Metabolic Syndrome, Homocysteine and uric acid in patients with obesity; experience from obesity and work centre

BACKGROUND: Uric acid (UA) and homocysteine (HCys) are involved in cardiovascular diseases. Patients with obesity (PwO) are characterized by elevated cardiovascular risk. OBJECTIVE: To evaluate the relationship between HCys and UA concentrations in 1141 overweight patients and PwO with and without metabolic syndrome (MS). METHODS: MS was defined according to IDF criteria (2005). Anthropometric data were recorded and blood biochemical parameters were assessed with routine methods on fasting blood samples. Statistics: Spearman correlation and multiple regression analysis. RESULTS: Gender, obesity and MS influenced both UA and HCys levels, which were increased in males, MS patients, PwO with MS and positively correlated (p < 0.001). Patients without MS had normal or slightly high levels. Hypertension, hyperuricemia and hyperhomocysteinemia were found in PwO with MS. UA concentration correlated with systolic blood pressure, triglycerides and HDL (all p < 0.05). Multivariate analysis showed that HCys concentration was an independent determinant factor affecting UA levels (T value 3.5, p < 0.001). CONCLUSIONS: HCys and UA levels positively and significantly correlated in PwO, especially in those with MS. The significant correlation between UA and hypertension, triglycerides, HDL suggests the clinical usefulness of monitoring UA together with HCys concentrations as cardiovascular risk marker in these patients.

Business Is Changing: Expert and Public Opinion on the Future of Work and Artificial Intelligence Through Social Media Research

Big name organizations have proposed that AI will fundamentally transform the future of business by altering the skills that will be required to stay competitive in an epoch where routine- jobs are automated and where workers in less-routine jobs are displaced from burgeoning advancements in AI. When it comes to assessing the impact of hazardous technologies, a growing body of literature suggests that experts and everyday people tend to perceive risks differently. Social media is a tool that allows individuals to engage with one another, and more recently, social media has become an influential means of consuming and disseminating news online. Reddit is a form of social media that combines both news consumption and social engagement. This major research project (MRP) examines online discourses from end-users on Reddit, from articles written by journalists, and from experts quoted in the media. Inductive content analysis reveals that topics of conversation about AI and the future of work centre around inequality and the economy. Apparent differences are observed between end-users, journalists, and experts, such as the high prevalence of dread on Reddit, which may suggest that most individuals, as opposed to those in the news media, think negatively about AI being introduced into the workplace—for reasons that revolve around the economy, inequality, or both.

ANALISIS KEBUTUHAN KAPASITAS PRODUKSI DENGAN MENGGUNAKAN METODE ROUGH CUT CAPACITY PLANNING DI PT WIJAYA KARYA BETON

PT. Wijaya Karya Beton merupakan salah satu perusahaan yang bergerak dalam industri pembuatan tiang beton yang berlokasi di jalan Medan – Binjai Km 15,5 Desa Sei Semayang Kecamatan Sunggal, Kabupaten Deli Serdang. Perusahaan ini berproduksi bersadasarkan pesanan (make to order). Dimana permintaan yang tinggi akan menjadi keuntungan bagi perusahaan tetapi akan menjadi kerugian bagi perusahaan apabila tidak dapat memenuhi pesanan tepat waktu. Berdasarkan data masa lalu PT. Wijaya Karya Beton mengalami permintaan yang berfluktuatif dari bulan Januari- Desember 2019 namun tidak mempertimbangkan sumberdaya kapasitas produksi yang tersedia sehingga terjadi keterlambatan dalam menyelesaikan produk. Penelitian ini bertujuan untuk mengetahui kebutuhan kapasitas produksi dengan metode rough cut capacity planning serta menggunakan perhitungan peramalan sebagai acuan permintaan konsumen dimasa yang akan datang. Berdasarkan hasil laporan RCCP kekurangan kapasitas terjadi pada work centre III, V, VI, VII. Pada work centre III kekurangan kapasitas sebesar 114 jam dan pada work centre V kekurangan kapasitas sebesar 116 jam, langkah yang dilakukan untuk mengatasi kekurangan kapasitas dengan melakukan penyesuaian (readjustment) kapasitas dengan memindahkan beban kerja ke periode yang mengalami kelebihan kapasitas. Pada work centre VI kekurangan kapasitas sebesar 29140 jam dan pada work centre VII kekurangan kapasitas sebesar 2435 jam, langkah yang dilakukan untuk mengatasi kekurangan kapasitas dengan menambahkan jam kerja lembur disetiap bulannya. Setelah dilakukan penyesuain (readjustment) dan penambahan jam kerja lembur maka kapasitas untuk setiap work centre dapat terpenuhi.

Multisectoral cooperation in cases of domestic violence from the point of view of the social work centre

The aim of this research was to determine the current state of multisectoral cooperation between the competent state bodies and institutions provided by the Law on Prevention of Domestic Violence, recognized as a basis for preventing domestic violence and providing protection and support to victims. The empirical findings were obtained by surveying 43 employees in the social work centres in the Srem administrative district, who act in cases of domestic violence. After data collection, they had to be organized, so the statistical method of descriptive statistics was applied and for that purpose, the statistical software package SPSS was used (ver. 20). The results of the research showed the efficiency of mutual cooperation between the competent authorities, but also the necessity of continuing the work on the reform of the above-mentioned legal text.

Migrants and the Global City

This chapter considers three unique aspects in London's migratory history through a series of other interlinked features: demography, globality, employability, social mobility, and a revisiting of diversity. These five headings can provide a deeper understanding of the relationship between migration, globality, and diversity. This is especially seen through the prism of employment because the discussions have demonstrated that, while London has for most of the last three centuries constituted the political and financial capital of the world, this has fed into its importance as a global work centre. It has attracted people from Britain, Europe, and the rest of the world seeking employment in all sectors of the economy. This includes cleaners as well as hawkers, musicians, footballers, and political and financial elites.

The social work Reconceptualisation Movement in Latin America and the renewal in Brazil: the protagonist role of the Latin American Social Work Centre

This article is part of the research ‘The Social Work Reconceptualization Movement in Latin America: Historical Determinants, International Interlocutions and Memory’. It portrays the 1960s’ socio-political framework in Latin America, as well as the cultural, ideo-political and socio-economic processes that have deeply affected global societies. In this context, it situates the contribution of the Latin American Social Work Centre to the Reconceptualisation Movement of social work in Latin America, when breaking with traditional social work, and the so-called ‘turnaround’ of Brazilian social work, responsible for profound transformations in academic and professional development and education, professional activity, and organisation, through the political articulation of several professional entities.

Production Planning and Control as Routing in Manufacturing Networks

In this paper, we explore the use of network routing for production planning and control in manufacturing of complex industrial products. Such a product is the result of a joint effort of many manufacturing companies; each considered a collection of work centre nodes connected by transportation links forming a company-wide manufacturing network. Each company is, in turn considered a manufacturing node connected to other manufacturers by transportation links forming a distributed manufacturing network that produces the final product. We model the manufacturing network as a distribution network where the incoming and outgoing inventories of products are distinct nodes in addition to the work centre nodes. Production planning and control are done by minimizing the cost of handling all products in all work centre nodes. This formulation provides a scalable and flexible production planning and control scheme adhering to the networked structure of manufacturing of complex products. We apply the model to a company-wide manufacturing network as a first approach. A case study using the model demonstrates production planning using network routing at a manufacturer of ship propulsion engines.
