Performance of Preventive Actions to be Exposed to Infection in Emergency Nurses and its Influencing Factors

Abstract: Purpose: The purpose of this study was to identify factors influencing on performance of preventive actions to be exposed to infection in emergency nurses. Methods: Participants were 200 emergency nurses working in a regional emergency medi- cal center, 4 local emergency medical centers, and 5 local emergency medical facilities in B city. The data were analyzed with descriptive statistics, independent t-test, ANOVA, Scheffes test, Pearson's correlation coefficients, and stepwise multi- ple regression analysis using SPSS/WIN 21.0 programs. Results: There was no difference in performance of preventive actions to be exposed to infection by socio-demographic and job-related characteristics. The results of stepwise multiple regression analysis showed that levels of perception of preventive actions to be exposed to infection (β=.40, p<.001) and protective environment on exposure to infection (β=.22, p<.001) were significantly associated with performance of pre- ventive actions, explaining 26.3% of the variance. Conclusion: In conclusion, improving performance of preventive actions to be exposed to infection is important to protect emergency nurses from exposure to infection. Thus, efforts to enhance protective environment on exposure to infection and to improve perceptions of preventive actions to be exposed to infection are necessary to improve the performance of preventive actions in emergency nurses.

가상현실재활시스템 적용에 따른 뇌졸중 환자의 일상생활활동, 인지기능, 자아존중감의 개선효과

Abstract: 본 연구의 목적은 산학연 공동기술개발사업으로 개발한 가상현실재활시스템이 뇌졸중 환자에게 긍정적인 영향을 주는지 임상 실험으로 알아보고 이를 통해 개발제품의 임상적 사용 가능성을 검증하기 위함이다. 임상실험을 통해 검증하고자 가상현실재활시스템을 재활병원에 입원하고 있는 뇌졸중 24명(뇌출혈 13명, 뇌경색 11명)에게 제공하였다. 실험군(13명)에는 가상현실재활시스템 위주의 훈련을 실시하였고, 대조군(11명)에는 재활치료의 유형인 보편적 기능훈련으로 일상생활활동 훈련, 지필물과 테이블 탑 위주의 인지재활 훈련, 운동조절 훈련을 실시하였다. 실험군과 대조군 모두 주 3회 하루 2회씩 총 8주간 실시하였다. 두 집단 모두 사전사후 기능적 독립 측정(Functional Independent Measure; FIM), 한국형 간이정신상태검사(Mini-Mental State Examination for Korean; MMSE-K), 자아존중감척도 평가를 실시하였다. 실험결과 가상현실재활시스템을 제공한 집단과 보편적 재활치료를 받은 집단이 일상생활활동, 기초인지, 자아존중감척도에서 유사한 결과를 보였다.중재 전후를 비교해 본 결과 가상현실재활시스템을 제공한 집단이 중재 전보다 중재 후에 일상생활활동, 기초인지, 자아존중감에서 모두 의미 있는 향상이 있었다(P<.05). 산학공동으로 개발한 가상현실재활시스템이 뇌졸중 환자의 일상생활 기능과 기초 인지능력을 회복시키고, 삶의 만족과 인간행동의 원인이 되는 자아존중감에 긍정적인 영향을 보여 주었기 때문에 가상현실재활시스템의 임상 적용 가능성을 긍정적으로 확인하였다. 추후 연구에서는 가상현실재활시스템을 뇌손상 환자와 치매 환자의 다양한 기능 회복에 대한 임상적 유용성을 검증할 필요가 있다.

Detecting response patterns of zooplankton to environmental parameters in shallow freshwater wetlands: discovery of the role of macrophytes as microhabitat for epiphytic zooplankton

Abstract: Freshwater macrophytes improve the structural heterogeneity of microhabitats in water, often providing an important habitat for zooplankton. Some studies have focused on the overall influence of macrophytes on zooplankton, but the ef-fects of macrophyte in relation to different habitat characteristics of zooplankton (e.g., epiphytic and pelagic) have not been intensively studied. We hypothesized that different habitat structures (i.e., macrophyte habitat) would strongly af-fect zooplankton distribution. We investigated zooplankton density and diversity, macrophyte characteristics (dry weight and species number), and environmental parameters in 40 shallow wetlands in South Korea. Patterns in the data were analyzed using a self-organizing map (SOM), which extracts information through competitive and adaptive properties. A total of 20 variables (11 environmental parameters and 9 zooplankton groups) were patterned onto the SOM. Based on a U-matrix, 3 clusters were identified from the model. Zooplankton assemblages were positively related to macrophyte characteristics (i.e., dry weight and species number). In particular, epiphytic species (i.e., epiphytic rotifers and cladocer -ans) exhibited a clear relationship with macrophyte characteristics, while large biomass and greater numbers of macro-phyte species supported high zooplankton assemblages. Consequently, habitat heterogeneity in the macrophyte bed was recognized as an important factor to determine zooplankton distribution, particularly in epiphytic species. The results indicate that macrophytes are critical for heterogeneity in lentic freshwater ecosystems, and the inclusion of diverse plant species in wetland construction or restoration schemes is expected to generate ecologically healthy food webs.

Method for providing font service on service page and system for executing the method

Abstract: Provided is a method of providing font services by using an item server and a service server, including: the item server maintaining font providing information including font information and area information associated with the font information, for each user in a user database; the service server maintaining service page database including text associated with each area of the service page associated with the user; the service server receiving the font providing information associated with the user from the item server; generating the service page in which a text image, corresponding to the text associated with a certain area of the service page and generated according to the font information associated with the certain area, is displayed in the certain area, based on the received font providing information; and providing the generated service page by transmitting to a user terminal.

Automotive Diagnostic Gateway using Diagnostic over Internet Protocol

Abstract: Recently, Ethernet-based Diagnostic Over Internet Protocol (DoIP) was applied to automotive systems, and in-vehicle gateways have been introduced to integrate Ethernet with traditional in-vehicle networks, such as the local interconnect network (LIN), controller area network (CAN) and FlexRay. The introduction of in-vehicle gateways and of Ethernet based diagnostic protocols not only decreases the complexity of the networks, but also reduces the update time for ECU software reprogramming while enabling the use of a range of services, including remote diagnostics. In this paper, a diagnostic gateway was implement for an automotive system, and the performance measurements are presented. In addition, a range of applications provided by the diagnostic gateway are proposed.
