The researches on cyclical patterns of R&D investment has a long history in developed economies since the Schumpeterian hypothesis that long-term productivity-enhancing innovative activities increase during recession. But in Korea the cyclical patterns of R&D investment is one of the unexplored academic areas. Unlike theoretical explanation of R&D's cyclical pattern, empirical results has shown that R&D investment is procyclical to business cycles in developed countries. This paper investigates whether Korean R&D investment show procyclical or countercyclical pattern to business cycles. The empirical results show that Korean R&D investment in private area is procyclical to business cycles with statistical significance, which confirms the credit-constraint theory's prediction, while public area's is not sensitive to them. Public R&D investment has long-term investment characteristics and can be utilized to stabilize procyclically-fluctuating private R&D investment.

This paper examines the cyclical fluctuation of 'construction orders' and 'construction investment' using HP filter, Bandpass filter and Beveridge-Nelson decomposition methods. The main results are as follows. As a result of the analysis of the cyclical fluctuation of construction orders, it was analyzed that there were about 7 cyclical fluctuations from 1976 to the first quarter of 2017. Construction orders for cyclical fluctuations peaked in the second quarter of 2015 and turned to a downward trend. On the other hand, construction investment has experienced about 6 cycles of fluctuations during the same period, and it has been rising continuously since the bottom of 3Q12. This is consistent with the general theory that construction orders precede construction investments. In addition, the comparison of the construction orders, construction investment, and GDP amplitude shows that the GDP amplitude is the smallest and stable, and the construction orders have the greatest variation in amplitude. Therefore, construction orders should be adjusted by government policy depending on economic fluctuations.

The concept of style provides a useful structure in history of Art. In aspect of formative art, dress and art work are alike, so style is a useful concept in the historical methodology on dress. The main purpose of this study was to apply the art criticism to the historical methodology on dress. For this purpose, documentary studies about style as a tool of historical research were proceeded. The results were as follows : 1. The concept of style consists of the external form and the internal meaning as double roots. Therefore, it's indispensable that the two asp-ects of style, form and meaning, must to be harmonized to describe the historical phenomena in dress. 2. The change pattern of style in dress is not always predeterminate and regular according to the cyclical theory. From the alternative point of view, the change pattern of style could be to describe the continuous theory proposed by kroeber, Brodsky. The whole change of style is considered "liked solution" by this theory.is theory.

The purpose of this study was to introduce the concepts of experiential learning and the Kolb's model, and to review some applications of experiential learning theory in graduate medical education. The published literature on GME and education for general practitioners applying the experiential theory and the Kolb's model was reviewed. Experience learning defined the cyclical learning process which emphasizes the learners' reflective thinking of the learners' concrete experiences and their active participation in continuous learning actives. Kolb includes this 'cycle of learning' as a central principle in his experiential learning theory. This is typically expressed as a four-stage cycle of learning. Kolb's cycle moves through concrete experience(CE), reflective observation(RO), abstract conceptualization(AC) and active experimentation(AE). Components of continuing education of the adult learner were based on autonomy, context of learning, and competence and performance as educational objectives. Some strategies for graduate medical education were reflective thinking, self-directed learning, morning reporting and feedback with peer review, etc. Opportunities for learning from experience in practical life can be made to enhance reflective thinking and performance of practitioners. Strategies to develop reflective practice among physicians should be explored by further research.

The concept of style including the external form and internal meaning provides a useful structure to clarify the historical phenomenon on dress. The purpose of this study was to explore surrealism related to the external form and internal meaning and the stylistic change of surrealism through 1930 and 1988 according the linked solution proposed by Brodsky. The results were as follows; 1. In terms of double roots including the external form and the internal meaning on the surrealism of dress, first, the external form was founded to be that each objects having symbolic meaning was dislocated from its original place to dress. Second, the aspects of internal meaning intended to represent not rational and external world but irrational as well as to reveal other nature of object or dress itself. 2. The change of surrealistic style on dress was characterised as "linked solution" change theory than cyclical change theory through the historical data from 1930 to 1988 of documentary sources.

This study investigates if the relationships between hemline and macro-economic factors (rGDP, recession, and unemployment) are still applicable as well as analyzes time lags that reflect economic factors on the hemline index using U.S. data. The hemline theory and fashion cyclical theory were applied to propose the relationships studied. The data for the hemline measurements of women's day-wear were obtained from US Vogue spring and fall editions from 1950 to 2014. Data were standardized by dividing the length from shoulder to hemline by the length from the shoulder to ankle. I aggregated 2260 samples and hemline data to create a yearly average. This study used OLS of Stata 13 program to explore the relationship between macro-economic factors and hemline. The main findings were the recession and unemployment influenced hemline length for four years in a positive direction. Furthermore, the effects of previous recession and unemployment on the current hemline were very close to the significant level respectively. This finding supports the hemline theory in that a recessionary economy is related to longer hemlines and hemlines become shorter in flourishing economic periods.

This paper investigates how real wages adjust to regional and cyclical shocks in the Korean labor market. Major findings are as follows. First, like most longitudinal studies in this literature, we find that real wages are strongly procyclical and more procyclical for men than for women. Second, consistent with the theory prediction of efficiency wages, both permanent and transitory components of real wages are negatively correlated with the local unemployment rate. Third, when overall and local unemployment rates compete in a wage equation (our preferred specification), current wages are dominantly affected by the overall rate, and the effect of the local rate is rather small. This rejects the Blanchflower and Oswald's hypothesis that wages are primarily determined by local labor market conditions. Finally, no lagged effects on wages are detected in the overall or local unemployment rate.

Many researchers have studied the process of retail evolution in the United States and in Europe. Although extensively studied(e.g., Agergaard, Olsen & Allpass, 1970; Oren, 1989), used in conceptual work(e.g., Cist, 1968), and applied as foundation in empirical work(e.g., HcNair, 1958), some limitations exist as follows: inability to cover multiple types of retail institutions and limited quantification. The purpose of this study is to build a conceptual framework combining existing retail evolution theories to overcome existing limitations. Data collection and analysis followed a qualitative research design, specifically a grounded theory type of design with a constant comparative analysis method. As a result of the study, a conceptual framework was built by synthesizing aspects of retail evolution theories and showed retail institution types in a change process.

The semiconductor industry is a competitive, complicated and a cyclical sector with a highly dynamic business climate which requires an effective leadership style to operate and succeed. This study explores the important issue of how leadership facilitates employee innovative work behaviors in the semiconductor industry. Based on the assumptions of the ambidextrous leadership theory and social exchange theory, we collected data from 300 workers employed in the semiconductor industry of South Korea. The study investigated (1) the impact of ambidextrous leadership on innovative work behavior, (2) the mediating effects of workers decision-making autonomy and workplace learning in the relationship between ambidextrous leadership and innovative work behavior, (3) the moderating role of resistance to change in the relationship between ambidextrous leadership and workplace learning, and (4) the moderating role of openness to experience in the relationship between ambidextrous leadership and innovative work behavior. SmartPLS 4 and SPSS v24 was used to analyze our data. The study revealed that ambidextrous leadership positively influences workers innovative work behavior. In addition, decision-making autonomy and workplace learning partially mediated the relationship between ambidextrous leadership and innovative work behavior. Moreover, resistance to change was found to be a significant moderator in the relationship between ambidextrous leadership and workplace learning. Based on these findings, we conclude that ambidextrous leadership is very imperative for semiconductor businesses seeking to foster employee innovative work behaviors. Theoretical and practical implications of the study are also discussed.

The major purpose of this paper is to examine two closely related issues. An attempt is made here to examine internationally high land price in Korea from the perspectives of market fundamentals (MF) and bubble theory, respectively. Another theoretical issue, whether land speculation can result in market failure, is also examined. It has been concluded that the primary causes for the rapid increases in land prices in Korea, could be found in the perspective of MF. (1) The financial intermediaries has been controlled by the government since 1960s. Real Interest rates in the commercial banks has been controlled at the level of zero or sometimes negative; scarce financial resources has been rationed by the government. The governmental control of the bands has also resirained the development of securities market. Money, which can not find the appropri opportunity for saving in financial market, moves to land market. (2) Socially created land value, based on rapid economic gorwth and big public investment, has been appropriated mainly by the private: The effective tax rate of land holding tax has been under 0.02 percent; Real Estate Capital Galns Tax has, in fact, affected few persons, mainly because examptions and preferential taxation have been widely permitted. (3) The government has ploaced severe limitations on rural-to-urban land conversion, although the demand for urban uses has repidly grown. All factors above caused the cyclical land speculation. This, in turn, created the myth that land prices will inevitably continue to rise. Based on the myth, the growing bubble in land price has been created. This is the secondary reason for high land price relative to income in Korea. It is also shown that it is possible that speculation in land results in market failure because land is fixed in quantity and can be used for production and speculation purposes simultaneously.
