This study was undertaken to improve the perceived value of halophytes and contribute to the activity of the local economy by analyzing the antioxidant activity and mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina that grow wild on the mud flats and coastal areas. The total phenolic compound content found in each order is as follows: Suaeda japonica (3.674∼5.989 mg TAE/g dry wt.), Tetragonia tetragonoides (2.515∼4.471 mg TAE/g dry wt.), and Spergularia marina (2.450∼4.067 mg TAE/g dry wt.); DPPH radical scavenging and ABTS cation radical scavenging activities were also recorded in the same order. In the case of minerals, Iron(Fe) was relatively high in Suaeda japonica (960.1∼1,346.7 mg/kg), Manganese(Mn) in Tetragonia tetragonoides (197.1∼574.8 mg/kg), and Zinc(Zn) was relatively high in Spergularia marina (63.19∼216.56 mg/kg). It was confirmed that the mineral content of Suaeda japonica, Tetragonia tetragonoides, and Spergularia marina was significantly higher than that of Chinese cabbage, lettuce, leek, and spinach.

Influence of Al2O3 Content and Cooling Rate on Crystallization in Fe2O3–CaO–SiO2–Al2O3 Systems

Tae Jun Park,Joon Sung Choi,Dong Joon Min 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.9

The behavior of silico-ferrite of calcium and aluminum (SFCA) phases and the influence of sintered ore quality were investigatedusing a confocal laser scanning microscope to understand how the Al2O3content of iron ore affects the sintered orestructure and the crystallization behavior of SFCA in a Fe2O3–CaO–Al2O3–SiO2 pseudo-quaternary system. The experimentalresults were used to inform simulations of the heterogeneous dynamic behavior in response to the rapid temperature changesand various chemical compositions typically encountered in actual sintering processes. Increasing the Al2O3content in theFe2O3–CaO–Al2O3–SiO2 pseudo-quaternary system led to the hematite content decreasing, which affects the reducibilityof the sintered ore. The correlation between the creation of SFCA and the cooling effect associated with varying the Al2O3is discussed in detail.

Nematicidal and egg‐hatching inhibition activities of Kaempferia galanga rhizome‐derived materials and constituents toward root‐knot nematode (Meloidogyne incognita)

Tae‐Kyun Hong,Kym‐Na‐Ra Hwang,Jun‐Ran Kim,Young‐Joon Ahn 한국응용곤충학회 2009 한국응용곤충학회 학술대회논문집 Vol.2009 No.10

The toxicity of Kaempferia galanga rhizome materials and constituents against Meloidogyne incognita second‐stage juveniles (J2) and eggs were examined. The active principles of K. galanga rhizome were identified as the phenylpropanoids ethyl (E)‐cinnamate (EC, 1) and ethyl (E)‐p‐methoxycinnamate (EMC, 2) by spectroscopic analysis. Results were compared with those of carbofuran, fosthiazate, and metam‐sodium. In direct‐contact mortality bioassay, EC (LC50, 0.037 mg/ml) was the most toxic constituent, followed by EMC (0.041 mg/ml). EC was more effective than carbofuran (LC50, 0.092 mg/ml) but less active than fosthiazate (0.002 mg/ml). EC, egg hatch was inhibited 100, 93, and 87% at 125, 62.5, and 31.25 μg/ml, respectively. EMC caused 100, 81, and 75% inhibition of egg hatch at 125, 62.5, and 31.25 μg/ml, respectively. The inhibition of two phenylpropanoids were similar or more inhibition to that of either carbofuran or metam‐sodium but was lower than that of fosthiazate. In contact + fumigant mortality bioassay, EC and EMC treatments resulted in 86 and c 73% mortality at 0.5 and 0.125 mg/g soil, respectively. The lethality of these phenylpropanoids was almost similar to that of either carbofuran or metam‐sodium but was lower than that of fosthiazate. In vapor‐phase mortality bioassay, EC and EMC were more effective in closed container than open containers, indicating that the mode of delivery of these compounds was, in part, a result of vapor action. K. galanga rhizome‐derived materials, merit further study as potential nematicides and hatching inhibitors for the control of M. incognita populations.

목적: in vivo 및 vitro에서 해마 신경세포의 발생단계별 NMDA 수용체 아단위 mRNA 발현에 대한 연 폭로 영향을 알아보고자 하였다. 방법: 흰쥐 해마 신경세포의 발생단계별 NMDA 수용체 NR2A, NR2B 아단위 mRNA 발현에 대한 연의 영향은 정상군과 연 폭로군의 출생 후 7일, 14일, 22일 흰쥐의 해마에서 in situ hybridization으로 mRNA 발현 정도를 densitometer로 측정하여 비교하였고, 연과 NMDA 의 세포독성은 해마 신경세포 일차배양 후 도립현미경을 이용한 형태학적인 관찰과 LDH 활성도를 이용하여 측정하였다. 결과: 연 과 NMDA 에 의한 세포독성에 대한 in vitro 실험에서 형태학적 소견과 LDH 활성도에서 해마 미성숙 신경세포와 성숙 신경세포사이의 차이가 있었으므로, 연과 NMDA 독성효과는 해마 신경세포의 발달 단계에 따라 차이가 있다. 정상군의 해마에서의 NR2A mRNA 발현은 출생 후 연령이 증가함에 따라 점진적으로 증가하였으나, NR2B mRNA 발현은 출생 후 연령이 증가함에 따라 점진적으로 증가하였으나 NR2B mRNA 발현은 연령의 증가에 따른 변화가 없었다. 연 폭로에 희한 NR2A mRNA 발현은 유의하게 감소하였으나(p<0.05), NR2B mRNA 발현은 변화가 나타나지 않았다. 만성적 연 폭로는 NR2A를 포함하는 NMDA 수용체를 감소시킬 수 있음을 알 수 있다. 결론: 연은 해마신경세포의 발생단계에서 NMDA 수용체 아단위 특히 NR2A mRNA 발현의 변화를 야기하여 시냅스 신호 전달에 영향을 나타냄을 알 수 있었다.

우리나라 산림행정 업무의 대부분은 서류 및 대장에 의존하고 있는 실정으로 신속, 정확하고 다양한 업무 처리를 위해서는 첨단의 공잔정보기술을 이용한 과학적인 산림정보 관리시스템의 개발이 시급하다. 특히 지리정보시스템(GIS)과 항공사진 활용기술의 도입은 산림이용기본계획이나 산지개발, 산림자원 관리 및 산림보호 정책 등의 의사결정지원에 효율적으로 기여할 수 있을 것이다. 본 연구에서는 GIS와 항공사진(1998년도 촬영)을 기반으로 주요 산림정보인 수치지도, 수치임상도, 임야도 및 관련 속성데이터 둥을 가공하여 DBMS(data base management system) 내에 저장하였으며, 이를 기반으로 세부 응용시스템인 지번별 임야정보 검색, 산지이용개발 정보관리, 법정제한림 정보관리, 산림자원 정보검색 등의 인터페이스를 개발함으로써 산림 관련 실무자가 산림정보의 종합적인 공간분석 및 질의 검색이 가능한 산림정보 관리시스템을 구축하였다. 본 시스템의 구축으로 산림의 효율적 관리는 물론, 경제적인 산림자원 및 임산업 육성과 쾌적한 산림환경을 조성할 수 있을 뿐만 아니라 관련 부서들 간의 표준화된 공간 자료 공유와 과학적인 정보체계의 연동으로 산림자원 관리를 위한 집약된 공간 및 전자 정보화 인프라 구축의 기반을 마련할 것으로 사료된다. Recently in order to more effectively and scientifically process forest official tasks, which have been focused on documents and inventories, they should be applied with the up-to-date spatial information technologies. Especially, the forest resource information management based on GIS (geographic information system) and aerial orthophoto is expected not only to play an important role as DSS (decision support system) for domestic forest conservation policy and forestry development industry but also to service forest resource information toward people such as the owners of a mountain rapidly. In this study, the important forest information such as digital topography map, digital forest type map, digital forest cadastral map, digital aerial photographs and attribute data were first reprocessed and constructed in DBMS (data base management system). In addition, forest officials could analyze and retrieve forest information by using detail sub-application systems such as forest cadastral retrieval, forest land development information management, reserved forest information management and forest resource information retrieval. For this, the user interface is developed by using Visual Basic 6.0 and MapObjects 2. 1 of ESRI based on CBD (component based development) technology. The result of developing this system will not only perform constructing economical forest and better environment but also be the foundation of domestic spatial technology for forest resource management.
