‘지역사회 계속거주(AIP: Aging in Place)’는 자율적이고 독립적인 노년의 삶을 원하는 노인들의 욕구 와 노인시설 운영비용 부담을 줄이고자 하는 정부의 필요성이 부합되면서 인구 고령화에 대처하는 새로운 패러다임으로서 주목받으며 활발히 논의되고 있다. AIP에 관한 국내외의 다양한 연구들은 AIP가 노년기의 삶의 질에 긍정적인 영향을 미치고 있음을 주장하는데, 이는 노인이 자립적으로 생활할 수 있는 사회환경이 제공되었을 때 가능하다. 본 연구는 사람이 살아가는데 가장 기본적인 필수 의료와 임종기 완화의료 및 돌봄 등의 실태를 점검하고 AIP 관련 정책의 현행 법령과 제도를 살펴봄으로써, 국가와 지방정부의 책무는 무엇이며 향후 그 책무를 충실히 이행하기 위한 실효적 방안들은 무엇인지에 관하여 제언한다.

TiN and CrN thin films are among the most used coatings in machine and tool steels. TiN and CrN are deposited by arc ion plating(AIP) method. The AIP method inhibits the reaction by depositing a hard, protective coating on the material surface. In this study, the characteristics of multi-layer(TiN/CrN/TiN(TCT), CrN/TiN/CrN(CTC)) are investigated. For comparison, TiN with the same thickness as the multilayer is formed as a single layer and analyzed. Thin films formed as multilayers are well stacked. The characteristics of micro hardness and corrosion resistance are better than those of single layer TiN. The TiN/CrN peak is confirmed because both TCT and CTC are formed of the same component(TiN, CrN), and the phase is first grown in the (111) direction, which is the growth direction. However, the adhesion and abrasion resistance of the multilayer films are somewhat lower.

The implanting of metal products is performed with numerous surface treatments because of toxicity and adhesion. Recently, the surface modification of metal products has been actively studied by coating the surface of the TiC or TiN film. We prepared a Ti(10%)Ag Target which may be used in dental oral material by, using the AIP(arc ion plating) system TiAgN coating layer that was deposited on Ti g.23. The purpose of this study was to establish the optimal bias voltage conditions of the coated TiAgN layer formed by the AIP process. The TiAgN coatings were prepared with different bias voltage parameters (0V to −500V) to investigate the effect of bias voltage on their mechanical and chemical properties. The SEM(scanning electron microscope), EDS(energy dispersive X-ray spectrometer), XRD(X-ray diffraction), micro-hardness, and potentiodynamic polarization were measured and the surface characteristics of the TiAgN coating layers were evaluated. The TiAgN coating layer had different mechanical characteristics based on the bias voltage, which also showed differences in thickness and composition.
