As an example of modern mathematical physics, we introduce quantum logic and its propositional system in foundation of quantum theory. We then show that how the conventional quantum mechanical formalism in Hilbert space can be obtained naturally from the obstract prepositional system. We also discuss briefly the roles of mathematics in modernphysics.

As the areas of computer application are expanded, real-time application environments that must process as many transactions as possible within their deadlines, such as a stock transaction systems, ATM switching systems etc, have been increased recently. The reason why the conventional database systems can't process soft real-time applications is the lack of prediction and poor performance on processing transaction's deadline. If transactions want to access data stored at the secondary storage, they can not satisfy requirements of real-time applications because of the disk delay time. This paper designs a main-memory database prototype systems to be suitable to real-time applications and then this system can produce rapid results without disk i/o as all of the information are loaded in main memory database. In thesis proposed the improved techniques with respect to logging, checkpointing, and recovering in our environment. In order to improve the performance of the system, a) the frequency of log analysis and redo processing is reduced by the proposed redo technique at system failure, b) database consistency is maintained by improved fuzzy checkpointing. The performance model is proposed which consists of two parts. The first part evaluates log processing time for recovery and compares with other research activities. The second part examines checkpointing behavior.

고밀도 수송 시스템이 당면한 국내 · 외의 상황을 보면, 안전관리 현안에 대한 대책 등이 지속적으로 관심을 사고 있다.본 논문에서는 출입문 장치를 단품(LRU, Line replace unit)이 아닌, 주요 부품의 위험경재 모형인 직렬연결의 결합으로 모델링하고, 이에 대한 신뢰도 지표산출과, 단품의 개조로 신뢰도가 향상될 때 출입문 장치의 신뢰도 지표 변화에 관해 논하고자 하였다. In situations other than domestic · high density transportation system at hand, buying measures such as interest continuously for safety issues. In this paper, not a single item (LRU, Line replace unit) for door devices, the risk hardwood major parts model, modeling a combination of serial connection, and thus the reliability indicators for output and, when converted to improve the reliability of the a la carte was to talk about the changes in the confidence indicators door unit.

Recently, It was not sufficiently prepared a realistic ways for the effect measurement of digital media advertising due to the lack of concepts or platforms for new media advertising and advertising standardization. This is the biggest problem. The advertising effective measurement system technique uses the camera which attaches in TV and It measures and manages watching behavior recognition information about broadcasting/advertisement contents. Also it analyzes the information which are collected for advertizer or advertisement vicarious execution company in effective index. and it provides the program rating and advertisement effective measurement and analytical results which are accurate and various. In this paper, we proposed the structure, function and service model of the effect measurement system of smart media for building the smart broadcast advertising effectiveness measurement system. In particular, We tried to present the advertising effect measurement system for effect measurement data collection and analysis based on watching behavior in the smart media environment of being activated from the convergence field of broadcasting and communication.

Following the global air-traffic market growth outlook, urgency of technical development is needed in responding to changes in the international air-traffic management paradigm and to prepare technology securing and spreading strategies, which are consistent with systematic aviation weather service policies and evolution direction. Although air traffic has decreased significantly due to COVID-19, normalcy is expected from 2024, as announced by IATA. According to the future air transportation market outlook and development trends of related technologies, Korea has established and implementing the next-generation air transportation system construction plan(NARAE) to secure international competitiveness and leadership in the future. Therefore, this paper describes the technical, economic background and requirements of numerical model-based aviation weather R&D projects for successful implementation of domestic NARAE plans and providing aviation safety and air traffic service efficiency. Furthermore, we proposed numerical-model-based technology development content, strategies and detailed load-map.
