As the ubiquitous paradigm that allows users to access the Internet anytime and anywhere is expanding, the expectation and interest of the Internet is increasing. As interest in the Internet has increased, interest in open source hardware has also increased. As a result, the maker, who is a creator who actually uses the digital production tools to create a product that he thought, is emerging as a new trend. As these makers shared how to make products, the 'maker movement', an open source manufacturing movement, spread. In the case of the domestic market, the government's policy support is also stimulating the maker movement. However, compared to developed countries, there is not enough awareness and environment of maker culture, and only open platform hardware and software are used without special education / development equipment or kit for maker.

Social commerce is a kind of internet shopping mall in which consumers purchase the products with other consumers through mutual interactions including the development of SNS(social network service). Social commerce has expanded rapidly as a mainstream online shopping mall over the past five years driving consumers to purchase more fashion products providing the cheaper prices than open market internet shopping mall. The purpose of this study is to identify the important parameters of social commerce characteristics and consumer characteristics that affect repurchase intention and word-of-mouth intention. A 221 survey questionnaire was distributed to men in their 20's and 30's who live in Seoul metropolitan area. The data were analyzed utilizing Cronbach's ${\alpha}$, factor analysis, and regression analysis using the SPSS 18.0 program. The results revealed, first, that in terms of social commerce characteristics, three variables(website reputation, interactivity, and product scarcity) influenced repurchase intention. Among them, website reputation identified as the most important factor influencing repurchase intention and word-of-mouth intention. Second, with regard to consumer characteristics, interest and a tendency toward impulse buying affected the repurchase intention, and interest and internet shopping experience have influenced the word-of-mouth intention. Among three variables interest in social commerce identified as the key factor affecting both repurchase intention and word-of-mouth intention. The results of the study provide the practical implications and suggest the business strategies to enhance social commerce in the future by identifying the key social commerce characteristics and consumer characteristics that influence male consumers' buying behaviors.

Mobile tour guide applications help tourists to search for and visit their surrounding POIs(Points of Interest) of their locations and to obtain their guide information. With the development of wearable devices like smart watches and wearable glasses, people using multiple mobile devices are increasing; a tourist may use a hand-held device, a wearable device or both to obtain tour information. However, most mobile tour guides using mobile devices provide the tour information with little consideration of their hand-held and wearable characteristics. In particular, a tourist with multiple mobile devices who search for the tour information from multiple mobile devices must input their intention separately to each device. To alleviate these problems, we propose a mobile tour guide system with the following features: one is to reduce redundant user input by sharing the touring context between hand-held and wearable devices; the other is to present tour information according to capabilities and usage pattern of the devices. The proposed system guides tourists by complementing disadvantage of the devices and also minimizes user interaction between applications and tourists.

The purpose of this paper is to estimate the revenue function of the personal income tax of Korea. Unlike the traditional approach employing the data adjustment, this paper explicitly includes the explanatory variables of the tax rate or schedule in the revenue function and further estimates the functions by income sources such as labor, interest, global, and dividend incomes. One of the main findings is the GNP elasticity of the combined personal income tax is around 1.2 when evaluated on the basis of the estimates of the GNP elasticities of tax revenue from respective income sources, which is somewhat smaller than those in the previous studies. Another interesting result is that the GNP and interest rate elasticities of the interest income, are found around one and .15 respectively, as expected. Also, the estimate of the tax-free income coefficient is significantly negative in the labor income tax revenue function.

This study examines effects of small group cooperative learning on areas of mathematics such as number and calculation, figure, and measurement, and changes of attitude-interest in math in elementary schools. Seventy eight second graders from Jinhae City were divided into the experimental group and the control group. The experimental group was subdivided into small groups of four students who belonged in different levels of math performance. The subdivision was renewed whenever each area was covered. An examination paper which had been developed by Ministry of Education & Human Resources Development and Kyeongsangnamdo Office of Education was given to the subjects. Also, a questionnaire was developed and given to the participants. The results show that, in general, the small group cooperative learning had good effects on the students' ability to solve math problems and, in articular, greater effects on the ability of low-level students. It is revealed that the interaction between the students in small groups affected their attitudes toward and interest in mathematics in a positive way, but did not make perceivable changes in self-confidence of the young Learners.
