This study analyzed the effects of the relational norm factor of food service franchising on the intention to remain, in view of the importance of relational norms, as antecedent variables, to franchisees' perceived fairness to enhance the competitiveness by formation of long-term relationship between interested parties to food service franchising, the franchiser and the franchisee. According to a questionnaire survey, more than 100 franchisees that recorded three business years in Seoul, Incheon and Gyeonggi area were selected for convenience sampling. Then, among them, 515 effective samples were analyzed. For statistical data, detailed types of analysis were performed by using AMOS 17.0, such as factor analysis, exploratory factor analysis, confirmatory analysis and frequency analysis. The purpose of this study was to examine the relationship between the franchiser and the franchisee by arranging relational norm factors for the relationship to be suitable for the current situation of Korea, instead of Western-style theory-based relationship marketing, and by understanding a connection between perceived fairness and management achievement-related variables, and to make a conceptual framework for building a positive relationship between the franchiser and the franchise in future food service franchising industry. Moreover, it aimed to increase franchisee satisfaction and results including re-contract according to perceived positive relationship value on the franchiser and to make contribution to find and show the proper direction for development of the Korean-style food service franchising system.

Many researches have been carried out consistently for the green ship owing to its economic increasement, efficiency and convenience. One of them is an electronic controlled marine diesel engine. However, we are suffered from dissemination of above engine, due to its anxiety about safety and reliability. In order to solve these problems in this study, emission characteristics test of main propulsive two-stroke diesel engine, equipped both electronic control and cam drive fuel injection systems, has been performed and evaluated under the various load conditions. From the test results, we have confirmed that exhaust gas emission characteristics of the electronic control system is similar to the cam drive system in eco-mode operation, but NOx in emission mode has been decreased 100ppm or more in full load condition. HC emission from the electronic control system is decreased 10~20ppm at 50% load, and 35~40ppm at 25% load in comparison to cam drive system. In fuel consumption, it is considered that 7g/kWh is decreased than the value of cam drive system at 700bar of injection pressure, which is 200bar higher than cam drive system.

Expo, as one of the types of convention, is defined as the exhibition of which primary object is the public enlightenment. It displays lots of exhibits from countries around the world created or produced by advanced technologies, but its priority is actually on suggesting value of product, usability and creativity, not on seeking for purchasers of those products. Thus, the world's event Expo can be deemed as the place for educating visitors with various features in both current and future generation in terms of "experience". This study intends to grasp the attributes and elements of the host cities and to look into the formation of city image after being a spectator and the relation for suggesting systematic and rational measures on planning and promoting the Expo. For the foregoing measures, this study suggests effective management measures for Expo spectators by disclosing attributes of host cities, relationship with the formation of city images, and satisfactory relationship among Expo spectators. For achieving the purpose of this study, the relationship between spectators who visited the 'Cheonan 2009 Wellbeing Food Expo' and each element on the basis of the measuring devices deducted through a preparatory research. Based on the results deducted through positive analysis, it intends to expect qualitative improvement of 'Cheonan 2009 Wellbeing Food Expo' and to suggest measures for elevating satisfaction level of Expo spectators by displaying alternative elements for spectators' choice at the Expo and gives continuous suggestion on managing spectators.

Game character customizing has evolved with the desires of users who want to enjoy the scarcity value; thereby, the category which is subjected to character customizing is extending. However, despite such a great interest, character customizing interface has been created for the sake of the convenience of each game developing company, without proven guidelines. The confusion of designers who create interface is caused by using independently created interface without testing the optimal form of interface according to manipulative activity which integrates game character customizing interface, and this confusion leads to the discomfort of users. All the more, studies on character customizing have been mostly concerned with the preference for certain characters according to user propensity or character producing methods. Therefore, basic research into interface relative to character customizing is insufficient. Accordingly, through the development of universal guidelines appropriate for game character customizing interface. the discomfort of users is to be removed. This paper conducted an investigative analysis of the current interface of games which support character customizing, and classified the type of interface. Then, the paper researched 16 types of games that support character customizing out of games ranked within top 50 in the on-line game ranking. As a result of the analysis, the characteristic feature of every game appeared in the offer of detailed optional factors. Those detailed optional factors could be classified, to some extent; however, their manipulative interfaces were discovered not to be classified into different types. The results of this paper will be used as an analytic system in the preparation of the guidelines of game character customizing interface, down the road.

This study examined the effectiveness of and satisfaction of visitors with the Environmental Improvement Project on national parks' trail entry areas. A survey was conducted to improve the proposal framework based on the data. Data for the study were obtained from 6400 respondents who used 28 national park offices at 32 national park trail entry areas. The field research was collected in 3200 surveys, divided between pre- and post-implementation of the Environmental Improvement Project. The study variables consisted of socio-demographics, visitors' perceptions on the environmental improvement of trail entries, effects of the environmental improvement, and visitor satisfaction. Several important results were found. First, the environment of trail entries has a significant impact on the formation of images and user satisfaction of national parks. Second, the influence of the trail entry improvement showed that 71.8% of visitors rated the trail entry as environmentally friendly after the Environmental Improvement Project, compared to 48.5% of visitors rated the trail entry as environmentally friendly before the Environmental Improvement Project. The findings indicated that a top priority of environmental improvement of the trail entries needs to be the installation of convenience facilities such as rest areas, restrooms, and direction boards (pre: 34.5%, post: 32.6%). Third, functionality and the other nine variables were shown to enhance the effect of the environmental improvement of the trail entries at the 1% statistical significance level. Finally, results indicated that the overall satisfaction of the visitors with the park was significantly higher after the environmental improvement (t-value=25.741, p=.000), showing the satisfaction score was higher after the environmental improvement (pre: 3.51, post: 4.12), with a statistically significant difference at the 1 % level. This study helps to understand trail entries, which have influenced the image of the national park and satisfaction. These findings can be utilized to manage and design a national park as a public space.

Hunter value ($L^*$, $a^*$, $b^*$) is a rapid and convenience method for compare with different skin color, but not suitable to compare quality with various grape cultivars. Color Index for Red Grapes (CIRG) is one of a simply convert method for grape skin color as numeric data, and many previously result showed that high correlation between CIRG index and various quality factors of grape. In this experiment, we measured CIRG index, total soluble solids (TSS), titratable acidity (TA), and total anthocyanin content on the grapes (Campbell Early, Heukbosuk, Kyoho) from the varaison to harvest. As a result, CIRG index and anthocyanin contents have an exponential correlation; r-square is each 0.8595 in the 'Campbell Early' and 0.8500 in 'Heukbosuk'. And TSS and CIRG index have a positive r-square, at the Campbell Early is 0.7758 and Heukbosuk is 0.7253. Also TA and CIRG index have a positive r-square, at the Campbell Early is 0.7279 and Heukbosuk is 0.6630. These results were shown that CIRG index is a reliable indicator for a none-destructive evaluation of the grape quality.

Estimation of liver size is essential in the diagnosis of liver disease, Many approaches have been attempted in evaluation of liver size such as the measurement of length, area and volume. Among these, area and volume measurements are accurate but complicated, so we commonly use formerly introduced various linear measurements, but in scintigraphy one must calculate the actual liver size using rate of reduction, which is time consuming. Because of these reasons, we carried out present study to represent liver size by means of a simple liver measurement like we express the cardiac size by cardiothoracic ratio. Our cases consisted of 100 clinically normal subjects as the normal group and 50 patients suffering from liver disease and diagnosed to have hepatomegaly on abdominal palpation and scintigram at Dept, of Radiology of St. Mary's Hospital, Catholic Medical College during the period of 8 months from Jan. 1980. We measured the liver size using 4 linear diameters(Fig. 1). And as the reference measurement, the distance from the right margin of the liver to the left margin of the spleen was measured. We called this "abdominal transverse diameter(ATD)". The results were as follows; 1) The smallest value was recorded in the midline vertical diameter (MVD). It was $4.2{\pm}0.4cm$ in normal group and $5.0{\pm}0.6cm$ in the hepatomegaly group. 2) The diameter using other methods ranged from 5.6 to 7.2 cm in the normal group and from 6.3 to 7.5cm in the hepatomegaly group. 3) There was significant difference in the ratio of each diameter to ATD between the normal and hepatomegaly group (<0.01). We called this "hepato-abdominal ratio". 4) The "hepato-abdominal ratio" using MVD is $0.43{\pm}0.06$ in the normal group and $0.53{\pm}0.07$ in the hepatomegaly group. The "hepato-abdominal ratio" of MVD was most significantly different between normal and hepatomegaly group. 5) The tolerance limits(99%) of "hepato-abdominal ratio" using MVD is from 0.41 to 0.45 in the normal group and from 0.51 to 0.55 in the hepatomegaly group. Therefore, by reasons of error during measurement and convenience of memory, it was warranted to suggest hepatomegaly when "hepato-abdominal ratio" using MVD is more than 0.5 in the interpretation of hepatic scintigram.

This study was conducted to evaluate two sample digestion procedures and instrumental determination parameters for analysis of lead in bone. Amputated human legs were treated by acid digestion or microwave dissolution prior to spectrometric analysis. Inductively coupled plasma mass spectrometry (ICP-MS) and graphite furnace atomic absorption spectrometry (GF-AAS) were used for determining bone lead levels. Recovery efficiencies using standard reference material from acid digestion measured by ICP-MS were in good agreement with those of the certified value, but in cases of acid digestion by GF-AAS and microwave digestion by both two methods, recovery underestimated and overestimated, respectively. For the bone samples, the lead concentrations obtained by ICP-MS after acid digestionwere in good agreement with those by GF-AAS (correlation coefficient = 0.983), but GF-AAS gave systematically higher values than ICP-MS. While a good agreement between two analytical methods after microwave digestion was also obtained (correlation coefficient = 0.950), bone lead concentrations from microwave were relatively higher than those from acid digestion. In conclusion, the use of the simple nitric acid digestion procedure at an ambient temperature coupled to ICP-MS seems to be efficient for the determination of lead in bone in consideration for both the convenience and validity.

Purpose - Satisfaction with service is evaluated according to customers' subjective judgment. The expected value of customer service and its evaluations depend on the customers' position. The customer recognizes two different forms of service levels. One is satisfaction and the other is dissatisfaction. Customers who are satisfied want to receive the service in future. However, those dissatisfied try to change the service. The service provider tries to improve the service. There are two different service cycles. One is the successful cycle and the other is the failure cycle. This study aimed to empirically determine the effects of the justice and authenticity of service recovery on customer behavioral intention through an integrated approach to cognitive justice and psychological authenticity. Research design, data, and methodology - Based on a literature review, justice of service recovery was categorized into three types: distributive, procedural, and interactive. Then, authenticity was added to obtain four independent variables, along with recovery satisfaction as a parameter. Behavioral intention, as an outcome variable, was divided into the repurchase intention and positive word-of-mouth. The model and hypotheses were created and measurement items were developed. A questionnaire survey of items concerning the service recovery experience at family restaurants was conducted on college students and residents in Gwangju from September 30 to October 31, 2013. A total of 400 copies of the questionnaire were sent out and 385 were returned. Respondents answered questions about the importance of, and satisfaction with service recovery on a 5-point Likert scale. Excluding 174 copies without service failure experiences and 7 inappropriate copies, 204 copies were analyzed using SPSS 21.0 for Windows and AMOS 20.0 to determine the reliability and validity of measurements. The hypotheses were tested through a goodness-of-fit analysis. Results - First, distributive justice positively affected recovery satisfaction. Second, procedural and interactive justice had no impact. Third, authenticity positively affected recovery satisfaction. Fourth, distributive justice had relatively stronger effects on recovery satisfaction than authenticity. Fifth, recovery satisfaction significantly affected repurchase intention and positive word-of-mouth and it proved effective in mediation. Finally, additional analysis was performed for descriptive statistics of the principal variables by various demographic characteristics and significant differences were found in gender, occupation, and so on. Conclusions - This study has academic significance as the fairness and authenticity of service recovery were investigated to reveal the effects on behavior. The findings could be applied to a wide range of service recovery strategies. However, there are some limitations. First, data was collected only from the residents of Gwangju and most respondents were aged 20-30. Future studies should target a wide range of areas and age groups. Second, because the questionnaire used in this study targets only convenience family restaurants, the results of this study cannot be generalized to all services companies. Future research should be done on a wide range of industries such as hotels, airlines, and hospitals, and perform a comparison between sectors.

Purpose - PB (Private Brand) refers to the product for which the distribution company plans the production independently, consigns the production to the manufacturer, or attaches the self-developed trademark and sells it. To reinforce competitiveness in such a market environment, diverse products development, systematic management activities, and marketing efforts to analyze and understand the consumers' behavior regarding PB products are emphasized. Therefore, this study aims to investigate the relationships among PB product attributes, consumption emotion, brand attitude, and brand loyalty in general supermarkets. First, PB product attributes were defined using the five categories of perceived price, store image, familiarity, perceived service, and perceived quality, based on preceding studies. This study examined the influence of PB product attributes on consumption. Further, this study examined the relation among consumption emotion, brand attitude, and brand loyalty. This study provides more detailed and concentrated strategic implications. Research design, data, and methodology - In this study, the research model was designed to examine the relation among PB product attributes, consumption emotion, brand attitude, and brand loyalty. For the data collection method, the questionnaire survey comprised multiple items for each component and the direct interview method was employed. To collect data, the questionnaire survey was conducted for customers who personally visited the general supermarket after verifying the PB product purchase experience. The questionnaire survey was performed for one month, May 2014. A total of 300 questionnaires were distributed and 240 questionnaires were used for the analysis, excluding the unanswered and insincere questionnaires. The data were analyzed using SPSS ver. 20.0. Results - First, PB product attributes had a significantly positive effect on consumption emotion. The PB product attributes perceived by the customer at the point of service contact are important to form the positive consumption emotion. Second, consumption emotion had a significantly positive effect on brand attitude. Third, the consumption emotion had a significantly positive effect on brand loyalty. Such consumption emotion is an important factor in causing the positive evaluation on the brand attitude perceived by the customer. Fourth, brand attitude had a significantly positive effect on brand loyalty. The consumption emotion was positively represented to invoke the relational continuance behavior. The relational continuance behavior accompanies the repetition of purchase, word of mouth, and recommendation activities, and influences trust regarding the brand, for which the customer maintains the transaction continuously. Conclusions - The PB product attributes perceived by the customer at the point of service contact are important factors to form the positive consumption emotion. Based on this result, the discount store service provider would prepare the measures that can make the customer recognize the positive value, and make more detailed efforts. Consumption emotion is an important factor to cause the positive evaluation on the brand attitude perceived by the customer. Based on this result, the general supermarket must make efforts to provide fun or convenience in the purchase process for consumers.
