As compared with body height and body weight by ages and sexes, by means of the data reported under other researchers from 1967 to 1994 for 33 years, this study obtained the estimate value of body height and body weight by ages and sexes for the same period, and figured out prediction value of body height and body weight in the ages of between 6 and 14 from 1995 to 2000. These surveys and measurements took for one year from October 1st 1994 to September 30th. As shown in the 〈Table 1〉, in order to calculate the establishment, estimate value and prediction value of the chronological regression model of body height and body weight, by well-grounded 17 representative research papers, this research statistically tested propriety of liner regression model by the residual analysis in advance of being reconciled to simple liner regression model by the autonomous variable-year and the subordinate variable-body weight and measured prediction value, theoretical value from 1962 to 1994 by means of 2nd or 3rd polynomial regression model, with this redult did prediction value from 1995 to 2000. 1. Chronological Change of Body Height and Body Weight The analysis result from regression model of the chronological body height and body weight for the aged 6 - 16 in both sexes ranging from 1962 to 1994, corned from the 〈Table 2-20〉. On the one hand, the measurement value of respective researchers had a bit changes by ages with age growing, but the other hand, theoretical value, prediction value showed the regular increase by the stages and all values indicated a straight line on growth and development with age growing. That is, in case of the aged 6, males had 109.93cm in 1962 and females 108.93cm, but we found the increase that males had 1I8.0cm, females 1I3.9cm. In theoretical value, prediction value, males showed the increase from 109.88cm to 1I7.89cm and females from 109.27cm to 1I5.64cm respectively. There was the same inclination toward all ages. 2. Comparision to Measurement Value and Prediction Value of Body Height and Body Weight in 1994 As shown in the 〈Table 21〉, in case of body height, measurement value and prediction value of body height and body weight by ages and sexes almost showed the similiar inclination and poor grade, in case of body weight, prediction value in males had a bit low value by all ages, and prediction value in females had a high value in adolescence, to the contrary, a low value in adult. 3. Prediction Value of Body Height and Body Weight from 1995 to 2000 This research showed that body height and body weight remarkably increased in adolescence but slowly in adult. This study represented that Korean physique was on the increase and must be measured continually hereafter.

In Med Dept. Daehan Education Insurance, Total 690 cases(male 376 cases, female 314 cases) were inspected to study the change of serum lipid value. The objects of investigation were total cholesterol, HDL cholesterol, triglyceride, phospholipid and total lipid value. The results are as follows: 1) In the normal subjects, with the relation of serum lipid value and the age. triglyceride, phospholipid and total lipid value showed the increasing tendency by 70 age, but total cholesterol value and HDL cholesterol value showed the increasing tendency by 59 age and the decreasing tendency after 59 age. 2) In the normal subject the difference of serum lipid value between sexes did not make the significant difference of level statistically in all items which can be inspected. 3) The weight change and serum lipid value are very significantly related. Total cholesterol, HDL cholesterol and total lipid value are high in female if the weight is light. But they are high in male the weight is heavy phospholipid value is opposite to the above result. Triglyceride value is high in male regardless the weight, but the significant difference happened in the high weight group. 4) As serum lipid value of hypertension patients is compared with that of the normal subjects, HDL cholesterol, triglyceride, phospholipid and total lipid value are significantly high. 5) The doubtful group of the fatty infittration of liver among the hypertension pafients have very significant difference in serum lipid value compared with not only the value of the normal subject but also that of the obesity group. 6) The doubtless group of the fatty infitration of liver among the hypertension patients have the significant difference in all serum lipid value compared with that of the normal subject, but compared with the obesity group males had the significant difference of HDL cholesterol value and both sexes had the significant difference in total lipid value, but had no significant difference in total cholesterol, triglyceride and phosprolipid value. 7) The ratio of total cholesterol per HDL cholesterol had the significant difference in the doubtful hypertension patients of the fatty infittration of liver and the relative weight, but it had no significant difference compared with the normal subject in the doubtless hypertension patients.

In order to calculate construction costs properly, it is necessary to add the weight that reflects different worksite conditions. The implementation of the weight, however, is difficult because it is impossible to determine whether wight should be added in basic work or whether weight values are overlapped. Special worksite conditions further complicate the matter. Furthermore, overlapping implementation of weight values result in overestimation of construction costs. The current study clearly analyzed the weight value items in the current construction cost calculation standards, and analyzed the weight value items included under the basic productivity category to propose an improvement of weight standards. Basically, the estimating standards provide 140 weight value items, with different levels of weight given to each item. Among 1,333 items in the estimating standards, 140 include weight values. Some items have two types of weight values.

The purpose of this study was l)to compare a pelvic tilt angle between sound side and affected side in hemiplegic patients, 2)to determine the difference of weight bearing and weight shifting between sound and affected lower extremity according to the pelvic tilt angle. The subject for the study were 40 hemiplegic patients(mean age of 55.6 years)without orthopedic disability on pelvic bone. The data were analyzed by t-test, one way ANOVA, Multiple comparison and Range. The results of this study were as follows : 1. There was a significant difference in the pelvic tilt angle between sound side and affected side in hemiplegic patients(p<0.05). 2. There was a significant difference in the weight bearing value between sound and affected side in hemiplegic patients according to the posterior pelvic tilt angle(F = 12.43, df = 3/36, p<0.001). Therefore, the lesser the posterior pelvic tilt angle, the higher the weight bearing value on the affected side. 3. The lesser the posterior pelvic tilt angle, the higher the weight shifting value on the affected side. 4. There was a significant difference in weight bearing value between sound and affected side according to the grade spasticity(F = 3.61, df = 4/35, p<0.05). Therefore, the higher the grade spasticity, the lower the weight bearing value on affected side.

To study the characteristic of the weight center control of humans, the tracking control capability of circular and wave motion by weight center movement was conducted by using the force platform. The control performance(the integrated value of the $|Object\;value(X)-Control\;Value(Y)|^{2}$) and control trace record was used to evaluate the individual performance characteristics. The size of the population for this study was 73, which consisted of engineering students, students majoring in taekwondo, students majoring in dance, all of which were in their twenties, and also people in their sixties. The results of this study indicate that the weight center control characteristics of humans can be represented by the evaluation method and values. People who were capable of tracking the object did not stop nor overshot the objective. In addition, habits or training characteristics and aging seemed to influence the performance of the subjects. In the future, development of different objectives for weight center control could be used to determine the severity of the disease of the subject and the effects of the treatment.

Records of a Northeastern Thai indigenous cattle line population were used to estimate genetic parameters and annual trends for calf weights. The data set comprised records of 1,922 and 1,489 animals for birth and weaning weight, respectively born from 1993 to 2004. A bivariate analysis was carried out for variance and covariance components estimations using average information restricted maximum likelihood procedure. Average estimated breeding value and maternal breeding value of the animals born in 1993 were set to zero as a base group. Genetic trends of each trait were calculated by regressing average estimated breeding values and maternal breeding values on birth year of calves. Phenotypic trends for each trait were calculated by regressing the yearly adjusted weight on birth year of calves. The results revealed that the estimate of direct heritability, maternal heritability and maternal permanent environmental variance as a proportion of phenotypic variance for birth and weaning weight was 0.40, 0.14 and 0.04; 0.27, 0.05 and 0.23, respectively. Direct heritability was moderately heritable and genetic improvement through selection can be achieved. The estimate of phenotypic, direct genetic, maternal genetic and maternal permanent environmental correlation between birth and weaning weight was 0.48, 0.65, 0.98 and 0.73, respectively. The phenotypic trend, genetic trends of estimated breeding value and maternal breeding value for birth weight was 0.18, 0.04 and 0.01 kg/year, respectively. The phenotypic trend, genetic trends of estimated breeding value and maternal breeding value for weaning weight was -1.36, 0.32 and 0.03 kg/year, respectively. As maternal genetic effect was considerably less important than direct genetic effect, selection for improved weaning weight of this Northeastern Thai indigenous cattle line can place more emphasis on the direct genetic effect.

This paper presents a new learning method for a noise tolerant Fuzzy ART. In the conventional Fuzzy ART, the top-down and bottom-up weight vectors have the same value. They are updated by a fuzzy AND operation between the input vector and the current value of the top-down or bottom- up weight vectors. However, it can not prevent the abrupt change of the weight vector and can not achieve good performance for a noisy input vector. To solve the problems, we updated using the weighted sum of the input vector and the current value of the top-down vector. To achieve stability, the bottom-up weight vector is updated using the fuzzy AND operation between the newly learned top-down vector and the current value of the bottom-up vector. Computer simulations show that the proposed method prominently resolves the category proliferation problem without increasing the training epoch for stabilization in noisy environments.

Compressed sensing-based matching pursuit algorithms can estimate the sparse channel of massive multiple input multiple-output systems with short pilot sequences. Although they have the advantages of low computational complexity and low pilot overhead, their accuracy remains insufficient. Simply multiplying the weight value and the estimated channel obtained in different iterations can only improve the accuracy of channel estimation under conditions of low signal-to-noise ratio (SNR), whereas it degrades accuracy under conditions of high SNR. To address this issue, an improved weighted matching pursuit algorithm is proposed, which obtains a suitable weight value u_op by training the channel data. The step of the weight value increasing with successive iterations is calculated according to the sparsity of the channel and u_op. Adjusting the weight value adaptively over the iterations can further improve the accuracy of estimation. The results of simulations conducted to evaluate the proposed algorithm show that it exhibits improved performance in terms of accuracy compared to previous methods under conditions of both high and low SNR.
