This study attempts to grasp the correlation between the image of bridges and bridge landscapes with their surroundings during day and nighttime viewing, and to understand the psychological influence of nighttime lighting through quantitative analysis. In addition, it presents a design to construct bridges in order to increase viewers enjoyment of bridge landscapes lit at night. To attain this objective and contrive generalization of the results, this paper selects 8 of 9 bridges with lightings in Seoul and excludes bridges constructed by 2004. The criteria for selection of the viewpoints is that each must be within easy reach of bridges, and must allow viewers to recognize surrounding landscape details both in daylight and at night. As well, the pictures of bridges are taken in the terraced land by the riverside. The study selects 16 pictures, judged to be of similar quality and angle, to establish the conditions of luminosity, color, definition and angle. The results are as follows. First, viewers preferences of night landscapes are higher than day landscapes due to the effect of lighting. By day, viewers preferred bridges with various structures such as cable-stayed bridges and arch bridges more than simple bridges like girder bridges. Viewers also indicated preferences for lightings which feature a unique color and which are harmonized with their surroundings. Second, components representing the images of bridge landscape are classified into three types, 'beauty', 'system' and 'agreeableness'. Third, the factors affecting preference are the shape of bridge by day and lighting at night. Esthetic appeal is the most important factor in visual preference so each bridges own esthetic appeal and surroundings must be considered. Thus, a complete plan must be created which considers safety, beauty and the local surroundings. In addition, when the lighting of a bridge is selected, the design of the bridge landscape must consider various lighting schemes to harmonize the upper and lower parts of the structure. At this point, the study reveals the basic elements of bridge planning in order to increase appreciation of the bridge landscape.

Climate change adaptation must be prepared, because the pattern of climate change in Korea is higher than the global average. In particular, it is estimated that Korea's economic loss due to climate change will reach 2,800 trillion won, and at least 300 trillion won will be needed for adaptation to climate change(KEI, 2011). Accurate climate change forecasts and impact forecasts are essential for efficient use of enormous climate change adaptation costs. For this climate change prediction and impact analysis, it is necessary to grasp not only the global average concentration but also the inhomogeneity of the greenhouse gas concentration which appears in each region. In this study, we analyze the feasibility of developing a greenhouse gas observation satellite, which is a cause of climate change, and present a development plan for a low orbit environmental satellite by examining the current status of the operation of the greenhouse gas observation satellite. The GHG monitoring satellite is expected to expand the scope of environmental monitoring by water/soil/ecology in addition to climate change, along with weather/agriculture/soil observation satellites.

The purpose on this study is to grasp the clothing habits and problems of the Chinese-Koreans in Yanbian, China through the fact-finding survey about the clothing habits for the Chinese-Koreans in Yanbian, China who have frequent exchanges with the North Korea and have relatively similar home culture preparing for the unification of North and South Korea, also it is to make the basic data for improving their qualities of life. As for the method of study, it centered on the investigation by the questionnaire on the spot and it referred to the data like domestic and abroad literature, field observation, interview and internet, etc. as a reference. Also it centered on the girl college students and the housewives in Yangil City as an object of research. Accordingly, the result of this study is as follows. The Yanbian is the largest Chinese-Koreans group of people in the China. The economic environment in Yanbian is in the middle of the whole China. With the open-economy of China and the contact with the foreign culture, especially with Korea, the 1960s and 1990s coexist in. The Chinese-Koreans in Yangil spend about 1,425 CNY as clothing expenses averages a year, and the estimated value of holding amount of clothing is about 27 suits. They recognize the clothing made in Korea as high-quality and high-price of high-quality articles. They have high interest in the Korean fashion as the younger generation. They prefer to modern, active, refined and mature atmosphere in the clothing atmosphere, but they still do not reach to the level yet in actual. They generally have strong tendency with the preference of black color or dark color because they have small holding amount. The field materials of fiber did not become high-quality articles because they hold in the level of 1960s in Korea. So, the color level of Chinese-Koreans in Yanbian is still low.

The purpose of this study was to examine the effect of student-led assessment on achievement emotions and science concept understanding in middle school science classes. For this purpose, 4 of the 7 classes in the third grade of mid- dle school in small and medium-sized cities were selected as the experimental group and conducted student-led assessment, while the comparative group (3 classes) conducted teacher-led assessment. The student-led assessment consisted of 4 stages in which learners took initiative to set learning goals and develop assessment criteria, conduct self assessment and peer assess- ment, and carry out seven assessment activities. Student-led assessment was effective in improving positive achievement emotions and relieving negative achievement emotions and increasing students' science concept understanding in middle school students. Students perform student-led assessment, grasp their reach, and repeatedly go through reflective thinking to compensate for deficiencies in the learning process. Therefore, student-led assessment can be used as a tool to increase science concept understanding by continuously checking the level of science concept understanding.

The car-dependent traffic system based on highly advanced industrialization and economic growth causes various urban problems including traffic jams, energy consumption, air pollution, noise, car accidents and other issues. Particularly in urban areas, air pollution from motor vehicles is worse than pollution from past industrialization. In this study, therefore, the authors grasped car exhaust reduction effects by using microsimulation and those traffic policies that could make cars flow smoothly, reducing the air pollution in urban areas through analysis on profitability. As a result, the weekday-based car using system has been found most effective as it does not need investment cost. However, this system may be socially unacceptable, as it requires the government to change driver behavior. Therefore, the government needs to first reach a consensus with the citizens regarding this system. This system will also be effective with other alternatives. As a follow-up study, the authors will research citizens' perceived impacts of car exhaust on air pollution through a study on preference and grasp the possibility of applying these study results to real traffic policies.

Qi. in ancient east Asian Philosophy and medicine, was the quintessential concept symbolizing material orgin of the world. It was considered as the original matter of the world, and the genesis, development and extinction of everything in heaven and earth was explained through the movement of Qi. Despite its importance, the interpretation of Qi has brought about various bifurcations in the history of Oriental medicine. It is comprehended either as ideal concept, or as actual entity. Also, there exists synthetic idea of considering both sides of Qi. These ideas results from obscure understanding based on textual interpretation apart from actual experince. When experincing Qi through discipline, however, man can understand Qi concretly and actually and even grasp the explanation of the cosmos and life. One problem of Qi discipline was that it couldn't ascend the stage of subjective experience. Now, with the method of 'Hanalmomjit'. a developed form of zifadonggong(自發動功), I could reach coherent results to offer the foundation of objective understanding of Qi. The testees, disciples of Hanalmomjit, could express the characters of herbs in their Qigong actions, and the expression was meaningful and coherent to be considered as expressing the effects described in the classics of herbalogy. This result comes from the capacity of grasping external Qi-status, not only expressing the internal communication of jingluo(經絡) in Hanalmomjit.

Park, Se-dang criticized or accepted Zhuxi's annotation with his own way of understanding Confucian classics. His way of understanding Zhuxi can explain through the motive of writing his book, sabyeonrok and his basic view of scripture interpretation in the book. He thought one can achieve learning from lower to upper level. That means it is good for one to study from text easy to reach and attain, grasp. But if one begin to study from text or contents hard to understand, that will make to lose the proper way or province to the value of learning. This is what Park, Se-dang's basic point of interpreting Confucian classics, called 'learning from lower to upper level.' Park, Se-dang gave high praise Cheng Hao and Cheng Yi and Zhuxi who recreated confucianism into world from darkness. He thought Cheng-Zhu school corrected confucian's ways of learning went wrong from Chinese Han. So we need to reconsider the assessment of his view as anti?post-Zhuxi. He also thought there were a lot of way to understand Confucian classics. He insisted Zhuxi's way of annotating Confucian classics was one of them, and so as his. He understood Zhuxi's thought in this way of thinking and his academic method of 'learning from lower to upper level.' Therefore to interpretate Confucian classics new way he criticised or accepted Zhuxi's way of annotating scripture though his own way of understanding Confucian classics and academic method of 'learning from lower to upper level.'

Oriental Medicine has long been centered around Qi[vital force], hence adopting Qigong and the art of regimen for training the body and relaxing the mind so as to prevent and heal illness. It has not been such a long time since Qigong method had been performed and spot-lighted out of numerous methods in Oriental Medicine. In China and Korea alone, diverse cases and papers are published, only revealing so many steps toward the establishment of diachronic description, theoretical foundation, and clinical practice. Historical approach is an essential part of recognizing a subject. When you step along its path and comprehend what it were, you can also grasp what it is and what it will be. Establishment of Qigong history is also vital to research Qigong in theory and practice. Generally, Qigong was transmitted from China to Korea, whereas the opposite explanation, that it originated from Korean Taoism, is supported by the minority based on certain texts concerning ancient history. In this paper, I support the theory of Korean originality based on the following grounds: First, the location of Qi and Van, the motherland of Chinese Taoism provides a strong evidence that Korean tradition had been absorbed by them and formed the tradition of mystic hermits(shenxian). Second, Guangchengzi, the originator of mystic hermits, is from Dongyi tribe according to Cheonghakjib. Third, the myth of Dangun has pure form of unique Korean folklore possessing the distinctive feature of mystic hermits tradition, uninfluenced by Chinese Taoism. Fourth, in ideographical aspect, the character 'xian(仙)', was invented as the Korean concept of mystic hermits[xian] was flowed in to China. Moreover, There is high probability that it was based on the concept of mystic hermits shown in the myth of Dangun in Its original formation. Fifth, considering the relation between wild ginseng and the tradition of mystic hermits, that tradition can be formed very naturally in Korean area. Sixth, the analogical similarity between archetype of Korean tradition and Taoistic trilogy, the foundational idea of the tradition, gives genealogical basis to its origin. Seventh, the tradition of mystic hermits and Shamanism, which constitues the prototype of Korean mind as an original religious tradition, are undiscernible in their root In Conclusion, We can reach the idea that the origin of Qigong derives from Korean tradition, not that of China. The tradition of mystic hermits was transformed to ego-centric seclusionism when it faced the anarchy of Warring states period in China, whereas it was developed into humane proriety and worship of Heaven base on the programme of 'universal fraternity in pursuit of interst for man'. In prospect, it is highly required to develop and interpret traditional discipline methods in Korea so as to utilize them for clinical Qigong in practice.

Background : Clinical practice guidelines define "systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances" and help to improve patient care. The purpose of this study is to develop a clinical practice guideline for the most effective diagnoses and treatments of benign prostatic hyperplasia based on patient preference and clinical need. Methods : For this research project, extensive literature searches (208 articles) were conducted. As well, critical reviews and syntheses (meta-analysis) were used to evaluate empirical evidence and significant outcomes of the BPH literature. Questionnaires about clinical practice for BPH patients were distributed and consensus meetings were undertaken to grasp variations in clinical practice and to reach agreement on the guideline's development. The guideline was promoted under the sponsorship of the Korean Medical Association and the Korean urological Cancer. Society. For the task, the Benign Prostatic Hyperplasia Guideline Panel was composed of multidisciplinary experts in the field. Results : BPH is a disease that affects a patient's quality of life. This Clinical Practice Guideline was developed for the typical man over age 50 with symptoms of prostatism, but with no significant medical morbidities such as diabetes or other known causes of voiding dysfunction, such as urethral stricture or neurogenic bladder. The guidelines detail the relative benefits and obstacles associated with all diagnostic and treatment approaches, including watchful waiting. Conclusion : This guideline provides a cornerstone for our medical association. It represents the most current scientific knowledge regarding the development, diagnosis, and treatment of BPH. It will be revised and updated as needed.
