Recently, global luxury fashion brands such as Gucci, Saint Laurent, and Louis Vuitton have been showing special interest in Korean contemporary artists and actively collaborating with them. This can be said to be a new change that is distinguished from previous collaborations of fashion brands. Therefore, this study investigated the cases of collaboration between global luxury fashion brands and Korean contemporary artists, and analyzed the types and characteristics to examine the trends and characteristics and draw meaning. As a result, fashion brands combine the characteristics of Korean art works of various genres with the brand concept and pursued values to create new sensibility and high value-added products. It can be seen that the intention was to prepare a place to draw out. In addition, it was found that collaboration was also utilized in terms of marketing so that domestic customers could visit the brand store with a sense of familiarity by utilizing Korea's artistic and cultural sentiments. Based on the results of this study, we intend to provide basic data for the development of creative contents for various collaborations between fashion and art that can help develop the modern fashion industry.

A steam explosion may occur during a severe accident, when the molten core comes into contact with water. The pressurized water reactor and boiling water reactor ex-vessel steam explosion study, which was carried out with the multicomponent three-dimensional Eulerian fuel-coolant interaction code under the conditions of the Organisation for Economic Co-operation and Development (OECD) Steam Explosion Resolution for Nuclear Applications project reactor exercise, is presented and discussed. In reactor calculations, the largest uncertainties in the prediction of the steam explosion strength are expected to be caused by the large uncertainties related to the jet breakup. To obtain some insight into these uncertainties, premixing simulations were performed with both available jet breakup models, i.e., the global and the local models. The simulations revealed that weaker explosions are predicted by the local model, compared to the global model, due to the predicted smaller melt droplet size, resulting in increased melt solidification and increased void buildup, both reducing the explosion strength. Despite the lower active melt mass predicted for the pressurized water reactor case, pressure loads at the cavity walls are typically higher than that for the boiling water reactor case. This is because of the significantly larger boiling water reactor cavity, where the explosion pressure wave originating from the premixture in the center of the cavity has already been significantly weakened on reaching the distant cavity wall.

The effects of Sosokmyung-tang(小續命湯) on global cerebral ischemia and cerebral in farction by MCA(middle cerebral artery) occlusion were evaluated in this study. This study was performed to investigate that Sosokmyung-tang would be useful for cerebrovascular diseases. In the case of global cerebral ischemia, ICR mice were used and divided into three group at random. Control group was treated after oral administration of normal saline, experimental group was treated after oral administration of 10.4mg/20g/day of Sosokmyung-tang extract. The multiple parameter of global cerebral ischemia included the duration of coma of KCN(potassium cyanide)-injected(1.2mg/kg, i.v) group and the survival time of KCN-injected(3.0mg/kg, i.v) group. In the case of cerebral infarction by MCA occlusion, Sprague-Dawley rats were used and divided into three group at random. Control group was given nothing before MCA occlusion, experimental group was given 157.2mg/250g/day of Sosokrnyung-tang extract before MCA occlusion. We investigated edema and ischemic ratio in 8 slices of rats' brain after MCA occlusion. The results were obtained as follows : 1. Sosokrnyung-tang significantly shortened the duration of coma of KCN-injected(1.2mg/kg,i.v) group and lengthened the survival time of KCN-injected(3.0mg/kg, i.v) group. 2. Sosokmyung-tang significantly decreased cerebral edema and ischemic ratio in rats after MCA occlusion. From the above results, it was concluded that Sosokmyung-tang can be effectively applied to cerebrovascular diseases.

This study aims to understand the experiences of highly educated married immigrant women from China, who hold a master's degree or higher, when selecting an elementary school for their children and to explore the significance of that experience. This study included eight participants, all of whom were married immigrant women who had resided in Korea for a minimum of five years. Data was collected through in-depth interviews, which were conducted over approximately one year, from June 2022 to August 2023. The study was approached as a case study. As a result of this study, the similarities between the cases were "choices based on charactercentered education and cultural convergence", "choices for the child's future and career", and "choices influenced by the primary caregiver's use of bilingualism". The differences observed in the cases appeared in "choices based on the balance between global education ideals and economic realities", "choices based on specialized curriculum content", and "choices based on connections to higher-level schools". This study is important, as it underscores the need to conduct various research initiatives on multinational immigrant women and their children. These findings suggest that the study can contribute to the development of multicultural policies that are grounded in the actual experiences and critical awareness of married Chinese immigrant women, who constitute a substantial part of Korean society.

Water body detection using remote sensing based on machine interpretation of satellite image is efficient for managing water resource, drought and flood monitoring. In this study, water body detection with SAR satellite image based on machine learning was performed. However, non water body area can be misclassified to water body because of shadow effect or objects that have similar scattering characteristic comparing to water body, such as roads. To decrease misclassifying, 8 combination of morphology open filtered band, DEM band, curvature band and Cosmo-SkyMed SAR satellite image band about Mokpo region were trained to semantic segmentation machine learning models, respectively. For 8 case of machine learning models, global accuracy that is final test result was computed. Furthermore, concordance rate between landcover data of Mokpo region was calculated. In conclusion, combination of SAR satellite image, morphology open filtered band, DEM band and curvature band showed best result in global accuracy and concordance rate with landcover data. In that case, global accuracy was 95.07% and concordance rate with landcover data was 89.93%.

The purpose of this investigation is to analyze the synchronization between the representative global freight index, the Baltic Dry bulk Index (BDI) and the China Container Freight Index (CCFI) with monthly data from 2000 to 2016. Using the non-stationarity of the business cycle that is able to include common trends, we employ the Engle-Granger 2 stage co-integration test and found no synchronization. On the contrary, we additionally estimated the causality between the markets and revealed the causality, which implies that the Chinese economy has a significant effect on the global market. The results of this empirical analysis demonstrate that the CCFI of China is appropriate for analyzing the shipping industry. In practice, this means that it is more appropriate to include CCFI in the global market outlook than use it as a substitute for the global freight rate index, the BDI. This is a case study of the synchronization of the economic fluctuations of the shipping industry. It suggests that the economic fluctuations of China need to be considered in the unstable global market forecast. In particular, this case applies to the fluctuations in the shipping industry synchronism and provides important results in scientific terms.

The ecological process-based approach provides a detailed assessment of belowground compartment as one of the major compartment of carbon balance. Carbon net balance (NEP: net ecosystem production) in forest ecosystems by ecological process-based approach is determined by the balance between net primary production (NPP) of vegetation and heterotrophic respiration (HR) of soil (NEP=NPP-HR). Respiration due to soil heterotrophs is the difference between total soil respiration (SR) and root respiration (RR) (HR=SR-RR, NEP=NPP-(SR-RR)). If NEP is positive, it is a sink of carbon. This study assessed the forest carbon balance by ecological process-based approach included belowground compartment intensively. The case study in the Takayama Station, cool-temperate deciduous broad-leaved forest was reported. From the result, NEP was estimated approximately 1.2 t C $ha^{-1} yr^{-1}$ in 1996. Therefore, the study area as a whole was estimated to act as a sink of carbon. According to flux tower result, the net uptake rate of carbon was 1.1 t C $ha^{-1} yr^{-1}$.
