Dmaic Method

Product quality has now become one of the main factors that every company must have to compete globally. One way is to reduce the number of defective products in the production process. This method is a continuous improvement effort made by PT Toyota Motor Manu­fac­turing Indonesia and companies engaged in the automotive sector that produces cars. One of the processes is packing roof panels whose output will be sent to importing countries where the number of re­quests per month is relatively high but still has a high defect rate. Based on production data and defect data for the January-February 2019 period, roof panel packaging production has a 1% -3% defect rate. This company must reduce the defect rate to achieve the com­pany target of zero defects. This study aims to improve the quality of the packaging process by minimizing the number of defective products. This study uses the Six Sigma method with DMAIC phases. This method has several phases, namely, Define, Measure, Analysis, Improvement, and Control. Corrective action to reduce product defects based on 5W + 1H is to formulate a repair plan at the upgrade phase, namely by making SOPs spraying anti-rust and supervising operators who produce roof panel packaging. The improvement results reduced the DPMO value from 33,500 units to 2,050 units and increased the sigma level from 3.33 to 4.37. The DMAIC phase effectively controls and improves product quality levels in the automotive industry.

AbstractOlder people today are more likely to age in their own private living environment. However, many face declining health and/or other issues that affect their ability to live independently and necessitate additional support. Such support can be provided by formal networks, but a considerable part can also be offered by informal networks of older people themselves. Going beyond these networks, older people can additionally and perhaps even more substantially benefit from vital communities. Nevertheless, even though this term is increasingly common in the literature, its meaning remains indistinct. A more thorough understanding of this concept might provide valuable knowledge that health care professionals, researchers and community workers can use to offer meaningful and effective support. The purpose of this paper is to draw on existing empirical research on vital communities to build knowledge of the different descriptions and dimensions of the concept. Arksey and O’Malley’s scoping review methodology was adopted. Our search, conducted on 23 March 2020 and updated on 06 January 2021, yielded 4433 articles, of which six articles were included in the scoping review. We deduced that the conceptualisation of a vital community is based on three dimensions: the aim of a vital community, the processes behind a vital community and the typical characteristics of a vital community. None of the selected studies have mapped all three dimensions. Nevertheless, we assume that understanding all three matters when vital communities aim to contribute to the quality of life of people ageing in place.

The growing industrial world will result in a lot of competition. Companies that can compete are companies that can maintain the quality of their products well so that they can meet customer satisfaction. Therefore, quality control is needed. This research is focused on reducing defects in red brick products at CV. Ghatan Fatahillah with the Six Sigma-DMAIC method (Define, Measure, Analyze, Improve, and Control). From the research results obtained DPMO of 36,212 with a sigma value of 3.29. The type of defect that most often occurs in red bricks is broken / broken, which is 4,327 or 59.81% of the total defective products. The results of the Analyze stage with the fishbone diagram showed that the causes of breakage / defects were determined, namely: workers do not understand quality standards, lack of product inspection, workers do not understand work procedures, unstable machine performance, workers are not careful, the number of mills is erratic, and composition erratic bricks. So it is necessary to make improvement proposals in order to reduce the number of defective products in red bricks. Keywords: DMAIC, DPMO, Quality Control, Six Sigma

The aim of this experimental study was to evaluate the sedative and cardiorespiratory effects of alfaxalone and midazolam after intramuscular administration in pigs. Fourteen pigs, weighing 18 to 22 kg, aged between 55 and 70 days, American Society of Anaesthesiologists classification 2, affected by congenital reducible umbilical hernia, were included in the study. Alfaxalone (5 mg/kg) and midazolam (0.5 mg/kg) mixed in the same syringe were administered into the neck muscle. Pain on injection, quality of sedation and time to achieve lateral recumbency were recorded. Heart rate (HR), respiratory frequency (fR), and rectal temperature (RT) were recorded at 0 (baseline: before drug administration), 10, 15, and 20 min after the injection. Oxygen saturation of haemoglobin (SpO2), arterial blood pH, arterial oxygen (PaO2) and carbon dioxide (PaCO2) tensions and bicarbonate concentration (HCO3-) were recorded at 10, 15, and 20 min after injection. Continuous data were analysed using a repeated-measure analysis of variance (ANOVA) and a P-value < 0.05 was considered significant. Ten animals out of fourteen showed no pain on injection, whereas the remaining four exhibited mild pain. The time from the end of injection to lateral recumbency was 266 ± 40 s. The quality of sedation ranged between good to very good. No significant changes in the variables monitored were observed between the time points. In conclusion, the intramuscular administration of alfaxalone and midazolam in pigs at the doses used induced reliable and fast sedation, without pain on injection and moderate respiratory effects.

The authors analyze an extensive set of data for measuring the daily surface profi le of the cultivated soil to assess its agrotechnical parameters. The research was carried out on a small agricultural catchment area of the Orininsky rural settlement, which is located in the Morgaushy district of the Chuvash Republic. Three agricultural fi elds were selected, ranging from 25 ha to 53 ha. The studied areas were cultivated in various ways: plowing with harrowing, disking the soil and winter plowing. The profi les of the studied elementary sections were measured using a developed ground-based circular laser profi lometer. Data on the state of the profi le were used to determine the main agrotechnical parameters - clumping, cloddiness, surface slope, and deviation of the travel trajectory of a machine and tractor unit from the line of equal height. A software tool for processing and analyzing data received from sensors has been developed. The results established that the deviation of the projection of the greatest elevation line changes (measured by the slope) from the travel trajectory of a unit with an angle of 62, a slope of 6.5, and in a quantitative size distribution soil aggregates of 1…4 inches in diameter prevail. The weighted average diameter of the clods was 3.99 cm. The research results have determined the use of recommend methods for stating the agrotechnical parameters of the daylight surface to evaluate the cultivated soil in accordance with agrotechnical requirements.

Abstract Background There is a high global burden of neonatal mortality, with many newborn babies dying of preventable and treatable conditions, particularly in low and middle-income countries. Improving quality of newborn care could save the lives of many thousands of babies. Quality of care (QoC) is a complex and multifaceted construct that is difficult to measure, but patients’ experiences of care are an important component in any measurement of QoC. We report the findings of a qualitative study exploring observations and experiences of health workers (HWs) and mothers of babies in neonatal units in South Africa. Methods A qualitative case study approach was adopted to explore care of newborn babies admitted to neonatal units in district hospitals. Observation data were collected by a registered nurse during working hours over a continuous five-day period. Doctors and nurses working in the neonatal unit and mothers of babies admitted during the observation period were interviewed using a semi-structured interview guide. All interviews were audio recorded. Observation data were transcribed from hand written notes. Audiotapes of interviews were transcribed verbatim and, where necessary, translated into English. A thematic content analysis was used to analyse the data. Results Observations and interviews were conducted in seven participating hospitals between November 2015 and May 2016. Our findings highlight the importance of information sharing between HWs and mothers of babies, contrasting the positive communication reported by many mothers which led to them feeling empowered and participating actively in the care of their babies, with incidents of poor communication. Poor communication, rudeness and disrespectful behaviour of HWs was frequently described by mothers, and led to mothers feeling anxious, unwilling to ask questions and excluded from their baby’s care. In some cases poor communication and misunderstandings led to serious mismanagement of babies with HWs delaying or withholding care, or to mothers putting their babies at risk by not following instructions. Conclusion Good communication between mothers and HWs is critical for building mothers’ confidence, promoting bonding and participation of mothers in the care of their baby and may have long term benefits for the health and well-being of the mother and her baby.

NICE (National Institute for Health & Care Excellence) guidance recommends that healthcare professionals with expertise in palliative care should be an integral part of the multidisciplinary team in managing patients with motor neuron disease (MND). Those in the poorest prognostic group may benefit from early referral to help manage rapidly progressive symptoms, psychological distress and offer additional support with complex decision-making and early robust advance care planning. Patients frequently develop dysphagia and gastrostomy feeding can be used to prolong survival and improve quality of life. As the disease progresses patients may request withdrawal of life-sustaining treatment such as gastrostomy feeding; however, a literature search found no evidence or guidance on how best to facilitate this. We present the case of a patient with MND admitted to the hospice inpatient unit requesting withdrawal of gastrostomy feeding, outline the challenges and need for further consensus guidelines to inform practice.

Abstract Background Idiopathic epilepsy is a common neurological condition in dogs. Previous research has focused on clinical aspects of seizure management in dogs with idiopathic epilepsy with little attention given to the emotional and logistical challenges for their owners. The current study aimed to explore the impacts of owning a dog with idiopathic epilepsy on owner quality of life and lifestyle, using qualitative methods. Methods Owners of dogs with idiopathic epilepsy living in England were recruited via social media and word of mouth, and then selected using purposive sampling to participate in face-to-face semi-structured interviews. Epilepsy management was explored through in-depth accounts of owner experiences and influencing factors. Interviews were recorded and transcribed verbatim and thematic analysis was used to construct key themes. Results Twenty-one interviews were completed. Almost all owners had made lifestyle changes in order to care for their dog, including substantial modifications to routines and, in some cases, employment. Many owners discussed a very emotionally close dog-owner bond, and described experiencing frequent feelings of fear, stress and uncertainty regarding their dog’s health. Friends, family and colleagues did not always understand the magnitude of commitment required to care for a dog with idiopathic epilepsy. This, combined with a fear of leaving their dog unsupervised, had social implications in some instances and lead to increased use of the Internet and online groups for peer support. Conclusions The commitment required to care for a dog with idiopathic epilepsy, and the lifestyle changes made by their owners, may be far greater than previously estimated. Further consideration of these factors by veterinary professionals and the friends and families of owners of dogs with idiopathic epilepsy could improve owner quality of life, and facilitate the provision of additional support.
