The purpose of this study was to investigate effects of creative personality education on elementary school students' science-related attitudes and science process skills. The experimental group was composed of 301 students Y Elementary school managing Creativity Personality Model School and the comparative group was composed of 231 students G elementary school in G city, Gyungsangnamdo. Before carrying out the study, both groups took the preliminary examination about their science-related attitudes and science process skills. After three months, the experiment group and the comparison group took the post examinations to compare and analyze the results. The results were as follows. Firstly, the averages of science-related attitudes for whole students, and boy students in experimental group statistically meaningfully higher than that of comparative groups, but made no difference for girl students. Secondary, in the case of science process skills, the averages of science-related attitudes for whole students including boy and girl students in experimental group statistically meaningfully higher than that of comparative groups. In light of these, it was thought that creative personality education positively effected on science-related attitude and science process skills.

Applying the long and distinguished heritage of rhetorical theory to any sacred text, such The Canonical Scripture of Daesoon Jinrihoe, could fill many volumes of many books. This study, then, will provide some suggestive prolegomena for directions rhetorical criticism of the Scripture can take, now and in future research. This study will, further, make necessarily broad strokes in order to familiarize audiences and scholars of new Korean religions, and Eastern thought generally, with Western, both ancient and more modern, modes of rhetorical thought. As rhetorical criticism is increasingly embraced by Western religious scholarship, and as comparative religious studies remain an important dimension of textual scholarship, this article will contribute to both areas by presenting perhaps the first rhetorical-critical approach to the sacred scriptures of Daesoon Jinrihoe. When the new English translation of the Scriptures becomes available in the West, general and scholarly readers will be interested to find parallels and departures with religious and critical traditions with which they are already familiar (in this case, early American Protestant Calvinism). This study will make contributions, then, to the areas of rhetorical-religious criticism, comparative East-West presentations of nature within scriptural contexts, and establishment of grounds for further comparative investigations of Western traditions and Daesoon Jinrihoe.

The purpose of this study is to introduce a modified CPS(Creativity Problem Solving) procedure as a new method for comparative analysis of creative techniques such as SIT(Systematic Inventive Thinking) and Brainstorming(BS) techniques. For this, a new sports game is employed as a case study. The results show that the ideas from SIT are more creative in terms of originality and practicality than those of BS. Several considerations for effective practical use of the proposed method are discussed in this study.

In this article, a comparative study has been made to investigate the scattering behaviour of three layered structure model on torsional surface wave. For such model intermediate layer is taken as fiber reinforced composite, resting over a dry sandy Gibson substratum and underlying by different anelastic media. We consider two distinct mediums for topmost layer. In the first case, topmost layer has been taken as fluid saturated homogeneous porous layer, while in the second case the fluid saturated porous layer has been replaced by a transversely isotropic layer. Simple form expression for the secular equation of torsional surface wave has been worked out in both the cases by executing specific boundary conditions, which comprises Whittaker's function and its derivative, for imminent result that have been elaborated asymptotically. Some special cases have been constituted which are in excellent compliance with recorded literatures. For the sake of comparative study, numerical estimation and graphical illustration have been accomplished to identify the effects of the width ratio of the layers, Biot's gravity parameter, sandy parameter, porosity parameter and other heterogeneity parameters corresponding to the layers and half spaces, horizontal compressive and tensile initial stress on the phase velocity of torsional surface wave.

Extant literature has emphasized the role of citizen participation in creating a successful smart city. However, previous works are lacking in a systematic analysis of the specific mechanisms by which citizen participation makes a positive impact on smart city projects. We attempt to bridge the gap by focusing on the role of the living lab, a citizen-driven mechanism that has used innovative ideas, new technologies, and cooperation with various participants to address local problems. As co-creation is the common ground for smart cities and living labs in terms of citizen participation, we provide a theoretical framework in which the notion of co-creation mediates smart cities and living labs. To examine the living lab's effect of co-creation on smart cities, we conduct a comparative case study of two Northeast Asian cities: Taipei and Busan. We explore (1) the factors behind the different outcomes in these two cities, despite many similarities that might affect smart cities' effectiveness, and (2) the relationship between smart cities and living labs and how to systematically understand the interaction between the two. We find that living labs have played a key role in making Taipei's smart city projects effective and successful, which allows the city to keep showing a high level of performance. In contrast, citizens could not find channels to participate in such projects in Busan. We conclude that the living lab explains why the smart cities in Busan have been less successful than in Taipei.

The core catcher is used as a passive safety system in new generation nuclear power plants to create a space in the containment for the placing and cooling of the molten corium under various severe accidents. This research investigates the role of the core catcher in the VVER-1000 reactor containment system in mitigating the effects of core meltdown under various severe accidents within the context of the Ex-vessel Melt Retention (EVMR) strategy. Hence, a comparison study of three severe accidents is conducted, including Station Black-Out (SBO), SBO combined with the Large Break Loss of Coolant Accident (LB-LOCA), and SBO combined with the Small Break Loss of Coolant Accident (SB-LOCA). Numerical comparative simulations are performed for the aforementioned scenario with and without the EX-vessel core-catcher. The results showed that considering the EX-Vessel core catcher reduces the amount of hydrogen by about 18.2 percent in the case of SBO + LB-LOCA, and hydrogen production decreases by 12.4 percent in the case of SBO + SB-LOCA. Furthermore, in the presence of an EX-Vessel core-catcher, the production of gases such as CO and CO2 for the SBO accident is negligible. It was revealed that the greatest decrease in pressure and temperature of the containment is related to the SBO accident.
