본 논문에서는 전문 안무가와 일반인들을 대상으로, 현대적 스타일의 독무와 임의적으로 움직이는 육면체를 제시할 때의 두뇌 활동 양상을 fMRI를 통하여 알아보았다. 피험자들은 총 8명으로 구성되었으며, 4명은 안무 전문가들, 4명은 동일한 연령대의 일반인들이었다. 피험자들은 시각 자극으로 제시되는 춤동작과 다양하게 변화하는 단순한 육면체의 움직임을 아무런 반응 없이 보는 과제를 수행하였다. 두 피험자 그룹 모두에서 육면체의 움직임보다 무용을 응시할 때 occipital cortex에서 더 큰 활성화를 보였고, 특히 좌측 STS와 angular gyrus사이의 경계선 영역, 그리고 좌측 fusiform gyrus에서는 안무가들이 무용을 볼 때 일반인들보다 더 높은 활성화를 나타내었다. STS/angular gyrus와 fusiform gyrus가 시각 자극의 의미 표상을 이해하는데 관련이 있고, angular gyrus가 사전적 의미 해석에 있어 중계적 역할을 하는 곳이며, fusiform gyrus는 사물을 지각하는데 있어서 보조 역할을 맡고 있다는 논의를 바탕으로, 무용가들은 그들이 지니고 있는 안무에 대한 전문적인 소견과 지식을 이용하여 몸의 움직임을 분석할 수 있고, 또 그것에서부터 어떠한 상징적인 의미까지 끌어내어 결과적으로 의미 추출의 과정에서 두뇌의 semantic network를 활성화시킨다고 볼 수 있다.

This study examines the concept and related technologies of the 4th industrial revolution that has been mixed so far and examines the socio-economic changes and influences resulting from it, and the cases of responding to the 4th industrial revolution in major countries. Based on this, by deriving SWOT factors and calculating the importance of each factor for Korean venture companies to prepare for the forth industrial revolution, it was intended to help the government and policymakers in suggesting directions for establishing related policies. Furthermore, the purpose of this study was to suggest a direction for securing global competitiveness to Korean venture entrepreneurs and to help with basic and systematic analysis for further academic in-depth research. For this study, a total of 21 items derived through extensive literature research and data research to understand what are the necessary competency factors for internal and external environmental changes in order for Korean venture companies to have global competitiveness in the era of the 4th Industrial Revolution. After reviewing SWOT factors by three expert groups and confirming them through Delphi survey, the importance of each item was analyzed by using AHP, a systematic decision-making technique. As a result of the analysis, it was shown that Strength(48%), Opportunity(25%), Threat(16%), Weakness(11%) were considered important in order. In terms of sub-items, 'quick and flexible commercialization capability', 'platform/big data/non-face-to-face service activation', and 'ICT infrastructure and it's utilization' were shown to be of the comparatively high importance. On the other hand, in the lower three items, 'macro-economic stability and social infrastructure', 'difficulty in entering overseas markets due to global protectionism', and 'absolutely inferior in foreign investment' were found to have low priority. As a result of the correlation verification by item to see differences in opinions by industry, academia, and policy expert groups, there was no significant difference of opinion, as industry and academic experts showed a high correlation and industry experts and policy experts showed a moderate correlation. The correlation between the academic and policy experts was not statistically significant (p<0.01), so it was analyzed that there was a difference of opinion on importance. This was due to the fact that policy experts highly valued 'quick and flexible commercialization', which are strengths, and 'excellent educational system and high-quality manpower' and 'creation of new markets' which are opportunity items, while academic experts placed great importance on 'support part of government policy', which are strengths. The implication of this study is that in order for Korean venture companies to secure competitiveness in the field of the 4th industrial revolution, it is necessary to have a policy that preferentially supports the relevant items of strengths and opportunity factors. The difference in the details of strength factors and opportunity factors, which shows a high level of variability, suggests that it is necessary to actively review it and reflect it in the policy.

2015 개정 교육과정에서 컴퓨팅 사고력의 함양을 강조하고 있지만 컴퓨팅 사고력을 평가하기 위한 도구에 대한 개발이 미흡하다. 비버 챌린지 문항은 전 세계 60여개국의 정보 교육 전문가 집단이 약 1년 동안 공동 출제 및 검토를 통해 개발되는 문항이므로 문항의 타당도가 높다고 볼 수 있다. 다만 초기의 개발 목적이 평가도구로써 사용하기 위함이 아니었기 때문에 과연 컴퓨팅 사고력의 평가 도구로 사용할 수 있는 신뢰도를 가진 문항인가를 검증하기 위해 본 연구에서는 비버 챌린지 2017 그룹 III의 문항을 대상으로 문항내 적일관성신뢰도를 통계적으로 검증하였으며 그 결과 Cronbach ${\alpha}=.784$로 신뢰도가 높게 나타났다.

In this paper, we attempted to provide the bases of effective educational programs for fostering ICT competencies of gifted students in science. For this purpose, we tried to answer the questions like 'What are the ICT core-competence for gifted students in science?' and 'How can we educate those competencies effectively?' We started by reviewing existing studies on ICT competencies for talented people in future society and then adopted one[6] as the basis for further validation. We tried to work with as many G/T experts as possible, and decided to use the online survey methodology because the experts are scattered all over the country. The survey was sent to the corresponding person who is in charge of G/T education in each area, and then e-mailed to G/T experts in that area. Through these procedures, three hundred four(304) G/T experts from all around the country participated in this survey. The results showed the followings: (1) G/T experts agreed with the importance and necessity of ICT competencies for gifted students in science; (2) G/T experts agreed with the validity of three core ICT competencies, which are 'knowledge and skills competence, creativity competence, and characteristic competence,' for gifted students in science; (3) G/T experts agreed with the validity of educational goals, which are suggested for fostering each ICT core-competence of gifted students in science; and (4) G/T experts regarded 'product-oriented education' and 'ICT device-oriented education' as important and effective types of education programs for fostering ICT competencies of gifted students in science.

간암은 세계적으로 흔한 악성 종양에 속하지만 우리나라에서 간암은 위암, 폐암 다음으로 높은 사망률을 보이며 이러한 간암은 조기진단이 요구된다. 전문의는 간암의 진단을 위해 조영증강 CT영상을 이용하여 육안으로 간암을 판별하는데, 조영증강 CT영상을 이용한 진단은 주 종양의 진단에는 도움이 되지만 주 종양에서 주위 간 조직으로 전이된 간암들을 판별하는 것은 어려우며 실제로 시술 중에야 전이된 간암의 존재를 알 수 있다. 본 논문에서는 조영증강 CT영상을 이용하여 간과 주 종양을 자동으로 추출한 후, 미세하게 주 종양 주위로 전위된 간암들을 추출하는 방법을 제안하여 전문의를 보조할 수 있는 보조 전문가 시스템으로서의 유용성을 확인하고자한다. 조영증강 CT영상은 흉부에서 5mm간격으로 40 ${\sim}$ 50장정도로 촬영된다. 조영증강 CT영상을 이용하여 간 영역을 추출하기 위해서 간의 형태학적 정보 그리고 명암도와 명암의 분포도를 이용한 양자화 기법 등을 적용하여 추출하며 추출된 간 영역에서 간암의 후보 영역 추출은 간암의 명암도와 형태학적 특징 정보를 이용하여 추출한다. 본 논문에서는 간암의 추출을 위해 맵 상에 흩어져 분포되어 있는 유사 패턴들의 무게 중심을 찾아 하나의 패턴으로 그룹화 하는 개선된 SOM 알고리즘을 제안하여 간암 판별에 적용한 후, 기존의 SOM 알고리즘과 비교 분석한 결과. 본 논문에서 제안된 SOM 알고리즘을 적용한 간암 추출이 더 효율적임을 확인 할 수 있었으며, 전문의가 판별한 것과 비교 분석한 결과, 전문의를 보조할 수 있는 보조 전문가 시스템으로서의 가능성을 확인할 수 있었다.

This study compared the health behaviors, health related clinical characteristics between individuals with Glycated Hemoglobin A1C≧6.5% and < 6.5% in 30~59yr. Factors that were associated with A1C were identified by sex, health behaviors, health literacy. This study was an observational study with a cross-sectional design based on data from 2019~2021 Korea National Health and Nutrition Examination Survey. Multiple logistic regression analysis was employed to compute the odds ratios of health behaviors to identify the risk factors for Glycated Hemoglobin. The prevalence of A1C≧6.5% among the total was 79.4%(weighted %, n=348). In the A1C≧6.5%, 71.8% were men. In univariate logistic regression for A1C≧6.5%, sex, duration with diabetes, and body mass index(BMI) were influencing factors. In multiple logistic regression by sex, the factors associated with A1C≧6.5 in women were as follows: education(OR 4.5; 95% CI:1.1, 18.5), duration with diabetes(OR 2.9; 95% CI 1.1, 7.9). Strategies should be targeted to improve health behaviors and clinical characteristics for those in their sex, women in low education level, duration with diabetes. Moreover, healthcare providers should understand the barriers to health behaviors and health literacy to effectively deliver healthcare service.
