  • Objectives : This study was performed to investigate the relationship between Sasang Constitution and length of chest and abdomen region. Methods : Forty eight participants were enrolled. Weight, height, and lengths from CV22 to CV16, from CV16 to CV8, and from CV8 to CV2 were measured. Ratios of last three lengths to total CV22 to CV2 were calculated respectively. On the other hand, Sasang Constitution was analyzed with QSCCII(Questionnaire of Sasang Constitutional Classification II). The analysis of relationship between the measurements and Sasang Constitution was carried out with SPSS to compare the mean values according to Sasang Constitution. Results : All the mean values were not significantly different depending on the Sasang Constitution, except the ratio of the length from CV16 to CV8 to the length from CV22 to CV2, only in female participants. The ratio was higher in the female Soeumin participants than any other constitutional groups. Conclusions : This result showed that Soeumin could be assumed that they might have weak digestion abilities.

  • The present study aims to analyze the biological aspects and population dynamics of Indian mackerel in Barru waters. Data was collected in Barru for 11 months, from June 2022 to April 2023. The observed parameters of biological aspects included gonadal maturation stages (GMSs), size at first gonadal maturation, and length-weight relationship. Meanwhile, the aspects of population dynamics encompass age group, growth, mortality rate, and exploitation rate. Data analysis consisted of morphological selection of general maturation stages, Spearman-Kärber method in estimating gonadal first maturation size, Bhattacharya method in identifying age group, von Bertalanffy function through FISAT II to measure growth (L and K), Pauly Model to estimate mortality rate, Beverton & Holt Model to estimate Y/R, and virtual population analysis (VPA) analysis to estimate stock and fish yield. The results demonstrated that GMS I was observed to be dominant, followed by stages II and III. The initial gonadal maturation was estimated to be 17.98-19.28 cm (FL) for females and 17.98-19.27 cm (FL) for males. The length-weight relationship in male and female Indian mackerels indicated a positive allometric growth. The mode grouping analysis results from the fork length measurement revealed three age groups. It was also identified that the asymptotic length (L) = 29.5 cm (fork length), growth rate coefficient (K) = 0.46 per year, and theoretical age at zero length (t0) = -0.3576 per year. Total mortality (Z) = 2.67 per year, natural mortality (M) = 1.10 per year, fishing mortality (F) = 1.57 per year, and exploitation rate (E) = 0.59, the actual Y/R = 0.083 gram/recruitment, and optimal Y/R 0.03 gram/recruitment. Fishing mortality is higher than the natural mortality rate, and a high exploitation value (E > 0.5) also reflects over-exploitation. VPA analysis on fish yields and stock estimation reported a highly exploited rate between the 11.5 cm and 14.5 cm length classes and an exceeding current yield of 467.07 tons/year with a recommended yield of 233.53 tons/year to ensure population sustainability.

  • The interrelationships between growth rates (and size) of the selected cranifacial dimensions and body dimensions (height and weight) were investigated in the longitudinal data of primary school children from 6 to 11 years of age. The data were obtained from serial cephalometric radiographs and health record which were taken at one year interval. Regression analyses were used to analyze the data. The main concludions might be summarized as follows; 1. Size relationships between body height (and weigh) and S-Gn, posterior facial height (s-Go), total mandibular length (Ar-Gn) showed high significant correlation, but no association between body height, weight and anterior cranial base length (S-N). 2. Correlation coefficients between facial dimensions and body height (and weight) were getting lower with age increase. 3. At all age groups, significant prediction equation for some facial dimensions with body height and weight were obtained. 4. In this sample, the growth rates of facial dimensions and body height and weight showed almostly constant during this age period and the growth rate of body height and weight of girls was exceeded that of boys. 5. A relatively high degree of variation between individuals existed in the sample. 6. A positive correlation was found for the relationship between the growth rates of facial dimensions and those of body height (and weight) in boys and girls, but was not found in total samples.

  • A natural, tidal-flat clone of Zoysia sinica was studied to compare ramet growth properties in central area with in peripheral area. In new stolon and rhizome, internode length, weight, shoot height and weight, and spike production were monitored on July 25, 2004. The weight/height rate of shoot between stolon and rhizome, the shoot/stolon (or rhizome) rate in weight between central and peripheral area were not different. However, other properties differed in stolon from rhizome or between central and peripheral area significantly differed: 1. The rhizome in central area had a larger node number, shorter internode length, higher shoot height, larger shoot biomass, and higher rate of non-shoot nodes than that in peripheral area. 2. The stolon in central area had a smaller node number, shorter internode length, and smaller biomass than that in peripheral area. 3. In the same area, the rhizome had a larger node number (except for central area), shorter internode, higher shoot height, larger shoot biomass, higher rate of non-shoot node, and higher rate of node having over two shoots than the stolon. No relationship could be found between shoot size and spike production in shoot on vertical rhizome (lower node of old shoot).

  • Elevated maternal plasma homocysteine concentrations have been associated with adverse pregnancy outcomes, including birth defects, low birth weight, preeclampsia, spontaneous abortion, placental abruption, and other maternal or fetal complications. The purpose of this study was to assess the maternal plasma homocysteine level during pregnancy and to investigate the relationship between the plasma homocysteine concentrations and pregnancy outcomes. Venous blood samples were drawn from 82 pregnant women who were grouped with gestational age, 1st trimester (n = 26), 2nd trimester (n = 27) and 3rd trimester (n = 29). The concentration of plasma homocysteine was analyzed by HPLC, and pregnancy outcomes including gestational length, maternal weight gain, infant birth weight, and Apgar score were collected with the medical records of the pregnant women. The levels of plasma homocysteine of the pregnant women at the 1st, 2nd, and 3rd trimester were 5.7 $$\pm$ 3.7\mu㏖/L,\;5.6 \pm4.1\mu㏖/L\; and\; 7.0\pm 4.5\mu㏖/L$, respectively, which had not showed any significant difference. The result of this study showed that in case of the pregnant women at the 1st trimester, the maternal plasma homocysteine level of the pregnant women whose gestational length was less than 38 weeks was significantly high (p < 0.01) compared to that of the pregnants whose gestational length was more than 38 weeks. And also, the level of homocysteine of the pregnant women at the 2nd trimester was significantly low when the maternal weight gain was high (p < 0.05). These findings suggest that maternal plasma homocysteine level at early stage of gestation will be a predicter of gestational length and maternal weight gain.

  • 본 연구에서는 다른 환경에서 채집된 윤충류 개체의 체장을 측정하고 기존에 제시된 윤충류 생체량 측정 방법에 적용하여, 생체량 값의 분포 검증 및 비교를 실시하였다. 이를 바탕으로 적절한 윤충류 생체량 계산 방법에 대해 고찰하고, 체장 측정 없이 종별 생체량의 대푯값을 사용하는 것이 가능한지에 대한 여부를 판단했다. 검증을 위한 대상으로 국내외적으로 우점하고 단순한 형태를 가지는 Polyarthra 속을 선정, 한강, 낙동강 및 팔당호에서 시료를 채집, 분석하였다. 지점에 따른 Polyarthra spp. 개체의 체장은 통계적으로 유의한 차이를 나타내어, 지점별 체장의 차이가 생체량 대푯값을 이용하는데 발생하는 오차의 원인이 될 수 있는 것으로 분석되었다. 보다 정확한 생체량 계산을 위해 윤충류 개체의 체장 측정은 필수적인 것으로 판단되며, 생체량 계산 시 오차가 5% 이하일 확률을 99% 이상으로 높이기 위해서는 44개체 이상의 체장을 측정해야 하는 것으로 나타났다. 측정한 체장을 이용한 생체량 계산에는 EPA 계산식 대비 McCauley (1984)의 계산식을 사용하는 것이 보다 적합할 것으로 보이지만, 기술 검증이 어려운 항목이기 때문에 향후 본 조사에서 보여진 지점 간 변이 이외에 윤충류의 복잡한 형태 및 다양한 부속지의 변화 등을 고려하여 다양한 종을 대상으로 한 추가적인 분석이 필요할 것으로 판단된다.

  • To understand the relationship among different quantitative traits, correlation studies were performed by utilizing eighty-eight inbred strains of silkworm, Bombyx mori L. on twelve economic characters. Analysis resulted in correlation of 5th instar period with total larval period (r = 0.7882), cocoon weight with shell weight (r = 0.8326), shell weight with shell ratio (r = 0.5067), shell ratio with raw silk % (r = 0.7570), raw silk % with filament length (r = 0.3490), filament size (denier) with reelability (r = 0.3193) and boil-off loss % (r = 0.2792). Negative correlation was observed among filament length with filament size (r = 0.7582) and reelability with boil-off loss % (r = -0.3236). Correlation of different quantitative characters for quality silk production is discussed.

  • Purpose : The aim of this study was to investigate the relationship between weight-supporting asymmetry and gait symmetry in patients with stroke. Methods : Sixty two stroke patients with hemiplegia stood quietly with eye opens on a force platform to calculate weight-supporting asymmetry from vertical reaction force. The GAITRite was used to evaluate their gait parameters. The data were analyzed using Pearson correlation. Results : The results of this study was showed that the medio-lateral index (ML) was correlated with symmetry rate (SR), symmetry index (SI), and Gait asymmetry (GA) of step time and length but stronger correlation with spatial gait symmetry than temporal symmetry. In gait symmetry, step length has stronger correlation with weight-supporting asymmetry than step time. Conclusions : The results of this study shows weight-supporting asymmetry was correlated with more spatial gait symmetry than temporal symmetry.
