Abstract
OBJECTIVES
This study aimed to identify the effect of mental health on frequency of falls (single and recurrent falls) among elderly adults.
METHODS
Data were drawn from the 2015 Korean Community Health Survey. A chi-square test was conducted to compare differences in fall frequency according to health-related behaviors, chronic diseases, and mental health. Subsequently, multinomial logistic regression analysis was used to identify the effects of mental health on single and recurrent falls based on variables found to be significant in the chi-square test.
RESULTS
Recurrent falls were found to be more risky than single falls. Depression was significantly related to single falls (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.12 to 1.44). Depression (OR, 1.56; 95% CI, 1.38 to 1.76), sleep disorder (5 hours or less: OR, 1.12; 95% CI, 1.02 to 1.23; more than 9 hours: OR, 1.24; 95% CI, 1.07 to 1.44, respectively), and subjective stress (OR, 2.30; 95% CI, 1.90 to 2.78) were significantly related to recurrent falls.
CONCLUSIONS
The study’s findings suggest that specialized fall prevention programs are needed to address different types of falls in elderly adults. To prevent recurrent falls, systematic treatment strategies and rehabilitation training must improve physical function and mental health.

우리나라 노인에서 정신건강이 낙상에 미치는 영향을 확인하였고, 그 결과 단순낙상은 우울감 경험을 한 경우 낙상발생 위험이 증가했으며, 반복낙상은 우울감을 경험하고, 수면장애가 있으며(수면시간 6시간 미만, 9시간 이상), 주관적 스트레스가 커질수록 낙상 위험이 증가하였다. 최종적으로 노인의 정신건강이 반복낙상에 미치는 영향이 더 큰 것을 확인하였다. 본 연구결과를 통해 낙상 예방 및 관리를 위한 보건사업을 제시하고, 반복낙상자의 정신적/신체적 기능 증진을 위한 치료전략과 재활훈련 계획의 근거자료로 활용할 수 있을 것으로 생각된다.

Abstract
OBJECTIVES
The purpose of this study was to establish a basis for improving or strengthening the preventive strategy against scrub typhus in Korea by comparing and analyzing the difference of prevention behaviors contributing to the occurrence of scrub typhus in Japan and Korea.
METHODS
The survey was carried out in Jeollabuk-do, which is a high risk and high incidence area, and Fukuoka Prefecture, which is a high risk and low incidence area. The study included 406 Korean farmers and 216 Japanese farmers. Data were collected through face-to-face surveys by interviewers who had completed standardized education.
RESULTS
Korean farmers have a higher percentage of agricultural working posture that involved contact with weeds than Japanese farmers (p<0.05). The frequency and proportion of weeding were lower in Korean farmers than in Japanese farmers (p<0.05). The level of knowledge about scrub typhus was significantly higher among Korean farmers than among Japanese farmers (p<0.05). Mostly, the behavior of agriculture work was more appropriate for Japanese farmers than for Korean farmers (p<0.05). The total average level of agricultural work was lower in Korea than in Japan, lower in men than women, and lower in part-time farmers than full-time farmers (p<0.05).
CONCLUSIONS
This study suggests that it is reasonable to develop and provide a program that can improve the level of preventive behavior taking into consideration the characteristics of the subject in order to reduce the incidence of diseases in high-risk areas for scrub typhus.

Abstract
PURPOSE
The aim of this study was to investigate the association between the metabolic syndrome and alanine aminotransferase(SGPT) levels in Korean adults.
METHODS
The study subjects were 4,325 adults aged > or = 19 years without an apparent cause of liver disease from the Third Korea National Health and Nutrition Examination Survey(2005). The metabolic syndrome was defined using criteria established by the NCEP/ATP III, while abdominal obesity was assessed based on the Asia-Pacific guidelines. Subjects with SGPT > or = 40 IU/L were considered to have elevated SGPT levels. Demographic characteristics, waist circumference, blood pressure, triglyceride, HDL cholesterol, fasting blood sugar were recorded for statistical analysis.
RESULTS
The prevalence of elevated SGPT levels was significantly increase with the presence of the metabolic syndrome and its components. In multiple logistic regression analyses, odds ratio for the elevated SGPT levels was significantly high in the subjects with the metabolic syndrome compared to the subjects without metabolic syndrome after adjusted for socio-demographic characteristics and health-related behavior.
CONCLUSIONS
The metabolic syndrome was independently associated with SGPT levels in Korean adults.

Abstract
PURPOSE
There has been an epidemic of measles in Korea since 2000. Therefore, we analyze the epidemiologic haracteristics of measles in Gwangju Metropolitan City.
METHODS
We reviewed the epidemiologic investigation records and laboratory data of the measles patients reported in Gwangju Metropolitan City from January 1st 2000.
RESULTS
1) Demographic characteristics: Totally, 3,392 cases were surveyed and 3,300 cases were enrolled (3,300/3,392, 97.3%). Fifty-four percents of the patients were male (1,771/3,300) and forty-six percents of the patients were female (1,529/3,300). Average age of the patients was 8.20 years (8.20 5.56 years). Forty-seven percents of the patients were reported in the interval from November 2000 to December 2000 (1,582/3,298, 47.9%). 2) Clinical manifestations of the patients: Common symptoms of measles patients were fever (3,300/3,300, 100.0%), skin rash (3,068/3,300, 93.0%), cough (2,889/3,300, 87.5%), rhinorrhea (1,883/3,300, 57.1%), headache (1,445/3,300, 43.8%), conjunctival injection (1,182/3,300, 35.8%), and oral thrush (832/3,300, 25.2%). Among the patients, 250 patients had complications (250/3,300, 7.6%) and most of them were respiratory complications (220/250, 88.0%). 3) Vaccination: Eighty-six percent of the enrolled patients answered the question about vaccination (2,854/3,300, 86.4%); 808 patients were not taken a shot (808/2854, 28.3%), 1,762 patients received one dose (1,762/2,854, 61.7%), and 284 patients received additional dose (284/2,854, 9.9%). 4) Laboratory data: Laboratory confirmed cases were 780 patients (780/3,300, 23.6%); 603 cases were confirmed serologically, 185 cases were positive in PCR, and virus was isolated in 6 cases. Genetic sequencing of the isolated viruses was clade H1 and closely related to that of China.
CONCLUSION
Therefore, adequate surveillance and maintenance of high coverage rate of the vaccination would be the crucial factors to eradicate measles

Abstract
PURPOSE
S: This study was to investigate the source of infection, mode of transmission and incidence of a measles outbreak among infants living in a Gwangju welfare institution in July 2000.
METHODS
The information about 63 children was collected through the nurses interview and blood sampling and laryngopharyngeal swab were conducted to the children. In addition, an epidemiologic survey was performed to confirm the infection dissemination route.
RESULTS
Before the outbreak, two children living at the institution were admitted to a university hospital for other health problems. These children shared a room with a 5 year old diagnosed with meningitis who was later diagnosed as having measles after rashes appeared. The two children developed measles after returning to their institution and the infection spread to other children in the institution. Among 63 children observed, 14 children(22.2%) developed measles, secondary attack rate of measles due to index cases was 19.7%. And 78.6% of the patients were between 4 and 8 months old. The room where the index case lived showed an attack rate of 81.8%, which is a much higher rate compared to other rooms. The attack rate among boys(26.0%) was higher than that of girls(12.5%), but it was not statistically significant.
CONCLUSIONS
This outbreak was considered to be a nosocomial infection, where the index cases were admitted to a hospital, infected and the infection spread to children. Further studies are necessary to find out the maternal antibody levels of infants of post-vaccinated mothers and the optimal age for measles vaccination.

Abstract
Coronary artery disease(CAD), such as atherosclerosis, myocardial infarction and sudden death has been considered the major cause of death for decades and their incidence and prevalence are still increasing. Numerous studies have been done on the risk factor analysis of CAD. But, they were usually based on the clinical and epidemiologic studies of the living patients. The purpose of this study was to evaluate the risk factors for the cardiovascular diseases in autopsy cases from Korean men. The author analysed 81 cases of heart who underwent legal autopsy from Aug. to Dec. 1998. The author measured percent stenosis of coronary artery, site of stenosis, perimeter of aorta, heart weight, body weight, and height and checked the past history including smoking, drinking and age. The results were as follows: 1) Coronary artery stenosis had a positive correlation with age, perimeter of aorta and smoking, but had no correlation with body weight, height, body mass index, heart weight, and drinking. 2) According to the logistic regression analysis, smoking amount and age were significantly associated with coronary artery stenosis. In conclusion, smoking was the most significant independent variable for coronary artery stenosis of some Korean men.
