As facilities in apartment unit by age, residents feel uncomfortable in their lives, but maintenance and management are not carried out properly. For the systematic maintenance of facilities, the derivation of facilities that require maintenance shall be preceded. This study aims to derive items that require intensive management among exclusive facilities. The purpose of this study is to analyze the history of repairing facilities through complaints about the exclusive use of public rental housing to identify the cause and to derive items that require intensive management of the exclusive use of apartment houses.

최근 해양구조물의 수직 칼럼부 용접 공법은 FCAW에 의한 다층 용접으로, 작업 시수와 작업자의 피로 가중 등, 생산 효율면에서 단점이 많았다. 이를 개선하기 위해 최초로 EGW에 의한 단층 용접을 적용하고자 EGW 적용시의 용접강도 및 피로 안전성을 평가하기 위한, 피로 시험을 수행하였다. (중략)

This study investigates the effects of individual and group level factors on the use of GSS (Group Support System) and task performance from GSS use. GSS facilitates the group work, so that GSS adoption is not necessarily influenced only by individual perceptions on information systems. Adaptive Structuration Theory (AST) in our study to explain the adoption and success from GSS use. AST contends that the success of IS is not necessarily the technical fit between tasks and technology, instead the political outcome among user socializations. We have the following two research inquires: Are the IS use and performance maximized when information technologies are provided properly?; and, Does TTF always influence positively on IS use (or performance)? To research these issues, we investigate the influence of TTF (Task-Technology Fit) on use and performance of GSS, which is introduced to foster collaboration among organizational members. Drawing insights from the AST, we examine if COA (Consensus on Appropriation) among group members and FOA (Faithfulness of Appropriation) between those who use technology and who design it show any moderating effect. A questionnaire survey was conducted on firms using the GSS for one month from June 2 to June 27 2005 and a sample of 303 responses was used for a statistical analysis. The result demonstrates that TTF exerts a positive influence on use and performance of GSS. We find that the stronger the COA, the greater the effect of W on use of GSS and performance. FOA likewise has a positive effect on both use of GSS and performance. The TTF model has been widely applied to studies on individual performance of information system, whereas the AST theory specifically explains members' adaptation process to information system. By integrating the AST theory with the TTF model, the study contributes to heightening our understanding on if and how individual performance varies with the use of GSS.

생체인식 기술의 발달에 의해 생체 인증 수단 또한 늘어남에 따라 사용자의 얼굴을 이용한 인증방법이 점차 실용화 되어가고 있다. 그러나 주변 환경에 제약받을 경우 완벽한 인식률을 보여주지 못하는 경우가 발생한다. 본 논문에서는 기존의 얼굴인식 방법의 오탐지 부분에 대한 개선방법을 제안 하고자 하였다. 디지털 영사식 방법을 통한 무아레 현상을 얼굴인증에 접목시켜 보다 정확한 얼굴 인증을 진행할 수 있도록 개선된 인증 방법을 제시한다.

본 논문에서는 구글 탱고 플랫폼을 이용하여 3차원 스캐닝 기법을 이용하여 생체인증에 적용방안을 제시한다. 모바일 기기에서 탱고 플랫폼을 이용하여 얻은 생체정보를 저장시킨다. 생체정보를 통해 얻은 데이터를 이용하여 특정한 템플릿을 추출한다. 추출된 특징점은 인증서버로 옮겨져 기존에 등록해 놓은 특징점과 비교하고 FIDO 방식을 이용하여 인증하는 방법을 제안한다.
