This study aims to develop an index of food security in order to assess food security status in Korea and to evaluate reliability and validity of the index. The index of food security was developed based on the US Household Food Security Survey Module (US-HFSS). After the US-HFSS was translated and back-translated, it was evaluated and modified by a focus interview for experts. The developed Korean Household Food Security Survey Module (K-HFSS) was tested by cognitive interviews and a pretest for general community population to assess its application for Korean population. For the reliability and validity of K-HFSS, the survey was conducted with 300 adults aged 40 years or more living in a rural community and 212 infants and toddlers living in an urban community. The reliability was assessed by Cronbach' alpha and the validity was evaluated by content validity, construct validity, and criterion-related validity. The questionnaire items of K-HFSS were partly modified, accounting for Korean social and cultural backgrounds and adapted by general community population. The reliability was relatively high, showing Cronbach' alpha coefficients ranged from 0.80 (for adults) to 0.87 (for infants and toddlers). The content and construct validities were all acceptable. The result of criterion-related validity showed that food security status was significantly related to the household income level. In conclusion, the K-HFSS would be used as a reliable and valid instrument to assess food security status in parts of the Korean population.

Purpose: The purpose of this study was to validate the Korean version of the TNO-AZL Preschool Children Quality of Life (TAPQOL) questionnaire for children aged 18-60 months. Methods: The participants were 223 mothers of healthy children from nurseries and kindergartens, and 54 mothers of hospitalized children from a university children's hospital in Korea. Data were collected in 2011. Principal component factor analysis and known-groups method were used to confirm construct validity, and internal consistency was used to determine reliability. Results: According to the factor analysis, 11 factors with an eigenvalue over 1 were extracted, and these factors explained 73.5% of the variance. All dimensions except two had Cronbach's alpha coefficients greater than .7. The mean TAPQOL scores of the hospitalized group were significantly lower than those of the healthy group (p=.001) for all four functions (physical, emotional, social, and cognitive). Conclusion: The TAPQOL showed acceptable validity and reliability, and can be used to measure children's health-related quality of life in Korea, and can be considered for use in other Asian countries.

The purpose of this study was to evaluate the validity and reliability of the Penn Interactive Peer Play Scale (PIPPS) for Korean young children, with a special confirmative factor analysis. The participants were composed of 435 5-to 6-year-old children and their parents, and 42 teachers. The instruments included the 32-item exploratory PIPPS (Choi & Shin, 2008), the Preschool Behavior Questionnaire (PBQ; Park, 1992), and the PIPPS on parental reporting. The PIPPS was confirmed, and supported the following constructs resulting in the investigation of 3 factors, 'play disruption', 'play interaction', and 'play disconnection', along with 30 items similar to the PIPPS (2008). Inter-correlations between the sub-factors of PIPPS with those of criterion measures were validated by ratings from the PBQ and the parent version of the PIPPS. The reliability coefficients of the sub-factors of the PIPPS ranged from .85 to .92. In conclusion, 3 factor structure of the PIPPS was appropriate to represent the interactive peer play of Korean young children.

Purpose: This study was done to evaluate the validity of the Korean - Child Development Review in screening children with developmental risks. Method: The participants in the study were 172 children aged 6-75 months old and their parents. Data were collected by questionnaire or interview. Korean Denver II and Bayley test were administered with K-CDR for validation of children who were referred for developmental assessment at D University Hospital or public health center. The data were analyzed using correlation, $X^2$ test, and cross tab analysis. Results: There was a significant relationship between the K-CDR and Korean Denver II. The correlation coefficients were .42 to .61 by developmental sector. The sensitivity and specificity of K- CDR were .84 and .66 respectively when "abnormal" with MDI of Bayley test defined as lower than 85 the score which was used as a diagnosis of developmental delay. The responses to 6 questions for parents showed significant differences according to 3 groups by developmental state. Parents of children in the developmental disability group more frequently checked problems from the 26 problem checklist about their children's development and behavior. Conclusion: The results show that K-CDR is valid and has good sensitivity and moderate specificity in screening developmental delay.

During a military service, noise has unusual characteristics, and constitutes a serious hazard to hearing of military servicemen. The purpose of this study is to understand the use of hearing protection and to assess the safety effects of hearing protection by using a ear plug in military. A total of 208(the army : 101, an air force : 107) serviceman were studied utilizing a questionnaire to know how many serviceman use the hearing protection and a total of 202(the army : 110, an air force : 92) serviceman were also studied using a ear fit validation device to assess the safety effects of hearing protection by using a ear plug. The results showed that the army have low used of hearing protection than an air force because of the low frequency of the noise exposure in the army. Personal attenuation rate was increased with 8 dB after fitting education. Therefore, it is recommended that use of proper hearing protection and fitting education was more suitable for military servicemen who were being exposed of the noise in domestic military.
