Vegetables and fruits contain a great deal of vitamins, minerals, dietary fiber and phytochemicals. Therefore, healthconcious consumer prefer beverage made from fresh fruits and vegetables due to their health benefits. This study was conducted to investigate differences in nutritional composition and sensory characteristics of juices depending on the apparatus used: either a low-speed juicer or high-speed blender. All ingredients could be made into juice without addition of water using the low speed juicer. However, addition of water was necessary to produce juice with the high-speed blender. Phenol and flavonoid content, were higher in juice made with the low-speed juicer than that produced with the high-speed blender and were correlated with DPPH radical scavenging ability. Protease activity of pineapples juices was not significantly different for the two methods, but protease activity of kiwi juice was about 8 times higher in juice made with low-speed juicer than that made with the high-speed blender. SOD activity also tended to be higher in the juice made with low-speed juicer. The concentration of dissolved oxygen in the juice made with high-speed blender was higher than that of juice made with a low-speed juicer and was correlated with color change. In addition, the high-speed blender caused an increase juice temperature, but temperature was not changed during use of the low-speed juicer. The noise level of the low-speed juicer was low, but the high-speed blender had high noise intensity comparable to that of railway or aircraft noise. In the sensory evaluation of juice, juice made with the low-speed juicer was preferred over juice made with the high-speed blender. As a result, the overall quality of the juice produced using the low-speed juicer was superior.

In general, the silo blender is composed of silo, blending cone and vane. This study is to develop the blending system for resin of industrial materials produced in the chemical plant By examining closely the How states at the six flow zones of different geometry in the blender due to the gravity of resin, it is possible to develop the silo blender by the optimum design through the sin and the capacity change.

The results of process development for the blending of waste salt from the electrorefining of spent fuel with zeolite-A are presented. This blending is a key step in the ceramic waste process being used for treatment of EBR-II spent fuel and is accomplished using a high-temperature v-blender. A labscale system was used with non-radioactive surrogate salts to determine optimal particle size distributions and time at temperature. An engineering-scale system was then installed in the Hot Fuel Examination Facility hot cell and used to demonstrate blending of actual electrorefiner salt with zeolite. In those tests, it was shown that the results are still favorable with actinide-loaded salt and that batch size of this v-blender could be increased to a level consistent with efficient production operations for EBR-II spent fuel treatment. One technical challenge that remains for this technology is to mitigate the problem of material retention in the v-blender due to formation of caked patches of salt/zeolite on the inner v-blender walls.

In this study, we have suggested a method to create 3D animation based on STL files which are easily available on the internet using Blender, which is one of the most popular open-source 3D modeling SW. And the procedure of making 3D animation using STL file was compared with those for OBJ or FBX files as well. Contrary to OBJ and FBX, STL files do not contain information regarding hierarchy, material and texture which are very important in making 3D animation. Especially the absence of hierarchy may cause serious problems in rigging, which involves movement of unwanted parts of 3D object during rigging process. It is demonstrated that the weight painting feature of Blender could be a solution to tackle the faulty rigging due to attributes of STL files. The effect of the sampling frequency and the resolution on the rendering time is also investigated with respect to the 3D mantis animation. It is also seen that insect models by 3D printer could be used as a new type of pedagogical material in the elementary science education.

In a mediator based information integration system that integrates information distributed on various data sources as a common data model, there are many researches on a common data mode providing a reservation of integrated data semantic, and on a resolution for a conflict caused by integrating various data modes. This paper proposes the DataBlender system that minimizes the semantic losses and provides an easy resolution for a conflict using the XML technology like as XML Schema, XQuery. Futhermore, it provides an integrated query facility usable in the mobile environment. So it becomes a foundation for a next Internet business environment.

This paper presents a novel reference variable speed control scheme of a BLDC motor for the high-speed blender machine according to the current limit. Because of a pulsating load variation of a high-speed blender machine, the actual speed is pulsated by the current limit in the high-speed region. The proposed control scheme uses a variable reference speed to reduce the speed variation from the current limit in the constant power region. The pulsated load is occurred at the material crushing, then the pulsated load is reduced after grinding. The reference speed is smoothly reduced at the pulsated load variation, then the enough torque can make a constant speed during crushing. When the pulsating load is reduced, the reference speed is automatically increased to the original speed value. The proposed control scheme is verified by experimental result by practical blender machine.

The Internet of Things (IoT) interconnects every device by allowing them to communicate directly and share information with each other and has been recently applied to various industrial fields. The integration of home appliances with IoT has led to the creation of new markets by providing quick and better experience to consumers. Although IoT has been integrated into most modern day appliances, there have been few developments for kitchen appliances. This paper presents the development of integrating IoT with the blender, one of the most widely used appliance in the kitchen. A custom application was made to interact with the blender that provides three main functions: digital controller, maintenance, and defrosting alarm. The function of digital controller provides wireless control to the conventional blender. The maintenance function detects and alerts the user on blender reliability with the intent of enabling the anticipation of hardware failures. The defrost alarm alerts the user when the ingredient has reached the appropriate and desired temperature when cooking frozen food.

The purpose of this study is to clarify which some factors among the socio-demographic factors have effect on the housewives behavior on how to buy small electric appliances and how to use them. The questionnaires were distributed in July 1985 to 491 housewives in Seoul. Satistical methods as percentage, frequency, arithmetic mean, chi-square test, t-test and F-test were used for data analysis. RESULTS : 1) The average rate of possessing the automatic rice cooker is 87.8%, the electric frypan is 81.0%, the toaster is 36.9% and the blender is 86.9%. 2. Generally the frequency of use were low. 3) Generally their knowledge on small electric appliances is low. 4) The ability of management in blender was influenced by age, education and in automatic rice cooker was influenced by only education.
