눈으로만 보는 관리에서 실제 수치를 적용시키는 보다 과학적인 관리가 전문가들에 의해서 주장 되어 오고 있다. 즉 육성기에 있는 닭들의 체중을 정기적으로 자주 측정하여 이 측정치를 체계적으로 분석 검토하므로서 흔히 발생하는 문제점들을 미연에 방지할 수 있도록 관리 방법을 신속히 수정하자는 것이다.

In this study, a method for estimating the amount of urination for men, was suggested and its performance was evaluated. This study is a preliminary one for the development of a health monitoring system that needs un-constraining, non-intrusive and long-term measurements in daily life. To estimate the amount of urination, a wide weighing plate with load cell was built and the difference in a man's weights between before and after urination was measured while he was standing on the plate. The results showed that the amount of urination can be estimated with the measured weight difference under the condition of mild movements. The largest measurement error of the suggested method was 40g, which means that this method can be applied to health monitoring in daily life. It is expected that the results of this study will be the basis for developing practical un-constraining and non-intrusive health monitoring system for daily use at home.

돼지의 체중 측정은 양돈시 아주 중요한 작업이다. 돼지의 체중 측정을 통해 돼지의 건강 상태를 파악 할 수 있고, 또, 공급해야 할 사료의 양과 종류를 결정할 수 있으며, 온도조절장치, 위생상태, 급사공간 등을 결정할 수 있기 때문이다. 특히, 돼지고기 생산비의 75∼80% 정도를 차지하는 사료의 급여는 돼지의 계속적인 체중을 측정하여 증체량을 팡락학 그에 따른 사료 선정과 급여량을 최적화 함으로써 경제적 손실을 최소화할 수 있다. (중략)

성계편입전의 체중측정은 어떤 사료를 얼마나 급여할 것인가를 결정하여 줄 수 있으므로 정확한 기록은 올바른 산란계관리의 지침과 예고서가 될 수 있다. 또한 체중에 따라서 사료의 제한급이 여부나 제한량을 결정하는 것이 제일 확실한 방법이다.

The objective of this study was to investigate the correlation among the measurements of the body weight and shank length at the age of 0, 4, 8, 12, 16 and 20 wk, and to investigate the regression of the final body weight at the age of 20 wk in selection on the body weight and shank length before 12 wk of age. From the simple correlation analysis, the range of correlation coefficients between body weight and shank length at the same age were 0.50~0.83 from females, and 0.57~0.85 from males over all wk of age(P＜0.01). Correlation coefficient between the body weights at hatch and 20 wk of age was 0.44(P＜0.01), but it was not significant(P＞0.05) between the shank length at hatch and body weight at 20 wk of age. The favorable regression models for the estimation of the body weight at the age of 20 wk from both body weight and shank length before 12 wk of age were the models with the independent variables of measurements at hatch and 12 wk of age($R^2$＝0.96), with the measurements at 8 and 12 wk of age($R^2$＝0.96), and with the measurements at 0, 8 and 12 wk of age ($R^2$＝0.96).

Purpose: The purpose of our study is to provide useful information for me-asurement methods of childhood obesity and to provide clinical significance of bioelectrical impedance analysis. Methods: We measured height, weight, waist to hip ratio, skinfold thickness and bioelectrical impedance from 206 elementary students in Kwangju from May to July 1997. Results: In males; 1) There were statistically high correlations between tri-ceps skinfold thickness and body mass index (BMI), percentage of body fat (%BF), weight, Rohler index (RI), total fat weight (TFW), waist to hip (W/H) ratio, height, lean body mass (LBM) (all, p<0.001). 2) There were statistically high correlations between subscapular skinfold thickness and BMI, RI, weig-ht, %BF, TBW (all, p<0.001). 3) There were statistically high correlations between %BF and BMI, triceps skinfold thickness, RI, TFW, subscapular skinfold thickness, weight (all, p<0.001). In females; 4) There were statistically high correlations between triceps skinfold thickness and BMI, weight, LBM, height, %BF (all, p<0.001). 5) There were statistically significant correlations between subscapular skinfold thickness and BMI, weight, LBM, RI, height. 6) There were statistically high correlations between percentage of body fat and BMI, RI, triceps skinfold thickness. The percentage of body fat according to the bioelectrical impedance analysis highly correlated with that calculated by skinfold thickness in males (r＝0.57, p<0.01) and in females (r＝0.30, p<0.01). Conclusion: The results of our study suggests that bioelectrical impedance analysis is a useful method of estimating body fat in the childhood obesity.

The purpose of this study was to investigate the change of physical fitness, MDA, SOD after short-term weight reduction through exercise, food restriction and exhalation of sweat among Taekwondo players. The subjects ten male collage Taekwondo players with excellent practical skills, and more than seven years of experiences. They were asked to reduce about 5% of their body weight in seven days. Physical fitness levels were analyzed through grip strength, muscle endurance, flexibility, power, agility, balance, reaction time and MDA and SOD through blood test. The results of this study were as follows; First, there was no significant change in physical fitness due to short-term weight reduction in muscle strength, muscle endurance, flexibility, power, agility, balance and reaction time. Second, The change of MDA and SOD, resulting from short-term weight reduction did not show significant difference statistically. Therefore, the results of this study indicate that the Taekwondo players' short-term weight reduction of 5% of their body weight did not influence on their athletic performance and physiological capacity. Therefore athletes and coaches should endeavor to take exercise, dietary, and dehydration into consideration when conducting 5% of their body weight reduction in a week.

본 논문에서는 운동 전후 또는 심장 질환과 관련 있는 사용자가 체중을 측정하면서 동시에 심전도 신호를 측정하여 운동 부하에 따른 심장의 활동 상태를 모니터링 할 수 있는 장치를 고안하였다. 이를 위한 방법으로 체중계에 수정된 바이폴라 금속전극을 적용하여 표준사지 측정법을 이용하여 심장활동 신호를 측정할 수 있는 방법을 제안하였다. 체중계에서 심전도를 측정하기 위해 기존의 Ag-AgCl 전극이 아닌 금속 판 형태의 전극을 사용하였으며 이를 위해 입력 임피던스의 설계를 브릿지 형의 AC-Coupling 회로를 통해 높은 CMRR이 유지되도록 설계하였다. 또한 시시각각 변화하는 노이즈를 제거하기 위해 Savitzky-golay filter를 사용하였으며 이를 통해 Baseline wandering 이 제거된 최종 심장활동 신호를 획득하였다. R-peak 검출을 통해 기준신호와의 심박수 및 Sensitivity의 비교평가를 수행하여 이 장치의 성능을 평가한 결과 심박 검출률의 평균 Sensitivity가 97.1%로 나타났다. 동잡음 제거에 대한 알고리즘이 보다 최적화 되어 최종 출력 신호의 안정성이 향상 된다면 체중계를 통한 심박 검출의 가능성과 그 유효성이 충분할 것으로 사료된다.
