spherical hinges, the shape and dimension of the polymer-made spherical hinges are

discussed, and characteristics of 3DOF spatial parallel manipulators consisting of S hin-

ges are achieve that purpose. At the same time, Quanzhou launched the

Made-in-Quanzhou-2025-initiative, to upgrade its traditional industries to technology-

based ones.

4.2. Polymer-made Revolute Hinges

This paper is a study on the spatial mechanism containing a polymer-made S hinge ha-

ving a function of the spherical pair. However, as the previous studies show, the author

studied with respect to the two DOF planar pantograph mechanism and the three DOF

planar mechanism made of R hinges functioning as the revolute pair. This study is the

study of its extension. Therefore, first, characteristics of polymer-made R hinges are de-

scribed. Next, research contents regarding 2DOF pantograph mechanisms and a 3DOF

mechanism made of R hinges are presented.

4.2.1. Fatigue Test — Under a Static Tensile Load And Repeated Bending

Figure 1 shows a polymer-made revolute hinge. A fatigue test was conducted under a

static tensile load W and bending repeated angle ±45°. Bending is carried out by use of

the polymer-made revolute hinge specimen.

Figure 2 shows the fatigue test results of the R hinge. PP (Polypropylene) has displayed

that repeated bending motion of ± 45° can be conducted more than one million times.

From Fig. 2, we discovered that PP (Polypropylene) is a good material for long life


4.2.2. Polymer-made 2DOF PlanarPpantograph Mechanisms and Polymer-made

3DOF Planar mechanisms

On the basis of the fatigue test PP (Polypropylene) was discovered to be a good mate-

rial with a long life. Therefore, first, the 2DOF planar pantograph mechanism shown in

Fig. 3 was proposed and developed (Horie et al. 2006). Figure 1(a) is Version 1 of the

pantograph mechanism. Unfortunately, the direction of the output link changes when two

liner actuaters move. Consequently, we thought of Version 2, shown in Fig. 3(b). This

pantograph mechanism has three parallelograms. Therefore, the direction of the output

link with a short length does not change the direction when two linear inputs move, three

short length links are the same length and parallel; the motion is always parallel, since

the leftmost vertical input link moves vertically as usual.

The popularity of smartphones, Internet, the Internet of things, virtual reality, artificial in-

telligence and other emerging technologies has created a smart and universal education

environment, empowered the education without geographical border and schedule limi-

tation, and improved the life-long learning for all and from all. The learning takes place

not only in formal institutions like school and universities, but also at home, in workplace,

on the way or anywhere at any time. This speech will address the opportunities and chal-

lenges for education in the era of Internet plus or Industry 4.0.

Urban public health is essential for living and development of citizens. In this paper, we

focus on the question whether a certain changing rule for urban public health exists during

urban development around the world. In order to answer this question, eighteen indicators

were firstly selected to describe the status of urban public health from five aspects including

physical health (PH), living condition (LC), social security (SS), environmental quality (EQ),

and education and culture (EC). Subsequently, the weighted sum model was applied to

quantify and compare the states of urban public health for different cities. Then four typical

cities — Beijing, Tokyo, New York, and London with different histories — were chosen as the

cases, representing cities in different stages of development. Based on 2000–2009 data, it

is found that a pyramid structure existed in urban public health for each city where the pyr-

amids of Beijing and Tokyo were relatively similar to each other while that of New York and

London were similar, too. Moreover, a general changing trend in urban public health was

revealed and expressed by different pyramid structures, i.e., from the Beijing pyramid to the

Tokyo pyramid to the New York pyramid, and finally to the London pyramid, amongst which

the relative performance of the five aspects of urban public health was gradually changing.

In other words: PH, LC, SS, EQ, and EC are located in different positions of the pyramids

at different stages. This indicates the social evolution and the change of the urban develop-

ment goal to a certain degree. The changing pyramid structure of urban public health can

be verified, further developed and predicted to guide healthy urban development.
