Purpose: The study examines changes in students' self-assessment of their general communication (GC) and medical communication (MC) competencies, as well as perceptions of MC concepts. Methods: Participants included 108 second year medical students enrolled at a Korean medical school studying an MC curriculum. It was divided into three sections, and participants responded to questionnaires before and after completing each section. To assess perceived GC and MC competency, items based on a 7-point Likert scale were employed; a single open-ended item was used to examine students' perceptions of MC. Statistical analysis was conducted to gauge GC and MC competency, whereas semantic network analysis was used to investigate students' perceptions of MC. Results: Students perceived their GC competency to be higher than MC. Perceived MC competency differed significantly across the three sections, whereas no differences were found for GC. There were no statistically significant differences after completing the curriculum's second and third sections; however, the vocabulary students used to describe MC concepts became more scholarly and professional. In the semantic networks, the link structure between MC-related words decreased in linearity and looseness, becoming more complex and clustered. The words 'information' and 'transfer' proved integral to students' perceptions; likewise, 'empathy' and 'communication' became closely connected in a single community from two independent communities. Conclusion: This study differed from prior research by conducting an in-depth analysis of changes in students' perceptions of MC, and its findings can be used to guide curriculum development.

The explosive growth of video-based services is considered as the dominant contributor to Internet traffic. Hence it is very important for video service providers to meet the quality expectations of end-users. In the past, the Quality of Service (QoS) was the key performance of networks but it considers only the network performances (e.g., bandwidth, delay, packet loss rate) which fail to give an indication of the satisfaction of users. Therefore, Quality of Experience (QoE) may allow content servers to be smarter and more efficient. This work is motivated by the inherent relationship between the QoE and the QoS. We present a no-reference (NR) prediction model based on Deep Neural Network (DNN) to predict video QoE. The DNN-based model shows a high correlation between the objective QoE measurement and QoE prediction. The performance of the proposed model was also evaluated and compared with other types of neural network architectures, and three known machine learning methodologies, the performance comparison shows that the proposed model appears as a promising way to solve the problems.

Purpose: This study aimed to identify factors associated with the self-rated health of married immigrant women in South Korea. Methods: Data, collected in August 2018, were derived from the 2018 National Multicultural Family Survey. Study subjects were 9,230 married immigrant women. Data were analyzed using logistic regression. Results: Of the study subjects, 23.2% rated their health as poor. Results showed that individual factors (age, ethnic affiliation, duration in South Korea, and depressive symptoms); social and community networks (relationship with spouse, parenting efficacy, Korean proficiency, perceived discrimination, social support, and social activities); and living and working conditions (life satisfaction and unmet heath needs) were associated with health. Married immigrant women in their 50s or older, living in Korea for more than 15 years, experiencing depressive symptoms, low life satisfaction, and having unmet health needs were especially at high risk of poor health. Conclusion: More detailed health policy that considers age, length of stay, and country of origin. To prevent the rapidly deteriorating health of married immigrant women after middle age, mental health support should be given priority, and systematic improvement is needed to increase accessibility healthcare services.

Purpose: This study aimed to identify factors affecting the mental health status of children from multicultural families in South Korea. Methods: This study was based on Dahlgren and Whitehead's (1991) rainbow model as a conceptual framework and used data from the second phase of the multicultural adolescents panel study conducted by the National Youth Policy Institute. Multiple logistic regression analysis was performed using SPSS version 26.0, with p<.05 considered to indicate statistical significance. Results: In the final model, stress (odds ratio [OR]=0.53, p<.001), life satisfaction (OR=2.09, p=.004), self-esteem (OR=1.73, p=.032), and peer support (OR=1.46, p=.019) affected the mental health status of children from multicultural families. The living and working conditions and general socioeconomic, cultural, and environmental conditions did not significantly influence the mental health status of children from multicultural families in the final model. Conclusion: As components of Dahlgren and Whitehead's model, individual hereditary and lifestyle factors, as well as social and community networks, affected the mental health status of children from multicultural families. Therefore, in order to improve the mental health of children from multicultural families, efforts are needed to alleviate their stress, increase life satisfaction and self-esteem, and strengthen their social support.

The field of land surveying is changing dramatically due to the way data is processed, analyzed and presented. Also, there is a growing demand for digital spatial information, coming primarily from the GIS (Geographical Information System) user community. Such a demand has created a strong development potential for a new land surveying software. An overview of the development and capabilities of a land surveying software platform based on the Windows system, SurveyingMap, is presented. Among its many features, SurveyingMap provides a lot of adaptability for networks adjustment, geodetic and plane coordinates transformation, contouring, sectioning, DTM (Digital Terrain Model) generation, and large scale mapping applications. The system output is compatible with well known computer aided drafting (CAD) /GIS packages to expand its scope of applications. SurveyingMap is also suitable for non-technical users due to the user-friendly graphic user interface. The system could be used in engineering, architecture, GIS, and academic teaching and research, among other fields. Two applications of SurveyingMap, extension of field control and large scale mapping, for the case study area are established. The results demonstrate that the system is adaptable and reasonably priced for use by college and university students.

To investigate the short-run effects of social capital on migration decisions of individuals in the rural areas of Vietnam, we conducted dataset mining and performed regression model analysis in the form of panel data. As control variables, we employed the variable of social capital, which is measured by an individual's network, as well as demographic characteristics of individuals and households. We discovered that when a household is in financial distress, social networks such as linkages or asking for aid from others often enhance individual capacity. Individuals with a large social network outside of their immediate area are more inclined to relocate to the location where their connectors live. Individual participation and degree of participation in the organizational community, on the other hand, have little bearing on the likelihood of migration. In addition, this research examines theories and empirical research on the relationship between social capital and migration. Based on our research findings, we have recommended some measures to boost the efficiency of social capital and migration in rural areas of Vietnam through local government solutions.

Water distribution networks (WDNs) are designed to satisfy water requirement of an urban community. One of the central issues in human history is providing sufficient quality and quantity of water through WDNs. A WDN consists of a great number of pipelines with different ages, lengths, materials, and sizes in varying degrees of deterioration. The available annual budget for rehabilitation of these infrastructures only covers part of the network; thus it is important to manage the limited budget in the most cost-effective manner. In this study, a novel pipe replacement scheduling approach is proposed in order to smooth the annual investment time series based on a life cycle cost assessment. The proposed approach is applied to a real WDN currently operating in South Korea. The proposed scheduling plan considers both the annual budget limitation and the optimum investment on pipes' useful life. A non-dominated sorting genetic algorithm is used to solve a multi-objective optimization problem. Three decision-making objectives, including the minimum imposed LCC of the network, the minimum standard deviation of annual cost, and the minimum average age of the network, are considered to find optimal pipe replacement planning over long-term time period. The results indicate that the proposed scheduling structure provides efficient and cost-effective rehabilitation management of water network with consistent annual budget.

As the aging society continues in recent years, interest in dementia is increasing. Among them, Alzheimer's disease is a degenerative brain disease that accounts for the largest percentage of all dementia patients, with the medical community currently not offering clear prevention and treatment for Alzheimer's disease, and the importance of early treatment and early prevention is emphasized. In this paper, we intend to find the most efficient activation function by combining various activation functions centering on convolutional neural networks using MRI datasets of normal people and patients with Alzheimer's disease. In addition, it is intended to be used as a dementia classification modeling suitable for the medical field in the future through Alzheimer's dementia classification modeling.

This article is about the emergence of Islamic modernism among Cham Muslim communities in Cambodia and Cochinchina during the early 20th century. Based on a combined critical reading of existing scholarship, historicized first-hand anthropological accounts, as well as archival sources from the National Archives of Cambodia and the Vietnam National Archives II, it argues accounts of modernists in these sources were either (1) cast through a French colonial reading of a Buddhist state lens and (2) cast through a Malay lens, based upon the Kaum Muda/Kaum Tua divide. First, it proceeds with a historical explanation of the emergence of Islam and the discourse used to describe Muslim communities in Vietnamese, French, and Cham language sources. Then, it turns the narrative toward an examination of the emergence of the "Kaum Muda" or "New Group" of reformist-minded modernist Muslims in early 20th century Cambodia. Delineating the networks of these intellectuals as they stretched across the border through Cochinchina, also highlights a pre-existing transnational element to the community, one that well predates current discussions of twenty-first-century transnationalism. Through a combination of the study of multiple language sources and historical methods, the article highlights the importance of polylingualism in the study of the history of Muslims in Southeast Asia.
