린 화이민의 작품을 왜 대만 문화의 상징이라고 하는가. 린 화이민의 작품세계는 대만의 문화를 흡수하는 것을 목표로 삼았다. 린 화이민의 작품에 대한 분석과, 무용평론가들의 견해를 통해 린 화이민의 작품 스타일은 전기와 후기의 두 단계로 나뉜다. 전기에는 쌀, 사진, 분향이라는 세 가지 주요 요소들을 활용해 대만의 풍토에 대한 인식을 알리는 것을 목표로 작품 작업을 진행했다. 후기에는 주로 작품에 중국 특색을 띈 태극관, 무술, 서예 등을 도입해 창작에 영양을 받는 등 중국 문화를 구현하기 위해 개인적인 스타일을 만들었다. 따라서 린 화이민의 작품은 대만 문화의 결실을 농축하고 전통문화를 살리는 수단이 되기도 했다.

About 18th century in the late Chosun dynasty, various kinds of 'Min-Wha' had played a significant role and had an important meaning in the lives of the people in that period. Therefore, both in material and in technique, so many diversified 'Min-Wha' were mass produced in that time. Starting from those backgrounds, 'Hyuk-Wha', is considered as one of unique style of expression. Though, 'Hyuk-Wha', in techniques, was originated from 'Bibaekseo' classified as one of the style of expression in Oriental drawing and writing art. 'Hyuk-Wha' shows and expresses visual differentiation from rough 'Bibaekseo', in substance, written by brush made from the skin of a willow tree or the stem of a sort of reeds. 'Hyuk-Wha', in mode, has very dose relation to the process of the development of 'Min-Wha'. Judging from this point of view, 'Hyuk-Wha' has deep relationship to Taosmic character painting of 'Gilsang: an auspicious sign' or Confucian character painting of 'Hyojae: filial piety. Accordingly, 'Hyuk-Wha' has been developed to that character painting designed by another type of creative differentiations. For these reasons, 'Hyuk-Wha' which significantly shapes and contains the meanings of Chinese Character also has been esteemed to have interrelation with Pictography in application of Word mark or Brand logotype in graphic areas. 'Hyuk-Wha' which was prevalent in use of home decorations for the people existed in the past has been ceased to exist nowadays in use of home decorations by appearance of all sort of decoration articles. All these days, 'Hyuk-Wha' which was diversified as a part 'Min-Wha' and developed together with oriental drawing and writing art and character painting is to be necessarily relighted. And 'Hyuk-Wha', which is also vigorously in practical application in Western Europe is desirable to be reconsidered.

Je Baek-seok, who is well versed in poetry, calligraphy, painting, and sculpture, has established himself as the most outstanding painter and pavilion in the history of modern and contemporary Chinese art. During the Ming and Qing Dynasties, the art of the pavilion was developed greatly during the enlightenment period, with the emergence of many masters of the pavilion, including Jeonggyeong, Hwanghwangseokyeo, Oyangji, Jo Ji-gyeom, Hwang Mok-bo, and Oh Chang-seok. Je Baek-seok formed an original ritual under this social background. Je Baek-seok's tactics were formed by imitating works from the Hanwi period, and he harmonized Jin Kwon, Sopan, and Janggunin while using the penmanship of the Cheonbal Shinchambi based on the "Sasam Gongsanbi." In addition, by boldly using the Danipdo method, it is possible to use the human face as much as possible while fully exhibiting the artistry of calligraphy and adding to the atmosphere of gold stone. This paper mainly analyzed and reviewed the process of Je Baek-seok's transcription transformation and humanities practice from two aspects. First, it is planned to summarize the process of Je Baek-seok's transformation into a Jeonseo. Second, Je Baek-seok's humanities practice was analyzed. This paper will further understand Je Baek-seok's humanistic ideas and practical search by clarifying the originality of Je Baek-seok's engraving art with examples of Je Baek-seok's works, and it is believed that this will provide future scholars with learning paths and rich experiences.

Field Programmable Gate Array (FPGA) is widely used in a variety of fields because of its ability to be programmed as desired. However, when an externally implemented program is loaded on FPGA in the form of a bitstream, there is a possibility that hardware Trojans which cause malfunctions or leak information may be included. For this reason, bitstream reverse engineering is essential, and therefore related research has been conducted, such as BIL. In this paper, we analyze the BIL bitstream reverse engineering tool, which is the most representative algorithm, regarding its performance and limitations.

Perovskite solar cells have received increasing attention in recent years because of their outstanding power conversion efficiency (exceeding 22%). However, they typically contain toxic Pb, which is a limiting factor for industrialization. We focused on preparing Pb-free perovskite films of Ag-Bi-I trivalent compounds. Perovskite thin films with improved optical properties were obtained by applying an anti-solvent (toluene) washing technique during the spin coating of perovskites. In addition, the surface condition of the perovskite film was optimized using a multi-step thermal annealing treatment. Using the optimized process parameters, $AgBi_2I_7$ perovskite films with good absorption and improved planar surface topography (root mean square roughness decreased from 80 to 26 nm) were obtained. This study is expected to open up new possibilities for the development of high performance $AgBi_2I_7$ perovskite solar cells for applications in Pb-free energy conversion devices.

Recent trends for the miniaturization and weight reduction of portable electronic parts have driven uses of subminiature components. Assembly of the miniaturized components requires subminiature screws of which pitch sizes are micrometer scale. To produce such subminiature screws with high precision threads, not only a precision forming technology but also a high-precision measurement technology is required. The present study covers the development of a vision inspection system for precision screws for the automatic measurement of subminiature screws with high speed and reliability. In this study, the feeding unit that transfers the subminiature screws to the inspection unit is investigated through finite element(FE) analysis. The vibration characteristics of the feeding unit are predicted through FE analyses, from which we can determine whether the subminiature screw can be stably fed into the inspection unit or not. The effects of several design parameters on the vibration characteristics are also discussed.

In our modern society, the utilization of the advanced drone which is capable of performing variety of tasks has been gradually increasing. In this paper, we present an application, similar to the prototype "Skycall" that had been introduced in the MIT Senseable City. To assess this concept, we have implemented a prototype of drone-based pedestrian navigation depending on the Android smartphone. Our system is not only able to guide the user in a very complicated place, where buildings are compacted, but also to block unauthorized visitors from accessing the facilities. And we discuss some problems we found and suggest the direction to address them.

The purpose of this study was to validate the newly developed K-WPPSI-IV using other current IQ tests in common use in Korea such as the K-ABC and K-CTONI-2. Fifty three 2~7 year olds were tested with both the K-WPPSI-IV and K-ABC in a counterbalanced order. Simultaneous, cognitive, information processing as well as acquisition indices of K-ABC were moderately correlated with the total IQ of K-WPPSI-IV, ranging .44~.58. The results of these tests were comparable with US data: Correlations among WPPSI-IV & DAS-II subscales were .31~.67. The correlations among K-WPPSI-IV & K-CTONI-2 subscales in sixty two children ranged from .43~.49. WMI(Working memory index) as well as PSI(Processing speed index) of K-WPPSI showed low correlations with non-verbal IQ. These results indicated that nonverbal IQ does not test processing speed which in turn is very important in WMI & PSI Indices of K-WPPSI-IV. Further studies are needed to broaden the concurrent validities using K-WISC-IV or K-BSID-2. In addition, predictive as well as discriminate validity studies need to be conducted for better understanding of K-WPPSI-IV.
