  • The purpose of this study is to examine middle school teachers' use of technology and problem-based learning (PBL) in their teaching practice. Factors related to teachers' use of technology and PBL are also investigated including: teachers' computer and Internet skills, feelings of preparedness to use the Internet, attitudes toward the use of web resources, pedagogical beliefs, science teaching efficacy, and the use of general teaching strategies. Twenty-seven middle school science, math, and technology teachers participated in the study. Research results describe the participants as slightly proficient in computer and Internet skills, positive toward use of web resources, and neutral on feelings of preparedness toward use of computer and the Internet. Participants also tended toward constructivist pedagogical beliefs and used various teaching strategies. They, however, reported low science teaching efficacy. Teachers' use of computers and the Internet correlated with pedagogical beliefs and feelings of preparedness toward the use of computers and the Internet. The study also found the relationships between the use of PBL and teachers' computer and internet skills, pedagogical beliefs, and the use of general teaching strategies. Also discussed are meaningful implications for teachers' professional development, especially for the programs designed to facilitate the use of web-enhanced PBL.

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 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.

  • The purpose of this paper is to investigate the diffusion process of mobile internet use in Korea and to explore the determinants driving MIU. A survey was conducted to collect data to empirically assess the research model. In total, 543 usable responses were collected using a questionnaire derived from previous research. Both the structural equation model and partial least squares were used to study the model concerning different user groups. Findings, The results indicate that there are significant differences in the users' perceptions of mobile internet usage during its different innovation diffusion stages. Of the determinants, perceived enjoyment is the most important predictor of mobile internet use. In addition to motivating users by making services more enjoyable, the findings suggest that practitioners should take the differences of adopter groups into account.

  • This study was designed to provide a better understanding of Korean female Internet users' intention to search for information regarding apparel goods and to shop for these goods. Shopping orientation, familiarity, and prior purchase experience were seen as influencing the intention to use the Internet for information search. An important aspect in the search habits that a consumer adopts in gathering information for their buying decisions was Internet shopping attitude. The objective was to predict apparel shopping in terms of prior Internet shopping experience, familiarity, intention to search information via the Internet, and shopping orientation. Internet shopping attitude, familiarity, prior purchase experience, and intention to use to search information were significant in predicting Internet apparel shopping. The most important determinants which influenced Internet shopping were attitude toward Internet shopping and intention to search. In considering the results of the present study, one should recognize the inherent limitations associated with generalizing these findings beyond the sample and the consumer products examined which in this study were apparel goods. Also this study focused on female computer users only. Therefore, future research should utilize more broadly based samples and refine the instrument to distinguish among different apparel products. This study does provide some information that should be helpful to retailers targeting the women's online apparel market.

  • The VoIP (Voice over IP) is being used world-widely and already put to practical use in many fields. However, it is needed to ensure the security of VoIP call in special situations. It is relatively difficult to eavesdrop commonly used PSTN network in that a 1:1 circuit connects it. However, it is difficult to ensure the security of a call on Internet because many users are connected to the Internet concurrently. This paper suggests a new model for Internet telephony to prevent eavesdrops, using VoIP (using SIP protocol) with the use the VPN protocol and establish the feasibility of its practical use comparing it with the conventional Internet telephony.
