This study presents an information security level index and a quantification scheme. A comprehensive survey on previous researches in information security checklists has been performed. A candidate indicator list for information security level has been developed, Desirability of each indicator has been tested by 4 criteria, They are general validity, relative importance, probability of accident and impact of accident. 67 experts' opinion has been collected and analysed. The result shows that selected indicators are a very good candidate set for the determination of information security level. A factor analysis shows indicators are well structured. There exists strong correlation between validity and probability, validity and impact, and importance and probability. A quantification scheme of information security index has been developed by experts' judgement and statistical tests.

This study aims to find the main factors to influence consumers' purchase of dairy products. To do so, we examined experts' opinions to verify the priorities of the factors. The four main factors were derived from the previous studies, product factor, marketing factor, quality factor, and social factor. Using analytic hierarchy process (AHP), we empirically analyzed and tested the results from survey. Based on the AHP analysis, the expert group recommended to improve the packaging, brand, and shelf lie of dairy products for the marketing factor, for instance. The results of this study can contribute to the development of the dairy products for the future to reveal the importance of the selecting factors.

Construction Standard Specifications, part of contract documents, has been improved through various amendments since their first enactment in 1967 up to the latest 2013 version. However, complaints about inconvenience and low availability have been continuously made in their structure and contents. Therefore, an improvement is needed based on the experts' opinions both from industrial and academic fields. This basic study is to compare the Korean specifications to those from the developed countries and derive the suggestions on their improvement. Furthermore, it aims to delve into the experts' opinion on the subject and identify the direction and priority for the improvement of the specifications. Through this study, user friendliness and efficiency are expected to be obtained in using the specifications.

The purpose of this study is to analyze the setting and directions of cross-curricular learning topics based on research on experts' recognition of cross-curricular learning topics. The study method adopted was Delphi, and the subjects selected were curricular experts. This study has drawn following results: first, regarding the essence and problems of cross-curricular learning topics, even among the experts, there is no opinion agreed about cross-curricular learning topics' concept, essence, or characters. Second, more detailed discussion is demanded to select cross-curricular learning topics and set up a guideline about the operation. Third, it is needed to examine closely if presently suggested cross-curricular learning topics are duplicated or not and consider related subjects connected with those cross-curricular learning topics to improve education more systematically. Fourth, it is necessary to conduct more profound and systematic research on core competence that can embrace those cross-curricular learning topics. Fifth, to cope with changes in society and demands at school, it is needed to discuss how cross-curricular learning topics should be added or which learning topics should be added.

Methods The CPG was developed by the national-wide experts committee considering of the society of Sasang Constitutional Medicine. It was performed by search and collection of literature related SCM, opinion of SCM experts and journal search and it was followed by CPG's guideline. Results & Conclusions The CPG of Yin-Depletion (Mangeum) Symptomatology in Soyangin Disease include classification, definition and standard symptoms of each pattern. Yin-Depletion (Mangeum) Symptomatology is classified into severe and critical pattern by severity. The severe pattern of Yin-Depletion (Mangeum) Symptomatology is classified into the pattern of Heat-related diarrhea accompanied by headache (Sinyeol-dutong Mangeum) and the advanced pattern of Heat-related diarrhea accompanied by headache (Sinyeol-dutong Mangeum). The critical pattern of Yin-Depletion (Mangeum) Symptomatology is classified into the pattern of Cold-related diarrhea accompanied by the abdominal pain (Sinhan-bocktong Mangeum) and the advanced pattern of Cold-related diarrhea accompanied by abdominal pain (Sinhan-bocktong Mangeum).

FMECA는 전력설비의 기능, 고장 모드, 고장 원인 및 고장의 파급 효과 등을 분석하고 각 고장 모드가 시스템의 기능 유지에 영향을 미치는 정도인 심각도(Severity)와 고장 발생의 빈도의 정도인 치명도(Criticality)를 평가하여 치명도 매트릭스(Criticality Matrix)를 구성함으로써 높은 위험성을 갖는 고장 모드를 판별하고 효과적인 시스템 구성을 위한 참고 자료를 제공한다[4-5]. 대부분의 경우, 고장 모드의 두 지수는 미리 정해진 기준에 따라 전문가들의 정성적인 평가에 의해 결정된다. 따라서 본 논문에서는 두 지수들에 대한 다양한 전문가의 의견을 종합하여 결론을 도출하기 위한 방법론으로 기존의 Linear Opinion Pool에 퍼지이론을 결합하는 방식을 제안하였다. 또한 기존의 치명도 매트릭스 방식으로 위험도를 판별하던 방식의 한계를 인식하고 운영자의 관심에 따라 두 지수를 종합적으로 평가하기 위해 퍼지 FMECA 전문가 시스템을 구성하였다.[7-8]. 사례연구에서는 대표적인 전력 설비에 대한 적용 예를 나타내었다.

As respiratory tract infections (RTI) account for about 60% of all antibiotic prescriptions in outpatient care setting, there are significant concerns about emerging resistance that are largely due to the excessive or inappropriate use of antibacterial agents for viral respiratory infections. This study was aimed to develop retrospective drug utilization review (DUR) program of antibiotics for RTIs using Delphi methods. Retrospective DUR criteria of antibiotics for RTIs were identified based on clinical practice guidelines and opinion of experts. Expert panel members were clinical doctors and pharmacists and Delphi method was applied by survey on 16 members of panels. The claim data from Korean Health Insurance Review & Assessment (HIRA) were used to examine trends in outpatient antibiotic prescription between Janunary to December of 2008. As results, Quality index for RTI was assessed for the claim type, antibiotics use of quantity, duration, number and cost. Antibiotic prescription rate for RTIs, Defined Daily Dose (DDD), and duration of antibiotics use were more recognized as significant quality index by experts' opinion. Use of first line agents suggested by guidelines was low and duration of antibiotics use was shorter compared to the recommendations. Antibiotics were over prescribed for RITs. However, dose and duration of antibiotics were under-used.

Recently, low hydrogen carbon production technology is drawing interest due to lower production costs. Although the pace of research in this field has been accelerating, there is no well-established criteria for evaluation. The most of current evaluation methods needs information related to technology. However the technology is not enough to provide effective evaluation criteria because the technology is not fully developed. In this study, we propose an integrated Delphi-analytic hierarchy process (AHP) method and low carbon hydrogen production technology evaluation model. Experts opinion is used to provide evaluation criteria for the technology. In this study, integrated Delphi-AHP method are utilized for determining factors and calculating their numerical importance based on experts opinion. Then, sensitivity analysis is performed to verify the robustness of the analysis and scenarios of potential changes. As many as 11 factors are identified by Delphi method. Then, numerical importance of the factors are calculated by AHP. Sensitivity analysis is performed. It shows that intellectual property right (IPR) is always more important than other factors. This study proposes the numerical standard for the low carbon hydrogen production technology evaluation. The proposed model can be used for technology evaluation or commercialization.
