The results show that bonding, shared value and reciprocity has statistically significant effect on the trust of online customers and trust has a positive influence on customer satisfaction and loyalty in Internet shopping malls. Theoretical. managerial and research implications are discussed.

표현과 소통으로서의 인터넷 댓글과 그 책임에 관한 일 고찰

유일상(Il Sang Ryu),유계환(Kye Hwan Ryu) 한국언론법학회 2011 언론과 법 Vol.10 No.2

이 글은 인터넷 댓글을 둘러싸고 자주 빚어지는 표현의 자유와 인격권의 갈등에 대한 문제의식에서 출발하여 하버마스의 소통행위이론에 나타나는 법사상과 언어철학에 바탕하여 댓글의 성격을 분석하고 갈등의 조정방안을 연구한 결과이다. 인터넷은 누구나 발신자와 수신자가 될 수 있는 사이버 공간을 만들고 이 공간에의 접근과 이용이 과거의 매스미디어와는 다른 양상을 보여주고 있다. 인터넷 댓글은 익명성이라는 장막을 이용하여 타인의 명예훼손, 모욕 또는 프라이버시를 침해하는 일 등이 잦으므로 표현의 자유를 보장하는 헌법적 문제와의 충돌이 빈번하나 개별적 비교형량으로는 절차도 복잡하고 정보의 전달을 방해할 수도 있다. 논문의 주요내용을 정리하면 다음과 같다. 첫째, 이상적인 소통상황에서는 표현의 자유가 커뮤니케이션의 권리 수준으로까지 더욱 확장되어 보장되어야 하지만 댓글은 언어학적으로 여러 가지 범주를 포함하므로 그 물리적 발성, 관습적 발화는 물론 그 기대효과 등을 충분히 분석하여 행위당사자 및 인터넷서비스제공자 등에게 책임을 물어야 한다. 둘째, 댓글이 공적 관심사와 관련하여 공적인물에 대한 호오( ) 감정을 드러내지만 하버마스의 용례에 따르면 우리의 생활세계가 식민화되어 많은 사적 영역이 공적 영역으로 포섭되는 현대사회에서는 종래 미국 판례에 나타나는 공인이론과 판례가 그 설득력을 잃을 수 있다. 셋째 댓글은 하버마스의 이론체계로 유추하면 일종의 스피치 행위로 볼 수 있으므로 표현적 사실진술적인 것은 더욱 자유로워야 하고 스피치도 일종의 발화행위라는 행동으로 볼 수 있으므로, 우리 법원이 전적으로 수용하고 있지는 않으나 공인 대상의 스피치 보호 장치인 미국의 현실적 악의의 법리를 도입하여 댓글작성자 인터넷서비스제공자의 의중을 파악하는 방법으로서 수용할 것을 제안한다. 결론적으로 사이버 공간에서 표현의 자유와 인격권의 조화를 이루는 이상적 커뮤니케이션 상황을 이룩하기 위해서는 더 많은 논의와 사회적 합의가 필요하다고 본다.

This paper has two primary objectives: (1) to propose a comprehensive theoretical model that incorporates valuable insights from two complementary streams of research, and (2) to empirically test the model that explain the task-media fit and satisfaction of customer contact center users. The comprehensive model was tested using LISREL analysis on the sample of 232 users who have experience with the customer contact center. The model was supported in customer contact center context, accounting for 29% of the variance in the task-media fit, 53% of the variance in the perceived ease of use, 61% of the variance in the perceived usefulness, and 52% of the variance in the user satisfaction. The results showed that the task-media fit, the perceived ease of use, and the perceived usefulness play a significant role in influencing the user satisfaction of the customer contact center. In addition, task analyzability, media richness, media interactivity, and self-efficacy were found to influence the task-media fit. The paper concludes with discussions and implications for researchers and practitioners.

반론권제도와 그 개선방안

유일상(Ryu Il-Sang) 한국헌법학회 2003 憲法學硏究 Vol.9 No.4

This paper is to suggest the policy guidelines how to settle down the right of reply efficiently. The guidelines for the right of reply should be based on the analysis and interpretation of the Korean constitution and relevant Acts. The right of reply harmonizes the press freedom and privacy protection at the point that individuals express more speech through the related mass media. In Korea, the right of reply was adopted by the name of claim for rectification reporting under the Basic Press Act in the 5th Republic. After the abrogation of the Act in 1987, the clause was succeeded to the Registration of Periodicals Act and the Broadcasting Act. Now, the newly introduced rectification reporting system should take the arbitration process since 1995, while the old system should request compulsory arbitration for the report of reply. Press Arbitration Commission that is evaluated as some ambiguous institution internationally takes the central role for this process. It may look like that the journalism is not regulated by court but by the semi-governmental organization that is sponsored by Broadcasting Development Fund raised by Korean Broadcasting Commission. However, the commission regulates actually the freedom of the press and the speech indirectly by the members appointed by the Minister of Culture and Sightseeing. According to the democratic participant normative theory, it is believed that free press and the equal opportunity will guarantee personal happiness when mass media promote to exchange one's roles between communicator and communicatee frequently. The conclusions of this paper IS induced according to the normative logical analysis. First, press and the broadcasting media should be allowed to exercise the right of reply separately. Second, the present right of reply that can restrain the freedom of journalism should be considered again whether it is constitutional. Third, the present Press Arbitration Commission should be reformed not to restrict citizen's right to know and should allow the self regulation of journalist to guarantee the free flow. Forth, in order to minimize suffering injury from published news story the period of prescription should be extended period for the excercise right of reply and rectification, but shortened for the publishing reply and rectification of original news story.

The main purpose of the study is to analyze exemption to disclosure clauses of the Information Disclosure Act of Korea and compare it with those of Japan, the United States and the United Kingdom. The method of legal research employed in this study include examining the precedent and legal reasoning. The major findings of the study are as follow; First, exemption to disclosure clauses in Korea are substantially different from those of the United States and share more similarities to those of Japan, although greatly influenced by the U.S. law. Meanwhile, in Britain, as many as 23 disclosure exemption clauses have been stipulated under the Freedom of Information Act, which ascribes it to the long-held tradition of administrative secrecy. Second, the 8 classified exemption to disclosure informations of Korea are not mutually exclusive, leaving much room for being interpreted arbitrarily by public agencies on the clauses from their own angles. Third, informations classified as confidential or exemption to disclosure are strictly protected under the current law in Korea. However, it is recommended, classification procedures of defining the scope of secrecy need to be supplemented and such exemption to disclosure clauses should be amended in a way that the substantiality of secrecy is verified, as the U.S. law mandates. Fourth, under the subterfuge of transparent administration of public affairs, authorities might overly restrict the disclosure, making it difficult to obtain information which should be readily accessible to the public. Fifth, in relation to protecting private information, exemtion to disclosure clauses which prohibit disclosing an personal name and resident registration number are deemed to be insufficient. Therefore, not only to protect privacy, but also to enhance basic rights of human-being for deciding on self-information disclosure, the specifically defined categories of personal information such as an individual's medical information, financial information, or educational information, would be a more efficient alternative. Sixth, while the disclosure exemptions of corporate information are restricted exclusively to manufactural and technical information in the United States, the Korean law seems to be overly protective by prohibiting disclosure of any business information interfering with corporate profit-making. Therefore, legislative revisions need be made so that interests of disclosure exemption can be tested ad hoc balancing against those of disclosure, as seen in Japanese law. Finally, Korea and U.S. laws show differences in defining exemption to disclosure information : Korea classifies information about real estate as a special exemption to disclosure, while oil and gas wells information critical for a public good is strictly confidential in the United States. As far as real estate information is concerned, just like Japan, disclosure of some informations may be required for the purpose of a public good so that Korean government can have some leeway to curve the rampant real estate speculation. This study may not only be set for the future amendment to the Information Disclosure Act which is relatively new in Korea but also resolve legal disputes more efficiently.

최근 스마트폰 사용자들이 급격히 증가함에 따라 다양한 사회적 문제점들이 발생되고 있다. 대표적으로, 과도한 스마트폰의 사용과 잘못된 이용습관은 `스마트폰 중독(smartphone addiction)`과 `스마트폰 질병(smartphone disease)`과 같은 새로운 사회적 문제점들을 야기시키고 있다. 본 연구에서는 이러한 문제들을 사전에 예방하기 위해 스마트폰 사용자의 패턴을 방향센서를 이용해서 수집하고 분석해서 스마트폰 중독 및 질병을 예방하는 시스템을 제안한다. 제안된 시스템은 사용자의 스마트폰 사용형태와 사용시간을 실시간으로 분석하여 위험수준에 도달하였을 경우, 사용자에게 이를 알려 줌으로써 사용자 자신이 사전에 위험을 인지할 수 있도록 하며, 자신의 의지로 스마트폰 사용을 절제하도록 하여 스마트폰 중독 및 질병을 사전에 예방할 수 있도록 제안한다. In recent years, in accordance with the rapidly increasing number of smartphone users, various social problems have started to occur. Examples of these problems are the overuse of smartphones and bad usage habits of smartphone users that can cause new social problems such as smartphone addiction and other smartphone related diseases. With the aim of preventing these social problems, this paper proposes a new smartphone addiction and disease prevention system. This system was developed by collecting and analyzing smartphone usage patterns. This proposed system analyzes the usage patterns and working hours of smartphone users in real time. If the detected smartphone usage patterns reach a dangerous level, the system will send warning messages to the user. This will enable users to recognize the unhealthy situation in advance by themselves. In addition, this solution could possibly prevent smartphone addiction and other smartphone related illness by preventing overuse and encouraging abstinence from using smartphones to the extent that it becomes harmful to the user.

The purpose of this study is to analyze customers’ satisfaction for the stiffness of outside panels of passenger cars. Including ‘satisfaction’, four affective variables were selected for rating affection of outside panel stiffness. About fifty customers evaluated the hood and trunk lid of nine midsize passenger cars with a developed questionnaire in the study. The stiffness of the hood and trunk lid for the nine vehicles was measured using stressstrain curves. It was found that customers were more satisfied as the slope of the stress-strain curves increased, and the decrease at a point in the curve had negative effects. In this study, the levels of satisfaction of outside panel stiffness were grouped by stress-strain curves, and it is likely that the affective quality of outside panel stiffness can be controlled by them. With the results of this study, the designers of outside panels are able to know how to make the stress-strain curves of panels for the desired level of satisfaction.
