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.

This study was conducted to analyze the Korean inclination to visual equivocality. Similar studies conducted by several psychologists were reviewed in order to determine whether we can put equal value on the visual equivocality which is often shown in natural appearance. This Korean inclination was also investigated with the help of a public survey. The following conclusions were derived from the study. - In reality, there is no visual equivocality for Koreans except in some specific cases. - It is true that, on a screen, a diagonal line from the lower right to the upper left produces a stronger feeling of upward tendency than one from the lower left to the upper right. - The idea that the right side of a screen looks heavier than the left one was not supported and should be rejected for Koreans. - It was discovered that the user interface is working when a person is describing a natural appearance or looking at a description. This fact is generally accepted for Koreans, the majority of whom are right-handed. - Until now, the idea of a Korean superiority toward the left side in visual expression has been found in our culture. In short, it was uncovered that Korean people generally do not have visual equivocality but, instead, have an inclination to left side rather than the right from various aspects.

The purpose of this study is to examine that the escape stair of high-rise buildings has to be designed as a left-handed stair(a stair being designed to turn left whicle we go down the ground floor) judging from fire-safety point of view. Most of Korean people are right-handers. In case of right-handers it was found that the occupant's escape speed using a left-handed stair is more convenient and fast than of a right-handed stair(a stair being designed to turn right while we go down the ground floor). But most of the escape stair of high-rise buildings in Korea was designed as a right-handed stair. The fire code therefore should be provided that the escape stair of high-rise buildings should be a left-handed stair.

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.

Design with crashworthiness concept has been emphasized for almost aircraft and motor vehicles. However, crashes accompanied serious injury and death have been continuously occurred, and will be occurred subsequently. What was worse, it is a well-known fact that there were a good many crashes classified as survivable accidents in which fatal injuries were reported. But we cannot say that fatal injuries were inevitable consequences of those crashes. If crashworthy design for seat, restraint systems, and cabin strength were adequate or right, survivability in a crash event could be maximized greatly. To substantiate the right crashworthiness, we must thoroughly understand the characteristics of human tolerance under abrupt acceleration change, and the cabin design should be combined with proper use of energy absorbing technologies that reduce accelerations experienced by the occupants. In this paper, the emphasis on the human tolerance under abrupt accelerations as well as the necessity of change in design requirements for crash environment will be stressed to widen the belt of consensus for the right crashworthy design.

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.
