The needs for Light Railroad Transit(LRT) have been increased due to the heavy traffic congestions in large cities like Seoul, Korea. Korean government is seeking the LRT system development (including planning, designing, construction, and maintenance and operations) in terms of public-private-partnership (PPP). At the private sector side, it is crucial to estimate the life cycle cost (LCC) to project the cash flow during the O&M period. Since the most construction and O&M cost of LRT project is at the bridge construction, a cost analysis model and a cost breakdown structures (CBS) on LRT bridges are discussed through in depth literature reviews. Construction and maintenance cost of bridges are collected and analyzed. LCC is analyzed by types of bridge superstructures and historical data of repair and rehabilitation (R&R) is investigated. There have been scarce number of LCC analysis on railway bridges. This research delivers a well-defined CBS and maintenance cost data, which will be a great benefit to the systematic maintenance strategy development for railroad bridges.

This study is an attempt to grasp the fundamental characteristics and core structures of Bibliodrama, which has recently received a lot of attention in various fields including Christian education. Bibliodrama is a guided form of process-oriented staging of biblical texts in groups with the aim of mutually opening up the text and the biography of the participants in the implementation of holistic encounters (H. Aldebert). In the background of the birth of Bibliodrama can be found the hermeneutical efforts of the biblical scholar Walter Wink who sentenced the bankruptcy of historical criticism. He laid the biblical interpretative foundation for Bibliodrama which combines Bible and body. German theologian Gerhard Marcel Martin had a new experience of seeing the Bible through body activity during his life in New York, and based on that experience he began to work on the Bibliodrama. And the New Testament scholar Tim Schramm, who focused on the TCI (themecentered interaction) movement, found the optimal methodology to embody the interaction of biblical studies in Bibliodrama. On the other hand, Peter Pitzele, who wanted to realize the Bibliodrama in the tradition of Midrash, has developed a new type of Bibliodrama (Bibliolog) that is different from the European Bibliodrama. When we put together the positions of the pioneers of Bibliodrama, it turns out that it has three fundamental characteristics: body, interaction, and the empty space of the Bible. The body refers to the personality of learners participating in the Bibliodrama. They are not passive participants, but voluntary and active participants. Interaction is realized through the dramatic way of Bibliodrama. Bibliodrama aims for a dynamic process in which hermeneutical interaction occurs. The empty space of the Bible, which Bibliodrama pays attention to, allows us to understand why the Bible is not a fixed word but a living word that is still heard today. In order to understand the Bible as the content of education, Bibliodrama liberates the text that is fixed in a literal way and gives life by paying attention to the empty space of the Bible and reading it slowly.

To establish a foundation to objectively interpret Chosun history, we construct people network of the Chosun dynasty. The network shows scale free network properties as if most social networks do. The people network is composed of 1,379 nodes and 3,874 links and its diameter is 14. To analysis of the network dynamics, whole network that is composed of 27 king networks were constructed by adding the first king, Taejo network to the second king, Jeongjong network and then continuously adding the next king networks. Interestingly, betweenness and closeness centralities were gradually decreased but stress centrality was drastically increased. These results indicate that information flow is gradually slowing and hub node position is more centrally oriented as growing the network. To elucidate key persons from the network, k-core and MCODE algorithms that can extract core or module structures from whole network were employed. It is a possible to obtain new insight and hidden information by analyzing network dynamics. Due to lack of the dynamic interacting data, there is a limit for network dynamic research. In spite of using concise data, this research provides us a possibility that annals of the Chosun dynasty are very useful historical data for analyzing network dynamics.

This thesis is research about the development and application of the panorama image in contemporary artwork, focusing on sculpture and installation. The samples of artworks are a selection of representatives from numerous examples of works that cannot be introduced without exceeding a reasonable scope of the thesis. A brief outline of the historical concepts of the perspective will describe the development of the panorama in itself. Some technical explanations and the practical use of the panorama with its link to 3-dimensional applications should bridge the explanation gap between the 2nd and 3rd dimensional usage of the panorama in contemporary artwork. Furthermore, some philosophical statements are proposed in the discussion. One of the main interests and initial motivation of this study was my personal believe that there is always a relationship between social philosophical values and the way a society sees or encounters visual structures. In other words the contemporary understanding of space and perspective is mirroring the actual zeitgeist and creates an exemplary visual aesthetics.

A traditional garden in Korea has diverse cultural, historical values, such as the then phases of the times, life phase, culture and art, etc. because it was developed on the basis of the harmony between nature and artificial structures. However, in reality, it's urgent to do efficient, continuous maintenance of traditional gardens which are being damaged and lost due to the problems like an owner's aging, inheritance, and lack of management, etc., especially in case of private property which was designated as a cultural property among such traditional gardens under the Cultural Properties Protection Law. Accordingly, this study conducted this research in a bid to use these research results as basic evidentiary materials for suggesting directivity in introduction of park planning of traditional gardens in folk houses in the near future by implementing the case investigation of transformation into public parks from traditional private gardens in Japan, which is putting the newly introduced park planning to efficient use, together with its systematic management, and the survey on domestic traditional gardens in folk houses status, as well as the hearing-based survey on a traditional gardens in folk houses owner's level of willingness to accept the introduction of parking planning. As a result, this study could confirm that in case of traditional gardens in Japan, they are mobilizing the revenue from admission fees for traditional gardens maintenance by incorporating the main entity of possession, and Japan is promoting transformation of traditional gardens into parks on the basis of use and preservation through the connection with local governments and research institutes. In addition, as a result of surveying domestic traditional gardens in folk houses, it was found that most of the garden owners had hardships in its management, and they were positive about systematic maintenance of gardens through park planning.

Recently, Korean medium-sized medical organizations require innovative strategies. Network-driven concerns in Korean medical organization have been a front burner issue to enhance economic and managerial efficiencies. Effective network-driven collaboration depends upon effective processes and economics strategies among medical providers group. From this motivation, we studied and provided the systems' theoretical background and networked hospital system structures. The aim of suggested research model in this paper is to overcome demerit of stand-alone medium-sized hospitals and analyze a system dynamics model to measure managerial performances. The developed system dynamics model is to quantify the effects of network strategy based on the historical financial data of real-life hospitals network experiences. The network effects are resulted in efficiencies and effectiveness enhancements in competitiveness through advertisement and effective education system. The simulations of system dynamics results can explain the improvement in financial outcome by joining in the network group. The network effects are shown more effective in dental hospital than other groups. In conclusion, it is expected that network effects have a critical influence of managerial, marketing, and medical collaboration performance for any type of medical hospitals.

Liquefaction is a significant threat to structures on loose saturated sandy soil deposits in the event of an earthquake, and can often cause catastrophic damage, economic loss, and loss of life. Nevertheless, the Korean peninsula has for a long time been recognized as a safe region with respect to the hazard of liquefaction, as the peninsula is located in a moderate seismicity region, and there have been no reports of liquefaction, with the exception of references in some historical documents. However, some earthquakes that have recently occurred in different parts of the world have led to liquefaction in non-plastic silty soils, a soil type that can be found in many of the western coastal areas of Korea. In this study, we first present procedures for evaluating the liquefaction potential, and calculate the liquefaction potential index (LPI) distribution at two western coastal sites using both piezocone penetration test (CPTu) data and standard penetration test (SPT) data. The LPI is computed by integrating liquefaction potential over a depth of 20m, and provides an estimate of liquefaction-related surface damage. In addition, we compared the LPI values obtained from CPTu and SPT, respectively. Our research found that the CRR values from CPTu were lower than those from the SPT, particularly in the range between 40 and 120 for the corrected tip resistance, (qc1N)CS, from the CPTu, or in the range of CRR less than 0.23, resulting in relatively high LPI values. Moreover, it was observed that the differences in the CRR between the two methods were relatively higher for soils with high fine contents.

The rainfall pattern analysis on time distribution characteristics of rainfall rates in important in determination of design flow for hydraulic structures, particularly in urban area drainage network system design. The historical data from about 400 storm samples during 31 years in Seoul have been used to investigate the time distribution of 5-minute rainfall in the warm season. Time distribution relations have been deveolped for heavy stroms over 20mm in total rainfall and represented by relation percentage of total storm rainfall to percentage of total storm time and grouping the data according to the quartile in which rainfall was heaviest. And also time distribution presented in probability terms to provide quantitative information on inter-strom variability. The resulted time distribution relations are applicable to construction of rainfall hyetograph of design storm for determination of design flow hydrograph and identification of rainfall pattern at given watershed area. They can be used in conjuction with informations on spatstorm models for hydrologic applications. It was found that second-quartile storms occurred most frequently and fourth-quartile storms most infrequently. The time distribution characteristics resulted in this study have been presented in graphic forms such as time distribution curves with probability in cumulative percent of storm-time and precipitation, and selected histograms for first, second, third, and fourth quartile stroms.

The present study is designed to examine categories and characteristics of the scenic sites depicted in the "Joseon MyungSeung SiSun(Collection of Poems on Joseon Dynasty Scenic Sites, 朝鮮名勝詩選)" written by Narushima Sakimura(成島鷺村) during the early period of the Japanese Colonization to introduce the scenic sites of the Korean Peninsula. Introduction and forewords are construed in order to define the purpose of the Collection, and thorough analysis are conducted on category, location, and distinct characteristics of approximately 1,700 scenic sites described in the body. From the study, it is identified that there are twice as many cultural landscapes introduced in the Collection than natural landscapes, and the most frequently introduced sites are historical Buddhist sites, pavilions, famous mountain in the respective order. Further, the study reveals that the Collection makes reference of the verses written by virtuous Korean scholars in order to broaden the significance of the scenic sites, and also that the Collection marks the time period when the new scenic sites with symbolic implications of the modern period at the turn of the Japanese colonial period are began to be introduced. Such new scenic sites include modern parks and commemorative structures, beaches, train stations, etc. Nevertheless, the scope of study presents limitation as its scope of analysis does not take the changing perceptions of people on scenic sites before and after the colonial period into consideration, and also further comparative analysis on other documentations made record on the scenic sites of the Korean Peninsula will need to be continued in the future studies.

This study examines the historical background of Goryeo and its relationship with Song and Yuan. In addition, it observes the shape of dress styles for the king, queen, officers, maids in waiting, and commoners after classifying them with a focus on the dress style of normal people appearing in Buddhist paintings. This study then investigates structures by tracing Goryeo's unique identity and its characteristic by a comparison and analysis of dressing style elements of Goryeo with Song and Yuan. The results shows that the Song's system was used exclusively for the dress style of the king and government officers of Goryeo after Goryeo's submission period by Yuan. There were no clear appearances of a Mongol style dress but only changes in head styles of cutting hair around the head and twisting the rest in a top down and long method. In addition, Song's style Bokgeon was shown by the king to his lower level officers. This was because the king and his officers of Yuan were in accordance with Song's system in officer's dress, hat and head style, armor, and horseback riding equipment. Second, there is doubt if they inherited a traditional form and style of the dress rather than followed the dress style of Yuan because the shape of Yuan's basic dress style Deel is very similar to the dress shape of early Buyeo people's Po in the $3^{rd}$ to $4^{th}$ centuries. Third, the shape of the Chaksu and Gung-go had been kept as it was in the dress style of ordinary men, and because the shape of the double collar had already appeared in the period of Samguk, which appeared in all classes of Yuan. There is no reason to adopt double collar shape that appeared. The general Pyeonbokpo of the country had to be influenced by Yuan. Forth, the dress style of queen and her maids in waiting were mentioned in documents; however, there was no shape of a dress like Boktag and Deel in the relics, which are the characteristic of Yuan's woman dress style. Fifth, the shape worn national style Yu and Sang had been kept in an ordinary woman's dress style; however, the two style system of high and lower class in Yuan's ordinary woman dress style appeared newly and is considered an influence of Goryeo.
