This article addresses the problem of measuring a joint agreement between multiple raters and a standard set of responses. A new agreement measure based on Um's approach is proposed. The proposed agreement measure is used for multivariate interval responses. Comparison is made between the proposed measure and other corresponding agreement measures using hypothetical data set.

Objectives : This paper was for studying the features of sleep according to Sasang Constitution and to be helpful to make a diagnosis Sasang Constitution. Using the result of this study, it will be helpful to diagnose a Sasang constitution. Methods : There were 610 patients(258 men, 352 women) who answered questionnaire and were diagnosed by the Sasang Constitution Specialist at Constitutional Clinic of Dongguk Bundang Oriental Hospital. Using the response of questionnaire and several statistical techniques such as homogeneity test and multiple comparison, we tried to find the characteristics of each constitution depending on its sleep behaviors. 3. Results : As a result of the analysis of questionnaire, Soeumin has many dreams in comparison with other constitution(p<0.01). Taeumin and Soyangin have a few dream in comparison with Soeumin(p<0.01). Taeyangin has a characteristic that 'he is not drowsy comparatively, he awakes easily, he is not drowsy if it is cold, he is not drowsy and has many dreams if he has many stress.(p<0.01) Taeumin has a characteristics that 'he has a few dream in ordinary times'(p<0.01).

Multiple aneurysms at the same cerebral arterial branching site are rare, and have been mainly described in a few case reports in comparison with other intracranial multiple aneurysms. Most reported locations of the same artery where multiple aneurysms developed were internal carotid artery and anterior communicating artery. We experienced a very rare case of multiple aneurysms arising at the same bifurcation site of the middle cerebral artery. Only one case like this has been reported previously in the literature. We discussed the preoperative diagnosis and surgical management of such condition.

As manufacturing industries become globalized, product design affects every area of organization. The design sets the goals for a number of different departments, so if it fails to effectively communicate these goals, the entire organization is less efficient. In addition, To communicate clearly, the design must represent a product that meets its technical specification. GD&T (Geometric Dimensioning and Tolerancing) is one of the most important factors, which has an effect on efficiency of manufacture system, in designing products. However, most of designers in different industries are prone to ignore the importance of GD&T. To analyse the importance of GD&T compliance with international standards for design drawing, a comparison analysis of the difference between two methods, composite profile control and multiple single segment profile control, is performed on three different cases and suggests how it used to be more suitable. Composite profile tolerance is specified by a dual feature control frame that has one profile symbol specified with two lines of tolerance information. Whereas a multiple single segment profile control is when two or more single segment profile callouts are used to define the location and/or orientation and/or size and/or form of a part feature. In this study, the following results will be provided : a clear definition and an obvious difference of the tolerance zone, datums and datums sequence and minimization of tolerances. On this study, composite profile tolerance and multiple single segment profile tolerance were discussed. Next steps of research will consist on reaching more accurate results for profile control. Further research will be focused on dealing with the remaining 14 symbols of GD&T.

The purpose of this study was to examine: (1) the relationships among internalization of sociocultural attitudes toward appearance, body comparison, and body dissatisfaction in adolescent girls; and (2) whether or not body comparison mediates the relationship between internalization of sociocultural attitudes toward appearance and body dissatisfaction. The participants consisted of 291 girls from fifth through ninth grades. The data were collected by means of questionnaires given in classroom settings. The findings are as follows: there are significant bivariate correlations among internalization of sociocultural attitudes toward appearance, body comparison, and body dissatisfaction. Furthermore, body comparison partially mediates the relationship between internalization of sociocultural attitude towards appearance and body dissatisfaction. These results seem to indicate that the idea that there are multiple standards of beauty and individuality for every person should be promoted, and this in turn could lower the risk of body dissatisfaction among adolescent girls.

Spatial correlation is a result of insufficient antenna spacing among multiple antenna elements, while temporal correlation is caused by Doppler spread. This paper compares the effect of spatial and temporal correlation in order to investigate the performance of multiuser scheduling algorithms in multiple-input multiple-output (MIMO) broadcast channels. This comparison includes the effect on the ergodic capacity, on fairness among users, and on the sum-rate capacity of a multiuser scheduling algorithm utilizing statistical channel state information in spatio-temporally correlated MIMO broadcast channels. Numerical results demonstrate that temporal correlation is more meaningful than spatial correlation in view of the multiuser scheduling algorithm in MIMO broadcast channels. Indeed, the multiuser scheduling algorithm can reduce the effect of the Doppler spread if it exploits the information of temporal correlation appropriately. However, the effect of spatial correlation can be minimized if the antenna spacing is sufficient in rich scattering MIMO channels regardless of the multiuser scheduling algorithm used.

Since the variations of illumination, the irregular changes of human shapes, and the partial occlusions, multiple person tracking is a challenging work in computer vision. In this paper, we propose a graph clustering method based on spatio-temporal information of moving objects for multiple person tracking. First, the part-based model is utilized to localize individual foreground regions in each frame. Then, we heuristically leverage the spatio-temporal constraints to generate a set of reliable tracklets. Finally, the graph shift method is applied to handle tracklet association problem and consequently generate the completed trajectory for individual object. The extensive comparison experiments demonstrate the superiority of the proposed method.

Multiple-model speech recognizer has been shown to be quite successful in noisy speech recognition. However, its performance has usually been tested using the general speech front-ends which do not incorporate any noise adaptive algorithms. For the accurate evaluation of the effectiveness of the multiple-model frame in noisy speech recognition, we used the state-of-the-art front-ends and compared its performance with the well-known multi-style training method. In addition, we improved the multiple-model speech recognizer by employing N-best reference HMMs for interpolation and using multiple SNR levels for training each of the reference HMM.

The purpose of this study was to suggest ways on reducing the cooling and heating energy cost of the officetel building with the multiple glazing windows according to Life Cycle Costing. This study consisted of an hour-by hour energy simulation program and further data from the EnergyPlus V1-2-2 to the four pane type windows that were applied with 2 low-e polyester film and krypton gas to the officetel model building. It was determined that the four panes type windows that had 2 low-e polyester film and krypton gas applied to, them showed a cooling and heating cost reduction over traditional double glazed windows that were filled with air. According to this study, as well as the information from chart 4.5 and the LCC it was determined that the present value of the four panes of windows that had 2 low-e polyester film and krypton gas applied to them showed. a 11.4% reduction in heating and cooling in comparison to the traditional double glazed windows that were filled with air.
