A transition-based Objet-oriented programming system(TOPS) is a transition-based object-oriented system suitable for development of various concurrent systems.A TOPS consists of a collection of interacting structural active objects(SAOs),and their behaviors are determined by the transition statements provided in their class definitions.Furthermore,SAOs can be structurally and hierarchcally composed from their component SAOs like hardware commponents. These features allow SAOs to model components for circuit simulation more naturally than passive objects used in ordinary object-oriented programming. Also,we can easily add new kinds of components by using the inheritance mechanism.Executions of transition statements may be eventand/or time-driven, and hence digital,and mixed-mode simulation is possible.Prototype simulation programs with graphical user interfaces have been developed as TOPS progrms for digital,analog,and mixed-mode circuit simulation.

The purpose of this study was to identify the relationships between nursing competency and emotional intelligence and nurse role transition of nursing students. Study participants were 134 nursing students of university in Chungnam province. Data were collected with the use of self-administered questionnaires from November 1 to December 10, 2018. Collected data were analyzed using the IBM SPSS 20.0 program. Nurse role transition of nursing students showed positive correlation with nursing competency(r=.79, p<.001) and emotional intelligence(r=.59, p<.001). Factors influencing nurse role transition of nursing students were nursing competency(${\beta}=.66$, p<001) and emotional intelligence(${\beta}=.22$, p=.001), which accounted 67.8%. These results indicate that various educational programs to increase nursing competency and emotional intelligence of nursing students are needed to increase nurse role transition. Studies on the effectiveness of provided programs are also needed to provide more effective programs.

In digital mobile communication system, the transmission errors affect the quality of output speech seriously. There are many error concealment techniques using a posteriori probability which provides information about any transmitted parameter. They need knowledge about channel transition probability as well as the 1st order Markov transition probability of codec parameters for estimation of transmitted parameters. However, in applications of mobile communication systems, the channel transition probability varies depending on nonstationary channel characteristics. The mismatch of designed channel transition probability of the estimator to actual channel transition probability degrades the performance of the estimator. In this paper, we proposed a new parameter estimator which adapts to the channel characteristics using short time average of maximum a posteriori probabilities(MAPs). The proposed scheme, when applied to the LSP parameter estimation, performed better than the conventional estimator which do not adapt to the channel characteristics.

Todays, there is fast transition about the new manufacturing IT methodologies from the conceptual phase into the practical application phase for the strengthening of enterprise competitiveness in manufacturing industry. One of those new methodologies is PLM (Product Life-cycle Management). PLM methodology consists of 3D CAD for the product design, PDM (Product Data Management) for the data management based on the collaboration platform and lastly DM (Digital Manufacturing). DM has evoluted from the stand-alone computer simulation of early 1980s, and now it covers the overall production development and production. Unfortunately, there exist serious critical problems about the actual application of DM for the real work. This is owing to the transition of the point of view from stand-alone type application (such as flow simulation or robot simulation) to that of business process about product development and production management. In this paper, we propose an application framework for the successful project with the digital manufacturing methodology with the concept of Information Strategy Planning, which enables the systematic diagnosis and the quantitative evaluation. Also, we introduce the actual practice of the proposing framework with the ISP project for 'Analysis & Simulation Technique of manufacturing process project' that is being conducted by Chungnam Techno Park.

This study applies Policy Streams and Expert Group Standing Change Framework (PSECF) proposed by SangJung Park and Chan KOH to analyze the Roh's Participatory government's decision making process on the wartime Operational Control (OPCON) transition. PSECF case study's results are as follows: Strong commitments of the former president Roh Moohyun and the progressive National Security Committee (NSC) were primary drivers in the policy developing process. But military expert groups such as the Ministry of National Defense (MND) and the Joint Chiefs of Staffs (JCS) were thoroughly excluded due to their passive role against the wartime OPCON transition. After the policy resolution, the standing of expert groups changed: the standing of advocate effects, the former progressive NSC who led the wartime OPCON transition in the Roh's Participatory government, went down but the conservatives such as ROK MND and JCS improve their standing because the conservative government kicks off 8 months later from the policy decision. In conclusion, the proposed PSECF through the Roh's Participatory government's case-study is worthy as an explanatory framework for high level national policies.

This study analyzes the military and political factors that influenced the Participatory Government's resolution in Wartime Operational Control (OPCON) Transition. The research on key factors in OPCON transition firstly implemented literature research and then increased feasibility through additional use of AHP. The analysis results showed that there was a negative effect for Korean Peninsular Defense in the 'ROK-US Alliance Asymmetry' area, a positive effect to increase ROK-led Capability of Theater Operation in the 'ROK and U.S. Alliance Interdependence' area and a positive effect for Invocation of ROK Self-Defense Power in the 'Interests of Participatory Government's Liberal Regime' area respectively. After applying AHP, "ROK exercise of Self-defense" in the 'Interests of Participatory Government's Liberal Regime' area received the highest assessment, while the "Increasement of North Korea's Threat" in the 'ROK-US Alliance Asymmetry' area received the lowest assessment. This study is meaningful in that it analyzed the key military and political factors in the Participatory Government's resolution of Wartime OPCON Transition using AHP.

The main purpose of the study is to determine the main elements of the use of digital technologies for learning a foreign language in educational institutions. The era of digital technologies is a transition from the traditional format of working with information to a digital format. This is the era of the total domination of digital technologies. Digital technologies have gained an unprecedented rapid and general distribution. In recent years, all spheres of human life have already undergone the intervention of digital technologies. Therefore, it is precisely the educational industry that faces a difficult task - to move to a new level of education, where digital technologies will be actively used, allowing you to conveniently and quickly work in the information field for more effective learning and development. The study has limitations and they relate to the fact that the practical activities of the process of using digital technologies in the system of preparing the study of a foreign language were not taken into account.

The pace of sustainability transition within the maritime industry has been accelerating. This shift primarily necessitates changes in the industry's heavy reliance on fossil fuel-driven ecosystems. Additionally, numerous sustainability laws and regulations, such as the EU's CBAM and IMO's EEXI, have been implemented. This transition is poised to amplify the competitive edge of firms equipped with greater resources, as it introduces substantial operational burdens due to expensive eco-friendly fuel adoption and regulatory compliance. To diverge from the traditional competitive landscape, this paper aims to explore innovative maritime finance models enabling domestic firms to gain competitive advantages on a global scale. Employing analogical reasoning and modeling as a research method, this paper demonstrates that maritime firms can leverage the sustainability transition by aligning sustainable maritime operations with ETS (Emission Trading Schemes). Expanding on this novel approach, the paper delves into potential connections between CCM (Compliance Carbon Market), VCM (Voluntary Carbon Market), and digital asset exchanges. This newly proposed digital/net-zero maritime ecosystem holds the potential to significantly impact the shipping, shipbuilding, and ship finance industries, positioning Busan as a sustainable maritime finance hub. This study holds significance as pioneering research that may stimulate subsequent case-based studies and offer strategic guidance to market participants and policymakers as the maritime industry moves towards a net-zero transition

This paper describes the design of a variable rate QPSK demodulator for digital satellite TV system. This true variable-rate demodulator employs a unique architecture to realize an all digital synchronization and detection algorithm. Data-flow based design approach enabled a seamless transition from high level design optimization to physical layout. The demodulator has been integrated with Viterbi decoder, de-interleaver, and Ree-Solomon decoder to make a single chip Digital Video Broadcast (DVB) receiver. The receiver IC has been fabricated with a 0.5mm CMOS TLM process and proved fully functional in a real-world set-up.
