Due to the rapid development of Information and communication, the technology of multimedia presentation technology is evolving into the service that user can actively, realistically enjoy and play based on user's preference and taste not only for User's passive service. Especially, the industry related the realistic multimedia service that supports targeting Human emotion with the property of Human hearing is expected to be formed of the high value-added premium market. Audio technology is affected on human's emotion and the viewing environment around than video technology. Also the audio technology compared to video technology is a research part that appeals to human emotion and emphasize on psychological aspects. With this viewpoint, the development of intelligent and realistic audio technology needs highly specialty. In this study, "intelligent real-sound presentation technology" that support high quality and realistic audio and the "core technologies" that are composing of this will be introduced.

This study was carried out to investigate quality characteristics of jelly added with aronia juices. Aronia juices were incorporated into jelly at 0%, 10%, 20%, 30%, 40% and 50%. The total phenolic content, anthocyanin content and DPPH free radical scavenging activity of jelly increased with each increase of aronia juice contents (p<0.05). The moisture content and pH of jelly decreased, but soluble soild contents and the total acidity of the jelly increased significantly with each increased level of aronia juices (p<0.05). As the content of aronia juices increased, L values decreased while a and b value increased (p<0.05). Texture analysis showed that the mechanical properties of the jelly decreased with increased level of aronia juices. Consumer acceptability showed that aronia juices groups of 30% and 40% scored higher in terms of overall preference, color, and flavor compared to the other groups (p<0.05). Characteristic intensity rating of aronia jelly showed that as more aronia juices was added, it began to intensify its purple color as well as its sour taste (p<0.05). Judging from the results, it can be concluded that the addition of aronia juices to jelly in processing can enhance the preference, antioxidant compounds, and DPPH free radical scavenging activity of the jelly.

기존 스네이크 알고리즘은 에너지 함수의 정의에 의해 복잡한 객체의 윤곽을 추출하는데 어려움이 있고, GVF 방법은 에너지 맵 계산 시간이 많이 소요되는 문제점이 있다. 본 논문에서는 빠르고, 복잡한 객체의 윤곽을 잘 추출하는 방법을 제안한다. 객체 윤곽의 복잡도는 곡률로 정의하여 곡률 값이 임계치 이상이면 스네이크 포인트를 추가하여 객체의 윤곽을 추출하였다. 다수의 복잡한 영상에 실험을 통해 계산속도 및 윤곽 추출 성능을 개선하는 결과를 보여준다.

Korea Institute of Geology Mining and Materials(KIGAM) has been operating Korean Earthquake Monitoring System(KEMS) to archive the real-time data stream and to determine event parameters (epicenter origin time and magnitude)by the automatic processing and analyst review. To do this KEMS uses the Vindel Hue's velocity model which was derived from Wonju KSRS data. Because KIGAM now receives the real-time data from many stations including Wonju KSRS Cholwon seismo-acoustic array Uljin Wolsung Youngkwang Taejon Seoul Kimcheon Taegu etc. the proper velocity model should be established around the Korean peninsula, In this study P were velocity structures was derived from VELEST program using 69 events among the 835 events determined by KEMS in 1999 which were recorded by at least 5 stations. General trend of velocity structure was similar to Sang Jo Kim's model but velocity value was low in crust and high in upper mantle. Due to the sensitivity of inversion results to the initial input model the artificial short and blast data might be added.

Lignocellulosic biomass conversion to biofuels such as ethanol and other value-added bio-products including activated carbons has attracted much attention. The development of an efficient, cost-effective, and eco-friendly pretreatment process is a major challenge in lignocellulosic biomass to biofuel conversion. Although several modern pretreatment technologies have been introduced, few promising technologies have been reported. Microwave irradiation or microwave-assisted methods (physical and chemical) for pretreatment (disintegration) of biomass have been gaining popularity over the last few years owing to their high heating efficiency, lower energy requirements, and easy operation. Acid and alkali pretreatments assisted by microwave heating meanwhile have been widely used for different types of lignocellulosic biomass conversion. Additional advantages of microwave-based pretreatments include faster treatment time, selective processing, instantaneous control, and acceleration of the reaction rate. The present review provides insights into the current research and advantages of using microwave-assisted pretreatment technologies for the conversion of lignocellulosic biomass to fermentable sugars in the process of cellulosic ethanol production.

Despite is product that ship, vehicles, development equipment and Metal Bearing for plant equipment that is mass-produced by present domestic companies Cast White Metal Lining Bearing that is Bimetal Bearing standing 2 generation is accomplishing master and servant and this is foreseen to be used widely on industry whole in hereafter but Cast White Metal Bearing need minuteness processing, while price competitive power is depending on income from superior another thing area than itself manufacture already in advanced nation to lowdown that the technique is generalized widely, when take into account technology change aspect of industrial technology developing country, Go added value creation by deepening of price competition is judged to be difficult hereafter. Because domestic production and supply are wholly lacking almost in Metal Bearing Cladding that take advantage of these technology, Data-base about connection technology is weak with technique and Know-How for product. This research unites Back Steel and Aluminium Alloy different kind metal and make the Clad river studying technology about union of Gogangseong Dacheung metal bearing hereupon.

Location-based services are a recent concept that integrates a mobile device's location with other information in order to provide added value to a user. Although Location-based Services provide users with comfortable information, it is a complex task to manage and share heterogeneous and numerous data in decentralized environments. In this paper, we propose the Semantic LBS Model as one of the solution to resolve the problem. The Semantic LBS Model is a LBS middleware model that includes an ontology-based data model for LBS POI information and its processing mechanism based on Semantic Web technologies. Our model enables POI information to be described and retrieved over various domain-specific ontologies based on our proposed POIDL ontology. This mechanism provide rich expressiveness, interoperability, flexibility in describing and using information about POls, and it can enhance POI retrieval services.

Domestic production of agricultural machinery has come to be seen as appropriate entry route in the capital goods industry for most African countries, including Ghana, which has purely and strongly agricultural -based economics with a weak industrial infrastructure. Recent studies in Ghana do indicate that in addition to possessing technological capability in the manufacture of handtools, there is evidence of increased production of machinery for the primary food processing sector. Local manufacture of tractors and associated implements is embryonic, with an average domestic production of agricultural machinery in Ghana and analyses the available technologies and economic indicators in the local agricultural machinery industry. Areas for indicators in the local agricultural machinery industry. Areas for future development are identified.

Coffee chaff for manufacturing of the 6 mm thick cement-bonded boards was obtained from a coffee processing industry at Omuo-Ekiti, in Ekiti State, Nigeria. Boards were produced with three levels of cement to coffee chaff ratio of 1.5:1, 2.5:1 and 3.5:1; and at three levels of mixing curing reagent of 2.0%, 2.5% and 3.0%. Three dimensional properties of thickness swelling (TS), water absorption (WA) and linear expansion (LE) were investigated after 48 hours immersion in water. The mean values obtained for TS, WA and LE ranged from 0.46% to 1.47%, from 11.52% to 24.00%, from 0.19% to 0.35%, respectively. The most dimensionally stable boards were produced at the highest mixing levels of curing reagent and cement to coffee chaff ratio of 3.0% and 3.5:1, respectively. The coffee chaff is suitable as raw material for the manufacture of cement-bonded composites and it would be able to stimulate and activate the use of other agro-byproducts for the manufacture of value-added panels.
