Virtuality is a product of the information age, and as it plays a larger role in the activities of individuals, groups and organizations, the issue of how human behavior varies between virtual and physical space has become one of the most important questions facing the management environment of today. The purpose of this article is to examine how virtuality shapes individuals' social relationships within and outside their work groups. We developed a conceptual framework that explores the links between virtuality and social network based on computer-mediated communication theory and social network theory. Using data from 172 individuals of 42 project teams in 5 global business consulting firms, we tested cross-level hypotheses. The results of hierarchical linear modeling (HLM) indicate that virtuality significantly influences individual's internal tie strength as well as external bridging ties. The results also show the effects of virtual process via CMC vary along with the virtual context.

This study investigates the characteristics of Mario Botta's single-family houses. Eight of his housing project which are deemed important in the historical development of housing he been selected for the purpose their elevations plans loggie and interiors are analyzed and evaluated. Through this study the followings are realized ; $\circled1$ The rationality of his interior space comes from Le Corbusier's housing projects. $\circled2 His expression of elevations has developed from Louis. I. Kahn's language and Carlo Scarpa's technique. $\circled3$ The rationality of Corbusier's houses and expressiveness of Kahn's and scarpa's projects together led to his functional solution of internal program an and the creative external images of his own. $\circled4$ The originality of this house results from his creative vision and ability to reinterpret the existing expression and principles in the light of time and space.

Corrugated structural plate is ductile structural member which has high sectional properties compared with same thickness of plate. Corrugated plate resists the external forces by the combined action of retained soils and structures. Since it is easy to transport and assemblage of in-situ, the duration and cost of construction can be reduced. Corrugated plate structures, therefore, are widely used in culverts, hydro passages and simple bridges. RC culvert with supported by unstable soil layersin railway construction project of pohang${\sim}$samchuk has been replaced by corrugated plate culvert due to the reduction of construction duration and cost, especially the performance of behavior of settlement of ground. The structural analysis, design processes, and the economic advantages of the corrugated plate culvert are studied in this paper.

It is important to manage internal and external interfaces in a system integration. As there are many of related multi-disciplinary engineers and high level complexity in big and complex project, it is difficult that carrying out interfaces management by consistent method. We study the method that represent efficiently system interfaces by matrix structure. And we suggest the way to identify system interfaces and trace interfaces between components using Interface Analysis Matrix and Interface Control Document.

To internalize climate-related external costs from agricultural production and food consumption Pigou taxes and carbon credits increase private costs for food. Voluntary GHG reduction program for carbon-neutral food can be advantageous over such policy measures since they avoid higher food prices for the poor. The pilot project of low-carbon agriculture certification system is to reduce GHG emissions from agricultural production and enhance the competitiveness of domestic agricultural products. This study examines producers', distributors', and consumers' perceptions of the low-carbon agriculture certification system and analyzes alternatives to promote the low-carbon certificated agricultural products.

This study is intended to identify the factors affecting the successful information warehouse (IW) implementation through the technology acceptance model. As the IW has played an important role with the organizations, it has become a strategic management tool. However, because the building of an IWS requires a great amound of financing and a multi-period, managers should consider identifying the variables as a predictor of IWS success. The related research areas, such as TAM , TRA, and innovation diffusion theory, and previous research associated with the EWS success factors are reviewed in this paper. Based on the hypotheses presented , the study will empirically test the relationships between six external variable-user involvement, computer self-efficacy, OLAP characteristics, problem difficulty , user training and top management support-and system utilization via user's perceptions of ease of use, unusefulness. This study semmes to be a first attempt in this research area, and its results will provide general guidclines for IWS project managers to enhancement the like hood of system succes.

The purpose of this study is to investigate the business performance determinants of private consulting firms supporting bottom-up local development projects in rural areas. Under the shortage of well-trained rural development professionals, Private consulting firms support rural development projects driven by the residents. Considering the important role for consulting firms to play in the success in rural development projects, it becomes necessary to review the circumstances of consulting market on rural development projects. This study targeted 80 companies that are listed in the book rural development consulting firms. Analysis showed that factors influencing the business performance are not professional competencies but other external factors. The implications based on the above results need to be considered for policy-making to ensure that consulting company selection must be guaranteed of the consulting firms'capability by detailed fields of consulting firms' capability, and the training system for rural development experts must be formed.

The R&D of Geospatial Information Infrastructure, which is the one of the KLSG(Korean Land Spatialization Group) mian projects, is core project for promotion of digital korean land. It has been conducted during 4 years, and it will be tested and assessed via TestBed in the 5th & 6th years. The application of Testbed for R&D results will make contributions of stability, enhancement and external reliability for R&D results.

Numerous of free-form buildings come up with external appearances using various types of free-form panels. If the panel types produced, transport and installation order and maintenance history are not properly managed, it is difficult to complete a given project successfully. For free-form building projects that satisfy 5 factors (proper time, place, price, product and quantity), a supply chain management technique is applied for distribution management of free-form concrete panels. In addition, the study listed the whole production process of free-form concrete panels and any necessary information, and suggested a basic model for the management. The study result will be a great help in effective distribution management of free-form panels for free-form building projects.

Korean core banking system has been redeveloped twice in the last 30 years with big-bang method, but still needs innovation to meet everlasting business changes. The objective of this study is to identify which decision criteria lead to replacement decision of core baning system in spite of its huge investment and accompanying business risk. For the study, we conducted a survey to 64 decision makers working in banks and IT service companies, and analysed the data using factor analysis and multi-regression analysis method of SPSS. As a result, we extracted statistically valid decision model with 4 major decision criteria, which are IT external, IT internal, IT ecology and Executive's will factor. Among them, we concluded only IT internal and IT ecology criteria give significant influence over the replacement decision of existing core banking system.
