The purpose of this study was to compare the characteristics of underwear consumer's underwear purchasing behavior through survey. 630 questionnaires were distributed in Seoul and Chonju and 618 with usable data were analyzed frequency and factor analyses, t-test etc. using SPSSWIN 10.0. program. The results were summarized as follows : Most male consumers buy underwears at discount stores whereas most female consumers at chain store. Throughout all four seasons, more male and female consumers do not wear heat-retaining underwears. Most male and female consumers do not have function-fiber underwears nor functional-finishing and natural-dyeing-treated underwears. Most consumers are not satisfied with these underwears. The most important criteria for most male consumers to choose underwears are comfort levels while in action, the sense of touch, comfort levels while wearing them while not in action, pleasance levels; whereas for females are comfort levels while in action, and comfort levels while wearing them while not in action. Male consumers prefer a little bigger-than-their-bodies size, dry and soft fabrics, plain white color; whereas female consumers prefer a little tight size, dry and soft fabrics and plain beige color, Most consumers want to buy functional-fiber underwears made of yellow- soil-and-charcoal-dyeing fabrics which has jade.

In this paper, we look photographes of costumes and composed them as image files by extracting only costume part of the photograph excluding the background part. And we calculated representative color value to implement smart costume coordination program using complementary colors corresponding to representative color values in the costume area. And then, We have solved the problem of over-segmentation caused by extracting the costumes area by applying an anisotropic diffusion algorithm that can remove the noise of the image and flatten the gradient. In order to satisfy users' various needs, we plan to add not only complementary colors coordination but also more various color scheme.

An optic module system is developed adopting multiple colorimetry units for the measurement of multi-pad urinalysis dipsticks. Multiple photometry system instead of moving mechanisms has the advantages of system reliability and simplicity as well as economic aspects due to the recent development of economic color light emitting diodes and stable photo sensors. An integration amplifier with programmable integration time, a current source circuit with selectable and stable current settings were connected through analog multiplexers to thirty light emitting diodes for illumination and ten photo transistors for reading each strip pad. All the circuits are controlled by a microprocessor through a simple set of serial communication commands. The detect ability is eighteen times better than the minimum color difference of the test grading which is 0.013 in urobilinogen in the color space defined in this paper.

This study investigated the development and core mechanism of subitizing in children and adults as well as provides related theoretical and practical discussions. This study was conducted to determine if subitizing changed with the age of participants and if there were differences in subitizing according to the spacing, color, and shape of the stimuli. The subitizing task set (including forty main trials) was prepared. Forty-five children (fifteen each in groups of 3, 4, and 5-year-olds) and fifteen adults were recruited to perform the subitizing tasks. The results demonstrated that the subitizing speed and accuracy of children improved abruptly between age 3 and age 4. Furthermore, there were significant differences in children's subitizing speed according to the spacing and color of the objects. The children's response time decreased when the objects were fully apart or were of diverse colors. In addition, there were partial significant differences in the subitizing speed of children related to the shape of the objects. The subitizing speed of children decreased in a condition (subitizing 5 objects of diverse colors in fixed spacing) when the shapes of the objects were diverse. The subitizing speed of adults only differed according to the space of the objects. The results demonstrate the development of subitizing in early childhood along with the presence of object individuation processing stages underlying subitizing. This study also provides practical information and suggestions for educational curricula that can strengthen the competency of children in systematic and diverse activities.

The synthesis of chimeras is a breeding approach for horticultural crops. In our breeding program, a new diploid citrus chimera, named 'Hongrou Taoye' (Citrus sinensis [L.] Osbeck + Citrus unshiu Marc.), was found arising at the junction where a 'Taoye' sweet orange (C. sinensis) scion was grafted onto Satsuma mandarin (C. unshiu). As an artificial chimera, its fruit traits derived from the L1 cell layer, with juice color and carotenoid complement, in which ${\beta}$-cryptoxanthin accumulated predominantly, similar to those of Satsuma mandarin. By contrast, traits originating from the L2/L3 cell layer, including pollen, seed, and rind aroma characteristics, were the same as those of 'Taoye' sweet orange (the scion). SSR and cpSSR analyses showed that both nuclear and chloroplast genomes of the chimera were a combination of both donor parents. 'Hongrou Taoye' thus combined the valuable traits of both donor plants, and therefore has good potential in citrus fresh market.

The purpose of this study is to find out the usefulness of color contrast program for 50 high school students through comparing the traditional class and the class using the entry software : understanding, utilization, satisfaction, and interest. The results of the study were as follows: First, in the case of the class results, there were no limitations on colors due to materials in the class using the entry software, so students used various colors that match the theory. Second, the activity class using the entry software showed a positive response in terms of utilization, satisfaction, and interest except for the comprehension area, compared to the traditional class using the paper activity. Therefore, this study proved the effectiveness of the practice activity using the entry software in the color management class.

Correlational reasoning is used to analyze results from an experiment and create meaningful relationships among variables. Although there were many recognition development studies, not a single study found the optimal period for the development of logical thinking. Therefore, the purpose of this study is to find the optimal period for students whose logic for variable controlling and correlational reasoning are poor. This study made a logic program treatment subject for students between the 4th and 8th grade whose recognition in reasoning has not been developed in general in order to find the optimal period for their development. The variable-controlling reasoning was performed the program of voice survey and sugared-water melting in subsection survey and sugared-water melting in subsection. And, the correlation reasoning was performed the program of rat's size and tail color, treatment, and effect. As a result of research, students, who were not formed variable controlling and correlational reasoning, could be known to be enhanced through learning, but to fail to be formed the qualitative change like the cognitive development. In other words, the optimal period couldn't be found that is grown the formation of students, who are not formed the variable controlling and correlational reasoning, through learning. It is expected that this research can contribute to the improvement of students' cognitive level and there would be more active researches in different fields to improve the cognitive level.

The aim of the present study was to investigate the behavior and performance of male and female broiler chickens reared under three different colors of light (white, blue and red) in a 23L:1D of lighting program. Day-old broiler chicks were obtained and assigned to six pens (16 males and 16 females per pen). Two pens each were located in three different rooms in an environmentally controlled shed and received the different light colors. All birds received same husbandry conditions. After a 3-day adaptation to the light color, behavior observations (pecking, resting, standing and walking) were made on six focal birds per pen, representing the sex ratio, by direct visual scans for 120 minutes daily for five days a week throughout the 5-week study. Body weights and feed intake were recorded at weekly intervals. On days 19 and 33, welfare indicators (tonic immobility reaction on the 19 and 33 days old; gait scores, foot pad and hock burns scores on 33 days old) were determined. Light color had no significant effect (P>0.05) on the weight gain and feed intake of broilers, but significantly (P<0.05) influenced the feed conversion ratio. Birds receiving the blue light were more (P<0.05) efficient than those receiving white and red lights. Resting was observed to be the major behavior pattern, irrespective of sex or light color. During early growth, resting behavior tended to be lower in birds receiving red light. However, standing and walking behaviors tended to be higher in birds receiving red light in 4 to 18 day-old age and all of experimental periods, respectively. These data indicate that light color can influence broiler performance and behavior.

The art appreciation education is emphasized to develope independent thought and upright value decision in the flood of various image medium. A experience of beauty and a express part related with the sentimental field is focused on directing in the seventh arts curriculum, too. Although the art appreciation education is emphasized, just expressive and functional art texture is still taught in the education spot up to now. Also a appreciative activity is limited simply to describe own feeling intuitionally ; time shortage, difficulty of analysis product, difficulty of guiding appreciation. In this paper I refer that analyze figurative factors of a art product, modify it by applying other program, compare with it and then I develope web base art appreciation system and apply it. As a result I get educational effect. When checking line, form, light and darkness, color, feeling, space and composition of external some factors in a product, formative sense and analytical appreciation is improved.

The purpose of this research aims to find the changes resulted from the collaboration of colors, harmonies, and dynamics within a music. Through this research model, psychologically change of color and harmony, dynamics have explored to collect the resources for the research of the visual media music therapy program. In video media, music is utilized as non-verbal communication in many areas. The connection between melodies and colors, especially, is one of the most effective instrument to reduce the gap between realities and imagination, thus leading emotional inspiration. Gim's(Guided Imagery and Music) model of musical therapy strives to understand inner-side of human nature, and gives an insight into self-understanding. We would like to promote active, and physical model of musical therapy aside from passive existing mode, and apply it as the base resource for our ever-changing society, and teenage education.
