Objective As aging progresses, clinical characteristics of elderly patients in the emergency department (ED) vary by age. We aimed to study differences among elderly patients in the ED by age group. Methods For 2 years, patients aged 65 and older were enrolled in the study and classified into three groups: youngest-old, ages 65 to 74 years; middle-old, 75 to 84 years; and oldest-old, ${\geq}85years$. Participants' sex, reason for ED visit, transfer from another hospital, results of treatment, type of admission, admission department and length of stay were recorded. Results During the study period, a total 64,287 patients visited the ED; 11,236 (17.5%) were aged 65 and older, of whom 14.4% were 85 and older. With increased age, the female ratio (51.5% vs. 54.9% vs. 69.1%, P<0.001), medical causes (79.5% vs. 81.3% vs. 81.7%, P=0.045), and admission rate (35.3% vs. 42.8% vs. 48.5%, P<0.001) increased. Admissions to internal medicine (57.5% vs. 59.3% vs. 64.7%, P<0.001) and orthopedic surgery (8.5% vs. 11.6% vs. 13.8%, P<0.001) also increased. The ratio of admission to intensive care unit showed no statistical significance (P=0.545). Patients over age 85 years had longer stays in the ED (330.9 vs. 378.9 vs. 407.2 minutes, P<0.001), were discharged home less (84.4% vs. 78.9% vs. 71.5%, P<0.001), and died more frequently (6.3% vs. 10.4% vs. 13.0%, P<0.001). Conclusion With increased age, the proportion of female patients and medical causes increased. Rates of admission and death increased with age and older patients had longer ED and hospital stays.
A total of 2,580 sera of the patients who were consulted to the serology laboratory of the Seoul National University Hospital were collected in 1990. The sera were screened by micro-ELISA to detect IgG antibody reacting with Pneumocystis carinii antigen. The absorbances were 0.00 to 1.41 and mean 0.27±0.253. As the positive criterion was set absorbance 0.2 or more with 70% sensitivity, total positive rate was 44.4oA. Mean absorbances and positive rates were higher in children than in adults; 0.40 and 62.9% in 0 year group, 0.50 and 81.2% in 1 year group, 0.41 and 66.0% in 2-3 year group, 0.33 and 61.4% in 4-5 year group, 0.25 and 42.3% in 6-10 year group respectively. In the age groups over 11 years, the absorbances were in range of 0.16 to 0.23 and the positive rates were 26.1% to 41.5%. The present level of absorbances and positive rates could be regarded similar with those in normal Korean population. The present findings suggest that most humans are exposed to Pneumocystis within 2 years after birth and meet much less new antigenic challenge after 11 years in Korea.
The usage of appropriate disinfectants is essential for infection control in dental hospitals, dental clinics. Inadequate use of disinfectants is the cause of human or environmental toxicity and is a waste of cost. This study was aimed to assess the level of knowledge on the disinfection and chemical disinfectants among dental workers in dental hospitals, dental clinics. It's ultimately intended to serve as a basis for the preparation of more effective, appropriate educational programs on the disinfection and manuals on the use of disinfectants for dental workers. This study enforced a questionnaire with 184 dental workers employed in dental hospitals, dental clinics from 15 Aug. to 15 Sep. 2007, in the area of Daejeon. The obtained result were as follows; 1. The population sociological feature of dental hospital and dental clinic showed that significant differences of dental service career(pM0.039). Dental service career of dental workers shows; below 3 years 42.9%, 4~6 years 34.7%, more than 7 years 22.4% in dental hospitals, below 3 years 30.4%, 4~6 years 26.7%, more than 7 years 43.0% in dental clinics(pM0.039). 2. The average score of dental workers knowledge in 'Critical item soaks in high-level disinfectants for 20minutes was 2.73V0.49 point, got from knowledge of dental instrument is appropriate to immerse before sterilization in the dental device disinfection(pM0.002). 3. In the general disinfection which it follows in education experience of chemical disinfectants direction for use, 'Direction for use by Spaulding process classification' responded that the correct answer was the education experience dental workers 60.0%, the education non-experience dental workers 39.5%(p=0.026). 4. In the dental device disinfection which it follows in education experience of chemical disinfectants direction for use. 'High level disinfection is not applied for the non-critical items and equipment' responded that the education experience dental workers 49.2%, the education non-experience dental workers 31.9%(pM0.045), 'Semi-critical items is applied same method in presence of the infection disease which it acts responded that the education experience dental workers 44.6% answer back, the education non-experience dental workers 24.4%(pM0.017). 5. 'A hand disinfectants of anticeptics have effect' the education experience dental workers 78.5% answer back, the education non-experience dental workers 52.9%(pM0.003). 1t uses with hand disinfectants when the instruments which be imbrued and patient contact', the education experience dental workers 78.5% answer back, the education non-experience dental workers 62.2%(pM0.026), 'Boric acid solution uses for the skin disinfectants the education experience dental workers 52.3% answer back, the education non-experience dental workers is 37.0%(pM0.016), 'Gluconate have effective difference which it follows in chemical disinfectant consistency and the solution type' education experience dental workers 72.3% answer back, education non-experience dental workers 47.9%(pM0.004). 6. The education experience dental workers were appeared higher than the education non-experience dental workers in knowledge of the disinfection and chemical disinfectants. Consequently system and the specialty education which is standardized continuously must be provided to all dental workers.

Background: This study aimed to present the short- and midterm outcomes after complete atrioventricular canal defect (CAVC) repair using a single-patch technique. Methods: This study included 30 children who underwent surgical correction of the CAVC using a single-patch technique. Results: The median age of the patients was 5.7 months (interquartile range [IQR], 5.0-7.5 months), and 23 patients (76.7%) had type A CAVC. Fourteen patients (46.7%) were female and 17 (56.7%) had been diagnosed with Down syndrome. The in-hospital mortality rate was 0%. No deaths were observed during a median follow-up of 4 years (IQR, 3.5-5.0 years). Patients without Down syndrome were associated with late moderate mitral regurgitation (MR) (p=0.02). Late MR less than moderate degree was observed in 96.6%, 78.5%, and 50% of patients after 2, 4, and 5 years of follow-up, respectively, while late tricuspid valve regurgitation less than moderate degree was observed in 96.7%, 85.9%, and 59.0% of patients after 2, 4, and 6 years of follow-up, respectively. After a median follow-up of 4 years, only one patient had required surgical repair of a left ventricular outflow tract obstruction, which occurred 26 months after the first operation. Multivariable logistic regression analysis adjusted for the type of CAVC, sex, Down syndrome, age, and weight revealed that the absence of Down syndrome was a risk factor for late moderate MR (MR-2) (odds ratio, 0.05; 95% confidence interval, 0.006-0.50; p=0.01). Conclusion: A single-patch technique for CAVC surgical repair is a safe method with acceptable short- and midterm results.
This study was performed to investigate the age distribution with tooth calcification and degree of eruption of permanent teeth. For the study, healthy 184 patients from 5 to 19 years old without any previous serious dental treatment were randomly selected, and intraoral standard films and dental casts were taken for evaluation of stage of calcification and degree of eruption, respectively. Tooth calcification of 13 stages, designed by the author based on the Nolla's classification and eruption level of 4 or 5 degree was used. Data were processed by SAS/Stat program and the obtained results were as follows; 1. The age of root completed with open apex in lower posterior teeth were 13.8 years for first premolar, 14.0 years for second premolar, 10.5 years for first molar, and 14.2 years for second molar. There were no significant difference between right and left side. 2. As for the sequence of eruption, first molar was the first teeth erupted in upper arch, while central incisor was the first teeth in lower arch. In general, eruption of lower teeth were slightly earlier than the corresponding teeth of upper arch. 3. There were no difference of age of the same stage of development between Nolla's and the author's classification. From the results, the author's classification can be used for estimation of age with more finely in age of 8 to 15 years old. 4. Multiple regression equations for age with Nolla's(Ns) and the author's(Ks) classification of tooth calcification, and degree of eruption(DE) were as follow; Age(by #34) = 7.55 + 0.76Ks34 + 0.80DE34 - 0.72Ns34 Age(by #35) = 7.10 + 0.81Ks35 + 0.6IDE35 Age(by #37) = 6.61 + 0.82Ks37 + 0.5IDE37. Age(by #44) = 7.02 + 0.62Ks44 + 0.82DE44 Age(by #45) = 8.04 + 0.93Ks45 + 0.64DE45 - 0.89Ns45 Age(by #47) = 6.40 + 0.86Ks47 + 0.56DE47.
The consecutive 35 patients underwent isolated aortic valve replacement with the low-profile model of the Ionescu-Shiley pericardial xenograft valve from 1984 to 1991. Operative mortality was 2.9%, and early survivors were followed up for a total 136.1 patient-years[Mean$\pm$SD, 4.00$\pm$2.14 years]. The linearized late mortality was 2.204% /pt-yr. Three patients required rereplacement of the valve with overall valve failure rate of 2.204% /pt-yr: two for endocarditis and one for paravalvular leak. There was no case of primary tissue failure. The linearized annual rates of complication were: thromboembolism 0.735% /pt-yr, bleeding 0.735%pt-yr, and endocarditis 2.204% /pt-yr. The actuarial survival at 8 years of follow-up was 90.4$\pm$5.3%, and the probabilities of freedom from thromboembolism and from rereplacement were 95.6$\pm$4.4% and 88.2$\pm$6.7% at 8 years respectively. Although the low profile Ionescu-Shiley pericardial valve provided favorable clinical performance comparable with the standard model up to 8 years, it needs prolonged follow-up to assess the pattern of its durability.
This study was conducted to investigate the annual differences in food habits and dietary attitudes of new female college students enrolled in the department of food and nutrition for 6 years by questionnaire. The results were as follows: age, height, weight and body mass index(BMI) were no significant annual differences over study period. The average ratios of underweight, normal weight and above overweight groups classified by the BMI standard were 19.4%, 64.4% and 16.2%, respectively. There were no significant annual differences in the scores of food habits and dietary attitudes. The intake of milk showed the lowest scores among all the food habit items and the same annual tendencies for 6 years. Among food groups items, the mean intake scores of milk(p<0.01), fats and oils(p<0.001) and vegetables(p<0.05) differed significantly by year. Specifically, the intake scores of milk and vegetables decreased gradually throughout the study period and were significantly lower in 2008 than in 2003. Among dietary habits, the mean intake scores of sweets were significantly lower in 2003 and 2007 than in other years(p<0.001), and the mean intake scores of instant frozen foods were significantly higher in 2006 than during other years(p<0.05). The sum of health related items in 2007 was significantly lower than those during other years, and this was likely due to the lowest scores both of eating-out and alcohol intake in 2007 than in other years. Among dietary attitudes, the mean score of item 'Price of food is more important than nutrition.' was significantly lower in 2005(p<0.05). Food habit scores showed significantly positive correlation with dietary habits(r=0.733, p<0.01), food groups related habits(r=0.720, p<0.01), lifestyle related disease related habits(r=0.518, p<0.01), health related habits(r=0.422, p<0.01). Food habits and dietary attitudes showed highly significantly positive linear correlations each other(r=0.426, p<0.01). Dietary habits and food groups related habits showed highly significantly positive linear correlations(r=0.366, p<0.01). These results showed the same annual tendency with respect to food habit and dietary attitudes in newly enrolled college female students for 6 years. It is expected that food habit and dietary attitudes will be improved if systemic and proficient nutrition education is provided during their college period.
This study were conducted to investigate the viability and germination of dehisced Panax ginseng seeds stored for long period in the storage chamber with $5^{\circ}C\;and\;30{\%}$ humudity. The staining reaction times for viability test were 150 min, 90 in, 60 min at $0.1{\%},\;0.5{\%}\;and\;1{\%}$ triphenyltetrazolim chloride(TTC), respectively. the more the storage period, the less the healthy seeds ratio. It was $96.6{\%},\;89.2{\%},\;63.4{\%}$ for 1-year storage, 7-years storage, 9-years storage, respectively. Germination ratio were $84.0{\%},\;80.5{\%},\;73.5{\%},\;2.5{\%}$ for 1-year stroage, 6-years storage, 7-years storage and 9-years storage, respectively. Therefore it was confirmed that ginseng seed can be stored up to 6-7 years.

Authors analyzed sonographic findings of 59 cases of hepatic hemangioma, with had been diagnosed through examination in our Medical. dept, from Januray, 1985 to December 1989. The results of the analysis are as follows: 1) The hepatic hemangioma was found in 59 cases(0.33%) among the 17,714 insureds. 2) In all 59 cases who have hemangioma, hemangioma was found in 37 cases(0.35%) among the 10,724 insureds of male, and in 22 cases(0.31%) among the 6,990 insureds of female. 3) The possessing rate of hemangioma in male was increased by age regardless of sex-5/2,120 cases(0.24%) in $21{\sim}30$ years, 25/8,122 cases(0.31%) in $31{\sim}40$ years, 16/4,997 cases(0.32%) in $41{\sim}50$ years, 8/1,775 cases(0.45%) in $51{\sim}60$ years, and 5/359 cases(1.39%) in over 61 years. 4) The tumor involved right lobe of the liver in majority(71.4%) 5) The size of tumor was 10 lesions in under 10 mm, 58 lesions in $31{\sim}50$ mm, and 6 lesions in over 51 mm. The smallest tumor was 8 mm in diameter and the largest was 72 mm in diameter and 78 lesion(92.8%) were less than 50 mm in size. 6) Posterior acoustic enhancement was noted in 4 lesions among 68 lesions of less than 30 mm in long diameter, and in 4 lesions among 16 lesions more than 30 mm in long diameter. 7) Echographically most of the lesions presented as a round or oval high homogeneous echogenic mass, although a few mass appeared to be hypoechoic or Mixed echogenic. Finally a small round echogenic, sharply-marginated and internally homogeneous lesion is highly suggestive of hemangioma. If the hypoechoic lesion has homogeneous internal echoes and/or strong marginal echoes, it is also suggestive of hemangioma.
