  • 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.

  • 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.

  • Computer automation, developed into a major element of modern industry, has also brought to great change in textile design field. Traditional textile designers have been created patterns by free hand drawing with brush. The modern textile designers create and present, on the other hand, printed or woven designs much more utilizing extensively the computer cad as design tool, creating various designs and colors as well as reducing the creative process. Vine pattern the worldwide known is not a pattern simplified from a specific plant but it is rather a plant imaginative pattern that has been developed from a winter plant found in ancient Egypt. Vine patterns express gorgeous curve lines, which are simple but decorative by connecting flowers or leaves with stems. These vine patterns have also been widely used for their decorative arts in Korea since early times because they were believe to a favorable auspice pattern symbolizing a long-life and fertility. In this study, the possibility of developing various designs is explored and presented by utilizing the motif of vine pattern in CAD program.
