요즈음 세계적인 유수 통신 사업자들이 새로운 서비스로 가장 큰 관심을 나타내고 있는 것이 IPTV이다. 이는 통신 사업자들이 브로드밴드 IP 네트워크 환경에서 비디오, 음성 및 데이터 정보들을 다양한 형태의 새로운 서비스 패키지로 엮어서 이용자들의 요구에 가장 잘 적응할 수 있게 만든 서비스 모델이 IPTV 서비스이기 때문일 것이다. 그런데 IPTV 서비스가 이용자들에게 고품질의 서비스 및 다양한 부가기능을 갖춘 고기능 부가서비스로 다가갈 뿐만 아니라 효율적인 통신 서비스 시장을 형성하여 나가기 위해서는 표준화의 요구 사항을 만족시켜야 할 것이다. 그러나 IPTV 관련 기술 및 서비스 기능들이 네트워크, 서비스 기능 및 특성, 가입자 액세스 기술, 서비스 품질, 네트워크 특성들이 고려된 종합적인 IPTV 표준화가 이루어지지 않았다. 따라서 각국의 통신 사업자뿐만 아니라 서비스 사업자 및 가입자 시스템 벤더들은 브로드밴드 통신 시장의 수요에 따라 IPTV 서비스의 endto-end 상호운용성(Interoperability)을 제공하기 위한 IPTV 표준화에 경쟁적으로 참여하고 있다. 최근에 ITU-T는 IPTV의 표준화를 위한 포커스 그룹 결성을 위한 준비 모임을 오는 4월 초에 제네바에서 개최하고 7월경에는 공식적으로 표준화 조직으로 결성할 예정이다.

최근 해양레저에 대한 관심이 높아지면서 플레저 보트의 이용자가 점차 늘어나고 있다. 하지만 보트 및 이용자를 수용하기 위한 마리나 시설은 대부분 단순 계류기능으로 영세하며 전국에 총 11개소로 턱없이 부족한 실정이다. 일본의 경우 마리나 및 요트항구는 570개소로 이 중 어항구역에 마리나가 조성된 곳이 27개소가 있다. 기존 어항에 마리나를 조성할 경우 건설 비용감소와 관광수입에 따른 어촌지역 활성화라는 직간접 효과가 있어 한국에서도 일본과 유사한 다기능 어항 개발이 활발히 검토되고 있다. 본 연구에서는 일본의 어항구역 내 플레저 보트 이용 및 관련 시설 조성에 관한 법제도 검토, 현황 및 문제점 분석, 활용사례 검토를 통해 향후 우리나라에서 발생할 수 있는 문제를 미연에 방지하기 위한 시사점을 도출하였다.

최근의 자연 재난의 발생 빈도의 증가는 재난에 대한 정보전달의 중요성이 높아지는 만큼 전달 방법의 중요도도 높아지고 있다. 특히, 2020년의 코로나19(COVID-19)로 인하여 자연 재난에 더해 사회재난에 관한 관심도 증대하고 있으나, 재난정보의 빈도가 매우 높아져, 2000년대 통틀어서 제공된 재난 정보량보다 20년, 21년의 재난 정보량이 더 많아 보인다. 이러한 재난정보의 홍수는 반대급부로 정보의 피로도를 증가시켜 의도적 또는 비의도적 무시 경향을 유발할 수 있다. 이에 본 논문에서는 재난 위험지역을 기반으로 Segment를 생성하고 관리하며, Segment 단위로 재난 위험 메시지를 제공하는 Segment기반 긴급메시지전송 시스템을 연구한다. 목표시스템에서는 재난정보를 실황 정보와 1시간 예측정보를 비교, 위험지역 회피시나리오를 지능화 개선하여 모바일앱 이용자에게 제공함으로써 대피 이동관리와 행동 유도를 이끌어 이용자의 인명피해 저감과 재산손실 감소의 효과를 얻고자 개발하였다.

This study is aimed to draw the meaning and possibility of political participation of the SNS users through a phenomenological analysis of participation and awareness of authentication shot for vote of the users. Especially, the reason for focusing on 'SNS vote authentication shot' is because the creative imagination of the users and the meaning and possibility of collective intelligence are drew while citizens are participating in political activities for themselves. Theory resources are based on technical imagination of Vil$\acute{e}$m Flusser that is concerned with users and political practice in the New Media Era, creative imaginer and discussions of collective intelligence of Pierre L$\acute{e}$vy. Based on these theoretical discussions, it is aimed to select the SNS users experienced in authentication shot for the by-election for mayor of Seoul in 26. Oct. 2011 and to use phenomenological analysis model on materials collected after in-depth interview. The researchers take contextual circumstance into consideration for experiences of study participants sticking to SNS users' opinions and intersubjectivity and approach prejudice of their experiences to untouched structure of phenomenon and meaning. It is because a phenomenological study exploring "the own meaning of 'die Sachen'" is 'strict study' and method focusing on the political participation of SNS users itself.

The purposes of this study are, firstly, to investigate the relationship between the online and mobile game players' psychological aspects (reference group, government regulation, game contents) and their game experience and overindulgence in games and, secondly, to suggest possible ways to reduce overindulgence in games. The implications of this research are as follows; Firstly, families and school authorities should strive to make sports and other pastime activities popular among peer groups rather than allowing online and video games to become only source of popularity among peer groups. Secondly, it is better for families members to establish a set of rules for controlling their children's time spent on online and mobile games rather than entirely forbidding the games. Family members should also strive to have more family conversations and to find a common source of interests. Thirdly, government should strive to develop policy responses to the overindulgence in games based on practical research and analysis. Fourthly, game makers should pay more attention to the components and expressions used in their games so as to draw game players' interests to the story and design of the games. Game makers also need to consider elements in their games that may potentially cause overindulgence in the development stage. Lastly, game players should strive to find new leisure activities besides online and mobile games that they can enjoy and have good experience with.

This study focused on the estimation of econcmic value and the evaluation of attitudes toward plans for the establishment of a walking tour as a public service in the city of Gwacheon. A value analysis based upon 152 questionnaires returned by the residents of Gwacheon and 175 questionnaires from the users of Seoul Race Park in Gwacheon utilized a CVM(Contingent Valuation Method) approach to estimate use value, non-use value, and potential value. The results show that 69.8% of residents and 60.0% of Seoul Race Park users had an interest, 81.6% of residents and 89.7% of Seoul Race Park users agreed to the proposed plan, and 67.8% of residents and 69.7% of Seoul Race Park users expressed a willingness to pay an additional tax or admission fee. The estimated WTP for an additional resident tax per household/year is 11,721 won while it was an additional 750 won per admission for the Seoul Race Park user group. Based on these results, the estimated total economic value of all households/year and the user group over a period of 5 years is 9,997 hundred million won, which was a doubling of the 1.4 in value of total construction costs. The results of this study strongly support the establishment of a walking tour street plan as a public service commodity.

This Study seeks for a plan for promotion of smartification of digital services for improving convenience in use and user services of public libraries in smart digital environment. Thus, in this Study, a survey on awareness of a plan for revitalization of digital data and smart libraries has been conducted for the persons in charge of digital data and librarians from public libraries. The result of this Survey are as follows: first, the introduction of smart libraries was effective by first implementing them in small and medium-sized cities with high interest in in information technology, and spreading them to public libraries in metropolitan cities and special autonomous cities; second, it is analyzed that the essential factor of success in introduction of smart libraries is the contents free from the terminals and the upgrade of computer equipment of users available for the use of these services. Terminals are to be individually utilized by smartphone users but it is necessary for upgrade and introduction of 5G which can secure the mobility of users including open type Wi-Fi; third, it is discovered that the information technology the applicability of which is expected to be easy while introducing smart libraries is RFID, which has been already generalized, and bigtata technology. The introduction of IoT technology in which the stakeholders of public libraries in metropolitan cities and special self-governing cities must be considered first.

As the use of social media has gained mainstream popularity, concerns on the particulars of the users' motivation and method of use is on the rise. Under uses and gratifications approach, this study analyzes the use behaviors in Kakao-story, Facebook, and Twitter, and analyzes the changes in the perception of social support by the users of the media. Data was analyzed from 240 online questionnaire surveys. The study finds that the frequency of use of social media differs depending upon the personality of the users and their purpose of use, both of which also influence their type of use. It also finds that frequent use of social media increased the users' perception of social support, whereas their type of use had no effect with such perception. Communication behavior through social media seem to increase perception of social support.
