Since the results of the election forecasting survey that was executed jointly by T.V. stations and survey research companies in the 16th Korea General Election(April 13, 2000) had many errors, the reliability of the election forecasting survey was greatly damaged. Therefore, in order to recover the reliability and to increase the accuracy of the election forecasting survey I the future, we figure out the sources of the survey\\`s errors and suggest methods of reducing them through deeply analyzing the forecasting data from many angles. In addition, we discuss some problems and an improvable direction on exit poll executed for the first time.

The fixed abrasive pad(FAP) has been introduced in chemical mechanical polishing(CMP) field recently. In comparison with the general CMP which uses the slurry including abrasives, FAP takes advantage of planarity. resulting from decreasing pattern selectivity and defects such as dishing due to the reduction of abrasive concentration especially. This paper introduces the manufacturing technique of $Al_2$O$_3$-FAP using hydrophilic polymers with swelling characteristic in water and explains the self.texturing phenomenon. It also focuses on the chemical effects on tungsten film and the FAP is evaluated on the removal rate as a function of chemicals such as oxidizer, catalyst, and acid. The removal rate is achieved up to 1000A1min as about 70 percents of the general one. In the future. the research has a plan of the advanced FAP and chemicals in tungsten CMP considering micro-scratch, life-time, and within wafer non-uniformity.

With the change of funeral customs, funeral facilities in general hospitals are prevailing in recent years. In order to cope with this change, many funeral facilities are built in hospitals in significant sizes. Architectural considerations for funeral facilities are to be developed. In this research, based on the case analysis of the funeral facilities which are in operation, characteristics of spatial composition in those facilities are analyzed from the viewpoint of users and the result is organized in to a set of proposed guidelines for their space design. The analysis includes definition and classification of functional space, plan type, circulation and spatial atmosphere.

The purpose of this study is to suggest the data Structure System for the architectural planning in ward of general hospital. The important result and advantage of the system such as HcCad-System for design and plan of wards are as follows; At first, the system useful for communication medium and instructional tool for ward planners and designers. Secondly, fast and economical evaluation are obtained through the study of experimental simulation. Finally as a new tool in architectural field, system helps to enhance the relationship between computer and human.

Recently the hospital infection with misappropriation of the antibiotic and absence of knowledge is aincreaseing trend. For this, medical treatment is confronting infection management guide. But so far there is no accurate standard or countermeasures. Since early 1990 Nosocomial Infection has not been looked over, although there is serious problem. After 90's understanding seriousness of Nosocomial Infection, many investigations have been done, but the relations of medical facilities were hardly investigated. This thesis shows the relation between facilities and Nosocomial Infection by documental references and the direction for intensive care unit through survey the recent general hospitals.

A new operational concept for the CNS/ATM using the digital data communication technology and satellite navigation system is being implemented globally and the United States is the first country to apply UAT ADS-B system for general aviation. Korea also has plan to build ADS-B system for aeronautical surveillance to monitor low altitude flight of light aircraft and ultra-light flying device and the research to develop UAT ADS-B equipment is being carried out. This paper presents the application method of UAT ADS-B to support test operation with case study of foreign UAT ADS-B operation and survey of domestic environment.

Korea has experienced many changes since modern hospitals started to be built. Among these changes, interest in 'Promotion of Curing environment', which is the most fundamental one of the hospital functions, has increased more and more. The lobby makes the first impression of a medical building and that is an important function. Recently, the lobby became highly valued not only as a waiting area or a pathway only but as a cultural area. The lobby is considered simply as a complex and busy area because it plays an important role in the building' communications and access systems and has various uses and functions. Based on the concept of curing environment, the lobby can be planned as a facility combining culture and medical functions by applying multi therapy.

The purpose of this study is to suggest reasonable composition and layout of a nurse station and attached spaces-which are central sector of patient caring in the inpatient department- in the view of funtional efficiency. The method of this study is examining other studies and case study of inpatient department in general hospitals. through this research we find out the plan type of inpatient department and layout of nurse station and attached spaces in the view of 'the efficiency of circulation' and 'the easiness of observation' . It is also found out that the nursing delivery system effects to the composition and layout of nurse station attached spaces. Therefore, the efficient design of inpatient department by this study can accomplish 'patient-focused' medical environment and aid to develop their health.

The Purpose of this study was to enhancing sustainable participation of community gardeners by comparing general apartment complex with public lease apartment complex by drawing indices for quantitative research. This research carried out interviews and statistical research with 319. The results revealed statistically difference between 2 types of apartment, and satisfactions and intention of continuous participation is also different from each sustainable in participating in community garden are also different from each type. Overall, however, participation of female citizens, public assistance, area of plot, and effectiveness of exchange can enhance participants' continuous participation.
