In this presentation, noise control materials will be discussed from several points-of-view. First, materials will be categorized in terms of their intended function: i.e., as dissipative materials, as barriers, and as media intended to modify some aspect of the sound field. Within each category, example implementations will be described as will modeling procedures. In the context of barrier materials, recent developments in the area of metamaterials will be described briefly, and problems with some recently suggested approaches will be highlighted. Acoustical cloaking will be described as a method of modifying a sound field in such a way that a sensitive area is shielded from noise exposure; the practical difficulties of this approach will also be described. Finally, within each category of material and approach, a series of suggested research challenges will be described.

Around the world, there are increasing efforts underway to decarbonize the electricity generation system to mitigate the environmental impacts including climate change. While Indonesia has a huge potential for new and renewable energy, particularly solar photovoltaic, Indonesia has been largely dependent on fossil fuels. As of 2017, the installed capacity for solar photovoltaic in Indonesia was 78.5MW and this was only 0.04% of the theoretical solar potential, which is around 207.9GW($4.8kWh/m^2/day$). With the case of solar photovoltaic, this paper examined the reasons of low adoption of the technology and the challenges of energy transition in Indonesia from the policy and institutional perspectives.

Multilingual Knowledge Graphs (MKGs) have emerged as a crucial component in various natural language processing tasks, enabling efficient representation and utilization of structured knowledge across multiple languages. One can get data, information, and knowledge from various sectors, like libraries, archives, institutional repositories, etc. Variable quality of metadata, multilingualism, and semantic diversity make it a challenge to create a digital library and multilingual search facility. To accept these challenges, there is a need to design a framework to integrate various structured and unstructured data sources for integration, unification, and sharing databases. These are controlled using linked data and semantic web approaches. In future, multilingual knowledge graph overcomes all the linguistic nuances, technical barriers like semantic interoperability, data harmonization etc and enhance cooperation and collaboration throughout the world. Through a comprehensive analysis of the current state-of-the-art techniques and ongoing research efforts, this paper aims to offer insights into the future directions and potential advancements in the field of Multilingual Knowledge Graphs. This paper deals with a multilingual knowledge graph and how to build up a multilingual knowledge graph. It also focuses on the various challenges and opportunities for designing multilingual knowledge graphs.

Prevalence of Agile methods in software companies is increasing dramatically. Software companies need to employ these methods to overcome the inherent challenges of traditional methods. However, transitioning to Agile approach is a topic of debate and there is no unique and well-defined transition model or framework yet. Although some research studies have addressed barriers and strengths behind the successful Agile deployment, it seems that this process still needs to be studied more in depth. The rationale behind this is the socio-technical nature of Agile transition and adoption. Particularly, the challenges and problems that software companies are facing during Agile transition, show that this process in more difficult than expected. Conducting a large-scale research study revealed that Agile transition and adoption process needs to be supported by several critical prerequisites. This study adopted a Ground Theory with the participation of 49 Agile experts from 13 different countries and empirically identified seven transition prerequisites. These prerequisites focus on the different aspects of the transition. The main aim of this paper is proposing these prerequisites and theoretical and practical implication of these prerequisites. Providing these prerequisites before moving to Agile increases chance of success in Agile transition and adoption and leads to fewer challenges during the change process.

This study examines the cost and benefit (i.e., income) of the Forest Stewardship Council (FSC) rubber plantations in Thailand. The study attempts to identify the challenges to the implementation of FSC standards in rubber plantations in the country. A total of 60 rubber farmers in two Southern provinces, namely, Songkhla and Rayong, were interviewed through a standardized questionnaire to gather primary data. The study found that small-, medium- and large-sized FSC rubber plantations were worth investing in. All sizes of rubber plantations had similar values of benefit cost ratio (BCR). It was also found that the values of the discount payback period (DPP) of the three forms of FSC rubber plantations were 9-12 years, while the large rubber plantations had the highest internal rate of return (IRR) (19.0%). It implies that the large-size plantations had the highest values. The rubber farmers in the study area reported that they are facing a number of problems and hardships in implementing FSC standards, lacking knowledge and understanding of FSC, especially for preparing documentation. Therefore, the Thai government should take proper policy initiatives to remove all the problems and barriers in implementing FSC standards for the sustainable rubber production in the country.

In today's financial industry, Fintech (financial technology) has showed its role of an innovation-driving area, which can bring outstanding changes to the traditional financial market. This article will briefly introduce Fintech as well as its development in Vietnam. Besides, the research also provided a survey on experts' opinions on the challenges to the promotion of Fintech application for the modernization of the banking-finance system in Vietnam. The survey results of 40 experts in banking with knowledge of Fintech identify five challenges faced by Fintech companies in Vietnam: (1) legal corridor; (2) infrastructure; (3) Fintech companies; (4) customers; and (5) human resources. From these five challenges/barriers, there are 14 detailed aspects. The results of the expert survey using descriptive statistics show that all five factors are assessed to be low and need to be better addressed in the future. The authors suggest several solutions for further development of Fintech to support the modernization of the banking-finance system in Vietnam: (1) quickly complete the regulatory framework; (2) introduce policies on tax exemption; (3) promote research and application of the benefits of block-chain technology; (4) utilize the abilities of the human resources; and (5) actively promote and popularize knowledge about Fintech.

Purpose: In Korea, since the Act on Hospice and Palliative Care and Decisions on Life-Sustaining Treatment for Patients at the End of Life was implemented in February 2018, advance directives (ADs) have become legally effective and should be documented after sufficient explanation by a registered counselor. However, little is known regarding the adequacy of current AD counseling. This qualitative study aimed to explore the barriers to AD counseling based on counselors' experiences. Methods: We conducted focus group interviews using purposive sampling. Seven counselors working at hospitals, community health institutions, and non-profit organizations participated in this study. They were asked about the challenges and problems they encountered during AD counseling. Results: Three themes emerged from this study; 1) issues regarding consistency in AD counseling, 2) issues regarding AD counselors' competency and work environment, and 3) issues regarding the adequacy of the service system. The interviewees stated that the lack of a manual for standardized service made AD counseling inconsistent. The limited competency and poor work environment of counselors were pointed out as major barriers. The interviewees also stated that a proper service system considering individual circumstances is absent. Conclusion: The goals of AD counseling should be clarified and guidance should be implemented for providing standardized services. Further efforts to enhance the competency of AD counselors and to improve their working conditions are needed. Establishing an integrated framework for an adequate service system is also essential to overcome systematic barriers to AD counseling.

Purpose: The current challenges faced by nurses in providing high quality and evidence-based practice (EBP) supported care require profound changes in nursing education. To understand the changes needed to strengthen EBP education, the researchers examined EBP self-efficacy, course needs, barriers, and facilitators for academic faculty and clinical nurse preceptors to teach EBP in undergraduate nursing curricula. Methods: For this study, mixed-method approach was used with survey data collected from 73 academic faculty members from 54 universities. Further, 17 clinical nurse preceptors in three academic hospitals provided qualitative data for exploration of barriers and facilitators to teaching EBP. Data analysis used SPSS/WIN 21.0 and content analysis. Results: Quantitative data showed that although the overall level of self-efficacy among faculty was moderate, the implementation levels were relatively low. Most faculty members agreed with the need to integrate EBP courses into undergraduate nursing curricula. The qualitative data showed that the barriers to teaching EBP were lack of knowledge, skill, and initial investment for teaching EBP; hierarchical, rules-oriented nursing culture; potential learner overloads in processing EBP; limited research dissemination and application. Facilitators were identified as the importance of EBP to the profession of nursing; collaboration in schools and hospitals; and continuing education in teaching/utilizing EBP. Conclusion: The findings indicate that for successful integration of EBP ni nursing education there is a need for faculty training and integrated EBP courses.
