This study proposed two multisensor fusion methods for segment-based image classification utilizing a region-growing segmentation. The proposed algorithms employ a Gaussian-PDF measure and an evidential measure respectively. In remote sensing application, segment-based approaches are used to extract more explicit information on spatial structure compared to pixel-based methods. Data from a single sensor may be insufficient to provide accurate description of a ground scene in image classification. Due to the redundant and complementary nature of multisensor data, a combination of information from multiple sensors can make reduce classification error rate. The Gaussian-PDF method defines a regional measure as the PDF average of pixels belonging to the region, and assigns a region into a class associated with the maximum of regional measure. The evidential fusion method uses two measures of plausibility and belief, which are derived from a mass function of the Beta distribution for the basic probability assignment of every hypothesis about region classes. The proposed methods were applied to the SPOT XS and ENVISAT data, which were acquired over Iksan area of of Korean peninsula. The experiment results showed that the segment-based method of evidential measure is greatly effective on improving the classification via multisensor fusion.

Purpose: This study was designed to explore the stage distribution of subjects according to stages of change for exercise and to identify factors that could discriminate subjects in various stages. Methods: The sample consisted of 182 subjects who had metabolic syndrome. The instruments used in this study were the stage placement instrument for exercise, the metabolic syndrome knowledge and metabolic syndrome health belief scale, and the metabolic syndrome exercise self efficacy scale. Data were analyzed using chi-square, ANOVA, and discriminant analysis by using the SPSS 19.0 program. Results: For exercise stages, exercise efficacy, occupation, and exercise benefit showed high standardized canonical discriminant function coefficients. Subjects in precontemplation/contemplation stage for exercise were more likely to have occupations, had less exercise efficacy and exercise benefit than those in other stage. Conclusion: This study implies that the level of exercise efficacy and exercise benefit of subjects in precontemplation/contemplation stage need to be enhanced in developing exercise program incorporating the stage of change for metabolic syndrome patients.

Duration of the preceding vowel is known to vary as a function of the (phonological or phonetic) voicing feature of the following consonant. This study raises a question against this general belief. A spectrographic experiment using 14 Korean obstruents (three sets of stops: /p, p', $p^h$/, /t, t', $t^h$/, /k, k', $k^h$/; one set of affricates: /c, c', $c^h$/; one set of fricatives: /s, s'/) reveals that (1) phonetic voicing in the intervocalic lax consonants /p, t, k, c, s/ has nothing to do with the duration of the preceding vowel; (2) vowel length is significantly shorter before tense consonants than before their lax cognates while tense consonants are significantly longer than their lax cognates. Importantly, Korean obstruents are all phonologically voiceless. Therefore, the voicing feature is rejected as the cause of preconsonantal vowel shortening in Korean both phonetically and phonologically. It is suggested that the temporal phenomenon is basically a kind of physiologically-motivated coarticulation though it is restricted by the phonology of a given language. To meet this assumption, the feature voicing should be replaced with the feature tenseness as the cause, which will enable us to explain the temporal phenomenon on the same basis irrespective of language.

Bridge - Treading was a flok festival that was held on the night of the 1st full moon of the lunar new years. Men and women, both young and old, took pan in it in the belief that crossing a bridge, or bridges, back and forth, the same number of times as the number of years they were old, on this night would prevent all types of leg and foot ailments from occurring throughout the coming year. The practice was carried on mainly around the Seoul central region of Korea. Though it has now largely disappeared, it has been reatores in the Yeoju area. According to the Korean almanac and other chronicles, it was once practiced throughout the land. It is in the preserved was brige-treading festival of yeoju, however, that both the original form, transmission, and function are clarified and brought to light. In this regard, when compares to similar festivals of other region such as Songpa and Kwacheon, it is found that of Yeojo has a special characteristic. Accompanied by folksongs, music, and dance, this was not a religions festival in the strict sense, but rather an annual custom filled with mirth and merriment that formed an integral part of Korean folk culture.

The faith in St. Mary of Guadalupe is supposed to be concerned not as reminiscence of historical events or legends, but organic product of having nowness. It's an organism that can not be stay in a fixed type. From the perspectives of syncretism the coexistence of heterogeneous elements (Symbiosis) between Catholicism and Aztec's religion has been changed constantly depending on the necessity and function of the subjects who have dreamed the social integration. It's fundamentally clear that the faith in St. Mary of Guadalupe is still valid phenomenon in the modern Mexican society and that the faith is an aspect of popular catholicism which includes the remaining elements of the religion of the Aztecs. This is to understand the meanings of the perception of the contemporary mexicans on the phenomenon for the faith in St. Mary of Guadalupe. Through in-depth interviews, it is revealed that a high rate of sharing of the information does not mean the proportional acceptance of the history. It's a interesting point to see that the mexicans consider the faith in St. Mary of Guadalupe catholic belief, having a feeling of strong tie between themselves and the Aztec's religion. In spite of the historical conflicts over the veracity of St. Mary of Gaudalupe, the majority of the contemporary mexicans consider the faith positive element to consolidate the nationality and socio-cultural identity of $M{\acute{e}}xico$ against the socio-political and ethnic conflicts in the Mexican Society.

Background: Subjects with frozen shoulder (FS) might not be comfortable with vigorous physical therapy. Clinical trials assessing the effect of graded motor imagery (GMI) in FS are lacking. The aim of this study was to determine the effect of GMI as an adjunct to conventional physiotherapy in individuals with painful FS. Methods: Twenty subjects aged 40-65 years having stage I and II of FS were randomly divided into two study groups. The conventional physiotherapy group (n = 10) received electrotherapy and exercises while the GMI group (n = 10) received GMI along with the conventional physiotherapy thrice a week for 3 weeks. Pre- (Session 1) and post- (Session 9) intervention analysis for flexion, abduction, and external rotation range of motion (ROM) using a universal goniometer, fear of movement using the fear avoidance belief questionnaire (FABQ), pain with the visual analogue scale, and functional disability using the shoulder pain and disability index (SPADI) was done by a blinded assessor. Results: Statistically significant difference was seen within both the groups for all the outcomes. In terms of increasing abduction ROM as well as reducing fear of movement, pain, and functional disability, the GMI group was significantly better than control group. However, both groups were equally effective for improving flexion and external rotation ROM. Conclusions: Addition of GMI to the conventional physiotherapy proved to be superior to conventional physiotherapy alone in terms of reducing pain, kinesiophobia, and improving shoulder function for stage I and II of FS.

Mehndi, becoming a kind of body fashion in western advanced countries nowadays, is a exquisite, classical fashion form sublimated to traditional faith, medicine and designing art. As one of the cultural arts, especially transmitted by women, a individual tradition of the way how to do the mehndi and the design has been handed down from one culture to another over a thousand of years and it is extensively using in many area, all around world today. Mehndi was used as preparing for special events or celebrations in India, Africa, Central Asia in order to pray for happiness, good luck and calm hart 5000 years ago. Especially, it is concerned with romantic love or a wedding and takes important part of a traditional wedding reception and bride adorning in the culture of Hindu or Islam. In addition to adorning skin, mehndi has various symbols, meaning, function, that is, as a speechless language, in several cultures, it has common meaning such as attraction, protection, celebration. The design of mehndi has been in harmony with the figure, colors, skin types of the dress or the ornament. According to the region, religion, design, mehndi is divided into the design of India and Morocco mostly. Indian design mainly shows flowers and paisley pattern, people widely recognize this design to celebrate and adorn bride in wedding ceremony, still apply mehndi the present time. Moroccan mehndi design, representing North Africa, characterized a bold geometrical figure which stands for belief in living under the protection from supernatural power. Through the understanding of these various meaning, function, symbolism of the design, adorning their body, the current general public use mehndi as not only aesthetic means but also another self expression.

The prosthodontic treatment of severely resorbed edentulous patients has been one of the frustrating areas due to extensive loss of tissues. The integrated neuromuscular balance among tongue, lip, and cheek is compromised. The retention, stability, and support are the three major factors to influence the clinical outcome. Fish described a denture as having three surface, with each surface playing an independent and important role in the over all fit, stability, and comfort of the denture. He recommended that the polished surface should be a series of inclines so that pressure from muscular activity will retain dentures. Within the denture space there is an area that has been termed the neutral zone. The neutral zone is that area in the mouth where, during function, the forces of the tongue pressing outward are neutralized by the forces of the cheeks and lips pressing inward. According to Jacobson and Krol, neuromuscular control interacts to provide retention and the relationship of polished surface of denture base to the surrounding muscular structure of orofacial capsule facilitates the stability and retention. This neutral zone concept has been demonstrated with various modification by a number of authors. The theory used to develop the denture base contours is based on the belief that the muscle should functionally mold not only the border but the entire polished surface. Lott and Walsh reported the clinical success on complete mandibular dentures with application of neutral zone concept. A number of studies demonstrated that denture stability and retention are more dependent on correct position of the teeth and correct contour of external surfaces of the denture in a severely resorbed alveolar ridge. This article presents a prosthodontic approach to treatment of a edentulous patient using neutral zone technique to improve the retention and stability of the prosthesis.

Due to the discontinuous nature of uncertainty quantification in conventional evidence theory(ET), the computational cost of reliability analysis based on ET model is very high. A novel ET model based on fuzzy distribution and the corresponding combination rule to synthesize the judgments of experts are put forward in this paper. The intersection and union of membership functions are defined as belief and plausible membership function respectively, and the Murfhy's average combination rule is adopted to combine the basic probability assignment for focal elements. Then the combined membership functions are transformed to the equivalent probability density function by a normalizing factor. Finally, a reliability analysis procedure for structures with the mixture of epistemic and aleatory uncertainties is presented, in which the equivalent normalization method is adopted to solve the upper and lower bound of reliability. The effectiveness of the procedure is demonstrated by a numerical example and an engineering example. The results also show that the reliability interval calculated by the suggested method is almost identical to that solved by conventional method. Moreover, the results indicate that the computational cost of the suggested procedure is much less than that of conventional method. The suggested ET model provides a new way to flexibly represent epistemic uncertainty, and provides an efficiency method to estimate the reliability of structures with the mixture of epistemic and aleatory uncertainties.
