This paper aims to clarify the characteristics of 'the regime 87', the product of democratic transition of Korea in 1987, and its historical evolution. Through the clarification, this paper expects to provide a discoursive basis for reforming the regime 87 and advancing democracy in Korea. For this purpose, this paper seeks to find Korea within the context of macro-historical change of the world. And then this paper tries to analyze the reason and the process of the birth of the regime 87 and its historical evolution.

There is no generally accepted definition of information technology (IT) although this is an important issue in the management information systems (MIS) area. In an effort to address this issue, the evolution of IT is reviewed from a historical perspective. A historical review on IT suggests that its evolution be broken down into three stages in a systematic way. Further, the identification of mainstream research interests at each stage makes a contribution in part to defining IT. Two approaches to defining IT are identified, and limitations of each approach are discussed. Finally, a better way to address these limitations is suggested.

This study traces the origin, evolution, and current state-of-the-art of engineering-oriented water-quality management and modeling. Three attributes of polluted water underlie human concerns for water quality: rubbish (aesthetic impairment), stink (ecosystem impairment), and death (public health impairment). The historical roots of both modern environmental engineering and water-quality modeling are traced to the late nineteenth and early twentieth centuries when European and American engineers worked to control and manage urban wastewater. The subsequent evolution of water-quality modeling can be divided into four stages related to dissolved oxygen (1925-1960), computerization (1960-1970), eutrophication (1970-1977) and toxic substances (1977-1990). Current efforts to integrate these stages into unified holistic frameworks are described. The role of water-quality management and modeling for developing economies is outlined.

The aim of this study is to examine a structure of trousers worn by males in the western world during the 17th and 18th centuries in order to understand the characteristics of evolution in construction. it mainly examined engravings from these era because they provided me fine and detailed portrayals of what it needed to observe. Then, it classified them into models according to each era. it supplemented a flaw of depending on single type of studying material by examining other types of historical materials such as historical paintings and documents for comparative analysis of materials and decorations and previous studies on preserved historical documents to observe the examples of structures of trousers. Secondly, it studied both historical documents and previous studies on the trousers patterns used back in those days, analyzed the characteristics of each designing method by actually draping these patterns, and observed the differences in these completed patterns to understand the characteristics of changes in fashion design skill. As for the changes in length, these patterns show only a slight difference around above and below the knee line. However, the widths of waist, hip, girth and hem were significantly altered over the years to reduce wrinkles and the cutting lines became more refined to make the clothes fit to the body. As a result, a simple but fine patterning technique was born. In particular, new methods in cutting and sewing were invented for detailed parts such as waist, pocket, front and slit.

The overall objective of this lecture will be to present an overview of the evolution of the science of immunotoxicology by highlighting a few key milestones, namely a solid mechanistic foundation and recent applications in a regulatory context. Neither time nor space will allow a discussion of the full extent of the evolution of immunotoxicology from a historical perspective.

Including technical device and general information system, the information-technical(IT) system is defined as the technical system for acquiring, processing, storing and transferring information to a person. This paper presents Knowledge-based Heuristic Evolution Model for creating the advanced information-technical system. This Evolution Model is derived from the historical review on definition of evolution, the research on the architecture of the general IT system, history of IT system, technology innovation theory and multi-case study research. The evolution model is applicable to the conceptual creation of the advanced product in R&D organization requiring development methodologies like rapid-prototyping to develop next generation product. For the detailed theoretical construction and practical application of Evolution Model, the case study research based on action research is performed. the object of the case study is mobile device, especially mobile hand-held phone. Thus, we obtain the Evolution Model for creating the advanced information-technical system.

This study traces the evolution of the compilation of foreign relations of the United States series and analyzes its archival issues from its historical development. The study examines the purposes of publishing the compilations of the diplomatic documents, an issue of making a balance between secrecy for national security and accountability of diplomacy, neutrality in compiling historical materials, and methods and principles of the compilation. To analyze these records issues, the study examines the contents and contexts of the compilation, historical evolution of the compilation, and the political and records issues of the compilation in the U.S. political history. The declassification issue for the historical compilation was also examined because the issue was a major obstacle to the timely publication of FRUS.

Recent studies of science and technology "in-the-making" revealed that the process of designing material artifacts is not a straightforward application of prior images or theories by one (or more) person(s) isolated from his or her (their) environment. Rather, designing is a process contingent on the social and material setting for both engineering designers and students. Over the past decade, designing technological artifacts has emerged as an important learning environment in science classrooms. Through the analyses of a large database concerning an innovative simple machines curriculum for sixth-and seventh-grade students, we accumulated valid evidence for the nature of the designing process and science learning through it. In this paper, we show that design actions intertwine with the transformation of the objectified raw materials and artifact, the designer collective, and the mediating tools enabling that transformation, which constitute the elements of an activity from the perspective of cultural-historical activity theory. We conceptualize the continuous change of relation between material artifacts, designers, and tools throughout the design activity as co-evolution. Two episodes were selected to exemplify synchronic and diachronic change of relations inherent in co-evolving activity system. Finally, we discuss the implications of co-evolution during design activity for science learning.

In this paper, we explore the historical development and revolutionary impact of music in mass media across various forms, including radio, television, film, and digital platforms. The evolution of music in mass media reflects significant technological and cultural shifts over the past century. From the early days of radio to the advent of digital streaming, music has played a crucial role in shaping the types of mass media. Early radio broadcasts in the 1920s relied on live performances and recordings to captivate audiences, establishing music as a central element of media content. The rise of television in the 1950s brought new opportunities for music integration, with theme songs, variety shows, and music videos becoming staples of TV programming. The film industry further revolutionized the use of music, with iconic scores enhancing cinematic storytelling and emotional depth. The digital revolution of the late 20th century introduced new formats and services, expanding access to music and transforming consumption patterns. Recently, streaming platforms and social media allow for personalized music experiences and direct artist-fan interactions. Through an analysis of technological advancements, this study highlights the integral role of music in enhancing narrative, evoking emotions, and creating cultural identities. We present our understanding of this evolution to provide insights into future trends and potential innovations in the integration of music with mass media, including the use of artificial intelligence and virtual reality to create immersive auditory experiences.
