This paper analyzed historical changes in early childhood curriculums from the 19th century to the present. The early childhood curriculum model of the past was based on a modernistic perspective characterized by science, rationality, objectivity, absolutism, and universality. It had been developed in terms of early human resource development to maximize efficiency and rationality for the future. In recent years, however, change occurred in the paradigm of education with the application of phenomenology, analytics, and postmodernism. Newer models for early childhood curriculum include the Reggio Emilia and Developmentally Appropriate Practice, which constitute the current mainstream of early childhood curriculum.

In the early 20th century, Walter Benjamin analyzed the changes in the value of traditional art forms under the industrial era and the changes in the aesthetic attitude of the masses. A century later, in the contemporary multi-art world, the traditional medium of shelf painting is once again experiencing a similar situation as the last century. Emerging technology display modes such as digital virtual reality and digital immersive experience can achieve digital reproduction of paintings on shelves and reach a certain level of performance, which once again shocks the public's aesthetic perception. This paper attempts to illustrate the outstanding characteristics of the new art form after digital reconstruction by exploring the transformation and sublimation of digital technology to shelf painting. We predict that art research on future reality and augmented reality according to the artificial intelligence era will be conducted in depth in the future.

As recently the interest in the future industry grows high, the demand for forecasting the future shape of science and technology, especially exploring 'weak signals' of changes in science and technology, increases as well. The 'weak signals' means that currently they are uncertain and abnormal signals, but are preliminary signals which might lead future changes. Accordingly they can provide important clues to the future forecast. The study of 'weak signals' has its significance in providing important clues to the projection of the future technology earlier. As it has not a long history from its concept to exploration methods to utilization, more intensive study is required. Exploring 'weak signals' has been conducted mainly through the information analysis by experts with a high level of intelligence and sense. However, such an analysis is difficult and broad in scope, and furthermore the interpretation of analysis results is very limited, relying primarily on the decision of experts themselves. The purpose of this study is to provide a more objectified way to support these expert-based tasks. It derives quantitative results from non-structured article information and provides a logical basis for detecting the signals based on the results.

Kelp forests and the many vital ecosystem services they provide are threatened as the severity of climate change and other anthropogenic stressors continues to mount. Particularly in the North Pacific, sea surface temperature is warming and glacial melt is decreasing salinity. This study explored the resiliency of early life-history stages of these foundation species through a factorial laboratory experiment. The effects of rising sea surface temperature under low salinity conditions on kelp spore settlement and initial gametophyte growth in Eualaria fistulosa, Nereocystis luetkeana, and Saccharina latissima were investigated. Decreased settlement and growth were observed in these species at elevated temperatures and at low salinity. Eualaria fistulosa spores and gametophytes were the most negatively impacted, compared to the more widely distributed N. luetkeana and S. latissima. These results suggest that N. luetkeana and S. latissima could potentially outperform E. fistulosa under projected conditions. However, despite decreased performance among all species, our findings indicate that these species are largely resilient to temperature changes when exposed to a low salinity, even when the temperature changes are immediate and extreme. By exploring how early life-history stages of several key kelp species are impacted by dual stressors, this research enhances our understanding of how kelp forests will respond to projected and extreme changes in temperature when already stressed by low salinity.

Available data on the recent global financial crisis (GFC) show that it lasted between the second quarter (Q2) of 2007 and the fourth quarter (Q4) of 2009. Australia is one of the first economies to fully recover from this crisis. This study explorles the role played by the Australian construction industry in stimulating economic growth during the recession. In order to investigate the macro-variability trend during the financial crisis, data were collected and analysed relating to the quarterly GDP of Australia and selected countries between Q1 2000 and Q4 2009. Specifically, changes in the construction industry's GDP were compared with aggregate GDP changes in Australian economy and similar indices in the 'Group of 7' (G7) countries and Organisation for Economic Co-operation and Development (OECD) countries. Moreover, specific attention was focused on Germany, France, Japan, United States of America (USA) and United Kingdom (UK). Graphical and Pearson's correlation methods were used to analyse the relationships between changes in construction GDP and Australia's overall economic growth during the recession. In addition, an attempt was made to develop a regression model for predicting economic growth during the recent recession using changes in gross fixed capital formation (GFCF), changes in construction GDP and the impact of these changes on national economy. Analysis shows a slight contraction in construction activities during the crisis; however construction triggered significant growth in the economy during the crisis period and afterwards. This appears to be the major difference between Australia and other major economies that have experienced a longer recession.

This study aims to present implications to the basic directions according to organization's own objectives, roles, physiology and changes, etc for private security being activated. The change in organization can lead to foster the foundation for coping with sharp social environmental changes. The fundamental factors leading organizational changes should include intentional, planned and future-oriented activities. This is because organizational changes can be achieved by organizational learning. Besides, organizational learning is indeed important in terms of improvement in business methods and security services, but it should be also much more examined than in any other organization, since business particularity lies in getting in most sensitive contact with customers on the spot. Therefore, this study aims to propose the developmental directions of organizational learning by positively exploring the basic learning directions according to the influences of organizational learning, focusing the organizational efficientization strategies coping with environmental changes on the organizational learning.

Gobiids are hyperdiverse compared with other teleost groups, with about 2,000 species occurring in marine, freshwater, and blackish habitats, and they show a remarkable variety of morphologies and ecology. Testing the effectiveness of DNA barcodes on species that have emerged as a result of radiation remains a major challenge in evolutionary biology. Here, we used the cytochrome c oxidase subunit 1 (COI) sequences from 144 species of gobies and related species to evaluate the performance of distance-based DNA barcoding and to conduct a phylogenetic analysis. The average intra-genus genetic distance was considerably higher than that obtained in previous studies. Additionally, the interspecific divergence at higher taxonomic levels was not significantly different from that at the intragenus level, suggesting that congeneric gobies possess substantial interspecific sequence divergence in their COI gene. However, levels of intragenus divergence varied greatly among genera, and we do not provide sufficient evidence for using COI for cryptic species delimitation. Significantly more nucleotide changes were observed at the third codon position than that at the first and the second codons, revealing that extensive variation in COI reflects synonymous changes and little protein level variation. Despite clear signatures in several genera, the COI sequences did resolve genealogical relationships in the phylogenetic analysis well. Our results support the validity of COI barcoding for gobiid species identification, but the utilization of more gene regions will assist to offer a more robust gobiid species phylogeny.

Design is one of diverse human communication activities. Development of technologies has led to execution of more active design communication functions, stirring social and cultural changes. The concept of design communication has become stronger by overcoming the limitations of verbal communication and expanding the methods of communication. These social changes are highlighted In the design of modern space. Even though communication in interior design activities is so important, detailed studies on communication of each entity are still very insufficient. Design communication refers to tools and activities for overall communications in the design process. In design activities, relevant communication is indispensible. Therefore, studies on practical communication methods are essential for accurate communication of content that has to be shared in the results or in the process of obtaining the results, rather than only focusing on the future techniques and functions of design. In other words, improving the efficiency of interior design communication requires establishing a communication relationship structure of each entity, which calls for proper expression methods depending on each entity. Therefore, this study is aimed at exploring efficient expression methods in line with the relationship structure of each entity in the interior design process.
