Quality sorting of cut flowers is very essential to increase the value of products. There are many factors that determine the quality of cut flowers such as length, thickness, and straightness of stem, and color and maturity of bud. Among these factors, the straightness of stem and the maturity of bud are generally considered to be more difficult to evaluate. A prototype grading and sorting machine for cut flowers was developed and tested for a rose variety. The machine consisted of a chain-drive feed mechanism, a pneumatic discharge system, and a grading system utilizing color image processing and neural network. Artificial neural network algorithm was utilized to grade cut roses based on the straightness of stem and maturity of bud. Test results showed 89% agreement with human expert for the straightness of stem and 90% agreement for the maturity of bud. Average processing time for evaluating straightness of the stem and maturity of the bud were 1.01 and 0.44 second, respectively. Application of neural network eliminated difficulties in determining criteria of each grade category while maintaining similar level of classification error.

Novel, effective methods to control and prevent spoilage and contamination by pathogenic microorganisms in meat and meat products are in constant demand. Non-thermal pasteurization is an ideal method for the preservation of meat and meat products because it does not use heat during the pasteurization process. Atmospheric pressure cold plasma (APCP) is a new technology for the non-thermal pasteurization of meat and meat products. Several recent studies have shown that APCP treatment reduces the number of pathogenic microorganisms in meat and meat products. Furthermore, APCP treatment can be used to generate nitrite, which is an essential component of the curing process. Here, we introduce the effectiveness of APCP treatment as a pasteurization method and/or curing process for use in the meat and meat product processing industry.

The Elfvingia applanata (EA), Hericium erinaceum (HE), Grifola frondosa (GF), Pholiota nameko (PN), Pleurotus eryngii (PE), Trametes suaveolens (TS), Fomes fomentarius (FF), and Inonotus obliquus (IO) could produce the endo- (EN) and exo-biopolymer (EX) in submerged culture. The highest anti-complementary activity of the EN was exhibited by PN (49.1%), followed by HE (38.6%), TS (37.0%), and FF (33.0%), whereas the high activity of the EX was found with GF (59.8%), followed by HE (36.3%), TS (30.8%), and IO (28.8%). The EN of P. nameko (EN-PN) and EX of G. frondosa (EX-GF) were found to contain 78.6% and 41.2% carbohydrates, while 21.4% and 58.8% protein, respectively. The sugar and amino acid compositions of EN-PN and EX-GF were also analyzed in detail.

This study was focused on analyzing the impacts of e-commerce on the farmer's management behavior and suggesting alternatives for the development of e-commerce in agricultural industry. For this study, survey was conducted for 24 farmers who sell agricultural products through e-commerce in Chungnam province. The results of study are as follows; First, farmers have changed their management practices in terms of production, marketing and processing by using the information of consumers' preferences while doing e-commerce business. Second, farmers have attempted to differentiate their product through product brand and customer relationship marketing, because they recognized the importance of developing marketing techniques adapted to e-commerce system for more revenues. Third, if quality certification system of agricultural products is introduced under e-commerce, farmers would use it for their environmentally sounded farming because they expect to increase their income. Fourth, 75% of the farmers sold their product at retail price. It means that e-commerce farmers act as a price maker rather than price taker at e-commerce market, who will be encouraged to have larger business size resulting in more added value. Based on the results of study, we suggest that there should be reduction of service charge for credit card, and encouragement of B2B transaction for the economy of scale and introduction of quality certification system so as to establish e-commerce system of agricultural industry as soon as possible.

Due to the rapid evolution of high-throughput technologies, a tremendous amount of data is being produced in the biological domain, which poses a challenging task for information extraction and natural language understanding. Biological named entity recognition (NER) and named entity normalisation (NEN) are two common tasks aiming at identifying and linking biologically important entities such as genes or gene products mentioned in the literature to biological databases. In this paper, we present an updated version of OryzaGP, a gene and protein dataset for rice species created to help natural language processing (NLP) tools in processing NER and NEN tasks. To create the dataset, we selected more than 15,000 abstracts associated with articles previously curated for rice genes. We developed four dictionaries of gene and protein names associated with database identifiers. We used these dictionaries to annotate the dataset. We also annotated the dataset using pretrained NLP models. Finally, we analysed the annotation results and discussed how to improve OryzaGP.

국내에 수입되어 판매되는 해외식품 수입액은 매년 급증하는 추세이며, 원재료를 수입하여 가공하는 것을 포함하면 규모는 더 클 것으로 예상된다. 수입 농수산물 완제품에 대한 화물신고 시 원재료에 대한 원산지는 표기되나, 원재료에 대한 검사 정보는 아직 미흡한 편이다. 이에 농수산물 제품 구매 시 원재료 또는 제품에 남아 있는 방사능 존재 여부, 생산 이력 관리 등에 대한 우려가 커지고 있다. 국내 수입농수산물의 위해식품정보는 관리되고 있으나, 미생물, 잔류농약, 식품첨가물, 알레르기 성분 등 주로 글로벌 이슈가 되는 위해요소들이 대부분이다. 그러므로 원재료의 생산이력 및 검사정보의 체계적인 관리를 위해서는 전체 운송과정에서의 물류 주체들 간 관련 데이터의 공유와 활용도 제고를 위한 아키텍처, 비즈니스 모델 등에 대한 표준화가 필요하다고 판단된다. 이에 본 논문에서는 수입농수산물 운송 중 상태 추적을 위해 단계별 정보를 수집, 가공, 처리하기 위한 아키텍처를 설계하고, 비즈니스 프로세스 간에 발생하는 업무 흐름을 정의하였다. 또한 도출한 데이터 엘리먼트로 정보 모델을 정의하고 UBL 기반의 XML 스키마를 정의하였다. 제안한 표준 모델을 통해 물류 주체 간 정보 유통 및 공유가 용이할 것이며, 실시간 관리가 필요한 농수산물 운송에 대한 가시성, 신뢰성, 안전성 및 신선도 체계 수립이 가능할 것으로 기대한다.

Agricultural extension services in YoungDong county, ChungBuk province have tried and changed many things to overcome difficult situations since localization of extension services in 1997. The county Rural Guidance Office changed the name of the office as county Agricultural Technology & Extension Center (ATEC), and has been operated as a service center for all people who need help in agriculture. The recent efforts of the ATEC have been placed on eco-friendly agriculture and sustainable agriculture for protecting the natural environment of the county as well as production of safe agricultural products. In order to overcame difficult situations under the IMF, the ATEC has tried to find new ways for the extension services because of reduced extension educators under the IMF restructuring. The followings were a few examples of many efforts in various fields to overcome difficult situations in the rural county; 1) The ATEC has supported services to produce safe and high quality agricultural products and to increase their high value through extension services for food processing. 2) The ATEC has opened experimental fields for farmers who want to learn new technologies to cultivate grapes, persimmons, apples and pests etc., specialty fruit trees in the county. 3) The ATEC has implemented many kinds of programs to improve the quality of the extension educators to serve better.
