Abstract： Quantifying eddy mixing in the ocean is a hot and tough problem in the area of physical oceanography. Based on the theory of effective diffusivity, the present study investigated the stirring effects of geostrophic turbulence that lead to stretching, distorting, deforming, and folding of tracer contours. These changes are then related to the efficiency of turbulent mixing. Results show that under the stirring effect of geostrophic turbulence, the length of tracer contour can be quickly elongated and fine-scale tracer filaments and fronts are also generated. This fractal elongation of tracer contour, about 10-20 times longer than the original length, is the dominant contributor to the mixing efficiency, whereas the gradient enhancement associated with filament and front generations only plays a secondary role. On the other hand, fine-scale features are smoothed out by small-scale diffusivity which eventually suppresses the increase of contour length and the generation of tracer filaments. This imposes an upper bound of the mixing efficiency when the stirring and smoothing effects are in a dynamical balance. Through a ‘box-counting’ method, the fractal dimension of tracer contour is also found between 1.4~1.6, indicating a geometric dimension lies somewhere between 1D and 2D. Due to the limitation of data resolution, contour length and thus mixing efficiency may be underestimated. Finally, the present study made an empirical relation between the fractal dimension and mixing efficiency, providing an opportunity for estimating mixing efficiency through a well-developed pattern recognition technique in remote sensing, and a new way of diagnosing ocean mixing and its parameterization.

Abstract： In this age of information, a variety of market information can be obtained and plenty of opportunities often appear. It is very important for investors to seize the opportunity, and it depends on whether they can hold the heuristic information, use and integrate the available information, then develop effective program to make decision timely. Successful investors can seize the heuristic information, distinguish between necessary and redundant information of market and integrate useful information becoming a profitable program which ordinary people are not easy to figure out. This process is creative. The study aims to explore this creative thinking mechanism of market information integration. The study tried to reveal the creative thinking mechanism in information integration of market by using the method of individual test and group test, supported by individual interviews, and carried out two experiments exploring how the quantity of information and the highlighting of key heuristic information affected decision-making results on business investment problem. The information used in experiments was from real market. In experiment Ⅰ, participants were divided into two groups, one group was asked to develop a program according to 6 necessary information, another group was asked to develop a program according to 6 necessary information and 14 redundant information. In experiment Ⅱ, participants were also divided into two groups, one group was asked to develop a program according to 6 necessary information and 6 dynamic redundant information, another group was asked to develop a program according to 6 necessary information and 6 static redundant information, and whether they had marked key heuristic information was randomly assigned to each group. The results of experiments showed that the more information provided to the participants, the larger the space of information integration problem, then the integration process was more difficult; when participants searched in the problem space, they needed to seize the key heuristic information to form an initial intention of thinking and make a clear direction for further search; after the formation of the initial intention was formed, participants needed to select necessary information, eliminate redundant information, and integrate all the information available, thus the initial intention was more refined, and eventually a profitable perfect investment program was formed. The study explored the creative thinking process of market information integration, and the findings of this study could try to apply for the training practice in human resource management. There is still much work to do for this study, including developing test materials, the discrimination of the materials, the effect of working memory capacity and perception.

Abstract：
stroke is a common and frequently-occurring disease in clinic, which is also called stroke and cerebral apoplexy. It has a high incidence and occurs frequently in middle-aged and elderly people.As the population ageing process continues to accelerate, the incidence of stroke in our country has also significantly increased. The main clinical manifestations of stroke are cerebral ischemia, hemorrhagic injury, etc. . The disease has a high rate of disability and mortality, has a serious harm to human health, is one of the most important fatal diseases in the world.The clinical symptoms of stroke, including headache, vomiting, dizziness, sudden visual disturbance and disturbance of consciousness, affect the health and quality of life of patients to a great extent, it can easily threaten the patient"s life and health. Therefore, it is very important to give timely and effective treatment for stroke patients.In order to improve the therapeutic effect and promote the rehabilitation of patients with stroke, it is necessary to pay attention to the effective nursing intervention. A large part of stroke patients have different degrees of disability, such as physical dysfunction, consciousness disorders, and so on, to patients and their families have brought a huge mental and economic burden. Therefore, it is necessary to strengthen the rehabilitation care of stroke patients.With the development of traditional Chinese medicine in our country, the application of traditional Chinese medicine in clinical nursing work is more and more extensive. For example, in the convalescent stage of stroke, the effective rehabilitation nursing of Chinese and Western medicine plays an important role in improving the rehabilitation quality of patients. This study on the recovery of stroke-related studies of Traditional Chinese and Western medicine rehabilitation nursing were retrospectively analyzed.

Abstract： cerebrovascular accident is the most common complication in patients with hypertension, with high incidence rate, disability and mortality. Based on early diagnosis and early treatment, if we can take active and comprehensive nursing measures, it will have a positive impact on the prognosis of patients with hypertensive cerebrovascular accident. With the progress of society and the transformation of medical model, nursing work not only requires patients to receive simple disease care, but also requires patients to provide comprehensive physical, mental and social care. Therefore, it is particularly important to provide patients with good psychological and physical care.

Abstract：近年来，中国沿海处于快速工业化和城市化驱动下的新一轮大规模围填海阶段，环渤海围填海历史久、规模大，已成为我国围填海的重心区域。由于围填海和河口三角洲增长，1940s以来渤海面积萎缩了0.57×104km2，萎缩速率大于82km2/a，2000年以来萎缩速率更高达141km2/a；渤海自然岸线的长度和比例也急剧下降，由1990年的1397km减少为2014年的561km，占岸线总长度的比例由54.92%下降为16.18%。围填海导致多种危害，如：海洋潮波和水动力条件变化，近岸和近海沉积环境与水下地形变化，加剧近岸水环境与底泥环境污染，潮滩湿地面积减损与生态功能下降，底栖生物栖息地减损和群落破坏，侵占和破坏渔业资源"三场一通道"，加剧海岸带自然灾害风险、诱发经济社会系统风险，对产业和经济发展带来不利影响，等。在分析我国围填海监督管理现状和问题的基础上，提出政策建议：改革和优化围填海管理体制，建立陆海协调与联动机制，完善法律法规；严格执行生态红线制度，控制围填海规模与速度，推进和优化保护区建设；开展已围填区及其周边海域环境和生态的恢复与重建；强化已围填区新增土地资源的监管和集约优化利用；加强基础观测体系建设，大力促进科学研究的发展；促进公众、利益相关方及非政府组织参与到滨海湿地的保护。
