The importance of trade cooperation with foreign countries is becoming higher in order to utilize the competitiveness of its own country's industries. In Korea, the government has made various efforts to respond to the expansion of foreign trade cooperation. As time goes by, it is needed to redefine and reestablish the functions of industrial polices in order to improve the effectiveness and efficiency of foreign trade cooperation. We focus on the industrial and trade policies related to FTA. Mainly we do research the impact (before and after FTA) of industry, trade policies, and firms' management activities on the export-oriented firms. For this end we conduct a survey on the firms' evaluation of the trade related policies and analyze with the panel data regression model. According to the results, in order to enhance the utilization of FTA, the connection with export support program, the training of expert HRs, and the prohibition of double regulation are the main influential policies.

Though school leaders play a crucial role in encouraging the creative school environment, culture, and system that might improve the creative competencies of teachers, there has been little attention to the creative leadership of school supervisors. In this paper, we provide the satisfaction and view of elementary and secondary school leaders who were involved in professional development training for enhancing creative leadership. Using one-way ANOVA and qualitative data coding, we analyze the survey responses from the 67 in-service principals and vice-principals during three different training periods as 2020-I, 2020-II, and 2021-I. We present and compare the result on their satisfaction in terms of satisfaction regarding the process, administrative supports, and optional programs among the training. Next, we explore how the school administrators think the creative leadership training and proposal for its improvement. Based on the feedback for these stakeholders, further studies need to steadily enhance the professional development training for creative leadership and practical program contents.

분류층 가스화기는 석탄과 산소(공기) 및 수증기가 반응하여 $1200{\sim}1600^{\circ}C$의 고온, 20~60기압의 고압에서 작동되어 합성가스를 생성하며 합성가스에 포함된 입자 및 황화합물 등을 정제설비를 통하여 정제 후 발전 및 화학원료로 사용한다. 석탄가스화 중 석탄에 포함된 대부분의 회분은 용융슬래그 형태로 가스화기 벽면을 따라 흘러 내려 가스화기 하부의 냉각수조에서 급랭되어 배출된다. 이때 용융슬래그의 원활한 배출을 위해서는 일정범위의 점도를 유지하는 것이 필요하다. 슬래그의 점도는 가스화기 온도 및 Ash의 조성에 따라 크게 변하며 가스화기 설계 및 운전 시 매우 중요한 변수이다. 따라서 최적의 설계 및 운전을 위해서는 Ash의 점도예측이 중요하며, 분류층 가스화기내부에서 Ash 점도 예측을 위한 DooVisco 프로그램을 개발하였다. DooVisco는 가스화기 내부에서 슬래그 용융온도 및 온도별 점도, 가스화기 최소 운전온도 및 석회석 투입 효과 분석뿐만 아니라 석탄의 혼합 사용 시의 특성 예측도 가능하도록 개발되었다. DooVisco는 슬래그 주요 4성분인 SiO2, Al2O3, CaO, FeO 성분에 대한 Phase Diagram을 이용하여 1차적으로 슬래그용융온도(Liquidus Temperature)를 예측하고, 주요 4 성분 외에 Na2O, MgO, K2O, TiO2 등을 고려한 Kalmanovich Model을 이용하여 점도를 예측한다. 최종적으로 슬래그 용융온도와 점도를 활용하여 분류층 가스화기 운전가능 온도범위를 예측한다. 개발된 DooVisco를 활용하여 300MW급 실증 IGCC 플랜트에 사용가능성이 있는 석탄을 대상으로 슬래그의 용융온도 및 점도 등을 예측하였으며 최적 운전을 위한 슬form점도 조절용 Flux인 석회석 투입량 등을 평가하였다. 평가 결과 슬래그 용융온도가 $1700^{\circ}C$ 이상으로 석회석 투입이 필요하다고 판단되었다. 약 가스화기 내부 온도를 $1500^{\circ}C$ 정도에서 원활한 운전을 위해서는 석탄 대비 약 10% 내외의 석회석 투입이 필요할 것으로 평가되었다. DooVisco는 분류층 가스화기 설 계시 가스화기 최적 운전 온도 설정 및 Flux 투입필요성, 종류, 투입량 선정에 활용될 수 있을 뿐만 아니라 플랜트 운전시 석탄의 탄종 적합성 등을 판단하는데 활용될 수 있을 것이라 판단된다.

This study examined the effectiveness of maternity nursing simulations using a high-fidelity simulator for undergraduate nursing students. One-group pretest-posttest design was used. The simulation-based education program consisted of three sessions, including the clinical scenarios about prenatal, childbearing and postpartum care. The program provided for 3 weeks in November 2014. Data was collected before and after the simulation education using self-reported questionnaires, which included simulation effectiveness, problem solving ability, communication skills and self-confidence in maternity nursing. The data of 83 participants were analyzed using the IBM SPSS 20.0 program. After simulation education, the overall score of the simulation effectiveness was 17.4 out of 26.0. Communication skill (t=4.58, p=<.001) and self-confidence in maternity nursing (t=9.70, p=<.001) increased significantly in the posttest. On the other hand, there was no significant change in the problem solving ability. The simulation effectiveness correlated significantly with the problem solving ability (r=.494, p<.001), communication skill (r=.361, p<.001), and self-confidence in maternity nursing (r=.497, p<.001) after simulation-based education. These findings suggest that the high-fidelity simulation in maternity nursing education could be used not only to enhance the nursing competency, but also to deal with the limitations of the clinical practicum in the current situation.
