Produktivitas kelompok kerja dalam proyek konstruksi sampai dengan saat ini relatif sedikit yang dipublikasikan. Terdapat banyak metode yang dapat digunakan untuk mengukur produktivitas tenaga kerja dilapangan. Analisis data dilakukan dengan cara matematis sederhana untuk mendapatkan besarnya produktivitas. Work sampling adalah salah satu metode pendekatan yang bisa digunakan untuk mengukur produktivitas dengan cukup mudah. Tujuan utama dari penelitian ini adalah untuk menganalisa produktivitas pekerja konstruksi pada pekerjaan beton bertulang. Selain itu, penelitian ini meninjau faktor-faktor yang mempengaruhi nilai produktivitas yang diperoleh dengan Metode Delphi yaitu dengan cara penyebaran kuisioner khusus ahli. Ukuran produktivitas yang didapat dari analisa ini adalah labour utilization factors (LUF). Penelitian ini dilakukan pada 4 proyek yang sementara melakukan pekerjaan beton bertulang. Penelitian ini melihat LUF berdasarkan waktu kerja (sebelum tengah hari dan setelah tengah hari). Hasil analisa work sampling menunjukan bahwa keseluruhan rata-rata LUF pada ke-empat proyek yang diteliti sebelum tengah hari adalah 46,98% sedangkan setelah tengah hari adalah 43,72%, persentase penurunan produktivitas rata-rata adalah 3,26%. Dari hasil penelitian mengindikasikan bahwa sebelum tengah hari pekerja lebih produktif dibanding setelah tengah hari. Analisa kuisioner menunjukan bahwa secara umum faktor yang berpengaruh sehingga adanya penurunan nilai produktivtas dalam hal ini karena setelah tengah hari, kelembaban udara yang tinggi dapat mempercepat rasa lelah tenaga kerja sehingga kondisi ini mempengaruhi pekerja dalam melakukan pekerjaan dapat lebih cenderung melakukan hal-hal yang tidak berkaitan dengan pekerjaan.

Published: July 2021

Suatu motor sinkron bila hendak digunakan sebagai generator sinkron, maka motor tersebut harus digerakkan oleh suatu penggerak mula pada kecepatan sinkron dan belitan rotornya harus dieksitasi melalui suatu catu daya DC. Dalam mengoperasikan motor sinkron sebagai generator sinkron adalah motor sinkron tidak memiliki penguatan medan atau eksitasi sendiri (self excitation), sehingga dibutuhkan catu daya tegangan DC yang dapat diatur untuk kebutuhan eksitasi medan rotor. Penguat atau eksitasi sendiri digunakan untuk menghasilkan eksitasi medan pada motor sinkron agar dapat beroperasi sebagai generator sinkron. Rangkaian catu daya DC dapat berupa rangkaian yang terpisah dari generator ataupun rangkaian yang tidak terpisah dalam hal ini tegangan keluaran (output) generator disearahkan dan digunakan sebagai catu daya eksitasi medan.Metode yang digunakan untuk menyelesaikan penelitian ini adalah riset dan pengembangan yaitu suatu metode yang dipakai untuk mengembangkan model, alat atau aplikasi tertentu berdasarkan proses penelitian.Dimana motor sinkron dioperasikan sebagai generator sinkron yang menggunakan penguat medan terpisah, dengan beban 0 – 210 Watt, ternyata yang terjadi adalah semakin besar beban yang diberikan pada generator, maka putaran generator dan tegangan keluaran yang dihasilkan dari generator mengalami penurunan, sehingga putaran generator harus distabilkan kembali pada putaran 1500 Rpm dan tegangan keluaran pada masing-masing fasa harus distabilkan pada 220 VAC, sedangkan dengan menggunakan penguat medan sendiri dengan beban 0 - 240 Watt, yang terjadi adalah tegangan eksitasi generator yang dihasilkan dari penguat medan sendiri (self excitation) akan tetap stabil, dan akan adalah putaran motor sinkron menurun dan harus distabilkan kembali pada putaran 1500 Rpm, tegangan eksitasi generator yang disuplai dari penguat medan sendiri tetap stabil. Sedangkan tegangan keluaran pada generator sinkron mengalami penurunan dari 252 VAC pada beban nol sampai 220 VAC pada beban maksimum dan arus mengalami peningkatan
Are We Already Living in Virtual Reality?

THOMAS METZINGER HAD his first out-of-body experience when he was nineteen. He was on a ten-week meditation retreat in the Westerwald, a mountainous area near his home, in Frankfurt. After a long day of yoga and meditation, he had a slice of cake and fell asleep. Then he awoke, feeling an itch on his back. He tried to scratch it, but couldn’t—his arm seemed paralyzed. He tried to force the arm to move, and, somehow, this shifted him up and out of his body, so that he seemed to be floating above himself. Gazing out into the room, he was both amazed and afraid. He heard someone else breathing and, in a panic, looked around for an intruder. Only much later did he realize that the breathing had been his.
At the time, in the early nineteen-eighties, Metzinger was a philosophy student researching the mind-body problem at the Johann Wolfgang Goethe-Universität. During the postwar years, Theodor Adorno and Max Horkheimer had made the university’s Institute for Social Research—the Frankfurt School—a center of neo-Marxist thought, and the campus remained a politically radical place. In Britain and America, philosophers, computer scientists, psychologists, and neuroscientists were working together to reconceive the mind as a purely physical system created by the brain. In Metzinger’s department, such theories were denounced as anti-human and “proto-fascist.” Metzinger considered himself a radical—he had waist-length hair, and was proud to have been teargassed while protesting the U.S. military—but also a rationalist. Immersing himself in the work of the Anglophone philosophers, he’d eventually become convinced that his soul was made by his brain. He was, therefore, doubly shocked by his out-of-body experience, which had seemed irrevocably real. Could materialism be wrong? Could consciousness exist immaterially, outside of the body? He admonished himself: “How arrogant I have been!”…

Le grandi imprese nel sistema produttivo italiano
Authors: Gallo Riccardo 
Published: July 2021

- Based on the analysis of the R&S-Mediobanca survey on multinationals, in 2006 the 17 Italians were small, but not "midgets", as a result of domestic and mostly transnational M&As. In the last ten years, their economic performance and financial structure have been always very sound and in line with the other multinationals. Their labour productivity has been lower than the average, but has improved since 1997. Italian manufacturing multinationals, however, show lower ratios than those of the utilities sector. Given the dire economic outlook worldwide, the Author believes that multinationals, Government and Unions in Italy should provide social support, mostly at labour level, and implement measures aimed at increasing size and productivity, fostering globalisation, and improving corporate governance.

L'evoluzione delle imprese multinazionali italiane e il ruolo del quarto capitalismo
Authors: Mutinelli Marco , Mariotti Sergio 
Published: July 2021

- The purpose of this article is to outline the evolution of Italian multinational firms during the 2001-2007 period. The descriptive statistics show that a selected group of medium-sized firms has outperformed the other Italian multinationals in terms of growth rate. The evidence is consistent with the hypothesis of the emergence in Italy of the so-called "fourth capitalism", as an alternative successful model to both the industrial districts and the large chandlerian corporations. Some limits of this structural evolution are also discussed.

La TV digitale terrestre: conservazione dell'esistente o innovazione verso la convergenza?
Authors: Preta Augusto 
Published: July 2021

- Even though competition among platforms has not yet clearly established a winner, digital TV has grown significantly everywhere. Technological developments have allowed new models for content consumption. User-generated content, on-demand services, catch up TV, PVRs which allow the creation of individual schedules and skipping commercials are disrupting the traditional passive mode of content consumption. Faced with these new models, some TV players are actually proactive in creating cross-platform synergies, in order to exploit their expertise and brand across a multitude of platforms, thus increasing their profits. The competitive scenario is undergoing substantial changes compared to the one we had grown familiar with over the last twenty years. Penetration of digital TV is moving ahead: in June 2008, there were nearly 100 million digital TV households in Western Europe, thus reaching 60% of European TV households. Satellite is still the most widespread digital access, but digital terrestrial television records the highest growth rates, thanks to the success reported in some of the biggest markets. After the Netherlands, also Finland and Sweden have completed the analogue switch-off. New platforms such as ADSL, FTTH are still struggling to conquer a place in the market. Although it is still a marginal platform, the IPTV is reporting interesting figures. Other services followed in Germany, Finland and the United Kingdom after the first commercial launch of mobile broadcast TV in Italy in June 2006,. Other services are expected to be launched with the EC supported standard DVB-H.

La definizione del costrutto di eterogeneitŕ e il legame eterogeneitŕ-performance
Authors: Lanza Andrea , Pellegrino Antonella , Simone Giuseppina 
Published: July 2021

Although heterogeneity has gained broad acknowledgement as a crucial phenomenon in the resource-based perspective, its relevance, whether as a source of inter-firm differences or of differences in firms' performance, has often been taken for granted rather been empirically assessed. Further, heterogeneity has been accepted as a self-explanatory concept instead of being studied and clarified as a construct for empirical research. Therefore, the goal of this paper is to define the heterogeneity construct and to eventually link the latter to firms' performances. A research on a 132 firms sample drawn from the Italian tool machine industry has been carried out to pursue this task. By means of a Structural Equation Model (LISREL) a 3-dimension construct has emerged; the heterogeneity construct dimensions are: contextuality, complexity and intertwinedness. The impact of heterogeneity on firms' performance has also been confirmed by means of LISREL. .

DESIGN, CONSTRUCTION AND TESTING OF A SMART STATIC AND DYNAMIC OBSTACLE WALKING STICK WITH EMF DETECTOR FOR THE BLINDS USING MCU AND CONTROLLING SOFTWARE
Authors: Sani Abdullahi Adamu  , Adamu Abdulkarim , Anas M. S. 
Published: July 2021

Smart static and dynamic obstacle walking stick with EMF detector is an upgraded smart stick designed for blind people for optimal navigation and electrical safety. An advanced blind stick prototype that allows visually challenged people to navigate walking paths and identify electronic gadgets with ease using modern technologies is hereby developed. The blind stick is integrated with ultrasonic sensor along with an EMF detector. This prototype first uses ultrasonic sensors to sense obstacles ahead using ultrasonic waves. On sensing obstacles, the sensor directs this data to the microcontroller. The microcontroller then processes this data and examine if the obstacle is close enough. If the obstacle is not that close the circuit does nothing. If the obstacle is close the microcontroller sends a signal to sound a buzzer. One more feature is that it allows the blind to detect the presence of EMF (electromagnetic field/electromagnetic waves) in the region he/she is, if there is, the microcontroller also sends a signal to a vibration motor (i.e. the output is in form of vibration), and if otherwise, the circuit does not trigger and thus, the vibration motor does nothing. The results obtained from the measurements have shown that this project work is optimally working and indeed operative.

Published: July 2021

Environmental pollution is the most important public health problem densely in populated areas in the developing countries and often the underlying cause of many diseases of public health importance. Noise pollution is an undesirable sound that interferes with wellbeing in the environment with significant effects. With the current rapid growth and technological advancement, noise pollution is increasingly becoming environmental menace that deserves appropriate attention in order to
mitigate its health effects. This paper aims to determine the sources, awareness and health effects of noise pollution in a typical Nigerian sub-urban population. Descriptive cross-sectional study using interviewer administered questionnaire and measurement of environmental noise using acoustic metre. Majority of the respondents (75.8%) were exposed to noise levels above the 55dB WHO safe noise level without health effects. Power generators, automobiles and grinding machines are the commonest sources of noise pollution in the studied environment amounted to a value of 55.8%, 40% and 35.8% respectively and to a lesser extent hawker (16.4%) and loudspeaker (9.6%) among others. Sleep disturbance, headache, and poor concentration were commonly reported effects of noise in the environment with magnitudes of 52.7%, 50.9%, 15.8% respectively. Anxiety (12.1%) and hearing disturbances (11.5%) were also common. Noise pollution associated health problems are common in the community with significant effects on the quality of life of the inhabitants. Stable power supply, effective legislation and improvement in living condition of the people are key to minimize noise pollution and avert its deleterious health effects

Published: July 2021

Experimental investigation requires materials, radiation sources, and test arrangements with a high monetary financial plan. Furthermore, radiation exposure involves people during the experiment. On the contrary, the simulation technique for examining radiation interactions is radio-logically safer, less timeconsuming, cost-effective, and applicable for all desired radiation sources. Through 48.86 mCi 662 keV Caesium-137 gamma-ray source; shielding experiment as well as simulation of it with MCNPX were performed for three shielding materials Lead, Copper, and Aluminum. These materials were placed in front of the gamma source and the emergent radiation was counted in a Geiger- Muller detector to understand the attenuation quality of these materials to each other. These courses of action were simulated utilizing the MCNPX code version 2.7.0 and the results likewise gave and looked at that of the experiment. There are huge similarities of shielding behavior between MCNPX simulation and experiments for the three absorbing materials. The modeled geometry of this MCNPX simulation could be used for future approaches of new designs and structures of radiation shielding, especially where no analogous experimental data exist
