본 논문에서는 아동 자신의 경계를 스스로 인식할 수 있는 내용을 담은 영상 콘텐츠를 제시하고 능동적인 학습을 위한 터치 방식의 콘텐츠를 구현한다. 영상은 총 4개의 모듈로 구성되어 있으며 각 스토리는 내용 전개, 경계 존중 개념 학습, 학습 내용 평가로 진행된다. 경계 존중개념은 성폭력이 일어나는 상황 역시 경계를 넘나드는 행위로 보여 주어 성폭력 문제가 아동 안전의 연장선에 있다는 인식을 심어주는 것을 목표로 하고 있다. 그리고 학습 내용 평가는 터치 게임을 통해 게임에 성공하면 상을 받는 것으로 사용자에게 학습 성취도를 높여준다.

New teaching and studying methods using educational contents are gradually widespread with the advancement of information and communication technology. As educational contents, in this paper, we design and implement linguistic contents for studying essential expressions applied to various situations of real life. In detail, the linguistic contents are run on web environments, and have suitable animations for learning essential expressions based on several foreign languages in contextual dialogues. Also, useful functions are included in contents to reinforce what users have learned.

지식정보화의 사회적 발전에 따라 IT기술도 장소와 공간에 제약 받지 않는 이동성, 휴대성이 강조되고 있다. 이는 유비쿼터스 사회로의 급격한 진입이라는 시대적 상황과 맞물려 유비쿼터스 컴퓨팅 환경에 적합한 컴퓨팅 디바이스의 등장이 요구되고 있다. 본 논문에서는 다양한 포터블기기(PMP, UMPC, MP3, 게임기)들의 기능과 콘텐츠를 조사, 분석하여 차세대 포터블 멀티미디어 시스템에서 요구되는 기능을 도출하였으며 또한 이를 기반으로 모듈화 된 포터블 멀티미디어 시스템의 구조를 설계했다. 본 연구의 결과는 점차 성숙해가고 있는 포터블 멀티미디어 시스템 산업의 하드웨어적 표준을 제시함으로써 효율적인 개발 방안을 모색할 수 있을 것으로 기대된다.

소프트웨어 제작자들이 불법복제로부터 그들의 제품을 보호하기 위해 노력하는 것처럼 콘텐츠 제작자들도 사용자간 불법 콘텐츠 공유를 규제하기 위해 노력하고 있다. 본 연구는 이러한 시도가 과연 저작권자의 권익을 보호하고 그들의 수익을 극대화할 수 있는 근본적인 해결책이 될 수 있을 것인지에 대하여 경제적 측면에서 논의한다. 이를 위해 불법 콘텐츠 공유에 대한 규제가 제작자의 수익에 미치는 효과를 파악하기 위한 분석적 모형을 개발하고 규제와 비 규제하에서 콘텐츠 제작자의 수익극대화를 위한 최적 조건을 제시한다. 분석결과, 정품 콘텐츠와 불법 복제 콘텐츠간의 충분한 차별화가 어려운 경우에는 불법 복제의 규제가 긍정적인 효과를 줄 수 있으나 정품 콘텐츠와 불법 복제 콘텐츠 사이에 충분한 차별화가 가능한 경우에는 오히려 규제가 없는 경우에 저작권자의 수익이 극대화되는 것으로 나타났다.

This study aimed to identify the effects of contents, to find out the development approaches of promotion and contribute to increase the expectation on medical institutions and wills to use and improve the customer satisfaction on homepages of such medical institutions by analysis on the contents of hospital homepage. This research performed the frequency analysis, cross analysis, t-test correlation analysis, and multiple regression analysis and came to the conclusion. In accordance with the research results, since the university hospital homepages had more contents than the homepage of general hospitals and national and public hospitals, the university hospital homepage provided sufficient information to visitors and tried to satisfy the customers and activate the hospital promotion using the homepage contents. On the contrary, the homepage of general hospitals and national and public hospitals had insufficient contents and unique and differentiated contents were not sufficiently provided. On the basis of the results of this study, further study on the approaches to improve the contents of homepage of general hospitals and national and public hospitals will be of great help to activate the hospital promotion by increasing the average number of visitors and page views. Furthermore, it is required to make every endeavor for systematic management and operation and research on promotion using the homepage contents.

This study reflects the demand of content elements related to "Human Reproduction" in elementary school science curriculum, and verifies its effects by developing and applying sex education contents available to elementary science class. The developed contents is composed of three sections in reference to the contents guideline for teachers. The contents include anatomical knowledge related to human reproduction and reflect social and cultural context of sex ethics. The first section: "How was I born?", second section: "Amazing changes in my body" and third section: "Healthy body, healthy mind." In the result of analysis of changes in sex knowledge and attitude after applying the contents, it showed statistically significant differences between experimental and comparative class. Thus, the developed contents made positive influence on improvement in elementary students' knowledge and attitude of human reproduction. However, it showed little difference in the effects of sex education contents by the grade and gender. In conclusion, if the sex education contents developed through this study is actively applied, it is expected to provide the elementary students with knowledge of the anatomic difference between male and female, its social and cultural understanding and responsibility for sex ethics. In addition, it is considered to be used as effective education programs and materials in elementary school science curriculum.

This study was conducted to determine the extent of drought resistance based on physiological responses of Calystegia soldanella under water deficit. In order to investigate the changes of plant growth, stomatal density, photosynthesis, chlorophyll fluorescence, the contents of chlorophyll and carotenoid, osmolality, total ion contents, the contents of carbohydrate and proline, C. soldanella was grown under well watered and drought stressed conditions for 12 days. In this study, water-deficit resulted in remarkable growth inhibition of C. soldanella. The effect of water-deficit on plant growth was associated with low osmotic potential of soil. On day 12 after drought treatment, dry weight, relative water contents, number and area of leaves and stem length were lower than those of control. The stomatal conductance and net photosynthetic rate were significantly reduced in water stressed plant to regulate inner water contents and $CO_2$ exchange through the stomatal pore. Chlorophyll fluorescence and chlorophyll contents were not different in comparison with the control, indicating that the efficiency of photosystem II was not affected by drought stress. This results could be explained that water-deficit in C. soldanella limits the photosynthetic rate and reduces the plant's ability to convert energy to biomass. A significant increase in total ion contents and osmolality was observed on day 7 and day 12. Accumulation of proline in leaves is associated with the osmotic adjustment in C. soldanella to soil water-deficit. Consequently, this increase in osmolality in water stressed plant can be a result in the increase of ion contents and proline.

Varietal and annual variations in the contents of ${\beta}$-glucan fractions per weight grain samples were examined in sixteen covered and eighteen naked barley and five oat cultivars developed in Korea. Also, the effect of pearling on ${\beta}$-glucan content was investigated. Average contents of total, soluble and insoluble ${\beta}$-glucan fractions were 5.25, 3.72, and 1.53%, respectively, in covered barley, and 5.86, 3.51, and 2.35%, respectively, in naked barley. Soluble ${\beta}$-glucan content was higher in covered barley, though total ${\beta}$-glucan content higher in naked barley. The total and insoluble ${\beta}$-glucan contents were higher in pearled grains. Total ${\beta}$-glucan content was higher in waxy barley than in non-waxy barley. Duwonchapssalbori, a two-rowed and waxy naked barley cultivar, was highest in total, soluble and insoluble ${\beta}$-glucan contents. Highly significant positive correlations were observed between total ${\beta}$-glucan and soluble ${\beta}$-glucan contents both in covered and naked barley. There were significant annual variations in total ${\beta}$-glucan content in barley. Average contents of total, soluble and insoluble ${\beta}$-glucans of oat cultivars were 4.33, 3.44, and 0.89%, respectively. Contents of all fractions of ${\beta}$-glucans were higher in barley than in oat. These results would be useful for the breeding of high ${\beta}$-glucan variety and also for the use barley and oat as valueadded food ingredients.
