This study was performed to develop a children’s dietary life safety index required by the Special Act on Safety Management of Children’s Dietary Life enacted in 2009. An analytical hierarchy process was used to obtain initial weights of dietary life safety evaluation indicators. The Delphi method was applied to develop the weights along with 98 food and nutrition professionals. Three representative policy indicators, nine strategy indicators, 11 main evaluation indicators, and 20 detailed evaluation indicators were selected for the children’s dietary life safety assessment. Three policy indicators and nine strategy indicators were the following: children’s food safety indicator (support level of children’ safety, safety management level of children’s favorite foods, and safety management level of institutional food service), children’s nutrition safety indicator (management level of missing meals and obesity, nutrition management level of children’s favorite foods, and nutrition management level of institutional food service), and children’s perception and practice level indicator (“Dietary Life Law” perception level, perception, and practice level for dietary life safety management, perception, and practice level for nutrition management). Weights of 40%, 40%, and 20% were given for the three representative policy indicators. The relative importance of nine strategic indicators, which were determined by the Delphi method is as follows: For children’s food safety, support level of children’s safety, safety management level of children’s favorite foods, and safety management level of institutional food service were given weights of 12%, 9%, and 19%, respectively. For children’s nutrition safety, the missing meals and obesity management level, nutrition management level of children’s favorite foods, and the nutrition management level of institutional food service were given weights of 13%, 11%, and 16%, respectively. The “Dietary Life Law” perception level, perception and practice level of dietary life safety management, and perception and practice level of nutrition management were given weights of 4%, 7%, and 9%, respectively.

본 연구는 autonomous vehicle(AV)의 운전능력을 평가하기 위해 operation design domain (ODD)의 특성을 고려한 적정 평가지표를 도출하고 평가 중요도 우선순위를 도출하였다. 교차로, 불법주정차, 버스 정류장, 자전거 도로 및 mid-block 횡단보도 등에 해당하는 ODD를 교통 시뮬레이션 환경에 구축하였으며, 실제 AV 주행 데이터 분석을 통해 시뮬레이션 환경에서 차량 거동을 구현하였다. 종방향 평가지표와 차량간 상호작용 평가지표를 활용하여 주행안전성 분석을 수행하였으며, 분석 결과를 기반으로 ODD별 요인분석을 통한 적정 평가지표를 도출하였다. 본 연구에서 도출한 적정 평가지표는 ODD별 AV의 운전능력을 평가하는데 있어 중요하게 작용된다. 특히, 교차로 유형과 관계된 ODD의 경우 속도의 변화량과 관계된 평가지표가 AV의 운전능력 평가에 효과적인 것으로 확인되었다. 불법주정차, 버스정류장과 같이 다른 차량으로 인해 AV가 정상적인 주행을 방해받는 구간의 경우, 차두시간과 차간거리와 같은 차량간 상호작용 측면의 평가지표가 AV의 운전능력을 평가하는데 적합한 평가지표로 도출되었다. 추가로 본 연구에서는 도출된 운전능력 평가지표를 활용하여 ODD의 평가 중요도 우선순위를 결정하였다. 교차로 횡단보도, 불법주정차, mid-block 횡단보도 ODD가 높은 평가 우선순위로 도출되었으며, 교차로 및 mid-block 횡단보도의 경우 보행자와의 상충이 빈번하게 발생하는 구간인 것에 영향을 받은 결과로 판단된다. 본 연구의 결과는 향후 AV의 운전능력 평가 방법론 개발에 중요한 기준을 제공하며, 교통 안전 및 관련 정책 결정에 있어 중요한 기초자료로 활용될 것으로 기대된다. This study derived effective driving behavior indicators to assess the driving performance of autonomous vehicles (AV). A variety of operation design domains (ODD) in urban road networks, which include intersections, illegal parking, bus stop, bicycle lanes, and pedestrian crossings, were taken into consideration in traffic simulation analyses. Both longitudinal and lateral driving indicators were investigated to identify the driving performance of AVs in terms of traffic safety in mixed traffic stream based on simulation experiments. With regard to ODDs related to intersection types, it was found that indicators based on vehicles speed is useful for the evaluation. On the other hand, spacing and headway representing the vehicle interactions were found to be effective in identifying the deterioration of driving safety of AV in situations where AV maneuvering was disturbed by illegal parking and bus stops. In addition, this study prioritized the importance of ODDs based on derived evaluation indicators. The results of this study would be valuable in establishing a guideline for driving performance evaluation of AVs.

김도우 한국셉테드학회 2021 한국셉테드학회지 Vol.12 No.3

Despite the need to generate new indicators according to changes in crime phenomena and policies, the existing crime prevention performance indicators have not improved and are showing limitations. Therefore, the purpose of this study is to develop objective and systematic crime prevention performance indicators, focusing on exploratory research on crime prevention performance indicators. To this end, while reviewing the previously discussed domestic and foreign performance indicators, a comprehensive indicator system was investigated that can easily represent the changing crime phenomena and crime prevention performance. This study proposes performance indicators consisting of a total of 17 performance indicators (6 sincerity indicators and 11 quantitative indicators) in 7 areas, including crime prevention, report reception and response by the police, community security activities, internal capabilities, crime prevention diagnosis, crime reduction, and public safety. Through this, long-term and practical activity-oriented evaluation can be conducted. In addition, effectiveness is secured by using daily crime prevention activities as a quantitative indicator of prevention activities, and evidence can be provided to provide the most reasonable policy alternatives by utilizing limited resources from an environmental criminal perspective in the future.
