The mask-face interface design should consider the face shape to improve the half mask respirator's fit ratio. This study tried to design the mask-face interface using recent Korean face data. By using the data of 1536 men's 3D face scanning (Size Korea data), head clay mock-up was made and mask-face interface line was extracted from this head mock-up. Using this interface line, the half-mask prototype was made. According to the quantitative fitting test, the proposed mask was found to be well fitted (average fit-ratio > 100). The proposed method had two advantages. 1) The method could use massive head-related anthropometric data like Size Korea data. 2) The qualitative fit test (observation) could be conducted very quickly by fitting the prototype to the head mock-up. However, this method also had several limitations. 1) The head clay mock-up could be different according to the mock-up maker. 2) The average values of the head-related anthropometric data were used to make the head mock-up. Small and large size head mock-ups should be made and tested.

Background Eyelids vary in morphology and structure depending on age, sex, and race. Usually, one-dimensional measurements are used to evaluate blepharoplasty outcomes. However, in recent years, three- or four- directional enlargements of the eyelid have been used for blepharoplasty in Asian patients, and the outcomes of techniques such as lateral canthoplasty or canthotomy and medial epicanthoplasty with increased scleral area cannot be analyzed using marginal reflex distance 1 or the area of corneal exposure. Therefore, we describe the use of a measurement method based on the eyeball exposure area (EEA). Methods To obtain normal EEA values by age and sex, 320 individuals were recruited. The participants were divided into eight age groups (n=40 in each group: female subjects, n=20; male subjects, n=20): 10-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79, and 80-89 years. The EEA value was obtained by dividing the exposed area by the total eyeball area. The normal EEA values and differences in EEA according to age and sex were calculated. Results The mean EEA values for male and female subjects were 66.86% ±9.20% and 71.48%±10.48%, respectively. In each age group, the EEA values of females were higher than those of males. EEA decreased significantly with age in both male and female subjects (P<0.05). Conclusions We determined normal EEA values according to age and sex. EEA can be used as an indicator of the outcome of blepharoplasty.

Cardiovascular disease (CVD) is one of the most common causes of death in elderly Koreans, and HDL-cholesterol is known to have a pivotal role in protecting against CVD. This study was undertaken to study the relationships between plasma HDL-cholesterol levels and dietary, anthropometric, and biochemical factors in elderly Koreans. The 102 subjects, who were over 60 years old, were classified into two groups based on their plasma HDL-cholesterol levels: a risk group with plasma HDL-cholesterol < 40mg/dl in men or HDL-cholesterol < 50mg/d1 in women, and a control group with higher HDL-cholesterol levels. The subjects' mean intakes of energy, calcium, zinc, vitamin A, vitamin $B_2$, vitamin E, and folate did not meet the Korean RDA for elderly people. Vitamin $B_2$ and folate intakes were significantly lower (p<0.l) in the risk group compared to the control group. The consumption of seaweed was significantly lower (p<0.05), and fish intake was 33% lower, in the risk group compared to the control group. Subjects in the risk group showed a higher BMI, waist/hip ratio, triceps skinfold thickness, and % body fat, compared to control subjects. Plasma triglyceride levels and values of the atherogenic index were significantly higher (p<0.00l) in risk group subjects. Significant negative correlations between HDL-cholesterol level and plasma triglyceride level (r= 0.37), and values of the atherogenic index (r=-0.74), were found. In summary, subjects with low levels of HDL-cholesterol were found to have relatively low intakes of vitamin B$_2$, folate, and seaweed, and higher levels of the CVD risk factors: body fat, plasma TG, and AI. These results suggest that plasma HDL-cholesterol levels can be modified by dietary, anthropometric, and hematological means.

Purpose: Direct anthropometry is an ideal method for preoperative planning and postoperative evaluation in plastic surgery, but it requires highly skilled specialty. Indirect anthropometry, especially photogrammetry, is an alternative method. In photogrammetry, standardized clinical photography is essential. Photogrammetry-based standardized clinical photography has several advantages over direct anthropometry. It is easier to measure and has less chance to make errors during measurement. Furthermore, it is possible to repeat measurements, and available for follow up study based on permanent custody. But, it is still different from actual measurement, and inherently less accurate than anthropometry. Methods: The authors revised the standardized clinical photography and then, carried out photogrammetry using Photoshop(Adobe, U.S.A.), and compared each data with those of anthropometry. The subjects were 50 males and 50 females, undergraduate medical students in twenties. Standard head position was obtained from the wire, fixed to cephalostat which indicates the Frankfort horizontal plane. All photographs were taken at the same situation such as fixed position of light, subject and camera, etc. Results: Total 96 measurements, based on 40 landmarks, consist of linear measurements, angular measurements and inclinations include 3 measurements in head, 22 in face, 15 in orbit, 28 in nose, 16 in lip and mouth, and 12 in ear. Conclusion: Normal photogrammetric data of face of Korean in twenties was obtained. Reliable photogrammetric measurements, not significantly different from anthropometric measurement statistically, accounted for 44 in 96 measurements(45.8%). Anthropometric values different from those of photogrammetric values were obtained by multiplying coefficient by photogrammetric value.

A nutrition survey of 198 children, 6 to 12 years old, in the Song Myeon Elementary School and Sam Song Elementary School, located in remote villages of Gaesan county, Chung Buk province, was undertaken between July 11 and 16, 1988, to investigate dietary and nutritional status. Mean values of height, weight, sitting height, arm circumference, girths of chest, and weight for height were 98%, 96%, 101%, 94%, 103% and 98%, respectively, of Korean standards. Compared with the standards for Korean children and values for Yun Jung Elementary School children of Youido, Seoul, anthropometric data of subjects surveyed showed slightly lower results than the standards and further lower results than those of Yun Jung Elementary School children. mean hematocrit value was 39.8±3.1%. 15.3% of subjects were proven to be anemic according to the hematocrit criterion established by the WHO. Mean urinary urea nitrogen/creatinine ratio was 7.9±3.3. Energy and nutrient intake were 61.2 to 134.4% of the RDA's; except for intake of ascorbic acid, most nutrients were below the RDA's. Carbohydrate provided 72% of total energy intake; protein accounted for 11%; fat provided 17%. Family environment, anthropometric data and results of biochemical tests were positively correlated with nutrient intake. The survey emphasizes the need for a nation wide school lunch program.

A nutritional survey was made in 45 healthy Buddhist nuns (age : 20-34 yr) who have been vegetarians for more than 5 years and 20 female college students (aga : 20-22 yr) as a control group in Kyungpook province. Daily calorie intake of the Buddhist nuns and students were 1947 and 1815 kcal, respectively. The ratio of percent calorie of carbohydrate : fat : protein from total calories in the Buddhist nuns was 84 : 11 : 5 and that of the students was 70 : 15 : 15, respecting. The Buddhist nuns had significatly higher carbohydrate intake but markedly lower lipid intake than the students. Daily intakes of thiamin, niacin and ascorbic acid in the Buddhist nuns were higher, but those of iron, calcium and vitamin A were lower than the recommended daily allowances. Compared with the students, the Buddhist nuns had greater intakes of ascorbic acid, vitamin A, thiamin, niacin, and calcium. Anthropometric measurement showed that the Buddhist nuns had significantly higher values than the students in body weight, skinfold thickness, body surface area, and obesity index. There were highly significant correlations between anthropometric measurements and obesity index(0.55< r <0.99). On the other hands, correlation coefficients between nutrients intakes and skinfold thickness and obesity were very low(0.01< r <0.37). The Buddhist nuns and students showed similar normal values of hemoglobin concentration, hematocrit, and blood pressure.

This study was performed to study the effects of dietary factors on breast and cervical cancer incidence in female Koreans. The subjects were 60 breast and 109 cervical cancer patients recruited from five general hospitals in Seoul. Food intake, anthropometric measurement, and blood compositions were studied through personal interview and using medical records, from August 1991 to September 1992. Body weight, body mass index, triceps skinfold thickness and body muscle mass were at upper limit of normal value, which suggest that these patients had a tendency of overweight. The levels of hemoglobin and hematocrit of the patients were below the normal values. The values of serum protein, albumin, and calcium were in the normal range but close to the lower bound. Therefore the nutritional status assessed by blood composition seems to be marginal. The results of diet history showed that most of the nutrient intake of the subjects met with RDA. The fat intake were 22.9-36.9g/day which supplies about 15-16% of total calories. The results of this study do not agree with those reports of western societies which showed the positive correlation between calorie and fat intake and the incidence of breast and cervical cancer. Even through the calories and fat intake of the subjects were not high, it was higher than national average, especially in breast cancer patients. From this study, dietary factors does not seem to be a major risk factor in cancer incidence in Korea. However, the tendency of the increasing consumption of fat could be a contributing risk factor together with overweight.

The purpose of this study was to classify size specifications of the Korean adult male for the men's ready-made garments, especially jacket and dress shirts. By the stratified sampling method, data were collected by the real anthropometric measurement and by the photo-graphic sources. Sample size was 532 subjects as the sample and their age range was from 28 to 35 years old. 66 variables from the direct anthropometric data in total were applied to analyze. ANOVA in SPSS WIN package was applied to the data and the expected frequency distribution of 10.000 men was calculated by the extraction of density function. This study was performed to classify size specifications by the control dimensions and at the same interval of KS-K. The drop values of 15, 12 and 9 have the high coverage rate of 26.00%, 24.29% and 21.06% respectively and are composed of the majority of 71.35% of the subjects. According to the drop values, size specifications and distribution of control and reference dimensions are predicted. About 52.12% of the expected frequency distribution without stature were covered by 12 size specifications.
