Eco-efficiency which is calculated by dividing economic productivity by the environmental load was made by synthesizing eco and efficiency from ecology and economy, proposed by World Business Council for Sustainable Development in 2000. Eco-efficiency by connection of resource efficiency with resource intensity is used as an indicator for evaluating green growth for minimizing the impact on the environment and achieving economic development as well by means of efficient use of resources. This research analyzes eco-efficiency with the case of organic agriculture promoted as a key green growth policy. Thirty questionnaires for farmers producing organic rice in Hongseong-gun, Choongcheongnam-do were used for the analysis. Eco-efficiency was measured by means of the amount of used nitrogen with respect to the amount of income, and was represented that organic agriculture was 32.0 higher than conventional agriculture. The analytical result of technical efficiency, using the (Data Envelopment Analysis (DEA) model showed that it is 0.765 which has a possibility of 21% in management improvement, and higher eco-efficiency was with higher technical efficiency. The analytical results showed that an organic agriculture contributes to green growth more than conventional agriculture. In addition, higher technical efficiency groups exhibited higher eco-efficiency indices.

This study was conducted to survey some characteristics in growth of perilla by fertilization level organic matter. Corn stalk, acorn and chestnut were used as organic fertilizer in this study. In the height of perilla, chestnut fertilizer with 880kg/10a that R2 is 0.9996 showed the height level, and followed by acorn and corn stalk in order. Number of the harvested leaves was the highest in acorn among the three organic fertilizer by chestnut and corn stalk in order. However, number of the harvested leaves continuously was the highest in chestnut. Weight of a leaf was more effective at three kinds of organic fertilizer than control. There were no difference in the rate of dried leaf weight according to kinds of organic fertilizer. On the other hand, the rate of dried leaf weight by growth period was different. It was found that the rate of dried leaf in 30days or 110days. Diameter of perilla stem at 30cm above the ground according to kinds and fertilizer level of organic fertilizer was surveyed. However, the difference was not detected in this study.

This study explores the development process of an farmers' group in Asan City that now plays an important role in the development of organic farming of the region. While increase in income in general may be one of main purposes making farmers join or form a group, the farmers group in Asan, instead, has tried to form a cooperative of local organic farmers. In doing so, they experienced a lot of difficulties and leant by trial and error. As a result, the farmers' group has recently developed in terms of business and organisational growth. The growth is not merely due to the growth of organic food markets but also due to the strong internal ties and trust that made possible to expand into food processing as well as to do social and cultural activities fur the rural residents. It implies that trust and cooperative identity between farmers should be the most important thing to be locally embedded farmers groups in a specific region.

This experiment was conducted to study the effect of organic fertilizer on the growth of Peucedanum japonicum Thunberg and the change of soil chemical characteristics. The organic matter contents of coffee sludge and dried food waste powder were 44.26 and 51.18%, respectively. These values exceed the organic matter content of organic fertilizers recommended by the Rural Development Administration (RDA) of South Korea by more than 30%. Accordingly, they indicate the possibility of their use as organic fertilizers. The results from the analysis of soil properties after cultivation showed that the organic matter content of coffee sludge amended soils was two-fold higher than that of dried food waste powder amended soils. However, the content of available phosphorus was two times lower in the coffee sludge amendments. It is expected that the dried food waste powder was actively used to decompose organic substances, and that phosphoric acid was added by the soil microorganisms used to decompose organic substances. In terms of Peucedanum japonicum Thunberg growth, leaf discoloration was observed for all treatments except with the standard rate of dried food waste powder. The standard rate of dried food waste powder also produced relatively better results than other treatments with regard to other growth characteristics such as root length (34.08 cm), root diameter (0.78 cm), and fresh root weight (4.77 g plant^-1). Therefore, the standard rate of dried food waste powder produced better results than other treatments and can be used as an organic fertilizer in the growth of Peucedanum japonicum Thunberg.

기업의 성장동력 전략으로 내부 개발역량에 의존하는 자생적/유기적(Organic Growth) 방식과 전략적 제휴나 인수/합병을 통해 외부 자원을 활용하는 비유기적 성장(Inorganic Growth) 방식을 나눌수 있다. 하지만 이러한 혁신전략 안에는 성공과 실패가 공존하고 있으며 특히 최근에는 조직내 혁신을 달성하기 위해 연구 및 개발, 상용화에 이르기까지 혁신 과정을 개방하여, 외부 자원을 적극활용함으로써 혁신의 비용을 줄이고 성공가능성을 높여 부가가치 창출을 극대화하는 혁신활동중 하나로 개방형혁신(Open innovation)을 많이 활용 하고 있다. 하지만 더 나아가 사업의 지속 가능한 성장을 위해서는 External Organic Innovation을 같이 활용하는 새로운 혁신전략 활동 전개가 필요하다. 그래서 본 연구에서는 이러한 혁신 전략들의 성공-실패 사례분석을 통해 4차 산업혁명시대에 맞는 혁신전략을 살펴보고자 한다.

The genus Paxillus is characterized by the difficulty of species identification, which results in reproducibility problems, as well as the need for large quantities of fungal inoculum. In particular, studies of Paxillus ammoniavirescens have reported divergent results in the in vitro growth while little is known of its capacity to degrade organic matter. For all the above, and assuming that this variability could be due to an inappropriate culture media, the aim of this study was to analyse growth in different culture media (MMN, MS, and 1/2 MS) and in the case of MMN in presence/absence of two types of organic matter (fresh litter and senescence litter) to probe the saprophytic ability of P. ammoniavirescens. We also evaluated the effects of pH changes in the culture media. Growth kinetics was assessed by weekly quantification of the area of growth in solid culture media over 5 wk, calculating the growth curves and inflection points of each culture media. In addition, final biomass after 5 wk in the different culture media was calculated. Results showed that best culture media are MS and 1/2 MS. Moreover, an improvement in growth in culture media containing decomposing fall litter was observed, leading to confirm differences in the culture media of this species with others of the same genus. Further, we established that all growth media suffered a significant acidification after fungal growth.

It is well known that bioassay on the low organic matters in water have developed from the two methods. One is assimilable organic carbon(AOC) that makes use of the maximum growth biomass of the pure strains for the standard substrates, the other is biodegradable dissolved organic carbon(BDOC) that determines the fraction of dissolved organic carbon(DOC) available for microbial utilization. The purpose of this study was to upgrade the measurement method of BDOC in natural water or drinking water. BBOC was determined by means of the bacterial growth and the DOC decrease at the same time. The origin inoculums were used to the suspended bacteria from Han River water, The initial optimum biomass and incubation time for initial DOC were induced by variation of nutrient repression and inoculums. The time reached to minimum DOC was selected as incubation time. The initial optimum biomass for Han river water was about 1000~5000 CFU/mL, respectively. In a sufficient biomass, suitable incubation time was about 3~5 day. It was indirectly calculated BDOC on maximum growth rate by measuring growth yield of indigenous bacteria. But it was difficult to adapt growth yield coefficient because of irregular bacterial growth. The measured 3 day BDOC was close to BDOC calculated with our proposed experimental equation between DOC and BDOC. It shows that the quantification of BDOC with this experimental equation can be used indirectly.

Organic farming has rapidly increased in Gangwon province, but there is a concern about nutrient accumulation and nutrient imbalance in the soil of organic farming. This study was conducted to investigate the impact of continuous application of organic amendments on growth and yield of red pepper and soil characteristics compared with chemical fertilizers application for four years. Treatments of organic amendments including oil cake, rice straw compost, amino acid compost, rice bran compost, and mushroom media (spent substrate) compost resulted in comparable growth and yield of pepper to chemical fertilizers. Organic amendments improved soil physical and chemical characteristics. Especially, rice bran compost and oil cake significantly increased soil organic matter compared with chemical fertilizer application and mushroom media compost and rice straw compost significantly improved soil aggregate stability. On the other hand, available phosphate level in the soil amended with rice bran compost or mushroom media compost was relatively high compared with the other treatments due to relatively high phosphate levels in the composts. It is not easy to adjust nutrient composition in the organic materials. Therefore, the results obtained from the study imply that nutrient imbalance needs to be carefully considered in organic farming without use of chemical fertilizers.

유기상토에 툽밥 발효 돈분으로 생산한 분립의 첨가비율을 달리했을 때, 벼의 유식물체 생육에 미치는 영향을 조사하였다. 저면도포 무처리구에서 추청 벼는 분립 20%까지의 혼합비율, 흑미 벼는 분립 10%까지의 첨가비율에서 유식물체의 생육이 양호하였다. 또한 저면도포 처리구에서는 추청 벼와 흑미벼 모두 분립 5% 혼합비율에서 유식물체의 생육이 양호하였다. 저면도포 처리구가 무처리구에 비하여 낮은 분립 첨가비율에서 유식물체의 생육이 양호하였던 것은 뿌리신장에 의하여 토양표면에 시용된 분립으로부터 생육에 필요한 양분의 공급이 이루어졌기 때문으로 추정된다. 또한 장기간 벼를 육묘할 경우에는 유식물체의 생육이 양호하였던 분립의 적정 혼합비율의 범위가 갖는 상토의 이화학성의 유지가 필요하다고 판단된다. 지렁이 분립의 이화학적 특성으로 볼 때, 유기 경종농업에서 토양시용 또는 상토재의 원료로서 유용하게 활용될 수 있을 것으로 판단된다.
