  • Aged garlic extract (AGE) is known to have a protective effect against immune system, endothelial function, oxidative stress and inflammation. We examined the effects of exercise with and without aged garlic extract administration on body weight, lipid profiles, inflammatory cytokines, and oxidative stress marker in high-fat diet (HFD)-induced obese rats. Forty-five Sprague-Dawley rats were fed either a HFD (HFD, n = 40) or a normal diet (ND, n = 5) for 6 weeks and thereafter randomized into ND (n = 5), HFD (n = 10), HFD with AGE (n = 10), HFD with Exercise (n = 10), or HFD with Exercise+AGE (n = 10) for 4 weeks. AGE groups were administered at a dose of 2.86 g/kg body weight, orally. Exercise consisted of running 15-60 min 5 days/week with gradually increasing intensity. AGE (P<0.01), Exercise, and Exercise+AGE (P<0.001) attenuated body weight gain and food efficiency ratio compared to HFD. Visceral fat and liver weight gain were attenuated (P<0.05) with all three interventions with a greater effect on visceral fat in the Exercise+AGE than AGE (P<0.001). In reducing visceral fat (P<0.001), epididymal fat (P<0.01) and liver weight (P<0.001), Exercise+AGE was effective, but exercise showed a stronger suppressive effect than AGE. Exercise+AGE showed further additive effects on reducing visceral fat and liver weight (P<0.001). AGE significantly attenuated the increase in total cholesterol and low-density lipoprotein-cholesterol compared with HFD (P<0.05). Exercise+AGE attenuated the increase in triglycerides compared with HFD (P<0.05). Exercise group significantly decrease in C-reactive protein (P<0.001). These results suggest that AGE supplementation and exercise alone have anti-obesity, cholesterol lowering, and anti-inflammatory effects, but the combined intervention is more effective in reducing weight gain and triglycerides levels than either intervention alone.

  • BACKGROUND/OBJECTIVES: This study aimed to establish a mother and child cohort in the Chinese population, and investigate human breastmilk (HBM) composition and its relationship with maternal body mass index (BMI) and infant growth during the first 3 mon of life. SUBJECTS/METHODS: A total of 101 Chinese mother and infant pairs were included in this prospective cohort. Alterations in the milk macronutrients of Chinese mothers at 1 mon (T1), 2 mon (T2), and 3 mon (T3) lactation were analyzed. HBM fatty acid (FA) profiles were measured by gas chromatography (GC), and HBM proteomic profiling was achieved by matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS). RESULTS: During the first 3 mon of lactation (P < 0.05), significant decreases were determined in the levels of total energy, fat, protein, and osteopontin (OPN), as well as ratios of long-chain saturated FA (including C16:0, C22:0 and C24:0), monounsaturated FA (including C16:1), and n-6 poly unsaturated FA (PUFA) (including C20:3n-6 and C20:4n-6, and n-6/n-3). Conversely, butyrate, C6:0 and n-3 PUFA C18:3n-3 (α-linolenic acid, ALA) were significantly increased during the first 3 mon (P < 0.05). HBM proteomic analyses distinguished compositional protein differences over time (P = 0.001). Personalized motherinfant analyses demonstrated that HBM from high BMI mothers presented increased total energy, fat, protein and OPN, and increased content of n-6 PUFA (including C18:3n-6, C20:3n-6 and n-6/n-3 ratio) as compared with low BMI mothers (P < 0.05). Furthermore, BMI of the mothers positively correlated with the head circumference (HC) of infants as well as the specific n-6 PUFA C20:3n-6 over the 3 time points examined. Infant HC was negatively associated with C18:0. CONCLUSION: This study provides additional evidence to the Chinese HBM database, and further knowledge of FA function. It also helps to establish future maternal strategies that support the healthy growth and development of Chinese infants.

  • The number of CT scans is increasing every year due to the improvement of the medical standards of the public, and thus the annual dose of medical radiation is also increasing. In this study, we evaluated the effective dose of the human body exposed to CT scans and estimated LAR. First, five region were selected from the CT diagnostic reference level guideline, and the effective dose of human body exposed to each examination was evaluated by clinical CT device. Second, the human organs and effective dose were calculated using the ALARA-CT program under the same conditions. Third, lifetime attributable risk (LAR) estimated by the effective dose exposed through the previous CT scan was estimated. As a result, the most effective dose was 21.18 mSv during the abdomen 4 phase scan, and the dose level was below DRL for all other tests except for the abdominal examination. As a result of evaluating effective dose using a dose calculation program under the same conditions, the results showed about 1.1 to 1.9 times higher results for each examination. In the case of organ dose, the closer the organ to the scan site, the higher the scattering ray. The lifetime attributable risk to CT radiation dose in adults was gradually decreased with age, and the results were somewhat different according to gender.

  • Background: New beauty soaps are always subject to evaluation. Purposes: This study performed a human application test and safety evaluation on the cleaning effect of the fine dust mimic of the test product, Daziwar soap bar, on 52 women. Methods: The quantitative change measured the cleaning effect of fine dust before and after washing immediately after spraying the fine mimetic dust on the forearm of 22 women. In addition, the safety was evaluated at 30 minutes, 24 hours, and 48 hours after 24 hours after applying the patch to the woman's back. Results: After one time washing with the soap immediately after spraying dust on the inside of the arm, the amount of the remaining mimetic was statistically significantly decreased in both the test group and the control group (p < .001). However, the washing rate was 99.96% in the experimental group and 75.58% in the control group. The questionnaire was evaluated as 'Good' or higher in terms of efficacy. In the evaluating of adverse reactions after washing fine dust by a dermatologist, there were no reports or observations of specific skin adverse reactions or abnormal findings in the subjects. The safety evaluation was judged as non-irritating in the skin reaction evaluation at 30 minutes, 24 hours, and 48 hours after instillation on the back for 24 hours. Conclusions: The test product, Daziwar soap, was found to be very helpful in cleaning fine dust on the human body and was found to be safe for the human body.

  • This study aims at developing ergonomics patterns for the sleeve of structural firefighting protective clothing through 3D motion analysis in order to ensure efficiency and safety of firefighters who are exposed to harmful environment at work. A new research pattern was developed by applying the total results of 3D motion analysis, changes of body surface length measurements, and 2D data on 3D body shape analysis on the size 3 patterns of the existing coat sleeve. For the sleeves, we used the body surface length of the range of shoulder's flexion and the joint angle of the range of wrist's ulnar deviation. And for the production of structural firefighting protective clothing using the research pattern, we recruited a recognized producer of structural firefighting protective clothing designated by KFI. Unlike everyday clothes, structural firefighting protective clothing should be able to fully protect the wearers from the harmful environment that threatens their lives and should not cause any restrictions on their movement. Therefore, the focus of research and development of such protective clothing should be placed on consistent development of new technologies and production methods that will provide protection and comfort for the wearer rather than production cost reduction or operational efficiency. This study is meaningful as it applied 3D motion analysis instead of the existing methods to develop the patterns. In particular, since 3D motion analysis enables the measurement of the range of motion, there should be continuous research on the development of ergonomics patterns that consider workers' range of motion.

  • In this study, we used the 3D simulation program to create bodice patterns for adolescents boy students and analyze the fitting and air gap through 3D simulation. The purpose of this study was to select the bodice pattern method that best suited the body shapes of the adolescents male students. The subjects of this study were the French E pattern, Japanese N pattern, and Korean industrial L and J patterns. The applied size was the sixth Korean human body size survey data of 2010 Korea. The age range of the subjects was 13-18 years. DC Suite Program Ver. 5.1 was used, and SPSS 23.0 program was used for data analysis. As a result of comparing the shapes of the bodice patterns in the 3D simulation program, the E pattern had two waist darts on the front and one shoulder dart and one waist dart on the back, and the J and L patterns only had one dart on the back. The N pattern had no darts on either the front or back. As a result of examining the appearance evaluation of the pattern, air gap, color distribution, and clothing cross-section, the E pattern was evaluated as the closest to the body, and the N pattern was evaluated as the pattern with the largest allowance. The J pattern was evaluated as the best fit for body shape of the male adolescents. However, it is necessary to develop a pattern system by adding extra ease in setting the center front length.

  • It is widely recognized that for 3D human pose estimation (HPE), dataset acquisition is expensive and the effectiveness of augmentation techniques of conventional visual recognition tasks is limited. We address these difficulties by presenting a simple but effective method that augments input images in terms of viewpoints when training a 3D human pose estimation (HPE) model. Our intuition is that meaningful variants of the input images for HPE could be obtained by viewing a human instance in the images from an arbitrary viewpoint different from that in the original images. The core idea is to synthesize new images that have self-occlusion and thus are difficult to predict at different viewpoints even with the same pose of the original example. We incorporate this idea into the training procedure of the 3D HPE model as an augmentation stage of the input samples. We show that a strategy for augmenting the synthesized example should be carefully designed in terms of the frequency of performing the augmentation and the selection of viewpoints for synthesizing the samples. To this end, we propose a new metric to measure the prediction difficulty of input images for 3D HPE in terms of the distance between corresponding keypoints on both sides of a human body. Extensive exploration of the space of augmentation probability choices and example selection according to the proposed distance metric leads to a performance gain of up to 6.2% on Human3.6M, the well-known pose estimation dataset.

  • This paper presents the analysis of tactile effects on different body parts according to the various vibration patterns. The experiments use a vibration pad made of 16 vibration elements in the form of $4{\times}4$ array. The vibration elements are controlled by a 8-bit microprocessor. The sound of gunshot initiates a vibration pattern on different body parts and its sensitivity is measured. The analysis of the experiments lead us to conclude that the vibration pad is the most realistic interface for shooting games and the shoulder part is the most sensitive part in the body. In addition, the most effective vibration pattern is the for the pattern which gives the sensation of spreading out from the center to the outside. This study analyzes the relationship between the human body parts and the tactile sensations by the various vibration patterns. The result of this study will be a good reference for user studies in the field of haptics based on the vibration.

  • Purpose: The unique nutrient requirements of premature infants necessitate knowledge of the composition of human milk produced by mothers of such infants. We investigated longitudinal changes in iron concentration of preterm human milk and compared to those observed in human milk of mothers of 1-week old term infants to determine optimal iron supplementation guidelines when preterm infants are nourished exclusively by breast feeding. Methods: Human milk samples were collected at 1, 2, 4, 6, 8 and 12 weeks postpartum from 103 mothers who delivered infants of gestational age <34 weeks or weighing <1,800 g. Term human milk samples were collected at 1 week postpartum from 24 mothers. Results: There were no significant differences in the iron concentrations of preterm human milk obtained at 2 to 8 weeks postpartum (36.3${\pm}$23.1 to 45.8${\pm}$26.0 $\mu$g/dL), but these concentrations were higher than those noted at 1 week in preterm (23.1${\pm}$14.6 $\mu$g/ dL) and term (25.2${\pm}$7.55 $\mu$g/dL) infants. The iron concentration in preterm human milk obtained at corrected term age (42.2${\pm}$19.4 $\mu$g/dL) was significantly higher than that of mature term human milk (25.2${\pm}$7.55 $\mu$g/dL). Conclusion: The concentration of iron in preterm human milk was consistently low during the first 3 months of lactation. Supplementation with iron of at least 2 mg/kg/day should be considered for preterm infants who are exclusively breastfed and who have low body iron stores, to meet the minimum enteral iron requirements recommended by AAP-CON (2004).

  • Changes in hematology and serum biochemistry after treatment of recombinant human erythropoietin (rHuEPO, HM10760) were screened in 4 male cynomolgus monkeys (Macaca fascicularis). Four monkeys, composed of a treatment group of HM10760 and a positive control group of $Aranesp^(R}$, were subcutaneously administered at same dose of $100{\mu}g/kg$. Both groups did not show any change in body weights and food consumption for 4 weeks compared with those of pretreatment. Both groups did not show any change in total leukocyte count (WBC) and platelet count, while both groups showed increased platelet distribution width (PDW) percentage in HM10760 group during a period from day 5 to day 59 and in $Aranesp^(R}$ group during a period from day 9 to day 26. Both groups showed increases in red blood cells (RBC), hemoglobin (HGB), and hematocrit (HCT) approximately 10 days after treatment compared with those of pretreatment (day 0). The increased levels of RBC, HGB, and HCT were much higher in HM10760 than in $Aranesp^(R}$ by the increases of $3.2%{\sim}12.5%$ for RBC, $3.8%{\sim}17.1%$ for HCT, and $1.85%{\sim}11%$ for HGB. Both groups showed increases in red cells distribution width (RDW) and reticulocyte (RET) compared with those of pretreatment, showing the highest peak from day 9. The increased level of RET lasted up to day 14 in $Aranesp^(R}$ group, while it lasted up to day 23 in HM10760 group. The increased level of RDW lasted up to day 59, it was much higher in HM10760 by the increase of $10.1%{\sim}17.6%$ than in $Aranesp^(R}$ group. In serum biochemistry, both groups showed a decrease in chloride level compared with those of pretreatment. These findings indicated that HM10760 increased RBC, HGB, HCT, RDW, and RET compared with those of pretreatment, and the increased levels were much higher in HM10760 than in $Aranesp^(R}$.
