스포츠이벤트의 운영 환경은 크기, 종류, 지역에 따라 다양하고, 단위업무별 업무가 독립적이지 않고 상호 유기적인 관계를 이루고 있으며, 복잡한 이해관계자가 매트릭스구조로 이루어져 있어 일반화된 운영 모델을 구축하는 것은 결코 쉬운 일은 아니다. 이 연구에서는 이러한 문제를 해결하기 위해 스포츠이벤트 관리의 개념 및 프로세스의 지침을 제공하는 '표준'을 제안한다. 표준개발을 위해 산업분야 및 활동의 품질경영을 위한 국제 표준 규격인 ISO 9001:2015에서 제시하는 프레임을 따라 표준화를 진행하였다. 이 연구에서 제안하는 표준의 구성은 적용범위, 인용표준, 용어와 정의, 조직의 상황, 리더십, 계획수립, 지원, 운용, 성과평가, 개선으로 구성되어 있다. 이 연구에서 제시하는 스포츠이벤트 프로세스 관리 시스템 표준은 스포츠이벤트의 형태 또는 규모에 관계없이 스포츠이벤트를 유치하고, 준비하여, 운영하고자 하는 모든 조직에 적용될 수 있다. 또한, 스포츠이벤트의 생애주기 단계별 프로세스 관리에 초점을 맞춘 접근방법을 시도하여, 프로세스와 프로세스 간 상호 관련성과 의존성을 관리 할 수 있도록 하였다.

The types of sixth industry to aim of boosting agriculture and rural areas and Korea's sixth industrial cases(Local community, production-centric, distribution-centric, dine out-centric, treatment-centric, export-centric) and competitiveness measures through Japan and China. Specifically, the competitiveness through the sixth industrial case is to maximize added value through cooperation between communities and to coexist among local residents. Efforts are needed not only to create jobs for the elderly but also to gain consumer confidence, and various measures should be sought to establish a cooperative system. In addition, as customers ' needs change rapidly in the smart age, the life cycle of goods and services is getting extremely faster. Therefore, the sixth industry is expected to be able to predict changes in customer and market trends quickly and accurately, thus making efforts to bring new products and services to market more necessary and contributing to achieving rural activation.

The lithium polymer battery with polymer electrolyte is expected as a safe and long cycle life battery. This paper reports primarily the recent development results of a solid polymer electrolyte, which is a key point of the secondary battery system. The new type of polymer electrolyte was prepared under a dry Ar atmosphere by dissolving $LiCIO_4$ in a matrix of EC, PC and then dispersing polyacrylonitrile(PAN). Also adding some inorganic filler $Al_2O_3$. The dispersed solution heated at $120^{\circ}C$. The polymer electrolyte were characterized by EIS(Electrochemical Impedance Spectroscopy), TGA(Thermo Gravimetric analysis), DMA(Dynamic Mechanical Analyzer), DSC (Differential Scanning Calorimetry). The lithium ion yield is 0.29 when PAN-$Al_2O_3$ which was applied DC 5mV. The ionic conductivity of PAN, PAN-$Al_2O_3$ polymer electrolytes were showed $1.0{\times}10^{-4}S/cm$, $8.4{\times}10^{-4}S/cm$ at room temperature. When inorganic filler was added in the polymer electrolyte, ionic conductivity and lithium yield more larger than without inorganic filler.

For mechanical system operating at high temperature, damage due to the interaction effect of creep and fatigue plays an important role. The objective of this paper is to develop a modified creep-fatigue damage model which separately analyzes the pure creep damage for hold time and the creep-fatigue interaction damage during startup and shutdown period. The creep damage was calculated by the general creep damage equation and the creep-fatigue interaction damage was calculated by the modified equation which is based on the frequency modified strain range method with strain rate term. In order to verify the proposed model, a service of high temperature low cycle fatigue tests were performed. The test specimens were made from inconel-718 superalloy and the test parameters were wave shape and hold time. A good agreement between the predicted lives based on the proposed model and experimentally obtained ones was observed.

During braking of railway vehicles the repetitive thermal shock leads to thermal cracks on disc surface, and the lifetime of brake disc is dependent on the number of trimming works for removing these thermal cracks. Many tries for development of high heat resistant brake disc to extend the disc life and to warrant reliable braking performance has been continued. In present study, we carry out the computational fatigue analysis for thermal fatigue test in three candidate materials which were made to develop new high heat resistant material. Using FEM, we simulate thermal fatigue test in three candidate materials and conventional disc material. We then estimate the number of cycle to thermal crack initiation based on data from mechanical fatigue tests, and the results are compared with each material. For each material, the correction factor for $N_{f-40}$ which is the number of cycles when crack over $40{\mu}m$ was observed in thermal fatigue test is decided. From this study, we can verify the performance of thermal fatigue test system and suggest a qualitatively comparative method for heat resistance by FEM analysis of thermal shocking phenomenon.

Purpose: This study identified the standardization activities from the early stage of acquisition to disposal during the materiel life cycle and proposed the improvement of standardization process. Methods: Through improvement of duplicated deliberation for the revision of military specification, unification of technical change proposal reception organization, and resolution between the conflicting parts of laws and regulations, simplifying the standardization procedure and strengthening linkages between the civilian standards were gained. Results: We have redefined the concept of the standards and standardization in the field of defense and proposed the standards-driven documentary standards as a measurement standards and reference standards to expand the activities. Conclusion: Through a standardization survey, we came to conclusion that we need to change the concept of standardization in the field of national defense from making the specification to using the means of efficient management of military resources.

Purpose: This study was conducted to develop an e-Learning program that assists nursing students' clinical Purpose: This study was conducted to develop and evaluate a web-based education program for secondary stroke prevention. Methods: A web-based secondary stroke prevention education program was developed using the system's life cycle methods and evaluated by comparing the effects of education among three groups, a web group, a booklet group and a control group. Results: Knowledge level of both patients and family, as well as some health behavior compliance in the web-based and booklet education groups were significantly higher than those of the control group. Family support in the web-based and booklet education groups was significantly higher than that of the control group after 12 weeks. The urine cotinine level in the web-based education group was significantly lower than that of the control group after 12 weeks. Medication adherence, blood pressure and perceived health status were not statistically different among the three groups at any time. Conclusion: Webbased and booklet education programs were equally effective regarding the level of knowledge of patients and their families, family support, health behavior compliance, and urine cotinine level. These results demonstrate the potential use of a webbased education program for secondary stroke prevention.
