Published: May 2024

Background

Digital patient-centered interventions may be important tools for improving and promoting social interaction, health, and well-being among older adults. In this regard, we developed a mobile app called DigiAdherence for an older adult population, which consisted of easy-to-access short videos and messages, to improve health-related knowledge among them and prevent common health conditions, such as falls, polypharmacy, treatment adherence, nutritional problems, and physical inactivity.

Objective

This study aimed to assess the usability and utility of the DigiAdherence app among Portuguese older adults 65 years or older.

Methods

In this pilot noncontrolled quasi-experimental study, older adults who were patients at the primary health care center in Portimão, Portugal, and owned a smartphone or tablet were recruited. Participants were assessed at baseline, given access to the DigiAdherence app for 1 month, and assessed again immediately after 30 days (first assessment) and 60 days after stopping the use of the app (second assessment). App usability and utility (primary outcomes) were analyzed in the first follow-up assessment using a structured questionnaire with 8 items. In the second follow-up assessment, our focus was on knowledge acquired through the app. Secondary outcomes such as treatment adherence and health-related quality of life were also assessed.

Results

The study included 26 older adults. Most participants rated the different functionalities of the app positively and perceived the app as useful, attractive, and user-friendly (median score of 6 on a 7-point Likert scale). In addition, after follow-up, participants reported having a sense of security and greater knowledge in preventing falls (16/24, 67%) and managing therapies and polypharmacy (16/26, 62%).

Conclusions

The DigiAdherence mobile app was useful and highly accepted by older adults, who developed more confidence regarding health-related knowledge.

Authors: Razavi Moein , Ziyadidegan Samira , Mahmoudzadeh Ahmadreza , Kazeminasab Saber , Baharlouei Elaheh , Janfaza Vahid , Jahromi Reza , Sasangohar Farzan
Published: May 2024

Background

Mental stress and its consequent mental health disorders (MDs) constitute a significant public health issue. With the advent of machine learning (ML), there is potential to harness computational techniques for better understanding and addressing mental stress and MDs. This comprehensive review seeks to elucidate the current ML methodologies used in this domain to pave the way for enhanced detection, prediction, and analysis of mental stress and its subsequent MDs.

Objective

This review aims to investigate the scope of ML methodologies used in the detection, prediction, and analysis of mental stress and its consequent MDs.

Methods

Using a rigorous scoping review process with PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines, this investigation delves into the latest ML algorithms, preprocessing techniques, and data types used in the context of stress and stress-related MDs.

Results

A total of 98 peer-reviewed publications were examined for this review. The findings highlight that support vector machine, neural network, and random forest models consistently exhibited superior accuracy and robustness among all ML algorithms examined. Physiological parameters such as heart rate measurements and skin response are prevalently used as stress predictors due to their rich explanatory information concerning stress and stress-related MDs, as well as the relative ease of data acquisition. The application of dimensionality reduction techniques, including mappings, feature selection, filtering, and noise reduction, is frequently observed as a crucial step preceding the training of ML algorithms.

Conclusions

The synthesis of this review identified significant research gaps and outlines future directions for the field. These encompass areas such as model interpretability, model personalization, the incorporation of naturalistic settings, and real-time processing capabilities for the detection and prediction of stress and stress-related MDs.

BACKGROUND

Retinopathy pf prematurity is the leading preventable cause of childhood blind-ness, timely intravitreal injection of anti-vascular endothelial growth factor is re-quired to prevent retinal detachment with consequent vision impairment and loss. However, anti- vascular endothelial growth factor has been reported to be associated with ROP reactivation. Therefore, prediction of reactivation after treatment is urgent need.

OBJECTIVE

To develop and validate prediction models for reactivation after anti-vascular endothelial growth factor intravitreal injection in infants with retinopathy of prema-turity using multimodal machine learning algorithms.

METHODS

Infants with ROP undergoing anti-vascular endothelial growth factor treatment were recruited from three hospitals, conventional machine learning, deep learning and fusion models were constructed. The areas under the curve, accurancy, sensitivity and specificity were used to show the performances of the prediction models.

RESULTS

239 cases with anti-vascular endothelial growth factor treatment were recruit-ed, including 90 with reactivation and 149 non-reactivation cases. The area under the curve for the conventional machine learning model was 0.806 and 0.805 in the inter-nal and external validation groups, respectively. The average area under the curve, sensitivity, and specificity in the external validation for the deep learning model were 0.787, 0.800 and 0.570, respectively. The specificity, area under the curve, and sensitivity for the fusion model were 0.686, 0.822, and 0.800 in external validation, separately.

CONCLUSIONS

We constructed three prediction models for the reactivation of retinopathy of prematurity, fusion model achieved the best performance. Using this prediction model, we may optimize strategies for treating retinopathy of prematurity infants and developing better screening plans after treatment.
Unilateral Activities in Disputed Maritime Areas and Meaningful Responses
Authors: Xiangjin Luo
Published: May 2024

Unilateral activities conducted in a disputed maritime area pending maritime delimitation are considered to be a violation of the pre-delimitation obligations imposed by Article 74/83(3) of the 1982 United Nations Convention on the Law of the Sea, which may trigger State responsibility. The obligations contained are negotiation in good faith and self-restraint. However, this is not a prohibition of all activities in disputed maritime areas. Through a study of the relevant case law of the international courts and tribunals, this article finds leniency towards unilateral activities in disputed maritime areas, i.e., some exceptions are permitted. In the South China Sea, reaching a final delimitation agreement can be a difficult and long-term task due to competing interests and the numerous countries involved. Facing unilateral activities undertaken in such an area, the appropriate and meaningful responses are significant to safeguard maritime rights and interests.

Authors: Afwadzi Benny , Djalaluddin Ahmad
Published: May 2024

A Sharia-based economy faces problems that take work. Not only is there minimal public knowledge, which has resulted in the assumption of equality between Sharia economics and conventional economics but there has also been a decline in Sharia economics in Indonesia. Not to mention the era of digitalization, which has completely changed Sharia economic practices; based on this, this article examines the development of Sharia-based economy in the digital era. The study is limited to aspects of opportunities, challenges, and obstacles. This article aims to understand the context of Sharia economics and how development must be implemented. Using a qualitative approach with library research method, the authors find that Sharia economics is an economy based on Islam. It must adopt digitalization today. Regarding several Sharia economic opportunities in the digital era, namely the Indonesian community as the largest Muslim community and product promotion in digitalization, the challenges are human resources and cyber security. At the same time, the obstacles are minimal public awareness and technological limitations. These opportunities, challenges, and obstacles have implications for the development of the Sharia economy, which must rely on digital aspects with all their shortcomings.

Authors: Budiastuti Herawati , Rachmawati Anissa Nurul , Agustin Delliana , Paramitha Tifa , Rusdianasari
Published: May 2024

The tofu industry produces liquid waste containing high organic compounds. Organic compounds in liquid waste can threaten aquatic ecosystems if discharged directly into water bodies. One of the most effective wastewater treatment systems is the treatment using Anaerobic Sequencing Batch Reactor (ASBR). Besides being able to reduce the content of organic compounds, ASBR can produce biogas, and its decomposing microorganisms do not flow into the effluent stream. The purpose of this study was to evaluate the performance of ASBR at an effective reactor volume according to the design. This is because the use of ASBR in previous studies had not reached the operational stage and did not use an effective volume reactor. The stages of waste treatment using ASBR include the seeding, acclimatization, and operation stages. Waste treatment took place at room temperature in the reactor with an effective volume of 6 L. The operating parameters tested were MLVSS, COD, BOD, pH, and cumulative biogas volume. The results obtained show that the seeding process took 56 days, acclimatization took 10 days, and the operation lasted for 17 days. The efficiency of reducing COD concentration was 60%, the efficiency of reducing BOD concentration was 35.65%, and the cumulative volume of biogas produced was 24,120 mL at the operating stage. The use of the ASBR system at an effective volume of 6 L resulted in the successful processing of tofu liquid waste.
A highly efficient Cre-based Clostridial workflow for genomic integration and expression of large biosynthetic pathways
Authors: Sanford Patrick A. , Blaby Ian , Yoshikuni Yasuo , Woolston Benjamin
Published: May 2024

Acetogenic Clostridia are obligate anaerobes that have emerged as
promising microbes for the renewable production of biochemicals owing to
their ability to efficiently metabolize sustainable single-carbon
feedstocks. Additionally, Clostridia are increasingly recognized for
their biosynthetic potential, with recent discoveries of diverse
secondary metabolites ranging from antibiotics to pigments to modulators
of the human gut microbiota. Lack of efficient methods for genomic
integration and expression of large heterologous DNA constructs remains
a major challenge in studying biosynthesis in Clostridia and using them
for metabolic engineering applications. To overcome this problem, we
harnessed chassis-independent recombinase-assisted genome engineering
(CRAGE) to develop a workflow for facile integration of large gene
clusters (>10 kB) into the human gut acetogen
Eubacterium limosum. We then integrated a non-ribosomal peptide
synthetase gene cluster from the gut anaerobe Clostridium leptum,
which previously produced no detectable product in traditional
heterologous hosts. Chromosomal expression in E. limosum without
further optimization led to production of phevalin at 2.4 mg/L. These
results further expand the molecular toolkit for a highly tractable
member of the Clostridia, paving the way for sophisticated pathway
engineering efforts, and highlighting the potential of E. limosum
as a Clostridial chassis for exploration of anaerobic natural product
biosynthesis.

Published: May 2024

Potassium-ion batteries (KIBs) represent a promising energy storage
solution owing to the abundance of potassium resources. The efficacy of
KIBs relies significantly on the electrochemical attributes of both
their electrode materials and electrolyte. In the current investigation,
we synthesized a layered compound K2[(VOHPO4)2(C2O4)]·2H2O via a
heterogeneous nucleation approach and assessed its viability as a
cathode material for KIBs. When integrated with a salt-concentrated
electrolyte with oxidation stability over 6 V, the compounds exhibits a
high discharge potential of 4.1 V (vs. K+/K) alongside a reversible
capacity of 106.2 mAh g−1. Furthermore, there is no capacity decay after
500 cycles at 100 mA g−1. This study shows the promise of layered metal
organic frameworks as high-potential materials for KIBs.
Impact of Narcotics Information Management System on Inappropriate Benzodiazepine Receptor Agonist Prescriptions: A Quasi-Experimental Analysis in South Korea
Authors: Son Hye Jin , Je Nam Kyung
Published: May 2024

Background: The South Korean government implemented the Narcotics
Information Management System (NIMS) on 18 May 2018 to manage
benzodiazepine receptor agonists (BzRAs) and narcotics effectively and
establish a reporting mechanism for these drugs. This study assessed the
effects of NIMS on inappropriate use of BzRAs. Methods: Using National
Patient Sample data from 2016 to 2020, we analysed adult outpatients who
were prescribed oral BzRAs. We conducted a time series and segmented
regression analysis using selected indicators to analyse the monthly
variations related to the inappropriate use of these medications.
Results: The study revealed no significant changes in the indicators of
inappropriate BzRA use following the NIMS implementation. Contrary to
expectations, there was a significant increase in the proportion of
patients exceeding Defined Daily Dose (DDD) and in those receiving
concurrent prescriptions of multiple BzRAs, following the implementation
of NIMS. The immediate impact of the COVID-19 pandemic was an increase
in DDD exceedance; however, overall, this did not significantly affect
BzRA use. Conclusion: The introduction of NIMS did not significantly
enhance the management of BzRA misuse. Additional measures, including
continuous monitoring, system improvements, and comprehensive education
for prescribers and patients, are recommended to ensure the appropriate
use of psychotropic medications.
Regulation of Sucrose Synthesis and Export in the Response of Photosynthetic Compensation to Heterogeneous Light
Authors: Huang Si-Rong , Ma Cui-E , Qiu Xi , Du Junbo , Yu Liang , Liu Chunyan , Yang Wen-yu , Sun Xin
Published: May 2024

Photosynthetic compensation is an effective strategy for optimizing
light energy utilization in heterogeneous light (HL). However, it is
often impaired, and the involving mechanisms remain unclear,
particularly in C plants. When maize ( Zea mays
L.) cultivars with different photosynthetic compensation capability were
exposed to HL, P of shaded leaves (S-leaves) decreased
in both cultivars, while the P of unshaded leaves
(US-leaves) increased in RY1210(RY) and decreased in ZD808(ZD). Results
also showed increased SPS level, decreased AGPase level, and reduced
Trehalose-6-phosphate (Tre6P) content in US-leaves of both cultivars,
indicating enhanced flux from triose phosphate (TP) to sucrose synthesis
under HL. In addition, SUTs and SWEETs levels of US-leaves increased in
RY, while they decreased in ZD. This result implies that the sucrose
export from the US-leaves of plants with photosynthetic compensation was
enhanced. In US-leaves of ZD, restricted sucrose export led to increased
sucrose and starch, accompanied by a substantial rise in TST2/
SUT2 and extensive accumulation of sucrose in vacuoles. In
summary, photosynthetic compensation involves enhanced flux from TP to
sucrose synthesis and increased sucrose export in US-leaves. In this
process, Tre6P may function as a systemic signal modulator, regulating
sucrose synthesis in source leaves and phloem loading. The increased
sucrose storage in vacuoles may delay the Tre6P perception of sucrose
levels induced by HL, which ensures the increased flux of sucrose
synthesis.
The Use of Hysteroscopy to Identify and Treat Reproductive Tract Abnormalities in the Mare
Authors: Eaton Sarah
Published: May 2024

Hysteroscopy is a complementary tool to the traditional transrectal
palpation and ultrasonography commonly performed by equine
practitioners. Once mastered, it is a quick and useful diagnostic tool
for the general and targeted evaluation of the endometrium and provides
real time information about potential causes of subfertility. Samples of
intrauterine fluid and the endometrium can be taken via transendoscopic
catheters or infusion pipettes or via the use of traditional endometrial
biopsy forceps. In addition to being a useful diagnostic tool,
treatments can often be performed at the same time the pathologies are
identified, providing mare owners with information and resolution of
problems. With the development of additional technologies, hysteroscopy
allows for optical biopsies to be performed, which will likely increase
in use as the software moves from the research laboratories to clinical
practice. Hysteroscopy is an easily learned, useful clinical skill for
the identification of abnormalities in the mares’ reproductive tract.
Interspecific competition reduces seed dispersal in an annual plant and slows simulated range expansions
Authors: McHugh Erin , Urquhart Carla , Williams Jennifer
Published: May 2024

Understanding the factors influencing how fast populations can spread
across the landscape will be crucial as species ranges shift due to
climate change. While the role of abiotic factors in determining
expansion speed has been well studied in theory and empirical research,
how interspecific interactions such as competition impact speed has
received far less attention. Here, we investigated how seed dispersal
distances change in response to competition and how these changes to
seed distributions impact expansion speed. We dispersed four genotypes
of the annual plant Arabidopsis thaliana with variation in life
history traits into greenhouse mesocosms of either empty habitat or
habitat containing the annual grass competitor, Lolium
multiflorum. We found that competition decreased both mean and maximum
dispersal distance. We then built a simulation model of range expansion
with experimental data from this and a prior experiment to understand
whether competition slows species expansions primarily through
decreasing dispersal or fecundity. We found that competition primarily
slows expansion speed through decreases in dispersal, but that when
competition impacts both dispersal and fecundity, expansions slow more
than with dispersal alone. The genotype with traits associated with
longer distance dispersal was the most affected by competition in both
experimental dispersal and simulations. This research suggests that not
only does competition slow range expansions through decreases in both
fecundity and dispersal, but that there may be consequences for
evolutionary processes at the leading edge.

Published: May 2024

The paper aims at predicting the remaining useful life of highly reliable and
long-life products with multiple and multi-stage characteristics in the
degradation process. Considering the unit-to-unit variability among the
product units, a new bivariate and two-phase Wiener process model with
random effects is established. Schwarz Information Criterion is used to
identify the change points of the degradation model, and the analytical
expressions of life and remaining useful life are given by the concept of
first hitting time. Furthermore, the appropriate Copula function is selected
to describe the correlation between the two quality characteristics based on
Akaike Information Criterion. A bivariate degradation model is established
and the unknown parameters of the model are estimated by Markov Chain Monte
Carlo method. Finally, the applicability and effectiveness of the proposed
method are verified by the comparative analysis of turbine engine.

Vertical and transverse treatment effects of Invisalign First system compared to Hyrax maxillary expanders with fixed appliances in mixed dentition patients
Authors: Moravedje Torbaty Parisa , Suh Heeyeon , Tai Sandra Khong , Baird Marta , Boyd Robert L. , Oh Heesoo
Published: May 2024

Objectives

To compare vertical and transverse changes in mixed dentition patients treated with the Invisalign First System (IFS) to those treated with a banded hyrax expander with fixed appliances (Hyrax) and control groups, and to assess the efficiency rate of dental arch expansion with IFS.

Materials and Methods

The study included 80 mixed dentition patients, with 40 in each group (IFS and Hyrax) and 40 controls from the American Association of Orthodontists Foundation Craniofacial Growth Legacy Collection. Skeletal and dental vertical dimension changes and arch width changes between pretreatment (T1) and posttreatment (T2) were evaluated.

Results

Age at T1, time interval (T1-T2), sex, and Angle class did not significantly differ among the groups. Mandibular plane angle changes showed a similar reduction for the control and IFS groups, with no changes in the Hyrax group. However, the differences among the three groups did not reach statistical significance (P = .06). The Hyrax group showed significantly greater expansion in maxillary intermolar width compared to the IFS group, 4.4 vs 2.5 mm, respectively. The efficiency of maxillary expansion using IFS ranged from 52.3% to 76.87%.

Conclusions

During the mixed dentition stage, no significant changes occurred in vertical dimensions among the control, Hyrax, and IFS groups. Although there was a trend suggesting a greater reduction in mandibular plane angle in the IFS group compared to the Hyrax group, this may not be clinically significant given the less than 1° difference. IFS can be a viable option for addressing mild arch width deficiencies, with a predictable increase in intermolar width of approximately 2.5 mm.

The objective of this research was to determine the relationship between strategic management and the economic and financial situation of micro and small enterprises (MSEs) in the hardware sector of the Jesús María district during the COVID-19 pandemic in the period 2020-2021. A quantitative approach and correlational scope were used, with a sample of 26 MSEs and the data collection technique was a survey. The results showed a very high positive correlation between strategic management and the economic and financial situation, supporting the importance of strategic management in the competitiveness and economic development of MSEs. It was concluded that strategic formulation, strategic execution, and strategic control are also related to the economic and financial situation of MSEs. These conclusions have significant implications for companies in the hardware sector, as they highlight the importance of effective strategic management in times of crisis. The findings support the need to plan, execute, and control strategies to face economic and financial challenges.
Att kuratera en kontext för en förskolepraktik i offentliga rum – En annan direkt demokrati uppstår
Authors: Eriksson Christine
Published: May 2024

Denna artikel intresserar sig för hur förskolan skulle kunna erbjuda barn möjlighet att uttrycka sina angelägenheter om offentliga rum på offentliga platser. Teoretiskt är artikeln baserad på filosofen Isabelle Stengers diskussion kring behovet att skapa en annan vetenskap som aktivt deltar i att skapa ett demokratiskt hållbart samhälle, och på den ANT-inspirerade filosofen Annemarie Mols resonemang om empirisk filosofi i syfte att uppmärksamma hur olika praktiker skapar olika offentliga verkligheter. Artikeln visar hur forskare tillsammans med en liten grupp förskolebarn i åldrarna ett och ett halvt till tre år aktiverar offentliga platser såsom en buss, en tunnelbaneresa och en gång- och cykeltunnel i centrala Stockholm. I dessa empiriska aktiveringar uppstår nya offentliga praktiker som markerar en kollektivt deltagande sångpraktik på bussen, hur en kinestetisk praktik av direkt närvaro uppstår i tunnelbanan och där de förkroppsligade och sensoriska kontaktzonerna etableras genom en annan praktik av att läsa väglinjer. 
ENGLISH ABSTRACT
Curating a Context for a Preschool Practice in Public Spaces – Another Direct Democracy Emerges
This article is interested in how the preschool practice could offer children the opportunity to express their concerns about public spaces in public places. Theoretically, the article is based on the philosopher Isabelle Stengers consideration of creating Another science which participates in creating a democratic sustainable society, and in the ANT-inspired philosopher Annemarie Mol’s reasoning about Empirical philosophy in order to pay attention to how different practices create different public realities. The article shows how a researcher together with a small group of preschool children aged one and a half to three years activate public places such as a bus, the underground metro and a walking and bicycle tunnel in the central of Stockholm, Sweden. In these empirical activations new public practices emerge which demark a collective participating singing practice on the bus, a kinesthetic practice of direct presence emerges in the underground metro and where the embodied and sensorial contact zones are established through another practice of reading road lines.

Maxillofacial injuries, especially palatal fractures, often result from high-energy trauma, posing a challenging treatment. Achieving good occlusion is crucial, particularly when palatal fractures are associated with Le Fort fractures. While tracheostomy has traditionally been the airway management option, submental intubation serves as an alternative. The objective of this report is to illustrate a case of palatal fractures associated with Le Fort fractures in a 12-year-old female following a motorbike accident. She was admitted to dr. Cipto Mangunkusumo Hospital with Le Fort I and II fractures and palatal fractures. The treatment plan included submental intubation, the application of wire and arch bars, and the use of plates and screws. The patient experienced a good recovery without complications. Compared to submental intubation, tracheostomy requires a significantly longer time and often necessitates scar revision. No significant difference was observed in post-operative occlusal stability between intra-arch wire and mini-plate. In conclusion, limited direct comparisons exist between submental intubation, tracheostomy, intra-arch wire, and miniplate for palatal stabilization. Submental intubation is a faster and less complication-prone alternative to tracheostomy in maxillofacial surgical procedures. However, evidence regarding the superiority of intra-arch wire or mini plate for palate stabilization remains inconclusive.

Excessive smartphone use causes the behavior of delaying bedtime and decreasing mindful eating in teenagers. The aim of this research is to find out and explain how much the risk of smartphone addiction plays a role in increasing bed procrastination behavior and decreasing mindful eating in adolescents. There were 192 participants involved in the research with the sampling technique used was convenience sampling. Participant characteristics include teenagers aged 18 – 21 years and have a cut off score for smartphone addiction. Each participant filled out the Smartphone Addiction Scale Short Version for Adolescents, Bedtime Procrastination Scale, and Mindful Eating Questionnaire questionnaires. Data were analyzed using a simple regression method. Based on the results of the regression test, it was found that the risk of smartphone addiction played a 6.1% role in increasing bed procrastination behavior and a 13.3% role in reducing mindful eating behavior. The results of this study also found other factors that play a role in procrastination behavior at bedtime and mindful eating in teenagers besides excessive smartphone use. Therefore, it is hoped that future research will be able to consider and look at other factors besides the risk of smartphone addiction that play a role in bed procrastination and mindful eating.

Abstract.Children's relationships with their siblings encompass a spectrum of experiences, ranging from positive connections to negative interactions. A notable negative facet that can emerge within sibling dynamics is the phenomenon of sibling rivalry. This phenomenon entails the manifestation of competition, jealousy, and animosity among siblings, often arising following the birth of a younger brother or sister.The prevalence of sibling rivalry is associated with adverse outcomes, including heightened anxiety and impaired emotional regulation in children. To address the intricate issue of sibling rivalry, fostering cooperative interactions among siblings has been proposed as a potential solution. This research aims to describe whether the modification of the traditional game "Benthik" from East Java can reduce siblingrivalry in children. Additionally, this study also elucidates how the concept of modifying the Benthik game can mitigate sibling rivalry in children. Employing a quasi-experimental methodology, the study was conducted at SD Negeri 1 Sumberjo, Bojonegoro, and involved 30 children aged 8 to 12, each of whom had at least one sibling. The paired sample t-test analysis results reveal a significant influence ofthe Benthik game on sibling rivalry conditions in children, with a p-value of 0.035 (<0.05) denoting statistical significance, thereby indicating that the modified Benthik game holds promise as an effective intervention for addressing sibling rivalry. In conclusion, the research contributes not only to the realm of addressing sibling dynamics but also to the preservation and utilization of traditional regional gamesamid the pervasive influence of digital engagement.

Until now, there have been puddles on several sections of the Grand Depok City Boulevard road, which are located in the Sukmajaya and Cilodong Districts. This study aims to review the drainage system at three inundation locations (A, B, and C), which includes layout, runoff discharge, channel design discharge, channel dimensions, culverts, and cost estimation. The results showed that the drainage system was built inadequately, so an outlet channel was needed at location A and culverts at locations A and C. The calculated runoff discharge ranged from 0.16-0.73 m3/second, with a planned channel discharge ranging from 0.38-1.10 m3/sec. With this discharge value, it is necessary to deepen the canal at location A, which was originally 0.5 m to 0.7 m, and to reduce the slope of the canal bottom at location B, which was originally 3% to 2%. The culverts required at location A are 18.5 m long and 0.6 m in diameter, and there are 39 at location C, each 8 m long and 0.2 m in diameter. The estimated total cost is IDR 155,492,000. Construction of canals and culverts should use precast concrete materials and be done at night. Keywords: Reviewing, Roadside channel, Runoff.

There is increasing interest in Finland to cultivate maize for silage, although the climatic conditions are in the borderline for maize due to the short and cool growing season. This may result in an immature crop that differs from typical maize for ensiling by having low dry matter (DM) and starch concentrations. We evaluated the preservation characteristics of forage maize during 2019 and 2020 harvested in Helsinki, Finland, at two stages of maturity. The DM concentration of the crops ranged from 230 to 360 g kg-1, and starch concentration from 179 to 283 g kg-1 DM. The crops were ensiled in laboratory scale using four different chemical organic acid based additives or a heterofermentative lactic acid bacteria inoculant. A control silage without additive treatment was also included. All silages were well fermented with low pH (average 3.75) and proportion of ammonia N in total N (average 47 g kg-1). Formic acid based additives restricted silage fermentation and most chemical additives improved the aerobic stability of maize silages compared to the control and inoculant treated silages that, under the conditions of the current study, did not differ from each other.
