  • 곤충의 발자국 패턴을 이용하여 곤충을 인식하고자 할 때에는 특징을 추출하기 위한 기본 단위의 영역을 추출할 필요가 있다. 이 논문에서는 기본 단위 영역의 추출을 위한 전 단계 처리 과정으로서 군집화 기법을 사용하였다. 인식의 대상이 되는 곤충들의 크기와 종류에 따라 남겨지는 발자국 패턴의 크기 및 간격이 다르게 나타난다. 따라서 이 논문에서는 패턴의 크기와 간격에 관계없이 인식의 기본 단위가 되는 영역을 추출할 수 있도록 하는 개선된 ART2 알고리즘을 제안하였다. 제안한 ART2 알고리즘에서는 군집화를 위한 임계값이 군집화의 대상이 되는 모든 패턴들의 거리를 축적한 그래프의 형태에 따라 자동으로 설정되도록 하였다. 제안한 기법으로 2 가지 종류의 곤충 발자국 패턴에 대하여 군집화를 실험한 결과 모두 바르게 군집화가 이루어짐을 알 수 있었다.

  • Objective: In this study, we analyzed the trend of patents registered prior to October 4, 2019, to understand the industrial trends in insect-derived medicinal materials used for the treatment of skin diseases. Methods: Using the WIPSON database, we collected information regarding the patents related to insect-derived materials for treating various skin diseases. Results: The patents registered prior to October 4, 2019, from Korea, Japan, the USA, China, and the EU, along with those registered under PCT were selected. There were 195 patents related to the use of insect-derived medicinal materials in treating various skin diseases such as psoriasis, inflammatory skin diseases, eczema, pruritus, and atopic dermatitis. China is mostly superior in total number of registered patents compared with the other countries. Korea was the major patent technology-holder for atopic dermatitis, but China dominated in the remaining categories of skin diseases. Upon first patent registration in 1992, there had been a continual increase in the number of patents. Especially, patents related to eczema, psoriasis, inflammatory skin disease were markedly increased. Most frequently used insect-derived medicinal materials was Scolopendra, Cicadidae Periostracum, Scorpions, Cantharides, and Batryticatus Bombyx. The insect-derived medicinal materials were generally used as a combined preparation with other medicinal materials in patents. Conclusion: This study could help to establish the basis for future research and development related treating skin diseases using insect-derived medicinal materials. In order to provide sufficient data, further study including analysis of rejected patents is needed.

  • 본 연구에서는 정서곤충을 이용한 치유프로그램 활동이 지역아동센터를 이용하는 아동 43명의 스트레스에 미치는 영향을 조사하였다. 치유프로그램에 이용된 정서곤충은 누에나방[Bombyx mori (Linnaeus)]이다. 스트레스의 정도는 타액 ɑ-아밀라아제 검사를 통해 측정하였다. 스트레스 수치를 평가하기 위한 타액 샘플 채취와 곤충 선호도에 대한 설문지는 곤충치유활동에 참여하기 전과 후에 측정되었고, 활동을 모두 마친 후에는 치유프로그램 참여 경험에 대한 만족도 점수를 평가하였다. 분석 결과, 곤충치유프로그램 활동은 참여 아동의 타액 ɑ-아밀라아제 수치를 통계적으로 낮추고, 곤충에 대한 선호도를 높여준다는 결과를 확인하였다. 누에를 이용한 치유프로그램 활동에 참가한 아동들의 만족도는 5점 만점에 4.23점이었다.

  • The Daehwangjam has excellent marketability and quality. However, precise silkworm breeding data on the recent high-temperature environment is not enough collected, and it is necessary to check whether stable Daewhangjam silkworm egg production was possible in poor environments. In this study, the timing of metamorphosis of the Daewhangjam parents Jam323 and Jam324 silkworms, in an optimal condition and a general condition similar to breeding grounds, was investigated to confirm that appropriate mating was achieved. Surprisingly, a number of female moths were discarded due to the metamorphosis of Jam324 female moths much earlier than Jam323 male moths in either an optimal or a general condition. To improve this, during the Jam324 female pupation period, the mild low-temperature of 15℃ was treated for the pupation period to delay the metamorphosis into female moths. Depending on the treatment period, the metamorphosis of the female pupa was delayed by more than 4 days, allowing normal mating with the Jam323 male moth. The eye pigments in a pupa also slowly accumulated in these treatments. In order to discover the side effects of low-temperature treatments, the voltinism of the Daewhangjam eggs was investigated, but most of them remained univoltine. Taken together, the low-temperature treatment during the female pupation period made it possible to use Jam324 female moths that were should be discarded, which means that stable and efficient management of Daewhangjam egg production is possible.
