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.

The purpose of this study was to obtain the basic data for sound wear design. The objects' of this study were 331 women's university students. The eight items were the shoulder length, shoulder slope, height, weight, chest girth, neck girth, back length, and back shoulder width. The shoulder length and slopes were measured, compared with the right, the left, and other items. The results were as follows; The difference between the right and left shoulder length did not nearly appear. The mean of the right shoulder slopes was $21.3^{\circ}$, and that of the left was $21.9^{\circ}$. According to increase of the age, the right and left shoulder slope tends to be higher. The maximum distribution was $20.7^{\circ}$. According to increase of the age, the maximum distribution tends to be higher. The left compared with the right shoulder length, the right shoulder length of 90.3% objects' was longer than that of the left. The right and left shoulder length of 4.2% objects' were same. The left shoulder length of 5.4% objects' was longer than that of the right. The left compared with the right shoulder slopes, the right shoulder slopes of 12.7% objects' were higher than those of the left. The both size of 20.5% objects' were equal. The left slopes of 66.8% objects' was higher than those of the right.

A novel frequency multiplier using composite right/left-handed transmission line is proposed. The left-handed transmission line in the proposed frequency multiplier suppresses the fundamental component($f_0$), while the composite right/left-handed ${\lambda}/4$ open stub diminishes unwanted harmonics. Due to the combination of the left-handed transmission line and composite right/left-handed ${\lambda}/4$ open stub, the only desirable multiplied frequency component such as 3 $f_0$ and 4 $f_0$ are obtained at the output port excellently. For the example of the proposed design, frequency multipliers are designed at 1 GHz of $f_0$ and measured. The measured output power of 3 $f_0$ and 4 $f_0$ is -5.67 dBm and -6.43 dBm, respectively, when the fundamental input power was 0 dBm.

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.

In this paper, we present the 8 port in-phase power divider using right/left-handed transmission line. The proposed power divider splits the input power into 8 port regardless of the electrical length of transmission lines. Its size is much smaller than the conventional one. As the length of the transmission line in the power divider decreases, its bandwidth becomes wider.

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.

Purpose: The purpose of this research is to induce domestic eyewear industry to invest in research and development of eyewear manufacturing technology and eyewear design. Methods: Analysis of Industrial Rights using data issued by Korea Intellectual Property Office and search results by 'Kipris' (Korea Intellectual Property Rights Information Service). Results: A number of Industrial Rights Application related to eyewear of eyewear industry has rapidly increased since 1980's. The ratio of Patent and Design Right applications related to eyewear by foreigner has continually decreased, 55%, 32.9% in 1980's, 40%, 22% in 1990's and 27%, 13.9% in 2000's. This shows domestic eyewear industry has developed technology and design on eyewear more and more. But numbers of Design Right applications in 1990's were about 60 in a year and those in 2000's were about 70 in a year. This may explain a few eyewear company have applied for Design Right. Conclusions: It is evident that domestic eyewear industry make an more effort and investment to develop eyewear manufacturing technology and design, but not enough. Actually, we don't know exactly how they develop and how much they invest. Now we need to research problems what they have and environments what they face.
