Chemical accidents occur by a variety of causes and aspects. Accident preparedness substances (APS) are defined by toxic chemicals highly likely to cause accidents due to their high acute toxicity, explosiveness or likely to cause severe damage where a chemical accident occurs among the chemicals. APS is designated and announced by Presidential Decree. However, chemical accidents occurred for recent 7 years were arisen mainly from non-accident preparedness substances, and only 24 species were included as chemical accident trigger among total 69 APS. In addition, APS were designated in 2014 and the list has not been updated since then although it needs to be amended in several aspects. Accordingly, this study analyzes the necessity of modification of APS management, and presents improved plans.

In this quantitative research, it was enhanced to understand the impact of intrinsic motivation on creative process engagement by examining the significant role of psychological safety on intrinsic motivation. These relationships were examined by targeting the employees working full-time for five star deluxe hotels. Total number of 230 responses had been collected out of 250 cases requested and he number of 213 cases was used for the final analysis. The data were analyzed using structural equation modeling with SPSS 19.0 and AMOS 7 software program. The results suggested that psychological safety is significantly associated with intrinsic motivation. Furthermore, the hotel employees' problem identification, information searching & coding, and idea generation are affected by intrinsic motivation. That is, intrinsic motivation plays a significant role for each sub-factors of creative process engagement in the hotel industry. The theoretical and practical implications of these findings are established and related suggestion for formulating marketing strategy is well discussed.

Reliability Centered Maintenance (RCM) introduces a systematic method and decision logic tree for utilizing previous operating experience focused on reliability and optimization of maintenance activities. In this paper RCM methodology is applied on safety injection system for APR-1400. Functional Failure Mode Effects and Criticality Analysis (FME&CA) are applied to evaluate the failure modes and the effect on the component, system and plant. Logic Tree Analysis (LTA) is used to determine the optimum maintenance tasks. The results show that increasing the condition based maintenance will reduce component failure and improve reliability and availability of the system. Also the extension of the surveillance test interval of Safety Injection Pumps (SIPs) would lead to an improved pump's availability, eliminate the unnecessary maintenance tasks and this will optimize maintenance activities.

In modern diet relying heavily on processed food, it is difficult to live without food additives, added to food regardless of whether consumers want or not. This poses the following questions: Are food additives really safe? Are they toxic? Are they cancerous? Are they still good to eat? Are there any concerns on excessive intake and interactions? Is toxicity testing adequate? Is ADI evaluation being set up properly? In this article, I discuss a desirable management strategy for food additives, by addressing these questions and concerns and analyzing and reviewing current status of food additive management.

While commercialization of IoT technologies in the safety management sector is being promoted in terms of industrial safety of large indoor businesses, implementing a system for risk management of small outdoor work sites with frequent site movements is not actively implemented. In this paper, we propose an efficient dynamic workload balancing strategy which combined low-power, wide-bandwidth (LPWA) communication and low-power Bluetooth (BLE) communication technologies to support customized risk management alarm systems for each individual (driver/operator/manager). This study was designed to enable long-term low-power collection and transmission of traffic information in outdoor environment, as well as to implement an integrated real-time safety management system that notifies a whole field worker who does not carry a separate smart device in advance. Performance assessments of the system, including risk alerts to drivers and workers via Bluetooth communication, the speed at which critical text messages are received, and the operation of warning/lighting lamps are all well suited to field application.

Safety of workers and productivity in construction site are affected according to the conflict status of work spaces which are performed at a time. The interference among the work spaces in construction site should be minimized because it becomes a blocking factor that causes construction delay and low productivity. Those factors can be managed by reasonable H&S (Health & Safety) practice. This research suggests the requirements of H&S practice and rules to establish the strategy of H&S management based on the literature reviews related to H&S rule. The suggested H&S rule can be visualized for searching space conflict point if the rule is linked with visual simulation tool. Accordingly the research results can be used for improving and visualizing construction productivity by work space control in 4D/nD CAD system.

South Korean national security strategy should be developed to effectively handle and counter increasing maritime threats and challenges. There are three major maritime threats South Korea faces today; maritime disputes on the EEZ boundary and Dokdo islet issues, North Korean threats, and international maritime security. Maritime disputes in the region are getting intensified and turned into a military confrontation after 2010. Now regional countries confront each other with military and police forces and use economic leverage to coerce the others. They are very eager to create advantageous de facto situations to legitimize their territorial claims. North Korean threat is also increasing in the sea as we witnessed in the Cheonan incident and Yeonpyoung shelling in 2010. North Korea resorts to local provocations and nuclear threats to coerce South Korea in which it may enjoy asymmetric advantages. The NLL area of the west sea would be a main hot spot that North Korea may continue to make a local provocation. Also, South Korean national economy is heavily dependent upon foreign trade and national strategic resources such as oil are all imported. Without an assurance on the safety of sea routes, these economic activities cannot be maintained and expanded. This paper argues that South Korea should make national maritime strategy and enhance the strength of naval forces. As a middle power, its national security strategy needs to consider all the threats and challenges not only from North Korea but also to maritime security. This is not a matter of choice but a mandate for national survival and prosperity. This paper discusses the importance of maritime security, changing characteristics of maritime threats and challenges, regional maritime disputes and its threat to South Korea's security, and South Korea's future security strategy and ways to enhance the role of naval forces. Our national maritime strategy needs to show middle and long term policy directions on how we will protect our maritime interests. Especially, it is important to build proper naval might to carry out all the roles and missions required to the military.

현재 우리나라 신호교차로는 긴급차량에 대한 우선신호(Preemption) 제어전략을 적용하지 않고, 긴급차량의 교차로 진입 및 통과여부와 관계없이 일반적인 신호로 운영되고 있다. 본 연구에서는 국내외 긴급차량 Preemption 제어 전략을 검토하고. 이를 국내 교통상황을 대상으로 시뮬레이션을 통해 평가하여 교통상황에 따른 효과의 변동성을 분석하였다. 그리고 실제 현장자료를 기반으로 평가하여 국내 적용성 평가를 실시하였다. 분석결과 긴급차량 preemption 제어가 긴급차량의 운영에 긍정적인 영향을 주나 v/c가 증가 할 수록 이와 같은 효과는 감소하는 것으로 나타났다. 그리고 일반차량의 경우는 preemption 제어로 인하여 지체가 증가하고 통행속도가 감소하였으나 네트워크 전체적으로는 큰 차이가 없는 것으로 분석되었다. 그러므로 교통상황에 따라 개선효과의 차이는 존재하지만, preemption 제어 알고리즘을 국내에 도입한다면 사회적으로 긍정적인 효과가 있을 것으로 기대된다.

OECD는 규제개혁을 '보다 나은 규제'와 '규제폐지'로 구분하고, 환경 및 안전 분야의 규제는 지속되어야 한다고 강조한다. 반면에, 1990년대에 진행된 한국소방의 규제개혁은 일방적인 규제의 완화 또는 폐지라는 방향으로 진행되는 매우 기이한 현상을 나타내고 있다. 영국 소방예방법규의 경우, 1971년 화재예방법의 제정 이후 대형화재의 발생에 대응하여 지속적으로 예방법규를 강화해 오고 있으며, 1991년 건축령에서는 주택을 포함하여 모든 건물에 대하여 각층에 최소 한 개의 연기경보기를 설치할 것을 의무화하고 있다. 이 연구는 영국에서의 소방예방법규의 강화가 소방안전을 제고 시켰다는 것을 보여 주고 있는데, 이것은 한국소방에 시사하는 바가 크다. 한국소방의 경우 화제로부터 시민의 생명과 재산을 보호하기 위해서 '안전, 보건, 환경과 관련된 규제의 질을 개선한다'는 규제개혁위원회의 규제개혁 기본방향이 철저히 준수되어야 하며, 비록 규제개혁의 전체적 전략이 모든 규제를 감소시키는 것일지라도 안전에 관한 규정은 오히려 증가시킬 수 있다는 기본방향의 유연성이 확보되어야 한다.
