This study has been designed to explore the preferences of interior space for those living in apartment housing. It also examines the relationships between preferences of interior space, such as storage space, organization type of LDK(the living room, the dining room, and kitchen), space facing south, an interior garden, the concept of each room and the characteristics of the consumers, such as age, educational background employment status of homemakers, occupation of the primary income provider, family-life cycle, total household income, the size of floor space, and homeownership. In conclusion, this study suggests that at the time of designing apartment housing units, serious consideration should be given to the built-in closets or storage space in the anbang and to the location of a child's room facing to the south of the dwelling, especially for the families with a child attending primary school or younger and higher education level of homemaker. This study also recommends that the organization of the living room, the dining room, and the kitchen should be varied according to the housing size and the age of homemaker.

This study aimed to explore the current status of playgrounds, children's libraries and youth centers as local community centers in support of children. Its data were collected from reviewing the relevant literature, interviews, surveys and web search. It was found that children's libraries were predominantly located in Seoul and Kyungki provinces. In comparison with other advanced countries, Korea had lower ratios of volumes of books and periodicals per the library user and of a number of staff per the user. It was also found that over a half number of playgrounds was placed in apartment areas. Since 1993, the long-term youth development plan has commenced the construction of various societal infrastructure such as local youth centers, counseling institutes, sex-culture centers and youth cultural zones. Based on these findings, some policy issues were raised.

An increasing number of children are now using the Internet. They are starting at a younger age, using a variety of devices and spending more time online. It becomes an important problem to protect the children in online environment. The Internet can be a major channel for their education, creativity and self-expression. However, it also carries a spectrum of risks to which children are more vulnerable than adults. In order to solve these problems, we suggested a binding model of user attributes for enhanced user authentication. We also studied the requirements and prerequisites of a binding model of user attributes. In this paper we described the architecture of binding model of user attributes and showed the effectiveness of the suggested model using simulation. This model can be utilized to enhanced user authentication and service authorization.

In this paper, we propose iZone system for safe walking of children. The proposed system recognizes the state that a child is down a roadway as a dangerous situation. And then it informs the surrounding adults and guardians of the child in the event of a dangerous situation. The iZone system consists of the iZone device that attaches to a child's bag or clothing, the iZone app for children, the iZone server, and external beacons. The proposed system uses the ultrasonic sensor of the iZone device and the GPS coordinates and external beacons information by the children's smartphone to determine the dangerous situation. The proposed system uses external beacons to calibrate the GPS coordinates. Moreover, it determines whether the child is down the roadway in sidewalk by measuring the height difference between the roadway and the sidewalk using ultrasonic sensor.

Purpose: The purpose of this study was to explore the parent related factors that influence internet game addiction among elementary school students. Method: Data was collected through self-administered questionnaires and descriptive statistics, t-test, ANOVA, correlation and stepwise multiple regression were used to analyze the data. Data survey was conducted with 739 conveniently selected students who were in grades 4, 5, and 6 of elementary schools in Seoul or Gyung-gi province. Results: The addiction groups were classified as general user group (84.3%), potential risk group (10.0%) and high risk group (5.7%). There were significant internet game addiction differences by gender, grade, expense of internet cafe, religion, school record, place where child played, economic status, and duration and frequency of game play. The addiction was negatively correlated to parents' attachment, supervision, attitude to child nurturing, and expectations regarding school study. The most significant variables were both parents' attitude to child nurturing, and mother's supervision. These three variables explained 20.7% of internet game addiction in elementary school students. Conclusion: These findings are expected to make a contribution to the creation of ideal interventions at school, home, and counselling centers to prevent internet game addiction.

Computer technology and Internet advances enable easy massive file transfer by messenger, email, and web hard service users this means that a child pornography file owner who is illegally possessing itself can quickly transfer that to other users However there are currently no specific ways to prevent or block the distribution of child pornography between messenger, email, and web hard service users. in this paper, we propose a method to prevent the distribution of child pornography using the MD5, SHA-1 hash value stored in the 'police Child pornography Profiling system' and to identify the child pornography suspects using the subscriber information. the user extracts the hash value of the file before distributing the file, compared it with police system, and if it has the same value, blocks the transmission of the file and sends warning to the owner. the service provider sends the subscriber information to investigation agency child pornography owners can conduct a quick and accurate investigation.

Although the number of child loss in commercial facilities has been growing recently, the prevention method for child loss are still lacking in the environmental aspect. This research examines the causes of lost child in behavioral aspects in order to develop a guideline to prevent child loss in U.E.C. The observational study on the behaviors of guardians and children was conducted in the U.E.C that is visited by many customers accompanied with children. Then the results of the observational study were marked on the behavioral maps. After analyzing the behavioral maps, the causes of child loss were determined by classifying into behaviors by age and behaviors by functional space. As a result, when guardian is unable to pay attention to child by doing something else such as making a purchase, or an inquiry, child may lose guardian by going towards the interesting factors or playing around. Moreover, if the spaces related to children are located at the node with high pedestrian density and open structure or the environment that is hard for the guardians to watch over their children, it will be easy for guardians to be inattentive to their children, and get separated from each other.

The purpose of this study is to develop the playground environment model for child care center by analyzing user needs of playground environment. To systemize the playground environment design factors and guidelines, we reviewed the previous research, actual measurement and observation were used as the research methodology. And to recognize the needs of users, the survey and picture survey was conducted to the staffs and children. The scope of survey included child care centers in Seoul and Daejeon, ultimately selecting 12 places in Seoul and 13 places in Daejeon. In terms of the survey period, actual measurement was conducted from June of 2006 to February of 2007, survey and picture survey was conducted from August to September of 2006. For analysis, we used SPSS 10.0 to check the frequency and percentage, as well as to perform cluster analysis. The findings of research can be summarized as below: 1. In playground environment, we observed the area of play ground and ground cover, the independence of play area, play equipment, and the composition of play area. The result of observation showed that while playground area varied widely, ground cover, play equipment, and the composition of play area turned out to be identical, regardless of the playground's area. Therefore, in order to classify various playground environments, we categorized them into 5 types, using the number of children and the area of play ground as a category. Type A had large facilities and small playground area. Type B had small sized facilities and large playground area. Type C had medium sized facilities and small playground area. Type D had medium sized facilities but large playground area. Type E had large sized facilities and large playground area. 2. On the other hand, staffs wanted a tunnel, playhouse, comprehensive play equipment, and a maze to be installed as play facilities, and there were requests for adventure play area and carpenter play area. The picture survey to children showed that they wanted equipments that can provide more thrill, adventure and challenge to them than the ones they see now. Therefore, existing child care center play environments must change from the monotonous and identical environments to the ones that can provide diversities, challenges, and adventures. In the contexts of 5 playground types suggested by this research, type B and D, E where the area of playground were larger than the legally required, should include various play areas and install appropriate play equipments and facilities. Type A and C where the area were small, should provide multipurpose play area to attract the various play behaviors of children.

Purpose: In this study, the Internet game addiction level was assessed, and parent-child attachment level associated with the addiction was analyzed. Method: From December 5 to 23, 2005, self-reported questionnaire data were collected from 990 Busan City elementary school students of the 5th and 6th grades. The questionnaire consisted of questions about their characteristic features in playing Internet games based on the K-scale developed by KADO. The data were analyzed using the SPSS WIN 10.0 program. Frequency, percentage, arithmetic mean, and standard deviation, $X^2$-test, ANOVA analysis and Scheffe test were used to analyze the data. Results: 1. With regard to the level of Internet game addiction, 71.2% of the students responded that they were general users, and 6.3%, at high risk for addiction. Mean scores were 103.3 for the high-risk group, 77.7 for the potential risk group, and 55.86 for the general user group. The total mean was 63.74. 2. Mean scores for parent-child attachment levels were 97.1 and 99.6 for father and mother, respectively. Conclusion: These results suggest that a collaborative program to educate and counsel parents to increase the parent-child attachment level needs to be established in protection and recovery programs for Internet game addiction.
