The KNR(Korean National Railroad) is trying to set a new rail standard to back up the speed-up policy of the conventional railways. This work has passably significance since the rail standards used were introduced from Japan without the consideration on our situation. The contact analysis between wheel treads and rail heads, attended with complex calculation and the wear experiments taken long time should be accomplished for the exact investigation to establish a new rail standard. However, this paper just concentrates the structural investigation of the proposed rail standard and the dynamic analysis between trains and rail models with intent to shift the above procedure on the next step.

This study analyzed the expression of hanbok in online fashion styling games, and examined the main themes of and user reactions to hanbok fashion styling games through semantic network analysis and sentiment analysis. KrKwic, Textom, and NodeXL were used for data collection and analysis. The findings of the study are as follows: First, depending on the designer's expressive method, hanbok fashion styling games provide typical traditional hanbok, modern hanbok, and dress-like fusion hanbok, demonstrating contents with various themes for different sexes, classes, and situations. Second, as a result of analyzing the themes of hanbok-related styling game contents, it turned out that the main themes are tradition, color, historical drama, fusion hanbok, holiday, and love. Most of them produce modernized hanbok that reflect the situation and utility rather than strictly traditional ones. Third, as a result of analyzing user reviews of hanbok styling game contents, positive factors mostly turned out to be the satisfaction of the hanbok contents, with the users also showing positive intent to wear hanbok. Through this, it was found out that hanboks portrayed in game contents could potentially cause the user's positive intent to wear hanbok. Negative factors turned out to be the discordance between the intrinsic image of hanbok and the game character's image.

Public open data is a database or electronic file produced by a public agency or government. The government is opening public data through the open data portals and individual agency websites. However, it is a reality that there is a limit to search and utilize desired public data from the perspective of data users. In particular, it takes a great deal of effort and time to understand the characteristics of data sets and to combine different data sets. This study suggests the possibility of interlinking between data sets by analyzing the common relationship of item names held by public data. The data sets are collected from the open data portal, and item names included in the data sets are extracted. The extracted item names consist of formal context and formal concept through formal concept analysis. The format concept has a list of data sets and a set of item name as extent and intent, respectively, and analyzes the common items of intent end to determine the possibility of data connection. The results derived from the formal concept analysis can be effectively applied to the semantic connection of the public data, and can be applied to data standard and quality improvement for public data release.

The purposed of this research is to develop multimedia content usage analysis service platform. In the proposed platform, the content gazing behaviors of the users are monitored and profiled in real-time and a set of quantifiable metrics is provided. These metrics are used to determine the closeness of the users' behavior from the intent set by the provider. Based on the evaluation, it is possible to assess the effectiveness of the contents themselves as well. The content usage assessment is accomplished by utilizing the intention flow and the intent weight, which are embedded into the content by the content provider. Proposed methodology can be effectively applied and used in various application domains such as in education and in commercial advertisements.

The purpose of this study is to analyze the influence of the crowdedness of dining franchise liquor shops on the perceived values and revisit intention. For this purpose, 361 customers who had visited dining franchise liquor shops located in Seoul and Gyeonggi-do areas were surveyed, and data was analyzed using AMOS 23.0 and SPSS 23.0 statistics programs. The analyses yielded the following findings. First, a higher level of crowdedness in the shop turned out to lower the perceived value of users. Second, a higher level of perceived value resulted in a higher level of revisit intent. Third, the analysis on the mediating effect of the perceived value showed that, in the relationship between the human crowdedness and revisit intention, both practical and hedonic values had mediating effects. However, in the relationship between the spatial crowdedness and the intent of revisit, the practical value had a mediating effect, while hedonic value did not exhibit such an effect. This study is meaningful in that it is presented as a theoretical establishment and an empirical study on dining franchise liquor shops.

Objective: We investigated visual marbling level (VML) influence on pork loin physicochemical traits, consumer palatability responses, VML liking, purchase intent, and their relationships. Methods: For each of five slaughtering dates, at 24-h postmortem, nine paired Duroc castrated male boneless Longissimus dorsi (LD) muscles were categorized into low (LM, score 1 to 2, n = 3), medium (MM, score 3 to 4, n = 3), and high (HM, score 5 to 6, n = 3) VML. Meat physicochemical quality traits and consumer responses (n = 389) on palatability and VML liking, and purchase intent were evaluated. The experiment was in randomized complete block design. Analysis of variance, Duncan's multiple mean comparisons, and correlation coefficients were determined. Results: VML correspond to crude fat (r = 0.91, p<0.01), but both were reversely related to moisture content (r = -0.75 and -0.91, p<0.01, respectively). As VML increased, ash (p<0.05) and protein (p = 0.072) decreased, pH and $b^{\star}$ increased (p<0.05), but drip, cooking (p<0.05) and thawing (p = 0.088) losses decreased. Among treatments, muscle fiber diameter, sarcomere length, total and insoluble collagen contents, $L^{\star}$, and $a^{\star}$ did not differ (p>0.05). Compared to the others, HM had lower collagen solubility percentage (p<0.05), but similar (p>0.05) Warner-Bratzler shear force (WBSF). No differences (p>0.05) were found in juiciness, overall flavor, oiliness, and overall acceptability, but HM was more tender (p<0.05) than the others. Based on VML, consumers preferred MM to HM (p<0.05), while LM was similar to MM and HM (p>0.05). Corresponding to VML preference (r = 0.45, p<0.01), consumers (83%) would (p<0.01) definitely and probably buy MM, over LM (74%), and HM (68%), respectively. Conclusion: Increasing VML in pork LD altered its chemical composition, slightly increased pH, and improved water holding capacity, thereby improving its tenderness acceptability. Marbling might reduce chewing resistance, as lower collagen solubility in HM did not impact tenderness acceptability and WBSF. While HM was rated as most tender, consumers visually preferred and would purchase MM.

Various government-based consulting techniques are being adapted to increase competitive power and to achieve management innovation of Korean farms. These business consulting services are offered by free or paid consulting. This study focuses on what socio-economic characteristics are affecting farmers' intension of adapting consulting services, based on 169 surveyed data from Chunchungnam-do. Logit Model is used to identify the relationship between the probability of consulting intent and factors representing farm characteristics. The model was applied on each of free and paid consulting. According to the results, degree of consulting recognition, age, education, raised crop are significant factors affecting farmers' intension of adapting consulting service in the case of free consulting at 10% of significance level. In the case of paid consulting, level of farming, age, income, insufficiency of farming, and education were identified as significant factors. In terms of elasticity of each variable, most variables for free consulting service are inelastic to consulting intent, whereas age, level of farming, and education are elastic for paid consulting service. Overall results implies that more public relations are required to activate free consulting services for the farms with moderate level of farming. In the case of paid consulting, it is effective to adapt consulting services for younger farms with higher level of farming and education.

This study analyzes the initial effect of meister high school policy on labor market by DID based on the fact that most of the meister high schools that had its first graduates in 2013 were not newly established but assigned by government. We estimated employment and real hourly wages as quantitative measures and intent to remain in labor market as qualitative one. The results shows that, the meister high school policy increased the employment rate but didn't do real hourly wages and intent to remain. Therefore, meister high school policy can be assessed to be successful in short-term only in quantitative aspects. The study has its contribution as the first study of estimating the net effect of the policy.

This study aimed to analyze the impact of importance and fulfillment(satisfaction) factors of menu quality on customers' intent of revisit of Japanese restaurants, so that it could provide information helpful to build up detailed marketing strategy and present considerations for management's higher sales amount and more efficient business results as well. Importance on menu quality scored higher level than fulfillment on the whole in Japanese restaurants. Notably, in regard to attributes of menu quality, it was found that respondents put higher stress on flavor, nutrition, cleanliness and freshness than anything else. In terms of IPA analysis on Japanese cuisine menu quality, it was noteworthy that the items with high importance but low fulfillment included menu price as an attribute for menu quality, although it was not shown in menu-specific items. In the survey on the associations between fulfillment(customer satisfaction) and intent of revisit, it was found that factors of customer satisfaction included 'trimness of dishes', 'information', 'appropriateness' and 'economic affordable' Out of these factors, it was noted that both 'trimness' and 'economic affordable' had significant effects on customer satisfaction at the significance level ranging from p<0.05 to p<0.001.
