This paper presents new data on free-living heterotrophic euglenids (Euglenozoa, Protista) that occurred in the marine sediments at Cape Tribulation, Queensland, Australia. Twenty-nine species from 9 genera are described with uninterpreted records based on light microscopy, including one new taxon: Notosolenus capetribulationi n. sp. There was little evidence for endemism because the majority of heterotrophic euglenid species encountered here have been reported or were found from other habitats.

Yehliu is located at Wanli of Taipei Country with a long cape. Because the rock layer of nearby seashore contains limestone subject to sea erosion, weathering and earth movements, Yehliu is full of seawater-eroded holes as well as numerous rocks in the shape of mushroom, candle, ginger, and chessboard. All these make this 1,700-meter-long cape a geology park with rich ecological resources and a prosperous fishing village. It indicates how the geological features formed by the foundation orogeny and collapsed due to the marine erosion over thousands of years.

This study synthesized pure anatase carbon doped $TiO_2$ photocatalysts supported on a stainless steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/$TiCl_4$. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), and X-ray photoelectron spectroscopy (XPS). The XRD patterns showed that the supported $TiO_2$ nanocrystals are typically anatase, polycrystalline and body-centered tetragonal in structure. The EDS and XPS results complemented one another and confirmed the presence of carbon species in or on the $TiO_2$ layer, and the XPS data suggested the substitution of titanium in $TiO_2$ by carbon. Instead of using calcination, PAN pyrolysis was used to control the carbon content, and the mesoporosity was tailored by the applied temperature. The supported $TiO_2$ nanocrystals prepared by pyrolysis at 300, 350, and $400^{\circ}C$ for 3 h on a stainless steel mesh were actual supported carbon doped $TiO_2$ nanocrystals. Thus, $PAN/DMF/TiCl_4$ offers a facile, robust sol-gel related route for preparing supported carbon doped $TiO_2$ nanocomposites.

To gain insight on the role of pro-inflammatory cytokines in the pathogenesis and treatment of rheumatoid arthritis (RA), the phorbol 12-myristate 13-acetate (PMA)-induced IL-6 gene expression and the effect of caffeic acid phenethyl ester (CAPE) on the PMA-induced IL-6 gene expression were investigated in human fibroblast-like synoviocytes (FLSs). Synovial tissue samples were obtained from rheumatoid arthritis patients, and FLSs were isolated. The cells were stimulated with PMA (100 nM) for 6 hrs to induce IL-6 gene. The cells were pretreated with CAPE (20, 50, $100{\mu}M$) prior to PMA treatment. PMA increased IL-6 RNA expression, binding activities of transcription factors ($NF-{\kappa}B$, AP-1) to IL-6 promoter, and IL-6 promoter activity. However, CAPE inhibited PMA-induced IL-6 mRNA expression in dose-dependent manner, and also inhibited the increased binding activities of transcription factors to IL-6 promoter and IL-6 promoter activity. These results suggest that CAPE might regulate PKC-mediated IL-6 expression and inflammatory reactions in RA.

Background and Objectives : The main purpose of this study is to clarify perceptual and acoustic analysis for the patients with hypothyroidism after thyroidectomy especially focused on the characteristics of speech articulation with special reference to the consonant production. Materials and Methods : The subjects of the research were 40 male and female adults (males : 5, females : 35). They were all received radioactive iodine treatment which after total thyroidectomy. Voice samples were collected during the three stages of after surgery, pre-radioisotope treatment (RIT), and post-RIT. The acoustic analysis was conducted by using Pratt (ver.5.2.21) after measuring voice onset time (VOT). The subjective evaluation of the voices used CAPE-V. Results : A significant decrease in overall severity was displayed in the CAPE-V following RIT. It may be conjectured that this is connected to the change in voice following RIT. The loudness of the sound displayed a significant decrease in the CAPE-V following RIT. It is conjectured that this is connected to the decrease in vocal intensity following RIT. No statistically significant results were revealed for the comparative analysis on the voice onset time (VOT) in all plosives during the three periods. Conclusion : Perceptually, the overall severity of the voice with hypothyroidism was changed significantly before and after RIT. Eventhough VOT were not significantly changed, it tended to decrease VOT in patients with hypothyroidism.

The association of verotoxic E. coli and Acinetobacter spp. with various antibiotic-resistant, diarrhogenic, and nosocomial infections has been a cause for concern worldwide. E. coli and A. haemolyticus isolated on a number of selective media were screened for virulence factors, antibiotic resistance, and transformation of resistance genes. Out of 69 E. coli isolates obtained, 25 (35.23%), 14 (20.30%), and 28 (40.58%) were positive for Vtx1&2, Vtx1, and Vtx2, respectively, 49 (71.015%) for extendedspectrum beta-lactamases (ESBLs), 34 (49.28%) for serum resistance, 57 (82.61%) for cell surface hydrophobicity, 48 (69.57%) for gelatinase production, and 37 (53.62%) for hemolysin production. For the 14 A. haemolyticus isolates, only 2 (14.29%) in each case from all the samples investigated were positive for Vtx1, Vtx2 and Vtx1&2 respectively, 8 (57.14%) for ESBLs, 7 (50.00%) for serum resistance, 11 (78.57%) for cell surface hydrophobicity, 4 (28.57%) for gelatinase production, and 8 (57.14%) for hemolysin production. Although transformation occurred among the E. coli and Acinetobacter isolates (transformation frequency: $13.3{\times}10^{-7}-53.4^{-7}$), there was poor curing of the plasmid genes, a confirmation of the presence of stable antibiotic-resistant genes (DNA concentration between 42.7 and 123.8 ${\mu}g$) and intragenetic transfer of multidrug-resistant genes among the isolates. The isolates were potentially virulent and contained potentially transferable antibiotic resistance genes. Detection of virulence factors, antibiotic resistance genes, and transformation among these isolates is a very significant outcome that will influence approaches to proactive preventive and control measures and future investigations. However, continued surveillance for drug resistance among these bacteria and further investigation of the mechanism of action of their virulence factors are a necessity.

The purpose of this study was to investigate the relationship between the differences in the acoustic measurements (AVQI) and the auditory-perceptual assessments (GRBAS, CAPE-V) of the normal and vocal fold nodules. For this purpose, Total 335 voice samples were analyzed acoustically and three raters performed auditory-perceptual assessments. in the results, AVQI, G, and OS scores of the normal group were lower than those of the vocal fold nodules group. The correlations between the G scale and the OS scale were highly correlated, and the correlation between the AVQI, and auditory-perceptual results (G and OS) was also high value. The threshold values for discriminating AVQI, G, and OS between the two groups were ${\leq}4.06$, ${\leq}1$, and ${\leq}26$, respectively, and the predictive diagnostic power was 0.840, 0.860, and 0.848. In conclusion, AVQI and auditory-perceptual evaluation can improve potentiality the screening of vocal fold nodules and help to determine the diagnosis and treatment plan of voice disorders.

The purpose of this study is to investigate historical and geographical environments in the development of the Naxi costumes of Chinese ethnic minorities and their characteristics-including religious cultures and totem worship-and to suggest the direction of fashion design toward the modernization of traditional costumes. The research methodology involved the collection of materials and investigatation into the history, culture, and characteristics of Naxi costumes; in particular, the "seven-star" sheepskin cape, one of the Naxi people's important ethnic costumes as demonstrated by the women's clothing that has been designed in reflection of this traditional costume. The results are as follows. First, Naxi costumes are found to have overall coherence and distinct locality when retained in the process of modernizing the traditional costume. The theme of this work is titled "By the Light of the Moon and the Stars," which is expressed in contemporary fashion by the use of grey and dark red against a background of black, a color preferred by the Naxi people. Second, the Naxi people's seven-star sheepskin cape is a symbol of women's clothing with its characteristic patterns, shapes, and colors, and it is subject to creative modernization while retaining its unique ethnic characteristics. Third, the work expresses the contemporary stylishness of the costume while maintaining the customary decorative accessories from the Naxi people's traditional culture.

A total of 24 surface sediment samples collected from coastal region and fronting of sea cliff on Cape Cod In southeastern Massachusetts, were analyzed to Investigate the sediment transport mechanism. According to the result of grainsize analysis, the overall trend of g.k size decreases from the north(Wood End Beach) to the south(Nauset Light Beachy. The coarser materials tend to be deposited at the foreshore than at the backshore. Especially gavel content(%) Is very high in northern beaches. The lavel fraction tended to concentrate at the toe of the beach. In addition to gravel. the beach and nearshore bar also tended to be deposite of very coarse sand and the Inner fraction accumulate in the offshore bar, Grainsize analyses of sediment Indicates that the coarsest sands Including gravel accumulate In the beach and nearshore bar, the finer fraction winnowed out by wave action to be deposited In the offshore bar. The beach and nearshore bar sands and gavel are subsequently transported laterally by the wave-driven longshore drift, and finally they come to rest in the distal end of Provincetown Hook. The faller offshore sands are trnasported laterally to the south by net southward-directed longshore current.
