Protein-bound polysaccharide is derived from Acanthopananx senticosus by the cold water extraction. The aim of the study was to evaluate the effects of PS against weight loss and hematological change as a indication of toxicity produced by the treatment of cisplatin. PS protected the weight loss caused by cisplatin (6 mg/kg) and significantly recovered hematological change. Treatment of PS showed the recovery on the weight loss and hematological change as indicators of toxicity of cisplatin treatment. By increasing lymphocyte proliferation and cytokine production, PS may be highly effective in protecting against cisplatin-induced toxicity. The results suggest PS might have a role in reducing toxicity or permitting larger dose of cisplatin to be given.

Purpose: This study aims to provide preliminary data for weight management, and prevention and management of cardiovascular and cerebrovascular diseases. We examined the effect of changes in the weight of workers at a manufacturing company over three years on their metabolic syndrome and metabolic syndrome diagnosis components. Methods: Necessary data were collected from the questionnaire and the results of the Korean National Health Screening of 2015 and 2017, which included 228 workers at a manufacturing company in G region. The collected data were analyzed using the SPSS/WIN 23.0 program. ANCOVA was used to examine the differences in the metabolic syndrome diagnosis components according to weight change. In addition, multiple logistic regression analysis was used to obtain the odds ratios of metabolic syndrome and metabolic syndrome analysis component, based on the weight changes in the normal weight group and the obesity group. Results: Waist measure, systolic blood pressure, and blood pressure were found to have significant effects based on participants' weight change over three years. These factors increased with a larger increase in weight at a statistically significant level. This study analyzed the weight changes of the normal weight group and the obesity group considering the data from the National Health Screening of 2015, and found that the risk of metabolic syndrome increased at a statistically significant level as body weight increased; thus, the obesity group showed a higher risk in this regard. It was also found that waist measure, fasting blood sugar, and high-density low cholesterol increased at a statistically significant level as body weight increased. Conclusion: Health administrators need to recognize the importance of workers' weight management, select an intensive management group based on a time series analysis of weight changes, and develop and implement programs to manage the metabolic syndrome diagnosis components.

This study aims to examine changes from differences in the lumbar scoliosis angle and iliac crest height due to abnormal and habitual posture shown in unilateral weight load at standing posture and suggest data for preventing and treating lumbago. The subjects of this study are 16 lumbago patients between twenties and forties with chronic lumbago over six months, but without neurological symptoms. As a result of photographing front and back with three conditions such as weight load on both sides and left or right unilateral weight load posture in order to examine changes of lumbar scoliosis and iliac crest according to changes of posture at unilateral weight load, while scoliosis angle and iliac crest height by habitual unilateral support were increased, those by opposite support were decreased. In conclusion, it was found that habitual unilateral weight load may cause continuous distortion of spinal angle and change of iliac crest height and these may be a factor of lumbago. Therefore, if habitual unilateral weight load state is kept continuously, distortion of lumbar angle and iliac crest height may be greater and common efforts to change habitual unilateral weight load are needed.

Maternal body weight, skinfold thickness and circumference measurements were examined in 23 lactating women and 10 nonlactating women longitudinally from 1 week to 12 weeks postpartum. The dietary intakes of Korean lactating and nonlactating women were measured by 24-hour recall method and effects of maternal energy intake on body weight change were analyzed by Pearson correlation. The mean daily energy intake of breast-feeding(BF, n=12), combination of breast and formula-feeding (CF, n=11), and formula-feeding (FF, n=10) mothers were 1941kcal, 187kcal and 1727kcal, respectively. A significant decrease in weight was observed at all group. Weight losses at 12 weeks of postpartum in BF, CF and FF motheres were 3.18kg, 3.91kg and 5.15kg respectively. Weight losses increased as calorie intake decreased (${\gamma}$2=0.3803, p<0.05). The skinfold thickness and circumferences on all regions were decreased significantly except triceps and upper arm circumferences. However, there were no significant differences between lactating and nonlactating women. Anthropometric measurements decreased at the trunk but not at the limbs. Weight change was significantly correlated with changes of the scores for proximal circumference (${\gamma}$2=0.4999, p<0.05). There results suggest that lactation does not promete weight loss in well-nourished women and that the Korean RDA for energy in lactation may be too high.

Objectives The purpose of this study was to investigate the clinical effect of oriental medical therapy on obesity and the progress of weight loss through an oriental obesity program. Methods The subjects were treated from January 2008 to February 2009 in J Korean Medical Hospital. Herbal medical Hospital. Herbal medicine, electrolipolysis, auricular acupuncture were performed during the treatment period. We checked the change of weight every treatment time and measured the body composition by bioelectrical impedance analysis(BIA) every 2 weeks. Results The progress of weight loss was steady in the first 4 weeks except for the sixth weight check. After 4 weeks treatment, the weight loss was 3.52${\pm}$1.98Kg and 4.83${\pm}$2.68%. Total fat mass measured by BIA significantly decreased 2.58${\pm}$1.30Kg after 4 weeks. Age and the weight loss were significantly negative correlated. Conclusions Oriental obesity treatment could be effective on obesity, but further studies would be needed for the foundation of a clinical guideline reflecting various factors.

This paper describes a deadweight force standard machine with the weight change mechanism which can be used as a primary force standards at a national metrology institute. Since commercial deadweight force machine can generate forces by hanging weights to the weight supporter serially, force steps from deadweight force measuring devices of each having different capacity. In order to increase the force steps, we have specially designed a weight mechanism in which the machine can select the necessary weights and generate the load by hanging the selected weights to the weight supporter. The machine can generate 속 force of the range of 2 kN to 110 kN with force step of 1 kN. All weights have been accurately compensated and calibrated by a mass comparator and its standard uncertainty is less than 2.2 ${\times}\;10^{-6}$. The relative expanded uncertainty of the machine is 1.3 ${\times}\;10^{-5}$.

Floor impact sound in high-rise apartment building became one of social problems. A lot of civil complaints on floor impact sound occur continuously and the number of disputes between neighbors in small and aged apartment buildings is increasing. Interests on heavy-weight impact sound pressure level measurement and evaluation method is increased. Previous study reported that heavy-weight impact sound level was changed by the sound field condition of receiving reverberation chamber. In this study, heavy-weight impact sound pressure level change by the receiving sound field condition was measured in standard test facility and mock-up test room. These two experimental conditions were designed to simulate averaged living room of common apartment units. By the change of sound absorption power in receiving room, heavy-weight impact sound pressure level in most of frequency bands were changed in standard test facility and mock-up room. Normalized maximum sound pressure level regulated in ISO 16032 showed wider range of heavy/soft impact sound pressure level. Heavy/soft impact sound pressure level change was became smaller by the application of standardized maximum sound pressure level and ISO/CD 10140-3 Amd 2 method. In the case of standardized maximum sound pressure level, absolute sound pressure level changed. From these results, receiving sound field correction method regulated in ISO/CD 10140-3 Amd 2 is needed for the precision measurement and evaluation of heavy-weight impact sound.
