  • 사일리지용 옥수수 만파재배시 잡초방제를 위해서 알라유제 + 씨마네수화제외 4종의 제초제를 공시하여 6처리 난괴법 3반복으로 시험을 수행한 결과 얻어진 성적을 요약하면 다음과 같다. 1. 제초제 처리후 옥수수 출현은 처리간 차이 없이 양호하여 공시한 제초제 모두 옥수수에 약해를 미치지 않았다. 2. 제초제 처리별 잡초방제는 기존처리구인 알라유제 + 씨마네수화제 처리구보다는 파라코액제, 글라신액제, 글루포시네이트암모늄액제 및 설포세이트액제를 추가한 처리구에서 방제율 92-94%로 우수하였다.(중략)

  • A high-efficiency turbo steam compressor has been successfully developed for the MVR desalination system, first one in Korea. The state-of-the-art design methods using real gas properties were applied to get all the aerodynamic design results. Bull and pinion gear trains, tilting-pad bearings and investment cast impellers were developed also to be integrated into the integral gear-driven turbo steam compressor. System tests show highly efficient performance.

  • 기계적 증기재압축(Mechanical Vapor Recompression) 시스템은 증기를 압축하여 압력을 올리면 온도가 상승하는 원리를 이용한 것으로서 시스템의 최종 증발관에서 발생한 저온의 증발증기를 전량 증기압축기로 압축ㆍ승온하여 자신의 최초 증발관의 가열 열원으로 재사용 하는 방식이다. 따라서 이 사이클에 필요한 보충열원은 가열측과 증발측과의 온도상승분 만큼만 증기의 포화온도를 올리면 되므로 에너지절약 효과가 매우 크다.(중략)

  • Contamination of public bath water by waterborne pathogens can cause disease outbreaks and contribute to background rates of disease. The aim of this study is to determine the prevalence of waterborne pathogens in public baths. A total of 30 water samples were collected from 30 different public baths in seoul, Korea. Pathogens in water samples were concentrated by 0.45 ${\mu}m$ nitrocellulose membrane filter, analyzed by both cultivation and polymerase chain reaction-reverse blot hybridization (PCR-REBA) of partial 16S rRNA gene. Various microorganisms including Escherichia coli and Shigella spp. were identified by microbiological cultivation. E. coli, Shigella spp., Salmonella spp., Pseudomonas spp. and Mycobacterium spp. were identified by PCR-REBA. Our results suggest that appropriate hygiene practice and continuous monitoring is needed for reducing health risk associated with public bath houses.

  • Antifungal substances were isolated and identified from garlic and taxus extracts to develop safe and broad fungicide. The inhibitory effect of seedborn disease of sesame, pepper, radish, chinese cabbage by formulation of antifungal substances was investigated. The antifungal substance isolated through column chromatography from garlic and taxus extracts was confirmed by GC-MS as allicin($C_6H_{10}OS_2$) and taxol($C_{47}H_{51}NO_{14}$) and the quantified content from each extracts by HPLC analysis was 0.62%, 0.29%, respectively. The formulation composed of garlic and taxus extracts controlled effectively the seedborn fungi tested in this study at 10X dilution, but at 100X dilution the inhibitory effect decreased. Phytotoxicity of these formulations did not recognized.

  • The main purposes of this study are to explore the factors related to the elderly's sexual life continuance and satisfaction in Daegu area. The data were collected from May 1st, 2017 to July 31st in 2018 by face-to-face interviews. 259 cases were used for the final statistical analysis, such as logistic regression analysis and multiple regression analysis. 29% of the respondents continued their sexual life and approximately 55% of them were satisfaction in their sexual life. According to the logistic regression analysis, independent variables such as, age, having wife, and living with wife only have statistically significant relationships with the male elderly's sexual continuance. Frequency of sexual intercourse, number of disease, and the experience of venereal disease have statistically significant relationships with the elderly's sexual life satisfaction.
