Job Shop Scheduling Using Shifting Bottleneck Heuristic Algorithm

Production scheduling is defined as allocating limited resources to do several jobs. PT. Hari Mukti Teknik is a company engaged in manufacturing and engineering in Indonesia. The company implements an FCFS scheduling system with make to order and job shop production system. In order to produce a schedule that is efficient and feasible for the production process in the company, it is necessary to carry out further research on the production scheduling process using the heuristic method. The proposed method is Shifting Bottleneck Heuristic algorithm. This method can determine which machines are experiencing bottlenecks so that the scheduling results in better job sequences and produces a smaller makespan. The current method results in the makespan of 603 hours, while the Shifting Bottleneck Heuristic algorithm has smaller makespan, that is 468.71 hours. The proposed method produces better results than the company's existing method, where EI is 1.287 and RE is -28.651% based on the performance evaluation with EI and RE parameters. Therefore, the Shifting Bottleneck Heuristic algorithm is a better method and can be applied by the company to minimize the makespan.

Foreign aid has been an essential tool for the socio-economic development of developing countries since 1960s. It is described by OECD as the financial, technical assistance and commodity flow to the countries that are in the list of DAC (Development Assistance Committee). US’s Marshall Plan is a well-known development assistance program, which was established between 1948 and 1951 under the European Recovery Program to support Europe in economic crisis after a war became successful in reducing poverty while increasing economic growth. By taking the Marshall plan as a model, developed countries have been supporting the developing countries since then. Recently, the Millennium Development Goals was also launched in New York in 2000 to finance economic growth of poor countries. New actors from other parts of the world took their places in providing development assistance. Despite receiving more than 600 billion USD in the context of foreign aid, large part of Africa has still remained underdeveloped and in an extreme poverty. In this paper, we study the impacts of foreign aid to socio-economic development to Ethiopia. After reviewing the development and foreign aid literature from primary and secondary sources, this study benefited from data gathered from World Bank Database, Transparency International and Freedom House, and then time series data were evaluated by regression analysis. Our findings indicate that foreign aids do not have a major influence on GDP growth; but it has a considerable influence on FDI (foreign direct investment) and unemployment rate in Ethiopia. However, it is observed that foreign aid has negatively correlated with democracy and corruption levels in the country. Although, the amount of foreign aid has been continuously increasing, Ethiopia has remained one of the most corrupt and authoritarian African countries according to related indices. Consequently, our study concludes that foreign aid should be redesigned to encourage and reward receiving countries to advance their democracy and eliminate corruption within the context of recent philosophy and principle of collaborative governance for long term development.

Surgical Treatment of Intramedullary Hemangioblastomas: Current State of Problem (Review)

Intramedullary hemangioblastomas (HAB) refer to very rare highly vascularized vascular spinal cord tumors associated with various neurological disorders. Effective HAB therapy to a greater extent depends on diagnostic accuracy and the absence of intra- and postoperative complications. The present study is a review of publications concerned with modern diagnostic and therapeutic techniques to control spinal HAB. The authors showed that perfusion computed tomography, computed tomographic angiography, and magnetic resonance angiography can be reasonably used for diagnosis and differentiation in a number of HAB due to their high vascularization. Preoperative embolization significantly reducing intraoperative bleeding risks is highly efficient. Some authors recommend this procedure in case of large lesions and high risks of intraoperative bleeding. The review also considered intraoperative imaging of a tumor and its feeding vessels using indocyanine green providing inspectability over the total tumor resection and clear imaging of tumor vascular architecture. The advantages and restrictions of the mentioned procedures were described.
Studying Aptamer Binding to Cancer Cell Membrane Receptors by Fluorescence Correlation Spectroscopy

Aptamers are short strands of oligonucleotides, designed to have excellent binding affinity and selectivity towards certain target molecules. Due to their capacity to bind tightly and specifically to their ligands, aptamers have applications in fields ranging from medicine to biochemical research. Fluorescence correlation spectroscopy (FCS) is being recognized as a highly sensitive method for the investigation of molecular interactions. By using this technique, association and dissociation rate constants, and binding constants can be obtained from the analysis of the Brownian motion of fluorescently labeled probes. The present study is focused on cancer cell-specific aptamers binding to their target. For determination of the dissociation rate constant, a binding curve is obtained by incubating the target cells with different concentrations of fluorescently-labeled aptamer. The binding constants are then compared to the ones that have been reported by flow cytometry. Further, a method for calculation of the aptamer receptor density on the cell membrane is proposed. The study will show that FCS is a reliable method for the determination of binding properties of aptamer-target complexes even when used in vivo. ( en )
Defibration of Bacterial Cellulose Gel by Grafting Poly (ε-Caprolactone) and Preparation of its Suspension for Easy Manufacturing

Introduction Cellulose nanofibers (CNF) have drawn much attention in recent years as a bioplastic. The CNF extracted from plant cells are composed of several molecular chains [1] and are expected to be used for film [2], filler [3], and in parts of industrial products such as automobiles. Additionally, cellulose nanocrystal (CNC) obtained by further treatment with CNF are also one of the promising nanomaterials [4]. To expand the applications using CNFs or CNCs, polymer grafting has been proposed and ring
A RESTful Northbound Interface for Applications in Software Defined Networks

: Software Defined Networking (SDN) aims to help overcome the complexities inherent in traditional networks. The main concept in SDN is the decoupling of the data layer from the control layer, the latter of which is centralised in a controller. OpenFlow has been adopted as the standard protocol for the southbound interface, where the controller communicates with forwarding devices. However, the northbound interface (NBI), connecting the controller with end-user business applications, does not have an open standard. NBIs have accelerated application development because developers can implement required functionality without the need to consider matters related to the data layer, but there is an issue of compatibility because each SDN has its own NBI. In this position paper we present a plan to design a RESTful NBI for SDN applications to improve compatibility across SDN technologies.
How Reflective Automated e-Coaching Can Help Employees Improve Their Capacity for Resilience: Mixed Methods Study

Background An eHealth tool that coaches employees through the process of reflection has the potential to support employees with moderate levels of stress to increase their capacity for resilience. Most eHealth tools that include self-tracking summarize the collected data for the users. However, users need to gain a deeper understanding of the data and decide upon the next step to take through self-reflection. Objective In this study, we aimed to examine the perceived effectiveness of the guidance offered by an automated e-Coach during employees’ self-reflection process in gaining insights into their situation and on their perceived stress and resilience capacities and the usefulness of the design elements of the e-Coach during this process. Methods Of the 28 participants, 14 (50%) completed the 6-week BringBalance program that allowed participants to perform reflection via four phases: identification, strategy generation, experimentation, and evaluation. Data collection consisted of log data, ecological momentary assessment (EMA) questionnaires for reflection provided by the e-Coach, in-depth interviews, and a pre- and posttest survey (including the Brief Resilience Scale and the Perceived Stress Scale). The posttest survey also asked about the utility of the elements of the e-Coach for reflection. A mixed methods approach was followed. Results Pre- and posttest scores on perceived stress and resilience were not much different among completers (no statistical test performed). The automated e-Coach did enable users to gain an understanding of factors that influenced their stress levels and capacity for resilience (identification phase) and to learn the principles of useful strategies to improve their capacity for resilience (strategy generation phase). Design elements of the e-Coach reduced the reflection process into smaller steps to re-evaluate situations and helped them to observe a trend (identification phase). However, users experienced difficulties integrating the chosen strategies into their daily life (experimentation phase). Moreover, the identified events related to stress and resilience were too specific through the guidance offered by the e-Coach (identification phase), and the events did not recur, which consequently left users unable to sufficiently practice (strategy generation phase), experiment (experimentation phase), and evaluate (evaluation phase) the techniques during meaningful events. Conclusions Participants were able to perform self-reflection under the guidance of the automated e-Coach, which often led toward gaining new insights. To improve the reflection process, more guidance should be offered by the e-Coach that would aid employees to identify events that recur in daily life. Future research could study the effects of the suggested improvements on the quality of reflection via an automated e-Coach.
Climate-driven variation in biotic interactions provides a narrow and variable window of opportunity for an insect herbivore at its ecological margin

Climate-driven geographic range shifts have been associated with transitions between dietary specialism and generalism at range margins. The mechanisms underpinning these often transient niche breadth modifications are poorly known, but utilisation of novel resources likely depends on phenological synchrony between the consumer and resource. We use a climate-driven range and host shift by the butterfly Aricia agestis to test how climate-driven changes in host phenology and condition affect phenological synchrony, and consider implications for host use. Our data suggest that the perennial plant which was the primary host before range expansion is a more reliable resource than the annual Geraniaceae upon which the butterfly has become specialised in newly colonised parts of its range. In particular, climate-driven phenological variation in the novel host Geranium dissectum generates a narrow and variable ‘window of opportunity’ for larval productivity in summer. Therefore, although climatic change may allow species to shift hosts and colonise novel environments, specialisation on phenologically-limited hosts may not persist at ecological margins as climate change continues. We highlight the potential role for phenological (a)synchrony in determining lability of consumer-resource associations at range margins, and the importance of considering causes of synchrony and success in biotic interactions when predicting range shifts.
FAIR geovisualizations: definitions, challenges, and the road ahead

ABSTRACT The availability of open data and of tools to create visualizations on top of these open datasets have led to an ever-growing amount of geovisualizations on the Web. There is thus an increasing need for techniques to make geovisualizations FAIR – Findable, Accessible, Interoperable, and Reusable. This article explores what it would mean for a geovisualization to be FAIR, presents relevant approaches to FAIR geovisualizations and lists open research questions on the road towards FAIR geovisualizations. The discussion is done using three complementary perspectives: the computer, which stores geovisualizations digitally; the analyst, who uses them for sensemaking; and the developer, who creates them. The framework for FAIR geovisualizations proposed, and the open questions identified are relevant to researchers working on findable, accessible, interoperable, and reusable online visualizations of geographic information.
Short Communication Cyanidin does not affect sulforaphane-mediated Nrf2 induction in cultured human keratinocytes

There is increasing interest in the gene-regulatory activities of isothiocyanates and flavonoids in human skin. Nrf2 agonists, such as isothiocyanate sulforaphane (SFN), have been shown to promote chemopreventive effects in skin both in vitro and in vivo. Recent data indicate that different secondary plant compounds may either antagonise or enhance SFN-induced Nrf2 activation. We therefore studied the interactions of a flavonoid, cyanidin and the potent Nrf2 inductor SFN in cultured human keratinocytes (HaCaT cells). We observed that cyanidin does not induce the activation of Nrf2 and its target genes, g-glutamylcysteine synthetase (gGCS), NAD(P)H: quinone oxidoreductase 1 and haem oxygenase-1 in HaCaT cells. Furthermore, SFN-mediated Nrf2 activation and its target gene expression were not further enhanced by the co-application of SFN with cyanidin.
Effects of Parental Involvement in a Preschool-Based Eye Health Intervention Regarding Children’s Screen Use in China

In this digital era, young children spend a considerable amount of time looking at telephone, tablet, computer and television screens. However, preventative eye health behavior education could help avoid and relieve asthenopia. The effects of parental influence on their children’s eye health behavior through the preschool eye health education intervention program were examined. The Health Belief Model was used to develop parental involvement strategy and eye health curriculum. The study was conducted in a large public preschool with five branches in Beijing, China. A total of 248 parent–child pairs participated in the baseline and follow-up surveys, of which 129 were in the intervention group and 119 were in the comparison group. The generalized estimating equation analysis results indicated that parental involvement in preschool-based eye health intervention on screen uses had positive influence on parents’ eye health knowledge, cues to action, and parenting efficacy. The intervention program also had positive effects on the increasing level of children’s eye health knowledge, beliefs, cues to action, self-efficacy, and behaviors. The results supported the implementation of a preschool-based eye health intervention program with parental involvement, which could potentially enhance children’s and parents’ eye health beliefs and practices.
The Implementation of Group Investigation Learning Model Through Domino Mathematics Media on the Rank Number and Root Form Materials

This study aims to find out the results of students' learning through the implementation of a group investigation learning model through mathematical domino media better than the implementation of a conventional learning model on the rank number and root form materials. The research was a quasi-experiment with the design of a randomized control group pretest-posttest. The population of this research is the entire class IX SMP Negeri 1 Lhokseumawe consisting of 9 classes. The research sample was determined by a randomized technique that made 2 classes namely experiment class (IXA) and control class (IXB). The results of the student posttest data test show that the data is distributed normally and homogeneously, so it can be analyzed with one-side t-test statistics at a significant α= 0.05. Based on the results of data processing against the posttest students obtained sig scores. (2-tailed) posttest data is 0.001 which means less than α= 0.05, this means H0 is rejected, so it can be concluded that the learning results of students taught by the group investigation learning model through domino mathematics media are better than conventional learning models on the rank number and root form materials in grade IX of SMP Negeri 1 Lhokseumawe.
PAS: A new powerful and simple quantum computing simulator

In recent years, many researchers have been using CPU for quantum computing simulation. However, in reality, the simulation efficiency of the large‐scale simulator is low on a single node. Therefore, striving to improve the simulator efficiency on a single node has become a serious challenge that many researchers need to solve. After many experiments, we found that much computational redundancy and frequent memory access are important factors that hinder the efficient operation of the CPU. This paper proposes a new powerful and simple quantum computing simulator: PAS (power and simple). Compared with existing simulators, PAS introduces four novel optimization methods: efficient hybrid vectorization, fast bitwise operation, memory access filtering, and quantum tracking. In the experiment, we tested the QFT (quantum Fourier transform) and RQC (random quantum circuits) of 21 to 30 qubits and selected the state‐of‐the‐art simulator QuEST (quantum exact simulation toolkit) as the benchmark. After experiments, we have concluded that PAS compared with QuEST can achieve a mean speedup of 8.69× (QFT), 2.62× (RQC) (up to 10.76× , 4.87× ) on the Intel Xeon E5‐2670 v3 CPU.
A novel approach in heart-rate-variability analysis

Heart-rate variability (HRV), measured by the fluctuation of beat-to-beat intervals, has been growingly considered the most important hallmark of heart rate (HR) time series. HRV can be characterized by various statistical measures both in the time and frequency domains, or by nonlinear methods. During the past decades, an overwhelming amount of HRV data has been piled up in the research community, but the individual results are difficult to reconcile due to the different measuring conditions and the usually HR-dependent statistical HRV-parameters applied. Moreover, the precise HR-dependence of HRV parameters is not known. Using data gathered by a wearable sensor of combined heart-rate and actigraphy modalities, here, we introduce a novel descriptor of HRV, based on a modified Poincaré plot of 24-h RR-recordings. We show that there exists a – regressive biexponential – HRV versus HR “master” curve (“M-curve”) that is highly conserved for a healthy individual on short and medium terms (on the hours to months scale, respectively). At the same time, we reveal how this curve is related to age in the case of healthy people, and establish alterations of the M-curves of heart-attack patients. A stochastic neuron model accounting for the observed phenomena is also elaborated, in order to facilitate physiological interpretation of HRV data. Our novel evaluation procedure applied on the time series of interbeat intervals allows the description of the HRV(HR) function with unprecedented precision. To utilize the full strength of the method, we suggest a 24-hour-long registration period under natural, daily-routine circumstances (i.e., no special measuring conditions are required). By establishing a patient’s M-curve, it is possible to monitor the development of his/her status over an extended period of time. On these grounds, the new method is suggested to be used as a competent tool in future HRV analyses for both clinical and training applications, as well as for everyday health promotion.
Control of Airborne Microorganisms by Essential Oils Released by VaxiPod

Currently, due to the global pandemic caused by severe acute respiratory syndrome coronavirus SARS-CoV-2, new procedures and devices for effective disinfection of indoor air are of obvious interest. Various studies demonstrated quite broad ranges of the efficiency of essential oils in the control of biological aerosols. This project reports the results of investigation of the antimicrobial activity of essential oils natural for Australia (tea tree oil, eucalyptus oil and lemon myrtle) distributed by newly developed VaxiPod device for various scenarios, including bacterial, viral and fungal inactivation on various surfaces and in aerosol form. It was found that the device was capable of operating continuously over 24-h periods, providing sufficient aerosol concentration to efficiently inactivate microorganisms both on the surface and in airborne form. Twenty-four to forty-eight hours were required to achieve inactivation above 90% of most of the tested microbes on solid surfaces (stainless steel discs and agar plates), whilst similar efficiency of inactivation on fibrous filter surface as well as in aerosol form was achieved over 30–60 min of the process run. The results look very promising for further development of bioaerosol inactivating procedures and technologies for air quality control applications.
