Europeans are much more rigid in their thinking on robots and especially have a negative view on robots as peers since they regard robots as labor machines. Recently, Korea invented several educational robots as peer tutors. Therefore, study was needed to determine the difference in cultural acceptability for educational robots between Korea and Europe (Spain). We found that Europe seems to be much more rigid in its thinking on robots and especially has a negative view on educational robots. Korean parents have a strong tendency to see robots as 'the friend of children,' while on the other hand, European parents tend to see educational robots as 'machines or electronics'. Meanwhile, the expectation of children on educational robots showing identification content was higher in Europe than in Korea since European children are familiar with costume parties. This result implied that we may find a Korean market for educational robots earlier than a European market, but European children will be eager to play with educational robots even though their parents have a negative view of them.

Purpose Obesity goes on increasing rapidly because of the change of dietary life, various stresses and convenience of life, that cause heart disease, diabetes mellitus, hypertension, fatty liver, arteriosclerosis these days. As obesity is disease, I think there will be constitution to easily become obese, so I began to study this. Methods (1) Subjects The subjects of this study were 101 female patients visited Nara oriental medical hospital during 2months from April 1 to May 30 in 1999. (2) I determined finally classification of sasang constitution according to diagnosis and questions made in Nara oriental medical hospital. Results (1) 81.2% of obese patients are Taeumin, 15.8% of those are Soeumin, 3% of those are Soyangin. (2) Soeumin has significant difference that it takes over 30 minutes to have a meal. (3) Significant difference is that Soeumin goes to bed earlier in the evening than Taeumin and Soyangin. (4) From obesity of whole body point of view, Taeumin has more significant and from obesity of abdomen and leg point of view, Soeumin has more significant difference.

Since digital images and videos are rapidly increasing in the internet with the spread of mobile computers and smartphones, research on image retrieval has gained tremendous momentum. Color, shape, and texture are major features used in image retrieval. Especially, color information has been widely used in image retrieval, because it is robust in translation, rotation, and a small change of camera view. This paper proposes a new method for histogram refinement based on local color difference. Firstly, the proposed method converts a RGB color image into a HSV color image. Secondly, it reduces the size of color space from 256³ to 32. It classifies pixels in the 32-color image into three groups according to the color difference between a central pixel and its neighbors in a 3x3 local region. Finally, it makes a color difference vector(CDV) representing three refined color histograms, then image retrieval is performed by the CDV matching. The experimental results using public image database show that the proposed method has higher retrieval accuracy than other conventional ones. They also show that the proposed method can be effectively applied to search low resolution images such as thumbnail images.

The logic-based scheduling languages RSV and RCPSV may be used to represent and to solve a new general class of resource-constrained project scheduling with variants. RSV and RCPSV syntactically represent schedul7ing problems as descriptions (activity terms) being similar to concepts in a description logic. Though RSV and RCPSV have a different syntax, they are equal1y expressive. On the other hand, from a complexity point of view RCPSV permits more compact representations than RSV. We argue that the difference may be exponential.

It is very important to understand and interpret the meaning of the sigma level correctly through the Six Sigma project. Especially, the confusion over the relation between sigma level from the short-term point of view and defective proportion or DPMO from the long-term point of view may make a big gap between expected results of the Six Sigma project and real results in the field. The one-tail approximation is commonly used to calculate the sigma level both in most literatures introducing Six Sigma and actual cases of the Six Sigma project. Since the one-tail approximation undervalues the sigma level of the fields such as business and service of which the sigma level is generally low, however. there can be misleading results of the explanation of the sigma level and inappropriate project evaluation. This paper describes the relation between sigma level and defective proportion in detail and clears the difference between the one-tail and two-tail approximation.

Northeast Asian economies have achieved high levels of growth due to a stable economic environments and economic policy reforms for free trade. As Northeast Asia has been risen as big bloc in the world and in the future in case free trade agreement could be concluded, trade volume could be increased dramatically. And it is evident that disputes will be increased in Northeast Asian economic bloc. Arbitration must be popular in resolving international commercial disputes in Northeast Asian bloc in order to increase the volume of intra-trade in the bloc. Through arbitration, the parties can have full autonomy and can resolve disputes independently, impartially and without delay. But in order for the parties to make use of arbitration in the bloc, they must be fully aware of the arbitration laws of Northeast Asian nations in view of the similarity and difference of the laws. Therefore, this paper deals with arbitral award in Northeast Asian Nations' arbitration laws in view of comparative law.

Analysis has been carried out to investigate the temperature variation and the uniformity of the temperature distribution of the glass panel by infrared radiant heating. Halogen lamps are used to heat the panel and located near the top and bottom of the rectangular chamber. The thermal energy is transfered only by radiation and the radiation exchange occurs only on the solid surfaces and is considered by using the view factor. The results show that the uniformity of the temperature distribution of the panel is improved but the time for heating increases as the wall reflectivity is large. The temperature difference reaches a maximum in the early stage of the heating process and then decreases until it reaches the uniform steady-state value.

In this study, a new technique for atmospheric transmittance estimated from ALOS PRISM data is developed. It is based on satellite's observing radiances of different view angles and assumes that the cause of difference in radiances is the different view angles. The ALOS PRISM has three independent optical systems for viewing forward and backward and producing a stereoscopic image along the satellite's track. This stereo pair data can be used to estimate the transmittance according to the radiative transfer theory. This derived transmittance will be validated by the AERONET data and compared with the MODTRAN4 simulation results. Results show that the higher the land cover albedo, the better the derived transmittance compared to the AERONET data. Besides, this technique also shows the transmittance retrieval will be underestimated for the low land cover albedo.

In this paper, a novel algorithm capable of detecting generic obstacles on a flat surface is proposed. The algorithm fundamentally exploits a distortion phenomena taken place in remapping process of original stereo images to a virtual top-view. Based on the distortion phenomena, we construct stereo polar histograms of edge maps, detect peaks on them, and search for matched peaks on both histograms using a Dynamic Programming (DP). Eventually, the searched corresponding peaks lead to estimate obstacles' positions. The advantages of the proposed algorithm are that it is not largely affected by an intensity difference between a pair of stereo images and does not depend on the typical stereo matching methodologies. Furthermore, the algorithm identifies the obstacles' positions quite robustly.

The purpose of this study is to find out what type of skip button used in forced exposure advertising is the most positive to the users. The four types of skip buttons were produced for the experiment and tested by survey and eye tracker to reveal the effects of the skip buttons on perceived intrusion, advertising attention, attitude toward advertising, and memory consisting of recall and recognition. Out of 80 participants, 20 were randomly assigned to the specific type of skip button group. The results showed that there is no statistical difference in advertising attention, perceived intrusiveness and attitude toward advertising. However, the recall and recognition rate are the highest in the static text type and kinetic text, product image, and default follow statistically. This study has implications for using skip buttons as a major variable for inventory of TrueView advertising effects and suggests that the amount of information in the image is critical processed by users within very short time.
