Objectives: The purpose of this study was to determine the relationship between methylation status of the Dact1 gene and MTHFR a1298c polymorphic forms in transitional cell carcinoma tissues in a Chinese population. Methods: Polymorphisms of folate metabolism enzyme gene MTHFR were assessed by restrictive fragment length polymorphism (RFLP) methods and PCR-based DNA methylation analysis was used to determine the CpG island methylation status of the Dact1 gene. Associations between the methylation status of the Dact1 gene and clinical characteristics, as well as MTHFR a1298c polymorphisms, were analyzed. Results: aberrant methylation of the Dact1 gene was found in 68.3% of cancer tissues and 12.4% of normal tissues,. The methylation rate of the Dact1 gene in cancer tissues was significantly higher in patients with lymph node metastasis than in those without lymph node metastasis (46.3% vs. 17.2%, P = 0.018). No association was found between aberrant DNA methylation and selected factors including sex, age, tobacco smoking, alcohol consumption and green tea consumption. After adjusting for potential confounding variables, variant allele of MTHFR a1298c was found to be associated with methylation of the Dact1 gene. Compared with wild type CC, the odds ratio was 4.33 (95% CI: 1.06-10.59) for AC and 4.95 (95% CI: 1.18-12.74) for AA. The N stage in TNM staging and the occurrence of lymph node metastasis were associated with an MTHFR 1298 AA+AC genotype (P<0.05). Conclusion: MTHFR 1298 AC and AA genotypes might help maintain a normal methylation status of the Dact1 gene, aberrant CpG island methylation of which is closely related to the genesis and progression of transitional cell carcinoma.

Purpose: This paper presented a descriptive study which aimed to identify the relationship among menstrual attitude, premenstrual distress and premenstrual coping in Korean college women and to propose fundamental data for the development of guidelines for effective management of premenstrual distress. Methods: The data were collected from 111 college women and analyzed using descriptive statistics, t-tests, ANOVA and Pearson's correlation coefficients. Results: The mean score of premenstrual coping was $3.25{\pm}0.60$ out of 5 points. The 'Awareness and Acceptance of Premenstrual Change' score was highest and the 'Avoiding Harm' score was lowest. Menstrual attitude was significantly related to premenstrual distress (r=.37 p<.001) and the awareness and acceptance style of premenstrual coping (r=-.21. p=.021). And premenstrual distress was significantly related to the self-care coping style of premenstrual coping (r=.30, p=.001), the adjusting energy coping style of premenstrual coping (r=.45, p<.001) and the avoiding harm coping style of premenstrual coping (r=.48, p<.001). Conclusion: Results of this study support that positive attitude about menstruation is necessary for the effective management of premenstrual distress. Also, premenstrual coping programs that consider the level of premenstrual distress will be needed for college women.

Objectives : This study was designed to discover the difference in stimulation effect when the volume and insertion method of mountain ginseng pharmacopuncture was varied. Methods : 48 healthy people were randomly injected with 0.1, 0.3, 0.5, and 0.7 cc of mountain ginseng pharmacopuncture, perpendicularly or transversely at acupoints $LI_9$ and $LI_{10}$. The subjects noted their level of stimulation on a 100 mm visual analog scale(VAS) immediately after, 3 minutes after, and 5 minutes after the treatment. Results : There was no significant statistical difference in the stimulation strength between perpendicular injection and transverse injection pharmacopuncture. There was significant statistical difference in the stimulation strength when the volume of pharmacopuncture was varied. As the volume of pharmacopuncture increased from 0.1 cc to 0.3 cc, and to 0.5 cc, the stimulation strength increased as well. Conclusions : We found that volume of pharmacopuncture may be a controlling element for mountain ginseng pharmacopuncture. Additional study is needed for pharmacopuncture's stimulation adjusting factors.

Purpose: The purpose of this study was to compare the levels of stress, social support, and marital satisfaction between married immigrant women living in urban areas and women living in rural areas to identify ways to improve their mental health. Methods: Two hundred married immigrant women were recruited from multicultural familysupport centers located in Daejeon City and Chungcheong Province. From July, 2009 to January, 2010, data were collected using self- administered questionnaire. Study instruments were scales for acculturative stress, housewives life stress, support from spouse, and marital satisfaction. Results: Urban married immigrant women had lower levels of acculturative stress and higher levels of support from spouse and more positive marital satisfaction compared to rural women. Both groups reported similar levels of stress in life as a housewife. Factors influencing marital satisfaction in both group were lower levels of acculturative and housewives life stress, higher levels of support from spouse, and living with parents-in-law. Conclusion: Rural married immigrant women may have more problems in adjusting to Korean culture and marriage compared to urban women. Therefore, to improve the physical and psychological wellbeing and marital adjustment of married immigrant women, development of nursing strategies according to area of residence is needed.

Objectives This study aimed to evaluate the risk factors associated with depression and suicidal ideation in a rural population. Methods A survey was conducted with 543 farmers from Chungcheongnam-do Province using the Center for Epidemiologic Studies Depression Scale (CES-D) for depression, Lubben Social Network Scale (LSNS) for social support, Swedish Q16 for neurotoxicity symptoms and a survey tool for farmer's syndrome. Results After adjusting for socioeconomic factors using logistic regression analysis, poor self-rated health, low social support and neurotoxicity were positively associated with the risk of depression (odds ratio [OR], 15.96; 95% confidence interval [CI], 3.11 to 81.97; OR, 3.14; 95% CI, 1.26 to 7.82; and OR, 3.68; 95% CI, 1.08 to 12.57, respectively). The risk of suicidal ideation significantly increased with low social support, neurotoxicity and farmer's syndrome (OR, 2.28; 95% CI, 1.18 to 4.40; OR, 6.17; 95% CI, 2.85 to 13.34; and OR, 3.70; 95% CI, 1.51 to 9.07, respectively). Conclusions Given the overall results of this study, there is a need to establish programs which can improve the health and social relationships of farmers. Also, when farmers have neurological symptoms from pesticide exposure and characteristic symptoms of farmer's syndrome, a monitoring system for depression and suicide must be made available.

New materials are very useful due to their wide range of applications, however, they also have caused new pollutants that damage our environment. Chemists have been conscious of the severity of these environmental problems and a great deal of effort has been put into developing environmentally benign chemical processes to synthesize new materials (green synthesis). We also have reported a green synthesis method of synthesizing silver nanoparticles using water-glycerol solution in a previous study. While conducting further research, we have recently discovered that the size of silver nanoparticles is proportional to the quantity of water present in glycerol. This method is completely benign and ecofriendly pathway, as the size of silver nanoparticles is adjusted solely by controlling the quantity of water added to glycerol, without extra additives and energy.
