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.

건설경기 국면에 대한 정확한 판단은 경제활동에 참여하는 주체들의 의사결정에 있어 매우 중요하다. 본 연구에서는 건설경기의 대표적인 변수인 건설수주와 건설투자에 대해 HP 필터와 함께 그간 연구에서 다루지 않은 밴드패스 필터 및 베버리지-넬슨 분해의 방법론을 이용하여 순환변동 분석을 실시하였다. 아울러 GDP 변동과의 관계 비교를 하였다. 의미 있는 분석결과는 다음과 같다. 1976년 1분기부터 2017년 1분기까지 건설수주는 약 7회의 순환변동이 발생한 것으로 분석되었다. 순환변동 상 건설수주는 2015년 2분기에 정점을 기록한 후 하향추세로 전환한 것으로 나타났다. 반면에 건설투자는 같은 기간 약 6회의 순환변동이 발생하였으며, 현재 2012년 3분기 저점 이후 지속적으로 상승하고 있는 것으로 나타났다. 이를 통해 건설수주가 건설투자를 선행한다는 일반적인 속성이 적용되고 있음을 확인할 수 있었다. 또한 건설수주, 건설투자, GDP의 진폭을 비교한 결과, GDP의 진폭이 가장 작고 안정적인 것으로 나타났으며, 건설수주는 그 진폭의 변동성이 가장 큰 것으로 나타났다. 따라서 건설수주는 상대적으로 변동성에 따른 리스크가 큰 변수로 경기 국면에 맞게 정부정책 등으로 조절되어야 할 필요성이 큰 것으로 판단된다.

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.

본 연구에서는 경기변동에 따라 그리고 지역에 따라 달라지는 실업률에 임금이 얼마나 유연하게 반응하는가를 분석한다. 분석의 주된 결과는 다음과 같다. 첫째, 최근의 패널데이터에 근거한 많은 외국의 연구 결과와 마찬가지로 실질임금의 경기순응성(procyclicality)은 매우 크게 추정되었다. 실업률이 1퍼센티지 포인트 하락할 때 실질임금률은 약 3.25% 상승하는 것으로 나타났다. 또한 실질임금의 경기순응성은 여성보다는 남성에게 있어서 더 크게 나타났다. 둘째, Blanchflower and Oswald(1990, 1994, 1995)가 발견한 임금곡선(wage curve)이 우리나라에서도 존재하는 것으로 나타났다. 그러나 그 탄력성의 절대값은 0.1보다는 작게 나타났다. 또한 실질임금률과 지역실업률의 관계는 영구적인 부분(permanent component)에 있어서나 일시적인 부분(transitory element)에 있어서나 부(-)의 상관관계가 있는 것으로 나타났다. 셋째, 본 연구에서 가장 선호하는 모형인 지역실업률과 총실업률을 동시에 포함시킨 임금함수의 추정에서, 임금은 주로 총실업률에 의해 결정되며 지역 실업률의 효과는 미미한 것으로 나타났다. 이는 임금이 일차적으로는 지역노동시장 여건에 의해 결정된다는 Blanchflower and Oswald(1994)의 주장이 적어도 우리나라 노동시장에서는 성립하지 않음을 의미한다. 또한 우리나라에서는 총실업률이든 지역실업률이든 시간지연효과는 거의 없는 것으로 나타났다.

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.
