미리 읽기(readahead) 설계는 파일 시스템 성능에 큰 영향을 미치는 요소 중 하나이다 기존 리눅스 커널 2.6.7 버전의 미리 읽기는 임의적 파일 접근 시에 읽는 크기가 클수록 사용되지 않는 페이지들의 할당에 시간을 낭비하게 되어 전체적인 성능 저하가 일어난다. 본 논문에서는 이러한 문제를 해결하기 위해 요청되는 읽기 크기에 따라 미리 읽기 크기를 조정하는 방법을 제안하며 제안된 방법으로 리눅스 커널을 수정하여 임의적 파일 접근 시에 성능 향상이 일어남을 실험을 통해 보이고자 한다.

Teachers unfold a series of timeless mathematical symbols such as 5+2=7 in time by verbalizing the symbols in classrooms. A number sentence 5+2=7 is read in Korean as '5 더하기 2는(five plus two) 7과(seven) 같다(equals). Unlike in English, 5+2 and 7 are read first before the equal sign in Korean. This sequence of reading in Korean conflicts with the conventional linguistic sequence of writing from left to right. Ways of resolving the discrepancy between reading and writing sequences can make a difference students' understanding of the equal sign. Students would be in danger of perceiving the equal sign as an operational symbol, if a teacher resolves the discrepancy by subordinating reading sequence to linguistic convention of writing. This way of resolving results in the undesired phenomenon of changing the reading expressions in Korean elementary math textbook which represent relational notion of the equal sign into other reading expressions that represent operational notion of it. For understanding of relational notion of the equal sign, the discrepancy should be resolved by changing writing sequence in accordance with reading sequence. In addition, teaching of verbalizing the equal sign should be integrated with teaching of verbalizing inequality signs.

본 연구는 결속장치(cohesive devices)가 과학텍스트의 읽기 속도와 내용 이해에 끼치는 영향에 대해 연구하였다. 연구의 목적을 위한 실험을 통해서 먼저, 텍스트의 문단별 읽기 시간을 측정하여 온라인 처리 과정을 검토하였고, 둘째, 회상과 재인 검사를 실시하여 오프라인 상태에서의 이해도를 조사하였다. 이 연구의 재료로 사용된 텍스트는 번개 생성과정에 대한 과학텍스트로서, 반복, 지시사, 정박(anchoring), 인과적 접속사 등의 결속장치를 이용하여 응집성(coherence)의 강도를 높고, 낮게 조작하였다. 실험 결과, 결속장치가 길속장치의 종류와 지엽적 응집성의 강도에 따라 과학텍스트 읽기와 이해에 선택적으로 영향을 끼친다는 것을 발견하였다. 첫째, 인과적 접속사는 읽기 시간에는 영향을 주지 않는 반면, 이해를 촉진했는데, 이 긍정적 효과는 과제의 종류에 따라 다르게 나타났다. 즉, 회상 검사 결과에서는 인과적 접속사가 쓰인 모든 문단에서 유의한 차이가 나타났으나, 재인 검사에서는 유의한 차이가 부분적으로만 나타났다. 둘째, 반복 결속장치는 다른 결속장치와 같이 발생할 경우에만 읽기 시간과 이해를 부분적으로 촉진하는 것으로 나타났다. 셋째. 정박 결속장치의 영향은 읽기와 이해 두 처리 과정에 모두 선택적으로 영향을 준 것으로 나타났다. 인과적 접속사와 함께 쓰인 문단의 경우에는 회상 검사에서만, 반복 결속장치가 함께 쓰인 문단에서는 회상, 재인 검사에서 모두 긍정적 영향을 준 것으로 관찰되었다.

In this study we examined the context effects in reading Hangul (Korean alphabets) in normal and low vision, using the two different reading techniques, self-paced reading (Experiment 1) and rapid serial visual presentation (Experiment 2). We compared the reading speed of participants with normal or low vision in sentences vs. randomly ordered words. The results from both experiments showed that the reading speed of participants with low vision slowed significantly relative to those with normal vision. However, the patterns in the size of context effects were different in the two experiments. The context effects were larger in low vision than in normal vision in self-paced reading, but they were smaller in low vision than in normal vision in RSVP. This result indicates that context may make a greater contribution for readers with low vision than for readers with normal vision when sufficient time is allowed to read; in contrary, its contribution is smaller for readers with low vision than for readers with normal vision when there is time limitation for reading.

The purpose of this study is to analyze the meaning of picture book reading experience for 2-year-old children using sensory reading media and to suggest a plan to support language ability through meaningful reading. For this study, 35-month-old boys were selected, and data collection was conducted based on participant observation and field record notes at home and analyzed qualitatively. In this study, for about two months from March 20th to April 30th, 2021, all the time of exploring picture books and playing were recorded and the data were collected. The recording time was about 20 hours, and the collected data and field records were transcribed on 108 pages of A4 paper. The results of the study showed that 2-year-old infants were immersed in exploring new media through the experience of reading picture books using sensory reading media, comparing with similar media, and reading picture books using media. In addition, it was found that the emergence of leading reading that selects and reads books by Hans himself, exploration using reading media, and play linked to picture books in everyday life.This can be seen as a result of suggesting that the picture book reading experience of 2-year-olds using sensory reading media is meaningful to the reading experience of infants.

In this study, Korean older adults (70-75 yrs) were divided into two groups according to the degree of reading exposure, and real-time data were collected through a reading eye movement tracking experiment. Then, overall reading patterns and word frequency ef ects were compared with two groups of older adults and younger adults (20-28 yrs). Furthermore, through the results of the eye movement tracking experiment of older adults with rich reading exposure and older adults with poor reading exposure, we tried to find out whether reading performance af ects not only changes in age but also reading exposure. As a result of the experiment, the older adults with poor reading exposure group generally had a longer fixation time and a shorter saccade than the younger adults group, and the older adults with rich reading exposure group showed the same reading patterns as the younger adults group. The word frequency ef ect was confirmed in all groups, and the fixation time was short in the order of older adults with rich reading exposure group and older adults with poor reading exposure group. In addition, an interaction ef ect was shown in the two elderly groups according to reading exposure, but no interaction could be confirmed in the dif erence between the younger adults group and the older adults with rich reading exposure group. This suggests the possibility that reading performance is not af ected by age itself, but by the reading experience of the elderly.

Two experiments were conducted to examine psychological reality and incremental nature of thematic processing in Korean sentence comprehension. By using two different types of verbs (i.e., transitive and causative verbs), we manipulated necessity of the thematic reanalysis (i.e., consistent vs. inconsistent condition) in the coordinated sentence structures. In Experiment 1, there was no significant difference in the reading times of the verbs between the consistent and the inconsistent condition. However, there was significant differences in question answering times between the two conditions. In Experiment 2 in which we changed a noun phrase of the test sentences into inanimate one, we found significant thematic reanalysis effects in the reading times of the final verbs. Based on these results we discussed the theoretical importance and universality of the thematic processes.

In an attempt to promote reading among middle school students which has been declining sharply, this study suggests new directions for reading education in school libraries. The study examined the following: correlation between students' attitudes toward reading and their reading achievements as revealed in PISA 2009, nationwide survey results on reading, and studies on attitudes and motives for reading. Korean students' reading achievement is very high among the OECD countries but their reading attitude is not positive enough. The strong positive relationship between pleasure reading and reading achievement indicates the importance of the provision of ample collections at school libraries as well as library programs fostering independent, free-will reading. Reading programs at school libraries should cater to students' individual characteristics and needs, such as their sex, abilities, affective and cognitive attitudes, experiences, as well as the quantity, the formats, and the time of their reading, etc.

The primary purpose of this study is to analyze the learning activities of "the Reading a Book per Semester" with the goal of finding ways to collaborate with the school library. "the Reading a Book per Semester" is a program that requires students to read during the timetable-designated "Korean" class instead of encouraging students to read outside of class, as has been the case thus far. The program was designed by 3 parts: reading, sharing, and formulating. However, an analysis of 11 Korean textbooks and 22 approaches to the program showed that the model has shifted to . Under this new model, schools could expand each step in the following ways: utilize the school libraries more as the book search space during the selection process; include writing a reading diary in the reading process; and further encourage students to read outside of the classrooms in the formulating step. If these amendments were to be applied, they would strengthen the educational purpose of the school libraries within schools.

최근 빅데이터를 처리하기 위한 고용량의 저장장치의 연구가 활발하게 진행되고 있다. 특히 낸드 플래시 메모리 기반 저장장치인 SSD(Solid State Drive)는 고속 데이터 처리가 가능하기 때문에 다양한 저장 시스템에서 사용되고 있다. 그러나 낸드 플래시 메모리는 읽기 속도가 빠르고 쓰기 속도가 느린 비대칭 구조를 가지고 있어 데이터 쓰기 작업이 진행 중일 때 다른 작업이 대기하게 되어 전체적인 시스템 성능에 영향을 미칠 수 있다. 이에 대해 대부분의 연구에서는 쓰기 성능을 개선하기 위한 버퍼 관리 정책들이 제안되었다. 기술의 발전으로 쓰기 성능은 개선되었지만, 그에 비해 읽기 성능이 저조한 문제가 있다. 본 논문에서는 읽기 성능이 쓰기 성능보다 취약한 점을 분석하고 플래시 메모리 내에 저장장치 속도를 개선하기 위해 앞으로 읽기 요청 가능성이 있는 예상 데이터를 선형회귀 모델을 적용하여 전송 대기 시간 중 미리 읽는 정책을 제안한다.
