In the current construction industry where various stakeholders take part, BIM Data exchange using standard format can provide a more efficient working environment for related staffs during the life-cycle of the building. Currently, the formats used to exchange the data from 3D-CAD application to structure energy analysis at the design stages are IFC, the international standard format provided by IAI, and gbXML, developed by Autodesk. However, because of insufficient data compatibility, the BIM data produced in the 3D-CAD application cannot be directly used in the energy analysis, thus there needs to be additional data entry. The reasons for this are as follows: First, an IFC file cannot contain all the data required for energy simulation. Second, architects sometimes write material names on the drawings that are not matching to those in the standard material library used in energy analysis tools. DOE-2.2 and Energy Plus are the most popular energy analysis engines. And both engines have their own material libraries. However, our investigation revealed that the two libraries are not compatible. First, the types and unit of properties were different. Second, material names used in the library and the codes of the materials were different. Furthermore, there is no material library in Korean language. Thus, by comparing the basic library of DOE-2, the most commonly used energy analysis engine worldwide, and EnergyPlus regarding construction materials; this study will analyze the material data required for energy analysis and propose a way to effectively enter these using semantic web's ontology. This study is meaningful as it enhances the objective credibility of the analysis result when analyzing the energy, and as a conceptual study on the usage of ontology in the construction industry.

The radical treatment of uterine cervical cancer by interacavitary radium or cesium, in combination with teletherapy are well known. Although the result of such treatment should not give rise to complacency, problem of radiation exposure to medical staff had not been resolved. Fortunately, many attempts have been made to reduce this hazard, most of which take the form of afterloading applicators with a suitably shielded radioisotope. In order to avoid hazardous radiation exposure to staffs concerned with brachytherapy, RALS using high intensity source of Co-60, have been employed at Yonsei Cancer Center since May, 1979. It allows rectal and bladder doses to be kept low, while maintaining a satifactory usual dose distribution of the other type of applicators, and the short treatment time allow four or five patients to be treated per hour. It also removes much patient's discomfort and the difficulties of nursing these patients. Since the first introduction in Korea, over seven hundred cases with various stage of uterine cervical cancer have been treated on a radical basis at this center last 4 years. These authors have strongly attracted attention to the results in terms of local control rate, survival s and morbidity compared with those of conventional low dose rate radiotherapy. Retrospective interim analysis of data was preliminarily accomplished through the labored follow-up study of 340 cases treated during initial 2 years and the radiobiologic standpoint of high dose rate intracavitary irradiation will be discussed.

This study was conducted to follow the patient referral system operated from the primary health care facilities to the hospital in a rural area of Korea. The subject for this study was sampled from a community health development project carried out by the Korea University in Yeoju Kun, Kyonggi Province. The data of referred patients from primary health care facilities were collected during the period from January 1989 to December 1989. The data was sorted out by a computer system using Database package. The results of this study were summarized as follows: 1. Characteristics of the referred patients were: males $32.0\%$. and females $68.0\%$. The more elderly of the patients visited to the hospital after having been referred there by CHPs or public physicians, $25.9\%$ has been to hospital on at least one previous occasion as against $74.1\%$ for whom it was there first visit. 2. The majority of patients who were referred to a hospital where: medicine $44.3\%$ and orthopedics$16.4\%$, major diseases were : diseases of digestive system $(21.3\%)$ ; symptoms and ill defined conditions $(17.3\%)$ ; diseases of the muscular skeletal system and connective tissue$(14.2\%)$. chronic illness was $82.0\%$ and acute illlness was $18.0\%$. 3. From Community health practitioners more patients referred than the public physicians. Categoris of diseases of the referred patients were different between community health practitioners and public physicians. Due to the. respective differences between the medical restrictions put on the nursing staffs at the community health practitioners and public physicians. From this study it was recommended to define the reason of differences between ~he two groups in futher study. Study as to 1) why one group should be referring more for hospital treatment than the other. And 2) why the two agencies should be referring different diseases.

The purposes of this study were to provide evidence concerning the effects of Emotional Leadership and examine the impacts of Emotional Leadership on employee-related variables which were 'job satisfaction', 'organizational commitment', 'organizational performance', 'turnover intention'. A survey was conducted from August 23 to November 3, 2005 to collect data from kitchen staff(N=611). Statistical analyses were completed using SPSS Win(12.0) for descriptive analysis, reliability analysis, factor analysis, t-test, correlation analysis, cluster analysis and AMOS(5.0) for structural equation modeling. Kitchen staffs gave high point to their leader in the Emotional Leadership competence 'Optimism: seeing the upside in events' and 'Adaptability: flexibility in handing change' and gave lower point in the Emotional Leadership competence 'Inspirational leadership: guiding and motivating with compelling vision'. Employees' job satisfaction on 'coworker' were relatively high. However, the extents of satisfaction on 'payroll', 'promotion', 'work environment' were relatively low. The organizational commitment score was higher at 'loyalty' factor than 'commitment' factor. the test of hypothesis using structural equation modeling found that Emotional Leadership produced positive effects on job attitude and job performance. In conclusion, this study has identified that the Emotional Leadership effects on their organizational performance and attitudes toward their job.

Endocrine-disrupting chemicals (EDCs) are chemicals present in the environment that interfere with the normal hormone functions of various organisms and cause genetopathy, deformities, or cancer. This study surveyed the awareness of EDCs with 242 cooking staff at 242 meal service facilities for children located in a part of Gyeonggi Province. To minimize infants' exposure to EDCs, the subjects were provided with information on EDCs for two months. The behavior of reducing exposure to EDCs was analyzed according to the awareness of EDCs and work ethics. In addition, the effects before and after being provided with the information were evaluated. According to the results, the levels of awareness of EDCs and work ethics' scores of the cooking staff were high with 3.95 and 4.39 points, respectively, out of five points. In addition, a higher awareness of EDCs and a higher work ethics' score were associated with an improved behavior of reducing exposure to EDCs (P<0.05). The overall cooking and cleaning behavior for reducing exposure to EDCs showed improvement after providing information (P<0.01). Therefore, these results suggest that it is important to provide continuous education to enhance the awareness of EDCs, work ethics, and behavior to reduce exposure to EDCs.

Patients administered radioisotope for medical purposes are regulated by each country to quarantine them until their body's radioactivity contents decrease below release criteria. To predict the quarantine period and provide it to medical staffs and patients, it is necessary to approach the assessment of the exposure dose of persons due to patients in a realistic manner. For this purpose, a whole-body effective half-life should be applied to the dose assessment equation instead of the physical half-life. In this study, we constructed a bio-kinetic model for each nuclear species based on the ICRP publication to obtain a whole-body effective half-life of 10 unsealed gamma-ray emitting nuclei from the notification of Nuclear Safety and Security Commission, and calculated the effective half-life mathematically by simulating the distribution of the radioisotope administered in the whole body as well as each organ scale. The whole-body effective half-life of $^{198}Au$, $^{67}Ga$, $^{123}I$, $^{111}In$, $^{186}Re$, $^{99m}Tc$, and $^{201}TI$ were 1,93, 2.57, 0.295, 2.805, 1.561, 0.245, and 2.397 days respectively. However, it was found to be undesirable to offer a single value of the effective half-life of $^{125}I$, $^{131}I$, and $^{169}Yb$ because the changes in the effective half-life show no linearity. A bio-kinetic model created for the internal exposure assessment has been shown to be possible to calculate the effective half-life of radioisotopes administered in the patient's body, but subsequent studies of radiolabeled compounds are required as well.
