본 논문에서는 DigComp를 분석하여 데이터 리터러시 수준을 분석하고자 하였다. 이를 위해 DigComp의 구성요소인 데이터 리터러시, 소통 및 협업, 디지털 콘텐츠 제작, 보안, 문제해결 중 데이터 리러터시 영역의 세부 요소를 살펴보았다. 데이터 리터러시는 탐색·검색·필터링, 평가, 관리 3가지로 세분되어 있었고, 각각은 수준에 따라 기초, 중급, 고급, 전문가의 4단계로 구분되어 있었다. 그리고 3가지 영역의 수준을 분석하여 각 수준을 대표하는 핵심 단어를 추출하였다. 향후 이를 바탕으로 한 구체적 적용방안에 관한 연구가 이뤄지길 기대한다.

This paper aims to provide empirical evidence required to describe the level of achievement by analyzing students' item response in NAEP implemented in the United States in 2001. The geography assessment in the NAEP is aimed to test students of 4th, 8th, and 12th grades, and consists of content dimension and cognitive dimension, The former includes 'space and place' 'environment and society' and 'spatial dynamics and connections,' and the latter includes 'knowing' 'understanding' and 'applying,' The level of achievement is defined as three levels for each grade: Basic, Proficient, and Advanced. In this paper, descriptions of achievement is derived inductively from an analysis of student's responses to the items which were selected by using item-mapping method. As a result, there is a great difference between the level of achievement derived empirically from students' response and the level of achievement designed principally suggested by the expert committee. The former could have a contribution to the improvement in geography curriculum.

The purpose of the research was to identify the level of accounting information system for SMBs and environmental factors, and to analyze whether the level of accounting information system affects system performance. The research method measured the AIS level using Nolan's growth phase model, and the verification of the factors affecting the situation, AIS level, and performance was verified using the regression analysis model. The results of the study are summarized as follows: In measuring the level of an accounting information system, it was found that it was in the stage of integration, which is Step 4, and the analysis of the factors influencing the level of an accounting information system showed that the uncertainty in the environment was absolutely affected.

How a pre-service teacher understands and comments on mathematics instruction can serve as the foundation of her teaching expertise. Given that prospective teachers observe demonstrative mathematics teaching implemented by an in-service teacher and make a comment on it during their practicum period, this paper specified the levels of their ability in commenting on mathematics instruction and explored the characteristics of such levels. It is significant that this paper provides a systematic and comprehensive analysis of such levels in terms of topic, agent, stance, evidence, and alternative perspective. The results of this study showed that the commenting levels may be classified by Level 1 (fragmentary), Level 2 (inspective), and Level 3 (analytical), and that the most frequent level of this study was at Level 2. Multiple regression analysis demonstrated that stance is the most influential in determining the levels of comments among their analytic components. An analysis of the participants' anecdotes showed that the experience of observing demonstrative teaching during the practicum may have impact on the belief of mathematics instruction and self-image as a teacher. Building on these results, this paper provides implications of teacher preparation programs to enhance prospective teachers' ability to analyze elementary mathematics lessons.

이 연구의 주된 목적은 IMF 외환위기를 계기로 사회경제적 차별출산력의 양상이 어떻게 변화하였는가를 파악하는 것이다. 이 연구는 2003년 전국출산력조사 자료를 활용하여 20-49세 기혼 여자의 총출생아수와 1998년 이후의 출생아수를 비교분석하였다. 또한, 분석대상을 1997년 이전에 결혼하였거나 재혼한 부인들과 1997년 이후 처음 결혼한 부인들의 두 집단으로 구분하여 출산력 수준과 출산행태를 비교함으로써 IMF 외환우기 이전과 이후의 변화양상을 파악하고자 시도하였다. 총출생아수에 대한 분석 결과. 부부의 사회경제적인 조건과 출산수준은 대체로 뒤집어진 J 자형의 관계를 유지하는 것으로 밝혀졌다. 즉 사회경제적 지위가 높아질수록 출산수준이 낮아지는 경향이 발견되었다. 그러나 사회경제적 지위가 가장 높은 집단은 바로 밑의 집단 보다 출산수준이 상대적으로 높았다. 그런데, 최근의 출산수준은 이러한 사회경제적 차별출산력과는 뚜렷하게 대조적인 양상을 나타냈다. IMF 외환위기 이후 출산수준 감소의 폭은 기존의 출산수준과 정비례하는 방식으로 미루어졌다. 출산수준이 높은 집단일수록 급속한 출산력 저하가 이루어졌으며 출산수준이 낮은 집단에서는 상대적으로 변화가 완만하였다. 그 결과, 최근의 출산수준은 중상층에 해당하는 사회경제적 지위를 지닌 집단이 가장 높고, 다음이 최상위 집단, 그리고 하위 집단의 순으로 바뀌었다. 이러한 경향은 부부의 교육수준, 직업, 종사상 지위, 주관적 계층에 따른 최근 출산력의 변화양상에서 일관적으로 나타났다.

The purpose of this study is to assess the smart city for major cities in Korea. The assessment indicators are based on the STIM structure (Service, Technology, Infrastructure, and Management Layer Architecture) of the Multi-Layered Smart City Model. Assessment indicators are established through smart city concepts, case analysis, big data analysis, as well as weighted through expert AHP survey. For the assessment, seven major metropolitan cities are selected, including Seoul, and their data such as KOSIS, KISDISTAT from 2017 to 2019 is utilized for the smart city level assessment. The smart city level results show that the service, technology, infrastructure, and management levels were relatively high in Seoul and Incheon, which are metropolitan areas. Whereas, Busan, Daegu, and Ulsan, the Gyeongsang provinces are relatively moderate, while Daejeon and Gwangju, the South Chungcheong region and the Jeolla provinces, were relatively low. The overall STIM ranking shows a similar pattern, as the Seoul metropolitan area smart city level outperforms the rest of the analyzed areas with a large difference. Accordingly, balanced development strategies are needed to reduce gaps in the level of smart cities in South Korea, and respective smart city plans are needed considering the characteristics of each region. This paper will follow the literature review, assessment index establishment, weight analysis of assessment index, major cities assessment and result in analysis, and conclusion.

Mutation testing is known as a very useful technique for measuring the effectiveness of a test data set and finding weak points of the test set. An equivalent mutant degrades the effectiveness of mutation testing. Elimination of equivalent mutants is a very important problem in mutation testing.In this paper, we proposed kinds of methods for detecting class-level equivalent mutants. These methods judge the equivalency of mutants through structural informations and behavioral information of the original program and mutants using static analysis. We found that our approach can detect not a few of equivalent mutants and expected that the cost of mutation testing can be saved considerably.

The results analysis of National Assessment of Educational Achievement(NAEA) can provide various implications for teaching and learning in the school field. In this study we analyzed the deviation of NAEA achievement level-based correct-answer rate and the distribution of the responses percentages for three years from 2015 to 2017 focused on multiple-choice items. First we calculated the deviation of correct-answer rate between advanced level and proficient level and between proficient level and basic level, and then we selected the items whose deviation of correct-answer rate is more than the third quartile. We explored what the content areas, behavior areas and achievement standards of each item are and what the achievement standards and characteristics of these questions are. Based on the results of the analysis, we intended to derive implications for appropriate teaching-learning methods at each achievement-level.

최근 국내에서 신 변종 공격이 대량으로 발생함에 따라, 한정적인 보안전문 인력과 기존의 장비로 분석 및 대응하는데 어려움이 있다. 본 논문에서는, 대량으로 발생하는 침해사고에 대해 분석 우선순위를 확인하고자, 침해사고에 활용된 침해지표들의 위협을 분석하고 이를 정량적인 값인 침해지표 위협수준(TL_IoC, Threat Level of IoC)로 도출하는 방안을 제안한다. 이를 통해, 침해지표의 위협수준을 직관적으로 확인함으로써 침해사고의 대응수준을 신속하게 판단하고, 위협수준이 높은 침해사고에 대해 능동적으로 빠르게 분석함으로써 대량의 침해사고를 효율적으로 대응할 수 있다.
