Visual changes and speed changes in curved sections of highways are more dangerous than straight sections According to the enquetes conducted by Coalition for Transportation Culture in 1999, about 78% of drivers are dissatisfied with traffic guide and safety signs, with lack of visibility being the largest reason with about 27.9% of respondents indicating it as reason for dissatisfaction. In particular, the lack of visibility during nighttime or bad weather not only threatens driver safety due to poor delivery of information, but also affects the service level of highways. Because of this a new delineation must be installed and managed to enhance driver visibility. In this research, an optimal delineation system to enhance traffic safety is presented. In this research drivers effectively obtained information on highway alignment on the curved sections using a retro-reflection type delineation system and a newly-developed internal lighting delineation system to improve safety on the highways. A statistical comparison was conducted and analysis was done for the delineation systems that enhanced visibility through primary and secondary enquaetes. As a result, inside-lighting delineator will be selected in terms of safety at the curve sections. The inside-lighting delineator was more effective than the retro-reflection delineator on visibility, the necessity of reduction of speed and will reduce the hazard at curve sections. It is anticipated that when a delineation system based on this research is installed, a reduction in the number the number and severity of traffic accidents on curved sections will be reduced. In addition this system will more effectively provide drivers with information about highway alignment.

Mitochondrial myopathy is characterized by variable clinical manifestations from mild limb weakness to fatal respiratory failure and central nervous system sequela. But it is a rare event that sleep disordered breathing become a clue of diagnosis for mitochondrial myopathy. We report a case of a 21 year-old man who was diagnosed as mitochondrial myopathy during the investigation for the possible cause of chronic hypoventilation syndrome. Before being admitted to our hospital, he was suspected as having sleep apnea syndrome in another hospital. We re-evaluated the history, physical examination, laboratoy findings and polysomnography in detail. Severe hypoxemia was noted during REM sleep on nocturnal polysomnography and the diagnosis of mitochondrial myopathy was made by muscle biopsy in rectus abdominis muscle. We treated him with bilevel positive airway pressure therapy during sleep and it could reverse the hypoxemia during REM sleep. He could be discharged with improved condition and is being well with the use of this ventilatory assistance.

This study was purposed to evaluate the level of occupational stress and the work-related factors of occupational stress in dental hygienists. The study was conducted during the period from May to October 2010 with study population consisted of 316 dental hygienists. The occupational stress was estimated with questionnaire of the Korean Occupational Stress Scale(KOSS) and the work-related factors were consisted with 9 work characteristics. Data analysis was performed with t-test, ANOVA and multiple regression analysis using SPSS(win ver 18.0) program. The level of occupational stress was $52.42{\pm}4.95$ in dental hygienists. The levels of sub-scales for occupational stress were $64.56{\pm}12.17$ in interpersonal conflict, $59.85{\pm}13.59$ in physical environment, $54.60{\pm}13.51$ in organizational system, $52.37{\pm}11.47$ in job demand, $51.71{\pm}10.58$ in lack of reward, $48.14{\pm}12.97$ in insufficient job control, $46.68{\pm}9.25$ in job insecurity, $41.46{\pm}15.98$ in occupational climate, respectively. According to multiple regression analysis, physical burden and daily repetitive working hour were work-related factors of occupational stress in dental hygienists. To conclude, the occupational stress in dental hygienists was higher than mean score of reference values of occupational stress in Korean workers and methods for reducing work load and work hours considering work characteristics of dental hygienist are needed to prevent occupational stress in dental hygienists.

The amusement design of a large amusement park, including theme park, largely consists of attraction design, the main facilities, and auxiliary facilities design. The purpose of this study was to discuss the physical motion characteristics of major ride, a recently highlighted representative ride attraction, modern people's thirst for stronger stimuli, and some of the right future directions for amusement design. In theme park, there is an growing trend for rides, especially major rides, to be more thrilling, and Newton's Law motion is basically applied. The rides we can often see provides a thrilling experience that is different from that offered by vehicles we use everyday, due to a variety of speed change, namely of acceleration. Every entertainment facilities, including ride attractions, are externally cutting edge with the use of new technology. but internally, poor theme or concept not only makes it difficult to function properly as attraction but poses a severe threat to theme park survival itself. Theme park will be able to exist as a comprehensive entertainment entity, when attractions are designed to have a perfect harmony among story, method and environment with cultural universality.

The austere standard for industrial design and the machine aesthetic reinforced modernism and lasted more than a half century. Pop art and Pop design movements, which were opposite of the elite culture, began to appear as anti-modernism in the late 1950s. With the development of technology, the movements helped to establish humanism design style that reflected the life style of young generation and their culture. From the 1960s. it was a try in order to fulfill psychologically users' needs beyond tasks for physical considerations. The efforts appeared as a various appearance in different contexts. It could settle down on industrial design, based on humanism both from the physical and psychological points ol views, through anti-modernism in the 1960s, commercialism, consumerism and hi-tech in the 1970s, and postmodernism in the 1980s. The design, as a specific style in industrial design, delivers both physical and psychological satisfaction to consumers by using a mixture of human emotions with high technology. Accordingly, this study is to find out and to define the design style that was applied by human emotion and sensibility in design history from the 1960s to the 1980s. It will be underpinnings for the next research about how the design style has developed nowadays.

The current Korean labour movement is at an impasse that is partly sustained by the idea of "strong" transnational corporations (TNCs) versus "weak" labour, and this perception is based on the "global-local dichotomy," wherein TNCs are depicted as abstract and structured entities operating at the global scale and workers are represented as having a concrete and weak presence within the local sphere. As an alternative perspective to break this "global" capital vs. "local" labour dichotomy, I focus on labour geography, which assumes that labour is not simply a factor of production but a sentient spatial actor that (un-)intentionally produces the landscape of capitalism. Borrowing insights from the multi-scalar perspective, this paper aims to understand the actual methods in which workers utilize spatial strategies through an empirical case study of the Nestlé Korea labour union strike in 2003. Based on this case study, this paper claims that workers are both capable of employing coordinated multi-scalar practices and can be more influential to the economic geographies of TNCs. Additionally, it suggests that workers' scalar practices are actually more complicated and multi-directional as a result of their complex and dynamic interactions with political, economic and cultural forces and actors at diverse geographical scales.

Three frequently used documents by researchers on the Japanese colonial period-Classified Police Records of the Japanese Government-General of korea on the Anti-Japanese Movement 舊 朝鮮總督府 警務局 抗日獨立運 動關係 秘密記錄, Trial Records of Gyeongseong District Court 京城地方法院 裁判記錄 and Filed Documents of Gyeongseong District Court 京城地方法院 編綴文書(while the latter two were collected by the National Institute of Korean History, the former was collected by Asiatic Research Institute of Korea University)-are among the same records group that the Prosecutor's Office of Gyeongseong District Court produced through registration and compilation. As contents related to ideology suppression and thought control were numerous, it could be assumed that most of the materials were produced by the 'Department of Ideology' of the Prosecutor's Office. By examining the administrative records of the 1920's within this group, the process of how the 'Department of Ideology' was formed is clearly shown. As ideological movements for Korea's independence and revolution grew, execution of regulations was further expanded by the Prosecutor's Office. Since the mid-1920's, information on ideology had been separated from general information, was routinely collected heavily, and was considered more valuable than the general information. By the end of the 1920's, the term Ideology Prosecutor 思想係 檢事(meaning a prosecutor who specializes in ideology verification) and the named 'Department of Ideology'(思想部) emerged on the records.

This thesis has an intention to reorganize the topic of Ontology that has not unnoticed, investigating the symbolic signs of Zhuxi. The symbols in Ontology visualize in an anthropomorphic form or a form of animals that we can usually find in the nature. The visible symbols have characteristics of the dynamic rather than the stillness. The symbols of human and a horse have developed as different interpretations depending on the relative importance. The movement of stream symbolize the Movement of Daoti that manifests thorough all things in the Dao and have a structure of 'Ti-Xiang-Yong'. The Substance of Metaphysics embodies an action thorough 'Metaphysics' or 'with Metaphysics'. Accordingly, 'a stream' symbolizes 'the Movement of Daoti' in that it manifests the form of Daoti makes body. A kite and a fish symbolize the form of a kite flies up into the sky and the shape of a fish plays in the pond. These not only represent an outlook on the world, but also symbolize the stage of the Movement of Daoti. 'Human', 'a stream', 'a kite' and 'a fish' include activeness, domination, dynamics, manifestation, visibility, naturalness.

Modern Neo-Confucianism was formed as a school by solving the modern problems in China through accepting western philosophies with Chinese basic philosophies since New Cultural Movement. Marxism, Liberalism, and Modern Neo-Confucianism are called three representatives of Chinese modern philosophies. Since the People's Republic of China was founded in 1949, Modern Neo-Confucianists have tried to keep their philosophy and cultural conservatism in Hong Kong and Taiwan. Modern Neo-Confucianism which had been prohibited before 1978 was brought again to people's attention in the middle of 1980s by their active lectures and writings. Furthermore, the study on Modern Neo-Confucianism was supported by the Chinese government in 1987. China was trying to find the way to enhance Chinese tradition and to develop China to a modern society at the same time through the study on Modern Neo-Confucianism. The purpose of Modern Neo-Confucianism is to keep Chinese tradition which was broken off, to develop China to a modern society, to control the problems caused by capitalism socially, and ultimately to strengthen socialism in China in the political aspect. The study on Modern Neo-Confucianism in the 1980s focused on introducing, organizing, and understanding Modern Neo-Confucianism as its early stage. This study was led by Marxists with their methods and viewpoints. Even though the acceptance and understanding of Modern Neo-Confucianism was limited in a short period, the study on Modern Neo-Confucianism in the 1980s propagated Modern Neo-Confucianism. Modern Neo-Confucianism also played an important role to grow the argument about the critical succession of Chinese tradition and to reconsider the fact that modernization does not mean only westernization.
