범죄예방을 위한 셉테드의 제도화, 자치경찰제도의 시행, 지역주민 주도의환경개선 사업 확대 등 사회적 환경의 변화에 따라 경찰, 자치단체, 기업체, 지역주민의 범죄예방에 대한 관심과 인식의 확대를 위한 교육기회가 필요한시점이다. 본 연구의 목적은 대상별, 수준별 셉테드 표준 교육프로그램 개발을 통해셉테드에 대한 사회적 인식확산에 기여하고자 한다. 본 연구에서는 셉테드 교육에 관한 국내·외 현황 검토와 연구진 브레인스토밍과 전문가 자문 등을 통해 셉테드 교육프로그램의 구성과 운영에 관한교육모형을 개발하고, 대상별, 기간별, 수준별로 표준화된 교육주제, 교육기간, 교과목 편성안을 제안하였다. Despite the fact that permanent and non-permanent education to spread awareness and strengthen professionalism of CPTED, standardized education programs by education target and level do not exist. In particular, it is necessary to strengthen the capabilities of the police, local governments, businesses, and local residents in order to institutionalize CPTED to prevent crime, implement the autonomous police system, and expand local residents-led environmental improvement projects. Considering that the target of CPTED education is adults, this study derived educational design methods based on adult learning theory. Based on the analysis of domestic and international CPTED education programs, education subjects were selected by subject and level. In addition, it was proposed that the selected subjects could be organized into actual education programs and used in educational sites. Through these education programs, it is expected that it will be possible to expand social understanding of CPTED by encouraging citizens interest in and participation in community safety and providing accurate CPTED knowledge and strategies such as CPTED s concepts and strategies.
범죄예방진단팀(CPO)의 역량 제고를 위한 CPTED 교육훈련 프로그램 개선방안

2017년 ‘공동체치안’이 국정과제로 선정되어 각 경찰서 소속 범죄예방진단 팀(CPO)이 그 업무를 전담수행 중이나, 진단팀 육성을 위한 체계적인 역량 평가 기준과 이를 기초로 한 교육프로그램은 제대로 마련되어 있지 못한 실정이다. 국정과제의 성공적 수행을 위해서는, 범죄예방진단팀이 개개인의 역 량(competency) 수준에 대해 평가받고, 자기계발ㆍ교육 등의 목표ㆍ방향에 대해 명확히 인식함으로써 각 지역사회의 범죄예방전문가로서 자리매김이 필 요한 실정이다. 이에 따라 이 연구는 외국사례 고찰과 DACUM(Developing a Curriculum) 분석을 통해 확인된 CPO의 책무 및 과업에 따른 교육과정 개선 안과 업무담당자의 자격인증체계를 제시하였다. 국제셉테드협회, 영국, 미국, 캐나다의 사례를 비교분석한 결과 CPTED담당자는 자격인증을 받기 위해 1단 계(기초) 및/또는 2단계(고급) 교육과정을 성공적으로 이수해야 하고, 일부는 필기시험을 통과해야 한다. 또한 교육수료 전ㆍ후로 일정 기간 동안의 실무경험을 쌓고 그 경력에 대하여 심사받음으로써 그 자격인증을 취득하고 있다. 또한 DACUM기법을 통해 도출한 CPO의 주요 책무는 범죄취약지역 방범환경 진단·평가, 침입범죄 피해 시설물 진단ㆍ개선, 유관 기관ㆍ부서ㆍ단체와 협업, 범죄예방/치안강화구역 지정ㆍ관리 등 10개로 나타났다. 이를 통해 제시한 CPO 교육과정 개선안은 이론 중심의 사이버학습, 초보 수준의 실습이 포 함된 기초과정, 높은 수준의 실습과 토론이 포함된 심화과정으로 구성하여 교 육과정의 효율성을 제고하고자 하였다. CPO의 고도화된 명칭으로서 CPTED 전문관 자격인증제를 도입하기 위해서는 앞으로 자격인증분야를 크게 ①방범 환경진단 및 분석 분야와 ②방범환경인증(우수시설인증 및 제품성능인증), ③ 방범환경조성기관 협업 분야로 크게 3개로 구분하고 ‘CPTED전문관 운영규칙’ 등의 명칭으로 경찰청 훈령을 제정하여 근무경력 심사, 특별교육과정 이수, 필기시험, 관련 마일리지 충족 등의 절차를 거쳐서 자격인증을 받도록 하는 안을 제시하였다. While the CPO (Crime Prevention Officer) is in charge of carrying out CPTED and community-oriented police service as the Community Policing Plan was selected as the central government project in 2017, the standards for systematic evaluation of job competency to foster the CPO team and the training & education programs based on it have not been properly prepared. In order to successfully carry out the national project, the CPO needs to be evaluated on the level of individual competence and clearly recognize the goals and directions of self-development and education, thus establishing itself as a crime prevention expert in each community. Therefore, the study considered DACUM techniques and foreign cases to further clarify responsibilities, scope and content of tasks through CPO analysis and to derive appropriate training and qualification programs in accordance with job competency, namely, knowledge and skills, which are required for tasks. In foreign cases, training and qualification programs were analyzed centering on ICCP of ICA, British DOCO, Canada Ontario’s CCP, NICP’s CPD and Florida FCP. The study presented a plan to improve the curriculum according to the CPO s responsibilities and tasks identified through foreign case studies and DACUM analysis, and a system for certification of qualifications of the person in charge. A comparative analysis of the cases of the International CPTED, the UK, the United States and Canada shows that personnel in charge of CPTED must successfully complete the first (basic) and/or second (advanced) curriculum in order to obtain certification, and some must pass written tests. In addition, CPOs obtain a certificate of qualification by accumulating working experience for a certain period before and after the completion of education and being reviewed for its experience. In addition, the CPO s main tasks, derived through the DACUM technique, were found to be ten: diagnosing and assessing the environment for crime prevention in crime-prone areas; diagnosing and improving facilities for damage from burglaries; collaborating with related agencies and organizations, and designating and managing crime prevention/treatment areas, to name a few. The CPO curriculum improvement plan was designed to enhance the effectiveness of the curriculum by organizing it into a theoretical-focused cyber-learning course, a basic course with novice-level practice, and an in-depth course with high-level practice and discussion. In order to introduce CPTED professional qualification certification system as an enhanced name for CPO, the qualification certification area will be divided into three areas, the first area for environmental diagnosis and analysis, the second area for environmental awareness (certification of superior facilities and product performance), and the third area for cooperation between relevant organizations for safety improvement, and the police will conduct a special examination, completion of the relevant process, including a written examination, and a mileage process.
전기자동차용 유·무선 통합 충전을 고려한 무선 충전 시스템의 두 가지 제어 방식에 따른 효율 비교·분석
허훈,이주아,심동현,손원진,이병국,Heo, Hun,Lee, Ju-A,Sim, Dong-Hyun,Son, Won-Jin,Lee, Byoung-Kuk 전력전자학회 2022 전력전자학회지 Vol.27 No.3
The charging methods of electric vehicles are divided into wired charging and wireless charging. Restrictions on the use of charging infrastructure for wireless charging vehicles currently exist because most charging infrastructure uses the wired charging method. Thus, wired and wireless integrated charging system has been studied. In this system, a wireless charging system especially requires a control method for high-efficiency operation in consideration of a change in a coupling coefficient. Therefore, this paper introduces two control methods for the high-efficiency operation of wireless charging that can be applied to wired and wireless integrated charging systems. In addition, loss analysis is performed through PSIM simulation to select a more advantageous method for high-efficiency operation among the two control methods. To verify the simulation-based loss analysis result, the two control methods are applied to the actual wireless charging system, and the efficiency is compared through the experiments Based on the experimental results, a control method suitable for high-efficiency operation of the wireless charging method is selected.

This paper proposes a method to adjust the turn ratio of a transformer for the high-efficiency operation of an LLC converter with a wide input range in a wired/wireless integrated charging system for electric vehicles. The characteristics of the inductive power transfer converter in the integrated charging system are analyzed to design the LLC converter, and the DC-link voltage range is derived. The aspect of voltage gain following each parameter of the LLC converter is analyzed, and the resonant network and transformer are designed. Based on the designed parameters, the feasibility of the design and control method is verified by implementing the operation of the LLC converter according to the DC-link and battery voltages.
