Fuel economy label will be used as a national indicator in energy management, leading to the development of car technology manufacturer and plays a role in providing consumer vehicle purchase information. But the government's fuel economy label is continued consumer complaint is different and diminishing fuel economy were introduced by the government to measure the exact fuel economy label than resetting the 5-cycle test method in the US for the domestic vehicle standards. Originally two test mode in order to reduce the impact of the sharp increase in the resources required but methods of calculating a measured result value by driving all of the five test mode a variety of environmental conditions and the running pattern is reflected to the fuel economy label (city( FTP-75 mode), highway(HWFET mode)) and using 5-cycle correction formula for calculating a fuel consumption value and the equivalent value to calculate the result of the 5-cycle test. The compensation was calculated expression 30s, 5-Cycle Test Method of vehicles in 2011 was considered necessary to review the existing 5-cycle correction formula for the New Type car due to the recent rapid development of automotive technology. In this study, recent technology is targeting 14 units New Type car applied over the same test method and the existing check test mode specific fuel economy properties and, as a result of analyzing the corrected expression differences that have already been developed with the existing test vehicle resulting large did not show the difference was found to correction formula also not getting the existing fuel correction expression significant effect on the improvement of the current automobile technology as a maximum error of less than 1.5%.

In recent years Mag-Geol-Li is becoming popular again and the consumption layer of Mag-Geol-Li is definitely younger. Nowadays, Mag-Geol-Li is the main traditional alcohol and without consideration of ages and genders whoever can enjoy Mag-Geol-Li. Producers should ensure fair price of goods and improve production facilities to maximize products to meet the needs of consumers who will buy. In the studies I discuss about the ways to improve the distribution of Mag-Geol-Li, the theories about Mag-Geol-Li, Social backgrounds and effects of Mag-Geol-Li why it is becoming popular and improvement of the distribution structure of Mag-Geol-Li and impact of big Mag-Geol-Li company in Mag-Geol-Li industry. Lately, people can enjoy Mag-Geol-Li without burden because of low alcohol. It is gaining a good response by consumers because Mag-Geol-Li contains lactobacillus, yeasts and dietary fiber, also it is well balanced with nutritional aspects. There are not only huge factory to produce Mag-Geol-Li but also most are still cottage industry. Therefore, quality management does not work well because the majority of Mag-Geol-Li is small businesses. In spite of there are a lot of ways to improve the distribution structure and problems of Mag-Geol-Li, but none provide any improvement that make consumer awareness about the main cause of the problem is inaccurate. The ultimate goal of improving the distribution structure of Mag-Geol-Li is activating the market, the improvement of production facilities and safe for consumers with affordable price and good quality product. As mentioned above, to improve and change the logistics systems and hygiene, government support is required and Mag-Geol-Li companies should be recognized the distribution system as a major problem.

The price of land in Jeju is reaching a new high every day and this phenomenon not only causes real difficulties for the purchase of real estate by local residents, but also results in psychological deprivation. Therefore, this study analyzes the factors causing the increase of the land price in Jeju, in order to examine the measures required to stabilize the land price which is continuously rising. As a result of this study, we developed a land price prediction model including seven variables, including the 'inflation rate', 'interest rate', and 'population'. According to the model, land prices in Jeju are expected to rise steadily, and it is predicted that in 2020 the price will increase to 170% of that in 2015 and will triple by 2025. Based on the results of this study, this study suggested policy alternatives, such as 'Establishing a tourism policy for managing the number of tourists' and 'increasing the approval standards for development activities'. The two policies proposed in this study can be implemented as a regional initiative, which may be less effective than the changes in the national system, but it is meaningful that the efforts to stabilize the land price will continue at the regional level.

Recently, the research and development of weapon systems have expanded from ILS centered on acquisition costs to LCS, including operating maintenance costs. Regulations define the provision and formula of operating maintenance costs, but this does not consider the characteristics of the design and operation/maintenance of real weapon systems based on engineering calculations. Therefore, this study suggests a simulation design method to complement these areas and produce more accurate operating maintenance costs. The research procedures are as follows. First, the provision and formula of operating maintenance costs were defined to make the simulation results applicable. Second, a simulation model was developed by reviewing design considerations so that the simulation results reflect reality more accurately. The design considerations include the PBS of weapon systems, operation schedules, specifications for operation/maintenance/warehouse facilities, and basic cost information (personnel expense and spare part/equipment cost). This study is expected to be effective in calculating the operating maintenance costs more easily and accurately.

Most of current internet auction systems are single auction server program that partly automates the function of the conventional auction house. So these systems do not provide sufficient independence, distribution and parallelism between the functions of the conventional auction house. In these suction systems, only some of suction management facilities are automated by the server program, but still users need to execute a repetitive task to monitor the dynamic progress of a certain auction, decide the proper bid price, and submit the bid. Another problem is that they support only the single auctions such as English suction and Dutch auction, but they do not support the double auctions that are superior to the single auction in terms of speed, efficiency, and the fair distribution of profit. In this paper, we present are design and implement of an agent-based continuous double auction system, called CoDABot, in order to overcome the limitations of current auction systems. CoDABot supports the continuous double auction, provides various bidding agents for users to select, and has been implemented with a multi-agent system to realize more independent, and parallel subsystems.

This study was to investigate the association among satisfaction of nutrition labeling, change of purchase behaviors, and dietary life care, based on the awareness of nutrition labeling at expressway rest areas. The subjects (n=903) were divided into two groups, according to the awareness of nutrition labeling: Awareness of Nutrition Labeling (ANL) group, n=367; Non Awareness of Nutrition Labeling (NANL) group, n=536. Effort of health care and identification of nutrition labeling was significantly higher in the ANL group, compared with the NANL group. As for the main reason for not identifying nutrition labeling, 'not interested in nutrition labeling' was the highest in the ANL group, and 'Don't know nutrition labeling is provided' in the NANL group. Identification ratio of nutrition labeling in future was significantly higher in the NANL group, compared with the ANL group among the subjects who didn't identify nutrition labeling before. After their becoming aware, a change of food purchase after reading the nutrition labeling was significantly higher in the ANL group, compared with the NANL group. Health beliefs on the nutrition labeling were significantly higher in the ANL group, compared with the NANL group. Satisfaction of nutrition labeling was also significantly higher in the ANL group, compared with the NANL group. The ANL group also expressed a necessity of expansion of nutrition labeling, compared with the NANL group. In the ANL group, identification of nutrition labeling was significantly higher in the hard effort group, compared with the little effort group of dietary life care. Therefore, improvement and campaign of nutrition labeling for consumers at expressway rest areas, especially for the NANL group, will be effective in identifying nutrition labeling for their health care.

The purpose of this study was to determine the impact in visitors' spending on two separate local festivals, and to present the improved market strategies to attract visitors to revisit the local festivals. This study was also intended to suggest the ways to increase the competitiveness and revitalize the local festivals by improving the existing attractions and creating new attractions based on the visitors' evaluation. On the purpose of the study, we studied the visitors of two local ricefests, Icheon Rice Cultural Festival and Rice Festival in Jincheon Chungbuk, and estimated the determinants influencing the visitors' spending to the festivals by applying Tobit model. Finally, to estimate the behavioral differences in visitors of the two festivals, we compared the estimated determinants for the visitors of each festival by using Log-likelihood Ratio, and analyzed the differences in the factors influencing the visitors' spending. Summarizing the propensity of visitor's spending to local festivals, visitors of two rice festivals buy or tended to buy things on impulse. Therefore, festival industry needs to take measures to efficiently accommodate their expenditures from the stage of designing festivals.

The purposes of this study are to examine the adolescents' consumer knowledge and consumption behavior and analyze the factors affecting them. The sample of this study is 640 middle school students living in kyunggi province. The data are collected using structured questionnaires and analyzed by the descriptive statistics, t-test, One-way ANOVA and multiple regression analysis. The results of this study are as follows. First, the third grade students and the female students get higher scores in the consumer knowledge compared with the first grade and the male students. Other factors affecting the level of consumer knowledge are occupation of parents, education level of mother, household income and GPA. Second, the consumption behavior of students is moderately resonable and affected by sex and grade of students, education level of mother, household income, and GPA. Third, the adolescent's consumer knowledge affects their consumption behavior. The results of multiple regression analysis show that 4% to 9% of variances of sub categories of the consumption behavior are explained by the level of consumer knowledge. Since the consumer knowledge learned at schools is rarely transferred to the reasonable consumption behavior, the systematic and relevant consumer education considering the development stages of adolescents is required in the future.

The concept of customer satisfaction is very important issue in the service firms. All service firms should delight theirs customers? Which service contexts creating customer delight results in better positive performance? This study is to examine the moderating effect of service type on the customer delight-behavioral intention relationship. Data from consumers across two distinct service contexts (retail banks and upscale restaurants) were obtained. Using the multiple moderating regression analysis, the proposed hypotheses in this study were tested. The results reveal that customer delight had a greater positive impact on both revisit and referral intention in the hedonic service than the utilitarian service. This study suggests specific service contexts where customer delight strategies generate better desirable results. The customer delight strategy is able to be applied in both hedonic and utilitarian services, but it is more effective to lead customer loyalty in the hedonic service than utilitarian services. Service firms need a strategic approach to customer satisfaction strategies. This study provide strategic implications for service firms to efficiently manage and allocate resources, and can help them in making decisions about establishing and implementing customer satisfaction strategies.
