The purpose of this study was to investigate the characteristics of reading, writing fluency of the underachieving children and stuttering children and school-aged children and frequency of errors. The participants were 15 underachieving children and 15 stuttering children and 15 school-aged children without disabilities. All participants were required to conduct reading, writing, speaking tasks. First, work for the reading tasks were different among the underachieving children and stuttering children and school-aged children. Second, writing tasks were not different among the groups in the writing fluency, but it was lacking in accuracy, which is stuttering, speaking fluency as well as their language fluency is suggesting the need for diagnosis and intervention. Third, this type of errors of writing tasks is showed higher levels of ommission, substitution, grammatical errors in the underachieving children group. The therapy of reading of stuttering also consider a treatment program that can be configured in the combined writing tasks.

Library and information service (LIS) of academic libraries plays an important role in the education and research activities of universities. Such importance of LIS facilitated much research that defines the quality factors constituting LIS and identifies the importance of them. The previous literature, however, has some limitations. The limitations arise from the interrelationship among the quality factors and the perception gap between users and providers on LIS quality factors. Despite the understanding of the interrelationship and the perception gap, LIS studies to deal with both dimesions synthetically are sparse. Therefore, this paper defines the interrelationship among LIS quality factors as a network model, then identifies the perception gap on LIS quality factors by exploiting the analytic network process. As an early stage study, this paper contributes to helping the quality improvement of acedemic LIS by considering the interrelationship among LIS quality factors and the perception gap on the LIS quality factors between LIS users and providers.

This study examined differences among high, medium, and low achievers' motivation, self-regulation strategy, and learning style in an online gifted program. The sample included 788 middle and high school students who participated in the 3-months online gifted program. Participants volunteerly completed 60 questions on their motivation, self-regulation strategy use, and learning style. Multivariate analysis of variance(MANOVA) was conducted for data analysis using SPSS 19.0. The results of this study showed that (1) as levels of students' achievement increased, levels of intrinsic motivation increased as well; (2) statistically significant differences also existed on the levels of elaboration strategy, effort management, and time management strategy use among three levels of achievement and (3) no significant differences in students' learning style preference were found between competitive or cooperative learning style. To sum up, high achieving students' levels of intrinsic motivation, elaboration strategy, effort management strategy, and time management strategy use were the highest compared to medium and low achieving students.

학습의 깊이의 단계를 Bloom은 지식, 이해, 적용, 분석, 종합, 평가라는 6가지의 단계로 나누면서 피상적인 학습과 감이 있는 학습으로 구분하였다. 최근 학습은 면대면 학습에서 뿐 아니라, 웹기반의 학습에서도 피상적인 학습 위주로 이루어진다는 비판을 받고 있고, 웹기반 학습에서는 자기조절 흑은 자기규제의 문제가 가장 큰 문제로 지적 받고 있다. 본 연구에서는 이를 해결하기 위한 방안으로서 감이 있는 학습을 촉진하고, 자기 조절을 촉진하는 메타인지를 웹기반학습에의 인터페이스 디자인에 적용하는 문제를 살펴보았다. 이를 알아보기 위해 메타인지 전략의 가장 핵심 요소인 '자기 점검'의 요소 중 학습 내용들 간의 위계 관계를 보여주는 지도 (MAP) 와 계획세우기를 도와주는 요소 (PLAN)를 기존 연구를 토대로 웹기반의 학습의 인터페이스로 구현하고, 이러한 요소들이 학습, 특히 Bloom이 말한 김이 있는 학습을 촉진하는지를 실험을 통해 살펴보았다. 메타인지를 활용한 웹기반 학습의 효과는 배운 내용의 사후 테스트 점수로 측정되었다. 일반적으로 웹상에서 이루어지는 학습의 일반적인 형태인 학습 중에 확인문제를 푸는 조건 (OX조건)과 확인문제와 학습 내용들 간의 위계 관계를 보여주는 지도를 제시하는 조건 (MAP조건), 이에 덧붙여 사전 계획세우기까지 모두 하는 조건 (PLAN조건)으로 나누어 실험이 진행되었다. 그 결과 첫째, 집단 간 참가자들의 전체적인 학습 점수는 MAP조건이 가장 낮고, OX조건이 중간, PLAN조건이 가장 높은 모습을 보였다. 그러나 이 차이가 통계적으로 유의미하지는 않았다. 또한 모든 조건의 집단에서 행해졌던 학습 중간의 OX점수는 집단별 점수의 차이가 통계적으로 유의미하지는 않았으나, 평균의 차이를 보여주었다. 둘째, 조건별 참가자의 학습 효과는 피상적인 학습수준(암기)에서는 통계적으로 집단 간 유의미한 차이를 보였다. 그러나 감이 있는 수준의 학습(문제해결)에서는 집단 간에 통계적으로 유의미한 학습의 차이를 보이지 않았다. 따라서 깊이있는 학습을 촉진하는 웹기반 학습의 인터페이스 디자인에 대해서는 추후 연구가 필요하다.

Genetic diversity and population genetic structure were estimated in nine natural populations of Exochorda serratifolia in South Korea using ISSR marker system. Average of polymorphic loci per primer was 5.8 (S.D.=2.32) and percentage of polymorphic loci per population was 78.7% with total 35 loci from 6 ISSR primers. In AMOVA, 27.8% of total genetic variation came from genetic difference among populations and 72.2% was resulted from difference among individual trees within populations. Genetic differentiations by Bayesian inference were 0.249 of ${\theta}^{11}$ and 0.227 of $G_{ST}$. Inbreeding coefficient for total populations was 0.412. There was significant correlation between genetic distance and geographic distance among populations. On the results of Bayesian cluster analysis, nine populations were assigned into three groups. The first group included 5 populations, and the second and the third had two populations per group, respectively. These three regions could explain 10.0% of total genetic variation from hierarchical AMOVA, and the levels of among-population and among-individual were explained 19.7% and 70.3%, respectively. The geographic distribution of populations following the three Bayesian clusters could be explained with mountain range as Baekdudaegan which is the main chain of mountains in Korea. The mountains as the physical barrier might hamper gene flow in the pearlbush. So when protected areas are designated for conservation of this species, we should consider those three regions into considerations and would better to choose at least one population per region.
