To provide a development strategy on the method which assesses a potential risk of nationwide emerging IT infrastructure in planning and design phase, and to classify the assessment result into 5 levels is the goal of this research. The development strategy provided in this paper could improve a benefit-cost-ratio of investments on emerging IT infrastructure. With a premature assessment of the potential risks of a nationwide emerging IT infrastructure which needs astronomical amount of public funds, it could show a way of systematic investments on security systems and improve a benefit-cost-ratio of investments on emerging IT infrastructure. Also, this approach might improve the safety of nationwide IT infrastructure. It could identify and provide an optimized solution for the potential risks of nationwide IT infrastructure.

The purpose of business strategy is to achieve competitive advantages which includes higher efficiency, better quality, more innovation and faster customer response. In other words, The business strategy is to build unique capability of lower cost and/or differentiation. In production aspect, unique capability means better production power with better performance at 3M(Man, Machine, Material) of input and PQCDSM (Product, Quality, Cost, Delivery, Safety, Moral) from output. The Total Productive management (TPM), a series of improvement activities focused on reduction of equipment loss, is a tool to establish business competitive advantages. In this paper, several domestic companies who won the Japan TPM Award have been studied. It is found that there is a strong cause-effect relationship between TPM and competitive advantages because. 1. TPM can change employees mindset effectively. 2. TPM can upgrade employees capabilities. 3. TPM can lead to excellent productivity.

Korean government has endeavored to increase the exportation of agro-food, and the exporting processed food is one of the main concerns. However, there is little research to promote the exportation of Korean processed food, which is discussed in this paper. This paper analyzed the current situation of the exporting processed food and the government policy in Korea, and presents the strategy to increase the exporting. First, government programs should consider the market efficiency. Second, specified marketing strategies need to be developed after the overall analysis about the world market. Third, governmental support for product development and promotion should be expanded. Forth, efforts to increase the efficiency of logistics and food safety need to be magnified.

In order to control the output voltage in a dual active bridge converter, this paper establishes a theoretical inductor current equation for a dual-pulse-width-modulation scheme that ensures low switching loss. It also proposes a modulation strategy that minimizes conduction loss. When compared to the conventional single-pulse-width-modulation strategy, the proposed approach can reduce the inductor current RMS and improve efficiency in the low power region, as verified through simulation and experimental results.

Although the development of food technology is relatively fast, it's application is very broad. So, it is necessary that quantitative analysis method can be introduced in analysing of research trends and implication of research themes. Most countries do not classify in food additives as synthesis or natural. However, the use of natural food additives should be recommended by considering about health safety. In this regard, quantitative analysis based on bibliographic information of patents and papers is vital to analyse the trend of research on natural food additives. The data regarding with natural food additives was assigned patents and published papers in the world from 1996 to March 2016 and Thomson Innovation, analysis program was provided by Thomson reuters.

To cope with the change of railway safety environment and to prevent the catastrophic accident, the railway safety management system was established through the legislation of railway safety rules. And to audit and evaluate the accomplishment of railway safety rules by the railway operators, the Integrated Railway Safety Audit System(IRSAS) has been conducting. This study find out the strategy to stabilize the IRSAS by applying Theory of Constraints(TOC) Thinking Process. For meeting the IRSAS's goal of effective levelling up of railway safety, the two necessary conditions, 1)the secure of substantial safety through the IRSAS and 2)the execution of efficient IRSAS, should be fulfilled. Estimated undesirable effects(UDEs) from the IRSAS were identified, and 3 of them were selected for creating the requisite conflict clouds. Entities from these conflict clouds were synthesized into a core conflict cloud that foamed the base of Current Reality Tree. The strategic direction for change extracted from the conflict cloud is the reinforcement of IRSAS preparation system including the level up of operator's self audit, the deepening of preliminary survey, the establishment of complementing system of audit check list and the build up of auditor's specialization. These injection were logically validated via a Future Reality Tree and expected to be confirmed by further progressing of IRSAS.

Purpose: This study was undertaken to present an effective plan for the development of an educational program and a strategy to promote patient safety management activities for nursing students by identifying factors that affect these activities based on the theory of planned behavior. Methods: A self-report questionnaire was distributed to 300 nursing students who had clinical practice experience at three nursing colleges in Daejeon, Gyeongbuk, and Jeonbuk. The significance of the model fit, and the path effect was confirmed by confirmatory factor analysis. Results: The hypothetical model for patient safety management activities was appropriate. Among the 5 pathways, 4 were significant. It was found that behavioral intention had a direct influence on patient safety management activities, and perceived behavioral control and attitude had an influence on behavioral intention. Conclusion: To strengthen the perceived behavioral control of nursing students' patient safety management activities, it is necessary to analyze and remove obstacles and provide education that reflects the characteristics of the subject's health problems. In addition, through self-directed learning involving simulation practice, nursing students should be exposed to patient safety accidents, so that they can recognize the risks early and solve problems through critical thinking while bringing about the necessary changes in their attitude.

한국은 70년대 이후 자동차의 증가와 함께 교통사고로 인한 인명피해가 점차 늘어나 90년대 초 이미 심각한 공중보건문제로 등장하였다. 그러나 역대 정부는 사고예방과 사상자감소를 위한 대책 마련에 소극적이었으며, 다양한 관련전문분야의 협조로 달성 가능한 효과적 안전전략을 이끌어내지 못하였다. 이 논문은 한국의 사회경제적 발전과 교통안전 수준을 밝히고, 특히 전문 의료인의 참여를 요하는 교통안전전략을 조명하는데 목적을 두었다. 사회경제적 발전을 위해 6 가지, 교통안전을 위한 2 가지 지표를 조사하여 외국의 사례들과 비교했으며, 발전수준에 상응하지 못하는 낙후된 교통안전상태가 지속되고 있음을 보였다. 사회경제적발전과 교통안전의 이러한 불균형은 정부로 하여금 장차 관련전문분야 특히 의료인의 협력과 공조를 요하는 보다 효과적인 교통안전전략을 모색토록 할 것이며, 이에 대비하여 1984년 이후 국제교통의학회지 및 동 학회 학술대회에 발표된 논문과 경험들을 성찰하고 그들 중 중진국 수준으로 발전한 한국에서 실행가능하고 시도될 수 있는 주요전략 및 대책들을 분류 제시했다.

This Study is to analyze the characteristics of arson fire under fire dynamics to protect people and property from arson fire which has been radically increased with the development of the Korean economy. Assembly and merchandise purposes such as theater, retail, and exhibition has been performed as the arson fire study. The experiment for this study is based on the analysis of the characteristic for its own combustion process and smoke spread when arson fire occurs. This study presents the analysis through comparing the condition of setting fire using liquid fuel such as thinner on purpose to the condition of setting fire naturally depending on each occupancy.
