Recently, three-dimensional (3D) nano-processing technology that can increase design freedom and space efficiency of devices has been being rapidly developed, and is highly expected to provide a key path for the development of next-generation optical devices. This technology has shown a high possibility of success in realizing the future devices, but still are facing many challenges in the popularization and practical application. In particular, the ability of quickly, precisely, and stably fabricating complex 3D nanostructures composed of many individual elements is strongly demanded. In recent years, the so-called four-dimensional (4D) nanofabrication technology is attracting attention. The 4D nanofabrication is achieved by applying an external force to manufactured two-dimensional nanostructures, inducing deformation in time, and then precisely transforming them into 3D nanostructures. The 4D nanofabrication technology with excellent flexibility, versatility, functionality, and reconfiguration properties provides a new paradigm enabling effectively control the mechanical, electrical, and optical properties of existing materials. In this review, we examine the conventional methods for fabricating 3D nanostructures, and then investigate 4D nanofabrication technology in detail.

The popularization of streaming networks and mobile devices brings a new kind of network called mobile peer-assisted streaming network. In this network, service provider not only offers downloading services, but also pre-pushes resources to users for caching. Users can download their demanded resources while working as servers for uploading the cached data. Also the mobile characteristic makes high package losing probability in this network. So we study how the service provider pre-pushes or the user downloads resources efficiently and effectively while considering the package losing in this paper. We build utility models for service provider and user, and solve the models using Bellman's theory to achieve Nash Equilibrium which shows the service provider's optimal pre-pushing speed and user's optimal downloading speed. The numerical simulation demonstrates the efficiency and effectiveness of our proposed pre-pushing and downloading scheme by comparing to the traditional scheme.

This research obtained fundamental data for the development of grape foods by investigating the preference for grape foods, popularization and commercialization plan of grape foods and obtained knowledge required in order to develop grape foods. The study used 354 consumers in Seoul and GyeongGi Province. The distribution of sex on research subjects was as follows. Male was 52.0% (184 persons) and female was 48.0% (170 persons). Age distribution varied by twenties and less than twenties being 30.8%, thirties being 26.3%, forties being 24.6% and the fifties and over being 18.4%. According to the results, preference for grape foods of subjects was that rice wrapped in grape leaves ($2.14{\pm}0.7$) and sweet steamed rice($2.12{\pm}0.8$) were the highest among staple food; grape vinegar($2.38{\pm}0.7$) and grape taffy($2.25{\pm}0.7$) were the highest among spices; grape jelly ($2.53{\pm}0.6$) and grape pudding($2.45{\pm}0.7$) were the highest among snacks; grape juice ($2.70{\pm}0.5$) and grape yogurt($2.59{\pm}0.6$) were the highest among beverages. Subjects responded to the fruit group among food groups harmonized with grape foods(p<0.01). 50.7% of subjects responded to "have to be delicious" and 25.1% of subjects responded to "nutritional balance" as the most important aspects of the development of grape foods. In the popularization and commercialization plan of grape foods, Subjects chose with respected importance, personal preference($4.15{\pm}0.8$), price($4.05{\pm}0.8$) and promotional strategy($4.00{\pm}0.9$). In conclusion, the food development and revitalization plan should use grapes to find out food materials suitable for grape mixture and nutritional balance. We will expect an increase population and commercialization of grape foods if we develop grape foods and promote strategically in consideration of the preference of consumers and the price of produce.

The popularization of smart devices and subsequent optimization of their sensing capacity has resulted in a novel mobile crowdsensing (MCS) pattern, which employs smart devices as sensing nodes by recruiting users to develop a sensing network for multiple-task performance. This technique has garnered much scholarly interest in terms of sensing range, cost, and integration. The MCS is prevalent in various fields, including environmental monitoring, noise monitoring, and road monitoring. A complete MCS life cycle entails task allocation, data collection, and data aggregation. Regardless, specific drawbacks remain unresolved in this study despite extensive research on this life cycle. This article mainly summarizes single-task, multi-task allocation, and space-time multi-task allocation at the task allocation stage. Meanwhile, the quality, safety, and efficiency of data collection are discussed at the data collection stage. Edge computing, which provides a novel development idea to derive data from the MCS system, is also highlighted. Furthermore, data aggregation security and quality are summarized at the data aggregation stage. The novel development of multi-modal data aggregation is also outlined following the diversity of data obtained from MCS. Overall, this article summarizes the three aspects of the MCS life cycle, analyzes the issues underlying this study, and offers developmental directions for future scholars' reference.
