Jenny Young-Loveridge, Brenda Bicknell 환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 17 Pages
환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2015, Vol.9 No.3 3 27-43 (17 pages)
This paper examines children’s number fact knowledge in relation to mathematics problem solving. These findings are derived from a study that set out to explore the impact on mathematics learning of using multiplication and division contexts with 84 five- to seven-year-old children from diverse cultural and linguistic backgrounds. After a series of focused lessons, children’s knowledge of number facts, including single-digit addition, subtraction, and doubles improved substantially. However,... -

부분집합 합 문제는 유한개의 정수로 이루어진 집합이 있을 때 이 집합의 부분집합 중에서 그 집합의 원소들의 합이 특정 값이 되는 경우가 있는지를 알아내는 문제로, 잘 알려진 다항식 시간 내에 풀기 어려운 NP-완비 문제이다. 유전 알고리즘은 선택과 교차, 돌연변이 등의 연산을 통해 주어진 문제의 최적해를 구하는 알고리즘이다. 동적 계획법은 주어진 문제를 풀기 위해서 문제를 하나 또는 여러 개의 하위 문제로 나누어 풀이하는 방법이다. 본 논문에서는 부분집합 합 문제를 풀이하는 유전 알고리즘을 설계 및 구현하고, 답을... -
Fast Nearest-Neighbor Search Algorithms Based on High-Multidimensional Data
Rosslin John Robles 인문사회과학기술융합학회 예술인문사회융합멀티미디어논문지 8 Pages
인문사회과학기술융합학회 예술인문사회융합멀티미디어논문지 2013, 제 3권 제 1호 3 17-24 (8 pages)
Similarity search in multimedia databases requires an efficient support of nearest-neighbor search on a large set of high-dimensional points as a basic operation for query processing. As recent theoretical results show, state of the art approaches to nearest-neighbor search are not efficient in higher dimensions. In our new approach, we therefore pre-compute the result of any nearest-neighbor search which corresponds to a computation of the voronoi cell of each data point. In the second step, we... -
The Social Stress-Buffering Role of Exchanging Emotional Support in an Online Breast Cancer Support Group

This study examined the social stress-buffering functions of expression and reception of emotional support in an online breast cancer support group. The data used in the analysis resulted from merging computer-aided content analysis of discussion posts, action log data analysis of system usage, and longitudinal survey data collected from 237 participants in an online breast cancer support group. Findings indicated that the expression and reception of emotional support buffered the deleterious... -
Effects of Using Picture Books on Reading Self-Perception Among Year Two Pupils at A National-type Chinese Primary School

환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2021, Vol.15 No.2 8 161-186 (26 pages)
Pupils who feel good about their reading abilities tend to perform better in school. Research has shown that picture books will contribute to pupils taking the initiative to read. The purpose of this study was to examine the effects of picture books on reading self-perception among Year Two pupils at a National-type Chinese Primary School in Hulu Selangor. This study employed a quasi-experimental research with pre-test and post-test designs that involved 75 pupils and four picture books, namely,... -
Assessment of Teaching Aptitude of Preservice Teachers Enrolled in University-Based Teacher Credential Programs in South Korea: Providing Diagnostic Information Based on a Cognitive Diagnostic Assessment Framework
Yi Hyun Sook, Park Sejin 한국교육학회 교육학연구 27 Pages
한국교육학회 교육학연구 2022, 60권 3호 1 1-27 (27 pages)
Teacher education programs must provide opportunities for student teachers to explore their teaching aptitude early in the program and help them to strengthen their areas of weaknesses to prepare them for the realities of teaching. This study employed the cognitive diagnostic assessment framework, which is known to be effective in providing profiles of multidimensional and inter-related attributes, such as the teaching aptitude. The attribute mastery profiles of 1,111 participants from 6 South... -
A Comparison of Three Bayesian Point Estimates for Cross-Classified Multiple Membership Growth Curve Modeling
Chung Hyewon, Jeon Hyeonjeong, Park Soyoung 한국교육학회 교육학연구 26 Pages
한국교육학회 교육학연구 2021, 59권 7호 7 167-192 (26 pages)
This simulation study evaluated parameter recovery in cross-classified multiple membership growth curve modeling under a variety of manipulated conditions, including prior distributions (inverse Wishart and uniform distributions), number of measurement occasions (3, 5), number of groups (30, 50, 100), average group size (20, 40), and non-pure hierarchical data rates (20%, 40%). Three Bayesian point estimates were compared: the posterior mean, the posterior median, and the posterior mode. With... -

최근 즐거움과 학습 효과를 동시에 제공하는 교육용 기능성 게임이 많은 주목을 받고 있다. 그러나 대부분의 교육용 게임들을 유아나 아동들을 대상으로 하고 있고, 고등 교육에서 이러한 게임을 활용하는 것은 여전히 어려운 실정이다. 반면, 본 논문은 대학생들에게 수리계획법을 가르치는데 활용할 수 있는 교육용 게임을 개발하고자 한다. 잘 알려져 있듯이, 대부분의 퍼즐 게임들은 연관된 최적화 문제로의 변형이 가능하며, 본 논문에서는 부분집합총합문제 기반 교육용 퍼즐 게임을 제안한다. 이 게임은 사용자가 퍼즐을... -

In recent years, a number of CEOs of big Korean conglomerates are being prisoned or sentenced longer period than ever before. Legally, since executive officer system was introduced, executive function of BOD has been separated and appeared to more focus on supervisory function. In addition, in terms of directors’ responsibility, legislative policies, which strengthen, alleviate or decrease that responsibility by taking account of the specialty of position of directors, have been considered....
