Among the various application to use FRID, the parking control system widely uses it recently. However, it is rare for the existing systems to integrate several parking lot in the clustered shopping center. This paper proposes the integrated parking control system based on RFID. The system searches optimal path to parking lot with due regard to the position of users who own a tag and the status of parking lots. Then, it transmits the path to mobile devices of the users. The system consists of main server, middle ware to filter and manage tag information, parking lot client to send and manage the status of each parking lot and application module of mobile devices based on WIPI for displaying the optimal path. The main server integrates these components by a database and a new method to filters and manage tag information is newly proposed for the sake of maintaining the position and the direction of the cars in the middle ware. The implemented system shows that it is highly expected to be useful in an advanced integrated parking control system.

3D data are in great demand for pedestrian navigation recently. For pedestrian navigation, we needs to reconstruct 3D model in detail from people's eye. In order to present spatial features in detail for pedestrian navigation, it is indispensable to develop 3D model not only in outdoor environment but also in indoor environment such as underground shopping complex. However, it is very difficult to acquire 3D data efficiently by mobile mapping without GPS. In this research, 3D shape was acquired by Laser scanner, and texture by CCD(Charge Coupled Device) sensor. Continuous changes position and attitude of sensors were measured by IMU(Inertial Measurement Unit). Moreover, IMU was corrected by relative orientation of CCD images without GPS(Global Positioning System). In conclusion, Reliable, quick, and handy method for acquiring 3D data for indoor environment is proposed by a combination of a digital camera and a laser scanner with IMU.

The Gongju Sanseong Traditional Market, the subject of this study, was formed in the early 1900's, and along with the development of Gongju, it has been constantly changed and expanded up until now. The Sanseong Traditional Market located in Gongju, the Korea's representative historic city, exhibits merits in the aspects as a city based on the symbolic significance of the city where it is located and historical characteristics; however, it also presents some problems as well in consideration of user convenience and accessibility. Thereupon, this study conducted literature review on traditional markets, field research with a field trip, and a survey in order to analyze the spatial characteristics of the market environment and grope for the methods of activation. The conclusion suggested through this is as written below: First, the changes of types regarding spatial use according to the modernization project of traditional markets are essential, so about the spatial use according to the spatial changes, it is needed to distribute it balancedly considering the central space of the market. Second, with the understanding of the spatial types of traditional markets, it is needed to build a plan for alternation in the types of physical space based on that. Third, it is necessary to suggest the methods of integrated spatial use among standing markets and 5-day markets. In particular, through the approaches from the aspects of architectural and urban design and through reasonable spatial planning, a systematic approach considering the convenience of the users and merchants using it as their living space should be prioritized. And lastly, it is needed to reorganize the space according to the physical and non-physical methods in order to figure out the methods of activating traditional markets in agricultural areas and minor cities. With the complex approaches above, we can grope for the methods of activating traditional markets.

Purpose - The purpose of the research is to identify the demographic characteristics of the customers with high private label purchase intention. According to the previous research demographics such as gender, age, income, and residence type affect private label purchase intention indirectly through psychographics rather than directly. For instance, higher income group is time pressured, price-insensitive, quality-sensitive, less likely to enjoy shopping utilitarian products, and less likely to be variety-seeking. The main contribution of this research is to verify the results found in the previous empirical foreign research using scanner data and to investigate the differences of the characteristics of private label users between Korea and the foreign countries. Research design, data, and methodology - In order to empirically test the proposed hypotheses, scanner data of a Korean major super center was analyzed. Results - Empirical results show that private labels are more favored by old people over 50s, dwellers in individual house, lower income group, and frequent store visitors. Age of 30s, dwellers in the apartment of 30 pyung, higher income group, and consumers who purchased a large amount are less likely to purchase private labels. Gender turned out not to affect private label purchase. It should be noted that there is a significant multicollinearity among independent variables. Conclusions - The research findings provide managerial implication for retailers' private label strategy. In general, retailers heavily send private label coupons to the customers with high purchase volume. According to the research, however, store visit frequency is much more positively associated with private label purchase than purchase amount. The study has some limitations. The samples are only consumers with private label purchase experience. The data were drawn from one store and only 8 commodity products were used for the analysis. Also, if more demographics were available, a more complete description on the private brand users' profile could have been derived. We propose the following future research. Research using the data including consumers without private label experience, research investigating direction of causality between private label loyalty and store loyalty, and research using hedonic private label products such as TV and PC could be promising.

This study compared the recommended levels of illumination for housing. KS Recommended Levels of Illumination (KS A 3011) in Korea, Recommended Levels of Illumination (GB 50034-2004) in China and Recommended Levels of Illumination (JIS Z 9110) in Japan are compared. The results are as below. First, recommended levels of illumination used in Korea China Japan are suggested by different locations and activities. However, classification for application scope is set differently. There are 10 areas for classification used in Korea, 5 areas in China, and 13 areas in China. When medium levels for classification are included as classification level, total of 15 areas are used for classification in China. Second, when considering there are 15 areas of application scope in China for recommended levels of illumination, there are 7 areas that are commonly used in Korea China Japan. 7 areas include stadium, factories, hospitals, office, shopping center, houses and hospitals. Third, working surface is considered as the height for recommended levels of illumination in Korea China Japan. Korea and Japan consider all working positions, standing and sitting position, when deciding the height. However, China only considers the standing position. Fourth, application scope for recommended levels of illumination for housing are classified in 16 areas in Korea, 5 in China and 18 in Japan. Thus, the application scope for recommended levels of illumination in housing in Korea is similar to Japan. However, there are only 5 areas used in China such as living room, bedroom, dining room, kitchen and sanitary room. Fifth, recommended levels of illumination is classified in 3 levels such as Lowest-Moderate-Highest while China and Japan only have standard recommended levels of illumination. Sixth, when observing recommended levels of illumination by type of activities, Japan classified the activities in greatest detail followed by Korea and then China. Seventh, Recommended levels of illumination differs by each country.

The modified repeat-sales model is employed in this study in order to identify differentiating impacts of time-varying accessibility characteristics on housing price. The results demonstrate that accessibility measures have very differential impacts on housing price over time. The improvement of accessibility through newly built facilities and apartment complex has either increased or decreased housing price. For example, the new subway line 9 has positive impact on housing price nearby, therefore price gap between subway access area and the other parts has been increased. The impact of the wide area facilities such as shopping center and hospital are decreased because they can be used more easily by the new subway line before. However, the small service area facility such as elementary school doesn't lose their impact even though subway accessibility extremely increased. The results imply that new facilities in existing residential site can affect not only housing price but also the other facilities' impact of housing price.

Korean logistics industry have been focused on transportation business. However, with the expansion of the electronic commerce and on-line shopping, delivery service is now dramatically growing. Despite the expansion of logistics market, the domestic logistics industry have significant structural problems such as low productivity comparing with the advanced countries, relatively high cost and shortage of human resources and lack of professionalism of people in the industry. Logistics companies reallocate employees, use subcontractors, expand consignment and training the employees to overcome the labor shortages but it has some limits. In recognition of the importance of labor in the logistics industry, financial support and investment have increased. Logistics companies tend to hire consultants, set up logistics department or R&D center in order to establish highly productive logistics process and system so it is viewed that there will be considerable demands of human resources in the logistics industry. This study indicates implications and development direction of human resources in the logistics industry by looking into prospect and characteristic of the industry, employment status, training programs and qualification requirements.

The aim of this thesis is to present why the business district of old downtown in Jejusi collapsed and what sort of problems caused by that as collecting objective data, which help us to comprehend how the commercial zone has been decaying, on the physical state of the specific area near 'Sinheungro' and 'Chilsungro', which are main commercial sites in the downtown, and analysing it. Firstly It was revealed that most land investigated was property in which structure was able to built or poor land within $60m^2$. This was caused by increasing in land value and high density in space use so that the area did not develop. Secondly, In addition to be low density, most of buildings in 'Sinheungro' and 'Chilsungro' were so old and inefficient - the old buildings were abandoned without improving due to expensive rent and complicated property rights. Thirdly, According to the survey accomplished, major commercial facilities in the area have struggled with the continuous recession in their business. It was the inevitable result of not having an effective alliance with surrounding retail shops and a lack of a strategic action for satisfying consumers desire or adapting to new shopping patterns. Fourthly, Infrastructure in the site was ruining the beauty of the urban landscape as well as bringing on bad access to the inner city as not having improved enough. Furthermore, many administration departments which were in charge of each infrastructure existed. This was resulted from not considering unification between each infrastructure and regional characteristics of the local community.
