컴퓨터 게임 개발에 있어서 가장 중요한 요소 중의 하나는 창의적인 아이디어이다. 컴퓨터 게임 개발의 프로세스의 1단계 작업과정에서 핵심은 창의적인 아이디어를 발상하는 것이다. 이러한 과정을 위해 선행연구 개발된 웹 기반 창의적 발상시스템(Creative Group Thinking System:이하 CGTS))을 통하여 게임 개발에 적용하여 활용하고자 한다. 따라서 본 연구는 게임디자인 작업부분의 아이디어발상 작업을 웹 환경에서 프로그램화하여 창의력을 높이고 작업시간을 단축하며, 완성도를 높이고자 한다.

This paper describes the Tezpur University dataset of online handwritten Assamese characters. The online data acquisition process involves the capturing of data as the text is written on a digitizer with an electronic pen. A sensor picks up the pen-tip movements, as well as pen-up/pen-down switching. The dataset contains 8,235 isolated online handwritten Assamese characters. Preliminary results on the classification of online handwritten Assamese characters using the above dataset are presented in this paper. The use of the support vector machine classifier and the classification accuracy for three different feature vectors are explored in our research.

This study describes the successful establishment of a cryopreservation protocol for Citrus limon cultivars: 'Frost Eureka limon' and 'Cook Eureka limon', using a droplet-vitrification method. The shoot tips that were excised from in vitro grown seedlings of the two cultivars were preserved in liquid nitrogen (LN) and successfully regenerated into whole plants. Excised shoot tips were pre-cultured for 1 or 2 days in 0.3 M and 0.5 M sucrose solutions at $25^{\circ}C$ and incubated in a loading solution (LS) composed of 17.5% glycerol + 17.5% sucrose in Murashige and Skoog (MS) medium for 40 min at $25^{\circ}C$. Prior to direct immersion in LN for 1 h, the shoot tips were dehydrated with plant vitrification solution 2 (PVS2) at $0^{\circ}C$ or PVS3 at $25^{\circ}C$. The frozen shoot tips were re-warmed and unloaded with 1.2 M sucrose in $\text\tiny{^1/_2}$ MS for 30 min at $25^{\circ}C$. Shoot tips were post-cultured overnight on survival medium and then micrografted onto 'trifoliate orange' (Poncirus trifoliate (L.) Raf. seedling rootstocks for recovery and to produce whole plants. The highest regrowth rates were 53.5% and 50.3% for cryopreserved shoot tips of 'Frost Eureka limon' and 'Cook Eureka limon', respectively, when pre-cultured in 0.3 M and 0.5 M sucrose concentrations in a sequencing manner, with LS and treated with PVS2 for 60 min at $0^{\circ}C$. We also investigated whether the ammonium ion concentration on post-culture medium affected the viability of the cryopreserved Citrus shoot tips. The viability of cooled samples, following culturing on woody plant media (WPM) containing $\text\tiny{^1/_4}$ ammonium nitrate overnight before micrografting, was the highest (70.3%) in 'Frost Eureka limon'. The study described here is a cost-effective and safe method to conserve Citrus fruit cultivars, for the improvement and large-scale multiplication of fruit plants and for breeding disease resistance.

Understanding the adhesion behavior and characteristics of toner film is required to achieve image and text printing with high quality resolution. Toner can be considered as a thin film coating on a media such as paper or polymer film. Quantitative measurement of adhesion characteristics of the thin film is important to assess the reliability of the system. In this work the main objective was to investigate the adhesion characteristic between the toner and the media by ramp loading scratch test method. The scratch test may be used to obtain quantitative information about the adhesion of the film to the substrate. In the scratch test a diamond tip was used to scratch the surface of the toner film under an increasing normal load until the toner detached or fractured. The critical load (LC) was obtained from the experimental results. Also, the relationship between the critical load and the adhesive strength of the interface between the substrate and the toner was obtained by measuring the normal and tangential forces during the scratch test. Finally, theoretical analysis of the toner scratch characteristics was performed based on Benjamin and Weaver theory, Plowing model, and Laugier model.

This study aims to analyze the objectives of environmental education in Environmental Impact Assessment (EIA) and the Education for Sustainable Development(ESD) factors used EIA in 'ecology and environment' textbook, and finally to analyze the situation and contents level of EIA domain in textbook to explore the possibility of the positive availability of EIA domain in high school for realization of effective ESD. To analyze the objectives of environmental education in EIA and ESD factors used EIA, researchers used the text, the activity and the teaching tip in three kinds of 'ecology and environment' textbook by the 7th curricula as the object of analysis. Framework to analyze the objectives of environmental education in EIA is the category of environmental education objectives of UNESCO presented according to 'Tbilisi Intergovernmental Conference on Environmental Education' and framework to analyze ESD factors used EIA is developed on the basis of the theory about EIA and ESD factors updated in this study. In conclusion, it proves that the EIA domain through the activity is effective for realization of ESD. According to the analysis of the study, it is proposed that the follow-up studies on the improvement of EIA domain in textbook in both quality and quantity as well as 'the teaching & learning methods and various development of teaching materials, etc: based on the emphasis on the activity are needed to progress steadily for realization of effective ESD in high school in the future.
