Analyzing research schools' reports on school library activities, this paper identifies the characteristics and problems of library assisted instruction (LAI), and proposes areas and ways for improvement. Twenty three reports of secondary schools in Edunet were analyzed and their content were categorized into 13 educational activities. Most frequently implemented activities were collection development, reading programs, LAI, and Digital Library System (DLS). The verified positive impact of LAI include enhanced motivation for reading and improved ability for self-directed learning. Areas for improvement include LAI's excessive dependence on DLS and reading activities, insufficient time and library materials which hindered students' information activities. In order for LAI to be more effective in enhancing self-directed learning ability, it is suggested to connect LAI to specific educational experiences and develop customized and detailed content.

The constraints of printed text have been lifted through developments in computer technology which has been identified as a revolutionary force. Hypertexts can be simply defined as electronic text that is found online, in a non-linear manner. In contrast to traditional printed texts, electronic writing depends upon an emergent technology, which is still subject to transformation. Unfortunately more research is needed on the experiences readers have when reading documents in hypertext formats for the purpose of knowledge retention. This study is to research the contrast between the traditional printed texts and hypertexts. Other areas where the literature has been relatively silent will be explored such as the experiences subjects have in reading hypertexts, and printed texts. It was clearly founded that the format of text does significantly influence the recall comprehension level of readers in the Printed Text and Hypertext Groups.

The current research has investigated the effect of school-aged children's TV viewing on their creativity, and examined the moderating effect of book reading in the relationship between children's TV viewing and creativity. Using data from the 10th (2017) Panel Study on Korean Children, the relationship between 9-year-old children's TV viewing, book reading, and performance on Korean Figural Creativity Test for Elementary school Student (K-FCTES) was examined. There was a significant negative correlation between children's TV viewing and creativity, and a positive correlation between children's book reading and creativity. In addition, children's TV viewing had a significant negative effect on their creativity, and children's book reading moderated this relationship. This study has its significance in that it identifies the negative effects of media exposure that needs be considered for creativity development of today's children, who are growing as digital native from birth, and it shows the importance of book reading as a factor that can control the negative effects of TV exposure.

Lip-reading technology that is studied them is used to compensate speech recognition degradation in noise environment in bi-modal's form. The most important thing is that search for correct lips area in this lip-reading. But, it is hard to forecast stable performance in dynamic environment. Used RASTA filter that show good performance to remove noise in the speech to compensate. This filter shows that improve performance of using time domain of digital filter. To this experiment observes performance of speech recognition only using image information, service chooses possible 22 words and did recognition experiment in car. We used hidden Markov model by speech recognition algorithm to compare this words' recognition performance.

Recently, several papers for reading meters remotely using RFID/USN technologies have been presented. In the case of water meter, there has been neither commercial product nor paper. In this paper, we describe the design and implementation of wireless digital water meter with low power consumption. We use magnetic hole sensors to compute the amount of water consumption. The meter of water consumption is transferred via ZigBee wireless protocol to a gateway. Low power consumption design is essential since a battery should last till the life time of water meter. We present that dual batteries haying 3V, 3000mAh, would last 8 years by analyzing the real power consumption of our water meter.

The full-field digital mammography (FFDM), which has been known as a digital breast imaging system, carries out more outstanding performance than the screen-film mammography in overall image quality, skin & nipple, description of pectoral muscle and expression of micro-calcification. Thus, in this thesis, I perform experiments for both the enhancement of image quality and accurate estimation of the result in question, when detecting the very tiny-sized lesions in mammography. The image of digital breast X-rays is the important diagnostic tool for detecting early breast cancer and micro calcification lesion. The experiment of how much compression rate has an effect on the result of diagnosis in the case of microcalcification lesion, with JPEG2000 40:1 compression and over 50% enlargement led to obscure or definitely unacceptable diagnostic results is performed. And in another study of assessment of PSNR degree. I recognized the importance of standardized management system in mammography, where not to mention the accurate reading of the image has the most crucial role in diagnosis

This study aims to secure basic data for the development of locally customized reading culture programs by closely examining and analyzing the reading practices of local library users, their evaluation and improvement of existing reading culture programs, and the types and directions of reading culture programs they would like to see in the future. To this end, a survey was conducted among users of public libraries in the Busan area and the results were analyzed. The survey was conducted online and offline, with 609 respondents. Based on the results of this study, the following implications can be drawn: First, the definition of reading activities is expanding beyond traditional paper books to various digital media, and it is necessary to reflect this change in future program development. Second, as lack of time and lack of information were identified as the main reasons for non-participation in reading activities, libraries and related organizations should offer programs at more flexible times and expand participation opportunities through effective promotion strategies. Third, the continuity and diversity of library reading culture programs should be strengthened, and fourth, they should be differentiated in terms of topics, time, size, and type by age group. Finally, programs should be improved through continuous user surveys. The results of this study can be used as a basis for improving and developing library reading culture programs in the future.

The purpose of this study is to analyze undergraduate nursing students' electronic document use and reading behavior. To do this, a survey questionnaire was collected from 509 respondents who experienced reading behavior for the last semester. The results of this study show that nursing students' preference of electronic documents is higher than that of printed documents in general. They also prefer electronic documents to printed documents when they want to keep documents. Of respondents, about 94% or higher spent 30mins or more to find information and the main source to find information is 'Naver' search engine as the highest information source, and the place to access information is 'Home' as their highest information access location. In particular, the preference of the document 'on the move' is electronic documents and the main reason includes convenience and easiness to access and move the documents. The findings of this study expect to facilitate the understanding of undergraduate nursing students electronic document use and reading behavior so that it can be used to design and develop medical digital library services and tools more effectively and efficiently in medical area in the future. Furthermore, it expects to provide useful data in promoting user services in digital library in a whole.

CD-ROM(Compact Disk-Read Only Memory) is very attractive storage media because it has much storage space but is small size and portable. Optical pickup, one of the most important parts for reading data on a CD-ROM, is not produced tuned up. For the use of goods, we must tune up the optical pickup by adjusting the screw for adjustment. First, we developed analog servo system for optical pickup tuners. For eliminating some problems in analog servo system, this paper designed the modeling of digital servo system for optical pickup tuner. Though the characteristics of optical pickup are changed, the digital servo system for optical pickup tuner can easily apply to all pickup, and can reduce the measurement error among the optical pickup tuners. For the purpose of confirming the designed digital servo system, we produced data that specify the disk vibration and the disk eccentricity, and simulated servo system with MATLAB.
