This study analyzes the innovation process of the value chain in the fashion industry. It examines the differences between traditional and FF-based methods that include value chain processes such as design, production, and distribution-sales process. In the literature review and case studies, general propositions were drawn from each innovative stage by a comparison analysis. First, design speed is the main factor to explain the impact of IT in the design process. Second, small quantity batch production becomes main stream by the adoption of a computer-integrated manufacturing system in the production process. Third, cost reduction and speedup improvement are results of innovation in the distribution process. Last, a customized interface provides important information that can integrate the value chain and make useful customer relationships in the sales process. Fast fashion is the best product of these procedural innovations in the overall value chain. Consequently, this study confirmed that the general propositions referred above were acceptable and adaptable in the case of ZARA in terms of fast fashion strategy.

Teacher's gaze empathy for students in science class is considered to be effective in enhancing the learning effect. Thus, studies on gaze empathy have been conducted, but most of the studies are just to reveal the characteristics of gaze. Therefore, it is necessary to deal with a research to raise the level of science teacher's gaze empathy. The purpose of this study is to develop an instruction consulting strategy based on eye tracking for improving science teachers' gaze empathy. In this study, we selected and analyzed relevant literature on teacher's gaze empathy. We also designed a consulting strategy and then revised the design through expert reviews on validity and reliability. The developed consulting strategy was aimed to improve science teacher's gaze empathy and set quantitative goal based on eye tracking. The consulting strategy consisted of six steps: preparation for consulting, measurement and analysis of teacher's gaze empathy, instruction and feedback of gaze empathy, training for improving gaze empathy, evaluation of consulting result, and completion of the consulting. In addition, the consultation was completed or repeated again through the measurement and evaluation of gaze empathy using eye tracking. The developed consulting strategy has a value in that it provides an alternative with quantitative diagnosis and prescription for improving gaze empathy. The strategy can contribute to enhance teacher professional competency through the analysis of teaching behavior.

This study was performed to analyze of market segmentation of outpatient services on the based of consumption values. Self-reported questionnaires of six hospital outpatients 600 were analyzed by six consumption values categories: functional values, social values, emotional value, rarity value, situational values, health related values. The main results of this research is as following; 1. The consumption values were significantly different in that sociodemographic characteristics. Especially, the more older aged group, farmer and married people, the more they preferred to functional value, social value, emotional value and rarity value than younger aged group and unmarried people. But in the cases of situational vaue, younger aged people and white-callar workers recognized more positively. Also, housewives, married people and female recognized more positively than white-callar workers, unmarried people and male. 2. In the results of CHAID analysis, market of general hospital were analyzed by 9 categories and major market were groups who ignored or were unconcerned about newness/classiness and preferred to nearness to residence. The market of university hospital were analyzed by 8 categories and major market were groups who considered to reliability/social reputation importantly. The market of corporate hospitals were analyzed by 8 and major market were group who considered to classiness/newness importantly. Therefore, above results show that health care market can be divided to various market by demand and market segmentation is very important for marketing strategy.

This research was conducted to develop pricing strategy based on understanding about customer perceived value of lodging facilities in national recreation forest. The technique known as PSM (price-sensitivity measurement) was used for analysis of price sensitivity for two kinds of lodging (log-cabin and forest-hotel) and for room sizes (4, 5, 6, 7 persons). PSM questionnaire for on-site survey were distributed to 236 customers on their visit to the six national recreation forests. The main results of this study were as follows: the price sensitivity of big size was higher then small, also, the price sensitivity of log cabin was higher then forest-hotel. Present prices were within the range of acceptable prices except prices of the use of 6 and 7 person of log-cabin. From the result of this study, it was concluded that price adjustment or price promotion strategy would effective for increase in sales and marketing strategies to enhance consumers' perceptions of value should be conducted for two room types by situations.

A precoding strategy is one of the representative interference management techniques in cognitive radio (CR) network which is a typical interference-limited environment. The interference minimization approach to precoding is an appropriate scheme to mitigate the interference efficiently while it may cause the capacity loss of the desired channel. The precoding scheme for the maximal capacity of the desired channel improves the capacity of the desired channel while it increases the interference power and finally causes the capacity loss of the interfered users. Therefore, we propose a precoding scheme which satisfies these two conflicting goals and manages the interference signal in such an interference-limited environment. The proposed scheme consists of two steps. First, the precoder nulls out the largest singular value of the interference channel to mitigate the dominant interference signal based on the interference minimization approach. Second, the transmitter calculates the sum capacities per mode and selects a mode to maximize the sum capacity. In the second step, each mode consists of the right singular vectors corresponding to the singular values except the largest singular value eliminated in the first step. Simulation results show that the proposed precoding scheme not only efficiently mitigate the interference signal, but also has the best performance in terms of the sum capacity in a MIMO-based CR network.

This paper presents an adaptive image interpolation method using a pixel-based neighbor embedding which is modified from the patch-based neighbor embedding of contemporary super resolution algorithms. Conventional interpolation methods for high resolution detect at least 16-directional edges in order to remove zig-zaging effects and selectively choose the interpolation strategy according to the direction and value of edge. Thus, they require much computation and high complexity. In order to develop a simple interpolation method preserving edge's directional shape, the proposed algorithm adopts the simplest Haar wavelet and suggests a new pixel-based embedding scheme. First, the low-quality image but high resolution, magnified into 1 octave above, is acquired using an adaptive 8-directional interpolation based on the high frequency coefficients of the wavelet transform. Thereafter, the pixel embedding process updates a high resolution pixel of the magnified image with the weighted sum of the best matched pixel value, which is searched at its low resolution image. As the results, the proposed scheme is simple and removes zig-zaging effects without any additional process.

Three-phase grid-connected inverters are widely applied in the fields of new energy power generation, electric vehicles and so on. Islanding detection is necessary to ensure the stability and safety of such systems. In this paper, feature recognition technology is applied and a novel islanding detection method is proposed. It can identify the features of inverter systems. The theoretical values of these features are defined as codebooks. The difference between the actual value of a feature and the codebook is defined as the quantizing distortion. When islanding happens, the sum of the quantizing distortions exceeds the threshold value. Thus, islanding can be detected. The non-detection zone can be avoided by choosing reasonable features. To accelerate the speed of detection and to avoid miscalculation, an active islanding detection method based on feature recognition technology is given. Compared to the active frequency or phase drift methods, the proposed active method can reduce the distortion of grid-current when the inverter works normally. The principles of the islanding detection method based on the feature recognition technology and the improved active method are both analyzed in detail. An 18 kVA DSP-based three-phase inverter with the SVPWM control strategy has been established and tested. Simulation and experimental results verify the theoretical analysis.
