This paper presents a comprehensive survey of various artificial intelligence (AI) techniques implemented in cognitive radio engine to improve cognition capability in cognitive radio networks (CRNs). AI enables systems to solve problems by emulating human biological processes such as learning, reasoning, decision making, self-adaptation, self-organization, and self-stability. The use of AI techniques is studied in applications related to the major tasks of cognitive radio including spectrum sensing, spectrum sharing, spectrum mobility, and decision making regarding dynamic spectrum access, resource allocation, parameter adaptation, and optimization problem. The aim is to provide a single source as a survey paper to help researchers better understand the various implementations of AI approaches to different cognitive radio designs, as well as to refer interested readers to the recent AI research works done in CRNs.

BIM (Building Information Model/Modeling) is attracting attention not only as a unit technology, but also as a factor that can promote the transformation of the entire construction industry process. This study aims to investigate the status and cases of policy introduction and legalization of BIM in foreign countries for the advancement of their own construction industry, and to discover policy implications that can be applied to Korea. The first survey uncovered policy elements, and based on this, the second survey conducted an in-depth survey of experts in actual BIM service and research activities. Looking at each priority, BIM standardization, mandating BIM in projects, payment standard establishment, and PQ additional points were given the highest level of importance.

Side-channel attacks are a quiet mighty type of attack that targets specific physical implementations vulnerabilities. Even though several researchers have examined diverse means and methods of detecting side-channel attacks, at the present time a systematic review of these approaches does not exist. The purposes of this paper are to give an extensive analysis of literature on side-channel attack detection and offer intuitiveness from past research studies. In this study, a literature survey is conducted on articles related to side-channel attack detection between 2020 and 2022 from ACM and IEEE digital libraries. From the 10 publications included in the study, it appears they target either a single type of side-channel attacks or multiple types of side-channel attacks. Therefore, a vital review of each of the two categories is provided, as well as possible prospective research in this field of study.

Cloud computing is the latest approach that is developed for reducing the storage of space to store the data and helps the quick sharing of the data. An increase in the cloud computing users is observed that is also making the users be prone to hacker's attacks. To increase the efficiency of cloud storage encryption mechanisms are used. The encryption techniques that are discussed in this survey paper are searchable encryption, attribute-based, Identity-based encryption, homomorphic encryption, and cloud DES algorithms. There are several limitations and disadvantages of each of the given techniques and they are discussed in this survey paper. Techniques are found to be effective and they can increase the security of cloud storage systems.

Digital transformation is accelerating in all industries due to COVID-19 and rapidly developing ICT technology. In the field of education, teaching methods that combine various IT devices and software technologies are being applied. The education requires a future learning environment using EduTech such as digital learning tools. We perform a case study on the use of digital learning tools for effective class. In this study, digital learning tools were applied to an university class. The class was held in the second semester of 2022 at A university, with 67 students participating. In our case, QuizN, Mentimeter, and Google Forms were applied as digital learning tools. In order to evaluate our case, a survey was conducted using the Google Questionnaire. From the results of the survey evaluation, more than 85% of all survey questions answered that they were satisfied. From it, digital learning tools were shown to be effective in class operation.

Lately, there has been a notable surge in the defense industry's efforts to develop highly advanced intelligent systems. These systems encompass sophisticated computing platforms that boast an impressive level of autonomy. However, it's important to acknowledge that these very systems are not impervious to vulnerabilities stemming from both hardware and software tampering. Within the context of this discourse, our focus of the survey is directed towards the hardware security module. This component stands out for its capability to offer a significantly heightened level of protection when compared to conventional software-based techniques. Through the lens of this paper, we embark on a comprehensive survey of Trusted Platform Module (TPM), a hardware security module, shedding light on its potential to fortify the defense against threats that emerge from various vectors of attack.

본 연구에서는 국제연구협력관련 모든 정보유형을 발굴하고 각 유형별로 정보를 수집하여 데이터베이스로 구축하고자 하였다. 이를 위해 연구진이 메타데이터를 일차적으로 개발하고 메타데이터 전문가들과의 논의과정을 거쳐 1차적으로 메타데이터를 개발하였으며, 이에 대해 국제연구협력 관련 전문가들을 대상으로 설문조사를 수행하였다. 뿐만 아니라 각 정보원 유형별 메타필드에 데이터를 수집하여 입력하였으며, 메타필드별로 실제 데이터가 존재하는지 등의 과정을 거쳐 메타필드를 검증하였다. 본 연구에서 설계한 DB 유형은 국제연구협력정보원 DB, 국제연구협력 사업 DB, 국제연구협력 전문가 DB, 국제연구협력 기관 DB, 국제기구 DB, 기타 DB 등이며, 이에 대해 설문조사를 수행하고 실제 데이터를 입력하여 필드를 검증한 결과, 설문조사 결과와 필드별 데이터 입력률은 상당히 높은 일치율을 보였다. 다만 국제기구 데이터 필드만은 이용자의 높은 중요도 평가에도 불구하고 10%이하의 데이터 입력률을 보이는 필드가 25% 정도 있는 것으로 확인되었다.

Purpose: This study aims to investigate consumers' demand of and perspective on drug information domestically available and uncover hurdles that they faced while utilizing information. Methods: We conducted a survey of 101 consumers, face-to-face after obtaining informed consent. Chi-squared, or Fisher's exact tests, and multivariate logistic models were used to investigate the association between participants' perceptions and characteristics. Results: As results, participants showed the highest demand for "Adverse effects >90%"; "Drug interactions/Dosage/Drug-food interactions/Indication >80%", and utilized package inserts (52%), doctors (41%) and pharmacists (36%) most often as information sources. Generally, the most common difficulty consumers suffered with was that "it is hard to understand (51%)". With public sources of drug information, sixty one percent of participants were "unaware of the provision of information", resulting in strikingly low usage rates (5~11%). Subgroup analyses indicated that the older (${\geq}50$ years) and the disadvantaged might have been placed in the blind spot of information mostly developed online (p<0.05).Conclusion: In conclusion, public sources of drug information that have been developed online might fail to meet consumers' demand. Greater efforts should be made to balance the development of the information sources between online and offline, and to increase accessibility of the established information sources.
