Purpose : The purpose of this study was two-fold: to identify the effect of dental hygienist's self-determination motivation on their job engagement and to analyze the moderating effect of compensation satisfaction that affect the relevance. Methods : Data were collected using a structured self-report questionnaire administered to 260 dental hygienists working in dental hospitals and clinics in Busan, South Korea. These were analyzed using IBM SPSS Statistics version 26.0 and SPSS Process Macro 3.5. A frequency analysis, including the respondents' general characteristics, frequency, percentages, and standard deviations, was performed. A regression analysis was also performed using SPSS Process Macro to verify the moderating effect of compensation satisfaction in the effect of self-determination motivation on job engagement. Results : The self-determination motivation of the dental hygienists had a statistically significant positive effect on their job engagement, which was the dependent variable. Higher intangible compensation satisfaction levels led to a stronger effect of intrinsic motivation but a weaker effect of extrinsic motivation on job engagement. Moreover, higher tangible compensation satisfaction levels strengthened the effect of intrinsic motivation on job engagement. Conclusion : Recently, the demand for oral health care has been increasing, Competition in the dental medical service market warrants, high-quality dental services based on accurate diagnosis and treatment. In this context, dental hygienists' job engagement must be improved. For this purpose, increasing the satisfaction of dental hygienists with self-determination motivation and appropriate compensation is effective. In addition, attention must be paid to the moderating effect of compensation satisfaction on the relationship between intrinsic motivation and job engagement. On the basis of the implications of this study, the results can be used as basic data for improving dental hygienists' welfare system and manpower management.

본 연구는 경영자의 초과보상이 신용등급에 미치는 영향을 분석하는 것이다. 적정수준을 초과하는 경영자의 초과보상의 크기가 클수록 기업의 미래 성과에 부정적인 영향을 미친다는 선행연구에 근거하여 경영자의 초과보상이 신용등급에도 부정적인 영향을 미칠 수 있다고 예상하였다. 이를 확인하기 위하여, 2014년부터 2019년까지 국내 상장비금융기업들을 대상으로 임원의 평균 보상을 통하여 경영자의 초과보상을 측정한 후, 초과보상의 크기가 차기 신용등급에 영향에 대하여 회귀분석하였다. 분석결과, 초과보상이 양(+)의 값을 가질 때, 즉 적정수준을 초과하여 경영자에게 보상이 지급될 때, 경영자 초과보상과 차기 신용등급이 음(-)의 관계로 나타났다. 또한 중소기업 표본에서 초과보상과 신용등급의 음(-)의 상관관계가 있는 것으로 나타났지만 대기업 표본에서는 상관관계가 없는 것으로 나타났다. 본 연구는 초과보상이 기업의 미래 성과에 미치는 부정적인 영향으로 인하여 신용등급에 영향을 주며, 그러한 영향은 대기업 여부에 따라 달라질 수 있다는 결과를 제시함으로써, 경영자의 초과보상이 기업의 성과에 미치는 부정적인 영향에 대하여 시장의 인지 가능성을 확인하였다는 점에서 공헌점이 있다.

This study aims to investigate the direct relationship between ownership structure, earnings manipulation, and organizational performance, and then examine the mediating effect of earnings manipulation in the relationship between ownership structure and organizational performance. This study collected and analyzed secondary data published in financial reports related to all insurance organizations listed in the Jordanian market during the study period (from 2009 until 2018). A panel data analysis was conducted, giving a total of 200 observations. The findings of this study concluded that ownership concentration, foreign ownership, and organization size affect organizational performance proxied by ROA, ROE, and EPS, more specifically, ownership concentration and organization size have a positive effect, whereas foreign ownership has a negative effect. At the same time, board of director ownership, organizational ownership, and CEO compensation did not affect organizational performance. Next, the board of director ownership, ownership concentration, foreign ownership, and CEO compensation affect earnings manipulation separately. In addition, earnings manipulation positively affects organizational performance proxied by ROA, ROE and EPS. This means that the higher the earnings manipulation is, the higher the organizational performance is. Finally, earnings manipulation mediates the relationship between ownership concentration and foreign ownership of ownership structure, and organizational performance.

Purpose: This study investigated the effects of valuation errors on the capital market through the earnings forecasting errors of financial analysts. As a follow-up to Jensen (2005)'s study, which argued of agency cost of overvaluation, it was intended to analyze the effect of valuation errors on the earnings forecasting behavior of financial analysts. We hypothesized that if the manager tried to explain to the market that their firms are overvalued, the analysts' earnings forecasting errors would decrease. Research design, data and methodology: To this end, the analysis period was set from 2011 to 2018 of KOSPI and KOSDAQ-listed markets. For overvaluation, the study methodology of Rhodes-Kropf, Robinson, and Viswanathan (2005) was measured. The earnings forecasting errors of the financial analyst was measured by the accuracy and bias. Results: Empirical analysis shows that the accuracy and bias of analysts' forecasting errors decrease as overvaluation increase. Second, the negative relationship showed no difference, depending on the size of the auditor. Third, the results have not changed sensitively according to the listed market. Conclusions: Our results indicated that the valuation error lowered the financial analyst earnings forecasting errors. Considering that the greater overvaluation, the higher the compensation and reputation of the manager, it can be interpreted that an active explanation of the market can promote the accuracy of the financial analyst's earnings forecasts. This study has the following contributions when compared to prior research. First, the impact of valuation errors on the capital market was analyzed for the domestic capital market. Second, while there has been no research between valuation error and earnings forecasting by financial analysts, the results of the study suggested that valuation errors reduce financial analyst's earnings forecasting errors. Third, valuation error induced lower the earnings forecasting error of the financial analyst. The greater the valuation error, the greater the management's effort to explain the market more actively. Considering that the greater the error in valuation, the higher the compensation and reputation of the manager, it can be interpreted that an active explanation of the market can promote the accuracy of the financial analyst's earnings forecasts.

Group level discriminations are observed in employment relations and other transactions in the form of residential occupational and production segregation and differential treatments. Recent developments in the rational theories of discrimination both on the market level and the non-market level are reviewed in terms of their relative strengths, weaknesses and complementarities. Taste discrimination could remain much suppressed in the market but could effect much chain reaction through various ways of statistical discrimination, price discrimination, human capital investment and segregation. Taste discrimination could also take the more structured form of co-workers' requiring compensation for reduced productivity due to increasing interactions with members of different language and culture in a non-segregative system. If could also be viewed in the framework of brand learning models. Non-market models of discrimination are seen to be an essential part to explain extended modes of discrimination.

The present paper presents a genetic algorithm (GA) to maximize social welfare and perform congestion management by optimally placing and sizing one Thyristor-Controlled Series Capacitor (TCSC) device in a double-sided auction market. Simulation results, with line flow constraints before and after the compensation, are compared through the Sequential Quadratic Programming SQP method, and are used to analyze the effect of TCSC on the congestion levels of modified IEEE 14-bus and 30-bus test systems. Quadratic, smooth and nonsmooth (with sine components due to valve point loading effect) generator cost curves, and quadratic smooth consumer benefit functions are considered. The main aims of the present study are the inclusion of customer benefit in the social welfare maximization and congestion management objective function, the consideration of nonsmooth generator characteristics, and the optimal locating and sizing of the TCSC using real code-based GA to guarantee fast convergence to the best solution.

본 연구는 우리나라에서 근로빈곤을 발생 확대시키는 사회구조적 요인들을 실증하고자 하는 것이 연구목적이다. 1982년부터 2004년까지의 통계청 <도시가계조사> 원자료를 활용했고, 거시경제 환경, 노동시장, 분배제도 등 사회구조적 요인들에 대한 시계열 자료를 이용한 다중회귀분석을 실시했다. 성장론자들의 주장과는 달리 경제성장은 근로빈곤층 규모 변화에 정적인 영향을 미치는 것으로 나타났고, 성장기에는 경제성장의 낙리효과(trickle down effect)가 존재하나 포드주의 이후에는 단절된 것으로 확인됐다. 사회복지지출은 근로빈곤을 완화하는데 효과가 없었다. 최근 미국식 자본주의 모델을 도입한 결과 소득분배가 악화되고 고용의 질이 후퇴하고 근로빈곤이 확대돼 왔고, 제도 간 비정합성이 표출돼 사회경제적 지속성에 의문이 제기되고 있는 만큼, 한국형 사회적 시장경제모델로의 전환을 모색해 안정적이고 지속가능한 모델을 구현해야 한다.

문화산업은 인간의 창작성을 활용하여 고부가가치를 창출할 수 있다는 점에서 매우 중요한 분야로 인식되어 왔다. 그럼에도 불구하고 지금까지 문화산업에서는 기업가의 역할보다는 개인 창작자의 영감과 아이디어 등에 주로 초점을 맞추어 왔다. 하지만 최근 "한류(韓流)" 등의 영향으로 인해 문화산업에서 기업가의 역할이 중요해지고 있다. 이에 본 연구에서는 리더의 혁신지향성, 위험감수성, 선발자우위, 종업원에 대한 보상, 재도전용이성이 마켓리더십에 미치는 영향에 대해 분석하였다. 그 결과, 위험감수성, 선발자우위, 종업원에 대한 보상, 재도전용이성의 경우에는 모두 마켓리더십에 긍정적인 영향을 미치고 있었으나, 리더의 혁신 지향성에서는 유의미한 결과가 도출되지 못하였다. 이는 문화산업에서 마켓리더십을 가지기 위해서는 리더의 직관보다 구성원들의 창의성이 발휘될 수 있는 환경 조성이 더 효과적임을 보여준다. 본 연구의 결과는 문화산업에 속하는 기업들이 전략을 수립하거나 정부에서 정책을 결정할 때, 기업가정신이 강조되어야 함을 시사한다.

Purpose: This study attempted to examine the risk of stock price plunge according to the firm's management strategy. Prospector firms value innovation and have high uncertainties due to rapid growth. There is a possibility of lowering the quality of financial reporting in order to meet market expectations while withstanding the uncertainty of the results. In addition, managers of prospector firms enter into compensation contracts based on stock prices, thus creating an incentive to withhold negative information disclosure to the market. Prospector firms' information opacity and delays in disclosure of negative information are likely to cause a sharp decline in share prices in the future. Research design, data and methodology: This study performed logistic analysis of KOSPI listed firms from 2014 to 2017. The independent variable is the strategic index, and is calculated by considering the six characteristics (R&D investment, efficiency, growth potential, marketing, organizational stability, capital intensity) of the firm. The higher the total score, the more it is a firm that takes a prospector strategy, and the lower the total score, the more it is a firm that pursues a defender strategy. In the case of the dependent variable, a value of 1 was assigned when there was a week that experienced a sharp decline in stock prices, and 0 when it was not. Results: It was found that the more firms adopting the prospector strategy, the higher the risk of a sharp decline in the stock price. This is interpreted as the reason that firms pursuing a prospector strategy do not disclose negative information by being conscious of market investors while carrying out venture projects. In other words, compensation contracts based on uncertainty in the outcome of prospector firms and stock prices increase the opacity of information and are likely to cause a sharp decline in share prices. Conclusions: This study's analysis of the impact of management strategy on the stock price plunge suggests that investors need to consider the strategy that firms take in allocating resources. Firms need to be cautious in examining the impact of a particular strategy on the capital markets and implementing that strategy.
