열가소성 섬유강화 복합재료를 위해 사출성형법이 사용되며, 사출품 내부의 섬유 배열이 열가소성 복합재료의 기계적 물성에 영향을 미친다. 본 연구에서는 탄소섬유/폴리프로필렌(CF/PP, carbon fiber/polypropylene) 복합재료를 사출성형할 때, 금형에 구리선을 붙여 사출품의 상태에 따라 확인되는 전기저항 변화도를 감지하여 사출품 내부의 섬유 배열 상태를 분석하였다. 사출될 때 발생되는 전기저항 변화도를 3가지의 종류로 구분할 수 있었다. 사출될 때 발생되는 금형의 전기저항 변화도 크기가 클수록 인장강도가 높은 CF/PP 성형품을 제조할 수 있었다. 이러한 이유는 CF/PP 성형품 내부의 섬유 배열에 의한 영향임을 접촉각 평가 및 시편의 표면 분석, 인장시편의 파단면 관찰 결과로 확인하였다. 균일한 섬유 배열을 가질 경우 사출 용융액 내부의 섬유가 열을 고르게 가지고 있으며, 금형에 일정한 열을 사출기간 동안 전달하게 되어 금형의 전기저항 변화도가 증가됨을 감지할 수 있었다. 궁극적으로 전기저항 평가방법을 이용하여 CF/PP 복합재료 성형품의 상태를 예측할 수 있었다.

인간이 자연의 식물과 교감하는 화예는 역사적인 배경과 민족성에 따라 특징을 가지며 인간의 영감과 조형 능력으로 서로 다른 양상의 문화가 탄생 되었다. 한국의 화예는 사계절기후의 자연 속에서 발생한, 문명의 소산으로 자연합일사상(自然合一思想)에서 출발하여 우리민족의 심성에 흐르고 있는 자연주의적 본질의 삶과 철학을 시대의 문화에 맞게 자연식물(草木)로서 그 여유로운 미를 덕(德), 지(志), 기(氣)로 배양되어 빚어내었다. 문인화(文人花)는 역사적 전통인 동양철학의 바탕에 계승되어온 정신 이념이 고격의 인품과 시정성{詩情性)을 바탕으로 "외양(外樣)"보다는 식물이 지닌 특성과 취향을 기교의 표출됨이 없이 철리(哲理)의 미학적 함축성을 빚어낸 조형예술이다 본 연구에서는 우리 정신문화의 화예 근간이 문인화(文人花)임을 규명하기 위하여 소나무(松)를 중심으로 문인화의 배경과 근원, 시정성, 상징성, 우의성, 그리고 문인화 작품에서 표현되는 화예의 조형성과, 화예 유전자 해독으로 미학적 특성을 파악함과 동시에 문헌의 기록을 도출하여 연대별로 정리 고찰하고, 한국화예의 정수(精髓)인 문인화론을 정립하고자 한다.

This study attempted to figure out the usage of the modular system in other fields through literature review and empirical study, analyze its structural method in fashion. After analyzing architecture & product-related books, the Internet data and previous studies, the modular system's five structural methods were obtained. Then, 991 photos of women's clothes from 2003 to 2014 were collected through the fashion websites in Korea and abroad. The results can be summarized as follows: First, the following five structures were derived: assembling structure, overlapping structure, arrangement structure, inserting structure and folding structure. Second, according to analysis on the structural method of the modular system in modern fashion, overlapping structure (34%) was the most common. Third, in fashion, the use of fastener for installation and removal is important for assembling structure. In terms of overlapping structure, 3D volume by vertical accumulation was commonly observed. Arrangement structure revealed a horizontal and flat shape through simple arrangement. In inserting structure, on the contrary, non-standardized modules were used as a part of clothes or decorative elements. In folding structure, origami technique for reduction and expansion was used.

Ship STEP(Standard for the Exchange of Product Model Data) which is composed of AP 215 (Ship Arrangement), AP 216(Ship Hull Form), AP 218 (Ship Structure), has been developed more than last 10 years and it is now at the stage just before IS(International Standard). It is expected that ship STEP would be used for the seamless data exchange among various CAD/CAM/CAE systems of shipbuilding process. In this paper the huge and complicated data structure of ship STEP is briefly reviewed at the level of ARM(Application Reference Model) and some abstract test cases which will be included as part of the standards are introduced. Basically ship STEP has common data model to be used without losing compatibility among those three different ship AP's, and it is defined as the modeling framework. Typical cases of data exchange during shipbuilding process, such as hull form data exchange between design office and model basin, midship structure data between shipbuilding yard and classification society are reviewed and STEP physical data are generated using commercial geometric modeling kernel. Test cases of ship arrangement at initial design stage and hydrodynamic data of crude oil carrier are also included.

We performed a study on the contaminant transfer in a clean space for the location of product and fan filter unit using computational fluid dynamics analysis. To simplify the real product moving process, three different non-moving cases regrading the locations of product were selected: no product, at the lower side, and at the upper and lower sides. And to investigate the characteristics of the contaminant transfer, the arrangement of fan filter units was varied. Local mean air-age and contaminant distribution were used as evaluation indices. From the results, the contaminant transfer to the product was the most when the products were simultaneously located at the upper and lower sides. And the contaminant was easily exhausted regardless of the location of product when the fan filter units were properly arranged at the top side of the clean space.

In that the Buddhism is the religion founded by Buddha, the settlement of Buddha's existence is very important in the temple building arrangement which symbolizes the Buddha's world. What symbolizes the Buddha in the temple are the pagoda and the Buddhist image. Among them, the Buddhist image is directly connected with the Golden Hall. This kind of double structure is settled as a typical pattern for the arrangement of buildings such as halls and pagodas. The earlier one between the pagoda and Buddhist image is the pagoda, of course. It can be inferred that, through the gradual expansion of the Buddhist images, the gravity was transferred from the pagoda to the Golden Hall. But, if the Buddhist image can be connected with the Golden Hall in that it was the product reflecting the requests on the Buddha and his teaching, the internal origin of the Buddhist image should also go back to the early Buddhism. In fact, the gravest building in Venuvana - vihara or Jetavana - anaehapindasyarama was the Golden Hall, the Buddha's residence. And in the summit of Grdhrakuta or Jetavana - anaehapindasyarama where Buddha stayed long, there is the gandha - kuti the Buddha's place till now. It means that the symbolic request on the Buddha and his teaching had existed even before the Buddhist image and that this tendency could be connected with the generation of Buddhist image. This paper is to show that the hall / pagoda structure generalized in the building arrangement of later age was originated not just from the Buddhist image and the sarira pagoda but from the gandha - kuti and the hair pagoda, and therefore the two should coexist inevitably. It is an attempt to develop a little more in the ideological perspective the general theory that the pagoda and the Buddhist image were fused into one precinct of temple later in their respective origins. That is, it tries to recognize the relation of pagoda and hall not as the conflicting one but as the complementary one.

In the initial stages of ship design, designers represent geometry, arrangement, and dimension of hull structures with 2D geometric primitives such as points, lines, arcs, and drawing symbols. However, these design information(‘2D geometric primitives’) defined in the drawing sheet require more intelligent translation processes by the designers in the next design stages. Thus, the loss of design semantics could be occurred and following design processes could be delayed. In the initial design stages, it is not easy to adopt commercial 3D CAD systems, which have been developed f3r being used in detail and production design stages, because the 3D CAD systems require detailed input for geometry definition. In this study, a semantic product model data structure was proposed, and an initial structural CAD system was developed based on the proposed data structure. Contents(‘product model data and design knowledges’) of the proposed data structure are filled with minimal input of the designers, and then 3D solid model and production material information can be automatically generated as occasion demands. Finally, the applicability of the proposed semantic product model data structure and the developed initial structural CAD system was verified through application to deadweight 300,000ton VLCC(Very Large Crude oil Carrier) product modeling procedure.

Despite the growing online exposure of retailes, offline retail channels still outperform online channels in the total retail volume of some countries. There is much interest in the physical layout plans of retail stores to expand sales. Product placement that have a large impact on customer purchasing behavior at offline retailers influences customer movement and sales volume. But in many cases, each retailer relies on unsystematic and autonomous product placement. When multiple products are sold with one purchase, the customer's movement for shopping may be evaluated in terms of customer efficiency and additional impulse purchase. In this paper, the social network is applied to sales data of a retail store and the result is used for evaluation of product placement and customer path. The frequent sales product composition was identified using k-core from sales data in the form of shopping baskets. The location was checked for the identified compositions of products, the spatial variance was measured and the customer's path was identified. With these results, the store arrangement of products was evaluated with appropriate improvement directions. The analysis method of this paper can be an alternative analysis approach for better layout of retail stores.

Temperature control of a rubber injection mold is important for the dimensional accuracy of product. The main objective of this paper is to optimize the arrangement of heaters by FEM and optimal design method. Firstly, 3-dimensional transient heat transfer analysis was carried out for a square specimen mold. Results of FE analysis are a good agreement with the experimental results, showing about 1.22~7.22% error in temperature distribution. Secondly, we suggested the optimal method about an arrangement of heaters of rubber injection mold by using the optimal design technique. Distances between heater's center and the contact surface of mold, distances between heater's center and symmetric surface were considered as design variables. And the variances between the temperatures of cavity surfaces and their average temperature were used as the objective functions. Applying the optimal solution, the temperature variation was improved about 52.9~88.1 % compared to the existing mold. As a result of sensitivity analysis for design variables, design variables parallel to the direction of the split plane in mold affect the largest on the surface temperature variation in mold cavity.
