  • The purpose of this study was to investigate children's perception of reading. The researchers interviewed 120 children aged 5 to 7 (40 for each age group) by using a specially designed interview format. The study of Johns (1973) was referred to as a guide in preparing the format. Responses of the children were classified in accordance with criteria worked out on the basis of the researchers' previous studies and analyzed in terms of frequencies and percentiles by age group. ${\chi}^2$ test was used to analyze the data. The findings of the study were: (1) The younger the children, the higher the rate of showing no response or of responding only to concrete incidents or things. Older children in general showed higher responses relevant to reading comprehension than younger ones. (2) Older children were more inclined than younger ones to regard the process of reading as a skill-oriented, teacher-based process. (3) Children in these age groups showed little perception of reading's objectives of comprehension and communication.

  • Background: We described a novel multi-step retinal fundus image reading system for providing high-quality large data for machine learning algorithms, and assessed the grader variability in the large-scale dataset generated with this system. Methods: A 5-step retinal fundus image reading tool was developed that rates image quality, presence of abnormality, findings with location information, diagnoses, and clinical significance. Each image was evaluated by 3 different graders. Agreements among graders for each decision were evaluated. Results: The 234,242 readings of 79,458 images were collected from 55 licensed ophthalmologists during 6 months. The 34,364 images were graded as abnormal by at-least one rater. Of these, all three raters agreed in 46.6% in abnormality, while 69.9% of the images were rated as abnormal by two or more raters. Agreement rate of at-least two raters on a certain finding was 26.7%-65.2%, and complete agreement rate of all-three raters was 5.7%-43.3%. As for diagnoses, agreement of at-least two raters was 35.6%-65.6%, and complete agreement rate was 11.0%-40.0%. Agreement of findings and diagnoses were higher when restricted to images with prior complete agreement on abnormality. Retinal/glaucoma specialists showed higher agreements on findings and diagnoses of their corresponding subspecialties. Conclusion: This novel reading tool for retinal fundus images generated a large-scale dataset with high level of information, which can be utilized in future development of machine learning-based algorithms for automated identification of abnormal conditions and clinical decision supporting system. These results emphasize the importance of addressing grader variability in algorithm developments.

  • The purpose of this study was to investigate speech rate and fluency in stuttering adults. It was suggested that a measurement guideline of speech rate and fluency for collecting clinically meaningful data be used. Subjects included 10 adults who stutter (mean age=25;8). Syllables were used as the unit of measurement for analyzing the duration of speech. The mean rate was 241 SPM (syllables per minute) for reading, and 196 SPM for spontaneous speaking. Fluency was also measured in both cases. The correlation between rate of speech and fluency was high (r=0.92). A strong positive correlation was found between different investigators in measuring speech rates and fluencies.

  • Lip-reading technique based on bimodal is to enhance speech recognition rate in noisy environment. It is most important to detect the correct lip-image. But it is hard to estimate stable performance in dynamic environment, because of many factors to deteriorate Lip-reading's performance. There are illumination change, speaker's pronunciation habit, versatility of lips shape and rotation or size change of lips etc. In this paper, we propose the IIR filtering in time-domain for the stable performance. It is very proper to remove the noise of speech, to enhance performance of recognition by digital filtering in time domain. While the lip-reading technique in whole lip image makes data massive, the Principal Component Analysis of pre-process allows to reduce the data quantify by detection of feature without loss of image information. For the observation performance of speech recognition using only image information, we made an experiment on recognition after choosing 22 words in available car service. We used Hidden Markov Model by speech recognition algorithm to compare this words' recognition performance. As a result, while the recognition rate of lip-reading using PCA is 64%, Time-domain filter applied to lip-reading enhances recognition rate of 72.4%.

  • This study analyzed the effectiveness of visiting reading programs for vulnerable children, focusing on the case of libraries in A-si, Gyeonggi-do. Library A utilized a visiting teacher to deliver books that matched the children's levels and interests through non-face-to-face interactions, or to engage in face-to-face reading sessions and deliver books together. In 2022, a total of 158 individuals from 103 families participated in the program, with 103 individuals from 67 families delivering books and 55 individuals from 36 families engaging in book reading activities. Pre- and post-project surveys were conducted to assess the reading effects, and interviews were conducted with the visiting teachers. The analysis revealed that the level and interest of the children during book delivery and reading sessions were identified, and the effects of reading books with high levels of interaction were significant. Infants who were able to easily acquire reading experiences according to their age exhibited better reading effects compared to elementary school students. The program aimed at the new participant group showed slightly greater effectiveness than the group of continuing participants. Furthermore, following the implementation of the program, improvements were observed in reading interest, reading attitude, reading environment, reading interaction, self-esteem, social skills, language ability, reading proficiency, self-directed learning ability, and library utilization rate.

  • The purpose of this study was to analyze the reading materials in 7th curriculum and 2009 revised high school chemistry I textbook for identifying the problems of reading material presented in science textbooks and to investigate science teachers' recognition about utilization reading materials in science textbook. For this purpose, each four 7th curriculum and 2009 revised high school chemistry I textbook were analyzed according to the number of reading materials, the type of contents and the type of students' activities. In addition, the secondary school science teachers' recognition about utilization reading materials in science textbook was investigated. The results were as follows: First, anylizing reading materials in chemistry I textbooks showed that and the rate of reading materials were presented from 7.9 to 17.1% in 7th curriculum and from 20.6 to 28.2% in 2009 revised curriculum textbook. It implies that the rate of reading materials in 2009 revised textbooks increases more than those in 7th curriculum textbook. The result of analyzing the type of contents, 'life sciences' was the largest proportion with 34.3 % in the 7th curriculum chemistry I, but 'enrichment and supplement of knowledge' was the largest proportion with 23.7% in 2009 revised curriculum. Analyzing the type of student activities, only 13% of the reading materials in 7th National Curriculum textbook was found to be inquiry type, but 35% of the reading materials in the 2009 revised curriculum. appears to be inquiry type. It suggested that the curriculum objectives was reflected in the textbook. Second, investigating recognition of teachers' perceptions of utilization science textbooks, 67% teachers responded that they used the reading materials in their science class, but teachers who didn't use the reading materials was almost 33%. A large number of teachers responded that the reading materials associated with the real-life needed for integrated education and thought that the reading materials about 'life and science' should be included in the science textbooks.

  • The study was basically carried out to establish the appropriate condition for applying the Westergren method for erythrocyte sedimentation rate(W-ESR) in Throughbred racehorses at recess. To do this, we examined the correlationship among some factors including the kind of anticoagulants, optimal ambient temperature and reading time for W-ESR in healthy racehorses. The difference between the blood samples treated with only 3.8% solution of sodium citrate(SC) and both EDTA and SC as a coagulant, there was not recognized any significant difference(p<0.05) in the levels of W-ESR irrespective of the ambient temperature of $20^{\circ}C$ or $30^{\circ}C$. The best optimal ambient temperature for W-ESR in horses was proved at $30^{\circ}C$ resulting from the tendency of the most reduced dispersion in mean values analyaed from repeatly 4 times to the same blood samles compared with those of $10^{\circ}C$ and $20^{\circ}C$. The optimal reading time was determined as 60 minutes(Y=237.2~4.1X, $r^2=0.998$) and 70 minutes(Y=247.8~4.2X, $r^2=0.999$) under the same temperature of $30^{\circ}C$; the latter showed the better result on the basis of the correlation of packed cell volume(PCV) and ESR values. About 13 healthy racehorses, we compared the real values of W-ESR respectively obtained at 60 minutes and 70 minutes at $30^{\circ}C$ with the anticipated values of PCV by means of the analysis of linear regression equitation. As the result of this, the strong correlation between both of them was confirmed. For practical use of W-ESR in Thoroughbred racehorese, we can recommend the condition of 60 or 70 minutes for the optimal reading time as well as $30^{\circ}C$ for the best ambient temperature.
