This study developed an Intelligent Tutor for enhancing Think-Pair-Share in learning of Electrical Machines in Colleges of Education (Technical) in North East, Nigeria that will improve access to students and give them flexibility in learning. The study adopted a multi-method research design involving Research and Development (R & D) and Descriptive Survey research designs. The population of the study was 25 persons consisting of 10 lecturers of Electrical/Electronic Programme in Federal College of Education (Technical) Potiskum and Federal College of Education (Technical) Gombe, 15 industrial personnel, 5 each from Ashaka Cement, Bajoga, Savannah Sugar Plantation, Numan and Adama Beverages, Yola. Three research questions and three null hypotheses guided the study. The instruments were subjected to face and content validation by experts. The instrument, Intelligent Tutor Questionnaire for Electrical Machines (ITQEM) was then incorporated in the Intelligent Tutor (IT) for enhancing Think-Pair-Share in learning of Electrical Machines. Data collected from industrial personnel and lecturers’ validation were analyzed using mean and standard deviation, two-tail t-test was used for test of significance between the responses of industrial personnel and Electrical/Electronic lecturers at 0.05 level of significance. The findings of the study showed that three topics and 60 items were found to be appropriate for inclusion in the Intelligent Tutor. It was recommended among others that, since Research grants such as Tetfund NRF, Bench-work and PTDF should give priorities to scholars working on Intelligent Tutors and Artificial Intelligences in general to allow equal access for learners from all angles of the country which would in turn harnesses the untapped resourcefulness of the lecturers in Electrical Machines Principles of Operation.

Published: November 2023

Introduction The various changes that have occurred in recent decades have directly affected the health of workers, especially the psychosocial risks that cause physical or psychological illness. Psychosocial risk factors are important in the health care process, including how work is organized, time arrangements are determined, social relationships occur, and content and workload are structured, in terms of mental and social demands for each worker. Objective Verify the influence of work organization on the psychosocial risks of workers. Methodology A systematic review of the literature was performed using Methodi Ordinatio, which allowed the ranking of relevant works on the subject. Thirteen papers were selected for an in-depth analysis. Results The rate of mental and behavioral disorders is higher, respectively, in the Brazilian states of Rio Grande do Norte, Minas Gerais, Pernambuco, Rio de Janeiro, Distrito Federal, Santa Catarina, Rio Grande do Sul, Bahia, São Paulo and Paraná; with public administration workers being the most affected. It was demonstrated that the main causes of psychosocial risks are related to the working day (long hours and intense work rhythm), followed by lack of resources and problems of interpersonal relationships. Discussion and conclusion Measures to prevent psychosocial risks will depend on the situation with which the risk is associated, and organizational intervention in the prevention and management of these risks is of great importance.

Published: November 2023

Introduction The COVID-19 pandemic led to the adoption of paramount measures to detect SARS-CoV-2 infection and prevent its spread, causing anxiety in the general population. Health professionals have been considered one of the most vulnerable groups for mental health problems, as observed in past epidemics. The present study aimed to assess the anxiety in primary healthcare professionals during the COVID-19 pandemic and identify the factors that influenced it. Methodology This cross-sectional study was performed via an online anonymous survey, disseminated primarily through social networks and institutional mailing lists, between March 29th and April 5th 2020, applied to primary healthcare professionals in mainland Portugal. Anxiety levels were obtained by applying the Beck Anxiety Inventory. Logistic regression analyses were conducted to identify factors associated with anxiety levels. Results The study included 696 participants, of which 61.9% were physicians, 84.8% were women and 43.8% presented mild to severe levels of anxiety. Factors such as personal history of previous mental health disorders (p<0.001), having a family member with risk factors for SARS-CoV-2 complications (p=0.012) and being an administrative clerk (p=0.014), showed to relate with higher levels of anxiety. On the other hand, the existence of a workspace contingency plan was associated with lower anxiety levels (p=0.048); nevertheless, 6.9% considered it inadequate, mainly due to inappropriate protective equipment for professionals (79.6%). Conclusion This study highlights a high prevalence of anxiety among health professionals and reinforces the need of, in future pandemics, promoting the adoption of adequate measures to protect their mental health and, ultimately, safeguard the quality of patient care. Keywords: COVID-19, pandemic, anxiety, health personnel, occupational health, occupational medicine.
EXPERIMENTAL INVESTIGATION OF SCOUR DOWNSTREAM OF A C-TYPE TRAPEZOIDAL PIANO KEY WEIR WITH STILLING BASIN
Authors: Qasim Rdhaiwi Ali , Khoshfetrat Ali , Fathi Amirhossein
Published: November 2023

In recent years, engineers have focused on finding a solution to reduce scouring downstream of piano key weirs. Piano key weirs have high efficiency in flood flow and a higher discharge coefficient. In this research, a type C trapezoidal piano key weir with a type 1 stilling basin was used. Three discharges and three water depths were also used. The results showed that the existence of the stilling basin reduces scour. In the weir with the stilling basin, the maximum scour depth is reduced and the scouring hole becomes more elongated. The maximum distance of the scouring depth increases compared to the toe of the weir. The maximum scour depth and the maximum scour depth distance in the weirs with the stilling basin are about 63.4% less and 20.4% more, respectively than in the weirs without the stilling basin. Additionally, by increasing the flow rate and decreasing the depth of the downstream flow, the amount of scour increases.
Are Physical Activity Levels in Childhood Associated with Future Mental Health Outcomes? Longitudinal Analysis Using Millennium Cohort Study Data
Authors: Karvelyte Ieva
Published: November 2023

The rising prevalence of mental health conditions among children and young adults accelerated by the COVID-19 pandemic emphasises the urgent need to address this issue effectively. A potential avenue for early diagnosis lies in physical activity patterns as individuals with mental health conditions often move less than the general population. This paper utilises Millennium Cohort Study data to investigate the relationship between childhood physical movement patterns, and mental distress and wellbeing outcomes in late adolescence. By controlling for a range of factors of both cohort members and their parents, the study employs well-adjusted logistic and linear regressions to assess the hypothesis. Objective physical movement data is collected with accelerometers, while mental distress is measured using the Kessler K6 scale and mental wellbeing using the Warwick–Edinburgh Mental Wellbeing Scale. The findings of the study suggest no significant association between raw physical movement and mental distress; however, there is suggestive evidence of a weak positive association with mental wellbeing. In addition, the study found that lower exercise levels at age 7 were associated with an increased likelihood of mental distress at age 17, highlighting the potential impact of exercise habits on mental health in adolescence. Overall, these findings suggest that raw physical activity data may be a better predictor of specific mental health outcomes, such as those assessed by the Strengths and Difficulties Questionnaire in similar studies. The paper offers recommendations for future research – such as using self-reported questionnaires to contextualise quantitative physical movement data – and a more comprehensive analysis of the cognitive and mental implications.

Published: November 2023

Tolosa-Hunt Syndrome is an idiopathic granulomatous inflammatory disease of the cavernous sinus, superior orbital fissure, or orbit which is manifested by ocular pain and ophthalmoplegia. Granulomatous inflammation of the dural wall of the cavernous sinus and/or superior orbital fissure is the basis of the pathological process. The disease is clinically manifested by orbital pain, diplopia, exophthalmos, and/or oculomotor abnormalities. The syndrome is also called painful ophthalmoplegia with a key symptom being neuropathic periorbital or retro-orbital pain, and paresthesias along the first branch of the trigeminal nerve. We present a case of this syndrome. The patient was administered hormonal therapy, Medrol at a daily dose of 1 mg/kg body weight/day intravenously for five days, with subsequent transition within a month to oral Medrol. The pain in the eye completely relieved and restoration of normal ocular motility was observed in the presence of hormonal therapy. Tolosa-Hunt syndrome is a clinical diagnosis of exclusion (i.e., it is diagnosed after excluding other causes of painful ophthalmoplegia).
Lessons from the American Innocence Projects
Authors: Roach Kent
Published: November 2023

This review essay examines recent trends in American wrongful conviction scholarship. Despite calls for a ‘criminology’ of wrongful conviction, narrative about actual cases remains important. The two books reviewed explore the ambiguities and challenges of innocence work by examining cases where the authors represented wrongfully convicted persons without DNA evidence. The books both critique restrictions on post-conviction relief in the American Federal Courts. These restrictions are assessed as examples of American ‘extra-legalism’ where a very complex legal system frequently produces unjust results and fails to provide redress and accountability for injustice. The role of equality and non-discrimination norms in wrongful convictions discourse are also assessed. Valena Beety’s call for a substantive and social justice approach focused on ‘manifest justice’ and fundamental reforms to the American criminal justice system is compared to Daniel Medwed’s more narrow focus on factual innocence. It is argued that Beety’s more ambitious approach is normatively superior and more easily applied outside the distinct context of American mass imprisonment and extra-legalism.
Papiloma ocular: una mirada profunda a la enfermedad ocular y su manejo
Authors: Lilliana Marcela Lilliana Marcela , González Alfaro Fernando José , Salazar Porras Daniela
Published: November 2023

El papiloma ocular es una enfermedad que afecta al ojo y se origina a partir de la infección del virus del papiloma humano (VPH) en la conjuntiva, una membrana que recubre la parte blanca del ojo y los párpados. Como resultado de esta infección viral, se forman protuberancias o verrugas en la superficie ocular.

Los síntomas del papiloma ocular pueden variar en intensidad y presentación, pero comúnmente incluyen enrojecimiento ocular, irritación, sensación de cuerpo extraño, picazón y visión borrosa. Estas protuberancias pueden ser únicas o múltiples, y su tamaño puede oscilar desde pequeñas lesiones hasta crecimientos más grandes.

El tratamiento del papiloma ocular generalmente implica la eliminación quirúrgica de las verrugas o protuberancias. Para ello, se utilizan diversos métodos como el raspado, la escisión con láser o la crioterapia (congelación), siendo la elección del método dependiente del tamaño, la ubicación y las características específicas de las lesiones oculares. En algunos casos, se pueden recetar medicamentos tópicos para reducir la probabilidad de recurrencia de las verrugas.

Es importante destacar que el papiloma ocular puede presentar un riesgo potencial de transformación maligna. Algunas verrugas pueden volverse cancerosas y desarrollar un carcinoma de células escamosas conjuntival. Por esta razón, se recomienda realizar un seguimiento periódico después del tratamiento, a fin de detectar cualquier signo de recurrencia o cambio maligno.

En cuanto a la prevención del papiloma ocular, se centra en evitar la exposición al virus del papiloma humano. Esto implica practicar sexo seguro y evitar el contacto directo con las lesiones de la piel o membranas mucosas de personas infectadas. Además, mantener una buena higiene ocular y evitar compartir productos de cuidado personal relacionados con los ojos, como toallas o cosméticos, puede contribuir a la prevención de la enfermedad.

A Checkerboard of Ethnoracial Violence
Authors: Wacquant Loïc
Published: November 2023

Ethnoracial violence is a dynamic and multilayered phenomenon whose definition is at stake not only in academe but also in reality itself. It comes in two varieties, expressive and instrumental, when it serves to buttress the other four elementary forms of racial domination, namely, categorization, discrimination, segregation, and seclusion. I point out that the phenomenon is relatively rare and burdened with heavy moral baggage. I introduce distinctions based on directionality (vertical, horizontal), scale of the actors involved (individual, group, or state), degree of spectacularization, and type of ethnic classification system (categorical, gradational). The imperial domain offers an especially fruitful terrain for the comparative investigation and theoretical elaboration of the dynamics of racialization, violence, and the state. Students of human brutality in history should join hands with comparative scholars of race to throw new light on their explosive intersection.
On Violence, Race, and Social Theory
Authors: Meghji Ali
Published: November 2023

In this article, I offer an engagement with Wacquant's checkerboard of ethnoracial violence. Drawing on material from the digitalized W. E. B. Du Bois archive, I focus on two theses of Du Boisian thought that I believe can enrich Wacquant's theorization of ethnoracial violence. In particular, I highlight how Du Bois emphasized (1) the process by which colonial violence gets (mis)recognized as nonviolence; and (2) how ethnoracial violence connects to capital accumulation as an essentially profitable enterprise. Bringing Du Bois’ work into the picture, I invite Wacquant to consider the relationship between ethnoracial violence and racial capitalism and to engage in a fuller discussion about the struggles in social space over the very definition of violence itself. I conclude by questioning how we might connect Wacquant's contemporary theorization with the work of intellectuals—such as Du Bois—who have put ethnoracial violence at the center of their concerns.
Gender diversity in neurosurgical training: an analysis of trends and resident program characteristics
Authors: Fassina Grace R. , Nguyen Emily E. , Shi Helen H. , Spence Caple A.
Published: November 2023

OBJECTIVE

Recent trends have shown more women entering neurosurgery, but large gender gaps in the number of female trainees continue to persist. A previous study on the gender diversity of residents and faculty in neurosurgery training programs found that only 18.2% of residents and 8.7% of faculty at neurosurgical training programs were female. The goal of this study was to better understand program characteristics that may affect the recruitment of female residents and the gender composition of neurosurgery residency programs.

METHODS

The authors assessed publicly available information on websites and social media from 116 Accreditation Council for Graduate Medical Education (ACGME)–accredited neurosurgery residency programs from the 2022–2023 academic year. Data collected on residents included gender and postgraduate year (PGY), geographic region, accreditation year, and complement size for programs. The authors analyzed the distribution of female residents at each program and compared accreditation year, program size, program geographics, PGY, and acceptance rates.

RESULTS

There were 1602 residents across the 116 programs included in this study: 1223 (76.3%) male and 379 (23.7%) female residents. The gender distribution of female residents showed 29 programs had 30% or more female residents, 50 programs had between 16% and 30%, and 37 had fewer than 16%, including 8 with none. There were significantly more PGY-1 than PGY-7 female residents (28.9% vs 16.4%, p < 0.01). Programs with ACGME accreditation before 1970 had significantly higher percentages of female residents (26.0%) compared with those accredited after 1970 (18.2%, p < 0.01). Program size was associated with a higher percentage of female residents (large = 25.2%, medium = 24.9%, and small = 19.6%), although the results were not significant. The distribution of female trainees across five geographic regions of the United States was fairly even: Northeast (24.5%), West (25.2%), South Atlantic (23.1%), South Central (21.8%), and North Central (21.2%). Residency acceptance rates were similar between genders.

CONCLUSIONS

The underrepresentation of women in neurosurgery residency programs remains a significant issue. While some programs have achieved higher female representation than the overall average proportion of female neurosurgery residents, many still fall short. There are twice as many female PGY-1 compared with PGY-7 residents, suggesting increased recruitment over the past few years. Programs with longer accreditation histories have significantly higher proportions of female residents. Larger program size can also play a role in attracting more female residents, but geographic location did not impact gender composition of resident cohorts in this study.
The role of limited access to students from more diverse nonfeeder medical schools in creating diversity inequities in neurosurgical residency
Authors: Klein Benjamin R. , Sowah Mareshah N. , Levi Allan D.
Published: November 2023

OBJECTIVE

Improving racial/ethnic diversity in neurosurgery is a long-standing issue that needs to be addressed. The positive correlation between medical students with home neurosurgery programs and successful matriculation into neurosurgical residency is well documented. In this article, the authors explored the relationship between decreased racial/ethnic diversity in neurosurgery residency programs and racial/ethnic diversity in feeder medical schools.

METHODS

The authors conducted a standardized review of the literature to evaluate potential causes for decreased racial/ethnic diversity within neurosurgery. Additionally, they calculated the average enrollment of Black/African American medical students at the top 5 neurosurgery feeder medical schools (determined by Antar et al. following the 2014–2020 match cycles) during the 2021–2022 school year and compared that with the enrollment at US allopathic medical schools with the highest enrollment of Black/African American students. They also compared these two groups in terms of how many students they sent into neurosurgery residency programs from 2014 to 2020. For each of these comparisons, the authors conducted a two-sample t-test to evaluate correlation between these two variables.

RESULTS

There was significantly lower average enrollment of Black/African American students at the top 5 feeder medical programs into neurosurgery residency (80.6 ± 8.32) compared with the top 5 medical schools with Black/African American enrollment in the 2021–2022 school year (279 ± 122.00, p < 0.05). The authors also found a significant increase in the number of students entering neurosurgery residency programs between the top 5 feeder medical programs into neurosurgery residency (30.8 ± 6.06) and the top 5 medical programs for Black/African American enrollment (6 ± 6.16, p < 0.0001).

CONCLUSIONS

In this paper, the authors examined, through a Black/African American lens, the role of racial/ethnic diversity in medical schools that historically send many students to neurosurgery residency. This study sought to provide insight into this problem and examine how Black/African American students from nonfeeder medical schools are disproportionately affected. The authors’ findings suggest that the lack of Black/African American representation in neurosurgery is strongly correlated with the diversity efforts of medical schools. Lastly, the authors highlight the University of Miami’s Summer Research Scholarship in Neurosurgery for Medical Students and other programs as potential solutions to combat the lack of racial/ethnic diversity in neurosurgery.
Compression and Decompression Using Deep Neural Network
Authors: Wei Jinxin , Hou Zhe
Published: November 2023

An auto-encoder which can be split into two parts is designed. The two parts can work well separately. The top half is an abstract network which is trained by supervised learning and can be used to classify and regress. The bottom half is a concrete network which is accomplished by inverse function and trained by self-supervised learning. It can generate the input of abstract network from concept or label. It is tested by tensorflow and mnist dataset. The abstract network is like LeNet-5. The concrete network is the inverse of the abstract network. A picture can change to label that is compression, then change it back from label that is decompression. So compression and decompression can be realized by the autoencoder. Through test, the absolute function can do generation task well, while the leaky relu function can do classification task well. Lossy compression can be achieved by abstract network and concrete network with absolute function. With one-hot encoding, the compression ratio is 5.1% when decompression quality is good. With binary encoding, the compression ratio is 2% when decompression quality is ok. The mean PNSR of five pictures is 19.48 dB. When jump connection and negative feedback are used, the decompression performance is good. The mean PNSR of five pictures is 29.86 dB. The compression ratio is 56.1%.

Published: November 2023

Understanding the perceptions and experiences of a community regarding disasters is crucial in effectively planning and implementing disaster strategies. There are two known approaches to analyzing perceptions, qualitative and automated approaches for thematic analysis. This paper aims to investigate the strengths and limitations of the mentioned approaches. Thus, using both approaches, this study analyzed data from a focus group discussion about disaster risk reduction and management and climate change adaptation conducted in a typhoon-prone city in Legazpi City, Philippines. An inductive-deductive approach for the qualitative method while a language model-assisted approach for the automatic method of extracting prominent themes from the collected responses. The results show (dis) similarities regarding themes obtained from the two approaches, specifically the emphasis on concerns about the proper distribution of relief goods and donations, proper early monitoring of potentially powerful typhoons, and other forms of threat, including politically motivated ones. From these findings, we conclude the importance of incorporating a combined manual and automatic approach for thematic analysis of natural language.
Sentence Similarity Using Modified Latent Semantic Analysis and Semantic Relations
Authors: NishyReshmi S  , Shreelekshmi R
Published: November 2023

In this paper, we propose a method for finding the similarity of sentence pairs. The method combines two modules – a modified Latent Semantic Analysis and a semantic similarity computation. The proposed method makes use of the syntactic structure and semantic information contained in the sentence pairs. The syntactic structure in the form of dependency triplets is extracted and a semantic similarity calculation is carried out. The semantic similarity between words is calculated using Wu & Palmer similarity measure and Wordnet synonym relation is used in modified Latent Semantic Analysis. The proposed method is evaluated on the Microsoft Research Paraphrase Corpus dataset and the accuracy obtained on the dataset is 73.19% which is better than existing statistical and zero shot domain adaptation methods. The proposed method is also tested on Li et al. text similarity dataset and the Pearson correlation coefficient of 0.9021, Spearman correlation of 0.9103 and mean deviation of 0.105 with the human judgement show that the method outperforms state-of-the-art methods.
Research on a Symbolic Cluster Analysis Algorithm Approaching to the Optimal Value
Authors: Zang Fang
Published: November 2023

Nowadays, there is a large amount of symbolic data in various fields, and people can fully utilize these symbolic data for clustering, providing a better foundation and direction for data mining and analysis. Currently, clustering algorithms for symbol data have emerged one after another, but there are still shortcomings in computational cost and algorithm robustness. Therefore, it is urgent to study an algorithm with stable clustering results, less time consumption, and low I/O overhead. The following proposes a symbolic cluster analysis algorithm that approaches to the optimal value. It reduces the size of the original data by generating a symbolic association graph from a large number of symbolic data samples, effectively solves the problem of high computing costs caused by the huge amount of data, and proves the clustering effect of the algorithm through empirical analysis.
Usage of Machine Learning Methods for Cause-Effect Graph Feasibility Prediction
Authors: Krupalija Ehlimana , Cogo Emir , Pozderac Damir , Ali Al Zayat Aya , Bešić Ingmar
Published: November 2023

Cause-effect graphs (CEGs) are usually applied for black-box testing of complex industrial systems. The specification process is time-consuming and can result in many errors. In this work, machine learning methods were applied for predicting the feasibility of CEG elements. All information was extracted from graphs contained in CEGSet, a dataset of CEGs. The data was converted to two different formats. The Boolean features format represents relations as separate data rows, whereas the Term-Frequency times Inverse-Document-Frequency (TF-IDF) format represents graphs as data rows. Eight machine learning models were trained on this data. The results of testing by using the 80–20 holdout method indicate that important information is lost when converting the graphs to the TF-IDF format, whereas the Boolean feature format enables 100%-accurate predictions of ensemble methods. The achieved results indicate that pre-trained models can be used as help for domain experts during the CEG specification process.

Perubahan Nilai Kekuatan Tarik Pada Hasil Pengelasan Friction Stir Welding Aluminium 2024 - T3 Yang Menggunakan Perlakuan Transient Thermal
Authors: Pujono Pujono
Published: November 2023

Paduan aluminium seri 2xxx merupakan paduan Al-Cu dengan sifat mekanis yang cukup tinggi, yaitu tegangan tarik maksimum 470 MPa dan tegangan luluh 280 MPa. Paduan aluminium ini merupakan paduan aluminium yang memiliki mampu las rendah sehingga salah satu metode untuk meningkatkan kekuatan las adalah dengan menerapkan proses pengelasan friction stir welding (FSW). Salah satu perlakuan yang tepat dalam pengelasan FSW pada aluminium adalah memberikan pemanasan lokal di daerah sekitar las, dengan posisi pemanas berada didepantool las atau perlakukan transient thermal. Tujuan dari penelitian ini adalah untuk mengetahui perubahan nilai kekuatan tarik pada paduan aluminium dengan pengelasan FSW tanpa pemanas dan pengelasan FSW dengan tambahan pemanas (transient thermal). Metode Penelitian dilakukan dengan pengelasan paduan aluminium plat 2024-T3 menggunakan teknik FSW tanpa pemanas dan teknik FSW dengan perlakuan transient thermal. Perlakukan panas (transient thermal) dilakukan dengan meletakkan pemanas di depan tool las. Kecepatan pengelasan FSW ditentukan adalah 12 mm / menit dan 1200 rpm. Hasil penelitian menunjukkan bahwa kekuatan tarik tertinggi ultimate tensile strength (σmax) diperoleh dari spesimen dengan las FSW tanpa perlakuan panas yaitu adalah 297,28 MPa. Perlakuan transient thermal dengan posisi heater di depan alur las menyebabkan penurunan nilai kekuatan tarik. Penurunan nilai tegangan tarik maksimum terjadi sekitar 32,2%, sedangkan nilai tegangan luluh terjadi penurunan dari spesimen tanpa pemanasan dengan spesimen yang menggunakan pemanasan (transient thermal) yaitu sebesar 32,5%. Hasil pengujian tarik juga menunjukkan bahwa terjadi patah getas dan lokasi patah berada pada daerah las.

Manajemen proyek dimulai dari kegiatan perencanaan hingga pengendalian yang didasarkan atas input-input seperti tujuan dan sasaran proyek, informasi dan data yang digunakan, serta penggunaan sumber daya yang benar dan sesuai dengan kebutuhan yang diperlukan. PT.Sinar Jembar Pratama merupakan salah satu perusahan kontraktor yang khususnya bergerak di bidang sipil konstruksi. Seorang manager proyek dapat mempunyai tanggung jawab untuk menangani lebih dari satu proyek yang berjalan dalam waktu yang bersamaan. Untuk melakukan tugasnya, seorang manager proyek harus memantau pelaksanaan kegiatan proyek-proyek secara bergantian. Hal tersebut dapat menimbulkan masalah, yaitu ketika manager proyek tidak bisa datang ke lapangan untuk memonitor pelaksanaan kegiatan proyek, sehingga kegiatan pemantauan pelaksanaan proyek dan koordinasi dalam proyek di lapangan tidak berjalan maksimal. Selain itu kesulitan lain juga dialami estimator proyek untuk mengetahui anggaran biaya yang tersimpan dalam arsip. Berdasarkan dengan pe masalah yang sudah dijelaskan, maka penulis bermaksud mengembangkan sistem informasi manajemen proyek konstruksi yang mampu  membantu dan mempermudah peusahaan khususnya bagi  manager proyek  dalam memonitor progress proyek dan estimator proyek dalam meyusun rencana anggaran biaya. Dari hasil pengujian yang telah dilakukan oleh peneliti, maka dapat disimpulkan bahwa sistem manajemen proyek dapat membantu site manager, manajer proyek, direktur dan konsultan pengawas dalam memonitor progresss proyek dan estimator  proyek dalam mengelola penyusunan rencana anggaran biaya, sehingga sistem yang dibuat dapat menyelesaikan masalah-masalah yang dihadapi perusahaan tersebut.

Tahun 2012 Jurusan Teknik Sipil Politeknik Negeri Semarang membuka program studi baru yaitu program studi D4 Jalan dan Jembatan Kereta Api. Pada semester 5 ada mata kuliah Uji Bahan Bangunan 3, dimana pada mata kuliah ini terdapat alat uji Cabut Rel dari bantalan, yaitu menguji kekuatan penambat rel. Laboratorium Bahan Bangunan jurusan Teknik Sipil Politeknik Negeri Semarang sejak tahun 2015 telah memiliki alat uji cabut penambat rel jenis clip (pendrol). Ternyata dalam pelaksanaan uji, dibutuhkan alat bantu / tambahan untuk memasang pendrol karena pendrol harus dipasangkan pada bantalan, kesulitan yang dihadapi adalah bantalan tempat memasang pendrol merupakan bantalan beton tunggal berdiri sendiri sehingga tidak stabil kedudukannya, maka pemasangan pendrol dengan dipukul menggunakan palu besar tidak bisa dilakukan. Disisi lain memasang pendrol dengan alat yang telah dibuat susah dilakukan karena kelemahan pada bagian konstruksi pendorongnya. Karena kondisi tersebut mengakibatkan mahasiswa mengalami hambatan dalam pelaksanaan praktikum, Maka penelitian ini akan mengkaji konstruksi pendorong alat pasang pendrol. Penelitian ini fokus pada bagian konstruksi pendorong, penelitian ini dilakukan untuk meningkatkan kinerja alat, sehingga akan berdampak pada kualitas dan efisien waktu pelaksanaan proses belajar mengajar laboratorium Bahan Bangunan Program Studi Perancangan Jalan dan Jembatan. Hasil akhir pada penelitian ini adalah terwujudnya alat untuk memasang pendrol yang bekerja sempurna.Alat yang dirancang pada penelitian ini didasarkan pada perancangan alat sebelumnya dan disempurnakan berdasar pertimbangan fungsi yang optimal namun simple dan mudah diaplikasikan dalam praktek.
