  • Herein, 15 species of the ground beetles are reported from Jejudo. Of these, 4 species, Bradycellus subditus (Lewis,1879), Colpodes rubriolus Bates, 1883, Pentagonica angulosa Bates, 1873, and Porotachys recurvicollis(Andrewes, 1925) are listed for the first time from the Korean Peninsula. The Korean tachyine species are briefly discussed.

  • Two species new for Korea, Scolopocryptops nigrimaculatus Song, Song and Zhu, 2004 and Scolopocryptops mushashiensis Shinohara, 1984 are reported from South Korea. The Korean occurrance of S. nigrimaculatus is the first record of the species outside China, while S. mushashiensis has been known only form its type locality in Japan till now.

  • Infection with the ubiquitous fungus Aspergillus is uncommon. This organism has a low pathogenicity for man. In most patients, pulmonary Aspergilloma is the most common form of disease, and Aspergillus fumigatus is the common species. The natural history of the pulmonary aspergilloma is variable. This report reviews the feature of growing pulmonary aspergilloma for 10 years[from diameter 3cm to diameter 9cm]. This 44-year-old male patient suffered from recurrent hemoptysis for 10 years. This patient was taken removal of aspergilloma and cavernoplasty of left upper lobe. Post-operation course was uneventful.

  • In this study straightforward design procedure for unbond brace hysteretic dampers is developed. The required amount of equivalent damping to satisfy given performance acceptance criteria is obtained conveniently based on the capacity spectrum method without carrying out time-consuming nonlinear dynamic time history analysis. Then the size of the unbend braces is determined from the required equivalent damping. Parametric study is performed for the design variables such as natural period, yield strength, the stiffness after the first yield, yield stress of the unbond brace.

  • Five species in the genus Thalia of the family Salpidae are described: Thalia cicar van Soest, 1973, Thalia democratica (Forskal, 1775), Thalia orientalis Tokioka, 1937, Thalia rhomboides (Quoy and Gaimard, 1824), and Thalia sibogae van Soest, 1973. All of these species are new to the Korean fauna. A key to the Korean Thalia species is provided.
