The prediction of heat-up time of an LCD glass plate in LCD glass pre-treatment process has been implemented in the present study. Firstly, the analytical solution for one-dimensional radiation heat transfer from IR heaters to a LCD glass plate is obtained. When the surface temperature of the IR heaters is set at 473 K, the heat-up time of LCD glass to averaged temperature of 383K is 28 seconds. In addition, a three dimensional full CFD analysis using STAR-CD is implemented in an effort to consider the effect of 3-D heat loss through the furnace walls. From the results of the 3-D CFB analysis, the heat-up time increases up to 32.5 seconds under the same conditions. When the IR heater temperature in creases up to 573 K, the heat-up time decreases to 12 seconds for the one-dimensional analytical solution and to 13.5 seconds for the 3-D CFD analysis, respectively.

Recently, the Korea's economy concerns the second money crisis because of the rapid increase of the exchange rate. The Korea's economy which is very dependent on the foreign trade is more sensitive to the change of exchange rates. There are many literatures which analyze the effects of variations of the exchange rates on the secondary and tertiary industries such as the manufacturing industry and IT(Information Technology). But there have been no studies which try to figure out the effects of variations of exchange rate on the primary industries, especially, fisheries' industry. Therefore this paper tries to analyze the effect of price competition structure and the change of exchange rate on foreign fisheries exporting prices in Korea's fisheries import market. This study utilizes OLS(Ordinary Least Squares Analysis) for the analysis in the market of frozen yellow corvina, hairtail, angler fish which are major fisheries importable in Korea. The results show that the exporting country which has the highest market share is more sensitive to the change of the exchange rates itself than that of the other exporting countries' price when it starts to set up its exporting price. And the exporting countries which have low market share are more sensitive to the change of price which country has the highest market share than that of price whose countries have low market share and those of their exchange rate. Also we can find out that the countries which have similar market share try to set up price-setting strategy in the opposite direction. In other words, one country tries to bid up its price, other countries response to rival country by lowering their prices. In the consideration of the fact that most exporting countries aren't affected by Korea's fisheries' prices, the exporting countries in Korea's fisheries import market are more sensitive to the prices of other exporting countries than that of Korea's. This result indicates that the price leader-follower model could be applicable to the Korea's fisheries import market.

There are so many studies on perceived risk and purchasing intention. But the results of those studies were inconsistent; some studies showed the positive effect of perceived risk on purchasing intention; others showed the negative effect. This research supposed that the inconsistence of studies resulted from the difference of group innovativeness and set up research hypotheses : among users from the lower innovativeness group, perceived risk has a negative effect on purchasing intention, but from the higher group, perceived risk has a positive effect on purchasing intention. We compared Internet shopping mall users of South Korea representing low innovativeness with those of China representing high innovativeness. The results provided that among South Korean users, perceived risk had the statistically insignificant negative effect on purchasing intention, but among Chinese users, it had the statistically significant positive effect on purchasing intention. Additionally, this study found that perceived risk influenced users' fun which in turn influenced purchasing intention.

This study intends to provide the groundwork for an establishment of women entrepreneur policy and the guidelines for start-up of women-owned business. The findings of the study are as follows; Women starts business for a financial reasons and this makes up 26 percent, which ranked the highest of respondents motive for starting up a business. The double labor - due 새 the practice of housework and running a business simultaneously - forms 19.6 percent of the bottleneck in operating business. In addition, the worst financial strain, 43 percent, occurred during the business preparatory period. As the entrepreneurship is higher, they are more backed up with support in education and training. In addition, annual net profit of business operated by the older age group is relatively greater. The firm performance is greater as she holds a higher academic degree. As the goal of annual net profit is higher that is set up before the start-up, the net gain turns out to be greater in actual operation, thus resulting in greater effects. The study shows that when they received economic aid, the initial capital had been greatly affected The younger age group makes up the higher percentage of support in education and training. After considering all the findings collectively, the conclusions are as follows; First, the firm performance is affected by the entrepreneurship, schooling, age, and the goal of the female entrepreneur. Second, a support in education and economic does not have a direct effect on the firm performance. However, the study reveals that the entrepreneurship of those who received educational support is higher than that of those who did not. Third, the in-depth interview reveals the facts that how they had been brought up and how the role of the family had a significant effect on their management of business.

The Arena Fragmentation Test(AFT) is designed to analyze warhead performance by measuring fragmentation data. In order to evaluate the results of the AFT, a set of AFT images are captured by high-speed cameras. To detect objects in the AFT image set, ResNet-50 based Faster R-CNN is used as a detection model. However, because of the low resolution of the AFT image set, a detection model has shown low performance. To enhance the performance of the detection model, Super-resolution(SR) methods are used to increase the AFT image set resolution. To this end, The Bicubic method and three SR models: ZSSR, EDSR, and SwinIR are used. The use of SR images results in an increase in the performance of the detection model. While the increase in the number of pixels representing a fragment flame in the AFT images improves the Recall performance of the detection model, the number of pixels representing noise also increases, leading to a slight decreases in Precision performance. Consequently, the F1 score is increased by up to 9 %, demonstrating the effectiveness of SR in enhancing the performance of the detection model.
