The first demographic transition refers to the historical decline in mortality and fertility, as shown from the 18th Century in several European populations, and continuing present in most developing countries. The end point of the first demographic transition(FDT) was supposed to be a stationary and stable population corresponding with replacement fertility and zero population growth. In addition, households in all parts of the world would converge toward the nuclear and conjugal types, composed of married couples and their offspring. The second demographic transition(SDT), on the other hand, sees no such equilibrium as the end-point. Rather, new developments bring sub-replacement fertility, a multitude of living arrangements other than marriage, and the disconnection between marriage and procreation. Populations would face declining sizes if not complemented by new migrants. Over the last decades birth rates have been on the decline in all countries of the world, and it is estimated that already more than half of he world's population has below replacement level fertility. Measured in terms of the Total Fertility Rate (TFR), currently 34 countries have fertility levels of 1.5 or less. Similarly, Korea has been below lowest-low fertility for eight consecutive years since 2001 and below the replacement level for more than twenty years. In explaining the low fertility in Korea, some researchers explain the low fertility as revenge against a male-dominated society and institution, while others focus the impact of the employment instability. These studies share the basic ideas (spread of individualism, delayed marriage and childbearing, high divorce rate etc.) of a second demographic transition in order to explain the low fertility in Korea.

The study aims to analyze the research trends according to 'characteristics of researchers' in the research papers published in "The Journal of Educational Administration" between last 10 years(2009 to 2018 first half). The study results are as follow. First, in terms of the researcher, more research was done by 'joint' researchers than a 'single' researcher. In addition, the number of studies in which the first author was male was higher than in women. Also, collaborative research between 'professors' and 'graduate students' was actively done. Second, the number of studies to develop and verify theories(or models) has increased. Third, in terms of research methods, more studies tend to utilize 'quantitative research' using advanced statistics and 'qualitative research' through interviews and observations to describe and explain Korea's educational administration phenomenon. Fourth, researchers showed high interest in 'School organization and management;', 'Higher education', 'Education policy and planning'. Fifth, according to each research area, there were some differences in the characteristics of the researchers who conducted the research, the nature of the research, and the research methods used mainly. Based on the results of this study, this study suggested the future trends of educational administration research in the era of the fourth industrial revolution.

The purpose of the present study is to develop and validate an instrument to assess STEM career motivation. We developed 32 items for 7 constructs (i.e. education experience, career value, academic self-efficacy, career self-efficacy, career interest, parents' support, and career motivation) on STEM career motivation based on Social Cognitive Career Theory (SCCT; Lent et al.,1994). 767 first year high school students participated in this study. The items were validated by Messick's framework (1995). In this study, we examined the validity of items in four aspects (i.e. content, substantive, structural and generalizability of validity). Methodologically, we used Rasch analysis, Exploratory factor analysis, confirmative factor analysis based on structural equation modelling. We confirmed that our instrument with 32 items as valid and reliable for measuring the STEM career motivation. In addition, we tested the STEM career motivation model based on SCCT. Our model explained the data well, suggesting that external factors (education experience and parents' support) and cognitive factors (perception of value, self-efficacy and interest) were significantly related to STEM career motivation.

Since the late 20th century, due to the globalization of markets and the rapid developments of information and communication technologies, the world has entered into the age of fierce competition. With their abundant low-cost labor, former communist countries such as China, Russia and East Europe and former low-developed countries such as India and Brazil have received foreign investments from major industrial companies. Thus, there are no other alternatives remained for Korea and OECD countries other than moving the industrial economies to the knowledge based innovation systems. In the knowledge based innovation systems, economic developments and employments of regions and nations depend solely on companies situated in their territories. In this article, after reviewing the current state of technological based innovation small firms in korea, we provide a theoretical framework to promote the level of technology based innovation and entrepreneurship. The theoretical framework for analysis and policy suggestions is based on the Schumpeter's value system model that consist of supply factors, demand factors, and supporting institutions. In order to create more innovative small businesses, we insist on the followings. First, more R&D and innovation activities related with promising new technologies should be performed. Second, more R&D funds for technological innovation small companies should be provided from governments. Third, more M&A transactions and technology transactions should be marketed freely and competitively. Fourth, more business incubating services and venture capital services should be provided. Fifth, entrepreneurship and innovation culture should be popular and institutionized among people.

The objective of this study is to propose and evaluate the BAYES-ESP, which is a dam inflow prediction method based on Ensemble Streamflow Prediction method (ESP) and Bayesian theory. ABCD rainfall-runoff model was used to predict monthly dam inflow. Monthly meteorological data collected from KMA, MOLIT and K-water and dam inflow data collected from K-water were used for the model calibration and verification. To estimate the performance of ABCD model, ESP and BAYES-ESP method, time series analysis and skill score (SS) during 1986~2015 were used. In time series analysis monthly ESP dam inflow prediction values were nearly similar for every years, particularly less accurate in wet and dry years. The proposed BAYES-ESP improved the performance of ESP, especially in wet year. The SS was used for quantitative analysis of monthly mean of observed dam inflows, predicted values from ESP and BAYES-ESP. The results indicated that the SS values of ESP were relatively high in January, February and March but negative values in the other months. It also showed that the BAYES-ESP improved ESP when the values from ESP and observation have a relatively apparent linear relationship. We concluded that the existing ESP method has a limitation to predict dam inflow in Korea due to the seasonality of precipitation pattern and the proposed BAYES-ESP is meaningful for improving dam inflow prediction accuracy of ESP.

As virtual assistants rapidly diffused into the market, the voice shopping market is expected to expand. The purpose of this study is to identify the factors that determine the consumers' intention to adopt voice shopping by using the unified theory of acceptance and use of technology(UTAUT). In this study, we set variables that influence the intention to adoption of voice shopping with performance expectation and effort expectations as the variables of UTAUT and playfulness expectations as an extended variable. In addition, we also include four voice secretary attributes such as response accuracy, compatibility, social presence, and safety in our research model to investigate the source of motivation of voice shopping adoption. The result of this analysis shows that variables such as performance expectation, effort expectation, and amusement expectation have a positive effect on the intention to adoption of voice shopping. With respect to the four voice shopping attributes, compatibility had a positive effect on performance expectancy, effort expectancy, and playfulness expectancy. Social presence has a positive effect on playfulness expectancy. Safety has a positive effect on effort expectancy and playfulness expectancy. On the other hand, response accuracy is not significant for performance expectancy, effort expectancy, and playfulness expectancy. This study reveals the determinants of intention to adopt the new purchasing method called voice shopping, and suggests the important factors for the innovation of commerce business.

It has been frequently pointed out that the established art history with the stylistic and iconographic interpretations and monographic analysis is fallen behind the currency of modern art. Among those who claimed the crisis in the discipline of art history, there is a suggestion that the art historical study should be fostered by other factors in the fields of the humanities. The so called New Art History or 'visual Culture Studies' insists that art history has to be restructured to integrate the broader study of culture and society, and by now, such an opinion is not a novelty at all. One of the most significant yet overlooked elements that induced the new currency of art history is properties of contemporary art that conflict the traditional claim of art historians. Although the idea that art is not purely aesthetic but that it has many other functions has been brought up by the art historians, it was the artists that provoked such a perception. When Arthur C. Danto and Hans Belting proclaimed the End of Art and Art History in the 1980s, the concept of art has been changed radically through the avant-garde tendency of Modernism and a new pluralism of Postmodernism. One dominant concern that strikes art historians is to find a new approach to art, since the traditional method and goal of analysis for past art and past art history seem unavailable. The perplexity arising from the situation is intensified in the field of teaching art, especially for those who teach art history in art school. Basically art history is a pursuit of learning of art in history, and its purpose is to reconcile the present with the past and the future as well. Since Modernism, as it is confusing sometimes because it implies the present state, somehow art became considered 'tradition-less'. It does not mean that a work of art stands aloof from the past attainments, hut modern art imposed itself on a task seeking after the new for its own sake, turning its back on the tradition. And now in the era of Postmodernism, an historians face the requirement to revaluate the whole history of art including modernism. The necessity of art history in art education is indisputable, but methods and contents in the academic courses should he reexamined now. Because artists' concept of history and past art has been altered, and art history as a humanistic discipline can only maintain its identity through incorporation with art itself. Academics teaching art history, or, strictly speaking, past works of art and history, to the student in art school, confront with the need to rethink the object of art history and its meaning to the artists.

Since the third inter-Korean summit, the inter-Korean summit in Pyongyang and the U.S.-North Korea summit in Singapore and Hanoi, denuclearization negotiations are under way that will determine the fate of the Korean Peninsula. However, the negotiations are stalled and some skepticism is expected due to the conflicting U.S.-North Korea stance over the terms of denuclearization. The reason why it is difficult to realize the complete denuclearization of North Korea is that there are a variety of variables such as the traditional security dilemma in Northeast Asia, the hegemonic competition between the U.S. and China, and the formation of a new cold-war system. At a turning point when three inter-Korean summits and three U.S.-North Korea summits were held in the wake of the 2018 PyeongChang Winter Olympics, North Korea's complete denuclearization has become a must-do historical task for Northeast Asia and world peace beyond the Korean Peninsula. In this sense, the inter-Korean summit in Pyongyang is seen as a historic occasion for presenting a new milestone for the denuclearization of North Korea and the development of inter-Korean relations through the 9.19 Pyongyang Joint Declaration and the Military Agreement. Meanwhile, Constructivism, which has become the main paradigm of international political theory, presents the view that ideological variables such as ideology, history and culture define material factors, identity and interests of state actors, and that the structure of international relations can be changed through interaction. In this study, the historical meaning of the 9.19 Pyongyang Declaration, which is now past its first anniversary, was considered from a constructivist perspective. To this end, the development process of constructivism theory and analysis model and the development process of inter-Korean relations were briefly reviewed, and the military implications of the 9.19 Military Agreement were presented.

The aim of this study was to theoretically examine the current status of TV home shopping business entities' expansion of business structure, and then look into TV home shopping business entities' preparation for the future business in their mature period. For this, the investigator examined literature home and abroad and then empirically carried out an experimental sale of household goods by selecting a model TV home shopping business entity. In order to understand current business structure of TV home shopping and increase sales, the investigator has changed price and then induced sales, focusing on the price of household goods. Study findings are as follows: As for the influence of TV home shopping household goods' price upon its sales, because TV home shopping business entities set in advance an efficiency unit-price per broadcast hour and carry out a sales strategy of reaching out the efficiency, they try to keep their sales with discounted price in the real sales setting of TV home shopping. But it is not an exclusive practice. General promotion became a common practice. The price of goods is the same with its life. Continuous discount events lower the reliability of goods and its supplier must bear the result. Overall sales after experiment increases by 13% and the sales efficiency also increases by 9%. Sales amount increases by 9% and a stable sales which is above average is achieved. The number of sales goods keeps 100%.
