Background: The purpose of this study was to analyze the relationship between the regional characteristics and the age-adjusted cardio-cerebrovascular disease mortality rates (SCDMR) in 229 si·gun·gu administrative regions. Methods: SCDMR of man and woman was used as a dependent variable using the statistical data of death cause in 2017. As a representative index of regional characteristics, health behavior factors, socio-demographic and economic factors, physical environment factors, and health care factors were selected as independent variables. Ordinary least square (OLS) regression and geographically weighted regression (GWR) were performed to identify their relationship. Results: OLS analysis showed significant factors affecting the mortality rates of cardio-cerebrovascular disease as follows: high-risk drinking rates, the ratio of elderly living alone, financial independence, and walking practice rates. GWR analysis showed that the regression coefficients were varied by regions and the influence directions of the independent variables on the dependent variable were mixed. GWR showed higher adjusted R² and Akaike information criterion values than those of OLS. Conclusion: If there is a spatial heterogeneity problem as Korea, it is appropriate to use the GWR model to estimate the influence of regional characteristics. Therefore, results using the GWR model suggest that it needs to establish customized health policies and projects for each region considering the socio-economic characteristics of each region.

Breast cancer is the most common cancer in Jamaican women. Locally advanced breast cancer (LABC) is associated with aggressive biology and poor prognosis, and has a predilection for African-American women. In this retrospective review, we assessed the prevalence of LABC as a breast cancer presentation in a population of mainly Afro-centric ethnicity, and determined disease characteristics and response to pre-operative chemotherapy. LABC was prevalent (20%), and had a low pathological response rate to pre-operative chemotherapy, with a high risk of disease recurrence. Increased utilization of breast cancer screening may help detect cancer at less advanced stages, and optimizing pre-operative chemotherapy is recommended to improve response rates and ultimately survival.

A disease causing fruit rot and leaf and vine blight on watermelon was found in Euseong in July, 1991 and in Bonghwa, Kyungpook province in August, 1993. Abundant zoosporangia characteristics of Phytophthora capsici were formed on the surface of the infected fruits. The zoosporangia were ovoid to ellipsoid, tapering to the base and with conspicuous papilla. The fungus isolated from the infected fruits was pathogenic on seedlings of watermelon, pumpkin, and pepper. The morphological characteristics and host range agreed with those of P. capsici. The watermelon disease caused by P. capsici was reported long time ago in Japan and America but rot yet in Korea. Thus, the disease on watermelon caused by P. capsici is reported as a new record in Korea.

In this study, we investigated mechanical properties and surface characteristics of Ti-25Ta-xHf alloys. The samples were manufactured for composition of Ti-25Ta-xHf(x=0 to 15 wt. %) alloys. Each alloy was melted twenty times in an arc-melting vacuum furnace. The microstructural phases and phase transformation of Ti-25Ta-xHf alloys were identified with the aid of an XRF, XRD and DSC. And mechanical properties were investigated using Vickers hardness, nanoindentation, and tensile test.

Black spot of sweet persimmon, caused by Alternaria alternata, occurred in an orchard in Gyeongnam province, Korea in 2012. The symptom was appearance of 0.5 to 4 cm black spots on the surface of fruit. The pathogen was isolated from flesh of disease lesions. The causal agent was identified as A. alternata by morphological characteristics and sequencers of the internal transcribed spacer (ITS) 1 and ITS4 regions of rRNA. Artificial inoculation of the pathogen resulted in development of disease symptoms and the re-isolated pathogen showed characteristics of A. alternata.

Although many diseases could be treated by the development of modern medicine, there are some incurable diseases including brain cancer, Alzheimer disease, etc. To study human brain cancer, various animal models were reported. Among these animal models, mouse models are valuable tools for understanding brain cancer characteristics. In spite of many mouse brain cancer models, it has been difficult to find a new target molecule for the treatment of brain cancer. One of the reasons is absence of large animal model which makes conducting preclinical trials. In this article, we review a recent study of molecular characteristics of human brain cancer, their genetic mutation and comparative analysis of the mouse brain cancer model. Finally, we suggest the need for development of large animal models using somatic cell nuclear transfer in translational research.

Dental treatment for the disabled should be a customized that considers the characteristics and degree of cooperation of each disabled patient. There are additional considerations during implant treatment and tooth extraction in disabled patients. Since some brain lesion disorder or cardiac disease patients may be taking antiplatelet or anticoagulant medications, it is necessary to evaluate whether these medications should be discontinued before an invasive procedure. Precautions should be taken for patients with heart valve disease considering the risk of infective endocarditis, especially during invasive dental procedures. Moreover, disabled patients may have difficulty in following instructions and cautions. There are specific considerations for each stage of implant treatment in disabled patients. In the case of patients who are in the pre- or post-transplant state, it is necessary to assess their general condition and oral disease due to the risk of infection. Since disabled patients with various systemic diseases may visit the dental clinic, it is important to understand their characteristics and treatment process in order to flexibly adjust the dental treatment plan accordingly.

The purpose of this study was to investigate the spiritual well-being of hemodialysis patients and the correlation between spiritual well-being and demographic characteristics and disease related characteristics. The subjects for this study were 98 patients who were diagnosed as having chronic renal failure and were being treated at the hemodialysis units of three hospitals located in Seoul, Pusan and Taegu, Korea. Data were collected from October 27 1997 to November 15, 1997 by an investigator interviewing with a structured questionnaire. Palautizion and Ellison(1982)'s spiritual well-being scale was used after some modification. The results of this study are as follows ; To analyze the differences between demographic characteristics, spiritual well-being, and disease characteristics and the spiritual well-being, T-test and ANOVA were used. 1. There were statistically significant differences in spiritual well-being for the demographic characteristics of age (p=0.0145) religious affiliation(p=0.0001) and level of education(p=0.04). 2. There were statistically significant differences in spiritual well-being for the disease characteristics perceived health status (p=0.0014) and vigor(p=0.01) 3. The mean score for spiritual well-being in hemodialysis patients was 57.10 of a possible range of 22-88. Among the components of spiritual well-being, the mean score for religions well-being was 27.01 of a possible range 11-44, and for existential well-being 30.09 of a possible range of 11-44. 4. Correlation between general characteristics and spiritual well-being showed that there were significantly positive correlations for level of education(p=0.0036), perceived health status(p=0.0001), vigor(p=0.0036) and religion(p=0.0004)

The causes of liver disease in children and abnormal liver function test are more diverse than those in adult. Therefore, the first step to evaluate the liver disease is the understanding the liver disease and interpreting the appropriate liver function test in children. The characteristics of each test and various conditions which we encounter in outpatients settings will be discussed in this article, especially focused on elevation of aminotransferase level without identifiable causes.
