  • In this study, different methods to coat honeycomb and metal foam substrate with platinum/titania for removing odor gases and volatile organic compounds were investigated. Among them, the powder coating and the nano coating were compared. Scanning electron microscopy/energy dispersive X-ray spectroscopy (SEM/EDX) analysis was used to investigate the surface conditions and exposed platinum composition ratios on honeycomb and metal foam. Also, the catalytic oxidation performance of toluene, trimethylamine and isopropyl alcohol was compared according to the coating method.

  • HTML로 표현된 양식은 데이터 모델을 포함하고 있지 않기 때문에 종이 양식과 같은 전자상거래 레코드를 구성하기 어렵다. XML로 양식을 표현하기 위한 노력은 XFDL이 대표적이다. 전자상거래 언어로서 XFDL의 가치는 데이터, 표현, 계산규칙, 의미 등에 대한 정보를 단일한 XML 문서에 통합하는 능력이 있다. XFDL은 고품질의 배치(Layout), 문서화(Documentation) 지원, 통합 계산, 입력 검증, 복수의 중첩되는 디지털 서명, 감사가 가능한 거래 레크드 등을 지원한다. 그러나, 이러한 특징을 갖는 XFDL은 내용과 표현을 분리하고자 하는 W3C의 정책과는 괴리가 있다. XForms는 HTML 양식의 한계점을 개선하기 위해서 W3C에서 활발히 추진되고 있는 XML기반의 차세대 양식이다. 핵심 아이디어는 사용자 인터페이스와 표현을 데이터 모델과 논리로부터 분리시켜서, 하나의 폼을 이동단말, 텔레비전, PC등 다양한 용도로 사용할 수 있도록 지원한다는 점이다. 이 논문에서는 차세대의 양식 표준으로 예상되는 XForms를 중심으로 기업간의 양식 처리를 위한 방안에 대하여 논한다.

  • The purpose of this study is to explore the present and future agricultural extension system and international cooperation systems for agricultural technologies in Ghana. The role of agricultural extension in the next decade should be quite different from what it was 10 years ago or even now. Its role as a facilitator of agricultural knowledge system would only increase as more participants from private sector would get involved in extension. The public sector extension would still continue to be the major extension provider in most parts of the country as the private sector alone would not be able to meet even partially the varied needs of farmers. Internal reforms are thus going to be the greatest challenge for the Ghana Extension System. The cooperation systems work in partnership with other stakeholder to provide agricultural extension and advisory services to farmers. Innovations (information/knowledge) emerging from the seed industry may be seen as dynamic and systemic process which can emerge from many sources. KAFECI's interventions must be flexible to accommodate such changes if the need arises in subsequent years (year 2 & 3). The framework and tools for technology transfer and dissemination is developed on "innovation platform" where a group of stakeholders/collaborators with diverse social and economic backgrounds, work towards a common objective or challenge.

  • In this study, volatile compounds in nine commercial Japanese distilled liquors (Shochu) were isolated by headspace solid-phase microexrraction (SPME) and analyzed by gas chromatography (GC) and GC-mass spectrometry (MS). A total of 76 volatile components, including 48 esters, 13 alcohols, and 15 miscellaneous components, were identified. Esters and alcohols constituted the largest groups of quantified volatiles. Differences in volatile components among the distilled liquors and possible sample grouping were examined by applying principal component analyses to the GC-MS data sets. The first and second principal components explained 77.92% of the total variation across the samples. The samples using barley koji showed higher overall concentrations of total volatile components. Additionally, the principal component analysis did not reveal any sample grouping based on the raw material used.

  • Software development creates many product that class components, Class Diagram, form, object, and design pattern. So this Paper suggests Index/XML Sequence Relation information system for product abstraction and classification, the system of design product Sequence Relation abstraction which can store, reuse design patterns in the meta modeling database with pattern Relation information. This is Index/XML Sequence Relation system which can easily change various relation information of product for product abstraction and classification. This system designed to extract and classify design pattern efficiently and then functional indexing, sequence base indexing for standard pattern, code indexing to change pattern into code and grouping by Index-ID code, and its role information can apply by structural extraction and design pattern indexing process. and it has managed various products, class item, diagram, forms, components and design pattern.

  • An oleaginous fungus was isolated from soil and identified as Mortierella sp. (M-12) for producing arachidonic acid (AA). Cell disruption methods, extraction methods, and particle sizes of freeze-dried biomass were tested to achieve maximum extraction of total lipids and AA. M-12 grown in glucose yeast media at $25^{\circ}C$ for 7 days contained 35.5% total lipid, and 47% of the total lipid was AA. Lipid extraction yield from wet biomass was shown to be similar to that in a dry state. Maximum lipid extraction was achieved using a mixture of chloroform and methanol (2:1) as an extraction solvent. Different mechanical cell disruption methods did not affect lipid extraction yields. The smaller the particle size of the biomass, the better the lipid extraction yield was observed. Particle size of biomass was shown to more strongly affect lipid extraction than extraction time. The highest AA content was observed in the class of neutral lipids.

  • This work investigated the plasma-catalytic decomposition of isopropyl alcohol (IPA) and the behavior of the byproduct compounds over monolith-supported metal oxide catalysts. Iron oxide ($Fe_2O_3$) or copper oxide (CuO) was loaded on a monolithic porous ${\alpha}-Al_2O_3$ support, which was placed inside the coaxial electrodes of plasma reactor. The IPA decomposition efficiency itself hardly depended on the presence and type of metal oxides because the rate of plasma-induced decomposition was so fast, but the behavior of byproduct formation was largely affected by them. The concentrations of the unwanted byproducts, including acetone, formaldehyde, acetaldehyde, methane, carbon monoxide, etc., were in order of $Fe_2O_3/{\alpha}-Al_2O_3$ < $CuO/{\alpha}-Al_2O_3$ < ${\alpha}-Al_2O_3$ from low to high. Under the condition (flow rate: $1L\;min^{-1}$; IPA concentration: 5,000 ppm; $O_2$ content: 10%; discharge power: 47 W), the selectivity towards $CO_2$ was about 40, 80 and 95% for ${\alpha}-Al_2O_3$, $CuO/{\alpha}-Al_2O_3$ and $Fe_2O_3/{\alpha}-Al_2O_3$, respectively, indicating that $Fe_2O_3/{\alpha}-Al_2O_3$ is the most effective for plasma-catalytic oxidation of IPA. Unlike plasma-alone processes in which tar-like products formed from volatile organic compounds are deposited, the present plasma-catalyst hybrid system did not exhibit such a phenomenon, thus retaining the original catalytic activity.
