The purpose of this study is to investigate how the vendor suitability factor affects ERP introduction factors of domestic small and middle businesses and internal performance. When domestic firms introduce an ERP package, they mostly use the package already developed by ERP firms. Therefore, this study tried to analyze that the suitability factor of an ERP package supplier serves as a moderating role for ERP internal performance. The study result showed that the vendor suitability factor played a moderating role for ERP introduction factors and internal performance. In other words, the vendor suitability factor served a moderating role for four factors -CEO support, education/training, users' IT capability, and business standardization /formulation- and internal performance. But, it was analyzed that the vendor suitability factor didn't serve as a moderating role for IT infrastructure and internal performance.

This study analyzed whether the suitability of strategy is playing a regulative role between IT characteristics & user characteristics and non-financial performance empirically. To this end, this study set up IT characteristics and user characteristics as independent variables, and set up non-financial performance as the performance variable of KMS, and also set up the suitability of the management strategy & informatization strategy of a business as moderating variables. This study defined the detailed factors in IT characteristics as IT maturity and IT/IS infrastructure while defining the detailed factors in user characteristics as perceived profit, organizing of learning, and user professionalism. In addition, this study defined non-financial performance as an organization member satisfaction, and KMS availability. As a result of the analysis, IT maturity & IT/IS infrastructure, which are defined as IT characteristics, and perceived profit, organizing of learning and user professionalism, etc., which were defined as user characteristics, were found to be variables playing a regulative role in non-financial performance.

This paper is to study adequacy of developing tutorial series for primary school students regarding MOS certification and to analyze a validity. In order to analyze a level of difficulty, current primary teaching materials being used after class, in comparison with ICT discretionary hour materials being used through primary discretionary class, were evaluated. It was done by primary teachers with in- depth understanding of a level of difficulty and after class instructors using Likert scale through quantitative analysis. As a result, level of PowerPoint has a satisfactory fit (76%), however, the degree of difficulty of Word and Excel is quite high. On its subject matter, there is quite a dispute with present curriculum. Therefore, in order to introduce MS-Word or Excel, it is necessary to adjust a level of difficulty or related subjects according to the level of students.

Accurate inference of parameters of a stochastic rainfall generation model is essential to improve the applicability of the rainfall generation model which modeled the rainfall process and the structure of rainfall events. In this study, the model parameters of a stochastic rainfall generation model, NSRPM (Neyman-Scott rectangular pulse model), were estimated using DFP (Davidon-Fletcher-Powell), GA (genetic algorithm), Nelder-Mead, and DE (differential evolution) methods. Summer season hourly rainfall data of 20 rainfall observation sites within the Nakdong river basin from 1973 to 2017 were used to estimate parameters and the regional applicability of inference methods were analyzed. Overall results demonstrated that DE and Nelder-Mead methods generate better results than that of DFP and GA methods.

The purpose of this study is to investigate the cases of cooperation between school libraries and public libraries in order to reinforce their cooperation, and to prepare the base for development of school libraries. Data is collected through five workshops which attended school librarians, public librarians, and the peoples in the several regional offices of education. The results show three models of school and public library cooperation. School library - public library cooperation model is suited for metropolitan area where school library and public library are developed. Public library support model is suited for mid-size cities where school libraries are undeveloped. School library and public library integration model is suited for small towns where both school libraries and public libraries are undeveloped. These models, however, should be revised through testing several libraries and different situations.

The purpose of this study was to verify the causal relations among related factors of job and life satisfaction among 805 wage workers with disabilities. The study conducted a path analysis using the $8^{th}$ Panel survey of Employment for the Disabled data. The results are as follows. Firstly, the life satisfaction scale was categorized into the human relationship satisfaction and the material environment satisfaction by an explorative factor analysis. These two satisfactions are directly affected by Job Satisfaction (JS) and Job Involvement (JI), not directly affected by Job Engagement (JE). Secondly, JS and JI have a complete mediated effect on the path from JE to these two satisfactions. Thirdly, an indirect effect in the path reaching JS was shown to be significant in a dual mediating effect through JS and JI. Based on this study, it is recommended the way of vocational rehabilitation counseling and the related supporting strategies and programs devise toward a JS of wage workers with disabilities, vocational rehabilitation field practitioners and professionals should consider properly intervening job factors.

The purpose of the study was to examine the mediating effect of self-esteem on the convergent relationship between respect for human rights and school adjustment of adolescents. Data came from the Korean Survey on the rights of Children and Youth in 2016 and a total of 2,366 of the 2nd grade students in middle school were employed. Structural equation modeling approach was utilized to test the goodness of research model fit and especially the mediating effect was tested by bootstrapping method. Results showed that goodness of model fit was acceptable and self-esteem mediated the convergent relationship between respect for human rights and school adjustment of adolescents. This indicates that the more experiences in respect for human rights and the higher their self-esteem students have, the better school adjustment they acquire. The results of the study imply that it is necessary to expand the human rights education for teachers and develop a new educational program that links between respect for human rights and self-esteem.

This study developed a HSI for the creatures in Hongcheon River in order to analyze the conditions proper for habitats. For the index, the investigator identified a total of seven items encompassing hydraulic characteristics such as flow velocity and water depth, and water quality characteristics such as water temperature, BOD, DO, TN, and TP. The subject river was simulated, inspected, and revised with a two-dimensional river model (RMA-2) and water quality model (QUAL2E). Using GIS, the developed index was divided by section by reflecting river characteristics and compared and analyzed with the statistics. The river was divided into a total of 29 reaches by reflecting the basic characteristics and the features of the hydraulic coefficient on the cross-sections of the river. According to the analysis results, the fish scored the highest mean of the overall habitat suitability index of 0.769 at reach 27. Each of the variables had the following mean values: 0.122 m/s for flow velocity, 0.782m for water depth, $14.3^{\circ}C$ for water temperature, 0.68 mg/l for BOD, 10.3 mg/l for DO, 2.4 mg/l for TN, and 0.0121mg/l for TP.

The purposes of the present study were (1) to identify the latent classes depending on youth employees' trajectories in job satisfaction and turnover intention and (2) to test the effects of person-job fit(major fit, education level fit, skill level fit) on job satisfaction and turnover intention using Youth Panel 2001. In order to estimate latent classes of job satisfaction and turnover intention changes simultaneously and study probabilities linking latent class membership in trajectory across the two variables, we applied dual trajectory model, an extension of semi-parametric group-based approach, Results showed that four latent classes were identified for job satisfaction, which were defined, based on the trajectory patterns, as increasing group, decreasing group, medium-level group, and high-level group. And, three latent classes estimated for turnover intention were defined as low-level group, maintaining group, and rapidly decreasing group. To test the effects of person-job fit variables, we added the variables as time-dependant variables to the unconditional latent class model. The effect of education level fit and skill level fit were found significant in the groups which are low in job satisfaction and have high in turnover intention. Findings from this study suggest the need to consider trajectory heterogeneity in the study of youth employees' job satisfaction and turnover intention to capture the dynamic dimension of overlap between the two constructs.
