  • Purpose: This study investigated the eating behaviors of Chinese children using the Nutrition Quotient for Children (NQ-C). Methods: The research subjects were 336 students (166 boys and 170 girls) in the 5th and 6th years at two elementary schools in Shandong Province and Jiangsu Province. Results: The average score of the Children's NQ was good, reaching 69.6 points. The factor scores for balance, moderation, diversity, regularity, and practice were 58.8, 84.9, 63.6, 76.1, and 73.6 points, respectively. Compared with the diagnostic cut-off points of the factors, mean balance, moderation, regularity, and practice scores were above the cut-off points, but diversity score did not meet the cut-off points. Fathers' education level showed positive correlation with the balance, regularity, and NQ scores of the students. Mothers' education level also showed positive correlation with the balance and regularity scores and mother's employment showed positive correlation with regularity score. As the exercise hours per day increased, the NQ score also increased. Conclusion: The questionnaire of NQ-C developed in Korea can be used in assessment of nutrition behavior of Chinese elementary students who have similar eating patterns.

  • The propensity score method is used to minimize the bias level in social survey, which comes from nonresponse. The theoretical concept and the background of the propensity score method is discussed first. The propensity score method was first applied in the epidemiology observational study. I have summarized the process of the three propensity score methods that were used to reduce estimation bias in this study. Matching by propensity score is applied to the relatively large control group. Subclassification has the advantage of using whole control group data and regression adjustment is applied to multiple covariates as well as propensity score of each unit is computable and usable. Lastly, the application procedures of propensity score method to reduce the nonresponse bias is suggested and its applicability to real situation is reviewed with the existing data.

  • After analyzing data of 797 Middle and High School students, the results show that those using cognitive reappraisal strategies adjusted better in school life than those using expressive suppression strategies in regards to application of emotional regulation strategies. In gender differences of the application, male students adjusted better when they used cognitive reappraisal strategies in relationship with their teachers and their peers. Female students, on the other hand, adjusted better in relationship with their teachers their peers, and in academics, when using cognitive reappraisal strategies. In school year differences, middle school students who used less of emotional regulation strategies in academics, friendship and student-teacher relations adjusted better in relationship with their peers.

  • In the current College Scholastic Aptitude Test (CSAT), the standardized scoring system is being adopted to adjust te differences of degrees of difficulty between the optional subjects. But it becomes clear that the system has several weak points, some of which are considered to be very serious. In this paper we propose an alternative method, so-called the additive scoring system. It determines the additional points per each subjects, according to the subject mean scores. The proposed method has been simulated using the data of 2005' CSAT, and it turns out that the additive scoring system reduces or remove the troubles caused by the standardized scoring system.

  • An analysis of 87 stroke Patients who were enrolled in 7 hospitals in cities of Pusan, Taegu, Kumi, and Andong from January 1 to May 31, 1998 was conducted using the modified Barthel Index(BI) and the adapted PULSES profile index(PS) to evaluate their function. Patients were examined at the following intervals : Initial assessment, one month after initial, at discharge, and ore month after discharge. The mean BI score of patients initial assessment was 26.32. and that of PS was 17.34. There were statistically significant between initial score and one month after initial (16.61 : p<0.001), at discharge(33.51 : p<0,001), one month after discharge(43,56 : p<0.001). PS scores were also improved significantly(-2.1, -3. 94, and -5.52(p<0.001), and BI score between discharge and one month after discharge wag significant improvement(10.06 : p <0.001) and in PS score(-1,57 : p<0.001). Age and BI scone were significantly associated with the improved in BI score between initial and discharge (T3-T1)(p<0.05). Below age forty and the lower initial BI score showed significantly higher improvement(T3-T1) after physical therapy(p<0.05). Initial BI score, BI score at discharge, and religion were significantly associated with the improvement of BI score between initial and one month after discharge(T4-T1)(p<0.05). The lower initial BI score, the high. BI score at discharge, and the religious showed significantly higher improvement(T4-T1)(p<0.05). BI score at discharge and religion were significantly associated with the improvement of BI score between at discharge and one month after discharge(T4-T3)(p<0.05). The lower BI score at discharge, the religious showed significantly higher improvement(T4-T3)(p<0.05) Initial PS score were significantly associated with the improved in PS score between initial and discharge(T3-T1)(p<0.05). The higher initial PS score showed significantly hier improvement(T3-T1)(p<0.05). Initial PS score, Bi score at discharge, and patient's attitude for physical therapy after discharge were significantly associated with the improvement of PS score between initial and one month after discharge(T4- T1)(p <0.05). The higher initial PS scorer the lower PS score at discharge, patient's positive attitude for physical therapy after discharge showed significantly higher improvement(T4-T1)(p<0.05). PS score at discharge, Patient's attitude for Physical therapy after discharge were significantly associated with the improvement of PS score between discharge and one month after discharge(T4-T3)(p<0.05). The higher PS score at discharge, patient's positive attitude for physical therapy after discharge showed significantly higher improvement(T4-T3)(p<0.05). In conclusion, Initial BI score, BI score at discharge, age, and religion were significantly associated with BI score improvement. initial PS score, BI score discharge, and patient's attitude for physical therapy after discharge were significantly associated with PS score improvement in stroke patients.

  • The purpose of this study was to investigate the effects of on-farm management systems(including the farm size, stocking density of growing-finishing phase, proportion of finisher diet and type of growing-finishing building) and pre-slaughter handling(including the transportation time and loading time) on carcass grade, the incidence of PSE pork, the meat quality score for intra-muscle fat, inter-muscle fat, subcutaneous fat and score for elasticity of market pigs. For this study, 248,787 pigs of 53 different farms were used to establish the pork quality assurance program and to meet the comsumer's need. The results are summarized as follows. 1. The farm size had significant influence on carcass grade, in which showing the higher grade by increasing the farm size. However, the incidence of PSE pork were not significantly differences among the farm size. The meat quality score for intra-muscle fat, inter-muscle fat, subcutaneous fat and score for elasticity of market pigs were not significant influenced by farm size. 2. The stocking density of growing-finishing phase was statistically significant for carcass grade, in which showing the higher grade in mid density group. However, the incidence of PSE pork was higher in high density group. The meat quality score for intra-muscle fat, inter-muscle fat and elasticity of market pigs were greater in mid density groups, but not influenced by stocking density for subcutaneous fat score. 3. The carcass grade and the incidence of PSE pork were not significantly influenced by transportation time. However, transportation time significantly affected the meat quality score, the meat quality score for intra-muscle fat, inter-muscle fat, subcutaneous fat and elasticity of the carcasses were superior in more than 1 hour transportation groups. 4. At any time loading, the carcass grade and PSE incidence were not significantly differences. However, the meat quality score for intra-muscle fat, inter-muscle fat and elasticity of market pigs were superior in before 10 AM groups, but not influenced by loading time for subcutaneous fat score. 5. The proportion of finisher diet had not significant influence on carcass grade, but PSE incidence affected by proportion of finisher diet, 21 percent or more group was higher PSE incidence. The meat quality score for intra-muscle fat and inter-muscle fat of the carcasses were superior in 21 percent or more fed finisher diet groups, but elasticity score of carcass had not influenced by the proportion of finisher diet. 6. The type of growing-finishing building was affected the carcass grade and PSE incidence of the market pigs, carcass grade and PSE incidence were superior in enclosed mechanical ventilation building groups. The meat quality score for intra-muscle fat and inter-muscle fat of the carcasses were not significantly differences by the type of finishing building, but the score of subcutaneous fat and elasticity of carcass were superior in opened natural ventilation building groups. In conclusion, the results of this study suggest that we have more precise on-farm management practice and the knowledge related to pre-slaughter handling skills to reduce the stress and improve the status of welfare of market pigs.
