The purpose of this study was to investigate the effects of smart phone video educational program on disease-related knowledge and anxiety in patients with coronary artery disease. A quasi-experimental study used a non-equivalent control group pre-post test design. A smart phone video educational program was developed and offered to the experimental group. Participants were drawn from a inpatient ward. Twenty eight were selected for the experimental group while 30 were assigned to a control group. The results of this study were as followed: Disease-related knowledge in the experimental group showed a significant increase after smart phone video education compared with the control group. But the score of anxiety did not show a significant difference between experimental and control group. Thus, it is necessary to develop interventions considering both educational and psychological factors at the same time for the patients with coronary artery disease.

The purpose of this study was to use the data from the Health Insurance Review and Assessment Service to analyze the disagreement in disease coding given by different medical institutions on the same disease of the same patient and provide basic data that could help improve the quality of national public health statistics. 9,976,826 patients' data records from the Health Insurance Review and Assessment Service-National Patient Sample (HIRA-NPS) of 2014 were analyzed. The disagreement in disease coding differed by movement paths for medical institutions; the disagreement rate tended to increase when moving from a medical institution other than public health centers to a public health center and decrease remarkably when moving from a specialized general hospital to another. Therefore, this analysis of disagreement in disease coding among medical institutions suggests the need to supplement the system so that domestic medical institutions can realize consistent disease coding.

The progress of periodontal disease and the wound healing process after treatment result in alveolar bone bone change. So, detection of it is very important in the diagnosis and the radiograph of periodontal disease. Various effects have been made to assess the subtle alveolar bone change and digital subtraction radiography (DSR) has been reported to be the best method in evaluating it qualitatively and quantitatively. The present study was performed to estimate the detectable alveolar bone change qualitatively with digital subtraction radiography. For the in vitro study, 10 intraoral standard radiographs were taken from porcine dry mandible which a rectangular cortical bone chip of 0.1mm to 1.0mm thickness with 0.1mm increment was attached on the buccal surface. The radiographs without and with bone plates were reviewed at the same time by 10 observers and requested to detect the presence of cortical bone plates. Digital Subtraction radiograph was reviewed subsequently by using the DSR system(digital converter-256 grey-levels,DT 2851,Data Translation Co., U.S.A;IBM 386 ; CCD camera, FOTOVIX, Tamrom Co., Japan). The detectable thickness of cortical bone plate was O.4mm on the intraoral radiograph and 0.2mm on the subtaction images. For the human study, radiographs were taken from patients by using intraoral film holding device and aluminum reference wedge before and 3 month after bone graft and 1 week after osteoplasty. The grey level change was estimated in the subtraction images and calculated to aluminum equivalent thickness. The grey level of the grafted site was higher that that of healthy controls. Average grey levels of change on healthy controls were O.48mm aluminum equivalent. However, the amount of changes in grafted sites were 1.87mm aluminum thickness equivalent and in the site of osteoplasty were -1.49mm aluminum thickness equivalent. In conclusion, digital subtraction radiography was more effective in detecting as subtle change of alveolar bone than intraoral standard radiography. With the aid of quantitative analysis of digital subtraction radiography, alveolar bone resorption of apposition can be estimated during diagnosis and treatment of periodontally diseased patients.

The syndromic surveillance system is designed to identify illness clusters before diagnoses are confirmed and reported to public health agencies, to provide rapid public health response, and thereby to reduce morbidity and mortality. Korea Centers for Disease Control and Prevention (KCDC) has implemented the emergency department-based syndromic surveillance system. To design upgraded and enhanced functions of the current syndromic surveillance system in KCDC for the early warning of adverse disease events, we surveyed many papers. This paper describes the operation status of syndromic surveillance system in other countries and the improvement of the syndromic surveillance system in KCDC.

The purpose of this study is to investigate patients with Lou Gehrig's disease, their families, and their actual conditions of the disease, and to find the factors to alleviate caregiving burden and the needs of service. According to the study, the sociodemographic characteristics of the patients with Lou Gehrig's disease and their patients, the disease and caregiving, and activity support service didn't influence alleviation of caregiving burden. When the main caregiver of the patient was not a spouse, or graduated from high school and less, and when the disease was diagnosed initially, there was a difference in caregiving burden. Based on the results, this study suggested that it would be necessary to make medical support suitable to Lou Gehrig's disease and come up with a convergence policy to support personalized and specialized welfare service.

Purpose: The purpose of the study was to examine the related factors of quality of life (QOL) among middle-male with chronic liver disease. Method: The participants in this study were 110 patients with chronic liver disease who were recruited from the outpatient clinic of hospital. Between March and May 2014, data were collected through questionnaires and medical record review. Data analysis was performed using PASW (SPSS) 19.0 program, and one-way ANOVA, Pearson correlation coefficients, and enter multiple regression analysis. Results: The mean QOL of this study was 48.16/100. The significant correlates of QOL were anxiety-depression (${\beta}$=.33, p<.001), symptom experience (${\beta}$=.15, p=.001), health perception(${\beta}$=.31, p<.001), disease status(${\beta}$=.17, p=.022), spouse (${\beta}$=.23, p=.001), and these variables explained 68.6% of variance in QOL. Conclusion: The study suggests that psychological aspects are an important factor in explaining QOL of the middle-male with chronic liver disease. Screening and minimizing anxiety-depression could be effective strategies in enhancing QOL of middle-male with chronic liver disease.

This study is a review of research articles on the characteristics of probiotics. Probiotics are effective at ameliorating immune disease, alleviating glucose intolerance, and improving constipation and diarrhea. Furthermore, they have anticancer and antitumor effects, preventive effects against cardiovascular disease, antidiabetic effects, antioxidant effects, antibacterial effects, and they produce useful metabolites. It has been demonstrated that oral probiotics are effective in eliminating halitosis and forming a favorable oral ecosystem, by creating an environment that is not readily inhabited by harmful bacteria, such as Streptococcus mutans, which produces lactic acid and causes tooth decay, or Porphyromonas gingivalis, which causes gum disease.As a result, oral probiotics are being considered not only as therapeutics against diseases, but also as preventive agents for the maintenance of a healthy oral balance. In spite of some limitations, clinical trials are currently underway, and this study can provide evidence to support the use of probiotics to improve oral health conditions, including dental caries, periodontal disease, and Candida colonization.

Raynaud's syndrome causes discolorization, ischemic claudication(pain) and necrosis of the digits through insufficiency in the circulation which is induced by intermittent spasms of the digital arteries. From January, 2002 to December, 2004, 10 patients were surgically treated for Raynaud's syndrome. 9 patients were female and 1 patient was male. 2 patients showed unilateral involvement, 8 patients were operated on both hands. 6 patients had necrotic changes on the finger tips due to the disease. Ages ranged from 21 to 60 with an average of 39.1. Ischemic pain, discolorization, and cold intolerance of the digits were the common symptoms. All patients were evaluated with color doppler before the surgery. Two different procedures were applied according to the severity of the disease: Patients with decreased circulation received, what we call a limited digital sympathectomy, i.e. stripping of the adventitia of the ulnar, radial and common digital arteries. An extended procedure, radical digital sympathectomy, was performed on patients with a complete block of circulation. Stripping of the adventitia in these patients also involved the proper digital arteries. Symptoms like discolorization, ischemic pain, and cold intolerance improved immediately after the surgery. The patients did not suffer from pain even with exposure to cold weather. We conclude that digital sympathectomy could improve the symptoms in Raynaud's patients who do not respond to conservative treatment such as calcium channel blocker and other vasodilators.

This paper is concerned with the development of a simple digital stethoscope system for diagnosis of cardiac disorders. This system consists of an electronic stethoscope, IC sound recorder and a notebook computer. The cardiac sound is easily acquired by the electronic stethoscope and then recorded in IC memory stick so that the digital cardiac signal can be simply transmitted to the computer for signal display, disease diagnosis, and personal history record. A software is built with functions displaying the sound graphically and replaying the sound clearly. Further, a neural network recognition system for automatic diagnosis of cardiac disorders is also added to the software.

There is no exact standard of detecting pulmonary tuberculosis(TB) in digital image of simple chest radiography. In this study, I experimented on the principal components analysis(PCA) algorithm in the past and suggested six other parameters as identification of TB lesions. The purpose of this study was to develop and test computer aided diagnosis(detection) method for the detection and measurement of pulmonary abnormalities on digital chest radiography. It showed comparatively low recognition diagnosis rate using PCA method, however, six kinds of texture features parameters algorithm showed similar or higher diagnosis rates of pulmonary disease than that of the clinical radiologists. Proposed algorithms using computer-aided of texture analysis can distinguish between areas of abnormality in the chest digital images, differentiate lesions having pulmonary disease. The method could be useful tool for classifying and measuring chest lesions, it would play a major role in radiologist's diagnosis of disease so as to help in pre-reading diagnosis and prevention of pulmonary tuberculosis.
