Modern architecture tends to split the everyday life and the space of human. Position of architecture should be on the relationship between nature and human need. It will be study on the everyday life of architecture from architecture and everyday life of human relationships. Based on this study, it makes clear the visual aspects of architectural experience to acquire spatial tones for analyzing architectural Everyday-ness. In this case, Portugal's modern architectural space was impressing, because of the construction of local color and architectural vocabulary of the Everyday-ness. Therefore, the Everyday-ness of Architecture by relationship analysis reveals the space of these spatial tones. Spatial characteristics of the Everyday-ness of architecture be analyzed of simplicity, purity, locality, reminiscent, continuity, and transition, etc. Expression elements of spatial tones can be derived into five classes such as light, color, material, pattern (texture), and depth. In conclusion, spatial characteristics of the Everyday-ness and expression elements of spatial tones consist of configuration matrixes to analyze the spatial tones of the contemporary architecture in Portugal. As a result of this study, the expression characteristics of spatial tones of contemporary architecture in Portugal are background-ness, one-ness, and inherence. I hope this study will be applied to the basic data of the architectural Everyday-ness.

Purpose: Recently, non-exposure simple suturing endoscopic full-thickness resection (NESS-EFTR) was developed to prevent tumor exposure to the peritoneal cavity. This study aimed to evaluate the feasibility of NESS-EFTR with sentinel basin dissection for early gastric cancer (EGC). Materials and Methods: This was the prospective SENORITA 3 pilot. From July 2017 to January 2018, 20 patients with EGC smaller than 3 cm without an absolute indication for endoscopic submucosal dissection were enrolled. The sentinel basin was detected using Tc^99m-phytate and indocyanine green, and the NESS-EFTR procedure was performed when all sentinel basin nodes were tumor-free on frozen pathologic examination. We evaluated the complete resection and intraoperative perforation rates as well as the incidence of postoperative complications. Results: Among the 20 enrolled patients, one dropped out due to large tumor size, while another underwent conventional laparoscopic gastrectomy due to metastatic sentinel lymph nodes. All NESS-EFTR procedures were performed in 17 of the 18 other patients (94.4%) without conversion, and the complete resection rate was 83.3% (15/18). The intraoperative perforation rate was 27.8% (5/18), and endoscopic clipping or laparoscopic suturing or stapling was performed at the perforation site. There was one case of postoperative complications treated with endoscopic clipping; the others were discharged without any event. Conclusions: NESS-EFTR with sentinel basin dissection is a technically challenging procedure that obtains safe margins, prevents intraoperative perforation, and may be a treatment option for EGC after additional experience.

We modified the optical system of 500 mm wide-field telescope of which point spread function showed an irregularity. The telescope has been operated for Near Earth Space Survey (NESS) located at Siding Spring Observatory (SSO) in Australia, and the optical system was brought back to Korea in January 2008. After performing a numerical simulation with the tested value of surface figure error of the primary mirror using optical design program, we found that the surface figure error of the mirror should be fabricated less than root mean square (RMS) $\lambda$/10 in order to obtain a stellar full width at half maximum (FWHM) below $28\;{\mu}m$. However, we started to figure the mirror for the target value of RMS $\lambda$/20, because system surface figure error would be increased by the error induced by the optical axis adjustment, mirror cell installation, and others. The radius of curvature of the primary mirror was 1,946 mm after the correction. Its measured surface figure error was less than RMS $\lambda$/20 on the table of polishing machine, and RMS $\lambda$/15 after installation in the primary mirror cell. A test observation performed at Daeduk Observatory at Korea Astronomy and Space Science Institute by utilizing the exiting mount, and resulted in $39.8\;{\mu}m$ of stellar FWHM. It was larger than the value from numerical simulation, and showed wing-shaped stellar image. It turned out that the measured-curvature of the secondary mirror, 1,820 mm, was not the same as the designed one, 1,795.977 mm. We fabricated the secondary mirror to the designed value, and finally obtained a stellar FWHM of $27\;{\mu}m$ after re-installation of the optical system into SSO NESS Observatory in Australia.

This study is to investigate the fitness of tight skirt in moving lower limb. The fit- ness was tested by measuring the step length, stride length, maximum stair step height. One humdred and twenty female subjects participated in the experiment. It was shown that the tight skirt caused the most reduction in the maximum stair step height among the five lengths measured. It was also shown that the long tight skirt limited the maximum stair step height more than the mini tight skirt.

The purpose of this study is to delve into the identity of the New-Hanbok style in modern fashion, and to survey its formative characteristics and internal values from the perspective of vernacular design. Arguments can be summed up as follows. The study historically examines the changes in Hanbok and concludes that the social and cultural backgrounds and factors that caused the advent of the New Hanbok are (1) the change and expansion of the basic social, cultural, and popular perception toward the Korean image, (2) the rapid spread of a subculture centering on the younger generation, and (3) the voluntary and systematic activities of nonprofit clubs, communities and private organizations. This is the cycle of the spread of Hanbok, which shows the subcultural selection and development process of upward propagation. Furthermore, the public, in addition to holding fast to an independent attitude regarding their choices, also show that they tolerate diversity. As a perspective of analyzing the New Hanbok style, the study suggests the characteristics of the vernacular design perspective as (1) a spontaneous indigenous nature (2) living everydayness (3) and the subcultural-ness of the era. From such a perspective, the study examines the formative characteristics of the basic costume configuration of the New Hanbok style including jeogori, traditional Korean skirts, Cheollik one-pieces, and Trompe l'oeil one-pieces, and draws out the meanings contained in the New Hanbok style, which are (1) spontaneous indigenous nature and directivity toward tradition, (2) living everydayness and modernity, and (3) open subcultural-ness.

This research was to examine the correlation between body composition and life style including nutrients intake and physical activities of male and female athletes and nonathletes who are attending college. The percent of body fat with a skinfold caliper was measured higher in female than male. The body fat of the female students in the nonathletic group was the highest and male students in the nonathletic group showed the lowest in body fat. On the correlation between skinfold thickness and body composition the skinfold thick-ness showed negative correlation with the body density. However it showed positive correla-tion with the percent of body fat. According to this result it can be defined that skinfold thickness is in proportion to the body fat. dietary intakes of male and female athletes exceeded the need for their excessive physical activity. Concerning the correlation between calorie intake and body fat was high. From this we conclude that the more one consumes calorie intake the higher one's body fat content will be. On the correlation of physical activity and body composition the lean body mass showed high positive correlation with physical activity.

This paper is to take note of national, social and economic movement, social & economic publicness of religion surrounding Yeonggwang, Joennam around 1910s. At first I would like to look at this period because regional society was in the middle of change of large transition before and after Japan's forced occupation of Korea in 1910s and March 1st Independence Movement in 1919. In particular we focus on spatially Yeonggwang in Joennam because this area is not only called as advent area of Buddhism earlier but also is unique regional culture and ideological topology where Donghak, Protestantism, Catholic, Institute of Won Buddhism and etc. Through casting light upon the above, it is expected to offer one clue for the question of internalizing value to be sought for in the national and social and economic movement by Korean religion around 1910 and public goods in the strategy and tactics to be selected and further publicness and practice lying in their awareness and behavior. In particular it is thought to have advanced the accumulation of case study of Yeonggwang in Joennam with representative 'place-ness' related to this. Along with this it is considered that our challenge is to restore and casting light again on common foundation of existence shape and publicness of various religions in the middle of national and social movement and economic movement in Yeonggwang of Joennam area. In other words, we expect that religions will continue individual efforts and common practices to urge social justice for historic and public value based on common good encompassing historic value, in other words, individual responsibility and social justice among social and economic conditions originated from Japanese colonial era.

An intermediate images generation method using multi-resolution based hierarchical block matching disparity map is proposed. This method is composed of a disparity estimation, an occlusion detection and intermediate image synthesis. For the disparity estimation, which is one of the important processes in intermediate image synthesis, we use the multi-resolution based hierarchical block matching algorithm to overcome the imperfect ness of block matching algorithm. The proposed method makes disparity maps more accurate and dense by multi-resolution based hierarchical block matching, and the estimated disparity maps are used to generate intermediate images of stereo images. Generated intermediate images show 0.1∼1.4 ㏈ higher PSNR than the images obtained by block matching algorithm.

In this paper a new concept, named the Extended Operational Space Formulation, has been proposed for the effective analysis and real-time control of the robot manipulators with kinematic redundancy. The extended operational space consists of operational space and optimal null space. The operational space is used to describe robot end-effector motion; whereas the optimal null space, defined as the target space of the self motion manifold, is used to express the self motion for the secondary tasks. Based upon the proposed formulation, the kinematics, statics, and dynamics of redundant robots have been analyzed, and an efficient control algorithm has been proposed. Using this algorithm, one can optimize a performance measure while tracking a desired end-effector trajectory with a better computational efficiency than the conventional methods. The effective ness of the proposed method has been demonstrated with simulations.

Image compression plays an important role in encoding and improving various forms of images in the digital era. Recent researches have focused on the principle of deep learning as one of the most exciting machine learning methods to show that it is good scheme to analyze, classify and compress images. Various neural networks are able to adapt for image compressions, such as deep neural networks, artificial neural networks, recurrent neural networks and convolution neural networks. In this review paper, we discussed how to apply the rule of deep learning to obtain better image compression with high accuracy, low loss-ness and high visibility of the image. For those results in performance, deep learning methods are required on justified manner with distinct analysis.
