The "Silt Pond" is 180 hectares in size and contained ultra soft slurry-like soil varying between 3 to 20 meters in thickness. Reclamation works in the Silt Pond commenced in the mid of 1990s. A considerable amount of subsurface investigation inclusive of sampling, field vane and density logging tests were carried out prior to the reclamation of the Silt Pond. Since material in the Silt Pond is extremely soft, filling was done by spreading sand with high water content in thin and equal thickness lifts, allowing the stability of the slurry-like foundation. Despite the extreme care taken, failures occurred during the sand spreading phase. A large piece of high strength geotextile measuring $900m{\times}700m$ was placed to strengthen the slurry like soil foundation at locations where the ultra-soft soil was found to be exposed. Following the remedial works, the Silt Pond was again reclaimed by sand spreading up to +4.0m CD. The success of the reclamation was confirmed by marine CPT profiling.

This article aims to explain the significance and value of cartoons in the 1910s which were largely passed unnoticed in the preceding cartoon studies by scrutinizing cartoons published in Maeilsinbo in the 1910s. Until now, Korean cartoons in the 1910s has been neglected just because it were published in Maeilsinbo. However, this writing analyzed cartoons in this period on the base of the fact that the cartoons in the 1910s printed in Maeilsinbo diversified the horizon of the Korean cartoon. Cartoons in Maeilsinbo functioned as a bridge connecting cartoons published in Daehanminbo in 1909 reputed as a root of Korean cartoon and 1920s, the time when satirical cartoons and comics started being printed in newspapers. The characteristics of Maeilsinbo as a bulletin of government general and periodical characteristics that the agent of popular culture begun to move reside as multi layers in the cartoons in the 1910s. In this article, the process and the development of how cartoons published in Maeilsinbo. As pleasure became important in everyday life in Korea, cartoons were able to earn a portion in the newspaper. In the beginning, modern cartoon style seemed vague, but as time goes by, its own style gradually settled. Cartoons in this period were not fixed in specific section but various kinds of cartoons were developed during the time since works of Korean as well as Japanese cartoonists and illustrators were published. Among them, representative cartoons in Maeilsinbo were analyzed in this article under three categories: first, cartoons represented 'Choseon-ness' through scenes of daily life and customs concurrently contained a view of anti-civilization/enlightenment; second, cartoons represented the accumulation of wealth as valid from the view point of public interest; last, cartoons divided Koreans who suffered from hardships of life in Kyungsung and Japanese in Jingogae in order to divide space. In conclusion, Maeilsinbo disciplined the colonized, Koreans, and exposed the discourse of the colonial power via cartoon.

석탄으로부터 합성석유를 생산하는 상용기술을 도입하여 건설하고 이와 더불어 원천기술 개발을 위한 국산화 기술 개발을 병행하여 향후 고유가 시대를 대비한 국가 에너지 안보 확립과 국내 기술 개발의 가속화를 추구해야 할 필요성이 대두되고 있다. 본 타당성 조사는 3종류의 석탄(호주 Wyong탄, 인도네시아 NTC탄, 인도네시아 KBB탄)으로부터 가스화에 의하여 합성석유스를 생산하는 공정에 대한 타당성 조사(Feasibility Study, FS)를 Class 5(하한 -50~-20%, 상한 30~100%)의 정확도로 수행하는 것을 내용으로 하고 있다. 플랜트의 규모는 합성석유 기준으로 20,000배럴/일이다. 플랜트의 건설을 위해서 광양제철소 슬래그처리장 내 12만평 부지에 조성 중인 포스코 SNG 생산공장 부지의 일부를 사용하는 것을 기준으로 하였다. 일반적으로 석탄의 종류에 따라서 가스화기의 종류 및 성능이 결정된다. 본 타당성 조사 연구에서 선정된 3종류의 석탄의 조성, 발열량, 회분 함량 등의 특성을 고려하여 각각의 석탄에 적합한 현존하는 상용급 가스화기를 선정하였다. 해당 석탄이 가스화기 종류에 따라 적절한 전처리 과정(건조, 분쇄, 슬러리화)을 거친 후 가스화기에 공급되는 것을 가정하여 석탄의 원소분석 조성, 발열량, 회분함량, 회분조성, 회 용융점 등의 변수에 따라서 각각 해당 가스화기에서 가스화되었을 때의 생성되는 합성가스의 조건을 시뮬레이션을 통하여 얻었다. 가스화기 시뮬레이션 결과를 토대로 합성석유 및 합성천연가스 생산을 위한 공정의 물질수지식 및 에너지수지식이 계산되었으며 이로부터 각 공정에서 발생되는 부생성물과 폐기물에 대한 양이 결정되고 이를 처리하는 방안 등도 제시되었다. 실증시설은 20,000배럴/일 규모의 CTL 및 전기 병산 시설이 적합하다. 더 큰 규모 공장은 투자비가 너무 커서 유가 또는 석탄가 변동에 따라 사업의 수익성이 크게 변하여 위험도가 큰 단점이 있기 때문이다. CTL 공장에 전기 병산이 추천되는 이유는 산소생산공장(APU), 압축 등 석탄전환공장에는 자체적인 전기수요가 막대하여 따로 스팀터빈용 발전소를 운영하므로 이를 효율적으로 대체하고자 하기 때문이다. 즉, 석탄가스화에 의해 기름을 최대한 만들고 미반응가스는 가스터빈 및 스팀터빈의 복합발전에 의해 고효율로 전기를 생산하면 최소의 비용으로 최대한 전기를 생산하여 자체소비 전력을 충당하고 남는 전기는 판매하여 수익률을 높일 수 있다.

We can say that there are several majors in the course of cartoon education of college; cartoon, manpyung, 4 panel comic strips, editorial cartoon, webtoon and so on. Among them, this study starts with concrete question; "How can we encourage students to understand 4 panel comic strips better in the educational course of 4 panel comic strips?" 4 panel comic strips divided into two groups, depending on the materials. The first is daily cartoon which depicts the emotion in daily life. The second is editorial cartoon which deals with the problems of society in the ironical and witty way. Judging from my own thoughts that it would be better in the understanding and analysis of structures to take editorial cartoon in which materials are confined to social problems, this study treats rhetoric expression and structures of 4 panel comic strips. Introduction, development, turn and conclusion of "Jangdori" on Kyunghyangsinmoon are good materials for this study. So, "Jangdori" is in the center of this study. The objective of this study is to provide knowledge in creating 4 panel comic strips with the understanding the area of 4 panel comic strips through the analysis of the rhetoric expression and structures of this field. Even though this study has a limit, no access to daily 4 panel comic strips, I hope that this study would be a little help in any places in which the education of 4 panel comic strips is needed as a part of a course of cartoon in college.

The concerns for higher returns among investors in Korea are increasing as local interest rates lag behind the global market. The aim of this study was to provide a basis for estimating the precise return on investment to private investors and stakeholders of office buildings by identifying the optimal scale estimation of office building space, derived from managerial expenses. The literature on the economies theories of scales were reviewed, and the average administrative costs on an appropriate scale were assessed by cross-analysis and regression analysis using the U-shaped quadratic and cubic function. The findings suggest that the average office building managerial costs are approximately 6-11% according to the region, 10-13% according to the grade, and 8-9% according to size. Corporate-owned buildings represent the highest in terms of the average managerial costs, and there is an approximately 11.5% difference when it comes to outsourcing. In addition, the elapsed year showed that approximately 5.3 years to meet the lowest U-shaped curve of the average managerial cost. The 'Total floor area' variable shows a ${\bigcap}$-shape as it continue to increase to 72,000-Pyung then decrease gradually. This study presents the fundamental proposition of efficient and practical management of cost, lease and operation for real estate management firms by utilizing LCC.

The advent of Social Journalism coincided with the rise of social media to create and deliver news information; as a type of civic journalism, social journalism may be characterized as a new form of information gathering and news reporting which is fed by citizens creating news information through their use social networking services (SNSs). The current study analyzed a Facebook page called, to determine how this page was utilized during the onset of the citizen movement for the Egyptian democratic revolution to produce news, to facilitate interaction among the public and to deliver the news under the form of networked journalism. Each post uploaded onto the Facebook page from January 27 till February 2, 2011 was coded in its category, content and the contextual frame of the news. The results of the study showed that during the first week, straight news rather than those with opinions was produced most frequently. The research findings of the current study suggest that in a society of political turmoil, such as in Egypt and other Arabic countries, when the institutionalized media are controlled severely by the government or other forces, SNSs can perform journalistic media roles which create and distribute news information representing facts and reality, and simultaneously facilitate the public's interactions on social and political issues.

This study concerns especially Choryang-Weagwan which was the largest Japanese House left in Pusan through Chosun Dynasty.Choryang-Waegwan was known to have been jointly constructed by Korean and Japanese carpenters. Therefore, Weagwan was a place for exchange of architectural tradition (special features such as sliding door and straw mat) between Korean and Japan. Judging from this point of view, It is certain that mutual influences helped to shape architecture of Choryang-Weagwan. After establishment Choryang-Weagwan was gradually extended, owing to the prosperity of trade with Japan. But since late 18th century government of Chosun did not give as much care to maintaining Choryang-Weagwan as a result of deteriorating condition of commercial and diplomatic relations with Japan. From the beginning of Choryang-Weagwan construction, Superintendents of the construction were called Hun-do and Byl-cha, who acted as official interpreters as well. And, during construction works, they were called Gamdong-gwan. At the start of construction, Weagwan was built partly in Japanese-style by the carpenters from Tokugawa Shogunate. But as time passed, the participation rate of Japanese carpenters diminished gradually. After 1831, Japanese technician vanished extremely and repairing construction was continued by the Korean

In this study, Community Garden of various national and international practices trends to an advanced research, the concept of community garden participated with a group operation out of initiative to produce safety food while securing space for the community, ensuring the area that has gone through a new form of active secure urban green space plan, urban renewal movement was defined as the mean. Furthermore, for the purpose of improving the poor welfare environment by attempting to experimentally make a community garden of a disabled welfare house rooftop and how to target its planning and construction process, partnership involvement, business processes have been investigated, such as cost sharing. The whole process including a budget for development of this case was conducted by the Busan Green Trust. Standard Chartered (SC) First Bank's 50% fund share by community chest, participation of volunteers, support of Busan City and Saba-gu, outside of that, sharing parts or trial to participate by diverse partnership of enterprise, public corporation and laboratory, these are the key in developing community garden's model. Established community garden places resulted food production to users of welfare center for the disabled, participating urban agricultural experience program, horticultural therapy, complex community chapter and cultural center. Furthermore, we could find the meaning of rooftop community garden in the point that it is a low cost garden by applying movable and unmovable planters. This study is profitable for improving urban environment, ensuring community chapter and urban green areas, regenerating a city to develop experimental community garden model by using a welfare house rooftop.
