Modern automatic transmissions equip torque converters with lock-up clutches to reduce the energy loss of hydraulic systems. Instead of simply engaging the clutch disks, the new technology of clutch slip has been developed to improve the overall efficiency of power transmission. There are two major problems with the clutch slip system. The first is how to keep the slip between the two disks within a small range and the second is when to start or stop the slip. In this paper, the second problem is discussed in view of the vehicle economy. With a simple vehicle dynamic model, the fuel economy is calculated to determine the lock-up strategy. Then the lock-up strategy is developed for a slip schedule.

This paper addresses a newly proposed start-up method of the HAUSAT-2 momentum wheel. The HAUSAT-2 is a 25kg class nanosatellite which is stabilized to earth pointing by 3-axis active control method. A momentum wheel performs two functions. It provides a pitch-axis momentum bias while measuring satellite pitch and roll attitude. Pitch control is accomplished in the conventional way by driving a momentum wheel in response to pitch attitude errors. Precession control and nutation damping are provided by driving the pitch axis magnetic torquer. A momentum wheel is nominally spinning at a particular rate and changes speed. This simulation study investigates the feasibility and performance of a proposed strategy for starting-up the wheel. A proposed strategy to start-up the wheel shows that a pitch momentum wheel can be successfully started-up to its nominal speed from rest and be stabilized to nadir pointing.

The purpose of this study is to find out which factors determine the success of start-up in the initial market and what are the most important determinants. For the empirical analysis, the questionnaire related to the analysis of success factors for start-up success was designed according to the quantitative analysis (AHP technique). First, we selected 8 representative success factors for successful start-up in the initial market. In order to determine the degree of priority among these factors, we surveyed 12 entrepreneurs who are interested in entrepreneurship, universities, research institutes, and public officials. As a result of the empirical analysis, 51% of the funds in the tier 1 were ranked as the top priority to determine success factors. Followed by research and development (32.5%), management (8.7%) and marketing (7.8%). In particular, when each of the four items is calculated as 100 according to the result of the tier 1, and the tier 2 is converted, the foreign investment is analyzed as 43.7%. It was followed by 15.14% of R & D facilities, 14.07% of ideas, 8.7% of managerial ability, 7.29% of domestic investment, 5.85% of buyer feedback, 3.3% of development strategy and 1.95% of marketing strategy. Among the eight success factors, overseas investment items showed the closest preference to half, and it was the most important variable that determines the success or failure of market entry. The implication of this study is that many start-ups in Korea expect to receive investment and support from overseas accelerators. This means that overseas investment itself has been recognized as a start-up that makes services and products that can be used in the global market. A high preference for attracting foreign investment is due to the fact that the amount of investment is larger than that of Korea and that it can flexibly cope with the pressure on the performance compared to domestic investors. In this study, it was meaningful that we could confirm this fact through questionnaires of start-up experts. In future research, we need to find a viable alternative through studying how to provide start-up to foreign direct investment at the national level.

This study analyzed the impact of women's self-preservation on their intention to start a business by using self-efficacy as a mediation, reflecting the importance of women's self-preservation to adapt to the new environment of start-up. In particular, in addition to the overall self-preservation, the sub-factors of behavioral delay, compensatory natural strategy, and constructive thinking strategy were also validated. As a research method, 198 people who responded to the online survey were analyzed using Model 4 of the PROCESS macro proposed by Hayes(2018), and indirect effects were analyzed by designating 5,000 bootstrapping samples. The findings were as follows. First, self-efficacy has been shown to have a mediating effect in which women's self-preservation influences their intention to start a business. At this time, the medium effect was shown as a partial medium. Second, the sense of self-efficacy was found to have a mediating effect on women's behavior-oriented strategies affecting their intention to start a business. At this time, the medium effect was shown as a partial medium. Third, self-efficacy was found to have a mediating effect in which women's natural compensatory strategies affect their intention to start a business. At this time, the medium effect was shown as a partial medium. Fourth, self-efficacy was found to have a mediating effect in which women's constructive thinking strategies affect their intention to start a business. At this time, the medium effect was shown as a complete medium. This shows that the higher a woman's self-preservation, the higher her self-efficacy and willingness to start a business. Based on the results of these studies, he made a developed proposal for women's start-ups.

The purpose of this study is to investigate the trends of the start-up research in Korea. To accomplish this, meta-analysis was carried out using text mining methodology by dividing the entrepreneur-related master's and doctoral theses registered in RISS into the first term of entrepreneurship research by 2009 and the second term of entrepreneurship research from 2010. As a result of this study, it can be seen from the three different analysis that the entrepreneurship education and government policy and support are the subject of continuous research topics in the whole period and that the researches on small business start-ups have been studied continuously and conducted more in the second half. In addition, empirical analysis is strengthened in the latter stage of entrepreneurial research. The TF-IDF analysis reveals that many researches on veterans have been carried out in the field of entrepreneurship research, and in the latter period, it was found that many studies related to the elderly were conducted with cultural contents and aging society. In addition, research on brand-related research has been carried out throughout the entire period, and research on venture-related research, characteristics of entrepreneurs, entrepreneurship motivation and start-up strategy have been conducted a lot and female entrepreneurship was also studied. In the latter period, we have emphasized entrepreneurial achievements and found that research on start-ups such as industry-academia cooperation, start-up investment, and social enterprise diversified. This study is meaningful to apply the method which is becoming a recent issue such as text mining and topic analysis to the meta-analysis related to start-up. Future research will need to be undertaken on a variety of more detailed topics related to entrepreneurship.

A hybrid HVDC system that is composed of line commutated converter (LCC) at the rectifier side and voltage source converter (VSC) in series with LCC at the inverter side is studied in this paper. The start-up strategy, DC fault ride-through capability, and fault recovery strategy for the hybrid HVDC system are proposed. The steady state and dynamic performances under start-up, AC fault, and DC fault scenarios are analyzed based on a bipolar hybrid HVDC system. Furthermore, the immunity of the LCC inverter in hybrid HVDC to commutation failure is investigated. The simulation results in PSCAD/EMTDC show that the hybrid HVDC system exhibits favorable steady state and dynamic performances, in particular, low susceptibility to commutation failure, excellent DC fault ride-through, and fast fault recovery capability. Results also indicate that the hybrid HVDC system can be a good alternative for large-capacity power transmission over a long distance byoverhead line.

Under the digital economy, companies are facing a new business environment. Previous studies with a traditional perspectives on start-ups explained they are at a disadvantaged compared to large companies in mobilizing resources and building new relationships. However, recent researches on the digital economy and platform ecosystems have suggested that digital platforms can be an efficient means of overcoming the liabilities of smallness and newness for start-up companies. Through platforms start-ups can secure routes to mobilize resources, collect and analyze market information. Especially as various platorms are established within categorized industry or market, unique characteristics and market awareness regarding an individual startup company have been formed. Accordingly there is also an advantage that startup companies have umbrella effect by participating in the platform. From this point of view, this study describes the process by which a start-up company effectively utilizes a platform to overcome the liabilities of newness and smallness through the case the study of 'Genie the Bottle'. The results suggest that platforms play a crucial role for start-ups to secure awareness and legitimacy and grow the market in the beauty industry in which high consumer involvement is dominant.
