Recently a construction industry introduces information that brings about many advantages in the early planning phase, design phase and construction phase. Especially it replaces 2D, 3D systems(usually using explanation of drawing information) as 4D CAD(offering a sort of 4D-having relation of construction schedule and 3D drawing information). Nevertheless a 4D has these benefits, it has limits which are not only usually using 3D modeling but also limit of making full use of practical affairs because of a lack of connecting varietals of progress of work. To solve these uppermost limits, this research is presenting unified systems to use in risk management which are efficient management of space and non-space information, space analysis, making full use of data base, introducing GIS system of easy interaction.

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.

전승호,손다니엘,류영섭,김석현,정종일,김민철,심상인 한국약용작물학회 2010 한국약용작물학회지 Vol.18 No.1

Several presowing seed treatments have been used to facilitate the seed germination and seedling emergence. The study was performed to design a model of presowing seed treatments in Taraxacum platycarpum. Germination and seedling growth responses to temperature, drying, chilling, GA3 and priming were investigated to know the optimum germination conditions and presowing treatment. The optimum temperature condition for germination and seedling growth were 15~20℃ at dark condition. The seeds exposed to infra red light, however, did not germinate. The moisture content of seeds dried at 35℃ for 3.5 hours was returned to the level of unimbibed seeds. The germination of seeds dried under dark condition was better than those dried under infra red light. Prechilling treatment imposed for 6 weeks showed higher germination rate than GA3 treatment or priming. In field test, the highest field emergence was observed in the seeds dried after prechilled for 6 weeks and followed by drying followed by GA3 〉 low temperature 〉 KNO3 priming. Imbibition with 0.1 mM GA3 solution for 2 hours then drying at 35 for 3.5 hour under dark condition was effective to the practical presowing treatment for Taraxacum seeds.

화서제거 시기가 바위솔의 생장과 개화에 미치는 영향

전승호,이창우,김홍영,신성철,강진호 韓國藥用作物學會 2007 한국약용작물학회지 Vol.15 No.4

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.

전승호,이경민,윤간우,백도명,유종엽,은희철 大韓産業醫學會 2003 대한직업환경의학회지 Vol.15 No.3

목적: 정유공장의 폴리프로필렌(polypropylene) 부서와 복합수지 부서에서 사용되는 첨가제들중 피부첩포검사를 통하여 피부독성을 야기할 수 있는 물질들을 알아보기 위해서 본 조사를 수행하였다. 방법: 일개 정유공장에서 총 44명의 근로자를 대상으로 폴리프로필렌공정에서 첨가제를 취급한 노출군과 그런 작업을 하지 않은 비노출군으로 나누어 피부첩포검사를 했다. 노출군은 27명으로 과거 노출자 10명, 현노출자 17명이었다. 비노출군은 17명이었다. 10개의 첨가물 중 Microstat 16은 0.25%, Amoslip-CP는 0.1%의 농도로 첩포검사를 하고, 나머지 8종은 1%의 농도에서 검사 후 48시간 후 피부에 양성반응을 보이면 0.1%로다시 피부첩포검사를 했으며 음성방응을 보이면 10%로 검사를 시행했다. 결과: 각 물질별 결과로는 Ultranox-626과 Millad 3988이 가장 많은 피부양성반응을 보였다. 피부의 발진을 많이 보이는 (양성 및 의양성) 빈도는 Ultranox-626, Millad 3988, Armoslip-E, Songstab Sc-100 순이었다. 피부에 발진을 보이는 (양성 및 의양성) 대상자는 18명(41%)이었고, 그중 노출군이 14명(51.9%)이고 비노출군이 4명(23.5%)으로누출군에서 더 많은 발진을 야기하였다. 피부첩포검사에서 반응을 보이는 18명 중 자극가증서응로 작용하는 대상자는 7명(38.9%)이었고, 알레으기 가능성으로 작용하는 대상자는 6명(33.3%)이었으며 여러 물질에 강한 반응을 보이는 다중 반응 대상자는 5명(27.8%)이었다. 알레르기 가능성 반응 대상자는 현재의 노출자가 과거노출자와 비노출자 보다 통계적으로 유의하게 많았다(p=0.04). 자극가능성 반응 대상자들 중 현재 노출자, 과거노출자, 비노출자 사이의 통계적 차이는 없었다. 다중 반응 대상자는 과거노출자가 통계적으로 유의하게 많았고(p=0.05), 현재의 노출자는 없었다. 결론: 자극성 반응과 알레르기성 반응을 포함하여 첨가제에 노출된 집단이 비노출군보다 높은 과민상태를 보였다. 결과적으로 이들 물질에 노출되는 경우 잠재적 알레으기 가능성 반응이 유발 될 수 있능 것으로 보인다. 피부첩포검사에서 반응을 보이는 원인물질로 빈도가 높은 Ultranox-626 Millad 3988 Armoslip-E Songstab Sc-100의 4가지 물질에 대한 노출을 우선적으로 관리하는 것이 필요하다고 판단된다. 첨가물의 알레으기 여부를 정확히 판정하는 작업과 피부병 유발 가능성을 향후 좀더 구명할 필요가 있을 것으로 보인다. Objects: To investigate the causative agents for the dermatological problems associated with the polypropylene manufacturing process. Methods: The study subjects consisted of 44 male workers involved in the polypropylene manufacturing process. Twenty-seven of them had been exposed to additives, and the remaining 17 had not. Among the 27 exposed, 10 had been exposed previously, and 17 are currently being exposed through their duties. Patch test were performed with three different concentrations, 0.1%, 1% and 10% of 10 different additives that was diluted with Vaseline. Results: 18 subjects (41%) had positive reactions to the patch tests. Exposed group had a higher reaction rate (51.9%) than the control group (23.5%). When the positive reactions were further classified, 7, 6 and 5 were compatible with probablu irritant, probably allergic, and multiple hypersensitivity reactions respectively. The most frequent reactions were from Ultranox-626 followed by Millad 3988, Armoslip-E and Songstab Sc-100. Conclusions: When considering the significantly higher probability of an allergic reaction rate among the currently exposed group compared to non- or previously-exposed groups, the nature of dermatological problems in a polypropylene plant is probably allergic. Ultranox-626, Millad3988, Armoslip-E and Songstab Sc-100 were the main causatives agents found in the process.

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.
