The purpose of this study is to estimate deterioration factors and weighting factors in pipe network which each local self-governments takes rehabilitation and replacement work present time. Deterioration factors in pipe network are able to effected of specific province or location related with water supply. Most of water supply pipes are laid under the ground, it is hard to quantify deterioration degree of water system. Moreover, the timing and economic limitation and insufficient information on the spot survey gives a difficulty to look over how old water supply system is. Accordingly, this study collects and analyses five data as the laying environment, visual analysis, analysis of soil contents, analysis of pipe material, and questionary survey data in water pipe of A city. The deterioration factor estimates 14 factors with excavation and experimental analysis and 9 factors without excavation and experimental analysis. Also, the weighting factors are estimated by using the multiple linear regressions and the linear programming. The estimated deterioration factor and weighting results are compared the analysis result of visual, pipe material, and soil contents with the Probabilistic Neural Network Model. Consequently, the model results of estimated 9 factors in this study and 14 factors show the 1-2% difference. The result show that the proposed model could be used to decide the deterioration condition of pipe line with real excavation and experimental analysis.

Light is a carrier to show the shape of object and space. But in a civilized community. We are using more many "artificial light" rather than "natural light" and ignoring variety and beauty of natural light. And mostly spaces are used in favor of function and concept. The using light of spaces is treated as an aesthetic value beyond a practical role. Because it plays only roles of lighting apparatus and heating. The aim of this study is to suggest an way of using light in the field of architecture to get the aesthetic value of light in places. Recently lots of traditional crafts museums which is designed of closed space has forced to put people off attraction of the crafts. So to solve this problem we try and plan to design exhibition of traditional crafts that is adopted a concept of light to use for open space. As the result of this study, the methods of using light as the architectural tool are concentrating, penetrating, filtering and reflecting. Therefore working with the idea, we are able to make special equipment to meet conditions of traditional crafts exhibition and ultimately obtain an artistic value of light in exhibition spaces.

The history of naming as Military Arts originated in about the 2nd century when the competition had been embodied and the classical scholars had trained themselves in the Military Arts basically, and in the Koguryo Dynasty when the Military Arts had been educated in the Tae-hak Institute where Confucianism had been taught. The thought of Korean Military Arts is to accomplish the completion of character which possesses both "courtesy" and "morality" through cultivating one's moral sense. The thought of Military Arts in the Kochosun Dynasty was "Morality through wisdom" where the goal of morality or discipline existed in maintaining the ethical public order of the nation. The Military Arts of Koryo Dynasty was based on the Confucian ideology respecting loyalty, filial piety and righteousness And in the Koryo Dynasty, "Su-bak", "Keung-sa" and "Kyuk-gu" were very popular Especially, "Su-bak" was most popular as an individual Military Arts and became the origin of spirit of our nationality. The Military Arts of Yi Dynasty has a thought of Military Arts which aimed at wiping out the fighting under the six kinds of virtue such as filial piety, loyalty, courtesy, sincerity, reverence and holiness. With these influences of thought of the Korean Military Arts, Taekwondo, the Korean art of self-defense, which is based on the spirit of Military Arts of Su-bak and Taek-gyun resulted. The remains which can prove the historic fact about the birth of Taekwondo of our nation are found in many spots. One of them is wall paintings in the tomb of a crown prince which can be found at the ancient tombs of Koguryo Gak-jo-chong and Sam-sil-chong, etc. in the Kug-nae-song which was the capital of Koguryo that had placed at Tong-man, Jip-an-hyun, Tong-hwa-song of Manchuria in current China. These wall paintings still show the original form of Taekwondo. After Taekwondo occurred, it was called as Taek-gyun, Tok-go-ri, Taek-go-ni, Su-bak, Tae-kyun, Tak-grun, etc. and changed into Taekwondo until now. Kogurye, Baekje and Silla in the Three Kingdom Period strugg1ed with one another for territorial dispute for enlarging the sphere of influence and unification of the nations internally. And externally, the sports activities centered on the Military Arts to promote the spiritual awakening of national consciousness against the foreign enemy were done actively. Therefore, this study selected the approach by means of the idea for the changing process of phenomena laying great emphasis on Taek-gyun, Su-bak and Taekwondo to infer how the spiritual function and principle of Taekwondo of our nation has been changed emphasizing the thought of Military Arts.

In domestic sewer rehabilitation works, the numerical weighting based on number of sewer defect is used to determine the propriety of rehabilitation order. In case of the decision standard in each defect contents of inside and outside of the country, the weight for determining sewer rehabilitation order is composed of several distribution of marks, not considering the weight in each sewer defects. In this study, the fifteen defect contents are determined suitable for domestic situation based on the sewer defect data of inside and outside of the country. Also, we select persons in charge of the business to calculate the detail weight and pose questions about important level of each sewer defect contents. The results of using Delphi method which is a question survey method apply the AHP and calculate the weight in each sewer defect. The appropriate marks matrix of sixteen sewer defects is made for laying precise decision standard of sewer condition through the result of analysis. The marks matrix of sixteen sewer defects can solve the complicated decision making problems of sewer rehabilitation works.

體育의 藝術的 側面에 關한 硏究

The scientific advances in physical education have not always been positive. One example is that scientific methodlogies have disregarded the embodied dimension of knowing which is the core of physical education. The values and meanings inherent in physical activity are realized in its artistic base. The purpose of this study is to justify the field of physical education in the intellectual community as art rather than science. The elements of the problem, in the process of this study, can be summed up in the following questions; 1. Does scientific knowledge itself constitute a full understanding of physical education? 2. What is the theoretical basis for the claim of physical education in the intellectual community as uniquely valuable? 3. What is the field which has regarded the human body as the knowing subject, physical activity as the process of knowing itself? 4. What is the theoretical basis for the claim of activities in physical education as not being artful? 5. what is the theoretical basis for the clain of activities in physical education as artful? A treatment of these inquiries follows; First, scientific knowledge doesn't constitute a full understanding of physical education. Although scientific methodologies have contributer remarkably to the expansion of knowledge in physical education as an academic discipline, they have disregarded the embodied dimension of knowing which is the core of physical education. Second, the values inherent in physical education can be found in the human potential for embodied knowing. And embodied knowing founded upon the epistemology of existential phenomenology as it's theoretical basis. Edmunt Husserl and Merleau-Ponty, existential phenomenologists, regarded the human body as the subject of knowing and physical activity as the process of knowing itself. Third, the field which has regarded the human body as the subject of knowing and physical activity as the process, is art. The subject and object in artful knowing become intergrated. However, body sensitivity which has been regarded as doxa, plays a central role in artful knowing. Fourth, the arguments which precludes sport from being an art have been summed up as follows: (1) Sport in general, is practical rather than aesthetic. (2) Sport may be aesthetic, but it is not artistic. A critical examination of these claims it made to highlight the converse. As a result, it is found that both claims may have logically valid points, but they are invalid in sport perfomer's experiences. These claims reveal, in themselves, the limits of logical analysis concerning subject matter such as play, sport and art. Fifth, the argument for sport as pontential art is reinforced by Metheny and Ellfelt(from a theoretical sphere) and Kleinman(from a methodological angle). It is also suggested that understanding sport can be realized by the embodied mode of knowing. The Eastern martial arts have been discussed as a prototypical movement artform. In such a holistic approach we can rediscover the artistic dimension of sport experience that has been overshadowed by the excessive goal-centeredness of contemporary sport, such as winning-at-all-cost.

Building integrated photovoltaic(BiPV)systems can from a cohesive design, construction, and energy solution for the built environment. The benefits of building integration are well documented and are gaining significant public recognition and government support. PV cells, however, convert only a small portion of the incoming isolation in to electricity. The rest is either reflected or lost in the form of sensible heat and light. In order to judge of the Integration capability to the BIPV system, energy efficiency, capacity and integration capability is studied by considering the production quantity of electric power and U-value of PV system.

고순도 Ge(HPGe) 검출장치를 사용한 현장측정을 통하여 지각방사선에 대한 핵분광학적 연구를 수행하였는바 지각방사선장의 핵분광학적 특성차이를 규명하기 위하여 지면의 자연방사성 핵종분포가 대표적 전형인 충남대학교 캠퍼스내 미경작 개활지 잔디밭과, 우라늄 함량이 높은 곳으로 알려진 괴산군 덕평리 지역 등 특이한 두 지역을 측정지점으로 선택하였다. 환산선량의 비교확인을 위하여 HPGe 분광측정은 3″ø×3″원통형 NaI(T1) 섬광검출기에 의한 분광측정과 동시에 수행하였으며 본 연구에 사용된 HPGe 검출기에 대한 스펙트럼-선량율 환산인자 G(E)는 감마선속이 검출기 축에 수직 입사하는 것으로 가정하고 Monte Carlo 방법으로 씨뮬레이션한 감응스펙트럼들을 사용하여 산출하였다. 이 G(E)를 사용하여 산출된 선량율(D˙_Ge)은, 이미 기준기급 전리함과의 비교 교정을 통하여 스펙트럼-선량 환산체계가 확립된 바 있는 NaI(T1) 검출기로 구한 선량율(D˙_NaI)과 만족스러운 일치를 보였으며 D˙_Ge와 D˙_NaI 사이의 상관계수는 +0.9988, 회귀 방정식의 기울기는 1.001을 나타내었다. 측정한 스펙트럼에서는 미미한 크기의 ^137Cs 감마선 피크가 확인되었으나 1960년대에 수행되었던 대기권 핵실험의 영향이나 Chernobyl 원전사고의 영향은 관측되지 않았다. Study of terrestrial gamma-rays was carried out by means of in-situ spectrometry using high purity germanium (HPGe) detector system. Two distinguishable fields of measurements, namely, uncultivated flat lawns in CNU campus where the distribution of natural radionuclides in the ground in known to be quite typical and well-known uranium rich area of Dukpyung-ri in Gwoesan-kun were selected in order to specify the difference in spectrometric characteristics of the fields. In-situ HPGe spectromety was accompanied by scintillation spectrometry with 3″ø×3″cylindrical NaI(T1) detector for comparative confirmation of derived dose rates from the spectra measured. Spectrum-dose rate conversion operator, G(E), of our particular HPGe detector was calculated using response spectra simulated by Monte Carlo method with an assumption of gamma-ray beams incident vertically to the detector axis. Resultant dose rates (D˙_Ge) showed satisfactory agreement with those obtained by NaI(T1) spectrometry and corresponding G(E) operation (D˙_NaI) of which system has been well-established through intercalibration with a reference ion chamber. Correlation coefficient and the slope of regression equation between D˙_Ge and D˙_NaI came out to be +0.9988 and 1.001, respectively. Though traceable height of ^137Cs gamma-ray peak was identified on the field spectrum, ground contamination of fission products released from atmospheric nuclear test performed in 1960s and possibly from Chernobyl accident was not observed as of today.
