In this paper, We propose reasoning system for object recognition and space classification using not only visual features but also contextual information. It is necessary to perceive object and classify space in real environments for mobile robot. especially vision based. Several visual features such as texture, SIFT. color are used for object recognition. Because of sensor uncertainty and object occlusion. there are many difficulties in vision-based perception. To show the validities of our reasoning system. experimental results will be illustrated. where object and space are inferred by bi -directional rules even with partial and uncertain information. And the system is combined with top-down and bottom-up approach.

In this study, consumers' perception and consumption behavior of blended tea were investigated. Also, consumer perception of Siberian chrysanthemum, consumption behavior, and awareness of efficacy were investigated. As a result of the survey, it was confirmed that it was necessary to develop a blended tea with taste and flavor characteristics that consumers prefer, having the capability of relieving stress, and preventing cold or respiratory disease. In addition, the degree of recognition of Siberian chrysanthemum was very low, and the recognition of the efficacy appeared in the order of 'cold relief' and 'respiratory disease relief'. Factor analysis results, safety attributes, health attributes, product attributes, marketing attributes, and sensory attributes were factorized into five factors, and after analysis, it was concluded that the sensory attributes of taste and aftertaste were considered the most important. Consumers surveyed appeared to consume blended tea for 'relieving mood or stress relief', to enjoy the taste, and to prevent cold or respiratory diseases. Siberian chrysanthemum displays efficacy in cold relief and relief of respiratory diseases. Therefore, developing Siberian chrysanthemum as a blended tea could be a practical application that can expand the range of its use, making it more popular and increase its commercial applications.

This study was implemented for the purpose of analyzing the Job Competency level of accredited and non-accredited program's graduates. And we were seeking way to manage realistic and effective way of Accreditation of Engineering education. In order to achieve the purpose of this study, survey and FGI were done. The study was: accredited program's graduates thought more positively than non-accredited program's graduates, and graduates felt that 11 Job Competencies Level of Work Performance were lower than the needs of job performance. The conclusions of this study were summarized as follows: First, between accredited and non-accredited program's graduates, we could see significant recognition difference about the perception of the needs of job performance. This was because Design curriculum were reinforced and accredited program's graduates had attended design program at accredited program. Second, accredited program's graduates felt higher than non-accredited program's graduates about the perception of level of work performance. This was because the efforts for curriculum reorganizing and teaching methods improvement were done. Third, we could not find significant recognition difference about the perception of the needs for job performance and work level. That was because accredited and non-accredited program were not dealed seperately. The conclusions of this study are summarized as follows: First, The efforts for analyzing job competence of industry and reflecting the program curriculum are needed on the accredited program for engineering education. Second, Government should make the incentive policy about the companies which give some merits to the accreditation graduates, and monitor constantly their real working. Third, in order that the accreditation results can be trustful on staff recruiting or school choosing, accreditation should make outcome-based-evaluation which guarantees competence of graduates.

This study started to examine the understanding and perception of 'disabled people' and 'non-disabled people', one of the dichotomous elements in the 21st century social integration era. In particular, for the analysis, Q-methodology, which should respond based on the respondent's inner self and perception, was used. For the analysis, 32 Q-statements were secured, and as a result of targeting 20 P-sample respondents, three types were derived as follows. In , statements such as 'A correct awareness of disability is necessary' and 'Disability can occur to anyone' are emphasized, so it was named 「Correct Perception Emphasis Type」. emphasized 'The life of the disabled is not easy' and 'The disabled need an opportunity to participate in society' and was named 「The Life of the Disabled Understanding Type」. emphasized statements such as 'Economic support is necessary for the disabled' and 'The welfare budget for the disabled must be sufficiently secured', and was named 「Institutional Support Emphasis Type」. Therefore, in addition to the necessity of correct recognition of disability and disability in our society, we expect this study result is to be priming water for improving the recognition of the disabled.

This study tries to investigate the relationship between physical perception and creative thinking of dancers by dance imagery training programs. The inner imagery and the external expression of dancers are a divergent expression process of autosuggestion, and substantiate the relationship between physical perception and creative thinking. The key point consists in the active thinking process of problem recognition and problem solving by imagination, and means a new perceptivity and the communication capability. Dance imagery is a perception training based on the integration principle of body and soul, and so dancers should create a new approach of communication through the diversity of wide inner imagination and the active thinking of external expression.

Background: This study was aimed at investigating the perception of social network service (SNS) users regarding dental office visits and determining the proportion of dental SNS users among general SNS users. Methods: We surveyed 177 adults using SNSs. Dental SNS characteristics were classified into information provision, interaction, recency, reliability, and interest, and the recognition level of each area was surveyed on a 5-point scale. The total number of items was 17, including three information provision, three interaction, four recency, four reliability, and three interest items. Results: Among the five domains, the recognition level was the highest for reliability (3.51 points) and the lowest for interest (2.94 points). Among the 17 items, the recognition level was the highest for "Educational information provided by dental SNS is valuable" at 3.60 points, "Dental SNS educational video is useful for information sharing and dental knowledge improvement" at 3.53 points, and "The perceived educational information of dental SNS is reliable" at 3.51 points. Participants in their 20s and 30s had higher scores for being up-to-date (3.33 and 2.88 points, respectively) and reliability (3.59 and 3.09 points, respectively) than those in their 40s or older. The recognition level of all areas of dental SNS characteristics was significantly higher for experienced dental SNS users than for nonexperienced ones. Conclusions: The results of this study suggested that dental institutions should consider ways to utilize SNS for patient management and education and that dental SNS-related contents should contain educational and reliable information to help SNS users manage their oral health.

This study examined the ideal type of a man that women prefer and the recognition of men for their own appearance management with the rise of the importance for appearance management today. The prerequisite which matters most in time of considering a man as a date of love predominantly was centered on education, and the prerequisite which goes first among the rest in time of judging a man as the mate of marriage was undoubtedly his financial status. It is regarded that as for a date of love the visual image or the specialty other than the conditions in reality mattered most, and concerning a mate in marriage the actual financial conditions had the priority. When a man is evaluated, the percentage of appearance took the highest rate of 60~80%, and in his appearance, the general harmony was considered as the most important factor. As for the recognition of men for their appearance management, women tend to have an affirmative realization for managing their own appearance in general, and the reason was they believe that the way men take care of their own appearance belongs to personal free will. The perception for a man with a decent appearance was very positive, and the ground for this was that once the appearance looks handsome, he seems gorgeous. The recognition for men's cosmetic surgery showed the affirmation over the average, and an opinion that the settlement of personal appearance complex will help them out emerged as the ground for this affirmation, and so it is regarded that the aesthetic surgery of today and the perception for men's appearance management have become universal phenomena unlike former days with the reflection of visualization of the external visual and lookism shown from various media.
