This study aimed to analyze adult men's body sizes and shapes and suggest size specifications to provide preliminary data to academia and industries. A total of 814 adult men aged 30-44 were selected from the 7th Size Korea data, and 55 direct upper body measurement and calculation items were analyzed using SPSS 25.0. In individual Individual differences, thickness, circumference, and width were high, and height and length were low. Height above the waist base line and shoulder dimension decreased in early 40s age group, while height below the waist base line declined as age increased. In addition, buttocks shape changes were found in early 40s age group. According to factor analysis, 'upper body and upper-extremity horizontal size', 'torso height and upper extremity length', 'shoulder dimension', 'upper body length' and 'shoulder angle' were derived. Using clustering analysis, four different body types were classified: i) big abdomen with flat chest, ii) slender with big, raised shoulders, iii) dwarfish with small, droopy shoulders, and iv) obese with large shoulders. 'Slender with big, raised shoulders' was a typical body shape among men aged 30-44. In older participants, the 'big abdomen with flat chest' ratio was low, while 'obese with large shoulders' was more common. This study proposed size specifications by body type considering the above characteristics.

This study analyzes the difference in the awareness of Korean Unification among age groups based on survey data. It is verified by statistical model analyses that the ratio of agreement for Korean Unification increases with the age growth, but after the highest peak at the age group of 44 ~ 53 years, the ratio of agreement gradually decreases. The statistical model shows that the age group of 44 ~ 53 years old has 2.5 times higher odds of agreement than the age group of 24 ~ 33 years old and the odds of female to male is 0.56. Meanwhile, the ratio of increase in the agreement, aligned with the increasing age groups, shows 4.3 times higher for males than females. The difference in the ratio of agreement in the overall age groups is estimated to be contributed the most by the significant difference in the ratio of agreement for Korean Unification between the young male generation (in their 20s and 30s) and the middle-aged male generation (in their 40s and 50s).

Objective : This study explores whether and how the amount of smoking differs by economic status and perception among the men in working age. Methods : The study utilized the 4th wave of KoWEPS containing the items on perception of economic conditions. Analysis was conducted on ever-married men aged 30-54, who have capacity to work. It used 2 stage regression model methods to examine the mediation effect of perception on economic status. Results : The results shows that the negative perception on economic status has a positive effect on smoking. Disposable income affects smoking only through the perception of economic status. Employment status exerts both direct and indirect effect on smoking. Conclusions : These findings imply that less privileged economic status is related to smoking through anxiety or stress for the negative perception on it.

This study used raw data from the 2013-2015 National Health and Nutrition Survey, and conducted a multivariate logistic regression analysis to identify factors related to teeth extraction from Korean elderly aged 65 and older (4.037). As a result, the risk of tooth extraction was 1.84 times higher in males, 1.52 times in age 75 or older, 2.36 times higher in income, 2.04 times higher in income, and 1.44 times higher in smokers. The results were statistically significant as 1.49 times without oral examination and 2.30 times without dental treatment for 1 year. Through this, the current health behavior and oral health behavior can reinforce the basis of risk factors related to the need for tooth extraction. At the national level, we need to look for diversification.

Among 136 patients having undergone mitral valve surgery from September of 1994 through August of 1995 in Sejong Heart Institute, forty four patients(18 males, 26 females) underwent mitral valve reconstruction using prosthetic rings and their clinical results were evaluated. Patients'ages ranged from 5 to 63 years(mean age 38.2 years). Mitral valvular diseases were due to rheumatic origin in 30 patients(68%), degenerative in 13(30%), and congenital in one patient(2%). Mitral regurgitation(MR) was in 33 patients(76%), mitral stenosis 2(5%), and mitral stenoinsufaciency 9 patients(19%). The patients were divided into Carpentier's functional groups : type I, 5 patients(11%) : type I, 24 patients(55%) ; type III, 4 patients (9%) i and mixed(II + III), 11 patients(25%). Average number of anatomic lesions of mitral valve per patient was 3.7. The techniques included prosthetic ring amluloplasty(44 patients, 32 Carpentier ring and 12 Duran ring), leaflet mobilization(24, 55%), chordae shortening(23, 52%), chordae transposition(23, 52%), commissurotomy(16, 35%), leaflet resection(9, 20%), papillary muscle splitting(8, 18%), and chordae reimplantation(1, 2%). Average 3.4 surgical procedures were applied on mitral valve per patient. There were two hospital mortality and one reoperation due to development of MR(grade III) after 2 weeks. During the mean follow up of 12 months, patients improved in terms of functional class of the New York Heart Association, which was mean 3.0 preoperatively and 1.3 postoperatively. Doppler echocardiographic studies showed adequate valve area(2.07$\pm$0.11 cm2 mean $\pm$standard error), improved ventricular contractiliy in 41 patients(93%), ab ence of MR in 23(53%), trace MR in 18(42%), and garde II MR in 2 patients(5%).

We reviewed retrospectively the medical records of 600 elderly patients, over 65 years old who visited oral medicine. The ratio of the age group was composed of 65${\sim}$74 years old group was 63.7%, 75${\sim}$84 years old group was 32.2%, over 85years old group was 4.2%, and the patients were mostly females. The main chief complaint was composed of oral soft tissue problem(44.1%) and oromaxillofacial pain(39.0%). The majority of systemic diseases was composed of diseases of the circulatory system(30.1%), diseases of the musculoskeletal system and connective tissue(16.8%), endocrine, nutritional and metabolic diseases, and diseases of the digestive system(10.1%). The numerous pateints were diagnosed as soft tissue disease(32.0%), arthrogenous disease(24.1%), and myogenous disease(18.1%) of temporomandibular disease.Principally medication(43.9%), physical therapy(24.2%) were performed. 14.2% of all patients visited oral medicine with a letter of request written by other medical departments or local dental clinics, or referred from other departments in Chosun university dental hospital. These findings indicate epidemiologic characteristics on the elderly patients visited oral medicine. We hope that this study will play a basis in the future research about the elderly patients.

This study is to look at the risk of chronic diseases in adults and oral health behaviors affecting periodontitis by gender. This study selected 3,071 males aged 35 to 65, 4,273 females, and 7,344 people as the final subjects of the study using the sixth original data from the National Health and Nutrition Survey. In this study, subjective oral health classified under 'bad' presented 1.69 times(p<0.001) the risk of Periodontitis for males and 1.50 times(p<0.001) for females. There was a 2.01 times(p<0.001) of a risk of periodontitis for male and 1.40 times(p=0.001) of a risk for females. Smokers have a 1.68 times(p<0.001) of a risk for males and 2.07 times(p<0.001) of a risk for females, thus a higher risk for periodontitis for females. The risk of periodontitis was 1.44 times(p<0.001) of a risk for males and 1.30 times(p<0.05) for females when compared in normal hypertension. Obesity was at a rate of 1.199 times(p<0.05) as much for males in the non-military group, 1.202 times(p<0.05) that of females for periodontitis and putting females slightly more at risk. For diabetes, males were at risk of 1.28(p<0.05) whereas it being 1.53 times(p<0.05) for females, compared the average health female. In total, Males were found to be at the greatest risk of periodontitis, while women were at the highest risk for smoking. All parameters except smoking and diabetes show a higher risk of periodontitis for females. As males are more likely to have a higher risk of periodontitis than females, they are considered to be more interested in oral health care and need systematic oral health education and policies to prevent oral diseases.

Purpose : Enteroviruses are the most common cause of aseptic meningitis. The epidemics of aseptic meningitis in 1993 and 1996 were mostly caused by echovirus type 9. Identification of the causative virus of aseptic meningitis in epidemics, is very important not only for diagnosis but also for epidemiologic purpose. The purpose of this study was to identify the causative virus and investigate the relationship between aseptic meningitis, prevailed in Masan and surrounding areas in Kyoungsangnamdo in 1997, and its clinical manifestations. Methods : One hundred twenty eight cerebrospinal fluid(CSF) and 239 stool specimens were obtained from 239 patients(213 children and 26 adult patients) with aseptic meningitis were admitted to Masan Fatima Hospitals from March to October 1997. Viral isolation and serotype identification was performed by cell culture and immunofluorescent test. Enteroviruses not typed by immunofluorescent test was confirmed by reverse transcription-polymerase chain reaction(RT-PCR). Results : 1) The peak incidence was noted in June. 2) The age of 239 patients(pediatrics-213 cases, internal medicine-26 cases) that were diagnosed ranged from neonate to 35 years, the age of the patients of pediatrics ranged from neonate to 15years(mean 4.9 years), the age of the patients of internal medicine (above 16 years) ranged from 16 years to 35 years(mean 24.2 years). 3) Fifty-three(41.4%) of 128 CSF specimens were positive for enteroviruses, and 163(68.2%) of 239 stool specimens were positive for enteroviruses respectively. 4) Serotypes of 53 enteroviruses isolated from CSF were 16(30.2%) of echovirus type 30, 6(11.3%) of echovirus type 6, 1 of echovirus type 4, 4 of untyped echovirus, 1 of coxsackievirus type B5, and 24 isolates of untyped enteroviruses. Of 163 enterovirus isolated from stool were 72(44.2%) of echovirus type 30, 21(12.9%) of echovirus type 6, 1 of echovirus type 4, 17(10.4%) of undetermined subtyped echovirus, 1 of coxsackievirus type B5, 2 of A24, 3 of undetermined subtyped coxsackievirus type B, and 46 isolates of untyped enterovirus. Conclusion : There were epidemics of aseptic meningitis in the central areas of Kyoungsangnamdo from March to October 1997. The main causative organism was thought to be the echovirus type 30, and echovirus type 4, 6, coxsackievirus B5 and A24 were also thought to contribute to the epidemics.

A controlled and double blinded trial was performed to evaluate the effects of OPE supplementation on blood circulation in healthy male smokers. The study population consisted of 92 healthy male smokers aged $44.4{\pm}7.8$ years. The supplement group (n=49) received OPE containing 100 mg quercetin/day for 10 weeks, while the control group (n=43) received placebo powders. The prothrombin time and activated partial thromboplastin time increased significantly after OPE consumption, indicating the attenuated blood clot formation by OPE. In conclusion, these results indicate that the daily consumption of OPE (containing 100 mg quercetin) for 10 weeks exerts significant health benefits through the modulation of physiological functions including the blood circulation in male smokers.
