All countries of the world are promoting the creative economy policy to overcome the global economic crisis. Korean government enforces the creative economy policy for the economic growth and job creation. Especially, Technology based startup is actively supported to realize the creative economy. To maximize the efficiency of supporting start-ups, we have to analyze a perception gap of the startup success factors between technology based entrepreneur and startup facilitator. Through the analysis, the supporting policy of startup utilized efficiently the limited resources is necessary. So, the purpose of this study is analysis the difference of the startup success factors which technology based entrepreneur and startup facilitator recognize. To analysis, the start-up success factors derived from previous studies were categorized them as 1) characteristics of the founder, 2) start-up strategy, 3) characteristics of the organization, and 4) start-up environment. Also, The CEO of technology based start-ups and the researcher in national research institute to support SMEs were surveyed. Then, Survey was analyzed by utilizing the ANP methodology to priority derivation of start-up success factors. Result of analysis, Technology Based Entrepreneur was determined that 'composition and expertise of organization' is most important factor for success of startup. On the other hand, Startup facilitator was determined that 'financing strategy of organization' is most important factor for success of startup. Both groups are recognized as important strategy. And start-up environment is recognized as a relatively unimportant. On the other hand, the importance which two groups evaluate about characteristics of entrepreneur and characteristics of organization was different. This study has a academic significance to analyze the priority of the startup success factors between technology based entrepreneur and startup facilitator. Also, It can be utilized practical guideline when policy making about technology based startup.

This study is to identify the structural relationships among undergraduates' individual characteristics(need for achievement, risk-taking propensity), startup education, startup-relevant knowledge and the entrepreneurial intentions. The mediating variables examined were startup education and startup-relevant knowledge. In results, the higher need for achievement the undergraduates get, as the individual characteristics of college students, the more active the entrepreneurial education is to receive. Students with a risk-taking propensity have a positive influence on their knowledge of entrepreneurship and expect to acquire any knowledge of entrepreneurship even if they are not actively receiving entrepreneurial education. However, risk-taking propensity showed that entrepreneurship education and need for achievement had no effect on entrepreneurial knowledge. On the other hand, entrepreneurship education itself shows that it can be a driving force to promote entrepreneurship. In addition, since entrepreneurship education positively affects the entrepreneurial will with the knowledge of entrepreneurship as a parameter, it is necessary for the students to increase entrepreneurial will by getting entrepreneurship education and improving the knowledge about entrepreneurship. In order to do this, the school should formalize regular business start-up education and acquire business startup-relevant knowledge. Therefore, although the individual characteristics of college students influence the will to start a business, it is necessary to find out the will and opportunity of the startup by implementing and acquiring the startup education and startup-relevant knowledge. In this study, some of the universities in the specific area have been studying on the startup education. However, the future study should be conducted on the schools that have startup education nationwide.

This research is conducted a study on the effect of startup mentoring and education satisfaction as well as startup intention on the individual characteristics of university students, therefore, to draw way to increase start up ability of university student as well as their outcome is a primary purpose. Statistics process of sample data for 237 students at the local university in Gwangju is performed an analysis of frequency, reliability, factor, and multiple regression utilized SPSS 2.0 For windows. Individual characteristics except for innovativeness have effected on startup mentoring as well as startup education satisfaction while start up mentoring has effected on start up intention. Only role model function among start up mentoring factors has effected on start up intention while startup education satisfaction has effected on start up intention. As a result, start up intention and its outcome in university will be increased through not only selection of start up mentors with a competence and a passion but also start up mentoring and systematic start up education program fit for individual personality of university student.

It was examined that start-up characteristics of a staged combustion cycle engine powerpack. Among various parameters, valve opening time was considered as a main factor affecting the start-up characteristics. Using monte-carlo method, characteristics variation was analyzed when the valve opening time deviates from the nominal value. As a result, the main fuel valve opening time and the start turbine ending time were significant associated with the startup characteristics. When separating main fuel valve opening time and start turbine stop time, main fuel valve opening time was an important factor. For stable operation, the main fuel valve opening time must be set one second before after driving the start turbine. Likewise, it was confirmed that the startup analysis can suggest an appropriate startup sequence for a stable startup.

In an entrepreneurial ecosystem, the failure rate of startups is extremely high at 90%, and every startup that fails becomes an orphan. This phenomenon leads to higher costs of failure for the entrepreneurs in the ecosystem. Failed startups have many lessons to offer to the ecosystem and offer guidance to the potential entrepreneur, and this area is not fully explored compared to the literature on successful startups. We use a case based method distinguishing a failed startup and a successful startup, studying the entrepreneurial characteristics and firm level factors which cause the failures, in the technology startup ecosystem of Bangalore. We study one of the modes of exit adopted by failed startup entrepreneurs and draw key lessons on causes that culminate in failures. We have identified that factors such as the time to minimum viable product cycle, time for revenue realization, founders' complementary skillsets, age of founders with their domain expertise, personality type of founders, attitude towards financial independence and willingness to avail mentorship at critical stages, will decisively differentiate failed startups from the successful ones. Accordingly, implications have been derived for potential entrepreneurs for reducing the cost of failures in the entrepreneurial ecosystem.
