This study is to explore the ways to increase the export performance of start-up companies, as opportunities are rising along with more companies entering the global market. Thus the study analyzed the factors affecting export performance of the start-up company by mainly looking at the international marketing capabilities of enterprises type of marketing strategy and internal environmental capabilities. The following were derived as factors for marketing 4P strategy: innovation of product, flexibility of export price, differentiation of distribution channels, diversity of promotional activities, and positive-ness of promotion. For internal capabilities of enterprises, innovation of CEO, initiative of CEO, risk susceptibility of CEO, information power of export market, and information power of competitor were derived as factors. Two types of performances were considered for export performance, financial and non-financial. Among innovation of product and risk susceptibility of CEO the non-financial performance of export performance, and only differentiation of distribution channels of marketing 4p strategy the financial performance. It showed that since performance was different depending on the entrepreneurship of the CEO, only innovative products differentiated from small and medium enterprises. risk susceptibility of CEO increased export outlook by corporate acknowledgment and image, creation of potential customers, and financial performance affected only differentiation in distribution channel rather than entrepreneurial spirit, information power, or organizational flexibility because of short business career and insufficient period enough to gain trust. Therefore, start-up companies need to improve their non-financial export performance by increasing innovation of product and risk susceptibility of the CEO. The companies need to widen the differentiation of distribution channels in the financial export performance.

최근 들어 모바일 서비스가 급증하면서 다양한 형태의 모바일 데이터 과금 방식이 등장하였다. 그중 네트워크 사업자인 통신사업자가 특정 앱/서비스에 대해 데이터 사용료를 받지 않고 자유롭게 사용할 수 있게 하는 제로레이팅 방식이 급증하고 있다. 이러한 통신사업자의 비과금행위에 따라 플랫폼 사업자는 자연스럽게 사업적 위기와 기회에 노출되어 있다. 플랫폼 사업자의 입장에서는 위기와 기회를 감안한 전략설정이 필요한 상황임에도 제로레이팅 및 플랫폼에 대해 명확하게 정의하고 분류한 연구조차 부족한 실정이다. 더욱이 제로레이팅으로 인해 플랫폼사업자에게 미치게 될 영향을 분석한 연구는 전무하다. 본 연구는 네트워크사업자의 제로레이팅에 따른 플랫폼사업자의 전략적 대응방안을 마련하기 위해 사업기회 및 위기를 분석하는데 목적을 두었다. 본 연구의 결과는 연구자들로 하여금 제로레이팅과 플랫폼에 대한 이해를 증진시키고, 플랫폼사업자의 입장에서 사업전략을 수립하는데 주요한 참고자료로 활용될 수 있을 것이다.

The mam purpose of this study is to find out how perceived risk elements influence to customers' perceived value and repurchase intention in the electronic commerce environment. To achieve the goal, we set 6 sub-dimensions - privacy risk, social risk, time loss risk, economic risk, psychological risk, and performance risk - based on comprehensive consideration of related studies, and established a research model included 2 factors such as perceived value and repurchase intention to measure performance in internet shopping malls. From 174 customers of the electronic commerce shopping malls survey data have been collected and analyzed based on the covariance structural model method. The results of this study are summarized as follows. Firstly, five perceived risk characteristics of privacy risk, time loss risk, economic risk, psychological risk, and performance risk are significantly positive effect on perceived value. Secondly, perceived value IS very significantly related to repurchase intention in electronic commerce shopping malls. Consequently, we discussed the strategies to create perceived value and repurchase intention in electronic commerce environment. Also we suggested the implications and further research directions.

This study addresses the question as to whether the option prices have useful predictive information on the direction of stock markets by investigating a forecasting power of volatility curvatures and skewness premiums implicit in S&P 500 index option prices traded in Chicago Board Options Exchange. We begin by estimating implied volatility functions and risk neutral price densities every minute based on non-parametric method and then calculate volatility curvature and skewness premium using them. The rationale is that high volatility curvature or high skewness premium often leads to strong bullish sentiment among market participants. We found that the rate of return on the signal following trading strategy was significantly higher than that on the intraday buy-and-hold strategy, which indicates that the S&P500 index option prices have a strong forecasting power on the direction of stock index market. Another major finding is that the information contents of S&P 500 index option prices disappear within one minute, and so one minute-delayed signal following trading strategy would not lead to any excess return compared to a simple buy-and-hold strategy.

We use iterative numerical procedures combined with analytical methods due to Rapach and Wohar (2009) to solve for the dynamic asset allocation strategy for optimal portfolio demand. We compare different optimal portfolio demands when investors in each country have different access to overseas and domestic investment opportunities. The optimal dynamic asset allocation strategy without foreign investment opportunities leads domestic investors in Korea, Hong Kong, and Singapore to allocate more funds to domestic bonds than to domestic stocks. However, the U.S. investors allocate more wealth to domestic stocks than to domestic bonds. Investors in all countries short bills at a low level of risk aversion. Next, we investigate dynamic asset allocation strategy when domestic investors in Korea have access to foreign markets. The optimal portfolio demand leads investors in Korea to allocate most resources to domestic bonds and foreign stocks. On the other hand, the portfolio weights on foreign bonds and domestic stocks are relatively low. We also analyze dynamic asset allocation strategy for the investors in the U.S., Hong Kong, and Singapore when they have access to the Korean markets as overseas investment opportunities. Compared to the results when the investors only have access to domestic markets, the investors in the U.S. and Singapore increase the portfolio weights on domestic stocks in spite of the overseas investment opportunities in the Korean markets. The investors in the U.S., Hong Kong, and Singapore short domestic bills to invest more than initial funds in risky assets with a varying degree of relative risk aversion coefficients without exception.

Identifying validated risk factors in software risk management is imperative for project managers. Although validated risk lists were provided by previous researchers, risk list associated with software project performance areas was not provided as yet. This paper represents a first step toward understanding risk lists by various project performance areas (time, cost, and quality) to help project managers alleviating the possibility of software project failure. Four simultaneous exploratory surveys were conducted with 29 experienced software project managers. Three different risk factor ranking sets for each project performance area were compared with, the risk ranking, which was provided without clarifying specific project performance areas. The risk lists and their corresponding perceived importance were different from previous research results. This implies that identifying risk factors for specific project performance areas can provide additional information for project managers. We concluded by discussing implications of our finds for both research and improving risk management practice.

2008년 세계경제 금융위기 발생 이후 건설 수주물량이 감소되었고, 건설사업관리 (Construction Management) 업체들의 무리한 저가 수주로 인해 업체 경쟁력은 저하되었다. 이로 인해 CM기업들은 리스크 관리 대처능력 저하 등 여러 가지 문제점들이 발생되었다. 시공학적인 측면에서는 리스크 관리에 대한 연구는 지속되고 있지만 CM분야에 대한 리스크 연구는 매우 드물다. 따라서 본 연구는 국내 CM기업들의 리스크 관리 실태를 조사하여 문제점들을 분석하였으며 분석된 문제점들에 대한 효율적 관리를 위한 리스크 인자 도출 방안 및 리스크 관리 시스템 개발방안에 대한 방향을 제시하였다. 또한 본 연구에서 제안에 대한 실무자들의 설문을 통해 개발방안에 대한 효율성을 검증하였다.

To ensure the safe use of pharmaceuticals in the market, US, EU and Japan reached a consensus to adopt ICH harmonised tripartite guideline "E2E Pharmacovigilance Planning" in 2004. Subsequently these regions established and implemented new pharmaceutical safety management systems for patients based on ICH E2E guideline and Risk Evaluation and Mitigation Strategy (REMS) in US or Risk Management Plan (RMP) in EU and Japan. In this study we investigated these new foreign systems and suggested a way to improve Korea's regulatory system for pharmaceutical safety management under Korea Pharmaceutical Law in the view of international harmonization.
