This study was developed using the DTP (digital textile printing) jacquard fabrics with a three-dimensional pattern for bag and evaluated the preference and emotional structure. The following conclusions were obtained. Three-dimensional patterns of 12 species using the illustrator program, including six kinds of designs based on the text and six kinds of character types based on the geometry of the basic design was developed. As a result of evaluating the preference of the three-dimensional pattern jacquard fabric, the most preferred fabric was a three-dimensional patterned jacquard fabric with a motif of the Korean consonant "ㅅ". The results of analyzing the emotional dimension of the three-dimensional pattern jacquard fabric, eight factors including simple image, feminine image, exotic image, graphic image, sporty image, masculine image, dynamic image and stereoscopic image were derived. Between emotional factors and preferences correlation analysis showed the stronger the simple image, the feminine image, and the sporty image, the more preferable. It suggested the possibility of a morphological and new fabric for bag, textile design motifs by using Hangul consonants attempt to limit the flatness of the existing geometric form patterns that can be applied to three-dimensional bag whether swirly patterns overcome.

Consumers' awareness of product value, and their product preferences, are becoming increasingly influential in product development, particularly in corporations' efforts in manufacturing products with a competitive edge. Corporations conduct surveys on consumers' product satisfaction and preferences and conduct in-depth studies on consumer needs. They then manufacture products in accordance with the results of these surveys and studies. With the necessity and demand for digital door lock products recently growing, this research sought to explore product competitiveness reinforcement factors that could facilitate market penetration, and to formulate corresponding design strategies. In-depth consumer interviews were also conducted to identify consumer lifestyles and needs. Furthermore, consumer preference images, purchase and use-related patterns, and the status of door lock markets were studied. In the past, to design and manufacture consumer-oriented products, corporations primarily resorted to the improvement of the products' technological features. At present, the users' product preferences and the ways that they use these products are the factors that determine product design. Consumers today tend to adjust their lifestyles according to available products, and prefer products that have greater value in terms of lifestyle and culture. Strategic points for reinforcing competitiveness were presented in this study: first, offering different values that will enhance consumer satisfaction, second, positively developing bio-recognizable methods that will boost consumer preference, third, meeting the consumers' expectations that door lock products should not be mere 'entrance and exit control' systems, but network security systems and fourth, adopting convenient authentication methods backed by advanced technologies.

The purpose of this study is to clarify the spatial characteristics of the children's library and user's behavioral characteristics and to empirically analyze the difference in preference of the spatial characteristics based on the using behaviors. For doing this, this study selected 16 children's libraries in the country as a sampling institute and collected and analyzed 661 questionnaires targeting infants, and the lower and upper graders. The results of analysis are as follows. First, while there was a difference in the relation between the spatial characteristics and the user's characteristics according to ages and sexes, there was no difference in the developing stage. Second, there was a difference in the relation between the spatial characteristics and the using behaviors. Detailed results are as follows. While users who visit the library for reading prefer amenity and peacefulness, those who visit the library for other reasons prefer communication and territoriality. Children prefer diversity, peacefulness and communication when they visit in group rather than to visit individually. In terms of behavioral patterns, users who act quietly prefer diversity than those who act actively. Reading use frequency, as the number of times to visit increased, preference on esthetic sense, dynamics, flexibility, leisure, communication and territoriality increased, but preference on safety decreased. As the length of visit became longer, preference on diversity, self-esteem, peacefulness, dynamics and flexibility increased.

This study aims to investigate the online class preference depending on students' gender and school level. To achieve this aim, the study conducted a survey on 4,803 elementary, middle, and high school students in 17 regions nationwide. The valid data of 4,524 were then analyzed using the Apriori algorithm to discern the associated patterns of the online class preference corresponding to their gender and school level. As a result, a total of 16 rules, including 7 from elementary school students, 4 from middle school students, and 5 from high school students were derived. To be specific, elementary school male students preferred software-based classes whereas elementary female students preferred maker-based classes. In the case of middle school, both male and female students preferred virtual experience-based classes. On the other hand, high school students had a higher preference for subject-specific lecture-based classes. The study findings can serve as empirical evidence for explaining the needs of online classes perceived by K-12 students. In addition, this study can be used as basic research to present and suggest areas of improvement for diversifying online classes. Future studies can further conduct in-depth analysis on the development of various online class activities and models, the design of online class platforms, and the female students' career motivation in the field of science and technology.

The present study examined the reproductive factors and food intake pattern which influence on the breast cancer risk in Daegu${\cdot}$Gyungbuk area. The case subjects were 103 patients newly diagnosed as breast cancer at Kyungpook National University Hospital. The control subjects were 159 healthy women selected by frequency matching of age and menopausal status in the same community. The survey was conducted by individual interviews using questionnaires which include general and reproductive characteristics, dietary habits, and food frequency. The odds ratios were calculated by using unconditional logistic regression after adjusting for confounding variables. The mean age of the subjects was 50 yrs, and mean body mass index was significantly high in the patient group than in the control. The patient group had a significantly higher familial history of breast cancer and a significantly shorter breast-feeding period compared to the control group. It has been found no significant relationship between extrinsic hormone use such as oral contraceptives or estrogen replacement therapy and breast cancer risk. In regard of food habits, a high preference for the cooking method of steaming rather than frying, panbroiling or roasting was significantly associated with lower relative risk of breast cancer. The higher intake frequencies of fruits for all subjects, and seaweeds only for postmenopausal subjects were related with a significantly lower relative risk of breast cancer. The results of the study suggest that the possible risk factors for the breast cancer occurrence include high BMI, family history, less breast feeding experience, preference for the cooking method of frying, and less consumption of fruits and seaweeds. This study provides an useful data for nutrition education to prevent breast cancer for the residents in Daegu${\cdot}$Gyungbuk area.

This study was intended to develop a prototype of new Hanbok Cheollik one-piece based on design extracted through a preference survey on new Hanbok Cheollik one-piece. Through this, it was intended to provide information on patterns that are fundamental to the production of new Hanbok Cheollik one piece. The pattern of the experiment was produced by modifying D pattern, which was selected as excellent in the comparison of commercial Cheollik one-piece patterns. The SPSS 26.0 program was used to analyze the appearance evaluation of patterns. As a result of the 1^st evaluation of appearance and garment pressure, the shoulder, sleeve length, skirt length and sleeve width required modification, reducing the sleeve length by 8.0cm and the sleeve width by 1.0cm in total. The length of the skirt was reduced by 5.0cm and the shoulder end point was reduced by 0.5cm on both sides to modify the shoulder width. As a result of the 2^nd evaluation, the waist area, sleeve width, and skirt wrinkles were required to be corrected, reducing 2.0 cm waist width and 1.0 cm sleeve width and removing wrinkles on the front center and side area. The final pattern was highly appreciated. In future studies, it is thought that research should be conducted through study of Cheollik one-piece pattern according to material and age and the actual wearing experiment according to fabric and age.
