Published: July 2019

This quantitative comparative research study examines Career Decision-Making Self-Efﬁcacy Scale — Short Form (CDSE-SF-SF) between students who have taken psychologicalassessmenttestsandwhohavenevertakenapsychologicalassessment test, in junior high school students in Central Java Province. This study also measured the difference in Career Decision-Making Self-Efﬁcacy based on gender and the origin of the residency area. Bandura’s Self-Efﬁcacy Theory functions as a theoretical framework, while sampling uses cluster random sampling to obtain students who have taken psychological assessment tests (N = 167), and those who have never followed (N = 186) students. Data collection was carried out through a direct survey consisting of 25-questions Career Decision-Making Self-Efﬁcacy Scale-Short Form (CDSE-SF-SF). T-test data analysis showed that there were signiﬁcant differences between students who had taken IQ test, aptitude test and interests test with those who had never followed. The results is IQ test (t (353) = 2.744, p>0.05), aptitude test (t (353) = 4.327, p>0.05) and, interest test (t (353) = 4.991, p>0.05). This implies that the factors of individualparticipationinpsychologicalassessmenttestscontributesigniﬁcantlytothe Career Decision-Making Self-Efﬁcacy relationship. On the basis of these ﬁndings, it is recommended that career decision making must be improved in schools using career guidance and counseling strategies by involving other parties, one of which is the use of psychological assessment tests.

Total 24 medium to high yielding cattle has been selected for the study, out of which 12 were reared under organic management system and 12 under conventional management system. For cows maintained under organic management system, the animals were fed ad lib quality green fodder grown organically and limited quantity (1.5 to 2.0 kg/cows/day) of concentrate mixture. Production and reproduction performance of animals of both the groups were compared. The results revealed that the reproductive performance was better in cows maintained under organic production management system than their conventional counterparts. The study on milk quality in terms of composition revealed significantly (P less than 0.05) higher fat % of milk, while lower (P less than 0.05) protein % of milk for the cows maintained under organic system as compared to those under conventional system. It can be concluded that the organic management system of dairy cows can be beneficial as depicted by better reproductive efficiency of cows with higher fat % of the milk.
Opióides na Dor Oncológica e o seu Uso em Circunstâncias Particulares: Uma Revisão Narrativa
Authors: Vieira Cláudia , Brás Marta , Fragoso Maria
Published: July 2019

Introdução: A dor é equiparada a quinto sinal vital e deve ser avaliada de forma sistemática em todas as consultas de um paciente com cancro. Os fármacos utilizados na prática oncológica para tratar os doentes com dor crónica moderada a severa incluem analgésicos de ação periférica e central que têm sido abordados em múltiplas diretrizes nacionais e internacionais. No entanto, na prática clínica há que equacionar outros problemas e eventuais comorbilidades, que podem levantar dúvidas no momento da prescrição.Material e Métodos: Fez-se uma revisão da literatura, tentando refletir sobre algumas situações específicas na utilização de opióides, nomeadamente perda da via oral, insuficiência renal (hemodiálise), insuficiência hepática, interações medicamentosas e formulações de ação imediata.Resultados: Os opiáceos naturais (morfina e codeína) e os seus derivados sintéticos e semissintéticos (hidromorfona, oxicodona, fentanilo), o agonista parcial buprenorfina e finalmente o tramadol e tapentadol foram selecionados para esta análise. Os sistemas transdérmicos estão apenas disponíveis para a buprenorfina e o fentanilo. Na insuficiência hepática, o fentanilo foi considerado seguro, mascom exceção da codeína e do tramadol, podem todos ser usados com precaução. Na insuficiência renal, o fentanilo, a hidromorfona e o tapentadol foram considerados seguros. Deve evitar-se a morfina, e os restantes poderão ser usados com precaução. Em pacientes em hemodiálise pode usar-se buprenorfina, fentanilo, hidromorfona e tramadol (em doses até 200 mg/dia).Discussão: O não reconhecimento do impacto das várias situações descritas ao longo deste trabalho, nomeadamente a alteração da biodisponibilidade por perda de via oral, por alteração da farmacocinética e farmacodinâmica dos vários fármacos, quer no contexto da insuficiência de órgão responsável pelo metabolismo ou excreção, quer no contexto das interações farmacológicas, condiciona umnorme risco de subtratamento da dor e consequente impacto em termos de qualidade de vida.Conclusão: A prescrição de opióides é segura e efetiva, mesmo em situações de comorbilidades moderadas a graves como insuficiência renal e hepática e em doentes sem via oral disponível. Neste caso, como quando considerámos as interações farmacológicas, o plano terapêutico deve ser individualizado e o paciente deve ser avaliado regularmente. A seleção inadequada e/ou dose mal ajustada de um fármaco, o não reconhecimento do impacto dos efeitos adversos, frequentemente justificam o mau controlo da dor e a toxicidade excessiva.

Outlier Modeling in Gear Bearing Using Autoencoder for Remaining Useful Life Prediction
Authors: Singh Sunny , Shiv Praneet , Ahmed Atif
Published: July 2019

In this paper, we introduce the Prognostics and Health Management of gear bearing system using autoencoder neural networks. Bearings and gears are the most common mechanical components in rotating machines, and their health conditions are of great concern in practice. This study presents an outlier modeling method for forecasting the gear bearing system failure using the health indicators constructed from mechanical signal processing and modeling. Outlier modeling aims to find patterns in data that are significantly different from what is defined as normal. In the unsupervised outlier modeling setting, prior labels about the anomalousness of data points are not available. In such cases, the most common techniques for scoring data points for outlyingness include distance-based methods density-based methods, and linear methods. The conventional outlier modeling methods have been used for a long time to detect anomalous observations in data. However, this paper shows that autoencoders are a very competitive technique compared to other existing methods. The developed method is demonstrated using the IMS bearing data from NASA Acoustics and Vibration Database.
Evapotranspiration Estimation with UAVs in Agriculture: A Review
Authors: Niu Haoyu , Zhao Tiebiao , Wang Dong , Chen YangQuan
Published: July 2019

Estimating evapotranspiration (ET) has been one of the most important research in agriculture recently because of water scarcity, growing population, and climate change. ET is the sum of evaporation from the soil and transpiration from the crops to the atmosphere. The accurate estimation and mapping of ET are necessary for crop water management. Traditionally, people use weighing lysimeters, Bowen ratio, eddy covariance and many other methods to estimate ET. However, these ET methods are points or location-specific measurements and cannot be extended to a large scale of ET estimation. With the advent of satellites technology, remote sensing images can provide spatially distributed measurements. The satellites multispectral images spatial resolution, however, is in the range of meters, which is often not enough for crops with clumped canopy structure such as trees and vines. And, the timing or frequency of satellites overpass is not always enough to meet the research or water management needs. The Unmanned Aerial Vehicles (UAVs), commonly referred to as drones, can help solve these spatial and temporal challenges. Lightweight cameras and sensors can be mounted on drones and take high-resolution images on a large scale of field. Compared with satellites images, the spatial resolution of UAVs’ images can be as high as 1 cm per pixel. And, people can fly a drone at any time if the weather condition is good. Cloud cover is less of a concern than satellite remote sensing. Both temporal and spatial resolution is highly improved by drones. In this paper, a review of different UAVs based approaches of ET estimations are presented. Different modified models used by UAVs, such as Mapping Evapotranspiration at high Resolution with Internalized Calibration (METRIC), Two-source energy balance (TSEB) model, etc, are also discussed.
BCI Gaze Sensing Method Using Low Jitter Code Modulated VEP
Authors: Kaya Ibrahim , Bohorquez Jorge , Ozdamar Ozcan
Published: July 2019

Visual Evoked Potentials (VEPs) are used in clinical applications in ophthalmology, neurology and extensively in brain computer interface (BCI) research. BCI literature covers steady state VEP (SSVEP) and code modulated VEP (c-VEP) BCIs along with sophisticated methods to improve information transfer rates (ITR). There is a gap of knowledge regarding the VEP adaptation dynamics, physiological generation mechanisms and relation with BCI performance. A simple dual display VEP switch was developed to test signatures elicited by non-isochronic, non-singular, low jitter stimuli at the rates of 10, 32, 50 and 70 reversals per second (rps). Non-isochronic, low-jitter stimulation elicits Quasi-Steady-State VEPs (QSS-VEPs) that are utilized for simultaneous generation of transient VEP and QSS-VEP. QSS-VEP is a special case of c-VEPs and it is assumed that it shares the similar generators of the SSVEPs. Eight subjects were recorded and the performance of the overall system was analyzed by means of Receiver Operating Characteristic (ROC) curves, accuracy plots and ITRs. In summary QSS-VEPs performed better than transient VEPs. It was found that in general 32rps stimulation had the highest ROC area, accuracy and ITRs in general. To investigate the reasons behind this, adaptation dynamics of transient VEPs and QSS-VEPs at all four rates were analyzed and speculated. Moreover, QSS-VEPs were found to lead to higher accuracy by the template matching compared to SSVEPs at 10rps and 32rps.
The influence of the time of single photon transmission of information on the reliability of its reception in a quantum cryptographic communication channel
Authors: Timofeev A. M.
Published: July 2019

Expression for estimating the reliability of information during its transmission through quantum-cryptographic communication channel that contains a dead time photon counter has been obtained in this research. According to the results of mathematical modeling, the dependence of the reliability of the received data on the average time of single photon transmission of information was established. Studies have shown that with an increase in the average time of single photon transmission of information, these dependences grow, reaching saturation. Moreover, with equal parameters with an increase in the average duration of the dead time of a prolonging type, saturation occurs at large values of the average time of a single photon transmission of information.
Acceptability and Appropriateness of a Perinatal Depression Preventive Group Intervention: A Qualitative Analysis
Authors: Diebold Alicia , Segovia Melissa , Johnson Jessica K. , Degillio Aria , Zakieh Dana , Park Hee Jin , Lim Kenneth , Tandon S. Darius
Published: July 2019

Background

Perinatal depression is a prevalent public health concern. Although preventive interventions exist, there is limited literature on the acceptability and appropriateness of these interventions, especially those delivered by paraprofessionals. The Mothers and Babies Program (MB) is a group-based perinatal depression preventive intervention delivered prenatally. A current cluster-randomized controlled trial is examining the acceptability, appropriateness, and effectiveness of MB delivered by mental health professionals compared to paraprofessional staff from home visiting programs.

Methods

The full study enrolled 874 pregnant women. Fifty-three facilitators were trained and delivered the MB intervention. Semi-structured interviews were attempted with a randomly-selected subset of the full sample of pregnant women who received the MB intervention and with all facilitators. Specifically, interviews were conducted with 88 women who received the MB group intervention (45 in the paraprofessional-led arm and 43 in the mental health professional-led arm) and 46 women who facilitated the groups (27 home visiting staff and 19 mental health professionals). Interviews were conducted over the phone in English or Spanish and audio recorded. The recordings were translated into English, as needed, and transcribed. Thematic analysis was conducted using NVIVO to identify key themes related to intervention acceptability and appropriateness. Similarities and differences between study arms were explored.

Results

Clients and facilitators found the MB content and group format acceptable. Challenges included maintaining group attendance, transportation issues, and managing group discussion. Overall, facilitators found the intervention appropriate for pregnant clients with some challenges presented for clients in crisis situations, experiencing housing instability, and with literacy and learning challenges. Participants provided suggestions for improvement, both for the course content and implementation. There were no significant differences found between study arms.

Conclusions

Overall, clients and facilitators enjoyed MB irrespective of study arm, and facilitators found the intervention appropriate for the population. These findings add to the qualitative literature on perinatal depression preventive interventions, specifically those delivered by paraprofessionals.

Background

mHealth, the practice of medicine aided by mobile devices is a growing market. Although the offer on Anesthesia applications (Apps) is quite varied, representative formal assessments on the views of anesthesia practitioners on its use and potential place in daily practice is lacking. This survey aimed thus to cross-assess the Belgian anesthesia population on the use of smartphone Apps and peripherals.

Methods

The survey was exclusively distributed as an online anonymous questionnaire. Sharing took place via hyperlink forwarding by the Belgian Society for Anesthesia and Reanimation (BSAR) and by the Belgian Association for Regional Anesthesia (BARA) to all registered members. The first answer took place on 5 September 2018, the last on 22 January 2019.

Results

349 answers were obtained (26.9% corresponding to trainees, 73.1% to specialists). Anesthesiologists were positively confident that Apps and peripherals could help improve anesthesia care (57.0% and 47.9%, respectively, scored 4 or 5, in a scale from 0 - 5). Anesthesia trainees were significantly more confident that specialists on mobile Apps (72.1% and 51.6%, respectively).

The usefulness of Apps and Peripherals was rated 1 or below (on a 0 to 5 scale) by 9.5% and 14.6% of the subjects. Trainees significantly used mobile apps more than specialists (66.7% vs. 37.4%, respectively).

The preferred category of mobile Apps was dose-calculating applications (39.8%), followed by digital books (21.5%) and Apps for active perioperative monitoring (20.3%).

Conclusions

Belgian Anesthesia practitioners show a significant positive attitude towards smartphone Apps and Peripherals.

Objective: Our study aimed at assessing partner testing and HIV prevalence among individuals tested at an urban tertiary hospital in Sierra Leone.
Results: Of the 3808 clients tested for HIV at Connaught Hospital in Freetown from January to December 2017, 2048(53.8%) were females. Median age was 31 (IQR 24 – 42) years and 2104 (55.3%) were single. While 3014(79.1%) had Provider Initiated Testing and Counselling (PITC), 794 (20.9%) had Client Initiated Testing and Counselling (CITC). HIV test was positive in 925 (24.3%) {CI 22.9 – 25.6, P= 0.00} clients. Of the 17 (0.4%) partners tested for HIV, 9 (52.9%) were positive. PITC yielded more HIV positive cases (760, 25.2%) than CITC (165, 20.8%). Partner testing (CI: 1.45 – 10.20, P=0.007), female sex (CI: 1.32 – 1.80, P=0.000) and PITC (CI: 1.08 – 1.61, p=0.006) were associated with a positive HIV diagnosis. With demonstrated high HIV prevalence and low partner testing, we recommend for stakeholders in the HIV response to address the address the challenges of disclosure and adopt new HIV testing approaches.

Background
The global annual estimate for cryptococcal disease related deaths exceeds 180,000, with three fourth occurring in sub-Saharan Africa. The World Health Organization (WHO) recommends cryptococcal antigen (CrAg) screening in all HIV patients with CD4 count <100/µl. As there is no previous published study on the burden and impact of cryptococcal disease in Sierra Leone, research is needed to inform public health policies. We aimed to establish the seroprevalence and mortality of cryptococcal disease in adults with advanced HIV attending an urban tertiary hospital in Sierra Leone.
Methods: A cross-sectional study design was used to screen consecutive adult (18 years or older) HIV patients at Connaught Hospital in Freetown, Sierra Leone with CD4 count below 100 cells/mm3 from January to April, 2018. Participants received a blood CrAg lateral flow assay (IMMY, Oklahoma, USA). All participants with a positive serum CrAg had lumbar puncture and cerebrospinal fluid (CSF) CrAg assay, and those with cryptococcal diseases had fluconazole monotherapy with eight weeks followed up. Data were entered into Excel and analysed in Stata version 13.0. Proportions, median and interquartile ranges were used to summarise the data. Fisher’s exact test was used to compare categorical variables.
Results
A total of 170 patients, with median age of 36 (IQR 30-43) and median CD4 count of 45 cells/mm3 (IQR 23-63) were screened. At the time of enrolment, 54% were inpatients, 51% were newly diagnosed with HIV, and 56% were either ART-naïve or newly initiated (≤ 30 days). Eight participants had a positive blood CrAg, giving a prevalence of 4.7% (95% CI: 2.4-9.2%). Of those with a positive CrAg, CSF CrAg was positive in five (62.5%). Five (62.5%) CrAg-positive participants died within the first month, while the remaining three were alive and established on ART at eight weeks.
Conclusion: A substantial prevalence of cryptococcal antigenaemia and poor outcome of cryptococcal diseases were demonstrated in our study. The high mortality suggests a need for the HIV programme to formulate and implement policies on screening and pre-emptive fluconazole therapy for all adults with advanced HIV in Sierra Leone, and advocate for affordable access to effective antifungal therapies.
Cystic duct dysplasia after cholecystectomy: a systematic review of the literature

Published: July 2019

Purpose

Approximately 1 to 3.5% of cholecystectomies are found to have incidental dysplasia on histological examination. Cases of positive resection margins on the cystic stump are rare and evidence lack. The aim of this article was to systematically review the literature and to suggest a possible management algorithm.

Methods

We searched PubMed, Cochrane Library and Google Scholar databases by combining “cholecystectomy” AND “dysplasia” AND “cystic” according to PRISMA guidelines. Studies providing information about cystic duct dysplasia with positive resection margin after cholecystectomy were included.

Results

The searches identified 109 articles from PubMed and 4 articles from Cochrane Library and Google Scholar, of which three were eligible. Five were found to have post-operative high-grade dysplasia, one patient had a carcinoma and one had a low-grade dysplasia. Median follow-up was of 10.5 months (range: 0.5 – 26.6 months), no evidence of recurrence was found in patients with dysplasia, while the patient with diagnosis of cholangiocarcinoma died during follow-up.

Conclusions

Patients with positive resection margins for dysplasia after cholecystectomy should be considered for a surgical treatment. The latter depends on several factors related to the patient and the grade of dysplasia itself. Simple cystic duct stump excision has been suggested and it seems to be safe and effective with no evidence of recurrence during follow-up when a R0 resection is achieved. A multidisciplinary approach and a surveillance program should be always taken into account.

Amaranth (Amaranthus sp.) is an important leafy vegetable in Africa where most farmers grow unimproved landraces. Information about amaranth genetic diversity and its adaptation to different environments will help breeders develop improved commercial varieties that meet market requirements. The objectives of this study were to investigate the performances of amaranth entries for vegetable yield across locations and seasons, assess the relative contributions of genetic vs. environmental sources of variation to yield, and cluster locations into mega-environments (MEs) to suggest future test sites. Twenty-six diverse entries were evaluated for vegetable yields in replicated trials at five locations in wet-cool and hot-dry seasons in Tanzania. Season explained the highest proportion (52.1%) of the total sum of squares followed by entries (24.9%) and locations (23.0%). Mean yield across the hot-dry season trials (27.7 t·ha−1) was 47.3% greater than the mean yield across wet-cool season trials (18.8 t·ha−1). Differences among entries in vegetable yield were higher in the hot-dry season than in the wet-cool season, indicating that gain from selection is likely to be greater in the hot-dry season. Most entries performed well in either wet-cool or hot-dry season but a few entries were adapted to both seasons. Two MEs were identified, one characterized by lower altitudes, higher temperatures, and less fertile soils, and a second ME associated with higher altitudes, lower temperatures, and more fertile soils. Each ME may serve as an initial selection site for their respective target environment. Targeting a specific season may give a better chance of finding high-yielding varieties.
A Discrete Limit Theorem for L-Functions of Elliptic Curves
Authors: Garbaliauskienė Virginija , Garbaliauskas Antanas
Published: July 2019

In the paper, we prove the discrete limit theorem in the sense of the weak convergence of probability measures in the space of analytic on DV = {s ∈ C : 1 < σ < 3/2, |t| <  V} functions for L-functions of elliptic curves LE(s). The main statement of the paper is as follows. Let h > 0 be a fixed real number such that exp {2πk/h} is an irrational number for all k∈Z\{0}. Then the probability measure μN(LE(s + imh)∈A), A ∈ B(H(DV)), converges weakly to the measure PLE as N→∞.

Latar Belakang: Stroke merupakan penyebab kematian nomor tiga, setelah

penyakit jantung dan kanker. Stroke juga merupakan penyebab utama kecacatan

fisik maupun mental pada usia lanjut dan produktif. Jumlah penderita stroke di

Indonesia semakin bertambah dan diderita oleh semua lapisan masyarakat.

Keadaan tersebut harus mendapatkan perhatian, sehingga penanganan penderita

stroke diharapkan dilakukan dengan suatu standar yang pasti. Pelayanan yang

dilakukan dengan standar akan menghasilkan mutu pelayanan rumah sakit yang

dapat dipertanggungjawabkan dan pada akhirnya memunculkan kepuasan

pasien.

Tujuan: Tujuan dari penelitian ini adalah membandingkan kepuasan

pasien penderita stroke peserta Jaminan Kesehatan Nasional (JKN) terhadap

mutu pelayanan RS Lestari Raharja Magelang dan RSUD Muntilan Kabupaten

Magelang.

Metode: Penelitian ini merupakan penelitian relational, dengan disain

penelitian kombinasi model concurrent embedded. Instrumen yang digunakan

dalam penelitian ini adalah menggunakan kusioner tertutup yang telah dipakai

oleh peneliti sebelumnya dan pedoman wawancara yang disusun semi struktural,

yaitu berupa pertanyaan-pertanyaan yang digunakan untuk mendapatkan

informasi lebih mendalam tentang faktor kepuasan pasien secara umum maupun

berdasarkan 5 aspek; penampilan fisik, kemampuan pelayanan yang akurat, daya

tanggap, jaminan dan empati kepada pasien/ keluarga pasien penderita stroke di

rumah sakit.

Hasil: Hasil penelitian menunjukkan bahwa 82,4% pasien penderita stroke

di RSUD Muntilan Kabupaten Magelang dan 74,2% pasien penderita stroke di RS

Lestari Raharja yang merupakan peserta JKN menyatakan puas terhadap

pelayanan rumah sakit. Hasil analisa bivariat hubungan jenis rumah sakit

terhadap kepuasan pasien menunjukkan tidak ada hubungan yang signifikan (OR

1,63, 95% CI 0,51-4,90 dan p value 0,33). Hasil analisa multivariat pengaruh jenis

rumah sakit terhadap kepuasan pasien menunjukkan tidak ada hubungan yang

signifikan antara jenis rumah sakit terhadap kepuasan pasien (OR 1,38, 95%CI

0,36-5,28 dan p value 0,63).

Kesimpulan: Penelitian ini menunjukkan tidak ada perbedaan kepuasan

pasien penderita stroke yang dirawat di RS Lestari Raharja dan RSUD Muntilan

Kabupaten Magelang serta tidak ada hubungan antara jenis rumah sakit terhadap

kepuasan pasien.
