This paper suggests blending time adjusting method of braking command characteristics management and Set value test for optimizing of braking deceleration to enhance the precise position stopping. This method minimizes pneumatic-braking degree deviation by characteristics management, and secures braking stability at braking. By Set value test method, braking blending characteristics are analyzed accurately. And by optimal timing tuning at braking blending, It enhanced the precise position stopping with stabilization of deceleration To demonstrate the usefulness of these suggestion, I modeled for Deajeon Line #1. And through comparison with case of related companies, the proposed method which this paper suggested is proved to be superior to others.

Color-code imaging should be one of the best display tools for the quick perception of both damage area and its intensity, In this study we proposed the standard color code corresponding to maximum observed acceleration value. Since the acceleration value changes with frequency contents, we suggested to limit the frequency band less than 10Hz. The background considerations of this limitation, magnitude vs. dominant frequency, natural characteristics of artificial noises and the relationship between velocity and acceleration, were reviewed in detail. The standard of color code was assigned from 0.001%g to 20%g based on the possible earthquakes at Korean peninsula and the color imaging given by RGB value was shown to be very consistent, irrespective of hardware configuration.

To implement total quality management(TQM), firms and institutions have strategically used quality awards models. In this paper we analyzed the national quality awards of G-20 members such as United States, Europe, Japan, Canada, Australia and Korea. There are three main points to analysis; First, "which type of model is good for Korea?", even though Korea already has adopted MBNQA model. Second, "Are the core values really different from each models?". And third, "Is there any difference in the criteria structure and value points system?" This study aims to design a National Quality Award which is good for the Korean companies and organizations. After analyzing the current quality awards models, we propose some suggestion about core value setting Korean-specific criteria development and value points system change.

This research applies Blattberg's CE (customer equity) model to B2B business context. Through the model we estimate customer lifetime value of a Korean semiconductor manufacturer. The results show that Blattberg model has limiting applicability to B2B business context. To overcome the limits, several suggestions were made. The main suggestion was predicting maintenance costs for different customers groups and including decision variables regarding marketing costs that would help building a differentiated CE model for the B2B business context.

Shear strength of the rock joint is dependent on the roughness and the compressive strength of the joint surface, normal stress and etc. Roughness of the joint profile is described by JRC suggested by Barton and Choubey (1977). Choice of the JRC value is subjective. A number of studies have been carried out to quantify the JRC. Predicted shear strengths by Barton's Equation using the new quantification method of JRC suggested by Chun and Kim (2001) were compared results of shear tests and new criteria of shear strength which have a better accuracy to predict shear strength was suggested.

This study examines the differences of enacting models and influential causes of benefit-sharing practices between Korean automobile networks and the Japanese networks. The case study method is chosen for this research because only small numbers of supply networks adopt benefit-sharing practices. I employ semi-structured interviews with managers from four automobile manufacturers and eight of their suppliers in South Korea and Japan. I find that Japanese automobile networks have adopted a higher level of trust-demanding, with a higher level of value-creating models such as supplier development, joint-new-product development. Whereas, the Korean networks have adopted the lower trust demanding, also less profitable models such as supplier's suggestion and buyer's suggestion. In terms of work-related cultural values, I find that Japanese networks emphasized collectivism. Both buyers and suppliers in the Japanese networks are supposed to have common causes. In contrast, Korean networks emphasized individualism. Both buyers and suppliers of Korea generally do not identify that they are common group members with a common cause. I also find that a slight differences of the enacting models and the causes between foreign-owned networks and domestic-owned networks within each country. Foreign-owned networks have adopted lower trust demanding, also less profitable models. The findings demonstrate that the cultural values have a decisive influence on the adoption of benefit sharing models for the networks in Japan, and South Korea.

Price, one of the marketing 4p's, is a key decision variable affecting market share and the profitability of individual products. For consumers, since price is almost always known to and can be compared, it is one of the most important criteria when they make a purchase decision making. With the consumers' increasing consciousness for price due to economic recession, and the saturation of domestic apparel market, it is expected that the effect of price on consumers' decision making would be greater than ever. This study, the first in two part series, focuses on testing the validity of dimensions of clothing price using Lichtenstein et. at. (1993)'s suggestion. In addition, the effect of demographic variables on the perception of each price dimension was investigated. The subjects were 264 college students living in Seoul, Korea. The data were collected by self -administered questionnaires and analyzed by t-test, ANOVA, regression analysis and Lisrel confirmatory factor analysis. The result supported Lichtenstein et. al. (1993)'s suggestion. That is, consumers' perception of clothing price is not mini-dimensional, but has six dimensions: sale proneness, price mavenism, value consciousness, price consciousness, price -quality schema and prestige sensitivity. Demographic variables partially effect on the consumers' perception of each clothing price dimension. The level of monthly pocket money, however, has influence on all price dimensions. Based on these results, marketing implications for apparel manufacturers were suggested.

Purpose - This study estimated the value of the post-use of Alpine stadium in Jeongseon as a tourist attraction, which is one of the 2018 Pyeongchang Winter Olympics facilities, and identified determinant factors on the willingness to pay (WTP). Design/methodology/approach - A dichotomous-choice model of contingent valuation method (CVM) that is known for an effective tool was used to calculate the value. The questionnaire was conducted on 650 visitors to major tourist destinations in Jeongseon and 629 copies of the valid samples were analyzed. Findings - The results shows that determinate factors on the WTP are; suggestion cost, need (application of Ecotourism Program to the Restoration Process), agree(agree to Ecotourism Program in the Restoration Process) and age. Also, the WTP on the facility is 16,296 won per person. Research implications or Originality - This study estimates the value of the post-utilization of Alpine Stadium of the 2018 Pyeongchang Winter Olympics facilities, which have been experiencing conflict in recent years. For this reason, the findings of the paper will provide meaningful information for tourism development and management policies of the region.

Recently people are trying to lead their life with meaning and value, and people are oriented to value consumption as the values they pursue can be realized through consumption. Consumer demand on value consumption had an effect on Korean wedding culture and 'value consumption wedding culture' which emphasizes the value of marriage, is on the rise as a new wedding custom. Accordingly, Korean wedding market is more segmented and diversified for individual customization to create value. Especially, wedding dress evidently reflects the tendency of value consumption as it gives special meaning for brides. As a result, suggestion and development of detailed design elements of wedding dress to meet the various needs of customers are needed. Therefore, this study has the purpose of investigating the required value of wedding dress aligned with the characteristics of value consumption wedding culture through in-depth interviews and how the intrinsic value of consumers is shown up to a particular design element through investigating on the relationships between design elements. In addition, the study provides a direction for specialized and high-valued wedding dress design development by suggesting wedding dress design aligned with the new trend based on the analysis of detailed design elements that reflects the value.

Overflow queuing models are ofter analyzed by explicitly solving a large sparse singular linear systems arising from Kolmogorov balance equation. The system is often converted into an eigenvalue problem the dominant eigenvector of which is the desired null vector. In this paper we convert an overflow queuing problem the dominant eigenvector of which is the desired null vector. In this paper we convert an overflow queuing problem into an overflow queuing problem into an eigen-value problem into an eigen-value problem of size 1/2 of the original. Then we devise an orthogonal projector that enhances its convergence by removing unsanted eigen-components effectively. Numerical result with some suggestion is given at the end.
