Purpose: The purpose of this study was to measure the effects of a breast feeding promotion program for working women on breast feeding continuation, mother-infant attachment, and maternal sensitivity. Methods: The design of this study is nonequivalent control group design with repeated measures. Results: There were significant differences in breast feeding continuation between two groups at each time point except 2 days and 1 week after delivery. The scores of mother-infant attachment and maternal sensitivity of experimental group were higher than those of the control group, but there were no significant differences between two groups. Conclusion: Although some modifications in contents and administration will be required to increase the effectiveness of the program, breast feeding promotion program for working women can be an effective nursing intervention which can facilitate breast feeding continuation and mother-infant relationships.

When ruminants consume dry forage, they also drink large volumes of water. The objective of this study was to clarify which factor produced when feed boluses enter the rumen is mainly responsible for the marked increase in water intake in the second hour of the 2 h feeding period in large-type goats fed on dry forage for 2 h twice daily. Six large-type male esophageal- and ruminal-fistulated goats (crossbred Japanese Saanen/Nubian, aged 2 to 6 years, weighing $85.1{\pm}4.89kg$) were used in two experiments. In experiment 1, the water deprivation (WD) control and the water availability (WA) treatment were conducted to compare changes in water intake during and after dry forage feeding. In experiment 2, a normal feeding conditions (NFC) control and a feed bolus removal (FBR) treatment were carried out to investigate whether decrease in circulating plasma volume or increase in plasma osmolality is mainly responsible for the marked increase in water intake in the second hour of the 2 h feeding period. The results of experiment 1 showed that in the WA treatment, small amounts of water were consumed during the first hour of feeding while the majority of water intake was observed during the second hour of the 2 h feeding period. Therefore, the amounts of water consumed in the second hour of the 2 h feeding period accounted for 82.8% of the total water intake. The results of experiment 2 indicated that in comparison with the NFC control, decrease in plasma volume in the FBR treatment, which was indicated by increase in hematocrit and plasma total protein concentrations, was higher (p<0.05) in the second hour of the 2 h feeding period. However, plasma osmolality in the FBR treatment was lower (p<0.05) than compared to the NFC control from 30 min after the start of feeding. Therefore, thirst level in the FBR treatment was 82.7% less (p<0.01) compared with that in the NFC control upon conclusion of the 30 min drinking period. The results of the study indicate that the increased plasma osmolality in the second hour of the 2 h feeding period is the main physiological stimulating factor of water intake during and after dry forage feeding in large-type goats.

The purpose of this study is to investigate the effect of an educational program on parturient women's feeding behavior One hundred and twenty seven mothers who delivered in one general hospital in Seoul participated in the study, 66 mothers of whom were assigned to experimental group and 61, to control group. The data collection was done from April 20 to June 30 in 1997 and the educational program was applied to the experimental group on the third postpartum day and telephone calls were made on the fourth and the twelfth postpartum week to investigate feeding behavior after discharge. The collected data were analyzed by means of Chi-square test and descriptive statistics. The results are as follows : 1. Breast-feeding rate of the experimental group was higher than that of the control group($x^2$=6.578, p=.043). 2. Background variables affecting feeding behavior were age and feeding plan(age: $x^2$=8.660, p=.070, feeding plan : $x^2$=25.762, p=.000). 3. The insufficient milk supply was the main cause of discontinuing breast-feeding and others were mother's job, baby's jaundice and diarrhea, baby's refusal to suck breastmilk. In conclusion, the breast-feeding educational program which was applied in this study is effective in the promotion of breast-feeding.

The variations of both thiamine and riboflavin value in the organs, viz. liver, small intestine, spleen and kidney of the rats were measured for observing some metabolic changes in the animals during fasting and feeding different quality of diets without V-E supplement. The animal used for the experiment was adult female ablino rat from a pure strain, weighing 225-280g. The animals were divided into 6 groups; the control group, the high carbohydrate diet group, the high carbohydrate diet with V-E group, the high protein diet group, the high protein diet with V-E group, and fasting group. The result obtained are summarized as follows; 1. The thiamine contents in the liver were once increased during early stage of starvation compared with the control group, thereafter they were decreased on the 8 days fasting while the contents in the small intestine and spleen were decreased during 1 to 8 days fasting. 2. The riboflavin contents in the liver and kidney were increased during starvation and the content in the small intestine was no marked change compared with control group. 3. The thiamine contents in the liver and small intestine during feeding the high carbohydrate with V-E supplement diet group were lower than that of the diet without V-E group and the content in the spleen was increased by feeding V-E enriched high carbohydrate diet. 4. The thiamine contents in the liver, small intestine and spleen during feeding the V-E supplemented diets were lower than that of the non-supplemented one's. 5. The riboflavin contents in the liver, small intestine, and kidney were increased during feeding the high carbohydrate diet compared to the control group, and they were decreased during feeding the V-E enriched high carbohydrate diet. 6. The riboflavin contents in each organ were increased during feeding the high protein diet compared to the control group, and they were much increased during 20 to 30 days of feeding the V-E supplemented high protein diet. 7. Therefore, as the above results showed, the variation of thiamine value in the each organs were not markedly changed during feeding different quality of the diets. The thiamine and riboflavin contents in the each organ in the V-E enriched high carbohydrate diet group were lower than without V-E supplemented one's The riboflavin contents in each organ were increased during feeding the high protein diet compared with the control group and the centents were increased during 20 to 30 days of the feeding V-E enriched high protein diet.

This study was devised to observe the nutritional effect by feeding of rice diet supplemented with Ginseng powder in Albino rats. The male albino rats (84 heads), weghing about 56g, were used for the experimental animals. They were divided into six diet groups; which were the 6.4% protein diet, the 12.8% protein diet and the 17.9% protein diet as the control and each control diet was supplemented with 3% of Korean Ginseng powder as experimental diet. These diet groups were again divided into 2 groups according to the feeding terms, 3 weeks and 6 weeks. The animals were sacrificed after feeding the coresponding diet for 3 weeks and 6 weeks and the liver, heart, kidney, intestine and serum were collected as samples for analysis. The growth rate, efficiencies of protein and food, lipid, cholesterol and nitrogen in the samples were determined. The results obtained are summerized as follows; 1. The growth rate were improved by feeding of the 13% and the 18% protein diet supplemented with 3% ginseng powder than the coresponding control diet group, although the same results were not observed in the 6.8% protein diet groups. 2. The consumptions of the food and the protein in each dietary group were similar to each other. 3. The efficiencies of the food and the protein were improved by feeding of the 13% and the 18% protein diet supplemented with the ginseng powder than each control diet group. 4. The lipid contents in the liver of each expperimental diet group, in the feeding for 3 weeks, were shown the tendency to increase slightly, compared with the coresponding control group, whereas in the feeding group for 6 weeks, the contents were shown rater the decreasing tendency. 5. The total cholesterol contents in the liver of each experimental diet group, in the feeding group for 3 weeks, were maintained slightly higher level than the coresponding control group, whereas in the feeding group for 6 weeks, the contents were shown similar levels. 6. The total cholesterol contents in the heart were maintained with similar level in each diet group and each feeding term.

This paper presents vibration control of a CD-ROM(compact disc-read only memory) drive feeding system consisting of a new type of CD-ROM mount using an electro-rheologocal(ER) fluid. Chemically treated starch particles and silicon oil are used for EF fluid, and its field-dependent yield stresses are experimentally distilled under both the shear and the flow modes. On the basis of the yield stress, an appropriate size of ER CD-ROM mount adapted to conventional feeding system is designed and manufactured. Vibration isolation performance of the proposed mount is evaluated in the frequency domain and compared with that of conventional rubber mount. The ER CD-ROM mount is then installed to the drive feeding system and the system equation of motion is derived. The skyhook controller is then incorporated with the fuzzy technique to improve the performance of ER CD-ROM mount. A set of fuzzy parameters and control rules are obtained from a relation between vertical displacement and pitching motion of the feedng system. Followingthe formulation of the fuzzy-skyhook controller, computer simulation is undertaken in order to evaluate vibration suppression of the CD-ROM drive feeding system subjected to various excitations.

Significant low knowledge and poor attitudes on complementary feeding undermine the practices. This study was a cluster randomized controlled trial in which 284 study participants were assigned into two groups. One intervention group and a control group in a ratio of 1:1. Nutrition education on complementary feeding was carried out among the caregivers in the intervention group but the caregivers in the control group were not educated. To determine complementary feeding knowledge and attitudes, data was collected from caregiver at baseline, midline and at endline using researcher-administered questionnaires. Quantitative data were analyzed using SPSS version 22.0. From the analysis, there was a significant difference in complementary feeding knowledge of the caregivers after the intervention. The baseline difference was -0.06, the midline difference was 3.85 the endline difference was 4.00 and the DID of the baseline and endline was 4.06 which was significant at p=0.001. There was a significant difference in the attitude of the caregivers towards complementary feeding at baseline (-0.14), midline (2.09), endline (3.82) and the DID of baseline and endline was 3.96 which was significant at p=0.001. The intervention improved the caregivers' knowledge on complementary feeding and it improved the attitudes of the caregivers towards adequate complementary feeding.

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.

Liquid feeding of hogs can be controlled by using feed-level-sensors in the troughs. In this way restricted feeding with computer control of the eating time is possible. For this purpose the feed supplied is adjusted according to the eating time of the previously fed portion. With ad libitum feeding the same sensors can provide for a clean trough once a day and thus help to overcome sanitary problems. The effect of the feeding systems on daily intake and performance of hogs are dealt with.

In the recent years, development of machine tool with high speed feeding system have brought a rapid increase in productivity. Practically, thermal deformation problem due to high speed is, however, become a large obstacle to realize high precision machining. In this study, therefore, the construction of automatic error compensation system to control thermal deformation in high speed feeding system with real time is proposed. To attain this purpose, high speed feeding system with feeding speed 60mm/min is developed and experimental equation for relationship between thermal deformation and temperature of ball screw shaft using multiple regression analysis is established. Furthermore, in order to analyze thermal deformation error, compensation coefficient is determined and thermal deformation experiments is carried out. From obtained results, it is confirmed that automatic error compensation system constructed in this study is able to control thermal deformation error within $15{\sim}20{\mu}m$.
