연구배경: COPD에서 보이는 호흡곤란의 주된 원인이 폐의 과팽창이고 이 과팽창을 치료하는 것이 호흡곤란의 향상에 중요한 것으로 밝혀지고 있다. 그러나 FEV1, FVC만으로는 호흡곤란의 정도와 과팽창을 정확히 측정할 수 없다. 따라서 단순 흉부 방사선에서 관찰되는 폐의 과팽창의 정도와 고해상도흉부 단층촬영에서 폐기종의 정도가 호흡곤란을 객관적으로 알 수 있는 지표가 되는 지를 알아보고자 하였다. 방법: COPD로 진단 받은 50명(평균 연령 69세, 남자 47명, 여자 3명)을 대상으로 하였다. 폐의 종축, 흉골 뒤 공간, 횡격막의 높이를 각각 측정하여 총 0에서부터 3까지로 폐의 과팽창 정도(chest score)를 측정하였고, 고해상도 흉부단층 촬영에서 폐기종의 정도(HRCT score)를 구하여 이를 환자의 호흡곤란의 정도 및 폐용적 검사를 비롯한 폐기능 검사와의 상관관계를 구하였다. 결과: 호흡곤란의 지수(Borg scale)는 폐기능 검사의 지표인 FVC, FEV1, FEV1/FVC, RV, RV/TLC, DLCO와 유의한 상관관계가 관찰되었다. Borg scale은 HRCT score와 상관관계가 있었으나, chest score와는 상관관계가 없었다. 그리고 Borg scale은 체질량 지수와 역 상관관계가 있었다. 결론: 고해상도 흉부 단층촬영의 폐기종의 정도는 COPD 환자에서 호흡곤란의 정도를 알 수 있는 객관적 지표가 될 수 있다. Background: A lung hyperinflation, or air trapping, caused by expiratory flow-limitation contributes to dyspnea in patients with chronic obstructive pulmonary disease (COPD). Forced expiratory volume in 1 second (FEV1) has served as an important diagnostic measurement of COPD, but does not correlate with patient-centered outcomes such as dyspnea. Therefore, this study was performed to investigate the role of radiologic quantity in evaluating the dyspnea in patients with COPD by measuring lung hyperinflation in chest x-ray and high resolution chest tomography (HRCT). Methods: Fifty patients with COPD were enrolled in this study. Their subjective dyspnea score (modified Borg scale dyspnea index), spirometry, and lung volume were measured. Simultaneous hyperinflations of chest x-ray score (chest score) and degree of emphysema of HRCT (HRCT score) were measured. The chest score were composed of lung length, retrosternal space width, and height of the arc of the diaphragm and HRCT score were composed of severity and extent of emphysema. Results: The mean age of patients was 69 years old and their mean FEV1 was 51.7%. The Borg score significantly correlated with parameters of spirometry and lung volume, including FVC, FEV1, FEV1/FVC, RV, RV/TLC, and DLCO. The Borg score correlated well with HRCT score, but did not correlate with chest score. Also, the Borg scale correlates inversely with body mass index. Conclusion: The quantity of emphysema on chest HRCT may serve as an objective marker of dyspnea in patients with COPD.

A new trend in the post COVID-19 ear is an uncontacted culture that connects without contact. As digital technology is used in various fields and social distancing is implemented, many changes in culture, education, and consumption patterns have also appeared. Also, contemporary society can easily access various cultures around the world with the development of social media. The design trends are recreated by combining originality and tradition and creating a new and colorful culture. Reflecting on this changing trend in the digital culture era, 3D digital makeup works were produced based on the characteristics of the basic patterns of Korean traditional Dancheong. This study reinterpreted the concept, types, and features of Dancheong and the meaning of the basic patterns and features of Dancheong. Besides, this study investigated the concept of 3D digital makeup and the functions and features of 3D face modeling. To express the characteristics of Dancheong, a 3D model using a tablet and a styler pen was used to express the Dancheong style with digital drawing and painting techniques using the Z brush and Adobe Photoshop CC 2020 program. Three 3D digital makeup designs were produced with a Dancheong pattern, peony, and butterfly based on the considerations. Through the above research, makeup artists" creative design presentation can maximize the possibility of expanding the makeup design part. This will be the starting point for creative and individual design production methods and the expansion of design areas.

Introduction: Placenta previa is a condition in which the placenta implants in the poorly vascularized lower uterine segment, which may result in inadequate uteroplacental perfusion, in turn, adversely affect the neonatal outcome. Abnormal placentation may also lead to severe postpartum hemorrhage as placenta separation proceeds. We aimed to evaluate the differences in placental histopathology and perinatal outcomes in pregnancies complicated with placenta previa and controls. Methods: We undertook a retrospective case-control study of 93 pregnancies with placenta previa and 81 controls between 2011 and 2017. Results: Gross findings of the placenta showed that the placentas in placenta previa had significantly higher mean large chorionic plate diameters (18.5 ± 3.2 vs 17.5 ± 2.6 cm, P = .0298), chorionic plate areas (218.4 ± 62.9 cm2 vs 198.7 ± 56.0 cm2, P = .0344), and marginal cord insertion (19.8% vs 8.6%, P = .0411) than control groups. Placental histopathological findings showed that placentas in placenta previa was significantly associated with maternal underperfusion, including villous infarction (50.5% vs 25.9%, P = .0009) and increased intervillous fibrin deposition (38.7% vs 7.4%, P < .0001). Also, women in the placenta previa group had a higher rate of abnormally invasive placenta and severe postpartum hemorrhage. However, placenta previa was not associated with the increased risk of neonatal mortality and morbidity. Conclusion: Abnormal placentation into the poorly vascularized lower uterine segment induces compensatory placental growth and increased surface area in response to reduced placental perfusion, which was consistent with the histopathological findings of coagulative necrosis of chorionic villi and fibrin deposition in the intervillous space. The morphological changes occurring in placenta previa may have important roles in maintaining adequate uteroplacental-fetal perfusion, which may prevent adverse neonatal outcomes.

As Waterpower Generation generates electricity using the difference of altitude of water, also let the turbine revolves through water pipe, at this time the revolving turbine causes exceedingly huge noise. Accordingly, not only those workers in the hydraulic turbine dynamo room are suffering the difficulties in mutual communication, but also those workers in the adjacent office are enduring the obstruction to the business due to the noise. Particularly, since the dynamo room located on the middle between the hydraulic turbine dynamo and the office had been architecturally concluded, not only with all of the reflection materials, but also holds a great volume of 22,800㎥, it functions rather to amplify the Noise that occurs during the operation time of the hydraulic turbine dynamo. Accordingly, after actually measure the architectural acoustic performance on the object of the hydraulic turbine dynamo room, and compare with the forecasted value through a computer simulation, thence this Research has verified the authenticity of the simulation. Based on such authenticity of the forecasting, this Study would intend to propose the architectural acoustic element likely as restraint the amplification of dynamo noise, reduction the noise travelling to the adjacent room, enable to maintain the optimum acoustic condition.

청국장에서 분리한 B. subtilis KC-3(KCCM 42923)균을 이용하여 발효한 두유의 발효정도에 따른 이화학적 특성, 항산화효과 및 AGS 인체위암세포 억제효과 차이를 살펴보았다. 발효진행 된 pH 5.5, pH 5.25, pH 5.0 발효두유의 이화학적 특성을 pH, 균수, 산도, 점도, 아미노태 및 암모니아태 질소를 통해 살펴본 결과, 발효가 진행됨(pH 6.8에서 5.0)에 따라 균수는 8.5×10⁴ cfu/mL에서 7.5×10? cfu/mL까지 증가하고, 산생성과 점도는 높아졌다. 두유는 발효에 의해 단백질이 분해되면서 아미노태 질소 및 암모니아태 질소도 증가하는 경향을 보였다. 발효두유의 항산화 효과를 살펴보기 위해 DPPH, ㆍOH, SOD 유사활성능을 측정해 본 결과, 두유에 비해 발효두유의 항산화 활성이 높아졌고, 발효진행에 따라 그 활성이 더 증가하여 발효두유는 두유에 비해 항산화효과를 가지는 것으로 나타났다. 또한 AGS 인체위암세포에서 성장 억제 효과를 가지는 것으로 나타났다. 발효두유는 두유에 비해 항산화 및 AGS 인체위암세포 성장 억제능을 가지며 이는 발효가 진행됨에 따라(pH 감소) 증가하는 것으로 나타났다. The antioxidative activities and growth inhibitory effects of fermented soymilk (FS) by Bacillus subtilis KC-3 (KCCM 42923) in AGS human gastric adenocarcinoma cells were studied during fermentation at pH 5.5, 5.25 and 5.0. The pH of B. subtilis KC-3 from Cheonggukjang, decreased from 6.8 to 5.0 during the fermentation. The acidity decreased, but amino and ammonia type nitrogen contents increased significantly as pH decreased. FS at pH 5.0 (FS 5.0) exhibited the highest DPPH free radical scavenging activities among other samples. The hydroxy radical scavenging activity of FS 5.0 was found to be approximately 2.5 times higher than that of the non-fermented soymilk (NFS). The SOD-like activity of FS 5.0 was 32.1% at 1.0 ㎎/mL and 50.6% at 2.0 ㎎/mL compared to the NFS of 9.1% and 17.3%, respectively. FS, especially FS 5.0, showed increased anticancer effect in AGS human gastric adenocarcinoma cells. These results suggest that soymilk fermented by B. subtilis KC-3 has increased antioxidative activities and anticancer effects during fermentation (pH 6.0 to pH 5.0).
