A lot of problems with information education may be obstacles to the sound development of the information society, but they can't stop this social change. As the social environment has changed, our viewpoint and teaching methods have been changed. The techniques of the network are the force of this information society, and personal education is needed for a sound future. We should think about the problems and side effects of these changes and work out the teaching and learning methods which are most suitable for our current society. We need to be quick to discover ways to remove the problems of the information society. In this paper, we develop courseware for network etiquette and apply them to the education curriculum.

Various wireless communication devices or network such as WRAN and WLAN will coexist in the TVWS(TV White Space). Because of this coexistence, the wireless devices which use the TVWS have to avoid interfering to not only licensed TV receiver and wireless microphone but also homogeneous or heterogeneous TVBD(TV Band Device)s. In this paper, we propose two frequency sharing methods for the coexistence of WLAN and WRAN in terms of interference reduction and throughput enhancement in both homogeneous and heterogeneous networks. One is the WRAN spectrum etiquette to provide more wide bandwidth for WLAN users and the other is the WLAN frequency selection methods to improve the throughput performance. The simulation results have confirmed the throughput improvement of the proposed methods. Moreover, the proposed methods is also applicable to improve the throughput performance and reduce interference of similar systems working in a cognitive manner.

청소년의 인터넷 사용횟수가 급속히 증가하면서 그에 따른 역기능이 사회문제가 되는 시점에서, 학생들이 자신의 컴퓨터 활용 실태를 스스로 검토해 볼 수 있으며, 문제점이 있는 활용실태에 대한 현실감 있는 해결방법을 스스로 찾아볼 수 있는 기회와 환경을 제공하는 것이 필요하다. 청소년의 컴퓨터 활용과 관련한 역기능의 문제를 청소년 본인이 가장 정확하게 파악하고 있으며, 토론활동을 통하여 가장 효율적인 해결방안을 제시할 수 있는 대상도 청소년이다. 따라서 정보통신윤리 의식의 함양을 목적으로 학교 수업 시간에 적용이 가능한 웹 사이트 형태의 네티켓 코스웨어를 개발하여 적용하고자 한다.

Cyberbullying has been an emerging issue in recent years where research has revealed that users generally spend an increasing amount of time in social networks and forums to keep connected with each other. However, issue arises when cyberbullies are able to reach their victims through these social media platforms. There are different types of cyberbullying and like traditional bullying; it causes victims to feel overly selfconscious, increases their tendency to self-harm and generally affects their mental state negatively. Such situations occur due to security issues such as user anonymity and the lack of content restrictions in some social networks or web forums. In this paper, we highlight the existing solutions, which are Intrusion Prevention System and Intrusion Detection System from a number of researchers. However, even with such solutions, cyberbullying acts still occurs at an alarming rate. As such, we proposed an alternative solution that aims to prevent cyberbullying activities at a younger age, e.g., young children. The application would provide an alternative method to preventing cyberbullying activities among the younger generations in the future.

Consumer Portal is defined as "a combination of hardware and software that enables two-way communication between energy service provider(ESP, like KEPCO) and equipment within the consumer's premises". The portal provides both a physical link(between wires, radio waves, and other media) and a logical link(translating among language-like codes and etiquette-like protocols) between in-building and wide-area access networks. Thus, the consumer portal is an important, open public shared infrastructure in the future vision of energy services. In this paper, we describe a new methodology for local communication and computer network capacity design of consumer portal, and also presents capacity calculation method using a network system limitation factors. By the approach, we can check into the limitations of existing methods, and propose an improved data processing algorithm that can expand the maximum number of the networked end-use devices up to $30{\sim}40$ times. For validation, we applies the proposed methode to our real system design. Our contribution will help electrical power information network design.

RConsumer Portal is defined as "a combination of hardware and software that enables two-way communication between energy service providers(ESP, like KEPCO) and equipment within the consumer's premises". The portal provides both a physical link(between wires, radio waves, and other media) and a logical link(translating among language-like codes and etiquette-like protocols) between in-building and wide-area access networks. Thus, the consumer portal is an important, open public shared infrastructure in the future vision of energy services. This paper presents an XML based standard specification of service-oriented, open protocol for consumer portal system architecture. In the framework level, the XML protocol provides a useful bridge between services and platforms. The proposed standard protocol has been implemented into our developing consumer portal pilot system. The results imply the potential of global standards for consumer portal system by its minimum overhead in network and processor. The reposed XML is designated psXML in this paper.

The present study examined factors for current conditions of dental office manager in Korean dental clinic. 108 randomly selected members of Korean dental office manager responded to a questionnaire. A survey was conducted for a month from 1, June 2008, and the chi-square test and ANOVA were used in the statistical analysis. The findings of the study were as follows: The number of members depending on the type of occupation dental hospital was the highest number of members, members of the dental hygienist at the dental hospital number significantly higher. The career of dental office manager followed by 1-5 year in dental hospital, 5-10 year in dental network, 1-5 year in dental clinic accounting for 48%, 52.9%, 69.4%. The difficulty during duty performance are high expectation of owner in dental hospital, learning of dental office manager duty in dental clinic. The duty of dental office manager followed by customer service, appointment scheduling, telephone etiquette, treatment plan. Henceforth, it needs to standardize the Korean name of dental office manager and duty. Also, it have to an official certification system.
