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.

This study was to analyze characteristics based on tolerance and trophic guilds and to determine the level of total mercury in tissues of sentinel species, Zacco platypus at 3 sampling sites of the Mangyeong River in 2007. Total sampled fishes were 26 species and the most dominant species was Zacco temminckii (47%). Fish community analysis was resulted that eveness index and diversity index showed low value at S1. However, diversity index and richness index at other sites showed high. According to various guilds analysis, relative abundance of sensitive species was 70% and 42% at S1 and S2, respectively. While sensitive species were decreased (1%) and tolerant species were increased (60%) at S3. It was mainly carried to the impacts of wastewater treatment plants near the location. Relative abundance of insectivore species was decreased from up (S1) to midstream area (S3). In addition, chemical water quality, based on analyses of BOD, COD, TP, TN, EC, MPN and SS concentration showed similar trends. Qualitative Habitat Evaluation Index (QHEI) was averaged 164, judged as "good" habitat condition. Average concentrations of total [Hg] was 146.9 ${\mu}g$ $kg^{-1}$. In the muscles of total [Hg] was the highest, and then followed by kidney, vertebrae, liver, and gills. According to FDA standards (500 ${\mu}g$ $kg^{-1}$) of Korea, total [Hg] has not affected to the individual fish health.

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.

Following the previous reports (Part I : For Sea-Divers and Hwa-Jeon-Min; Part II : For male and female Buddhists) Authors have conducted another nutrition survey for the island inhabitants living in Sa Hoo Ri, Goon Oi Myun, Wan Do Goon, Jon Nam Province. The following results were obtained. 1. Cereals, green vegetables and fishes and shell-fishes were major food for the inhabitants, and the amounts of the intakes of these foods were 54%, 28.5%, 5.3% of total intake, respectively. The Calorie derived from carbohydrate occupied approximately 80% of total calorie intaken. 2. The calorie intakes of the inhibitant, were generally lower compared with the Korean Recommended Dietary Allowances. 3. Protein intake was generally good, but animal protein occupied only 19.4% of total protein intake. 4. Fat intake was very low and the calorie from fat occupied only 6.1% of total calorie intaken. 5. Vitamin A intake was low, and 99.4% of the total Vitamin A intaken consisted of carotene. 6. Vitamin $B_1\;and\;B_2$ intakes were low, especially Vitamin $B_2$ intake was very low.

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.
