To examine the changes in resistance to benomyl of Fusarium species causing bakanae disease, Fusarium isolates were collected in Korea, and pathogenicity tests were performed using rice seeds in vitro. Minimum inhibitory concentration (MIC) and effective concentration of 50% ($EC_{50}$) values of isolates were examined using the agar dilution method. High frequency distribution of MIC values to benomyl against isolates collected in 2006~2007 and 2013~2014 years were $1.5625{\sim}3.125{\mu}g/mL$ and more than $25{\mu}g/mL$, respectively. The mean $EC_{50}$ value of isolates to benomyl increased from $1.6397{\mu}g/mL$ in 2006~2007 to $2.4892{\mu}g/mL$ in 2013~2014. Based on MIC and $EC_{50}$ values of isolates, the moderate resistance of benomyl were determined as more than $25{\mu}g/mL$ of MIC and less $2.4{\mu}g/mL$ of $EC_{50}$ value, and resistant isolates to benomyl were determined as more than $2.4{\mu}g/mL$ of $EC_{50}$ value. Compared with the ratio of resistant isolates in 2006~2007, the ratio of resistance isolates in 2013~2014 increased from 12.5% to 36.4%. In addition, multiple resistant isolates to prochloraz as well as benomyl increased to 20.3% in 2013~2014.

This study was conducted to reveal the relationship between the oral health status and their Knowledges about the oral health of the freshman of colleges in Taegu city. The evaluation for the oral health status through the oral examinations and their analysis of their knowledges on the periodontal disease were done on 216 males and 205 females from 1st to 30th April, 1993. The obtained results were as follows: The oral health status of 421 subject showed that 35.7% was good, 59.1% fair, and 6.2% poor, respectively. In case of the oral health status of females, 41.9% was good and 4.4% poor, and then in males 27.8% was good, 7.8% poor. The oral health status of the females was better than that of the males(p=0.006). The 52.1% among the good oral health status group answered that the dental plaque is the bacterial membrane causing dental disease, and the 23.1% among the poor oral health status group answered same as the above. The 91.8% among the good oral health status group answered that the periodontal diseases can be prevented, and the same answer came out from 15.4% of the poor group. It was found that the better oral health status group had the better knowledges about periodontal disease(p=0.001). For the question about their experiences in scaling the 30.1% of good oral health status group and the 23.1% of poor group answered that scaling is very helpful to periodontal health(p=0.001). About the experience of the education for tooth brushing, the 53.2% of good oral health status group and the 7.6% of poor group had the experiences to receive the education for tooth brushing(p=0.001). About the frequency and the time of tooth brushing, the 53.4% of good oral health status group brushed their teeth more then 3 times a day and 41.8% of good group brushed their teeth after every meal(p=0.001). The result of multiple regression analysis according to the simplified oral health index indicated that the variable having an effect on the oral health status was the tooth brushing frequency, knowledge of periodontal disease prevention, experience in education of tooth brushing and time of tooth brushing(p=0.001).
In this study, we analyzed situation and length of stay(LOS) variations of inpatients with pressure ulcer using patient safety indicators developed by the United States Agency for Healthcare Research and Quality(AHRQ) and proposed management of medical quality and development of policy. The dataset was taken from 1,373 database of the hospital discharge injury survey from 2005 to 2008. Analysis method was used frequency and chi-square test, ANOVA, multiple linear regression analysis. In result, distribution of inpatients with pressure ulcer by sex were 52.5%(male), 47.5%(female), respectively and aged $65{\geqq}years$ was the highest in age group. LOS of inpatients with nervous system principal disease was the longest. Independent variables which were statistically associated with LOS of inpatients with pressure ulcer were year, sex, insurance type, bed size, operation, principal diagnosis. Therefore, hospital should develop the standardized strategy and guidelines to manage pressure ulcer inpatients efficiently and apply it into the medical information system.

Background: Due to the rapid progress of industrialization, the expansion of the nuclear family, and an increase in women's social activities, the burden of care of cancer patients has increased, so that all family members are now involved in care. We compared the health-related quality of life (HRQOL) between members of families of cancer patients (hereafter, cancer families) and members of cancer-free families (non-cancer families). Materials and Methods: The data were from the Community Health Survey (2012). The study population included respondents at least 30 years of age. Data were adjusted for the following covariates: sex, age, education, marital status, household income, economic activity, household type, chronic disease, and perceived health status. Frequency analysis, analyses of variance, and multiple linear regression analysis were performed. Results: Among 163,495 respondents, 3,406 (2.1%) were part of a cancer family and 160,089 (97.9%) were part of a non-cancer family. Cancer families had lower EQ-5D scores than non-cancer families. However, by subgroup, the scores had significant association between cancer and non-cancer families only for females and for those who worked. Conclusions: There was a significant relationship between HRQOL scores and being a family member of a cancer patient. This indicates that the responsibility for care has been extended to the entire family, not only the primary caregiver.

Objectives: The purpose of this study was to assess excavator drivers in order to determine the proportion showing subjective symptoms of musculoskeletal disorders and to evaluate the association between the symptoms and characteristics of the subjects. Methods: A questionnaire survey was conducted to collect the information on participants' age, average working hours per day, duration of career (years), work-related musculoskeletal symptoms, and more. The final dataset included 141 excavator drivers. Frequency and percentage were summarized and then the associations between the characteristics of the subjects and symptoms were evaluated as odds ratios (ORs) and 95% confidence intervals (CIs) using multiple logistic regression analysis. Results: Seventy-six percent of the currently reported musculoskeletal symptoms. Those who have musculoskeletal symptoms attributed their symptoms to unstable posture at work, mental stress or vibrations. There was a significant association between symptoms of musculoskeletal disorders and career of excavator drivers (P for trend=0.04). Conclusions: The results of this study suggest that the prevalence of musculoskeletal disorders may be high among excavator drivers and warrants well-designed studies on work-related disorders among excavator drivers.
Purpose: The purposes of this study were to investigate factors related to the depression of the elderly dwelling in a big city, and to explore the influence of physical health, cognitive symptom and nutritional status on the elders' depression. Methods: After the approval of the Institutional Review Board (IRB) and obtaining the participants' consent form, a face to face and private interview was conducted with each participant from Mar, 2007 to Aug, 2007 by trained graduate level students. A total of 201 elders aged over 65 years participated in the study. The questionnaire consisted of K GDS, PHQ 15 and Nutritional Screening Initiative (NSI). Collected data were analyzed with the SPSS 13.0 program, which was used for frequency, percentage, mean, standard deviation, Pearson correlation coefficients, and multiple regression. Results: The major findings of this study were as follows. 1) 28.4% of the subjects belonged to the depression group, 78.1% had one or more diseases, 85.6% had experienced somatic symptoms, and 49.7% belonged to the nutritional risk group. 2) Older age, lower educational level, more pocket money a larger number of diseases, more severe cognitive symptoms and poorer nutritional status were significantly related to a higher depression score. 3) Significant factors influencing depression were nutritional status, cognitive symptoms and the number of diseases, which explained 38.1% of the variance of elderly depression, and nutritional status was the most influencing factor. Conclusion: The finding of this study gives useful information for developing assessment tools and interventions for elders' depression.
Objectives : This study aimed to analyze the characteristics of uninsured herbal medicine(UHM) users and the economic and social barriers of UHM utilization. Methods : We used the Korea Health Panel Data, representative national survey on medical utilization and cost, provided by National Health Insurance Service and Korea Institiute of Health and Social Affairs. The frequency analysis was used to identify the characteristics of the respondents, and the cross-analysis (${\chi}^2-test$) was used to verify the relationship between their characteristics and the usage of UHM. In order to analyze the determinants of using the UHM considering the individual's characteristics, logistic regression analysis and multiple regression analysis were conducted for those who used the Korean medicine (KM) outpatient service in 2015. Results : The usage of UHM was significantly lower for those (1) who's age of 20 to 65; (2) who have the university or higher education degree; (3) who live in Jeju province, and (4) who bought the herbal medicine for other health related purposes. On the other hand, the usage of UHM for those (1) who have the first quintile of household income; (2) who have the chronic respiratory disease; (3) who have been taking the medicine for health promotion purpose for more than 3 months and (4) who have purchased the food which has health promotion function was significantly higher than others. The patients who have chronic musculoskeletal diseases accounted the most among the UHM users. Conclusions : There was the considerable inequality in the usage of UHM among household income groups, which provides policy rationale for UHM to be covered by national health insurance. To facilitate the coverage expansion, restrictive covering model can be considered for children and adolescents, or for patients with muskuloskeletal diseases who have the high demand for UHM.
