In this paper, we proposed a verification of speaker change utilizing the KL distance based on GMM-UBM to improve the performance of conventional BIC based Speaker Change Detection(SCD). We have verified Conventional BIC-based SCD using KL-distance based SCD which is robust against difference of information volume than BIC-based SCD. And we have applied GMM-UBM to compensate asymmetric information volume. Conventional BIC-based SCD was composed of two steps. Step 1, to detect the Speaker Change Candidate Point(SCCP). SCCP is positive local maximum point of dissimilarity d. Step 2, to determine the Speaker Change Point(SCP). If ${\Delta}BIC$ of SCCP is positive, it decides to SCP. We examined verification of SCP using GMM-UBM based KL distance D. If the value of D on each SCP is higher than threshold, we accepted that point to the final SCP. In the experimental condition MDR(Missed Detection Rate) is 0, FAR(False Alarm Rate) when the threshold value of 0.028 has been improved to 60.7%.

This study is carried out to investigate the analysis of nutrition and antioxidants of soybean Chungkukjang powder (SCP), Yak-Kong Chungkukjang powder (YCP) and Yak-Kong Chungkukjang powder added black foods (YCBP) for the management of Alzheimer's disease. The water content of YCBP was higher than that of SCP and YCP. The soluble and crude protein contents of YCP were the highest among three Chungkukjang powders. In SCP, YCP and YCBP, the ratios of unsaturated and saturated fatty acids were 5.17, 5.76, and 5.78, respectively. The mineral content of SCP was higher than that of YCP and YCBP. Antioxidants analysis showed that the content of diadzein was the highest in YCP and genistein, and anthocyanin contents were higher than the others in YCBP. In conclusion, YCP and YCBP had higher contents than SCP in soluble and crude proteins, and unsaturated fatty acids, which are needed for composition and function of the brain tissue. Also, it was found that the contents of diadzein, genistein and anthocyanin with outstanding antioxidative ability were high. Thus, this study suggests that Chungkukjang powder, which is made with Yak-Kong, black sesame, black rice and sea tangle, can be utilized for in vivo experiment for the control of oxidative stress, reported as cause and therapy for Alzheimer's Disease.

Adsorption performance of sulfonamide antibiotic compounds such as sulfadimethoxine(SDM), sulfachloropyridazine(SCP), sulfamethazine(SMT), sulfathiazole(STZ) and sulfamethoxazole(SMX) on granular activated carbon(GAC) was evaluated in this study. The coal-based activated carbon was found to be more effective than other carbons in adsorption of sulfonamide antibiotic compounds. The wood-based activated carbon was less effective than coconut- and coal-based carbon in adsorption nevertheless having larger pore volume and specific surface area than others carbons. The maximum adsorption capacities(X/M) of coal-based activated carbon for the five sulfonamide species was 1.3$\sim$1.5 and 1.8$\sim$2.1 times larger than coconut- and wood-based activated carbon, respectively. Carbon usage rates (CUR) of coal-, coconut- and wood-based activated carbons for SCP were 3.55 g/day, 4.29 g/day and 6.47 g/day, respectively. Similar results were obtained in the adsorption of the rest four sulfonamide species. It is concluded that coal-based activated carbon could removed the sulfonamide antibiotic compounds better than other material-based activated carbons.

The enhancement effects of sea mustard extract (SME), starfish collagen peptide (SCP) and a mixture of the two (MIX) on skin activity were evaluated to investigate the possibility of using marine-derived extracts as cosmetic additives. The anti-inflammatory activity, whitening activity and skin elasticity activity of the extracts were analyzed to evaluate their skin-activating effects. Inhibiting the generation of nitric oxide (NO) and the tyrosinase and elastase inhibitory activities were assessed as the bio-markers for evaluating skin activity. SME, SCP and MIX did not show cytotoxicity within the concentration range of 1.0-50 ㎍/mL. In addition, SME, SCP and MIX all increased NO production and the tyrosinase and elastase inhibitory activities in a concentration-dependent manner. The activity of MIX was significantly increased compared to that with using SME or SCP alone. Taken together, when natural extracts are applied as cosmetic additives, the results demonstrate that using a mixture of SME and SCP may have a greater synergistic effect than that when using only a single extract. Therefore, this study contributes to the knowledge about the kinds and composition of several natural extracts when they are used as cosmetic additives.

Variations of agronomic traits were evaluated on the progenies of regenerated rice plants of different callus origin and subculture period. From eighty-eight percent to ninety percents of ovary culture-derived plants (OCP) and anther culture-derived plants (ACP) were not segregated within the lines in major agronomic characters. Compare to ACP and OCP lines, the seed culture derived lines (SCP) showed more segregation (17％) in major agronomic traits among the lines. The most frequent segregating traits were grain fertility (6.1％) in ACP, leaf color (4.2％) in OCP and grain fertility (4.9％) and leaf color (4.9％) in SCP lines. The SCP line showed more variation in culm length, panicle length and heading date than those of OCP and ACP lines. The variation of agronomic traits in SCP lines was tended to increase with prolonged subculture. Culm and panicle length were shorter than those of original cultivar in all three types of tissue culture-derived lines (OCP, ACP and SCP).

Objective : This study investigated the effect of intensive weight shift training (IWST) on the ability to balance in a sitting posture of children with spastic cerebral palsy (SCP). Methods : One child with spastic diplegia participated in this study for a total of 8 weeks using the ABA experimental design. For the pre-intervention period (A1), general physical therapy (GPT) for children with SCP was performed. The intervention period (B1 and B2), GPT and IWST were conducted for children with SCP, and GPT was conducted again for the post-intervention period (A'1 and A'2). Trunk control capacity was measured using the Korean Trunk Control Measurement Scale (TCMS-K) and Biorescue (RM Ingenierie, France). Results : All TCMS-K variables increased from A1 to B2, and decreased from B2 to A'2. The total area with limit of stability (LOS) increased from A1 to B2, and decreased from B2 to A'2. The ratio of the left/right (Lt/Rt) and anterior/posterior (Ant/Post) LOS area was closer to 1, meaning symmetry, in B2 than in A1. The ratio of the Lt/Rt LOS area decreased further from 1 in A'2 than in B2. The ratio of the Ant/Post LOS area was closer to 1 in A'2 than in B2. Conclusion : IWST had a positive effect on the improvement of balance in the sitting posture of a child with SCP. The results suggest that IWST might help to improve the balance abilities of children with SCP for independent sitting, postural control, and activities of daily living.

An application frequency of vertical drainage method is increasing as an effective consolidation acceleration method. PBD method is most frequently used as a consolidation acceleration method in vertical drainage methods. PBD is economical and easy to operate but has some problems those are an environmental pollution and a decrease of a discharge capacity caused by bending of drainage materials when it is used in great depth. SCP method was frequently used because it's discharge capacity was good but now it is rarely used because of an increase of the material price because of an order imbalance. As the way to solve these problems, GCP method has been to the fore. For analyzing the effect of GCP method on the discharge capacity, three types of composite discharge capacity tests are done by using GCP, SCP and PBD respectively with the circle case, ${\phi}38{\times}h70cm$. On the contrary to this, GCP shows the worst discharge capacity for a decrease of the void ratio and the clogging phenomenon caused by increasing load. Also to figure out the clogging range of GCP, the clogging of GCP is checked in each load stage with a large case($1.0m{\times}0.5m{\times}1.1m$) which has clear acrylic front face. The diameter of GCP was 35cm and a clogging phenomenon occurred in 10% approximately. The result shows that the discharge capacity of GCP was given the lowest value for a decrease of the void ratio and the clogging phenomenon causing by increasing load. And the clogging phenomenon mostly occurred within 10% of GCP's diameter range.

Laying hens are known to be able to 'bio-accumulate' the health-promoting ingredients of their diet into eggs. The purpose of this study was to characterize lignan-rich eggs as functional food fed with Schisandra fruit by-product (SCP). Experimental diets were formulated using yellow corn, rice bran, soybean meal, fish meal, meat bone meal, poultry meal, vitamin premix, mineral premix, CaCO₃, and supplemented Schisandra chinensis by-product. This experiment conducted a completely randomized design with 5 treatments for 5 laying hens. Levels of SCP were fed control diet or each formulated diet containing 1%, 3%, 5% and 7% SCP powder. The weight of eggs and the lignan content in white and yolk of egg were investigated every 7 days. Egg production and egg weight were not affected by diet at less than 5% SCP in the diet, but were significantly reduced when the diet was supplemented with a high concentration of 7% SCP after 3 weeks. Yolks and white in eggs were analyzed by using a high performance liquid chromatography (HPLC) to determine the lignans profile. Higher dietary SCP supplementation significantly increased gomisin N and schisandrin C in Acetonitrile (p<0.05). Gomisin N in egg white increased in a concentration-dependent manner, but shisandrin C not detected. These results indicated that the use of SCP powder in layering diets was effective in egg quality and for the production of lignans fortified eggs. In conclusion, dietary supplementation of Schisandra by-product with less than 5% can produce lignans-enrich eggs used as functional foods.
