In order to find the factors associated with the death of hypertensives, 12 year follow-up study for 267 hypertensives whose average blood pressure were 140/90 mmHg or above during their first health screening in 1979-1980 at YongJin Township, Wanju Country, North Cholla Province by the Community Health Team of Chonju Presbyterian Medical Center. The study results are as follows : 1. Initial general characteristics of hypertensives were studied. The age distribution of studied hypertensives showed 27.3% in 40-49 years, 25.8% in 50-59 years, 29.6% in 60-69 years and 17.2% In 70 + years old group. Marital status showed that 82.8% of hypertensives had their wife or husband. 74. 5% were employed on agriculture. 56.5% of hypertensives were illiterate. 2. Among the hypertensives, 91.6% of male and 22.8% of female reported that they were smokers. 82.6% of hypertensives had body mass index lower than 25 Kg/$m^2$. 46.8% of average systolic blood pressure were 160mmHg or above and 54.3% of average diastolic blood pressure were 95mmHg or above. 3. Twenty percent of hypertensives reported that they were treating hypertension at the beginning of follow up, while 68.5% reported that they were not treated. 28.1% reported that they were treating hypertension within 6 months before last follow-up. but 69.3% reported that they were not treated for hypertension within Ii months before last follow up. So 50.6% were classified as never treated group and 41.2% as treated group. 4. Average blood pressure for initial 3 years were calculated. The change of average systolic blood pressure was observed as $161.3{\pm}19.4mmHg$ at the first year, $145.6{\pm}28.0mmHg$ at the second year and $141.4{\pm}37.2mmHg$ at the third year. Average diastolic blood pressure were changed from $96.2{\pm}14.4mmHg$ at the first year to $90.6{\pm}18.6mmHg$ at the second year and $86.4{\pm}22.9mmHg$ at the third year. 5. By the follow-up of hypertensives, 54 hypertensives (46.2%) among 117 male hypertensives and 50 hypertensives (33.3%) among 150 female hypertensives died for 12 years. 42.6% of male death and 52.0% of female death were caused by cerebrovascular diseases. 6. Through univariate statistical test about the association between general characteristics or cardiovascular risk factors of hypertensives and mortality for 12 years, age variable among male and among female age, marital status, occupation. educational level. systolic blood pressure and treatment status were shown as significant variable to influence upon the mortality. 7. By multiple logistic regression analysis, among male age and systolic blood pressure were selected as significant variable to be associated with the total mortality for 12 years. Among female age, systolic blood pressure and treatment status were selected as statistically significant variable to be associated with the total mortality for 12 years.

Objectives : In order to obtain the clinical type of facial palsy sequelae and try to make the treatment protocols for each, I observed patients who visited Gunpo-Wonkwang oriental medicine center with Bell’s palsy sequelae that were treated over three months. Methods : I make the value standard of muscle paralysis, contraction, synkinesis and acquired the results as follows. Results and Conclusions : 1. The distribution of age and sex was as follows : females of 41-50 years were the most common demographic, females of 51-60 years and males of 31-40 years were the second, males of 51-60 years were the third, females of 21-30 years and males of over 60 years were the fourth, and males of 41-50 years were the fifth. 2. The distributions of period of disease were as follows : 3-6 months was the most, 12-18 months was the second, 6-12 months and over 24 months was the third, and 18-24 months was the fourth. 3. The sequelae distributions of disease were as follows. In the group of 3-6 months, 12 persons (80%) showed palsy and atrophy, 10 persons (66.6%) showed synkinetics. In the group of over 6 months, all patients showed muscle palsy, muscle atrophy and synkinetics. All groups showed lower sensitivity of muscles, but the group of 18-24 months and the group of over 24 months showed more. Tinnitus was shown by the groups of 12-18 months and 3-6 months. Facial muscle pain was shown by the group of3-6 months only, Crocodile's tear was shown by the groups of 18-24 months and over 24 months. 4. The total palsy rates of sequela patients and palsy rates by muscle for disease period were as follows. The total palsy rate was 27.94%; the palsy rates for the group of 6-12 months and the group of over 24 months was lower than the total palsy rate. The rates of the groups of 3-6, 12-18, 18-24 months were higher than the total palsy rate. The palsy rate of zygomatic minor, levator labii superior muscle was higher than the total palsy rate for all groups. 5. Synkinetics manifestation rates by disease period were as follows. Total synkinetics manifestation rate was 73.81 %; the manifestation rate of the group of 6-12 months was lower than total synkinetics manifestation rate. For the groups of 12-18, 18-24, and over 24 months it was more than the total synkinetics manifestation rate. The group of over 24 months, total synkinetics induced by orbicularis oculi muscle and orbicularis oris muscle. 6. Facial muscle atrophy rates by disease period were as follows. Total atrophy rate was 5.26%; in the groups of 6-12, 18-24, over 24 months, the atrophy rates were higher than the total atrophy rate. The groups of 3-6 and 12-18 months showed lower than the total atrophy rates, while the atrophy of the levator palpebrae superioris muscle and levator palpebrae inferioris muscle was higher than in other groups.

The durability of the xenograft cardiac substitute valves is of a great concern on the clinical grounds. Four groups of tc tal and consecutive patients to the end of study operated on between 1976 and 1984 were Group ISM, 291 patients of MVR, ISA, 65 patients of AVR, and ISMA, 107 patients of MVR+AVR with the standard Ionescu-Shiley bovine pericardial valve, and H, 163 patients of valve replacement with the Hancock porcine aortic vlave. Operative mortality was 5.2%[ISM], 10.8%[ISA], 7.5%[ISMA] and 6.1%[H]. Early survivors were followed up for a total of 1148.3 patient-years[pt-yrs] [ISM], 271.2 pt-yrs [ISA], 488.1 pt-yrs[ISMA] and 822.9 pt-yrs[H]. Linearized late mortality was 2.1% /pt-yr [ISM], 1.l%/pt-yr[ISA], 1.8%/pt-yr[ISMA] and 1.8% /pt-yr[H]. Thromboembolic complication was experienced at the linearized rate of 1.045% /pt-yr [ISM], 1.475%/pt-yr[ISA], 0.615%/pt-yr[ISMA] and 1.822%/pt-yr[H], and bleeding complication at the rate of 0.871% /pt-yr[ISM], 0.63% /pt-yr[ISA], 0.205% /pt-yr [ISMA] and 0.729%a /pt-yr[H], respectively. Prosthetic valve endocarditis occurred at the rate of 0.610% /pt-yr[ISM], 1.475% /pt-yr[ISA], 1.639% /pt-yr[ISMA] and 0.972% /pt-yr[H]. The linearized annual incidence of primary tissue failure was 1.655%/pt-yr[ISM], l. 475%/pt-yr[ISA], 1.639% /pt-yr[ISMA], 2.187% /pt-yr[H] and 1.785% /pt-yr[Group HM : MVR with Hancock valve]. The incidence of tissue failure was significantly high in the patients younger than 30 years of age compared with the older patients. The actuarial survival was 87.7$\pm$2.5% at 10 years[ISM], 94.3$\pm$3.2% at 11 years[ISA], 89.6$\pm$3.4% at 10 years[ISMA] and 81.3$\pm$6.6% at 12 years[HM], The freedom from thromboembolism was 93.2$\pm$2.0% at 10 years[ISM], 90.6$\pm$4.6% at 11 years[ISA], 95.8$\pm$2.6% at 10 years[ISMA] and 80.9$\pm$11.1% at 12 years[HM], And, the freedom from primary tissue failure was 84.2$\pm$3.8% and 28.1$\pm$23.0% at 9 and 10 years[ISM], 60.4$\pm$16.9% at 11 years[ISA], 62.3$\pm$12.7 at 10 years[ISMA] and 65.6$\pm$9.8% at 12 years[HM]. In conclusion, the standard Ionescu-Shiley and the Hancock bioprosthetic valves are excellent in their antithrombogenicity and long-term survival. However, the features of the structural failure with the prolonged follow-up beyond 10 years appear to be guarding, and the clinical indications of these bioprostheses seem to be quite limited.

Purpose: The aim of this study is to investigate the changing prevalence rate of Helicobacter pylori infection in children, of different age groups, with recurrent abdominal pain over a 10-year period. Methods: Children with recurrent abdominal pain who visited the pediatric outpatient clinic at university hospital were screened for H. pylori. Children were divided into 3 age categories of 4-5, 6-11, and 12-16 years. To study the changes in the annual prevalence rates of H. pylori infection, the study period was divided into 3 time periods: 2004-2007, 2008-2010, and 2011-2014. Urea breath test was performed for all children aged 4-16 years, with a cut-off value of 4.0‰ for children aged ${\geq}6$ years and 7‰ for children aged <6 years. Results: A total of 2,530 children (1,191 boys) with a mean age of $10.0{\pm}3.0years$ (range, 4.0-16.9 years) were included in the study. The total prevalence of H. pylori infection was 7.4% (187/2,530). The prevalence rate of H. pylori infection in children with recurrent abdominal pain was 8.0% (70/873) in 2004-2007, 7.7% (51/666) in 2008-2010, and 6.7% (66/991) in the 2011-2014. Nevertheless, a significant difference was observed in the prevalence rate between children <12 years old and ${\geq}12$ years of age (p=0.018). Conclusion: The prevalence of H. pylori infection in Korean children with recurrent abdominal pain was 7.4%, showing no significant decrease in the last 11 years; however, the prevalence rate in children <12 years old was significantly lower than that in those ${\geq}12$ years old.

Objectives : To investigate the progress, characteristics, and reasons of CV12 moxibustion that King Sukjong of Joseon Dynasty had experienced 31 years since 1684. Methods : This study mainly extracted the records and related records about CV12 moxibustion of King Sukjong and relevant records from Seungjeongwon Ilgi, and analyzed them. Aside from that, medical books wrote at that time and relevant records were additionally investigated. Results : King Sukjong cauterized CV12 or other CV12 related acupoints with moxa 21 years out of his 31 years from 1684 to 1714. The cautery period was usually between late January and mid February. He had 100 pieces of moxa for cautery. On the last day of his moxibustion, he cauterized ST36 with moxa. The moxibustion process consisted of the following steps: suggestion or requirement of moxibustion, decision of date and time, and moxa cautery. In 1684, the reason why King Sukjong cauterized CV12 with moxa was to treat his joint pain and nauseous symptoms. The effect can be found in Donguibogam, many other Korean medical books, and other general books at that time. In 1685, he began to cauterize CV12 with moxa to prevent diseases. Since then, most moxa cautery on CV12 had been performed in the same context. Conclusions : For 21 years, King Sukjong repeatedly cauterized CV12 with moxa. The moxa therapy was conducted to prevent diseases mostly. And King Sukjong had a lot of interest in the therapy. For the reasons, the therapy had repeatedly been performed so long.

Objective : This study was performed to find out the difference of symptoms between rhinitis and sinusitis in young patients who were diagnosed by PNS plain radiograph( PNS series), Methods: We did statistical analysis about 147 new outpatients under 12 year-old who had visited the department of ophthalmology, otolaryngology, dermatology in Kyung Hee Oriental Medicine Center from March 2, 2006 to February 29, 2008. All of the patients were diagnosed by PNS series and we divided the patients with two groups; rhinitis group and sinusitis group. We checked the OPD records and explore the distribution on sex, experience of past western therapy, age and duration. Then we divided symptoms into nine; 'nasal obstruction', 'purulent rhinorrhea', 'cough & sneezing', 'watery rhinorrhea', postnasal drip', 'sputum', 'head problem', 'snoring & throat discomfort' and 'epistaxis'. We also divided age into 2 groups: $0\sim7$ years old and $8{\sim}12$ years old. We carried out chi-square test as a statistical method. Results : The results were as follows. 1. Sinusitis group were 102(69.5%); 62 have only sinusitis. 40 have both sinusitis and adenoidal hypertrophy. Rhinitis group were 45(30.5%); 13 have adenoidal hypertrophy and 32 were negative. 2. Male were 98(sinusitis 65, rhinitis 33), female were 49(sinusitis 37, rhinitis 12). 3. Patients who had experienced past western therapy were 120(sinusitis 81, rhinitis 39), no experienced patients were 27(sinusitis 21, rhinitis 6). 4. Distribution on age of sinusitis was 1(1 yr), 2(2 yrs), 3(3 yrs), 15(4 yrs), 15(5 yrs), 23(6 yrs), 13(7 yrs), 12(8 yrs), 8(9 yrs), 5(10 yrs), 1(11 yrs), 4(12 yrs). Distribution on age of rhinitis was 1(1 yr), 0(2 yrs), 1(3 yrs), 1(4 yrs), 9(5 yrs), 5(6 yrs), 3(7 yrs), 5(8 yrs), 1(9 yrs), 8(10 yrs), 6(11 yrs), 5(12 yrs), 5. Duration of sinusitis was 20(<2 months), 6($2{\sim}3$ months), 11($3\sim6$ months), 34($6\sim12$ months), 31(>12 months) and of Rhinitis was 11(<2 months), 0($2\sim3$ months), 5($3\sim6$ months), 18($6\sim12$ months), 11(>12 months) 6. Distribution on symptoms, sinusitis patients were 86(nasal obstruction), 52(purulent rhinorrhea), 46(cough & sneezing), 38(watery rhinorrhea), 41(postnasal drip), 23(sputum), 18(head problem), 15(snoring & throat discomfort), 6(epistaxis). The each symptom and sinusitis have no relation by chi-square test. 7. The number of patients who were 0 $\sim$ 7 years old was 92: sinusitis 72(49%), non-sinusitis 20(13.6%). The number of patients who were 8 $\sim$ 12 years old was 58: sinusitis 30(20.4%), non-sinusitis 25(l7%). By chi-square test(confidence level 95%), sinusitis and age under 7 have a significant relation(p=0.003). Conclusions : There is no relation between rhinologic symptoms and sinusitis. Patients under 7 years old with rhinologic symptoms tend to have sinusitis.

This study was carried out to know physical growth and development, physical and nutritional indices and body fat weight and so forth by semi-longitudinal research method to measure body height, body weight, chest girth and sitting height of 260 of general high school and 306 of vocational high school 3rd grade students who are living in Seoul and born from 1966 March 1st to 1967 Feb.28th. The results are as follows: 1) Physical growth and development Growth in terms of body height showed one step straight linear development, andthat of body weight showed two step straight linear development in each section in high school. The age of cross over between two sexes of general high school students was between 10.6 to 12. 3 years in body height, between 10.8 to 13 years in body weight, between 11.2 to 14.6 years in chest girth and between 10 to 13 years in sitting height. The age of cross over between two sexes of vocational high school students was between 10.5 to 12.5 years in body height, between 10.5 to 12.5 years in body weight, between 10.5 to 12.5 years in chest girth and between 10.5 to 12.5 years in sitting height. In this periods, female group was superior to male group and after that male group was superior to female group again. The growth of vocational school students was superior to that of general school students in both sexes in terms of body height and body weight significantly. 2) Physical growth and nutritional indices In all cases of relative body weight, relative chest girth and relative sitting height, it was found to be increasing thereafter with advancing ages. In cases of $R{\"{o}}hrer$ index and Kaup index, it was found to be reaching to normal state thereafter with advancing ages. In each case of Vervaeck and Pelidisi index, it was found to be increasing and reaching to normal state thereafter with advancing ages. 3) Total body fat by vital measuring method Average values of body surface area, body volume and body density are measured indirectly by using the body height and body weight as Table 12, 13 and 14. The rate of body fat weight of general high school students was from minimum $11.96{\pm}3.53%(3.33{\pm}1.10kg$) to maximum $18.25{\pm}6.46%(9.08{\pm}2.01kg$) in male and from $25.88{\pm}3.62%(7.96{\pm}0.78kg$) to $43.00{\pm}7.22%(12.91{\pm}1.21kg$) in female. The rate of body fat weight of vocational high school students was from minimum $11.20{\pm}2.88%(3.32{\pm}1.13kg$) to maximum $17.16{\pm}5.88(10.83{\pm}3.16kg$) in male and from minimum $25.11{\pm}2.26%(7.91{\pm}0.89kg$) to maximum $42.16{\pm}7.96%(13.22{\pm}1.75kg$) in female.
