The purpose of this study is to suggest directions for enhancing competitiveness of corporate management by examining how individual creativity and organizational members' value innovation culture perception affect innovation behavior and knowledge sharing, and how innovation behavior and knowledge sharing affect organizational innovation performance and management outcomes In order to achieve these research objectives, the measurement variables of each variable were extracted through previous research and 423 valid samples were analyzed using SPSS 22.0 statistical package program and LISREL 9.1 to verify a hypothesis. As a result of this study, it was found that the creative thinking skills of the individual creativity, the meaningful tasks of the value innovation culture recognition, and the risk - taking culture have a significant influence on the innovation behavior. Only the meaningful tasks of organizational members' value innovation culture perception affect knowledge sharing. Innovation behavior has a significant effect on knowledge sharing and innovation performance, but not on business outcome. In addition, knowledge sharing has no significant effect on innovation performance but has a significant effect on business performance. Finally, we confirmed that innovation performance has a significant effect on management outcome.

The purpose of this study is to suggest strategic approach to expand Korean e-government export. Korean e-government was evaluated as a top level by UN electronic government survey 2014. However its export is very limited. This study reviews the literature related to e-government, and analyze existing Korean e-government export. The results of this analysis are as follows: lack of a law related e-government export, decentralized organizations, insufficient export process, lack of e-government solution for sale, limited funds, deficiency of cooperation between large and small enterprises. This study suggests a strategic approach such as to clarify the purpose of e-government export, to decide government or civilian-oriented export, to establish driving strategy, to improve and develop e-government export related areas. There are many ways for improvement and development of e-government export as follows: to enact a basic law or to revise the e-government law, to integrate functions of separated organizations and establish control tower, to improve export process, to build information sharing system, to develop standardized solution module, and to expand fund to support.

According to Korea Social Trends 2012 report presented in National Statistical Office, based on 2010, single-person household out of all households in Korea ratio is 23.9%, not only this ratio is beyond a family of four's ratio (22.5%) but also overtake couple-person household. Last year, according to financial industry and National Statistical Office, Korea's single-person household is estimated 4 million Five hundred and thirty thousand nine thousand family (25.3%). this mean is Korea's One of four household furniture is single-person household. Furthermore. According to National Statistical Office's report 'Future household projections 2010~2035 Report', In 2035, Korea's single-person household is assumed to increase by 34.3%. Korea's causes an increase of single-person household causes an increase is reduced marriage, increase in divorce, low fertility, increasing older singles etc. also Around the World as well as Korea single person household is increase. Based on 2011, single-person household is reached at 2 hundred million 42 million furniture (This ratio is 13%), China and U.S.A's single-person household ratio close in upon 30%. Sweden and Norway, the Philippines, Denmark is also approximately 40% of all households.

Open economy tightly works with foreign economy. This paper investigates the effect of the shock of foreign bond yield on the credit spreads of domestic corporate bonds in Korea. Foreign bond is referred to as US treasury bond. Credit spreads are defined with the difference between log yields of domestic corporate bonds and log yield of Korea treasury bond. With the data of monthly three-year AA- and BBB- corporate bond yields- ratings, monthly three-year Korean treasury bond yields, monthly US dollar foreign exchange rates, and monthly three-year US Treasury bond yields during the period from October 2000 to September 2014 including global financial crisis period, the paper documents the results as follow. First of all, the yield of Korean treasury and the credit spreads are very sensitive to the increase in the level and the volatility of the yield of the US treasury bond. Changes in the level and the volatility little affect the change of the exchange rate. Second, the change in the level and the volatility negatively affect the level of Korean treasury bond yields but lead to the increase in the level of Korean treasury bond yields at the same time. Third, there exist time lags of the increases of credit spreads by the increase in the level and the volatility. These imply that credit spreads and bond yields are very sensitive to the change in the yields of foreign bonds such as US treasury bond.

Most product consists of various national components, and brand strategy using nationality images is prevalent in marketing field. Country of origin is meaningful consideration for decision making. The purpose is that how consumer evaluate the global brand depending on two-sided dimension of country of origin. This research aims to examine the interaction effect of two-sided country of origin and moderating effect of global identity. In study 1, two-way interaction effect of origin of brand and origin of production was significant with social prestige. In study 2, there-way ANOVA provided marginally significant main effect of origin of brand and global identity. Two-way interaction effect of origin of brand and production was significant with social prestige. Also two-way interaction effect origin of brand and global identity was significant with innovation and social responsibility. Three-way interaction of origin of brand, origin of production, and global identity was significant with social responsibility, this approved moderating effect of global identity. Results contribute to understanding global brands strategy using country of origin effect, and to adding new knowledge to the country of origin literature.

Fine dust has recently become one of the greatest concerns of Korean people and has been a target of considerable efforts by governments and local governments. In the academic world, many researches have been carried out in relation to fine dust, but the research on the economic field has been relatively few. So we wanted to know how fine dust affects the economy. Big data of PM10 concentration for fine dust and fine dust theme stock price were collected for five years from 2013 to 2017. Regression analysis was performed using the linear regression model, the generalized least squares method. As a result, the change in the fine dust concentration was found to have a effect on the related theme stocks' price. When the fine dust concentration increased compared to the previous day, the fine dust theme stocks' price also showed a tendency to increase. Also, according to the analysis of stock price change from 2013 to 2017 based on fine dust theme stocks, companies with large regression coefficients were changed every year. Among them, the regression coefficients of Monalisa were repeatedly high in 2014, 2015, 2017, Samil Pharmaceutical in 2015, 2016 and 2017, and Welcron in 2016 and 2017, and the companies were judged to be sensitive to the concentration of fine dust. The companies that responded the most in the past 5 years were Wokong, Welcron, Dongsung Pharmaceutical, Samil Pharmaceutical, and Monalisa. If PM2.5 measurement data are accumulated enough, it would be meaningful to compare and analyze PM2.5 concentration with independent variables. In this study, only the fine dust concentration is used as an independent variable. However, it is expected that a more clear and well-explained result can be found by adding appropriate additional variables to increase the explanatory power.

The RSA public key encryption algorithm, a few, key generation, factoring, the Euler function, key setup, a joint expression law, the application process are serial indexes. The foundation of such algorithms are mathematical principles. The first concept from mathematics principle is applied from how to obtain a minority. It is to obtain a product of two very large prime numbers, but readily tracking station the original two prime number, the product are used in a very hard principles. If a very large prime numbers p and q to obtain, then the product is the two $n=p{\times}q$ easy station, a method for tracking the number of p and q from n synthesis and it is substantially impossible. The RSA encryption algorithm, the number of digits in order to implement the inverse calculation is difficult mathematical one-way function and uses the integer factorization problem of a large amount. Factoring the concept of the calculation of the mod is difficult to use in addition to the problem in the reverse direction. But the interests of the encryption algorithm implementation usually are focused on introducing the film the first time you use encryption algorithm but we have to know how to go through some process applied to the field work This study presents a field force applied encryption process scheme based on public key algorithms attribute diagnosis.

Healthcare and data science are often linked through finances as the industry attempts to reduce its expenses with the help of large amounts of data. Data science and medicine are rapidly developing, and it is important that they advance together. Data science is a driving force in transition of healthcare systems from treatment-oriented to preventive care in healthcare 3.0 era. It enables customized precision-based medicine that current healthcare systems cannot facilitate, and discovers more cost-effective treatment. Currently, healthcare big data is in the reality of medical institution, public health, medical academia, pharmaceutical sector as well as insurance agency. With this motivation, the medical college of Soonchunhyang university has performed a 'healthcare data science initiative(HDSI)' since 2014. Most of domestic HDSI programs focus on short-term contents such as mentoring and sharing cases for data science. Therefore, it is difficult to provide education tailored to the level of skills and job competency required at the practical site. Soonchunhyang HDSI implemented specialized strategies for improving resilience and response to changes in the IT education of current healthcare with the emphasis on the need for systematic activation of the practical HDSI. The HDSI has been performed as a part of on industry-academic link program in CK-1. Through quantitative and qualitative analysis, this paper discussed the HDSI process, performance, achievement, and implications.
