Purpose:The infection and isolation program used at a university hospital in A city was assessed and improved to provide medical staff with easy-to-understand information on isolation precautions and infectious diseases. Methods: Based on the results of the root cause analysis, the infection and isolation alarm computer program was improved. Subsequently, a survey was conducted with infection control leaders and unit managers (n=98) within the department to evaluate the degree of improvement. Results: The isolation registration and release procedures were simplified and unified to prevent confusion among the relevant departments. Additionally, the screen composition was improved so that various information related to infection can be easily accessed. After improvement in the program, the rate of isolation registration (53.0% to 100.0%, p<.001) and user satisfaction (67.6% to 92.2%) improved. Conclusion: This study will help improve the program so that other medical institutions can comply with the isolation precautions in accordance with the type of infections.

초음파 검사 후 완전히 제거되지 않고 남아있는 Gel은 미생물이 증식하기에 좋은 조건을 가지고 있다. 따라서 본 연구자들은 초음파 탐촉자의 위생관리 실태와 위생과 감염에 대한 인식의 정도를 알아보기 위해서 2003년 12월부터 서울지역에 있는 42개의 병원을 대상으로 전화설문을 시행하였다. 또한 세 대의 초음파 장치 탐촉자에서 시료를 채취하여 미생물을 배양 증식한 후 탐촉자의 오염된 정도를 알아보았다. 21개 병원만이 탐촉자의 위생관리를 실시하였고, 소독 방법은 주로 알콜솜을 많이 이용하였다. 위생관리 주기는 14개 병원만이 매일 하는 것으로 조사되었다. 탐촉자에 묻은 Gel제거 방법은 면수건을 많이 이용하였다. 감염의 위험에 노출되어 있는 환자의 초음파 검사 시 감염예방관리를 하고 있는 병원은 32개였고 환자 검사 시 탐촉자를 비닐커버나 외과용 장갑, 알콜 소독 후 사용하고 있는 것으로 조사되었다. 감염 인식도 조사에서 초음파 탐촉자 사용법이 비위생적이라는 생각이 78.6%(33개)였고, 탐촉자를 통한 세균이 감염여부에 대해 54.8%(23개)가 감염될 수 있을 것으로 생각하고 있었다. 탐촉자에서 채취한 시료를 배양한 결과 세균과 진균이 셀 수 없이 너무 많이 오염되어 있었고 대장균은 검출되지 않았다. 결론적으로 초음파 검사 후에는 탐촉자에 묻어있는 Gel에서 세균이 증식하여 감염이 될 수 있으므로 완전히 제거하여 환자간 교차 감염의 위험요인을 줄이는 것과 감염관리에 대한 의식전환이 필요하다고 생각된다.

Purpose: This study aimed to develop and assess the impact of an integrated infection control education program on the awareness, attitudes, and performance of infection control among caregivers in long-term care facilities. Methods: Participants were recruited from two long-term care facilities with 25 caregivers in both the experimental group and the control group. This study used non-equivalent control group quasi-experimental pre-post design. The effectiveness of a developed Integrated Infection Control Education Program was evaluated based on infection control awareness, attitudes, and performance. Data were analyzed using SPSS/WIN 28.0 through descriptive statistics, chi-square tests, Fisher's exact tests, and independent t-tests. Results: There was a statistically significant difference in the degree of awareness (t=-5.00, p<.001), attitude (t=-4.91, p<.001), and performance (t=-6.66, p<.001) of infection control between the two groups. Conclusion: Given these results, the integrated infection control education program significantly improved infection control awareness, attitudes, and performance among caregivers in long-term care facilities. This study is noteworthy because it provided comprehensive education on infection control practices to caregivers in environments that are particularly susceptible to infections, especially following COVID-19. This educational program is actively utilized and validated in practice, it would enhance the infection control performance of caregivers, thereby reducing infection rates within facilities, shortening the length of stay for elderly residents in long term care facilities, and contributing to the reduction of healthcare costs.

Effect of root-knot nematode (Meloidigyne sp.) 1 infection on the growth and quantity of the inorganic substances in 6 year-old ginseng (Panax ginseng C.A. Meyer) was investigated. Naturally infected 6 year-old ginseng roots were grouped into 3 such as healthy, moderate, and heavy according to the degree of the nematode infection. The roots were sampled in the middle of October, 1980 for chemical analysis. Growth of roots in terms of fresh weight, dry weight, length and diameter was greatly reduced by the nematode infection. The content of inorganic substances was different among the various parts of ginseng roots and according to gall index. Phosphorous and nitrogen contents of the healthy ginseng roots were tend to higher than those of the infected ones, whereas calcium was high in infected roots in the order of heavy, moderate, and healthy. Content of the other inorganic substances was highest in the moderately infected roots, and lowest in the heavy one.

Amputation of diabetic foot ulcer and infection is a critical modality for saving a patient's life from life threatening infections or ischemic limbs. However, it can cause serious handicaps or complications, such as lifetime shortening and re-amputation of the other limb. The minimal amputation is the main goal of amputation in diabetic patients. However, insufficient amputation can have a harmful effect on patients. The decision of amputation is very difficult and should be made using multidisciplinary approaches. All aspects of the patient's situation, including vascular status, degree of infection, and medical conditions should be considered. The foot surgeon should keep in mind the notion that proper amputation can lead to a new life for diabetic foot patients.

This study investigated the relationship between knowledge of COVID-19, the risk of exposure to subjective infectious diseases, and the degree of infection control practices for dental personnel. For dental personnel currently working in dentistry, a survey consisting of 10 questions about COVID-19 knowledge and 63 questions about infection control practices was conducted. This study analyzed 126 survey data collected by distributing questionnaires form May 30 to June 20, 2020. Data was analyzed using t-test, ANOVA, and Pearson correlation. The average level of knowledge of COVID-19 was 5.44 out of 10, the average risk of exposure to infectious diseases was 3.86 out of 5, and the average level of infection control practices was 4.05 out of 5. The risk of exposure to infectious diseases was positively correlated with dental waste (r=.184). It was found that there was a significant positive correlation between infection control practices and sub-factors of infection control practices (p<0.001). To prevent the spread of COVID-19 and infectious diseases and to reduce the risk of exposure to infectious diseases for dental personnel, the practice of infection control should be improved. It is necessary to cultivate infection control experts and have mandatory infection control education and social regulations.

Purpose: This study was conducted to identify influencing factors on the performance of healthcare-associated infection control and microbiological hand contamination among caregivers at a tertiary hospital. Methods: The participants of this study were 59 caregivers woring at a tertiary hospital. Data were collected from July 1 to 30, 2018. Data were analyzed using descriptive statistics, t-test, ANOVA, Scheffé test, Pearson's correlation coefficients and stepwise multiple regression by SPSS 23.0 Win program. Results: Multiple regression analysis revealed that factors influencing performance of healthcare-associated infection control were awareness (β=.63, p<.001) and the experience of infection-related education (β=-3.40, p=.042). Regression equations describing the performance of healthcare-related infection control were found to be appropriate (F=27.29, p<.001) and accounted for 68% of variance. Factors affecting the degree of microbiological hand contamination were work experience (β=-0.28, p=.026) and healthcare-related infection performance (β=-0.28, p=.029). A regression equation describing the microbiological hand contamination was appropriate (F=6.10, p=.004) and accounted for 42% of variance. Conclusion: The findings of this study suggest that it is necessary to increase performance of healthcare-associated infection control by caregivers. Also, educations for preventing healthcare-associated infection and guidelines for increasing compliance with healthcare-associated infection control are recommended to improve performance of healthcare-associated infection control.

Apple (Malus domestica) is one of the most economically important fruits in Korea. But virus infection has decreased sustainable production of apple and caused the serious problems such as yield loss and poor fruit quality. Virus or viroid infection including Apple chlorotic leaf spot virus (ACLSV), Apple stem pitting virus (ASPV), Apple stem grooving virus (ASGV), Apple mosaic virus (ApMV) and Apple scar skin viroid (ASSVd) has been also reported in Korea, furthermore, its damages and economic losses have increased constantly. In our research, we tried to survey virus infection for commercial nursery trees of major apple cultivars, especially dwarfing rootstocks 'M.9' and 'M.26' as well as scions. Trees were collected from 11 locations which have produced a great amount of apple nursery stocks in Korea. Infection degree was investigated in apple cultivars, 'Hongro' and 'Fuji' using RT-PCR method. In the scion of cultivar 'Hongro', infection ratio of ACLSV, ASPV and ASGV were 100%, 81.8% and 100% respectively. In the rootstock of cultivar 'Hongro', infection ratio of ACLSV, ASPV, ASGV and ApMV were 90.9%, 81.8%, 100% and 9.1% respectively. In the scion of cultivar 'Fuji', infection ratio of ACLSV, ASPV and ASGV were 81.8%, 90.9% and 100% respectively. In the rootstock of cultivar 'Fuji', infection ratio of ACLSV, ASPV, ASGV and ApMV were 81.8%, 90.9%, 100% and 9.1% respectively. Infection of ASSVd was not detected in both cultivars. From our results, it was found that most of apple rootstocks and scions had multiple infections by apple viruses which have caused economic damage in fruit production.
