국내 호우 및 태풍으로 인한 홍수피해는 전체 자연재해 피해액 중 90%에 달할 정도로 심각하다. 홍수 피해는 국내의 기후적 특성으로 인해 매년 반복될 뿐만 아니라 최근엔 기후변화로 인해 강우 패턴이 변함에 따라 홍수 대응에 대한 새로운 해결책이 요구되는 상황이다. 이러한 니즈에 맞춰 국내의 홍수 관리 기술 및 제도도 빠르게 발전해왔다. 기술적으로는 수문 관측 밀도, 자료의 축적, 전송, 분석기법 등이 상당한 수준에 이르고 있다. 다만, 단기 강우 예측, 고도화된 홍수해석모형, GIS와의 연계 등이 홍수 예경보 시스템과 실무에 직접적으로 활용되기 위해서는 아직 개발기술에 대한 실용화 연구 및 적용검증이 필요하다. 뿐만 아니라, 제도적으로도 「수자원의 조사·계획 및 관리에 관한 법률 및 시행규칙」을 통해 하천구역 및 그 배후지역에서 홍수로 인명과 재산에 대한 피해가 예상될 경우 홍수 예경보를 실시하도록 하고 있다. 그러나 최근 도달시간이 짧아 홍수선행예보시간이 확보되지 못하는 경우 등이 발생하며 홍수특보 기준에 대한 보완의 필요성이 제기되고 있다. 본 연구에서는 충분한 선행예보시간 확보 및 신속한 홍수대응을 위하여 홍수발생 및 예경보 발령 사례를 분석하고자 한다. 현재 홍수특보 발령 기준은 홍수위험정도에 따라 홍수주의보 또는 홍수경보로 구분하여 발령하도록 하고 있다. 홍수위험정도의 기준은 일반적으로 수위 또는 유량을 기준으로 하고 있으며, 이를 기준수위라고 정의하여 관리하고 있다. 본 연구에서는 홍수특보지점별 사례를 통해 지점의 지형적 특성, 기준수위, 기준수위에 도달시간을 종합적으로 분석하였다. 분석결과를 바탕으로 기존의 홍수특보를 효과적으로 운영하고 홍수피해를 저감하기 위해 고려해야 할 요소를 제시하였다.

The purpose of this study is to investigate the factors that affect the discrimination of low-income children among children in the community children's centers. The subjects of the survey were 6th grade elementary school students who were the third respondents of the second Child Panel Survey of the community children's center, among them, 355 children whose family economy level corresponds to basic living allowance, next level, and blind spot. SPSS Statistics 25.0 was used to analyze exploratory factors, reliability analysis, frequency analysis, descriptive statistics, correlation analysis, and multiple regression analysis. The results of this study showed that single parent family, parent social capital, parental abuse, and happiness had a significant effect on the discrimination damage of low-income children in community children's centers. The more one parent's family, the less the parent's role as a counterpart to the discussion, and the more the parental abuse, the higher the child's discrimination damage. In general, parents-related factors were affecting the discrimination damage of low-income children. Community children's centers and related institutions should focus on developing and implementing programs that can improve the quality of family relations of children.

재해 복구란 국가, 유역은 물론 지구단위 차원에서 개발이 진행 중인 통합적 개발과정으로 추진되어야 한다. 따라서 피해를 입은 기간시설의 단순 재배치나 복원이 아니라 피해지역의 사회, 경제적 조건은 물론 재해 전, 중, 후에 지역사회가 지닌 취약성을 개선하는 기회로 추진되어야 하며 주민들의 신뢰를 회복하고 지속가능한 발전을 추구해야 한다. 국내외 복합피해지역의 복구사례로 강릉시(2002, 태풍 루사), 김천시(2002, 태풍 루사), 미국 뉴올리언스(2005, 허리케인 카트리나)의 피해상황과 복구사업을 대상으로 조사 정리하였다. 복합피해지역의 지구단위 종합복구를 위한 지구별 복구기법은 피해조사, 종합복구계획의 수립, 종합복구계획의 작성 및 복구사업추진으로 순으로 진행할 수 있으며, 복구사업 시행으로 인한 2차 피해의 방지를 위하여 사업 대상지역은 물론 인근지역에 미치는 영향을 분석하여 사업 대상지에 지구단위종합복구기법을 적용할 수 있을 것이다.

본 연구에서는 우리나라에 적합한 재해예측모형을 구축하기 위하여 중해상도(10km)의 입력 자료를 이용하여 태풍에 의해 지상에 발생 가능한 3-second gust를 추정하였다. 중해상도 입력자료의 구축은 경상남도(부산광역시 포함) 시 군 구 단위의 행정구역으로 구분하였으며, 추정된 3-second gust를 이용하여 건물의 주요구성 요소별로 피해 확률을 구한 뒤, 발생 가능한 최대피해액을 산정하였다. 태풍 Maemi에 의한 최대강풍 피해액은 여러 주택유형 중에서도 '대표주택' 유형의 경우 약 6천억 원으로 분석되었다. 비교적 내륙에 위치한 지역에서는 적은 피해액을, 해안가에 위치한 지역에서는 많은 피해액을 나타내며, 부산광역시에서 피해액이 높은 구 군의 경우 경상남도 시 군의 평균적인 피해액과 비슷한 것으로 보아 부산이 경상남도와 비교하여 면적으로는 작지만 태풍에 의한 강풍에 매우 취약함을 알 수 있다.

This study sought to identify developmental trajectories of bullying victimization from late elementary school through early high school, and to examine internalizing and externalizing problem outcomes associated with the trajectory group membership. Data from Seoul Panel Study of Children were collected annually over a 7-year period from 5th grade of elementary school through 2nd grade of high school (2005~2011). Latent class growth analysis yield three trajectory classes corresponding to stable low (81.2%), stable high (3.5%), and declining bullying victimization (15.6%). Findings from analysis of covariance indicated that students in both stable high and declining trajectory groups reported significantly higher means in internalizing behavior (withdrawal, depression/anxiety, and suicide ideation), compared to those in the stable low group. For externalizing behavior such as aggression and juvenile status offense, students in the stable high group showed higher means, compared to those in the stable low and declining trajectory groups. Developmental pattern of bullying victimization over multiple development stages and associated internalizing and externalizing outcomes are discussed as are the implications for the bullying prevention.

With the increase in occurrence frequency and severity of natural disasters due to climate changes arising from global warming, damage in the landscaping field is rising. This leads to legal disputes, and is increasing social and economic damage, too. Especially even though landscape trees which are highly affected by external environments, suffer lots of damage from natural disasters, there is no specific scope of disaster criteria and thus it brings plenty of problems of damage restoration and compensation. Therefore, this study aims to suggest that gives ways to improve related criteria for damage of landscape trees from natural disasters. For this objective, this study analyzed damage cases of landscape trees and precedents, and compared Korean and Japanese legal systems and criteria regarding natural disasters with each other. The analysis result showed that opinions of experts have a great deal of influence on judgment results, since there is no definite legal basis on damage from natural disasters in the landscaping field. This implies the need for a professional and objective appraisal process. According to the comparative analysis of Korean and Japanese legal systems and criteria regarding natural disasters, Korea lacked in laws and criteria on natural disasters of landscape plants in Korea, whereas there were concrete disaster assessment standards of landscape trees in Japan. For improving natural disaster-related systems and criteria in the landscaping field, therefore, this study presented 'Revision of related laws', 'Revision of appraisal and loss assessment criteria', 'Revision of standard specification of landscaping project', 'Compulsory insuring against disasters', 'Reasonable fulfillment of contract', and 'Compulsory cost estimation for disaster restoration', as improvement plans.

In this study, we presented a method for estimating the potential population damage of the Seoul Nowon-gu area in the event of a terrorist using a vehicle improvised explosive devices (IED). Using the object-based building extraction method with orthophoto image, the area of the apartment has been determined, and the apartment's height and level were estimated based on the elevation data. Using the population estimation method based on total floor area of building, each apartment resident population was estimated, and then potential population damage at the time of terrorist attacks was estimated around the subway station through a scenario analysis. Terrorism damage using IED depends on the type of vehicle greatly because of the amount loadable explosives. Therefore, potential population damage was calculated based on the type of vehicle. In the results, the maximum potential damage population during terrorist attacks has been estimated to occur around Madeul station, Nowon-gu. The method used in this study can be used various population estimation research and disaster damage estimation.
