지난 2001년 골드만삭스는 선진국 이후 세계 경제를 이끌어갈 새로운 성장동력으로 자리잡을 국가로 BRICs를 제시했다. IBRICs란 Brazil, Russia, India, China와 같은 신흥개발도상국을 뜻한다. 이후, 유망시장을 의미하는 신조어들이 많이 나왔었는데, HSBC은행이 작년에 제시한 CIVETS(시베츠) 국가가 최근에 각광을 받고 있다. CIVETS 국가는 Columbia(콜롬비아), Indonesia(인도네시아), Vietnam(베트남), Ezypt(이집트), Turkey(터키), South africa(남아프리카 공화국) 등 6개국을 뜻한다. 아직은 BRICs 국가들에 비해서 경제규모는 작지만 풍부한 젊은 인구, 빠른 경제성장을 바탕으로 BRICs 이후로 유망 국가로 부상하고 있는 국가들이다. 그럼 각 나라별로 어떤 특징을 갖고 있는지 살펴보기로 하자!

블록체인 기반 온라인 거래 플랫폼은 중개자에 의존적인 기존의 거래 방식을 탈피하여 비용 및 시간의 낭비를 줄이고 참여자들 간의 신뢰성 있는 직접적인 거래를 실현시켰다. 하지만 비허가형 블록체인은 참여자들의 프라이버시를 제공하지 못하는 문제가 있다. 본 논문에서는 허가형 블록체인인 하이퍼레저 패브릭을 사용하여 프라이버시를 강화한 디지털 콘텐츠 저작권 보호 및 거래를 위한 블록 체인 플랫폼을 제안한다.

This paper presents the line contention avoidance experiments with an optical switch, which was selected based on the comparison analysis and evaluation of the various characteristics. For example, the function, structure, strengths and weaknesses of the optical switches. After considering the nonblocking, modularity, upgrade ability and optical power loss of the several kind of the switch fabrics, a switch was selected. The selected switch fabric by using wavelength converters was controlled to avoid contention of the optical lines. In this experiment shows an example of three cases. As a result of this experiment, optical signal shows a changed peek of optical power in output. By showing a peak it confirms that the contention was avoided. By analyzing of changed optical power according to the channel setting time and release time to control of the switch could be determined. If this analysis applied to the network design, economical and efficient structures can be formed.

The goal of this study is to suggest evaluation tools to assess computational thinking(CT) skills in primary robot-based programs. In addition, the researcher has expanded its evaluation approaches to include interpersonal competencies from the socio-cultural perspectives, not just focusing on intrapersonal competencies. In order to pursue the research goal, one-semester robots programs for the fifth graders were designed, and evaluation tools including a learners' CT competencies survey and a learning process monitoring rubric were developed. The results of this study are meaningful because it has expanded the evaluation approaches to connect to the concepts of CT and to include interpersonal aspects from the socio-cultural perspectives.

Purpose: To evaluate the applicability of Lasater Clinical Judgment Rubric (LCJR) as an evaluation tool for hypoglycemia simulation practicum on Korean nursing students. Methods: The methodological study was done to evaluate the reliability and validity of the LCJR. Based on Benner's 4 levels of nursing grading rubric, ten items of the LCJR was evaluated for interrater reliability and internal consistency. The content validity was tested by eight experts and concurrent validity was done by Clark (2006)'s clinical simulation grading rubric. Fifty five video-taped cases of senior nursing students in Y University were used for the reliability and concurrent validity of the LCJR. Results: The interrater reliability was r=.90 (p<.001); Kendall tau b=.87 (p <.001), and Cronbach's alpha was .90. A value of item content validity index of the LCJR was .97 and correlation coefficient between the LCJR and Clark's instrument was .90 (p<.001). The mean (${\pm}SD$) of the nursing students' clinical judgment was 2.04 (${\pm}50$). Conclusion: The LCJR is a useful tool to examine the simulation performance evaluation for improving competency among nursing students. The results indicated that the LCJR may provide valuable information regarding clinical judgment of nursing students and thus, suggested to use to develop a simulation-based education program.

This paper evaluates the achievement of program outcomes using course-embedded assessment for information security programs. In the case study concerning the development of course-embedded assessment used in this paper, we evaluate program outcomes using various evaluation tools including the course evaluation data. In addition, we consider the evaluation rubric and evaluation procedure for course-embedded program outcomes, set performance criteria, select the probe course with high contribution to the program outcomes according to curriculum flowchart, set course objectives for the probe course, and explain the rubric for each assessment tool to measure achievement level. Subsequently, we perform course-embedded program outcomes assessment, based on tests and projectevaluation tool for each program objectives, and present the achievement levels based analysis results. These results prove the effectiveness of the proposed course-embedded assessment for program outcomes.

The purpose of this study is to analyze daylight distribution and characteristics of light on the Korean traditional paper and to investigate a possibility as the shading systems. First of all, daylight distribution through the Korean traditional paper windows and doors of the Traditional House is analyzed at Genjaegotaek of the Asan Oeam Traditional Village. After making a model, the characteristics of light on the Korean traditional paper and Roller Shade fabric are analyzed Korean traditional paper has a good efficiency to diffuse the light and is less glare than Roller Shade fabric. In the present office buildings and apartmant houses, daylight characteristics of the Korean traditional paper windows and doors could be used as preliminary data to develop a window system which makes greatest performance of daylight.

Recently, the optical subscriber interface module uses the high performance network processor to quickly develop new application services such as MPLS, VPN, RPR and EPON with a short time-to-market. Although a number of vendors are developing the network processor at 2.5Gbps, only the IBM NP4GS3 can provide packet processing with wire-speed at 2.5Gbps. IBM NP4GS3, however, uses its unique speed DASL interface instead of CSIX-Ll interface, which has standardized by M: Forum currently Therefore, we implement an interconnection mechanism to use the switch fabric with CSIX-Ll interface. In this paper, we suggest the architecture and a packet control mechanism supporting interconnection between IBM NP4GS3 DASL and CSIX-Ll switch interface using the common IBM UDASL ASIC and XILINX FPGA.

The objective of this paper is an implementation of analysing and predicting functions to promote self-directed learning for student's performance assessment system in programming subjects. By adapting Rubric model, the proposed functions inform a student of the assessment criteria and level to be carried out with respects to two-way specifications such as rational ability, problem solving ability and creativity. The proposed system also provides a graphical results of each ability instead of assessment result, for better understanding and analyzing himself/herself based on to the performance assessment and the result. Moreover, the proposed system contains a method to predict future achievement result with moving average technique. Therefore, an academic achievement can be precisely determined by himself/herself to estimate self-directed learning. The teacher can provide different level of educational resources such as supplement learning, problem explains and private instructor etc., in order to maximize efficiency of education.
