In a previous study, a dietary supplement was developed in our lab using natural herbal extracts against digest enzyme activity in GI tract for weight control. This natural herbal extracts could regulate absorption of glucose and lipid by the inhibition of digest enzyme activity. In this study, we screened the natural herbs that inhibit glucoamylase activity and developed an water extract of cinnamon. The cinnamon extract delayed and decreased the increment of carbohydrate degradation through the inhibition of glucoamylase activity in vitro. Fifty volunteers were subjected to the intake of the herbal extracts by taking twice a day for 60 days. As a result, the treated subjects lost 3 kg of body weight and 3.5 kg of body fat mass after the treatment. Furthermore, the body mass index and waist size were significantly decreased during the experimental period. Above results suggested that the administration of the dietary additives composed of cinnamon and natural herbal extract improves the obesity by the decrement of body weight and body fat mass.

Djungarian hamsters show distinct seasonal rhythms in several physiological parameters. One of them is daily torpor that occurs in winter with decreased body temperature (about 1O-20$^{\circ}$C) during daytime. Daily torpor is induced by short-day photoperiod, food restriction and castration. But the mechanism to induce daily torpor has not been clarified. In the present study, we tried to clarify the process of daily torpor induction in detail. Adult male hamsters were kept in long photoperiod and high temperature (LP-HT) before the experiment and, thereafter, the animals were transferred to short photoperiod and low temperature (SP-LT), and they were kept in this condition for about six months. The daily rhythms of locomotor activity and body temperature were recorded every three-minutes by using the Minimitter telemetry system. Locomotor activity and body temperature showed very closely synchronized rhythms. All animals under LP-HT showed daily rhythms with higher locomotor activity and body temperature in nighttime than in daytime. Under SP-LT, there were two types of animals with and without showing daily torpor. Thus, they have individual differences in the response to SP -LT.

The purpose of this study was to find out differences of visual evaluation according to perceiver's gender, clothing silhouette, and body exposure of the lingerie look. Subjects were 246 college males and females in Seoul. The visual evaluation of the lingerie look was divided into four image dimensions: elegance, individuality, fascination, and activity. Silhouette had significant influences on the perception of elegance and activity. The hourglass silhouettes were evaluated more elegant and active than the tubular silhouettes. The body exposure had significant influences on the evaluation of elegance, individuality, fascination, and activity. The shoulder and the back exposure were estimated high in fascination, the breast exposure low in elegance, and the waist exposure high in individuality and activity. Individuality, fascination, and activity had interaction effects by perceiver's gender and body exposure. Males estimated the waist exposure to be more fascinating than females, and females estimated the breast exposure to be less active than males. There were significant interaction effects in evaluating the 4 image dimensions according to the silhouette and body exposure. The shoulder and the leg exposure of the hourglass silhouettes were estimated more elegant than those of the tubular silhouettes. Dimensions of clothing image which influenced on preference of lingerie look were different between males and females.

The objectives of this study were to classify the contents of lifestyle of adolescents, to investigate the relationships between lifestyles and appearance behavior, and to examine how appearance behavior was influenced by lifestyles and demographic variables of male and female adolescents. The method of the study was survey research by using questionnaires. Subjects were 414 high school students in Seoul: 176 were males and 238 females. Five dimensions of lifestyles were derived by factor analysis: ‘digital orientation', 'positive activity', 'achievement orientation', 'material orientation', and ‘frugality'. Digital orientation had, in case of the male, a positive relation with body-modification need, a positive one with appearance interest in female. Positive activity had positive relations with appearance interest and body satisfaction in both male and female. Appearance interest, weight interest, and body-modification need levels were significantly higher for female than for male, whereas body satisfaction were higher for male than for female. Appearance interest of male was influenced by positive activities and social stratification. Appearance interest of female was influenced by material orientation and positive activity. Body-modification need of male was influenced by digital orientation and frugality(-), that of female only influenced by material orientation. Fashion and brand preference of male was influenced by material orientation, frugality(-), and social stratification. In case of the female, fashion was influenced by positive activity, material orientation and frugality(-), brand preference influenced by material orientation and positive activity.

To compare of body composition and backmusclestrength between physical activity group (PAG) and non-physical activity group (Non-PAG). From Jun 14 to July 13 2018, 66 students were divided into PAG (male 20, female 13) and Non-PAG (male 18, female 15) from questionnaires for general characteristics and activity. All participants were measured body composition (Inbody 720, Biospace, Korea) and backmusclestrength (T.K.K. 5402, TAKEI, Japan) after obtaining written informed consent. Statistical analysis was performed by independent t-test and cross-sectional test using SPSS ver. 19.0 (USA). Sex and body mass index were not significant difference between two groups. Exercise was significant difference between PAG and Non-PAG(100% vs. 45.5%, p<0.001), especially running and push-up, sit-up(p<0.001). Body composition was no significant difference between PAG and Non-PAG (p>0.05). Backmusclestrength was significantly higher in PAG than that in N on-PAG (p<0.01). It is suggested that exercise affects to Backmusclestrength.

Social media is an essential part of everyday life in modern society and plays an important role in communicating the ideal body image. With the increased prevalence and high popularity of social media, the problems associated with the addictive use of social media have become a social issue. Utilizing social comparison theory, this study examined (1) the effect of appearance related photo activities on body satisfaction through appearance comparison and (2) the moderating effect of Instagram addiction in relationships among appearance related photo activity, appearance comparison, and body satisfaction. We tested the proposed relationships between research variables using multi-group structural equation modeling analysis on a sample of 346 young female Instagram users. The sample was divided into two groups of high and low addicted Instagram users. The results of this study showed that the appearance related photo activity positively influenced appearance comparison for both high and low addiction groups. For the high addiction group, the effect of appearance comparison on body satisfaction was not statistically significant; however, this relationship was significant and negative for the low addiction group. A significant moderating effect of Instagram addiction was found in the relationship between appearance related photo activity and appearance comparison.

Video-based human-activity recognition has become increasingly popular due to the prominent corresponding applications in a variety of fields such as computer vision, image processing, smart-home healthcare, and human-computer interactions. The essential goals of a video-based activity-recognition system include the provision of behavior-based information to enable functionality that proactively assists a person with his/her tasks. The target of this work is the development of a novel approach for human-activity recognition, whereby human-body-joint features that are extracted from depth videos are used. From silhouette images taken at every depth, the direction and magnitude features are first obtained from each connected body-joint pair so that they can be augmented later with motion direction, as well as with the magnitude features of each joint in the next frame. A generalized discriminant analysis (GDA) is applied to make the spatiotemporal features more robust, followed by the feeding of the time-sequence features into a Hidden Markov Model (HMM) for the training of each activity. Lastly, all of the trained-activity HMMs are used for depth-video activity recognition.
