Insects are extremely abundant and diverse. Their ecological importance may outweigh that of other animal groups in both natural and managed ecosystems. To foster beneficial roles of insects while reducing their adverse effects, it is crucial to understand insect behaviors and address its implications for applied ecological questions. Therefore, my research group has focused on studying behavioral ecology of several economically important pests including whiteflies, stink bugs, bean bugs, mosquitoes, and ticks. In this talk, I will present classical and new techniques to study behaviors of the insects and some of the important findings, especially about dispersal and overwintering ecologies.

With globalization, observation was made for the need to challenge cultural homogeneity and to diversify readers’ interpretations, defining this as critical literacy. There was a lack of research on engaging the dominant in developing critical minds. This study investigated reading practices of students from privileged background when they were asked to critique what was hegemonic in a globalized society. Three Korean students were from upper-middle class backgrounds and were successful academic achievers. A qualitative research design guided the data analysis of students’ emerging patterns in reading practices. Readers took complicated paths: students were explicit in current beliefs about poverty, were critical about those naturalized view, and were bought into the dominant belief system. The reading practices that re-visit readers’ cultural view and consider diverse perspectives were suggested. Hybrid literacy practices, as opposed to having ability to read across spaces or not1 was important. Critical positions emerged when including those missing perspectives.

오징어 젓갈과 한치 젓갈의 차이를 질량분석기를 기반으로 한 전자코를 이용하여 분석한 결과 두 시료의 mass spectrum은 뚜렷한 차이를 보였다. 판별함수분석을 통해 휘발성분의 패턴을 분석한 결과 오징어 젓갈과 한치 젓갈이 뚜렷이 구분되었으며 젓갈의 양념을 제거한 후 분석하였을 때 구분이 더 잘되었다. 결과적으로 전자코를 이용하여 유사 식품 간의 차이를 충분히 구분 가능하였으며 이러한 결과는 추후 젓갈뿐 아니라 다양한 방면에 적용 가능할 것으로 보여 EMA 식품을 선별하는 데에도 도움이 될 것으로 기대된다.

In order to cope with the recent global warming and climate change that is projected to have a grave impact on agriculture worldwide, we will direct our focus on developing crops tolerant to multiple abiotic stresses including drought, cold and heat, with the following research activities conducted by three different research groups including an international research team at IRRI. 1) Development of heat/cold tolerant rice variety : Major genes conferring heat tolerance and cold resistance in rice will be identified by comparative transcriptome analyses and new molecular markers will be developed based upon these data. EMS mutagenesis and proteomics analyses will accompany this approach to supplement this gene identification and marker development efforts. Once reliable markers are obtained in this way, new varieties of heat/cold tolerant japonica rice will be bred through introgression of these genes. 2) Development of drought/heat tolerant rice variety : Through QTL mapping conducted on RILs between a drought resistant line and an elite line, genes conferring drought/heat tolerance will be identified and molecular markers will be developed using SNP/GBS genotyping methods. Using these markers, new rice varietis with drought/heat tolerance will be bred by employing marker assisted selection (MAS) as well as marker assisted backcross (MABC). 3) Identification of genes involved in multiple stress responses in ginseng and brassica : Molecular breeding of stress tolerance traits in ginseng and brassica is not well established to date. Taking advantage of the ginseng whole genome sequence data information and other comparative genomics approaches, members of the stress-response transcription factor family CBF/DREB will be identified and their functional analyses will be performed in ginseng and brassica using transcriptome profiling of both wild type and transgenic plants including the adventitious root-derived transgenic ginseng.
