Lines of non-extension (LoNEs) on torso surface during arm abduction were investigated to provide appropriate location for inserting less-extensible yarns which can be used as seams for design and or clothing pressure variation. As experimental methods, reference points about 3 cm apart were marked on the skin and scanned at 30, $90^{\circ}$ and $135^{\circ}$ arm abduction. Skin deformation was measured by connecting reference points in horizontal, vertical and various angles of diagonal directions. Observation of skin deformation was made within the separated sections of the torso as well as integrated ones to cover the various occasions of design application. LoNEs of front and back torso were provided as mapping lines. Actual compression wear of three types was constructed with different pattern reduction rate at each separated section using LoNEs as boundary cutting lines. Clothing pressure and subjective evaluations of those three compression wear were evaluated by six subjects. LoNEs found in this study were useful as seam lines to differentiate clothing pressure at each part of the body, providing positive wear sensation. It is also expected that LoNEs can be paths for less strechable conductive yarns of IT-integrated upper garments.

In our previous studies (Chae et al., 1990; Chae et a1., 1993), we found that a phytochrome signal was clearly connected with the change in cytosolic free $Ca^{2+}$ concentration ($[Ca^{2+}]_i$) in oat cells. It was determined that the $[Ca^{2+}]_i$ change occured both by mobilization out of the intracellular $Ca^{2+}$ store and by influx from the medium. The specific aim of this work is to elucidate the processes connecting $Ca^{2+}$ mobilization and influx. The cells treated with thapsigargin (increasing $[Ca^{2+}]_i$ by inhibition of the $Ca^{2+}$-ATPase in the calcium pool) in the presence of external $Ca^{2+}$ showed the same increasing pattern (sustained increasing shape) of $[Ca^{2+}]_i$ as that measured in animal cells. Red light irradiation after thapsigargin treatment did not increase $[Ca^{2+}]_i$ These results suggest that thapsigargin also acts specifically in the processes of mobilization and influx of $Ca^{2+}$ in oat cells. When the cells were treated with TEA ($K^+$ channel blocker), changes in $[Ca^{2+}]_i$ were drastically reduced in comparison with that measured in the absence of TEA. The results suggest that the change in $[Ca^{2+}]_i$ due to red light irradiation is somehow related with $K^+$ channel opening to change membrane potential. The membrane potential change due to $K^+$ influx might be the critical factor in opening a voltage-dependent calcium channel for $Ca^{2+}$ influx.

The purpose of this study is to understand characteristic of expression in Korean style fashion design and investigated Korean style fashion design's deployment and design idea method as well as its esthetic value. The photographs for the research were selected from fashion collections during S/S 2003-F/W 2007 by four specialists in the department of textile and then analyzed with 288 final data. The results were as followings. First, the characteristics of design expression in Korean style fashion design were formation by separating partial shape from the whole, formation by shape's separation and repetition, and connecting formation by combination and transformation of parts. In the case of color, they were direct expression, contrasting formative expression, and gradual changing expression. In the case of pattern, they were the methods of filling, filling & emptying, and partial filling. Second, the deployments of Korean style fashion design were adding modern elements to traditional things, combining traditional elements and modern things, and adding traditional elements to modern things. The third, Korean style fashion design's idea methods were weaving, snatching, adding, and changing. Fourth, it was shown that esthetic values of Korean style fashion design were the interactive organism by building organic relationship, the optimum expressing beauty with minimum elements, the palpitation having dynamics and rhythmical beauty.

This study suggests the dynamic value chain model, that will be able to not only show changing processes to organization's significant capital by integrating an individual, implicit, and explicit knowledge which affect organizational decision making, but also distinguish the key driver for raising organizational competitive power because it makes possible to analyze sensitivity of performance along with decision making alternatives and policy changes from dynamic view by connecting knowledge management capability, knowledge management activity, and relations with organizational performance with specific strategic map. Recently, a lot of organizations show interest in measuring and evaluating their performance synthetically. In organizations taking knowledge management, they introduce effective value chain model like a dynamic balanced scorecard (DBSC), and therefore they can reflect their knowledge management condition as well as show their changes by checking performance of established vision and strategy periodically. Furthermore, they can ask for their inner members' understanding and participation by communicating with and inspiring their members with awareness that members are one of their group, present a base of benchmarking, and offer significant information for later decision making. The BSC has been a successful framework for measuring an organization's performance in various perspectives through translating an organization's vision and strategy into an interrelated set of key performance indicators and specific actions. The BSC, while having significant strengths over traditional performance measurement methods, however, has its own limitations, due to its static nature, such as overlooking two-way causation between performance indicators and neglecting the impact of delayed feedback flowing from the adoption of new strategies or policy changes. To overcome these limitations, this study employs SD, a methodology for understanding complex systems where dynamic feedback among the interrelated system components significantly impact on the system outcomes. The SD simulation model in the form of DBSC would serve as a useful strategic teaming tool for facilitating an organization's communication process through various scenario analyses as well as predicting the dynamic behavior pattern of their key performance measures over a future time frame. For the demonstration purpose, this study applied the DBSC model to Prototype of Korea manufacturing and service firm.

We analyzed the articles from "Kukje Shinmun" and "Busan Ilbo", which are two local newpapers of Busan Metropolitan City. The articles cover from January 1, 2013 to December 31, 2013. Meaningful pattern inherent in 2889 articles of which the title includes "Busan" and "Traffic" and related data was analyzed. Textmining method, which is a part of datamining, was used for the social network analysis (SNA). HDFS and MapReduce (from Hadoop ecosystem), which is open-source framework based on JAVA, were used with Linux environment (Uubntu-12.04LTS) for the construction of unstructured data and the storage, process and the analysis of big data. We implemented new algorithm that shows better visualization compared with the default one from R package, by providing the color and thickness based on the weight from each node and line connecting the nodes.

The wind load and structural characteristics of a twin building are more complex than those of conventional high-rise buildings. The pressure load due to wind on a twin building was therefore measured via wind tunnel experiments to analyze such characteristics. The wind pressure pattern was then deduced from measured data using proper orthogonal decomposition. Channeling and vortex shedding were observed in the first and second modes, respectively. The along-wind loads on the two buildings featured a positive correlation and the cross-wind loads featured no correlation. Such a correlation affected the wind-induced displacement. The structural member connecting the two buildings had an insignificant effect on the positive correlation, but it notably reduced the wind-induced displacement with a negative correlation.

In this study, a simulation-based damage estimation method for helidecks is proposed using an artificial neural network. The structural members that share a connecting node in the helideck are regarded as a damage group, and a total of 37,400 damage scenarios are numerically generated by applying randomly assigned damage to up to three damage groups. Modal analysis is then performed for all the damage scenarios, which are selectively used as either training or validation or verification sets based on the purpose of use. An artificial neural network with three hidden layers is constructed using a PyTorch program to recognize the patterns of the modal responses of the helideck model under both damaged and undamaged states, and the network is successively trained to minimize the loss function. Finally, the estimated damage rate from the proposed artificial neural network is compared to the actual assigned damage rate using 400 verification scenarios to show that the neural network is able to estimate the location and amount of structural damage precisely.

Red algal fertilization is unusual and offers a different model to the mechanism of intracellular transport of nuclei and polyspermy blocking. A female carpogonium (egg) undergoes plasmogamy with many spermatia (sperm) simultaneously at the receptive structure, trichogyne, which often contains numerous male nuclei. The pattern of selective transport of a male nucleus to the female nucleus, located in the cell body of the carpogonium, remain largely unknown. We tracked the movement of spermatial nuclei and cell organelles in the trichogyne after plasmogamy using time-lapse videography and fluorescent probes. The fertilization process of Bostrychia moritziana is composed of five distinctive stages: 1) gamete-gamete binding; 2) mitosis in the attached spermatia; 3) formation of a fertilization channel; 4) migration of spermatial nuclei into the trichogyne; and 5) cutting off of the trichogyne cytoplasm from the rest of the cell after karyogamy. Our results showed that actin microfilaments were involved in the above steps of fertilization, microtubules are involved only in spermatial mitosis. Time-lapse videography showed that the first ("primary") nucleus which entered to trichogyne moved quickly to the base of carpogonium and fused with the female nucleus. The transport of the primary male nucleus to the egg nucleus was complete before its second nucleus migrated into the trichogyne. Male nuclei from other spermatia stopped directional movement soon after the first one entered the carpogonial base and oscillated near where they entered trichogyne. The cytoplasm of the trichogyne was cut off at a narrow neck connecting the trichogyne and carpogonial base after gamete nuclear fusion but gamete binding and plasmogamy continued on the trichogyne. Spermatial organelles, including mitochondria, entered the trichogyne together with the nuclei but did not show any directional movement and remained close to where they entered. These results suggest that polyspermy blocking in B. moritziana is achieved by the selective and rapid transport of the first nucleus entered trichogyne and the rupture of the trichogyne after gamete karyogamy.

Purpose: This study was performed to verify reliability and validity of Korean Patient Classification System for nurses(KPCS-1), to estimate nursing time conversion index, and to classify patients into groups according to KPCS-1 scores. Methods: KPCS-1 was revised from KPCS by a professional review team. Interrater reliability and construct validity of KPCS-1 were verified by data from 433 patients. Direct and indirect nursing time of 204 patients were measured by stopwatch observation and self reports for 24 hours. Nursing time conversion index was calculated. Results: KPCS-1 consisted of 12 area, 50 nursing activities, and 73 items. The interrater reliability was tested between two nurse group (r=.88, p<.001) and construct validity was verified according to medical department (F=10.97, p<.001) and patient pattern (F=5.54, p=.001). The correlation of nursing time and classification score was also statistically significant (r=.56, p<.001). The nursing time conversion index was 9.03 minutes per 1 classification score. The patients were classified into 4 groups by the classification scores. Conclusion: KPCS-1 can be a useful factor type patient classification system for general ward. Further study is needed to evaluate validity and reliability for refining KPCS-1 and to develop ways connecting the scores with nursing outcomes.

This study aims to use Art brut works-the artwork of the socially underprivileged and alienated-to influence social roles in fashion design, employing a formative expression method to promote social acceptance of diversity in the industry. The research method involved investigating Art brut's concept and evolution in domestic and foreign literature and previous studies. The formative characteristics of the movement were derived by analyzing the works of Art brut artist Johann Hauser. One hundred and twenty images of Johann's work were collected through online sources like the Gugging Museum's website, Christian Berst Gallery's website were developed as fashion design using the CLO 3D program. The formative characteristics of Johann's works appeared to be transparent overlapping, divisional decorativeness emphasized simplicity, and vibrant chromaticity. Based on this analysis, the results of the 3D digital fashion designs were as follows. First, the characteristics of the atypical objects and figures in Johann's works were applied to the design silhouette, revealing a uniquely beautiful form. Second, Johann used a method in which numerous line shapes overlap and fill the area. The point of connecting the work is expressed as a graphic pattern by decorating the lines of the hem and hem of the garment with piping or attaching overlapping straps on top of pants and dresses. Third, the combination of overlapping colors used in Johann's work is a color block design of fashion, which utilizes the formative fun.
