Flexible and wearable electronics have huge potential applications in human motion detection, human–computer interaction, and context identification, which have promoted the rapid development of flexible sensors. So far the sensor manufacturing techniques are complex and require a large number of organic solvents, which are harmful not only to human health but also to the environment. Here, we propose a facile solvent-free preparation toward a flexible pressure and stretch sensor based on a hierarchical layer of graphene nanoplates. The resulting sensor exhibits many merits, including near-linear response, low strain detection limits to 0.1%, large strain gauge factor up to 36.2, and excellent cyclic stability withstanding more than 1000 cycles. Besides, the sensor has an extraordinary pressure range as large as 700 kPa. Compared to most of the reported graphene-based sensors, this work uses a completely environmental-friendly method that does not contain any organic solvents. Moreover, the sensor can practically realize the delicate detection of human body activity, speech recognition, and handwriting recognition, demonstrating a huge potential for wearable sensors.

The fashion is always limited in time and the new evolutionary round of the fashion industry (FI) development will not be an exception. The independence of FI is a result of changing opportunities and needs of a person as a consumer. The person­consumer is dependence on the gadget. Nowadays, it directly affects the new technologies of the suit and clothes creation. New requirements have influenced the rapid development, the growing value of the Internet, the e­commerce and the new technologies of the clothes creation. They are the 3D, 4D printing, nanotechnologies (NT), smart clothes: the wearable electronics and smart clothing for healthcare, biofabrication (BF), etc. The emergence of the new technologies in the environmentally friendly clothes creation permitted to process the waste and the salvage into new materials. It gave the chance to globally reconsider the relations with the environment and the consumption without killing animals. It was found out that the latest development reflected the epoch, the time and the human needs of the Third Millennium. This research introduced the new term — Independent New Fashion (INF), in order to highlight the independent historical moment of the new round of FI evolutionary development. The further research is crucial in this field. The subject of the paper is the creation, the presentation and the development of the independent fashion and the new clothes. The chronological framework of the paper ranges from 1996 till the present time.

<div class="WordSection1"><p>Each country has a unique personality that becomes the country's identity. Indonesia is known as a country that has community participation culture. However, that identity has been fading amid globalization today. As a matter of fact, community participation culture has the potential to be the unique culture of Indonesia in conquering the world through the conscious choice to defend the country for the unity of the nation. Research method employed in this study is literature review and observation based on author’s previous research. The result is analysis for the application of community participation culture in the management of renewable energy towards energy independence reinforcing state defense through the implementation of the basic principles of community participation which includes: (1) community develops, provides and utilizes renewable energy sources together; (2) community becomes the pioneer and innovator that can facilitate other community in independently providing and propelling the growth of people’s economy to reinforce state defense. Renewable energy management through state participation should not only be a normative advice, but should be clearly regulated to ensure people’s active participation in achieving the 23% target for renewable energy mix in 2025. There is a need to optimize the sustainable coordination, evaluation and supervision between Ministry of Energy and Mineral Resources, Ministry of Village, Development of Disadvantaged Regions and Transmigration as well as Ministry of Defense in order to ensure people’s participation in creating sustainable renewable energy management and as a form of defending the state.</p><p><strong>Keywords</strong>: defending the state, renewable energy, community participation culture</p></div>

Energy Management Strategy

Energy storage systems are a topical modern area of research due to the rapid development of renewable energy and electric vehicle construction. Due to the current lack of a source or accumulator of electricity with high specific energy and power, it is being replaced by hybrid electricity storage systems, which consist of separate, complementary sources. Among them, the combination of electrochemical battery – supercapacitor bank is the most common. The paper considers its active configuration, in which both sources are connected to the output network through bidirectional pulse DC-DC converters. The studied hybrid batterysupercapacitor system is a nonlinear dynamic system with multiple inputs, multiple outputs, and two control channels, the operation of which is described by five differential equations. To solve the problem of synthesis of a stable and efficient control system for such an object, the energy approach, namely energy-shaping control has been used. To do this, the studied system is mathematically described as Port-Controlled Hamiltonian system, and two descriptions are compared with different options for choosing the basic vector of the system state. The structural synthesis of the passive control system was performed by the Interconnection and Damping Assignment method. Based on the energy management strategy developed for the system under study, all possible options for introducing interconnections and damping into the passive control system were explored using a computer program developed in the MathCad environment. The effectiveness of the obtained structures of control influence formers on the investigated dynamic system was studied by computer simulation in the Matlab/Simulink environment. According to the results of the research, the variant of control influence former with the best combination of introduced interconnections and damping is formed according to the principle of superposition. To stabilize the voltage values of the output network and the supercapacitor unit set by the control strategy, a proportional-integrated voltage regulator is additionally used, and a sliding regulator between two passive control structures is exploited to limit the allowable battery current. The results of the computer simulation showed the full implementation of the tasks of the energy management strategy, including a smooth increase and limitation of the battery current

With the rapid development of economy and technology, enterprises in eco-industrial symbiosis network (EISN) are facing enormous challenges. However, the emergence and development of EISN is closely tied with the energy management in eco-industrial park (EIP). This paper takes institution construction, allocation and new technology of energy management, cooperation performance and long-term cooperation relationship into research and develops a theoretical model of energy management accordingly. We conduct statistical analysis and Structural Equation Modeling using SPSS17.0 and AMOS17.0 based on 241 valid questionnaires from the EISN enterprise managers. The findings indicate institution, allocation and new technology are significantly positively related to cooperation performance, and cooperation performance has positive significant influence on long-term cooperation relationship. Based on the above results, the relative strategies and suggestions of strengthening energy management to enhance cooperation performance are given.

Operation Cost

With the rapid development of the internet, the number of offline customers in the bank branches decreases, and the existing layout of branches leads to the increase of operation cost, which has an impact on the sustainable operation of commercial banks. Adjusting and optimizing the layout of the physical branches of commercial banks can not only reduce the operation cost of banks and avoid the waste of resources, but is also crucial to the sustainable operation of commercial banks. First, an evaluation index system (deposit; loan; number of vouchers; maintenance, establishment, and modification of customer information; number of counter transactions) is constructed to reflect the operation performance of bank branches. Second, the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is used to rank the bank branches. Then, a combination of factor analysis and assignment method is used to identify redundant bank branches. Last, cluster analysis is used to find alternative schemes of redundant bank branches. Finally, Shaanxi Rural Credit Cooperatives Union in Hanzhong, Shaanxi Province, China is selected for empirical analysis. The results show that: four redundant bank branches are identified, and alternative combination schemes of the redundant bank branches are determined. The redundancy identification method in this paper is helpful for commercial banks to allocate various resources rationally and reduce operation cost, so as to ensure the sustainable operation of commercial banks.
