교량감시를 위한 무선 센서 네트워크 구조 및 보안 프로토콜
임화정,전진순,이헌길,Lim Hwa-Jung,Jeon Jin-Soon,Lee Heon-Guil 한국컴퓨터산업학회 2005 컴퓨터産業敎育學會論文誌 Vol.6 No.3
The wireless sensor network consists of a number of sensor nodes which have physical constraints. Each sensor node senses surrounding environments and sends the sensed information to Sink. In order to alleviate the inherent vulnerability in security of the wireless sensor nodes with the hardware constraints, the lightweight security protocol is needed and a variety of research is ongoing. In this paper, we propose a non-hierarchical sensor network and a security protocol that is suitable for monitoring man-made objects such as bridges. This paper, furthermore, explores a two-layer authentication, key distribution scheme which distributes the key and location of a sensor node in advance, and an effective security routing protocol which can take advantage of the Sleep and Awake state. This also results in the increased data transfer rate by increasing the number of alternative routing paths and the reduced energy consumption rate. 무선 센서 네트워크는 물리적인 제약을 가진 수많은 센서 노드들로 구성되어 있다. 각 센서 노드는 주변의 상태를 감지하고, 감지된 정보를 싱크(Sink)로 보내는 역할을 한다. <중략> 본 논문에서는 교량과 같은 인공구조물에 적합한 비 계층적 무선 센서 네트워크 구조를 제시하였다. 또한, 센서 노드들의 휴면(Sleep)과 활동(Awake) 상태를 이용한 효율적인 보안 라우팅 프로토콜과 센서 노드의 키와 위치 정보를 사전에 노드에 분배하는 사전 키 분배 방식 및 2계층 인증 기법을 제안하였다. 제안하는 방식은 대체 경로 수의 증가로 인한 데이터 전송률의 증가와 에너지 소모율의 감소 효과를 보였다.

항암항생제 Rhodomycin의 Aglyconed인 (±)-γ-Rhodomycinone과 10-Deoxy-γ-rhodomycinone의 합성(제2보)
趙仁鎬,전진순,魯永釗,Rhee, Richard P 全北大學校 基礎科學硏究所 1991 基礎科學 Vol.14 No.1
항암항생제 Rhodomycin(2)의 합성단계 최종물질인 (±)-γ-Rhodomycinone(4)과 10-Deoxy-γ-rhodomycinone(5)이 9-ethyl-9,10-epoxy-4,6,11-trihydroxy-7,8,9,10-tetrahydronaphthacene-5,12-dione(10)의 epoxide ring 쪼개짐으로부터 만들어졌고, epoxide 10은 Hauser-Rhee가 개발한 고리접합법을 이용해서 만든 9-acetyl-4,5,6,11,12-pentamethoxy-7,8-dihydronaphthacene(6)으로 부터 얻었다. (±)-γ-Rhodomycinone(4) and 10-Deoxy-γ-rhodomycinone(5), late-stage Precursors of the alglycone of antitumor antibiotic Rhodomycin(2) were prepared from the cleavage of epoxide ring of 9-ethyl-9,10-epoxy-4,6,11-trihydroxy-7,8,9,10-tetrahydronaphthacene-5,12-dione(10). The epoxide 10 was furnished from 9-acetyl-4,5,6,11,12-pentamethoxy-7,8-dihydronaphthacene(6), which was assembled utilizing ring annelation methodology developed by Hauser-Rhee.

The wireless sensor network consists of a number of sensor nodes which have physical constraints. Each sensor node senses surrounding environments and sends the sensed information to Sink. The inherent vulnerability in security of the sensor nodes has promoted the needs for the light weight security protocol. In this paper, we propose a non-hierarchical sensor network and a security protocol that is suitable for monitoring the man-made objects such as bridges. Furthermore, we present the efficient way of setting the routing path by storing IDs, MAC(message authentication code) and the location information of the nodes, and taking advantage of the two node states, Sleep and Awake. This also will result in the reduced energy consuming rate.

센서 네트워크는 많은 수의 센서 노드들로 구성된 네트워크로 센서를 통해 주변 정보를 감지하고 감지된 정보를 수집하고 처리한다. 센서 네트워크는 그 적용 분야가 광범위하여, 그에 따른 보안요구사항 또한 다양하다. 교량 감시에 사용되는 센서들의 특징은 교량에 일정한 간격으로 고정되어 위치하여 센서이동이 거의 없는 고정된 센서 네트워크를 형성하게 된다. 따라서, 이러한 특징을 고려한 보안프로토콜의 개발이 필요하다. 본 논문에서는 교량 감시에 사용되는 센서 네트워크와 같이 고정된 센서들로 이루어진 네트워크상에서의 보안 요구사항을 분석하고 이를 만족시킬 수 있는 보안 프로토콜을 제시한다.

여자 중,고등학생의 식품영양표시제 이용과 영양표시 이해도 및 식행동 조사
정은정 ( Eun Jung Chung ),전진순 ( Jin Soon Jeon ),안홍석 ( Hong Seok Ahn ) 대한영양사협회 2010 대한영양사협회 학술지 Vol.16 No.3
This study investigated the use and understanding of food and nutrition labels in 498 female adolescents (middle school students: MS 248, high school students: HS 250) in Gyeonggi-do. Fifty percent of the MS and 47.2% of the HS read food labels, and the most common reasons for reading labels were to find a product`s expiration date and price. The food label information considered most important by the subjects was the name of the manufacturing company and expiration date. Over 80% of the subjects read nutrition labels. The MS read nutrition labels to find nutrients and their amounts in foods, while the HS read labels mostly in an effort to control body weight. These subjects gave more attention to calories and fat, the nutrients related to body weight, than to other nutrients. The subjects were highly aware of the necessity and positive effects of nutrition labels, because they believed labels could make it easier for them to choose healthy foods. However, scores for understanding nutrition labels showed the subjects failed to understand label information accurately. Generally, the MS showed better dietary behaviors than HS. But the HS had significantly higher scores than MS for the item "know relative weight with height." Those that read food labels had significantly better BMIs, dietary behaviors, and awareness and understanding of nutrition labels. There were significant positive relationships among awareness & understanding of nutrition labels and subjects` dietary behaviors. The study findings can be utilized to better plan nutrition education programs aiming to improve use and awareness of food and nutrition labels among adolescents.

To investigate the effects of ethanol on the lipid metabolism in blood and liver, twenty one male Sprague Dawley rats had orally taken the 25% alcohol and 50% alcohol by 5g per Kg of weight during 3 weeks after the adjusting period. For the energy balance, 85% sucrose and 45% sucrose was added in control group and 25% alcohol group each. The weight was reduced by alcohol treatment according to the levels, otherwise the weight of liver and heart was little increased in alcohol groups rather than in control without significance. Moreover, RBC, WBC, hemoglobin and hematocrit were increased by alcohol treatment according to the levels without significance. Otherwise, adjusted bilirubin levels by 100g of weight was significantly increased by alcohol treatment dose dependently. Alcohol induced RBC degradation and increased circulated bilirubin because of liver damage. For blood lipid profiles, blood cholesterol was increased in 50% of alcohol group compared to that of 25% and control groups, otherwise, blood triglycerides (TG) was increased by 30% in 25% alcohol groups rather than in control but not significantly different. The hepatic lipid composition, cholesterol levels in alcohol treatment groups was lower than those in control. The hepatic TG was not influenced by alcohol treatment. The two reasons of decreasing hepatic lipids were suggested by 85% sucrose of control for energy balance more synthesized cholesterol and TG than those in 25 or 50% alcohol groups, and by cholesterol and TG could not be synthesized because of liver damage from alcohol.
