Coating is a type of paint. It protects a product forming a film layer on the product and assigns various properties to the product. Coating is one of the fields which is being studied actively in the polymer industry. Importance of coating in various industries is more increased. However, mixing process has been performing in dependence on operator's experience. In this paper, we found the relationship between each data from coating formulation process. We propose a framework to analyze the coating formulation process as well. It can improve the coating formulation process. In particular, the suggested framework may reduce degradation and loss costs due to absence of standard data which is accurate formulation criteria. Also it suggests responses to errors which can be occurred in the future through the analysis of the error data generated in mixing step.

Various personalized services are provided based on user context these days, and IoT(Internet of Things) devices provides effective ways to collect user context. For example, user's activity such as walking steps, calories, and sleeping hours can be collected using smart activity tracker. Smart scale can sense change of user's weight or body fat percentage. However, these services are independent to each other and not easy to make them collaborate. Many standard bodies are working on the documents for this issue, but due to diversity of IoT use case scenarios, it seems that multiple IoT technologies co-exist for the time being. This paper propose a framework to collaborate heterogeneous IoT services. The proposed framework provides methods to build application for heterogeneous IoT devices and user context management in more intuitive way using HTTP. To improve compatibility and usability, gathered user contexts are based on MPEG-UD. Implementation of framework and service with real-world devices are also presented.

Compared to the past infrastructure networks, the current smart grid network can improve productivity and management efficiency. However, as the Industrial Internet of Things (IIoT) and Internet-based standard communication protocol is used, external network contacts are created, which is accompanied by security vulnerabilities from various perspectives. Accordingly, it is necessary to develop an appropriate cybersecurity guideline that enables effective reactions to cybersecurity threats caused by the abuse of such defects. Unfortunately, it is not easy for each organization to develop an adequate cybersecurity guideline. Thus, the cybersecurity checklist proposed by a government organization is used. The checklist does not fully reflect the characteristics of each infrastructure network. In this study, we proposed a cybersecurity framework that reflects the characteristics of a microgrid network in the IIoT environment, and performed an analysis to validate the proposed framework.

This paper proposes security architecture, security audit framework, and audit check item. These are based on the security requirement that has been researched in the information system audit. The proposed information security architecture is built in a way that it could defend a cyber attack. According to its life cycle, it considers a security service and security control that is required by the information system. It is mapped in a way that it can control the security technology and security environment. As a result, an audit framework of the information system is presented based on the security requirement and security architecture. The standard checkpoints of security audit are of the highest level. It was applied to the system introduction for the next generation of D stock and D life insurance company. Also, it was applied to the human resources information system of K institution and was verified. Before applying to institutions, system developers and administrators were educated about their awareness about security so that they can follow guidelines of a developer security. As a result, the systemic security problems were decreased by more than eighty percent.

Purpose - The purpose of this study was to expound the packaging framework system(PFS) under international trade rules. Design/methodology/approach - This study analyzed packaging framework system and packaging regulations and technical standards in international regulations and major countries and classified these in some standards Findings - First, the study provides packaging provisions associated with packaging regulations and technical standards (PRTS). Then, the basis of PFS in international trade rules was proposed; it is believed that the PFS was composed of packaging legal system in WTO institutional framework (WTO-PLS), international organization packaging standard system (IO-PSS) and major countries or regions packaging regulatory system (MCR-PRS). Secondly, this paper expounded relations and legal characteristics of the three packaging systems. Finally, This study investigated PRTS coverage under technical barriers to trade (TBT) and Sanitary and Phytosanitary measures (SPS). Research implications or Originality - The regulations associated with PRTS have played a key role in challenges to merchandise trade in international trade. This study has significance in classifying packaging related reticulations into several criteria unlike previous studies. Therefore it is hope that this study can provide a supplementary document for the existing research of PRTS.

본 연구의 목적은 여러 학문에서 다루는 개념과 다양한 현상을 포괄하여 설명할 수 있는 원리가 되는 Big idea를 중심으로 교육과정에 기반을 둔 통합과학 교육과정(standard based integrated science curriculum) 틀을 설계하는 것이다. Big idea에 대한 학습을 통하여 학생들은 개별적인 사실 및 이론을 통합할 수 있을 뿐 아니라 영역 특정적인 지식들에 대한 총체적인 이해를 도모할 수 있다. 이를 위하여 2009 개정 과학과 교육과정에 제시된 초 중등학교 과학의 내용 영역을 분석하여 필수학습요소를 추출하였다. 필수학습요소들을 분석하고 범주화하는 과정을 거쳐 통합의 중심이 되는 네 개의 Big idea인 '다양성', '구조', '상호작용', '변화'를 선정하였다. 지식 피라미드를 이용하여 각각의 Big idea에 속하는 내용지식과 이들을 포괄할 수 있는 학문 내 개념, 간학문적 개념들을 위계적으로 나타내었다. 또한 Big idea를 중심으로 교육과정을 설계할 때 방향을 제시할 수 있는 본질적 질문들을 각각의 Big idea마다 제시하였다. 개발한 통합과학 교육과정 틀을 이용하여 교육 현장에 적용할 수 있는 방법을 구체화한 예시 모듈을 개발하였다.

Nurses use a nursing process. that is a scientific approach method. in order to understand the clients' condition and to solve their problems. Professional nurses have accepted the nursing process as a standard framework for nursing activities, and the first step of the nursing process is nursing assessment. The purpose of this study was to develop a nursing assessment tool for emergency patients. Assessment is a first step in the nursing process, and scientific assessment helps to better understand the patients. Thus the development of an assessment tool for emergency patients will improve of nursing quality and advance to efficacy of emergency room(ER) management. The study involved the development of a conceptual framework, preliminary tool, content validity verification process. and reliability verification process. The conceptual framework was developed through a review of the literature. and preliminary tool was developed from the conceptual framework that based on care flow sheet' developed James A. Haley. The preliminary tool was evaluated for validity and reliability by seven experts, one ER nurse manager, two ER head nurses, two emergency medicine doctors. and two ER charge nurses and by ten nurses with one to five year careers in ER nursing. The results of this study was as follows 1. The conceptual framework which was developed was composed of three parts. They were triage criteria, first assessment and secondary assessment. 2. The preliminary tool which was developed had 31 items based on the conceptual framework. 3. To test expert validity a 4-point scale was used. items which had gained 3-4 points from six persons of the seven experts were selected. All 31 items from the preliminary tool were selected. 4. The reliability test was done by ten nurses educated in the use of the assessment tool. Two pairs of nurses simultaneously assessed the same patients. A total agreement percentile was calculated and result was 87.3% agreement. 5. After the validity and reliability testing. the final emergency patient nursing assessment tool was finalized with 31 items. and a check-list for the responses. This study concludes that the tool which was developed is both valid and reliable will advance quality care for emergency patients. This emergency nursing assessment tool was also found to be an adequate tool for assessment of emergency patients.
