최근 소매점 공급사슬을 전체적인 관점에서 효율적으로 운영하기 위하여 공급자가 소매점의 재고를 관리하는 공급자 주도 재고관리(Vendor Managed Inventory; VMI)정책의 도입이 확산되고 있다. VMI 정책은 소매점에서 직접 수행하는 재고관리(Retailer Management Inventory; RMI)와는 달리 소매점의 재고수준에 대한 의사결정과 재고유지에 대한 재정적인 책임이 소매점으로부터 공급자에게 옮겨진다. 이에 따라 소매점은 공급자로부터 수시로 재고를 보충 받게 되고 주문절차는 사라진다. 또한 재고공간의 크기를 줄일 수 있게 된다. 공급자 또한 전체 소매점에 대한 효율적인 분배로써 비용절감의 효과를 기대할 수 있게 된다. 본 연구에서는 품절을 고려하며 소매점의 판매수요가 확정적인 상황에 대하여 RMI와 VMI에 대한 총비용을 최소화하는 수리모델을 통해 총비용 관점에서 RMI와 VMI정책을 비교하고자 한다. 계산실험을 통해 RMI와 VMI의 총비용 변화에 민감한 요인들을 분석하였고 VMI 적용으로 총비용을 절감시키기 위한 조건을 모색하였다. 실험결과, VMI의 적용은 항상 총비용 절감 효과를 나타내는 것이 아님을 확인 하였고 RMI에 대한 VMI의 총비용 증감효과는 RMI 정책의 소매점 주문비와 VMI정책의 소매점 재고공간의 크기 변화에 가장 크게 영향을 받는 것으로 나타났다. 이를 토대로 간단한 소매점 공급사슬에 대해서 VMI의 총비용 감소조건을 제시하였다.

Nuclear issue is a good example showing globalization of the international regime. The history showed nuclear weapons may cause the extinction of human races when the first nuclear bombs fell down to Japan in August, 1945 and people became increasingly eager to achieve peace. Military buildup for national security is a matter of existence in the international society. However, disarmament or arms control to secure international peace and safety which is also the purpose of the Charter of the United Nations may be the most important task for us to realize peace of the mankind. Today, disarmament, together with amicable settlement of international conflicts and collective security system, is an important means to maintain and promote international peace and safety. It might be our permanent task to realize complete disarmament but, as the Preamble of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) expressed general and complete disarmament, the international society has clarified its effort for complete disarmament. Thus, taking a look into the international regime on the nuclear issue and progress related to the nuclear issue in North Korea, the study was intended to introduce the globalization of the nuclear issue, review the international effort for nuclear disarmament based on the concept of the 'common heritage of the mankind' and with respect to the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) and controls over nuclear weapons, and then evaluate the North Korean nuclear issue, which is in direct relation with South Korea and international laws, in terms of the space law and disarmament acts. The collective security system along with policies to prevent dissemination of nuclear weapons should also be emphasized and implemented to cope with the North Korean nuclear issue.

We examine the current status of smart factory deployment and diffusion programs in Korea, and seek to promote manufacturing innovation from the perspective of SMEs. The main conclusions of this paper are as follows. First, without additional market creation and supply chain improvement, smart factories are unlikely to raise profitability leading to overinvestment. Second, new business models need to connect "manufacturing process efficiency" with "R&D" and "marketing" in value chain in smart factories. Third, when introducing smart factories, we need to focus on the areas where process-embedded technology is directly linked to corporate competitiveness. Based on the modularity-maturity matrix (Pisano and Shih, 2012) and the examples of U.S. Manufacturing Innovation Institute (MII), we establish the new smart factory deployment policy measures as follows. First, we shift our smart factory strategy from quantitative expansion to qualitative upgrading. Second, we promote by each sector the formation of industrial commons that help SMEs to jointly develop R&D, exchange standardized data and practices, and facilitate supplier-led procurement system. Third, to implement new technology and business models, we encourage partnerships, collaborations, and M&As between conventional SMEs and start-ups and business ventures. Fourth, the whole deployment process of smart factories is indexed in detail to identify the problems and provide appropriate solutions.

This study analyzed the policy of culture welfare in libraries for the information alienated groups. This study suggested several improvements as a conclusion. Research analyzed organizational tasks and policies for Ministry of Culture, Sports and Tourism, Planning Group for Library and Information Policy and the policies for libraries. First, library service for alienated class was centered in short term period projects. Second, it is hardware oriented such as building small libraries, places for disabled person, multi-cultural libraries. Due to the decentralization of policies for the groups with alienated information, and lack of public supportive policies for private library for the disabled, developing cooperative system is difficult. Third, we revealed that policies for quantitative production of alternative material were achieved. So, this study suggested professional policy in integrative cooperation in accordance with each domain and creation of a separate welfare library policy department and its activity.

'Vision Zero' is a fundamental response to rapidly increasing number of traffic accidents. It was first introduced in Sweden in the late 20th century and is spreading worldwide. 'Vision Zero' criticizes an existing traffic safety policy that presupposes a reasonable human beings. It suggests that traffic safety policies should be on the possibility of making mistakes by irrational beings. Under the ethical vision that human life and health cannot be exchanged for any other social benefits, the policy issue should allow to make zero out the death rate and serious injuries of traffic accidents while allowing minor injuries. 'Vision Zero' argues that the government should design an environment in which individual mistakes never lead to fatal accidents. 'Vision Zero', which shows a different perspective from existing policies regarding safety ultimate goal, is spreading from traffic safety to other areas such as health, safety and well-being. This study examines the implication of the Korea's school safety policy from the perspectives of 'Vision Zero' on the five areas : "for what", "from what", "by what", "by whom", and "how". The study is intended to establish a new directions and challenges of school safety policy in Korea through an analytical discussions on 'Vision Zero'.

도시확산과 지방분권화의 시대적 추세는 도시경제 및 교통-토지이용모형의 구조에 도 영향을 미치고 있다. 첫째, 도시의 공간적 확산과 고밀도화로 인한 도시내 제반 경제.사 회활동이 이전보다는 훨씬 다양해지고 복잡해지고 있다. 둘째, 지방분권화로 인해 대도시내 작은 지역단위별 주민들이 자신의 지역문제에 대한 관심과 요구들이 증가하고 있다. 또한 대부분의 도시계획 및 정책은 대도시내 공간적으로 뿐만 아니라 서로 다른 이익집단에 상이 한 영향을 미치는 것으로 파악되고 있다. 이러한 요인으로 인해 대도시 모형은 1) 도시내 제반활동의 흐름을 체계적으로 분석할 수 있어야 하며, 2) 도시계획 및 정책의 효과를 도시 내 세분화된 공간별, 업종별로 분석할 수 있어야 한다. 본 연구는 Wilson의 모형에 도시내 중요한 경제활동인 통근과 shopping변수를 추가하여 Wilson의 모형이 대도시모형으로 이용 될 때 발생하는 문제를 해결하였다. 또한 모형을 구성함에 있어 Matrix Inversion과 Non-linear Programming Model의 두 가지 방법을 도입하고 그 장단점을 비교하였다. Matrix Inversion의 경우 해 (Solution)을 찾기가 쉬워 실질적이고 승수계산과정에서 각 Round마다 승수의 크기를 알 수 있는 반면 Programming을 통한 모형의 경우 제약식의 도 입이 용이하고 목적함수의 형태를 바꾸는 것이 가능하므로 이론적 기틀을 세우는데 유리한 접근방법으로 분석되었다.

About 35 domestic incinerators are being operated currently. There is waste management policy to reuse waste efficiently and reduce waste through incineration which include reuse, recycling and energy recovery. However, there is a critical social issue that some heavy metals(Cu, Pb) were found in bottom ash from incineration of waste. After incineration, bottom ash is treated with chemicals to prevent second pollution of heavy metals from bottom ash and increase efficiency of heavy metal stabilization.

The purpose of this study is to investigate how the advertising campaign is spreading in social networks, and how the advertising model plays an important role in advertisement diffusion. In order to grasp the diffusion patterns of advertising, a text mining and social network analysis were conducted using the beer brand 'Kloud' as a collection keyword. After analyzing the social data for two months since the on-air of 'Good Body' advertisement, which was the first ad that "Sulhyun" appeared in. After the launch of the ad, Kloud has been mainly associated with keywords such as 'yavis & trendy style', 'beer brand', 'beer matching food', 'luxury beer drinking place', 'leisure trend', and 'SNS activity', etc. In addition, "Sul Hyun" also showed that an advertising model contributes to the spread of advertisement on social media in terms of image transition as well as brand's name and unique selling point.
