  • Purpose: South Korea has expanded its accelerated second-degree Bachelor of Science in Nursing program to resolve its supply-demand imbalance in nursing, although how these students are adapting to and performing in college after admission remains unclear. Therefore, this study aimed to conduct an in-depth exploration of how Korean accelerated second-degree Bachelor of Science nursing students interact with society and adapt to college life for establishing further supportive educational policies and programs. Methods: Participants comprised 20 South Korean accelerated second-degree Bachelor of Science in Nursing students. The data were collected via online or offline in-depth interviews and analyzed using Strauss and Corbin's grounded theory and by applying a constant comparative method to achieve theoretical saturation. Results: The core category, derived using open, axial, and selective coding, was "process of the uncharted journey toward a new dream." The participants' college adaptation processes were found to involve three phases: trial and error, adjustment, and acceptance and integration. Conclusion: These findings can be used to develop, apply, test, and improve various support programs for accelerated second-degree Bachelor of Science in Nursing students and to advance the nursing profession by nurturing a workforce with diverse academic backgrounds and faster college life adaptation.

  • The paper investigates the process of pulsation of a spherical cavity (bubble) in a liquid under the influence of a source of ultrasonic vibrations. The process of pulsation of a cavitation pocket in liquid is investigated. The Kirkwood-Bethe model was used to describe the motion. A numerical solution algorithm based on the Runge-Kutta-Felberg method of 4-5th order with adaptive selection of the integration step has been developed and implemented. It was revealed that if the initial bubble radius exceeds a certain value, then the bubble will perform several pulsations until the moment of collapse. The same applies to the case of exceeding the amplitude of ultrasonic vibrations of a certain value. The proposed algorithm makes it possible to fully describe the process of cavitation pulsations, to carry out comprehensive parametric studies and to evaluate the influence of various process parameters on the intensity of cavitation.

  • In this study MD simulations have been performed to observe the behavior of a grain boundary in an a-Fe plate under 2-dimensional loading. In MD simulation the acceleration of every molecule can be achieved from the potential energy and the force interacting between each molecule and the integration of the motion equation by using Verlet method gives the displacement of each molecule. Initially four a-Fe rectangular plates having different misorientation angles of grain boundary were modeled by using the Johnson potential and Morse potential We compared the potential energy of the grain boundary system with that of the perfect structure model. Also we could obtain the width of the grain boundary by investigating the local potential energy distribution. The tensile loading for each grain boundary models was applied and the behavior of grin boundary was studied. From this study it was clarified that in the case using Johnson potential the obvious fracture mechanism occurs along the grain boundary in the case of Morse potential the diffusion of the grain boundary appears instead of the grain boundary fracture.

  • The NDVI(normalized difference vegetation index) dataset is unique or main tool to assess the global, multi seasonal, multi annual, and multi spectral changes over the World. These features are useful for environmental studies in particular, for the vegetation coverage monitoring of the country as Mongolia, where are large pastureland and pastoral animal husbandry, which dependent on natural conditions. Pasture vegetation cover is changing accordingly with both of global climate change and anthropogenic effect or human impacts. Using past 20 years (1982-2001) NDVI derived from NOAA satellite, its dynamical trend has been decreased in all natural zones differently. Also applied the method named "Two Years Differences" which could calculate the number of years with increased or decreased NDVI values at the same place. From May to September have occurred the 9 years maximum decreases of NDVI over Mongolia, but it obtained differently in spatial and temporal scale. In 24.4 ? 32.7% of all territory occurred one year decrease of NDVI and in 18% occurred more than 3 years frequent decrease of NDVI. According to the linear trend of NDVI and in 18% occurred more than 3 years frequent decrease of NDVI dynamics over 69% of whole territory of Mongolia NDVI values had been decreased due to both natural and human induced impacts to the pasture condition. In this paper also included some results of the integrated analyses of NOAA/NDVI and ground truth data over Monglia separately by natural zones.

  • Community portraits can deeply explore the characteristics of community structures and describe the personalized knowledge needs of community users, which is of great practical significance for improving community recommendation services, as well as the accuracy of resource push. The current community portraits generally have the problems of weak perception of interest characteristics and low degree of integration of topic information. To resolve this problem, the reader community portrait method based on the thematic and timeliness characteristics of interest labels (UIT) is proposed. First, community opinion leaders are identified based on multi-feature calculations, and then the topic features of their texts are identified based on the LDA topic model. On this basis, a semantic mapping including "reader community-opinion leader-text content" was established. Second, the readers' interest similarity of the labels was dynamically updated, and two kinds of tag parameters were integrated, namely, the intensity of interest labels and the stability of interest labels. Finally, the similarity distance between the opinion leader and the topic of interest was calculated to obtain the dynamic interest set of the opinion leaders. Experimental analysis was conducted on real data from the Douban reading community. The experimental results show that the UIT has the highest average F value (0.551) compared to the state-of-the-art approaches, which indicates that the UIT has better performance in the smooth time dimension.

  • Purpose: This study developed a structural model for explaining and predicting terminal care performance in long-term care hospital nurses. The model was based on the stress integration model of Ivancevich and Matteson(1980) and the results of previous studies. Method: Data was obtained from August to September 2022 from 267 nurses in 13 long-term care hospitals in G-do. Results: Results of model verification for this study, revealed that factors directly affecting the terminal care performance of long-term care hospital nurses were nursing work environment(β=0.43, p<0.001), death anxiety(β=-0.29, p<0.001), and terminal care stress(β=0.22, p=0.003). However, the attitude toward nursing care of dying(β=0.07, p=0.287) had no effect on the terminal care performance. Conclusion: The results of this study, confirmed the necessity of improving an individual's perceived nursing work environment, continuous education related to terminal care to reduce death anxiety, and an interventional approach for enhancing terminal care performance.

  • Implementing a rural revitalization strategy will help spread traditional culture and promote the sustainable development of traditional handicrafts. Batik is a traditional handicraft made by residents in China's minority areas in their daily lives. This study was conducted because of a lack of objective methods for evaluating related project plans. This study was conducted to develop an index for the sustainable development of functional traditional batik production. This study had three major parts. The first part was a literature review that investigated sustainable and traditional batik dyeing and a field investigation carried out in Shitou Village, Danzhai County and Danzhai Paimo Village, Anshun, Guizhou to identify the factors that influence traditional batik production. The second part identified the factors identified in previous research that affect sustainable, traditional batik production and the projects executed to do the same. The third part was a survey conducted using the Delphi method. The results were analyzed, producing 10 influencing and 23 detailed factors that affect traditional batik production. Future research in this area should draw on various disciplines, investigate the direction in which traditional batik production is developing, and determine how to promote the sustainable development of other traditional handicrafts.

  • Small-film-type ion sensors are garnering considerable interest in the fields of wearable healthcare and home-based monitoring systems. The performance of these sensors primarily relies on electrode capacitance, often employing nanocomposite materials composed of nano- and sub-micrometer particles. Traditional techniques for enhancing capacitance involve the creation of nanoparticles on film electrodes, which require cost-intensive and complex chemical synthesis processes, followed by additional coating optimization. In this study, we introduce a simple one-step electrochemical method for fabricating gold nanoparticles on a carbon nanotube (Au NP-CNT) electrode surface through cyclic voltammetry deposition. Furthermore, we assess the improvement in capacitance by distinguishing between the electrical double-layer capacitance and diffusion-controlled capacitance, thereby clarifying the principles underpinning the material design. The Au NP-CNT electrode maintains its stability and sensitivity for up to 50 d, signifying its potential for advanced ion sensing. Additionally, integration with a mobile wireless data system highlights the versatility of the sensor for health applications.

  • Purpose: To investigate the intensity of bilateral international trade of the Silk Road Economic Belt (SREB) countries with Kazakhstan, its relationship with logistics (LPI), to assess their contribution to economic growth and distribution of commodity flows. Research design, data, and methodology: The method of analyzing the bilateral trade flow was applied by using the trade intensity index (TII) and a multidimensional regression model describing the relationship between LPI and its components, TII, the volume of exports and imports, GDP. Results: The nature and directions of the relationship between TII and the key components of logistics, the positive impact of LPI on the intensity of trade are established. It is revealed that the intensity of trade between the countries in the direction of the EAEU-Kazakhstan has a greater impact on the growth of LPI than in the opposite direction. At the same time, the higher the level of trade integration and the volume of GDP, the stronger their impact on the efficiency of logistics and distribution of commodity flows. Conclusions: Effective distribution of commodity flows will require the development of logistics components based on the direction of bilateral trade and the size of countries, the intensification of state reforms in the field of international trade and distribution logistics.
