Three-hundred samples of powdered infant formula milk and related products from four different manufacturers in 2010 were collected and surveyed their contaminations for aerobic bacteria, coliform, Enterobacter(Cronobacter) sakazakii, and food-borne pathogens. Fifteen samples of sterilized infant formula milk were all negative on these microorganisms. In all collected products of un sterilized infant formulas and follow-on infant formulas, aerobic bacteria were detected at 239 (83.9%) among 285 samples, and they all were found below $10^3$ cfu/g. Coliform bacteria were also detected at four among 285 samples. Salmonella spp. and Ent. sakazakii, weren't detected at the all samples. Bacillus cereus was detected at 24 (8.4%) among 285 samples. The level of B. cereus was below 100 cfu/g but it was suitable for the range of specification of B. cereus in infant formulas. Clostridium perjringens, Escherichia coli O157:H7, Staphylococcus aureus and Listeria monocytogenes weren't also detected. In consequence, it was suitable for total viable count, coliform and potential pathogen to the specification of infant formulas and related products.

This study was conducted to investigate the detoxification effect of extract from soy-sprout grown using high concentrated oxygen water extract (SE) against alcohol-induced hangover in male Sprague-Dawley (SD) rats. The rats were orally administered with different concentrations of SE beverage [26, 260 and 2,000 mg/kg body weight (b.w.)] and, after 30 min, with alcohol at a dose of 3 g/kg b.w. After 1 and 3 h of alcohol administration, blood was collected from the retro-orbital plexus, while after 5 h, blood was collected from the heart. In the 2,000 mg/kg b.w. SE group, the concentration of blood alcohol was significantly reduced after 1-5 h of alcohol loading as compared with that in the other groups. In addition, the blood acetaldehyde concentration was reduced by SE (2,000 mg/kg b.w.). These results suggest that SE beverage can alleviate alcohol hangover symptoms by stimulating the activities related to hepatic alcohol-metabolizing enzymes.

Previously we have reported that administration of Korean red ginseng water extract (KRG-WE) plays both preventive and therapeutic roles in testicular toxicity of guinea pigs exposed to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Further study was carried out to verify the beneficial role of Korean red ginseng in TCDD-induced testicular toxicity with different animal species by different route of administration. Korean red ginseng crude saponin (KRG-CS) was prepared by Diaion HP-20 adsorption chromatography. One hundred twenty rats (Sprauge Dawley, 200${\pm}$10 g) were divided into 6 groups. The normal control group (NC) received vehicle (i.p.) and saline (p.o.). Predetermined dosage of TCDD (40 $\mu\textrm{g}$/kg b.w., i.p.) was administered to single TCDD-treated (TT) and test (CS) groups. KRG-CS was admin-istered (p.o.) at daily doses of 5 (CS5), 10 (CS10),20 (CS2O) and/or 40 mg/kg b.w. (CS40) for 5 weeks, starting 1 week before the TCDD-exposure. Body weight gain, organ weights, and sperm quality were investigated. Decrease in body weight gain induced by TCDD was greatly attenuated by KRG-CS in a dose-dependent manner. Testicular weight, sperm head counts and ratio of sperm with progressive movement in TT group decreased significantly but those parameters were improved by the treatment of KRG-CS in a dose-dependent manner. This result led us to conclude that crude saponin might be the active ingredient of Korean red ginseng that attenuates the testicular toxicity induced by TCDD.

The main active components of Panax ginseng are ginsenosides. Ginsenoside Rb1 and Rg1 are accepted as marker substances for quality control worldwide. The analytical methods currently used to detect these two compounds unfairly penalize steamed and dried (red) P. ginseng preparations, because it has a lower content of those ginsenosides than white ginseng. To manufacture red ginseng products from fresh ginseng, the ginseng roots are exposed to high temperatures for many hours. This heating process converts the naturally occurring ginsenoside Rb1 and Rg1 into artifact ginsenosides such as ginsenoside Rg3, Rg5, Rh1, and Rh2, among others. This study highlights the absurdity of the current analytical practice by investigating the time-dependent changes in the crude saponin and the major natural and artifact ginsenosides contents during simmering. The results lead us to recommend (20S)- and (20R)-ginsenoside Rg3 as new reference materials to complement the current P. ginseng preparation reference materials ginsenoside Rb1 and Rg1. An attempt has also been made to establish validated qualitative and quantitative analytical procedures for these four compounds that meet International Conference of Harmonization (ICH) guidelines for specificity, linearity, range, accuracy, precision, detection limit, quantitation limit, robustness and system suitability. Based on these results, we suggest a validated analytical procedure which conforms to ICH guidelines and equally values the contents of ginsenosides in white and red ginseng preparations.

There is the temporal correlation of the video sequence between the motion vector of current block and the motion vector of the previous block. If we can obtain useful and enough information from the motion vector of the same coordinate block of the previous frame, the total number of search points used to find the motion vector of the current block may be reduced significantly. In this paper, we propose the block-matching motion estimation using an adaptive initial search point by the predicted motion information from the same block of the previous frame. And the first search point of the proposed algorithm is moved an initial point on the location of being possibility and the searching process after moving the first search point is processed according to the fast search pattern. Simulation results show that PSNR(Peak-to-Signal Noise Ratio) values are improved UP to the 1.05dB as depend on the image sequences and improved about 0.33~0.37dB on an average. Search times are reduced about 29~97% than the other fast search algorithms. Simulation results also show that the performance of the proposed scheme gives better subjective picture quality than the other fast search algorithms and is closer to that of the FS(Full Search) algorithm.

Objectives : 1. Clinical trial for the efficacy evaluation of Korean acupuncture techniques in treating frozen shoulder. 2. Development of the standard clinical guidelines of the acupuncture treatment for the frozen shoulder. 3. Development of the new clinical protocol for the acupuncture treatments. 4. Verification of the hypothesis that treating at both the remote and the nearby acupoints according to the meridian theory is more effective than treating at only the nearby acupoints. Methods : 1. Research designed as Single blind, Randomized, Sham acupuncture controlled clinical Trial. 2. Assignment of 86 patients to one of three groups treated at nearby acupoints(group A), remote & nearby acupoints(group B), and sham points(group C) respectively. 3. Trial conducted at KIOM CRC of Dunsan oriental medical hospital, Daejeon Univ. 4. Estimation of the recovery rate of the frozen shoulder in subjects aged over 40. 5. Efficacy evaluation using VAS, SPADI, ROM and Improvement rate. Results : 1. There was no significant difference in VAS among the three groups. 2. Pain related scores in SPADI of the group B were significantly lower than those of the group A. 3. There was no significant difference in disability related scores of SPADI among the three groups. 4. External rotation of upper arm in the group B was significantly improved in comparison with that in the group C. 5. Abduction of upper arm in group A was improved with weak statistical significance in comparison with that in the group C. Conclusion : Acupuncture at both the remote and the nearby acupoints according to the meridian theory is effective to improve external rotation of frozen shoulder, and acupuncture at the nearby acupoints is effective to improve adduction of frozen shoulder. However it is not clear that acupuncture treatment at both the remote and the nearby acupoints according to the meridian theory is more effective than treating at only the nearby acupoints in the treatment of frozen shoulder. Since our study was a short term trial, a long term trial for a more precise evaluation of acupuncture treatment for frozen shoulder will be needed in the future.

In the first step, birth weights and weights at 9 and 12 months were analysed and their variability were studied. Birth weight of kids had large within breed variation ranging from 0.50 to 1.60 kg. There were more than 100 kids with birth weights ranging from 1.2 to 1.6 kg. The birth weight of kids increased with the increase of kidding weight of dams. The weights of kids at 9 and 12 months also showed large within variation ranging from 5.0 to 18.0 kg and 16.0 to 19.0 kg respectively. In the second step, these existing large within breed variations were exploited selecting best animals for further mating. The birth weight of selected group($1.13{\pm}0.2kg$) was significantly(p<0.01) higher than the random group($0.93{\pm}0.05kg$). The weights in selected group for 3 and 6 months were $4.94{\pm}0.04$ and $8.40{\pm}0.05kg$ and that of random group was $3.99 {\pm}0.08$ and $7.07{\pm}0.11kg$ respectively and differences wee significant. Significantly higher average daily gains were noticed for selected group ($42.7{\pm}0.43g/day$) as against random group($33.3{\pm}0.81g/day$). From the results it may be concluded that selection and mating of best performing animals have some effect on the improvement of growth performance of kids which may be exploited for future planning and development in the field of goat production.

In vitro activities of 13 antibiotics were assessed against 85 Brucella abortus isolates from naturally infected cattle in the Republic of Korea during 1998-2006, using broth microdilution test. Tetracyclines showed the most excellent activity against B. abortus, displaying MIC values of 0.5 ${\mu}g/ml$ or below. In particular, minocycline showed the lowest $MIC_{50/90}$ values (0.125/0.125 ${\mu}g/ml$) in this study. Among four fluoroquinolones tested, ciprofloxacin ($MIC_{50/90}$, 0.5/1 ${\mu}g/ml$) and norfloxacin ($MIC_{50/90}$, 8/8 ${\mu}g/ml$) had the most and the least activities, respectively. Gentamicin ($MIC_{50/90}$, 1/1 ${\mu}g/ml$) was more effective than streptomycin, erythromycin, rifampin, and chloramphenicol ($MIC_{50/90}$, 2/2 ${\mu}g/ml$).

This study is designed to analyze the child's behaviour development and consider parent's expectation toward it. In the research of the aspect of child's behaviour development, first, this study will analyze the change and development a child shows according to his age, sex, and the community where he is brought up, and then, the relationship between child's behaviour development and parent's expectation toward it. (1) Child's Behaviour Development. a) According to Age. At the age of three ; In such behaviours as wiping nose, dressing, brushing teeth, putting on coat alone, going to toilet for B.M., going on errands, and playing contentedly alone, washing hands, greeting his elders, a child at the age of three to four shows a rapid development, and therefore it seems better to train a child in these behaviors age of three. At the age of four ; In such behaviors sharing cakes with friends, riding on a tricycle, a child shows great development, at the age of four to five, and therefore it seems better to train him in them at the age of four. At the age of five ; In such behaviors as combing hair, putting toys away in proper place, telephoning a child shows great development at the age of five to six, and therefore it seems better to train him in them at the age of five. b) According to sex and community. As a whole, there is little difference between sexes and the communities. It can be estimated from this that sex or the community has on the whole no great influence on the basic aspects of child's behavior development. (2) Parent's expectation. On the whole parent's expectation falls short of a child's development in behaviors ; especially, bathing himself, dressing, going to toilet for B.M, going to toilet to urinate, telephoning, etc. This tendency is consficuous in the case of three or four year old children. This results from parent's protecting in excess their children and reducing the opportunities to encourage the children's independence by delaying the babyhood. (3) The relationship between child's behaviour development and parent's expectation. a) On the whole, the behaviour of a child is at a higher level than parent's expectation. b) As a child grows from three years to six, his behaviour develops on the whole in accordance with the increase of parent's expectation. But the level of the former is lower than that of the latter. c) According to computing a coefficient of correlation is as follows. 3 years old ; .84 4 years old ; .90 5 years old ; .87 6 years old ; .89 It shows there is a high correlation between child's Behaviour and Parent's Expectation.
