This study conducts an empirical analysis of how the suggestion activity, most widely used in quality control activities, interacts with the dimensions of learning organizations. The study also attempts to analyze the results of Six Sigma based on sub-dimensions of learning organizations, which are infrastructure, culture and system. In order for learning and innovation to take place in implementing a Six Sigma program, the organizational infrastructure and culture are created and sustained and then, a learning organization system would become effective. In this study, a empirical model is used to demonstrate such an association. The sample consists of 134 organizations who have implemented a Six Sigma program for more than three years. Using the version 16.0 of AMOS for structural equation modeling, the study estimates the structural equation model that has a Six Sigma organization's infrastructure, culture and system as independent constructs, the suggestion system as a mediator, and the performance of Six Sigma projects as a dependent construct.

민간투자사업은 정부에는 민간의 자본과 기술을 도입하고 민간은 정부의 공공재를 안정적으로 사용하여 수익을 창출할 수 있다는 상호이익으로 인하여 계속 활성화되고 있다. 국제적으로는 1980년대, 우리나라의 경우 1990년에 들어 도로, 철도, 항만, 공항 등의 사회간접시설(SOC) 사업이 증가하였다. 본 연구는 민간투자사업의 기본이 되는 민간투자법의 전반적인 부분을 고찰하고 쟁점 사항에 대한 개선방향을 도출함으로써 "민간의 투자를 촉진하고 국민경제 발전에 이바지 한다"는 민간투자법의 목적을 합리적으로 달성하고자 한다.

스마트 그리드는 기존 전력망에 IT 기술을 접목하여 에너지 효율을 최적화하는 차세대 지능형 전력망으로 미국, 유럽, 일본 등 전 세계적으로 기술개발이 이루어지고 있으며 실증사업을 추진하고 있다. 최근 스마트 그리드에 대한 공격 사례가 증가되고 있으며 개인정보의 사용 및 유출의 피해가 높아지고 있다. 전력망이 더욱 복잡해지고 상호 연결됨에 따라 보안 분석과 평가에 대한 노력이 점차 중요해지고 있다. 본 논문에서는 스마트 그리드의 핵심 기술인 AMI(Advanced Metering Infrastructure)의 공격과 공격에 대한 대응책을 ACT(Attack Countermeasure Tree)를 이용하여 모델링 하였다. 보안 분석은 확률이 있는 경우와 확률이 없는 경우로 나누어서 수행하였다. 이러한 모델을 가지고 SHARPE(Symbolic Hierarchical Automated Reliability and Performance Evaluator)로 구현하여 다양한 경우의 확률과 ROA, ROI, Structure Importance, Birnbaum Importance에 대해 계산하였다.

공간정보를 기반으로 하고 있는 GIS가 행정업무 처리와 대민서비스 향상을 위한 핵심 수단으로 활용됨에 따라 지방자치단체의 GIS도입 및 확산이 급속히 이루어지고 있다. 최근의 급속한 GIS활용 확산에도 불구하고, 중대도시에 비하여 농촌과 지방소도시의 지리정보기반은 아직도 크게 미흡하다. 지리정보기반의 지역간 수준격차는 공공행정서비스의 질적 수준 격차는 물론 궁극적으로 지역간 사회경제 격차를 심화시키는 요인이 된다. 이 연구는 지리정보기반 개념을 규정하고 우리나라의 수도권과 비수도권 등의 지역 및 지자체 유형별 지리정보기반 수준의 격차수준을 분석하였다. 그리고 이러한 지리정보기반 수준의 지역간 격차요인을 검토하고 특히 지리정보기반이 취약한 지방소도시 및 군부지역의 지리정보기반 강화방안을 제시하였다.

The Republic of Korea developed a national project to construct a new administrative capital, Sejong city and to relocate administrative organizations of the central government for improvement of overpopulated capital, Seoul and regional balanced development. By the way, to relocate the central administrative organizations was not a sufficient condition for the sustainable development of the city. An industrial infrastructure development has been tried to attract universities, enterprises and research institutions in the region as a demand for internal growth power of the city was increased. In addtion, a basis for regional endogenous growth through projects to establish innovation system based on industry-academia cooperation was prepared as well. This paper reviews the major contents of the development plans for Tech-Valley project and looks into major introductory functions, characterization plans, strategies for fostering strategic industry, cooperation system of the inside and outside the region, and a strategy for building innovation platform. This case can be regarded as a significance of constructing technology infrastructure for the sustainable growth by preparing foundation for establishing innovation system and a cluster based on this system in the process of building and developing new city which did not have any industrial platform in the region.

In this paper, a survey related to excavation construction activities among national and international construction companies was conducted to evaluate site productivity in construction industry. To analyze the respective productivity levels of each construction company, a benchmarking measures analysis that featured calculations of the performance ratio (PR) and performance management index (PMI) was performed. As a result of these analyses, it has been found that the work performed by local companies was marked by lower productivity and that of international companies was characterized by good productivity. Further analysis of construction workforce resources P% revealed that a construction company's productivity is largely dependent on production capacity and consumption resources, which means that the retention of skilled workers and utilization of high-quality resources yields the highest level of productivity. These results suggest that for a local construction company to be competitive in the construction work market, it must retrain skilled craftspeople, foremen, engineers, and project managers, and strengthen its building capability by leveraging new equipment and technologies.

This study considered measures to support the establishment of surveying and spatial information in preparation for the unification of South and North Korea and the subsequent construction of national infrastructure. The organization identified and analyzed spatial information about North Korea, road and railway-oriented SOC construction projects, and examined the applicability of the latest technologies to narrow the technical gap with North Korea and quickly establish land spatial information. To prepare a support process appropriate for the situation in North Korea, technical and human support details and considerations were reviewed through a case analysis of spatial information construction for developing countries. In addition, the main result was "Presenting Efficient Utilization of Human Resources and Equipment for the Establishment of Spatial Information in North Korea," establishing an efficient utilization plan for the human resources and equipment needed in the support process based on technology support. It is expected that the South Korean government will minimize the negative impact on future land infrastructure construction by first conducting research in inter-Korean economic cooperation and national infrastructure construction and establishment of spatial information construction plans.

환경부에서는 2013년부터 소규모 분산식 빗물 관리 방식인 '그린빗물인프라(Green Stormwater Infrastructure, GSI) 조성 사업'을 추진하여 설치비를 지원함에 따라 각 지자체의 GSI 조성 사업은 매년 증가하고 있다. 하지만 「저영향개발 사전협의제도」를 도입하고 있는 서울시를 제외하면, 각 지자체별 가이드라인, 추진체계 부존의 문제로 도입에 어려움을 겪고 있다. 이에 본 연구에서는 경상남도를 대상으로 공공청사의 적용 범위 및 우선 순위 설정, 시범 구역 GSI 적용 효과 검토를 수행하고 이를 통합한 추진체계 구축을 연구 결과로써 제안하고자 한다.

Benefit-cost analysis is one of key elements of feasibility study on a large scale investment for transportation infrastructure improvements. Benefit-cost analysis requires measuring expected benefits after the investment is completed. Reduction of delays is the major source for the benefit among other measurable benefits. Measurement methods for delays reduction have been reviewed and two methods were recommended for passenger delay and aircraft operation delay. Using these method, the effects of Cheju International Airport Improvement Projects were evaluated.
