Purpose: This study investigated the importance and performance of food/nutrition labeling. The aim was to determine how important students consider food nutritional labeling, utilization of nutrition labels in daily life, and consumer satisfaction of current nutritional labeling. Methods: This study was conducted using a primary survey of students at one high school in Seoul. A total of 300 of 382 questionnaires were analyzed. Results: Regarding difference analysis of the importance-performance of food/nutrition labeling, importance showed higher scores than performance in all 10 attributes. According to the results of Importance and Performance Analysis (IPA), 'health, weight control and maintenance, proper dietary habits, and personal satisfaction' displayed both high importance and performance in the first quadrant. Importance of two factors (health and nutritional factor and effects of media and education) of the 10 attributes positively influenced overall satisfaction in the multiple regression analysis. Conclusion: To develop healthier food choices, it is necessary to educate adolescents about food/nutrition labeling and improve the food/nutrition labeling system.

This study was performed to develop menu satisfaction index in Business & Industry (B&I) food service and to survey customer's menu satisfaction using the index. The menu satisfaction index included 16 items with Likert 5 point. Cronbach's alpha to assess the internal reliability of the developed scales was 0.8917, which indicated highly reliable. Construct validity was assessed by principal components analysis and then four factors explaining 65.964% of the total variance were found. Among the 15 items of menu satisfaction, the average scores of all items were above 3.0 out of 5. As a result of analysis on menu satisfaction factors, 'propriety of food temperature' (3.52 out of 5) was the highest consideration followed by 'sufficiency of format' (3.46), 'excellence in food' (3.35) and 'well-being orientation' (3.31). It could be said that customer's perception on the menu quality was very positive. Four factors were correlated with overall menu satisfaction positively. Especially, 'excellence in food', and 'well-being orientation' and 'sufficiency of format' affected significantly on overall menu satisfaction. It concluded that customers were satisfied with portion size, temperature, price but their needs for taste and health/nutrition-related service would be increased. The menu satisfaction developed in this study should be applied to other B & I food service operation by type.

The Purpose of this study is to identify important factors in choosing liner shipping companies using the AHP. The Analytic Hierarchy Process(AHP), introduced by Satty T. L. in 1970, is a decision technique the has been applied to private and public sectors and to group decision problems. This paper will demonstrate the level of importance in 4 major factors: cost, service, transportation and promotion. In detail, the 4 major factors are divided into 14 sub-factors. In the present research, various service attributes for shipping lines were selected from previous studies and the observed data for 4 main service attributes were collected through a questionnaire survey from 26 concerned international freight forwarder experts. The conclusion of this study is as follows. First, it is found that the cost factor is the most important factor among the 4 main service attributes. It is very obvious that the cost factor directly affects the choosing the liner shipping company by international freight forwarders. Second, it is found that the second important factor in choosing the liner shipping company is the transportation factor and the third is the service factor. The promotion factor is underestimated, comparatively speaking. With the ever-increasing competition, liner shipping companies will need to study and understand the selection criteria of their clients(international freight forwarder), and apply the results to their daily and long-terms operations. In particular, liner shipping companies should establish a system to identify and sort the various selection criteria used by international freight forwarding companies.

The purpose of this study was to analyze to 1) the differences according to demographic characteristics 2) select the type-specific communities online channels of the baby boomer customers group, who ever search for restaurant information through on-line for the previous three months. The study was based on a total of 280 samples obtained from on-line networking service users in a metropolitan area from April 15 to 30, 2016. The major findings are as follows. The data were analysed using frequency, factor analysis, cluster analysis and ${\chi}^2test$. According to the results of factor analysis, on-line utilizing attributes were separated into three factors: commitment of useful information, activity of leading on-line, and habit. The based on a factor analysis, cluster analysis was adopted to segment baby boomer customers. The identified four clusters showed in using on-line: type of active utilization, habit, seeking information and passive utilization. The clusters had significant differences in gender and monthly income by demographics. All of four clusters selected blog, face book, twitter in turn through the personal on-line channels. Cluster type of active utilization and habit selected restaurant home pages, restaurant blog, restaurant face book, restaurant twitter in turn through the public on-line channels. Cluster type of seeking information and passively utilization selected restaurant home pages, restaurant blog, restaurant twitter, restaurant face book in turn through the public on-line channels. Implications and future research were also discussed.

The complicate software failure system is defined to the superposition of the points of failure from several component point process. Because the likelihood function is difficulty in computing, we consider Gibbs sampler using iteration sampling based method. For each observed failure epoch, we applied to latent variables that indicates with component of the superposition mode. For model selection, we explored the posterior Bayesian criterion and the sum of relative errors for the comparison simple pattern with superposition model. A numerical example with NHPP simulated data set applies the thinning method proposed by Lewis and Shedler[25] is given, we consider Goel-Okumoto model and Weibull model with GOS, inference of parameter is studied. Using the posterior Bayesian criterion and the sum of relative errors, as we would expect, the superposition model is best on model under diffuse priors.

Like always selecting anything in everyday lives, We must choose a travel mode to achieve its purposes driven by diverse factors such as travel distance and accessibility of public transit. Assuming that they are differentiated depending on whether a travel purpose is commuting, shopping or leasure, the study investigated their distinguished impacts on travel mode choice by using binary logit models by travel purpose and mode. Identifying that travel time has an important role in choosing a travel mode whether its purpose is any, the results show that longer travel time tends to increase the possibilities of taking public transit, transfer and rail transit rather than bus. In addition, the easy use of a car and its parking to travelers is more important in their choosing an automobile as a travel mode than other factors. In the models of identifying the probability of mode choice between bus and rail transit, we find that its choice tends to be decided by travelers depending on whether any public transit mode is more accessible to them. When comparing the results among travel purposes, we identify that the easy use of a car and parking in their destination is more important for commuting, while accessibility of public transit in their origination increases the probability of taking a transit mode.

Purpose: This study was performed to offer some more effective marketing strategies for optical shops on a basis of analyses of what lifestyles influence most on 'store selection' and 'recommendation intention' and of what properties of 'store selection' influence most on 'recommendation intention'. Methods: Questionnaire surveys were conducted from the customers who visited the optical shops in Seoul and northern Gyeonggi-do region from January 1 to June 30, 2014. It was analyzed via utilizing SPSS v.20.0 statistical package program. Results: The results in lifestyle-factors which influence on store selection were arranged in order as follows: 'stability oriented', 'goal oriented', 'cultural activity oriented'. And the results in value-factors which influence on 'recommendation intention' were arranged in order as follows: 'stability oriented', 'health oriented'. The most positive factor for 'recommendation intention' was revealed as 'dealing with customers' among several factors of 'store selection'. Conclusions: Today's marketing activities for customers should be suited for different lifestyles of customers. Customers who have 'stability oriented', 'goal oriented', and 'cultural activity oriented' lifestyles tend to select optical shops in consideration of 21 items when selecting an optical shop. Customers who have 'stability oriented', and 'health oriented' lifestyles have positive influences related to 'recommendation intention'. Also, it is likely for customers to recommend optical shops to others when the factor 'dealing with customers' meets their expectations.
