Recent global economic recession and recession of employment have made various efforts to revitalize entrepreneurial ecosystem by presenting entrepreneurial spirit and creative talent development as national top priority strategy in major developed countries. Based on data from the Global Entrepreneurship Trend Report (GETR), which has been conducted by the Venture Small Business Division and the Korea Entrepreneurship Foundation since 2015, the study will be conducted by the entrepreneurs of 10 countries in 2015 and 2016 The components of mental ecosystem were compared and verified. The results showed that entrepreneurship education effect and entrepreneurial environment showed positive relationship with entrepreneurship of individual and organization. Also, entrepreneurship education effect, entrepreneurial environment, individual entrepreneurship. On the other hand, organizational entrepreneurship was not found to have a significant effect on entrepreneurial type (livelihood / opportunistic entrepreneurship). In this study, entrepreneurship education as a lifelong education is required in order to enhance entrepreneurial ecosystem in Korea and to increase the quality of entrepreneurship which is increasing quantitatively. Finally We emphasizing the importance of creating a favorable entrepreneurial environment and offer some suggestions.

In the basic research field, quantitative expansion is carried out with active support from the government, but there is no research and policy data suggesting systematic investment plans or data-based financial requirements yet. Therefore, this study predicted future financial requirements of basic research support programs by using time series prediction model. In order to consider various factors including the characteristics of the basic research field, we selected the ARIMAX model which can reflect the effect of multi valuable factors rather than the ARIMA model which predicts the value of single factor over time. We compared the predictions of ARIMAX and ARIMA models for model suitability and found that the ARIMAX model improves the prediction error rate. Based on the ARIMAX model, we predicted the fiscal spending of basic research support programs for five years from 2017 to 2021. This study has significance in that it considers the financial requirements of the basic research support programs as a pilot research conducted by applying a time series model, which is a statistical approach, and multi-variate rather than single-variate. In addition, considering the policy trends that emphasize the importance of basic research investment such as 'the expansion of basic research budget twice', which is the current government's national policy task, it can be used as reference data in establishing basic research investment strategy.

The purpose of this study is to examine the effect of police investigation environment on perception toward legalization of private investigation. To enhance the completeness, this study conducted a survey on police officers in service and analyzed the survey data through statistical technique. The results for examination on how police investigation environment influence on perception toward legalization of private investigation were as follows. When the 'work burden from long-term cold case' composing the police investigation environment is high, the police officer highly evaluated the growth potential of private investigation, showed positive perception toward private investigation market, and showed intention for re-employment at private investigation agency after retirement. When the police officer experiences more difficulties from 'investigation other than criminal case', the police officer highly evaluated the growth potential of private investigation and showed intention for re-employment at private investigation agency. In addition, when the police officer thinks that there are a lot of difficulties for "Limited investigation on specialized area", the police officer showed positive perception toward growth potential of private investigation and private investigation market. In addition, police investigation environment showed significant result on legalization of private investigation. The result also verifies that as the difficulty of crime investigated by the police is getting higher quantitatively and qualitatively, it is necessary to introduce private investigation system which is specialized and able to investigate for a long time. This study hopes that this study result would be utilized as the grounds in signing the bill for introducing the private investigation system.

Compared to the quantitative increase in women's workforce, women's status in the organization remains poor. When it needs diverse perspectives and flexibility cope with the environment, it is an urgent challenge for companies to manage women in organizations. In this study, it is explored the internal factors of the organization that allow women managers to be more immersed in the organization. While previous researches have focused mainly on employment equality policies, this study expands the scope of existing research by considering the organization's internal support factors, such as mentoring, education and training, and organizational atmosphere. The female manager panel data showed that mentoring, education and training, and organizational climate all increase the leading influence of female. This leading influence affects organizational commitment and mediated between organizational internal factors and organizational commitment. In other words, it has been found that it is important for female managers to take the initiative in their position as well as the internal support of companies for female managers to immerse themselves in the organization. This study could contribute to solving the dilemma of the use of women's workforce by companies that fail to recover all investment costs such as recruitment, education, training, and compensation of excellent women's workforce.

Vector quantization algorithm based on fuzzy clustering has been widely used in the field of data compression since the use of fuzzy clustering analysis in the early stages of a vector quantization process can make this process less sensitive to its initialization. However, the process of fuzzy clustering is computationally very intensive because of its complex framework for the quantitative formulation of the uncertainty involved in the training vector space. To overcome the computational burden of the process, this paper introduces an array architecture for the implementation of fuzzy vector quantization (FVQ). The arrayarchitecture, which consists of 4,096 processing elements (PEs), provides a computationally efficient solution by employing an effective vector assignment strategy during the clustering process. Experimental results indicatethat the proposed parallel implementation providessignificantly greater performance and efficiency than appropriately scaled alternative array systems. In addition, the proposed parallel implementation provides 1000x greater performance and 100x higher energy efficiency than other implementations using today's ARMand TI DSP processors in the same 130nm technology. These results demonstrate that the proposed parallel implementation shows the potential for improved performance and energy efficiency.

This study is to investigate how science and engineering integrated (SEI) lessons affect science-gifted students' perceptions about engineers and engineering practices. Twenty elementary science gifted students participate in this study, and they reflect what engineering practice means such as managing limited time and budget. The SEI lessons with 24 hours class time are used as an intervention. The main data are collected with 'engineer and engineering drawing test', open-ended questions and interviews about the drawing, and focus group interviews about the lessons. The transcribed interview data are analyzed using mixed methodology of quantitative (descriptive and paired t-test) and qualitative methods. The result shows that the SEI lessons have positive impacts on the science-gifted students' perceptions about engineers and engineering practices such as engineering design. After the lessons, the students perceive engineering and engineers in a desired way such as engineering as a social practice that many experts work collaboratively, the interaction between engineering and society, and the importance of ethics and social values in engineering practice.

Purpose: The purpose of this study was to develop a mercury database for food commonly consumed by Koreans. Methods: Target foods for a mercury database were selected from dietary survey data of the 2007-2009 Korean National Health and Nutrition Examination Survey (KNHANES). Data for mercury contents of foods were collected through literature review. Among 702 food items reported by 24 hr dietary recall method, the contents of mercury for 300 food items were selected with systematic evaluation from the literature, which provided analytical values, and those of 56 food items were imputed by using a conversion factor. Results: The mercury database developed in this study covered 50.7% of all kinds of consumed foods and 95.1% of total amount of food intake reported by 2007-2009 KNHANES. In the database, the geometric mean of mercury contents in food items was the highest in the fishes and shellfishes group ($41.13{\mu}g/kg$, n = 101) followed by mushrooms ($18.93{\mu}g/kg$, n = 12) and seaweeds ($5.92{\mu}g/kg$, n = 14), and the lowest in the meats group ($0.15{\mu}g/kg$, n = 17). Conclusion: The developed mercury database can be used to estimate the dietary mercury exposure of Korean people, and the method for development of a mercury database would be helpful to researchers in development of a new database for other food borne hazardous substances.

To establish a foundation to objectively interpret Chosun history, we construct people network of the Chosun dynasty. The network shows scale free network properties as if most social networks do. The people network is composed of 1,379 nodes and 3,874 links and its diameter is 14. To analysis of the network dynamics, whole network that is composed of 27 king networks were constructed by adding the first king, Taejo network to the second king, Jeongjong network and then continuously adding the next king networks. Interestingly, betweenness and closeness centralities were gradually decreased but stress centrality was drastically increased. These results indicate that information flow is gradually slowing and hub node position is more centrally oriented as growing the network. To elucidate key persons from the network, k-core and MCODE algorithms that can extract core or module structures from whole network were employed. It is a possible to obtain new insight and hidden information by analyzing network dynamics. Due to lack of the dynamic interacting data, there is a limit for network dynamic research. In spite of using concise data, this research provides us a possibility that annals of the Chosun dynasty are very useful historical data for analyzing network dynamics.

China's mobile communication market has been growing quantitatively and qualitatively since 2000. Currently, it has secured 1.27 billion mobile subscribers and many of the Korean companies try to enter the Chinese market and cooperation with companies in China is being held. Thus understanding of the Chinese markets is the key to better prepare for future international competition. This study is to identify factors affecting switching intentions and behaviors for Chinese mobile subscribers to other mobile service providers by the PPM and it is to derive correlations between strategies of mobile service providers and users' switching intention by the groups classified by ARPU. We conducted a survey targeting 270 Chinese mobile users and analyze it by using Smart PLS 2.0. In conclusion, push effects have positive influence on intention to switching and relational switching cost among mooring effect have significantly negative influence on intention to switching In particular, intention to switching depending on the groups classified by a level of their ARPU have been shown as significantly different. This study will extend theoretical range of PPM theory in explaining users' switching behaviors and contribute to establish strategies to enter the chinese market.
