  • Rice blast caused by the filamentous fungus Magnaporthe oryzae, is arguably the most devastating rice disease worldwide. Development of a high-throughput and reliable field blast resistance evaluation system is essential for resistant germplasm screening, resistance genes identification and resistant varieties breeding. However, the occurrence of rice blast in paddy field is easily affected by various factors, particularly lack of sufficient inoculum, which always leads to the non-uniform occurrence and reduced disease severity. Here, we described a procedure for adequately inducing the occurrence of rice seedling blast in paddy field, which involves pretreatment of diseased straw, initiation of seedling blast for the first batch of spreader population, inducing the occurrence of the second batch of spreader population and test materials. This procedure enables uniform and consistent infection, which facilitates efficient and accurate assessment of seedling blast resistance for diverse rice materials.

  • Product liability (PL), which began enforcement in 2002, refers to the legal responsibility of the manufacturers or sellers (wholesales or retailers) for the property damage or bodily harm caused by their product. With a strong enforcement of the Product Liability (PL) Act, companies are required to structure and operate a response system to defend or prevent product accidents efficiently, but small and medium enterprises (SMEs) are unable to respond more aggressively due to limitation of management resources. In this manner, it is important to develop response strategies for SMEs to efficiently cope with the PL Act. In this paper, the PEST (Political, Economic, Social, and Technological) analysis is performed to reveal the impact of the PL Act on SMEs in macro-economic point of view. To formulate SME's PL response strategy, SWOT analysis is performed to categorize each factors from PEST analysis and AHP is applied to identify the intensities of SWOT factors. The prioritized SWOT factor, results of PEST-SWOT-AHP analysis, are used to formulate SME's PL response strategies. The study results are briefly summarized as follows. To reduce product defects, it is necessary for SMEs to formulate PL response strategies for each phase of the product life cycle by continuously collecting and analyzing PL cases in the same industry or for similar products. In addition, SMEs should invest more technological effort to ensure product safety. Further, SMEs should spread PL awareness to all staff members by training internal PL experts. Moreover, a SME should enroll in PL insurance and spread this information to its customers so that they become aware that the company is proactively conforming to the PL law.

  • A decrease in pass ratio of Korean exporting pears causes several negative effects including an increase in pesticide dependency. In this study, we attempted to establish the pest forecasting management system, composed of weekly field forecasting by pear farmers, meteorological data obtained by automatic weather station (AWS), newly designed internet web page ($\underline{http://pearpest.jnu.ac.kr/}$) as information collecting and providing ground, and information providing service. The weekly field forecasting information on major pear diseases and pests was collected from the forecasting team composed of five team leaders from each pear exporting complex. Further, an abridged weather information for the prediction of an infestation of major disease (pear scab) and pest (pear psylla and scale species) was obtained from an AWS installed at Bonghwang in Naju City. Such information was then promptly uploaded on the web page and also publicized to the pear famers specializing in export. We hope this pest forecasting management system increases the pass ratio of Korean exporting pears throughout establishment of famer-oriented forecasting, inspiring famers' effort for the prevention and forecasting of diseases and pests occurring at pear orchards.

  • Over the past decade, double-stranded RNA (dsRNA)-mediated gene silencing technology has progressed significantly for pest management in agriculture and for protecting beneficial insects from pathogens. Recently, breakthroughs in RNA interference (RNAi) applications for insect pest management by academia and commercial entities have provided RNAi products as commercial biopesticides. Although RNAi technology has vast potential and advantages for pest control, challenges, and limitations remain in practical applications. This review explores current challenges in the development of dsRNAs as a pest management tool and considers new approaches to overcome biological and environmental obstacles, such as poor stability and resistance.

  • Science and technology(S&T) are not only advancing, but also the number of stakeholders in those fields are increasing, and so the demands of S&T strategy for a particular field are increasing. In Korea, especially, this tendency is remarkable, and is evidenced by the fact that more than one hundred of S&T strategies have been established and implemented. However, academic attempts to clarify scientific methodologies for establishing S&T strategy have so far been rare. In this paper, a methodology to establish S&T strategies in a particular field is proposed and examined through a case study to determine its usefulness. First, through an analysis of the literature, previous studies on the establishment of a national S&T strategy and its related concepts are reviewed. Also, a representative framework plans, in accordance with relevant legislation and regulations, are reviewed. Meanwhile, the methodology, PEST-SWOT-AHP, is proposed and the features and applications are identified. For the case study, the strategy establishment of a fusion research and development program is performed. In order to apply the PEST-SWOT-AHP tool, an environmental analysis based on the fusion R&D roadmap is conducted. To examine the usefulness of the proposed framework, a national fusion R&D strategy applying PEST-SWOT-AHP is derived. As a result of the case study, four strategies were derived. Those are be the first mover, promotion of basic research and cultivation of manpower, boost commercialization and public acceptance and reinforcing international cooperation.

  • In this study, insect pest communities and major insect pest species were investigated and compared among 30 cultivars of Hibiscus syriacus. Insects on H. syriacus were observed with the naked eye over 3 years (from 2018 to 2020) in Busan and Suwon. Except for Aphis gossypii (79,059 and 23,654 individuals in Busan and Suwon, respectively), 20 species (1,147 individuals) and 31 species (2,240 individuals) were found in Busan and Suwon, respectively. The number of insect pest species and individuals did not differ among H. syriacus cultivars, but there were differences according to study locations. The dominant insect pest species were A. gossypii, Rehimena surusalis, Rusicada privata, Halyomorpha halys, Haritalodes derogata, Dolycoris baccarum, and Plautia stali; the number of individuals in dominant species differed according to study location and year but not among H. syriacus cultivars. In summary, insect pest communities did not differ among 30 H. syriacus cultivars, but the matrix of surrounding environments where H. syriacus are planted may be more important.
