Purpose: Many studies have shown that obesity is one of the major causes of lung function decline. However, a longitudinal study of the correlation between changes in obesity degree and lung function is still lacking. This study aimed to analyze alterations in lung function according to changes in body and abdominal fat amount over time in healthy individuals. Methods: A retrospective cohort study of individuals who received annual health screening was performed. Individuals who underwent health screening at least 3 times with follow-up periods more than 5 years were included. Using a linear mixed model, we analyzed associations between the change in total body fat amount/abdominal fat ratio and lung function decline over time by dividing each quartile according to the fat change rate. Results: A total of 15,484 individuals over 40 years old was enrolled prospectively. A longitudinal increase in total body fat amount over time was associated with a predicted value of forced expiratory volume in 1 second (FEV₁p; %) and predicted value of forced vital capacity (FVCp; %) declines, regardless of sex. A similar phenomenon was observed between an increase in abdominal fat ratio and FEV₁p/FVCp decline, which was predominant in males. In addition, the change in abdominal fat ratio showed a significant correlation with differences in the initial values of FEV₁p and FVCp after 40 years old. Conclusion: Increases in total body fat amount and abdominal fat ratio may cause lung function decline over time. (Allergy Asthma Respir Dis 2021;9:171-179)

안경민(Ahn, Kyung Min),강승모(Kang, Seung Mo),안병태(Ahn, Byung Tae) 한국신재생에너지학회 2010 한국신재생에너지학회 학술대회논문집 Vol.2010 No.06

The surface morphology and structural properties of polycrystalline silicon (poly-Si) films made in-situ aluminum induced crystallization at various substrate temperature (300~600) was investigated. Silicon films were deposited by hot-wire chemical vapor deposition (HWCVD), as the catalytic or pyrolytic decomposition of precursor gases SiH4 occurs only on the surface of the heated wire. Aluminum films were deposited by DC magnetron sputtering at room temperature. continuous poly-Si films were achieved at low temperature. from cross-section TEM analyses, It was confirmed that poly-Si above 450?C was successfully grown on and poly-Si films had (111) preferred orientation. As substrate temperature increases, Si(111)/Si(220) ratio was decreased. The electrical properties of poly-Si film were investigated by Hall effect measurement. Poly-Si film was p-type by Al and resistivity and hall effect mobility was affected by substrate temperature.

본 연구는 피부 관리 측면의 노화방지 프로그램을 개발하는 기초자료를 제공할 목적으로 수기 요법과 저출 력 레이저 요법을 이용하여 각각의 요법에 8명씩의 41세에서 58세 사이의 여성들에게 2011년 6월 20일부터 8월 26 일까지 주 2회씩 4주 동안 총 8회에 걸쳐 안면 마사지를 시행하였다. 시행 2, 4, 6, 8회후 눈 밑과 볼의 피부 탄력도 와 눈가와 볼의 멜라닌 양을 측정하여 평균값과 표준편차를 내고 비교 분석한 결과 두 집단 모두에서 탄력도가 유의 적으로 증가하고 멜라닌양은 유의적으로 감소하는 결과가 나타났다. 또한, 탄력도의 증가율과 멜라닌양의 감소율 모 두에서 수기 요법보다 저출력 레이저 요법이 더 효과가 높은 것으로 나타나 저출력 레이저 요법이 안면 피부의 탄력 도와 멜라닌 양에 미치는 효과가 수기 요법보다 높은 것으로 분석되었다. 따라서 저출력 레이저를 이용한 피부 관리 는 안면 피부의 노화방지에 유의하며 새로운 피부 관리의 프로그램으로 활용할 수 있을 것으로 분석되었다. This study aims to provide fundamental data to develop anti-aging programs in the aspect of skin care. To attain the goal, manual therapy and low-power laser therapy were conducted separately to 8 women inthe 40’s and 50’s. They received the facial massage total 8 times twice a week for 4 weeks. According to the result of calculating the average and standard deviation by measuring skin elasticity of the area below their eyes and cheeks and also melanin around eyes and cheeks and conducting comparative analysis, both groups showed significant increase in elasticity and their melanin decreased significantly. The low-power laser therapy showed higher values than the manual therapy both in elasticity increase and melanin reduction; thus, it was analyzed that the low-power laser therapy more highly affects skin elasticity and the amount of melanin in facial skin is greater than that in manual therapy. Therefore, it was analyzed that skin care using low level laser can be significant in anti-aging of facial skin and can be utilized as a program for a new type of skin care.
