The objective of this study is to develop 3D anthropometrical data acquisition method of human back surface and to recognise and extract its morphological characteristics. This technique is very useful in describing the sitter's back contour and the interaction between the sitter's back and the seat. The back surfaces of subjects in sitting posture are measured by using martine-type anthropometer and sliding gauge. These basic anthropometrical data are reconstructed into 3D image.

Purpose: Korea is expected to enter an aged society in 2018 and then a super-aged society in early 2025. The country's aging is progressing faster than any other country in the world. However, the foundation of the elderly friendly industry is weak, and measures at the government level are urgently needed. Especially, housing problems of the elderly are one of the most urgent measures to be taken. Korea does not have the minimum residential area standard for the elderly, and the current general minimum residential area standard is based on the survey of the housing situation without scientific evidence. Therefore, both standards need to be revised as soon as possible based on scientific evidence. Methods: The minimum residential area standard has been calculated following Karl H. E. Kroemer's Min or Max design also being called as-single cut and dual cut theory- as the maximum population value and minimum population value theory of Ernest J. McCormick. Therefore there is a need for a formula made using a few key factors, such as corresponding dimension, practical dimension, clearance, spare dimension, integrated dimension. These elements can be defined and used as formulas to calculate minimum residential area standards. Results: Assuming the results of the spatial variability in this study showed that it is possible to raise the standard of living in a terms of sustainable minimum size for the young, old and all residents. Implications: The government should set a minimum residential area standard with scientific grounds and set up a policy improving the life of people who live in an needy residential environment.

The ability to customize garments for fit in the apparel industry is directly tied to the availability of comprehensive and accurate sets of anthropometrical data for each consumer. The data for apparel sizing systems is available from three major standard/ research organizations: ASTM (American Society for Testing and Materials), ISO (International Standard Organization), and NCHS (National Center for Health Statistics). However, these standards ignore various head shapes and are outdated for the development future head products. This creates a data gap an ever changing multi-cultural society such as the United Sates. Although major government and industry safety organizations recognize the importance of safety for head products, few studies were found to support their reasoning. The purpose of this study is to provide accurate head dimension data for developing safety head products by analyzing various head shapes in the United Sates which includes various ethnic backgrounds. This study was carried out on 105 males in the United States. Factor analysis, cluster analysis, Moreover, Duncan analysis were all used for analyzing various head shapes.

Abnormalities in fibrinolysis system is associated with risk of hypertension. In this report, the Alu repeat insertion/deletion (I/D) polymorphism of tissue plasminogen activator (t-PA) and the Hind III RFLP of plasminogen activator inhibitor-1 (PAI-1) genes were investigated in 115 normotensives and 83 patients with hypertension, and their association with anthropometrical data and plasma biochemical parameters were analyzed. There were no significant differences in the gene frequencies of the two candidate genes between normotensives and hypertensives, respectively. Our results indicate lack of associations between the two polymorph isms in t-PA and PAI-1 genes and risk of hypertension in the population under study. However, the Hind III RFLP of PAI-1 gene was significantly associated with plasma glucose level, suggesting its role in glucose metabolism. It needs to be tested whether this RFLP of PAI-1 gene is associated with insulin resistance syndrome or non-insulin dependent diabetes mellitus (NIDDM) in the Korean population.

근지구력시간은 근피로를 평가하는 매우 중요한 지시자이다. 근지구력 시간을 직접 측정할 경우 근골격계 손상의 위험이 있다. 따라서 본 연구에서는 근지구력시간을 개인요소와 신체측정치수의 간접측정으로 예측할 수 있는 모델을 제시하려고 한다. 초기에는 개인요소인 성칭과 연령이 근지구력시간의 예측에 상관없다는 결과가 있었지만, 최근에는 팔의 중력토크(GTA, gravitational torque of the horizon arm, stretched arm)와 최대자율수축강도(MVC, maximum voluntary contraction) 등을 독립변수 또는 예측변수로 적용하여 근지구력시간을 예측하였다. 본 연구에서는 등장성 운동 시 개인요소와 신체측정치수를 이용하여 근지구력시간을 예측할 수 있는 변인들에 관하여 연구하였다. 총 25명의 피검자가 자원하여 10%,20%,30%,40% 그리고 50%MVC 강도의 등장성 운동을 수행하였다. 그 후 회귀분석을 통해 산출된 상관계수를 비교하였으며, 그 결과 다중회귀모델에서 유의성 있는 상관계수가 있었으며 근지구력시간을 예측하는 변인으로써 유용함을 알 수 있었다.

The aim of this study was to estimate the influence of 37 bp insertion/deletion (I/O) poly-morphism of the low density lipoprotein receptor-related protein-associated protein 1 (LRPAP1) gene on anthropometrical or biochemical parameters in korean general population. To determine the frequency of the genotype, we analyzed 244 samples of Korean origin. The frequency of the I allele was 0.55 in men and 0.56 in women, which were significantly higher than the frequency (0.26) that was reported in Czech population of Caucasian origin. In addition, the I allele of this polymorphism was significantly associated with higher value of body mass index (BMI) in our subjects by ANOVA test (P<0.05), and this association was maintained after controlling for age and gender by ANCOVA test (P<0.05). Thus, our results suggest that the I/O polymorphism of the LRPAP1 gene may be useful as a genetic marker for obesity in Korean general population.

The alkaline comet assay has been used with increasing popularity to investigate the level of DNA damage in biomonitoring studies within the last decade in Western countries. The purpose of this study was to evaluate the usefulness of the alkaline comet assay as a biomarker of oxidative DNA damage for monitoring in the Korean population, and also to evaluate the effect of nutritional status and lifestyle factors on H2O2 induced oxidative DNA damage measured by the alkaline comet assay in human lymphocytes. The study population consisted of 61 healthy Korean male volunteers, aged 20-28. Epidemiological background data including dietary habits, smoking habits and anthropometrical measurements were collected through personal interviews. After blood collection, the comet assay in peripheral lymphocytes and plasma lipids analysis was carried out and the results analyzed. Tail moment (TM) and tail length (TL) of the comet assay were use\ulcorner to measure DNA damage in the lymphocytes of the subjects. Statistically significant (p < 0.05) positive correlations were observed between DNA damage (TM or TL) and smoking habits expressed as cigarettes smoked per day and pack years (r = 0.311 and 0.382 for TM, r = 0.294 and 0.350 for TL, respectively). There were also significant positive correlations between DNA damage parameter and waist-hip ratio. Higher plasma triglyceride levels were associated with increased damage to DNA. There were no correlations between the consumption frequencies of vegetables and DNA damage to the subjects. However, consumption frequencies of fruit and fruit juice intake were inversely associated with the TM and TL. The results indicate that die comet assay is a simple, rapid and sensitive method for detecting lymphocyte DNA damage induced by cigarette smoking. Consumption of fruit or fruit juices could potentiall modify the damaged DNA in the human peripheral lymphocytes of young Korean men.

This study was carried out to evaluate the iron nutrition status of 212 middle school students(106 males and 106 females) residing in Seoul(13-14 years old ) using eating patterns and a measurement of anthropometrical determination and hematological indices. Fasting blood samples were taken from all subjects, serum iron (SI) and total iron binding capacity(TIBC) concentrations were measured, and transferrin saturation(TS) levels were calculated. Iron and other nutrient intakes were estimated by a semi-quantitative frequency questionnaire. The level of TS(%) which was calculated with TIBC and SI in females(20.4$\mu\textrm{g}$/dl) was significantly lower(p<0.050 than that of males (27.4$\mu\textrm{g}$/㎗). The prevalence of iron deficiency was found to be 36.7% when defined by TS(%) (<05%). Mean daily intake of total iron in the study subjects was 14mg and heme iron intake was 5.4mg(38.1%) . There was a significant negative correlation between the level of SI and the income level and a positive correlation with the level of TIBC and the income level. TIBC had a positive correlation with the anthropometric variables(Ht, Wt, BMI, RI and PIBW). SI and TS had a negative correlation with body fat percentage. There was a positive correlation between energy intake and TIBC only among females. The logistic regression analysis revealed that income level, body fat percentage , weight and energy intake were major determinants of low SI levels. Among the determinants of abnormal TIBC levels were weight , height, income level and energy intake. Finally , among those of low TS% were iron and energy intake and income level. These observations suggest that physical status, body fat percentage energy and iron intakes and income level are risk factors for iron-deficiency anemia among the middle school students in Seoul.
