There are many type vehicles in army. They are jeep and truck by basic type. Recently many countries are developing new conceptual military vehicles. And they try for export of those military vehicles to another countries. Also Korea Army is developing military tactical and combat vehicles, and considering various necessary factors for export. But as easing the cold war system tension and reducing of defense budget, decrease in quantity of military vehicles. We think this trend is accelerative. Therefore Government(Military) and defense industry make every effort to increasing sales and productions. In this study, I'll inquire '2013~2017 basic plan for defense industry promotion' for strengthen the power of international competitiveness, and then suggest the increasing method for productions of military vehicles.

This study was to find out contemporary planning trends of rural houses in So-yang Munhwa village by analyzing their floor plan shapes and space relations & elements. There were built 71 houses in that village, but it were possible to collect housing data, floor plans & general building records of 45 houses, from house register. By analyzing those data, findings were as follows : 1) Floor plan shapes of rural houses had a tendency to various type than simple types. 2) Room-Living-Room, 3 bay arrangement were very strong trends in those plans. 2) Public spaces, L.D.K(living dining kitchen) spaces, were centered in the floor plan of them. 3) Living space had an openness from entrance and DK(dining kitchen)spaces were separated from L.D.K. 4) Anbang(master bedroom) and living space were important, so two spaces were set to the south of floor plan and Anbang with a bathroom were often showed. 5) Utility and balcony/veranda spaces as a support space of kitchen were planned in rural houses.

Agricultural research and development (R&D) investment has contributed not only to agriculture but also to the overall economic growth of the country. The recent arrival of the fourth industrial revolution has raised the need for agricultural R&D as a preparation. Agriculture R&D is directly related to the fourth industrial revolution in the agricultural and livestock sectors that utilize big data, robots, artificial intelligence and cloud. Meanwhile, subsidies or grants are considered the most widely used means of policy. Therefore, in light of the current situation in which Chinese agriculture values R&D investment, this study attempted to analyze the dynamic relationship between variables by establishing a model of agricultural environment subsidy representing the role of government, agricultural technology progress representing existing agricultural R&D investment, agricultural income representing agricultural development and total agricultural output. The analysis results showed that each variable's reaction to the rise in China's agricultural R&D investment has a positive effect on agricultural development, in line with the theory that the investment in science and technology in the agricultural sector has a positive effect. In addition, the response of each variable to China's rising agricultural environment subsidy is shown to have a positive relationship, which can also be said to be in line with the theory that the government's market-friendly intervention is beneficial to economic development.

소음문제는 대도시 환경문제 중 주요한 문제 중의 하나로 관심이 높으며, 도시계획과 설계분야에 소음지도의 활용이 증가하고 있는 추세이다. 그러나, 기존의 2D 소음지도는 주로 평면적인 소음분포만을 나타내고 있어 최근 고층화, 대형화 되어가는 건물의 각 공간에 대한 미시적 소음분석 및 시각화에는 한계를 갖고 있다. 따라서 본 연구에서는 평면적이고 지역적인 소음분포의 표현에만 머무르고 있는 기존 소음지도의 한계점을 인지하고 소음의 수직적인 분포를 고려하여 공간단위의 소음분석 및 시각화를 위한 데이터모델을 제시하였다. GIS의 토폴로지 구조를 3차원으로 확장함으로써 3차원 공간분석 및 공간단위 시각화가 가능한 3차원 GIS 데이터모델을 제안하고 이를 3차원 소음정보시스템에 적용하고자 하였다. 간단한 3차원 소음정보시스템을 구축하여 3차원 공간질의, 시간대별 3차원 소음시각화, 방음벽의 높이에 따른 소음의 변화량을 시뮬레이션하고 각각의 경우 소음노출가구 및 인구를 정량적으로 산정함으로써 도시계획 및 설계분야에서의 활용가능성을 예시하였다.

President Park Geun-hye Administration has established the Ministry of Science, ICT and Future Planning (MSIP) to build a creative economy using Information and Communication Technology (ICT). July 2, 2013, The National Assembly has legislated the special act on the ICT promotion and convergence so called special ICT Act. This special ICT Act has reduced the legal basis through legislative process and departmental agreement. Therefore many experts worried that since the MSIP's key functions and roles are being reduced, there will be a limit to the MSIP's endeavor for the advancement of science technology and the ICT promotion and convergence. The establishment of the Agency, together with the formation of 'IT Strategy Committee', is considered to be one of the core items of the Special Act on ICT. MSIP originally planned to integrate the ICT R&D functions scattered across many governmental organizations, including Korea Communications Agency (KCA), KEIT and Korea Creative Contents Agency (KOCCA), into the Agency to separate the national ICT R&D from private R&D and streamline the process of 'discovery-selection-evaluation-commercialization'. The analytical results in this study are supposed to the establishment of efficient ICT governance systems as the practical strategies to actively cope with the changes of ICT convergence environment. It is also expected to the revision on the special ICT Act in the ICT budget and governance. Therefore, MSIP should cover research and development (R&D) as well as major ICT promotion functions to a creative economy.

본 연구는 2주탑 3경간 사장교의 사업기획 단계에서 3차원 모델정보에 기반하여 신속한 개략 공사비 및 물량 산정을 지원하는 시스템을 개발하였다. 우선, 기 설계된 사장교 설계정보(구조계산서, 도면, 수량)를 분석하여 설계변수를 도출하였다. 도출된 설계변수를 기반으로 매개변수적으로 사장교를 3차원 모델링하는 BIM Wizard를 개발하였다. BIM Wizard를 이용해 작성된 3차원 모델로부터 사장교의 주요 재료에 대한 수량을 직접 산출하며, 케이블 교량에 대한 단가 D/B와 산출된 수량을 연계하여 개략공사비를 산정할 수 있다. 결과적으로, 사업 초기단계에서 m당 혹은 $m^2$당 실적 평균공사비를 산출하는 재래적인 방식보다 더 구체화된 공사비를 산출할 수 있는 시스템을 구축하였다. 이로써, 우리는 사장교에 대해 입찰단계에서 가능한 신속하게 다양한 대안을 검토할 수 있을 것이다.

This paper describes techniques for the automated creation of geometric 3D models of the urban area us ing two 2D laser scanners and aerial images. One of the laser scanners scans an environment horizontally and the other scans vertically. Horizontal scanner is used for position estimation and vertical scanner is used for building 3D model. Aerial image is used for registration with scan data. Those models can be used for virtual reality, tele-presence, digital cinematography, and urban planning applications. Results are shown with 3D point cloud in urban area.

This paper is on 3D virtual reality simulator for terminal in connection with terminal operation system in real terminal in order to reflex complicated terminal operation and environment. This simulator has been developed based on knowledge of terminal planning and operation analysis and advanced software technologies that TSB has accumulated over 10 years. In this study, the simulator generates terminal layout and component of terminal in the same environments as the real terminal in Ohi, Japan and uses real operation system using real planning data in the past in order to describe 3D VR simulation that integrates container handling equipment and real time communication of job ordering. In addition, it is suggested various statistics and analysis report can be used to derive decision supporting factors that optimize design of terminal and improve operation, which will eventually increase terminal productivity.

The widespread of IT technology caused a remarkable change in many industries and the construction industry is also one of them being influenced in the form of CIC(Computer Integrated Construction) and BIM(Building Information Modeling). Construction projects have many participants from various disciplines involved throughout the entire process. Therefore the success of the project greatly depend on the efficiency of decision-making using the information generated from each process stage. Looking from this aspect, the greatest potential value lies in the planning and pre-design stage when considering the construction life cycle. In this paper, we propose a project on developing a 3D object oriented simulation system for supporting the pre design phase. We define the needs for such system through previous case studies and suggest a to be process model. Finally we anticipate the effects that the project will eventually contribute to the construction industry.
