This study was conducted to determine the location determinants that influence the sales of the "Storyway" convenience stores built at the country's railway stations. The preceding studies were about the convenience stores located in the residence-business areas or along the roadsides. This study, on the other hand, focused on the characteristics of the stations, based on a theory that is different from the existing theories. The targets of this study were the 301 "Storyway" convenience stores doing business in the 198 railway stations in the country, and the dummy parameter and hedonic-price model function were used for multiple regression analysis. For the study results, it was found that the number of people using the railway and the size of the store have a positive effect on the sales whereas the other brand competitors have a negative effect thereon. Second, the subway stations holding 89% of the total passengers in the country have unexpectedly no positive influence on the sales. Third, depending on the transfer, it was found that no transfer station had smaller sales than the transfer stations. Finally, as for the location of the stores in the station, the stores located on the platforms or passageways have a smaller turnover rate than the stores in the welcoming spaces and squares. This research result shows that when starting a convenience store business, the number of people using the railway, the size of the store, the transfer possibility, and the location of the store inside the station have to be considered under the circumstance of recession on the part of the convenience stores due to excessive competition.

This study is aimed to reflect the current status survey, analysis and response of 10 railway stations using geographical names in one of 19 stations located on Gyeongbu, Honam and Chungbuk line. Most railway stations in the study have shown normal images that are close to the standard type by selecting similar building materials rather than reflecting geographical features. Aside from the shape of the traditional Korean house in Cheongju, almost all newly constructed stations tend to incorporate light gray plating material on their modern exterior to produce Family look design as a railroad station. According to a survey of the sensitivity of the station's name, Osong Station was 73.6 percent, Gyeryong Station 67.3 percent, Heukseok-ri Station was 64.5 percent, Shintan-jin 62.6 percent, and Yeonsan Station 57 percent, more than half. Therefore, the results of the five stations were presented as a calculation and proposed design release focusing on the facades of each station. Each of these stations suggested a way to express the facade design image, considering the railway operation status of Korea Railroad, the area of the station and other surroundings.

The 1st Incheon Rapid Transit Line opened in October, 1999. However, the current development plans for areas near stations do not involve plans for the both urban planning and transportation together. As the focus on only the aspect of installing a new transportation mode, the developments even make the problems such as reckless development and traffic congestion gets worse. It is required to analyse status of the current land uses and land use plans in the future and consider distribution of functions of the areas near stations and aims of development plans so as to harmonize the functions of each region in view of making balance in the whole city. The aims of developments of areas near stations has to focus on the study follows steps to find and suggest aims and strategies for the revitalization plan for areas near stations with considering the both transportation and land uses together. The plans for the areas near stations of the Incheon 1st Rapid Transit Line are analysed and then the features and rational strategies are derived. The impact is analysed as applying the development strategies derived from the step into the areas near the stations of Incheon 1st Rapid Transit line.

Although air, water, and noise pollutions have been widely recognized, electromagnetic forces (EMF) hazard has been rarely recognized as a pollution and very little studies has been done in this country. Thus, in this study electromagnetic forces radiated by various home appliances, office machines, and communication equipments were measured and so were several places radiating strong EMF such as subway stations and electric substations. Among the home appliances microwave oven radiates lots of magnetic field and microwaves, and electric mattress does strong magnetic field. In video game room strong magnetic and considerable electric fields were measured. It was observed strong magnetic field inside of electric powered train and very strong magnetic and electric fields on some platforms. Hand-phone and car-phone radiate very hazardous level of microwaves to brain and that they rapidly come into wide use. In this study data base for various electric machines and places radiating strong EMFs were constructed and could be used for future epidemiological studies.

Since 2010 December, the Gyeongchun line can provide better service than the other modes in respect of cost & time efficiency by operating electric double track from Sangbong station to Chuncheon station. However customers living in the Northern part of capital area, which there are stations of line No.1, have inconvenience to transfering twice to access Gyeongchun line. To minimize inconvenience, this study has analyzed the demand variation of Geongchun line upon changing the terminal of some trains on Gyeongchun line which reduces the number of transfer. In this study, the demand variation has been estimated by the direct demand model considering only saving time between O/D. So some additional modifications are required, because the effect of fare and accession convenience has not been considered.

The use of autogenous tissues is preferred for knee ligament reconstruction. However allografts play a role in major ligament reconstructive procedures in which multiple substitutions or revisions are required. In the dislocated knee, allografts may offer an advantage in reconstructing the PCL. But allografts in knee ligament surgery must be considered in terms of biomechanical and regenerative properties, disease transmission and immunogenecity, and methods of preservation and sterilization. Also only a few authors have described the use of allograft for reconstruction of a ruptured PCL, either a single procedure, or in combination with ACL repair following knee dislocation. Furthermore, the problems that the clinician faces with use of allografts is the necessity for supervision to ensure that the grafts are correctly processed, secondarily sterilized, and free of transmissible diseases. For these reasons, the routine use of allograft materials in the treatment of ligament deficiencies should be avoid and provide with meaningful outcome studies, including longterm follow-up.
