The posters are the tools to communicate authors' idea with others by visual image and a little word. Every discipline has its own sign with specific meaning shared by the members of the discipline. Chemists and students learning chemistry, therefore, will communicate with each other by specific chemical signs (codes). The Korean Chemical Society has held the feast of drawing chemistry posters by students nationwide since 2004. In 2004 and 2005, more than three thousands of posters were submitted, and about one hundred and fifty posters were selected as the prize winners. The award was divided by the grade levels of elementary, middle, and high school. This study explores the codes of chemistry used in students' posters. With the analysis of the visual elements and the verbal elements of posters, 7 chemical codes were found such as the liquid, the experiment apparatus, the graduations, the chemical language, scientists, the earth and environment, and things around us. In addition, the differences were investigated on the grade levels, on awarded or non-awarded poster, and on the years. Educational implications of these findings are discussed.

Teaching programming skills is not only required for computer related departments but through the area of engineering and natural science. Moreover recently teaching programming skill is emphasized in software education for primary schools and secondary schools. Since programming ability is considered an essencial element of national competitiveness, we need programming learning system which alleviates the difficulty. We implemented Blockly webc Programming Convergent Learning System which is based on the graphic tools called Blockly by Google. Inside system problem sets for the programming beginners are embedded in the system. These problem sets are gone under more than 20 years verification and these problem sets may be used to help beginning programmers escape novice coder in short time. Blockly webc Programming Convergent Learning System together with already developed Simple Visual Language2 Programming Learning System is expected to play an important role as a programming learning system for the beginners.

In this paper planed Secret Single Message Service using MVLS(Multipurpose Visual Language System) for conceal contents to other persons that based on national institutions and private organizations report. This system is not persue to important contents like national or company's secret, but merely just decode to general and conceal SMS that using peoples at real life. This system is have an advantage that encoding to message like between lover's conversations or dislike contents to view the other persons, only can see own users that is to keep private life. Also, this system offers convenience to users that using general SMS service and only activate On-Off function for secret mode to user's needs.

Recently, various services through the Internet are gradually increased and developed. The traditional way of examination has been replacing by the online test as well. The most representative is the IBT TOEFL by the ETS in the US. Besides this, a lot of online tests and some related discussions are very fierce to carry out due to the continuous increase of the number of exam candidates. Taking account of the economic issues compared to the previous test, this online method has a lot of strengths. This paper aims to build an online test system based on the 3- tier browser-server architecture, which is different from the commonly used 2-tier based system. This system was achieved using the Visual Studio.Net 2005 and SQL Server 2000 as development tools, and based on the ASP.NET 2.0 platform, using the ADO.NET and C# language.

This study goes into the field of CosPlay that takes place in Korea, and directly observes the people who engage in CosPlays. Based on in-depth interviews, this research identified the reasons why the CosPlay aficionados participate in this practice and their cultural preferences. Ethnography methodology was used to understand the behavior of the cultural entities of CosPlays. Moreover, this research attempted to understand their daily formalities through their own perspective and language instead of superficial language. In general, CosPlay form that they manifest is classified into two main categories: those who enjoy posing by becoming their favorite characters and those like to wear the clothes of their favorite characters and go up on the stage to perform an act of animation or game where the applicable character appears. Some of these groups are: 1) 'Bishojo CosPlay' that CosPlays mostly Bishojo cartoon characters and wants to just stand out, 2) 'Aekyo' group that CosPlays merely for the sake of the enjoyment of wearing costumes instead of having the mania-like characteristics, 3) 'CosPlayer Group' who enjoy doing organized team CosPlay in order to present a performance, 4) 'J-Rock CosPlay' group that CosPlay Japanese visual rock groups and prepare to be among a professional CosPlay team, and 5) 'People related to Cospre.com' who try to make CosPlay rooted in as one of new cultures.

In this paper, we present the HVIS (Hybrid Video Information System) which bolsters up meaning retrieval of all the various users by integrating feature-based retrieval and annotation-based retrieval of unformatted formed and massive video data. HVIS divides a set of video into video document, sequence, scene and object to model the metadata and suggests the Two layered Hybrid Object-oriented Metadata Model(THOMM) which is composed of raw-data layer for physical video stream, metadata layer to support annotation-based retrieval, content-based retrieval, and similarity retrieval. Grounded on this model, we presents the video query language which make the annotation-based query, content-based query and similar query possible and Video Query Processor to process the query and query processing algorithm. Specially, We present the similarity expression to appear degree of similarity which considers interesting of user. The proposed system is implemented with Visual C++, ActiveX and ORACLE.

Objectives: Children with attention-deficit/hyperactivity disorder (ADHD) tend to be noisy and violate rules with their disruptive behaviors, resulting in greater difficulties with off-task behaviors and being at risk for social refusal. The visual activity schedule (VAS) intervention program is a frequently used method to teach multiple skills involving on-task, use of schedules, transition behaviors, social initiation, independent play skills, classroom skills, and academic skills. The current systematic review aimed to examine the efficacy of using VAS intervention in reducing problem behaviors in children with ADHD between 5 and 12 years of age. Methods: Systematic searches were conducted using two electronic databases (PubMed and Scopus) to identify relevant studies published in English between 2010 and 2020. Four studies met the inclusion criteria: two studies examined the effect of schedule-based tasks and the use of an iPad on classroom skills, while the other two examined randomized clinical trials (RCTs) of psychosocial treatment for ADHD inattentive type and a cross-sectional study examined the impact of the group size on task behavior and work productivity in children with ADHD. Results: The findings indicate that the interventions used in all four studies could lead to increased satisfaction among participants and parents, as well as a reduction in problem behavior. In terms of the research indicators, the RCT had low quality, while the others were of high quality. Conclusion: A larger number of studies and the ADHD clinical population would help to increase the generalizability of future reviews of treatments in this context.

In this paper, we propose TV caption-based KSL(Korean Sign Language) generation system. Through TV caption decoder, this caption signal is transmitted to PC. Next, caption signal is segmented into meaning units by morphological analyzer in considering specific characteristics of Korean sign language. Finally, 3D KSL generation system represents the transformed morphological information by 3D visual graphics. Specifically, we propose a morphological analyzer with many pre-processing techniques for real-time capability. Our developed system is applied to real TV caption program. Through usage of the deaf, we conclude that our system is sufficiently usable compared to conventional TV caption program.
