To find risk factors of hypertension among farmers whose age were 30 or more living at a rural area in the suburbs of Kwangju, a case-control study was done toward hypertensive patients and age-sex matched controls. Case groups were composed of mild hypertensive group of 70 patients whose blood pressure were 140/90 mmHg or more and below 160/100mmHg, and moderate hypertensive group of 54 patients whose blood pressure were 160/100mmHg or more. As control groups same number of persons were chosen from normotensive patients by age and sex frequency matching. The results are as follows : 1. No significant differences of educational level, marriage state, occupation and monthly Living expenses were found between case and control groups. 2. Among the mild hypertensive group the odds ratio for drinking more than 50 gm of alcohol daily versus non-drinker was 5.06 (95% confidence interval 〔CJ〕1.39 - 18.38): odds ratio for persons with high score to take salty food versus persons with low score to take salty food was 2.45 (95% CI 1.23-4.88): odds ratio for persons who were at sitting position for more than :t. 5 hours a day versus persons who were at sitting position for less than 4.5 hours a day was 2.26 (95% CI 1.15-4.47) respectively. 3. Among the moderate hypertensive group a trend was found to increase the odds ratios for drinking alcohol 20- 39.9 gm versus non-drinker, high body mass index (BMI) versus low BMI, high waist-hip ratio (WHR) versus low WHR, persons who took more fatty food versus persons who took less fatty food, and for persons who slept less than 7 hours or more than 9 hours a day versus persons who slept for 7 - 9 hours a day. The odds ratios for persons who worked for more than 10 hours a day versus persons who worked for less than 10 hours a day showed 0.59. But the confidence interval values were not statistical1y significant. In conclusion excess drinking. high salt intake and inadequate activity were found to be the significant risk factor for mild hypertension of the farmers. So appropriate education to change the life stile are necessary.

Background: Phototrichogram analysis of normal scalp hair characteristics in Asian populations is not well characterized. Objectives: To investigate the normal hair characteristics of South Koreans using a phototrichogram. Methods: We enrolled 674 males and 683 females between the ages of 10 and 69. Hair density, thickness and the white hair percentage were measured via phototrichogram. Six scalp sites, including front, top, the peak between top and back, back, and the right and left sides were targeted. Results: The mean hair density, hair thickness, and the white hair percentage were not significantly different between genders at any scalp site. The mean hair density and thickness were significantly different according to scalp sites. Hair density declined with age, especially at the peak between top and back. Males and females showed different patterns of aging in hair density. Hair thickness changed little with age. But, mean hair thickness generally tended to increase until the 20s, reach a plateau between the 20s and 50s, and decrease after the 50s. The mean white hair percentages were 1.84 ± 4.24% in males and 1.66 ± 4.21% in females. The mean white hair percentages were significantly increased in subjects greater than 40 years of age. Conclusion: We described the normal characteristics and aging patterns of scalp hair in a Korean population.

Endotoxin crystals produced by B.thuringiensis var. darmstadiensis cultured in modified GYS medium over 72 h were ovoidal in shape and separated using Renografin gradient centrifugation. The crystal protein bands were observed. When B.thuringiensis var sotto was grown in the modified GYS broth, it entered stationary phase at 8-9 h after inoculation. Proteinaceous crystals were banded at the position in 40% of Renografin gradient. The solubilized crystal proteins were formed by two bands, 130 Kd and 68 Kd in the SDS-PAGE. One plasmid was observed in B.thuringiensis var darmstadiensis and no plasmid in var. sotto in this study. Enzyme activity of amylase produced B.thuringiensis var kurstaki strain in the basal medium was 0.4 units per ml, and was enhanced to 0.6 units per ml in the basal medium contained soluble starch, Ca^++, Mg^++ and Mn^++ ions. Amylase production medium containing soluble starch was suitable for the amylase production and the highest activity appeared at 4-6 h after cultivation at 32℃. The amylase activity obtained by ethanol precipitation was 0.20 units per ml in 0.1 M phosphate buffer. The band of the molecular weight of 50 Kd was observed by SDS-PAGE analysis. Km value of the amylase for the soluble starch was 6.80 mg per ml.

노광현(Ro, Kwang-Hyun),김상현(Kim, Sang-Hyun) 한국산학기술학회 2012 한국산학기술학회논문지 Vol.13 No.5

본 연구에서는 외부 장착물이 존재하는 항공기의 안정성 검증을 위해 진동 및 구조해석을 수행하였다. 외부 장착물이 존재하는 경우, 외부 장착물 자체의 정확성 및 안정성을 위한 요구조건이 주어지며, 이와 동시에 외부 장착 물이 항공기에 장착되도록 개조된 항공기 구조물의 안정성 문제가 중요하다. 따라서 본 연구에서는 정적 상태에서의 고유주파수 계산을 통한 공진 여부를 조사하고 발사기를 장착하기 위해 개조된 구조물에 작용하는 진동하중을 구하 였다. 또한 로컬 모델링 방법을 이용하여 추가 장착 구조물의 구조적 안정성을 검토하였으며 지상 및 비행시험을 통 하여 이를 검증하였다. This paper presents the stability analysis of UH-60 helicopter with external store such like chaff/flare dispenser. An external store can affect the natural frequency of the aircraft and induce the resonance, which cause the failure of structures. In this paper, therefore, Rayleigh method is used to investigate the resonance with aircraft and external store, and transmission formula is used to determine the vibration load. Structural analysis with local modeling method are performed to present the robust design of aircraft with external store. The ground and flight test are also done to verify the stability of the aircraft.

Chitin is exists in the exoskeleton of crustaceans and chitosan can be obtained by deacetylation of chitin. As chitosan has a chelating characteristics, it was used radiostrontium chelator in the rats and mice. It also can be used as a healthy food and medicine. The purpose of the prsent study is to investigate the chitosan distribution and excretory route of 14C-chitosan in the animal body. 14C-chitosan was prepared and intravenously administered to the vein of mice and also intraorally ingested. The body distribution of chitosan was studied by autoradiography and the urinary excretion was counted. C-14 label chitosan was showed high distribution in the liver. And 10~20% of chitosan was excreted to the urine through kidney within few days. Chitosan was gathered into gromerulus in kidney and excreted from three hours. It was concluded that chitosan has no target organs and liver distribution is a sort of only passing route for the urinary excretion by way of kidney.

본 연구에서는 범용 이동정보통신기기인 스마트폰을 플랫폼으로 하는 차선이탈경보 애플리케이션을 개발하 고 최적화하였다. 최근 안전주행지원 솔루션 중 하나인 차선이탈경보시스템이 상용화되고 있지만, 고성능의 전용 플 랫폼을 필요로 하기 때문에 시장에 쉽게 진입하지 못하고 있다. 본 연구에서는 스마트폰인 iPhone 3GS를 플랫폼으로 하는 차선이탈경보 애플리케이션으로 개발하고 처리 속도를 최적화하였다. 효율적인 영상처리를 위해서 OpenCV를 사용하였고, 차선인식을 위해서는 차선의 기하학적 특징을 고려한 Hough Transform 기반의 휴리스틱 알고리즘이 고 안되었다. 차선이탈경보 애플리케이션은 매킨토시 컴퓨터에서 Xcode 3.2.4 개발툴을 사용하여 개발되었고, 스마트폰에 다운로드하여 실제 도로에서 실험하였다. 실험결과 1.52fps의 처리 속도를 보였고, 최적화 작업을 통해 처리 속도를 3.84fps까지 향상시켰다. 향후 차선인식 알고리즘 보완, 추가 최적화 작업 및 고성능 스마트폰 플랫폼 채택 등을 통해 스마트폰용 차선이탈경보 애플리케이션을 상용화할 계획이다. The purpose of this research is to develop and optimize a lane departure warning application based on a smartphone which can be applicable as a new platform for various mobile information applications. Recently, a lane detection warning system which is a representative application among safe driving assistant solutions is being commercialized. Due to the necessity of powerful embedded hardware platform and its price, its market is still not growing. In this research, it is proposed to develop and optimize a lane departure warning application on iPhone 3GS. OpenCV is used for efficient image processing, and for lane detection a heuristic algorithm based on Hough Transform is proposed. The application was developed under Macintosh PC platform with Xcode 3.2.4 development tools, downloaded to the iPhone and has been tested on the real paved road. The experimental result has shown that the detection ratio of the straight lane was over 90% and the processing speed was 1.52fps. For the enhancement of the speed, a few optimization methods were introduced and the fastest speed was 3.84fps. Through the improvement of lane detection algorithm, additional optimization works and the adoption of a new powerful platform, it will be successfully commercialized on smartphone application market.
