This study would verify the validity of two transmission technology, 'Clear QAM' and '8VSB'. 'Clear QAM' and '8VSB', the transmisson technology, have been suggested as the concrete alternatives in the situation that half of subscriber of multi channel tv service have been still out of benefit from digital convert. In this study, we have shown that the introduction of 'Clear QAM' and '8VSB' should ease economical burdens and information minority group without extra set-top box. But there is another concern that it should negatively affect on the contents industry by a devaluation of the multi channel tv service or by an infringement of copyright. In these reasons, it is still difficult to solve the related concern, though the government have to set up the politic goal for the related industry as well digital convert. This study suggested that Korea Communication Commission consider above-mentioned technology temporarily, and reconsider 'Clear QAM' around the completion of the digital convert project.

The purpose of this study is to examine the cases of social integration in immigrants in the Netherlands and to clarify the implications for Korea. The Netherlands is a country that implements social integration policies targeting foreign immigrants. We are preemptively implementing social integration policies for foreigners ahead of us. In this study, first of all, the literature on social integration for the immigrants in the Netherlands and the consultation on the experts were sought and the implications for the Dutch government 's social integration policy were sought. In addition, policy implications were derived based on the results of Dutch case analysis. First, the social integration program of the Dutch government mandated social integration programs for migrants, and the costs were also monetized, encouraging social integration. Also, when participation in the social integration program is passive, it imposes sanctions on migrants and emphasizes the responsibility of individual migrants. In addition, the Ministry of Internal Affairs is the control tower of the government's promotion system, and it has a platform for the unity of social integration programs in local governments. Based on the results of this analysis, the implications for the social integration policy of Korea were suggested.

Mobile devices have become an important channel for news content usage in our daily life. However, online news content readers' resistance to online news monetization is more serious than other digital content businesses, such as webtoons, music sources, videos, and games. Since major portal sites distribute online news content free of charge to increase their traffics, customers have been accustomed to free news content; hence this makes online news providers more difficult to switch their policies on business models (i.e., monetization policy). As a result, most online news providers are highly dependent on the advertising business model, which can lead to increasing number of false, exaggerated, or sensational advertisements inside the news website to maximize their advertising revenue. To reduce this advertising dependencies, many online news providers had attempted to switch their 'free' readers to 'paid' users, but most of them failed. However, recently, some online news media have been successfully applying the Pay-What-You-Want (PWYW) payment model, which allows readers to voluntarily pay fees for their favorite news content. These successful cases shed some lights to the managers of online news content provider regarding that the PWYW model can serve as an alternative business model. In this study, therefore, we collected 379 online news articles from Ohmynews.com that has been successfully employing the PWYW model, and analyzed the comparative importance of systematic attributes of online news content on readers' voluntary payment. More specifically, we derived the six systematic attributes (i.e., Type of Article Title, Image Stimulation, Article Readability, Article Type, Dominant Emotion, and Article-Image Similarity) and three or four levels within each attribute based on previous studies. Then, we conducted content analysis to measure five attributes except Article Readability attribute, measured by Flesch readability score. Before conducting main content analysis, the face reliabilities of chosen attributes were measured by three doctoral level researchers with 37 sample articles, and inter-coder reliabilities of the three coders were verified. Then, the main content analysis was conducted for two months from March 2017 with 379 online news articles. All 379 articles were reviewed by the same three coders, and 65 articles that showed inconsistency among coders were excluded before employing conjoint analysis. Finally, we examined the comparative importance of those six systematic attributes (Study 1), and levels within each of the six attributes (Study 2) through conjoint analysis with 314 online news articles. From the results of conjoint analysis, we found that Article Readability, Article-Image Similarity, and Type of Article Title are the most significant factors affecting online news readers' voluntary payment. First, it can be interpreted that if the level of readability of an online news article is in line with the readers' level of readership, the readers will voluntarily pay more. Second, the similarity between the content of the article and the image within it enables the readers to increase the information acceptance and to transmit the message of the article more effectively. Third, readers expect that the article title would reveal the content of the article, and the expectation influences the understanding and satisfaction of the article. Therefore, it is necessary to write an article with an appropriate readability level, and use images and title well matched with the content to make readers voluntarily pay more. We also examined the comparative importance of levels within each attribute in more details. Based on findings of two studies, two major and nine minor propositions are suggested for future empirical research. This study has academic implications in that it is one of the first studies applying both content analysis and conjoint analysis together to examine readers' voluntary payment behavior, rather than their intention to pay. In addition, online news content creators, providers, and managers could find some practical insights from this research in terms of how they should produce news content to make readers voluntarily pay more for their online news content.

에너지 문제가 세계적으로 정치, 경제, 기술, 즉 일반생활의 모든 분야에 있어서 가장 중요한 과제로 대두되고 있다. 이는 산유지의 지하에서는 계속해서 생산되고 있으나 무한정으로 원유가 매장되어 있으리라고는 생각되지 않는다. 현재 세계는 정치, 경제적 책략 때문에 석유의 생산부족 및 고가화되어 가면서도 석유의 고갈현상이 시작되어 21세기초에는 석유생산이 수요를 따를 수 없게 될 것 같다. 이러한 석유자원의 감소와 산유국의 정책변환에 따라 1973년 제 1 차 오일 쇼크에 이어 1978년말부터 제 2 차 오일쇼크를 가져와 70년대초 1배럴당 2-3달러에 불과하던 유가가 34달러까지 폭등하여 세계경제에 막대한 영향을 미쳤다. 본고에서는 현재 세계 에너지 자원의 매장량과 앞으로의 에너지 수요증가 및 석유생산의 예측 등을 살펴봄으로써 에너지의 심각성을 인식케하며, 또한 앞으로 에너지자원의 의존도가 가장 클 여러가지 대체연료에 대하여 이용기술의 현황, 대체연료로서의 적성 및 그 장래문제에 대하여 언급하고자 한다. 끝으로, 최 근의 에너지절약 방법으로 연구개발되고 있는 기관의 배기에너지의 유료이용, 신현 원동기의 에너지절약성 및 가변실린더수의 기란 등에 대하여 기술하고자 한다.

There have been gradually established paid using system on contents, such as sound source, webtoon etc, with which licences are systematically managed. However, rampant free sites still mostly relying on advertising revenue make difficulties on lots of contents developers and obstruct the protection of their resonable right. In this situation, we need systematic measures to protect copyright of authors and to maximize use of contents of users. Therefore, it is important to handle the convenience of digital contents distribution and the diversity of contents license(differentiating permission rate according to user's purpose, scope, service period etc), based on the need of contents users. This paper implies to guideline to install contents distribution platform of individuals and to apprehend the need and acceptability of users in order to activate digital contents transaction on individuals.

In accordance with the development of broadcasting, the style of using medium by users has been personalized in the propensity to consume. Recent advent of media convergence allowed users of medium to decide the received environment for their needs, thereby the position of users has become more important in the medium consumption. IPTV has the most advanced form of personalized information media. However, IPTV was made by media convergence, which has relation with a variety of interested parties, so there are a few troubles among them in the way of commercializing IPTV. As a matter of fact, although users play a leading role in the IPTV industry, there are still few discussions on the welfare of users. IPTV should be remained the characteristic of the medium of personalized information, and it should include the welfare of users in various fields of media convergence. That is Universal Service. It is necessary to be guaranteed the access right and the variety of contents in using IPTV. Moreover, in terms of telecommunication, IPTV should insure the reasonable fare system as a pay-services. On the basis of the analysis in local and international IPTV circumstances, in terms of content as a medium of personalized information, in terms of fares as a pay-services, and in terms of digital literacy as a new medium of digital access, policies for welfare of users are suggested.

DMB가 출범한지 2007년을 기준으로 3년을 맞이했다. DMB에 대해서는 일반적으로 많이 알려졌으며 새로운 방송 시스템으로 분명 뛰어난 기술이다. 하지만 방송 현업 종사자의 시각에서 볼 때 시청자들의 호응도는 답보상태에 머물고 있다고 판단된다. 방송위원회의 2007년 12월 조사 결과를 보면 DMB는 국민의 60% 이상이 향후에도 구입할 의향이 없다고 조사되었다. 그 이유는 기존방송을 재전송 하고 있는 상황에서 DMB에 맞는 영상 콘텐츠의 부족함으로 볼만한 콘텐츠가 없다는 것과, 작은 화면으로 인한 시각적 불편함 때문이라는 것이다. 또한 방송 초기 유료와 무료 여부에 대한 국가의 정책결정 등의 문제점이 복합적으로 작용하고 있다. 그 외의 불만 사항으로는 서비스 만족도에서 수신가능 지역에 대한 불만이 63.7%로 가장 많았고 배터리 수명의 한계에 대한 불만 54.4%와 단말기 가격에 대한 불만사항 등이 뒤를 이었다. 이런 상황을 종합해 볼 때 DMB는 당초 예상했던 것처럼 황금 알을 낳는 거위가 아니라는 것과, 신규미디어로서 새로운 콘텐츠의 수요창출에 그다지 성공적이지 못 함을 알 수 있다. DMB의 성패는 시청자의 활용도에 따라 판가름 난다고 본다. DMB 기존의 방송을 재전송하고 있다. 하지만 기존의 방송과는 다르게 DMB 자체의 특성에 적합한 콘텐츠로 제작되어야 할 것이다. 이러한 재전송의 문제점을 개선하고 보다 나은 제작방안을 제시하여 시청자들의 DMB 방송 접근 확대화와 활성화가 본 논문의 연구 목적이다.

Recently, software education has been emphasized as a key element of the fourth industrial revolution. Many universities are strengthening the software education for all students according to the needs of the times. The use of online content is an effective way to introduce SW education for all students. However, the provision of uniform online contents has limitations in that it does not consider individual characteristics(major, sw interest, comprehension, interests, etc.) of students. In this study, we propose a recommendation method that utilizes the directional similarity between contents in the boolean view history data environment. We propose a new item-based recommendation formula that uses the confidence value of association rule analysis as the similarity level and apply it to the data of domestic paid contents site. Experimental results show that the recommendation accuracy is improved than when using the traditional collaborative recommendation using cosine or jaccard for similarity measurements.

Recently, the VWORLD was built to ensure competition on the advance of domestic enterprise into foreign markets with rapid expansion of spatial information industry of the world. However, the policy to secure user is insufficient because the VWORLD's service is embryonic stages. Then again, tourist industry is growing rapidly and leading the world economy and number of domestic tourists are also steadily increasing. Although the size was expanded, Korean tourist industry's competition is relatively weak, so some scholars insist that raising the tourist industry's quality. This backgrounds make a study of the tourism information service. So, this paper progressed a study on the development of the tourism information service based on a service science and used VWORLD as a test model. This paper drew the customer's demands on the tourism information service and strategic points of the development from those by using a Quality Function of Deployment of service science's new service development methodologies. After that this study prioritized those strategic points. As a result, 'Face Map' that is a service model was made. Moreover, this study have try to raise the development's effectiveness and efficiency based on service science's a new service development process.
