  • In the diverse modern era, individuals are actively striving to develop and demonstrate their capabilities . As a means of cultivating interest in hanbok and differentiatedabilities , there exists a national qualification verification for hanbok technician. This study focuses on using Saekdong-jeogori pattern that is suitable for design and allows for accurate pattern production in a short time for beginners taking the practical test for hanbok technicians. We analyzed five experimental Saekdong-jeogori patterns, from which the final patterns for research were derived through appearance tests on the first table evaluation and the second outfit evaluation. The Saekdong-jeogori pattern-1 for research utilized the body values presented by beginners taking the hanbok technician qualification verification, while the rest were calculated or applied using equivalents. The godae point and armhole depth were calculated based on the chest circumference, and the armhole curve, sleeve shape, doryeon line, and sleeve-end were drawn, regardless of the changes in the figures, using equal parts. The Saekdong-jeogori pattern-2 provided activity by vertically lowering the side line from the end of the armhole, and the keotseop line was drawn by moving 1 cm from the width of the Kit to the armhole line. The seopko was raised 0.2 cm from the keotseop reference line and0.2cm , and was supplemented by its connection to a natural curve.

  • Purpose - Salesperson perceptions of the fairness and accuracy of a performance evaluation system were examined by managerial and professional employees of large organization. The performance evaluation process is central to many personal decisions such as attitude for job and sales performance. This study investigates the relationship between perceived evaluation fairness, job satisfaction, organizational commitment, and sales performance. The main purpose of this study is to develop and empirically test a comprehensive model of salespersons' perceived evaluation fairness on sales performance. For this purpose, we identified the structural relationship between perceived evaluation fairness, job satisfaction, organizational commitment, and sales performance. Also we investigate the mediating effects on job satisfaction and organizational commitment between perceived evaluation fairness and sales performance. Research design, data, and methodology - To empirically test these relationships, data were collected by in-depth interviews from sales managers and questionnaire surveys from 300 salespersons who work for sales area (credit card company, insurance company). Demographically, the overall sample was 91.6% female, 77.9% 30s and 40s, and 34% college educated, with an average tenure with their present organizations of 4 years. The questionnaire was composed of total 20 items dealing with frequency, quality, and consequences of perceived evaluation fairness, job satisfaction, organizational commitment, and sales performance.

  • The evaluation of the noise for the an existing engine was carried out to improve the current noise level. The applied techniques were 1m air-borne noise, combustion noise analysis, torsional analysis at the front pulley and sound pressure intensity. In addition, the evaluation of the possibility to the noise reduction by means of wrapping the parts was performed to propose the detailed information in engine design. In view of the obtained results, the following countermeasures were recommended to reduce the current noise level through the above methods. Furthermore, in order to assess the influence of combustion noise on the overall engine noise, the noise test was also performed by the change of intake air temperature up to 5$0^{\circ}C$ in steps of 1$0^{\circ}C$. Finally, the fixed design specifications to reduce the engine noise will be decided in consideration of the test data for proto type engine.

  • This paper presents a subsequent research work on the roller design of IRB(isolation roller bearing) seismic isolation device presented in Part 1 by focusing on heat treatment. The hardness and friction factor are very important factors of material and after-treatment process selection. Normally, roller bearing consists of roller and retainer. The roller gets high pressure constantly, while the retainer gets tensile and compressive stress. Therefore, sensitive material selection and heat treatment of each part is quite important. In this experimental evaluation, carbon steel, chrome special steel and others are employed and their characteristics after heat treatment are identified. Each material is prepared by refining high frequency heat treatment. The friction factor and static load capacity of manufactured material are experimentally identified and destructive test of material is processed. Optimal material and heat treatment conditions for IRB roller bearing are determined based on experiment results.

  • The objectives of this study were to identify the dimensional structure of female impression formation based on ornaments and color of jacket, and to analyze the effect of ornaments, color of jacket, and perceiver's gender on impression formation. The experimental design was 3$\times$4$\times$2(ornaments$\times$color of jacket$\times$gender) factorial design by 3 independent variables. The stimuli of color photographs of female model and the semantic differential scale were used. Samples were 288 college males and females. The data were analyzed by factor analysis, ANOVA, duncan's multiple range test, and t-test. Four factors derived to account for the dimensions of impression formation. These were potency, elegance, evaluation, youthfulness, and feminine. Wearing of large ornaments(a necklace and earrings) had a negative effect on impression of elegance and positive on potency. Red jackets increased the impression of positive evaluation, potency, feminity, and youthfulness. On the jackets of achromatic color such as white and black, wearing of large ornaments increased the effect of potency, and large ornaments increased matured impression on black jacket. The results of this study mean that perceiverss used large ornaments and red jackets as a salient cue.

  • Cognitive model, that is cognitive architecture, is the model expressed with computer program to show the process how human solve a certain problem and it is continuously under investigation through various fields of study such as cognitive engineering, computer engineering, and cognitive psychology. In addition, the much extensive applicability of cognitive model usually helps it to be used for quantitative prediction of human Behavior or Natural programming of human performance in many HCI areas including User Interface Usability, artificial intelligence, natural programming language and also Robot engineering. Meanwhile, when a system designed, an usability test about conceptual design of interface is needed and in this case, analysis evaluation using cognitive model like GOMS or ACT-R is much more effective than empirical evaluation which naturally needs products and subjects. In particular, if we consider the recent trend of very short-end term between a previous technology development and the next new one, it would take time and much efforts to choose subjects and train them in order to conduct usability test which is repeatedly followed in the process of a system development and this finally would bring delays of development of a new system. In this study, we predicted quantitatively the human behavior processes which contains cognitive processes for menu selection in touch screen interface through ACT-R, one of the common method of usability test. Throughout the study, it was shown that the result using cognitive model was equal with the result using existing empirical evaluation. And it is expected that cognitive model has a possibility not only to be used as an effective methodology for evaluation of HCI products or system but also to contribute the activation of HCI cognitive modeling in Korea.
