The purpose of this research is to develop an Integrated Water Resources Evaluation Index (IWREI) which can used to assess the performance of water resources projects in a regional perspective focusing on three major sectors including water use, flood, and river environment in water resources policies. The IWREI is estimated by integrating the Water Use Vulnerability Index (WUVI), the Flood Vulnerability Index (FVI), and the River Environment Vulnerability Index (REVI) which represent the vulnerability in each sector. These indices consist of total 26 indicators selected from the pressure indicators representing the causes of damages in water use, flood, and river environment, the state indicators and the response indicators. The estimated index describes the vulnerability and effectiveness of policies with five levels: Low, Medium Low, Medium, Medium High, and High. The results of evaluating total 115 hydrological units in Korea using the WUVI, FVI, REVI, and IWREI indicate that the project effectiveness in water resources policies is clearly verified by the improved index results compared to the past (early 1990s). Regional vulnerability and evaluation indices developed in this research could be used to establish goals of water resources policy and to select priority regions for project implementation.

Purpose: The purposes of this study were to provide information about safe actions during the practice of dental technology, promote belief in safe actions among the students of dental technology, and reinforce their knowledge about how to act safety. Methods: Open questions were asked to 120 sophomores majoring dental technology to understand the target group's belief about safe actions. Following the instructions by Ajzen & Fishbein, the collected data were grouped according to similar beliefs. Those beliefs of the highest frequency were given a priority and got to represent the belief level of the target group. Even with belief changes, however, they would not be able to practice safe actions if they had no knowledge about how to do safe actions. For desirable behavioral changes among the students, the students were then asked to discuss the current state of safety accidents and issues focusing on the materials and processes used in the practice and give presentations regarding the subjects to identify risk factors. Then the identified risk factors were used to devise the program contents so that the students could practice safe actions through accurate behavioral approaches and belief changes by educating them about how to act safely by the practice processes and the involved materials and devices. Results: Not only do the students of Dept. of Dental Technicians have difficulties with the complex practice processes while practicing to make dental prosthesis, but they are exposed to the risk of accidents as they're poor at dealing with the materials and devices. Although there is a definite need for accident prevention education programs before practice, the reality is that the school doesn't the schoosuch education. Based on the judgment that an education program designed to reinforce belief for behavioral changes would generate effgrams results, an education program was developed by applying the Theory of Planned Behavior(TPB). Along with their beliefs, the current state of accidents n. Basepractice, demand for safety education, and practice level of safe actions were used to device the contents of accident prevention education and to develop an accident prevention education program for dental technology. Conclusion: The study presents an accident prevention education program developed to reinforce dental technology students' beliefs and knowledge and to help them do safe actions during practice.

The purpose of this research was to figure out what impacts technology and market orientation have on technological cooperation and management performance by analyzing the factors of technological cooperation aimed at firm's product development. In addition, the research was purported to help CEO and policy makers make better decision about technological cooperation by means of the systematic examination on the impacts that different factors of technological cooperation have on the management performance. For this purpose, it was analyzed first what kind of technology or factors of market orientation might affect manufacturer's technological cooperation. From the analysis, it was found that technological cooperation is affected by the factors of market orientation, which means that a firm needs strategic technological cooperation by taking into account multi-dimensional factors of technology and market when the firm aims at developing technology and market orientation. Second, it was analyzed whether a firm's technological cooperation has an impact on its performance. The results indicated that the impact differs in the degree of process of technological cooperation, implying that managing firm's technological cooperation is important in order to improve the quality of management performance. Third, it was analyzed through what structural relations technology and market orientation could exercise impacts on management performance. It was discovered from the 1analysis that technology and market orientation have an impact on management performance. To improve management performance, it seems essential to determine the order of priority among technology and factors of market orientation.

A geographical information systems(GIS) was a useful aid in the assessment of urban nonpoint source pollution and the development of a pollution control strategy. The GIS was used for data integration and display, and to provide data for a nonpoint source model. An empirical nonpoint source loading model driven by land use was used to estimate pollutant loadings of priority pollutant. Pollutant loadings were estimated at fine spatial resolution and aggregated to storm sewer drainage basins(sewershedsl. Eleven sewersheds were generated from digital versions of sewer maps. The pollutant loadings of individual land use polygons, derived as the unit of analysis from street blocks, were aggregated to get total pollutant loading within each sewershed. Based on the model output, a critical sewershed was located. Pollutant loadings at major sewer junctions within the critical sewershed were estimated to develop a mi t igat ion strategy. Two approaches based on the installat ion of wet ponds were investigated -- a regional approach using one large wet pond at the major sewer outfall and a multi-site approach using a number of smaller sites for each major sewer junction. Cost analysis showed that the regional approach would be more cost effective, though it would provide less pollution control.

The periodic Quality Assurance (QA) of each radiation treatment related equipments is important one, but quality assurance of the radiation treatment planning system (RTPS) is still not sufficient rather than other related equipments in clinics. Therefore, this study will present and test the periodic QA program to compare, evaluation the efficiency of the treatment planning systems. This QA program is divided to terms for the input, output devices and dosimetric data and categorized to the weekly, monthly, yearly and non-periodically with respect to the job time, frequency of error, priority of importance. CT images of the water equivalent solid phantom with a heterogeneity condition are input into the RTPS to proceed the test. The actual measurement data are obtained by using the ion chamber for the 6 MV, 10 MV photon beam, then compared a calculation data with a measurement data to evaluate the accuracy of the RTPS. Most of results for the accuracy of geometry and beam data are agreed within the error criteria which is recommended from the various advanced country and related societies. This result can be applied to the periodic QA program to improve the treatment outcome as a proper model in Korea and used to evaluate the accuracy of the RTPS.

The world has been rapidly restructured in an agenda of national security from center of military strength to that of economic strength since the post cold-war era China military leadership-division carried out RMA through learning of a lesson from Gulf war in 1990 -1991 and Iraq war in 2003, thus the leadership-division made an attempt to convert the military system to a technical intensive system. The principle based on RMA of China military is (National defense strategy) drafted by the central military committee 1985 and (Four modernization general principles) 1978. China has introduced Russian high-technological arms and equipment in order to build up the military arms greatly thanks to an economical development, and they take pragmatism line as chinese socialism with their strategy to make secure a position as military powers such as they successfully launched a manned spacecraft and are building an air-craft carrie and soon. USA has a theory of dichotomy whether a country is a cooperator for USA, or not. and also enemy or friend since 9.11terror, thus USA is different from their direction of police. This is because USA stands a position as the superpower of the supremacy hegemony of the world. We must be carefully aware that USA considers as important area for Middle east, West south Asia, Central Asia and Northwest Asia to meet the demands of 2lcentury. Accordingly, the focus of USA's military strategy will be probably concentrated at the above mentioned four areas. On the other hand, USA enjoys such a superpower position due to collapse of USSR which was the past main enemy since the post cold war era. We could give an conclusive example as fact that USA has recurred to unilateralism But USA carry on the military operations to the terror groups at global around by converting thje military strike strategy to pre-emptive strike strategy since9.11 terror, 2001. USA seeks for transformation to the mobile military forces with light-quantity oriented in order to carry on such the military operations and makes progress GPR, And the USA forces in Korea makes progress a military renovation as part of such a military strategy. On the other hand, USA promotes the measures of choose for the countries standing at the crossroads of strategy and carries forward a main scheme of provision for four priority aims that the leaders of a hostile country and mis-country shall be prohibited from use and obtainment of weapons of mass destruction. Accordingly, this treatise found out a significant meaning to have an effect on the national security in the korean peninsula.

Objectives: To propose the basic data for the development of the optimum health promotion program (HPP) for the workers in a petrochemical industry complex. Methods: The subjects were 553 workers who worked at the six plants in a petrochemical industry complex. From February to March 2003, questionnaire survey was conducted by the nurses with occupational health specialty about the life styles, interests, self-cognitions, practices of health behavior, subjective symptoms thought to be related the working environments, burden to the own health, needs and intentions to participation of the HPP. Data analysis was done using SPSS program (ver 10.0) with ${\alpha}=0.05$ of statistical significance. Results: The mean age and tenure of the subjects were 39.7 years and 14.2 years, respectively, and proportion of smokers was around 50%. Two of third (66%) satisfied their own job, and 58% recognized themselves healthy. The most frequent health behavior were exercise (60%) and regular health check (87%) in individual and job based, respectively. About half of them (58%) had at least one of the symptoms thought to be related the working environments, and the most frequent one was odor (21%). These symptoms were more frequent in case of the shorter career. The needs of HPP was relatively higher in exercise (66%), cancer prevention (51%), stress control (47%), and intention to participation was also the highest in exercise (64%). Job satisfaction was higher in case of the higher interests and cognitions to their own health, and thought that the ownership's interest to workers' health be high (p<0.01), but no associations with the subjective symptoms. The mean level of burden to the own health were $14.1{\pm}13.9$ of physical, $11.7{\pm}13.6$ of emotional, $9.1{\pm}10.7$ of behavioral as out of one hundred. They felt the more burden in case of office workers, the lower interests and cognitions to their own health, the lower satisfaction to their job, the frequent drinking group, and complained the subjective symptoms (p<0.05). Abnormal results of the regular health check was higher in the frequent drinking group (p=0.083). Conclusions: For the optimum HPP for the workers in the petrochemical complex, the ownership's interest to workers' health would be enhanced, and the priority would be focused on exercise and drinking habits control.

This study analyzed the characteristics of the entries at the design competition for the Hoehyeon section of Namsan from a perspective of the Historic Urban Landscape and made suggestions from them. Hoehyeon, located at the foot of Namsan, is the most changing site in the park and Seoul City Wall. Recent excavation of the old city walls of the Joseon Era has uncovered evidence of the Japanese occupation period, making it a site where park facilities in modern and contemporary history coexist. The frame analysis has been made by the concept of the Historic Urban Landscape, the methods of approach, specialists' discussion and the guidelines of the competition. The entries were analyzed by classification of the understanding of the spatiality and cultural diversity, the recognition of the periodic layers of time, and the design implementation, the preservation, the park plan, and the future management plan. From a perspective of an Historic Urban Landscape, this study has found that each entry placed priority on the objects for preservation and suggested creative involvement and comprehensive designs for the preservation and the park plan through the understanding of the spatiality and cultural diversity and the reflection of the periodic layers of time in the designs. This study provided two implications. Firstly, there was a possibility for new recognition and the methods of approach for preservation and development. Secondly, the basic plan for the Historic Landscape should be established through research and mapping for the preservation and management of objects in Seoul having valuable historic variability. Further study for resident participation and the process by network from public to private should be taken. This study looks forward to the consideration of the direction for the design plans of places with historic and cultural value.

Industry development caused numerical and quantitative increase of noxious chemical substances that contain risk assessment in water resources. For use of efficient water resources a pre-treatment of contaminant source which is flowed in water resources is recognized in essential process. Therefore, the discharged water quality from discharged company began to control contaminant by total amount of pollutant in domestic. However, to estimate closely chemical substances it is not proved up to now, monitoring is very important. This study achieved a monitoring of micro noxious chemical substance by fiber and chemistry industrial wastewater inflow to examine risk assessment of the water system of Nakdong river. Chloroform was measured highest among volatile organic compounds (VOCs) that the results of water quality of influent and effluent are detected from 7 companies of study area. The other side, because measured value of detected chloroform is indefinite detection level in the same company, it is difficulty in management of water quality. However it may not be much effects of the water system of Nakdong river because these company's effluent is high treatment efficiency of chloroform (more than 88%) in sewage treatment plant. On the other hand, in the investigated results for the European Union specified priority substance that is detected to relationship influent and effluent from fiber/chemistry associated industries, these substances were not detected and domestic data was hardly referred. Therefore, data construction of continuous monitoring about this water quality may have to be achieved certainly to utilize as country policy.

Most of all Castle Remains in Korea were built on an axis of development with a scale of great magnitude. Because of its characteristics, the restoration and conservation plans should be phased in over medium and long term. There is no standards for evaluating the value of Castle Remains to set up the restoration and conservation sections. Some plans were set up through the value evaluation of its Castle Remains but those plans didn't have Evaluation System and different weight depending on different environment between Sanseong(mountain fortress) and Eupsung(fortress built in villages). To solve the limitation of Evaluation System of Castle Remains, this study try to approach in the Evaluation System methodology for selecting restoration sections. The results of its study follow below. First, this study drew the Evaluation Indices for selecting restoration sections of Castle Remains. There are three kinds of Elements(upper Index) and nine kinds of Evaluations(low Index). Second, Calculation of weight index by index on the questionnaire survey from expers through the relative importance analysis of AHP. Third, This study suggests the specific Evaluation System according to types; Sanseong(mountain fortress) and Eupsung(fortress built in villages);. Therefore, this study suggests standards to select the priority list for the restoration and conservation plan process and it can be used one of important standards in future plans.
