In spite of numerous advantages in railroads such as mass transportation, high reliability, and environmental soundness etc., the value of railroad construction is relatively underestimated compared to road. This is because the current method of evaluation focuses mainly on economic effect. In this study, considering recent research results, the environmental value of railroad construction was assessed by calculating the effect of reduction of emissions and water contamination. With these two benefits, the environmental effect produced by railroads and road construction was calculated and compared to each other using EMME/3. As a result, the senario 4 which considers 'Hot/Cold start' condition and water contamination had highest benefits. Furthermore, the environmental effect produced by railroad is 55~101% higher than road construction. If the suggested method is used in the current appraisal system, the environment-friendly mode like railway would be highly valued, much more than before.

From the "Recommendation on the Safeguarding of the Beauty and Character Landscapes and Sites"(1962) to the "ICOMOS-IFLA Document on Historic Urban Public Parks"(2017), 'the spatial safeguarding Concept of Cultural Heritage' in International Norms has manifested in various types. In this article, 24 types of International Norms that reflect 'the concept of Spatial Safeguarding in Cultural Heritage' and Korea legal system such as 'Historical and Cultural Environment' were analyzed in the following two aspects. The first aspect is 'Object Type to safeguard' and analyzed in four types such as 'Groups of buildings(A type)', 'Surrounding, Environment, Setting(B type)', 'Cultural landscape(C type)', 'Historic area and Historic towns(D type)'. The second aspect is 'Safeguarding value(analysis elements)' and analyzed in the following tree elements ; 'Landscape value' such as skyline, 'Intangible value' such as the functions of cultural customs, and 'Ecological value' that should preserve life itself. As a result of the study, 'the concept of Spatial Safeguarding in Cultural Heritage' including C and D type and three value which are trends of International Norms are reflected in Korea legal system, and concrete safeguarding methodology is also implemented systematically in case of ecological value. However, intangible values are not specific to the methodology in both International norms and Korea legal systems, and should be developed in the future.

The main purpose of this study is to find out how perceived risk elements influence to customer's perceived value and repurchase intention in the electronic commerce environment. To achieve the goal, we set 6 sub-dimension - privacy risk, social risk, time lose risk, economic risk, psychological risk, and performance risk - based on comprehensive consideration of related studies, and established a research model included 2 factors such as perceived value and repurchase intention to measure performance in internet shopping malls. From 174 customers of the electronic commerce shopping malls survey data have been collected and analyzed based on the covariance structural model method. Firstly, four perceived risk characteristics of privacy risk, economic risk, psychological risk, and performance risk are significant effect on perceived value. Secondly, perceived value is very significantly related to repurchase intention in electronic commerce shopping malls. Consequently, we discussed the strategies to create perceived value and repurchase intention in electronic commerce environment. Also, we suggested the implications and further research directions.

In today's rapidly changing business environment, "core value" has been emerging for companies to survive as "going concern" and respond to the conditions of the market environment and prosper together as the uncertainty about the future grows. LG Way states the contents to achieve "Number 1 LG" which is the vision of LG through achieving "Do it the right way and concentrate to what we can do best" which is the LG behavior methods through "value creation for customers" and "management of human dignity" which are LG corporate philosophy. It provides directions of various management activities and institutional development and also provides the foundation of core competencies. the core value provides the future directions in an uncertain business environment and plays an important role in maintaining a continuous going concern through members of the organization and the growth of the organization. Therefore, in order for the core values to be shared among the members of the company, the chief executive officer of the company should present a clearer core value. By conducting continuous monitoring if the members have properly settled, they should be able to conduct going concern by the core value acting as the source of competitive advantage of the company.

This study was undertaken to understand the interrelationships among customer's perceptions of service encounters, customer value, and behavioral intent in a family restaurant. Based on 331 samples obtained from empirical research, we reviewed the reliability and fitness of a research model and verified three hypotheses using a structural equation model. The results showed that physical environment (${\beta}$ = .418) and a customer interaction with the service provider (${\beta}$ = .265) had a significant effect on the customer's hedonic value. Additionally, physical environment (${\beta}$ = .126) and customer interaction with service providers (${\beta}$ = .264) had a significant effect on customer utilitarian value. Customer's hedonic (${\beta}$ = .538) and utilitarian value (${\beta}$ = .382) triggered by service encounters had a significant effect on their behavioral intent. Limitations and future research directions are discussed.

This research examined how the experience factors and environmental factors of experience store impact the perceived value of the brand and whether the perceived value enhance revisit intention. We collected 258 survey responses and formed structural equation modeling. The results indicated that education experience and esthetics experience had positive impacts on emotional value, while entertainment experience had a positive impact on functional value. Among environment factors, lighting, employee service and layout of the store had positive impacts on functional value, while lighting and employee service had positive impacts on emotional value. Both of the functional value and emotional value enhanced the revisit intention of customers. The results of this study are expected to provide useful information about consumers to the companies managing offline experience stores.

This paper describes the modeling of work environment for the extraction of abstract operation rules for cooperative work with multiple agent. We propose the modeling method using a potential field. In the method, it is applied to a box pushing problem, which is to move a box from a start to a goal b multiple agent. The agents follow the potential value when they move and work in the work environment. The work environment is represented as the grid space. The potential field is generated by Genetic Algorithm(GA) for each agent. GA explores the positions of a potential peak value in the grid space, and then the potential value stretching in the grid space is spread by a potential diffusion function in each grid. However it is difficult to explore suitable setting using hand coding of the position of peak potential value. Thus, we use an evlolutionary computation way because it is possible to explore the large search space. So we make experiments the environment modeling using the proposed method and verify the performance of the exploration by GA. And we classify some types from acquired the environment model and extract the abstract operation rule, As results, we find out some types of the environment models and operation rules by the observation, and the performance of GA exploration is almost same as the hand coding set because these are nearly same performance on the evaluation of the consumption of agent's energy and the work step from point to the goal point.

In this study, it is an object to develop a regression model for the estimation of TOC (total organic carbon) concentration using investigated data for three years from 2010 to 2012 in the Gam Stream unit watershed, and applied in 2009 to verify the applicability of the regression model. TOC and $COD_{Mn}$ (chemical oxygen demand) were appeared to be derived the highest correlation. TOC was significantly correlated with 5 variables including BOD (biological oxygen demand), discharge, SS (suspended solids), Chl-a (chlorophyll a) and TP (total phosphorus) of p<0.01. As a result of PCA (principal component analysis) and FA (factor analysis), COD, TOC, SS, discharge, BOD and TP have been classified as a first factor. TOCe concentration was estimated using the model developed as an independent variable $BOD_5$ and $COD_{Mn}$. R squared value between TOC and measurement TOC is 0.745 and 0.822, respectively. The independent variable were added step by step while removing lower importance variable. Based on the developed optimal model, R squared value between measurement value and estimation value for TOC was 0.852. It was found that multiple independent variables might be a better the estimation of TOC concentration using the regression model equation(in a given sites).
