  • In this study, metrics for evaluation of heavy-weight impact noise were investigated. Heavy-weight impact noises generated by impact ball were recorded in real apartments using binaural microphone. Those sounds were classified into three groups according to frequency characteristics in order to control aspects which affect subjective responses to heavy-weight impact noise. Sound sources for auditory experiment were selected based on the classification result. Then auditory experiments were conducted to investigate the relationship between level indices and subjective responses. The results showed that $L_{Aeq},\;L_{Amax}$ and $LL_z$ as well as $L_{iFmax,AW}$ were highly correlated with subjective response. Therefore, $L_{Aeq}$ and $L_{Amax}$ can be used as metrics for evaluation of heavy-weight impact noise. In further studies, it is needed to verify classification of heavy-weight impact noise generated by bang machine and impact ball.

  • In Jøsang's subjective logic, the fusion operator is not able to fuse three or more opinions at a time and it cannot consider the effect of time factors on fusion. Also, the base rate (a) and non-informative prior weight (C) could not change dynamically. In this paper, we propose an Improved Subjective Logic Model with Evidence Driven (ISLM-ED) that expands and enriches the subjective logic theory. It includes the multi-agent unified fusion operator and the dynamic function for the base rate (a) and the non-informative prior weight (C) through the changes in evidence. The multi-agent unified fusion operator not only meets the commutative and associative law but is also consistent with the researchers's cognitive rules. A strict mathematical proof was given by this paper. Finally, through the simulation experiments, the results show that the ISLM-ED is more reasonable and effective and that it can be better adapted to the changing environment.

  • The effect of spatial factors on subjective responses to heavy-weight floor impact noise was investigated. Heavy-weight impact noises were generated and recorded in several apartments and a testing building using impact ball and binaural microphone to measure IACC of the noises. Just noticeable differences (JNDs) of IACC and SPL of heavy-weight impact noise were also investigated. Auditory experiments were conducted using method of limit. It was found that the JNDs of IACC and SPL were 0.12 and 1.5dB, respectively. Contribution of IACC and SPL to annoyance of heavy-weight floor impact noise is being further investigated.

  • This study conducted an analysis of the correlations among menopausal symptoms of middle-aged women, their exercise performance and subjective health conditions on those 417 middle-aged women aged 40-59 years, residing in Seoul and the Kyongki Province area, from December 6, 2000 through Jun. 20, 2001, using the SPSS 10.00 program. Resultant findings were revealed, as follows: 1. A difference was represented in general characteristics between menopausal symptoms of middled-aged women and variables such as satisfaction with life, sexual life, diseases, the presence or absence of surgical operations; a difference between exercise performance and variables such as age, the presence or absence of vocations, weight control, satisfaction with life, and sleep; and also a difference between subjective health conditions and variables such as weight control, satisfaction with life, diseases, and the presence or absence of surgical operations. 2. Furthermore, a difference was revealed between the levels of menopausal symptoms by exercise performance and variables such as mental and physical symptoms and psychological symptoms. 3. The group of good exercise performance showed higher subjective health conditions as to subjective health conditions by the levels of exercise performance. 4. The better their subjective health conditions, the lower their menopausal symptoms as to menopausal symptoms by subjective health conditions. 5. A negative relationship was disclosed between menopausal symptoms and exercise performance; a positive relationship between exercise performance and subjective health conditions; and a negative relationship between subjective health conditions and menopausal symptoms.

  • In this study, the effect of temporal variation of IACC on subjective response to heavy-weight floor impact noise generated by impact ball was investigated. Subjective evaluation was conducted to investigate the effect of temporal variation of IACC on perception of heavy-weight floor impact noise using paired comparison test. The results showed that the effects of SPL and temporal variation of IACC on the annoyance of heavy-weight impact noises were independent and the contribution of SPL was much larger than that of temporal variation of IACC. It was also found that the effect of IACC is larger than temporal variation of IACC comparing to previous study.

  • Purpose: The purpose of the study was to investigate the relationships between objective obesity, subjective obesity, body attitudes and dieting among college women. Method: The convenience sample consisted of 531 women. BMI was calculated based on self-reported weight and height. Body Attitudes Questionnaire (BAQ) was used to evaluate attitude toward women's body. Result: BMI mean score was 19.75. Based on BMI, 84.2 percent of the subjects were in a normal weight range and 0.9 percent of the subjects were obese. However, 26.9 percent of the subjects evaluated themselves as obese. Forty-one percent of the subjects were on a diet to reduce thier body weight. Body attitudes were associated with BMI and subjective obesity. BMI of the dieters was higher than that of the subjects who were not on a diet. Subjective obesity was associated with dieting. BAQ subscales except 'attractiveness' were associated with dieting. Conclusion: Many subjects were on a diet since they wanted to be thinner. Body attitudes were associated with dieting. Therefore, proper education is needed in weight management for young adult women.

  • This study was conducted to establish the effects of subjective body-forming perception on weight-controlling behavior and weight loss, and to suggest the need for proper information and education. Using the data from the National Health and Nutrition Examination Survey conducted in the 6th period (2013-2015), 6,238 women aged 19 and over who have a body mass index of $18.5-25kg/m^2$ were analyzed. As a result, the higher the level of education and income level, the higher they were perceived to be obese, the more they chose to lose exercise and diet in order to lose weight across the board. The weight loss effort rate was higher in the obese body type recognition group, but the body weight type was the highest in the one year body weight change group (p < .001). As a result, subjective perception of body shape affected not only weight control behavior but also weight change (p < .001). Accordingly, it is necessary to have a systematic education on healthy weight-controlling behaviors, proper body image, and healthy body type recognition.

  • This paper discussed the assessment of hand of Tencel denim fabrics finished by enzymatic hydrolysis. The subjective hand and the preference of Tencel denim fabrics were evaluated using the developed scale. The factors affecting consumers taste for Tencel denim fabrics were analyzed by statistics using SAS program. Also, the effects of cellulase treatment on the properties of Tencel denim fabrics were evaluated by the subjective hand measurements. The results are as follows: As the weight loss increased. fabrics were evaluated as finer, smoother, softer, warmer, more refined (surface properties), more compact and weaker (durability), more flexible, flossier, lighter, softer, thinner (sense of weight), more elastic, and less wrinkly (shape recovery). Fabrics were evaluated to have the dry touch regardless to the rate of weight loss (moisture properties). Overall hand preference of Tencel denim fabrics was in the side of not preferred. Hand of Tencel fabrics seems not to appeal to Korean people. Color preferences were not significantly different among five groups. The correlations between subjective hand and preference showed that fine, smooth, flexible, warm, refined, loose, soft, dry touches were preferred in Tencel denim fabrics.

  • This study compares Customer Satisfaction Index(CSI) and the weight for each dimension by applying various methods of weight calculation and attempts to suggest some implications. For the purpose, the study classified the methods of weight calculation into the subjective method and the statistical method. Constant sum scale was used for the subjective method, and the statistical method was again segmented into correlation analysis, principal component analysis, factor analysis, structural equation model. The findings showed that there is difference between the weights from the subjective method and the statistical method. The order of the weights by the analysis methods were classified with similar patterns. Besides, the weight for each dimension by different methods of weight calculation showed considerable deviation and revealed the difference of discrimination and stability among the dimensions. Lastly, the CSI calculated by various methods of weight calculation showed to be the highest in structural equation model, followed by in the order of regression analysis, correlation analysis, arithmetic mean, principal component analysis, constant sum scale and factor analysis. The CSI calculated by each method showed to have statistically significant difference.
