The purposes of this study was to identify the level of satisfaction with the food quality in a company cafeteria located in Daejon. 400 people were given questionnaires, of which 341 questionnaires were returned for analysis (90.25% response rate). Our results show, 85.63% of customers eat at the cafeteria more than 3~4 times per week. 48.68% of people surveyed chose their meal based on the proximity when they enter the cafeteria. 39.59% said the most important factor for eating at the cafeteria was taste. 33.72% said it was quality. The type of food that was leftover the most was 'Guk' (soup). 52.20% said 'Guk' was leftover due to the awful taste. Food quality (34.60%) and taste (34.02%) required the most improvement according to those surveyed. Additionally, we divided food quality into 3 factors: 'sanitation & service', 'food', and 'menu composition'. People who marked down 'no other place to eat' was the reason they ate at the cafeteria also had the lowest satisfaction scores across all items (p<0.001). Improving the 'Guk' and 'meat' was rated as the most important criteria to improve satisfaction with leftover food. Unsurprisingly, the 'taste' of leftover food had the lowest satisfaction scores. Those who had the lowest quality satisfaction scores also wanted to improve 'taste', 'quality' and 'sanitation' the most (p<0.001). Based on these findings, the foodservice manager can increase the overall satisfaction with the cafeteria food by focusing on improving the taste, quality and sanitation of the food that it serves.

Vacuum chambers have wide application for a variety of purposes such as material processing, vacuum gauge calibration, etc. As the dynamic pressure generated in such chamber is non-uniform, in many industrial as well as research processes, it is vital to know the non-uniform gas distribution with associated gas flow regimes and the ways of minimizing these pressure non-uniformities. In the present work, the behavior of gas flow in a vacuum chamber, during continuous gas flow, is described in the pressure range 0.1-133 Pa and the effect of baffle plate in minimizing the pressure non-uniformities is investigated. It was observed that maximum deviations in the pressure occur near the gas inlet point and that the effect of baffle plate in minimizing the pressure non-uniformities is more obvious in the transitional flow regime.

Since discount stores should be operated mostly by the non-human resources regarding the natural characteristics of the business, it is possibly said that their physical environments have been extremely significant. This study attempts to develop the measurement items and construct factors which are especially relevant to the physical environments of the discount stores and examine how the customer satisfaction and intention influence on these construct factors. These provide a useful framework for understanding the problems of measuring and evaluating the physical environments of discount stores. The final factor analysis for each construct factors resulted as four factors, and two categories(amenity and convenience) represented the characteristics of same construct such as the visibility. Then convenience is eliminated, and an attempt was made to add the new variable what is called the visibility. As a result, final construct factors that would be used in this study are made of four items; amenity, accessibility, POP and visibility. This study utilizes the LISREL 8.12 to evaluate the validity of factor structures and measurement model involving the physical environment in discount store. Finally, for the success of the projects, I think that it is necessary to provide comprehensive efforts continuously.

Since disaster-safety accidents cause serious damage to human life and property, preparations and responses have been critically challenged by the country and industry. Recently, the government and industry have recognized its importance and are seeking solutions to the causes of disasters in various ways. If virtual reality technology is actively used, it will be easier to prepare and train for disasters, as the social costs will be reduced. However, academic research on this has not been actively studied. In particular, it seems difficult to seek data that comprehensively analyzes or organizes disaster-safety with virtual reality contents. In this paper, we analyze the current status of domestic and overseas focused on virtual reality disaster/safety contents, examine its characteristics, and point out the direction required for advanced service in the future. To this end, the implications of the numerical data of the accident type have been derived, and the direction of development of public institutions, academic research, and industry have also been investigated. Finally, technical considerations are presented as well.

As the national demand for solving the fine dust problem has increased, the government has announced intensive measures to deal with fine dust. So recently, selective catalytic reduction(SCR) has attracted attention as a technology for removing nitrogen oxides from precursors of fine dust. In this study, the government's policies related to fine dust and the current status of market and R&D were investigated, and economic analysis by scenarios was conducted by dividing cases where SCR technology was applied to industries. The results of economic analysis for each scenario were calculated using NPV, and companies with no denitrification facilities(Case 1) introduced general SCR technologies(Scenario 1-1) and low-temperature SCR technologies(Scenario 1-2). In addition, companies that have already installed denitrification facilities(Case 2) analyzed the two categories, using the general SCR technology as it is(Scenario 2-1) and replacing it with low-temperature SCR technology(Scenario 2-2). Comparative analysis was performed based on the results of each NPV.

The upturn of Korean nuclear power program can be considered to have started in early 70's while future plants for the construction of new nuclear power plane virtually came to a halt in United States. It is projected that power plant systems from combination of nuclear and coal fired types might shift to all coal fired type, considering the current trend of construction on the new Plants in the United States. However, with the depletion of natural resources, it is desirable to understand the utilization of two competitive utility technologies in terms of invested energy. Presented in this paper is a comparison between two systems, nuclear power plant and coal fired steam power plant in terms of energy investment. The method of comparison is Net Energy Analysis (NEA). In doing so, Input-Output Analysis (IOA) among industries and commodities is done. Using these information, net energy ratios are calculated and compared. NEA is conducted for power plants in U. S. because the availability of necessary data are limited in Korea. Although NEA does not offer conclusive solution, this method can work as a screening process in decision making. When considering energy systems, results from such analysis can be used as a general guideline.
