본 연구는 2007년 만경강의 중 상류의 3개 지점을 선정하여 어류의 길드특성 및 조직별 수은 함량을 분석하였다. 어류의 종조성 분석에 따르면 7과 26종이 채집되었으며, 주요 우점종은 갈겨니(47%)로 수질오염에 쉽게 사라지는 민감종(Senstive species)이 우점하였다. 상류의 S1지점은 균등도 및 종 다양도가 낮게 나타났으나 그 밖의 2개의 지점들에서는 종다양도 및 풍부도가 높은 것으로 나타났다. 내성도 길드 분석에 의하면 S1과 S2 지점에서는 민감종의 비율이 각각 70%, 42%을 보였으나 반면 공단이나 도심지의 점오염원에 의해 영향을 받는 S3 지점은 민감종의 비율 감소(1%) 및 내성종의 비율(60%)이 증가하였다. 트로픽 길드 분석에서는 충식종의 비율이 S1에서 S3으로 갈수록 감소하였다. 이런 특성은 유기물질 (BOD, COD), 영양염류 (TN, TP), 전기전도도, 대장균수 및 부유물질에 근거한 이 화학적 수질 평가 결과와 일치하였다. 물리적서식지평가 (QHEI)는 3지점에서 모두 '양호'상태로 나타나 물리적 서식지가 양호한 상태일지라도 수질에 의해 어류의 종구성이 달라질 수 있음을 나타냈다. 어류의 조직 (tissue) 내의 총 수은 함량 분석에 따르면, 평균 농도는 149.6 ${\mu}g$ $kg^{-1}$로서 식약청의 기준(500 ${\mu}g$ $kg^{-1}$)에 따르면 어류 건강성에 영향을 줄만한 농도는 아닌 것으로 평가되었다. 각 조직별 수은 농축도는 근육에서 가장 높았고, 신장, 척추, 간, 아가미의 순으로 나타났다.

Rubia cordifolia L (Indian madder) contains red color purpurin (65-67%) and yellow color munjistin (10-12%) as well as nordamncanthal (9-10%). Purpurin is a traditional red dye. The purpose of this research is to increase the dyeability of silk and light fastness of dyed silk fabric. We dyed silk fabrics after pretreatment to remove the yellow component of madder using various solvents such as ethyl acetate, ethanol, methanol, chloroform, and acetone. The total K/S value was the highest in the case of chloroform and reflectance was the lowest at the red color region from 470nm to 530nm. Chloroform dissolved the yellow color of Rubia cordifolia; in addition, we found that the total K/S value increased and the ${\Delta}E$ value decreased by chloroform pretreatment for silk dyeing.

Crude extracts of thirty seaweeds collected in Korea were obtained using 50% ethanol, and total phenolic contents and antioxidant activities were compared. Two brown algae, Ecklonia cava (E. cava) and Sargassum siliquastrum (S. siliquastrum), showing high antioxidant activity based on 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and superoxide anion radical scavenging activity were further investigated for their inhibitory effects on tyrosinase activity. The E. cava extract had the highest total phenolic content among the seaweeds extracts. Total phenolic contents were strongly correlated with antioxidant activity in the thirty seaweed extracts ($R^2\;=\;0.9169$). The E. cava and S. siliquastrum extracts exhibited higher inhibition to tyrosinase activity than butylated hydroxytoluene (BHT) and epigallocatechin gallate (EGCG).

Objectives: This study was undertaken to analyze Staphylococcus aureus from cultivation environments for agricultural products and to confirm antibiotic resistance and enterotoxin genes for the isolated S. aureus. Methods: A total of 648 samples were collected from apple, peach, ginseng and balloon flower farms. S. aureus was isolated from soil, agricultural water, personal hygiene elements (hands, gloves and clothes) and work utensils (boxes). Results: S. aureus was detected in a total of 25 samples and 72 strains were isolated. The resistance rate of the isolated S. aureus strains was confirmed at 33.3%, with 24 resistant strains among the total of 72. Fourteen different patterns types were found, and three pattern types (NV, OX, VA) were confirmed most frequently. As result of the detection of enterotoxin gene type, four gene types (sea: 1, sed: 4, seg: all isolated S. aureus, sei: all isolated S. aureus) were analyzed among a total of nine types. Conclusions: This study demonstrates that personal hygiene techniques should be properly managed, such as washing and sterilization before or after work, because agricultural contamination by S. aureus frequently developed through improper management.

This study evaluated the development of osteolysis of Kudo total elbow arthroplasties according to the fixation with or without cement. Twenty-four elbows of nineteen patients of rheumatoid arthritis underwent total elbow arthroplasty from 1986 to 1993. The patients were followed for an average of 42 months ranging from 36 months to 59 months. In cemented humeri, 1 of 13 (7.7%) showed osteolysis. In the humeri of cementless fixation, 5 of II (45.5%) revealed osteolysis, representing higher rate compared to cement fixation (P<0.05). In the ulna, osteolysis was identified in none of 16 (0%) of cement fixation, which was significantly less than the incidence of osteolysis in cement less fixation (3 of 8,37.5%) (P<0.01). It was concluded that the cement fixation result in less osteolysis than the cementless fixation in Kudo type total elbow arthroplasty.

Separate protocols are commonly used to prepare plasmid DNA, chromosomal DNA, or total RNA from E. coli cells. Various methods for the rapid preparation of plasmid DNA have been developed previously, but the preparation of the chromosomal DNA and total RNA are usually laborious. We report here a simple, fast, reliable, and cost-effective method to extract total nucleic acids from E. coli by direct lysis of the cells with phenol. Five distinct and sharp bands, which correspond to chromosomal DNA, plasmid DNA, 23S rRNA, 16S rRNA, and a mixture of small RNA, were observed when analyzing the prepared total nucleic acids on a regular 1-2% agarose gel. The simple and high-quality preparation of the total nucleic acids in a singe tube allowed us to rapidly screen the recombinant plasmid, as well as to simultaneously monitor the change of the plasmid copy number and rRNA levels during the growth of E. coli in the liquid medium.

Job's tears (Coixlachryma-jobi L.) and Chungkukjang (soybean-fermented food) were abundant source of phenolic compounds. In this study, almond cookies were prepared with different concentration(5%, 10%, 15%), of Job's tears Chungkukjang powder. The total phenolic contents were measured by the Folin-Ciocalteu method, total flavonoids contents were measured, and antioxidant activities were evaluated by DPPH assay. Antioxidative activity was highly correlated with the total phenolic and total flavonoids contents of Job's tears Chungkukjang almond cookies (r=0.867, r=0.647). In addition, the quality characteristics of the Job's tears Chungkukjang almond cookies were estimated based on the bulk density and pH of the dough, spread factor, color, texture profile analysis, proximate composition, and sensory evaluations. The spread factor, hardness, a value and b value, total polyphenolic contents, and DPPH free radical scavenging activity of cookies significantly increased with increasing content of Job's tears Chungkukjang powder (p<0.01), whereas the L values of the cookies decreased with the increasing Job's tears Chungkukjang powder content (p<0.05). The acceptability scores for the 5-15% Job's tears Chungkukjang almond cookie groups were ranked higher than those of the other groups in appearance, texture, and overall preference. The results of this study were shown that Job's tears Chungkukjang powder was a good ingredient for increasing the consumer acceptability and the functionality of cookies.

In the patients of retracted massive rotator cuff tears, there are much of difficulty to functional recovery and pain relief. Nevertheless the development of treatment, there are still debates of the best treatments in the massive rotator cuff tears. Recenlty various of treatments are introduced; these are acromioplasty with debridement, biceps tenotomy, great tuberoplasty with biceps tenotomy, partial repair, mini-open rotator cuff repair, arthroscopic rotator cuff repair, soft tissue augmentation, tendon transfer, flap, hemiarthroplasty, and reverse total shoulder arthroplasty. That there is no difference of result for reverse total shoulder arthroplasty between patients who have massive rotator cuff tear without arthritis and patients who have cuff tear arthropathy. Reverse total shoulder arthroplasty is one of reliable and successful treatment options for massive rotator cuff tear. Especially it is more effective for patients who have a pseudoparalysis.

Persistent cloaca in a female newborn is one of the most complex and challenging anorectal malformation. The incidence is about 10% of all anorectal anomalies. Treatment of cloacal malformations has evolved during the past 40 years. However, it still remains one of the most difficult operations. In 1997, Pena reported a new procedure called "Total urogenital mobilization". We have repaired 3 cases of cloacal anomaly using "Total urogenital mobilization". The operations were performed between age 15 and 28 months. The length of the common channels was 2.5 - 3.0 cm. Two cases had double vaginas and one of them also had double uterus. The operation time was 4-5 hours and no major complications occurred. Functional and cosmetic results were satisfactory.
