Purpose: Geographical relocation has been conducted to alleviate overcrowding and to support balanced regional development in many countries. Previous studies have seldom examined the effectiveness of relocation on job and life dissatisfaction, particularly in the public sector. The purpose of this study is to investigate the determinants of relocation on job and life dissatisfaction. Proposed research questions include the following: i) do working conditions in the new workplace and interactivity affect job dissatisfaction? ii) do social infrastructure and social activity in the new location affect life dissatisfaction? and iii) is there a relationship between job and life dissatisfaction? Research Design, data, and methodology: The study collected data via an online survey and applied statistical analyses such as factor analysis, regression, and ANOVA. Results: The results of this study found that proposed determinants excluding mobility inefficiency and decision-making affect job and life dissatisfaction. The results also showed that there are relationships between job and life dissatisfaction. Conclusions: The results of this study provide both managerial and policy implications of relocation for the public sector. The results of this study implied that better policy should be designed to increase job and life satisfaction that also accounts for the realities of relocation.

E-commerce in Korea has grown steadily in recent years. E-commerce has provided firms with an effective method to approach potential customers by overcoming geographical and physical barriers. However, despite the rapid growth, many e-commerce businesses closed their businesses and were not able to survive. This study aims to empirically examine the factors that determine the survival of e-commerce businesses in Korea. In particular, this study focuses on the factors related to the notion of institution-based trust that includes delivery, privacy, and security management. This research used the data set about 31,295 e-commerce businesses that have been registered in Seoul. We found that the e-commerce business that does not require extra personal information beyond the standard terms and conditions or provides a feedback mechanism by having an online board to submit a complaint has a higher chance of survival. In addition, the e-commerce business that has a secured web server, shows the specific information about the date of delivery, or provides escrow services is likely to survive longer than others. The research has extended the extant literature on the importance of trust in e-commerce by empirically examining the effects of the institution-based trust factors on the actual survival of e-commerce businesses.

Plans to utilize the resources of the coast guard are underway for the revitalization of the area and the development of tourism resources in recent years. As most of the plans have been focused on some specific factors such as geographical or regional conditions, and therefore systematic approaches are needed in corporation with other related projects. This study suggested the measures on activating the coastal tourism resources for Woodoo~Woocheon village in Goheung-gun by using the coastal landscape elements. The current status of natural environment and tourism resources for coastal regions were investigated in Woodoo~Woocheon village and plans for enhancing connectivity with local residents were suggested. Based on the scenic values of coastal region, landscape were assessed from the perspective of the sustainable coastal tourism resources in the future. Several solutions were suggested to enhance tour values; coastal deck road to enhance connectivity between resources and accessibility of foreign tourists, social communication among local residents and authorities, continuous development of cultural and historic resources in local area. In addition, information signs and new stair ways would be needed to improve the accessibility of tourists. In the future, if the plan for this study was to generate profitability with persistence, it suggested that there was a way to move forward in conjunction with the profit rate local projects distributed around it.

As the modern societies have become complicated and diverse, people's interest in "leisure time" has been higher than ever before, especially in relation to 5 day work a week. The increasing weekend trip and the travlers' demand for the better service and the convenient accomodations gave birth to "Pension" as one of accomodations in Korea. This study focuses on the attempt to plan and design the establishment of the competitive "Pension" which are popular between travelers in their twenties and thirties living in cities. This study also attempts to find the solution of the problems in relation to the actual conditions of the pensions which are built and under construction, and to suggest a new revised concept of pension. The summary is as follows: 1. This study focuses on the special theme of building Mo-Hyun Myon pension community with originality and new style of management. 2. This study includes the introduction of the special agency which makes reservations, promotes, and manages for the convenience of customers and buyers. 3. It pianos to secure the public area for various events and rests. 4. The geographical features of the site where the complex stands will be fully utilized to maximize the beauties of nature.

In small-scale water systems, the measurement of quality of raw water in running water is generally implemented when the quality of water is stable and frequency of measurement is low. However, units such as water temperature and pH, which are easily monitored, are frequently measured. In establishing an improvement plan for a water treatment system, the range of concentration of the target material present in the raw water of the running water provides relevant information. If the concentration of target material can be specified by the quality of water of data items that are measured daily, inverse estimation of the range of concentration is possible as well. In this paper, we took note of manganese in the raw water from Ogasawara-mura, Tokyo, and estimated the manganese concentration in the raw water of the running water for the past five years. Based on the results obtained, we have proposed a manganese removal system, considering the current situation and geographical conditions of Ogasawara-mura.

During the summer season, more than half of the annual precipitation in Korea occurs during the summer season due to the geographical location in the Asian monsoon belt. So, this causes severe soil erosion from croplands, which is directly linked to the deterioration of crop/land productivity and surface water quality. Therefore, much attention has been given to develop accurate estimation tools of soil erosion. The aim of this study is to assess the performance of using the empirical Universal Soil Loss Equation (USLE) and the physical-based model of the Water Erosion Prediction Project (WEPP) to quantify eroded amount of soil from agricultural fields. Input data files, including climate, soil, slope, and cropping management, were modified to fit into Korean conditions. Chuncheon (forest) and Jeonju (level-plain) were selected as two Korean cities with different topographic characteristics for model analysis. The results of this current study indicated that better soil erosion prediction can be achieved using the WEPP model since it has better power to illustrate a higher degree of spatial variability than USLE in topography, precipitation, soils, and crop management practices. These present findings are expected to contribute to the development of the environmental assessment program as well as the conservation of the agricultural environment in Korea.

This study analyze the change of wind pattern and intensity according to the transform of surface conditions, such as land use and height of terrain, over the leeward region. In order to do this, we have employed 'Envi-met' microscale atmospheric numerical model. When the same wind condition is considered, the wind speed of base case having natural surface condition of Chunsudae shows the weakest strength among different cases such as the 'bare case' and the '20 m case' which the plants is removed and the height of terrain is flatted as 20 m above the sea level over the Chunsudae, respectively. The weakening of wind speed is a maximum of $4{\sim}8 m/s$ when the inflow wind speed is 55 m/s.

In a vehicular ad hoc network, the communication links are unsteady due to the rapidly changing topology, high mobility and traffic density in the urban environment. Most of the existing geographical routing protocols rely on the continuous transmission of beacon messages to update the neighbors' presence, leading to network congestion. Source-based approaches have been proven to be inefficient in the inherently unstable network. To this end, we propose an opportunistic beaconless packet forwarding approach based on a modified handshake mechanism for the urban vehicular environment. The protocol acts differently between intersections and at the intersection to find the next forwarder node toward the destination. The modified handshake mechanism contains link quality, forward progress and directional greedy metrics to determine the best relay node in the network. After designing the protocol, we compared its performance with existing routing protocols. The simulation results show the superior performance of the proposed protocol in terms of packet delay and data delivery ratio in realistic wireless channel conditions.
