The genus Nola (Nolidae, Nolinae) was established by Leach (1815), with the Noctua palliola Denis & Schiffermüller, 1775 (a junior subjective synonym of Phalaena cucullatella Linnaeus, 1758) from Vienna, Austria. Nola comprises over 200 species: Africa and western Palearctic approximately described 100 speices (Hacker et al., 2012); Oriental and Eastern Palearctic regions have over 100 species (László et al., 2010; Sasaki et al., 2011; Kononenko and Pinratana, 2013). Two species of the genus Nola Leach; Nola euryzonata (Hampson, 1900) and Nola lucidalis (Walker, 1865), reported for the first time in Laos. Illustrations of adults and genitalia of all the examined species are provided.

국화과에 속하는 큰비쑥은 ‘갯쑥’으로도 알려져 있는 염생식물로서 생물학적 이용 가능성이 높은 2차 대사산물이 풍부할 것으로 기대되며, 항염, 항산화, 미백효과 등 다양한 생리 활성이 있다고 알려져 있다. 따라서 본 연구에서는 큰비쑥을 경쟁력 있는 작물로써 이용성을 높이고자 생장 환경별 총폴리페놀 함량, 라디칼 소거능, 무기질 함량, 중금속 및 잔류농약을 분석하였다. 총폴리페놀은 가장 높은 함량을 보인 자생 성숙잎을 제외하고는 유의적인 차이가 없었으나(p<0.05), ABTS 및 DPPH 라디칼 소거능은 자생잎보다 재배잎에서 높은 활성을 보였다. 이는 폴리페놀 화합물의 구조적 요인이나 폴리페놀 화합물 이외의 영양성분들이 라디칼 소거능에 복합적으로 작용한 결과로 판단된다. 무기질 중 Na 함량은 자생 어린잎이 가장 높았으나, Na을 제외한 총 무기질 함량은 재배잎이 자생잎보다 높았다. K 및 Ca 함량은 자생잎보다 재배잎이 높았다. 큰비쑥 4종의 안전성을 알아보기 위해 중금속을 분석한 결과, Pb, Cd, As, Hg이 검출되었으나, 엽채류 식약처 고시 기준인 Pb 0.3 mg/kg, Cd 0.2 mg/kg보다 낮은 수준으로 나타났고 전반적으로 재배잎이 자생잎보다 낮게 측정되었다. 잔류농약은 큰비쑥 4종에서 검출되지 않아 안전하다고 판단된다. 결론적으로 본 연구를 통해 재배 큰비쑥은 전라남도 해안지역 자생 큰비쑥과 비교하여 큰 차이가 없어 재배잎을 육종하여 대량생산한다면 이용 가능성이 높은 품종으로 활용 가능하다고 판단된다. Artemisia fukudo Makino belongs to the Asteraceae family, is a halophyte that can grow in salinity soils and is known for its various physiological activities. However, few studies were comparing it according to the growth environment. Therefore, in this study, we analyzed the antioxidant activity, functional ingredients, and safety of Artemisia fukudo Makino according to the growth environment. Total polyphenol content was the highest in native mature leaves, but 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) and 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity was higher in cultivated leaves than in native leaves. The total mineral content, excluding sodium, was higher in cultivated than in native leaves. The content of potassium and calcium was higher in cultivated leaves than in native leaves. In addition, heavy metal analysis showed that cultivated leaves were generally lower than those of native leaves. Residual pesticides were not detected in all samples. In conclusion, since there is no significant difference in cultivated leaves compared to native leaves, it was judged that cultivated leaves could be used as a variety to be grown and mass-produced.

소나무(Pinus densiflora) 목질을 이용한 수용액 중의 Cu(II)흡착

김하나,박세근,양경민,김영관 강원대학교 산업기술연구소 2007 産業技術硏究 Vol.27 No.A

Milled Korean pine (Pinus densiflora) wood was used to evaluate its adsorption capacity of Cu(Ⅱ) ions from aqueous solution by running a series of batch experiments. Prior to the tests, the milled woods were pretreated with 1N NaOH, 1N HNO_(3), and distilled water, respectively, to examine the effect of pretreatment. Within the tested pH range between 3 and 6, copper adsorption efficiency of NaOH-treated wood(96~99%) was superior to the HNO_(3)-treated wood(19~31%) and distilled water-treated wood(18~35%). The efficiency of copper removal by wood enhanced with increasing solution pH and reached a maximum copper ion uptake at pH 5~6. Adsorption behavior of copper onto both raw and HNO_(3)-treated woods was mainly attributed to interaction with carboxylic acid group. For NaOH-treated wood, carboxylate ion produced by hydrolysis or saponification was a major functional group responsible for Cu sorption. NaOH treatment of wood changed the ester and carboxylic acid groups into carboxylate group, whereas HNO_(3) treatment did not affect the production of functional groups which could bind copper. A pseudo second-order kinetic model fitted well for the sorption of copper ion onto NaOH-treated wood. A batch isotherm test using NaOH-treated wood showed that equilibrium sorption data were better represented by the Langmuir model than the Freundlich model.

신화적 관점에서 본 <박씨전> 소고

김나영 한국고소설학회 2003 古小說 硏究 Vol.16 No.-

<박씨전>은 작품을 구성하는 인물과 배경, 사건에 신이함이 짙게 배어 있는 작품 중의 하나다. 본 글은 그러한 작품의 신이함을 신화적 관점에서 바라보고자 하였으며 이를 탐색하는 과정에서 첫째, <박씨전>의 서사가 당신화의 서사 구성과 대응될 수 있음을 알 수 있었고 둘째, 박씨가 보여주는 여성신의 원초적인 특성과 후대의 변모된 특성을 통해 인간이 인식하는 여성신 형상의 변모를 추출할 수 있었다. 이러한 논의의 결과로 <박씨전> 서사 전개의 일관성과 서사 내적 삽화들의 유기적 필연성을 밝힐 수 있었으며, 더 나아가 현실의 불리한 상황을 역전시키고 怨望을 해소시켜 줄 수 있는 대상을 堂神의 존재에서 찾으려 했던 민중의 심리가 <박씨전> 서사 구성에 작용하고 있었음을 짐작할 수 있었다. 그럼에도 불구하고 <박씨전>은 박씨를 통해 시종일관 유교적 윤리규범과 그 논리를 강조함으로써 현실의 온리를 강조하고 있다. 이는 <박씨전>이 비록 현실의 원한과 소망을 '신의 이야기' 형식을 빌어 풀어내고 있지만 결코 그 허황함에 기대어 현실을 외면하여 병자호란과 같은 역사적 과오를 두 번 다시 되풀이하지 않기를 바라고 있기 때문이라 할 수 있다. Pakssijeon(<박씨전>) is one the works that novelty is being saturated with thickly in character, background, and case to constitute work. As for the writing, this researcher tried to look at such novelty of work from mythologic viewpoint. And in the course to research, this researcher could know that the narration of Pakssijeon is equivalent to the constitution of narration of then myths of village god(堂神話) firstly and could extract the transfiguration of female God from that human beings recognize through the original feature of female God that Mrs. Park shows and the transfigured feature of next period secondly. As the result of this discussion, this researcher could clarify the consistency of narration unfolding of Pakssijeon and the organic inevitability of illustrations inside narration and could guess that the psychology of populace who tried to find the subject to be able to reverse the disadvantageous situation of actuality and solve resentment from the existence of village god was acting in the constitution of narration of Pakssijeon. Nevertheless, Pakssijeon is emphasizing the logic of actuality by emphasizing Confucian moral norm and the logic consistently through Pakssijeon. It can be said that this is because Pakssijeon is expecting that historical mistake like the Chinese Invasion of Korea in 1636(丙子胡亂) may not be repeated even once more by leaning to vanity and turning away actuality, though Pakssijeon is solving the spite and wish of actuality by using the form of story of God.

Polyallylamine hydrochloride로 처리한 수피를 이용한 수용액상의 인 제거

양경민,김하나,김영관 강원대학교 산업기술연구소 2007 産業技術硏究 Vol.27 No.A

본 연구는 목재로서 활용가치가 적은 수피(bark)를 활용하여 수질오염물질을 제거할 수 있는 여과 시스템에 대한 기초연구로서 소나무의 일종인 loblolly pine(Pinus taeda L.) 수피의 인(PO_(4)-P) 흡착특성을 연구하였다. 실험에 사용된 수피는 입상형태로서 polyallylamine hydrochloride로 전처리하여 회분식 등온 흡착실험을 수행하였다. 회분식 등온흡착실험은 수용액 pH 3~pH 8범위에서, 인의 농도별(10, 20, 30, 40 mg/L)로 수행하였다. PH 5에서 가장 높은 인 제거 효율을 나타냈으며, 수용액의 pH는 실험 후 pH 3으로 감소하였다. 이러한 감소는 수피에 의한 phosphate의 흡착이 Lewis acid-base 반응으로서 이 과정에서 H^(+)의 방출로 인하여 나타난 현상인 것으로 여겨지며, 주된 반응 메카니즘은 더 연구할 필요성이 있다. 인 흡착은 초기에 빠른 속도로 진행되었으며 대략 200분 이후에 평형에 도달하였고, 시간이 지날수록 흡착양이 증가하는 경향을 보였다. 인의 흡착특성결과는 Langmuir 등온흡착식과 Freundlich 등온흡착식으로 설명될 수 있으며, 등온흡착식 적용결과, 흡착제에 대한 최대 흡착능은 7.14mg/g이며 다른 흡착제와 비교하여 더 높았다. 실험결과와 모델에 의한 흡착능을 비교 하고자 pseudo second-order model을 적용하여 흡착 동역학 상수를 구하였다. 또한 EDXA분석으로 회분식 흡착실험 후 수피와 인이 결합되어있는 것을 확인할 수 있었다.

Chitosan/oleamide Nanofluid for Enhancing Gas Utilization Efficiency in C1-gas Bioconversion

Eungsu KANG,Hyunsuk CHOI,Ji Yeong LEE,Min-sik KIM,Jeong Geol NA,Yoo Seong CHOI 한국생물공학회 2021 한국생물공학회 학술대회 Vol.2021 No.10

Microbial biotransformation using C1-gases (CH₄, CO) is a notable technique for sustainable, carbon-neutral chemical and fuel production. However, the low mass transfer coefficient (KLa) of C1-gases in biological processes has hampered the efficient production of value-added materials, despite efficient, nonnative strains having been recently developed. Here, we constructed a nanofluid material mainly composed of chitosan and oleamide (CS/OA), which was stably suspended with a particle size of 120.7 ± 39.0 ㎚ in aqueous culture media below pH 7.5. The kLa value was enhanced more than 1.5-fold with a reduction of surface tension even in the 0.0001 % (w/v) CS/OA nanofluid. In addition, when the nanofluid was applied into media for seed-cultivation of three C1-gas utilizing strains such as Methylomonas sp. DH-1, M. trichosporium OB3b, and Thermococcus onnurineus NA1 156T, the CS/OA nanoparticles attached to the cell surface, leading to a morphological change in the cell surface at extended lag-phase, and enhanced the specific cell growth rates (μmax), gas utilization efficiency in log-phase. Remarkably, the adapted strains from the seed culture using the CS/OA nanofluid media also had enhanced μmax in a subsequent subculture and the main culture using conventional culture media, resulting in higher C1 gas consumption, cell growth, and metabolite production such as formate and succinate. These results showed that the CS/OA nanofluid could be an effective medium component to enhance the gas utilization efficiency in C1-gas microbial bioconversion.Microbial biotransformation using C1-gases (CH₄, CO) is a notable technique for sustainable, carbon-neutral chemical and fuel production.

Social Contexts of Regulatory Policy and the Influence of Interests on Regulatory Sciences - On the Controversy on the Regulatory Policy on Alien Golden Apple Snails (Pomacea canaliculata) -

Na Yeong Kim,Ji Min Shin,Su Nam Cho 위기관리 이론과 실천 2020 Crisisonomy Vol.16 No.9

환경문제와 관련된 규제정책에는 다양한 사회적 맥락과 이해관계 당사자가 개입한다. 이 논문에서는 왕우렁이를 둘러싼 규제정책이 어떤 사회적 맥락 속에서 오랫동안 지지부진했으며, 그 속에서 관련 규제과학 연구는 어떻게 해석되고 활용되었는지를 살펴보았다. 이를 위해 20여 년간의 신문자료와 관련 부처 및 산하 연구 기관의 보고서 및 논문 등을 분석하였다. 왕우렁이를 둘러싼 규제정책은 국내외 상황 변화에 따른 정치, 경제적 맥락에서 자유롭지 않았으며, 규제과학의 실행과 해석 역시 환경부와 농림부 같은 부처의 이해관계와 무관하지 않았다. 국내에서 왕우렁이 문제는 복잡한 정치, 경제, 사회적 맥락 속에서 단순한 환경 문제를 넘어 복잡한 논쟁의 장 속에 놓이는 것이었다. 본 연구가 국내의 환경문제를 둘러싼 규제정책과 규제과학의 특징을 이해하고 보다 생산적인 논의가 이루어지는 데 기여할 수 있기를 기대한다. The regulatory policies related to environmental issues involve various social contexts and interested parties. We examined how the social contexts on Golden Apple Snail (Pomacea canaliculata) have made the regulatory policy sluggish for a long time, and how the regulatory science has been used and interpreted differently by each ministry of the central government in South Korea. We analyzed relevant newspapers, reports and papers of related ministries and affiliated research institutes over 20 years. The regulatory policy on Golden Apple Snail was not free from the political, economic, and social contexts influenced by international and domestic changes, and the implementation and interpretation of regulatory science were also related to the interests of ministries such as the Ministry of Environment and the Ministry of Agriculture and Forestry. This study is expected to contribute to understanding the characteristics of regulatory policies and regulatory sciences in particular domestic contexts.

Mitochondria-Targeting Chromogenic and Fluorescence Turn-On Probe for the Selective Detection of Cysteine by Caged Oxazolidinoindocyanine

Kim, Chae Yeong,Kang, Hyo Jin,Chung, Sang J.,Kim, Hyun-Kyung,Na, Sang-Yun,Kim, Hae-Jo American Chemical Society 2016 ANALYTICAL CHEMISTRY - Vol.88 No.14

<P>We report a chromogenic and fluorescence turn on probe based on crotonoyl ester-functionalized oxazolidinoindole for the selective detection of cysteine in neutral buffer. The probe rapidly formed indocyanophenolate through the Michael addition and a subsequent cyclization reaction of cysteine, inducing both a dramatic bathochromic shift (>130 nm) and a large fluorescence turn-on response (F/F-0 12) in the UV-vis and fluorescence spectra and affording a micromolar limit of detection (LOD = 5.0 mu M) of cysteine in HEPES buffer. When cysteine was added, the probe exhibited a dual optical change with strong green fluorescence and dramatic red color by the oxazolidinoindole-to-hydroxyethylindolium transformation. Further cellular application of the probe was successfully performed for the mitochondrial imaging of HeLa cells.</P>
