By obtaining changes on gene sequences of living things with the applied biotechnological methods; The idea of "Genetically Modified Organisms (GMO)", which aims to bring the living creature in question the original gene combinations with the desired characteristics, came to life in the late twentieth century. Despite the high probability that hunger problems may increase with the increasing world population; It is thought that plant breeding with classical farming methods will be insufficient in solving these problems. With various GMO applications developed all over the world, it aims to produce solutions to these problems. With the presence of GMO, it was possible to increase the shelf life of qualitative and quantitative values of the existing foods. In addition, decreases in agricultural use of pesticides used in agricultural struggle and threatening human health with GMO production are noteworthy. However, some concerns about anomalies that may occur in living things fed GMO products remain on the agenda. Because, in the long term, there is no clear and precise information that GMO will not have negative effects on living things; There are many recorded incidents showing their negative effects.

We present the study of one of the great projects of the Barcelona publisher Editorial Labor, namely the Diccionario de Pedagogía (1936), from a new perspective: the analysis of entries on the teaching of scientific subjects. The axis of the methodologies proposed by the work is the study of living things in their natural environment from an ecological perspective, both outside the classroom via excursions and inside through aquaria, terraria, herbaria and school kitchen gardens. These methodologies can be seen to have been be influenced by New Education principles, the English Nature Study movement and the Spanish Institución Libre de Enseñanza. Coordinated by Luis Sánchez Sarto, the Diccionario de Pedagogía recorded the state of pedagogy and education worldwide, counting on a hundred or so anonymous authors most of whom were German, Austrian, American or Spanish. John Dewey, Vilhelm Rasmussen and Georg Kerschensteiner are the dictionary’s pedagogical references in science teaching. In our article, we present arguments suggesting that Margarita Comas Camps and Rafael Candel Vila were the authors of the dictionary’s two entries on teaching methodology.

School Perceptions

This study aims to determine the science teacher of elementary school perceptions in learning science with practical methods. Research carried out by the method blending, mixing qualitative and quantitative. The subjects of the study were Science Teacher and head of MIN (elementary school) Aceh Jaya District. The instrument used was in the form of a teacher’s perception questionnaire which was arranged based on a Likert scale and a list of interview questions. The results showed that the perception of teachers in “very good” category was 92% and the remaining 8% were in the “quite good” category. The result of the interviews showed that the teachers of MIN (elementary school) already understood the importance of learning science with practical methods, but the inadequate facilities and infrastructure caused practicum  in science teaching to be rarely carried out.

This study aims to develop integrated science teaching materials on the theme "Electricity in Living Creatures" by using the Four Step Teaching Material Development Method (4STMD) which includes the Selection, Structuring, Categorization and Reduction of Dactic stages. This research uses Research and Development (R & D) methods. The subject of this study is all science teaching materials on the theme of electricity in living things studied using the 4STMD method. The data in this study were captured by using various types of instruments that were rationally validated (logical) and empirical (empirical) by experts at each stage of development. Data from expert validation were analyzed using CVR and CVI and percentage analysis. The opinions of students regarding the instructional materials developed and the feasibility of the developed teaching materials were collected using questionnaires. As a development evaluation material in the development of teaching materials, the effectiveness of instructional materials on the thinking ability of knowledge integration in students is also tested. As a comparison, also tested the effectiveness of other teaching materials. The effectiveness test results show that students who use teaching materials developed using the 4STMD method have a higher score (65) compared to students who use other teaching materials (60).

The aim of this study was to develop science teaching material that feature Science, Environment, Technology, and Society (SETS) vision which covers some criteria namely effective. The study employed Research and Development (R&D) design. The R&D four steps were simplified in to three steps, those were define, design, and develop. The subject of this study was fourth grade Elementary School of SDN Kalibanteng Kidul 03. The techniques of data collections were interview, test, observation, and questionnaire. In analyzing data, the study used descriptive qualitative and quantitative. The result of the developed printed material was effective: 1). The result of study, 2). Increasing the result of study 3). Teacher’s activity, 4). and Student’s activity. Based on the result of this study the learning material has reflected the SETS vision and approach. As such, the science teaching material developed has been justified as effective. Therefore it can be used for extended study to produce a much better product as the supplement for learning science in the competency of natural resources.

Little is known about the temporal expression of extracellular matrix components (ECM) and its receptors during development of the heart. Recent reports have shown that ECM components undergo both qualitative and quantitative changes during development, and it is believed that ECM components are important in the regulation of cell migration and cell:cell and cell:ECM recognition and adhesion.Integrins are transmembrane glycoproteins which bind several ECM components on their external face and cytoskeletal elements on the cytoplasmic face. Laminin is a basement membrane component which has been recognized as an important site for cell adhesion. Both the integrins and laminin are expressed early in development and continue to be expressed in the adult heart. With their documented roles in cell recognition, and cell:cell and cell:ECM migration and adhesion these proteins appear to be important components in development of the heart, and their temporal expression may play a pivotal role in morphogenesis and myofibrillogenesis of the heart.

Data Result

Inorganic particulate material of diverse types is present in the ambient and occupational environment, and exposure to such materials is a well recognized cause of some lung disease. To investigate the interaction of inhaled inorganic particulates with the lung it is necessary to obtain quantitative information on the particulate burden of lung tissue in a wide variety of situations. The vast majority of diagnostic and experimental tissue samples (biopsies and autopsies) are fixed with formaldehyde solutions, dehydrated with organic solvents and embedded in paraffin wax. Over the past 16 years, I have attempted to obtain maximal analytical use of such tissue with minimal preparative steps. Unique diagnostic and research data result from both qualitative and quantitative analyses of sections. Most of the data has been related to inhaled inorganic particulates in lungs, but the basic methods are applicable to any tissues. The preparations are primarily designed for SEM use, but they are stable for storage and transport to other laboratories and several other instruments (e.g., for SIMS techniques).
