In the construction industry, Case-Based Reasoning (CBR) is considered to be the most suitable approach and determining the attribute weights is an important CBR problem. In this paper, a method is proposed for determining attribute weights that are calculated with attribute relation. The basic items of consideration were qualitative and quantitative influence factors. These quantitative factors were related to the qualitative factors to develop a Cost Drivers-structural equation model which can be used to estimate construction cost by considering attribute weight. The process of determining the attribute weight-structural equation model consists o 4 phases: selecting the predominant Cost Drivers for the SEM, applying the Cost Driers in the SEM, determining and verifying the attribute weights and deriving the Cost Estimation Equation. This study develops a cost estimating technique that complements the CBR method with a Cost Drivers-structural equation model which can be actively used during the schematic estimating phases of construction.

Objectives Excess weight and obesity are a crucial public health problem worldwide and are considered as the main cause of many chronic diseases. The present study evaluated the effects of Aronia melanocarpa extract (AMEX) supplementation on body compositions in overweight or obese people. Methods This randomized, double-blind, placebo-controlled clinical trial was carried out on 66 healthy overweight or obese peoples. The eligible subjects were divided into AMEX and placebo supplement treatment for 12 weeks. Anthropometrics, body composition (dual-energy X-ray absorptiometry), and blood analysis were performed preand post intervention. Results We observed significant reductions in the body weight and body mass index in both groups; however, the decrease was higher in the AMEX group. Body fat mass and percent body fat showed a tendency to decreases after AMEX supplementation. No clinically significant changes were observed for any safety parameter. Conclusions In conclusion, the data of this trial indicate that AMEX were not effective in reducing body compositions, but as a safe supplement, it may help weight loss in overweight or obese people.

Purpose: This study was to examine the effect of an obesity management program on the body weight, body-mass index, and physiological index of obese female high school students. Method: Students from one school were selected as the experimental group, and students from another school as a control group so the latter group wasn't exposed to the experiment. The experimental group and the control group were each organized with 20 students. The experimental group received 60 minutes of behavior modification once a week, for eight weeks. Result: The Body weight, and Body mass-Index of the experimental group significantly decreased after the obesity management program. Total-cholesterol, T-G, and LDL-C significantly decreased and HDL-C increased in the experimental group. Total-cholesterol, T-G, LDL-C and HDL-C between the experimental group and control group showed significant differences. Conclusion: These results indicate that the obesity management program had a great effect on decreasing the body weight and body-mass index of the female obese high school students, normalizing their physiological index. In conclusion, this program turned out to be one of the safest and most effective obesity-management methods that could be applied to female high school students.

Tactical Information Communication Network(TICN) is a concept-type integrated Military Communication system that enables precise command control and decision making by unifying the diversified military communication network and conveying diverse range of battle field information on real-time, at right place at right time. TICN is designed to advance into high speed, large capacity, long distance wireless relay transmission. To support mobility in battlefield environments, the application of Ad-hoc networking technology to its wireless communication has been examined. Ad-hoc network is consist of mobile nodes and nodes in the network depends on the cooperation of other nodes for forwarding of packets. In this context, some non-cooperating nodes may delay forwarding of packets or drop the packets. This may hamper the network as a whole and disrupt communication between the cooperating nodes. To solve this problem, we present a solution with a Node Weight Management Server(NWMS), which manages each node's weight according to its behavior in local area. When the NWMS detects misbehaving node, it increases the node's weight. If the node's weight exceeds a predefined threshold then the NWMS broadcasts the node's information into network to isolate the misbehaving node from the network. These mechanisms show that they are highly effective and can reliably detect a multitude of misbehaving node.

The purpose of this study was to classify sex role identity into groups and analyze the difference of social face sensitivity and appearance management behaviors by sex role identity. Questionnaires were administered to 306 people in their twenties and thirties living in Daegu Metropolitan City and Kyoungbuk province. The data was analyzed by using frequency, factor analysis, credibility, ${\chi}^2$-test, ANOVA, Duncan-test, and t-test. The findings were as follows. Sex role identity were classified into four groups (androgyny, masculineness, feminineness, and undifferentiation). Men in androgyny group showed the highest rate of 41.3% followed by undifferentiation(24.7%), masculineness(21.3%), and feminineness(12.7%). Women in undifferentiation group showed the highest rate of 35.9% followed by feminineness(24.4%), androgyny(23.7%), and masculineness(16.0%). Social face sensitivity were composed of four factors (consciousness of being embarrassed, social formality, other consciousness, and prestige). Appearance management behaviors were composed of six factors (skin management, fashion image management, plastic surgery management, weight management, hair management, and health management). According to the result of a significant difference between social face sensitivity and appearance management behaviors by sex role identity, male showed significant difference between the sub-variables of social face sensitivity factors (consciousness of being embarrassed, social formality, and other consciousness). Both of the male and female showed a significance of difference in consciousness of being embarrassed, and social formality. Male showed significant difference between the sub-variables of appearance management behaviors factors (fashion image management, weight management, hair management, and health management). Both of the male and female showed a significance of difference in fashion image management. Gender of twenties and thirties showed distinction between the sub-variables of social face sensitivity factors (consciousness of being embarrassed, and prestige) and appearance management behaviors (skin management, fashion image management, plastic surgery management, weight management, and hair management).

Products are assumed to be spoiled and not recoverable when the raw material below the prescribed weight level is charged in the mold. The raw material is autoscaled and their weight is normally distributed with a given variance. This paper describes an appropriate stochastic model of determining the optimum weight allowance and the associated defective rate for auto scale system. The optimum weight allowance and the defective rate which minimizes the total loss of defective and the excess weight allowance is obtained. A numerical example for the existing rubber company is also presented and evaluated.

Environmental conditions may cause the quality change of fruits during distribution after harvest. In order to prevent the damage or quality change of fruits for distribution, the characteristic of fruits affected by the environmental conditions such as temperature, humidity under various distribution conditions should be known. This research was performed to analyze how the environmental conditions affect the factors such as weight loss rate and ethylene production of the peach under several distribution conditions. Environmental conditions of the actual distributed route were evaluated and the data obtained from the conditions were used for the simulated environmental tests. Regression models of the weight loss rate and the ethylene production of peach were developed and used in predicting peach quality. The weight loss rate of the peach estimated by the ASHRAE data was shown the higher value on the transportation temperature condition than on the low and room temperature conditions. The weight loss rate and the ethylene production of the peach on the simulated distribution conditions were measured and the measured weight loss rate of peach was the smaller than the theoretically estimated one. The regression models of the weight loss rate and the ethylene production were developed respectively.
