The external and data loose coupling for the integration of software units: a systematic mapping study

Integration of legacy and third-party software systems is almost mandatory for enterprises. This fact is based mainly on exchanging information with other entities (banks, suppliers, customers, partners, etc.). That is why it is necessary to guarantee the integrity of the data and keep these integration’s up-to-date due to the different global business changes is facing today to reduce the risk in transactions and avoid losing information. This article presents a Systematic Mapping Study (SMS) about integrating software units at the component level. Systematic mapping is a methodology that has been widely used in medical research and has recently begun to be used in Software Engineering to classify and structure the research results that have been published to know the advances in a topic and identify research gaps. This work aims to organize the existing evidence in the current scientific literature on integrating software units for external and data loose coupling. This information can establish lines of research and work that must be addressed to improve the integration of low-level systems.

First-Level Systematic Echocardiographic Evaluation in a COVID-19 Lombardy Hospital

Coronavirus Disease 2019 (COVID-19) is a global pandemic. Although cardiovascular (CV) morbidity has been associated to the clinical course of the disease, systematic data regarding CV implications during COVID19 are still lacking. The aim of this study is to report the echocardiographic features of COVID19 patients undergoing first-level echocardiographic screening in a COVID Hospital in Lombardy. In this retrospective study, 70 consecutive patients admitted to our Hospital with confirmed COVID-19 diagnosis, underwent a first-level echocardiographic screening. Of the 70 patients, 8 (11.4%) patients died; survivors had lower sPAP levels as compared to deceased subjects (25.4±9.4 vs 34.8±5.9 mmHg, p=0.008) and splitting the patients in four quartiles based on sPAP, mortality rate was significantly higher among patients with more elevated sPAP compared to the other groups (Q4 29.4% vs Q3 12.5% vs Q2 6.25% vs Q1 0%, p=0.026). A first-level echocardiographic screening might be helpful in the management of Covid-19 patients by identifying those at higher risk of fatal outcome.

Students’ experiences with different learning pathways to higher professional bachelor programmes

Context: In the Dutch educational system, different learning pathways to higher professional bachelor (or HBO) programmes have been created: the regular VET route, the general secondary education route, and continuing learning pathways (such as the Green Lyceum or GL) that combine characteristics of these two traditional routes and that are specifically designed for students who combine a relatively high cognitive level with an affinity for practical, vocation-oriented assignments. Approach: The present study aimed to compare the experiences of students coming from these three different learning pathways to HBO. 62 former GL students, 127 former middle-management VET (or MBO) students, and 81 former regular general secondary education (or HAVO) students completed an online questionnaire on their experiences in their first HBO study year and their scores on the various scales were compared. Findings: Students from the three groups were equally satisfied with their current HBO programme. The same pattern was found for perceived study success in their HBO programme. Former GL students, however, mentioned that they had been better prepared in terms of development of study skills needed in HBO. Compared with the MBO route to HBO, former GL students felt better prepared in terms of the theoretical subjects addressed in their previous educational programme. In this regard, their level of theoretical preparation was comparable to that of former HAVO students. When the vocation-oriented aspects of education were concerned, however, the GL appeared to be comparable with the MBO route to HBO (in the HAVO curriculum, vocation-oriented preparation for HBO is absent). Moreover, former HAVO students scored lower than former GL and former MBO students with respect to the extent to which they felt that they had received support in choosing a particular HBO programme in their previous educational programme.Conclusion: The GL seems to combine the advantages of MBO and HAVO programmes for this particular group of students: theoretical preparation for HBO at HAVO level combined with practical preparation at MBO level, systematic career orientation and guidance, and development of study skills required in HBO. In other words, such continuing learning pathways can be a curriculum design solution for specific student groups to promote their transition to HBO.
