목적 농업인을 대상으로 근골격계질환의 예방과 관리를 위한 근력강화운동을 실시하여 심리상태와 신체능력에 미치는 효과를 밝힘으로써 농작업과 관련된 향후 치료프로그램의 기초자료를 제공하고자 하였다 방법 규칙적인 운동프로그램의 참여 경험이 없는 농작업 종사자 28명을 대상으로 8주간 주 3회 근력강화운동을 실시하여 4주 이상 규칙적으로 참여한 대상자의 정신사회적 수준(자아존중감 사회심리적 스트레스) 신체적 수준(장악력 민첩성 동 정적 균형능력 근지구력) 요통 수준의 변화를 측정하였다 결과 근력강화운동에 참여한 대상자들의 자아존중감은 운동전에 비하여 유의하게 향상되었고 사회 심리적 스트레스는 유의하게 감소하였다 장악력 민첩성 동 정적균형능력은 운동 후 모두 유의하게 향상되었으며 요통 수준 또한 유의하게 감소하였다 결론 농업인에게 근력강화운동의 적용은 심리적인 안정을 주고 신체능력을 향상시켜 근골격계질환을 예방하고 관리하는데 적합한 치료프로그램으로 사용될 수 있으며 요통 수준을 감소시키는데 유용한 프로그램이었다. Objectives To evaluate both the psychosocial and physical effects of muscle strengthening exercise on farmers and in so doing evaluate their effect on musculoskeletal disorders in farmers. Methods 28 subjects participated in our muscle strengthening exercise program. Mean age of subjects was 63±13 years. The exercise program was performed 3 times a week during the 8 week studys period Before and after training various measurements were made self esteem scale (SES), psychosocial well being index short form (PWI SF), static and dynamic balance ability grip strength arm curl, time up and go (TUG), functional reach, and oswestry disability index. Results The muscle strengthening exercise program increased the self esteem grip strength and static and dynamic balance of subjects, while psychosocial stress and low back pain levels were decreased significantly (P<0.05) Conclusions The muscle strengthening exercise improved psychosocial and physical status of test subjects. Thus exercise may be an effective strategy for enhancing the psychosocial and physical health of farmers.

In order to develop a confident sampling technique, we designed and constructed a 6-port manifold MFC sampling system for collecting gaseous pollutants in air. Using this instrumentation, we tested the performance criteria of MFC system in terms of: (1) flow rate; (2) MFC-to-MFC variability: (3) tube-to-tube variability: and (4) time. It was interesting to find that the later two factors did not show any significant variations, while the former two show substantially large variations. However, as most of those variabilities are consistent enough to form systematic patterns, we were able to explain the occurrence patterns of all those MFC biases in terms of those tour major variables. The overall results of our experiment suggest that one needs to use correction factor for each MFC unit under a given flow rate to maintain optimal accuracy and precision for sampling of those pollutants.

As demands for new strategies to control methicillin-resistant Staphylococcus aureus (MRSA) increase, studies that gain insight from gut bacteria regarding growth inhibition and anti-virulence strategies have been reported. Although it was reported in several studies that Lactobacillus strains have antibacterial activity against MRSA, the molecular mechanism under these phenomena is unclear. Here, we evaluated the inhibition effect against MRSA Lactobacillus strains isolated from infant stools and performed a multi-omics study. Firstly, we screened the highest growth inhibitory strain and observed that MRSA growth inhibition effect was not correlated with extracellular pH levels, affected by Lactobacillus strains. In the multi-omics study, it was observed that MRSA significantly upregulated arginine deiminase system, proteins related protein folding and synthesis, etc., and downregulated quorum-sensing system, capsular polysaccharide synthesis proteins, etc. by Lactobacillus strain (L. gasseri 20). In this study, the underlying mechanism involved in growth inhibition and anti-virulence of MRSA mediated by lactobacillus strain was discovered.

Nontuberculous mycobacteria (NTM) have been increasingly recognized as an important cause of chronic pulmonary infections. The Mycobacterium avium complex (MAC), which is composed of two species, Mycobacterium avium and Mycobacterium intracelluare, is the most commonly encountered pathogen associated with NTM lung disease. MAC pulmonary infection typically presents in a fibrocavitary form or a nodular bronchiectatic form. However, there have been atypical presentations of MAC pulmonary infections, including solitary pulmonary nodules (SPN). There have been several previous reports of SPN due to MAC infection in the United States, Japan, and Korea. In 2009, Sekine and colleagues reported a case of MAC pulmonary infection presenting with multiple nodules. To date, however, there have been no cases of NTM lung infection with multiple cavitary pulmonary nodules, and neither a fibrotic change nor nodular bronchiectasis. The present case showed a multiple cavitating nodular lung infection due to MAC, which is very rare and different from the typical presentation of MAC pulmonary infections. We also showed that percutaneous transthoracic needle aspiration can be a useful diagnostic tool to evaluate a case of multiple cavitary nodules.
