OneNAND flash is a high-performance hybrid flash memory that combines the advantages of both NAND flash and NOR flash. OneNAND flash has not only all virtues of NAND flash but also greatly enhanced read performance which is considered as a downside of NAND flash. As a result, it is widely used in mobile applications such as mobile phones, digital cameras, PMP, and portable game players. However, most of the general purpose operating systems, such as Linux, can not exploit the read performance of OneNAND flash because of the restrictions imposed by their virtual memory system and block I/O architecture. In order to solve that problem, we suggest a new approach called virtual I/O segment. By using virtual I/O segment, the superior read performance of OneNAND flash can be exploited without modifying the existing block I/O architecture and MTD subsystem. Experiments by implementations show that this approach can reduce read latency of OneNAND flash as much as 54%.

In this paper, I proposed the general children's games and showed the design and implementation of children's games which are non-violent, emotionally helpful and good for the development of intelligence. I designed the user interface of the game for children, proposed relevant algorithms, and showed resultant screens of the game. Most of contemporary games are violent to children. To solve such problems, I designed and implemented the game which is not violent but educative and child-friendly. These days, entertainment games or Internet online games have been developed highly biased to children's interest and amusement rather than children's intellectual development. Usually, disabled children are inferior to normal children in movement of their hands and bodies. Therefore, it is hard for them to follow speedy games. This paper shows that the proposed intellectual development of the game can help disabled children not to be violent and to be more intelligent. That was proved by the results through the question investigation. According to the survey, disabled children's any violent actions were not reported after they played this game. Also, this game helped their intellectual development in accordance with the results of this study.

With the rapid development of information technologies, various types of game devices have been created. Moreover, the game contents are once created, they can be easily reused on several other devies without depending on their platform or media, which phenomena is so called as one source multi use (OSMU). Especially young gamers are good at not only playing the famous computer games but also good at using and utilizing the brand new and the latest mobile devices, they might be the major consumers in the area of mobile games in the near future. This paper discusses and proposes several points to be considered when a conventional computer game to be transformed into a mobile game. Since the points suggested are very useful when the conventional game is to be ported to the mobile devices of inferior performance, it is expected that more profits could be achieved in the market of mobile game with less investment and effort.

This study was to investigate utilization status of internet, health/nutrition websites among children, and to assess the needs for developing nutrition websites and education programs for children. The survey questionnaire was administered to 5-6th grade students (n=434) at two elementary schools. About 32% used the internet every day while 19.5% used it whenever they needed, showing significant differences in internet usage by gender (p<0.01). Although the subjects used the internet frequently, those who used health/nutrition websites were 23.3%. The purpose of using these sites were mainly 'to obtain health/nutrition information' (55%), 'to get information regarding weight control' (17%). Fifty-six percent of the users were satisfied with the nutrition websites, but only 30% said that they were helpful. The preferred topics in developing nutrition websites were assessment of obesity, exercise methods, weight control methods, nutrition information (e.g., diet for stature growth), dietary assessment and food hygiene. Girls showed more interest in these topics than boys (p<0.05). For school nutrition education, girls showed more interest than boys in topics for cooking snacks (p<0.001) and selecting snacks (p<0.05). In nutrition websites, subjects wanted to have information and game/quiz, as well as getting information using Flash animation. The favorite colors for screen and text were slightly different by gender (p<0.01). In school nutrition education, 89.5% of subjects liked to have activities (e.g., cooking, exercise, game). They also liked materials using computers, video and internet than printed materials. If nutrition education was done at schools, subjects wanted to receive 5.7 times of education per semester on average (mean length: 42.6 min/session). This study suggests that nutrition websites and education programs for children should include the topics such as assessment of obesity or diet, weight control and special information (e.g., diet for growth) as well as general information. In designing nutrition websites and programs, methods including game, quiz, Flash animation and activities (cooking, exercise) could be appropriately used to induce the interest and involvement of children.

As DMB, 3D game, Internet and movie is serviced for the recent mobile devices, high resolution display devices beyond VGA become used. Implementation of real-time moving pictures of 30렌 by software programming is difficult because the performance of mobile processors is not so high. The full frame moving picture can be supported by using specific hardware. In this paper, an OLED controller that is consists of flash memory controller and OLED interface is proposed for real-time moving picture on mobile displays. The proposed OLED controller is implemented in FPGA and the performance is evaluated.
