Um von der 'kritischen' Situation des Faches DaF rauszukommen, werden viele Versuche untemommen, durch die Verbesserung des Untenichts in der Richtung nach der Entwicklung der kommunikativen $F\"{a}higkeit$ Deutsch als Fremdsprache wieder attraktiv und $konkurrenzf\"{a}hig$ zu machen. Aber leider sieht die Zwischenbilanz nicht so erfolgreich aus. Eine der Ursachen $daf\"{u}r\;l\"{a}sst$ sich mE. darin sehen, dass die $Ans\"{a}tze,\;die\;haupts\"{a}chlich\;f\"{u}r$ den Unterricht von Deutsch als Zweitsprache entwickelt wurden, ohne $gen\"{u}gende$ Berucksichtigung auf die kulturellen und institutionellen Unterschiede zwischen den Lemsituationen im zielsprachigen Land und im Heimatland der Schuler eingesetzt werden. In diesem Kontext $w\"{a}re\;es\;n\"{o}tig$, auf die Unterschiede zwischen DaF und DaZ und ihre Wirkung auf die Lehrstrategien im DaF-Unterricht zuruckzugreifen, Dabei sind auf einige Faktoren besonders zu achten, die DaF-Untenicht vom DaZ-Untenicht unterscheiden: die Mangel an den $M\"{o}glichkeiten$ der authentischen Kommunikation, die $Homogenit\"{a}t\;der\;Sch\"{u}ler$, die Lemkultur in der schlulischen Institution, das Alter, in dem die Sch\"{u}ler$ mit dem Lemen der Zielsprache beginnen. Daraus lassen sich die folgenden unterrichtlichen Konsequenzen ergeben: Die Lehrer sollten sich bemtihen, den $Sch\"{u}lern\;die\;M\"{o}glichkeiten\;f\"{u}r$ die authentischen Kommunikation besorgen, besonders $au{\ss}erhaib$ des Unterrichts, z.B. durch das Chatting- Projekt, $w\"{a}hrend$ im Unterricht mehr $Anl\"{a}sse\;f\"{u}r$ die Reflexion gegeben sollten. Und dabei sollten die unterrichtlichen Vorteile-die gemeinsame Muttersprache und Kultur, das Alter usw. - aktiv benutzt werden. Die meisten Koreaner beginnen $n\"{a}mlich$ mit dem Lernen der zweiten Fremdsprache erst in oder nach der $Pubert\"{a}t$. In diesem Zusammenhang sollte es auch betont werden, dass sich die Autonomie der Lerner durch den Unterricht richtig entwickelt, damit sie $sp\"{a}ter$ ihre Fertigkeiten autonom entwickeln $k\"{o}nnen$.

Purpose of this study is to investigate influence on preference of cohousing (eg. intention to spread and intention to move in cohousing) according to sense of community, especially in housing life by married people residing in Seoul and its outskirts. Research method used for this study was a social survey. Respondents were 214 people by accidential sampling. The collected data were analyzed by SPSS 12.0 program using frequency, mean, average, T-test, one-way Anova, Duncan's Multiple Range test and Chi-square test. Findings of this study were as follows. Most respondents took part in interactive activities with colleagues from the same occupation. They Focused on the issues about health, leisure and hobby. The respondents mainly wanted to have interaction for changing recycling materials and education programs for children and juveniles. Degree of ideal relationships with neighbors, they think, were greeting and chatting as well as communication about issues on child-care, education for children, offense-prevention and safety. Although respondents were interested in community life and in interaction with their neighbors, they did not build up communal society due to lack of a sense of belonging in their living areas. While respondents showed positive response about preference of cohousing, there were difference between intention to spread of cohousing and intention to move in cohousing. As a result of this study, the stronger sense of community in housing life meant the more interests in thoughts to spread and to move in cohousing. Therefore, in order to increase sense of community in cohousing, the plan of various communication programs that enables frequent interaction among neighbors is needed. Also, in order to spread cohousing in Korea, promotion of cohousing community and cognitions about it are the most needed.

Recently, the demands for real-time service and multimedia data are rapidly increasing. There are significant redundancies between header fields both within the same packet header and in consecutive packets belonging to the same packet stream. And there are many overheads in using the current UDP/IP protocol. Header compression is considered to enhance the transmission efficiency for the payload of small size. By sending the static field information only once initially and by utilizing dependencies and predictability for other fields, the header size can be significantly reduced for most packets. This work describes an implementation for header compression of the headers of IP/UDP protocols to reduce the overhead on Ethernet network. Typical UDP/IP Header packets can be compressed down to 7 bytes and the header compression system is designed and implemented in Linux environment. Using the Header compression system designed between a server and clients provides have the advantage of effective data throughput in network. Since the minimum packet size in Ethernet is 64 bytes, the amount of reduction by header compression in practical chatting environment was 6.6 bytes.

Purpose: The purpose of the study is to develop and to evaluate a internet-based social support program for the mothers of congenitally abnormal children. The theoretical basis of the study is the moderating effect model of social support theory (Cobb, 1976). Methods: In first phase, an internet support program was developed according to the practical web development stages proposed by Boling and Frick (2002). In the second phase, the internet support program was provided and evaluated to 18 mothers who reared congenitally abnormal children from March to May 2008. Results: In the first stage, demands of the program were collected from interviews of eighteen mothers of congenitally abnormal children of ages one to three. At the same time, literature review and validity of the contents were also examined. In the second stage, the correspondence of the program contents to the social support needed was also examined. In the third and fourth stages, prototype of the social program was prepared in documents and that of computer program was prepared. In the final stage, an internet-based web site was constructed. The social support provided by the web site were composed of informational support, emotional support and appraisal support including bulletin board system and chatting service. After program development, pre-tests and post-test were performed to investigate the effect of the program on maternal confidence and mood. Data were analyzed using Wilcoxon signed rank test. The analysis showed that maternal confidence of post-test was improved than that of pre-test with statistically meaningful figure (Z=-2.54, p<.05). The positive mood of post-test was also improved than that of pre-test and the result was statistically supported (Z=-2.20, p<.05). Conclusion: It is suggestive that the internet based social support programs is accessible and appropriate service to congenitally abnormal children's mother. It is necessary to develop and use the internet based social support programs in public health system.

As information technology has been developed in a rapid way, a lot of users get to be familiar with social media. Accordingly, the possibility of social media for educational use has increased. From the view point of learning, social media help learners make communities of practice that can lead to collective intelligence. In this study, two different types of social media, synchronous and asynchronous, were compared in terms of usage patterns in the e-learning settings of college level. Content analysis has figured out four factors: learning content, tasks and assignments, emotional communications, and chatting. There found to be a statistical differences in the postings in all of the factors except tasks and assignments. In the qualitative interviews, the participants told various usage patterns of synchronous and asynchronous social media. In sum, the learners generally preferred synchronous social media. Rather, asynchronous social media were mainly used for deep thinking and summarizing. Last, suggestions were made to improve educational environments for the learners in the digital and social media age.

Real-time multimedia transmit services like internet broadcasting, web-based education, chatting, conference, circumference observation etc. by using internet are given a great deal of weight on most recently internet services. In these way, various internet services are presented and there applications are also gradually spreaded because of improvement MPEG and streaming processing techniques. But currently internet service is a development of system which has independent function of above services. And a research and development of system which have a multipurpose internet service are insufficiency. In this paper, we design and develop system(RealCam SUN A/V) for transmitting images and voices based on MPEG4 streaming. As a result of our research, it made possible to transmit images with 15 frame/sec in 160×120 frame size at 56Kbps and 30 frame/sec in 640×480 frame size at 512Kbps. And also we can apply this system as multipurpose function to circumference observation and internet broadcasting etc., by transmitting voices, images and control signal simultaneously.

This study investigates the relationship among interactivity, telepresence, flow, and future behavior intention in internet shopping. Respondents were female consumers age 20 to 30. These consumers are regarded to have experience in internet shopping. 500 samples were used in this research. For data analysis, descriptive statistics, factor analysis, ANOVA, and multiple regression analysis were used for this study. As the result, interactivity, telepresence, and flow affect future behavior intention. Flow is the most influential variable affecting the future behavior intention. It implies that hedonic shopping experience (aroused by flow) can increase the future behavior intention of consumers. Consumers can operate and change the product image with convenience by encouraging interactivity between the internet fashion shopping mall and consumers. Through the technology, the experience 'flow' of consumers can provide a sense of telepresence as if they were shopping in a real store. Consumers may feel unconscious of the passage of time and feel fun, free, and original. Therefore, the internet shopping mall should pay attention to what customers demand and reflect it through e-mail, real time chatting, and text messages. In addition, rich product information such as detailed images should be supplied to help customers visualize looks.

With the remarkable progression of network and the sophistication of contents, we now see various ways of communication methods in World Wide Web. In such trend, 3D web deserves our attention, which is applied for various areas such as education, game, chatting, e-commerce. Among those, by using 3D contents, e-commerce, especially the customized e-commerce, can give users more rich information about products. However, most of current 3D e-commerce sites are adopting a mere tool-based methods without considering contents and interaction required for the customized e-commerce. So, this paper proposes the direction of developing 3D interaction program for the customized e-commerce, based on a study on the required information elements about products and the interaction of controlling those factors. The evaluation to compare with the existing program is follows by the development of practical program, to give more persuasive reasons on the advantages of 3D e-commerce program.
