Drone remote identification (ID) capability is essential to ensure public safety, help law enforcement, and secure the safety and efficiency of the national airspace. Remote ID technology can be used to differentiate compliant drones from illegal drones that pose a potential security risk by providing airspace awareness to the civil aviation agency and law enforcement entities. In addition, the increased safety and efficiency obtained by mandating remote ID will make it possible to operate drones over populated areas and beyond visual lines of sight. In addition, remote ID will allow drones to be safely integrated into unmanned traffic management systems and the national airspace. Remote ID devices can be categorized by type, i.e., broadcast remote ID or network remote ID. The broadcast remote ID, which has high technical maturity and will be applied in the near future, is primarily considered to ensure the security of drones. The network remote ID, which is being developed and tested and will be applied in the distant future, can be used additionally to ensure the safety and the efficiency of the national airspace. In this paper, we analyze the trends on regulation and standardization activities for drone remote ID primarily in the United State and Europe.

Purpose: Topic modeling is a text mining technique that extracts concepts from textual data and uncovers semantic structures and potential knowledge frameworks within context. This study aimed to identify major keywords and network structures for each major topic to discern research trends in women's health nursing published in the Korean Journal of Women Health Nursing (KJWHN) using text network analysis and topic modeling. Methods: The study targeted papers with English abstracts among 373 articles published in KJWHN from January 2011 to December 2021. Text network analysis and topic modeling were employed, and the analysis consisted of five steps: (1) data collection, (2) word extraction and refinement, (3) extraction of keywords and creation of networks, (4) network centrality analysis and key topic selection, and (5) topic modeling. Results: Six major keywords, each corresponding to a topic, were extracted through topic modeling analysis: "gynecologic neoplasms," "menopausal health," "health behavior," "infertility," "women's health in transition," and "nursing education for women." Conclusion: The latent topics from the target studies primarily focused on the health of women across all age groups. Research related to women's health is evolving with changing times and warrants further progress in the future. Future research on women's health nursing should explore various topics that reflect changes in social trends, and research methods should be diversified accordingly.

전 세계적으로 유례없는 Covid-19 팬데믹으로 인해 기업의 비즈니스 방식 및 내용이 크게 변화됐다. 따라서 Covid-19 이후 산업 전반에서 일어나고 있는 혁신 양상을 면밀히 모니터링하고, 이를 바탕으로 미래 비즈니스를 기획/설계하는 것이 산업현장에서 크게 요구되고 있다. 다수 연구에서 펜데믹 이후 비즈니스 동향 분석이 시도됐으나 특정 산업에 국한된 분석을 수행하는 점, 설문 및 문헌 연구 중심으로 수행되어 객관적 데이터의 활용이 부족한 점에서 한계점이 존재하고 있다. 이에 본 연구에서는 글로벌 스타트업 데이터인 Crunchbase를 활용하여 Covid-19 이후 비즈니스 산업의 트렌드를 분석하고자 한다. 트렌드 분석을 위해 Crunchbase에서 2018년부터 2021년까지 2년 단위로 데이터를 수집 및 전처리를 진행하였다. 산업 변화를 확인하기 위해 네트워크 분석, LDA 기반 토픽 분석, Doc2vec 클러스터링 분석을 결합한 접근 방식을 사용하여 비즈니스 콘텐츠의 변화를 분석하였다. 연구 결과 각 분야에서 비대면/온라인 기술들이 훨씬 전문성을 갖추며 성장하고 있으며, 기술융합에 초점을 두고 많은 산업들이 성장하고 있는 것으로 파악되었다. 본 연구는 Covid-19의 영향으로 기업투자자 및 예비 창업자들에게 급속도로 변화하는 산업의 흐름을 파악할 수 있게 하고 투자 의사결정에 많은 도움을 줄 것으로 기대된다.

30여 년 전에 연구망으로서 개발이 시작된 인터넷은 현재 사회의 공공 인프라로서의 역할로 기능이 확장되면서 이동성, QoS 지원, 보안성 등을 고려한 점진적 개선이 이루어져 왔다. 그러나, 이러한 점진적 개선 방법의 한계성 때문에 현재의 인터넷 구조가 향후 $20{\sim}30$년 후의 미래사회의 인프라로서도 적합할 것인가에 대한 의구심이 생기기 시작하였다. 이에 따라, 기존 인터넷과의 호환성을 고려하지 않고, 처음부터 현재 및 미래서비스의 요구사항에 기반하여 네트워크를 새로 설계하고자 하는 "미래인터넷" 연구가 시작되었다. 미래인터넷에 대한 연구는 아직 초기단계로서, 거시적 목표를 위해 다양한 네트워크 아키텍처들이 제시되고 있는데, 본 고에서는 미래인터넷의 등장 배경과 지향점, 각국의 연구 현황을 살펴보고, 미래인터넷 아키텍처에 대한 연구자들의 다양한 아이디어를 주요 이슈별로 소개하고자 한다.

The purpose this study was to examine the actual condition and trends in changing the seating style in the house, focusing on the behavioral posture. The data was collected through the self-entry questionnaire designed for this study and the sample of 400 in total, 200 cases from Korea and 200 cases from Japav. The major findings were as the following : the seating style of Korean and japanese female university students were the floor-seating trends in the present conditiov. But they generally preferred the chair seating in the future. In the present seating style, the chair seating style has included bath, study, dinner, sleep, make-up, rest and family communication in that order by Korean Female university students ; the chair seating style has included sleep, study, dinner, make-up, bath, rest and family communication in that order by japanese. In the future seating style, the chair seating style has included study, make-up, dinner, sleep, bath, family communication and rest in that order by Korean ; the chair seating style sleep, study·make-up, dinner, family communication, rest and bath in that order by Japanese.

The 6G mobile communication system will become a backbone infrastructure around 2030 for the future digital world by providing distinctive services such as five-sense holograms, ultra-high reliability/low-latency, ultra-high-precision positioning, ultra-massive connectivity, and gigabit-per-second data rate for aerial and maritime terminals. The recent remarkable advances in machine learning (ML) technology have recognized its efficiency in wireless networking fields such as resource management and cell-configuration optimization. Further innovation in ML is expected to play an important role in solving new problems arising from 6G network management and service delivery. In contrast, an approach to apply ML to a physical-layer (PHY) target tackles the basic problems in radio links, such as overcoming signal distortion and interference. This paper reviews the methodologies of ML-based PHY, relevant industrial trends, and candiate technologies, including future research directions and standardization impacts.

In previous studies we predicted future trends in cancer incidence for each prefecture in order to plan cancer control. Those predictions, however, did not take into account the characteristics of each prefecture. We therefore used the results of age-period-cohort analysis of incidence and mortality data of Osaka, and estimated the incidence and mortality of cancers at all sites and selected sites. The results reflect the characteristics of Osaka, which has and is expected to have large number of patients with liver cancer. We believe our results to be useful for planning and evaluating cancer control activities in Osaka. It would be worthwhile to base the estimation of cancer incidence and mortality in each prefecture on each population-based cancer registry.

Cancer registration provides a firm basis for cancer control efforts and research into changing patterns of incidence, mortality, survival and prevalence is of obvious importance. Most of the countries of Asia have already published relevant data although the level of coverage and accuracy do vary a great deal both between and within countries. The present review concerns the relevant literature for the period 2008-2013, focusing on the types of research conducted and the conclusions that can be drawn with regard to what should be done in the future to translate the information available into effective intervention efforts to reduce the burden of disease. A major emphasis has been on determining variation in incidence and mortality/survival on the basis of ethnicity and socioeconomic as well as geographical background, as well as trends over time, either for cancer in general or specific organ sites. In addition a small number of papers focused on methodological, quality and cancer control issues, very pertinent to the future development of cancer registry based research.
