The purpose of this study was to develop and validate future teacher competencies diagnosis tools required for pre-service teachers. In this study, the hypothesis model was established by hierarchizing basic competency and job competency in three dimensions such as knowledge, practice, and personality as teachers' competencies required in future society. Based on this hypothesis model, 54 preliminary questions were developed, and competencies diagnosis test was conducted for 237 pre-service teachers in J area, Korea. The results of this study are as follows: First, as a result of this study, a total of 53 questions were extracted, including 18 questions with 6 factors in the knowledge dimension, 17 questions with 6 factors in the practice dimension, and 18 questions with 6 factors in the personality dimension. Second, the goodness-of-fit of future teacher competencies diagnosis model required was verified, and convergence and discriminant validity were verified. The results of this study were discussed. Finally, the implications and suggestions for further research were presented.

최근 전 세계적으로 많이 활용되는 MODIS영상은 250m 밴드 2개, 500m 밴드 5개, 1km 해상도의 밴드 29개로 제공된다. 그러나, 국내의 경우 상대적으로 국토 면적이 작고, 그 구조가 복잡하여 MODIS영상의 1km, 500m의 낮은 공간해 상도는 제약점으로 지적되고 있다. 따라서 본 연구에서는 이러한 공간해상도의 제약점을 해결하기 위해, MODIS 250m 2개 밴드와 500m 5개 밴드 영상을 합성하여 250m 공간해상도의 7개 밴드를 제작하였다. 이를 위해 Wavelet 합성방법을 비롯한 7개 합성방법을 적용하였으며, 6개의 통계적 합성 평가 척도를 적용하여 MODIS 합성 결과를 분석하였다. 연구 결과, 육안평가로는 LMVM 합성기법이 가장 선명한 합성영상을 제시하였으며, 합성평가 척도에서는 각 밴드별로 적합한 합성기법이 다르게 나왔으나, 전체적으로 PCA, LST, LMVM합성방법이 상대적으로 우수한 합성결과를 나타냈었다.

기상 데이터의 사용은 수문 모의에 있어서 필수적인 요소이다. 본 연구에서는 다양한 기상 자료를 사용하여 남한 전체를 대상으로 수문 모의를 진행하여 기상 데이터의 적합성을 판단하고자 한다. 이를 위하여 본 연구에서는 그리드 기반의 기상 자료로 강수 자료와 온도자료를 사용하였으며 그 적합성을 살펴보았으며 특히 강수자료는 총 11개로 6개의 위성기반 자료 (CMORPH, MSWEP, MERRA, TRMM 및 TRMM-RT)와 5개의 재분석 기반 자료 (ERA5, JRA-55, CPC-U, NCEP-DOE 및 K-Hidra)를 살펴보았고 온도자료는 4개의 자료 (MERRA, ERA5, CPC-U 및NCEP-DOE)를 선정하여 살펴보았다. 남한 전체를 대상으로 수문 모형을 구축하기 위하여 본 연구에서는 Variable Infiltration Capacity (VIC) 모형을 사용하였으며 총 44개의 조합 (강수자료 11개 × 온도자료 4개)에 비교 결과를 토대로 서로 다른 조합의 앙상블을 생성하여 수문 모의 결과를 비교하였다. 결과적으로 온도자료는 상대적으로 그 자료마다 모의 결과의 차이가 적게 나타났지만 강수자료는 자료에 따라 수문 모의 결과에 큰 차이를 보여 그 영향력이 큰 것으로 확인하였다. 이를 통하여 본 연구에서는 기상 자료가 수문모형의 성능에 영향을 미치기 때문에 적합한 기상 자료를 선정하는 것이 수문 모델링을 진행하기 전 단계로 필수적인 과정이라는 것을 확인했다.

Endophytic fungi are present in host plants and contribute to resistance to biotic and abiotic stress. Aquatic plants are living in aquatic environment such as saltwater or freshwater and exposed more water stress than other land plants. In this study, we investigated 4 wetlands in Jeju and collected 11 aquatic plants. Exogenous microbes were removed by preprocessing of plants and endophytic fungal strains were isolated from the plants. We isolated 126 fungal strains from Namsaengi-pond, 22 fungal strains from Sujangdong-marsh, 44 fungal strains from Yongsu-reservoir and 32 fungal strains from Gangjeongcheon. The fungal strains were identified using internal transcribed spacer (ITS) region and analyzed the phylogeny and diversity. Endophytic fungi isolated from plants of Namsaengi-pond were classified to 30 genera, 19 families, 12 orders, 7 classes and 4 phyla. Endophytic fungi of Sujangdong-marsh were classified to 11 genera, 11 families, 6 orders, 5 classes and 4 phyla. Endophytic fungi of Yongsu-reservoir were classified to 13 genera, 12 families, 7 orders, 5 classes and 4 phyla. Endophytic fungi isolated from Gangjeongcheon were classified to 9 genera, 7 families, 5 orders, 2 classes and 1 phyla. Overall, they were divided 40 genera and Alternaria, Colletotrichum and Fusarium were isolated from 4 sites in common. By investigating the endophytic fungi in aquatic plants, it is for baseline data that determination of diversity and the ecological distribution of endophytic fungi.

The purpose of this study is to examine the effects of organizational/job suitability and self-efficacy on the job enthusiasm of public officials to enhance the government's organizational performance and goal achievement, and to examine what mediating effects of self-efficacy have. As the subject and method of the study, a survey was conducted with 248 civil servants from three cities (P, U, Y) in Gyeonggi-do, and structural equation analysis was used for the collected surveys. As a result of the study, organizational suitability of public officials had a positive effect on job enthusiasm, and self-efficacy was found to have a partial mediating effect on organizational suitability and job enthusiasm. In the case of job suitability, job enthusiasm was not significant, and self-efficacy had a fully mediated effect. Based on the results of this study, administrative and policy implications for enhancing the enthusiasm for the job of front-line civil servants of administrative organizations were presented.

The purpose of this study is to present a more effective daily checklist than the formal routine check before the experiment to prevent accidents in the university laboratory. To do this, we reconstructed the current daily checklist and previous research data and conducted a second Delphi survey. As a result, there were four general safeties such as arranging the laboratory, three mechanical safeties such as abnormal condition of machine and tool tightening parts, three electric safeties such as prohibition of loading around the electric distribution panel, six chemical safeties such as handling and managing harmful factors, three items of fire safety such as fire extinguisher inspection, five cases of gas safety gas container inspection, one item of biological safety such as the state of hand sterilizer management and one other item, which were provided in the daily checklist as twenty six categories in total. According to the opinions of related experts, it is necessary to have an easy and simplified daily checklist for actual daily checkups.

The purpose of this study was to develop the evaluation scales that can access hierarchically the lifelong education field training program based on relevant stakeholders. To fulfill this purpose, both qualitative and quantitative research methods were applied. First of all, four groups of stakeholders were selected such as trainees, professors, field instructors, and program inspectors. The in-depth interviews with 13 experts in the field were conducted, and as a result, the scale with hierarchy of evaluation area, evaluation section, and evaluation item for each stakeholder was developed. In order to verify the content validity of the evaluation scales, delphi surveys for each stakeholder were conducted, using 35 expert panels. After delphi survey, the scale was applied to 90 trainees, 22 professors, and 31 field instructors. SPSS program was used to analyze the descriptive statistics, validity, and reliability. Finally, the evaluation scale of the trainer was identified as 8 evaluation areas, 14 evaluation sections and 51 evaluation items. And the professor's scale consisted of 6 areas, 10 sections and 40 items. The field instructor's scale was determined as 3 areas, 7 sections and 31 items, and the program inspector's evaluation scale was confirmed as 7 areas, 15 sections, and 32 items.

The purpose of this study was to identify the effect of person-environment fit and job embeddedness on turnover Intention. The subjects conveniently extracted 150 nurses who work at 2general hospitals in B and U metropolitan cities for more than six months, and Analyses were made using the SPSS WIN 20.0 and AMOS 21.0 programs to identify the causal relationship between person-job fit, person-organizational fit, person-supervisor fit, job embeddedness and turnover Intention. As a result, the variables with direct effect and total effect on job embeddedness showed personal-job fit, personal-organizational fit, person-supervisor fit and explained 76.3% of the job embeddedness. The most significant direct effect on turnover intention was job embeddedness and personal-job fit, personal-organizational fit, Person-supervisor fit showed indirect effect, and job embeddedness explained 36% of the turnover intention. In conclusion, if the personal-job fit, personal-organizational fit, and personal-superior fit of the clinical nurse are improved, the job embeddedness are improved turnover intention will decrease and the turnover rate will be decreased. In addition, it is necessary to study various factors affecting the turnover intention of person-environmental fit on nurses.
