The aim of this study was to investigate the effects of socio-demographic and health-related perceptions and twenty dietary behaviors on the superiority and preference, convenient use of and purchase motives of vegetables among 370 women(mean age 43.9) in Seoul and metropolitan and Gangwon area. Data was collected using a questionnaire developed in advanced studies. Almost all subjects rated vegetables more predominantly than grains or meats on the basis of health, diversity, and convenience to purchase. Recognition of healthly funcions of diet, purpose of diet and some dietary behaviors had influence on preference for vegetables. Those who recognized that diet had the function of disease control and prevention, knew the healthy options vegetables provide us, such as, preventing us from geriatric diseases, good sources of vitamins and minerals and considered other motives aside from health issues. From Pearsons's correlation analysis, it was revealed that sufficient time for meal preparation and pleasant eating and desirable life style and dietary attitudes, and a better understanding of nutrition were positively correlated with consumption of more vegetables and convenient use of vegetables. The subjects who recognized the ability of food to help prevent diseases, had a preference for vegetables and attitude to use nutritional knowledge and also considered the nutrition values of vegetables and environment friendliness. Everyday use of vegetables such as consuming a variety of different vegetables, a families favorite vegetables and variation of cooking methods had correlated positively with purchase motives. Therefore to encourage consumption of vegetables, it is important to notice three points continuously; first, practical information of nutritive values of vegetables, the contribution of vegetables in current animal protein foods centered diet and healthful functionalities. Second, the importance of regular diet and steadfast attitude and lifestyle. Finally, the quality of the market where the products are bought such as, quality control of freshness, sanitation, expression of producer and a pleasant environment to shop in.

A necessity of remote control robots or various searching robots etc. that accomplish works given instead of human under long distance and extreme environment such as volcano, universe, deep-sea exploration and nuclear power plant etc. is increasing, and so the development and the research regarding these mobile robots are actively progressing. The wheel mobile robot or the track mobile robot have a sufficient energy efficiency under this en, but also have a lot of limits to accomplish works given which are caused from the restriction of mobile ability. Therefore, recently many researches for the walking robot with superior mobility and energy efficiency on the terrain, which is uneven or where obstacles, inclination and stairways exist, have been doing. The research for these walking robots is separated into fields of mechanism and control system, gait research, circumference environment and system condition recognition etc. greatly. It is a research field that the gait research among these is the centralist in actual implementation of walking robot unlike different mobile robots. A research field for gait of walking robot is classified into two parts according to the nature of the stability and the walking speed, static gait or dynamic gait. While the speed of a static gait is lower than that of a dynamic gait, a static gait which moves the robot to maintain a static stability guarantees a superior stability relatively. A dynamic gait, which make the robot walk controlling the instability caused by the gravity during the two leg supporting period and so maintaining the stability of the robot body spontaneously, is suitable for high speed walking but has a relatively low stability and a difficulty in implementation compared with a static gait. The quadruped walking robot has a strong point that can embody these gaits together. In this research, we will develope an autonomous quadruped robot with an asaptibility to the environment by selectry appropriate gait, element such as duty factor, stride, trajectory, etc.

This study analyzed whether the factors of studying resilience of high school students had a control effect on self-efficacy and academic achievements depending on the degree of stress. For this purpose, this study set the cause and effect model and the research hypothesis through literature and then conducted a survey of 292 people of high school students in G metropolitan city. The analysis of this study showed that recognition ability and communication skill, which are the factors of studying resilience, had different effects on self-efficacy and academic achievements depending on the degree of stress. It has great significance that if the stress level of the high school students is lower, self-efficacy and academic achievements are higher. Therefore, this study suggested how to inspire the academic achievements based on the results of this analysis.

Extracting hand region from images is the first part in the process to recognize hand posture and gesture interaction. Therefore, a good segmenting method is important because it determines the overall performance of hand recognition systems. Conventional hand segmentation researches were prone to changing illumination conditions or limited to the ability to detect multiple people. In this paper, we propose a robust technique based on the fusion of skin-color data and depth information for hand segmentation process. The proposed algorithm uses skin-color data to localize accurate seed location for region-growing from a complicated background. Based on the seed location, our algorithm adjusts each detected blob to fill up the hole region. A region-growing algorithm is applied to the adjusted blob boundary at the detected depth image to obtain a robust hand region against illumination effects. Also, the resulting hand region is used to train our skin-model adaptively which further reduces the effects of changing illumination. We conducted experiments to compare our results with conventional techniques which validates the robustness of the proposed algorithm and in addition we show our method works well even in a counter light condition.

This study aims to examine both the theoretical framework and practical method for the building a subject-oriented collection of information resources form Internet. Through the study, a few conclusions as well as a suggestion were derived. 1. Conclusions : (1) The continuous learning and studying by the librarians working in the information society is required in order that they could have a broader recognition of the existence of various resources from Internet by subject, and that they could be armed with a greater ability to evaluate for the information filtering. (2) The use of a subject directory to collect needed information resources form Internet revealed the necessity for going through many steps linked by hierarchical indexes till arriving at the desired information, and accordingly the great time was needed to conduct the work. (3) In case of using various search engines, since the output of the relevant information largely depends on the adequate defining of the topic, the right selection of search terms and the accurate methods of inputting the keywords, systematic organization of the resources is not simple and easy. The classifying work of collected resources for the topic into the broader categories differs from that of the resources form other topics, for example, psychology, because of the idiosyncrasy of the contents of the each topic. (4) As one method to provide more revolutionary value-added service using Internet, it is necessary for the librarians to learn the skills to build the Web resource pages of subject-oriented collection of information resources from Internet on the specific subject. 2. A suggestion : Since the study did not complete the collection and organization of the information resources from the Internet on this topic, the remaining research and task should be the thorough collection of resources and the building the Web resource pages consisting of interconnecting links of indexes by spending greater time.

This study is to examine the factors affecting success of business withhigh accomplishments in customer recognition and financial aspect in the fashion industry. In addition, through survey on consumers and interviews on industry officials who concerned fashion brand, perceived success factors were compared between consumer and industry groups. This study selected a total of 20 brands, which were 5 brands per 4 categories(e.g., women, men, sports and casual wear), with high customer satisfaction and customer loyalty in consumer's perspective and high revenues, revenue growth, and profit rate in 2004 in a financial perspective. The survey on consumer group and interviews on officials in industry were conducted simultaneously. One thousand respondents were obtained from survey on consumers and 40 respondents were obtained from interviews on industry officials. Multiple regression analysis and t-test were used for data analysis via the SPSS 12.0 program. The result of this study was as following. From a consumer perspective, respondents recognized that both consumer satisfaction and brand revenues were positively related to brand factors of consumer, product and marketing. From an industry's perspective, consumer, product and marketing factors affected consumer satisfaction as a brand success factor. In comparison of perception difference in brand success factors between consumer and industry groups, industry group was more likely to concern about the importance of brand success than consumers. In addition, the consumer group perceived the most highly consumer factor as a brand success factor, followed by product and marketing and external environment factors, while industry group did in order of consumer, marketing, product, and external environment factors, which indicated significant difference in perceptions of the two groups. Through this study on consumer satisfaction to improve positive and amicable buying behavior and comparative analysis on difference of perception of consumers and industry on factorsfor financial ability and revenue increase, the foundation for strategy establishment of brand distinction in fashion industry can be provided.

Among the techniques to protect private information by adopting biometrics, speaker verification is expected to be widely used due to advantages in convenient usage and implementation cost. Speaker verification should achieve a high degree of the reliability in the verification score, the flexibility in speech text usage, and the efficiency in verification system complexity. Continuants have excellent speaker-discriminant power and the modest number of phonemes in the category, and multilayer perceptrons (MLPs) have superior recognition ability and fast operation speed. In consequence, the two provide viable ways for speaker verification system to obtain the above properties. This paper implements a system to which continuants and MLPs are applied, and evaluates the system using a Korean speech database. The results of the experiment prove that continuants and MLPs enable the system to acquire the three properties.
