The purpose of this study is to provide the basic guidelines of spatial and physical environment for the planning and design of clinical laboratory by analysing the extent of satisfaction of clinical laboratory scientists. The data for this analysis was gathered from March to May 2005 by the questionnaires of 208 clinical laboratory scientists who work in the 13 hospitals. All the collected data was analyzed by the SPSSWIN program. In this study, the satisfaction measurement tool was composed with 8 items and 5 score scale. The mean score of satisfaction for spatial and physical environment was 2.89 out of 5.0, "noise" was the lowest 2.40, "temperature and moisture of the lab." was 2.72, "lab. area, service area and administration area" was 2.77, "passageway space" was 2.94, circulation of workers was 2.94, "color of finish" was 3.19, "lighting of lab." was the highest 3.39. In conclusion, various factors, noise, temperature and moisture, clinical lab area, were evaluated to moderate dissatisfaction. Noise was especially the first serious problem in clinical lab. Considering the high growth of the number of tests, the planning of the clinical laboratory size should be considered not only to provide the optimal size but how it will correspond to the growth of the number of tests. Therefore the arrangement of each section need to be flexible in arrangement which is inevitable in expansion and reconstruction in the future.

A method for representing detailed design information of steel bridge member is proposed on the basis of the IFC model. As a first step, bridge related entities in the IFC-BRIDGE V2 and their functions are analyzed. In addition, design documents of steel bridge members are analyzed to extract information items that are not handled in the IFC-BRIDGE V2. It is recommended that several entities in the IFC-BRIDGE V2, such as ifcBridgeFibre, IfcBridgeReferenceLine, and IfcBridgeSection, should be properly relocated. In addition, IfcBridgeStiffener, IfcBridgeJointSystem, IfcBridgeDiaphragm, and IfcBridgeShearConnector are added as subtypes of IfcBridgeElementComponent for representing the stiffener, joint system, diaphragm, and shear connector, respectively. The added new entities inherit all attributes of IfcProduct which is linked with other resources: geometric representation, placement, material information, and so on. Thus, it is considered that a proposed in-depth IFC-BRIDGE model can be used more widely.

NATM as method of tunneling has been applied to construction of domestic subway, roads, rail way, water way etc. Accordingly, we have NATM's many drafts and constructional results, but many problems and accidents have occurred under construction of tunnel using NATM for shortage of technical data. Poorness of constructional improvement, systemic inconsistency etc. Especially, everyone was shocked at Gupo's train wrecking accident lately. The purpose of this thesis is presentation of means for setting technical problems, by looking into Gupo's train wrecking accident and home records that applying NATM in tunneling failed, to minimize future safety accidents we find that the general problems of home fifteen sites having occured accidents is badly geological survey, nonconfirmationi of base rock's state, formal measuring management, shortage of specialists, systemical discrepancy and that disregarding NATM's rules makes general problems. The results of this study are Summarised as follows : 1. We advise repletion of design standards to practice crosshole test for confirming connected rock base on vertical section of tunnel. 2. We advise to practice pre0boring and pre-grouting for a weak layer difficult in applying NATM. 3. We advise systemic improvements that field servicer can construct tunnel of his own free will considering base rock's state at tunnel . 4. We advise that specialist, who can make a conduct and supervise above mentioned items as well as measuring management, should be posted at field.

This study analyzed influence factors and the correlation among pollutants which affect occurrence of leaked pollution based on the long-term runoff flow and water quality investigation results to understand the characteristics of highway rainfall runoff pollution load. According to the result of correlation analysis on TSS (Total Suspended Solid) concentration, anteceded dry days, rainfall intensity, traffic volume and etc. as major influence factors of highway rainfall runoff pollution loads, the correlations were weak or scarce in most items. These results might be attributed that runoff pollutant concentration changes vary severely on changes of rainfall intensity and rainfall duration within rainfall and it is affected by disturbances of vehicles and street cleaning and etc. as characteristics of the highway. While Cu, Fe and Zn which are discharged with high concentrations out of heavy metals showed high correlation with particulate matter, organic matter(COD), nutrient(TN, TP), Ni and Pb showed relatively low correlation in a correlation evaluation by pollutant. Significant correlation with traffic volumes was not shown and TSS concentration even decreased in accordance with increase of the traffic volume. In the comparison with precedent studies, it was considered necessary additional analysis of the effects of rainfall section analysis, road type, disturbances of surface contaminants by vehicles, rainfall and climate conditions, surrounding terrains etc.

The objective of the present study is to analyze the results of the trial-test for the full-scale driving pump, which is arranged in the LCT (Large Cavitation Tunnel). Firstly, the reasons of selecting the final design pump are introduced in terms of the performance analysis in model tests. The trial-test items for the full-scale driving pump are measurements of output current/voltage at the inverter of the main motor and the flow velocity in the LCT test section. The test results show the increase in flow rate of about 10.7% and the decrease in pump head of about 26%, compared with those of final design-pump specification. The motor power has the margin of about 22%. The performance analysis for the full-scale pump is conducted using the commercial code (CFX-10). The delivered power calculated with CFX-10 shows good agreement with that extracted from the full-scale pump test. It is found that CFX-10 is useful to analyze a full-scale pump.

Purpose: The outbreak of Middle East Respiratory Syndrome(MERS) in KOREA has brought up the demands for ventilation guideline and regulations for healthcare facilities since most of the infection was spreaded inside healthcare facility. Currently KOREA has no ventilation guideline or regulations covering entire section of healthcare facility. The purpose of this study is to investigate current ventilation methods in KOREA healthcare facilities to in future, propose ventilation guideline. Methods: Research of foreign counties ventilation guideline and regulation for healthcare facilities were conducted for reference. Field investigation with survey of 21 healthcare were conducted to identify the ventilation system and operating methods. Additionally survey for healthcare workers were conducted to observe the recognition related to ventilation system in healthcare facility. Results: The result showed that most of foreign countries ventilation guideline and regulation suggests similar items to reduce the spread of infection and maintain good indoor air quality. The investigation results indicated that fixed guideline for ventilation in healthcare facility were required due to different ventilation operating methods. Survey result of healthcare workers has told us that ventilation guideline and regulation is needed to prevent further infection. Implications: Absence of ventilation guideline and regulations for healthcare facility in KOREA is an urgent issue.

This study was performed to develop a mobile functional pattern reflecting the characteristics of the middle aged women's lower body types based on the slacks construction components. The results and procedures obtained from this study were as follows; 1. The bodys measurement of the 252 middle aged women of 45∼59 years old were used to analyze the size and somato type. 2. For multiple analysis of the lower body types, horizontal and vertical section maps were obtained by sliding gauge method and extracted constructional factors of slacks. 3. The following condition was determined with both standing and moving position of body: (gradient of C.B.L/2)+3°and (back crotch extention)+2cm. 4. Development of new slacks pattern drafting was based on the result of data analysis. Trough the wearing test by the sensory evaluation, It showed that developed slacks pattern was judged better than existing patterns in items of comfort of comfort of silhouette and moving.
