The main research purpose includes gaining understanding about the changes of living experiences of individuals in family and family as a whole post suicide over time; and gaining understanding about the differences between successful and unsuccessful cases for individuals and families in the grief process post suicide and the related causes underneath them. In practice, it is expected to apply the findings of this research to provide reference for psychological crisis intervention with suicide survivors particularly on how to meet the changing needs of mourning individuals and families.

In Yemen the number of maternal and infant mortality and morbidity remains high and more women become disabled as a result of pregnancy and childbirth complications. In addition, Yemen is among the country where female genital mutilation/cutting stills practice and many girls are undergo circumcise. The Project focuses on estimating the socioeconomic and other contributed factors of both maternal and child health outcomes including maternal mortality in the community setting as well as maternal health care seeking behavior. Also, the project investigates the prevalence and determinant factors for female genital mutilation/cutting

The foresight part of NEO-CARBON ENERGY explores possible futures of a new renewables-based energy production and storage system, which is being developed by VTT Technical Research Centre of Finland, Lappeenranta University of Technology (LUT) and University of Turku – Finland Futures Research Centre (FFRC). This joint research project is one of the strategic research openings of Tekes – The Finnish Funding Agency for Innovation. The foresight work is conducted in the Finland Futures Research Centre. A possibly distributed energy production system of neo-/low-carbon technologies and emerging issues such as prosumerism can drive economic, political, cultural and social changes. Radically new innovations, services and practices could emerge as a result of the third industrial revolution.

The production of hydrogen by solar energy is an attractive technique to realize global renewable energy supply. The photoinduced water splitting into hydrogen and oxygen by the direct use of sunlight is an ideal, renewable method of hydrogen production that integrates solar energy collection and water electrolysis into a single photoelectrode. Although the concept is attractive to produce sustainable fuel, the suitable electrode material (performance, stability and low cost) is yet to be found.

The widely-recognized essential features of the emerging 5G network compared with 4G networks include: 1000 times larger system capacity, 1/1000 power consumption, 10 Gbps peak rate and 1 ms end-to-end delay, while the innovation in transmission technologies is the basis in achieving this goal. The research carried out in this project can be divided into three areas: 1) New transmission architecture and protocol design for 5G networks 2) Green-transmission enabled 5G network technologies, 3) Advanced spectrum-sharing and smart transmission strategies in 5G networks. The proposed architectures, protocols, algorithms, techniques, and schemes are validated and evaluated through simulation platform and demonstration systems. Through this project, we expect to not only build theoretical foundations for 5G networks, but also to provide high-quality training opportunities for graduate students and engineers both in Finnish and Chinese Universities/Research Institutes.

Due the rapid increase in mobile and machine type data traffic the densities of networks are growing fast and deployment of local Ultra Dense Networks (UDNs) is seen as a viable solution in 5G framework. In this project we will consider the fundamental 5G challenges including 1) development of connectivity and control structures for high carrier frequency systems, 2) design of new low-latency, lowenergy 5G radio interface, 3) design of novel cooperative communication, beamforming and massive MIMO principles, 4) development of resource allocation principles for layered UDN deployment and 5) design principles enabling energy efficient UDN. We study these topics especially from indoor connectivity and machine type communication perspectives.

PET imaging with 18F-FDG has been shown to be sensitive and cost-effective for evaluating cancer patients at various phases such as diagnosis, staging, and therapy assessment. Typically, 18F-FDG is administrated to patients intravenously. 18F-FDG venous injection is simple and useful in clinical routine, but venous access cannot be established in all patients, such as cancer patients with a history of extensive chemotherapy. The primary purpose of the project was to investigate the dynamic process of 18F-FDG distribution after oral administration in order to determine the optimal imaging acquisition time in human subjects. Furthermore, we are planning to investigate the absorption function of small intestine by measuring the dynamic parameter of FDG after oral administration.

Carotid artery plaques are a leading cause of ischemic stroke, and carotid endarterectomy (CEA) is one of the major treatment approaches for this disease. Changes in cerebral metabolism following CEA remain unclear. The present study aimed to evaluate the effect of cerebral ammonia metabolism following CEA using 13N labeled ammonia positron emission tomography (PET) in humans. This is clinical study in human subjects. This is an international collaboration project. Since Turku PET Centre has very strong PET research experiences, we provides the research protocols to China. Partners in China performed clinical investigations based on our protocols. Furthermore, we performed data analysis and manuscript writing.

Vascular adhesion protein-1 (VAP-1) is an adhesion molecule and involved in leukocyte rolling, adhesion, and transmigration from the blood into sites of inflammation, which is important for the pathogenesis of atherosclerosis. VAP-1 was found and identified in Turku by Prof. Sirpa Jalkanen. In this study, we planed to investigate the relationship soluble VAP-1(sVAP-1) in serum with cardiovascular factors based on Chinese population. This is an internation collaboration project. Finland provides technical supports and VAP-1 antibodies to China. Parters in China performed population study.

The purpose of research is to develop and validate a novel system for quantitative assessment of multi-organ tissue-perfusion using a dedicated cyclotron-produced, short-lived nuclei of 15O and PET for non-invasive human and small animal studies. This system is to overcome organ-specific problems. The goal is to establish a standard package for quantitative assessment of tissue perfusion, involving ICT-based multi-modality image processing techniques.
