In a situation where the amount of bulky waste needs to be quantified, a three-dimensional model of the wastes can be constructed using drones. This study constructed a drone-based 3D model with a range of flight parameters and a GCPs survey, analyzed the relationship between the accuracy and time required, and derived a suitable drone application technique to estimate the amount of waste in a short time. Images of waste were photographed using the drone and auto-matching was performed to produce a model using 3D coordinates. The accuracy of the 3D model was evaluated by RMSE calculations. An analysis of the time required and the characteristics of the top 15 models with high accuracy showed that the time required for Model 1, which had the highest accuracy with an RMSE of 0.08, was 954.87 min. The RMSE of the 10th 3D model, which required the shortest time (98.27 min), was 0.15, which is not significantly different from that of the model with the highest accuracy. The most efficient flight parameters were a high overlapping ratio at a flight altitude of 150 m (60-70% overlap and 30-40% sidelap) and the minimum number of GCPs required for image matching was 10.

The purpose of this study is to propose strategies for enhancing competitiveness through the utilization of policy funds, especially in the start-up companies supported by the Korea Credit Guarantee Fund. And then, the Korea Credit Guarantee Fund should develop 'user-centered policy funding model' in order to increase start-up's utilization of policy fund and support start-ups that are supported in the long run. The competitiveness of domestic start-up companies has been strengthened by 'user-centered policy funding model' and new innovations have been introduced through 'Living Lab', an open innovation. But, in order to overcome the limitation of reaching the stage of commercialization, the 'user-centered policy funding model' proposed in this study enables start-ups to be the subject of actual policy funding, and also allows users to freely apply for necessary funding at any time. Therefore, the Korea Credit Guarantee Fund has a significance in suggesting 'user-centered policy funding model' as a support model to be customized. However, since SMEs recognize the actual situation and limit acceptance of all the difficulties, the systematic analysis of the actual situation of the policy funds of the start-up by the credit guarantee fund and the related support institutions for the scientific approach of the user-oriented policy funding model need.

A collection development policy is the library's master plan that provides library's long/short-term plans. It also informs the community of the library's commitment in collection development. However, in Korea, libraries which maintain such a policy are not yet to be easily found. Furthermore, due to increasing importance of electronic resources, libraries are gradually required to have electronic resource management policy that reflects a change in the information environment. The purpose of this study is to suggest a model electronic resource management policy in academic libraries. It derived and verified more than thirty preliminary elements from literature and case studies. The elements were modified and supplemented, and as a result, the selection criteria gained the highest marks. The findings can be applied for selecting the elements of digital collection development policy in the university library and reorganizing them so as to meet its peculiarities. This study, finally, presents a model that includes a guideline for the university library which will establish digital collection development policy.

The purpose of this study is to propose established factors and a model of collection development policies for the libraries of theological universities in Korea. To achieve purpose of the study, we analyzed of elements and details of collection development policies at libraries of theological universities in overseas. The study then conducted a survey to understand the current status of collection development policies at libraries of theological universities in Korea. Based on the above results, reflecting both the external and the internal factors, the investigator presented a model of collection development policies by identifying seven elements that should be included when developing the policy: prefaces, collection selection, collection gathering, budget, collection maintenance, mutual cooperation and intellectual freedom, and revision of collection development policies.

This study proposed an evaluation method of mobile emissions reduction strategies for air quality management. The proposed method was considered Travel Demand Model (TDM) and Analytic Hierarchy Process (AHP), while an existing method was focused on quantitative factors. AHP of the evaluation indices of mobile emissions reduction strategies show that quantitative evaluation indices such as air pollutants and greenhouse gas reduction are more important than the political evaluation indices (Consistency with an upper plan, Policy applicability, Technical applicability and feasibility) and each weight of air pollutants and greenhouse gas reduction are found to be 0.373 and 0.218. The early scrapping policy of decrepit diesel vehicle is the best policy in the proposal method using TDM and AHP but this result differs from evaluated result by TDM or AHP respectively. These results are limited to the basic assumption and range of reduction scenarios but are expected to contribute to establish more reasonable and effective mobile emission reduction strategies.

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.

본 연구는 2011년 "원자력안전법" 제정 사례에 있어 정책의제 설정 과정을 동태적으로 이해하기 위해 다중흐름모형을 활용하여 분석을 수행하였다. 연구범위는 이명박 정부와 제18대 국회임기가 겹치는 기간인 2009년부터 2011년 간 기간으로서, 동 기간은 UAE 원전수출과 후쿠시마 원전사고라는 정 반대의 초점사건이 발생하면서 두 차례 의제설정 여부를 결정하는 정책의 창이 개방되었다. 분석결과, 문제의 흐름 영역에서는 정부의 원자력 정책에 있어 진흥과 규제기능을 별도 법령으로 분리하고 독립된 예산 및 전담조직을 구성하는 체계를 구축해야 한다는 문제는 장기간 존재해왔다. 1990년대부터 소수의 법학자들을 중심으로 문제인식과 대안제시가 이뤄지는 정책의 흐름이 발전되어 왔는데, 이후 UAE 원전수출 이후 2010년에 이르러서야 본격적으로 표출집단인 관료와 국회의원을 통해 구체적 대안이 제시되었고, 2011년 후쿠시마 원전사고 직후인 5월 원자력안전법이 제정되었다. 분석결과, 2009년 UAE원전수출 이후, 수출 확대 목적으로 제시된 원자력 규제 독립 법안이 통과되지 못했던 것에 반해, 2011년 후쿠시마 이후 원자력안전법이 통과 된 이유는 대안의 가치정합성, 사회여론, 정치환경 등 정치의 흐름이 크게 작용한 것으로 분석되었다.
