This study investigated the effect on children's literacy of teacher-child discussion about the contents of storybooks. The subjects were 10 experimental and 10 control 5-year-old kindergarten children in Cheongju. The experimental design was the Split Plot design. The research instruments used for pre- and post-tests were the Vocabulary Decoding Competence Test(Lee, 1998), Writing Competence Test(Lee & Lee, 1990), Story Comprehension Competence Test(Lee, 1998; Morrow, 1990), and the Emergent Reading Ability Judgements for Favorite Storybooks(Sulzby, 1985). Data were analyzed by ANOVA with repeated measures. Results showed that the teacher-child discussions about the contents of storybooks were effective for improving children's competence in decoding vocabulary, writing, and story comprehension but not for improving emergent reading ability.

The purpose of this study is to investigate the relationships among the beliefs of parents and children, children's cognitive and emotional behavior based on cognitive and interreactionary approach models. The Subjects were 138 children (68 eight-year-olds and 70 eleven-year-olds) and their parents. Instruments used in this study were the modified Family Belief Interview Schedule(Alessandri & Wozniak, 1987), the Standard Achievement Test, and Harter's Perceived Competence Scale. Data analysis was by Pearson's r product moment correlation, two-way ANOVA, Fisher-Z test and Student-Newman-Keuls post-hoc test. The major findings are as follows: (1) The beliefs of parents and children has a significant influence children's perception of competence. (2) The congruence of parents' and children's beliefs was hightest in "assumed similarity". (3) Mother's positive view of their children and congruence of mother's and father's beliefs were correlated with children's academic achievement. Parents' positive beliefs and congruence of beliefs were also correlated with children's self-perception of competence.

This study was conducted to develop and apply a computer-based multimedia nutrition education program for preschoolers based on the Dick and Carey model of instructional design. The Dick and Carey model included 4 phases: analysis, design, development, and evaluation. The program's instructional goals, objectives, assessment instruments, content, examples, and practice questions with feedback were written in the design phase. To be familiar with the 5 food groups, 'Nutrition exploration' were programmed using Hyperstudio. 'Nutrition exploration' was designed as a five-session, interactive multimedia game, with each session taking about 5 minutes to complete. Nineteen preschoolers, aged 6, volunteered to participate formative evaluation. The effectiveness of the program was examined using a pre-post test design. Participants were recruited by personal contact at the individual preschool education center. The application was carried out during 4 weeks. The results showed that intervention participants significantly increased knowledge between pre-test and post-test. The results support using IMM (interactive multimedia) to disseminate nutrition education to the target population. This research provides the basis for continuing development of computer-based nutrition education materials.

Purpose: This study was attempted to verify the effects of Tai Chi exercise on the depression and self efficacy of the patients with rheumatoid arthritis. Method: It employed a non-equivalent control group pre- and post-test design. The research instruments used in this study were depression and self efficacy. Thirty-two patients in the experimental group carried out 50 minutes of Tai Chi exercise for 12 weeks, and 29 patients in the control group did not. Before and after the experiment, both groups were tested for depression and self efficacy. Collected data were processed using the SPSS/WIN 10.0 program analyzing by the frequency, percentage, $X^2$- test, and t-test. Results: Depression significantly decreased in the experimental group. However the improvement in self efficacy of the rheumatoid arthritis patients was not statistically significant but slight enhancement was. Conclusion: Tai Chi exercise is an effective nursing intervention that can be used for rheumatoid arthritis patients.

GUI 테스트 자동화에 대한 연구들이 많이 진행되고 있다. GUI 테스트 하는 방법에 따라 테스트 자동화(Automated Test)와 회귀테스트(Regression Test)가 있는데, 우리는 회귀테스트로 GUI 테스트를 자동화 하려 한다. GUI 자동화 테스트를 위해 시험자동화프로그램으로 테스트 케이스를 시험절차에 따라 생성하고 Dynamic linking library(이하 DLL)의 공유변수마다 GUI 컨포넌트를 정의하여 점검프로그램의 GUI 컴포넌트를 컨트롤 한다. 점검프로그램에서는 DLL 공유변수를 감시하여 해당 GUI 컴포넌트가 On 상태가 되면 기능이 실행되게 구현하였다. 기존의 연구들과 비교하여 최소한의 소스코드 변경과 특정한 툴에 치우치지 않고 통합되어 작동되는 것이 장점이다.

Objectives: To compare the flexural cyclic fatigue resistance and the length of the fractured segments (FLs) of recently introduced M-Pro rotary files with that of RaCe rotary files in curved canals and to evaluate the fracture surface by scanning electron microscopy (SEM). Materials and Methods: Thirty-six endodontic files with the same tip size and taper (size 25, 0.06 taper) were used. The samples were classified into 2 groups (n = 18): the M-Pro group (M-Pro IMD) and the RaCe group (FKG). A custom-made simulated canal model was fabricated to evaluate the total number of cycles to failure and the FL. SEM was used to examine the fracture surfaces of the fragmented segments. The data were statistically analyzed and comparisons between the 2 groups for normally distributed numerical variables were carried out using the independent Student's t-test. A p value less than 0.05 was considered to indicate statistical significance. Results: The M-Pro group showed significantly higher resistance to flexural cyclic fatigue than the RaCe group (p < 0.05), but there was no significant difference in the FLs between the 2 groups (p ≥ 0.05). Conclusions: Thermal treatment of nickel-titanium instruments can improve the flexural cyclic fatigue resistance of rotary endodontic files, and the M-Pro rotary system seems to be a promising rotary endodontic file.
