It is necessary to develop new methods to prevent catastrophic failure of structural material in order to avoid accidents and conserve natural and energy resources. Design of intelligent materials with a self-diagnosing function to prevent fatal fracture of structural materials was achieved by smart composites consisting of carbon fiber tows or carbon powders with a small value of ultimate elongation and glass fiber tows with a large value of ultimate elongation. The changes in electrical resistance of CF-GFRP/GFRP (carbon fiber and glass fiber-reinforced plastics/glass fiber-reinforced plastics) composites increased abruptly with increasing strain, and a tremendous change was seen at the transition point where carbon fiber tows were broken. Therefore, the composites were not to monitor damage from the early stage. On the other hand, the change in electrical resistance of CP-GFRP/GFRP (carbon powder dispersed in glass fiber-reinforced plastics/glass fiber-reinforced plastics) composites increased almost linearly in proportion to strain. CP-GFRP/GFRP composites are superior to CF-GFRP/GFRP composites in terms of their capability to monitor damage by measuring change in electrical resistance from the early stage of damage. However, the former was inferior to the latter as an application because of the difficulties of mass production and high cost. A method based on monitoring damage by measuring changes in the electrical resistance of structural materials is promising for improved reliability of the material.

Horseflies of the Tabanus immanis species group from Korea are revised taxonomically. A total of six species are arranged herein. Among them, T. vibex is new to science, and T. toshiokai is newly recorded. A key, annotated domestic records, and collection data are also provided.

Leafbeetles of subfamily Zeugophorinae in Korea are revised. Z. annulata and Z. bicolor are known to the Korean peninsula until now. This subfamily is classified into only one genus, Zeugophora Kunze. Species of the genus are revised. Among them, Zeugophora (Pedrillia) trisignata sp. nov. is described as new to science. A key, external photos, geographical data and host plants to the three species of the genus, included description of new species, are provided.

In the review of the family Anthribidae( Coleoptera; Curculionoidea) fro mthe Korean peninsula, 38 species of 27 genera are recogniced. New taxa, records, regards of misidentification and synonymies treated in this paper are as follows. A new species Uncifer triangulus sp. nov. and a new subspecies, Platystomos sellatus longicrus, subsp. nov. are described, and nine species, < Xanthoderopygus watanabei Senoh, Araeerus tarsalis Sharp, Choragus cryphaloides Sharp, Androceras flavellicornis(Sharp), Gonotropis gibbosa LeConte, Autotropis basipennis(Sharp), Uncifer difficilis(Sharp), Uncifer truncatus(Sharp), and Phaulimia confinis(Sharp)>, are reported for the first time from Korea. Exechesops elenae Egorov is dealt with a synonym of Exechesops foliatus Frieser. Keys to the subfamilies, tribes, genera and species are provided.

The present paper treats all 25 species of 4 genera of Criocerinae recorded from Korea, of them a species is newly recorded and two species probably do not occur in the country. Keys to all genera and species discussed here are given.

A sum of 84 species belonging to 44 genera under 9 families of Korean water beetles are reviewed and listed tentatively, among them 14 species are newly recorded from Korean fauna.

A total of 222 species belonging to 117 genera under 5 families of Korean Curculionoidea sensu stricto are listed, among them 72 species are newly added for Korean fauna.
