Concept about health is rapidly changed into 21C. thinking logic of customer about food is changed from just food to safety food by disposition of consumption about foodsafety. But government, manufacturer, distribution trader and seller which have different recognitions about foodsafety lose trust of customer. Because they did't focus on thinking changed of customer about foodsafety. Our thinking about rapidly changed food safety being intergrated with IT technology is helping to expand and supply into market. In this article, We'll study Traceability System about cattle and pig related to food. this system was developed in livestock market. In this study, we problems from these systems after studying present construction positions of these systems and purpose of this study is investigation of actual use condition. Also purpose of this study abstracts problems which will be developed and researched.

ISO 9001 Quality Management Systems-Requirements has been revised in 2015. It has been updated four times since its publication in 1987. It is the most widely used International Standard in the world. There are over one million companies and organizations in over 170 countries certified to ISO 9001 from an ISO survey. Organizations are supposed to be certified to this new version by late 2018. The key changes in ISO 9001:2015 are to establish a High Level Structure (HLS) and focus on Risk-Based Thinking (RBT). Risk-Based Thinking means the process approach to decide how risk is addressed in establishing the processes to improve process outputs and prevent undesirable results. It pursues process planning and controls based on risks so that organizations can improve the effectiveness of the quality management system. It maintains and manages a Quality Management System that inherently addresses risks and meets objectives. In this article we firstly attempt to explain how to understand the fundamental concept of Risk-Based Thinking which is a systematic approach to consider risks rather than treating prevention as a separate component of a Quality Management System. We comment on the detailed requirements that contain risks in ISO 9001:2015 clauses. We also summarize recent advances on the risk assessment and management in line with ISO 31000:2009 Risk Management-Principles and Guidelines. We finally propose the practical risk management procedures for implementing ISO 9001:2015 with an emphasis on RBT. This article would contribute to help quality managers and practitioners convert to ISO 9001:2015.

Purpose: This study investigated the effects of reeducation of nursing process on nurses' expertise, critical thinking disposition, and clinical decision making. Methods: Data were collected from March to June, 2007. The subjects were 47 Academic Credit Bank System Student Nurses. They were taught 'nursing process' during 1 semester(15weeks). 47 nurses were divided into three groups according to clinical experience(under 3 years, 3 to under 5 years, 5 years or more). After 15 weeks, the effects of education were compared using a paired t-test between pre-test and post-test. Results: There was a significant difference in the 3 to under 5 years experienced nurses's expertise(t=-3.659, p=.004) between the pre-test and post-test. There was a significant difference in the 5 years or more experienced nurses's expertise(t=-5.781, p<.001) and critical thinking disposition(t=-3.345, p=.003) between the pre-test and post-test. There were no significant differences in clinical decision making(accuracy, proficiency, and confidence) of 3 groups. Conclusion: Reeducation of nursing process is a valuable teaching and an evaluation strategy for 5 years or more experienced nurses to improve expertise and critical thinking disposition. We need to develop continuing education program for improving nurses' clinical decision making.

This study structurally analyzes major inefficiency of Korea's healthcare delivery system by utilizing the systems thinking. In particular, the phenomenon of patient's concentrated visits to large hospitals, waste of resource due to competitions between clinics and large hopitals, and the structure of oversupply were visualized using the causal loop diagram. The inefficient structure of healthcare delivery system can be understood more clearly by utilizing the major system archetypes of 'success to the successful', 'tragedy of commons', 'escalation' and 'limits to growth'. This study also finds solution from archetypal structure suggested by Wolstenholme. The inefficient status of healthcare delivery system might be explained by the 'out of control' archetype. In conclusion, the public resources such as the national health insurance need to be acknowledged as the entire achievement. All the participants should cooperate with each other in order to improve the inefficiency of the healthcare delivery system. In addition, the arrangement of incentive system for cooperation, acceleration of health information technology, and development of innovative business models make the sustainable healthcare delivery system.

This Study discuss exploring normative-prescriptive factors after the themes on Organizational learning categorize two descriptive/explanatory-perspectives, prescriptive/normative dimension. The former would contain information processing model, theory of action, organizing in organization, while Senge's suggestion on Learning Organization may compose the latter. Each perspective is reconstructed and reinterpreted into the causal mapping relationship founded on system thinking and SD. Underlying on the former try to discovery validities of the latter. But this study only put forward the integral-dynamic model of organizational learning without empirical simulation.

Recently, in the fields of fashion, advertisement, film, literature, philosophy, etc., the word, 'Nomad', is being used frequently across the overall society. The contemporary society is actively incorporating "nomadic thinking" as a new social phenomenon across the boundaries of conventional fields. This is not an exception in the field of space design. This study, via the contemporary nomadic thinking, examined the relationship between space design's application possibility as a new trend and flexible space; then categorized the characteristics of flexible space into flexibility, temporariness, changeability, and correlation; and then analyzed expression characteristics of flexible space. As for unrestricted expression of scene, it was recognized that separation of scene and space leads space to meet the needs of surrounding environment and users; formation of changeable space enables uses of space from various perspectives; and combining external factors (energy, media technologies) with space leads space to self-evolution. Space is perceived as an living organism that is flexibly corresponding, via realistic movement and virtual movement, to the indefinite, diversified thinking of the contemporary society. Therefore, this study illuminates that nomadic thinking has significance as basic thinking to predict development and characteristics of design thinking through understanding the contemporary society with the basic thinking system that has been inherent without restrictions of being fixed to the present, past, and future.

The purpose of this study is to explore the applying possibility of the Earth Systems Education(ESE) in elementary school science education through the improving of students' recognition with the earth systematic nature by systems thinking education - for this was the recognizing as earth systematic nature was the key element of ESE, and the systems thinking skill is accredited very effective tool for the understanding with earth systematic nature. For this, the systems thinking's teaching-learning programs were developed and applied to the 6th students (21s) for 10hours' classes. The results of this study are as follows; In most of the 6th students didn't recognize with earth systematic nature from a lack of understanding of the vapor being in every nature environments. In systems teaching-learning classes, most of students participated positively in learning activities and achieved the aim of a lesson. In the testing results for students' recognition improving to earth systematic nature after the systems thinking education, about 24% students were showed the improving results of the recognition with earth systematic nature. Consequently, It is suggested that just as the achieving of the points of ESE in elementary school science education, the approaching method of the systems thinking education is worth attempting to applying of the ESE.

The purpose of this study is to analyze the factors giving effects to juvenile's suicide thinking and search for the method to protect juveniles from the risk factors of suicide thinking and reinforce protective factors. For this purpose, juvenile's depression and stress degree were analyzed as the factors giving effects to juvenile's suicide thinking and the effect of social support, which was assumed as a protective factor from suicide thinking, was verified. Analysis results are as follows. First, juvenile's daily stress showed significant deference from suicide thinking. There was a significant positive correlation between juvenile's daily life stress and suicide thinking. Therefore, it was found that the juveniles who suffer from stress have a lot of suicide thinking. Second, juvenile's depression gave a significant effect to suicide thinking. There was a significant positive correlation between juvenile's depression and suicide thinking. it was proved that the juveniles who suffer from depression have a lot of suicide thinking. Third, There was a significant negative correlation between social support and suicide thinking. The more the juveniles get social support, the less they have suicide thinking. The study results above reveal that juvenile's suicide shall be approached from the preventive aspect, for preventing juvenile's suicide, social support which mitigates suicide thinking factors is very important. Therefore this study proposed social attention on the juvenile's suicide thinking, and formation social support system that reinforce social support. Moreover, for preventing the factors reinforcing suicide thinking, preventive approach, alternative program such as case management and group program, and integrated management inined with juvenile related organizations and specialists are required. At the same time school environment shall be improved and changed.

Recently in major industrial areas, there has been a rapidly increasing demand for 'Computational Thinking', which is integrated with a computer's ability to think as a human world. Developed countries in the last 20 years naturally have been improving students' computational thinking as a way to solve math problems with CAS in the areas of mathematical reasoning, problem solving and communication. Also, textbooks reflected in the 2009 curriculum contain the applications of various CAS tools and focus on the improvement of 'Computational Thinking'. In this paper, we analyze the cases of mathematics education based on 'Computational Thinking' and discuss the mathematical content that uses the CAS tools including Sage for improving 'Computational Thinking'. Also, we show examples of programs based on 'Computational Thinking' for teaching Calculus in university.
