The volume perception of water according to cup shape was examined in female college students divided into a normal weight group (<23 body mass index, n=51) and an overweight group (${\geq}$23 body mass index, n=48). The perceived water volume was recorded by participants after they observed the water volume in cups with different shape (highball and tumbler) and with different base height (high base and low base), which contained the same amount of water (150 ml). The normal weight group perceived a water volume of 238.5 ml (highball) and 201.6 ml (tumbler) for the high base cups. The overweight group perceived a volume of 245.6 ml (highball) and 188.8 ml (tumbler). For the low base cups, the normal weight group perceived a water volume of 207.8 ml (highball) and 104.1 ml (tumbler). The overweight group perceived a volume of 202.2 ml (highball) and 100.4 ml (tumbler). Both the normal weight and overweight groups perceived significantly more liquid in the highball cups compared to the tumbler cups. In addition, both groups perceived significantly more liquid in the high base cups compared to the low base cups. However, there were no significant differences in the estimated variance of perceived volume between the normal weight and overweight groups according to the cup shape and cup base height. In conclusion, cup shape and base height potentially affects volume perception. Therefore, modifying cup shape may be used in a weight control program to help control caloric beverage consumption.

BACKGROUND/OBJECTIVES: Studies have indicated that university students majoring in nutrition and dietetics or sport sciences may have more obsessions associated with eating attitudes and body shape perception compared to other disciplines i.e. social sciences. Therefore, this study aimed to assess and compare the risk of eating disorders and body shape perception. MATERIALS/METHODS: Data was collected from 773 undergraduate students at the Departments of Nutrition and Dietetics (NDD) (n = 254), Physical Education and Sports (PESD) (n = 263), and Social Sciences (SOC) (n = 256).A socio-demographic and personal information questionnaire, Eating Attitudes Test (EAT-40), Body Shape Questionnaire (BSQ-34), Perceived Figure Rating Scale (FRS) were applied; and body weights and heights were measured. RESULTS: Mean EAT-40 scores showed that, both male and female students of PESD had the highest scores ($7.4{\pm}11.6$) compared with NDD ($14.3{\pm}8.3$) and SOC ($13.0{\pm}6.2$) (P < 0.05). According to EAT-40 classification, high risk in abnormal eating behavior was more in PESD (10.7%) compared to NDD (2.9%) and SOC (0.4%) students (P < 0.05). Students of PESD, who skipped meal, had higher tendency to the risk of eating disorders (P < 0.05). In parallel, body shape perception was found to be marked with higher scores in NDD ($72.0{\pm}28.7$) and PESD ($71.5{\pm}32.8$) compared with SOC ($64.2{\pm}27.5$) students (P < 0.05). Considering BSQ-34 classification, high concern (moderate and marked) for body shape were more in PESD (7.4 %) compared to NDD (5.2%) and SOC (1.9%) students (P < 0.05). The body size judgement via obtained by the FRS scale were generally correlated with BMI. The Body Mass Index levels were in normal range (Mean BMI: $21.9{\pm}2.8kg/m^2$) and generally consistent with FRS data. CONCLUSIONS: Tendency to the abnormal eating behavior and substantial body shape perception were higher in PESD students who have more concern on body shape and were not well-educated about nutrition. In conclusion, substantial concern on physical appearance might affect eating behavior disorders in PESD students.

수많은 공간지각 연구 결과, Euclidean 3-D 구조는 양안 입체시, 움직임, 입체시와 움직임의 결합, 또는 여러 광학 정보의 결합으로도 복구될 수 없다는 사실이 밝혀졌다. 그러나 인간은 이러한 부정확한 공간지각에도 불구하고 특정 과제를 수행하는 데는 어려움이 전혀 없다. 우리는 인공지능과 컴퓨터 비전에 인간의 기술과 능력을 적용해 왔지만 이러한 기계들은 여전히 인간의 능력보다 훨씬 뒤떨어져 있다. 따라서 우리는 인간이 공간의 깊이를 어떻게 지각하는지, 과제를 수행하기 위해 어떠한 정보들을 사용하여 3차원 공간을 정확하게 지각하는지 이해해야 한다. 이 논문의 목적은 미래에 더욱 발전된 인공지능 로봇에 인간의 능력을 적용하기 위해 공간지각 문헌을 검토하는 것이다.

Purpose: The purpose of this study was to explore the correlates of maternal perception (identification and satisfaction) of children's weight, maternal body shape satisfaction, and maternal feeding styles in Korean preschool-aged children. Methods: A cross-sectional survey design was utilized. Participants consisted of 287 pairs of preschool-aged children (3-6 years) and their mothers. Data were analyzed by ${\chi}^2$-test, Fisher's exact test, ANOVA, and the Pearson correlation coefficient. Results: Among the 287 mothers, 47.7% underestimated their children's weight, while 15.7% overestimated it. 46.7% of the mothers wished their children weighed more, while 11.1% of them wished their children weighed less. The mean score of maternal body shape satisfaction was $83.75{\pm}28.77$. The mean score of parent-centered feeding styles was $2.95{\pm}0.54$, and the mean score of child-centered feeding styles was $3.33{\pm}0.42$. There were statistically significant correlations between maternal identification of children's weight and children's body mass index (BMI) (r=-.366, p<.001). In addition, there were statistically significant correlations between maternal satisfaction of children's weight and children's BMI (r=-.484, p<.001), maternal BMI (r=-.126, p=.033), and maternal body shape satisfaction (r=-.127, p=.031). Conclusion: The results of the study suggest that intervention programs for mothers to develop more accurate perception of their child's weight should be established.

Objectives: This study was conducted to examine the relationships among body image, self-esteem and sociability according to perception of body shape and obesity level. Methods: The subjects in this study were 325 elementary school youngsters in their sixth year. A survey was conducted, and one-way ANOVA, Scheffe test, Pearson's correlation analysis and path analysis were used for data analysis. Results: Normal weight group accounted for 43.4%, under weight group 34.8% and obesity group 21.8%. In underweight group, 53.1% of the subjects perceived their body was normal or fatty while 17% of subjects in normal group perceived their body was fatty. There were significant differences in body image according to the perception of body shape by grade(F=15.90, p=.000) and to the level of obesity(F=6.18, p=.002). There was a significant difference in self-esteem according to the perception of body shape by grade(F=3.17, p=.430). There was a significant difference in sociability according to the level of obesity(F=3.48, p=.032). There was significantly strong positive correlation among their body image, self-esteem and sociability. A structural equation model was tested and fitted the data well. Conclusions: This study suggested that health education is needed to establish the correct body image from the elementary school periods by school health educators. The right body image is more important than anything else to improve self-esteem and sociability.

최근 컴퓨터 그래픽스와 사용자의 인지를 결합한 다양한 연구들이 진행되고 있다. Cole 등은 미술가들의 라인 드로잉 데이터를 수집하여 기존의 CG(Computer-Generated) 라인 드로잉 알고리즘들이 미술가들의 드로잉 특성을 반영하고 있는지 비교하고, 사용자들이 어떤 라인 드로잉 알고리즘의 결과에서 형태를 효과적으로 인지하는지 평가하는 실험을 수행하였다. 그러나 라인 드로잉 알고리즘의 결과보다 BRDF 쉐이딩 모델이 적용된 결과에서 형태를 더욱 효과적으로 인지한다는 결과를 보였는데, 이는 음영이 형태 정보를 전단하기에 더욱 효과적인 요소임을 반증한다. 따라서 본 논문에서는 물체에서 인지한 음영과 미술가들의 음영 표현, 그리고 CG 쉐이딩 알고리즘 간의 상관관계에 대해서 연구한다. 특히, 미술가들의 음영 표현 특성과 CG 쉐이딩 알고리즘에서 나타나는 특성에 초점을 맞추고 이를 정량적으로 분석한다. 본 논문에서 수집한 실험 데이터 및 분석 결과는 효과적인 형태 전달을 목적으로 하는 새로운 CG 쉐이딩 알고리즘을 설계하는데 활용한 것으로 기대된다.

The purpose of this study is to examine American students' perceptions of contemporary fashion design that incorporates Korean traditional costume. The findings, which are based on a survey of American students' aesthetic response to the fashion designs, are as follows. First, the impressions of American students about the fashion designs were affected by two major factors, Tradition and Trend. The Tradition factor was related to the impressions traditional, formal, elegant, classic, romantic, gorgeous, and natural, but was correlated negatively to the impressions dynamic, modern, and casual. The Trend factor was related to the impressions chic, trendy, and clear but not dandy. Designs with elongated shape had a positive score for the Tradition factor and designs with curvy line had a positive score for the Trend factor. Second, American students gave visual priority to the aspects of shape such as garment type and silhouette when they evaluated the designs. Color was less important than the aspect of shape in their fashion image perception. Therefore, they categorized the designs by similarity of garment types, and then sub-categorized them by color. The meaning of Korean traditional motifs or details was not significant to American students. Third, American students showed the tendency that the more they evaluated the designs to be gorgeous or trendy, the more they liked the designs. Furthermore, they liked the designs which have a positive score for the Trend factor.

The purpose of this study is to provide a basic data of clothing development which can improve the satisfaction of the body shape by examining the subjective evaluation and type characteristics of the old-old women themselves. Q methodology was used for the study of subjectivity. The types of the body shape of the old-old women were analyzed as five types: bent body with protruding abdomen, backward bent body with slender legs, inverted triangle, swollen cylinder, triangle. The bent body with protruding abdomen had a bent back and waist. They were recognized that the bust and shoulders were sagging and abdomen was protruding. The backward bent body with slender legs was the smallest of the five types with a BMI index and shoulders and bust were sagging. And knee and waist were bent and legs were thin. The inverted triangular shape showed the highest BMI index among the 5 types, indicating that it is obese. They thought that the upper body was developed and the lower body and legs were slender. The swollen cylinder shape was analyzed to be the smallest and the most fat body. The triangle shape had developed lower body and bent back and waist. It is considered that a design consideration is needed to cover the disadvantages of the body shape in consideration of not only wearing feeling but also aesthetic part when making clothes. By making ergonomic garments considering the characteristics of body shape, it can be expected to change the body shape due to the wearing of clothing that is not suitable for body shape and the effect on physical health in a positive direction.
