Remote Condition Monitoring and Asset Management in Offshore Power Systems

Condition monitoring systems for physical assets are constantly becoming more and more common in the industrial sector. At the same time an increasing portion of asset monitoring systems are being remotely supported. As global competitors are actively developing solutions for condition monitoring and condition-based maintenance, which it enables, Wärtsilä too feels the pressure to provide customers with more sophisticated condition-based maintenance solutions. The main aim of this thesis study is to consider Wärtsilä remote condition monitoring solutions and how they relate to similar solutions from other suppliers and end customers’ needs, in the context of offshore assets. A theoretical study is also included in the thesis, where the concepts of condition monitoring, condition-based maintenance, maintenance management and physical asset management are introduced.

Utilizing social media in software documentation and knowledge management

This Master’s thesis studies the possibilities that social media tools can bring to help knowledge management in software development companies. It will introduce the most popular tools of social media and their usage possibilities in companies, not forgetting the possible downsides. One relevant aspect in this study is to investigate the possibilities of social media to help converting existing tacit knowledge into explicit. The purpose of the work is to create a proposal of social media utilization for a mid-sized software company, which has not utilized social media tools before. To be able to create the proposal, employees of the company are interviewed and a survey is executed to analyze the current situation. In addition a pilot project for trying out new social media tools is executed. The final result of this thesis introduces a tailored solution for the target company to start utilizing social media in its documentation and knowledge sharing processes. This new solution consists of multiple individual suggestions that are categorized and prioritized based on the significance and benefit that they bring to the company.

Role of Capabilities in Purchasing and Supply Management Performance

The objective of this thesis was to study the role of capabilities in purchasing and supply management. For the pre-understanding of the research topic, purchasing and supply management development and the multidimensional, unstructured and complex nature of purchasing and supply management performance was studied in literature review. In addition, a capability-based purchasing and supply management performance framework were researched and structured for the empirical research. Due to the unstructured nature of the research topic, the empirical research is three-pronged in this study including three different research methods: the Delphi method, semi-structured interview, and case research. As a result, the purchasing and supply management capability assessment tool was structured to measure current level of capabilities and impact of capabilities on purchasing and supply management performance. The final results indicate that capabilities are enablers of purchasing and supply management performance, and therefore critical to purchasing and supply performance.

Aggression and its Management in Adolescent Forensic Psychiatric Care

The overall goal of this study was to explore and identify good aggression management methods and on that basis to produce recommendations for aggression management in the adolescent forensic setting. The study was conducted in three phases. In Phase I, staff’s (n = 58) perception of adolescent aggressive behaviour and methods to manage it was examined. In Phase II, staff’s (n = 30) perception of treatment settings and treatment interventions available were studied. In Phase III, the effectiveness of an aggression management programme was evaluated. The data were collected during the period 2004-2007. Participants perceived adolescent aggressive behaviour in a similar way and described aggressive behaviour as being a comprehensible phenomenon. Management methods used to control aggressive situations were alike, although the practical solutions varied between the study units, especially regarding coercive methods. Staff members proposed more time and better opportunities to discuss and evaluate the aggression situation in order to improve the methods used. The treatment settings were similar in studied forensic units and interventions were primarily focused on psychological aspects, including management of aggressive behavior. A comprehensive aggression management programme proved to be effective in decreasing incidents of violence. The use of coercive methods in aggression situations decreased and injuries to the staff became less frequent. If staff members intend to apply high quality management methods in aggression situations they have to share a consistent understanding of aggressive behaviour and need to be aware of the various methods available. In addition, they should learn more about assessment methods in order to improve aggression management. International comparison of aggression, methods for managing it and service provision creates a starting point for developing equal care provision and realization within and between European countries.

Establishment of a health and safety management system according to the OHSAS 18001 standard

The thesis develops guidelines for the implementation of the health and safety management system according to the OHSAS 18001 standard, as well as the feasible threat analysis, project proposal schedule, future system quality improvements and organizational change evaluation. The theoretical part clarifies determination of occupational health and safety, its management system, the OHSAS 18001 standard and integrated management system compounded of triple ISO 14001, ISO 9001 and OHSAS 18001 standards. The literature includes such important aspects as human factor, organizational policies, possible benefits, threats, organizational safety culture, Deming’s quality improvement cycle, system implementation, maintenance and cost matters. The empirical part demonstrates real-life situation by using Andritz Pulp & Paper Oy as a case study. Prior the thesis proposal, Andritz Group is analysed including separate business areas, acquisition and integration strategies, current status of the health and safety management and parallel experiences of the largest business area Andritz Hydro. The proposal is aimed at improving the current health and safety system for the permanent and sub-contracted employees at Andritz Pulp & Paper both in Finland and in various projects globally.

Violations of children's rights in armed conflicts : international treaties, observations by peacekeepers and crisis management training in Finland

Ninety-nine Finnish peacekeepers, who had been serving in 15 different operations around the world, participated in the study (8 women, 27-52 years old, m = 37.4, SD = 8.9; and 91 men, 21-69 years old, m = 41.4, SD = 10.2). Three military crisis management trainers from the Finnish Defence Forces International Centre also participated in the study. The data was collected with two webbased questionnaires. In addition two interviews were made with specialists of civilian crisis management in Finland. The study also provides an overview of international treaties concerning children’s rights in armed conflict. The results show that 48.7 % of dangers for children in conflicts reported by the peacekeepers were related to physical injury (e.g. landmines and traffic), and 27.4 % were related to social problems (e.g. poverty, child soldiers, and trafficking). 24.1 % of the peacekeepers had made observations of children’s rights violations either often or very often during peacekeeping operations. 49.6 % of the observations were related to social problems (e.g. child labour or being forced to beg), and 33.0 % were related to physical injury (e.g. assault). Frequency of observation of children’s rights violations was not associated with either sex or military degree of the peacekeepers; instead it was significantly correlated with the peacekeepers’ degree of knowledge of EU’s child protection guidelines. On the basis of the results, it is recommended that knowledge about children’s rights and protection should be included in the training of Finnish crisis management personnel to a much higher degree than at the present.

Upland rice yield as affected by previous summer crop rotation (soybean or upland rice) and glyphosate management on cover crops

The appropriate chemical management of cover crops in no-tillage aims to obtain greater benefits with its employment in agricultural systems. The objective of this study was to assess upland rice yield as affected by the previous summer crop, species and desiccation timing of cover crops by glyphosate. Sown cover crops were sown (November 2007), followed by rice in half of the experimental area and soybean in the other half (November 2008). After the harvesting of these crops, the same cover crops were sown again (March 2009) and followed by upland rice in the total area (November 2009). The experiment consisted of the combination of five cover crops (fallow, Panicum maximum, Brachiaria ruziziensis, B. brizantha and Pennisetum glaucum), four desiccation timings (30, 20, 10 and 0 days before rice sowing), and two antecedents of the summer crop (rice or soybean) under no-tillage system (NTS), plus two control treatments at conventional tillage system (CTS). Cover crops significantly affect rice grain yield and its components. There is a significant tendency to highest yield when cover crop desiccation is conducted farther from the rice sowing date (from 2,577.1 kg ha-1 - desiccation at rice sowing to 3,115.30 kg ha-1 - desiccation 30 days before rice sowing). Soybean as an antecedent of summer crop allows better upland rice yield (3,754 kg ha-1) than rice as an antecedent of summer crop (2,635 kg ha-1); fallow/soybean/fallow (4,507 kg ha-1) and millet/soybean/millet (4,765 kg ha-1) rotation at no-tillage system, and incorporated fallow /soybean/ incorporated fallow (4,427 kg ha-1) at conventional tillage system allow the highest rice yield; upland rice yield is similar at no-till (3,194 kg ha-1) and till system (2,878 kg ha-1).

Anaesthesia and Pain Management for Use in Orthopaedic Day Surgery

Day surgery has gained a large popularity during the last decades. In Finland, 57% of the elective procedures, and 50% at Turku University Hospital, were already conducted on day basis during 2012. The steady growth of day surgery is mostly due to an increased safety in perioperative care and cost-effectiveness. The development of surgical techniques and anaesthetic methods has advanced the modern day surgery and extended the repertory of the procedures for use in day surgery operations. Day surgery also offers certain benefits like reduced risk for hospital-related infections, stress and confusion. Patient satisfaction, regarding several issues, is high. Most concerns and complaints are related to postoperative pain, nausea and vomiting pain and nausea. Pain can hamper recovery and pain management is a crucial factor for hospital discharge. Appropriate pain treatment is effective, safe, easy and economical. A procedure-specific approach and an individually planned, multimodal analgesia should be the basis of modern pain management. The main aim of this thesis was to evaluate the effectiveness and safety of anaesthetic technique and methods in pain treatment of orthopaedic day case surgery, and following conclusions were made. Unilateral spinal block was achieved using hyperbaric bupivacaine with a small dose of clonidine but clonidine prolonged the block. Continuous subacromial bupivacaine was found to be safe but conferring only moderate efficacy in pain care after shoulder arthroscopy. Transdermal fentanyl, 12 g/h, as part of multimodal analgesia, offered a safe and easy option to pain management in this patient group. However, after forefoot surgery, it did not reduce pain any further. In general, pain scores in all patient groups were low and the need for rescue opioid moderate.

Foreign Direct Investment, Clean Development Mechanism, and Environmental Management: A case of Sub-Saharan Africa

This doctoral dissertation explores the contribution of environmental management practices, the so-called clean development mechanism (CDM) projects, and foreign direct investment (FDI) in achieving sustainable development in developing countries, particularly in Sub- Saharan Africa. Because the climate change caused by greenhouse gas emissions is one of the most serious global environmental challenges, the main focus is on the causal links between carbon dioxide (CO2) emissions, energy consumption, and economic development in Sub-Saharan Africa. In addition, the dissertation investigates the factors that have affected the distribution of CDM projects in developing countries and the relationships between FDI and other macroeconomic variables of interest. The main contribution of the dissertation is empirical. One of the publications uses crosssectional data and Tobit and Poisson regressions. Three of the studies use time-series data and vector autoregressive and vector error correction models, while two publications use panel data and panel data estimation methods. One of the publications uses thus both timeseries and panel data. The concept of Granger causality is utilized in four of the publications. The results indicate that there are significant differences in the Granger causality relationships between CO2 emissions, energy consumption, economic growth, and FDI in different countries. It appears also that the causality relationships change over time. Furthermore, the results support the environmental Kuznets curve hypothesis but only for some of the countries. As to CDM activities, past emission levels, institutional quality, and the size of the host country appear to be among the significant determinants of the distribution of CDM projects. FDI and exports are also found to be significant determinants of economic growth.

Competence foresight: linking the identification of HR competences and competence management alignment with business strategy

The objective of this study was to increase understanding of the link between the identification of required HR competences and competence management alignment with business strategy in a Finnish, global company employing over 8,000 people and about 100 HR professionals. This aim was approached by analyzing the data collected in focus group interviews using a grounded theory method and in parallel reviewing the literature of strategic human resource management, competence-based strategic management, strategy and foresight. The literature on competence management in different contexts dismisses in-depth discussions on the foresight process and individuals are often forgotten in strategic frameworks. However, corporate foresight helps in the detection of emerging opportunities for innovations and in the implementation of strategy. The empirical findings indicate a lack of strategic leadership and an alignment with HR and business. Accordingly, the most important HR competence areas identified were the need for increasing business understanding and enabling change. As a result, the study provided a holistic model for competence foresight, which introduces HR professionals as strategic change agents in the role of organizational futurists at the heart of the company: facilitating competence foresight and competence development on individual as well as organizational levels, resulting in an agile organization with increased business understanding, sensitive sensors and adaptive actions to enable change.
