본 논문에서는 DSRC(Dedicated Short Range Communication) 시스템을 이용하여 이동하는 차량에 탑재된 단말장치(OBE : On-Board Equipment)와 도로변에 설치된 기지국 장치(RSE : Road-Side Equipment) 사이에 5.8GHz대 ISM대역의 주파수를 사용한 무선패킷통신방식을 통한 차량위치 추적 시스템을 제안한다. 기존의 차량 위치 추적 방식은 차량위치를 파악하여 차량위치를 센터와 사용자에게 전송하는 무선 통신방식으로 단순한 센서만 사용되었지만, 본 시스템은 차량의 위치, 통관, 차량간 통신, 교통정보 수집 및 분배 등의 다양한 업무를 수행하도록 개발되었다. 또한, 빠른 처리를 위해 통신 계층 중 물리, 데이터링크, 응용계층으로 설계하여, 기존의 무선 통신방식 및 센서를 대처할 새로운 기술로 제안한다. In this paper, we propose an AVLS(Automatic Vehicle Location System) using the DSRC(Dedicated Short Range Communication) which adopts a radio communication tool between RSE(Road-Side Equipment) and OBE(On-Board Equipment) on a vehicle and uses the ISM bandwidth of 5.8GHz radio frequency. Typical AVLS uses the sensors for detecting the vehicle, but the DSRC system is developed for supporting various services such as the position of vehicle, clearance, vehicle to vehicle communication, collection and distributions of traffic and road information. Also, for fast processing, we design three-layer configuration of physical(L1), data link(L2), and application layer (L7), which simplifies the seven-layer configuration, We suggest the proposed system as a new technology for replacement of typical wireless communication system and sensors for AVLS.

洪承範,李錫淳 韓國作物學會 1995 Korean journal of crop science Vol.40 No.3

비파괴적으로 활력이 낮은 종자를 선별해내는 방법의 기초를 확립하고자 유채, 배추, 무 종자를 상대습도 90%, 온도 45℃ 에서 인위적으로 퇴화시켜 종자활력과 종자를 물에 침지 할 때 분비되는 당의 종류, 분비량, 분비시간과의 관계를 구명한 결과를 요약하면 다음과 같다. 1. 모든 작물의 건전종자는 전당을 분비하지 않았지만 죽은 종자는 침지 후 4~8시간부터 전당을 많이 분비하였다. 2. 유채, 배추, 무의 건전종자는 sucrose와 g1ucose를 가장 많이 함유하였고, stachyose, fructose, raffinose도 함유하였다. 인공퇴화과정에서 stachyose, raffinose, sucrose는 줄고, glucose와 fructose는 증가하였다. Experiments were conducted to know the relationships between seed quality and leakage of sugars from differently-aged seeds of rape, Chinese cabbage and radish. Seeds were artificially aged at 90% relative humidity and 45~circC to get different seed qualities. Significant amounts of total sugars were leaked from the dead seeds of all crops during the 8~24 hours soaking period, while high quality seeds leaked negligible amounts of total sugars. High quality seeds of all crops contained lots of sucrose and glucose and some stachyose, raffinose and fructose. During the artificial aging of seeds stachyose, raffinose, and sucrose decreased, while glucose and fructose increased

홍승범,권영혁,이만섭,허익,Hong, Seung-Bum,Kwon, Young-Hyuk,Lee, Man-Sup,Herr, Yeek 대한치주과학회 2002 Journal of Periodontal & Implant Science Vol.32 No.3

The purpose of this study is to evaluate histologically the resorption and tissue response of various resorbable collagen membranes used for guided tissue regeneration and guided bone regeneration, using a subcutaneous model on the dorsal surface of the rat. In this study, 10 Sprague-Dawley male rats (mean BW 150gm) were used and the commercially available materials included acellular dermal matrix allograft, porcine collagen membrane, freeze-dried bovine dura mater. Animals were sacrificed at 2,6 and 8 weeks after implantation of various resorbable collagen membranes. Specimens were prepared with Hematoxylin-Eosin stain for light microscopic evaluation. The results of this study were as follows: 1. Resorption : Inner portion of porcine collagen membrane was resorbed a lot at 6 weeks, but its function was being kept for infiltration of another tissues were not observed. Freeze-dried bovine dura mater and acellular dermal allograft were rarely resorbed and kept their structure of outer portion for 8 weeks. 2. Inflammatory reactions : Inflammatory reaction was so mild and foreign body reaction didn't happen in all of resorbable collagen membranes, which showed their biocompatibility. 3. In all of resorbable collagen membranes, multinuclcated giant cells by foreign body reactions were not observed. Barrier membranes have to maintain their function for 4-6 weeks in guided tissue regeneration and at least 8 weeks in guided bone regeneration. According to present study, we can find all of the resorbable collagen membranes kept their function and structure for 8 weeks and were rarely resorbed. Foreign body reaction didn't happen and inflammatory reaction was so mild histologically. Therefore, all of collagen membranes used in this experiment were considered proper resorbable membranes for guided tissue regeneration and guided bone regeneration.

홍승범,김대호,Mina Lee,Seong-Yeol Baek,Soon-Wo Kwon,Robert A. Samson 한국미생물학회 2011 The journal of microbiology Vol.49 No.4

Eurotium strains were isolated from 77 loaves of meju (dried fermented soybeans), in various regions of Korea from 2008 to 2010. Morphological characteristics and DNA sequences of β-tubulin were examined. They were identified as Eurotium amstelodami, E. chevalieri, E. herbariorum, E. repens, E. rubrum, and E. tonophilum. Of these species, E. chevalieri and E. tonophilum had not been previously reported in association with meju. E. chevalieri and E. repens were the species isolated most frequently. This paper summarizes the morphological characteristics of six Eurotium species and provides key to identify the species from meju.

홍승범,김대호,김선화,방나래,권순우 한국균학회 2013 韓國菌學會誌 Vol.41 No.2

Black Aspergillus is important fungus for oriental fermentation industry. Black Aspergillus was frequently isolated from Korean traditional Meju, a fermented soybean starting material for soy sauce and soybean paste. Thirty three strains were isolated from 98 finished Meju collected in various regions of Korea from 2008 to 2011, and 21 strains were isolated from in-process Meju at various farms from 2010 to 2011. The isolated black Aspergillus were identified using DNA sequences of partial β-tubulin and calmodulin genes. Of 54 black Aspergillus strains, 14 strains were identified as A. luchuensis and the others were composed of A. niger (n = 21), A. tubingensis (n = 10), and A. welwitschiae (n = 9).

Y-chromosome Haplogroup O3-M122 Variation in East Asia and Its Implications for the Peopling of Korea

홍승범,진한준,곽경돈,김욱 한국유전학회 2006 Genes & Genomics Vol.28 No.1

The analysis of Y-chromosome variation has become a useful tool for studies of the prehistoric migration route(s) and population expansions in human populations. A total of twelve Y-chromosome binary markers (D-YAP, C-RPS4Y711, M9, M214, M175, M119, P31, M95, SRY+465, DXYS5Y, M122, and LINE1) in 709 males from 11 ethnic groups was used to examine the distribution of the east Asian paternal lineages, and to evaluate the relative contribution of haplogroup O3-M122 lineages for the peopling of Korea. Our result is consistent with previous reports that the major Y-chromosomal expansions in east Asia were those of haplogroup O-M175 and its sublineages. Especially, haplogroup O3-M122 (a sublineage of haplogroup O-M175) appeared to be widespread and common in China and its surrounding regions. These results suggest that the haplogroup O3-M122 lineage may have originated mainland east Asia (probably southern China) and been extended into the surrounding populations. Thus, the earliest evidence of the ancient origins of east Asian agriculture and population studies imply that the preponderance of O3-M122, O2-P31, and their sublineages in Korea might be due to the influence of demographic process related to the early massive spreads of mainly male-mediated agriculture into the region.

가시광통신을 이용한 선박 내 위치 기반 응급호출 시스템

홍승범,이규호,Hong, Seung-Beom,Lee, Kyou-Ho 한국정보통신학회 2015 한국정보통신학회논문지 Vol.19 No.12

일반적인 선박 내 통신은 재질의 특성상 기존 RF기반 무선통신 기술을 적용하는 데 제약이 따른다. 가시광통신 기술은 가시광을 통신수단으로 하기 때문에 전파제약이나 간섭 같은 기존 무선통신 기술의 문제점을 해결할 수 있으며, LED조명을 활용한 통신과의 융합으로 추가적인 설비 요구가 상대적으로 낮고, 가시광을 이용함에 따라 인체에도 무해하다는 장점이 있다. 본 논문에서는 256Kbps급, 5m 전송 거리 급의 가시광통신 기술을 선박 내 통신에 적용함으로써 일반적인 RF통신기기 적용이 어려운 여건에서의 응급호출 시스템 솔루션을 제안하고, 제안 시스템의 실제구현과 시험을 통하여 그 타당성을 검증한 결과를 제시하였다. Due to metallicity of materials, a vessel has a limitation to adopt RF-based wireless communication technologies for the inner communication means. Visible Light Communication(VLC) can be a sound alternative to dissolve such a limitation. Using a visual light as a transmission medium, VLC is free from radio interferences and restriction of radio usages which are typically related to RF-based wireless communications. In addition, VLC can not only require the facility cost relatively low because of being possibly converged with existing LED illumination, but also be harmless to the human body. This paper proposes an indoor location-based emergency call service system solution for ships using the VLC technology that supports 256Kbps data rate and 5m transmission distance. This paper presents real implementation and testing results of the solution which verifies the propriety of the proposal.
