Hideyuki Shimaoka 한국당과학회 2018 한국당과학회 학술대회 Vol.2018 No.01
Due to the significant growth of glycan-related research field, especially in the biopharmaceutical industry, commercially available tools for glycan structural analysis and glycan interaction assay are highly required. In this presentation,@three kinds of glycan research tool will be introduced: IgG glycan sample preparation kit EZGlyco® and versatile glycan purification kit BlotGlyco®as well as Glycan Microarray for high-throughput glycan interaction assay tool.

현재 일본에서는, 매립지의 부지 확보가 어려워지고 있기 때문에, 복토재료의 이용 용적을 감소함으로써, 매립지의 수명을 연장시키는 데 관심을 갖고 있다. 본 연구는, 복토토양을 대신하여 사용될 수 있다고 여겨지는 복토대체재료에 관하여 이루어졌다. 오염물질의 거동을 해석하기 위해 두 개의 모형매립조가 설치되었고, 복토재료로는 폐지가 사용되었다. 장기 실험을 통해, 침출수의 발생량 특성(용적, 양)에 대한 여러 복토재료의 영향을 파악하였다. 토양을 적용한 복토층의 경우, 매립조 내에서 액상의 이동에 대해 채널링을 유발하였고, 이는 폐기물의 안정화(오염물질의 분해 및 세척효과에 의한)가 지연되는 것으로 조사되었다. 한편, 복토재료로서의 기능을 갖춘 대체 복토재료를 얇은 두께로 적용했을 경우, 안정화 기간을 줄일 수 있는 것으로 조사되었다. It is currently exceedingly difficult to obtain land for a new landfill site in Japan and towards prolonging the effective life of existing landfill sites by decreasing the volume consumed by the volume of cover soil materials, research is being conducted into an alternative material that may be used in the place of cover soil. This study utilized two dimensional large simulated landfill lysimeters replicating the cell method in order to elucidate the behavior of pollutants in waste landfill sites when used paper is utilized as alternative to cover material. The long term experiment was undertaken to determine the impact of different cover materials on the characteristics of the discharge flow (volume and quality) of the leachate. As a result of this experiment, it was found that a cover layer composed of soil causes channeling in the movement of liquid within the landfill thus creating a region in which the stabilization of the waste (washing out and degrading of pollutants) is retarded. On the other hand, an alternative cover material that allows a thinner cover layer while providing the functions required of cover material was found to mitigate the delayed stabilization.

Hydrogen Generation Potential in MSW Incinerator Bottom Ash
( Nithiya Arumugam ),( Takayuki Shimaoka ),( Amirhomayoun Saffarzadeh ) 한국폐기물자원순환학회(구 한국폐기물학회) 2014 한국폐기물자원순환학회 심포지움 Vol.2014 No.1
In this study, the feasibility of bottom ash in hydrogen generation was evaluated based on the aluminium-water based reaction. Bottom ash products which collected from two incineration facilities in Japan (R and N) were analysed for hydrogen production. Samples were grouped into two particle size fractions (1≦d≦2mm and 2≦d≦4.75mm). Samples from facility N showed seven to nine times higher hydrogen production compared to plant R samples. Smaller fraction of N samples (1≦d≦2mm) showed 1.2 times higher hydrogen generation than bigger particles (2≦d≦4.75mm). The pH of all four samples remains in the alkaline condition throughout the experimental period.

Immobilization effect of chelate treatment was investigated using leaching experiments. Chemical forms of immobilized heavy metals in chelate treated municipal solid waste incineration (MSWI) fly ash were also investigated. Leaching experiments showed that heavy metals in chelate-treated MSWI fly ash are immobilized except for Cu. Some of Cu was incorporated into crystal structure of ettringite generated by chelate treatment. However, immobilization effect by ettringite might be limited. Chemical forms of heavy metals in chelate-treated MSWI fly ash seems to be oxides, sulfate or chlorides. Heavy metal particle sizes are several ten μm scale and concentrated spots of heavy metals were not mostly observed. Therefore, heavy metals seem to be distributed widely and tenuously on fly ash particle.

Objectives: The purpose of this study is to examine relationship between an amount of key tasks and job satisfaction among caregivers and nurses in elderly care facilities. Methods: Questionnaires were mailed to the caring staff of elderly care facilities. After data collection (return rate 70%), information about work situations and health conditions were analyzed among 325 female workers, who were classified to 4 groups as follows; (1) caregivers under 40 years of age (2) caregivers of 40 years or over (3) nurses under 40 years of age (4) nurses of 40 years or over. Results: Mean ages and length of career in caring sector were 37.2 ± 12.2 yr and 4.5 ± 3.0 yr for caregivers and 41.6 ± 9.2 yr and 16.8 ± 8.9 yr for nurses, respectively. A larger amount of care services were done on average by workers being dissatisfied with their job than by the satisfied workers in each of the 4 groups. The dissatisfied caregivers under 40 years showed significantly higher frequencies (as ratios of 1.4 - 2 to 1) in several care services such as “helping with showers or baths”, “helping with eating”, “changing diapers”, “moving caretakers from bed or chair to wheelchair or vice versa”, as compared with the satisfied caregivers under 40 years. Similarly, the 40 plus dissatisfied caregivers helped caretakers sit up in bed significantly more frequently. For nurses, on the other hand, “changing diapers” was found as the only service with a significant difference in frequency between the dissatisfied and the satisfied, but that was limited in the 40 plus age group. A frequency of “changing diapers” was associated with an increase in the risk of job dissatisfaction. Conclusions: These results suggested that an appropriate amount of each key task in elderly care facilities should be set to prevent staff’s dissatisfaction with their job from growing excessively.
