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.

This study intends examine the relevance of factors with negative influences on anti-social sexual awareness formation in adolescents as per the concern of the parents of families with adolescents, as internet pornography exposure in adolescents lead to excessive indulgence in pornographic photographs, cartoons, videos, or fictions, or in video chatting with exposure of one's own body parts. For this, the factors of internet pornography exposure in the study subjects of adolescents were constructed into a multilateral model, and the structural equation model was analyzed. As the result of the study, the following conclusion were drawn. First, the most powerful factor influencing the anti-social sexual awareness in adolescents was, contrary to the concern of many, not the exposure to pornography through internet media, but personal characteristics such as sensation-seeking tendency and socio-environmental characteristic of differential association. Second, it is worth noting that the most major factor influencing intentional internet pornography exposure by adolescents is another form of pornography exposure. Third, whether intentional or unintentional, the internet-related variable influencing the internet pornography exposure was found to be the amount of internet usage. Fourth, the unintended internet pornography exposure was found to have no direct influence on the sexual awareness of adolescents, but it did have an indirect influence on sexual awareness mediated by intentional internet pornography exposure and existing-media pornography exposure. Based on these study results, the conclusion was drawn regarding the influence of internet pornography on sexual awareness in adolescents.

Method: The students in this descriptive survey on causal relations were 433 girls enrolled in middle schools selected by convenience sampling. The data were collected in November-December 2003 and logistic regression analysis was used to build a forecast model. Findings: The findings showed the following, 1) Individual factors such as grade, alcohol consumption, sexual experience and the frequency of exposure to pornographic materials, and 2) family factors such as parental living arrangement were significant factors. Conclusion and Recommendation: The experience of smoking among Korean middle school girls was associated not only with individual factors, but also with family factors, which exert a strong influence on health behavior. There is therefore a need for school-based smoking prevention programs, which deal comprehensively with these factors that influence smoking. It is recommended that a program be developed that will help to control the variables identified in this study along with follow?up study to verify the model.

This paper proposes on the acoustic signal processing blocking method of Internet pornographicl sites by calculating correlation values between prototype acoustic signals and input acoustic signals. Pre-existing blocking methods mainly focused on directory-based bled(fin and pornographic related words-based blocking. But these methods are not completely blocked the Internet harmful pornographicl sites by several situations. For this, this paper proposes the content-based blocking method which composes of the image-based blocking and the acoustic-based blocking. This paper, mainly, deals with the acoustic -based blocking method. Finally, the effectiveness of this system is demonstrated by several experiments.

This survey research investigates the relationship in adolescent attitudes toward sexual consciousness and intimate relationships according to their exposure to internet pornography. The results of the study indicated that 57.1% of the participants have experienced contact with internet pornography with most participants (48.7%) having first encountered internet pornography while in fourth, fifth or sixth grade. As students progress in school, their exposure to the internet increases thus increasing their potential to be exposed to pornography. Adolescents with no experience encountering internet pornography had a more positive attitude towards sexual consciousness, while adolescents with experience encountering pornography had more uninhibited libidos and were more open to romantic relationships. From the results above, there is a need for preventative measures against problematic behavior stemming from the influences of direct and indirect pornographic exposure on adolescent attitudes towards sexual consciousness and intimate relationships. Mental health services need to be provided for high risk adolescents addicted to pornography like mental health schools or help from specialists.
