        연안정비사업이 수행된 만성리 해수욕장에 대해 주기적으로 측량된 해빈자료와 2016년 제18호 태풍 차바 내습시 관측된 강력한 해빈 변형외력으로부터 해빈변화가 현장관측자료를 기반으로 기술되었다. 만성리 해수욕장의 해빈은 양빈 이후 3개월에 걸쳐 자연외력에 반응된 안정 화가 서서히 진행되었으나 태풍 차바에 의해 그 안정화가 깨어졌으며, 태풍내습 2개월 후부터 다시 안정적인 해빈을 나타내어 양빈 1년 후까지 큰 변화가 나타나지 않았다. 태풍 차바 내습직후 만성리 해수욕장의 해안선은 도류제가 설치된 부근해빈과 잠제의 영향이 없는 해빈북측에서 주 로 해안선이 후퇴하였고, 잠제배후역에서 해안선이 전진하였다. 또한 태풍내습직후 해빈체적이 3,395㎥ 감소하였는데, 감소한 영역은 주로 잠제의 영향이 없는 해빈북측에 집중되었으며 잠제배후의 후빈역은 오히려 퇴적되었다. 따라서 만성리 해수욕장에서 수행된 연안정비사업은 파랑에 기 인한 표사이동이 지배적인 이곳에서 해빈보존에 상당히 기여하였다.

        The tourism experience factor is an essential source of competitive advantage in the tourism industry and is an important factor for predicting future tourism behavior. Tourism experience elements can be composed of areas of education, entertainment, aesthetics and deviance (Pine and Gilmore, 1998). This study examines the effect of tourist experience factors on tourist loyalty and it is meaningful to see if the experiential economic theory of Pine and Gilmore (1999) is applicable. In order to achieve the purpose of this study, we conducted a questionnaire survey on tourists using experiential tourism factors. As a result, it was found that recreational experiential factors had a significant effect on memory. Memory has a significant effect on both visitor satisfaction and tourist loyalty. This study has academic significance because it focuses on the tourism experience factor which is the core of experiential economic theory. Practical significance is that a lot of experiential contents should be found in order to better match the tourist experience factor to the requirements of visitors to the tourist site. As a result, it is expected to generate revenue and improve its competitiveness.

        The objective of this study is to analyze the investment adequacy of the projects implemented according to the master plan on sewerage rehabilitation at Seoul. The planned and actually implemented ratio of invested money on sewage treatment plants (STPs) to sewers were compared in two temporal periods. Though the planned ratio of investment on STPs to sewers was 50:50 (in 2009-2020) , the actual implemented ratio in 2009-2013 was 34:66. Until 2020, the greater investment ratio on STPs to sewers should be made considering the necessity of coping with stricter legal compliance on advanced treatment, stormwater treatment and so on. The priority of the planned and partially implemented projects among four STPs and at each STP was evaluated. Considering only the performance indicator of reduced load of BOD, T-N, T-P per the capacity of each STP facility, the performance among four STPs was shown as Jung-Rang>Tan-Cheon>Seo-Nam>Nan-Ji. The reverse order of the performance results in the past may be considered for future investment priority, but the efficiency of operation implemented at each STP, deteriorated status of each STP, investment in the past and so forth should also be considered. As for the priority of projects conducted within each STP, projects related to legal compliance (such as advanced tertiary treatment, stormwater treatment, etc.) have highest priority. Odor-related project and inhabitant-friendly facility related projects (such as building park on STPs, etc.) has lower priority than water quality related projects but interactivity with end-users of sewerage should also be important.

        As sewerage systems have obsolete, as quality and service level standards increase, and as rain characteristics change, the sewerage utility authorities are challenged to develop cost recovery strategies that assure financial sustainability. In this study, we conducted scenario analysis to examine the effect of three alternatives of partial or full sewerage cost recovery in Seoul during 2014-30 periods. It turned out that the alternative 1 is optimal and recommended. According to alternative 1, we had better increase annually sewerage fee by 14.8% until 2020 and thereafter apply only the inflation rate in setting sewerage fee. It would gradually decrease the deficit after 2019. The accumulated deficit of 13 billion Won in 2030 was estimated.We expect that this kind of analysis may provide useful informations to help sewage utility staffs, decision makers, and regulatory authorities understand, develop and implement ultimate full cost recovery strategy for many municipalities.

        As sewer flooding frequents due to localized and concentrated stormwater and increased non-permeable surface area after urbanization, building cities with sound water recycle and accordingly efficient management of rainwater is demanded. To do this, the existing sewage (including rainwater) fee imposition system should be philosophically evaluated. This study presents problematic issues of the existing domestic sewage fee imposition system considering the principle of sharing costs on the service of sewage and rainwater collection and treatment. Four methods to improve the existing sewage fee imposition system are suggested: 1) imposing stormwater fee according to Polluter Pays Principle, 2) clarification of the share of public sector, 3) reducing or exempting the sewerage fee for inhabitants reducing urban runoff by constructing their own rainwater management facilities, 4) imposing charge for discharging rainwater to sewers due to new development action. Short, mid, or long term planning for rainwater management is recommended considering the situation of each municipality.

        월성원자력본부의 조밀건식저장시설인 MACSTOR/KN-400의 인허가 과정에서 사고조건에 대한 바스 켓의 안전성 평가를 위한 실증시험의 필요성이 제기되었다. 실증시험을 위한 낙하시험시설을 한국원자력 연구원에 설치하고 바스켓 낙하 실증시험을 수행하였다. 실증시험 결과 실린더 내 적재 바스켓의 상부 용 접부가 낙하 바스켓과 충돌하여 파손되고 누설이 발생하였다. 기존 바스켓이 실증시험에서 누설율 성능 요건을 만족하지 못함에 따라 바스켓의 설계 개선안 도출이 필요하게 되었다. 설계 개선을 위한 방향을 선정하고 이에 기초하여 6 종류의 설계 개선안을 도출하였다. 개별 설계 개선안에 대하여 구조해석 및 시편시험을 수행하였다. 구조해석 및 시편시험의 결과를 바탕으로 최종설계안을 확정하였다. 최종설계안은 바스켓의 중앙 포스트의 높이를 감소하여 낙하 바스켓과의 충돌속도를 감소시키는 설계안이었다. 최종설 계안에 대한 시험모델을 제작하여 낙하실증시험을 재수행한 결과 모든 성능요건을 만족하였다.
