The purpose of this study is to investigate the standard weight and the perception of the figure, making girls' high school students the object of scientific study. Furthemore this study will try to find the factor having an effect on the weight through measuring the concern with appearance and health. The study consisted of 658 girls' high school students in Seoul. The data was analyzed by the methods of frequency, percentage, reliability, pearson's correlation coefficient and multiple regression analysis. The results of this study are as follows : 1. The standard size of girls height was 160.95cm, their weight was 52.06kg. 2. 34 percent of the girls tested perceived of themselves of having proper figures. Especially in the case of overweight girls. Only 9.7 percent of girls were satisfied with their figure, the other 83.3 percent were not. 3. 88.4 percent of the girls were concerned with their weight. It was through mass communecation that girls were concerned with wheir weight. 41.2 percent of the girls were concerned with weight much more through mass communication than through any other things. This showed that the effect of mass communication on juveniles was increased. 4. The result of correlation of variable about the concern with appearance(p<0.001), the perception of their figures(p<0.001), the existence of weight controller in friends (p<0.001) and the concern with health(p<0.001) indicated significant positive correlation, on the other hand, the satisfaction of their figures(p<0.001) indicated negative correlation. This showed that the less satisfactory their figures were, the higher their concern about weight was. 5. In order th seize the variable having an effect on the concern with weight, the result of multiple regression analysis was that the concern with appearance (p<0.001), the satisfaction of figure (p<0.001), the concern with health (p<0.05), poket money (p<0.05) and health condition (p<0.05) had a statistically significant effect and the variables also 35.7% out of this model. Concern with appearance had the most important effect of all these variables.

A general linearly constrained adaptive array is examined in the weight vector space to illustrate the array performance with respect to the gain factor. A narrowband linear adaptive array is implemented in a coherent signal environment. It is shown that the gain factor in the general linearly constrained adaptive array has an effect on the linear constraint gain of the conventional linearly constrained adaptive array. It is observed that a variation of the gain factor of the general linearly constrained adaptive array results in a variation of the distance between the constraint plane and the origin in the translated weight vector space. Simulation results are shown to demonstrate the effect of the gain factor on the nulling performance.

An efficient stereo matching method with variable matching weights is proposed. The edge segment-based stereo matching has been shown to be efficient method. The method includes 5 matching factor with different weights. The ordinary matching weights are not always adequate for every image. Employing different weight sets depending on the complexity shows better matching performance. In this paper, an evaluation criterion for complexity is suggested and the experimental results with the proposed method is shown.

Objective: The purpose of this study was to examine the effect of increase in barbell weight on closely related variable to the anterior cruciate ligament (ACL) injury which are knee joint kinematics, joint load, joint moment, and maximum load attainment point during snatch of the weight lifting. Method: The subjects of the study were 10 male Korean national weight lifting athletes (69 kg 5, 77 kg 5; age: $21.80{\pm}3.91yrs.$, height: $168.00{\pm}4.06cm$, weight: $75.00{\pm}4.02kg$, career: $7.8{\pm}3.99yrs.$, snatch records: $168{\pm}4.06kg$). The weight of the barbell during the snatch operation was set at 70%, 75% and 80% of the highest records for each subject studied. Results: The result obtained from the one-way repeated measure ANOVA are as follows: With increased barbell weight, the extension moment of the left knee joint was higher in the 80% condition than the 70% (p<.001). However, other variables were not statistically significant difference. According to the factor analysis of the variables related to maximum load attainment point of the ACL major injury variables, the first sub-factor was the internal shear force, the posterior shear force, the abduction moment, and the muscle activity of the VL. The second sub-factor was the extension moment of the knee joint, compressive force, adduction moment, and the third sub-factor was the muscle activity of BF. Conclusion: These results indicate that the possibility of ACL injury can be lowered when performing a stable snatch movement.

For urban renewal projects progressing in large scale, it carries a characteristic that frequently changes the environment, subject, law, plan and the like by a demand from various participants and internal/external factors. As such large-scale urban renewal projects have a lot of possibilities of change, it requires setting a plan to recognize the possible variable factors by each project operation stage and to manage it systematically by defining the variable factors on the basis of working process of the entire project. Therefore this research has produced a factor of main variable management based on working process for systematic variable management on the projects that inherent various possibilities of change as urban environment refurbishment projects. And it also suggests the status of main variable factors characterized by project operation stages quantitatively through reflecting external and internal features for variable factors produced from utilizing ANP methodology.

This study was conducted in North Sulawesi, Indonesia to identify the factors affecting reproductive efficiency and to determine the contribution of each factor in reproductive efficiency of Indonesian native cows. Records of reproductive efficiency, body size (hip height, body weight, body length, heart girth) as well as age on one hundred and sixty seven Indonesian native cows (seventy six cows of the Bali breed and ninety one cows of the synthetic breed from unknown proportion of th Madura, the Sumba and the Ongole breeds) of 58 farmers were available in this research. The data were analyzed by covariance analysis using SAS package including reproductive efficiency as a dependent variable and breed, body size (hip height, body weight, body length, heart girth) and age of cows as independent variables. The contribution of each independent factor to dependent variable was estimated as the percentage of the sum of square in the corrected total sum of squares. The results showed that body weight and body size of cows would be considered as th most important factors affecting reproductive efficiency of Indonesian native cows. Therefore, the reproductive efficiency could be increased by 1) using cows that reached a target weight of at least 250 kg, 2) using cows with relatively well developed height at hip of at least 117 cm, heart girth of at least 150 cm, and body length of at least 125 cm, 3) keeping breeding cows that reach a target age of 24 months old with the maximum interval between postpartum and next breeding season of 90 days for each year, and 4) using good nutritional feeding to reach the optimum weight and body condition.

Adaptive Bit Loading (ABL) in Multiple-Input Multiple-Output Orthogonal Frequency-Division Multiplexing (MIMO-OFDM) is often used to achieve the desired Bit Error Rate (BER) performance in wireless systems. In this paper, we discuss some of the bit loading algorithms, compare them in terms of the BER performance, and present an effective and concise Adaptive Grouped Loading (AGL) algorithm. Furthermore, we propose a "weight factor" for loading algorithm to converge rapidly to the final solution for various data rate with variable Signal to Noise Ratio (SNR) gaps. In particular, we consider the bit loading in near optimal Singular Value Decomposition (SVD) based MIMO-OFDM system. While using SVD based system, the system requires perfect Channel State Information (CSI) of channel transfer function at the transmitter. This scenario of SVD based system is taken as an ideal case for the comparison of loading algorithms and to show the actual enhancement achievable by our AGL algorithm. Irrespective of the CSI requirement imposed by the mode of the system itself, ABL demands high level of feedback. Grouped Loading (GL) would reduce the feedback requirement depending upon the group size. However, this also leads to considerable degradation in BER performance. In our AGL algorithm, groups are formed with a number of consecutive sub-channels belonging to the same transmit antenna, with individual gains satisfying predefined criteria. Simulation results show that the proposed "weight factor" leads a loading algorithm to rapid convergence for various data rates with variable SNR gap values and AGL requires much lesser CSI compared to GL for the same BER performance.

In this paper, we develop an electrostatic monitoring system which is composed of an electrostatic prediction system and a warning message transmission system. The electrostatic prediction system in a factory receives the value of electrostatic charge from the electrostatic sensor and predicts the next value by using past data and sends the value to the warning message transmission system through the bluetooth communication. The warning message transmission system gets a warning signal and transmits the warning message to the worker's cellphone through a commercial SMS web by a socket program running on Windows PC in a control room. We propose electrostatic forecasting algorithms based on LSR(least square regression) using weight factors in an electrostatic prediction system. Simulation results show that the algorithm with dynamically variable weight factors is best with 64.69V standard deviation and a warning message transmitted by the warning message transmission system is displayed on cellphone after about 5 seconds.

The purpose of this study was to classify appearance management attitudes into groups and analyze the difference of self-efficacy and body satisfaction by the groups. Questionnaires were administered to 255 college students living in Deagu Metropolitan City and Kyungbook province. The data collected were analyzed by using frequency, factor analysis, cluster analysis, correlation analysis, ANOVA, Duncan-test, t-test, and ${\chi}^2$-test. The findings were as follows. Appearance management attitudes of college students were classified into three groups such as group health body, low body interest group, emphasizes collective body. The appearance management attitudes showed significant correlation with the sub-variables of self-efficacy and body satisfaction. Male students showed no significant difference in self-efficacy by the groups while female students showed a significant one in task performance which was a sub-variable of self-efficacy. Both of the male and female students showed a significance of difference in the gap between actual and ideal weight which was a sub-variable of body satisfaction by the groups. Gender of college students showed distinction between the sub-variables of self-efficacy factors such as task performance, and anxiety and body satisfaction such as BMI, the difference between current height and ideal height, the difference between current weight and ideal weight.
