지속적인 기후변화로 인해 매개 곤충을 통한 다양한 신종감염병이 국제적으로 확산되고 있으며, 발생빈도 또한 증가하는 추세이다. 이러한 매개질병을 관리하기 위해서는 질병을 매개하는 매개체에 대한 정보와 지속적 인 모니터링이 필요하다. 이 연구는 제3급 법정 감염병으로 지정된 중증열성혈소판감소증후근(Severe Fever with Thrombocytopenia Syndrome, SFTS) 및 라임병(Lyme disease) 등의 매개체로 알려져 있는 참진드기를 대상으로 충남 당진 일대에서 2018년부터 2023년까지 총 6년, 4월-11월의 기간동안 월 1회 4개의 환경(무덤, 산길, 잡목림, 초지)에서 드라이아이스 유인트랩을 사용하여 발생밀도를 조사하였다. 그 결과 2018년 16,996마리, 2019년 16,698마리, 2020년 6,417마리, 2021년 7,380마리, 2022년 3,451마리, 2023년 3,465마리로, 총 54,407마리가 채집되 었으며, 초지에서 가장 많이 채집되었다. 채집된 참진드기는 2속 3종으로 작은소피참진드기(Haemaphysalis longicornis), 개피참진드기(H. flava), 일본참진드기(Ixodes nipponensis)이며, 작은소피참진드기 (H. longicornis) 가 42,489마리(78.09%)로 높은 우점도를 보였으며, SFTS 보유 여부를 확인하기 위해 RNA 추출 및 Nested RT-PCR 단계를 걸쳐 전기영동을 수행하였으나 양성 검체는 0건으로 확인되었다. 이러한 연구 결과는 SFTS의 주요 매개 체인 참진드기 발생 양상 파악 및 매개 질병 관리 전략 수립에 기초 자료로서 활용될 수 있을 것으로 사료된다.

국립기상연구소의 보고에 의하면 최근 한반도의 기온 상승으로 인해 온대내륙성 기후형에 속했던 지점은 온대해양성 기후형으로, 온대해양성 기후형은 아열대습윤 기후형으로 변화하고 있다. 이러한 한반도의 기후 변화는 환경 변인에 민감한 질병 매개 곤충의 분포와 밀도 변화에 영향을 미칠 수 있어 지속적인 모니터링이 중요하다. 이 연구는 철새도래지 내 발생 및 유입될 수 있는 모기와 관련 바이러스 감염률을 확인하기 위해 충남 당진의 철새도래지에서 BG-sentinel trap 및 LED trap을 사용하여 2021년부터 2023년까지 4-11월간 월 2회 수행하 였다. 채집된 모기는 총 3,723마리로, 4속 16종을 확인하였다. 그 중 금빛숲모기 (Aedes (Aedimorphus) vexans nipponii) 가 1,711마리(45.96%)로 가장 높은 우점도를 나타냈으며, 흰줄숲모기 (A. (Stegomyia) albopictus) 와 큰검 정들모기 (Armigeres (Armigeres) subalbatus) 각각 588마리(15.79%), 빨간집모기 (Culex (Culex) pipiens pallens) 269마리(7.23%)로 나타났다. 채집된 모기의 Flavi-virus 감염 여부를 확인하기 위해 RNA 추출 및 RT-PCR을 통해 확인하였으나, 모두 음성으로 확인되었다. 이러한 연구 결과들은 기후변화에 맞추어 변화하는 감염병 매개 모기 의 발생 현황을 감시·예측하는데 유의한 자료로 활용될 수 있으며, 향후 모기 매개 질환 발생을 예측하기 위한 기초 자료로 활용될 수 있을 것으로 사료된다.

Modern men are much more interested in their appearance than ever before, as well as showing an increased need for uniqueness in order to construct their own sphere and pursue differentiation from others. Besides, changes in life style and the aesthetic sense are causing men to pursue various kinds of clothing benefits so that they want a suit with characteristics beyond the stereotyped design and style. They have started to be actively engaged in clothing purchases, forming a driving force for the growth of the male suit market. Hence, this study has significance in that it offers data conducive to consumers’ custom suit purchase by reviewing data on the present condition of the custom suit market and bespoke suits. In addition, it aims to give a summary on the theoretical bases of preceding studies, including the need for uniqueness, pursuit of clothing benefit and concern for the appearance of male consumers, as well as examining the factors that influence on their bespoke suit purchase intentions. Accordingly, this work intends to construct a basic environment for consumers to approach the custom suit market easily and pave the way for male suit markets through offering marketing data and information that is helpful for custom suit-related markets.

Microfluidics based on nanobio sensors technologies can provide convenient and accurate diagnosis tools. In this talk, we present recent developments of nanobio sensors & diagnosis chip using microfluidics, with special emphasis on disposable plastic devices format. In detail, we overview of the common methods used in the fabrication of polymer microfluidic systems, including replica and injection mold-ing. Also we explain the different methods by which on-chip operations—such as the pumping and valving of fluid flow, the mixing of different reagents, and the separation and detection of different biochemical species implemented in a microfluidic format. Finally, a few select biotechnological applications of microfluidics are presented to illustrate both the utility of this technology and its potential applications with insect models in the near future.

Indianmeal moth Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) is an economical pest of stored grains and their products, causing severe loss by feeding and producing silken web containing frass and exuvia. An ectoparasitoid Bracon hebetor Say (Hymenoptera, Braconidae) attacks this pest as a natural enemy and induce paralysis and developmental arrest in it. At molecular level its venom induce many physiological changes in host P. interpunctella to make it suitable source of food and development for its young ones. To explore these physiological changes at molecular level in P. interpunctella, we observed expression level of different genes having different functions related to immunity, defense and development at different intervals followed by B. hebetor envenomation. Fifth instar day 5 old larvae of P. interpunctella were used in experiment. Our results showed that B. hebetor envenomation effect the gene expression differently in host P. interpunctella. This basic study will be the starting point to understand the role of envenomation in host regulation studies.

Indianmeal moth Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) is an important pest of stored grains products. As a natural enemy, an ectoparasitoid Bracon hebetor Say (Hymenoptera, Braconidae) has been used to control Lepidopteran pest insects. Venom from parasitoid female alters many physiological functions in host insects. However, mechanism of physiological response of host insects against envenomation and parasitization is not clear. Here we observed the effect of B. hebetor envenomation on the gene expression (shsp, hsp70, grp78 and hsp90) in P. interpunctella at different time intervals of post envenomation. Fifth instar day 5 larvae of P. interpunctella were used in experiment to observe the effect of envenomation. Our results showed that parasitoid envenomation affected the gene expression differently in host insect. This study will provide comprehensive insights on physiological and biochemical mechanism in host-parasitoid relationships.

This study focuses on the implications of the acceptability contrast of the locative inversion (LI) and presentational there insertion (PTI) constructions when considering some recent accounts of Extended Projection Principle (EPP) effects (see, among others, Chomsky 1995, 2000, Kim 2002, Lasnik 2001). For this purpose, we use Kim and Lee`s (to appear) acceptability judgment test composed of LI and PTI constructions, which was administered to native English speaking subjects. Results show judgment contrasts and confirm the slightly degraded nature of the LI constructions. In regard to the theoretical importance of the EPP, why perceptions of the contrasts differ is captured through a theoretical analysis.
