There has been skeptical aspects for the robot to be effective in combat fields even though consensus of operational needs and some technological advancements. One of fundamental problems is difficulties in the autonomous technology applicable. This technology is not sufficient to be applied for heavy combat operation, therefore, developer first make open architecture, then, application is implemented on the condition that new functions or technologies will be developed later. It is also required to partition all the functions with common segments which are general to all platforms in order to operate together in the fields and to reduce the load of development to each platform respectively. In addition, common middleware based on the reference architecture is also developed to accommodate new technology evolution. This paper introduces the architecture and middleware applied in XAV(eXperimental Autonomous Vehicle) developed in ADD. In addition, the performance of autonomous navigation and system design characteristics are introduced briefly.

The office-based, un-sedated vocal fold injection laryngoplasty has re-emerged in the past decade as an appealing alternative to microsuspension laryngoscopic procedure which is conducted under general anesthesia. The trend toward vocal fold injection laryngoplasty in an in-office setting was possible due to technological evolution for visualization and new injection materials. However, invisibility of the injection needle has been the main shortcomings of cricothyroid approach. The purpose of this review is to provide an up-to-date review of office-based, trans-cricothyroid membrane approach injection laryngoplasty technique under local anesthesia and efforts made to increase the preciseness of amount and location of the injected materials in the management of glottic insufficiency. A review of variable efforts undertaken to maximize the result of cricothyroid approach by technically increasing accuracy of the location of needle tip was done. With the proper patient selection and utilization of the new technologies, office-based and un-sedated vocal fold injection laryngoplasty via cricothyroid approach can be redeem as a main-stay in the management of glottic insufficiency, such as vocal fold paralysis, vocal fold paresis, vocal fold atrophy and vocal fold scar.

Corporate business clusters create a borderless business network through value chains and value creation activities. Clusters in the IT sector are crossing regional boundaries because of their rapid technological development and short product life cycle. To investigate this phenomenon, we examined the value activities of IT companies. As a result, the global expansion of the case companies was limited, but they had business clusters that exceeded the regional boundaries. However, because the order of business clusters is not advanced, value activities are focused on productivity rather than innovation. Given the rapidly evolving nature of IT, it is necessary to evolve into a business cluster that can create new value. Companies must design and implement value-creating processes to develop new technologies or enter new markets, which can lead to cluster growth. Companies must design and implement value-creating processes to develop new technologies or enter new markets, which can lead to cluster growth.

The naval combat system is gradually evolving, actively accepting technological advances. The domain components of the naval combat system must also be adapted to the gradual evolution of the naval battle system. In other words, domain components should be easy to change. However, existing domain components do not fully consider changeability. In particular, when receiving more messages than planned from the middleware, it does not consider a way to process them in a timely manner. We propose a domain component reference architecture for timely processing of increased messages. The proposed architecture separates domain components so that business logic can operate independently, and sets up multiple business logic to operate simultaneously to handle increased messages. The track management domain component is designed using the proposed reference architecture to confirm the applicability.

This study aims to 1) summarize the definitions the definitions of afrofuturism through a theoretical review 2) through exploratory empirical research, and 3) recover the concept of reversal in relation to the turning point of future technological development. To this end, first, the theoretical background and conceptual discussion of Afrofuturism were examined, and works in the field of SF literature, music, and art were analyzed. Octavia Butler's science fiction confirms the idea that black people must liberate themselves from othered oppression by bringing the past of slavery to the forefront of the world. Janelle Monae's music presents a liberated utopia where technology allows minorities to connect with the outside world. In addition, Jean-Michel Basquiat's artwork reimagines a black identity that has been excluded and seeks to expand communal discussions. In light of their work, this paper proposes that the values inherent in African humanism can provide clues to the co-evolution that is generated by relating to the Other in the face of exponentially advancing technology.

Large language models (LLMs) have revolutionized the global landscape of technology beyond the field of natural language processing. Owing to their extensive pre-training using vast datasets, contemporary LLMs can handle tasks ranging from general functionalities to domain-specific areas, such as radiology, without the need for additional fine-tuning. Importantly, LLMs are on a trajectory of rapid evolution, addressing challenges such as hallucination, bias in training data, high training costs, performance drift, and privacy issues, along with the inclusion of multimodal inputs. The concept of small, on-premise open source LLMs has garnered growing interest, as fine-tuning to medical domain knowledge, addressing efficiency and privacy issues, and managing performance drift can be effectively and simultaneously achieved. This review provides conceptual knowledge, actionable guidance, and an overview of the current technological landscape and future directions in LLMs for radiologists.

Products elicit the consumer's purchasing behavior by satisfying their needs and are cognized as the combination of various needs attributes. Also R&D is referred as a series of technical development activities to meet the consumer's needs attributes. In particular, in the market-oriented R&D era, it could obtain the legitimacy by developing the R&D based on the needs attributes. In this study, we aimed to investigate the priority setting in R&D field, considering consumer's needs attributes. To be concrete, we tried to present the evolutional direction of desirable phased R&D according to 'the importance degree for consumers on the attributes (functions) of the certain products' and 'the urgency degree of technical quality to fulfill its needs'. To achieve this, we targeted SMART TV, the convergence product, which contains the uncertainty in terms of marketability and technological aspect, and analyzed the priority of the R&D in SMART TV field. Based on the result of the analysis, 4-steps product concept (ultra high definition TV, interactive TV, 3D/immersive TV, personalized TV) is derived by analyzing the evolutional direction of R&D in SMART TV field. This finding implies that the success possibilities of product could be enhanced during the process of the evolution of products that have multiple needs attributes, by pursuing the R&D which fulfills the needs attribute first required in the market. In addition, it provides a useful framework to design the R&D roadmap in an aspect of R&D strategy.

Despite many previous studies on catch-up, understanding on the effect of product architecture developed by latecomers on the catch-up performance remains limited. On the other hands, in contrast to the semiconductor, ship building, and automotive industry, even if Korean industry and government have invested the development of numerical controllers for machine tools in the past four decades, the industry and government have failed to achieve catch-up. Therefore, we newly examine the effect of product architecture on the catch-up performance of the Korea by implementing comparative research with periods on the evolution of product architecture of Fanuc's numerical controllers, which have achieved the largest market share in the world. We found that Fanuc developed open modular architecture based numerical controllers and provided product with customization of user requirements as well as cost effectiveness. Consequently, Fanuc has sustained market leader position since the mid-1980s. However, despite all the efforts of the industry and government, we found that the Korea failed to develop open modular architecture based numerical controllers and could not achieve significant catch-up performance. Our findings provide important theoretical backgrounds for examining the catch-up performance as well as investigating the reason why latecomers failed to achieve market catch-up even if they accomplished technological catch-up.
