  • According to the cognitive science research, the interaction intent of humans can be estimated through an analysis of the representing behaviors. This paper proposes a novel methodology for reliable intention analysis of humans by applying this approach. To identify the intention, 8 behavioral features are extracted from the 4 characteristics in human-human interaction and we outline a set of core components for nonverbal behavior of humans. These nonverbal behaviors are associated with various recognition modules including multimodal sensors which have each modality with localizing sound source of the speaker in the audition part, recognizing frontal face and facial expression in the vision part, and estimating human trajectories, body pose and leaning, and hand gesture in the spatial part. As a post-processing step, temporal confidential reasoning is utilized to improve the recognition performance and integrated human model is utilized to quantitatively classify the intention from multi-dimensional cues by applying the weight factor. Thus, interactive robots can make informed engagement decision to effectively interact with multiple persons. Experimental results show that the proposed scheme works successfully between human users and a robot in human-robot interaction.

  • Purpose: The purpose of this study was to determine the relationship between assessed pain, functional status, and emotional status in elderly women with dementia. Methods: The method was a descriptive correlational design. Subjects were sampled from 75 elderly women with dementia who were resident in nursing home. and their pain, functional status(physical function, cognitive function), emotional status(depression, agitation) were measured. The collected data were analyzed for correlations between pain and functional status and for emotional status using the SPSS 11.0 statistical program. Results: The pain degree of the aged women in dementia were as follows; between 0 and 27 points, average 4.04 points, which was a possible point extent. Looking at the grades in detail items, the wry face expression was shown highest, an average of 0.84 points. The relation with cognitive function was(r=-.259, p<.025) a minus relation. And the relation with physical function was (r=.406, p<.001) a plus one. The relation with depression was (r=.462, p<.001), plus one. And (r=.592, p<.001) a plus relation was found with agitation. Conclusion: Pain is associated with impaired functional and emotional status. Major efforts are needed to improve nursing assessment and management of pain in this cognitive impaired population.

  • Cancer is a major health problem in Oman. It is reported that cancer incidence in Oman is the second highest after Saudi Arabia among Gulf Cooperation Council countries. Based on GLOBOCAN estimates, Oman is predicted to face an almost two-fold increase in cancer incidence in the period 2008-2020. However, cancer research in Oman is still in its infancy. This is due to the fact that medical institutions and infrastructure that play central roles in data collection and analysis are relatively new developments in Oman. We believe the country requires an organized plan and efforts to promote local cancer research. In this paper, we discuss current research progress in cancer diagnosis using machine learning techniques to optimize computer aided cancer detection and classification (CAD). We specifically discuss CAD using two major medical data, i.e., medical imaging and microarray gene expression profiling, because medical imaging like mammography, MRI, and PET have been widely used in Oman for assisting radiologists in early cancer diagnosis and microarray data have been proven to be a reliable source for differential diagnosis. We also discuss future cancer research directions and benefits to Oman economy for entering the cancer research and treatment business as it is a multi-billion dollar industry worldwide.

  • Health behavior constitutes the single most important factor in an individual's health maintenance program. Pender's health promotion model emphasizes the positive aspects of health-seeking behavior hut omits some negative ones. Although Pender's work does include the concept of barriers, the main focus is upon health habits rather than upon the interaction between the consumer and the health care system. Therefore, since individuals actually do face many barriers in their health-seeking behavior, the present study deals with negative concepts-the barriers to health and healthy behavior. For this reason the expression health-seeking behavior was chosen over health promotion. In conclusion, the results show that barriers to health-seeking behavior are causal factors that could explain and predict the health-seeking behavior of middle life women. Midlife women shows that they have barriers to health-seeking behavior especially in inconvenience, cost, healthcenter site-related problem, relationship, fear. These findings suggest the need to develop a nursing strategy to improve the empowerment of self-determination in middle-aged women. Consequently, a goal of nursing care for middle-aged women should be to help them pursue health care with a greater degree of self-sufficiency.

  • This study is on the various style and characteristics of mask, and was performed empirically by reviewing the related materials such as the literature, precedent studies, fashion works, and home and foreign fashion magazines. As a result of the study, the style of mask in the modern fashion is roughly categorized by full-covered style, half-covered style, and over-half-covered style which is covered over 50% of a face. And, mask is utilized on a hat or a dress all over, or is produced by a elaborate makeup. Mask with lots of variation has three big characteristics, which are sense of disguise, sense of ornamentation, sense of grotesquery. First, sense of disguise means deviation or tool of affectation instead of cultural standard norm through transforming or masquerading as an imagery person or animal in ancient myths, famous artistes, etc. It could be developed to express a designer's identity. Second, mask decorated with various styles and materials has sense of ornamentation, which means natural human desire of expression for beauty, and at the same time human mind longing for experience a fantastic and ideal inner world being deviated from the present world even indirectly. Third, ignoring the original format of eyes, nose, and mouth, using extraordinarily various techniques such as distortion, extreme, exaggeration, concealment, or combining with animal images, mask has sense of grotesquery inducing humor and horror simultaneously.

  • As a applied art, Architecture is a synthetic art for dwelling and settlement. It has started with the origin of the human. and Artistical-technological indicator, include not only materiality but also immateriality such as history and society. After 20C, various categories of thinking is a undergoing rapid change. especially, beginning in 1900, The intrinsic value of "Fine Art" had lost their competitive power in the face of industrial revolution's mass production. and it has been displaced by a "new concept", such as a conveyance of meaning or rational way of thinking. This change means free from the tradition and custom of a past. for that reasons, Due to the nature of applied art, it always include design symbolism and designer's thinking is mainly processed in their own system of thinking. Symbolism for the art was distinguished from a general concept by the connotative meaning that called "the dual image". Therefore, at the start, this study will define about design and symbolism with a architecture as a applied art. then, Analysis the expression tendency of the contemporary architecture and modification. as a result, It aim to systematize mapping process and suggest the classification of various visual cue.
