  • 요소수지접착제를 합판제조용 접착제와 유사하게 실험실에서 합성하고, 합성한 요소수지접착제를 증량제, 충전제, 산경화촉매제와 혼합하였다. 요소수지접착제 혼합물의 고형분량은 56.1%이고, 물은 43.9%였다. 국산재와 요소수지접착제 혼합물로 5종류의 Com-Ply를 제조하고, KS F 3101 보통합판의 인장 전단 접착력 시험 및 KS F 3104 파티클보드의 휨파괴계수 시험을 수행했다. 성능 평가된 결과는 제조된 5종류의 Com-Ply에서 모두 적합한 결과를 보여줬다. 이런 결과는 본 연구에서 사용된 요소수지접착제 혼합물이 국산재 Com-Ply제조에 적합하다는 것이다.

  • We describe here a rare case of traumatic myiasis occurred in August 2014, caused by an association of 2 Diptera species, Sarcophaga tibialis Macquart (Diptera: Sarcophagidae) and Lucilia sericata (Meigen) (Diptera: Calliphoridae), in a domestic cat in northern Italy. Species identification was based on adult male morphology. The present case is the first report of S. tibialis as an agent of myiasis in Italy, and also the first ever report of myiasis caused by an association of S. tibialis and L. sericata. The cat developed an extensive traumatic myiasis in a large wound on the rump, which was treated pharmacologically and surgically. The biology, ecology, and distribution of S. tibialis and L. sericata are also discussed. A literature review is provided on cases of myiasis caused by S. tibialis, and cases of myiasis by L. sericata involving cats worldwide and humans and animals in Italy.

  • Among non-timber forest products, Tricholoma matsutake is a high value added item. Many countries, including Korea, China, and Japan, are doing research and technology development to increase artificial cultivation and productivity. However, the production of T. matsutake is on the decline due to global warming, abnormal temperatures and pine tree pest problems. Therefore, it is necessary to identify trends in domestic and foreign research on T. matsutake, respond to preemptive research and development to preserve the genetic resources of T. matsutake and increase its productivity. Based on the correlation between keywords in the high frequency keywords, it was observed that microbial clusters of T. matsutake are mainly found in Korea. The main focus in China has been the pharmacology studies on the ingredients of T. matsutake. The main focus in Japan has been on preserving the genetic diversity and species of T. matsutake. Thus, future domestic studies of T. matsutake will require pharmacological studies on the ingredients of T. matsutake and on its genetic diversity and species conservation. In addition, unlike China and Japan, genetic keywords did not appear in Korea at high frequency. Therefore, Korea will have to proceed with research using modern molecular biology techniques.

  • Understanding of the properties of woods is important in wood utilization. Until now, traditional wooden houses(Korean-style house, Buddhist temple, royal palaces) and furniture have been made of domestic woods with the experience of a craftsman rather than the scientific knowledge on woods. Because of concrete-based houses and imported wood products and furniture, even wood craftsmen decrease in number, too. This study was carried out to collect wood samples growing in Korea and to measure wood characteristics. Anatomical, physical and mechanical properties of 37 wood species were investigated.

  • Peripheral milling is one of the most important wood machining processes in wood industry. Power consumption characteristics of twelve Korean domestic species in peripheral milling were investigated in this study. Image analysis technique was applied to extract proper data from the power consumption profiles. Average power consumption increased as cutting depth increased and specific cutting power decreased as cutting depth increased. However, no significant relationship could be found between density and power consumption and between cutting depth and surface roughness.

  • Liquid ammonia treatment known as the most effective Wood plasticization method, was applied to two typical domestic species, Pinus densiflora, Castanea crenata. Small specimens of 30mm width, 300mm length and two thicknesses, 5 or 10mm, were used. For 5mm thick Specimens, Pinus densiflora was quite well plasticized iker 4 hour liquid ammonia treatment, while Castanea crenata was not plasticized even after 4 hour treatment. Specimens of 10mm thick Pinus densiflora were hardly plasticized, but those with kerfs were bent somewhat easily, With the increase of liquid ammonia treatment time the thermal conductivity of Pinus densiflora increased, while that of Castanea crenata didn't Presteaming before liquid ammonia treatment didn't improve the plasticization of both species.

  • Domestic poultry are among the non-target species of exposure to fipronil, but limited information is available on the metabolic effects of fipronil exposure in avian. We investigated the comparative capacity of in vitro biotransformation of fipronil among chicken, duck, quail, goose, and rat. Interspecies differences in kinetic parameters were observed; the clearance rate calculations (Vmax/Km) indicated that chicken and duck are more efficient in the cytochrome P450-mediated metabolism of fipronil to sulfone than quail, goose and rat. The lower hepatic clearance of fipronil in quail, goose and rat, suggested that fipronil sulfone may serve as a biomarker to indicate fipronil exposure in these species.

  • Objective : For the purpose of developing Korean herbology of the plants to Nymphaeaceae in Korea, the literatures of the successive generations have been thoroughly investigated to prepare this article.Methods : Books and research papers about Herbology which published at home and abroad were examined.Results : A list was made about Nymphaeaceae plant which were cultivated or grew naturally in Korea, after investigated the data on domestic and foreign Nymphaeaceae plants. Out of those lists, serviceable plants were selected and with those available plants, their distributions were analysed and parts which can be used as medicines were divided into 3 categories such as oriental medicine name, scientific name and non-official name. Nymphaeaceae's properties flavor, channels they use, effects, and toxicity were also noted. Nymphaeaceae (grew in Korea) were divided into 6 classes with 10 species. Out of those, 5 classes with 5 species were found serviceable which indicates 50% of all. Out of all 10 species of Nymphaeaceae family, Nuphar genus were found 4 species, which were shown the most. Among 5 genus of Nymphaeceae species, medicinal plants were all one species each. Out of all serviceable parts in Nymphaeaceae, Etc parts took first place as 10 species. There are no toxic, the survey said.Conclusion : There were totaled to 6 genera and 10 species in Dioscoreaceae in Korea and among them medicinal plants are 5 genera, 5 species, some 50% in total.
