This paper presents an extensive analysis of the short term, unsteady wind loading on a low-rise building. The building is located in a rural environment and only the specific situation of wind flow orthogonal to the long face of the structure is considered. The data is analysed using conventional analysis and less traditional methods such as conditional sampling and wavelet analysis. The nature of the flow field over the building is found to be highly unsteady and complex. Fluctuating pressures on the windward wall are shown to a large extent to be caused by the fluctuations in the upstream flow, whereas extreme pressures on the roof are as a result of high intensity small scale flow structures. On the roof of the building a significant amount of energy is shown to exist at frequencies above 1 Hz.

In this work, we investigate the quantum effects exhibited from ultra-thin GAA(gate-all-around) Nanowire FETs for Sub 14nm Technology. We face designing challenges particularly short channel effects (SCE). However traditional MOSFET SCE models become invalid due to unexpected quantum effects. In this paper, we investigated various performance factors of the GAA Nanowire FET structure, which is promising future device. We observe a variety of quantum effects that are not seen when large scale. Such are source drain tunneling due to short channel lengths, drastic threshold voltage increase caused by quantum confinement for small channel area, leakage current through thin gate oxide by tunneling, induced source barrier lowering by fringing field from drain enhanced by high k dielectric, and lastly the I-V characteristic dependence on channel materials and transport orientations owing to quantum confinement and valley splitting. Understanding these quantum phenomena will guide to reducing SCEs for future sub 14nm devices.

The purpose of this study was to analyze the effects of both social-status and mode of stimulus-presentation on children's empathic behavior, where empathy is defined as either the comprehension and recognition of an affective state in stimulus persons (others) or the empathic response to that perception. Middle-and lower-class kindergarten children were presented with a series of either short-sentence stories or short-pictorial stories. The subjects were asked to indicate how the child in each situation felt by selecting a "happy", "sad", or "angry" face to complete the picture accompanying each story. Immediately following the first question, children were asked to state verbally how the child in the picture might feel. The main results were (1) The mean empathy scores for the comprehension and recognition of an affective state in others and the empathic response to that perception was higher in middle-class children than in lower-class children. (2) There were differences in empathy scores to the three affective situations, i.e. the mean score for both happiness and sadness was significantly greater than for aggression, and (3) The empathy scores in the pictorial-stories were greater than in the sentence-stories.

In this paper, we intend to establish the judgement of electrical fire through analysis of PT(Potential Transformer) using the power installation. The columnar structure and the void generated by abrupt heat grew at the tenter of boundary-face on the metallurgical microscope analysis. The detection of OK lines was confirmed by EDX(Energy Dispersive X-ray spectroscopy) as melting and recombination due to the layer-short of the wiring. We found that the thermal-weight decrease occurred at 300$^{\circ}C$ in case of being the thermal-deterioration on the base of the result that analyzed the insulated-materials by using TGA, and the thermal reaction limited-value of PT insulator was about 300$^{\circ}C$ on the DSC curve. As this analysis, we confirmed what the layer-short appeared in the wiring of PT.

Discussion of facial image of the movie starts is recognized as an art movie that started from silent film period. Critical discussions on the facial image initiated with the emergence of 'close-up' are performed in the context to claim the superiority of close-up format. Therefore, the trend of critical discussion on the facial image differs from two perspectives to perceive close-up in this era. The first perspective is to privilege both face and close-up since close-up is recognized as the unique tool to realize the face considering close-up as the independent body to have new aesthetic feasibility of the movie. The second perspective is to consider close-up as one of the plots in the movie language to complete its narration. In this case, it is perceived as just a short, which has no differentiation from the others, as long as the facial image does not interfere the completeness of the narration, because the characteristics of close-up to highlight the subject more than the other short is not recognized as the unique form to complete the movie, and because it has the meaning only when the subject and the format aim to maintain the completeness of the narration.

1. Objectives: We aimed to derive constitutional facial characteristics with front and side picture of the people in this study 2. Methods: Through November 2007 to July 2009, we obtained front and side face photograph data of 715 male/female constitution confirmed subjects within the age range of 10-80 from 19 oriental medical facilities in the country. According to sex, we divided the subjects into two groups, real constitution group and non-constitution group. We analyzed significant variables of distance, angle and ratio of facial point through unpaired T-test. 3. Results: There are different significant variables according to Sasang Constitution and even though they are much different between sex, the interpretation of the meaning of those variables are similar with the written characteristics of ancient Writing. The face size of the Taeeumin is bigger than that of the non-Taeeumin, and especially they have long length from mouth to mandible angle. Soeumin have small jaw area, long philtrum and narrow facial feature like egg. Soyangin has developed forehead and glabella, short jaw, long eye side. Taeyangin has developed forehead, weak nose especially side end of nose, long eye side. 4. Conclusions: Sasang Constitutional facial characteristics are different between man and woman but there are much similarity with the facts as known on the interpretation of significant variables characteristics.

Image warping is a technology to transform input images to be suitable for given conditions and has been recently utilized in changing face shape of characters in the field of movies or animation. Mesh warping which is one of warping methods that change shapes based on the features of face forms warping images by forming rectangular mesh groups around the eyes, nose, and mouth and matching them 1:1. This method has a problem in the resultant images are distorted in the segments of boundaries between meshes when there are errors in mesh control points or when meshes have been formed as many small area meshes. This study proposes a triangle based image interpolation technique to minimize the occurrence of errors in the process of forming natural warping images of face and process accurate results with a small amount of arithmetic operation and a short time. First, feature points that represent the face are found and these points are connected to form basic triangle meshes. The fact that the proposed method can reduce errors occurring in the process of warping while reducing the amount of arithmetic operation and time is shown through experiments.
