This study compared the nutritional quality of Korean adults's consumption of lunch prepared at home, commercial places, and institutions. The one day food intake data collected via 24-hour recall in the 2001 National Health and Nutrition Survey were analyzed. Individuals with 19-64 years of age were selected (n = 5,756). Sampling weights in the Survey were used to generate nationally representative estimates. Lunch was categorized into three groups according to the place where the lunch was prepared. home, commercial places, and institutions such as schools and work places. Comparison among the three groups was made for 19-39 years old men (n = 1,387) and women (n =1,572) and 40-64 years old men (n = 1,364) and women (1,433), respectively. The lunch prepared away from home contained more calories. The lunch prepared commercially was higher in calories percentages from fat than that prepared either at home or at institutions. Across the age and gender groups, lunch prepared at home contribute a high level of sodium intake. Among individuals with 40-64 years of age, but not those with 19-39 years of age, lunch prepared commercially was as sodium dense as that prepared at home. Among individuals with 19-39 years of age, the sodium density of lunch prepared commercially was about the same as that prepared at institutional food service of which the menus were planned by dieticians. Such differences in nutritional quality among meals prepared at home, commercial places, and institutions should be considered and applied for the content development of nutrition education and policy.

Purpose: To analyze the growth response to growth hormone (GH) therapy in prepubertal patients with Noonan syndrome (NS) harboring different genetic mutations. Methods: Twenty-three patients with prepubertal NS treated at Pusan National University Children's Hospital between March 2009 and July 2017 were enrolled. According to the disease-causing genes identified, the patients with NS were divided into 4 groups. Three groups were positive for mutations of the PTPN11, RAF1, and SOS1 genes. The five genes undetected (FGU) group was negative for PTPN11, RAF1, SOS1, KRAS, and BRAF gene mutations. The influence of genotype was retrospectively analyzed by comparing the growth parameters after GH therapy. Results: The mean chronological age at the start of GH treatment was $5.85{\pm}2.67years$. At the beginning of the GH treatment, the height standard deviation score (SDS), growth velocity (GV), and lower levels of insulin-like growth factor-1 (IGF)-1 levels were not statistically different among the groups. All the 23 NS patients had significantly increased height SDS and serum IGF-1 level during the 3 years of treatment. GV was highest during the first year of treatment. During the 3 years of GH therapy, the PTPN11, RAF1, and SOS1 groups showed less improvement in height SDS, IGF-1 SDS, and GV, and less increase in bone age-to-chronological age ratio than the FGU group. Conclusion: The 3-year GH therapy in the 23 prepubertal patients with NS was effective in improving height SDS, GV, and serum IGF-1 levels. The FGU group showed a better response to recombinant human GH therapy than the PTPN11, RAF1, and SOS1 groups.

Plasma levels of lipoproteins were observed in vegetarians and non-vegetarians in order to compare the values between the two groups with different dietary habits, and among different age groups. All 162 vegetarians and 95 non-vegetarians were selected for this study. In detail, male vegetarians subjects were devided into three groups according to their ages, 20's, 30's and 40's. And three control groups were also selected at matching basis. Two groups each were selected for female subjects in their 20's and 40's. All ten groups were adopted and the lipids levels were compared appropriately. Plasma $pre-{\beta}-lipoprotein$ levels of vegetarians and non-vegetarians were not significantly in all groups. And plama ${\alpha}-lipporoten$ levels of non-vegetarians were higher than the ones for vegetarians as compared with male of 20's, male 30's and female of 40's, and it was not significantly as compared with female of 20's. And plasma ${\beta}-lipoprotein$ levels of vegetarians were significantly lower than the ones for non-vegetarians in all groups. Most of plasma lipoprotein levels measured were found to be lower in vegetarians and tended to be higher age groups of both vegetarians and non-vegetarians. And plasma ${\alpha}-lipoprotein$ levels which is known to be adversely related to atheroscherosis were higher in non-vegetarians, it can be concluded in this study that the plasma lipoprotein levels of non-vegetarians under Korea dietary patterns are quite acceptable.

In this study, foot shapes were compared between the men in their 20's and 60's, with the application of 3-dimensional measurement data, and the classification was established in consideration of each of their features. The results are as follows: 1. The investigation into the differences between the groups for the 3-dimensional measurement items of the men in their 20's and 60's indicated that those in their 20's had larger values than those in the 60's age group for all of the length items, while those in the 60's age group had larger values for all of the angle items. 2. The analysis of the constituting factors for the feet of those in their 60's and 20's resulted in the 7 items for the 20's age group and 8 items for those in the 60's age group. 3. The comparison of foot classifications for the 60's age group and 20's age group presented 3 types each for both groups, but the features of each type was different. To examine each characteristic by each type and age group, following can be determined of the 60's age group. Type 1 had a thick instep, high malleolus position and heel and a thick formed ankle. Type 2 the entire foot was small, and the big toe was formed in such a way that it tened to bend toward the inside. When the whole size compared with similar Type 1, Type 3 had a low instep, a low heel, the big toe did not bend and ankle form was thin. The following can be determined of the 20's age group. Type 1 had narrow width a thin ankle and the big toe was formed in such a way that it bended toward the inside. Compared with length, Type 2 had wide width and a thick ankle. Type 3 had a larger overall size, thick instep and wide and the toe was big, but the characteristic of inside and outside of a malleolus position was low and the big toe's form showed no tendencies to bend.

Automatic age estimation has been used in many social network applications, practical commercial applications, and human-computer interaction visual-surveillance biometrics. However, it has rarely been explored. In this paper, we propose an automatic age estimation system, which includes face detection and convolutional deep learning based on an inception module. The latter is a 22-layer-deep network that serves as the particular category of the inception design. To evaluate the proposed approach, we use 4,000 images of eight different age groups from the Adience age dataset. k-fold cross-validation (k = 5) is applied. A comparison of the performance of the proposed work and recent related methods is presented. The results show that the proposed method significantly outperforms existing methods in terms of the exact accuracy and off-by-one accuracy. The off-by-one accuracy is when the result is off by one adjacent age label to the above or below. For the exact accuracy, the age label of "60+" is classified with the highest accuracy of 76%.

Purpose: This study examines and compares the differences between self-esteem and health promotion behavior of health department and non-health department college students. Method: The research instruments were as follows : The first one is RSES developed by Rosenberg and translated into Korean by Jeon. The second one is HPLP developed by Walker et al, and including six subareas by Lee and modified to be suitable to Korean culture by Suh. Data were statistically analyzed with SPSS PC/12.0. Results : 1. Comparison of self-esteem had no significant difference(p=.190) and health promotion behaviors had significant differences(p=.000) between the two groups. 2. According to general characteristics and health-related characteristics, the differences of self-esteem in health department showed significant differences in grade(p=.020), sex(p=.000), age(p=.000), parents' economic conditions(p=.048), and smoking(p=.030) while non-health departments revealed significant differences in grade(p=.003), sex(p=.000), age(p=.000) and smoking(p=.001). 3. According to general characteristics and health-related characteristics, the differences of health promotion behaviors in health department showed significant differences in grade(p=.008), sex(p=.021), age(p=.000) and parents' economic conditions(p=.017) while non-health department revealed significant differences in sex(p=.000) and age(p=.000). 4. There were positive correlations between self-esteem, health promotion behaviors and subareas in health department (r=.422) and non-health department (r=.383). Conclusion: There were significant positive correlations between self-esteem and health promotion behaviors in health and non-health department college students. Therefore, health related programs should be developed to enhance self-esteem and health management by college students can influence themselves on self-esteem and health promotion behaviors.

The purpose of the present study was to use digital profile image features and digital image analysis of fixed-dimension bone regions, extracted from standardized periapical radiographs of the maxilla, to determine whether differences exist in alveolar bone of younger women(mean age: 59.23±7.34 years) and just menopaused women(mean age: 59.23±7.34). Periapical films were used from two groups of 20 randomly selected women. None of the subjects had a remarkable medical history. To simplify protocol, we chose one interproximal bone area between the maxillary right canine and lateral incisor for study. Ech film was digitized into a 1312 x 1024 pixel x 8 bit depth matrix by means of a Nikon 35 mm film scanner(LS-35lOAF, Japan) with fixed gain and internal dark current correction to maintain constant illumination. The scanner was interfaced to a Macintosh LC III computer(Apple Computer, Charlotte, N.C.). Area and profile orientation were selected with a NIMH Image 1.37(NIH Research Services Branch, Bethesda, Md.). Histogram features were extracted from each profile and area. The results of this study indicate that mean pixel intensities didn't differ significantly between two groups and there was a high correlarion-coefficient between digitized radiographic profile features and area features.
