In order to develop a dandelion (Taraxacum officinale) with natural food applications, the effects of dandelion leaves and roots powder content on the physical, textural and sensory properties of sulggidduk were examined. Dandelion powders of leaves and roots at 0, 1, 2 and 3% were added to the dandelion sulgidduk. In the dandelion roots powder in sulgidduk, the color intensity of L values and the values and moisture content decreased however, the sensory color intensity, dandelion flavor and overall acceptability increased with increasing the dandelion powder content. The sensory overall acceptability indicated the dandelion roots powder content at 3% had the highest overall and flavor scores. As the dandelion leaves content was increased, the moisture contents, lightness, adhesiveness and cohesiveness of sulggidduk decreased, while the sensory color intensity, sensory hardness, hardness of texture properties and dandelion flavor increased. The addition at 1% of the dandelion leaves powder content with the dandelion sulggidduk and the addition at 3% of the dandelion roots powder content with the dandelion sulggidduk showed the highest overall acceptability.

The purpose of this study was to analyze consumers' awareness and satisfaction of open price system. Questionnaire survey was conducted from 3 September to 14 September 2011. We have surveyed 200 consumers who were living in Cheongju area. Major findings are as follows. First, consumers were not aware about open price system very well. The mean of the objectives and expected effects of open price system was 2.38. It means that many consumers when it comes to the open price system does not have the proper recognition was considered. Second, there was not big changes for consumers' information search behavior after execution the open price system. Third, consumers' satisfaction mean(m=2.32) of open price system was lower than dissatisfaction mean(m=3.40) of that. The main reason of dissatisfaction due to inconsistent pricing confusion was investigated. Fourth, there were statistic differences in open price system awareness and consumer behavior by consumers' socio-economics characteristics such as age, education, income, occupation, etc. Finally, consumers' satisfaction of open price system was influence by information search cost, product or brand image. On the other hand, consumers' dissatisfaction was only influence by open price system awareness.

Effect of Chlorella Diet Supplementation on Blood and Urine Cadmium Levels in Cadmium Poisoned Rats

김용호,--,--,--,--,-- THE KOREAN SOCIETY FOR BIOMEDICAL LABORATORY SCIEN 2003 Journal of biomedical laboratory sciences Vol.9 No.3

This study was conducted to investigate the influence of chlorella diet supplementation. Blood accumulation and urine excretion levels were measured after the Sprague-Dawley (SD) rats were fed on a chlorella diet supplementation mixed with 40 ppm of CdCl₂. Four groups tested for blood accumulation and urine excretion levels. All four groups fed on a basic diet with a cadmium mixture. The diet for the first group contained only basic diet and the cadmium added to the drinking water. The diet for the three other groups contained cadmium to the drinking water, and 1%, 5% and 10% of chlorella added to the basic diet. A concentration of cadmium for the first group showed a 3.2±0.4 ㎍/l blood accumulatior. level and 41.5±32.9 ㎍/l urinary excretion level, and the second group, which was fed on the basic diet with 1% of chlorella added and cadmium to the drinking water showed a 1.5±0.6 ㎍/l blood level and only 14.1±1.6 ㎍/l urinary excretion level. The other two groups, which were fed on 5% and 10% of chlorella concentration and cadmium to the drinking water did not exhibit any notable effects greater than the group fed on 1% concentration of chlorella. The results suggest that the blood accumulation and urinary excretion of Cadmium are influenced by the chlorella diet supplementation from the concentration of 1% of the basic diet.

禾穀類 種子 發芽時 호분층과 ??組織의 細胞壁에 多量 含有되어 있는 (1-3, 1-4)-β-glucan을 分解하여 種子의 發芽에 必要한 加水分解酵素의 分泌 및 擴散 浸透를 돕는다. 本 硏究에서는 國內 麥酒麥의 (1-3, 1-4)-β-glucanase 遺傳子의 構造 및 發現 에 대한 基礎 情報를 얻기 위하여 生化學的 및 分子生物學的 方法을 利用하여 發芽種子 및 어린 잎에서의 酵素活性과 遺傳子의 發芽樣狀 그리고 遺傳子의 構造 等을 調査하였다. 麥酒麥 發芽種子中 (1-3, 1-4)-β-glucanase 活性은 發芽 7日째에 제일 높았다. (1-3, 1-4)-β-glucanase의 活性測定에 使用한 (1-3, 1-4)-β-glucan이 (1-4)-β-glucanase에 의해 分解될 可能性이 있으므로 (1-4)-β-glucanase의 活性도 測定하였는데 (1-4)-β-glucanase의 活性이 매우 낮게 나타나서(1-4)-β-glucanase가 (1-3, 1-4)-β-glucanase을 分解하여 (1-3, 1-4)-β-glucanse의 活性에 影響을 미쳤을 可能性이 매우 낮았다. 麥酒麥의 (1-3, 1-4)-β-glucanase 遺傳子 構造를 PCR을 利用하여 調査하였던바 國內 麥酒麥의 (1-3, 1-4)-β-glucanase 遺傳子 構造는 外國의 다른 品種들이나 귀리의 遺傳子 構造와 대단히 類似하였다. 酵素活性 測定과 귀리의 (1-3, 1-4)-β-glucanase cDNA clone을 ?識子로 利用한 보리의 mRNA 分析에 의해서 發芽傳子 및 어린 잎에서 (1-3, 1-4)-β-glucanase가 種子發芽 以外에도 生育中인 組織細胞의 伸張과 發育 및 β-glucan 再利用에 泌要한 β-glucan 代謝에 關與하고 있음을 示唆하는 結果라 생각된다. (1-3, 1-4)-β-glucans hydrolysis of cell wall (1-3, 1-4)-β-glucanas accompanies degradation of endosperm cell walls during cereal seed germination. To investigate (1-3, 1-4)-β-glucanase expression pattern in Korean malting barley, (1-3, 1-4)-β-glucanase activity, gene structure and mRNA expression patterns werre examined. (1-3, 1-4)-β-glucanase activity increased as germination proceeded and the highest enzyme activity was detected in seeds germinated for 7 days. Because (1-4)-β-glucanase have a potential to degrade (1-3, 1-4)-β-glucans, (1-4)-β-glucanase activity was also determined. (1-4)-β-glucanase activity, however, was very low minimizing possibility of (1-4)-β-glucanase action on (1-3, 1-4)-β-glucan substrate. PCR technique was employed to investigate (1-3, 1-4)-β-glucanase gene structure. The amplification product of the expected size from the targeted sites of Dusan #29 indicated that (1-3, 1-4)-β-glucanase systems were conserved in different barley varieties and even in oats. (1-3, 1-4)-β-glucanase activity and mRNAs were detected in young leaves as well as in germinating seeds. This may suggest that (1-3, 1-4)-β-glucanase are also involved in β-glucan metabolism required for cell elongation and β-glucan reutilization during leaf growth and developmetn.

석청에 포함된 grayanotoxin에 의해 독성 작용이 나올 수 있으며, 이러한 독성 작용은 일반적으로 24시간 이내 저절로 회복된다. 최근에 본 저자들은 석청 복용 후 발생한 심실빈맥을 경험하였기에 보고하는 바이다. 49세 남자가 호흡곤란으로 내원하였으며, 내원당시 분당 40회 정도의 동성 서맥이 관찰되었고, 수액을 투여하던 중 심실 빈맥이 발생하였다. 항부정맥제를 투여 후 정상 동율동으로 전환되었으며, 특별한 이상 없이 4일 후 퇴원하였다. Mad-honey intoxication caused by the consumption of honey producted from the nectar of rhododendrons. The grayanotoxins cause the intoxication. The toxic effects of mad-honey poisoning are rarely fatal and generally last for no more than 24 hours. We experienced one case, a 49 years-old man who presented with dyspnea after ingestion of mad-honey. He showed marked sinus bradycardia with < 40 beats per minute on admission. The cardiac rhythm was changed to ventricular tachycardia immediately. These features resolved completely in 24 hours with continuous infusion of amiodarone(600 mg per day) and fluids. We report the case of intoxication of mad-honey as a presentation of fatal cardiac arrhythmia.

유아교사의 소진에 관한 연구

유경숙,김수옥 한국아동교육학회 2004 아동교육 Vol.13 No.2

본 연구에서는 광주광역시 유아교사의 소진경험에 대해 체계적으로 분석하고 검토해 봄으로서 유아교사의 전문성을 신장하고 유아교육의 질적 향상에 기여하고자 한다. 근무시간에 따른 소진에서는 12시간 이상 근무하는 집단이 가장 소진한 것으로 나타났다. 즉 평균 이상의 시간을 근무하는 경우 소진하는 것으로 볼 수 있는데, 이것은 근무시간이 긴 교사들은 정서적 고갈의 소진 증상을 자주 느끼고 일에서 성취감도 적게 느끼는 것으로 보아 개인적인 특성 요인들보다 근무여건이 소진에 더 절정적인 영향을 미치는 것으로 여겨진다. 본 연구의 대상인 광주지역 유아교사들의 평균 근무시간은11시간으로 나타났으며, 근무시간이 길어질수록 일에 대한 집중력이 털어지므로 교사의 스트레스로 작용하여 소진이 높게 나타나는 것으로 해석된다. The purpose of this study was to find the difference among child teachers' exhaustion A questionnaire was distributed to 278 child teachers who worked in Nurseries and Kindergartens at Kwangju. The questionnaire consisted of 13 questions regarding teachers' background and exhaustion. To find exhaustion by the background variables of child teachers, t-test, One-way Anova, and Scheffe-test were used The result was as follows; Child teachers' exhaustion found a significant difference by formal schooling and average hours of duty. The higher exhaustion was found in a group of child teachers who completed not more than a college, a group of those who finished a graduate school, and a group of those who worked for more than 12 hours in average.

칼만증후군(Kallmann's Syndrome) 1례

김용성,백승훈,유경훈,구기선,형근영,김경년,조정구 圓光大學校 醫科學硏究所 1997 圓光醫科學 Vol.13 No.1-2

Kallmann's syndrome is the most common form of isolated gonadotropin deficiency, characterized by hypogonadotropic hypogonadism due to GnRH deficiency, delayed puberty and smelling difficulty. It occurs sporadic or familial pattern, and the mode of inheritence has not been fully documented. The defect in patient of Kallmann's syndrome occurs at suprapituitary level involving mechanism that regulate GnRH synthesis or release, so this syndrome classified as a secondary hypogonadotropic hypogonadism. The gonadotropin or pulsatile GnRH administration enable successful stimulation of spermatogenesis and fertility. We have experienced 1 patient with Kallmann's syndrome and presented with the review of the literature.
