The objective of this study was to develop and evaluate the construct validity of a Nutrition Quotient (NQ) for children. In a previous report (Kang, et al., 2012), the food behavior checklist for children's NQ, consisting of 19 items, was grouped into a 5-factor structure according to the exploratory factor analysis: balance, diversity, moderation, regularity, and practice. In this study, the construct validity of the NQ was assessed using a confirmatory factor analysis. Elementary school students (n = 1,393) from six large cities completed the NQ test. Indicator tests suggested an adequate model fit (goodness of fit index = 0.9613; adjusted GFI = 0.95; standardized root mean square residual = 0.0464; chi-square test statistics of < 0.001 p-value, 82.1), and item loadings were significant for all subscales (p < 0.05). The standardized path coefficients were used as the weights of the items. The NQ and the 5 factor scores of the student were calculated by the obtained weights of the questionnaire items. Logistic regression was applied to find the significant factors in order to affect a specific nutrient status. The receiver operation characteristic curve analyses were performed in order to find diagnostic cut-off points of the five factors. The food behavior checklist for children's NQ would be a handy and suitable instrument for evaluating dietary behaviors of Korean children.

The purpose of this study was to investigate the correlation between high school students' observation ability quotient and changes in their stress hormones while observing fruits. This experimental study was performed with 29 first-year female high school students in a metropolitan city. In order to measure the observation ability quotient, an appropriate scientific observation program was developed. In observation program, the subjects carried out observations in an open and autonomous environment and recorded their observations. Their saliva samples were extracted before and after the task so as to analyze the amount of the secreted hormone. Also, their observation ability was measured using the quotient equation of observation ability. And then, in order to investigate the relationship between the observation ability and the cortisol hormone, a correlation analysis was performed. The main results are as follows: First, the amount of learner's hormone secreted during the experiment decreased in overall after the free observation. And the observation ability quotient turned out to be significantly correlated to the cortisol hormone.

The objectives of this study were to assess food behavior and nutritional status of preschool children by using the Nutrition Quotient (NQ) for children and children's growth index. The subjects for this study were 424, 5-year old children, who enrolled in child-care centers (n = 219) and kindergartens (n = 205) in Nowon-gu, Seoul. The NQ was examined by NQ questionnaire which consisted of 19 food behavior checklist items. Their items were grouped into 5 categories: balance, diversity, moderation, regularity, and practice. Children's anthropometric measurements were performed by using InBody J05. All data were statistically analyzed by SAS 9.3 and significant difference was evaluated by Student's t-test and ${\chi}^2$-test. The rates of overweight and obesity for subjects were 11.1% and 3.3%, respectively. Total NQ score of the subjects was 65.1, which was within medium grade. The NQ score of kindergartens (66.1) was higher than that of child-care center (64.2), showing significant difference by institution type. In addition, the NQ score of obesity was significantly lower than that of normal weight subjects. The scores of balance (p < 0.05) and regularity factor (p < 0.001) were higher in kindergarten compared to child-care center. Particularly, the frequency of consumption of white milk and Ramyeon was higher (p < 0.001) and lower (p < 0.05) respectively in kindergarten compared to child-care center. Frequencies of meal regularity (P < 0.01) and breakfast eating (p < 0.001) were also higher in kindergarten compared to child-care center. These results indicate that kindergarten's children had better eating habits than those of child-care center. Overall analysis of items for food behavior checklists implies that children in Nowon-gu are short of vegetables consumption. Therefore, children and their parents need proper nutrition education and counseling to correct their eating habits and to improve their nutritional status.

This study investigated the nutrition education realities and nutrition status of children in community child centers, by analyzing the status of nutrition education, nutrition quotient (NQ), and the level of maintaining dietary guidelines. The subjects were 173 children from grades 1 to 6, enrolled in community child centers, Jinju, Kyungnam. The NQ was examined by a questionnaire, which was a checklist of 19 food behavior items. The distribution of scores (out of 100) in the nutrition quotient were as follows: total score of NQ was 59.4, balance 56.6, diversity 60.6, moderation 65.6, regularity 60.9, and practice 56.7. Nutrition quotient was higher in the higher graders due to significant differences in the area of variety. The level of maintaining dietary guidelines was higher in girls, especially in the area 'eat politely with family', and higher amongst the upper graders in the area 'have safe snack wisely'. To improve the eating habits and nutritional status of the children in community child centers, their nutritional state should be checked with regular and systematic education, and their nutritional management should be pursued continuously. Since the assessment of the eating behaviors and the nutritional state of children is important at home as well as in schools and community child centers, nutritional education should be further extended to the parents and their care givers. This study can be implemented as basic material for the nutritional education of children, to minimize the dangers of malnutrition and to help build up the right eating habits amongst children in community child centers.

Background and Objectives : The managements of unilateral vocal cord palsy include type Ⅰ thyroplasty and arytenoid adduction. One type operation has been shown no satisfactory effect. We evaluated preoperative and postoperative speech of unilateral vocal cord palsy patients who received combined operation of type Ⅰ thyroplasty and arytenoid adduction to help for the management plan of unilateral vocal cord palsy patients. Materials and Methods : We reviewed the postoperative results and complication of 17 surgically treated patients of unilateral vocal cord palsy at Severance hospital from Nov. 1996 to Dec. 1997 retrospectively. They were received combined operation of type Ⅰ thyroplasty and arytenoid adduction. Their pre and post-operative speech were analyzed with MDVP(Multi-Dimension-Voice analysis Program) of CSL(Computerized Speech Lab). Results : After the operation, MPT(Maximal Phonation Time) was increased and MFR(Mean Flow Rate) was decreased in all patients. NHR(Noise to Harmonic Ratio) and VTI(Voice Turbulence Index) were decreased : liner, RAP(Relative Average Perturbation Quotient), PPQ(Pitch Period Perturbation Quotient), sPPQ(smoothed Pitch Period Perturbation Quotient), vFo(fundamental frequency Variation) were decreased : Shimmer, APQ(Amplitude Perturbation Quotient), sAPQ(Smoothed Amplitude Perturbation Qoutient), vAm(Peak Amplitude Variation) were decreased in all the patients. Conclusions : In unilateral vocal cord pals), combined operation of type Ⅰ thyroplasty and arytenoid adduction could obtain satisfactory postoperative voice. MDVP has many parameters and good method for evaluation of voice surgery.

Purpose : The purpose of this study was to investigate the differences in social quotient and sensory processing function between completed-toileting and incomplete-toileting children with autism spectrum disorder (ASD). We aims to provide a basis for the training of children with autism spectrum disorders. Methods : The subjects of this research were children with ASD, aged from 4 to 7, receiving sensory integration therapy at the H-Child Development Research Center in Busan, South Korea. After recruiting 30 parents who had children with ASD, we interviewed them and we divided their children into completed-toileting group and incomplete-toileting group based on the past researches. We assessed them using the Social Maturity Scale and Sensory Profile. Spearman correlation was used to analyze between the sensory processing score and social quotient. Mann-Whitney U test was used to compare the Sensory Profile scores of the two groups. Results : The social quotient was correlated with the sensory processing score in the most of component as for auditory processing, vestibular processing, touch processing, multisensory processing, orosensory processing, except for visual processing. The groups of completed-toileting and incomplete-toileting group showed statistically significant intergroup difference in sensory seeking, emotional reactive, oral-sensory sensitivity, and inattention/distractibility in the sensory factor region. No statistically significant difference from intergroup was observed in any modulation areas, nor in behavioral & emotional response domains. Conclusion : A significant intergroup difference was observed in the most of sensory processing areas, except for modulation areas and behavioral & emotional response domains. The result revealed that toileting is significantly correlated with sensory processing. Therefore, this study suggests that the sensory processing function should be considered in the toilet training of children with ASD.
