This research examines the recent increasingly intensified non-reporting phenomenon by the press in South Korea and its legitimacy and validity. Non-reporting denotes cases in which the press does not report on significant issues in society. Although journalism scholars have raised this question, it remains unaddressed through case studies and formal criticism. This research compares the reporting and non-reporting by major media groups of cases related to the surveillance of civilians by the National Intelligence Service and the Defense Security Command under the Ministry of National Defense. This research specifies that the non-reporting phenomenon relates not to the ability to report, but to willingness to report, due to intervention by political factionalism of media groups. The non-reporting phenomenon results from the press ignoring their basic responsibility stemming from journalistic ethics and their social responsibility to fulfill their readers' right to know. Accordingly, this research revealed that the non-reporting phenomenon cannot be justified through diverse theoretical discussions and the journalistic code of ethics. Through the logical framework of public opinions and diverse empirical data to support it, this research demonstrates that the non-reporting phenomenon produces not unhelpful, but harmful effects to resolutions to ideological dissent in South Korean society.

Recently, development of technologies for autonomous vehicles has been actively carried out. This paper proposes a computer vision system to recognize lanes, crosswalks, and stop lines for autonomous vehicles. This vision system first recognizes lanes required for autonomous driving using the RANSAC algorithm and the Kalman filter, and changes the viewpoint from the perspective-angle view of the street to the top-view using the fact that the lanes are parallel. Then in the reconstructed top-view image this system recognizes a crosswalk based on its geometrical characteristics and searches for a stop line within a region of interest in front of the recognized crosswalk. Experimental results show excellent performance of the proposed vision system in recognizing lanes, crosswalks, and stop lines.

There are no specific criteria deciding what type of crosswalk installs although 4 typed crosswalks at signalized intersections classify according to number of stop line, spacing from the border of intersections and existence of traffic islands or not. Accidents involving pedestrians at signalized intersections are classified by type of crosswalks by traffic volume, pedestrian volume at crosswalk, intersection geometry and phase in view of pedestrians' safety at 50 intersections in Gwangju. The Multiple regression models are applied to express the pedestrian accident rate. In addition, process deciding what type of crosswalk installs which includes accident rate involved pedestrian is changed into number of accident is represented to reduce number of accidents. This paper presents what type of crosswalk installs in order to reduce pedestrian involved accidents at new or existing crosswalk.

This paper examined how consumers' attitude toward the telecommunication expense was affected by news reports through the experiment. Participants were randomly assigned to one of four group (control group, high-expense-claimed-media group, low-expense-claimed-media group, and both-exposed-media group), and asked to indicate credibility & neutrality toward media report, similarity between media report, and their own thought, their attitude toward the telecommunication expense. The result of ANOVA showed that the high-expense-claimed-media was perceived more credible and neutral than the low-expense-claimed-media. ANCOVA was conducted to eliminate the impact of similarity between media report and their own thought on the evaluation of credibility & neutrality toward media report, and the result showed that there was no difference. Also, participants evaluated the telecommunication service so expensive, regardless of what kind of media reports they were exposed. We found that consumers' prior belief, which telecommunication service was expensive, might interrupt consumers' learning process for new information from media. To resolve the social pressure about mobile service rate-cutting, it is necessary to investigate how to dampen consumers' stereotype about the telecommunication expense. The future research using the framing effect could be considerable.

최근 대리수술 (무면허의료행위)과 같이 환자의 안전을 위협하는 사건들이 언론에 보도되고 있다. 대리수술 방지를 위한 수술실 감시카메라 장치 도입 등의 대안이 등장하고 있지만, 의료계의 거센 반발로 인해 시행되기에는 현실적인 어려움이 있다. 하지만 대리 수술과 같은 사건이 빈번하 발생함에 따라 의사에 대한 사회적 신뢰도가 추락하고 있다. 본 논문에서는 근거리 무선 통신 장치인 비콘(Beacon)과 생체인식 중 안잔하고 신뢰할 수 있는 홍채인식을 결합한 의료진 신분 확인 시스템을 제안한다. 이 시스템은 홍채인식을 통해 사용자 인증을 수행함으로써 1차적인 신분확인을 하고 비콘을 통해 의료진이 수술실에 있다는 것을 증명한다. 또한 무작위 주기로 홍채인증을 수행하여 의료진이 초기 인증만 수행하고 수술실을 떠나는 경우를 방지함으로써 집도의에 대한 환자의 신뢰를 보장한다.

This paper explores the determinants of re-employment of retired military personnel who served more than ten years in Korea. Recently, the re-employment rate of veterans is less than 30%. Considering the reduction in military forces in future, this very low rate of re-employment may be one of important social and economic problem. Using a survey and econometric analyses, we generate several important results. First, spouses' income is higher in the group who chose to run their own business than in the group who decided to become salary workers. Second, those who gave economic activities had longer the period of military service, higher ranks, and higher rate of being in bad health. Third, the longer the military service period is, the shorter the period of job search. And those who not taking the program of vocational guidance have short search period. If, however, one was more educated or one served longer in Seoul area, then she is more likely to have a longer search period. These results imply that the current important factors in government policies for veterans such as vocational guidance programs, information for employment, and military experience should be improved to be more oriented to the requirements of employers.

The purpose of this study was to investigate consumers' perceptions of sodium saccharin in social media. Data was collected from Naver blogs and Naver web communities (Korean representative portal web-site), and media reports including comment sections on a Yonhap news website (Korean largest news agency). The results from Naver blogs and Naver web communities showed that it was primarily mentioned 'sodium saccharin-no added' products, properties of sodium saccharin, and methods of reducing sodium saccharin in food. When media reported the expansion of food categories permitted to use sodium saccharin, search volume for sodium saccharin has increased in both PC and mobile search engines. Also, it was mainly commented about distrust of government, criticism of food product price, and distrust of food companies below the news on the news site. The label of sodium saccharin-no added products in market emphasized "no added-sodium saccharin". These results suggest that consumers are interested in sodium saccharin and especially when media reported the expansion of food categories permitted to use it. Consumers were able to search various information on sodium saccharin except safety or acceptable daily intake through social media. Therefore media or competent authority should report item on sodium saccharin with information including safety or acceptable daily intake based on scientific background and reference or experts' interview for consumers to get reliable information.
