Purpose: To investigate the spatial distribution of diabetes-related lower limb amputations and analyze the relationship between the spatial distribution of diabetes-related lower limb amputations and regional factors. Materials and Methods: This study was performed based on the data from the Korean Health Insurance Review and Assessment Service, in 2016. The unit of analysis was the administrative districts of city·gun·gu. The dependent variable was the age- and sex-adjusted incidence of diabetes-related lower limb amputations and the regional variables were selected to represent two aspects: socioeconomic factors, and health and medical factors. Along with traditional ordinary least square (OLS) regression analysis, geographically weighted regression (GWR) was applied for spatial analysis. Results: The age- and sex-adjusted incidence of diabetes-related lower limb amputation varied according to region. OLS regression showed that the incidence of diabetes-related lower limb amputation had significant relationships with the health and medical factors (number of healthcare institution and doctors per 100,000 population). In GWR, the effects of regional factors were not consistent. Conclusion: The spatial distribution of the incidence of diabetes-related lower limb amputations and the effects of regional factors varied according to the regions. The regional characteristics should be considered when establishing health policy related to diabetic foot care.

The purpose of this study is to identify the nature of the patient service quality of health center, and based on that, to examine the relationship of health center visitor's perceived quality and overall satisfaction. Data were collected on the basis of 'the 3rd Regional Health Care Planning' operated by Rural Health Care Service Technology Aid Task-force Team(RHCSTAT), Ministry of Health and Welfare. Basically, the Manual of 3rd Regional Health Care Planning is composed of structure, process, and outcome measurement indicators. Of these indicators, 21 patient satisfaction questions as outcome indicators are used in this study. The samples are 3,530 patients who visited 80 health centers all of the nation. First, the reliability and validity of patient service quality items was evaluated. Second, the descriptive statistics of health service quality are calculated. Third, through the T-test and ANOVA, the differences of patient satisfaction by responder's general characteristics are compared. In final, to explore the relationship of service quality and overall satisfaction, multiple regression analysis was used. This study shows firstly, the dimension of patient service quality was categorized into 3 dimensions, that is, facilities and environment, staff kindness, and access convenience. Secondly, the reliability and validity of patient service quality items was satisfied. Thirdly, the mean score of staff kindness factors are high in contrast to the facilities and environment. And in regard to the overall satisfaction, the mean score is more higher in Daegu region, County type health center, male group, and upper 65 age group than comparison groups. Lastly, as a result of multiple regression analysis, the effect of patient's perceived service quality, especially, appropriateness of billing time(Beta=0.190) and of reservation time(Beta=0.132) are statistically significant(P<0.01). In conclusion, to satisfy the health need of community people and improve the service quality of the health center, the efforts for the access convenience might be needed. Additionally, the enlargement on health center space and supply of new medical equipment is urgent for the patient satisfaction.

In this research we report the significant contribution of the as-spun multi-walled carbon nanotube (MWCNT) on the x-ray images formation using a low tube voltage x-ray source. The MWCNT, which was used for the fabrication of the spun CNT, was grown using a microwave plasma-enhanced chemical vapor deposition machine. Electrical-optics simulation software was utilized to determine the electron field emission trajectory of the triode-structure-as-spun CNT-based x-ray source. It was shown that a significant amount of converging electrons hit the target anode producing a clear x-ray image. These x-ray images where produced at a small amount of anode current of 0.67 mA at a tube voltage of 5 kV with the gate voltage of 0 V. Also, comparisons of the radiographs at various exposure times of the sample where analyzed with and without an x-ray dose filter. Results showed that spatially-resolved images were formed using the as-spun CNT at a low tube voltage with a $54-{\mu}m$ Al x-ray filter. This study can be used for low-voltage medical applications.

In this study, we investigated the effect of egg yolk lipids (EYL) on collagen ($10\;{\mu}g/ml$)-stimulated platelet aggregation in vivo. Dietary EYL significantly inhibited collagen-induced platelet aggregation, in addition, increased the formation of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), intracellular $Ca^{2+}$-antagonist as aggregation-inhibiting molecules, in collagen-stimulated platelets. These results suggest that EYL inhibits the collagen-induced platelet aggregation by up-regulating the cAMP and cGMP production. On the other hands, prothrombin time (PT) on extrinsic pathway of blood coagulation was potently prolonged by dietary EYL in vivo. These findings suggest that EYL prolongs the internal time between the conversion of fibrinogen to fibrin. Accordingly, our data demonstrate that EYL may be a crucial tool for a negative regulator during platelet activation and blood coagulation on thrombotic diseases.

Purpose: This study is to present basic data and standards for calculating the space composition and area required when planning a neonatal intensive care unit. Methods: Review domestic and foreign facility standards and regulations related to the current neonatal intensive care unit, select a regional neonatal intensive care center designated by the Ministry of Health and Welfare as a case hospital, and organize a space program for the construction plan of the neonatal intensive care unit through analysis of characteristics such as facility size and function composition. Results and Implications: The size, facility area, and detailed room composition characteristics of the neonatal intensive care unit in Korea were confirmed, and essential rooms and appropriate areas were derived when planning the construction of the neonatal intensive care unit. Korea's legal facility standards related to neonatal intensive care units are lower than the actual hospital status and overseas standards, and the facility standards of the medical law need to be improved.

Background: Genetic factors play important roles in the pathogenesis of human cancer. A recent genome wide association study (GWAS) identified an association between the rs2294008 polymorphism of the prostate stem cell antigen (PSCA) gene and bladder cancer risk in Caucasians. The aim of this study was to determine whether the rs2294008 polymorphism is similarly associated with bladder cancer susceptibility in a Korean population. Materials and Methods: We conducted a case-control study of 411 bladder cancer patients and 1,700 controls. Results: The frequencies of the CC, CT, and TT genotypes of the rs2294008 polymorphism were 16.9, 54.0, and 28.8% in bladder cancer patients and 24.4, 48.1, and 27.5% in controls, respectively. We found that the combined CT/TT genotypes were associated with a significantly increased risk of bladder cancer (OR CT/TT =1.58, 95% CI= 1.15-2.17), compared with the CC genotype. Smoking habits, tumor grade and tumor stage did not modify the association between rs2294008 and the risk of bladder cancer. Conclusions: Our study showed that the rs2294008 polymorphism in the PSCA gene is associated with the risk of bladder cancer in a Korean population, providing evidence that it may contribute to bladder carcinogenesis regardless of ethnicity.

Objective : Leukoaraiosis (LA) has been suggested to be related to the poor outcome or the occurrence of symptomatic intracerebral hemorrhage (sICH) after acute ischemic stroke. We retrospectively investigated the influences of LA on long-term outcome and the occurrence of sICH after thrombolysis in acute ischemic stroke (AIS). Methods : In this study, we recruited 164 patients with AIS and magnetic resonance image (MRI)-detected thrombolysis. The presence and extent of LA were assessed using the Fazekas grading system. The National Institutes of Health Stroke Scale score was used to assess the baseline measure of neurologic severity, and the modified Rankin Scale score assessment was used up to 1 year after thrombolysis. Results : Of 164 subjects, 56 (34.2%) showed LA on MRI. Compared to the 108 patients without LA, the patients with LA were of much older age (p<0.01), had a higher prevalence of hypertension (p<0.01), and had a much poorer outcome at 90 days (p=0.05) and 1 yr (p=0.01) after thrombolysis. There were no significant differences in sICH between patients with and without LA on MRI. In univariate analysis for the occurrence of poor outcome at 90 days after thrombolysis, the size of ischemic lesion on diffusion weighted images (DWI), [odds ratio (OR), 1.03; 95% confidence interval (95% CI), 1.01-1.04; p<0.01], recanalization (OR, 0.03; 95% CI, 0.01-0.10; p<0.01), sICH (OR, 12.2; 95% CI, 1.54-95.8), neurologic severity (OR, 1.17; 95% CI, 1.09-1.25; p<0.01), blood glucose level (OR, 1.01; 95% CI, 1.00-1.02; p=0.03), and the presence of LA on MRI (OR, 2.01; 95% CI, 1.04-3.01; p=0.04) were statistically significant. In multivariate analysis, neurologic severity (OR, 1.14; 95% CI, 1.04-1.24; p<0.01), recanalization (OR, 0.03; 95% CI, 0.01-0.11; p<0.01), lesion size on DWI (OR, 1.02; 95% CI, 1.01-1.03; p=0.02), serum glucose level (OR, 1.01; 95% CI; 1.01-1.02; p=0.03), and the presence of LA on MRI (OR, 3.2; 95% CI, 1.22-8.48; p<0.01) showed statistically significant differences. These trends persisted up to 1 yr after thrombolysis. Conclusion : In this study, we demonstrated that the presence of LA on MRI might be related to poor outcome after use of intravenous tissue plasminogen activator in AIS.

목 적 : 최근 임상 적용이 늘어나는 citrate 항응고요법은 전신적 출혈성 경향을 증가시키지 않으나 여러 가지 대사 이상을 유발할 가능성이 있다. 저자들은 소아에서 칼슘포함투석액을 이용한 citrate 항응고요법의 효과 및 문제점을 알아보고자 하였다. 방 법 : 2002년 3월부터 2004년 10월까지 서울아산병원에서 CRRT를 시행받은 28명의 소아를 대상으로 후향적으로 의무기록을 검토하였다. 항응고요법의 종류에 따른 필터 수명을 비교하고 citrate 항응고요법을 시행한 환아들에서 CRRT 시작 시점과 시행 48시간 후의 전해질 검사 결과를 분석하였다. 결 과 : 28명의 환아들 중 모두 5명에서 citrate를 사용하였으며 이중 4명에서 출혈성 경향이 동반되어 있었다. Citrate를 사용하였을 때 필터 평균 수명은 1.60$\pm$0.72일로 CRRT 시행 중 출혈성 합병증은 없었다. 치료 전후의 Pf, aPTT, sodium, t$CO_{2}$, iCa은 차이가 없었으나 치료 48시간 후 총 Ca은 증가하였다. 필터 후 iCa 목표를 통상적으로 적용되는 0.25-0.39 mmol/L로 하였을 때 5례에서 모두 citrate 주입량이 증가하였으며 Ca 주입량은 감소하였다. 결 론 : 칼슘포함투석액을 이용한 citrate 항응고요법은 소아에서 출혈성 합병증이나 대사 이상을 유발하지 않고 안전하게 적용할 수 있는 방법으로 출혈성 경향이 동반된 환아의 CRRT에서 유용하게 쓰일 수 있다. 다만 현재 통상적으로 적용되는 값보다 필터 후 칼슘의 목표를 상향 조정하는 것이 추천된다.
