On this Study, it conducts the Standards investigation about air leakage of Buildings for performance improvement of Smoke control in Fire. In domestic standards, it is incomplete the Criteria standards of air leakage. Therefore it is considered that won’t limit the smoke spread due to stack effect. But in the case of the United States, it conducts the Hot smoke air-Leakage test and it consider that can prevent the Smoke Spread in Compartment.

This study randomly chose 10 humanity high schools, which are located in Busan and KyoungNam province. We then examined the recognition rate of physical therapy among 378 teachers who were and still are working in the schools. 1. The recognition grade of physical therapeutics between men and women was significantly different with results of 80.7% of men and 69.7% of women(p<0.05). In the case of experiencing physical therapy, 83.6% of people said they knew the physical therapeutics and in the case of the opposite side, the result was also significantly different with a result of 67.8%(p<0.05). 2. We ranked the people on how much they knew about the physical therapeutics among men and women. With men, the actual experience of physical therapeutic came before what they heard from other people. In the case of women, what they heard from other people came first and the actual experience of physical therapeutic came after. According to the public information from Inje University, the recognition grade is recorded in the 3rd grade department as 21.5% while in the case of experiencing treatment from a physical therapist, the result was 39.1%. In the other department (the 1st grade department), what men and women heard from mass media was recorded at 17.5% and what they heard from other people, it was recorded at 33.8%(p<0.05). 3. The research about the recognition of academic ability of being a physical therapist was that 55.6% of teachers thought that 3-year-college was the best, which made the results different from the recognition grade of the experience of education(p<0.05). 4. In the recognition grade of physical therapeutics, there were significantly differences from 50.2% of men and 45.2% of women were expecting about 1mil ion won to 1.99million won. In case of 25.2% of people who have experience less than 15years at work, they expected about 2million to 2.99million won. The figures were higher than 10.1% of people who have experiences over 15years. About the recognition grade of physical therapists social level in the future is 48.8% of people who had experienced of physical therapy and 63.8% of people who never had experienced of it said it would be better in the future. From these results, the recognition about physical therapeutics and the view of its social status are optimistic and they know well about the level of academic ability of physical therapists. On the other hand, most teachers don't know exactly about physical therapists work. So we have to inform them aggressively for enhancing the recognition of physical therapy because high school students are well affected by their teachers when they face their future or major in university.

Coprinopsis cinerea was employed to investigate the fungal response to gravity. Mycelium growth revealed a consistent growth pattern, irrespective of the direction of gravity (i.e., horizontal vs. perpendicular). However, the fruiting body grew in the direction opposite to that of gravity once the primordia had formed. For the proteomic analysis, only curved-stem samples were used. Fifty-one proteins were identified and classified into 13 groups according to function. The major functional groups were hydrolases and transferases (16%), signal transduction (15%), oxidoreductases and isomerases (11%), carbohydrate metabolism (9%), and transport (5%). To the best of our knowledge, this is the first report on a proteomic approach to evaluate the molecular response of C. cinerea to gravity.

Purpose: Infection remains the main cause of morbidity and mortality in liver transplantation (LT) recipients; however infection is notoriously difficult to diagnose because its usual signs and symptoms of infection may be masked or absent. This study comprises an analysis of bacterial infections in the early period after LT. Methods: This is a study of 129 adults who underwent LT from January 2013 to December 2013, and it includes patients who were followed daily from the day of transplantation to 1-week posttransplantation using bacteriological cultures of blood, urine, sputum, and drained ascites. Results: The following factors were significantly different between the positive and negative culture groups: living donor LT vs. deceased donor LT (odds ratio [OR], 3.269; P = 0.003), model for end-stage liver disease score (OR, 4.364; P < 0.001), and Child-Pugh classification (P = 0.007). Neither positive culture nor negative culture was associated with infection within 4 weeks of surgery (P = 0.03), and most events were due to surgical complications (75%). Conclusion: Since the full effect of immunosuppression is not yet present during the first month after LT, we suggest that the number of bacterial culture test could be reduced such that they are performed every other day depending on patient’s situation

Background/Aims: We evaluated changes in the ascending aorta dimension post-transcatheter aortic valve replacement (TAVR) in bicuspid aortic valve (BiAV) and tricuspid aortic valve (TAV) patients. Methods: Patients with severe aortic stenosis undergoing TAVR at Seoul National University Hospital were consecutively recruited. Patients with less than 12 months’ follow-up and/or with an ascending aorta size larger than 50 mm were excluded. The ascending aorta size was measured on a parasternal long axis view using transthoracic echocardiography. Results: Among the 67 patients who were included (age: 76.5 ± 6.5 years; male: 52.2%; AV area: 0.67 ± 0.15 cm2), 19 (28.4%) had BiAV; 48 (71.6%) had TAV. The median (interquartile ranges) follow-up duration was 398 days (361 to 451). BiAV patients were younger (73.2 ± 7.2 vs. 77.8 ± 5.8, p = 0.008), and had lower incidences of chronic renal disease (5.3% vs. 35.4%, p = 0.014) and history of coronary intervention (15.8% vs. 50.0%, p = 0.013), than TAV patients. On pre-procedural echocardiography, the ascending aorta dimensions in BiAV patients were larger than those in TAV patients (40.5 ± 3.8 mm vs. 35.9 ± 4.2 mm, p < 0.005). The ascending aorta dimension changed minimally during follow-up; post-TAVR, the ascending aorta’s growth rate was -0.11 ± 1.9 and 0.26 ± 1.8 mm/yr in patients with BiAV and TAV, respectively (p = 0.50). Progression of the ascending aorta’s dimension post- TAVR was not clinically significant in BiAV patients. Conclusions: The concern about the progression of aortopathy in BiAV patients post-TAVR may not be a clinical issue. This should be confirmed in studies with a larger population and with a longer follow-up duration.

Cryptococcal pneumonia usually occurs in immunocompromised patients with malignancy, acquired immune deficiency syndrome, organ transplantations, immunosuppressive chemotherapies, catheter insertion, or dialysis. It can be diagnosed by gaining tissues in lung parenchyma or detecting antigen in blood or bronchoalveolar lavage fluid. Here we report an immunocompetent 32-year-old male patient with diabetes mellitus diagnosed with cryptococcal pneumonia after a ultrasound-guided percutaneous supraclavicular lymph node core needle biopsy. We treated him with fluconazole at 400 mg/day for 9 months according to the guideline. This is the first case that cryptococcal pneumonia was diagnosed from a percutaneous lymph node biopsy in South Korea.

Background/Aims: The efficacies of lopinavir-ritonavir or hydroxychloroquine remain to be determined in patients with coronavirus disease 2019 (COVID-19). To compare the virological and clinical responses to lopinavir-ritonavir and hydroxychloroquine treatment in COVID-19 patients. Methods: This retrospective cohort study included patients with COVID-19 treated with lopinavir-ritonavir or hydroxychloroquine at a single center in Korea from February 17 to March 31, 2020. Patients treated with lopinavir-ritonavir and hydroxychloroquine concurrently and those treated with lopinavir-ritonavir or hydroxychloroquine for less than 7 days were excluded. Time to negative conversion of viral RNA, time to clinical improvement, and safety outcomes were assessed after 6 weeks of follow-up. Results: Of 65 patients (mean age, 64.3 years; 25 men [38.5%]), 31 were treated with lopinavir-ritonavir and 34 were treated with hydroxychloroquine. The median duration of symptoms before treatment was 7 days and 26 patients (40%) required oxygen support at baseline. Patients treated with lopinavir-ritonavir had a significantly shorter time to negative conversion of viral RNA than those treated with hydroxychloroquine (median, 21 days vs. 28 days). Treatment with lopinavir-ritonavir (adjusted hazard ratio [aHR], 2.28; 95% confidence interval [CI], 1.24 to 4.21) and younger age (aHR, 2.64; 95% CI 1.43 to 4.87) was associated with negative conversion of viral RNA. There was no significant difference in time to clinical improvement between lopinavir-ritonavir- and hydroxychloroquine-treated patients (median, 18 days vs. 21 days). Lymphopenia and hyperbilirubinemia were more frequent in lopinavir-ritonavir-treated patients compared with hydroxychloroquine-treated patients. Conclusions: Lopinavir-ritonavir was associated with more rapid viral clearance than hydroxychloroquine in mild to moderate COVID-19, despite comparable clinical responses. These findings should be confirmed in randomized, controlled trials.
