This study was designed to examine children's comprehension monitoring ability. Specifically the purpose of this study was to investigate (1) children's monitoring standards preference according to monitoring ability, and (2) the relationships between comprehension monitoring and working memory capacity. The subjects were 60 children, 30 each in 2nd and 4th grades. To measure comprehension monitoring ability, 7 stories including erroneous sentences were used. Working memory capacity was measured by the Reading Span Test (Lee, 1995). Results showed that (1) the high and low monitoring children were not different in monitoring standard preference, and (2) comprehension monitoring ability was significantly and positively related to working memory capacity.

The purpose of this study is to investigate how $3^{rd}$ and $4^{th}$ grade elementary students view about 'Science story', which is recently inserted in the new version of science text books. For the study, four hundred $4^{th}$ graders at four schools were considered in the area of Cheonan city, Chungnam province. The degree of student's preference, preferable science topics from the 'Science story', the reason for their preference, and their attitudes toward general science were examined. The study was initiated after student's reading of the 'Science story' (Advanced science, Science in the life, Science in the history, and Future science directions). The student attitudes toward general science were examined using questionnaire survey prior to others. The results of the study are summarized: First, the students who have more interests and affirmative attitudes about science subjects with high scores are more favored about 'Science story'. Second, generally the students prefer reading topics in the order of 1) Science in the life, 2) Advanced science, 3) Science in the history, and 4) Future science directions. However the order was flexible depending on student's gender, preference, and attitudes. Third, the student's interests about 'Science story' was mostly raised from the new scientific topics in the book. And it was also raised partly from their personal interests and usefulness for science learning. Based on the results of our study, we included some suggestions for the improved 'Science story' and their utilizations.

Television market is rapidly changing into HDTV according to increase in the programs transmitted in HD. However, there is no guideline of Korean typography which is suitable for HD display. Here we provide a guideline on Korean font style, its size and transparency to acquire high readability on HD screen. The readability was assessed with two different criteria: reading speed as an objective index and preference ranking as a subjective index. In the results, the participants tend to prefer and read faster slim fonts on HD display when compared to the bold type commonly used on 3D display To the font size, smaller one was preferred on HDTV than that displayed on SDTV. To the transparency, users revealed strong preference on 40% transparency although it did not affect the reading speed when the contrast between text and background was fixed on 40%. But clearly, preference on 40% transparency.

This study analyzed the contents of Goodreads review data, which is a social cataloging service with the participation of book users around the world, to identify the preference factors that affect book users' book recommendations in the library information service environment. To understand user preferences from a more detailed point of view, sub-datasets for each rating group, each book, and each user were constructed in the sample selection process. Stratified sampling was also performed based on the result of topic modeling of review text data to include various topics. As a result, a total of 90 preference factors belonging to 7 categories('Content', 'Character', 'Writing', 'Reading', 'Author', 'Story', 'Form') were identified. Also, the general preference factors revealed according to the ratings, as well as the patterns of preference factors revealed in books and users with clear likes and dislikes were identified. The results of this study are expected to contribute to more sophisticated recommendations in future recommendation systems by identifying specific aspects of user preference factors.

The purpose of the study is to investigate the characteristics of the elderly housing preference and spatial usage to plan floor space of the elderly housing by the respondents of the ages 50 to 79. Based on the result of the study, it is suggested that the elderly housing should be located in regards to social environmental factors rather than natural environmental ones. There are differences in preference for the space planning of housing units such as the number of rooms and bathrooms, and floor space depending on income level, so the housing should be differently planned to accept the difference of preference. On the other hand, there is not notable difference in furniture preference for each space. In the characteristics of spatial usage according to behaviors, high-income respondents demonstrate the characteristics of spatial usage in accordance with a western lifestyle. Thus, behaviors such as sleeping, watching TV, resting, reading, conversation, and receiving guests, occur using such things as beds, sofas, and dinning tables. On the other hand low-income respondents show a mixed western and traditional lifestyle. Thus many behaviors are done on the floor of bedroom and livingroom in addition to using furniture such as a sofa and chairs. Therefore, the way of spatial usage has to be reflected in the floor space planning. At least floor space of the provided rooms should be planned to accommodate the behavior of the elderly even though all of the rooms preferred can not be provided.

This study performs the subjective evaluations of LED illumination conditions according to three types of color temperatures (7,000[K], 5,000[K], 3,000[K]) after employing LED illumination system in the classroom, Since the objective of this study is to develop an artificial lighting conditions like day light comfortable to students in the classroom, the learning effect based on three types of LED illumination conditions are analyzed. Three factors (learning intention, learning environment, learning motivation) are extracted by ANOVA and there are preference differences of LED illumination conditions between learning intention and learning environment factors. Especially, preference differences of LED illumination conditions are existed about calculation, reading and fatigue reduction. The test results of this study can be applied to obtaining high achievement of learning based on the lighting conditions.

Purpose: The aim of this study was to determine a suitable type and size of Hangul fonts for printed materials in the presbyopic age. Methods: Based on the most common Hangul fonts used today, three types of fonts were used Hamchrombatang, Sinmoonmyungjo and Sinmyungjo at small font sizes in the range 9-11 point (pt). Subjects were 101 volunteers aged 41 through 85 years. Near visual acuity (VA) was corrected to read VA 0.5 at 40 cm after distance correction. The subjects were asked to read words containing 88 characters in 10 pt after a question about preference. Readability was assessed by reading rate that was calculated as the number of words read correctly in one minute (words per minute, wpm). Results: The most preferred font type was Simmyungjo at small font sizes. Although preferred font sizes were different in each font type, Sinmyungjo was generally preferred at 10 pt more than other fonts. Hamchrombatang and Sinmyungjo were read significantly faster than Sinmoonmyungjo. There was a weak negative relationship between readability and age in Sinmyungjo. In comparing between the top 10% and the bottom 10% group sorted by reading rate, the top group showed lower average age and addition than the bottom group, however there were no significant differences in reading rate among the fonts. Conclusions: Although increasing age tends to be low in readability for Sinmyungjo, in the light of preferred font and readability, it is recommended to use a 10 pt Sinmyungjo font in printed materials for the presbyopic age.
