무선 메쉬 네트워크는 네트워크 구성의 용이성과 비용적인 장점으로 각광받고 있는 무선 백본 네트워크 기술이다. 최근 상용화된 제품이 출시되고 있지만, 대부분의 기존 연구 기술은 시뮬레이션을 통해 성능을 분석하였다. 본 논문에서는 실제 상황을 고려하여 무선 메쉬 네트워크 테스트베드를 구축하였다. 본 테스트 베드는 무선 분산 시스템(Wireless Distribution System)과 브릿지를 응용하여 멀티채널 멀티 인터페이스와 동적인 위치기반 라우팅 프로토콜을 지원한다. 위치기반 라우팅 프로토콜은 링크 채널 변화와 물리적 거리를 고려한 메트릭을 이용하여 무선 간섭에 강하게 설계하였다. 그리고 메쉬 클라이언트들은 중앙 집중 주소 관리 서버를 통해 주소를 할당 받아 통신하며, 간이 망 네트워크 관리 프로토콜을 통해 망을 관리하도록 설계 및 구현하였다. Wireless Mesh Network(WMN) is wireless backbone networks technique which has ease of network configuration and cost of advantage. Recently, WNM released a new product, but most of existing research and technology analysis the performance through the simulation. This paper build the wireless mesh network testbed for actual situation. Testbed supports multi-channel multi-interface using bridge, the Wireless Distribution System and dynamic location-based routing protocol. This routing protocol strongly design against wireless interference using metric for link channel change and real distance. Then, the address of mesh clients assigned by the centralized address management server. Mesh clients is designed and implemented to manage network through Simple Network Management Protocol.

This study was intended to analyze conventional grading increments and methods for middle-age men`s pants, and to suggest new grading guidelines that will enable to improve satisfaction with size and silhouette as a result of combining the concept of grading, which help maintain the ratio and proportion by sizes as one of ready-made apparel`s advantages, with body form oriented and aesthetic approaches. In the apparel industry the current sizing specifications and methods adopted by relevant companies, as well as the characteristics of body forms of men aged 35 to 55 years were comparatively analyzed to find out problems and ultimately to suggest their solutions or improvements. It was considered that as the conventional grading practices used in the industry were customary on the basis of the past experiences, it was required to take the body forms of target consumers into account and also, to reconsider the conventional grading methods. Analyses of sizing and specifications by brands show that 4 to 19 sizes including 82 or 84 as standard size have been produced. Since men`s apparel has a large number of sizes with the large range of sizes, grading is critically important. As silhouettes depend on the distribution of grading rule values at each point of increment pattern in the main regions during grading, it is necessary to consider both size grading and form variations. To maintain an appropriate silhouette with keeping the angle of center back line of a pattern, it is desirable to set the ratio of side line part to center part from the crease line to approximately 3:7. It is required to diversify the values of grading rules according to different sizes and pattern regions in consideration for the body forms of key consumers. In addition, if the natural lines of designs and patterns for the width increments of waist circumference and hip circumference, the increments of hip width in pant`s front and back panels, the ratio of grading rule values of the right and left sides of crease line, knee circumference, thigh circumference and so on are taken into account, grading will be satisfactory in the all aspects of size, silhouette and ratio.

The purpose of this study is to analyze the technical pattern and product characteristics of outdoor sportswear marketed in Northern Europe and North America. Based on the results of this study, we wanted to provide practical data on the characteristics of products with high functionality and fashionability for developing outdoor sportswear. Therefore, in this study, technical pattern, textiles, details, sewing, compatibility with wearable devices, and certification of 33 marketed outdoor sportswear were analyzed. After analyzing various technical patterns, the bent arm pattern using two-piece panel and a raised arm pattern connecting the side seam with the inner seam of the sleeve appeared on the top. Additionally, the patterns of bent legs with darts in the knee, cutting the posterior, and inserting the gusset in the crotch were mainly seen in the bottoms. By analyzing product characteristics, ergonomic pattern design for easy activity and functional materials was used for climate adaptation in extreme outdoor wear. On the other hand, for outdoor wear meant for trekking or hiking, details, such as portability and easy storage, were considered. Eco-friendly materials were used while ensuring light weight and comfort. Furthermore, for convenience of life, safety, and health, wearable devices were integrated into the outdoor sportswear. Eco-friendly green certification of outdoor products was obtained for the labor environment and production process, and relevant information was provided to consumers.

어유장의 휘발성 향기 성분들을 용매추출을 이용하여 분리, 농축하였으며, GC-MS로 분석하였다. 총 36가지의 휘발성 성분들이 검출되었으며, 11개의 aliphatic hydrocarbons, 4개의 acids, 2개의 ketones, 5개의 phenols, 7개의 alcohols, 1개의 pyrazines, 4개의 pyrones와 furanones, 2개의 miscellaneous components 등으로 구성되어 있었다. 특히, acids인 butanoic acid가 높은 함량을 나타내었다. 어육장의 향기활성 성분을 규명하기 위해 용매추출을 이용하여 휘발성 성분들을 분리 후 향추출물 희석분석법으로 flavor dilution(FD) factor(Log₃ FD)를 구하였다. 이 결과 어육장에서 총 20종의 향기활성 성분들이 확인되었다. 이 중 군덕내의 특성을 지닌 butanoic acid와 구운 감자향을 지닌 methional이 높은 FD factor를 보였으며, 이들 성분 외에 높은(Log₃ FD>7)를 나타내는 성분들로는 2-methyl-2-butanol(soysauce-like), 3-hydroxy-2-butanone(buttery), 2-furanmethanol(burnt sugar-like) 등이 있었다. 본 실험에서는 어육장용 시료로 하여 휘발성 향기성분 및 향기활성 성분들을 GC-MS 및 AEDA법에 의해 분석함으로 어육장 특유의 향미특성을 규명하였다. 이는 앞으로 고급화된 장류 제품으로서는 물론, 다양한 식품에서 조미소재로의 어육장의 활용도를 높이는데 기여할 것이다. The volatile components in Eoyuk-jang, a traditional Korean fermented food, were isolated using solvent extraction, and analyzed by gas chromatography-mass spectrometry (GC-MS). A total of 36 components, including 11 aliphatic hydrocarbons, 4 acids, 2 ketones, 5 phenols, 7 alcohols, 1 pyrazines, 4 pyrones and furanones, and 2 miscellaneous components, were found in Eoyuk-jang; among them, butanoic acid was quantitatively dominant. In addition, the aroma-active compounds were determined by gas chromatography-olfactometry (GC-O) using aroma extract dilution analysis (AEDA). A total of 20 aroma-active compounds were detected by GC-O. Butanoic acid (rancid) and methional (cooked potato-like) were the most potent aroma-active compounds with the highest FD factors (Log₃ FD), followed by 2-methyl-2-butanol (soysauce-like), 3-hydroxy-2-butanone (buttery), and 2-furanmethanol (burnt sugar-like).

This study develops pant patterns using body shape, measurement and shell mesh data to decide optimal women``s pants according to styles with excellent size, fit and shape for different individuals and silhouettes. Standard landmarks, lines, triangles and structures were set on a 3D scanned lower body shell to represent women in their twenties and flattened as a 2D pattern. Patterns were created and analyzed according to culotte, formal, slacks and tight type considering crotch shape, location of the crotch point, and adjusting waist darts. Flattened patterns were rotated to compare existing methods. The crease lines were then set through the hip protrusion point and compared. The main factor of the pant pattern were extracted, total rise, crotch depth, crotch width, angle of center line, shape of the center line curve, the thigh width, the amount of waist dart, and crease line position. With going tight style from the culotte, the fits are closer to the figure with minimized thigh circumference, the dart amount decreases, the crotch depth increases, the crotch extensions were shorter, and the angle of the center back increased. The total rise is U shape for culotte and is closer to V shape as the silhouette tightens. T-test of appearance evaluation of the developed pant pattern were conducted after analyzing measurements and shapes of each styles. The results of the developed patterns were superior to existing patterns in accordance to hip line between body and pants as well as appearance evaluation. We found systematic mechanisms among pattern factors that create various pant silhouettes. Evidence on classification of the silhouettes of traditional types of pants were explained objectively through the process of playing out 3D forms.
