Effects of mustard seed(Brassica juncea) on the preservation of raw gizzard-shad slice were investigated, morphological change of Vibrio parahaemolyticus treated with water-extract of mustard seed was examined, the results are as following. The pH of raw gizzard-shad slice soaked in water with mustard seed slightly increased during preservation, and the pH was in inverse proportion to the added amount of mustard seed. The number of bacteria and Vibrio of raw gizzard-shad slice treated with mustard seed were lower than control, and the higher the mustard seed concentration, the lower the number of bacteria and Vibrio. The TMA-N content of raw gizzard-shad slice gradually increased during preservation, and the TMA-N was in inverse proportion to the added amount of mustard seed. Scanning electron microscopy of Vibrio parahaemolyticus treated with water extract of mustard seed showed that surface membrane was destroyed with expended ellipsoidal shape.

연구목적 : 저자들은 태생기 동안에 받는 유전외적 요인, 즉 환경적 요인이 산발성 정신분열병 환자들의 발병에 크게 관여할 것이라고 가정하였다. 이를 검증하기 위하여 형제 중 1인 이상이 발병하여 가족력을 분명히 알 수 있는 정신분열병 환자군(이하 형제 환자군)과 가족력이 없는 산발성 정신분열병 환자군(이하 산발성 환자군) 및 정상대조군을 대상으로 산과적 합병증, 신체미세기형 및 정신분열병의 임상 양상을 비교하였다. 방 법 : 연구 대상은 형제 환자군 43명(남 22명, 여 21명), 산발성 환자군 43명(남 23명, 여 20명), 정상대조군 43명(남 20명, 여 23명)이었다. 산과적 합병증은 Lewis 척도를 이용하여 평가하였고 신체미세기형은 Waldrop 척도를 이용하여 측정하였다. 임상 양상으로서 발병 연령, 병전 기능 수준, 정신병리, 약물에 대한 반응, 회복시의 전반적 기능 수준, 지연성 운동장애의 유무를 평가하였다. 결 과 : 정상대조군과 정신분열병 환자군 전체를 비교하였을 때 산과적 합병증과 신체미세기형의 총점과 각 소항목의 점수에 차이가 없었다. 산발성 환자군과 형제 환자군을 비교하였을 때 산과적 합병증의 전체 점수에서는 유의한 차이가 없었으나, 출생 당시에 태아가 받은 스트레스 항목의 점수가 산발성 환자군에서 유의하게 높았다. 신체미세기형에서는 전체 점수 및 입의 미세기형 점수가 산발성 환자군에서 유의하게 높았다. 신체미세기형의 전체 점수가 4점 이상인 환자수도 산발성 환자군에서 높은 경향성을 보였다. 산과적 합병증과 신체미세기형 사이의 상호 연관성은 찾을 수 없었다. 정신분열병의 임상 양상 중에서는 Krawiecka 척도의 총점 및 양성 증상 점수와 회복시의 전반적 기능 수준만이 형제 환자군에 비해 산발성 환자군에서 유의하게 높았다. 성별에 따라서는 형제 환자군에서 남자 환자의 산과적 합병증이 유의하게 높았다. 결 론 : 본 연구를 통해 산과적 합병증 및 신체미세기형 연구가 정신분열병의 원인을 규명하기 위한 유용한 방법임이 시사되었지만, 가족력, 산과적 합병증 및 신체미세기형의 관련성에 대해서는 분명한 결론을 내리지 못하였다. The authors hypothesized that sporadic schizophrenic patients had more chances of receiving environmental insults during the fetal neural development compared with familial schizophrenics. We tested our hypothesis by comparing obstetric complications(OCs), minor physical anomalies(MPAs) and other clinical features, and examining the correlation between OCs and MPAs in schizophrenic patients who had one or more sibling with schizophrenia(sibling group) and sporadic schizophrenics(sporadic group) and normal controls. OCs were evaluated by the scale of Lewis, and MPAs were measured by the Waldrop scale. There were no significant difference in OCs and MPAs between schizophrenic and control groups. Sporadic group had significantly higher fetal distress, total Waldrop score and Waldrop score for mouth than sibling group. And there was a tendency that the number of subjects having the Waldrop score over 4 points was greater in the sporadic group. No significant correlation was observed between CCs and MPAs. The scores of initial psychopathology and post-treatment functioning were much higher in the sporadic group, but the other clinical feature showed no difference. Although male patients had more OCs than female patients in sibling group, no sex difference were observed as a whole. Our results suggest that, if the methodological weakness were complemented, OCs and MPAs would be useful tools in the search for the cause of schizophrenia.

토마토 ‘모모타로’를 공시하여 셀레늄 10㎎ㆍL?¹의 관주 및 엽면시비 등의 단용 및 혼용처리가 수경재배 토마토의 생육 및 과실 내 셀레늄 축적 함량에 미치는 영향을 구명하였다. 토마토 종자를 50공 트레이에 파종하여 70일 동안 육묘한 후 유묘를 코코피트 슬라이브를 이용한 수경재배 시스템에 정식하였다. 양액은 일본원예시험장 배양액 표준처방으로 조성하였으며, pH 5.8~6.2와 EC 2.3 ㎎ㆍL?¹ 등으로 조절하여 공급하였다. 셀레늄은 무기태 SeO₂와 sugar fatty acid ester에 킬레이트화 한 유기태 셀레늄을 10 ㎎ㆍL?¹으로 조성하여 관주, 엽면시비, 관주와 엽면시비를 병행하여 처리하였다. 초장, 엽수, 엽면적 및 엽록소 등의 토마토 생장반응은 셀레늄의 엽면시비, 그리고 엽면시비와 관주를 병행한 처리구에서 현저히 증가하였다. 과실 내 셀레늄 축적 함량은 킬레이트화 한 유기태 셀레늄을 엽면시비와 관주를 병행하여 처리한 경우에 0.302 ㎎ㆍL?¹으로 가장 높았다. 무기태와 유기태 셀레늄의 엽면시비와 관주 등의 단용 처리 보다는 혼용 처리가 전반적인 과실 생장과 체내 셀레늄 축적에 효과적이었다. 무기태 설레늄(SeO₂) 보다는 sugar fatty acid ester에 킬레이트화한 유기태 셀레늄 처리가 셀레늄을 함유한 기능성 토마토의 수경재배에 더 효과적이었다. This study was conducted to clarify the effects of supplying methods of selenium on the growth and Se uptake of hydroponically grown tomato plants. Tomato seeds (Lycopersicum esculentum Mill. cv. Momotaro T-93, Daki Seed Co.) were sown in plug tray with fifty holes, and raised for sixty days. Tomato seedlings transplanted to coco fiber slabs were supplied with the nutrient solutions adjusted to EC 2.3 dSㆍm?¹ and pH 5.8~6.2 recommended by the Japanese Horticultural Experiment Station. Selenium forms used were inorganic SeO₂ (here in after referred to Se) and organic selenium chelated with sugar fatty acid ester (here in after referred to chelated-Se). 10 ppm selenium solutions were treated to tomato plants with foliar applications, drenching, and foliar application plus drenching. Growth characteristics in terms of plant height, number of leaves, leaf area and chlorophyll content were significantly increased in the plot of foliar application of Se, and in the plot of foliar application plus drenching of chelated-Se than other plots, respectively. Transported contents of selenium into the tomato fruits were highest as 0.302 ppm in the plot of foliar application plus drenching of chelated-Se. Also, it had tended to be higher in the plot of foliar application plus drenching than in the plots of foliar application or drenching in both of Se and chelated-Se. Foliar application and drenching of organic chelated-Se were effective to produce the functional tomato fruits.

영역별 대역비를 이용한 인공위성 화상데이타의 압축

서용수,김영춘 東西大學校 1996 동서논문집 Vol.2 No.1

본 논문에서는 영역별 대역비와 벡터 양자화를 이용한 다중분광 인공위성 화상데이터의 효율적인 압축 기법을 제안하였다. 제안한 기법에서는 다중분광 인공위성 화상데이타의 각 대역별 특성에 따라 화소들을 영역별로 분류한다. 분류된 영역별로 기준 대역에 대한 각 대역의 비를 구한 후 대역내 및 대역간 중복성을 제거하기 위하여 각 분류 영역에 대하여 대역내 벡터 양자화 및 대역간 벡터 양자화를 행한다. 또한, 대역간 벡터 양자화의 오차를 줄이기 위하여 각 대역별 오차화상(residual image)에 대하여 다시 대역내 벡터 양자화를 행함으로써 화질을 향상시킨다. 즉, 벡터 양자화를 각 분류 영역 단위로 행함으로써 화상에 존재하는 많은 중복성이 제거되어 압축효율이 향상된다. In this paper, we propose multispectral satellite image compression method using band ratio for each classified region and vector quantization(VQ). Each pixel vector is classified by considering band characteristics of multispectral satellite images. For each classified pixel vector, band ratio is calculated from the feature band. We perform intraband(spatial) VQ for feature band and interband(spectral) VQ for band ratio to remove spatial and spectral redundancy, respectively. Residual Vq for error images are also performed to reduce error of interband VQ. Thus, this method improves compression efficiency because of removing both intraband and interband redundency in multispectral satellite images, effectively. Experiments on Landsat TM(Thematic Mapper) multispectral satellite image show that compression efficiency of the proposed method is better than that of conventional method.

The enzyme, squalene synthase, represents a branch point in the isoprenoid pathway capable of diverting carbon flow specifically to the biosynthesis of phytosterol and Triterpenoid. Transgenic Eleutherococcus senticosus plants were prepared by introducing the genes for squalene synthase derived from Panax ginseng (PgSS1), hygromycin phosphotransferase (HPT) and green fluorescent protein (GFP) through Agrobacterium-mediated transformation. Establishment of transgenic plantlets were confirmed by the presence of PgSS1 and HPT bands in the genomic DNA preparation using a PCR method and a Southern blotting. In addition, expression of the introduced GFP DNA was confirmed by observing green fluorescence of GFP from the embroyos. In the in vitro analysis of the PgSS1 enzymatic activities the transgenic plants showed to have 1.5 to 3 times higher than wild type plant, indicating that the PgSS1 genes was well over-expressed in the transgenic plants. Especially the PgSS1 acivities of embroyogenic cell was 120 times higher than those of plantlet.

In this paper, we fabricated optical telemetry IC chip using CMOS process. The telemetering IC with the size of 4 ×4㎟ has the following functions: receiving of command signals, initialization of internal state of all functional blocks, decoding of subject-selection signal, time multiplexing of 4-channel modulated physiological signals, transmission of telemetry signal to extemal system, and auto power down control. The designed synchronous oscillator with low supply voltage dependence operates at a supply voltage from 4.6V-6.0V. And the nonlinearity error of PIM modulator was less than 1.2%FS. In order to demonstrate the principle operations of the implemented CMOSIC chip, the experiments of biotelemetry was performed by telemeter unit and external unit. Main features of this system are to select one of the 4 subjects, to enable measurement of biological signals using the same optical signal, and transmit them back to the extemal unit.

多層膜의 多重干涉에 의한 磁氣光學效果에 關한 硏究

徐龍源 대구보건대학 1996 대구보건대학 論文集 Vol.16 No.-

I examined on the magneto- optical effect by media of a TM/NM multiple layered film, and has been carried out Kerr angle, ellipticity, reflectivity by graphs through the computer simulation and compared them to their experimental value. As I compared each layer's materials and their thickness, find out the bigger magneto-optical effect than having another condition. I am also able to find out some materials giving better reliance of S/N ratio in determinig the refractive index and thickness. It is regretted that could not calculate more close value than the experimental value that may be able to obtain. If should be simulated accurate value of optical constant each wavelength. The results of simulation are as follows. 1. In case of single layer film of Co or Fe, there are big difference between experimental and theoritical value in the range of short wevelength. 2. In case of Co/Pd,the reliance of composition, the variable tendency of magneto-optical kerr rotaition angle for Co thickness is fully corespond to experimental and theoritical value. 3. In case of Fe/Cu and Fe/Ag, magneto-optical Kerreffect in the near Cu and Ag absorption band correspond to experimental and theoritical values than the Fe single layer that has tendency of increasing. 4. In case of TM/NM multilayer, Magneto-effect by refraction of multilayer connecet with the absorption band of NM closely.
