Työn tavoitteena ovat valtakunnalliset liikenneturvallisuustavoitteet vuoteen 2020 mennessä ja niiden saavuttaminen tienpitäjän toimenpitein.Tässä työssä tarkasteltiin maanteitä, joilla on kesäaikana voimassa 100 km/h nopeusrajoitus. Työssä vertailtiin nykyisten 100 km/h väylien tierekisteritietoja uusiin nopeus-rajoitusohjeisiin (LVM:n yleisohje 2009) sekä vertailtiin ko. tiejaksojen onnettomuustiheyksiä ja -asteita valtakunnallisiin lukuihin (Liikennevirasto, 2012). Lisäksi 100 km/h tieosuuksien ympäristön asukastiheyttä tarkasteltiin Rakennus- ja huoneistorekisteritietojen perusteella. Näiden tietojen perusteella muodostuivat mahdolliset nopeusrajoituksen alentamista vaativat tiejaksot. Nopeusrajoituksen alentamista liikenneturvallisuustilanteen parantamiseksi tarkasteltiin seuraavien priorisointiperiaatteiden mukaisesti: 1. 0-vision ja ihmisen kestokyvyn mukainen priorisointi: • Millä 100 km/h tiejaksoilla ei ole keskikaidetta? 2. Vastaavatko 100 km/h tiejaksot nykyisiä nopeusrajoitusohjeita? 3. Esiintyykö 100 km/h tiejaksoilla korkeita onnettomuustiheyksiä ja -asteita? Varsinais-Suomen ELY-keskuksen liikennevastuualueen johtotiimin päätöksen mukaisesti nopeusrajoitusta alennetaan 80 km/h:iin yhteensä 23 kilometrin matkalla. Lisäksi talvinopeusrajoitusta alennetaan yhteensä 9 kilometrin pituisella tiejaksolla. Nopeusrajoitustoimenpiteiden lisäksi yhden liittymän kohdalle päätettiin asettaa ohituskiellot ja yhdelle tiejaksolle esitettiin tehtäväksi puuston raivausta. Toimenpiteillä saavutetaan noin 0,78 vuosittainen vähenemä henkilövahinkoon johtaneissa onnettomuuksissa. Toimenpiteiden yhteiskuntataloudelliset kustannukset ovat yhteensä 600 000 euroa/vuosi.

Epithelial ovarian cancer (EOC) is usually diagnosed in an advanced stage. The prognosis depends highly on the amount of the residual tumor in surgery. In patients with extensive disease, neoadjuvant chemotherapy (NACT) is used to diminish the tumor load before debulking surgery. New non-invasive methods are needed to preoperatively evaluate the disease dissemination and operability. [18F] FDG PET/CT (Positron emission tomography/computed tomography) is a promising method for cancer diagnostics and staging. The biomarker profiles during treatment can predict patient’s outcome. This prospective study included 41 EOC patients, 21 treated with primary surgery and 20 with NACT and interval surgery. The performances of preoperative contrast enhanced PET/CT (PET/ceCT) and diagnostic CT (ceCT) were compared. Perioperative visual estimation of tumor spread was studied in primary and interval surgery. The profile of the serum marker HE4 (Human epididymis 4) during primary chemotherapy was evaluated. In primary surgery, surgical findings were found to form an adequate reference standard for imaging studies. After NACT, the sensitivity for visual estimation of cancer dissemination was significantly worse. Preoperative PET/ceCT was more effective than ceCT alone in detecting extra-abdominal disease spread. The high number of supradiaphragmatic lymph node metastases detected by PET/ceCT at the time of diagnosis brings new insight in EOC spread patterns. The sensitivity of both PET/CT and ceCT remained modest in intra-abdominal areas important to operability. The HE4 profile was in concordance with the CA125 profile during primary chemotherapy. Its role in the evaluation of EOC chemotherapy response will be clarified in further studies.

Alzheimer’s disease (AD) is the most common form of dementia. Characteristic changes in an AD brain are the formation of β-amyloid protein (Aβ) plaques and neurofibrillary tangles, though other alterations in the brain have also been connected to AD. No cure is available for AD and it is one of the leading causes of death among the elderly in developed countries. Liposomes are biocompatible and biodegradable spherical phospholipid bilayer vesicles that can enclose various compounds. Several functional groups can be attached on the surface of liposomes in order to achieve long-circulating target-specific liposomes. Liposomes can be utilized as drug carriers and vehicles for imaging agents. Positron emission tomography (PET) is a non-invasive imaging method to study biological processes in living organisms. In this study using nucleophilic 18F-labeling synthesis, various synthesis approaches and leaving groups for novel PET imaging tracers have been developed to target AD pathology in the brain. The tracers were the thioflavin derivative [18F]flutemetamol, curcumin derivative [18F]treg-curcumin, and functionalized [18F]nanoliposomes, which all target Aβ in the AD brain. These tracers were evaluated using transgenic AD mouse models. In addition, 18F-labeling synthesis was developed for a tracer targeting the S1P3 receptor. The chosen 18F-fluorination strategy had an effect on the radiochemical yield and specific activity of the tracers. [18F]Treg-curcumin and functionalized [18F]nanoliposomes had low uptake in AD mouse brain, whereas [18F]flutemetamol exhibited the appropriate properties for preclinical Aβ-imaging. All of these tracers can be utilized in studies of the pathology and treatment of AD and related diseases.

The aim of this thesis is to search how to match the demand and supply effectively in industrial and project-oriented business environment. The demand-supply balancing process is searched through three different phases: the demand planning and forecasting, synchronization of demand and supply and measurement of the results. The thesis contains a single case study that has been implemented in a company called Outotec. In the case study the demand is planned and forecasted with qualitative (judgmental) forecasting method. The quantitative forecasting methods are searched further to support the demand forecast and long term planning. The sales and operations planning process is used in the synchronization of the demand and supply. The demand forecast is applied in the management of a supply chain of critical unit of elemental analyzer. Different meters on operational and strategic level are proposed for the measurement of performance.
