Solar Photovoltaics (SPV) In India has become an important renewable source of energy particularly for rural and remote areas. The vastness of the country and the requirements of electricity in far-flung villages makes SPV very attractive, with inherent technological advantages providing additional boost. This has been recognized very early by Govt. Of India and Ministry of Non-Conventional Sources of Energy (MNES) has been entrusted with promoting SPV usage in the country. Rural electrification through SPV systems is one of the programmes which is expected to provide fillip to PV industry in the country. PV Industry in India is very well established with capability of solar cell fabrication and module fabrication as well as Balance of System design and fabrication. There several R&D groups in the academic institutions who are involved in improving solar cells efficiency, thin film solar cells and PV instrumentation. Thus, India provides a ready market for large scale utilization of solar energy through SPV technology.

The first RDF production plant in Korea is going to start commercial operation at Won-Ju city in October this year, where municipal solid waste is treated and converted to RBF. Korean government is preparing the quality standard of RDF and starting a new waste policy of RDF promotion instead of general waste treatment technologies such as incineration or landfill. In Europe the EU member states have decided the united quality standard of RDF to increase the amount of new & renewable energy through the promotion of RDF utilization. New quality standard of RDF and trade market of RDF in Europe is introduced in this paper.

This study was conducted on young children safety helmet to prevent risk of head injuries from external shock. Young children helmet shall be easy to wear and use comfortably. But the young children helmet market in domestic has imported dependently and widely variations in quality because the euro product of high priced and the east asia product of low priced are selling at the same time. Therefore, this study surveyed children under 13 years of age and Married people and studies their actual state of wearing. Furthermore, this study is going to propese the improving wearing of helmet and the major points of quality of helmet and the problem by comparing and reviewing regulations of domestic and foreign.

The purpose of this study is to develop an application that supports a user in the maintenance of small photovoltaic device. To this end, this study analyzed the maintenance status, related regulations and existing application contents in Korea. According to the analysis results, most users did not maintain device for themselves. In addition, the maintenance market has not been activated due to its low profitability. Regulations on the maintenance of photovoltaic device prescribed by the KESCO and Japanese counterpart were analyzed to establish the standards for photovoltaic device inspection, and an application was developed based on the existing applications and research results. In order to evaluate the completeness and satisfaction of the developed application, it surveyed 52 users and 22 experts. The survey results showed that the completeness was calculated to be 90 points, and the level of satisfaction was 93 points on a 100-point scale. Therefore, it is expected that the maintenance application developed in this study will be useful for users to maintain the photovoltaic device.

As environmental pollution has become worse green technologies to replace or reduce consumption of fossil fuel get spotlight from government, industry and academia globally. It is reported that 40% of carbon dioxide emission is caused by electricity power generation. And 37% of end user electricity power is used by residential costumer in US. Smart Grid is considered as one of promising technology to alleviate severe environmental problem. In residential environment, Home Energy Management System (HEMS) can play a key role for green smart home. The HEMS can give several benefits like aslowering electric utility bill, improvement of efficiency of electric power consumption and integration of generator using renewable energy resources. However just limited functions of HEMS can be used for residential customer in real life because of lack of smart function in home appliances and optimal managing software for HEMS. This study provides comprehensive analysis for Home Energy Management System for residential customer. Simple HEMS system with real products on the market are explained and limitation of current HEMS are also discussed.

Kimchi industry in Korea has grown rapidly with the increasing domestic and overseas demand of Kimchi. Currently, there is an increase trend of consuming the commercial Kimchi products, although the Kimchi consumption/adult/year is decreasing (36.6 kg in 2018). The amount of commercial Kimchi consumption in 2018 was 757,000 M/T (metric ton), out of 1,892,000 M/T of the estimated total consumption, and the size of Kimchi market was estimated to be 1,398 billion wons. In 2019, 29,628 M/T of Kimchi was exported to 78 countries, and 306,047 M/T was imported, mainly from China. In the future, for the technological upgrading of Kimchi plants, a large capital investment to the production of commercial Kimchi will be required. The accelerated glocalization of Kimchi will bring a steady increase in Kimchi export. Moreover, with the development of global Kimchi culture, the values and images of Korean national brand can be greatly improved.
