Abstract
OBJECTIVES To estimate the effects of an oral vitamin supplementation on cognitive function in the elderly, 254 elderly people(experiment group) who were received an oral vitamin supplement for one-year was compared with 292 elderly who were treated as the control group in Koje city during the study period(from February 1997 to March 1998).METHODS The cognitive function was tested by mini-mental state examination Korea(MMSE-K). Multiple regression analysis was done to control other confounding variables such as gender, age, educational level, smoking, alcohol, a past 15-day medical history, satisfaction for living cost, family number, cognitive function of the baseline survey.RESULTS In the baseline survey, the prevalence of cognitive impairment was 31%(mild impairment 12.5% and severe impairment 18.5%). There was a significant difference(0.76) in cognitive change in the elderly between two groups, 0.68 improved in the experiment group and 0.08 worsen in the control group(p<0.01). In multiple regression analysis, the significant variables were an oral vitamin supplementation, a past 15-day medical history, family number, cognitive function of baseline survey(p<0.05). The improvement of cognitive function was observed in those who do not have a past 15-day medical history, have a large family number, and have a low cognitive function of the baseline survey.CONCLUSIONS It appears that an oral vitamin supplementation was effective in improving the cognitive function in the elderly and more effective in the cases with abnormal cognitive function.

Abstract
E1 tor cholera epidemic have been reported eight times in Korea since 1963. Researchers suspected unattempted importation of cholera bacteria from foreign countries or artificial germination by some people. No researchers have made hypotheses of environmental reservoir as the sources of cholera epidemics until in 1991 in Korea. This study focuses on the aquatic reservoir as the potential source of cholera epidemic. A total of 68 cholera patients were noted in 1995 and only two in 1996. Authors argue for aquatic reservoir as the source of 1995, 1996 cholera epidemic and designate sea fishes as the vehicle of cholera infection The national Institute of Health team cultured Vibrio cholera O1, from the samples of sea water from Kangwha county in September 1995. The sporadic Occurrence of cholera patients around the country who have not traveled out of town support aquatic environmental reservoir as the source of 1995, 1996 cholera epidemic in Korea.
