Published: September 2021

Highlight Research:Spawning potential ratio (SPR) based on the length and frequency data is a substitution approach for data-poor management in fisheriesGonad maturity is an indicator to ensure recruitment and stock sustainability. Therefore important to evaluate the impact of fishing capture on the size and length of fishSpawning potential ratio of skipjack relatively low and potential medium impact on risk sustainability AbstractWhen data is limited, management measurement from fisheries makes it possible to use natural history data to analyze the potential spawning ratio (SPR). This research aimed to determine skipjack fish management measure from the Indian Ocean landed at Cilacap Fishing Port through the SPR approach. The study was conducted in December 2014 to March 2015 using length and reproduction data. The analysis consisted of the size structure, growth rate, and asymptotic length that were analyzed using FISAT II program and length at fifty percent maturity (Lm50). The SPR analysis used SPR software from the application in http://barefootecologist.com.au/lbspr. The size distributions of skipjack obtained were a length of 220-790 mm and an average dominant length of 311-371 mm. The asymptotic length obtained was 831.57 mm, with growth rate and natural mortality of 1.1 and 1.44 per year respectively. The population proportion of 50% reaching gonad maturity (Lm50) was found at a length of 494.75 mm and (Lm95 = 522.39 mm) with an M/k ratio of 1.309. The length selectivity level was caught 50% (SL50 = 317.36 mm) and 95% (SL95 = 373.1 mm). The spawning potential ratio (SPR) ranged from 2-4 with an average of 4% during observation. The SPR potential, which is lower from the standardized threshold of 40%, indicates many young fish populations are caught, and the potential for overfishing is high, high risk, and low sustainability.

Highlight ResearchThe mortality of lobster seeds by predators in the first year is 96.0-99.4%It takes technology to catch seeds before being eaten by predatorsApplication of sound wave-based attractor technology to lobstersDo lobsters have the ability to hear sound waves?The lobster's sense of hearing begins to function from the puerulus stage AbstractIndonesia is a country that produces abundant lobster seeds (puerulus), however, there is a paradox, where natural mortality in the first year since entering the settlement phase can reach 96.0-99.4%. The use of lobster resources, especially in the puerulus stage, for cultivation, is very strategic. Therefore, it is necessary to improve puerulus fishing technology. In the capture fisheries sector, the use of the sense of hearing in fish resources has been carried out to increase catch productivity, by utilizing sound wave-based attractors’ technology. For lobster resources, to what extent is this technology applicable? Underwater sound waves are a phenomenon of compression and expansion of a medium as sound energy passes through it. This aspect of the study is still new and very prospective. The purpose of this review article is to answer some basic questions: Can lobsters be able to hear sounds that come from their surroundings, since when do lobsters sense of hearing begin to function, and anatomically what kind of auditory organs are in lobsters. The results of the review conclude as follows: lobsters have senses that are able to perceive or listen to sound waves (sound) from their surrounding environment, this ability has been possessed by lobsters since they were in the postlarva or puerulus stage. Anatomically, the organs that act as the sense of hearing in lobsters are: receptors on the body surface, chordotonal organs and statocyst organs.

Highlight Research AbstractChitin is a natural compound found abundantly in shrimp shells. Chitin can be degraded to produce N-acetylglucosamine, which has wide applications in the food and pharmaceutical fields. Fermentation using chitinolytic microorganisms can be used to produce N-acetylglucosamine from shrimp shells’ chitin. One of the strong chitinolytic bacteria that was isolated from previous research was Providencia stuartii. To provide better stability and efficiency in fermentation, P. stuartii cells were immobilized using entrapment method in papaya trunk wood. The aims of this research were to determine the optimum papaya trunk wood size, ratio of papaya trunk wood and growth medium, as well as the optimum fermentation cycle to produce N-acetylglucosamine from P. vannamei shrimp shells using submerged fermentation method. The research used experimental method with treatment of different sizes of papaya trunk wood (1 x 1 x 1 cm3, 1.5 x 1.5 x 1.5 cm3, and 2 x 2 x 2 cm3), different ratio of papaya trunk wood and growth medium (1:10, 1:15 and 1:20), and 4 fermentation cycles. Results showed that papaya trunk wood with size of 1 x 1 x 1 cm3 and ratio (w/v) of 1:10 could immobilize 87.08±2.05% of P. stuartii cells and produce the highest N-acetylglucosamine concentration, which was 238177.78±3153.48 ppm. The highest N-acetylglucosamine production was obtained from first fermentation cycle and decreased over the last three cycles, but still produced high concentration of N-acetylglucosamine. Therefore, it is possible to perform continuous N-acetylglucosamine production from shrimp shells using P. stuartii cells immobilized in papaya trunk wood.

<p>An increase in corn productivity is not always followed by an increase in farmer income and welfare. The sustainability of farms must be supported by its economic viability including the marketing aspect. This study aimed to analyze the marketing of corn in Sigi Regency, Central Sulawesi Province. This research applied qualitative and quantitative methods. Marketing channel and marketing margin were analyzed descriptively, while farmer share was analyzed quantitatively using variance analysis (ANOVA). The results have shown three types of corn marketing channels, namely: 1) channel I, consisting of farmers-consumers, 2) channel II, covering farmers-collectors, traders-retailers and traders-consumers and 3) channel III, including farmers-collectors and traders- feed industries. Channel II has the highest marketing margin, followed by channel III and I, respectively. The intermediaries determine marketing costs that affect marketing margin and farmers’ shares. Channel I has the highest farmers’ shares, followed by channel III and channel II, respectively. The results of the significant difference test have revealed a difference in farmers’ shares in the marketing channels; and hence, the choice of marketing channel significantly determines the farmers’ shares. Therefore, farmers should shorten the marketing chain and strengthen their bargaining position by activating groups. Meanwhile, the government can play an active role so that farmers can have an access to strengthening capital and marketing.</p>

<p>Climate change causes dry and rainy seasons to shift. Hydrology also shows that the number of rainwater changes with the uncertainty of its potential occurrence. In catfish farming and hydroponic farming, ensuring water availability is important for the sustainability of the project. Existing research is about managing rainwater, which can help partially supply water for both projects' benefit. The research location is in Jeron Village, Nogosari District, Boyolali Regency. Boyolali Regency is a 22 % residential area of the total area. It means 570 m<sup>3</sup> potential storage. However, the result shows that only 17% of the roof area can collect rainfall for residential houses. In this study's residential case example, 17% of the roof area gives 97.8 m<sup>3</sup> / year. The problem is that currently, there is no Rain Water Harvesting (RWH). A system capable of supporting the water supply. Using RWH provides a benefit based on the potential supply. This study highlights the potential benefits of using RWH. This pool yields a profit of up to (Indonesian Rupiah) IDR. 36,643,718 / month or IDR. 439,724.61 / year, with a probability of 80%. It means that in 5 years, it failed once. Moreover, water needs can supply from RWH.</p>
Mini Special Issue on Tsunami Numerical Modeling Benchmarks – Challenges of Tsunami Modeling Hackathon –
Authors: Koshimura Shunichi 
Published: September 2021

Numerical simulation and modeling became an essential technology in tsunami research and disaster management. Various numerical models were proposed and utilized for the development of tsunami risk assessment, inundation maps, and evacuation plans. The model verification and validation standards would be crucial to ensure sufficient reliability of tsunami risk assessment, inundation maps, as well as a consistency among various efforts. Common approach to ensure sufficient accuracy and reliability of numerical modeling is developing benchmark problems of hydraulic experiments and to use them for numerical model’s verification and validation.
To satisfy this requirement, “Tsunami Modeling Hackathon” was held in September 2020 to organize new benchmark problems in numerical modeling of tsunamis and to improve their reliability and accuracy. Hackathon is an intensive-gathering event of computer programmers and others involved in software development to create outcomes by the end of the event. This event was organized by Prof. Tomoyuki Takahashi of Kansai University and his colleagues, who led the tsunami research subcommittee in Japan Society of Civil Engineers (JSCE).
Tsunami modeling hackathon, in which about 23 teams and 162 researchers joined, included experiment and modeling teams in seven benchmark problems: urban tsunami inundation, landslide tsunami, tsunami loading on seawalls and coastal structures, sediment transport, drift of floating objects. The modeling groups performed the blind tests to cross-validate and interpret the results of their simulations in seven benchmark problems given by the experiment groups and discussed the improvement.
This special issue reports the outcomes of the tsunami modeling hackathon, and includes six papers (five in this issue, one in the regular issue). We hope this issue will provide useful insights for tsunami modelers and contribute to establishing a standardized way to ensure that various tsunami numerical models would be validated through the benchmark problems.

Abstract
Background

With the life expectance prolonging, more cancer patients occurred spinal metastases. To evaluate the impact of histologies on outcomes of spinal metastases treated with stereotactic body radiotherapy (SBRT) and identify the correlated prognostic factors.
Methods

The authors retrospectively reviewed the records of all patients who underwent SBRT with no prior radiation for spinal metastases between October 2015 and October 2020 at Sun Yat-sen University Cancer Center. Propensity score matching (PSM) was applied to balance the distribution of related baseline characteristics. The endpoints included overall survival (OS), local control (LC), pain relief, and time to pain relief.
Results

A total of 202 consecutive patients with 345 spinal metastases were treated with a median follow-up time of 16.02 months (range, 0.73–57.90 months). The 1- and 2-year OS rates were 57% and 50%, respectively. The median survival was 35.63 months. A higher Karnofsky Performance Scale (KPS) score at consult predicted for better OS (P = 0.020). The presence of pain at enrollment assessed by the Brief Pain Inventory (BPI) predicted for worse OS (P = 0.038). The 1-year LC rate was 92.0%. The pain relief rate was 76.30% (103/135 patients). Younger age was identified to be prognostic for better pain relief (P = 0.037). In the univariate and multivariate analysis, no variable was independently associated with time to pain relief. As for toxicity, no Grade ≥ 3 toxicity was observed.
Conclusions

SBRT is feasible and appears to be an effective treatment paradigm for patients with spinal metastases, with limited accepted toxicities.

Abstract
Assembling cellulose nanocrystals (CNCs) can induce solid-state photoluminescence based on Stokes scattering. Such photoluminescence is free of photo-quenching and should have great potential in optical materials, whereas poor flexibility of assembled CNC arrays limits its applications. Here, a co-assembly of binary components including 1D nanoparticles and long-chain polymers had been explored to introduce the uniaxial CNC arrays into a transparent poly (vinyl alcohol) (PVA) membrane, which enhanced the mechanical properties, especially the stretchable property. Besides, the CNC assembly was controlled by adjusting the volume ratio between CNC and PVA. The result indicated that co-assembly with PVA could improve the uniaxial orientation of assembled CNC arrays, which played a crucial role in enhancing the emission quantum-efficiency (EQE) of CNC. Stretching the PVA/CNC membrane could furthermore induce an enhancement in EQE together with a gradual shift in emission wavelength. The mechanism study on that stimulation-response suggested that the enhancement and shift came from the change in the uniaxial orientation degree and periodicity of the CNC assembly, respectively. Since the stimulation-responsive enhancement in EQE (from ca. 40% to ca. 60%) can even be observed by naked eyes, we believe such cellulose-based materials can be widely used in optical sensors.

Abstract
BackgroundAs commercial low-dose atropine eye-drops for myopia progression control are available in some countries, in-house preparation by diluting the 0.1% atropine eye-drop with sterile water or normal saline has been a common practice. Atropine injection is readily available and could be a more feasible alternative.ObjectiveTo assess the properties of the in-house low-dose atropine eye-drops prepared by diluting the atropine injection in two solvents and tested in two temperature conditions.MethodThe 0.01% atropine eye-drops (15ml) were prepared by diluting atropine sulfate injection with normal saline and lubricant eye-drops and stored at room temperature and in a refrigerator. All samples were daily dropped for 12 weeks to mimic real-life use, one of which was assessed every two weeks for the biological contamination and chemical properties. The active substance was compared with freshly prepared samples at the 12th week.ResultsThe 0.01% atropine eye-drops contains no bacteria, fungi, or particulate matter. The levels of atropine sulfate on all samples were comparable to the freshly prepared samples at the 12th week, regardless of the solvents used or storage conditions.ConclusionThe low-dose atropine eye-drops prepared from readily available atropine sulfate injection at healthcare facilities could be alternative to commercial products.

Abstract
Purpose: To evaluate the functions about the pre-treatment dose verification and, the in vivo dose verification for the commercial software EDose system based on Electronic Portal Imaging Device (EPID) retrospectively and establish the action limit level. Methods: The results of pre-treatment dose verification were compared with 2D array Seven29 and 3Dmap for 50 randomly selected IMRT plans of different lesions. A retrospective analysis was conducted for 287 radiotherapy plans using the EDose in pre-treatment dose verification, including 53 IMRT and 247 RapidArc plans, to establish the action limit level with statistical significance evaluation. 28 head and neck patients with different lesions were selected randomly for studying 3D online dose verification preliminary.Results: For pre-treatment dose verification, 50 plans’ average γ passing rates of the 3%/3mm criterion were > 98% for EDose, Seven29, 3Dmap, and 3%/2mm, 2%/2mm criteria were > 95%, 90%. The average γmean of the three verification methods were similar for the 3%/3mm criterion (0.35, 0.38, 0.35). Based on the 287 patients’ clinical data, the average γ passing rate was 97.5%, and the recommend clinical action level was established at 92% with a 95% confidence limit. The in vivo results showed that the γ pass rate had a decreasing trend as the 33 treatment fractions progressed. The γ passing rates means±SD of the first fraction was (91.92±3.31)% while the 33th fraction was (85.73±8.75)%. In addition, the standard deviation between the TPS calculations and the EDose measurement results indicated a higher value of the thirty-third treatment for PTVs and organ at risk compared to the first treatment.Conclusions: This study demonstrated that the EDose system is an accurate, efficient method for quality assurance of patient’ radiotherapy plans with remarkable consistency of treatment planning system (TPS).

Authors: Özgür Armağan , An Isa 
Published: September 2021

Abstract
Purpose: To assess choroidal thickness in patients with lipoid proteinosis versus healthy subjects using enhanced depth imaging optical coherence tomography. Methods: 40 eyes of 20 patients and the same number of age and sex-matched healthy individuals were enrolled. Comprehensive ocular examinations including measurement of best-corrected visual acuity, spherical equivalent values of refractive errors, and axial length were performed. Choroidal thickness at three points (subfoveal, 500 µm nasal and temporal regions) were measured. Results: The mean age was 15,68 ± 5,98 years in the patient group and 16,48 ± 5,69 years in the control group. Mean choroidal thickness was statistically significantly thicker at each point in patients with lipoid proteinosis compared to the healthy controls: subfoveal, temporal and nasal choroidal thickness measurements were 414,13 ± 53.88, 359.97 ± 64.75, 322.10 ± 56.74 in the study group; 341.60 ± 42.01, 329.55 ± 41.30, 295.44 ± 43.07 in the control group, respectively ( P < 0.05). Conclusion: Patients with lipoid proteinosis have thicker choroid compared to control eyes. Hyalin deposition and ensuing potential inflammation in the disease process may explain this finding.
Understanding the Needs of People With Rare Dementias and Recommendations for Improving Post-diagnostic Care: ‘There Is No Such Thing as One Size Fits All’
Authors: Giebel Clarissa , Cannon Jacqueline , Smith Sandra , Pearson Anna 
Published: September 2021

Abstract
People with rare dementias such as Lewy Body dementia show different symptoms to those with Alzheimer’s dementia. Due to the large proportion of people with Alzheimer’s dementia, most services are designed to support their needs and often neglect those of people with rarer dementias. The aim of this study was to understand the needs of people with rare dementias and their families to develop targeted support. Two care professional focus groups were held in the North West of England. Focus groups lasted up to 60 minutes and were subsequently transcribed and analysed via thematic analysis. One former carer for her husband with a rare dementia was an active member of the project team and helped design the interview schedule, interpret and disseminate the findings. 18 dementia care professionals took part. Thematic analysis generated six themes: (1) Complex needs unsupported; (2) Reluctance to approach services; (3) Lack of service adaptation to both people living with dementia and carers; (4) Lack of communication between service providers; (5) Environment of service provision; (6) Funding issues. As opposed to suggesting new types of social activities, focus groups identified significant barriers in approaching and using post-diagnostic for those affected by a rare dementia, as well as inequalities in access to care services. There are various personal and service barriers for people with rarer dementias and unpaid carers to accessing and using post-diagnostic services. Future implementation work needs to adapt services and identify ways in which to overcome barriers in approaching services.
