The masonry structure has been widely used as the dwelling house structure in our country for a long time. The masonry structure is weak in the lateral forces such as strong wind and earthquake. But there is no regulation for it in the domestic aseismic design codes. The purpose of this study is to suggest a simple design method of un-reinforced masonry wall.

컴퓨터 통신망을 통한 자료교환이 증가되고 있는 요즘 정보보호 위협요소 역시 비례하여 증가되고 있다. 거래 상대방과 중요한 상역 거래문서를 전자문서 형태로 주고받는 EDI(Electronic Data Interchange) 는 부당한 행위자에 의한 불법적인 전자문서의 내용 변조 및 누출 그리고 송수신사실에 대한 부인(Repudiation) 등의 여러 위협들에 대항할 수 있는 정보보호 기능을 필수 서비스로 제공해야 한다. 본 고에서는 KT-EDI 시스템의 실제 운영환경을 기반으로 하여 시스템이 제공하는 정보보호 서비스 중에서 기본적인 메세지출처인증(Message Origin Authentication) 서비스와 내용 기밀성(Content Confidentiality) 서비스를 중심으로 UN/EDIFACT 전자문서 레벨에서의 구현에 관하여 다룬다.

기존의 경찰서나 소방서 등에서 사용되고 있는 신고 시스템은 주로 교환기(PBX) 가 포함되어 구축되어 있다. 교환기 자체가 복잡하고 고가 장비이기 때문에 관리 및 운용의 어려움이 있고 시스템 유지, 보수 비용 또한 많이 들게된다. 이렇게 신고 시스템에 사용되는 교환기를 교환기 기능을 하는 보드를 장착한 한 대의 PC로 대체 시킴으로써 구축 및 유지, 보수 비용을 줄이고 단순화 시킬 수 있다는 장점이 있다. 규모가 작은 곳에서는 교환기 기능과 데이터베이스 서버의 역할을 PC 한 대로 통합 구성함으로써 얻어지는 비용 절감은 앞으로 논하고자 하는 UN-PBX 기반 신고 시스템의 최대 장점이라 하겠다. 본 논문에서는 소규모 신고 센터에서 쓰일 수 있는 PC 한 대로 교환기와 데이터베이스 서버를 통합한 UN-PBX 기반 신고 시스템 구현에 관한 내용을 기술한다.

Commercialization and privatization of outer space has been developing to the extent that public space law regime established at the UN seems to be somewhat incompatible with the today' s commercial launching services. Thus, this paper analyzes, at first, the UN space treaties to specify the obstacles for promoting commercial use. The necessity of some covert amendment of UN treaties is suggested through the national space legislation. Then three state practices are examined to propose a new concept of the "launching state" including the Sea Launch project, since the concept of the "launching state" is of the major importance to enact an effective national act to better accommodate UN space treaties to the present necessity.

This paper investigates the design using wind-moment method for semi-rigid un-braced steel frames bending on weak axis. A limiting sway method has been proposed to reduce the frame sway. Allowance for steel section optimization between moment of inertia on minor axis column and major axis beam was used in conjunction with slope-deflection analysis to derive equations for optimum design in the proposed method. A series of un-braced steel frames comprised of two, four, and six bays ranging in height of two and four storey were studied on minor axis framing. The frames were designed for minimum gravity load in conjunction with maximum wind load and vice-versa. The accuracy of the design equation was found to be in good agreement with linear elastic computer analysis up to second order analysis. The study concluded that the adoption of wind-moment method and the proposed limiting sway method for semi-rigid steel frame bending on weak axis should be restricted to low-rise frames not more than four storey.

The cultural art would be the most competitive commercial value in the 21st century. This research is about the stage costumes of the opera 'Ch'un Hyang Jeon'which is designed and made to fit modern times and the purpose is to set the opera 'Ch'un Hyang Jeon'as groundwork for the future opera of Korea. To extend the stage costumes of the Korea opera : First, We have to inform the world about our traditional costumes and design them to express our culture. Second, Not only the costumes but also the technical aspect such as stage music, setting, and lighting and the artistic aspect should be balanced in development. Third, We need a good training system for future designers of the stage costumes.

The advent of the "un-tact 2.0 era," described as a "new normal non-face-to-face social relationship," accelerates the transformation of the living paradigm as a fully digital mediated social relationship. The emergence of these new forms of digital behaviors and mediated relationships significantly influences the industry prospect and consumers' individual lives. Advertising has played a decisive role in moving the formation forces of society, creating a dynamic flow of the capitalist system across races and geographical boundaries. Its role will become more fundamental in the physical contactless environment due to the COVID-19 outbreak. Accordingly, advertising has changed and modified its shape and meaning throughout history to adapt to the dynamic external environment. In this article, we illustrated four primary stages of the evolution in the advertising industry from simple advertising to convergence of advertising. Finally, we also identified the challenges of the present advertising industry and the paradigm transformation of "un-tact 2.0" with various related examples.
