In order to reduce flood damage with debris flow, it is necessary to build up comprehensive flood control, including structural and non-structural countermeasures. In this paper, the decision making factors of individual refuge activities which are major non-structural activities to save peoples, lives against flood have been estimated based on questionnaire survey. Furthermore, in order to effective debris flow countermeasures, its simulation has carried out and it will useful for minimizing their damages.

최근 들어 정보윤리의 폐해로 인한 법적인 대응이나 기술적인 대응들이 한계에 부딪치면서 보다 교육적인 대응이 강조되고 있다. 특히나 인터넷 게임 중독이 갈수록 저 연령화되어 가고 있는 시점에서 초등학교 저학년들을 위한 인터넷 게임 중독 진단과 그에 따른 처방을 제공하는 콘텐츠가 필요해졌다. 본 논문의 초등학교 저학년을 대상으로 한 인터넷 게임 중독 콘텐츠가 의도대로 활용된다면 정보화 사회를 살아가는 사회 구성으로서 갖추어야 할 올바른 가치관과 행동양식을 심어주게 될 것이다.

재난에 대비하여 각 기관에서는 자체의 위기관리 매뉴얼을 보유하고 있고, 이를 기반으로 재난대응 훈련 등을 실시하고 있다. 그러나 이러한 매뉴얼은 개념적이어서 재난 발생 시 현장에서 즉각적으로 수행하기에는 구체성이 부족하다. 본 연구는 이러한 관점에서 위기관리 매뉴얼을 SOP 기반의 시스템으로 변환하여 운영할 수 있는 플랫폼 기술을 개발하는데 있다. 플랫폼은 단위 행동 모임인 SOP 관리 모듈, 위기관리 매뉴얼 기반 재난 대응 절차를 수행을 위한 시나리오 관리 모듈, 그리고 기관의 담당자가 직접 해당 SOP를 수행하기 위한 정보인 조직도 관리 모듈로 구성되어 있으며, 실제 재난 대응을 통하여 수행한 활동에 대한 정보를 기록하여 빅 데이터를 분석하여 보완할 수 있는 기반을 마련하였다.

사용자-객체 상호작용을 위해서는 영상 내 객체의 종류와 위치를 정확하게 파악하여 사용자가 객체에 관련된 행동을 취할 경우, 그에 맞는 상호작용을 수행해야 한다. 이러한 객체인식에 널리 사용되는 지역 불변 특징량 기반의 방법론은 복잡한 배경이나 균일 물체에 대하여 잘못된 매칭으로 인식률이 저하된다. 본고에서는 이를 해결하기 위해, 컬러와 깊이 근접도 기반 깊이 계층을 나누고, 복잡 배경으로부터 생기는 잘못된 특징점 대응을 최소화 하기 위해 각 깊이 계층과 인식 물체 영상간의 특징점 대응을 수행한다. 또한, 각 깊이 계층영역에서 색상 히스토그램 재투영으로 객체의 위치를 추정하고 추정 영역과 인식 물체 영상간의 생상 및 깊이 유사도를 판단한다. 최종적으로, 복잡 배경 효과를 최소화한 특징점 대응의 수, 색상 및 컬러 유사도를 고려하여 신뢰도를 측정하여 객체를 인식하게 되며, 이를 통해 복잡한 배경에서도 사용자와 객체간의 유연한 상호작용이 가능해진다.

Every year, the complexity and scale of disasters are growing. Cooperation between institutions must occur in order to adequately respond to urgent situations caused by these disasters. However, agencies and institutions tend to operate separately, which impose limitations to an integrated disaster response. To combat this problem, the subject of this study: 'Korean standardized integrated response system For disaster site' proposes to develop a response system that is applicable to disasters of all types and scales. Standard Formation, SOP (Standard Operation Procedure), and Standard Terms have been developed to be applicable to various institutions and agencies. The necessity for legal and institutional support to actualize the standardized system is focused on. Utilizing a standardized integrated response system will enable a unified command and control structure at disaster sites, clarify each institution's response tasks, and allow clear and efficient communication among response entities. Ultimately, these benefits will improve efficiency and performance in disaster response efforts.

Purpose: Earthquake disasters are frequently occur unpredictable situations due to various variables and unexpected situations. As a result, the work process itself is not uniform, making it difficult for public officials in the disaster safety department to familiarize themselves with the earthquake field manual. This paper is specifically and accurately grasp the current work situation conducted by the Disaster and Safety Countermeasures Headquarters of the Gyeongsangbuk-do Office and present a plan for designing serious game scenarios necessary for field manual learning. Method: In this study, scenarios were designed based on the GBS(Goal Based Scenario) model, and in the process of assigning missions and roles based on the Gyeongsangbuk-do earthquake field manual, public officials related to earthquakes were able to acquire knowledge and skills to solve practical tasks. Result: Scenario data of the proposed technique was implemented as a systematic procedure by processing various earthquake-related information into logical data and simplifying and abstracting it for game expression for earthquake situation training. Conclusion: In the event of an earthquake due to learning through serious games, related public officials of Gyeongsangbuk-do provincial are expected to be able to respond quickly to various earthquake disasters.

The purpose of this study is to supply basic marketing information and establish marketing strategy on local market by analyzing related using behavior of lifestyle type and buying behaviour of local residents. On this viewpoint, we focused on identifying the lifestyle, shopping behaviour, and media usage pattern. For this research, we surveyed consumers living in Jecheon city and analyzed questionnaires by multivariate statistical analysis. Through empirical analysis, we derived overall lifestyle profiles including demographic traits, media usage, leisure pattern in each lifestyle types and marketing implications.

The purpose of this study was to examine the effects of a script intervention based on multimedia on the verbal and behavioral self-advocacy skill of elementary school students with disabilities. A multiple probe baseline design across subjects had been used with 4 students with intellectual disabilities. The results showed all participants showed significant increase of verbal and behavioral self-advocacy performance in asking for help, expressing one's opinions, and coping with violations, and the effects were maintained. The intervention was more effective for verbal self-advocacy than behavioral. Some suggestions for future study are discussed.

Recently, cyber attacks against public communications networks are getting more complicated and varied. Moreover, in some cases, one country could make systematic attacks at a national level against another country to steal its confidential information and intellectual property. Therefore, the issue of cyber attacks is now regarded as a new major threat to national security. The conventional way of operating individual information security systems such as IDS and IPS may not be sufficient to cope with those attacks committed by highly-motivated attackers with significant resources. In this paper, we discuss the technologies and standard trends about actual cyber threat and response methods, design the collaborative response framework based on the security information sharing in the inter-domain environments. The computation method of network threat level based on the collaborative response framework is proposed. The network threats are be quickly detected and real-time response can be executed using the proposed computation method.
