GCAM을 이용한 국내 수송부문 모델링

전승호,김수덕 대한교통학회 2017 대한교통학회지 Vol.35 No.2

In this study, we discuss the modeling of domestic transport sector using GCAM(Global Change Assessment Model). The GCAM is one of integrated assessment models widely used in internationally modeling community, and applied for the evaluation of IPCC 5th Report. Nevertheless, it is noted that there are a considerable number of problems in its application to domestic transport sector. First, the base year information of GCAM for detailed transportation service demand is found not consistent with national statistics. Second, the transportation sector simulation results do not properly reflect the past trends of service demand. Thus, the base year service demand is carefully matched with the detailed national statistics. In addition, the existing models were checked and modified so that the simulation results of service demand can accurately reflect past trends of national statistics. As a result, it is reported in detail how the current GCAM simulation results are corrected and how the trend of past transportation sector service demands is properly reflected. This study is expected to be useful as a basic tool for future scenario analysis for transportation policy, technology evaluation and greenhouse gas reduction measures. 본 연구에서는 통합모형인 GCAM을 활용한 국내수송부문을 모델링에 대해 논의한다. GCAM은 IPCC 5차 보고서 평가에도 활용된, 국제적으로 널리 쓰이는 모형이다. 그럼에도 불구하고 이를 국내수송부문에 그대로 적용하는 데 상당한 문제가 있다. 첫째, GCAM의 기준년도(2010년) 수송 서비스수요가 국가통계와 일치하지 않다는 점. 둘째, 수송부문 시뮬레이션 결과가 관련 부문별 서비스수요의 과거추이를 제대로 반영하고 못하고 있다는 점이다. GCAM을 활용한 국내 수송부문 모델링에서 가장 중요하게 영향을 미치는 수송서비스수요 항등식을 상세히 점검함으로써, 기준년도의 서비스수요를 국가통계와 일치시키도록 노력하였다. 또 GCAM의 시뮬레이션 결과가 과거 통계추이를 제대로 반영할 수 있도록 기존모형을 점검, 수정하였다. 점검 및 수정결과, 기존 GCAM의 시뮬레이션 결과와 어떤 부분에서 문제가 있는지, 또 수송부문별 과거 서비스 수요의 추이가 어떻게 제대로 반영되고 있는지를 상세히 보고하였다. 본 연구는 향후 수송부문의 정책, 기술평가 및 온실가스저감 대책 마련 등을 위한 시나리오 분석의 기본분석도구로 유용하게 쓰일 수 있을 것으로 보인다.

Evaluation of Bioactive Compounds in Different Tissues of Sprouting Okra

전승호,노일래,조영손 한국원예학회 2017 Horticulture, Environment, and Biotechnology Vol.58 No.5

The levels of major bioactive compounds, such as amino acids and antioxidants, were investigated in okra sproutsand seeds of the varieties ‘Green Sword’ and ‘Benny’. Total polyphenol content was the highest in ‘Benny’ cotyledons,followed by ‘Benny’ hypocotyls and ‘Green Sword’ cotyledons. Polyphenol and flavonoid content in the two varietieswere approximately 5- to 6-fold higher in sprouts than in seeds, and were higher in the cotyledons than in other tissueswithin the sprout. Activity of the radical scavenger DPPH was the highest in ‘Benny’ cotyledons, and mean valueswere 7.3-fold higher in sprouts than in seeds. Total amino acid content in both varieties was the highest in hypocotyls,followed by cotyledons and seeds. This content was about 40-fold higher in hypocotyls than in seeds. Alanine andGlycyrrhizin were the most abundant amino acids. Total vitamin C content was the highest in ‘Benny’ cotyledons, followedby ‘Green Sword’ cotyledons, and the lowest in hypocotyls of both varieties. In ‘Green Sword’ seeds, the levels ofvitamins B1, B3, B5, and B6 were higher than the levels of B2 and B9. In ‘Benny’, B1 and B3 content were higherin the cotyledon, while B2, B5, and B9 content were higher in the hypocotyl. This study demonstrates the potentialof okra sprouts to be used as a functional food ingredient and as a source of antioxidants.

일임성 식물인 바위솔은 소화의 개화로 고사하는 특성을 가지고 있다. 본 연구는 추대로 형성된 화서의 소화의 개화를 억제하고자 8월 25일부터 매일 암기중단 처리를 가하면서 8월 25일부터 10월 4일까지 2주 간격 (8/25, 9/8, 9/22, 10/4) 으로 총 4회에 걸쳐 화서의 제거시기를 달리 처리하면서 처리 전후의 생장 및 형태 변화를 11월 2일까지 추적하였던 바 그 결과를 요약하면 다음과 같다. 1. 초장, 화서장 및 엽과 포엽수는 화서제거 때까지 급격히 증가하여 화서가 제거된 것과 제거되지 않은 처리간에 차이가 많았으나, 경직경은 처리간 차이가 미미하였다. 2. 9월 하순까지 처리에 의하여 제거되는 화서는 현저히 증가하였으며 잔존하는 엽과 포엽중, 소화중, 지상부중 및 전체 건물중은 초장, 화서장 및 엽과 포엽수와 유사한 반응을 보인 반면, 경중과 근중은 경직경과 유사한 반응을 보였다. 3. 소화는 화서제거 때까지 급격히 증가하였으나 화서제거로 인하여 거의 제거되었다. 화서제거 때까지 형성된 소화는 암기중단 처리로 인하여 개화되지 않았다. 4. 화서제거로 잔존하는 소화가 거의 없기 때문에 화서제거 이후에는 온도관리에 집중되어야 할 것으로 판단되었다. Floret flowering of a monocarpic plant Orostachys japonicus should be controlled to change its harvest time. The study was done to clarify the effect of pinching time of inflorescence with many florets (Aug. 25, Sept. 8 and 22, Oct. 4) on its growth, morphological characters, and flowering. Night-break treatment of 2 hours at midnight were done since Aug. 25 when afterward samples were taken every 2 weeks to Nov. 4. Growth, morphological and flowering related characters were measured from each sample. Plant height, inflorescence length and number of leaves including bracts showed significant difference between the treatments because they were sharply increased until each pinching time. Stem diameter did nearly same. Leaf and bract, floret, shoot and total dry weights had similar response to the plant height, but stem and root dry ones did similar response to the stem diameter. Most florets were removed by the pinching treatments after formed ones were increased until each pinching time. Few florets were left after the treatment, meaning that night-break treatment after that could be skipped.

This study was conducted to elucidate the effect of organic fertilizer on growth characteristics, saponin contents and antioxident activity of Platycodin grandiflorum Ridix roots for organic farming. As basal fertilizers, chemical fertilizer, mixed organic fertilizer, bacterial cultures and fermented oil cake and decomposed manure were treated based on 3 ㎏/10a level before transplanting Platycodin grandiflorum Ridix. In root length, when chemical fertilizer plot and mixed organic fertilizer plot were treated, root length was recorded the highest scores (25.3 and 24.0 ㎝) Root width was recorded the highest score (26.6 ㎝) in chemical fertilizer plot. The number of fine-roots was the highest in mixed organic fertilizer plot and chemical fertilizer plot (20.0 and 17.0), respectively. Fresh weight, which affects directly yield, was the highest in organic fertilizer plot (55.7 g/plant). The content of Platycodin D was shown to 327.4~373.8 ㎎/100 g, the highest values were observed in organic fertilizer plot. The total polyphenol and flavonoid contents were recorded the highest scores (15.5 and 15.3 mg/g, respectively) in organic fertilizer plot. In this study we confirmed that application of organic fertilizer was effective to increase yield and pharmacological effect through increase of the number of fine-roots with high saponin contents.

클라우드 기반의 악성 IP 탐지를 위한 보안 시스템 구축 연구

전승호,권오준,박원형 국방보안연구소 2021 국방과 보안 Vol.3 No.2

Recently, cyber threats related to malicious code are increasing, and unlike large enterprises with well-established security systems, small and medium-sized enterprises (SMEs) or organizations that require a security system are vulnerable to cyber threats. In order to establish a security system against malicious behaviors with low cost for security, this paper proposes a system for detecting and blocking malicious IPs using Malware API. Reliable Malware API is used to distinguish between normal IP and malicious IP. It creates a database of malicious IPs through IPs identified based on the Malware API, sets access control based on security indicators, and provides notification functions to security administrators to facilitate identification of malicious IPs. This system can efficiently respond to infringement incidents by detecting and blocking malicious IPs in the cloud-based security system in a vulnerable environment from the system serviced through the server.

This study was conducted to elucidate the effects of green manure crop on growth characteristics and saponin contents of Platycodin grandiflorum Ridix roots for organic farming. Rye, hairy vetch and rye+hairy vetch were cultivated as green manure crops with several different methods before transplanting P. grandiflorum Radix. In root width and number of fine-roots, when the highest scores (23.9 mm, 25.7) was recorded in rye pre-cultibated plot in $2^{nd}$ year cultivation. Fresh weight of the Platycodin grandiflorum Ridix root was no significant difference among the different green manure crop treatments, but fresh weights of the Platycodin grandiflorum Ridix root of all green manure crop treatments were higher than that of control. The total content of saponin was highest detected in Platycodin grandiflorum Ridix roots of the hairy vetch plot (1,106 mg/100 g) and rye plot (1,693 mg/100 g) in $1^{st}$ and $2^{nd}$ year cultivation, respectively. Therefore, we confirmed that precultivation of the green manure crops showed significant differences in the growth characteristics and saponin contents of the Platycodin grandiflorum Ridix root, and growth and saponin contents in the Platycodin grandiflorum Ridix root of rye precultivated plot was much higher in $2^{nd}$ year cultivation than $1^{st}$ year cultivation. 이 연구는 도라지의 유기재배를 위하여 3년근 이식 예정지에 풋거름 작물 재배에 따른 도라지 뿌리의 생육특성 및 사포닌 함량에 미치는 영향을 구명하고자 실시되었다. 생육특성에서는 기재배지에서의 뿌리의 직경 및 곁뿌리 수는 호밀 재배구에서 가장 굵거나 많았으며, 뿌리 생체중은 풋거름작물 재배구간 차이는 없었으나, 대조구에 비해 높게 나타났다. 도라지 뿌리의 무기성분 함량에서는 무기성분별 유의성이 있는 것으로 나타났으며 특히, 기재배지에서의 호밀 처리구에서 높은 함량이 나타났다. 사포닌 함량의 변화에서는 기재배지에서는 호밀 재배구에서 모든 사포닌 함량이 가장 높은 함량으로 나타났으며, 새재배지에서는 헤어리베치 재배구에서 높은 함량을 나타냈다. 대조구에 비해 풋거름작물 재배구의 기재배지와 새재배지 모든 재배구에서 사포닌의 함량이 높게 나타났다. 따라서 도라지 유기재배 시 풋거름작물에 따른 뿌리의 생육 특성 및 약리성의 변화 등의 유의적인 차이가 나타나는 것을 확인할 수 있었으며, 연차 간 재배 시 호밀 재배구에 생육 및 약리성이 우수한 것으로 나타났다.
