압축공기를 활용한 가스터빈 발전방식(CAES-G/T)은 태양열이나 풍력과 같은 신재생 에너지의 출력 변동성을 조절하는 유력한 수단 중 하나로 고려되고 있다. 국내에서 CAES 발전이 실용화된다면 지질여건상 암반터널식이 채택될 가능성이 크다. 암반터널식 CAES 시설에서는 압축공기 저장공간을 밀폐시키기 위한 콘크리트 플러그의 설치가 필요하므로 플러그의 형상과 크기를 결정하는 것이 중요한 설계변수가 된다. 파괴에 대한 안전율 분포와 접촉부 접촉압력 분포 분석을 통해 2가지 형태의 콘크리트 플러그에 대한 안정성 평가를 수행하였다. 주어진 지질조건에서는 테이퍼형 플러그가 쐐기형 플러그에 비해 구조적으로 안정한 것으로 나타났다. 쐐기형 플러그의 경우 측면 접촉부에서 분리현상이 예측되었고 이러한 분리면에서 압축공기의 누출 가능성과 마찰저항의 감소가 발생할 수 있음을 보여주었다.

To evaluate the effectiveness of acupuncture treatment for shoulder impingement syndrome (SIS) a literature review was conducted of randomized controlled trials (RCTs) where acupuncture was used as an intervention for patients diagnosed with SIS. Relevant clinical studies (N = 181) were retrieved from several databases based on the inclusion/exclusion criteria, and the interventions and results were analyzed. Six RCTs were selected to review based on the inclusion and exclusion criteria. In all 6 studies, the acupuncture treatment group showed significant positive changes in indicators evaluating pain, disability, and quality of life. A significant decrease in the evaluation indicators (Shoulder Pain and Disability Index, numeric rating scale, Visual Analogue Scale, Constant Murley Shoulder Assessment Score, patient's global assessment, and doctor's global assessment) and a significant increase in the questionnaire scores (UCLA, AL-score, EuroQol 5 Dimension Self-Report Questionnaire, and disabilities of the arm, shoulder, and hand) were observed. In addition, 1 study showed similar improvements in pain and quality of life measures in the acupuncture group and corticosteroid injection group. No major side effects were reported. Acupuncture may be an effective and safe treatment for SIS however, further RCTs are required.

Echocardiography is one of the most useful diagnostic techniques for differentiating heart disease as well as mitral valve lesion. Forty client-owned small breed dogs (weight, 2.3-13.2 kg) aged between 8-17 years with myxomatous mitral valve degeneration (MMVD) were included in the present study. The diagnosis of MMVD in dogs was made based on the clinical signs, chest radiography data, and echocardiographic findings. Echocardiographic examinations were conducted in accordance with recommended standards for dogs. M-mode, Doppler, and 2D echocardiography were performed in left and right lateral recumbency. 2D echocardiography was used to measure LA and Ao diameter from 2D short axis at the level of the aortic valve. In the comparison of conventional echocardiography indices in dogs with different stages of heart failure with MMVD, significant differences were observed in E/A ratio (p=0.005), EDV (p<0.001), EDVI (p<0.001), E-peak velocity (p= 0.001), ESV (p=0.028), ESVI (p=0.004), LA (p<0.001), LA/Ao Ratio (p<0.001), LVIDd (p<0.001), LVIDd/Ao Ratio (p<0.001), LVIDs (p=0.036), LVIDs/Ao Ratio (p=0.002), and MR Velocity (p=0.026). In addition, distinct correlations were found in EDV (r=0.712), LA/Ao ration (r=0.830), LVIDd (r=0.724), and LVIDd/Ao ratio (r=0.759). This study found that known conventional echocardiographic indices, including EDV, LA/Ao ratio, LVIDd dimension, and LVIDd/Ao ratio correlated with the severity of MMVD in point of significant differences and distinct correlations.

Modern Chinese Literature, the so-called 'feminist' is a very modern and the traditional criticism and took an important position in the double action. Because a woman's freedom from the bondage of traditional ethics of restoring the social status equal to men but to women does not give, that compared to men and women just the dimension of the problem of isolation is not just. It is dominated by yugajeok worldview by streamlining the whole Chinese society to build a modern society and the country was a critical task. However, multi-cultural life of Lin, Hui-yin and Ling, Shu-hua in the history of the world's attention to the shrine was worried attention to soils, rather than East-West dualism law by taking a mixture of both women in modern Chinese literature and Western literature from the center of efforts to overcome the traditional point hayeotdaneun feminist literature that may be different. Lin, Hui-yin and Ling, Shu-hua to overcome the Western-oriented culture really the true dream of China's globalization and localization could be regarded. She naesewotdeon the banner of feminist literature in the traditional 'anti feudal', 'free personality' silcheondoen under such slogans as well as women's liberation from traditional, male-oriented perspective away from the women's unique experiences and new understanding of the value of the superiority the concept of a woman, and was to create. In particular, the femininity of these women who traditionally associated with women and the unique culture - the creation of a new consciousness, a re-evaluation of traditional feminine skills and talents was to try to.

The spinal cord or CSF surgery is a very complex process. It requires continuous pre and post-surgery evaluation to have a better ability to diagnose the disease. To detect automatically the suspected areas of tumors and symptoms of CSF leakage during the development of the tumor inside of the brain. We propose a new method based on using computer software that generates statistical results through data gathered during surgeries and operations. We performed statistical computation and data collection through the Google Source for the UK National Cancer Database. The purpose of this study is to address the above problems related to the accuracy of missing hybrid KNN values and finding the distance of tumor in terms of brain cancer or CSF images. This research aims to create a framework that can classify the damaged area of cancer or tumors using high-dimensional image segmentation and Laplace transformation method. A high-dimensional image segmentation method is implemented by software modelling techniques with measures the width, percentage, and size of cells within the brain, as well as enhance the efficiency of the hybrid KNN algorithm and Laplace transformation make it deal the non-zero values in terms of missing values form with the using of Frobenius Matrix for deal the space into non-zero values. Our proposed algorithm takes the longest values of KNN (K = 1-100), which is successfully demonstrated in a 4-dimensional modulation method that monitors the lighting field that can be used in the field of light emission. Conclusion: This approach dramatically improves the efficiency of hybrid KNN method and the detection of tumor region using 4-D segmentation method. The simulation results verified the performance of the proposed method is improved by 92% sensitivity of 60% specificity and 70.50% accuracy respectively.
