The purpose of this study was to determine the effect of compression clothing on the body shape of the human subjects. Thirty seven healthy females being overweighted with local adiposity on the buttocks and legs between the ages of 20's to 50's were used as the human subjects for the study. The selected subjects wore the compression clothing during 60 days by 8 hours a day. At the start(T0), after 30(T30) and after 60 days of treatment(T60), a cutaneous echography was measured on the right trochanter area of each volunteer in order to assess the thickness of the subcutaneous fatty tissue. At the start(T0), after 30(T30) and after 60 days of treatment(T60), the body weight of each volunteer was taken and the instrumental variations of skinfold measurements of the abdominal fold and inner thigh circumference of the waist, hips and thigh were conducted. The results show that the echography and weight loss of subjects were reduced to 8.34% and 2.08% after 60 days, respectively. Moreover, the skinfold of subjects was also reduced. Finally, skin elastometry of subjects increased.

Human body is hard to be in perfect balance during walking. Most of time the trunk is supported by one leg and the center of mass(COM) falls to the contralateral side. Thus, dynamic variables such as the velocity of the COM should be considered when gait stability is evaluated. The purpose of this study was to investigate whether the extrapolated center of mass(XCom) which utilized the COM position and its velocity, is appropriate to evaluate gait stability. Ten healthy adults participated in this study and performed 3 different types of gaits(normal(NG), hands on waists(HWG), and hands on shoulders(HSG)) onto 4 different types of obstacle(obstacle height: 0%, 30%, 40% and 50% of leg length). Medio-lateral Com-CoP and XCom-CoP inclination angle were calculated during support phase. For all condition, greater M-L XCoM-CoP inclination angles were found(p<.05) compared with those of matched obstacle height CoM-CoP. Especially, M-L XCoM-CoP inclination angle at 50% height revealed the best condition for monitoring dynamic stability. Significantly increased in M-L XCoM-CoP inclination angle was found(p<.05) as obstacle height increased on NG and HWG.

Objectives: Plasma lipid profiles and Apolipoprotein E (ApoE) are established risk factors for cardiovascular disease (CVD). The knowledge of lipid profile may estimate the potential victims of cardiovascular disease before its initiation and progression and offers the opportunity for primary prevention. The most common ApoE polymorphism has been found to influence plasma lipid concentrations and its correlation with CVD has been extensively investigated in the last decade. Methods: The ApoE polymorphism and its influence on plasma lipid were investigated in healthy woman workers. The information on confounding factors was obtained through a self-administered questionnaire and ApoE polymorphism was investigated using PCR. Results: The relative frequencies of alleles E2, E3 and E4 for the study population (n = 305) were 0.127, 0.750 and 0.121, respectively. ApoE polymorphism was associated with variations in plasma HDL-cholesterol lipid profile. In order to estimate the independent effects of alleles E2 and E4, as compared with E3, on lipid profile, multiple regression was performed after adjustment for confounding variables such as age, BMI, blood pressure, education status, insulin, fasting glucose, HOMA-IR, menopause. ApoE2 had a negative association with HDL cholesterol and ApoE4 had a positive association with LDL cholesterol. Conclusions: This study identified that the ApoE and CVD risk factors contribute to the lipid profiles, similar to other studies. The analysis including dietary intake and other gene in further studies may help to identify clear effects on lipid profiles as risk factor for CVD.

This study investigated factors affecting the bone mineral density (BMD) of Korean young adult women (20~30 yrs) living in Seoul, according to the state of employment. Data on BMD and anthropometric and biochemical measurements were obtained from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V) (2010~2011). BMD of the working group (WG) was generally higher than that of the non-working group (NWG). The prevalence of osteopenia, and osteoporosis between the groups was 29.0/31.5%, and 12.9/18.5% from 20~29 yrs as well as 25.5/24.1%, and 20.2/20.5% from 30~39 yrs, respectively. From 20~29 yrs, prevalence of osteopenia and osteoporosis in the WG was lower than that of the NWG. Alkaline phosphatase activity of the WG was lower than that of the NWG. In the WG, from 20~29 yrs, total femur BMD showed significant positive correlations with waist circumstance and BMI. In the NWG, from 20~29 yrs, total femur, femoral neck, and lumbar spine BMDs showed significant positive correlations with weight and fat mass, whereas they showed significant negative correlations with vitamin D. In the WG, from 30~39 yrs, total femur and femoral neck BMDs showed significant positive correlations with weight and free fat mass. The results of this study show that BMD of young adult women is insufficient regardless of their employment status. Therefore, practical and systematic programs are required to improve the BMD of young adult women as well as to maintain healthy bone levels.

The main purpose of this study was to investigate factors that affect bone mineral density (BMD) in Korean adult women ($20{\sim}80{\leq}yr$). Data on BMD, anthropometric (height, weight, body mass index, waist circumference, and body fat), and biochemical (total cholesterol, vitamin D, and alkaline phosphatase) measurements were obtained from the Fourth and Fifth Korea National Health and Nutrition Examination Surveys (KNHANES, 2008~2011). Overall, the BMD of subjects had decreased from year to year: the T-scores decreased from 0.657 (2008~2009) to 0.295 (2010~2011) in 40~49 yr group and from 0.076 to -0.081 in 50~59 yr group. Age was negatively associated with BMD (T-scores of 0.388 in 20~29 yr group and -1.952 in ${\geq}80yr$ group for total femoral). BMD continuously increased with increased weight and body mass index (BMI). High values of total cholesterol (T-scores of -0.005 in 201~229 mg/dL group and -0.094 in ${\geq}230mg/dL$ group for total femoral) and alkaline phosphatase (T-scores of 0.481 in ${\geq}102IU/L$ group and -0.674 in ${\geq}336IU/L$ group for total femoral) were associated with lower BMD. Overall height, weight, and BMI were positively associated with BMD, whereas total cholesterol and alkaline phosphatase (ALP) were negatively associated with BMD. Findings of the present study show that bone loss may be associated with various factors such as age, weight, BMI, total cholesterol, and ALP et al., and that much attention should be paid to bone health of adult women. Therefore, practical and systematic programs are required to improve the BMD of adult women as well as to maintain healthy bone levels.

본 연구는 에너지 섭취 급원에 따라 골격근육량과 에너지 섭취량 간의 연관성이 달라지는지 알아보기 위해 수행되었다. 본 연구는 2008 ~ 2010년도 국민건강영양조사 자료를 이용하여 30세 이상 한국 성인 7,922명을 대상으로 각 식품의 에너지섭취비율을 기반으로 식사패턴을 분류하고 각 식사패턴 군집 내에서 대상자들의 골격근육량과 에너지 섭취량 간의 연관성을 분석하였다. 대상자의 22가지 식품군의 에너지 섭취량을 기준으로 군집분석을 실시한 결과 남성과 여성 모두에서 '밀가루와 유지류 (Flour, Animal fat)', '흰 쌀 (White rice)', '건강혼합식 (Healthy mixed diet)' 3가지 식사패턴을 도출하였다. 그 중 '흰 쌀' 식사패턴에서 남성 (p < 0.0001)과 여성 (p < 0.0195) 모두 에너지 섭취량과 골격근육량의 연관성이 있었으며, 나머지 식사패턴에서는 근육량과 에너지 섭취량 간의 관련성이 통계적으로 유의하지 않았다. 본 연구의 결과에서 30대 이상 한국 성인들의 골격근육량의 변화와 에너지 섭취량 간에는 유의한 양적 연관성이 있으나 대상자가 주로 섭취하는 식사 형태에 따라 에너지 섭취와 골격근육량의 연관성이 다른 것을 알 수 있었다. 본 연구의 결과에 근거하여, 골격근육량과 연관된 에너지 섭취량의 변화 [14]는 쌀밥 위주의 식사를 하는 한국 성인에 특이적인 결과임을 추정할 수 있다. 이는 에너지 섭취량의 증가 없이도 군집에 속한 식품의 영양소 균형이 골격근육량 유지에 도움을 주는 다른 식사패턴 (예, 건강혼합식)과는 달리 쌀밥위주의 식사가 전형적인 한국인의 경우 전체적인 식사량의 확보도 골격근육 유지에 중요함을 제시하는 결과이며 쌀밥 위주의 식사를 하는 대상자들의 체중감량식단이나 근감소증 비율이 상대적으로 높은 노인들의 식사 지침에 응용할 수 있을 것으로 기대된다.

Objectives : This study was undertaken to examine the metabolomic changes due to gender and diurnal variation at sampling time and to identify an appropriate time point for urine sampling in epidemiologic studies using metabolomic profiles. Methods : Urine samples were collected twice a day (morning and afternoon) from 20 healthy Korean adults after fasting for 8 hours. The metabolomic assay was investigated using $^1H$ NMR spectroscopy coupled with the principal components analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The metabolites responsible for differentiation between groups were identified through the loading plot of PLS-DA and quantified using Chenomx NMR Suite with a 600 MHz library. Results : Metabolites responsible for differentiation in gender and sampling time were creatinine, trimethyl anine oxide (TMAO), hippurate, mannitol, citrate and acetoacetate. Dimethylamine showed difference only as a factor of diurnal time. The level of creatinine was higher in men compared to women, and the levels of citrate, TMAO, hippurate, mannitol, and acetoacetate were higher in women compared to men. The levels of creatinine, TMAO, hippurate, dimethylamine and mannitol were higher in the morning rather than the afternoon while those of citrate and acetoacetate were higher in the afternoon rather than the morning. Conclusions : Since urinary metabolomic profiles varied by gender and diurnal cycle, urine sampling should be performed at the same time point for all participants in epidemiologic studies using metabolomic profiles.

Objectives: This study was performed to investigate the effect of cold stress on heart rate variability and peripheral blood flow by Doppler ultrasound in healthy subjects. Methods: We classified the subjects by their Yin or Yang tendency using a Yin-Yang questionnaire. Cold stress was taken on the left hand of subjects for 10 seconds. Heart rate variability and peripheral blood flow were measured on the right radial artery before and after cold stress. Results: The Yang tendency group showed a significant decrease of heart rate after cold stress which was not seen in the Yin tendency group. The Yang tendency group showed a decrease of LF, total power, and increase of HF after cold stress, while the Yin tendency group showed the opposite. However, there were no statistically significant differences of heart rate variability analysis between the results of the two groups before and after cold stress. Recovery time of blood flow velocity by ultrasound Doppler was significantly different between the Yin and Yang tendency groups after cold stress. Conclusion: These results suggest that people with Yin or Yang tendency may show different responses in the autonomic nervous system. Further modified studies may include the responses to various manipulation techniques in acupuncture treatment and the individual responses according to pattern identification in traditional Korean medicine.
