Abstract: This research is the application of quality control tools within the scope of increasing productivity of the packaging department at PT. XYZ. This study aims to determine the factors causing the decline in productivity in the packing warehouse area. The first step of the research is to analyze the input data using a Pareto diagram. The source of problems that occur from outside the packing area are four cases, namely Canceled Delivery, Part Received Without Documents, No Stock and Quality Issue. Meanwhile, for problems that occur from internal packaging, there are two, namely the No Packaging Box and No Operator Entering. By using the Ishikawa diagram and 5 whys, the sources of problems that occur in the internal packing area are analyzed further and obtained several sources of problems that contribute greatly to the decline in productivity in the packaging area, namely the process of purchasing packaging boxes which takes quite a long time and long working hours from the packaging team. Some of the solutions for internal problems offered include changing the carton box procurement process using blanket orders, upgrading the team leader's capabilities with order and budget monitoring capabilities, proposing changes in the production flow for semi-finished goods and a proposal to create a temporary warehouse for semi-finished goods. Abstrak: Penelitian ini merupakan penerapan dari alat pengendalian qualitas dalam lingkup peningkatan produktivitas bagian pengepakan di PT. XYZ. Penelitian ini bertujuan untuk mengetahui faktor penyebab penurunan produktivitas diarea gudang pengepakan. Langkah awal penelitian dengan menganalisa data masukan menggunakan diagram Pareto. Sumber masalah yang terjadi dari luar area pengepakan ada empat kasus yaitu Pengiriman Dibatalkan, Part Diterima Tanpa Dokumen, Stock Tidak Ada dan Ada Issue Kualitas. Sementara untuk masalah yang terjadi dari internal pengepakan ada dua yaitu Box Pengemas Tidak ada dan Operator Tidak Masuk. Dengan menggunakan diagram Ishikawa dan 5 whys , sumber masalah yang terjadi di internal area pengepakan dianalisa lebih lanjut dan diperoleh beberapa sumber masalah yang berkontribusi besar terhadap penuruan produktivitas di area pengepakan yaitu proses pembelian box pengemas yang memakan waktu cukup lama dan jam kerja yang panjang dari tim pengepakan. Beberapa solusi untuk permasalah internal yang ditawarkan antara lain merubah proses pengadaan karton box dengan menggunakan blanket order, mengupgrade kemampuan team leader dengan kemampuan order dan budget monitoring, mengusulkan perubahan alur produksi untuk barang-barang setengah jadi serta usulan untuk membuat gudang sementara untuk barang setengah jadi.

AbstractThe tools for quality management are used for quality improvement throughout the whole Europe and developed countries. Simple statistics are considered one of the most basic methods. The goal was to apply the simple statistical methods to practice and to solve problems by using them. Selected methods are used for processing the list of internal discrepancies within the organization, and for identification of the root cause of the problem and its appropriate solution. Seven basic quality tools are simple graphical tools, but very effective in solving problems related to quality. They are called essential because they are suitable for people with at least basic knowledge in statistics; therefore, they can be used to solve the vast majority of problems.

Quality Tools

Purpose Some manufacturing and service organizations have made efforts to work on continuous improvement in the form of Kaizen, lean thinking, Six Sigma, etc. The elimination of problems and waste (MUDA for the Japanese) plays a fundamental role in the reduction of operational costs and quality rejections of finished products both internally in the organization and in the supply chain. Some of these efforts use quality control tools to remedy it. Kaoru Ishikawa proposes seven basic quality tools. In this group of quality tools is the cause-and-effect diagram (CED), also known as “The Fishbone” and “Ishikawa diagram”. Exploring this questioning can shed light on the first indications to ratify the arguments of Ishikawa and Deming, that the main problems of companies are found in their processes and perhaps, in a deep way, in some of these cornerstone root causes that have to do with the way organizations are managed. The purpose of this study is to investigate cornerstone root causes through the application of CEDs in 40 Mexican companies that began an effort to improve some of their organizational processes. Design/methodology/approach An exploratory qualitative study was conducted. As a research strategy, the case study method was applied. Using theoretical sampling, the Ishikawa diagrams of 40 companies were analyzed, and 24 semi-structured interviews in depth were conducted. Findings The results of this research confirm the main research question: Are there cornerstone root causes that give way to one or several problems or effects of problems in organizations regardless of their sector? In other words, there were at least seven typical patterns that show the first signs of cornerstones root causes in organizations. Research limitations/implications The method itself is a limitation; 40 case studies are not enough to generalize the results. In addition, the research was conducted only in a single Latin American country; in some cities of Mexico. However, 60 per cent of these companies are multinationals. Practical implications This paper is fundamental to delve into the cornerstones causes that give rise to the problems of organizations of the twenty-first century. The authors understand that these are the first indications, and that they cannot be considered a conclusion of these causes. However, this first theoretical sampling presents a first light on the subject. Originality/value The study contributes to the limited existing literature on total quality management and Kaizen in quality control tools and subsequently disseminates this information to provide impetus, guidance and support toward improving the problems of the organizations of twenty-first century.

Melbourne is one of the liveliest cities in the world. It has a well efficient transport system, supported by a vast network of trams. Therefore, the mental health and stress level of the tram drivers plays a crucial role in the safety of the passengers. The issue of fatigue and drowsiness in the tram drivers are mostly due to their work-time and the most common thing is that the drowsiness occurs during the work time itself. This drowsiness is a risk for everyone including those who are not travelling in the tram. The current system that is used to prevent the drivers from falling sleeping is called the deadlock system. In this system the driver keeps his foot on a pedal at all times. Whenever the driver lifts his foot from the pedal the tram stops moving. Considering the technologies that are currently implemented in the vehicles seems to be insufficient. More over the driver gets uncomfortable when he keeps his foot onto the lever for a long time during long working hours. We have used OpenCV in python to create a program which monitors the eyes of a person and ensures that they keep the eyes open. The developed algorithm uses python libraries to detect any abnormality in the time interval between blinks and the extent of openness of the driver’s eyes. When an abnormality is detected the driver receives an alarm on his phone indicating driver drowsiness.

Dental Needs

This study investigates whether workers with long working hours as well as shift workers perceive higher unmet dental care needs, and whether there is a gender difference in the associations. We used the Korea Health Panel (2009, 2011–2014) involving 20,451 person-wave observations from 5567 individuals. Perceived unmet dental care needs was defined when the participants reported that they perceived a need for dental treatment or check-up but had failed to receive dental care services during the past year. Fixed effects logit models were applied to examine how changes in weekly working hours or shift work status were linked to changes in perceived unmet dental needs within each individual. Among participants, 15.9–24.7% reported perceived unmet dental needs and the most common reason was time scarcity. We found that long working hours (>52 h/week) was significantly associated with perceived unmet dental needs due to time scarcity in both men (OR = 1.42, 95% CI 1.13–1.78) and women (OR = 1.35, 95% CI 1.03–1.79) compared workers working 40–52 h per week. Shift work was also a significant risk factor, but only in women (OR = 1.57, 95% CI 1.06–2.32). These findings provide evidence for labor policies to reduce working hours in order to improve access to dental care services.

Main Determinants

Particular working conditions and/or organization of working time may cause important sleep disturbances that have been proposed to be predictive of cognitive decline. In this regard, circadian rhythm misalignment induced by exposure to night work or long working hours would be responsible for cognitive impairment. Nevertheless, evidence supporting this correlation is limited and several issues still need to be elucidated. In this regard, we conducted a systematic review to evaluate the association between shift/night work and cognitive impairment and address its main determinants. Information provided by the reviewed studies suggested that night work might have serious immediate negative effects especially on cognitive domains related to attention, memory and response inhibition. Furthermore, cognitive performance would progressively worsen over consecutive night shifts or following exposure to very long work shifts. Otherwise, conflicting results emerged regarding the possible etiological role that night work chronic exposure would have on cognitive impairment. Therefore, circadian rhythm desynchronization, lack of sleep and fatigue resulting from night work may negatively impact worker’s cognitive efficiency. However, in light of the considerable methodological variability of the reviewed studies, we proposed to develop a standardized research and evaluation strategy in order to obtain a better and comprehensive understanding of this topic.

(1) Background: Near-miss incidents are the foundation of major injuries. They are warning signs that loss is imminent. Long working hours are a risk factor for near-misses along with sleep problems, job-related stress, and depressive symptoms. This study aimed to evaluate the indirect effects of long working hours via mediating variables on near-miss occurrences among Japanese healthcare professionals. (2) Methods: 1490 Japanese healthcare professionals’ reports from a web-based survey of workers in October 2018 were analyzed to evaluate total, direct, and indirect effects of long working hours on near-misses. We applied a generalized structural equation model with three mediating variables: sleep problems, job-related stress, and depressive symptoms. (3) Results: The total effect and direct effect of the categories of working hours longer than 41 h per week (h/w) for occurrence of near-misses were not significantly higher than that of 35–40 h/w. However, for indirect effects on occurrence of near-misses that first passed through job-related stress, there were higher reports for each category compared to 35–40 h/w, with odds ratios (OR) and 95% confidence intervals (95% CI) of OR = 1.12, 95% CI (1.07, 1.21) for 41–50 h/w; 1.25, (1.14, 1.41) for 51–60 h/w; and 1.31, (1.18, 1.51) for ≥ 61 h/w. (4) Conclusion: The results suggest that reducing working hours might improve job-related stress, which could reduce near-misses and prevent injuries.

Long Working Hours

ObjectivesAlthough the effects of long working hours on liver function remain unclear, in South Korea, there is a social perception that long working hours are associated with poor liver function. Thus, long working hours have recently become a major issue. This study aimed to determine the association between long working hours and liver function, as indicated by the alanine transaminase (ALT) levels.DesignCross-sectional study.SettingLarge university hospitals in Seoul and Suwon, South Korea.ParticipantsWorkers in formal employment who underwent a comprehensive health examination at the Kangbuk Samsung Hospital Total Healthcare Centre clinics in Seoul and Suwon, South Korea, between January 2011 and December 2018. Of the 386 488 participants, 212 421 met the inclusion criteria and were included in the analysis.Primary outcome measureALT elevation.ResultsThe participants were predominantly well-educated (86.1%), male (69.3%) and in their 30s (49.6%). In total, 13.4% of the participants presented ALT elevation (>40 IU/L). There was no significant association between working hours and ALT elevation in the general population and in the hepatitis B surface antigen (HBsAg)-negative group. Conversely, in the HBsAg-positive group, working >60 hours per week compared with 35–40 hours per week was significantly associated with ALT elevation. The association was more pronounced in those with ALT levels >80 IU/L (OR 1.94, 95% CI 1.24 to 3.01) than in those with ALT levels >40 IU/L (OR: 1.45, 95% CI 1.20 to 1.75). The p values for trend were <0.05.ConclusionsLong working hours were associated with ALT elevation only in hepatitis B virus carriers and not in the general population. Provided that there is adherence to the legal working hours, there is no need to further restrict working hours for liver health, irrespective of HBsAg status.
