Nowadays, within the paradigm shift of e-learning, MOOCs service has been expanded among a number of global leading universities and this has affected our domestic universities' e-learning to look for different possibilities and new challenges. In consideration of our domestic educational condition, it is required to contemplate how university e-learning can be changed and developed with focus on MOOCs from the perspective of convergence development. This study suggests plans for convergence development in university e-learning based on MOOCs with conceptual model. We conducted the studies on relevant literature of university e-learning and MOOCs, expert consultation, SWOT analysis, survey for those involved of e-learning centers, etc. Through this process, we developed a final plan which integrates 'open advanced education course service', 'teaching and learning curation service', 'teaching and learning practice service', 'creative teaching and instruction method development and sharing service', and 'cloud based educational platform support service', etc with the perspective of convergence development. Also we designed convergence development plan based on MOOCs. It is assumed that the result of this research provides advanced plans for development of university e-learning and the base for further discussion of introduction and application of MOOCs service in domestic university.

With the expiration of main patent of printing method, public interest now has shifted to 3D printing. In this, it needs to shine a light on the negative effects, particularly in the socio-economic aspect of 3D printing. By analyzing the existing research findings, policy reports and press releases, the negative effects of 3D printing and its countermeasures were derived. The main drawbacks of 3D printing includes the following: It might cause 3D printing-related crimes(e.g. printed weapons, intellectual property infringement, etc.) and it poses a big threat to other related business sectors.(e.g. potential job loss in molding and medical equipments manufacturing industries) What's more, the nature of 3D printing that it is easy to operate attracts lots of people, which then leads to serious social and environmental problems-product liability, ethical issues, environmental pollution, and finally government's blindly excessive investment in 3D printing. To avoid such potential risks, the government should establish and enforce the institutional law, and guidelines. Government's rational investment decision is also inevitable for the short-term and long-term sustainability of 3D printing.

Present study aims to describe who are the non-regular female workers in South Korea. The dominant form of employment of Korean female non-regular workers is characterized by instable contract, low wage, long-time work and exclusion from the state and occupational welfare. Also, non-regular female workers are not homeogenous but there are various groups of women among female non-regular workers including young part-time workers, high educational middle class contract professionals, particular contract workers such as home-schooling teachers. However, it would worth noting that over 40s, low-educational, low income, breadwinning women who are working in sales, service, and simple handy job are most likely to become non-regular female workers in South Korea. Those women are the major group among non-regular female workers. The public assistance (in cash) for non-regular workers are necessarily needed for them at this point in South Korea.

In e-learning industry which represents the convergence of IT and education, the standard of e-learning content development cost has been calculated according to the guideline or standard of existing similar industries without considering the characteristics of the industry until today. The absence of contents development cost standard related to e-learning has been recognized as one of the most difficulties in e-learning industry. The calculation of the content development cost without reflecting the characteristics of e-learning industry has bad effects such as the degradation of content quality and development of e-learning industry, and the growth obstruction of them. This paper suggest a standard of development cost for e-learning content development considering the characteristics of e-learning industry. We analyse current problems and the characteristics in e-learning industry, and define the development cost standard. We propose the methodology for developing e-learning industry and for contributing quality improvement of e-learning content.

This study focused on the idea that consumers who are dissatisfied with their body form tend to be more interested in weight control behavior. This research connects this relationship with consumers' risk perception on the internet and consequent decision hesitation behavior. Empirical results extracted three factors of weight control behavior: diet, physical treatment, and medication and exercise. Weight control behavior was different by gender but not by age. Consumers who were dissatisfied with their body form were likely to do exercise, but other types of dissatisfaction (weight dissatisfaction and height dissatisfaction) were not significantly related to weight control behavior. Weight dissatisfaction influenced perceived size risk significantly when shopping online. Diet, physical treatment, and medication had significant influence on perceived size risk when shopping online. Perceived size risk had significant influence on decision delay and offline switch behavior. This study took a convergence approach, which connects consumer characteristics with online shopping behavior.

Due to globalization, more foreign-owned small businesses have been joining the South Korean economy. In order to better support the growth, this study's purpose is to identify foreign entrepreneur demographics and company information as well as entrepreneurial motivations and perceived success factors. To fulfill these goals, a survey of 98 immigrant entrepreneurs from 31 countries doing business within the local Korean market was conducted. The results show that most foreign-owned small businesses are service-oriented and primarily started for intrinsic reasons. It was also identified that the perceived business success determinants that the government can most directly affect are skills-based, rather than infrastructure or financially oriented. Furthermore, top issues include unreliable employees, language barrier and too much competition. The findings of this study are particularly relevant to both academics and policy makers alike because almost no prior foreign entrepreneur-focused research has been conducted in Korea.
