        Chitin deacetylases (CDAs) are extracellular-modifying enzymes that deacetylate chitin to produce chitosan. In insects, this modification may contribute to the affinity and/or cross-linking of chitin/chitosan-like polysaccharides for a variety of structural proteins, which may lead to diverse mechanical properties of the cuticle. We previously reported the functional importance of Group I CDAs, TcCDA1 and TcCDA2, as well as the two alternative spliced isoforms of the latter, TcCDA2a and TcCDA2b from the red flour beetle, Tribolium castaneum in molting, morphology of cuticle and movement of legs. In this study, we further analyzed protein localization, ultrastructural defects of the cuticles and leg joints after RNAi of those genes. Both proteins are mainly present in the innermost procuticle region called the “assembly zone”. Loss of function of either TcCDA1 or TcCDA2 caused disorganized chitinous horizontal laminae and vertical pore canals in both the rigid and soft cuticles. RNAi of TcCDA2b affects cuticle integrity similar to that seen in RNAi of the two alternatively spliced forms of TcCDA2. In contrast, TcCDA2a-deficient adult, like that seen in the hypomorphic phenotype produced by RNAi of TcCDA1, exhibited ruptured tendons between femur and tibia, resulting in loss of locomotion ability. These results suggest that Group I CDAs play critical roles in molting, morphology, ultrastructure and mobility in T. castaneum.

        기후변화는 전지구적 현상이며 온난화를 주패턴으로 하며 이상기상 현상의 빈도가 높아지는 등 기후예측불확실성이 증대로 이어지고 있다. 이에 따라 농업생태계의 기후변화에 대한 적응과 변화를 지표하기 위한 수단으로 말벌류 지표종을 선발하였다. 기후변화지표종 선발을 위한 지표의 객관성을 높이기 위해 지표 수준별로 개량화하였으며, 이를 통해 장수말벌, 등검은말벌, 털보말벌, 황말벌 4종을 지표종으로 선발하였다. 이 종의 장기 모니터링을 위한 무인모니터링 시스템을 개발하였다. 이를 통해 전국적 모니터링 네트워크 등의 구축이 가능할 것으로 판단된다.

        The genus Coptotriche belongs to leafmining family Tischeriidae, comprising about 60 species in the world. They live in inside leaves during immature stage; larvae feed on tissue of the leaf, producing mining trace. The pupa also spend in the mine, and emerge to become a adult from the mine. In Korea, two species, C. angusticollella and C. heinemanni, are reported and are known as pest about Rosa multiflora and Rubus crataegifolius respectively. In the present study, we review three species of genus Coptotriche in Korea with a new species. Brief descriptions and illustrations of the adults, male and female genitalia, larvae, pupae, and host plants are provided.

        산성토양의 한계지역은 인도네시아에 많이 분포해 있다. 하지만, 산성토양과 관련된 낮은 pH와 영양소는 콩 생산성의 제한요인이 된다. 따라서 콩의 식품 활용성을 위해 양분소와 생리활성성분에 대한 정보가 산성토양에 내성인 콩 품종과 함께 필요하다. 본 연구는 산성토양 내성 콩 유망계통 20개의 단백질, 지방, 지방산, 이소플라본 함량을 구명하기 위해 수행하였다. 그 결과, Tgm/Anj-888, Tgm/Anj-862 및 Tgm/Anj-858 등 3개의 계통에서 단백질함량이 높은 것으로 나타났다(≥45% dry weight=dw). 지방함량은 16.85~21.20% dw의 범위를 보였으며, 단백질함량과는 부의 상관관계를 보였다(r=- 0.64). 콩 지방은 평균적으로 팔미트산 9.42%(C16:0), 스테아릭산 2.77%(C18:0), 올레산 43.93%(C18:1), 리놀레산 38.53% (C18:2) 및 리놀렌산 5.35%(C18:3)으로 구성되었다. 총 10종류의 이소플라본이 분류되었으며, 주요성분은 말로닐-제니스틴 (29.49%)으로 그 뒤를 이어 말로닐-다이드진(19.04%), 글리시틴(16.70%)으로 밝혀졌다. 이소플라본 함량은 Tgm/Anj-995계통(2,130.2μg/g dw)에서 가장 높았으며, 그 뒤를 이어 Tgm/ Anj-784계통과 Tgm/Anj-832계통(각각 1,719.9 μg과 1,710.0 μg/g dw)인 것으로 나타났다. 본 영양소 정보는 육종가들이 산성토양에 내성인 새로운 콩 품종을 보급하는데 있어 작물 특성의 보완적인 자료로서 유용할 것이다.

        This study aims to answer the following question: Does leader brand personality dimensions mediate the relationship between self-identity expression and voting intention? The notion of political leaders as brands has been examined during the last decade by several studies and the increasing importance during the electoral process is now evident. Additionally, self-identity expressiveness, as a construct, has been connected to either psychological or sociological context regarding behavioral intention. The current research intends to build a framework for incorporating the concepts of leader brand image through brand personality dimensions, self-identity expression and voting intention for a political party. A quantitative survey through online structured questionnaire is employed in Greece and several significant theoretical and managerial contributions are provided.

        Consumer arrogance is conceptualized and defined by Ruvio & Shoham (2016) as people's proclivity for demonstrating their social superiority through the acquisition, utilization, or display of consumer goods. This new notion rooted from the symbolic meaning of consumption that suggesting consumers use products as symbols to create self-identity, to maintain their self-concept, to express their self, to convey personal and social achievements and to reflect their social status to others (Holman, 1981; Belk, 1988; Hirschman & LaBarbera, 1990). This research examines the cross-cultural validity of the Ruvio & Shoham‘s (2016) consumer arrogance scale in Turkey and Romania. Data were collected from 192 Turkish and 176 Romanian students. Confirmatory factor analysis was used to test the four-factor solution. The scale demonstrates internal consistency and validity within the two countries and across countries. The cross-cultural validation tested via configural, metric and covariance methods. The results indicated that the consumer arrogance scale is consistent across countries and it can be established as a second order construct. The nomological validity with structural equation modelling results support that consumer arrogance is predicted by materialism in both countries. This cross-national study extended consumer arrogance scale in a collectivist cultural setting and contributes to enriching cross-cultural validation research as well as consumer behavior understanding.

        Two experimental studies examine the effect of morality metaphors in advertising on consumer indulgence. The results of Experiment 1 provide evidence to suggest that consumer rebelliousness mediates the effect of morality metaphors on indulgent consumption, with Experiment 2 providing further evidence of the rebelliousness process underlying the immorality-indulgence effect.

        To overcome the low mechanical strength and corrosion behavior of a carbon steel canister at high temperature condition of a deep borehole, SiC ceramics were studied as an alternative material for the disposal canister. In this paper, a design concept for a SiC canister, along with an outer stainless steel container, was proposed, and its manufacturing feasibility was tested by fabricating several 1/3 scale canisters. The proposed canister can contain one PWR assembly. The outer container was also prepared for the string formation of SiC canisters. Thermal conductivity was measured for the SiC canister. The canister had a good thermal conductivity of above 70 W·m-1·K-1 at 100℃. The structural stability was checked under KURT environment, and it was found that the SiC ceramics did not exhibit any change for the 3 year corrosion test at 70℃. Therefore, it was concluded that SiC ceramics could be a good alternative to carbon steel in application to deep borehole disposal canisters.

        Cybalomiinae is a small subfamily of the family Crambidae, reporting 18 genera, 122 species in the world. However, this subfamily of species are still included in subfamily Pyraustinae in Korea with two species: Trichophysetis cretacea (Butler, 1879) and T. rufoterminalis (Christoph, 1881). Recently, these species transferred to Cybalomiinae by Shaffer et al. (1996). However, it was not considered in Korea.

        The family Nolidae belongs to the superfamily Noctuoidea comprising about 1,800 described species of 186 genera in the world. In China, a total of 101 species, 45 genera were recorded in ‘Fauna Sinica’ Vol.16, (1999) and in case of Japan, 110 species, 42 genera have been recorded in ‘The Standard Moth of Japan Ⅱ’, (2011). In Korea, a taxonomic study of this family has been carried out by several reseachers: Fixsen (1887), Leech (1888), Inoue (1976, 1982), Oh (2001), Sohn et al (2005), Choi (2006, 2011). However the family Nolidae has rarely been studied in Korea. A total 45 species, 25 genera have been reported from Korea (NIBR, 2016). In the present study, We overviewed the family Nolidae, with illustrations of adults in each genus, add checklist.

        과실파리류는 국내 60종의 검역 해충 가운데 42종을 차지하고 있다. 이들 대부분은 자연계 산물인 methyl eugenol (ME) 또는 raspberry ketone에 특이적으로 유인된다. 이들 유인물질을 파라핀 왁스를 이용하여 제형화하였고, 이를 대만에서 야외 유인 효과를 검증하였다. 이들 왁스 제형은 모두 델타트랩에 설치하고 8월 말경에 모니터링 한 결과 ME 왁스 제형은 오리엔탈과실파리(Bactrocera dorsalis)를 매일 60-80 마리 포획하 였다. 반면에 Cuelure 왁스제형은 오이과실파리(Bactrocera cucurbitae)와 B. tau를 유인하였다. 이러한 결과는 본 왁스제형이 이들 검역 해충에 대 한 국내 모니터링에 응용될 수 있다는 것을 제시하고 있다.
