PENGEMBANGAN LKPD Qr Code IPA PADA MATERI TUMBUHAN SUMBER KEHIDUPAN DI BUMI MATA PELAJARAN IPAS KELAS IV SD

Based on the results of the analysis of grade IV students, teachers do not use technology during learning so that the learning carried out in class is monotonous even though students are familiar with technology. This causes students to experience boredom and decreased interest in learning in science learning itself. Based on this, researchers developed the Development of Qr Code LKPD Science on the Material for the Growth of Life Resources on Earth Science Subjects Class IV Elementary School. The purpose of this research is to produce Qr Code LKPD Science products on the Growth of Life Resources on Earth Science Subjects Class IV Elementary School. This type of research uses the ADDIE model and consists of five stages, namely analysis, design, development, implementation, and evaluation. The data collection techniques used were observation, interviews, questionnaires, and documentation. Based on the results of mteri experts obtained a percentage of 94%. While the results of expert validation of teaching materials obtained a percentage of 100%. Based on the assessment of validators, material experts and teaching material experts, it can be concluded that the Qr Code LKPD Science is very feasible for use by grade IV elementary school students. When the Qr Code LKPD Science is implemented, students give a positive response to teaching materials such as being more active in learning, students are also active in doing questions and answers with the right answers, students are also more enthusiastic about learning using Qr Code LKPD Science. This is evident from the data obtained by researchers, namely from the questionnaire the response of students gets 92% results, while the teacher's response gets a percentage of 100%. In addition, media effectiveness tests were also carried out to see the improvement in student learning outcomes after using the Qr Code LPKD Science by obtaining a percentage of 84%, so that it can be concluded that the LKPD Qr Code Science is effective and feasible to be used in learning Science material Plant Source of Life on Earth

In search of an evolutionary coding style

In the near future, all the human genes will be identified. But understanding the functions coded in the genes is a much harder problem. For example, by using block entropy, one has that the DNA code is closer to a random code then written text, which in turn is less ordered then an ordinary computer code; see \cite{schmitt}. Instead of saying that the DNA is badly written, using our programming standards, we might say that it is written in a different style -- an evolutionary style. We will suggest a way to search for such a style in a quantified manner by using an artificial life program, and by giving a definition of general codes and a definition of style for such codes.Comment: 14 pages, 7 postscript figure

The Meaning of Concepts of Human Nature in Organizational Life in Business Ethics Context

The main goal of this paper is to exhibit the role of the concept of human nature for the ethical orientation of organizational life. Therefore, after presenting some definitions of the concepts of human nature, which depict the complexity of these phenomena, some models of the concepts of human nature are described. Furthermore, the setting of the concepts of human nature in the organizational life is discussed. Those concepts can be perceived as a deep-structure of the organizational life, having an impact not only on the individual behaviour of employees and managers (like sensibility for human emotions, pro-social engagement, communication style), but also affecting their moral competence and influencing whole organizational culture – image of the organization, preferred management strategies and the way of perceiving justice. Those elements play crucial role in ethical attitude of the organization because all those variables support the efficacy of ethical rules and most of them are part of ethical code and corporate ethical code. Therefore, it is necessary for an organization to consider implicit and explicit concepts of human nature on which the organizational culture is based and support those concepts, which enables the ethical conduct of the organization and being alert especially to the consequences of materialistic/egoistic and competitive concepts of human nature. The theses discussed in the paper are supported by some empirical research studies conducted in this field.The National Science Centre (UMO-2011/03/D/HS4/00849
