  • This study aimed to develop SSTPBL (Student-led Simulation with Team and Problem-Based Learning), whichcombines TBL and PBL with a student-led method to strengthen knowledge application, nursing diagnosis ability, and collaboration ability among the core competencies of nurses. Then, SSTPBL was applied to nursing students, and the results were assessed. The data was collected from September 15, 2022, to December 21, 2022, with structured questionnaires and focus group interviews with 51 fourth-year nursing students at a university in A City. The collected data were analyzed using SPSS version 25.0 and topic analysis. As a results, it was effective in simulation experience satisfaction(t = 3.51, p < .01), vSim experience satisfaction(t = 3.50, p < .01), preparation as a prospective nurse(t = 3.73, p < .01), learning self-efficacy(t = 3.87, p < .01), collaborative self-efficacy (t = 4.30, p < .01), problem-solving ability(t = 5.26, p < .01), educational satisfaction(t = 3.54, p < .01), digital health equity(t = 2.18, p < .05). Through the qualitative data's topic analysis, six main topics were derived. The main topics were 'similar to clinical practice', 'difficulty in immersion', 'learning through others', 'learning through self-reflection', 'improving confidence through new experiences' and 'new teaching methods'. Based on the results of this study, it is expected that SSTPBL can be used in various ways as a new training method for prospective nurses in the face of growing clinical practice restrictions after the pandemic.

  • Objectives: We analyzed the correlation between physique and size of the dental arch of college students with normal occlusion. Methods: Ninety-nine college students filled out the prepared questionnaire. The length and width of the dental arch of the students was measured using a plaster model after taking an impression. The data were analyzed using the t-test and correlational analysis. Results: The maxilla arch length was 3.70 mm longer and the inter-molar width of the maxilla was 3.06 mm longer in men (both p<0.01) than in women. Additionally, the mandible was 3.66 mm longer in men as compared to those in the women (p<0.01). As height increased, there was increase in the body weight (α=0.683, p<0.01), maxilla arch length (α=0.373, p<0.01), molar width of the maxilla (α=0.214, p<0.05), and the mandible (α=0.280, p<0.01). The greater the weight increase, the greater the maxillary arch length increase (α=0.392, p<0.01), and the greater the molar width of the maxilla (α=0.336, p<0.01) and mandible (α=0.502, p<0.01) increase. Conclusions: As physical size (both height and weight) increased, the maxillary length and molar width also increased. Based on the results of this study, the cause of malocclusion, form and size of the dental arch, and stable occlusion can be used as basic data.

  • Several risk factors for osteoporosis are known relatively well. Some nutrients are directly or indirectly needed for metabolic processes related to bone. Recently, an increased prevalence of osteoporosis has been reported in patients with hemochromatosis, an iron overload disease. Thus, the aim of this study was to find out if there was any relationship between serum ferritin and T-score of bone mineral density in healthy women. We recruited 1,101 subjects females aged between 39 and 85 years. We measured serum ferritin, glucose tolerance indices, lipid profiles, inflammatory indices, hormones, calcium, alkaline phosphatase. Also, anthropometric, blood pressure, and bone mineral density measurements were performed. T-score was negatively correlated with age (r=-0.425; P<0.01), systolic (r=-0.109; P<0.01) and diastolic (r=-0.093; P<0.01) pressure, follicular stimulation hormone (r=-0.190; P<0.01), alkaline phosphatase (r=-0.235; P<0.01), and serum ferritin (r=-0.090; P<0.05) and positively with body mass index (r=0.050; P=0.01), HDL-cholesterol (r=0.314; P<0.01), and estradiol (r=0.200; P<0.01). After adjustment for age, alkaline phosphatase, body mass index, HDL-cholesterol, estradiol, and follicular stimulation hormone, serum ferritin was independently inversely correlated with T-score (${\beta}$=-0.001; P<0.05). It is possible that an increase of serum ferritin in females be risk to osteoporosis.

  • Methods for mode identification and accurate measurements of the unloaded Q ($Q_0$) of a dielectric-loaded $TE_{01{\delta}}$ mode cavity resonator with HTS endplates are proposed. A resonator with a sapphire rod and $YBa_2Cu_3O_{7-x}$(YBCO) endplates was prepared and its microwave properties were studied at temperatures above 30 K. The $TE_{01{\delta}}$ mode $Q_0$ of the resonator, designed to work as a tunable resonator with variations in the gap distance (s) between the sapphire rod and the top YBCO, was more than 1000000 at s = 0 mm and at 30 K with the resonant frequency of 19.56 GHz. The $TE_{01{\delta}}$ mode $Q_0$ decreases as s increases for s < 2 mm until mode couplings between the $TE_{01{\delta}}$ mode and other modes appeared at s = 2 mm. Significant dependence of the $TE_{01{\delta}}$ mode $Q_0$ on the input and output coupling constants was also observed. Applications of the open-ended $TE_{01{\delta}}$ mode cavity resonator for a tunable resonator with a very high Q as well as a characterization tool for the surface resistance measurements of HTS films are described.

  • This study was performed to evaluate repeated-dose toxicities of CONP01 in Sprague-Dawley rats. CONP01, a new antiarthritic agent was administered orally to rats at dose levels of 0, 125, 500 and 2,000 mg/kg/day for 4 weeks. In present study, there were no dose response changes in mortality, clinical signs, body weight changes, food and water consumption, ophthalmoscopy, organ weights, urine analysis, hematological findings, and biochemical examination of all animals treated with CONP01. Gross and histopathological findings revealed no evidence of specific toxicity related to CONP01. These result suggest that no observed adverse effect level (NOAEL) of CONP01 may be over 2,000 mg/kg in rats.

  • The purpose of this study was to find which spatiotemporal gait parameters gained from stroke patients could be predictive factors for the gait part of Tinetti Performance-Oriented Mobility Assessment (POMA-G). Two hundred forty-six stroke patients were recruited for this study. They participated in two assessments, the POMA-G and computerized spatiotemporal gait analysis. To analyze the relationship between the POMA-G and spatiotemporal parameters, we used Pearson's correlation coefficients. In addition, multiple linear regression analyses (stepwise method) were used to predict the spatiotemporal gait parameters that correlated most with the POMA-G. The results show that the gait velocity (r=.67, p<.01), cadence (r=.66, p<.01), step length of the affected side (r=.49, p<.01), step length of the non-affected side (r=.53, p<.01), swing percentage of the non-affected side (r=.47, p<.01), and single support percentage of the affected side (r=.53, p<.01) as well as the double support percentage of the non-affected side (r=-.42, p<.01) and the step-length asymmetry (r=-.64, p<.01) correlated with POMA-G. The gait velocity, step-length asymmetry, cadence, and single support percentage of the affected side explained 67%, 2%, 2%, and 1% of the variance in the POMA-G, respectively. In conclusion, gait velocity would be the most predictive factor for the POMA-G.

  • This study examined the lifestyle factors, dietary attitudes, food habits, and dietary nutrition intake of college students before and after nutrition education. A total of 44 college students were recruited and a questionnaire survey was conducted. Dietary nutrient consumption was obtained from the one day 24-hr recall. Scores on 'Concerns about health (p<0.05)', 'Regular exercise (p<0.01)', and number of steps (p<0.001) were significantly higher after-training. The dietary attitude (31.3 vs. 33.7, p<0.01) and food habits (53.5 vs. 59.7, p<0.01) were significantly higher after-training. The scores on 'Eating a lot of food that I want to eat is more important than nutrition (p<0.01)', 'I am interested in information on nutrition and health (p<0.01)', 'Have three meals a day (p<0.01)', 'Have breakfast regularly (p<0.01)', 'Drink milk every day (p<0.001)', 'Have fruits every day (p<0.05)', and 'Apply nutrition knowledge to daily life (p<0.001)' were significantly higher after-training. Among the nutrients intakes, the protein (p<0.05), vitamin C (p<0.01), and calcium (p<0.001) were significantly higher after-training. Nutrition education improved the lifestyle factors, dietary attitudes, food habits, and dietary nutrition intakes.

  • To analyze proteins related to antifungal activity, SAR01 strain was isolated from seaweed and identified as Streptomyces sp. from the result of FAME (fatty acid methyl ester) analysis. The isolated strain had antifungal activities against T species of plant pathogenic fungi. Antifungal activity deficient mutant (SAR 535) of Streptomyces sp. SAR01 was induced by gamma radiation $(^{60}Co,\;5kGy)$. By 2 D electrophoresis analysis, 6 protein spots were found in wild strain (SAR01) but these spots disappeared in mutant strain (SAR535). Among them, 5 proteins showed similarities to heat shock protein 70(HSP70), Fe-containing superoxide dismutase II (Fe- SODII), ribosome recycling factor (RRF), 10 kDa chnperonin (GroES) and inorganic pyrophosphatase (PPAse), respectively. It suggested that the above 6 proteins could be closely related to the antifungal activity of Streptomyces sp. SAR01.

  • Strain AP01 was isolated for the biological cypermethrin degradation from soil and sediment in Busan. This strain was identified on the basis of phylogenetic analysis of the 16s rDNA sequence and assigned as Bacillus amyloliquefaciens AP01. AP01 could degrade about 45% of cypermethrin in the mineral medium at $30^{\circ}C$ and 180 rpm for 5 days. Furthermore when 2% glucose was added in the medium, the degradation rate of cypermethrin by strain AP01 was increased upto about 60%. Therefore, AP01 may serve as a promising strain in the bioremediation of soil polluted with cypermethrin.
