The purpose of this study is to help create environments for early childhood education according to the principles of Constructivism. Generally, preschools in Ulsan Metropolitan City were used as samples for this study More particularly, 116 kindergartens were surveyed by telephone to evaluate their education programs. Four kindergartens that completely or partially used Constructivism in their programs were chosen as primary subjects for this study The results of this study were as follows: First, it was discovered that preschool education in Ulsan uses an integrated education model based on activities and Montessorie. Constructivist programs were also present using Project Approach, Reggio Emilia and Piaget. Second, the number of infants per class averaged 29.3. The average infants per playroom was 2.38$m^2$. It seems, therefore, that there is a lack of sufficient space for activities. Playroom furniture is primarily used for storage and it lacks variety and flexibility of use. The interior of preschools in related to materials, color and images also showed little difference among schools. Third, it was found that virtually every play space did not have adequate water playing and sand playing sections. Instead, the space for the large-muscle activities of big groups was used for this purpose. Fourth, kindergartens that use the principles of Constructivism plan to specialize their activities. Those only partially using Constructivism showed conventional tendencies and small play spaces that would be defined as inadequate according to Constructivism. This study, therefore, demonstrates that preschool education based on Constructivism are not being well-implemented in concert with other programs.

Objective: This study aims to implement an ecological transition education program for young children, based on a project approach, to investigate its effectiveness in enhancing sustainable development awareness, ecological literacy, and problem-solving skills. Methods: In this study, 56 five-year-old children from a preschool in S City were assigned to either a quasi-experimental group or a control group, with 28 children in each group. The project-based ecological transition education program for young children was conducted from July 14 to September 15, 2023. The experimental group explored the themes of 'marine life' and 'pets and animal welfare,' while the control group focused on different topics. The research employed independent sample t-tests and analysis of covariance (ANCOVA) for data analysis. Results: The project-based ecological transition education program effectively enhanced young children's awareness of sustainable development, ecological literacy, and problem-solving skills. Conclusion/Implications: This study is significant in developing an integrated, project-based ecological transition education program within a play-centered curriculum. It demonstrates how sustainable values can be effectively incorporated into play. Furthermore, the findings can serve as foundational data for implementing educational and childcare programs that nurture young children to become ecological citizens, leading sustainable futures.

Active attention and effort are needed to develop an integrated water management system in response to climate change. In this study, it proposed models for cross-use of agricultural water and river maintenance water using sewage treatment water as an integrated water management system for the Yeongsan River. The impact of the integrated water management models was assessed by applying the concept of Nexus, which is being presented worldwide for sustainable resource management. The target year was set for 2030 and quantitatively analyzed water, energy, land use and carbon emissions and resource availability index by integrated water management models was calculated by applying maximum usable amount by resource. An integrated water management system evaluation model using the Nexus concept developed in this study can play a role that can be viewed in a variety of ways: security and environmental impact assessment of other resources. The results of this research will be used as a foundation for the field of in the establishment of a policy decision support system to evaluate various security policies, as we analyzed changes in other factors according to changes in individual components, taking into account the associations between water, energy, food, and carbon resources. In future studies, additional sub-models need to be built that can be applied flexibly to changes in the future timing of the inter-resource relationship components.

Melanogenesis is the production of melanin from tyrosine by a series of enzyme-catalyzed reactions, in which tyrosinase and DOPA oxidase play key roles. The melanin content in the skin determines skin pigmentation. Abnormalities in skin pigmentation lead to various skin pigmentation disorders. Recent research has shown that the expression of EMP2 is much lower in melanoma than in normal melanocytes, but its role in melanogenesis has not yet been elucidated. Therefore, we investigated the role of EMP2 in the melanogenesis of MNT1 human melanoma cells. We examined TRP-1, TRP-2, and TYR expression levels during melanogenesis in MNT1 melanoma cells by gene silencing of EMP2. Western blot and RT-PCR results confirmed that the expression levels of TYR and TRP-2 were decreased when EMP2 expression was knocked down by EMP2 siRNA in MNT1 cells, and these changes were reversed when EMP2 was overexpressed. We verified the EMP2 gene was knocked out of the cell line (EMP2 CRISPR/Cas9) by using a CRISPR/Cas9 system and found that the expression levels of TRP-2 and TYR were significantly lower in the EMP2 CRISPR/Cas9 cell lines. Loss of EMP2 also reduced migration and invasion of MNT1 melanoma cells. In addition, the melanosome transfer from the melanocytes to keratinocytes in the EMP2 KO cells cocultured with keratinocytes was reduced compared to the cells in the control coculture group. In conclusion, these results suggest that EMP2 is involved in melanogenesis via the regulation of TRP-2 expression.

Medical errors such as adverse drug event, improper transfusion, wrong-site surgery, mistaken patient identity and so on commonly occur at health care practice. Information technology, like Drug Utilization Review(DUR) system which reviews, analyzes, and interprets medication data when prescribing, can play a key role in reducing such medical errors and improving patient safety. Korean Government has guided all hospitals to implement concurrent DUR(cDUR) system, which is the first case worldwide in that all healthcare providers have to use cDUR system when prescribing. This paper introduced a case study that a tertiary hospital has integrated the cDUR system into its comprehensive Hospital Information System(HIS) and analyzed the whole prescription data during a week right after adoption of cDUR system. Considering technical strength and weakness, the cDUR system was integrated into the HIS, using Broker Servers for minimizing doctors' anxiety. As the quantitative analysis of the whole prescription data, DUR conflict events, which mainly included duplicate medications and contra-indicated drug interactions for outpatients, were 2.77%. Although only 0.7% is for the contra-indicated drug interactions, it will be greatly devoted to achieve the purpose of DUR such as improving patient safety.
