Objectives: This study was performed to investigate the management status of chronic disease at community health centers. Methods: The study subjects were 450 employed persons at community health centers in Jeonlanamdo. General characteristics, status of chronic disease management and health education were collected for statistical analysis. The differences on management status among working areas were assessed with chi-square test and ANOVA. Results: The mean values of work duration were 18.7 years in rural, 14.4 years in fishing village, and 17.4 years in urban-rural, respectively. The number of management registration was highest in hypertension. The ways of disease management were medication check-up, diet stopping smoking. The contents of group health education were exercise, diet and prohibition of smoking. The place of health education was town assembling hall. The fields which officials wanted to be educated were symptom, diagnosis, treatment and complication. The most important field was early detection of chronic disease patients and health education. Finally, the field requiring support was work standardization. Conclusions: Community health workers have worked positively in chronic disease management. The barriers to work were the lack of professional and preliminary data. The support system with other health organ and health education were needed for the improvement of working ability.

Purpose : The accuracy of bacteriologic diagnosis of beta-hemolytic streptococcal pharyngotonsillitis depends on the degree of carrier rate in that area where the throat swabs are obtained and the evaluation of serological T typing as an epidemiologic marker is important to understand epidemiology of streptococcal infection. The purpose of this study is to know the carrier rates of group A streptococcus in normal children form four different areas and to find out the epidemiologic characteristic in distribution of the serotypes for 3 years. Method : Throat swabs were obtained from the tonsillar fossa of normal school children in four different areas(Uljin, Seoul, Osan, Kunsan) from March to May 1996, in Uljin in April 1997, and in Uljin in April 1998. The samples were plated on a 5% sheep blood agar plate and incubated overnight at $37^{\circ}C$ before examination for the presence of beta-hemolytic colonies. All isolated beta-hemolytic streptococcus were grouped and serotyped by T agglutination. Results : The carrier rate of beta-hemolytic streptococci and group A streptococci in 1996 were 27.6%, 18.6% at Uljin; 16.4%, 2.7% at Seoul; 33.0%, 26.0% at Osan; 20.0%, 12.3% at Kunsan, respectively. Among 1,192 normal school children from 4 different areas, we obtained 179 strains of group A streptococci. Fifty two percent of the strains were typable by T agglutination in 1996. Common T-type in 1996 were NT, T1, T3, T2 at Uljin; T12, T25 at Seoul; NT, T6, T28 at Osan; T25, T4, NT, T5 at Kunsan, in decreasing order, respectively. At Uljin, T1, T3, T25 accounted for 69% of strains in 1996, T1, T12, T25 accounted for 70% in 1997, and T12, T4 accounted for 88% in 1998. Conclusion : Higher carrier rates were found in Uljin and Osan, where there are a lower population density with scanty of medical facilities compared with another areas. We supposed that low carrier rates is likely to be related to antibiotic abuse or some epidemiologic factor. The periodic and seasonal serotyping analysis is important in monitoring and understanding the epidemiologic patterns of group A streptococci.

The antioxidant activities of volatile aroma extracts from Cudrania tricuspidata (Carr.) Bureau were examined using two antioxidant assays. Ten volatile aroma compounds identified in this plant were also tested for antioxidant activity. The volatile aroma extracts of stem and root from C. tricuspidata exhibited antioxidant activities with a clear dose response relationship in both aldehyde/carboxylic acid and lipid/malonaldehyde assays. Antioxidant activities of volatile aroma extracts from C. tricuspidata at $500{\mu}g/mL$ were $77.02{\pm}8.12%$ (stem) and $74.19{\pm}6.82%$ (root) in the aldehyde/carboxylic acid assay. Antioxidant activities of volatile aroma extracts from C. tricuspidata at $160{\mu}g/mL$ were $76.17{\pm}4.25%$ (stem) and $61.43{\pm}2.11%$ (root) in the lipid/malonaldehyde assay. Positively identified volatile aroma components in extracts of stem and root from C. tricuspidata were seven terpenes and terpenoides, 14 alkyl compounds, 11 nitrogen containing heterocyclic compounds, three oxygen containing heterocyclic compounds, 12 aromatic compounds, nine lactones, and seven miscellaneous compounds (possible contaminants). Among the positively identified compounds, eugenol, isoeugenol, and 2,4-bis (1,1-dimethylethyl)phenol exhibited antioxidant activities comparable to those of BHT and ${\alpha}$-tocopherol. Vanillin and 2-acetylpyrrole showed moderate activities in the lipid/malonaldehyde assay. These results suggest that consumption of antioxidant-rich beverages prepared from C. tricuspidata could have beneficial effects on human health by preventing diseases caused by oxidative damage.

In order to estimate the utilization pattern of a rural health subcenter, and to identify the recognition for it among the farmhouse members in a suburban area, a questionnaire survey was carried out for objects of 696 population. The results observed were as follows: The annual utilization rate of rural health subcenter for a basic health service unit was 25.0 per 100 persons, and annual mean visiting times was 0.22 times. And the most frequent disease by annual health subcenter utilization illness was musculoskeletal disease(30.6%), and the next was respiratory disease(14.1%), gastrointestinal disease(13.9%) by order. Favorite reason for community health subcenter utilization were near distance from living place(49.6%), lower disease severity(18.9%) and lower medical cost(18.1%) by order. But disfavoring reasons for it were absence of specialist(20.2%), non effective treatment(19.2%) and insufficient equipment(14.7%) by order. And insufficient items about community health subcenter utilization were restriction of treatment limit(40.7%), lower reliance(22.5%) and difficulty in traffic(13.4%) by order. The results of logistic regression analysis suggested that statistically significant factors in health subcenter utilization was educational level. The desirable works for the health subcenter in a suburban area were disease control of elderly and disease preventing service. These results suggested that to increase the utilization of rural health subcenter in a suburban area and to promote the accessibility of rural residents to primary health care, there must be considered public relation about health subcenter, improvement of medical quality and change of priority about health subcenter's works.

The purpose of this study was to investigate the antioxidative and antiallergic effects of persimmon leaf extract. Antioxidative and anti-inflammatory effects of the crude persimmon leaf extract (PLE) and the partially purified persimmon leaf extract (PPLE) were determined in in vitro assays by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and superoxide anion radicals, and 5-lipoxygenase (5-LO) and cyclooxygenase (COX). Total phenols and total flavonoid levels of PLE and PPLE were $230.0{\pm}19.6$ mg/g and $475.5{\pm}38.7$ mg/g, and $34.8{\pm}6.5$ mg/g and $78.8{\pm}3.6$ mg/g, respectively. DPPH and superoxide radical-scavenging activities ($SC_{50}$) of the PLE and PPLE were $23.8{\pm}3.2$ ppm and $10.0{\pm}1.3$ ppm, and $47.6{\pm}3.4$ ppm and $22.4{\pm}3.3$ ppm, respectively. Inhibitory activities ($IC_{50}$) of PLE and PPLE against 5-LO, COX-1 and COX-2 were $77.1{\pm}11.7$, $38.6{\pm}7.0$ ppm, $47.4{\pm}7.7$, $25.3{\pm}6.3$ ppm, and $129.5{\pm}5.5$, $84.5{\pm}2.3$ ppm, respectively. Moreover, two extracts inhibited dose-dependently NO production in LPS-stimulated RAW 264.7 cells, and also effectively inhibited the cutaneous anaphylaxis reaction activated by anti-dinitrophenyl IgE antibody in mice. These results suggest that PLE and PPLE may be useful for phytochemical materials for prevention and treatment of radical-mediated pathological and allergy diseases.

Coronary artery disease has increased in Korea as the country enters the aged society. It is well known that the incidence of coronary artery disease is related to aging, hypertension, diabetes, hyperlipidemia, and dietary habit. For effective treatment of significant coronary stenosis, close coordination between cardiac surgery and cardiology team is essential. Especially cardiologists' decision whether to do the stent placement or CABG is very important because the cardiologists usually start to consult the patients for their treatment. Recently, non-surgical interventions(that is stent placement) in cardiology field have dramatically increased as the national insurance system removed the limitation of the number of stents deployed. However, accidents are often caused by inappropriate use of stents, especially in patients with triple coronary disease or left main disease with heavy coronary calcifications. Another aspect of stent placement is to cope with an emergency case in the event of coronary rupture or pericardial tamponade during coronary interventions without cardiac surgeons. In the past two years, the Korea Consumer Agency (Consumer Dispute Coordination Committee) analyzed eight cases of medical dispute settlement. Only two hospitals were manned with both cardiologists and cardiac surgeons. Seven patients died of procedures of stenting and five patients died on the day of the procedure. Among the 8 cases, 5 cases showed 3 vessel disease and the rest of the cases had either severe calcification, complete occlusion or poor coronary antomies for stenting According to a 2017 national data registry of coronary stenting, less than 3 drug-eluting stents were implanted in 98% of all patients. In 2015, the number of stent procedures was 38,922, and approximately in 800 (2%) cases, more than four stents were used per patient. We emphasize that it is necessary to seriously consider the cost-benefit analysis between stent and CABG. The patient has the right to choose the right procedure by asking the liability of 'instruction explanation obligation'. He should be well informed of the pros and cons of both procedures to avoid overuse of stent. It can be solved by intimate discussion of individual cases with the cardiac surgeon and the patient. Unilateral dialogue with the patient, forceful restriction on the number of stenting, lack of surgeon's backup in difficult cases should all be avoided. It is also necessary to solve the problem not only at the hospital level, such as multidisciplinary integrated medical care, but also a nationwide solution such as expanding cardiac surgeons as essential personnel to public officials.

This study was conducted to assess the morbidity and medical facilities utilization patterns of the residents in urban low income area. Study population included 2,002 family members of 468 households in the low income area (LA) of Nam-san 4 Dong, Jung Gu of Taegu city and 1,709 family members of 374 households in surrounding neighbourhood control area (CA). Well trained nursing school students interviewed mainly with housewives according to the pretested questionaire between July 1 and July 30, 1984. Age-sex distribution of the study population in LA was similar to that in CA. The average monthly income of a household in LA was 236,000 won and 356,000 won in CA. Educational level of the residents in LA was lower than that in CA; average years of school education of the 20 years old or above in LA was 6.9 years compared with 8.5 years in CA. The average family members per room in LA was 2.6 and 2.2 in CA, and proportion of Medicaid program beneficiary was 29.4% in LA and 1.9% in CA. Prevalence rate of illness during 15-day period was 131 per 1,000 population in LA and 71 in CA(p<0.01) and that of the chronic illness for 1 year was 134 per 1,000 population in LA and 89 in CA(p<0.01). The most common illness experienced during 15 days was respiratory disease(24.0% in LA ana 29.8% in CA) and followed by gastro-intestinal disorders(21.0% in LA, 20.6% in CA). Injury or poisoning was 10.3% in LA and 3.3% in CA. Castro-intestinal disorder was the most common chronic illness in both LA (22.7%) and CA (21.7%), and followed by musculoskeletal disease in LA and neuralgia in CA. Mean activity restricted days among the persons with illness during 15-day period was 4.0 days in LA and 2.2 days in CA. Among persons with illness during 15 days, 17.9% in LA and 11.6% in CA did not seek any medical treatment and the most frequently utilized medical facility was pharmacy in LA (35.5%) and local clinic or hospital OPD in CA (42.1%). Among persons with chronic illness, 15.2% in LA and 9.2% in CA did not seek for medical treatment, and residents in LA as well as residents in CA utilized local clinic or hospital OPD more frequently than pharmacy or drugstores, especially those who have medical insurance. The most common reason for not treating illness experienced during 15-day period and chronic illness was economical constraint in both LA and CA. The higher prevalence rate of illness during 15-day period and chronic illness in LA than that in CA seems to be highly correlated with their lower economic status and educational level and crowded living condition. The utilization pattern of medical facilities was associated with the medical security status. A program to improve the economic status and living condition should be integrated with the health program to promote the health of the population in low income area.

To investigate determinants of health care utilization of the physically disabled over 20 years old in age living in Taegu city, a self-administered questionnaire survey was carried out for 337 disabled persons with chronic illness from April to July, 1997. Health care utilization .ate was 81.9%(69.1% for hospital or clinic and 12.8% for pharmacy). Marital status, job, health concern, and response to illness showed statistically significant relationship with health care utilization(p<0.05). By path analysis, job, economic status, medical security type and response to illness had a significant direct effect on health care utilization(p<0.05), however, health concern and regular source of care had an indirect effect. The reasons of no health utilization were due to economic problem(31.1%), no symptom(18.0%), inconvenience to seek care or no accompanying persons to be helped(14.8%), unseriousness of the severity of the illness(14.8%), too busy to be treated or no free time(8.2%), hopeless prognosis to be treated(6.6%) in order. In conclusion, it is recommended that the program for expanding medicaid, improving socioeconomic status by getting a job and health education to increase the health concern toward physically disabled should be implemented to increase health care utilization rate.

This study aimed to develop a new type of functional citrus beverage (Citurs-F) containing flavonoids extracted from the young fruits of satsuma mandarin ($Citrus$ $unshiu$) and matured fruits of Jeju native dangyooja ($C.$ $grandis$). We made beverages that contained 30% of satsuma mandarin extract with different percentages of concentrated dangyooja-derived flavonoid extracts. In sensory evalution, the highest response indices of color, taste and aroma were from the beverages based on the 30% young fruit extracts plus 15% (Citrus-F-15) and 20% (Citrus-F-20) flavonoids extract from the dangyooja using the KILO prep. In the changes of body weight after oral administration of the Citrus-F, the rat group with HF diet plus the Citrus-F decreased the body weight compared to the rat group fed only HF diet. This effect was to be continued for 9 weeks until the end of experiment. In the lipid content in blood, the rat group with oral administration of citrus extractions merely tended to resolve it in serum test. However, all the 0.1% Citrus-F-15 and Citrus-F-20 treated rat groups from the beginning or after 5 weeks appeared the lowest lipid contents in the blood. In the cholesterol contents, the rat group feeding the KILO-prep's extraction from the beginning weren't significantly recognized them in the group but the rat group feeding 0.1% Citrus-F-15 acted to reduce in the cholesterol contents from 5 weeks. The results indicated that the Citrus-F-15 with rich flavonoids might be main source alleviating the vascular diseases and obesity in human diet.

This study was conducted to analysis the reason for implementing HACCP system, advantage and disadvantage of HACCP system implemented laying hen farm. The study was carried out by randomly selected fifteen laying hen farms located in all around Korea. All data were collected from fifteen laying hen farms before and after the implementation of HACCP system. The results were as follows: The egg production rate, livability rate and monthly used animal medicine fee did not changed after HACCP system implementation. However, monthly used disinfectant fee tended to be higher in HACCP farm compared to non-HACCP farm. 26.92% of the laying hen farmer responded enhancement of their farm competitiveness as the major propose for implementing HACCP system. The advantages of HACCP implemented laying hen farms were methodical farm management (22.39%), improvement of awareness (21.18%), improvement of the farm sanitation management level (15.30%), safety egg production (15.05%), productivity enhancement (7.29%), reduction of mortality rate (6.82%), and improvement of labor's welfare (5.89%). The disadvantages of HACCP implemented laying hen farms were HACCP recording (43.30%), alteration of consciousness (22.60%), HACCP monitoring (11.11%), HACCP education (9.97%), HACCP verification (6.90%), and A high turnover of labor (6.13%). In conclusion, implementation of HACCP system to laying hen farm did not affect on the productivity or the use of animal medicine. However, the HACCP system may enhance safety and sanitation of egg production for consumer.
