Two‐dimensional sectioned images and three‐dimensional surface models for learning the anatomy of the female pelvis

In the Visible Korean project, serially sectioned images of the pelvis were made from a female cadaver. Outlines of significant structures in the sectioned images were drawn and stacked to build surface models. To improve the accessibility and informational content of these data, a five‐step process was designed and implemented. First, 154 pelvic structures were outlined with additional surface reconstruction to prepare the image data. Second, the sectioned and outlined images (in a browsing software) as well as the surface models (in a PDF file) were placed on the Visible Korean homepage in a readily‐accessible format. Third, all image data were visualized with interactive elements to stimulate creative learning. Fourth, two‐dimensional (2D) images and three‐dimensional (3D) models were superimposed on one another to provide context and spatial information for students viewing these data. Fifth, images were designed such that structure names would be shown when the mouse pointer hovered over the 2D images or the 3D models. The state‐of‐the‐art sectioned images, outlined images, and surface models, arranged and systematized as described in this study, will aid students in understanding the anatomy of female pelvis. The graphic data accompanied by corresponding magnetic resonance images and computed tomographs are expected to promote the production of 3D simulators for clinical practice.

Diffusion of the New Video Delivery Technology: Is There Redlining in the Internet Protocol TV Service Market?

This study examines the current status of the entry behavior of Internet Protocol TV (IPTV) into the video programming service market, with a particular focus on income redlining and local competition. Analyzing previously unavailable data on telecommunication companies' introduction of IPTV services into Indiana, this study found that although IPTV's entry into the state increased the local competition between cable and IPTV, this local competition was mostly confined to higher income areas due to the income redlining tendency associated with IPTV's entry. These empirical findings raise the issue of the recent deregulation policy reforming cable franchising rules, whose goal was to promote local competition but which might insufficiently reflect the public interest, especially for low-income households.     

An Application of the Analytic Network Process to the Advertising Media Budget Allocation Decision

This study developed and tested a comprehensive model for media selection and budget allocation using the analytic network process (ANP; Saaty, 1996). ANP can be used to solve complex decision-making problems by integrating different measures (both qualitative/intangible and quantitative/tangible) into a single overall score for ranking decision alternatives. The resultant model may be used by expert or novice media planners with equal effectiveness. This study demonstrated how this model may be used to allocate media dollars for 2 industries: airlines and financial services.     

The Impact of the Korean Government's Privatization of Korea Telecom (KT) on the Korean Telecommunications Industry: KT's Financial and Operating Performance

Abstract

This article examines the relation between the privatization of state-owned enterprises and the changes in their financial and operating performance through the case study of Korea Telecom (KT), which is the biggest telecommunications (telecom) company in Korea. The Korean government completed the privatization of KT in May 2002, arguing that it would help KT to improve its financial and operating performance, as well as contribute to the development of the telecom industry. This article presents the changes in KT's revenues, assets, net income margins, return on assets, real sales per employee, investments, and dividends to evaluate its financial and operating performance, as well as the impact of the privatization of KT on the Korean telecom industry over the pre- and post-privatization windows.     

The cultural politics of national testing and test result release policy in South Korea: a critical discourse analysis

This paper examines the ideological construction of educational discourses embedded within the South Korean print media. Significantly, these discourses have recently promoted the resurrection of a sweeping national testing and test results release policy. Through careful examination of the “test plus release” policy, the authors show how the government has achieved hegemonic power by shaping public opinion through the national testing contexts. Drawing on a critical discourse analysis of educational policy texts from the government and top 10 print media sources, this paper analyses how discourses on “accountability”, “the right to know” and “the fairness of the tests” have been produced, reproduced and recontextualized to favour particular perspectives. The authors also examine how government and influential print media discourses interact with political and cultural factors such as “acclaiming the evaluative state”, “education fever” and “meritocratic beliefs” to achieve public consent for the new “test plus release” policy.     

Is the United States losing its status as a reference point for educational policy in the age of global comparison? The case of South Korea

This paper seeks to contribute to recent comparative discussions about the shift of traditional referential points as a result of new global governance by the OECD through PISA. In doing so, the authors investigate whether the lower PISA rankings of the US have resulted in the shifting of its referential status in South Korea. For the purposes of analysis, media representation of US education in South Korea is analysed by using two disparate newspapers from two time periods: three years before the first PISA release in 2001 and three years after 2009. This paper uses media discourses as primary data, but it also considers other complementary data such as policy documents and government policy statements on education. Recently, global governance through comparative data has become more significant, but the results of this study suggest that one should be careful about oversimplification. The results of this study imply that the pattern of external referencing in media representation hinges on historical, political, and cultural experiences rather than purely evidence-based discourses, at least in the case of South Korea.     

Diversity-related research reported in high-impact library and information science journal literature: A content analysis

This study reports a content analysis of the frequency distribution of diversity-related research in four high-impact Library and Information Science (LIS) journals published between 1995 and 2014. High-impact journals (with high rankings and impact factors) were chosen because empirically based articles from them are more likely to be able to influence future research direction. The journals chosen were published articles quarterly or bi-monthly, with an average of 5–6 articles per issue. A total of 1766 research articles were collected, with 28.71% determined to be related to diversity. Results show an increasing interest in diversity-related research in the LIS field, with a dramatic increase between 2010 and 2014. The majority of diversity-related research focuses on age, gender and ethnicity. Only a small portion of research discusses issues concerning specific populations and emphasizes diversity-related theoretical concepts. More efforts are needed to highlight the link in order to contribute to the diversity and inclusion agenda in LIS.     

The critical loading for lateral buckling of continuous welded rail

INTRODUCTION The conventional design of rails uses steel clipboards and bolts to link rails, and avoids bucklingcaused by thermal expansion effect by mountingexpansion joints to solve axial restraint generated byseasonal or day-and-night temperature changes. Butthe discontinuity at the rail joints brings discomfortand noise to passengers when the train has suddenlystops or starts, during which train speed cannot beeffectively increased, rails are more easily damaged,and the cost of mainte…     

The effectiveness of a marketing virtual reality learning simulation: A quantitative survey with psychophysiological measures

Virtual reality (VR) technology has been shown to be a promising teaching method in STEM subjects. Extending these findings, the current study is the first to develop and examine the feasibility of using a VR simulation in marketing (ie, a non-STEM subject). Specifically, the levels of immersion and three learning outcomes (learning attitude, enjoyment and performance) were compared between the marketing students who learned the same content through a VR simulation prototype versus a traditional static video presentation. Learning enjoyment was measured using facial electromyography, which served as a more objective measures for the feeling of enjoyment. Compared to the video condition, the results showed that VR resulted in a higher experience of immersion, learning attitude and learning enjoyment. Furthermore, immersion was found to fully mediate the positive effects of the VR simulation on learning attitude, but not enjoyment. Surprisingly, students in the video condition performed better on the knowledge-based test than those in the VR condition. The current study suggests that the current prototype of the VR simulations should be used as supplementary resource to increase the learning attitude and enjoyment, but not as a main teaching material to enhance knowledge-based performance in the marketing discipline.     

Method of effective evaluation for examination of chloride ion in concrete

INTRODUCTION For some unknown reasons, perhaps caused bysalt, chlorine ions usually exist in reinforced concreteconsisting of cement, water, aggregate and additionalmaterials, and steel bars. In the presence of water, thechlorine ion reacts with iron existing in concrete andsteel bars to form Fe(OH)2 and FeCl2. The chemicalreactions seriously corrodes the surface of steel barsand damage the concrete, causing gradual decrease ofthe concrete compression and increase of its porosity,…
