  • This paper pursues a comparative study on the design and function of the ready-made Bo-Son and the Bo-Son Pattern based on teaching and learning materials. It intends to investigate whether the Bo-Son is designed to suit to Kinetics of foot or to give the ease of wearing and taking off. The following results came out through trial wearing. 1) The Bo-Son pattern suggested in teaching materials can not satisfy the wearers with partial modification due to design problem. On the other hand, the ready-made Bo-Son can satisfy them with partial modification. 2) The important factor in designing the pattern of Bo-Son is the posture of foot when putting on it, that is, the height of the heel of the foot from the floor, the length of the heel, the length of toe and the bending angle of toe. 3) As a result of this study, in the design of the improved Bo-Son pattern, it is most suitable when the size of foot is 230mm, the height of the heel of the foot is 12.5cm, and and angle of the front toe of a sock is 35$^{\circ}C$.

  • Purpose: This study aims to analyze the diffusion pattern of the Mongolian mobile phone market. In particular, we used a generalized diffusion model to explore the factors affecting market potenial. Methods: We used three diffusion models to estimate the number of mobile subscribers in Mongolia. Based on the Logistic model with the best fitness, we introduced time-varying market potential and explored the influence of various independent variables such as GDP and inflation. Results: Among the basic diffusion models, the Logistic model was the best in terms of estimation performance and statistical significance. The estimation results of the Generalized Logistic model confirm that investment in the telecommunication sector has a significant positive effect on market potential. The estimation of the Generalized Logistic model effectively describes the continuous growth of the Mongolian telecommunications market until recently. Conclusion: We have analyzed the diffusion pattern of the Mongolian telecommunications market and found that the amount of investment in the sector leads to the growth of the market size. This study is original in terms of its subject - Mongolian telecommunications market and methodology - time-varying market potential.

  • In this paper, we have proposed license plate recognition system for multi-national vehicle license plate using geometric features along with hybrid and seven segment pattern vectors. In the proposed system, we suggested to find horizontal and vertical relation after going through preparation process with inputted real-time license plate image of Korea and Japan, and then to classify license plate with using characteristic and geometric information of license plates. It classifies the extracted license plate images into letters and numbers, such as local name, local number, classification character and license consecutive numbers, and recognize license plate of Korea and Japan by applying hybrid and seven segments pattern vectors to classified letter and number region. License plate extraction step of the proposed system uses width and length information along with relative rate of Korean and Japanese license plate. Moreover, it exactly segmentation by letters with using each letter and number position information within license plate region, and recognizes Korean and Japanese license plates by applying hybrid and seven segment pattern vectors, containing characteristics related to letter size and movement within segmented letter area. As the result of testing the proposed system in real experiment, it recognized regardless of external lighting conditions as well as classifying license plates by nations, Korea and Japan. We have developed a system, recognizing regardless of inputted structural character of vehicle licenses and external environment.

  • Bioinformatics is formed with a blend of biology and informatics technologies and it employs the statistical methods and approaches for attending the concerning issues in the domains of nutrition, medical research and towards reviewing the living environment. The ceaseless growth of DNA sequencing technologies has resulted in the production of voluminous genomic data especially the DNA sequences thus calling out for increased storage and bandwidth. As of now, the bioinformatics confronts the major hurdle of management, interpretation and accurately preserving of this hefty information. Compression tends to be a beacon of hope towards resolving the aforementioned issues. Keeping the storage efficiently, a methodology has been recommended which for attending the same. In addition, there is introduction of a competent algorithm that aids in exact matching of small pattern. The DNA representation sequence is then implemented subsequently for determining 2 bases to 6 bases matching with the remaining input sequence. This process involves transforming of DNA sequence into an ASCII symbols in the first level and compress by using LZ77 compression method in the second level and after that form the grid variables with size 3 to hold the 100 characters. In the third level of compression, the compressed output is in the grid variables. Hence, the proposed algorithm S_Pattern DNA gives an average better compression ratio of 93% when compared to the existing compression algorithms for the datasets from the UCI repository.

  • Process conditions for generating nano patterns handle different process according to the pattern characteristics, and different process data according to patterns in questions. To efficiently find optimal process conditions for generating nano patterns, process data by experiment is needed consideration of the pattern characteristics concerning the equipment. In particular, coating methods of a cylindrical mold differ from it of a flat plate because of viscosity of coating materials. Also the coating thickness affects nano process and pattern line width. So coating method of coating thickness for cylindrical mold is very important on nano pattern generating. In this study, a method is proposed for coating Photo Resist through the spray in order to coat cylindrical mold and measuring the thickness of coating using measuring tip considering the size of cylindrical mold because there is no method in the existing SEM. The proposed method is applied to a real printed electronics system to verify its accuracy and efficiency.

  • This study was conducted to evaluate menu pattern and nutritional contents of snack menus provided by child care information centers in Seoul. Snack menus during March 2013 (morning snack : 125 cases, afternoon snack : 100 cases), including information on portion size, were collected from five child care information centers, after which the number of menu items, menu patterns, and nutritional contents were analyzed. About two-thirds of total snack menus included two menu items. There were significant differences in service time (morning & afternoon snacks). 'Beverage+Food' pattern (66.7%) was the most commonly used; 'Beverage' pattern was significantly higher in morning snacks (10.4%) than in afternoon snacks (1.0%). Morning and afternoon snacks provided 124.5 and 170.6 kcal of energy and 116.4 and 90.9 mg of calcium, respectively, which are 8.9% and 12.2% as well as 19.4%, and 15.2% of children's daily energy and calcium requirements. To improve the quality of food and nutrition offered to children through snacks at child carre centers, a more detailed snack menu plan as well as nutritional guidelines for institutions should be developed.

  • After COVID-19, the percentage of digital consumption has soared. Meanwhile, as the online platform market grows in size and digital commerce is activated, controversy over the "dark pattern" that induces consumers to do unintended things online continues. Dark patterns are deceptive design patterns that cause consumer rights and financial damage and can result in damaging fair market competition. As a result, the need to regulate dark patterns is raised not only by overseas regulators but also in Korea, and there are growing calls for strengthening consumer protection against dark patterns, with amendments to related laws being proposed by the National Assembly. On the other hand, there is no agreed definition of dark pattern from a normative point of view, and there is a concern that even legitimate advertising marketing activities of companies may be regulated, so a review of dark pattern regulatory measures is required. In this study, dark patterns were reviewed from a normative point of view and appropriate regulatory measures were analyzed. In particular, the problem of the dark pattern can be applied in a way that the market regulates and controls itself in consideration of the characteristics of the online platform. This study reviewed the possibility of self-regulation for dart patterns and proposed the role of each subject.

  • Chemical mechanical polishing(CMP) is essential technology to secure the depth of focus through the global planarization of wafer. But a variety of defects such as contamination, scratch, dishing, erosion and corrosion are occurred during CMP. Especially, dishing and erosion defects increase the resistance because they decrease the interconnect section area, and ultimately reduce the life time of the semiconductor. Due to this dishing and erosion must be prohibited. The pattern density and size in chip have a significant influence on dishing and erosion occurred over-polishing. Decreasing of abrasive concentration results in advanced pattern selectivity which can lead the uniform removal in chip and decrease of over-polishing. The fixed abrasive pad was applied and tested to reduce dishing and erosion in this paper. Consequently, reduced dishing and erosion was observed in CMP of tungsten pattern wafer with proposed fixed abrasive pad and chemicals.
