Purpose: The purpose of this study is the time series analysis for predicting the yield of crops applicable to each farm using environmental variables measured by smart farms cultivating tomato. In addition, it is intended to confirm the influence of environmental variables using a deep learning model that can be explained to some extent. Methods: A time series analysis was performed to predict production using environmental variables measured at 75 smart farms cultivating tomato in two periods. An LSTM-based encoder-decoder model was used for cases of several farms with similar length. In particular, Dual Attention Mechanism was applied to use environmental variables as exogenous variables and to confirm their influence. Results: As a result of the analysis, Dual Attention LSTM with a window size of 12 weeks showed the best predictive power. It was verified that the environmental variables has a similar effect on prediction through wieghtss extracted from the prediction model, and it was also verified that the previous time point has a greater effect than the time point close to the prediction point. Conclusion: It is expected that it will be possible to attempt various crops as a model that can be explained by supplementing the shortcomings of general deep learning model.

Purpose - The purpose of this study is to examine the effect of VC investment on the IPO and post-IPO performance of Chinese firms. Design/methodology/approach - By utilizing CSMAR and VentureXpert database, we construct a firm-year panel data covering all listed firms in the Chinese stock market from 2006 to 2018. Findings - First, we find that VC-backed firms are significantly less underpriced than non-VC-backed firms. Our results show that the initial IPO-day return of VC-backed firms is 0.16% lower than that of non-VC-backed firms. Next, we find that VC-backed firms demonstrate significantly worse operating performance than non-VC-backed firms after the IPO. In the next three years following the IPO, VC-backed firms underperform non-VC-backed firms by 0.4% in terms of ROA and by 0.6% in terms of ROE. Research implications or Originality - Our results support the Grandstanding Hypothesis, among several competing hypotheses regarding the effect of VC investment, which suggests that VCs window dress their IPO firms for their early exit at the expense of a poor operating performance of the IPO firms after going public.

In spite of the fact that the food group(Food, Drinks and Health foods & Agricultural and Marine products) occupies little position in total sales of Internet shopping mall, the food group's sales in cyber shopping mall in 2006 have increased 678.1% over 5 years. In addition to the fact that the food consumption pattern has changed from quality-oriented to convenience, health and safety-oriented, the need to decrease the opportunity cost created by housework is rising in the context of increase of women's work participation rate. The wind of change like these will become the foundation on which cyber food industry will be developed. The factors having an effect on consumer purchasing intentions when one buy foods through internet shopping malls are researched in this thesis. For the investigation, women of 697 were surveyed by a questionnaire, and the data were analyzed by the SPSS for WINDOW(Version 12.0). The result is as follows: Factors having an effect on food purchasing intentions are Convenience(Timesaving, Troublesomeness), Customer service(Responsiveness, Reliability, Empathy, Tangibility), Perceived Customer Risk(Economic, Social, Performance risk) and Shopping experience(Easy to find out, Easy process for payment) in order.

Purpose of this study is to explore: 1) the difference in color sensibility evaluation, color attractiveness, and attitude toward the product, 2) the difference in the effect of color sensibility evaluation on color attractiveness, and 3) the difference in the effect of color sensibility evaluation on attitude toward the product between the identical clothing product presented in on-line and off-line settings. Experimental method was applied with 230 male and female university students using stimuli of an on-line site as well as an off-line window display presenting the same white t-shirts. Color sensibility factors of white t-shirt were hedonic, stimulating, active, and spatial senses. These color sensibility factors of the clothing product affected product color attractiveness as well as attitude toward the product. Although there were not differences in color sensibility evaluation, product attractiveness, and attitude toward the product between items presented in on-line and off-line settings, difference was found in the effect of color sensibility on the color attractiveness and attitude toward the product. The effect of color sensibility on color attractiveness and attitude toward the product was stronger in on-line than in off-line setting. Hedonic sense was the most important factor influencing attractiveness of product color and attitude toward the product. In addition, spatial sense affected attractiveness of product color in on-line setting; and stimulating sense impacted attitude toward the product in off-line setting. Based on the results implications were generated.

The purpose of this thesis is to develop a relational model which can explain consumer selection for exporting goods and analyze the effect of corporate image on the relations between country image and consumer selection under global trade environment. The specific objectives are as follows: 1) to suggest a concept of consumer selection and measurement criteria, 2) to analyze correlations among country image, corporate image and consumer selection and 3) to find out the effect of corporate image on the relations between country image and consumer selection. The SPSS program for window and LISREL program were used to analyze the data for this study. The statistical method used in this study was the covariance structure analysis estimating parameters by maximum likelihood method. Path coefficients were tested for t-tests with a statistical significance level of .05. The conclusions of this study are as follows. First, significant correlations were observed among all sub-variables proposed in this study. In addition, significant correlations were detected among country image, consumer selection and corporate image. Second, a hypothetical model proposed in this study was mostly appropriate. Country image had a positive direct effect on consumer selection and corporate image with statistical significance. In addition, it has an indirect impact on consumer selection with statistical significance with corporate image as an intervening variable. Third, corporate image had a significant moderation effect in country image-consumer selection relations. As corporate image levels increased, the effect of country image on consumer selection increased as well. In other words, it has been confirmed that if corporate image levels are high, country image could end up with consumer selection.

To investigate the optimum x-ray tube design for the dental radiology, factors affecting x-ray beam characteristics such as tungsten target thickness and anode angle were evaluated. Another goal of the study was to addresses the anode heel effect and off-axis spectra for different target angles. MCNPX has been utilized to simulate the diagnostic x-ray tube with the aim of predicting optimum target angle and angular distribution of x-ray intensity around the x-ray target. For simulation of x-ray spectra, MCNPX was run in photon and electron using default values for PHYS:P and PHYS:E cards to enable full electron and photon transport. The x-ray tube consists of an evacuated 1 mm alumina envelope containing a tungsten anode embedded in a copper part. The envelope is encased in lead shield with an opening window. MCNPX simulations were run for x-ray tube potentials of 70 kV. A monoenergetic electron source at the distance of 2 cm from the anode surface was considered. The electron beam diameter was 0.3 mm striking on the focal spot. In this work, the optimum thickness of tungsten target was $3{\mu}m$ for the 70 kV electron potential. To determine the angle with the highest photon intensity per initial electron striking on the target, the x-ray intensity per initial electron was calculated for different tungsten target angles. The optimum anode angle based only on x-ray beam flatness was 35 degree. It should be mentioned that there is a considerable trade-off between anode angle which determines the focal spot size and geometric penumbra. The optimized thickness of a target material was calculated to maximize the x-ray intensity produced from a tungsten target materials for a 70 keV electron energy. Our results also showed that the anode angle has an influencing effect on heel effect and beam intensity across the beam.
