There are lots of buildings which were built before the Legislation on building energy rating system. Remodeling of the buildings would be required for an improvement of the building energy rating system was enforced by the government. In the Passive Building Design, Elements which will be used for the remodeling are Insulation, Window, External venetian blind, Heat exchanger. The Purpose of this study is to indicate a Method for the improvement of Energy saving by an analysis of Construction Cost, Cost Evaluation, Energy performance Efficiency in applied design elements. In this study, the remodeling of existing public buildings to improve energy efficiency rating was applied to extract the elements of design-specific energy performance, efficiency, and the application of the designs that has been analyzed. The results were as follows: applying the design-specific cost-effective investment that represents the economy (investment efficiency/%) surveyed the average insulation(7.0%), triple glazed windows(10.1%), double glazed windows(12.1%), external shading(24.5%), and Heat(77.2%) were analyzed in order to be more efficient. Analysis of the basis of information on the existing public buildings to improve energy efficiency rating for the remodeling depending on driving conditions at a degree of individual difference. The main effect, however, depending on economic investment, design elements, heat exchangers, external awning, double glazed windows, triple glazed windows, insulation, is recommended as review of the order shall be determined.

In recent years, the temperature of Korea has been rapidly increasing due to global warming. Over the past 40 years, the temperature of Korea has risen by about 1.26℃ compared to that in the early 1980s. By region, the west region of the Gangwon Province was the highest at 1.76℃ and the Jeonnam Province was the lowest at 0.96℃. As the temperature continues to rise, it is expected that the rice yield will decrease in the future using the current standard cultivation method. As a result of global warming, the periods in which rice cultivation could be possible in regions each year has increased compared those to the past, showing a wide variety from 110 days in Taebaek to 180 days in Busan and Gwangyang. In addition, the transplanting time was delayed by 3-5 days in all regions. The average annual yield of rice showed an increasing trend when we analyzed the average productivities of developed varieties for cooked rice since the 1980s, especially in the early 1990s, which showed a rapid increase in productivity. The relationship between the average temperature at the time of development and the rice yield was divided into the periods before and after 1996. The higher the average temperature, the lower the yield of the developed varieties until 1996. However, since 1996, the increase in the average temperature did not show a trend in the productivity of the developed varieties. The climate change adaptability of developed rice varieties was investigated by analyzing the results of growing crops nationwide from 1999 to 2016 and the change in the annual yields of developed varieties and recently developed varieties as basic data to investigate the growth status of the crops in the country. As a result of annual comparisons of the yields of Taebongbyeo (2000) and Ungwangbyeo (2004) developed in the early 2000s for Odaebyeo, which was developed in the 1980s, the annual yields were relatively higher in varieties in the 2000s despite the increase in temperature. The annual yields of Samgwangbyeo (2003) and Saenuribyeo (2007), which were recently developed as mid-late-type varieties, were higher than those of an earlier developed variety called Chucheongbyeo, which was developed in the 1970s. Despite the rapid increase in temperature, rice cultivation technology and variety development are well adapted to climate change. However, since the biological potential of rice could reach its limit, it is necessary to develop continuous response technology.

작물 재배기간 토양 탄소의 대부분은 유기물로 존재하며 토양양분 공급, 토양물리성 개선 등 중요한 역할을 한다. 또한 토양에 탄소를 저장하여 기후변화에 따른 온실가스 감축에 역할을 하여 그 역할이 더욱 더 중요해지고 있다. 토양탄소의 축적은 단기간 이루어지지 않고 장기간에 걸쳐 이루어 지기 때문에 이와 관련한 기초자료가 중요하다. 본 연구에서는 벼 재배 조건에서 7년간 볏짚, 헤어리베치, 가축분퇴비, 유박을 연용하였을 때 토양 탄소의 변화를 평가하였다. 초기 토양의 탄소함량은 7.9이었으며 볏짚을 연용하였을 경우 서서히 증가하여 11.5, 헤어리베치는 11.6, 가축분퇴비는 15.9 및 유박은 11.6 g/kg으로 증가하였다. 그러나 유기물의 투입량에 따라 증가속도는 차이가 있었으며 가축분 퇴비가 토양탄소 축적에 가장 적합한 것으로 평가되었다. 토양탄소 유기물 형태를 풀빅산, 휴믹산, 휴민으로 구분하여 평가한 결과 세가지 형태의 변화는 일정 범위에서 변동성을 가지며 증가 또는 감소 추세는 보이지 않았다. 지난 7년간의 유기물 연용에 따른 토양탄소의 변화량을 보았을 때 토양탄소의 중장기적 축적을 위해서는 퇴비의 시용이 필요하며 유기물의 연용을 통한 유기물 축적과 분해의 연차간 수지를 조절하는 것이 무엇보다 중요한 것으로 판단된다. 따라서 본 연구결과는 향후 토양탄소 축적을 위한 토양관리 방법을 제시하는데 중요한 기초자료로 활용될 수 있을 것이다.

The global area of GM Crops continued to grow in 2018 and reached 191.7 million hectares. Twenty-six countries approved biotech crops for planting and an additional 44 countries (18 + 26 EU countries) officially imported biotech crops for food, feed, and processing, meaning that biotech crops are now commonly accepted in those countries. First-generation GM seed is being commercialized by global agricultural companies in advanced countries such as the United States and parts of Europe. The fact that more than 90% of first-generation GM seeds, which have been commercialized for 20 years, are both insect resistant and herbicide resistant proves that they continue to have an effect on improving agricultural productivity and increasing farmers incomes. As the effectiveness of GM crops has been proven and technology has been developed, the GM crop development trend has recently changed. In other words, it has moved from being producer-oriented to benefiting both farmers and consumers. In Korea, the National Program for GM Crops (NCGC), one of the Next-Generation BioGreen 21 Programs organized by Rural Development Administration (RDA), was established in 2011 to develop biotech crops that will be used in the future to solve our agricultural problems. To accomplish this mission, the NCGC carried out the exploration of useful functional genes, the development of qualified events, and the safety assessment of developed events. Here, we introduce the current status of GM crop development and commercialization in the world and in Korea.

농업 분야에 디지털 기술의 융복합 연구 및 실용화가 활발하게 이루어지고 있으며 미래에는 활용도가 더욱 높아질 전망이다. 작물의 생육 분석과 관련하여 영상, IoT 등의 하드웨어와 AI, 컴퓨터비전 등의 소프트웨어가 결합한 기술이 유망하며 특히 ToF(Time of Flight) 등과 같은 깊이 센서의 활용을 주목할 필요가 있다. 본 연구에서는 깊이센서 카메라(MS kinect)를 활용하여 옥수수 포장에서 옥수수 생육에 따른 군락 초장을 측정하기 위한 방법을 개발하였다. 시험에 사용된 옥수수 품종은 광평옥과 일미찰을 이용하였으며 센서는 MS Azure kinect를 사용하여 3m, 5m 직각 위치에서 1시간 간격으로 depth와 RGB 촬영을 하였으며 point cloud 소프트웨어 등을 이용하여 분석을 실시하였다. 입체 데이터와 RGB 영상을 정합하여 일사에 의한 방해가 최소화된 시간인 촬영된 날짜의 5-6시, 7-8시의 영상을 대상으로 각 영상별 직접 20점씩 포인트를 지정하여 수동으로 초장을 측정하였으며 영상에서 Z 값에 대한 이상 데이터를 제거하고 상위 1%, 10%의 값을 추출하여 초장 분석을 하여 상호비교를 수행하였다. 초장은 수동으로 측정한 결과값과 상위 1%에서 측정한 값과 매우 높은 상관관계를 나타내어 군락의 생육상황을 상당히 정확하게 표현할 수 있었다. 또한 RGB 영상의 분할을 통한 군락 엽면적을 평가한 결과도 군락 비율이 약 80~90%까지는 생육과정을 표현할 수 있었다. 본 연구결과 깊이 센서와 RGB 영상을 활용할 경우 초장, 엽면적 및 바이오매스까지도 추정한 보정계수를 확보하여 기존의 인력에 의한 수동 측정방법을 대체할 수 있을 것으로 기대되었다.

Global GM crops continue to grow. They have reached 181 million hectares. A total of 28 countries have approved biotech crops for planting. More than 60 countries have approved biotech crops to be imported as food and feed since 1996, meaning that biotech crops are now commonly accepted in those countries. Although biotech crops provide key solutions for the challenge of global food security in the future due to population growth and climate change, there are still some debates on whether biotech crops should be accepted in many countries including Korea. Therefore, it is very important to make people understand that GM crops will provide benefits to both farmers and consumers. In this review, current global status of GM crop development and commercialization are summarized.
