As the demand for a healthy life increases and the use of information technology expands, interest in digital healthcare has increased. Among the digital healthcare technologies, digital therapeutics (DTx), which are capable of disease prevention, management, and treatment rather than simple healthcare, are expected to play a key role in future healthcare services. As interest in untact remote treatment that can minimize the risk of viral infection has rapidly increased since the spread of COVID-19, the application of DTx has received much attention because it can partially replace face-to-face treatment for mental illnesses, chronic diseases, and other diseases, reducing concerns about infection. In addition, because of the nature of software, DTx have lower toxicity and fewer side effects than existing treatments and do not require manufacturing, transportation, and storage like general medicines. Hence, they can be supplied in large quantities at low cost and have the advantage of lowering medical costs. However, despite these advantages, it has been pointed out that there are difficulties in investment and universal use because of the complexity of pricing and malpractice compensation. In other words, if it is difficult to prove and measure the improvements in disease management and treatment using DTx and it takes a considerable amount of time and money to do so, it will be difficult to attract investment from stakeholders such as medical providers and pharmaceutical companies. In this paper, we examine the domestic and global application status and development trends of DTx and determine the relevant implications.

This study was conducted for the purpose of systematically identifying research trends in technology transfer and commercialization and setting future research directions in academia. Over a total of 35 years (1987-2021), 146 papers related to technology transfer and commercialization were analyzed for research period, research area, research methods, and research subjects. The research results are as follows. First, the largest number of papers (55) was published during the Park Geun-hye administration. Second, among major academic journals, only the 'Korea Society for Technology Innovation' had a relatively high proportion of research. Third, quantitative research (38%) was the most widely applied research method. Fourth, the most frequent research target was institutions/systems (44%). Additionally, the results of frequency analysis of 729 keywords were presented in a word cloud. This study is significant as the most current study that attempted bibliographic analysis of technology transfer and commercialization research papers over the past 35 years.

As sales of athleisure wear are expected to continue to increase, this study researched and analyzed trends to develop athleisure wear with improved design and functionality. In order to present basic data for designing a research methodology suitable to trends, this study conducted a literature survey related to athleisure wear published in domestic academic journals. The results are as follows. Papers related to athleisure wear have been consistently published since 2016, when athleisure wear began to emerge in Korea. The research methodology itself has not yet been reflected in a variety of ways, and it has only been published at a general level, so there is a need to expand the research methodology. In particular, the lack of material-related research in athleisure wear, where functional materials play the most important role, can also be cited as a problem. Research in the field of clothing composition for movement suitability and functional design is also limited to leggings and should be expanded to various athleisure wear items. However, due to the characteristic of athleisure wear, research papers are published not only in academic journals in the field of clothing, but also in academic journals in the fields of convergence, science, and sports. It is expected that active research on athleisure wear will continue in the future through a multifaceted and convergent approach.

The purpose of this study was to explore research trends in sleep from infancy through to adolescence. To achieve this, an examination was conducted of sleep research published in Korea based on the publication year, developmental stages of the study participants, research designs, measurement tools, and research topics. A total of 362 academic journal articles and theses/dissertations published in Korea up until 2023 were selected. In terms of publication year, the first study was conducted in 1967 and the field became more active from 2010 onwards. The age group studied the most was adolescents, with cross-sectional research being the most common study design. Regarding sleep measurement tools, most scales measuring sleep in infants, preschoolers, children, and adolescents were developed abroad, then adapted or validated in Korea, or were modifications of adult scales tailored for specific studies. Lastly, in terms of research topics, the most common focus was the relationship between sleep and developmental characteristics, particularly its effects on emotional development. Based on these results, future research could focus on developing sleep-related intervention programs and measurement tools.

Among many material processing related issues for successful scaling down of devices for the next 10 years or so, the advanced gate stack and interconnect technology are two most critical research areas, which need technical innovation. The introduction of new metallic films and appropriate processing technologies are required more than ever. Especially, as the device downscaling continues well into sub 50 nm regime, the paradigm for metal nano film deposition technique research has been shifted to high conformality, low growth temperature, high quality with uniformity at large area wafers. Regarding these, ALD has sparked a lot of interests for a number of reasons. The process is intrinsically atomic in nature, resulting in the controlled deposition of films in sub-monolayer units with excellent conformality. In this paper, the overview on the current issues and the future trends in device processing technologies related to metal nano films as well as the R&D trends in these applications will be discussed. The focus will be on the applications for metal gate, capacitor electrode for DRAM, and diffusion barriers/seed layers for Cu interconnect technology.

A linear reservoir rainfall-runoff system was developed as a rainfall-runoff event simulation model. It was achieved from large modification of runoff function method. There are six parameters in the model. Hydrologic losses consist of some quantity of initial loss and some ratio of rainfall intensity followed by initial loss. The model has analytical routing equations. Hooke and Jaeves algorithm was used for model calibration. Parameters were estimated for flood events from '84 to '89 at Seomyeon and Munmak stream gauges, and the trends of major parameters were analyzed. Using the trends, verifications were performed for the flood event in September 1990. Because antecedent rainfalls affect initial loss, future researches are required on such effects. The estimation method of major parameters should also be studied for real-time forecasting.

전문 서비스로봇인 국방 무인 로봇은 무기체계 개발 시, 소요군의 운용개념 미확정, 국내 로봇 기술수준(TRL) 및 기술성숙도 미흡 등으로 무인체계의 소요기획 및 전력화 소요 반영이 되지 않고 장기적인 획득 대안으로 생각하고 있으나, 미국의 미래 전투체계(Future Combat System)에서 보듯이 네트워크 중심전(NCW)으로의 전장 환경변화 등 무인전투체계의 통신 및 소프트웨어(복합체계 공통운용환경(SOSCOE: System of Systems Common Operating Environment))의 중요성은 더욱 커지고 있다. 국가적으로는 국방 무인 로봇을 시장확산분야로 인식하고 있으며, 그동안 해외 도입 위주의 국방 무인 로봇 시장에 대한 중요성이 부각되고 있어, 우리나라 창조경제 발전의 견인차 역할로 무인체계 시장의 선점 및 새로운 고용시장을 창출할 수 있는 기반으로 투자를 확대하고 있다. 따라서, 본 논고를 통하여 무인체계에 대한 체계개발 활성화 방안에 기여하기 위한 선제적인 방법으로 연구개발 방향을 설정하고, 기술개발 방향 및 획득 우선순위 등 개발전략을 수립하고 그 대안을 제시하고자 한다.
