The work system method was developed iteratively with the overarching goal of helping business professionals understand IT-reliant systems in organizations. It uses general systems concepts selectively, and sometimes implicitly. For example, a work system has a boundary, but its inputs are treated implicitly rather than explicitly. This chapter asks whether the further development of the work system method might benefit from integrating general systems concepts more completely. After summarizing aspects of the work system method, it dissects some of the underlying ideas and questions how thoroughly even basic systems concepts are applied. It also asks whether and how additional systems concepts might be incorporated beneficially. The inquiry about how to use additional system ideas is of potential interest to people who study systems in general and information systems in particular because it deals with bridging the gap between highly abstract concepts and practical applications.

This article describes proposed content of an online toolkit for users of the work system modeling method (WSMM), an extension of the work system method (WSM), which was developed to help business professionals understand IT-reliant systems and collaborate with IT professionals. A summary of work system theory (WST) and WSM provides a background. A two-dimensional design space for modeling methods illustrates WSMM's context. Two limitations of WSMM imply the need for a toolkit that overcomes those limitations. An auto rental example is used to illustrate a series of modeling, analysis, and design modules related to different stakeholder purposes. Most of the modules reflect components of Word documents used as outlines to produce over 700 management briefings, mostly by MBA and Executive MBA students, between 2003 and 2017. A concluding section summarizes the main ideas, explains how the use of different modules based on the work system metaphor flexibly supports systems analysis and design, and identifies challenges for future research.

Dari  hasil penelitian ini sistem informasi ERP sudah berjalan dengan baik tetapi pihak perusahaan tetap perlu melakakukan perbaikan-perbaikan untuk memberikan kepuasan dalam penggunaan sistem inforamasi tersebut. Kata Kunci : Evaluasi kinerja, Sistem Informasi ERP, Metode Pieces Framework AbstractThe use of information systems at this time has been widely used by companies, one of them is PT, HK Realtindo Jakarta. Implementation of information systems used by some parts of one part of financial accounting and sales marketing. Research using Pieces Framework method by measuring six variables such as performance, Information / data, Economic, Control, Efficiency, and service. This method is used to measure the level of acceptance of information system applications that have been applied to the user. The use of this information system has long been used so that the necessary research on the system, in this study there are 30 questionnaires are processed and consists of 20 indicators of questions. In this research yield data of all good variable with total performance appraisal 3,81, Information / data equal to 4,11, Economic mengahsilkan value 4,07, securty/control get point value 4,13, Efficiency with data value 4,13, and service get value 4.06 From the results of this research ERP information system is running well but the company still need melakakukan improvements to provide satisfaction in the use of the system informationt Keywords: Performance Evaluation, ERP Information System, Method Pieces Framework

Purpose Considering current development of Grey Systems Theory (GST), we can come up with the following thesis: practical applications are a dominant subject of research. Thus, what seems to be symptomatic for relatively young knowledge disciplines, the authors observe the presence of imbalance between the development of GST application tools and theory’s epistemological and methodological background. As for GST, epistemological and methodological problems are becoming visible especially in the issues of determining a clear criterion of demarcation of this kind of a theory from others. In other words, this problem can be reduced to the issue of a precise determination of what the category of a grey system and grey information is. This problem is of great importance for further development and popularisation of GST in the world of science. Realising its significance, the purpose of this paper is to create a general overview of Grey Systems epistemology and afterwards create axiomatic and formal frames for a category of greyness. Design/methodology/approach In order to achieve set goals, two research approaches were accepted. In the area of inference about epistemology of GST an approach characteristic of an analytical philosophy was used, whereas in the case of axiomatic and formal frames for a category of greyness the authors referred to terms of a set theory and the principles of a pragmatic logic. Findings The result of research is to formulate a concept of a grey system and a concept of grey information in the context of a process of cognition. Moreover, a function of greyness and other fundamental categories of GST will be defined in an axiomatic way. Originality/value The paper presents a new consistent frame for the issues of methodological and epistemological backgrounds of GST. An original concept is to refer in considerations to a newly proposed grey space. This space was used for a formal justification of such elementary categories as grey numbers, a weight function of whitenization or grey sequences. The value of achievements shown in the paper is underlined by the fact that proposed theoretical constructions require further development and they can potentially open up new research trends in the GST.

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] There are two experimental chapters in this dissertation in which the fundamental questions center around aptamers and viruses and how these two concepts interlace. The first experimental chapter (chapter two) seeks to utilize previously characterized aptamers against HIV-1 Reverse Transcriptase (RT) that will be delivered by a lentiviral vector and which intracellular expression from different human promoters was evaluated. The goal of this study was to identify important elements of vector design that will impact transgene expression in target cells. This study was based on the hypothesis that intracellular expression of RNA aptamers delivered by a lentiviral vector could offer a platform to enable adequate aptamer expression that would translate into viral suppression. And the second experimental chapter (chapter four) describes an in vitro 2'FY-RNA selection against Filoviral glycoproteins and outlines three different strategies that were followed to achieve selection of specific aptamers. Aptamers described in this chapter were able to recognize Ebolavirus glycoprotein ectodomain as well as in its native conformation displayed on the viral surface. Taking the observations obtained in this dissertation, aptamer technology could be expanded into further development for practical applications.

This chapter studies the requirements for a wide range of healthcare information systems, including, but not limited to, clinical pathways management, patient record management, home care management, and medical personnel and resource management. The analysis concentrates on the description and management of medical activities, leaving aside the standard management processes common to all enterprises. It develops a generic architecture for these information systems comprising four central submodels devoted to the description, respectively, of organizational structures, care processes, information, and resources. Each submodel is analysed independently of the others then integrated into a consistent global model. Extensions of this model to other facets of the healthcare information system are discussed and some practical applications are suggested.

Work System

With increased use of telehealth to provide healthcare services, bringing telehealth technology out of experimental settings into real life settings, it is imperative to gain a deeper understanding of mechanisms underlying the assimilation of teleheath systems. Yet, there is little understanding of how information systems are assimilated by organizations, more work is then warranted to understand how telehealth can be integrated into administrative and clinical practices and to identify factors that may impinge onto telehealth integration. Borrowing from institutional, structural and organizational learning theories, the authors develop a multilevel model for understanding assimilation of telehealth systems. Their study addresses limitations of past work and will be helpful for guiding research and managerial actions while integrating telehealth in the workplace.
