In this study, based on previous research on personal broadcasting, we indirectly measured content quality, YouTuber attributes, user satisfaction, and behavioral intention, which are latent variables that cannot be directly measured, as measurement variables, and then measured theoretically between the latent variables. In order to analyze the causal relationship, we used a structural equation model to determine to what extent the content quality of the YouTube mukbang channel and the YouTuber's attributes influence behavioral intentions such as purchase, recommendation, and continued use according to viewers' satisfaction with use. We intend to analyze and verify the relationship between related variables. The research results are as follows. First, the value, relevance, timeliness, completeness, and data quantity of content quality were found to have no significant impact on user satisfaction. Second, the trustworthiness, expertise, attractiveness, and intimacy of YouTuber attributes were found to have a significant impact on user satisfaction, but the similarity of YouTuber attributes did not have a significant impact on usage. Third, user satisfaction was found to have a significant impact on behavioral intentions and purchase intentions. However, user satisfaction was not found to have a direct significant impact on recommendation intentions or continued usage intentions.

Water quality investigation was conducted for small/medium sized reservoirs in A city in June and November 2014 as a preliminary step for further use. Water quality analysis experiments were conducted for 21 reservoirs managed by a local government and water quality data were obtained from Korea Rural Community Corporation for 12 reservoirs. It was found that relatively poor water quality, not satisfied with the regulation level (somewhat poor(IV)) for agricultural use, was observed for some reservoirs and worse water quality (poor(V) and very poor(VI) grade) was observed for more reservoirs during autumn /winter season due to the decrease in water volume. Correspondingly, the trophic state was obtained as "Eutrophic" or "Hypertrophic" using the Korean trophic state index for most reservoirs. It was also revealed that significant contamination in sediments was not observed for selected 8 reservoirs considering water quality in each reservoir. The results in this study could be useful for the use of small/medium sized reservoirs as alternative water resources, tourism resources, inland fishery resources, renewable energy production sites, and anti-flooding reservoirs.

People spend most of their time inside buildings recently, so the indoor air quality is one of the most important factors to human health. Furthermore, minimum energy use with proper ventilation systems for pleasant indoor environment is necessary because of energy shortage over the world. The concern to maintain proper indoor air quality at home has been increased, and a proper indoor air quality is continuously requested by the residents. By measuring and analyzing the density fluctuation of $CO_2$ through indoor humidity and testing personal reactions regarding comfort condition, we can obtain a way to effective ventilation. Heat and carbon dioxide emissions from resident's metabolism and construction materials could be the causes of indoor air pollution. If these materials stay indoors for a long time, it could directly influence the resident's health condition with diseases. It also leads massive energy use. Therefore, the way to save energy and to have effective control of indoor ventilation is needed. This study presented the control method of bedroom ventilation by $CO_2$ concentration change and subjective evaluation.

The purpose of this study were to identify the different farming styles of red pepper growers, to describe their characteristics and to get some implications far planning the agricultural development strategy in the area. The researcher surveyed quantitative and qualitative data through interview with researcher developed questionnaires from selected 99 farmers in Eumsung county, Chungbuk province, Korea. The researcher found the low types of red pepper farming: 'red-pepper-centric middle farmers', 'diversified larger farmers', 'red-pepper-dependant small farmers', and 'small farmers for own use'. Based on the above findings, the researcher could derive some implications as follows. Firstly, the difference of market strategy and marketing efforts among the four farming styles should be regarded as important considerations when planning the agricultural development strategy in Emsung county. Secondly, the cooperatives' red pepper marketing strategies in Eumsung county were focused on the processed red pepper products sold at middle or low priced by big retailers in urban areas. Therefore, the cooperatives should change their view point of quality, if they want to initiate the planning process of 'the production and marketing high quality red pepper'. Thirdly, the major efforts of Eumsung county Agricultural Technology Center (ATC) made efforts on increasing the productivity of red pepper farming, however, the technologies recommended by the ATC for farmers required more cost and labour especially for 'red-pepper-dependant small farmers' and 'diversified large farmers'. The ATC should make efforts to find new technologies for helping 'red-pepper-dependant small farmers' to reduce the use of pesticides and 'diversified large farmers' to use the regional images effectively for marketing their hish quality red peppers.
