In this study, weight of evidence(WOE) technique based on the bayesian method was applied to estimate the groundwater yield characteristics in the Pocheon area in Kyungki-do. The ground water preservation depends on many hydrogeologic factors that include hydrologic data, landuse data, topographic data, geological map and other natural materials, even with man-made things. All these data can be digitally collected and managed by GIS database. In the applied technique of WOE, The prior probabilities were estimated as the factors that affect the yield on lineament, geology, drainage pattern or river system density, landuse and soil. We calculated the value of the Weight W+, W- of each factor and estimated the contrast value of it. Results by the ground water yield characteristic calculations were presented in the form of posterior probability map to the consideration of in-situ samples. It is concluded that this technique is regarded as one of the effective technique for the feasibility mapping related to detection of groundwater bearing zones and its spatial pattern.

From time to time the light weight distribution has been discussed, It play an important part in the preliminary design state because of its influence on the available deadweight. Up to the past, the Light weight distribution acting on the ship has been estimated graphically by means of integraph or approximately by the simplified calculations. Recent development has made it possible to use Lloyd's coffin method or Robb's coffin method for Bulk Carrier, Tanker, Cargo ship where the hull weight is distributed based upon the $C_B$ The hull weight distribution is then super-composed by number of fixed weights(i.e. machinery , equipment, etc.) The authors built up the method by which the Light weight distribution is calculated using a computer. In the usual calculations, the higher accuracy is aimed at, the longer time would be taken, therefore the accuracy would not be so good as to be expected if the time is restricted. The method using a computer can dissolve these and calculated accurately in shorter time the Light weight distribution with less data.

Purpose: The purpose of this study was to provide basic data for the development of weight control programs to maintain and promote healthy behavior in women college students by identifying their weight control behaviors and factors that influence these behaviors. Method: Data were collected from 300 women student participants and were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression with the SPSS 18.0 program. Result: Weight control behavior showed a significant difference according to participants' gender role identity type. Weight control behaviors were correlated with self-efficacy, body image, objective BMI, and ideal BMI. Factors influencing weight control behavior were self-efficacy (${\beta}$= .449, $p$<.001), secret method for weight loss (${\beta}$= .181, $p$<.001), monthly allowance below 200,000 won (${\beta}$= .156, $p$= .006), weight control support from others (${\beta}$= .124, $p$= .013), eating breakfast (${\beta}$= .119, $p$= .015), and age (${\beta}$= .113, $p$= .023) with R-sq. value of 45.3%. Conclusion: The results of the study indicate that development of interventions for weight control behavior and health education for college women should reflect identified factors influencing weight control behavior and gender role identity.

Purpose: The purpose of this study was to examine the effect of the yoga during pregnancy on the maternal weight, delivery experience and infant birth weight. Method: The nonequivalent control group pre test-post test design was used. The participants were the healthy pregnant women, whose pre-pregnancy BMI was normal, gestational period was more than 20 weeks. The final sample consisted of 21 mother-infant dyads for experimental group and 20 dyads for control group and who agreed to participate in this study. Data were collected from February I st to December 15th, 2006. The Qi exercise prenatal program was carried out for 90 minutes a day, 2 times a week for 12 weeks. The data were analyzed using SPSS 16.0 Program. Result: The degree of maternal weight gain(p<.001), labor pain(p<.001), discomfort after delivery(p<.001) and infant's birth weight(p<.00I) were significantly different between two groups. Conclusion: The yoga during pregnancy managed weight gain of mothers. Therefore, this study suggests that yoga during pregnancy to promotes stabilization can be beneficial for maintaining healthy weight, decreasing labor pain and discomfort after delivery for pregnant women and increasing infant's birth weight.

BACKGROUND/OBJECTIVES: This study aimed to examine differences in weight control practices, beliefs, self-efficacy, and eating behaviors of weight class athletes according to weight control level. SUBJECTS/METHODS: Subjects were weight class athletes from colleges in Gyeong-gi Province. Subjects (n = 182) responded to a questionnaire assessing study variables by self-report, and data on 151 athletes were used for statistical analysis. Subjects were categorized into High vs. Normal Weight Loss (HWL, NWL) groups depending on weight control level. Data were analyzed using t-test, ANCOVA, x²-test, and multiple logistic regressions. RESULTS: Seventy-three percent of subjects were in the HWL group. The two groups showed significant differences in weight control practices such as frequency (P < 0.01), duration and magnitude of weight loss, methods, and satisfaction with weight control (P < 0.001). Multiple logistic regression showed that self-efficacy (OR: 0.846, 95% CI: 0.730, 0.980), eating behaviors during training period (OR: 1.285, 95% CI: 1.112, 1.485), and eating behaviors during the weight control period (OR: 0.731, 95% CI: 0.620, 0.863) were associated with weight control level. Compared to NWL athletes, HWL athletes agreed more strongly on the disadvantages of rapid weight loss (P < 0.05 - P < 0.01), perceived less confidence in controlling overeating after matches (P < 0.001), and making weight within their weight class (P < 0.05). HWL athletes showed more inappropriate eating behaviors than NWL athletes, especially during the weight control period (P < 0.05 - P < 0.001). CONCLUSIONS: Self-efficacy was lower and eating behaviors during pre-competition period were more inadequate in HWL athletes. Education programs should include strategies to help athletes apply appropriate methods for weight control, increase self-efficacy, and adopt desirable eating behaviors.

Objectives: The purpose of this study was to find out the relation factors of weight control behaviors, mental health status and body image perception in adolescents and to use basis data of health promotion for adolescents. Methods: This study used data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V-2, 2011). The subjects were 653 between 12-19 age. Data analysis was done with SPSS/WIN 19.0 using Chi-square test, and Logistic regression. Results: The result is as follows. The case of female adolescents, abnormal perception of body image was significantly higher on weight reduction effort and normal weight, low weight in BMI. The case of male adolescents, abnormal perception of body image was higher on normal weight in BMI. Conclusions: The adolescents tend to do unreasoning weight loss behavior without properly perception for their body image. Therefore, we suggest that adolescents be provided social support for positive body image and be developed perception program with the importance of inner values.

A sequential pattern mining is finding out frequent patterns from the data set in time order. In this field, a dynamic weighted sequential pattern mining is applied to a computing environment that changes depending on the time and it can be utilized in a variety of environments applying changes of dynamic weight. In this paper, we propose a new sequence data mining method to explore the stream data by applying the dynamic weight. This method reduces the candidate patterns that must be navigated by using the dynamic weight according to the relative time sequence, and it can find out frequent sequence patterns quickly as the data input and output using a hash structure. Using this method reduces the memory usage and processing time more than applying the existing methods. We show the importance of dynamic weighted mining through the comparison of different weighting sequential pattern mining techniques.

Purpose: The purpose of this study was to identify factors influencing desired postnatal weight loss in women after birth. Methods: With correlational survey design, 191women of the study participants completed questionnaires on their desired postnatal weight loss and related factors, and body and health concerns during their hospitalization after birth. Data were collected from February to May, 2011. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients, and multiple linear regression. Results: The women's gestational weight gain, pre-pregnant BMI, body concerns, expected time to reach the desired weight after birth and health concerns were identified as factors influencing desired postnatal weight loss in women after birth. The model explained 68% of the variance. Conclusion: Results suggest that nurses in women's health care should consider women's gestational weight, pre-pregnant BMI and their body concerns, health concerns and expected time to reach the desired weight after birth when developing weight management program for women after birth.
