Recently, the Korean Railroad have been operating separately by Korea Rail Network and the Korail since 2005. In addition, because of the lack of government's social overhead capital, New railway projects have been built and operated by private investors which don't have railway operating experience. Therefore, systems engineering management is needed from the initial planning stage to the construction and the opening. In this paper, structural features were considered according to the separation of Daegok-Sosa-Wonsi Private Finance Initiative (Daegok-Sosa, Sosa-wonsi) and the operating agency's unification(Daegok - Sosa business operations). And based on the domestic system engineering applications, System-Engineering Implementation was studied.

Engineering changes are indispensable engineering and management activities for manufactures to develop competitive products and to maintain consistency of its product data. Analysis of engineering changes provides a core functionality to support decision makings for engineering change management. This study aims to develop a method for analysis of engineering changes based on On-Line Analytical Processing (OLAP), a proven database analysis technology that has been applied to various business areas. This approach automates data processing for engineering change analysis from product databases that follow an international standard for product data management (PDM), and enables analysts to analyze various aspects of engineering changes with its OLAP operations. The study consists of modeling a standard PDM database and a multidimensional data model for engineering change analysis, implementing the standard and multidimensional models with PDM and data cube systems and applying the implemented data cube to core functions of engineering change management, the evaluation and propagation of engineering changes.

Since the early 1980's there has been explosive growth in the trading of financial derivatives, particularly in the OTC(over-the-counter) derivatives market. While the market has exploded in term; of growth, much of this activity is still conducted over the phone or fax. Currently, over 2,083 trillion Korean Wons are spent during 2003 by the OTC derivatives industry. XML provides an excellent framework for representing these highly structured products. FpML is the emerging XML-based tool for enabling e-Business in the OTC derivatives market. This paper discusses the application of FpML in building electronic platform designed to promote efficiencies for this market and propose the framework for STP(Straight Transaction Processing) system for OTC derivatives processing which can solve the problems with manual operations.

Recently, activation of related construction projects due to the large traditional gas resource development of frozen soil region of Russia are expected. It is necessary to provide a plan that can be utilized and collectively managed the occurrence data in the engineering & construction stage for continued contracts of the pipe construction. Therefore, this research is aimed to provide a management plan of occurrence data for efficient management in engineering & construction stage of pipeline business in frozen soil region. The data of the engineering & construction(related pipe construction projects) can be accumulated each version and multiply managed. Furthermore, I will be expected to be the foundation of the systematic management of the classifying based on metadata and the optimizing operations using big data method.

Although there has been an upcoming recognition in the repairing reinforcement and remodeling of currently existing buildings with a regard to economic and resource saving effects of buildings roughly exposed to the open air for a long-term period, followed by a number of problems with the construction business operations that support economy-oriented projects within the limits of their short-term period durability, it is true that reasonable decisions of concrete performance are insufficient owing to the lack of proper history management for those existing buildings. This research attempted to comparatively analyze the compression strength together with investigation of carbonization depth and alkali concentration according to the passage of years on the subjects of aged buildings, and to provide basic data for remodeling and/or reconstruction of future construction structures by indirectly estimating durability lifetime expectancy according to carbonization phenomenon.

Electronic commerce is the use of computers and telecommunications in the routine business transactions that most affect the basics of an organization's operations: everyday relationships with suppliers, customers, banks, insurers, distributors, and other trading partners. There are problems about the governing laws and the jurisdiction in the electronic commerce contract. This paper is to investigate the governing laws and the jurisdiction in the electronic commerce contract.

Quality is recognized as one of the key components of business strategies. In this respect, this study aims to investigate quality factors that influence customer satisfaction and loyalty in Korean Tofu restaurants and promote the quality improvement in their service operations. The experimental data were collected from the questionnaire answered by 130 customers in Seoul and Kyonggi area. They were statistically analyzed using SPSS Win.12.0. For statistical analysis, frequency, factor analysis, reliability analysis, and regression analyses were conducted. The results of the analyses show that two dimensions such as "empathy" and "IT use" influence the satisfaction of customers. "Empathy", "tangibles", "well-being food", and "customer satisfaction" were identified as critical factors influencing the loyalty of customers.

Supply Chain Management is the process of planning, implementing and controlling the operations of the supply chain to satisfy customer requirements as efficiently as possible. It spans all movements and storage of raw materials, work-in-process inventory, and finished goods from point-of-origin to point-of-consumption. Korean Standards Association claims the Supply Chain Quality Management(SCQM) as a win-win model of organizations among the supply chains for the best product/service quality to final customers. The SCQM is focused on quality of product/service and will do much for improving manufacturing performance between customer and suppliers. Consulting-teams make every effort to design suitable solution for constructing solutions and improving the performance. This study is to analyze the performance of SCQM consulting, from July of 2007 to June of 2008, and would provide some guidelines to design the optimal consulting models and develop guidebooks.

The ubiquitous computing environment is widely expanded in almost all industries such as transportation. physical distribution, manufacturing, communication, tourist industry, financial business, and so on. But the construction industry is not well applied yet. Thus this study investigate the ubiquitous computing environment and propose a way for applying this technology to the construction industry. To achieve this aim, this study consider about a instrumentation management of retaining wall system in earthmoving operations, and suggest the ubiquitous system configuration to measure the variance of retaining wall. Through this system, the efficiency of the instrumentation management of retaining wall will be improved.

In the Reporting Cell Location Management (RCLM) system, a subset of cells in the network is designated as the reporting cells. Each mobile terminal performs location update only when it enters one of these reporting cells. When a call arrives, the paging is confined to the reporting cell the user last reported and the neighboring bounded non-reporting cells. Frequent location update may result in degradation of quality of service due to interference. Miss on the location of a mobile terminal will necessitate a search operation on the network when a call comes in. We must decide the number of reporting cells and which cell should be reporting cell to balance the registration (location update) and search (paging) operations to minimize the cost of RCLM system. This paper proposes a ranking ant colony system (RACS) for optimization of RCLM system.
