Purpose: This study aims to suggest an analysis model finding the relationship between building scale characteristics of Public-use facilities and infectious disease outbreaks around senior leisure welfare facilities and the features and their scopes where quarantine resources are to be concentrated. Methods: Reviewing previous studies found the user characteristics of senior leisure welfare facilities and scale characteristics of urban architectures. The data preprocessing was performed after collecting building data and infectious disease outbreak data in the analysis area. This study derived data for attributes of building size and frequency of infectious disease outbreaks in Public-use facilities around senior leisure welfare facilities. A computing algorithm was implemented to analyze the correlation between the building size characteristics and the infectious disease outbreak frequency as per the change of the spatial scope. Results: The results of this study are as follows: First, the suggested model was to analyze the correlation between the infection frequency and the number of senior leisure welfare facilities, the number of Public-use facilities, building area, total floor area, site area, height, building-to-land ratio, and floor area ratio varied as per the change of spatial scope. Second, correlation results varied between the infection frequency and the number of senior leisure welfare facilities, the number of Public-use facilities, building area, total floor area, site area, height, building-to-land ratio, and floor area ratio. Third, a negative correlation appeared in the analysis between the number of senior leisure welfare facilities and infection frequency. And positive correlations appeared noticeably in the study between the number of Public-use facilities, building area, total floor area, height, building-to-land ratio, and floor area ratio. Implications: This study can be used as primary data on the utilization of limited quarantine resources by analyzing the relationship between the Public-use facilities around the senior leisure welfare facilities and the spread of infectious diseases. In addition, it suggests that infectious disease prevention measures are necessary considering the spatial scope of the analysis area and the size of buildings.

Objectives : The purpose of this study was to improve the practice level on dental hygienists'infection prevention by examining the actual condition of dental hygienists'infection control and analyzing factors of having influence upon this. Methods : A questionnaire survey was carried out from July 18, 2011 to August 26 targeting dental hygienists who work at medical institutions where are located in Daegu, Busan and Ulsan Metropolitan Cities and Gyeongsangnam buk-do. After then, the following conclusions were obtained. Results : 1. As a result of surveying practice by item in the practice level of infection prevention, the items with high practice level in the management of infectious diseases were surveyed to be 12 months(89.6%) for health-checkup cycle and to be having experience of vaccination(78.0%) for hepatitis type B. The items with high practice level in the management and practice of washing hands were indicated to be in order of regularly paper towel(87.7%) and hands cleaning after regular medical examination(80.5%). In the item of the practice on wearing and managing individual protection equipment, regularly wearing(93.1%) rubber globes given washing implements was indicated to be high. 2. As a result of analyzing working career, working institution, working region, and practice level of infectious-disease management, the appearance of fulfilling infection control guidelines at medical institution and the experience of education for infection control were indicated to have difference depending on working institution. Regularly health checkup was indicated to have difference depending on respondents' working career and working institution. 3. The whole average in the practice level of infection prevention according to working career, working institution, and working region was indicated to be 2.55 out of 3-point perfection. 4. Wearing latex gloves was indicated to have statistically significant difference depending on working institution(p<0.001) and working region(p<0.001). The exchange of latex gloves every patient and the use of paper apron had statistically significant difference depending on working region(p<0.001). 5. As a result of comparing the frequency of using protection equipment for preventing infection according to the management of infectious diseases, the statistically significant difference was shown depending on the appearance of infection control guidelines at medical institution(p<0.001), the appearance of having experience of health checkup(p<0.01), and the appearance of having experience of vaccination for hepatitis type B(p<0.05). Conclusions : The above-mentioned findings showed that the denture satisfaction of the denture-wearing senior citizens was linked to their subjective oral health awareness. Therefore it will be possible to improve denture-wearing elderly people's quality of life when oral health plans geared toward boosting their denture satisfaction are carried out.

본 연구는 치과의원에 근속 중에 있는 치과위생사 142명을 대상으로 건강신념과 치과감염관리에 대한 중요도와 수행도와의 관련요인을 분석한 결과는 다음과 같다. 감염관리를 위한 수행도는 감염관리에 대한 교육경험이 있고, 감염성 질환에 관한 문진을 '항상' 하는 경우, 하루 평균 내원하는 환자 수가 50명 미만인 군에서 마스크와 라텍스 장갑의 착용률이 가장 높았다. 감염관리의 유익성과 행동의도가 높을수록, 개인방호용구의 중요성을 인지하고, 보호안경의 착용과 코로나-19 발생 이후 마스크 교체빈도가 높을수록 수행도는 증가하였다. 본 연구의 제한점으로는 편의추출로 조사지역과 대상이 국한되어 있어 연구결과를 일반화하기는 어려우며, 치과위생사의 감염관리 인식도에 초점을 맞춰 실제 치과에서 이루어지는 감염관리 현황을 세밀하게 조명하지 못했다. 연구결과를 고려해 볼 때, 감염관리에 대한 중요성과 인지된 유익성을 높이고 장애성을 낮춘다면 감염관리 수행도가 높아질 것으로 사료된다.

Background: The aim of this study was to assess clinical factors associated with Helicobacter pylori positivity and to evaluate the incidence of gastric carcinoma in first-degree family members of infected patients. A total of 580 patients (mean age:$38{\pm}17$) with gastrointestinal complaints underwent C-14 urea breath test (UBT). Patients were grouped as: Group-1, untreated patients (n:384); and Group-2, patients who previously treated with eradication triple therapy (n:196). C-14 UBT was performed 1-2 months after the completion of eradication therapy. Associations of H pylori positivity with age, gender, ABO and Rhesus groups, smoking, dietary habits, and history of gastric cancer in first-degree family members were evaluated. The frequency of H pylori positivity was significantly higher in group-1 (58%) compared to group-2 (20%), p=0.001. There were no correlations between H pylori positivity and age, gender, ABO groups, Rhesus subgroups, smoking and dietary habits in both patient groups. The frequency of gastric cancer in family members was significantly higher in patients with H pylori infection among group-1, compared to infected patients among group-2 (56% vs. 28.6% respectively, p=0.03). We observed a significant association between H pylori positivity and the presence of gastric cancer in first-degree relatives of group-1 patients. Our results provide some confirmation of the presence of a link between gastric cancer development and H pylori. C-14 UBT is a sensitive, reliable and a widely recommended test for the detection of H pylori infection and recurrence. We suggest that detection and eradication of H pylori may contribute to a reduced risk of gastric cancer in the family members of infected patients.

Babesiosis is an emerging tick-borne disease in humans worldwide; however, little is known about the frequency of infection or prevalence of this disease in other parts of the world, excluding North America. In this study, we aimed to investigate Babesia microti infection frequency in a human population in Mongolia. One hundred blood samples were collected from stock farmers living in Khutul city of Selenge province, Mongolia. The sera and DNA from blood samples were evaluated for the presence of B. microti infection by using indirect fluorescent antibody (IFA) tests and PCR. The positive detection rates obtained using the IFA tests and PCR assays were 7% and 3%, respectively. This study is the first to detect of B. microti infections based on antibody seroprevalence or PCR assays for the presence of B. microti DNA in a Mongolian population.

Toxoplasmosis, a neglected tropical disease caused by the protozoan parasite Toxoplasma gondii, occurs throughout the world. Human T. gondii infection is asymptomatic in 80% of the population; however, the infection is life-threatening and causes substantial neurologic damage in immunocompromised patients such as HIV-infected persons. The major purpose of this study was to investigate the seroprevalence of T. gondii infection in subjects infected with HIV/AIDS in eastern China. Our findings showed 9.7% prevalence of anti-T. gondii IgG antibody in HIV/AIDS patients, which was higher than in intravenous drug users (2.2%) and healthy controls (4.7%), while no significant difference was observed in the seroprevalence of anti-Toxoplasma IgM antibody among all participants (P>0.05). Among all HIV/AIDS patients, 15 men (7.7%) and 10 women (15.9%) were positive for anti-T. gondii IgG antibody; however, no significant difference was detected in the seroprevalence of anti-Toxoplasma IgG antibody between males and females. The frequency of anti-Toxoplasma IgG antibody was 8.0%, 13.2%, 5.5%, and 0% in patients with normal immune function ($CD4^+$ T-lymphocyte count ${\geq}500cells/ml$), immunocompromised patients (cell count ${\geq}200$ and <500 cells/ml), severely immunocompromised patients (cell count ${\geq}50$ and <200 cells/ml), and advanced AIDS patients, respectively (cell count <50 cells/ml), while only 3 immunocompromised patients were positive for anti-T. gondii IgM antibody. The results indicate a high seroprevalence of T. gondii infection in HIV/AIDS patients in eastern China, and a preventive therapy for toxoplasmosis may be given to HIV/AIDS patients based on $CD4^+$ T lymphocyte count.

The aim of this study was to assess the usefulness of PCR for diagnosis of Trichomonas vaginalis infection among male patients with chronic recurrent prostatitis and urethritis. Between June 2001 and December 2003, a total of 33 patients visited the Department of Urology, Hanyang University Guri Hospital and were examined for T. vaginalis infection by PCR and culture in TYM medium. For the PCR, we used primers based on a repetitive sequence cloned from T. vaginalis (TV-E650). Voided bladder urine (VB1 and VB3) was sampled from 33 men with symptoms of lower urinary tract infection (urethral charge, residual urine sensation, and frequency). Culture failed to detect any T. vaginalis infection whereas PCR identified 7 cases of trichomoniasis (21.2%). Five of the 7 cases had been diagnosed with prostatitis and 2 with urethritis. PCR for the 5 prostatitis cases yielded a positive 330 bp band from bothVB1 and VB3, whereas positive results were only obtained from VB1 for the 2 urethritis patients. We showed that the PCR method could detect T. vaginalis when there was only 1 T. vaginalis cell per PCR mixture. Our results strongly support the usefulness of PCR on urine samples for detecting T. vaginalis in chronic prostatitis and urethritis patients.
