The purpose of this study was to seek the spatial organization and prototype landscape through literature reviews, historical evidences, and field surveys for Donggwanwangmyo(東關王廟) shrine in Seoul. The results were as follows : First, the basic layout of the main buildings in Donggwanwangmyo which is the remains influenced by China had bilateral symmetry on the central axis between the north and south. Second, the Chinese forms and features were found at Jeong-jeon and middle gate in Donggwanwangmyo, and the symbolic elements of royal authority was also found in each space of Donggwanwangmyo. Third, spatial organization was classified as the entrance and the ritual area, and the entrance area was maintained by administrators and was used as the place of ritual ceremony preparation. Fourth, the original form of Donggwanwangmyo had been damaged due to the project for making urban park in the 1970s. The most of the existing trees and shrubs which are not suitable to the shrine should be removed to recover the original landscape of Donggwanwangmyo and chui-byoung(翠屛), pond, landscape facilities also needed to be restored. Fifth, Donggwanwangmyo needed to reorganize the pious atmosphere to recover of the shrine environment, and needed to be reclassified as historical site. Finally, some criticizes that Donggwanwangmyo is the result of Toadyism, but Donggwanwangmyo can be used as the valuable tourism resource through the awareness that Donggwanwangmyo was built under the situation of Joseon Dynasty, and organization and understanding that Donggwanwangmyo is a symbolic remains for the exchange between Korea and China.

This study was performed with an aim to examine the inner thoughts of Muso Soseki through his works. In this study, we reviewed currently existing Mus$\bar{o}$ Soseki. Works in which his idea or intention behind his works are to be understood in terms of landscaping science or religious perspective. Targeting his best representative works of temple gardens such as Jochou-ji, Eiho-ji, Zuisen-ji, Tenryu-ji, it was sought his view of gardening and technique of garden making. Those temples, selected as target of this study, have significance as a places to have started his learning till matured of his thought into his gardening works. What we need to concentrate and think about regarding the works of Muso is the fact that we are to be impressed upon just looking at his works. The study result indicates that Muso not only symbolized his various mastered ideas & philosophies into spatial configuration into the garden based on Zen Buddhism idea, but also accomplished the Sabi-gardening beauty. Through his writing "Mongjoongmundap(夢中問答)" that is created using his core thoughts, his works can be understood better. This study has significance in that the idea. It could be understood that Muso's work is rooted in the basic idea of three ideas. The first of it is Zen philosophy being indicated in his configuration of gardening such as Zen meditation Stone, cave, chamdo etc. The second of it is shown as the merciful heart of Sangguboje(上求普提), Hahwajoongsaeng(下化衆生), being indicated in his configuration of gardening such as the pond And finally, there appears the Tao idea. Taoist thought has become of where the background space.

Collaborative filtering systems have problems involving sparsity and the provision of recommendations by making correlations between only two users' preferences. These systems recommend items based only on the preferences without taking in to account the contents of the items. As a result, the accuracy of recommendations depends on the data from user-rated items. When users rate items, it can be expected that not all users ran do so earnestly. This brings down the accuracy of recommendations. This paper proposes a collaborative recommendation method for extracting typical group preferences using user-item matrix optimization and user profiles in collaborative tittering systems. The method excludes unproven users by using entropy based on data from user-rated items and groups users into clusters after generating user profiles, and then extracts typical group preferences. The proposed method generates collaborative user profiles by using association word mining to reflect contents as well as preferences of items and groups users into clusters based on the profiles by using the vector space model and the K-means algorithm. To compensate for the shortcoming of providing recommendations using correlations between only two user preferences, the proposed method extracts typical preferences of groups using the entropy theory The typical preferences are extracted by combining user entropies with item preferences. The recommender system using typical group preferences solves the problem caused by recommendations based on preferences rated incorrectly by users and reduces time for retrieving the most similar users in groups.

In the early 20th century, Japan built theaters to take possession of colonial culture while establishing the Imperial University, libraries, and museums to accumulate and spread the knowledge of "imperial" Japan. Many different genres made a hit in theaters including theatrical troupes, theatrical companies, and motion pictures. One of the various features of expositions was "spectacles" or unusual events. They were integrated with a national festival in celebration of "5th anniversary of political commencement." In 1915, the longest hit series in Keijo (Seoul) was the dance performance by professional Japanese beauties and entertainers, whose songs delivered the legitimacy of governance. This study focused on the performance in the space of "cultural" spread called theaters, thus examining the "imperial" cultural waves they were in charge of. The study also focused on the tensional relations of Hierarchie along those cultural borders. The performance at the theater Engeikan(演芸館) in 1915 was especially an epoch-making event in the Japanese theatrical community of Keijo (Seoul): first, it marked the emergence of large-scale performance hall called Engeikan(演芸館); secondly, the performance kept its ongoing, stable streak for about 50 days; and it led to the appearance of leading troupes including Geijutuza(芸術座), which put on a show in Keijo (Seoul) in November, 1915. The study examined the issues of theater Engeikan(演芸館) performance in 1915 involving the art company, performance genre, and audience composition, showed that there was the coexistence of entertainment and governance through cultural ruling while securing amusement and entertainment, and found it was accompanied by the organized operation of "Keijo Sponsorship Council（京城協贊會）" which brought together the cultural capabilities of Japanese people living in Joseon. The performance at theater Engeikan(演芸館) in Keijo (Seoul) in 1915 fully reflected the issues involving the tensional relations between different artistic genres, the competing relations between the subjects of performance, and the cultural power.

This study was carried out to understand the national and regional distribution of the biomass resources produced in Korea annually via establishing database (DB) and distribution maps of biomass resources data including as livestock manures, food wastes and agricultural by-product. The information of the annual production of each biomass resources was obtained from Ministry for Food, Agriculture, Forestry and Fisheries (MIFAFF), Ministry of Environment (MOE) and National Statistical Office (NSO). Based on biomass resources data, we established database architecture table about livestock manures and food wastes. The distribution maps for the total amount of manures produced from each livestock animal were built up in both national and regional scales and used for analysis of the space-based and time-based distribution of the manure resources. Distribution maps for food wastes and agricultural by-product were also produced, respectively. It was shown that the analysis through resource mapping can be used to identify the sources of collectable biomass feasibly determining suitable region for establishment of a biomass-energy production. The biomass distribution maps graphically provide the information regarding biomass resources to policy-makers, farmers, general users and it was expected to be utilized for policy-making of environmental-friendly agriculture and bio-energy.

Forest in the our country is in the age that needs positive operation in order to foster economical forest. Multiple operations for making valuable forest should be conducted steadily and timely from afforestation to harvesting. In order to execute these kinds of forest operations, the construction of skid trail network that can be effectively used as a pathway for forestry machine and working space is necessary. To investigate facility effect of skid trail network, we executed the location of skid trail network through centroid method by GIS for 50ha of harvesting workplace in mechanized model forest located in Hongcheon, Gangwon Province. As a result of this research, skid trail density in this area changed from 79m/ha with current method to 42m/ha with improved method. It appeared that skid trail density with improved method is nearly half of current method even though the cutting area is the same as the current cutting area. Also, skidding distance changed from 117m with current method to 57m with improved method. It appears that skidding distance with improved method is nearly half of current method even though cutting area was enlarged in adjacent tending cutting area.

Since Schwab mentioned the Fourth Industrial Revolution at the World Economic Forum Annual Meeting 2016, discussions have been ongoing about it and the future society. The Fourth Industrial Revolution exceeds the development of technology and influences society, culture, and lifestyle. Moreover, in the face of the COVID-19 crisis, society continues to experience and realize the era of the Fourth Industrial Revolution. Although we hope that this era will surely improve human life, we are also concerned about human alienation and social and economic polarization that may emerge as a consequence. How, then, does Christianity contribute to the public space and set the direction for education in this day and age? This study focused on the role of Christianity and the direction of education during the Fourth Industrial Revolution. First, I examine problems in terms of the inner and outer aspects of individuals and communities that may occur during the Fourth Industrial Revolution through the perspectives of Mitchell, a psychologist, Bellah, a sociologist, McGrath, a theologian, and Bostrom, a philosopher. Through their theories, we can view the lives of individuals in the real, virtual, and transcendental worlds of this era. I find that Christianity can provide a transcendent norm in this world, give meaning to life, and change people and the world. Therefore, I suggest the creation and expression of symbols as a direction for education. For this form of education, I recommend five steps, namely, observing, entering, discovering, participating, and making symbols. In this manner, people can represent the kingdom of God in the real world.

Securing a stable residential location is one of the most important decisions that must be made in the modern society. On this matter, both individuals and their families must decide on where to live after taking into consideration various analyses. Contributing attributes in the selection of our dwelling place are crucial. In this research, influencing variables were derived from the intention to move by focusing on the characteristics of the household and traffic conditions, while implications were suggested through a comparison of urban characteristics. Suwon was selected as the case study. The result of the analysis showed the city of Suwon has longer communal satisfaction, relies on self-sufficiency, and is conscious of parking regulation. Preferences for rental housing, having infants and elementary school kids, high savings, and commuter convenience in Suwon and Gyeonggi-do ranked higher in the hierarchy of the intention to move. Compared to Gyeonggi-do, Suwon was influenced by commuters in the city and parking regulation-related variables. Meanwhile, Gyeonggi-do was affected by the lack of public transportation facilities and traffic congestion. Suwon, on the other hand, has a high share of passenger car ownership, so it seems that the psychological stability of parking space is significant. This research will contribute in the policy-making of Suwon, especially on the subject of migration prediction of citizens and real estate location selection, through analyses of variables related to the intention to move to a new residence.

Hyochang Park was the royal tomb of the Joseon Dynasty, where were the tombs of Prince Munhyo and his birth mother Ui-bin Seong, king Soonjo's concubine Sook-Ui Park and Youngon princess by a concubine. It was upgraded from Hyochang tomb to Hyochangwon at King Gojong. The Japanese imperialism destroyed Hyochangwon and made it into a park, also moved to Seosamneung in 1944. After returning from Chongqing after liberation, Kimgu made the independence movement tomb in the empty space of Hyochang Park. There were 3 martyr's tomb, provisional government figure tomb. Kimgu himself was buried in Hyochang Park after his death in 1949. During the regime of Rhee Seung-man and Park Jeong-hee, there was a constant attempt to change the identity of Hyochang Park, where independence activists were buried. Hyochang Stadium, Wonhyo buddhist priest's Statue and North Korean Anti-Communist Tower were established. After democratization in 1987, the independence activist tomb of Hyochang Park began to gain meaning again. The 6th Republic succeeded the provisional government in the Constitution, also the national cemetery and independent park of Hyochang Park were attempted but the social consensus could not be achieved. This study focuses on the historical middle layer and symbolism of Hyochang Park and aims to contribute to social consensus on the identity of Hyochang Park by making a storytelling on the theme of 'Independence Road'.

The scientific, economical and industrial values of the Moon have been increased, as massive ice-water and rare resource were founded from the lunar exploration missions. Korea and other major space agencies in the world are competitively developing the ISRU (In Situ Resource Utilization) technology to secure future lunar resource as well as to construct the lunar base. To prepare for the lunar construction, it is essential to develop the rover based construction spatial information technology to provide a decision-making aided information during the lunar construction process. Thus, this research presented the construction spatial information technology based upon rover's camera system. Specifically, the conceptual design of rover based camera system was designed for acquisition of a rover's navigation image, and lunar terrain and construction images around the rover. The reference architecture of the rover operation system was designed for computation of the lunar construction spatial information. Also, rover's localization and terrain reconstruction methods were introduced considering the characteristics of lunar surface environments. It is necessary to test and validate the conceptual design of the construction spatial information technology. Thus, in the future study, the developed rover and rover operation system will be applied to the lunar terrestrial analogue site for further improvements.
