Purpose : The majority of PCL deficient knees have some intact remnant PCL bundles. In these cases, the remnant PCL bundles were removed fur easy passage of graft(especially in bone-patellar tendon-bone graft). The purpose of study is to report the results of PCL reconstruction by posterior transseptal portal technique and by preserving the remnant posterior cruciate ligament bundles. Materials & Methods : From November 1993 to June 1999, 44 arthroscopic posterior cruciate ligament reconstructions have been performed by one surgeon. We studied 37 knees those were followed up over 1 year among them. The mean age($14\~56$ years) was 31.8 years. The average follow-up period was 17.8 months($12\~61$ months). The graft materials were 29 double-loop hamstring autografts, 4 double-loop hamstring allografts and 4 Achilles tendon-bone allograft. Results : There are significant improvement of the preoperative subjective symptoms. The last follow-up shows that the average Lysholm knee score was markedly improved from 59.8 pre-operation to 89.2 post-operation and the average KT 2000 side difference was decreased from 11.1mm pre-operation to 2.3 mm post-operation. Follow-up MRI showed that the graft was healed with remnant posterior cruciate ligament bundles as one ligament. Conclusion : The posterior trans-septal portal makes it possible to locate the exact tibial tunnel. The arthroscopic PCL reconstruction preserving the remnant of original PCL bundles seems to provide the good result.
Purpose: To evaluate the clinical stability and function after arthroscopic anterior cruciate ligament(ACL) reconstruction using fresh-frozen tibialis tendon allograft. Materials and Methods: Of the patients who underwent ACL reconstruction using tibialis tendon allograft from July 2002 to June 2003, thirty-one patients could be evaluated and the mean follow-up period was 19 months. Evaluations included were Lysholm knee score, 2000 International knee Documentation Committee (IKDC) subjective knee score, Lachman test, pivot shift test, KT-1000 arthrometer measurement and 2000 IKDC knee examination. Results: The mean Lysholm score was 88. Twenty-eight patients (90.3%) were good or exellent for the measured parameters. Twenty-seven patients(87.1%) was over 70 in IKDC subjective knee score. Thirty patients (96.8%) had 1+ firm end or negative Lachman test. 27 patients (87.1%) had a negative pivot shift. Thirty patients (96.8%) had less than 5mm difference of maximal manual difference by KT-1000 arthrometer. Twenty -nine patients (93.5%) were nearly normal or normal grade by 2000 IKDC knee examination. Complications were 1 case of failure and 1 case of infection. Conclusion: ACL reconstruction with the double-stranded fresh-frozen tibialis tendon allograft resulted in a reliable and predictable outcome after short-term follow-up.
Purpose: This study reported the outcomes following the use of bioabsorbable knotless anchor in patients with anterior instability of shoulder. Methods: We studied fifteen cases with traumatic anterior shoulder instability underwent arthroscopic Bankart repair with bioabsorbable knotless suture anchor between January 2003 and June 2003. Among fifteen patients, fourteen were male and one was female, with a mean patient age of 24 years (range 16-42). The mean follow-up was 14 months (range 12-18 months). We compared with operation time of twenty cases of arthroscopic Bankart repair by the suture anchor technique between January 2002 and October 2002. Results: Neither recurrent dislocation nor subluxation was happened in postoperative follow-up. Mean score for functional evaluation by Rowe et al. was 89.4 and that for patient subjective satisfaction was 87,5. At last follow-up period, average shoulder range of motion for flexion and external rotation was 171$^{\circ}$ and 54$^{\circ}$ respectively. All patients were satisfied except three who had an apprehension at the follow up. During Bankart repair, it took an average of 25.5 minutes for one knot with the use of suture anchor technique whereas an average of 16.5 minutes for one knot with the use of bioabsorbable knotless anchor. Significantly, we saved operation time with the use of bioabsorbable knotless anchor (P<0.05).Conclusion: Repairing the Bankart lesion with the use of knotless anchor technique has the advantage of obtaining good capsular tensioning and saving operation time. And it is considered to be very successful in treating shoulder instability without recurrent dislocation or subluxation.
Due to the growth of internet data and the rapid development of internet technology, "big data" analysis is actively conducted to analyze enormous data for various purposes. Especially in recent years, a number of studies have been performed on the applications of text mining techniques in order to overcome the limitations of existing structured data analysis. Various studies on sentiment analysis, the part of text mining techniques, are actively studied to score opinions based on the distribution of polarity of words in documents. Usually, the sentiment analysis uses sentiment dictionary contains positivity and negativity of vocabularies. As a part of such studies, this study tries to construct sentiment dictionary which is customized to specific data domain. Using a common sentiment dictionary for sentiment analysis without considering data domain characteristic cannot reflect contextual expression only used in the specific data domain. So, we can expect using a modified sentiment dictionary customized to data domain can lead the improvement of sentiment analysis efficiency. Therefore, this study aims to suggest a way to construct customized dictionary to reflect characteristics of data domain. Especially, in this study, movie review data are divided by genre and construct genre-customized dictionaries. The performance of customized dictionary in sentiment analysis is compared with a common sentiment dictionary. In this study, IMDb data are chosen as the subject of analysis, and movie reviews are categorized by genre. Six genres in IMDb, 'action', 'animation', 'comedy', 'drama', 'horror', and 'sci-fi' are selected. Five highest ranking movies and five lowest ranking movies per genre are selected as training data set and two years' movie data from 2012 September 2012 to June 2014 are collected as test data set. Using SO-PMI (Semantic Orientation from Point-wise Mutual Information) technique, we build customized sentiment dictionary per genre and compare prediction accuracy on review rating. As a result of the analysis, the prediction using customized dictionaries improves prediction accuracy. The performance improvement is 2.82% in overall and is statistical significant. Especially, the customized dictionary on 'sci-fi' leads the highest accuracy improvement among six genres. Even though this study shows the usefulness of customized dictionaries in sentiment analysis, further studies are required to generalize the results. In this study, we only consider adjectives as additional terms in customized sentiment dictionary. Other part of text such as verb and adverb can be considered to improve sentiment analysis performance. Also, we need to apply customized sentiment dictionary to other domain such as product reviews.

To assess the food intake and diet quality of middle school students who live in Kangneung area, a dietary survey using 3-day food record was conducted with 226 subjects. Seventy five percent of total food intake was in the form of plant foods and the rest in the form of animal food. Diet qualify was assessed by food group pattern, dietary diversity score (DDS), and dietary variety score (DVS). When counting the major food groups consumed, 53% of subjects had a DDS of 3 and 35% of subjects had a DDS of 4. When investigating the consumption pattern of the major five food groups, only 10.2% of subjects consumed foods from all five groups. The groups most frequently missed were dairy products (73.0%) and fruits (71.7%). On average, subjects habitually consumed 22.6 different foods daily, with the mean score of diet variety for males (22.1) being significantly lower than for females (22.9). Correlation coefficients between nutrient adequacy ratio (NAR) and DVS ranged from r=0.40 for vitamin B$_1$to r=0.61 for phosphorus. NAR also improved as the number of foods or food groups consumed increased (p<0.001). Associations between the NAR and high level of DVS was more positive than those between the NAR with DDS. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. Therefore, to lead them to have nutritionally balanced diet, educating students and their parents on nutrients and suggesting guidelines for a desirable diet is considered to be essential so that they can intake from all of major food groups and have various foods in their diet.

Our preliminary study showed that genistein and daidzein improved blood glucose level in type 2 diabetic mice by enhancing the glucose and lipid metabolism. The objective of this study was to evaluate whether genistein and daidzein are associated with alterations in antioxidant defense mechanism of type 2 diabetic mice. Male C57BL/KsJ-db/db (db/db) mice and age-matched non-diabetic littermates (db/+) were used in this study. The db/db mice were divided into control, genistein (0.02%, w/w) and daidzein (0.02%, w/w) groups. The relative weights of liver, epididymal adipose tissue and perirenal adipose tissue were significantly higher in the db/db group than in the db/+ group, whereas heart weight was lower. The genistein and daidzein supplement did not affect the organ weights in db/db mice. The blood glucose level was positively correlated with superoxide dismutase (SOD, r=0.380, p<0.05) and catalase (CAT, r=0.345, p<0.05) activities and negatively correlated with glutathione peroxidase (GSH Px, r= 0.404, p<0.05) activity in erythrocyte. Therefore, the erythrocyte SOD and CAT activities were significantly elevated in the db/db group compared to the db/+ group and the GSH-Px activity was lowered. However, the supplementation of genistein and daidzein reversed erythrocyte CAT and GSH-Px activities in type 2 diabetic mice. In this current study, the SOD activities in liver, kidney and heart were significantly not different between the groups. The CAT and GSH-Px activities in liver and GSH-Px activity in kidney were significantly higher in the db/db group than in the db/+ group, while the CAT activity in kidney, CAT and GSH-Px activities in heart were lowered. The supplementation of genistein and daidzein significantly attenuated the changes of CAT and/or GSH-Px activities in liver and heart. The supplementation of genistein and daidzein elevated GSH levels in kidney and heart compared to the db/db control group. The lipid peroxide levels in liver, kidney and heart were significantly lowered in the genistein and daidzein supplemented groups compared to the db/db control group. These results suggest that genistein and daidzein might be beneficial for the prevention of type 2 diabetic complication via suppressing changes of antioxidant enzymes activities with simultaneous reduction of lipid peroxidation.

This study investigated the effects of green tea on the disorders of lipid metabolism, oxidative system and hepatic functions induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), using adult male rats (SD) for 3 weeks. These 36 animals were divided into four groups. TCDD ($50{\mu}g/kg$ BW) was intraperitoneally injected at the beginning of experiment. Green tea powder was added 1% or 3% levels in basal diets respectively. Relative weights of thymus were decreased about one-third of control group, but those of liver, brain and testis were significantly increased in rats treated TCDD. Neutrophill% and lymphocyte% by TCDD treatment was improved by green tea diets. In liver functional enzyme, elevation of glutamic oxaloacetic transaminase (GOT) and alkaline phosphatase (ALP) activities due to TCDD treatment was lowered by green tea diets. The concentrations of serum and liver lipids were significantly increased by TCDD treatment, however, those of serum and liver triglyceride tended to decrease by green tea diets. Fecal lipid excretion was increased in rats fed green tea diets. Especially, fecal total cholesterol level was significantly elevated by 3% green tea diets. The activities of superoxide dismutase (SOD) were increased in rats fed 3% green tea diets. Increment of benzphetamine N-demethylase (BPND) activity by TCDD treatment was declined by 1% green tea diets. These results indicate that green tea can exert improving effects on liver lipid accumulation and unfavorable hepatic functions, and elevate antioxidation.

The objectives of this study were to determine antioxidant activities and antioxidnat compounds of 13 imported and 4 domestic red wines and to investigate relationships between antioxidant activities and antioxidant compounds in the selected red wines. The concentrations of total polyphenolics and anthocyanins in the samples were investigated by spectrophotometric methods. ABTS (2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid) and DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity, and reducing power have been used to compare the relative antioxidant activities of the selected red wines. In this study, total polyphenolic contents of the red wines were ranged from 250 to 2,298 mg gallic acid equivalents/L and the anthocyanin contents were ranged from 11 to 349 mg cyanidin-3-glucoside equivalents/L, respectively. As expected, all the red wines exhibited excellent antioxidnat activities (ABTS and DPPH radical scavenging and reducing power) except three domestic red wines. The correlation coefficient between total polyphenolic content and their antioxidant activities, namely ABTS radical scavenging activity, DPPH radical scavenging activity and reducing power, were 0.9784, 0.9905 and 0.8580, respectively. No correlation was observed between total anthocyanin content and their antioxidant activities.

This study was designed to investigate the effect of flower of Pueraria lobata on liped peroxidation and activities of alcohol metabolic enzymes in alcohol-treated rats. Male Spra gue-Dawley rats were given 25% ethanol (Alcohol), 25% ethanol and 5 mg tectorigenin/kg B.W.(Alc.-Tec), 25% ethanol and 5mg kaikasaponin III/kg B.W. (Alc-Kai). The contents of serum total lipid, triglyceride and phospholipid were increased by ethanol treatment and were lower in the Alc.-Tec and Alc.-Kai group than in the Alcohol group. Decreased serum HDL-cholesterol by alcohol treatment was recovered by tectorigenin and kaikasaponin III. Microsomal cytochrome P-450, aniline hydroxylase and aminopyrine N-demethylase activities were increased by ethanol and were lower in the Alc. Tec and Alc.-Kai group than in the Alcohol group. Activity of hepatic alcohol dehydrogenase was increased by ethanol and was higher in the Alc.-Tec and Alc.-Kai group than in the Alcohol group. Microsomal ethanol oxidizing system activity was higher in Alc.-Tec group than in the other group. No significant difference was found in catalase activity among treatment groups. These data indicate that tectorigenin and kaikasaponin III were effected alcohol metabolic enzyme system and the liver damage associated with chronic ethanol consumption.

The base for preparing oyster hydrolysate-added yogurt was consisted of whole milk (1,000 mL), skim milk (44.05 to 42.05 g), enzymatic oyster hydrolysates powder (OHP, 0 to 2.0 g) and pectin. The yogurt base was fermented with 7 kinds of starter cultures (3% based on yogurt volume), such as Lactobacillus acidophilus, lactobacillus bulgaricus, lactobacillus casei, Lactobacillus fermentum, Lactobacillus pentosus, Streptcoccus thermophilus and the mixed starters (L. bulgaricus and S. thermophilus) at optimal temperature. Processing condition and quality characteristics of the yogurt were evaluated by analyzing pH, titratable acidity, viscosity, viable cell count, functional properties and sensory evaluation. The results suggested that the optimal conditions for preparing the good quality yogurt revealed the mixed starters (L. bulgaricus and S. thermophilus) for starter culture, 1.0 g of 3 kDa hydrolysate for amount, and 5.5 hrs for fermentation time. The good quality yogurt showed 4.31 for pH, 1.07% for titratable acidity, 469 cps for viscosity and $4.9{\times}10^8\;CFU/mL$ for viable cell count. The hydrolysate-added yogurt was 2 times higher in ACE inhibitory and antioxidant activities than commercial yogurt, and kept good quality during storage of 15 days at $5^{\circ}C$.
