‘전국 폐기물 발생 및 처리현황’(환경부, 2014)에 따르면, 국내의 전국 폐기물 총 발생량은 매년 증가하는 추세이다. 건설 폐기물을 포함한 ‘14년도 총 폐기물 발생량은 388,486톤/일에 달하며, 지정폐기물을 포함하면 폐기물 발생량은 더 증가한다. 이렇게 발생한 폐기물은 매립, 소각, 재활용, 해역배출로 처리되었다. 하지만 국내의 육상 폐기물 해역배출은 런던협약에 ‘16년부터는 전면 금지되었으며, 매립과 재활용을 통한 폐기물의 처리는 한계가 있다. 지속적으로 발생량이 증가하는 폐기물의 처리와 지정폐기물, 재활용 금지 및 제한대상 폐기물을 처리하기 위하여 폐기물의 소각처리가 필수적으로 요구된다. 국내에서는 정책적으로 폐기물 소각시설의 폐자원에너지 회수와 사용에 대해 집중하고 있으며, 2015년에 폐기물 소각시설의 소각열에너지 회수·사용률 산정방법을 확정하여 2018년 1월 1일부터 자원순환기본법을 통해 시행할 것을 예고하였다. 사업장폐기물 소각시설의 소각열에너지 회수·사용률 산정방법에 따르면 열정산법을 이용해 입열과 출열을 산출하여 소각시설의 효율을 계산한다. 소각로의 방열손실은 에너지의 회수 효율을 낮추는 출열 항목 중 한가지로 각 시설마다 측정하여 평가되어야 한다. 현재 방열손실 평가를 위한 소각로의 벽면 온도 측정은 지점측정법을 이용하여 실측되고 있다. 하지만 접촉식 온도 측정은 대상의 접촉 지점마다 온도가 다르게 측정 될 수 있으므로 대상 시설의 평균 표면온도를 정확하게 측정하는 것이 어렵다. 비접촉 방식으로 온도를 측정하는 적외선 열화상 카메라는 넓은 면적의 온도를 동시에 측정 가능하며 대상 시설의 평균 온도를 비교적 정확하게 측정 할 수 있다. 따라서 본 연구에서는 폐기물 소각시설의 출열 항목 중 방열손실의 측정 및 평가를 위해 적외선 열화상 카메라를 이용하였으며, 소각로 표면 온도 측정방법과 소각시설의 방열손실 산정 방법을 정립하였다.

현재 국내 폐기물은 발생억제(Reduce), 재이용(Reuse), 재활용(Recycle)의 3R 정책을 바탕으로 발생량 감축 및 재활용을 유도하고 있다. 하지만 재활용이 불가능한 상태의 폐기물과 재활용처리 후 발생하는 부산물 등은 최종적으로 소각과 매립을 통하여 처리되고 있다. 이처럼 소각처리 될 수밖에 없는 폐기물은 단순 소각처리 되는 양을 최소화하고 연소과정에서 발생되는 에너지를 회수(Recovery)하여 열 또는 전력에너지로 적극 활용해야 할 필요가 있다. 하지만 현행 에너지 회수기준의 회수율 산정 방법은 생산에너지를 기준으로 하여 생산 후 버려지는 에너지도 포함됨으로써 실질적인 회수로 판단하기에 한계가 존재한다. 즉, 현행 에너지 회수기준은 회수율 증진을 위한 기술개발 및 시설개선 등과 같은 도입취지와 목적을 충분히 반영하지 못하고 있는 실정이다. 또한 에너지회수율 산정의 핵심 매개변수인 폐기물 저위발열량에 대한 측정 및 분석 방법의 명확한 공통기준이 없어 객관성이 부족한 상황이다. 이에 2015년 「폐기물관리법」 시행규칙 제3조제2항 “폐자원에너지 회수·사용률 산정방법”에서는 폐기물 소각 처리를 통하여 회수되는 에너지 중 실제 사용되는 에너지의 비율을 바탕으로 하는 에너지 회수·사용률 산정방법과 투입 폐기물로부터 기원하는 정확한 투입에너지 산정을 위한 저위발열량 산정방법을 제정·고시하였다. 본 연구에서는 새로 제정된 “폐자원에너지 회수·사용률 산정방법”을 바탕으로 국내 사업장폐기물 소각시설에서의 폐기물 저위발열량과 에너지 회수·사용률을 산정하였다. 산정에 요구되는 데이터는 3개월간의 업체 내 실제 계측데이터를 활용하였으며, 계측이 불가능한 항목은 현장 측정 결과를 적용하였다. 대상시설은 스토커소각로 3기(시설 A, B, C)와 로터리킬른-스토커 병합방식 소각로 1기(시설 D)로 하였으며, 주별·월별·분기별로 구분하여 산정 결과를 도출하였다. 분기별 산정결과 폐기물 저위발열량의 경우 시설 A, B, C, D 각각 3,684kcal/kg, 2,960kcal/kg, 3,081kcal/kg, 2,794kcal/kg로 산정되었으며, 에너지회수·사용률은 각각 54.2%, 54.6%, 64.7%, 52.1%로 산정되었다. 이러한 결과는 에너지생산량 기준의 에너지회수율 대비 약 5∼20% 차이를 나타냈으며, 에너지회수·사용률을 높이기 위해서는 생산된 에너지 중 판매량을 최대화 하는 것이 가장 중요하고 효과적일 것으로 판단된다. 또한 장기적으로 보조연료 투입량과 전력 사용량 감축을 위한 기술개발과 시설공정 및 운영방식의 개선이 필요할 것으로 사료된다.

With the purpose of improving ginsenoside production in Korean wild ginseng (Panax ginseng Meyer) mutant adventitious root lines, a synthetic gene encoding squalene synthase (PgSS2) was placed under the control of 35S promoter and transferred to Panax ginseng. Embryogenic callus obtained from ginseng adventitious root lines were transformed by infection with A. tumefaciens strain EHA105 containing the PgSS2 gene. Ten phosphinothricin-resistant plants were generated on selection medium, and the transgene integration and expression in these plants were confirmed by PAT test strip, RT-PCR and Southern hybridization. Ginsenoside analysis by HPLC revealed that the total contents of the 8 ginsenoside types (Rg1, Re, Rf, Rh1, Rb1, Rc, Rb2, Rd) in transgenic adventitious root lines were about 1.6-fold higher than that of the mutant control line (MCL1). This transformation method may facilitate the improvement of Panax ginseng in terms of the accumulation levels of ginsenoside.

An efficient in vitro protocol has been established for somatic embryogenesis and plantlet conversion of Korean wild ginseng (Panax ginseng Meyer). Wild-type and mutant adventitious roots derived from the ginseng produced calluses on Murashige and Skoog (MS) medium supplemented with 0.5 mg/L 2,4-dichlorophenoxyacetic acid and 0.3 mg/L kinetin; 53.3% of the explants formed callus. Embryogenic callus proliferation and somatic embryo induction occurred on MS medium containing 0.5 mg/L 2,4-dichlorophenoxyacetic acid. The induced somatic embryos further developed to maturity on MS medium with 5 mg/L gibberellic acid, and 85% of them germinated. The germinated embryos were developed to shoots and elongated on MS medium with 5 mg/L gibberellic acid. The shoots developed into plants with well-developed taproots on one-third strength Schenk and Hildebrandt basal medium supplemented with 0.25 mg/L 1-naphthaleneacetic acid. When the plants were transferred to soil, about 30% of the regenerated plants developed into normal plants.

Ko, Byung Woong,Han, Jeongsu,Heo, Jun Young,Jang, Yunseon,Kim, Soo Jeong,Kim, Jungim,Lee, Min Joung,Ryu, Min Jeong,Song, Ik Chan,Jo, Young Suk,Kweon, Gi Ryang Informa UK (Informa Healthcare) 2016 Leukemia & lymphoma Vol.57 No.9

<P>Long-term imatinib treatment induces drug-resistant chronic myeloid leukemia (CML) cells harboring T315I gate keeper mutation of breakpoint cluster region (BCR)-ABL oncogenic kinase. However, although cell proliferation is coupled with cellular energy status in CML carcinogenesis, the metabolic characteristics of T315I-mutant CML cells have never been investigated. Here, we analyzed cell proliferation activities and metabolic phenotypes, including cell proliferation, oxygen consumption, lactate production, and redox state in the KBM5 (imatinib-sensitive) and KBM5-T315I (imatinib-resistant) CML cell lines. Interestingly, KBM5-T315I cells showed decreased cell proliferation, lactate production, fatty acid synthesis, ROS production, and down regulation of mRNA expression related to ROS scavengers, such as SOD2, catalase, GCLm, and GPx1. Taken together, our data demonstrate that the lower growth ability of KBM5-T315I CML cells might be related to the decreased expression of glycolysis-related genes and ROS levels, and this will be used to identify therapeutic targets for imatinib resistance in CML.</P>

Effect of Mixture of Recombinant Human Bone Morphogenic Protein-2 and Demineralized Bone Matrix in Lateral Lumbar Interbody Fusion

Jun Ik Son,Young-Seok Lee,Myeong Jin Ko,Seong-Hyun Wui,Seung Won Park 대한신경외과학회 2024 Journal of Korean neurosurgical society Vol.67 No.3

Objective : This study aims to determine the optimal dose of recombinant-human bone morphogenic protein-2 (rhBMP-2) for successful bone fusion in minimally invasive lateral lumbar interbody fusion (MIS LLIF). Previous studies show that rhBMP is an effective alternative to autologous iliac crest bone graft, but the optimal dose remains uncertain. The study analyzes the fusion rates associated with different rhBMP doses to provide a recommendation for the optimal dose in MIS LLIF. Methods : Ninety-three patients underwent MIS LLIF using demineralized bone matrix (DBM) or a mixture of rhBMP-2 and DBM as fusion material. The group was divided into the following three groups according to the rhBMP-2 usage : group A, only DBM was used (n=27); group B, 1 mg of rhBMP-2 per 5 mL of DBM paste (n=41); and group C, 2 mg of rhBMP-2 per 5 mL of DBM paste (n=25). Demographic data, clinical outcomes, postoperative complication and fusion were assessed. Results : At 12 months post-surgery, the overall fusion rate was 92.3% according to Bridwell fusion grading system. Groups B and C, who received rhBMP-2, had significantly higher fusion rates than group A, who received only DBM. However, there was no significant increase in fusion rate when the rhBMP-2 dosage was increased from group B to group C. The groups B and C showed significant improvement in back pain and Oswestry disability index compared to the group A. The incidence of screw loosening was decreased in groups B and C, but there was no significant difference in the occurrence of other complications. Conclusion : Usage of rhBMP-2 in LLIF surgery leads to early and increased final fusion rates, which can result in faster pain relief and return to daily activities for patients. The benefits of using rhBMP-2 were not significantly different between the groups that received 1 mg/5 mL and 2 mg/5 mL of rhBMP-2. Therefore, it is recommended to use 1 mg of rhBMP-2 with 5 mL of DBM, taking both economic and clinical aspects into consideration.
