As the technology of Smart City and Digital Twin is developing, techniques to integrate BIM data of infrastructure facilities into GIS are becoming more critical. Hence, this study aims to manage BIM data representing bridge and tunnel structures through the Industry Foundation Classes (IFC) standard and to develop a method to link these IFC-compliant files to the GIS standard CityGML without loss of information. We analyze the criteria for creating BIM data for bridges and tunnels by reviewing the BIM guidelines set by each client. We use these criteria to suggest methods for data management based on InfraBIM as a specific IFC class standard. Furthermore, we perform model analysis to determine the necessary design and construction field-appropriate model process and Level of Detail (LOD). From the model analysis, we conclude that the classified BIM models can be used as base data to generate BIM models of bridges and tunnels for facility management.

The public construction industry in Korea involves a variety of stakeholders, encompassing multiple layers of contractual relationships that crisscross between the State as project client and the contractors, as well as subcontractors. In such a hierarchical landscape, managerial crises of contractors involving bankruptcy or insolvency can result in unexpected damages for both clients and subcontractors. Accordingly, the applicable legal framework requires project clients to act as patrons in relation to making payments to subcontractors, and stipulates provisions pertaining to direct payments to subcontractors in order to promote the balanced development of the national economy in terms of the public interest by protecting small and medium-sized businesses working as subcontractors for large businesses. However, the relevant legal documents provide for different payment criteria and procedures from document to document, and leave room for variations in the interpretation and construction of applicable provisions, which leads to disputes and discrepancies in court rulings. For this reason, it is necessary not only to compare and analyze statutory provisions pertaining to direct payment to subcontractors, but also to review issues of contention in actual cases. This study aims to analyze issues in cases involving payment to subcontractors from the perspective of the project client overseeing and supervising the construction business. The conclusions from such an analysis will help to effectively resolve subsequent cases of a similar nature by suggesting a strategy to improve the relevant statutory provisions pertaining to direct payment to subcontractors.

It was well received that well grounded behavioral theories were important in the development of effective nutrition education programs, but there are only a few programs available for Korean women. The objective of this study was to develop nutrition education programs for childbearing-aged women in Korea. Based on the findings of the needs assessment for the program and theoretical backgrounds, we developed behaviorally oriented tailored nutrition education program including motivation (MT), modifying (MD) and maintenance (MA) stages. The key concepts of the stages were motivation promotion for MT, increasing behavioral capabilities for MD, and strengthening self-management and building favorable environmental condition for MA. The education program was intended to be need in individual nutrition counseling, but it could be well used for group education by developing materials using the relevant contents. The primary users of the program were nutrition educators, however it could be also used by clients as needed. The introductory chapter provided dietary assessment tools and nutrition education tips. MT chapter included subjects such as nutritional status screening, costs of inappropriate nutrition and weight management, benefits of eating right, and activities for motivation promotion. MD stage chapter dealt with topics of healthy weight, knowledges and skills for better eating habits and physical activity status, and activities related to setting tailored behavioral objectives. MA stage focused on facilitating self management skills and building helping relationships. Each stage underlined activities using various educational tools in order to promote active participation of the client (s). For better use of this program, it was recommended to conduct program validation study.

The construction industry has the most safety accidents of any of the domestic industries. Special care must be taken because disasters in the construction industry lead to social problems caused by huge property losses and casualties. As a result, there is a growing awareness of disasters occurring in the construction industry, and government departments are tightening their regulations on safety management. In particular, the OSHA (Occupational Safety and Health Agency) focuses on the expansion of protection targets and the clarification of responsibility in the full amendment OSHA. As a result, a study that focuses on the client's responsibility for safety management is needed. In this study, the project performance capability assessment of construction project management contractors, which is being carried out with uniform assessment criteria without considering the characteristics of the construction project, is considered and all the amendments to the OSHA are considered, and the factors were derived for improvement measures.

With the purpose of identifying clothing for persons with special needs one of new directions in Clothing and Textiles, this pater comparatively analyzed current curriculum and research trends related to this field between Korea and America. Questionaire was distributed to 25 Korean colleges with Clothing and Textiles department and 4 American colleges known for special clothing study. Questions regarded the name of course, level (grade), number of credit houre, prerequisits and supporting courses, subjects of lecture and projects, way of managing lecture and projects, evaluation system, other special characteristics. Resources for analyzing research trends are Thesis and Dissertations in Clothing and Textiles, Research Journal of Clothing & Textiles/Home Economics Association, College Professors' research reports collection, of both Korea and America. Years of publications are 1972∼1986 (America), 1978∼1988 (Korea). Findings are as follows; 1. Clothing for special needs can be classified into various groups; Clothing for physically handicapped, mentally retarded, elderly, unusual-sized, pregnant/nursing mothers, institutionalized, protective clothing, uniform/career apparel. 2. Management of coursework related to special clothing has several common characteristics specially in America; Building-up coursework, problem-solving orientation, cooperative team-preject, interdisciplinary approach, client-versus-designer preference, community involvement. In Korea, a few school only has special clothing coursework and its scope of study was very limited. 3. Majority of research reports done with the subjects of special clothing had made for physically handicapped people and the elderly. Protective clothing and uniform have recently been paid much interests. 4. Researchers had mainly concerned on Design and Construction Aspects and nextly on social-psychological aspects. However, in America, selection and care aspects and marketing aspects of special clothing have been very procuctive issues recently. 5. Study on clothing for special needs has several opportunities to be stressed and improvements to be strengthened. Opportunities included active participation to the welfare of community society, strong publicity of accurate professional image, share with business and industry, interdisciplinary approach and new job market. Improvements were discussed in terms of strengthening supporting courses/prerequistes, intensifying interdisciplinary cooperation, provoking strong community involvement and securing financial support and research funds.

As the construction production system is reorganized as part of the construction industry innovation plan, direct construction is expanding. According to this trend, this study analyzed the impact and problems of the expansion of direct construction through the position of the construction industry and a study of foreign cases. In addition, by diagnosing the impact of the measures to expand direct construction from various aspects, countermeasures were suggested to suitably apply the direct construction mandatory system. Also, for each alternative, effects and problems were evaluated through interviews with experts in policy/administrative and architecture fields. The alternatives for expanding and improving the efficiency of the direct construction mandatory system derived from this study are four items: granting the discretion of the client, differentiation by scale of construction, utilization of construction guarantee system, and introduction of flexible working group leader system. As a result of the expert interview, all of them were evaluated to have a positive impact directly and indirectly on the expansion of direct construction. This study contributes literature to the application of the direct construction mandatory system by examining the current status of direct construction, and suggests a direction for expanding direct construction through deduction of alternatives for applying the direct construction mandatory system and expert evaluation.

In response to the changing demands of ever competitive market, SK Telecom has built a new marketing system that can support dynamic marketing campaigns and, at the same time, scale up to the large volumes of data and transactions for the next decade. The system which employs Unix-based client-server (using Web browser interfaces) architecture will replace the current mainframe-based COIS system. The project, named NGM (Next Generation Marketing ), is unprecedentedly large in scale. However, both managerial and technical problems led the project into a crisis. The application framework that depended on a software solution from a major global vendor could not support the dynamic functionalities required for the new system. In March 2005, SK telecom declared the suspension of the NGM project. The second phase of the project started in May 2005 following a comprehensive replanning. It was decided that no single existing solution could cope with the complexity of the new system and hence the new system would be custom-built. As such. a number of technical challenges emerged. In this paper, we report on the three key dimensions of technical challenges - middleware and application framework, database architecture and tuning, and system performance. The processes and approaches, adopted in building NGM system, may be viewed as "best practices" in the telecom industry. The completed NGM system, now called "U.key System," successfully came into operation on the ninth of October, 2006. This new infrastructure is expected to give birth to a series of innovative, fruitful, and customer-oriented applications in the near future.
