1) 본 시험은 malathion이 방충제로 사용되었을 때 자연적인 곡물저장조건하에서의 잔류효력과 그의 지속성을 검정하기 위해서 1963년 6월부터 9월에 걸쳐 행하였다. 2) 백미를 malathion 유제로 처이하고 일령 21일된 쌀바구미를 일정기간마다 8일간 접종하여 살충율을 을 조사하고 이로서 malathion의 잔류효력과 지속성을 판정하였다. 3) 처리후 8일까지는 각 실험농도에서 의 살충율을 나타내었고 32일에서 8ppm과 16ppm은 의 살충율을 보였으나 4ppm과 2ppm에서는 각각 와의 살충율을 보였다. 32일 이후에서는 어느 농도에서나 의 살충율은 볼 수 없었고 107일에 이르러서는 각 농도간 살충율에 차가 없었다. 4) 처리한 malathion의 반감기는 즉의 살충율을 나타낸 것은 2ppm에서 33일, 4ppm에서 54일, 8ppm에서 73일. 16ppm에서 93일 이었다. 5) 자연곡물저장조건하에서 malathion 잔류효력을 5개월간 보지하려면 본 실험에서 사용한 농도보다 훨씬. 높여야 될 것으로 생각된다.

The purpose of this study was to analyze the status of conservation and management of KIAHS(Korea’s Important Agricultural Heritage System) by focusing on which of the conceptual and institutional characteristics and stakeholder activities, and to suggest improvement plans. The results were summarized as follows, first, insiders prioritize financial support and participate in plan execution and activities. Second, rural utilization and traditional agricultural succession activities and support are deficient. Third, administrators (intermediary) focuses primarily on KIAHS designation; ordinance enactment, manpower recruitment and other structural considerations are lacking. Fourth, the role of administrators (intermediary) is limited to operational funding and facility management support at the enforcement and activity stage. Fifth, outsiders besides visitors, such as the public or business enterprises, lacked participation methods. For the sustainable KIAHS, municipality must perceive agricultural heritage as a resource and recognize the importance, and treat it accordingly. The establishment of local-led conservation activities and movements must be considered in an enhanced investigation and excavation stage. The complementary policies that ensure continual support from experts from the first investigation and excavation stage to the final monitoring stage are necessary. The standards and regulations are necessary to achieve parity between conservation and maintenance of agricultural heritage, and its utilization.

한국의 농업유산 정책은 2002년 FAO가 도입한 GIAHS 제도를 바탕으로 2012년에 농림축산식품부가 도입하였다. 현재 한국 국가중요농업유산(KIAHS)지역으로 지정이 되면, 농림축산식품부의 다원적 자원 활용사업에 의해 3년간 보전 관리를 위한 예산지원을 받도록 제도화되어 있다. 그렇지만, 다원적 자원 활용사업 종료 이후 KIAHS 지역에 대한 실질적인 관리체계는 마련되어 있지 않은 상황으로, 이에 대한 연구가 시급한 상황이다. 따라서 본 연구는 KIAHS 지역에 대한 지속적 관찰 및 데이터 구축을 위한 모니터링 지표 개발을 통하여, 지속가능하고 효율적인 KIAHS 지역의 보전관리체계를 마련하는 것을 목적으로 한다. 이를 위해, 본 연구는 문헌고찰, 해외사례 조사, 전문가 그룹 인터뷰를 통한 지표의 검증 및 현장 적용의 연구방법을 통하여 모니터링 지표 및 관리체계를 도출하였다. 모니터링 지표는 단계별 검증절차를 거쳐서 총 17개의 공통지표와 각 지구의 특성을 반영하는 자율지표로 구성하여 제시하였다. 제시한 모니터링 지표들은 준비-지정-관리의 3단계로 구분하여 단계별로 적용가능한 지표를 제시하고, 측정시기와 방법, 측정주체 등 관리체계 구축에 필요한 항목들을 함께 제시하였다. 본 연구는 한국 국가중요농업유산의 보전과 관리를 위한 정책적 시사점을 제시하는 데 의의가 있다.

The large extracellular domain of glycoprotein hormone receptors is a unique feature within the G protein-coupled receptors (GPCRs) family. After interaction with the hormone, the receptor becomes coupled to Gs, which, in turn stimulates adenylyl cyclase and the production of cAMP. Potential phosphorylation sites exist in the C-terminal region of GPCRs. The experiments described herein represent attempts to determine the functions of the eel follicle-stimulating hormone receptor (eelFSHR). We constructed a mutant of eelFSHR, in which the C-terminal cytoplasmic tail was truncated at residue 614 (eelFSHR-t614). The eelFSHR-t614 lacked all potential phosphorylation sites present in the C-terminal region of eelFSHR. In order to obtain the eelFSHR ligand, we produced recombinant follicle-stimulating hormone (rec-eelFSHβ/α) in the CHO-suspension cells. The expression level was 2-3 times higher than that of the transient expression of eelFSH in attached CHO-K1 cells. The molecular weight of the rec-eelFSHβ/α protein was identified to be approximately 34 kDa. The cells expressing eelFSHR-t614 showed an increase in agonist-induced cAMP responsiveness. The maximal cAMP responses of cells expressing eelFSHR-t614 were lower than those of cells expressing eelFSHR-wild type (eelFSHR-WT). The EC50 following C-terminal deletion in CHO-K1 cells was approximately 60.4% of that of eelFSHR-WT. The maximal response in eelFSHR-t614 cells was also drastically lower than that of eelFSHR-WT. We also found similar results in PathHunter Parental cells expressing β-arrestin. Thus, these data provide evidence that the truncation of the C-terminal cytoplasmic tail phosphorylation sites in the eelFSHR greatly decreased cAMP responsiveness and maximal response in both CHO-K1 cells and Path-Hunter Parental cells expressing β-arrestin.

This study has been conducted to understand the relationships such as interspecific interactions between species and landscapes within and outside of agricultural land by identifying the flora features of Cornus officinalis farmlands in Gurye which designated as Korea's Important Agricultural Heritage System. For this, the flora of vascular plants was surveyed in every land uses of two representative districts. These two districts represent the own features of Cornus officinalis farming area which including land uses like forests(especially pine tree), valley, farmland(rice paddy, farms, Cornus officinalis farmland), and residence. Also differences in flora by stone wall’s existence and Cornus officinalis’s DBH were surveyed. As a result, Cornus officinalis farmlands showed the various vascular plants than the other land uses. According to the existence of stone wall in Cornus officinalis farmlands, there were no differences in appearance flora. But the flora in Cornus officinalis farmlands which have different Cornus officinalis’ DBH(Divided into average over 15cm and under 8cm), various plants were showed in average over 15cm than average under 8cm. In conclusion, Cornus officinalis farmlands have been actively engaged in various types of land use and species exchanges, including forests, valleys, villages, and fields, and it has been confirmed that it acts as an ecological axis connecting forests to villages.

The paradigm of agricultural and rural policies has shifted from food production and profitability to the competitiveness of rural areas through the discovery, grants and use of the agricultural and rural resources' potential value. This study aims to discover the value of the agriculture and rural resources and intend to offer the method for discovering resources and its value as the agricultural heritage. To this end, the functions and values of the agricultural and rural resource, the criteria and procedure of Globally and Nationally Important Agricultural Heritage System which is leading institutions were investigated. The policy implications were proposed in the process and series of steps of discovery and evaluation of the pluralistic value of the agriculture and rural resources and agricultural heritage designation and management.

In order to cope with the recent global warming and climate change that is projected to have a grave impact on agriculture worldwide, we will direct our focus on developing crops tolerant to multiple abiotic stresses including drought, cold and heat, with the following research activities conducted by three different research groups including an international research team at IRRI. 1) Development of heat/cold tolerant rice variety : Major genes conferring heat tolerance and cold resistance in rice will be identified by comparative transcriptome analyses and new molecular markers will be developed based upon these data. EMS mutagenesis and proteomics analyses will accompany this approach to supplement this gene identification and marker development efforts. Once reliable markers are obtained in this way, new varieties of heat/cold tolerant japonica rice will be bred through introgression of these genes. 2) Development of drought/heat tolerant rice variety : Through QTL mapping conducted on RILs between a drought resistant line and an elite line, genes conferring drought/heat tolerance will be identified and molecular markers will be developed using SNP/GBS genotyping methods. Using these markers, new rice varietis with drought/heat tolerance will be bred by employing marker assisted selection (MAS) as well as marker assisted backcross (MABC). 3) Identification of genes involved in multiple stress responses in ginseng and brassica : Molecular breeding of stress tolerance traits in ginseng and brassica is not well established to date. Taking advantage of the ginseng whole genome sequence data information and other comparative genomics approaches, members of the stress-response transcription factor family CBF/DREB will be identified and their functional analyses will be performed in ginseng and brassica using transcriptome profiling of both wild type and transgenic plants including the adventitious root-derived transgenic ginseng.

This experiment was carried out to find suitable sample type for the more accurate prediction and non-destructive way in the application of near infrared reflectance spectroscopy (NIRS) technique for estimation the protein, total amino acids, and total isoflavone of soybean by comparing three different sample types, single seed, whole seeds, and milled seeds powder. The coefficient of determination in calibration (R2 ) and coefficient of determination in cross-validation (1-VR) for three components analyzed using NIRS revealed that milled powder sample type yielded the highest, followed by single seed, and the whole seeds as the lowest. The coefficient of determination in calibration for single seed was moderately low(R2 0.70-0.84), while the calibration equation developed with NIRS data scanned with whole seeds showed the lowest accuracy and reliability compared with other sample groups. The scatter plot for NIRS data versus the reference data of whole seeds showed the widest data cloud, in contrary with the milled powder type which showed flatter data cloud. By comparison of NIRS results for total isoflavone, total amino acids, and protein of soybean seeds with three sample types, the powder sample could be estimated for the most accurate prediction. However, based from the results, the use of single bean samples, without grinding the seeds and in consideration with NIRS application for more nondestructive and faster prediction, is proven to be a promising strategy for soybean component estimation using NIRS.

Hibiscus cannabinus, Cassia fistula and Abutilon indicum are medicinally important plants in India. Tissue culture studies have done for efficient propagation and for crop improvement in these three plants. Various explants were tried for callus induction, somatic embryogenesis and organagenesis with manipulation in culture media. Calli and somatic embryos were induced from hypocotyl explants in Hibiscus cannabinus, while in Cassia fistula and Abutilon indicum it could be obtained from leaf explants.

In this study, the distribution characteristics of volatile organic compounds (VOCs) were investigated on the seasonal basis across spring, summer, and fall during the year of 1998. According to this analysis, most VOC species investigated exhibited strong temporal trends. Over diurnal scale, there distribution characteristics were affected by seasonal factors strongly. While they showed high day/night ratio pattern during spring, the pattern was reversed during fall. When the seasonal mean values were compared between the two seasons, the spring values were systematically higher than their counterparts in most cases. In addition when our VOC measurement data were compared with those reported from elsewhere, we were able to conclude that the VOC levels in the study area are comparable to the level weakly impacted by the regional emissions of VOCs. Although our data are not sufficient enough to systematically explain the atmospheric distribution and behavior of VOCs, the findings of strong correlations among some of VOC species suggests strong need for investigating their interactions in the earth's atmosphere.
