본 논문에서는 EPC Network의 응용 기술 분야에서 가장 중요한 기술로 연구되고 주목받고 있는 RFID를 활용하여 특수질병 감염환자를 효율적으로 관리할 수 있는 U-MAS (U-Medical Administrative Services)시스템을 설계하였다. U-MAS시스템은 질병관리본부에서 질병의 유형에 따라 감염환자들을 격리 수용과 치료, 회복, 퇴원, 격리병동 이탈 등을 집중 관리할 수 있도록 효율성을 증대시킬 수 있으며, 수작업과 단순한 컴퓨터 프로그램을 이용하는 현 수준의 질적 향상을 높이기 위해 RFID 태그를 이용하여 환자의 관리를 좀 더 면밀하고, 격리병동을 벗어나게 될 경우 관할 질병관리지역구에서 보다 빠르게 위치추적 등의 대응을 원활히 할 수 있도록 기여하는데 목적이 있다. 먼저, EPC 네트워크의 관련 기술과 모바일 RFID 시스템에 대한 관련 연구를 기술하고, U-MAS 시스템 설계를 제안한다. 제안된 U-MAS 시스템을 활용할 경우 전염성 질병환자에 대한 모니터링과 격리병동에 있는 환자가 무단으로 이탈하였을 때 위치추적에 소요되는 시간을 단축시키는 질병관리업무의 효율성을 개선할 수 있는 기대 효과를 제시하였다.

Purpose: Authors suggest a new alternative of preparedness capabilities for health care institutes to react to the new types of communicable diseases and the pandemic situations through the quality improvement and advancement of Negative Pressure Isolation Stretcher (NPIS). Methods: We employed FOCUS-PDCA, a representative quality improvement model. First, we identified and materialized necessary components of existing NPIS to be improved. Second, we fabricated an advanced NPIS prototype. Third, we carried out a performance test by the accreditation institute and an empirical evaluation at the communicable diseases trauma center, to locate the improvement pain points of the prototype. Finally, we draw a conclusion on quality improvement points to be considered during the production stage. Results: The suggested, NPIS outperforms the existing one in terms of communicable disease controls, patient treatments and the safety during the patient transfer, and the ease of use. Additionally, the suggested NPIS turns out to be a proper alternative to satisfy the requirements of long range transfer of patients with communicable disease. Conclusion: Authors developed a quality improved, NPIS prototype. There are several points that still remain to be improved. Additionally, we expect that the concurrent use of the suggested NPIS with the existing one will fortify the preparedness capabilities on reacting to the communicable diseases.

Purpose: This study was a within subject repeated pretest-posttest design done to compare the effect of disinfection and the degree of MRSA(Methicillin- resistant staphylococcus aureus) isolation from hand disinfectant in ICU nurses. Method: Out of the total internal medicine/surgery ICU nurses at a university hospital in Seoul, 29 female nurses who were participating in direct patient care were participants in this study. After collection of samples, Staphylococcus aureus and MRSA were isolated from the palms, nails and nasal cavities of the nurses according to disinfectants (soap and beta-scrub). Results: The effect of disinfection was greater in the beta-scrub group than in the soap group, and the effect of disinfection on palms was higher in the beta-scrub group than in the soap group. As for the degree of MRSA isolation, there was more isolation in palms in the soap group than in the beta-scrub group but there was no difference in the degree of MRSA isolation from the hand disinfectant in nails and nasal cavities. Conclusion: Beta-scrub showed a superior prolonged effect against transient bacteria compared with soap. Further, to reduce MRSA infection, we recommend interventions focused on these aspects.

Objectives : This study was performed to investigate the mumps transmission control status and inapparent infection rate among middle and high school students in Daegu City during a mumps outbreak. Methods : Nine schools (two middle schools and seven high schools), which reported a number of mumps cases between 2007 and 2008 were selected for investigation. During March-May 2008, a standard questionnaire was distributed to gather information about case identification, instructed isolation measure, isolation status of mumps cases and related factors, and outdoor activities of nonisolated mumps case. Inapparent infection rate was estimated by serum mumps IgM and IgG antibodies status and self-reported mumps symptoms in three of the nine schools. Results : Among 2,560 respondents, more than half of students answered that they did not receive instructions in mumps transmission control measures during the outbreak. Among the 327 mumps cases identified by the questionnaire, 131 cases (40.1%) were considered as isolated and the isolation rates were significantly different among schools, grades, and gender. Of the non-isolated cases, 88.3% continued attending school. Inapparent mumps infection rates were between 56.3% and 70.2%. Conclusions : Mumps transmission control was inadequate to control the mumps outbreak. Although high inapparent infection rate would mitigate the transmission control effect of case isolation, this measure is fundamental for infection control. The reasons of this inadequate status need to be explored to develop an effective intervention strategy.

This study analyzes the content of YouTube Vlog videos created by patients of Coronavirus disease 2019 ("COVID-19") in South Korea and viewer comments on those videos. As this new infectious disease started to sweep the world in late 2019 and early 2020, the public started facing fear and uncertainty stemming from the lack of sufficient and accurate information about the virus. At the same time, as COVID-19 patients in South Korea were treated in isolation to prevent the spread of the virus, the patients themselves were experiencing anxiety and exclusion from the society. During this period, there was an increase in YouTube Vlog videos created by the patients in which they shared their experiences going through the treatment and recovery processes. To understand how these YouTube Vlog videos were being used by the patients to connect with the society and seek support in a state of isolation and anxiety, this study conducted a qualitative multi-case analysis of three sample YouTube Vlog video channels to analyze their content, as well as a lexicon-based sentiment analysis of viewer comments to understand the experiences and reactions of viewers. The patients' YouTube Vlog videos showed that they shared similar stages of progress, despite each emphasizing a different main theme. Overall, the tone of the viewer comments became increasingly positive over time, although with some variance among different patient cases and stages. The results confirmed that Vlogs of patients played a significant role in reducing the uncertainty around COVID-19 and strengthening social support for the patients. The findings of this study can improve an understanding of the psychological and behavioral aspects of patient experience in isolated treatment and the impact of shared communication among members of society in times of crisis.

Three Korean rapidly progressive periodontitis patient (R.P.P.) were examined for the isolation and identification of black-pigmented Bacteroides and Bacteroides gingivalis in the subgingival plaque. Black-pigmented Bacteroides and Bacteroides gingivalis were recovered from all three R.P. patients and the predominant isolates were Bacteroides intermedius followed by Bacteroides gingivalis. The B. gingivalis isolated from subgingival plaque of rapidly progressive periodontitis patients were Gram-negative pleomorphic rods and each produced brown to black colonies on blood agar plate supplemented with 5% rabbit 5ug/ml haemin, 0.5ug/ml of menadione and 40ug/ml of Kanamycin. The B. gingivalis isolated were fermented none of Glucose, Sucrose, Lactose, Esculin and Cellobinose and produced indole. Isolation and identification of Bacteroides gingivalis in Korean R.P. patients can be contributed to the research on the pathogenesis of Korean periodontal disease.
