PURPOSE: The purpose of this study was to conduct a comparative assessment on the satisfaction level for the two interfaces of surgical guide system (SimPlant and R2GATE), the design and convenience of manufactured surgical guides and the importance of using the surgical guides thereof by means of survey. MATERIALS AND METHODS: Hereupon, they simulated the implant surgical process by mounting the two manufactured systems of surgical guide on a dental mold, respectively. The study subjects were instructed to complete the questionnaire as to the satisfaction level upon completion of the simulated surgery. This study summarized the data of each question after collecting the completed questionnaires. Then, this study analyzed the summarized data by utilizing statistical program SPSS 20.0 (IBM). RESULTS: R2GATE had a higher value of the satisfaction level on the design and convenience of manufactures surgical guides. R2GATE group (7.33 +/- 1.26) was found to have a higher value in terms of the overall satisfaction level compared to SimPlant group (6.67 +/- 1.26) (alpha = 0.05). CONCLUSION: The user satisfaction level on the surgical guide manufactured for R2GATE system was to such an extent as it can be widely used in clinical environment. Moreover, the surgical guide manufactured as R2GATE system can guide both the length and direction of a drill simultaneously. As a result, it is highly recommended for those beginners who do not have a lot of experience in implant placement.

Aims: Dried fruits may harbour a variety of fungi especially those that can grow in low water activity conditions. Knowledge on the occurrence of fungi on dried fruits is an important step to predict the possibility of mycotoxin contamination, thus the present study was conducted to determine the occurrence of fungi on dates, figs, kiwi and raisins. Methodology and results: Based on morphological characteristics, six genera of fungi comprising eight species, Aspergillus niger, A. flavus, Penicillium corylophilum, P. glabrum, Chaetomium globosum, Fusarium sacchari, Acremonium strictum and Mycelia sterilia were identified. Three most commonly species isolated were A. niger (19 isolates), P. corylophilum (seven isolates) and A. flavus (five isolates). The less common species were C. globosum (three isolates), Mycelia sterilia (three isolates), A. strictum (one isolate) and P. glabrum (one isolate). Conclusion, significance and impact of study: Common mycotoxin producer are the fungi from the genera Aspergillus, Penicillium and Fusarium. The occurrence of toxigenic fungi on dates, figs, kiwi and raisins suggested that some of these fungi may be an important source of mycotoxin contamination.

Aims: The study was carried out to isolate and identify the spontaneously growing populations of bacteria and fungi on the surface of biologically recovered polyhydroxyalkanoate (PHA) copolymer, poly(3-hydroxybutyrate-co-3- hydroxyhexanoate) [P(3HB-co-3HHx)]. Methodology and results: Large-scale PHA biosynthesis was carried out using 300 L fermenter and a biological methodology developed in our laboratory was utilized for PHA recovery. Using standard microbiological and molecular biology techniques the naturally growing microbial populations on the surface of biologically recovered PHA were identified. Scanning electron microscopy (SEM) analysis showed that the identified bacterial (Bacillus cereus and Burkholderia cepacia) and fungal isolates (Aspergillus niger, Byssochlamys nivea, Penicillium citrinum and Penicillium griseofulvum) were able to grow on and degrade the P(3HB-co-3HHx) copolymer. Conclusion, significance and impact of study: This is the first report on biologically recovered PHA pellet addressing the occurrence of microorganisms that grew spontaneously on it during storage under laboratory conditions. Fungi appeared to be dominant over bacteria in their ability to colonize the biologically recovered PHA.

Norcolensoic acid (1) was isolated from both the fruiting bodies and the liquid culture of Lachnum virgineum. The structures of 1 was determined using spectroscopic methods. Compound 1 was isolated for the first time from this fungus. Compound 1 showed moderate antibacterial and phytotoxic activities.

The genus Biscogniauxia is a member of the Xylariaceae that has brown to dark brown and phaseoliform single cell ascospores with a conspicuous full germ slit. The isolates of Biscogniauxia collected from Mt. Nejang-san in Korea are compared with similar taxa and described. The isolation of B. nummularia var. merrillii is the first record with a precise description in Korea.

Sclerotial development of Grifola umbellata (Pers. : Fr.) Donk was investigated through microscopic examinations. The sclerotium of G. umbellata was bumpy and rugged, multi-branched, and dark-brown to black in color. The sclerotial development of G. umbellata was categorized into three stages such as sclerotial initial, development and maturation. Sclerotium development was initiated as the white fungal mass. The superficial part of white sclerotium changed into gray, light brown and then black as its development proceeded further. As a distinctive characteristic of this fungus, a large number of crystals were observed in the medulla layer of sclerotium during its maturation. For development of new sclerotium, G. umbellata formed a white sclerotial primordium on the matured sclerotium. Development of sclerotium in G. umbellata was intimately associated with rhizomorphs of Armillariella mellea and the developing sclerotia were often penetrated by rhizomorphs of A. mellea into medulla layer.

While studying Bombyx mori "Zipnuae" inoculated with an entomopathogenic fungus, Paecilomyces tenuipes, a mycoparasitic hymenoascomycete with a long neck was isolated from the silkworm rearing room. The fungus was identified as Syspastospora parasitica which has been recognized as a hyperparasite on various moniliaceous hyphomycetes. A descriptive illustration is presented in this study.
