본 연구의 목적은 일상생활 속에서도 누구나 쉽고 편하게 따라 할 수 있는 노인의 신체기능 저하예방 및 개선에 적합한 표준운동프로그램을 개발한 후, 그 효과를 검증하는 것이다. 연구대상은 서울시 마포구 화신경로당에 등록되어 있고, 본 프로그램에 참여한 총 36명(남성노인 10명, 여성노인 26명)의 노인으로 선정하였으며, 평균연령은 77세이다. 프로그램은 2011년 8월 19일부터 10월 18일까지 총 3개월 동안 주 2회씩 12주간, 총 18회를 실시하였으며, 안무가 1명과 보조연구원 1명이 프로그램을 진행하였다. 조사도구는 설문지로 SFT(Senior Fitness Test)를 사용하였으며, 노인 체력 테스트로 본 프로그램의 효과분석을 실시하였고 세부적으로는 상·하체 유연성, 상·하체 근력, 평형성, 민첩성 에 관한 테스트를 실시하였다. 사후검사는 프로그램 18회를 모두 진행하고 10월 18일 프로그램이 종료된 후, 사전검사와 동일한 방법으로 실시하였다. 자료처리는 SPSS Windows 15.0 version 을 이용하여 빈도분석, 대응표본 t-test를 실시하였으며, 그 결과는 다음과 같다. 첫째, 참여노인의 체력 요인에 대한 차이분석 결과, 평형성을 제외한 하체유연성, 상체유연성, 하체근력, 상체근력, 평형성, 민첩성 모든 요인에서 통계적으로 유의하게 증가하였다. 둘째, 참여노인의 신체구성비에 대한 차이 분석 결과, 체지방율과 BMI는 통계적으로 유의하게 감소하였고, 기초대사량과 근육량은 유의하게 증가하였다. 또한 체지방량은 감소하여 프로그램에 따른 긍정적인 효과가 검증되었다. The purpose of this study was to verify the effect of poor physical function of the elderly in everyday life that anyone can easily and comfortably suitable for the prevention and improvement to develop a standard exercise program after. Distribution of Hwa-Sin-dong, Mapo-gu, Seoul incarnation is registered in the senior center, was selected and a total of 36 patients (10 patients, elderly men and elderly women, n = 26) participated in this program for the elderly, the age range from 61 years to 91-year-old and the average age 77-year-old. Program for three months from August 19, 2011 10 18 in 12 weeks, a total of 18 times, twice a week was conducted by research assistant choreographer with 1 program. Research tool, a detailed questionnaire to the elderly as a fitness test this program was carried out to analyze the effects of SFT (Senior Fitness Test), the upper and lower body flexibility (right, left), upper and lower body strength, balance (right, left), agility test was conducted. Post-inspection program 18 times in the same way as the pre-test and after the program ends Oct. 18, and all proceeds were conducted. Data processing were analyzed using SPSS Windows 15.0 version to the corresponding sample t-test was conducted, and the results are as follows. First, the analysis for differences in participation in physical factors of the elderly, lower body flexibility, balance, except for lower body strength, upper body flexibility, upper body strength, balance, and agility in all factors statistically significantly increased. Second, the difference analysis results for the participation of the elderly in the Composition of the body, was a statistically significant reduction in the percentage of body fat and BMI, basal metabolic rate, muscle mass increased significantly increased. Also reduced body fat, according to the program has a positive effect was verified.

This study was conducted to identify requirements and improvements for policies related to energy welfare by investigating and analyzing household characteristics, residential building information, elements of energy use, and energy welfare status among the energy poverty. In this study, the energy consumption of the energy poverty and support policies are investigated, and characteristics of each are analyzed. The average number of household members in the energy poverty group was 2.3, and the average monthly household income of the households was 93.3 million won. The average expenditure on energy use per year was 947,957 won, which was the highest in January, February, and December. The most desirable energy welfare policy was the reduction or reduction of electricity cost.
Hydrogen Peroxide- and Nitric Oxide-mediated Disease Control of Bacterial Wilt in Tomato Plants
Hong, Jeum Kyu,Kang, Su Ran,Kim, Yeon Hwa,Yoon, Dong June,Kim, Do Hoon,Kim, Hyeon Ji,Sung, Chang Hyun,Kang, Han Sol,Choi, Chang Won,Kim, Seong Hwan,Kim, Young Shik The Korean Society of Plant Pathology 2013 Plant Pathology Journal Vol.29 No.4
Reactive oxygen species (ROS) generation in tomato plants by Ralstonia solanacearum infection and the role of hydrogen peroxide ($H_2O_2$) and nitric oxide in tomato bacterial wilt control were demonstrated. During disease development of tomato bacterial wilt, accumulation of superoxide anion ($O_2{^-}$) and $H_2O_2$ was observed and lipid peroxidation also occurred in the tomato leaf tissues. High doses of $H_2O_2$ and sodium nitroprusside (SNP) nitric oxide donor showed phytotoxicity to detached tomato leaves 1 day after petiole feeding showing reduced fresh weight. Both $H_2O_2$ and SNP have in vitro antibacterial activities against R. solanacearum in a dose-dependent manner, as well as plant protection in detached tomato leaves against bacterial wilt by $10^6$ and $10^7$ cfu/ml of R. solanacearum. $H_2O_2$- and SNP-mediated protection was also evaluated in pots using soil-drench treatment with the bacterial inoculation, and relative 'area under the disease progressive curve (AUDPC)' was calculated to compare disease protection by $H_2O_2$ and/or SNP with untreated control. Neither $H_2O_2$ nor SNP protect the tomato seedlings from the bacterial wilt, but $H_2O_2$ + SNP mixture significantly decreased disease severity with reduced relative AUDPC. These results suggest that $H_2O_2$ and SNP could be used together to control bacterial wilt in tomato plants as bactericidal agents.

Purpose: A tracheostomy is often used to wean patients off the ventilator, as it helps maintain extracorporeal membrane oxygenation (ECMO) without sedation. A percutaneous dilatational tracheostomy (PDT) performed in critically ill patients is widely accepted, however, its feasibility and safety in ECMO is unclear.Methods: This retrospective observational study included 78 patients who underwent a PDT and ECMO at the surgical intensive care unit (SICU) in a tertiary hospital between January 1, 2016 and December 31, 2019. We analyzed their medical records, including PDT-related complications and clinical variables.Results: The median values of hemoglobin, platelet count, international normalized ratio, partial thromboplastin time, and activated partial thromboplastin time before the tracheostomy were 9.2 (8.5-10.2) g/dL, 81 (56-103) × 103/dL, 1.22 (1.13-1.30), 15.2 (14.3-16.1) seconds, and 55.1 (47.4-61.1) seconds, respectively. No clotting was observed within the extracorporeal circuit, however, minimal bleeding was observed at the tracheostomy site in 10 (12.8%) patients. Of 4 patients with major bleeding, local hemorrhage was controlled in 3 patients, and intratracheal bleeding continued in 1 patient. The mortality rate was 60.9% and 57.1% in the complication and no-complication group, respectively. The durations of SICU stay, hospital stay, and mechanical ventilation were not statistically different between the groups.Conclusion: A PDT performed in critically ill patients was associated with a low rate of bleeding. Complications did not appear to significantly affect the patient outcome. PDT can be performed in patients who usually require a tracheostomy to maintain ECMO.
