Multiculturalism may be deeply connected with the diversities of cultures and enlightenment discussed in the context that we live together with the specification of cultures derived from any spatial conditions overtly and covertly. People live on their own customs compatible with their space and the time, and they make their boundaries of races, nations, and national memories. In such a way each of them treats each other exclusively and is inclined not to recognize being of the others. Also people are apt to recognize the others unessentially and overlook the others's value and way of life. As a result they might destroy the foundation of symbiotic livings conditions on their own. On the other hand they pretend to search for the cultural diversities of the others and include them under their own universalities, resulting in conflicts. Hence it is required that we should make an efforts to prepare the fields for living together through getting over the problem of the recognition of matters and affairs before us. From the above-told critical mind this thesis seeks the multicultural relativities and more arrives at the relationalities discussed by East-Asiatic philosophers of Chuang Tzu and Ch'oe Han-gi. Especially by gazing at the idea of the interconnectedness which means activities, changeabilities and mobilities, appeared on the idea of Ch'oe Han-Gi's revolving transformation, it is stressed that the communications of the local with each other in the various aspects of, e.g. materials, regions and cultures should be achieved.

Aircraft are representative of human-machine systems. There is a delay between the human operation and the completion of the machine operation such as when the machine starts to operate and when the force is transmitted to the machine and completed. Time perception is an important component of timing tasks and is known to be affected by the anxiety associated with high arousal. This research verified the impact of weather, flight, and time conditions on the anxiety and time perception of in-service pilots in a virtual reality area. Weather conditions were divided into visual flight weather conditions and very low visibility conditions. Experiments 1 and 2 were performed with different flight and time conditions. In Experiment 1, time perception was measured by employing a button added to the control rod in the scenario of hovering and level flight with relatively little transformed in momentum and little delay. In Experiment 2, time perception was measured in the procedure of naturally taking off the helicopter by employing only the control stick in a takeoff scenario where there was a lot of transformation in momentum and a lot of delays. As a result of the experiment, it was reported that anxiety and heart rate increased in very low visibility conditions In particular, among all flight conditions in Experiments 1 and 2, it was reported that time was overestimated in the scenario of increased anxiety. This outcome can lead to overestimation of time under the impact of anxiety and failure of the timing task, which may lead to challenges in maneuvering and possibly lead to accidents.

One notable characteristic of Daesoon Jinrihoe's view of time, is its perception of time as a passive entity. This signifies that, in the context of Daesoon Jinrihoe, time is subject to influence through experience, specifically undergoing re-calibration or governance. The summary of this perspective is as follows: Firstly, Daesoon Jinrihoe's understanding of time incorporates a historical viewpoint characterized by the law of entropy, which posits that disorder increases as time progresses. Secondly, within the world established by Daesoon Jinrihoe, time experiences transformation before and after the Great Opening. Prior to this event, time follows a helical model characterized by increasing chaotic disorder, whereas in the Later World, the helical model reflects only Mutual Beneficence, symbolizing progress and development in the era. Thirdly, the Great Opening re-calibrates time, serving as the criterion for determining human life. Prior to the Great Opening, time recorded human life in a manner marked by Mutual Contention, whereas afterward, it will record human life as being characterized by Mutual Beneficence. This re-calibration of time leads precisely to directional (spatial) re-calibration. Fourthly, the Great Opening re-calibrates the order of time and space. In the Former World, space held precedence over time. However, the Great Opening changes this dynamic, with time assuming precedence over space in the Later World. In this context, the integration of time and space establishes a worldview. Fifthly, in the worldview of Daesoon Jinrihoe, time serves as a vehicle for the governance of the Supreme God. The Supreme God governs all things by controlling time, orchestrating changes spanning birth (saeng, 生), growth (jang, 長), harvest (yeom, 斂), and storage (jang, 藏), much like how problems are resolved through natural progress without requiring deliberate action. Lastly, time functions as a medium through which entities that strive to achieve unification with the Dao come to govern all things. For this reason, achieving unification with the Dao in Daesoon Jinrihoe specifically refers to the governance of time.

A transform-space index indexes objects represented as points in the transform space An advantage of a transform-space index is that optimization of join algorithms using these indexes becomes relatively simple. However, the disadvantage is that these algorithms cannot be applied to original-space indexes such as the R-tree. As a way of overcoming this disadvantages, the authors earlier proposed the transform-space view join algorithm that joins two original- space indexes in the transform space through the notion of the transform-space view. A transform-space view is a virtual transform-space index that allows us to perform join in the transform space using original-space indexes. In a transform-space view join algorithm, the order of accessing disk pages -for which various space filling curves could be used -makes a significant impact on the performance of joins. In this paper, we Propose a new space filling curve called the adaptive row major order (ARM order). The ARM order adaptively controls the order of accessing pages and significantly reduces the one-pass buffer size (the minimum buffer size required for guaranteeing one disk access per page) and the number of disk accesses for a given buffer size. Through analysis and experiments, we verify the excellence of the ARM order when used with the transform-space view join. The transform-space view join with the ARM order always outperforms existing ones in terms of both measures used: the one-pass buffer size and the number of disk accesses for a given buffer size. Compared to other conventional space filling curves used with the transform-space view join, it reduces the one-pass buffer size by up to 21.3 times and the number of disk accesses by up to $74.6\%$. In addition, compared to existing spatial join algorithms that use R-trees in the original space, it reduces the one-pass buffer size by up to 15.7 times and the number of disk accesses by up to $65.3\%$.

This study was conducted to provide basic data that can be used when establishing Net Zero policies and implementation plans for non-urban settlements by quantitatively analyzing the Net Zero contribution to green infrastructure in rural areas corresponding to non-urban settlements. The main purpose is to first, systematize green infrastructure in rural areas, secondly derive basic units for each element of green infrastructure, and thirdly quantify and present the impact on Net Zero in Korea using these. In this study, CVR(Content Validity Ration) analysis was performed to verify the adequacy of green infrastructure elements in rural areas derived through research and analysis of previous studies, is as follows. First, Hubs of Green infrastructure in rural area include village forests, wetlands, farm land, and smart farms with a CVR value of .500 or higher. And Links of Green infrastructure in rural area include streams, village green areas, and LID (rainwater recycling). Second, the basic unit for each green infrastructure element was presented by classifying it into minimum, maximum, and median values using the results of previous studies so that it could be used for spatial planning and design for Net Zero. Third, when Green infrastructure in rural areas is applied to non-urban settlements in Korea, it is analyzed that it has the effect of indirectly reducing CO₂ by at least 70.76 million tons and up to 141.16 million tons. This is 3.4 to 6.7 times the amount of CO₂ emission from the agricultural sector in 2019, and it can be seen that the contribution to Net Zero is very high. It is expected to greatly contribute to the transformation of the ecosystem. This study quantitatively presented the carbon-neutral contribution to settlements located in non-urban areas, and by deriving the carbon reduction unit for each element of green infrastructure in rural areas, it can be used in spatial planning and design for carbon-neutral at the village level. It has significance as a basic research. In particular, the basic unit of carbon reduction for each green infrastructure factors will be usable for Net Zero policy at the village level, presenting a quantitative target when establishing a plan, and checking whether or not it has been achieved. In addition, based on this, it will be possible to expand and apply Net Zero at regional and city units such as cities, counties, and districts.

Purpose: Cross-modality coregistration of positron emission tomography (PET) and magnetic resonance imaging (MR) could enhance the clinical information. In this study we propose a refined technique to improve the robustness of registration, and to implement more realistic visualization of the coregistered images. Materials and Methods: Using the sinogram of PET emission scan, we extracted the robust head boundary and used boundary-enhanced PET to coregister PET with MR. The pixels having 10% of maximum pixel value were considered as the boundary of sinogram. Boundary pixel values were exchanged with maximum value of sinogram. One hundred eighty boundary points were extracted at intervals of about 2 degree using simple threshold method from each slice of MR images. Best affined transformation between the two point sets was performed using least square fitting which should minimize the sum of Euclidean distance between the point sets. We reduced calculation time using pre-defined distance map. Finally we developed an automatic coregistration program using this boundary detection and surface matching technique. We designed a new weighted normalization technique to display the coregistered PET and MR images simultaneously. Results: Using our newly developed method, robust extraction of head boundary was possible and spatial registration was successfully performed. Mean displacement error was less than 2.0 mm. In visualization of coregistered images using weighted normalization method, structures shown in MR image could be realistically represented. Conclusion: Our refined technique could practically enhance the performance of automated three dimensional coregistration.

This paper descibes the study of application of a modified Neocognitron model with backward path for the recognition of Hangul(Korean) syllabic characters. In this original report, Fukushima demonstrated that Neocognitron can recognize hand written numerical characters of $19{\times}19$ size. This version accepts $61{\times}61$ images of handwritten Hangul syllabic characters or a part thereof with a mouse or with a scanner. It consists of an input layer and 3 pairs of Uc layers. The last Uc layer of this version, recognition layer, consists of 24 planes of $5{\times}5$ cells which tell us the identity of a grapheme receiving attention at one time and its relative position in the input layer respectively. It has been trained 10 simple vowel graphemes and 14 simple consonant graphemes and their spatial features. Some patterns which are not easily trained have been trained more extrensively. The trained nerwork which can classify indivisual graphemes with possible deformation, noise, size variance, transformation or retation wre then used to recongnize Korean syllabic characters using its selective attention mechanism for image segmentation task within a syllabic characters. On initial sample tests on input characters our model could recognize correctly up to 79%of the various test patterns of handwritten Korean syllabic charactes. The results of this study indeed show Neocognitron as a powerful model to reconginze deformed handwritten charavters with big size characters set via segmenting its input images as recognizable parts. The same approach may be applied to the recogition of chinese characters, which are much complex both in its structures and its graphemes. But processing time appears to be the bottleneck before it can be implemented. Special hardware such as neural chip appear to be an essestial prerquisite for the practical use of the model. Further work is required before enabling the model to recognize Korean syllabic characters consisting of complex vowels and complex consonants. Correct recognition of the neighboring area between two simple graphemes would become more critical for this task.

This study aims to comprehend that Gwanghalluwon for aspects of landscape change in terms of construction garden(樓園). Transformation focused on the spatial structure is divided into four periods based on literature. And reflect of landscape elements in defunct or unattributable records from tale and novel. The results were as follows. First, The beginning of Gwanghanllu pavilion(廣寒樓) was the composition of the Gwangtongnu Pavilion(廣通樓). The pavilion is located amid beautiful scenery such as the close-range view of a small stream, and distant view Jiri Mountain. Analysis of literature shows that Gwanghallu pavilion was in succession to Gwangtongnu Pavilion's landscape. Secondly, Gwanghallu(廣寒樓) pavilion represents the characteristic of the garden since 1582. Built the Samsinsan(三神山), Construct Lake and bridge that represents the galaxy for realization of utopia reflect in Taoist ideology. Thirdly, Gwanghalluwon garden was recovered when from Jeong-yu-jae-ran(丁酉再亂) to the Japanese Ruling Era. It took Gwanghalluwon garden a long while to recover from original form. According to records, Gwanghalluwon garden is still being likened to the landscape of fairyland by inheriting landscape in the previous of Jeong-yu-jae-ran(丁酉再亂). Fourth, By the modern times, Gwanghalluwon Garden has personality of tourist attractions. Until now, the area of the Gwanghalluwon garden has been expended during the processes of three times. Fifth, Aspect of landscape change of Gwanghalluwon is wide-spreading mainly Gwanghallu pavilion. But elements of external expansion in garden by introduced into the facility irrelevant to the authenticity of the garden. Sixth, Comprehension the cultural landscape of the garden are limited by deficient records. But, the main elements in the Gwanghalluwon garden are commonly appeared on imaginary environment within a tale and a novel. In addition, culture of garden at the time was depicted in tale and novel. In this sense, cultural landscape in garden was able to estimate through imaginary environment within novel.

The National Base Map construction consists of the regular correction work of dividing the whole country into two regions and carrying out the modification Plotting by aerial photographs every two years as well as the real time updating work of correcting the major change feature within two weeks by the field survey and the As-Built Drawing. In the case of the Building Layout Drawing of Korea Real estate Administration intelligence System(KRAS) used for real time updating work of the National base map, the coordinate transformation error is included in the positional error when applied to the National Base Map based on the World Geodetic Reference System as the coordinate system based on the Regional Geodetic Reference System. In addition, National Base Map is registered based on the outline(eaves line) of the building in the Digital Topographic Map, and the Cadastral and Architecture are registered based on the building center line. Therefore, the Building Object management standard is inconsistent. In order to investigate the improvement method, the network RTK survey was conducted directly on a location of the Building Layout Drawing of Korea Real estate Administration intelligence System(KRAS) and the problems were analyzed by comparing with the plane plotting position reference in National Base Map. In the case of the general structure with the difference on the Building center line and the eaves line, beside the location information was different also the difference in the ratio of the building object was different between Building center line and the eave. In conclusion, it is necessary to provide the Base data of the double layer of the Building center line and the outline of the building(eaves line) in order to utilize the Building Layout Drawing of Korea Real estate Administration intelligence System(KRAS). In addition, it is necessary to study an organic map update process that can acquire the up-to-dateness and the accuracy at the same time.
