This paper is targeting on developing pre-test Methodology for start-up as tuning successful business modelling with their implementation. Start-up is asked to a complete preparation and analysis for business to enhance the success possibility. In this stream, Start-up should test the validity of their business model before starting a business. This paper deliver alternatives to meet this requirement. Overall, this paper suggest two different approaches. First, by literature review, this paper prove the importance of BM in success factor analysis of high-tech start-up. Second, This paper prove BMO Model as the best practicing model to assess the validity of BM. Additionally, this paper, BMO will be utilized to bring significant implications to sort out enhancing strategies of BM validity.

In the mean time, management ability of founder, entrepreneur ability, technical and function ability were considered for management skill of founder and alalyzed effect of the factors on performance of small firm were examined. Effects of strategic intention of founder of small firm were analyzed by the strategic viewpoint. At this time, strategy of small firm was divided into product-service reform differentiation strategy, marketing differentiation strategy and cost leadership strategy. This study distributed questionnaire on CEO of small firms in Daejeon and Chungnam area for accomplish the study objective and it collected a total of 145 copies of questionnaires. As a result of analyzing collected questionnaire, this study deduced the following study results and suggestions. First, results different from those of existing studies were found Since sales, net income and profit rate of small firm were not high cause economic depression on the whole. Second, entrepreneur ability was found to be required for success of business creation. Entrepreneur ability of founder was the factor that affects both financial and non - financial performance of small firm. As such, entrepreneur ability can be regarded as the most important factor for success in business creation of small firm. Accordingly, entrepreneur ability is the most important source for success in business creation of small firm. Third, strategy of small firm was found to be the important factor that affects the non-financial performance even if it could not give significant effects on financial performance. Thus, product service reform differentiation strategy, marketing differentiation strategy and cost leadership strategy have significant effects on non - financial performance of small firm. Accordingly, it is required to operate small firm with strategic mind - set for small firm to achieve success. This study analyzed the effects of feature of founder and strategy of small firm on business performance of small firm through practical analysis on small firms in Daejeon and Chungnam area, and deduced meaningful results. However, Since this study collected data on small firms in Daejeon and Chungnam only, there is a limit in generalizing the results of this study to all small firms in Korea. Companies answering to this questionnaire process were mainly wholesale and retail service companies. In addition, there is a limit in that it failed to analyze feature of representative type of industry due to limit in number of sample, it is required to divide representative type of industry and to compare and analyze types of industry in future studies.

We have studies in 38 subjects (19 control and 19 experiment ) for development of functional food for postpartum body control. Mean age of control and experimental subjects were each other 30.4 and 29.0 years old, and mean body mass index were 20.2 and 21.4. Total weight gain during pregnancy of control and experimental subjects were 14.0kg and 19.8kg. We measured change of weight and liver activity after parturition for 3 months. It shows that weight not reduced until 30 days in postpartum but significantly decreased during 30 days to 90 days. The mean weight of control and experimental subjects were decreased 3.15kg and 6.46kb at 60 days (p<0.05), 4.47kg and 7.44kg at 90 days (p<0.05). In this study, hemoglobin, GOT and GPT level were not changes before and after of experiment, respectively.

In this study, some experimental results of the peroxide-degradation process of polypropylene(PP) in a co-rotating twin-screw extruder to produce controlled rheology polypropylene(CRPP) are presented. The peroxide was dicumyl peroxide(DCP) and the concentration of DCP was in the range 0-0.3wt%. It was found that the rheological properties of PP change significantly during reactive extrusion. Melt fiow index(MFI) increased with DCP concentration. Intrinsic viscosity decreases with increasing DCP concentration. From dynamic rheological data, number ave-rage molecular weight(Mn), weight average molecular weight(Mn) and molecular weight distribution(MWD) were cal-culated. Results indicated that Mw decreases and MWD becomes narrower with increasing peroxide concentration. Especially, particle size distribution of CRPP decreases with increasing DCP concentration by chemical powdering process, and anti-slip floor paint, CRPP(DCP 0.2 wt%) powder by 10phr was friction coefficient 2.15μ, abrasion resis-tance 511.18%.
