This study was conducted with the purpose of understanding the factors that influence smartphone addiction on adolescents' school adaptation. The subjects were examined with a focus on students currently attending middle schools in Gwangju Metropolitan City, and data analysis was conducted using SPSS 26.0 to examine the factors influencing school adaptation, focusing on the inducements and forced inducements that lead teenagers to fall into smartphone addiction. As a result of the analysis, it was found that anonymity and desire satisfaction among the attractive factors leading to smartphone addiction have a negative impact on school adaptation, and the forcing factors that cause adolescents to become overly dependent on smartphones include online games, online chatting, online addiction, and social interaction. It was analyzed that both action and information search had a negative impact on adolescents' school adaptation. Based on the above results, policy recommendations were presented by considering the points pointed out by the two discovered factors.

This paper describes our experience to design and implementation of a collaborative system framework that allows to develop certain collaborative applications such as 3D animation, computer game, and industrial design. The collaborative system enables users, who located in geographically long distance, to do collaborative work in a single virtual space. The proposed system basically consists of client and server system. The goal of proposed system is to support scalability, portability, and platform independent. In order to achieve these, the server is implemented in Java platform and is adopted to the hybrid architecture which takes the advantages both in centralized and decentralized collaborative system. We construct the server base on its functional characteristics so called User Manager Server (UMS), Session Manager Server (SMS), and Information Server (IS), The UMS manages the users who are taking part in the collaborative operations. The SMS supports the conferencing in the proposed system. The IS provides the connection methods among the UMSs. For user's convenience, we implement the client using Visual C++ in Windows. We also expend the functions of 3D Studio Max to distributed environment by means of the plug-in module, and facilitate the chatting and white board functions as well.

There are two main purposes in learning map in the subject of social studies in understanding the map itself and growing the ability of construing connection and situation and reasoning by applying the map. However, the map learning leans to understanding the map itself in existing materials. Although there is an interaction between learners and the context, there is hardly any interaction between learners or between teachers. Therefore, this paper designs and implements the web-based map learning system using the constructivism to make the cooperative study possible through the interaction and to be able to teach the map learning based on learners. The characteristics of the system suggested in this paper are as below. First, learners study the basic factors of the map by themselves and enable them to give feedbacks after the evaluation. Also, it embodies to evaluate the context of study as a multiple question after studying the whole thing. Second, the participation is induced by bringing the interests of learners based on the web and the interaction between teacher and learner as well as between learners is strengthened by the bulletin board and chatting function. Third, the study of utilizing map is embodied by means of applying the study model of solving problems and suggesting useful tasks.

Objectives : To evaluate the degree of adolescent internet addiction, and investigate its relationship to the general characteristics, internet environments, and contents, especially the stress measured by the psychosocial wellbeing index-short form(PWI-SF). Methods : The data was obtained from self-administered questionnaires from 886 11th grade urban area students. The questionnaires consisted of general characteristics, internet user's environments, frequencies by internet contents, internet addiction test and PWI-SF. Results : The possible rate of internet use at home was 95.1%, and the area of most internet use was the home. The frequencies of internet game and porno site use were higher in males, with web searching and community uses higher in females. The total mean of internet addiction score was 56.8, and was higher for male than for female students. From multiple regression, as analyzed by the internet addiction score as a dependent variable, on-line friends, internet use times, years of internet use, frequencies of internet game, & porno site use, and PWI-SF scores were significant in male. Internet use times, the frequencies of internet game, chatting, community use, and PWI-SF score were significant in female. Four PWI-SF subscales(social role & self reliability, depression, general health & vitality, and sleep disturbance & anxiety) and internet addiction were significantly correlated in both male and female students, with depression having the most correlation. Conclusion : The results of this study suggest that intervention should be provided to prevent internal addiction, especially for coping with stress in Korean teenage students.

The collaborative learning has been considered as an efficient teaching model and under the recent basic learning environment, even face-to-face classroom circumstance rapidly increases the courses of blended learning which utilize the merits of e-learning environment. Nonetheless, the study on the strategy for systematic blended learning is quite scarce. In this study, the survey was done for developing the blended learning strategy, based on the collaborative learning model at the face-to-face environment and judging the satisfaction on the courses which the model was applied to. The survey consists of demographic questions, satisfaction in the whole courses, satisfaction in the collaborative learning under the blended learning environment and satisfaction in the blended learning strategy and support tools applied to each step of the learning. The result of this study is as follows. First, in response to the question that the blended learning can complement the face-to-face classroom courses, the respondents represented average 4.09 at 5-point Likert scale. And to the question whether the collaborative learning is more efficient under the blended learning environment than the face-to-face classroom, the response corresponds to 4.06 scale on the average. Second, as for the satisfaction in the blended learning strategy and support tools applied to the each step of the blended learning, the satisfaction degree is analyzed as high as over 4.0 on the average toward all the questions. Third, regarding the support tools used for the blended learning strategy, the learners consider the tools as most helpful in order of chatting, team community, mail & note and archive. Lastly, I would like to suggest that the study result should be highly reflected in constructing the collaborative learning module of learning control system in the future.

A video conferencing system provides sharing the conference environment for geographically dispersed computer users who use the audio and video information. But the conventional video conferencing systems have some problems which are dependent on specific software and/or hardware and bound the certain platform and network environment. Furthermore the participants must know the information about other participants before joining the conference session and they have to use the same video conferencing system. This paper describes design and implementation of the video conferencing system on the WWW to solve the mentioned problems. The conference applications are transmitted from a WWW server and executed in the participants Web browsers. The participant can carry out conference services by using only the web browser. The WWW server takes charge of conferencing management including the information related to the participants and provides supported conference tools such as whiteboard, chatting and multimedia controls. Therefore the participants can easily join the conference sessions and perform conference working regardless of network connection situations. We used the Java to implement the seamless session connections and interaction between the conference participants which are the most important when implementing the video conferencing system on the WWW and used the ActiveX technology about the audio and video controls to make it easy the hardware control.

Bei verschiedenen $Gespr\"{a}chen$ zwischen Frauen und $M\"{a}nnern$ sind mehrere Unterschiede in $Gespr\"{a}chsstrategien$ und -verhalten des jeweiligen Geschlechts zu beobachten. Herkemmlichen Ansichten nach $f\"{u}hrten$ $M\"{a}inner$ $Gespr\"{a}iche$ mit Frauen eher dominativ, $w\"{a}hrend$ Frauen eine deutliche Vorliebe $f\"{u}r$ kooperativ erlaufende $Gespr\"{a}che$ zeigen. Um die $G\"{u}ltigkeit$ dieser Perspektive zu $pr\"{u}fen$, wurden in dieser Albeit insgesamt $zw\"{o}lf$ Beratungsgesprache herangezogen. Daraus ergab sich, dass $M\"{a}nner$ im $Gespr\"{a}ich$ statistisch $h\"{a}ufiger$ die anderen $Gespr\"{a}chsteilnehmer$ unterbrechen. Da ein $Gespr\"{a}ch$ ein komplex vernetztes soziales Geschehen ist, sollte diese Statistik bei der Bestimmung der $Gespr\"{a}chsverhalten$ von zwei Geschiechtern keine entscheidende Rolle spielen. Im Anschluss daran habe ich mick mit Hilfe einiger im Internet gesammelten Daten, mit den $Gesp\"{a}chsverhalten$ bei der so genannten Online-Kommunikation befasst. Bei der Online-Kommunikation lassen sich zwei kontrastive verbale $Umg\"{a}nge$ der Geschlechtern beobachten, $n\"{a}mlich$ ein reibungslos ablaufendes IRC(Internet Relay Chatting) und eine $auff\"{a}llige$ Debatte, die mehrfache Konflikte zwischen den Beteiligten zeigt. Um diese $Ph\"{a}nomene$ auf der Basis der $Gespr\"{a}chsanalyse$ zu $erl\"{a}utern$, werden vol allem das Konzept der Kooperation beim $Gespr\"{a}ch$ und die Dynamik der $Gespr\"{a}chsstruktur$ erneut begriffen. $Schlie{\ss}lich$ werden die unterschiedlichen $Gespr\"{a}chsverhalten$ von Frauen und $M\"{a}nnern$ folgend wiedergegeben: Bei realen Face-To-Face-$Gespr\"{a}chen$ setzen Frauen den Schwerpunkt auf die emotionale und interaktive Kooperation, $w\"{a}hrend$ Manner ihn auf die kognitive Kooperation setzen. Dieser Sachverhait $\"{a}ndert$ sich aber bei der Online-Kommunikation. Auch Manner halten die emotionale und interaktive Kooperation $f\"{u}r$ wichtig und $f\"{u}hren$ mehr kooperative und reibungslose $Gespr\"{a}iche$ mit Frauen. Doch in einer Debatte um ein Thema $verh\"{a}lt$ sich jeder Beteiligte anders. Die moisten benutzen die Strategien, die den geringen Unterschied zwischen den Geschlechtern in Anfangsbedingungen $vergr\"{o}{\ss}ern$, und gleichzeitig die individuellen Unterschiede zwischen demselben Geschiecht verschleichen. Dadurch kann eine Debatte zwischen Geschlechten in Streit ohne Kompromisse geraten.

In this study, 1 have analyzed the state of the use of information technology by the at-risk children who are residing in Husan metropolitan area. The ultimate goal of this study is to help ensure the healthy development of the children and improve the quality of their lives in this information-oriented society. For this research, 1 surveyed 183 children living in an institution or a low-income family in Busan metropolitan area. The survey questionnaire was designed to obtain information on the respondents, socio-demographic characteristics, computer-related conditions of the immediate and social environments, patterns of computer and Internet use, their experience and degree of so called, Net-generation syndrome, Internet addiction disorder, changes in social and familial life caused by Internet use, and exposure to pornographic materials. The results show that 95.9 % of at-risk children in Husan own a computer, 60.9 % of those computers being Pentium Ⅲ. A majority of the children (74.9 %) are connected to Internet at a high-speed, using such devices as LAN, ADSL or cables. About seventy-six percent of the children have used a PC and Internet less than two years. In other words, a majority of them have not used those for a long period of time. The main results of the research are summarized in the following: There is a significant difference among at-risk children in terms of experiences in computer and Internet use according to their grade levels. There is a gender difference in the amount of time spent on computer and Internet. Boys spend more time every week on computer and Internet than girls do. There is a significant difference in the pattern of computer and Internet use, according to the type of their risk, and grade level. The so-called 'Net Generation Syndrome' is not serious in this group. A majority of the at-risk children think that Internet is more interesting than TV. They hardly shop on Internet, and they don think the advertisements on Internet are a serious problem. Also, unlike many people assumptions, their desire to communicate through on-line chatting was very low. They do not tend to buy computer game programs, and Internet Addiction Disorder was not pronounced among them. The at-risk children rarely had an exposure to pornographic materials in the cyber space. However, the exposure was more frequent for institutionalized children than children in low-income families. These results point to a need for a policy to improve the welfare of at-risk children and guarantee their right to information.
