This experiment was conducted to evaluate the characteristics of extruded rice flour, bread qualities of rice flour in blends with wheat flour and properties of the steam cooked rice bread for Korean rice varieties compared to the imported rice. Whiteness index and contents of crude fat and crude protein were higher in Korean rice varieties than in the imported rice, but the content of amylose was less than 20 percent in Korea varietes. Bread qualities score according to the 30% composition ratio of the extruded rice flour to wheat flour was inferior to the bread with only wheat flour in texture and color, but it was better in taste. Bread quality for rice varieties were good in order of Dongjinbyeo>Calrose>Dasanbyeo>Indian rice Panticle size of over 100 mesh was more in rice flour from the wet roller mill compare to the dry-pin mill in grinding methods. In amylogram characteristics, gelatinization temperature, peak viscosity, final viscosity were lower in rice flour from in wet roller mill than from the dry-pin mill. In varieties, Dongjinbyeo and Dasanbyeo were good for bread-making properties with lower value in amylogram charateristics. In score of the volume, hardness and taste for the steam cooked rice bread, the flour from the wet roller mill was higher than that from the drip-pin mill. In varieties, it was in order of Dongjinbyeo>Dasanbyeo>Calrose>Indian rice.

The contents to total ^32P, acid soluble-P, lipid-P and nucleic acid-P for the seedlings of rye, wheat, barley and naked barley treated with H_3^32PO_4 solution for 24 hours in 4℃ and 25℃ were determined in order to investigated the relationship beetween cold tolerance of barley and wheat varieties and contents of total-P and lipid-P. The results were summarized follows; 1. Total P contents(×10^2 cpm/g, DW) in the plants were in order of rye(148), naked barley(70), wheat(47) and barley(33). 2. The contents of total P and lipid-P in cold tolerant varieties of wheat barley and naked barley were increased, but those in cold sensitive vaieties were decreased, respectively. 3. The composition of acid soluble-P fraction was 80-90% for total P content and that of lipid-P and nucleic acid-P were less than 20% but the ratio of lipid-P was increased under low temperature(4℃) treatment, in contrast, that of nucleic acid-P was increased under high temperature(25℃). 4. The composition ratio of lipid-P under 25℃ in oat, wheat, barley and naked barley were similar with near 4.5%, but the ratio of that under 4℃ were different with 14.6% in rye, 12.6% in wheat, 7.4% in barley and 4.3% in naked barley with the degree of cold resistance.

유승호,이소영,김진세,변관수,정인과 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.5

연구목적 : 본 연구는 명백한 간성뇌병증이 없는 간경변증 환자에서 불안, 우울기분 및 삶의 질 등 정신과적 특징과 신경심리학적인 결손의 양상을 밝히기 위해서 고안되었다. 그리고 아임상적 간성뇌병증의 평가에서 체성감각 유발전위 검사의 역할을 연구하고자 하였다. 방 법 : 간경변증으로 진단된 41명의 환자군과 정상 대조군 31명을 대상으로 하였다. 이들에서 우울기분 및 불안을 평가하기 위해 Beck Depression Inventory와 State & Trait Anxiety Inventory를 시행하였고 삶의 질의 평가를 위해 Health-related Quality of Life Questionnaire를 시행하였다. 또한 어휘검사, 숫자외우기 검사, 토막짜기 검사, 숫자기호 바꿔쓰기 검사 및 선로잇기 검사 A와 B 등 간단하지만 포괄적인 인지기능검사를 시행하였다. 또한 41명의 환자군 중에서 인지기능검사 결과에 의거하여 분류된 13명의 아임상적 간성뇌병증군(SHE군)과 11명의 아임상적 간성뇌병증이 아닌 간경변증 환자군(non-SHE군) 그리고 8명의 정상 대조군에서 체성감각 유발전위를 측정하였다. 결 과 : 간경변증 환자는 정상인에 비해서 우울기분과 특성불안이 유의하게 증가하였다. 또한 건강과 관련된 일상생활의 삶의 질의 수준이 정상인보다 저하되었고, 특히 주의력과 각성이 요구되는 행동에서 수행이 저하되었다. 또한, 간경변증 환자는 숫자기호 바꿔쓰기 검사와 선로잇기 검사에서 정상 대조군보다 저하된 수행을 나타내었다. 또한 이러한 인지기능검사를 통해서 진단한 아임상적 간성뇌병증군에서 6개월 추적조사를 하였을 때, 명백한 간성뇌병증의 빈도가 아임상적 간성뇌병증이 아닌 군보다 유의하게 높았다. 체성감각 유발전위 소견은 N65 잠복기와 N20-N65 IPL의 경우 SHE군, non-SHE군 및 정상 대조군 사이의 유의한 차이가 있었다. 특히 N65는 SHE군만이 정상 대조군과 유의한 차이가 있었고 N95는 숫자기호 바꿔쓰기 검사 및 선로잇기 검사 A와 유의한 상관관계가 있었다. 결 론 : 간경변증 환자에게 우울 및 불안 등 정서적인 어려움에 대한 실제적인 관리 및 삶의 질을 높일 수 있는 치료적 접근이 고려되어야 하겠다. 또한 숫자기호 바꿔쓰기 검사와 선로잇기 검사가 아임상적 간성뇌병증의 조기 진단에 민감하고 유용한 도구로 생각되어 간경변증 환자에서 정례적으로 적용시키는 것이 간경변증 환자의 관리에 도움을 줄 수 있을 것으로 생각된다. 마지막으로, 본 연구에서의 체성감각 유발전위 소견은 간경변증 환자에서 아임상적 간성뇌병증 환자의 진단 및 연구에 중요한 의미를 지닌다고 생각된다. Objectives : This study was designed to elucidate the psychiatric characteristics and nature of the neuropsychological deficits associated with subclinical hepatic encephalopathy(SHE) in patients with non-alcoholic liver cirrhosis. And also the authors prospectively studied the role of somatosensory evoked potentials(SEP) in the assessment of SHE. Methods : Beck Depression Inventory(BDI) for measuring depression, State Trait Anxiety Inventory(STAI) for measuring anxiety, and Health-related Quality of Questionnaire(HQLQ) for measuring quality of life were administered the 41 non-encephalopathic liver cirrhosis patients(NELC) group and 31 carefully matched normal controls. And a prospective study to compare the performance of NELC group and normal controls on a short but comprehensive cognitive tests was conducted. After several cognitive, NELC group was divided into two groups, SHE group and non-SHE group by results of digit symbol substitution test(DSST) and/or trail making test(TMT) A and B. And then median nerve evoked cortical responses in 13 SHE patients group, 11 non-SHE patients group, and 8 normal controls were recorded for latencies of N13, P16, N20, P25, N30, P45, N65, and P95. And also responses for N13-N20 interpeak latency(IPL) and N20-N65 IPL were recorded. Results : There were significant differences between the NELC group and normal controls on BDI, trait anxiety scales in STAI, and almost all HQLQ except for the cognitive function, social interaction and life satisfaction(p<0.05). The NELC group exhibited poor performance in DSST, TMT A and TMT B compared with normal controls(p<0.05). As 17 NELC patients had abnormal cognitive test results, 41.5% of cirrhotic patients had SHE. In SEP assessment, NELC group with SHE and without SHE had higher N20-N65 IPL and only NELC group with SHE had higher N65 latency compared with normal controls(p<0.05). Conclusion : This study suggests that the patients with liver cirrhosis exhibit relatively selective deficits in complex attentional and fine motor skills, with preservation of general intellectual ability, memory, language and visuospatial perception. DSST, TMT A and TMT B seem to be useful screening tests for the detection of SHE. And also it is expected that late components and N20-N65 IPLs of SEP are helpful in the assessment of SHE.

대규모 연안개발에 따른 매립사업으로 연안역의 갯벌 또는 염습지 등의 연안생태환경공간은 해마다 감소하고 있다. 이에 따라 연안역 자연환경의 완화조치(Mitigation)의 일환으로 인공갯벌 및 염습지 개발의 필요성이 대두되어 활발한 연구가 진행되고 있으나, 인공 연안공간 조성시 복원정도의 정량적 평가에 관한 연구는 미흡한 실정이다. 따라서 본 연구에서는 연안 생태환경공간 조성지의 복원정도 평가에 대한 기초적인 연구로서, 준설토 배합비에 따라 구분되는 인공갯벌(Zone. P1) 및 염습지(Zone. P2) 현장시험구를 조성하여 생물화학적 환경인자인 시험구 내 대형저서동물 군집의 생물다양성과 개체수 및 생체량/식생(갈대)의 정착률/종속영양세균수/이화학적 특성(COD, IL, TN, TP, pH)에 대한 환경성 모니터링을 수행하였다. 이 결과를 바탕으로 각 환경인자들의 복원정도를 나타내는 복원지수를 제안하여 연안생태환경공간 조성에 따른 복원정도를 정량적으로 평가하였다. The ecological environmental zones in coastal area, like tidal flat and salt marsh, were gradually decreased due to large scale of coastal development projects, reclamation and so on. Therefore, the development of artificial tidal flat and salt marsh has been emphasized in coastal area as mitigation concept and studies on related this background has performed. But studies on the quantitative evaluation for degree of restoration were insufficient. In this paper, as a fundamental study for evaluation of restoration on the creation of ecological environmental zones in coastal area, it was conducted that the monitoring and experiment for bio-chemical factors (bio-diversity, population and biomass of macro-benthos, survival ratio of reed, the number of het-erotrophic bacteria and physico-chemical characteristics such as COD, IL, TN, TP and pH) using a in-situ pilot plant of tidal flat (Zone. P1) and salt marsh (Zone. P2), which was distinguished by content of dredged soil, in Jinudo, Nakdong estuary. From results of this study, the restoration index (RI), for evaluation concerning degree of restoration on the creation of ecological environmental zones in coastal area, was suggested and quantitative evaluation was performed using a restoration index (RI).

Volatile organic compounds (VOCs) are present in essentially all natural and synthetic materials from petrol to flowers. In this study, indoor and outdoor VOCs concentrations of houses, offices and internet-cafes were measured and compared simultaneously with personal exposures of each 50 participants in Asan and Seoul, respectively. Also, factors that influence personal VOCs exposure were statistically analyzed using questionnaires in relation to house characteristics, time activities, and health effects. All VOCs concentrations were measured by OVM passive samplers (3M) and analyzed with GC/MS. Target pollutants among VOCs were Toluene, o-Xylene, m/p-Xylene, Ethylbenzene, MIBK, n-Octane, Styrene, Trichloroethylene, and 1,2-Dichlorobenzene. Indoor and outdoor VOCs concentrations measured in Seoul were significantly higher than those in Asan except Ethylbenzene. Residential indoor/outdoor (I/O) ratios for all target compounds ranged from 0.94 to 1.51 and I/O ratios of Asan were a little higher than those of Seoul. Relationship between personal VOCs exposure, and indoor and outdoor VOCs concentrations suggested that time-activity pattern could affect the high exposure to air pollutant. Factors that influence indoor VOCs level and personal exposure with regard to house characteristics in houses were building age, inside smoking and house type. In addition insecticide and cosmetics interestingly affected the VOCs personal exposure. Higher exposure to VOCs might be caused to be exciting increase and memory reduction, considering the relationship between measured VOCs concentrations and questionnaire (p<0.05).

柳寅秀 단국대학교 1986 論文集 Vol.20 No.-

In order to invesgated the relationship between chining tolerance of rice varieties and their and phospholipid, those lipids from the rice plant in 5th-Leaf stage which conditioned in previous for 72 hours into the growth chambers controlled at 15℃ or 25℃ were isolated and thair fatty acid composition was determined. Kinds of strerols and fatty acid composition of total lipids were similar in the four varieties regardless of temperature, but fatty acid composition of phospholipid was different. Palmitic acid(35%), linoleic acid (37%) and linolenic acid (23%) were indentified as the major components of phospholipid, but only relative contents of palmitic acid and linoleic acid were changed with the temperature conditioning of rice plant. The ratio of unsaturated to saturated fatty acid increased from 1.55 at 25℃ to 2.04 at 15℃ for chilling-resistant varieties and decreased from 1.93 at 25℃ to 1.57 at 15℃ for chilling-sensitive varieties. As the results, the ratio of unsaturated to saturated fatty acid obtained from rice plant at 15℃ was higher in chilling resistant varieties(2.18 for Yeomyong byo, 1.91 for Cheolwon 34) than chilling-sensitive varieties (1.72 for suwon 312, 1.41 for Milyang). The phase transition temperature of liposomes prepared with phospholipid was much lower in chilling-resistant variety (14.0℃ for Yeomyong byo) than in chilling-sensitive variety (19.5℃ for Milyang 63).

저자들은 최근 8세 남아에서 대퇴부에 피하 결절로 발현한 피부 결핵 1예를 경험하였기에 이를 문헌 고찰과 함께 보고한다. Recently, the incidence of cutaneous tuberculosis is tending to decrease in Korea as well as in the world. However, the cutaneous tuberculosis is frequently reported in the developing countries having socioeconomic problems such as poverty, malnutrition, and poor environmental condition. In the western countries, it has recently become more resurgent because it occurs frequently in the immunocompromised hosts and in patients with AIDS. The clinical picture of all cutaneous mycobacterial infections including tuberculosis is highly variable, and any unexplained skin lesion, especially if it has nodular or ulcerative components, may be due to tuberculosis. We experienced a case of cutaneous tuberculosis in an 8 year-old Korean boy.

배인규,최선영,김양수,이미숙,오승준,류진숙,류지소,이희경,우준희 대한감염학회 2001 감염 Vol.33 No.2

Background : For the evaluation of infectious or inflammtory disease, Tc-99m HMPAO WBC scan has been used. But techniques involving radiolabelled leukocytes scan were difficult, and have failed to distinguish between bacterial infection and non-bacterial inflammation. To overcome this difficulty, we evaluated Tc-99m Ciprofloxacin in clinically suspected bacterial infection. Methods : We used this agent for 31 patients who had suspected sites of infection. And then we compared the imaging results of these patients with those of radiolabelled leukocyte scan. Results : There was no adverse effect. 29 patients was involved for the interpretation. Infective spondylitis was the most common suspected disease (41%). Bacteriologic culture was positive in 10 patients. The most common organism was meticillin-susceptible S. aureus (5 cases). The sensitivity and specificity of Tc-99m Ciprofloxacin was 83.3% and 66.6%, and those of Tc-99m HMPAO WBC was 62.5% and 83.3%, repectively. For the diagnosis of infective spondylitis the sensitivity of Tc-99m Ciprofloxacin was 80.0% and that of Tc-99m HMPAO WBC was 40.0%. Conclusion : Tc-99m Ciprofloxacin shows relatively high sensitivity and specificity. Tc-99m Ciprofloxacin was superior to Tc-99m HMPAO WBC for the diagnosis of infection in axial skeleton.

소목 천연 염색에 관한 연구 Ⅰ : 정제 알루미늄 화합물들의 매염효과에 대하여 Mordanting Effect of Purified Aluminum Compounds

권민수,전동원,최인려,김종준 服飾文化學會 2004 服飾文化硏究 Vol.12 No.5

Currently, as mordants, heavy metals are being used in dyeing process in order to improve dye uptake and dye fastness. These chemicals, however, are mostly harmful to human body and the environment along with the pollution by effluent. Traditionally, rice straw ash solution, lime, etc. have been used as mordants in order to improve the effects on dye uptake and color fastness of dyestuffs. The study of natural mordants would, therefore, be vital to the development and succession of our traditional dyeing methods. In this study, as a preliminary step toward the use of rice straw ash solution for the nautral dyeing using Caesalpinia sappan, several aluminum compounds were employed as mordants. When the purified aluminum compounds were used, on the basis of unmordanted cotton fabric, the WS values of the pre-mordanted and simultaneously mordanted fabrics increased by 2 or 3 times, while those of the post-mordanted fabrics decreased.

저자들은 아직 국내에 보고된 적이 없는 C. perfringens에 관한 간농양과 이에 동반된 전격성 패혈증으로 증상 발현 후 24시간 이내에 사망하였던 증례를 경험하였기에 보고하는 바이다. Clostridial infection usually occurred in association with trauma, malignancy, or intra-abdominal disease. Liver abscess by Clostridium perfringens is very rare and has not been reported in Korea .We experienced a case of liver abscess by C. perfringens in a 70-year-old man who was presented with fever. He developed a progressive jaundice and sepsis. Abdominal CT scan showed about 7×7 ㎝ sized liver abscess and gas formation within abscess. We underwent percutaneous drainage of a hepatic abscess and empirical antimicrobial therapy. The patient died less than 24 hours after presentation. C. perfnngens was identified from blood and aspirate of liver abscess.
