The paper analyzed on the level of consumer member's awareness to green marketing strategies (4P's; product, price, place and promotion strategies) of Hansalim specialty shops for environmentally friendly agri-products. For the study, Hansalim-Cheonanasan members had been surveyed. Consumers purchase environmentally friendly agri-products because quality and freshness of those is good. The difference in amount of the average monthly purchase between loyal customers and disloyal customers is about 130,000 won. And customer's awareness is that the first is promotion strategy, the second product strategy, the third place strategy, the last price strategy. The average monthly purchase is related with product strategy in correlations between the 4P's each other. If Hansalim maintains a product strategy, promotes extensively and keeps their product standard, more consumers will purchase Hansalim products because the most important one of effect of green marketing strategies on consumer behavior is products. Hansalim needs to go into action to increase recognition. Some of consumers have misconcepts or don't know about the 4P's well. If Hansalim promotes positively considering interrelationship about 4P's strategies or other strategies, the consumers awareness will be changed more effectively. This study shows that balanced 4P's is better than only one superior strategy because of the correlation amomg green marketing strategies.

본 논문은 한살림서울의 돌봄사업을 사례로 생태적 복지 커먼즈의 가능성과 현실적 제약을 분석한다. 사회생태적 위기에 대항하는 커먼즈로서 한살림서울의 지역살림운동은 생태적 전환과 돌봄 사회화의 결합을 시도한다는 점에서 주목할 만하다. 지역살림운동의 일환으로서 지역돌봄은 기능적 돌봄을 넘어선 포괄적 돌봄을 추구하고 돌봄 노동 조건의 개선을 시도하는 등 좋은 돌봄의 가능성을 제시한다. 또한 한살림서울의 지역돌봄은 돌봄에 대한 포괄적 정의를 바탕으로 돌봄과 생태적 전환의 결합을 실험하고 있다. 하지만 지역돌봄의 규모는 제한적이고, 돌봄 노동의 저평가·여성화를 근본적으로 해소하기에는 역부족이다. 다만 개방적인 지역돌봄을 추구하기 때문에 복지 커먼즈와 보편적 복지 사이의 긴장은 표출되지 않고 있다. 지역살림운동에서 복지 커먼즈는 국가와 대립하는 것이 아니라 상호보완적인 관계 속에서 생태적 전환과 돌봄 사회화의 결합을 실험하고 대안을 확산시키는 데 초점이 맞춰져있다. 이와 같은 커먼즈 실험이 확산되고 공적 지원이 강화된다면 생태적 복지 커먼즈는 생태적 전환과 돌봄 사회화를 결합시킨 대안적인 위기 대응 방안으로 발전할 수 있을 것이다.

BACKGROUND: Dithiocarbamte fungicides have been used in crop cultivation for diseases protection and treatment. And cultivated agricultrual products were used as feedstuff, and residual pesticides are likely to be absorbed and transferred to livestock. But the maximum residue limits (MRLs) were not established for dithiocarbate fungicides in livestock products, and thus an analysis method was developed and validated for dithiocarbamate fungicides to establish MRLs. METHODS AND RESULTS: Samples were prepared using CS₂ trap method and detected with UV/VIS spectrophotometer. Calibration line (0.1 ~ 10 ㎍/mL) was linear with r² > 0.99. For validation, the recovery tests were carried out at three fortification levels (MLOQ, 10 MLOQ and 50 MLOQ) from livestock samples (egg, milk, beef, pork, and chicken). The results for mancozeb, propineb, and thiram ranged between 76.8 to 109.6%, 79.4 to 108.8%, and 80.2 to 107.8%, respectively and % RSD (relative standard deviation) values were below 9.5%. Furthermore, inter-laboratory analysis was performed to validate the method. CONCLUSION: All values were corresponded with the criteria ranges requested by both the CODEX (CAC/GL 40-1993, 2003) and MFDS guidelines (2016). This might be used as an official analytical method for determination of dithiocarbamate fungicides at established MRLs and monitoring.

The quality characteristics and storage stability of chicken breast meat (CBM) was investigated following the injection of whey protein (WP) as a curing ingredient. The moisture content of CBM decreased with increasing concentration of WP. The highest concentration of WP (7%) resulted in the lowest moisture and fat content and the highest protein content of CBM. Injection of WP elevated the pH and water holding capacity (WHC) of CBM. The cooking loss of CBM was significantly decreased with WP injections of 3% and higher. All WP injections increased the $L^*$ of the CBM but decreased the $a^*$ and $b^*$. WP injection increased the springiness, cohesiveness, and chewiness and decreased the hardness of the CBM. WP injection increased 2-thiobarbituric acid reactive substances (TBARS) after 3 and 7 days of storage. The volatile basic nitrogen (VBN) content of the CBM increased with increased concentrations of WP. The total microbial count (TMC) of CBM injected with WP was higher initially and after 3 days of storage. Our results showed WP injection improved the WHC of CBM but decreased the storage stability by increasing TBARS, VBN and TMC.

BACKGROUND: The residual analysis of polar pesticides has remained a challenge. It is even more difficult to simultaneously analyze multiple polar pesticides. Diquat, paraquat, and chlormequat are typical examples of highly polar pesticides. The existing methods for the analysis of diquat, paraquat and chlormequat are complex and time consuming. Therefore, a simple, quick and effective method was developed in the represent study for simultaneous analysis of diquat, paraquat and chlormequat in animal products, meat and fat using UPLC-MS/MS. METHODS AND RESULTS: Sample extraction was carried out using acidified acetonitrile and water and re- extracted with acidified acetonitrile and combine the extracts followed by centrifugation. The extract was then cleaned up with a HLB cartridge after reconstitution with acidic acetonitrile and water. The method was validated in quintuplicate at three different concentrations. The limits of detection (LOD) and quantification (LOQ) were 0.0015 and 0.005 mg/L, respectively. Matrix suppression effect was observed for all of the analytes. A seven point matrix matched calibration curve was constructed for each of the compound resulted excellent linearity with determination coefficients (R2) ≥ 0.991. Accuracy and precision of the method was calculated from the recovery and repeatability and ranged from 62.4 to 119.7% with relative standard deviation less than 18.8%. CONCLUSION: The recovery and repeatability of the developed method were in the acceptable range according to the Codex Alimentarius guideline. The developed method can be applied for the routine monitoring of diquat, paraquat, and chlormequat in animal products, meat and fat.

BACKGROUND: It is a very important task to block distribution of the agricultural products contaminated with pesticides in advance to protect consumers from residual pesticides among the agricultural products. Therefore, this study was performed to determine residual characteristics of pesticides in time-dependent manner and present scientific evidences for pre-harvest residue limit (PHRL) setting. METHODS AND RESULTS: The tested pesticides, chromafenozide and pyridalyl were sprayed onto the kale twice (seven day intervals) and then the plant samples were collected at 0 (after 3 hours), 1, 2, 3, 5, 7, and 10 days after the last spraying. Residual concentration of chromafenozide in kale decreased with 74.9% (of decreased fraction, field 1) and 85.3% (field 2) and pyridalyl decreased with 81.2% (field 1) and 85.8% (field 2), calculated by comparisons of the concentrations at 0 day and 10 days. Also biological half-lives of chromafenozide in kale were 5.6 day (field 1) and 3.4 day (field 2), and those of pyridalyl were 4.3 day (field 1) and 3.5 day (field 2). CONCLUSION(S): If the residues of chromafenozide and pyridalyl in kale from 10 days before harvest are less than 37.6 mg/kg and 58.9 mg/kg, respectively, it is expected that safe kale below MRL can be supplied on the pre-harvest day.

본 연구는 케일 중 flubendiamide의 잔류 특성을 조사하여 생산단계 잔류허용기준(PHRL, Pre-Harvest Residue Limit)을 설정하고자 하였으며, 세척용매 및 세척방법에 따른 제거효율을 알아보기 위해 수행되었다. 포장 시험은 포장 1 (경기도 안성시)과 포장 2(경기도 이천시)의 시설재배 하우스 두 곳에서 실시하였다. 농약의 안전사용기준에 따라 10일간격 2회 살포하고 0 (2시간 후), 1, 2, 3, 5, 7, 10일차에 수확하였다. Flubendiamide의 생물학적 반감기는 액체 크로마토그래피와 탠덤 질량분석기(LC-MS/MS)를 결합하여 분석한 시료 중 농약의 소실곡선으로부터 산출되었다. 분석법상의 정량한계(MLOQ)는 0.01 mg/kg 이었으며, 10 MLOQ 및 MRL (0.7 mg/kg) 두 수준에서 회수율 시험을 한 결과 각각 104.2±3.6, 101.9±10.2%의 회수율을 나타냈다. 케일 중 flubendiamide의 감소상수는 포장 1에서 0.2437, 포장 2에서 0.1981이었다. 감소상수를 사용하여 얻은 PHRL 계산식은 다음과 같이 추정되었다: 수확 10일전 잔류농도가 8.0 mg/kg 미만이라면 수확일의 잔류농도는 MRL 수준 이하일 것으로 판단된다. 세척에 의한 flubendiamide의 평균 제거율은 식초(39.8%)로 세척하였을 때 가장 높았고, 베이킹소다(31.7%), 칼슘파우더(30.2%), 중성세제(27.2%), 수돗물(15.9%) 순이었다. 본 연구의 결과는 농민과 소비자 모두에게 안전한 농산물을 생산하거나 소비하는데 유용할 것 이다.
