Catastrophic events cause casualties, damage property, and lead to huge social impacts. To build common standards and facilitate international communications regarding disasters, the relevant authorities in social management rank them in subjectively imposed terms such as direct economic losses and loss of life. Terrorist attacks involving uncertain human factors, which are roughly graded based on the rule of property damage, are even more difficult to interpret and assess. In this paper, we collected 114 183 open-source records of terrorist attacks and used a machine learning method to grade them synthetically in an automatic and objective way. No subjective claims or personal preferences were involved in the grading, and each derived common factor contains the comprehensive and rich information of many variables. Our work presents a new automatic ranking approach and is suitable for a broad range of gradation problems. Furthermore, we can use this model to grade all such attacks globally and visualize them to provide new insights.

This paper presents a theoretical research framework that was used to analyse operational risk management (ORM) system practices in Australia. It provides a new perspective on how to use national and international operational management system standards as a basis for systematic management of operational risks. Based on the extensive literature review and the analysis of operational risk management system practices that are common in Australian organisations, this paper identifies the critical factors for effective use of an ORM system. The proposed framework could also be used as a model to research ORM system applications in other countries.

The Enterprise Security Management system is a centralized control system based on predefined security policies by organizations. In Korea, there is a Common Criteria security certification according to the strict standards for various features. As the needs of information security product are increasing, the ESM system should be evaluated with quality characteristics. In this paper, we propose evaluation items for functionality and performance of Enterprise Security Management system, and the best practices for evaluation.

Distribution systems for operating the various systems should be operated organically. Distribution systems for organic operations extend the functionality of the system and system integration for the extension is doing. However, in systems integration for each unique non-standard definition of linkage and exchange systems are used. Non-standard definition of a unique linkage and exchange systems in the maintenance and expansion will result in many negative results. To solve these problems, the system and the exchange of information about the links between systems should define standards. IEC (International Electrotechnical Commission) power to solve these problems in the field of the Common Information Model (Common Information Model, CIM) standard (IEC61970, IEC61968) is defined as the transmission and distribution system integration and standardization for the exchange of information. In this paper, standardized system for building CIM-based distribution automation system should describe the process of building. In addition, the process of establishing a common information model needed (CIM) defined and associated services for a defined set of models is proposed in the standardization process.

조직의 가치는 구성원의 신뢰를 형성하고 참여를 활성화한다. 따라서 전통적인 도서관 가치인 접근성과 지원 이외에 학교도서관의 새로운 핵심 가치를 찾는 활동이 필요하다. 본 연구에서는 국제적인 학교도서관 기준의 사명과 비전의 중심 단어를 분석하고 교육, 협동, 접근성, 문화적 소양, 민주시민 등 5개 영역의 핵심 가치를 도출하였다. 그리고 미국, 호주, 영국, 캐나다 학교도서관 기준의 사명과 비전을 분석한 결과 공통적으로 평생학습능력과 물리적 접근성 그리고 사회적 책임감을 강조하고 있는 것으로 나타났다. 특히 최근에 학교도서관 기준을 개정한 영국과 미국은 정보공학기술과 다중 정보활용능력 그리고 통합 정보활용교육과정 운영을 강조하고 있다. 궁극적으로 이러한 핵심 가치는 국내 학교도서관의 사명과 비전을 수립할 때 방향 설정과 기초 자료로 활용할 수 있을 것으로 보인다.

본 연구는 시력보정용 안경렌즈와 관련된 KS규격과 ISO, JIS 및 ANSI 규격을 비교하고 시중에 유통되고 있는 안경렌즈를 각 규격에 합당한지 여부를 판단하여 현 KS규격의 문제점과 개선책을 검토하였다. KS규격은 ISO규격을 대응으로 하고 있고 단초점과 다초점 및 누진을 통합한 규격인 ANSI 규격의 구조를 가지나 용어의 정의와 누진렌즈에 관한 내용이 없다. 검사항목은 ISO규격에 준하고 있지만 ANSI 규격과 비교시 광학적 요건이나 기하학적 요건이 없는 사항도 있었다. 유통되고 있는 안경렌즈의 주요 항목 평가에서 굴절력, 렌즈의 치수, 외관 및 품질 등에 관한 것은 명시된 것과 큰 차이점은 없었으나 렌즈의 두께나 베이스 커브 및 가시광선 또는 자외선의 투과율에 관한 기준이 없고 제품 간의 차이가 있어 이에 대한 기준이 필요하다.

21세기 지식 정보 사회의 창의적인 인재 양성을 위해 2018년도부터 초등학교에서 소프트웨어 교육을 실시한다. 2015년에는 초등학교에서 실시되는 소프트웨어 교육의 교육 내용과 성취기준을 만들었다. 본 연구는 초등학교 교사 199명을 대상으로 소프트웨어 교육에 대한 인식을 조사했고, 조사 결과는 다음과 같다. 첫째, 소프트웨어 교육이 초등학교에 필요하고, 17시간으로는 부족하다. 둘째, 현재 교사들은 일반적인 소프트웨어 교육의 교육 내용, 교수 학습 방법, 평가 방법, 자료 개발 방법 등의 내용을 잘 모른다. 셋째, 성취기준에 대한 이해, 성취기준 적합한 교육 자료 개발과 지도 방법에 대해서도 인지가 낮다. 따라서 초등학교 모든 교사가 교사 연수를 통하여 성취기준에 적합한 교수학습 자료 개발, 평가 방법, 지도 방법을 알 수 있게 해야 한다.

We intended to measure the IT, MT, and the IMT of carotid artery separately and tried to analyze the clinical significance. Two hundred and fifty consecutive patients (125 males, 125 females) underwent carotid artery scanning using high-resolution ultrasound. The images were off-line analyzed using B-mode ultrasound image processing, devised in our research. We measured the IT, MT, and IMT semi-automatically at the far wall of designated 1cm length of the right common carotid and calculated the average values over the 200 points. The IT (p < 0.05), MT (p < 0.05) as well as IMT (p < 0.01) of patients with atherosclerotic disease were significantly thicker than that of the patients without atherosclerotic disease. Patients with hypertension showed significantly thicker IT (p < 0.05), MT (p < 0.01), and IMT (p < 0.01) than that of the patients without hypertension. However, only IT was thicker in patients with smoking (p < 0.05) than that of the patients without smoking. Smoking was associated only with intima while hypertension was associated with the all three layer's thickness. This result suggests the atherosclerotic process can be different by cardiovascular risk factors.

Isotope amount ratios of lead in a bronze sample have been successfully determined using multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS). Matrix separation conditions were tested and optimized using ion exchange chromatography with anion-exchange resin, AG1-X8, and sequential elution of the 0.5 M HBr and 7 M $HNO_3$ to separate lead from very high contents of copper and tin in bronze matrix. Mercury was also removed efficiently in the optimized separation condition. The instrumental isotope fractionation of lead in the MC-ICP-MS measurement was corrected by the external standard sample bracketing method using an external standard, NIST SRM 981 lead common isotope ratio standard followed by correction of procedure blank to obtain reliable isotope ratios of lead. The isotope ratios, $^{206}Pb/^{204}Pb$, $^{207}Pb/^{204}Pb$, $^{208}Pb/^{204}Pb$, and $^{208}Pb/^{206}Pb$, of lead were determined as $18.0802{\pm}0.0114$, $15.5799{\pm}0.0099$, $38.0853{\pm}0.0241$, and $2.1065{\pm}0.0004$, respectively, and the determined isotope ratios showed good agreement with the reference values of an international comparison for the same sample within the stated uncertainties
