Entre a criminalização e a vitimização
Authors: Morais Zuzarte Bravo André Luiz
Published: August 2020

Segundo estimativas recentes, a maior parte dos refugiados no mundo vive em áreas urbanas. Em 1997, o Alto Comissariado das Nações Unidas para Refugiados (ACNUR) apresentou sua primeira política oficial sobre o tema. Amplamente criticada por criminalizar o refúgio urbano, a Agência se viu obrigada a rever suas diretrizes e reconhecer a necessidade de proteção dessa população em uma nova política lançada em 2009. A partir do estudo de ambas, este artigo analisa o processo de construção institucional do refugiado urbano. Argumenta-se que, embora distintas em seu teor, ambas (re)produzem crenças normativas atreladas àfigura arquetípica do refugiado genuíno, a qual enfatiza vulnerabilidade e vitimização como marcadores de autenticidade da condição refugiada. Na política de 1997, tais traços foram mobilizados como forma de negar a legitimidade daqueles que se encontravam nas cidades; e, em 2009, como forma de justificar sua inclusão no espaço de assistência humanitária. A partir dessa leitura, este artigo sugere o diálogo com outras áreas do conhecimento como caminho para produção de políticas que rompam com uma visão estereotipada e que atentem para as múltiplas nuances que o urbano imprime ao refúgio.
Alemanha como Líder na Determinação de Ameaças Cibernéticas na União Europeia?
Authors: Reisdoerfer Bruna Rohr , Toso de Alcântara Bruna
Published: August 2020

A robustez econômica, as relações transatlânticas e a assertividade pragmática conferem à Alemanha legitimidade como Estado central para a tomada de decisão econômica na União Europeia. Todavia, no tocante a questões securitárias e de defesa, o país parece se colocar como líder relutante. Assim, seu papel de líder é contestado na esfera da política externa e de segurança. Todavia, desde o Caso Snowden (2013) a Alemanha destaca-se mundialmente por liderar projetos com ênfase na questão normativa do ciberespaço. Seria a Alemanha um país líder na área da segurança cibernética na Europa? Visa-se, pois, testar a hipótesede que a Alemanha possui papel de liderança na determinação de ameaças cibernéticas na União Europeia. Como o ciberespaço possui aspectos materiais e imateriais, este artigo busca a ótica de duas abordagens teóricas com ontologias distintas para a testagem da hipótese: o realismo neoclássico e o construtivismo convencional. Utiliza-se desenho de pesquisa de caso único, pois ele é propício para o aprofundamento da pesquisa em termos não apenas empíricos, mas também teóricos.

Authors: Lal Chiman , Garg Rajeev , Gupta Ghanshyam Das
Published: August 2020

Purpose:

The purpose of this research work was to evaluate the Pharmacokinetic (PK),
Pharmacodynamic (PD), and the distribution pattern of mucoadhesive microspheres of nifedipine.

Methods:

Firstly, the emulsion solvent evaporation technique was used to prepare the mucoadhesive
microspheres. The microspheres were characterized by Fourier Transform Infrared Spectroscopy (FTIR)
and in vivo studies were carried on Wistar rats.

Results:

Blood samples of rats were withdrawal at 2, 4, and 8 h time interval, after the administration of
Mucoadhesive microspheres of nifedipine (Mm-N) and the Saline solution of nifedipine (Ss-N) separately.
The Area Under the Curve (AUC) of Mm-N was seven foaled and Cmax around four foaled high
when compared with Ss-N with a significant difference P<0.005. Hypertension induced with DOCA
(deoxycorticosterone acetate) and the Blood Pressure (BP) of hypertensive rats were recorded at 0, 0.5,
1, 2, 3, 4, 5, 6 h time interval after given Mm-N and Ss-N to different groups. The BP of rats was better
control with Mm-N and regular after 2 h with high significant difference P<0.0001 however, the Ss-N
have an insignificant difference with P>0.05. The Mm-N was distributed in the upper part of the Gastrointestinal
Tract (GIT) after 8 h confirmed with the help of the fluorescence microscopic examination.

Conclusion:

This study indicates that the nifedipine was present in the blood for a more extended period,
and the blood pressure was easily controlled with mucoadhesive microspheres of nifedipine.
Therefore, mucoadhesive microspheres of nifedipine would be an excellent alternative over conventional
drug delivery for the treatment of hypertension.

Published: August 2020

Background:

The involvement of men in the prevention of mother-to-child HIV transmission (PMTCT) programs could accelerate the elimination of vertical transmission. Yet, little research has focused on HIV-positive male partners. This study determined predictors of male partners’ PMTCT knowledge and involvement in a tertiary hospital in northern Nigeria.

Methods:

A clinic-based sample of 401 HIV-positive male partners of women who delivered within 12 months prior were
interviewed using structured questionnaires. PMTCT knowledge and involvement scores were computed. Adjusted odd ratios (AOR) for predictors were derived from multivariate logistic regression models.

Results:

The proportion of respondents with adequate PMTCT knowledge was 40.9%. Less than half (43.6%) of the respondents participated in PMTCT, with median involvement score of 2.00 (interquartile range, IQR = 0, 5.0). One quarter of
respondents (25.7%, n =103) reported >1 sex partners, 10.5% consistently used condoms, and 20.7% had disclosed to all
partners. Father’s involvement in PMTCT was predicted by paternal education (AOR = 0.30; 95% Confidence Interval (CI):
0.12-0.77, no formal vs. post-secondary), HIV-positive child (AOR = 3.85; 95%CI: 1.41-10.54, yes vs. no), treatment duration (AOR = 4.17; 95%CI: 1.67-10.41, ≤1 vs. ≥10 years), disclosure to partner(s) (AOR = 1.21; 95%CI: 1.15-3.52, ‘disclosed to all’ vs. ‘not disclosed’), condom use (AOR = 5.81; 95%CI: 3.07-11.0, always vs. never), and PMTCT knowledge
(AOR = 0.62; 95%CI: 0.31-0.92, inadequate versus adequate).

Conclusion:

The involvement of fathers in HIV PMTCT programs was low and predicted by paternal education, HIVpositive child, duration of antiretroviral treatment, disclosure to partner, consistent condom use, and level of PMTCT
knowledge. Our findings will inform the development of policies to increase male partner involvement in PMTCT in Nigeria.

Published: August 2020

Combining palladium catalyzed reactions in one-pot reactions represents an efficient and
economical use of catalyst. The Suzuki-Miyaura cross-coupling has been proven to be a reaction
which can be combined with other palladium catalyzed reactions in the same pot. This mini-review
will highlight some of the latest examples where Suzuki-Miyaura cross-coupling reactions have been
combined with other palladium catalyzed reactions in one-pot reaction. Predominantly, examples
with homogeneous reaction conditions will be discussed in addition to a few examples from the authors
where Pd/C have been used as a catalyst.

Published: August 2020

Background:

The management of type 2 diabetes mellitus (T2DM) requires a complex and organized care that
includes patient lifestyle change. Additionally, emotional well-being is an important part of self-management, and it may
impair the individual’s adherence. Therefore, equipping them with the necessary coping and self-care techniques may be
an important step in managing diabetes.

Objective:

to evaluate the effect of interventions using established based-mindfulness protocols on glycemic control of
individuals T2DM.

Methods:

Data sources: Two electronic databases (PubMed and EMBASE) were searched from inception to December
2019. We limited our search to published studies in the English, Spanish and Portuguese language.
Study selection: Randomized clinical trials that assessed the effects of mindfulness in individuals with T2DM were
selected.

Data extraction:

Two authors independently assessed risk of bias and extracted data from the included trials. Data were
pooled using inverse-variance random-effects meta-analyses. The quality of evidence was assessed using the Grading of
Recommendations Assessment, Development and Evaluation (GRADE) system.

Results:

Four randomized trials were included. There were no differences in blood glucose change (mean difference
between groups (MD) -0.73mg/dl; 95% CI, -10.49; 9.02; I2 =0%; very low quality of evidence) or glycated hemoglobin
(MD 0.05%; 95%CI -0.22 to 0.32; I2 =29%; very low quality of evidence).

Conclusions:

Although the quality of current evidence is very low, our findings suggest that established protocols
involving mindfulness has no effect on blood glucose or glycated hemoglobin in individuals with T2DM. Indeed, largescale trials are needed to evaluate the contribution of mindfulness on glycemic control in the clinical practice.
A Review of Selected Adult Congenital Heart Diseases Encountered in Daily Practice
Authors: Bajwa Farhan , Jafri Syed M. , Ananthasubramaniam Karthik
Published: August 2020

The advancement in corrective surgical procedures and anaesthesia technology has resulted
in the increased survival of patients with Congenital Heart Diseases (CHD). Most of the surviving
CHD patients have successfully reached adulthood and those surviving adults now outnumber
the infants born with the CHD. Unfortunately, the surviving adults with CHD do not get proper
care due to either inconsistent follow-up or not getting care from a specialist in the field of CHD. It
is imperative for general practicing clinicians to be aware of the congenital diseases as well as the
current clinical recommendations. This manuscript reviews some of the common congenital diseases
seen in adults such as cardiac shunts, left heart obstructive lesions, and aortopathies.
β-1,3-glucan Attenuated Chronic Unpredictable Mild Stress-induced Cognitive Impairment in Rodents via Normalizing Corticosterone Levels
Authors: Khan Saniya H. , Khan Sheraz , Hashim Narmeen , Khan Inamullah
Published: August 2020

Background:

Chronic stress elevates the cortisol beyond normal levels, which affects
cognition including learning & memory. This injurious effect is primarily mediated via over excitation
of metabotropic glucocorticoid receptors (mGR).

Methods:

The present study was aimed to appraise the neuroprotective effects of naturally occurring
molecule β-1,3-glucan by interfering with stress-cortisol-mGR axis. Our data of virtual
screening (in silico) exhibited the promising interactions of β-glucan with the mGR. Therefore, the
study was extended to evaluate its efficacy (2.5, 5 and 10 mg/kg/ i.p) in an animal model of chronic
unpredictable mild stress (CUMS, 28 days) induced memory impairment.

Results:

Results of the current study revealed the β-glucan provided dose dependent protection
against deleterious effects of stress on learning and memory associated parameters observed in
Morris water maze (MWM) task. At higher tested doses, it has also significantly antagonized the
stress induced weight loss and corticosterone elevation.

Authors: Yang Libo , Wang Hongmei , Guo Jinying , Zheng Guanlin , Wei Dailin , Zhang Tie
Published: August 2020

Background and Objective:

Studies on the relationship of thyroid stimulating hormone
(TSH) within the reference range and thyroid autoimmunity with osteoporosis have produced conflicting
results. The objective of this study was to investigate the association of thyroid function and thyroid
autoimmune bodies (TPOAb and TgAb) with osteoporosis in euthyroid postmenopausal women.

Methods:

A total of 174 subjects were retrospectively included. Serum TSH, total T3, total T4,
TPOAb, TgAb, vitamin D, calcium and bone mineral density were measured. Correlation and logistic
multivariate regression analysis were performed.

Results:

Levels of TSH were lower in osteoporosis group (TSH: 2.03±1.08 vs 2.40±1.24 mIU/L,
p=0.040) while TT3 and TT4 levels were similar between the two groups. The positive percentage of
anti-TPO antibodies was higher in osteoporosis group (17.9% vs 6.7%, χ2= 5.13, p=0.024) while no
significant difference was observed for anti-Tg antibodies (17.9% vs 8.9%, χ2=3.05, p=0.081). The
Spearman correlation analysis showed that TSH levels were significantly correlated with lumbar spine
BMD (r= 0.161, P=0.035) and femoral neck BMD (r = 0.152, P= 0.045). Logistical regression analysis
revealed that low-normal TSH levels and positive TPOAb was an independent risk factor for osteoporosis
(OR: 0.698, 95% CI: 0.505-0.965, p=0.030; OR: 3.961, 95% CI: 1.176-13.345, p=0.026 respectively).

Conclusion:

The results showed that low-normal TSH levels and anti-TPO antibodies were independently
associated with the presence of osteoporosis in postmenopausal women.

Published: August 2020

Objective: This study was conducted to evaluate the relationship between pelvic measurements and body mass index (BMI) among pre-pregnancy young adult women in our population. Method: The sample group consisted of 83 midwifery students who agreed to participate in the study. The anthropometric pelvic measurements which are intercrestal diameter (IC), interspinous diameter (IS), intertrochanteric diameter (IT), intertuberous diameter (ITb), and Baudelocque diameter (anteroposterior diameter) was obtained by a single investigator with a pelvimeter. The program Statistical Package for Social Sciences (version 21.0) was used to create a descriptive analysis, and the Pearson correlation coefficient was performed to determine significance (p0.05). Results: The participants’ mean age was 19.72±1.16. The mean values of BMI, IC, IS, IT, ITb and Baudelocque diameter of participants were 22.71±3.26, 27.88±1.74, 25.31±2.01, 32.54±2.23, 12.41±1.51, and 20.40±1.62, respectively. Significant positive correlations were found between IC and BMI (r=0.434), IS and BMI (r=0.285), IT and BMI (r=0.051), and Baudelocque diameter and BMI (r=0.502). No significant differences were found between ITb and BMI (r=0.051 and p>0.05). Conclusion: The data indicates that IC, IS, IT, and Baudelocque diameter all correlate with BMI.
Rhythmic Haptic Cueing Using Wearable Devices as Physiotherapy for Huntington Disease: Case Study
Authors: Georgiou Theodoros , Islam Riasat , Holland Simon , van der Linden Janet , Price Blaine , Mulholland Paul , Perry Allan
Published: August 2020

Background

Huntington disease (HD) is an inherited genetic disorder that results in the death of brain cells. HD symptoms generally start with subtle changes in mood and mental abilities; they then degenerate progressively, ensuing a general lack of coordination and an unsteady gait, ultimately resulting in death. There is currently no cure for HD. Walking cued by an external, usually auditory, rhythm has been shown to steady gait and help with movement coordination in other neurological conditions. More recently, work with other neurological conditions has demonstrated that haptic (ie, tactile) rhythmic cues, as opposed to audio cues, offer similar improvements when walking. An added benefit is that less intrusive, more private cues are delivered by a wearable device that leaves the ears free for conversation, situation awareness, and safety. This paper presents a case study where rhythmic haptic cueing (RHC) was applied to one person with HD. The case study has two elements: the gait data we collected from our wearable devices and the comments we received from a group of highly trained expert physiotherapists and specialists in HD.

Objective

The objective of this case study was to investigate whether RHC can be applied to improve gait coordination and limb control in people living with HD. While not offering a cure, therapeutic outcomes may delay the onset or severity of symptoms, with the potential to improve and prolong quality of life.

Methods

The approach adopted for this study includes two elements, one quantitative and one qualitative. The first is a repeated-measures design with three conditions: before haptic rhythm (ie, baseline), with haptic rhythm, and after exposure to haptic rhythm. The second element is an in-depth interview with physiotherapists observing the session.

Results

In comparison to the baseline, the physiotherapists noted a number of improvements to the participant’s kinematics during her walk with the haptic cues. These improvements continued in the after-cue condition, indicating some lasting effects. The quantitative data obtained support the physiotherapists’ observations.

Conclusions

The findings from this small case study, with a single participant, suggest that a haptic metronomic rhythm may have immediate, potentially therapeutic benefits for the walking kinematics of people living with HD and warrants further investigation.

The Effect of Innovation Capabilities of Health Care Organizations on the Quality of Health Information Technology: Model Development With Cross-sectional Data (Preprint)
Authors: Esdar Moritz , Hübner Ursula , Thye Johannes , Babitsch Birgit , Liebe Jan-David
Published: August 2020

BACKGROUND

Large health organizations often struggle to build complex health information technology (HIT) solutions and are faced with ever-growing pressure to continuously innovate their information systems. Limited research has been conducted that explores the relationship between organizations’ innovative capabilities and HIT quality in the sense of achieving high-quality support for patient care processes.

OBJECTIVE

The aim of this study is to explain how core constructs of organizational innovation capabilities are linked to HIT quality based on a conceptual sociotechnical model on innovation and quality of HIT, called the IQHIT model, to help determine how better information provision in health organizations can be achieved.

METHODS

We designed a survey to assess various domains of HIT quality, innovation capabilities of health organizations, and context variables and administered it to hospital chief information officers across Austria, Germany, and Switzerland. Data from 232 hospitals were used to empirically fit the model using partial least squares structural equation modeling to reveal associations and mediating and moderating effects.

RESULTS

The resulting empirical IQHIT model reveals several associations between the analyzed constructs, which can be summarized in 2 main insights. First, it illustrates the linkage between the constructs measuring HIT quality by showing that the professionalism of information management explains the degree of HIT workflow support (R²=0.56), which in turn explains the perceived HIT quality (R²=0.53). Second, the model shows that HIT quality was positively influenced by innovation capabilities related to the top management team, the information technology department, and the organization at large. The assessment of the model’s statistical quality criteria indicated valid model specifications, including sufficient convergent and discriminant validity for measuring the latent constructs that underlie the measures of HIT quality and innovation capabilities.

CONCLUSIONS

The proposed sociotechnical IQHIT model points to the key role of professional information management for HIT workflow support in patient care and perceived HIT quality from the viewpoint of hospital chief information officers. Furthermore, it highlights that organizational innovation capabilities, particularly with respect to the top management team, facilitate HIT quality and suggests that health organizations establish this link by applying professional information management practices. The model may serve to stimulate further scientific work in the field of HIT adoption and diffusion and to provide practical guidance to managers, policy makers, and educators on how to achieve better patient care using HIT.
Engaging Institutional Stakeholders to Develop and Implement Guidelines for Recruiting Participants in Research Studies Using Social Media: Mixed Methods, Multi-Phase Process (Preprint)
Authors: Flood-Grady Elizabeth , Solberg Lauren B , Baralt Claire , Meyer Meghan , Stevens Jeff , Krieger Janice L
Published: August 2020

BACKGROUND

Limited regulatory guidance surrounding the use of social media channels for participant recruitment is an interdisciplinary challenge. Establishing stakeholder-informed procedures is essential for ethical and effective use of social media for participant recruitment.

OBJECTIVE

This study aims to provide replicable procedures for developing and implementing guidelines for using social media to recruit participants in research studies.

METHODS

Social media use cases at the university were used to identify institutional stakeholders for the initiative. After establishing workflow procedures, a scoping review of web-based materials about recruitment and research on the internet and social media from 19 peer institutions and 2 federal agencies was conducted to inform the structure of the policies and procedures. End users (investigators and study coordinators; N=14) also provided feedback on the policies and procedures and implementation.

RESULTS

Representatives (n=7) from 5 institutional offices and 15 subject-matter experts from 5 areas were identified as stakeholders in the development of policies and procedures. Peers with web-based materials (n=16) identified in the scoping review revealed 4 themes that served as a basis for developing our policies and procedures. End user feedback further informed the policies and procedures and implementation. A centrally managed social media account for communicating with participants and hosting advertising campaigns on social media was also established and, when combined with the policies and procedures, resulted in 39 advertising campaigns, and 2846 participants were enrolled in health and clinical research studies.

CONCLUSIONS

Our policies and procedures allow research teams to harness the potential of social media to increase study recruitment and participation; the transparent, stakeholder-informed process can be replicated by institutional administrators to establish policies and procedures that meet the interests and needs of their research community.

Authors: Vorel Ethan S. , Toto Regina L , Balamuth Fran , Chang Todd P.
Published: August 2020

UNSTRUCTURED

The global COVID-19 pandemic has necessitated innovation in medical education, specifically the adaptation of current curricula with expanded accessibility and the creation of novel curricula through the use of technology. Even prior to the pandemic, applications in AR and VR have shown promise in enhancing medical education for learners across many different specialties. AR and VR have the potential to create quality educational experiences that do not involve patient contact, making them particularly relevant in current times. VR shows promise in enhancing medical resuscitation teaching; AR has not been as well studied to date. AR offers the advantage of allowing learners to function in their usual environment with the addition of real time feedback through digital media. If successful, the incorporation of AR into medical simulation scenarios has the potential for broad application in emergency medical education.

Published: August 2020

In Indonesia, gold is typically mined out from epithermal, porphyry and skarn deposit types occurred within volcanic belts along magmatic arc or active continental margin setting. Numerous gold prospects, however, are recently discovered in association with metamorphic and sedimentary rocks. This paper is aimed to discuss a preliminary study on the occurrences and characteristics of the sedimentary rock-hosted low-sulfidation (LS) epithermal gold mineralization in Bastem (Bessengan Tempe) prospect, Luwu district, Sulawesi Island, Indonesia. Detailed geological and hydrothermal alteration mapping was performed to understand the distribution and characteristics of ore mineralization. Representative ore samples taken were analysed for ore chemistry by means of Fire Assay – Atomic Absorption Spectrometry (FA-AAS) and Acid Geochemical Digest - Atomic Absorption Spectrometry (GA-AAS). The results from this work that the Bastem prospect is stratigrapically occupied by Tertiary sedimentary rocks of Toraja formation, which is adjacent to volcanic rocks of Lamasi formation. Gold-bearing quartz±carbonate veins are hosted by mudstone and siltstone of Toraja formation. The quartz-carbonate veins show a typical LS epithermal open space filling texture containing erratic gold grade of up to 7.16 g/t with relatively high besemetals (Pb and Zn) grades of up to >0.4 and >1%, respectively. Based on those various features, the LS epithermal deposit is categorized as “carbonate-basemetal-gold mineralization type”, which might be originated in back arc rift/basin setting. This ‘unconventional’ sedimentary rock hosted-gold mineralization type would be the new target of gold exploration in Indonesia.

Published: August 2020

The increasing number of residents demands the provision of settlement facilities and infrastructure. Limited land is an obstacle to the development in the horizontal direction, especially the use of green open land which will cause land conversion. The limitation of the building height regulated by local regulations, as well as the local wisdom, namely vertical holiness can be a challenge related to the idea of building multi-storey buildings. When you want to enter the lower floors of the building, there is a feeling of doubt because there are other residents on the upper floors who step over. This study aims to reveal the relationship of vertical holiness with multi-storey building design and formulate vertical holiness as an effort to implement it in a design so that it can be accepted by the community. This study uses a methodology to examine the problem by interviewing the stakeholders and filling out the questionnaire, therefore, the relationship between vertical holiness and multi-storey building design can be obtained. The results of the study clearly confirm that there is indeed a correlation between vertical holiness and multi-storey building design. Thus, the design should pay attention to this vertical holiness. The study also encourages that the formulation of vertical holiness should be legally stated in regulation so that it is easily understood and accepted by the community.

Vocalizing during gaps in anthropogenic noise is an uncommon trait for enhancing communication in songbirds
Authors: Proppe Darren S. , Finch Emily
Published: August 2020

Mounting evidence suggests that anthropogenic noise neg-atively impacts many wildlife species, including songbirds. One mechanism by which noise affects songbirds may be through acoustic obstruction to their systems of vocal communication. However, many species increase the amplitude or pitch of their vocalizations, which may partially mitigate the impact of high noise levels. When the amplitude of anthropogenic noise varies over time, such as near a moderate-use highway, short gaps between noise events may also provide an important oppor- tunity for communication. But, whether songbirds adjust vocalization rates rapidly to avoid overlap with noise is unknown for most species. We used acoustic playback to expose song- birds to simulated road noise during the dawn chorus in oth- erwise quiet habitats. We measured vocalization rates under ambient conditions and during quiet gaps embedded within playback of road noise to assess whether a community of songbirds, and nineteen individual species, vocalize more reg- ularly during noise gaps. There were no significant differences in community-wide acoustic output. Species-specific analysis revealed that only four species altered their vocal rates during quiet gaps in noise, but that the direction of the effect varied by species. Point count results revealed that birds generally remained on site for the duration of the experiment, suggesting that abandonment of noisy locations was unlikely to confound our results. In sum, increasing vocal output during short gaps in noise occurred in only a handful of species, perhaps con- tributing to the limited number of species that are found within noisy habitats.

Lahan gambut mencakup 3% dari daratan bumi dan menyimpan sebagian besar

sumber daya karbon dunia yang kurang lebih setara dengan 1/3 dari karbon dalam tanah global. Selama kurun waktu 12 tahun terjadi penurunan kandungan karbon sebesar 438 juta ton di provinsi Jambi yang disebabkan oleh perubahan penggunaan lahan, pembukaan lahan, sisem drainase dan dan kebakaran lahan gambut. Adanya penurunan jumlah cadangan karbon tersebut mengindikasikan karbon yang semula berada pada lahan gambut telah teremisi ke atmosfer sehingga berdampak pada pemanasan global. Hutan Lindung Gambung (HLG) Londerang adalah salah satu ekosistem hutan gambut tropis yang masih tersisa di Sumatera bagian tengah dengan kondisi sangat kritis akibat peristiwa kebakaran hutan, dengan demikian fungsi ekologinya tidak lagi berjalan optimal. Penelitian ini bertujuan untuk memprediksi jumlah cadangan karbon bawah permukaan, mengetahui potensi emisi karbon serta memberikan arahan pengelolaan karbon di areal hutan lindung gambut Londerang, Kabupaten Tanjung Jabung Timur. Pelaksanaan penelitian ini menggunakan Metode Survei. Penentuan titik-titik pengamatan dibuat secara transek yaitu tegak lurus terhadap tanggul sungai dengan grid 500 x 1000 m sehingga diperoleh 38 titik pengamatan pada lokasi penelitian seluas 19.00 Ha. Jumlah total cadangan karbon bawah permukaan di areal penelitian seluas 19.00 Ha adalah 6.654.152,19 ton atau 3502 ton/Ha. Potensi emisi karbon yang dihasilkan akibat hilangnya gambut setebal 10 cm karena terbakar pada lahan penelitian seluas 1900 Ha adalah sebesar 12367,1 ton C atau 6,509 ton/Ha. Upaya-upaya yang perlu dilakukan untuk menekan laju emisi karbon dan mempertahankan fungsi lahan gambut sebagai pengikat karbon dalam jumlah yang besar adalah dengan melakukan restorasi hidrologi dan revegetasi.
