Simple Measuring

Fatigue is a common situation experienced by everyone, but until now a simple measuring tools universally accepted is not exist. Fatigue measurement instrument most widely used is an instrument-based questionnaire. This study used the Swedish Occupational Fatigue Index (SOFI) as one of the instrument to measure BRT driver’s fatigue. The aim is to evaluate physical mental, and shift work fatigue and provide an overview of fatigue levels experienced by the driver BRT on two different shifts. Hopefully it can be used for driver fatigue management by a company. The study was conducted for two different shifts (morning and afternoon), with a total participants are 30 drivers. Results showed that motivation level of shift 2-driver is lower after they finish their work compared to shift1-driver. In shift 1, generally available time to rest,socializing and hanging out with family is longer than available time for shift 2-driver. Perception of loss of energy after work is also higher in shift 2 compared to shift 1, especially the perception of feeling exhausted. Similar results were obtained in the physical aspect and the physical exertion and physical discomfort. Therefore we can conclude the work shift has affected fatigue level experienced by the driver's BRT, and shift rotation is suggested to help the driver to recuperate.

Gangguan tidur dapat dialami oleh setiap orang tanpa mengenal status sosial dan pendidikan. Diperkirakan setiap tahun terdapat 20% – 40% orang dewasa mengalami gangguan tidur dan 17% diantaranya mengalami masalah serius. Penelitian ini bertujuan untuk mengetahui hubungan antara penerapan pergantian waktu kerja (shift) serta beberapa faktor lain terhadap pola tidur pekerja di bagian produksi sebuah PT Enka Parahiyangan tahun 2008. Hasil penelitian menunjukkan bahwa kejadian pola tidur kurangbaik pada kelompok pekerja shift (67,1%) lebih tinggi daripada non-shift (32,9%). Selain itu, didapatkan odds ratio pola tidur pada pekerja shift 7,1 kali jauh lebih tinggi dibandingkan dengan non-shift. Faktor konsumsi kafeindan penggunaan obat tidur terbukti dapat memengaruhi pola tidur dan keduanya terbukti sebagai perancu. Disimpulkan bahwa penerapan shift (pagi, sore, malam) dapat menyebabkan kejadian pola tidur kurang baik lebih tinggi daripada non-shift sehingga perlu dilakukan peninjauan kembali penerapan rotasi shift oleh perusahaan. Pekerja disarankan agar menjaga jadwal tidur, menghindari konsumsi minuman berkafein, serta menggunakan obat tidur.Kata kunci: Pergantian waktu kerja, pola tidur, gangguan tidurAbstractSleeping disorder could be experiended by everyone without seeing social and education status. Approximately there 20% -40% adults with sleeping disorder per year, 17% of it having serious problems.

PurposeThe identification of fatigue status and early intervention to mitigate fatigue can reduce the risk of workplace injuries. Off-the-shelf wearable sensors capable of assessing multiple parameters are available. However, using numerous variables in the fatigue prediction model can elicit data issues. This study aimed at identifying the most relevant variables for measuring occupational fatigue among entry-level construction workers by using common wearable sensor technologies, such as electrocardiogram and actigraphy sensors.Design/methodology/approachTwenty-two individuals were assigned different task workloads in repeated sessions. Stepwise logistic regression was used to identify the most parsimonious fatigue prediction model. Heart rate variability measurements, standard deviation of NN intervals and power in the low-frequency range (LF) were considered for fatigue prediction. Fast Fourier transform and autoregressive (AR) analysis were employed as frequency domain analysis methods.FindingsThe log-transformed LF obtained using AR analysis is preferred for daily fatigue management, whereas the standard deviation of normal-to-normal NN is useful in weekly fatigue management.Research limitations/implicationsThis study was conducted with entry-level construction workers who are involved in manual material handling activities. The findings of this study are applicable to this group.Originality/valueThis is the first study to investigate all major measures obtainable through electrocardiogram and actigraphy among current mainstream wearables for monitoring occupational fatigue in the construction industry. It contributes knowledge on the use of wearable technology for managing occupational fatigue among entry-level construction workers engaged in material handling activities.

Society and the business world are paying more and more attention to the Circular Economy (CE) principles. The construction industry is no stranger to this issue, and the companies are transitioning towards sustainable production models. However, it is not easy to predict when and to what extent a company implements the CE. To measure this process, a scorecard, that includes the main Key Performance Indicators (KPIs) of the construction industry, related to the CE, was designed. Thus, the objective of this article is to design and test the CE-dashboard applicable to the construction industry. To do it, firstly, a literature review is performed. The next step is the selection of the KPIs collected in the literature, more suitable for reporting information about CE. Afterwards, a simulation based on the Monte Carlo technique performs. After multiple iterations, this method establishes the most probable KPI values as a result, which will be confronted with the limits used in the scorecard. With all this information, the dashboard emerges in Qlik software. Finally, a test of this dashboard takes place according to the information about KPIs from one of the leading Spanish companies (General Contractor (GC) building company). This step brings the validity of the created measurement instrument.

Organizational culture is currently considered a critical factor in achieving success in any business activity, including the implementation of the idea of sustainability. Sustainability-driven organizations incorporate a triple bottom line approach, which promotes the collateral achievement of companies’ environmental, economic, and social goals. The first bottom line is related to environmental sustainability. This bottom line should be facilitated by a pro-environmental organizational culture (PE culture). A company should strive to bring this culture to the highest possible level. Although in the literature on the subject some research on the factors that influence employees’ pro-environmental behavior have been presented, environmental sustainability in the context of organizational culture has received comparatively little attention. So far, the concept of levels of PE culture and the corresponding measurement instrument have not been developed. The aim of this paper is to present the concept of a pro-environmental organizational culture and its operationalization to support the achievement of sustainability goals. Operationalization is the process of determining the extension of a concept, which in turn transforms the concept into a metric. This paper presents a four-level concept of PE culture and a research instrument developed for the purpose of measuring the cultural level in organizations. The instrument was tested in a manufacturing company.

The aim of this study was to determine the elements of fatigue in occupations which constitute possible risk factors for the course of a pregnancy, and, in particular, that could cause premature birth. A total of 400 women with singleton pregnancies at ≥ 28 weeks’ gestation were enrolled in the study conducted at the Labor room,  Zenana Hospital , Jaipur. Patients reported the number of hours worked per week and answered specific questions designed to determine the following 5 sources of occupational fatigue: posture, work with industrial machines, physical exertion, mental stress, and environmental stress. Fatigue was quantified (0-5 index) according to the number of these sources positively reported. Simple and Mantel-Haenszel χ2 tests were used to test the univariate association and hypothesis of a linear trend between sources of occupational fatigue and spontaneous preterm delivery. Covariables were considered by multivariate logistic regression analysis. Women who did not work outside the home were considered separately from those who worked but did not report any sources of occupational fatigue.Result: women with sternous activity had higher occurrence of preterm birth. 18 % preterm mothers had high occupational fatigue index as compared to 75% term mothers, with p value <0.1,which was significant.

In der Schweiz leben zwischen 15000 und 16000 Menschen mit HIV/AIDS. Diese Population leidet unter einer Vielzahl von Symptomen und Beschwerden. Besonders schwerwiegend und häufig ist die Fatigue, welche gemäß aktueller Studien bei 20 bis 74% der HIV-infizierten Menschen auftritt. Das Symptom beeinträchtigt alle Aktivitäten des täglichen Lebens, das Empfinden körperlicher und mentaler Gesundheit sowie die Lebensqualität der Betroffenen stark. An der HIV-Sprechstunde des Universitätsspitals Basel, Schweiz, äußern viele Patienten und Patientinnen Beschwerden, die auf das Bestehen von Fatigue hinweisen, oder sprechen direkt über ihre starke Erschöpfung. Eine systematische Literatursuche wurde durchgeführt und ein evidenzbasiertes Praxisprogramm erarbeitet, um den Betroffenen eine angepasste Betreuung bieten zu können. Das Programm enthält die Elemente: Screening, systematisches Assessment, Interventionen und Beratung. Für das Assessment werden der adaptierte Global Fatigue Index und eine visuelle Analogskala eingesetzt. Die Patientinnen werden durch systematische Interventionen bei der Verbesserung ihres Selbstmanagements unterstützt. Ziel der vorliegenden Arbeit ist es, Pflegenden, die HIV-infizierte Menschen betreuen, eine Zusammenfassung der aktuellen Literatur bezüglich HIV-induzierter Fatigue zu präsentieren und die Elemente, den Ablauf sowie des Praxisprogramms darzustellen. Es kann davon ausgegangen werden, dass mit Hilfe des Praxisprogramms Menschen, die mit HIV/AIDS leben und unter Fatigue leiden, positiv beim Management dieses Symptoms ihrer chronischen Erkrankung unterstützt werden können.

Abstract. Fighter pilots may be exposed to extended flight missions. Consequently, there is increasing concern about fatigue. We investigated the effects of fatigue and cognitive performance in a simulated 11-hr mission in the 39 Gripen fighter aircraft. Five cognitive tasks were used to assess cognitive performance. Fatigue was measured with the Samn–Perelli Fatigue Index. Results showed that performance in the non-executive task degraded after approximately 7 hr. Fatigue ratings showed a matching trend to the performance in this task. Performance in tasks taxing executive functions did not decline. We interpreted that fatigue can be overridden by increased attentional effort for executive tasks but not for non-executive components of cognition. Participants underestimated their performance and metacognitive accuracy was not influenced by fatigue.
