Since its beginning the military has continued updating its equipments and facilities by modernizing and expanding them. However, with rapidly growing technologies and business management skills, the time for military facilities' evolvement seems unavoidable. The Defense Installations Agency (DIA) has come to a conclusion that application of BIM is necessary. Since its decision, the DIA has been researching the use of BIM and developing guidelines for its application. Nevertheless, the speed of instructions and practical implementation of its model have been behind its plan due to various reasons. To overcome its limitations, the DIA has come up with three-step-solution: basic experience, budgeting, and expansion. Due to numerous number of projects of BIM, it is almost impractical to implement all of them concurrently. The methodological approach of the research employs the Delphi survey method to quantitatively analyze qualitative information drawn from experts' opinions. By applying the Delphi survey method, the first round of the survey drew lists of constraints, BIM application scenarios as well as BIM promotion measures. Afterwards, at the second round of the survey, criticality of each item collected at the 1st round was analyzed to reach a conclusion. Finally, constraints against BIM application were analyzed, and BIM application scenarios and promotion measures for the BIM were introduced.

In the hazardous areas where explosive liquids, vapors and gases exist, electrical apparatus/equipment should have explosion-proof construction. The consuming of liquefied natural gas(LNG) has markedly increased in the industrial field, especially in aspect of some thermoprocessing equipment, boiler, dryer, furnace, annealer, kiln, regenerative thermal oxidizer(RTO) and so on. Because it has many merits, clean fuel, safety, no transportation/storage facility and so on. It is strongly recommend that the classification of hazards has to be decided to prevent and protect explosion which may occur in thermoprocessing equipment. In this paper, the operated thermoprocessing equipments in industrial area investigated and explosion risk assessment about LNG leakage from its facilities was performed through numerical calculation and computer simulation. Finally, we suggest the systemic/technical approach for safety assessments of thermoprocessing equipments consumed LNG fuel which are specially subjected to classification of hazardous area.

The purpose of this study was to provide basic information about the program space planning of skilled nursing facilities for the elderly in order to consider elderly health and diversity and to improve their rehabilitation ability. A mail survey was undertaken and 58 out of 78 facilities $(74.4\%)$ responded to the questionnaire. The answers of $56 (71.8\%)$ were used for analysis. The results of the study were as follows. Many programs, especially exercise, recreation, and facility events programs that require dynamic activity, were conducted in the lounge of the facilities because that area was wide with various equipments such as tables, sofas, and sound facilities, and did not require any huge movements of the elderly since it was very close to the elderly individual rooms. The art and human knowledge programs, managed with small groups, were peformed in separate program rooms or elderly individual room so that the elderly could pay attention to the programs. On the other hand, as for the design elements, the spaces for the art and human knowledge programs required good lightings and separate program rooms. The area of the spaces for the exercise, recreation and facility events programs was found to be the most problematic element, even though they were performed in the comparatively wide lounge. For future research, a field observation study is suggested to analyze the detail relations among the program spaces.

Regional information infrastructure(RII) plays an increasingly important role in determining the competitiveness of companies operating within the region. The purposes of this research are (1) to identify the types of RII demanded by the companies operating within Pusan and KyungNam areas in Republic of Korea, (2) to explain the levels of RII demand using variables including organizational environment, organizational strategy, and the importance of information systems for the organization, and (3) to examine whether the types of RII demand are different depending on the competition strategies that companies are pursuing. The most important type of RII that region companies demand is information systems personnel having knowledge in systems control, systems planning, communication network, database administration, and system construction. In addition, demanded are TSDN, satellite communication network, and shareable software and hardware. The levels of RII demand are different depending on the importance of information systems(IS) roles for the businesses. The more important IS role is for a company, the more sharable computing equipments and facilities are demanded. The importance of IS role is affected by the organizational environment and organizational strategy. The levels of RII demand are different also depending on the competitive advantages that companies are pursuing. Companies focusing on achieving short-term and direct benefits using information technology tend to have higher demands on sharable computing equipments and facilities as well as on information communication services. This research is explorative in nature One major limitation of this research, therefore, is that the plausibility of the postulated hypotheses was not examined simultaneously. This research is meaningful in that it first attempted to measure the demands of regional companies for RII.

This study was conducted to investigate the satisfaction of school dietitians with foodservice facilities and utilities in the Chonbuk area of Korea. Self-administered questionnaires were collected from a total of 22 dietitians. Statistical data analysis was completed using the SPSS v. 10.0 program. The results are summarized as follows. Among the 222 school foodservice systems, 68.5% of the schools prepared meals the conventional way and 31.5% prepared them the commissary way. Most of the school foodservice facilities were located on the first floor. Satisfaction with the location of the foodservice facility was not significantly different between the conventional and commissary systems. However, overall dietitian satisfaction with the foodservice facility locations was poor. Approximately 30% of the dietitians responded that one of the most important problems for foodservice management was the limited space and worn-out equipments in the kitchens. For dietitians' satisfaction on the types of facilities present, most schools had constructed dietitian offices, food storage facilities, cafeterias, rest rooms, dressing rooms, and preparation facilities. Yet, the amenities most often missing were storage facilities, preparation facilities, dressing rooms, rest rooms, etc. For overall satisfaction with the status of facilities and utilities, we found no significant differences between dietitians in the conventional(2.89) and commissary foodservice systems(2.86); however, the satisfaction level among the dietitians was poor. Therefore, governmental regulation agencies need to review and approve plans prior to the new construction or extensive remodeling of school foodservice facilities. Finally, content analysis was also conducted regarding the dietitians' opinions on foodservice facilities and utilities.
