A survey was conducted by the staff of the College of Medicine and School of Public Health, Seoul National University in cooperation with Seoul Special City from 1 December 1967 through 28 February 1968, on such events as delivery, death, abortion and pregnancy. The survey directed to a total population of 47,811 residing in 9,157 households led us to the following findings: 1. Two year averages of crude birth rate, crude death rate and natural increase rate were 30.1, 5.6 and 24.5, respectively. 2. Of all deliveries, home and hospital deliveries constituted 61.1 per cent and 35.5 per cent, respectively. 3. Deliveries other than hospital deliveries were found to be attended more often by mother-in-laws(26.5 per cent) than by doctors or midwives(23.4 per cent). 4. About 52 per cent of all women having experiences in pregnancy during the last two years had an experience of consulting a doctor at least one time throughout whole period of pregnancy. 5. In most cases scissors were used to cut umbilical cords, of which 71.0 per cent were not sterilized and only 28.3 per cent sterilized. 6. In many cases placenta was incinerated(48,2 per cent) and on many other occasions it was thrown away into water(28.3 per cent). 7. Cement page(37.4 per cent), gauze and absorbent cotton(29.8 per cent)were found to be most frequently used to receive new-born babies. 8. In 1966 8.8 per cent of the women had at least one abortion induced and in 1967 the percentage was 9.2 per cent. 9. Nearly all(95.8 per cent) of the induced abortions reportedly were done at doctor's clinics. 10. Of all the abortions induced 65.3 per cent were done by specialists in obstetrics, 30.3 per cent by general practitioners and 2.7 per cent by midwives. 11. Those who experienced spontaneous abortions were 1.9 per cent of all women both in 1966 and 1967. 12. About 9.2 per cent of women investigated were found to be currently pregnant. 13. Age specific death rate turned out to be highest among those under 1 year of age. 14. Ten major causes of death in their order of frequency were: 15. Places of death can be classified into homes(75.3 per cent) and hospitals(13.2 per cent). 16. Method of disposing of corpses comprised burials(54.2 per cent) and cremations(44.6 per cent). 17. Infant, neonatal and hebdomadal mortality rates have been computed at 32.2, 18.9 and 13.7, respectively. 18. Infants were found to have died either at homes(81.5 per cent) or at hospitals(18.5 per cent). 19. Birth registrations had been done for about 18.5 per cent of the dead infants.

PURPOSE: The purpose of this study was to compare smoking prevalence and risk factors of smoking between Korean and Korean-Chinese middle school students. METHODS: Data was collected from seventh and eighth grade students from 12 schools in Korea and 6 schools in China. Descriptive statistics, Chi-square test, and t test were performed. RESULTS: For data analysis 10,002 usable surveys were utilized. The smoking prevalence was higher in Korean-Chinese students than in Korean students. Risk factors, such as father smoking, friends smoking, gender, grade, academic achievement, alcohol use, and family income were associated with current smoking, and the differences in the two samples were significant. Korean-Chinese students were more likely than Korean students to have friends who smoked and a father who smoked. Smokers had a significantly higher rate of friends smoking, father smoking, and alcohol use. Korean-Chinese male students smoking prevalence was more than three times higher than Korean students. Korean students could sense a more anti-tobacco atmosphere in their environment. Korean-Chinese students were more likely than Korean students to perceive that it was easy to buy cigarettes and to smoke cigarettes in a public computer room. CONCLUSION: These results highlight the differences of smoking prevalence and risk factors between Korean-Chinese students and Korean students. The findings may help health educators and researchers to better understand adolescent smoking and risk factors cross culturally and aid in the development of more effective education programs, which could lead to preventing tobacco use among these populations.

Two new species, Thelopsis ullungdoensis and Phylloblastia gyeongsangbukensis are described from Ullung-Do (Island), South Korea. The closest relatives from Europe and Korea are epiphytic Thelopsis flaveola which differs by their immersed or semi-immersed yellow ascomata, ascospores without halo and their habitat of smooth bark (mainly Fagus) in humid and cold climates. Thelopsis gangwondoensis differs by its bigger semi-immersed ascomata (600–700 µm in diam.), oblong halonate ascospores (8–12 × 6–8 µm) and its habitat of smooth bark of deciduous trees. P. gyeongsangbukensis differs from its relatives within the genus in having 5-septate ascospores (22–26 × 6–8 µm), semi-immersed, subglobose ascomata with a flattened top (250–400 µm) and a thin, matt, uneven gray-brown to gray-green continuous thallus without isidia.

Background and Objectives:
The prognostic or safety implication of renin-angiotensinaldosterone system inhibitors (RASi) in hypertrophic cardiomyopathy (HCM) are not well established, mainly due to concerns regarding left ventricular outflow tract (LVOT) obstruction aggravation. We investigated the implications of RASi in a sizable number of HCM patients.
Methods:
We enrolled 2,104 consecutive patients diagnosed with HCM in 2 tertiary university hospitals and followed up for five years. RASi use was defined as the administration of RASi after diagnostic confirmation of HCM. The primary and secondary outcomes were all-cause mortality and hospitalization for heart failure (HHF).
Results:
RASi were prescribed to 762 patients (36.2%). During a median follow-up of 48.1months, 112 patients (5.3%) died, and 94 patients (4.5%) experienced HHF. Patients using RASi had less favorable baseline characteristics than those not using RASi, such as older age, more frequent history of comorbidities, and lower ejection fraction. Nonetheless, there was no difference in clinical outcomes between patients with and without RASi use (log-rank p=0.368 for all-cause mortality and log-rank p=0.443 for HHF). In multivariable analysis, patients taking RASi showed a comparable risk of all-cause mortality (hazard ratio [HR], 0.70, 95% confidence interval [CI], 0.43–1.14, p=0.150) and HHF (HR, 1.03, 95% CI, 0.63–1.70, p=0.900). In the subgroup analysis, there was no significant interaction of RASi use between subgroups stratified by LVOT obstruction, left ventricular (LV) ejection fraction, or maximal LV wall thickness.
Conclusions
RASi use was not associated with worse clinical outcomes. It might be safely administered in patients with HCM if clinically indicated.

PURPOSE: The objective of this study was to measure secondhand smoke (SHS) exposure in personal computer (PC) rooms with the purpose of determining the strength of scientific evidence supporting the legislative ban on smoking in PC rooms located in the Republic of Korea. MATERIALS AND METHODS: From June to September 2012, particulate matter (PM2.5) and air nicotine concentration (ANC) were measured in the smoking and non-smoking areas of PC rooms in Goyang City, Korea. In 28 randomly sampled PC rooms, field investigators completed an observational questionnaire on building characteristics, smoking policies, and evidence of smoking. The geometric means (GM) of PM2.5 and ANC in smoking and non-smoking areas were compared. RESULTS: Evidence of smoking was identified in both the smoking and non-smoking areas of all PC rooms. The GMs of PM2.5 and ANC in both areas were high and did not differ significantly (174.77 μg/m3 and 48.95 μg/m3 in smoking areas; 93.38 μg/m3 and 41.30 μg/m3 in non-smoking areas). Overall PM2.5 concentrations were 5.5-fold higher than those listed in the World Health Organization guidelines. CONCLUSION: This study supported previous reports that a partial smoking ban did not protect individuals from SHS exposure. Furthermore, the results from our study suggest how research can support policy. Countries in which smoke-free policies are not yet comprehensive may find our results useful.

The aims of this study were to evaluate obesity-related dietary behaviors and to determine long-term exercise effects on obesity and blood lipid profiles in elderly Korean subjects. A total of 120 subjects, aged 60-75 yr, were recruited, and obesity-related dietary behaviors were determined. An exercise intervention was conducted with 35 qualified elderly females for 6 months, and body composition and blood lipids were measured 6 times at 4 week intervals. At baseline, mean BMI (kg/m2) was 24.8 for males and 23.1 for females. The females had better eating habits than the males and were more concerned with reading nutrition labels on food products (P < 0.001); they also preferred convenience foods less than the male subjects (P < 0.05). Obese individuals were more likely than overweight or normal weight individuals to misperceive their weight (P < 0.001). Those with a high BMI responded feeling more depressed (P < 0.01), lacking self-confidence (P < 0.01), and feeling isolated (P < 0.01), as well as having more difficulty doing outdoor activities (P < 0.01). After exercise, body fat (%) and WHR were significantly reduced (P < 0.05), while body weight and BMI were also decreased without statistical significance. Total cholesterol and blood HDL were significantly improved (207.1 mg/dl vs. 182.6 mg/dl, HDL: 45.6 mg/dl vs. 50.6 mg/dl, P < 0.05). Other benefits obtained from exercise were improvements in self-confidence (26.4%), movement (22.6%), stress-relief (18.9%), and depression (13.2%). In conclusion, elderly females had better eating habits and were more concerned with nutrition information and healthy diets compared to elderly males. However, misperceptions of weight and obesity-related stress tended to be very high in females who were overweight and obese, which can be a barrier to maintain normal weight. Long-term Danhak practice, a traditional Korean exercise, was effective at reducing body fat (%) and abdominal obesity, and improved lipid profiles, self-confidence, and stress.

Pulmonary edema is a major cause of mortality due to acute lung injury (ALI). The involvement of protein kinase C-delta (PKC-delta) in ALI has been a controversial topic. Here we investigated PKC-delta function in ALI using PKC-delta knockout (KO) mice and PKC inhibitors. Our results indicated that although the ability to produce proinflammatory mediators in response to LPS injury in PKC-delta KO mice was similar to that of control mice, they showed enhanced recruitment of neutrophils to the lung and more severe pulmonary edema. PKC-delta inhibition promoted barrier dysfunction in an endothelial cell layer in vitro, and administration of a PKC-delta-specific inhibitor significantly increased steady state vascular permeability. A neutrophil transmigration assay indicated that the PKC-delta inhibition increased neutrophil transmigration through an endothelial monolayer. This suggests that PKC-delta inhibition induces structural changes in endothelial cells, allowing extravasation of proteins and neutrophils.
