This research was designed to compare the health condition and the quality of life of the elderly inpatients with those of the normal elderly people. The subjects of study were 482 elderly inpatients and 304 normal elderly people. The research was conducted in July and August using the instrument WHOQOL. The results of the research are as follows: For the level of health, it was recognized that male was healthier than female, having higher the education, living in the city rather than in the rural, keeping the normal life than being in the hospital. There were little difference in the past medical histories of the elderly inpatients and the normal elderly people. As to the diseases currently under the treatment, there were some difference between the elderly inpatients and the normal elderly people but the tendency was similar in the kinds and the frequencies. As to the recognition for the quality of life between the elderly inpatients and the normal elderly people based on the records reflected on each of the domains of WHOQOL, the normal elderly people more positively recognized in the overall quality of life and the following domains: physical, psychological, level of independence, and spirituality/religion/personal beliefs. The normal elderly people more positively recognized especially in the level of independence domain (mobility, activities of daily living, dependence on medication or treatments, working capacity). In the social relationships domain only the sexual activity was significant and the normal elderly people more positively recognized. The elderly inpatients showed the correlation of over 0.5 in the overall quality of life and the following domains: environment, social relationships, physical, psychological, level of independence. It was over 0.6 in the physical domain and the domains of psychological and level of independence. and the psychological domains of level of independence and social relationships. For the points of overall quality of life, it had no correlation with hospitalization but the health condition, residential district, occupation, and taste exerted a significant effect. As a result of separate analyses of the elderly inpatients and the normal elderly people, the health condition and the age only were the common variable which would exercise a significant effect. Besides, the primary factors which would exercise the quality of life were the occupation and taste for the elderly inpatients, and the residential district and source of income for the normal elderly people. In conclusion, it is first and foremost important to improve the standard of health for the overall quality of life for the elderly people, regardless of hospitalization. Therefore, a plan must be urgently drawn up for revitalization of the health promoting projects for the elderly people and the public health projects for the elderly people, and the investment must be increased for settlement of health problems of the elderly people.

Objectives: Paraquat (PQ) is a widely used ionic pesticide that is fatal when ingested accidentally or for suicidal purposes. It is thought that chronic exposure of PQ is related with the development of Parkinson's disease, but epidemiological studies have not yet confirmed that theory. This study attempted to estimate the possibility of environmental PQ exposure through soil and water. Materials and Methods: We analyzed the amount of decomposed PQ solution in wet soil after exposure to ultraviolet light. An artificial rainfall condition was simulated over soil sprayed with PQ to measure the amount of eluted PQ. In addition, PQ was diluted in water from three differently rated rivers and the changes in PQ concentration were measured after ultraviolet exposure over one month. High performance liquid chromatography/ultra violet detection was used to analyze the concentrations of PQ. Results: In the method we used, the recovery rate of PQ showed a precision rate less than 5%, an accuracy greater than 88%, and the calibration equation was y=5538.8x-440.01($R^2$=0.9985). There were no significant differences in the concentrations of PQ obtained from the three specimens over a 1-week period. From the PQ-sprayed soil, the artificial rainfall conditions showed no PQ elution over a 1-month period, and there was no significant differences in PQ concentrations according to ultraviolet exposure among the three samples. Conclusions: PQ remains well adsorbed naturally in soil. However, it may still exist in an integrated state for a long time in the hydrosphere, so the possibility of PQ exposure through drinking water cannot be disqualified.

Objective: This study was to investigate the knowledge, health belief, and vaccination behavior on hepatitis A among university students. Methods: A self-administered questionnaire survey was conducted from $3^{rd}$ to $25^{th}$ March, 2014 and 197 subjects were enrolled in statistical analysis. Results: The result showed that the score for knowledge of the subjects on hepatitis A was $4.59{\pm}3.06$ out of 15 points, for health belief $2.39{\pm}0.28$ out of 4 points, and the vaccination rate of the subjects was 12.7%. There was significant difference in hepatitis A knowledge score according to experience of hepatitis A check-up and hepatitis A vaccination history of family members, and in health belief according to gender. For hepatitis A vaccination there was significant difference according to experience of hepatitis A check-up, family history of liver disease, hepatitis A vaccination history of family members, and education history of hepatitis A. As a result of logistic regression analysis experience of hepatitis check-up and hepatitis A vaccination history of family members were significant factors for hepatitis A vaccination. Conclusions: The level of knowledge, health belief for hepatitis A of the subjects was low and vaccination rate also low. The experience of hepatitis A check-up and hepatitis A vaccination history of family members were factors affecting hepatitis A vaccination. It would be necessary to develop programs for improving level of knowledge and health belief and raising the rate of hepatitis A vaccination for the university students in Korea.

Drug resistance of M. tuberculosis has been investigated with isolates from patients screened out of the sample population of the nationwide tuberculosis prevalence surveys or from the routine cultures. The results showed a close inverse relationship between prevalence of drug resistance and efficiency of the past or current treatment regimens of NTP. Individual drug resistance also showed a close relationship with the extent of use of the relevant drugs. Drug resistance was found in 38.0% of M. tuberculosis isolates from patients found in 1965 survey and remained unchanged until it increased upto 48.0% in 1980 survey. The resistance prevalence, however, dropped to 30.8% in 1985 and further to 25.3% in 1990 survey. Such decrease was fairly well coincided with a continuous increase of the treatment efficiency (from 60% in 1984 to 77% in 1989) in 1980s. Initial drug resistance also showed a similar trend, namely 26.2% in 1965, 23.9% in 1970, 20.1% in 1975, 30.6% in 1980, 17.4% in 1985, and 15.0% in 1990. The similar figures were observed in M. tuberculosis isolates from patients diagnosed in the routine services. Higher prevalence of initial drug resistance was observed among urban patients than rural patients and among young patients than old patients. These findings signify that a continuous survey on drug resistance permits to monitor efficiency of treatment programme of the country.

This study examines how single-person household expenditure patterns are different with respect to age and income groups using Tobit model. The expenditure data of the national household survey from 2006 to 2012 were used. The results show that income elasticities of all items are greater than 1 except for food & beverage, housing, water, electricity & gas, and Communication. Income elasticities are significantly different among consuming items. Additionally the income elasticities are also different between various age and income groups of single-person households. Therefore governments and businesses have to take this into account when devising their policies or strategies regarding single-person households. Especially, businesses need to adopt a strategy targeted at single-person households with high income and buying power such as unmarried professional people. As the number of single-person household increases the proportion of expenditures on necessities such as beverage, food, and energy is expected to decrease while that on services increases. Consequently policy responses are required to prepare for the expansion of service industries such as health, hospital, and housekeeping services.

Objectives : The Glycyrrhiza new varieties, WONGAM and SINWONGAM, were developed through interspecific cross between Glycyrrhiza glabra and Glycyrrhiza uralensis by the National Institute of Horticultural and Herbal Science, Rural Development Administration in Korea. This in vitro study was undertaken to compare the antioxidant and cytotoxic effects between Glycyrrhiza new varieties (WONGAM and SINWONGAM) and official compendia (Glycyrrhiza glabra and Glycyrrhiza uralensis). Methods : Antioxidant activity was determined by DPPH (1,1-diphenyl-2-picrylhy drazyl), ABTS (2,2-azino-bis (3-rthylbenz-thiazoline-6-sulfonic acid)) diammonium salt, Nitrite radical scavenging assay, and Reducing Power assay. Cytotoxicity was determined by MTT assay and cell morphology was observed by an inverted microscope. Results : The DPPH, ABTS, Nitrite radical scavenging activities and reducing power of Glycyrrhiza glabra, Glycyrrhiza uralensis, WONGAM, and SINWONGAM were evaluated at different concentrations (0, 10, 50, 100, 500, 1000 ㎍/㎖). Glycyrrhiza glabra, Glycyrrhiza uralensis, WONGAM, and SINWONGAM showed similar dose-dependent increase in antioxidant activities. The cytotoxic effects with increasing doses of Glycyrrhiza new varieties and official compendia did not differ in HCT116, HT29, A549, MDA-MB231, PC3, ACHN, and HeLa cells. However, significant difference in cytotoxicity were observed in AGS, MCF7 and Hep3B cells by Glycyrrhiza glabra, Glycyrrhiza uralensis, WONGAM, and SINWONGAM. Conclusions : These results showed that Glycyrrhiza new varieties and official compendia acts as a potent antioxidant. Also, the finding that equivalent cytotoxic potency was observed in a cell dependent manner. Our study suggests that Glycyrrhiza new varieties may offer a wide-variety of health benefits.

Along with the aging of the population, the number of dementia patients is increasing, and the social and economic burden is also increasing. Currently, the effective way to manage dementia patients is to identify patients with dementia early. However, in rural and island areas where medical staff are scarce, there is a problem that it is difficult to visit a hospital and get an early examination. Therefore, we propose a remote early detection system for dementia to solve the problems. The remote dementia early diagnosis system is a system that allows a patient to receive examination and treatment from a remote dementia expert using remote medical technology based on real-time image communication. The remote early diagnosis system for dementia consists of a local client system used by medical staff at health centers in the island, an image server that transmits, stores and manages images, and an expert client used by remote dementia experts. The local client subsystem satisfies the current medical law's remote collaboration by allowing the patient to use it with the health center's medical staff. In addition, expert clients are used by dementia experts, and can store/manage patient information, analyze patient history information, and predict the degree of dementia progression in the future.
