Innovation and Scale-up of Start-up companies are becoming important national tasks. In the past, it was spread the start-up policy paradigm such as 'Start-up America', 'Start-up Chile', 'Start-up Britain' to overcome the recession globally. However as the economic recovery has become more visible recently in advanced economies, it is shifting from a start-up support policy to a scale-up oriented policy paradigm such as 'Scale-up America', Scale-up UK', 'Scale-up Denmark'. It is necessary to enter the scale-up phase beyond the start-up phase to increase the number of high-quality jobs and to continue economic growth. Therefore, it is necessary to grow the start-up into a strong medium-sized company and to lay the foundation for survival. Therefore, the purpose of this study is to consider the antecedent factors that influence the scale-up aspiration for the start-up firm to grow into a scale-up company, and empirically identifies the differences between the stages of economic development and entrepreneurs in the country. In order to accomplish the purpose, this study predicted scale-up by aspiration which is a predictor of scale-up behavior because it is difficult to achieve visible growth in a short period of time due to the characteristics of start-up companies. In order to empirically explore these relationships, the data were collected from nascent entrepreneurs who have less than 3.5 years of the Adult Population Survey(APS) among the subjects surveyed by the Global Entrepreneurship Monitor(GEM) and the national economic development stage are divided into Innovation-driven, Efficiency-driven, Factor-driven type economies. For the test hypotheses, this study adopted the multi-level model analysis for comparison between national economic development stages and using the R 3.5.0 program. The results of this study are as follows. There is difference between the national economic development and the entrepreneur in the relationship between innovation orientation of entrepreneurs and scale-up aspirations. As the economy of the country develops, the innovation activity of the entrepreneur becomes more active. Since start-ups are heavily influenced by entrepreneurs, there is a difference in the degree of aspiration depending on how innovative an entrepreneur is in the same environment. In terms of the relationship between innovation orientation and scale-up aspiration, the fear of failure was found to differ between national economic development and entrepreneurs. The fear of failure differ from country to country, and this is one of the important factors affecting entrepreneurial activities. It is expected that the factors influencing the growth of the start-up companies which are identified through the results of these studies, will be used to create a suitable scale-up ecosystem according to the national economic development stage.

Objectives: This study was to develop a reliable and valid instrument measuring the reproductive health promoting behavior of undergraduates. Methods: The initial questionnaires were made of 106 items from four domains through literature review. All questionnaire items were revised by an expert group and a pilot test. Data were collected using the revised initial questionnaire of men's 58 items and female's 64 items from 634 male and 685 female undergraduate students. The collected questionnaires were analyzed by factor analysis using varimax rotation to evaluate the construct validity. Results: According to the gender, two measurement were invented and analysed separately. Four common factors consisting of 'safe sex', 'sexual responsibility', 'genital health management' and 'STD prevention' were discovered in both groups. The 'genital hygiene' factor was added as a female factor. Male students' scale was made up 4 factors 16 items and female students' scale was made up 5 factors 18 items. Cronbach's alpha for male scale was estimated to be .892 and female scale to be .882. Conclusions: This scale will make it possible to measure the level of reproductive health among Korean university students. This scale may be useful for developing effective methods of education as well as policy programs for improving the reproductive health of Korean university students.

Purpose - This study aims to verify the construct of the service quality suitable to the characteristics of the business center, to develop the scale that can measure the service quality objectively, compare the diverse business centers in Korea, and present desirable methods of business center management and operation. Research design, data, and methodology - In the first stage, literature research and focus group interviews with current users and actual business experts of business centers were conducted. In addition, 69 early stage scale items were derived. In the second stage, a Delphi survey was conducted on the experts of business and academic circles. The measurement items in the early stage were supplemented and revised. The content validity rate (CVR) of 69 measures was computed and then the experts' opinions were used. As a result, the business center service quality scale, made up of 9 organizing factors and 36 measurement items, was constructed. In the third stage, a survey was conducted on the occupants who were currently using the business center. It was to confirm if the developed business center service quality scale could be actually utilized. The data of 435 samples collected were used. To refine the scale items, the exploratory factor analysis (EFA) was conducted repeatedly. Results - The business center service quality scale, made up of 8 factors and 33 items, was developed again. The 8 factors are reliability, speed, kindness, specialty, responsibility, appearance, convenience, and public interest. The reliability coefficient (Cronbach's Alpha) of each factor is greater than .7. Thus, it was confirmed that there was reliability in the measurement items. Further, the model suitability was verified using the confirmatory factor analysis (CFA), and the convergent validity and the discriminant validity were verified. This proved the construct validity. Through this process, the Korea Business Center Service Quality Scale was developed. Based on factor analysis, the developed business center service quality (BCSQ) scale consists of 4 aspects, 8 factors, and 33 items, comprising the "process quality" aspect: reliability (3 items), speediness (4 items), kindness (3 items) factors, the outcome quality aspect: expertise (3 items), responsibility (5 items) factors, the environment quality aspect: appearance (5 items), convenience (3 items) factors, and the public interest aspect: public interest (7 items) factor. However, according to CFA, the BCSQ scale consists of a total of 4 aspects, 8 factors, and 33 items, comprising the "process quality" aspect: reliability (3 items), speediness (3 items), kindness (3 items) factors, the outcome quality aspect: expertise (2 items), responsibility (4 items) factors, the environment quality aspect: appearance (3 items), convenience (2 items) factors, and the public interest aspect: public interest (3 items) factor. Conclusions - The BCSQ scale could serve as a diagnostic tool that will allow business center managers to determine service areas that are weak and in need of attention, and to improve the service quality of the business center.

The present study has the purpose of analyzing the relationship between entrepreneurial characteristics and success factors of small-scale start-up founders as well as the relationship between success factors and performances of start-up businesses. It is also aimed in this study to determine the structural effects of start-up founders' characteristic upon their performances and by thus, to provide those who prepare for and/or have been operating start-up business with suggestions for stable and successful start-up as well operation. The study resulted in the following outcomes: First, the analysis of the relationship between characteristics and success factors of start-up business found that the empirical characteristics of small-scale start-up business founders might influence every factor for their success including the financial conditions as well as management of shops, products and service. Their psychological characteristics, however, turned out to have influence upon the management of products and service only, but not upon the financial conditions and management of shops, a result implying that the higher desire and creativity small-scale start-up business founders have, the more probable the start-up businesses become successful. Second it was learned from the analysis of the relationship between success factors and performances of start-up businesses that such success factors of start-ups as financial conditions as well as management of shops, products and service could exercise impact upon their performances, signifying that the exact decision making of small-scale start-up founders might affect the performances of small-scale start-up businesses. Third, the analysis of the relationship between entrepreneurial characteristics and performances of start-up founders revealed that both empirical and psychological characteristics of start-up founders might have influence upon the performances of start-up businesses, leading to the conclusion that small-scale start-up founders could achieve higher performances in their start-up when they are highly aware of empirical and psychological characteristics for start-up as part of entrepreneurial characteristics.

The purposes of this study were to find correlations among Fugl-Meyer Assessment scale, gait speed, and Timed Up & Go test (TUG) and to predict gait ability from subscales of Fugl-Meyer Assessment scale. The study population consisted of 30 stroke patients referred to the Department of Rehabilitation Medicine in the Bundang Jaesang General Hospital. All subjects were ambulatory with or without an assistive device. All participants were assessed on Fugl-Meyer Assessment scale and gait speed (m/s), TUG (s). The data were analyzed using independent t-test, Pearson product moment correlation analysis and stepwise multiple regression. The results revealed that all items of Fugl-Meyer Assessment scale, except passive joint range of motion were significantly correlated with gait speed and TUG. In particular, sensation score, lower extremity motor and coordination score have a significant correlation with gait speed and TUG (p<.05). The sensation score and lower extremity motor score were important factors in comfortable gait and maximal gait speed. Their power of explanation regarding comfortable gait and maximal gait speed were 63.0% and 65.0%, respectively. The sensation score and lower extremity coordination score were important factors in TUG. Their power of explanation regarding TUG was 55.0%. These results showed that Fugl-Meyer Assessment scale is significantly correlated with gait speed and TUG. Therefore Fugl-Meyer Assessment scale is an appropriate assessment tool to predict gait ability of patients with stroke. Further study about gait speed and TUG by change of Fugl-Meyer Assessment score is needed using a longitudinal study design.

The effects of culture conditions on succinic acid production and its possible scale-up have been studied. Mannheimia succiniciproducens LPK7, engineered for enhanced production of succinic acid and reduced by-product secretion, was used for the experiments. Mannheimia succiniciproducens LPK7 is a knock-out strain of wild type deficient in the ldhA, pflB, and pta-ackA genes, and is derived from Mannheimia succiniciproducens MBEL55E. Process optimization of factors including optimal temperature, pH, carbon source, and nitrogen source was performed to enhance the production of succinic acid in flasks. To observe scale-up effects, batch fermentation was carried out at various working volumes. At a working volume of 7.0 l, the final succinic acid concentration and yield were 15.4g/l and 0.86g/g. This result shows similar amount of succinic acid obtained in lab-scale fermentation, and it is possible to scale up to larger fermentors without major problems.
