  • This research was to investigate the adsorption characteristics of charcoals of major Korean wood species (thinned trees) and wood-based materials. As carbonization time and temperature increased, methylene-blue adsorption (MBA) of charcoals of thinned trees and wood-based materials increased. Pinus koraiensis charcoal showed the highest MBA. MBA of softwoods was higher than that of hardwoods. There was a negative correlation between air-dried specific gravity before carbonization and MBA of carbonized thinned trees. The MBA of wood-based materials showed similar value, but wood-based materials in MBA was lower than thinned woods. Surface area and total pore volume of thinned trees and wood-based materials increased as carbonization temperature increased. The species showing highest MBA appeared to have the highest surface area at the carbonization temperature of 600℃ as well. There was a positive correlation between surface area, total pore volume and MBA of charcoals. The charcoal of wood-based materials generally exhibited micro pores.

  • Master of Business Administration (MBA) education is growing rapidly in China, while many business schools in Japan are having difficulty in recruiting new students. The MBA education in China and Japan followed a different course and showed very different trends. In this article, we make a comparative study of MBA education in China and Japan. The emphasis is put on analyzing the reasons that caused the difference in the MBA education in the two Asian countries. We trace back the development of MBA education in China and Japan, examining the MBA education from the viewpoint of social environment, enterprise culture, and government support and control as well as the incentive and faculty management system of universities.

  • VOD(Video-On-Demand) 시스템에서 제한 없는 VCR 서비스는 클라이언트들의 개별 서비스 요청에 대하여 유일한 비디오 스트림을 할당함으로서 제공될 수 있다. 이 방식은 서버 부하의 증가와 부족한 네트워크 자원의 고갈 등과 같은 중대한 문제점을 갖고 있으나 클라이언트의 셋톱박스에 버퍼를 구현함으로서 매우 제한된 VCR 기능을 제공하게 된다. 본 논문에서는 대화형 VOD 시스템에서 제한 없는 VCR 기능을 제공할 수 있는 새로운 MBA(Multicast Buffering Algorithm) 알고리듬을 제안한다. MBA 알고리듬 하에서 VCR 서비스는 버퍼가 동적으로 확장되어 비디오 데이터를 저장하기 때문에 사용자에게 제한 없이 제공되어진다. 또한 MBA 알고리듬은 버퍼의 사용 효율을 증대시키는 방법을 제공하며 모든 클라이언트들의 서비스 요청을 지연 없이 즉시 처리하므로 사용자들에게 진정한 대화형 VOD 서비스를 제공하게 된다. 본 논문에서는 MBA 알고리듬을 이용하여 지연 없는 VCR 기능을 갖춘 VOD 서비스를 구현하였으며 시뮬레이션 결과는 MBA 알고리듬이 다른 버퍼링 방식과 비교하여 매우 우수한 성능을 갖고 있음을 보여주고 있다.

  • We investigated the physiological activities of extracts from Campbell Early and Muscat Bailey A (MBA) grapevine leaves. Total phenol and flavonoid contents were highest in ethanol extracts from MBA grapevine leaves compared to extracts from Campbell Early grapevine leaves. Specific polyphenols higher in ethanol extracts from MBA grapevine leaves include gallic acid, epicatechin, caffeic acid, naringin, and resveratrol. Resveratrol content from MBA grapevine leaves increased when extracted for more than two hours in ethanol and water. The hydroxyl radical scavenging ability of ethanol extracts was higher than the water extract from both strains of grapevine leaves. DPPH and total antioxidants were highest in ethanol extracts from MBA grapevine leaves among the other extracts. Therefore, these results suggest that ethanol extracts from MBA grapevine leaves are a highly valuable resource for the development of natural functional foods.

  • The ethanol solvent extracts obtained from the pulp, skin, seeds, leaves, fruit stems, and pruning stems of four Korean new grape varieties ("Dunoori", "Narsha", "Cheongsoo", and "Heukbosek"), as well as "Campbell Early", and "Muscat Bailey A (MBA)" were evaluated for their total phenolic and anthocyanin contents. The concentrations of four phenols of biological interest, catechin, epicatechin, quercetin, and resveratrol in the different parts were quantified by high-performance liquid chromatography-ultraviolet analyses. The skin of "Narsha" and "Heukbosek", the leaves of "Narsha", the fruit stems of "MBA", and the pruning stems of "Campbell Early" and "Heukbosek" had the highest resveratrol content. In particular, the resveratrol in the fruit stems of "MBA" had the highest concentration as compared to the other varieties in the different parts. The seeds of "MBA", and the fruit stems of "MBA" and "Heukbosek" had the highest catechin content. Epicatechin was detected in the seeds, fruit stems, and pruning stems. Quercetin was detected only in the leaves. In summary, the catechin and epicatechin contents were significantly higher than the quercetin and resveratrol contents. The concentrations of the physiologically active components present in the grapes were high in the non-edible parts than in the edible parts; therefore, they could be useful in industrial applications.

  • This study was designed to test the effects of enzyme treatments on the extraction of total phenolic compounds and on color characteristics in wines from domestic MBA(Muscat Bailey A) grapes. The total phenolic compound content of the MBA grape wine was $1,352.8{\pm}37.8\;mg/{\ell}$ at 10 days of fermentation. Furthermore, MBA wines treated with 2%(v/v) of Pectinex and Viscozyme had 14.5%(p<0.05) and 3.8% increase, respectively, in total phenolic compound content by 10 days of fermentation. Pectinex treatment was more effective for phenolic levels than Viscozyme treatment. The L, a and b values of the MBA grape wine were 7.4, 9.2 and -1.2, respectively, by 10 days of fermentation. The values in case of Pectinex enzyme treatment were 7.0, 10.6 and -0.8, respectively, and these values were significantly different according to Pectinex treatment(p<0.05). But the values in case of Viscozyme enzyme treatment were 7.2, 9.8 and -1.1, respectively, and these values were not different according to Viscozyme treatment. The hue and color intensity values of the MBA grape wine were 0.492 and 0.785, respectively, by 10 days of fermentation. The values in case of Pectinex enzyme treatment were 0.460 and 0.881, respectively. And as a result of the Pectinex treatment, the hue value of wine was decreased and color intensity was increased slightly(p<0.05). But the values in case of Viscozyme enzyme treatment were 0.482 and 0.805, respectively, and these values were not different according to the Viscozyme treatment.

  • It is most important for distribution center in retail business to delivery commodities in a timely manner. Accordingly, many companies try to make distribution center effective using the Warehouse Management System(WMS) integrated legacy system. Also, the Customer Relationship Management(CRM) is the most typical paradigm in management lately. Even though the WMS and CRM are independent system of each other, WMS, coupled with CRM makes customer satisfied more effectively. In this paper, we proposed the methodology for inventory location after analyzing and applying customer buying pattern data in the CRM through the MBA(Market Basket Analysis), which is part of data mining. We used an example modeling a real distribution center in retail through a 3D simulation tool and examined correlation between commodities using customer buying pattern. After that, we applied it to the inventory location system through the MBA in an example. Finally, we identified decrease in the time for picking, which is the majority of distribution center. Besides, we proposed a simulation methodology before applying new methodology. Consequently, it removes potential errors in advance and makes a optimized inventory location system.

  • 우리나라의 고령인구 수가 점점 늘어남에 따라 시니어 식품산업에 대한 관심이 높아지고 있다. 고령친화산업에 대한 연구는 "고령친화산업진흥법"이 제정된 2006년 이후 본격화되어 시니어 소비자, 의류, 금융 등 분야에서 연구되고 있으나, 시니어 식품산업에 대한 산업구조분석 연구는 미미한 실정이다. 본 연구에서는 미래 유망 성장 산업으로 기대되는 시니어 식품산업에 대해 마이클포터의 5 forces model을 적용하여 경쟁자를 파악하고, VRIO분석을 통해 내부자원을 분석하여 실질적인 시니어 식품산업의 경쟁력을 제고할 수 있는 전략을 도출하고자 한다. 이는 향후 관련 산업의 경제적 가치와 수요에 영향을 미치는 요인, 기업 내부 역량별 시장성 분석 등을 위한 기초 자료로 활용될 것이다.
