Building on the framework of language socialization [10] in language learning and use, the present study examines the environmental factors involved in four college students' English learning in the situated place of the home during the COVID-19 pandemic. Using narrative inquiry, this study implements a time-series analysis to investigate undergraduates' online English learning in a rural area of northwest China. The data were collected via oral and written narration, semi-structured interviews, and class documents. Leveraging the field-habitus theories, the findings reveal that each of the students had a different habitus in the family field that influenced their English learning at home between March to July of 2020. Ultimately, all four students felt that their habitus made their online English learning ineffective and expressed that they did not wish to continue learning at home. The findings imply that it is important for rural parents to pay more attention to building college students' learning environments and helping students cultivate a strong learning habitus in the family field in northwest China.

This study sought to determine whether there were mediating effects on both mental health and sleep problems as induced by COVID-19 fears and its effects on preventive practices. The participants were 310 adults living in the Seoul/Gyeonggi Province. For data collection, an online survey was conducted using a semi-structured questionnaire. The collected data were analyzed using PROCESS Macro (Model 6) to validate the dual mediating effects. This study analyzed the direct effects of COVID-19 fears on the mental health problems, sleep problems and preventive practices. Both mental health and sleep problems had dual mediating effects in the influence of COVID-19 fears on preventive practices. Preventive practice has shown that the mediated effects of mental health problems play a strong role in instances when COVID-19 fears increase.

The purpose of this paper was to confirm the operational level of the military department of universities, which plays a key role in the officer training process, through empirical research and confirm meaningful results for improvement. There are 11 university military departments operated through the Army, agreements, and semi-agreement, and the Data Envelopment Analysis (DEA) was applied from the perspective of resource input and performance for each university's military department operation to analyze relative efficiency and confirm specific directions for improvement. As a result of operational efficiency analysis, 6 DMUs (Decsision Making Unit) were found to be efficient in the BCC model out of 11 DMUs, and the evaluation results could be confirmed through classification of efficient and inefficient groups through data capture analysis. This paper may be of practical value in that it checks the efficiency of the comparative university military departments and confirms specific information for development through the DEA-Additive model that reflects several evaluation factors at once. Through this, the operators of each university's military department are admitted.

Purpose: The purpose of this study was to explore practice-based evidence for health promotion in vulnerable populations with hypertension in primary health care settings. Methods: Two methodological procedures were adopted for this triangulation study. In the first phase, the sample was obtained from the computerized clinical data repository of a community nursing center. A total of 286 clients were assessed for hypertension as an actual circulation problem as coded in the Omaha System. In the second phase, a qualitative focus group was surveyed through semi-structured interviews conducted by nine advanced practice nurses who had been serving the hypertensive patients. Results: The community nurses provided essential primary healthcare services including health teaching guidance and counseling, and surveillance to vulnerable populations living in medically underserved community. There was a significant positive correlation between knowledge and behavior (r=.53, p<.01), between knowledge and health status (r=.40, p<.05), and between behavior and health status (r=.48, p<.01). Conclusion: This triangulation study encompassed not only quantitative findings from the computerized records of clients but also other information acquired from advanced practice nurses. This study contributes to understanding the importance of health promotion nursing interventions even with populations already diagnosed with chronic diseases such as hypertension.

In this study, the experiments for surface enhancement of silver mirror substrates were done, where we checked the characteristics of silver surface made by Tollen's and ${\gamma}$- irradiation method. The surface enhancement of Indigo carmine was analyzed by silver mirror and silver sol surfaces. The assignments of the vibrational bands shown in SERS spectra are given based on both literature and the semi-empirical calculations at the PM3 methods. We deduced that the adsorption orientation of Indigo carmine was little tilted perpendicular to the silver surfaces by using of the surface selection rules.

In this letter, a new dual-port Multiple-Input Multiple-Output (MIMO) antenna is introduced which has two independent signal feeding ports in a single antenna element to achieve smaller antenna volumes for the 5G mobile applications. The dual-port structure is implemented by adding a cross coupled semi-loop (CCSL) antenna as the secondary radiator to the ground short of inverted-F antenna (IFA). It is found that the port to port isolation is not deteriorated when an IFA and CCSL is combined to form a dual-port structure. The isolation property of the proposed antenna is compared with a polarization diversity based dual-port antenna proposed in the literature [9]. The operating frequency range is 3.3-4.0 GHz which is suitable for places where $4{\times}4$ MIMO systems are supposed to be deployed such as in China, EU, Korea and Japan at the band ${\times}$ (3.3 - 3.8GHz. The measured 6-dB impedance bandwidths of the proposed antennas are larger than 700 MHz with isolation between the feeding ports higher than 18 dB [1-2]. The simulation and measurement results show that the proposed antenna concept is a very promising alternative for 5G mobile applications.

In this paper, the visual tracking system for arbitrary shaped moving object is proposed. The established tracking system can be divided into model based method that needs previous model for target object and image based method that uses image feature. In the model based method, the reliable tracking is possible, but simplification of the shape is necessary and the application is restricted to definite target mod el. On the other hand, in the image based method, the process speed can be increased, but the shape information is lost and the tracking system is sensitive to image noise. The proposed tracking system is composed of the extraction process that recognizes the existence of moving object and tracking process that extracts dynamic characteristics and shape information of the target objects. Specially, active contour model is used to effectively track the object that is undergoing shape change. In initializatio n process of the contour model, the semi-automatic operation can be avoided and the convergence speed of the contour can be increased by the proposed effective initialization method. Also, for the efficient solution of the correspondence problem in multiple objects tracking, the variation function that uses the variation of position structure in image frame and snake energy level is proposed. In order to verify the validity and effectiveness of the proposed tracking system, real time tracking experiment for multiple moving objects is implemented.
