본 논문에서는 binary offset carrier (BOC) 신호 추적을 위해 주변 첨두는 완벽히 제거하면서, 기존의 BOC 상관함수들보다 좁은 폭의 주 첨두를 갖는 새로운 BOC 상관함수를 제안한다. 구체적으로는 BOC 신호를 구성하는 부반송파 펄스를 펄스 구간이 더 좁은 두 개의 펄스의 합으로 해석하고, 그에 따른 부분상관함수들을 생성한다. 이후 부분상관함수들을 재조합함으로써 주변 첨두를 제거하면서도 기존 BOC 상관함수보다 상관함수의 폭이 좁은 새로운 상관함수를 생성한다. 모의실험을 통해 제안한 상관함수를 이용한 경우, 기존의 상관함수들을 이용한 경우들에 비해 더욱 향상된 신호 추적 성능을 가지는 것을 보인다.

So far, geomorphologic dispersion due to the heterogeneity characteristics of flow paths in a basin has been demonstrated as a major factor affecting to the hydrologic response function of a catchment. This effect has considered by many previous studies taking into account flow path length factors, especially in the application of width function. Based upon the analysis of topographic index, another important geomorphologic factor extracted from DEM data, this work presents a new factor named saturation to evaluate its effects to the formation of the well-known instantaneous unit hydrograph (IUH) in Nash model and drainage structure in a river basin. First, the geomorphologic parameters corresponding to different saturation conditions are computed from DEM data with the support of GIS software. Then, in the combination of hydrologic and geomorphologic data, effective rainfall in each saturation degree and the Nash parameters are calculated using excel. Finally, the verification process with direct runoff data is conducted using Fortran programming. This process is applied to five sub-watersheds in Bocheong catchment ($485.21km^2$) in Korea where the necessary data are available and believable. The results from this approach will improve researchers and students'understandings about the relationship between rainfall and runoff and its relation with drainage structure within a catchment.

University is very big scale among urban facilities as for single facilities and there is characteristic that accompany various university support functions in contiguity area. Width that have diverse spatial configuration generally our country university campus around was formed, this does function that connect university and ambit. Specially, formation enables change of spatial configuration that existent width system has if is new around university campus. Also, can form more animate and lively width spatial configuration by forming more various and complex width spatial configuration in width had formed in existing. It is that search special quality of university surrounding width spatial configuration analyzing existing width spatial configuration of Kangwon National University back gate by formation if this study is new in city and forecasts the change, and used space syntax by spatial configuration analysis method.

When adding shoulder pads to clothing, the shoulder pads brings down the quality of armpit area and the width of shoulder area, 1.5㎝ thick non-woven shoulder pads are good for sensory evaluation but do not function as well. Therefore this study has done to come up with a solution to satisfy both sensory evaluation and functionality. The study did was by using laboratory blouses with three different types of shoulder pads, which were two different armpit depths (1.0㎝, 2.0㎝), 3 types of armpit widths (0.5㎝, 1.0㎝, 1.5㎝). The Result are as followed : 1. The sensory evaluation was affected the most by the armpit depths and shoulder lengths. 2. There were two results for the best sensory evaluation, they were the one with a pad of armpit depth of 1.0㎝, armpit width of 1.5㎝, and shoulder width of 1.5㎝. 3. The functionality was affected in an order of movement, armpit width, and shoulder width. 4. The two results for the best functionality were the one with shoulder pads of armpit depth of 1.0㎝, armpit width of 1.5㎝, and shoulder width of 1.5㎝, and the one with armpit depth of 1.0㎝, armpit width 1.5㎝, and shoulder width of 1.5㎝. 5. In conclusion, 1.2㎝ nonwoven shoulder pads on a blouse with a pattern of armpit depth of 1.0㎝, armpit width of 1.5㎝, and shoulder width of 0.5㎝ will satisfy both sensory evaluation and functionality at the same time.

A novel pulse-width-modulated (PWM) function is introduced for precise position measurement in an enclosed signal field. An amplitude modulation was used to light the LEDs for the conventional study. However, the transform properties from the driving signal to the lighting intensities of the LEDs are non-linear, and accurate control of the lighting power was necessary. Therefore, a lighting function independent of these properties is desired. Well-known PWM functions are used to construct the enclosed signal field by simulation, and the precision of the phase detecting system is analyzed. A novel "axial symmetry PWM" function is found to be effective for orthogonal pahse detection.

본 연구에서는 폭함수(width function)에 기초한 단위도법(WFIUH)을 이용하는 수문곡선 산정방법에 대하여 소개하고 실제 유역(청미천)에 적용하여 그 적용성을 검토하였다. 기존 집중형 모형과 비교하여 WFIUH는 매개변수를 물리적으로 결정할 수 있는 특징이 있으며 준분포형 모형으로 유역특성 및 강우의 시공간적 변동성을 수문곡선 산정에 반영할 수 있는 장점이 있다. 공간적으로 균등한 강우를 가정하여 청미천 유역에 적용한 결과 관측치와 잘 일치하는 것을 알 수 있었으며 범용 모형인 HEC-1와 비교하여 유사한 결과를 보이는 것으로 나타났다. 또한 이동강우에 대한 간단한 검토사례를 통해 WFIUH를 이용하여 강우이동이 수문곡선의 모양과 첨두유량에 미치는 영향을 평가할 수 있는 것을 보였다.

Purpose. This study was to investigate the relationship between hand function and characteristics of hand. Methods. Participants were 56 occupational therapy students who studied in M colleges in Gyengsangnam-do, april 20, 2015 from 1 May, and hand circumference and length (vertical, w), the width was measured. A hand grip on the measurement subject was measured by the Grip dynamometer and Pinch gauge. Results. The results was hand length, width, circumference long, broad, thick, and hand strength was a greater correlation emerged. Grip strength was showed a significant correlation to the size and grip strength was also correlated. Conclusion. This study was correlation of length of the hand, a length wide and strength of the finger circumference.

In this paper, simple but very effective techniques to suppress subthreshold hump effect for high-voltage (HV) complementary metal-oxide-semiconductor (CMOS) technology are presented. Two methods are proposed to suppress subthreshold hump effect using a simple layout modification approach. First, the uniform gate oxide method is based on the concept of an H-shaped gate layout design. Second, the gate work function control method is accomplished by local ion implantation. For our experiments, $0.18{\mu}m$ 20 V class HV CMOS technology is applied for HV MOSFETs fabrication. From the measurements, both proposed methods are very effective for elimination of the inverse narrow width effect (INWE) as well as the subthreshold hump.

This paper was applied space harmonic method as a characteristic analysis technique for slotless PMLSM. There is advantages of active response to the change of design parameters as well as reduction of the calculation time. The method can be overcome disadvantages of finite element analysis that needs long times calculation, repetitions of pre and post-process. In this paper, 3D-space harmonic method was applied to consider the precise description of end turn coil shape and the changes of characteristic according to changes of length of z-axis direction. The thrust of optimal design was performed using genetic algorithm to enhance the thrust which is the disadvantage of slotless type PMLSM. For design parameters, width of permanent magnet, width of coil, width of coil inner and lengths of z-axis direction were selected. For objective functions. thrust per weight. thrust per volume. multi-objective function was selected.
