쑥 분말의 첨가량을 달리하여 양갱을 제조한 후 이화학적 특성 및 관능적 특성을 알아보았다. L*값과 b*값은 유의적으로 감소하였고(p<0.05), 반면 a*값은 점차 증가하는 경향을 나타내었다. 양갱의 경도(hardness), 점착성(gumminess), 씹힘성(chewiness) 및 응집성(cohesiveness)은 쑥 분말의 첨가량이 증가할수록 증가하는 경향을 보였고(p<0.05), 탄력성(springiness)은 유의적으로 감소하는 경향이 나타났다(p<0.05). 항산화활성을 나타내는 총 폴리페놀 함량과 전자 공여능은 쑥 분말 첨가량이 증가함에 따라 유의적으로 증가하는 경향을 나타내었고(p<0.05), 전자공여능에서 보다 현저한 증가를 보였다. 소비자 검사결과 2% 첨가군이 모든 평가항목에서 유의적으로 높은 평가를 받아 양갱의 관능적 품질을 최대한 유지하면서 쑥 분말의 기능적 잇점을 최대한 활용하기 위한 최적 첨가농도는 2%가 가장 적합한 것으로 판단된다. The feasibility of incorporating mugwort powder as a value-added food ingredient in food products was investigated using yanggaeng as a model system. Mugwort powder was incorporated into yanggaeng at 0, 2, 4, 6, and 8% (w/w) levels by adding mugwort amounts based on the total weight of bean sediment. Lightness and yellowness significantly decreased but redness gradually increased. Hardness, gumminess, chewiness, and springiness increased with higher amounts of mugwort powder added in the formulation. Total polyphenol content and 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging activity were significantly influenced by the higher amounts of mugwort powder in the formulation. The highest level of incorporation (8%, w/w) had a considerable adverse effect on consumer acceptance in all attributes. Yanggaeng containing 2% mugwort powder is recommended for overall acceptance, as well as the functional properties of mugwort powder, without sacrificing consumer acceptability.

This study was conducted to investigate the effects of Tissue Culture Medium 199 (TCM) and Dulecco's Modified Eagle Medium (DMEM) on the blastulation and grade of human oocytes on Vero cells in vitro. A cohort of 79 and 93 oocytes in metaphase II stage were used in TCM 199 and DMEM respectively. No differences were found in the numer of oocytes showing two-pronuclei between TCM (82.3%) and DMEM (86.0%). The number of fertilized oocytes reaching the blastocyst was not significant in TCM (60.0%) and DMEM (63.1%). A total of 89 blastocysts were categorized into the four grades (BG1, BG2, BG3 and early) depending on their morphology. The number of embryos achieving the blastocyst grade 1 (BG1) was significantly higher (p<0.05) in DMEM (50.8%) than TCM (15.0%). It is concluded that cultured oocytes in DMEM with glutamine on Vero cells should be significantly increased BG1.

Objective: Juvenile dermatomyositis (JDM) is a multisystemic inflammatory disease in which the muscle, skin and gastrointestinal tract are prominently involved. It is characterized early in its course by microvasculopathy of varying severity and later by the development of calcinosis. The purpose of this study is to evaluate the clinical features, laboratory data, and outcome of patients with JDM. Methods: We identified 21 patients (8 males and 13 females: average age 7.1±4.9 years) diagnosed as JDM at Yonsei Medical Center between March 1986 and August 2001 by retrospective chart review. The diagnosis of JDM was based on the published criteria proposed by Bohan and Peter in 1975. Results: The average time between the initial symptoms and the diagnosis of JDM was 4.0±7.5 months (range, 1~36 months) with the peak of onset in the summer months (June to august, 48%). The most common presenting feature was proximal muscle weakness followed by skin rash. Other symptoms were respiratory symptoms (33%) and calcinosis (10%). Laboratoy abnormalities included elevation of CPK (81%), AST (62%), LDH (43%) and antinuclear antibody (47%). Electromyograms were abnormal in 13 of 16 performed, showing characteristic myopathic abnormalities. Muscle biopsies revealed typical changes in 11 of 17 performed. All patients were treated with prednisolone (1~2 mg/kg/day) as part of their initial therapy, and 6 cases received intravenous high dose methylprednisolone (30 mg/kg/dose for 3 days). Methotrexate (5 cases), cyclosporine (5 cases), hydroxychloroquine (3 cases), and NSAIDs (2 cases) were given as a second drug, if required. Eleven cases had a monocyclic, 5 cases a chronic polycyclic, and 5 cases a chronic continuous course. One fulminant type case died of sepsis secondary to cellulitis on both axilla. Conclusion: The results of our review agree with other studies reported, but our study showed less occurrence of respiratory symptoms and calcinosis than other reports, and showed the peak incidence in the summer months. Given the fact that the number of our sample was small, future multicenter studies will be necessary.

Adaptive Nearest Neighbors를 활용한 판별분류방법

전명식,최인경,Jhun, Myoung-Shic,Choi, In-Kyung 한국통계학회 2009 응용통계연구 Vol.22 No.3

비모수적 판별분류방법으로 널리 사용되는 ${\kappa}$-Nearest Neighbors Classification(KNNC) 방법은 자료의 국소적 특징을 고려하지 않고 전체 자료에 대해 고정된 이웃의 개수 ${\kappa}$를 사용하여 개체를 분류하는 방법이다. 본 연구에서는 KNNC의 대안으로 자료의 국소적 특징을 고려하는 Adaptive Nearest Neighbors Classificaion(ANNC) 방법을 제안하였다. 제안된 방법의 특징을 규명하기 위하여 실제 자료에 대한 분석을 통하여 제안된 방법의 응용 가능성을 제시하였으며, 나아가 모의실험을 통하여 기존의 방법과의 효율성을 비교하였다. The ${\kappa}$-Nearest Neighbors Classification(KNNC) is a popular non-parametric classification method which assigns a fixed number ${\kappa}$ of neighbors to every observation without consideration of the local feature of the each observation. In this paper, we propose an Adaptive Nearest Neighbors Classification(ANNC) as an alternative to KNNC. The proposed ANNC method adapts the number of neighbors according to the local feature of the observation such as density of data. To verify characteristics of ANNC, we compare the number of misclassified observation with KNNC by Monte Carlo study and confirm the potential performance of ANNC method.

의약품 수용액의 염소 처리에 의한 돌연변이원성에 관한 연구

최인경 德成女子大學校 藥學硏究所 1997 藥學論文誌 Vol.8 No.1

In this paper, an investigation was performed to select the precursors of mutagenic by chlorination of aqueous solution of pharmaceuticals and to trace the change of the mutagenicity with time. When fructose and glucose was used as the precursor of chlorination, Ames mutagenicity was not detected. However, humic acid and tyrosine showed mutagenicity as reported in the literature. The mutagenicity in the chlorination procedure was maximum at the beginning of the reaction and decreased with time. Acetaminophen which has similar chemical structure as tyrosine showed mutagenicity at a concentration level of 1/100 of the extract from an aqueous reaction mixture of TOC:Cl=1:1, but aspirin, furosemide, reserpine, dexamethasone showed positive at levels of 1 to 1/40.

高英秀,崔仁敬 漢陽大學校 師範大學 1983 論文集 Vol.- No.3

The anti-oxidants contained in 17 commercial edible oils were analyzed using thin layer chromatography (TLC) and gas liquid chromatography(GLC). Out of 17 samples, 15 contained butylated hydroxy toluene (BHT) and 14 contained butylated hydroxy anisole(BHA). Tert-Butyl hydroquinone (TBHQ) was not found in any of the samples examined. Perilla oil and sesame seed oil which were produced by conventional compression method were also examined. These oils did not contain any synthetic antioxidants but contain natural antioxidant, tocopherol.

The objective of this study is to investigate the effects of Salicormia Herbacea L. especially on carbon tetrachloride induced hepatotoxicity. The Sprague Dawley Rates were administered the Salicornia Herbacea L. orally at 500 and 750㎎/㎏ for consecutive days, followed by an intraperitoneal administration of carbon tetrachloride at 0.4㎖/㎏ in corn oil. The elevated alanine aminotransferase(ALT) and aspartate aminotransferase (AST) activities, which had been induced by the administration of Salicornia Herbacea L. The liver vacuolization and lymphoid cell aggregation by carbon tetrachloride were clearly elevated by the Salicornia Herbacea L. as determined by histological examinations. All data from this study showed that the administration of Salicornia Herbacea L. prior to CCl_4 injection, resulted in the protection of rats from hepatotoxicity, suggesting that it could be used to develop new drug with protective effect against hepatotoxicity.
