  • This study investigated student's prior conceptions and evidence evaluation about Light and shadow. One hundred twenty six students were given Explanation-after-choice type Questions to investigate student' prior conceptions and Choicd type Question to identify student's idea about scientific method and characteristics od observation. Forty-four of the 126 students were interviewed to explore student's evidence evaluation. Eighty students (63.5%) thought that the shape of material affected the shape of shadow but the shape of light source did not Only 58.8 precents of all responses were evidence-based responses. Characteristics of evidence affected student's evidence evaluation : student made evidence-based responsed to the accord evidence more frequently than discord evidence. Among evidence-based response to the discord evidence. 35.5% of responses were the case that student felt cognitive conflict or explored other variables by recognizing discord between his/her own ideas and evidence or distort the evidence. Student's idea about characteristics of observation did not affect the evidence evaluation, but student's idea about scientific method affected the evidence evaluation.

  • This article highlights the importance of design in the formation of worldview paradigms in global culture. The research aims to investigate the design development as a part of the culture and its significance in the social development of society and worldview standards. The article uses general scientific methods of cognition, showing the transformation of design in the social and cultural sphere based on scientific and business literature. The research results show the chronology of design development as a factor determining the development of society and its worldview. In particular, the epoch of modernism, classical functionalism, postmodernism, post-industrialism, and digital design show their own particularities of design development. Furthermore, the article reveals the peculiarities of design development and its requirements depending on the development of society, progress, and civilization in general. The question of current and future trends in the development of design as a factor of worldview paradigms in the culture is based on digitalization, globalization, and the formation of design as an independent entity that determines man's place in the world and society.

  • Non-monolithic concrete structural connections are commonly used both in new constructions and retrofitted structures where anchors are used for connections. Often, flaws are present in anchor system due to poor workmanship and deterioration; and methods available to check the quality of the composite system afterward are very limited. In case of presence of flaw, load transfer mechanism inside the anchor system is severely disturbed, and the load carrying capacity drops drastically. This raises the question of safety of the entire structural system. The present study proposes a wave propagation technique to assess the integrity of the anchor system. A chemical anchor (embedded in concrete) composite system comprising of three materials viz., steel (anchor), polymer (adhesive) and concrete (base) is considered for carrying out the wave propagation studies. Piezoelectric transducers (PZTs) affixed to the anchor head is used for actuation and the PZTs affixed to the surrounding concrete surface of the concrete-anchor system are used for sensing the propagated wave through the anchor interface to concrete. Experimentally validated finite element model is used to investigate three types of composite chemical anchor systems. Studies on the influence of geometry, material properties of the medium and their distribution, and the flaw types on the wave signals are carried out. Temporal energy of through time domain differentiation is found as a promising technique for identifying the flaws in the multi-layered composite system. The present study shows a unique procedure for monitoring of inaccessible but crucial locations of structures by using wave signals without baseline information.

  • The aim of this study is to answer the straightforward question of whether the implementation of IC has fueled non-interest incomes of banks or not. By utilizing the data of 26 domestic banks in Vietnam and employing the value-added intellectual coefficient model (VAIC) as the measure of IC efficiency, our empirical evidence manifests that IC plays a vital role in fostering non-interest incomes of banks. When dividing VAIC into different components, we find that structure capital employed (SCE) is the most important component to enhance the expansion of these incomes compared with other components including capital employed efficiency (CEE), human capital efficiency (HCE). These findings remain unchanged through some robustness tests performed. While the main driver of IC and SCE, CEE component becomes a substantial advantage to increase non-interest incomes in large banks. Meanwhile, the degree of impact of SCE is higher in small banks compared with large ones. Overall, this study would provide a deep insight into the role of IC in the transformation into non-interest income activities of banks in an emerging country, and therefore our findings would be useful for both scholars and policy-makers in Vietnam, where has undergone the period of major reforms in banking system.

  • The posthumanism, as it is discussed in several areas of the humanities, calls the modern humanist concept of autonomous subject into question. The scientific psychology has been since its birth as independent discipline at the 19th century a 'posthuman psychology' in the sense that there has been always humanistic approaches to humans as autonomous beings on the one hand, and natural-scientific approaches to humans as determined beings on the other hand. I have argued that the concept of autonomous subject makes still sense as a regulating principle of everyday life of purposive agents and as a conceptual framework for interpreting causal knowledges about humans. And I have argued that culture and cultural education should play an important role in reflecting on the meaning and rationality of sciences and technologies.

  • Few studies have dealt with the question of when Mt. Baekdusan became known as a volcano. Attention has been focused rather on the issue of establishing the boundary between the Joseon Dynasty and the Qing Dynasty than the scientific nature of Baekdusan as a volcano. It is only in the late Joseon Dynasty that Park Jong (1764), who was the scholar of the Gwanbuk region, authored the first travel journal on Mt. Baekdu and described poseok. Due to the scientific curiosity of Westerners on the existence of mysterious snow peak on the border, it was first introduced to the Royal Geographical Society by a British man, H.E.M. James in 1887, who revealed for the first time that Mt. Baekdu is a dead volcano, and that the white color on the top is due to wide-spread pumice. Russian expedition teams including Strel'bitskii (Стрельбицкий, 1894, and Garin (Гарин-Михайловский, 1898), also explored this mountain seeking natural resources and territory of East Asia and the Manchurian region in pursuit of Russian Imperial interests explored and described Baekdusan as a volcano.

  • This study reviewed and discussed the nature of scientific hypothesis described in philosophy, the philosophy of science, science, and science education. In these descriptions, a hypothesis was defined as one of five types: hypothesis as an assumption, hypothesis as a prediction, hypothesis as a tentative explanation, hypothesis as a tentative law, and hypothesis as a tentative causal explanation. Most scholars agreed that a hypothesis is a proposition or a set of propositions proposed as an explanation for an observed situation. In this view, a hypothesis is a possible answer to or an explanation of a question that accounts for all the observed facts. Also, it is a statement that explains why things happen in nature or an explanation for an observation that can be tested. In the five types of hypothesis meanings, a tentative explanation includes a tentative law and a tentative causal explanation. However, tentative laws are not explanation but description which are general statements drawn from specific experiences by way of a process known as induction. A number of studies also have distinguished hypothesis from assumption, tentative explanation, tentative law, and prediction. Therefore, a hypothesis is concluded to be a proposition or a set of propositions proposed as a tentative causal explanation for an observed situation.

  • The purpose of this study is to analysis ERF components patterns of causal questions generated during the observation of biological phenomenon. First, the system that shows pictures causing causal questions based on biological phenomenon (evoked picture system) was developed in a way of cognitive psychology. The ERF patterns of causal questions based on time-series brain processing was observed using MEG. The evoked picture system was developed by R&D method consisting of scientific education experts and researchers. Tasks were classified into animal (A), microbe (M), and plant (P) tasks according to biological species and into interaction (I), all (A), and part (P) based on the interaction between different species. According to the collaboration with MEG team in the hospital of Seoul National University, the paradigm of MEG task was developed. MEG data about the generation of scientific questions in 5 female graduate student were collected. For examining the unique characteristic of causal question, MEG ERF components were analyzed. As a result, total 100 pictures were produced by evoked picture and 4 ERF components, M1(100~130ms), M2(220~280ms), M3(320~390ms), M4(460~520ms). The present study could guide personalized teaching-learning method through the application and development of scientific question learning program.

  • The purposes of this paper are twofold: First, to discuss ways and limits of studying politics scientifically; second, to examine group theories to the study of political science. To answer the first question, I examine philosophy of science, methods of scientific research, and limits of scientific study of politics. As a subject matter itself, political science involves the study of human beings and the discovery of explanations for the political behavior that they exhibit. This discovery of regularities of behavior in politics inevitably requires that human beings act consistently or discoverable manner. I argue that the best way of studying politics as much as possible is to combine traditional and scientific approaches depending upon issues, The second section of this paper will examine one of important middle-range theory of politics; group theories (approaches). Examining this will show strength and limits of studying politics scientifically. The group approaches examine the importance of role that people hold in the political system as well as the relationship between the action of collective group and its impact on the political behavior. Overall, the group approaches tend to deal with individuals in specific societal contexts and with varying distributions of power between the actors. This group approaches are premised on the belief that political activity involves more than just one individual, political activity occurs instead through individual actors in particular settings. I argued that group theories have some explanatory power and descriptive richness, though it has limitations.
