The surface fibers on the fabric is one of decisive factors which affects human sensory evaluation as well as heat and moisture transfer characteristics. In this study the length and distribution of surface fibers that are extruded from the fabric surface of the wool/wool blend fabrics (14 wool fabrics and 10 wool blend fabrics) and its contribution to subjective sensory evaluation were investigated. In order to quantify the length and distribution of surface fibers, image analysis and wavelet transform technique were introduced. Instant warm-cool feeling of touch, Q$\_$max/, and contact area were also measured and related to the quantified surface fibers. To figure out the effect of surface characteristics on sensory evaluation, human sensory responses to three adjectives which represent surface characteristics and warm-cool feeling of touch were obtained and analyzed. The relationship between the quantified surface fibers assessed by wavelet energy and both warm-cool reeling of touch, Qmax, and human sensory response were discussed.

Now in Korea, many factors-for example, unemployment rate rise, consumer prices, corporate restructuring, etc.-are threatening family economy. Thus many households are faced with an economic crisis. In this circumstances, it is the role of households as a subsystem of family system to keep family and household economy stable for the sake of family growth and development. Economic well-being is differentiated by criterion of household economic status. But it has a large scale of spectrum: household income, asset, consumption, debt and the like. Moreover, these indices have been understood and measured differently by many researchers. In this thesis, we made efforts to distinguish subjective satisfaction from objective satisfaction, and then focus on the former. The data were collected from 399 housewives living in Pusan through questionnaires.

Being able to adopt new information technologies into an organization is very important and critical in the rapid changing, competitive environment. In this research, existing papers related to the information technology acceptance of the 1990s have been studied and analyzed, and the components that affect the use of groupware have been studied by setting up an evaluation model to find the emotional status of the individuals that use groupware. Based upon the survey of 218 groupware users, this study utilized path analysis with LISREL8.12. The major results are as follows: First, perceived usefulness was influenced by training, perceived ease of use. Second, training, groupware self-efficacy, organizational support were determinants of ease of use. Third, training, task ambiguity, task interdependence, organizational support influenced subjective norm. Forth, perceived usefulness, perceived ease of use, subjective norm had positive effects on present usage.

In this paper we studied the reduced subjective timbre space of time-varying tones as well as steady state tones. 45 modified test tones were constructed from the original violin tone in consideration of 4 physical factors: spectrum envelope, inharmonicity, time-varying spectrum and time reversal. The semantic differential (SD) method was used in the listening test. According to the factor analysis, the adjectives can be factorized into 4 groups. The first factor is characterized by the adjectives, 'free', 'broad', 'deep', 'rich', 'strong' and 'reverberant', the second by 'tenor', 'clear', 'bright', 'light' and 'sharp', the third by 'easy', 'smooth', and 'solid', the fourth by 'warm' and 'full'. The first factor, 'richness', seems to be dependent upon the time-varying characteristic of a tone. The second factor, 'sharpness', is shown to play an important role in a time-varying tone as well as in a steady state tone.

A human being's pursuit is that of a better quality of life and the disabled naturally want to do so. But challenged people's lives have not improved apace with the general development of our society as a whole. Specially, in a patriarchal society like Korea, challenged women are in a less favorable situation. Challenged women can enjoy more healthy and more happy life in a given condition. Thus, in this research, we closely examined the women's general characteristics, disabled characteristics, health condition(subjective health condition, experiences of diseases, stress value, etc), satisfaction value of life who have handicaps of limb or/and body. On the 17th of September through the 14th of October '98, a nation-wide retardation compaign was held and 200 people were served by telephone. Then we analysed primary factors on quality of life. As results, monthly income, how they think of their economic level, their subjective health condition, and the stress level that the success depends on self influenced quality of life.

The major purpose of this research was to investigate the relationship of employed and unemployed wives' financial management behavior and financial well-being on the basis of the family resource management system theory. The data were obtained from 660 wives who lived in Seoul 1996. Major findings of this study were as follows: 1. Regardless of the wives' employment status marriage duration and level of wives' education negatively influenced objective financial well-being in the case of unemployed wives but one in the case of employed wives. 2. Both unemployed and employed wives locus of control over their financial situation positively influences subjective financial well-being 3. It was found that personal and managerial factors had effect on subjective financial well-being both for unemployed and employed wives. The path model designed in this research was found to be proven for unemployed but not for employed wives.

This study aimed to evaluate the room acoustical performances of multi-purpose halls, surveying the architectural features and analysing the acoustical characteristics by measurements. In addition, adjectives appropriate for the evaluation of the room acoustical performance in multi-purpose halls were determined through the method of questionnaire survey and subjective evaluation through psycho-acoustic experiment. The results from the experiment were analysed by the correlation analysis and the factor analysis, consequently useful adjectives for the evaluation of acoustical performances in multi-purpose halls were determined depending on the types of performance.

The impact sound of the golf club is one of the major factors to purchase it. Sound quality metrics has been mostly developed for harmonic sounds. Sound quality evaluation techniques for the impact sound have been contrived in this study. Jury test, one of the typical subjective evaluation scheme, is carried out for evaluating the sound quality of 13 different golf drivers, which classification results are assumed to be correct answers. Conventional objective evaluation methods such as Zwicker loudness sensory pleasantness are calculated. Wavelet analysis and instantaneous loudness are applied in order to evaluate the sound quality of transient sounds, which scheme shows better correlation with the results from jury test.

The impressions for odors are subjective and have individual differences. In this study, the Impressions of odors were investigated by covariance structure analysis. 46 subjects (men in their twenty) recorded their reactions to ten odorants by grading them on a seven-point scale in terms of twelve adjective pairs. Their reactions were quantified by using factor analysis and covariance structure analysis. The factors were extracted as "preference", "arousal" and "persistency". The subjects were classified into three groups according to the most suitable causal models (structural equation models). Each group had different causal relationship and different impression structure for odors. It was suggested that there is a possibility to evaluate the subjective impression of odor using covariance structure analysis.

The purpose of this study is to investigate the level of the proporation of household expenditure item and the subjective burden of household due to the private educational expenses. The data used in this study included 761 housewives who have a child of the second grade or fourth grade of primary-school in Seoul. The findings of this study are as follows: First these six variables-educational level of mother household income place of residence grade of child number of child and the expected educational level of child-have significant effects on the private educational expenses. Second the proporation of food expense housing expense clothing expense and miscellaneous expense significantly differ with respect to the private educational expenses.
