일차 반사음의 최적지연시간과 음장의 Preference 판단에 있어서 다른 민족간의 피험자 사이에 차이가 있는지를 알기 위해, 무향실에서 일차 측방반사음을 시뮬레이션하여 지연시간을 가변하면서 주관 Preference 실험을 하였다. 그 결과 일차 반사음의 최적지연시간은 반사음의 레벨이 직접음의 레벨과 같을때 음원의 자기상관함수(ACF) 의 유효지속시간과 일치하며, 음악 모티브가 다르고, 판단 시리즈가 달라도 음장에 대한 Preference판단에 기본적인 차이가 없는 것을 알았다. 또 하나의 음악 모티프에서 다른 2개의 패세지를 사용하여 Preference실험한 결과, 음악 전체에 대한 ACF의 유효지속시간의 변동이 적음을 알았다. 따라서 일차반사음의 최적지연시간은 음원의 ACF와 반사음의 진폭으로부터 예측할 수 있다.

This study designed four types with a different halter-neck shoulder straps of an athleisure brassiere for women in their 20-40s as well as analyzed the shoulder strap pressure, shoulder strap position, subjective sensation, and design preference when wearing them. The design basis was to reduce the pressure at the back of the neck area, to allow the shoulder strap to pass down the neck as far as possible, and to send the anatomically sensitive side neck out as far as possible. As a result, H, which had the best subjective sensation and design preference, had the shoulder strap positioned more towards the shoulder point; in addition, the back of the neck did not pass. It was also found that the shoulder strap pressure near the neck was small. However, E, with the lowest subjective sensation, had the highest shoulder strap pressure and was placed up the neck. This confirmed that the position and pressure of the shoulder strap are variable when influencing the subjective sensation.

본 연구는 음향증폭시스템 중에서 청취자에게 가장 많은 영향을 미치는 스피커 시스템의 배치방식과 스피커 특성변화에 따른 청취자들의 주관적 반응을 명료도와 음향선호도 측면에서 측정하고 비교 분석함으로써 향후 대공간의 음향증폭시스템의 설계 시 활용할 수 있는 기초자료를 제공하고자 하였다. 연구 결과, 전체적으로 실의 흡음률이 결정적인 영향을 미치며, 천장의 흡음률이 높을수록 지각된 명료도는 높아지는 것으로 나타났다. 스피커가 낮게 설치된 경우에는 적용된 스피커의 개수가 많고 지향각이 좁은 스피커들이 사용된 경우의 명료도가 가장 높게 평가되었다. 그러나 전체적으로는 스피커가 천장 흡음면에 가까울수록, 그리고 60도 이하의 좁은 지향각을 갖는 스피커를 사용할 때 높은 명료도를 얻을 수 있으며, 본 연구의 검토범위에서는 8~10개 정도의 스피커가 적용되었을 때 주관적인 명료도 및 선호도가 가장 높게 평가되었다.

The purpose of this study is to examine the difference of judge's gender and age groups in preference of S/S men's suit fabrics, and to analyze the relationship between the preference and the texture by gender and age group. For this study, 60 types of S/S men's suit fabrics were used with variously-composed fibers, such as wool, wool-blended, and PET, thickness, and weight. To evaluate the texture and the preference subjectively, nine ranks' semantic differential scale questions of 22 texture adjectives and preference of 4 apparel items were developed, Through the factor analysis, texture adjectives were classified into 7 categories: "stiffness," "elasticity," "bulkiness," "coolness," "smoothness," and "drapability." Depending on gender and age groups of judges, statistically significant differences on texture factors and the preference were observed. Especially, men under 30 years of age showed a higher grade of stiffness and a lower preference on pants than other groups. The relationship between the texture and the preference was different by gender and age group: Women evaluated a preference of men's suit fabrics in relation to stiffness and smoothness, whereas men did so in relation to stiffness, smoothness, coolness, and drapability. A young age group put more importance on drapability for preference of men's suit fabric.

The purpose of this study is to find out the better washing condition, especially on detergent contents to satisfy the consumer's concern on fabric hand using Drum Type Washer. The hand and preference of washed fabrics by various detergent contents were analyzed through subjective evaluation using questionnaire method in dry and wet state. Wine rank's semantic differential scale questions were developed with 27 kinds of adjective pairs and seven rank's scale questions were to evaluate preference of washed fabrics oil holistic touch, washing and rinsing effect and purchase intention of detergent. Group of trained panelists and untrained women panelists of $30{\sim}40$ years old were participated. The factors affecting consumer's taste for the washed fabrics were analyzed by SPSS 12.0. Smoothness showed relatively higher correlation with preference of washed fabrics on holistic touch, washing and rinsing effect and purchase intention of detergent. There were significant differences in preference of washed fabrics on holistic touch, washing and rinsing effect and purchase intention of detergent by detergent contents when tested in wet state. Fabrics washed with detergents of non-zeolite were appeared to be the preferred ones.

In this study, differences of texture image and preference for men's suit fabrics according to mechanical properties, hand and fabric information were investigated. 55 subjects evaluated texture image and preference of 12 kinds of wool blended fabrics. For statistical analysis, t-test and pearson correlation coefficients were used. The results were as follows: Most of mechanical properties effected on texture images, and bending property and shearing property were effected on tactile preference and purchasing preference. For hand, objective hand values showed correlations with subjective texture images and preferences, but THV had almost no correlations. In sensory images according to presence of fabric information, fabrics were evaluated thinner, lighter, more pliable and smooth by cognition of wool blending ratio. For sensibility images, fabrics were evaluated more refined, intellectual, dignified and less practicable after recognize of wool blending ratio. In preferences, tactile preference was increased and purchasing preference was decreased after recognize fabric information. Therefore, significant differences of texture image and preference were observed according to presence of fabric information.

The Conventional noise control attempts to simply reduce the level of product noise. But it is very straight forward way that we have consider human perception on noise. Since human listening is very sensitive to sound. Evaluation of the sound quality of a Vacuum Cleaner is studied base on human sensibility engineering. In this paper, we choose two Vacuum Cleaners that are sold in Korea and reduced noise control. Comparison Method is used to evaluate noise and preference of Vacuum Cleaner by steps. The sound quality of Vacuum Cleaner noise is analyzed by employing the subjective evaluation and by representing them in terms of the objective quantities. Semantic Differential Method is used to study sound quality Evaluation. To analyze the sound quality of Vacuum Cleaner noise, consider the coefficients of correlation between sound metrics and subjective rating. The linear regression models were obtained for the subjective evaluation and sound quality metrics.

This study aimed to ascertain the most efficient level of compression to be applied on a particular area along the upper extremities whilst developing functionality to prevent musculoskeletal disorders among workers who frequently use their arms. The compression areas were divided into upper arm, forearm, and wrist. The compression levels were applied using three types of bands. Comparisons on these bands' usability were based on evaluations of recorded brainwaves and subjective sensation response. Nine men in their twenties were selected for the experiment. The results revealed that when compression was applied, the left and right occipital lobes, plus the parietal lobe, were activated. Also, the alpha wave activity tended to increase, thereby exemplifying the compression's positive effects. The most physiologically efficient and subjectively preferred compression levels were 1.3 and 2.6 kPa for the upper arm and wrist. Furthermore, the compression level at the forearm should be at least 2.0 kPa.

This study attempts to explain the unique patterns in Korean consumer behavior regarding the luxury fashion brands' donation activities by exploring the moderating effects of corporate ability (CA) and subjective norm (SN) on the relationship between donations and consumers' brand preference, brand trust, and purchase intention. A total of 209 completed questionnaires, collected from online surveys, were analyzed using moderated multiple regression. The result shows that donation amount information positively influences consumers' brand preference, brand trust and purchase intention toward luxury fashion brands. Next, CA strengthens the relationships between donation amount information and consumers' brand trust and purchase intention. SN from the opposite gender compensates for the negative effect of negative donation amount information on consumers' trust toward luxury fashion brands, whereas SN from the same gender does not influence those relationships. This study provides a deeper understanding of luxury fashion brands' donations and consumer responses in South Korea-one of the important test markets for luxury fashion brands to expand their business to Asian countries.
