  • 종래 국내 교환기 시스템에서 번호 번역 처리 등의 공통 절차들은 전통적으로 중앙 프로세서에서 수행한다는 개념에서 벗어나지 못했다. 이들 호처리 수행의 공통 절차들은 최번시 중앙프로세서로 상당한 부하를 가중시키고, 곧 시스템의 전체 호처리 수행 능력이 중앙 프로세서의 성능에 종속되는 문제점으로 지적되어 왔다. 본 고는 일반 국번 번역 기능을 전담하는 신규 라이브러리를 ASS 서브시스템에 구성하므로서 시그널 송수신 절차를 간소화하고, 국번이나 착신번 번역 기능이 중앙 집중형 프로세서에서 제어되므로서 갖는 시스템 성능의 제약을 해결하기 위한 방안을 제시하고자 한다.

  • 블록체인 기술의 발전과 중앙집중형 금융서비스의 취약성과 불신에 대한 우려가 커지면서 탈중앙화 금융(DeFi)과 탈중앙화 거래소(DEX)가 유망한 대안으로 떠올랐다. 본 논문에서는 특히 Uniswap에 초점을 맞춰 DeFi 내의 과제와 문제를 살펴본다. 우리는 DeFi 및 DEX의 현재 상태에 대한 배경 지식을 제공하여 MEV(Maximal Extractable Value) 공격에 대한 취약성을 강조한다. 우리의 접근 방식에는 MEV 공격 패턴을 식별하고 분석하기 위한 Uniswap에 구조 분석이 포함된다. 이 연구는 DEX 보안을 강화하고 MEV 위험을 완화하기 위한 귀중한 지침을 제공하여 DeFi 생태계의 이해관계자에게 필수적인 리소스 역할을 한다.

  • The corrosion loss of the shell plates and the bulkead plates of the oil tankers, nationalities of which belong to korea are determined and analyzed. The thickness of the plates are determined by use of the ultrasonic thickness meters at the check points set along the fore and aft line and the perpendicular to it. Difference between the original thickness and the determined one are given as the corrosion loss at the present age. 1. On the shell plates (1) The total mean of the corrosion loss shows the greatest value on the load water line in every age classes of the vessels. (2) The total mean of the corrosion loss on the fore and aft line shows little difference, even though it is slightly greater at the fore part, in every age classes of the vessels. (3) The corrosion loss along the perpendicular grows greater in the order of upper bilge line, light water line, freeboard line and load water line at 16 ages of the vessels, and the loss changes in the order of light water line, upper bilge line, freeboard line and load water line at 20 ages of the vessels. (4) The total mean of the corrosion loss along the light water line and upper and lower water line shows the greatest value on the fore part. That along the freeboard line and the load water line shows the greatest value on the midship part and on the after part, respectively. 2. On the bulkhead plates (1) The total mean of the corrosion loss shows the greatest value on the top part at the every age classes of the vessels. (2)The corrosion loss along the perpendicular grows greater in the order of the lower, center and upper part at every age classes of the vessels. (3) The total mean of the corrosion loss at the top part grows greater in the order of the transverse bulkhead of the side oil tank, that of center oil tank, longitudinal bulkhead of center oil tank, and transverse bulkhead of side water tank at the 20 ages of the vessels.

  • The purpose of this study is to analyze how Andong Joongang Cinema (hereinafter referred to as "The Cinema"), the only art cinema in Gyeongsangbuk-do Province, is perceived by local people as a local cultural resource. For this, an analysis framework was set for analyzing local people's perception of The Cinema as a local cultural resource, by analyzing the functions of local cultural resources and the function of The Cinema and examining the correlation between the two sectors, on the basis of precedent studies on local cultural resources and related papers on art theaters and The Cinema. Based on the proposed analysis framework, the local people's perceptions of The Cinema as a local cultural resource were summarized into four divisions: the perception of the enjoyment of culture & art, the perception of historicity, the perception of a tourist attraction, and the perception of community formation. As a result, it is judged that The Cinema has the identity, the traditionality and the community spirit as the three functions of which a local cultural resource has, and thus, it is proved that The Cinema functions as a local cultural resource. Therefore, local cultural resources have been performing their functions encompassing its scope with the region's history and surrounding environment, not standing alone. The Cinema also has been functioning as a space for the enjoyment of culture and art, a tourist attraction, and a cultural space for communicating with the public, keeping its historicity of the region. It is expected that there will be specific follow-up studies so that The Cinema can consistently play its role as a local cultural resource.
