In this paper, a method to generate the extended model automatically on the critical elements in enterprise system based real time distributed architecture as well as the platform specific model(PSM) for Microsoft(MS) .NET platform is proposed. The key ideas of this method are real time distributed architecture should performed with satisfying strict constraints on life cycle of object and response time such as synchronization, transaction and so on, and .NET platform is able to implement functionalities including before mentioned by only specifying Attribute Code and maximizing advantages of MDA. In order to realize the ideas, functionalities which should be considered enterprise system development are specified and these are to be defined in Meta Model and extended UML profile. In addition, after definition of UML profile for .NET specification, by developing and applying these into plug-in of open source MDA tool, and extended models are generated automatically through this tool. Accordingly, by using proposed specification technology, the profile and tools easily and quickly reusable extended model can be generated even though low level of detailed information for functionalities which is considered in .NET platform and real time distributed architecture. In addition, because proposed profile is MOF which is basis of standard extended and applied, UML and MDA tools which observed MOF is reusable.

In this study, the characteristics of the experimentally produced high N-high Cr bearing stainless steels are discussed as a part of applications of materials for FGD (Fuel Gas Desulfurization) system of thermal power plants or for power plants using seawater as coolant. Corrosion resistance of developed alloys is especially investigated in detail. Corrosion characteristics of vacuum melted cast are shown to be superior to that of air melted one. From the viewpoint of CPT, It is estimated that the differences of corrosion resistance are $21.8^{\circ}C{\sim}24.6^{\circ}C$ at PRE 40 and $8^{\circ}C{\sim}12.4^{\circ}C$ at PRE 50, and the gaps becomes bigger as the PRE values are lower. In the evaluation of corrosion resistance in alloy A2501, Z3101, and A3301 according to Cr concentration, alloy A3301 shows a deviation from the general tendency in chloride solutions. It has relatively high PRE value as 48.6, but it has relatively poor pitting resistance. It is, however, difficult to observe a specific phase except ferrite in microstructure analysis and neither detects special phase such as sigma phase.

Although human beings have been able to lead the affluent life owing to industrialization and development of science and technology, as the result of this, the nature has be destroyed, energy consumption has been accelerated, urban area has got wide and the nature has got narrow. In the face of such critical situations, concerns have been aroused to environment. In order to minimize the environment destruction and accompany the aesthetic, efficient and advantage methods, environmental marketing has been introduced to indoor. Environmental marketing is the marketing that minimizes the reverse function so as to obtain the satisfactory result, and it is still in the stage of fundamental investigation. stage. As the concept and type of environmental marketing have not been established yet for interior design, environmental marketing currently applied to indoor space is classified Into three types in this study. Through the four types of environmental marketing, which are the introduction of natural elements to indoor space, the use of eco-friendly materials and the use of sustainable materials, renovation it is intend to derive the environmental marketing strategy and present the sequence of strategy establishment and desirable direction in environmental marketing.

Purpose: This study identifies the critical elements of relationship management required to be studied in distribution sciences to create a relational bond of watch manufacturers with their retailers in India. The offline watch retail market is undergoing a rapid transformation due to technology intervention in the product portfolio and the advent of online retailing. The study identifies the interrelationships amongst the constructs of interdependence, trust, affective commitment, and information exchange to form long-lasting relational bonds in the watch industry. Research design, data and methodology: We used a path analysis to investigate the relationship between interdependence, trust, affective commitment, and information exchange. Data has been collected from 143 watch retailers using judgmental sampling method. Results: The data analysis suggested the establishment of measurement and structural model. The absolute and relative goodness of fit models in the causal analysis are 0.628 and 0.959 suggesting a sufficient fit index. Based on the analysis of direct and indirect effects, the results indicate that trust fully mediates the effect of interdependence and information exchange of retailers with the manufacturer. Conclusions: Trust plays an important role in driving commitment and information exchange between watch manufacturers and retailers. Interdependence in the manufacturer-channel relationships would lead to affective commitment only when trust exists in the relationship. [AMAWATE, Vibhas.] in Web of Science and Scopus).

This study investigates the social network among authors to improve the quality of Panel researches. Korea Health Panel (KHP), implemented by the collaborative work between KIHASA (Korea Institute for Health and Social Affairs) and NHIC (National Health Insurance Service) since 2008, provides a critical infrastructure for policy making and management for insurance system and healthcare service. Using bibliographic data extracted from academic databases, eighty articles were extracted in domestic and international journals from 2008 to 2014, April. Data were analyzed by NetMiner 4.0, social network analysis software, to identify the extent to which authors are involved in healthcare use research and the patterns of collaboration between them. Analysis reveals that most authors publish a very small number of articles and collaborate within tightly knit circles. Centrality measures confirm these findings by revealing that only a small percentage of the authors are structurally dominant, and influence the flow of communication among others. It leads to the discovery of dependencies between the elements of the co-author network such as affiliates in health panel communities. Based on these findings, we recommend that Korea Health Panel could benefit from cultivating a wider base of influential authors and promoting broader collaborations.

Around the world, there is an increasing interest in Digital Twin cities. Although geospatial data is critical for building a digital twin city, currently-established spatial data cannot be used directly for its implementation. Integration of geospatial data is vital in order to construct and simulate the virtual space. Existing studies for data integration have focused on data transformation. The conversion method is fundamental and convenient, but the information loss during this process remains a limitation. With this, standardization of the data model is an approach to solve the integration problem while hurdling conversion limitations. However, the standardization within indoor space data models is still insufficient compared to 3D building and city models. Therefore, in this study, we present a comparative analysis of data models commonly used in indoor space modeling as a basis for establishing a generic indoor space feature model. By comparing five models of IFC (Industry Foundation Classes), CityGML (City Geographic Markup Language), AIIM (ArcGIS Indoors Information Model), IMDF (Indoor Mapping Data Format), and OmniClass, we identify essential elements for modeling indoor space and the feature classes commonly included in the models. The proposed generic model can serve as a basis for developing further indoor feature models through specifying minimum required structure and feature classes.

Whereas the necessity for recycling and reuse is being emphasized owing to the depletion of resources and waste disposal problems caused by the continuous development of the industry, the importance of remanufacturing has been highlighted recently. Re-manufacturing involves a series of processes in which failed disposal or aging goods are recovered to a state similar to that of a new product. In this regard, machine tools, which are large structures, can achieve the effect of remanufacturing. Among the various elements constituting the machine tool, the main spindle portion that affects the processing precision is critical. Therefore, this study is conducted to derive improvement measures for the main axis of an old Miller planner via reverse engineering and central composite design, which is one of the core processes of remanufacturing.

In Korea, small and medium sized domestic enterprises(SMEs) play an pivotal role in the national economy, accounting for 99.9% of all enterprises, 87.5% of total employment, and 47.6% of production. and SMEs was driving a real force of the development of national economy in many respects such as job creation, innovation, balanced regional development, industrial diversity. The government has strengthened a variety of policy support to support SMEs. However, due to the mismatch between the difficulties of SMEs and benefits of government's policy, the policy implementation has not come out effectively. In order to effectively support SMEs, government must be a priority to know about the factors that experiencing difficulties in the technology commercialization process. The purpose of this study is thus to identify the major evaluation criteria through 3 level AHP analysis. First, 12 Critical elements are extracted from previous studies and professional interview and these elements are tied into 3 factors; technological factor, inner-organizational factor and Outer-organizational factor. The results of AHP analysis show that inner-organizational factor is more important and 'Market environment' in the inner-organizational factor is the most important element. The results of this research will be useful for public R&D institutions policy makers when establishing technology commercialization support policies and strategic planning of small and medium sized domestic enterprises.

The Korean government's support towards the establishment of leading research hubs at universities began with the initiation of the Science/ Engineering Research Center in 1990. Such efforts to provide support to research organizations have continued for some twenty years in various forms, which implies that building research hubs was critical in acquiring global leadership in research. However, the effect of such research hub nurturing policies has never been properly evaluated, apart from an assessment of their validity. Therefore, this paper analyzes how major programs to form research groups by providing assistance to joint research by researchers at universities are operated, and the characteristics of such programs through comparative analysis with other programs. There are two major focal points in the analysis: the first is the evaluation of the level of differentiation between Research Organization Support Programs (ROP) and other R&D Programs from an efficiency perspective, and the second is an examination of the extent of systematization of research organizations that exist at universities and impact of Research Organization Support Programs on the activities of participating professors from an effectiveness perspective. The result showed that the ROP were no longer only relevant for the formation and maintenance of research groups. Other R&D Programs are growing increasingly larger in scale and conducted over longer periods of time. Thus, the ROP can no longer be differentiated from other programs in research period and size of funding. An analysis on the effect of ROP demonstrated that all activities by participating professors in organizations that were the beneficiaries of group research assistance were more active compared to their counterparts in organizations that received other research support, but there was little difference in the elements of systematization. This implies that the joint research conducted at universities is not systematized and that it is still research based on individual themes but conducted jointly. In addition, it also means that the ROP is failing to effectively lead the systematization of research. In other words, today, university research organizations are not operated as independent, long-term bodies, but are more relevant as a combination of research units of individual professors.
