The present study was carried out to investigate the serum minerals profile in buffaloes (Bubalus bubalis) suffering from parturient haemoglobinuria (PHU) along with minerals profile of soils and fodders from the disease prone areas and their interrelationships. Serum samples were collected from 60 each of healthy and PHU affected buffaloes randomly selected from field cases. Serum samples were collected from each animal. Fifty composite soil samples were collected where PHU was prevalent. Fifty samples of fodders including leaves and stems being fed to the diseased buffaloes were collected. The difference in the levels of calcium and potassium between upper and lower soil surface of disease prone areas under study were statistically non-significant. The mean values of phosphorous, copper, iron, selenium and molybdenum in upper soil surface were significantly (p<0.05) higher than in lower soil surface. None of the fodders offered to the diseased animals met the dietary requirements of phosphorus and copper whereas none of the fodders was deficient in potassium, iron and selenium rather were having excess of potassium, iron and selenium. The concentration of calcium was adequate in lucerne, berseem, sarson and sorghum, while maize, sugarcane and wheat straw did not meet the required levels for dairy animals. Molybdenum contents in all fodders were adequate to meet the dietary requirements of the dairy buffaloes. Serum phosphorus, copper and selenium were significantly (p<0.001) lower whereas potassium, iron and molybdenum in buffaloes suffering from PHU were significantly (p<0.001) higher than in healthy buffaloes. It was concluded that phosphorous deficient soils play a major role by transferring this deficiency to plants and ultimately reaching to animals where hypophosphataemia is a consistent finding.

The purpose of this study was to classify, from collected home health care records data, nursing diagnoses according to the NANDA system and nursing interventions according to the NIC system, and to link nursing interventions to nursing diagnoses. For this study, 101 home health care records of clients seen between September, 1994 and November, 1996 at Yonsei Medical Center, Seoul, were analyzed. The results of this study are summarized as follows : 1. The most frequent nursing diagnoses were ‘Risk for infection’ and ‘Altered nutrition : Less than body requirements’, then ‘Impaired skin intergrity’ and ‘Ineffective airway clearance’ in the Exchange pattern of NANDA nine human response patterns. 2. The most frequent nursing interventions were the interventions in the Physiological : Complex domain, there were 690(50.7%) interventions among a total 1347 interventions. This results corresponds to Yom, Young Hee(1995)’s research, both Korean and U.S. nurses used the interventions in the Physiological : Complex do main most often on a daily basis. And respiratory nursing interventions were most frequent because 32.7% of the subjects were respiratory patients. 3. The next step was to link the nursing interventions to nursing diagnoses. The most frequent nursing diagnosis was ‘Risk for infection’ and 19 interventions for ‘Risk for infection’ were used 267 times. Then 14 interventions for ‘Impaired skin integrity’ were used 258 times, 12 interventions for ‘Ineffrective airway clearance’ were used 193 times, 12 interventions for ‘Altered nutrition : Less than body requirements’ were used 122 times, 10 interventions for ‘Activity intolerance’ were used 75 times, and 11 interventions for ‘Knowledge deficit’ were used 52 times. 4. The use of standardized classification in the areas of nursing diagnoses and nursing interventions facilitates clinical decision making and prompt nursing activity, and so enhances the effectiveness of nursing care.

The principal objectives of this study were to evaluate the space, equipment, and institution rate by functional area, and to suggest appropriate types, numbers, and equipment capacity by school foodservice size for optimal employee job performance and efficiency. Data were collected and administered by 263 dietitians who attended elementary and middle schools in Gyeonggi Province, and the data were analyzed using SPSS statistical software. Among a total of 72 respondents who provided usable data, 31 (48.6%) respondents were nutrition teachers and 37 (51.4%) were part-time dietitians. The majority of the respondents reported that their foodservices were self-operating types (94.4%), and 8 meals out of 10 meals provided over a 2-week period were served as normal meals, defined as meals consisting of Bab, Kook, Kimchi, and 3 side dishes (73.6%). The mean kitchen space was $186.25\;m^2$ for 500 meals/day, $269.7\;m^2$ for 501 to 1,000 meals/day, $249.1\;m^2$ for 1001 to 1500 meals/day, and $274.87\;m^2$ for 1,500 or more meals/day. The mean space of functional areas was $11.52\;m^2$ for office, $12.63\;m^2$ for storeroom, $9.55\;m^2$ for receiving area, $27.23\;m^2$ for pre-preparation area, $149.9\;m^2$ for cooking area, $18.33\;m^2$ for assembly/service area, $45.50\;m^2$ for dishwashing area, and $17.20\;m^2$ for locker room. Only two pre-preparation and cooking spaces increased significantly with increasing size of school foodservice (p<0.05). Office, cooking area, and locker room were allocated in all foodservices. However, the pre-preparation area (68.7%), receiving area (56.5%), assembly/service area (38.1%), and dishwashing area (37.7%) were lowly installed in the surveyed facilities. Through a focus group meeting discussing the results of this study, appropriate equipment and its dimensions were suggested according to functional areas and foodservice scales. Future studies will be necessary to allocate the appropriate space by functional area with the proposed equipment requirements for optimally efficient decision making in equipment purchasing.

The objective of the current study was to evaluate the effect of supplementation of either L-methionine (L-Met) or DL-methionine (DL-Met) to diets of starter pigs on nitrogen (N) balance, metabolism, and serum amino acid profile. Eighteen crossbred ($Duroc{\times}Landrace{\times}Yorkshire$) barrows weighing $15.45{\pm}0.88kg$ were randomly allotted to 1 of 3 diets with 6 pigs per treatment. The diets included a basal diet (Met-deficient diet) containing 0.24% standardized ileal digestibility Met with all other essential nutrients meeting the pig's requirements. The other two diets were produced by supplementing the basal diet with 0.12% DL-Met or L-Met. The experiment lasted for 18 days, consisting of a 13-day adaptation period to the diets followed by a 5-day experimental period. Pigs were fed ad libitum and free access to water throughout the experiment. Results showed that the supplementation of either L-Met or DL-Met improved N retention, and serum methionine concentration, and decreased N excretion compared with basal diet (p<0.01). The N retention of pigs fed diets supplemented with the same inclusion levels of DL-Met or L-Met were not different (p>0.05). In conclusion, on equimolar basis DL-Met and L-Met are equally bioavailable as Met sources for starter pigs.

The objectives of this study were to investigate the current status of the Korean government-funded meal support program for low-income children through convenience stores and to evaluate the nutritional quality of the meal items available under the program. The POS data of three convenient stores where children had used their electronic meal cards most often in Seoul during January 2010 and the kinds and amounts of ingredients of the meal items available to the children were obtained from the headquarter of the convenient stores. A total of 5,081 transactions by 693 children included in the POS data was analyzed. In addition, nutritional contents of meal items, which were meal boxes (11 kinds), kimbab (13 kinds), rice balls (27 kinds), inari sushi (1 kind), and sandwiches (26 kinds), were analyzed with Can Pro 3.0. The results showed that children had purchased flavored-milk products most often. Children tended to purchase meal items together with drinks (60.9% of transactions), but some purchased drinks (27.6%) or meal items only (11.5%). Except for meal boxes, none of the meal items satisfied 1/3 of Estimated Energy Requirements of the 9-11 year-old boys per day. The average energy contents of different kinds of meal boxes, kimbabs, rice balls, and sandwiches were 619, 357, 200, and 380 kcal, respectively, and the energy content of a package of Inari sushi was 457 kcal. Vitamin C amount was found to be deficient in all the meal items, compared to 1/3 of Recommended Intake of the 9-11 year-old boys per day. The results of this study could be useful to develop nutritionally appropriate meal items for the convenient stores participating in the government-funded meal support program for children from lowincome families.

Selenium is considered to be one of the most controversial trace elements. On the one hand, it is toxic at high doses and there is a great body of information related to environmental issues of Se contamination. On the other hand, Se deficiency is a global problem related to an increased susceptibility to various diseases of animals and humans and decreased productive and reproductive performance of farm animals. Optimisation of Se nutrition of poultry and farm animals will result in increased efficiency of egg, meat and milk production and even more important, will improve quality. From the data presented in the review it is clear that the main lesson which we have to learn from nature is how to use organic selenium in animal and human diets. Selenium-enriched yeast (Sel-Plex) is the result of such a lesson and it is just a matter of time before animal nutrition moves completely from using ineffective sodium selenite to organic selenium. Other lessons from nature will follow. Recent advances in genomics and proteomics, in association with descriptions of new selenoproteins, will be a driving force in reconsidering old approaches related to Se nutrition. Probably 90% of all Se research has been conducted with sodium selenite and we now understand that the natural form of selenium is different. The main advances in Se status assessment and Se requirements were established based on the activity of glutathione peroxidase (GSH-Px), an enzyme which for many years was considered to be the main selenoprotein. Recently it was discovered that it is only one of at least 25 various selenoproteins. Se research and practical applications are developing quickly and they are very exciting and promising.

Dietary intakes and plasma concentrations of retinol and carotenoids were estimated in assessing the vitamin A status of Korean adults living in Seoul and the metropolitan area. Three consecutive 24-h food recalls were collected from 106 healthy subjects (33 males and 73 females) aged 20-59 years. Fasting blood samples of the subjects were obtained and plasma retinol and carotenoids were analyzed. The daily vitamin A intakes ($mean{\pm}SD$) were $887.77{\pm}401.35{\mu}g $ retinol equivalents or $531.84{\pm}226.42{\mu}g$ retinol activity equivalents. There were no significant differences in vitamin A intakes among age groups. The retinol intake of subjects was $175.92{\pm}129.87{\mu}g/day$. The retinol intake of the subjects in their 50's was significantly lower than those in their 20's and 30's (P<0.05). Provitamin A carotenoid intakes were $3,828.37{\pm}2,196.29{\mu}g/day$ ${\beta}$-carotene, $472.57{\pm}316.68{\mu}g/day$ ${\alpha}$-carotene, and $412.83{\pm}306.46{\mu}g/day$ ${\beta}$-cryptoxanthin. Approximately 17% of the subjects consumed vitamin A less than the Korean Estimated Average Requirements for vitamin A. The plasma retinol concentration was $1.22{\pm}0.34{\mu}mol/L$. There was no significant difference in plasma retinol concentrations among age groups. However, the concentrations of ${\beta}$-carotene, lycopene, and lutein of subjects in their 50's were significantly higher than those of in their 20's. Only one subject had a plasma retinol concentration < $0.70{\mu}mol/L$ indicating marginal vitamin A status. Plasma retinol concentration in 30% of the subjects was 0.70- < $1.05{\mu}mol/L$, which is interpreted as the concentration possibly responsive to greater intake of vitamin A. In conclusion, dietary intakes and status of vitamin A were generally adequate in Korean adults examined in this study.

Folate is important for multiple metabolic processes such as nucleic acid synthesis and interconversions, and cell division. Folate deficiency may be a risk factor for several pathologies, such as neural tube birth defects, dementia, and cardiovascular diseases. The objectives of this study were to estimate folate intakes and plasma concentrations of young children living in Kwangju, Korea. Three consecutive 24-h food recalls and fasting blood samples were obtained from 24 boys and 30 girls, aged 2-6 y, living in Kwangju, Korea. The daily folate intake ($mean{\pm}SD$) of the children was $146.7{\pm}73.6{\mu}g$ dietary folate equivalents. No differences in folate intakes were observed by gender ($p{\geq}0.05$). The mean folate intakes of the 2 and 3 y old groups were significantly lower (p<0.05) than those of 5 and 6 y old groups. Over half of subjects consumed $mean{\pm}SD$) of all subjects was $19.2{\pm}8.7nmol/L$, and there was no significant difference by age nor gender ($p{\geq}0.05$). No significant correlation was observed between folate intakes and plasma folate concentrations. One subjeci (1.9%) in this study had a plasma folate concentration <6.8 nmol/L, which is indicative of folate deficiency. Approximately 24% of subjects had plasma folate concentrations of 6.8-13.4 nmol/L, which is representative of marginal folate status. In conclusion, some young children may have less than adequate folate status in Korea.

Twelve growing male lambs ($10.05{\pm}0.41kg$, 5 months age) were assigned to three equal groups in a completely randomized design and fed respectively wheat straw (WS), ammoniated wheat straw (AWS) or urea supplemented wheat straw (USWS) along with concentrate mixtures of varying protein and energy contents to meet their requirements as per NRC (1985). Despite comparable nutrient intake and digestibility, the lambs fed A WS based diet digested lower (p<0.05) crude protein. The digestibility of NDF and hemicellulose were lower while the digestibility of cellulose was higher in lambs on AWS as compared to lambs on USWS based diet. The lambs of all the three groups were in positive and comparable N, Ca and P balance except higher Ca balance in lambs fed WS based diet. The body weight change, average daily gain and feed conversion efficiency were similar among the dietary groups. All the parameters of rumen fermentation pattern were comparable between lambs of AWS and USWS based diets except ammonia-N concentration that was higher in the latter however it was lower in WS fed group. Though, the feeding cost per unit gain was comparable in lambs fed all the three diets, the cost incurred towards roughage during 120 days of experimental feeding was significantly less in lambs fed AWS than UTWS. Thus, feeding of USWS can be practiced to minimize labour cost and environmental pollution involved in the process of urea treatment without affecting the performance of growing lambs.

This study was performed to assess the nutritional status of low income elderly women aged ${\geq}$65 years residing in Gyeongnam Masan (n=124). Nutrition intakes, food intake frequency, and health-related behaviors including smoking, drinking, and exercise were investigated. Nutrition intake was calculated by the 24-hour recall method using CAN-pro (ver. 3.0). Average daily intakes of energy were $1,142.3{\pm}39$ kcal (71.4% of EER) in subjects aged 65~74 years and $1,071.0{\pm}41.7$ kcal (66.9% of EER) in subjects aged ${\geq}$75 years and the subjects consumed energy less than both 75% of estimated energy requirement (EER). The proportions of energy derived from protein, fat, and carbohydrate were 15.4:15.5:70.6 (aged 65~74 years), and 15.3:13.4:70.8 (aged ${\geq}$75). Nutrients consumed at less than estimated average requirements (EARs) were Ca (60.4%), P (98.4%), Zn (91%), vitamin E (48% of adequate intake, AI), vitamin $B_1$ (63.3%), vitamin $B_2$ (54%), niacin (87.7%), vitamin C (62.5%), and folate (50.5%). Especially, the intakes of Ca (58%), vitamin E (41% of AI), vitamin $B_1$ (60%), vitamin $B_2$ (50%), folate (46.5%), and vitamin C (54%) were 75% less than the EAR for people aged ${\geq}$75 years. According to the food intake frequency survey, the intakes of calcium, milk, fruits, and vegetables were very poor. In conclusion, this study suggests that a nutritional support program for elderly women of low socioeconomic class must be provided by the government to improve the quality of remaining life.
