The purpose of this study is to measure the satisfaction factors of user experience of 'Unlimited subscription service' among subscription services and analyze them based on economic and cultural perspectives. By recruiting the '20-'30s who had experienced using service, they attended a survey which was based on the reconstructed honeycomb model of Peter Morville. As a result of the survey, in terms of economic perspective, cost of service, and the ease of subscription inflow were the main satisfaction factors. From a cultural perspective, the familiarity with service and belief and experience of sharing content with people around them were the main satisfaction factors. Therefore, it can be inferred that the satisfaction of the user experience of the subscription service should be firstly satisfied with economic satisfaction, which leads to cultural satisfaction. This study is expected to be used as research data on user experience and satisfaction factors of unlimited subscription service.

The purpose of this study was to be inquired inner contemplation of the tattoo expressed in the modern costumes. For this study, related documentaries and pictures or photos were analyzed in terms of the theretical background for the history of tattoo, the relation between tattoo and the modern western costumes. The primary source of pictures or photos are Vogue, Collections, Collezioni, Harper\`s Bazaar, Modain, Model et Mode etc. The human\`s needs of body decoration had constantly pursued on the body and costumes from the first until lately. Especially in the recents, as the tattoo is implicated a dynamic and charming method of all kinds of body decoration, it\`s used a motive of modern western costumes. The original tattoo means a picture, word etc. that was put permanently onto their skin using a needle and coloring matter. But, these days tattoo is an expression of street style for something new in the subculture. The results were as a follows : The inner meaning of tattoo represented in the modern costumes was classified into two categories. First, the tattooing was a very important factor to complete fashion design through the history of modern costumes, and also the elaborate tattoo of the body was displayed unrestricted formativeness as the skinhead\`s tattoo, raceless\`s ambiguity of street style and artistic decoration, because that can be faded easily. Second, Tattoo Look was expressed as tattoo prints of the see-through, elastic textiles in the modern costumes. That is, the tattoo enhanced the effect of dramatic atmosphere other formative arts as well as the modern costumes by Tattoo Look. Similarity, Tattoo Look could be interpreted as the change of the aesthetic consciousness by the influence of the subculture. Accordingly, in the end of a this century, many experimental designers had applied tattoo to modern costumes. So this study will stand as an important clue to foresee the future costume\`s style and change.

The goal of this study was to develop a haptic communication system that can convey the tactile sensation of fashion materials in a virtual environment. In addition, the effectiveness and how realistically the virtual fabric image of this system delivers the tactile sensation of actual fabric was verified. First, a literature review was conducted through which the tactile attributes of fashion materials were defined that would be implemented in the haptic communication system. Then, a questionnaire for evaluating the tactile attributes of fashion materials was developed. Next, a haptic communication system was designed to convey fashion image experiences in a virtual environment, from which a haptic rendering model was suggested. The effectiveness of the haptic communication system was evaluated by verifying user experiences with questions developed through a user evaluation experiment. The validity of the evaluation questions pertaining to the tactile attributes and the effects of the haptic communication system were verified. Factor analysis was conducted to verify the evaluation of the tactile sense attributes of the fashion material, which identified density, thickness, and elasticity of the material as key factors. As a result of comparisons between the tactile sense through haptic characteristics and through touching, it was observed that regarding density and thickness, tactile sense experience led to greater perceived reality, while this was not the case for elasticity.

Objectives: The purpose of this study is to obtain basic data on the development of a risk communication model through an investigation of risk perception for radon and identify effective risk communication channels. Methods: A questionnaire was used to evaluate differences in perception level according to respective communication channels. A chi-squared test was used to analyze the difference in pre- and post-risk communication by communication channel. One-way ANOVA was used to analyze the difference in the radon risk perception rate for each communication channel. Results: All of the communication channels resulted in increased radon risk perception, but there was no statistical difference between them in terms of perception (p>0.05). However, based on previous findings that it is effective to use a multi-channel approach, it is considered that communication channels based on duplicate avenues is most appropriate. Conclusions: It is expected that this study will be used as basic data to better understand the formation of public opinion about radon risk and to understand the social reaction to each risk factor.

The purpose of this research was to survey and compare the status of science preference of elementary school students with that of middle school students. Preference for science was defined theoretically. According to theoretical model, a questionnaire was developed with piloting and consisted of three parts. First part was for background information, second part, for measurement of science preference and third for measurement of the relevant factors of science preference. The questionnaire was modified for primary school students. In July 2002, the questionnaire was administered to one class per grade of randomly selected 8 elementary and 8 middle schools all over the country and analyzed result of collected 696 elementary school students and 819 middle school students. Middle school students' science preference was low compared with elementary school students, especially in 'emotional response and 'valuational comprehension'. The preference for science became lower especially from 4th to 5th grade and from 8th to 9th grade. The differences of mean science preference were significant by gender. perception of science achievement. and future career choice. The average of science preference relevant factors of middle school students also became lower than elementary students, especially in 'educational factor'. Multiple regression analysis on the science preference showed that important factors were personal ability, the personal traits, rewards in school science and contents of school science, slightly different in elementary and secondary school. The way to promote students' preference for science was suggested on the analysis result.

Objectives : This study aimed to investigate the effects of Angelicae sinensis Radix on longitudinal bone growth rate in rats. We have screened traditional medicinal herbs to develop the longitudinal bone growth stimulator by well-established rat model. A. sinensis was identified as one of the effective herbs in the screening process. Methods : Adolescent female rats were administered A. sinensis at doses of 30 mg/kg and 300 mg/kg for 10 consecutive days. To observe the rate of longitudinal bone growth, tetracycline was injected intraperitoneally on day 8 to stain a fluorescent band on the anew formed bone. To elucidate the mode of action, we observed insulin-like growth factor-1 (IGF-1) and bone morphogenetic protein-2 (BMP-2) expression after A. sinensis administration in growth plate. Results : In the 300 mg/kg A. sinensis group, the length between the proximal endpoint of the tetracycline label and the division line between growth plate and bone was significantly increased compared with vehicle-treated control group. Height of the proximal tibial growth plate was higher in the A. sinensis group compared with control group. A. sinensis also upregulated the expressions of IGF-1 and BMP-2 in the proliferative zone and hypertrophic zone of the proximal tibial growth plate. Conclusions : A. sinensis increases longitudinal bone growth rate in rats. According to immunohistochemistry, A. sinensis increases local IGF-1 and BMP-2 expressions in the growth plate which can be considered as direct stimulation of GH on the local growth plate.
