The purpose of this study is to examine the functionality with improved pattern-design working uniform(protocol, P) and current working uniform(control, C). Movement functionality evaluation of improved pattern-design working uniform was carried out through sensory evaluation of working uniform. Movements for the sensory evaluation consisted of four types of up and down and horizontal movements of the shoulders, four types of waist movements and five types of knee movements. The results have been shown as follows: The sensory value of back girth, wrist, side seam area of the "P" with the posture of raising an arm forward up to $90^{\circ}$ and the maximal arm's vertical movement significantly improved compared to the "C". Therefore, it can be concluded that movement functionality was increased with the improved pattern-design working uniform in the respect of arm's up and down movement. Furthermore, for P, Movement functionality improvements were shown in P with arm's horizontal movement, waist bending movement, and knee movement. Current working uniform(C) is jumper-type which wa designed without consideration for movement functionality of the arms and legs. But Pattern-design uniform(P) which was developed in this study. Therefore, the more patterns development, the better movement functionality in working uniform. The improved movement functionality improvements in working uniform will provide not only personal pleasantness but also efficiency of productivity at construction sites. In respect of human body's movement, further study for improved working uniform is required.

This study discusses and demonstrates the structural stability of highly ordered Pt patterns formed on a transparent and flexible substrate through the process of nanotransfer printing (nTP). Bending tests comprising approximately 1,000 cycles were conducted for observing Pt line patterns with a width of $1{\mu}m$ formed along the direction of the horizontal (x-axis) and vertical (y-axis) axes ($15mm{\times}15mm$); and adhesion tests were performed with an ultrasonicator for a period greater than ten minutes, to analyze the Pt crossbar patterns. The durability of both types of patterns was systematically analyzed by employing various microscopes. The results show that the Pt line and Pt crossbar patterns obtained through nTP are structurally stable and do not exhibit any cracks, breaks, or damages. These results corroborate that nTP is a promising nanotechnology that can be applied to flexible electronic devices. Furthermore, the multiple patterns obtained through nTP can improve the working performance of flexible devices by providing excellent structural stability.

작업기억의 읽기 범위에 따른 개인차가 무관련 정보의 억제과정에 작용하는 과정을 살펴보기 위해서 두 개의 독립적인 실험을 실시하였다. 실험 1은 탐사재인과제을 사용하였으며 작업기억 범위가 작은 폭 집단에 비해 큰 폭 집단에서 관련정보의 촉진적 활성화 기제보다는 무관련 정보의 선택적 억제기제가 잘 작동한다는 결과를 얻었다. 실험 2의 어휘판단과제에서도 동일한 결과를 보였으며 두 실험 모두 큰 폭 집단이 작은 폭 집단에 비해 기억부담의 영향을 받지 않는다는 공통된 결과를 얻었다. 이러한 결과는 억제가 작업기억 개인차를 설명하는 중요한 요인임을 시사해준다.

Objective: In order to investigate the functional brain anatomy associated with verbal and visual working memory, functional magnetic resonance imaging was performed. Materials and Methods: In ten normal right handed subjects, functional MR images were obtained using a 1.5-T MR scanner and the EPI BOLD technique. An item recognition task was used for stimulation, and during the activation period of the verbal working memory task, consonant letters were used. During the activation period of the visual working memory task, symbols or diagrams were employed instead of letters. For the post-processing of images, the SPM program was used, with the threshold of significance set at p < .001. We assessed activated brain areas during the two stimulation tasks and compared the activated regions between the two tasks. Results: The prefrontal cortex and secondary visual cortex were activated bilaterally by both verbal and visual working memory tasks, and the patterns of activated signals were similar in both tasks. The superior parietal cortex was also activated by both tasks, with lateralization to the left in the verbal task, and bilaterally without lateralization in the visual task. The inferior frontal cortex, inferior parietal cortex and temporal gyrus were activated exclusively by the verbal working memory task, predominantly in the left hemisphere. Conclusion: The prefrontal cortex is activated by two stimulation tasks, and this is related to the function of the central executive. The language areas activated by the verbal working memory task may be a function of the phonological loop. Bilateral prefrontal and superior parietal cortices activated by the visual working memory task may be related to the visual maintenance of objects, representing visual working memory.

대상을 상징하는 기호로서의 의미를 포함하고 있는 기하학적 패턴은 조형표현에 있어서 20세기 이후 예술가들의 작품을 통해 재구성되어 현대적인 이미지를 나타내는 중요한 모티브가 되고 있으며 패턴의 단순하고 간결한 형태는 외형뿐만 아니라 문양 장식을 통하여 새로운 아름다움을 창출하고 있다. 기하학적 패턴의 문양장식은 단순화되고, 이성적이며 현대적인 세련미와 잘 어울린다. 이렇듯 기하학적 패턴을 활용한 문양은 팔각형, 반원, 삼각형, 사각형 등의 기하학적 도형들을 이용하여 단순한 미로 현대인에게 만족감을 준다. 또한, 기하학적 패턴은 규칙적이고 단순명료하여 시각적으로 강렬한 효과를 유도하며 운동감과 속도감이 주는 역동성으로 3차원적 공간감으로 확장되기도 한다. 이로 인해 주목성이라는 특성이 나타나는데 테이블웨어에서도 이러한 기학학적 패턴을 이용한 디자인은 강한 주목성으로 시각적인 즐거움을 준다. 또한 이는 우연성의 요소에 근거해서 만들어지는 형태가 아니기 때문에 객관화될 수 있으며 반복적인 재현이 가능하다. 이러한 반복구성은 테이블웨어를 만드는 많은 디자이너에게 영향을 줄 수 있으며 테이블웨어 디자인을 더욱 더 고급화하여 도자 산업에 고부가가치를 창출할 수 있는 새로운 가능성을 제시할 것으로 생각된다.

In this paper, a new simulator of the biped robot for planning walking patterns was showed. And this simulator(MHBiped) is able to not only visualize the plan of patterns but also verify whether a biped robot design is suitable. In addition, MHBipd can modify various kinds of walking parameters and the trajectory of biped robot. Therefore, a new biped robot can be designed easily by the this simulator before you apply to a robot. As a result, a well-balanced parameters of walking patterns watching the movement of CG and ZMP can be obtained. Walking patterns should be changed according to both the existence of obstacles and conditions of ground and it can be described by the trajectory of hip and ankles. All those trajectorys can be also obtained by the cubic spline functions and the way of modeling walking patterns. The results of simulator, the movement function of CG and ZMP, the cubic spline functions and modeling of biped robot were introduced in this paper. And the effectiveness of this simulator was confirmed by the simulations.
