The pathogenic fungi associated with blight of leaf and stem in peony were leaf spot (Alternaria sp.), powdery mildew (Erysiphe aquilegiae) and rust (Cronartium flaccidum). The infection of leaf spot and powdery mildew begins from late April to midMay and rust was infected in early June. Blight time of aerial part in peony started from late May and the ratio of blight on leaf and stem was more than 50% in late Aug. Yields of root by the incidence time of blight of leaf and stem were 69.1% in late June, 65.4% in late July and $87.6{\sim}92.7$% in August and September. The number of root of more than 10mm in root diameter blighted in late June and July was much lower than in August, but the paeoniflorin content in the former was much higher than the latter.

Recently, smartphone spyware resembles various types of virus components in PCs and has trends getting more and more severe. Users do not perceive the risk factors severely even if smartphone security is very vulnerable in spite of the smartphone spyware growth. Thus, this study observes the influence of information security in selecting smartphone based on the personal inclinations and spyware perceptions. The main variables of study model are such as the degree of personal risk-accepting and the risk of smartphone spyware as independent variables and smartphone purchasing intention as a dependent variable. The model is tested using SPSS 21 packages on the effective 200 samples gathered through questionnaire survey on the present smartphone users. As a result, the two main hypotheses which are "the degree of personal risk-accepting will influence on the perceiving risk of smartphone spyware" and "the perceiving risk of smartphone spyware will influence on smartphone purchasing intention" were significant statistically. Therefore, we could find out information security's influence on the selecting smartphone.

This experiment was carried out to determine the effect of nitrogen application on the cold tolerance of rice plant, with treatment of three levels of nitrogen and three times of application under the low temperature at tillering and panicle initiation stages. The higher cold tolerance variety was increased in plant height and number of tillers on high nitrogen level during the low temperature treatment. Nitrogen content of leaf blade was increased, but carbohydrate content was decreased during the low temperature treatment at tillering stage. Ethylene evolution from leaf was remark-ably increased just after low temperature treatment. Highly significant negative correlation was observed bet-ween the nitrogen content of leaf blade and percentage of filled grain under low temperature condition at reproductive growth stage.

Intensive studies have been focused on conditions for business foundation and the entrepreneurship in light of management, economy, and social psychometrics. This study focused on potential effect of entrepreneurial characteristics on environment for entrepreneurial intentions in establishment of orientation of entrepreneurial intentions. Among various factors affecting on starting small and medium size enterprises, how entrepreneur's personal characteristics is related on entrepreneurial intentions was investigated. Manifest questionnaire was distributed among Venture to the professional graduate students, graduate entrepreneurship, and small business start-educated founders in order to deduce the relationship between the entrepreneurial characteristics and the environment of entrepreneurial Intentions. Previous studies and the literature survey were carried out to support for statistics of the questionnaire. 550 answers were collected and analyzed to find that propensity for achievement, innovation, enterprising, risk taking and creativity are key factors influencing inauguration of an enterprise. We have found that among these, risk taking, creativity, and innovation are analyzed to be as a regression coefficient but enterprising a side regression coefficient. Since this study can find its limitation in that comprehensive fields of entrepreneurship were analyzed in general, the result of this study should be used with caution, until more is known about its accessibility for predicting of success or failure of Start-up Company.

In this study, effects of the psychological characteristics of office workers and start-up preparation on entrepreneurship intention by mediating entrepreneurial opportunity recognition were analyzed. As sub-variables of psychological characteristics, desire for economic achievement, self-fulfillment, and risk-taking tendencies were classified. The collected 357 questionnaires, SPSS v24.0 and Process macro 3.5 were used for empirical analysis. As a result, first, it was showed that self-fulfillment and start-up preparation had a positive (+) effect on entrepreneurial intention, and the effect of desire for economic achievement and risk-taking tendencies on entrepreneurial intention was not significant. Second, it was confirmed that psychological characteristics and start-up preparation had a significant positive (+) effect on the entrepreneurial opportunity recognition. Third, it was found that the effect of the entrepreneurial opportunity recognition on the entrepreneurial intention was significant in the positive (+) direction. Fourth, entrepreneurial opportunity recognition was tested as mediating the psychological characteristics of workers, start-up preparation and entrepreneurial intention. As a follow-up study, it is recommended that studies to analyze moderated mediating effects by the conditional process model including moderating variables and to discover the third mediator other than a mediator used in the research should be conducted.

Many former studies for the entrepreneurial intention dealt with the opportunity-driven motivation, but the actual entrepreneurial motivation is the necessity-driven motivation such as maintaining a living. It is necessary to study the necessity-driven factors for entrepreneurship such as employment barriers and job dissatisfaction. This study focused on the fact that the majority of cultural artists are freelancers or self-employed entrepreneurs. For those who majored in culture and arts, this study was conducted to investigate how an individual's internal and external environment affects the entrepreneurial intention considering the theory of planned behavior. I explored the factors that led individuals to choose entrepreneurial intention between employment and entrepreneurship, and studied the relationship between these factors and the entrepreneurial intention. As the result of the study, the job dissatisfaction and the employment barriers were the pressure factors for entrepreneurship. Job satisfaction had a negative effect on the entrepreneurial outcome expectation and the entrepreneurial intention. The perceived employment barrier had a positive effect on the entrepreneurial outcome expectation and the entrepreneurial intention. An individual's risk-taking orientation is one of the entrepreneurship and had the positive effect on the entrepreneurial self-efficacy. The entrepreneurial outcome expectation and the entrepreneurial self-efficacy had a positive effect on the entrepreneurial intention.
