The types of inquiry activities included in Life Science II textbooks under the 2015 revised science curriculum were extracted and compared with those of six major and five different publishing companies. The fact that the number of investigation discussions and presentations (IP) increased and the expressions (EX) were included in each unit was interpreted as sufficient to transform the classroom instruction in the 2015 revised science curriculum into student-centered activities. The type of inquiry activities in student-centered activities such as experiment observation, simulation activities, investigation discussions, and presentations accounted for about 41% more than the 27% of 2009 revised science curriculum. However, since data interpretation type is still the largest, it is necessary to reduce the types of data interpretation and to increase the number of types of simulation activities and expressions in order to expand students' creativity and thinking ability when textbook development is needed in the future. In addition to the development of biotechnology, teachers need to reconstruct diverse science materials for each textbook and then use them for students to induce balanced thinking, and try to expand expressive power, creativity, logic, and critical thinking skills.

Grotesque, which has often emerged as a breakthrough in Western art to protest rational and classical pure beauty, is often seen in modern art. Grotesque, along with the concept of pendulum, appears in infinitely expanded forms across cultures, arts, and society. In particular, transformed body images through deformatization and deformatization of the body are interpreted as strong rejections that seek to break away from formalized beauty. The main purpose of this study is how the body reproduced through body deformation, distortion, and bonding in Dimitris Papaioannou's work can be interpreted within the grotesque category. To this end, he examines the Grotesque discourse and modern meaning underlying the interpretation of the work and identifies how the fragmented and expanding body, which is currently actively discussed in the dance world, has an interaction with Grotesque. It selects , , , and , which are the main attributes of the grotesque, focus on conflicting familiarity, life, hatred, and beauty. Based on this, we would like to confirm that in contemporary dance, the reconstructed body reveals concealed things rather than expressing an unrealistic fictional world, and seeks new possibilities beyond boundaries as well as reconsider existing aesthetic views.

Die Gegenwart steht den Tatsachen der Gewalt gegenüber. Wesentlich destruktive Techniken können den kollektiven Tod des Menschen als Gattung produzieren. Die Destruktivität dieser Techniken ist durch Skeptizismus geistesgeschichtlich gerechtfertigt. Ebelings Fundamentalpragmatik ist Reflexionstheorie der widerstandsfähigen Vernunft, welche einer Sozialisierung derjenigen Gewalt widersteht, die in einer gegenwärtigen Aussicht auf universale Selbstdestruktion des Menschen Tod produziert. Selbstbewußtsein (Apperzeption) ist bei Kant Selbstbewußtsein in Gegenstandsbewußtsein. Mit kritischer Auslegung von Kant zeigt Heidegger endlich, daß der Tod der Selbstbeziehung des konkreten Daseins als des In-der-Welt-seins gehört. Aber seine existenziale Analytik berücksichtigt nur individuelles Dasein zum Tode und vernachlässigt die Allgemeinheit des menschlichen Todes bzw. die dem allgemeinen Untergang widerstehende Vernunft. Apel kritisiert ein solipsistisches Erbe von Kants Bewußtseinsphilosophie und präsentiert ein Argument der Letztbegründung zur Überwindung des Skeptizismus. Aber seine Transzendentalpragmatik vernachlässigt die Endlichkeit des menschen und zeigt ein Defizit der fundamentalpragmatischen Vereinigung der Vernunft und des Todes. Aufgrund des gegenwärtigen Todesbewußtseins, das Heideggers Todesdeutung transformiert, rekonstruiert Ebelings Existentialpragmatik Heideggers Dasein zu Existenzsubjekt. Seine Fundamentalpragmatik vollzieht diejenige Erstbegründung, die zwischen der existentialpragmatischen Endbegründung des Todes und der transzendentalpragmatischen Letztbegründung vermittelt, und damit bestimmt sie Vernunft als Widerstandsbewußtsein (das bewußte Sein) gegen den Tod. Also ist sie neue transzendentalphilosophische Bewußtseinsphilosophie, die mit der neuen Selbstbestimmung der Vernunft entwickelt wird.

Synchrotron radiation (SR) has several advantages over convetional x-rays, including its phase, collimation, and high flux. A synchrotron radiation beamline 5C1 at Pohang Light Source (PLS) was recently built for imaging applications. We have shown that a SR imaging system is useful in imaging microscopic structures. SR with broad-band energy spectrum were adjusted to an object by Si wafers and their energy were approximately ranging from 6 keV to 30 keV. SR were passed through an object and finally transformed into visible lights by CdWO$_4$ scintillator screen. The visible lights which were reflected at an angle of 90 degrees by gold plated mirror were detected by a CCD camera and the image data were acquired using image acquisition system. A high-resolution phantom, capacitor, adult tooth, child tooth, cancerous breast tissue, and mouse lumbar vertebra were imaged with SR imaging system. The Objects were rotated within the field of view of the CCD detector, and their projection image data were obtained at 250 steps over 180 degrees rotation. Image reconstructions were carried out in a PC by using IDLTM(Research systems, Inc., US) program. The spatial resolution of the images acquired by the SR imaging system was measured with a high-resolution chart manufactured for several micrometer resolution. The specimens were also imaged with conventional x-ray radiography system to compare the image quality of radiography obtained with the SR imaging system. The results showed more structural details and high contrast images with SR imaging system than conventional x-ray radiography system. The SR imaging system may have a potential for imaging in biological researches, material applications, and clinical radiography.

This paper presents an integrated optimal design technique of a hybrid structure-damper system for improving the seismic performance of the structure. The proposed technique corresponds to the optimal distribution of the stiffness and dampers. The multi-objective optimization technique is introduced to deal with the optimal design problem of the hybrid system, which is reformulated into the multi-objective optimization problem with a constraint of target reliability in an efficient manner. An illustrative example shows that the proposed technique can provide a set of Pareto optimal solutions embracing the solutions obtained by the conventional sequential design method and single-objective optimization method based on weighted summation scheme. Based on the stiffness and damping capacities, three representative designs are selected among the Pareto optimal solutions and their seismic performances are investigated through the parametric studies on the dynamic characteristics of the seismic events. The comparative results demonstrate that the proposed approach can be efficiently applied to the optimal design problem for improving the seismic performance of the structure.

Today computer education puts an emphasis on algorithm education. There are little researches about how to express the given problem in algorithm and how to interpret the expressed algorithm. In this study play-based learning methods dealing with flow chart which is one of the expressing tools of algorithm are developed for lower graders of elementary school. Then we diagnosed the learning possibility of the tool after applying the methods in a classroom environment. There are four types of learning game activities; sequential play, selective play, repetitive play and puzzle play. Puzzle play is a game that students need to reconstruct the learned content to a real flow chart by using flow chart cards. The result of an achievement test after teaching students flow chart showed that the group who took the play-based lesson got their average score with about 7.5% higher than the group who took the ICT-based lesson. Both the groups got their average scroe of more than 9 out of 10 after the lesson. This result shows that flow chart lessons are adaptable for the lower graders of elementary school. It also shows that play-based education can be exceptionally effective.

In hypothesis testing, the interpretation of a statistic obtained from the data analysis relies on a probabilistic distribution of the statistic constructed according to several statistical theories. For instance, the statistical significance of a mean difference between experimental conditions is determined according to a probabilistic distribution of the mean differences (e.g., Student's t) constructed under several theoretical assumptions for population characteristics. The present study explored the logic and advantages of random-resampling approach for analyzing event-related potentials (ERPs) where a hypothesis is tested according to the distribution of empirical statistics that is constructed based on randomly resampled dataset of real measures rather than a theoretical distribution of the statistics. To motivate ERP researchers' understanding of the random-resampling approach, the present study further introduced a specific example of data analyses where a random-permutation procedure was applied according to the random-resampling principle, as well as discussing several cautions ahead of its practical application to ERP data analyses.

This study was carried out to understand the mean of neighbourhood and community organizing model on lived experiences of their organizing and members which had changed. The methods of collecting data was progressed in depth interview. According to study questions and analysis challenges based on theory, we analyzed texts. outcome of study we understood experiences of their organizing and members which had changed. In changing phases of organizational dimension, meaning of 'the discovery of the community problem' was extracted. In this time, organization's members set the goal and experience qualitative and quantitative changes of organization. On the other hand, changing phases of individual dimension were followed, which are 'escaping from locked life', 'reconstruction of self image', 'reconstructing the meaning of both family and self-concept' as well as 'reconstructing the meaning of both neighbourhood and self-concept'. Conclusively, we suggested practical implication, which might increase the effect of neighbourhood and community organizing model.

To detect defect of FPD(flat panel displays) is very difficult due to uneven illumination on FPD panel image. This paper presents a method to detect various types of defects using the approximated image of the uneven illumination by B-spline. To construct a approximated surface, corresponding to uneven illumination background intensity, while reducing random noises and small defect signal, only the lowest smooth subband is used by wavelet decomposition, resulting in reducing the computation time of taking B-spline approximation and enhancing detection accuracy. The approximated image in lowest LL subband is expanded as the same size as original one by wavelet reconstruction, and the difference between original image and reconstructed one becomes a flat image of compensating the uneven illumination background. A simple binary thresholding is then used to separate the defective regions from the subtracted image. Finally, blob analysis as post-processing is carried out to get rid of false defects. For applying in-line system, the wavelet transform by lifting based fast algorithm is implemented to deal with a huge size data such as film and the processing time is highly reduced.

This study introduces a DC resistivity inversion method that incorporates structural and inequality constraints to enhance the resolution of resistivity inversions, and presents sample inversion results with these constraints. In the constrained inversions, a base model is constructed from a layered model through interpretation of other geophysical data. Inversion tests establish that both the structural and inequality constraints produce better resistivity models than the unconstrained inversion. However, the inequality inversion not only reproduces the exact layered structure of the background, it reproduces conductive anomalies at a depth of ~ 10 m when an inexact base model of electrical resistivity is used.
