Pathological study was performed on the 135 cases (137 lesion) of early gastric cancer (EGC) diagnosed during the period from 1970 to 1988. The gastrectomy specimens were obtained from Pusan National University Hospital and Pusan Paik Hospital. The statistical analysis was applied on the point of pathological and epidemiological aspects. The results obtained were summarized as follows: 1) The proportion of patients with EGC of all gastric cancer diagnosed in Pusan area during the period of 1970 to 1974 was 1.3%, those during 1975 to 1979 was 1.7%, those during 1980 to 1984 was 7.8%, and those during 1985 to 1988 was 20.0% respectively. 2) The model age group was 6th decade in both sexes. The average age of patients with EGC was 50. 1-year-old in men and 47. 9-year-old in women respectively. The sex ratio (M/F) was 2 : 1 but it was lower for young people than for old people. 3) The proportion of sites involved by the EGC in the stomach was as follows : the antrum 61%, the body 39%, and the cardia and fundus 0.01%. The intestinal type cancer more frequently involved the lower portion than the upper portion of the stomach. 4) Regarding the distribution of the gross types of EGC, the elevated group (Type I, IIa) accounted for 14%, the flat type (Type IIb) accounted for 4%, and the depressed group (Type IIc, III) accounted for 82%. There was no correlation between the gross type and the depth of the lesion. The elevated group was more frequent in intestinal type than in diffuse type. 5) The size distribution of the EGC was as follows : 46% of the lesions were smaller than 2.0 cm in diameter, 47% were between 2.1 to 5.0 cm, and 7% were larger than 5.1 cm. There was no correlation between the size of the lesion and the gross type. 6) The intestinal type of EGC was 77 lesions (56.2%) and the diffuse type 60 lesions (43.8%). The ratio of both types (I/D) was 1.3 : 1, and it was lower for younger people than for old people. 7) Ten of 135 cases (7%) had lymph node metastases. The metastatic rate of EGC confined to submucosa was much higher than that of EGC confined to mucosa only, but the metastatic rate was not related with the size of the lesion.

PURPOSE: This study was undertaken to investigate the traumatic brain injury(TBI) in childhood and to identify factors related with its prognosis. METHODS: The medical records of 256 children with traumatic brain injury were analyzed retrospectively, who were treated in Chungnam National University Hospital for more than 6 years from January, 1998 to December, 2003. Outcomes were classified by age, sex, cause, Glasgow Coma Scale(GCS), Glasgow Outcome Scale(GOS), sequelae and so forth. RESULTS: A total of 256 patients were identified. The male to female ratio was 1.9:1. The main cause of TBI was traffic accidents(67.1%), followed by falls(25.8%). The outcomes of TBI were determined by GOS, in which death occurred in 16 cases(6.2%), severe disabilities in 11 cases(4.3%), moderate disabilities in 24 cases(9.4%), and good recoveries in 205 cases(80.1%). Poor prognostic factors were low GCS, post-traumatic early seizure, high blood glucose levels and abnormal pupil reflexes(P<0.05). The sequelae of TBI were quadriparesis(3.5%), learning disability(3%), mental retardation(2.3%), hemiparesis(1.6%) and others. CONCLUSION: This study suggest that it is possible to predict poor outcomes of TBI children by assessing the clinical manifestations. A long term follow-up of seizures and other sequelae is essential to TBI children who have poor prognosis.

OBJECTIVE: The purpose of this study was to analyze current status of the web sites dealing with asthma in the Internet, and to evaluate their technical aspects and contents. METHODS: The evaluation tool consisted of four areas(construction, operation, accessibility, and content) with twenty-six items. Four sites including the contents related with symptoms of asthma, consultation of health professionals, and treatment and nursing for asthma were selected to be analyzed. RESULTS: The results of the analysis were as follows: 1) there was no web site dealing with asthma managed by public institutions 2) the only 5% of the top 100 sites were found to be related with the asthma by exploring the top five search engines in Korea and 3) the evaluation scores four web sites were 6-11 out of 18 in the category of construction, 10-21 out of 24 in operation, 5-10 out of 15 in accessibility, and 8-18 out of 21 in content. CONCLUSION: In conclusion, it will be possible to prevent asthma at first through web sites, which will be one of the most beneficial aspects of web site, so the system to evaluate web sites should be developed to provide high-quality information about asthma.

BACKGROUND: Clonidine, which is known to have analgesic and sedative properties, has recently been shown to be an effective preanesthetic medication in humans. The drug may cause side effects, including bradycardia and hypotension. This study was conducted to evaluate the ability of intravenous atropine to increase the heart rate (HR) in awake adults receiving clonidine preanesthetic medication. METHODS: We studied HR responses to intravenous atropine in 45 patients assigned randomly to either a control group, who received no medication (group 1, n=15), or clonidine groups, who received oral clonidine of 2~2.5 mcg/kg (group 2, n=15), or 4.5~5 mcg/kg (group 3, n=15) 90 min before scheduled induction of anesthesia. When HR and blood pressure had been confirmed to be stable in operating room, all patients received incremental doses of atropine, 2.5, 2.5 and 5 mcg/kg at 2-min intervals. The HR and mean arterial pressure were recorded at 1-min intervals. RESULTS: Before atropine injection, the HR decreased significantly (P<0.05) in group 3. The increases in HR in response to a cumulative dose of atropine 10 mcg/kg were 21+/-8, 17+/-7 and 7+/-5 beats/min (mean+/-SD) in group 1, 2 and 3, respectively (P<0.05). The positive chronotropic response to intravenous atropine was attenuated significantly only in group 3 (P<0.01). CONCLUSIONS: It was concluded that oral clonidine of 4.5~5 mcg/kg decreased HR significantly, and blunted the increase in HR after intravenous atropine in awake adults although oral clonidine of 2~2.5 mcg/kg did not.

OBJECTIVE: The purpose of this study was to develop the decision tree models to classify the characteristics of those who had not undergone the health screening tests provided by the National Health Insurance Corporation. METHODS: Total of 5,102,761 subjects of health screening services in the year of 2002 was used. The data was divided into two data-sets (disease VS. non-disease group). The target variable was whether they took the health screening services. The number of input variables was 25 in total. RESULTS: The decision trees were classified into fourteen different types of non-examinees in the non-disease group and nineteen in the disease group. The ROC curve areas in the non-disease and disease groups were .761 and .714, respectively. CONCLUSION: The different types of non-examinees classified by the decision tree models would facilitate the foundation for the further analysis of individual characteristics and the effective health screening service management in future.

Background: The purpose of this study was to extract the major areas of interest in health insurance research in Korea, and infer policy agendas related to health insurance by analyzing research keywords. Methods: For this study, 2,590 articles were selected from among 7,459 academic papers related to health insurance published between January 1987 and December 2018, which were looked up using the Research Information Sharing Service (RISS). Keyword extraction and keyword network analysis were performed using the KrKwic, KrTitle, and UCINET software. Results: First, the number of studies in the area of health insurance continued to increase in all government terms, and it was not until after the 2000s that the subjects of health insurance researches were diversified. Second, degree centrality showed that ‘medical expenditure’ and ‘medical utilization’ were consistently high–ranking keywords regardless of the government in power. Aging and long-term care insurance-related keywords were ranked higher in the Lee Myung-bak government, Park Geun-hye government, and Moon Jae-in government. Third, betweenness centrality showed the same high ranking in key topics such as medical expenditure and medical utilization, while the ranking of key keywords differed depending on the interests and characteristics of each government policy. Conclusion We confirm that health insurance as a research topic has been the main theme in Korean health care research fields. Research keywords extracted from articles also corresponded to the main health policies promoted during each government period. Efforts to systematically investigate policy megatrends are needed to plan adaptive future policies.

Background: Among the issues caused by the increase of one-person households the health problems and primary medical needs of one-person elderly households among the issues with the increase in one-person households is very important. The purpose of this study was to identified health care needs and problems of one-person elderly households by comparing health behavior, health status, disease prevalence rate, and medical needs to one-person elderly households and multi-person households. Methods: Data were obtained from the 2017 Community Health Survey. In this study, 66,211 people who were over 60 years of age without missing variables were included in the final analysis. Results: One-person households showed poorer overall health behaviors, such as nutritional behaviors, exercise behaviors, drinking and smoking behaviors, and poorer subjective and objective health status than multi-person households. Furthermore, albeit the high requirement of medical services for mental health outcomes such as suicide attempts, the rate of not receiving services was also high indicating high barriers to receive and access health care. Conclusion Comprehensive and direct comparison of health and medical factors revealed the medical vulnerability and unmet needs in terms of health promotion in the single-person elderly households. These results can be applied as the basic information to understand the needs and medical problems of these risk groups by primary medical doctors who predominantly treat single-person elderly households and can also be used as basic data for policy development in order to solve these unmet medical care needs.
