's degree level. Third, evaluation of HFSCs should be adapt an incentive system.

This research presents a three-dimensional modeling technique for a flexible sheet. A relative coordinate formulation is used to represent the kinematics of the sheet. The three-dimensional flexible sheet is modeled by multi-rigid bodies interconnected by out-of-plane joints and plate force elements. A parent node is designated as a master body and is connected to the ground by a floating joint to cover the rigid motion of the flexible sheet in space. Since the in-plane deformation of a sheet such as a paper and a film is relatively small, compared to out-of-plane deformation, only the out-of-plane deformation is accounted for in this research. The recursive formulation has been adopted to solve the equations of motion efficiently. An example is presented to show the validity of the proposed method.

Overlay model had several advantages to describe hysteretic behavior of material and showed good capability for many engineering materials. However, this model is only applicable to material obeying Masing postulate. Some materials such as 316L stainless steel do not follow Masing postulate and show cyclic hardening(or softening) and strain range dependence. Low cycle fatigue tests of 316L stainless steel at 600$^{\circ}C$ were performed to investigate the characteristics of cyclic behavior of non-Masing material. From all tests cyclic softening was observed. There were differences in elastic limit of hysteresis loop according to applied strain range. To consider these features, modified overlay model was developed. Yield stresses of subelements were divided into isotropic and anisotropic part to describe the non-Masing behavior. The plastic strain range memorization was introduced to consider the strain range dependence. The prediction using modified overlay model showed a good accordance to actual hysteresis loops.

Purpose -This paper is to study the process of the negative effects of Sino-foreign joint ventures, hoping to find out an effective path in which local enterprises can avoid the risks in the utilization of foreign capital, and ultimately achieve independent innovation. Research design, data, and methodology -The outflow of assets, the loss of local brands and the "technology hollowing-out" problem brought by joint ventures is becoming more and more serious. Based on conflict analysis graph model, this paper takes Yuhuan joint venture as an example to identify the conflict problem in Sino-foreign joint ventures. Results -The results of the stability analysis show that establishing joint venture cannot really realize the introduction of technology because the technology is fully controlled by the foreign part. So when introducing foreign capital, local enterprises should participate in R&D and master the initiative. Conclusions - Local enterprises should pay attention to patent containment and technology blockade of multinationals. Domestic enterprises should try to protect state-owned assets and local brands in Sino-foreign joint ventures. Independent innovation is the most effective strategy for the development of enterprises in China.

The "Ojangyukbudo五臟六腑圖", cited in "Ojangmun五藏門" of "Euibangyuchwi醫方類聚", was written by Ho Eum, a woman Taoist master who lived in Dang Dynasty. She put stress on the medical theory of the five viscera and the six entrails to overcome the side effects of Oedansul[alchemy for immortality] which prevailed during the period of Dang, and established a medical system which was based on six viscera and entrails and combined with Taoist theories. The major features of "Ojangyukbudo五臟六腑圖" can be summarized in the six-part medical system, the diagrams which describe the principles of viscera and entrails in detail, and the methods of Suyang[修養法:mental training], Tonap[吐納 法:respiration] and Doin[導引法:physical training] for regulating the functions of viscera and entrails and curing diseases. The "Dongeuibogam東醫寶鑑", a medical book from Joseon Dynasty, accepted the methods of Suyang and Doin, and the "Yorayak要略", a transcript from Joseon's later period, accepted the Taoist medicine based on six viscera and entrails, combined it with the contents of "Dongeuibogam東醫寶鑑", thus composing a unique medical system. Especially, the "Yorayak要略" is a literature important for the study of Joseon's Taoist medicine.
