This paper presents a novel multiband microstrip-fed right angle slot antenna design technique for multiple independent frequency bands. The new technique uses various slot sizes at various appropriate positions. We first propose a tri-band slot antenna consisting of three right angle slots. Then, a quad-band slot antenna is developed with four right angle slots which achieves slant ${\pm}45^{\circ}$ linear polarization, omnidirectional pattern coverage, good antenna gain, and acceptable impedance bandwidths over all the operating frequency range. Moreover, an open-circuited tuning stub is introduced to achieve good impedance matching. Both proposed antennas are designed on a ground plane of RT/duroid 5880 substrate with a thickness of 1.575 mm. The real measurable results show that the desired frequencies used in wireless communication systems, namely, WLAN and WiMax, are efficiently achieved.

This paper presents a novel balanced filter design based on a metamaterial structure applicable to differential-mode excitation. The metamaterial structure is based on a unit-cell which under a differential-mode excitation behaves like composite right/left-handed(CRLH) metamaterial with filter characteristics. In contrast, the metamaterial unit-cell is below cut-off under a common-mode excitation. Experimental results are used to verify the proposed metamaterial's differential-mode characteristics. The metamaterial is fabricated with a balanced filter design resulting in an operating frequency range of 960~1000 MHz with a insertion loss of 4.1 dB.

The purpose of this study is to develop the applied brassiere pattern of women which are fitting for 75A. The constructing of this experimental brassiere were lower cup, upper cup, front panel and U-wing as well as a full cup embcing the entire breasts. Basing on the bra model from domestic experiment results, development of an applied design, round side type pattern, has been suggested. Thus, suggesting the round variation design bra, which is an applied design based on the basic model based on the breast volume. Based on the sizes that are in reference to Size Korea (2004) and related previous researches, the basic model that has been experimented with 11.4% polyurethane and 88.6% Nylon as the materials, has been selected as the model of research. This takes 75A, the size of which is set according to the underbust circumference and the breasts circumference, as the basic model. It is an application in terms of design, and there is no change to the cup volume or size because it has been moved only from the cutting line. The applied design changes the right side of the lower cup into an easily-movable form and attaches it to the upper cup, and the lower cup takes the right part of the upper cup to form a cup shape of round variation design. It also changes basic straight form of the wings, and alters them into U-shape.

The purpose of this study is to investigate the characteristics of electroencephalogram (EEG) during emotional occurrence of likes and dislikes in humans subjected to visual stimuli. Fifteen healthy male subjects participated in the study. Portrayals of females and cars on a visual screen, one photographic display at a time. were used as the stimulus. The subjects, with their EEGs concomitantly monitored, were asked to record their likes and dislikes for each portrayal of a total of 50 sequential displays. The results indicated that beta ($\beta$)=wave was more prevalent with dislikes than likes, and the arousal level was higher when dislikes predominated over likes, implying that more cerebral information processing activity was involved in answering dislikes than likes. In the case of cars, the difference between likes and dislikes was focused within a frequency band of 15-20 Hz in the right cerebral hemisphere. Our findings suggest that the activity in the right brain predominates with increases in negative emotion.

The protection of intellectual property right in international conventions are worldwide or regional areas already exists a century. Therefore, our country is positive affiliated with international conventions. After that time, such as a violation of international convention and an example of imitations are continually that we prognosticate the international trade market activities was difficult not only became an issue of country credit risk. At this point, the major purpose of this study make an analysis of both paralleled with the case study follow an example and the comprehension with concerned about recognition of intellectual property right. In additionally, it stands a plan of package design protections under the WTO systems. This study have carried out a theoretical and practical analysis of intellectual property right and statistical analysis through the inside and outside of the country packaging design study and a case study of troubles with intellectual property. Besides, it is accomplish the purpose of the study that established exploratory study survey about inside and outside of the country packaging design infringement case study and relative package design industry employees with consumptions real research. I hoped that this study will be a foundation on which packaging, design industry protections to intellectual property right.

Recently, the point of view about housing environment in the city has changed from the traditional point of view of the center of housing to the subject of land- utilization-control for interaction of buildings. Right of light is the center of this issue in other words. Also many interests about the beauties of the city have increasing centering around Europe etc. This is to change a city design into the characteristic design from the exiting uniform design. As if reflect this situation, recently we are setting up the night illumination and constructing a building which acted as Land Mark like the Jong-Ro Tower. And Apartment Housing was being built various form deviate from a existing standardized form and skyline. Existing studies about sunshine of Apartment Housing have dealt with just about a standardized Apartment Housing form. So this study analyzed a recently increasing interest for Right of light and change of sunshine environment on Apartment Housing which have a various skyline form.

This research alms to understand the residents' actual conditions and reasons for remodeling in order to search for the desirable participation design methods, under the assumption that the remodeling of apartments by their current residents is a problem. The subjects of this research are residents of mixed-used apartments supplied via the fitting form housing supply methods recently. The results are shown below. First, the reasons for remodeling by the current residents we expansion of Interior space and change in interior atmosphere. Positive participation of the residents in the design decision is high and this remodeling problem is easily solved. Second, based on the Habraken's SAR theory, supports units and variable units were separated and in each process rational and systematic design methodologies according to the role and responsibility of the residents were observed. Third, considering the great level of remodeling right before moving in, there is a need for the variable housing supply methods of residents to easily participate in the design, construction, and supply of the apartments. Through the participation of the residents In the apartment design process will not only solve the problem of repeated apartment remodeling, but also accommodate the various needs of the residents.

This study is about the structure and transition of orthogonal design of palace architectures in Joseon Dynasty. The results are as follows. First, Changdeokgung and Changgyeonggung Palaces' corridors, and their architectures seen in the Court Documentary Paintings have early Joseon style in the corner-connections. Their roof shape in the corner is gable roof. Generally, gable roof has direction. Besides, it is easy to extend gable sides. Second, Corridor of Gyeongbokgung Palace has hipped and gable roofs with corner eaves. It was popular during the late Joseon Dynasty. On the other hand, it is impossible to extend any sides of those roofs since they have roof faces in their four sides. Instead, they have completeness. That's why their aesthetic appeal exhibits more pleasing than gable roofs. Third, corner-connections of palace architecture shows evidences and traces of the transition from gable roofs meeting at right angle in the early Joseon to hipped and gable roofs meeting at right angle with corner eaves in the late Joseon. Also, the corner-connections with corner eaves were usually used even in the attached architectures.
