Demand of spectrum resource is tremendously increasing recently and this trend will continues in the future due to the wide spread of IT services based on cloud computing and Internet of Things technology and as well as smart devices. Recently, spectrum sharing technology has drawn attention to the spectrum policy makers as a promising way to overcome the shortage problem of scarce spectrum resource. To succeed in commercialization of spectrum sharing technology, it is necessary to prospect the future business ecosystem of spectrum sharing and develop appropriate policies and laws at the same time along with the advance of spectrum sharing technology. The purpose of this paper is to analyze casual relationships between enablers in future business ecosystem of spectrum sharing and propose policies to vitalize spectrum sharing ecosystem based on a system dynamics causal map proposed in the previous research. With the causal map and system dynamics method, it is possible to analyze feedback loops exist in the business ecosystem of spectrum sharing and build policies which optimize positive dynamics in business ecosystem of spectrum sharing. As a result, policy leverages were found in four areas; spectrum supply, spectrum demand, spectrum quality and technology, and spectrum transaction cost. For those policy leverages, 13 policies were identified and intervention timing for each policy was discussed. Finally, the promotion policies of government and market participants to vitalize spectrum sharing ecosystem were discussed.

The study examines the U.S. Small Business Innovation Research (SBIR) program, with a focus on the recent Reauthorization, and compares, in the political context, the U.S. and East Asian countries-Japan, Korea and Taiwan-that adopted the U.S. SBIR program. For the systematic analysis and cross-country comparison, the study employs Kingdon (2003)'s framework-his political theory and Garbage Can Model-to identify political participants and processes underlying the SBIR Reauthorization and to analyze the differences in problem, policy, and politics streams between the U.S. and East Asian countries. For the cross-country comparison, specifically, the study uses various data sources such as OECD, Global Entrepreneurship Monitor, Hofstede's Cultural Dimensions, and World Value Survey. Based on the analysis outcomes, implications of U.S. practices on East Asian countries are extracted as follows. East Asian countries tend to: Have higher entrepreneurial aspiration while lower entrepreneurial activity and attitude than the U.S.; bear higher long term orientation and uncertainty avoidance while lower individualism than the U.S.; and have greater expectations of technology development and higher confidence in political parties while participating less in political action than the U.S. Drawing on the differences, the following policy recommendations are suggested. East Asian countries should: Improve entrepreneurs' access to resources (in particular, financial resource) in order to link their high entrepreneurial aspiration to actual entrepreneurial activities; cultivate failure-tolerating culture and risk-taking entrepreneurs, for instance, by providing a second chance to SBIR-participating businesses that failed to materialize their innovative ideas; and leverage their high expectations of new technology in order to take bold actions regarding their SBIR programs, and update the programs by drawing out constructive dialogues between SBIR stakeholders.

Revolution of Shale gas literally brings about great changes in many spheres. In the past most academic research had been focused on the influence and innovative change in term of economic perspective. But nowadays we should more concern about the security approach and perspective as its status of the future's core energy resources. Revolution of Shale gas has an great influence on the reshaping of global and regional alliance order. There are many international political implications as follows. Contribution of energy hegemony with leading U.S.; Acting as strategic leverage on the reshaping international order; Deepening competition among major states on the construction of energy security and so on. We'd better make a good solution and systematic policies which are preparing for the Shale gas's revolution period including on the understanding about the change on the global energy structure and making a national policy agenda of energy security issues and so on. The thesis like 'to get the energy resources is to get the hegemonic power in the world' will persist. The same holds good of Shale gas case. To meet the revolution of shale gas era, we have important tasks as like making an opportunity to develope not only regional but also international prosperity.

많은 조직들이 여전히 정보보안 수준을 향상시키기 위해 공식적/비공식적 통제 메커니즘(예. 정책, 절차, 조직 문화)의 향상에 상당한 노력을 쏟고 있으나, 이러한 메커니즘의 영향과 효과에 대한 연구는 아직 초기 수준이다. 보안 정책의 실행가능성을 높이기 위한 가장 확실한 방법 중 하나는 준수자들로 하여금 정책을 이해하고 필수요소로 받아들이게 하는 것이다. 하지만 조직 구성원들의 보안에 관한 지식 및 인지의 부족은 여전히 주요한 문제이다. 그동안 많은 연구에서 보안 지식과 인지를 높이기 위해 보안인식 교육의 수행을 주장하였으나 많은 연구에서 제시된 결과는 일관되지 않는다. 따라서 본 연구는 왜 보안인식 교육이 효과적이지 못한지 그 의문에 대한 해답을 찾기 위해 수행되었다.

The article examines the ownership structure and dividend payout behavior of India-listed firms using a panel regression approach. It focuses on family ownership and examines why dividend payouts of family firms differ from non-family firms. The study finds that family firms dominate and have concentrated ownership using data from the NSE-listed regular dividend-paying firms. Although family ownership concentration is high among Indian firms, these firms are not concerned about distributing cash as dividends. Instead, these firms focus on retaining and passing on control from one generation to the next. The evidence shows that family firms pay low dividends and have higher leverage than non-family counterparts. The results support the entrenchment of minority shareholders and the proposition that a high payout signals a reduction in the information asymmetry and level of risk. The study further illustrates that cash dividends tend to reduce the level of risk perceived; however, (cash dividend) leads to the deterioration firm's liquidity and aid in the shrinking of cash among emerging market firms. The originality of the paper lies in factoring ownership concentration while explaining the dividend behaviour from an emerging markets perspective, characterized by high private benefits and weak protection for external minority shareholders.

지금까지 기업의 자본구조에 관한 이론적, 실증적 연구가 무수히 이루어졌지만 중견기업에 관한 연구는 존재하지 않았다. 이 논문은 한국 중견기업의 자본구조를 결정하는 요인이 무엇인가를 실증적으로 탐색하는 연구로서, 2010년부터 2016년까지 한국의 유가증권시장과 코스닥에 상장된 제조업 중견기업을 대상으로 하였다. 부채비율을 종속변수로 하고, 기존연구에서 의미있는 것으로 제시된 변수들 중에서 이용이 가능한 수익성, 기업규모, 자산의 유형성, 비부채성 세금절감을 독립변수로 선정하여 회귀분석을 시행한 결과, 회귀계수들의 유의성이 대체로 높게 나타났다. 제조업 중견기업 표본을 전체산업과 10개의 산업별로 구분하여 분석한 결과 설명변수들 중에서 기업의 수익성이 증가함에 따라 부채비율도 증가하는 뚜렷한 결과를 얻었으며, 유형자산이 증가함에 따라 기업의 레버리지도 대체로 증가했으며, 기업의 비부채성세금절감액이 증가할수록 예상과 달리 부채비율은 전체적으로 증가하는 것으로 나타났다.

This study investigates the factors determining accounting method for R & D costs (capitalize vs. expense) in Korea. Using agency theory and other economic factors, probit and regression models have been developed to distinguish between firms choosing different accounting alternatives for R&D costs. The results are consistent to debt contract, R&D burden and regulation hypotheses both in probit and regression analysis. The size variable has opposite sign in univariate t-test and probit analysis but the signs are mixed and insignificant in regression which may be due to the differences of political environment between Korea and the US. Generally, the results are consistent to those of previous research. The results support the hypothesis that firms with higher leverage and larger burden of R&D costs are more likely to capitalize R&D costs. Partially, larger and regulated firms are more likely to expense R & D costs.

The Comprehensive Measures for a soft landing of Household Debts affecting the credit service of Fisheries Cooperative (FC) have been known to the public in June 2011. Its essential points are as follows: 1) Abolition of Tax-free Regulation, 2) Set limit of loans, etc. per person, 3) Introduce leverage regulations for credit-specialized financial sector i. e. FC, 4) Gradually strengthen loan-loss reserve requirements for card-loan and other credit loans. However, the Financial Policy Measures seem to pay no attention to the Cooperative's Values, Principles and Identity. In this paper, emphasis is be placed on the task of the regulators i. e. Financial Services Commission and Financial Supervice Service to lift the Financial Measures negatively affecting the operation of fund of FCs, and on the establishment of Cooperative identity in order to further develop FCs.
