Equipments that can transmit maritime distress signals in accordance to Global Maritime Distress Safety System are the followings: A1 water(Very High Frequency, SART), A2 water(MF/HF Radio Equipment), A3 water(INMARSAT), A4 water(Emergency Position Indicating Radio Beacon). Institutions with the capacity to receive distress signals are Korea Coast Guard affiliated radio stations, patrol ships, Rescue Coordination centers, Vessel Traffic centers, Complex problems regarding repetitive distress alarms, inaccurate statistics, multiple control towers are existent. Consequently, effective measurement to resolve dispersed operating maritime distress signal system are in time of need. Moreover, current KCG Headquarter is considering to integrate five distress radio stations dispersed across nation into a single international safety communication center. The integration of radio stations are efficient in terms of information coordination between nations, however, it cannot support efficient response to real-time maritime incident. Therefore, in this study, a new system that can rapidly response to real-time maritime incident will be proposed.

The construction of National Spatial Data Infrastructure (NSDI) started from 2008 and was completed at 2012, with the aim of co-utilizing public agencies' national spatial information by integrating and linking. Despite the existence of the NSDI, an update of spatial data is not fully reflected because the spatial information has not been updated simultaneously by NSDI and public agencies. By examining the public agencies' services using the spatial information, a national budget is wasted because the re-usable similar services are duplicated. These issues could be solved by adopting a cloud system, whose concept is co-utilizing IT resources, to the NSDI. This study examined the service cloud based expansion and development plan for NSDI. The plan included an implementation strategy for a spatial information service cloud system and an establishment plan for a governance system. The service scenarios, concept diagram, and service functions for the system were derived in a system implementation plan. For the service functions, the unit functions of two modules were proposed and specific functions were derived. In the establishment of a governance system, the business roles and business processes were defined for organizations managing service cloud based NSDI. The business role and process were defined and derived by each service life-cycle step. With the proposed system implementation plan, a detail system design and composition of the organization could be possible, and a service cloud-based NSDI system could be implemented.

Recently, natural and social disasters in Korea are increasing, and new disasters such as COVID 19 and sinkholes, and large-scale disasters that combine natural and social disasters are occurring frequently. In order to reduce damage caused by disasters and effectively respond to disasters, the importance of disaster safety education is emerging because it is necessary to understand the awareness of disaster situations and the functional response process. Ministry of Public Interior and Security is providing disaster safety education for emergency managers through 54 specialized disaster safety education institutions. There is also a lack of experience facilities. This has a problem in that it makes it difficult for disaster safety personnel to effectively respond to disasters due to lack of experience in actual disaster sites. Also, unlike other education fields, the connection between disaster safety education contents and new technologies such as AI is still lacking. In this study, focusing on natural disaster, the current status and problems of domestic disaster safety education institutions and their contents are investigated and analyzed, and based on this, this study suggested improvement plans for domestic disaster safety education contents such as establishment of a unified disaster safety standard curriculum, production and distribution of disaster safety education experience contents using virtual reality technology and infotainment technology, and development of mobile AI tutoring service.

The study explored how two elementary school teachers perceived computational thinking, reflected them into curriculum revision, and taught them in the classroom during longitudinal professional developed program (PDP) for nine months. Computational thinking is a new direction in educational policy-making including science education; therefore we planned to investigate participating teachers' perception of computational thinking to provide their fundamental understandings. Nine meetings, lasting about two hours each, were held with the participating teachers and they developed 11 lesson plans for one unit each, as they formed new understandings about computational thinking. Data were collected through PDP program while two teachers started perceiving computational thinking, revising their curriculum, and implementing it into their class for nine months. The results were as follows; first, elementary school teachers' perception of computational thinking was that the definition of scientific literacy as the purpose of science education was extended, i.e., it refers to scientific literacy to prepare students to be creative problem solvers. Second, STEAM (science, technology, engineering, arts, and mathematics) lessons were divided into two stages; concept formation stage where scientific thinking is emphasized, and concept application, where computational thinking is emphasized. Thirdly, computational thinking is a cognitive thinking process, and ICT (informational and communications technology) is a functional tool. Fourth, computational thinking components appear repeatedly and may not be sequential. Finally, STEAM education can be improved by utilizing computational thinking. Based on this study, we imply that STEAM education can be activated by computational thinking when teachers are equipped with competencies of understanding and implementing computational thinking within the systematic PDPs, which is very essential for newly policies.

In this study, we investigated and the following conclusions are presented by identifying the current status and problems in order to expand the future's value of the community care project introduced and implemented to improve the quality and care for the elderly's life. First, the needs analysis of the elderly receiving services is composed of patient-centered rather than investigator-centered, and in particular, medical management through medical staff visits should be strengthened, and specialized service items according to gender, age, disability type, and personal preference should be strengthened. This will have to be gradually strengthened. Second, by analyzing the satisfaction, redundancy, and effectiveness of service items, we save money, and consider the consumer-oriented service item composition and application of items necessary for new services. Third, through the introduction of an integrated schedule management system, it is necessary to specialize in pre-booking and visit schedule management between the elderly and the direct service organizations that provide services. Fourth, as an effort to solve the financial problem, it is necessary to prepare a rational resource sharing system with health and medical finance, long-term care insurance system, and social welfare financial project. and it may consider that putting the medical personnel who are from local public medical college input. Through these proposals, the community care business will be able to complete and have future value as a universal aged care system.

The purpose of this study was to understand the parents' perceptions of the distance learning provided to students with disabilities and to explore the demands for educational support. A survey was conducted on a total of 2,392 parents of school-age children with disabilities. The survey questions were largely divided into the learning support to prevent educational gap, support for behavioral and psychological difficulties, and care support for educational welfare. As a result of the study, it was found that face-to-face education in schools was the most important to prevent the educational gap between students with disabilities, and counseling on distance learning methods and strategies suitable for the characteristics of the disabled in connection with the Special Education Support Center was the most necessary. As a learning support method for distance learning for students with disabilities, there was a high demand for individual learning support through preparatory special education teachers, and it was necessary to secure enough learning aids and assistive technology devices to be used appropriately when needed. In addition, psychological counseling and educational support for students with disabilities were requested, and there were demands for development of care programs suitable for the characteristics of the disabled and assignment of dedicated personnel. Based on the results of this study, this study suggested implications for students with disabilities to bridge the learning gap and provide educational support due to distance learning.

지속가능한 국가 발전을 위한 물관리 정책은 항상 국정 과제의 중심에 있다. 물관리는 수재해예방, 양질의 안정된 물이용, 충분한 식량생산, 수생태계와 물환경의 보호, 효과적 재정투자 등과 같이 다양한 분야에 계층적이면서도 상호연계성 있는 전문성을 요구한다. 동시에 물관리의 효과와 편익은 경제활동의 기반이 되고 환경보전의 원천이므로 정책의 수요는 정부뿐만 아니라 국민과 더불어 자연으로부터 기인한다. 특히 기후변화의 불확실성 또는 감염병 대발생과 국가적 위기에도 지속가능한 국가 발전을 이행하기 위해서는 시의성 있고 유효한 물관리 정책은 필수이다. 그동안 우리나라 물관리 정책의 세분화 또는 파편화는 물관리 전문성 강화의 효과보다는 비효율성의 결과를 더 크게 생산해 왔었다. 특히 부족한 협력과 조정은 과잉·중복 투자, 비일관적 정책, 비효율적 성과라는 왜곡된 통합물관리 정책 순환이 반복되게 하였다. 최근 정부는 국토교통부의 하천수량(홍수 포함) 및 광역상수도 관리 기능을 환경부로 이관하는 물관리일원화를 추진하여 통합물관리의 발판을 마련하는 계기를 달성하였다. 하지만 비록 정부조직법 개정과 물관리기본법 제정으로 통합물관리 정책의 틀은 마련되었으나, 국토교통부가 하천법 상의 일부 사무를 담당하므로서 하천관리 정책의 복잡성과 다원화는 높아졌다. 따라서 하천의 이용 및 관리에 관한 만족도, 관리주체, 미래상, 물관리일원화 후 정책수요, 기후변화에 관한 인식, 하천관리 참여 의향 등을 조사하는 연구는 시급한 실정이며 향후 하천기본계획, 생태하천복원사업, 소하천정비사업 등과 같은 재정사업의 추진 방향에도 매우 중요한 주제라고 할 수 있다. 본 연구에서는 현재와 미래 하천의 이용 및 관리, 그리고 정책방향에 대하여 일반 시민(4,500명)과 전문가(168명) 대상의 설문조사를 실시하였으며 인식의 공통점과 차이를 비교분석하였다. 설문조사의 내용은 3가지 부문(하천이용, 하천관리, 하천정책)으로 구분하여 각 부문별로 세부문항으로 구성하였다. 일반 시민과 전문가 간의 인식조사 비교 결과, 공통적으로 시민과 전문가는 하천의 바람직한 미래상으로 '깨끗한 수질의 하천'을 가장 높게 선호하였다. 하천관리 우선순위를 묻는 질문에 대한 시민과 전문가의 응답도 대하천, 도랑이나 개울, 중하천, 소하천 순으로 동일하였지만, 1순위와 2순위의 격차는 시민(26.1%)보다 전문가(1.2%)가 낮았다. 또한 시민과 전문가는 하천관리의 주체로 '물전문기관'을 가장 높게 선호하였지만, 전문가는 '물전문기관' 다음으로 중앙부처(20.2%)를 선호하였지만, 시민은 중앙부처(6.8%)를 가장 선호하지 않는 하천관리 주체로 응답하여 두 집단 간의 큰 인식의 차이를 알 수 있었다. 물관리일원화 후 보다 큰 관심을 가져야할 정책으로는 '건강하고 깨끗한 수질'을 시민(38.9%)과 전문가(47.0%)는 1순위로 선택하였으나, 2순위는 시민은 '생태서식공간'(11.6%)을 전문가는 '안정적 수량확보'(20.2%)를 선택하여 두 집단의 인식 차이가 있음을 알 수 있었다.
