In this paper, we present a new approach to detect and recognize human face in the image from vision camera equipped on the mobile robot platform. Due to the mobility of camera platform, obtained facial image is small and pose-various. For this condition, new algorithm should cope with these constraints and can detect and recognize face in nearly real time. In detection step, ‘coarse to fine’ detection strategy is used. Firstly, region boundary including face is roughly located by dual ellipse templates of facial color and on this region, the locations of three main facial features- two eyes and mouth-are estimated. For this, simplified facial feature maps using characteristic chrominance are made out and candidate pixels are segmented as eye or mouth pixels group. These candidate facial features are verified whether the length and orientation of feature pairs are suitable for face geometry. In recognition step, pseudo-convex hull area of gray face image is defined which area includes feature triangle connecting two eyes and mouth. And random lattice line set are composed and laid on this convex hull area, and then 2D appearance of this area is represented. From these procedures, facial information of detected face is obtained and face DB images are similarly processed for each person class. Based on facial information of these areas, distance measure of match of lattice lines is calculated and face image is recognized using this measure as a classifier. This proposed detection and recognition algorithms overcome the constraints of previous approach [15], make real-time face detection and recognition possible, and guarantee the correct recognition irregardless of some pose variation of face. The usefulness at mobile robot application is demonstrated.

In the early Joseon when royal authority was not still firmly established, King Taejong, or Lee Bang Won tried to make their political position guaranteed through relationships with Ming, making efforts to develop relations with the Chinese nation positively. This political orientation towards Ming by of the king Taejong was also clearly reflected in the settlement of official uniform in the early Joseon, which can be described as follows. Gaoming(誥命), Yinxin(印信) and Mianfu(冕服) granted by Ming for the first time since the foundation of Joseon suggested that the Chinese nation recognized the formal settlement of Joseon dynasty and the inauguration of King Taejong. presumedly, the grants played a critical role in the firm establishment by King Taejong of his royal authority under unstable political conditions. Under the reign of King Taejong, Joseon tried to abolish ancient regime and, instead, accept systems and institutions of Ming as it maintained smooth relations with the Chinese nation. King Taejong whose royal authority was locally deemed lack in legitimacy and morality wanted to receive the moral recognition of his reign. So the monarch tried to not only strengthen his authority, but also take in advanced culture and civilization through submissive diplomatic relations with Ming. This was a practical diplomatic strategy that was clearly discriminated from toadyism. It was a policy towards Ming, pursuing substantial national benefit. Therefore, official uniform system under the reign of King Taejong should be understood accordingly.

Purpose: Healthcare is on the whole a personal and critical service that consumer's use, whereas hospitalization is as a rule painful, because nature nurtures and Sun Light Luminosity for healthcare settings is considered healing. The performance and design of climate responsive buildings such as AKU requires a detailed study of attributes of climate both at micro as well as macro level. The therapeutic value of contact with nature through window view, greenery and landscape is calculated there. Method: A two prong strategy is been devised for this article, at micro level three typical morphologies are analysed by creating same environment of neighboring building on sun shading chart, radiation and temperature range. Since the analysis of local climate helps to determine the design strategies for hospital Healing Environment which is suitable for Karachi climate; in order to track the macro climatic behaviour, a considerable analysis of psychometrics chart for AKU Karachi are designed on Climate Consultant (CC) and analysed by Machine Learning. Climate Consultant proposes different design strategies suitable for Karachi. And on the other hand time wise illumination sources for clinical area which are then measured on psychrometric chart- according to singular space: multi patient admission, secondly: acute ambulatory ward, and tertiary: multi windowed space according to the mushrabiyah and sky light pattern. Result: Our findings support the hypothesis that windowed wall is 75-80% more healing wall; an accelerated evidence was found for healing at macro level if the form of the hospital is designed according to the climatologically preferences, whereas at micro level: the light resource becomes the staff attentiveness determinant. In Conclusion evidence was provided that the actual form of luminosity results consequently in satisfaction while light entering from several set of windows and other sources might be valued if design according to the healing environment. The data added on the sun shading chart to calculate rays entraining into space in patient room equal to 124416.21 Watts/ meter $m^2$ is calculated as precise healing rate-and is confirmed by questionnaire from patients belonging from each clinical stage having different illnesses.

The purpose of this study is to determine values and value changes of the four year course nursing college students. The survey was conducted against 262 students of the nursing college, from all classes (freshman, sophomre, junior and senior). This study was conducted during the period of first through 15th of December 1984 in accordance with the L.V. Gordon's“Survey of Interpersonal Values (SIV)”. The results of the study were as follows: 1. Those nursing students surveyed show that conformity (16.32) took the highest place and reconition (10.21) lowest in the general value orientation. In accordance with the Cordon's SIV, those of other woman college students indicate 14%ile-65%ile, respectively. 2. Changes in values by class indicate that freshman, sohpomore and senior students showed similar Pattern but junior students showed significantly lower than other classes. The difference should be considered on the basis of statistics (p <.05). Accordingly, the hypho-thesis 1 of this study has been supported. 3. Significant variation has been shown by each class in each factor such as support, conformity, independence and benevolence but no variation has been indicated in leadership and recognition. 4. There was difference in values between higher class (jounior and senior) students with clinical experience and starting class (freshman and sophomore) students without clinical experience. The study indicates the values of higher class. students is lower than that of starting class. students (P <.05). Therefor, the hyphothesis 2 of this study has been supported. 5. There was no significant difference in values between entering students and graduating students (p<.05), Thus, the hyphothesis 3 of this study has been rejected. The results of the finding of the study show that there is no positive influence in forming the values. for the students. Therefore, it is concluded that new strategy and special educational program should be established for formulation of the right values for the nursing college students.

This article was written with two purposes in mind. The first purpose was to introduce clothing and textile community who may not be familiar with Multidimensional Scaling(MDS) with usefulness of the new technique in the area of fashion merchandising. The second purpose was to present the results of an empirical study on brand image utilizing MDS and its related technique as the main analysis tools. The main objective of the empirical study was to gain a better understanding of consumer's brand image by relating differences in perception and attributes of clothing in women's ready-to wear market. For this empirical study, the ten brands and the fifteen attributes of clothing were chosen. The questionnaire consisting of questions asking about the similarity and attributes of clothing between selected brands was administrated to 185 career women during summer in 1989. Data were analyzed cluster analysis, and KYST and PROFIT in MDS program. The results were as follows: 1. The similarities data for the ten selected brand by using KYST program of MDS drawed the perceptual map. The results of this perceptual map showed that the selected brand were grouped into three clusters. 2. In order to get a somewhat objective view of which attributes consumers are attributing to each brand, PROFIT program was used. As a result, it was revealed that assortment depth / width, price, youth-oriented style, possibility of various social activity were significant attributes in consumer's brand choice rather than physical attributes of clothing such as quality or durability. This may imply that consumer orientation in rapidly changing environments of women's apparel market was its basic idea, and the focus of all fashion merchandising activities was put on need's and the response of consumer group who are the object of the target. Implicating for future research as well as for strategy of brand positioning were also suggested.
