Background: The study aim was to investigate the level of restrictions on daily life and concern about economic damage caused by the coronavirus disease 2019 (COVID-19) pandemic and analyze the effects on daily life satisfaction. Methods: 2021 Community Health Survey data of 229,242 individuals were analyzed. Such factors as restrictions on daily life, changes in physical activity and instant food consumption and concern about economic damage were selected as variables for analysis, as they were presumed to impact daily life satisfaction during the COVID-19 pandemic. Results: The odds ratio for poor daily life satisfaction was 1.88 (95% confidence interval [CI], 1.83–1.94) for those who experienced moderate restrictions and 3.48 (95% CI, 3.31–3.65) for those who experienced severe restrictions, compared to those who had no restrictions in daily life. The group with reduced physical activity had an odds ratio of 1.29 (95% CI, 1.26–1.33) for poor daily life satisfaction compared to the group with no change. The group with increased consumption of instant foods had an odds ratio of 1.23 (95% CI, 1.18–1.28) for poor daily life satisfaction compared to the group without such an increase. Regarding the economic damage caused by the COVID-19 pandemic, the odds ratio for experiencing negative daily life satisfaction was 1.17 (95% CI, 1.10–1.24) for those with moderate concern and 1.43 (95% CI, 1.37–1.50) for those with severe concern, compared to those who were not worried. Conclusion The results of this study could be helpful in planning public health and medical policies for population groups that are relatively vulnerable to decreased daily life satisfaction.

OBJECTIVES: The aim of this study was to develop the computerized Comprehensive Learning Test-Reading (CLT-R) to evaluate the cognitive processes and achievements related to their basic reading ability and identify dyslexia in children and adolescents in South Korea. We also obtained the normative data and evaluated the reliability and validity of the test. METHODS: We developed the CLT-R, including the word attack/nonword decoding, paragraph reading, sound blending, nonword repetition, rapid automatized naming, letter-sound matching, visual attention, orthography awareness, and digit span tests, for the purpose of diagnosing dyslexia. We investigated the reliability and validity of the tests and gathered the normative data from 399 subjects (male 48.9%), aged 5-14 years, from the last grade in kindergarten to middle school, dwelling in Seoul and Gyeonggi Province, South Korea. RESULTS: No statistical differences were observed between the means of the tests and retests of the CAT. The mean of the correlation coefficient of the test-retest scores was 0.85. According to the construct validity test calculated by principal constant analysis using the oblique rotation method, 4 factors explained 70.0% of the cumulative variances. In addition, the normative data were obtained for all of the CLT-R subtests. CONCLUSION: The computerized CLT-R can be used as a reliable and valid tool to evaluate the reading achievement and reading related cognitive process in Korean children and adolescents in schools, clinics, and research institutes.

OBJECTIVES: This study was conducted in order to develop a computerized test to measure the level of mathematic achievement and related cognitive functions in children and adolescents in South Korea. METHODS: The computerized Comprehensive Learning Test-Mathematic (CLT-M) consists of the whole number computation test, enumeration of dot group test, number line estimation test, numeral comparing test (magnitude/distance), rapid automatized naming test, digit span test, and working memory test. To obtain the necessary data and to investigate the reliability and validity of this test, 399 children and adolescents from kindergarten to middle school were recruited. RESULTS: The internal consistency reliability of the CLT-M was high (Cronbach's alpha=0.76). Four factors explained 66.4% of the cumulative variances. In addition, the data for all of the CLT-M subtests were obtained. CONCLUSION: The computerized CLT-M can be used as a reliable and valid tool to evaluate the level of mathematical achievement and associated cognitive functions in Korean children and adolescents. This test can also be helpful to detect mathematical learning disabilities, including specific learning disorder with impairment in mathematics, in Korea.

BACKGROUND: Bleeding can be a problem in wound debridement. In search for an effective hemostatic agent, we experimented with a chitosan film combined with the recombinant human epidermal growth factor (rh-EGF), hypothesizing that it would achieve effective hemostasis and simultaneously enhance arterial healing. METHODS: Forty-eight Sprague-Dawley rats were used, and 96 puncture wounds were made. The wounds were divided into the following four groups: treated with sterile gauze, treated with gelatin sponge, treated with chitosan, and treated with chitosan combined with rh-EGF. Immediate hemostasis was evaluated, and arterial healing was observed histologically. RESULTS: Groups B, C, and D showed a significant rate of immediate hemostasis as compared to group A (P<0.05), but there were no significant differences among groups B, C, and D. Histologically, only group D showed good continuity of the vessel wall after 1 week. It was the only group to show smooth muscle cell nuclei of the vessel wall. CONCLUSIONS: We observed that chitosan has an effective hemostatic potential and the mix of rh-EGF and chitosan does not interfere with chitosan's hemostatic capabilities. We also identified enhanced healing of vessel walls when rh-EGF was added to chitosan. Further research based on these positive findings is needed to evaluate the potential use of this combination on difficult wounds like chronic diabetic ulcerations.
