The study, published in the 2007 revised curriculum of Practical Arts and Technology and Home Economics textbook(16 species) of the 'human development and family members' area of learning content elements were analyzed. This analysis was conducted in order to evaluate that the 2007 revised curriculum of Practical Arts(Technology and Home Economics) has been made well Articulations. The criteria of Articulations is "Development of learning content, Repeating, Gaps, Reduction. Content criterias is 'human development and family' area. These include "human development, human relationships, marriage and family life, caring for family members and family welfare" of the four criteria and 14 content elements. The results of this analysis, the first content elements is "process of human development, characteristics of human development, family relationships, communication, dating and partner selection, the significance of marriage and family, understanding the basic concepts of family, family change and family problem solving". There was no content elements. content element is 'friendship'. content elements is 'Characteristics of human development', 'understanding of sex and pregnancy and childbirth'. Thus, in the new curriculum, a review of these Articulations are required. Especially, the 'friendship' and 'understanding of sex and pregnancy and childbirth' of the content element should be noted in the curriculum configuration because of content elements be Analyzed as or . Also 'values about marriage change' importance in the low fertility society is a big learning content elements need repeating. However, textbooks should reflect differences in the configuration will hakgyogeupgan. Meanwhile, 'changes in values about marriage' that it is necessary to deal with the repeatedly because of recentely society is The low fertility society, However, for this content element based on the differences between school level to appear the contents of textbooks, the textbook screening process will be provided with the correct guidance.

Purpose : With the recent improved survival of extremely low birth weight infants(ELBWI), enteral feeding has become a major issue. This study investigates the effects of early enteral feeding in ELBWI on their morbidity, duration of hospitalization, and mortality. Methods : ELBWI admitted to the neonatal intensive care unit at Samsung Medical Center from November 1994 to April 2004 who survived more than 14 days were enrolled. ELBWI were divided into two groups : an early feeding group(EF), in which enteral feeding was started within 3 days after birth; and a late feeding group(LF), in which enteral feeding was started beyond 3 days after birth. 80 ELBWI came under EF, and 131 ELBWI under LF. Results : Birth weight and gestational age did not differ between the two groups. In EF, the time to achieve full enteral feeding and the duration of parenteral nutrition were significantly shorter than in LF. The incidence of bronchopulmonary dysplasia was significantly lower in EF, but the incidences of sepsis, necrotizing enterocolitis, and cholestasis were not different between the two groups. There was no difference in the survival rate between the two groups, but the duration of hospitalization was significantly shorter in EF. Conclusion : Early enteral feeding in ELBWI did not increase the incidence of necrotizing enterocolitis and sepsis, but rather decreased the incidence of bronchopulmonary dysplasia and shortened the duration of hospitalization.

Physicochemical properties and mineral composition of seaweed salts prepared by incineration and osmotic dehydration methods were determined. As the incineration temperature increased, yield of seaweed salts, insoluble solids, pH, alkalinity, and oxidation-reduction potential (ORP) decreased. Alkalinity of salt prepared with sea tangle was higher than that of sea mustard. ORP decreased by incineration above $700^{\circ}C$, and was lower in salt with sea tangle. As incineration temperature increased, amounts of K and Ca in seaweed salt increased, whereas that of Mg decreased. Potassium and Ca contents of seaweed salt increased remarkably compared with those of common salt. Potassium content of sea tangle salt was higher than that of sea mustard. As incineration time increased, yield of seaweed salts, insoluble solid content, and pH decreased, whereas ORP of the salt increased. Potassium content of seaweed salt with incineration time, while Ca and Na contents decreased after incineration of 8 and 4 hr, respectively. Yield of seaweed salt by osmotic dehydration increased as immersion time in sea water increased. pH of salt from sea mustard was higher than that of sea tangle. ORP of seaweed salt dried three times was -128.8 mV, significantly lower than that of salt prepared by incineration method. As sea water immersion time increased, Mg content of seaweed salt increased significantly, while Ca content decreased. Potassium content of seaweed salt was higher in sea tangle salt. In case of salt prepared by incineration of residuals, pH increased with immersion time but ORP decreased.
