PURPOSES : Most of the traffic surveys are carried out by an inspection method by the manpower. In some cases, the video equipment is used only in some regions when the traffic volume is surveyed. In this case, there is environmental restriction that the road equipment to fix the video equipment should exist. Also, in areas where information such as digital maps and satellite photographs is old or not provided, they are forced to rely on manpower research, but it is difficult to put huge amounts of time and money into the research in places where labor supply and demand is difficult. This difficulty is particularly pronounced in overseas business. METHODS : The purpose of this study is to improve the efficiency of business by using the drones in the traffic investigation through analysis of the cost reduction effect between the existing method and the proposed method in the overseas business traffic survey. The scope of the research is limited to the scope of research, and based on the case of overseas projects, the method of using drone for each research sector is suggested. RESULTS : In the traffic condition survey section, we propose the use of drone for traffic survey and queue length survey, and it is confirmed that there is a cost saving effect of 16% ~ 27% compared with the existing method. In the road condition survey, we propose the use of drones for road surface linear survey, geometry survey, and obstacle survey, and it was confirmed that the cost reduction effect is 39% ~ 93% compared to the existing method. CONCLUSIONS : In addition to overseas business, it is expected that it will have a positive effect on research time and cost reduction by using drone in traffic survey in domestic area where labor supply is not easy or basic data is insufficient.

Why does e-Learning service for individuals remain in the early development stage? To find the answers of this question, we adopted usefulness and intention to continued use as dependent variables based on technology acceptance model and inferred convenience, cost-effectiveness, social presence, interactivity, concentration, and procrastination as independent variables based on literature review and interview with e-Learning users. Convenience and cost-effectiveness of e-Learning tend to enhance usefulness and/or intention to continued use, while lack of social presence, interactivity, and concentration of e-Learning and academic procrastination tend to hinder usefulness and/or intention to continued use. To prove this research model, we used a data set collected from the survey. The respondents of survey were the undergraduate students who used voluntarily e-Learning. Data analysis was conducted using 275 respondents by partial least square. The analysis result of causal relation indicated that convenience and cost-effectiveness influenced both usefulness and intention to continued use, and that cost-effectiveness and concentration influenced only intention to continued use. But, interactivity and procrastination did not influence usefulness and intention to continued use.

This study intended for Cheongryongsan Community Garden in Gwanak-gu, one of the demonstration places for 'Community Garden' Project recently implemented by the Seoul Government. This study had two major purposes: investigating the current status of the management and usage and identifying its characteristics; investigating users' awareness to consider the construction and operation directions of sustainable community gardens. This study was conducted based on several surveys such as an investigation into the spatial configuration and the management system of parks through a field study, a use survey through a questionnaire survey for vegetable garden users and an awareness survey about the construction direction of gardens direction preferred by users through the analytical hierarchy process (AHP). As a result of a questionnaire survey for vegetable garden users, the usage status was summarized as follows: Considering the common trends in the 2012 and the 2013 user survey, women used Cheongryongsan Vegetable Garden more than men. Over fifties used it most of all users. Users were mostly neighborhood residents. They used to visit there three to five times a week and stayed for about 30 minutes to one hour. Users differently responded to the question related to the order of priority for the use of the garden in the 2012 and the 2013 survey. They had increasingly used it for individuals' production activities more than social exchanges. As a result of making an AHP analysis for general park users, vegetable garden users there were clear differences in the targets which each subject put emphasis on in relation to the construction and operation of vegetable gardens. General park users recognized a vegetable garden as a park where park functions and the functions of the vegetable garden coexisted. On the other hand, vegetable garden users viewed it as a space where they attached importance to the functions of the vegetable garden like an allotment. Last, this study contemplated subjects related to the construction and operation of vegetable gardens which had to be considered in the future. Vegetable gardens tended to be biased as personal hobby places. It was viewed that the main reason was insufficient support activities for vegetable garden education and exchange programs originally planned when vegetable gardens had been constructed. Vegetable garden users recognized vegetable gardens as places for individuals' farming activities like allotments. For the desirable operation of vegetable gardens, it would be necessary to give priority to the park management before the production activities in individuals' vegetable gardens. The important role of the government would be to build the base through the provision of education and opportunities so that a local resident organization could actively participate in the management of a vegetable garden after a vegetable garden was constructed. It would be necessary to make a use survey and an awareness survey for users conducted in this study on a regular basis because the surveys could be important basic data in the decision-making process for the sustainable operations of the vegetable garden.

The purpose of this survey was to examine the trend, purpose, and overall needs on the use of music by the baby boomer generation. On 87 participants aged from 57 to 66 living in five cities of Korea, online and offline surveys were conducted. As a result, first, the baby boomer generation mostly listened to popular music on their mobile phones when taking a rest alone, and it has been confirmed that the purpose of music use was for happiness, hobby, confidence, and fulfillment in order. Second, there was shown that the baby boomer generation hope to do singing and lyric-discussion in a club setting. Third, for the purpose of music use according to genders, there was found that female participants more significantly focused on volunteering than male. It is meaningful that this study could provide basic data to develop music programs considering characteristics of the baby boomer generation.

Objectives : This study aimed to analyze characteristics of the Korean Medicine users aged 19-39 years, the determinants of Korean Medicine use and effects of Korean Medicine use experience on behavioral intentions among youths. Methods : We studied Korean Medicine Utilization and Herbal Medicine Consumption Survey(2017) data set by complex-sample survey data analysis. In order to derive the characteristics of younger users, Rao-scott χ² test and t-test were conducted. Through multiple logistic regression model adjusted by general characteristic variables, the determinants and behavioral intentions of the Korean Medicine utilization among youths were derived. Results : Fist of all, young users and non-users have significant differences in socio-demographic characteristics and perception on Korean Medicine. Among the general characteristic variables, region, age, marital status, occupation, chronic disease, and private health insurance plans had an effect on the Korean Medicine use in young people(Model II). And adjusted by general characteristic variables as control variables, awareness of Korean Medicine and perception of safety of herbal medicine were deduced as determinants of Korean Medicine use(Model III). Secondly, Korean Medicine use experience increased intentions to use and recommend Korean Medicine services(Model IV-1, 3). Conclusions : In order to increase the use of Korean Medicine among young people, Korean Medicine institutions should strive to increase users' satisfaction, and public health insurance coverage for Korean Medicine services needs to be expanded.

The use of a low-frequency cave radio can also verify survey accuracy. A receiving unit on the surface can pinpoint the depth and location of a transmitter in a cave passage by measurement of the geometry of its radio waves. A survey over the surface from the receiver back to the cave entrance forms an artificial loop with the underground survey, whose loop-closure error can then be determined. In the past, caves were reluctant to redraw complex cave maps after detecting survey errors. Today, computer cartography can automatically redraw cave maps after data has been corrected.

Purpose - The general objective of this study is to explain the governance mechanisms of relational exchanges by considering both economic and relational factors. As regards the relationship between opportunism and governance mechanisms, opportunism was hypothesized as being positively related to the use of the authority mechanism, and negatively related with use of the trust mechanism. Research design, data, and methodology - Purchasing relationships between original equipment manufacturers (OEMs) and their component suppliers were chosen as the empirical setting. Purchasing specialists in each company, who interact regularly with suppliers and have the major responsibility for managing the exchange relationships with suppliers, were used as the respondents for this study. A mail survey methodology was employed to collect data in the final field survey. Results - As predicted, opportunistic behavior is found to be negatively related to the use of the trust mechanism and positively related to the use of the authority mechanism. Therefore, the result supports the proposed hypotheses. Conclusions - By integrating research streams, this study contributes to the marketing discipline by improving our understanding of when and why different mixtures of governance mechanisms are used.

This study was conducted to investigate that the nutrition labeling use is associated with demographic and psychosocial factors according to each nutrition information on the nutrition labeling in Korean adults. The study subjects (N=1,140) were individuals who were aged 20 years and more and answered on the question of nutrition label use and who participated in the Korean National Health Examination and Nutrition Survey (KNHANES) in 2010.As age older, there was more interest in information such as sugar, protein, fat, cholesterol than calories. In contrast, as age younger, there was more interest intrans-fat, sodium as well as calories. As higher education level, there were more aware of trans-fat, sodium and calories. From the result that the most interested nutrition items were significantly different by democratic factors, we could understand interested nutrient information on the nutrition labels could change according to individual specific education. Therefore, this can also provide basic data for systematic education program by nutrition label use.
