In this study, focus group interviews were used to investigate female university students' eating behavior, factors related to eating behavior, information sources for nutrition, and formats for nutrition education. Thirty-six students participated in one of five focus groups during December 1998 in Seoul. Focus group discussions were video, audio-taped, transcribed and analyzed by major themes. Results showed that subjects have undesirable eating behaviors, such s eating irregular meals and skipping meals. These behaviors are caused by a lack of time, habit, or for the purpose of losing weight. The students tended to have unbalanced diets and frequently ate out. They had a large amount for dinner and frequently snaked when stressed or had an empty stomach. Most of them were interested in weight control and had attempted to lose weight, but they did not participate in regular exercise. The most frequently used source for nutrition information was the mass media, but much nutrition information was based on what they learned from home economics class during middle to high school. They received more support from mothers, elder sisters, and friends for eating behaviors, such s lowering caloric intake and losing weight. In nutrition education, they wanted to learns behaviorla skills to adopt healthy behaviors, including meal planning, applying scientific weight control methods, exercise that fit into their lives, and stress management. They also mentioned that nutrition screening and assessment should be a part of nutrition education programs. As a method for nutrition education, subjects preferred an individualized approach to group education. These results provide the qualitative information for developing nutrition education programs which will be implemented for Korean University students.

This study was done to analysis data on breastfeeding mothers. This stud was conducted using data from telephone counseling in one metropolitan area. The subjects who had received consultation about breastfeeding were 100 breastfeeding mothers. The period of consultation was from Mar. 9, 1994 to August 23, 1994. Consultants were referred from UNICEF, hospitals, TV, newspapers or magazines. Analysis of the problem patterns resulted in 11 classifications. These were physio -anatomical factors(11 cases) , psychological factors(15 cases), breastfeeding methods(21 cases), breastfeeding intervals and frequency(19 cases) , disease in the breastfeeding mothers(13 cases), disease in the babies (12 cases), lack of support (4 cases), food and drugs while breastfeeding(5 cases), weaning(11 cases), others(27 cases). The highest frequency was for breastfeeding methods (21 cases). When the contents of the counselling were analyzed for the 100 cases, 36 problem patterns were identified. Patterns with over 10 responses were diarrhea, insufficient milk supply, sore and cracked nipples, weaning, inverted nipples and jaundice. The age of infants when mothers were telephoned was as below : 1 week(28 cases), 2 weeks(12 cases), 3-4 weeks(18 cases), 5-8 weeks(7 cases), 9 weeks-3 menths(4 cases), 4 menths-6 months(12 cases), over 6 months(2 cases), and the number of pregnant women was 12. The nursing diagnosis were classified according to problem patterns and each diagnosis was assigned an appropriate Problem Pattern The total number of nursing diagnoses was 22. When clients are referred for counselling nurses need guidelines about problems, possible causes and nursing. In this study, the example of guidelines for sore nipples is suggested. The recommendations based on the telephone counseling results are as follows : Prenatal education about the advantages of breastfeeding and breast care, and home visits after delivery for counseling related to breastfeeding. During the hospital stay, nursing intervention such as education on breastfeeding methods using slides, audio-visual tapes, pamphlets are needed as well as an initial trial of breastfeeding. Further research is indicated on the perceived lack of breast milk and on the effectiveness of nursing interventions to pro-mote breastfeeding.

The connectorless power supply system on that multi-contact causes confidence when the wiring reconstructed in the rear. As you see above, contact points between sets and indoor space cause inferior function of audio frequency so it needs to be eliminated. This paper explains the structure of connectorless power supply to supply the system with power crossing the air gap in the part of inductively in the connectorless power supply of both magnetic and electrical model. To get maximum output of electrical load, compensating capacitor compensates to show inter-inductance, lequeage-inductance reducing the track-inductance and access the conditions for resonance. At that time it accesses the maximum electric power. The small change of the value of compensating capacitor causes the changes of maximum electric power. Here the power electronics technology is used not only in the industrial machinery but also in the home appliances so the switching power supply is used to actualize the miniaturization, lightweight, and high efficiency. Generally the condenser input methods are widely used in the rectification circuit of switching power supply, but condenser input method generate great quantity of high frequency components because with this method the current flows in the power input filtering condenser only around value of peak of ac input voltage. To solve these problems, installation of power factor improve circuit on the front of filtering capacitence was considered. Several methods were suggested regarding, but the active filter method which makes smalliging and highly power factor possible are the produce main stream. IC for power factor improvement can be utilized by CMOS process proposing low power consumption. When the high power factor is considered seriously in the power factor improvement circuit, active filter method is selected. In the active filter method, the boost converter is used. Regarding this ·the boost converter is needed.
