The above study is based upon the Theory of Five Woon(Reasons) and Six Qi(Climates), namely Five dynamic Yin and Yang, the principle of five-six combination, the rules of ten periodically changing Woon and twelve periodically changing Qi, and its reference to the main chapters of the theory by several experts. After careful, comprehensive research and study, the followings are concluded. 1. The Theory of Five Woon and Six Qi controls all of the physical phenomena of the universe, yet it originates from Essence of the Sky that is replete and in constant motion within the abysmal expanse of the universe. So it is natural to claim that it is the Essence of the universe that is the source of the variety of phenomena in nature. 2. There is order of dynamics in the Essence and it is Yin Yang Five Movement and expressed by Five Woon and Six Qi. Therefore the Five Woon and Six Qi, which is the climatic changes of nature, is the basis and condition for all of the natural, physical occurrences including the organic phenomena of human beings. 3. Since the Sky embodied the number Five, and the Earth the number Six, Qi of the Sky itself is consequently Five Woon and Qi of the Earth itself is Six Qi. 4. In Sixty Repetition Intervals (Yuk Sip Kap Ja), the Sky took the number Six, designating the six times repetition of the ten Intervals of the Sky and the Earth chose the number Five, symbolizing five times recurrence of the twelve Intervals of the Earth. Though the number for the Sky is Five and the number for the Earth is Six, the two combine and interact in order for the Sky to exploit the number Six and for the Earth to use the number Five. This interplay implies the relationship of operation and principle of Yin in Yang and Yang in Yin. 5. There seems to be clear and intimate association between five dynamics, five bearings and five Qi' in nature and five organs, five stamina, and five emotions in physiological activities of human beings. Such an correlation apparently demonstrates the idea of climatic changes of the universe in balance among human beings, the Sky, and the Earth. 6. Because nature is of an endlessly dynamic organism itself, to have changes must mear there being movements. Thus the climatic changes in nature are the subsequent consummation of the interaction in mutual balance and unbalance of the rise and fall of the Five Woon and Six Qi. 7. The interpretation, by Chang Ji Chong of "Yin and Yang of the Sky are for birth and growth and Yin and Yang of the Earth for demise and interment" as an explanation that the first half is mainly for life and the second half for death, appears to be correct by his view that there is balance and harmony between the long and short and the strong and weak. 8. In addition to Three Yang and Three Yin, as attributes of the Intervals of the Sky and the twelve Intervals of the Earth, Five Woon and Six Qi are utilized in the annual observation of the perpetual changes of climates.

There are differing opinions among scholars as to whether "chuseo" (ugly writing) should be considered as one of the schools in modern calligraphy. Those who do not recognize "chuseo" argue that it lacks traditional rules for stroke formation and therefore loses its distinctiveness. However, the existence and development of "chuseo" are closely related to the constant exploration and reform of modern calligraphy, as well as the increasing aesthetic awareness and changing aesthetic standards of calligraphers with changing times. As a result, there are now more people who recognize "chuseo" as a legitimate form of calligraphy. Calligraphers who lead the times learn and accumulate experiences by adhering to traditional calligraphic principles. However, there are calligraphers who discard the traditional Confucian concept of "chungyong" (中庸) and display "ugliness" in their works. Ok Heung-hwa and Jeung Sang are two such calligraphers who created their own style by incorporating ancient oracle bone inscriptions as their main focus and folk calligraphy as their bloodline. This paper aims to explore and study the definition and formation process of "chuseo" by analyzing the works of Ok Heung-hwa and Jeung Sang. At the same time, it aims to summarize the characteristics and aesthetic beauty of "chuseo".

As personal robots coexist with a person with a role to help a person, while adapting various human life and environment, the personal robots have to accommodate frequently-changing or different-from-home-to-home environment. In addition, personal robots may have many kinds of different Kinematic configurations depending on the capabilities. Some may have a mobile base and others may have arms and a head. The motivation of this study arises from this not-well-defined home environment and varying Kinematic configuration. So the goal of this study is to develop a general control architecture for personal robots. There exist three major architectures; deliberative, reactive and hybrid. We found that these are applicable only for the defined environment with a fixed Kinematic configuration. Neither could accommodate the above two requirements. For the general solution, we propose a Supervised Hybrid Architecture (SHA), in which we use double layers of deliberative and reactive controls, distributed control with a modular design of Kinematic configurations, and real-time Linux OS. Deliberative and reactive actions interact through a corresponding arbitrator. These arbitrators help a robot to choose an appropriate architecture depending on the current situation to successfully perform a given task. The distributed control modules communicate through IEEE 1394 for the easy expandability. With a personal robot platform with a mobile base, two arms, a head and a pan-tilt stereo eye system, we tested the developed SHA for static as well as dynamic environments. For this application, we developed decision-making rules for selecting appropriate control methods for several situations of navigation task. Examples are shown to show the effectiveness.

The dissemination of smartphones is being spread and supplementary services using smartphones are increasing and various as the Mobile network and device are developing rapidly, so smartphones that enables to provide a wide range of services is expected to receive the most attention. It makes users listen to music anytime, anywhere in real-time, use useful applications, and access to Internet to search for information. The service environment is changing on PC into Mobile due to the change of the circumstance mentioned above. these services are done by using just location information rather than other context, and users have to search services and use them. It is essential to have Context-aware technology for personalization recommendation services and the appropriate representation and definition of Context information for context-aware. Ontology is possible to represent knowledge freely and knowledge can be extended by inferring. In addition, design of the ontology model is needed according to the purposes of utilization. This paper used context-aware technologies to implement a user personalization recommendation service. It also defined the context through OWL modeling for user personalization recommendation service and used inference rules and inference engine for context reasoning.

This study presents a rule-based urban image classification method for time series analysis of changes in the vicinity of Asan-si and Cheonan-si in Chungcheongnam-do, using Landsat satellite images (1991-2006). The area has been highly developed through the relocation of industrial facilities, land development, construction of a high-speed railroad, and an extension of the subway. To determine the yearly changing pattern of the urban area, eleven classes were made depending on the trend of development. An algorithm was generalized for the rules to be applied as an unsupervised classification, without the need of training area. The analysis results show that the urban zone of the research area has increased by about 1.53 times, and each correlation graph confirmed the distribution of the Built Up Index (BUI) values for each class. To evaluate the rule-based classification, coverage and accuracy were assessed. When Optimal allowable factor=0.36, the coverage of the rule was 98.4%, and for the test using ground data from 1991 to 2006, overall accuracy was 99.49%. It was confirmed that the method suggested to determine the maximum allowable factor correlates to the accuracy test results using ground data. Among the multiple images, available data was used as best as possible and classification accuracy could be improved since optimal classification to suit objectives was possible. The rule-based urban image classification method is expected to be applied to time series image analyses such as thematic mapping for urban development, urban development, and monitoring of environmental changes.

Our nation has experienced remarkable growth over the half a century. Nonetheless, there is still much room for improvement in the area of Environment, Health and Safety (EHS). In particular, frequency and severity of industrial accidents did not considerably improve compared to the economic and social progress we made. The main objective of this research is to analyze what plans and actions are required for companies to promote industrial safety by 1) fostering functional competencies of EHS staffs and 2) effectively and proactively responding to rapidly changing EHS environment. For this research, EHS staffs from five large companies in Korea were surveyed. Most respondents indicated that one of key expertise required by EHS staffs is capabilities to effectively deal with changes to various domestic and international EHS-related laws and regulations. Furthermore, a predominant number of respondents commented that it is imperative for EHS staffs to have a broad knowledge of business management. As for internal issues that EHS staffs encounter within their organizations, many pointed out that their EHS vision is not sufficiently shared throughout the organization, and that the rules of leadership are critical in solving this issue. On the other hand, the survey respondents also raised an issue of limited EHS-related investments due to slow economy. As a solution, they proposed ways to align EHS organization's performance with the company's performance. Based on this survey, issues and solutions for EHS organizations were identified. Results of this research can benefit companies that plan to newly establish or further expand EHS organization.

Outsourcing, importing of publishing metadata and revitalizing copy cataloging have reduced importance of traditional cataloging. Request of interoperability between other communities and business integration of related system also have changed the meaning of library catalog. Furthermore, newly declared principle and rules are totally different to existing AACR, MARC, measures to cataloging education for next generation seems to be urgently needed. In this study, firstly put together a series of discussion about future cataloging and new role of cataloging librarian, and secondly basis on it, suggest direction of cataloging education course which divided two sectors. One is for students who are undergraduated, and another is for current cataloger at working level. In basic training, it should contain principle of knowledge organization and diverse resources and its relationship, encoding scheme and its practice. The other hand, in re-education training, it should include that re-recognition about new concept of bibliographic world, changing vocabulary and encoding scheme, furthermore metadata scheme about diverse resources which library have accepted, and its integration.

Three materials SUS304, 9% Ni steel and Al 5083-O alloy, which are considered possible candidate for International Maritime Organization (IMO) type B Cargo Containment System, were studied. Monotonic tensile, fatigue, fatigue crack growth rate and Crack Tip Opening Displacement tests were carried out at room, intermediate low ($-100^{\circ}C$) and cryogenic ($-163^{\circ}C$) temperatures. The initial yield and tensile strengths of all materials tended to increase with decreasing temperature, whereas the change in elastic modulus was not as remarkable. The largest and smallest improvement ratio of the initial yield strengths due to a temperature reduction were observed in the SUS304 and Al 5083-O alloy, respectively. The fatigue strengths of the three materials increased with decreasing temperature. The largest increase in fatigue strength was observed in the Al 5083-O alloy, whereas the 9% Ni steel sample showed the smallest increase. In the fatigue crack growth rate test, SUS304 and Al 5083-O alloy showed a decrease in the crack propagation rate, due to decrease in temperature, but no visible improvement in da/dN was observed in the case of 9% Ni steel. In the Crack Tip Opening Displacement (CTOD) test, CTOD values were converted to critical crack length for the comparison with different thickness specimens. The critical crack length tended to decrease in the case of SUS304 and increase for the Al 5083-O alloy with decreasing temperature. In case of 9% Ni steel, change of critical crack length was not observed due to temperature decrease. In addition, the changing material properties according to the temperature of the LNG tank were analyzed according to the international code for the construction and equipment of ships carrying liquefied gases in bulk (IGC code) and the rules of classifications.

The region of Southeast Asia had already experienced rapid urbanization and cultural change before the East Asia region did. None the less, nowadays shophouses and rowhouses still form the major portion of streets in Chinese town in Southeast Asia countries. The purpose of this study is to examine the adaptation process of shophouse and rowhouse in the Southeast Asia region and the architectural characteristics between the middle of 18th and the early of 20th, which Chinese people of the region inherit and develop, for more thorough understanding of cultural adaptability and regionalism of Chinese architecture in Southeast Asia. The common fact found in the Southeast Asia region is that Chinese people in countries of this region gradually started to live densely as a group in a certain zone in city area since they got to play important roles in commerce, trade and service works related with cities, due to European countries' advance into Southeast Asia and their construction of colonial cities in the region. Chinese people in the region utilized residential rowhouse and special shophouse, which is a kind of shop adapted from rowhouses' sitting room or storage, for their commercial and industrial activities in urban areas, which had problems of limited space. They also realized high densities through vertical expansion of space in order to adjust to changing urban structure under execution of urban planning in cities of colonial area and rapid urbanization. Even though residence of Chinese in Southeast Asia was influenced by new political, social, economic and cultural rules of European colonies in Southeast Asia, it has continuously succeeded to the cultural tradition of China, their home country, in terms of planning principle which puts air well in the middle and hierarchial spacial construction method. Appearance of the open connected verandah, designed by Stamford Raffles, the founder of Singapore, can be regarded as one of the architectural characters. Hence, Chinese residence in cities of Southeast Asia can be understood as a new regional architectural culture in the context of European countries' urban planning and urbanization of colonial areas, Immigrants from southern China and their role, their adjustment to urban areas by utilizing mixed type houses of residence and business, cultural tradition of Chinese home country.

This study aims to analyze families and the kinship concepts in Korean laws based on meanings, boundaries, and functions. Korean culture is in the process of changing from traditional familism to democratic individualism, yet this is not a simple transition. In recent times, many people have come to look at family life from both traditional and individual perspectives, so their family values are inconsistent with each other. Therefore, this creates many family conflicts. As a result of this problem, I have analyzed families and the kinship concepts in Korean laws based on meanings, boundaries, and functions. Because laws regulate and reflect our everyday life, it is meaningful to review these laws. The results are as follow: First, the meaning of family in Korean laws is to respect other family members, and democratic family relationships. Second, the family boundaries are very different depending on the laws. The core boundary is the nuclear family, but in addition to the nuclear family, the parents of the wife and husband, the family of origin and the kin living together are included in the family member regulations. Third, the functions of the family are caring, education, rules for the living place, child discipline, supporting each other, guardianship for the family members, succession of family assets, and legal accusation rights. Kinship plays an important role in determining child guardianship, permission of a minor to marry, and authority over legal incompetency. Therefore, there are some contradictions between individualism and patriarchy in Korean laws, and these can have an influence on the conflicts between family members in the everyday life.
