PEMBANGUNAN PERTANIAN: SEBUAH KAJIAN PUSTAKA TERSTUKTUR

<p><em>This study aims to examine more deeply about agricultural development. This study uses the systematic literature review method, articles taken from the publications of various publishers using the SCOPUS database and given restrictions on the year of publication only for the last two years or the same as from 2019 to 2021. From the results of this search resulted in 233 views of relevant articles. With this research topic, this figure is obtained from the number of files (.ris) that are exported to Mendeley software. This study explains that agricultural development is currently an integral part of the general public. In agricultural development, it is not only a process or activity of agricultural production but also something that can produce social changes from the scope of values, norms, behavior, institutions, social and so on in order to achieve better economic growth and improve the welfare of farmers and society to become more and more. The limitations of this study are examples of articles presented that differ from the existing conditions in each country so that there is a need for a critical understanding of the government system in the examples of articles that are used as references besides that there needs to be special considerations in determining equations and new findings from articles that are used as reference material to develop the main idea in accordance with the selected topic and title so that the next research needs to understand the main points of the topics that are in accordance with the title and focus on research by adjusting to new things that are to be sought and can be adjusted to the title that is raised.</em></p>

Predicting the Change Impact of Resolving Defects by Leveraging the Topics of Issue Reports in Open Source Software Systems

Upon receiving a new issue report, practitioners start by investigating the defect type, the potential fixing effort needed to resolve the defect and the change impact. Moreover, issue reports contain valuable information, such as, the title, description and severity, and researchers leverage the topics of issue reports as a collective metric portraying similar characteristics of a defect. Nonetheless, none of the existing studies leverage the defect topic, i.e., a semantic cluster of defects of the same nature, such as Performance, GUI, and Database , to estimate the change impact that represents the amount of change needed in terms of code churn and the number of files changed. To this end, in this article, we conduct an empirical study on 298,548 issue reports belonging to three large-scale open-source systems, i.e., Mozilla, Apache, and Eclipse, to estimate the change impact in terms of code churn or the number of files changed while leveraging the topics of issue reports. First, we adopt the Embedded Topic Model (ETM), a state-of-the-art topic modelling algorithm, to identify the topics. Second, we investigate the feasibility of predicting the change impact using the identified topics and other information extracted from the issue reports by building eight prediction models that classify issue reports requiring small or large change impact along two dimensions, i.e., the code churn size and the number of files changed. Our results suggest that XGBoost is the best-performing algorithm for predicting the change impact, with an AUC of 0.84, 0.76, and 0.73 for the code churn and 0.82, 0.71, and 0.73 for the number of files changed metric for Mozilla, Apache, and Eclipse, respectively. Our results also demonstrate that the topics of issue reports improve the recall of the prediction model by up to 45%.

Integrated Approach for Providing Data Security Verification Over Encrypted Cloud Data

The cloud has recently attracted a lot of user attention from both small and large businesses, including those in software, BPO, healthcare, schools, colleges, and many other industries. For data storage and access from remote places linked to one another from a central server with the aid of the internet, all of these organisations attempt to adopt this centralised cloud server. Because all data is stored remotely and only occasionally accessed locally, the confidentiality of data is crucial to cloud service providers. As is common knowledge, no cloud service provider currently offers data privacy through encryption and message digests to enable data authorisation. almost all businesses An untrusted user can query data files of interest by sending encrypted keywords as a search query to the cloud server. Try to search the data in a secure manner over encrypted cloud data. In this dishonest cloud environment, the returned query results may occasionally be correct, incorrect, or partial. As everyone is aware, cloud servers today nearly actively withhold some qualified results in order to conserve computational resources and communication overhead. In this research, we presented and analysed a safe, practical, and fine-grained query results verification mechanism, by which the query user, given an encrypted query results set, not only can confirm the integrity of each data file, but also determines the overall number of qualifying data files, which are not returned if the set is not finished before the decryption procedure. This served as our primary inspiration for creating a brand-new secure verification object for encrypted cloud storage. Here, the short signature key is created using the message digest method MD5, which is also used to confirm the data's authenticity. We tested our proposed model in a variety of ways, and the results demonstrate that it is a useful and effective system

Primary anastomosis and suturing combined with vacuum-assisted abdominal closure in patients with secondary peritonitis due to perforation of the small intestine: a retrospective study

BackgroundIntestinal resection and a proximal stoma is the preferred surgical approach in patients with severe secondary peritonitis due to perforation of the small intestine. However, proximal stomas may result in significant nutritional problems and long-term parenteral nutrition. This study aimed to assess whether primary anastomosis or suturing of small intestine perforation is feasible and safe using the open abdomen principle with vacuum-assisted abdominal closure (VAC).MethodsBetween January 2005 and June 2018, we performed a retrospective chart review of 20 patients (> 18 years) with diffuse faecal peritonitis caused by small intestinal perforation and treated with primary anastomosis/suturing and subsequent open abdomen with VAC.ResultsThe median age was 65 years (range: 23–90 years). Twelve patients were female (60%). Simple suturing of the small intestinal perforation was performed in three cases and intestinal resection with primary anastomosis in 17 cases. Four patients (20%) died within 90-days postoperatively. Leakage occurred in five cases (25%), and three patients developed an enteroatmospheric fistula (15%). Thirteen of 16 patients (83%) who survived were discharged without a stoma. The rest had a permanent stoma.ConclusionsPrimary suturing or resection with anastomosis and open abdomen with VAC in small intestinal perforation with severe faecal peritonitis is associated with a high rate of leakage and enteroatmospheric fistula formation.Trial registrationThe study was approved by the Danish Patient Safety Authority (case number 3-3013-1555/1) and the Danish Data Protection Agency (file number 18/28,404). No funding was received.

SPPUSM: An MS/MS spectra merging strategy for improved low-input and single-cell proteome identification

Single and rare cell analysis provides unique insights into the investigation of biological processes and disease progress by resolving the cellular heterogeneity that is masked by bulk measurements. Although many efforts have been made, the techniques used to measure the proteome in trace amounts of samples or in single cells still lag behind those for DNA and RNA due to the inherent non-amplifiable nature of proteins and the sensitivity limitation of current mass spectrometry. Here, we report an MS/MS spectra merging strategy termed SPPUSM (same precursor-produced unidentified spectra merging) for improved low-input and single-cell proteome data analysis. In this method, all the unidentified MS/MS spectra from multiple test files are first extracted. Then, the corresponding MS/MS spectra produced by the same precursor ion from different files are matched according to their precursor mass and retention time (RT) and are merged into one new spectrum. The newly merged spectra with more fragment ions are next searched against the database to increase the MS/MS spectra identification and proteome coverage. Further improvement can be achieved by increasing the number of test files and spectra to be merged. Up to 18.2% improvement in protein identification was achieved for 1 ng HeLa peptides by SPPUSM. Reliability evaluation by the “entrapment database” strategy using merged spectra from human and E. coli revealed a marginal error rate for the proposed method. For application in single cell proteome (SCP) study, identification enhancement of 28%–61% was achieved for proteins for different SCP data. Furthermore, a lower abundance was found for the SPPUSM-identified peptides, indicating its potential for more sensitive low sample input and SCP studies.

Distributed and Lightweight Software Assurance in Cellular Broadcasting Handshake and Connection Establishment

With developments in OpenRAN and software-defined radio (SDR), the mobile networking implementations for radio and security control are becoming increasingly software-based. We design and build a lightweight and distributed software assurance scheme, which ensures that a wireless user holds the correct software (version/code) for their wireless networking implementations. Our scheme is distributed (to support the distributed and ad hoc networking that does not utilize the networking-backend infrastructure), lightweight (to support the resource-constrained device operations), modular (to support compatibility with the existing mobile networking protocols), and supports broadcasting (as mobile and wireless networking has broadcasting applications). Our scheme is distinct from the remote code attestation in trusted computing, which requires hardwarebased security and real-time challenge-and-response communications with a centralized trusted server, thus making its deployment prohibitive in the distributed and broadcasting-based mobile networking environments. We design our scheme to be prover-specific and incorporate the Merkle tree for the verification efficiency to make it appropriate for a wireless-broadcasting medium with multiple receivers. In addition to the theoretical design and analysis, we implement our scheme to assure srsRAN (a popular open-source software for cellular technology, including 4G and 5G) and provide a concrete implementation and application instance to highlight our scheme’s modularity, backward compatibility to the existing 4G/5G standardized protocol, and broadcasting support. Our scheme implementation incorporates delivering the proof in the srsRAN-implemented 4G/5G cellular handshake and connection establishment in radio resource control (RRC). We conduct experiments using SDR and various processors to demonstrate the lightweight design and its appropriateness for wireless networking applications. Our results show that the number of hash computations for the proof verification grows logarithmically with the number of software code files being assured and that the verification takes three orders of magnitude less time than the proof generation, while the proof generation overhead itself is negligible compared to the software update period.

Semiautomatic Training Load Determination in Endurance Athletes

Background: Despite endurance athletes recording their training data electronically, researchers in sports cardiology rely on questionnaires to quantify training load. This is due to the complexity of quantifying large numbers of training files. We aimed to develop a semiautomatic postprocessing tool to quantify training load in clinical studies. Methods: Training data were collected from two prospective athlete’s heart studies (Master Athlete’s Heart study and Prospective Athlete Heart study). Using in-house developed software, maximal heart rate (MaxHR) and training load were calculated from heart rate monitored during cumulative training sessions. The MaxHR in the lab was compared with the MaxHR in the field. Lucia training impulse score, based on individually based exercise intensity zones, and Edwards training impulse, based on MaxHR in the field, were compared. A questionnaire was used to determine the number of training sessions and training hours per week. Results: Forty-three athletes recorded their training sessions using a chest-worn heart rate monitor and were selected for this analysis. MaxHR in the lab was significantly lower compared with MaxHR in the field (183 ± 12 bpm vs. 188 ± 13 bpm, p < .01), but correlated strongly (r = .81, p < .01) with acceptable limits of agreement (±15.4 bpm). An excellent correlation was found between Lucia training impulse score and Edwards training impulse (r = .92, p < .0001). The quantified number of training sessions and training hours did not correlate with the number of training sessions (r = .20) and training hours (r = −.12) reported by questionnaires. Conclusion: Semiautomatic measurement of training load is feasible in a wide age group. Standard exercise questionnaires are insufficiently accurate in comparison to objective training load quantification.

Synthesis and Study of Optical Properties of Dy3+ Doped Yellow Emitting Fluoroapatite for White -LED Applications

In this article, we report that Ca8BiNa(PO4)6F2 fluorapatites, which were synthesised using a modified Pechini method and were first time doped with Dy3+ ions, are a promising material for yellow emitting phosphor for various optical applications. This fluorapatite has the ability to position activator Dy3+ ions in any of two cationic sites, namely M1 and M2, with distinct symmetries Cs and C3, respectively. After the sample was characterised, it was determined by XRD and Reitveld refinement analysis that it had crystallised into a hexagonal shape and belonged to the space group P63/m, matching the JCPDS file number 96-900-1879 According to the results of the PL analysis carried out by the Hitachi F-7100 spectrofluorophotometer, two emission peaks were obtained: one at 481 nm, which falls under the blue region, and the other at 575 nm, which falls under the bright yellow region. These two emission peaks correspond to the 4F9/2 to 6H15/2 and 4F9/2 to 6H13/2 transitions, respectively (Figure 5b). We suggest that the Ca8BiNa(PO4)6F2: Dy3+ can be employed as an excellent luminescent material with ultraviolet radiation as an excitation source for a variety of optical applications based on its optical properties. White light for WLED applications can be produced by a special phase doping of Dy3+ species in the host material with yellow and blue emission.

Structural and luminescence studies of Eu3+ doped K2BaSr(PO4)2 phosphor

Eu3+ doped K2BaSr(PO4)2 phosphor which gave red emission, was successfully synthesized by using the solid-state reaction method. The X-ray powder diffraction technique determined the crystal structure and the photoluminescence (PL), and thermoluminescence (TL) were also measured. The XRD pattern of prepared K2BaSr(PO4)2 is good matched with the COD CIF File number 00-100-7161. The structure of the phosphor is orthorhombic. The crystallite sizes are evaluated from diffraction peaks using the Scherrer formula. In PL emission, two peaks are found at 592 nm and 614 nm at 395 nm excitation wavelength. The as-developed phosphor can be used in the development of WLEDs.

Prevalence and Visual Consequences of Non-adherent Patients Receiving Anti-vascular Endothelial Growth Factor (VEGF) Injections at King Fahad Specialist Hospital (KFSH), Qassim Region.

Anti-vascular endothelial growth factor (VEGF) injection treatment is a widely utilized therapy for various retinal diseases, including diabetic macular edema (DME). Therefore, the importance of compliance and follow-up should be discussed with the patient. There have been no studies conducted in the Qassim region to estimate the prevalence of patients missing their anti-VEGF appointments. To fulfill this need, we conducted this study to evaluate the compliance rate of patients treated with anti-VEGF injections for DME as well as to determine the visual consequences of the delay in anti-VEGF treatment in the Qassim region. This observational retrospective cohort study was conducted at King Fahad Specialist Hospital (KFSH) in the Qassim region of Saudi Arabia. We extracted all file numbers of patients who were using intravitreal anti-VEGF injections to treat DME. The data were managed and analyzed using the IBM Statistical Package for the Social Sciences (SPSS) software (IBM Corp., Armonk, NY, USA). In the current study, we were able to collect data from 198 patients who received anti-VEGF treatment in the hospital. Among the participants, 57.6% were male, with a mean age of 61.7 years old (standard deviation (SD) = 10.23). Among the patients, we found that the rate of non-adherence to the anti-VEGF injection was 54.5%, and those patients delayed their scheduled doses for more than 56 days. In 47.5% of the patients, delaying or stopping their appointments had no known reason; however, blepharitis was the main reason for delaying or stopping the dose in 27.7% of the patients, followed by endophthalmitis in 18.7% of the patients. There is no significant difference between before and after stopping the treatment, considering visual acuity (VA) or optical coherence tomography (OCT). However, regarding the disease progression, we found that 15 out of the 30 patients had worsened in the OCT after they missed their injections (mean increase in the VA was 6.069 (SD = 97.45), t = -0.278, P = 0.783, and decrease in the OCT was -14.9667 (SD = 133.87, P = 0.454). There is a high rate of patients who missed their appointments for an anti-VEGF injection. This resulted in the worsening of OCT in half of the 30 patients who were enrolled in the visual consequences study, which had a negative impact on treatment and disease progression.

Construction information security management system based on data sharing algorithm

Due to the lack of data security protection, a large number of malicious information leaks, which makes building information security (InfoSec) issues more and more attention. The construction information involves a large number of participants, and the number of construction project files is huge, leading to a huge amount of information. However, traditional network security information protection software is mostly passive, which is difficult to enhance its autonomy. Therefore, this text introduced data sharing algorithm in building InfoSec management. This text proposed an Attribute Based Encryption (ABE) algorithm based on data sharing, which is simple in calculation and strong in encrypting attributes. This algorithm was added to the building InfoSec management system (ISMS) designed in this text, which not only reduces the burden of relevant personnel, but also has flexible control and high security. The experimental results showed that when 10 users logged in to the system, the stability and security of the system designed in this text were 87% and 91% respectively. When 20 users logged in to the system, the system stability and security designed in this text were 89% and 92% respectively. When 80 users logged in to the system, the system stability and security designed in this text were 94% and 95% respectively. It can be found that the stability and security of the system have reached a high level, which can ensure the security of effective management of building information.

Assessment the impact of operator experience on cyclic fatigue resistance in reciprocating and rotary NiTi files: a comparative study between dental students and pediatric dentistry specialists

Introduction: Devices reducing clinical practice time, and which get minimally affected by user experience are invaluable in pediatric dentistry. Additionally, knowing the fracture resistance of different nickel-titanium (NiTi) files for root canal preparation of primary teeth is important for treatment success. Thus, the present study aimed to compare the instrumentation time (IT) and fracture resistance of reciprocating T-endo MUST (TEM) and continuously rotating AF Baby File (ABF) NiTi files according to the use of pediatric dentistry specialists.Methods: According to their clinical experience level, 3 experimental groups (EG)s were formed namely: no experience, 2-years (less-experienced), and 10-years experienced pediatric dentistry specialists' groups. The fourth group was the control group (CG). In each EGs, 10 TEM (25/.06) and 10 ABF 20/.04, and 10 ABF 25/.04 NiTi file systems were used in 20 artificial resin teeth. Instrumentation time was recorded for each tooth. In the CG, the same number of files were not used for instrumentation. The files in all groups were subjected to a dynamic cyclic fatigue test, and the data were analyzed using the Kruskal–Wallis test at 5% significance level.Results: In all groups, TEM files showed a significant higher fatigue resistance as compared to ABF files. However, fatigue resistances were significantly lower in (EG)s both in TEM and ABF compared to (CG)s. The instrumentation time was found to be significantly lower in TEM compared to the ABF. Also, for both file systems, the experience level did not affect the fatigue resistance, and instrumentation time.Discussion: The experience level of the pediatric dentist did not affect the cyclic fatigue resistance of the reciprocating and rotating NiTi files, but the instrumentation time was lower for the reciprocating NiTi files.

Tracking Persons With Vehicles

In order to carry out an exhaustive investigation of the theme, the analysis of the problems was resorted to by referring to certain doctrinal points of view, evaluating and synthesizing some aspects in the field of technique and tactics of the tracking bodies. I used the inductive method as the main method because science uses experience as a means of confirming its conclusions and hypotheses. For the study of the theme, its complexity was taken into account, for which a combination of some classic research methods with some new method,s was preferred. Thus, direct observation was used to underline the importance of the methods/tactics/rules that must be followed so that the mission of tracking people can be a success. Indirect observation was used by appealing to some clear and well-written previous findings in the studied subject. Other methods used throughout the elaboration of the paper include: - the sociological method necessary for the collection, analysis and interpretation of information; - the documentary research undertaken at some police headquarters in order to fully understand the techniques and tactics of the investigative bodies; - the documentary research undertaken at the headquarters of the local police units to reveal the number of files, which were solved with the help of tracking techniques; - indirect research.

Utilisation and optimisation of beta-adrenergic receptor blockers over a 6-month period among chronic heart failure patients with reduced ejection fraction.

Beta-adrenergic receptor blocker (BARB) drugs are a wide range of medicines that are used in various conditions, including chronic heart failure (HF). Several studies have reported a wide-ranging inappropriate use of evidence-based beta-blockers (EBBBs) in chronic HF in both inpatients and outpatients. To assess the utilisation and optimisation of EBBBs among patients with HF who presented with a reduced ejection fraction (HFrEF). A hospital-based retrospective cross-sectional study was carried out at the Adult University Teaching Hospital (AUTH), in Lusaka, Zambia, where patient medical files for the period of 1 July 2018 to 31 July 2021 were reviewed. Patient information, including file number, age, sex, type of BARB and the dose used, was recorded on the developed and validated checklist. Multivariable regression analysis was performed to identify factors associated with utilisation of BARBs. Of the 173 medical records reviewed, BARBs were utilised in 101 (58.4%) patients. Among the patients who utilised BARBs, 96 (95.0%) were taking EBBBs, while the rest (n=5, 5.0 %) were taking atenolol, which is a non-EBBB. Among the patients who were on EBBBs, none of them received the optimal dose. Age ≥65 years (adjusted odds ratio (aOR) 0.3, 95% confidence interval (CI) 0.17 - 0.64), previous hospitalisation (aOR 0.3, 95% CI 0.13 - 0.51) and furosemide dose ≥40 mg (aOR 0.4, 95% CI 0.21 - 0.64) were significantly associated with lower likelihood of BARB utilisation. New York Heart Association (NYHA) class II (aOR 3.4, 95% CI 1.08 - 10.7), NYHA class III (aOR 4.8, 95% CI 1.65 - 13.7) and patients using at least 5 medications (aOR 5.0, 95% CI 2.91 - 8.77) were independent predictors of BARB utilisation. This study showed that 95.0% of chronic HF patients were utilising EBBBs, and none received the optimal dose as recommended in the guidelines. Pharmacotherapy with EBBBs should be optimised among patients with chronic HfrEF, as these drugs reduce both morbidity and mortality.

Analisis Penyebab Terjadinya Penumpukkan Berkas Rekam Medis di Ruangan Filling pada Rumah Sakit X Batam Kota Tahun 2022

Inpatient and outpatient medical record files at X Batam City Hospital have increased the number of medical record files, because every year the number of outpatient and inpatient visits at X Batam City Hospital has increased significantly, so that the medical record file storage area is also narrower too. The purpose of this research is to find out the causes of the accumulation of medical record files in the Filling Room at X Batam City Hospital. The research method used in this study uses a qualitative method by taking data from observations, interviews and documentation. The results of this study indicate that the cause of the accumulation of medical record files is that officers have never participated in medical record training so that the lack of knowledge from medical record officers regarding the storage of medical record files and shelves in the filling room at X Batam City Hospital is not in accordance with the SOP. The medical record file storage system at X Batam City Hospital is placed in one room where the storage system uses a centralized system. Aspects that cause the accumulation of medical record files in the filling room at X Batam City Hospital, namely for the first aspect are medical record officers, the second aspect is infrastructure suggestions and the third aspect is Method.

Multi-MEC collaboration for VR video transmission: Architecture and cache algorithm design

Virtual Reality (VR) is becoming an important use case for 5G wireless networks, and Mobile Edge Computing (MEC) servers are being explored as a way to reduce VR video latency. To address the limited cache space of a single MEC server, this paper proposes dividing geographically close MEC servers into collaborative domains. A new VR video transmission architecture is designed after analyzing video compression mechanisms.The proposed architecture splits the VR video into equal-sized tile files to simplify the cache problem and improve caching efficiency. However, the large number of different tile files presents a challenge. To address this, the paper proposes an optimized k-shortest paths (OKSP) algorithm with a time complexity of O((K⋅M+N)⋅M⋅logN), where K is the number of tiles that all M MEC servers can cache in the collaboration domain and N is the number of tile files. For extremely large-scale data cases, a greedy-based approximation algorithm is also proposed. The numerical results demonstrate the OKSP algorithm’s excellent performance in solving large-scale data, outperforming other caching algorithms in experiments.

RDIMM: Revocable and dynamic identity-based multi-copy data auditing for multi-cloud storage

Multi-copy data possession on multi-cloud storage service provides resource-constrained users with a secure and effective way to process data maintenance. To enable integrity for the outsourced data, numerous multi-copy data auditing schemes for multi-cloud storage have been proposed. Nevertheless, existing solutions suffer from the following limitations: (i) cannot support dynamic data updates; (ii) fail to consider the user revocation feature; (iii) may leak the privacy of user identity. To address these limitations, we propose a new identity-based multi-copy data auditing scheme for multi-cloud storage, termed RDIMM. We introduce a new variant of Merkle Tree to enable fully dynamic data updates, in which all copies of a raw block are kept in the same leaf node. In addition, we design a new key generation strategy and a private key update technique, where the cost of user revocation is independent of the total number of file blocks owned by the revoked user. Moreover, we conduct a comprehensive correctness analysis and security analysis of our proposed RDIMM. In addition, we provide detailed theoretical analysis and experimental simulations, which illustrate the effective functionality and practical performance compared to state-of-the-art works.
