Authors: Cruz Irwin
Published: April 2022

Growth in exports along extensive margins has been observed during periods of trade liberalization. A rise in new goods margins is important for developing countries as this is a sign of increasing productivity of local firms and a move from overdependence on a small basket of goods. Adapting the methodology of Kehoe and Rul. This study evaluates the changes in the share of total value of the least traded export goods from new ASEAN member countries to Japan before and after the ratification of the ASEAN-Japan FTA. For each of the four countries, a baseline of HS lines of products comprising near 10% of total export value in 2009 was created from the BACI dataset. The analyses show that by 2018 the share of least traded goods to Japan have risen to almost 69% of total export value for Cambodia, 57% for Myanmar and 55% for Laos. For Vietnam, the rise is a modest 29%.

Published: April 2022

Introduction: Ureteric obstruction commonly presents as a urological emergency requiring urgent intervention with urinary diversion. Double J stenting (DJS) is the preferred option to relieve ureteric tract obstruction in our centre. Objective: Our study aims to determine the feasibility and outcomes of DJS by general surgeons and medical officers in a hospital without a resident urologist and to identify the possible predictive factors for successful DJS. Methods: This is a clinical audit of all patients scheduled for DJS in Hospital Bintulu, Sarawak, from January 2017 to March 2020. A total of 57 patients were included. Socio-demographic data and factors predicting success rate, i.e., level of ureteric obstruction and its causes (intrinsic or extrinsic), diagnosis, size and nature of stone(s), degree of hydronephrosis and pre-operative renal profile, were collected. Success rate and postoperative outcomes for all successful cases were evaluated. Bivariate statistical analyses were used to investigate the association of predictive factors with the success rate of DJS. Results: Double J stenting was successful in 63.2% (36 cases) of our total samples of 57 cases. Out of 36 successful cases, 82.1% of the cases were able to return to baseline renal profile within 14 days and 83.3% did not develop fever within 3 days post-operative. The post-operative mean length of stay was 3.16 days and post-operative day 1 mean pain score was 0.72. Causes of obstruction by intrinsic factors, urolithiasis, pre-operative normal serum creatinine (<106 µmol/L) were associated with successful DJS. Conclusion: Double J stenting is feasible and safe to be done in a hospital without a resident urologist with available facilities despite the limitations.

Published: April 2022

This is a short-term longitudinal study of physical, cognitive, psychological and functional outcomes following mild traumatic brain injury (mTBI) in adults, caused by road traffic accident (RTA). Outcome measures were the Montreal Cognitive Assessment (MoCA), the Neuropsychological Assessment Battery Screening Module (S-NAB), the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder 7 (GAD-7) scale. Functional outcomes included returning to working/academia and driving, lifestyle changes, financial claims and litigation status. A total of 285 individuals were diagnosed with mTBI, involving young male motorcyclists (90%): uncomplicated mTBI, n=201; complicated mTBI, n=84. Ethnic distribution consisted of 204 Malays, 58 Indians and 23 Chinese. MoCA detected cognitive deficits (mean=23.11, SD=3.41) within 72 hours of injury. At two weeks, somatic manifestations, physical injuries, cognitive deficits and psychological symptoms were detected. At three months of injury, the language domain was persistently impaired, with a lower score on most cognitive domains in the complicated mTBI category than the uncomplicated mTBI. Psychological and somatic symptoms had improved. Almost 50% of patients had returned to a functional baseline within two weeks of injury and a further 24% within three months. A small proportion of patients made active lifestyle changes (<25%), financial injury claims (38%) and were involved in litigation (11%). In conclusion, mTBI in multi-ethnic Malaysia has multifaceted deficits and outcomes. Early management of symptoms may promote maximum recovery.

Authors: Park Jisung , Kim Jinwhan
Published: April 2022

Optical and acoustic stereo imaging has great potential for the precise
and consistent localization of intervention underwater robots; however,
it is still being explored due to its sensing limitations and various
technical challenges. This study presents a novel localization method by
combining an inertial navigation system and an optical and acoustic
stereo imaging system. As a strategy for localization correction
relative to underwater structures, the robot’s pose is estimated based
on a single acoustic image using a sonar simulator for mid-range
localization, and a robust visual tracking using a 3-D wireframe model
is employed for high-precision localization near the target structures.
The performance of the proposed technique was demonstrated through
experimental validation using real data obtained from a test tank.

Published: April 2022

Background. Pazopanib is an oral angiogenesis inhibitor approved to
treat soft tissue sarcoma (STS) but associated with large interpatient
pharmacokinetic (PK) variability and narrow therapeutic index. In order
to improve its clinical use, this study aimed to define specific
threshold of pazopanib trough concentration (Cmin) associated with
better progression free survival in STS patients. Methods. In this
observational study, pazopanib Cmin was monitored over the treatment
course. For the primary endpoint, the 3-month PFS in STS was analyzed
with logistic regression. Secondary, we performed exposure–overall
survival (OS) in STS (Cox model plus Kaplan–Meier analysis/ log-rank
test) and exposure-toxicity analyses. Results. One hundred eighteen
patients (95 STS and 23 BS) were eligible for PK/PD assessment. In
multivariable analysis, pazopanib Cmin < 27 mg/L was
independently associated with a risk of progression at 3 months (OR
4.21, 95% CI [1.47-12.12], p = 0.008). OS was not statistically
longer between patients with Cmin > 27 mg/L and those with
Cmin < 27 mg/L (log-rank p = 0.07). A higher average of PAZ
Cmin over the first 3 months of treatment was associated with a higher
risk of grades 3-4 toxicities (40.0 vs 30.5 mg/L (OR 1.05, IC95
[1.01-1.09], p = 0.01) Conclusion. Pazopanib Cmin ≥ 27 mg/L was
independently associated with improved 3-month PFS in a large cohort of
STS patients. Pharmacokinetically-guided dosing could be helpful to
optimize clinical management of STS patients in daily clinical practice.
Modelling of crack path in layered architectures composed of dissimilar materials
Authors: Lu Songsong , Liu Binchao , Reed Philippa , Cook Richard , Zhang Yi
Published: April 2022

In order to make full use of the potential fatigue crack growth
resistance provided by layered architectures, a validated crack path
simulation algorithm for crack propagation through different elements of
the layered architectures was established. The crack path approaching a
material interface was predicted by using the maximum tangential strain
(MTSN) criterion and the crack behaviour at the interface was simulated
by a developed two-step method (a modified stress-and-energy-based
cohesive zone method considering the change in direction of an interface
penetrating crack). The crack path simulation by using this algorithm in
layered example architectures indicates: 1) there are two criteria zones
for the transition between crack deflection and penetration in terms of
the relationship between interfacial strength and toughness; 2) the
likelihood of a crack deflecting out of the interface will increase with
the propagation of an interfacial crack and 3) the architecture
difference which affects shielding or anti-shielding behaviour has a
significant effect on crack deflection or penetration events.

Published: April 2022

To promote energy-saving potentials of the energy recovery unit under all-year conditions, a composite system combining pump-driven loop heat pipe with heat pump was firstly proposed, and the mathematical models were established. The operating characteristics of the composite system were studied in the whole year and compared with the traditional heat pump heat recovery system. The results show that the heating capacity of the composite system is in line with the heating load in winter. Compared with the traditional heat pump system, the composite system has higher energy efficiency ratio and lower deviation degree of temperature effectiveness in the whole year. The heat pump composite pump-driven loop heat pipe heat recovery system is generally superior to similar system reported in literatures, which indicates that it can replace heat pump system in buildings ventilation.

Estimation of pollutant dispersion around a building within non-isothermal boundary-layer using detached eddy simulation
Authors: Valger Svetlana
Published: April 2022

The paper presents the numerical results of modelling pollutant transport from a low source behind a bluff-body imitating a building within a non-isothermal boundary-layer. The main goal of the study is to estimate the tracer gas dispersion in a complex turbulent separated flow behind a building in the presence of interference of the atmospheric boundary-layer and local flows. In the first part of the study we compare numerical approaches URANS and IDDES for turbulent flow prediction on a configuration for which experimental data are available. It is shown that detached eddy simulation approach predicts correctly the main separated flow features and demonstrates a reliable correlation with the experimental data on mean velocity, pollutant concentration and temperature fields. In the second part of the study, the influence of unstable thermal stratified flow on the tracer gas transport around a building is analyzed using IDDES method. The unstable thermal flow regime considered in the study affects the distribution of the pollutant concentration in the re-circulation zone behind the building. The presence of additional buoyancy effects leads to an increase in the gas concentration on the leeward wall of the body and gas transport from a ground region to a height greater than in the case with the neutral boundary-layer.

Published: April 2022

Studying the oil-natural-air-natural (ONAN) transformer?s temperature field distribution characteristics and hot spot temperature rise during operation is a key step to evaluate the thermal insulation life of this type of transformer. Firstly, considering the transverse oil passages between the windings and the guiding effect of the oil baffle on the oil flow, this paper takes 35 kV ONAN transformer windings as the research object, which establishes the corresponding electromagnetic-thermal-fluid coupling model and uses the finite element method to calculate the overall distribution of the internal winding temperature field. The calculation results show that when the ONAN transformer reaches thermal equilibrium, the axial temperature distribution of the windings is extremely uneven due to the influence of the transformer oil flow rate, whose difference between both ends is as high as 17.4?. However, the existence of the oil baffle increases the flow velocity of the inter-turn transverse oil passage to 12 times of the original. Affected by this, the oil temperature difference between the two ends of the oil baffle is as high as 2.42?. Secondly, this paper conducted a short-circuit temperature rise test on the test prototype, and selected the different axial heights (18%, 72%, 96%, etc.) of the windings on both sides of the transformer as the characteristic sample points for embedding temperature measurement fiber for real-time temperature monitoring. After comparison, it is found that the simulation calculation is basically consistent with experiment data, and the relative error of the two is less than 3.3%.
Thermal aging management for electricity distribution networks: FEM-based qualification of underground power cables
Authors: Klimenta Jelena , Panic Marija , Stojanovic Miodrag , Klimenta Dardan , Milovanovic Milos , Perovic Bojan
Published: April 2022

It is well-known that there is no PLAN-DO-CHECK-ACT (PDCA) approach that is used by electricity distribution network operators and asset managers of power cable systems. Accordingly, this paper proposes a novel application of the PDCA approach to thermal aging management of underground power cables in electricity distribution networks. Another novelty of the proposed approach is that the finite element method (FEM) is used in combination with the traditional Arrhenius model to calculate the unknown temperature of cable conductors under service conditions. In particular, this means that the FEM-based Arrhenius model can involve the effects of other heat sources, wind, solar irradiation, etc., in procedures for qualification of underground power cables. The Arrhenius model is applied to an actual hot spot of a 110 kV underground cable line of most importance to reliable operation of the electricity distribution network of the city of Belgrade. In the hot spot, the 110 kV cable line is installed in parallel with the group of 35 kV cables and crosses an underground heating pipe-line. The proposed approach is successfully validated using the existing experimental data on cross-linked polyethylene insulation. Finally, it is found that the hot spot effect can shorten the expected total service lifespan of the 110 kV cables in the hot spot area by 36.84%, as well as that the largest consumption of total thermal lifespan occurs in the presence of all the existing thermal effects.

Introduction. Schwannoma, also known as neurilemmoma, is a rare but one of the most common tumors of the peripheral nerves. It originates from Schwann cells of the peripheral nerve sheaths. Schwannoma mostly occurs in adults between 20 to 70 years of age. The regions where the tumor most commonly occurs are the head and neck, but it can occur almost anywhere in the body or the organs. Schwannomas are usually up to 2.5 cm in size but may grow to 4?5 cm. In this study, the rare case of large schwannoma of the median nerve in the distal part of the forearm is presented. Case report. A 46-year-old male patient was referred to a plastic surgeon with a diagnosis of lipoma on the anterior side of the distal third of the left forearm. Ultra-sound and magnetic resonance imaging were done, and the surgery was performed after that. An encapsulated tumor of the median nerve was found, and the tumor was completely removed without nerve damage. Histological analysis showed a benign schwannoma of cellular type and biphasic shape. In the postoperative course, there was transient paresthesia. One year after surgery, no tumor recurrence nor neurological deficit was recorded. Conclusion. Schwannoma is the most common benign tumor of peripheral nerves. Schwannomas over 5 cm in size are extremely rare. Appropriate physical examination, pre-operative imaging studies, and histological verification are required for the final diagnosis. The method of choice in treating large schwannomas is complete surgical excision.

Published: April 2022

OBJECTIVE

Reportedly, two-thirds of the
patients who were positive for diabetes during screening failed to attend a
follow-up visit for diabetes care in Japan. We aimed to develop a machine
learning model for predicting people’s failure to attend a follow-up visit.

RESEARCH DESIGN AND METHODS

We conducted a retrospective cohort
study of adults with newly screened diabetes at a national screening program
using a large Japanese insurance claims database (JMDC, Tokyo, Japan). We
defined failure to attend a follow-up visit for diabetes care as no physician
consultation during the six months after the screening. The candidate
predictors were patient demographics, comorbidities, and medication history. In
the training set (randomly selected 80% of the sample), we developed two models
(previously reported logistic regression model and Lasso regression model). In
the test set (remaining 20%), prediction performance was examined.

RESULTS

We identified 10,645 patients,
including 5,450 patients who failed to attend follow-up visits for diabetes
care. The Lasso regression model using four predictors had a better
discrimination ability than the previously reported logistic regression model
using 13 predictors (C-statistic: 0.71 [95% confidence interval, 0.69–0.73] vs.
0.67 [0.65–0.69]; p <0.001). The four selected predictors in the Lasso regression
model were lower frequency of physician visits in the previous year, lower
HbA1c levels, and negative history of anti-dyslipidemic or anti-hypertensive
treatment.

CONCLUSIONS

The developed machine learning model
using four predictors had a good predictive ability to identify patients who
failed to attend a follow-up visit for diabetes care after a screening program.

Banana is a fruit plant that is widely produced in Indonesia. Unfortunately, this plant is very susceptible to diseases which can reduce the quality and quantity of the crop. This paper proposes disease detection in banana plants using a thermal camera. The detection is carried out using image processing techniques with multilevel thresholding methods. The image is captured using a thermal camera, then the image is preprocessed to suit what is desired. After that, so that the position is the same as the image taken using a digital camera, the image produced by the thermal camera is carried out by an image registration process. The image processing result is compared with the ground truth image obtained from a digital camera to determine the effectiveness of the proposed method. The effectiveness of the proposed method is measured using the parameters Recall, Precision, F-measure, and Accuracy. The effectiveness of the proposed method is quite effective because it produces parameter values above 80%, namely the recall value of 86,59%, the Precision of 99,1%, the F-measure of 92%, and the accuracy of 89,78%.

Excessive use of pesticides confers several ecological and environmental consequences. In this research, we evaluated arthropod occurrence on shallot crops in Palu Valley, Central Sulawesi as an impact of pesticide application in different frequencies. Almost all farmers used synthetic pesticides for controlling pests and diseases where 46.7%, 43.3%, 10.0% of them applied in high, moderate, and low frequency, respectively. By comparing to the last application, the first reduced arthropod diversity index, evenness index, and abundance by 13.8%, 6.7%, and 70.6%, while the second by 7.3%, 2.3%, and 33.5%, respectively. Analysis of the dynamic abundance of pests and natural enemies in seven weeks observation indicated that the pests abundance at low and moderate levels was no different. Whereas predator abundance at low frequency was significantly different with moderate and high rate and between the last two not distinct and the presence of parasitoids was not observed at all, it means the natural enemies were susceptible to pesticides. These data showed the negative impact of pesticides application to arthropods including pests resistance and natural enemies lost; therefore it is necessary to minimize the use of pesticides and integrated pests.

The aim of this study was to assess soybean lines response to infection of Soybean mosaic virus (SMV) under drought stress. The experiment was conducted at the glasshouse in factorial in Randomized Complete Block Design (RCBD) with four replications. The first factor is soybean lines with four soybean lines (GK/PI, GK/M8Grb, W/M, GK/LT) including one susceptible check variety i.e. Anjasmoro. The second factor is drought stress with three levels of soil water content (100, 75, and 50%) field capacity. Seven days after planting (DAP), plants were inoculated with sap from leaves SMV infected soybean. The result showed that drought stress levels had affected the percentage of seed weight loss in GK/L-T than in the Anjasmoro variety. The number of leaves was slowly decreased from 42 to 49 DAP. The level, duration, and frequency of drought stress affected more significant in the inhibition of the seed filling phase. The GK/L-T reaction was not detected in the presence of SMV and also the lowest of Absorbance ELISA Value. The seed yield (t/ha) of GK/L-T that was most superior and the lowest percentage of disease severity under drought stress.

Sugarcane disease disturbance is one of the limiting factors in achieving high productivity. Xylaria sp. has become endemic to sugarcane plantations in Lampung and South Sumatra. The intensity of disease attacks in Indonesia by 25% and 26% can reduce sugar production 12.3 and 15.4%, respectively. Losses due to disease attacks are greater in ratoons because plant cane sugarcane which is attacked by this disease, in ratoon stage, there will be a decrease in the number of shoots. The aim of this study was to obtain isolates of Trichoderma spp. which have antagonistic abilities and have chitinase enzymes so that they are effectively used as biological agents against Xylaria sp. The research method of antagonist test used dual culture test and qualitative test of chitin substrate was used to assess the chitinolytic index of four isolates of Trichoderma spp. The parameters were the inhibition of Trichoderma spp. isolates and the chitinolytic index of the four isolates moreover the value of the chitinase enzyme activity of the selected isolates. Mechanism of antagonist T10 are competition, antibiosis and mycoparasitism. The results showed that the Indonesian Sugar Research Institute (ISRI) T10 isolate could be used as a biological agent against Xylaria sp. The isolate had an inhibitory ability 73.33% with a chitinolytic index value 1.15 and the activity value of the chitinase enzyme crude extraction at a dilution 10-1 was 10.99 units/mL.

The attack of Etiella zinckenella Treitschke on soybean varieties. Soybean is an important food and source of vegetable protein. One of the problems in soybean cultivation in Indonesia is the presence of pests. Integrated pest control (IPM) techniques are increasing along with the awareness of the importance of environmentally friendly sustainable agriculture. One component of IPM is the use of pest-resistant varieties. This study aimed to examine the effect of the soybean varieties against E. zinckenella Treitschke. This research was conducted with a factorial Randomized Completely Block Design (RCBD). The first factor was the type of organic fertilizer with a dose of 10 tons/ha: (P0= control, P1= Bokashi, P2= Vermikompos, P3=cow manure). The second factor is soybean varieties, which were: V1= Dena 2, V2= Dering 1, V3= Deja 2, V4= Deja 1, V5= Devon 1, V6= Devon 2, V7= Derap 1, V8= Derap 2, V9= Devatra 1, V10 = Devatra 2, V11= Detam 1, V12= Detam 2. The results showed that the interaction between varieties and organic fertilizer significantly affected the percentage of pod borer attack. The interaction between P1 x V8 varieties and between P2 x V6 varieties resulted in the highest percentage of pod borer attack and it was significantly different from other interactions, but not significantly different from P3 x V9, P3 x V5, P2 x V11, P1 x V6, P0 x V11, and P0 x V6.
