Purpose: This study was to identify health needs of the elderly at nursing homes by long-term care grade. Methods: The health needs of 116 elders at two nursing homes in Seoul were measured with resident assessment protocols (RAPs), activities of daily living (ADL), and cognitive performance scale (CPS), and pain and depression were measured by resident assessment instrument (RAI). Results: With regard to RAPs, 11 out of 18 items had different distribution in the 3 groups significantly. The 1st-grade elders had a higher percentage of 9 items than the 2nd- and 3rd-grade ones but the 3rd-grade ones had the highest health needs related with activity. The 2nd-grade elders had similar health needs to the 1st-grade ones. In terms of functional level, the 1st-grade elders had the highest percentage of CPS and ADL but the 3rd-grade ones had the highest score of pain and depression out of the 3 groups. The standardized assessment instrument to identify specific health needs by the 3 groups should be developed. Therefore, care plans to meet health needs of the 3 groups will be made. Conclusion: It is suggested that nursing care is required to the elderly of the 1st- and 2nd-grade and safe activity and environment to the 3rd-graded ones.

The incidence of second-grade milk production in 9 dairy farms of South Korea was investigated from May 2011 to March 2012, and the serum composition of cows producing first- and second-grade milk in 14 farms including the 9 farms was analyzed. The incidence rate of second-grade milk production of 402 cows in nine dairy farms located in the central and southwestern regions of Korea was 15.4% with the highest rate being 34.4%. Seasonal morbidity was higher during late winter (February) and early summer (June) with the highest rate observed in February (32.6%) followed by November (33.3%). Second-grade milk was most frequently found within one month postpartum (34.1%) while only 3.5% was found during the first 60~90 days of lactating period (n=785, 5 herds). The morbidity increased thereafter (P<0.05) with the highest observed between 270~300 days of lactation (36.1%). The acidity was not significantly different between second-grade ($0.159{\pm}0.026%$) and first-grade milk ($0.158{\pm}0.027%$). Blood serum analysis of 371 cows in the 14 dairy farms indicated that aspartate aminotransferase (AST) level was significantly higher (P<0.001) in cows producing second-grade milk while albumin was significantly lower (P<0.001) than cows producing first-grade milk. Total protein and triglyceride was also significantly low along with glucose, non-esterified fatty acid and blood urea nitrogen in cows producing second-grade milk. Statistical analysis including sensitivity, specificity and positive/negative prediction values showed that lactating cows with high AST, low albumin, total protein and triglyceride levels in the serum tended to produce second-grade milk. It was concluded that serological parameters, especially live functional and metabolic-related serum compositions (AST, albumin, total protein and triglyceride), were significantly influenced in cows producing second-grade milk.

Purpose: The aim of this study was to evaluate the relationship between H. pylori infection and recurrent abdominal pain (RAP) in children and to evaluate the effects of eradication therapy on RAP. Methods: From January 1998 to January 2005, 166 children with RAP (61 male, 105 female) aged $10.0{\pm}3.3$ years were included. Upper gastrointestinal endoscopies were performed for all the patients. All H. pylori infected children (n=70) received the eradication therapy and were divided into two groups: Group Ia (n=52); eradicated, Group Ib (n=18); non-eradicated. H. pylori-negative children (n=96) were divided into three groups according to the medication: Group IIa (n=67); no medication, Group IIb (n=13); acid-suppressant, Group IIc (n=16); both acid-suppressant and antibiotics. Questionnaire for symptoms were asked at the first, 6th, 12th, 24th, and 36th months following the treatment (grade 0; completely resolved, grade 1; definitely improved, but there are occasional episodes of mild abdominal pain, grade 2; no change in the frequency and intensity of abdominal pain). Results: In about 90% of H. pylori positive children, RAP improved in the both H. pylori-eradicated and non-eradicated children in a follow-up survey. In about 75% of H. pylori-negative children, RAP also improved among in the three groups of patients regardless of medication. Conclusion: These results suggest that there was no correlations between improvement of RAP and eradication of H. pylori, and between improvement of RAP and medication. Consequently the reassurance that the children with RAP have no serious organic cause was important to improvement of RAP.

In order for investigating the variability of the characters related to malting barley quality of the different seed lots, about 150 seed lots sampled from the six districts in the southern parts of Cheonnam were analysed. The percentages of the first, second, and off grade of different seed lots of inspected malting barley were 25.9%, 62.7% and 11.4%, respectively. The coefficients of variation (CV) for years in the first grade was 25.0% and the off grade 43.4%. The CVs for 1,000 grain weight, assortment rate, grain colour, germination energy and capacity of different seed lots were 9.1%, 13.2%, 35.7%, 6.2% and 5.0%, respectively. Also, the CV for starch content of different seed lots was 4.8% and 9.6% for ${\beta}$-glucan, 14.0% for crude protein, 14.7% for husk rate, respectively. Seventy five percentage of seed lots in the first grade was fitted for the Agricultural Inspection Law of malting barley and the fitted rates in the second and off grade were 90% and 83%, respectively. The grade of malting barley were positively correlated with grain colour, crude protein, crude fiber, husk rate and ${\beta}$-glucan, but negatively with assortment rate, 1,000 grain weight, germination energy and capacity and starch content.

Purpose: To assess the ability of in vivo H-1 MRS to determine the degree of malignancy and to characterize the histopathologic type of intracranial solid tumors. Materials and Methods: In vivo H-1 MR spectra of the pathologically-proven 81 intracranial soild tumors (low-grade glioma 17 cases, high-grade glioma 31 cases, lymphoma 9 cases, meningioma 8 cases, central neurocytoma 4 cases, medulloblastoma 3 cases, PNET 3 cases, metastasis 2 cases, others 4 cases) were analyzed. H-1 MR spectroscopy was performed on a 1.5T MR unit using PRESS sequence with a TR of 2000ms, a TE of 270 or 135ms and a voxel size of $2{\times}2{\times}2cm^3$ for all spectra. N-acetyl aspartate (NAA)/Creatine complex(Cr), Choline complex (Cho)/Cr, and lactate (Lac)/Cr ratios were measured on the peak heights of each resonance and compared among the different tumors. Results: All intracranial solid tumors demonstrated decreased NAA, elevated Cho and lactate, and variable Cr levels. All tumors showed increased Cho/Cr and Lac/Cr, whereas NAA/Cr level was decreased. Mean Cho/Cr and Lac/Cr ratios were significantly higher in high-grade gliomas than in low-grade gliomas. However, NAA/Cr ratio showed no significant difference between low-grade and high-grade gliomas. Very high Cho peaks were seen in lymphomas, meningiomas, medulloblastomas, and neurocytomas in addition to high-grade gliomas. Conclusion: H-1 MRS may be useful in differentiating between low-grade and high-grade gliomas, however cannot characterize the histologic types or subtypes of tumors.

Objectives: This study was carried out with 31, 519(16,653 boys, 14,857 girls) of elementary school students to investigate the prevalence of obesity at a district in Gwangju City. It can be applied to develope an educational program of the obesity control as basic data in this local area Methods: The data collected from May, 2004 to July, 2004 were analyzed by SAS PC+ 8.0 program. Children were selected depending on criteria from obesity index (%) by using physical index (height, body weight), and then subjects were classified into one of three groups according to the degree of obesity: mild(20~29.9%), moderate(30~49.9%), and severe($?50%{\cdot}$) obesity. Results: It showed that male elementary school students were higher and heavier than female elementary school students(p< .001) in every grade except the 4th grade(height) and the 6th grade ( body weight). The obesity rates of male students(11.6%) showed higher(p< .001) than those of female students(8.8%). Specially the 4th grade elementary school boys were higher than any other groups in obesity(13.7%). As a whole, the prevalence of obestiy showed mild(5.9%), moderate(3.8%), and severe(0.6%). Male students showed higher rate of obesity than those of female students. The obesity of male students showed higher rate than that of female students except 2-3rd grade elementary school students(p< .001). The obesity of 4~6th grade elementary school students showed higher rate than those of 1~3rd grade students(p< .001). Conclusions: The obesity rates of male students are higher than that of female students, and the obesity rates of 4~6th grade students are higher than those of 1-3rd grade students in the elementary school. Additionally, these results suggest that the program may be needed to prevent obesity of children.

This study was carried out to make early prediction of carcass yield grade. Sixty six Hanwoo steers were measured for back fat thickness, longissimus muscle area and body weight at 18, 21 and 24 months of age by ultrasound. Carcass evaluation was done after ultrasound measurement at 24 month of age. Ultrasonic yield grade at 18, 21 and 24 month of age were predicted by regression and decision tree methods. Classifying by carcass yield grade, ultrasonic back fat thickness at 18, 21 and 24 months of age was significantly different in each carcass yield grade (p<0.05). The prediction accuracy of carcass yield grade by regression method was 78.8% at 18 months, 86.4% at 21 months and 90.9% at 24 months of age. By using the decision tree method for carcass yield grade, 78.8%, 89.4% and 89.4% of prediction accuracy were obtained at 18, 21 and 24 months of age, respectively.
