The advanced semiconductor technology and electronic design automation(EDA) tools make it possible to implement the system on the programmable logic devices. The electronic design method is also changing from schematic capture to hardware description language. In this paper, I present the architecture of multi-dimensional digital filter which can be efficiently implemented on PLDs. This is based on the former research results which are called algorithm decomposition technique. Algorithm decomposition technique is used to obtain the computational primitive from the state space equations of the multi-dimensional digital filtering algorithm. The obtained computational primitive is designed with VHDL. This can be used to implement the filtering system as a component. The designed filtering system is implemented on the PLD. Therefore, the filter can be upgradable on system. It is greatly reduced the time-to-market time of the system that is based on the multi-dimensional filter.

The reason that we are familiar with fashion from the 1950s is because of the work such as New Look done by a french fashion designer, Christian Dior who had taken on an almost mythical significance by his name. Moreover, in the sense of popularity, the appearance of Marilyn Monroe and Audrey Hepburn, two typical Hollywood actresses who each has directly-opposed image, is the symbol of youthful America of the 1950s and represents the remarkable start of the American fashion. Still, these days designers and mass medias recall the fashion from the 50s remaking and parodying it to suit public's taste. Being due to the World War II, Europe suffered not only the loss of its national tradition and reputation but also got a fatal blow politically and economically. On the other hand, the United States of America occupied a primary position in the world and outstandingly became the most powerful country. The American fashion of the 1950s represents youth and newness and rejects outdated and outmoded style. In this period, appears the indication which announces previously the youth culture. Poodle skirt is the fashion item that acquired popularity among young american women and girls in the late 1950s. In effect, it is the fashion as American as apple pie. A costly A-line skirt had been transformed into a cheap felt skirt. Instead of a real poodle dog which was carried by French women like an accessory, they embroidered a poodle dog on the lower edge of their skirt. As deriding the snobbish gait, they swayed themselves frantically to the rhythm of Rock n' Roll which swept those days. This was an attitude of young Americans against the existing trend of Europe. Poodle skirt showed the free spirit and intention of young people unbound to custom and established vogue. In addition, in the aspect of comprising the American spirit of independent, pioneer, and subjective American people, it goes beyond the bounds of common concept of fad. Poodle skirt is an unique symbol of the 1950s' American fashion which prognosticates the advent of the United States and the success in modern fashion world which was changing after 1950s.
This study examined a phenomenon of exaggerated hairstyle in the history of Western custom through publications related with Western costume and research papers. By adopting the criteria of Delong, M. R. to analyze visual forms shown by interaction between human body and costume worn over the body, it analyzed the formative characteristics by the interaction between hairstyle and costume. In addition, it inferred the aesthetic characteristics through content analysis of examined phenomenon focusing on socio-cultural background and costume socio-psychological precedent studies. Formative characteristics of exaggerated hairstyle applied by analysis criteria of Delong, M. R. were in pursuit of the emphasis style. This was clearly and intensively recognized by forming spaces for mostly closure style, part style, three dimensional style, determinate style, and space separation style. Regarding the interaction between hair and ornamentations, 'precedence of ornamentation' was pursued as ornamentations were recognized earlier than the hair itself. It means associative meanings of the surface effect were accompanied by emotions of 'intensiveness' and the pursuit of the attractive style. As for the interaction between hairstyle and costume, there were many cases of pursuing 'continuity' mutually and visually by connecting the hairstyle and the costume. Aesthetic characteristics of exaggerated hairstyle were inferred as 1) the expression of the sprite of the age(i.e. art, culture, politics, society, ideology, religion), 2) symbols of wealth, class, authority, and excellence, 3) pursuit of addicted desire to ornament, and 4) harmony through continuity with costume. This study verified that hairstyle was connected as a part of costume, or formed as a way to express deeper human psychology beyond just a part of a costume. It was also confirmed that hairstyle was an expressive method to express the spirit of the age, such as art, culture, society, religion, ideology.
PURPOSE. Cement-retained implant prostheses can lack proper retrievability during repair, and residual cement can cause peri-implantitis. The purpose of this in vitro study was to evaluate the influence of abutment height and convergence angle on the retrievability of cement-retained implant prostheses with lingual slots, known as retrievable cement-type slots (RCS). MATERIALS AND METHODS. We fabricated six types of titanium abutments (10 of each type) with two different heights (4 mm and 6 mm), three different convergence angles ($8^{\circ}$, $10^{\circ}$, and $12^{\circ}$), a sloped shoulder margin (0.6 mm depth), a rectangular shape ($6mm{\times}6.5mm$) with rounded edges, and a rectangular ledge ($2mm{\times}1mm$) for the RCS. One monolithic zirconia crown was fabricated for each abutment using a dental computer-aided design/computer-aided manufacturing system. The abutments and crowns were permanently cemented together with dual-curing resin cement, followed by 24 hours in demineralized water at room temperature. Using a custom-made device with a slot driver and torque gauge, we recorded the torque ($N{\cdot}cm$) required to remove the crowns. Statistical analysis was conducted using multiple regression analysis and Mann-Whitney U tests (${\alpha}=.05$). RESULTS. Removal torques significantly decreased as convergence angles increased. Multiple regression analysis showed no significant interaction between the abutment height and the convergence angle (Durbin-Watson ratio: 2.186). CONCLUSION. Within the limitations of this in vitro study, we suggest that the retrievability of cement-retained implant prostheses with RCS can be maintained by adjusting the abutment height and convergence angle, even when they are permanently cemented together.
The spatial separation of male's and female's area due to the law of 'Naeoei' is one of the trademark features of residence by the building principle of 'Confucianism' in the upper class house in the late of the Chosun Dynasty. Thanks to modernized agriculture and commerce, the residence of 'Sinheung-Yangban' developed. And they were influenced by the economic and living characteristics than traditional custom. So the residence of 'Sinheung-Yangban' is very important in terms of the course of modernizing of the korean traditional residence. Researcher figures out the influences of the law of 'Naeoei' in residence and the characteristics of male's and female's field in terms of daily life with investigating the residence of 'Sinheung-Yangban' as the upper class house in the late of the Chosun Dynasty. Through this, the goal of this study is to find the properties of male's and female's field of upper class houses in the late of the Chosun Dynasty. With this study, the followings are the characteristics of male's and female's spatial composition of upper class houses in Gyong-gi Province in the late of the Chosun Dynasty. First, the traditional law of 'Naeoei' plays a primary role as the principle of building of upper class houses in Gyong-gi Province in the late of the Chosun Dynasty. With a natural result, there is a clear spatial separation as the male's and female's social role. Second, 'An-Chae' and 'Sarang-Chae' as male's and female's living space are separated physically, but real living life tends to be syntagmatically made with 'An-Madang' as the center. Third, spatial integration of 'An-Madang' as the center results in the development of architectural connection factors of 'An-Chae' and 'BaKat-Chae' adjoining 'An-Madang', facing 'Toei-Gan', 'Maru', and 'door'. Forth, the boundary of male's and female's areas is relatively clear between dwellers and visitors, but on the other hand, the separation of male's and female's spaces between family members has little significance.

The value that evaluates ancient Oriental civilization and culture is Hwa-i-kwan(華夷觀: the view that China is only good country and the others are savages) as Confucianism. Generally, Hwa-i-kwan(華夷觀) includes cultural Hwa-i-kwan(華夷觀) as Confucian culture is only superior, Han-centered racial Hwa-i-kwan(華夷觀), and country-centered geographical Hwa-i-kwan(華夷觀). As times goes on, instead racial and geographical Hwa-i-kwan(華夷觀) is diluted, cultural Hwa-i-kwan(華夷觀) was just emphasized. The value of cutural Hwa-i-kwan(華夷觀) is presented on dressing system and hair style becoming an issue in Confucian culture. This study intends to research how Hwa-i-ron in latter period of Chosun influenced the view of Ching men's hair style, pigtail. For this study, 5 books of Yeon-hang-rok in $17{\sim}18$ centuries are chosen, but some parts of them would be selected concerning with hairdressing and would be studied with other documents. Hwa-i-kwan(華夷觀) had dominated in the latter period of Chosun and had been making proprieties, then geographical and racial Hwa-i-kwan(華夷觀) were disappeared when Ching had been building a big cultural country, but cultural Hwa-i-kwan(華夷觀) had been stronger in latter period of Chosun than before, it had been a standard in all proprieties. After all, not only did cultural Hwa-i-kwan(華夷觀) become a standard of all proprieties in Chosun, but it was applied to the view of Ching men's hairstyle. So, people thought that pigtail, Ching men's hairstyle, is a custom of the savages. out of Chinese proprieties. Therefore, this cultural Hwa-i-kwan(華夷觀) that Chosun is a real China through taking over Chinese proprieties might be in that age.

The purpose of this research is to compare the people’s attitude toward 3-D body scanning by their gender and age in order to provide the application of 3-D body scanning data for new services or products. This study collected questionnaire data from 442 Korean females and 258 Korean males who participated in the 3-D body scanning. The result of this study were as follows: 1. Most people had good feelings for 3-D body scanning. Male respondents were more dissatisfied than female, and teenagers had higher dissatisfaction rate than other age groups for the measurement garment. 2. 80.5% of all respondents had the intention for re-measurement of 3-D body scanning. Male respondents and teenagers had low intention for re-measurement. 3. For the use of 3-D body scanning data, 79.6% said "yes" for making avatar, and 88.3% agreed with the custom made clothes. There was no difference between gender and age for this question. The results of the study will demonstrate how clothing retailers and marketers can use the 3-D body scanning data.
In this paper, we propose the design and implementation of a portable, extensible, and efficient performance visualization framework for high performance parallel program development. The framework adopts a layered architecture:consists of three independent layers instrumentation layer, trace interface layer and visualization layer. The instrumentation layer was constructed as an ECL which captures generated events, and the EDL/JPAL constitutes the trace interface layer to provide problem-oriented interfaces between visualization layer and instrumentation layer. Finally, the visualization layer was designed as plug-and-play style for easy elimination, addition and composition of various filters, views and view groups, The proposed performance visualization framework is expected to be used as an independent performance debugging and analysis tool and as a core component in an integrated parallel programming environment.
The consumption of pre-treated vegetables (including fresh-cut vegetables) that are washed, peeled, and trimmed has been significantly increased because of their easy use for cooking. Vegetable cutting machines have been widely utilized for producing fresh-cut vegetables or agricultural products of different sizes; however, the design standard is not established for specific types of agricultural products. Therefore, this study was conducted to determine mechanical properties (compressive and shear forces) of targeted agricultural products (radish, carrot, squash, cucumber, shiitake mushroom, and sweet potato) for developing a multipurpose vegetable cutting machine. According to ASAE standard (s368.3), compressive and shear forces of targeted agricultural products were measured by using a custom built UTM (universal testing machine). Shape type of samples and speed ranges (5 - 15 mm/min) of loading rate on bioyield and shear points varied depending on the targeted agricultural product. The range of averaged bioyield points of targeted agricultural products were between 7.89 and 146.98 N. On the other hand, their averaged shear points ranged from 22.50 to 53.47 N. Results clearly showed that the bioyield and shear points of targeted agricultural products were thoroughly affected by their components. As measuring compressive and shear forces of a variety of agricultural products, it will be feasible to calculate blade cutting force for designing multipurpose vegetable cutting machine.
Along with the development of information and communication technology, smart education that can learn without restrictions of time, place and equipment is activated even in the field of education. Although smart education is provided with content-based training solutions, construction of a system that grasps individual characteristics of learners and provides personalized learning is relatively weak. The activity of free choice is an important play activity of early childhood education, but it is not implemented efficiently by relying on the clinical observation of the teacher. If the IoT(Internet of Things) technology based on Hyper-Connected is applied to free-choice activities, it is possible to provide the child's personalized activity type and play-form analysis based on objective and stylized data. In this paper, we design and implement a system to monitor the child's activity of free choice by building an IoT environment that is based on open source hardware. The proposed system provides children's activity information as objective data and will be used as teacher's work mitigation and custom training material for each child.
