Last-Mile delivery optimization plays a key role in the urban supply chain operation, which is the most expensive and time-consuming and most complicated part of the whole delivery process. The urban consolidation center (UCC) is regarded as a significant asset for supporting customer demand in the last-mile delivery service. It is the key benefit of UCC to improve the load balance of vehicles and to reduce the total traveling distance by finding the better route with the well-organized multi-leg vehicle journey in the urban area. This paper presents the model using multiple scenario analysis integrated with mathematical optimization techniques using Geographic Information System (GIS). The model aims to find the best solution for the distribution network consisted of DC and UCC, which is applied to the case of Ulaanbaatar Mongolia. The proposed methodology integrates two sub-models, location-allocation model and vehicle routing problem. The multiple scenarios devised by selecting locations of UCC are compared considering the general performance and delivery patterns together. It has been adopted to make better decisions the quantitative metrics such as the economic value of capital cost, operating cost, and balance of using available resources. The result of this research may help the manager or public authorities who should design the distribution network for the last mile delivery service optimization using UCC within the urban area.

The supply chain without digitization is just a series of discrete, siloed steps taken through marketing, product development, manufacturing, and logistics, and finally into the hands of the customer. Digitization brings down those walls, and the chain becomes a completely integrated network fully transparent to all the parties involved. The ulitimate goals of digitizatized supply chain management are velocity and visibility. This network will depend on a number of key technologies including integrated planning and execution systems, supply chain analytics, autonomous logistics, smart warehousing and factory, etc, enabling companies to react to disruptions in the supply chain, and even anticipate them, by fully modeling the network, creating "what-if" scenarios, and adjusting the supply chain in real time as conditions change. This paper presents a number of studies on digitalization of supply chains and provides a discussion on issues raised in the process of technology adoption. Implications of the study findings are also provided.

선진국의 경제구조가 서비스경제로 전환됨에 따라 고부가가치를 낼 수 있는 지식기반 (Knowledge-based) 또는 기술기반 (Technology-based) 서비스의 중요성이 부각되고 있으며 서비스 기업들간의 경쟁도 매우 치열해지고 있다. 서비스 기업들은 보다 차별화 된 고객가치를 창출하고 미래의 핵심역량을 확보하기 위해 다양한 활동을 전개하고 있으나 제조기업과는 달리 대부분의 서비스 기업들에게 연구개발 (Research and Development, R&D)이라는 개념은 매우 생소한 상태이다. 최근 유럽을 중심으로 서비스기업의 연구개발에 관한 논의가 활발히 진행되고 있지만 서비스기업의 특성을 포괄하는 연구개발에 대한 정의를 내리는 수준에 머물고 있다. 최근 우리나라 정부에서도 서비스 연구개발에 관한 정책입안을 위해 연구를 진행하고 있는바, 서비스기업에서의 연구개발에 대한 정의, 조직, 예산, 활동영역, 산출물 및 이에 따른 정책적 지원 등에 관한 학계에서의 연구는 거의 이루어지지 않고 있는 실정이다. 본 연구에서는 서비스기업의 연구개발활동을 도출하고 연구개발투자와 기업성과와의 관계를 분석함으로써 효과적인 연구개발 투자규모를 도출하는 것이 목표이다. 이 때 서비스기업의 연구개발활동이라 함은 연구개발 대상, 수행조직, 연구개발의 중요성이 포함된다. 또한 연구개발투자와 1-2년 후의 매출 및 순이익의 변화를 분석한다. 실증분석을 위해 기술기반 서비스를 대표하는 국내 IT서비스 기업을 대상으로 설문조사를 실시하였으며 다양한 통계분석을 활용하였다. 연구결과 대부분의 서비스 기업 응답자가 연구개발의 중요성을 크게 느끼고 있는 것으로 나타났다. 기업마다 부서별 또는 중앙 연구개발센터를 중심으로 다양한 연구개발활동을 수행하고 있으며 연구개발투자가 기업성과로 연계되기 위해서는 최고경영자의 관심이 가장 중요한 요인인 것으로 지적되었다. 가장 효과적인 연구개발 투자규모는 매출액 대비 15-19%인 것으로 분석되었는데 이는 벤처기업의 특성을 갖는 중소 IT서비스 기업들의 참여가 많았기 때문일 것으로 해석된다. 본 연구의 결과는 우리나라 서비스기업들이 미래준비를 위한 활동을 전개함에 있어 고려해야 할 주요 요인들을 제시해 줄 것이다.

The recent cyber threats are becoming real threats to our lives. This gloomy situation from cyber threats necessarily demands the establishment of the cyber threat information sharing system between the public and private area. Key countries, like the US, Japan and the UK, are stabilizing the cyber threat information sharing systems by founding exclusive organizations for sharing information and setting up and implementing relevant measures. In this thesis, I would like to propose the model for cyber threat information sharing in order to cope efficiently with the ever-intensifying cyber threats. My model would include key elements for the efficient information sharing, such as the clear designation of main operator of information sharing system, the management of collaboration system between the public and private sector, the build-up of the integrated and automated system and the supplementation of legal system including the grant of privilege, and so on.

국립과천과학관은 상설전시관 외에 천체관측소, 천체투영관, 스페이스월드 등의 천문우주시설을 갖추고 있으며 이들 시설을 활용한 천문대중화 프로그램을 지속적으로 운영하고 있다. 그러나 학령인구 감소와 관람객의 요구수준 증대 및 계층의 다변화에 따라 더 이상 과학관 간의 경쟁이 아닌 문화센터, 놀이공원, 박물관 등 여러 유형의 놀이, 문화 시설과 경쟁해야 하는 현실에 직면하고 있다. 이로 인해 과학관을 방문하는 관람객수는 정체하거나 점차 줄어드는 추세를 보이고 있다. 따라서 일정한 수준의 관람객을 지속적으로 확보하기 위해서는 새로운 수요를 창출하는 것 못지않게 과학관 관람객층을 다변화하고 이들의 재방문율을 높이는 것이 중요하다. 2016년 1월부터 2017년 7월까지 국립과천과학관 천문우주시설의 비 상설 프로그램인 "공개관측회"와 "저자특강"에 참석한 관람객을 대상으로 재방문율 조사를 하였고 이를 이용해 관람객의 프로그램 참석 빈도, 특성, 고객충성도 등을 분석하였다. 충분한 표본 확보와 자료의 객관적인 분석을 위해 소수의 적극적인 관람객만 참여하는 설문조사 방식을 사용하지 않고 온라인에 등록된 모든 참석자의 목록을 추출하여 사용하였다. 조사기간 프로그램에 참여한 총 인원은 6,700명이었으며 2회 이상 방문을 한 관람객의 재방문율은 38.8%를 나타냈다. 총 4,755명이 참석했던 "공개관측회" 만을 대상으로 한 재방문율은 29.8%, 총 1,925명이 참석했던 "저자특강"만을 대상으로 한 재방문율 41.7%의 결과를 얻었다. 또한 두 프로그램을 모두 참석한 관람객은 전체 19.6%의 결과를 보였고 재방문자만을 대상으로 한 교차 프로그램 참석자의 비율은 50.4%를 나타냈다.
