The purpose of this study is to understand the value of Fahrenheit 451 by Ray Bradbury as the second most favored 'One Book', and the goals of the communities which selected this particular book. A total of 53 'One Book' programs from 2001 through 2014 and 136 TBR programs from 2007 through 2015 selected this book as 'One Book' to read. In this study, 270 programs in TBR 2008/09, and more than 240 programs in TBR 2014/15 and several 'One Book' projects were analyzed. The results confirm the significance of book discussions and movie showing, the focus on such subjects as censorship, banned books, and freedom of expression, etc., and a close relationship between the diversity of programs and cooperation with community members.

통신망의 발달로 다양한 인터넷 기반 기술들이 등장함에 따라 현재는 데이터뿐만 아닌 음성에 대한 부분도 IP 네트워크를 통해 전송하려는 움직임이 발판이 되어 VoIP(Voice Over Internet Protocol)라는 기술이 등장하였다. SIP(Session Initiation Protocol) 프로토콜 기반 VoIP 서비스는 통신 절감 효과가 큰 장점과 동시에 다양한 부가서비스를 제공하여 사용자 수가 급증하고 있다. VoIP 서비스는 호(Call)를 제어하기 위해 SIP 기반으로 구성이 되며, SIP 프로토콜은 IP 망을 이용하여 다양한 음성과 멀티미디어 서비스를 제공하게 되는데 IP 프로토콜에서 발생하는 인터넷 보안 취약점을 그대로 동반하기 때문에 DoS(Denial of Service) 및 DDoS(Distribute Denial of Service)에 취약한 성향을 가지고 있다. DDoS 공격은 단시간 내에 대량의 패킷을 타깃 호스트 또는 네트워크에 전송하여 네트워크 접속 및 서비스 기능을 정상적으로 작동하지 못하게 하거나 시스템의 고장을 유도하게 된다. 인터넷 기반 생활이 일상화 되어 있는 현 시점에서 안전한 네트워크 환경을 만들기 위해 DDoS 공격에 대한 대응 방안이 시급한 시점이다. DDoS 공격에 대한 탐지는 매우 어렵기 때문에 근본적인 대책 마련에 대한 연구가 필요하며, 정상적인 트래픽 및 악의적인 트래픽에 대한 탐지 시스템 개발이 절실히 요구되는 사항이다. 본 논문에서는 SIP 프로토콜 및 공격기법에 대해 조사하고, DoS와 DDoS 공격에 대한 특성 및 종류에 대해 조사하였으며, SIP를 이용한 VoIP 서비스에서 IP 분류와 메시지 중복 검열을 통한 DDoS 공격 탐지기법을 제안한다.

The years from 1895 to 1915 marked an important period in Korean because it was the start of modern education during which a new school system was developed. In particular, the Government made laws and rules concerning the use of textbooks in schools. In this research information about books in use in schools was obtained from the {School Textbook List} which was drawn up during this period. Science textbooks printed in Korea from 1895 to 1915 were control1ed in their use by the Ministry of Education and the Government General of Chosen. They used the Private School Ordinance, Regulations for Official Examination of Textbooks in 1908, and Law of Publication in 1909 as the main means of controlling textbooks. The official examination of textbooks under the Japanese rule of Korea resulted in an increasing number of science textbooks being banned. While science textbooks had enjoyed more freedom from control by the Government General of Chosen than other textbooks, the situation changed significantly as Japan to intensify the control of all kinds of textbooks in Korea.

Online communities, such as Internet portal sites and social media, have become popular since they allow users to share opinions and to obtain information anytime, anywhere. Accordingly, an increasing number of opinions are manipulated to the advantage of particular groups or individuals, and these opinions include falsified product reviews and political propaganda. Existing detection systems are built upon the characteristics of manipulated opinions for one particular time period. However, manipulation tactics change over time to evade detection systems and to more efficiently spread information, so detection systems should also evolve according to the changes. We therefore propose a system that helps observe and trace changes in manipulation tactics. This system classifies opinions into clusters that represent different tactics, and changes in these clusters reveal evolving tactics. We evaluated the system with over a million opinions collected during three election campaigns and found various changes in (i) the times when manipulations frequently occur, (ii) the methods to manipulate recommendation counts, and (iii) the use of multiple user IDs. We suggest that the operators of online communities perform regular audits with the proposed system to identify evolutions and to adjust detection systems.

This study compares the Korean and U.S. media's coverage of the No Gun Ri massacre, analyzing their usages of sources in the stories and explaining by the perspective of media sociology why they differed in them. For the comparison with the AP's report, we selected only the reports of the Korean media which dealt with the incident itself. It was found that most of the Korean media utilized a very small number of sources, and that they relied on the victims alone. In contrast, the AP's sources were much more numerous drawn from both the victims and offenders. As a result, the Korean media failed to ensure the 'diversity of sources' and to illuminate the whole picture of the incident, although they had started to report it far earlier than the AP. From the depth interviews with the reporters, through the framework of media sociology, it was found first at the personal level, that the difference was brought about by the divergent news evaluation. It seemed that the Korean journalists regarded the incident with relatively lower news value than their U.S. counterparts. Next, at the intra-organizational level, it was conceded, neither did the Korean new media have so flexible news collecting system, nor so murk man-power and resource as the AP, which were required for the coverage of such an incident. The Korean media had not established the convention to utilize various sources with conflicting interests. Last, at the extra-organizational level, the Korean news media's coverage was still influenced by the self-censorship mechanism due to the ideologies of 'pro-Americanism' and 'anti-communism', even though the democratization of Korean society itself enabled the sensitive incident to be dealt with eventually by the media.

In the early 2012, European Union proposed new legal framework, including the right to be forgotten, for the protection of personal data. The new Proposal articulates kind of sweeping new privacy right and there has been debates on its potential threat to free speech in the digital age. While the situation is similar in Korea, I want to introduce the right to be forgotten in the Proposal. Then, I will analyze current legal system in Korea regarding the new privacy right and suggest some guidelines in searching direction for the coming legislation with respect to the right to be forgotten. The right to be forgotten should not have been promulgated without considering fully its effect on the free speech, especially in the society where the voice toward direct democracy or movement toward participation of the citizen, mainly through cyber space or Social Network Services, has risen much higher in Korea. Especially, the new right seems not to cover the control of data subject on a third party where the third party expressing his opinion by posting himself other's personal data on his blog or others.

The representative example of the business model on internet environment, the business of the Naver, Empas and Google which provides information retrieval service is the internet portal. The portal sites provide information retrieval service which provides users information what they want to find, that is a huge social contribution. The portal site which provides a search service leads much problems. Consequently, the regulation against information retrieval is asserted powerfully in spite of the public interest. Namely, the regulation regarding the search business owner is tried. Finally, portal business owner puts the social responsibility as OSP. But, there is a doubt that portal business owner who has much problem which occurred on the portal site indirectly has responsibility directly. That is duty on portal site owner the censorship on the contents transferred. So, this thesis researches on the social critical opinion relating with a information retrieval from the legal side against the problem of the Internet.

This article presents a historical account of media role in the transition and consolidation period of democracy. Despite the assumption that media plays a important role in the construction of democracy, it is less clear how the media can affect the process of political change itself. This article seeks to answer some of these question, based on the Mill's macro-social comparative 'method of difference' of Korea and Spain. It is widely agreed that both states achieve democracy through transaction from above(pacts). Media role, however, differs significantly in accordance with authoritarian legacies and civic representativeness of the pacts. Whereas Korean dailies is deepening given market oligopoly and prior practices after democratization, Spain dailies market entirely changed in both structural and spiritual respects. As a result, Korean dailies substantially lacks in civic representativeness as before, contrary to Spain. Spain television settled a sort of the external pluralism. Korean television is pursuing the BBC type of internal pluralism. In Korea, television is more commercial than Spain. Consequently, Spain media serve the consolidation of democracy more than Korea on the whole.

When looking at the online copyright infringement, the advertisements have served as a revenue source. Recently, copyright holders and state agencies have requested to stop and withdraw posting the ad. in order to prevent copyright infringement. This way is very easy and efficient. However, the problem is that it is not clear whether the request is appropriate. For the request to be valid, posting the ad. should be a kind of indirect infringement, or if not, it must have a suitable reason. If there is no basis or reason for the two, the request should not be asked recklessly. In the US relevant cases, something more than simple relationship with direct infringers or more material contribution to the direct infringement is required to impose secondary liability for copyright infringement. However, just posting the ad. cannot be considered as the close relationship and moreover, it is not material contribution. Thus, posting the ad. is not secondarily liable for copyright infringement. In addition, the bills which was proposed in 2011, so called SOPA and PIPA, had a provision which can stop and withdraw the ads in the piracy sites. Its opponents raised the following problems: withdrawing the ad. is the censorship, gives the burdensome to the sites, and causes the imbalance due to the overload protection of copyright. Also, under the ad blocker case, to remove the ad. discretionally consists of illegal activity or copyright infringement. As a result, because the request to stop and withdraw posting the ad. is not reasonable, the request should be asked carefully.

The purpose of this study was to verify the effects of personal characteristics and military service experience on their entrepreneurial intention. Hypotheses were developed based on extant literature and tested using the data collected by surveys to retiring officers and NCOs. The conclusions drawn from the analysis were as follows. First, the major factors affecting the voluntary self-employment intention are role model, perceived desirability, and working environment. Second, the biggest difficulty in preparing to start a self-employed business is the lack of founding capital and entrepreneurial information. Third, the respondents believe that military career is not helpful in starting a business. Fourth, there were many negative perceptions that the education and training from the military does not help the self-employment. As a result, it is believed that improvement of entrepreneurial education in the military and expansion of entrepreneurial education during service are required. Especially, the education focusing on self-employed entrepreneurship should be improved. It is recommendable that the entrepreneurial education now being carried out by the Military Outplacement Training Institute should be extended not only during the outplacement period but also the normal service period, thereby increasing the intention of the military official.
