Organic Acid Generation from Oxygen Scavengers Used for Anoxia Pest Control Method
Get PDFThe present research conducted an emergency examination on odor emission from K-type RP oxygen scavengers utilized in low oxygen treatment, as a report has been received that the oxygen scavengers emit organic acid while conducting the treatment. Using several 10 L oxygen impermeable film bags, the generation of organic acid were observed by checking the relevance of the number of oxygen scavengers enclosed and the period enclosed. As a result, it was found that the organic acid concentration tended to increase when the number of oxygen scavengers enclosed was less than the specified amount and the organic acid concentration tended to decrease as the number of enclosed oxygen scavengers increased. When a specified amount of oxygen scavengers was enclosed, the density of organic acid was 511 μg/m3, which is over the suggested density for exhibition and storage (< 430 μg/m3
).
From these results, it has been clarified that cultural properties are likely to be exposed to high concentrations of organic acids during insecticidal treatments using oxygen scavengers. In the future, it will be necessary to analyze the detailed components of organic acids generated from the oxygen scavenger and to study the production of organic acids for others. As a temporary conclusion, careful considerations should be made before using K-type RP oxygen scavengers for cultural properties vulnerable to organic acid.journal articl

Present Condition of Folk Cultural Properties in the Midst of Covid-19 and Their Issues
Get PDFThe present paper discusses the influence Covid-19 has had on the intangible folk cultural properties of Japan with focus on case studies from 2020. First, it is noted that many folk events are held in the hope of appeasing infectious diseases. For example, the lion dance in Hakone, Kanagawa Prefecture, was started as an event to ward off contagious diseases that occurred frequently from the last half of the 19th century to the first half of the 20th century. Social relevance of this type of folk events should be shared by many people.
Next, impact such as cancellation and postponement of folk events and measures like video delivery that were taken in 2020 are discussed in the section on the condition of intangible folk cultural properties in the midst of Covid-19. In this situation, much criticism has been voiced even about folk events that were held in order to pray for the end of infection. Such a trend connects to a questioning and negation of values associated with these folk events.
Finally, the problems related with intangible folk properties in the midst of Covid-19 are discussed. Intangible folk properties are one of the categories of intangible cultural heritage unique to Japan. It is different from traditional performing arts performed by professionals in that it is cultural properties of the “people.” It is rooted in the faith, society, entertainment and other aspects of a given region. But the influence of Covid-19, by negating their values, brings about a great risk to the regional society.departmental bulletin pape
Support for Intangible Cultural Heritage in the Midst of Covid-19
Get PDFThe new coronavirus infection, which was first confirmed at the end of 2019, has not yet been brought under control, with a cumulative number of approximately 80 million people infected worldwide, although there are some signs of hope, such as the commercialization of a vaccine. The impact of this coronary infection is spreading globally and affecting all areas of social life. The present paper focuses on intangible cultural heritage, especially traditional performing arts, and public support for them under such a situation.
The Japanese government’s support for the arts and culture sector, which was hit hard by the corona disaster, started a little late due to the unfavorable conditions at the turn of the fiscal year, but the budget has reached a certain scale that can be evaluated. However, it must be denied that the government’s support has given a sense of security to the recipients. In Germany, in March and April, the heads of the cultural administration and the federal government announced in their own words their strong support for the field of culture and the arts, and made it clear that this would be a top priority in the government’s measures against corruption. In fact, the government has been speedily implementing the support. In the case of Japan, by contrast, the following four points have hindered the effectiveness of the support.
1. Lack of clear emphasis on arts and culture
2. Lack of speed
3. Complicated procedures
4. Difficulty in understanding the information desk for support
All parties involved in culture and the arts have the right and the obligation to advocate to the government for further enhancement of public support and improvement of the current bottlenecks.departmental bulletin pape
Looking at Regional Heritage: Case Study of an Example from Eastern Hokkaido
Get PDFRecently there is a movement to look at and protect, as heritage of a region, nature and culture that have been transmitted throughout Japan. The present paper deals with an example from east Hokkaido as one of such case studies and discusses its issues and future.
Four autonomous bodies of east Hokkaido (Shibetsu-cho、Nemuro-shi, Bekkai-cho, and Rausucho) jointly nominated the “Story of the ‘Holy Land of Salmon’” to Japan Heritage in 2020. With “salmon” as common concept, this heritage includes the culture of both Ainu and Japanese people as its element. The attempt is deeply significant in that it aims to look at common heritage of the region which the Ainu and Japanese can share. There is possibility that heritage of a region can be employed as a tool to realize harmonious existence of people of different ethnic groups.departmental bulletin pape
Control of Green Organisms Grown on a Fossil at AmmoniteHouse, Amakusa City
Get PDFThe present study deals with an ammonite fossil conserved and utilized in situ in
Cretaceous sedimentary rocks in Ammonite House, Amakusa City, Kumamoto Prefecture. After the public opening of Ammonite House which has translucent ceilings and walls, the fossil surface became covered with green organisms such as algae. Though the interruption of sunlight was tried by putting a lid on the observation window, the effect could not be evaluated sufficiently because of accidental surplus lighting during a repair of the House. After that, existing halogen lamps for visitors were replaced with daylight color LED lamps, and the illumination at the fossil surface was accordingly reduced. Asaresult, the annual estimate illumination at the fossil surface became low enough into the order of 10−4 lxh/y. It was finally confirmed that the green organisms were reduced significantly on the fossil surface to be inspected as clearly as before.journal articl
Study on Conservation Environment in a Storage Facility without Air Conditioning Equipment: The Case of Seki Kasuga Shinto Shrine, Gifu Prefecture
Get PDFIn the present paper, as a case study of humidity control and biological damage
countermeasures in a storage facility without air conditioning equipment, temperature and humidity surveys were conducted and the effect of dehumidification for environmental improvement of the Shimpoden at the Kasuga Shinto Shrine in Seki City, Gifu Prefecture was tested. It was confirmed that improper ventilation system caused an increase in internal humidity, and a decrease in humidity was confirmed to some extent by removing the ventilation fan and closing the ventilation port in Shimpoden.
Since Shimpoden is a storage facility that is always closed, it was not possible to introduce a dehumidifier that requires drainage management, but with the introduction of a desiccant dehumidifier that can use ventilation openings, a further reduction in humidity was achieved. Additionally, it was possible to maintain a relative humidity of 55% ± 5% throughout the year, which is the suggested environment in which molds would hardly grow. The condition of mold damage at the start of the survey has improved significantly, and now mold is hardly observed visually.journal articl
