The purpose of this study is to classify men's fashion leadership into groups and analyzed the differences for the actual conditions of cosmetics purchasing and evaluation criteria. Questionnaires are being administered from 163 men in their 20's and 30's living in Deagu Metropolitan City and Kyungbook. Frequency, factor analysis, reliability analysis, cluster analysis, ANOVA, Duncan-test, and $X^2$-test are all used for data analysis. Our findings are as follows. Men's fashion leadership is being categorized into fashion opinion leadership, innovative communicator and fashion innovator. Cosmetics evaluation criteria are service/aesthetic, ostentatious, function, and economy. Men's fashion leadership is classified into three groups: fashion laggards, fashion leaders, and fashion followers. Males show no significant differences in the function of cosmetics evaluation criteria by the groups but they show significances in service/aesthetic, ostentatious, and economy. Groups display distinctions between the sub-variables in the actual condition of cosmetics purchasing such the place of purchase, companionship when buying cosmetics, and average monthly purchase amount. Although the cosmetic markets for men show high average growth rates per year, cosmetic interests at the age of twenties and thirties are generally low, and cosmetics are not actively used. The customers' experience of using merchandise not only provide the opportunities of trying beforehand, but also lead to the role of information transfer, thus, it can be positively applied to active marketing. In addition, it can be expected that the low-priced cosmetic markets are guaranteed to obtain loyal customers through repurchasing and maintain long-term relationships by providing fashion followers with several promotional events.

According to the development of service industry recently, the use of call taxi service is increased to use a taxi more comfortably. But related firms hesitate to construct a call center on account of enormous expense of constructing. Hence we developed the system that can minimize expense of constructing a call center which use a cellular phone. The proposed system is different from the existing call system of using a terminal method. we designed by applying UML(Unified Modeling Language) the system that can integrate and manage operations of customer management, driver management, order management and settlement of accounts etc. more efficiently using CTI(Computer Telephony Integration). Then the designed system is constructed by using Visual Basic 6.0. For implementing CTI more effectively, calling number of customer is received in PC using CID that is commercialized and then the customer's information is retrieved in the Database in real-time. The system proposed in this paper is possible to construct at low expense, can improve customer service level through an efficient customer management solution.

The purpose of this research is to investigate the relationships among the perceived satisfaction, the perceived the trust, the commitment, the key features for mobile phone, the brand image, the switching cost and the repurchasing intention. We also examine the differences between Korean and Indonesian markets concerning the relationships of these key successfactors. The structural model is tested with the data form each of the sub-samples (i. e. Korean and Indonesian users taken separately). Properties of the casual paths, including standardized path coefficients, the significance of difference, and variance explained for trust, satisfaction, commitment and repurchasing in the hypothesized model, are presented. This study indicated that hardware (sound quality, LCD display, design) user interface (GUI, Menu, Key pad) and extra functions (camera phone, wireless internet, MP3 player) are the three important factors effecting the trust and the satisfaction. The proposed model has been newly tested from the technological prospective in order to get the more practical result. Following the model test, we conduct a test of the differences in path coefficients between Korean and Indonesian users. MSEM show that, compared to Korean market, Indonesian had more emphasized on extra-function for the mobile phone as well as giving more influence to the satisfaction from the brand image. It means Korean market consider the extra-function as basic or no-premium points. And the satisfaction has been effected by switching-cost in Korea but the trust in Indonesia. Other interesting result from the structural weight invariance indicate that, compared to Korean market, the brand-image has effected the satisfaction in addition to placing more the trust on determining the commitment in Indonesia.

This study is about comparing the mobile user experience of Facebook and Instagram which are most often used among the recent SNSs by the people in their 30s and under. This study analyzed the user experience level after dividing the user experience factors through the Creating Pleasurable Interfaces model, and suggested the mean analysis as well as the result of Wilcoxon rank test which is a nonparametric statistics method. As a result of study, the Display information visually factor in functional factor and the configuration of the main page in convenient factor were a statistically significant difference in the mobile user experience of Facebook and Instagram. It is expected that this study may help seeking the user experience factors to be promoted preferentially in a competitive situation through the statistical comparative evaluation of the experience of two SNS users.

Recently, patterned magnetic films and elements attract a wide interest due to their technological potentials in ultrahigh-density magnetic recording and spintronic devices. Among those patterned magnetic structures, magnetic anti-dot patterning induces a strong shape anisotropy in the film, which can control the magnetic properties such as coercivity, permeability, magnetization reversal process, and magneto-resistance. While majority of the previous works have been concentrated on anti-dot arrays with a single magnetic layer, there has been little work on multilayered anti-dot arrays. In this work, we report on study of the magnetic properties of bilayered anti-dot system consisting of upper perforated Co layer of 40 nm and lower continuous Ni layer of 5 nm thick, fabricated by photolithography and wet-etching processes. The magnetic hysteresis (M-H) loops were measured with a superconducting-quantum-interference-device (SQUID) magnetometer (Quantum Design: MPMS). For comparison, investigations on continuous Co thin film and single-layer Co anti-dot arrays were also performed. The magnetic-domain configuration has been measured by using a magnetic force microscope (PSIA: XE-100) equipped with magnetic tips (Nanosensors). An external electromagnet was employed while obtaining the MFM images. The MFM images revealed well-defined periodic domain networks which arise owing to the anisotropies such as magnetic uniaxial anisotropy, configurational anisotropy, etc. The inclusion of holes in a uniform magnetic film and the insertion of a uniform thin Ni layer, drastically affected the coercivity as compared with single Co anti-dot array, without severely affecting the saturation magnetization ($M_s$). The observed changes in the magnetic properties are closely related to the patterning that hinders the domain-wall motion as well as to the magneto-anisotropic bilayer structure.

Currently, environmental contaminants that can cause Aromatic types of hydrocarbons, less than 1% made of Aromatic Free kind of used products, soybean oil products with linseed oil with the products, rice products using a wide range of environmentally ecological ink since 2000 is released quickly. All materials used in printed material, if the green is the best way to print the composite materials in industrial applications, because each process on the print quality and productivity, there can be many differences in this experiment because it accounts for a large proportion in the print general ink in the ink section and the International color standards(ISO2846-1:2006) certified ecological ink were compared. Therefore, in this paper has the ink released from the same company, each common general ink and ecological ink in the same condition which results were focused on whether the emerging international color standard(ISO 2846-1:2006) recognized for environmentally ecological ink printed color reproduction of the actual offset(color reproduction) how conformity to ISO 12647-2 standard color on the basis of the offset would check Color Reproduction. Based on the results of the experiments of this study, given the ecological ink coated paper, uncoated paper both color difference and the gamut of the ISO 12647-2 standard is suitable for ecological ink, the ink's color gamut reproduction, even more than existing international standards, there is no confirmed that the correct color reproduction possible. Using environmentally ecological ink industries is expected to respond to environmental policy.

This work describes an 8b 200 MHz 0.18 urn CMOS analog-to-digital converter (ADC) based on a pipelined architecture for flat panel display applications. The proposed ABC employs an improved bootstrapping technique to obtain wider input bandwidth than the sampling tate of 200 MHz. The bootstrapuing technique improves the accuracy of the input sample-and-hold amplifier (SHA) and the fast fourier transform (FFT) analysis of the SHA outputs shows the 7.2 effective number of bits with an input sinusoidal wave frequency of 500 MHz and the sampling clock of 200 MHz at a 1.7 V supply voltage. Merged-capacitor switching (MCS) technique increases the sampling rate of the ADC by reducing the number of capacitors required in conventional ADC's by 50 % and minimizes chip area simultaneously. The simulated ADC in a 0.18 um n-well single-poly quad-metal CMOS technology shows an 8b resolution and a 73 mW power dissipation at a 200 MHz sampling clock and a 1.7 V supply voltage.
