Despite expansion of the mulnaengmyeon market, there have been no studies on consumers' attitudes towards mulnaengmyeon. The purpose of this study was to investigate the usage and consumption patterns for mulnaengmyeon among adults in the Seoul metropolitan area of Korea. A survey including demo- and socio-graphics, general mulnaengmyeon usage, and consumption questions was tested on 210 consumers. The results of the survey showed that the majority of consumers consumed mulnaengmyeon more frequently during summer. Although the instant mulnaengmyeon market has rapidly increased, it was found that mulnaengmyeon is a food that is generally consumed in restaurants. In addition, mulnaengmyeon usage and consumption patterns significantly differed according to consumer age, whereas there was no difference observed according to parent's or grandparent's hometown of origin. Older consumers were observed to consume and purchase mulnaengmyeon as well as instant mulnaengmyeon more often than young consumers. Also, older consumers were shown to consider "health" related factors as more important when selecting mulnaengmyeon, whereas young consumers considered "price" related factors to be more important.

Purpose - Recently, many large retailers have been frequently purchasing commercial brands. Not only the quality of products purchased but also the brand images are of concern in this process. Based on this rising trend, commercial brands have become an important issue in the retail business world, along with increasing general interest as well. Thus, this study focuses on the factors affecting commercial brand images and clarifies the impact of the resulting factors as well. First, store images and familiarity, price sensitiveness, and knowledge are presented as the effect factors for commercial brands. Second, the study tries to clarify the effect of commercial brand image on the reliability and loyalty of customers. Research design, data, and methodology - To conduct the study methodology, 250 questionnaires were distributed to retailers who have used large discount stores located in Busan to purchase a commercial brand a total of 234 valid questionnaires were used in the final analysis. To verify the hypotheses, a structure equation formula using Amos 20.0 was calculated. First, prior to the verification of hypotheses, the reliability and feasibility of the questions were tested, and as a result, the value of Cronbach's alpha was higher than 0.7, thereby showing reliability. Additionally, for the verification of the feasibility of the questions, a confirmation factor analysis was implemented. Results - First, variances such as store images, familiarity, price sensitivity, and knowledge were presented as the factors of effect on commercial brands. As a result of the hypotheses verification, all the effect factors presented in this study were confirmed as important variables of commercial brand images. The hypotheses were drawn based on the studies relating to existing commercial brands, and thereby, a result similar to previous studies was produced. However, the effect factors of the commercial brand image presented in this study shaped a new study model based on the previous studies. Second, it was found that commercial brand images had positive effects on the reliability and loyalty of customers. This study presented reliability and loyalty as the resulting factors of commercial brand image because they are the most important factors in relation to customer behavior and variables that can suggest marketing points for distribution businesses. Conclusions - This study focused on clarifying the factors that are important effect factors for commercial brand images. As a result, all the hypotheses were confirmed in this study, indicating a meaningful result, and thereby suggesting many points that can be presented to distribution businesses. First, the proper strategies should be developed based on the hypothesis that a store image, the familiarity of customers with brands, and the price sensitiveness and knowledge level of customers have an important effect on the choice of commercial brands. Additionally, the formation of such favorable images will have positive effects not only in terms of customer trust in the commercial brands but also in terms of their loyalty.

A number of the retail and traditional market customer is decrease, whereas that of the supermarket in department-store customers in is increase. This case suggests that customers have a preference for much more comfortable and pleasant shopping places And making a resonable purchase in the supermarkets where we can find various goods and price zone, is now garden variety. It is a current course that once the manager ask an architect for multi-functional space design in department-store and then the architect compose a team and start to design. Of course, the team of planner thinking manage give the design team the basic material data such as commerce analysis and the use of each layer in the department store but, the design team solve the assignment by architectural form, functional space plan and the limited architecture law. After establishing general design for architecture, we can ask shopping-mall distribution, products display and interior design of the interior design general design for architecture, we can ask shopping-mall distribution, products display and interior design of the interior design team. so it is inevitable that the interior design team concerning M·D can find lots of complementary factors with architecture design. The purpose of this study is analyzing the differences of architecture design, which has to accept the limited law and interior design concerning M·D, satisfying the structure and the law in the future design for the department-store. Also the purpose of this thesis is suggestion the items architects and interior designers research into together to make the inner space ideally.

According to the new climate change agreement, technology development to reduce greenhouse gases is actively conducted worldwide, and research on energy efficiency improvement in the field of power generation and transmission and distribution is underway [1,2]. Economic analysis of the operation method of storing and supplying surplus electricity using energy storage devices, and using energy storage devices as a frequency adjustment reserve power in regional cogeneration plants has been reported as the most profitable operation method [3-7]. Therefore, this study conducted an economic analysis for the installation of energy storage devices in the combined heat and power plant in the Czech Republic. The most important factor in evaluating the economics of battery energy storage devices is the lifespan, and the warranty life is generally 10 to 15 years, based on charging and discharging once a day. For the simulation, the ratio of battery and PCS was designed as 1: 1 and 1: 2. In general, the primary frequency control is designed as 1: 4, but considering the characteristics of the cogeneration plant, it is set at a ratio of up to 1: 2, and the capacity is simulated at 1MW to 10MW and 2MWh to 20MWh according to each ratio. Therefore, life was evaluated based on the number of cycles per year. In the case of installing a battery energy storage system in a combined heat and power plant in the Czech Republic, the payback period of 3MW / 3MWh is more favorable than 5MW / 5MWh, considering the local infrastructure and power market. It is estimated to be about 3 years or 5 years from the simple payback period considering the estimated purchase price without subsidies. If you lower the purchase price by 50%, the purchase cost is an important part of the cost for the entire lifetime, so the payback period is about half as short. It can be, but it is impossible to secure profitability through the economy at the scale of 3MWh and 5MWh. If the price of the electricity market falls by 50%, the payback period will be three years longer in P1 mode and two years longer in P2 and P3 modes.

This study intends to examine the distribution channel of the most popular ten species caught in Korean coastal and off-shore fisheries with the aid of interviewing fish brokers and cooperative staffs in fish landing markets. This paper finds and emphasizes the following three suggestions, in order to improve the present scheme of fish distribution system. Firstly, annual catch of 10 kinds of fishes is successively decreasing in quantity from 1994 to 1998. Moreover annual catch shows larger variations than fish price and cooperative sales quantity. Except sea eel and sole, cooperative sales accommodates more than 90% of the fish landed, accounting for the small variation in cooperative sales, which invalidates the effectiveness of the free distribution system adopted by the government. Secondly, diversified distribution channels are exposed according to the nature of the fish, the method to harvest, and the quantity caught. Large retailers such as discount stores, super chains and home shopping institutions are actively involving themselves in direct purchase in fish landing markets. Through the analysis of distribution routes, the general distribution channel of fresh fish has been found such as producers longrightarrow fish brokers in landing markets longrightarrow fish brokers in central wholesale markets longrightarrow wholesalers longrightarrow retailers longrightarrow consumers. In order to reduce distribution margin through the analysis of distribution function and distribution margin, this paper presents a new distribution channel such as producers longrightarrow fish brokers in landing markets longrightarrow wholesalers longrightarrow retailers longrightarrow consumers. Thirdly, to improve the fish landing markets, this paper suggests the M&A of uneconomical fish landing markets or renovating toward wholesalers, introduction of processing services and improvement of processing facilities, subsidizing fish brokers in landing markets, revitalization of marketing divisions in cooperatives and improvement in fish auction system.

This study investigated the perception of upcycling for sensitive university students in regards to fashion trends. It was conducted through questionnaires delivered to male and female college students who majored in clothing related subjects from June 2012 to June 2013 in Gwangju. The contents for this research are general details, seriousness of environmental resources, awareness of upcycle, and purchasing intention for upcycling products. Most of the respondents said that recycling of resources is absolutely necessary due to the impact of environmental pollution and the consumption of resources. On the contrary, the experience of the respondents which purchased recycling products was low. The awareness of also was low, upcycling, internal upcycling brands and internal consumption groups, however, the decisions for subsequent purchases were positive. The reasons for the unsatisfactory of upcycling of products were due to quality and price. The reaction for many upcycle goods had the best question response rate in daily supplies part; subsequently, this study suggested 3 items, apparel products, fashion accessories, and daily supplies. In addition, a group which contains people who expend more for clothing had a lower awareness of upcycle and purchasing intention than other groups that contained some people who expend less. The results of the study can be used in data that recognize the necessary of upcycle education for university students, and develop educational programs. It can also encourage the purchase of upcycle products that reduce the consumption of resources.

Diet is closely related to an economic level, but few studies have reported on the relationship between the economic level and eating habits, especially in college students. Therefore, this study was conducted to clarify differences in eating habits with a focus on processed foods according to allowance level in college students. This study was a cross-sectional survey of 500 college students using a questionnaire. The questionnaire consisted of general characteristics, eating behaviors, purchase of processed foods, and preference and intake frequency of processed foods. All subjects were classified based on monthly allowance: less than \300,000 (n=149), \300,000~400,000 (n=177), and more than \400,000 (n=124). All survey results were comparatively analyzed among the spending money groups. As the level of spending money of the subjects increased, the rate of skipping meals, eating out, and unbalanced diet increased (P<0.05). The reason for consuming processed foods was because they are easy to prepare. The factor considered the most when buying processed foods was price. However, these results showed no significant difference according to level of spending money. As spending money increased preference for retort, convenience, canned, and bottled foods significantly increased. Intake frequency of dairy products was lower, and the frequency of processed foods was significantly higher with more spending money. This study found that a higher level of monthly allowance in college students, was associated with higher rate of skipping meals, eating out, and unbalanced diet, and the preference and intake frequency of processed foods were also high. These results suggest that spending money level in college students, as an economic indicator, is relevant to intake of processed foods.

The purpose of this study was to analyze University student's dietary behavior for processed foods and recognition on food nutrition labelling according to the degree of health concern. For this study, 302 University students in Gyeonggi region was surveyed by questionnaire from May in 2016 and it included the questions about general matters, dietary behavior on processed foods, and the food nutrition label system. It was analysed by SPSS win 23.0 program. And the results are as follows. According to the result of the factor analysis, the preference of processed foods were showed 3.21~3.97. There were significant differences in milk and milk products preference according to health concern (p<0.05). Also frequency of processed foods was shown significant differences in milk and milk products, noodles, beverage, and fast food (p<0.05), whereas no significant differences were found in meat products, snack, bread and frozen food (p>0.05). Also, the processed food purchase consideration according to health concern was shown significant differences in nutrition, origin, manufacturing company (p<0.05), whereas no significant differences were found in taste, price, exterior, brand, and shelf life (p>0.05). Thus, it is necessary to do continuing public relations and to provide more opportunities for nutrition education so that the University students may obtain right dietary behavior on processed foods and the system of food nutrition indication be established properly.

Online reviews we encounter commonly on SNS, although a complex range of assessment information affecting the consumer's preferences are included, it is general that such information is just provided by simple numbers or star ratings. Based on those review types, it is not easy to get specific information that consumers want and use it to make a decision for purchase. Therefore, in this study, we propose a prediction methodology that can provide ratings broken down by evaluation items by performing sentiment analysis on restaurant reviews written in Korean. To this end, we select 'food', 'price', 'service', and 'atmosphere' as the main evaluation items of restaurants, and build a new sentiment dictionary for each evaluation item. It also classifies review sentences by rating item, predicts granular ratings through sentiment analysis, and provides additional information that consumers can use to make decisions. Finally, using MAE and RMSE as evaluation indicators it shows that the rating prediction accuracy of the proposed methodology has been improved than previous studies and presents the use case of proposed methodology.
