Purpose: The purpose of this study was to simplify the traditional manufacturing method of Jeungpyun by developing a new process for Jeungpyun preparation using meringue and to also investigate the quality characteristics of Jeungpyun made with green tea powder. Methods: The Jeungpyun was manufactured as 4 sample preparations (Jeungpyun: J; Jeungpyun+0.5% green tea: J+0.5% GT; Jeungpyun+1% green tea: J+1% GT; and Jeungpyun+1.5% green tea: J+1.5% GT) through mixing rice flour, meringue, green tea powder (0-1.5%), dry yeast, water, and milk, steaming for 4 min at $180^{\circ}C$ and 3 min at $220^{\circ}C$, and then standing for 1 hr at room temperature. The quality characteristics of Jeungpyun were evaluated based on physicochemical properties, total mold, texture analysis, and sensory evaluation. Results: The pH of Jeungpyun batter was significantly lower in J+1.0% GT and J+1.5% GT than J. The specific gravity, weight, volume, and specific volume of J+0.5% GT and J+1% GT was not significantly different, as compared to J. In color, L value decreased and a and b value increased based on the increase of green tea powder. The antifungal activity was the highest in J+1.5% GT, followed by J+1.0% GT, J+0.5% GT, and J, in order. Samples with added green tea powder showed decreased hardness, as compared with J; its effect was significant in J+1.0% GT and J+1.5% GT after storage for 1 day. In sensory evaluation, the color of Jeungpyun was darkened by the addition of green tea powder. The egg smell and hardness significantly decreased by addition of green tea powder. Based on quantitative description analyses, overall acceptability was the highest in J+1% GT. Conclusion: Therefore, 1% green tea powder was the optimal amount for preparing Jeungpyun with meringue. For simplification of the traditional manufacturing method, Jeungpyun could be produced with meringue and green tea powder, which has potent physiological activities.

Freshwater algae (green algae, blue-green algae and flagellated algae) were collected at 103 freshwater sites (including lakes, ponds, swamps, streams, and rivers) throughout South Korea March 2015-October 2016, and were identified using light microscopy. A total of 345 taxa in 2015 and 329 taxa in 2016 were identified and among them, 6 taxa in 2015 and 8 taxa in 2016 were new recorded species in Korea; The new recorded species were Characiopsis malleolus in Xanthophyceae, Phacus mammillatus in Euglenophyceae, Epipyxis utriculus and Lagynion ampullaceum in Chrysophyceae, Bicosoeca planctonica in Bicosoecophyceae and Salpingoeca frequentissima in Choanoflagellatea in 2015, and were Ankistrodesmus bernardii and Quadrigula korsikovii in Chlorophyceae, Didymocystis planctonica in Treubouxiophyceae, Spirulina nodosa, Raphidiopsis curvata and Geitlerinema claricentrosum in Cyanophyceae and Lagynion macrotrachelum in Chrysophyceae, Bicosoeca oculata in Bicosoecophyceae and Salpingeoca rosetta in Choanoflagellatea in 2016.

This review aims to show that industrial sustainable chemistry, minimizing or reducing the ecological impacts by the chemicals, is not an emerging trend, but is already a reality through the application of 'White Biotechnology' such as 'green' chemistry and engineering expertise. A large number of current industrial case studies are presented, as well as new developments from the chemical industry. The case studies cover new chemistry, new process design and new equipment. By articulating the requirements for industrial application of sustainable chemistry, this review also seeks to bridge any existing gap between academia and industry regarding the R & D and engineering challenges needed to ensure green chemistry research enables a more sustainable future chemical industry considering eco-toxicological impacts.

According to the New Town Development Plan, Gang-buk area, a symbol of slum in Seoul will be changed new residential area. There are a lot of challenges for success this project. First of all, new ways of city plan "pre-plan and development" and "environmentally friendly development" are necessary to carry out this plan. Another important idea is how to overcome conflicts such as unbalanced development, a traffic jam and environment problem. Also, Government and a citizen agree that this project have to accept eco-protectable and sustainable development theory. For increasing green area ratio and keeping eco-diversity, planting at roofs and water circulation system in residential complex are compulsory. Green network based on environmentally friendly development provides a natural energe stream on eco-system and protects a city from air pollution, hot air island phenomenon and a flood.

This article is summary of 'Korean Green New Deal' project which strives to revive Korea's Top 4 rivers for the next four years, between 2009 and 2012. The purpose of this project is balanced national development and recovered regional economy, creating new jobs. Details of the 'Korean Green New Deal' include means to reinforce obsolete embankments and to recover the river ecosystem by maintaining sedimentary soil, to install small- to middle-sized dams and flood control reservoirs and to establish eco-friendly reservoir for emergency water supplies. The project is expected to generate 190,000 new employee and create 23 trillion won worth production inducement effect, contributing in the revival of regional economies.

The production of bio-energy crops is a major research project in the emphasizing the "low carbon green growth" strategy. For this, the possibility of the introduction of the new energy crops improve the agricultural income from fanning must be diagnosed. This study describes the level of agricultural income per unit area by cropping system based on the income of crops in the field. Especially, we have chosen the southern part attracting the attention in the possible area of the bio-energy crop production. This study consists of five chapters. Chapter I is the introduction. Chapter II is on the status of the southern part cropping system and the analysis of the economic value. Chapter III is on the economic value analysis introducing new bio-energy crops. Chapter IV is on the comparative analysis for the economic value of the croping system introducing new bio-energy crops. Chapter V is the conclusion.

Energy systems in increasing energy efficiency are actively performed at home and abroad. But Generally systems in the country are limited in a new building or sort of some buildings like a public and office building. So, this research suggest a new direction of energy system for existing buildings. It need to set a new bound for containing the green remodeling. For a direction, we analysis domestic energy system in perform and compared their bounds, standard and methods of energy evaluation. This study is necessary for an additional research for proposing detailed evaluation items and for a feasibility study research. And it contribute to develope internal energy systems and set a new system bound.

Recently, the housing market in Korea has been changed from new construction to building-stocks, and focusing on supplier to focusing on users. Open housing is a design method not only content to users' various needs but also to the means of sustainable development by adapted to longevity of buildings. There are some indicators for Open Housing related to Green Building Certification Criteria which were worked by Mock & ME. But those indicators are limited to flexible design methods. This is a basic study for the selecting of Open Housing indicators for complementation of Green Building Certification Criteria by the analysis of SI housing in Japan, domestic Green Building Labelling and those of other countries.

This study focus on the revitalization of green tourism by the agricultural landscape conservation policy. Today, agricultural landuse for food production is restricted by agricultural products import. In this context, agricultural land use policy should be paradigm shift to the consumers needs which accelerates the green tourism in the rural areas. This research screen the agricultural landscape conservation policy of Japan' system and construct the new policy implementation for agricultural landscape conservation in Korea. For this purpose, agricultural landscape guideline and support system should be established in line with the revitalization of green tourism and agricultural income diversification in the rural areas.
