단감 해충의 효과적인 방제를 위하여, 현재까지 주로 화학 살충제가 사용되어 왔으나, 최근 화학 살충제의 과다 사용은 해충 저항성과 농약 잔류 문제라는 심각한 문제를 야기하고 있다. 본 연구에서는 친환경 유기농자재 (Eco-Friendly Organic Pesticides; EFOP)의 주요 단감 해충 인 감꼭지나방과 톱다리개미허리노린재에 대한 살충 활성을 검토하였다. 현재 유통되고 있는 친환경 유기농자재 11 종을 실험실 조건에서 대상 해충에 분무 처리하였다. 대조 약제는 화학 살충제인 buprofezin+dinotefuran (20+15) 수화제를 사용하였다. 감꼭지나방에 대한 유기농자재의 살충 효과를 평가하는 과정에서, 감꼭지나방 유충의 개체수 부족 문제로 인하여 배추좀나방 유충을 1차 실험충으로 사용하였으며, 세 종류의 친 환경 유기농자재를 사전 선발하였다. 선발된 친환경 유기농자재는 목초액 (EFOP-1), 회화나무, 양명아주, 멀구슬나무의 혼합추출물 (EFOP-2), Bacillus thuringiensis subsp. aizawai NT0423 (EFOP-11)이었으며, 선발된 유기농자재의 감꼭지나방 유충에 대한 살충력 실험 결과, EFOP-2 의 처리구에서 생충율이 27.7% (5 일차), 13.3% (7 일차), 6.7% (10 일차)로 가장 높은 살충 효과를 보였다. 톱다리개미허리노린재에 대한 살충 효과 평가에서는 회화나무, 양명아주, 멀구슬나무의 혼합추출물 (EFOP-2, EFOP-9)과 고삼, 데리스의 혼합추출물 (EFOP-10)이 높은 살충 효 과를 보였다. 특히 EFOP-2의 처리구에서 생충율이 20.0% (5 일차), 16.7% (10 일차)로 가장 높은 살충 효과를 보였다. 결론적으로, 친환경 유기 농자재인 EFOP-

Chemical pesticides have been used to control persimmon pests, however the overuse of the pesticides caused insect resistance. Herein we investigate the potential of eco-friendly organic pesticides (EFOP) on the control persimmon pests, Stathmopoda masinissa and Riptortus pedestris. Eleven commercially available EFOP were sprayed on the target insects in laboratory conditions. The chemical pesticide, buprofezin+dinotefuran wettable powder served as a positive control. In the bioassay against persimmon fruit moth, the mixture of Chinese scholar tree, goosefoot and subtripinnata extracts (EFOP-2) treatment showed the highest control efficacy: 27.7% (5 days) of survival rates. In the bioassay against bean bugs, the EFOP-2 showed the highest control efficacy: 20.0% (5 days) of survival rates. These results suggest that the mixture of three plants extracts (EFOP-2) has high and multiple potential in the management of the persimmon pests.

무가온 시설토마토 재배지내에서 토마토녹응애 발생양상은 4월 중하순경 최초로 발생하기 시작하여 6월 중하순경 최대 발생을 나타냈다. 하지만 야간기온이 낮을 경우 번식력이 증가하게 되고 주간기온이 높을 경우에는 분산이 활발해져 고온기인 7월에도 지속적으로 증가하는 것으 로 조사되었다. 유기농업자재 11종에 대한 토마토녹응애의 살충독성 실내검정 결과, EOIMa (Matrin 0.6%), EOICo (Clove oil 10%)가 500 배에서 각각 92.1%와 95.1%로 90% 이상의 살충효과를 보였다. 특히 EOIMa 1,000배에서는 90.4%로 90%, EOIMa 2,000배에서는 88.2%의 높은 살충효과를 보였다. 포장검정에서도 EOIMa 1,000배와 EOICo 500배는 각각 91.5%와 93.9%의 살충효과를 보여 두 약제 모두 농약을 대 체하기에 충분하였고 EOIMa의 경우 2,000배에서도 살충효과가 90%에 가까웠기 때문에 예방적 활용도 가능할 것으로 판단되었다.

Conflicting accounts of environmentally-friendly motives exist (see Chan, 2001; Hartmann & Apaolaza-Ibanez, 2012; Haws et al., 2014; Johnstone & Tan, 2015; Rashid, 2009; Royne et al., 2013). Recent research has turned to identity-society explanations (see Park & Lee, 2016). This research furthers this inquiry and narrows the gap. To understand environmentally-friendly clothing options (EFCO) motives better, this study uses uniqueness theory, which posits that consumers adopt dress different from mass fashion simply because it is unpopular (Snyder & Fromkin, 1977; Tian et al., 2001). Accordingly, environmentally-friendly attitudes should have nothing to do with the environment, but with norms, conformity, pressure (Law et al., 2004), and uniqueness. Thus, the research questions consist of: 1) is need for uniqueness in dress related to EFCO purchase intentions? 2) If so, does uniqueness relate to other EFCO motives? A survey was administered (n=220), using existing scales, to an online consumer panel All scales exhibited sufficient reliability. Pearson-Product Moment Scores and ANOVAs were used to assess variable relationships. As predicted, concern for the environment and perceived individual impact on the environment were unrelated to need for uniqueness. There was a significant and positive relationship between need for uniqueness and each of: attitudes toward EFCO and social pressure to act green. This indicates that individuals feel social pressure from important others to adapt to consumer trends. However, the manner in which they adopt mass consumer movements, such as sustainability, may be in more unique ways and via unpopular choice, such as EFCO. Finally, an ANOVA indicated that those high in uniqueness were willing to pay substantially more for EFCO.

As the general public’s awareness of the environmental problems associated with economic growth have increased, interests in eco-friendly products have also increased for the past few decades. However, many consumer surveys and sales data indicate that while many consumers believe that buying eco-friendly products is important for protection of environment, actual adoption of those products are far below what has been expected. This discrepancy between consumers’ beliefs and actions regarding eco-friendly products purchase suggests that consumers do not purchase eco-friendly products solely based on environmental concerns and environmental merits of products. Then, what is the decisive determinants of consumer’s decisions to buy of green products? Previous researches showed that many people usually are reluctant to buying green products because of high price compared to conventional products (Hopkins and Roche 2009; Thakur and Aurora 2015), but if people perceived additional value to self (e.g. functional value, social value, emotional value, economic value, epistemic value), people are willing to buy green product (Lin and Huang 2012; Jung and Kim 2014; Renfro 2010). In other words, the perceived personal value for money, associated price and benefits of product, can be importantly decisive determinants of eco-friendly buying decisions. Moreover, among many values or benefits, economic benefit such as monetary savings can be an effective factor to adaption of green product. This is because that many consumers are very sensitive to price of green products as many researchers argued, and economic benefit is so visible and computable that reduce consumer’s perceived cost. Therefore, for inducing the adaption of green product, the way of appealing and presenting product information about price premium and potential economic benefits is very important in marketing communication with consumers. However, the extant many researches have focused on highlighting that which benefits of product depending on individual difference is more attractive to people, rather than both price and benefit. There is a general lack of study on this issue in the extant literature. Furthermore, previous experiments about green products have another limitation that it is difficult to reflect the real choice of green product. Many empirical researches have focused on an attitude toward product or advertisement, a preference or a purchase intention as dependent variables, which are mostly used for predicting consumer’s choice of product. However, choice does not always and reflect the attitude toward product or advertisement, preference or purchase intention. Thus, the more research reflected actual choice of green product or conventional product is considerably needed. To fill the gap in the extant literature, this research develops and tests hypotheses on how different presentations of price premiums and monetary savings of eco-friendly products affect consumers’ choice of those product, based on extended Thaler (1985)’s Hedonic editing hypothesis of mental accounting theory, which this study proposed. In extended Thaler’s Hedonic editing hypothesis, alternative presentation (all of segregation) is added to original Thaler’s Hedonic editing hypothesis, to compensate for limitation of original hypothesis that most fragmentarily consider two attributes of product (e.g. one gain and one loss, one gain and one gain), even though attributes of products can be composed of several attributes. Therefore, this research investigates whether presenting price premiums and monetary savings in an integrated manner, a segregated manner or an all of segregated manner leads to differential choices, depending on the relative sizes of monetary gains and losses of various eco-friendly products. Additionally, this study also analyze the moderating effect of consumer’s product involvement. According to ELM model (Petty and Cacioppo 1979), the different methods of inducing persuasion may work in decision-making process, depending on level of involvement. To be specific, under high involvement, conditions the quality of the arguments contained in a message has had a greater impact on persuasion (central route). While, under low involvement conditions, peripheral cues such as attractiveness of a message source or the number of positive or negative messages have had a greater impact on persuasion (peripheral route). Therefore, this study suggests that consumers with low product involvement will more choose green product in message condition, which has the greatest number of positive information, while the consumers with low product involvement will have no difference in choice of green product, depending on different presentation. This study conducted an experiment about a choice between green product and non-green product on different presentation of monetary costs and benefits (integration, segregation, all of segregation), in each types of product (multiple gain product, mixed gain product, mixed loss product). We selected representative product for each type of product, after investigating market research (multiple gain product-washing machine; mixed gain product-LED bulb and rechargeable battery; mixed loss product-hybrid car) as shown in Table 1, and the price of each green and conventional product and cost saving amount of green product is based on real product’s attributes, in an experiment. In doing so, this study analyzed and compared the proportion of choice of green product in each conditions, by using omnibus chi-square test with SPSS 21.0 (Sharpe 2015). The findings of the empirical study shows that the effect of presentations of price and monetary savings is only significant to low product involvement consumer in all product categories, excepted for hybrid car. The results showed that low involvement consumers make many choices of green product in condition, which has the greatest number of positive information. Specifically all of segregation is the most persuasive than other presentation for LED bulb to low involvement consumer, but all of segregation is the less persuasive for rechargeable battery. This results indicate that the persuasive way of presentation is different depending on attributes of each product although LED bulb and rechargeable battery is classified as same types of product. The contribution of this study to the literature on choice of eco-friendly products in perspectives of mental accounting theory is four-fold. First of theoretical contribution, this study could extend and develop Thaler (1985)’s Hedonic editing hypothesis, by proposing alternative presentation (all of segregation). Additionally this study found that the proportion of choice of green product can be different in same type of product, depending on attribute of product. Third, this study reflected actual choice of green product by considering consumer’s choice as dependent variables, rather than attitude, preference or purchase intention. Finally, in managerial implication, this study provide managerial guidelines and strategy how to present the message about green product to increase consumer’s choice, depending on product type. Further research for extend and develop this study are currently underway.

This study was executed to deduce the factors affecting eco-friendly behaviors and attitudes, to analyse the difference of eco-friendly behaviors and attitudes between countries, and to draw the variables affecting clothing recycling behavior. The sample comprised people from the UK, China, South Korea. The results were as follows. The four factors related to eco-friendly behaviors and the five factors related to eco-friendly attitudes were derived from the results of factor analysis. In the case of eco-friendly behaviors, four eco-friendly behavior factors showed a significant difference all according to gender and country. In the case of eco-friendly attitudes, saving of natural resources for eco-friendly life, recycling for eco-friendly life, and individual preference for eco-friendly life showed a significant according to gender, also recycling for eco-friendly life, individual preference for eco-friendly life, social awareness for eco-friendly life, and company’s awareness for eco-friendly life showed a significant difference according to country. All of the variables related to clothing recycling behaviors showed the significant difference according to gender and countries. It was verified that the stronger the behaviors or attitudes for waste recycling and environmental protection, individual preference for eco-friendly life, saving of natural resources, buying eco-friendly products, and separate collection for recycling, the more positive the action to clothing recycling. The results of this study will be helpful to establish a marketing strategy for each country and to deduce a plan to attract clothing recycling form people.

Various insect pests and plant disease can outbreak in a field. For the effective control of pests and plant diseases during crop cultivation, farmers simultaneously or sequentially spray various eco-friendly agricultural materials (EFAM), chemical pesticides and microbial control agents on the same fields. It was reported that many agrochemicals are harmful to entomopathogenic fungi, especially some fungicides with broad spectrum activity that are routinely applied for the control of plant diseases. In addition, some pesticides may antagonize the potential insecticidal activity and efficiency of entomopathogenic fungi. Therefore, sometimes the utilization of fungal entomopathogen in forestry and agricultural production is limited because of the undesirable interference from some fungicides and pesticides. There is little research that examines the compatibility of these EFAMs with entomopathogenic fungi and the influence of EFAMs on the control efficacy of mycopesticides. We conducted a study of influence of pretreated eco-friendly agricultural materials on control efficacy of Isaria javanica isolate against sweet potato whitefly.

Recently, some fashion retailers have initiated sustainable actions in the form of corporate social responsibility (CSR) activities to address consumers’ social concerns. This study intends to combine the concept of CSR motivation attributions with brand extension literature in order to examine how consumers’ trust of a parent brand affects their CSR motivation attributions and ultimately their attitudes towards parent-brand CSR activities and sustainable extension lines. A self-administered online survey was conducted using scenarios describing a fast fashion retailer introducing a sustainable line. Data from 303 female U.S. consumers, aged between 18 and 34 years, were used for the statistical analysis. Data analyses were conducted using SPSS 21.0 for descriptive analysis, exploratory factor analysis, and regression analysis. The results revealed that all hypotheses were supported. The findings show that consumers’ trust of a parent brand has an indirect impact on positive attitudes towards the parent brand’s CSR activities as well as the sustainable extension product line, mediating positive evaluations of the brand’s social CSR motivations. In addition, this study suggests consumers’ prior trust of the parent brand is a variable that affects consumers’ evaluation of CSR motivation sincerity. Marketing suggestions and thoughts based on the findings of this study were provided.

This study developed an up-flow wetland providing either an eco-friendly follow-up process of medium-sized public treatment facility for livestock manure or a non-point source pollution controller near livestock farms. The four bench-scale up-flow wetlands were operated with four different bed media sets. The removal efficiencies of the wetland effluent for CODCr, TN, TP, SS were 35.2 %, 29.5 %, 31.2 % and 52.2 % for set 1(Blank, without reed, with bio-ceramic), 40.6 %, 43.4 %, 42.2 % and 55.4 % for set 2(with bio-reed&without bio-ceramic), 45.2 %, 48.7 %, 46.6 % and 66.3 % for set 3(with bio-reed&bio-ceramic), 32.9 %, 27.3 %, 29.3 % and 54.1 % for Set 4(with reed&bio ceramic), respectively. The set 3 condition having a mixture of bio-reed and bio-ceramic showed the highest efficiency in the bench-scale evaluation. This study suggests a mixture of bio-reed and bio-ceramic as suitable bed media in the construction of artificial wetlands near livestock farms. Soils including the bed media were monitored during the evaluation for trace elements. Soil analysis results were satisfied with the Korean Soil Contamination Standard. This study showed that the up-flow constructed wetland was feasible to treat the effluent livestock wastewater treatment facility.

충해 또는 병충해 관리용 친환경유기농자재로 목록공시된 제품 29종의 배추좀나방과 파밤나방 유충, 복숭아혹진딧물 성충, 꽃노랑총채벌 레 성충에 대한 살충과 섭식저해활성을 분무법과 잎침지법을 이용하여 실내에서 평가하였다. 배추좀나방 유충에 대해 추천농도 분무 또는 잎침지 시 유효성분으로 고삼 추출물 60% 단제(EOIS)와 고삼외 3종 식물 추출물(백부근, 멀구슬나무, 개박하, EIOSm) 및 고삼외 2종 식물추출물 (EOISc)을 함유한 혼합제의 살충력이 우수했다. 하지만 반량 처리 시 그 활성은 50% 이하로 감소되었다. 파밤나방 유충에 대해서는 고삼 60% 단제(EOIS)만이 우수한 살충력을 보였고, 비슷하게 꽃노랑총채벌레 성충에 대해 잎침지 후 24시간과 48시간 노출 시 85%와 95%의 살충력을 나타냈다. 복숭아혹진딧물 성충에 대한 분무시험에서 고삼 외 3종 혼합제(EOISm)와 유채외 2종 혼합제(EOIR)가 93%와 68% 살충력을 보였 는데, 농도를 배량 증가시켜도 살충력은 크게 향상되지 않는 경향을 보였다. 추천농도 잎침지에서는 고삼외 3종 혼합제(EIOSm)만이 100%의 강 한 접촉독성을 나타냈는데, 노출 시간과 농도를 증가시키면 시트로넬라오일외 1종(EOICi)과 유채외 2종 혼합제(EOIR)들의 살충력이 증가하였다. 흥미롭게도 cedar oil 16%(EOICe), 고삼 60% 단제(EOIS), 고삼외 3종 혼합제(EIOSm), 고삼외 2종 혼합제(EOISc), 미생물 89.62%(EOIM), 유 채외 2종 혼합제(EOIR), 식물추출물(EOIPe), 차나무추출물 48%(EOIT)제 등은 파밤나방에 대해 분무처리 시 강한 섭식저해활성을 나타냈다. 또한 배추좀나방 유충에 대해서도 이들 혼합제들 이외에 3종 미생물제들(EOIB, EOIM, EOIBs)과 시트로넬라오일외 1종(EOICi), 겨자외 2종 (EOIMc) 등의 식물 추출물 혼합제들이 70% 이상의 섭식저해활성을 나타냈다. 이상의 결과, 대상 곤충 종 및 유효성분이나 처리량에 따라 살충 력과 섭식저해력이 차이를 보였으나, 전체적으로 고삼추출물외 2-3종 식물추출물을 복합적으로 함유한 혼합제들의 유효력이 우수하게 나타남을 알 수 있었다.

Insect pests on cruciferous crops and their natural enemies were surveyed during 2009~2011 in Daegwallyeong highland region which has been famous for summer Kimchi cabbage production in Korea since 1970s. Totally 15 insect pests have been reported in cabbage field in Daegwallyeong. Diamondback moth (DBM, Plutella xylostella) imported cabbage worm (Artogeia rapae L.), cabbage armyworm (CAW, Mamestra brassicae L.), cabbage looper (CL, Trichoplusia ni), cabbage sawfly (Athalia rosae ruficornis Jakovlev), and turnip aphid (Liphapis pseudobrassicae (Davis)) were the dominant pest species among the 15 species. For monitoring as well as controlling insects with weak flight, yellow sticky cards (10×15㎝) were used in cabbage fields. The sticky cards were hanged on plastic stick and placed at a 2-5 m distance within cabbage field (1,000㎡). Sex pheromone traps were employed for monitoring and controlling insects with strong flight. The survey result showed that there was significantly reduced pest occurrences in treated, compared to untreated condition. Similarly, The results from the sex pheromone traps were coincident with those of sticky trap. DBM, CAW and CL were found less in the treated than untreated fields; by 67.5%, 70.6% and 44.0%, respectively. Although the control efficacy of such traps was less than that of chemical spray, the use of sticky card trap combined with sex pheromone trap could be useful management tools for controlling insect pests in cabbage fields.
