콩의 증자조건에 따른 검정콩 전통간장의 숙성 후 유리당, 유기산, 지방산조성을 조사하였다. pH 값은 5.04~5.32로 시험구간의 큰 차이를 나타내지 않았고, 원료 콩을 상압증자한 검정콩 간장이 가압이나 스팀보다는 약간 높은 수치를 나타내었다. 적정산도는 4.26~7.73mL로 나타났으며, 가압증자한 검정콩 간장(4.26~5.61mL)이 가장 높았으며, 다음으로 상압(7.32mL), 스팀(5.99~6.96mL)의 순으로 나타났다. 환원당은 25.18~194.81㎎%로 나타났고, 상압이 25.18㎎%로 가장 낮았으며, 가압이나 스팀증자한 검정콩 간장의 경우 상호간에는 큰 차이가 없지만, 상압한 것보다는 7~8배 높은 함량을 나타내었다. 주요 유리당은 glucose, fructose, xylose였으며, 스팀증자한 검정콩 간장이 상압이나 가압보다 각각의 유리당 모두가 많았고, 상압증자는 유리당이 극히 미량으로 검출되었다. 주요 유기산은 succinic acid, oxalicaicd, tartaric aic, malic acid, citric acid였고, 총 유기산은 스팀증자 (40.38~76.96 ㎎%)한 검정콩 간장이 상압(55.85㎎%)이나 가압(27.78~34.21)한 것보다 많았다. 증자 처리시간이 길수로 가압과 스팀으로 처리하여 제도된 검정콩 간장은 약간씩 감소되는 경향을 나타내었다. 주요 지방산은 palmitic acid(33.28~43.51%), stearic a창(14.15~19.16%), myristic acid(5.03~19.14%)였으며, 전체 지방산 중에 55.97~72.85% 비율을 차지하였고, 원료 콩에 존재하지 myristic acid가 상당히 많이 존재하였다. pH values in all samples were in the range of 5.04 to 5.32. pH of kanjang prepared with normal pressure(HPK) was higher than that of kanjang prepared with high pressure(HPK) and kanjang prepared with steam(SPK). Titratable acidity(TA) in all samples were found to be 4.26∼7.72 mL. TA in HPK(5.99∼6.96 mL) was lower than that in SPK(4.26∼5.61 mL) and NPK(7.32 mL). Reducing sugar(RS) contents in all samples were in the range of 25.48 to 194.81 ㎎%. Rs contents of HPK and SPK were a similar pattern and were higher than that of NPK. Major free sugars(FS) were glucose, fructose and xylose. In total FS, SPK was higher than that of NPK and HPK. Major organic acids(OA) were succinic acid, oxalic acid, tartaric acid, malic acid citric acid. OA contents in HPK and SPK were decreased slightly according to the heating time of whole black bean. The highest percentage of fatty acid(FA) in all samples was palmitic acid(33.28∼43.51% as area % of GC chromatogram), followed in a decreasing order by stearic acid(14.15∼19.16%) and myristic acid(5.93∼19.14%). The composition ratios of three FA to total FA ranged from 55.97 to 72.85%. In all samples, there was myristic acid that was not contained in raw soybean.

Mi-Jung Bae,Hyunduk Cho,Tae-Sung Kwon,Jung Hwa Chun,Young-Seuk Park 한국응용곤충학회 2015 한국응용곤충학회 학술대회논문집 Vol.2015 No.04

Benthic macroinvertebrates are sedentary and have an intermediate life span ranging from months to a few years. They play a key role as consumers in the food trophic structure by linking producers, top carnivores, and decomposers in aquatic communities. Therefore, they have been widely used for ecological assessment of aquatic ecosystem health in an integrative and continuous manner. In this study, we characterized benthic macroinvertebrate communities at reference sites, which are not disturbed. Benthic macroinvertebrates were collected seasonally with a Surber net at three different streams (Pocheon, Hongcheon, and Namhae). In addition, hydrological and physicochemical environmental factors including temperature, discharge, width, conductivity, dissolved oxygen and pH were also measured at each sampling site. Spatial and temporal differences of benthic macrointertebrate communities were analyzed based on community indices, functional guilds, etc. relating to their environmental factors. Multivariate analysis were used to characterize the relationships between communities and environmental factors. Benthic macroinvertebrates were significantly different among sampling sites reflecting differences of their environmental condition such as hydromorphological factors, meteorological factors, etc.

Mi-Jung Bae,Jung Hwa Chun,Tae-Sung Kwon,Young-Seuk Park 한국응용곤충학회 2015 한국응용곤충학회 학술대회논문집 Vol.2015 No.10

Headwater streams are the main sources of water sediment and organic material for downstream reaches and their small catchments coupled terrestrial-aquatic linkages. Because headwater streams provide valuable habitats for unique and diverse assemblages of aquatic fauna, they are also essential for sustaining the structure and function of the watersheds. Therefore, it has been recently supported that headwaters are important areas for maintaining biodiversity. In this study, we surveyed four different headwater streams in different watersheds to characterize differences of benthic macroinvertebrate assemblages among study streams. Benthic macroinvertebrates were collected seasonally with a Surber net at four different streams. In addition, hydrological and physicochemical environmental factors including temperature, discharge, width, conductivity, dissolved oxygen and pH were also measured at each sampling site. Community indices were used to differentiate spatiotemporal changes of macrointertebrate communities. Multivariate analysis were used to characterize the relationships between communities and environmental factors. Differences of their environmental condition such as meteorological factors and stream hydromorphological factors were reflected in the ordination with macroinvertebrate communities.

Larvicidal activity of medicinal plant extracts and lignan identified in Phryma leptostachya var. asiatica roots against house fly (Musca domestica L.)

Il-Kwon Park,Seon-Mi Seo,Yoon-Mi Jeon,Sung-Woong Kim,Hwa-Jeong Yeom,Hyo-Rim Lee 한국응용곤충학회 2013 한국응용곤충학회 학술대회논문집 Vol.2013 No.10

Medicinal plant extracts from 27 plant species in 20 families were tested for their larvicidal activity against house fly, Musca domestica (L.). Responses varied with plant material and concentration. Among plant species tested, Phryma leptostachya var. asiatica showed 100% larvicidal activity against M. domestica at 10 mg/g concentration. Larvicidal activities of Atractylodes japonica, Saussurea lappa, Asiasarum sieboldi, and Gleditsia japonica var. koraiensis were 89.3, 85.3, 93.3 and 96.6% at 10 mg/g concentration, respectively. Extracts of Prunus persica, Curcuma longa and Paeonia moutan produced moderate activity. Larvicidal activity of other plant extracts was less than 50%. Among test plant species, Phryma leptostachya var. asiatica showed the most potent larvicidal activity. The active constituent of P. leptostachya var. asiatica roots was identified as the leptostachyol acetate by spectroscopic analysis. The LC50valuesofleptostachyolacetateagainstM. domestica larvae was 0.039 mg/g. Naturally occurring medicinal plant extracts and Phryma leptostachya var. asiatica root–derived compounds merit further study as potential house fly larval control agents or lead compounds.

Il-Kwon Park,Sung-Woong Kim,Hwa-Jung Yeom,Yoon-Mi Jeon,Seon-Mi Seo,Sang-Chul Shin 한국응용곤충학회 2012 한국응용곤충학회 학술대회논문집 Vol.2012 No.10

The box tree pyralid, Glyphodes perspectalis, was reared on an artificial diet based on dried powder of box tree leaves, Buxus microphylla var. koreana, and INSECTA F-II (Nihon Nosan Co., Ltd) at a ratio of 3:7 (w:w) and analyzed in their developmental characteristics from 1st to 4th generation. The developmental period of larva reared on artificial diet was longer than that of larva reared on host plant. Significant difference in larval period was also observed between 1st and other generation groups. Pupation rate was the highest in 4th generation followed by 3rd, 2nd, 1st and host plant group. Significant difference in pupal period was noted between 1st and 3rd generation group. Emergence rate was the highest in 4th generation group followed by 3rd, host plant, 1st and 2nd generation group. There is a significant difference in male and female size between 1st and 4th generation group. Our result indicated that stable rearing of box tree pyralid through the year is possible by artificial diet, and the best adaptation to artificial diet was achieved at 4th generation.

To investigate the alleviative effects of Peonia japonica water extract (PJWE) on inflammation and skin barrier damage, both the irradiation of UVB and the application of squalene monohydroperoxide (Sq-OOH) to the backs of hairless mice were performed for 4 weeks. And at the same time experimental materials were applied topically. The skin erythema indices for the positive control (PC, 0.01% retinoic acid) and experimental (E, PJWE) groups were lower than that of the control (C) group. Whereas both the lipid and water capacities for the PC and E groups were higher than those of the C group. Epidermis and dermis of the C group were remarkably thickened in comparison with the PC and E groups. Relatively much less number of inflammatory cells, including lymphocytes, neutrophils and macrophages were found in dermis of the PC and E groups compared with the C group. Lipid lamellae of the C group were broken severely showing an irregular arrangement and lipid content was much reduced. Whereas those of the PC and E groups were almost intact with a regular arrangement, which were similar to that of the N group. Taken the results all together, it was confirmed that PJWE could be effective natural herbal material for the alleviation of inflammation and skin barrier damage in hairless mice skin which were induced by UVB and Sq-OOH.
