This article presents the Internet Connectedness Index (ICI), a measure for monitoring long-term inequalities in the quality of Internet connections among users, especially in terms of whether Internet connections will enhance the chances of people's upward mobility. This index is preferable to more established digital divide measures (e.g., gadgetry ownership or time online) for research on how the Internet is being incorporated into a world of structural inequalities. The ICI utilizes conventional time, history, and context measures, but goes beyond them to capture the scope and centrality of Internet incorporation into the everyday lives of diverse social groups. The validity and robustness of ICI vis-á-vis conventional ownership and time online measures are demonstrated in this article. In addition, the authors discuss theoretical, methodological, and policy implications based on the results. The analytical data are drawn from the Communication Technology and Community Program's Metamorphosis Project, an inquiry into the communication infrastructures of seven ethnically marked residential areas in Los Angeles.

BackgroundThe Internet has increasingly become a popular source of health information by connecting individuals with health content, experts, and support. More and more, individuals turn to social media and Internet sites to share health information and experiences. Although online health information seeking occurs worldwide, limited empirical studies exist examining cross-cultural differences in perceptions about user-generated, experience-based information compared to expertise-based information sources.ObjectiveTo investigate if cultural variations exist in patterns of online health information seeking, specifically in perceptions of online health information sources. It was hypothesized that Koreans and Hongkongers, compared to Americans, would be more likely to trust and use experience-based knowledge shared in social Internet sites, such as social media and online support groups. Conversely, Americans, compared to Koreans and Hongkongers, would value expertise-based knowledge prepared and approved by doctors or professional health providers more.MethodsSurvey questionnaires were developed in English first and then translated into Korean and Chinese. The back-translation method ensured the standardization of questions. Surveys were administered using a standardized recruitment strategy and data collection methods.ResultsA total of 826 participants living in metropolitan areas from the United States (n=301), Korea (n=179), and Hong Kong (n=337) participated in the study. We found significant cultural differences in information processing preferences for online health information. A planned contrast test revealed that Koreans and Hongkongers showed more trust in experience-based health information sources (blogs: t 451.50=11.21, P<.001; online support group: t 455.71=9.30, P<.001; social networking sites [SNS]: t 466.75=11.36, P<.001) and also reported using blogs (t 515.31=6.67, P<.001) and SNS (t 529.22=4.51, P<.001) more frequently than Americans. Americans showed a stronger preference for using expertise-based information sources (eg, WebMD and CDC) compared to Koreans and Hongkongers (t 360.02=3.01, P=.003). Trust in expertise-based information sources was universal, demonstrating no cultural differences (Brown-Forsythe F 2,654=1.82, P=.16). Culture also contributed significantly to differences in searching information on behalf of family members (t 480.38=5.99, P<.001) as well as to the goals of information searching.ConclusionsThis research found significant cultural differences in information processing preferences for online health information. Further discussion is included regarding effective communication strategies in providing quality health information.

This article examines the influence of the social environment on adolescents' connectedness to the internet in East Asia, one of the most wired regions in the world. Connectedness is a qualitative conceptualization of an individual's relationship with the internet, taking into consideration the breadth, depth, and the importance of individuals' internet experience. This study seeks to situate adolescents' internet connectedness in three spheres of social environment: (1) the general social support measured by how easy it is to get help when adolescents encounter problems in using the internet; (2) the parents, where we examine parents' socioeconomic status and their internet use; and (3) the peer group, where we look into the new media & society

The purposes of the current study are (1) to conceptualize and test a social networking service (SNS) dependency measure and (2) to propose and test a general model of the effect of SNS dependency on online and offline interpersonal storytelling. This study is theoretically guided by media system dependency theory and communication infrastructure theory. Computer-assisted personal interviews (CAPI) were conducted with 477 SNS users aged 19–59 in Seoul in October of 2012. Confirmatory factor analyses results showed that our SNS dependency measure was valid and reliable. The results also confirmed that SNS dependency had direct effects on individual users’ levels of engagement with interactive activities on SNSs and indirect effects on offline interpersonal storytelling.

Autoimmune hemolytic anemia associated with an ovarian teratoma is a very rare disease. However, treating teratoma is the only method to cure the hemolytic anemia, so it is necessary to include ovarian teratoma in the differential diagnosis of autoimmune hemolytic anemia. We report herein on a case of a young adult patient who had severe autoimmune hemolytic anemia that was induced by an ovarian teratoma. A 25-yr-old woman complained of general weakness and dizziness for 1 week. The hemoglobin level was 4.2 g/dL, and the direct and indirect antiglobulin tests were all positive. The abdominal computed tomography scan revealed a huge left ovarian mass, and this indicated a teratoma. She was refractory to corticosteroid therapy; however, after surgical resection of the ovarian mass, the hemoglobin level and the reticulocyte count were gradually normalized. The mass was well encapsulated and contained hair and teeth. She was diagnosed as having autoimmune hemolytic anemia associated with an ovarian teratoma. To the best of our knowledge, this is the first such a case to be reported in Korea.

Based on survey data gathered before and after September 11, 2001 (‘9/11’), this study examines the relationship between ‘internet connectedness’ and communicative actions after September 11 2001. The study found that: (1) people heightened their dependency relations with traditional mass media after September 11, regardless of whether or not they had an internet connection; (2) ‘internet high-connectors’ intensified their internet connections, while ‘internet low-connectors’ decreased the intensity of their internet connections; and (3) internet high-connectors participated in a broader range of civic activities in response to September 11 than did internet low-and non-connectors.
