통신업계의 사업자간 성과를 평가할 때 흔히 사용되는 지표가 ARPU(Average revenue per user) 이다. ARPU란 가입자당 수익으로 사업자의 총 수익을 가입자 수로 나누어 산출된다. 그러나 최근 통신 선진국 등지에서 ARPU적용의 문제점들을 제시하면서 새로운 지표인 AMPU(Average margin per user)를 사용하자는 주장이 일고 있다. AMPU란 가입자당 이익으로 사업자의 순이익을 가입자 수로 나누어 산출된 수치를 말한다. ARPU는 그 산정 메카니즘 상 변수인 수익과 가입자수에 대한 통일된 개념정립이 없으므로 사업자마다 각기 다른 회계처리를 할 수 있다. 특히 수익의 경우는 단말기 매출의 포함여부와 CP들에게 지불될 제3자수익에 대한 처리에 따라 수익수준이 달라지게 되며, 가입자수의 경우 가입자에 대한 정의가 명확하지 않기 때문에 실제 서비스를 이용하고 있지 않은 inactive가입자들의 포함여부에 따라 ARPU수치에 영향을 주게 된다. 따라서 사업자간 일률적이지 않은 회계처리에 따른 ARPU수치를 비교하는 것은 의미 없는 일이 될 수 있고 궁극적으로 이해 관계자들의 의사결정을 왜곡시킬 수 있는 요인이 된다. 따라서 수익과 비용을 모두 고려하는 개념인 AMPU의 사용은 ARPU로 인한 문제점을 해소시킬 수 있을 것이다. 따라서 보다 정확하고 비교가능한 정보를 제공하기 위해서는 통신산업의 사업자들과 이해관계자들이 AMPU지표의 공시에 협조해야 하며, 근본적으로 공시되는 수익이나 가입자수에 대한 개념의 정립이 시급할 것이다.

The purpose of this study is to develop machine embroidery textile designs for each technique that can be expressed using a single-headed computer embroidery sewing machine through a machine embroidery CAD system. For research, embroidery CAD utilized the Artistic digitizer, and the guillotine computer-mechanical magnetization machine used ELNA. The design concept was limited to portraits and relics of independence activists in six memorial halls built in Korea. The results of this study are as follows. First, it was found that the machine embroidery texture, which could only be produced by industries in the past, can be expand in the infinite creative embroidery design area by enabling the digitalization of motif images and the simulation of machine embroidery techniques through various layout options. Second, in the development of machine embroidery textures, it was found that the setting of the width, height, axis ratio, stitch, object, path, length, density, layer order, etc. in embroidery CAD is a very important part of determining the completeness of the embroidery results. Third, mechanical embroidery textile designs, which can be represented by single-head computer machine embroidery machine were able to show colorful embroidery results that differs from the original image by using seven main techniques and five deep technique alone or in combination, according to the designer's intention.

This study was aimed at determining the connection between ancient Korean embroidery and the Cheonsuguk mandala-embroidery insignia. Literature and empirical studies were conducted simultaneously, with the scope of these analyses spanning up to 7C in ancient Korea and Japan. The present study confirmed that the structure of Goguryeo tomb murals influenced by Buddhist art is represented in the Cheonsuguk mandala-embroidery insignia, and changes in the image resulted in modifications to the embroidery technique. Embroidery and color composition via complementary color contrast were implemented through Variant 1 outline stitching, which exhibited the development of Baekje embroidery. The embroidery technique confirmed that the form of embroidery developed in to chain stitching, needle looping stitching, outline stitching, satin stitching and Variant 1·2 outline stitching. These findings indicate that Cheonsuguk mandala-embroidery insignia is the result of the integration of the Goguryeo and Baekje cultures.

This study presents the results of conservation treatment and research on a folding screen with embroidered classical Chinese characters "壽" (su) for longevity and "福" (bok) for good fortune in various scripts. The project was conducted as part of the program for supporting overseas Korean galleries in 2016. The present mounting of this ten-panel folding screen was difficult to identify as it had previously been remounted in a modern style. However, clues to the original mounting were discovered during the conservation process. It was revealed that the folding screen was decorated with colors frequently used in Joseon-period, such as teal silk at the top and bottom of each panel and a violet frame. These features provided clues to the original mounting of the folding screen, of which only a few elements have survived. Since this study analyzes only case of one folding screen, further research is required to reveal the method of mounting folding screens applied during this same period.

In this paper, we investigated the aptness of embroidered textile dipole antenna as a wearable antenna. We designed an 2.45GHz ISM band embroidered textile dipole antenna on polyester textile. We investigated its characteristics depends on 3 variables, thickness of textile(ttextile), distance between textile and surface of body(gbody) and conductance of surface of body(𝜎body). Thickness of textile(ttextile) was affecting on the antenna resonance frequency(fo). As the conductance of surface of body(𝜎body) was increased the antenna resonance frequency(fo) and the antenna gain were increased slightly. The increment of the distance between textile and surface of body(gbody) caused relatively large increment of the antenna resonance frequency(fo) and the antenna gain. From the results, in the case of designing an embroidered textile dipole antenna as a wearable antenna we should consider carefully the two variables, distance between textile and surface of body(gbody) and thickness of textile(ttextile). Due to its large variation, the distance between textile and surface of body(gbody) may be a technical barrier in designing embroidered textile dipole antenna.

possessed by Dong-A University Museum is designated as Treasure No. 595, and has been known for a more exquisite, delicate and realistic expression and a colorful three-dimensional structure compared to the 'grass and insect painting' work and its value in art history. However, it has not been analyzed and studied in fabric craft despite it being an embroidered work. This study used scientific devices to examine and analyze the Screen's fabric, thread colors, and embroidery techniques to clarify its patterns and fabric craft characteristics for its value in the history of fabric craft. As a result, consists of eight sides and its subject matters and composition are similar to those of the general paintings of grass and insects. The patterns on each side of the 'grass and insect painting' include cucumber, cockscomb, day lily, balsam pear, gillyflower, watermelon, eggplant, and chrysanthemums from the first side. Among these flowers, the balsam pear is a special material not found in the existing paintings of grass and insect. The eighth side only has the chrysanthemums with no insects and reptiles, making it different from the typical forms of the paintings of grass and insect. The fabric of the Screen uses black that is not seen in other decorative embroideries to emphasize and maximize various colors of threads. The fabric used the weave structure of 5-end satin called Gong Dan [non-patterned satin]. The threads used extremely slightly twisted threads that are incidentally twisted. Some threads use one color, while other threads use two or mixed colors in combination for three-dimensional expressions. Because the threads are severely deterioration and faded, it is impossible to know the original colors, but the most frequently used colors are yellow to green and other colors remaining relatively prominently are blue, grown, and violet. The colors of day lily, gillyflower, and strawberries are currently remaining as reddish yellow, but it is anticipated that they were originally orange and red considering the existing paintings of grass and insects. The embroidery technique was mostly surface satin stitch to fill the surfaces. This shows the traditional women's wisdom to reduce the waste of color threads. Satin stitch is a relatively simple embroidery technique for decorating a surface, but it uses various color threads and divides the surfaces for combined vertical, horizontal, and diagonal stitches or for the combination of long and short stitches for various textures and the sense of volume. The bodies of insects use the combination of buttonhole stitch, outline stitch, and satin stitch for three-dimensional expressions, but the use of buttonhole stitch is particularly noticeable. In addition to that, decorative stitches were used to give volume to the leaves and surface pine needle stitches were done on the scouring rush to add more realistic texture. Decorative stitches were added on top of gillyflower, strawberries, and cucumbers for a more delicate touch. is valuable in the history of paintings and art and bears great importance in the history of Korean embroidery as it uses outstanding technique and colors of Korea to express the Shin Sa-im-dang's 'Grass and Insect Painting'.
