Objective: The purpose of this study is to identify the effects of sign language video location in e-learning system for the hearing-impaired. Background: E-learning education is a good way to resolve the inequality of education for the disabled. Providing a sign language video in e-learning education for the hearing-impaired is very important for their learning. Although the location of sign language video is an important factor in the design of the video, the effect of its location in learning using the e-learning system was not studied. Method: In order to identify the effect of sign language video location on the learning of the hearing-impaired using the e-learning system, the prototypes of the system with different locations were developed. Eighteen people with hearing impairment participated in this experiment. Learning presence, learning immersion, and learning satisfaction were used to measure learning effects with sign language video location. Results: Bottom right position was more preferred through preference evaluation for sign language video location. The learning effect with sign language video location (bottom-left and bottom-right) was not significant. That is, the effects of learning presence, immersion, and satisfaction were not statistically significant with video location. Conclusion: From this study, the following have to be considered in e-learning system design for the hearing-impaired. Although the location of a sign language video is not a significant factor from the experiment, the bottom right position in the design is proposed because learning presence and satisfaction is slightly higher at the bottom right position, and the position is preferred from subjective evaluation. From the analysis of interview data, it was also proposed that the design of a sign language video should be improved for the hearing-impaired. Application: The result of this study can be applied to the e-learning system design for the hearing-impaired.

The distinctive design of apparel product is the crucial factor that provides the powerful competitive advantage and customer satisfaction. However, knock-offs or copycats easily copy the design of apparel product and its problem tends to be assented in real world. Design right is one of intellectual property rights that would be produced by intellectual activity and the appropriate means to establish the exclusive rights to the design should be established. Legal protection to the design right is the system that can prelude copycats from eroding an exclusive position in the market place. The present study was to analyze the trend of registration of design rights in apparel products and to point out problems of current protection law to design.

In this paper, a unit cell for low pass filter design by using composite right and left-handed transmission line in conductor-backed coplanar waveguide is proposed. The characteristics of the unit cell are analyzed in order to design a low pass filter in small sizes. By changing the sizes of the unit cell, the parameters of right-handed and left-handed immittance components are changed and the desired characteristics of the unit cell are achieved. The equivalent circuit of the unit cell is extracted and analyzed either. As a result, the simulation results of the unit cell and the equivalent circuit are almost identified. The movement and energy distributions of electromagnetic field are shown to confirm the property of the unit cell. In the end, a low pass filter is demonstrated by cascading three proposed unit cells, which shows cutoff frequency of 1.53GHz and deep attenuation from 2.23GHz to 4.49GHz lower than -50dB.

본 논문에서는 composite right/left-handed 전송 선로를 이용한 주파수 체배기를 제안하였다. 제안된 주파수 체배기의 left-handed 전송 선로는 기본 주파수($f_0$) 성분을 억압하였고, composite right/left-handed ${\lambda}/4$ 개방 스터브는 원하지 않는 고조파 신호 성분들을 제거하였다. Left-handed 전송 선로와 composite right/left-handed ${\lambda}/4$ 개방 스터브를 조합하여 사용함으로, 오직 3차 및 4차 고조파와 같은 원하는 고조파 신호들만을 효과적으로 얻을 수 있었다. 본 논문의 타당성을 보이기 위해 기본 주파수를 1 GHz로 하는 주파수 체배기를 설계하고, 측정하였다. 설계된 주파수 체배기의 입력 전력을 0 dBm으로 하였을 때, 측정된 3차 체배기와 4차 체배기의 출력 전력은 각각 -5.67 dBm과 -6.43 dBm이다.

This research has been carried out with the objects of sporting goods shops to find out what structure of those shops raises more interest from customers. The tracking eyes on the objects which are the same but seen to have different structures has revealed the followings. Customers' visual appreciation of Reverse left/right Images (11.1) was found to be higher than that of Original Images (10.6). Furthermore, the reverse left/right image of the space also was found to attract more interest from customers, which led them to have longer observation. The below is about the interpretation of the spatial exploration by observation time and the appreciation of its visual content in line with the experiment objects of selling spaces. The longer the space was observed, (1)the higher the expansive searching of space was, (2)the more spots were observed as if they did not know what to see after they first observed at early hours, (3)later (in the time range of 64~73 seconds) they came to look at the spots in which they got interested, (4)and then again they suddenly got lost what to see. When the change of observation characteristics by time range is reviewed, it can be seen that the searching of original images is changed from Divergent Feature to Convergent Feature when the observation time increases from the early stage of observation to the later. On the contrary, the reverse left/right images were found to have the opposite searching features, that is, from convergent exploration to divergent exploration. These findings show that the reverse left/right images of the sporting goods shops, which were the experiment objects, have more factors attracting customers' attention and interest and that it is the very shop-structure which makes customers have better visual appreciation of those shops.

The symmetry is general geometric design principal in contemporary architecture shape. But, Symmetry sometimes easily causes unreasonable design. In some reason, two of symmetric units in the apartment, one side of unit have very reasonable plan and arrangement but opposite side unit nay not. For example, if the kitchen on right unit had right-handed arrangement, the symmetrical other would have left-handed kitchen arrangement. In addition to this, if each house unit has the same plan but different direction, each unit has different usage or affects the residents' life pattern. Nevertheless, Architects use only one unit plan to design public housing development by using symmetric operator (mirror, proper rotation, inversion center) at their option. This study suggests that using group theory and mathematical matrix rather than designer's discretion can solve this symmetry problem clearly. And, this study analysis the merits and demerits between each symmetrical pair of unit plan shapes by using mathematical point group theory and matrix.

Purpose The purpose of this study is to find out in extent to which the companies in Korea and oversea, which has been subjected by different laws of their country, have guaranteed the personal information rights and have provided proper 'right to access' to the information subjects. Design/methodology/approach This study compared Korean laws with 'General Data Protection Regulation (GDPR)' of EU and 'California Consumer Privacy Act (CCPA)' to check each of the level of 'right to access' guarantee. In terms of the difference in guaranteeing the right, this study compared Korean IT leading companies with US global leading IT companies to find out how much 'right to access' are properly implemented in their policies and functions they provide. Findings The result of the study shows that 'right to access' has not been well guaranteed by Korean law, as it does not provide the right to choose method and medium by information subjects and does not clarify the types of diverse information. This was clearly opposite with the other laws providing the right to choose what method and medium that subjects want with clarifying every types of personal information possible to be more. In addition, 'right to access' has not been well guaranteed by Korean companies in comparison with by the oversea companies which proactively guarantee the right by setting the function enabling subjects to browse their information through their websites or applications.

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.
