  • 가뭄은 전 지구차원의 다방면에 걸쳐 피해를 주는 자연 재해이다. 21세기 들어 최근까지 다양한 위성관측 기기를 활용하여 다양한 가뭄의 유형을 모니터링 할 수 있게 되었는데, SMAP위성의 토양수분, GRACE 위성의 생태계 물 저장량, Terra & Aqua의 생태계 생산량과 증발산량 그리고 위성 강우 관측 등이 그 예이다. 이들 위성 자료의 분석을 통해 지역적 수자원 현황 및 가뭄과 이로 인한 (수)생태계 영향, 농업 등의 산업, 그리고 인간사회의 영향을 시공간적으로 파악할 수 있다. 가시광선부터 마이크로파까지 채널 (밴드)마다 관측할 수 있는 기상 및 환경 변수가 다르기 때문에 다양한 센서로부터 획득할 수 있는 원격탐사자료는 한반도 전역을 대상으로 가뭄에 대한 수자원 변화와 연관된 피해를 시공간적으로 파악하는 데에 상호 보완적이며 효과적인 수단이다. 따라서 이러한 위성자료들을 통해 국가 재난 대응 차원의 활용방안을 제안하고자 한다.

  • 본 연구는 상주해빈의 침식현상을 진단하기 위하여 해빈 단면 측량결과 및 저질 조사결과를 기초로 하여 해빈의 천이주행 특성 및 각 단면별 저류표사량을 산정 하여 해빈 보호 대책을 수립하기 위한 기초자료를 제시하고자 한다. 현장관측을 통하여 상주해빈에 침식방지의 기능을 도모하고자 설치한 돌제가 역기능을 나타내고 있음을 알 수 있었다. 이러한 이유는 도류제가 건설된 후 침식이 가속화되어 침식방지의 기능을 위하여 설치한 돌제가 침식방지의 기능보다는 침식을 가속화시키는 것으로 조사되었다. 그리고 Sonu and Beek(1971)가 제시한 해수면상 저류표사량 산정모델이 자연해빈뿐만이 아니라 해안 구조물이 설치된 해빈에도 유용한 모델임을 입증하였다.

  • The Asian summer monsoon has a profound social and economic impact in East Asia and its surrounding countries. The monsoon is basically a response of the atmosphere to the differential heating between the land mass of the Asian continent and the adjacent oceans. The atmospheric response, however, is quite complicated due to the interactions between the atmospheric heat sources, land-sea contrast, and topography, The occurrence of extreme summertime floods in Korea, Japan, and China in 1998 and 1999 has highlighted the range of variability of the East Asian summertime monsoon circulation and spurred interest in investigating the cause of such extreme variability. While ENSO is often considered a prime mechanism responsible for the unusual hydrological disasters in East Asia, understanding of the connection between ENSO and the East Asian monsoon is hampered by their dynamic complexities. Along with a recent phenomenon of weather abnormalities observed in many parts of the globe, Korea has seen its share of increased weather abnormalities such as the record-breaking heavy rainfalls due to a series of flash floods in the summers of 1998 and 1999, following devastating Yangtze river floods in China. A clear regime shift is found in the tropospheric mean temperature in the northern hemisphere middle latitudes and the surface temperature over the Asian continent during the summer with a sudden warming since 1977. Either decadal climate variation or climate regime shift in the Asian continent is evident and may have altered the characteristics of the East Asian summer monsoon. Considering the summertime rainfall amount in Korea is overall increased lately, the 1998/99 heavy rainfalls may not be isolated episodes related only to ENSO, but could be a part of long-term climate variation. The record-breaking heavy summer rainfalls in Korea may not be direct impact of ENSO. Instead, the effects of decadal climate variation and ENSO may be coupled to each other and also to the East Asian summer monsoon system, while their individual impacts are difficult to separate.

  • Drought events are not clear when those start and end compared with other natural disasters. Because drought events have different timing and severity of damage depending on the region, various studies are being conducted using satellite images to identify regional drought occurrence differences. In this study, we investigated the applicability of drought assessment using the Evaporative Stress Index (ESI) based on Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images. The ESI is an indicator of agricultural drought that describes anomalies in actual and reference evapotranspiration (ET) ratios that are retrieved using remotely sensed inputs of Land Surface Temperature (LST) and Leaf Area Index (LAI). However, these approaches have a limited spatial resolution when mapping detailed vegetation stress caused by drought, and drought hazard in the actual crop cultivation areas due to the small crop cultivation in South Korea. For these reasons, the development of a drought index that provides detailed higher resolution ESI, a 500 m resolution image is essential to improve the country's drought monitoring capabilities. The newly calculated ESI was verified through the existing 5 km resolution ESI and historical records for drought impacts. This study evaluates the performance of the recently developed 500 m resolution ESI for severe and extreme drought events that occurred in South Korea in 2001, 2009, 2014, and 2017. As a result, the two ES Is showed high correlation and tendency using Receiver Operating Characteristics (ROC) analysis. In addition, it will provide the necessary information on the spatial resolution to evaluate regional drought hazard assessment and and the small-scale cultivation area across South Korea.

  • Due to various industrial accident that occur to the staff in the broadcasting production sites, the issue of safety at the broadcast production site is becoming a social issue. Nevertheless, not many researches have been carried out on the actual conditions of the staff's production environment and its safety issues. Therefore, the purpose of this study was to prepare a countermeasure based on engineering knowledge by analyzing working environment to improve the poor working environment of staff. First, this study analyzed statistical data of industrial accidents over the past five years to find out the current status of disasters at broadcasting production sites. As a result, the intensity of the accident was not weak in that the loss days was more than one month in 85% of accident. In addition, the type of accident was high in the fall/trip accidents. Second, this study visited 10 broadcasting production sites for risk assessment. By analyzing the characteristics of the working environment and 104 questionnaires, we predicted the types of accidents that can occur in the broadcasting production site. As a result, accident types such as fall, collision, and trip were relatively high, similar to the characteristics of construction site. Third, it was possible to quantify the scale of the risk in the broadcasting production, and as a result, the quantity of temporary structure and accident risk were proportional. In other words, this study analyzes broadcasting work environment and defines risk factors based on safety engineering knowledge. Finally, this study suggested a guideline to improve the safety of the broadcasting production site.

  • Objectives Children are one of the most vulnerable populations to the impact of disasters. We aimed to examine children's mental health in the area affected by the Hebei Spirit oil spill accident on December 7, 2007. Methods A cross-sectional questionnaire survey was conducted using the Korean versions of the Children's Depression Inventory and State Anxiety Inventory for Children on 1,362 children attending elementary schools in the affected area. The information on distances between the nearest contaminated coastline to the child's residential house or attending school were obtained using a web-based map by inputting two address points. The symptom risks of depression and state anxiety were estimated by multiple logistic regression analyses adjusted for age, gender, and other covariates. Results Children with the closest distance (in the fourth quartile) to the school from the contaminated coastline showed a significantly higher symptom risk of depression compared to those with the farthest distance (first quartile)(odds ratio, 2.73; 95% confidence interval, 1.40-5.33), while there was no significant association between anxiety symptoms and distance. Conclusions Children, a vulnerable population for mental health impact by the oil spill accident, should be included in mental health programs in the community along with their family as victims of the disaster.

  • A traditional village is cultural property where old buildings and traditions are concentrated and also where indigenous traditional cultures can be recognized and experienced directly or indirectly. In addition, traditional villages have been recognized as precious resources to revitalize regional economies through tourism. Currently, signage systems have been developed as for ordinary tourist sites or cities, and concepts or methods for sign system for traditional villages have not yet been established. Therefore, it is necessary to develop disaster prevention-based signage to prevent large-scale disasters, to guarantee the safety of residents, and to increase the satisfaction of visitors in traditional villages as precious resources. A case study is conducted to apply the proposed sign system for traditional villages in Korea and Japan as a tourist-oriented sign system that has been accomplished in Korea and a large disaster-oriented sign system developed with residents as a priority in Japan. The disaster prevention sign system considers the residents since residents are victims when a disaster happens, and guideline to increase the efficacy and satisfaction are suggested. However, this study has definite limits in sucring objectivity because the objects of study are insufficient, and the development of the sign system based on effective disaster prevention considering the features of traditional villages will continue in the future.

  • 지구온난화 및 기후 변화에 따른 재난, 이상기온, 질병 등 각종 사회 문제들이 대두됨에 따라, 에너지 절감 및 효율화를 위한 기술 개발이 증대되고 있다. 주택, 상업건물, 공공 건물 분야에서 소비되는 에너지는 우리나라 전체 에너지 사용의 22%를 차지함에 따라, 건물에너지 절감은 전체 에너지 절감에서 매우 중요한 요소이며, 이를 위한 방안이 추진되고 있다. 기존의 건물에서는 에너지 효율화를 위해 열 손실에 대한 대책 마련 및 에너지 저소비형 장비 사용 등의 수동적 방법을 사용하였으나, 최근에는 ICT 기술과 융합하여 에너지 사용의 측정, 모니터링, 통제를 통해 지속적으로 에너지 낭비 요소를 감지 및 제거하는 방식의 건물 에너지 효율화를 위한 능동적 기술이 대두되고 있다. 에너지 효율화를 이용하여 에너지 절감 장비를 사용하더라도, 낭비 상황을 제어하지 않으면 실질적이고 지속적인 에너지 절감 효과를 달성하기 어렵게 된다. 이 논문에서는 국내외 건물 에너지 효율화를 위한 기술 개발 현황을 소개하고, 능동적 에너지 절감을 위한 이슈를 고찰한다.

  • The government separated and established the industrial safety and health law from the Labor Standard law since 1981 to promote the labor's working environment and to improve the conditions of laborers. The government made a lot of effort to discharge the industrial safety and health law by continuous revision of the law thereafter. it is, however, difficult to establish clear-cut lines of authority and responsibility due to the fact that the substantial application of the industrial safety and health law is adapted by enterprise's autonomous management. There are frequent industrial disasters on the small and medium enterprises which have financial difficulty and it means this causes much more social cost. Finally, for the improvement of laborer's safety, health and working environment in the small and medium enterprises we need to raise the effectiveness of the industrial safety and health law through enhancing a government-office's administration and surveillance with the changing mind of a business proprietor. On this paper, we research on the actual condition of the administration, inspection and regulation of safety and health by means of the industrial safety and health law. Thereafter we analyze how much the Korea Occupational Safety & Health Agency and vicarious businesses of safety & health management help. we used the survey method to gather data from 380 laborers directly and analysed the data by SPSS v17.0.
