Phosphine (PH3) resistance in the stored-products insect pests has been reported throughout the world in various insect species, including Rhyzopertha dominica, Tribolium castaneum, and Cryptolestes ferrugineus, leading farmers and fumigators to identify new fumigation tools to control PH3-resistant insect pests in storage facilities. Understanding PH3-resistance mechanisms in insects might contribute to providing clues for the development of new chemicals, including fumigants, to control various PH3-resistant insects. A proteomic study has shown 15 decreased proteins in the PH3-resistant R. dominica (CRD343 strain) in comparison to the PH3-susceptible R. dominica, and among those 15 proteins, dihydrolipoamide dehydrogenase (DLD), a protein involved in the Krebs cycle, was identified (Park et al., 2008). The DLD polymorphisms responsible for genetic resistance have disulfide active sites for PH3 binding and are highly sensitive to arsenic exposure after mutagenesis in insects (R. dominica and T. castaneum) and Caenorhabditis elegans (Schlipalius et al., 2012). Here, two PH3- resistant S. oryzae strains were used to understand the development of PH3 resistance in these insects. Acute toxicity test by PH3 on the two PH3-resistant strains was undertaken followed by ethyl formate inhibition study on cytochrome c oxidase activity. The Lineweaver-Burk plots after inhibition studies showed there were significantly difference in inhibition mode between the resistant strains and the control. The RT-qPCR analysis and the next-generation sequencing of the mitochondrial DNA revealed significant changes in metabolism and energy production. Taken together, the PH3 resistance in S. oryzae was definitely acquired by the overall transformation of biochemical reactions to overcome PH3 toxicity.

Extreme temperatures and precipitations are expected to be more frequently occurring due to the ongoing global warming over the Korean Peninsula. However, few studies have analyzed the synoptic weather patterns associated with extreme events in a warming world. Here, the atmospheric patterns related to future extreme events are first analyzed using the HadGEM3-RA regional climate model. Simulations showed that the variability of temperature and precipitation will increase in the future (2051-2100) compared to the present (1981-2005), accompanying the more frequent occurrence of extreme events. Warm advection from East China and lower latitudes, a stagnant anticyclone, and local foehn wind are responsible for the extreme temperature (daily T>38 o C) episodes in Korea. The extreme precipitation cases (>500 mm day−1 ) were mainly caused by mid-latitude cyclones approaching the Korean Peninsula, along with the enhanced Changma front by supplying water vapor into the East China Sea. These future synoptic-scale features are similar to those of present extreme events. Therefore, our results suggest that, in order to accurately understand future extreme events, we should consider not only the effects of anthropogenic greenhouse gases or aerosol increases, but also small-scale topographic conditions and the internal variations of climate systems.

Mosquitoes are transmit many dangerous disease such as malaria, yellow fever and dengue fever. So far, chemical insecticides such as DEET have been mainly used to control mosquitoes, but there are many side effects. This study used ultrasonic sounds as an alternative to chemical insecticides. We found that Culex pipiens, which are common in Korea, exhibit avoidance behavior in a specific ultrasonic frequency. Through electrophysiological recording, we have inferred that avoidance behavior is caused by different from each other mechanisms depending on the ultrasonic frequency. Using immunohistochemical staining, we analyzed the expression pattern of auditory related genes in the chordotonal organ. Quantitative real time-PCR was used to compare the expression levels of auditory related gene depending on the time of exposure to ultrasonic sounds.

한반도에서의 기후 변화는 최근까지 해충이 아니던 토착 곤충이나 비례 곤충들이 해충화 될 수 있는 가능성을 높여주고 있다. 가장 중요한 예가 토착 곤충이던 풀무치의 대량 발생에 따른 해충화가 있다. 낮은 밀도에서는 식생에 위험을 주지 않는 단독형으로 존재를 하던 풀무치가 평균온도의 상승과 강우 패턴의 변화로 대량 발생을 하여 강력한 이동성을 가지고 식생을 파괴하는 군집형으로 변화된 예가 있다. 하지만, 아직까지, 단독형에서 군집형으 로의 변화에 대한 기전이해는 완성이 되지 않은 상태이다. 기후의 변화는 겨울철 평균기온의 상승을 가져와서 한반도에서 월동이 불가능했던 해충이나 약제 저항성 계통들이 급속도로 번식할 수 있는 가능성을 열어 놓았다. 그러므로, 이러한 약제 저항성과 기후변화와 관련성에 대한 유전자 수준에서의 변화에 대한 이해가 필요한 실정이다. 위의 목적을 달성하기 위하여 우리는 다중분석학을 이용하여 연구를 진행하여 왔고, 연구 결과를 바탕으로 종 특이적이면 환경 친화적인 방제방법의 개발 연구를 진행하여 와서 이에 대한 연구결과를 발표한다(RDA Grant No. PJ010821032018).

홍합 족사 단백질은 수분이 있는 표면에서도 강한 접착력을 가진다. 홍합 연구에 대표가 되는 marine blue mussel을 통해 9가지 단백질의 구조와 기능이 보고되었으며, 이 단백질들은 홍합 족사를 구성하는 실(threads)과 플래크(plaques)를 형성한다. 알려진 바에 의하면, 히드록시기 2개가 포함된 카테콜 기 능기를 가진 DOPA 물질이 계면접착(adhesion)과 내부결합(cohesion) 과정에서 중요한 역할을 하는 것으로 알려져 있다. 본 논문에서는, 최근 10년간 활발히 연구된 계면접착과 내부응력 메카니즘에 대해 소개하고 평가하였다. 또한, 접착력을 갖는 기능기를 활용한 발전된 접착소재의 개발, 바이오접착제와 의료용 소재로 응용가능성에 대해 살펴보았다. 홍합 단백질이 다시 관심의 대상이 되면서, 바이오소재로 사용될 가능성이 커지고 있음이 주목된다.

멤브레인 파울링은 지표수를 처리하는 저압 멤브레인 기술 적용의 확장에 있어 큰 장애가 된다. 따라서 파울링 제어를 위한 주기적인 수리학적 세정기술의 최적화는 매우 중요하다. 주기적인 수리학적 세정과 이와 연관된 파울링 현상에 관한 올바른 이해는 멤브레인 세정 전략을 최적화하기 위해 매우 유용할 수 있다. 실험적으로 측정한 투과도와 전통적인 Hermia 파울링 모델 예측 치의 비교를 통해, 본 연구에서는 합성 탁도유발 시료를 처리하는 가압식 멤브레인 공정에서 30분 여과와 정세정/역세정이 포함된 1분 세정조건을 바탕으로 6번의 운전사이클을 통해 발생하는 파울링 현상을 분석하고 이를 통해 지배적인 파울링 기작을 정량적으로 이해하고자 하였다. 단독 세정에서, 첫 번째 운전사이클에서 발생하는 파울링은 완 전공극막힘 현상에 의해 주로 지배되었고 마지막 운전 사이클에서는 케이크 형성이 지배적인 파울링 기작으로 관찰되었다. 정세정과 역세정이 혼합된 경우, 파울링 속도는 감소하였으나 전반적으로 케이크 형성이 주 파울링 기작으로 관찰되었다.

1996년에 창설된 타이페이 비엔날레(TB)의 기획 메커니즘은 타이완 출신 큐레이터들의 공동 기획 체제(1996)로부터 일본 출신의 단일 큐레이터 체제(1998), 그리고 해외 큐레이터와 국내 큐레이터가 협업하는 이원 큐레이터 체제(2000-2010)를 거쳐서 다시 단일 큐레이터 체제(2012-2016)으로 회귀하기까지 다양한 과정을 겪었다. 특히 최근 단계에서는 서구 출신의 큐레이터들이 주도권을 장악해 왔다. 본 논문에서는 타이페이 비엔날레의 창립 당시 목표와 후대의 전개 양상 사이의 괴리 현상을 분석한다. 연구자는 이 행사가 타이완의 복합적인 지역 담론과 쟁점들을 제대로 반영하지 못하고 단순히 동시대 국제 비엔날레의 추세를 수용하는데 머 물러 왔으며, 그 배경에 타이페이 비엔날레의 기획 메커니즘 뒤에 작용하고 있는 ‘자기 식민 지화’의 경향이 존재한다고 주장한다.

Ethyl formate has been used for the control of insect pests by fumigation. However, there were not many reports toshow its target site of fumigant toxicity on insect pests since its first use in the agricultural industry. In the present study,we showed the presumable target sites of ethyl formate fumigation in insect pests using Myzus persicae nymphs. Afterethyl formate fumigation, the nymphs of this species were collected and the changes at the biochemical and molecularlevel were determined. The activity of cytochrome c oxidase (COX) was approximately two-fold higher after ethyl formatefumigation. In addition, the expression levels of acetylcholinesterase (AChE) decreased gradually with increasing ethylformate concentration. These two findings suggested that COX and AChE might be the major target sites of ethyl formatefumigation. In addition to these results, the analysis of lipid content using MALDI-TOF MS/MS identified 9 phospholipidsdifferently generated 2-fold higher in the ethyl formate-treated nymphs than that in the control nymphs, thereby leadingto changes in cell membrane composition in M. persicae nymphs. Therefore, the ethyl formate fumigation caused lethaleffects on M. persicae nymphs by changing COX activity, AChE gene expression, and phospholipid production.

The mosquito is a dangerous disease vector, which transfers various diseases like dengue virus, Zika virus and malaria.This study used an alternative way of mosquito repellent agents rather than chemical repellents such as DEET. We haveemployed a novel emitters of ultra-sonic sounds, which showed repellent effects to mosquito behaviors that avoid ultra-sonicsounds. Using NGS analysis after ultrasonic treatment, we found that some subsets of sensory and other related geneswere affected, indicating that ultrasonic sounds affects gene expression associated with host finding behaviors in Aedesaegypti. Additionally, we performed electrophysiological recording and behavior assay testing repellency in a chamberin Culex pipiens, which is the most common species in Korea.

Light is a necessary environmental factor for stroma formation and development of Cordyceps militaris, a well-known edible and medicinal fungus. In this study, photo morphogenesis and the blue-light receptor gene were studied using five representative strains of C. militaris. The results suggest that light was essential for colony pigmentation and could promote conidia production. Cmwc-1 gene inactivation results in thicker aerial hyphae, disordered fruit body development, a significant reduction in conidial formation, and carotenoid and cordycepin production. These characteristics were restored when the ΔCmwc-1 strains were hybridized with wild-type strains of the opposite mating type. A genomewide expression analysis revealed that there were 1042 light responsive genes in the wild-type strain and only 458 in the ΔCmwc-1 strain. Among five putative photoreceptors identified, Vivid, cryptochrome-1, and cyclobutane pyrimidine dimer photolyase are strongly induced by light in a Cmwc-1- dependent manner, while phytochrome and cryptochrome-2 were not induced. The transcription factors involved in the fungal light reaction were mainly of the Zn2Cys6 type. CmWC-1 regulates adenylosuccinate synthase, an important enzyme for adenosine de novo synthesis, which could explain the reduction in cordycepin production. Some G proteincoupled receptors that control fungal fruit body formation and the sexual cycle were regulated by CmWC-1, and the cAMP pathway involved in light signal transduction in N. crassa was not critical for the photoreaction in the fungus here. A transcriptional analysis indicated that steroid biosynthesis was more active in the ΔCmwc-1 strain, suggesting that CmWC-1 might switch the vegetative growth state to primordia differentiation by suppressing the expression of related genes.

The diamondback moth (DBM), Plutella xylostella, is a globally distributed and important economic pest. Chemical control is the primary approach to regulate populations of this pest. Chlorantraniliprole is the first commercial insecticide that belongs to the new chemical class of diamide insecticides. In this study, the resistant strain was observed 1578-fold resistance to chlorantraniliprole. Point mutation (G4946E) in ryanodine receptor (RyR) showed a high frequency. Enzyme assays indicated that glutathione S-transferase (GST) activity in the resistant strain was 2.4 times higher compared with the susceptible strain, whereas no difference was seen for P450 and esterase. In addition, the expression of two GSTs genes was up-regulated. These findings pave the way for the complete understanding of the mechanisms of diamide insecticides resistance in insects.

In the present study, we investigated the role of peripheral ionotropic receptors in artemin-induced thermal hyperalgesia in the orofacial area. Male Sprague-Dawley rats weighting 230 to 280 g were used in the study. Under anesthesia, a polyethylene tube was implanted in the subcutaneous area of the vibrissa pad, which enabled drug-injection. After subcutaneous injection of artemin, changes in air-puff thresholds and head withdrawal latency time were evaluated. Subcutaneous injection of artemin (0.5 or 1 μg) produced significant thermal hyperalgesia in a dose-dependent manner. However, subcutaneous injection of artemin showed no effect on air-puff thresholds. IRTX (4 μg), a TRPV1 receptor antagonist, D-AP5 (40 or 80 μg), an NMDA receptor antagonist, or NBQX (20 or 40 μg), an AMPA receptor antagonist, was injected subcutaneously 10 min prior to the artemin injection. Pretreatment with IRTX and D-AP5 significantly inhibited the artemin-induced thermal hyperalgesia. In contrast, pretreatment with both doses of NBQX showed no effect on artemin-induced thermal hyperalgesia. Moreover, pretreatment with H-89, a PKA inhibitor, and chelerythrine, a PKC inhibitor, decreased the artemin-induced thermal hyperalgesia. These results suggested that artemin-induced thermal hyperalgesia is mediated by the sensitized peripheral TRPV1 and NMDA receptor via activation of protein kinases.

Introduction The term “coping”refers to the actions or thoughts that people use to deal with stressful encounters (Folkman, Lazarus, Gruen, & DeLongis, 1986). Coping strategies are adopted to change the stressed person-environment relationship by either confronting and/or by regulating the emotions (Lazarus & Folkman, 1987). Research focusing on coping mechanisms has been a prolific area of study, emerged from a wide range of disciplines including psychology, sociology, and anthropology. However, for marketing researchers, questions still remain about the issue of how coping strategies are manifested in everyday consumption contexts. This represents an important area of research in that consumer coping behavior can determine critical post-purchase outcomes such as re-patronage intention, repurchase intention, and word of mouth (Raghunathan & Pham, 1999). When a service failure occurs, consumers frequently experience negative emotions and make decisions under emotionally taxing conditions (Yi & Baumgartner, 2004). Numerous scholars have made attempts to understand various consumption-related emotions and subsequent conditions corresponding to them (e.g., Raghunathan & Pham, 1999; Richins, 1997; Sujan et al., 1999). However, despite the large volume of studies focusing on consumer emotions, very few studies have examined the relationships between negative emotions with consumer coping strategies (Yi & Baumgartner, 2004). With that in mind, the primary aim of this conceptual paper was to propose a model that delineates consumer coping mechanisms derived from negatives emotions in a service failure and recovery context. Conceptual Model Coping strategies are closely linked with an individual’s attempt to manage a given stressful environment (Lazarus, 1991). Lazarus and Folkman (1984) defined coping as “constantly changing cognitive and behavioral efforts to manage specific external and/or internal demands that are appraised as taxing or exceeding the resources of the person”(p. 141). Menaghan (1983, p. 159) defined coping efforts as “specific actions (covert or overt) taken in specific situations that are intended to reduce a given problem or stress.”Duhachek (2005) defined coping construct as “the set of cognitive and behavioral processes initiated by consumers in response to emotionally arousing, stress inducing interactions with the environment aimed at bringing forth more desirable emotional states and reduced levels of stress.”Thus, the key aspects of coping includes a consequence of emotion, a dynamic process, and behavior and emotional domains of consumer responses (Duhachek, 2005). Implicit in this conceptualization is the idea that links the emotions aroused from a particular circumstance, coping strategies, and subsequent behaviors. As shown in Figure 1, our conceptual model classifies a wide range of negative emotions generated by a service failure that are linked to a set of consumer coping strategies. This will in turn influence subsequent consumer post-purchase behaviors. The behaviors will be either retaliatory (vindictive WOM, brand switching, complaining) or conciliatory (positive WOM, re-patronage intention, repurchase intention) responses. Related Literature When an individual encounters a stressful event, different negative emotions are triggered according to one’s distinct appraisals of the situation (Lazarus, 1991). These appraisals, in turn, affect how the consumer responds to the situation emotionally and behaviorally. These emotions remain powerful until the emotion eliciting problems are resolved. Proposition 1. Cognitive appraisal of the service failure situation evokes negative emotions. While some studies use combined negative emotions to explain resultant consumer behavior, others suggest separate emotion inventories (Lerner & Keltner, 2001) as different emotions trigger huge variation in cognition. Consumer negative emotions that are associated with a service failure condition can be categorized into several subsets (Watson & Clark, 1992). Many studies have utilized a limited number of negative emotions to explain consumer behavior in a service failure context (Nguyen & McColl-Kennedy, 2003). Bonifield and Cole (2006) used an appraisal-tendency framework to predict the underlying mechanism of anger and regret, associated with consumers’appraisals about service failure and their effects on post-purchase behaviors. Yi and Baumgartner (2004) focused on four negative emotions of anger, disappointment, regret, and worry in a purchase context to investigate their linkages to consumer coping strategies. Further, Tronvoll (2011) identified a set of negative emotions experienced in unfavorable service experiences leading to consumer complaint such as shame, sadness, fear, anger, and frustration. Although some marketing theorists consider the emotion of frustration to be an overlap with anger, they can be distinct emotions, especially in the context of service failure, because blaming someone else is different from blaming no particular others (Roseman, 1991). Therefore, the subsequent behavior and adapting coping strategy may differ. Thus, this study distinguished frustration separated from anger. Building on the aforementioned research, this study identified five different categories of negative emotions that are frequently found in a purchase-related situation: anger, frustration, disappointment, regret, and anxiety. Anger associates with feeling of attacking someone or yelling, resulting from an individual to be blamed on of the situation (Lazarus, 1991). Frustration tends to occur when people attribute a goal incongruent event to situational factors (Roseman, 1991). Disappointment refers to the feeling occurred due to the outcome insufficient to meet the expectation (Ortony et al., 1988). Regret is evoked when alternative option seems to be better than the selected one (Zeelenberg et al., 1994). Anxiety is linked to uncontrollable circumstances that are not directly under the purview of the provider or the customer (Ruth, Brunel, & Otnes, 2002). Proposition 1-1. Consumer negative emotions associated with a service failure situation are categorized into anger, frustration, disappointment, regret, and anxiety. Appraisal theorists contend that people use different coping strategies to reduce negative emotions accordingly (Lazarus 1991). In this study, consumer coping strategies were categorized into engagement (problem-focused, emotion-focused) and disengagement categories. Coping strategies in the engagement category involves individuals actively trying to manage, control, or change both problem- and emotion-focused aspects of the stressful person and/or environment transaction (Tobin et al., 1989). Problem-focused coping occurs when an individual tries to manage the source of the stress. Emotion-focused coping refers to where the individual changes the meaning of the event or regulates the expressing emotions (Lazarus & Folkman, 1984). In the disengagement category, mental disengagement strategy involves doing other things to take one’s mind off the problem, denial (refusing to believe that something has happened), distancing (refusing to think about the problem), and escape/avoidance (wishing problem would go away or somehow be over with). On the other hand, behavioral disengagement strategy involves consumers deciding to give up further action as nothing can be done about the situation. They acknowledge that a goal cannot be reached and that further efforts are futile. As the mechanism behind each type of coping strategy differs, the negative emotions generated from varying conditions are linked accordingly. Since anger arises from appraisals of other-responsibility, angry consumers often manifest in confrontive coping, aggressive action towards the blameworthy organization (Smith & Bolton, 2002). With respect to frustration, one is more likely to foster support-seeking coping as this does not imply blame attribution to a particular person or organization (Roseman, 1991), Further, previous work has suggested that person-related disappointment tends to result in confrontive coping behaviors such as direct complaining (Zeelenberg & Pieters, 2004) and behavioral disengagement (Yi & Baumgartner, 2004). On ther other hand, complaining about it or telling others is unlikely take place for regret as this may highlight he or she mistake (Zeelenberg & Pieters, 2004). Lastly, anxiety tends to be associated with escape behaviors (Roseman, Antoniou, & Jose, 1996). Thus, anxiety consumers often are linked with emotion-focused coping such as mental disengagement. In addition, more proactive, problem-focused coping is likely to take place as stated in some other studies (Yi & Baumgatner, 2004). Proposition 2. Negative emotions have differential impacts on consumer coping strategies. Service failure literature indicates that negative emotions influence diverse retaliatory responses. Romani Grappi and Dalli (2012) contended that negative emotions of anger, discontent, dislike, embarrassment, sadness, and worry are associated with behaviors such as switching, complaining, and negative word of mouth. Maute & Dubé(1999) also indicated that customer anger is liked to exit and negative WOM. Likewise, Blodgett et al. (1999) similarly suggested that consumers are prone to spread negative word of mouth when they perceive service failure. However, even if a particular coping strategy is activated, depending on the strategy applied, the subsequent behavior can be changed. Many researchers indicated that when a service failure is not recovered, it is more likely to lead to negative WOM and complaining behavior (Anderson, 1998). Especially, WOM behavior is more emotion-driven responses (Sundaram, Mitra, and Webster, 1998). Therefore, vindictive WOM behavior is more likely to occur when the emotions are not handled properly. In addition, Kau and Loh (2006) stated that dissatisfied customers who do not directly complain to the firm about their negative experiences may not only engage in vindictive word of mouth behavior, but also switch to another brand. Sabharwal, Soch and Kaur (2010) also suggested that dissatisfied non complaints are likely to exit the service provider more easily resulting in brand switching. Bonifield and Cole (2007) identified conciliatory behaviors to include positive WOM, willingness to return to a service provider, and feeling sympathy for the service provider. Blodgett et al. (1993) suggested that when service failure is recovered, positive word of mouth will take place. Voight (2007) revealed that when certain platform is provided for customers to express their feeling regarding their purchase, customer loyalty increases. Proposition 3. Coping strategies lead to either retaliatory responses or conciliatory responses. Proposition 3-1. Disengaging coping strategies are associated with vindictive WOM, brand switching, complaining behavior more than engaging coping strategies. Proposition 3-2. Engaging coping strategies are associated with positive WOM, re-patronage intention, re-purchase intention. Additionally, our model proposes two individual characteristics as moderators: self-efficacy and self-band connection. Especially, those with high self-brand connection are assumed to counter-argue negative brand information in a service failure situation as this concept captures a strong “self”relevant emotive tie between the brand and the consumer (Escalas, 2004). We contend that these consumers would use prior brand knowledge to neglect their negative emotions and make more brand favoring attributions following service failure. Therefore, depending on the the previous connection with the brand performing the service failure, corresponding coping strategy may change. As self-efficacy relates to the belief that an adequate coping response is available, both factors should relate to the strategies consumers use to cope (Sujan et al., 1999). Proposition 4. Individual characteristics such as self-efficacy and self-brand connection moderates the relationships between negative emotions and coping strategies. Conclusions This paper integrates a broad range of literature into a conceptual framework that delineates consumer coping strategies in a service failure and recovery context. In so doing, the model establishes clear categories for classifying negative emotions consumers experience in a service failure situation into testable elements, and it is argued that although the concept of coping is not a simple one, it should be central to any examination of the service failure and recovery phenomenon. Also, the proposed model considers where marketers’recovery efforts should be directed by describing the ways in which consumers cope with a service failure. How a firm responds to its customers when a service failure occurs can say more about that firm than any other customer interaction. If handled well, it can cultivate emotionally intense relational outcomes. However, if the firm handles the situation badly, it may cause highly negative reactions with customers taking their feedback to online reviews and social media conversations in a way that can seriously damage the firm’s reputation. Future research is needed to empirically test and extend the proposed model. Further empirical research in a particular service setting would advance marketing research as well as be of great managerial significance.

This study investigated peer-to-peer interaction during collaborative, computer-mediated reading tasks. Fourteen university EFL students in Korea worked in pairs to complete three gapfill tasks. The transcript data from these tasks were analyzed to determine: (1) how often collaboration occurs during collaborative reading tasks, (2) the ways in which peers help each other, and (3) how successful peers are in resolving the problems they collaboratively pursue. The results showed that each of these aspects of interaction varied among sets of pairs. On average, however, the participants collaborated to jointly solve 75% of the problems they encountered. They also used a range of helping behaviors during collaboration. While the participants correctly resolved nearly half of the problems they attempted, half were incorrectly answered or unresolved. Based on these findings, pedagogical implications are offered, in addition to suggestions for future research into collaborative reading tasks.
