This study aims to examine the ripple effect of the '119 Integrated Information System' for city disaster management on the local economy. The study was conducted in the area of Gyeongnam province, and the study method is the interdependence analysis based on the Input Coefficient drawn from Input-Output Tables in which Intermediary Transaction Tables drawn through RAS was taken advantage of to grasp the correlation among industries and regions in terms of the local economy, and the ripple effect of the changes of political exogenous variables on the local economy was divided to such elements as production, added value, and employment so as to attempt empirical analysis on the local economy system. To estimate the ripple effect on the local economy, three different amounts of the expected input were applied to the study respectively and the results are as follows: Some $28.7{\sim}42.4$ billion won for the production induction effect, some $7.5{\sim}11.4$ billion won for the added-value induction effect, some $103{\sim}157$ job openings for the employment induction effect, and some $3.8{\sim}5.7$ billion won for the income induction effect are expected to take place as the ripple effect on the local economy.

The increase in the use time of tunnel users due to the lengthening of the road tunnel may increase the evacuation time in case of fire, resulting in a large number of casualties. In order to reduce the casualties caused by fire, the "Road Tunnel Design Manual, Part 6 Tunnel" and "Road Tunnel Disaster Prevention Facility Installation and Management Guidelines" stipulate that ventilation facilities should be installed along with the extension of the tunnel. The ventilation system design factor considers the wind speed of the external natural wind to be at least 2.5 m/s, and it is applied upward according to the characteristics of the tunnel. As a result of analyzing the five-minute average wind speed data in the Daegwallyeong region for the past 6 years, it was analyzed that 15.8% of the windy days were winds of 10 m/s or more, and the maximum was 20 m/s. Therefore, in this study, when a fire occurs in a tunnel, the pattern of natural wind flowing into the tunnel and the backlayering distance of the tunnel fire smoke according to the maximum wind speed were analyzed. As a result, it was analyzed that a backflow of up to 490 m occurs when a gust of 20 m/s blows.

In lately, it's been developed and used a system of using deck plates as formwork in order to solve various problems caused by conventional formwork system. This system is more economical and has higher constructability than the conventional system by permanently embedding most of deck plates into the members. However, for this kind of embedded deck plates formwork system, it's been reported that it is difficult to verify filling of concrete in members like beams with narrow width and complicated rebar arrangement. In addtion, there are several problems such as corrosion of deck plates in terms of constructability and maintenance. Therefore, in this study, it is attempted to develop a removal-deck plate formwork system for beams by removing deck plates after concrete curing. The system consists of a deck plate module that acts as form, a frame preventing deformation by concrete lateral pressure, stirrup frame, and connector that combines these. As a result of this research, it is verified that it has higher constructability, efficiently prevents deformation caused by concrete lateral pressure and could be easily removed in the developed formwork system.

Flat plate slab is cost-efficient structural system widely used in high rise building, apartment and parking garages. But flat plate-column connections are so weak against punching shear failure that it may cause collapse of overall structure. In this study, spiral type shear reinforcement which increases the shear strength and ductility of the plate-column connection and has good workability was proposed. And experimental test was performed to verify the punching shear capacity of spiral type shear reinforcement. The current code does not accurately estimate the punching shear strength of slab-column connection with shear reinforcement because slab is so slender that punching failure may occurred before shear reinforcement reached yield stress. Therefore modified equation of ACI code for punching shear strength was proposed base on finite element analysis using LUSAS program, and data analysis from CEB-FIP database.

화재 등 재난으로부터의 어린이 안전관리를 기존의 담당기관과 관계자들에게만 맡겨놓고 있을 수는 없다. 국민 각자가 일상 속에서 안전에 대한 의식과 지식, 그리고 정보를 습득하고 유사시에 대응할 수 있도록 안전관리를 체질화하고 생활화해야 한다. 이를 위해 민과 관이 함께 해야 할 활동이 교육 홍보의 차원에서 무엇이 있는지 구체적이고 면밀히 조사연구 하길 바라며 그에 따른 후속 프로그램의 개발 또한 중요하다. 안전문화의 형성을 위한 제대로 된 교육시스템 마련이 중요하다. 관련 교과과정에 안전교육을 의무화하고 집체교육이 가능한 장소에서의 소방.재난 관련 체험 위주의 프로그램을 마련해야 한다. 특히 안전 불감증의 문제는 우리나라만의 문제가 아니다. 다만 '지속성' 과 '계속성' 에 차이가 있을 뿐이다. 우리나라도 '전 생애적 안전관련 프로그램' 을 마련하여 어릴 때부터 조기에 체험할 수 있도록 프로그램을 구성해야 할 것이다. 이와 관련한 관점에서 어린이 안전관련 부처별 업무현황과 추진상황 등을 분석하고 미국 등 선진외국의 어린이 안전사고 방지를 위한 안전교육제도 및 시스템 등의 소개를 통하여 앞으로 민.관 차원에서 현실적인 문제점을 개선할 수 있는 방안을 제시하고자 한다.

현재 소방방재청에서 2009년에 설치 운영중인 DMB재난방송시스템은 지역단위의 재난방송으로 활용을 하지 못하고 광역단위의 재난방송에 활용되고 있는 실정이다. 게릴라성 폭우등 지구 환경의 변화로 인하여 국지적 재난이 빈번히 발생하고 있는 상황에서 광역적인 재난방송 보다는 국지적 재난 상황을 일반 국민에게 신속히 전파하며, 지역에 맞는 대피 방법등을 지역맞춤 재난방송을 전달함으로 재난에 대한 국민의 신뢰도를 높이는 것이 필요하다. 국민들이 가지고 있는 DMB 수신기를 최대한 활용하여 신속하고 정확한 멀티미디어 재난정보 전달체계를 구축하려면 많은 예산과 인력이 필요하다. 이런 문제점을 R&D를 통해 지역에 적합한 정보를 수집하고 방송하면서 중앙재난상황실에 설치된 DMB재난방송시스템을 활용한 지역 재난방송이 가능하도록 전략을 연구하였다.

The statistics of disaster and safety control which have been produced by NEMA(National Emergency Management Agency) and other related agencies have some problems which show redundancies and the lack of connections. These problems can result in disbelief of disaster-management related policies and cause uncertainties on standardization. One of the main problems is caused by the lack of an integrated system that can coordinate available statistical resources. The objectives of this paper are to propose possible ways for the rearrangement of statistics categories, the improvement of statistics indicators and the integration of statistics of disaster and safety management based on the improvement of related laws and regulations. Through the integrated system for an efficient production of disaster and safety-related statistics, it will be possible to establish more accredited disaster-management policies based on the scientific statistics and international standard.

Korean city had been rapid developed through high industrialization and rapid economic growth after the 1970's. The city development process was guaranteed the fulfillment of city function through the city expansion based on New Towns and satellite cities rather than the reformation of existing city. This city expansion caused by degrading of city, being backward and producing many problems. To solve this problems, it was considered the rehabilitation of retarded function with rejuvenation such as a special law accelerating urban renaissance and reorganization project. Also a fire protection performance did not satisfied the required conditions of modern FPP system, such as the function deterioration of building facilities, the technological development with FPP facilities, changed fire laws and building occupancy for social needs. Insufficiency of requirements depreciated the building value and intimidated a safety of residents. To solve this problem, the improvement of FPP was essentially required and also strongly recommended an analysis and a comparative study between the required FPP of existing building and it improving effective FPP. Therefore, purpose of this study is that establish the basic data to construct a system to analyze and compare the building FPP.
