The conventional SnPb solders were widely used for several decades in the electronic packing system due to the superior mechanical properties such as low melting point, better wettavility and good mechanical fatigue. However, in recent years, owing to adverse effect on the human health and environment, conventional SnPb solders have been replaced by Lead-free solders. In this research, the shear punch(SP) test of Sn-4Ag-(Cu)/Ni pad was performed. Pb-free solder alloys which are the environmentally friendly of the electronic components were performed at $150^{\circ}C$ for 100hr~1000hr to artificial aging processing. In order to evaluate the mechanical properties of solder joints, the SP test was conducted at $30^{\circ}C$ and $50^{\circ}C$. As a result, the maximum shear strength of almost the whole specimens was decreased with the increase in aging time and temperature of SP test. The mechanical properties of Sn-4Ag-0.5Cu solder were most excellent in all Pb-free solder which were produced by the SP test at $30^{\circ}C$.

This thesis aims to identify the design guidelines for environmental plans for the facilities for the aged people with a focus on the users' needs and the concept of aging in place. For this purpose major environmental design factors were researched by analyzing spaces and interviewing the managers and supervisor of W nursing home in Jeju Island that was opened in 1980s. Surveyed factors were divided into five categories, and by applying the design guideline theory of age friendly environment and nursing home facilities to them, five municipal composition factors of Kevin Lynch, universal design, environmental behavior model of John Zeisel principles were found. On the other hand, the environmental changes and development process of W nursing home is a showcase that reveals the importance of narrowing the gap in the opinions of the space users, the experts of architecture and administration which is emphasized in the principles of Inquiry by Design of John Zeisel. This research is expected to be used effectively for the researchers who study the space designs for the age-friendly environment.

최근 전자제품에 납이나 크롬, 수은 등 중금속을 사용하지 않고 환경친화적으로 대체해 가는 업체들이 늘고있다. 선진국에서는 납을 사용하지 않는 무연솔더가 개발되면서 납땜 공정이 거의 사라지고 있으나 무연솔더의 경우 친환경적이지만 가격이 비싸고 납에 비해 접착성과 내구성 등이 떨어져 개량이 필요한 것이 현실이다. 이를 해결하기 위해 TIG 용접을 이용하여 실내등의 도입선과 베이스부에 대한 이종금속 용접기술을 개발하였다. 이를 위하여 기존의 실내등 제작공정을 파악하여 용접 공정으로 대체할 수 있는 방안을 마련하였고 TIG 용접 파라미터의 최적값을 선정하기 위해 시험을 수행하였다. 마지막으로 전구 수명 시험과 내진성 평가를 실시하여 용접된 실내등의 신뢰성을 확인할 수 있었다.

Recently, new aspects of paints such as a beautiful appearance, use of environmentally friendly paints, etc., in addition to the superior performance of paints have been requested for industrial paints including the paints for heavy construction equipment and others. Particularly, the quality of appearance of coating affects the sales of heavy construction equipment. And the necessity for the paints to have a superior weather-proof property without changing the luster or color even after long-time exposure to the open air is emphasized. The change in the surface color and luster of the paint due to the natural environment progresses very slowly, and it takes a long time to verify material properties when developing new paints. In order to improve such methods, weathering tests are performed in many laboratories as a test for accelerating aging of coating, and the lifetime of the products is estimated through evaluation of the weathering (environment-proof) quality of paints. However, not a great deal of research activity has been conducted up to the present time since the interrelationship between the actual results of testing and field data is different for each paint and it takes a long time to study relevant materials. Therefore, introduced in the present study is the estimation of the change in the quality of appearance of coating in the field through the accelerated aging test among the cases of improvement of the quality of appearance of the urethane paint for heavy construction equipment.

선행연구에 따르면 옥외활동은 노인의 신체적, 정신적, 사회적 건강에 긍정적 영향을 미치는 것으로 알려져 있다. 노화가 진행될수록 일상생활이 도보권 내 근린환경과 밀접해지는 가운데, 건강증진을 위한 '활동적 노화'와 '고령친화'는 근린환경에서 실제 이루어지는 옥외활동 수준과 그 인식에 좌우되는 것이다. 이에 본 연구에서는 도시 내 저소득 노인밀집지구의 사례에서 노인의 옥외활동이 근린환경에서 어떻게 이루어지는지 알아보고자 하였다. 또한 옥외활동의 촉진·억제요인이 작용하는 맥락을 시간적·공간적 여건 및 개인적·사회적 여건에 따라 고찰하고자 하였다. 이를 위해 서로 다른 접근방식인 관찰조사와 인지지도 및 심층 인터뷰를 혼합함으로써 질적 GIS 정보를 다각적으로 해석해보았다. 먼저 행태관찰조사를 통해 옥외활동이 이루어지는 주요공간의 활동패턴과 이용자별, 시간대별 특성을 맵핑하여 분석하였다. 또한 거주 노인의 인지지도를 수집하고 주요 외부공간별 근린환경에 대한 인식과 활동목적 등을 인터뷰하여 옥외활동이 이루어지는 상호맥락을 고찰하였다. 연구결과 '시야가 개방'된 쾌적한 공간으로 향하는 '집 바로 앞 골목'의 접근성이나 인지성이 높을 경우 나가고자 하는 욕구가 보다 원활하게 실현되는 것으로 보인다. 노인층에게 '익숙함'이란 것이 매우 중요한 가운데, 공간에 대한 인지성과 접근성을 높임으로써 심리적 경계를 허물어 주는 것이 매우 중요할 것으로 보인다. 또한 사회적 교류와 갈등관계는 노인층의 공간 점유양식에 크게 영향을 미치는 요인으로 확인되었다.
