ABSTRACT

Previously, heavy use of biocides for the treatment of objects made of organic materials in museum collections (e.g. ethnographic, historical collections) was very common. Now suitable decontamination methods/technologies are being sought. A decontamination treatment by li-CO₂ was optimized that considered the specific requirements of museum objects. The treatment was tested on model materials artificially contaminated with biocide solutions containing dichlorodiphenyltrichloroethane (DDT), pentachlorophenol (PCP), lindane, and permethrin or cypermethrin. High decontamination was achieved for DDT, lindane, PCP, and permethrin on artificially biocide loaded wool and wood model materials. Optimal process parameter settings for li-CO₂ decontamination include a single 30?min cycle for woolen materials and three sequential 30?min cycles each for wood. These methods allow a reduction of at least 90% of all biocides for wool and between 70% and 85% for wood. Decontamination of the latter was more effective for less polar biocides as DDT and permethrin. Despite a significant improvement in decontamination for wood using co-solvents such as acetone, ethanol, and methyl tertiary-butyl ether (MTBE), their use is not recommended due to the increased risk of damage to the objects, in particular if a surface coating is present.  相似文献   

Experimental and Numerical Analysis of a Novel Display Case Design: Case Study of the Renovated Anne Frank House

ABSTRACT

Many museums are housed in historic buildings, sometimes the building itself is part of the museum collection. Creating a stable environment by providing a nearly constant temperature and relative humidity at correct levels decreases the risk of object degradation. Maintaining this steady indoor environment, however, increases energy consumption and risks to the historic building. Museum display cases offer a solution to the mitigation of risks to which valuable objects may be subjected by providing an extra layer of protection to indoor climate fluctuations. The Anne Frank House is a historic house museum located in Amsterdam. The museum has undergone several renovations in the last years to deal with an increase in the number of visitors to over 1.2 million a year. The original diaries and other documents of Anne Frank are permanently on display in the Anne Frank House. With the recent refurbishment the possibility arose to design a new state-of-the-art display case. This study presents the results of the experimental research related to the design, performed in-situ. The temperature and relative humidity in the new exhibition space and inside the new display cases were monitored to gain insight into the hygrothermal behavior of these controlled environments. A complementary numerical study was performed to investigate effects of dynamic climate control of the exhibition gallery and climate conditions in the display case under various circumstances. Four main conclusions are presented in this paper. The investigated display case design is able to provide a stable relative humidity environment by means of silica gel, while using an active box-in-box climate control system to create stable temperature conditions. The inner case temperature depends on the temperature supplied by the display case air handling unit. Protocols must be in place in case of malfunction or failure of the climate control system of the display case. The air handling unit of the case needs to be shut off to create a passive environment for the objects on display until necessary actions are taken. Exhibition gallery set points can be less stringent when susceptible museum objects are on display in the display case. The environments are separated and provide an opportunity for energy saving set point strategies. The last conclusion drawn is that the numerical study provides valuable insight into imposing dynamic control of set points for temperature and relative humidity in the exhibition gallery and the effect on the display case environment.  相似文献   

The work of the audience: visual matrix methodology in museums     

Lynn Froggett  Lizzie Muller  Jill Bennett 《Cultural Trends》2019,28(2-3):162-176

ABSTRACT

Visual matrix methodology has been designed for researching cultural imaginaries. It is an image-led, group-based method that creates a “third space” research setting to observe audience groups re-enacting lived experience of an event or process that takes place in the third space of a cultural setting. In this article, the method is described through its use in relation to an art-science exhibition, Human+ Future of the species, where three audience groups with investments in technology worked with exhibition material to achieve a complex ambivalent state of mind regarding technological futures. The visual matrix has been designed to capture the affective and aesthetic quality of audience engagement in third space by showing what audiences do with what is presented to them. We argue that such methodologies are useful for museums as they grapple with their role as sites where citizens not only engage in dialogue with one another but actively re-work their imaginaries of the future.  相似文献   

Negotiating the cultural and economic outcomes of sport heritage attractions: the case of the National Baseball Hall of Fame     

Gregory Ramshaw  Sean Gammon  Felipe Tobar 《Journal of Sport Tourism》2019,23(2-3):79-95

ABSTRACT

Contemporary museums must balance their roles as commercial entities and repositories of various, and often dissonant, heritages and histories. Sports museums in particular often have clear commercial and nostalgic aims, particularly through tourist visitation, though the extent to which they represent more challenging narratives remains unclear. This paper examines how one of the most famous sports museums in the world, the National Baseball Hall of Fame (NBHF) in Cooperstown, New York, balances its dual role as tourist attraction and repository of baseball's sometimes checkered past. It was found that different sections of the museum provide greater or lesser degrees of engagement with more controversial issues, although the commercial outputs and appeal of the museum remains clear throughout. Utlimately, the NBHF demonstrates that balancing veneration and critique in collections can be commercially prosperous, and can provide a template for other sport and popular culture museums who may be wary of incorporating more challenging narratives in their exhibits. Furthermore, the symbiotic relationship between the Hall of Fame and the village of Cooperstown, particularly in creating and maintaining cultural and economic outputs, requires further exploration.  相似文献

刘则晴 《自然科学博物馆研究》2017,2(4):37-43

闭环设计是指根据设计目标进行设计后,对已设计完成的方案进行目标确认,以检验其是否吻合并实现了设计目标。科技博物馆主题展览设计中,设计方案偏离原展览目标、原展览主题的情况常有存在。因此,本文在主题展览设计中引入“闭环设计”模式,探讨展览目标、展览主题的制定与实现,并以“宁波市公共安全宣传教育基地”展厅为例,讨论闭环设计在主题展览设计中的实际应用。  相似文献

论学术研究在主题展览中的基础性作用 ——以“鸦片战争”展览为例          下载免费PDF全文

唐立鹏 《自然科学博物馆研究》2017,2(4):5-11

历史文化类展览的主题,须从历史文化事实中提取最具代表性、影响力和教育意义的概念,并以丰富的历史文化内容来表达,通过承载着这些历史文化信息的展品和布展设计来表现。因此,学术研究是博物馆展览设计的基石,研究的广度和深度直接影响展览的科学品质。鸦片战争博物馆针对本馆的展览选题,搭建了包括馆刊、专著、论坛在内的多种学术平台,孵化了一批学术研究成果,并运用于“鸦片战争”展览,极大地深化了展览主题、丰富了展示内涵,并促成了形式与内容的较好融合,集中体现了“内容为王”的办展理念。  相似文献   

通过“二次开发”加强展品教育功能的有效性          下载免费PDF全文

葛宇春 《自然科学博物馆研究》2017,2(2):40-47

展品是科技馆有别于其他教育机构的主要教育资源,但如果展品仅是单纯展示而不辅之以必要的教育活动,其教育功能往往难以充分实现。通过考察分析和开发教育活动的实践,笔者认为:欲充分实现展品的教育功能,引导观众深入思考、主动探索,须通过教育活动对其教育资源进行“二次开发”。本文主要介绍了科技馆展品“二次开发”的概念、必要性、类型,并结合具体案例论述了其实现的方法与途径。  相似文献
