Recent rapid development of computer, information communication and Web service technologies is exerting considerable effects on all industrial areas. As such digital technologies are also introduced to the clothing and fashion industry and create 'virtual garment environment' consisting of 3D virtual bodies, virtual garments and virtual try-on systems, consumers are now able to try virtual garments on their virtual body online. This study was conducted in order to analyze consumers' tendency of clothing purchase using 3D virtual simulation technology, which is increasing attention throughout the world, and to propose strategies on the development of virtual try-on technology for activating apparel online shopping. The subjects of this study were men and women aged 18 or older living in the North Carolina State, U.S., and a questionnaire survey was conducted with them on their tendency of apparel online shopping and their preference for real garments and virtual garments. According to the results of this study, consumers' awareness of apparel shopping using virtual try-on was still low. Moreover, in the results of surveying consumers' purchase preference for real garments and virtual garments, preference was highest for real garment (P), which was followed by virtual garments OA, OB and BB. Based on the results of this study, for the activation of apparel online shopping using virtual simulation technology, it is considered necessary to provide services implementing virtual try-on similar to consumers' actual try-on. This requires further active research and technology development on virtual try-on simulation using digital technologies.

Digital twins are digital replicas of objects and systems in the real world. These digital replicas in a virtual environment can be connected with smart sensors and a variety of analyses, and simulations of real-time data from these sensors enable effective the operation, rapid feedback, and future predictions of real world phenomena. Until now, digital twins have been adopted and used mainly in the field of manufacturing, especially for smart factories. As digital twins are expected to be useful not only for productivity improvement but also for social problem solving, it is predicted that they will be extended to other fields such as those of transportation and cities. Digital twins will especially help realize smart cities through real-time monitoring, operation, and predictions using virtual digital twin cities. This paper summarizes the trends in digital twins for smart cities, the concept of digital twins, their application to smart cities, the strategies of various countries, and the development status of companies.

Digital Twin technology is rapidly transforming various industries by providing comprehensive virtual models that replicate physical objects or processes. In the context of agriculture, digital twin can be a game-changer. This technology can help in creating precise simulations of farming scenarios, thereby enabling farmers to make data-driven decisions and optimize farm operations. The potential benefits include improved crop yields, resource efficiency, and environmental sustainability. However, the implementation of digital twin technology in agriculture poses challenges, such as data management issues and the need for robust IoT infrastructure. Despite these hurdles, the future of digital twin in agriculture looks promising, with ongoing research and developments aimed at overcoming these obstacles.

A fundamental problem in the in-line digital holography microscope is that the real image and virtual image and zero-order image are not separated spatially. In this paper, we have eliminated the zero-order noise by an averaging method and the twin image is divided using a geometrical set-up in an in-line digital holographic microscope. The size of the virtual image depends on the distance between the objective lens and the hologram plane and on the distance between the hologram plane and the image plane. We found that the virtual image size is smallest when the distance between the objective lens and the hologram plane is equal to the back focal length of the objective lens. We could divide the virtual image and real image by controlling the distance between the hologram plane and the objective lens.

There have been many experiments and researches of virtual marionettes which mostly focused on controlling the marionettes more delicately and precisely. This paper will prove that performances using virtual marionettes can show more than simply controlling other objects delicately and precisely. The performance that this paper is discussing about used not only a virtual marionette but also an actual marionette. In this performance, a human manipulated an actual marionette and the actual marionette controlled a virtual marionette. This performance is meant to represent a controlling relationship between an actual world and a virtual world. This recursive and duplicate process will show that experiments using virtual marionettes can express more diverse objectives than existing experiments.

A virtual reality is a virtual space constructed by a computer that provides users the opportunity to indirectly experience a situation they have not experienced in real life through the realization of information for virtual environments. Various studies have been conducted to realize virtual reality, in which the user interface is a major factor in maximizing the sense of immersion and usability. However, most existing methods have disadvantages, such as costliness or being limited to the physical activity of the user due to the use of special devices attached to the user's body. This paper proposes a new type of interface that enables the user to apply their intentions and actions to the virtual space directly without special devices, and test content is introduced using the new system. Users can interact with the virtual space by throwing an object in the space; to do this, moving object detectors are produced using infrared sensors. In addition, the users can control the virtual space with their own postures. The method can heighten interest and concentration, increasing the sense of reality and immersion and maximizing user's physical experiences.

The purpose of this study is to investigate the features of inquiry activities using technology in the 2015 revised elementary science digital textbooks. For this, we analyzed the features of inquiry context and inquiry method presented in inquiry activities using three kinds of technology: Virtual experiment, virtual reality and augmented reality. As a result, firstly, the most common types of 77 inquiry activities were realistic type which shows the phenomenon actually and vividly as possible and realistic-abstract type which shows the phenomena with the abstract concepts. Second, the ways of using three technologies were different depending on the processes of inquiry and the sub-domains of science. For example, virtual experiment technologies were mostly used in the contents of physics and chemistry with the inquiry context of realistic-abstract type for investigating the relationship between variables of experiments and describing the phenomena mechanically. On the other hand, virtual reality and augmented reality techniques tended to be used more frequently in biology and earth science contents with the inquiry context of realistic type for observing and describing the phenomena. Finally, we discussed educational implications in terms of developing and applying technology-based inquiry activities.
