ものづくりとしてのプロダクトデザインをまちづくりに活用して、両者を融合するデザインはできないだろうか。本研究報告は、産学協同プロジェクトを通して、企業と学生ワークショップによるものづくりを実践し、その成果をまちなかに持ち込んでまちづくり活動の支援を試行したものである。ものづくりのプロセスの中で、公共性を持ったデザインを提案し、企業の開発製品のデザインとまちづくりの支援のデザインを共存させようと試みた。まちづくりの支援の結果はフィードバックされ、企業の新しい製品開発に活用される。Can\u27t both be united by utilizing the product design as creative manufacturing for community development? In an industry-academia collaborations, we practiced product design by the company and students workshop, and tried support of community development activities. The design with public responsibility was proposed in the process of product design. The design of the development products of a company and the design of support of community development were made to live together by it. The result of support of community development will be fed back and utilized for the new product development of the company

Co-occurrence of Point Mutations in the Voltage-Gated Sodium Channel of Pyrethroid-Resistant Aedes aegypti Populations in Myanmar

Background:Single amino acid substitutions in the voltage-gated sodium channel associated with pyrethroid resistance constitute one of the main causative factors of knockdown resistance in insects. The kdr gene has been observed in several mosquito species; however, point mutations in the para gene of Aedes aegypti populations in Myanmar have not been fully characterized. The aim of the present study was to determine the types and frequencies of mutations in the para gene of Aedes aegypti collected from used tires in Yangon City, Myanmar.Methodology/Principal Findings:We determined high pyrethroid resistance in Aedes aegypti larvae at all collection sites in Yangon City, by using a simplified knockdown bioassay. We showed that V1016G and S989P mutations were widely distributed, with high frequencies (84.4% and 78.8%, respectively). By contrast, we were unable to detect I1011M (or I1011V) or L1014F mutations. F1534C mutations were also widely distributed, but with a lower frequency than the V1016G mutation (21.2%). High percentage of co-occurrence of the homozygous V1016G/S989P mutations was detected (65.7%). Additionally, co-occurrence of homozygous V1016G/F1534C mutations (2.9%) and homozygous V1016G/F1534C/S989P mutations (0.98%) were detected in the present study.Conclusions/Significance:Pyrethroid insecticides were first used for malaria control in 1992, and have since been constantly used in Myanmar. This intensive use may explain the strong selection pressure toward Aedes aegypti, because this mosquito is generally a domestic and endophagic species with a preference for indoor breeding. Extensive use of DDT for malaria control before the use of this chemical was banned may also explain the development of pyrethroid resistance in Aedes aegypti
