The most researches developing pattern of compression style sportswear were targeted at the live model that has muscular body build. The purpose of this study was developing a method for classifying men's lower body types in terms of muscular body build. The 3D human body scan data and body measurements of 30s of Size Korea were analyzed. The subjects (n=203) were men between the ages of 30 and 39 years. Men's muscular body build was classified with two key dimensions, thigh girth and calf girth. The subjects were divided into four groups. From each group, average subjects (n=42) whose height and weight were close to the mean value ($mean{\pm}1/2$ S.D.) were selected. 42 subjects were divided up as four groups. Group I (n=7) was thigh and calf developed body type. Group II (n=9) was thigh developed body type. Group III (n=11) was calf developed body type. Group IV (n=15) was thigh and calf undeveloped body type. Four groups had distinct different at widths (n=4), depths (n=4), and girths (n=9) dimensions. The results showed that the muscular men in their 30s could be defined by thigh and calf girths. The thigh developed muscular men had thigh girth over 60cm and the calf developed muscular men had calf girth over 38cm. From each group one representative was selected by 3D body scan figure.

Numerical measurements were made for fresh weight, body length and width, head width, and color and length of antenna of Japanese pine sawyer, Monochamus alternatus adults, a primary vector of pine wood nematode, Bursaphelenchus xylophilus in Korea. We measured 563 females and 601 males that emerged out of dead pine logs from 2001 to 2002. General linear model analysis showed that measurements of fresh weight, body length, and body width were significantly higher in females than in males. Head width was not significantly different between sexes. Antennal length of males was significantly longer than that of females. For females and males respectively, average fresh weights were 0.305g and 0.277g, body lengths 20.97mm and 19.93mm, body widths 6.52mm and 6.18mm, head widths 3.78mm and 3.70mm, and antennal lengths 31.19mm and 45.49 mm. Antennal length or ratio of antennal length to body length overlapped in some ranges between 2 sexes. Therefore antennal length itself or ratio of antennal length to body length could not be used as a definite criterion to discriminate sexes. However, check on color of the antennae of 4,033 adults revealed without exception that basal part of every segment of flagellum of female antenna was covered with whitish-grey hairs, while whole part of every segment of male flagellum was covered with brownish-black hairs. This characteristics might be a best way to differentiate sex of this species.

Background: Radiographic modalities have been commonly used to evaluate pectus carinatum (PC), and compressive orthotic bracing is the most widely accepted treatment method. The aim of this study was to determine the efficacy of 3-dimensional (3D) body surface scanning as an alternative modality for the evaluation of PC. Methods: The medical records of 63 patients with PC who were treated with compressive orthotic bracing therapy between July 2017 and February 2019 were retrospectively analyzed. Using both 2-view chest radiography (posteroanterior and lateral view) and 3D body scanning, the height of maximal protrusion of the chest wall was measured both before and after 2 weeks of bracing therapy. The difference between the pre- and post-treatment measurements was calculated for both modalities, and these differences were compared and analyzed. Results: Based on the comparison between the pre- and post-treatment radiographs, bracing therapy produced favorable outcomes in all patients (p<0.001). The measurements obtained via 3D scanning were strongly correlated with those obtained via chest radiography (r=0.60). Conclusion: Based on the findings of this study, 3D body surface scanning appears to be an effective, radiation-free, and simple method for the post-treatment follow-up evaluation of PC, and thus can be considered an alternative to radiography.

The purpose of this paper lies in the comparison of the body types between the subjects of Korean women in their 60's living in Russia and China. The findings are as follows. 1. The comparison of 80 items in physical measurements between the Korean women in their 60's living in Russia and China resulted in the differences in 57 items. While the height items including stature between them showed negligible differences, most of the length items relating to width, thickness, circumference, and obesity showed differences, which were big. 2. The analysis by using the physical measurements showed the differences in the number of the elements constituting the body types of the Korean women in their 60's, as 13 for those living in Russia and 11 for those living in China. 3. The cluster analysis for the comparison of the body types of each group, by categorizing the body types, produced three types for both groups. Koreans living in Russia were grouped as those with the short stature and light weight, the medium stature and medium weight, and the tall stature and heavy weight. Koreas living in China were classified as those with the short stature and medium weight, the tall stature and light weight, and the tall stature and heavy weight.

The purpose of this study is to provide basic data reflecting body characteristics for production of briefs by classifying lower body types of women in their 40s, 50s and 60s. The results are as follows: First, measurements for height-related items decreased while the measurements for width and depth items increased with age. However, 'hip width' and 'hip depth' items showed no significant differences among the age groups. In addition, no visible differences appeared in the length items among the age groups but 'waist to hip' and 'outside leg' lengths showed decreasing values according to age. Second, four factors were established from the factor analysis: 'obesity level around waist and abdomen', 'vertical length of the lower body', 'thickness and obesity level of lower limbs', and, 'size and shape of buttocks'. Lastly, cluster analysis resulted in the classification of the four factors mentioned above. Type 2 appeared the most, representing women in their 40s~60s. Type 1(n=257) was referred as 'slender with a short lower body', Type 2(n=443) as 'plump with short lower body', Type 3(n=224) as 'slender with long lower body', and Type 4(n=199) as 'obese around abdomen and lower limbs'.

The increase in the need for a 24 hour monitoring of biological signals has been accompanied by an increasing interest in wearable systems that can register ECG at any time and place. ECG-monitoring clothing is a wearable system that records heart function continuously, but there have been difficulties in making accurate measurements due to motion artifacts. Although various factors may cause noise in measurements due to motion, the variations in the body surface and clothing during movements that cause eventual the shifting and displacement of the electrodes is particularly noteworthy. Therefore, this study used biomedical body mapping and a motion-capture system to measure and analyze the changes in the body surface and garment during movements. It was deduced that the area where the friction and separation between the garment and skin is the lowest would be the appropriate location to place the ECG electrodes. For this study, 5 male and 5 female in their 20s were selected as subjects, and through their selected body movements, the changes in the garment and skin were analyzed using the motion-capture system. As a result, the area below the chest circumference and the area below the shoulder blades were proposed as the optimal location of electrode for ECG monitoring.

Research on the acoustic properties of fish has been carried out by a number of scientific workers from the earliest days of applying acoustic techniques to fish biomass estimates. This paper describes measurements of the target strength of Cyprinus Carpio, which measurements made at 50KHz in the experimental water tank. The results obtained are as follows: 1. The target strength(dB) of the fish has a directivity pattern quite similar to that of a transducer. The maximum value of target strength(dB) is obtained when the fish is insonified to its head-tail axis either from the dorsal or from the ventral side. 2. Empirical relationship between target strength(dB) and body length(cm) of the fish can be estimated as TS=20 Log L-65.4 where TS is the target strength of the fish and L is the body length of the fish. 3. The relationship between target strength(dB) and body weight(g) of the fish can be estimated as TS=6.7 Log W-53.7 where W is body weight of the fish.

The bone mineral density(vertebrae Ll-4, femoral neck, Ward's triangle and trochanter) of 160 healthy adult women aged 29-45 was measured and general characteristics, anthropomentric measurements, and dietary intake were also studied to determine the main factors affecting the bone mineral density(BMD) of adult women. The nutrient intake of the subjects was adequate to RDA level except energy, Ca, Fe, and vit A. The BMD of vertebrae L24 showed significant positive association with nutrient intake such as animal protein, P, Ca(animal) and Fe(animal). The BMD of the femoral neck correlated significantly with anthropometric measurements such as height, weight, waist circumference, hip circumference, body fat and body mass index. The BMD of both sites(vertebrae L24 and femoral neck) were significantly related to vertebrae L24 was daily Ca intake and that of femoral neck was daily energy expenditure. In conclusion, adequate nutrient intake, especially protein, P, Ca and Fe as well as increases in physical activity were suggested to prevent the loss of bone mineral density in adult women.

Surface characterization of materials has been considered critical in the development of biomaterials, as many unfavorable responses from the body occur at the interface between a material and the body component. The contact angle measurement is one means to characterize the surface properties and to correlate them to the biocompatibility of materials. In this paper, surface characteristics of silk fibroin/S-carboxymethyl kerateine, representative fibrous proteins, were investigated by contact angle measurements of ESCA. The biocompatibility of the blends was evaluated based on minimal interfacial free energy concept, and compared with other potential biomaterials. It was also hypothesized that the enhanced surface polarity of the blends was generated from the conformational transition of proteins. This approach to evaluate the biocompatibility of materials based on surface characteristics may find wide utility in many biomedical applications.
