While the plant projects grow bigger and global attention to the plant is increasing, efficient space arrangement is not working in plant project because of the complex structure in installing the equipment unlike the construction project. In addition to this, presently, problem in installation process caused by the disagreement between floor plan and real spot is rising. Therefore the target of this research is to solve the problems and reaction differences, caused by changing the space arrangement in installing the equipment of plant construction. And this research suggests the equipment arrangement method for construction and related processes. To solve the problem, 3D cloud point data of space and equipment is collected by 3D laser scanning and the space matching is operated. In processing the space matching, data is simplified by applying the octree algorithm. This research simplifies the 3D configuration data acquired by 3D scanner equipment through the octree algorithm, and by comparing this data, identifies the space for target equipment, and finally suggests the algorithm that makes the auto space arrangement of equipment possible in construction site and also suggests the process to actualize this algorithm.

In or to generate high electric power in increasing demand, power station should operate facilities to meet requirement. The scale of electric power equipment is increasing in both size and complexity. With unexpected accidents at power facilities or power stations happening, substantial socioeconomic losses in an industrial society is caused. A major cause of unexpected accidents is deterioration of dielectrics, isolating two conductors electrically. In order to detect the deterioration processes of power cables, the operation status of power cables should be monitored on a regular basis. We have invented and installed equipment at Korea Western Power Co., Ltd., located in Taean, in order to predict and prevent the deterioration status of dielectrics destruction of power cables. The main line in Y-connection to the secondary coils of transformer delivers electric power to the external devices. The equipment we developed is the one measuring insulation resistance of cables operation in on/off status with respect to the main line. We present the equipment in terms of operation and configuration of hardware side.

In this study, based on SSOP (Sanitation Standard Operating Procedure) for HACCP in Food Sanitation Act, essential facility, equipment and documentary records for HACCP implementation were identified. Usage and adoption of these devices at Korea Food ＆ Drug Administration appointed HACCP foodservices ("Appointed"), voluntary HACCP applying foodservices ("Voluntary applying") and HACCP non-applying foodservices ("Non-applying") have been compared. Total 46 contract foodservices were surveyed： 13 "Appointed" (65％ of nation-wide all appointed food services in February, 2002),17 "Voluntary applying" and 16 "Non-applying". For usage and adoption of facility and equipment, 18 out of total 27 surveying items showed significant differences at the three foodservice groups (p＜0.01 or p＜0.05). Specifically, following items showed lower usage than 70％ in the "Appointed"： ′A trench including grease trap′, ′3-compartment sink with hot water′. Regarding CCP monitoring tool installation, 8 out of total 9 items showed significant differences among the groups (p＜0.01 or p＜0.05). For the usage of 10 documentary recording items for HACCP application log, 7 items showed significant differences among the groups (p＜0.01 or p＜0.05). Resultantly, most of those essential facilities, equipment and documentary records ;were used only in the "Appointed". The limited usages of those were showed for the "Voluntary applying" where the dietitian answered they applied HACCP voluntarily. The "Non-applying" didn′t have many surveyed items.

The interest in the Building Information Modeling (BIM) technology has risen remarkably due to the effects on construction work period reduction, cost reduction, work safety improvement, and other factors. In civil engineering field, BIM applications mainly focus on data modeling and virtual construction. In this study, we present the BIM-based virtual construction and analyze the effects of BIM for the railway facilities so that the conventional approach to the equipment operation plan can be improved in order to prevent safety accidents which can result from unclear information during the operation plan. The BIM-based virtual construction technology is applied to establish the construction plan for the site with constraints, the installation of steel girder needs to be completed, avoiding interference with the existing high-speed railway operation within a given limited time. A virtual construction model consisting of topography, structures, equipments, and avatar was built and more detailed model, including safety guard rails, was then created. Specifications of the construction equipment were input as a database, and the virtual construction model was manipulated in the equipment operation planning. Through the BIM-based virtual construction, including the verification of alternative construction method, 311 million won was saved and the construction period was shortened by 87 days compared to the original plan. In addition, it was shown that the interest and participation of the construction workers can be increased by providing the 3D virtual scene for real construction work and various safety hazards occurring during equipment operation can be effectively removed in advance by the interactive worker education.

If remodeling is defined as activities that restore the overall function of a building up to the standards currently demanded rather than as a simple replacement or repair of old facilities and equipment, the main task of remodeling should be the reduction in differences between areas, establishment of a functional linkage between departments and setup of a smooth circulation system. Therefore, this study is an analysis of remodeling strategies and construction processes to resolve major tasks of remodeling. Through this research we acquire concluding remarks. 1) The remodeling strategies of equipment-intensive areas can be divided into two measures: utilizing the existing buildings (the main buildings) the most, and of concentrated relocation in the new buildings. The former method is advantageous in that the main building serves as a center in hospital layouts because concentrated placement of the diagnosis/ treatment area and the supply area benefit the overall operation in terms of functions. However, the measure has limits in that it is difficult to install the facilities and equipment of the new demands due to the low ceilings, which serve as a potential challenge in future growth and changes. 2) The latter measure is the one in which equipment-intensive areas and the areas that are absolutely short of space are first placed in the new buildings while other areas (the outpatient area, the administration area and the miscellaneous areas) are in the existing building (main building). Given the possibility of development In the future, concentrated placement in the new buildings can be said to be more effective order to actively address future growth and changes.

The purpose of this study was to investigate the equipment ratio of sanitary facility/equipment as well as the sanitary management performance level at foodservice of correctional institutions in Korea. For this purpose, a total of 47 questionnaires were distributed to dietitians working at correctional institutions during the period from March 20th to May 18th of 2008. A total of 38 questionnaires (response rate 81%) was analyzed using SPSS (windows ver. 14.0). The majority of the respondents were females (65.8%), 35 years or older (55.3%), with 7 years or longer experiences (65.8%), and with education level of university or higher (60.5%). Among the institutions, 39.5% had less than 500, 28.9% had 501 or more but less than 1,200, and 31.6% had 1,201 or more inmates. The equipment ratio of the sanitary facilities/equipment was 49.7%, which was relatively low. Most dietitians perceived 'limited availability of facilities and equipment' and 'the lack of support from financing department' as the major barriers in implementing a desirable sanitary system. On the other hand, perceived sanitary management performance was rated by the respondents as being between 2.55 to 4.50 (5-point Likert scale)-'Cleaning hands properly as specified' showed the lowest performance, whereas 'Sampling preserved meals by standard methodology' showed the highest. The results of this study suggest that a sanitary education program designed for inmate food handlers is needed for successful sanitary management.

This study was performed to investigate the sanitation management and the sanitation knowledge of managers in military foodservice by questionnaires and inspection of foodservice facilities. Thirty managers working in military foodservice were given questionnaires and the related facilities located in the northern part of Kyeongki-Do, Korea were inspected. Most of the facilities(76.%) were built more than ten years ago, they are now decreptit and the internal temperature was high with poor ventilation in the kitchen. An education program on sanitation was conducted less than four times a month (63.3%) while the education materials and resources from the upper-unit(80%) along with their self-renewment of data was poor(once a month, 60%). In the sanitation knowledge examination, the percentage of correct answers were 76% in terms of facilities, 72% in terms of personal sanitation, 71% in terms of receiving and storage, 63% in terms of the environment and 57% in terms of the cooking process. The results of this study suggest that the modernization of foodservice facilities and equipment, along with additional sanitation machinery and equipment, a guaranteed working environment and upgraded sanitation education will be required to improve the sanitation management in military foodservice.
