국제적으로 관심이 증가되고 있는 지구 온난화와 환경문제는 제조업체, 유통업체, 서비스업체 뿐만 아니라 교육현장에 있어서도 매우 중요한 이슈이다. 창의성 증진에 대한 기대로 성장하고 있는 로봇교육은 OECD 및 EU 국가정부의 환경영향 카테고리인 유독성, 비에너지 자원고갈의 문제와 연결된다. 본 논문에서는 r-Learning을 위한 교구로봇교육에서 환경이슈를 고려하는 미래지향적 Green UCR(User Created Robots)에 대한 이론적 개념을 정립하고자 한다. 그리고 교과부에서는 '친환경 그린스쿨 조성사업'을 추진하고 있는데, 창의성 증진뿐만 아니라 환경보호에 대한 인지적 교육 효과가 매우 큰 초등학교의 Green 로봇교육은 제대로 조명받고 있지 못하는 실정이다. 이에 국내외 Green 로봇 제품 및 교육 현황을 살펴보고, 국내의 초등 방과후학교 로봇교실에서의 연간 전국 건전지 사용실태 추정수치와 교사의 Green UCR에 대한 이슈를 조사하여 제시하고자 한다. 마지막으로 이를 토대로 업체, 교육기관, 정부를 위한 그린 UCR 교육 서비스를 위한 가이드라인을 제시한다.

The purpose of this study, as a part of developing a new french dressing, was to present the best conditions to make improved kiwi dressing, suitable for the tastes of modern people, the processing and cooking methods of different ratios of green kiwi and gold kiwi have been sought to develop a new type of dressing, then its antioxidant have been defined, and used for producing kiwi dressing. Each 150g of different Kiwi purees, made based on the most preferable combinations from the pre-test were used for kiwi dressing, and thereafter its quality characteristics, and physical properties were investigated, as well as a sensory test was conducted. The highest viscosity of kiwi dressing was test sample GD2, and in general that of combining both types of kiwis were higher than that of either single kiwi. The sugar content was decreased by changing the Gold kiwi portion(p<0.05). The chromaticity in general increased with increases in the Gold kiwi portion, and a-value(brightness) and b-value(redness) of sample GD1 were the highest by -2.75 and 17.50(p<0.05). From the acceptability test, the highest overall acceptability was the dressing sample combining Gold kiwi and Green kiwi at a ratio of 1:1. Based on the study results, it is expected that the dressing, made of kiwi puree, mixing Green kiwi and Gold kiwi by 1:1 ratio, and adding 130g of edible oil, 50g of onion, 40g of sugar, and 5g of salt, would improve the quality and overall acceptability of the dressing.

The change of three different reagents for electrical conductive paint using aircraft coating with elapsing time of exposure to different condition was investigated. Three different reagents were poured into the vial bottles, stored in air condition and room temperature and observed with elapsing days. In addition, adhesion property of paint was tried using cross cut tape test after storage of $N_2$ atmosphere. The weight of each different reagent was measured along with elapsing time. To confirm the change of chemical component with exposure of air atmosphere, FT-IR was performed. The weight of part A and Part B decreased slightly whereas the weight of part C decreased rapidly and the precipitation was remained. The part B was cured after exposure of $N_2$ atmosphere and the 2250 cm-1 from FT-IR peak decreased slowly at the same time. It was considered that the water contained in air accelerated the reaction of -NCO functional groups and it caused the curing whereas $N_2$ atmosphere not contained water and it resulted in the retardancy of curing.

A new and efficient method is presented to evaluate contact force and motion of an electric railway simple catenary-pantograph system. Overhead lines are regarded as simple strings, and hangers connected to the strings are replaced with concentrated forces acting on them. The displacement of strings due to concentrated forces caused by hangers and pantograph is expressed using Green's function. A system of linear algebraic equations in terms of unknown forces is derived based upon the compatibility requirement at the location of hangers and pantograph. This procedure is more analytic in formulation compared to the existing methods such as finite difference method or normal modes method, and it is expected to be more accurate. Present method has additional advantage that it requires neither numerical differentiation nor system eigenvalues.

The purpose of this study was to study on the estimation of green remodeling energy reduction tool in building construction. Green Remodeling Decision System that can predict the energy reduction effect in green remodeling is developed as a tool for simple remodeling of green remodeling considering users' convenience, so that it can quickly and comprehensively determine power peak load reduction factor technology. A preliminary simulation result of a short preliminary remodeling evaluation is DB. It will be developed as a tool that can be easily accessed by users such as web and apps.

In order to promote the growth of the trees, it is the most important to fertilize efficiently. The organic nutrient "Green-one" which list public notification number 08-organic-3-112" was registered in Rural Development Administration. The "Green-one" is the environment friendly organic nutrient with new concept which is used in planting and maintenance of the trees. The "Green-one" makes the tree grow actively. Also it has a function of the anti germ and sustainable fertilizer effect. In conclusion, "Green-one" promoted the growth of P. thunbergii excellently. Expecially the growth of the root increased. The concentration of "Green-one" dilution was more better 100 times than 300 times in trees grow. This research can apply with the test of fertilizer efficiency in landscape trees.

"Olgreen" (Scale cereal L.), a new rye variety was developed by National Institute of Crop Science(NICS), RDA. It was released in 2008 because of its high biomass yield potential and early maturity. It was developed from an open pollination within 10 rye varieties or lines including "Chochun" in 1995. The line 'SR95POP-S1-1072-1-2-4' was selected for its early maturity and excellent agronomic appearance, and placed in yield trials for two years from 2004 to 2005. It was designated "Homil 38" and placed in regional yield trials at the four locations around Korea from 2006 to 2008, from which the name "Olgreen" was given. Over three years, "Olgreen" averaged 8.88 ton ha-1 of forage yield (based on dry matter) harvested at late April and superior to other varieties with an increase of 10% more than the check variety "Olhomil", and 9% more than the introduced rye "Koolgrazer". Heading date of "Olgreen" was April 20 which was 3 days earlier than that of "Olhomil". It would be recommended as an early rye variety for forage or green manure in South Korea.

A compact representation of Green function is proposed by applying the discrete wavelet concept in the k-domain, which can be used for the acceleration of scattered field calculations in integral equation methods. Since the representation of Green function is very compact in the joint spatio-spectral domain, it can be effectively utilized in the fast computation of radiation integral of electromagnetic problems. A mathematical expression of Green function based on the discrete wavelet concept is derived and its characteristics are discussed.

Purpose: Since 2010, many universities in Korea have been implementing Green Leader Training Programs which are usually run by students themselves. In the last five years of 2015, the Green Leader Training Program under the sponsorship of Korean Association for Green Campus Initiative has promoted the practice of a green campus and many relative projects have been carried out in various fields. Method: We utilized the green campus component index established by the Presidential Committee on Green Growth in Korea and have analyzed 480 activities during the years of 2010~2015. Result: We found that many activities were classified into the environmental field(264, 55.0%). This was followed by university members' participation(130, 27.1%), community engagement(68, 14.2%), and university management(18, 3.7%). These results showed that the green campus initiatives were focused on the environmental field. The number of universities participating from 2010 to 2015 were 20 in the metropolitan area and 15 in the non-metropolitan are. In the metropolitan area, 81.7% of green leader activities were conducted at universities in Seoul, and those in non-capital areas were active in the Middle region(51.3%) and Yeongnam region(48.7%). On the other hand, there was no activity in the Honam region, and it shows that there was a noticeable differential by regional groups.

An efficient method of moments(MoM), which can lead to the analytical evaluation of the matrix elements, is proposed to analyze microstrip structures. The present method is formulated in conjunction with use of a new closed-form spatial-domain Green's functions which are derived by use of the integral formula for semi-infinite integrals of Bessel functions. It is observed that the computational efficiency such as the amount of calculation and computation speed has been improved due to the present MoM scheme by a factor of about 4 in comparison with the previous method. To validate the proposed method, several numerical examples are presented.
