This study analyzed what consumer characteristics affect the experience of using overseas direct purchase at a time when the overseas direct purchase market is rapidly increasing and consumers' interest in overseas direct purchase is increasing accordingly. For the study, personal data from the 2022 Korea Media Panel Survey were used, and data from 6,734 people who responded "yes" or "no" to whether or not to use overseas direct purchase among 9,941 total respondents were used for analysis. In addition, three variables (demographic, media utilization status, values and lifestyle) were selected among the items of the Korea Media Panel Survey. First, general characteristics were analyzed fo 6,734 people, then, Chi-square test and t-test were performed for comparative analysis between each variable according to the use of overseas direct purchase. Finally, logistic regression analysis was performed to identify the factors affecting overseas direct purchase. As a result of the analysis, 4 out of 5 demographic variables, 2 out of 3 media utilization variables, and 3 out of 7 values and lifestyle variables were derived as decisive factors for using overseas direct purchase. These results can be used to establish marketing strategies that can increase the use of consumers through domestic shopping malls, such as providing differentiated services for the sale of overseas direct shopping products on domestic shopping sites.

This study attempts to introduce the methodology for accounting real-time population distribution in the urban areas. For the purpose, we utilize the media user's time-space information from the media users' media diaries in the media panel survey databases. We analyze the space-time population rate for each activity space related with everyday urban lifes. Seoul has been selected as a case study area, since space-time information are relatively rich there, and thus the comparisons are available. The space-time population rates have been verified by the comparative analysis with the T-card results. We propose a real time population measurement method by combination of the space-time population rate with geographical data. The real time population of each activity space at each dong in Seoul has been calculated by multiplying the space-time population rates to the numbers of employer of three categories of activity spaces(residential, working, and commercial). By utilizing GIS, we visualize the results of two time points (3AM and 3PM) and then analyze the spacio-temporal characteristics of real time population distribution in Seoul. The Day time population distribution pattern shows strong relationships with the distribution of business and commercial activities, while the night time population distribution pattern can be explained by resident population distribution almost perfectly.

This research observes how an adolescent's usage of social network services is related with media use time, and also tries to verify how a parent's participation in acting to limit usage time serves as a mediating effect. For this analysis, data from The Korean Information Society Development Institute [Korea Media Panel Research] was used, being a survey conducted on 1,572 students from primary to secondary and high schools nationwide. The subjects' gender in the final analysis was 818 male students and 754 female students. In addition, primary school students consisted of 672 individuals, 416 were from secondary and 484 from high schools. To verify the appropriateness of the model proposed in this research, analyzed through the structural equation, using social network services(SNS) was not shown to have an effect on media usage time. However, there was an indirect effect from the use of alternative activities. In addition, the parent's limitation of usage showed no effect on media use time. This research attempts to identify the reasons why parents' limiting the usage time, along with alternative activities, do not have any significant effect in reducing media usage time in this era of smart media evolution. Further, this research hopes to suggest meaningful and political implications for the nation and society to understand and resolve media addiction.

This study analyses the business performance according to the business diversification of Korean mass media enterprises from year 2003 to 2006. The conclusions drawn which could be divided into five main parts are the followings: First, newspaper companies pursue unrelated diversification in various industrial areas, in order to gain maximum profit while broadcasting companies exert themselves to provide better service by diversifying the major contents. Second, overall the interviewed companies display a constant decline in profit gained from their major business area thus establishing strategies to broaden their focus on diversification of any sort. Third, the researcher completed group analysis in regard of diversification measure resulting in division of three groups. The group which had the most immense diversification range gained the highest ROE, the lowest ROE volatility, and lesser probability of risk taking. The analysis adresses the companies broadening their business areas by researching and focusing on diversification are relatively stable in terms of the profit they gain. Fourth, the middle level group in terms of sales scale, debts, enterprise history, major share rate and high ROE group carry out diversification progressively. The sales scale affects positively to diversification, while the major share rate affects negatively to diversification. Fifth, in accordance to the research, diversification overall contributes to obtainance of successful outcome. Since there was not an immense amount of studies to be referred in the media area, the researcher interviewed and did panel discussion with numerous strategists and managers who are in charge of diversification of media companies. However, collection of only 4 years of data limits the research to be considered to be a generalized study, and does not reflect time gap between business diversification and business performance. Development is required in future studies to be established regarding the media companies' specificity different to other industries, classified the media companies into media types, and consider the time gap in the diversification activities and business performance.

3차원 비디오는 차세대 정보 통신 서비스 분야의 하나로, 사용자에게 시각적으로 고차원적인 서비스를 제공하는 것을 목적으로 한다. 이 가운데 다시점 비디오는 같은 시간, 여러 시점에서 영상 정보를 획득하여 사용자에게 원하는 시점의 영상 정보를 제공하는 3차원 비디오이며, 현재 방송 관련 연구 기관에서 차세대 실감방송 멀티미디어 서비스 개발을 목적으로 하는 연구가 활발히 진행되고 있다. 최근 MPEG 표준화 그룹에서는 다시점 비디오 부호화 (multi-view video coding, MVC) 방법에 관한 표준화 작업이 진행 중이며, 최신 비디오 압축 표준인 H.264를 이용한 여러 가지 방법들이 제안되었다. 현재 MVC 표준화 작업의 평가 기준이 되는 방법은 각 시점을 H.264로 부호화하는 방법인데, 이는 다시점 비디오 영상의 중요한 특성인 인접시점들 사이의 공간적 상관도를 전혀 고려하지 않았다. 본 논문에서는 시점 보간법을 이용하여 얻어진 중간 영상과 원영상과의 차분 영상을 부호화하는 알고리즘을 제안하고자 한다. 여기서 시점 보간법이란 좌우 두 시점 영상으로부터 변이값을 얻은 다음, 이를 이용하여 중간 시점 영상을 합성하는 방법을 말한다. 예를 들면,다시점 비디오의 홀수 번째 시점의 영상은 기존의 방법을 따르고, 짝수 번째 시점의 영상은 이미 부호화된 홀수 번째 시점의 영상을 이용하여 보간적으로 예측하여 원래 영상과 차분 영상을 구하여 부호화한다. 차분 영상은 영상의 복잡도가 많이 감소되어 원영상에 비해 보다 나은 부호화 효율을 보인다. 그러나 합성 영상이 각 장면마다 독립적으로 생성되므로 원영상에 비해 차분 영상의 시간적인 상관도가 줄어들어 I장면의 경우 부호화 효율이 크게 향상되었으나, 시간적인 상관도를 이용하는 P장면과 B장면에서는 오히려 좋지 않은 결과를 보였다. 통계는 전 국민에 대한 패널자료이기 때문에 통계적 활용의 범위가 방대하다. 특히 개인, 가구, 사업체 등 사회 활동의 주체들이 어떻게 변화하는지를 추적할 수 있는 자료를 생산함으로써 다양한 인과적 통계분석을 할 수 있다. 행정자료를 활용한 인구센서스의 이러한 특징은 국가의 교육정책, 노동정책, 복지정책 등 다양한 정책을 정확한 자료를 근거로 수립할 수 있는 기반을 제공한다(Gaasemyr, 1999). 이와 더불어 행정자료 기반의 인구센서스는 비용이 적게 드는 장점이 있다. 예를 들어 덴마크나 핀란드에서는 조사로 자료를 생산하던 때의 1/20 정도 비용으로 행정자료로 인구센서스의 모든 자료를 생산하고 있다. 특히, 최근 모든 행정자료들이 정보통신기술에 의해 데이터베이스 형태로 바뀌고, 인터넷을 근간으로 한 컴퓨터네트워크가 발달함에 따라 각 부처별로 행정을 위해 축적한 자료를 정보통신기술로 연계${cdot}$통합하면 막대한 조사비용을 들이지 않더라도 인구센서스자료를 적은 비용으로 생산할 수 있는 근간이 마련되었다. 이렇듯 행정자료 기반의 인구센서스가 많은 장점을 가졌지만, 그렇다고 모든 국가가 당장 행정자료로 인구센서스를 대체할 수 있는 것은 아니다. 행정자료로 인구센서스통계를 생산하기 위해서는 각 행정부서별로 사용하는 행정자료들을 연계${cdot}$통합할 수 있도록 국가사회전반에 걸쳐 행정 체제가 갖추어져야 하기 때문이다. 특히 모든 국민 개개인에 관한 기본정보, 개인들이 거주하며 생활하는 단위인 개별 주거단위에 관한 정보가 행정부에 등록되어 있고, 잘 정비되어 있어야 하며, 정보의 형태 또한 서로 연계가 가능하도록 표준화되어있어야 한다. 이와 더불어, 현재 인구센서스에서 표본조사를 통해 부가적으로 생산하는 경제활동통계를 생산하기 위해서는 개인이

The OTT service in Korea is not as popular as that in the U. S. This study argues that one of the major reasons of poor performance of OTT in Korea is that the OTT service providers did not acquire attracting contents, thus failing to appeal to Korean users. The other reason is Korean users are not willing to use OTT services because of high telecommunications fees to use OTT services. That is why most OTT users are using OTT services in WiFi zones, such as house, workplace, or school. This study investigated the popular OTT contents in recent three years, and how these popular OTT contents are provided in OTT service platforms, and how these contents are used in different places. The results of this study may provide several implications for OTT service providers' strategies in the future, and propose policy implications for the development of OTT services in Korea.

This study explores how the digital divide caused by personal SES(Socio-Economic Status) eventually affect personal life satisfaction. The study also investigates the differences between living in urban and rural areas, as well as the differences among generations, with respect to the digital divide and personal life satisfaction. Based on the Korean Media Panel data produced by KISDI, this study used 9,647 national samples to obtain variables such as digital divide, and life satisfaction. Results show that personal SES is a key factor that significantly influences digital divide and life satisfaction in various degrees. Also, the study finds that the degree of the digital divide have an effect on people's life satisfaction. The findings imply that people living in urban areas are more highly used to digital media than those in rural areas regardless of their SES. The study has an implication, in terms of digital equity among generations as well as urban and rural residents.
