The purpose of this study is to measure the effect of customers’ waiting time on their revisit intention through their emotion. Also this study assessed the effect of restaurant selection attributes on consumers’ revisit intention in Korea. This study used experimental scenario questionnaires for collecting data. Frequency analysis, Cronbach’s alpha, correlation, ttests and multiple regression analysis were assessed using SPSS. Customers preferred taste, sanitation and service when selecting a restaurant to dine out. The results of this study found that there were no significant differences between positive and negative emotions due to waiting time. Findings of this study suggested that waiting time, convenience, nutritional value, and emotion influenced consumers’ revisit intention. Therefore, reducing waiting time and providing proper service will help consumers have positive emotions to return to dine at a restaurant.

With the recent accelerated policy-making and interests in new renewable energy, plans to develop and supply the new renewable energy have been devised across multiple regions in Korea. Solar energy, in particular, is being applied to small-scale power supply in provincial areas, as solar cells are used to convert solar energy into electric energy to produce electric power. Nonetheless, in the case of solar power plants, the need for a large stretch of land and considerable sum of financial support implies that the planning step should take into consideration the most suitable meteorological and geographical factors. In this study, the proxy variables of meteorological and geographical factors associated with solar energy were considered in analyzing the vulnerable areas regarding the photovoltaic power generation facility across the nation. GIS was used in the spatial analysis to develop a map for assessing the optimal location for photovoltaic power generation facility. The final vulnerability map developed in this study did not reveal any areas that exhibit vulnerability level 5 (very high) or 1 (very low). Jeollanam-do showed the largest value of vulnerability level 4 (high), while a large value of vulnerability level 3 (moderate) was shown by several administrative districts including Gwangju metropolitan city, Jeollabuk-do, Chungcheongbuk-do, and Gangwon- do. A value of vulnerability level 2 (low) was shown by the metropolitan cities including Daegu, Ulsan, and Incheon. When the 30 currently operating solar power plants were compared and reviewed, most were found to be in an area of vulnerability level 2 or 3, indicating that the locations were relatively suitable for solar energy. However, the limited data quantity for solar power plants, which is the limitation of this study, prevents the accuracy of the findings to be clearly established. Nevertheless, the significance of this study lies in that an attempt has been made to assess the vulnerability map for photovoltaic power generation facility targeting various regions across the nation, through the use of the GIS-based spatial analysis technique that takes into account the diverse meteorological and geographical factors. Furthermore, by presenting the data obtained for all regions across the nation, the findings of this study are likely to prove useful as the basic data in fields related to the photovoltaic power generation.

We assessed the growth characteristics of Auricularia polytricha ‘Geoni’ cultivated in a simple greenhouse constructed of polyethylene (PE) without air conditioning (high temperature) and in an air conditioned mushroomhouse. The successful cultivation of A. polytricha ‘Geoni’ at high temperatures can reduce energy and facility investment costs. The comparison of growth characteristics of the fungi grown under the different temperature conditions revealed that fruit bodies were larger in the higher temperature condition, but were brighter in the lower temperature condition. Additionally, fruit body physiology was found to be not affected by temperature. In the PE greenhouse, the fresh weight of fruit body was higher in mid-June and early July. Therefore, it was possible to effectively control the growth period of the mushrooms during a high-temperature period. The findings indicate the potential to cultivate A. polytricha ‘Geoni’in a simple PE greenhouse that is not cooled in summer, thus reducing energy costs.

Experiments of local cooling and heating on crown and root zone of forcing cultivation of strawberry ‘Seolhyang’ using heat pump and root pruning before planting were conducted. During the daytime, the crown surface temperature of the crown local cooling treatment was maintained at 18 ~ 22oC. This is suitable for flower differentiation, while those of control and root zone local cooling treatment were above 30oC. Budding rate of first flower clusters and initial yields were in the order of crown local cooling, root zone local cooling and control in root pruning plantlet and non pruning plantlet, except for purchase plantlet. Those of root pruning plantlet were higher than those of non pruning plantlet. These trends were evident in the yield of the first flower cluster until February 14, 2018, and the effect of local cooling and root pruning decreased from March 9, 2018. The budding rates of the second flower cluster according to the local cooling and root pruning treatments were not noticeable compared to first flower cluster but showed the same tendency as that of first flower cluster. In the heating experiment, root zone local heating(root zone 20oC+inside greenhouse 5oC) and crown local heating(crown 20oC+inside greenhouse 5oC) saved 59% and 65% of heating fuel, respectively, compared to control(inside greenhouse 9oC). Considering the electric power consumption according to the heat pump operation, the heating costs were reduced by 55% and 61%, respectively.

Using virtual reality technology, users can learn and experience many interactions in virtual space like the actual physical space. This study was conducted to develop air flow simulator that allows farmers and consultants to consult air flow through VR devices by creating a greenhouse or pigpen model. It can help educate farmers about the importance of ventilation effects for agricultural facilities. We proposed CFD visualization system by building a virtual reality environment and constructing database of CFD and structure of agricultural facilities. After consultants can set up situations according to environmental conditions, the users experience the visualized air flow of agricultural facility according to the ventilation effects. Also it can provide a quantified environmental distribution in the agricultural facility. Currently, the CFD data in agricultural facilities are established during winter and summer. In order to experience various environmental conditions in the developed system, The experts need to run CFD data under various environmental conditions and register them in the system requirements.

The drinking water supply system applicable to the laying hen consists of air-water heat pumps, drinking water tanks, heat stroage tank, circulation pumps, PE pipes, nipples, and control panels. When the heat pump system has power of 7.7 to 8.7 kW per hour, the performance coefficient is between 3.1 and 3.5. The supply temperature from the heat pump to the heat stroage tank was stabilized at about 12±1°C, but the return temperature showed a variation of from 8 to 14°C. Stratified temperature in the storage tank appeared at 12.°C, 13.5°C and 14.4°C, respectively. The drinking water supply temperature remained set at 15°C and 25°C, and the conventional tap water showed a variation for 23°C to 30°C. As chickens grow older, the amount of food intake and drinking water increased. y = -0.0563x2 + 4.7383x + 8.743, R2 = 0.98 and the feed intake showed y = -0.1013x2 + 8.5611x. In the future, further studies will need to figure out the cooling effect on heat stress of livestock.

Product replacement (PPL) is used widely in marketing and plays crucial roles but the effects of the PPL attributes on a restaurant brand are not well known. Therefore, this study examined the effects of PPL attributes on brand awareness and brand credibility. In addition, the relationship among brand awareness, brand credibility, and brand loyalty was investigated. The study found that the characteristics of PPL, such as information and entertainment, affected brand awareness. On the other hand, inconvenience did not have any impact on brand awareness. In addition, information, entertainment, and inconvenience affected brand credibility. Furthermore, brand awareness and credibility influenced brand loyalty significantly. These results suggest that PPL can be a very effective way to advertise. Hence, PPL should be done with a sense of information and entertainment than simply with more frequent exposure to consumers, which that might cause inconvenience.
