Robotin ohjelmointi on aikaa vievää ja tarvitsee robotin ohjelmoinnin tuntevan operaattorin toimimaan robotin opettajana. Saadakseen robottisolun kustannustehokkaaksi operaattorilla olisi hyvä olla useampi solu hoidettavanaan samaan aikaan. Tämä ei ole suuri ongelma suurille yrityksille, joissa voi olla kymmeniä robottisoluja. Jos kyseessä on pieni tai keskisuuri yritys, automatisointi-investointi voi jäädä tekemättä ohjelmoinnin vaikeuden aiheuttaman ongelman vuoksi. Diplomityössä keskityttiin tutkimaan robotisointia pienten ja keskisuurten yritysten kannalta. Teoriaosassa on keskitytty robottisolun suunnittelun kannalta tarvittaviin perustietoihin robotin rakenteesta, ohjausjärjestelmästä, ohjelmoinnista sekä turvallisuudesta. Näiden perustietojen lisäksi on huomioitu hitsauksen automatisointia sekä taluttamalla ohjelmoitavan robottisolun tekninen konsepti. Taluttamalla ohjelmoitavan robottisolun konseptin käsittelyosassa on myös perehdytty taluttamalla ohjelmoinnin vaatimiin komponentteihin kuten voima/vääntö-anturi. Robottisolun suunnittelu on tehtävä koneasetuksen vaatimusten mukaan. Turvallisuus osiossa on käsitelty koneasetuksen vaatimuksia koneensuunnittelulle ja käytännön osassa on käsitelty Winnovan taluttamalla ohjelmoitavan robottisolun suunnittelua koneasetuksen ohjeiden mukaan. Käytännön osassa on tutkittu taluttamalla ohjelmoinnin tuomia etuja muihin ohjelmointimenetelmiin nähden sekä suoritettu investointilaskelmat taluttamalla ohjelmoitavasta ja opettamalla ohjelmoitavasta robottisolusta. Koetuloksista nähdään taluttamalla ohjelmoinnin olevan nopeampi ja yksinkertaisempi tapa ohjelmoida robottia kuin opettamalla ohjelmointi. Investointilaskelmien vertailusta nähdään taluttamalla ohjelmoinnin tulevan opettamalla ohjelmointia edullisemmaksi vaihtoehdoksi käyttökustannusten edullisuuden ansiosta.

The purpose of this study was to analyze nursing ethics education from the perspective of nurses’ codes of ethics in the basic nursing education programmes in polytechnics in Finland with the following research questions: What is known about nurses’ codes in practice and education, what contents of the codes are taught, what teaching and evaluation methods are used, which demographic variables are associated with the teaching, what is nurse educators’ adequacy of knowledge to teach the codes and nursing students’ knowledge of and ability to apply the codes, and what are participants’ opinions of the need and applicability of the codes, and their importance in nursing ethics education. The aim of the study was to identify strengths and possible problem areas in teaching of the codes and nursing ethics in general. The knowledge gained from this study can be used for developing nursing ethics curricula and teaching of ethics in theory and practice. The data collection was targeted to all polytechnics in Finland providing basic nursing education (i.e. Bachelor of Health Care). The target groups were all nurse educators teaching ethics and all graduating nursing students in the academic year of 2006. A total of 183 educators and 214 students from 24 polytechnics participated. The data was collected using a structured questionnaire with four open-ended questions, designed for this study. The data was analysed by SPSS (14.0) and the open-ended questions by inductive content analysis. Descriptive statistics were used to summarize the data. Inferential statistics were used to estimate the differences between the participant groups. The reliability of the questionnaire was estimated with Cronbach’s coefficient alpha. The literature review revealed that empirical research on the codes was scarce, and minimal in the area of education. Teaching of nurses’ codes themselves and the embedded ethical concepts was extensive, teaching of the functions of the codes and related laws and agreements was moderate, but teaching of the codes of other health care professions was modest. Issues related to the nurse-patient relationship were emphasised. Wider social dimensions of the codes were less emphasized. Educators’ and students’ descriptions of teaching emphasized mainly the same teaching contents, but there were statistically significant differences between the groups in that educators assessed their teaching to be more extensive than what students had perceived it had been. T he use of teaching and evaluation methods was rather narrow and conventional. However, educators’ and students’ descriptions of the used methods differed statistically significantly. Students’ knowledge of the codes and their ability to apply them in practice was assessed as mediocre by educators and by students themselves. Most educators assessed their own knowledge of the codes as adequate to teach the codes, as did most of the students. Educators who regarded their knowledge as adequate taught the codes more extensively than those who assessed their knowledge as less adequate. Also students who assessed their educators’ knowledge as adequate perceived the teaching of the codes to be more extensive. Otherwise educators’ and students’ demographic variables had little association with their descriptions of the teaching. According to the participants, nurses need their own codes, and they are also regarded as applicable in practice. The codes are an important element in nursing ethics education, but their teaching needs development. Further research should focus on the organization of ethics teaching in the curricula, the teaching process, and on the evaluation of the effectiveness of ethics education and on educators’ competence. Also the meaning and functions of the codes at all levels of nursing deserve attention. More versatile use of research methods would be beneficial in gaining new knowledge.

In general, the traditional Physics courses needs examples of the aplications of the Physics concepts in other areas such as Chemistry and Biology. This lacks tend to demotivate Chemistry and Biology students regarding to deal with Physical concepts developed in classroom. In this work, the analogy among mechanic and electric oscillators is investigated to be applied in Chemistry and Biology areas, showing to be valuable due to its aplication in techniques that aims to measure mass variation with high precision. This measure could be made in a direct or indirect way. These techniques are known as electrogravimetric techniques and they are important in biosensor aplications. Thus, this paper explores the electromechanic analogy in an interdisciplinary way involving areas like Physics, Chemistry and Biology. Based on this analogy, it is proposed an experiment that can be applied in different ways, i.e. by an basic approach or more deeper, depending on the students specific formation, in other words, Physics, Chemistry or Biology.

O presente trabalho investiga a degradação fotoeletrocatalítica do corante Azul Básico 41 (AB 41) amplamente utilizado na tintura de fibras sintéticas, utilizando um semicondutor Ti/TiO2 como fotoanodo. 100% de degradação foi obtida após 60 min de tratamento de 8,33x10-5 mol L-1 do corante em 0,1 mol L−1 Na2SO4, pH 2 sob densidade de corrente de 0,40 mA cm−2 e irradiação UV. Ainda foi obtido 80% de remoção de carbono orgânico total, cuja oxidação segue uma reação de pseudo-primeira ordem com constante de velocidade inicial de -0,040 mim-1 e uma eficiência de corrente de 51%. Os resultados são superiores á fotocatálise convencional nas mesmas condições sem a polarização do fotoanodo que leva a 65% de mineralização sob constante de velocidade de -0,024 mim-1.

The main aim of the study is to elucidate the meaning and dimensions of the concept of „virtue‟, and to find the place of virtue in a caritative caring ethics, i.e. a caring ethics based on human love and mercy. The intention is to create a theory model which utilizes the possibilities of virtue in developing the caritative caring ethics as a whole. The caritative caring ethics has a universal potential – it is primarily not a professional ethics, but it may form a frame of reference and basis for formulating ethical codes, and for ethical discussions within different caring contexts. The hermeneutic approach of the study is inspired by Gadamer‟s philosophical hermeneutics combined with the view of hermeneutics as a hypothetical-deductive process. The study is guided by Eriksson‟s model of definition of concepts. The concept of „virtue‟ is studied focusing on its ethical dimensions. These ethical dimensions of virtue are seen as anchored to an inner ethos, whereas ethos stands for the ontological goodness, a basic notion of the Good that permeates the entity of the human being, and forms the base of the culture where he lives and acts. The overarching research questions are: 1. What is virtue? 2. What is „virtue‟ as a basic concept in caring science? 3. What place does virtue have in caritative caring ethics? The answer of the first question is mainly searched for by an ontological determination comprising partly an etymologic and semantic analysis of „virtue‟, and partly a determination of the essence of virtue. The answer to the second and third questions are mainly searched for using a contextual determination, where the purposive context and pragmatic features of virtue are studied in relation to caring ethics. The ontological and contextual determinations are brought together through hermeneutical interpretation, forming a new whole, which constitutes the results of the study. The results of the study are depicted in a theory model, in which the movement of virtue from ethos to deed is moulded as caritative caring ethics. The material of the study consists of dictionaries, texts written by Aristotle and St. Thomas Aquinas, articles, dissertations, and books, as well as parts of a pilot survey answered by 33 nurses. The results of the study show that the essence of virtue is primarily functional, not ethical. The ethical emerges when virtue is contextualized in a human communion. Virtue makes something fulfil its function well; makes the human being good, and gives him morals and morality. The human being needs prudence, love, and humility to acquire and develop the moral virtues. Virtue is a power, related to a value, which considering a caritative caring ethics consists of the caritas motif. Human love is shown through deeds, making the human being do what he is expected to do. Virtue, as an active power of becoming, affirms and clarifies the human being‟s ability to develop in the direction of the Good. Virtue becomes essential and unifying when morality appears in the human mind as auctoritas, an inner, prompting power based on divinity or a transcendental ethos. Together ethos and virtue create opportunities for an inner ethics based on voluntariness and joy in being and doing the true, the good, and the beautiful.
