In this paper, we improve the matching impedance of antennas by inserting parasitic slots on the ground plane of right-angle triangular slot antennas. The designed antennas characteristics are analyzed by using Finite Different Time Domain (FDTD) method, the specific design frequency is 10 GHz and match impedance is 50 ohms. Simulation results show that the efficient of return loss and radiation patterns are improved and enhance. In this case, the right-angle triangular slot antennas with parasitic slots have matching impedance better than antennas without parasitic slots.

The purpose of this study is to investigate the influence of the suitability of the chronic regulatory focus and the advertising message type on the evaluation of the beauty product. In addition, feeling right while and individual is reading an advertisement is measured to check the mechanism making the regulatory fit effect. The experimental design was designed with the mixed design of 2(chronic regulatory focus: promotion / prevention, between group) ${\times}$ 2(advertising message type: promotion /prevention, within a group). 100 female university student subjects in their twenties in Seoul and in the metropolitan area were asked to respond to questionnaires in the study. The reliability analysis, T-test, analysis of variance(ANOVA), and analysis of covariance (ANCOVA) on the collected data were done with SPSS WIN 12.0. The results of the study are as follows. First, the regulatory fit effect that when the individual chronic regulatory fit corresponds to the advertising message focus each other in the advertising of a new beauty product, the evaluation on the product is more positive could be checked. The promotion focus message of shampoo, the promotion focus group showed more positive response than the prevention focus group and as for the prevention focus message, the prevention focus group showed more positive results than the promotion focus group so that the effect of regulatory fit appeared. Second, when the regulatory fit effect appeared in the evaluation on the new beauty product, the fit effect on the individual chronic regulatory focus and on the advertising message focus also appeared in the measurement of feeling right. Hence, feeling right could be checked by using the mechanism of the regulatory fit effect.

The aim of this study is to develop and suggest the handle for lockers according to the design process which are used for keeping of student's personal stuffs such as books, writing implements and gym uniform in elementary, middle and high school and university as well. This includes the design development for ILGUMTUR which is specialized for office furniture, but does not own the intellectual property right yet. The design concept based on the domestic locker market survey is recessed handle at low- to intermediate price and it's material should be plastic what is solid and light. The lock system should be constructed by molding process and the name plate can be exchanged every time the owner of locker changes. Contrary to the right angle of it's external appearance, the handle of the locker is designed to be softly round and the simplicity is pursued for an easy production. On the basis of this design concept the sketch has been drawn and upgraded in full by 3D-rendering. Then the mock-up has been completed by 3D printer and ILGUMTUR has obtained a patent for the locking system based on the rotation of 2 circles.

본 연구는 시각적 등가성에 대한 한국인의 성향분석을 목적으로 수행되었다. 자연현상에서 흔히 조우할 수 있는 시각적 동등성에 우리가 동일한 가치를 부여할 수 있는지 없는지에 대해 일부 심리학자들의 유사연구를 참고로 하였고, 설문조사를 통해서 한국인의 성향을 조사하였다. 그 결과는 다음과 같은 발견점을 가져다 주었다. - 일부 특수한 경우를 제외하고 시각적 등가성은 한국인에 있어서는 현실적으로 존재하기 어렵다. - 화면에서의 대각선은 오른쪽 아래에서 왼쪽 위방향보다 왼쪽 아래에서 오른쪽 위방향으로 보다 상승감을 느끼게 해준다는 지적은 사실로 드러났다. - 화면의 오른쪽이 왼쪽보다 무거워보인다는 지적은 우리 나라 사람들에게 있어서는 확인되지 않았거나 무시할만한 정도 이내이다. - 자연현상의 묘사나 이에 대한 관찰자의 시각물 수용에서, 사용자 인터페이스가 작용하는 것으로 드러났다. 이 경우 오른손 듣기가 대부분인 한국인에 있어서는 이러한 현상을 자연스러운 것으로 받아들이는 것이 좋다. - 한국인의 좌측 우위사상에서 오는 전래적인 시각적 표현은 지금도 우리 문화 속에 녹아 있다. 이상의 내용을 한 마디로 정리한다면, 한국인에 있어서 시각적 등가성은 대체적으로 실존하지 않는다는 점이며, 여러 가지 측면에서 오른쪽보다는 왼쪽에 경도되는 일반적인 성향을 한국인이 가지고 있다는 점이 발견되었다.

The analysis of spatial search direction and its concentration through eye movement can produce some useful data in that it enables to know the features of space elements and their effects on one another. The results by analysing the search features and concentration of spatial sections through the eye-tracking in shops in a department store makes it possible to define the followings. First, the features of 'eye's in & out' could be estimated through the division of sections by the characteristics of those shops and the extraction of central point based on the decision of continuative observation. The decision of continuative observations enabled to analyse the frequency of observation data which can be considered to be 'things watched longtime' and the stared points that is equivalent to 'things seen very often', by which the searching characteristics of spatial sections could be estimated. Second, as with the eye's [in], the right shops had 0.6 times more (3.5%) than those left and as with the eye's [out] the left ones had 0.6 times more (3.5%). It indicates that [in, out] of the right and the left shops had the same difference, which lets us know that with starting point of the middle space, [in] and [out] were paid more attention to the right shops and the left shops respectively. Third, as with the searching directions by section, the searching times [2.9 times] from [B] to [A] were than that [2.6 times] from [A] to [B]. It was also found that the left shops had more searching direction toward [C, D] than the right ones and that those searching activities at the left shops were more active. Fourth, when the searching directions by section are reviewed, the frequency of searching from [B] to [A] was 2.9 and that of the other way 2.6. Also the left shops were found to have more searching direction toward [C, D] than the right ones and those searching activities at the left shops were estimated to be more active.

항공기, 자동차를 포함하는 모든 수송수단 설계에 있어서 내추락성 설계가 강조되고 있으나, 심각한 부상 또는 사망으로 이어지는 사고는 지속적으로 발생해 왔고, 앞으로도 발생할 것이다. 심지어 생존 가능으로 분류되는 사고에서조차도 상당한 수준의 인명사고가 있어 왔음은 주지의 사실이다. 그러나 이러한 사고들이 반드시 불가피하다고만 할 수는 없다. 만약 좌석, 구속장치, 탑승공간 강도조건 등 탑승자 보호계통이 적절히 또는 바르게 설계된다면 추락상황에서의 생존성은 획기적으로 증대될 수 있다. 이를 위해서는 급격한 가속도 변화환경에서의 인체 허용한도 특성을 충분히 이해해야 하며, 이를 바탕으로 인체 허용한도 제한치 이내에서 하중조건이 유지되도록 탑승공간을 설계하여야 한다. 본 논문에서는 급격한 가속도 변화환경에서의 인체 허용한도의 중요성과 예측되는 추락환경 변화에 따른 설계요구도 변화 필요성을 강조함으로써 내추락성 설계에 대한 공감대를 넓히고자 한다.

Drones can be manipulated in a variety of ways. One of the most common controller is joystick method. But joystick controller uses both hands and takes a long time to learn. Particularly, in the case of 8-character flight, it is necessary to use both front and rear flight (pitch), left and right flight (Roll), and body rotation (Yaw). Joystick controller has limitations to intuitively control it. In particular, when the main body rotates, the viewpoint of the forward direction is changed between the drones and the user, thereby causing a mental rotation problem in which the user must control the rotating state of the drones. Therefore, we developed a motion matching controller that matches the motion of the drones and the controller. That is, the movement of the drone and the movement of the controller are the same. In this study, we used a gyro sensor and an acceleration sensor to map the controller's forward / backward, left / right and body rotation movements to drone's forward / backward, left / right, and rotational flight motion. The motor output is controlled by the throttle dial at the center of the controller. As the motions coincide with each other, it is expected that the first drone operator will be able to control more intuitively than the joystick manipulator with less learning.

In this study, weight carrying pattern analysis and comparison method of four foot region were suggested. We used three types of club(driver, iron7, pitching wedge). This analysis method can compare between top class golfer and beginner. And the comparison data can be used to correct the swing pose of trainee. If motion analysis system, which can measure the swing speed and instantaneous acceleration at the point of hitting a ball, is combined with this plantar foot force analysis method, new design development of golf shoes to increase comfort and ball flight distance will be available. 1. Regional change of force acting, in address, is evenly distributed on both feet. In back swing top, 76% on right foot, 75% on left foot as impact, and 86% on left foot as finish. As regional force acting, in address, pros get high marks on rare and inside of right foot and rare and outside for amateurs. In back swing top, it is higher as fore and inside of left foot, pros as rare part of right foot and amateurs as forefoot. In impact, it is higher for pros and amateurs in outside and rare part of left foot and fore and inside of right foot. In finish, for both pros and amateurs, it is higher for outside and rare parts of left foot. 2. For each club, forces are evenly distributed on both feet in address. In back swing top, the shorter a club is, the higher impact on right foot and the higher finish distribution on left foot. For all the clubs used, in each region, pros get higher on rare and inside of right foot and as amateurs on rare and outside of left foot in address. In back swing top, for all clubs, pros get higher on rare and outside of right foot as fore and outside for amateurs. In impact acting, for all clubs, rare and outside of left foot get higher. In finish, force concentrates on rarefoot. 3. On both feet force, right foot forces of amateurs is higher than those of pros in back swing top. In impact and finish, pros get higher on left foot.
