  • 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.

  • Flow pulsation in the gap connecting with two parallel channels is investigated by RANS and URANS approaches. The two parallel channels are connected by a small channel called for a gap. The parallel channels are designed to have different cross section area with its ratio of 0.5. Computations are conducted using a CFX 11.0 code. The bulk Reynolds number is 60,000. Predicted results are compared with the previous experimental data. Mean velocity profile at the center of gap region are compared with experiments for its validation. Spectral analysis on the lateral velocity in the center of the gap was performed. Auto correlation for the axial-flow velocity pattern was presented. The unsteady structure of the flow pulsation was visualized in the region of the gap in the parallel channel.

  • The appearance of new machine tools with higher flexibility is in need of a basic structure design system for establishing the systematic and rationalized design and manufacturing procedures. In this study. the basic structure design system for machine tools is realized based on the modular construction method. Machine tools are represented as a whole and modular complex with the directed graph, and all possible structural configurations and codes of machine tools for satisfying the machining requirement are derived from the DNA data and connecting patterns of basic structural elements. Especially the structural configurations of machine tools are visualized by the solid modeling techniques and 3-D graphics techniques.

  • This paper proposes a new test pattern generation methodology for combinational logic circuits using neural networks based on a modular structure. The CUT (Circuit Under Test) is described in our gate level hardware description language. By conferring neural database, the CUT is compiled to an ATPG (Automatic Test Pattern Generation) neural network. Each logic gate in CUT is represented as a discrete Hopfield network. Such a neual network is called a gate module in this paper. All the gate modules for a CUT form an ATPG neural network by connecting each module through message passing paths by which the states of modules are transferred to their adjacent modules. A fault is injected by setting the activation values of some neurons at given values and by invalidating connections between some gate modules. A test pattern for an injected fault is obtained when all gate modules in the ATPG neural network are stabilized through evolution and mutual interactions. The proposed methodology is efficient for test generation, known to be NP-complete, through its massive paralelism. Some results on combinational logic circuits confirm the feasibility of the proposed methodology.

  • With the advent of high-resolution high-sensitivity observations, spiral patterns have been revealed around several asymptotic giant branch (AGB) stars. Such patterns can provide possible evidence for the existence of central binary stars embedded in outflowing circumstellar envelopes. It is, however, not generally recognized that the binary induced pattern, vertically extended from the orbital plane, exhibits a ring-like pattern with an inclined viewing angle. I will first review the binary-induced spiral-shell patterns on the AGB circumstellar envelopes with the effect of inclination angle with respect to the orbital plane, of which large inclination cases reveal incomplete ring-like patterns. I will describe a method of extracting such spiral-shell from the gas kinematics of an incomplete ring-like pattern to place constraints on the characteristics of the (unknown) central binary stars. This first success may open the possibility of connecting the ring-like patterns commonly found in the AGB circumstellar envelopes and in the outer parts of (pre-)planetary nebulae and pointing to the conceivable presence of central binary systems, which may give a clue for the onset of asymmetrical planetary nebulae.

  • This paper presents a novel method for simultaneously and automatically choosing the nonlinear structures of regressors or discriminant functions, as well as the number of terms to include in a rule-based regression model or pattern classifier. Variables are first partitioned into subsets each of which has a linguistic term (called a causal condition) associated with it; fuzzy sets are used to model the terms. Candidate interconnections (causal combinations) of either a term or its complement are formed, where the connecting word is AND which is modeled using the minimum operation. The data establishes which of the candidate causal combinations survive. A novel theoretical result leads to an exponential speedup in establishing this.

  • Objective : The purpose of this study is to explore the therapeutic potential of Shanghanlun for neuropsychiatric disorders through a comparative review of five neuropsychiatric disorder cases diagnosed with Greater yin disease pattern/syndrome (太陰病). Methods : We collected and compared five neuropsychiatric cases diagnosed and treated with Greater yin disease pattern/syndrome (太陰病) from four korean medicine clinics. Clinical symptoms common to the five cases were analyzed by connecting them with Shanghanlun provision 273 and 279. Results : In all five cases, the improvement of chief complaints and decrease in general anxiety were observed after administration of Gyejigajakyak-tang (桂枝加芍薬湯) and Gyejigadaehwang-tang (圭支加大黃湯). In addition, neuropsychiatric symptoms and physical symptoms that are mentioned in Shanghanlun provision 273 and 279 were confirmed in all five cases. Conclusions : We not only reconfirmed that the core features of Greater yin disease pattern/syndrome(太陰病) proposed in previous studies; zi-tong (自痛), yin-er (因爾), jie-ying (結硬), but also that the physical symptoms associated with fu-man (腹満), tu (吐) and zi-li (自利) were common in the presenting symptoms and past histories of the five patients.

  • The KTX, first Korean Highspeed train from Seoul to Busan, is scheduled to begin its passenger service in 2004, with improvement of existing railroad between Daegu and Busan and Honam region. This paper aims to suggest the best train operation plan and detailed diagram pattern so that the KTX could work effectively as much as possible. I suggest for instance, connecting direct train and local train, hub stations plan, multi-destination train, and improvement of fare system.

  • 현대산업의 주 구성요소인 컴퓨터 자동화는 섬유디자인 분야에 커다란 변화를 가져왔다. 패턴을 디자인할 때 수작업에만 의존해 왔던 디자이너들은 디자인과 색채의 다양성과 제작시간의 단축하기 위해 CAD를 디자인 도구로 하여 패턴을 창조하고 그것을 구매자에게 프리젠테이션하는 등 컴퓨터 활용이 보편화되고 있다. 당초무늬는 어느 특정식물을 소재로 패턴화 시킨 것이 아니라 이집트에서 발견된 인동문을 모체로 하여 발전된 공상적인 식물덩굴무늬로서 세계적인 무늬이다. 당초무늬는 줄기를 기준으로 꽃이나 잎이 서로 얽히어 연결됨으로서 아름답고 유연한 선을 나타내고 있으며 이 같은 선은 단순하면서도 장식적인 요소가 잘 표현되어 있다. 한국에서 당초문양은 장수와 다남을 상징하는 상서로운 문양이기 때문에 예로부터 우리 조상들이 즐겨 사용했으며 생활 속에 깊숙이 자리잡고 있다. 본 연구는 당초문양을 패턴의 모티브로 하여 CAD를 이용하여 패턴 디자인함으로써 디자인 개발의 다양성을 제시하였다.
