Objectives: In this study, the meditation programs (${\alpha}$ version), which are properly coordinated according to the motion, breathing, and relaxation, are evaluated and researched upon to have positive effects on stress and in the area of psychology. Methods: Approved by the Clinical Trials Deliberation Committee in Oriental Medicine, Dongguk University, Ilsan Hospital, this study collected data according to the applicant's consents, demographic information and anthropometry for the Sasang Constitutional diagnosis. Sasang Constitutional diagnosis measured the beta tools by Institute of Oriental Medicine and a decision tree was made for the Sasang Constitutional questionnaires. The STAI, STAXI, BDI, and HRV were measured before and after the meditation in order to compare the effects of meditation according to Sasang Constitution. The HRV was used as a ProComP KM Tech (co). Results: 1) The positive changes available in the Time-domain analysis of heart rate variability assessment showed that the peace of mind is increased. By analyzing the Sasang constitution, So-eum In's peace of mind included a physical stability of the autonomic nervous system. 2) According to the psychological scale evaluation, each depression scale, trait anger, anger-in, state anxiety and trait anxiety index proved significantly positive effects. By analyzing the Sasang constitution, Eun-In which involved So-eum In and Tae-eum In, had positive effects. 3) The psychological scale changed the group of diagnosed depression or anxiety, it did not mean that the psychological scale changes in the depression group, but the index of the anxiety group had been significantly reduced. This program had clinical effects for anxious patients and Eum-In which involved Tae-eum In and So-eum In according to the analysis of Sasang constitution. 4) Correlations between the gender of each psychological scale showed that women have overall low correlations, but, there were no significant changes. Conclusions: The meditation program developed by adequately mixing Action, relaxation and breathing shows that it is effective for overall Eum-in physical and mental relaxation and concentration. In the future, It will have to be developed Meditation program to show the same effect for all people.

In performance, digestibility and slaughter trials, a total of forty five male weaned lambs were used to examine the effects of monensin and live yeast supplementations on growth performance, nutrient digestibility, carcass characteristics and ruminal fermentation parameters when the lambs were fed steam-flaked corn-based diets. Animals were allotted to one of three treatment diets in a completely randomized design. The three treatment diets were: (1) basal diet (CON) with steam-flaked corn as a sole grain source, (2) basal diet supplemented with monensin (MO), and (3) basal diet supplemented with live yeast (LY). Total average daily intake (ADI) was unaffected by MO and LY supplementations. LY supplementation increased (p<0.05) average daily gain (ADG) by 13.1% compared with the CON diet. Both MO and LY supplementations resulted in a significant improvement (p<0.05) of feed efficiency over the CON diet (4.47, 4.68 vs. 5.05). Hemicellulose digestibility was higher (p<0.05) for lambs in the LY supplementation group (62.4%) as compared with the CON group (55.7%), but no differences were observed in digestibilities of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF). All carcass traits were not influenced by dietary supplementations. Ruminal pH in lambs fed the LY supplemental diet was more stable than that with the CON diet (6.57 vs. 6.17). Neither MO nor LY supplementation influenced the concentration of ruminal ammonia-N and total volatile fatty acid (VFA), and molar percentages of individual VFA. Plasma urea-N concentration was decreased (p<0.05) by MO and LY supplementations, while plasma ${\beta}$-hydroxybutyrate (BHBA), glucose and other blood parameters were unaffected. In conclusion, while both MO and LY supplementations had a positive impact on feed efficiency and LY supplementation stabilized ruminal pH and improved fiber utilization, none of the supplements had the capacity to significantly enhance the carcass characteristics.

Nutritional composition and in vitro antioxidant activities of the ethanol extract of Korean traditional actinidia (Actinidia arguta) sprouts of the Otumsense variety were investigated to examine the sproutsi nutritional value. The most abundant mineral, amino acid, and fatty acid were calcium, glutamic acid, and ${\alpha}$-linolenic acid, respectively. The major free sugar of Otumsense sprouts was sucrose. The level of vitamin C, a natural antioxidant, was highest among other vitamins examined. The amount of total polyphenol was highest in the 40% ethanol extract. The 2,2'-azino-bis(3-ethylbenzo-thiazoline-6-sulphonic acid) radical scavenging activity of the 40% ethanol extract was about 94% at a concentration of $1,000{\mu}g/mL$. Malondialdehyde inhibition by the extract increased in a dose-dependent manner (from 0 to $100{\mu}g/mL$). Intracellular reactive oxygen species accumulation resulting from $H_2O_2$ treatment of PC12 cells significantly reduced when the 40% ethanol extract was present in the media compared to that in PC12 cells treated with $H_2O_2$ only.

This study analyzes on the perception of public librarians about lifelong education tasks in public library using Mann Whitney U-test, Spearman rank-order correlation coefficient, Multiple regression analysis. At the same time, analysis about re-education needs using Analytic Hierarchy Process is conducted. As result, at first, 87% of respondents feel moderate or difficult about lifelong education tasks, especially on planning task. At second, librarians who have qualification about lifelong educator feel easier (P=0.04) than others, in detail, task about lecturer liaison (P=0.04) and planning (P=0.05). Adding that, the career experience and the job difficulty of librarians has negative relationship (R=-0.217). Especially scheduling (R=-0.33) and progressing (R=-0.22) tasks show statistically meaningful. At third, as the result of Multiple regression analysis, tasks about planning (P=0.04) and library marketing (P=0.05) are selected as meaningful elements which effect overall difficulty of life long education job. As final, 91% of librarian need retraining for life long education function, as result of spearman (R=-0.210), the more librarians feels difficult about life long education jobs, the more they need retraining. Anyway, as the result of priority of retraining subjects through AHP technique, user communication (CU P=0.310), planning (PL P=0.246), library marketing (LM P=0.173) are in weight order. CR ratio shows 0.146 with permissible degree.

Despite the extensive literature on marine algae over the past few decades, a paucity of published research and studies exists on red algae. The purpose of this study was to evaluate the potential therapeutic properties of the ethanol extract of the red alga Callophyllis japonica against lipopolysaccharide (LPS)-stimulated macrophage inflammation. The C. japonica extract (CJE) significantly inhibited the nitric oxide (NO) production and the induced dose-dependent reduction of the protein and mRNA levels of inducible nitric oxide synthase and cyclooxygenase-2. Additionally, the CJE reduced the mRNA levels of inflammatory cytokines, including tumor necrosis factor-${\alpha}$, interleukin (IL)-$1{\beta}$, and IL-6. We investigated the mechanism by which the CJE inhibits NO by examining the level of mitogen-activated protein kinases (MAPKs) activation, which is an inflammation-induced signaling pathway in macrophages. The CJE significantly suppressed the LPS-induced phosphorylation of c-Jun N-terminal kinase, extracellular signal-regulated kinase and p38 MAPK. Taken together, the results of this study demonstrate that the CJE inhibits LPS-induced inflammation by blocking the MAPK pathway in macrophages.

Objectives: Galgeunhaegitang-gamibang(GH) and Samhwangseze-gamibang(SG) has been known that they are helpful for treatment of atopic dermititis clinically, but there is no report about the effect of GH and SG. So, author aimed to investigate the effects of GH and SG on atopic dermititis of NC/Nga mice. Methods : NC/Nga mice were divide into three group : normal, control, and experimental group. Atopic dermatitis was induced in the control and experimental group by spreading DNCB. Then GH was orally administered three times in a week for 8 weeks to the experimental group and SG was spreaded two times in a day for 8 weeks to the experimental group, while the control group was given normal saline. We observed changes of clinical skin severity score, serum IgE, IL-4, IL-4, IL-5, IL-6, IgM, IgGl, $IFN-{\gamma}$ and so on. We used one-way ANOVA test statistically(p<0.01). Results : Clinical skin severities of experiment group in 13 and 16weeks were significantly decreased by 48% and 55% compared to the control group. Serum IgE, IL-4, IL-5, IL-6, IgM, IgGl levels of experimental group were singnificantly decreased compared to the control group. Serum $IFN-{\gamma}$ level of the experimental group was significantly increased against control group. mRNA expression levels of IL-4, IL-5, IL-6 and CCR3 in the skin tissues of experimental group were significantly decreased compared to the control group. In contrary, $IFN-{\gamma}$y mRNA expression level were increased compared to the control group. Histological observation of the ear and skin tissues showed that the extents of inflammation and infiltrated immune cells in the epidermis and dermis of experimental group were highly deminished compared to the control group. Judging from that $IL-1{\beta}$, $TNF-{\alpha}$, IL-6 expression of gene, the effects of inflammatory cytokine revelation were significantly decreased compared to the control group. In the model inducing COX-2 activity in RAW 264.7 cell, COX-2 activity was significantly inhibited depending on the density of GH compared to the control serum. According to cell multiplication, examination of cell toxicity showed that GH is safe at the density of 10, 50, 100mg/l and even 1000mg/l. Conclusion : Accordin to the above results, it is considered that GH and SG is effective treatment for the atopic dermatitis.

Bone morphogenetic proteins(BMPs) are regarded as members of the transforming growth $factor-{\beta}$ superfamily with characteristic features in their amino acid sequences. A number of studies have demonstrated the biologic activities of BMPs, which include the induction of cartilage and bone formation. Recently there was a attempt to overcome a limitation of mass production, and economical efficieny of rh-BMPs. The method producing PTD by using bacteria have advantages of acquiry a mass of proteins. Hences, a new treatment which deliver protein employed by protein transduction domain(PTD) has been tried. The purpose of this study was to evaluate the bone regenerative effect of TATBMP-2 and TAT-HA2-BMP-2 employed by PTD from HlV-1 TAT protein for protein translocation in the rat calvarial model. An 8mm calvarial, critical size osteotomy defect was created in each of 32 male Spraque-Dawley rats(weight $250{\sim}300g$). The animals were divided into 4 groups of 32 animals each (4 animals/group/healing interval). The defect was treated with TATBMP-2/ACS(Absorbable collagen sponge) (TATBMP-2 0.1mg/ml), TAT-HA2-BMP-2/ACS(TAT-HA2-BMP-2 0.1mg/ml), ACS alone or left untreated for surgical control(negative control). The rats were sacrificed at 2 or 8 weeks postsurgery, and the results were evaluated histologically. The results were as follows: New bone formation were not significantly greater in the TATBMP-2/ACS group relative to negative, and positive control groups. New bone was evident at the defect sites in TAT-HA2-BMP-2/ACS group relative to negative, positive control and TATBMP-2 groups. There were a little bone regeneration in TATBMP-2 groups. While, enhanced local bone formation were observed in TAT-HA2-BMP-2 group. But, The results was not the same in all rat defects. Therefore, further investigations are required to develop a method. which disperse homogenously, and adhere to target cells.

Effects of acetosyringone and on Agrobacterium-mediated transformation of orchardgrass were investigated. Embryogenic calli induced from 3 varieties, Frontier, Potomac and Roughrider, were infected and co-cultured with Agrobacterium EHA101 carrying standard binary vector pIG121Hm encoding the hygromycin phosphotransferase(HPT), neomycin phosphotransferase II(NPTII) and intron-containing ${\beta}-glucuronidase$ (intron-GUS) genes in the T-DNA region. The effects of varieties and acetosyringone(AS) concentrations on transformation and the expression of the GUS gene were investigated. Inclusion of $200{\mu}M$ AS in inoculation and co-cultivation media lead to a significant increase in stable transformation efficiency. Hygromycin resistant calli were developed into complete plants via somatic embryogenesis. GUS histochemical assay and PCR analysis of transgenic plants demonstrated that transgenes were integrated into the genome of orchardgrass.

Presently, mass concrete structures are being built in federal and private projects of civil infrastructures and building structures. The hydration heat of mass concrete structures is the most important factor in the quality of concrete matrix and construction period. Moreover, internal cracks caused by hydration heat degrades durability, water tightness, and strength of concrete. To reduce hydration heat, it is necessary to blend belite cement (${\beta}-C_2S$) with industrial by-products (i.e. granulated slag and fly ash). In this experiment, 14 levels of binary binders and 4 levels of ternary binders were used to understand the effect of different replacement ratio on hydration heat, strength and microstructure (i.e. SEM and XRD) of mortar. Cumulative hydration heat at 28 days for the binary and ternary binders was affected by replacement ratio of fly ash and/or granulated slag. As fly ash content increased, hydration heat decreased. As granulated slag content increased, reduction rate of the hydration heat was lower than when fly ash was used. Especially, the hydration heat of ternary binder blended with 40% flyash and 30% granulated slag showed about 50% of hydration heat from using belite cement (P). The study results showed that the temperature rise of concrete matrix can be decreased by using blended belite binders producing low hydration heat and reasonable strength.
