This study is aimed at considering the relationship between the influential factor in Smartphone purchase and consumer awareness. For this purpose, this study set up the influential factors in Smartphone purchase as advertising effect, brand effect and usability effect and corporate image effect, and considered the relationship between these influential factors and consumer awareness empirically. The research results can be summarized as following 3 parts: First, the four factors suggested as the influential factor in Smartphone purchase were verified to have a significant influence on customer satisfaction and customer loyalty, and thus, it is thought that the bigger the influence of these factors, the more customer satisfaction and customer loyalty will increase. Second, among the factors suggested as influential factors in Smartphone purchase, the biggest factor in influencing customer satisfaction was found to be 'Usability Effect' while the biggest factor in influencing customer loyalty was revealed to be 'Brand Effect.' As a result, this study could learn that it's necessary that 'Usability Effect' should be considered more preferentially than other factors in order to enhance customer satisfaction while 'Brand Effect' should be preferentially considered in orderto raise customer loyalty. Third, it can be judged that in the relationship between customer satisfaction and customer loyalty, the bigger the customer satisfaction, the higher the customer loyalty. It is hoped that such research results could be applied as useful materials in time of establishing the marketing strategy. Nevertheless, this paper makes it clear that due to the constraints in the number of sample areas and samples, there is a limit in objectifying the research results into all areas.

This study is to identify the factors affecting commuting time and modes in urban and rural areas using household traffic survey data. The findings indicated that commuting time using passenger car in rural areas was 1.6 times longer than those in urban areas. When citizen use public transportation, however, there was not much difference in commuting time in urban and rural areas. Among the various factors affecting commuting time in rural areas (13 factors have statistical significance), the most influential factors were that public transportation, managers and office workers, functional and device managers, and passenger car. In urban areas, the highly influential factors were public transportation and walking among the 16 affecting factors which have statistical significance. The commuting time in rural areas increased according to the occupation types, but the commuting time of full-time workers decreased. This phenomenom means that occupation groups with the full-time system prefer residential areas in the densely populated town.

The purpose of this study is to segment the social awareness on the function of public benefit of agriculture and rural areas by socio-economic and action/attitude characteristics, and to identify the influential variables in social awareness. The nationwide survey of 1,200 adults aged over 20 was conducted, and the data was analyzed by PASW statistics 17.0. One of the awareness variables was the degree of the consent to the preservation of the public beneficial function. This variable was segmented by the interest on related information, the criteria of buying agricultural products, occupation and age. And the other awareness variable was the willingness to pay for the preservation of the public beneficial function. This variable was segmented by the education, occupation, income and the experience of living in rural areas. According to the results, some suggestions for improving the social awareness on the public beneficial function of agriculture and rural areas were discussed.

도시화가 진행되는 소유역(성내-고덕천 유역)에 대하여 지하수 질산성질소의 공간적 분포에 미치는 영향요인을 규명하고 각 요인들의 오염기여도에 대한 상대적인 차이를 파악하기 위하여 GIS를 활용한 공간분석을 실시하였다. 영향요인으로는 토지이용도, 하수관 거리, 포장율, 녹지율 등을 고려하였다. 공간분석 결과, 토지이용도 중에서 도시화 지역과 경작지 등에서는 서로 상이한 질산성질소 분포가 나타났으며, 이는 도시화 지역에서는 하수관으로, 경작지에서는 비료성분으로 인하여 질산성질소 분포의 차이가 나타날 수 있음을 지시한다. 지하수 관정에서 하수관까지의 거리가 $60\~75m$ 정도 지점까지는 거리의 증가에 따라 질산성질소 농도가 감소한다. 특히 도시화 지역 내에서 하수관거리와 질산성질소 농도가 음의 상관도를 보이며, 이는 하수관이 질산성질소의 주 오염원임을 의미한다. 또한, 도시화 지역 질산성질소 농도와 포장율이 음의 상관도를 보이는 것도 질산성질소의 오염물질이 지표면에 기인하고 있음을 지시한다. 결과적으로 도시화가 급속히 진행되고 있는 지역에서는 하수관의 설치와 유지관리 및 토지이용형태에 대한 체계적인 관리가 지하수의 질산성질소 오염예방에 중요함을 의미한다.

Changes in household composition and the residential environment have had a considerable impact on the features of postal delivery regions in recent years, resulting in a large increase in the overall workload of domestic postal delivery services. In this paper, we provide complex analysis results for postal delivery areas using various unsupervised learning approaches. First, we extract highly influential features using several feature-engineering methods. Then, using quantitative and qualitative cluster analyses, we find the distinctive traits and semantics of postal delivery zones. Unsupervised learning approaches are useful for successfully grouping postal service zones, according to our findings. Furthermore, by comparing a postal delivery region to other areas in the same group, workload balancing was achieved.

The purpose of this study was to analyse the relations among the residents' characteristics, the policy of the facility, and the physical characteristics of activity areas, and to understand the elements for the lively use of activity areas in the elderly nursing facilities. The results of the study are as follows: First, there was a relationship between the characteristics of semi-public activity areas and the residents' management-control policy. The facilities having semi-public areas of living room type showed more flexibility in time and place and more respects for the residents. Second, the activity areas of connection type were much more used than the compartment type, especially in the facilities having more residents incapable of walking. On the other hand, the facilities having high control for the residents showed high using rate in public activity areas, and all those did not have semi-public areas or showed low using rate in there. Third, in the analysis of the relationship between the physical characteristics and the using rate of activity areas, the public activity areas having compartment type in the spatial composition and hall as a form were likely to have multiple usages. On the whole, the various form of activity areas, the area per residents, openness, accessibility and centrality were having interactions each other for high using rate in activity areas. Especially, many stimulations and the furniture arrangements that were good for the residents' interactions had a function of compensation for the poor physical characteristics of activity areas. This study investigated only the using rates to understand the lively use of the space. For the future study, it is suggested that the detail using behavior of the residents should be examined to understand the influential elements.
