The purpose of this study is to analyze the research trends for unmet medical care. As a research method, the research trend analysis of the paper was used. The target of analysis was analyzed as the final selected sample of 114 journals, doctoral dissertations, and master's dissertations published from 2008 to March 2020. The results of the analysis were steadily released starting from 2008 for each presentation period, and active research has been conducted since 2015. By research subjects, research was conducted in various classes, by research studies, the most active research was conducted in health sciences, research was conducted in other academic fields, panel data was used the most, and research methods were studied by quantitative research, Anderson social behavior model was used as the research model, and frequency analysis and logistic regression were used as the analysis method. This study is a quantitative study, In particular, studies should be conducted by applying longitudinal studies and qualitative studies rather than cross-sectional studies, and diverse models rather than single models. 본 연구의 목적은 미충족의료에 대한 연구 경향의 분석하는 것이다. 연구 방법으로는 논문의 연구경향분석을 사용하였다. 연구경향성분석 방법은 내용분석을 사용하였다. 분석 대상은 2008년부터 2020년 3월까지 발표된 학술지, 박사학위논문, 석사학위논문 중 114편을 최종 선정한 표본으로 분석하였다. 분석 결과는 발표시기별로는 2008년을 시작으로 꾸준히 발표되었고 2015년 이후 활발한 연구가 진행되었다. 연구대상별로는 다양한 계층에서 연구 진행되었으며, 연구학문별로는 보건학에서 가장 활발한 연구가 진행되었고 다른 학문영역에서 연구가 진행되었으며, 연구자료는 패널 자료가 가장 많이 사용되었고, 연구방법은 양적연구로 연구 되었으며, 연구모델은 앤더슨 사회행동모델이 사용되었으며, 분석방법은 빈도분석과 로지스틱 회귀분석이 사용되었다. 본 연구는 결과를 통해 양적 연구, 특히 횡단연구보다는 종단연구 및 질적 연구, 단일 모델보다는 다양항 모델을 적용하여 연구가 이루어져야 한다.

본 연구에서는 환형수조를 이용한 침식실험을 통하여 국내 최초로 퇴적저면의 침식매개변수들이 정량적으로 산정되었다. 퇴적저면은 고농도의 고령토 슬러리를 기 설정된 시간 동안 압밀시켜 조성되었으며, 각기 다른 압밀구조를 갖는 퇴적저면 조건 하에서 총 4회의 침식실험이 수행되었다. 침식실험 결과에 따르면, 흐름전단응력 ${\tau}_b$에 대한 저항력을 나타내는 저면전단강도 ${\tau}_s$는 압밀시간 및 저면(퇴적층) 깊이가 깊어짐에 따라 증가하는 것으로 나타났다. 한편, 침식률${\epsilon}$은 흐름전단응력과 저면전단강도의 차로 주어지는 잉여전단응력 ${\tau}_b-{\tau}_s$과 상관성이 매우 큰 것으로 나타났는데, ${\tau}_b-{\tau}_s{\leq}0.1N/m^2$인 경우에 침식률의 로그 값은 잉여전단응력과 선형적 관계에 있으나, ${\tau}_b-{\tau}_s{\leq}0.1N/m^2$인 조건에서는 잉여전단응력이 작아질수록 침식률이 급격하게 작아지는 경향이 있는 것으로 나타났다. 또한 본 연구에서는 과거 연구결과와의 비교검토를 통하여 본 침식실험 결과에 대한 타당성이 입증되었으며, $0.1N/m^2$ 이하의 잉여전단응력 구간에서 침식률을 보다 잘 표현할 수 있는 새로운 침식률 산정식이 제시되었다. In this study, the erosional parameters for deposit beds were quantitatively estimated domestically for the first time through the erosion tests using an annular flume. Four erosion tests were carried out for the deposit beds with different consolidation structures, which were obtained by consolidating the kaolinite slurries for a given time durations. Results of erosion tests showed that the bed shear strength ${\tau}_s$ increased with the consolidation time and bed depth. The erosion rate ${\epsilon}$ was also shown to be related well with the excess shear stress ${\tau}_b-{\tau}_s$ which was given by the difference between flow shear stress ${\tau}_b$ and bed shear strength ${\tau}_s$. While the logarithm of the erosion rate was linearly related with the excess shear stress as ${\tau}_b-{\tau}_s{\geq}0.1N/m^2$, however, the erosion rate decreased rapidly with it when ${\tau}_b-{\tau}_s{\leq}0.1N/m^2$. These erosion test results were also shown to be good enough to verify by comparing with the test results from previous studies and a new equation was suggested to describe the erosion rate more well in the region of ${\tau}_b-{\tau}_s{\leq}0.1N/m^2$.

소기업 CEO의 변혁적 리더십이 직원의 혁신행동에 미치는 영향
김용묵,신호철 한국품질경영학회 2019 품질경영학회지 Vol.47 No.1
Purpose: Despite the fact that the majority of domestic firms are small in size, there have been few studies conducted to understand the leadership effectiveness of small firm CEOs. Based on the upper echelon theory, this study attempts to demonstrate empirically that transformational leadership of small firm CEOs can increase the innovative behavior of employees. In addition, the present study examines mediating effects of CEO trust perceived by employees when transformational leadership affects employees’ innovative behavior. Methods: The survey data of CEOs’transformational leadership, innovative behavior of employees, and perceived CEO trust were collected from 176 employees working in domestic small firms. Hierarchical regression analyses were performed to examine the main effects between transformation leadership and innovative behavior and mediating effects of emotional labor strategy. Results: The results show that CEOs’ transformational leadership is significantly related to the innovative behavior of employees in the current sample. Results also indicate that CEO trust perceived by employees reveals a mediating effect in the process of transformational leadership affecting innovative behavior. Conclusion: The results show that as suggested by the upper echelon theory, the leadership of small firm CEOs can have a significant impact on positive job-related behaviors and attitudes of employees. The results also contribute to expand on the understanding of the relationship between transformational leadership and innovative behavior by explaining that transformational leadership can mediate trust in CEOs in enhancing employees’innovative behavior. Theoretical and practical implications are reviewed, and limitations of the study and suggestions for future research are addressed.

The purpose of this study is to analyze the efficiency of 29 cultural tourism festivals held continuously from 2015 to 2017 using the DEA model, identify the causes of inefficient festivals, suggest improvement plans, and provide a benchmarking reference group in operation and quantitative target scores. As a result of the study, first, Six festivals in 2015 and five in 2016 and 2017 were analyzed as efficient festivals among domestic cultural and tourism festivals. Second, there are 15 festivals that correspond to IRS, and there are 55 festivals in total which correspond to DRS, indicating that there is a need to improve the operation methods of the cultural tourism festival, rather than expanding the size of the festival. Third, among the reference groups, the Jindo Miracle Sea Road festival was held 20 times in 2015 and 2016, and Jarasum jazz festival was held 21 times in 2017. The implication of this study is to suggest a strategic direction to enhance the qualitative growth and competitiveness of domestic culture tourism festivals by suggesting a methodology to evaluate objectively the performance of culture tourism festival.
