Gathering Data

Unified Modeling Language (UML) is accepted as the standard for modeling software designs and is commonly used in software development Thus this paper investigated the practice of Junior and Senior Business System Developers in the use of UML and other Diagrams. Part of the study is the UML Systems modeling usage for Junior Developers by investigating the documentation used in development. This study used several methods in gathering data, interview, and questionnaire from junior and senior developers was used to come up with a result. It also investigates the possible usage of UML Diagrams in Business field which will be a basis for a future proposed content curriculum for both Business Administration and Information Technology. The result of the study shows that junior developers are not using UML Systems modeling, while senior developers increase as the experience increase in development. Most of the respondents used a diagram that is outside in the UML family. The study also shows that UML helps the managers and business people to build models and diagram that helps them to put things into perspective. It proposed that UML Diagrams should include in business Subject for both programs, the business and information technology program should unite to increase the UML usage.

Mechanical Strengths

Biodegradable polymer microneedle (MN) arrays are an emerging class of transdermal drug delivery devices that promise a painless and sanitary alternative to syringes; however, prototyping bespoke needle architectures is expensive and requires production of new master templates. Here, we present a new microfabrication technique for MNs using fused deposition modeling (FDM) 3D printing using polylactic acid, an FDA approved, renewable, biodegradable, thermoplastic material. We show how this natural degradability can be exploited to overcome a key challenge of FDM 3D printing, in particular the low resolution of these printers. We improved the feature size of the printed parts significantly by developing a post fabrication chemical etching protocol, which allowed us to access tip sizes as small as 1 μm. With 3D modeling software, various MN shapes were designed and printed rapidly with custom needle density, length, and shape. Scanning electron microscopy confirmed that our method resulted in needle tip sizes in the range of 1 – 55 µm, which could successfully penetrate and break off into porcine skin. We have also shown that these MNs have comparable mechanical strengths to currently fabricated MNs and we further demonstrated how the swellability of PLA can be exploited to load small molecule drugs and how its degradability in skin can release those small molecules over time.
