본 논문에서는 유선망과 무선망 환경에 적합한 멀티캐스트를 게이트웨이 시스템을 개발하였다. 유선망과 무선망에서의 스트리밍 서비스를 제공하는 련도의 게이트웨이에 멀티캐스트 기법을 적용하여 유선망의 서버의 부하를 분산시키고 네트워크 대역폭 자원을 효율적으로 사용할 수 있도록 개발하였다. 실시간 영상 멀티캐스팅의 경우 동시에 같은 비디오의 동일 시점을 재생하고 있는 가입자들이 있을 때만 멀티캐스팅이 가능하다. 따라서 기존의 기법을 개선하여 본 논문에서는 멀티미디어 데이터 전송을 능동적으로 무선망에 적용하기 위하여 이에 적절한 Patching 기법을 적용하였다. 이를 통하여 유선과 무선망이 흔합된 단일망의 변화를 효율적으로 적용한 멀티캐스트 게이트웨이를 개발하였다.

New, thermally robust, arylenevinylene conjugated polymers, including poly(9,9-dioctylfluorenyl-2,7-vinylene) [poly(FV)] and poly[2-(3'-dimethyldodecylsilylphenyl)-1,4-phenylenevinylene] [poly(m-SiPhPV)], were synthesized and used for the fabrication of efficient photovoltaic cells. Bulk heterojunction photovoltaic cells fabricated by blending one of the polymers, [poly(FV)], [poly(m-SiPhPV)], and poly(FV-co-m-SiPhPV), with the fullerene derivative [6,6]-phenyl-$C_{61}$-butyric acid methyl ester (PCBM) were found to have a power conversion efficiency of up to 0.038%..

문화콘텐츠산업은 고부가 가치 창출 산업으로 최근 여러 대학들에서는 독립학과 신설 또는 학제간 공동과정으로 문화콘텐츠 인력양성을 추진하고 있다. 국내 J 대학 또한 2006년부터 6개 학과가 공동으로 문화콘텐츠 연계전공을 신설하여 운영하고 있다. 연계전공의 중요성에도 불구하고 지금까지 연계전공 강의나 관리에 대한 진단이나 연구가 드물다. 본 논문에서는 현재 J 대학에서 운영되고 있는 문화콘텐츠 연계전공 학생을 대상으로 연계전공 강의와 관리에 대한 만족도를 조사·분석한다. 또한, 연계전공 과목에 대한 학생들의 이해도 조사 및 교육효과성 분석을 통해 연계전공 진행에 대한 바람직한 방향을 제언한다. 이를 위해 연계전공 강의와 관리에 대한 설문을 실시하며 이를 이용하여 연계전공 과목과 진행에 대한 통계적 분석을 실시하여 문제점 진단 후, 향후 연계전공 진행방향을 제안한다.

The purpose of this article was to develop an interdisciplinary program for the aged living welfare in College of Home Economics. This program was developed through the analysis of gerontology curriculum in Korea, Japan, and America, and survey research with social workers who were working in the welfare institutes for the elderly in Korea. Moreover, an interdisciplinary program for the aged living welfare was designed based on the professional role of elderly care and the scope of educational context which were identified. Particular note was that this program could be most effectively implemented in the College of Home Economics. Recommendations for the development and implementation of the program were highlighted.

In this study, the object is a development on uroflowmetry system to detect a voiding symptom conveniently in home or hospital. The hardware was composed of mechanism and system circuit part, the software was divided into firmware and PC program part. The following experiment was performed to evaluate an ability of classification and fitness. First, the following parameters was calculated in each flow curve pattern. The parameters are MFR, AFR, VOL, VT, FT, and TMF. A significant difference among parameters was examined through a statistical analysis for extracted parameters between normal and abnormal group. In the next work, the following experimentation was performed to classify the voiding symptom. Analysis of congregate rate was examined to find out classification possibility about each symptom of BPH, voiding difficulty, detrusor failure and hyperreflexia, unstable bladder. The uroflow data with the above symptom was divided into normal and abnormal group using fuzzy classifier. and that was performed appending the other group again. Fuzzy classification result using MFR and AFR was superior by 89.6 % more than grouping evaluation including VOL.

Knowledge and better understanding of functions of the microbial community are pivotal for crop management. This study was conducted to study bacterial structures including Acidovorax species community structures and diversity from the watermelon cultivated soils in different regions of South Korea. In this study, soil samples were collected from watermelon cultivation areas from various places of South Korea and microbiome analysis was performed to analyze bacterial communities including Acidovorax species community. Next generation sequencing (NGS) was performed by extracting genomic DNA from 92 soil samples from 8 different provinces using a fast genomic DNA extraction kit. NGS data analysis results revealed that, total, 39,367 operational taxonomic unit (OTU), were obtained. NGS data results revealed that, most dominant phylum in all the soil samples was Proteobacteria (37.3%). In addition, most abundant genus was Acidobacterium (1.8%) in all the samples. In order to analyze species diversity among the collected soil samples, OTUs, community diversity, and Shannon index were measured. Shannon (9.297) and inverse Simpson (0.996) were found to have the highest diversity scores in the greenhouse soil sample of Gyeonggi-do province (GG4). Results from NGS sequencing suggest that, most of the soil samples consists of similar trend of bacterial community and diversity. Environmental factors play a key role in shaping the bacterial community and diversity. In order to address this statement, further correlation analysis between soil physical and chemical parameters with dominant bacterial community will be carried out to observe their interactions.
