There are two definite objects for developing the startup transient of liquid rocket engine. One is to achieve the repeatability of startup to ensure higher reliability, and the other is to reduce the time of the startup transient. Typically in the initial phase of engine development as we are currently opposing, it is hard to estimate engine startup time due to the lack of experiences. In this work, a startup transient analysis tool was developed with the introduction of the mathematical model for each component of pump-fed liquid rocket engine system. Startup transient was investigated for a 25 ton class gas generator cycle engine to find necessary time for reaching steady state from startup and this enabled to reveal dynamic characteristics of the engine.

Startup has lot of limitation such as time and budget shortage, and few human resources, and may be under the very stressful condition. Naturally in these context, there is always conflict among the startup team members, but the impact of conflict on teamwork or team performance has not been empirically tested. This study examines the relationship among the conflict, teamwork and team performance in startup context. Different two types of conflict and four factors of teamwork for team performance are identified from a literature review and tested; task conflict and relationship conflict as antecedents, teamwork was composed of communication, collaboration, coordination and cohesion, leading to team performance. 142 data points were collected from startup representatives to test these hypotheses. PLS data analysis indicated that the task conflict positively effects on all teamwork factors, but relationship conflict has statistically significant effect on only two teamwork factors, collaboration and coordination in negative relationship. Teamwork factors effects on team performance except communication. Based on the results, we proposed practically several team management skills for startup managers, leaders and even members, and explained theoretical contributions.

Purpose : With the proliferation of O2O platform services that combine offline and online services, many startups are fiercely competing to lead services in the O2O service market. While the prospects for growth in the O2O service market are optimistic because of the close convenience to life, startups can achieve corporate performance only through close cooperation and partnership with suppliers. The purpose of this study is to verify the effect of O2O-based startups' and suppliers' cooperation in supply chain management on SCM performance through supply chain partnerships and startup satisfaction with suppliers. Research design, data, methodology : Data were collected from O2O service-based startups and hypotheses were verified through frequency analysis, exploratory factor analysis, reliability analysis, confirmatory factor analysis, feasibility analysis, and structural equation path analysis. In addition, the mediating effects of supply chain partnerships and startup satisfaction on suppliers were verified. Results : As a result of this study, IT utilization of the O2O startup cooperation method affects the financial perspective of supply chain partnership and SCM performance. The contract implementation of the cooperation method had an impact on the financial and innovation growth perspectives of the SCM performance, and the communication of the cooperation method had an effect on the supply chain partnership, startup satisfaction in the supply chain, and the innovation growth perspective of the SCM performance. Supply chain partnerships had an impact on the financial, innovation growth, and customer perspectives of SCM performance and startup satisfaction within the supply chain had a significant effect on innovation growth and customer perspectives. Conclusions : The implications of this study identified the factors that can improve SCM performance through the cooperation method of O2O startup, supply chain partnership and startup satisfaction with suppliers, and it is significant that the causal relationship was identified by the structural model through the supply chain cooperation factors derived by characteristics. Based on the empirical results, as the services of O2O startups grow, it is expected that empirical research and practical activation of academia should be considered as important in the cooperation of the supply chain.

This study analyzed the actual impact of central and local governments' startup mentoring programs on the entrepreneurship and early startup business performances of company owners and prospective owners. To analyze the participants' hidden intentions, literature review, in-depth interview, and focus group interview research methodologies were used consecutively. The following results were obtained. First, participants with higher expectations toward the mentoring programs tended to evaluate the programs more negatively, with a substantial number of interviewees responding that the quality of the programs was subpar. Second, startup mentoring programs seem to have had positive effects on building entrepreneurship. The effect was especially significant in areas such as creativeness and innovation. Third, the mentoring programs did not have a significant impact on business performance, suggesting the need for institutions' active participation in mentor-mentee relations and programs. Fourth, most participants evaluated mentoring programs as unsatisfactory, meaning that the programs do not meet the intention and purpose of the institutions providing them. Based on these analyses, the academic importance of this study was highlighted and ways startup mentoring programs can improve in the future were suggested.

This study is intended to look into the effects of small business startup environments on failure burden and startup failure. To achieve this, a survey was carried out to 300 small business CEOs in Seoul. The results were as follows. First, the effect of startup environments on failure burden showed that management environment, business environment, internal organizational environment and external organizational environment had a negative effect on failure burden. Second, the effect of startup environments on financial and non-financial losses showed that startup management environment, startup business environment and internal organizational environment had a negative effect on financial and non-financial losses. Third, the effect of failure burden on startup failure showed that failure burden had a positive effect on financial and non-financial losses. Consequently, this study indicates that internal organizational commitment and communication are important attributes affecting failure burden, financial and non-financial losses, compared with management quality, entrepreneurship and business environment.

The startup characteristic of liquid propellant rocket engine should be focused on the stable ignition of combustion chamber and gas generator. Also, to lessen the propellants consumption during this period which doesn't contribute to the flight thrust, the engine has to be transferred to the nominal mode quickly. Because of the risk of test, it is impossible to develop all the startup cyclogram or the specifications of engine by test, so the precedent numerical approach is quite necessary. In this study we developed a mathematical model for the startup phenomena in a liquid rocket engine driven by gas generator-turbopump system based on the commercial 1-D flow system analysis program, Flowmaster. Using this program we proposed a methodology to obtain the specifications of turbine starter and the opening time of shutoff valves for the stable startup of the engine. To verify this methodology we qualitatively compared the analysis results to the typical startup curve of the published engine, then found it is quite well matched.

This study explored how early stage entrepreneurs think about key success factors of startup and its impact factors. Previous research on key success factors of startup focused on high technology industry or explored retrospectively main reason of their startup success. However, preparatory entrepreneur who lacks career and social experience has different point of view of startup success, because of their situation which they overcome various problem of entrepreneurial process. This research surveyed key success factors and impact factors of entrepreneurial success based on 905 preparatory entrepreneur. We witnessed that preparatory entrepreneur recognizes various key success factors and found different key success factors according to the attribute of preparatory entrepreneur. We found that man, team startup and non technology related startup in 20s age emphasized procuring superior manpower. But solitary startup and previous career related busienss and long preparation term in 30s age recognized importantly about the entrepreneur's ability. Also, preparatory entrepreneur who considered importantly sales promotion and thorough preparation has different attribute. We can find a unique point that Funding capability was not significant attribute. Finally we suggested implication and further research agenda to foster young entrepreneur based on major findings.
