Elimination Of Variables

This technical paper discusses a methodological and systematic way of resolving key challenges during introduction of Chip-On-Lead package specifically wirebonding issues that leads to production dilemma during production ramp-up of products using copper wire in tapeless leadframe. The project was intended to determine the “Red-X” or the major cause of yield detractors that may lead to quality issue during wirebonding process. Problem solving tools were showcased in this paper such as Data Analysis, Cause and Effect, Design-of–Experiment (DOE) and mechanical dimensional analysis which provided substantial impact in determining the real root-cause of the problem. Step-by-step elimination of variables was achieved with the use of statistical engineering tools. Outcome of the project eliminated the occurrence of Non-Stick-On-Pad (NSOP) during wirebonding process without cost involved and just optimizing the available in-house resources.  The improvements also enhanced the quality of the product after final test which on the other hand lower the risk of having potential customer complaint in the future.

Leaving Against Medical Advice

Background: A patient decides to leave the hospital against medical advice. Is this an erratic eccentric behavior of the patient, or a gap in the quality of care provided by the hospital? With a significant and increasing prevalence of up to 1–2% of all hospital admissions, leaving against medical advice affects both the patient and the healthcare provider. We hereby explore this persistent problem in the healthcare system. We searched Medline and PubMed within the last 10 years, using the keywords “discharge against medical advice,” “DAMA,” “leave against medical advice,” and “AMA.” We retrospectively reviewed 49 articles in our project. Ishikawa fishbone root cause analysis (RCA) was employed to explore reasons for leaving against medical advice (AMA). This report presents the results of the RCA and highlights the consequences of discharge against medical advice (DAMA). In addition, the article explores preventive strategies, as well as interventions to ameliorate leaving AMA.

Over Time

This brief report presents the global problem of the shortfall of donor corneal tissue for transplantation, a potential root cause (‘ick factor’ language), and a potential solution (modification of ‘ick factor’ language). Specifically, use of the term ‘eye donation’ is a potential hurdle to ocular tissue donation as it can stimulate the ‘ick factor.’ Verbiage such as ‘ocular (eye tissue)’ could be a method of providing terminology that is less emotive than ‘eye donor’ or ‘eye donation.’ The field of transplantation has experienced terminology shifts over time; for example, ‘cadaver’ has been replaced with ‘deceased donor,’ ‘harvest’ has been replaced with ‘recover,’ and ‘life support’ has been replaced with ‘ventilated.’ Notably, only a small number of regions worldwide are using ‘ocular’ terminology, yet it could be an important step to enhancing the informed consent process and improving donation rates, potentially increasing transplant and optimising patient quality of life for those with treatable blindness.

ABSTRACT Objective: to develop a mobile app for research on the use of tobacco among psychiatric patients and the general population. Method: applied research with the technological development of an app for data collection on an Android tablet. For its development, we considered three criteria: data security, benefits for participants and optimization of the time of researchers. We performed tests with twenty fictitious participants and a final test with six pilots. Results: the app collects data, stores them in the database of the tablet and export then to an Excel spreadsheet. Resources: calculator, stopwatch, offline operation, branching logic, field validation and automatic tabulation. Conclusion: the app prevents human error, increases the quality of the data by validating them during the interview, allows the performing of automatic tabulation and makes the interviews less tiring. Its success may encourage the use of this and other computational resources by nurses as a research tool.

Quality is one of the key success factors to achieve competitive advantage. When companies succeeded to improve quality of the service or product given, they will have the possibility to increase their market share and eventually their profit. One of the methods to increase quality is by doing six sigma analysis that focuses on the cause of the problem. The research is done in PT Cemara Agung, one of textile industries in Indonesia. Research method used is descriptive study. Literature study, observations, and interviews has been done in order to search root cause and generate recommendations. The analysis shows that almost fifty percent of the main cause in defect products is happened to the weaving department, which then cause the profit of the company decreased as an impact of the spoilage produced. By doing six sigma analysis and finding recommendations to resolve the problems, the company is expected to be able to reduce the quality cost, increase the quality and eventually increase the profit of the company.

Visible Volume

Visual pollution (VP) is a visual landscape quality issue, and its most consistently recognized symptom is an excess of out of home advertising billboards (OOHb). However, the VP related research concerns landscape aesthetic and advertisement cultural context, leaving the impact of outdoor billboard infrastructure on landscape openness unanswered to date. This research aims to assess the visual impact of outdoor billboard infrastructure on landscape openness, precisely the visual volume—a key geometrical quality of a landscape. The method uses 3D isovists and voxels to calculate the visible and obstructed subsets of visible volume. Using two case studies (Lublin City, Poland) and 26 measurement points, it was found that OOHb decreased landscape openness by at least 4% of visible volume; however, the severe impact may concern up to 35% of visual volume. GIS scientists develop the proposed method for policy-makers, and urban planners end users. It is also the very first example of compiling 3D isovists and voxels in ArcGIS Pro software in an easy-to-replicate framework. The research results, accompanied by statistically significant proofs, explain the visual landscape’s fragility and contribute to understanding the VP phenomenon.

The customer complaint is considered an expression of dissatisfaction against the quality of the product or information associated with them. An effective mechanism for product complaint handling is one of the essential business requirements of the pharmaceutical industry. The customer complaints have the potential to jeopardize the firm's reputation and trigger regulatory action. This study shows that the prevailing complaint handling practices in the pharmaceutical sector follow a random and independent approach without synchronizing the strategy with the gross interest of stakeholders. The study explores the dearth of study for overall mitigation of adverse impacts on business due to patient's risk, impending legal and regulatory actions. The existing system to handle pharmaceutical complaints is handled with a technical perspective, without effective involvement of the distribution personnel. This study has produced a unique pathway to redress pharmaceutical product complaints effectively.

Aims: To determine the prevalence of urinary incontinence, risk factors and impact on the quality of life in gynecological clinic attendees of a University Hospital. Methods: A cross sectional descriptive study was conducted amongst gynecological clinic attendees in a Teaching Hospital in Nigeria from 1st February to 31st July 2017. Structured questionnaires were used to ascertain the presence of urinary incontinence. Socio-demographic and medical factors; impact on daily activities and treatment history were assessed. Women with and without urinary incontinence were compared. Univariate, bivariate and multivariable analyses were performed. Results: There were 395 women of 25 - 67 years (mean age = 38.81±10.1). About 33% had experienced urinary incontinence in the previous 6 months with Urgency, Mixed and Stress urinary incontinence occurring in 18.0%, 7.6% and 7.3% respectively. Independent risk factors for urinary incontinence were age (odds ratio=0.49, 95% confidence interval [CI] =0.26 - 0.92, P =0.026), higher body mass index (odds ratio=1.92, 95% CI =1.53 - 3.00, P =0.004) and history of constipation (odds ratio=2.11, 95% CI =1.30 - 3.43, P =0.003). About 47% of those with urinary incontinence admitted to negative feelings like anxiety and depression; 45% had moderate to severe impact on their quality of life in all domains but only 27.7% sought help. Conclusions: Urinary incontinence is common and risk factors include older age, high body mass index and constipation. Despite its substantial impact on the quality of life, majority do not seek help. Addressing modifiable risks factors and improving treatment seeking behaviour will assist in reducing the prevalence of urinary incontinence. Keywords: female urinary incontinence; quality of life; risk factors; stress incontinence; urgency incontinence.

Purpose There is no particularly efficient way to measure research output, but effectual assessment of research output is necessary to motivate and encourage researchers to enhance their research performance and disseminate knowledge. The purpose of this paper is to highlight the exacerbating pressure on Indian academics to deliver incessantly in terms of research output and identify an agreeable way to increase research output. The metric explores trends in management publications by Indian academics and presents an overview of collaborative practices by Indian management researchers that could shine a light on the trends of collaborative publishing future. Design/methodology/approach The study focuses on publications in the area of Business and Management. Scopus was used with advanced filters to draw relevant research papers. Data were then sorted and filtered on the basis of quality determined through Australian Business Deans Council rankings and diverse bibliometric information to understand the pattern of research output of Indian academics. Findings The research found that the rate of collaboration with researchers from the home country is low for top rated publications. Majority of publications were listed in Scopus indexed journals, whereas a handful featured in A and A* journals. A and A* journals were predominantly co-authored with academics from universities outside the country. Tradeoff was achieved by majority of authors by getting published in B, followed by C category journals to achieve research outputs. Research limitations/implications The study is limited to publications in the area of Business and Management and may be extended to other disciplines such as economics, engineering, law, medical sciences, etc., to understand publishing trends at universities in the country. The study can also be conducted in understanding a similar dilemma with academics at other countries that are evolving in research culture. Practical implications The study would help management researchers to dig deep into the root cause and understand why and how collaborations within and outside the country impact the quality of publications. The results would further encourage ranking agencies to award suitable grades to colleges that promote collaboration within the country as well as international collaboration. The study also conducts a benchmarking exercise of the institutions in the country that would be useful for researchers, journals and colleges. Originality/value While earlier studies have highlighted the importance of foreign collaborations in academic publishing, there are a handful of studies that have focused on the role of collaboration within the home country. The practice of Indian authors collaborating with Indian counterparts at other universities would help understand the expertise of researchers at different universities and encourage the collaboration process and quality of publications in the country.
