최근 세계 곳곳에서 사회 이면에 도사린 위험요소가 재해로 연결되면서 수많은 재산/인명 피해를 끼치는데 그치지 않고 심각한 사회문제로 대두 되고 있다. 특히 우리나라는 비약적인 경제발전의 결과로 도시화가 빠르게 이루어지고, 경제의 규모도 커지면서, 여러 인적/사회적 재난을 반복적으로 경험하는 악순환에 빠져있다. 이런 심각성 때문에 오랜 시간동안 재난을 관리하기 위한 다양한 분야의 연구가 지속되었으며 학문의 영역 또한 빠르게 복합화 되면서 확장 되고 있다. 본 연구는 재난과 방재측면에서 그간의 연구방향 이었던 방재학적, 방재공학적, 사회학적 관점에서 벗어나 서비스디자인 관점으로 접근함으로서 대안적 연구를 시도 하였다. 그 과정에서 재난과, 서비스디자인에 대한 개괄을 알아보고 방재 프로젝트에 적용함으로서 효과적이고 실질적인 방재서비스디자인을 정의하고 논의 하고자 하였다. 이는 구체적인 사례를 통해 연구 방법론을 적용 검증함으로서 교과서적인 논의에서 벗어나 실 적용측면에서의 논의를 진행 하고자 하는 목적으로 진행되었다. 연구 결과로 도출된 방재서비스 디자인 프로세스와 플랫폼을 통해 방재서비스디자인을 정의 하고 이해할 수 있을 것으로 기대된다. 또한 방재서비스디자인을 통해 재난의 전후 전 단계에서 재난과 관련된 유/무형의 여러 요소를 디자인적으로 가시화시킬 수 있게 되는 기초자료가 될 수 있을 것으로 기대 된다.

The vast majority of the disaster prevention design research in Korea has focused on the macro-level interventions such as examining the existing systems and approaches, instituting revised policies, systematically establishing intervention programs, and evaluating the effectiveness of the interventions. However, little has focused on systematically challenging individuals' awareness using micro-level intervention. The present paper introduces approaches to micro-level intervention by infusing narrative-based simulation, and further suggests the implications on balancing the approaches of both micro-level and macro-level interventions.

어린이 보호구역은 교통사고의 위험으로부터 어린이를 보호하기 위해 학교, 보육시설, 학원 등과 같은 시설 가운데 지정된 일정 구간을 말한다. 어린이 보호구역은 1995년 9월 제정된 이래, 2021년 1월까지 총 9번의 개정을 통해 강화가 됐음에도 어린이 보호구역 사고는 줄어들지 않고 있다. 본 논문은 방재디자인 기반의 어린이 보호구역 표준모델을 제시하고자 하였다. 연구의 방법으로는 문헌조사, 실증조사, 인식도 조사를 진행했다. 인식도 조사 대상은 어린이, 학부모, 운전자를 대상으로 조사를 진행하였다. 환경 조사 대상으로는 횡단보도, 자동차도로, 보행자도로, 신호등을 대상으로 조사하였다. 조사 결과 차량 운전자의 어린이 보호구역 시각적 인지가 어렵다는 점이 발견되었고, 보행자 도로를 이용하는 오토바이가 어린이에게 매우 위협적인 요소로 다가왔음을 알게 되었다. 이에 따라 방재디자인 중심의 개선된 어린이 보호구역 표준모델 디자인을 제시하였다.

This paper presents optimization of a long-span portal steel frame under dynamic wind loads using a surrogate-assisted evolutionary algorithm. Long-span portal steel frames are often used in low-rise industrial and commercial buildings. The structure needs be able to resist the wind loads, and at the same time it should be as light as possible in order to be cost-effective. In this work, numerical model of a portal steel frame is constructed using structural analysis program (SAP2000), with the web-heights at five locations of I-sections of the columns and rafters as the decision variables. In order to evaluate the performance of a given design under dynamic wind loading, the equivalent static wind load (ESWL) is obtained from a database of wind pressures measured in wind tunnel tests. A modified formulation of the problem compared to the one available in the literature is also presented, considering additional design constraints for practicality. Evolutionary algorithms (EA) are often used to solve such non-linear, black-box problems, but when each design evaluation is computationally expensive (e.g., in this case a SAP2000 simulation), the time taken for optimization using EAs becomes untenable. To overcome this challenge, we employ a surrogate-assisted evolutionary algorithm (SAEA) to expedite the convergence towards the optimum design. The presented SAEA uses multiple spatially distributed surrogate models to approximate the simulations more accurately in lieu of commonly used single global surrogate models. Through rigorous numerical experiments, improvements in results and time savings obtained using SAEA over EA are demonstrated.

Flat or Multiple Dwelling Houses are relatively vulnerable to crime safety. Crime prevention measures are urgently needed because crime is 2.6 times higher than in real apartments. Through the analysis of domestic and foreign crime prevention design standards, field survey, and interviews with experts, 27 items of crime prevention design criteria for flat or multiple dwelling house were derived, and ten design criteria that should be considered first by the expert AHP were derived. As a result of the pilot evaluation of existing flat or multiple dwelling house, the houses completed after 2015 have relatively high level of crime prevention, but the houses constructed before that are very vulnerable. The policy and system improvement plan based on the analysis result is as follows. First, new housing should be promoted to meet minimum criteria by supplying and educating public officials, architects, and building owners in the short term to provide criteria for flat or multiple dwelling house crime prevention plans. Second, existing housing should be supported with basic crime prevention support projects such as security windows for flat or multiple dwelling house where security of residential environment such as urban renewal policy is poor. Third, the Enforcement Decree of the Building Act shall be revised to make the crime prevention environment design of flat or multiple dwelling house obligatory, and the criteria of flat or multiple dwelling house crime prevention plan should be reflected in the notice of crime prevention building standard.

The national long-term R&D program, updated in 1997, requires Korea Atomic Energy Research Institute(KAERI) to complete by the year 2006 the basic design of Korea Advanced Liquid Metal Reactor(KALIMER), along with supporting R&D work, with the capability of resolving the issue of spent fuel storage as well as with significantly enhanced safety. KALIMER is a 150 MWe pool-type sodium cooled prototype reactor that uses metallic fuel. The conceptual design is currently under way to establish a self-consistent design meeting a set of major safety design requirements for accident prevention. Some of the current emphasis includes those for inherent and passive means of negative reactivity insertion and decay heat removal, high shutdown reliability, prevention of and protection from sodium chemical reaction, and high seismic margin, among others. All of these requirements affect the reactor design significantly and involve extensive supporting R&D programs. This paper summarizes some of the results of conceptual engineering and design analyses performed for the safety of HAMMER in the area of inherent safety, passive decay heat removal, sodium water reaction, and seismic isolation.

Purpose: This study was done to develop and test the effectiveness in late school-aged children of a healthy lifestyle education program for cancer prevention. Methods: Participants were 26 students in the sixth grade of N elementary school in J City (experimental group) and 25 students in the sixth grade of D elementary school with same educational conditions (control group). The research design was a nonequivalent control group pretest-posttest design. Data collection and execution of the study were carried out from March 10 to May 19, 2011. For the experimental treatment, 7 weekly sessions of the healthy lifestyle education program for cancer prevention were given by the researcher. Posttest was done immediately following the conclusion of the program and 4 weeks later. Frequencies, percentages, ${\chi}^2$-test, t-test, repeated measures ANOVA and paired t-test with SPSS WIN 18.0 were used to analyze the data. Results: Perceived barriers, perceived self-efficacy, activity related effect and family support significantly influenced cancer prevention knowledge and increases in healthy life styles. Conclusion: Results indicate that, as this program for cancer prevention was effective in increasing healthy lifestyle practices in these children, there is a need to further develop, test and implement programs in all schools.

Smart home systems for safety and security are in high demand and always needed for many reasons including people's desire to feel safe in their own houses and to avoid a high rate of crime. In the current research, we investigate the role of individuals' motivational orientation to prevention in their responses to smart home systems for safety and security. That is, this research examines whether individuals' attitudes toward smart home systems for safety and security vary depending on their level of prevention orientation. Specifically, it is hypothesized that individuals with strong (vs. weak) prevention orientation will have more positive attitudes toward smart home systems for safety and security. In support of the hypothesis, the results indicate that respondents in the strong (vs. weak) prevention orientation reported significantly more positive attitudes toward smart home systems for safety and security. Our findings imply that individuals' motivational orientation to prevention may be an effective marketing and segmentation tool in facilitating their favorable responses to the smart home systems for safety and security.
