Objectives : This study tried to explore the prevalence of chronic physical diseases in patients with schizophrenia and its effects on total medical costs. Methods : The Health Insurance Review and Assessment Service data in 2014-2015 was employed. Only the injuries and diseases, identically diagnosed 3 times or more as a major or minor injury and disease, were classified into chronic physical diseases to improve data accuracy. Total medical costs included out-of-pocket and insurer's costs from health care system perspective. Results : It was shown that 24.5%, 17.3% and 23.4% of schizophrenia patients had one, two and three or more chronic physical diseases, respectively. There was a high prevalence of not only metabolic, but also musculoskeletal, diseases in those patients. The amount of 2015 total medical costs of patients with schizophrenia in 2014 was about 1.08 trillion won. The factors affecting the costs included sex, age, number of chronic physical diseases, and health insurance status. Conclusions : It is considered that clinical practice guidelines based on personal diseases may not sufficiently solve the problems for comorbidities in schizophrenia patients. Accordingly, it should be required to develop models for new types of medical systems capable of treating and caring varied illnesses at the same time.

환절기나 겨울철에 사람들은 독감, 천식, 비염 등 호흡기성 질환의 발병율이 높아지는 것과 동일하게 닭에서도 호흡기성 질병이 발생된다. 더군다나 닭은 어느 동물보다 호흡기를 구성하고 있는 실질장기들의 표면적이 넓어 그 만큼 많은 병원체에 쉽게 감염되며, 이에 따라 양계농장에서는 이들 전염병으로 피해가 속출하고 있다. 밤낮 기온차가 큰 환절기나 추운 겨울철에는 계사내 보온과 에너지절약, 이 두 가지 효과를 동시에 얻기 위해 노력하다 보면 신선한 산소의 제공

This study was carried out to evaluate the inhibition of growth and collagenase activity of Salvia miltiorrhiza Bunge against microorganisms causing periodontal diseases. The ethanol extract of Salvia miltiorrhiza showed sig-nificant growth inhibition against microorganisms causing periodontal diseases. Ethanol extract was further fractionated with organic solvents in the order of hexane, chloroform and ethyl acetate. Among the fractions tested, the hexane fraction showed the highest cell growth inhibition. The minimal inhibitory concentration (MIC) of the extract against C. curvus, C. rectus, E. corrodens, F nucleatum, P. gingivalis, P. intermedia and W. succinogenes were 200, 50, 50, 250, 150, 250 and 200 ${\mu}g$/ml, respectively. The inhibition of collagenase activity by organic solvent fractions were higher than that of minocycline, and the inhibition ratio of collagenase activity was $88.2{\pm}2.1$ % in the chloroform fraction.

This study aims to understand health care consumer's information searching behavior according to their presence of chronic diseases. For this purpose, 240 patients' data of university hospital located in Seoul were collected by surveys from 9 February to 11 February 2016. For statistical analysis, we used SPSS Ver. 26.0. The main results of this study are as follows: First, Chi-square test showed that chronic patients used expert information sources and experiential information sources more than those without chronic diseases. Second, chronic patients were found to search nutrition management, exercise management, and patient case. Lastly, in the case of hospital-related searches, patients with chronic diseases searched more waiting time and medical expenses than those without chronic diseases. The significance of this study is to provide basic data for efficient information provision and establishment of marketing strategies reflecting information needs of health care consumers.

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.

최근 들어 환경 오염과 식습관의 변화로 인해 알레르기성 질환이 널리 유발되고 있다. 특히 평생 건강의 시초라 할 수 있는 소아 시기에 알레르기로 인한 천식, 비염 및 아토피 등의 증세는 소아 뿐만 아니라 부모까지도 위험 요소로 크게 자리잡고 있는 실정이다. 따라서 본 논문은 소아기에 가장 흔하게 발생되는 질환인 소아 천식을 예방하려는 목적으로 연구를 행하였다. 의사 표현 능력이 부족한 소아에게서 울음소리는 소아의 유일한 자기 표현 방법이다. 본 논문에서는 천식을 앓고 있는 소아의 울음소리를 분석하였으며 정상 소아의 울음소리를 동일한 환경 설정으로 분석하여 이를 비교, 분석하여 천식 질환 소아와 정상 소아간의 상관성을 입증하고자 한다.

It is crucial that the WRMSD is realized as a critical job-related diseases for the construction workers. It is caused by the characteristics of repetitive work, uncomfortable work methods and continuous unsuitable physical posture. The objective of this research is to evaluate the workload for the carpenters and structural steel workers. Investigation on the posture and behavior for the workers as well as personal sensitivity to the workload is conducted. The laboratory tests with graduate students are conducted to estimate inconvenience in terms of personal sensitivity to the workload. The results of this research will be used to perform the further researches on ergonomic and technological approaches to improvements of the hand-intensive tasks in the construction industry.

We have previously isolated seven strains of spiral form bacteria, which have shown several similar characteristics to Leptospira from patient with epidemic pulmonary hemorrhagic fever and matural paddy water. Further studies have performed to characterize them. All of the isolated bacteria were aerobic, gram negative and spiral form and their growth were completely inhibited at temperature below $13^{\circ}C\;and\;50^{\circ}C$. In sensitivity test to drugs, the bacteria were resistant to the bile salts, 5-Fu and Amphotericine B, but sensitive to the 8-Azaguanine. The isolated bacteria as well as 5 serotypes of Leptospira interrogans reacted the patient sera and it was also shown that antisera from rabbit immunized with the isolated bacteria reacted with 5 serotypes of Leptospira interrogans. These results suggest that the isolated bacteria may belong to the genus Leptospira.

Purpose : It is known that 3-50 percent of type 1 diabetes mellitus(T1DM) patients develop autoimmune thyroid disease. We analyzed the clinical characteristics of autoimmune thyroid disease(AITD) developed in patients with T1DM in Korean. Methods : The medical records of 139 patients, who were followed up in Department of Pediatrics, Seoul National University Children's Hospital from Jan. 1981 to Jul. 2004, were analyzed retrospectively. Results : Forty-four males and 95 females were enrolled. At least one of the autoantibodies for thyroid was positive in 54 cases. The detection rate for AITD was not correlated with sex ratio, control of T1DM, body mass index, age at diagnosis of T1DM, and familial history of thyroid disease, between two groups. In the male group, AITD was more frequently found at a younger age than in the female group. The frequency of AITD was significantly higher in the goiter group without sex differences. In the thyroid disease group, 40 patients(74.0 percent) were euthyroid, seven patients(12.9 percent) were hypothyroid, and seven patients(12.9 percent) were hyperthyroid. Conclusion : We should monitor thyroid function and autoantibodies routinely in T1DM patients who develop goiters, or young boys with T1DM.
