Purpose: We analyzed climacteric symptoms, bone mineral density (BMD), serum estradiol ($E_2$) and follicle stimulating hormone (FSH) to identify the health benefits of meridian massage in perimenopausal women. Methods: There were 16 women in the experimental group and 17 people in the control group. Meridian massage was performed for 4 weeks, 3 times a week for 20 minutes each session. The data were collected pre-treatment, posttreatment and 4 weeks after treatment. SPSS/WIN 11.5 was used for data analysis. Results: After meridian massage, there were significant differences in climacteric symptoms (U = 65.50, p = .011) and BMD (U = 65.50, p = .011) between the two groups. The E2 level showed a significant difference between the two groups pre- and posttreatment (U = 75.00, p = .028). FSH showed a significant increase when measured at 4 weeks after the treatment as compared with the amount when measured post-treatment within the control group (z = -2.249, p = .025), experimental group showed a stable change in FSH. but there was no significant difference between the groups. Conclusion: In this study, we confirmed the effects of Meridian massage in decreasing climacteric symptoms, inhibiting the decrease of BMD and stabilizing serum hormone in perimenopausal women. Therefore, it can be considered for use as a nursing intervention for health management in perimenopausal women.

In this study, meridian massage is developed and applied on post menopausal Women with Hemodialysis to identify the effects of Menopausal Symptoms, Mood, Estradiol($E_2$), and Pain. The study was a nonequivalent control group pre-post test Quasi-experimental design. There were 17 people in the experimental group and 17 people in the control group. Meridian massage was performed for 4 weeks, 3 times a week for 20 minutes each sessions. The data were collected at pretest and posttest. SPSS win. 11.5 program was used. Fisher's exact test and Mann Whitney U-test were used to analyze the Pre-treatment homogeneity. Wilcoxon Sign Rank test was used to find out the effectiveness within each groups. Mann Whitney U-test was used in comparing between the two groups. After meridian massage, there were significant differences in menopausal symptoms in experimental group(z=-2.583, p=.010) and pain between groups(U=86.00, p=.040). $E_2$ was not effective in both groups. The mood was effective in both groups, since the mood had influenced by interviewer's collecting data. Meridian massage was effective in alleviating menopausal symptoms and pain of post menopausal women with Hemodialysis, but it is desirable to perform meridian massage to the patients for enough time.

The existing vision-based techniques for inspection and condition assessment of civil infrastructure are mostly manual and consequently time-consuming, expensive, subjective, and risky. As a viable alternative, researchers in the past resorted to deep learning-based autonomous damage detection algorithms for expedited post-disaster reconnaissance of structures. Although a number of automatic damage detection algorithms have been proposed, the scarcity of labeled training data remains a major concern. To address this issue, this study proposed a semi-supervised learning (SSL) framework based on consistency regularization and cross-supervision. Image data from post-earthquake reconnaissance, that contains cracks, spalling, and exposed rebars are used to evaluate the proposed solution. Experiments are carried out under different data partition protocols, and it is shown that the proposed SSL method can make use of unlabeled images to enhance the segmentation performance when limited amount of ground truth labels are provided. This study also proposes DeepLab-AASPP and modified versions of U-Net++ based on channel-wise attention mechanism to better segment the components and damage areas from images of reinforced concrete buildings. The channel-wise attention mechanism can effectively improve the performance of the network by dynamically scaling the feature maps so that the networks can focus on more informative feature maps in the concatenation layer. The proposed DeepLab-AASPP achieves the best performance on component segmentation and damage state segmentation tasks with mIoU scores of 0.9850 and 0.7032, respectively. For crack, spalling, and rebar segmentation tasks, modified U-Net++ obtains the best performance with Igou scores (excluding the background pixels) of 0.5449, 0.9375, and 0.5018, respectively. The proposed architectures win the second place in IC-SHM2021 competition in all five tasks of Project 2.

The economy of the EU left behind the U. S. economy in many different aspects and the gap is widening. One major reason that promoted the EU's leading position is the ability to continuously advancing industrial technology and therefor secures the EU's leading position through a high level of competitiveness. The role as a powerhouse of the technological development is nurtured by a systematic attempt of the EU commission to stimulate international cooperation. Although the EU is focussing its efforts on international cooperation between EU members states, nonmembers, namely Korea, can benefit from this policy as well and generate win-win outcomes for both cooperating partners. The paper aims in the first chapter to introduce international technological cooperations in general. The second chapter identifies the political approach of both countries towards technological cooperations. The third chapter introduces the research method. In the forth chapter is analyzed a case study of two cooperation projects between Japan and the EU. Finally, implications for Korean policy makers are given.

The purpose of this study is to make formulated examination and analysis about major two factors of dental hygienic students' satisfaction at clinical training, i.e. the contents of clinical training and their duties satisfaction, so that it can provide a basic reference material for more efficient clinical training and education. This study conducted a questionnaire survey for 427 students who were taken via simple random sampling from sophomore and junior dental hygienic students, who already experienced in clinical training courses, at some universities(and colleges) in Metropolitan and province areas. The data collected from this survey were analyzed using SPSS WIN 11.5, in parallel with t-test, one-way ANOVA and ${\chi}^2$(Chi-square) test. It was found that our students didn't feel so much satisfied at clinical training(satisfaction level = 3.34). Overall, they didn't show any significant satisfaction with the contents of training and the experiences in clinical training duties. Our dental hygiene students showed relatively low satisfaction with the contents of clinical training as well as satisfaction at clinical training duties, which ie that current clinical training in dental hygienics still remain at the level of simple assistance for dental treatment.
