  • Feeding preference of cigarette beetle, Lasioderma sewicorne F., on cured tobacco leaves was investigated to obtain basic information on ecological management of the insect pest in tobacco storage warehouses. About 3, 000-4, 000 adults of the insect were released in a warehouse in which groud tobacco leaves were placed on the bottom and at 3m above the floor level, and numbers of insects attracted were examined. There was no significant difference on feeding preference between the two tobacco varieties, flue-cured(NC82) and air-cured(Br3l) tobacco leaves. However, significant differences were noted in feeding preference between thick and thin leaves and among different quality grades within a tobacco variety. Feeding preferences of cigarette beetle between flue- and air- cured tobacco varieties showed significant differences on the lower position, though there were no differences on the 3m upper position. On the 3m upper position, feeding preferences were different between thick and thin leaves of tobacco varieties, and variety X thickness and variety X thickness equality grades showed statistically significant differences. Significantly higher feeding preference by cigarette beetle adults was observed for the food placed on the 3m upper than on the lower position. There were negative correlations between quality grades of cured tobacco leaves and feeding preference on the lower position, and the regression equation was Y(feeding preference)=4.050-0.683 X (degree).

  • Purpose. To examine the effects of body position and time after feeding on gastric residuals in low birth weight infants(LBW). Methods. A repeated measures design was conducted. Twenty LBW infants being fed via indwelling nasogastric tubes were randomly assigned to one of 5 different position orderings. In each position, gastric residuals were measured at 30, 60, 90, 120, 150, and 180 minutes after feeding. Results. In comparisons of gastric residuals with position and time, the main effects of position and time were statistically significant (F=5.038, p=0.001; F=429.763, p < 0.001, respectively), but the interaction between position and time was found not to be significant. In pairwise comparisons, the gastric residuals were more reduced in the right anterior oblique and prone positions compared with the left lateral position (p < 0.05) and the differences across time periods were significant (p < 0.001). Conclusions. The body position after feeding has a significant affect on gastric residuals over time in LBW infants. The right anterior oblique or prone position is recommended rather than left lateral position after feeding. Knowledge of the proper position and the pattern of gastric emptying over time after feeding may lead to the development of evidence-based nursing care.

  • This paper analyze scenario of feeder wire fault that occurs in the AC feeding system considering train position. The fault location of AC feeding system is calculated by measuring impedance. However, in this way, estimation error can be occurred because of tie connection, boosting current, etc. Therefore, it's hard to find fault location, so that it is required to detailed circuit analysis according to fault location. We analyze the short circuit impedance values with respect to feeder wire fault according to a train position. In this paper, PSCAD is used for modeling and analysis of AC railway feeding system.

  • This research was conducted to survey the feeding methods of Korean women. The survey was executed for 355 mothers bringing up a child below 24 months in some part of Seoul in Korea from April to May, 1990. Incidence of breast feeding was 29.1% of the interviewed mothers in Seoul, which showed lower percentages than those of previous surveys. This research proved the major influencing factor generally depended on its mother rather than babies or labor condition. For example, the higher income and the higher educational degree of its mothers, they tended to prefer the bottle feeding to the others. Generally mothers knew the informations of infant nutrition very well, 84.5% of the interviewed mothers in Seoul had the opinion of 'breast feeding is better', but their knowledge actually didn't work. The source of mothers‘ informations on the infant nutrition showed the books and magazines, friend and relatives, grandmother were many by the order. But there were some discrepancies between the actual and needed source of information; i.e. mothers in Seoul mostly(44.8%) wanted to acquire their informations from mass communications. The reason of breast feeding showed 'for baby's health' was the greatest, and then 'immunity of breast milk' and 'baby's emotion' were great by the order, and the reason of bottle feeding showed 'not enough breast milk' was the greatest. There were no problems in feeding attitude and position of breast feeding, but there were problems in feeding volume, consistency of formula milk and feeding position of bottle feeding.

  • Purpose: Although Bednar's aphthae are common and regress spontaneously, these lesions may lead to feeding intolerance and are often misdiagnosed, rendering examinations useless. This study sheds new light on the clinical features of Bednar's aphthae. Methods: Sixteen neonates and infants were newly diagnosed with Bednar's aphthae via routine health check-ups in an outpatient clinic. Medical records were retrospectively reviewed, and the following parameters were analyzed; sex, gestational age, birth weight, mode of delivery, and perinatal problems. A physical examination was carried out during the next outpatient visit to examine the healing process and check for the existence of scars or complications. Results: Initial presentation included changes in feeding habits (n=10), longer feeding time, reduced intake, and increased irritability. In 6 patients, Bednar's aphthae were discovered incidentally, without prior symptoms. Feeding posture and method of feeding are important causes of Bednar's aphthae. Eleven patients were fed in a horizontal position, whereas 5 patients were fed in a semiseated position. Fifteen patients were bottle-fed, whereas 1 patient was exclusively breastfed. After correcting the feeding position, the ulcerative lesions disappeared within 1 month of diagnosis. During the follow-up period, lesions did not recur in any of the patients. Conclusion: This study suggests that Bednar's aphthae are caused by mechanical pressure. A diagnosis of Bednar's aphthae should be considered when lesions are found on the palate of infants and when symptoms seem to be feeding related. Proper education of parents can both treat Bednar's aphthae and easily prevent its recurrence.

  • This study was to investigate the relationship between hospital nurses 'knowledge of breast-feeding and their ability to provide care to breast-feeding mothers and their children. From Nov. 1 to 30, 1999, 105 nurses of the obstetric ward, delivery room, OPDs of obstetrics and gynecology, and nurseries of three general hospitals from Seoul and Pusan were evaluated. The results are as follows: 1.Mean score of nurse's knowledge to breast-feeding was 12.76. Mean score of performance of nursing activities was 109.80. 2.General characteristics and feeding characteristics were significantly related to nurse's knowledge to breast-feeding and performance of nursing activities related to breast-feeding. Nurse's knowledge about breast-feeding was significantly related to age, working ward, clinical experience, rank of position, experience of breast-feeding and experience education on breast-feeding. Performance of nursing activities for breast- feeding was significantly related to age, working ward, experience in other ward, marital status, and education on breast-feeding. 3.A positive correlation between nurse's know-ledge to breast-feeding and performance of nursing activities related to breast-feeding was statistically significant(r=.381, P<0.05).

  • This paper is concerned on kinematic analysis and simulation of an automatic feeding mechanism subjected by the motion of a curvilinear inverse can. The curvilinear cam is rotated by positioning a translating roller and the automatic feeding mechanism is moved to the sliding position by the motion of a campin fixed on the curvilinear cam. The curvilinear cam consists of two arcs of circles and two straight lines. The modular approach is used for the kinematic analysis of the feeding mechanism. As the first part of the paper for the motion simulation of the cam-feeding system, this paper discusses the algorithm to simulate the motion of the cam-feeding mechanism. The second part of the paper presents the state-of-art for the graphics-oriented CAD technique,

  • This study proposes a methodology with which the optimal damper positions of the feeding system in a CD-ROM drive are determined to removal the harmful tilting vibration modes. For this purpose, vibration characteristics of the feeding system are identified by a theoretical modeling as well as vibration experiments. We perform the modal testings using the impact hammer and shaker; furthermore, we establish a vibration model due to the rigid-body motion. The analysis and experiments show that the feeding system has three rigid-body vibration modes in the low-frequency region and two of them come from the tilting modes. We show that the tilting modes can be removed by determining the damper positions.

  • Recent developments of Laser metal 3D deposition with wire feeding are reviewed which provide an alternative to powder feeding method. The wire feeding direction, angle and position as well as laser power, wire feeding rate, and deposition speed are found to be key parameters to make quality deposition with high throughput. When compared with the powder feed, the wire feed shows higher material efficiency, higher deposition rate, and smoother surface. Large elongated columnar grains which have epitaxial growth across deposit layers are observed in deposit cross sections. The growth direction is parallel to the thermal gradient during the deposit process. Tensile properties are found to be dependent on the direction due to the anisotropic deposit property. A real-time feedback control is demonstrated to be effective to improve the deposition stability.
