This study is a descriptive study to analyze the hand washing practice of nurses working in clinic applying health belief model. This research involved 162 clinical nurse at G city. The data were collected from Sep 1, 2017 to Oct 31, 2017. The collected data were analyzed using an independent t-test, 1-way ANOVA, pearson's correlation coefficient and multiple regression analysis, where p-values of <0.05 were considered statistically significant by using SPSS 20.0. The overall practice of hand washing by general subjects were high 3.1 in all subjects, but there was no statistically significant difference. Health beliefs about hand washing practice according to general characteristics showed significant difference in perceived benefits (p<0.05), and there was a significant difference in perceived benefits and perceived barriers in age(p<0.05). In regard to the correlation among the subfactor of health beliefs, benefits had a statistically significant negative correlation to barriers and, positively correlated to cues to action. The results of this study suggest that continuing education of infection management in hospitals considering health beliefs about proper hand washing training will enhance hand washing practice.

Seven seed samples of corn obtained from Kangweon Provincial Office of Rural Development, Kerea were tested for seed-borne fungi, and found that all the samples tested were infected with Fusarium moniliforme to an extent of $6.0{\sim}79.5%$. Severely infected seed samples showed poor germination on blotter. Seed component plating showed that the fungus present not only in tip caps, pericarps and endosperms, but also in embryos. Heavy infection of the fungus caused severe seed rot and seedling blight in soil, but the damage was not severe and many plants grew without any symptoms when the seeds with light infection were sown in soil. However the fungus was frequently detected from inside of the stems of healthy looking seedlings. The results indicate that the fungus transmit from seed to plant systemically. In inoculation experiments, the fungus produced stem rots on corn plants of 110 days old. The cultivar of Hwangok 3 was revealed more susceptible to the fungus than that of Suweon 19.

Background : Primary multidrug-resistant tuberculosis is defined as Mycobacterium tuberculosis isolates that are resistant to at least isoniazid and rifampin in never-been-treated tuberculosis patients, and this malady is caused by the transmission of a resistant strain from one patient, who is infected with a resistant Mycobacterium tuberculosis strain, to another patient. The prevalence of primary multidrug-resistant tuberculosis could be a good indicator of the performance of tuberculosis control programs in recent years. We conducted a case-control study to identify the risk factors for primary multidrug-resistant tuberculosis. Methods : From January 1, 2001 to, June 30, 2003, by conducting prospective laboratory-based surveillance, we identified 29 hospitalized patients with P-MDRTB and these patients constituted a case group in this study. The controls were represented by all the patients with culture-confirmed drug susceptible tuberculosis who were admitted to National Masan Hospital during the same study period. The odds ratios for the patients with primary multidrug-resistant tuberculosis, as compared with those of the patients with drug susceptible tuberculosis, were calculated for each categorical variable with 95% confidence intervals. Results : Multivariate logistic regression showed that the presence of diabetes mellitus (odds ratio 2.68; 95% confidence interval, 1.05-6.86) was independently associated with having primary multidrug-resistant tuberculosis. Conclusion : This study has shown that diabetes mellitus might be one of the risk factors for primary multidrug-resistant tuberculosis.

선진 전력시장의 경우, 전력산업의 환경변화에 따라 소비자의 역할이 증대되고 있으며 이와 더불어 IT 기반의 다양한 소비자 중심의 전력부가서비스의 개발이 시도되고 있거나 일부 제공되고 있다. 이러한 서비스의 발전은 시간이 흐르면서 단방향이 아닌 양방향 통신 기반의 소비자 중심 서비스에 대한 연구로 확대되고 있다. 특히, 미국 EPRI의 IntelliGrid 컨소시엄에서 제시한 수용가 포탈 시스템은 소비자 영역내의 장비와 에너지 서비스 기관 간의 양방향 통신을 전제함으로써 이루어지는 통합적인 개념의 서비스 기반으로써, 공급자를 포함한 ESP(Energy Service Provider)와 소비자는 수용가 포탈을 기반으로 원활한 커뮤니케이션을 수행하고 그 결과를 이용한 부가적 이익을 누릴 수 있게 된다. 이에 비해 국내의 전력부가서비스 제공 수준은 이제 겨우 시작 단계에 불과하지만, 서비스에 대한 인식 정도와 IT기술의 발전 속도를 생각해 본다면 머지않아 국내 전력산업에서도 현재의 서비스 제공 수준을 한 단계 넘어선 양방향 통신 기반의 수준 높은 전력부가서비스를 요구하게 될 것이다. 따라서, 국내 환경에 적합한 수용가 포탈 시스템 기반의 전력부가서비스 창출은 수용가에게는 비용 절감이 가능한 합리적인 소비를 제시하고, ESP(Energy Service Provider)에게는 부하·수요관리 및 투자비를 절감할 수 있는 기회를 제공해야 할 것이다. 본 논문에서는 새로운 전력부가서비스 기반인 수용가 포탈시스템을 분석하고, 현행 전력부가서비스의 현황과 동향 분석, 적용가능 기술 분석, 타 산업 벤치마킹을 통해 국내환경에 적합한 수용가 포탈 시스템 기반의 전력부가서비스 선정 및 구축 방안을 제시하고자 한다.원 사용이 가능하도록 설계하였다.서버로 분산처리하게 함으로써 성능에 대한 신뢰성을 향상 시킬 수 있는 Load Balancing System을 제안한다.할 때 가장 효과적인 라우팅 프로토콜이라고 할 수 있다.iRNA 상의 의존관계를 분석할 수 있었다.수안보 등 지역에서 나타난다 이러한 이상대 주변에는 대개 온천이 발달되어 있었거나 새로 개발되어 있는 곳이다. 온천에 이용하고 있는 시추공의 자료는 배제하였으나 온천이응으로 직접적으로 영향을 받지 않은 시추공의 자료는 사용하였다 이러한 온천 주변 지역이라 하더라도 실제는 온천의 pumping 으로 인한 대류현상으로 주변 일대의 온도를 올려놓았기 때문에 비교적 높은 지열류량 값을 보인다. 한편 한반도 남동부 일대는 이번 추가된 자료에 의해 새로운 지열류량 분포 변화가 나타났다 강원 북부 오색온천지역 부근에서 높은 지열류량 분포를 보이며 또한 우리나라 대단층 중의 하나인 양산단층과 같은 방향으로 발달한 밀양단층, 모량단층, 동래단층 등 주변부로 NNE-SSW 방향의 지열류량 이상대가 발달한다. 이것으로 볼 때 지열류량은 지질구조와 무관하지 않음을 파악할 수 있다. 특히 이러한 단층대 주변은 지열수의 순환이 깊은 심도까지 가능하므로 이러한 대류현상으로 지표부근까지 높은 지온 전달이 되어 나타나는 것으로 판단된다.의 안정된 방사성표지효율을 보였다. $^{99m}Tc$-transferrin을 이용한 감염영상을 성공적으로 얻을 수 있었으며, $^{67}Ga$-citrate 영상과 비교하여 더 빠른 시간 안에 우수한 영상을 얻을 수 있었다. 그러므로 $^{99m}Tc$-transierrin이 감염 병소의 영상진단

In order to protect Rescue 119 workers exposed on the spot from potential infection, this study identified their awareness and practices of infection control so that it could help preventing them from infection and also provide basic materials necessary for pre-hospital infection control. This study applied questionnaire survey to total 215 Rescue 119 workers at fire stations in Jeonbuk province, Jeonnam province and Gwangju city from July 14 to Sept. 14, 2006 for the benefit of data collection. The questionnaire about possible associations between awareness and practices of infection control consisted of total 46 times across 6 categories such as washing hands during emergency activities ; fluid therapy and injection ; respirator maintenance; individual hygienics ; disinfectant supplies and equipments maintenance ; and control of infectious wastes. And collected data were processed using SPSS statistic program to analyze frequency and percentage, mean and standard deviation, Pearson's correlation coefficient, t-test and one-way ANOVA. As a result, this study came to the following conclusions : In terms of awareness about infection control, our respondents showed highest awareness about infectious waste control, and also showed highest level of practices in washing hands during emergency activities. Throughout all domains, awareness means were higher than practice means. In particular, infectious waste control was the domain of significant differences between awareness and practices. In terms of associations between awareness and individual characteristics, it was found that female rescue worker group and hospital/general hospital career group (before joining the Rescue 119) showed significantly higher awareness on statistic level. In regard to associations between individual characteristics and practices, it was found that female rescue worker group showed higher level of practices than male group on statistic level. This study also analyzed correlations between rescue workers' awareness and practice of infection control. As a result, it was found that the higher awareness was in correlations with the higher practices across all 6 domains including washing hands. In addition, the higher awareness of a questionnaire item was in significantly positive correlations with the higher practice of other items. However, our respondents showed high awareness about anti-infection, but low practices in reality. This indicates necessity of devising possible solutions to improve the practices as much as awareness. Especially, it was noted that major reasons for insufficient practices of infection control guideline come from unhabituated practices and lack of supports for infection-preventing supplies and protective device (mask, etc). Hence, it is necessary to provide more infection-preventing supplies for local rescue workers sufficiently, in parallel with steady habituation of infection control. Furthermore, it is required to manage and study infection control policies even at pre-hospital step in efforts for effective infection control, education and activities.

Purpose : This study was designed to identify the perception and practice level of infection control among korean medical doctors and to identify factors that may influence the performance and practice level. Methods : Data were collected using the on­line survey method. Seven hundred and eighty four Korean medical doctors(KMD) participated the survey. The study was conducted from December 2018 to January 2019. Results : The results of this study are as follows. 1. Participants who experienced infection risk by needles or sharp instruments were 596(76%). and participants who had experienced blood or body fluid contact with the mucous membrane or skin of the patient during treatment were 226(28.8%) of them. 2. The degree of perception and practice of the infectious guideline was higher in the group over 50 years, in the doctor group, in the group with more than 6 years experience in clinic and in the group who work in the hospital. (p < 0.05) 3. In the performance of the infection control management related to the Korean medical treatment, the practice level of the article 'Discard the remaining needle that used for one patient' was the lowest at 4.02, 'Identify the patient and check the validity period of sterilization of medicines or instruments' was the second lowest in 4.16. 4. Among the contents of "Prevention of Nosocomial infection and Sanitary Safety Guidelines" issued by the Korean Medical Association in 2008, the guideline "Prevention of infection by pathogens such as HIV, MRSA, SARS" were lowest article in the perception and practice level of participants. 5. Regression analysis was performed to find out the factors affecting perception and performance of the participants. The regression model showed significant difference in the regression model of the working years. (p < 0.05) 6. In order to examine the effect of the variables on the perception and practice of the infectious guideline, the mediated effect of the knowledge and education level according to the years of working, age, education degree was found to be significant only in the education degree variable. (p < 0.05) In conclusion : in order to improve the perception and practice of infectious control of Korean medicine doctors, it is necessary to include the contents of infection management as essential education during the continuing education of Korean medicine association.

In this study, we developed a module that can perform two functions at the same time through interworking between a personal recognition module and a heat detection module in the era of COVID-19. This can simultaneously solve the problem of compatibility of the personal recognition module that occurs in the existing system and the problem of secondary infection that can occur during congestion due to the separate implementation of heat detection. Therefore, in this study, NFC and Bluetooth motherboards were developed, and an array-type non-contact temperature sensor was applied to detect heat. The developed system is expected to be able to realize both access control of floating population and effective quarantine at the same time in public institutions or private companies that require AI automated access control. In addition, it is judged that it is possible to link the embedded programming and web programming implementation method using the module of the development system to the educational program.

The purpose of this study was to investigate the current status of postpartum depression intervention program performed in Korea and to evaluate its effectiveness. Of the Korean academic journals reported until November 2018, 13 experimental studies were selected and used for final analysis. The average age of the subjects was 26.9 to 34.4 years, and subjects were puerperal women or couples. The sample size was 6~39 (mean: 20.4) in the experimental group, 5~40 in the control group (mean: 20.0), and the intervention program consisted of 0.5~12 weeks/2~14 sessions/10~120 minutes per session. The design of all the studies was a non-equivalent control group pre-post test design. The main dependent variables, postpartum depression, fatigue, and maternal role self-confidence, were all found to have a statistically significant median level of effect size in the meta-analysis. This study confirms the composition and effects of various experimental studies used to mediate postpartum depression in Korea. This could be used as specific evidence-based data to form an optimal postpartum intervention program.

Ascites is a condition in which body fluids are abnormally accumulated in the fish's abdominal cavity, and is an important indicator of the health of flounder. Ascites can occur in the process of infection with bacteria, viruses, parasites, etc., which causes abdominal distension, sluggish growth, and weight loss. In this paper, we tried to find the correlation with other symptoms or diseases that affect ascites symptoms in flounder. As experimental data, ascites symptoms were divided into three states: no ascites, ascites transparent, and ascites opaque, and disease diagnosis data of cultured flounder collected for 7 years were used. After performing an appropriate preprocessing process for the random forest machine learning method, other symptoms and disease factors related to ascites were extracted, and it was confirmed that the proposed model could present the main factors related to ascites.
