This study examined relationships between parenting attitudes and young children's injury risk behavior by age and gender. Subjects were 161 3- to 5-year old children and their parents. Instruments were the revised Parenting Attitudes Questionnaire (Reitman et al., 2002) and the Injury Behavior Checklist (Speltz et al., 1990). Data were analyzed by MANOV A. Results were that: 1) Fathers were more permissive to daughters; mothers were more permissive to younger children. 2) Older children had more injury risk behaviors than younger children; boys engaged in more injury risk behaviors than girls. 3) Fathers' authoritarian and mothers' permissive attitudes were positively related to children's injury risk behavior, respectively. Fathers' and mothers' authoritative attitudes were negatively related to children's injury risk behavior.

가스의 수요가 늘어나면서 대량수요처에 대한 위험성과 안전성을 확보하기 위한 노력이 필요한 시점이다. 본 연구에서는 LPG저장탱크의 안전성과 경제성을 고려한 저장탱크를 파악하기 위하여 TRIZ 기법을 활용하였다. 지상형은 화염 등에 의한 위험성이 높으며, 지하매몰형은 부식 등에 의한 경제적 손실이 크다. 따라서 지상형과 매몰형에 대한 문제점을 해결하기 위해 6SC(6 Step Creativity)을 응용하였으며, 그 결과 지하격납형을 도출하였다.

QR 코드는 정부에서 지원하는 자전거 사업, wifi, 장비 및 공공기관 등의 관리 등 여러 분야에서 실생활과 밀접하게 쓰이고 있다. 하지만 QR 코드는 대체적으로 외부에 노출되어 있으며 이로 인한 훼손, 변조 등의 위험이 있다. 해당 연구에서는 위에 제시된 문제점을 개선하기 위해 플랫폼마다의 QR 코드의 규칙을 찾아내어 변조에 대한 위험을 줄이고 복구율을 높여 훼손에 대한 허용 범위 등의 개선을 기대한다.

Traditionally banks and other financial institutions use customers' accounts and information managed by them and provide payment services in dominant positions. Recently, EU amends Payment Services Directive to institutionally guarantee access to customers' accounts and use of account-related information even to third parties, which facilitates competition in financial markets and promotes innovation. However, this kind of change can increase potential security risks and therefore institutional responses from financial authorities are required so that all participants in financial markets can properly respond to security risks. In this study institutional responses to the security risks in the EU's new Payment Services Directive (PSD2) are analyzed, comparisons between this and domestic electronic financial regulations are analyzed, and implications for the direction of improving domestic electronic financial regulations will be suggested.

In reliability based design and assessment (RBDA) methodology, reliability targets are used to ensure that safety levels are met relevant limit states in the stage of design and maintenance. The target reliability for flammable gas pipelines have not been developed yet in Korea. Instead of the reliability targets, the tolerable criteria for risk measures such as societal and individual risk have been applied in pipeline risk management. This paper introduces the procedures to develop the target reliability using tolerable risk criteria for societal and individual risk which can be enforced for high pressure natural gas pipelines in quantitative risk assessment. In addition, we propose the target reliability for natural gas and hydrogen gas transmission pipelines by the procedures.

유럽연합의회는 1998년 12월 17일 사료첨가물에 관한 유럽의회규정(Council Directive 70/524/EEC, `70. 11. 23)을 개정(Council Regulation EC 2821/98)하여 그동안 사료첨가용으로 사용을 허용하였던 항생물질 중 아연바시트라신, 스피라마이신, 인산타일로신 및 버지니아마이신 등 4종의 사용을 금지하였다. 그러나 풀라보포스포리폴(풀라보마이신), 모넨신소디움, 살리노마이신소디움, 아빌라마이신 등 4종의 사료첨가용 항생물질은 계속 사용이 허용된다. 축산식품의 안전성이 강조되고 있는 가운데 유럽연합의 이러한 조치는 축산분야에 종사하는 사람들에게 커다란 관심을 갖게 하고있다. 이 글은 유럽연합이 4종의 항생물질을 사료첨가용으로 사용을 금지하게된 배경을 살펴봄으로서 유럽연합의 사료첨가용 항생제 사용금지에 관한 정확한 내용을 파악하는데 도움을 드리기 위하여 작성되었다. 유럽연합의 아연바시트라신, 스피라마이신, 인산타일로신 및 버지니아마이신 등 4종의 항생제에 대한 이러한 사용금지 조치는 가축의 성장촉진용으로 사용되는 이러한 항생물질에 내성을 획득한 가축의 세균이 인체에 기생하는 세균에게 그 내성을 전달하여 인체용으로 사용되는 관련 약품들에 대하여 내성을 일으켜 사람에서의 질병 치료를 어렵게 함으로서 인체의 건강을 해할 우려가 있다는 전제하에서 실시되었다. 이러한 조치는 현재까지 확실한 증거가 나타나지는 않았으나, 그 위험을 배제할 수 없으므로 이러한 위험을 예방하는 차원에서 이루어지는 예방적 조치이며, 따라서 금번의 사용금지 조치는 유럽연합 집행위원회에서 2000년 12월 31일 이전까지 이러한 항생제의 내성 유발에 관한 여러 가지 연구와 항생제 투여동물에서의 미생물 내성 감시 프로그램의 결과에 따라 재검토될 것을 규정하고 있다. 금번 사용금지 조치된 4종의 항생제는 그 동안 우리나라에서도 그 유효성과 안전성이 인정되어 축산 현장에서 사용되어온 물질들이다. 금번 유럽연합의 조치는 우리나라에서도 이러한 항생제들에 대한 재평가의 필요성을 제기하는 것으로서 이 분야에 종사하는 산업계, 학계, 연구계가 모두 힘을 모아 조속한 기간 내에 그 안전성을 재평가하여 축산식품에서의 안전성을 확보하도록 노력하여야할 것이다.

The Convention on the International Regulations for Preventing Collisions at Sea, 1972 (COLREGs) was adopted to prevent ships from colliding with other ships or any object such as the seabed. COLREGs have been codified and refined since the mid-19th century, and have reached the present. Therefore, the terms and sentences used in COLREGs also have distinct academic and legal connotations. However, in the Maritime Safety Act of the Republic of Korea, which translated COLREGs into domestic law, the "risk of collision" and the "danger of collision" was used in the law without distinguishing their meanings. Accordingly, the difference between "risk" and "danger" was analyzed with reference to the definition of risk by an authoritative international organization of the United Nations such as the International Maritime Organization and the International Organization for Standardization as a well-known and authoritative non governmental organization. In addition, the cases codified in COLREGs and translated cases in the Maritime Safety Act were analyzed to highlight the need for amending the Maritime Safety Act. From the perspective of safe navigation, it is expected that the Maritime Safety Act in the future would distinguish between "danger" and "risk" so that the efforts of watch officers to prevent collisions could be further systematized.

In order to study on the evacuation risk when connate fires caused by vertical fire spread of the exterior occurs, the egress simulations based on the relevant scenarios has carried out. As a result of it, ASET (permitted evacuation time) was reached in between 550 to 650 seconds in entire floors after vertical smoke spread from fire of combustible exteriors. In particular, ASET was 358 seconds in the first floor, 490 seconds in the six floor and 473 seconds in the tenth floor. In addition, five floors of all levels, the 1st floor, the 6th floor and the 28th floor ~30th floor, show RSET (minimum evacuation time) which is bigger than ASET as evacuation risk. This result presents occupants in high rise buildings with more than 15 floors might not be able to egress of them using staircases due to huge population attempting to evacuate simultaneously. Particularly, 699 people in the upper levels by smoke from the first floor are having difficulty escaping this building since ASET on the first floor adjacent to the ignition point was 358 seconds which is relatively reached fast. Considering a prevention method of the fire and smoke spread, architects have to use non-combustible exterior in the building's facade to be required as an active fire protection system.

Underwriting refers to the process that the insurance company measures the potential risk of the future clients and decide whether insuring them with current premium. Although the traditional underwriting system used in Korean automobile insurance market is easy to understand, it is not based on a reliable statistical procedure. In this paper, we propose to apply the generalized additive model into construction of underwriting system, which is based on statistical analysis. We use automobile insurance data in Korea and apply our approach to the data. The results from the empirical analysis would be useful even for determining the significance of each variable in calculating automobile insurance premium.

Probabilistic risk assessment was conducted on a hybrid cable-stayed bridge consisting of a steel-composite plate girder and a concrete girder with a long span, designed using the working stress design and strength design methods. The component reliabilities of the bridge's cables, pylons, girders, and steel-concrete conjunction were evaluated using the AFOSM(Advanced First Order Second Moment) algorithm and the simulation technique at the critical sections, based on the maximum axial force, shear, and positive and negative moments of the selected sections. For the analysis of system reliability, the hybrid cable-stayed bridge consisting of cables, pylons, and plate girders was modeled into combined failure modes, and for system reliability, the probabilities of failure and reliability index of the structural system were evaluated. Based on the results of this study, the critical failure modes of the hybrid cable-stayed bridge based on the bridge's structural characteristics are suggested, and the efficiency of the partial ETA technique for use in the risk assessment method was confirmed.
