    Tässä kvalitatiivisessa pro gradu -tutkielmassa tutkin luovuuden tukemisen merkityksiä. Tutkimus sisältää kolme narratiivista haastattelua ja niistä syntyneet kertomukset luovuuden tukemisen merkityksistä. Toinen tutkimuksessa käytetty metodi on systemoitu kirjallisuuskatsaus, jossa tärkeimmiksi teorioiksi on valittu J. P. Guilfordin divergentti ajattelu, A. H. Maslow’n teoria luovuudesta itsensä toteuttamisena ja M. Csíkszentmihályin flow-teoria. Luovuuden tukemisen merkityksiä voidaan löytää niin yksilön kuin yhteiskunnan näkökulmista. Tämän tutkimuksen parasta antia ovat luovuuskertomukset, joita analysoin muun muassa rohkeuden, vapauden, ideoinnin ja itsevarmuuden rakentumisen näkökulmista. Yhteiskunnallisia näkökulmia tutkimukselle on luovien produktien tuottaminen ja yhteiskunnallinen osallistuminen.

    Previous studies indicate that positive learning experiences are related to academic achievement as well as to well-being. On the other hand, emotional and motivational problems in studying may pose a risk for both academic achievement and well-being. Thus, emotions and motivation have an increasing role in explaining university students learning and studying. The relations between emotions, motivation, study success and well-being have been less frequently studied. The aim of this study was to investigate what kind of academic emotions, motivational factors and problems in studying students experienced five days before an exam of an activating lecture course, and the relations among these factors as well as their relation to self-study time and study success. Furthermore, the effect of all these factors on well-being, flow experience and academic achievement was examined. The term academic emotion was defined as emotion experienced in academic settings and related to studying. In the present study the theoretical background to motivational factors was based on thinking strategies and attributions, flow experience and task value. Problems in studying were measured in terms of exhaustion, anxiety, stress, lack of interest, lack of self-regulation and procrastination. The data were collected in December 2009 in an activating educational psychology lecture course by using a questionnaire. The participants (n=107) were class and kindergarten teacher students from the University of Helsinki. Most of them were first year students. The course grades were also gathered. Correlations and stepwise regression analysis were carried out to find out the factors that were related to or explained study success. The clusters that presented students' problems in studying as well as thinking strategies and attributions, were found through hierarchical cluster analysis. K-means cluster analysis was used to form the final groups. One-way analysis of variance, Kruskal-Wallis test and crosstabs were conducted to see whether the students in different clusters varied in terms of study success, academic emotions, task value, flow, and background variables. The results indicated that academic emotions measured five days before the exam explained about 30 % of the variance of the course grade; exhaustion and interest positively, and anxiety negatively. In addition, interest as well as the self-study time best explained study success on the course. The participants were classified into three clusters according to their problems in studying as well as their thinking strategies and attributions: 1) ill-being, 2) carefree, and 3) committed and optimistic students. Ill-being students reported most negative emotions, achieved the worst grades, experienced anxiety rather than flow and were also the youngest. Carefree students, on the other hand, expressed the least negative emotions and spent the least time on self-studying, and like committed students, experienced flow. In addition, committed students reported positive emotions the most often and achieved the best grades on the course. In the future, more in-depth understanding how and why especially young first year students experience their studying hard is needed, because early state of the studies is shown to predict later study success.

    Flow experience is often defined either as an experience of high concentration and enjoyment or as a situation, where high challenges are matched with high skills. According to core-emotion theories, the experience of any emotion contains two core emotions: valence and arousal. Through an accurate mathematical model, the present study investigated, whether the experience of concentration and enjoyment is related to situations where both challenge and skills are high and in balance. Further, it was investigated what sort of core emotions are related to differing relationships between challenge and skills. Finally, university students' experiences of their natural study environments were described in terms of core emotions and in terms of relationships between challenge and skills. Participants were 55 university students who participated two weeks research period. Altogether 3367 questionnaire answers were collected with the CASS experience-sampling method, operating in 3G-mobile phones. The relationship between challenge and skills (competence) was defined in an exact way in polar coordinates. An enjoyable and concentrated flow experience was defined as a sum variable of absorption, interest and enthusiasm. Core emotions were calculated with factor analysis from nine emotion variables. As expected, an experience of concentration and enjoyment was, on average, related to the situations where both challenge and skills were high and in balance. This was not, however, the case in every situation. Thus, it should be taken into consideration how flow experience is operationalised in experience sampling studies. When flow experience was defined as a situation of high challenge and high skills, it was often related to high valence and arousal emotions such as excitement or enthusiasm. A happier or a more tranquil enjoyment was related to situations of moderate challenge and high skills. Experiences differed clearly between various natural study environments. At lectures students were often bored or mentally absent, and did not experience challenges. In a small group students were often excited or enthusiastic, and showed optimal balance between challenge and skills. At library students felt satisfied and were engaged in highly challenging work.

    Traditional 2D cell cultivating vessels and experimental models cannot often simulate natural chemical and physical environment of different cell types. For example, availability of oxygen, chemical gradients, messaging molecules, fluid pressure, flow and surface topography are factors that may affect significantly in cell differentiation, growth, cellular structure, and metabolism. Modular bioreactors like Quasi-Vivo® -system can be used to simulate these factors. Liposomes are particles of phospholipid bilayer with aqueous space enclosed within. They can be modified in numerous ways, like loading them with hydrophobic and hydrophilic molecules, changing their transition temperature or coating them according to different needs. Doxorubicin is effective and widely used cytostatic agent, but when administered as a free drug it has often severe side-effects, like cardiotoxicity. Goal of this thesis is to determine appropriate manufacturing parameters and verify adequate shelf-life of ICG-Doxorubicin liposomes, that they are applicable for future in vitro experiments. Then survival of HepG2 cell line under flow in Quasi-Vivo®-equipment is determined, after which A549 and HepG2 will be then combined into one two-cell model. Finally, a simple illumination experiment in this cell model with previously made liposomes is conducted, and the effect in whole system is examined. Using protocol presented in this thesis it is possible to produce successfully and repeatedly liposomes with both ICG and doxorubicin encapsulation over 70%. Their shelf-life was at least 14 days when stored in 4°C protected from light. This was determined to be sufficient for in vitro testing. Cultivating A549 and HepG2 cell lines combined in the same system with shared media and fluid flow conditions was successful. Neither of the cell lines show significant difference in viability when compared to static control. When light-activating liposomes are administered to the system and then illuminated, from preliminary results we can see significant difference in drug effect. Both illuminated chambers and off-target chambers connected via Quasi-Vivo® show increased suppression, which shows promise that this in vitro model would be useful for future experiments.

    This study explored the possibilities the psychophysiological methodology offer to flow research. Facial electromyography has often been used to index valence, and electrodermal activity to index arousal, the two basic dimensions of emotion. It was hypothesized that these measures can also be used to examine enjoyment, a basic component of flow experiment. A digital game was used to induce flow, and physiological activity of 32 subjects was measured continuously. Flow State Scale was used to assess flow. Activity of corrugator supercilii muscle, an index of negative valence, was negatively correlated with flow reports, as hypothesized. Contrary to hypothesis, skin conductance level, an index of arousal, was unrelated to self-reported flow. The results for association between flow and zygomaticus major and orbicularis oculi muscle activities, indices of positive valence, were inconclusive, possibly due to experimental design where only tonic measures were available. Psychophysiological methods are recommended for future studies of flow. Specifically, the time series approach may be particularly viable in examining the temporal aspects of flow, an area currently unexplored. Furthermore, it is suggested that digital game research would benefit from psychophysiological study of game-related flow.

    While natural language generation (NLG) and large-language models (LLM) seem to be transforming many industries, video games have yet to be affected. This study investigates the potential of using NLG systems to generate dialogue for non-playable characters (NPCs) in role-playing games (RPGs). For this, dialogue data is extracted from six popular RPGs and is then used to fine-tune Microsoft’s GODEL to create an “RPG chatbot” (RPG-GPT). Motivated by computational creativity frameworks, a survey and an interactive experiment were conducted to evaluate the creativity and the effectiveness of RPG-GPT in generating relevant and engaging responses to player input. Survey respondents rated dialogues on a 5-point agree-disagree Likert scale, with questions related to e.g. the relevance of the NPC answers. Results indicate that RPG-GPT can provide relevant responses with a mean difference of game relevance of 3.93 vs. 3.85 of RPG-GPT (p=0.0364). Also, the participants of the interactive experiment reported engagement when interacting with RPG-GPT. Overall, the results suggest that creative NLG has the potential to enhance gaming experiences through task-oriented game dialogue (TOGD) systems. In this framework, creative TOGD systems could solve a common issue where pre-written NPCs are unable to provide the specific information sought by players. Additionally, the study discusses a concept of how players through their interaction with the NLG models can expand the lore of a game, which is a new consideration for game designers and developers when implementing such systems. Future work could explore ways to incorporate external knowledge and context to improve the performance of a TOGD system.

    Recent studies show that motivation, emotion, and interest are engaged in learning. Engagement to learning is a complex entity in which the dynamic interaction between the student and the learning environment is central. In addition, students` ability to influence their own learning, mutual cooperation, and meaningful experience in learning strengthens engagement in learning. Recent curriculum on behalf of transversal competence underlines central meaning of these factors in teaching. This is also topical, as the learning outcomes and motivation of children and young people have fallen in recent years. The purpose of this thesis is to study the factors involved engagement in comprehensive school setting during science learning project on 5.–6. grades. The data (n = 74) was collected in spring 2018 from a local school in a metropolitan area during the phenom-enal science learning process in classes 5–6, which was carried out according to inquiry-based learning. The Experience Sampling Form was developed for this thesis in order to study the students' internal experiences during the learning process. Students responded to the questionnaire six times during the five-week working pe-riod, and field notes were also used during analysis of the thesis. Experience Sampling data was used to gener-ate sum variables (motivation, academic emotions, and interest factors), the interconnection was examined by the Spearmans` rank correlation coefficient. On the second phase, the link between the variables and the stages of work (inquiry based learning) was examined by the Kruskall Wallis test and the paired Mann-Whitney U test. The connection between variables and working methods (researching team, whole class) were examined with Cross-Tabulation Analysis, also observations from field notes were produced and compared with the work stages (teacher guidance, information retrieval, evaluation). The formed variables´ correlation is statistically significant to a large extent with each other, so it is justified to investigate these synergies. On the other hand there were no statistically significant differences between work phases and variables, exception was apathy variable, which had statistically significant difference be-tween question making and evaluation. In terms of working habits, students' experiences (somewhat, much) were evenly distributed with activity, insertion and ability variables. Apathy was less experienced and student experienced both ways of working mainly rewarding. Experience of import was less experienced during the en-tire class work and student had less autonomy experience during both working methods. According to findings, interaction and concentration were the most abundant during the work of the research team. The results of this thesis confirm that learning is not about individual factors, but about the complex process of the student and the learning environment. In addition, the students' ability to actively influence their own work and the students’ mutual work reinforce engagement in learning. In summary, it can also be said that phe-nomenal learning according to inquiry-based learning strengthens students' autonomy, interaction and engage-ment to learning. This is significant, because the current curriculum in particular challenges the implementation of teaching to be more cooperative. However, more information about learning is still needed. The purpose of this thesis could be applied more widely in the field of education research so that the engagement in learning could be explored longer term and in among several classes.
