Research about U.S. and European countries demonstrated that startups and young firms account for nearly all net job creation. If we want to bring down unemployment and to increase economic growth rate, we need to create new companies and to make them to grow. Credit availability is one of the most important factors for entrepreneurs as they attempt to start or expand a business. For young firms, access to credit for business growth can mean the difference between survival and failure. Equity crowdfunding is an innovative means of raising capital for businesses. Crowdfunding campaigns can give new business access to a large pool of investors. This brings huge benefits for marketing and increase provability of success of business and ROI, so it leads follow-on investment from Venture Capital and Angel investors. In Korea, the survival rate of startups and average growth rate of survivors is far lower than those of the U.S or other countries due to lack of funds for startup or early business growth. Equity crowdfunding can be a new funding source for venture or startups. It can increase startup and survival rate, in addition to the growth rate of survivors, resulting in decreased unemployment rate. In Korea, Equity crowdfunding will be available from 2016. Further study is needed to determine whether the impact of crowdfunding in Korea on job creation will be similar to its impact in the U.S.

With the rise of internet of things (IoT), there have been several studies to analyze the technological trend and technological convergence. However, previous work have been relied on the qualitative work that investigate the IoT trend and implication for future business. In response, this study considers the patent information as the proxy measure of technology, and conducts a quantitative and analytic approach for analyzing technological convergence using patent co-classification analysis and text mining. First, this study investigate the characteristics of IoT business, and characterize IoT business into four dimensions: device, network, platform, and services. After this process, total 923 patent classes are classified into four types of IoT technology group. Since most of patent classes are classified into device technology, we developed a co-classification network for both device technology and all technologies. Patent keywords are also extracted and these keywords are also classified into four types: device, network, platform, and services. As a result, technologies for several IoT devices such as sensors, healthcare, and energy management are derived as a main convergence group for the device network. For the total IoT network, base network technology plays a key role to characterize technological convergence in the IoT network, mediating the technological convergence in each application area such as smart healthcare, smart home, and smart grid. This work is expected to effectively be utilized in the technology planning of IoT businesses.

The purpose of this study is to examine the appropriateness of Regulatory Impact Analysis(RIA) in terms of the technological regulation impact assessment in order to confirm whether the current RIA process reflects the important characteristics of technological regulation. This paper develops a logical framework for analysis of technological regulation and evaluates the appropriateness of the RIA statements submitted by the government departments. From the viewpoint of [technological feasibility of regulation], [synthesis of domestic technological norms], [synthesis of international technological norms], as a result of evaluating the contents of the actual RIA statement on the basis of objective facts, feasibility of alternative analysis, and expert judgment, only 23.4% of the RIA statements were judged "appropriate", and there were no particular differences among the government. As a result of reviewing the appropriateness of RIA statements according to regulatory attributes, the appropriateness of RIA statements on technological regulation with social regulatory and indirect regulatory attributes was rather high. In sum, the level of Korean RIA statements is insufficient to carry out the practical meaning of technological regulation impact assessment. That is, as each government department adopts technological regulation, the understanding of the technological properties of the regulation may not be complete. The RIA statement that does not adequately reflect the technological rationale, hinders the careful review of other regulatory alternatives by exaggerating the feasibility of the technology regulation, at the same time leads to the serious problems that impede the acquisition of competitiveness of companies and the public in the global competition system.

Government R&D support for SMEs is very important and the R&D budget is also increasing. This study suggests a new method for analyzing a performance of R&D programs and analyzes the performance of R&D programs funded by small & medium business administration using the method. We discuss new measures "efficiency" that means short-term performance and "effectiveness" that means long-term performance. Weights based on the R&D programs' characteristics among the various sub-indicators of two measures were derived, and then the final scores were calculated by combining the weights with the responses on the indicators. Finally, this study tests the mean differences between R&D programs statistically. As a results, efficiency of R&D programs shows a significant difference between the R&D programs, while effectiveness does not. Most of the efficiency scores are low, whereas the effectiveness scores are high. The results explain that the R&D programs are managed inefficiently. However, most SMEs predict a positive impact of government R&D supports on effectiveness in the long term. Government needs to try to improve the efficiency of R&D supports because SMEs cannot expect sustainable performance with no improvement in efficiency.

In the era of fierce global competition and short product life cycle, firms have been interested in the technology valuation to improve their competitiveness. As the technology valuation may become a key issue for countries and industries, the development of technology valuation method has become increasingly important. Thus, this study aims to suggest a novel method to assess technology value by applying conjoint analysis to bibilographic information of patent. For this purpose, we firstly identified nine patent indexes categorized in three attributes - technological superiority, marketability and legal rights. Then, we collected actual data on patent transactions including their patent attributes and market prices. Based on the data, we could obtain the patent index values. Finally, we applied conjoint analysis to the prices and patent index values as a basis for technology valuation. The suggested method is expected to be an effective tool for technology valuation by using real transaction data rather than relying heavily on experts assessment.

This study analyzes the economic impacts of Korean R&D expenditure on the industrial structure by technological levels using 2010~2014 Input-Output table data. The industrial structure is reclassified into 4 manufacturing industries by OECD's Technology Intensity Definition. Then, we analyzes the production-inducing and value added-inducing of those industries. As the results of the analysis, it is found that the production-inducing effect by the R&D expenditure has been higher in the middle-high and middle-low technology manufacturing and that the value added-inducing effect has been higher in the middle-high technology manufacturing. On the other hand, the production and value added-inducing effects has been lower in the high-tech manufacturing which is highest in the R&D expenditure. The above results indicate that industrial structure has not been linked with the quality ladder that expresses the enhancement of tech level through R&D expenditure. Based on these results, the policy recommendation implies that R&D expenditure should be concentrated to improve the production- and value-added effects of the high technology manufacturing in order to advance the industrial structure. However, this study has the limitation that the analyses on the dynamic-inducing effects are not carried out due to the lack of fixed capital formation data.

CIP, or Corporate Identity Program is a program to standardize, conforming to a set of regulations, various visual media which form a corporate environment based on the concepts drawn from the corporate strategies in order to actively create a planned but ideal corporate image. However, both the recent corporate renovation and the emergence of a new type of corporations prompted by a rapid change in an corporate environment caused the existing corporate concepts to be adapted to such a change. Particularly various visual media related to a corporate image are getting digitalized, and the emergence of a new and varied type of visual media give rise to a new pattern of the identity design accommodating such changes. It may be improper and insufficient for the existing CIP to be applied on the franchising business which is considered most suitable for the new corporate environment. Business firm's office work has long been operated in an computing environment where the computer does all the work, and an individual home as well as small business began widely using the computer. It may therefore be necessary that the corporate identity design for the franchising business should include not only the use of visual media but new, ultramodern information media as well, departing from the CIP heavily centered on the usual print media. This study, for this reason, separates the identity design for the franchising business from the existing CIP to call it FIP, or Franchise Identity Program, and discusses its concept and details.

In recent years, smart devices have changed the paradigm of education. However, the educational environment and teaching methods could not catch up with this fast improvement and an utmost need for development of educational methods has been realized. In this paper, the general usage of smart devices by elementary school teachers is analyzed and the methods through which smart devices are utilizing smart learning is discussed in the result. A survey of 221 elementary school teachers in Gangwon Province showed that 87.7% of them are currently using smart devices. In addition, teachers were using smart devices with not much difference from ordinary people. The three main motives of teachers who were already using smart devices and those who were planning to take advantage of smart devices were innovativeness, usability and easiness. The reason of need to apply smart devices in education is because of its functionality in various learning types, courses and teaching-learning process methods. Although smart devices have a high efficacy in education but they are not widely utilized yet. In order to solve these problems and be able to take more advantage of smart devices in education, teachers should learn how to use smart devices and a strong sense of willingness is required to make changes in the educational methods. The results of this research on elementary school teachers can be further developed for a greater smart device based smart learning.
