The purpose of this research was to examine the subjective evaluation of sensory images and preferences according to the mechanical properties of linen and ramie fabrics for summer shirts. 54 male and female teachers evaluated the sensory images and preferences of 6 specimens of linen and ramie fabrics sold on the market. For statistical analysis, factor analysis, Mann-Whitney and Kruskal-Wallis test, Pearson correlation, and regression were used. The results were as follows: The sensory images of shirt fabrics were classified into 5 factors: 'smoothness', 'stiffness', 'elasticity', 'dry/coolness', and 'wetness'. There were partially significant differences by the gender and age in the sensory images for the shirt fabrics. Females were more sensitive than males for the 'stiffness', 'elasticity', and 'wetness' factor and the evaluators in their 20's felt fabrics were stiffer. The sensory images showed many correlations with the mechanical properties of fabric mostly. The preferences of tactile and purchase were no different according to the gender and age. They preferred a thin and soft sensory image as like ramie/cotton blended fabric and bamboo fabric for summer shirts. The significant sensory image factors affecting tactile preference were 'smoothness', 'dry/coolness', and 'elasticity', and the ones affecting purchase preference were 'smoothness', 'stiffness', 'dry/coolness', and 'elasticity'. W, WT, MMD, and G properties of the mechanical properties of fabrics affected the tactile preference for summer shirt fabrics.

BACKGROUND/OBJECTIVES: Excessive sugar intake is one of the causes associated with obesity and several chronic diseases prevalent in the modern society. This study was undertaken to investigate the effect of parenting variables based on the theory of planned behavior, on the sweetness preferences and sweets intake of children. SUBJECTS/METHODS: Parents and their children (n = 103, aged 5-7 years) were enrolled to participate in a survey for this study, after providing the required informed consent. Parents were asked to fill out a self-administered questionnaire at their residence. The sweetness preference test for children was conducted at a kindergarten (or daycare center) by applying the one-on-one interview method. RESULTS: The children were divided into two clusters categorized by the K-mean cluster analysis: Cluster 1 had higher sweetness preference (0.42 M sugar, 35%; 0.61 M sugar, 65%); Cluster 2 exhibited lower sweetness preference (0.14 M sugar, 9.5%; 0.20 M sugar, 9.5%; 0.29 M sugar, 81%). Cluster 1 had a higher frequency of sweets intake (P < 0.01), and lower sweets restriction (P < 0.05) and nutrition quotient score (P < 0.05). Sweets intake was negatively correlated with the nutritional quotient (r = -0.204, P < 0.05). The behavioral intention of parents was higher in cluster 2 (P < 0.05), while affective attitude, feeding practice, and reward were higher in cluster 1 (P < 0.001, P < 0.05, and P < 0.01, respectively). Furthermore, behavioral intention of parents showed a negative correlation with affective attitude (r = -0.282, P < 0.01) and feeding practice (r = -0.380, P < 0.01), and a positive correlation with subjective norm (r = 0.203, P < 0.05) and parenting attitude (r = 0.433, P < 0.01). CONCLUSIONS: This study indicates that the sweetness preferences and sweets intake of children is related to the parent's affective attitude, feeding practice and reward. We suggest that to reduce the sugar consumption of children, guidelines for access to sweets and pertinent parenting practices are required.

This study was conducted as a comparative analysis, using the SPSS 17.0 program for a survey conducted from March to July 2013, on the level of perception and preference factors of Koreans and Americans residing in Virginia, USA(89 male and female adults of 20 years of age or above). For the information on the degree of obesity, a survey was used and the subjects provided with their heights and weights. The researcher used this data to calculated their BMI and distinguished the degrees of obesity. For the BMI, the obesity diagnosis of Korean Society for the Study of Obesity was used for Koreans, and the WHO's obesity diagnosis on adults were employed for Americans. First, regarding the Korean participants, the level of obesity appeared in the order of normal (79.6%), overweight (14.3%), and underweight (6.1%). Also, the level of perceptions of their health conditions appeared in the order of average (51.7%) and good (34.7%). No one perceived their health to be in poor condition. Meanwhile, for the American participants, the order was as follows: overweight at about 45%, normal weight at about 35%, obesity at about 12.5%, and underweight at about 7.5%. In terms of the level of perception of health during ordinary times, about 55% of the American participants answered that they are in good health. Therefore, the Americans were found to perceive their health to be in relatively better condition than the Koreans residing in the USA. Also, concerning the level of interest in health while eating food at ordinary times, the American participants were discovered to be more interested (about 62.5%) than the Korean participants. The research on their preference for salty taste was conducted as a survey, and the subjects were asked to choose an item according to their subjective feeling. Regarding the preference for salty taste, both Koreans and Americans residing in the USA responded as moderate. However, a higher proportion of Americans than Koreans responded to favor salty taste. Concerning the reason for their preference for salty taste, Koreans responded with various reasons whereas Americans mostly responded that it is because they eat salty food frequently. For any changes in dietary behavior related to eating salty food, both Korean and American respondents thought that the amount of their daily intake of salt is appropriate and that they consider taste as most important in selecting a snack. Based on the above data, the results of this research indicate a need for actual improvement in the diet with regard to salty food along with diverse policies for promoting life with a low salt diet in future.

The purposes of this study were to determine consumers' characteristics that were shown according to their fashion leadership through examining the differences found with consumers' self-conception like the body cathexis and self-efficacy and clothing shopping orientation. The data were collected from 263 female college students using questionnaire. The results could be summarized as follows: First, the household income, subjective social class and clothing expenditure of the fashion leader group was larger than those of the fashion follower and laggard groups. Second, the fashion leader group showed higher body cathexis than the fashion follower and laggard groups in the lower body, the abdominal region, the bust shape, and the whole body shape. Thirdly, the higher was the fashion leadership, the higher was the self-efficacy. Forth, it was proved that the higher was the fashion leadership, the higher were the clothing shopping orientation such as home-shopping preference, hedonic shopping, impulsive purchasing, and brand loyalty.

A psychophysical measurement technique called "magnitude estimation" was used to evaluate several interior design alternatives for a high speed train. Pas- senger activity, seat direction, and passenger age were manipulated by using a three factor within-subjects experimental design. During the experiment, two dependent measures, a line length and a numerical estimate for each alternative design were collected to validate the experimental procedures. The results showed that pasnger seats arranged in the same direction as the running direction of the train was favored nine times more than the opposite. Also, the subjects preferred listening to music in a coach train to the other activities such as reading newspaper, watching a movie, and resting. This paper demonstrates that a psychophysical technique can be sued in the design of a development process, especially when it is difficult to quantify design variables such as subjective opinion or preference, etc.

Most existing telephone networks transmit narrowband speech witch has been bandlimited below 4 kHz. Compared with wideband speech up to 8 kHz, narrowband speech shows reduced intelligibility and a muffled quality. Bandwidth extension is a technique to generate wideband speech by reconstructing 4-8 kHz highband speech without any additional information. This paper presents experimental results of the bandwidth extension adopted for 4800 bps CELP speech coder. In this experiment, we examine various methods for reconstruction of wideband spectrum and excitation signal, compare and analyze their performance by performing the subjective preference test and measuring the cepstral distortion.
