Because of urbanization, Industrialization and expansion of transportation network, blasting works are recently increasing in construction field. The blasting work influences environmental effects to residents and the safety of facilities around the working place, so the development of blasting technology is needed to reduce the damage to residents. The blasting mechanism in the hole was studied and tested in the blasting sites by the difference of diameter between explosives and drilling hole, which is named by the decoupling effect. This effect was tested by changing the medium between explosives and hole wall in three working sites(railway, highway and industrial complex). The vibration velocity of blasting was recorded and vibration equations were produced by regression analyses. Finally, the structure separation distance was derived using these equations. The testing results show that the specific gravity of medium is larger, the separation distance is smaller and the duration time of blasting is shorter in case of large specific gravity of medium, so the vibration effect stops more fastly in the water compared with the air.

This thesis investigated disabled students' actual status of applying for university libraries. This thesis investigated how many times the university disabled students utilized the libraries, if facilities, apparatuses, materials, and regular employees were operated properly, and if they were established actually on the target at thirty private university libraries located at Seoul and Gyeonggi regions in operation of specially screening the objective students for special education in 2008. The investigation found that the general operation level of university libraries for disabled students were less than "medium"(average 2.38). As for utilization ratio, the most university students responded that "they didn't utilize libraries so many times(60%)". As for the response ratio of university library facilities and services, the most university students responded, "very insufficient", 99 items(32.27%), and the least university students responded, "very excellent", 28 items(7.0%). On the other hand, as for the analysis of each field, building facilities, in all of the items, were established more than "medium"(average 3.26), but material preparation level(average 1.8 point), employee education for softly supporting disabled students, and library utilization education on the target at disabled students(average 1.87) were less than "insufficient". Especially, the field of service was "insufficient level"(average 2.48), and standard deviation was more than 1.4. Manpower stationing and material delivery services have the biggest standard deviation between universities. So, this investigation found that university libraries reformed access to facilities a lot, but that its level of fundamental policy for library, such as materials, manpower, and the education on utilization, were in insufficient level.

Current medical delivery system in Korea has been distinguished into three types; primary medical facilities, secondary facilities, and tertiary facilities since 1989. This system prevents the waste of medical resources along with the maintenance of balance according to the medical treatment subjects. However, it is inevitable that the imbalance of the medical services among regions has been generated due to the concentration of the medical facilities on large cities. In this regard, this study attempted to evaluate the quality of the primary medical services, emphasizing accessibility and convenience targeting Jinju city, a small and medium-sized city, based on the distribution characteristics of the space. The study results show that cohesion index about the spatial distribution of the primary care facilities was 0~0.25. It conducted a correlation analysis between the location of the hospitals and users, based on the study results. Finally, it is demonstrated the correlation between the location of the hospitals and users tended to be low, while, the cohesion of the Oriental medicine clinics was high in other treatment subjects, and the accessibility to the Oriental medicine clinics was the highest because most Oriental medicine clinics were distributed to the places where users were many. However, on account that the locations of the medical facilities and users were varied in other treatment subjects except for the Oriental medicine clinics, problems were generated in terms of the accessibility. Therefore, it is judged that the preparation of the measures to improve the selection of lots in consideration of users, who use the primary medical services, is required.

This research empirically analyzed the selection factors and the locational selection factors of the medical service facilities according to the gradual increase of the importance of the selection factors and the locational selection factors regarding the establishments of the small- and medium-sized hospitals according to the rapid changes of the socio-economic conditions. By analyzing the priority order according to the levels of the importance of each evaluation item factor through a research related to the selection factors and the locational selection factors of the small- and medium-sized hospitals and by drawing what the important factors that have the influences on the competitiveness of the pre-existent small- and medium-sized hospitals are through the classification of the real estate locational factors and the non-locational factors, the purpose lies in utilizing them as the basic data and materials for the opening strategies of the small- and medium-sized hospitals considering the special, locational characteristics according to the important factors of the selection factors of the small- and medium-sized hospitals, regarding the medical suppliers that have been preparing, for opening the new, small- and medium-sized hospitals. Based on the results of the preceding researches and the researches on the case examples, 28 evaluation factors were arrived at in terms of the level of the medical treatment, the medical services, the accessibilities of the hospitals, the conveniences of the hospitals, and the physical environment. And, regarding the 28 detailed evaluation factors that had been collected, through the interviews with the related experts, the 5 factors of the medical level, the medical service, the expertise of the hospital, the convenience of the hospital, and the physical environment were selected as the upper class evaluation factors. And, according to each upper class, a total of 28 low-part evaluation factors were selected. Regarding the optimal evaluation factors that were selected, the optimal locational factors were selected by carrying out an AHP questionnaire survey investigation with 200 medical experts as the subjects. Regarding the AHP analysis results, similarly with the case examples of the precedent researches, the levels of the importance appeared in the order of the medical level, the medical services, the accessibility of the hospital, the physical environment, and the convenience. And the factors that were related to the facilities of a hospital appeared low. The results of this research can be applied in providing the basis for the decision-makings regarding the selections of the locations of the small- and medium-sized hospitals in the future.

Decision-making of the site for the medium and low-level radioactive-waste disposal facilities in 2005 can be estimated as a success. But the limits exposed during the process still remain as problems to be solved. Analyzing the causes of success and failure of the policy and their correlation was expected to provide an effective guideline on future policies. The analysis shows that the transparency of policy makers, the level of community supports and the public relations are decisive factors. System dynamics, a synthetic analyzing tool, is used as a methodology for policy analysis. The result of the system dynamics analysis shows that public confidence is to be the key role to for and against logics when transparency of stakeholder, subsidy and public information are set as adjustable parameters. Public confidence takes a role of leverage that can convert tendency of conclusion by the opinion which influenced by selected parameters.

This study has been performed to investigate group differences and determining factors of burnout of the workers in elderly living facilities. In this study, 131 male and female workers composed of social workers, health practitioners, and other management workers were selected among 23 retirement and nursing facilities in Korea between 2003 and 2005. They were asked about their socioeconomic background, working environment, and their perceptions on burnout in the working places. As for main dimensions of the burnout, there were three elements such as emotional weariness, diminishing personal accomplishment, and depersonalized behaviors. Particularly in this study, the depersonalized behaviors were defined as aggressive or rude verbal and behavioral outbursts from anger. As a result of this study, the following results were found: Most workers have medium level of perception on their commitment and burnout, but there. are some risk factors; newly married young workers were less satisfied or fairly rewarded with their job and as a result, they have significantly higher level of emotional weariness but lower feeling of personal accomplishments. In addition, they occasionality practiced aggressive or rude behaviors such as yelling, threatening, and physically harassing As for the influence of determining variables, long-time workers of long established facilities were more satisfied and less burnout. In addition, there are some impacts of job category; health practitioners were more burnout than social workers. In this study, suggestions are made as follows: first, guiding and settlement programs should be developed for the newly started young married workers, particularly at early stage of their career. Second, future aspects of facility visions should be guided for the workers, so that they are relieved from stressful routines without any future plan. Third, medical workers such as physical therapists and nurses should be further monitored for main reasons of increasing their stress.

The gate of university can be the first impression of the University itself and most important advertising structure which is more than just a structure that people pass by. It can also be the medium that connects the outside with the inside of the campus. Therefore, many universities are willing to have a unique and symbolic gate of their own. Recently, university representatives have become interested in arranging external areas of the campus. At this respect, studying and researching university gates and surroundings facilities must be realized. We visited 104 different universities gates to research and survey people about what they think of the internal and external individuality of each gate. According to these researches we established a full data base of 24 types of classifications, 5 characteristic forms of each shapes, 8 forms of the symbolic characteristics of university gates and 10 surroundings facilities of the university gates.
