  • This study was carried out to investigate the characteristics of extracellular cellulase and xylanase from Fusarium pallidoroseum and Aspergillus niger, such as enzyme activity and stability by various pH, temperature and metal ions, for application into enzymatic deinking system. The optimal temperature and pH for enzyme activity and stability of Fusarium pallidoroseum and Aspergillus niger were $50^{\circ}C$, pH 5.0 and $60^{\circ}C$, pH 9.0, respectively. Certain metal ions, calcium and cobalt, brought to elevate cellulase and xylanase activity from F. pallidoroseum and A. niger. With these results we suggest that enzymatic deinking system should be proceed at $50\~60^{\circ}C$ under their optimal pH condition.

  • There are many problems to single sports talents out of test applicants. The physical activity promotion system has been performed to all elements school students of both 5 and 6 grades in order to evaluate overall health and physical activities since 2009. This system includes some variables which could measure the students' sports latent power, so that the system could be used to single out sports talents. In this work, we propose a primary screening method that element school teachers might evaluate sports talents based on the data of the physical activity promotion system. Two more sports talent indices which are sports flexibility index and sports endurance index are defined. The selection method of sports talents is developed by using sports latent indices including sports power and cardiorespiratory indices. This method is efficient from the view of time and cost aspects, since we do not need to remeasure all elements school students again.

  • The data analysis system using Big-data is worthy to be used in various fields such as politics, traffic, natural disaster, shopping, customer management, medical care, and weather information. Particularly, the analysis of the momentum of an individual using an acceleration signal collected from a wearable device has already been widely used. However, since the data used in such a system stores only the data necessary for measuring the individual activity, it does not provide various analysis results other than the exercise amount of the individual. In this paper, I propose a system that analyzes collective behavior pattern and activity based on the acceleration signal that can be collected from personal smartphones for 24 hours a day and stored in big data. I also propose a system that sends acceleration signals and receives analysis results using standard messaging to use on various smart devices.

  • [Purpose] To determine whether physical activity (PA), primarily the recommended 60 minutes of moderate-to-vigorous PA, is associated with gut bacterial microbiota in 10-year-old children. [Methods] The Block Physical Activity Screener, which provides minutes/day PA variables, was used to determine whether the child met the PA recommendations. 16S rRNA sequencing was performed on stool samples from the children to profile the composition of their gut bacterial microbiota. Differences in alpha diversity metrics (richness, Pielou's evenness, and Faith's phylogenetic diversity) by PA were determined using linear regression, whereas beta diversity (unweighted and weighted UniFrac) relationships were assessed using PERMANOVA. Taxon relative abundance differentials were determined using DESeq2. [Results] The analytic sample included 321 children with both PA and 16S rRNA sequencing data (mean age [SD] =10.2 [0.8] years; 54.2% male; 62.9% African American), where 189 (58.9%) met the PA recommendations. After adjusting for covariates, meeting the PA recommendations as well as minutes/day PA variables were not significantly associated with gut richness, evenness, or diversity (p ≥ 0.19). However, meeting the PA recommendations (weighted UniFrac R2 = 0.014, p = 0.001) was significantly associated with distinct gut bacterial composition. These compositional differences were partly characterized by increased abundance of Megamonas and Anaerovorax as well as specific Christensenellaceae_R-7_group taxa in children with higher PA. [Conclusion] Children who met the recommendations of PA had altered gut microbiota compositions. Whether this translates to a reduced risk of obesity or associated metabolic diseases is still unclear.

  • Background: Typical difficulties encountered during in vitro fertilization (IVF) to produce embryos in pigs include poor pronucleus formation and poor-quality fertilized embryos because of high polysperm invasion. In this study, we evaluated the effects of supplementation with apple seed extract (ASE) and coculture systems on porcine in vitro-fertilized embryo culture. Methods: Slaughterhouse-derived ovaries were used to obtain cumulus-oocyte complexes (COCs). COCs were conventionally used to perform IVF. We examined the differences in apoptosis and metabolism during development following addition of ASE to normal culture and coculture systems. Matrix metalloproteinases (MMPs), cell development-related factors, and apoptotic proteins were compared in porcine embryos produced under different conditions. Results: The expression of genes related to insulin-like growth factor (IGF) signaling was increased in the coculture system. In the ASE group, early apoptosis and necrosis were reduced in fertilized embryos and the late survival rate increased. Supplementation of the coculture system with ASE led to increased expression of BCL-2 and decreased expression of Casp-3 in the cytoplasm, thereby lowering the apoptosis rate and inducing MMP expression. In addition, compared with the extract-supplemented group in normal culture, the activity of MMP-2 decreased in the coculture system supplemented with ASE, activity of MMP-9 increased, and the expression of dynactin p62 and BrdU in the cytoplasm was higher than that in the other groups. Conclusions: The coculture system increased the activity of the embryonic cytoplasm compared with the non-coculture system. Supplementation with ASE may induce cell activity and inhibit the expression of apoptotic factors.

  • Social welfare has transformed from a provider-centered welfare into a user-centered welfare. This trend have to increase the right to welfare and convenience for users. If the goal of social welfare guaranteed the respecting man's life and dignity, we had not regarded service users as the weak in the welfare system. The reinforcement of service users as the reconfirmation of welfare user's identity, mistreatment and violation of another's rights, self-determination must have the advocacy system. The advocacy for social welfare is the activity for benefit of individual, group, and community, and, protection, guarantee and maintenance of client's right. However, the client is hard to realization of right. therefore We have to support the activity for advocacy. The advocacy take aim the basic need of life and need the system for life support and safeguard client's rights. The mission of the advocacy for welfare service user is to advance the dignity, equality, self-determination, and expressed choices of individuals. We promote, expand, protect and seek to ensure the human and legal rights of individuals through the provision of information and advocacy. The advocacy system will carry out this mission in partnership with welfare service users. The goals for the advocacy system are organized into the following focus areas, which are not listed in order of priority: the majority guardian system and the support activity for service users, a predicament solution activity, service assessment, informed concent system.

  • A cell-based assay system for monitoring NF-$textsc{k}$B activity was developed to determine the influence of activated NF-$textsc{k}$B in human HaCaT cells. The pNF-$textsc{k}$B-SEAP-NPT plasmid that permits expression of the secreted alkaline phosphatase (SEAP) reported gene in response to the NF-$textsc{k}$B activity and contains neomycin phosphotransferase (NPT) gene for the geneticin resistance in host cells was constructed and transfected into human keratinocyte cell line HaCaT. Human HaCaT transfectant cells secreted the SEAP enzyme into the culture medium in a time-dependent manner until 72h. NF-$textsc{k}$B activities were measured in the SEAP reporter gene assay using a fluorescent detection method. The treatment of HaCaT cell transfectants with known antioxidants [e.g., N-acetyl-L-cysteine and vitamin C] showed inhibition of NF-$textsc{k}$B activity in a time-and concentration-dependent manner. The phorbol 12-myristate 13-acetate (PMA) known as a stimulator of NF-$textsc{k}$B expression demonstrated that it increased NF-$textsc{k}$B activity in a time- and concentration-dependent manner. This assay system could be used to determine the quantitative measurement of NF-$textsc{k}$B activity in the human skin and allow the screening of anti-inflammatory agents from various synthetic chemicals and natural products for dermatological purpose. Abbrevitions used: NF-$textsc{k}$B, nuclear factor kappa B; I-$textsc{k}$B, Inhibitory kappa B; SEAP, secreted alkaline phosphatase; NPT, neomycin phosphotransferease; PCR, polymerase chain reaction: dNTP, deoxynucleoside triphosphates; DMEM, dulbecco’s modified eagle medium; FBS, fetal bovine serum; PBs, phosphate-buffered saline; MUP, 4-methylumbellifery phosphate; NAC, N-acetyl-L-cysteine; DMSO, dimethyl sulfoxide; PMA, phorbol 12-myristate 13-acetate.

  • To investigate the effects of hot water soluble extract from Angelicae Gigantis Radix on lipid metabolism and antioxidant defense system in rats fed hypercholesterol diet, Sprague-Dawley male rats were fed either hypercholesterol diet with water or hot water soluble extract from Angelicae Gigantis Radix. Hypercholesterol diet contained 18 % beeftallow and 5 % cholesterol. After 4 weeks of experimental periods serum and liver obtained. The level of serum lipid and the activities of GOT and GPT was measured. The level of lipid and TBARS and the activity of GSH-Px was measured also. The results obtained were: 1) Food intake in the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix was low significantly. 2) In the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix of serum total lipid and total cholesterol was significantly low. 3) Serum GOT activity was significantly low in the experimental group supplied hotwater soluble extract from Angelicae Gigantis Radix. There was no difference of serum GPT activity between control and experimental group supplied hot water soluble extract from angelical Gigantis Radix. 4) There was no difference of lipid composition, TBARS level and GSH-px activity in liver between control and experimental group. The result of this study indicates that the hot water soluble extract from Angelicae Gigantis Radix was effective in decreasing the food intake of the experimental animals in the hypercholesterol diet and also effective in decreasing the levels of serum total lipid, total cholesterol and GOT activity. However it was not effective to change the level of lipid, TBARS and GSH-Px activity of liver.
