Profitability of farmers has decreased mainly owing to low price while the gross amount of mushroom production has increased continuously in South Korea. In this regard, analyzing patterns of mushroom consumption is believed to be meaningful. We used a panel data set consisting of 667 families, from 2010 to 2015. Based on the panel data, mushroom consumption patterns of people living in city areas were examined. Multiple descriptive analysis methods and frequency analysis approaches were adopted in this study in terms of time and space dimensions, demographic properties, and purchase behaviors. The findings of this studyshow that mushroom purchase is highly dependent on seasonal events, which implies that the product consumption timing is predictable. In addition, yearly purchase amount patterns reflect that superstores have become the major mushroomtrading venues. This directly supports the need to establish supply chain capabilities for mushroom farmers so that they gain more bargaining power against enterprise-type groceries. Finally, functional features of mushroom can be linked with marketing promotion because purchase patterns demonstrate potential needs for healthcare food in mushroom categories. Based on the analyzed patterns, this paper provides insightful implications for policy makers who want to promote mushroom consumption.

To determine sugars content of agricultural products and foods, simultaneous quantitative analysis was carried out on fructose, glucose, sucrose, maltose, and lactose by HPLC-RI. Analysis conditions were set as column ZORBAX carbohydrate (4.6 mm ID×250 mm, 5 μm), the mobile phase of 75% ACN, the column temperature of 35oC, sample injection amount of 10 μL and the flow rate of 1 mL/min. Five standard solutions were isolated without interfering peak within 30 minutes and the calibration curves of standard were confirmed excellent linearity from 0.10% to 1.00% with R2≥0.999. Based on the chromatogram of the standard solution, the limit of quantification (LOQ) and the limit of detection (LOD) values were calculated. The accuracy of the analytical values were highest at 100% water extraction method to the fructose 95.7%, sucrose 98.7%, lactose 102.7% respectively, compared with reference value of a certified reference material (BCR644), by applying the four solvent extraction methods. Using an in-house quality control material (infant formula), repeatability and reproducibility values of this experiment were verified on the basis of AOAC guideline and reference values were set up at 1.17 g/100g of glucose, 0.85 g/100g of maltose, and 45.54 g/100g of lactose. Quality control charts were drawn up and used for sugars analysis of agricultural products.

본 연구는 접목선인장 비모란(Gymnocalycium mihanovichii var. friedrichii)의 무배지 수경재배에 이용되는생력트레이의 적합한 형태를 구명하고자 수행하였다. 높이를 8, 13, 18, 23mm로 조정한 생력트레이의 관수공 존재 여부에 따른 시험처리 결과는 다음과 같다.관수공이 있는 경우, 중형규격 접목선인장의 구직경, 구고 및 생체중은 생력트레이의 높이가 8mm와 13mm에서 다른 처리보다 증가하였으나, 18mm 이상으로 높아지면 생육이 감소되었다. 그러나, 관수공이 없는 경우 8, 13, 18mm 높이의 생력트레이에서 중형규격 접목선인장의 구직경, 구고, 접수생체중이 크고 자구수가많았으나, 23mm 높이의 생력트레이는 다른 처리에 비해 접수 생육이 감소되었다. 관수공이 있는 생력트레이를 사용한 대형규격 접목선인장의 구고는 8mm와13mm 높이에서 접수생체중은 8~18mm 높이에서 컸던 반면에 관수공이 없는 생력트레이는 높이에 따른접수의 생육 차이가 없었다. 중형규격 접목선인장의경우 상품화율은 8, 13, 18mm 높이의 생력트레이가23mm에 비해 높았는데, 뿌리건물중은 23mm 높이의생력트레이에서 가장 무거웠다. 반면 대형규격 접목선인장의 경우는 관수공이 없는 생력트레이는 높이에 관계없이 상품화율이 높았으나 뿌리건물중은 23mm에서높았다. 또한 관수공이 없는 경우 생력트레이 하부에뿌리가 균일하게 분포되며 트레이의 높이가 높아지면뿌리가 분포할 수 있는 공간이 넓어질 수 있으므로 관수공이 없는 높이 18mm 정도의 트레이가 접목선인장무배지 수경재배에 적합한 형태인 것으로 판단되었다.

In recent years, various policies have been conducted for the activation of the value chain for 6th industrialization of agriculture, which is aligned with creating job opportunities and start-up as well as value added enhancement. For this reason, this study seeks measures to kick-start application and development of a model to raise the success rate of startups and reduce the risk of market throughout surveying 168 6th industrialization management bodies about their start-up and business, and benchmarking of best practices, a case consistent with the value chain system of 6th industrialization of agriculture. Main findings are three-folds: First, it is necessary to raise the success rate of startups by means of the compatibility of the capital scale, low cost and life cycle of ideas. Second, the living lab for sharing ideas and collaboration is needed in the value chain system. Third, the living lab model is promoting rural community development and farm household income.
