A study on the public design rules of the government and each local government showed that the historical and cultural street landscape was included in the public design field, but it did not provide a clear evaluation index for the historical and cultural street public design. Against this background, this study intends to provide basic data for the improvement and improvement of the public design of the historical and cultural street in the future by producing an evaluation index for the public design of the historical and cultural street landscape. First, in this study, 6 evaluation indicators and 19 detailed items were derived by conducting expert Delphi survey twice on the basis of previous studies. Second, exploratory factor analysis and AHP analysis were conducted through a survey to verify the validity of the evaluation index and the priority of the index items, and as a result of the analysis, the Cronbach'α coefficient and the consistency ratio were verified. Among the evaluation indicators objectively derived through the above method, the priority was 'historical and culture-related> public-related> safety-related> accessibility-related> lasting-related> related to aesthetic harmony. The results of this study are meaningful in that they can provide basic data for the improvement and improvement of public design of historical and cultural streets in the future.

The appropriateness of introducing blockchain technology into food safety management systems was evaluated by conducting a survey of experts on the effectiveness and constraint evaluation indicators, and a portfolio analysis was conducted to set the priorities of blockchain application. The food safety management activities considered in this study were issuing documents on food import/export, food hygiene rating scheme, civil complaint management in the food sector, food- related certification, risk information management, and food traceability systems. The sectors that can be expected to be effective in the introduction of blockchain technology were food- related certification, food hygiene rating scheme, risk information management, and issuing documents on food import/export. In the case of food traceability systems and civil complaint management, the introduction of blockchain technology was not recommended due to ineffectiveness. From the evaluation of the constraints (e.g., technical limits, cost, legal amendment, personal information disclosure, timeliness, and ease of connection) to be overcome when introducing blockchain into food safety management, it was found that there are more than average constraints in all six areas. In particular, the food traceability system was evaluated to have the most constraints. Issuing documents on food import/export is very effective with the introduction of blockchain technology, but due to high cost and legal restrictions, it is necessary to improve the institutional system in order to introduce blockchain. Among the evaluation sectors, food- related certification, food hygiene rating scheme, and risk information management on foods were suitable for preferentially adopting blockchain technology since these areas might experience greatly improved reliability and transparency through the introduction of blockchain, with relatively low constraints.

최근 우리나라에서 발생한 홍수 중 많은 관심을 불러일으킨 2010년 광화문 일대와 2011년 강남역 일대 홍수의 주요 원인은 하천관리를 통하여 대응해온 지금까지의 홍수와는 달리 도시의 우수배제 기능이 높은 강도의 강우에 대응하지 못한 것으로 분석되고 있다. 도시내부에서 발생한 이 같은 홍수는 도시의 기능에 심각한 영향을 줄 수 있으며, 거주민의 안전과도 밀접하게 연관된다. 본 연구에서는 도시의 기능과 거주민의 안전을 우선적으로 고려한 홍수 취약성평가 인자를 선정하고자 한다. 기존의 여러 홍수취약성 연구들에서는 취약성을 평가함에 있어 피해금액을 기준으로 적용하는 경우가 많이 있다. 장기적인 홍수대응, 완화 정책의 구상에 있어 예상되는 피해금액은 중요한 지표라고 볼 수 있다. 그러나 이 방법으로는 도시에서 발생 가능한 피해를 모두 반영하는데 한계가 있다. 도로, 지하철, 철도 등의 교통수단이 침수되는 경우, 피해회복을 위한 비용뿐만 아니라, 도시기능에 심각한 영향을 주어 도시의 생산성, 안정성에 막대한 피해를 남길 수 있다. 따라서 피해금액의 규모에 대한 접근만으로는 도시에서 발생한 홍수에 의해 피해를 받는 취약요인을 적극적으로 반영할 수 없다. 본 연구에서는 도시홍수 피해양상과 이에 대한 대응 방법 등 홍수의 물리적 위험성 뿐 아니라 홍수와 연관된 사회적인 요인들을 반영한 취약성 평가인자를 구성하기위하여 인자간의 인과관계 등을 고려하여 인자의 범위를 규정하고 델파이 설문조사와 문헌 연구를 통하여 전문가 의견을 수집, 분석하였다. 홍수취약성에 영향을 주는 요인들을 크게 3가지 그룹으로 정리하여 도시구조물, 거주민, 위험요인으로 구분하고 각 항목별로 영향인자을 선정하였다. 결정된 인자는 2011년 홍수피해가 발생한 도림천 유역에 적용하여 홍수취약성 평가를 수행하고자 한다.

With respect to the quantity, quality and social value of forest jobs, we have developed three major criteria and 11 indicators for evaluating decent forest jobs. The importance and weighted value of the criteria and indicators were investigated through a survey which was conducted on 50 experts involved in Governmental Forest Job Committee, academic and different groups of communities. The 35 experts responded to the survey chose the 'job creation potential' as the most important criterion, and they recognized the 'job quality' has a relatively higher importance than the 'social contribution'. The survey results showed that 'political will' and 'job security' have the highest weighted values among indicators while 'wage level' has the lowest value. The developed criteria and indicators are able to be used as a means of evaluating degree of decent forest jobs for both new and existing jobs.

The desire for living without hazardous damages grows these days, the city strategy to make the safer community has become an issue. The global assessment for the flood index require the process considering different climate of the world cities. In this study, the actual rainfall observations of the world's major cities were collected. To compare different rainfall characteristics, we calculated some indicators such as frequency factor etc using the probable maximum precipitation. Using the results of these indicators, major cities in Korea show greater variability in the rainfall characteristics when compared to other major cities in the world. These results are expected to be useful for the development of global flood risk assessment as well as the setting the direction for future flood prevention measures.

확률론적 위험성 평가는 하중, 재료특성 등과 같은 불확실성 인자를 고려하여 구조물의 안전성을 평가하는 기법이지만 모든 불확실성을 고려하는 것은 현실적으로 불가능하다. 또한 원전 격납건물은 콘크리트, 철근, 라이너, 텐던이 복잡하게 결합되어 있다. 따라서 전역민감도 분석을 통해 격납건물의 불확실성 인자 검토하고 선정하는 작업은 필요하다. 따라서 본 연구는 대리모델을 기반으로 축소규모 원전 격납건물의 전역 민감도 분석을 수행하고 격납건물의 주요 영향인자를 분석하고자 한다. 유한요소 해석 모델을 기반으로 대리모델의 학습데이터를 생성하였으며 구축된 대리모델의 성능지표를 분석하였을 때 높은 회귀성능을 갖는 것으로 판단된다. 대리모델을 기반으로 전역 민감도 분석을 수행한 결과 콘크리트의 인장균열이 발생하는 내압수준에서 민감도 지수는 콘크리트의 압축강도가 높지만, 전체적인 내압 구간에서 민감도 지수는 텐던의 탄성계수 및 항복강도가 높은 것으로 나타났다.
