In TFT-LCD, mura is a defect which degrades the display quality. The resistance difference between gate lines is the main cause of H-Block mura. Two methods could eliminate this defect. A thinner gate layer or gate fan-out pattern decrease mura level. H-Block mura has been reduced after implementing the new schemes.

A gate driver suitable for forced switch-mode power converters such as UPS and motor drive system is presented. The proposed gate driver uses regenerated snubber power and requires no separate power supply. This does not impose any additional complexity on the main switch. Experimental results show that the proposed circuit is valid.

Kunjung-mun Gate the only existing multi-level palace gate from the Chosun Dynasty, is the main fate of Kungjung-jun, the central building of Kyungbok-koong Palace. Sangryangmun(a written record of the construction of the ridge beam) of Kunjung-mun Gate was discovered in a hole under its main beam during the renovation project on September 19th, 2000. At the time of discovery, Sangryangmun was found in its original state as a rolled up scroll. On a clould-patterned, red silk cloth, 78 cm in width and 1200 cm in length, each of all 92 lines of the Kunjung-mun Sangryangmun is comprised of either 7 or 11 brush-written, ornamental "Seal" characters. With an exception of its discoloration, the material is considered well preserved. After its discovery, the National Institute of Cultural Properties stored the document in an airtight container for a permanent preservation. In accordance to the Royal Command at the time, the Kunjung-mun Sangryangmun was composed by Kim Byungi, then written by Lee Donsang on January 19th 1867. This document records the meaning and the process of the repair effort of Kunjung-mun Gate includes the wish for peace and longevity of the Chosun Kingdom and its people.

In this study is aerial photos and UAV(Unmanned Aerial Vehicle) images were used to analyzed the characteristics of depositional landform changes in the Geum river channels before and after the opening gate of Gongju weir. Based on the depositional landform classification result, the main stream and the bare land occupied most of the area in all periods, and also found that the main stream, mid-channel island, and sand bar occupied a greater degree of area increase or decrease compared to other landforms in the classification items. As a result of analyzing the characteristics of depositional landform changes before and after the opening gate of Gongju weir, it is judged that the depositional landforms have changed due to the decreased water level of the Geum river after the opening of the weir, the summer rainy season and typhoons, river stabilization after the effluence of Daecheong dam, supply and deposition of river sediments and fixation of vegetation. The results derived from this study can be used as basic data for the study of river depositional landforms and the establishment of management and conservation plans for the landforms in river channels.

Bias stress effect in pentacene organic thin-flim transistors with cross-linked PVA gate dielectric is analyzed. For negative gate bias stress, positive threshold voltage shift is observed. The injected charges from the gate electrode to the defect states of gate dielectric are regarded as the main origin of $V_T$ shift. The reduced bias stress effect using $SiO_2$ blocking layer confirms the assumed mechanism. It is also demonstrated that the inverter with $SiO_2$ blocking layer shows the negligible hysteresis owing to the reduced bias stress effect.

The development of high voltage Insulated Gate Bipolar Transistor (IGBT) have given new device advantage in the areas where they compete with conventional GTO (Gate Turnoff Thyristor) technology. The IGBT combines the advantages of a power MOSFET (Metal-Oxide Semiconductor Field-Effect Transistor) and a bipolar power transistor. The change of electrical characteristics for IGBT is mainly coming from the change of characteristics of MOSFET at the input gate and the PNP transistors at the output. The gate oxide structure gives the main influence on the changes in the electrical characteristics affected by environments such as radiation and temperature, etc.. The change of threshold voltage, which is one of the important design parameters, is brought by charge trapping at the gate oxide. In this paper, the electrical characteristics are simulated by SPICE simulation, and the parameters are found to design optimized circuits.

After the Korean war, two major attempts were made to reconstruct Gwanghwamun Gate as an important part of Korea's lost cultural heritage. In December 2006, the Korean government replaced the concrete gate with a wooden one, yet traces of the attempts made in the 1960s to transform Gwanghwamun Gate and the main road remain to this day. At the time, the Third Republic of Korea, sought to legitimize itself in the name of modernity, and went on to modernize the architecture and urban landscape of Seoul. The location and design selected for the rebuilt Gwanghwamun illustrated the symbolic relationship between historic heritage and urban development. The reconstruction of the gate began as part of the Third Republic's project to restore the Central Administration Building and culminated in the transformation of the main road in front of the gate. By reconstructing the traditional gate using concrete, the military government intended to convey the message that we could inherit our proud tradition using modern materials, and that we should actively adopt the new technologies of the modern era. This study begins with the premise that the Gwanghwamun reconstruction project of 1968 represents the application of new technological thinking to Korea's architectural style, and has two objectives. The first is to summarize the reconstruction process and method using the records and drawings from the 1968 project, which was then under the leadership of architect Kang Bong-jin. The second is to analyze the characteristics of the architectural style and structure of the reconstructed Gwanghwamun so as to reinterpret the relationship between Korean tradition and modern technology.

All the phenomena and subjects of nature and society are within correlation interconnection, and they are inseparably connected one another. The elements of this interaction can be found out through the concept of transparency in the space composition of Korean traditional architecture. This study is focusing on the access space, in other words, a gate-house that is a buffer zone playing a process role up to the main space among successive spaces. It was chosen to be the subject of the study since it strengthens convergence into the main building and with the effect connecting spaces, it could show well the spatial possibility of transparency. Besides, the subject of the study is limited to the Moonru Multi roofs that improves the functionality of spaces between gate-houses, and it is intended to progress contents by comparative analysis of two kinds such as Seo Won gate-house and temple gate-house. Korean traditional architecture places emphasis on harmony within the whole spaces. There are intimate relations between surrounding environment, external spaces and internal spaces, and it is important understand the spatial relations according to the shape appearing through interactions of parts in the whole spaces. In conclusion, the Moonru Multi roofs is analyzed with the method of extracting the concept that is contained in the frame of analysis and through ecological views through a visible and structural method. It can be understood what kinds of method for communication were used for ancestors to recognize and use spaces with the deduced concept through the analysis of the Moonru Multi roofs with different character.
