Background: This study was aim to observe the effects of feeding mixed local hay (MH) consisted of 55% orchard grass (Dactylis glomerata L.), 35% tall fescue (Festuca arundinacea) and 10% red clover (Trifolium pratense) to Hanwoo steers on performance, carcass characteristics and meat quality (longissimus thoracis) compared with feeding imported timothy hay (TH) and local rice straw (RS). Results: Although no significant effects were found on animal performance and carcass yield grade, the carcasses of MH group had higher marbling score and quality grade than those of RS and TH group (P < 0.05). Therefore, higher fat content (P < 0.001), lower shear force and hardness value in the beef of MH group than that of other groups were observed. Furthermore, the beef of MH group had higher CIE $a^*$ value (redness) than that of other groups and feeding MH to Hanwoo steers lowered n-6 to n-3 fatty acids ratio in beef. Conclusions: Mixed hay provided benefits on meat quality and could be used for Hanwoo fattening program.

This study was done to investigate mother's attitude to breast feeding and the type of feeding according to the general characteristics of mother. The study sample consisted of 1696 mothers who had an infant and who were visiting five Hospitals or ten Public Health Centers in Seoul. Data was collected through a question aire from June, 1 to June, 30, 1993. The results are as follows : 1. The types of feeding were artificial feeding 2%), mixed feeding(21.7%) and breast feeding (26.1%). 2. The attitude of mothers to breast feeding was very positive for behavior tendency and cognitive attitude but the emotional attitude was low to moderate. 3. The attitude scores for the mothers were from 27 to 60 and 65% the mothers had scores that were high, 50-60 and mean was 49.86. 4. There was the significance between the general characteristics (type of delivery, obtaining in formation on breast feeding, type of feeding and baby's birth order) and the attitude score of mothers. 5. The attitude scores for the mothers by the general characteristics and type of feeding was not a 2-way interaction but the type of feeding had a main effects.

This study was designed to assess the current status of infant feeding through an retrospective survey on feeding method. The survey was executed for 417 mothers bringing up a child below 24 months in Seoul and Kyunggi-Do province from September to October, 1993. Analysing a few influential environmental factors while assessing the level of knowledge today's mother have on infant feeding. Incidence of breast feeding was 27.8% of the interviewed mothers, which showed lower percentages than those of previous surveys. This research proved the major influencing factor generally depended on its mother rather than babies. Generally mothers knew the information of infant feeding, but their knowledge actually didn't work. The source of mothers' informations on the infant nutrition showed the grandmother, books and magazines, doctor were many by the order. among the reasons of resent formula and mixed feeding, lack of breast milk' was the commonest as 50.5% and the next reason was 'because of job' as 12.6%.

The purpose of this research was to obtain information about the performance of breast-feeding by employed mother and the supportive accommodation in the work place. The survey questionnaire was answered by 323 employed mothers who had child over the six months and visited the pediatric clinic in the hospital and the public health center in Seoul. The results were as follows : 1. Of the 323 employed mothers, 4.7% of mothers performed breast-feeding, 58.3% of mothers did artificial-feeding and 37% of mothers did mixed-feeding during the six months after birth of baby. 2. The characteristics of employed mothers found to be related breast-feeding include Age, Education, Number of Baby, Type of Delivery, Place of Delivery, Obtaining Information On Breast-Feeding. 3. The performance of breast-feeding during the work was different significantly according to the mother's job(medical and non-medical) and the method of feeding. 4. The reasons why they could not perform the breast-feeding include not enough time because of working(80.4%) and lack of knowledge about breast-feeding method with combining employment. 5. The results showed that the rest supports of the work environment was insufficient to perform breast-feeding in he workplace except maternal leave.

In order to obtain baseline data for the development of an educational program on breastfeeding, a survey was carried out to investigate infant feeding practices, the characteristics the subjects have in common, and the factors that influence the feeding methods among women in Seoul and the Chungbuk area. Subjects included 671 lactating mothers who visited public health centers or pediatric clinics between December 1999 and February 2000, and were interviewed using a questionnaire. The results were as follows : With respect to feeding methods, the incidence of breastfeeding, formula feeding, mixed feeding and formula feeding switched from breastfeeding was 20.6%, 29.8%, 11.6%, and 38.0%, respectively. With respect to the characteristics the subjects had in common, the incidence of women who planned their infants' feeding methods before pregnancy, during pregancy, and after delivery was 48.7%, 31.0％, and 20.3%, respectively. The incidence of women who started breastfeeding in the hospital after delivery was 38.8％. About seventy seven percet of the subjects had not previously attended an educational program on breastfeeding, and most of these wanted to participate in the future in an educational program to learn about breastfeeding. Some of the topics they were interested in were“Nutritional Management for Sufficient Breast Milk”(60.3%),“Breast Care”(25.0%), and“Correct Nursing Positions”(9.8%). Most (88.2%) of the women who breastfeed suffered from physical discomforts including discomfort of the waist, and legs and discomfort due to cracked or sore nipples. “Insufficient breast milk”was the main reason for breastfeeding cessation or for switching to formula feeding. With respect to formula feeding practices, the main reasons for selecting a specific brand of formula were“the same brand the hospital used after delivery”(34.3%) and“an advertised brand”(23.3%). The strongest factor for promoting breastfeeding was“the support of husband or parents”, next were “breastfeeding in the hospital after delivery”and“planning to breastfeed before pregnancy”in that order. The characteristics the subjects had in common relating to formula feeding were“mother's job”,“high economic level”,“Caesarian section”and “planning to breastfeed after delivery”. In conclusion, it is recommended that breastfeeding be pro-moted, and educational programs be developed and offered as soon as possible to each group which had unfavorable attitudes toward breastfeeding. In addition, the monitoring and supervision of formula advertisements is required to protect consumers from the adverse effects of exaggerated advertising.

This study was to investigate the nutrient intake of infants according to the 3 feeding groups which are as follows : breast-feeding(BF), formula-feeding(FF), mixed-feeding(MF) infants. Intake was compared between these 3 groups and present Korean RDA at 2month of age. The energy and the nutrient intake in the FF infants were significantly higher than in the BF infants and MF infants(p<0.05). Unfortunately, the energy and nutrient intake in all groups still do not meet RDA, excluding iron intake in FF infants. It might be suggested that follow-up study is needed to inspect whether the significant lower intakes of energy and nutrients in BF infants than in FF infants can bring about some significant effects on the growth of the infants.

This study was conducted to investigate the effects of sex, environmental factors, and feeding system on the carcass traits of Hanwoo (Korean Native Cattle). Data were collected from 7,866 heads slaughtered in Chungnam province during one-year period. Using the collected carcass traits data which greatly influence a Hanwoo's carcass grade, the effects of sex class, slaughter season, and feeding system were estimated. Backfat thickness of steers was significantly higher than that of bulls (p < 0.05). Marbling score was also the highest in steers when compared with cows and bulls (p < 0.05). Live weight and carcass weight were significantly higher in winter than in summer (p < 0.05). However, backfat thickness was significantly lower in summer than in other seasons (p < 0.05). Marbling score was higher in spring and fall than in summer and winter (p < 0.05). In terms of feeding systems, TMR (Total mixed ration) and TMF (Total mixed fermentation feed) fed groups showed the highest carcass grade (p < 0.05). However, the group fed TMR and formula feed at the final fattening period showed the lowest performance (p < 0.05) and it is assumed that some stress was associated to the feed change. The results reconfirm that castration may be recommended in order to improve meat quality and marbling scores in bulls. There was no consistent trend of seasonal effects of slaughter on carcass traits although some traits were significantly affected. Regarding the feeding system, either TMR or TMF can be supplied to achieve high feed efficiency and good carcass characteristics in Hanwoo.

Nutrients intake status of 73 lactating women, that is 45 breast feeding (BF), 13 formula feeding (FF) and 15 mixed feeding (MF), living in Daejeon was investigated. Self-recorded food intakes for two weekdays and eating behaviors using questionnaires were surveyed from May to August 2008. Subjects aged $29.2{\pm}3.4$ years and their infants aged $8.2{\pm}3.2$ months. Body mass index of the subjects was $21.0{\pm}3.2$. Of the subjects 23.3% were employed. Daily energy intake was $1953{\pm}391$ kcal. Mean adequacy ratio (MAR) was $0.77{\pm}0.14$ and was higher in FF ($0.86{\pm}0.13$) than in BF ($0.76{\pm}0.11$) and MF ($0.72{\pm}0.18$). Nutrients that over 50% of the subjects took less than estimated average requirement were vitamin A, riboflavin, folate, vitamin C and calcium. And index of nutritional qualities of those 5 nutrients were below one Forty six and sixths percent (46.6%) of the subjects showed GMFVD = 11111 pattern of five food group intakes and 57.5% took meals three times daily, 56.2% skipped often breakfast, and 64.4% dined out two times and more per week. Subjects having lower MAR (< 0.72, n = 24), compared with those having higher MAR (${\geq}$ 0.83, n = 24), showed more skipping daily meals and less frequency of eating-out, and took less legumes, vegetables, fishes, and milk. As the results, intakes of calcium, vitamin A, riboflavin, folate, and vitamin C were insufficient in lactating women, especially in BF and MF mothers. Meal skipping and low intakes of dairy foods, legumes, vegetables, and fishes might have adverse influences on nutritional status of lactating women. Accordingly, nutrition care program for lactating women should be focused on intake of three meals daily and a variety of food.
