Survey on plant diseases occurring on cucumber cultivated in plastic film house of experimental farm in Suwon was conducted. Through the survey, occurrence of damping-off, downey mildew, powdery mildew and Fusarium wilt was observed. Especially downey mildew caused by Pseudoperonospora cubensis was the most severe foliar disease of cucumber. To control the disease effectively, effects of installation of ventilation fan and optimal spray timing of a chemical, dimethomorph+copper oxychloride WP, were investigated. Two ventilation fans installed at the front and at the back of plastic film house reduced air relative humidity by about 6.4% and downey mildew incidence by 55.7%. Downey mildew incidence on cucumber from untreated chemicals plot in plastic film house installed with ventilation fan was on a equal level with that from treated chemicals plot with three times application of dimethomorph+copper oxychloride WP in plastic film house without ventilation fan. Meanwhile in order to select optimal chemical application time, dimethomorth+copper oxychloride WP was treated three times at 7 days-interval from three days before the disease occurred, right after the disease occurred, and two days after the disease occurred, respectively. The result showed that dimethomorth+copper oxychloride WP applied to cucumber leaves and stems from three days prior to, right after, two days after occurrence of downey mildew reduced downey mildew incidence by 72.9, 61.8, and 23.7%, respectively. The above results showed that regulation of environmental factors like air relative humidity and preventive application of chemicals should be considered to establish control strategy to downey mildew.

Objective: This study was conducted in order to investigate the effects of individual patient behavior regarding the health and medical care level on their therapeutic compliance for people diagnosed with high blood pressure by a physician, in order to evaluate the impact of treatment compliance. In this study, the therapeutic compliance was defined as the hypertension drug cure rate. The current blood pressure controls were persons about 30 years of age diagnosed with high blood pressure by their doctor one month fraction of the people who take more than 20 days (30 days). Methods: The data was analyzed by using the X2-test for different comparisons of the therapeutic compliance in the individual characteristics and using a two-stage multilevel logistic regression to identify the community variance of the related index of high blood pressure therapeutic compliance using the data from 229 adults over the age of 19 in a community health survey conducted in 2010. The Spss 18.0 statistical program was used with HLM 7 (hierarchical linear model) Results: It was found that the rate of therapeutic compliance was affected by the individual health behavior and health and medical care levels. Conclusion: In this study, although the odds ratio of the variable region of the high level of health care, I was able Unlike previous studies and focuses on the personal level of variation found variations in the local health care level was a significant. More studies on multilevel analysis are needed in the future considering regional level data.

The purpose of this study was to investigated the effects of alcohol intake on blood pressure, serum lipids, liver function tests and obesity indices in middle-aged male workers. The 2,175 male workers aged 30-59 years who examined health checkup were recruited as the study subjects during the period between January to December, 2013. We observed the relationships between the amount of alcohol intake and blood pressure, serum lipids, liver function tests and obesity indices. As a result, the mean score of SBP, DBP, LDL-C and TG were significantly higher increasing with amount of alcohol increased, but HDL-C were significantly lower increasing with amount of alcohol increased. AST, ALT, ALP and ${\gamma}$-GTP were significantly higher increasing with amount of alcohol increased, but obesity indices were not significant. Age adjusted odds ratios(ORs) increasing with abnormal levels of SBP, DBP, HDL-C, LDL-C, TG, AST and ALT were significantly increased in heavy drinking group than light drinking group. Above results suggested that the heavy drink related with blood, serum lipid levels and liver function test levels, but not find out with obesity indices.

The aim of this study was to help disease management and prevention by analyzing the effects of income and education levels on the health of cardio-cerebrovascular patients. Using the raw data of 2010-2011 Korea Health & Nutrition Examination Survey, the correlations of health behaviors, general (socio-demographic) characteristics, body measurements, and blood test results of 3,687 cardio-cerebrovascular patients aged 30 or older were analyzed based on their income and education levels. The results suggested that lower income and education levels were correlated with a high prevalence of cardio-cerebrovascular diseases. In addition, the OR values (95% CI) of current smoking were 0.71 (0.52-0.96) for patients with a high-income and 0.41 (0.29-0.58) for those with a high level of education, showing a strong correlation between lower levels of income and education and current smoking, which is related to health deterioration. In terms of one-month drinking and high risk drinking, the OR values (95% CI) of the patients with a high income were 1.55(1.22-1.95) and 1.42(1.11-1.82), respectively. Drinking was more prevalent among high-income patients but had no correlation with the education level. The practice of walking had no significant correlation with both income and education levels. Therefore, it is imperative to emphasize the importance of temperance to high-income patients, and the importance of quitting smoking to low-income patients, as well as to provide institutional support.

This study was conducted to analyse climate change impact on agriculture infrastructure and propose improved measures on vulnerable areas. Recently, Climate change has resulted in damaging effects on agricultural fields through increases in drought intensity and flood risk. It is expected that this impact will increase over time. This study shows that Gyeong-gi and Chung-nam provinces are affected by drought and Gyeong-buk and Gyeong-nam provinces are affected by heavy rain. However, there are also regional variations within each province. Agricultural infrastructure affected by drought may also be affected by heavy rain. Increased damages on the infrastructure due to increased extreme weather events require preventive measures especially in vulnerable areas. In order to minimize the damage by climate change, we need to introduce a reform in the system which selects project region by analysing climate change impacts. Furthermore, impact assessment of climate change from projects such as 'water supply diversification', 'flooded farmland improvement', and 'irrigation facility reinforcement' also need to be adopted to improve the measures. The results of this study are expected to provide a foundation for establishing measures on coping with climate change in the agricultural sector.

$O^6-methylguanine-DNA$ methyltransferase (MGMT) is a DNA repair protein that protects cells against the carcinogenic effects of alkylating agents. The loss of MGMT expression was commonly known due to hypermethylation of CpG islands in its promoter region. We evaluated the expression of MGMT by immunohistochemistry in order to examine the relationship between loss of MGMT expression and clinicopathological characteristics in 74 Korean patients with non-small cell lung cancers. Loss of MGMT was detected in 25 (33.8%) of 74 cases. The loss of MGMT expression was frequently seen in the adenocarcinoma than in the squamous cell carcinoma (p=0.021). However, there was no significant differences between loss of MGMT expression and other clinicopathological characteristics, including age, gender, smoking status, tumor size, tumor T stage, and lymph node metastasis (p>0.05). In conclusion, loss of MGMT expression was related with the histologic type of lung cancer. Further methylation study of MGMT promoter is needed to evaluate the relationships with immunohistochemical expression of MGMT and to clarify the role of MGMT in lung cancer.

In order to investigate the cellular peroxidative damage due to heated oil intake and the preventive effect of vitamin E on it rats were fed heated corn oil with acid value of 4.02 at the level of 10 Cal% and three different levels of vitamin E that were 0, 40 and 200 mg/kg diet. Control group was fed fresh corn oil and 40mg/kg diet of vitamin E. After ech feeding period of 0, 3 and 6 weeks, liver superoxide dismutase (SOD), glutathione peroxidase (GPX) activities and microsomal content of vitamin E and lipid peroxide (LPO) were measured as well as cellular morphology was examined. SOD activities and LPO contents were higher, while GPX activities and vitamin e contents were lower in heated oil groups than control group. Electromicroscopic observation revealed the loss of inner mitochondrial membrane and cristae and irregular arrangement of nuclear membrane and chromatin in heated oil groups. As dietary vitamin e level was increased, SOD activity and LPO content were decreased, but GPX activity and vitamin E content in the liver increased and cellular peroxidative damage reduced progressively. This phenomena was more remarkable in 6 weeks of feeding than 3 weeks.

The purpose of this study is to 1) investigate the prevalence rate of the abuse of parents by their teenage children and the effect of child abuse on parent abuse, 2) examine moderating effect of positive friend relationships on violence toward parents, and 3) provide the implication to the adolescent-to-parent abuse. In order to accomplish these purposes, a total of 1,601 who are middle and high school students in Seoul and Gyeonggi province were utilized. Data were analyzed by frequency analysis, and Poisson regression model analysis with SPSS 21.0. The main results of this study are as follows. Frist, prevalence of parent abuse were 12.8%. Second, 40.6% of adolescents have childhood experience of abuse, and this experience has significant relationships with perpetrating behavior toward parents. Lastly, adolescents' positive relationships with friends play an important role in moderating parent abuse. These findings suggest that there is a strong need to formulate the multilateral approaching system to the parent who are victims of abuse and perpetrating adolescents in order to understand the characteristics adolescent-to-parent violence problems and intervene effectively in diverse systems. Political and practical implications on parent abuse preventive programs and coping strategies are discussed.
