Using GOES-R ABI Full-Disk Reflectance as a Calibration Source for the GOES Imager Visible Channels
Authors: Heidinger Andrew K. , Foster Michael J. , Knapp Kenneth R. , Schmit Timothy J.
Published: August 2022

The availability of onboard calibration for solar reflectance channels on recently launched advanced geostationary imagers provides an opportunity to revisit the calibration of the visible channels on past geostationary imagers, which lacked onboard calibration systems. This study used the data from the Advanced Baseline Imager (ABI) on GOES-16 and GOES-17 to calibrate the visible channels on the GOES-IP (GOES-8, -9, -10, -11, -12, -13, and -15) sensors (1994–2021). The visible channels are dominant sources of information for many of the essential climate variables from these sensors. The technique developed uses the stability of the integrated full-disk reflectance to define a calibration target that is applied to past sensors to generate new calibration equations. These equations are found to be stable and agree well with other established techniques. Given the lack of assumptions and ease of application, this technique offers a new calibration method that can be used to complement existing techniques used by the operational space agencies with the GSICS Project. In addition, its simplicity allows for its application to data that existed prior to many of the reference data employed in current calibration methods.

Published: August 2022

Industrial activities induce various impacts on ecosystems that influence species richness and distribution. An effective way to assess the resulting impacts on biodiversity lies in vegetation mapping. Species classification achieved through supervised machine learning algorithms at the pixel level has shown promising results using hyperspectral images and multispectral, multitemporal images. This study aims to determine whether airborne hyperspectral images with a high spatial resolution or phenological information obtained by spaceborne multispectral time series (Sentinel-2) are suitable to discriminate species and assess biodiversity in a complex impacted context. The industrial heritage of the study site has indeed induced high spatial heterogeneity in terms of stressors and species over a reduced scale. First, vegetation indices, derivative spectra, continuum removed spectra, and components provided by three feature extraction techniques, namely, Principal Component Analysis, Minimal Noise Fraction, and Independent Component Analysis, were calculated from reflectance spectra. These features were then analyzed through Sequential Floating Feature Selection. Supervised classification was finally performed using various machine learning algorithms (Random Forest, Support Vector Machines, and Regularized Logistic Regression) considering a probability-based rejection approach. Biodiversity metrics were derived from resulted maps and analyzed considering the impacts. Average Overall Accuracy (AOA) reached up to 94% using the hyperspectral image and Regularized Logistic Regression algorithm, whereas the time series of multispectral images never exceeded 72% AOA. From all tested spectral transformations, only vegetation indices applied to the time series of multispectral images increased the performance. The results obtained with the hyperspectral image degraded to the specifications of Sentinel-2 emphasize the importance of fine spatial and spectral resolutions to achieve accurate mapping in this complex context. While no significant difference was found between impacted and reference sites through biodiversity metrics, vegetation mapping highlighted some differences in species distribution.

Published: August 2022

In order to study and forecast extreme weather, a comprehensive and systematic analysis of the spatial and temporal relationship between Precipitable Water Vapor (PWV), predicted by Numerical Weather Predication (NWP) data, and precipitation, is necessary. The goal of this paper was to study the temporal and spatial relationship between PWV and precipitation during the so-called ‘July 20’ (18–21 July 2021) heavy rainstorm in Zhengzhou. Firstly, the PWV data provided by 120 radiosonde stations uniformly distributed throughout the world, and two IGS stations in China, in 2020, was used to evaluate the accuracy of PWV estimation by ERA5 and MERRA-2 data, and the factors affecting the accuracy of NWP PWV were explored. Secondly, ERA5 PWV and the precipitation data of six meteorological stations were used to qualitatively analyze the relationship between PWV and precipitation during the ‘July 20’ heavy rainstorm in Zhengzhou. Finally, a quantitative study was conducted by an eigenvalue matching method. The main experimental results were as follows. Compared with MERRA-2 PWV, the accuracy of ERA5 PWV was slightly higher. Latitude, altitude and season were the influencing factors of the NWP PWV estimation accuracy. The change trend of ERA5 PWV was consistent with both 24 h cumulative precipitation and surface precipitation during the ‘July 20’ heavy rainstorm in Zhengzhou. The average optimal matching degree and optimal matching time between NWP PWV and surface precipitation during the ‘July 20’ heavy rainstorm in Zhengzhou was 56.6% and 3.68 h, respectively. The maximum optimal matching degree was 80.3%. The spatial–temporal relationship between NWP PWV and surface precipitation was strong.
Detection of Flash Flood Inundated Areas Using Relative Difference in NDVI from Sentinel-2 Images: A Case Study of the August 2020 Event in Charikar, Afghanistan
Authors: Atefi Mujeeb Rahman , Miura Hiroyuki
Published: August 2022

On 26 August 2020, a devastating flash flood struck Charikar city, Parwan province, Afghanistan, causing building damage and killing hundreds of people. Rapid identification and frequent mapping of the flood-affected area are essential for post-disaster support and rapid response. In this study, we used Google Earth Engine to evaluate the performance of automatic detection of flood-inundated areas by using the spectral index technique based on the relative difference in the Normalized Difference Vegetation Index (rdNDVI) between pre- and post-event Sentinel-2 images. We found that rdNDVI was effective in detecting the land cover change from a flash flood event in a semi-arid region in Afghanistan and in providing a reasonable inundation map. The result of the rdNDVI-based flood detection was compared and assessed by visual interpretation of changes in the satellite images. The overall accuracy obtained from the confusion matrix was 88%, and the kappa coefficient was 0.75, indicating that the methodology is recommendable for rapid assessment and mapping of future flash flood events. We also evaluated the NDVIs’ changes over the course of two years after the event to monitor the recovery process of the affected area. Finally, we performed a digital elevation model-based flow simulation to discuss the applicability of the simulation in identifying hazardous areas for future flood events.
Estimation and Simulation of Forest Carbon Stock in Northeast China Forestry Based on Future Climate Change and LUCC
Authors: Sun Jianfeng , Zhang Ying , Qin Weishan , Chai Guoqi
Published: August 2022

Forest carbon sinks (FCS) play an important role in mitigating global climate change, but there is a lack of more accurate, comprehensive, and efficient forest carbon stock estimates and projections for larger regions. By combining 1980–2020 land use data from the Northeast China Forestry (NCF) and climate change data under the Shared Socioeconomic Pathway (SSP), the land use and cover change (LUCC) of NCF in 2030 and 2050 and the FCS of NCF were estimated based on the measured data of forest carbon density. In general, the forest area of NCF has not yet recovered to the level of 1980. The temporal change in the FCS experienced a U-shaped trend of sharp decline to slow increase, with the inflection point occurring in 2010. If strict ecological conservation measures are implemented, the FCS of the NCF is expected to recover to the 1980 levels by 2050. We believe that the ecological priority (EP) scenario is the most likely and suitable direction for future development of the NCF. We also advocate for more scientific and stringent management measures for NCF natural forests to unlock the huge potential for forest carbon sequestration, which is important for China to meet its carbon neutrality commitments.
On Characteristics and Mixing Effects of Internal Solitary Waves in the Northern Yellow Sea as Revealed by Satellite and In Situ Observations
Authors: Liu Heping , Yang Wei , Wei Hao , Jiang Chengfei , Liu Changgen , Zhao Liang
Published: August 2022

This study examines the characteristics, statistics, and mixing effects of internal solitary waves (ISWs) observed in the northern Yellow Sea (YS) during the summers of 2018 and 2019. The mooring stations are located between offshore islands with rough topographic features. Throughout the observation period, the ISWs with vertical displacements of up to 10 m induced prevailing high-frequency (3–10 min period) temperature variations. Synthetic aperture radar (SAR) images showed that the observed ISWs propagate in zonal directions generated around the islands where internal-tide-generating body force is strong. The estimated ISW propagation speed ranges from 0.16 to 0.25 m s−1, which agrees with the Korteweg-de Vries (KdV) model. The ISW intensity exhibits a clear spring-neap cycle corresponding to the local tidal forcing. The constant occurrence of ISWs at low tide suggests an important generation site where the ISWs are tidally generated. The ray-tracing result indicates that this generation site appears to be located at a strait between Dahao and Xiaohao islands. A generalized KdV model successively reproduces the propagation process from the generation site to the mooring station. Following the passage of ISWs, microstructure profiling observations reveal a high turbulent kinetic energy dissipation rate (10−6 W kg−1). The prevalence of ISWs in the study area is believed to play a crucial role in regulating vertical heat and nutrient transport, thereby modulating the biogeochemical cycle.

Published: August 2022

Dust storms are common in Mongolia and northern China, this is a serious threat to the ecological security and socioeconomic development of both countries and the surrounding areas. However, a complete quantitative study of the source area, affected area, and moving path of dust storm events (DSEs) in Mongolia and China is still lacking. In this study, we monitored and analyzed the spatiotemporal characteristics of the source area and affected areas of DSEs in Mongolia and China using the high-spatiotemporal-resolution images taken by the Himawari-8 satellite from March to June 2016–2020. In addition, we calculated the moving path of dusty weather using the HYSPLIT model. The results show that (1) temporality, a total of 605 DSEs occurred in the study area, with most of them occurring in April (232 DSEs), followed by May (173 DSEs). Spatially, the dust storm sources were concentrated in the arid inland areas such as the Taklimakan Desert (TK, 138 DSEs) and Badain Jaran Desert (BJ, 87 DSEs) in the western, and the Mongolian Gobi Desert (GD, 69 DSEs) in the central parts of the study area. (2) From the affected areas of the DSEs, about 60% of the DSEs in Mongolia started locally and then affected downwind China, as approximately 55% of the DSEs in the Inner Mongolia Desert Steppe and Hunshandake Sandy Land came from Mongolia. However, the DSEs in the TK located in the Tarim Basin of northwest China affected the entire study area, with only 31.3% belonging to the local dust. (3) From the moving path of the dusty weather, the dusty weather at the three meteorological stations (Dalanzadgad, Erlian, and Beijing), all located on the main transmission path of DSEs, was mainly transported from the windward area in the northwest, accounting for about 65.5% of the total path. This study provides a reliable scientific basis for disaster prevention and control, and has practical significance for protecting and improving human settlements.

This study examines uncertainties in the retrieval of the Aerosol Optical Depth (AOD) for different aerosol types, which are obtained from different satellite-borne aerosol retrieval products over North Africa, California, Germany, and India and Pakistan in the years 2007–2019. In particular, we compared the aerosol types reported as part of the AOD retrieval from MODIS/MAIAC and CALIOP, with the latter reporting richer aerosol types than the former, and from the Ozone Monitoring Instrument (OMI) and MODIS Deep Blue (DB), which retrieve aerosol products at a lower spatial resolution than MODIS/MAIAC. Whereas MODIS and OMI provide aerosol products nearly every day over of the study areas, CALIOP has only a limited surface footprint, which limits using its data products together with aerosol products from other platforms for, e.g., estimation of surface particulate matter (PM) concentrations. In general, CALIOP and MAIAC AOD showed good agreement with the AERONET AOD (r: 0.708, 0.883; RMSE: 0.317, 0.123, respectively), but both CALIOP and MAIAC AOD retrievals were overestimated (36–57%) with respect to the AERONET AOD. The aerosol type reported by CALIOP (an active sensor) and by MODIS/MAIAC (a passive sensor) were examined against aerosol types derived from a combination of satellite data products retrieved by MODIS/DB (Angstrom Exponent, AE) and OMI (Aerosols Index, AI, the aerosol absorption at the UV band). Together, the OMI-DB (AI-AE) classification, which has wide spatiotemporal cover, unlike aerosol types reported by CALIOP or derived from AERONET measurements, was examined as auxiliary data for a better interpretation of the MAIAC aerosol type classification. Our results suggest that the systematic differences we found between CALIOP and MODIS/MAIAC AOD were closely related to the reported aerosol types. Hence, accounting for the aerosol type may be useful when predicting surface PM and may allow for the improved quantification of the broader environmental impacts of aerosols, including on air pollution and haze, visibility, climate change and radiative forcing, and human health.
Few Shot Object Detection for SAR Images via Feature Enhancement and Dynamic Relationship Modeling
Authors: Chen Shiqi , Zhang Jun , Zhan Ronghui , Zhu Rongqiang , Wang Wei
Published: August 2022

Current Synthetic Aperture Radar (SAR) image object detection methods require huge amounts of annotated data and can only detect the categories that appears in the training set. Due to the lack of training samples in the real applications, the performance decreases sharply on rare categories, which largely inhibits the detection model from reaching robustness. To tackle this problem, a novel few-shot SAR object detection framework is proposed, which is built upon the meta-learning architecture and aims at detecting objects of unseen classes given only a few annotated examples. Observing the quality of support features determines the performance of the few-shot object detection task, we propose an attention mechanism to highlight class-specific features while softening the irrelevant background information. Considering the variation between different support images, we also employ a support-guided module to enhance query features, thus generating high-qualified proposals more relevant to support images. To further exploit the relevance between support and query images, which is ignored in single class representation, a dynamic relationship learning paradigm is designed via constructing a graph convolutional network and imposing orthogonality constraint in hidden feature space, which both make features from the same category more closer and those from different classes more separable. Comprehensive experiments have been completed on the self-constructed SAR multi-class object detection dataset, which demonstrate the effectiveness of our few-shot object detection framework in learning more generalized features to both enhance the performance on novel classes and maintain the performance on base classes.

Published: August 2022

In order to promote the economic development of China’s provinces and provide references for the provinces to make effective economic decisions, it is urgent to investigate the trend of province-level economic development. In this study, DMSP/OLS data and NPP/VIIRS data were used to predict economic development. Based on the GDP data of China’s provinces from 1992 to 2016 and the nighttime light remote sensing (NTL) data of corresponding years, we forecast GDP via the linear model (LR model), ARIMA model, ARIMAX model, and SARIMA model. Models were verified against the GDP records from 2017 to 2019. The experimental results showed that the involvement of NTL as exogenous variables led to improved GDP prediction.
The Robust Multi-Scale Deep-SVDD Model for Anomaly Online Detection of Rolling Bearings
Authors: Kou Linlin , Chen Jiaxian , Qin Yong , Mao Wentao
Published: August 2022

Aiming at the online detection problem of rolling bearings, the limited amount of target bearing data leads to insufficient model in training and feature representation. It is difficult for the online detection model to construct an accurate decision boundary. To solve the problem, a multi-scale robust anomaly detection method based on data enhancement technology is proposed in this paper. Firstly, the training data are transformed into multiple subspaces through the data enhancement technology. Then, a prototype clustering method is introduced to enhance the robustness of features representation under the framework of the robust deep auto-encoding algorithm. Finally, the robust multi-scale Deep-SVDD hyper sphere model is constructed to achieve online detection of abnormal state data. Experiments are conducted on the IEEE PHM Challenge 2012 bearing data set and XJTU-TU data set. The proposed method shows much greater susceptibility to incipient faults, and it has fewer false alarms. The robust multi-scale Deep-SVDD hyper sphere model significantly improves the performance of incipient fault detection for rolling bearings.

Published: August 2022

A expansão de atividades ecoturísticas nos espaços rurais brasileiros é uma alternativa para o desenvolvimento sustentável. A caminhada por trilhas ecológicas é uma prática ecoturística que propicia o contato com o meio e a sensibilização dos visitantes em áreas de conservação públicas e privadas. O planejamento adequado das trilhas ecológicas é importante para mitigar os impactos decorrentes da sua instalação e uso, bem como garantir a segurança dos usuários. Nesse contexto, foi realizado um estudo de caso no Rancho Sol Dourado, uma propriedade particular situada em Macaé de Cima, zona rural de Nova Friburgo-RJ e  inserida em Unidades de Conservação (UCs): o Parque Estadual dos Três Picos (PETP) e a Área de Proteção Ambiental (APA) de Macaé de Cima. O estudo teve como objetivo principal planejar trilhas ecológicas na propriedade, conciliando a conservação ambiental e a expansão da atividade ecoturística local. As atividades consistiram em percorrer picada e caminhos já abertos, realizar medições da extensão e largura do leito, observar características, como a presença de vegetação nas bordas, sinais de erosão, entre outros aspectos do Protocolo de Avaliação Rápida para Trilhas de Montanha (PAR-TM), e sinalizar pontos críticos para intervenções, considerando a conservação e o equilíbrio ambiental. Foram propostas adequações para o uso dos caminhos e picada como trilhas ecológicas, resultando em três trilhas com características distintas: a Trilha da Mata, a Trilha do São Caetano e a Trilha dos Balanços. A primeira, considerada de maior grau de dificuldade, demandou maior número e complexidade de intervenções. A segunda, considerada a mais inclusiva, exigiu intervenções de menor complexidade. A terceira, mais curta, de dificuldade moderada, demandou intervenções em grau mediano. Por fim, o sistema de trilhas planejado foi composto por trilhas diversificadas, na motivação para percorrê-las, no grau de dificuldade e no público-alvo.

Published: August 2022

As parcerias para o turismo em Unidades de Conservação  constituem uma estratégia para a implementação de políticas públicas de conservação da natureza. Considerando o contexto no qual as parcerias são implementadas, em um plano global, implicadas pelos desdobramentos do neoliberalismo nas políticas públicas ambientais e, em específico, pelos diversos interesses dos atores sociais em jogo, é fundamental o acompanhamento das práticas de controle social e dos efeitos na gestão do patrimônio natural e cultural e no desenvolvimento do território. O presente trabalho tem por objetivo analisar a participação social no processo de concessão dos serviços de apoio à visitação no Parque Estadual do Ibitipoca (PEIb - MG), à luz da responsabilização pelo controle social. Para tanto, a pesquisa, de caráter qualitativo e exploratório, envolveu a realização de levantamento bibliográfico e documental envolvendo o processo de concessão no PEIb, bem como a observação não participante em audiência pública. A análise dos dados, guiada por valores públicos como a responsabilização pelo controle social, demonstra que: a concessão dos serviços de apoio à visitação no PEIb é apresentada à sociedade sem que esta tivesse a oportunidade de construção desde a concepção ou planejamento da modalidade de parceria em questão; a modelagem da concessão apresenta aspectos limitados no que se refere à inclusão social e à redução de desigualdades sociais; e foram acionados diferentes mecanismos de controle social no sentido de interromper ou redirecionar o processo para uma construção colaborativa e democrática, visando a melhoria da qualidade de vida, o desenvolvimento do território e a conservação do patrimônio natural e cultural. A participação social e o acionamento de mecanismos de controle social sobre as concessões em Unidades de Conservação  podem ser uma medida para avaliar o exercício da democracia na implementação de políticas públicas e na apropriação das áreas protegidas como um bem público.

Este artigo tem por objetivo refletir sobre a temática Educação Ambiental (EA) e licenciamento ambiental (LA), a partir dos trabalhos apresentados no Encontro Pesquisa em Educação Ambiental (EPEA) entre os anos de 2001 e 2019. Realizamos esse modesto estado da arte por meio da busca no site dos anais do EPEA de artigos ligados a essa temática e utilizamos a proposta da análise de conteúdo de Laurence Bardin. Constatamos que, foi possível identificar 3 categorias: crítico, conflitos e consensos, e que a macrotendência da EA crítica é hegemônica nessas pesquisas em diálogo com a questão dos conflitos ambientais, porém ambas inconscientemente acabam ficando reféns das decisões das instituições solicitantes dos licenciamentos ambientais.

3D photoacoustic computed tomography (3D-PACT) has made great advances in volumetric imaging of biological tissues, with high spatial-temporal resolutions and large penetration depth. The development of 3D-PACT requires high-performance acoustic sensors with a small size, large detection bandwidth, and high sensitivity. In this work, we present a new high-frequency 3D-PACT system that uses a microring resonator (MRR) as the acoustic sensor. The MRR sensor has a size of 80 
μ
m in diameter and was fabricated using the nanoimprint lithography technology. Using the MRR sensor, we have developed a transmission-mode 3D-PACT system that has achieved a detection bandwidth of ~23 MHz, an imaging depth of ~8 mm, a lateral resolution of 114 
μ
m, and an axial resolution of 57 
μ
m. We have demonstrated the 3D PACT’s performance on
in vitro
phantoms,
ex vivo
mouse brain, and
in vivo
mouse ear and tadpole. The MRR-based 3D-PACT system can be a promising tool for structural, functional, and molecular imaging of biological tissues at depths.

Published: August 2022

Background. Inferior alveolar nerve damage can lead to mild to severe paresthesia and even facial pain. One of the treatments considered today for the reconstruction and treatment of damaged peripheral nerves is the use of vitamin supplements. This study aimed to evaluate the effect of vitamin B complex supplementation on pain and sensory problems following mandibular implant placement surgery. Methods. In this single-blind clinical trial, 46 patients applying for implant placement, who were eligible for the study, were evaluated. All the patients were examined for sensory facial injury and inferior alveolar nerve injury within 24 hours after implant placement. The nerve damage was recorded by AI (asymmetry index) in the initial examination. Patients who reported clinical and radiographic signs of nerve damage due to implant or drill impingement of the nerve canal were excluded from the study and promptly treated with anti-inflammatory protocols. Then the patients were randomly divided into control (n=23) and intervention (n=23) groups. Patients in the control group received routine treatment after implantation, and patients in the intervention group received vitamin B complex pills in addition to routine treatment. A placebo was used to eliminate the inductive effect of the drug in the control group. Follow-up of patients was performed at intervals of 14 days and 1, 2, and 3 months after treatment. Data analysis was performed using SPSS 24 and Kruskal-Wallis, Wilcoxon, and chi-squared tests. Results. In both groups, a decreasing trend in pain intensity was observed for up to three months. There were no significant differences between the mean pain intensity in the intervention and control groups at all the follow-up intervals. In both groups, a decrease in the rate of paresthesia was observed during the 3-month follow-up. The mean of paresthesia in the two groups was not significantly different at any follow-up interval. Conclusion. Vitamin B complex might not affect pain intensity and paresthesia after implant surgery.

Published: August 2022

Because of the low impurity removal rate and high damage rate of the potato combine harvester during the working process, a new type of impurity removal device for the potato combine harvester was designed. The device was mainly composed of retaining plates, impurity removal rollers, smooth rollers, and a control system. To determine the best working parameters of the device, the rotational speed of the rollers, the distance between two rollers, and the inclination angle of the device were used as the test factors. The impurity removal rate and damage rate were employed as the evaluation indexes. Then, the single factor test and the second rotation orthogonal regression test were performed. The optimum combination after parameter optimization was determined to be as follows: rotational speed of the rollers was 113.4 r/min, the distance between the two rollers was 97.5 mm and the inclination angle of the device was 10.4°. The corresponding impurity removal rate was 95.12%, and the damage rate was 0.54%. The device can better meet the requirements of impurity removal operations.

Doğası gereği yapılı çevre insanları kendi üç boyutlu boşluğuna sokar ve bu nedenle onlara özel ve üç boyutlu estetik deneyimler sağlar. Bu deneyimler, bilinen görsel sanat eserlerini deneyimlemekten farklıdır. İki boyutlu analog mimari sunumlar, mimari mekan hakkında bu tür deneyimler sağlayamaz. Bu deneyimler, üç boyutlu olmamasından ötürü, mimari boşluğu bilgisayar ekranı aracılığı ile sunan Sanal Gerçeklik (VR) ile de elde edilemez. Üç boyutlu sanal gerçeklik (IVR), izleyiciyi dış dünyadan ayıran ve onu sanal ekrana çeken CAVE ve Başa Takılan Ekran (HMD) gibi özel yazılım ve donanımlar, üç boyutlu ortam deneyimi sağlamanın bir yolu olarak ortaya çıkmıştır. Özellikle mimari tasarımda yeni tasarlanacak projeleri araştırmak için kullanılmıştır. Mevcut binaları keşfetmek için IVR kullanımı çok yaygın değildir. İnşa edilmiş ve inşa edilmemiş mimari projelerin estetik niteliklerini değerlendirmede IVR'nin kullanımı ise nadiren yaygındır. Mimari eğitimde IVR kullanımı, hem öğrencilere bina ve tasarım çalışmaları için üç boyutlu deneyimler sunmak üzere yaygın değildir hem de öğrenciler tarafından çalışmalarını stüdyolarda sunmak için kullanılmaz. Bu araştırma, mimari estetiğin değerlendirilmesinde IVR'nin kullanımını inceleyen birkaç örnekten biridir. Bu çalışmada Bahreyn Üniversitesi Mimarlık ve İç Mekan Tasarımı Bölümü'nde gerçekleştirilen bir ders kapsamında bir grup kız öğrenciye, çevresel estetik üzerine IVR'yi tanıtan bir deney sunulmuştur. Öğrenciler, hem IVR hem de binanın fotoğraflarını kullanarak gerçek bir binanın mimari estetiğini karşılaştırmalı olarak değerlendirmişlerdir. Fotoğraflara kıyasla IVR'nin, öğrencilerin binanın mimari estetiği hakkındaki değerlendirmelerini önemli ölçüde geliştirdiği keşfedilmiştir. Ayrıca öğrencilerin IVR hakkında çok az bilgiye sahip oldukları ve IVR’yi etkin bir mimari eğitim aracı olarak kullanmaktan yana oldukları tespit edilmiştir.

The exposure of sunlight consisting UV radiation has been reported to be the main cause of skin cancer and contribute about 80% of the incidence of skin damage. In an attempt to overcome this problem, antioxidant agents have been used both orally and topically. Compared to oral administration, topical route has been found to be preferred due to the direct action to the desired site. Amongst topical preparation, gel possesses numerous because it provides a cool and fresh sensation. Here, we developed gel antioxidant containing cinnamon extract as active ingredient. Cinnamon was selected as it has a very strong antioxidant activity. This study aimed to obtain the penetration profile of the antioxidant gel of cinnamon extract prepared from two different hydrocolloid agents. The gels were made using various concentrations of Carbopol 940 and NaCMC. The prepared gels were further characterized for their antioxidant capacities using the DPPH free radical scavenging method and their total phenolic contents using the spectrophotometric method. The formulation possessing the strongest antioxidant capacity was continued for ex vivo penetration study using Franz diffusion cells. The results exhibited that the total phenolic value of the cinnamon extract obtained was 908.38 ± 6.54 mg GAE/g extract. The penetration percentages for the formula with Carbopol and NaCMC bases were 53.310 ± 1.217% and 27.969 ± 1.151%, respectively, and the retention percentages were 28.495 ± 0.031% and 18.356 ± 0.191%, respectively. Based on these findings, we concluded that cinnamon extract could potentially be formulated into antioxidant gel preparations and formulas based on Carbopol showed the best penetration profile.

Hiperkolesterolemia yang ditandai dengan meningkatnya kadar kolesterol total >200 mg/dL. Hiperkolesterolemia dapat meningkatkan risiko terjadinya aterosklerosis yang merupakan penyebab utama Penyakit Jantung Koroner (PJK). Indeks Aterogenik Plasma (IAP) dan Indeks Risiko Koroner (IRK) merupakan parameter yang baik untuk melihat risiko terjadinya aterosklerosis dan PJK. Virgin Coconut Oil (VCO) telah diketahui memiliki potensi antikolesterol. Tujuan dari penelitian ini mengetahui pengaruh pemberian VCO terhadap nilai IAP dan IRK pada mencithiperkolesterolemia. Sebanyak 25 ekor mencit jantan galur DDY dibagi menjadi 5 kelompok yaitu (1) Kontrol negatif diberi saline 0,9%; (2) Kontrol positif diberi minyak trans/MT 200 mg/kgBB; (3) MT+VCO 200 mg/kgBB; (4) MT+VCO 400 mg/kgBB; dan (5) MT+VCO 600 mg/kgBB. Perlakuan diberikan selama 56 hari. Darah diambil secara non invasif pada hari ke-57 melalui vena lateral ekor mencit untuk mengukur profil lipid plasma yaitu kolesterol total, trigliserida (TG), High Density Lippoprotein (HDL) dan Low Density Lipoprotein (LDL) plasma  menggunakan alat uji cepat Lipid Pro®. Nilai Indeks Aterogenik Plasma (IAP) yaitu log (TG/HDL) dan Indeks Risiko Koroner yaitu Kolesterol Total/HDL. Nilai IAP pada mencit yang diberi VCO adalah 0,08-0,22 (kategori risiko=rendah) berbeda nyata dari kelompok kontrol positif sebesar 0,82±0,078 (kategori risiko=tinggi). Nilai IRK pada mencit yang diberi VCO adalah 1,4-2,4 (kategori risiko=rendah) berbeda nyata dari kelompok kontrol positif 5,3±0,67 (kategori risiko=tinggi) (sig<0,05). Dosis VCO 600mg/kgBB adalah dosis optimal menurunkan risiko IAP dan IRK mencit hiperkolesterolemia dengan kategori risiko rendah. Pemberian VCO selama 8 minggu mampu menurunkan nilai IAP dan IRK pada mencit hiperkolesterolemia.
