Abstrak: Sistem Informasi Penerimaan Pegawai Di STMIK Pelita Nusantara. Penerimaan pegawai di STMIK Pelita Nusantara masih mengirim berkas langsung ke kantor bidang akademik dalam bentuk hardcopy. Hal ini menjadi kendala mengakibatkan penumpukan berkas dan dalam verifikasi sering terjadi kesalahan. Rekrutmen menggunakan data fisik dalam verifikasi berkas lamaran yang tentunya sangat rentan hilang karena tercampur dengan berkas pelamar. Sistem informasi yang diusulkan memiliki beberapa keunggulan dan perbedaan dari sistem yang sedang berjalan, sistem yang diusulkan secara langsung sehingga lebih mudah digunakan, integritas data terjaga tidak akan memakan waktu yang lama dalam mengolah data, telah disediakan pencetakan laporan-laporan dan fasilitas lainnya yang akan memudahkan user untuk menggunakan sistem ini. Tujuan penelitian antara lain merancang sistem penerimaan pegawai dan mengimplementasikan sistem penerimaan pegawai pada STMIK Pelita Nusantara. Sistem yang dibangun mengimplementasikan tahapan pengembangan software, analisa, design, implementasi sehingga menghasilkan suatu sistem penerimaan pegawai yang meliputi penginputan data pelamar, tes seleksi dan tes wawancara yang lebih terperinci dengan memudahkan user untuk mencari pegawai yang lebih tepat dan akurat diimplementasikan dengan PHP dan My SQL.

Abstrcat: Employee Admission Information System In STMIK Pelita Nusantara. Recruitment of employees at STMIK Pelita Nusantara still sends files directly to the academic office in hardcopy form. This becomes an obstacle in the accumulation of files and in verification errors often occur. Recruitment uses physical data in verifying application files, which of course are very vulnerable to being lost because they are mixed with other applicant files. The proposed information system has several advantages and differences from the current system, the proposed system has been automated so that it is easier to use, maintained data integrity will not take a long time to process data, because it has provided printing reports and other facilities. will make it easier for users to use this system. The research objectives include designing an employee recruitment system and implementing an employee recruitment system at STMIK Pelita Nusantara. The system built implements the stages of software development, analysis, design, implementation so as to produce an employee recruitment system which includes inputting applicant data, selection tests and more detailed interview tests by making it easier for users to find more precise and accurate employees implemented with PHP and My SQL.

Define, measure, analyze, improve, and control, known as DMAIC, is used as research approach. The research begun by describing current state map to identify waste that occurs along the value stream. Followed by identifying activities based on three classifications, namely value added, non-value added, and necessary but non-value-added activities. Once such activities known, cost of poor quality and Sigma level is measured. Fish-bone diagram as well as failure mode and effect analysis are used in order to analyze risk priority number. This study found three wastes namely defect, waiting, and inventory as main focus to eliminate then improve effectiveness along production process.
TEKNIK SMOTE DAN GINI SCORE DALAM KLASIFIKASI KANKER PAYUDARA
Authors: Ramadhan Nur Ghaniaviyanto , Adhinata Faisal Dharma
Published: October 2022

Breast cancer is a malignancy in breast tissue that can originate from the epithelium of the ducts and lobules. WHO says 30% - 50% of cancer cases can be prevented. Breast cancer prevention can be done utilizing screening or early diagnosis. The purpose of the initial diagnosis is that if a lump appears, predictions can be made whether it is classified as malignant or benign. Breast cancer prediction can be done using a dataset containing cancer-related parameters. However, sometimes the dataset used also has problems such as the amount of data is not balanced and the use of irrelevant features. This study aims to improve breast cancer prediction results by balancing the number of data classes and using the rank feature. The method used is SMOTE for imbalanced data and Gini score for rank features. The classification model used is random forest and naïve Bayes. The results obtained by the random forest classification model are superior to Naïve Bayes.
A Thematic Engagement of Literature on Prayer Mountains as Sacred Spaces in Contemporary Ghanaian Christianity
Authors: Okyere Philip Kwadwo
Published: October 2022

Sacred spaces and their attendant pilgrimage attractions seem to be some of the universal and more obvious features of world religions. One of the emerging phenomena within contemporary Ghanaian Christianity is Christians’ pilgrimage to some sacred mountains. Even though scholarship on this phenomenon is gradually bourgeoning within the Ghanaian epistemic context, a thematic engagement of literature on Prayer Mountains (PMs) as sacred spaces in the Ghanaian Christian setting seems to have fallen out of scholars’ grasp. This paper, therefore, employs discourse analysis as a method to elucidate some selected themes. In light of discourse analysis, the paper concludes, among others, that the evolution of the PMs phenomenon in Ghanaian Christianity is likely to cause a rethinking of the conventional notion of PMs as spaces for transcendental encounters. Such a revision may result in the emergence of other themes or concepts of future academic relevance. Keywords: Discourse analysis, sacred, profane, sacred space, prayer rituals, Prayer Mountains
Alternative Methylated Biosignatures. I. Methyl Bromide, a Capstone Biosignature
Authors: Leung Michaela , Schwieterman Edward W. , Parenteau Mary N. , Fauchez Thomas J.
Published: October 2022

The first potential exoplanetary biosignature detections are likely to be ambiguous due to the potential for false positives: abiotic planetary processes that produce observables similar to those anticipated from a global biosphere. Here we propose a class of methylated gases as corroborative “capstone” biosignatures. Capstone biosignatures are metabolic products that may be less immediately detectable, but have substantially lower false-positive potential, and can thus serve as confirmation for a primary biosignature such as O2. CH3Cl has previously been established as a biosignature candidate, and other halomethane gases such as CH3Br and CH3I have similar potential. These gases absorb in the mid-infrared at wavelengths that are likely to be captured while observing primary biosignatures such as O3 or CH4. We quantitatively explore CH3Br as a new capstone biosignature through photochemical and spectral modeling of Earthlike planets orbiting FGKM stellar hosts. We also reexamine the biosignature potential of CH3Cl over the same set of parameters using our updated model. We show that CH3Cl and CH3Br can build up to relatively high levels in M dwarf environments and analyze synthetic spectra of TRAPPIST-1e. Our results suggest that there is a coadditive spectral effect from multiple CH3X gases in an atmosphere, leading to an increased signal-to-noise and greater ability to detect a methylated gas feature. These capstone biosignatures are plausibly detectable in exoplanetary atmospheres, have low false-positive potential, and would provide strong evidence for life in conjunction with other well-established biosignature candidates.

Precision Medicine in Pediatric Cardiology
Authors: Kikano Sandra , Kannankeril Prince J.
Published: October 2022

Precision medicine is a developing strategy for individualized treatment of a wide range of diseases. Congenital heart disease is the most common of all congenital defects and carries a high degree of variability in outcomes because of unidentified causes. Advances have identified individual genetic and environmental factors that have helped understand variations in morbidity and mortality in pediatric cardiology. A focus on genomics and pharmacogenetics has also been key to risk prediction and improvement in drug safety and efficacy in the pediatric population. With the rapidly evolving understanding of these individual factors, there also come challenges in implementation of personalized medicine into our health care model. This review outlines the key features of precision medicine in pediatric cardiology and highlights the clinical effects of these findings in patients with congenital heart disease.

QUANTIFYING THE IMPACT THAT COXSWAIN BEHAVIOUR HAS ON WHOLE BODY VIBRATION - SIMULATOR TRIAL
Authors: Newman T J
Published: October 2022

A common risk to personnel is from Whole Body Vibration (WBV) and shock when transiting at speed in heavy seas, and much research has been done by maritime organisations to reduce this risk and the associated health impacts. It is well
known that coxswain ‘driving style’ can radically affect exposure levels for a given sea state and sustained transit speed. A data-driven approach to define what makes a good coxswain from a WBV perspective is currently being developed by the Naval Design Partnering Team (NDP). In phase 1, a systematic coxswain behaviour tracking methodology has been developed and demonstrated using a motion platform-based fast craft simulator at MARIN. The performance of several experienced volunteer coxswains from MOD, RNLI and KNRM has been evaluated based on a set pattern of tests. The advantages of using the simulator, over a sea trial, have been demonstrated: it is more repeatable, more controllable, accurate and more accessible. The potential disadvantages of the approach are also discussed with reference to feedback
gathered from coxswains. Analysis has shown effective throttle control is much more important than steering to reduce WBV. Several interesting trends in WBV reduction potential have been shown which it is thought, with further validation, could aid mission planning, mission execution and provide data for training autonomous feedback/control algorithms. Further work is required before the findings of this study can be fully exploited. These subsequent phases, which include sea trials, aim to provide validation and further evidence to support the initial findings.
LAB TESTING TO DETERMINE SEATS' CAPACITY TO PROTECT USERS FROM IMPACT-INDUCED INJURIES
Authors: Moxley PR , Lawrence R , Coe TE
Published: October 2022

In recent years, there has been a concerted effort to produce a laboratory standard to test and quantify the performance of shock mitigating seats in high-speed boats. Despite significant progress towards international agreement on the terms of an ISO standard, it was eventually abandoned in favour of varying national-level standards. Some prior publications may lead to misinterpretation, so an overview of the standard is presented to aid the reader in understanding the tenets of the standard, including its objectives and purpose. The remainder of the paper is concerned with rebutting broad categories of
objections. Definition of the test waveform, vulnerability of human occupants, effects of filtering on signals, types and suitability of drop test rigs, and the rejection of “brace” type seats. In each instance, examples are provided of where concerns with the test method are unfounded or based on a misinterpretation of the test method.
HORSES FOR COURSES: HOW TO SELECT THE “RIGHT” WIND PROPULSION SYSTEM AND HOW TO MAKE THE BUSINESS CASE
Authors: Gerhardt F C , Werner S , Hörteborn A , Lundbäck O , Nisbet J , Olsson T
Published: October 2022

Wind propulsion systems (WPS) are major investments and the decision to install them requires careful consideration of many complex questions. In this paper we present a systematic, scientific methodology to assess the benefits and drawbacks of such systems at the early concept stage of a vessel. The purpose is to provide guidance for shipowners and operators and help them make informed decisions. The proposed method was developed into a Software tool called ‘SEAMAN Winds’ and has been correlated to full scale results. The program draws on our large database of model tests, and CFD of hulls and wind propulsion technologies. It uses the intended trading routes of the vessel as an important input, typical output data are:
a) performance values (ship speed, power requirements etc.)
b) environmental parameters (CO2 avoided, EEDI and EEXI reduction, carbon intensity indicator)
c) financial metrics (bunker savings, payback time for installation of WPS)
Potential applications of the method include making the business case for one particular WPS or investigating in how far certain systems are more suited for a specific route than others.
El consumo de agua en la construcción romana con morteros de cal: un método de cálculo
Authors: Martínez Jiménez Javier
Published: October 2022

Los hormigones romanos son una de las áreas de la construcción en la Antigüedad que han atraído más atención. Muchos estudios se han dedicado a las propiedades técnicas y químicas de este hormigón y a la economía de la industria de la construcción romana. En estos estudios, siempre se señala el papel del agua como importante y se indica que se consumía en grandes cantidades. Y aunque se han realizado cálculos para determinar las cantidades de horas de trabajo, de cal, piedra, madera y otros materiales, no ha habido estudios semejantes para calcular los volúmenes de agua necesarios. En este artículo, propongo una serie de ratios -derivadas de las fuentes escritas, recomendaciones modernas y análisis científicos, contrastadas con resultados experimentales- con las cuales llegar a una aproximación a los volúmenes de agua necesarios en las construcciones en mortero romanas. Esto será una útil estimación para futuros estudios sobre las practicidades y las economías de la construcción en mortero en la Antigüedad.

On some dangers of inflation accounting
Authors: Aysan Mustafa A.
Published: October 2022

Die doel van hierdie artikel is nie om 'n indringende omskrywing te gee van metodes wat in Suid-Afrika gebruik word om finansiële state aan te pas by inflasie nie. Die skrywer stel meer basiese vrae, nl. waarheen is die rekenmeestersprofessie op pad met al die verskillende metodes? Hoe kan 'n maatskappy se finansiële state oor tyd ontleed word as verskillende metodes gebruik word? Hoe kan maatskappye in verskillende lande met mekaar vergelyk word op grond van hulle finansiële state? Hy kom tot die slotsom dat die rekenmeesters-professie die sosiale verantwoordelikheid dra om hulle kragte te wy aan pogings om inflasie die hoof te bied en nie om nog meer verwarring te help skep nie.

Published: October 2022

The relationship of retinol binding protein 4 (RBP4) with biomarkers of intestinal health and gut integrity in adults is unknown. We sought to determine the correlation between plasma RBP4 level and BMI and investigate the relationship of circulating RBP4 concentration with biomarkers of environmental enteric dysfunction among lean adults (body mass index [BMI] < 25.0 kg/m2) in Bangladesh. Overall, 270 adults (135 undernourished with a BMI < 18.5 kg/m2 and 135 healthy controls with a BMI between 18.5 and 24.9 kg/m2) aged 18 to 45 years were evaluated. Multivariable linear regression was performed to test the association between RBP4 and fecal biomarkers of impaired gut health. RBP4 concentration was positively correlated (rho = 0.27, P < 0.001) with BMI and was significantly higher in healthy controls than undernourished adults (P < 0.001), in male than female (P < 0.001), and also in employed (P < 0.001), smokers (P = 0.048) and participants with low Self-Reporting Questionnaire (SRQ)—20 scores (an instrument to screen mental health disorders) (P = 0.049). Statistically significant negative correlations were observed between RBP4 and fecal biomarkers of gut enteropathy including myeloperoxidase (rho = –0.23, P < 0.001), neopterin (rho = –0.30, P < 0.001), and alpha-1 anti-trypsin (rho = –0.21, P < 0.001). Multivariable linear regression analysis showed that increased RBP4 concentration was associated with a significant reduction in fecal neopterin (coefficient = –0.95; 95% confidence interval: –1.44 to –0.45]; P < 0.001) after adjustment for age, sex, nutritional status at enrollment, education, dietary diversity score, SRQ-20 score, improved sanitation, household animal exposure, and alpha-1-acid glycoprotein. The study findings revealed an inverse relationship of plasma RBP4 concentration with fecal biomarkers of altered gut health among slum-dwelling lean adults in Bangladesh.

Published: October 2022

Cutaneous leishmaniasis (CL) is endemic in Israel, caused mainly by Leishmania major (L. major) and L. tropica. In addition, returning travelers import another leishmanial species such as L. braziliensis. Although we are dealing with a skin disease, the blood bank in Israel does not accept blood donations from people infected with CL in cases of multiple lesions due to the possibility of transfusion. Our purpose was to investigate the prevalence of Leishmania in the blood of patients with active or previous CL. This pilot study screened patients with active or previous CL for parasites in their blood. All patients were infected in Israel or were returning travelers with leishmaniasis acquired in Latin America. Patients were seen at the Sheba Medical Center. In addition, patients were seen at their homes in L. tropica and L. major endemic regions in Israel. Blood samples were taken from each patient for culture and polymerase chain reaction (PCR). Altogether 62 blood samples were examined (L. tropica = 26, L. major = 33, and L. braziliensis = 3). Twenty-seven patients had an active disease and 35 were recovered. All blood cultures and PCR were negative for parasites except one blood sample that was PCR positive for L. braziliensis. The findings of our study, although a small sample, suggest that people with active or recent CL caused by L. major and L. tropica, do not harbor parasites in their blood. Thus, their exclusion from blood donation should be revisited. Further studies are needed with larger sample size and highly sensitive tests.

Published: October 2022

Only a few studies have explored prognostic factors for tuberculous meningitis (TBM) in children, and an easily applicable bedside prognostic score for TBM has not been developed yet. We compared the sociodemographic, clinical, radiological, and cerebrospinal fluid parameters in the cohort of 94 TBM cases aged 1 to 18 years, with at least 6 months of completed follow-up and determined the prognostic factors associated with poor functional outcome. We assessed our proposed prognostic model using both discrimination and calibration and subsequently used the bootstrap method to validate the model internally. We finally derived an easily applicable bedside prognostic score by rounding off the regression coefficients to the nearest integers. A total of 39 (41%) and 55 (59%) patients had poor and good functional outcomes, respectively, at the end of 6 months (12 died, 13%). In multivariate analysis, a high baseline Pediatric Cerebral Performance Category (PCPC) score, brain infarction in neuroimaging, tonic motor posturing, younger age, and stage III TBM were independent predictors of poor functional outcomes. The final model showed good discrimination (area under the curve = 88.2%, P < 0.001) and good calibration (Hosmer–Lemeshow test, P = 0.53). Bootstrapping also confirmed the internal validity of this model. The PITAS (PCPC score [P], brain infarction in neuroimaging [I], tonic motor posturing [T], age [A], and stage of TBM [S]) score developed from this model has a score ranging from 0 to 12, with a higher score predicting a higher risk of poor functional outcome. The PITAS score performed better than medical research council staging alone in predicting poor functional outcomes (area under the curve = 87.1% versus 82.3%). Our study’s PITAS score, developed and internally validated, has good sensitivity and specificity in predicting poor functional outcomes in pediatric TBM cases at 6 months.

Published: October 2022

Pelvic ring injury is a rare condition with the incidence of hip fracture about 3% to 8% of all fractures. However, the majority of pelvic fracture patients have a high morbidity rate that could threaten their survival. The majority cause of hip fracture is high energy blunt trauma and is related to polytrauma incident.  The main goals of management for pelvic ring injury are to restore the form and stability of the pelvic. The main goal is to prevent nonunion and malunion, which lead to chronic pain and disability. This review is focused on the strengths and weaknesses of the management option, approach and complication for pelvic ring fracture surgery. Complications of pelvic ring fracture surgery are bleeding, nerve damage, DVT, pulmonary embolism, soft tissue injury, sepsis, and malunion of the pelvis and nonunion. Management for pelvic ring fracture surgery is used based on the location and configuration of the fracture, implant availability, surgeon’s preference, and experience.

Multi-Objective Optimal Design of Solar and Wind Hybrid Renewable Energy Systems in Distribution System Considering Daily Uncertainties
Authors: Belbachir Nasreddine , Zellagui Mohamed
Published: October 2022

The problem of energy supply kept floating on the surface. Hybrid Renewable Energy Systems (HRES) are one of the solutions and references to configure the power system and generation. The optimal sizing and placement of HRES in the Electrical Distribution Systems (EDS) is a trendy problem that may be solved using different approaches and algorithms due to their high complexity. The HRES presence in the EDS is so beneficial and advantageous, where in general lead to, power losses reduction, voltage profiles enhancement, growth of the system reliability and loadability, also the improvement of the system’s protection and security. Those benefits are reachable unless the RES is properly optimized in location and size based on different objective functions. In this context, this paper is devoted to utilizing a recent nature-inspired metaheuristic approach called Ant Lion Optimizer (ALO) algorithm to optimally integrate HRES units based on photovoltaic (PV) and wind turbine (WT) sources into the EDS when optimizing and minimizing a multi-objective function (MOF) represented as the total of the techno-economic parameters are the total power losses (TAPL), the total voltage deviation (TVD), the total operating time of overcurrent relays (TOT), and the investments cost of both PV and WT power sources (ICPV) and (ICWT), considering the daily uncertainties of their generation and the load demand. The ALO is validated on the test distribution system of IEEE 33-bus.
Control Strategy of The Permanent Magnet Stepper Motor
Authors: Harrouz Abdelkader , Glaoui Hachemi
Published: October 2022

The stepper motor is an electromechanical converter that transforms a pulsed electrical signal into a mechanical movement (angular or linear). Its basic structure is in the form of two mechanically separated parts, the stator and the rotor. The electromagnetic interaction between these two parts ensures rotation. In the design of automatic systems, one always seeks to improve the dynamic performances and to minimize the response time. Conventional control algorithms, for example, with integral proportional action, may be sufficient if the requirements on the accuracy   and performance of the systems are not too strict.

Authors: Harrouz Abdelkader , COLAK Ilhami , KAYISILI Korhan
Published: October 2022

This paper presents a control strategy of turbine directly driven permanent magnet synchronous generator (PMSG) for a small wind generation system. The mathematical models of a wind turbine system, the PMSG generator and converters have been described. The control algorithms of the converter systems based on the methods of vector control have been applied. The study methodology is based on defining various study cases combining structural and operational parameters of the wind energy systems. The models of the PMSG, the force commutated rectifier, the DC bus, the buck converter and the inverter are developed and used in the control scheme. The objective of this paper is to compare between tow controls with simulation, and with more description of all the system by developing the technique needed to control the converter. The simulation results will show that the proposed control can operate with a good performance in a stand-alone wind energy conversion system for low power generation applications.
contratación temporal por circunstancias de la producción
Authors: Vila Tierno Francisco
Published: October 2022

La última reforma laboral ha supuesto un cambio esencial en la configuración del modelo de contratación laboral en España, apostando, de manera decidida y definitiva, por la contratación estable. La contratación temporal es una excepción, de manera que lo que se hace es intensificar el carácter causal de la misma, así como un reforzamiento de los requisitos formales para atender a tal finalidad. De este modo, se articula como contrato temporal de referencia a aquel que viene motivado por circunstancias de la producción. Un contrato con un doble planteamiento, pero que se sitúa como contrapunto y salvedad al contrato fijo discontinuo, con el que puede tener importantes puntos de fricción. La regulación novedosa de este contrato temporal supone, además, situarnos ante un nuevo espacio de incertidumbre en el que tendrá un papel esencial la jurisprudencia.
SOCIO-ECONOMIC DETERMINANTS OF THE OCCURRENCE AND EXTENSION OF INFORMAL WASTE COLLECTION IN IBADAN NORTH EAST LOCAL GOVERNMENT AREA OF OYO STATE, NIGERIA
Authors:   University of Ilorin, OLA AKEEM , ADEWALE YEMI ,   Federal Polytechnic
Published: October 2022

Against the background of the phenomenal influx of labour into the informal waste management subsector of many cities in Nigeria in recent times, despite the persistent official harassment of the participants and the seemingly low economic reward offered by the job, this paper examines the influence of social and economic attributes of participants on the emergence and development of the sector. Using a cross-sectional survey research design, data were collected via a structured questionnaire interview involving 103 identified informal waste collectors in the Ibadan North East Local Government Area of Oyo State, Nigeria. Both descriptive (frequency and percentage) and inferential statistics (Pearson’s correlation analysis and multinomial logistic regression) were used in analysing the data generated from the questionnaire survey. The study found that informal waste collectors’ socio-economic attributes (gender, age, education, income, marital status, ethnicity, religion, nationalities and state of origin) influenced their participation in waste management. The results of the multinomial logistic regression confirmed the hypothesis that participation in informal waste collection is a function of socio-economic attributes. The study concluded that adequate knowledge of informal waste collectors’ socio-economic attributes will lead to positive policy response from the government towards the subsector, thereby ensuring its sustainability in the waste management sector.

The findings are expected to assist companies in performing well towards achieving sustainable development and maintaining employee satisfaction. This quantitative research uses the questionnaire survey method and collected 216 valid responses from employees working in the food and beverages industry in the Klang Valley in Peninsular Malaysia. The purposive sampling technique was used in this study and the relationship among variables was analysed. The findings show that out of the three proposed antecedents, organisational justice and supervisor support could significantly influence employees’ decision to stay with their current organization. This research could help organisations, specifically those in the Malaysian food and beverages industry, to ensure business sustainability and increase their retention rates by demonstrating that these two factors are critical in POS and turnover intention, as the cost of employee turnover is high. As there has been limited research in the context of this industry in Malaysia, this research provides the organizations with insight and solutions to overcome and reduce employee turnover issues.

Ecotourism is one of the sectors that is expected to contribute towards the Sustainable Development Goals. Ecotourism development should consider disaster risk due to its direct impact on human safety and the environment. This study aims to develop an ecotourism development model based on disaster risk reduction in the Gunung Ciremai National Park (GCNP) and its buffer zone. The model was developed based on the supply and demand analysis. Land suitability analysis was used to estimate ecotourism supply using spatial analysis, combined with multiple-criteria decision analysis. Four parameters with 11 sub-parameters were used in the spatial analysis. Demand was examined by measuring tourist preferences. This study found that only 0.18% of GCNP and its buffer zone are classified as unsuitable for ecotourism development and most of the areas falls under the marginally suitable category. Increasing restoration rate and lowering the allowable development area can expand it carrying capacity from 5.62 million to 5.70 million people per year under the moderate scenario and 5.96 million people per year in the optimistic scenario using a 40-year simulation. Disasters risk can also be reduced by embedding mitigation of and adaptation to disasters in ecotourism management planning.

Community-based tourism (CBT) is a growing niche market that has positively impacted many developing countries including Malaysia. CBT in Malaysia is recognised as the Malaysian Homestay Experience Programme (MHEP) which is under the coordination of the Ministry of Tourism, Arts and Culture. Previous studies have looked into stakeholders’ contributions and the roles they play in the MHEP. However, the sustainability criteria from the multi-stakeholder perspective should be understood. The collaboration between tourism stakeholders is pivotal in understanding their perspective by considering their diverse viewpoints on critical issues and bridging the current knowledge gap. This research aims to investigate how stakeholders could participate more efficiently in developing and employing a sustainable MHEP. This study applied a mixed-method approach and was divided into two phases. The first phase was the multistage qualitative research and the second phase involved a questionnaire survey with structured questions distributed to the multi-stakeholders. Academicians, government agencies, non-governmental organisations, businesses, host communities, homestay coordinators and tourists were involved in the data collection process. The study applied a two-stage methodology by integrating two multi- criteria decision-making techniques, Decision-Making Trial and Evaluation Laboratory and analytic network process to extend the existing evaluation criteria and weightage. The multi-criteria framework will provide stakeholders as decision-makers the ability to devise plans that are sustainable and compatible with conservation and rural development strategies. This study is decisive in helping stakeholders develop sustainable CBT and contribute to government policies, specifically in terms of MHEP development and management aligned with the Malaysia rural development policy. Sustainable CBT can be an efficient rural economic development tool to generate broader economic distribution and create a more comprehensive spatial development. Furthermore, this study also provides valuable insights for tourism policymakers in terms of efficient policy interventions related to CBT in accelerating sustainable development involving environmental, economic and socio-cultural growth.

The Internet of Things (IoT) being a promising technology of the future is expected to generate a tremendous amount of data that may be exposed to security flaws. Hence, to protect IoT applications from hackers, lightweight cryptography has been identified as one of the suitable mechanisms since it is designed to fulfil security demands in resource-constrained hardware and software. This paper aims to analyse the current security requirements in designing lightweight cryptography for IoT applications, specifically for integrity and authentication algorithms. There are three objectives to focus on: Determine the current state of integrity and authentication research, investigate the integrity and authentication requirements, and analyse the lightweight authentication algorithm currently used. The Kitchenham systematic review method was adopted using a four-step process. The selected articles in this study were retrieved from four reputable databases and 57 of them were deemed suitable for analysis after meeting the selection criteria. From this systematic literature review, it was discovered that there were three active research focuses on the IoT. The research focuses were mostly on cyberattacks against IoT applications, system security requirements and algorithms for lightweight authentication. Furthermore, the analysis also revealed the convergence of lightweight authentication algorithms to ensure the future sustainability of applications. This study may provide researchers with a reference in designing lightweight authentication algorithms to achieve the desired security requirements for sustainable security management in IoT.
Small and Micro Food Business Operator (FBO) Tracking Survey: Wave 3 2021 - Technical Report
Authors: Research IFF
Published: October 2022

The Food Standards Agency (FSA) has been tracking small and micro Food Business Operator (FBO) attitudes towards food-related topics, and trust in the FSA and food system, since 2018. This has helped inform engagement and intervention activity targeted at businesses with fewer than 50 staff. The survey was initially developed to assess the perceived impact of changes as a result of the UK’s exit from the European Union (EU), and the Achieving Business Compliance (ABC) programme, which aims to modernise the regulation of food businesses in England, Wales and Northern Ireland. Since then, it has evolved to regularly track small and micro FBO views on a range of subjects. In 2021, the third wave of the annual tracking survey was carried out, with the following aims: To gain insight, and understand the implications of the EU Exit on small and micro enterprises To ‘unpack’ attitudes towards regulation and deepen insights and knowledge of small and micro enterprises, including with regards to the FSA’s ABC priority To measure trust in the FSA and extent to which FSA is considered a modern, accountable regulator All fieldwork for wave 3 was carried out by IFF Research, an independent market research company, commission by FSA. This paper outlines the methodological approach taken for wave 3 of the research, including sampling; feasibility testing; pilot and mainstage fieldwork; response rates; and weighting.
Public participation in decisions on specific activities in Ukraine: state of the art and way forward
Authors: Aleksyeyeva Yelyzaveta
Published: October 2022

The article provides a critical analysis of the state of development of participatory democracy instruments in Ukraine in particular of access to information relevant to the decision-making and public participation in environmental matters. The piece explores the major regulatory shifts in these areas brought by implementation of the EU-Ukraine Association Agreement and associated adoption of legal frameworks on access to public information and on environmental impact assessment. Current legislative proposals on industrial emissions soon to be considered by the Parliament of Ukraine are analysed in detail to demonstrate the continuation of the trend. This leads to a conclusion that access to information and public participation in decisions on specific activities in Ukraine are developing in conformity with the European standards and will continue to develop both in terms of further digitalisation, automatization and customisation for the needs of a specific decision-making, and in terms of covering more environmental permits and other decisions on specific activities.
