Abdominal aortic aneurysm (AAA) is a life-threatening disorder worldwide. Fibroblast growth factor 21 (FGF21) was shown to display a high level in the plasma of patients with AAA; however, its detailed functions underlying AAA pathogenesis are unclear. An in vitro AAA model was established in human aortic vascular smooth muscle cells (HASMCs) by angiotensin II (Ang-II) stimulation. Cell counting kit-8, wound healing, and Transwell assays were utilized for measuring cell proliferation and migration. RT-qPCR was used for detecting mRNA expression of FGF21 and activating transcription factor 4 (ATF4). Western blotting was utilized for assessing protein levels of FGF21, ATF4, and markers for the contractile phenotype of HASMCs. ChIP and luciferase reporter assays were implemented for identifying the binding relation between AFT4 and FGF21 promoters. FGF21 and ATF4 were both upregulated in Ang-II-treated HASMCs. Knocking down FGF21 attenuated Ang-II-induced proliferation, migration, and phenotype switch of HASMCs. ATF4 activated FGF21 transcription by binding to its promoter. FGF21 overexpression reversed AFT4 silencing-mediated inhibition of cell proliferation, migration, and phenotype switch. ATF4 transcriptionally upregulates FGF21 to promote the proliferation, migration, and phenotype switch of Ang-II-treated HASMCs.

Purpose: The purpose of the study was to compare community residents' perceptions, participation, satisfaction, and behavioral changes between a health promotion demonstration health center and general health center. Method: The design of the study was ex-post facto that compared community residents in demonstration health centers and general health centers. The sample included 2,261 community residents who were conveniently selected from demonstration (792 participants) and general health centers (1,496 participants). Result: The results of the study were as follows: 1) Perception and participation rates of exercise, nutrition, and hypertension management programs were significantly higher in the participants of demonstration health centers than those of general health centers.; 2) Satisfaction rates of all programs except the smoking cessation program were significantly higher in the participants of demonstration health centers than those of general health centers. However, only the exercise rate among risk behaviors of participants was significantly higher in demonstration health centers than general health centers. Conclusion: Systematic efforts for health promotion were effective not only in improving the community's awareness, participation, and satisfaction of the program, but also in changing health behaviors. This evidence should be used to foster and disseminate health promotion programs toother health centers to improve community residents' health status and quality of life.

The objective of this study is to provide fundamental data for pertinent management of indoor air quality through investigating the size-based characteristics of bioaerosol distributed in the general hospital. Measurement sites are main lobby, ICU, ward and laboratory and total five times were sampled with six-stage cascade impactor. Based on the result of this study, concentrations of airborne bacteria and fungi were the highest in main lobby as followed by an order of ward, ICU and laboratory. Concentrations of airborne bacteria was generally higher than those of airborne fungi and the ratio of indoor and outdoor concentration of both exceeded 1.0 in all the measurement sites of the general hospital. The predominant genera of airborne bacteria identified in the general hospital were Staphylococcus spp.(50%), Micrococcus spp.(15-20%), Corynebacterium spp.(5-20%), and Bacillus spp.(5-15%). On the other hand, the predominant genera of airborne fungi identified in the general hospital were Cladosporium spp.(30%), Penicillium spp.(20-25%), Aspergillus spp.(15-20%), and Alternaria spp.(10-20%). In regard to size distribution of bioaerosol, the detection rate was generally highest on 5 stage($1.1-2.1{\mu}m$) for airborne bacteria and on 1 stage(>$7.0{\mu}m$) for airborne fungi. Cleanliness of facilities in the general hospital and condition of HVAC system should be monitored regularly to prevent indoor air contamination by airborne microorganisms.

화학은 단계별로 개념이 연계 발전되는 학문 체계를 가지므로 고등학교의 화학 I II의 교육 내용은 대학 일반화학과 연계성 측면에서 매우 중요하다. 현재 고등학교 학생들은 심화 선택 최상위 과목인 화학II를 배우지 않고도 이공계 대학에 진학하는 것이 가능하다. 따라서 이러한 학생들이 일반화학을 수강하면서 얼마나 어려움을 겪는지 알아보기 위해 일반화학과 고등학교 화학교재의 내용 연계성 및 학생들의 인식을 조사했다. 연구 결과, 화학I에서는 일반화학 필수 개념의 약 27%밖에 소개하고 있지 않지만, 화학II에서는 약 62%의 내용이 일반화학과 연계되었다. 전남 M대학의 학생들 중 화학II를 배우지 않은 약 70%의 학생들은 일반화학을 배울 때 상대적으로 더 어려워했고, 학업성취도도 상대적으로 낮았을 뿐 아니라, 화학에 대해 흥미도도 낮게 조사되었다.

Purpose: This study was aimed to examine changes of hospital nurse staffing by hospital characteristics during 2008-2010. Methods: The study sample included 44 tertiary hospitals, 226 general hospitals, and 532 non-general hospitals that were operating during 2008-2010. Grade of nursing management fee was categorized from Grade 1(highest) to 6 (lowest) in tertiary hospitals, l or Grade 7 in general hospitals and non-general hospitals based on the nurse-to-bed ratio. For data analysis, ${\chi}^2$ and GEE were conducted. Results: For three years, the number of tertiary hospitals below Grade 2 were increased from 8 to 12, the number of those above Grade 4 were decreased from 15 to 6. The number of general hospitals above Grade 6 decreased from 123 to 86. Tertiary hospitals and general hospitals had more possibilities to improve nurse staffing grade than general hospital (OR 79.69, 95% CI 50.77~125.09, OR 11.25, 95% CI 8.15~15.53, respectively). Greater likelihood of improvement in grade of nursing management fee was found in university hospital or hospitals with 300 or more beds than other types of hospitals. Conclusion: Differentiating nurse staffing system by hospital type and increasing financial incentives according to the grades are needed to improve hospital nurse staffing.

Purpose: The purpose of this study was to identify the effects of the heated-humidified breathing circuit applied on the body temperature, shivering, and thermal comfort of general anesthesia patients. Methods: The participants were patients who received general anesthesia at University Hospital K located in City B, with 25 patients in the experimental group and 25 patients in the control group. The period of this study was from Mar 19 to Apr 26, 2019. The experimental equipment included a heated-humidified breathing circuit, which connects the intubation tube with the anesthesia machine for mechanical ventilation after airway intubation in general anesthesia patients. Results: The body temperature, shivering, and thermal comfort after surgery were significantly different between the two groups (p<.001). However, the body temperature during surgery was slightly different between the experimental group and the control group. Conclusion: A heated-humidified breathing circuit may be actively used in a warming method to prevent the hypothermia of general anesthesia patients.

In this paper, diversity-multiplexing tradeoff (DMT) of three-user wireless multiple-antenna cooperative systems is investigated in general fading channels when half-duplex and decode-and-forward relay is employed. Three protocols, i.e., adaptive protocol, receive diversity protocol, and dual-hop relaying protocol, are considered. The general fading channels may include transmit and/or receive correlation and nonzero channel means, and are extensions of independent and identically distributed Rayleigh or Rician fading channels. Firstly, simple DMT expressions are derived for general fading channels with zero channel means and no correlation when users employ arbitrary number of antennas. Explicit DMT expressions are also obtained when all users employ the same number of antennas and the channels between any two users are of the same fading statistics. Finally, the impact of nonzero channel means and/or correlation on DMT is evaluated. It is revealed theoretically that the DMTs depend on the number of antennas at each user, channel means (except for Rayleigh and Rician fading statistics), transmit and/or receive correlation, and the polynomial behavior near zero of the channel gain probability density function. Examples are also provided to illustrate the analysis and results.

Objectives: General livestock farmers are known as a high riskgroup for zoonoses, but studies of general livestock farmers in regard tozoonoses have been rare in Korea. We surveyed awareness of zoonoses amonggeneral livestock farmers to suggest directions for education. Methods: A questionnaire was developed examining the workbehaviors and risk factors of general livestock farmers. We conducted a questionnairesurvey on awareness on zoonoses among 265 general livestock farmers. Results: The awareness rates for zoonosis itself,brucellosis, and q-fever were 13.0%, 65.0%, and 2.3%, respectively. The awarenessrate of zoonoses and brucellosis tended to increase with sex. Conclusions: Livestock is the principal reservoir ofzoonoses. Therefore, effective working guidelines for preventing zoonoses amonggeneral livestock farmers must be developed and an educational program onzoonoses is needed for general livestock farmers. Furthermore, publicityactivities on the prevention of zoonoses are needed for high-risk groups.
