  • Gwanghwamun Gate of Gyeongbokgung Palace was dismantled and relocated during the Japanese colonial period, destroyed during the Korean War, reconstructed with reinforced concrete in 1968, and finally erected at its present location in 2010. A pair of Haechi statues located in front of Gwanghwamun was dismantled and relocated several times, and the statues have yet to be returned precisely to their original positions. This study assesses the historical accuracy of their current placement under the Gwanghwamun Square Restructuring Project of the Seoul Metropolitan Government and the Cultural Heritage Administration based on archival photos from the early 1900s, and proposes a method to estimate the original positions of the Haechi through image analysis of contemporary photographs and recent digital camera photos. We estimated the original position of the Haechi before the Japanese colonial period by identifying the shooting location of the archival photo and reproducing contemporary photographs by calculating the angle and distance to the Haechi from the shooting location. The leftmost and rightmost Haechi were originally located about 9.6 m to the east and 7.4 m to the north and about 1.9 m to the west and 8.0 m to the north, respectively, of their current location indicators. As the first attempt to determine the original location of a building and its accessories using archival photos, this study launches a new scientific methodology for the restoration of cultural properties.

  • Recently, the miniaturization and digitalization for the inspection devices of point-of-care testing (POCT) are rapidly evolving. In the urine test, a lot of researches on index paper technology are being conducted because people can be self-diagnosed through visual color comparison using a urine test paper, Dipsick. The purpose of this study is to analyze the RGB values from the color changes on Dipstick Pad, which isused for urine test, using a smartphone camera. To this end, the primary, analytes in urine wasdiabetes-related parameters such as glucose, ketone body and pH, which is the most frequently tested elements, and we pursuited to quantify the changes in dipstick color caused from artificial urine containing different ranges of sugar, ketone body, and pH. In this experiment, changes in RGB values under bright and dark illuminances were compared, and changes in RGB value were monitored as a function of concentration of analytes under the ambient illumination of laboratory. As a result, color separation at the bright luminance region was good, but it did not appearat the low luminance region, and the changed profiles in RGB value under different illuminances was suggested to correct the problem of the color separation algorithm.

  • This study was initiated with the attention of demanding new and diverse approaches, we're talking familiar with imitations in the design process like a way to draw a image. So I studied a convergence of humanities and visual arts with the understanding and conceptual approach of the formless. The purpose of this study is to develop formless languages and to organize practical courses which are to enable deeper research and design expression on theoretical approaches and explanations of outcomes required before and after the process when we practice in connection with the formless. The method of this study is to draw detailed items from selected words through advanced researches, work and author researches and practice teaching. The results of the study I proposed the formless language that is related to the horizontality in spatial positioning system, and pulse in the separation of space and time, and entropy in structural orders of the system, and base materialism in the limitation of matter as the operating mechanism and parent item of formless. And those elements are related with shape, size, shading, color, texture, space, structure as visual elements of formative elements and those have various adjectival meanings as the subordinate concept. So I presented an education materials of basic design which is to enable understanding and expressing the formless language in the overall process of formless visual art(theoretical approach, practice course, presentation, etc.). Based on these study results, I hope that this educational materials will be used as educational contents that makes them express and understand different new beauties, and a role that reveals social identity, and a reference for research on a formless visual arts.

  • In order to survive the on-going natural resource war, Korea needs various efforts such as enhancing self-exploitation ratio, increasing the supply of new-reuse energy, strengthening cooperation with resource rich countries. Central Asian countries are geometrically far away from Korea. However, Korea should try to develop political, economic and ethnic relationship with those countries into much higher dimension to secure various natural resources. Major countries including U.S., EU. Japan and China are approaching Central Asian countries with long term perspective. Improving country-image through enlargement of ODA is the first concern of those countries. Korea should try to follow their practices. Government should try to improve Korea's image in the first place and lead economic cooperation with very detailed supportive measures to induce Korean firms' investment into the Central Asian countries. In the due process, a lot of information about those countries' political climate, social situation, ethnical composition, major religions, educational system, current state and structure of economies and industries, etc should be made available to Korean firms.

  • This study examined the effects of field complexity and type of target objects on the performance in baggage screening task. A total of 62 participants(male: 45.2%, female: 54.8%) participated and their mean age was 22.88. The simulated baggage screening task was developed for this study and after the orientation and task exercises, main experiment session was conducted. Participants performed a total of 200 tasks and 40(20%) contained target object. The complexity was set at three levels: high, middle, and low levels and the number of background items contained 20, 14. and 8 respectively. The type of target was set as gun, knife, liquid, and righter. The dependent variables were hit ratio and reaction time. The results showed that the hit ratio decreased and reaction time increased significantly as field complexity increased, and they varied depending on the type of target. The hit ratio of the knife was the highest and liquid lowest and reaction time of the knife was the fastest and liquid slowest. In addition, the interaction effect was also significant. Knife was not affected by complexity, however, small item such as lighter was most affected by complexity.

  • As business activities of firms for maximizing profits has resulted in increases in economic, social and environmental problems in regional geographies, they have stimulated some social activities through enhancing their public image and justifying their conducts. In fact, firms have been given concerned with a decrease in profits due to the promotion of their social activities required by local communities. However, firms are able to create shared value resulted in added value creation centering on shareholder as well as stakeholder by expanding increases in economic and social values. Therefore, the main purpose of this research is to draw an index which is able to evaluate the mechanism of virtuous circle resulted from creating shared value(hereafter CSV). At the same time, it has attempted to analyze some limits to and real effects of CSV by the index. The paper has analyzed the CSV of certificated coffee by using the index of sustainability in the Vietnamese coffee industry. The introduction of certificated coffee showed positive effects in the order of environmental, economic and social indicators. However, the structure of closed decision-making in Vinacafe, which is a state-firm, has not able to secure enough economic profits for CSV, leading to some limits to the formation of virtuous circles in the Vietnamese certificated coffee industry.

  • Following the uprise of the Korean Wave, Korean big entertainment corporations, such as SM or YG, are selling cultural products through their subsidiaries. These cultural products or 'cultural goods' are using artists' images of the entertainments for various products including stationary, consumer electronics, cosmetics, snacks, etc, to produce significant profits. We focused on the level of marketing strategy that affects the intention of purchase of those cultural goods. Specifically, we classified three levels including product-level(quality and design), brand-level(price and brand name), and corporate-level(merchandising and sales methods) and investigated if consumer nationality has any effects on the relationship. Based on the survey results performed by 220 Korean and Chinese college students, we found that Chinese consumers generally have higher intention to purchase on Korean cultural goods. Especially, Chinese consumers showed that their purchase intention is affected by price and brand name strategies, thus we found that they are more sensitive to brand-level marketing strategies.

  • Ga-doped ZnO thin films by RF magnetron sputtering process were synthesized according to the deposition conditions of O2 and Ar atmosphere gases, and rapid heat treatment (RTA) was performed at 600℃ in an N2 atmosphere. The thickness of the deposited ZnO : Ga thin film was measured, the crystal phase was investigated by XRD pattern analysis, and the microstructure of the thin film was observed by FE-SEM and AFM images. The intensity of the (002) plane of the X-ray diffraction pattern showed a significant difference depending on the deposition conditions of the thin films formed by O2 and Ar atmosphere gas types. In the case of a single thin f ilm doped with Ga under O2 conditions, a strong diffraction peak was observed. Under O2 and Ar conditions, in the case of a multilayer thin film with Ga doping, only a peak on the (002) plane with a somewhat weak intensity was shown. In the FE-SEM image, it was observed that the grain size of the surface of the thin film slightly increased as the thickness increased. In the case of a multilayer thin film with Ga doping under O2 and Ar atmosphere conditions, the specific resistance was 6.4 × 10-4 Ω·cm. In the case of a single thin film with Ga doping under O2 atmosphere conditions, the resistance of the thin film decreased. The resistance decreased as the thickness of the Ga-doped ZnO thin film increased to 2 ㎛, showing relatively a low specific resistance of 1.0 × 10-3 Ω·cm.

  • The purpose of this study is to analyze the differences in Mulan character makeup and to determine whether the makeup of the period reflects the traditional culture through the analysis of Mulan's movies produced in the background of the Mulan Si story in the period of China's North and South Dynasties, the Sui Dynasty, and the Tang Dynasty. The research method is to analyze makeup images. Mulan's usual appearance at home, the appearance in the military, and the appearance of Mulan after wearing makeup were compared to the actual makeup of North and South Dynasties, the Sui Dynasty, and the Tang Dynasty. There are three works refer to the period makeup: the movie (2020), (2020), and the drama (1998). Two Mulan films, (2020) and the movie (2020) use makeup from the North and South Dynasties such as Eo Hwang-jang, Myeonyeop, and Sa Hong to create the character Mulan. (1964) is a work based on the makeup culture of the Tang Dynasty of the Sui Dynasty. Through this paper, hope to look forward to the development of Mulan-related movie works in the future, and at the same time, it is considered that the make-up production according to the periods will be helpful in the creation of movie when producing movie in the background of the North and South Dynasties, the Sui Dynasty, and the Tang Dynasty.

  • In this study, we prepared a pigmented skin model, KeraSkin-MTM for the in vitro evaluation of whitening agents. For the purpose of complementing the existing mono-layer cell culture testing method, KeraSkin-MTM was produced through the co-culture of human skin-derived keratinocytes and melanocytes. The efficacy of four well-known whitening agents (arbutin, ascorbic acid, kojic acid, niacinamide) was evaluated in KeraSkin-MTM in order to assess its usefulness in assessing whitening efficacy. As a result, it was possible to observe additional details such as the distribution of melanin granules and melanin capping in each skin layer through KeraSkin-MTM, which was previously difficult to assess in the traditional 2D cell culture system. In addition, quantification through image analysis of KeraSkin-MTM allowed for a statistical analysis of the whitening effects. These results suggest that the KeraSkin-MTM can be used as a new evaluation method of evaluating whitening efficacy, as well as complement the traditional total melanin content and tyrosinase inhibition assays.
