  • It is challenging work to predict weather and climate conditions of the future in advance. Since ENIAC was developed, weather and climate research areas have been taking advantage of the improvements in computer hardware. High performance computers allows researchers to build high quality models that allow them to make good predictions of what might happen in the future. Statistics on the high performance computers are one of the major interest to not only manufacturers but also the users such as weather and climate researchers. For this reason, the Top500 Supercomputer Sites Report has been being released twice a year since 1993 to provide a reliable basis for tracking and detecting trends in high performance computing. Using the Top500 Report, a short review on the supercomputer trends in weather and climate research areas is provided in this article.

  • In the digital era, broadcasting plays a very large role as a means of communication, as it no longer merely provides information or entertainment media. Particularly in the case of the visually and hearing-impaired, broadcasting is the primary means of acquiring information, so its role as a public service needs to be expanded. The development of digital technology enables the quantitative expansion of traditional methods of disability broadcasting, i.e., closed caption, sign language, and descriptive video service, with an acceptable level of quality. In this study, we review the current trends of, and concerns related to, broadcasting services for disabled people, as well as technological trends, and proposals for increasing visibility and accessibility to broadcasting for hearing-impaired people.

  • Development of technology in the $20^{th}$ century has made great contributions to women's lives. With the development of digital convergence, home network, and DMBs (Distance Method Bracings), the ubiquitous technology information era is expected to create a new progressive era for women. The purpose of this study is to investigate the lifestyle that Korean women would like to pursue, especially in regards to the sense of value within the personal and social life of each individual. As a method to suggest how the socio-cultural trends of women's lifestyle will change in the ubiquitous era, qualitative interviews have been conducted over 6 groups with 77 persons between the digital ages of 20s and 30s, living in Seoul. The majority had positive opinions regarding the economic, cultural, emotional, and physical prospects of the ubiquitous information environment. Results show high expectations evolved around freedom from household chores, the equality between the sexes (at home and in society), enhancing the working environment at home, an expansion of human relationships leading to creative knowledge, being able to maintain a single life without economic constraints, and the enjoyment that the internet provides. for suggestions to improve the quality of women's lifestyle through ubiquitous technology, issues such as individual based customization, time management, creating emotional hyperspaces, multi-media communication systems, and women as leaders were studied.

  • Purpose The purpose of this study is to analyze the trend of patent technology in textile materials using text mining methodology based on Dynamic Embedded Topic Model and Structural Topic Model. It is expected that this study will have positive impact on revitalizing and developing textile materials industry as finding out technology trends. Design/methodology/approach The data used in this study is 866 domestic patent text data in textile material from 1974 to 2020. In order to analyze technology trends from various aspect, Dynamic Embedded Topic Model and Structural Topic Model mechanism were used. The word embedding technique used in DETM is the GloVe technique. For Stable learning of topic modeling, amortized variational inference was performed based on the Recurrent Neural Network. Findings As a result of this analysis, it was found that 'manufacture' topics had the largest share among the six topics. Keyword trend analysis found the fact that natural and nanotechnology have recently been attracting attention. The metadata analysis results showed that manufacture technologies could have a high probability of patent registration in entire time series, but the analysis results in recent years showed that the trend of elasticity and safety technology is increasing.

  • 국내에서는 정보통신산업의 확장과 미래 경쟁력 확보를 위하여 기술개발 및 기업육성을 위한 활동들을 추진하고 있으나 차별화된 전략이 부족한 실정이다. 이에 본 연구에서는 표준특허를 중심으로 한 분석을 통해 관련 기술동향과 융복합 정도를 파악함으로써 정보통신산업 분야의 효율적인 미래기술 발전전략을 수립하는데 방향을 제시하고자 하였다. 기존의 연구가 일반적인 기술적 흐름만을 살펴보았다면 본 연구에서는 파급효과와 활용성이 큰 표준특허를 중심으로 연구함으로써 급변하는 기술변화 속에서 미래 산업 예측을 명확히 할 수 있다. 본 연구에서는 정보통신산업 관련 표준특허 1,983개를 분석하여, 전 세계 주요 특허출원인과 세부기술별 특허 동향을 파악하였다. 또한 키워드분석을 통해 기술 동향을 조사하였으며 네트워크분석을 통해 정보통신기술의 융복합성 정도를 조사하여 대상 기술 분야인 정보통신산업에 대한 연구방향을 확인할 수 있었다. 전자부품 및 무선통신 분야는 표준특허가 상대적으로 적은 반면 타 산업 기술과의 융합성이 높게 나타났고 컴퓨터 정보 프로세스와 통신·방송기술은 서로 관계성이 높아 표준특허에서 융복합 기술로 활용할 만한 것으로 분석되었으며 광학 및 영상·음향기기 분야는 표준화 활동정도가 높은 것으로 파악되었다.

  • Ship Information Systems (SISs) have been one of the main research focuses in ship design and become a multidisciplinary area. With these growing research trends, it is important to consolidate the latest knowledge and information to keep up with the research needs. In this paper, the SIS and its different forms are introduced and discussed. The beginning of this paper discusses the history and evolution of SIS. The next part of this paper focuses on different fields and research areas such as networking technology, information fusion, information decision, message display, ship control in real-time SISs. A Semi-Physical Simulation Platform (SPSIM) designed for SIS research and its running effect through a new Fuzzy-PID fusion algorithm are introduced in this paper then. A brief literature survey and possible future direction concerning each topic is included.
