Minutes of the state council are the highest level records which can show the overall decision making process at the state level. The purpose of this study is to suggest the methodology for designing historical contents based on relational structure of minutes of state council and records of ministries in the period of Rhee Regime. The methodology has three steps; first, it suggests directions of DB design that represent the basic information and agenda of the state councils through the period of Rhee Regime. Second, it proposes subject classification scheme for major policy matters in the period. to which each agenda will be assigned and related ministries' records will be linked. Third, it suggests the basic structure and procedures to develop the historical contents on each subject matter based on the minutes and relational records of ministries.

In the industrial manufacturing sector, quality control is pivotal for minimizing defect rates; inadequate management can result in additional costs and production delays. This study underscores the significance of detecting texture defects in manufactured goods and proposes a more precise defect detection technique. While the DFR(Deep Feature Reconstruction) model adopted an approach based on feature map amalgamation and reconstruction, it had inherent limitations. Consequently, we incorporated a new loss function using statistical methodologies, integrated a skip connection structure, and conducted parameter tuning to overcome constraints. When this enhanced model was applied to the texture category of the MVTec-AD dataset, it recorded a 2.3% higher Defect Segmentation AUC compared to previous methods, and the overall defect detection performance was improved. These findings attest to the significant contribution of the proposed method in defect detection through the reconstruction of feature map combinations.

Science practice is a process of establishing new relationships with 'foreign things' such as learning objects or tools for observation and measurement. Since the practice of science in major subjects has been increasingly emphasized, we sought to understand the meaning co-created by students and numerous materials who have experienced astronomical observation as a Deleuzian experience of "becoming". We collected activity logs and photographic data written by 17 students participating in astronomical observation activities at "A" High School, and conducted in-depth interviews with the students. We assessed the collected data by reconstructing a situation analysis. The main research results include the students' existential-epistemological 'becoming' process: 1) discovering newness through repetition, 2) becoming an 'explanation machine' to convey the affect of astronomical observation activities, 3) breaking out of a stabilized territory, and crossing a threshold. Based on the results, we suggested the need for follow-up research on the practices and new experimental approaches of teachers in earth science education.

Recently, artificial intelligence (AI) technology has shown potential clinical utility in a wide range of MRI fields. In particular, AI models for improving the efficiency of the image acquisition process and the quality of reconstructed images are being actively developed by the MR research community. AI is expected to further reduce acquisition times in various MRI protocols used in clinical practice when compared to current parallel imaging techniques. Additionally, AI can help with tasks such as planning, parameter optimization, artifact reduction, and quality assessment. Furthermore, AI is being actively applied to automate MR image analysis such as image registration, segmentation, and object detection. For this reason, it is important to consider the effects of protocols or devices in MR image analysis. In this review article, we briefly introduced issues related to AI application of MR image acquisition and reconstruction.

It is very difficult to form a desired complex sound field at a designated region precisely as an application of acoustic arrays, which is one of important objects of array systems. To solve the problem, a filter design method was suggested, which employed the concept of an inverse method using the acoustical holography based on the boundary element method. In the acoustical holography used for the source identification, the measured field data are employed to reconstruct the vibro-acoustic parameters on the source surface. In the analogous problem of source array design, the desired field data at some specific points in the sound field was set as constraints and the volume velocity at the surface points of the source plane became the source signal to satisfy the desired sound field. In the filter design, the constraints for the desired sound field are set, first. The array source and given space are modelled by the boundary elements. Then, the desired source parameters are inversely calculated in a way similar to the holographic source identification method. As a test example, a target field comprised of a quiet region and a plane wave propagation region was simultaneously realized by using the array with 16 loudspeakers.

This study aimed to analyze the learning contents related to biotechnology in life science II and general engineering based on the 2015 revised national curriculum and discuss pedagogical implications for biotechnology education. The main findings were as follows: First, while the learning topics of life science II focused on the ethical aspects related to biotechnology, the learning topics of general engineering focused on the industrial aspects of biotechnology. Second, there were types of overlapping biotechnologies in the life science II textbooks and general engineering textbooks. However, the life science II textbooks provided more scientific and professional descriptions of biotechnology principles than the general engineering textbooks. Also, the life science II textbooks provided more specific overall explanations than the general engineering textbooks. There was a lack of ethical considerations concerning biotechnology in the general engineering textbooks. These findings imply that it is necessary to reorganize biotechnology content based on each school's curriculum and student characteristics.

Our experience with Internet-based scientific collaboratories indicates that they need to be user-extensible, allow users to add tools and objects dynamically to workspaces, per mit users to move work dynamically between private and shared workspaces, and be easily accessible on the Internet. We present the software architecture of a development environment, called Collaboratory Builder's Environment(CBE), for building collaboratories to meet such needs. CBE provides user extensibility by allowing a collaboratory to be constructed as a collection of collaborative applets. To support dynamic reconfiguration of shared workspaces, CBE uses the metaphor of room that can contain applets, users, and arbitrary data objects. Rooms can be used not only for synchronous collaboration but also for asynchronous collaboration by supporting persistence. For the access over the Internet room participants are given different roles with appropriate access rights. A prototype of the model has been implemented in Java and can be run from a Java-enabled Web browser. The implemented system had been used by 95 users including 79 space scientists around the world in a scientific campaign that ran for 4 days. The usage evaluation of the campaign is also presented.

This study examines scale issues in the contemporary feminist migration literature. Scale appears as important, yet poorly understood concept in this field of study. The increasing attention to the feminization of migration requires not only gendered, but also scalar-sensitive approaches. Feminists criticize the conventional approach to the migration as a gender-blind approach that privileges national scale around which migration processes are organized. Claiming multiscalar and interscalar analyses, they propose investigations ranging from macro to micro processes which include globalized gendered division of labor, transnational family networks, and reproduction which takes place in and through the bodies and homes of migrant women. The migrant women, the major actors in recent transnational migration, cross various borders: the national boundaries and the public and private divides, in particular. This crossover can unsettle patriarchal gender relations which have been established based on the physical and symbolic division of nation-states and public/private spheres. Blurring these divisions accompanies social construction of various scales. The transnational family networks of migrant women, for example, show the construction of a transnational scale by migrant women as well as globalization from below. This paper points out misunderstandings of scale in the feminist migration literature and attempts to fill the gaps by introducing the meanings and implications of scales developed mostly by feminist geographers. In so doing, it promotes the interdisciplinary communication.

The stamp commemorating the inauguration of a president is the smallest historical symbol that contains a nation's vision and wishes of the times. The stamp itself is just a collection of images but contains the meaning of the highest leader's perceived image at the time through their face and a symbol. This paper regarded presidential inauguration commemorative stamps in the context of advertisement or promotional materials to structurally analyze the images of the political leaders embedded in stamps utilizing 'semiology' theory, which is considered to be a useful method of advertisement. In accordance with social and cultural changes, the 2000s, when the changes in the presidential inauguration stamp was most distinctively noticeable, was set as the time frame. Only the presidential inauguration commemorative stamps of Moo-hyun Roh, Myung-bak Lee, Geun-hye Park, and Jae-in Moon were selected for this study. In order to interpret the image, a semiotic structure was applied to reconstruct the meaning of the image of the political leaders. Since this can lead to subjective judgment in image analysis, it attempted to find the truth through comprehensive interpretation and approach it from the social and cultural contexts, not a static approach. In this paper, the images of the Korean political leaders in the 2000s shown on stamps are no longer influenced by traditional political factors such as political parties, political ideologies, and regional origins due to the evolution of democracy. This study derives the characteristics of the images of independent and characteristic leaders centered on a person according to the situations and social phenomena of the times.

Transmedia has become a significant theme in the media studies sector and an academic discourse itself since its wide diffusion through Henry Jenkins' seminar book Convergence Culture. The aim of this essay is to examine the authentic intention of the proposer to understand its profound meaning and value in the research discourse. Firstly, Transmedia has originated as a part of the convergence culture research context, which is an identical approach in the 'active audience' research tradition. Thus, a history of the research in terms of Birmingham Cultural Studies tradition and its implication is scrutinized. Secondly, in respect of Pierre Levy's 'collective intelligence' which made significant influence on the making of the Convergence Culture and Transmedia Storytelling, the meaing of the transmedia discourse is studied. Thirdly and finally, the implication of this concept as a critical theory or Critique in the Cultural Studies tradition, which has highlighted the importance of the revelation of the binary oppositions and structures of dominance/resistance, with the interpretation of the role of the collective intelligence idea in the transmedia discourse, is studied.
