The purpose of this study is to identify the maturity stages of venture firms through classification analysis, which is widely used as a big data technique. Venture companies should develop a competitive advantage in the market. And the maturity stage of a company can be classified into five stages. I will analyze a difference in the growth stage of venture firms between the survey response and the statistical classification methods. The firm growth level distinguished five stages and was divided into the period of start-up and declines. A classification method of big data uses popularly k-mean cluster analysis, hierarchical cluster analysis, artificial neural network, and decision tree analysis. I used variables that asset increase, capital increase, sales increase, operating profit increase, R&D investment increase, operation period and retirement number. The research results, each big data analysis technique showed a large difference of samples sized in the group. In particular, the decision tree and neural networks' methods were classified as three groups rather than five groups. The groups size of all classification analysis was all different by the big data analysis methods. Furthermore, according to the variables' selection and the sample size may be dissimilar results. Also, each classed group showed a number of competitive differences. The research implication is that an analysts need to interpret statistics through management theory in order to interpret classification of big data results correctly. In addition, the choice of classification analysis should be determined by considering not only management theory but also practical experience. Finally, the growth of venture firms needs to be examined by time-series analysis and closely monitored by individual firms. And, future research will need to include significant variables of the company's maturity stages.

This study presents a model and its implementation methodology assessing not only maturity but also applicability in order to increase the practical usage of open source software(OSS). Since this model measures applicability which can not be assessed by the previous models, it is able to support users in many ways when they introduce OSS for the first time, replace commercial software with OSS, and compare OSS with commercial software. For the purpose of design and implementation of this model, we presented a methodology with 7 phases and conducted a survey to evaluate the appropriateness and reliability of the model. In addition, we proved the practical usability of the model by providing a practical example assessing maturity and applicability of OSS in the area of the infra category on the basis of the methodology. In the future, not only general users but also officers in charge of informatization will be able to select optimal OSS by using this model for industrial application. Therefore, the result of this research is expected to greatly contribute to OSS promotion policy.

This paper showed the difference between the selectivity of gill net by least square method with polynomials in Kitahara's and that by maximum likelihood analysis for Japanese sandfish and Korean flounder. Catch experiments for Japanese sandfish using commercial vessels off the eastern coast of Korea were conducted with six different mesh sizes between October and December 2007 and those for Korean flounder with five different mesh sizes between 2008 and 2009. The mesh size of 50% probability of catch corresponding to biological maturity length of fish was not different between that by least square method and that by maximum likelihood analysis for Japanese sandfish, however, a little different for Korean flounder, that is, those mesh sizes of 50% probability of catch for biological maturity length of Korean flounder were 10.6cm and 10.1cm by least square method and maximum likelihood analysis, respectively.

This study was to develop a introduction program contents for first year nursing students and to verify the effectiveness of the program contents. The effects of introduction program contents for first year nursing students is to identify a career attitude maturity and self-efficacy. The study used a One Group Pre-post Test Design and the surveys were carried out form 5, March to 26, March, 2012. The participants were 129 students of nursing in K university. The data were obtained via questionnaires survey before and after taking the course. The collected data were analyzed by paired t-test using SPSS 15. As a result in analyzing the effect of introduction program contents on career attitude maturity and self-efficacy for first year nursing students, introduction program contents was appeared to influence the self-efficacy. The scores of self-efficacy(t=2.36, p=.002) showed statistically significant improvement after the education. Also there was significant increase in career attitude maturity(t=2.92, p=.004) after the education. The results of this study were the positive effects of introduction program contents on first nursing students' career attitude maturity and self-efficacy. These findings suggest that introduction program contents as a subject would be an efficient way for self-efficacy and career attitude maturity of first year nursing students. and I recommend that various professor teaching method and nursing education contents development with utilizing ICT.

Technology transition from defense technology to weapon system is an important process for defense acquisition program. Many countries such as USA, UK, Australia and Republic of Korea use technology readiness level (TRL) as a tool for technology transition by identifying critical technology elements (CTEs) and assessing the technology maturity. In this paper we review a transition process for the defense acquisition. Then we suggest a method to evaluate system's TRL using each component TRL and integration readiness level (IRL) between each technologies. We apply the method to an ACTD project. A result show that technology maturity is influenced by integration between technologies.

Field trials and research works have shown that the sexually retarded pullets are better equipped to lay larger eggs at the commencement of lay than the pullets grown under the natural conditions with no control over the rate of maturity. The method of delaying the sexual maturity by restricting the nutrient intake is receiving a considerable attention from the research workers, since the nutrient restriction can be a method of reducing the rearing cost. Many experiments were carried out to study the effect of different methods of restricting the nutrient intake of the chicken. But the comparisons between these experiments are difficult because of the differences in the environment, management, type of breed and feed, and in the length of the time during which the feed intake was restricted. In addition the comparisons were not made on an economic basis in these experiments. This experiment was designed to provide information on the reproductive responses to three different methods of restricting the nutrient intake in a egg type stock and to establish which methods are economically profitable.
