The purpose of this research was to determine the degree to which Small-to-Medium Enterprise (SME) owners and operators in Mountain Province were willing to take on financial risk to invest in the capital markets as a potential additional source of income, as well as the extent to which these five indicator variables-particularly their income, expenses, financial goals, liquid cash, and insurance coverage-were influenced by demographic factors. The study used a quantitative approach and employed a descriptive survey research method. The results show that the SME Owners and Operators in Mountain Province have minimal knowledge of capital market investments which makes them moderate investors with a neutral level of financial risk tolerance toward capital market investment. Their marital status, net income, and educational attainment significantly influence their financial risk tolerance level. The respondents also believe that engaging in the capital markets will grow their businesses. Further, the extent of influence of Income, Expenses, Liquid Cash, and Insurance Cover on the financial risk tolerance of the SME owners and operators in Mountain Province a great extent; thus, making them careful in investing in the capital markets, and it is primarily affected by their Net Income. Consequently, the financial goals of SME owners and operators in Mountain Province have a vital role in their financial risk tolerance level.

EN ISO 14971:2012 a risk management standard approved and applied as a European standard in 2012, will be adopted and applied as ISO 14971:2019 published in December 2019, ISO/TR 24971(Guidance) published in June 2020 from May 2022. After that, it is applied to IVDD surveillance and IVDR new and conversion, and the manufacturer is already preparing for application or is starting preparation for application. In addition, 98/78/EEC IVDD applied from 1998 will also be applied as REGULATION (EU) 2017/746 IVDR from May 2022. In particular, in IVDR, the requirements for post-marketing investigations such as Post Market Surveillance (PMS), Summary of safety and performance(SSP), Periodic Safety Update Report(PSUR) and Post Market Performance Follow Up(PMPF), which were not required in the existing IVDD, increased, and the contents were also specified. This study focused on ISO14971:2019 among these strengthened and newly applied regulations, and tried to present a detailed analysis and application plan of Post Market Surveillance (PMS) required by 2017/746 IVDR.

This paper aims to investigate the time-varying systematic risk of the stocks of Korean logistics firms. For this purpose, the period from January 1991 to October 2016 was examined with respect to 21 logistics companies that are listed on the Korea Exchange. The systematic risk of the logistics stocks is measured in terms of the Capital Asset Pricing Model (CAPM) beta for which the sensitivity of a stock is compared to the return changes of the whole market. Overall, the betas of the stocks of the Korean logistics companies are significantly lower than those of the market unity; however, it was revealed that the logistics betas are not constant, but are actually time-varying according to different economic regimes, which is consistent with the previous empirical findings. This finding is robust across different measurements of the logistics betas. In addition, the impact of macroeconomic factors on the logistics betas was examined. The present study shows that the logistics betas are positively associated with foreign exchange-rate changes.

Project Financing(PF) was introduced from the way of banks' conditional financing that take buried oil as security and offer required money to oil explores which have weak loaning ability in the U.S. 1930s. After that PF has developed with financial market and it has been activated in the market of Korea since 'An Institution about Private Financing Invitation Promotion' was established. Started with I-Hwa Ryoung tunnel project, PF has been used in the Metropolitan Area Airport Highway and etc. But because of the risk that occurred by PF's complexity and uncertainty, PF has not been used fully and there are only few practical examples. The purpose of the present study is to investigate how to decrease, identify and extract the risky factors of project that being planned by PF.

Real Time Pricing(RTP) is used not only to stabilize the price volatility in electricity market, but to hedge the price risk for Load Serving Entity(LSE). This paper presents an efficient method to reduce the risk of the price volatility in real-time electricity market. For designing the RTP, load patterns of customer are calculated by applying the demand elasticity and customer's utility is also analyzed to compute the RTP revenue through the risk-attribute of the LSE. In the end, the distribution of the LSE's profits can be evaluated to lead the optimal RTP value, depending on the level of customer's participation. Results from the case study based on PJM data are reported to illustrate the proposed method.

This paper empirically examines the portfolio diversification effect using data from both KOSPI and KOSDAQ. In KOSPI market, portfolio diversification effect disappears when more than 18 stocks are added in the portfolio. About 63% of portfolio risk is eliminated. In KOSDAQ market, the maximum portfolio diversification effect is achieved when 17 stocks are at least included in a portfolio. The maximum cumulative risk reduction is 35%.

In this paper, we consider a risk-minimization hedging problem for a special European contingent claims. The existence and uniqueness of strategy are given constructively. Firstly, a non-standard European contingent is demonstrated as stochastic payment streams. Then the existence of the risk minimization strategy and also the uniqueness are proved under two kinds market information by using Galtchouk-Kunita-Watanabe decomposition and constructing a 0-achieving strategy risk-minimizing strategies in full information. And further, we have proven risk-minimizing strategies exists and is unique under restrict information by constructing a weakly mean-selffinancing strategy.

본 연구의 목적은 국내 자본시장에서 외국인투자자의 감시자 역할로부터 발생하는 영향력이 글로벌 금융위기에 따라 차별적으로 관찰되는지를 실증적으로 분석하는 것이다. 본 연구에서는 2003년부터 2015년까지 총 2,919개의 기업데이터를 수집하여 외국인투자자 지분율과 기업의 자기자본비용 사이의 상관관계분석을 글로벌 금융위기 상황여부에 따라 수행하였다. 실증분석 결과, 외국인투자자는 일반적으로 기업에 대한 감시자 역할(monitoring role)을 효과적으로 수행함으로서 국내 자본시장에서 순기능적인 역할을 하고 있었다. 그러나 글로벌 금융위기 시와 같이 자본시장의 위험 수준이 극대화될 경우에는 이들의 감시자 역할이 효과적으로 이뤄지지 못하는 것으로 관찰되었다. 본 연구는 외국인투자자의 영향력이 자본시장의 위험 수준에 따라 달라질 수 있음을 제시하였다는데 시장참여자들과 학계에 공헌 할 수 있을 것으로 기대된다.

In this study, a microbial risk assessment was performed for the bacteria Vibrio parahaemolyticus, which causes a foodborne illness following the consumption of Jeotgal, a fermented seafood in South Korea. The assessment comprised of six stages: product, market, home, consumption, dose-response, and risk. The initial contamination level (IC) was calculated based on the prevalence of V. parahaemolyticus in 90 Jeotgal samples. The kinetic behavior of V. parahaemolyticus was described using predictive models. The data on transportation conditions from manufacturer to market and home were collected through personal communication and from previous studies. Data for the Jeotgal consumption status were obtained, and an appropriate probability distribution was established. The simulation models responding to the scenario were analyzed using the @RISK program. The IC of V. parahaemolyticus was estimated using beta distribution [Beta (1, 91)]. The cell counts during transportation were estimated using Weibull and polynomial models [δ = 1 / (0.0718 - 0.0097 × T + 0.0005 × T²)], while the probability distributions for time and temperature were estimated using Pert, Weibull, Uniform, and LogLogistic distributions. Daily average consumption amounts were assessed using the Pareto distribution [0.60284,1.32,Risk Truncate(0,155)]. The results indicated that the risk of V. parahaemolyticus infection through Jeotgal consumption is low in South Korea.

본 연구는 미국 내 다양한 지역들의 소비위험 분산의 결정요인을 실증적 접근을 통해 분석하고자 한다. 이를 위해 미국 내 8개 경제권역의 다양한 조합을 소비위험 분산 집단으로 간주하고 거시, 금융변수의 통제 하에 해당 소비위험 집단들의 산업구조 편차가 각 집단의 소비위험 분산에 미치는 영향을 살펴보고자 한다. 본 연구의 실증분석 결과에 따르면, 소비위험 집단내 산업구조 편차가 심할수록 해당 소비위험 집단의 자본시장 경로를 통한 소비위험 분산은 더욱 활발해지는 것으로 나타난다. 이러한 연구결과는 지역 간 경제통합에 있어서 산업구조가 이질적인 지역일수록 자본시장을 통한 소비위험 분산 집단을 형성하는 경향이 강하다는 사실을 암시한다. 또한 본 연구의 실증결과는 현재 진행되고 있는 FTA나 여타 경제통합 진행과정에서 보다 효율적인 경제통합 달성을 위해 회원 국가 혹은 지역의 산업구조가 고려되어야 함을 시사하고 있다.
