The gridded simulation of crop growth, which would be useful for shareholders and policy makers, often requires specialized computation tasks for preparation of weather input data and operation of a given crop model. Here we developed an automated system to allow for crop growth simulation over a region using the DSSAT (Decision Support System for Agrotechnology Transfer) model. The system consists of modules implemented using R and shell script languages. One of the modules has a functionality to create weather input files in a plain text format for each cell. Another module written in R script was developed for GIS data processing and parallel computing. The other module that launches the crop model automatically was implemented using the shell script language. As a case study, the automated system was used to determine the maximum soybean yield for a given set of management options in Illinois state in the US. The AgMERRA dataset, which is reanalysis data for agricultural models, was used to prepare weather input files during 1981 - 2005. It took 7.38 hours to create 1,859 weather input files for one year of soybean growth simulation in Illinois using a single CPU core. In contrast, the processing time decreased considerably, e.g., 35 minutes, when 16 CPU cores were used. The automated system created a map of the maturity group and the planting date that resulted in the maximum yield in a raster data format. Our results indicated that the automated system for the DSSAT model would help spatial assessments of crop yield at a regional scale.
As much time is being spent with the family at weekends by the development of leisure culture, many people have begun to enjoy camping in the field. While many people use pensions or camping cars, many families or groups of friends go on camping in the summer holiday season. Although the tent design in this country has gradually been developed, it is not as developed as overseas designs with unique design characteristics according to climate, cultural behavior and colors. In this research, the American and Korea tent designs are compared in terms of color and frame. The differences are analyzed and a direction for tent designs appropriate for Korea in terms of size, area, ease of carriage and installation is proposed through theoretical data and idea sketches. The frame weight has been minimized and the durability increased for the ease of carriage and installation. The style and number of windows have been increased in order to provide a comfortable space by understanding the influx of airflow and the size of the tent has also been increased to provide extra space for storage. The information on the overseas and domestic tent design trends led to a color comparison and the extraction of images of language. The tent based on the new design is currently being mass-produced in China following 3 months of preparation including sample making and testing.
The purpose of this study was to develop and validate a Children's Play Disposition Scale(CPDS) which could be used to evaluate children's play patterns and preferences. The participants of this study were parents of 437 5-7-year-old children (age range from 51months to 106months). Preliminary items were developed through a review of relevant research, multiple intelligence theory and scales, confirmation of item adequacy and content validity. After the content validity was confirmed by experts, these items were edited down to a final list of 27 items representing 6 factors identified by exploratory factor analysis. The 6 factors of the scale consists of initiative, linguistic activity, logical-mathematical activity, art and craft, physical activity, and sensitivity respectively. Concurrent validity was established by using correlations between each factor of the CPDS and sub-factors and the total scores of Multiple Intelligence Checklist for preschoolers (Multiple Intelligence Institute Co., Ltd, 2008) and Multiple Intelligence Checklist for elementary schoolers (Multiple Intelligence Institute Co., Ltd, 2007). In addition, the reliability of each factor, as measured by Cronbach's ${\alpha}$, ranged from .53 to .79. The CPDS provides the developmental and educational information for strengthening children's developmental forte and for supporting children's developmental weakness. This scale can be used on developing children's play contents and guiding play methods in the future.
This is an exploratory study based on the literature reviews which examined the possibilities and necessities of multimodal writing curriculum for liberal education. The purpose of this study is to analyze the existing research results which utilized the teaching methods associating music and writing, and to find the educational implications, and finally in terms of writing education, to suggest the possibilities of writing classes' convergent forms with music extracted from the results of the existing studies. Those studies were categorized to four patterns: WAC, effects of therapy, materials for writing, and new literacy. Based on Meyrowitz's perspective, firstly music can be utilized as a circumstance, which means a teacher can indirectly take the emotional, reminding, and healing effects of background musics. Secondly, music can play an important role of materials in thinking and writing, which is the most generally utilized pattern today. The effects are found in all of affective, cognitive, and strategic domains by utilizing music as a sort of reading materials. Thirdly, the convergent writing of music and narrative is suggested. Music is an independent language that can interact with narrative and construct text meanings in this kind of writing classes. These three dimensions of convergence have different perspectives, but sometimes occur at a same time or as a connected pattern. This study proposes that writing teachers need to improve their competence in music as well and to have professional concerns and efforts to develop their convergent writing teaching skills with music for these classes. Finally, this study stresses that team teaching can be an alternative for them.
The purpose of this study is to deal with practical investigation, which blends symbolism on spatio-temporal level-especially typography in three-dimensional environment-and the symbolism of written language in the context of visual communication. Up until now, typography research and education have mainly been centered on two-dimensional environment and printing technology, such as the paper. However, this study is the result of this researcher's direct design and implementation of projects on typography aside from paper. Accordingly, this study is to provide an opportunity to raise the level of reason and expression used in visual communication to a new level and to expand its scope. To ensure the efficient progress of the project, this study was to identify the structure, system, and process of communication first. Furthermore, this study was to investigate two-dimensional and three-dimensional typography as the backbone of visual communication. In addition, several representative 3D typography works are analyzed in context and used as the conceptual framework of the project conducted for this study. Based on these results, this research verifies and suggests the possibility practically and objectively by creating the project series entitled Rhetorical Space in 3D typography. In addition, this research gives an opportunity to visualize ideas aimed at the development of character-based visual language and visual communication design in the realm of the more spatial, physical, and three-dimensional public environment.

Based on the theory of cognitive reserve, we undertook this study to develop a cognitive function training program for woman in menopausal transition with complaints of declining in cognitive function. The program was established by applying the analysis, design, and development stages of the network-based instructional system designed by Jung. The cognitive function training program developed by us is an was an 8-week program composed of cognitive and video training using a mobile application. The program consists of 24 sessions, each with 20-30 minutes of duration, to be completed 3 sessions per week. The contents of the cognitive function training comprise of memory, attention, language function, and scenario-based problem-solving for executive functions, all of which are cognitive areas found to be the most vulnerable for menopausal women. The educational contents were developed for eight subject areas, one subject area per week, including the definition of menopause, its causes and symptoms, menopause and brain function, etc. During the pilot test, the cognitive function training program was applied to 10 menopausal women who complained of cognitive function decline. The results indicated that, after eight weeks of training, the overall cognitive function of participants increased, revealing statistically significant differences (t=-3.04, p=.014) after the program was completed. The mobile app-based cognitive function training program might not only improve patients' memory functions but also potentially reduce the incidence of dementia.

Cultural arts education helps in the holistic development of children and enhances their language skills and creative thinking. This type of education not only fosters emotional intelligence, but has also been proven to play a positive role in helping children understand different cultures. Based on these findings, in recent times, interest in cultural arts education has been focused on the importance of experiencing art in childhood and the development of artistic ability. A high standard of cultural arts education is desirable, in which regular classes are held based on the close cooperation of teachers, with extensive knowledge and sense of the cultural arts, and cultural arts experts. Therefore, it is necessary to include extensive cultural arts education in the training of early childhood educators, considering the importance of early childhood cultural arts education. This study suggested ways to improve the academic curriculum and develop plans to enhance the expertise of early childhood teachers in the field of cultural arts by analyzing the academic curriculum of early childhood education courses in 4-year universities in the metropolitan area.

The purpose of this study was to examine violence response, burnout, and job satisfaction according to violent episodes of emergency room workers. Methods : This Study was a descriptive survey design using convenience sampling. This study was exempt from needing an IRB approval. There were 167 emergency room workers, who agreed to participate in this study, and took a self-report questionnaire between July and August 2015. SPSS 21.0 version was used for descriptive analysis, frequency, percentage, mean, standard deviation, independent t-test, Pearson correlation coefficients, and multiple regression. The major findings of this study were as follows: 1) 84.4% of participant experienced violent episodes. The frequency of verbal violence was highest. Violent attackers were patients and guardians with drunken state. The time of violence episodes was usually during the night. Violent experience of doctors and nurses was very high. 2) There were significant differences in the emotional response according to violent episodes (t=2.528, p=0.12) 3) The correlation between \response and burnout was statistically significant, and indicates a high positive correlation (r=.616, p=<.001). The correlation between violence response and job satisfaction was statistically significant, indicating a negative correlation (r=-.512, p=<.001). There was a negative correlation between burnout and job satisfaction with statistical significance (r=-.568, p=<.001). 4) Significant factors influencing job satisfaction were emotional response to violence and burnout. Conclusion: The findings of this study provide basic information for the strategies of preventing violence, decreasing burnout, and improving job satisfaction by developing a violence management program.
As the complexity of SoC (System-on-Chip) design increases dramatically. traditional system performance analysis and verification methods based on RTL (Register Transfer Level) are no more valid for increasing time-to-market pressure. Therefore a new design methodology is desperately required for system verification in early design stages. and hardware software (HW-SW) cosimulation at TLM (Transaction Level Modeling) level has been researched widely for solving this problem. However, most of HW-SW cosimulators support few restricted ion levels only, which makes it difficult to integrate HW-SW cosimulators with different ion levels. To overcome this difficulty, this paper proposes a multipurpose framework for HW SW cosimulation to provide systematic SoC design flow starting from software application design. It supports various design techniques flexibly for each design step, and various HW-SW cosimulators. Since a platform design is possible independently of ion levels and description languages, it allows us to generate simulation models with various ion levels. We verified the proposed framework to model a commercial SoC platform based on an ARM9 processor. It was also proved that this framework could be used for the performance optimization of an MJPEG example up to 44% successfully.
