Progressive Freeze - Concentration ; a New Method for High - Quality Concentration of Liquid Food

Miyawaki, Osato 한국산업식품공학회 2001 산업 식품공학 Vol.5 No.3

Progressive freeze-concentration is a new concentration process in which only a single ice crystal is formed in the system so that the separation of the ice crystal from the concentrated mother solution is very easy. This makes the system much simpler to reduce the cost of freeze concentration substantially as compared with the conventional method of suspension crystallization. Principles, the method for scale-up, and expected applications of progressive freeze concentration is discussed in this review.

The Fukushima Nuclear Accident and Environmental Risk: A Survey of Fukushima Residents

Miyawaki, Takeshi,Sasaoka, Shinya Center for Asian Public Opinion ResearchCollaborat 2017 Asian journal for public opinion research Vol.5 No.1

The Fukushima nuclear accident caused by an earthquake and a subsequent tsunami on March 11, 2011 has seriously impacted the environment surrounding the Fukushima Daiichi nuclear power plant. While all the residents near the plant were evacuated from the area deemed uninhabitable after the accident, residents of the neighboring area outside of the evacuation zone still seem to live in fear of invisible radiation. To understand Fukushima residents' thinking about the environmental risks that accompany a nuclear disaster, we utilize a poll of the residents of Fukushima conducted in 2013. Based on the survey data, we reveal factors that seem to strongly affect their knowledge and concerns about nuclear power plants. The results of the multivariate analysis show the importance of the following two factors: (1) confidence in mass media, and (2) trust in institutions in charge of administering the accident, especially the central government, the Nuclear and Industrial Safety Agency, and Tokyo Electric Power Company. We conclude that the more people trust mass media and particular institutions, the more likely it is that they are have an elevated sense of anxiety and fear of the presence of nuclear plants.

화학적처리로 용출된 비산재의 매립지에서의 영향

최근 일본에서, 대부분의 도시고형폐기물은 소각 되어지며 불연성 폐기물 및 소각재는 매립되어진다.소각재는 바닥재 또는 비산재로 분류되어 지며, 비산재는 적지않은 중금속을 함유하며, 이것은 안정화 처리후 매립되어 진다. 그 결과 처리된 비산재의 중금속 침출수는 억제되어진다. 그러나 바닥재, 분쇄된 폐기물 그리고 용출된비산재의 공동처분의 영향에 대해서는 알려진바가 없다. 이 연구는 화학적으로 안정된 비산재 2가지 종류를 가지고 몇 년간 매립지내 공동처분과 침출수의 특성, 온도를 측정하였고 가스 구성에 관한 실험을 하였다. 실험에서 비산재, 유기 및 무기물, 화학적으로 안정된 비산재를 사용했으며, 혼합폐기물은 바닥재, 비산재, 분쇄폐기물과 퇴비로 만들었다. 침출수 특성은 처리되지않은 비산재(Lysimeter A), 화학적으로 안정된 유기 비산재(Lysimeter B) 그리고 화학적으로 안정된 무기 비산재(Lysimeter C)로 측정하였다. 실험결과 침출수의 중금속 농도는 pH, ORP 그리고 염도에의해 좌우된다. 이전 매립지에서 유출된 중금속은 많지만 유출비율로는 작다. In recent times in Japan, most municipal solid waste has been incinerated. Therefore, most landfill waste is incinerator residue and incombustible crushed waste. Incinerator residue can be classified as either incinerator bottom ash or fly ash. As fly ash contains considerable amounts of heavy metals, it is landfilled after the legaly-required stabilizing treatment. As a result, heavy metal leaching from treated fly ash is inhibited. However, it is not known what influence the co-disposal (mixed disposal) of bottom ash, crushed waste and fly ash has on the leachate. In this study, we have continued to experiment with two types of chemically stabilized fly ash using a large-scale lysimeter that simulates landfill co-disposal, and measured leachate quality, temperature and gas composition over several years. In this experiment, we used untreated fly ash, and both organic and inorganic chemicaly-stabilized fly ash. Mixed waste was made from bottom ash, fly ash, crushed waste and compost. Leachate quality from the lysimeter with the untreated fly ash (Lysimeter A), the lysimeter with organic chemically-stabilized fly ash (Lysimeter B) and the lysimeter with inorganic chemically-stabilized fly ash (Lysimeter C) were measured. Experimental results show that the extent of heavy metal leaching depends on pH, ORP, and salt concentrations. Heavy metal effluence abounds in the early periods of landfilling and that the rate of effluence was small.

INFLUENCE OF LANDFILLED CHEMICALY-TREATED FLY ASH ON LEACHATE QUALITY

Historical Importance of the Biography of Zaya Pandita

( Junko Miyawaki Okada ) 한국알타이학회 2005 알타이학보 Vol.0 No.15

The Biography of Zaya Pandita, titled “Tale called Moonlight of Rab'byams-pa Zaya Pandita”, was composed in the 1690's or somewhat later in present-day Dzungaria. Its author, Gelong gsol-dpon Radnabhadara, was a disciple of the first Zaya Pandita Nam-mkha'i-rgya-mtsho. Its story starts with the birth of the first Zaya Pandita in 1599. In 1615 he was chosen by Baibaghas, the Khoshuud chief, to be an adopted son and received commandments of a bande, when the Oyirad tribal chiefs became first Tibetan Buddhists under the political influence of their eastern neighbor, the Khalkha Mongols. He studied twenty-two years in Tibet from the next year 1616 and became a highest monk ever produced by the Oyirads. It was he himself who created in 1648 the Oyirad alphabet, or todorkhoi uzuq (clear alphabet), by improving the traditional Mongolian alphabet. His biography itself, except sutras translated from Tibetan, was the earliest source written in the Oyirad script. After his death in 1662, the story goes on to tell about the fate of his disciples who were waiting in Dzungaria for the arrival of his reincarnation born in Khara Khoto and was studying in Tibet. In 1687 the Oyirad and the Khalkhas were greatly disturbed, and while Galdan marched into the Khalkhas in 1688, there was a civil war in the kuree (mobile monastery) of Zaya Pandita. It is said in the end of the story that only one hundred men or so were left from the sevenhundred and fifty of the kuree after those killed in the war, those starved to death and those murdered by 1691. Nothing is said to what happened to the second Zaya Pandita. His kuree being totally destroyed, he must have stayed in Tibet and never returned to the land of the Oyirad. There exist no historical records like this that allows us an insight into the reality of the Oyirad community in the seventeenth century.
