E-service portal for freelance community: case study in photography business

This study revealed the limitations of freelancers’ inability to perform portfolios and biographies, their performance ratings to a large community of customers. The difficulties were evident in searching for reliable, qualified and experienced freelancers from multi-channel information sources. These limitations might impact the ability of freelancers selected by customers to perform the required task to the customers’ satisfaction. This research focused on the case study of the freelance community for photography business in southern of Thailand. This aims to establish an online facility in which freelance photographers can publicize their services and performance to potential customers. The concepts entailed in web portals and e-services were the key elements in the development and ensured that its functions worked efficiently. The study employed qualitative methods were used to assess the current practices of web portal and thus determining the requirements for the e-service web portal for freelance community. The practical contribution is that it can aid the effective design and implementation of an e-service web portal for the freelance community of photography business, and it is a massive step towards promoting the freelance community in Thailand.

Smart Incubator for Preterm Neonatal Using Kangaroo Mother Care

Kangaroo mother care is an apparatus that provides closed and controlled environmental for the preterm babies. A Preterm birth is commonly defined as any birth base 37 weeks completed weeks of gestation period. This paper deals with cost effective design of incubator that monitors parameters like pulse rate, temperature, humidity, child security and the readings will be continuously displayed In the LED screen and also monitoring the details to the corresponding doctor, nurse and parents by using GSM. The power failure problem is also eliminated by using solar panel. We also intimate the parents about feeding time, dressing time, ear check, eye check. But many of the existing system does not mentioned about above problem and have adopted only with humidity and temperature and also by manual control. So the main objective of this research is to overcome drawbacks and provide eco friendly service to all common people.

Rancang Bangun Mesin Pemipil Jagung Dua Silinder menggunakan Motor Listrik

<p class="icsmheading1"><em>Seeing the situation of animal feed needs which tend to increase every year, it must be accompanied by the procurement of production machines to reduce the productivity of corn. Corn sheller machine is a tool that serves to release corn kernels from the cob. Along with technological developments that continue to progress, many production machines have sprung up such as corn shellers ranging from those that are operated manually to automatic. Each machine has different advantages and disadvantages. In the design of this corn sheller machine the main driver uses an electric motor. The design of this corn sheller machine aims to help ease the burden on corn farmers in particular. At first the corn shelling was done manually, then it developed using a large selep machine but the costs incurred were relatively expensive. The design of a two-cylinder corn sheller machine uses an electric motor to determine the appropriate design and construction of the corn sheller machine. In this machine there is no corn diameter limit for the shelling process in other words this machine is designed for all sizes of corn. In this design using several stages, namely first planning the design of the engine frame, electric motor, pulley and v-belt ratio and the calculation of the shaft. The result of the design is a machine design that is 1200 mm long, 1200 mm wide and 800 mm high. The sheller machine is driven using an electric motor of 500 watts, Rpm 1400 with a transmission system using a pulley and a v-belt ratio of 1: 1. There is no limit to the diameter of corn kernels in the shelling process using this machine. So it can be concluded that this machine has an effective design and sufficient shelling results, able to reduce post-harvest costs for corn farmers.</em></p>

Investigation of working bodies of cotton cleaning machine

The article included information on how to improve the working bodies of the machine for cleaning raw cotton, including large waste mixtures waste disposal sites. Based on the analysis of the design of cotton ginning machines and working bodies, a new effective design scheme of cotton gin from large contaminants was developed. The recommended multi-faceted columns are characterized by good cleaning of cotton waste and maintenance of fiber quality.

Experimental and numerical analysis of the wear mechanism in spring coil forming die and the effects of die geometry on wear

The present work aimed at understanding the wear mechanism of spring coil forming die and the effects of die geometry on wear. The wear morphology was analyzed by scanning electron microscopy and energy dispersive spectrometer. The main wear mechanism was found to be adhesive wear, and a variant of the Archard wear model was established. The wear distribution in spring coil forming die was numerically analyzed in DEFORM software, and the effects of die geometry parameters on wear were discussed. Numerical results revealed that the wear distribution in the die was uneven and the wear mainly occurred at the sides of the die cavity. The wear depth was greatly affected by the width and angle of the die cavity, whereas the length of the die cavity had little effect. A small cavity width or angle led to severe wear, while a large cavity width reduced the forming quality of the spring coil. Moreover, a simple and effective life prediction method was proposed based on wear results. The findings of this research will be helpful for the effective design of spring coil forming die and the prediction of wear.

Rebranding of Ukrainian Art Museums: Design as a Cultural Strategy

The purpose of the article is to identify the features of branding campaigns of Ukrainian art museums and their impact on increasing the popularity of museum institutions; and finding out the effectiveness of design approaches in such campaigns. Research methods are based on the application of comparative, formal-stylistic, iconological analysis and deconstruction method. The novelty of the research is to analyze the branding campaigns of art museums in order to learn from their experience and effective design solutions. The article also reveals the problem of integration of the viewer into the museum environment and the attempt through design to go beyond the imposed stereotypes, to overcome the attitude to art as a field alien to the average viewer. Conclusions. As a result of the analysis of branding campaigns of iconic Ukrainian art museums we come to the conclusion about their efficiency both for separate establishments, and for all culture in general. Comparative analysis of different approaches has shown the importance of identifying the uniqueness of institutions and attempts to reflect it in the design of identity. And although today we can talk about the belated transformation of the museum environment in Ukraine, which has been shedding boring socialist-realist cloaks almost three decades after the restoration of independence, it is important to note that this process coincides with the global trend of renewal of world museums. Design is becoming a cultural strategy that aims more than changing the image: it must turn the museum into a subjective player in the cultural field, able to think not in terms of power but in terms of culture. Therefore, the rebranding of the country’s iconic art museums can be called without exaggeration one of the most important cultural achievements since the restoration of independence. This process also demonstrated the current demand for design as a cultural strategy that can establish visual bridges between art professionals and potential viewers, as well as change cultural codes, set trends and thus influence the change of image of the city and country.
