  • Risk level for each construction work can be very important factors to establish advanced prevention measures. But it is important how to produce it. There are three different methods to set it up for construction situation. They are as follows; 1) occurrence frequency = the number of accident workers of each work kind / yearly accident workers 2) occurrence frequency = the number of accident workers of each work kind / yearly workers 3) occurrence frequency = the number of accident workers of each work kind / the total workers All these three concepts(=averaged concept)are analyzed. Additionally frequency based on discrete curve, and severity based on continuous curve are also combined for producing risk level with more scientific approach. This risk level can be very useful to make prevention plan or take measures at construction sites. This is study result can change existing risk level concept to new concept of it, namely rail way work and in-water work showed be high risk level and RC work be low risk level, different from the situation which we have thought commonly, so far.

  • Purpose: This study was designed to explore the relationship of situational meaning with maternal self-esteem in mothers with high risk newborn. Method: The subjects of this study were 82 mothers with high risk newborn. Data were collected using a translated Family Meaning Attribution Scale and Maternal Self-Report Inventory. Data were analyzed using descriptive statistics, t-test, Pearson Correlation Coefficients and Stepwise Multiple Regression. Result: The average score of the situational meaning in high risk newborn mothers was 64.0l(possible score is between 0-96) and the average score of each item was 1.98. The average score of the maternal self-esteem in high risk newborn mothers was 81.96(possible score is between 26-104) and the average score of each item was 3.15. No significant differences were found in situational meaning according to general characteristics except whether it was a planned pregnancy or not. No significant differences were found in maternal self-esteem according to general characteristics except disease or admission experience during pregnancy. There was significant positive correlation between situational meaning and maternal self-esteem. Conclusion: It is necessary for nurses to provide high risk newborn mothers with care for improving situational meaning that is attributed to the mothers. It can be helpful to improve maternal self-esteem and in the end it will facilitate the maternal transition in mothers with high risk newborn.

  • In Internet of Things (IoT) era, more diverse types of information are collected and the environment of information usage, distribution, and processing is changing. Recently, there have been a growing number of cases involving breach and infringement of personal information in IoT services, for examples, including data breach incidents of Web cam service or drone and hacking cases of smart connected car or individual monitoring service. With the evolution of IoT, concerns on personal information protection has become a crucial issue and thus the risk analysis and management method of personal information should be systematically prepared. This study shows risk factors in IoT regarding possible breach of personal information and infringement of privacy. We propose "a risk analysis framework of protecting personal information in IoT environments" consisting of asset (personal information-type and sensitivity) subject to risk, threats of infringement (device, network, and server points), and social impact caused from the privacy incident. To verify this proposed framework, we conducted risk analysis of IoT services (smart communication device, connected car, smart healthcare, smart home, and smart infra) using this framework. Based on the analysis results, we identified the level of risk to personal information in IoT services and suggested measures to protect personal information and appropriately use it.

  • Risk of loss is a term used in the law of contracts to determine which party should bear the burden of risk for damage occurring to goods after the sale has been completed, but before delivery has occurred. Under the Uniform Commercial Code (UCC), there are four risk of loss rules, in order of application. First, it is agreement that is the agreement of the parties controls. Second, the breaching party is liable for any uninsured loss even though breach is unrelated to the problem. Hence, if the breach is the time of delivery, and the goods show up broken, then the breaching rule applies risk of loss on the seller. Third, the delivery by common carrier other than by seller is necessary: Risk of loss shifts from seller to buyer at the time that seller completes its delivery obligations; If it is a destination contract, then risk of loss is on the seller; If it is a delivery contract, then the risk of loss is on the buyer. Fourth, if the seller is a merchant, then the risk of loss shifts to the buyer upon buyer's receipt of the goods. If the buyer never takes possession, then the seller still has the risk of loss. This paper discusses problems of risk of loss under the American law. Specifically, this paper focuses on the interpretation of UCC sections and analysis of various cases. By comparing, also, UCC and Korean law, the paper proposes some implications of risk of loss issues for Korean law.

  • Suhyup Bank became to be subject to regulation of capital ratio by Basel III which was introduced in order to enhance stability of the financial institution. Accordingly, Suhyup Bank will require recapitalization. It is important to estimate the risk-weighted assets in calculating of Suhyup Bank's recapitalization scale. Therefor, this study aimed to present a scientific model as estimated the risk-weighted assets. Risk-weighted assets are calculated by applying different risk weights for loans, may have a certain relationship with the loans. Results show that the risk-weighted assets is affected by the previous year's risk-weighted assets and influenced the increase in loans during the year. Since the required basic capital adequacy ratio was specified, the risk-weighted assets should be predicted reasonably. Accordingly, on this study it was tried to derive the accounting equation to predict the risk-weighted assets based on management data of a bank since introduction of Basel III. As the risk-weighted assets were weighted differently according to the type of loans, if the accounting equation is derived by using the type of loans, then it would be helpful for the risk management of banks in the long-term. According to this, the increase of loan would be predicted on the basis of past management performance of Suhyup Bank, and for this reason, the future risk-weighted assets of Suhyup Bank were predicted. The result of this study was showed that 98.3% of risk-weighted assets of the previous year, 62.4% of the secured loan changes and 95.1% of the credit loan changes affected risk-weighted assets.

  • In the ever-increasing online secondhand product market, the perceived risk of online used products purchase was identified as a factor influencing consumer purchase intention. The results of this study are as follows. First, the relationship between the perceived risk of online secondhand purchase and purchase intention was presented with somewhat different results for each sub-risk factor. First of all, a significant negative causal relationship between physical risk, time loss risk, psychological risk, social risk and online used product purchase intention was verified. On the other hand, financial risk and functional risk did not show a statistically significant relationship with online used products purchase intention. Second, as a result of research on the moderating effect of purchasing experience, offline purchasing experience of used products and online purchasing experience were verified differently. First of all, the moderating effect of the online purchase experience of used products was significant only in the relationship between psychological and social risks on the intention to purchase used products online. The experience of purchasing used products online is believed to reduce uncertainty about the surrounding response to purchasing used products online and weaken the intention to purchase used products online by reducing tension and concerns about purchasing them. Other risks, such as financial risk, performance risk, physical risk, time loss risk, and online purchase experience of used products, were verified to have no significant effect on online used products purchase intention. In addition, the offline purchase experience of used products did not verify a significant moderating effect on the effect of all perceived risks on online used product purchase intention.

  • It is very important the collaboration and risk management of supply chain between the parent company and its partners in the supply chain risk management(SCRM). It was known that the SCRM approach is very different between a large enterprise and a small and medium-sized enterprise. This paper deals with the suggestion about SCRM structure for a small and medium-sized enterprise. This SCRM structure consist of risk identification, risk assessment, and risk mitigation. We expect that this SCRM structure promote the collaboration between a parent company and its partners to alleviate the supply chain risk.

  • Risk-adjusted return is believed to be one of the optimal parameters to determine an optimum portfolio. A risk-adjusted return is a calculation of the profit or potential profit from an investment that takes into account the degree of risk that must be accepted to achieve it. This paper presents a new procedure in portfolio selection and utilizes these results to optimize the risk level of risk-adjusted Islamic stock portfolios. It deals with the weekly close price of active issuers listed on Jakarta Islamic Index Indonesia for a certain time interval. Overall, this paper highlights portfolio selection, which includes determining the number of stocks, grouping the issuers via technical analysis, and selecting the best risk-adjusted return of portfolios. The nominated portfolio is modeled using Quadratic Programming (QP). The result of this study shows that the portfolio built using the lowest Value at Risk (VaR) outperforms the market proxy on a risk-adjusted basis of M-squared and was chosen as the best portfolio that can be optimized using QP with a minimum risk of 2.86%. The portfolio with the lowest beta, on the other hand, will produce a minimum risk that is nearly 60% lower than the optimal risk-adjusted return portfolio. The results of QP are well verified by a heuristic optimizer of fmincon.

  • The Outsourcing Industry has grown at a swift pace and evolved over time, and the Global IT Outsourcing market has shown signs of a steady growth. In the Korean financial industry, however, IT Outsourcing is not active as that of the advanced countries and there is lack of literature to understand the characteristics of IT Outsourcing in the financial industry. This paper, therefore, analyze the outcomes surveying 40 financial companies in Korea to investigate how IT Outsourcing risk factors affects IT Outsourcing intention. Based on our literature reviews based on number of key articles, journals, and the focus group interviews, IT Outsourcing risk factors are proposed into four different domains: Transaction, Client, Vendor and Environmental perspective. It found that two risk factors (Client and Environmental perspective) are closely related to the IT Outsourcing intention of the Korean financial industry. Finally, this paper concludes that concrete SLAs (Service Level Agreements) of the clients and support of government agencies are important to mitigate the IT Outsourcing risks.
