The advent of big data brings the opportunity to answer many open scientic questions but also presents some interesting challenges. Main features of contemporary datasets are the high dimensionality and massive sample size. In this paper, we give an overview of major challenges caused by these two features: (1) noise accumulation and spurious correlations in high dimensional data; (ii) computational scalability for massive data. We also provide applications of big data in various fields including forecast of disasters, digital humanities and sabermetrics.

It is hard to imagine teaching statistics without the help of technology. Technology is changing the way in which the content of introductory statistics is taught and the forms of textbook used. Almost all students carry mobile devices all the time that allows them to learn anytime and anywhere if we provide them with statistical electronic textbook. The use of smartphones for asking questions and finding answers in class, it can encourage students to engage more in lectures. This paper analyzes the data obtained using e-textbook in traditional classroom and discusses the future research direction of e-textbooks.

Background & objective: The Korean government has expanded its benefit coverage to enhance patients' access to orphan drugs and cancer medicines. However, the number of new drugs whose indications were not applied to reimbursement in health insurance was increased. This study aimed to understand the perspectives of experts and various stakeholders on the introduction of a new funding program for cancer treatment and orphan drugs. Methods: We conducted email surveys comprising 19 questions, from September 9 to 26, 2016. We distributed questionnaires to members of the Pharmaceutical Benefit Appraisal Committee and Cancer Assessment Committee. We also conducted a qualitative study through group interviews with stakeholders, including pharmaceutical companies and some patient groups for diseases. Results: A total of 35 survey respondents recommended the introduction of a funding program for orphan drugs, whereas 66% recommended the launch of funding for anticancer drugs. In addition, most pharmaceutical companies and patient groups recommended the introduction of new funding programs targeting patients with cancer and rare diseases. However, some participants asserted that it would be more appropriate to modify the existing reimbursement scheme than launch new funding. Conclusion: This study concluded that introducing new funding needs a social consensus to relieve financial hardships at the patient level.

The analysis and examination of this study are focussed on the external deconstruction trend expressed in the works of Jean Paul Gaultier. The external deconstruction is a way of expression faithful to the literal meaning of 'deconstruction' and is the applied case of exposure, destruction, poverty, and decomposition as they are. The method and scope of this study are from 1980's to present, and the followings are the results of this examination focussed on the various literature of philosophy, aesthetics and literary criticism, and the domestic and foreign fashion journals. The exposure phenomena through the deconstruction expressed repeatedly in the works of Gaultier deconstructed the fixed idea of 'the inner wear should be worn inside the outer wear' and at the same time denied the dichotomical interpretation of the exposure and suppression, the traditional beauty and decadent beauty, the chastity and unchastity, the asceticism and sexuality, and obscured the notion of the inner wear and outer wear. The destructive deconstruction expressed in the works of Jean Paul Gaultier introduced the elements such as hippy, punk, and kitsch, slashed before making dresses, crumpled unseemly like wastepaper, or made dresses with textures like paper scraps, and through destroying textures, yielded shock effects and tension. Poverty, through borrowing from the outwardly poor-looking elements of design, i.e. the patch work, decolor, dye, fading, fringing, incompletion, and handmadeness, liberated dresses and their ornaments from the outside. The traditional dresses were dresses having certain forms with formative beauty, but Gaultier disassembled dresses and raised questions about the logic of dresses themselves.

Purpose: Previous studies rarely investigated the effects of the metacognitive reading strategies on reading engagement, particularly in globalized higher education, while those studies examined reading problems and engagement with lower reading level. The purpose of this study is to investigate the effects of the metacognitive reading strategies including global reading, problem solving, and supporting reading on reading engagement that include argentic, behavior, emotional, and cognitive engagement in global learning environment. This study investigated research questions: how do global reading, problem solving, and supporting reading strategies affect argentic, behavior, emotional, and cognitive reading engagement? Research design, Data, and methodology: This study collected data via online survey in globalized learning environment. This study applied statistical analyses, such as factor and regression analyses and ANOVA. Results: The results of this study showed that metacognitive reading strategies had significant effects on student reading engagement while they were reading class materials in English for academic purposes. Conclusions: This study provides managerial implications in higher education by providing better strategies to enhance learning skills in global context. In particular, this study provides implications that the effects of problem solving and supporting strategies could be improved by adopting better management systems in globalized education.

Purpose: Geographical relocation has been conducted to alleviate overcrowding and to support balanced regional development in many countries. Previous studies have seldom examined the effectiveness of relocation on job and life dissatisfaction, particularly in the public sector. The purpose of this study is to investigate the determinants of relocation on job and life dissatisfaction. Proposed research questions include the following: i) do working conditions in the new workplace and interactivity affect job dissatisfaction? ii) do social infrastructure and social activity in the new location affect life dissatisfaction? and iii) is there a relationship between job and life dissatisfaction? Research Design, data, and methodology: The study collected data via an online survey and applied statistical analyses such as factor analysis, regression, and ANOVA. Results: The results of this study found that proposed determinants excluding mobility inefficiency and decision-making affect job and life dissatisfaction. The results also showed that there are relationships between job and life dissatisfaction. Conclusions: The results of this study provide both managerial and policy implications of relocation for the public sector. The results of this study implied that better policy should be designed to increase job and life satisfaction that also accounts for the realities of relocation.

Humanities is very difficult area to use the computer. However, recently, convergence trend has increase widely at all of the academic area. Therefore, in this paper, we propose a technical method to use an IT for the popularity of humanities. For this purpose, we implement a path process that use Petri-net to apply digital storytelling to humanities. We also make a structure to connect an examples and questions from sentences or articles as digital storytelling. The digital storytelling consists of six factors; author, synopsis, background, construction, view point, and user's or reader's review. Proposed method provides a process to analyze the data path of a literary work using Petri-net.

As a national enterprise has been expanded over and over, the worldwide energy consumption has been growing necessarily. Moreover, as recently energy spendings are on the increase in countries such as BRICs, it has resulted that a rise in the price of both oil and mineral resources and instability between supply and demand become serious issue in the world resources market. The recent high price of oil and mineral resources have a deep influence on economy and threaten energy security and even national prosperity of Korea. In addition to these, exhaustion of fossil fuels and the enhanced greenhouse effect which results from gases emitted as a result of fossil fuels has been in serious questions which occur a great deal of effort to secure clean energy resources all around the world. As it is considerably possible for Korea that the Kyoto protocol may come into effect on and after 2013, it is essential to require the technological development to promote energy efficiency as well as to develope safe and renewable energy resources. The wind energy technology which converts kinetic energy into electrical energy has been in the focus of the world's attention. In this study, two-dimensional numerical analyses were conducted to observe subsidence aspects of the sea bottom on differently applied loads and various ground conditions.
