Published: September 2021

Palm oil is one of the largest agricultural products in Indonesia and has a high economic value and can improve the welfare of oil palm farmers. The amount of oil palm fruit production is not always stable or increasing, but increases up and down which is influenced by many factors. This study aims to estimate the average amount of oil palm fruit production every year and prepare anticipatory steps in the event of a decrease in oil palm fruit production. The image processed in this study was the production of palm fruit in a few years which was generated from the results of oil palm plantations. Furthermore, data is processed using the Single Moving Avarage method. This method is a method of forecasting or predictions using a number of actual data to generate predictive values ​​in the future. The results of testing on the single moving average method can be seen forecasts of oil palm fruit production in 2021 using Moving Averge 3 of 200.749 tons with Mean Absolute Deviation 19.604, Mean Squared Error 456.963.281 and Mean Absolute Percent Error 10,0%. Moving Averge 4 was 206.771 tons with the Mean Absolute Deviation 27.333, Mean Squared Error 752.202.579 and Mean Absolute Percent Error 14,2%. Moving Averge 5 was 210.908 tons with Mean Absolute Deviation 26.890, Mean Squared Error 723.072.100 and Mean Absolute Percent Error 14.1%. The test results using the Single Moving Average method can be concluded that forecasting using Moving Average 3 can be used because the relative error level is smaller than Moving Average 4 and 5, with the value of the Mean Absolute Percent error of 10.0% and Mean Absolute Deviation 19.604.

Развитие системы беспилотной авиации, независимо от ее предназначения и структурной принадлежности, предполагает согласованные усилия заинтересованных лиц (руководства, ученых и конструкторов, специалистов испытательных комплексов, преподавателей, инструкторов теоретического и практического обучения операторов управления летательными аппаратами и их полезными нагрузками) по совершенствованию технических характеристик и функционала беспилотных воздушных судов, а также по формированию соответствующих компетенций у персонала эксплуатирующих подразделений. Очевидным является тот факт, что все перечисленные мероприятия наиболее полно могут быть реализованы в рамках функционирования специальных центров развития беспилотных авиационных систем государственного или ведомственного уровня.
The development of unmanned aircraft system, regardless of its purpose and structural affiliation, involves the concerted efforts of stakeholders (management, scientists and designers, specialists of test complexes, tutors, as well as theoretical and practical instructors for operators of aircraft and their payloads control) to improve the technical characteristics and functionality of unmanned aircraft, as well as to create appropriate competencies among the personnel of operating units. It is obvious that all these measures can be fully implemented within the framework of special centers for unmanned aircraft systems of state or departmental level.

L’écoute du/de la psychologue dans un service de soin somatique
Authors: Bergheimer Sophie , Lindenmeyer Cristina , Livia Tourinho Moreto Maria 
Published: September 2021

Les pratiques de modification du corps humain (dans des visées réparatrices, esthétiques, identitaires, d’augmentation ou de performance) sont de plus en plus courantes. Cependant, ces pratiques ont des effets sur le rapport intime que le sujet entretient avec son corps ainsi que sa façon de se mettre en relation avec les autres. Depuis plusieurs années de nombreuses recherches s’intéressent à ces différentes techniques d’intervention sur le corps et à leurs effets subjectifs. Dans cet article, nous proposons de réfléchir à l’impact de ces interventions sur l’écoute du/de la psychologue travaillant dans les services où est généré ce type de démarche. Le cas Iiro, présenté par Winnicott (1970 ; 1972), sera analysé comme paradigme de l’écoute face aux patient.e.s ayant une déformation corporelle. Car cette écoute de la particularité de ce corps est parfois fascinante, d’autres fois dérangeante, mais surtout est une écoute qui revisite les temps plus précoces et originaux de l’habitation de la psyché dans le corps, et du corps dans la psyché. Cela dit, nous soutenons que parce que cette écoute s’inscrit comme une ouverture vers des zones primitives de la psyché, elle nécessite un travail conséquent sur le contre-transfert.
Les « communs négatifs »
Authors: Monnin Alexandre 
Published: September 2021

Les communs désignent généralement des ressources partagées qui ont une utilité pour une communauté qui en prend soin, c’est-à-dire des effets positifs. La notion de « communs négatifs » s’attache aux problèmes soulevés par la gestion de certaines réalités dont les effets sont négatifs notamment dans le domaine environnemental : déchets, centrales nucléaires, mais aussi d’autres éléments dont nous allons hériter à l’avenir et dont il va bien falloir prendre soin. Plus les sociétés capitalistes se développent, plus elles perdent leur capacité à absorber ce qu’elles produisent en excès, reléguant ces déchets dans les zones les plus pauvres ou bien dans les profondeurs de la terre et des océans. À côté de cela, d’autres réalités, inassimilables à des déchets, nous privent de futur, de par leur simple existence. Comment politiser le traitement qu’il convient d’y apporter ? C’est à cette question qu’entend répondre le second pan de la réflexion ouverte par les communs négatifs.
Les « Objets-reliques » et l’inquiétante étrangeté des images transgénérationnelles
Authors: Mokdad Zmitri Meriem 
Published: September 2021

L’auteure désigne par « objets-reliques » ces objets matériels transmis de génération en génération. Elle les suppose incarner et susciter l’inquiétante étrangeté des images psychiques transgénérationnelles en même temps que détenir le potentiel de les transformer pour les mettre/remettre au service d’un processus de subjectivation fluide et désaliéné. En s’appuyant sur deux vignettes cliniques, l’auteure met en lumière ce travail de transformation à travers ce qu’elle désigne par le « fantasme prosopopéïque » et la « pulsion portraitiste ».
Intra- and interspecific discrimination of Scorpaena species from the Aegean, Black, Mediterranean and Marmara seas
Authors: Yedier Serdar , Bostanci Derya 
Published: September 2021

This study was conducted to discriminate five Scorpaena species and populations of each species according to morphometric characters. A total of 1865 fish specimens were collected from the eight locations in the four Turkish seas: Antalya, Balıkesir, Çanakkale, Hatay, İzmir, Marmara Ereğlisi, Ordu and Şile. In the study, 26 morphometric traits were measured for intra- and interspecific discrimination of five Scorpaena species. The data were subjected to analysis of variance, principal components analysis (PCA) and canonical discriminant analysis. As results of the PCA, 10 traits for S. maderensis and S. scrofa, 12 traits for S. elongata and 13 traits for S. notata and S. porcus were found to be important for intraspcific discrimination. The overall classification scores of intraspecific discrimination were determined as 94.6% for S. elongata, 90.5% for S. maderensis, 96.7% for S. notata, 96.5% for S. porcus and 92.2% for S. scrofa. The PCA indicated that 13 morphometric measurements among the 26 traits are important in the interspecific discrimination of five Scorpaena species. The cross-validated canonical discriminant analysis was correctly classified as 97.4% at the Scorpaena species level. The discrimination of correctly classified species ranged from 94.8% to 100%. Finally, we demonstrated that the morphometric characters examined in the present study can be used successfully in the intra- and interspecific discrimination of Scorpaena species from different habitats.
Cost-effectiveness of Descemet stripping automated endothelial keratoplasty versus penetrating keratoplasty in patients with endothelial dysfunction in India
Authors: Shah Pooja , Mukhija Ritika , Gupta Noopur , Vanathi M , Tandon Radhika 
Published: September 2021

Purpose:
The aim of this study was to compare the cost-effectiveness and perform cost-utility analysis of Descemet stripping automated endothelial keratoplasty (DSAEK) vs. penetrating keratoplasty (PK) in Indian population.

Methods:
This was an institutional, ambispective, observational study. Patients who underwent PK or DSAEK for endothelial dysfunction were included and followed up for 2 years; those with other ocular comorbidities were excluded. The analysis was performed from the patient’s perspective receiving subsidized treatment at a tertiary care hospital. Detailed history, ophthalmic examination, total expenditure by patient, and clinical outcomes were recorded. The main outcome measures were best spectacle-corrected visual acuity (BSCVA), graft survival (Kaplan–Meier survival estimates), incremental cost-effectiveness ratio (ICER), and incremental cost-utility ratio (ICUR). Utility values were based on quality-adjusted life years (QALYs) associated with visual acuity outcomes. Statistical analysis was performed using SPSS software package, version 12.1; a value of P < 0.05 was considered statistically significant.

Results:
A total of 120 patients (PK: 60, DSAEK: 60) were included. At 2 years, for a similar logMAR BSCVA, [PK (0.32 ± 0.02), DSAEK (0.25 ± 0.02); P = 0.078], the overall cost for PK (13511.1 ± 803.3 INR) was significantly more than DSAEK (11092.9 ± 492.1 INR) (difference = 1952.6 INR; P = 0.01). ICER of DSAEK relative to PK was –39,052 INR for improvement in 1 logMAR unit BSCVA. ICUR of DSAEK relative to PK was –1,95,260 INR for improvement in 1 QALY.

Conclusion:
DSAEK was more cost-effective than PK in patients with endothelial dysfunction at 2 years.
Emergency canthotomy and cantholysis - Factors affecting confidence among ophthalmic trainees in the United Kingdom
Authors: Lim Christina S , Malick Huzaifa , Berry-Brincat Antonella 
Published: September 2021

Purpose:
Retrobulbar hemorrhage from trauma is the most common cause of orbital compartment syndrome. Emergency canthotomy and cantholysis is a vision-saving procedure. We sought to identify confidence among ophthalmic trainees in this procedure as well as any relevant factors that have any impact.

Methods:
An online, confidential anonymous questionnaire was distributed to ophthalmology training groups in the UK. Questions explored the participant’s stage of training and grade and confidence in this area as well as their ophthalmic experience in terms of training courses attended and elective versions of the procedure performed.

Results:
We received 45 completed responses from the survey. 20/23 (87%) of junior trainees had not performed an emergency canthotomy/cantholysis to date, whereas 19/22 (86%) of senior trainees had performed between 1 and 5 such procedures. 15/23 (65%) of junior trainees had not performed an elective canthotomy compared to only 3/22 (14%) of the senior trainees. We found that the main factors that were associated with increased confidence level were the higher numbers of emergency and elective cases performed, training courses, and previous oculoplastic surgery rotation (P = 0.0001).

Conclusion:
From our survey, we found low confidence levels among junior trainees due to limited exposure. Confidence appeared to be linked to both elective and emergency surgical experience of the procedure as well as training course and having worked in an oculoplastic surgery firm. Changes to training portfolio requirements for junior trainees to incorporate early oculoplastic experience may help to achieve this on a national scale.
Ten-year outcome of anti-vascular endothelial growth factor treatment for neovascular age-related macular degeneration
Authors: Upasani Deepa , Dhingra Narendra 
Published: September 2021

Purpose:
The aim of this study was to report the 10-year visual outcome in eyes treated with anti-vascular endothelial growth factor (anti-VEGF) agents for neovascular age-related macular degeneration (nAMD) and to assess the impact of switching treatment as part of routine clinical care.

Methods:
Electronic records of treatment-naïve eyes initiated on intravitreal ranibizumab between January and December 2009 were accessed. The primary outcome measured was the change in visual acuity (VA) in Early Treatment of Diabetic Retinopathy Study letters. The frequency and reasons for treatment discontinuation during each year of follow-up and the impact of switching from ranibizumab to aflibercept were some of the secondary outcomes.

Results:
Of the 223 eyes (203 patients), 60 eyes completed 10 years of continuous follow-up. After a mean follow-up of 121.4 months, VA declined by 5.6 letters (95% confidence interval [CI] –0.25 to –11.1, P = 0.04). Final VA of ≥70 letters was seen in 20% of eyes and 35% had VA ≤ 35 letters. VA gain of ≥10 letters was seen in 23% and loss of ≥10 letters was seen in 40% of the eyes. Twenty-nine eyes remained on ranibizumab monotherapy and 31 switched to aflibercept. Switched eyes showed a visual decline of 7.1 letters (5.5 letters in monotherapy eyes, P = 0.32) and received a significantly higher number of injections (39.6 ± 9.9 vs. 24.4 ± 13.1, P < 0.0001). Patients discontinuing treatment were older and had lower baseline vision compared to completers.

Conclusion:
VA declined below the baseline after 10 years of follow-up and switching did not have any effect on the final visual outcome.
Ocular Surface Disease Index© and the five-item dry eye questionnaire: A comparison in Indian patients with dry eye disease
Authors: Chatterjee Samrat , Agrawal Deepshikha , Chaturvedi Pravda 
Published: September 2021

Purpose:
To compare the suitability of the Ocular Surface Disease Index (OSDI) and the 5-item Dry Eye Questionnaire (DEQ-5) in Indian patients with dry eyes.

Methods:
This cross-sectional study evaluated the OSDI and DEQ-5 in patients with tear film abnormalities. Tear film breakup time, tear film height, Schirmer’s I, lissamine green staining, and meibomian gland expressibility were performed on each patient.

Results:
There were 101 patients with symptoms and/or signs of tear film abnormality. Both OSDI and DEQ-5 questionnaires significantly correlated (ρ = 0.566, P < 0.0001) with each other. The OSDI questionnaire showed a good correlation with all dry eye tests, whereas the DEQ-5 correlated significantly only with the tear film breakup time and the lissamine green score. None of the questionnaires correlated with meibomian gland expressibility. The Bland–Altman analysis revealed a marginal bias (−0.01 unit) for DEQ-5. The DEQ-5 scored higher in patients with mild symptoms. While 101 (100%) patients answered all the questions in the DEQ-5, only 19 (18.8%) patients answered all the questions in the OSDI questionnaire. The least responses were recorded in the vision-function-related and environmental trigger subscales of the OSDI.

Conclusion:
The OSDI and DEQ-5 scores showed a moderate correlation. The OSDI questionnaire correlated with a higher number of dry eye tests than the DEQ-5. The large number of skipped questions in the vision-function-related and environmental trigger subscales of the OSDI suggests that the questionnaire is not adequately adapted to the Indian population. Patients with a negative OSDI score should be reassessed with the DEQ-5 to exclude symptom positivity.
Multifocal electroretinography-assisted anatomical and functional evaluation of subthreshold green laser in acute central serous chorioretinopathy
Authors: Goel Neha , Mehta Aanchal , Gupta A K 
Published: September 2021

Purpose:
To compare observation versus subthreshold green laser (STL) in acute central serous chorioretinopathy (CSC) in terms of anatomical and functional outcomes.

Methods:
Prospective randomized interventional study. 30 eyes with the first episode of acute CSC underwent complete ophthalmologic examination, measurement of best-corrected Snellen visual acuity (BCVA), contrast sensitivity (CS), fundus fluorescein angiography (FFA), spectral-domain optical coherence tomography (SD-OCT), and multifocal electroretinography (mfERG) at baseline. Patients were randomized equally to group A (observation) or group B (STL using 532 nm wavelength applied to the leakage point). Outcome measures included BCVA, CS, central foveal thickness (CFT), and mean macular thickness (MMT) on SD-OCT and P1 amplitude and implicit time (IT) on mfERG. Patients were followed up for 6 months.

Results:
Mean BCVA was comparable between the two groups on follow up; however, mean CS was significantly higher in group B at 6 months (P = 0.032). CFT was significantly lower in group B at 1 month (P = 0.001) and 3 months (P = 0.049); however, this difference was not maintained at 6 months (P = 0.265). P1 amplitude and IT in all 5 rings were comparable between the two groups at baseline. On follow up, P1 amplitude of ring 1 became significantly higher in group B at 3 months (P = 0.036) and 6 months (P = 0.022).

Conclusion:
Immediate treatment of acute CSC with STL, as compared to conservative management, leads to more rapid resolution on SD-OCT and superior functional outcomes as evidenced by CS and mfERG.
Masked comparison of trypan blue stain and potassium hydroxide with calcofluor white stain in the microscopic examination of corneal scrapings for the diagnosis of microbial keratitis
Authors: Rathi Varsha M , Murthy Somasheila I , Mitra Sanchita , Yamjala Balakrishna , Mohamed Ashik , Sharma Savitri 
Published: September 2021

Purpose:
To evaluate the efficacy of trypan blue in direct microscopic examination of corneal scrapings in the diagnosis of non-viral microbial keratitis.

Methods:
In a prospective, interventional, masked study, 82 consecutive patients were investigated. Direct microscopic examination of the corneal scrapings involved three smears stained with potassium hydroxide with calcofluor white (KOH + CFW), Gram stain (not analyzed), and trypan blue stain and culture for bacteria, fungus, and Acanthamoeba. While KOH + CFW stained slides were examined under a fluorescence microscope, trypan blue-stained slides were examined by two microbiologists (masked to KOH + CFW and culture results) under normal light microscopy. Thirty samples were reexamined for interobserver and intraobserver variability.

Results:
Out of 82 samples, fungal/fungus-like elements were seen in 48 (58.5%) in KOH + CFW and 38 (46.3%) in trypan blue stain. One microsporidial case, detected in KOH + CFW was negative in trypan blue stain (culture not done). Fungal growth was positive in 23 out of 81 (28.3%) cases cultured, single bacterial species in 18 (22.2%), Pythium insidiosum in three, mixed bacteria and fungus/Pythium in 7 (8.6%), Acanthamoeba in none and 30 (37.0%) samples were sterile. With culture as gold standard, the respective sensitivity (84.9%, 75.7%) and specificity (90.9%, 68.2%) of KOH + CFW stain and trypan blue stain were comparable (p = 0.16, P = 0.06). The interobserver linear weighted kappa score between the two microbiologists was 1.00 while it was 0.86 for intraobserver agreement.

Conclusion:
Trypan blue stain, an easily available dye to ophthalmologists, is highly efficacious in the diagnosis of fungal keratitis.
Optimizing lens constants specifically for short eyes: Is it essential?
Authors: Shrivastava Ankur K , Nayak Swatishree , Mahobia Ashish , Anto Mary , Kacher Rajaram , Kumar Ajay 
Published: September 2021

Purpose:
Optimization of lens constants is a critically important step that improves refractive outcomes significantly. Whether lens constants optimized for the entire range of axial length would perform equally well in short eyes is still a matter of debate. The aim of this study was to analyze whether lens constants need to be optimized specifically for short eyes.

Methods:
This retrospective observational study was conducted at a tertiary care hospital in Central India. Eighty-six eyes of eighty-six patients were included. Optical biometry with IOLMaster 500 was done in all cases and lens constants were optimized using built-in software. Barrett Universal II, Haigis, Hill-RBF, Hoffer Q, Holladay 1, and SRK/T formulae were compared using optimized constants. Mean absolute error, median absolute error (MedAE), and percentage of eyes within ±0.25, ±0.50, ±1.00, and ±2.00 diopter of the predicted refraction, of each formula were analyzed using manufacturer’s, ULIB, and optimized lens constants. MedAE was compared across various constants used by Wilcoxon signed-rank test and among optimized constants by Friedman’s test. Cochran’s Q test compared the percentage of eyes within ± 0.25, ±0.50, ±1.00, and ± 2.00 diopter of the predicted refraction. A value of P < 0.05 was considered statistically significant.

Results:
Optimized constant of Haigis had significantly lower MedAE (P < 0.00001) as compared to manufacturers. However, there was no statistically significant difference between ULIB and optimized constants. Postoptimization, there was no statistically significant difference among all formulae.

Conclusion:
Optimizing lens constants specifically for short eyes gives no added advantage over those optimized for the entire range of axial length.
