The purpose of this study is to analyze the patient's perception of cleanliness and safety, which are items in the hospital environment area of the patient experience evaluation. In the evaluation of patient experience, the hospital environment area has two items and occupies a small proportion of the total evaluation items. Unlike other items, which are specific items of interpersonal factors, despite the low specificity of the items, the evaluation results show large deviations. Therefore, it is an important item in evaluation. When asking whether the hospital environment was clean or safe, these two words have a problem of being abstract and ambiguous, so we conducted a questionnaire directly asking the patient's experience and presented the analysis results. As a result of the analysis, patients did not clearly distinguish between cleanliness and safety. Overall a clean environment was a safe environment, and a tendency to perceive a safe environment as a clean environment was confirmed. As a result of grouping similar variables and analyzing the correlation, cleanliness has the importance priority of cleaning > visitor management > environmental management > facility safety > eco-friendliness > ventilation, and safety has the importance priority of cleaning > environmental management > facility safety > visitor management > eco-friendliness > ventilation.

Chitosan을 피막을 형성하여 포자분산을 억제하는 새로운 사과 겹무늬썩음병 방제법의 피막재로 활용코져 연구하였다. Chitosan 필름과 polyvinylalcohol(PVA)을 혼합한 chitosan/PVA 혼합필름을 제조하고 인장강도, 신장률, 점도 등 물성을 검토하였다. Chitosan/PVA 혼합필름이 chitosan 단독 필름보다 우수한 피막형성능을 보였다. FT-IR spectra 분석결과 chitosan과 PVA간에는 새로운 화학결합 형성은 관찰되지 않았다. Chitosan과 chitosan/PVA 필름은 Botryosphaeria dothidea에 대한 상당한 항진균활성을 보였다. Chitosan과 chitosan/PVA 필름은 생분해성평가 공시균주들에 의하여 생분해성을 보인 반면 PVA 단독필름은 생분해성을 나타내지 않았다. 위의 각종 피막을 이용하여 과수원에서의 B. dothidea의 포자분산 억제효과를 측정한 결과, chitosan/PVA 혼합피막이 우수한 피막형성능과 피막지속성을 보였고, 포자분산 억제효과도 가장 우수하였으며, 1%의 chitosan과 5%의 PVA를 혼합한 피막의 경우 포자분산 억제률은 97.0%에 달하였다. The applicability of chitosan, a biodegradable natural polymer, as the coating material to prevent the dispersal of the spores of the apple white rot agent Botryosphaeria dothidea, was investigated. The physical properties of mixed chitosan/polyvinyl alcohol(PVA) film showed the increased physical properties for film formation, such as tensil strength, elongation, and viscosity, compare to either chitosan or PVA film. The FT-IR spectra of chitosan/PVA film indicated that the film was formed by simple blending not by any new synthetic bond. The chitosan and chitosan/PVA film showed effective antifungal activity on B. dothidea. The formed films were well decomposed by ASTM strains used for biodegradability test, on the other hand, the PVA film could not be decomposed by above standard strains. The field test at apple orchard showed that the dispersal of B. dothidea spores could be effectively reduced by coated film, especially by chitosan/PVA film. The spore dispersal was reduced upto 97.0% by 1.0% chitosan/5.0% PVA film during 4 months.

This study proposes cooperative governance as a means of solving problems in the existing pilot signboard improvement projects. The pilot signboard improvement projects executed in Korea have so far been led mainly by the government, and such a “government initiated” passive project process does not attract remarkable attention from the community. Even though the intention of signboard improvement is to vitalize the local community and create an aesthetic feature in city, it is used as a mere cursory administrative project, and it also causes civil complaints. This is because there are problems in the fundamental structure of the signboard improvement projects that have not been solved, which in turn causes a vicious circle rather than the lack of ability of the government that fails to settle the conflicts between various stake holders. As projects have been conducted without consensus, which is the most important factor, the intended beneficiaries of the projects are ambiguous. For this purpose, the study extracted and examined study literature dealing with urban environment improvement projects and looked at statistics and research of the pilot signboard improvement projects. And the necessity of governance was researched by examining the limitations of pilot improvement projects based on previous studies. The high effectiveness of the signboard improvement project led by residents was confirmed through analyzing the four cases extracted. Thus, this study paid attention to the need of cooperative governance as a means of solving problems in the existing pilot signboard improvement projects, and it proposed significant performance analysis data of existing signboard improvement projects in order to find ways for highly efficient community initiated signboard improvement projects to be incorporated into future pilot signboard improvement projects.
