지상파 UHD 방송은 2017년 세계 최초로 본방송이 시작되었고 2018년 평창 올림픽과 러시아 월드컵을 지상파 UHD 방송으로 중계하면서 성장해 왔다. 그런데 최근 급변하는 미디어 기술과 코로나 19 팬데믹 이후 미디어 시장이 요동치며 미디어 이용 플랫폼과 콘텐츠 그리고 미디어 이용 기기별 사용 시간에도 많은 변화가 생기고 있다. 이에 따라 지난 2017년 본 방송 이후 지상파 UHD 방송에 대한 시청자들의 이용 실태 및 인식 변화에 대한 조사의 필요성이 대두하게 됐다. UHD KOREA와 KBS 공영미디어 연구소는 UHD 방송에 대한 인지도와 시청의향, TV 크기의 변화, TV와 인터넷 연결 여부 등 미디어 환경변화에 따른 시청자의 미디어 이용 형태를 공동으로 조사했다. 그리고 지상파 UHD 방송의 추가 서비스의 선호도와 선호 콘텐츠, OTT 이용 여부 등에 대하여도 분석했다. 지상파 UHD 방송은 고화질, 다채널, 모바일, 재난방송, 양방향 서비스 등 ATSC 3.0 기술을 기반으로 다양한 최신 서비스를 제공하는 것이 가능하다. 이러한 조사 결과는 향후 지상파 UHD 방송 및 미디어 정책의 수립과 추진의 기초 자료로 활용될 것이다.

There is a need to provide appropriate transportation safety services to foreigners residing in Korea. The main purpose of this study is to enhance transportation safety services for foreigners. In order to identify the risk of traffic accidents, analysis of traffic accidents was conducted using a survey of foreigner travel behavior. According to the results of this model, the study suggests directions to achieve improvement of traffic safety services for foreigners who are unfamiliar with the transportation systems. The study results show that the risk of traffic accidents is influenced by two factors: comprehension of transport geography and of traffic laws. Necessity of policy is influenced by two factors: comprehension of transportation system and the risk of traffic accidents. Intention of using policy is influenced by two factors: the risk of traffic accidents and necessity of policy. Effect of policy is affected by the intention of using policy. The results also demonstrate that the traffic safety services for foreigner can be described as endogenous variables which are approximately 88% of the traffic safety education, 85% of the demanded multicultural district, and 75% of the portal traffic information. Compared with existing research, this study provides a systematic methodology to evaluate effects and the order of priority in establishing traffic safety policies for foreigners.

In order to support various QoS, IETF has proposed the Differentiated Services Model which provides discrimination service according to t the user’s requirements and payment intention intention for each traffic characteristic. This model is an excellent mechanism, which is not too c complicated in terms of the management for service and network model. Also, it has scalability that satisfies the requirement of Differentiated Services. In this paper, We define the Differentiated Services Model using feedback control, propose its control procedure, and analyze its p performance. In conventional model, non-adaptive traffic, such as UDP traffic, is more occupied the network resource than adaptive traffic, such a as TCP traffic. On the other hand, the Differentiated Services Model using feedback control fairly utlizes the network resources and even p prevents congestion occurrence due to its ability of congestion expectation.

This study investigates the recommendation for tax accounting services used in many companies. In particular, it aims to create guidelines for small businesses with fewer than 100 employees, which are relatively difficult to manage in terms of cost or time. We surveyed 100 corporate officials on basic business information, such as the number of employees, job titles, and business type, as well as the type of tax accounting service, the recommended score for the service, the reason for the score, and other opinions related to tax accounting services. In particular, the recommendation score seeks to obtain more effective results by using the Net Promoter Score method, which is known to be more effective in understanding customer opinions than general customer satisfaction surveys. The survey revealed a Net Promoter Score for a recommendation of -33 points, lower than the general Net Promoter Score. It also indicated that tax accounting services need improvement. Specifically, the opinions of the respondents who gave a non-recommendation score were as follows: "Not inconvenient or comfortable," "It was just okay," "I don't know if it would be helpful," and "There is no differentiation and there are no special alternatives." We concluded that an improved service for raising recommendation scores was necessary. This survey focused on recommendations for companies with fewer than 100 employees; future studies should incorporate larger companies and more variables.

인터넷을 통해 물품 / 서비스 / 정보를 거래하는 것이 이제는 더 이상 새로운 현상이 아니다. 즉, 정보활용기술의 급진적 발전으로 인터넷을 통한 상거래는 시간과 장소 그리고 취급 품목의 제한 없이 필요한 거래를 할 수 있게 되었다. 그러나, 인터넷 쇼핑은 컴퓨터를 물리적으로 인터넷에 접속되어 있어야 만이 필요한 내용을 검색하고 주문하여 구매를 할 수 있어 21 세기를 바쁘게 살아가는, 많은 이동이 수반되는 사람들에게는 물리적 인터넷 접속은 하나의 큰 제한이 되고 있다. 따라서 소비자들을 이러한 한계를 초월할 수 있는 무선으로 인터넷에 연결하여 이동 중에도 핸드폰을 통해 쉽고 간편하게 그리고 더욱 편리하게 상거래 행위를 유도하는 것은 자연스러운 현상이라고 할 수 있다. 이 연구는 이러한 요구에 부응하기 위해 일본과 한국에서 이동전화를 이용하는 사람들의 특정을 살펴보고 1) 이동 전화사용의 주목적, 2) 이동전화가 편리한 이유, 3) 이동전화 형태의 선호도, 4) 이동전화 사용의 심리적 안정, 5) 이동전화 사용의 문제점 등에 대한 내용을 설문조사를 통해 조사하여 추후 이동전화를 통해 물품 / 서비스 / 정보를 구입할 의향에 어떠한 영향을 미치는 가를 조사하는 것이다.

The purpose of this study is to provide policy implications for vitalizing u-health services. We carried out survey of 500 consumers and indepth interview with various experts. Both experts and consumers believe that u-health services will become prevalent in the longrun, although there exist obstacles against vitalization of u-health services. To vitalize u-health service, the Korean government should raise reliability and recognition of u-health service for consumers. Furthermore, law and institution regarding u-health services should be improved to give enough incentives for u-health suppliers and consumers.
