In order to examine the actual condition of smoking, the change of knowledge and the attitude on smoking of the students attending junior and senior high schools in Korea, the survey was performed six times ranging from 1988 to 1997. The first two years, the survey was performed only for male students. Since 1991, both male and female students were surveyed. The students in junior and senior high school were selected by a random sampling method and surveyed by mail. In this survey, the number of classes of Junior and senior high schools in Korea was a sampling unit, and the classes were selected in proportion to the number of classes of each city and each county. The total number of respondents was 3,437 in 1988, 3,055 in 1989, 6,087 in 1991(2,923 of male, 3,164 of female), 7,067 in 1993(3,162 of male, 3,905 of female), 5,412 in 1995(2,598 of male, 2,814 of female), 4,754 in 1997(2,281 of male, 2,473 of female). The results obtained from the data analysis are as follows; 1.The ratio of smokers among male junior high school students has increased from 1.8% in 1988 to 3.9% in 1997. The ratio of smokers among female junior high school students has increased from 1.2% in 1991 to 3.9% in 1997. The ratio of smokers among male senior high school students has increased from 23.9% in 1988 to 35.3% in 1997. The ratio of smokers among male senior high school students has increased from 23.9% in 1988 to 35.3% 1997. And the ratio of smokers among female senior high school students has increased from 3.0% in 1991 to 8.7% in 1997. Especially the ratio of smokers among female junior high school students is same as that of male in 1997. 2. With respect to areas, the number of current smokers and the experienced ones was higher in the county than in the city in 1988. But in 1997, the number of current smokers and the experienced one is higher in the city than in the county. 3. In respect of whether or not there is a smoker among the member of a family, the odds ratio of smoking among the male senior high school students was 1.70 in 1988 and 1.94 in 1997. the odds ratio of smoking among female senior high school students was 1.43 in 1991 and 1.98 in 1997. This result showed that the effect of family smoking on adolescent smoking has not decreased.

The Korean Dementia Association (KDA) has been organizing biennial international academic conferences since 2019, with the International Conference of the KDA (IC-KDA) 2023 held in Busan under the theme ‘Beyond Boundaries: Advancing Global Dementia Solutions.’ The conference comprised 6 scientific sessions, 3 plenary lectures, and 4luncheon symposiums, drawing 804 participants from 35 countries. Notably, a Korea– Taiwan Joint Symposium addressed insights into Alzheimer’s disease (AD). Plenary lectures by renowned scholars explored topics such as microbiome-related AD pathogenesis, social cognition in neurodegenerative diseases, and genetic frontotemporal dementia (FTD). On the first day, specific presentations covered subjects like the gut–brain axis and neuroinflammation in dementia, blood-based biomarkers in AD, and updates in AD therapeutics. The second day’s presentations addressed recent issues in clinical neuropsychology, FTD cohort studies, and the pathogenesis of non-AD dementia. The Academic Committee of the KDA compiles lecture summaries to provide comprehensive understanding of the advanced dementia knowledge presented at IC-KDA 2023.
