We explored a new way of designing dynamic logic gates with low temperature polysilicon thin film transistors to increase the speed. The proposed architecture of logic gates utilizes the structural advantage of smaller junction capacitance of thin film transistors. This method effectively blocks leakage of current through the thin film transistors. Furthermore, the number of transistors used in logic gates is reduced thereby reducing power consumption and chip area. Through HSPICE .simulation, it is confirmed that the circuit speed is also improved in all logic gates designed.

In this paper, quantum mechanical simulations of the double-gate ultra-thin body (DG-UTB) MOSFETs are performed according to the International Technology Roadmap of Semiconductors (ITRS) specifications planned for 2020, to devise the way for on-current ($I_{on}$) improvement. We have employed non-equilibrium Green's function (NEGF) approach and solved the self-consistent equations based on the parabolic effective mass theory [1]. Our study shows that the [100]/<001> Ge and GaSb channel devices have higher $I_{on}$ than Si channel devices under the body thickness ($T_{bd}$) <5nm condition.

The purpose of this study is to suggest a scheme to provide children safer and more comfortable walking circumstances by survey current walking circumstances of schoolzone ways. A scheme suggested in this study was based on the analysis of survey to elementary school in 3 Newtowns(Dongtan, Dongbaek and Gumdan City) and actually surveyed data on school zone, the scheme can be summed up as follows; First, to avoid pedestrian roads being interrupted and to expend waiting space near schoolzone ways, several measures are needed including fixing roads and building additional gateway. Second, pedestrian crossings in front of school gate should be located at least 30m away from the left side of the gate. Third, to secure pedestrians' safety in school zone ways should be planed and established more security concepts und facilities.

Objective : There was no attempt to understand Moving Energy between two kidneys(腎間動氣) and Kidney on Left & Life Gate on Right(左腎右命門) by integration progress. So I have faced to study based on two parts with concerning as clues. One is 'Life Right (左 右)' and the other is 'Between(間)'. Methods : Revealing the source of the origin, Nanjingbenyi(難經本義) is given on the basis. Take a close look at publications related to Nanjing(難經) which is about Kidney on Left & Life Gate on Right and Moving Energy between two kidneys. Take a close look at Kidney, the Life Gate and Moving Energy between two kidneys. Look see the three-dimensional uplift movement of Gi(氣). Results : In Neijing(內經) and Nanjing, the basic point of view for Kidney is the same. That is explained in line with attributes of convergence(收斂). 'Life Gate(命門)' is a term to express the divergence feature(發散機能) of kidney. Moving Energy between two kidneys is used to mean the mainspring of human body activity. The Gi in human body loses altitude turning left(左旋而下降) and gains height turning right(右旋而上升). Conclusion : Watching on functional aspect, there are two names for kidney. One is 'Kidney(腎)' which collects the losing altitude turning left and the other is 'Life Gate' which rises turning right. Moreover, the fundamental power that effectuate the uplift movement is Moving Energy between two kidneys. This kind model is a way that can be understood syntagmatically the Kidney on Left & Life Gate on Right and the Moving Energy between two kidneys without any gainsaying the original of Nanjing.

본 조사는 월령이 망(보름)인 2016년 4월 22~23일과 5월 25~26일에 낙동강 하굿둑 갑문과 어도 등 총 4개 지점에서 실뱀장어 이동 가능성에 대한 현장 조사를 실시하였다. 실뱀장어는 총 23개체가 채집되었으며, 지점별로 보면 동편 하굿둑에서 22개체, 서편 하굿둑에서 1개체가 채집되었다. 소상지원 시설물 형태 변화, 즉 갑문의 패들 및 어도의 수문 개방 여부, 인조잔디 및 솔의 설치에 따른 실뱀장어의 채집 개체수의 변화를 보면, 동편 하굿둑 갑문의 경우 5개체에서 15개체로 3배 상승하였고, 2번 어도의 경우 0개체에서 2개체로 상승하였다. 본 조사는 2회 조사 결과로 표본수가 작아 모집단에 대한 대표성은 결여되어 있으나, 낙동강 하굿둑 어도와 갑문 모두에서의 실뱀장어를 채집하여 실뱀장어의 하굿둑 어도와 갑문 이용 가능성을 확인하였다. 뿐만 아니라 하굿둑 어도 및 갑문의 소상지원 시설물 형태변화에 따른 실뱀장어 채집 개체수가 현저한 차이를 보여주고 있어, 향후 실뱀장어 회유시기에는 하굿둑 어도 및 갑문을 능동적으로 운영해야 할 것으로 사료된다.

The tidal current power is the power plant by installing the turbine or rotor where the tidal speed is fast. This system converting the horizontal movement to rotating energy. Tidal power turbine is needed for the dam to utilize the pressure difference. However, tidal current power using the only flow. The tidal current power was evaluated as the impact on the marine environment surrounding was less and the development of eco-friendly way. In this article, we calculated the effect of tidal current turbine on the tidal power generating by mean of CFD. With these calculated results, we checked the possibility of tidal current power using tidal power plant the discharge gate.

The purpose of this study is to investigate the change of Hidden gates form with the times. Fortresses position is constructed on the Korea mountain ranges. Hidden gate, one of facilities to construct fortress among various factors, represents as route of supplies way, ask for rescue, or counterattack plan to come in. The shape of hidden gate changes depend on land form, function, and time period. Previous research partially based on archeology or history. This research analyze Namhan mountain Namhansansung, one of the highest hidden gates count in Korea, distributive by main fortress, Bong-am fortress, Hanbong fortress. Nahhan Mountain fortress repeatedly affected by King Injo in Joseon Dynasty. As a result, Nahhan Mountain fortress consist of hidden gates alternation depend on the time of establishment or extension which makes different shape or size.

The traditional mixture of experts (ME) modeled the gate network using a certain parametric function. However, if the assumed parametric function does not properly reflect the true nature, the prediction strength of ME would become weak. For example, the parametric ME often uses logistic or multinomial logistic models for the network model. However, this could be very misleading if the true nature of the data is quite different from those models. Although, in this case, we may develop more flexible parametric models by extending the model at hand, we will never be free from such misspecification problems. In order to alleviate such weakness of the parametric ME, we propose to use the semi-parametric mixture of experts (SME) in which the gate network is estimated in a non-parametrical way. Based on this, we compared the performance of the SME with those of ME and neural networks via several simulation experiments and real data examples.

This study aims to analyze the influence of parents' nurturing attitude on the children's self-esteem by comparing and analyzing the self-esteem of target children of gifted and talented education (GATE) and nongifted children with parents' nurturing attitude. The targets of this study are total 656 children in total. This study can be summarized as below. First, the self-esteem of target children of GATE turned out to be higher than that of nongifted children in overall, social, domestic and school life. Second, the nurturing attitude of parents felt by the target children of GATE is, from both father and mother, more affectionate, autonomous, achievement-oriented and rational. The parents of target children of GATE are more free in communication and fathers are aggressively in education; compared to parents of nongifted children, they put more importance on the course of achievement and help their children's achievement with actual way compared to the parents of nongifted children. Third, the relevance between self-esteem and parents' nurturing attitude is different in sub-areas. The self-esteem at home is the most relevant with parents' nurturing attitude, and the self-esteem at school is more affected by other factors than by the parents' nurturing attitude.
