This study was conducted to investigate the relationship between self-esteem, self-awareness, and empathy and to identify factors that influence empathy among 302 nursing students from a university in C city from March to May 2021. The collected data were subjected to t-test, ANOVA, correlation and multiple regression analysis. As a result of the study, empathy was 3.59 points out of 5, and gender and nursing department satisfaction were significantly different from empathy. The factors that had a significant effect on empathy were private self-awareness, public self-awareness, positive self-esteem, and gender, with the explanatory power of 22.9%. In order to increase the level of self-esteem, self-awareness and empathy for nursing students, it is necessary to establish a new curriculum that examines interest in their inner world. Development of various curriculum programs such as team classes that help promote interaction using small groups and role-playing classes that explore and experience one's own or others' thoughts and emotions are suggested.

Precise counting of cell number stands in important position within clinical and research laboratories. Conventional methods such as hemocytometer, migration/invasion assay, or automated cell counters have limited in analytical time, cost, and accuracy., which needs an alternative way with time-efficient in-situ approach to broaden the application avenue. Here, we present simple coding-based cell counting method using image analysis tool, freely available image software (ImageJ). Firstly, we encapsulated RFP-expressing bacteria in a droplet using microfluidic device and automatically performed fluorescence image-based analysis for the quantification of cell numbers. Also, time-lapse images were captured for tracking the change of cell numbers in a droplet containing different concentrations of antibiotics. This study confirms that our approach is approximately 15 times faster and provides more accurate number of cells in a droplet than the external analysis program method. We envision that it can be used to the development of high-throughput image-based cell counting analysis.

The meticulous figure painting is one of the wonders of traditional Chinese painting and has blossomed in art history with its unique and interesting style. The period from the Warring States period to the Song and Yuan dynasties was a glorious period in its history, after which it tended to decline due to changes in painting materials and many socio-historical reasons. The extensive cultural exchanges in the world today, the penetration of Western values and the expansion of information technology have brought a huge impact on Chinese meticulous figure painting, which has developed an active way of thinking and expression after absorbing certain elements of Western culture and thought on the basis of inherited tradition. Contemporary Realistic Figure painters continue to explore new developments in meticulous figure painting in the contemporary context, and give contemporary meticulous figure painting a new cultural and ideological connotation, forming a new look that meets the requirements of the times, with richer and more lively content, subject matter and formal language. Traditional meticulous figure painting is characterised by a highly refined use of line and coloring composition. Contemporary meticulous figure painting focuses on the use of purely formal language and the expression of the personality of the creative subject, with a new outlook on the world of painting.

Climate change and invasive alien plant species (IAPs) are having a significant impact on mountain ecosystems. The combination of climate change and socio-economic development is exacerbating the invasion of IAPs, which are a major threat to biodiversity loss and ecosystem functioning. Species distribution modelling has become an important tool in predicting the invasion or suitability probability under climate change based on occurrence data and environmental variables. MaxEnt modelling was applied to predict the current suitable distribution of most noxious weed A. adenophora (Spreng) R. King and H. Robinson and analysed the changes in distribution with the use of current (year 2000) environmental variables and future (year 2050) climatic scenarios consisting of 3 representative concentration pathways (RCP 2.6, RCP 4.5 and RCP 8.5) in Bhutan. Species occurrence data was collected from the region of interest along the road side using GPS handset. The model performance of both current and future climatic scenario was moderate in performance with mean temperature of wettest quarter being the most important variable that contributed in model fit. The study shows that current climatic condition favours the A. adenophora for its invasion and RCP 2.6 climatic scenario would promote aggression of invasion as compared to RCP 4.5 and RCP 8.5 climatic scenarios. This can lead to characterization of the species as preferring moderate change in climatic conditions to be invasive, while extreme conditions can inhibit its invasiveness. This study can serve as reference point for the conservation and management strategies in control of this species and further research.

The purpose of this study is to present implications by analyzing the Swiss Federal Court's annulment of the arbitration Awards in Court of Arbitration for Sport(CAS). As international interest in the sports sector increases, related disputes are also increasing. Therefore, the role of CAS specializing in sports disputes is becoming very important. In particular, the Swiss federal court's annulment of the arbitral awards made by the CAS could contribute significantly to the development of sports arbitration in the future. Looking at the case analyzed in this study, first of all, it is about the partiality of the arbitrator. The court judged that the arbitrator posted and shared racist articles on SNS, which could be sufficiently biased. Next, it is about the uncertainty of the arbitration clause. The arbitral award was finally canceled due to the issue of whether the CAS could make an arbitral award with jurisdiction over a clause that includes both dispute resolution through a sports organization and dispute handling in a national court. As a result of the analysis of this study, in the case of unclear arbitration provisions, it will be necessary to prepare an arbitration agreement. In addition, in the case of unclear arbitration provisions, it will be necessary to prepare a post-arbitration agreement. Finally, in order to revitalize sports arbitration, it will be necessary to train professional arbitrators in Korea, support them to work internationally, and establish specialized arbitration institutions.

There is a need for a technology that can quickly and accurately analyze soil carbon contents. Existing soil carbon analysis methods are cumbersome in terms of professional manpower requirements, time, and cost. It is against this background that the present study leverages the soil physical properties of color and water content levels to develop a model capable of predicting the carbon content of soil sample. To predict the total carbon content of soil, the RGB values, water content of the soil, and lux levels were analyzed and used as statistical data. However, when R, G, and B with high correlations were all included in a multiple regression analysis as independent variables, a high level of multicollinearity was noted and G was thus excluded from the model. The estimates showed that the estimation coefficients for all independent variables were statistically significant at a significance level of 1%. The elastic values of R and B for the soil carbon content, which are of major interest in this study, were -2.90 and 1.47, respectively, showing that a 1% increase in the R value was correlated with a 2.90% decrease in the carbon content, whereas a 1% increase in the B value tallied with a 1.47% increase in the carbon content. Coefficient of determination (R²), root mean square error (RMSE), and mean absolute percentage error (MAPE) methods were used for regression verification, and calibration samples showed higher accuracy than the validation samples in terms of R² and MAPE.

In the architectural space, the user's behavior is the most important factor in evaluating the quality of architecture. Normally, the evaluation of user behavioral performance was carried out after a building was completed. Recently, interest in and efforts at pre-simulation based on information technology are accelerating. However, since existing user simulation technology is concerned mainly with simply escaping from a large space, it is impossible to simulate the behavior of multiple users in an architectural space. The present study strives to develop a human-figured intelligent agent for advanced user simulation based on ontology. The main purpose of the study is to employ the intelligent behaviors of a NPC(Non-player Character) to infer the ontology of both spatial and user information. In this paper, we intend to integrate ontology inference technology into the virtual space. And also, this study suggest the ontology visualization technology which illustrate the ontology-based information and their change in the spatial information.

The surge in the oil prices, increasing global population, climate change, and waste management problems are the major issues which have led to the development of biofuels from lignocellulosic wastes. Cellulosic or second generation (2G) bioethanol is produced from lignocellulosic biomass via pretreatment, hydrolysis, and fermentation. Pretreatment of lignocellulose is of considerable interest due to its influence on the technical, economic and environmental sustainability of cellulosic ethanol production. In this study, furniture waste sawdust was subjected to alkaline peroxide (H₂O₂) for the production of reducing sugars. Sawdust was pretreated at different concentrations from 1-3% H₂O₂ (v/v) loadings at a pH of 11.5 for a residence time of 15-240 min at 50, 75 and 90 ℃. Optimum pretreatment conditions, such as time of reaction, operating temperature, and concentration of H₂O₂, were varied and evaluated on the basis of the amount of total reducing sugars produced. It was found that the changes in the amount of lignin directly affected the yield of reducing sugars. A maximum of 50% reduction in the lignin composition was obtained, which yielded a maximum of 75.3% total reducing sugars yield and 3.76 g/L of glucose. At optimum pretreatment conditions of 2% H₂O₂ loading at 75 ℃ for 150 min, 3.46 g/L glucose concentration with a 69.26% total reducing sugars yield was obtained after 48 hr. of the hydrolysis process. Pretreatment resulted in lowering of crystallinity and distortion of the sawdust after the pretreatment, which was further confirmed by XRD and SEM results.
