The purpose of this study was to find out whether the service quality of food exhibitions would affect customer's behavioral intentions. The service quality of food exhibitions was classified into five sub-variables such as tangibility, reliability, responsiveness, certainty, and empathy. The survey was conducted from May 1 to May 4 in 2018 at the Food Expo in KINTEX. The results of this study were as follows. First, the effect of food service quality on behavior intention, tangibility, reliability, reactivity, and assurance played positive roles in behavior intention. Second, the result of the adjustment effect of the customer value on the service quality and the behavioral intention of the food exhibition shows that the individual control effect of the food exhibition service quality and the customer value shows confidence <sup>*</sup>customer value, reliability <sup>*</sup>customer value, empathy <sup>*</sup>Customer value had a moderating effect.

In accordance with the implementation of the ‘Framework Act on Resource Circulation’ in 2018, local governments are required to establish a basic plan for resource circulation and calculate resource circulation indicators to establish a basic resource circulation plan. However, among the resource circulation indicators, the ‘circulation utilization rate’ refers to the ratio of the actual recycling capacity to the amount of waste generated. Therefore, the status of the residues generated in the recycling process of waste should be taken into account. However, the currently announced ‘national waste generation and treatment status’ does not include the data on the residues generated during the selection process, making it difficult to calculate the actual recycling rate. In this study, each result value was derived using a material flow chart divided into five stages and a two-stage recycling process to calculate an appropriate actual recycling rate. As a result, the actual recycling rate of plastic waste among domestic waste was calculated as 71.70, and the final disposal rate was 15.25. As a result, it is judged that realistic figures were calculated compared to the actual recycling rate (100%) and final disposal rate (0%) calculated based on the national waste generation and treatment status used in most local governments and municipalities.

본 연구에서는 두충 추출물이 RBL-2H3 세포의 β-hexosaminidase의 분비 억제와 HaCaT keratinocytes 피부장벽의 회복과 관련한 filaggrin, transglutaminase-1 (TGase-1), cornified cell envelope (CE)의 발현에 미치는 영향에 관하여 연구하였다. β-hexosaminidase 방출 억제 능은 13% 효능을 확인하였고, 피부장벽기능의 회복과 관련된 인자들은 발현과 활성의 정도가 매우 우수한 것을 확인하였다. 각질형성세포의 분화를 판단할 수 있는 CE 측정에서는 두충추출물이 양성대조군보다 더 좋은 효능을 나타내기도 하였다. 따라서 두충 추출물은 β-hexosaminidase 분비 억제에 효과가 있으며, 손상된 피부장벽강화에 영향을 미치는 각질형성세포의 분화 촉진에 효과가 있음을 확인하였다. In this study, Eucommia ulmoides Oliver extracts was studied in order to see any effects on the β-hexosaminidase release suppression of RBL-2H3 cells and on the expression of filaggrin, transglutaminase-1 (TGase-1) and cornified cell envelope (CE) related to the recovery of HaCaT keratinocyte skin barrier. Results showed that Eucommia ulmoides Oliver extracts reduced β-hexosaminidase release in RBL-2H3 cells and increased the effects of Eucommia ulmoides Oliver extract on the expression of filaggrin, transglutaminase-1 (TGase-1) and cornified cell envelope (CE) in HaCaT keratinocytes. Taken together, these results suggested that Eucommia ulmoides Oliver extract may be applicable for keratinocyte differentiation.

연구는 양돈분뇨의 액비화 처리과정 중 농지환원 직전단계인 액비 후숙처리 단계에 있어서 $SCOD_{Mn}$ 농도 및 산도(pH)의 조정이 후숙액비의 이화학적성상에 미치는 영향을 알아보고 적절한 후숙 액비화 공정을 구축하기 위하여 수행하였으며, 실험결과를 요약하면 다음과 같다. 1. $SCOD_{Mn}$ 감소율은 알칼리발효 처리구에서 평균 29.9%, 인산중성화 처리구에서는 평균 36.9%로 인산 중성화 처리구가 비교적 높은 감소율을 보였다. 2. 30일간 처리 후 $SCOD_{Mn}$의 농도가 가장 낮은 처리구는 유입농도가 가장 낮았던 인산 중성화 처리구 T-6이다. 후숙 액비의 목표수준을 $SCOD_{Mn}$ 3,000 ppm 이하로 가정할 경우 후숙 발효조의 초기 투입농도는 5,500 ppm 이하로 조정하는 것이 적합하다고 사료된다. 3. 질소의 잔존율은 알칼리발효 처리구에서 평균 29.3%, 인산중성화 처리구에서 평균 38.9%로 인산중성화 처리구가 비교적 질소의 손실이 적은 한편, T-P의 경우 인산중성화 처리구에서 높은 농도(평균 1,473 ppm)로 유지되었다. 4. 본 연구를 통해 액비 후숙처리 시 '저인산-저질소'의 형태는 "알칼리발효 처리구", '고인산-고질소'의 형태는 "인산중성화 처리구"의 조건이 유리할 것으로 기대된다. This research investigated the effect of $SCOD_{Mn}$ concentrations and pH adjustment at the stage before land application, namely 2nd-aeration treatment stage of liquid fertilizer in the liquid fertilizer treatment process of swine manure on the physicochemical compositions of 2nd-aeration treated liquid fertilizer. The liquid fertilizer used in this research is the alkaline fermented liquid fertilizer of swine manure more than pH 9.0 through aeration treatment (Alkaline fermentation treatment group). About the alkaline liquid fertilizer, phosphate neutralization treatment was conducted with phosphoric acid and it was a phosphate neutralization treatment group. In 2nd-aeration treatment of liquid fertilizer for 30 days, each group was divided into alkaline treatment groups (T-1, T-2, and T-3) and phosphate neutralization treatment groups (T-4, T-5, and T-6) according to early $SCOD_{Mn}$ concentrations. The research results are as follows. 1. As for $SCOD_{Mn}$ reduction rate, the average 29.9% in alkaline treatment groups and the average 36.9% in phosphate neutralization treatment groups were shown and so the relatively high reduction rate was shown in phosphate neutralization treatment groups. 2. After finishing the experiment, the group of the lowest $SCOD_{Mn}$ concentrations was the phosphate neutralization treatment group, T-6 with the lowest inflow concentrations. In case the final goal level of 2nd-aeration treated liquid fertilizer is assumed as concentrations less than $SCOD_{Mn}$ 3,000 ppm, it would be desired that inflow concentrations of 2nd-aeration treatment groups are adjusted less than $SCOD_{Mn}$ 5,500 ppm. 3. As for the persistence rate of nitrogen, the average 29.3% in alkaline treatment groups and the average 38.9% in phosphate neutralization treatment groups were shown and so phosphate neutralization treatment groups showed the relatively low loss rate of nitrogen, meanwhile, in the case of T-P, phosphate neutralization treatment groups maintained high concentrations (average 1,473 ppm). 4. In the event of 2nd-aeration treatment of liquid fertilizer, "alkaline fermentation treatment" condition in 'low phosphate-low nitrogen' type and "phosphate neutralization treatment" condition in 'high phosphate-high nitrogen' type are expected to be favorable.
