  • The AS9100 standard builds upon the ISO 9001:2000 quality management system requirements(in their entirety) and defines additional quality management system requirements for the aerospace industry. The 9100 standard on quality management system requirements is intended to be used at all levels of the supplier chain. The International Aerospace Quality Group has released a revision to 9100 for the aviation, space and defense industries. This change aims at improvement on quality, schedule and cost performance by adopting new requirements based on stakeholders' needs. This paper is to review how the AS9100 QMS Requirement has been established and improved, and to communicate the significant changes from AS9100, Rev. B to Rev. C focusing on reasons for revisions. The proposed schedule and considerations on the transition of the changes to Rev. C are also dealt with in this paper.

  • IS audit has been regarded as contributing to the improvement of the quality of information Systems, recently, it has been argued that it is not possible to expect a effectiveness, because it can offset the schedule burden due to the preparation of additional documents for Audit and it affect to the project schedule. The effectiveness and quality criteria of IS audit are different between groups, because IS audit is responsible for checking the results and process of the developer company. In this study, we modeled between IS effectiveness and auditor competence, audit firm competence, IS audit standards. As a result, it was concluded that auditor competence, audit firm competence, IS audit standards have a positive effect on IS audit effectiveness. However, according to the result of comparing between interest groups, audit firm competence and audit standards were significant in auditor group, but audit standard was significant in requesting organization and developing company thought that auditor was a important factor to audit effectiveness.

  • Objectives The purpose of this study is to examine the correlation of antibiotics administration duration and antimicrobial resistance by reviewing domestic and foreign literatures. Methods We searched literatures dated up to 23 February, 2018 in PubMed and Cochrane Library using terms of "Anti-Bacterial Agents", "Carrier State", "Nasopharynx", "Drug Administration Schedule", and also searched via RISS (Research Information Service System), KISS (Koreanstudies Information Service System), DBpia (DataBase Periodical Information Academic) using terms of antibiotics, resistance, and dose. Results In comparison with shortened and standard antibiotic course, longer treatment duration is associated with greater antimicrobial resistance or non-significant difference, but we cannot find literature that shortened antibiotic course increases antimicrobial resistance on human nasopharyngeal flora. Conclusions Currently, there is no evidence that completing the standard antibiotic course reduces antimicrobial resistance. It can be a strategy for reducing antibiotic use to apply Korean medicine treatment, as well as short-course antibiotic therapy or delayed antibiotic prescription. Additional well-designed trials should be conducted in domestic and foreign settings about the appropriate duration of antibiotic therapy.

  • This paper deals with a coal supply planning problem for power plants. We propose a mathematical optimization model to make decisions for coal pile sections, movement of reclaimers, and operation time of conveyor belts. The objective of the proposed model is to minimize the total operation time of conveyor belts and total movement time of reclaimers. The algorithm firstly selects a pile section by considering both the location of reclaimers and the stock amount on that pile section. And then the shortest path from the selected pile section has to be put into the operation schedule and check whether the total operation time is satisfied. Then finally the new schedule is updated. To this end, we have tested the proposed algorithm comparing with the general standard optimization package for the simplified problem SCSPP. From the numerous test runs for comparing with the existing coal supply scheduling methods, We see that the proposed model may improve the coal supply operation by reducing significant coal supply costs.

  • It is difficult to apply a design standard uniformly to university buildings because various education courses are conducted. However, a design guideline for saving energy is necessary in order to prepare for low-energy days. A library in any university is one of the buildings that a lot of people use and most of the energy is spent. Therefore, the investigation on the energy savings of library facilities is very important and urgent. This study finally presents the design guideline of those facilities for low-energy. In this paper, the trend of space layout, utilization schedule and performance of materials are investigated, and the impact on energy savings and effective energy saving strategies are analyzed and illustrated by energy simulation. As a result of energy analysis from the case of 'H' university, it is confirmed that the utilization schedule effects mostly to energy consumption and the layout and orientation of the rooms in the library are the major parameters. Among the investigated saving strategies, green roofs are found as the most effective part for heating energy savings, and outdoor air cooling is known as the most effective method for cooling energy savings.

  • Objectives: We examined the agreement between the Autism Diagnostic Observation Schedule (ADOS) and the Childhood Autism Rating Scale (CARS) in the diagnosis of autism spectrum disorder. Methods: The ADOS and CARS scores of 78 children were retrospectively collected from a chart review. A correlation analysis was performed to examine the concurrent validity between the two measures. Using the receiver operating characteristic (ROC) curve, we determined the optimal cut-off score of the CARS for identifying autism spectrum disorder. Results: The CARS score was significantly correlated with the ADOS score (r=0.808, p<0.001). Taking ADOS as the ideal standard, the optimal cut-off scores of CARS for identifying autism and autism spectrum were 30 and 24.5, respectively. Conclusion: We determined the optimal cut-off scores of CARS for screening and diagnosing autism spectrum disorder.

  • 국외 IT 선진국들은 1980년대 후반부터 정보시스템의 안전성과 신뢰성을 확보하기 위하여 정보보호제품 평가기준을 개발하여 활용하고 있다. 현재 다양한 제품의 평가를 위한 기준으로 CC를 사용하고 있으며 오랜 기간이 소요되는 제품 평가기간의 단축이 개발자 및 사용자에게 요구된다. 본 논문에서는 공개된 표준 평가기간을 참고하여 EAL4 등급의 평가기간 산정 모델을 제안한다. 또한, 이를 바탕으로 투입하는 평가자의 수와 평가 일정을 조정하여 평가신청인 입장에서 평가기간이 최소화 되는 방법을 제안한다.
