  • 패션프루트(Passiflora edulis)는 브라질이 원산지이며 아열대와 열대지역에서 재배되고 있는 다년생 상록덩굴식물로 시계꽃과(Passifloraceae) 시계꽃속(Passiflora)에 속한다. 전 세계적으로 500여종이 분포하고 그 중 10여종은 식용, 나머지는 관상용으로 이용되고 있다. 지구온난화로 인한 기온상승으로 전남지역 재배에 적합한 대체 아열대과수 개발이 필요하다. 패션프루트는 겨울 최저온도가 $3^{\circ}C$이상 조건에서 재배 가능하여 남부 지역는 무가온 하우스재배를 하고 있지만 시설내 6월 하순부터 8월 중순까지 $35^{\circ}C$ 이상 고온이 지속되어 과실을 볼 수 없다. 8월 하순부터 피는 꽃은 인공수분으로 착과되어 11월부터 수확이 가능하지만 이후에 낮은 온도($10^{\circ}C$이하)로 착색이 진행되지 않아서 동해피해로 수확을 포기해야 한다. 어느 시기까지 인공수분을 해야 당년에 안정적인 수확이 가능한지를 알아보고자 패션프루트의 후기(2차) 개화시기 중에서 8월 30일, 9월 10일, 9월 20일, 9월 30일에 인공수분 하여 11월 하순에 착색이 정상적으로 진행되는 처리를 조사한 결과 8월 30일 처리구만 11월 21일 착색이 되었다. 미착색과에서 내용물이 진노랑색으로 진행되면 후숙하여 상품과로 판매가 가능하기 때문에 진노랑색에 도달한 시기를 조사하였다. 조사에서 9월 10일까지 인공수분 처리한 과실은 후숙하여 상품과로 판매가 가능하였다.

  • Toxicities of 51 pesticides (25 insecticides, 11, acaricides, 11 fungicides and 4 adjuvants) commonly used to control greenhouse insect, mite, and disease pests were evaluated to minute pirate bug, Orius strigicollis nymphs and adults at the recommended concentration. Among 25 insecticides tested, fipronil, lufenuron, acetamiprid+fipronil, $\alpha$-cypermethrin+flufenoxuron and buprofezin + amitraz showed low toxicity to O. strigicollis. Among acaricides, acequinocyl, bifenazate, chlorfenapyr, etoxazole, fenpyroximate, flufenoxuron, milbemectin, spirodiclofen and tebufenpyrad showed low toxicity to O. strigicollis. All fungicides and adjuvants tested were very low toxicity. It may be suggested from these results that five insecticides, nine acaricides, eleven fungicides and four adjuvants could be incorporated into the integrated thrips management system with O. strigicollis in greenhouses.

  • Insecticidal activity of 31 registered insecticides was tested against Metcalfa pruinosa adults. All experiments were conducted at the recommended concentration (ppm) of each insecticide. Among them, 16 insecticides from organophosphates (dichlorvos, fenitrothion, fenthion, methidathion, phenthoate), carbamates (methomyl), pyrethroids (${\alpha}$-cypemethrin, deltamethrin, fenpropathrin, ${\gamma}$-cyhalothrin), neonicotinoids (acetamiprid, clothianidin, dinotefuran, imidacloprid, thiamethoxam), and other (endosulfan) showed 100% mortality by spraying on the body of M. pruinosa adults. Dichlorvos, fenitrothion, fenthion, methidathion, phenthoate and endosulfan showed 100% mortality by plant-dipping method. The residual effect was showed 100% mortality in four insecticides (fenitrothion, fenthion, methidathion, phenthoate) at one day after treatment, and three insecticides (fenitrothion, methidathion, phenthoate) were showed the mortality of 90% at three days after treatment.

  • This study explores the possibility of innovative government's administrative services to the public by reflecting the social implications of 'Big Data'. In particular, the idea of OPP (Order Penetration Point) and SOP (Service Offering Point) as a management scheme for the extension of administrative processes into the resident's living space is proposed to overcome the inherent limits of e-government service quality, the root cause of which is believed in the segregation of two spaces - the resident's living space and the government's offices. Furthermore, a discussion is made on how to integrate sensor data from the resident's living space with traditional administrative database, which is a new challenge in the course of synchronizing the two spaces. The implications on the process extension are also provided centering around the shift from reactive to proactive services.

  • This study investigated the microbial community and quality characteristics of traditional soybean pastes (doenjang) based on the aging period in Gyeongnam province. The samples were collected from seven regions in Gyeongnam Province (Goseong, Hadong, Haman, Hamyang, Sacheon, Sancheong and Uiryeong). Contents of moisture, salinity, pH, and acidity of doenjang after 210 days aging were 56.40~65.21%, 9.05~16.08%, 4.88~6.86 and 0.64~2.14%, respectively. Lightness significantly decreased over the aging period, while the redness tended to increase over the aging period. Yellowness was from 21.39~26.81 to 21.10~28.36. Reducing sugar content was from 0.31~1.45% to 0.11~3.13%. The amino-type content increased from 141.87~495.13 mg/100 g to 328.53~823.67 mg/100 g. In contrast, the ammonia-type content declined from 136.74~364.70 mg/ 100 g to 128.62~331.00 mg/100 g. The overall total microbial count did not significantly differ, but it tended to decrease in sample GD4. Fungus declined overall or was not detected. Coliform groups were not detected in all samples. Lactobacillus and Bacillus cereus tended to decrease over the aging period. The common fungus and bacterium were Aspergillus oryzae and Tetragenococcus halophilus, respectively. After the aging period, the predominant fungi were Candida versatilis, Candida apicola, and Debaryomyces hansenii. The predominant bacteria were Tetragenococcus halophilus and Cronobacter sakazakii.

  • 산채류 종자는 주로 농가의 자가 채종으로 생산되고 있다. 농가에서는 종자만을 생산하기 위해서 산채를 재배하지 않으며, 대체로 산채를 수확한 후 채종하는 실정이다. 하지만 종자생산을 위해서 생채나 나물을 언제까지 수확해야 하는지에 대한 한계기 설정이 불분명하다. 따라서 전북농업기술원 허브산채시험장에서는 개미취와 섬쑥부쟁이는 5년생, 곤달비는 3년생 묘목을 이용하여 종자생산을 위한 적정 생채수확 한계기를 설정하고자 시험을 실시하였다. 55% 차광막을 설치한 노지 재배포장에서 생채 수확 한계기를 각각 2020년 4월, 5월, 6월까지로 두어 한계기별 생채 수량, 상품 수량 및 상품율과 개화 시기, 개화율 및 결실률 등을 조사하였다. 개미취의 생채 상품율은 수확 한계기가 늦어질수록 다소 떨어지는 경향이었으며, 개화 시기는 무처리와 4월까지 수확은 동일하였으나, 5월, 6월까지는 수확 한계기가 늦어질수록 지연되었다. 개화율은 대부분 10% 미만이었으며, 5월과 6월까지 생채를 수확한 경우는 추대 및 개화가 거의 되지 않았다. 섬쑥부쟁이는 생채를 6월까지 수확하면 4월까지 수확한 경우보다 약 2배 이상의 생채를 얻을 수 있으나 상품율은 확연히 떨어졌다. 개화 시작은 무처리와 4월까지 수확이 타 처리에 비해 빨랐으나 개화종은 시기에 상관없이 비슷하였다. 또 4월까지 생채를 수확한 경우 무처리보다 개화율, 결실률이 더 높았다. 5월 이후 수확은 생육 부진으로 이어져 개화 및 결실률이 매우 떨어졌다. 곤달비는 개미취와 섬쑥부쟁이에 비해 생채 수확 한계기가 늦어질수록 상품 수량이 눈에 띄게 증가하였으며, 처리 간 추대 시기도 차이는 없었다. 개화율은 5월 수확 이후 낮아졌으며, 결실률은 6월 이후에 급격히 떨어졌다. 따라서 채종을 위해서는 차광재배 시 개미취와 섬쑥부쟁이는 생채 수확시기를 4월 하순, 곤달비는 5월 하순까지로 한정해야 할 것으로 판단된다.

  • 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.

  • The purpose of this study is to investigate the Chinese investment environment and analyze the actual investment condition of Korean enterprises in China and examine the points at issue. In general, the investment environment in China shows satisfactory progress. China has a multiple and regional extension policy in investment. And the environment for investment changes to insufficiency of company profit, extension of service market, maintenance of legislative system, and insufficiency of preference about foreign company. There are situations of inclining to manufacturing, inclining of region, preference of independence investment, small-sized investment by small and medium enterprises, difficulty of financial assistance, excess of logistic cost, delay of logistic term, difficulty of settlement of legal dispute and difficulty of taking a relative information in investment of Korean enterprise in China. The results of the study indicate mostly that the investment of Korean enterprise into China needs turnover of service trade-tertiary industry, portfolio of investment territory, cooperation with Chinese enterprise through joint venture investment and a large-scale investment for extension of Chinese domestic market.

  • This study examines the socioeconomic returns to agricultural research and extension services in Korea, using multivariate time series technique and Akino-Hyami formula. Results find that the socioeconomic returns are quite competitive in case of agricultural research with 44.82% internal rate of return and very high in case of extension services with 207.82% internal rate of return. Agricultural production responds to the agricultural research shock about four years after the shock. The magnitudes of the impacts increase until a peak is reached nine years after the initial expenditures and the impacts declines to a zero level after about twenty years. This lag lengths are consistent to the usual literature on research, which finds lags of seven to thirty years. Agricultural production responds to an agricultural extension shock immediately and declines to a zero level after about four years. Thus, the lag lengths are much shorter than those by research shock.
