PURPOSES : To ensure appropriate RCC properties with sufficient strength development and workability, it is necessary to secure a proper level of consistency. It is also necessary to secure maximum dry density, which is an important factor for increasing the interaction of aggregate interlocking, leading to an augmentation of RCC strength. On the other hand, the dry density of RCC can be changed owing to the compaction conditions, water content, and particle size distribution. A Proctor test and a modified Proctor test were used for determining the optimum water content needed to achieve maximum dry density with different amounts of compaction energy. A Vebe test, on the other hand, was used for checking the level of consistency, which is important for producing a workable mixture. METHODS : To confirm the degree of compaction at various particle sizes, RCC mixtures with different sand/aggregate ratios were evaluated. The Proctor test and modified Proctor test were applied to these mixtures to check the effect of the aggregate gradation and compaction energy on the maximum dry density and optimum water content. During each test, three specimens were produced for all types of water content under each aggregate gradation. A compaction curve and the optimum water content and maximum dry density for each aggregate gradation were then obtained for both tests. The range of water content for the appropriate consistency of each aggregate gradation was determined through a Vebe test. The optimum water content was then evaluated based on this range. RESULTS : The compaction test results show that the modified Proctor test provides a higher maximum dry density and lower optimum water content compared with the standard Proctor test. For the modified Proctor test, two cases of aggregate gradation (s/a = 30% and 70%) had the optimum water contents outside of the appropriate water content range. For the standard Proctor test, on the other hand, none of aggregate gradations provided the optimum water content within the desired range. CONCLUSIONS : The modified Proctor test should be used for an RCC mixture design because it can provide adequacy between maximum dry density and consistency. Moreover, the compaction roller has become highly developed for higher compaction energy.

This study was carried out to find out whether there exists any content variation in 1-deoxynojirimycin (DNJ) among regional and varietal mulberry leaves. HPLC analysis was performed for 22 samples collected from several localities in Korea and Tsushima Islands Japan. The highest content was observed in the Cheongilppong sample collected at Youngchun City, Kyungsangbuk Province (1,882.7 $\mu\textrm{g}$/g DW), whereas lowest content was observed in the Cheongilppong sample collected at Jiniu City, Kyungsangnam Province (395.65 $\mu\textrm{g}$/g DW). In the comparison of regional samples of Kaeryangppong variety, DNJ content was highest in the order of Woniu City (1,460.1) > Boungun (999.85) > Hweongsung-gun (939.12) > Cheongju City (688.78). In case of Cheongilppong, DNJ content was highest in the order of Youngchun City (1.882.8) > Sanchung-gun (1,125.3) > Sunchon City (649.17) > Byunsan-myon (441.54) > Jinju City (395.65). Average content of regional samples was higher in Kaeryangppong (1,021.7 $\mu\textrm{g}$/g DW) than that of Cheongilppong (898.87 $\mu\textrm{g}$/g DW). Average DNJ content of the wild mulberry loaves collected from Cheju Island and Tsushima Island (1,012.9$\mu\textrm{g}$/g DW) was high enough to reach to that of the regional Kaeryangppong samples. In the comparison among varietal samples collected in Suwon, the highest DNJ content was observed in YK209 (768.16 $\mu\textrm{g}$/g DW), amongst overall low DNJ content of the varietal samples. Considering a few pieces of information from our data, DNJ content appears not to be influenced solely by annual temperature of the planted areas.

The study was carried out to investigate water activity, physicochemical properties and color degree of burley tobacco stored in shelf with different moisture content for 56 days. The study was consist of two experimental designs, that is, moisture content in burley tobacco was kept to 13 to 15 %, 17 to 19 %, and 21 to 23 % under ambient temperature of $20^{\circ}C$ with relative humidity of 24 %, and another group of in burley tobacco was only kept in ambient temperature of $3^{\circ}C$ with relative humidity of 50 % for 56 days with same water content of former treatment. Normal leaves were kept for 56 days under 21 to 23% of moisture content with increased water activity and TSNA(tobacco-specific nitrosamine content. It was considered that favorable leaves conditions are due to favorable microbial growth resulting in increased TSNA content. The total nitrogen content has not changed in two experimental groups for 56 days, otherwise the nitrate form nitrogen and total alkaloid contents were only increased by 21 to 23 % of water content. Degree of pH change was slightly decreased in both storage and water treatment. It was more decreased in 21 to 23% of moisture content than that of other moisture content. In stored leaf tobacco, higher moisture content caused lower brightness, yellow degree, and carbonization quotient.

콘텐츠 중심 네트워크(CCN)는 데이터를 찾는데 필요한 라우팅 정보를 콘텐츠 이름에서 찾는 방식으로 기존의 IP 방식과는 다른 새로운 네트워킹 패러다임이다. CCN의 도전과제 중 하나인 이동성 관리는 크게 정보요청자의 이동과 정보제공자의 이동을 들 수 있다. 그 중에서도 정보제공자 이동의 경우 해당되는 라우터의 경로 정보를 갱신해야 하므로 많은 오버헤드와 시간이 필요하다. 이에 본 논문은 CCN에서 효율적인 정보제공자의 이동성 지원을 위해 콘텐츠의 인기도를 고려한 Popularity-based Pushing CCN(PoPCoN)을 제안한다. 제안하는 알고리즘은 기존의 기법과 비교하여 요청자의 콘텐츠 다운로드 시간을 단축시키고 네트워크의 오버헤드를 감소시킨다.

인터넷을 이용한 콘텐츠 공유를 보다 효율적으로 구현하기 위하여 P2P, CDN, CCN과 같은 다양한 네트워크 기술들이 개발되었다. 이러한 기술들은 공통적으로 콘텐츠 배포자에게 집중되는 콘텐츠 요청 패킷을 네트워크에 분산된 다수의 노드들/호스트들이 처리하도록 설계되어, 네트워크 병목 현상을 해결하고 콘텐츠 배포 시스템이나 네트워크 상태와 상관없이 지속적으로 콘텐츠를 배포할 수 있는 장점을 갖고 있다. 그러나 분산된 노드/호스트로부터 콘텐츠를 전송 받는 경우, 사용자가 실제 콘텐츠 전송 노드/호스트를 식별/인증할 수 없기 때문에 공격자 개입 및 악의적인 콘텐츠 변경을 통한 다양한 해킹 공격에 취약하다. 그러므로 분산 노드/호스트를 이용한 네트워킹 기술의 경우, 콘텐츠 인증 기술은 핵심 기술 요소들 중 하나이다. 본 논문에서는 CCN에 적용된 콘텐츠 인증 기술인 MHT 기반의 콘텐츠 인증 기법을 소개하고, MTH의 인증 정보 중복 전송 문제를 해결하고 전송량을 개선하기 위하여 인증 경로 계층 값을 최소화하는 방안을 제안한다. 또한, 기존 기술들과의 성능 비교를 통하여 개선안의 성능을 평가한다.
