In recent years, the diamondback moth (DBM), Plutella xylostella has become one of the most important pests for cruciferous plants in the world. A new type of the thiophosphoryl pyrazole insecticide, called KHS02. Its outstanding insecticidal activity could be effective alternative against DBM. We investigated, using the comparative molecular field analysis (CoMFA) method, The structure-activity relationship of various thiophosphorylpyrazole derivatives and structure requirement for insecticidal activity. We found, the key substructures in pyrazole derivatives, the trifluoro-methyl group and the thiophosphoryl group. Both play an important role in insecticidal activity with the binding site. The three dimensional Quantitative Structure Activity Relationship (QSAR) analysis could provide useful information for the structural requirements of pyrazole insecticide as an insecticidal and the design of a new insecticide.

The purpose of this study is to investigate the characteristics of the building materials used for the housing in the urban squatter settlement. We chose Songhyun-Dong rehabilitation project started in the city of Incheon in 2000 according to the government program of housing amelioration scheme for the deteriorated low-income settlement area Detailed survey data of the physical situation of the area made for the project were examined and processed to scrutinize the traits of materials employed for the original houses. The result is given according to the location of the housing and type of plan, elevation, structure, and roof shape of the houses.
