Purpose : Cardiovascular disease is major factor of mortality in worldwide. Previous studies shown that the socioeconomic factors, nutrition factors, health behavior factors, biological factors and co-morbidity are increasing a prevalence of cardiovascular disease. Method : This study examined the risk factors for cardiovascular disease among adults aged 30 years and older using the data from the 2012 to 2014 Korean National Health and Nutrition Examination Survey (KNHANES). The study participants were 7,555 Cardiovascular disease includes hypertension, stroke, angina pactoris, and myocardial infarction. Descriptive statistic and multivariates logistic regression were calculated. Result : The overall prevalence of cardiovascular disease was 31.16% in the participants. Cardiovascular disease was significantly associated with gender, age, income, education, marital status as socioeconomic factors in unadjusted model. After adjusting socioeconomic status variables, past smoker (OR 1.27, 95% CI 1.05-1.55), obesity (OR 7.14, 95% CI 4.21-12.11), skipping a meal (OR 2.79, 95% CI 2.46-3.16), HDL-C (OR 0.99, 95% CI 0.98-0.99) and WC (OR 1.06, 95% CI 1.05-1.07) were associated with cardiovascular disease. Conclusion : The results marked the importance of finding high risk groups and an early management of cardiovascular disease.

The present study was conducted to investigate the prevalence of PCV2 infection of the aborted pigs in Gyeongbuk province from April in 2004 to March in 2005. The prevalence of PCV1 and PCV2 infection was confirmed by the PCR method against 32 aborted pigs of 19 farms, which were requested of diagnosis of disease. Among 32 aborted pigs, abortions caused by PCVI were $7(21.9\%)$ heads and by PCV2 were $9(28.1\%)$ heads. Using PCR, the rate of PCV1 infection of 19 farms which were requested of diagnosis of disease is positive in $2(10.5\%)$ farms and $5(26.3\%)$ farms were positive in PCV2, and compositive infections of PCVI, PCV2 is $1(5.3\%)$ farms. Among 32 aborted the pigs, only PCV2 infection was one case $(3.1\%)$, compositive infections with abortion disease were 8 cases $(25\%)$, Compositive infections with abortion disease were most of the parvovirus infection $(84.2\%)$.

This study was carried out to investigate the epidemiological prevalence of diseases from birth to weaning in 66 dairy calves which were delivered from three stock farm in Chonbuk area. We examined body weight gain, incidence rate of diseases and population mortality rate in relation to age, season, environmental temperature and rearing management conditions for one year. The results of this experiment were as follows: Birth weight of dairy calves born of primiparae was lower than those of multiparae. But no significant difference in body weight gain was observable between dairy calves born of primiparae and those of multiparae. Body weight gain of diseased calves was lower than normal calves. Of 66 delivered calves, 34 calves(51.5%) were affected with gastronitestinal and/or respiratory diseases. The prevalence of the diseases were gastrointestinal disease(28.7%), respiratory disease(18.2%), and gastronitestinal and respiratory disease(4.6%). The gastronitestinal disease was occurred contrinually regardless of the season. Whereas all of the respiratory disease were occurred in winter and a change of season(December to April). 68.4% of the gastronitestinal disease, and all of the respiratory disease were occurred at atmospheric temperatures below 1$0^{\circ}C$. 89.5% of the gastronitestinal disease were occurred within 3 weeks old, whereas 50% of the respiratory disease were occurred intensively between 3 weeks and 4 weeks old. Of 66 delivered dairy claves, 2 calves were died(3%) with respriratory disease.

Purpose: This study was done to compare health risk behavior prevalence for youth living in metropolitan, medium sized and small cities or rural area, in order to enhance understanding regional differences. Methods: For this study, data from the 2006 Youth Health Risk Behavior Online Survey collected by the Korean Center for Disease Control were analyzed using SPSS. Results: In the metropolitan areas, prevalence for disease and perceived obesity were higher than in other areas. Lack of intense or moderate physical activity, obesity, fast food intake, and insufficient sleep showed higher prevalence than in rural areas. Prevalence of lifetime smoking, lifetime alcohol consumption, present alcohol use, fruit intake less than once a day, and not wearing a seat belt were higher in rural areas than in urban areas. Gender, smoking, and alcohol use were correlated. Spearman correlation between living with parent and skipping breakfast were significant. Smoking, alcohol use, and sexual behavior were correlated. Conclusion: As significant differences in prevalence of youth health risk behaviors exist between regional areas, health education and health promotion programs considering these differences have to be developed and implemented for adolescents. Programs for prevention of smoking and alcohol use, programs for improvement of fruit intake and safety are suggested for adolescents in rural areas, whereas programs to enhance physical activity and obesity management are suggested for adolescents in metropolitan areas.

Purpose: The purpose of this study was to explore prevalence and causal factors of musculoskeletal diseases on nurses. Methods: This study was an integrated review. Documentations were searched through electric databases using SAGE journals, EBSCOhost, Pubmed, RISS, NDSL and KCI. Terminology for this review was "Nurse" and "Musculoskeletal" and language versions were Korean or English. Number of final articles was 70 (Korean articles were 11 and english versions were 59). Results: Studies related to musculoskeletal diseases on nurses started in Sweden and USA from 1995. Subjects of studies were general hospital nurses in 50 out of 70 studies. Lower back in Korea and waist in other countries were highest areas of muculoskeletal disease's prevalence. Revisable factors of musculoskeletal diseases on nurses included physical, psychosocial and environmental factors that were more than unrevised factors. Conclusion: This study suggests to develop programs for preventing musculoskeletal disease of lower back or waist in general hospitals because of high frequency. Interventions to prevent musculoskeletal diseases need to consider prevalence and quality indicators on nurses.

Cardiovascular disease is very prevalent in Korea, and many risk factors, if properly identified are possibly corrected. However, the study results on prevalence and distribution of risk factors may not be reliable while the risk factors of disease are always issued on health promotion projects conducted recently in a community. The subjects of this study were 854 adults who participated in the health and nutrition survey in a community. They were aged between 20 and 69 and sampled representatively. This study intended to estimate the prevalence and the distribution of risk factors of cardiovascular disease such as hypertension, diabetes mellitus, hypercholesterolemia, and obesity. Systolic blood pressure and diastolic blood pressure levels were estimated at $123.9{\pm}2.2mgHg(men)$, $117.9{\pm}1.7mgHg$(women), and $80.4{\pm}1.5mg(men)$, $74.9{\pm}1.1mgHg(women)$, respectively. Glucose level was estimated at $99.1{\pm}2.3mg/dl$ in men, and $95.7{\pm}1.7mg/dl$ in women. The estimated level of total cholesterol and HDL-cholesterol were $183.4{\pm}3.8mg/dl(men)$, $181.7{\pm}3.1mg/dl(men)$, and $122.0{\pm}4.5mg/dl(women)$, and body mass index was estimated at $24.0{\pm}0.4kg/m^2$ in men and $23.9{\pm}0.4kg/m^2$ in men and $23.9{\pm}0.3kg/m^2$ in women. The prevalence of hypertension was 20.5% for men, and 14.4% for women. The prevalence of diabetes mellitus was estimated to 6.9% for men, and 6.1% for women. The estimated prevalence of hypercholesterolemia was 3.8%(men), 3.9%(women). The rate of obesity was estimated to 28.5%(men), 28.4% (women), respectively. The levels of blood pressure, glucose, and cholesterol were higher in men than in women in almost all the almost ate groups. The prevalence of hypertension for men is about 20%. It was found that the prevalence of diabetes mellitus for males aged between 40 and 59 was rapidly increased. The risk factor with highest prevalence was obesity, and hypertension and diabetes mellitus were the second and third most prevalent.

This study consisted of descriptive research to determine the prevalence of dry eye disease using the Ocular Surface Disease Index (OSDI) questionnaire targeting workers in hospitals to understand the differences between general and health related characteristics depending on whether people have dry eye disease, and to determine the influencing factors of the disease. The subjects were 502 (Male: 51, Female: 451) general hospital employees in G-city. The data were collected from October 1 to October 31, 2015. Logistic regression was used to analyze the data. The results showed that hospital workers' prevalence of dry eye disease was 76.1%. Factors influencing DED in this population included currently having or adjusting medication (OR: 4.73), among those who felt their eyes dry, those who visited clinics and received medical treatment (artificial tears) (OR: 2.37), those who felt eye dryness (OR: 2.23), and not eating regularly (OR: 0.55). Moreover, 54.0% of those who had dry eye disease reported serious conditions. Accordingly, education to manage the risk factors of the disease and improve lifestyle is needed to prevent and manage dry eye disease.

Cat scratch disease is a zoonotic disease usually caused by the gram-negative bacterium Bartonella henselae. It is transmitted commonly by scratch or bite from cats or kitten. Cat scratch disease typically affects children and young adults, who develop regional lymphadenopathy. In contrast, in immunocompromised hosts, bacteremia may occur, bacillary angiomatosis and bacillary peliosis hepatitis or splenitis are the most common manifestations. Bartonella henselae was detected in three of thirty veterinarians and Bartonella clarridgeiae was detected in one of thirty veterinarians by a novel nested polymerase chain reaction. Cat scratch disease will not be neglected, and it needs continuous studies as well as observation and prevention of this disease.

This study was performed to evaluate the relation between the interval of supportive periodontal therapy and the prevalence of the subgingival microflora. The subgingival plaques from 108 patients were used in the study. Control group were the patients with no periodontal treatment and test groups were assigned into 3 groups according to the period of recall check: group 1; 1-2 months, group 2; 3-4 months, group 3; 6months or more. The polymerase chain reaction (PCR) used for direct identification of periodontal pathogens (P. gingivalis, T. forsythensis, T. denticola) in subgingival plaque. The results of this study were as follows. 1. The prevalence of P. gingivalis, T. forsythensis, T. denticola in control group were 100%, 87%, 90%. 2. In clinical parameters such as plaque index, gingival index, bleeding on probing, control group was not significant different with group 1 but Significant different with group 2, group 3. 3. In group 1, the majority of P. gingivalis had type II fimA. 4. When group 3 were compared with group 1, the prevalence of P. gingivalis increased. But the prevalence of P. gingivalis with type II fimA, which have the virulence factor, decreased. 5. We were unable to find the correlation between P. gingivalis with type IV fimA and periodontal disease. 6. The prevalence of T. forsythensis, T. denticola in test group were 85%, 93% or more. From the above results, we were able to find the relation between the interval of supportive periodontal therapy and the prevalence of the subgingival microflora and the need of the strict supportive periodontal therapy to prevent recurrence of periodontal disease, because there were high prevalence of periodontal pathogens.

Purpose: Pineal gland calcification has been proposed to play a role in the pathogenesis of Alzheimer disease. This study evaluated the prevalence and extent of pineal gland calcification in cone-beam computed tomography (CBCT) scans of patients referred for dental implant therapy who could possibly be a vulnerable group for this condition. Materials and Methods: A retrospective evaluation of 500 CBCT scans was conducted. Scans that showed the area where the pineal gland was located were included. The scans were initially screened by a single observer to record the prevalence and extent of calcification. Six weeks following the completion of the study, another investigator randomly reviewed and selected 50 scans to investigate inter-observer variation, which was evaluated using reliability analysis statistics. The prevalence and measurements of the calcifications were reported using descriptive statistics. The chi-square test was used to compare the prevalence between males and females. Results: The prevalence of pineal gland calcification was 58.8%. There was no statistically significant correlation between age and the extent of the calcification. The prevalence of calcification was 58.6% in females and 59.0% in males. The average anteroposterior measurement was $3.73{\pm}1.63mm$, while the average mediolateral measurement was $3.47{\pm}1.31mm$. The average total calcified area was $9.79{\pm}7.59mm^2$. Conclusion: The prevalence of pineal gland calcification was high in patients undergoing implant therapy. While not all pineal gland calcifications lead to neurodegenerative disorders, they should be strongly considered in the presence of any symptoms as a reason to initiate further investigations.
