Abstract: The paper proposed a practice teaching mode by making analysis on Didi data set. There are more and more universities have provided the big data analysis courses with the rapid development and wide application of big data analysis technology. The theoretical knowledge of big data analysis is professional and hard to understand. That may reduce students' interest in learning and learning motivation. And the practice teaching plays an important role between theory learning and application. This paper first introduces the theoretical teaching part of the course, and the theoretical methods involved in the course. Then the practice teaching content of Didi data analysis case was briefly described. And the study selects the related evaluation index to evaluate the teaching effect through questionnaire survey and verify the effectiveness of teaching method. The results show that 78% of students think that practical teaching can greatly improve students' interest in learning, 89% of students think that practical teaching can help them learn theoretical knowledge, 89% of students have basically mastered the method of big data analysis technology introduced in the course, 90% of students think that the teaching method proposed in this paper can greatly improve students' practical ability. The teaching mode is effective, which can improve the learning effect and practical ability of students in data analysis, so as to improve the teaching effect.

Abstract: The timely availability and quality of building product information is critical prerequisite for a successful building delivery process. However, little is known about the processes by which stakeholders acquire and use such data. This contribution documents the results of recent relevant surveys, addressing the building product data processing by planers, clients, and the industry. Web questionnaires and interviews with opinion leaders were conducted. Altogether, over 100 participants provided pertinent insights regarding strengths and weaknesses of the current data representation practices. A comparison of the obtained data with that of an earlier study allows for the documentation of the evolutionary trends in web-based data provision. Most importantly, the results facilitate the formulation of strategies for a more effective presentation and distribution of building product data.

Abstract: An analysis based on questionnaire was conducted to study the technology of highway subgrade disaster prevention and maintenance. A serial of questions related to the subgrade maintenance management, maintenance technique, and existing problems were consulted with 39 experts from local highway administrations, highway management and maintenance centers, highway construction Co. Ltd, road maintenance companies in Guangdong Province. The investigation and analysis results provide a valuable scientific reference for further formulating “the technical specification of the highway subgrade maintenance”.

Abstract: One of the major functions of management, it is the foresight and management of action, in terms of knowledge of risks. In practical decision problems, the decision maker-the manager, is forced to make decisions in conditions of approximate partial knowledge of data necessary to determine the exact consequences of the decision. After the decision is taken, some uncertainty (uncertainty) remains, regarding achieve expected results.The practical application, carried out in S.C. "Mecanica Ceahlău" S.A, aims to demonstrate the complexity of risks categories faced by an organization operating in the manufacturing sector. The paper also illustrates how you can apply different methods to identify and analyze the risks, providing decision makers a comprehensive study and useful for maximizing the value of the organization.

Abstract: According to the economic development and the requirement of leisure activities, the popularity of leisure and recreation become very popular in Taiwan. Thus, How to attract tourists to visit these leisure places becomes as a major issue. The questionnaire and outdoor and semi-outdoor comfort detecting devices are applied to analyze these real factors. The results of questionnaire display that “choose a comfortable time to recreation” and “choose the comfort of shade near the local open space” are most important factors for tourists. Then, filed test results show that actual influence factors of tourist activities are outdoor and semi-outdoor thermal comfort, such as wind velocity and surface temperature of construction materials. Thus, the suitable construction material is imitation wood for creating a comfort place.

Abstract: Manufacturing industries were considered among the sectors with the considerable level of lost work days due to work related musculoskeletal disorders. The aim of the study is to find out the different parts of body affected due to discomfort while operating machines in manufacturing industry. In this study work-related body-part discomfort was assessed in 51 male operators by using a body map and ranking procedure, while operating different types of machines viz, lathe, drilling and grinding machines. The study showed that out of 51 operator’s, 45 reported discomfort in shoulder and neck, 34 in lower back, 32 in upper back, 46 in arm, and 23of the operators reported discomfort in the leg. Correlations between the discomfort level and different postures at different working conditions were higher. Except at the start of the shift, operators felt musculoskeletal discomfort in various body parts throughout the shift, and were highest at the end of the shift. The middle age group operators reported higher levels of discomfort. Keywords: Discomfort; Injury; Pain; Body map; Discomfort assessment; Questionnaire; Musculoskeletal disorders.

Abstract: With the rapid development of our national economy, the fast process of city, regional passenger demand is increasing rapidly, high-speed railway emerging as the times requiring. High-speed railway has many advantages in essence and also some disadvantages. How to use its advantages, how to avoid their disadvantages, is important for the advantageous to improve the interests of the company on high speed railway transport department and railway sector, as well as the social development. Through the way of questionnaire survey, statistics and analyzes the main factors affecting the High-speed Rail passenger flow, provides more active mode of operation for the High-speed Rail department. This paper raised the urgent and realistic basis to improve the service level.

Abstract: Chinese wind power industry needs to raise the flexibility level to adapt the dynamic and complex environment. It is imperative to help the wind power industry to alleviate the influence of environmental turbulence. This paper established an analysis structure for environmental turbulence types including technological dynamic, supply and demand complexity, competitiveness confrontation and policy uncertainty. A questionnaire was designed and used to investigate the main influencing components in different types from experts in the field of wind power industry. By using the method of factors analysis, 19 main components are identified as having a significant influence on the environmental turbulence. The results revealed that the stabilization of wind power industry requires a combined effort from the enterprises and government.

Abstract: An actual condition survey was conducted based on literature review and a questionnaire survey in this study. In a literature review, the overview and characteristics of the Korean boiler market were investigated and the efficiency of the boilers used in Korea was organized. A questionnaire survey was prepared on the basis of these contents. A questionnaire survey was conducted for 2,250 households in Korea. An analysis was made on the basic information such as the family members, income level, residential area and living floor area of survey respondents as well as boiler status such as the possession and use of boilers, a boiler replacement cycle and fuel expenses. Lastly, the implications for the spread of high-efficiency boilers were identified based on the types of boiler possession and the use characteristics of boilers by housing type.

Abstract: Building occupants are important factor in giving information on indoor conditions such as comfort, productivity, building performance and occupants ́ health. Even that, being their appraisal mainly based on subjective judgments, it is difficult to set up a standard and objective method for this purpose. The present work aimed to describe, analyze and compare the most common tests on this topic, in order to highlight critical, failings and strengths.
