Purpose: This study was descriptive survey research to examine the factors affecting menopause, depression and menopausal symptoms, and the relations among these factors in South Korean midlife women. Methods: The subjects were 319 midlife women in Daegu City. Measures were Zung's Self-Report Depression Scale (1979) to check depression, and the Midlife Women's Symptom Index developed by Im (2006) to check menopausal symptoms. Data were collected from June 1 to July 31, 2010. Collected data were analyzed by mean, standard deviation, and Pearson's correlation coefficient through SPSS/WIN 18.0. Results: There was a statistically significant correlation between depression and menopausal symptoms (r=.692, p<.001). The factors affecting depression were age (r=.194, p<.001), income (r=-.307, p<.001), exercise (r=-.602, p<.001), and menopausal status (r=.224, p<.001). The factors affecting menopausal symptoms were exercise (r=-.158, p<.037), menstrual pain (r=-.171, p = .004) and menopausal status (r=.222, p<.001). Conclusion: Intervention programs for decreasing menopausal symptoms in midlife women should be focused on relieving menopausal pain and encouraging excise from youth. Further studies will be needed to examine the relations among other factors including living style, area and menopausal symptoms.

Purpose: The objective of this study was to estimate the radiation absorbed doses in certain critical organs in the head and neck region with 16 imaging programs available on the Orthopos/sup (R)/ panoramic machine. Materials and Methods: A Rando phantom and LiF TLD chips were used for dosimetry. The absorbed doses were measured at the thyroid gland, the submandibular gland, the parotid gland, the mouth floor. the maxillary sinus, the brain, the mandibular body, the mandibular ramus. the 2nd cervical spine and the skin over TMJ area. Results : The overall absorbed doses with imaging programs available on the Orthopos/sup (R)/ panoramic machine were much less than that of standard program (program 1) except program 8, 11, and 16. Generally, the absorbed doses to the bone marrow of the mandibular ramus and the parotid gland were high, but the absorbed doses to the bone marrow in the mandibular body, brain, maxillary sinus, and, especially, the thyroid gland were very low. Conclusion : The modified imaging programs available on the Orthopos/sup (R)/ panoramic machine can be effectively used in aspect of radiation protection.

Bacterial diversity and the composition of individual communities during the composting process of swine and mushroom cultural wastes in a field-scale composter (Hazaka system) were examined using a PCR-based approach. The composting process was divided into six stages based on recorded temperature changes. Phylogenetic analysis of eighty 16S rRNA sequences from uncultured composting bacterial groups revealed the presence of representatives from three divisions, including plant pathogenic bacteria, high-molecule-degrading bacteria and spore-forming bacteria. The plant pathogen A. tumefaciens gradually decreased in abundance during the composting process and eventually disappeared during the thermophilic and cooling stage. A bacterium homologous to Bacillus humi first appeared at the early thermophilic stage and was established at the intermediate thermophilic, post-thermophilic, and cooling stages. It was not possible to isolate the B. humi during any of the stages using general culture techniques.

Paramyosin is a myofibrillar protein present in helminth parasites and plays multifunctional roles in host-parasite interactions. In this study, we identified the gene encoding paramyosin of Clonorchis sinensis (CsPmy) and characterized biochemical and immunological properties of its recombinant protein. CsPmy showed a high level of sequence identity with paramyosin from other helminth parasites. Recombinant CsPmy (rCsPmy) expressed in bacteria had an approximate molecular weight of 100 kDa and bound both human collagen and complement 9. The protein was constitutively expressed in various developmental stages of the parasite. Imunofluorescence analysis revealed that CsPmy was mainly localized in the tegument, subtegumental muscles, and the muscle layer surrounding the intestine of the parasite. The rCsPmy showed high levels of positive reactions (74.6%, 56/75) against sera from patients with clonorchiasis. Immunization of experimental rats with rCsPmy evoked high levels of IgG production. These results collectively suggest that CsPmy is a multifunctional protein that not only contributes to the muscle layer structure but also to non-muscular functions in host-parasite interactions. Successful induction of host IgG production also suggests that CsPmy can be applied as a diagnostic antigen and/or vaccine candidate for clonorchiasis.

Purpose: The purpose of this study was to investigate the correlation of sexual satisfaction and daily stress in breast cancer patients. Methods: Data was collected through self-administered questionnaires and analyzed by descriptive statistics, t-test, ANOVA and Pearson's correlation. Data survey was conducted with 500 conveniently selected breast cancer patients who visited the out patient department in 5 university hospitals in Seoul, Gyung-gi and Gang-won province. Results: The sexual satisfaction of breast cancer patients score was 31.34 and there were significant sexual satisfaction differences by age, education level, menopause and sexual activity frequency. Sexual satisfaction was negatively related with daily stress (r = -.177) especially personal stress (r = -.155), economic stress (r = -.138), stress of self (r = -.181), family stress (r = -.154) and stress about leisure (r = -.139). Conclusion: These findings are expected to make a contribution to creation of ideal sexual rehabilitation nursing interventions for breast cancer patients care nurse. Furthermore continuous and customized education and counseling programs can contribute to promote healthy sexual life for breast cancer patients.

Purpose: This study were to investigate BMD of middle-aged women and to examine the relationships between BMD and Physical, Obstetric characteristics Method: The data was collected from 119 healthy women who were 40-60 years old. they were examined for BMD at 4 regions(forearm, lumbar, femur, whole body), %fat by DEXA and investigated physical, obstetric characteristics using scale, questionnaire from January to March, 2001. Result: 1) According to bone diagnostic results by WHO classification, 95.8% of forearm and whole body BMD were normal but 21.8-48.7% of lumbar and femur BMD(neck, trochanter, ward's triangle) were diagnosed osteoporosis or osteopnea. 2) The bones were significantly positive correlations of each other (r=.19-.69, p=.04-.00) and there were significant correlations between BMD and physical, obstetric characteristics such as age (r=-.22, p=.02), weight(r=.36~.48, p=.00), height(r=.22, p=.02), %fat(r=.19, p=.04) and age of first delivery(r=-.28, p=.00). Conclusion: Based on this study, healthy middle-aged women were also exposed to risk of osteoporosis related to aging, change of physical conditions or hormonal release. Further research to develop nursing interventions for the purpose of preventing osteoporosis by modifying risk factors is suggested.

The effects of Lavandula angustifolia extract fermented with Pediococcus pentosaceus DK1 on UVB-mediated MMP-1 expression and collagen decrease in human skin fibroblasts were determined, and the conversion of its components was also analyzed. Fermentation was performed at varying L. angustifolia extract and MRS medium concentrations, and optimal fermentation conditions were selected. L. angustifolia extracts showed decreased cytotoxicity after fermentation in the fibroblasts. UVB-irradiated fibroblasts treated with fermented L. angustifolia extract showed MMP-1 expression 8.2-14.0% lower than that in UVB-irradiated fibroblasts treated with non-fermented extract. This was observed even at fermented extract concentrations lower than those of non-fermented extracts. Fibroblasts treated with fermented L. angustifolia extract showed 20% less reduction in collagen production upon UVB irradiation than those treated with non-fermented extracts. UVB-irradiated fibroblasts treated with fermented L. angustifolia extracts showed 50% higher inhibition of ROS generation than those treated with non-fermented extract. Luteolin and apigenin glycosides of L. angustifolia were converted during fermentation, and identified using RP-HPLC and LC/ESI-MS. Therefore, the effects of L. angustifolia extract on MMP-1 expression and collagen decrease in UVB-irradiated human skin fibroblasts were increased through fermentation by P. pentosaceus.

This study was carried out for the molecular level identification of recombinant protein vaccine efficacy, by oral feeding against white spot syndrome virus infection, with the comparison of viral mRNA transcriptional levels in shrimp cells. For the determination of WSSV dilution ratio for the vaccination experiment by oral feeding, in vivo virus titration was carried out using different virus dilutions of virus stock ($1{\times}10^2$, $2{\times}10^2$, and $1{\times}10^3$). Among the dilution ratios, $2{\times}10^2$ diluted WSSV stock was chosen as the optimal condition because this dilution showed 90% mortality at 10 days after virus injection. Recombinant viral proteins, rVP19 and rVP28, produced as protein vaccines were delivered in shrimps by oral feeding. The cumulative mortalities of the shrimps vaccinated with rVP19 and rVP28 at 21 days after the challenge with WSSV were 66.7% and 41.7%, respectively. This indicates that rVP28 showed a better protective effect against WSSV in shrimp than rVP19. Through the comparison of mRNA transcriptional levels of viral genes from collected shrimp organ samples, it was confirmed that viral gene transcriptions of vaccinated shrimps were delayed for 4~10 days compared with those of unvaccinated shrimps. Protection from WSSV infection in shrimp by the vaccination with recombinant viral proteins could be accomplished by the prevention of entry of WSSV due to the shrimp immune system activated by recombinant protein vaccines.
