In order to produce hemp with low cannabinoids and appropriate fiber yield, seeds of the IH3 (non drug type germplasm) and local variety (drug type cultivar) were mixed to 1:1, 2:1, 3:1 on base of seed weight ratio and cultivated for seed production. In the seed yield trial, the weight of 1000 grains were around 21 g, which was increased in proportion to the ratio of IH3 seeds but seed yield were 100 kg/10a, which were not significantly different by the seeds-mixing ratio. In fiber yield trials with seeds from seed yield trial, fiber yield ranged $193{\sim}198kg/10a$ which was not significantly different by the seeds mixing ratio but the content of THC(${\Delta}$-9-tetrahydrocannabinol) was lowered in proportion to the ratio of IH3 seeds. Variation of THC and CBD (Cannabidiol) level in the 150 plant cultivated with various seed mixing ratio reflected that the percentage of drug and intermediate type were decreased but non drug type were increased in proportion to the ratio of IH3 seeds.

This study has purpose in analyzing the characteristics of small weddings reported in the internet news, and suggesting the plan to activate it. The materials are about 248 internet news from 2012 to 2018, and frequency analysis and chi-square test were conducted for it. The research result is like the following. 1. It was reported that the saving type was higher in 2016 and the money gift improving type was higher rate in 2015. 2. As a venue for wedding, it was reported the saving type and free type choose the public institution, the small size type hotels, the peculiar type outdoor and house, money gift improving type hotel and public institutions. 3. The saving type, peculiar type and free type were likely to be reported as information transfer, and the small size type and the money gift improving type were likely to be reported to suggest the case of small weddings. 4. Case type showed high rate for public institutions and hotels for small weddings, and information type showed high rate for public institution for small wedding venue. 5. Case type and information type showed favorable rate for small wedding, and opinion type appeared similar favorable rate and unfavorable rate for small weddings. 6. Ordinary people showed high rate to be reported with saving type, celebrities were with small size type. And also the ordinary people showed high rate public institutions, celebrities with hotel as small wedding venue. 7. The items to save the cost in small wedding included more of venue renting cost, reception cost, wreath/decoration cost, photo filming cost than marriage expenses and wedding gifts, house.

A crude crystal of phytoecdysone was obtained 355 mg per Kg dry radix of A. japonica, and it was identified to $\beta$-ecdysone by TLC. Feeding silkworms on mulberry leaves sprayed with the extract, mounting time shortened and pupation ratio improved. The feeding effects of the extract was differed according to the rearing seasons, spring and summer. In spring season, only mounting time shortened without any difference in pupation ratio from the control. In summer season, not only mounting time shortened, but also pupation ratio remarkably advanced.

To isolate naturally occurring novel Bacillus thuringiensis strains for useful pest con시 agents, A total of 64 isolates of B. thuringiensis producing spore and crystal were obtained from 583 soil samples in Korea. Toxicity of isolates was assayed against Lepidoptera (Bombyx ori), Diptera (Culex pipens) and Coleoptera (Sitophilus oryzae), respectively. The results showed that B. thuringiensis isolates toxic Lepidoptera are 42.2% , both Lepidoptera and Diptera are 31.3% and Diptera are 20.3%, demonstrating that spectrum of insecticidal activity of B. thuringiensis isolates is various. But no B. thuringiensis isolates have toxicity against Coleoptera.

농업 비점오염원으로부터의 수질 보전이나 수자원 관리는 유역단위로 하여 농업적 관리뿐만 아니라 수질 관리 및 수자원 관리를 위해서도 유역단위 특히, 소유역의 토양특성을 포괄하는 단위로 체계적으로 분류할 필요성이 있다. 우리나라의 남서쪽에 위치한 영산강유역의 50개 소유역을 대상으로 토양도, 지형도, 하천도 및 유역도를 이용하여 만곡도, 산림의 비율, 평탄지의 비율, 다른 소유역으로부터의 유입이 있는지의 여부 등 토양학적으로 중요한 4개의 특성을 가지고 군집분석을 수행하였다. 그 결과 5개의 군으로 구분할 수 있었으며, 이 구분의 적합도를 검정하기 위하여 Mantel test를 한 결과 r = 0.81825로 나타나 적합하다는 결론을 얻었다. 이와 같이 토양과 지형특성을 포괄하는 소유역의 분류 및 유사성에 따른 그룹화는 농업에서의 최적영농관리나 오염물질에 따른 수질관리, 수문모형의 적용성 확대 및 수자원 관리에 합리적 유용성을 제공할 것이며 체계적 관리의 밑바탕이 될 것이다.

We study how the three antecedents of trust such as integrity, ability and benevolence affect trust building, based on the articles extracted from the New York Times during 1981-2010. Major findings are that the ratio of negative impact on trust from integrity is 86%, whereas the ratios of positive impact on trust from ability and benevolence are 70% and 71% respectively. Statistical tests show that the hypothesis that the negative impact of integrity on trust build-up will be higher is supported, but the most unstructured benevolence related hypotheses are not confirmed due to small sample sizes. Based on the study, we suggest that the future direction of IT application should accommodate benevolence factor seriously to fulfill corporate social responsibility.

지하수 인공함양은 수자원확보 및 비상시 용수를 목적으로 세계적으로 연구 및 프로젝트가 진행되고 있다. 인공함양의 방법에는 여러 가지의 방식이 있지만 본 연구는 관정을 통해 주입하는 ASTR(Aquifer Storage Transfer and Recovery)방법을 이용하여 연구하였다. ASTR이란 지표수를 인공적인 방법으로 대수층에 주입시키고, 일정기간 저장시키거나 유하시킨 후 양수하는 방법이다. 염수로 포화된 피압대수층에 담수를 주입하여 염수를 치환할 수 있는 주입-양수 시스템을 연구하였다. 염수로 포화된 대수층에서 인공함양기술을 성공시키기 위해서는 양수정으로 유입되는 염수비율이 0%을 만족하며, 주입으로 인한 수위상승량은 지반변형을 일으키지 않는 최소한의 값을 가지는 것이다. 본 연구는 앞서 언급한 인공함양기술을 성공시키기 위해 지하수 흐름모델과 최적화 모델을 결합한 최적전산모델을 이용하여 모의하였다. 지하수 흐름모델은 경계면모델을, 최적화 기법은 GA(Genetic Algorithm)을 이용하였다. 구축된 목적함수로는 양수정의 담수비율 최대화, 주입정에서의 수위상승량 최소화 그리고 양수개시시간 최소화로 구성하였다. 제약조건으로는 총 주입량 및 양수량 그리고 주입 및 양수정 개수이다. 서술한 목적함수와 제약조건을 만족하는 주입/양수정의 위치 및 유량을 최적전산모델로부터 얻을 수 있다. 기존 지하수 인공함양 및 개발은 사례별 연구 또는 전문가의 주관적 판단에 의존하는 경향이 있었다. 본 연구는 최적화 기법을 통해 복수의 관정에서 정량적인 산정이 가능하다. 현재 모델링에 의존한 연구로써 한계가 있지만, 추후 실제현장에 적용하여 모델 검정을 통해 신뢰도를 높이며 지하수 인공함양 개발에 많은 공헌을 할 수 있을 것으로 예상한다.

This study investigated whether culture filtrates produced by Xylella fastidiosa can be used to determine the varietal susceptibility to Pierce's disease in grapevines (Vitis spp.) as a substitute for pathogen inoculation or field screening. A bioassay of grape leaves with culture filtrates from the pathogen showed that their phytotoxicities were active and host-selective. Ethyl acetate extracts from them also showed toxicities and host selectivity in both bunches of grapes and muscadine grapes. The sensitive range of plants to the culture filtrates and their ethyl acetate extracts was consistent with the host range of the Pierce's disease pathogen. Susceptible cultivars are sensitive to even highly diluted culture filtrates, while resistant cultivars were not affected even at their original culture filtrates. Susceptible cultivars were more sensitive to the undiluted culture filtrate than were highly diluted culture filtrates, and the younger leaves were the most sensitive to the culture filtrates in grapes. Although some European grape cultivars showed moderately susceptibility in this study, the determination of varietal resistance to Pierce's disease by the treatment of culture filtrates of pathogens could provide valuable information for the preliminary selection of genetic resources and seedlings from hybridization in a disease resistant grape breeding program.

To Confirm the repression of off-odor and improvement of food quality in small black bean chungkugjang (SBC), some taste compounds of SBC added with kiwi and radish homogenate and fermented fro 3 days at 42$^{\circ}C$ were investigated. Contents of free amino acids in SBC were lower than that of soybean chungkugjang (SC) and were increased by adding kiwi and radish homogenate to black bean, indicating that two materials were effective to the enzymatic digestibility of soy protein. Of organic acids, citric acid was the most abundant, followed by acetic acid and lactic acid. Fatty acid composition was high in the order of linoleic acid (50.82~54.51%), oleic acid (17.76%~22.10%) and plamitic acid(12.13~13.79%). There were no significant difference in compositions of organic acids and fatty acids of chungkugjang. Major volatile compounds of SBC were indole , 2-5-dimethyl pyrazine and trimethyl pyrazine. Contents of alkyl pyrazines that contribute the characteristic aroma and flavor of SBC added and fermented with kiwi and radish homogenate were 3 times lower than those of SC. Uracil and UMP were major nucleic acie-drlated compounds in all four chungkugjangs. Contents of the other nucleic acid-related compounds were a similar trend in all chungkugjangs.
