General replacement policy includes document-based LRU or LFU technique and other various replacement policies are used to replace the documents within cache effectively. But, these replacement policies function only with regard to the time and frequency of document request, not considering the popularity of each web site. In this paper, we present the document replacement policies with regard to the popularity of each web site, which are suitable for modern network environments to enhance the hit-ratio and efficiently manage the contents of cache by effectively replacing documents on intermittent requests by new ones.

The research tried to realize the policy which serves Innovation ability for culture-contents producer, and culture-contents producer's Innovation ability which impacts OSMU of contents in the policies of government for vitalizations of culture-contents industry. As a result, we have reached the conclusion that the supportive policies for technology, exports and marketing were effective to strengthen the innovation ability of management of human resource, creation and production area. Also we have found that content's OSMU has been influenced by innovation ability. The implication of this study are followed. First, the policies which are intended to revitalize the culture content industry by government has the effect that are some different ones from the settlement and intention. Second, the production industry of animation do still passive and closed organization management, without the efforts for opened and cooperative management. Therefore, the efforts of government which are more practical and realistic supports to revitalize and based on strategic cooperation of industry.

이 연구는 교육정책의 반복적인 정책실패에도 불구하고 이와 같은 현상을 규명하려는 학술적 노력이 부족했다는 문제의식에서 정책학습이라는 관점에서 교육정책의 변화 내용을 분석하였다. 이를 위해 정책이 수립된 지 20여 년이 넘었지만, 여전히 정부와 교원단체 간에 갈등이 심각한 교원성과급 정책을 정책 분석사례로 삼아 분석하였다. 분석결과, 첫째 교원성과급 정책은 김대중 정부에서 문재인 정부에 이르기까지 총 11차에 걸친 정책 내용의 변화가 있었다. 정부가 새롭게 출범할 때마다 교원성과급 정책은 내용에 변화가 생겼을 뿐만 아니라, 동일 정부 시기 동안에도 정책변화는 지속되었다. 둘째, 각 정부별 정책 내용의 변화 단계에서 어떠한 정책학습이 있었는지를 분석하였을 때, 대부분 '정치적 정책학습'과 '도구적 정책학습'이 이루어졌다. 즉, 정책의 목표나 가치에 대한 근본적인 논의보다는 교원성과급 정책의 옹호를 위해 차등지급의 비율을 조정하는 정책학습을 이어왔다. 이와 같은 현 상황을 회복하기 위해 이 연구는 교원성과급 정책의 기본적인 가치와 전략을 검토하는 '사회적 정책학습'을 통해 경직된 교직 사회를 변화시킬 수 있는 대안적인 정책 제시가 필요함을 제안한다.

Information Centric Networking (ICN) has recently attracted great attention. It names the content decoupling from the location and introduces network caching, making the content to be cached anywhere within the network. The benefits of such design are obvious, however, many challenges still need to be solved. Among them, the local caching policy is widely discussed and it can be further divided into two parts, namely the cache permission policy and the cache replacement policy. The former is used to decide whether an incoming content should be cached while the latter is used to evict a cached content if required. The Internet is a user-oriented network and popular contents always have much more requests than unpopular ones. Caching such popular contents closer to the user's location can improve the network performance, and consequently, the local caching policy is required to identify popular contents. However, considering the line speed requirement of ICN routers, the local caching policy whose complexity is larger than O(1) cannot be applied. In terms of the replacement policy, Least Recently Used (LRU) is selected as the default one for ICN because of its low complexity, although its ability to identify the popular content is poor. Hence, the identification of popular contents should be completed by the cache permission policy. In this paper, a cache permission policy called Cache-Filter, whose complexity is O(1), is proposed, aiming to store popular contents closer to users. Cache-Filter takes the content popularity into account and achieves the goal through the collaboration of on-path nodes. Extensive simulations are conducted to evaluate the performance of Cache-Filter. Leave Copy Down (LCD), Move Copy Down (MCD), Betw, ProbCache, ProbCache⁺, Prob(p) and Probabilistic Caching with Secondary List (PCSL) are also implemented for comparison. The results show that Cache-Filter performs well. For example, in terms of the distance to access to contents, compared with Leave Copy Everywhere (LCE) used by Named Data Networking (NDN) as the permission policy, Cache-Filter saves over 17% number of hops.

본 연구는 장애학생들의 스마트교육 활성화를 위해 특수교사 관점에서 장애학생들의 스마트교육 활성화 정책을 도출하고 도출한 정책을 기반으로 AHP방법론을 통해 중요도 측면에서 가중치를 분석하였다. 특수교사들이 생각하는 중요한 정책은 스마트교육 콘텐츠 개발, 교수 학습, 스마트교육 네트워크 확보지원, 법률적 기반 마련, 인프라지원 순이었으며 장애학생들을 위한 실질적인 교육 콘텐츠 개발 및 교수 학습 지원 정책이 상대적으로 중요하며 장애학생들을 위한 스마트 콘텐츠 개발 활성화 및 보급 관점에서 스마트교육 정책이 시행되어야 하는 것으로 나타났다.

This Present study examines the Japanese Tourist basic law, its background as well as the formation process. Furthermore, this article also investigates the contents of the tourist basic law. In addition, I intend to accomplish a comparative study between a tourist policy enacted by the tourist policy council in 1995 years and the policy enacted in the 1960ㆍ70s. As the purpose of the study is concerned, the question related to a recomposition of contents of the Japanese tourist basic law in the 21st century is considered.

지방자치제도가 활성화되고 있는 시점에서 지역주민은 지방자치단체 행정의 집행에 있어서 수동적인 객체가 아니라 행정서비스를 평가하고 능동적으로 구매하는 고객으로 인식되고 있다. 본 연구에서는 지역주민을 대상으로 하여 복지정책, 산업정책, 교육문화정책, 생활환경정책 등 다양한 분야별 정책콘텐츠에 대한 만족도를 측정하여 분석하고자 한다. 분석결과 보건복지정책, 교육문화정책콘텐츠를 제외한 나머지 분야에 대해서는 만족도가 낮은 것으로 나타났다. 이러한 결과를 바탕으로 정책적 제언을 제시하고 있다.

The purpose of this study is to analyze and assess the family policy of the Lee administration and to suggest agendas for sustainable future family policy. Traditionally, families are a unique unit of production and reproduction of family members and social laborers. In addition, families are the social safety net help people survive in a society. Therefore, family policies play an important role in contemporary society. In this context, we review the literature related to family and social policy, and the contents of Ministry for Health, Welfare and Family Affairs, which is the main authority in Korea. The results are as follow: Firstly, the Lee administration ignored the data showing that family policy should be a unique policy, and not a sub-division of welfare policy. Secondly, there is no difference between the active welfare policy of the Lee administration and policies of past administrations. Finally, this study suggests that subjects of future oriented family policy should focus on co-developing programs for the individual, family, and society, to develop problem-prevention and family needs- ordered policy, and to make integrated family policy through laws and delivery systems such as Healthy Family Centers.

Adolescent media addiction has emerged as an important social agenda in Korea. However, there has not been enough discussion on the causal structure of media addiction and policy interventions. The objective of this study is to identify and assess the mechanism of the existing and the revised Shutdown policy based on the systems thinking approach. To achieve this purpose, we establish the relationship between media usage, flow, and addiction, and develop a causal loop diagram. Based on the causal loop diagram, we explore the causal structure of two policy scenarios: shutdown policy and deregulation. Our study suggests that policy interventions inducing direct parental control on children's media usage time are ineffective since the time control reduces children's autonomy, which helps alleviate media addiction. Therefore, this study suggests that policy intervention should focus on alleviating addiction itself rather than on controlling media usage time.
