Software Process Modeling with Eclipse Process Framework

The software development industry is constantly evolving. The rise of the agile methodologies in the late 1990s, and new development tools and technologies require growing attention for everybody working within this industry. The organizations have, however, had a mixture of various processes and different process languages since a standard software development process language has not been available. A promising process meta-model called Software & Systems Process Engineering Meta- Model (SPEM) 2.0 has been released recently. This is applied by tools such as Eclipse Process Framework Composer, which is designed for implementing and maintaining processes and method content. Its aim is to support a broad variety of project types and development styles. This thesis presents the concepts of software processes, models, traditional and agile approaches, method engineering, and software process improvement. Some of the most well-known methodologies (RUP, OpenUP, OpenMethod, XP and Scrum) are also introduced with a comparison provided between them. The main focus is on the Eclipse Process Framework and SPEM 2.0, their capabilities, usage and modeling. As a proof of concept, I present a case study of modeling OpenMethod with EPF Composer and SPEM 2.0. The results show that the new meta-model and tool have made it possible to easily manage method content, publish versions with customized content, and connect project tools (such as MS Project) with the process content. The software process modeling also acts as a process improvement activity.

Telementoring during endovascular treatment of abdominal aortic aneurysms: a prospective study.

PURPOSE: To explore the use of telementoring for distant teaching and training in endovascular aortic aneurysm repair (EVAR). METHODS: According to a prospectively designed study protocol, 48 patients underwent EVAR: the first 12 patients (group A) were treated at a secondary care center by an experienced interventionist, who was training the local team; a further 12 patients (group B) were operated by the local team at their secondary center with telementoring by the experienced operator from an adjacent suite; and the last 24 patients (group C) were operated by the local team with remote telementoring support from the experienced interventionist at a tertiary care center. Telementoring was performed using 3 video sources; images were transmitted using 4 ISDN lines. EVAR was performed using intravascular ultrasound and simultaneous fluoroscopy to obtain road mapping of the abdominal aorta and its branches, as well as for identifying the origins of the renal arteries, assessing the aortic neck, and monitoring the attachment of the stent-graft proximally and distally. RESULTS: Average duration of telementoring was 2.1 hours during the first 12 patients (group B) and 1.2 hours for the remaining 24 patients (group C). There was no difference in procedural duration (127+/-59 minutes in group A, 120+/-4 minutes in group B, and 119+/-39 minutes in group C; p=0.94) or the mean time spent in the ICU (26+/-15 hours in group A, 22+/-2 hours in group B, and 22+/-11 hours for group C; p=0.95). The length of hospital stay (11+/-4 days in group A, 9+/-4 days in group B, and 7+/-1 days in group C; p=0.002) was significantly different only for group C versus A (p=0.002). Only 1 (8.3%) patient (in group A: EVAR performed by the experienced operator) required conversion to open surgery because of iliac artery rupture. This was the only conversion (and the only death) in the entire study group (1/12 in group A versus 0/36 in groups B + C, p=0.31). CONCLUSIONS: Telementoring for EVAR is feasible and shows promising results. It may serve as a model for development of similar projects for teaching other invasive procedures in cardiovascular medicine.

Puurakenteisten hallien elementti- ja runkoasennustoiminnan kehittäminen

Työn tarkoituksena oli kehittää puurakenteisten elementtihallien asennustoimintaa. Tämä tehtiin selvittämällä nykyisestä toiminnasta yleisimpiä ongelmakohtia ja niiden syitä. Teoriaosuudessa käsiteltiin massaräätälöintiä ja modulaarisuutta sekä tuotannonja tuotteiden kehittämistä yleisemmin. Tässä yhteydessä käsiteltiin muun muassaasiakastarvekartoitusta, kehityskohteiden valintaa ja ongelmanratkaisua. Esiintyviä ongelmia selvitettiin haastattelemalla toimitusprosessin avainhenkilöitä sekä suunnittelu-, myynti-, ja projektinjohtopuolelta että varsinaisen asennustyön suorittajien joukosta. Lisäksi tietoa hankittiin työmaakäynneillä ja keskustelemalla asentajien kanssa työkohteissa. Asennustyön suurimmaksi ongelmaksi osoittautuivat erilaiset tiedonkulun ongelmat, toimitetuissa asennustarvikkeissa olevat puutteet ja palautejärjestelmän puute. Kehitystoimenpiteiksi ehdotettiin ennakkotyön lisäämistä, muutoksia toimimattomiin käytäntöihin sekä yksinkertaisen palautejärjestelmän käyttöönottoa.

Glucose metabolism, gray matter structure, and memory decline in subjective memory impairment.

OBJECTIVE: To identify biological evidence for Alzheimer disease (AD) in individuals with subjective memory impairment (SMI) and unimpaired cognitive performance and to investigate the longitudinal cognitive course in these subjects. METHOD: [¹⁸F]fluoro-2-deoxyglucose PET (FDG-PET) and structural MRI were acquired in 31 subjects with SMI and 56 controls. Cognitive follow-up testing was performed (average follow-up time: 35 months). Differences in baseline brain imaging data and in memory decline were assessed between both groups. Associations of memory decline with brain imaging data were tested. RESULTS: The SMI group showed hypometabolism in the right precuneus and hypermetabolism in the right medial temporal lobe. Gray matter volume was reduced in the right hippocampus in the SMI group. At follow-up, subjects with SMI showed a poorer performance than controls on measures of episodic memory. Longitudinal memory decline in the SMI group was associated with reduced glucose metabolism in the right precuneus at baseline. CONCLUSION: The cross-sectional difference in 2 independent neuroimaging modalities indicates early AD pathology in SMI. The poorer memory performance at follow-up and the association of reduced longitudinal memory performance with hypometabolism in the precuneus at baseline support the concept of SMI as the earliest manifestation of AD.

Rakennus- ja talotekniikkaurakoitsijoille kehitettyjen CADsovellusten markkinapotentiaali Baltian maissa

Tutkimuksen päätavoitteena oli selvittää maakohtainen markkinapotentiaali urakoitsijoille kehitetyille CAD-sovelluksille eri Baltian maissa. Tämän laskemiseksitarvittiin tietoa rakentamisen arvoketjusta ja urakointimallista näillä alueilla. Näihin teemoihin liittyi myös läheisesti teoriakehykset markkinapotentiaalista, kansainvälistymisestä sekä arvoketjuajattelusta. Lisätavoitteena oli selvittää tarvittavat lokalisointi muutokset sovelluksiin. Nämä voivat liittyä esimerkiksi käytettäviin tuotemalleihin, kieleen, symboliikkaan, käyttöliittymään tai rekistereihin. Näihin kysymyksiin pyrittiin löytämään vastauksia urakointi- ja tukkuliikkeisiin suunnatuissa teemahaastatteluissa. Tutkimuksen tulosten pohjalta saatiin laskettua karkea arvio markkinapotentiaalista näillä markkina-alueilla, sekä kerättyä tietoa tarvittavista lokalisoinneista. Johtopäätöksissä esitetään suositus kansainvälistymismuodosta ja lisätutkimuksista.

Raeder's paratrigeminal syndrome due to spontaneous dissection of the cervical and petrous internal carotid artery.

The combination of pain, ipsilateral oculosympathetic defect (ptosis and miosis), and ipsilateral trigeminal dysfunction constitutes Raeder's syndrome. We describe a patient with an acute presentation of Raeder's syndrome due to spontaneous internal carotid artery dissection. True trigeminal dysfunction due to carotid dissection is rare, and the potential mechanisms for its involvement are reviewed in this paper. Finally, we remind clinicians to consider dissection in the differential diagnosis of Raeder's syndrome because of its potential for ischemic cerebral neurologic sequelae and suggest early cranial and neck imaging in the evaluation of such patients.

Severe ischemia of the hand following intra-arterial promazine injection: effects of vasodilation, anticoagulation, and local thrombolysis with tissue-type plasminogen activator.

Promazine hydrochloride was injected accidentally in the antecubital artery of a 42-year-old woman, resulting in severe ischemia of the second and third fingers of her right hand which lasted for four days before she was hospitalized. Vasodilation by combining axillary plexus block and intravenous sodium nitroprusside did not improve ischemia and local thrombolysis was performed using recombinant tissue-type plasminogen activator (50 mg over 8 hours), resulting in normalization of digital pressure in one of the two affected fingers. The outcome was favourable and amputation could be avoided.
