System reliability prediction in the development stage is increasingly crucial to reliability growth management to satisfy its target reliability, since modern system usually takes a form of complex composition and various complicated functions. In most cases of development stage, however, the information available for system reliability prediction is very limited, making it difficult to predict system reliability more precisely as in the production and operating stages. In this study, a system reliability prediction process is considered when the reliability-related information such as SIL (Safety Integrity Level) and MTTFd (Mean Time to Dangerous Failure) is available in the development stage. It is suggested that when the SIL or MTTFd of a system component is known and the field operational data of similar system is given, the reliability prediction could be performed using the scaling factor for the SIL or MTTFd value of the component based on the similar system's field operational data analysis. Predicting a system reliability is then adjusted with the conversion factor reflecting the temperature condition of the environment in which the system actually operates. Finally, the case of applying the proposed system reliability prediction process to a high performance mooring platform is dealt with.

In 2015, the paradigm of hazardous chemical substance management in Korea shifted from the workplace to the regional level due to the complete revision of the Chemicals Control Act. Although regional chemical accident response plans were established in 2020, there were slight differences in the scope and criteria of each local government. Therefore, this study compared and analyzed chemical accident response plans established in four different regions to provide insights into effective chemical accident response plans. Based on publicly available information, the current status of accident preparedness, chemical accident response systems, and resident evacuation response and education/training were compared and analyzed. The results showed that there were not significant differences in the accident preparedness and response systems between the regions. However, there was a lack of discussion on the preparedness system linked to the characteristics of each workplace in each region. Additionally, there were differences in education and training for residents between regions. In the future, each local government needs to establish a response organization that fits the characteristics of their region and develop strategies for agile and effective accident response through cooperation with relevant agencies.

The paradigm of warfare is undergoing a revolutionary transformation due to the advancements in technology brought forth by the Fourth Industrial Revolution. Specifically, the U.S. military has introduced the concept of mosaic warfare as a means of military innovation, aiming to integrate diverse resources and capabilities, including various weapons, platforms, information systems, and artificial intelligence. This integration enhances the ability to conduct agile operations and respond effectively to dynamic situations. The incorporation of mosaic warfare could facilitate efficient and rapid command and control by integrating AI staff with human commanders. Ukrainian military operations have already employed mosaic warfare in response to Russian aggression. This paper focuses on the mosaic war fare concept, which is being proposed as a model for future warfare, and suggests the strategy for introducing the Korean mosaic warfare concept in light of the changing battlefield paradigm.

This study was conducted to derive theoretical and practical implications in situations where innovation of the business is desperate in the face of the emergence of agile organizations and digital transformation. To do so, we tried to verify the correlation between negative feedback-seeking behavior and innovative behavior and whether the learning goal orientation of these two variables has a moderated mediating effect by coaching leadership. It analyzed the collected questionnaire from 381 members working in domestic companies; SPSS 25.0, AMOS 25.0, and Process Macro 3.0 were used. The analysis result showed that the negative feedback seeking behavior had a positive effect on the learning goal orientation, and the leader's coaching leadership found to have a moderating effect between the negative feedback seeking behavior and the learning goal orientation. Learning goal orientation has been found to have a moderated mediating effect between negative feedback seeking behavior and innovative behavior. This study is significant in the sense that it reveals the process of how members seeking negative feedback in the organization could be led to innovative behavior and shows the necessity of organizational support for coaching leadership for the vitalization of innovative behavior.

In order to cope with the rapidly changing product development environment, individual manufacturing enterprises are forced to collaborate with each other through establishing a virtual organization. In collaboration, designated organizations work together for mutual gain based on product data interoperability. However, product data interoperability is not fully facilitated due to semantic inconsistency among product data models of individual enterprises. In order to overcome the semantic inconsistency problem, this paper proposes a reference ontology, Reference Domain Ontology(RDO), and a methodology for product data interoperability with semantic consistency using RDO. RDO describes semantics of product data model and metamodel for all application domains in a virtual organization. Using RDO, application domains in a virtual organization can easily understand the product data models of others. RDO is agile and temporal such that it is created with the formation of a virtual organization, copes with changes of the organization, and disappears with the vanishment of the organization. RDO is built by a hybrid approach of top-down using a upper ontology and bottom-up based on the merging of ontologies of application domains in a virtual organization. With this methodology, every domain in a virtual organization can achieve product data model interoperability without model transformation.

The purpose of this study was to analyze the effect of using standing step condition on biomechanical variables during jab in boxing. For this purpose, eight orthodox type college boxers(age = 20.38±0.52 yrs, height = 172.38±5.80 cm, body mass = 63.45±8.56 kg, career = 6.00±1.07 yrs) who without injury to the musculoskeletal system participated in the experiment over the last year. In order to verify the effect of biomechanical variables using standing step during jab in boxing, the paired t-test (α = .05) statistical method was used. First, W.S(with-step) showed a greater impact force than N.S(non-step), and muscle activity was analyzed to be low. Second, it was analyzed that the pelvis and foot segments move faster because W.S affects the velocity of the anterior segment of the human body. Third, the rotational movement of the pelvis was faster in W.S. Fourth, W.S was analyzed to have greater ground reaction force in the anterior caused by the right and left foot than N.S. Through this, it was found that the use of the standing step during jab increases the ground reaction force the velocity and rotational movement of the human segment. Therefore, it was confirmed that it allowed a faster and more agile movement, and thus produces a greater impact force with relatively less muscle activity. Therefore, in order to effectively deliver a greater impact force to the opponent during the jab, it was effectively analyzed to accompany the standing step.
