이 연구는 우리나라 국가위기관리체계의 문제점을 분석하여 발전방안을 제시하는데 목적이 있다. 이를 위해 위기, 위기관리의 개념과 국가위기관리 조직체계, 국가위기관리 조직관련 법령 등을 살펴보았다. 우리나라의 국가위기관리 개념은 위기와 안전, 보안, 위험, 재난 등의 개념이 혼재된 가운데 용어가 혼용되어 사용되고 있다. 게다가 개별적으로 발전해온 법령으로 인하여 국가위기관리 조직은 분야별로 분산되고, 각각의 조직 운영으로 중복되어 효율성이 제한되며, 한정된 국가위기관리 자원이 비효율적으로 운용되고 있다. 결국 개별 법령에 규정된 다수의 국가위기관리 조직을 효율적으로 통합 관리하는 데에는 법체계상 한계가 있으며, 컨트롤 타워가 미흡한 가운데 관련부처간의 조정 통제가 곤란한 실태에 있다. 이에 따라 이 연구에서는 개념의 불명확성에 대한 문제점의 발전방안으로 위기의 개념을 명확히 하고, 조직과 법령이 분산된 문제점에 대해서는 국가 통합위기관리체계(IEMS)를 제시하였다. 이를 통하여 궁극적으로는 한국의 국가위기관리체계의 발전을 위한 조직적 법적 통합방안을 제시하였다.

In-situ production of PC (precast concrete) members can reduce costs by about 14.5% -21.6% compared to in-plant production due to the reduction of transportation costs, factory profits and overhead costs. However, in-situ production of PC members presents a variety of risks, including member production and yard area securing, and lead time for production within the installation period. To solve this, it is necessary be able to analyze and control and monitor the risk factors that influence in-situ production for PC member. The purpose of this study is to develop a dynamic simulation model for in-situ production and erection integrated management for PC members. For this study, risk factor identification, causal loop diagram, and dynamic simulation model construction were performed sequentially. The results of this study will be used as a basis for developing a risk management model for PC in-situ production.

Although Korea coastal area has the increasing potential marine accident due to frequent ship's encounter, increased vessel traffic and large vessel, there is no specific model to evaluate the navigating vessel's risk considering the domestic traffic situation. The maritime transport environmental assessment is necessary due to the amended maritime traffic law. However, marine safety diagnosis is now carried out by foreign model. In this paper, therefore, we suggest a domestic traffic model reflecting the characteristics of korea coastal area and navigator's risk as we named PARK(Potential Assessment of Risk) model. We can evaluate the subjective risk by establishing the model and model output into maritime risk exposure system. To evaluate this model's effectiveness, we used ship handling simulation and applied, analyzed collision accident which occurred in korea coastal area. And also, we applied integrated to an ECDIS program for monitoring traffic risk of vessels with real time based AIS data and apply to evaluate traffic risk in busan harbor waterway. As a result, we could evaluate busan harbor waterway risk effectively.

The railway safety in Koreaisthreatenedduetotherestructuring of the railway industries, introduction of the Korea Train eXpress (KTX) and electrification of the conventional lines. Many technical backgrounds are required to control railway accidents as low as reasonably practicable, such as a railway safety act, safety standards, and safety assessment infrastructures. Korean government and the Korea Railroad Research Institute (KRRI) are conducting an integrated R&D program for improvement of the railway safety, where the target is to reduce the accident fatalities by half. The program is composed of three parts; the safety system engineering and the program management, the establishment of a safety management system, and the development of techniques for assessing and preventing major railway accidents. Details of the research programs are explained in this paper, where risk is used as the major control measure.

Recent updates in genomic-integrated glioma classification have caused confusion in current clinical practice, as management protocols and health insurance systems are based on evidence from previous diagnostic classifications. The Korean Brain Tumor Society conducted an electronic questionnaire for society members, asking for their ideas on risk group categorization and preferred treatment for each individual diagnosis listed in the new World Health Organization (WHO) classification of gliomas. Additionally, the current off-label drug use (OLDU) protocols for glioma management approved by the Health Insurance Review and Assessment Service (HIRA) in Korea were investigated. A total of 24 responses were collected from 20 major institutes in Korea. A consensus was reached on the dichotomic definition of risk groups for glioma prognosis, using age, performance status, and extent of resection. In selecting management protocols, there was general consistency in decisions according to the WHO grade and the risk group, regardless of the individual diagnosis. As of December 2022, there were 22 OLDU protocols available for the management of gliomas in Korea. The consensus and available options described in this report will be temporarily helpful until there is an accumulation of evidence for effective management under the new classification system for gliomas.

태양광 발전소는 전기를 생산하는 시설물로써 화재와 감전 사고의 위험이 설치장소의 다변화로 근무자와 주변인, 시설물에 대한 위험도가 증가하여 안전사고를 예방하고 안전사고 발생에 따른 빠른 대처를 할 수 있는 시스템을 개발이 대두되고 있다. 위와 같은 개발에 필요성을 비추어 볼 때 태양광발전 시스템에서 생산되는 데이터를 취합, 분석하는 기술을 개발하여 발전시스템의 문제를 실시간으로 진단하고 유지/보수할 수 있는 태양광발전 관리시스템을 개발하여야 하고 이를 통해 이용률 증가 및 유지보수 비용이 감소하는 효과를 볼 수 있다. 이를 위해서는 우선적으로 현재의 상태에서 태양광 발전량을 정확히 예측하여, 현 발전상태의 이상 유/무를 진단 및 이상 위치를 파악하여야 하고 이상 위치가 파악되면 경제성이 고려된 모델을 이용하여 수리/교체의 필요성, 시기 등의 정보가 제공되어야 한다.

In this study, the scope of previous logistics security were focused only on port and ship. Because of it now extends to the overall (export and import) supply chain areas and in regards with supply security programs in the international level, it reviewed supply chain security programs categorized them into 'ships and port security system', 'container screening system', 'logistics chain authorization system' which are expanded to be adopted in the international level. The major features of those programs are summarized as in building risk management system, providing information ahead, selectivity test and benefits to AEO authorized companies in the customs administration level. The government and companies which are to ensure supply chain security and trade facilitation in order to cope actively with international customs administrative atmosphere need to do the followings : First, they need to build an intra-government integrated supply chain security and make efforts to conclude AEO MRA in order to increase trade competitiveness among major trading countries. Second, they need to build supply chain risk management system in order to enhance management performance through overseas market and company level strategy to obtain and maintain AEO authorization in the company level.

The emergency response modeling system CARIS has been developed at CCSM (Center for Chemical Safety Management), NIER (National Institute of Environmental Research) to track and predict dispersion of hazardous chemicals for the environmental decision support in case of accidents at chemical or petroleum companies in Korea. The main objective of CARIS is to support making decision by rapidly providing the key information on the efficient emergency response of hazardous chemical accidents for effective approaches to risk management. In particular, the integrated modeling system in CARIS consisting of a real-time numerical weather forecasting model and air pollution dispersion model is supplemented for the diffusion forecasts of hazardous chemicals, covering a wide range of scales and applications for atmospheric information. In this paper, we introduced the overview of components of CARIS and described the operational modeling system and its configurations of coupling/integration in CARIS. Some examples of the operational modeling system is presented and discussed for the real-time risk assessments of hazardous chemicals.
