  • Termiticidal and fungicidal activities of wood vinegar from Cinnamomum parthenoxylon (CP) stem wood have been evaluated against Coptotermes curvignathus and wood rotting fungi (Schizophyllum commune and Fomitopsis palustris). The utilized CP wood vinegar was produced in the operating temperature range 250-300℃ pyrolysis. A no-choice test was applied for evaluating termiticidal activity with 33 active termites and antifungal activity using the agar media assay. The result showed that an increase in the concentrations of CP wood vinegar significantly raised the mortality of termite. CP wood vinegar showed high termiticidal activity, organic acids (acetic acid 42.91%, 3-butenoic acid 6.89%, butanoic acid, 2-propenyl ester 2.26%), and ketones (1-hydroxy-2-propanone 5.14%, 3-methylcyclopentane-1,2-dione 2.34%) might be largely contributed to termiticidal activity in addition to other minor components. Furthermore, CP wood vinegar exhibited significant inhibition of fungal growth. These data showed that CP wood vinegar was more toxic to white-rot fungi (S. commune) than brown-rot (F. palustris). The results suggested that phenolic compounds from lignin degradation were responsible for good antifungal activity.

  • The purposes of the study are (1) to explore relationships amongst attitudes to positive/negative tourism impacts, community satisfaction, government trust, and support for tourism development and (2) to provide practical implications for policy makers how they can gain residents' support by increasing community satisfaction and government trust, which are resulted from attitudes to tourism impacts. A questionnaire is self-administered to local residents using a systematic sampling method in Ninh Hai Commune, Hoa Lu District, Ninh Binh Province, Vietnam. The results indicate community satisfaction and government trust are core factors of support for tourism development. The study highlights that to attain community satisfaction and government trust, the policy makers should especially increase positive socio-cultural and environmental impacts and minimize negative economic impacts on the community simultaneously.

  • For transformation of Pleurotus ostreatus, two novel vectors, pPhKM1 and pPhKM2, were constructed, using the regulatory sequences of the P. sajor-caju $\beta$-tubulin gene(TUB1) and the ble gene encoding phleomycin binding protein. pPhKM1 contains ble fused to the TUB1 promoter and the Schizophyllum commune GPD terminator. pPhKM2 contains ble fused to the promoter and terminator regions of P. sajor-caju TUB1. To confirm phleomycin-resistance activity, each vector was cotrans-formed with pTRura3-2 into the P. ostreatus homokaryotic $ura^-$ strain. The transforming DNA was stably integrated into the genomic DNA. Subsequently, phleomycin resistance was conferred on wild-type dikaryotic P. ostreatus by transformation with pPhKM1 or pPhKM2. This transformation system generated stable phleomycin-resistant transformants.

  • More than 120 isolates of lactic acid bacteria obtained from Kimchi was screened for antifungal activity against Aspergillus fumigatus. Approximately 10% of the isolates showed inhibitory activity and only 4.16% (five isolates) exhibited strong activity against the indicator fungus A. fumigatus. The five isolates showed a wide rang of antifungal activity against A. flavus, Fusarium moniliforme, Penicillium commune, and Rhizopus oryzae. They were identified by 16S rDNA sequencing as Lactobacillus cruvatus, L. lactis subsp. lactis, L. casei, L. pentosus, and L. sakei. The effect of Lactobacillus on mycelial growth and fungal biomass as well as its ability to produce toxic compounds were determined. The results indicate that the three species, Lactobacillus casei, L. lactis subsp. lactis, and L. pentosus, are active against A. fumigatus.

  • Eleven fungal strains previously isolated from the Mexican desert were evaluated for their capacity to use catechin as carbon source in submerged cultures. At 2 g/l of catechin, all strains grew better than the control strains, Aspergillus niger Aa-20. Aspergillus niger PSH and Penicillium commune EH2 degraded 79.33% and 76.35% with degradation rates of 0.0065 and 0.0074 g/l/h, respectively, when an initial catechin concentration of 3 g/l was used. Obtained results demonstrated the potential biotechnological capacity of these fungal strains to use condensed tannins as carbon source.

  • [ ${\beta}$ ]Glucan is a polysaccharide expressed on the cell walls of fungi. It is known that ${\beta}$-glucan is recognized by a family of C-type lectin receptors, dectin-1, which is expressed mainly on myeloid immune cells, including macrophages, neutrophils and dendritic cells. Raw 264.7 cells were treated with ${\beta}$-glucan from Schizophyllum commune. ${\beta}$-Glucan was not cytotoxic up to 400 ${\mu}g$/mL as measured by MTT assay. To measure the activity of macrophages, NO and TNF-${\alpha}$ assays were performed in Raw 264.7 cells. Treatment with ${\beta}$-glucan for 24 hr significantly increased production of NO and TNF-${\alpha}$ compared with control groups (p<0.05), indicating activation of macrophages. To measure inhibition of breast cancer cell proliferation, MTT assay was performed in MDA-MB-231 cells. Cell viability was significantly decreased in the group treated with 400 ${\mu}g$/mL of ${\beta}$-glucan for 48 hr (p<0.05) compared to the control group. However, tumor volume was decreased in the groups administered 200 ${\mu}g$ of ${\beta}$-glucan/mouse compared to the control group. These results indicate that ${\beta}$-glucan inhibits breast cancer cell growth through the induction of apoptosis.

  • This work is for redefining of cultural diversity and suggesting measurement frame by casting light on changing cultural environment according to evolution of digital convergence media. So far, most of studies tend to confuse at using media diversity and cultural diversity and resultingly the concept of cultural diversity is not founded right yet. In communications field, there is a limit to measure cultural diversity which is substantive content because analysis of media diversity is mainly focused on financial measuring and quantitation. Therefore we define digital convergence media culture as metaculture here for analysis of cultural diversity. Additionally, we catagorize and analysis cultural diversity based on this metaculture into pluralism of media activity, diversity of cultural expression, diversity of cultural diffusion and diversity of cultural cognition. These measuration variables of the four categories are factors which can lighten aspects of cultural diversity in digital convergence media environment. Analysis of these factors of the four catagories will suggest a criterion to establish policies to protect cultural diversity. The policy of cultural diversity is to construct a cultural commune in envirnment of meta culture.
