The Effect of Taekwondo Training on Aerobic Capacity, MVO2, ST Slope and QRS Duration / 체질인류학회지

The purpose of this study was to investigate the effects of taekwondo training on VO2max, MVO2 and electrocardiogram ST slope, QRS duration in college woman. Subject were divided into two groups, one is taekwondo group (n=11) and the other is control group (n=10). They participated in graded exercise test (Balke protocol) and measured aerobic capacity and electrocardiogram. The aerobic capacity (VO2max and AT) was measured by autogas analyser. The resting and exercise rate-pressure product (RPP) could be measured with HR and systolic BP for MVO2 measurement. The electrocardiogram ST slope, QRS duration was calculated using automated software program (QMC). The measured data were analyzed by using paired t -test. The results of this study were as follows : There was a significant difference of VO2max and AT between taekwondo group and control group. VO2max of taekwondo group was 4~5 mL/kg/min higher than control group (p<0.01) and AT also taekwondo group was 3.4% higher than control group (p<0.05). There was no significant difference of maximal exercise MVO2 between taekwondo and control group. There was no significant difference of electrocardiogram ST slope between group but rest QRS duration in taekwondo group was longer than the control group (p<0.01). Conclusively, these data suggest that regular taekwondo training will strengthen on aerobic capacity and resting slow heart beats.

Physical Anthropologic Characteristics of the Auricle through the Metric and Non-metric Analysis in Korean Young Adults / 체질인류학회지

The auricle, which has a subtle structure, is an element that conveys signs of age or sex and decides the facial characteristic. The anatomy of the auricle differs in each individual as well as in each race. Therefore, the anatomy of the auricle can be useful for physical anthropologist to classify the race of a person or for a forensic anthropologist to identify the body of dead person. Also, a standard measurement of a normal ear is required for plastic surgeons to reconstruct an ear or artists to express the ear. Studies on the auricle of Caucasians and Koreans have been reported. However, further study on the classification of the location and shape of the auricle is necessary. The authors investigated the metric and non-metric characteristics to obtain basic data that display physical anthropologic features. Seven hundreds and thirty three Koreans under 39 years old and over 18 years old were examined. Metric items investigated were the length of the auricle, width of the auricle, morphological width of the ear, physiognomic ear length, physiognomic ear breadth, morphologic ear breadth, length of the ear cartilage, length of the ear lobule, and the height of the tragus. Non-metric items investigated were the location of the ear, shape of the helix and antihelix, and the attaching shape of the lobule. According to the metric results, all measured values were significantly greater in males than females, and there was a sexual difference except the width of the auricle, length of the ear lobule, and the height of the tragus. In non-metric results of the auricle, cases where the superaurale was located at the upper area of the eyebrow line and cases where the superaurale was between the eyebrow line and the upper eyelid showed similar rates among males. However, in 87.5% of the female group, the superaurale was located between the eyebrow line and the upper eyelid. The major shape of the helix were oval type (32.6%) and quadrilateral type (30.5%) in males, but oval type (32.7%) and triangular type (33.0%) in females. We believe that the data obtained in this study have generated standard measurements for ear reconstruction and can be used as basic data that show physical anthropologic characteristics of the Korean auricle.

Morphologic Study of the Rectus Abdominis Muscle for Flap Surgery / 체질인류학회지

Forty-nine cadaver dissections (male 30, female 19) were performed to identify the shape and size of rectus abdominis muscle and the distribution of vessels in Korean for flap surgery. The total length between xiphoid process and pubic symphysis of male is 375.9+/-41.8 mm and female is 339.4+/-39.1 mm. But the length between umbilicus and pubic symphysis of male and female did not show significant difference. The three tendinous intersections are 61.2%, the 4 intersections are 35.7%, and 2 intersections are 3.1%. The most of first, second and third intersections had the most complete intersection. The most of fourth intersection had the most fragmentary intersection. The external diameter of superior epigastric artery is 1.4+/-0.3 mm, and inferior epigastric artery is 2.6+/-0.6 mm. The percentage of superior epigastric artery that goes into the medial 1/3 region of rectus abdominis muscle is 52%, middle 1/3 region is 38%, lateral 1/3 region is 2% and 2 stem goes into the muscle is 8%. The length between the origin of inferior epigastric artery and the point of semilunar line met inferior epigastric artery is 41.1 mm in male and 38.8 mm in female.

Anthropological Study on the Facial Flatness of Korean from the Historic to the Modern Period / 체질인류학회지

The facial flatness was studied by the metric method which involves six measurements of breadth and projection of the midfacial skeleton, the calculation of three indices from the measurements. The indices of the modern Korean adult crania, Korea & Chosun Dynasty crania, the Iron Age Korean crania, and the late Neolithic Korean crania were investigated. The indices were compared to those of other published data on the Korean crania and those of neighboring asian races as well. All indices for facial flatness of Korea & Chosun Dynasty were similar to modern Korean. However, zygomaxillary index was different between modern and late Neolithic crania. The difference of zygomaxillary index was prominent in males than females. The difference of facial flatness between modern and ancient seems to be mainly due to zygomatic breadth. The frontal indices of modern Korean and Korea & Chosun Dynasty crania were relatively low and the simotic indices were relatively high among neighboring asian races. The zygomaxillary index is intermediate. Clustering analysis represented that the flatnesses of the modern Korean crania and Korea & Chosun Dynasty crania were closely related to those of the northern Chinese, modern Japanese, however, somewhat different from that of ancient Korean, Mongol, Siberian etc.

Metric and Non-metric Traits of the Teeth in Past and Present Koreans / 체질인류학회지

Teeth play an important role in mastication and phonation as well as in esthetics. Since metric and non-metric characteristics of teeth can be used in anthropological comparison, archeology and identification, they are very important in physical anthropology, archeology and forensic odontology. However, this subject has rarely been studied in Koreans and therefore data on the anthropological characteristics are scarce. Researchers have measured 5 factors on each tooth and 9 non-metric characteristics of 1085 teeth collected from Gaya, Korea and Chosun people and 1397 teeth collected from the present Koreans (both female and male). Metric and non-metric traits of the teeth were compared in past and present Koreans. Comparing the measurement of the teeth in past and present Koreans, no difference in the faciolingual diameter was seen while slight difference was seen in the mesiodistal diameter of past and present Koreans. Non-metric traits of Koreans showed that 96.4% of past Koreans and 94.2% of present Koreans had shoveling in the maxillary central incisior while 93.1% of past Koreans and 90.6% of present Koreans had shoveling in the maxillary lateral incisor. Therefore shoveling was present in a higher rate in the past Koreans. The result on the comparison of the lingual cusp number on mandibular second premolars, showed that while past Koreans had 1 (48.0%) or 2 (52.0%) lingual cusps, present Koreans had 1 (52.3%), 2 (46.7%) or 3 (1.0%) lingual cusps. The Terra's tubercle was seen on the mesial surface in 53.7% of maxillary first premolar in the present Koreans and 48.7% of maxillary second premolar showed no tubercle. Meanwhile, past Koreans showed a higher rate of Terra's tubercle than present Koreans. Frequence of Carabelli's tubercle in the maxillary first molar was 18.4% in past Koreans and 36.2% in present Koreans. The most common form of occlusal groove pattern in the maxillary first molar was '4' (94.3% in past Koreans, 94.3% in present Koreans) and in the maxillary second molar was '4-' (40.5% in past Koreans, 76.5% in present Koreans). In both the past and present Koreans, The 'Y5' pattern of occlusal groove pattern was most common in the mandibular first molar and '+4' pattern in the mandibular second molar.

Measurements of the Zygomatic Bones and Morphology of the Zygomaticofacial and Zygomaticotemporal foramina in Korean / 체질인류학회지

In order to clarify the anthropological characteristics of the zygomatic bones that influence to the facial morphology, authors measured the metric dimensions of the zygomatic bones and observed the non -metric traits of Korean 192 skulls (122 males, 43 females, and unknown 27 cases). The results were as follows. In the anterior aspects of the skull, the bizygomatic breadth was 134.8 +/-6.0 mm in the male and 126.6 +/-5.5 mm in the female and the bijugale breadth was 117.3 +/-5.1 mm and 110.1 +/-4.0 mm in the male and female, respectively. The mid -orbital breadth was 53.5 +/-5.7 mm in the male and 52.2 +/-4.7 mm in the female and the bimaxillary breadth was 98.9 +/-5.0 mm in the male and 94.8 +/-4.4 mm in the female. In the lateral aspects of the skulls, the distance from the porion to the ectoconchion (oder - tiefe) was 71.1 +/-2.7 mm in the female and 69.0 +/-3.0 mm in the female and the distance between the porion and the jugale (ohrjochbeinlange) was 54.2 +/-2.7 mm in the male and 53.1 +/-2.7 mm in the female. The maximum zygomatic length was 54.5 +/-3.7 mm in the male and 50.5 +/-2.9 mm in the female and the zygomatic height was 49.6 +/-3.0 mm in the male and 45.8 +/-2.4 mm in the female. The incidences of the absence of the zygomaticofacial foramina and the zygomaticotemporal foramina were 12.0% and 7.3%, respectively. The average number of the zygomaticofacial and the zygomaticotemporal foramina was 1.7 and 0.8, respectively. The positions of these foramina located on the bodies of the zygomatic bones in many cases, and the other cases were that these foramina located on the frontal processes of the zygomatic bones or on the borderlines of the body and frontal process.
