A study on the status of death in rural area was conducted during the period from July '75 to August '75. 1,225 families and 8,067 population (4,124 male, 3,943 female) had been lived and 149 events of death since 5 years before study were occurred in survey area, Nammyon, Hwasoongun, Chonnam. The summarized results were as follows: 1. Quinquennial death rate was 3.7 (5.2 for male, 2.1 for female). 2. In respect of age group, the highest group was over 70 years old group (age at death, 30.8% of total death). High age groups (over 50 years old) occupied 71.1% of total death and death rate in these groups were higher in male than female. Child death (0-4 years old) occupied 7.4% of total death and infant death rate was higher in female than male. 3. Duration of sickness before die was highest in 1 to 12 months (39.6%) 4. The most frequent cause of death was disease of digestive system (12.1%). Other important causes were disease of circulatory system (10.7%), disease of respiratory system (9.4%) and infectious and parasitic disease (4.7%). Disease of digestive system was the most frequent cause of death in male (14.0%) and disease of respiratory system was the most frequent cause in female (9.5%).

Electrocardiogram being the recording of the heart's electrical activity provides valuable clinical information about heart's status. Many re-searches have been pursued for heart disease diagnosis using ECG so far. However, electrocardio-graph uses foreign diagnosis algorithm due to inaccuracy of diagnosis results for a heart disease. This paper suggests ECG data collection, data preprocessing and heart disease pattern classification using data mining. This classification technique is the FB(Frequent pattern Bayesian) classifier and is a combination of two data mining problems, naive bayesian and frequent pattern mining. FB uses Product Approximation construction that uses the discovered frequent patterns. Therefore, this method overcomes weakness of naive bayesian which makes the assumption of class conditional independence.

Objectives: This study investigated health behavior and nutritional status according to the presence or absence of periodontal disease using data from the Sixth National Health Nutrition Survey. Methods: Data from the 2013-2015 National Health Nutrition Survey were analyzed by frequency analysis, chi-square test, and Pearson's correlation analysis using SPSS 21.0. Results: Periodontal disease was more frequent in the group of patients who perceived that their subjective health status was "very bad" or were underweight according to the BMI classification. In men, periodontal disease occurred more frequently in those who were taking calcium (p<0.05), and periodontal disease occurred more frequently in the age group of 20-39, regardless of sex (p<0.05). In women, periodontal disease was less frequent in the group taking vitamin A. In both men and women, the presence of periodontal disease correlated with high fasting blood sugar and glycated hemoglobin levels. Conclusions: A customized program should be developed for each patient to identify factors that affect the relationship among periodontal disease, nutrient intake, and blood parameters. Such information will help improve the oral health of the population.

Objective : This study was performed to investigate the prevalence of otolaryngology and respiratory diseases and characteristics of the outpatients who had visited Chuncheon oriental medical hospital which located in Gangwon province with the diseases. Methods : We analyzed data from 627 patients, who had visited to the Department of ophthalmology & otolaryngology & dermatology of Chuncheon oriental medical hospital from November 1st, 2007 to May 31th, 2010. The data were analyzed and demonstrated by age, gender, season, period between the onset of disease and the first examination, times of treatment, and treatment methods. Results : The results of this study are summarized as follows. 1. Among the 627 outpatients, male patients outnumbered female patients, and the most frequent age group was 0-10 year-old group(24.9%) and it is followed by 31-40 and 41-50 year-old groups. The majority of outpatients, 79.7% of them were from Chuncheon, and Hongcheon and Gapyeong residents were respectively 4.7% and 3.8% of the patients. 2. The shares of outpatients by department were 47.4% in Rhinology disease, 29.8% in respiratory disease, 14.5% in Otology disease, and 8.3% in Laryngology disease. The seasons with the most frequent prevalence by department were spring and winter for otology group, autumn and spring for rhinology group, summer and spring for laryngology group, and winter and spring for respiratory disease group. Overall, most outpatients had visited the hospital for 1-5 times or 6-10 times. Acupuncture and herbal medicine were the most frequent treatment methods that these patients received. 3. The most prevalent diseases were rhinitis, common cold, tinnitus, and sinusitis. The most frequently visited age groups for tinnitus and hearing loss were 41-50 and 51-60 year-old groups, and for rhinitis and sinusitis 0-10 and 11-20 year-old groups. Irritation in larynx was almost evenly prevalent among 31-40, 41-50 and 51-60 age groups. Regarding the period between the onset of disease and the first medical examination, outpatients with tinnitus, rhinitis, sinusitis, and irritation in larynx came to the hospital after one year since the onset and outpatients with common cold first visited the hospital within one week since the onset of disease. Conclusions : This study shows that the most frequent diseases were rhinitis, common cold, sinusitis, tinnitus, and cough. In order to do better treatment for these diseases in the future, there is a need to investigate long-term, multifaceted studies, connected studies with other hospital in Gangwon province.

Purpose: This study was conducted to identify the job-related health problems of school teachers in Seoul area and investigate their disease management behavior. Methods: This study used the on-line survey to investigate frequent health problems and management behavior of teachers. And job-related diseases were identified using date from the National Health Insurance Corporation. Collected data were analyzed by descriptive statistics, t-test and ANOVA. Results: The frequent health problems of teachers were varicose veins, vocal cord disease and thyroid disease. And Job-related health diseases were varicose veins and vocal cord disease. These problems increased with career. 57.4% and 28.4% teachers in varicose veins and vocal cord disease did not do any management behavior to prevent or cure the disease. 56.8% teachers did not know how to prevent the diseases and 16.3% teachers did not practice even though they know the methods of prevention. Conclusion: Teacher's health examination should include varicose veins and vocal cord disease examination. And schools should try to offer various programs for preventing job-related health problems.

Mortality of domestic people from cardiovascular disease ranked second, which followed that of from cancer last year. Therefore, it is very important and urgent to enhance the reliability of medical examination and treatment for cardiovascular disease. Heart Rate Variability (HRV) is the most commonly used noninvasive methods to evaluate autonomic regulation of heart rate and conditions of a human heart. In this paper, our aim is to extract a quantitative measure for HRV to enhance the reliability of medical examination for cardiovascular disease, and then develop a prediction method for extracting multi-parametric features by analyzing HRV from ECG. In this study, we propose a hybrid Bayesian classifier called FP-based Bayesian. The proposed classifier use frequent patterns for building Bayesian model. Since the volume of patterns produced can be large, we offer a rule cohesion measure that allows a strong push of pruning patterns in the pattern-generating process. We conduct an experiment for the FP-based Bayesian classifier, which utilizes multiple rules and pruning, and biased confidence (or cohesion measure) and dataset consisting of 670 participants distributed into two groups, namely normal and patients with coronary artery disease.

Background: Chronic obstructive pulmonary disease (COPD) is now regarded as a heterogenous disease, with variable phenotypes. Acute exacerbation of COPD is a major event that alters the natural course of disease. The frequency of COPD exacerbation is variable among patients. We analyzed clinical features, according to the frequency of acute exacerbation in COPD. Methods: Sixty patients, who visited Gyeongsang National University Hospital from March 2010 to October 2010, were enrolled. Patients were divided into two groups, according to their frequency of acute exacerbation. Frequent exacerbator is defined as the patient who has two or more exacerbation per one year. We reviewed patients' medical records and investigated modified Medical Research Council (MMRC) dyspnea scale, smoking history and frequency of acute exacerbation. We also conducted pulmonary function test and 6-minute walking test, calculated body mass index, degree of airway obstruction and dyspnea and exercise capacity (BODE) index and measured CD146 cells in the peripheral blood. Results: The number of frequent exacerbators and infrequent exacerbators was 20 and 40, respectively. The frequent exacerbator group had more severe airway obstruction (forced expiratory volume in one second [$FEV_1$], 45% vs. 65.3%, p=0.001; $FEV_1$/forced vital capacity, 44.3% vs. 50.5%, p=0.046). MMRC dyspnea scale and BODE index were significantly higher in the frequent exacerbator group (1.8 vs. 1.1, p=0.016; 3.9 vs. 2.1, p=0.014, respectively). The fraction of CD146 cells significantly increased in the frequent exacerbator group (2.0 vs. 1.0, p<0.001). Conclusion: Frequent exacerbator had more severe airway obstruction and higher symptom score and BODE index. However, circulating endothelial cells measured by CD146 needed to be confirmed in the future.

Background: Chronic obstructive pulmonary disease (COPD) is one of the leading causes of disability and mortality worldwide. The aim of this study was to evaluate the risk factors associated with recurrent hospital admissions for exacerbation of COPD in Korea. Methods: A retrospective study of 77 consecutive patients hospitalized for exacerbation of COPD at Pusan National University Hospital during the time period January 2005 to May 2008 was performed. The information was collected from the hospitalization period: clinical information, spirometric measures, and laboratory variables. In addition, socioeconomic characteristics, co-morbidity, anxiety, and depression were reviewed. Frequent readmission was defined as 2 or more hospitalizations in the year following discharge. Results: During the 1-year period after discharge, 42 patients (54.6%) reported one hospital admission and 35 patients (45.4%) reported 2 or more hospital readmissions. Among the 35 frequent readmission patients, 4 had more than 10 readmissions. Univariate analysis showed that a body mass index (BMI) <$18.5kg/m^2$, duration >36 months, forced expiratory volume in 1 second ($FEV_1$) <50% predicted, arterial $CO_2$ partial pressure ($PaCO_2$) >40 mm Hg, and arterial oxygen saturation ($SaO_2$) <95% at discharge were associated significantly with frequent readmissions. The multivariate analysis revealed that BMI <$18.5kg/m^2$, $PaCO_2$ >40 mm Hg at discharge were independently associated with frequent readmissions for exacerbation of COPD. Conclusion: Frequent readmissions for exacerbation of COPD were associated with low BMI and hypercapnia at discharge.

General practitioners, internists, pediatricians, and family physicians are classified as so-called primary care physicians in the United States. We carried out this study for the purpose of answering the following question; "Who are the primary care physicians in Korea\ulcorner" We analyzed the 663, 154 claims which were drawn from the health insurance processing file made during the period of one month, April 1992 on the basis of systemic random sampling technique. The 663, 154 cases were matched with the doctor's file registered at the National Federation Medical Insurance by using the indivisual physician code number and analyzed according to the kind of specialty. If we follow the Geyman's definition of primary care physician in the United States, this study shows that they can take care of 43.2% of the total private clinic's claims in Korea. Provided that general practitioners and family physicians are considered the same way as in the United Kingdom, they could with only 8.3% of the total claims in Korea. The most frequent diseases are those which rank first to 46th in the total private clinic's claims. The proportion of the most frequent diseases was highest for pediatricians(90.4%) and followed by internists(81.4%), otolaryngologists(78.7%) and family physicians(76.5%). The proportion of the most frequent diseases in the most common 46 diseases was highest for radiologists(80.4%) and the next was as follows : general practitioners(78.3%), family physicians(67.4%), and internists(67.4%). We classified the most common 20 diseases of each specialty into 17 categories of ICD-9 and compared it with those of general practitioners. The specialists who had managed a similar disease pattern to those of general practitioners were identified as anesthesiologists, family physicians, general surgeons, and internists. Some specialists practicing at private clinics managed the diseases which were not quite appropriate for their specialties. After we evaluated each specialty by the most common diseases, the most frequent diseases, and the most frequent 20 diseases of each specialty in terms of the 17 categories of ICD-9, a tentative assumption is made that the primary physicians in the Republic of Korea are general practitioners, anesthesiologists, family physicians, internists, and general surgeons. This study has concluded that the categories of the primary care physicians are so diverse that their roles and distributions are distorted accordingly. Vigorous health policy efforts in correcting the malcomposition need to be made for the better provision of primary health care in Korea. in Korea.
