The starch content of apples, which is related to the maturity and ripeness, was quantified by using a computer vision system. The stained area was measured by image analysis when an apple slice was stained with KI/I$_2$ solution. The ratio of stained area of the apple slice to its whole area, so called the starch index, was defined as an indicator of the starch content. When Tsugaru apples were manually sorted into immature, turing and mature groups, their starch indices were 0.374, 0.312 and 0.129, respectively. The starch index had relationships to various physicochemical properties of Tsugaru apples. At the statistically significant level of 0.1%, it was correlated with the pH value, bio-yield force, rupture force and color of intact and skin-removed apples. At the 1% significant level, it had the correlation with the density and moisture content.

The purpose of this study was to measure customers' perception of brand personality and self-image of family restaurants and compare the congruity between brand personality and customer-perceived self-image according to customers' general characteristics. Self-administered questionnaires were completed by 377 customers, and data were analyzed by frequency, chi-square, paired samples t-test, factor, reliability, cluster, and discriminant analyses. Results of the study were as follows: factor analysis of brand personality and customer-perceived self-image as 5 factors, i.e., sincerity (10 variables), excitement (8 variables), competence (7 variables), sophistication (6 variables), and ruggedness(5 variables). As a result, the averages of brand personality and self-image of family restaurants were $2.93{\pm}0.39$ and $3.24{\pm}0.52$, respectively. Cluster analysis divided subjects into two groups according to congruity between brand personality and customer-perceived self-image of family restaurants: congruity group and incongruity group. The two groups were differed from one another in general characteristics. Limitations and future research directions are also discussed.

This study was performed to develop experimental model for milling degree and whiteness from analysis the CBB (colored bran balance) index using NMG dying and image processing. The endosperm layer increased and the pericarp, aleurone layer and CBB index decreased as the milling degree and whiteness increased. So, CBB index was closely linked to milling degree and whiteness. A empirical CBB index model was developed according to the milling degree and whiteness. The model were found to fit adequately to all test data with a coefficient of determination of 0.99, and therefore the CBB model proved to be quite applicable.

This study was undertaken to examine body image distortion among female adolescents and identify related factors. Raw data from the 14th Korean Youth Health Behavior Survey were used. The proportion of participants exhibiting body image distortion was 39.5%, with the ratio being higher among female students of normal weight as compared to underweight female students. Logistic regression revealed that the risk of having a distorted body image was higher among high school females than in middle school females having lower subjective academic performance and household economic status. In addition, the risk of having a distorted body image was higher for students who drank alcohol when compared to students who did not drink, for the group engaging vigorously in physical activity (exercise) more than three times per week as opposed to the group exercising less than three times per week, and for the group consuming less than one serving of fruit per day as compared to the group consuming more than one serving of fruit per day. Taken together, the results of this study indicate that continuous nutrition education needs to be provided so that adolescents can correctly perceive their body images and form desirable eating habits.

This study investigated the effects that corporate social responsibility (CSR) had on the credibility and image of a food corporation by analyzing the purchasing intention and food purchases of consumers. This analysis was undertaken in an attempt to establish a marketing strategy that meets consumer demands, and the results showed that all CSR activities undertaken by the food corporation had a positive effect on the reliability and image of the corporation and on consumers' purchase intention. The results indicate that the ethical aspect of the CSR activities had the greatest effect while their charitable aspect had the least effect on the reliability and purchase intention of the customers regarding the food corporation. Thus, it appears that establishing of suitable ethical doctrines and guidelines for corporate management by food corporation is effective in emphasizing the ethical aspects of their policies through transparent management by means of fair trade.

Purpose: The goal of this study was to examine body image satisfaction and perception according to weight status, and to investigate those associations with dietary habits and nutritional status among preadolescent children. Methods: Body image and dietary habits and intake were assessed in 134 elementary school students in grade 4. Children were categorized according to normal and overweight or obese groups. Figure rating scales were used to assess body image perception (identification of perceived current body size) and dissatisfaction (difference between perceived current body size and ideal body image). Results: There were sex differences in body image perceptions. Normal-weight girls, overweight or obese girls and boys were more likely to desire a leaner body size than their perceived body size compared with normal-weight boys. Body image satisfaction and perception showed an association with weight status. More overweight or obese children indicated dissatisfaction or underestimation of body image than normal-weight children. Children with body image dissatisfaction due to heavier perceived body size than ideal body image showed lower frequencies of consumption of meals and vegetables, compared to those who were satisfied with their body image. Children who underestimated their body image were more likely to have a lower frequency of breakfast and meal regularity and a higher frequency of eating out of home or food deliveries than those with accurate body image perception. In addition, body image underestimation showed an association with lower intakes of protein, dietary fiber and calcium, and the higher percentage of calories derived from fat. Conclusion: Body image dissatisfaction as well as underestimation in children before puberty showed an association with overweight or obesity, and was also related to unhealthy dietary habits. These findings highlight the importance of accurate perception and satisfaction with body image in preadolescent children in order to prevent development of obesity in adolescents and adults.

BACKGROUND/OBJECTIVES: College students are in transition from adolescence to adulthood, and it has been reported that they show poor dietary habits. This study was conducted to compare body image perception, nutrition knowledge, dietary attitudes, dietary habits, and health-related lifestyles between Korean college students (KCS) and Mongolian college students (MCS). SUBJECTS/METHODS: Subjects were 314 KCS and 280 MCS. The data includes results of self-administered questionnaires; statistical analysis was performed using the SPSS 23.0 program. RESULTS: With regards to body image perception, KCS perceived themselves to be fatter on current body image than ideal body image compared to MCS; 64.0% of KCS and 34.6% of MCS desired to be thinner. Total score of nutrition knowledge in KCS (17.0) was significantly higher compared to MCS (8.4) (P < 0.001), but total score of dietary attitudes in KCS (27.0) was significantly lower compared to MCS (31.2) (P < 0.001). Nutrition knowledge had a significantly positive correlation with dietary attitudes in MCS (P < 0.01). Meal consumption among male and female subjects was 2 and 3 times, respectively, in order in KCS, and 3 and 2 times, respectively, in order in MCS (P < 0.001). Rate of skipping breakfast in both genders was significantly higher in KCS than in MCS (male: P < 0.05, female: P < 0.001). In health-related lifestyles, KCS had a significantly higher rate in frequency of alcohol drinking (P < 0.001), exercise (P < 0.01), and mobile phone usage (P < 0.001), compared to MCS. CONCLUSIONS: This study suggests that development of nutrition education program which is effective and proper is required to improve healthy dietary habits among college students of both countries. Essential contents should include acquirement of nutrition knowledge and a motivation for its application to actual life for KCS, and improvement of healthy dietary habits for MCS.

The widespread pursuit of a thin physique may have a detrimental impact on the wellbeing of preadolescents. The influence of body image distortions on the lifestyles, dieting behaviors, and psychological factors was investigated in 631 fifth and sixth grade children in Kyeonggi-do, Korea. Children were classified into three weight groups (underweight, normal, and overweight) and three perception groups (underestimation, normal, and overestimation). Necessary information was obtained by questionnaire, and each subject's weight status was determined by the Rohrer index calculated from the annual measurement records, which were obtained from the school. According to their current weights, 57.4% of children were normal and 32.2% were overweight or obese, 16.6% of the children overestimated their body weight, and 55.2% had an undistorted body image. Overweight children had desirable lifestyles and dietary habits and presented reasonable weight control behaviors. Compared to those without distortion, the overestimated group had greater interest in weight control ($P$ = 0.003) and dissatisfaction with their body weights ($P$ = 0.011), presented unhealthy reasons to lose weight ($P$ = 0.026), and had higher scores for "feeling sad when comparing own body with others" ($P$ = 0.000) and for "easily getting annoyed and tired" ($P$ = 0.037), even though they had similar obesity indices. More subjects from the overestimation group ($P$ = 0.006) chose drama/movies as their favorite TV programs, suggesting a possible role for the media in body image distortion. These findings suggest that body image distortion can lead preadolescents to develop stress about obesity and unhealthy dieting practices, despite similar obesity indices to those without distorted body images. These results emphasize the importance of having an undistorted body image.
