  • Limited and nonlimited emissions of scooters were analysed during several annual research programs of the Swiss Agency of Environment Forests and Landscape(SAEFL, BUWAL). Small scooters, which are very much used in the congested centers of several cities are a remarkable source of air pollution. Therefore every effort to reduce the emissions is an important contribution to improve the air quality in urban centers. In the present work detailed investigations of particle emissions of different 2-stroke scooters with direct injection and with carburetor were performed. The nanoparticulate emissions with different lube oils and fuels were measured by means of SMPS, (CPC) and NanoMet. Also the particle mass emission(PM) was measured with the same method as for Diesel engines. It can be stated, that the oil and fuel quality have a considerable influence on the particle emissions, which are mainly oil condensates. The engine technology influences the (nano)particle emissions by: mixture preparation, mixture tuning, oil consumption, postoxidation, quality, condition and temperature of the catalyst. Since the particulate emission of the 2-S consists mainly of lube oil condensates the minimization of oil consumption stays always an important goal.

  • Purpose: This study aims to explore the distribution of work-life integration against COVID-19 and its Implications by analyzing remote work in Switzerland. Research design, data and methodology: The study performed literature review and descriptive analyses using various data such as perception surveys, statistics, and related documents. Results: The infectious disease was a turning point for many people in Switzerland by changing where and how people want to live. Since the COVID-19 crisis demonstrated that disease could be spread by proximity, negative perception about urban areas expanded, and rural areas are increasingly preferred due to fresh and clean air and a more ecological lifestyle. In addition, increased remote work, a change brought about by COVID-19, has subsequently led to changes in household habits and needs. Distance from work is no longer an important factor when someone chooses where to live. A trend is now emerging where households wanting to improve the quality of life leave the city center and move to the suburbs. Conclusions: Paradoxically, such trend accelerated by the COVID-19 crisis has an unintendedly positive impact on the distribution of work-life integration across society while providing more flexibility in terms of place and time management and lowering the burden on roads and infrastructure.

  • Background : Efforts towards increasing insurance coverage for traditional Korean medicine (TKM) are being continued. However, various difficulties are faced in generating evidence for TKM due to limited financial support and the low quality of research methodology. Objectives : The objectives of this study were to review the Swiss evaluation program for complementary and alternative medicine (CAM) and assess the expansion in public health insurance coverage of complementary medicine as approved by referendum in Switzerland. Methods : The regulations of CAM in the European Union were assessed. Research articles, reports, government publications and websites which deal with the 'Programm Evaluation $Komplement{\ddot{a}}rmedizin$ (PEK)' and the referendum in Switzerland were searched for and analyzed. Results : The PEK was conducted from 1998 to 2005. The PEK evaluated the efficacy, utilization and cost-effectiveness of anthroposophical medicine, homeopathy, neural therapy, phytotherapy and traditional Chinese medicine. However, clear conclusions could not be drawn from the evaluation according to the PEK Report. Later, a referendum was implemented in which 5 therapies would be added to the Switzerland Constitution with the support of the public. The coverage of CAM was approved by Swiss a plebiscite with an approval rate of 67.0%. Conclusions : The reason for the successful referendum is suggested to be public support and the solidarity with CAM experts and politicians. It may be surmised that recognition of the political efforts and scientific aspects required to expand insurance coverage of TKM, and towards obtaining public support, is necessary.

  • The well-established Universal Powder Press UPP, designed by the Swiss press manufacturer Osterwalder AG in Lyss, went through a major improvement process. The result is a high efficient production machine with state-of-the-art technology. It will be shown the technical design, some process engineering as well as the influence of PRP - =Part-Related-Programming, first published in 1994 - on the set-up time. This development has enabled Osterwalder to round off their range of presses, the mechanical-hydraulic KPP as well as the hydraulic CA-NC II and UPP, to an attractive offer ranging from 120 kN up to 10'000 kN.

  • 3D printing of NiTi alloys has been successfully achieved. A novel printing process has been developed and used, which consists in selective deposition of a solvent on a granule bed. The granules are composed of metal powders and thermoplastic binder, which are mixed and sieved by conventional methods. A sound green strength is obtained after solvent evaporation. Sintered parts exhibit good density, proper phase composition and shape memory behaviour.

  • 세계 경제 위기에 따라 심화되는 청년 실업 문제에 대한 해결책으로 도제훈련제도가 제시되었다. 이는 기업이 청년층을 고용하여 직접 인력을 양성하는 제도로서 각국에서 시행하고 있으며, 우리나라에서는 '일학습병행제'로 실시되고 있다. 한국형 도제훈련은 독어권 국가인 독일과 스위스의 도제훈련에 의해 시작되었다. 독어권 국가들의 도제훈련제도는 성공적인 사례로서 공통적으로 기업이 주도하는 수요중심적인 훈련이라는 특징을 갖고 있다. 또한 도제훈련이 교육과정에 통합되어 있어 학업과 연계가 가능했고, 학생 또한 적극적으로 훈련에 참여하고 있다. 이에 본 연구는 성공적으로 운영되고 있는 독일, 스위스, 오스트리아 독어권 국가들의 도제훈련제도를 살펴 공통점과 예비도제훈련과정, 도제훈련과정 운영, 운영주체, 기업 내 트레이너, 비용 편익분석 측면에서의 차이점을 심층적으로 분석하였다. 연구의 결과로 주요요소별 비교사항은 다음과 같다. 첫째, 독일은 도제훈련 이전 예비과정으로 실습을 진행하는 반면, 스위스와 오스트리아는 예비교육과정코스가 운영된다. 둘째, 독일과 스위스는 단일형의 도제훈련을 제공하는 반면, 오스트리아의 경우 모듈형으로 도제훈련을 진행하고 있다. 셋째, 독어권 국가는 사회적 파트너가 적극적으로 참여하는 운영 체계로서 산업이 요구하는 요소를 시스템에 적극적으로 반영하고 있다. 넷째, 독어권 국가는 기업 내 트레이너의 자격을 명시하여 기업 내 현장훈련의 질 관리를 엄격하게 시행하고 있다. 다섯째, 기업의 비용 편익 분석에 있어 독일과 오스트리아는 편익보다 비용이 많이 드는 반면, 스위스는 비용보다 순이익이 발생한다. 이러한 세 국가의 비교 분석을 바탕으로 한국의 일학습병행제에 시사점을 제공하고자 한다.
