IPTV는 기술적으로 TV에 PC적 기능이 더해지고 인터넷 프로토콜(IP)을 통해 인터넷과 연결되는 서비스로, 국내 초고속인터넷의 속도가 VDSL, 광랜과 같은 서비스의 등장으로 최대 100Mbps에 이르러 동영상 콘텐츠의 실시간 스트리밍 서비스가 가능한 환경이 구현되었다. IPTV 도입을 통해 산사건 방송, VOD 등의 기본적인 서비스뿐만 아니라, 양방향 광고, IPTV 민원발급 및 IPTV 공공서비스 제공 등 다양한 응용서비스의 개발 및 활성화를 기대하였다. 또한 IPTV를 통해 유료방송의 경쟁을 촉진시키고 케이블TV의 디지털 전환을 촉진시킴으로써 시청자들의 복지를 향상시킨다는 취지도 함께 있었다. 정량적으로는 IPTV가입자가 2012년에 이르러 보수적으로 290만가구, 낙관적으로는 450만 가구에 이를 것으로 예상하였으며, 관련 시장규모도 동년도에 약 7,515억원에 이를 것으로 전망하였다. 하지만, 2011년 말이 이미 450만 가입자를 돌파하고 2012년 8월 500만 가입자를 유치하면서 IPTV 서비스는 본격적인 mass market을 형성해 나가고 있다. IPTV 시장이 확대해 나가면서 유료방송 가입가구 수도 증가하였는데, 도입당시인 2008년 말 1,740만 가구가 유료방송에 가입하여 104%의 보급률을 보였으나 2011년 6월말 현재 가구수 대비 유료방송 가입자구수는 127%로 증가하였다. 이렇게 IPTV서비스 시장이 확대되고는 있으나, 정부의 신규 서비스에 대한 과도한 요금규제, IPTV와 경쟁하는 케이블방송사(SO) 계열의 콘텐츠 사업자(CP)들의 방송채널 공급거절 및 지상파 방송사의 과도한 재전송 대가, 전국 권역사업자인 IPTV에 대한 권역별 가입자점유율 규제, IPTV의 차별성으로 내세웠던 T-Commerce 및 양방향 광고에 대한 규제는 앞으로 개선해 내가야할 과제이다. 이에 본고는 IPTV의 시장성과를 조망하고, 시장의 지속성장을 위해 필요한 제도개선 방향을 살펴보았다.

As non-face-to-face contact was activated due to the progress of the 4th Industrial Revolution and COVID-19, the government's civil service was also rapidly reflecting this phenomenon. However, there were cases in which it was quite burdensome and rather uncomfortable for the elderly who were relatively alienated from the digital culture. Therefore, in this study, we tried to empirically analyze the factors that affect the use of government 24(a government civil integration service) by the elderly. For this purpose, the characteristics of the elderly and the characteristics of services were paid attention. As the characteristic factors of the elderly, cognitive characteristics, psychological characteristics, and physical characteristics were derived, and as service characteristics, usefulness, ease of use, security, and government support were derived when using government 24. The effect of these factors on the intention to use Government 24 was empirically analyzed. For empirical analysis, a survey was conducted targeting the elderly in their 60s and older, and 250 valid sample were used for analysis. The analysis results were as follows. Among the characteristics of the elderly, cognitive characteristics, psychological characteristics, and physical characteristics were all found to had a significant negative (-) effect on the intention to use Government 24. On the other hand, usefulness, ease of use, and government support were found to had a significant positive (+) effect on the intention to use government 24. On the other hand, security was not tested for a significant relationship with government 24 use intention. Among the variables that have a significant impact, the psychological characteristics of the elderly had the greatest impact on the intention to use Government 24. Usefulness, cognitive characteristics, physical characteristics, ease of use, and government support were in order. The fact that this study conducted an empirical analysis by combining the characteristics of the elderly and the characteristics of services was meaningful at the academic level. In addition, considering that psychological characteristics appeared to be the most important factor, it seemed necessary to consider these points to promote the use of Government 24 by the elderly.

It may not be strange to anticipate that the forth-coming epoch of electronic government would bring us lots of convenience on account of ubiquitous environment with mobile devices. Such environment enables us to access the up-to-date information anytime and also a worker to carry out administration services to perform one's line of duty at anytime with electronic, handy devices such as PDA. What we now recognize from the field of electronic traffic administration services is that the office work flow as well as the public services has been remarkably improved by using of not only text but video and image information under the distributed, mobile environment. One of key requirements of this kinds of services is the feature of exchanging various information among multiple information publishers and subscribers. We call this feature Messaging Services generally The study in this paper focuses on the architecture design of the Messaging Engine software, complying with the pattern-oriented software architecture design methodology. And our contribution also goes to the discovery of three architecture patterns found in the design process and the efficient multi-threading architecture compared to one of the Messaging Engine solutions.

The aging population and the advancement of science and technology are transforming the healthcare industry to focus on health management for the prevention of diseases. The U-health and remote healthcare services have not yet achieved the social agreement in the nation; however, these have been extensively used in the global scale. The innovation of user experience through cognitive computing are expected to increase the health effects of consumers, by converging with healthcare information services. This study suggests the conceptual model of healthcare information service converged with cognitive computing. Then, the acceptance factors for consumers have been investigated. For this purpose, reliability and validity analysis have been conducted using an online survey. The path analysis was performed to verify the hypotheses and moderating effect based upon the gender, by using structural equation modeling.

Today's information services in most archival institutions implement the same administrative procedures for general users and academic researchers, leading to issues hindering the latter's research activities. As such, this study presents a direction for the effective provision of information services by investigating and analyzing information sources mainly used by academic researchers, who are one of the major user groups; researchers' use behaviors in archival institutions; and experiences and perceptions on the such institutions' information services. In particular, surveys and interviews were conducted, and 75 questionnaire responses and 8 interview results were analyzed. The results of the analysis were summarized into the researcher's background information, information sources used, behaviors in using archival institutions' services, information service utilization, improvement requirements, and desired services. Through the results' implications, plans for the provision of information services by archival institutions were proposed based on the researchers' needs and preferences.

Implementation of patient feedback is considered as a critical part of effective and efficient management. This study is a retrospective survey after to ensure the medical convergence analysis of contents on customer dissatisfaction using medical services. The data were collected from dissatisfaction 319 case at a affiliated hospital. The result indicate that a repeat visit than the initial visit, outpatients were more dissatisfied than the inpatients. The type of dissatisfaction were more dissatisfied of the in communication and explanation of medical service, nursing service and procedure of administrative services. In the classification of disease the percentages of dissatisfaction in the digestive system and neoplasm were high in both groups(p<0.05). Based on the study to improve the quality of medical service. Prevent the recurrence of dissatisfaction and to establish a customer-oriented business strategy. Characterized by dissatisfaction factors and contents of each patient and should be structured to specific disease types of services through continuous medical convergence research.

Recently, users' complaints on drinking water quality are increasing according to emerging interest in the drinking water service issues such as pipe aging and various water quality accidents. In the case of drinking water quality complaints, not only the water pollution but also the inconvenience on the chlorine residual for disinfection are included, thus various efforts, such as rechlorination treatment, are being attempted in order to keep the chlorine concentration supplied evenly. In this research, for a more accurate water quality simulation of water distribution network, the water quality reaction coefficients were estimated, and an optimization method of chlorination/ rechlorination scheduling was proposed consideirng satisfaction of water quality standards and chlorine residual equalization. The proposed method was applied to a large-scale real water network, and various chlorination schemes were comparatively analyzed through the grid search algorithm and optimized based on the suitability and uniformity of supplied chlorine residual concentration.
