최근 기후변화로 인하여 자연재해 발생 빈도가 증가하고 있으며 우리나라의 경우, 자연재해 중에서도 태풍, 호우 등 풍수해의 발생 비율이 높게 나타난다. 최근 곤파스(2010), 무이파(2011), 볼라벤(2012) 등 태풍의 영향으로 많은 인명피해와 1조원 이상의 직접손실이 발생하였다. 이로 인하여 자연재해 예측 및 피해저감을 위한 국가적 차원의 체계적인 방재정책을 수립하고자, 안전관리 기본계획 및 풍수해저감종합계획 등 풍수해 관리를 위한 관련 정책들을 정비하고 있다. 그러나 현행 법률구조상 효율적인 재난관리정책을 뒷받침할 법적 근거가 미흡한 실정이다. 이에 본 연구는 체계적인 풍수해 관리를 위하여 재난관리단계를 예방, 대비, 대응, 복구로 구분하고 관리 현황 분석을 진행하여 풍수해관리 중장기 전략을 제시하였다. 연구방법으로는 풍수해 관련 법령 및 법 제도 체계를 검토하였고, 루사(2002)와 볼라벤의 피해사례 분석을 통해 풍수해 관리 문제점을 파악하였다. 현행 방재정책은 사후복구위주의 중앙정부 중심 체계이며, 피해규모가 대형화되고 복합재난이 발생하는 등 새로운 재해상황을 반영하지 못하고 있는 것으로 분석되었다. 따라서 본 연구에서는 기존 풍수해 관리에 있어 (1)관련법 규정의 미흡, (2)재해정보의 부족 및 정보관리의 미흡, (3)대응체계의 복잡성, (4)방재산업에 대한 전략적 과학적 투자 미흡 등을 문제점으로 도출하였다. 이와 같은 문제점을 개선한 풍수해관리 중장기 전략은 첫째, 법 제도 개선을 통한 풍수해 관리수준 고도화, 둘째, 재해연보 개선을 통한 풍수해정보관리 고도화, 셋째, 풍수해 피해예측시스템을 활용한 계획적이고 체계적인 재난대응체계 구축, 넷째, 풍수해 저감 핵심기술 확보와 국내 방재산업 활성화 체계 구축으로 제시하였다.

This research examines how IoT makes a significant contribution to the innovation of media firms. The media firms will be able to find new reveue sources and strengthen firms' competence through innovating product, process and business model. While IoT increases the experience of interactivity and immersion for consumption, it improves the way ads are exposed and its impact is measured, leading to revenue increase. For these benefits fulfilled, innovation friendly media eco-system must be established. It is the most critical that media firms should change skeptical attitude toward IoT's potential and actively invest it to employ IoT. The government should create regulatory framework to best utilize the innovative advantages of IoT.

Today many companies are offering IoT-enabled products and place emphasis on security from the planning stage to protect their products and user information from external threats. The present security levels, however, remain low because the time and resources invested in developing security requirements for each device are far from enough to meet the needs of a wide range of IoT products. Nevertheless, vulnerabilities of IoT devices have been reported continuously, which calls for more detailed security requirements for home IoT devices. In this context, this research identified threats of home IoT systems by using Microsoft Threat Modeling Tool. It then suggested measures to enhance the security of home IoT devices by developing security assessment items through comparative analysis of the identified threats, domestic and global vulnerability assessment standards and related research. It also verified the effectiveness of the developed security requirements by testing them against the existing ones, and the results revealed the security requirements developed in this research proved to be more effective in identifying vulnerabilities.

While the Design for Safety (DFS) system has been introduced to Korea, the ordering parties and designers who are implementing this system still have a very low awareness of it. Most ordering parties and designers have a negative view of this system due to a variety of reasons, including the additional workload and their lack of professional manpower. The purpose of this study is to suggest measures to improve the DFS work performance by standardizing the DFS work process and analyzing the level of work performance in each business carried out by ordering parties and designers in order to ensure the efficient execution of DFS business. In conclusion, to improve the DFS work performance of ordering parties and designers, the development of a business support system is suggested, which supports key works such as the identification of risk factors, the provision of measures to reduce such factors, and risk assessment, and provides relevant information to allow ordering parties and designers to prepare the DFS report smoothly.

Although social economy organizations have achieved quantitative growth in various types and fields, they have been mainly promoted by the government, and there is still room for qualitative improvement, such as institutional reorganization, support systems and support methods, compared to advanced countries. In this study, the problems of social economy organizations, the current status and actual analysis of social economy organizations, the policy delivery system, obstacles to the development of social economy organizations, and problems of activation, etc. were reviewed through previous studies. Through this, policy directions and tasks for revitalization of future social economy organizations were presented. As a result, the policy direction for revitalization of social economy organizations requires private and local government initiatives, expansion of fields, customized support for the creation of a growth ecosystem, and various linkage cooperation. Organizational capacity development and education, reinforcement of various linkage cooperation systems, creation of an investment ecosystem, and joint market development are necessary.

Electronic detonators are now widely used in various construction sites and quarry mines. Including the sites where safety-thing is located nearby, Cases of using electronic detonators are increasing to maximize operational efficiency by improving blast fragmentation or reducing the cost of secondary blasting. This case study is about applying for electronic detonators on zone 00 construction site, which is the part of urban area metropolitan express rail A line project. Although the project was initially planned to utilize non-electric detonators, Electronic detonators are considered as the solution not only for safe and fast excavation, but also to minimize civil complaint and the damage of safety-thing. By applying electronic detonators, we were able to satisfy environmental regulations standards and prevent nearby safety-thing from getting damaged.

Today, disturbance and paralysis of information and communication infrastructure by electronic infringement of national infrastructure is emerging as a threat. Accordingly, the government regularly implements the vulnerability analysis and evaluation system of major information and communication infrastructure to protect the information system and control system of major infrastructure, and invests increased human and material resources every year to efficiently operate it. However, despite the government's efforts, as infringement accidents and attempts targeting national infrastructure continue to occur, the government's resource input to prepare the information protection foundation has little effect on the information protection activity result calculation, making the evaluation system not efficient. The question arises that it is not. Therefore, in this study, we use the DEA model to review the efficient operation of the vulnerability analysis and evaluation system for major information and communications infrastructure, and suggest improvement measures to enhance the level of information protection based on the analyzed results.

The setting of the target area for ground stability evaluation during ground excavation is categorized into theoretical and empirical estimation methods and numerical analysis methods. Generally, the applied theoretical and empirical estimation methods include those by Peck (1969), Caspe (1966), and Clough et al. (1990). The numerical analysis method comprehensively considered the current status of the task section (maximum excavation depth section, ground condition vulnerable section, etc.). It reflected the results of performing two and three-dimensional numerical analyses on the weakest section. Therefore, this study shows an example of setting the scope of influence when excavating the vertical and tunnel sections of a 000-line double-track private investment project through the above theoretical, empirical, and numerical analysis methods.

The semiconductor manufacturing process normally includes a great number of complex sequential steps those are related with various types of equipment. Such equipments are installed with the mixed patterns of serial or parallel structures while considering a number of engineering or environmental factors at the same time. It is thus extremely difficult to change the layout after installation due to expensive costs and other related factors. Because of these reasons, a new investment or layout change, which is usually caused by the production policy such as product mix or production quantity, must be carefully considered. This case study introduces a simulation conducted in a semiconductor parts production company which produces the Board on Chip (BOC)-type of packaging substrate and has plans to change the facility layout. For this study, we used $QUEST^{(R)}$ for simulation modeling and evaluated various strategies which may cause layout changes. Further, the Analytic Hierarchy Process (AHP) is applied to select the best strategy from several alternatives with multiple decision criteria.
