  • In this paper, we implemented this failure detecting and monitoring system for high-pressure natrium lamps and ballasts. The hall CTs of the local detecting system measure the current flowing into natrium lamps via ballasts and acertain whether the natrium lamps or ballasts are out of order or not. These test data are transmitted to the main monitoring system. So, we can see the status of the natrium lamps or ballasts promptly.

  • This study was carried out to investigate the effects of the wound contraction of chitosan, aloe vera, fucidin natrium, and premycin ointment on defected wound from full-thickness skin defects(1 cm $\times$ 1 cm). Twelve dogs were designed in 5 different positions on the dorsal thoracolumbar. We examined the effects of wound contraction every four other day 16 for days. Percentage of wound contraction based on epitherial overall area of defected wound which calculated by image analyzer and computer. Four to 8 days after wound contraction in wound defected dogs, the epithelial overall rate were the most high presented by 48.1 % in the chitosan group and were the lowest by 26.8% in the premycin group. In 16 days, chitosan group were the most heigh presented by 94.4% and premycin group were the lowest by 76.5% compare to saline group of 85.9%. Thus, we conclude that the chitosan is a possible role for improvement of wound contraction by wound defected dogs.

  • This study was carried out to reduce children's sugar, natrium and fat intakes and establish their healthy lifestyle. To achieve these goals, we developed an educational web site and an e-learning system. The targets of this web site are children, parents and educators. This site has various information about sugar, natrium and fat, and has special menus for each target: such as the 'Let's study' for children, 'Guides for child's eating' for parents, and 'Educational softwares, Lesson plans/materials, and Textbooks/Teaching guides' for educators. We developed three nutrient characters and applied them to the web site. We provided information in the form of texts, images, flash and sounds. This site has special boards in 'Nutrition cafe' menu to interchange information or their successful stories between the connecters. We developed an e-learning system with two courses. One is for junior elementary students and the other is for senior students. Children can study each nutrient step by step in a course according to their academic ability and concern. Also, they can evaluate their academic achievement in this system, which was uploaded into 'Let's study' in children menu in the web site. Conclusively this web site and e-learning system could contribute to reducing children's sugar, natrium and fat intakes by helping children study them systematically and effectively by on-line system. We expect this e-learning system would be a new nutrition education system to make nutrition education more active.

  • 고압방전등을 점등하기 위해서는 고전압의 시동전압이 필요하게 되는데, 이러한 시동전압은 고 압력의 나트륨램프에서도 필요하게 된다. 자기장은 전기 방전튜브에서 만들어지게 되며 증기 원자에 대한 전자충돌이 가속화되면서 2차 전자가 발생하고 전기 방전튜브에 전류가 급속도로 흐르게 되며, 나트륨램프의 제자회사마다 서로 다른 램프의 수명 및 교환시점도 서로 다르게 다는 것을 본 논문의 연구과정에서 발견하게 되었다. 본 논문에서는 LabVIEW 소프트웨어패키지를 사용해서 발견한 내용을 나트륨램프의 수명진단의 알고리즘을 제안한다.

  • Cordyceps has been used as a tonic for replenishing vital function in Chinese traditional medicines. As an attempt to obtain fundamental data for the kidney function, MeOH Ex. and its hexane. ethyl acetate, butanol and water fractions of cultivated Cordyceps pruinosa on mercuric chloride induced renal failure rats were investigated. Urin volume. blood parameters(urea nitrogen. uric acid. creatinine) and urinary electrolytes content (natrium. potassium. chloride) were determined. MeOH extract and butanol fraction showed diuretic effect. (omitted)

  • Polygonum cuspidatum has been used as treatments of dermatitis, inflammation, hyperlipidemia and diuretics in folk remedies. In order to evaluate the urinary effect of Polygoni cuspidati Radix, its MeOH extract was administerd in rats. We determined the total urin volume, chemical parameters(urea nitrogen, creatinine, uric acid), electrolytes(natrium, potassium, chloride) ) in serum and urin. Polygoni cuspidati Radix showed increase in urin volume and electrolytes.

  • Flow-injection analysis (FIA) for on-line monitoring of glucose and acetate are described and employed in E.coli fermentation process. Glucose oxidase (GOD) for the detection of glucose is immobilized on epoxy polymer support, which is packed in a small cartirdge, and applied to a GOD-FIA system. The detection of acetate is based on the inhibition of acetate to the oxidation of sarcosine by sarcosine oxidase (SOD). SOD is also immobilized on epoxy polymer support and used for a SOD-FIA system. GOD-FIA system is characterized as well as SOD-FIA system by the investigation of the effects of pH, temperature and metabolites in samples on the peak height. GOD-FIA and SOD-FIA systems were also applied for on-line On-line measurements buy FIA measurements by FIA were in god agreement with off-line measurements.

  • Sodium silicate - the usual portland cement which accomplishes a cement pouring reconsideration main stream and sodium silicate(No.3) after reacting sodium silicate(No.3) with the reaction sodium silicate where oxidation natrium which is included does not react with the cement receiving stiffening water it will burn together on underwater and to become the durability lacks pouring it is recognized. From the hazard which improves an advantage it used the additive which relates in congealing and stiffening of the portland cement and sodium tripolyphosphate(STPP) addition hour initial material age(72 hours at once) which does to be revealed the at high-in-tensity is discovered while accomplishing. The effect of additives on the reactions of sodium silicate solution and cement suspesion was investigated by various physical and chemical tests, such as Si-NMR, XRD, SEM uniaxial compression test. The additives were STPP(sodium tripolyphosphate), EDTA, SUGAR. The compressive strength of sodium silicate(No.3) - cement grout with additives was about $1.5{\sim}10$ times higher than that without additive in early age(72 hours).

  • This study was done to investigate and compare the nutritional status and plasma lipids in the diabetes and control elderly. Subjects were 105 persons (male 32, female 73) aged over 65 years and visited public health centers in Ulsan area. The subjects were divided into 2 groups, diabetes and control group. Athropometric measurement, dietary intakes, and plasma biochemical indices were examined. Body Mass Index (BMI), Percentage of Ideal Body Weight (PIBW) and Waist-Hip Ratio (WHR) of diabetes group were higher than those of control group. Overall eating behavior were worse in diabetes group than those of control group. There was no significant difference in smoking and exercise status among groups. The ratio of drinkers was significantly higher in control group. But the amount of alcohol consumed at once was higher in the diabetes group. There was no significant difference in most nutrient intakes between males and females. The intakes of fiber, natrium (Na), vitamin A, and $\beta$-carotene were significantly higher in diabetes group than control groups while that of potassium (K) was lower in diabetes group. Diabetes group had the higher levels in triglyceride, VLDL-cholesterol, Chol/HDL-cholesterol ratio, LDL/HDL-cholesterol ratio, while they had lower HDL-cholesterol level. Overall results might imply that the elderly with diabetes have to be more careful to their meals and health-related behaviors to increase the likelihood of a healthier life.
