Objectives: This research intends to comprehend the relation of figure cognition, self-esteem and vocational anxiety perceived by nursing students then, test the mediator effect of self appearance esteem in the relation of vocational anxiety and figure cognition. Methods: This research conducted a survey targeting 240 female university students in their senior years in 3 nursing universities with 4-year curriculum. The collected data is from the average and the SPSS / WIN 21.0 calculated standard deviation. The analyzed correlation was used to route using model AMOS 20.0. Results: As a result of conducting the Sobel Test, that figure cognition affects vocational anxiety, mediating and self appearance esteem, vocational anxiety was shown to have decreasing mediation effect (-3.827, p<0.001). Conclusions: The Anxiety of Nursing Students at Work requires developing an intervention program for improving the appearance, self-esteem and positive body awareness.

This paper proposed a sizig system for men's jackets in order to improve the clothing fitness and rain the productivity. The sizing system was classified according to 3 age groups. Figure types were categorized by shoulder angle and body shape. The size interval of the basic dimensions was established at regular intervals centering around their means. Altogether, 15 size charts were developed based on the frequency distribution. Size designating measurements for jackets were height, chest girth and waist girth. Size intervals were 3cm for chest and waist girth, 5m for height, and 2cm for waist and hip girth. Considering the cover factor, charts with a limited number of sizes were suggested with necessary measurements for each figure type of each age group.

Both the X-ray diffraction data of the normal direction in the sample orientation and the pole figure data of three reflections, (111), (200) and (220), were used to do the Rietveld refinement for the copper sheet prepared by a cold rolling process. The agreement between calculated and observed patterns was not satisfactory, which was attributed to the preferred orientation effect of the copper sheet. The Rietveld refinement for the copper sheet could be done successfully by applying the pole density of each reflection obtained from the corresponding inverse pole figure to the X-ray diffraction data of the normal direction. The R-weighted pattern, $R_{wp}$ was 12.99% and the goodness-of-fit indicator, S, was 3.68.

In the paper, we confirmed improvement Noise figure of the entire RF front-end using spiral inductor with PGS(Patterned Ground Shield) and current bleeding techniques. LNA design is to achieve simultaneous noise and input matching. Spiral inductor in input circuit of LNA inserted PGS for betterment of Q-factor. we modeling inductor using EM simulator, so compared with inductor of TSMC 0.18um. We designed and simulation the optimum structure of PGS using Taguchi's method. We confirmed enhancement of noise figure at LNA after substituted for inductor with PGS. Mixer designed using current bleeding techniques for reduced noise. We designed LNA using inductor with PGS and Mixer using current bleeding techniques, so confirmed improvement of noise figure.

Micro-abrasive jet machining(${\mu}AJM$) using mask is a fine machining technology which can carve a figure on a material. The mask should have holes exactly same as the required figure. Abrasive particles are jetted into the holes of the mask and it collide with the material. The collision break off small portion of the material. And the ${\mu}AJM$ nozzle should move all over the machining area. However, in general the carving shape is modeled as in a bitmap figure, because it often contains characters. And the mask model is also often modeled from the bitmap image. Therefore, the machining path of the ${\mu}AJM$ also efficient if it can be generated from the bitmap image. This paper suggest an algorithm which can generate ${\mu}AJM$ tool path directly from the bitmap image of the carving figure. And shows some test results and applications.

교과서에서는 도형 f(x, y) = 0을 x축 방향으로 a만큼, y축 방향으로 b만큼 평행이동한 도형의 방정식을 구할 때 도형 f(x, y) = 0 위의 임의의 점을 점 (x, y)로, 평행이동 된 도형 f(x-a, y-b) = 0 위의 점은 점 (x', y') 로 표현하고 있다. 도형 f(x, y) = 0 위의 임의의 점을 점 (x, y)로 표현한다면 점 (x, y)와 도형 f(x, y) = 0은 다른 대상인데 같은 문자들이 사용되어지고 있다. 본 연구에서는 이러한 교과서의 표현이 50년 넘게 고수되어, 학생들의 사고가 경직되므로, 개선이 필요하다고 보고 다음과 같이 연구한다. 첫째, 공식을 유도할 때, 도형 위의 임의의 점을 교과서와 달리 표현했을 때의 학생들의 반응은 어떠한가? 둘째, 살펴본 결과를 바탕으로 교과서 표현을 어떻게 수정할 것인가? 셋째, 수정한 표현에 대해 학생들은 어떻게 반응하는가? 그 결과 도형 위의 임의의 점을 교과서와 달리 표현하고 평행이동 된 도형 위의 점을 점 (x, y)로 두었더니, 조사한 학생들은 모두 본 연구에서 개선한 설명이 더 쉽다고 응답하였다.

This study aimed at studying the sequence of the Figure Transformation Learning, inquiring relationship among these transformations and then researching whether there is the difference of the learning ability or not between by teaching them as it is independent and by teaching them as it is contains. (Hypothesis 1) It may be more effective to teach The Sequence of Transformation Learning by beginning with peculiar field, ending with general field than vice versa At the result of verification-C $R_{M}$=2.59, 0.005$R_{M}$=5.19, p<0.005-significant difference appeared. It is proved more effective to teach the Figure Transformation Learning the way it contains than the way it is independent. Synthesizing two hypothesises of the above, the conclusion is following The Figure Transformation Learning should be taught by beginning with peculiar field. ending with general field (congruent transformationlongrightarrowsimilar transformationlongrightarrowprojective transformationlongrightarrowtopological transformation). To teach it the way it contains is more effective.ive.

연구자는 직각으로만 이루어진 계단 모양의 둘레를 구하는 과정에서 이미 알고 있는 직사각형의 둘레를 구하는 방식을 활용하지 못하고 어려움을 겪는 모습을 보았다. 이에, 평면도형의 둘레에서 학생들이 어떠한 어려움을 겪고 있는지 확인하고 어려움을 겪는 학생들을 도울 수 있는 방법을 찾고자 하였다. 이를 위해 평면도형의 둘레 문제에 관한 다수 학생의 기록지를 분석하고, 그들 중 일부를 대상으로 면담을 수행하였다. 그 결과 학생들은 둘레를 구하기 위해 주어진 정보의 인식과, 그것을 해결에 필요한 정보로 전환하는 두 측면 모두에 어려움을 겪고 있으며, 둘레가 길이의 속성을 갖는다는 선행지식도 적절히 구성되어 있지 않음을 알 수 있었다. 이러한 결과를 토대로 이 연구에서는, 평면도형의 둘레 문제해결을 돕기 위한 지도방안을 제안하였다.

레이다에서 도플러 측정과 MTI(Moving Targer Indicator), 고해상도 등의 기능을 수행하기 위해서는 송신 및 수신회로 전체가 코히어런트 시스템으로 동작하여야 한다. 본 논문에서는 코히어런트로 동작하는 레이다의 송수신단을 설계하기위해 TWTA(Traveling Wave Tube Amplifier)와 STALO(Stable Local Oscillator) 및 COHO(Coherent Oscillator)를 사용하였으며, 설계된 수신단에서의 잡음지수를 계산하였다. 계산된 잡음지수로 레이다 방적식을 이용하여 각 송신모드별로 최대 탐지 거리를 산출하였다.

The center of gravity of a triangle is the center of a physical shape. This is the content in the second grade of middle school, 'The Use of Similarity'. Unlike the cases of circumcenter and incenter, which are easily recognized visually, it is not easy for teachers to guide students with the visual meaning of center of gravity. According to the survey results, students, regardless of academic achievement, grade, and major, perceived the center of gravity of various plane figure as the center of their shape within a limited area through visual judgment. With reference to the results and contents of this process, it is hoped that the point of the three medians is meaningful not only in argumentative definition that the intersection of the triple line is the center of gravity of the triangle, but also in the center of a figure.
