      • 청정 지역 강우의 분석 : 1997-1998년 한라산 1100 고지와 제주시 강우의 특성 Characteristics of Rainwater at 1100 Site of Mt. Halla and Cheju City in 1997-1998

        강창희,김원형,홍상범,이기호,홍민선,심상규 濟州大學校 基礎科學硏究所 2000 基礎科學硏究 Vol.13 No.1

        The rainwater samples were collected from the 1100 Site of hlt. Halla and Cheju city during the period of March in 1997 to August in 1998. and the major soluble ions were analyzed. The confidence of analytical data was confirmed by using the comparison methods such as ion-balance, electric conductivity and acid fraction. all of which correlation coefficients were above 0.94. The ionic strengths lower than 10^(-4)M, the basis for the pure rainwater, were found in 47% and 38% at 1100 Site and Cheju city, respectively. The precipitations in Cheju city were more influenced by the oceanic effect than those in 1100 Site. The acidity contribution was mainly by SO_(4)^(2-) and NO_(3)^(-) in both areas. and the organic acids have contributed to the acidity with only 5-7%. The neutralization factors by NH_(3) were about 46% at both 1100 site and Cheju city, whereas those by CaCO_(3) were 11% and 15% at 1100 site and Cheju city respectively, and the free acidity were both about 35% in average. From the MSA analysis. it was found that the air in Cheju island has been influenced by the pollution from the other areas. The sources of the rainwater components in 1100 Site and Cheju city were also studied with a factor analyzing way and the most probable factors were found to be anthropogenic, oceanic, and soil-sourced. The results of multiple regression analysis have shown that SO_(4)^(??) was dissolved mostly in the form of H_(2)SO_(4), CaSO_(4) and (NH_(4))_(2)SO_(4). and NO_(3)^(-) was in the form of HNO_(3), Ca(NO_(3))_(2) and NH_(4)NO_(3).

        In vitro Antioxidative Activities and Phenolic Composition of Hot Water Extract from Different Parts of Cudrania tricuspidata

        Chang-Ho Jeong,Gwi Nam Choi,Ji Hye Kim,Ji Hyun Kwak,Ho Jin Heo,Ki-Hwan Shim,Bok-Rai Cho,Young-Il Bae,Jine-Shang Choi 한국식품영양과학회 2009 Preventive Nutrition and Food Science Vol.14 No.4

        We evaluated total phenolics and antioxidative activities of water extracts from different parts of Cudrania tricuspidata (specifically, the leaves, stems, roots, and fruits). The antioxidative activities of these samples were determined using five methods, including 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid (ABTS) radical scavenging, reducing power, ferric reducing ability of plasma (FRAP), and β-carotene/linoleic acid system. The water extract of leaves exhibited the higher DPPH, ABTS radical scavenging activities, reducing power, and FRAP than water extract of stem, roots, and fruits. Inhibition values on linoleic oxidation of water extracts from leaves, stems, roots, and fruits were calculated as 45.98%, 33.03%, 39.73%, and 25.48% at 10 ㎎/mL, respectively. The water extract of C. tricuspidata leaves had the highest amount of toal phenolics (73.60±0.28 ㎎/g). High-performance liquid chromatography (HPLC) analysis showed that quercetin is the predominant phenolic compound in water extract of leaves. Thus, our study verified that the water extract of leaves has strong antioxidant activities which are correlated with its high level of phenolic compounds, particularly quercetin. This water extract of C. tricuspidata leaves can be used as an effective and safe source of antioxidants.

        김명호(Myung-Ho Kim),유문집(Moon-Jib Yoo),서중배(Joong-Bae Seo),박희곤(Hee-Gon Park),심상호(Shang-Ho Shim) 대한정형외과학회 2005 대한정형외과학회지 Vol.40 No.6

        목적: 자기 공명 영상을 이용하여 측정한 슬개골의 두께를 분석하여 우리 나라 성인의 슬개골 두께에 대한 기초적인 자료를 얻는 것과 동시에, 슬관절 전치환술시 슬개골 치환물 선택에 도움이 될 자료로 제시하기 위한 목적으로 본 연구를 시행하였다. 대상 및 방법: 2002년 10월부터 2004년 6월까지 시행한 20세에서 39세 사이(평균 29세)의 성인 남녀 165예의 슬관절 자기 공명 영상을 이용하였다. 슬개골의 골절 또는 각종 변형이 있는 경우는 제외하였으며, 대상에 포함된 슬관절은, 반월상 연골 손상이 54예, 십자 인대 손상이 53예, 슬부 좌상이 24예, 정상 슬관절 17예, 기타 17예 등이었다. 계측 방법은 슬부 자기 공명 영상의 축상면 영상과 시상면 영상에서 슬개골의 전방 피질골에서 관절면의 연골까지 가장 두꺼운 부분의 두께를 0.1 ㎜ 단위로 측정하여 평균치를 구하였으며, 남녀간의 차이 및 체중과 신장에 대한 연관성도 분석하였다. 결과: 자기 공명 영상으로 측정한 슬개골 두께의 평균은 축상면 영상에서 남자는 23.8 (SD 1.4) ㎜, 여자에서 21.7 (SD 1.4) ㎜이었다. 축상면 영상에서 측정한 것과 시상면 영상에서 측정한 수치의 차이는 없었으며, 남성의 슬개골 두께가 여성보다 의미 있게 두꺼웠으며(p 〈0.01), 성인의 신장이 클수록, 체중이 무거울수록 슬개골 두께도 두꺼운 것으로 분석되었다(p〈0.01). 결론: 한국인의 평균 슬개골 두께는 남자가 23.8 ㎜, 여자가 21.7 ㎜로서, 여자보다는 남자가 두꺼웠고, 신장이 클수록, 몸무게가 무거울수록 슬개골이 더 두꺼웠다. Purpose: To provide information on the thickness of the patella in Korean adults and to provide a standard for the selection of a proper patella implant in total knee arthroplasty. Materials and Methods: From October 2002 to June 2004, the patellar thickness was measured by MRI in 165 knees. The mean age of the patients was 29 years (20-39 years). Patients with either patellar fractures or deformities were excluded. Of the knees included in this study, 54 knees had meniscal injuries, 53 had cruciate ligament injuries, 24 had knee contusions, and 17 had other disorders. The remaining 17 knees were normal. The measurements were taken in the axial and sagittal images of the MRI scans. The maximum distance in millimeter between the anterior cortex of the patella and the surface of the articular cartilage was measured to the first decimal place. The relationship between the patellar thickness and gender, weight and height was also analyzed. Results: The average patellar thickness on the axial image was 23.8 (SD 1.4) ㎜ in males and 21.7 (SO 1.4) ㎜ in females. The measurement estimated in the axial image was not significantly different from that in the sagittal image. The patellar thickness in males was significantly thicker than in females (p<0.01). There was a significant correlation between the patellar thickness and both the body weight and height (p<0.01). Conclusion: The average patellar thickness in Korean adults was 23.8 ㎜ in males and 21.7 ㎜ in females. The patella was thicker in males than in females. Moreover, the patellar thickness was proportional to the height and weight of each individual.

        동결건조 한 마늘 분말의 일반성분과 밀가루 중량 100%를 기준하여 0.5, 1.0, 2.0 및 4.0% 첨가하여 제조한 국수의 품질특성에 관하여 조사하였다. 동결건조 마늘의 일반성분은 일반성분 중 수분 4.72±0.14%, 조단백질 19.46±0.28%, 조지방 1.21±0.10%, 가용성 무질소물 68.45±2.06%, 조섬유 2.38±0.05% 및 회분 3.78±0.06%이었다. 동결건조 한 마늘분말을 첨가하여 제조한 국수의 중량, 부피 및 함수율은 대조구와 비교하여 분말의 첨가량이 증가함에 따라 감소하였으나, 국물의 탁도는 증가하였다. 조리 전 반죽의 색도는 동결건조 마늘분말을 첨가하였을 때 L, a 및 b값 모두 증가하였으며, 조리한 생면의 색도 중 L값은 감소하였으나, a값과 b값은 증가하였다. 동결건조 한 마늘 분말을 첨가하여 조리한 국수의 조직감은 밀가루만 첨가하여 제조한 대조구에 비하여 경도, 부착성, 탄력성, 검성, 씹힘성 및 응집성이 감소하는 경향을 보였다. 관능검사 결과 동결건조 마늘분말 0.5% 첨가구에서 대조구와 비교하여 유의적인 차이를 나타내지 않았다. This study investigated proximate compositions and quality characteristics of wet noodles with the addition of freeze dried garlic powders prepared at 0.5, 1.0, 2.0, and 4.0% based on flour source, respectively. The moisture, crude protein, crude fat, nitrogen free extract, crude fiber, and crude ash of the freeze dried garlic powder were 4.72±0.14%, 19.46±0.28%, 1.21±0.10%, 68.45±2.06%, 2.38±0.05%, and 3.78±0.06%, respectively. The cooked weight, volume, water absorption of cooked noodles were decreased, but the turbidity of soup was increased with the addition of garlic powder. Increased of L (lightness), a (redness) and b (yellowness) values were caused as the amount of garlic powder increased in dough. Decrease of L value and increase of a and b value were shown with the increase of garlic powder in cooked noodle. The cooked noodles with garlic powder were significantly lower in hardness, adhesiveness, springiness chewiness, gumminess and cohesiveness than those of 100% wheat noodle. Sensory evaluation indicated that cooked noodles with 0.5% garlic powder was not significantly different from the control.

        질경이 추출물의 DPPH 라디칼 소거효과 및 항균활성

        정창호(Chang-Ho Jeong),배영일(Young-Il Bae),심기환(Ki-Hwan Shim),최진상(Jine-Shang Choi) 한국식품영양과학회 2004 한국식품영양과학회지 Vol.33 No.10

        질경이를 새로운 기능성 식품소재로 활용하기 위한 일환으로 차전초의 메탄올 추출물을 각종 용매를 이용하여 계통ㆍ분획한 후 DPPH 라디칼 소거효과, 환원력, 아질산염 소거효과 및 항균활성에 대하여 조사하였다. DPPH 라디칼 소거효과는 분획물 중 에틸아세테이트와 부탄올 분획물(400㎍/5 mL)에서 60% 이상 높은 라디칼 소거율과 금속에 대한 강한 환원력을 나타낸 반면, 물, 클로로포름 및 헥산 분획물은 낮은 소거효과를 나타내었다. 질경이의 각 분획물을 농도별로 첨가한 아질산염 소거효과는 에틸아세테이트와 부탄올 분획물 500 ㎍ 첨가시 70~80% 이상 높은 아질산염 소거 효과를 나타내었다. 항균활성은 에틸아세테이트, 클로로포름 및 부탄올 분획물 순으로 높게 나타났으며, 에틸아세테이트 분획물의 경우 Staphylococcus aureus, Bacillus cereus 및 Vibrio parahaemolyticus 등의 그람양성 및 음성균 모두 강한 항균효과를 나타내었다. To develop the functional food, methanol extracts of dried plantain (Plantago asiatica L.) was fractionated in hexane, chloroform, ethyl acetate, butanol and aqueous fraction. DPPH radical scavenging effect, reducing power, nitrite scavenging effect and antimicrobial activities of these fractions were investigated. Ethyl acetate fraction among these fractions showed the highest effect of all experiments. Ethyl acetate fraction showed about 60% scavenging effect on the DPPH radicals at 400 ㎍/5 mL. Nitrite scavenging effect of ethyl acetate and butanol fraction was more than 70~80% at concentration above of 500 ㎍. Among various solvent fractions from methanol extracts of plantain, ethyl acetate fraction showed the highest inhibitory effect on the microorganism such as Staphylococcus aureus, Bacillus cereus and Vibrio parahaemolyticus at 5 mg/disc.
