해양 심층수는 일본, 미국 등에서 200m 이하의 심해에서 취수되고 있으며, 물의 특성으로 부영양성, 저온안정성 및 청정성을 들 수 있다. 본 연구에서는 발효빵의 효모증식에 대한 해양 심층수와 그 염의 효과에 대해 조사하였다. 해양심층수와 심층수염을 첨가하여 발효한 빵의 부피증가율은 증류수만을 사용한 빵보다 높게 나타났다. 또한 해양 심층수를 이용한 식빵의 기공 형태는 증류수로 제조된 식빵의 기공보다 둥글고 일정하였다. 한편, 식빵의 전반적인 기호도에서 증류수와 심층수염을 혼합하여 첨가한 식빵이 6.56으로 가장 높은 관능평점을 나타내었다. Deep seawater in pumped up about 200 m water depth, which has characteristics of rich nutrients, low temperature and cleanness. This study was performed to investigate the effect of deep seawater and deep seawater salt on the yeast growth of fermented bread. The rate of increase in volume of groups added with deep seawater and deep seawater salt was higher than that of groups added with distilled water. The pore pattern of groups added with deep seawater was more regular than that of groups added with distilled water. In sensory property, the bread added with distilled water and deep seawater salt has the highest score (6.56) in overall acceptability.

김미림,정지숙,이기동 한국식품저장유통학회 ( 구 한국농산물저장유통학회 ) 2003 한국식품저장유통학회지 Vol.10 No.3

해양 심층수 첨가에 따른 효모 발효력과 심층수 첨가 최적 농도를 알아보기 위하여 효모균주 9종에 대하여 증식을 조사하였다. 효모균주는 Saccharomyces cerevisiae 10호, 11호, 12호, 901, RCY, Saccharomyces kluyvery DJ97, Saccharomyces cerevisiae YJK, JK99, CMY-28 등이었으며, 해양 심층수는 경도 250, 500, 1000으로 조절하였고, 대조군과 함께 증식력을 측정하였다. Saccharomyces cerevisiae 12호, 균주가 심층수 경도 500인 시험군에서 증식력도 높았으며, Sacch cereviwiae 901에서는 경도 1000인 시험군이 대조군에 비해 증식력이 높게 나타나 효모균주의 종류와 심층수의 첨가량에 따라 적응력이 강한 균주가 있었다. 당농도와 심층수 첨가량에 따른 Sacch cereviwiae kluyvery DJ97의 발효력은 심층수 경도 200의 당 10% 첨가군에서 가장 잘 증식하였다. In order to study optimum culture condition of yeast medium added deep seawater, we examed samples with 9 yeast strains. The growth rate growth rate were measured for Saccharomyces cerevisiae 10, 11, 12, 901 and RCY and Saccharomyces kluyvery DJ97, Saccharomyces cerevisiae YJK, JK99, CMY-28 etc. The growth of S. cerevisiae 12 was found most active in the deep seawater(hardness 500). The growth rate of S. cerevisiae 901 on medium containing deep seawater(hardness 1000) was faster than that of the yeast on medium without deep seawater. The use of deep seawater on the growth of Sacch.cerevisiae kluyvery DJ7 revealed maximum groth under the condition of hardness 200 of deep seawater and 10% of sugar concentration.

Effects of Sucrose, Phosphate, and Calcium Carbonate on the Production of Pikromycin from Streptomyces venezuelae

( Jeong Sang Yi ),( Min Suk Kim ),( Sung Jin Kim ),( Byung Gee Kim ) 한국미생물 · 생명공학회 2015 Journal of microbiology and biotechnology Vol.25 No.4

Polyketide secondary metabolites share common precursor pools, acyl-CoA. Thus, the effects of engineering strategies for heterologous and native secondary metabolite production are often determined by the measurement of pikromycin in Streptomyces venezuelae. It is hard to compare the effectiveness of engineering targets among published data owing to the different pikromycin production media used from one study to the other. To determine the most important nutritional factor and establish optimal culture conditions, medium optimization of pikromycin from Streptomyces venezuelae ATCC 15439 was studied with a statistical method, Plackett-Burman design. Nine variables (glucose, sucrose, peptone, (NH4)2SO4, K2HPO4, KH2PO4, NaCl, MgSO4·7H2O, and CaCO3) were analyzed for their effects on a response, pikromycin. Glucose, K2HPO4, and CaCO3 were determined to be the most significant factors. The path of the steepest ascent and response surface methodology about the three selected components were performed to study interactions among the three factors, and the fine-tune concentrations for maximized product yields. The significant variables and optimal concentrations were 139 g/1 sucrose, 5.29 g/l K2HPO4, and 0.081 g/l CaCO3, with the maximal pikromycin yield of 35.5 mg/l. Increases of the antibiotics production by 1.45-fold, 1.3-fold, and 1.98-fold, compared with unoptimized medium and two other pikromycin production media SCM and SGGP, respectively, were achieved.

멀티턴 루우프형 센서를 이용한 3차원 ELF 자장측정계

길경석,안창환,박동화,이복희,이정기 한국센서학회 1996 센서학회지 Vol.5 No.2

With the three dimensional magnetic field measuring system dealt with in this paper, accurate measurements and analyses of extremely low frequency(ELF) magnetic fields caused by starting and/or operating electric devices and power installations can be conducted. To obtain high performance for lower frequency and spatial components without any distortion, the measuring system is designed as three dimensionally including the multiturn loop-type magnetic field sensors, differential amplifiers and active integrators. As the results of calibration experiments, the frequency response characteristics of the measuring system range from 8[Hz] to about 53[kHz] for each direction of x, y, z axes, and the response sensitivities are 9.54, 9.21, 10.89[mV/μT], respectively. The actual survey experiments by using an oscillating impulse current generator confirm a reliability of the proposed measuring system. Also, through the other experiments by using small-sized induction motors, the magnetic field intensities when starting and steady-state operating mark 15.8, 8.61 [μT] as maximum value, respectively. And those intensities decrease steeply according as the measuring distance increases.

이 연구의 과제는 지능과 창의성의 관계를 탐색하는 것이었다. 연구의 과제로부터 세 가지의 연구문제를 도출한 후에 다중지능, 성공지능, 정서지능 등 세 가지 지능과 창의성의 관계구조를 복합적으로 분석하였다. 연구대상은 인문계 고등학교 1학년 학생 204명(남학생 97명, 여학생 107명)이었다. 측정은 박병기·강현숙(2006)의 통합창의성 척도, 문용린·류숙희·김현진·김성봉(2001)의 다중지능검사, 박도순·하대현·성태제(2000)의 성공지능검사, 문용린(1997)의 정서지능검사를 활용하였다. 지능과 창의성의 관계구조는 정준상관분석을 적용하여 분석하였다. 연구의 결과, 지능과 창의성의 관계는 지능의 종류에 따라 차이가 있었다. 다중지능과 창의성은 ``동등한 포섭``에 가까울 정도로 강한 중첩관계를 보여주었으며, 정서지능과 창의성은 중간자적 보통의 중첩관계를 맺고 있었고, 성공지능과 창의성은 ``실질적 독립``에 가까운 중첩관계를 나타냈다. 지능과 창의성의 관계구조에 성별 차이가 있는지 살핌으로써 일반화 가능성을 검토하였다. 지능과 창의성의 세 가지 관계구조는 정준계수, 정준(교차)부하량, 정준상관(자승), 공유분산, 정준중복지수, 성별 차이 등의 측면에서 자세하게 비교되었다. 연구의 의의, 시사점, 제한점, 그리고 후속연구를 위한 제안이 논의되었다. The purpose of this study was to explore the relationship between intelligence and creativity. This purpose was differentiated into three research questions of which the key task was to explore the relationship structure between three kinds of intelligence and creativity. Three kinds of intelligence included multiple intelligence, successful intelligence, and emotional intelligence. The subjects of this study were the 204 high school students in the first grade. Instruments of integrative creativity by Bak & Kang(2006), multiple intelligence by Moon et al.(2001), successful intelligence by Park, Ha, & Seong(2000), and emotional intelligence by Moon(1997) were utilized. The canonical correlation analysis was the main statistical method. Result showed that the relationship structures were different according to the types of intelligence. Multiple intelligence showed very high relationship with creativity, emotional intelligence showed middle relationship, and successful intelligence displayed very low relationship. Gender differences of relationship structure were analysed as a tool for investigating generalizability. Three kinds of relationships were compared in detail through the criteria of canonical weights, canonical (cross) loadings, canonical correlation (squared), shared variances, redundancy indices, and gender differences. Significance, implications, limitations, and suggestions for the future study were discussed.
