There is no doubt that science -and, therefore, science education- is central to the lives of all (NGSS, 2013). This manuscript focuses on ideas in astronomy that are at the foundation of elementary students' understanding of the discipline: the apparent motion of the sun explaining the day / night cycle on Earth. According to prior research demonstrating that neither children nor adults hold a scientific understanding of the big ideas of astronomy (NRC, 1996), understanding of concepts may base students' progress towards more advanced understanding in the domain of astronomy. We have analyzed the logic of the domain and synthesized prior research assessing children's spatial representation from an earth- and a space based perspective to develop a set of learning trajectories that describe how students' initial ideas about apparent celestial motion as they take school science can be build upon. In this study elementary students' representations were compared by their resident context including urban and rural. This study may present a first look at the use of a learning progression framework in analyzing the structure of astronomy education. We discuss how this work may eventually lead towards the development and empirical testing of how children learn to describe and explain apparent patterns of celestial motion.

The study aims to investigate the meaning of the rurality in traditional three-verse Korean poem written by Sadaebu(사대부). We will discuss integration method for Rural and rurality. Rurality is not physical truth, but personal and subjective thing. The meaning of the rurality produce socially. So, the concept of the Rurality can be interpreted in many ways. Sadaebu in the Joseon period put emphasis on rural as a object of a self-discipline and govern. They compose a poem from rural life. There are various meaning related to rurality in traditional three-verse Korean poem. The rurality meaning of the Sijo written by Yakcheon and Jonjae can define union between the natural order and poetic narrator. poetic narrators accept theirselves to nature and work willingly. The host of the program must make visitors homesick and gives more energy by Sijo experience program. The most import thing is the identification of the visitor and rural. To accomplish these purpose, It needs visitors can sing a sijo by oneself.

The paper describes the development of a decomposition based multidisciplinary design optimization (MDO) method that coordinates each of disciplinary subspace optimization (DSO). A multidisciplinary design system considered in the present study is decomposed into a number of subspaces based on their own design objective and constraints associated with engineering discipline. The coupled relations among subspaces are identified by interdisciplinary design variables. Each of subsystem level optimization, that is DSO would be performed in parallel, and the system level coordination is determined by the first order optimal sensitivities of subspace objective functions with respect to interdisciplinary design variables. The central of the present work resides on the formulation of system level coordination strategy and its capability in decomposition based MDO. A fluid-structure coupled design problem is explored as a test-bed to support the proposed MDO method.

There has been an explosion of new research and writing about all aspects of the information disciplines. Nevertheless, both academics and practitioners often find it difficult to engage in successful writing strategies. Indeed, writing is hard work, and doing it in a way that leads to publication is an even harder task. Since reading is essential to good writing, the challenges of learning to write are obvious. In this essay, I am drawing on many years of experience in writing and publishing, as well as considerable reading of writers’ memoirs, advice books on writing, literary studies, and other perspectives on the experience of writing in order to offer a set of approaches that can be pursued over a lifetime of scholarship and practice. Writing is a craft or art to be learned, and learning demands paying attention to the audience, having clear objectives, being an avid reader, and possessing the ability to accept and learn from criticism. While information professionals and scholars incessantly write for each other, there are large segments of the public and other disciplines who they ignore. Fortunately, the tools and resources for improving one’s writing are both broad and deep; discipline and realistic strategies are all that are required to improve one’s writing and, ultimately, to achieve success in publishing.

이 연구의 핵심은 가톨릭계 학교에서 생동하는 신앙을 가르치는 종교교육으로 그것은 단순히 종교와 신앙의 전통을 전수하는 그러한 형태의 수업과는 차이가 있다. 지금까지 종교교육의 형태는 가정과 교구에서는 배타적인 형태의 신앙으로 그 교육적 과업이 제한되어 왔다. 반면에 가톨릭 학교의 종교교육은 수학교과 혹은 과학교과와 같이 단지 학문 원리로 종교교육이 수행되어 왔다. 이 논문은 최근 현대 사회 속에서 가톨릭계 학교에서 이루어지는 종교교육의 축소에 주목하면서, 기독교의 신앙과 기독교의 지적 전통이 본래적으로 지니고 있은 본질, 목적, 앎의 양식을 촉진하는 종교교육의 근간을 제안함에 연구의 목적이 있다.

Supercritical water has great potential as a coolant for nuclear reactor. Its use will lead to higher thermal efficiency of Rankine cycle. However, in certain conditions heat transfer may get deteriorated which may lead to undesirable high clad surface temperature. It is necessary to estimate the operating conditions in which heat transfer deterioration (HTD) will take place, so as to establish thermal margins for safe reactor operation. In the present work, the heat flux corresponding to onset of HTD for vertically upward flow of supercritical water in a pipe is obtained over a wide range of system parameters, namely pressure, mass flux, and pipe diameter. This is done by performing large number of simulations using an in-house CFD code, which is especially developed and validated for this purpose. The identification of HTD is based on observance of one or more peak/s in the computed wall temperature profile. The existing correlations for predicting the onset of HTD are compared against the results obtained by present simulations as well as available sets of experimental data. It is found that the prediction accuracy of the correlation proposed by Dongliang et al. is best among the existing correlations.

Purpose: This study was to explore the meaning of masculinity in nursing by investigating how the male qualities are expressed in the culture of nursing wherein men represent a minority group. Methods: Connell's hegemonic masculinity theory (1987, 1995) and qualitative thematic analysis were used to conduct this study in which eight male nurses participated. Braun and Clarke's six stages of thematic analysis (2006) were used for data analysis. Results: The results indicated that masculinity in nursing meant 'soft masculinity' meeting the expectations of the discipline while keeping the male qualities intact. Male nurses were found to suppress their masculinity at earlier stages of their career and to make themselves more accommodating to the profession. However, males re-asserted their masculinity once they became more comfortable with their nursing work. Conclusion: In the field of nursing, masculinity was found to be subjected to stages of attenuating and consolidating which take place in succession. Consolidation of the male qualities was motivated rather unexpectedly by female colleagues. The results confirmed that the issue of gender in nursing is an important factor in recruiting and understanding male nurses in the future.

The essay reflects on the work of Adrian Lapian (1929-2011), an Indonesian scholar of archipelagic/maritime Southeast Asia and its "sea people-sea pirates-sea kings." The essay suggests that Lapian's writing mirrors navigation at sea, and the constant re-orientation and ever-changing, multiple points of view that are part of it. This is contrasted to Foucault's "panopticism" and academic desire for discipline. Taking cue from Lapian's writing and from the present author's experience of seafaring, the essay envisions Southeast Asian studies as a fluid, precarious, disorienting, even nauseating multiplicity of experiences, dialogues, and moving, unstable, and uncertain points of view; a style of learning that is less (neo)colonial, more humble, and closer to experiences in the region, than super-scholarship that imposes universalizing, panoptic standards, theories and methods (typically self-styled as "new") that reduce the particular into a specimen of the general, a cell in the Panopticon. The essay concludes with reflections on certain learning initiatives/traditions at the National University of Singapore, including seafaring voyages-experiences, encounters, and conversations that make students and scholars alike to move and see differently, to be touched, blown away, rocked, swayed, disoriented, swallowed, transformed, and feel anew their places, roots, bonds, distances, fears, blindness, powerlessness.
