This study was conducted to identify the effects of medium sized hospital nurses' nursing intention, infection prevention environment, and social psychological well-being on infection control performance of COVID-19 outbreak. The data collection period was from May 2 to May 31, 2022, and the questionnaires of 161 nurses who were working at I and B medium sized hospital in incheon and agree to participate in this study, were analyzed. Using the IBM SPSS/Win 25.0, the collected data was analyzed through the descriptive statistics, t-test, ANOVA, Pearson correlation, and multiple regreβion analysis. As a result, the infection prevention environment(β=.225, p<.001) and the experience of participating in new infectious disease education(β=.208, p=.008) had a significant effect and these variables were found to have 10.9% explanatory power for COVID-19 related infection control performance. Therefore, in the context of the outbreak of COVID-19, it is important to create an environment for infection prevention and to provide continuous and diverse education related to infectius diseases.

The purpose of this study was to analyse the qualitative and quantitative characteristics of paper-pencil tests for exploring its appropriateness as a selection tool of the gifted in science. For this purpose, we developed two (internal and external) item analysis frameworks, and applied these frameworks to analyse qualitative characteristics. Also, we analysed the relationship between two characteristics. The results of analysing qualitative characteristics revealed that the portion of items with acceleration context exceeding middle school curriculum level was relatively large, which caused low content validity. Furthermore, there was considerable deviation in content and context by subject matter and year, which caused test unstability. Items measuring knowledge domain was the most prevalent, and too much weight on data interpretation & analysis domain in inquiry process skills. In case of creativity test, the portion of items measuring convergent thinking was much larger than that of divergent or associative thinking. Most of these items were represented by using pictures and tables rather than using graphs. Item types of multiple-choice and short answers were superior to essay types. Discrimination index, on the whole, was appropriate (above 0.3), but item difficulty showed a vast deviation ($0.01{\sim}0.90$). Correlation coefficients among subject matters and test tools were very low, and test reliabilities were also low. Low item difficulty & high discrimination index item types were distinguishable. Items with acceleration context were more discriminating than enrichment context. Implications of developing quality paper-pencil test items in the selection of gifted students are discussed.

In this study, 17 formative assessments using cartoon were developed for studying 'genetics and evolution' chapter in textbook of third grade of junior high school. And those were applied to 73 students in experimental group and 78 students in control group. We investigated if there was positive effect on students' perception, attitude about assessment and scholastic achievement. As a result, we could find the formative assessments using cartoon were effective to change students' negative perception and attitude to positive one. Especially, those were effective to make students to understand usefulness of assessment (p<.05), and to decrease a feeling of uneasiness about assessment (p<.01). Also, we could find the developed formative assessments using cartoon had more positive effect on raising scholastic achievement than formative assessment using descriptive passage (p<.05). It was considered that this was because the abstract concepts of 'genetics and evolution' chapter were described in pictures, so contexts of textbook and assessment questions became easier to understand. So, we could conclude that formative assessment using cartoon contributed to increase students' understanding of contexts of textbook and to increase their interests about study. And if this assessment method is applied to class actively, students' feeling of uneasiness about assessment can be easily overcome and it can also give them positive perception about assessment.

This study presents a plan for a memorial park that respects the characteristics based on the historical facts for the concept of space of the Gwangju Hospital of Korea Army and the location of the 505 Security Forces, which were designated as historic sites after the 5-18 Democratization Movement. The Gwangju Metropolitan City as it is the location of the 5-18 historic sites, is taking part in the 5-18 Memorial Project, and plans to establish a city park recognizing the historic site of the 5-18 Democratization Movement, which has been preserved only as a memory space to this point. The park is promoting a phased development plan. This study suggests that the 5-18 historic sites can be modernized and that social consensus can establish the framework of the step-by-step planning and composition process to ensure the plans for the space heals wounds while preserving the history. In this paper, we propose a solution to a problem. We solve the approach for space utilization through an analysis of precedent research and planning cases related to park planning at historical sites. In addition to exploring the value of the site, we also describe the space utilization strategy that covers the historical characteristics and facts while maintaining the concept of park planning. As a result of the research, the historic site of the Gwangju Hospital of Korea Army is planned as a park of historical memory and healing in order to solve the problems left behind by the 5-18 Democratization Movement. The historic site of the 505 Security Forces was selected as an area for historical experiences and a place for learning that can be sympathized with by future generations of children and adolescents in terms of expanding and sustaining the memory of the 5-18 Democratization Movement. In the planning stage, the historical sites suggested the direction of space utilization for representation as did the social consensus of citizens, related groups, and specialists. Through this study, we will contribute to construction of a memorial park containing historical values in from 5-18 historic sites. It is meaningful to suggest a direction that can revitalize the life of the city as well as its citizen and can share with the history with future generations beyond being a place to heal wounds and keep alive the memory of the past.

It is increasingly supported by scientific evidence that greenhouse gas caused by human activities is changing the global climate. In particular, the changing climate has affected human health, directly or indirectly, and its adverse impacts are estimated to increase in the future. In response, many countries have established and implemented a variety of mitigation and adaptation measures. However, it is significant to note that climate change will continue over the next few centuries and its impacts on human health should be tackled urgently. The purpose of this paper is to examine domestic policies and research in health sector in adaptation to climate change. It further aims to recommend future research directions for enhanced response to climate change in public health sector, by reviewing a series of adaptation policies in the selected countries and taking into account the general features of health adaptation policies. In this regard, this study first evaluates the current adaptation policies in public health sector by examining the National Climate Change Adaptation Master Plan(2011~2015) and Comprehensive Plan for Environment and Health(2011~2020) and reviewing research to date of the government and relevant institutions. For the literature review, two information service systems are used: namely, the National Science and Technology Information Service(NTIS) and the Policy Research Information Service & Management(PRISM). Secondly, a series of foreign adaptation policies are selected based on the global research priorities set by WHO (2009) and reviewed in order to draw implications for domestic research. Finally, the barriers or constraints in establishing and implementing health adaptation policies are analyzed qualitatively, considering the general characteristics of adaptation in the health sector to climate change, which include uncertainty, finance, technology, institutions, and public awareness. This study provides four major recommendations: to mainstream health sector in the field of adaptation policy and research; to integrate cross-sectoral adaptation measures with an aim to the improvement of health and well-being of the society; to enhance the adaptation measures based on evidence and cost-effectiveness analysis; and to facilitate systemization in health adaptation through setting the key players and the agenda.

Learning progressions (LP), which describe how students may develop more sophisticated understanding over a defined period of time, can inform the design of instructional materials and assessment by providing a coherent, systematic measure of what can be regarded as "level appropriate." We developed LPs for the nature of matter for grades K-16. In order to empirically test Korean students, we revised one of the constructs and associated assessment items based on Korean National Science Standards. The assessment was administered to 124 Korean secondary students to measure their knowledge and submicroscopic representations, and to assign them to a level of learning progression for the particle nature of matter. We characterized the level of students' understanding and models of the particle nature of matter, and described how students interpret various representations of atoms and molecules to explain scientific phenomena. The results revealed that students have difficulties in understanding the relationship between the macroscopic and molecular levels of phenomena, even in high school science. Their difficulties may be attributed to a limited understanding of scientific modeling, a lack of understanding of the models used to represent the particle nature of matter, or limited understanding of the structure of matter. This work will inform assessment and curriculum materials development related to the fundamental relationship between macroscopic, observed phenomena and the behavior of atoms and molecules, and can be used to create individualized learning environments. In addition, the results contribute to scientific research literature on learning progressions on the nature of matter.

As a scientific curiosity to understand the structure and the function of crops and experimental efforts to apply it to plant breeding, genetic maps have been constructed in various crops. Especially, in the case of Brassica crop, genetic mapping has been accelerated since genetic information of model plant $Arabidopsis$ was available. As a result, the whole $B.$ $rapa$ genome (A genome) sequencing has recently been done. The genome sequences offer opportunities to develop molecular markers for genetic analysis in $Brassica$ crops. RFLP markers are widely used as the basis for genetic map construction, but detection system is inefficiency. The technical efficiency and analysis speed of the PCR-based markers become more preferable for many form of $Brassica$ genome study. The massive sequence informative markers such as SSR, SNP and InDels are also available to increase the density of markers for high-resolution genetic analysis. The high density maps are invaluable resources for QTLs analysis, marker assisted selection (MAS), map-based cloning and comparative analysis within $Brassica$ as well as related crop species. Additionally, the advents of new technology, next-generation technique, have served as a momentum for molecular breeding. Here we summarize genetic and genomic resources and suggest their applications for the molecular breeding in $Brassica$ crop.

The narratives of the digital age have attempted interactions, and the interactive storytelling represented by the Branch Narratives has a problem of the expensive production cost of many optional implementations and poor narrative compared to linear story. As an alternative to this, this study proposes a user-oriented storytelling using user's personality traits. Using the Enneagram, a model of human psyche, and the Actantial model of the semiotician Greimas, when stories and characters are the same, the story could be reconstructed by deriving different topics from the same story according to the user's Enneagram personality type. The theme is determined by defining the axis of the desire of the Actantial model by respectively setting the character with the user's Enneagram type as the subject and the core value in the type as the object. The axis of Power could be defined by the stress and security points in Enneagram. In this way, we can derive the themes of 9 Enneagram types and the corresponding Actantial model and make plots. The users will appreciate one of these reconstructed plots in different perspectives and themes, depending on their personality type. In this study, we applied the above methodology to the story of the pansori novel "Tokkijeon". User-centered storytelling is a new attempt to predict user's choice and reconstruct the story based on the user's personality and perspective.

The purpose of this paper is to outline a research agenda for the evaluation of the sustainability of freshwater policies, especially as they relate to large cities in the Asia-Pacific region, and to co-work a comparative study on the cases of Seoul and Sydney on the basis of the research agenda. The overall long-tenn aim of the present research is to develop a framework for sustainable urban freshwater policy in the Asia-Pacific region. The nature of freshwater policies for a sample of 16 large cities in the Asia-Pacific region will be critically evaluated for 5 years in the future. For the purposes of this research agenda, four main types of urban water conflict have been evaluated - jurisdictional conflicts, conflicts related to accessibility, sectoral conflicts and environmental conflicts. Of course, in reality, aspects of these four types of conflict invariably overlap. In the case study, the environmental conflict over fresh water of Seoul can be seen as a jurisdictional, sectoral and accessibility-related conflict between the central government and Seoul local government which want to regulate the lan-use with the water conservation zone around the Paldang Dam located at a upstream of the Han River on the hand, and the Yangpyong local governmant and its population within the conservation zone which have struggled against such a regulation, on the other. In the case study on the Sydeny water crisis in 1998, the environmental conflict over fresh water of Sydney in Australia can be seen as a jurisdictional conflict between the State government and the Sydney local government and the corporatized Sydney Water which have been responsible to supply fresh water on the one hand, and the Sydney population who have been suffered from the contaminated water, on the other. Over the past ten years, both globally and in the Asia-Pacific region, including in S. Korea and Australia, the concept of sustainable development has taken on a growing role in the determination of environmental policy. The balance for sustainable policy would be between the requirement to augment water supply to cope with projected future demands and the need to improve efficiency of water use.

The purpose of this study was to investigate the types of conceptions of mixing phenomena related to dissolution and diffusion in high school students. The subjects of the investigation consisted of 108 students who took chemistry I course at 11th grade and 29 students who took chemistry II course at 12th grade. For this study, it was found that the many students had the alternative conception that chalk didn't dissolve in water because chalk was a nonpolar material. Most of the students understood the phenomena which carbon tetrachloride and water will not mix as the attraction conception. But many of the other students understood the phenomenon as characteristic of the materials such as difference of density. Many of the students understood the phenomenon of mixing ethanol and water constantly as ‘Attraction conception'. The phenomenon which is mixed ink and water was just accepted by the most students as the spreading of ink in water without understanding the reason of mixing. The phenomena of mixing iodine and carbon tetrachloride was understood as ‘Space conception' or ‘Attraction conception'. It could be inferred that the diverse alternative conceptions related to dissolution and diffusion phenomena were generated by the absence of entropy concept. Therefore, the explanations of science textbooks related to dissolution and diffusion phenomena need to change for students to understand them correctly.
