This study reviewed details and case studies of district unit planning to preserve and develop urban tissues concerning a historic urban environment and provide implications for future practice. In particular, this case study examined the role of the district unit planning in city conservation rooted in the experience of Incheon's old town. The old town begins with the opening of Incheon Port and concessions, including Japanese, Qing Dynasty, and multinational settlements. Second, the study established land subdivision planning and reviewed the institutions to encourage urban tissue. Third, the conservation guidelines influenced the conservation and utilization of the streets, such as alleys and old coastlines, the form of parcels called deep and narrow lots, and the exterior elements of buildings. This study also derived implications for the future. First, the street with historical value in the settlement should be excavated further. Second, the parcels in the settlement limit redevelopment to maintain the unique morphological characteristics. Third, the exterior of the buildings should be provided with planning incentives to induce conservation and utilization.

This study concern with the pattern of Pusan Station Shopping District within Pusan City, Korea, one of the third ranked centers within Pusan-the first ranked is CBD, the second is subCBD, the third are Spa Shopping district, Tongnae shopping district, Jobang-Ap shopping district and Yangjeong shopping district. This paper serves as a part of series studies which attempt to clarify the internal structure of Pusan as a whole. Part(I) of this study deals with the pattern of functions including information & culture, business, recreation and retailing. The results are as follows. 1. Pusan Station is one of higher ranked class of central places within Pusan City. But the ratio of dwelling houses is the highest in Pusan Station among the 9 higher ranked central places within Pusan. It means that the residential areas still remain along the maze type of narrower streets inner part of the blocks, especially western belt of this shopping district. 2. Business functions are one of the important criteria which classified the central places within the city and Pusan Station is the first ranked shopping districts in terms of these criteria among the 9 higher ranked central places including CBD within Pusan City. It suggests that Pusan Station is the miniature of the CBD, SubCBD is not the miniature of CBD in the view point of business function. It also means that Pusan Station Shopping District has been developed as a special shopping district or as a special central place. It has not been evolved as a center of the hierarchy of central places within the city by the natural or organic growth. 3. Pusan Station as 'the third space or drinking place' and it's characteristics as a amusement center presents at so called the 'Texas Town'-free tax area- whose customers are mainly U. S. soldiers and foreign sailors. But from the 1990s, this 'Town' changed to 'Russian Town', You can easy to meet many Russians and Russian lettered signboards-not English- along the street. 4. Convenient stores distribute mainly at back streets or along the narrower streets. It means that this kinds of stores have a residential oriented character. And a certain convenient stores locate with almost same distances. It suggests that it's hinterland is limited in nearer neighborhoods.

The purpose of this paper is to investigate the value chain efficiency of Korean port investment by using the newly developed multi-year and multi-stage value chain efficiency model of DEA(Data Envelopment Analysis). Inputs[port investment amount, cargo handling capacity, and berthing capacity], and outputs[cargo handling amount, number of ship calls, revenue, and score of customer service satisfaction] are used during 14 years(1994-2007) for 20 Korean seaports by using two kinds of DEA models. Empirical main results are as follows: First, Model 1 shows that the ranking order of multi-stage value chain efficiency is Stage 2, Stage 3-1, Stage 1, and Stage 3-2. And according to the value chain average efficiency scores, ranking order is stages 2, 1, 3-1, and 3-2. In Model 2, 3(Incheon, Mogpo, and Jeju) out of 9 ports show the ranking order of Stages 2, 3-2, 3-1, and 1. And value chain average efficiency scores rank in order of Stages 2, 3-2, 3-1, and 1. Second, the difference among the value chain efficiency scores of each stage comes from the efficiency deterioration of all ports except Stages 2 and 1 in Model 1. In Model 2, value chain efficiency scores among the Stages 3-1, 3-2 compared to Stage 1 were deteriorated. The main policy implication based on the findings of this study is that the manager of port investment and management of Ministry of Land, Transport and Maritime Affairs in Korea should introduce the multi-year, multi-stage value chain efficiency method for deciding the port investment amount and evaluating the effect of port investment after considering the empirical results of this paper carefully.

Shipping and ports have important roles as the nodes and links in maritime logistics. The environment between shipping and ports is interrelated and has been changing' together. Recently, the changes of shipping and ports are rapidly in progress and it is expected to be developed complementarily. Especially, mega carriers reduce the number of ports of calls because the size of ships is becoming bigger and bigger and the 'hub and spokes' strategy is appeared. Therefore, the position of a hub port by the region has questioned This paper aims to research the competitive ports by the region on the basis of the patterns when mega carriers call at ports. Six regions, Far East, Southeast Asia, Northwest America, Northeast America, West Europe and Mediterranean, are organized for this research. According to the volume of cargoes, the top five ports of each region are analyzed. As a result, the competitive ports by the region are Shanghai, Hong Kong, Los Angeles, New York New Jersey, Rotterdam and Gioia Tauro.

The years from 1895 to 1915 marked an important period in Korean because it was the start of modern education during which a new school system was developed. In particular, the Government made laws and rules concerning the use of textbooks in schools. In this research information about books in use in schools was obtained from the {School Textbook List} which was drawn up during this period. Science textbooks printed in Korea from 1895 to 1915 were control1ed in their use by the Ministry of Education and the Government General of Chosen. They used the Private School Ordinance, Regulations for Official Examination of Textbooks in 1908, and Law of Publication in 1909 as the main means of controlling textbooks. The official examination of textbooks under the Japanese rule of Korea resulted in an increasing number of science textbooks being banned. While science textbooks had enjoyed more freedom from control by the Government General of Chosen than other textbooks, the situation changed significantly as Japan to intensify the control of all kinds of textbooks in Korea.

This study targets ten titles of Hangul banggakbon novels in the Harvard Yenching Library to examine the bibliography, system, and characteristics. Among the ten titles, gyeongpanbon Guunmong, Leehaeryongjeon, Chunhyangjeon, Janggyeongjeon, two titles of Sodaeseongjeon, Honggildongjeon, anseongpanbon Yangpungunjeon, and two titles of wanpanbon Hwaryongdo have been found in Korea, too. However, gyeongpanbon Chunhyangjeon, 30 jangbon of Hyogyosingan(孝橋新刊), and wanpanbon Hwaryongdo seogyeseopobon are the ones that can be hardly found in Korea, and the library has possessed it there so far. With the two titles of Hangul banggakbon novels, it will be needed to reexamine the aspects of publishing Hangul banggakbon novels afterwards. Hangul banggakbon novels that Harvard-Yenching Library has now are mostly the ones that can be easily found in Korea, too. It is because the data started to be collected from the 1950's. In comparison with the materials in England, Russia, or Japan in the early 1890's, there are no rare books that cannot be found in Korea. The reason for this may be found from this.
