With the object of the study id every possible correlation between daily food intake and growth rate of primary school students, aged eleven years old, the author distributed prepared questionnaires through 200 children of 5th grade in both sexes in K private primary school, Seoul. Specific object of this study were included following three points: such as daily food intake records for six days. daily food intake records for six days. school records of sample children at the end of 4th grade. physical growth index calculated by means of weight and height of sample children at the first part of the 5th grade. CR. t. F. test as well as percentage calculations were included for statistical analysis. The result of this study were as follows: 1. For the living circumstances a) Average numbers of brother and sister in sampled family were two to three. b) Approximately 50%of the children were brought up by mother's milk at their infants and about 35% of children were weaned at the age of 7 to 12 months. c) Thirty to forty percent of the respondents revealed irregulity in their meal time due to early school time in the morning. d) Monthly average expenditure for daily food reached 20 to 29% out of total income. e) The most favorit foods reflect as follows: The most favorit main dish is boiled rice mixed with other careals and side dish beaf. Fruits and juice are more popular snack among whole children. 2. Nutrition survey a) The calcium and thiamine were the most limited factors out of daily nutrients consumption. b) The total calory intake were composed of carbohydrate 63%, protein 16% and fat 21% respectively. c) The total food intake were composed of 20 to 24% of animal source of foods and 76 to 80% of plant source of foods (vegetables, grains, fruits) d) The total protein intake were composed of 46% of animal protein and 54% of others. e) The grain stuffs consumed in the largest quantity at the level of 50% out whole food groups. f) Twenty four percent of total food intake came from snack between meal time. 3. The result of statistical analysis were as follows: a) The correlation between the calory intake and plysical growth index revealed statistical significancy at the level of p<0.001. b) The correlation between the protein intake and physical growth index revealed statistical significancy at the level of p<0.001. c) The correlation between the meal time and physical growth index revealed statistical significancy at the level of 0.02

The primary purpose of this research paper is to study the nutrition intake status of high school students and their physical growth and development. Further, it made an attempt to find and define nutritional problems and assist in their growth and development through proper nutritional management. One hundred students in both sexes, first year grade in senior high school were provided with questionnaires. For six days the respondents filled out the questionnaires. They were asked to keep record of what they ate each meal. Their nutritional intake were analyzed in accordance with what they ate. Findings, conducted on percentage, CR test, t test, and F test, were as follows: 1. For the living circumstance a) Average numbers of brother and sister in sampled family were four. b) Seventy to eighty percent of the students were brought up by mother's milk at their infants and approximately 40% of students were weaned at the age of 7 to 18 months. c) Fifty percent of the respondents revealed irregulity in their meal time. d) Monthly average expenditure for daily food reached $20{\sim}40%$ out of total income. e) The most favorite foods reflect as follows: The most favorite main dish is boiled rice and side dish beaf. Fruits. juice, milk, ice cream are more popular snack among whole students. 2. Nutrition survey a) Calory sad nutrients were found to be below the recommended level, especially in calcium, vitamins A, $B_2$ and C. b) The total calory intake were composed of 73% from carbohydrate, 14% from protein and 13% from fat in the case of boys. The girls were 65%, 14%, 21% respectively. c) Both boys and girls in their animal protein intake averaged about 33% out of total protein intake. d) Meat consumption of the majority respondents were proportionate in $10{\sim}20%$ in their total food consumption. 3. The result of statistical analysis were as follows: a) Statistical significant differences in the relationship between the calory intake and physical growth index were observed at the level of p<0.05. b) Statistical significant differences in the relationship between the protein intake and physical growth index were observed at the level of p<0.05. c) Statistical significant differences in the relationship between meal time and physical growth index were observed at the level of 0.02<0.05. d) No statistical significant differences in the relationship among calory, protein intake and school records as well as intelligence were found. The experiment indicated that there is a direct relationship between nutrition and the physical growth and development, whereas There seems to be an indirect relationship between nutrition and intelligence.

The purpose of this study was to evaluate the efficacy and cross-protection of serovar 12 against serovar 4 or 5 of H parasuis with M+$Parapac^{(R)}$. A total of 141 piglets from 2(A and B) farms were used and divided into experimental group and control group in each farm. Farm A has been detected H parasuis serovar 12, whereas farm B has been detected H parasuis serovar 4 or 5 from post-weaned pigs with PMWS. The piglets were vaccinated intramuscularly with 2.0ml of M+$Parapac^{(R)}$ in experimental group or normal saline in control group at 1 week of age. A same booster dose was given at 3 weeks of age. In order to value the antibody titer to H parasuis using by tube agglutination test, blood samples were collected from piglets at the aged of 1 week, 6 and 14 weeks. In experimental group and control group, the average antibody titers were $32.5{\pm}21.0,\;114.5{\pm}34.0,\;98.1{\pm}55.4$ and $32.9{\pm}18.6,\;25.8{\pm}36.9,\; 746.7{\pm}1,215.8$ at the aged of 1 week, 6 and 14 weeks, respectively. The cumulative clinical sign indexes by standard guideline of Schering-Plough Animal Health Corp were 486 and 1,069, respectively. The average daily gains and feed conversion rates were $0.553{\pm}0.016kg$ and $0.492{\pm}0.004kg$, and 1.99 and 2.24, respectively. The average gross lesion scores were $1.0{\pm}0.8$ and $1.9{\pm}0.6$, respectively. According to these results, the M+$Parapac^{(R)}$ containing H parasuis serovar 12 may be induce circulating antibodies that cross-react with serovar 4 or 5 and have a protection of PMWS with H parasuis.

Background: Remarkable progress has recently been made in achieving successful early repair of congenital heart disease with using cardiopulmonary bypass in the neonatal period. The aim of this study is to evaluate our short-term outcomes for performing neonatal cardiac surgery under extracorporeal circulation. Material and Method: Fifty five neonates underwent open heart surgery from February 2002 to December 2007. The mean ages and body weight was 13.5 days. and 3.2 kg, respectively. The diagnoses of the patients were transposition of the great arteries (14), total anomalous pulmonary venous connection (7), large ventricular septal defect (VSD) (7), coarotation of the aorta with VSD (6), interrupted aortic arch (5) and others (16). Result: Six patients had difficulties being weaned from extracorporeal circulation. Four patients left the operating room with an open sternum. Low cardiac output syndrome and acute renal insufficiency were observed in 3 patients each, respectively. Post-operative complications were observed in 27 patients (49.1%). The postoperative mortality was 12.7% (7 patients); 5 patients experienced early hospital death and 2 experienced late death (2). Conclusion: In our hospital, early surgical repair with extracorporeal circulation in neonates was feasible with tolerable mortality. Further follow-up required to establish the long-term survival and complications.

In September 1974, a survey was conducted towards 900 women respondents, each representing a household, residing in 18 selected Myuns(townships) of 18 Guns(counties) in Kyunggi-Do. Fifty households were selected randomly in each Myun and the sample Myuns were also randomly selected from the 18 Guns home-visiting interviews were carried out by Myun level maternal and child health workers with questionnair forms designed to measure the maternal and child health status at each household. Major findings obtained from this survey can be summarized as follows: 1. Of the women responents who were investigated in this survey, 13.1% of them were comprised in the illiterates, indicating no difference in literacy rate from that in most urban areas. 2. Most(93.8%) of the respondents were found to have married at ages of 20-24 years old. 3. Most(85.8%) of the respondents were found to have delivered their first babies at ages of 20-24, while only 13.4% had their first babies at 25-29. 4. About 22% of the respondents had 2 children, while 19% and another 19% had 2 and 4 children, respectively. 5. A great majority of the respondents (78%) experienced not a single death of a child within the family, while about 17% experienced death of one child. 0.7% of the women experienced deaths of 4 or more children. 6. 18% and 17% of the women experienced 4 and 3 pregnancies, respectively, and 12% of them experienced 7 or more pregnancies. 7. About 29% of the women experienced an induced abortion at least once. Nearly 2% of them were found to have experience of 4 or more induced abortions. 8. One half (51%) of the women were found to have received prenatal guidances in the latest pregnancies by (Ub(town) and Myun (township) level maternal and child health workers at least once or more times. 9. 52% women received professional prenatal care in the latest pregnancies: 24% at hospitals or clinics and 20% at health centers. 10. Most (89%) of the last-born children were delivered at home, while only 8.7% were delivered at hospital or clinics. 11. Materials used at delivery comprise vinyl (40%), cement bags (32%) ana gauzed or absorbent cottons (19%). 12. The largest preportion of the attendants at delivery comprises mothers in-law (48). Only 24% were found to be attended by either doctors, midwives or maternal and child health workers. 13. In most (90%) of the deliveries scissors were used to cut the umbilicus. But most (7%) of them used unsterilized scissors, 6 while only 20% of them used sterilized ones. 14. About 68% of the last-born babies were breast-fed for 12 months or more. Those who weaned during 6-12 months were 21%. 15. During 12 months after birth, 65% of the last-born babies were breast-fed, while 24% were given a combination of breast milk and cooked rice. 16. About nine out of the 10 births were found to be registered. 17. 71% of babies received BCG vaccination, while 79% and 56% received samllpox and DPT vaccinations, respectively within a year after birth. Those who were vaccinated against poliomyelitis were about 50%. 18. About 87% of the respondents recogninized the existence of government-sponsored maternal and child health guidance program.

A study was conducted to determine the effect of dietary probiotics or antibiotics on growth and pathological status in growing-finishing pigs. Ninety male pigs weaned at 24 days of age were divided into three groups of 30 pigs each on the basis of body weight and litter. Three groups of ten pigs(one pen) each were assigned to one of the following diets; a control diet or diets containing 0.1% probiotics or 0.1% antibiotics (1:1 mixture of kitasamycin and sulfamethazine). Average daily gain (ADG), feed efficiency(G/F) and the pathological status were monitored. ADG, feed efficiency and carcass quality were not different (P>0.05) among the three treatments. But pork quality in pigs fed probiotics tended to be improved, compared to other treatments. The pigs fed probiotics had lower pathological lesion in intestinal monitoring than that of other treatments pigs. The chemical composition of slurry(BOD, COD, SS, T-N, T-P and ammonia) in the probiotics treatments tended to be decreased, compared to other treatments. Results of this study suggest that dietary probiotics improve pigs' housing environment, and decrease the contents of polluting materials in slurry.

We condicted two experiments to evaluate the interaction among fumaric acid (FA), protected acids (PA), or no additional acid (NO) and two different levels of acid buffering capacity (BC) in diets for 14-d-old weaned pigs. BC was varied substituting mono-calcium phosphate and calcium sulfate for dicalcium phosphate and calcium carbonate. In the high BC diet plus PA, FA was also added. In Exp. 1, 48 gilts were raised for 31 days on the six diets, evaluating growth performance and fecal digestibility. In Exp. 2, 42 gilts were raised. With each diet three subjects were sacrificed after 19 days and four after 38 days. In addition, six subjects were sacrificed at weaning. Growth and carcass performance, ileal digestibility, bacterial populations and pH in the gut were assessed. The piglet performance and stomach, ileal and cecal pH, and empty body composition were not affected by the diets. Empty body composition other than ash content was affected by piglet age (p<0.01). The BC did not influence digestibility. The dietary inclusion of PA improved fecal digestibility of protein (p<0.05) compared to the addition of FA and NO. Ileal digestibility slightly increased with both acid additions (p<0.10), the groups receiving PA showing the higher values. Piglets fed diets with low BC had lower Lactobacillus and E. coli counts in the ileum (p=0.07) and higher Lactobacillus in the colon (p=0.08). Acidified diets tended to reduce E. coli counts in the ileum (p=0.10) and increased Lactobacillus in the colon (p=0.09). The addition in the diet of PA increased Lactobacillus in the ileum compared to the sole addition of free fumaric acid (p=0.07). The addition of protected acids, combined with free fumaric acid in the case of high BC diets, increased protein digestibility and Lactobacillus counts and reduced E.coli counts. Only some changes in the concentration of bacterial population can be expected with a diet of low BC.

Thirty six pre-weaned Barbari kids at 4 months age were reared on four rations computed using coarse cereal grains and by-products of pulses and oil seeds with Crude Protein (CP) and Total Digestible Nutrients (TDN) of 12 and 55% (Low protein Low energy); 12 and 60% (Low protein High energy); 14 and 55% (High protein Low energy); and 14 and 60% (High protein High energy), respectively. After 180 days on feed, male animals ($4{\times}5=20$) were slaughtered to study the effect of diet on carcass characteristics and meat quality. To asses the effect, if any, of such diet on product quality, meat balls were prepared and evaluated for quality changes when fresh as well as during storage ($-20{\pm}1^{\circ}C$). Feeding a ration with CP12 and TDN 60% (LH) to kids produced animals with highest slaughter weight (20.3 kg) yielding higher carcass weight and dressing percentage, lean (65.6%) and fat (6.6%) contents with low bone and trim losses. Although total variety meat yield was markedly higher in HL, the non-carcass fat deposition was relatively higher in LH carcasses. The water activity ($a_w$) of fresh goat meat ranged from 0.994-0.995 and total cholesterol 72.8-90.5 mg/100 g meat. The pH was high in HL and HH meat resulting in decreased ($p{\leq}0.05$) extract release volume (ERV). Meat balls were prepared using meat obtained from goats fed different rations (treatments) and stored at $-20{\pm}1^{\circ}C$. They were evaluated on day 0 and months 1, 2, 3, 4 for physicochemical, microbiological and organoleptic changes. Overall moisture (%), $a_w$, TBA number and pH value were 67.9, 0.987, 0.17, 6.6 respectively and were not affected by treatments except pH that was significantly ($p{\leq}0.01$) lower on LH. As the storage period advanced moisture, pH, $a_w$ and TBA number increased irrespective of treatments. Feeding various diets had no marked effect on microbial load of meat balls but with increasing storage period Standard Plate Count (SPC) and psychrotrophs declined ($p{\leq}0.01$). Treatment LL and LH produced meat balls with better flavour.

Background: The double-lumen cannula (DLC) has begun to be used worldwide for venovenous (VV) extracorporeal membrane oxygenation (ECMO). We aimed to examine whether the DLC could be an effective tool in the treatment of pediatric respiratory failure in Korea. Methods: We reviewed the records of patients weighing under 15 kg who underwent ECMO due to respiratory failure between January 2017 and December 2018. Outcomes of ECMO using a DLC and conventional ECMO using central method or 2 peripheral cannulas were compared. Results: Twelve patients were treated with ECMO for respiratory failure. Among them, a DLC was used in 5 patients, the median age of whom was 3.8 months (interquartile range, 0.1-49.7 months). In these patients, the median values of pH, partial pressure of carbon dioxide, and partial pressure of oxygen were 7.09, 74 mm Hg, and 37 mm Hg before ECMO and corrected to 7.31, 44 mm Hg, and 85 mm Hg, respectively, after ECMO cannulation. Median blood flow rate in the patients treated with ECMO using a DLC was slightly higher than that in the conventional ECMO group, but this difference was not statistically significant (86.1 mL/kg/min and 74.3 mL/kg/min, respectively; p=1.00). One patient from the DLC group and 3 patients from the conventional group were weaned off ECMO. Conclusion: VV ECMO using a DLC provided adequate oxygenation, ventilation, and blood flow rate in Korean pediatric patients with respiratory failure. Further prospective and randomized studies are warranted.

We experienced a case of tuberculosis presented simultaneously with pseudoaneurysm of the aorta and ARDS. A 63-year-old man was admitted with complaints of fever and right upper quadrant abdominal pain for a week. Chest X-ray on admission showed a normal finding. Sub-diaphragmatic abscess on abdomen CT scan was suspected and serosanguinous fluid was aspirated from the abscess pocket. On day 2, he was getting more dyspneic and chest X-ray revealed extensive bilateral infiltration. Aspirated fluid revealed AFB. Later, follow-up abdomen CT scan revealed a leakage of dye from the aneurysmal sac of the descending aorta which was previously diagnosed as sub-diaphragmatic abscess. An aortic stent was placed, covering the opening into the aneurysm. The sputum also showed positive AFB. The patient was successfully weaned from the ventilator, and discharged with anti-tuberculous medication on day 42. Follow-up abdomen CT scan 6 months later showed that the aneurymal sac was completely disappeared.
