Depth’ is taken to be the ‘cable depth’ by logging system that is collected at regular depth intervals. Due to the distortion of log measurement caused by cable stretch, irregular motion, and imaging logging tool sticking, serious distortion of logging image occurs, which affects the preparation and acquisition of geological information. Therefore, speed correction is needed to restore the ‘true depth’ of downhole instrument sampling data. In this paper, the motion state of the imaging logging tool is analyzed. Firstly, the Kalman filter model is constructed, and the noise variance of the Kalman filter is corrected in real-time by using a fuzzy logic controller and ‘tool sticking’ identification results, to improve the output accuracy of the system. Through the analysis of logging data, it is found that the method can eliminate the phenomenon of image compression and stretching caused by tool stuck, and restore the subtle characteristics of the formation such as fractures, pores, and bedding, which proves the effectiveness of the technology.

Using the Grey relation analysis method to analyze the relevance of tourism industry in Wuhan city and the city's primary, secondary and tertiary industries, and revealing the coordination of tourism industry and the local national economic development in Wuhan, then calculating the three indicators such as tourism dependence, tourism contribution rate, and tourism pulling rate of Wuhan from 1986 to 2020,it is summarized and refined the time evolution law of tourism industry's pulling effects on the city's economic development in Wuhan. The research results show that GDP of Wuhan is increasingly dependent on the tourism industry, and the pulling effects of tourism on economy in Wuhan is becoming more and more obvious. Among them, the tourism industry in Wuhan has the highest correlation with the tertiary industry, and the correlation with the primary industry and the secondary industry is not obvious, especially the primary industry has basically no correlation. In the context of the rural revitalization strategy, Wuhan City should increase the degree of relevance between the tourism industry and the primary industry to further enhance the pulling effects of the tourism industry on Wuhan's economy.

Abstract: With the fast development in the exhibition economy of China in recent years, the exhibition industry has become the growth pole in promoting economic development in some Cities. However, our exhibition industry has a short history, and many problems could not be neglected on the whole. There is a big gap between our exhibition industry and that of the powers. The competitiveness of exhibition cities is an important standard in assessing complex exhibition strength and prospects. This research will start from the assessing system in the competitiveness of exhibition, and try to build a scientific, reasonable, and practical assessing system in exhibition competitiveness.

Abstract:The purpose of application-oriented undergraduate education is to train application-oriented talents in line with the needs of socialist modernization construction, and it is also the basic requirement of higher education to train employable contemporary university students, while effective education needs to be provided for the targeted training of students’ employability according to their needs. Through pre-employment survey, we can understand the three individual and environmental variables of students’ family backgrounds, admission concepts and personality traits, possess the existing relevant information of students and grasp the causes of students’ demands, for the purpose of providing targeted student-centered education and teaching activities from the perspective of education supply-side. This paper aims to explore the existing employability of the 2020 freshmen, based on the pre-employment survey results of the university freshmen, and further train their employability in the future.

Based on the sample of 36 tourism universities from 2014 to 2017, this paper analyzes the current situation and changing trend of social service efficiency of tourism universities by using DEA-BCC model and DEA-Malmquist index model. The Tobit model is used to analyze the relationship between regional economy, university-enterprise cooperation, talent quality and R&D institutions and the social service efficiency of tourism universities. The research findings are as follows :(1) the social service efficiency of tourism universities has been hovering around 0.8 for a long time from 2014 to 2017, and nearly half of tourism universities have not achieved DEA effectiveness every year from 2014 to 2017, which still has a lot of room for improvement; (2) From 2014 to 2017, the average value of total factor productivity index of social services of tourism universities was 1.19, indicating that the average annual growth rate of total factor productivity reached about 19%, and the increase of technological progress efficiency was the main reason; (3) Talent quality and school-enterprise cooperation have positive effects on social service efficiency of tourism universities; (4) Regional economy and R&D institutions have a negative effect on the social service efficiency of tourism universities.

Abstract: In order to improve the intellective level of water resources management, a real-time water level recognition method based on deep-learning algorithms and image-processing techniques is proposed in this paper. The recognition process is composed of four steps. Firstly, for the purpose of digit detection, YOLO-v3 model is deployed for extracting numbers from the water gauges. Then, the cropped number images are fed into the LSTM + CTC model as training samples so that digits can be recognized. In the third step, Hough transform are adopted to correct the tilt of water gauge in terms of the vertical edge feature. Morphological operation, associated with horizontal projection would position upper and lower edge of water gauge to recognize the scale lines correctly. Water level could be determined correspondingly. Model application shows that the recognition model has satisfying accuracy and efficiency, with potential being applied in practice.

Based on the perspective of information asymmetry theory and transaction cost theory, this paper discusses the effect of agricultural industrialization organizations on the quality of agricultural products. Through the survey of litchi growers in Guangdong Province and surrounding areas, it designs indicators suitable for measuring litchi quality from the two dimensions of safety and texture, uses factor analysis, correlation analysis, OLS model to test the hypothesis proposed herein. The results show that: the involvement of agricultural industrialization organizations has played an important role in improving litchi quality of growers. Enlightenment: unified management and unified standards through industrial organization forms such as enterprises, cooperatives, and associations are an important way to implement large-scale production of litchi, strengthen respective advantages, share risks, seek mutual benefit and win-win results. Government departments should play a leading and propaganda role, provide financial and technical support, improve the service system for the industrialization of the litchi industry, cultivate leading litchi enterprises, and accelerate the development of professional litchi cooperatives, associations and other intermediary organizations to make them become standardized and competitive main market players.

Abstract: General education, which promotes the coordinated development of people's physical and mental health, intelligence and the life value outlook, has become a hot topic in China's educational field. It covers the quality education previously advocated. However, we find some issues in the process of research on general education, such as the low correlation and lack of cooperation among scholars, as well as the implementation difficulties and concept ambiguity in its development in China. To analyze and research the development of general education, we construct a visualized knowledge map based on a large amount of related literatures, including its development history, regional institutions, statistics on publication volume of core authors and the correlation of high-frequency keywords. Accordingly, this paper quantitatively reveals the development history, research focus, hot topics and trend of the general education in China, and it is able to provide reference for the future research in the field.
