본 연구는 무용예술인의 진로계발를 위하여 우선적으로 추진하여야 할 정책 요소들을 추출하고, 요소별 정책추진의 상대적 중요도 및 우선순위를 분석하는데 목적이 있다. 이를 위하여 정부기관 및 유관단체, 학계, 무용예술인 등 3개 영역에서 선정된 전문가 25명을 대상으로 델파이조사를 실시한 결과, 3개 정책 영역, 14개 정책요소, 그리고 39개 세부정책으로 구성된 진로계발정책을 개발하였다. 무용예술인의 진로계발 정책 요소의 가중치는 '무용조직 및 지원체제 강화'가 28.5%로 가장 높게 나타나 이 항목이 다른 정책요소에 비하여 상대으로 중요하다고 인식하는 것으로 나타났으며, 다음으로 '무용재정 확대'(12.0%)와 '무용전문인력 양성'(12.0%), '교수-학습 환경 개선'(11.0%), '무용교육 제도화'(10.2%) 등의 순으로 나타났다.

원격 진료 또는 원격 강의와 같은 신뢰적인 멀티캐스트 다자간 통신에서는 멀티캐스트 기능 뿐 만 아니라, 모든 수신자에게 신뢰적인 정보 전들을 요구한다. 이를 위해, 네트워크 자원을 효과적으로 이용하고, 재전송 데이터의 전달 시간 단축, 그리고 그룹 멤버의 가입/이탈 시의 손쉬운 멤버쉽 관리를 위해서는 멀티캐스트 트리를 구성해야 한다. 본 논문에서 제안한 멀티캐스트 구성 알고리즘은 송신자가 수신자에 의해 전송되는 ICMP 메시지의 학장을 이용하여 송신자로부터 수신자까지의 경로를 계산하고, 그 경로에 따라서 최소 비용 멀티캐스트 트리를 구성하는 방법이다. 본 알고리즘은 다른 계층의 프로토콜과는 독립적으로 동작할 수 있고, ICMP 메시지 확장뿐만 아니라, IP 옵션의 확장을 통해서도 제공될 수 있다. 본 논문에서는 최근 인터넷 표준 초안으로 제안된 ICMP 메시지 확장을 기반으로 기술하였다. 본 알고리즘을 통해 적정한 재정 재전송자와 재전송 도메인이 구성되는 것을 간단한 프로그래밍을 통해 확인 할 수 있었다.

본 논문에서는 대규모 평시 또는 감염병 발생이전 지자체별 취약성 평가를 통해 감염병 발생 및 확산에 영향을 미치는 취약지표를 평가해보는 것이다. 이를 위해 국내 코로나19 대처사항(각종 회의자료 및 보고자료 등), 선행연구 등을 기반으로 확산취약시설, 감염취약계층, 사회적 취약여건, 대응능력(보건·의료/재정적, 사회적 대응역량) 총 4개의 증감유형으로 분류한 후 세부 평가지표로 약 24개로 세부지표를 선정하였다. 이러한 취약성 평가 결과는 지자체별 특성에 맞는 감염병 대응정책 수립에 필요한 근거자료를 마련하는 기초자료로 활용 가능할 것이다.

How do Korean people recognize major welfare policies of the Moon Jae-in government? Using a survey of 1,000 adults conducted in December 2018, this study examines what the public thinks about major issues related to welfare policies and what factors are related to variations in their opinions regarding the welfare policies. Results show that the public recognized the roles of government in providing welfare in a positive way. The positive opinion on expanding the coverage of National Health Insurance was the highest. Regarding the resolutions of fiscal problems of the National Pension Plan, there were substantial oppositions to reforms such as insurance premium increase, benefits cut, and increase in the age of receipt of pension benefits. Both efficiency and equality were perceived as important when government makes decision for allocating budgets. Only one-third of respondents agreed Korean government contributed to promoting the happiness of Korean people. Based on these findings, implications for developing welfare policies were discussed.

현대는 고도 정보화사회(information society)로서 DB의 가치는 점점 증가하고 전반적인 DB 서비스는 일반적으로 많이 발전하여 우수한 정보 서비스가 제공되고 있다. 그러나 관광정보 DB서비스의 가치는 아직까지 거의 인식되지 않고 있는 실정이다. 따라서 본 연구에서는 초보단계에 있는 관광정보 DB서비스의 만족도를 측정함으로써 국내 관광정보 DB서비스의 수준을 파악하고 관광정보제공자에게 개선해야 될 문제점을 제시하고자 한다. 그러므로 관광정보 DB서비스의 개념을 정립하고 관광정보 DB서비스의 현황을 고찰하고자 Bailey와 Pearson의 연구에서 제시한 39가지 요인 중에서 관광정보 DB서비스와 관련된 요인을 추출하고 의미를 재정의하여 HiTEL의 이용자를 대상으로 첫째, 정보서비스의 메뉴별 선호도 둘째, 관광정보 DB서비스의 만족도 셋째, 관광정보 DB서비스의 각 메뉴별 선호도와 만족도 넷째, 이용자 특성별로 각 메뉴의 선호도를 비교분석 다섯째, 관광정보 DB서비스의 만족요인을 분석하였다. 관광정보 DB서비스의 전반적인 만족도는 평균치(4.0)보다 저조한 3.85로서 저조하게 나타나고 있다. 즉, 관광정보의 이해도(4.55)는 평균보다 다소 좋은 반면, 다른 관광정보의 만족도는 평균치 보다 저조하다. 특히 관광정보의 연결사정(3.68)과 관광정보의 제공속도(3.44)가 아주 낮게 나타났다. 한편 HiTEL이 제공하는 관광정보 DB서비스의 각 메뉴 중에서 가장 자주 이용되는 메뉴는 알림나라(40.2%)이며, 아시아나항공(22.5%), 농협일렉트로뱅크(13.7%), 대한항공(9.8%), 위너스 OK서비스(6.9%), MEET/매경SCOUT(6.9%)의 순으로 관광정보는 전반적으로 골고루 이용되고 있다. 또한, 메뉴별 관광정보 DB서비스의 만족도가 평균만족도보다 낮은 것은 알림나라(3.48), 농협일렉트로뱅크(3.84), 대한항공(3.90), 위너스OK서비스(3.95)로 나타났다. 그리고 각 메뉴별 이용자의 계층별 선호도는 첫째, 남성은 알림나라(40%), 아시아나 항공(23.16%), 농협일렉트로뱅크(12.63%)를 많이 이용하나, 여성은 알림나라(42.86%), 농협일렉트로뱅크(28.57%)를 주로 선호하는 것으로 나타났다. 둘째, 연령별 선호도는 나이가 많을수록 단순 관광안내정보인 알림나라, 농협일렉트로뱅크보다는 보다 항공관련 정보를 더욱 선호하는 것으로 나타났다. 셋째, 직업별 선호도는 학생과 사무직에 종사하는 사람이 가장 많은 메뉴를 이용하며, 전문직, 관리직, 기술직은 대체적으로 항공관련정보를 더 선호하는 것으로 분석되었다. 넷째, 학력별 선호도는 고학력자일수록 많은 메뉴를 이용하고 있으며, 다섯째, 가입시기별 선호도는 가입한 시간이 길어짐에 따라 항공관련정보를 선호하는 것으로 나타났다.

With the development of information technology, the size of the system has become larger and diversified, and the existing role-based access control has faced limitations. Blockchain technology is being used in various fields by presenting new solutions to existing security vulnerabilities. This paper suggests efficient role-based access control in a blockchain where the required gas and processing time vary depending on the access frequency and capacity of the storage. The proposed method redefines the role of reusable units, introduces a hierarchical structure that can efficiently reflect dynamic states to enhance efficiency and scalability, and includes user-centered authentication functions to enable cryptocurrency linkage. The proposed model was theoretically verified using Markov chain, implemented in Ethereum private network, and compared experiments on representative functions were conducted to verify the time and gas efficiency required for user addition and transaction registration. Based on this in the future, structural expansion and experiments are required in consideration of exception situations.

It is not surprising to hear news about irresistible natural disasters all over the world due to climate change. Korean Government has focused on developing a variety of green technologies to reduce green house gasses, in particular, carbon dioxide. This study suggested 18 technology divisions for achieving green highway technology development in six different sub-sectors considering life-cycle of roadway and surveyed 29 highway and/or transportation professionals of three institutes using AHP(Analytical Hierarchy Process) analysis to construct "Green Highway"and realize carbon emission reductions and energy use efficiency in a road sector in Korea. Expert Choice Software was used to rank 18 technology divisions weighted by two-level choices. Transport Operating Infrastructure Improvement, Roadway Policy Implementation, Green Transportation(such as Pedestrian and Bicycle) were highly ranked by respondents according to results of the AHP modeling. Among the 18 divisions, technology policy for supporting R&D investments from development to commercialization was ranked as the most significant one to be focused. Green Transportation Facility Design/Construction/Operation and Eco-Friendly Roadway Plan were followed as expected since professionals have thought that the planning/design step of the life-cycle is a starting point to reduce carbon dioxide from roads more and more. Additionally, comparing the results with the Government investment trend 2006-2011 for the roads, it can be interpreted that the Government should invest to the R&D area more widely than before to promote element and core technology development for Green Highway Construction. Above all, small and mid-sized businesses have to be invested as well as encouraged to undertake green highwayrelated objects to accomplish the divisions which ranked high.

The purpose of this study was to examine the current status of the Dream Start program from the perspective of social investment strategy, and as well as to suggest future directions. The program has become a major government welfare program in korea since it was introduced in 2007 as a demonstration project, following research evidence and a sound rationale about the extensive success of Head Start in the U.S. and Sure Start Programme in the UK. The aim of Dream Start is to provide integrated services for the vulnerable children, aged 0 to 12, and their families who are identified using a national administration data record of disadvantaged families with children. In order to promote the vulnerable child's well-being, to overcome inequalities, and to give every child the best start in life, Dream Start adopted a local, "whole family" approach. Case management services form an essential part of the Dream Start to customize and integrate comprehensive services such as counseling, health care, parenting advice and education, academic tutoring, and after-school activities. Although there has been a general improvement in key factors since its inception, Dream Start has not yet sufficiently shown the strong and hoped-for impact. In the meantime, Dream Start must be given financial expansion and extensive policy supports to get the chance of realizing and evaluating long-term gains for children and their families. More work need to be done to overcome inequalities and to make Dream Start service more accessible for the most disadvantaged families with children in Korea. Practical and policy suggestions for future directions of the Dream Start programs were discussed.
