The risk analysis's aim is analyze the risk for the asset of organization with asset assessment, vulnerability assessment, threat assessment. existing TTA risk analysis methodology model propose to overall flow, but can not propose to detail behavior or each level. That is, step of risk analysis is insufficient in classification of threat and detail proposal of considered the risk with classified threat. So this paper propose that analysis and evaluate the vulnerability and threat assessment with determinated quantity. this paper consider current national information system and threat of environment and technology. So can estimate the risk with determinated quantity. Finally, analyze the asset risk of organization.

Many countries are managing the transportation of hazardous materials under the specific provisions especially, as well as use, storage and management, because of their high risks. For the purpose of the revision of rail safety law for the safe transportation of hazardous materials, amount and kind of hazardous materials transported by rail in Korea are analysed and the standards of classification of hazardous materials are compared in domestic and abroad. There are lots of benefits for national rail safety law to implement an international law because our country's geographic location is convenient to connect the continent and to across the border. It is suggested that implementing a classification and test methods of hazardous materials enable to use internationally for the preparation of rail transportation to be increased.

GHS는 화학물질의 분류 표시에 대한 세계조화시스템(Globally Harmonized System of Classification and Labelling of Chemicals)으로 동일한 화학물질에 대해 국제적으로 동일한 유해 위험성 분류 표시를 하기 위한 새로운 규정이다. 화학물질의 분류 표시는 화학물질이 갖는 여러 가지 유해성, 위험성을 적절히 판별하고, 그 정도에 따라 분류한 다음, 가장 이해하기 쉬운 형태로 표시하는 것이 그 목적이며 올바른 정보제공을 통한 안전관리를 강화하고 국제적인 조화를 통하여 화학물질의 적정 평가 및 국제적 교역을 증대하고자 하는데 있다. 본 고에서는 유독물 등의 분류기준 및 표시방법에 관한 규정과 유독물의 표시규격에 대해 살펴보도록 한다.

해양수산부(장관 윤진숙)는 위험물의 분류기준을 국제기준과 동일하게 적용하고 위험물질 운송에 따른 안전성 제고를 위해 "위험물 선박운송 기준"을 개정하여 시행한다고 밝혔다. 개정된 기준은 국제적으로 적용되는 "국제해상위험물규칙"(IMDG Code)의 최근 개정내용을 반영하고, 위험물 및 화물구역의 종류별 방화장치 요건을 강화하여 위험화물로 인한 선박의 화재 및 폭발 사고가 감소될 것으로 기대된다. 특히, 위험물 운송 용기를 용기의 종류, 재료 및 형태별로 구분하고 외관, 구조 및 성능검사로 세분하여 위험물 용기 검사체계를 효율화함으로써 민원인의 편의를 도모하였으며, 또한, 국제기준에 따라 자동차를 일반선박이나 컨테이너에 수납하여 운반하는 경우 위험물로 분류되어 위험물수납 검사대상이 된다. 본 고에서는 "위험물 선박운송 기준" 일부 개정(안)에 대해 살펴보도록 한다.

In this study, risk categorized five safety management elements(equipment and structure, evacuation, lifesaving and fire extinguishing, performance based fire safety plan, operations management) were classified in order to establish safety system of underground space. Using classified safety management elements, assessment of fire hazard was performed. After calculating the grade of evaluation categories, assessment of fire hazard was suggested. The three grades of evaluation categories are classified as to importance and four criteria of evaluation are classified as to check result based on subdivisions.

우리나라는 매년 집중호우로 인한 산사태로 인해 인적, 물질적 피해를 일으킨다. 반복적인 산사태의 피해를 방지 하기위해서는 산사태 예측 시스템이 필요하다. 본 연구에서는 안성시를 대상으로 GIS와 RS 자료를 활용하여 산사태 위험지를 분석하고자 Logistic 회귀분석 방법과 AHP 기법을 이용하였다. Logistic 회귀분석과 AHP 기법에는 6개의 인자(경사, 경사향, 고도, 토양배수, 토심, 토지이용)를 사용하여, 7등급으로 산사태 위험도를 분류하였다. Logistic 회귀분석 방법과 AHP 기법을 이용한 산사태 위험지도를 표본 자료와 비교하면 산사태가 발생한 표본에서 산사태 위험성이 높은(1-2등급)지역이 Logistic 회귀분석에서는 46.1% AHP 기법은 48.7%로 분류되어 AHP 기법이 분류도가 높다고 분석 되었다. 하지만 Logistic 회귀분석과 AHP 기법은 서로 분석 과정의 차이를 가지고 있기 때문에 Logistic 회귀분석과 AHP기법을 적용한 결과에 동일 가중치를 부여한 후 7개 등급으로 재분류(reclass)하여 산사태 위험지역을 추출 할 수 있는 방법론을 제시하였다. 그 결과 산사태가 발생한 표본에서 1-2등급지역이 58.9%로 분석되어 분류정확도를 높일 수 있었다.

The aim of this retrospective study was to compare risk factors between men and women through secondary data of nursing information and medical records according to the severity classification in patients of 340 men and 221 women with coronary artery disease(CAD) who were admitted for the first time at a general hospital and underwent first coronary artery angiography. Consequently, men presented with risk factors such as age(p=.004), total cholesterol(p=.040), triglycerides(p=.049), HbA1c(p<.001), smoking(p<.001), alcohol consumption(p=.002) and comorbidities(p=.036) that showed statistically significant differences. Among women, age(p=.002) and comorbidities (p=.018) were the only factors that showed significant differences. Significant risk factors influencing the classification of CAD severity in men were total cholesterol (OR 0.97, 95% CI 0.96-1.00, p=.014) in 1VD, alcohol consumption (OR 52.47, 95% CI 2.99-91.95, p=.007)in 2VD, and total cholesterol in the 3VD(OR 0.98, 95% CI 0.95-0.98, p=.026). A significant risk factor affecting the classification of CAD severity in women was comorbidity (OR 0.30, 95% CI 0.11-0.82, p=.020) in the 3VD. This study identified the importance of nursing care for male CAD patients, such as smoking cessation and quitting drinking, blood sugar control, cholesterol, and accompanying disease management, and provided evidence of individually tailored nursing care.

Reagent Cabinet of existing that management does not classify the reagents by characteristics it has a problem that can result dangerous situations. Also, the situation impossible the ability to control the reagent cabinet from outside in the event of dangerous situations. In this paper, design a system for managing reagents it can be classified according to the characteristics and the reagent cabinet management on a mobile device. Utilizing the characteristics classification from first to sixth classification management to fit the classification of each reagent. The mobile device transmits the sensor control, reagent and sensor data monitoring, dangerous situation occurs when the alarm message. Accordingly, it is expected through the characteristics classification reduce accidents in the laboratory if the dangerous situation will be a prompt action from the outside.

위험물들은 위험물의 사용 및 관리뿐만 아니라 수송시에도 많은 위험성을 내포하고 있어 각국에서는 적당한 기준을 마련하여 특별히 관리하고 있다. 우리나라 철도 위험물안전수송에 관한 철도안전법 개정을 위하여 국내 철도 위험물의 수송량과 종류를 분석하고 국내외 위험물분류기준을 비교하였다. 우리나라는 지리적으로 대륙을 연결하기 편리한 위치에 있어 향후 국경을 넘어 대륙을 횡단하는 국제법을 채택하는 것이 유리하고, 수송되어야 할 물질의 종류가 다양해질 것을 대비하여 국제적으로 통용될 수 있는 위험물일람표를 채택하는 것을 제안하였다.

In this paper, we propose a classification method according to the type and characteristics of stablecoins for risk analysis, and analyze the risk factors of each stablecoin based on this classification. First, this paper explains the technologies and ecosystem of blockchain and decentralized finance(DeFi) to understand stablecoins. In addition, the operation principle of the major stablecoins currently released and used is explained for each proposed classification type. Based on this, the risk type and risk factors of each stablecoin are derived. The risk types proposed in this paper are classified as defegging, liquidation, and exploit, and the risk factors are classified as depegging due to reliability of operator, depegging due to reliability of algorithm, depegging due to failure of algorithm, liquidation due to high volatilty and oracle attack. Based on the proposed classification, we analyze the risk factors of major stablecoins currently circulating in the crypto market.
