BackgroundIndividual differences have been detected in individuals with opioid use disorders (OUD) in rehabilitation following protracted abstinence. Recent studies suggested that prediction models were effective for individual-level prognosis based on neuroimage data in substance use disorders (SUD).AimsThis prospective cohort study aimed to assess neuroimaging biomarkers for individual response to protracted abstinence in opioid users using connectome-based predictive modelling (CPM).MethodsOne hundred and eight inpatients with OUD underwent structural and functional magnetic resonance imaging (fMRI) scans at baseline. The Heroin Craving Questionnaire (HCQ) was used to assess craving levels at baseline and at the 8-month follow-up of abstinence. CPM with leave-one-out cross-validation was used to identify baseline networks that could predict follow-up HCQ scores and changes in HCQ (HCQfollow-up−HCQbaseline). Then, the predictive ability of identified networks was tested in a separate, heterogeneous sample of methamphetamine individuals who underwent MRI scanning before abstinence for SUD.ResultsCPM could predict craving changes induced by long-term abstinence, as shown by a significant correlation between predicted and actual HCQfollow-up(r=0.417, p<0.001) and changes in HCQ (negative: r=0.334, p=0.002；positive: r=0.233, p=0.038). Identified craving-related prediction networks included the somato-motor network (SMN), salience network (SALN), default mode network (DMN), medial frontal network, visual network and auditory network. In addition, decreased connectivity of frontal-parietal network (FPN)-SMN, FPN-DMN and FPN-SALN and increased connectivity of subcortical network (SCN)-DMN, SCN-SALN and SCN-SMN were positively correlated with craving levels.ConclusionsThese findings highlight the potential applications of CPM to predict the craving level of individuals after protracted abstinence, as well as the generalisation ability; the identified brain networks might be the focus of innovative therapies in the future.

Full textAbstract:
Project scheduling is an important task in project management which monitors the project duration, resource utilization and affects the benefit of project for all kinds of project such as construction, IT, renewable energy, product design and manufacturing etc. Among many methods for project management, critical path method (CPM) is one of the better-known planning and control techniques in project scheduling. In this study, CPM-based computerized program was developed together with modeling of step by step calculations of parameters of interest such as earliest starts and finishes, slack and float times of project activities resulting in determination of critical path for the project. One advantage of computer implementation of CPM using MATLAB in this study is that unlike conventional method, it eliminates necessity to conventionally draw network diagram to perform critical path analysis.

Purpose We investigated the efficacy of contralateral prophylactic mastectomy (CPM) in reducing contralateral breast cancer incidence and breast cancer mortality among women who have already been diagnosed with breast cancer. Methods This retrospective cohort study comprised approximately 50,000 women who were diagnosed with unilateral breast cancer during 1979 to 1999. Using computerized data confirmed by chart review, we identified 1,072 women (1.9%) who had CPM. We obtained covariate information for these women and for a sample of 317 women who did not undergo CPM. Results The median time from initial breast cancer diagnosis to the end of follow-up was 5.7 years. Contralateral breast cancer developed in 0.5% of women with CPM, metastatic disease developed in 10.5%, and subsequent breast cancer developed in 12.4%; 8.1% died from breast cancer. Contralateral breast cancer developed in 2.7% of women without CPM, and 11.7% died of breast cancer. After adjustment for initial breast cancer characteristics, treatment, and breast cancer risk factors, the hazard ratio (HR) for the occurrence of contralateral breast cancer after CPM was 0.03 (95% CI, 0.006 to 0.13). After adjustment for breast cancer characteristics and treatment, the HRs for the relationship of CPM with death from breast cancer, with death from other causes, and with all-cause mortality were 0.57 (95% CI, 0.45 to 0.72), 0.78 (95% CI, 0.57 to 1.06), and 0.60 (95% CI, 0.50 to 0.72), respectively. Conclusion CPM seems to protect against the development of contralateral breast cancer, and although women who underwent CPM had relatively low all-cause mortality, CPM also was associated with decreased breast cancer mortality.

Network analysis is part of a project that requires time for each network activity. To produce a particular project there is more than one job/event that must be done. Each job/event is interconnected and placed in order according to the management of its implementation. In network projects, it is necessary to plan and supervise systematically, in order to obtain work efficiency. The network is represented in symbols and arrows. In this study, the problem-solving network analysis was solved using the CPM (Critical Path Method) method and with a linear programming model using the help of excel-solver and Lingo. This study aims to compare the two methods in solving network analysis problems. Based on the analysis, it is found that by using the CPM method, more critical paths are obtained than the linear programming method. With the increasing number of critical paths obtained, it is hoped that the management can determine project priorities to maintain the project schedule to be completed on time.

Alcohol misuse is associated with altered punishment and reward processing. Here, we investigated neural network responses to reward and punishment and the molecular profiles of the connectivity features predicting alcohol use severity in young adults. We curated the Human Connectome Project data and employed connectome-based predictive modeling (CPM) to examine how functional connectivity (FC) features during wins and losses are associated with alcohol use severity, quantified by Semi-Structured Assessment for the Genetics of Alcoholism, in 981 young adults. We combined the CPM findings and the JuSpace toolbox to characterize the molecular profiles of the network connectivity features of alcohol use severity. The connectomics predicting alcohol use severity appeared specific, comprising less than 0.12% of all features, including medial frontal, motor/sensory, and cerebellum/brainstem networks during punishment processing and medial frontal, fronto-parietal, and motor/sensory networks during reward processing. Spatial correlation analyses showed that these networks were associated predominantly with serotonergic and GABAa signaling. To conclude, a distinct pattern of network connectivity predicted alcohol use severity in young adult drinkers. These “neural fingerprints” elucidate how alcohol misuse impacts the brain and provide evidence of new targets for future intervention.

Abstract Much recent attention has been directed toward elucidating the structure of social interaction–communication dimensions and whether and how these symptom dimensions coalesce with each other in individuals with autism spectrum disorder (ASD). However, the underlying neurobiological basis of these symptom dimensions is unknown, especially the association of social interaction and communication dimensions with brain networks. Here, we proposed a method of whole-brain network-based regression to identify the functional networks linked to these symptom dimensions in a large sample of children with ASD. Connectome-based predictive modeling (CPM) was established to explore neurobiological evidence that supports the merging of communication and social interaction deficits into one symptom dimension (social/communication deficits). Results showed that the default mode network plays a core role in communication and social interaction dimensions. A primary sensory perceptual network mainly contributed to communication deficits, and high-level cognitive networks mainly contributed to social interaction deficits. CPM revealed that the functional networks associated with these symptom dimensions can predict the merged dimension of social/communication deficits. These findings delineate a link between brain functional networks and symptom dimensions for social interaction and communication and further provide neurobiological evidence supporting the merging of communication and social interaction deficits into one symptom dimension.

Abstract There are many sub-tasks and tools in general overhaul activities, so that a planned and systematic arrangement are needed. In systematic general overhaul planning can use the Network Planning method. Scheduling by the Network Planning method describes a task into a network. The Network Planning has two commonly used techniques, namely CPM (Critical Method Path) and PERT (Program Evaluation and Review Technique). Therefore, in this study, scheduling will be carried out by the Network Planning method, CPM and PERT techniques. By using network planning in overhaul activities, it is hoped that it will be able to identify deviations and critical paths in the sequence of work processes so as to prevent delays in completing work.

Full textAbstract:
The Critical Path Method (CPM) is useful for planning and control of complex projects. The CPM identifies the critical activities in the critical path of an activity network. The successful implementation of CPM requires the availability of clear determined time duration for each activity. However, in practical situations this requirement is usually hard to fulfil since many of activities will be executed for the first time. Hence, there is always uncertainty about the time durations of activities in the network planning. This has led to the development of fuzzy CPM. In this paper, a new approach of ranking fuzzy numbers using centroid of centroids of fuzzy numbers to its distance from original point is proposed. The proposed method can rank all types of fuzzy numbers including crisp numbers with different membership functions. The authors apply the proposed ranking method to develop a new fuzzy CPM. The proposed method is illustrated with an example.

<strong>Abstract:</strong> Least cost scheduling of construction projects is obtained by time management with optimum cost which is also termed as crashing. Although papers published in major journals have documented real applications for schedule crashing such as working overtime, working double shifts, adding additional resources, employee productivity, and relaxing activities. The objectives of the paper are to study the algorithms from the previous studies and their impact on the real-life project crashing. And in addition to that the paper discussed the main idea of crashing PERT/CPM network. To achieve such objectives, studies about crashing algorithm/programing, data collection, and PERT/CPM network crashing technique were carefully explored and scrutinized. Suggestions for further research are for preventive actions for nonconformance risk activities may suffer additional cost, and to use this data to create new procedures that incorporate quality concepts into project scheduling difficulties. <strong>Keywords:</strong><em> </em>Least Cost Scheduling, Crashing using algorithms, PERT/CPM network. <strong>Title:</strong> INTRODUCTION OF LEAST COST SCHEDULE AND ITS APPLICATIONS <strong>Author:</strong> Nasser Majrashi, Ahmed Althobaiti <strong>International Journal of Mechanical and Industrial Technology </strong> <strong>ISSN 2348-7593 (Online)</strong> <strong>Vol. 12, Issue 2, October 2024 - March 2025</strong> <strong>Page No: 54-59</strong> <strong>Research Publish Journals</strong> <strong>Website: www.researchpublish.com</strong> <strong>Published Date: 26-December-2024</strong> <strong>DOI: </strong><strong>https://doi.org/10.5281/zenodo.14558255</strong> <strong>Paper Download Link (Source)</strong> <strong>https://www.researchpublish.com/papers/introduction-of-least-cost-schedule-and-its-applications</strong>

In recent years, CPM - Continuous Passive Motion has been proved to be one of the most effective therapeutic methods for patients who have problems with motion such as spinal cord injury, ankle and knee injury, parkinson and so on. Many commercial CPM devices are found in market but all of them use motors as the main actuators. The lack of human compliance of electric actuators, which are commonly used in these machines, makes them potentially harmful to patients. An interesting alternative, to electric actuators for medical purposes, particularly promising for rehabilitation, is a pneumatic artificial muscle (PAM) actuator because of its high power/weight ratio and compliance properties. However, the highly nonlinear and hysteresis of PAM make it the challenging for design and control. In this study, a PID compensation using neural network control is studied to improve the control performance of the novel model of Knee CPM device.

Abstract Maternal bonding early postpartum lays an important foundation for child development. Changing brain structure and function during pregnancy and postpartum may underscore maternal bonding. We employed connectome-based predictive modeling (CPM) to measure brain functional connectivity and predict self-reported maternal bonding in mothers at 2 and 8 months postpartum. At 2 months, CPM predicted maternal anxiety in the bonding relationship: Greater integration between cerebellar and motor–sensory–auditory networks and between frontoparietal and motor–sensory–auditory networks were associated with more maternal anxiety toward their infant. Furthermore, greater segregation between the cerebellar and frontoparietal, and within the motor-sensory-auditory networks, was associated with more maternal anxiety regarding their infant. We did not observe CPM prediction of maternal bonding impairments or rejection/anger toward the infant. Finally, considering 2 and 8 months of data, changes in network connectivity were associated with changes in maternal anxiety in the bonding relationship. Our results suggest that changing connectivity among maternal brain networks may provide insight into the mother–infant bond, specifically in the context of anxiety and the representation of the infant in the mother’s mind. These findings provide an opportunity to mechanistically investigate approaches to enhance the connectivity of these networks to optimize the representational and behavioral quality of the caregiving relationship.

This research aims to analyze the scheduling of the fiber optic network construction project in Lemo-Lemo, Bulukumba, using the Critical Path Method (CPM). This method was chosen to improve time and cost efficiency in project implementation. Research data were obtained through field observations, literature studies, and interviews with related parties. Analysis was carried out by mapping project activities, estimating duration, and calculating resource requirements and project costs. The results showed that the application of the CPM method was able to accelerate project completion from the initial estimate of 40 days to 21 days, with time savings of 19 days. In addition, the project cost which was initially estimated at Rp. 38,386,680 was successfully reduced to Rp. 37,000,000, resulting in a savings of Rp. 1,386,680. In conclusion, the CPM method proved to be effective in improving time and cost efficiency in fiber optic network construction projects. Therefore, it is recommended that this method be applied consistently in similar projects in the future.

The problem The with development projects is to determine the project schedule so that it can be completed in an optimal (minimum) time. Scheduling with Network, among others, uses the CPM (Critical Path Method). The network diagram representation of the method is in the form of a directed graph (digraph) which is presented in two models, namely AOA (Activity On Arc) and AON (Activity On Node. Activities in the AON model are placed on nodes. This study aims to determine the application of network analysis using the CPM method. The AON model on the scheduling of the library development project at UIN Malang The methods used are forward pass, backward pass, and total slack so that it can be known the fastest or late time an activity can be started or ended and the amount the allowable delay time for an activity and its critical activities.Previous research only used the PERT (Program Evaluation and Review Technique) method and the Gantt Chart method, so in this study the author will use another method, namely the CPM Model AON method. pen time the construction project schedule is 293 days starting from 01-07-2022 to 27-05-2023. From the results of the analysis using the CPM method, it was obtained that from 298 project preparation activities, 17 activities were critical activities so that their implementation could not be delayed because it would result in a delay in project completion time.

A construction project is a form of activity that lasts for a limited period of time, with certain resources, where the process requires a technique to be used, namely management, planning, scheduling to control. It is not uncommon for construction projects to experience delays in completing the completion time, so that many losses occur, especially in time and costs. With this fierce competition, timely completion of projects is a top priority for construction companies. The purpose of this study is to evaluate the time of scheduling for project completion using the CPM method on the grounds that the shape of the network or network planning can be identified along with the activities that are on the critical path, and can also be known for a more efficient time in carrying out this project. Based on network planning analysis using the CPM method, a series of work activities were obtained that were included in the critical path and the evaluation results showed that the project could be completed in 668 days and then accelerated using the CPM method again, so the project could be accelerated to 545 days, so that the percentage of time efficiency after crashing is 18.42%, with a total cost of IDR 176,557,549,469.00 with a percentage of cost efficiency after crashing is 0.03%.

Purpose Over the 30 years, public management and administration scholars have crossed disciplinary boundaries to build a body of scholarship on collaboration for public good, services, and values. The paper aims to discuss these issues. Design/methodology/approach Public management and administration researchers need to integrate the scholarship on collaboration through systems thinking. How do we define collaboration? How do we distinguish among the categories of collaborative public management (CPM), collaborative governance (CG), and networks? How do systems and institutional context shape collaboration in these categories? Within these categories, what are our units of analysis: individual leadership, organizations, or groups in collaboration processes? How do we apply what we know to practice and design? Findings The work requires that the authors examine CPM, CG, and networks in their larger and nested institutional contexts to determine how they are related to and shape each other. The Institutional Analysis and Development framework may inform this work. CPM or networks may be nested in CG processes and structures in inter-governmental contexts. Research limitations/implications Researchers need more clarity as to the context within which CPM, CG, and networks occur, and in units of analysis and the roles of individual people as managers and as agents of organizations, as distinguished from organizations as constructs. Practical implications Scholars need to apply research to practice related to designing systems and structures in which collaboration occurs. Social implications As humankind faces increasingly complex and multifaceted policy problems that cross inter-governmental and international boundaries and require inter-sectoral work, managers and organizations must improve both the design of collaboration in governance and management and mastery of essential skills to participate in collaboration. Originality/value CPM, CG, and network research does not sufficiently incorporate or control for institutional context into research design.

Full textAbstract:
The 6 cpm omnipresent slow waves recorded in the circular muscle (CM) layer of canine colon are generated at the submucosal surface of the CM layer. After removal of the submucosal network of interstitial cells of Cajal (ICC), 66% of the CM preparations (25 of 38) were quiescent in Krebs solution. In the presence of carbachol, seven of nine of these spontaneously quiescent CM preparations demonstrated slow wave-like activity with mean frequency, duration and amplitude of 5.9 ± 0.4 cpm, 2.8 ± 0.5 s, and 0.8 ± 0.2 mV, respectively. Similar slow wave-like activities were induced by TEA (seven out of eight quiescent CM preparations) with frequency, duration and amplitude of 6.1 ± 0.2 cpm, 2.7 ± 0.5 s, and 1.0 ± 0.2 mV, respectively, and by BaCl2 (eight of eight quiescent CM preparations) with frequency, duration, and amplitude of 6.3 ± 0.3 cpm, 1.8 ± 0.2 s, and 0.5 ± 0.1 mV, respectively. All the induced activities were abolished in the presence of 1 μM D600. CM preparations with the submucosal ICC network intact (ICC–CM) showed slow wave activity in Krebs solution at a frequency of 6.2 ± 0.2 cpm, a duration of 3.6 ± 0.2 s, and an amplitude of 1.0 ± 0.1 mV (n = 22). When ICC–CM preparations were stimulated by BaCl2, carbachol, or TEA, the slow wave frequency did not change significantly, but the duration increased as well as the amplitude. In the presence of D600, the upstroke of slow waves remained and the frequency was not affected. The ability to generate slow wave-like activity after potassium conductance blockade in spontaneously quiescent CM disconnected from the ICC network suggested that circular muscle cells have ionic mechanisms for intrinsic oscillatory activity and are capable of actively participating in the conduction and generation of slow waves.Key words: colon, smooth muscle, interstitial cells of Cajal, canine, slow waves, excitability.

The efficiency of project implementation time becomes one of the efforts in optimizing the use of implementation time. CPM is one of the network methods used to determine the critical path of each implementation. This research aims to optimize Time by applying CPM methods in the Kadiri University Clinic construction project in Kediri. The project consists of 2 floors with 12 essential items of work. The implementation time of the project is planned to be complete for 134 days. The data used in this study form a project schedule (Gantt chart). From the data, analysis of the sequence of implementation using the Work Breakdown Structure (WBS) method and carried out the calculation of earliest start (ES), latest start (LS), earliest finish (EF), and latest finish (LF). Critical paths are known from slack/float calculations and are depicted in the form of network diagrams. From the analyses, it is known that the project can be complete within 71 days. The results were 63 days earlier than planned. With the use of the CPM method in project scheduling, optimal timing and critical implementation are found. So that it can be used as a reference in the performance of the project implementation.

In this paper, we present the design and control of continuous passive motion (CPM) machine based on Constraint-Induced Movement Therapy (CIMT) for a patient who needs knee rehabilitation. First, the dynamic model of the CPM machine is derived by the principal of virtual work in dynamics. Then, an intelligent sliding-mode control (ISMC) system which involved recurrent Chebyshev neural network (RCNN) estimator to estimate the unknown external disturbance and uncertainty online is proposed to track the angular position and velocity of the CPM machine. Furthermore, we prove that the proposed ISMC system is asymptotically stable via Lyapunov theory. Finally, the experimental results are illustrated to demonstrate that the ISMC system can effectively reduce chattering phenomenon and precisely track reference trajectory of the CPM machine.

Full textAbstract:
Contemporary Project Management has conceived tools based on mathematical models for planning, scheduling and controlling the projects, the costs and resources. Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT) are two network-based methods which were independently developed to assist the project managers in order to schedule complex real-life projects. A scheduling of a small-scale R&D project using these optimization time-oriented methods was accomplished. In many models of project network some activities are closely related to each other such as procurement activities of basic resources and research activities. If this precedence relationship is on the critical path, that means without no event slack or float time for activities, then some procurements delay may cause lag in the project’s completion time. Thus a good estimation for procurement and research activities duration is needed for a Just-in-Time project.

Full textAbstract:
The post-contract phase of the construction process remains critical to cost management. Several techniques have been used to facilitate effective cost management in this phase. However, the deployment of these techniques has not caused a reduction in the incidence of cost overruns hence casting doubts on their utility. The seeming underwhelming performance posted by these post-contract cost control techniques (PCCTs), has been traced to improper deployment by construction project managers (CPM) and quantity surveyors (QS). Utilizing the perspectives of CPM and QS professionals, as elicited through a survey, produced 135 samples. The instrumentality of the artificial neural networks (ANN) in this study enabled the development of a structured decision-support methodology for analysing the most appropriate PCCTs to be deployed to different construction process phases. Besides showcasing the utility of the emergent ANN-based decision support methodology, the study’s theoretical findings indicate that CPM and QS professionals influence decisions pertaining to PCCTs choice in distinct phases of the construction process. Whereas QS professionals were particularly responsible for the choice of PCCTs during the initial and mid-level phases, CPM professionals assumed responsibility for PCCTs selection during the construction process close-out phase. In construction cost management practice, the crucial PCCTs identifies more with the application of historical data and all cost monitoring approaches.

A housing and settlement building project (residential construction), is a housing or settlement development project based on development stages that are simultaneous with the provision of supporting infrastructure. Construction projects have obstacles, including delays in work implementation times and cost overruns. The aim of this research is to analyze the optimal and efficient time duration for housing construction projects using the CPM (Critical Path Method) method. This research uses the Critical Path Method (CPM). The data in this research comes from the work schedule (time schedule) and budget plan made by the management of the Griya Sejahtera Colomadu 2 Housing Development. The data collected was analyzed using the CPM method and then searched for critical work paths/trajectories using a work network. (network planning), after obtaining the maximum time limit, the next job will be accelerated using the Critical Path Method (CPM). Then, for the cost optimization analysis in this research, the acceleration method was used with the alternative of additional labor. Based on the research results, it was found that the Griya Sejahtera Colomadu 2 Housing Development project experienced delays in work implementation times and cost overruns, namely with a total duration of 242 working days, and the normal duration of critical work was 190 working days. The results of the acceleration calculation with the alternative of additional labor have a total duration of 152 days and have a total labor wage cost of IDR 46,993,580.88.

Full textAbstract:
Background: To investigate the regulatory patterns of Chinese patent medicine (CPM) interventions on lipid metabolism disorders in patients with type 2 diabetes mellitus (T2DM) complicated by ischemic stroke. Methods: Two researchers independently searched 8 major databases and created a comprehensive database containing all randomized controlled trials (RCTs) that investigated the application of “blood-activating and stasis-removing” CPM in the treatment of stroke combined with T2DM until October 1, 2022. The collected data were compiled and organized in Excel. Quality assessment was performed using the Cochrane 5.3 bias risk assessment tool, and the network meta-analysis was conducted using R software. Results: A total of 12 articles were included in the final analysis, covering 4 types of CPM: Naoxintong Capsules (NXT), Tongmai Jiangtang Capsules, Tongxinluo Capsules (TXL), and Yindan Xinnaotong Soft Capsules. Among these, CPM formulations containing herbs with blood-activating and stasis-removing properties were the most commonly used. The results of the network meta-analysis are as follows: (1) the combination of 3 CPM formulations showed superior efficacy in improving total cholesterol levels compared to conventional Western medicine treatment (CT). In particular, Yindan Xinnaotong Soft Capsules + CT (surface under the cumulative ranking curve [SUCRA] = 97.24%) demonstrated the highest efficacy, followed by NXT + CT (SUCRA = 66.23%), and then TXL + CT (SUCRA = 55.16%). (2) TXL + CT treatment exhibited the most promising efficacy in improving triglyceride levels (P < .05), while the effects of the other 3 CPM formulations were not statistically significant. (3) In terms of improving low-density lipoprotein levels, NXT + CT (SUCRA = 82.27%) showed better efficacy than TXL + CT (SUCRA = 73.99%), while the effects of the other 2 CPM formulations were not statistically significant. (4) The combination of CPM formulations and CT resulted in a lower incidence of adverse reactions compared to CT (P < .05). Conclusion: The treatment of patients with T2DM complicated by ischemic stroke commonly involved the use of “blood-activating and stasis-removing” herbal medicines. These herbal medicines have shown effectiveness in regulating patients’ blood lipid levels. However, it is crucial to acknowledge that the analysis was influenced by variations in the number and quality of RCTs involving different CPM formulations. Therefore, additional validation through large-scale, high-quality RCT studies is required.

Background: Based on the main document of the Reporting Items of Practice Guidelines in Healthcare (RIGHT) statement, this study will aim to develop the reporting checklist applicable to the guidelines of Chinese patent medicine (CPM). Methods: According to the methodology recommended by the Enhancing the QUAlity and Transparency Of health Research (EQUATOR) network, three well-defined working groups were established, namely the coordination team, the advisory group, and the Delphi panel. The coordination team conducted a literature analysis of the already published CPM guidelines, the extensions of the RIGHT statement, and CPM related reporting specifications to initially form an initial item pool. The Delphi panel of multidisciplinary backgrounds will conduct two rounds of Delphi questionnaires to identify an extension item for RIGHT for CPM. These questionnaires will be sent to each Delphi panel member via email, and each member will independently fill out and provide comments within 10 working days of receiving the questionnaire. Finally, feedback will be provided to the coordination team and the post efficacy assessment of the already published clinical practice guidelines for CPM to determine the final items for RIGHT for CPM checklist. Dissemination: The extended version of the RIGHT for CPM checklist will be published in a peer reviewed journal. Conclusion: We hope that the upcoming RIGHT for CPM checklist provides detailed guidance for developers and users of CPM guidelines, further improving the quality of reports, and promoting the effective dissemination and implementation of CPM guidelines.

This paper presents the implementation of the integral and dynamic methodology in the scheduling and dynamic control of projects. For this purpose and using the above-mentioned methodology, a model which combines activity networks AON (activity on node), CPM, multimode execution and system dynamics is developed. The model is operationalized by developing two separate networks, i.e., a scheduling network on the one hand and the execution network on the other hand, in order to interact through a control loop. The proposal is validated using activity networks with 16 activities selected from MRCPSP of PSPLIB library. The model derived from the methodology has significant advantages in characteristic indicators of the project management. The paper concludes with a proposal of new combinations of tools, which, together with the methodology, can address problems of scheduling and control of projects with greater variability and complexity.

Dalam pembangunan suatu proyek tentu membutuhkan panduan dalam pelaksanaan yang tepat agar proyek dapat berjalan tepat waktu. Salah satu analisa mengenai manajeman waktu proyek adalah dengan menggunakan metode CPM. Dengan menggunakan meode CPM ini, rencana item pekerjaan proyek dapat diketahui yang mana pekerjaan kritis dan mana yang tidak kritis. Perhitungan CPM dilakukan berdasarkan perhitungan volume kegiatan dan analisa koefisien OH. Walaupun dalam pelaksanaannya sering terjadi perbedaan antara rencana dan realisasi, namun dengan menggunakan network diagram, kontraktor dan konsultan akan mengetahui mana pekerjaan yang bisa didahulukan dan mana yang bisa dilakukan belakangan. Pada proyek pembangunan gedung RSMH ini, direncakan hanya akan memakan waktu 135 hari. Namun dengan menggunakan diagram alir, akan diketahui berapa sebenarnya waktu minimal yang bisa dilakukan, yaitu sebanyak 119 hari.

Full textAbstract:
Abstract Memory suppression (MS) is essential for mental well-being. However, no studies have explored how intrinsic resting-state functional connectivity (rs-FC) predicts this ability. Here, we adopted the connectome-based predictive modeling (CPM) based on the resting-state fMRI data to investigate whether and how rs-FC profiles in predefined brain networks (the frontoparietal control networks or FPCN) can predict MS in healthy individuals with 497 participants. The MS ability was assessed by MS-induced forgetting during the think/no-think paradigm. The results showed that FPCN network was especially informative for generating the prediction model for MS. Some regions of FPCN, such as middle frontal gyrus, superior frontal gyrus and inferior parietal lobe were critical in predicting MS. Moreover, functional interplay between FPCN and multiple networks, such as dorsal attention network (DAN), ventral attention network (VAN), default mode network (DMN), the limbic system and subcortical regions, enabled prediction of MS. Crucially, the predictive FPCN networks were stable and specific to MS. These results indicated that FPCN flexibility interacts with other networks to underpin the ability of MS. These would also be beneficial for understanding how compromises in these functional networks may have led to the intrusive thoughts and memories characterized in some mental disorders.

The construction of residential houses in Pare City Kediri Regency experienced problems in the construction process was late from the predetermined schedule, which resulted in increased costs incurred. This project is located in Pare City, Kediri Regency, on a land area of 1200 M² with a size of 120 x 10 M first construction is a 20 x 8 M residential house. According to the agreed plan and a master schedule, this project is expected to be completed within 80 working days, and every day only work for 8 hours reality the implementation of this project, various factors affect the progress of the work. The percentage of actual cumulative progress until the 4th week of January is 97.42% of the 100% master schedule plan, there is a deviation of 2. 58 & it can be seen that the achievement of progress from the previous month indicates a continuous delay from the monthly plans made. One of the methods that must be used to design Network Planning is the Critical Path Method (CPM). The CPM method is used to plan, schedule, and control project activities that are deterministic or single time after evaluation data is obtained so that time and cost are more efficient and effective in calculating evaluation data using the CPM method. The project, which was initially completed in 103 days at Rp. 213,956,500 after being evaluated, and if there were no mistakes during project implementation, the normal time was 72 days at Rp. 160,276. 500 and then using the CPM method obtained an effective time of 52 days and an efficiency cost of Rp. 115,755,240.

Proses perencanaan hingga pengendalian proyek selama pelaksanaan pekerjaan konstruksi merupakan kegiatan penting dari suatu proyek. Keberhasilan atau kegagalan dari suatu proyek dapat disebabkan perencanaan yang tidak matang serta pengendalian yang kurang efektif, sehingga kegiatan proyek tidak efisien. Hal tersebut akan mengakibatkan keterlambatan, menurunnya kualitas, dan meningkatnya biaya pelaksanaan. Waktu kerja manajemen proyek dibatasi oleh jadwal yang ditentukan sehingga pimpinan yang terlibat dalam proyek harus dapat mengantisipasi perubahan kondisi yang terjadi. Metode CPM dapat digunakan untuk mengatur waktu penyelesaian proyek dengan lebih efisien dan efektif. Untuk dapat mengurangi dampak keterlambatan dapat diusulkan proses crashing dengan tiga alternatif pengendalian; penambahan tenaga kerja, kerja lembur, dan subkontrak. Percepatan durasi dilakukan pada pekerjaan- pekerjaan yang ada di lintasan kritis dan jumlah pemendekkan durasi tiap pekerjaan pada masing-masing alternatif disamakan. Dalam penelitian ini metode CPM ditujukan untuk mencari peluang dan probabilitas penyelesaian proyek. Batas waktu penyelesaian proyek adalah 120 hari, dan telah dilaksanakan kegiatan konstruksi hingga 127 hari, kemudian dilakukan percepatan durasi 118 hari. Disimpulkan dari segi waktu, metode CPM dapat mengalami percepatan selama 9 hari dibanding pelaksanaan pekerjaan dan mengalami percepatan selama 2 hari dibanding jadwal rencana.

Full textAbstract:
Dalam suatu proyek pembangunan, perencanaan kegiatan-kegiatan merupakan suatu aspek yang sangat penting untuk menghindari keterlambatan. Untuk itu diperlukan perencanaan dan penjadwalan yang matang agar pengerjaan proyek dapat dilakukan dengan seefisien dan seefektif mungkin. Dalam melakukan perencanaan kegiatan pekerjaan proyek, melakukan percepatan durasi proyek pada perencanaan awal merupakan suatu aspek yang penting juga untuk menghindari keterlambatan. Penelitian ini bertujuan untuk menganalisa estimasi waktu yang dibutuhkan untuk menyeleseaikan proyek pengantian Ball Mill di PT. Freeport Indonesia . Perhitungan penjadawalan proyek dilakukan dengan menggunakan metode Critical Path Method (CPM). Critical Path Method (CPM) merupakan model kegiatan proyek yang digambarkan dalam bentuk jaringan. Kegiatan yang digambarkan sebagai titik pada jaringan dan peristiwa yang menandakan awal atau akhir dari kegiatan digambarkan sebagai busur atau garis antara titik. Dalam penjadwalan diperlukan diagram network untuk menentukan urutan keseluruhan kegiatan. Untuk menyusun diagram network perlu diketahui kegiatan apa yang menjadi predecessor dan successor. Dari hasil perhitungan diperoleh lintasan kritis berada pada aktivitas A – C – D – F – G –H – I – L – M – N – O – P – R – S – T sampai Ya. Sementara itu, pekerjaan lain seperti pekerjaan B – J – K – Q tidak termasuk ke dalam lintasan kritis. Pekerjaan – pekerjaan tersebut tidak termasuk ke dalam lintasan kritis karena dalam perhitungannya memiliki waktu longgar. Dan pada perhitungan waktu menggunakan metode CPM durasi yang di dapatkan adalah 1215 jam yg berarti lebih cepat 29 jam dari jadwal yang dibuat PT X yaitu 1244 jam
