Objective: The aim of this study was to determine the effect of abdominal-compression belt in one leg standing on balance in normal adult. Background: With the effects of increased intra-abdominal pressure, the abdominal-compression belt is contributing to a static balance control. However, specific study is still insufficient. Method: Forty subjects were randomly allocated to two groups: control(n=20) and experimental group(n=20), respectively. The experimental group used an abdominal-compression belt, whereas the control group did not that. All subjects were educated using pressure biofeedback unit and ultrasound imaging for exact application by abdominal-compression belt. Main outcome measurement was used a general stability index, fourier harmony index, weight distribution index, and fall index in tetrax balance system. Results: Experimental group improved significantly on general stability, only 2 factors(eyes closed with head turned forward and eyes closed with head turned backward) among fourier harmony index, and fall index, However, weight distribution index did not revealed significant difference. Conclusion: The findings suggest that application of abdominal-compression belt could be effective on improving balance ability in one leg standing of normal adults. Application: The results of the abdominal-compression belt might help to control balance in workers.

The inside contact characteristics in abrasive belt drives were investigated analytically and experimentally for (1) driver pulley contact wheel and (2) driven pulley contact wheel. The concentrated contact forces in the grinding zone divided the entire belt-pulley contact are by three distinct areas and the tangential friction forces in the active areas caused the normal forces to change, which resulted in the different belt force distribution compared with those of the ordinary flat belt drives. The experimental results for the normal pressure (belt tension) distribution were in good agreement with the theoretical results.

With the rapid growth of high-tech, the development of cultural and creative industries has gradually become the focus of national industrial development. With the proposal of China's "Belt and Road" strategy, the role of cultural and creative industries in the provinces and cities along the "Belt and Road" in the entire international trade is becoming increasingly critical. It is necessary to explore solutions to improve the competitiveness of China's cultural and creative industries, factoring the surrounding cities of the "Belt and Road" as an example. Thus, this paper proposes the six-element diamond model based on innovation capability and government support to render a comprehensive evaluation of the competitiveness of the cultural and creative industries in the 31 provinces and cities across the country. The results show that the overall competitiveness of the 18 provinces and cities along the "Belt and Road" cultural and creative industries is weak. Focusing on the 18 provinces and cities along the "Belt and Road", using the linear regression measurement model quantitative analysis, the four types of influencing factors affecting the development of the competitiveness of cultural and creative industries along the "Belt and Road" were obtained. Finally, according to the four types of influence, the competitiveness improvement plan is proposed from the four aspects: government role, consumption preference, industrial innovation ability, and the introduction of high-quality talent.

The purpose of this study is to examine farmers' intentions, attitudes, and the type of filming they are involved in, including to provide supporting data for planning the agricultural strategy and Green Belt policy in Seoul. All the collected data was analyzed using the contingency tables and the Chi-square test using the SAS computer statistical package. The leaseholders did not want to change the current Green Belt policy for the study area, while the landowning farmers hoped for either its revision or dissolution. Both groups pointed out that the Green Belt policy resulted in the delay of development and complained about the difficulty of changing the land use type. The older generation supported the dissolution of the Green Belt, policy, as compared with the younger generation who wanted to maintain or modify the policy. The leaseholders worried that the possible changes in the Green Belt policy might affect the current agricultural land contract system, whereas the landowning farmers were very interested in easing restrictions on changing land use. The compensation plan, which is indemnified land owners for their loss of restrictions on land use, might be useful to sustain urban farming in the Green Belt.

In this paper, a mathematical model for a belt driven system is proposed to analyse the vibration characteristics of the driving units with belts and the free and forced vibraiton anlyses are carried out. The mathematical model for a belt-driven system includes belts, pulleys, spindle and bearings. By using Hamilton's principle, four nonlinear governing equations and twelve nonlinear boundary conditions are derived. To linearize and discretize the nonlinear governing equations and boundary conditions, the perturbation method and Galerkin method are used. Also, the free vibration analyses for various parameters of a belt driven system, which are the tension of a belt, the length of a belt, the material properties of belts, the velocity of a velt and the mass of pulley are made. The forced vibration analyses of the system are performed and the dynamic responses for main parameters are anlysed with a belt driven system.

The purpose of this study is to evaluate the differences of visual image by variations in the location of the waistline and the width of the round belt of the basic pants. The stimuli are 21 samples: 7 variations of the location of the waistline and 3 variations of the width of the belt. The data has been obtained from 35 fashion design majors. The data has analyzed by frequency, factor analysis, anova, scheffe's test and the MCA method. The visual image by the location of waistline and the width of belt are composed of 3 factors : modernity, comfort and attraction factor. In these factors, modernity factor is estimated as the most important factor. The visual image is modern and attractive as the location of waist line goes down. And when the location of waist line is in the position of natural waist belt, belt of 3.2cm width is visually effective. Belt of 4.2cm width is effective except the position of natural waist belt. The interaction effects between the location of the waistline and the width of the belt have significant differences in comfort and attraction factors. As the main effect, significant differences were observed in all of the three factors according to the location of waistline and the width of belt.

This study clarifies that Scytian waistband had flowed into the Jeoseon Dynasty, and it was settled down to saezodae(which is male belt) and norigae(which is female accessory) and pocket in the Joseon Dynasty. Historical records and relic materials are examined and analyzed by quality assessment. 5 experts performs sensory evaluation for 17 pictures of Scytian waistband, and 42 of norigae, 24 of pocket, 6 of small knife, 11 of belt in the Joseon Dynasty, and finally similarity in form and purpose of use between both of them are come out. Research results are summarized as follows: First, Scytian waistband made with leather and metal was carried in the girdle. Men in the Joseon Dynasty carried various forms of belts as position and jobs such as saezodae, kwangdahae, dongdahae, doa. Trinkets of hopae, jangdo, pocket, etc. are put on belt or separately attached. Belt was not put on the women dress, but more various trinkets were used than those on men dress. Norigae, pocket, and jangdo were used practically and decoratively. Second, The types of Scytian waistband were excavated from the tumulus in the age of three states in Korea, and their form and function are same. Belt of the Joseon Dynasty carried below their chest and up navel, of which the wearing position went upper than before. As women jeogori was shorter, their belt is not necessary and various trinkets were put in their skirt. Finally, this study conclude that Korean traditional belt and trinkets come down from Scythian waistband.

Numerous applications of position controlling devices using servoing technique and transmission of energy through belt drives are practiced in the industry. Belt drive is a simple, lightweight, low cost power transmission system. Belt drives provide freedom to position the motor relative to the load and this phenomenon enables reduction of the robot arm inertia. It also facilitates quick response when employed in robotics. In this paper, precision positioning of a belt driven mechanism using a feed-forward compensator under maximum acceleration and velocity constraints is proposed. The proposed method plans the desired trajectory and modifies it to compensate delay dynamics and vibration. Being an offline method, the proposed method could be easily and effectively adopted to the existing systems without any modification of the hardware setup. The effectiveness of the proposed method is demonstrated through computer simulation and experimental results.
