      • 人蔘 엑기스가 微生物의 生理에 미치는 影響 : 特히 酵母의 알콜醱酵와 Colony의 增殖에 관하여

        朱鉉圭 建國大學校附設 農業資源開發硏究所 1975 論文集 Vol.1 No.-

        乾燥酵母(saccharomyces cerevisiae)가 人蔘 Ex. 含量을 달리한 液體培地에서의 alcohol 醱酵에 미치는 影響과 酵母培養中의 colonical growth을 調査한 結果는 다음과 같다. (1) 醱酵中에 효모의 炭酸가스發生은 人蔘 Ex.를 넣은 시험구가 control 보다 빠르고 人蔘의 增量에 따라 醱酵時間은 점점 단축되며 人蔘 Ex 量 0.5,∼1.0%의 시험구에서는 가장 많은 炭酸가스 量을 보이고 5, 10 % 시험구에서는 炭酸가스 發生이 현저하게 抑制되었다. (2) 豫備培養의 時間이 30分의 효모보다 3時間의 효모가 炭酸가스의 發生時間이 半以下로 줄어지고 培養 3時間의 효모는 control 보다 인삼 처리구에서 발효가 촉진되었지만 抑制는 잘 나타나지 않았다. 그러나 30分間의 豫備培養酵母는 醱酵促進과 抑制가 뚜렷이 나타났다. (3) Dextrose 培地는 sucrose 培地보다 醱酵時間이 줄어지고 酵酵의 促進과 抑制作用은 dextrose보다 sucrose에서 잘 나타났다. (4) colony의 增殖速度는 人蔘 Ex.의 첨가량에 따라 다르고 1.0% 含量까지는 增加되지만 그 以上의 시험구에서는 增殖이 抑制되었다. (5) 6日間 alcohol 醱酵에서 alcohol 含量은 人蔘 Ex.의 첨가량 증량에 따라 계속 많아지고 抑制의 影響은 나타나지 않았다. The results of Ginseng extract effects on dry yeast(saccharomyces cerevisiae) are as follow. 1. Carbon dioxide was produced more rapidly in the treatments than in the control group. 2. Carbon dioxide production in one per cent ginseng extract added group was increased than other groups in which added 5% and 10% of ginseng extract. 3. The shorted time CO₂production group were D and E group in which 0.5∼1.0% of Ginseng extract were added. 4. Carbon dioxide production time was shortened in the group that has been fermented for three hours than the other group fermented for thirty minutes. Ginseng extract did not clearly effect on the three hours fermented group. 5. Fermentation time in the dextrose media was more shortened than in the sucrose media. Acceleration and inhibition of fermentation were more clearly shown in the sucrose media than in the dextrose media. 6. Colonial growth rate was accelerated in the one percent added group but inhibited in the 5% added group. 7. The amount of alcohol has been increased according to the content of ginseng extract for six days test and fermentation time was shortened according to the amount of ginseng extract.

        주현규,박미숙,사동민 선문대학교 첨단과학기술연구소 1998 첨단과학기술연구소 논문집 Vol.3 No.-

        청국장 첨가 식이가 흰쥐의 납 독성에 미치는 영향을 규명하고자 Sprague-Dawley 계(수컷,□)흰쥐의 60마리를 대조군과 납첨가군 및 4개의 청국장 첨가군(0.25, 0.50. 1.00, 1.50%)으로 나누고, 각 실험군당 10마리로 하여 8주간 방사하였다. 그때 Pb는 100ppm의 물로 섭취케 하였으며 사육기간 별로 흰쥐의 증체량, 식이 효율과 체내 각 조직 중의 Pb축적량을 분ㅅ jr하여 청국장의 Pb축적 완화 효과를 조사하였다. 1. 흰쥐의 증체량은 청국장 첨가량이 증가할수록 약간 많았는데 그중 T_(3)(1.00%), T_(4)(1.50%)군은 대조군(Tc)보다 각각 6.22, 3.86%가 높았다(p<0.05) 2. 식이 섭취량은 대조군에 비하여 T_(2)(0.50%), T_(3)(1.00%), T_(4)(1.50%)군이 각각 0.47, 6.66, 4.27% 증가되었다. 3. 청국장을 첨가한 실험군의 평균 물 섭취량은 대조군(Tc)과 거의 같았다. 4. 각 실험군간의 식이 효율은 T_(3), T_(4)군이 Tc군보다 극소한 증가를 보였다. 각 장기들의 무게는 실험구간에 일정한 경향을 보이지 않았으나 간 및 신장의 경우 대조군(Tc)에 비하여 T3, T4군은 5.95, 9.13%가, 신장에서 각각 11.49%, 18.00%가 높았다. 5. 흰쥐의 조직 중 축적된 납의 함량은 신장>뇌>시장>간>폐>근육>고환>비장>혈액의 순으로 높았다. 체모중 납 사육량은 사육 4주째가 납 축적량이 가장 많았고 그 이후에는 감소되었다. 청국장 첨가군은 대조군에 비하여 낮았고, 특히 청국장 1.00%이상의 첨가군이 비교적 낮은 함량을 보여, 납의 축적을 억제하는 효과가 있는 것으로 사료된다. This study was to investigate the effect of the addition of chungkukjang diet on lead toxicity of male rat (Sprague-Dawley family). There were divided into 6 different groups as follows : Control ; added lead group with 100ppm water; added chungkukjang of 0.25%, 0.50%, 1.00%, 1.50% respectively, and 10 white rats of each group were grazed for 8 weeks. The effect of chungkukjang on moderating lead accumulation was investigated by analysis of an increase in weight, diet efficiency, lead accumulation on each organ inside the body of rat. 1. The increment in weight of white rat was a little higher with increasing additional amounts of chungkukjang and T_(3), and T_(4) higher of 6.22% and 3.86% respectively than that of control group (Tc) with p<0.05 2. The amount of diet-intake was increased of 0.47, 6.66, 4.27% of t_(2), t_(3), T_(4) respectively, compared with control group (Tc). 3. The average amount of water-intake of treatment groups of additional chungkukjang was almost the same as control group (Tc). 4. The efficiency of diet of T_(3) and T_(4) was shown as a smaller increment than that of Tc. although the weight of each internal organs was not shown higher tendency regularly during the experimental period, it was shown higher of 5.95% and 9.13% in case of liver and 11.49% and 18.00% in case of kidney, respectively, compared with control group(Tc). 5. The contents of lead in the organs were as the following order : kidney > brain > heart > liver > lung > muscle > testis > spleen > blood. The content of lead accumulation was the highest in the fourth week of feeding and then it was decreased. The content of lead accumulation was lower in the additional chungkukjang groups compared with control and it was especially shown the additional group of over 1.0% chungkukjang was lower relatively, Therefore, the addition of over 1.0% chungkukjang would be an effect to inhibit the accumulation of lead.

        Effect of TiO_2 Nanotube Length on Photocatalytic Activity with Different Light Intensities: Cr[VI] Reduction and Hydrogen Production

        주현규,심은정,이재민,윤재경 한국수소및신에너지학회 2011 한국수소 및 신에너지학회논문집 Vol.22 No.4

        Anodized tubular TiO_2 electrodes (ATTEs) with three noticeably different lengths are prepared to determine their optimum length for the photo-driven activity in the reaction of Cr(VI) reduction and hydrogen evolution. The ATTEs with ethylene glycol have longer TiO_2 tubes (7-15.6 μm) than those with hydrfluoric acid (0.6-0.8 μm). These samples, which differ only in the length of the tubes, with a wall thickness of ca. 20 nm, consist mainly of an anatase crystalline phase after heat treatment at 650℃, since the anatase crystallites at the tube walls do not undergo transformation into rutile phase, due to the constraints imposed by the wall thickness. Among them, the medium size (ca. 8 μm) tubes provide the optimum conditions, irrespective of the light intensity, which is explained in terms of the correlation between the amount of photons and the adsorbed electron acceptors and their location. Photocatalytic Cr(VI) reduction leads to ca. 60% reduction of Cr(VI) even under 1 sun irradiation with the medium-sized anodized TiO_2 tubes, but only ca. 20% with the short- and long-sized tubes. For hydrogen evolution, tubes longer than 8 μm do not exhibit better performance with any light intensity.

        The Literary Inner Logic of Genesis 38 by means of Sexual Incontinence and Deception Motif

        주현규 한국신학정보연구원 2018 Canon&Culture Vol.12 No.2

        In Gen 37-50, the so-called Joseph cycle, an abrupt narrative shift takes place in Gen 38. The chapter does not follow the story of Jacob, Joseph, and Jacob’s other sons: Its narrative focus shifts away from Jacob and Joseph to Judah and Tamar, and two motifs -sexual incontinence and deception- are central to the narrative. And then, Gen 39 resumes the narrative flow of the Joseph cycle where Gen 37 leaves off. These narrative features raise interpretive questions: First, what is the purpose of the insertion of Gen 38 into that of Jacob and his sons? Second, why is the narrative of Judah and Tamar placed between Gen 38 and 39, not elsewhere in the Joseph cycle? To answer these questions, a number of scholars argue that Gen 38 is an individually contained narrative and that as a result, Gen 38 creates discontinuity within the narrative sequence of the Joseph cycle. According to them, it is the work of the final redactor who combined the diverse sources or traditions appearing to be in conflict. Others, on the opposite extreme, assert that Gen 38 exhibits clear cohesion and unity in its literary and theological context, even though it would be chronologically out of place. Thus, they say that there is considerable thematic, literary, and theological connection of Gen 38 to the chapters which surround it. In their view, the story of Judah and Tamar should not be excluded from Jacob’s “family history.” Agreeing in part with the argument that the story of Judah and Tamar is essential to interpret the larger narrative sequence of Gen 37-39 in the Joseph cycle, this study will suggest sexual incontinence and deception motifs construct the literary inner logic of Gen 38 and its theological implications. This study will also explore how Gen 38 canonically relates to its surrounding chapters.

        표고의 다공(多孔) 접종재배(接種栽培)에 의한 접종량(接種量)의 증가(원목(原木) $m^3$ 당 3.0kg - 6.0kg)가 균사(菌絲)의 초기 발육 상태인 활착(活着), 만연(蔓延)과 숙도(熟度) 그리고 우실체(宇實體)의 생산성(生産性)인 5년간 발생량과 개체당 중량에 미치는 영향을 조사한 결과 다음과 같은 결론을 얻었다. 1 다공(多孔) 접종재배(接種栽培)에 의한 종균(種菌) 접종량(接種量)의 증가는 종균(種菌) 활착율(活着率)에 영향을 주지 않았으며 균사(菌絲) 만연율(蔓延率)과 균사(菌絲) 숙도율(熟度率)을 증가시켰으며 결과적으로 자(字) 실체(實體)의 발생량도 증가되어 대조구인 골목$m^3$당 접종량(接種量) 3.0kg구의 발생량은 16.34kg/$m^3$이었으나 접종량(接種量) 6.0kg구에서는 7.7% 증가되어 17.60kg/$m^3$ 이었다. 2. 다공(多孔) 접종재배(接種哉培)에 의한 종균(種菌) 접종량(接種量) 증가는 자실체(字實體)의 조기 발생을 나타내었다. 자실체(字實體)의 2년차와 3년차의 건조 중량 발생량은 대조구인 골목 m3당 접종량(接種量) 3.0kg구는 5년간 발생량의 62.7%인 10.25kg/$m^3$인 반면 비교구인 접종량(接種量) 5.0kg구-6.0kg구는 74.0%-82.7%인 12.82kg/$m^3$-14.56kg/$m^3$으로 집중적으로 발생하였고 4년차와 5년차에서의 발생량은 급격히 감소하였다. 3. 표고 자실체(字實體)의 월별 발생량은 다공(多孔) 접종재배(接種栽培)에 영향을 받지 않았다. 자실체(字實體)는 5월-6월과 8월-9월 동안에 가장 많이 발생하였으며 발생량은 당해 년도 발생량의 11%-33%과 16%-28%를 각각 차지 하였다. 4. 다공(多孔) 접종재배(接種栽培)에 따른 접종량(接種量)의 차이에 의한 자실체(字實體) 개체당 평균 중량(건조 중량)은 일정한 경향이 없었으나 골목 $m^3$당 접종량(接種量) 4.0kg구가 1.63g로 가장 큰 것으로 나타났다. The effects of multipore spawn inoculation of Lentinus edodes on the mycelial growth stage and on the quantitative and qualitative yields of fruit-bodies for 5 years were investigated at natural environmental conditions. The spawn inoculation quantity did not affect the mycelial rooting at a range of 3.0kg-6.0kg per $m^3$ of bed-logs while the increase of spawn quantity by multipore inoculation increased the mycelial growth and the inner erosion of bed-logs, resulting in the increased yields of total fruit-bodies of L. edodes per $m^3$ of bed-logs for 5 years but resulting in the shortened major production period of fruit-bodies to the the first three years. Major production of fruit-bodies occurred during May-June and August-September, which was not affected by the spawn inoculation quantity. No significant differences in dry weight of a fruit-body were observed as increasing the spawn quantity by multipore inoculation; however the heaviest dry weight of a fruit-body was 1.63g at the spawn inoculation of 4.0kg per $m^3$ of bed-logs.
