Prediction of rice yield during a growing season would be very helpful to magnify rice yield as it also allows better farm practices to maximize yield with greater profit and lesser costs. UAV imagery based automatic detection of rice can be a relevant solution for early prediction of yield. So, we propose an image processing technique to predict rice yield using low altitude UAV images. We proposed $L^*a^*b^*$ color space based image segmentation algorithm. All images were captured using UAV mounted RGB camera. The proposed algorithm was developed to find out rice grain area from the image background. We took RGB image and applied filter to remove noise and converted RGB image to $L^*a^*b^*$ color space. All color information contain in both $a^*$ and $b^*$ layers and by using k-mean clustering classification of these colors were executed. Variation between two colors can be measured and labelling of pixels was completed by cluster index. Image was finally segmented using color. The proposed method showed that rice grain could be segmented and we can recognize rice grains from the UAV images. We can analyze grain areas and by estimating area and volume we could predict rice yield.

Understanding consumers' latent desires for product form has now become a critical issue in product design. Accordingly, product development processes is rapidly changing from product-oriented development to user-centered development. Driver visibility is considered as an important element of driving posture packaging in automobile interior design. This study presents a systematic process for driver visibility analysis approached from affective engineering method that provides design variable selection and screening with respect to the image/impression element of the human visibility. Also, the analysis of front visibility, often called the feeling of "openness", in motor vehicle interior design, is selected and practiced a case study using the systematic process proposed in this study. Twenty six participants evaluated the feeling of openness for thirty motor vehicles following the perceived scale of affective design factors. The results showed that variables such as the height of head lining, the height of cluster housing, the gradient of windshield and the volume of A-pillar were the critical design variables which affect the feeling of openness in a motor vehicle.

We studied the effects of post-annealing treatment on poly(3-hexylthiophene)(P3HT, donor):[6,6]-phenyl $C_{61}$ butyric acid methyl ester(PCBM, acceptor) blend film as an active layer in the organic solar cells(OSCs). For the formation of the active layer, 3 wt.% P3HT:PCBM solution in chlorobenzene were deposited by spin-coating method. In order to optimize the performance of OSCs, the P3HT crystallization and the redistribution of PCBM cluster at P3HT:PCBM composition as a function of post-annealing condition from room temperature to $200^{\circ}C$ were measured by the Hall effect and the UV-vis Spectrophotometer. We thought that the improved efficiency in the OSCs with post-annealing treatment at $150^{\circ}C$ can be explained by the efficient separation or collection of the photogenerated excitons at donor-acceptor interface by P3HT crystallization.

The purpose of this study was to investigate the relationships between lifestyle types, demographic variables, and clothing consumption orientations of male and female adolescents. The method of this study was a survey research by using questionnaires. Subjects were 393 high school students in Seoul. Four lifestyle types of adolescents were derived by cluster analysis: 'digital orientation type', 'material orientation type', 'positive enterprise type', and 'achievement orientation type'. The material oriented students spent high expense on clothes, had higher preference of imported products, had more sensuous consumption orientations, did more impulsive buying, and were more influenced by advertisements than other types of students. Digital oriented students had mothers with low educational background, low academic records, spent small expense on clothes, and had less sensuous consumption orientation. There were more male students than female students in positive enterprise type and the students of this type had upper middle academic records, had higher sensuous consumption orientation and did less impulsive buying. There were more female students than male students in achievement oriented type and this type had high academic records, had mothers with high educational background, and spent small expense on clothes. They had low level on most of the clothing consumption orientation and were especially less influenced by advertisement. This research confirms that the clothing consumption orientations are associated with the lifestyle of adolescent.

The purpose of this study is to investigate whether characteristics of the perceiver make differences in impressions of clothing types in the situation of first impression formation. Questionnaire was used as major method of gathering data. A poll of 650 men h women between the ages of 20∼39 living in Daegu was taken by the author for this study. Factor analysis, cluster analysis, frequency, ANOVA-test and t-test were implemented with the SPSS-package. The characteristics of clothing types used in our experiments include: sexy, masculine, feminine, dramatic, elegant-classic and casual. The results are as follows; 1 . Men favored sexy clothes more than women, whereas women tended to like masculine clothes more than men. 2. Positive, open-minded men were accepting of masculine, feminine, dramatic and elegant-classic clothes, but gave unfavorable responses toward casual clothes. In contrast, positive open-minded women continued to show unfavorable impressions of sexy clothes. Attitude towards clothing affected the outlook towards clothing by the perceiver 3. Clothing-dependent/vain men favored sexy, dramatic and elegant-classic clothes, while clothing-indifferent men tended toward casual clothes. Furthermore, clothing-dependent/vain women were interested in the feminine style, but women in general continued to show negative responses toward sexy and dramatic clothes.

This study investigates the factors influencing service outcomes of group homes and residential care centers, as well as the factors causing any differences between the two service outcomes. 119 and 137 5-6th graders were selected from group homes and residential care centers respectively, using the cluster sampling method. Multiple regression and Blinder-Oaxaca decomposition were used in this study. The results revealed that 'stigma', 'school adjustment', and 'social support' were significant factors influencing service outcomes among children in group homes, while 'stigma', 'primary caregivers' attitude', and 'peer relations' were identified as significant factors among children in residential care centers. The study also found that the mean service outcome score for group homes was higher than that of residential care centers. The 74 percent of this difference in the mean scores was due to the difference in children' characteristics of the two out-of-home care service types. The remaining 26 percent of this difference was due to unobserved characteristics. Finally, the implications of this study in child welfare practices were also discussed.
