When it comes to the value of modern education, teachers are required to perform the role of a helper to promote interaction between learners, the role of a manager to facilitate smooth learning, and the role of a guide who has expert knowledge in the learning contents. Therefore, this study investigated what kind of learner-centered teaching methods there are, which require teachers to perform the roles of helper, manager, and guide, and conducted a pedagogical research on coding education to explore class models for self-directed learning. Subsequently, a class model was proposed by applying the flipped learning and havruta learning to a coding class. In this study, the learner-centered education methods of flipped learning and havruta method were applied to constructing a coding class as a university general education course. The feature of this class is that it enables dynamic interaction between teachers and learners as well as active interaction between leaners in a classroom instruction. After applying the proposed method to the actual class and analyzing it, the students taught using suggested method were more positively assessed in learning interest than those taught using a traditional method. And that in academic achievement as well, suggested method was more effective.

This article delineates a rationale behind the necessity of programs reinforcement for Korean national insurance system to improve overall Korean health care practice. Today, Korean central and local government health care programs provides a 10% of total health care supplies, whereas major OECD countries supply from 60 to 90% of the total services. Even in the United States, Federal or state government supplies a 20 % of all services supplied. It is urged that health privatization policies should not at any circumstance be materialized. Instead, the national government should consider to increase national and public medical centers in cities and to improve public health care quality.

Background: Inhalation induction with desflurane can cause airway irritability and sympathetic stimulation. The aim of this study was to investigate whether lidocaine and fentanyl could reduce these unwanted reactions. Methods: Seventy-five patients who had premedication with midazolam were randomly allocated to one of three groups to receive intravenous saline (S group), lidocaine 1.5 mg/kg (L group), fentanyl 1 μg/kg (F group), respectively, before tidal volume induction with desflurane in oxygen and nitrous oxide. We recorded airway irritability such as cough, apnea, laryngospasm and excitatory movement and hemodynamic changes. Results: Airway irritability was not significantly different between the groups. In F group, mean blood pressure at LOC ver and LOC BIS and heart rate at LOC ver, LOC BIS and just before intubation were lower than those of S group (P<0.05). Other results were not significantly different. Conclusions: The results of the study showed that intravenous fentanyl and lidocaine had no beneficial effects to reduce airway irritability, but intravenous fentanyl could significantly reduce hemodynamic stimulation during inhalation induction with desflurane in the patients who were premedicated with midazolam.

Anemia, defined as a reduction in the hemoglobin concentration of blood, is common in diabetes mellitus (DM) patients, can be potentially caused by diabetes complications such as nephropathy. Recent research suggests that diabetes mellitus (DM) itself may be a major risk factor of anemia. However, there are few Korean studies on the relationship between diabetes mellitus (DM) and anemia. This study was performed to investigate the association between anemia and diabetes mellitus (DM) in Korean adults. A total of 10,151 Korean adults over aged 19 years (4,422 male, 5,729 female) were selected from the participants of the Korean National Health and Nutrition Examination Survey VI (KNHANES VI). Korean adults with anemia had a higher prevalence of diabetes mellitus (DM) than the normal adults (11.4% vs. 30.4% in male, 8.8% vs. 9.4% in female). The unadjusted odds ratio (OR) for anemia was greater in adults with DM than in normal male (OR=3.28; 95% CI: 2.27∼4.73). After adjusting for other risk factors including age, education, family income, smoking, drinking, and menstrual status, anemia and diabetes were not associated (OR=1.33; 95% CI: 0.84∼ 2.09). Similarly, there was no association between anemia and diabetes in female. In conclusion, this study shows that the prevalence of anemia is similar in diabetic and non-diabetic Korean adults after adjusting for multiple risk factors. Further research is required to elucidate the mechanism of anemia caused as a con-sequence of diabetes mellitus (DM).

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.

Silica encapsulated ZnSe quantum dots (QDs) were prepared by employing two microemulsion systems: AOT/water/cyclohexane microemulsions containing ZnSe quantum dots with NP5/water/cyclohexane microemulsions containing tetraethylorthosilicate (TEOS). Using this method, cubic zinc blende nanoparticles (3 nm in diameter) were synthesized and encapsulated by silica nanoparticles (20 nm in diameter). The temperature dependence of photoluminescence (PL) for silica-encapsulated ZnSe QDs was investigated to evaluate this material as a temperature sensor media. The fluorescence emission intensity of silica-encapsulated ZnSe nanoparticles (NPs) was decreased with an increase of ambient temperature over the range from 30 ℃ to 60 ℃ and a linear relationship between the temperature and the emission intensity was observed. In addition, the temperature dependence of PL intensity for silica-encapsulated ZnSe NPs showed a reversible pattern on ambient temperature. A reversible temperature dependence of the luminescence combined with its insensitivity toward quenching by oxygen due to silica coating established this material as an attractive media for temperature sensor applications.

In Internet of Things (IoT) era, more diverse types of information are collected and the environment of information usage, distribution, and processing is changing. Recently, there have been a growing number of cases involving breach and infringement of personal information in IoT services, for examples, including data breach incidents of Web cam service or drone and hacking cases of smart connected car or individual monitoring service. With the evolution of IoT, concerns on personal information protection has become a crucial issue and thus the risk analysis and management method of personal information should be systematically prepared. This study shows risk factors in IoT regarding possible breach of personal information and infringement of privacy. We propose “a risk analysis framework of protecting personal information in IoT environments” consisting of asset (personal information-type and sensitivity) subject to risk, threats of infringement (device, network, and server points), and social impact caused from the privacy incident. To verify this proposed framework, we conducted risk analysis of IoT services (smart communication device, connected car, smart healthcare, smart home, and smart infra) using this framework. Based on the analysis results, we identified the level of risk to personal information in IoT services and suggested measures to protect personal information and appropriately use it.
