The effects and necessity of the breast milk are well known, but the breast-feeding rate in our country is very low. One of the reason is due to the separation policy of mother and baby after delivery. The mother is in the inpatient-room and the baby is in the new-born baby room. This isolation operation of hospital get increased according to the decreasing ratio of breast feeding in Korea. Only a few hospital operates and provides the space for a new-born baby in the mother's room. The system of baby and mother in one room is adopted and operated due to the breast feeding campaign. It is very encouraging, but the space for the baby and the mother is not enough in multi-bed rooms. We should reconsider the relationship between the new-born baby unit and the obstetric ward, and design the patient's room for the baby and the mother.

Data on available feed resources, feeding practices and nutrient adequacy of rations under small farm conditions in Sri Lanka were obtained in a baseline survey involving 104 pig farms. The results showed that a wide range of non-conventional feedstuffs are used for pig feeding under typical small farm conditions and that dietary protein quality is a major factor limiting productivity. Following the survey, two on-farm trials were conducted to evaluate cheaper, alternative feeding strategies. In trial 1, a test diet was formulated using several non-conventional feedstuffs and compared with a commercial feed that is normally fed in the farms. In trial 2, the possibility of improving growth rates by amino acid supplementation was evaluated. The results demonstrated that feed costs can be considerably lowered through these packages. Some problems inherent to on-farm livestock trials are highlighted.

This investigation aimed to assess the appetite response changes of olive flounder to starving and re-feeding conditions. Three different feeding groups (2 weeks feeding, fed; 2 weeks starving, starved; and 1 week starving and 1 week feeding, re-fed) were established to examine the changes in appetite-related genes for each group. The weight gain of the fish was highest for the fed group and lowest for the starving group. Based on the daily feed intake (DFI) and cumulative feed intake (CFI), overall food intake was found to increase in the re-fed group more than in the fed group from week 1 to week 2 of the experiment. Hypocretin neuropeptide precursor (HCRT) and galanin receptor 1 (GAL-R1) mRNA expression in the brain of olive flounder were decreased in the starved group. Corticotropin-releasing hormone (CRH) was decreased in all experimental groups, except for the fed group. However, overall leptin concentrations in the plasma did not change across groups. Considering the differences between this study and previous studies on starving and feeding, various factors (except the production and expression mechanisms of appetite-related factors in response to starving) are likely acting on the appetite responses of the fish. In this study, a 1-week re-feeding period induced substantial effects on appetite response when compared to a 2-week feeding period. These findings show that even if re-feeding is performed after starving, the unbalance caused by the re-feeding can affect various physiological changes in fish by feed intake efficiency.

A Study was conducted to investigate the effect of feeding Lactobacillus casei YS on the growing performance and gastrointestinal flora of the suckling piglets, which were delivered from 2 heads of three-way crossbred(Landrace$\times$Large White$\times$Duroc) pigs, for 4 weeks. The results from the present study was summarized as follows. Average body weight gains of feeding group was slightly better than that of control group and diarrhea was prevented by successive 7 days feeding. Population levels of lactic acid bacteria were maintained about 107 colony forming unit(cfu) per gram of the contents in both feeding and control group at upper parts of small intestine. In this part, coliform count was greatly reduced in (ceding group but not in control group. pH values of the intestinal contents were gradually decreased especially at the upper part of alimentary track of feeding group. Among lactic acid bacteria, L. salivarius, L. cases and L. fermentum were found most predominant strains in feeding group, Wheareas L. salivarius, L. acidophilus and L. cunts in control group. In the other hand, Escherichia coli recovered from scouring pigs were resistant to the drug such as streptomycin, ampicillin and sensitive to gentamycin and neomycin in vitro test.

A feeding trial was conducted to investigate the effect of feeding frequency on the growth performance and body composition of juvenile mandarin fish Siniperca scherzeri. Triplicate groups of fish (initial fish weight, 7.5 g/fish) were fed to apparent satiation at one, two, three or four meals per day for 8 weeks. The results showed that weight gain of fish fed one meal per day was significantly (P<0.05) lower than those fish fed two, three or four meals per day. Feed efficiency of fish fed two meals per day was significantly (P<0.05) higher than other experimental groups. The plasma cholesterol content was significantly lower in fish fed one meal per day than those fed two, three or four meals per day. Consequently, we can conclude that feeding juvenile mandarin fish twice daily to apparent satiation is acceptable and sufficient to achieve good growth and feed efficiency, as fish performance was not remarkably enhanced when feeding increased from two to four times per day.

Feasibility of the self-TMR mixing/feeding system for dairy farm in Korea was analyzed by comparing with a traditional feeding system. The total operating cost of self-TMR feeding system decreased with an increase of farm size. However, the cost was higher than that of traditional feeding system because of its high purchasing cost of TMR mixer as an initial investment. Profit per unit input of the TMR feeding system became greater over the traditional system when the farm size is larger than 17 heads due to more and better milk production. The profitable discrepancy became bigger as dairy farm size increases.

In this paper, a micro-turning lathe is introduced for micro machining of aluminum rod. To give feed motion, stepwise motion[2] actuators are used instead of the conventional inchworm mechanism. These are consisted of two Piezoelectric ceramics; one is for feeding the slider, and the other is for clamping the slider in the guide way of the body. The guide is V-form. The linearity and positional accuracy of the actuators is good enough far high precision motion. Since the system is more compact than the conventional system using three Piezoelectric ceramics, it is applicable for the micro-machine or MEMS unit. To fabricate the lathe, a small spindle unit with ball bearings of diameter of 10 millimeter is built-up on the top the slider. The motion is feed backed with miniaturized linear encoder attached each axis slider. The diamond tool bite is used for cutting tool. The machining is tried to make small diameter rod. The possible diameter that can be machined in this machine is presented as well as chip formation, surface roughness, and machinability.

Purpose: To analyze the job of nursing unit managers working at women's hospital, using DACUM (developing a curriculum), DACUM is a method for analyzing job-focused competency. Methods: This study involved a descriptive survey. A DACUM workshop was held to define women's hospital nursing unit managers' role and identify their duties and tasks. For the workshop, a committee was formed consisting of 5 women's hospital nursing unit managers. Finally, after validation, the developed contents were made into a survey asking about nursing unit manager's duties and tasks. Results: Sixteen duties and 83 tasks were identified on the DACUM chart. The importance, difficulty, and frequency of the tasks were ranked in terms of A, B, and C, with A being the highest degree. Eight tasks received A's all in importance, difficulty, and frequency of performance. The 8 tasks were: 'taking over', 'taking care of seriously ill patients on handover', 'ward rounding', 'analyzing and resolving demands identified during handover and patient tour', 'reporting patient status during rounding', 'promoting breast-feeding', 'uterine contraction, and training for breast-feeding'. The duty with the biggest determinant coefficient (DC) was 'patients complaint management' (DC=7.09). Based on tasks, the one with the biggest DC was 'solving patient and patient guardian's complaints' (DC=7.53), followed by 'making infection control guidelines' (DC=7.5). Conclusion: When expanding the nursing staff of the hospital, women's hospitals nursing unit managers also need to use administrative functions as intermediaries to focus on the operation management of the entire hospital rather than direct nursing to suit their role.
