To compare response of feeding concentrate mixtere and wheat straw (Group I) with either urea molasses liquid diet (UMLD) as sole ration (group II) or UMLD (similar to protein equivalent of concentrate mixture) plus wheat straw (group III) on intake and utilisation of nutrients and overall performance, twelve crossbred adult male cattle (Holstein Friesian ${\times}$ Hariana) aged about 2.5 years and weighing 342 kg were randomly allotted into three equal groups following completely randomised design and fed respective diets for a period of 60 days. Thereafter, a metabolism trial of seven days duration was conducted to assess nutrient utilisation and nitrogen balance. Animals fed UMLD as sole ration consumed significantly (p < 0.01) less amount of most of the nutrients as compared to other two groups, except crude protein, intake of which was higher in this group but it was comparable between II and III and III and I. On the other hand, digestibilities of nutrients were higher (p < 0.01) in group II, though it was comparable between other two groups, except ADF, the digestibility of which was lower in group II. Inspite of positive nitrogen balance in all the three groups, being significantly (p < 0.01) higher in group I, animals of group II and III lost their body weight especially to the utmost extent in group II, although the amount of energy (TDN) intake were similar statistically. Results indicate that during a scarcity period and economic compulsions, feeding of UMLD can be practised to replace only concentrate mixture from the maintenance ration of adult crossbred cattle for shorter duration as roughage part seems to be essential for the normal functioning of the rumen microbes and overall performance of the animals.
Parenteral nutrition has been an essential part of postoperative care of neonates requiring major surgery who are unable to tolerate enteral feeding for long periods during the postoperative period. However, TPN via central venous catheters(central TPN), used in increasing trend, still presents significant morbidity. To find out whether TPN via peripheral veins(peripheral TPN) could be used as a viable alternative for postoperative parenteral nutrition in neonates, a clinical study was carried out by a retrospective analysis of 53 neonates subjected to peripheral TPN for more than 7 days after surgery. Operations consisted of procedures for esophageal atresia with tracheoesophageal fistula, gastroschisis and omphalocele. Surgery was performed at the Division of Pediatric Surgery, Department of Surgery, Hanyang University Hospitall, from 1983 to 1994. The mean total duration of TPN was 13.3 days (range; 7-58 days), the average daily total fluid intake was 117.6 ml/kg during TPN and 158.6 ml/kg during subsequent oral feeding. The average daily total calorie intake was 57.7 kcal/kg during full strength TPN and 101.3 kcal/kg during subsequent oral feeding. The mean urine output was maintained at 3.5 ml/kg/ hour during TPN and at 3.6 ml/kg/hour during subsequent oral feeding. The increment of body weight observed during TPN was 132 g in TEF, 53 g in gastroschisis and 3 g in omphalocele patients, while loss of body weight was not observed. The mortality rate was 5.7 %(3/53) and was related to the underlying congenital anomalies, not the TPN. The most common complication of peripheral TPN observed was laboratory findings suggestive of liver dysfunction in 23 cases(43.4 %) with no significant clinical symptom or signs in any case, transient pulmonary edema in one case, and generalized edema in one case. None of the major complications usually expected associated with central TPN were observed. The result of this study suggest that peripheral TPN can be used for adeguate postoperative nutritional support in neonates requiring 2 to 3 weeks of TPN.

Influences of Japanese green tea powder (GTP) supplementation to commercial diet on laying performance and egg quality were studied by using 60 laying hens. The experimental diet with or without 0.6% GTP was given ad libitum to the birds during the period from 6 to 71 weeks of age. The birds started egg production from 21 wk of age regardless GTP feeding. Body weight, feed intake, egg weight tended to decrease with GTP supplementation, while egg production rate tended to increase. Haugh unit score was significantly increased with GTP, which accompanied with the increased albumen height. These were observed almost throughout the laying period over 50 wk. Gel proportion in thick albumen was decreased as storage time is prolonged, then higher values of the gel proportion were recorded in the eggs from GTP group. Thick albumen of the eggs from GTP-fed layers had more carbohydrate than that from control layers. All these indicate physical stability of thick albumen in the eggs from GTP group. Thiobarbituric acid content of egg yolk tended to remain lower in the eggs from GTP group during 5-10 days of storage at room temperature. Levels of egg yolk cholesterol and yolk lipid were significantly reduced by GTP feeding. There were no significant differences in eggshell weight, shell thickness and shell strength between the two groups. Thyroid gland and liver from hens slaughtered at 71 wk of age did not differ in weight irrespective of GTP feeding. The present results suggest that GTP could modify components of edible part of egg, leading to the characteristics favourable to consumers such as high durability of thick albumen and less cholesterol in yolk, without altering general performance of the layers throughout this year round experiment.

In order to determine the feeding value of t:1e waste wood of Lentinus eddodes, the waste wood was milled and treated with $Ca(OH)_2$ and cellulase, then raw waste wood and the treated waste wood were fed to broiler chicken and Korean native goates. The results obtained were as follows; 1. The chemical composition of the waste wood was c. protein 2.26%. c. fat 2.57%. c. fiber 44.60 and c. ash 5.58%. No differences were detected between the raw waste wood and $Ca(OH)_2$ or cellulase treated waste wood in chemical composition. 2. In amino acid composition. no cystine and methionine was showed, but trace amount of Vitamin A, $B_1$, and $B_2$, and cholin chloride were detected. 3. Trichoderma viride SANK. No. 16374 was used to decompose the cellulose. 4. In broiler performance, when waste wood meal was subsituted for 5% wheat bran, no adverse effect was showed on weight gain, feed in take and feed efficiency. But $Ca(OH)_2$ and cellulase treated waste wood meal could be subsituted for 8% wheat bran. 5. In Korean native goat performance, feeding waste wood meal subsituted by 50% various bran (25% defatted rice bran and 25% barley bran) had no adverse effect on growth and feed efficiency. 6. Considering the above results, though the waste wood meal could be replaced to part of various bran, there was a bottle-neck to process the waste wood. The waste wood of Lentinus edodes was little feeding value on bed of ruminant.
Diet and feeding patterns of 10 species of gonostomatid fish in the Rockall Trough and Porcupine Seabight, northeastern Atlantic, were investigated as a part of studies analyzing the meso-and upper bathypelagic micronektonic fish communities in these two areas. Copepods were the major food organisms, composing more than 72% in both areas, and ostracods the second most abundant prey organisms (〉13%). The results of stomach content analyses reveals that most of gonostomatids, including two important species, Cyclothone braueri and C. microdon, feed continuously regardless of light cycle and a little at a time. The gonostomatids appear to be planktivores that consume small-sized prey; relative size of most preys was about one-tenth of fish length. These feeding patterns could be an adaptive characteristic of fish living in great deep water where the food items are scarcely present. In general there are no considerable inter-and intraspecific differences, not to mention regional differences, in the feeding of the gonostomatids at both stations except the large specimen of Gonostoma elongatum fed fish. Thus several coexisting species of the gonostomatid fish utilize the same resources, showing competitive relationships.

The one-year onboard training, which has been implemented since 1988 according to the STCW Convention in 1978, is a crucial part of cadets' training and education. The choice of training shipping company is important that like a internship. This basic study is for the satisfaction at the shipping companies that trains cadets the Mokpo National Maritime University. The satisfaction for onboard training consists of a conscious, educational and environmental parts with six demographic characteristics and carried out the questionnaire survey of 206 cadets in shipping companies. The low parts of satisfaction are implemented cross tabulation analysis and in-depth interview for realize the reason. In this paper, the satisfaction from environmental part($3.83{\pm}0.75$) is high but conscious part($3.35{\pm}0.86$) and educational part($3.33{\pm}0.79$) are low. In demographic characteristics, male in gender, apprentice officer in duty, others in kind of crew, container in kind of vessel and 30,000~100,000 tons in size of vessel are high satisfaction in general. Specifically, feeding service($4.02{\pm}0.75$) in environment, influence on future vision($3.65{\pm}0.84$) in consciousness, goal for training($3.50{\pm}0.65$) in education showed the highest level in satisfaction.
This paper presents a development of flexible bowl feeder without mechanical tooling for each specific part to be fed. This flexible bowl feeder is capable of recognising different orientations of components using optical fiber sensors and can be adjusted to feed different components by way of a simple programming method. The system would be suitable for feeding and sorting small components prior to auto,ated small batch assembly.

This study extends the modified linear feedback equalizer (MLFE), normally used for differentially coherent DPSK systems, to the equalization of double differentially coherent PSK (DDPSK) signals. By feeding back into the feedback part after modifying the equalizer output using decision feedback-based demodulation, the proposed equalizer can operate like an equalizer with a decision feedback structure. Simulation results showthat performances of the decision feedback demodulation-based feedback equalizer (DFD-FE) approach those of the DFE/coherent.
The prevalence of iron deficiency in later infancy and the toddler years(25% to 40% at 1 year of age) has not decreased remarkably , except in Western countries. The purpose of this study was to 1) determine the relationship between current feeding practices and iron status, and 2) assess compliance to infant feeding instructions. Two groupsof infants were examined. The first group of 302 infants aged 6 to 24months was seen at a well baby clinic while the second group of 135 infants of the same age group was assessed by venipuncture. Cutoff values for laboratory tests were as follows ; hemoglobin<11g/dL, mean corpuscular volume (MCV) <72fl ; red cell distribution width(RDW)>15% ; serum ferritin level<10ng/ml ; and transferrin saturation (serum iron(TIBC)<10%. The diagnosis of iron deficiency anemia (IDA) was made when a low hemoglobin level was associated with either low ferritin orlow transferrin saturation . Of the 302 children brought to the well baby clinic , 12.3%(n=37) were found to have anemia (hemoglobin<11.0/dL). In terms of children grouped according to feeding practices, it was found that children with anemial comprised 32.0% (24/75) of the prolonged breast-fed group (Group A), significantly more than the 4.0%(7/176) of the artificial milk feeding group(Group B). and 3.9%(2/51) of the switched from breast milk to iron -fortified weaning foods group(Group C).Among the 107 children with IDA , iron deficiency in 105 children(98.1%) was suggested by their dietary histories ; exclusive or prolonged breast-feeding for more than 6 months without iron fortification in 98 infants ; cow's milk consumption> 500ml/day without iron fortification during infancy(n=12), or >800ml without iron-fortified foods after infancy(n=15) ; and the use of unfortified forumula or unbalanced diets, mainly limited to rice gruel. Despite the relatively high (79.6%) motivation on the part of the infants mothers and supervison by professional personnel, the poor results in the infants receiving iron fortified foods were due to poor compliance(85.75). Among the mothers of 98 IDA patients who were contacted by telephone , it was revealed that 29% did not give the oral iron preparation for more than 2 months. Furthermore, negligence or disregard by the parents occurred in 14% of the case , discontinuance of the oral iron preparation by the parents due to side effects occurred in 6%, and the children's refusal or poor oral intake and no further trial occurred in 6%. The dietary history of a large group of infants was highly predictive of their risk for anemia . Continued consumption of breast milk until the age of 1 year is not warranted unless iron-fortified foods are given concomitantly. Because there is a problem with compliance, more successful and safe strategies for preventing iron deficiency woold included dual coverage in the from of therapeutic iron supplementation as well use of iron-fortified foods for teddlers who are at risk of iron deficiency.
Ten experimental tuna long line fishing operations were performed with the long lines A and B, in combination casting orders of BA and AB. The long line B differs from A in its additional main line length per basket and its greater depth of submersion (Table 1). The BA casting order results in an AB hauling order, so that the long line B is casted at an earlier time of a day and fishes for a longer period than A line (fig. 2). The number of fish caught was divided into subclasses in order to be subjected to $x^2-tests$ (Table 2). The first series of $x^2-tests$ were calculated using the hooking rates of two subclasses with other factors pooled (Table 3). The second series of $x^2-tests$ were calculated to obtain the interactions between two subclasses when other factors differed (Table 4). Attention was paid to the extremely small interactions as well as to the large interactions in order to find out whether a factor functions in the same way or in a contradictory way when the other factors involved differ. The test result is summarized in Table 5. The relationship between the hook casting time (relative to the sunrise time) and the hooking rates reveals the feeding behavior of particular species (fig. 3) A high hooking rate for yellowfin tuna shown in the period from one hour before sunrise to the moment of sunrise suggests that they feed actively in that period. Their poor hooking rate on earlier casted hooks suggests that they do not feed well under conditions of darkness and that they feed best while the hooks are sinking. Furthermore it is likely that yellowfin tuna maintain a shallow depth in the daytime, for the $x^2$ interaction between the line casting order BA and AB shows their persistant preferance of the long line A regardless of line casting order. Bigeye tuna show their feeding behavior under conditions of darkness, and show a preference for the sea's deeper layer. Alepisaurus borealis (Gill) show their feeding behavior under conditions of darkness more significantly than the bigeye tuna and their preferance for deep layers is also more significant. Marlins (mainly Makaria mazara) show a feeding behavior which is similar to the yellowfin tuna. The author emphasizes that certain variations of the hooking rates in relation to the line easting time were caused by an inadequate fishing depth as well as by the fish preference for a particular feeding time. When the part of the line casted in pre-dawn hours and hauled in the pre-sunset hours show a significantly lower hooking rate than other parts of the line, then it is concluded that tile hooks settled in a sea layer too deep for feeding.
