Evaluations of fashion products are often influenced by consumers' knowledge of the country where the products were made in. As globalization progresses, country-of-origin information is widely regarded as a powerful cue on consumers' shopping behavior. The purpose of study was to examine the consumer evaluation of apparel products with uni-national or bi-national country of origin. The effect of price level and gender were also investigated. The empirical research design took 2${\times}$2 factorial design with the country-of-origin coincidence (uni-national vs. bi-national) and price (high vs. low) of gender (male vs. female). Consumers' ethnocentrism and country-of-origin interest were taken into account as covariates in the factorial design. The consumers' evaluation of fashion products was measured in terms of brand attitudes and product attitudes. Data from 514 respondents were analyzed with t-test, one-way ANOVA, two-way ANOVA, and ANCOVA. Results of this study affirmed the importance of price information rather than country-of-origin coincidence in brand attitudes and product attitudes. Only for male consumers, interaction effects of price and country-of-origin coincidence had significant eflects on utilitarian attitude. Effects of two covariate variables included in the study were significant for female respondents but not for male respondents.

This paper describes the design processes and evaluation results of a small-sized six-axis force/torque sensor. The new six-axis force/torque sensor including S-type structure has been developed using a parallel plate structure as a basic sensing element. In order tominimize coupling errors, the location of strain gages has been determined based on the finite element analysis and the connections of strain gages have been made such that the bridge circuit with 4 strain gages becomes balanced. Several design modifications result in a similar strain sensitivity for six-axis forces and moments, and the reduced coupling errors of 2.6% FS between each forces and moments. Calibration test results show that the six-axis load cell developed which has light weight of 135g and the maximum capacities of 196 N in forces and 19.6 N.m in moments is estimated to be within 7.1% FS in coupling error.

A study on how fire officer's job satisfaction factors influence space satisfaction rates. This article will conduct regression analysis for the study on these three problems. 'What are the factors of fire officer's job satisfaction?', 'Does space satisfaction rates influence job satisfaction rates?', 'Which job satisfaction factor influence space satisfaction rate?' Therefore, variables were set based on the prior study, and before regression analysis was conducted, variables were purified through analysis on primary factor and reliability analysis, and hypothesis test was done via variable calculation. According to the prior study, factors that influence job satisfaction rates are as following; self-regulation of tasks, ethics and responsibility level, relationship with colleagues, job identity. And regression analysis showed that space satisfaction rates do not influence job satisfaction rates. The writer thinks that it's showing that Korean fire officers tend to prioritize colleague relationship and job identity over space improvements. And the factor that influence job satisfaction rates turned out to be the self-regulation of tasks, and the writer estimates that it's reflecting the hierarchical organization culture of current Korean fire officers. Therefore, future Korean fire station design plans need to consider a space plan that provides fire officer's private self-regulation of tasks.

Currently, obtaining information about the housing studies through the internet web sites is one of the outstanding mediums. Those are of the housings, architecture, interior design, furniture products, hotels and its journals, etc., and out of all those informations are the highly expected value of use. But. it may causes the public users to experience a negative effect, because many of those informations provided on the internet web sites related to the housing studies/informations are not providing an equal quality of information. And measuring the quality is also not easy. This study focuses on the establishment of evaluation criterion for the housing information-related internet web sites. In such a vein, it proposes a clear model to evaluate the information qualities with the 43 questionnaires / examining items. To test the questionnaires/rating items, the analysis has been implemented which has shown the reciprocal effect between the 2 major factors. One major factor with 4 variables on the information searches are (1) the accuracy/reliability of contents and techniques, (2) the design of a picture and communication, (3) the readability and security, and (4) the security of private information, and the other factor with 3variables on the additional services are (1) the diversities of contents and ease of orderings, (2) the abilities of search and e-mail, and (3) the events and after services. This study/rating model will provide the users with a fundamental material in evaluating the quality of housing information on the internet web sites.

A rice mill pilot plant was designed and developed in the basis of the simulation results on the mill plants. The performance of the developed rice mill plant was evaluated, and the simulation model on the mill system was validated with the experimental data in the mill plant. The results of this study were as followings : 1. A rice mill pilot plant with the capacity of 0.5 t/h was designed and developed. 2. The hulled ratio of the mill plant was 87.3%, and the milled rice recovery and the head rice recovery of the cleaned rice were 74% and 87% , respectively. The degree of milling of the cleaned rice was 10.6% with a high polish. The intensity of the cleaned rice appeared high compared with that of the milled rice in the analysis of whiteness test using an image processing system. 3. The bottleneck, processing time, and production amount of the developed mill system almost coincided with those of the simulation of the rice mill plant. The developed simulation model of the rice mill plant was proven to be applicable to the design of a rice mill plant through experiments.

The purpose of this study is to investigate the preference of the hand and the sensibility image of underwear textiles according to seasons. According to a recent survey of 109 college students, using a 7 scale evaluation to the preference of the hand and the sensibility image among 13 summer and 10 winter underwear textiles. The data was analyzed through mean, SD, factor analysis, t-test, Person correlation analysis and regression analysis using SPSS Win 11.0. The summer underwear textiles were classified according to six tactile factors: stiffness/surface unevenness, weight, elasticity, moistness, extension, and warm-cool and 3 sensibility image factors: elegant individual, modern, and sporty-casual. The winter textiles were classified according to six tactile factors: stiffness/surface unevenness, elasticity, warm-cool, drapability, moistness and flexibility and divided into 2 sensibility images: modern elegant and sporty-casual. Factors expressing hand and sensibility image according to season showed significant difference. In the summer, weight, in the winter, drapability and flexibility showed significant difference at the hand factor evaluation. The hand factors: weight, warm-cool and modern sensibility image factors effect the preference of summer underwear textile, also the hand factors-elasticity, stiffness/surface unevenness and the sensibility image factor-easy-sport-casual-effect the preference of winter textiles. Therefore, the thin, light, and cool textiles which are also gorgeous and sporty-casual are preferred for summer underwear textiles while soft, simple and comfortable textiles are preferred for winter textiles.

It is essential to understand the infrared signature of a naval ship to survive against various missile attacks under variable environmental conditions. As guided missiles are developing to equip more accurate IR seekers, research works for countermeasure and IR stealth technology are strongly required. But challenging works are continuously suggested for predicting and analyzing IR signal status of naval ships to achieve low observable performance under various weather conditions, variable missions and developing threats. In this study, overall guidelines of setting design criteria for low observable ships are proposed by considering varying environmental conditions including daily and seasonal variations. Test and evaluation criteria for newly constructed ships for target and background temperature difference is proposed as a design criteria which can be predicted by change of condition and ship's speed. Through the proposed techniques and procedures, it is expected to establish the measurement and evaluation criteria by using temperature, IR Signal differences between the ship and the background.

New EMS equipment and apparel have been developed to deliver electrical stimulation to the entire body at once. Textile or silicone electrodes are now replacing gel electrodes typically used in EMS equipment. This study analyzes the impact of design elements and electrode specifications of EMS smart clothing on comfort, mobility, and usability. Three types of EMS smart clothing were selected- whole body suits, top and bottom sets, and pants-and analyzed for product design, materials, and electrode pads. Subsequently, wearability evaluations were conducted on 10 participants. Results indicated that the EMS electrodes used in all three samples were silver(Ag)-based conductive materials, with some electrodes incorporating foam to improve skin adhesion. Wearability evaluations revealed that ease of wear and mobility were significantly influenced by product type and size. To improve appearance and comfort, EMS smart clothing should incorporate two layers or outer coverings. Additionally, the design should allow for adjustments in arm and thigh circumference, ensuring electrodes fit closely to the body.

Generally, durability of concrete structures under marine environment is grossly declined by detrimental ions such as chlorides, which penetrate concrete and was diffused to corrode reinforcing rod. Therefore, chloride diffusion properties in concrete are important for durability evaluation and design of concrete structure. For estimation of chloride diffusion coefficient in concrete, both evaluation methods are used for steady state and non-steady state derived from Fick's 1st and 2nd law, respectively. However, as it is very difficult to evaluate diffusion coefficient for non-steady state like service environment where concrete is actually exposed, indirect evaluation method by laboratory accelerated test is generally used. In this study, comparison of chloride diffusion behavior was investigated for fixed mix proportion and age of concrete using four accelerated test methods based on domestic and foreign standards. From test results, only relative comparison between concrete mixtures was possible using ASTM C 1202 test, and diffusion coefficient for steady state was estimated as low as 1/10 of that for non-steady state. In addition, diffusion coefficient estimated by immersion test was similar to result by NT build 492 test.
