There has been insufficient studies on the effect of programming language learning on logical thinking ability. Each study result on the improvement degree and items of logical thinking ability is different according to the object of the study, its method, and the learning subject, which makes the generalization process difficult. Moreover, the necessity of programming language learning seems not proved, because it is not apparent whether the improvement of logical thinking ability is due to the advancement of knowledge or programming language learning. In this study, we instructed educational programming languages to elementary students in 6th grade for 7 hours, investigated its effect on logical-thinking ability by the meta-cognition level, and compared the result with that of computer skill learning. As a result, for Dolittle, LOGO, and Powerpoint learning groups, the logical-thinking ability of high meta-cognition level students has increased with significance, but that of low meta-cognition level students has significantly increased for Dolittle and LOGO groups only. However, regardless of meta-cognition levels, there was no significant difference of logical-thinking ability between all three groups.

Objectives : Urocanase domain containing 1 (UROC1) has never been studied in prior studies on autism spectrum disorders (ASDs). UROC1 causes urocanic aciduria, one of the symptoms of which is mental retardation. The aim of this study was to investigate the association between the UROC1 gene and ASDs in a Korean population. Methods : A total of 258 control and 214 patients with ASD were used as subjects of this study. SNPs selected from UROC1 were genotyped using Illumina Golden-Gate Genotyping assay with VeraCode$^{(R)}$ technology. Statistical analysis was performed using SAS and Plink software. Results : We found no association of the 12 SNPs in the UROC1 gene with ASDs in a Korean population. Conclusion : Our study suggests that the 12 SNPs (11 SNPs and 1 SNP in the intron and 3'UTR region, respectively) in the UROC1 were not associated with ASDs in a Korean population. Further study on the exon region of UROC1 is needed.

With the curriculum revision in 2015, informatics for secondary high schools was designated as mandatory. As a result, there is an increasing interest in programming in elementary and junior high schools as well as in universities. Arduino is one of the famous tools for programming education, and the usefulness of it has been proven through various case studies. However, existing Arduino-based kits have hardware-dependent drawbacks such as complicated wiring, poor scalability, etc. To overcome these problems, we proposed a kit design, which has a module-based structure, can be extended through one common interface, and can be used for learning at various levels. In this paper, we describe the implementation details of FRUTO kit and a software to use it, which satisfies the proposed design criteria. FRUTO kit has been determined in its current form through several design changes, and is under pre-test before launching.

The principal objectives of this study were to evaluate the space, equipment, and institution rate by functional area, and to suggest appropriate types, numbers, and equipment capacity by school foodservice size for optimal employee job performance and efficiency. Data were collected and administered by 263 dietitians who attended elementary and middle schools in Gyeonggi Province, and the data were analyzed using SPSS statistical software. Among a total of 72 respondents who provided usable data, 31 (48.6%) respondents were nutrition teachers and 37 (51.4%) were part-time dietitians. The majority of the respondents reported that their foodservices were self-operating types (94.4%), and 8 meals out of 10 meals provided over a 2-week period were served as normal meals, defined as meals consisting of Bab, Kook, Kimchi, and 3 side dishes (73.6%). The mean kitchen space was $186.25\;m^2$ for 500 meals/day, $269.7\;m^2$ for 501 to 1,000 meals/day, $249.1\;m^2$ for 1001 to 1500 meals/day, and $274.87\;m^2$ for 1,500 or more meals/day. The mean space of functional areas was $11.52\;m^2$ for office, $12.63\;m^2$ for storeroom, $9.55\;m^2$ for receiving area, $27.23\;m^2$ for pre-preparation area, $149.9\;m^2$ for cooking area, $18.33\;m^2$ for assembly/service area, $45.50\;m^2$ for dishwashing area, and $17.20\;m^2$ for locker room. Only two pre-preparation and cooking spaces increased significantly with increasing size of school foodservice (p<0.05). Office, cooking area, and locker room were allocated in all foodservices. However, the pre-preparation area (68.7%), receiving area (56.5%), assembly/service area (38.1%), and dishwashing area (37.7%) were lowly installed in the surveyed facilities. Through a focus group meeting discussing the results of this study, appropriate equipment and its dimensions were suggested according to functional areas and foodservice scales. Future studies will be necessary to allocate the appropriate space by functional area with the proposed equipment requirements for optimally efficient decision making in equipment purchasing.

Objectives : The region of chromosome 5p14 is known to be associated with autism spectrum disorder (ASD). The cadherin9 (CDH9) and cadherin10 (CDH10) genes are located in the region of chromosome 5p14 and reported to be associated with ASD in the Caucasian population. We performed an association study to identify if single nucleotide polymorphisms (SNPs) located on the CDH9 and CDH10 genes are associated in the Korean population. Methods : Genomic DNA was extracted from the blood of 214 patients with ASD and 258 controls. SNPs selected from two genes were genotyped using an Illumina Golden-Gate Genotyping assay with VeraCode technology. Statistical analysis was performed using SAS and Plink software. Results : All controls and ASD patients were in Hardy-Weinberg equilibrium. In the results of logistic regression analyses for the genotype model and the chi-square test for the allele model, we found that SNPs on the CDH9 and CDH10 genes were not associated with ASD. Conclusion : Our data suggests that the CDH9 and CDH10 genes are not associated with ASD in the Korean population.

Objectives ： Autism spectrum disorder (ASD) is a neurodevelopmental disorder that is characterized by abnormalities of social functioning, communication and behavior. The association of the 7q21-34 region with ASD has been reported. The DLX6 gene, which is located at the 7q22 region, is one of the positional and functional candidate genes for ASD. We found that there is no association between DLX6 polymorphisms and ASD in the Korean male population. Methods ： We selected three single nucleotide polymorphisms (SNPs) that might be implicated in the change of the DLX6 gene expression. The genomic DNA was collected from the venous blood of 147 male controls and 179 male patients with ASD. The genotypes of the selected SNPs were determined using the Illumina GoldenGate assay, and the statistical analyses were performed using HapAnalyzer software and SAS Enterprise. Results ： We found no association of the three SNPs in the DLX6 gene with ASD in the Korean male population. Conclusion ： Our study suggests that the three SNPs in the DLX6 gene are not associated with ASD, and we need to analyze the previously reported regions for their associations with ASD.
