  • The GOCI atmospheric correction overland surfaces is essential for the time-series analysis of terrestrial environments with the very high temporal resolution. We develop an operational GOCI atmospheric correction method over land surfaces, which is rather different from the one developed for ocean surface. The GOCI atmospheric correction method basically reduces gases absorption and Rayleigh and aerosol scatterings and to derive surface reflectance from at-sensor radiance. We use the 6S radiative transfer model that requires several input parameters to calculate surface reflectance. In the sensitivity analysis, aerosol optical thickness was the most influential element among other input parameters including atmospheric model, terrain elevation, and aerosol type. To account for the highly variable nature of aerosol within the GOCI target area in northeast Asia, we generate the spatio-temporal aerosol maps using AERONET data for the aerosol correction. For a fast processing, the GOCI atmospheric correction method uses the pre-calculated look up table that directly converts at-sensor radiance to surface reflectance. The atmospheric correction method was validated by comparing with in-situ spectral measurements and MODIS reflectance products. The GOCI surface reflectance showed very similar magnitude and temporal patterns with the in-situ measurements and the MODIS reflectance. The GOCI surface reflectance was slightly higher than the in-situ measurement and MODIS reflectance by 0.01 to 0.06, which might be due to the different viewing angles. Anisotropic effect in the GOCI hourly reflectance needs to be further normalized during the following cloud-free compositing.

  • Perceived meaning of color uniquely forms and is being highlighted as an element of creative design in the modern design industry as well as traditional culture. It is necessary to compare the perceived meanings of color and clothing color of Korea and Japan in order to find out the model of Korea's original color. The purpose of this study Is to draw the results of examining the perceived meanings of color revealed in the culture, arts and clothing color of the both countries and comparing them depending on contemporary times. The scope of study is limited from the ancient times to modern times (about BC.IC-early20C). In the methodologies, the literature and the empirical study focus on both counturies' literature, including art history, ethnology, and the history of clothing; and their paintings and relics, which are all related to clothes. The perceived meaning of color of Korea was prominent with the beauty of nature and gorgeousness throughout the history. The colors were mostly white colors, light colors, and single colors such as obangsaek, which are high pure degree colors by which color is changed depending on darkness and lightness, while that of Japan featured clothing colors combining various colors and middle colors.

  • Cultural products reflect a living culture and evolve despite being based on traditional forms only. It is known as traditional cultural expression that portray certain culture groups, materials, spiritual and creativity inspired from their living environment that characterize a society. The old Malay community had a close relationship with their surrounding and environment. Sensitivity towards the nature and surrounding environment moved them into creative people. In designing the local traditional textile, role of the motifs, design and product design play an important element in Malay cultural values. This reflects the symbols and philosophy of the arts and culture and thus becomes the identity of the Malay community, which in general practice their culture and tradition based on Islamic culture and religion. Kelantan and Terengganu are the pioneer states for most producers of Malay traditional textiles. In these states the Pelangi cloths, is one of the unique textiles use and inherited by the Malay communities. Base on history, the Malay rulers and Malay nobility used Pelangi cloth as complementing clothing and ornament in attending various ceremonies and customs in their daily life. In this paper will discuss the specific picture of Pelangi motifs, design and its usage in Malay society in Malay Peninsula through its identification aspect of representations. It shows that this textile represent certain insights of Malay customs and identity.

  • This paper focuses on the rewards, one of the elements(goal, competition, and reward) of gamification, and investigate the actual cases of its application to real variety shows. In this paper, I analyzed <2 Days and 1 Night> which offers trivial(general) rewards, and which offers special(unusual) rewards, and which offers "vernacular" rewards. Unlike specific rewards, abstract ones were estimated to bring about weak gamification effects. In Youn's Kitchen, however, the cast members felt that they received individual and subjective rewards despite its invisible rewards. And the show even reinforced the complete nature of its narrative structure. These results shows that real variety shows can have new and diverse reward structure.

  • In orthopedic surgery and in particular in total hip arthroplasty, the implant fixation is carried out using a surgical cement called polymethylmethacrylat (PMMA). This cement has to insure a good adhesion between implant and bone and a good load distribution to the bone. By its fragile nature, the cement can easily break when it is subjected to a high stress gradient by presenting a craze zone in the vicinity of inclusion. The focus of this study is to analyze the effect of inclusion in some zone of cement in which the loading condition can lead to the crack opening leading to their propagation and consequently the aseptic loosening of the THR. In this study, the fracture behavior of the bone cement including a strange body (bone remain) from which the onset of a crack is supposed. The effect of loading condition, the geometry, the presence of both crack and inclusion on the stress distribution and the fracture behavior of the cement. Results show that the highest stresses are located around the sharp tip of bony inclusion. Most critical cracks are located in the middle of the cement mantle when they are subjected to one leg standing state loading during walking.

  • Characteristic parameter values of seismic isolators deviate from their nominal design values due to uncertainties and/or errors in their material properties and element dimensions, etc. Deviations may increase over service life due to environmental effects and service conditions. For accurate evaluation of the seismic safety level, all such effects, which would result in deviations in the structural response, need to be taken into account. In this study, the sensitivity of the probability of failure of the structures equipped with nonlinear base isolation systems to the uncertainties in various isolation system characteristic parameters is investigated in terms of various isolation system and superstructure response parameters in the context of a realistic three-dimensional base-isolated building model via Monte Carlo Simulations. The inherent record-to-record variability nature of the earthquake ground motions is also taken into account by carrying out analyses for a large number of ground motion records which are classified as those with and without forward-directivity effects. Two levels of nominal isolation periods each with three different levels of uncertainty are considered. Comparative plots of cumulative distribution functions and related statistical evaluation presented here portray the potential extent of the deviation of the structural response parameters resulting from the uncertainties and the uncertainty levels considered, which is expected to be useful for practicing engineers in evaluating isolator test results for their projects.

  • The special characters of traditional architecture has been formed suitably correspond with the purpose of usage and function, which was influenced with various environmental factors such as natural, social, physical, cultural and thoughtful. There was some differences in building placement and space composition according to the regional character such as climate, customs, and a gap of convention (long-established custom) and one's social position system and custom character of family. However, the essential characteristic of traditional architecture are nicely contain the era's architectural character. But these characters are developed or extinct according to the environmental factors. This paper is looking for the elements that formed social cultural element and background architect's thought. And, with the historical background, there are looking for Occupation. A traditional architecture had been formed correspond with the purpose of usage and function, which was influenced with physical nature environment elements such as regional character, climate, customs and social cultural environment elements such as government, economy, society, culture and thoughtful elements.

  • This study investigated users' perceptions and attitudes toward Korean traditional elements in contemporary spaces. We collected and analyzed the article contents of two design magazines, from their issues of January 2000 through December 2009, for a total of 87 cases. The results were as follows. First, the important motives for applying traditional elements to current living spaces were individual tastes, preference for a secluded life, and the users' childhood memories. Second, the most frequently used traditional element was traditional structure. Others were traditional spatial compositions and the use of natural materials. The two main purposes for renovating a space or constructing a building were to preserve traditional ambience or to add convenience and practical use to it. Third, the most frequently mentioned advantages of traditional elements were their environment-friendly characteristics, such as connecting to nature and using natural materials. Fourth, the users preferred, in order, Ma-dang, natural environments, doors/windows of various types and multiple functions, Toet-maru, Dae-cheong, and Nu-maru.

  • As urbanization becomes widely spread, environmental benefits of natural landscapes have been highly appreciated. The social demands to conserve such landscapes are becoming stronger in modem society. In order to effectively manage natural landscapes, one should know what natural landscapes are. The characteristics of natural landscapes revealed by foreign research include wilderness, absence of human intrusion, and presence of diverse natural element (plants, trees, waters). The purpose of this paper is to investigate the characteristics of diverse natural landscapes with different levels of naturalness. The methods adopted here consist of three phases. First, 368 landscapes were photographed to include different levels of naturalness. Second, two professional landscape groups assessed the degree of naturalness of the collected landscapes, in which the characteristics of five degrees of naturalness were examined. Lastly, undergraduate students, as laypersons, assessed the 33 landscapes that were selected as representative of the five degrees of naturalness. The results show that there is no difference between professionals and laypersons on the assessment of naturalness of landscape. The characteristics of natural landscape that participants perceive include no human intrusion, preservation of original state, traditional quality such as Korean-style architecture, dominance of natural elements, and minimum facilities that harmonize with natural surroundings, Many characteristics are similar to the results of foreign research, However, the results reveal that Koreans do not perceive man-made nature as natural, while they perceive traditional elements as natural. Based on the results, some suggestions for landscape management are presented in the conclusion section.
