This experiment was carried out to determine the value of turfgrass clippings as a source of protein for animal feed. Levels of crude protein(CP) and in vitro dry matter digestibility(JVDMD) were determined for Korean lawngrass (Zoysia Japonica Steud.) under three levels of nitrogen fertilizer ( 0 , 350 and 700kg ha year and three levels of mowing interval between cuts (lO, 20, and 30 days). Sampling was done on the three-year old turffield on which nitrogen and mowing treatments were Imposed. Clippings were collected after mowing, and CP levels were calculated from a measurement of total N(CP = N >< 6.25) l)y Auto-analyser system-2 procedure and IVDMD by Maeng's method which was partly modified with Tilley and Terry's procedure. With the increased nitrogen legime the CP content of leaf clippings varied from 6.6 to 13.6% and that Of stem clippings from 4 to 10.3%. The CP levels of clippings were directly proportional to the N fertilization rate. The highest CP content was recorded in early July when it was 14.1% at 35OkgN ha -and I 18.l%kgN ha-1 with 10-wcek mowing interval. Mowing interval had little effect on the CP content in both leaf and stem clippings. The level of IVDMD in the Korean lawngrass clippings varied with mowing interval. The highest level measured was 47%, hut this varied during the growing season and occurred in the following order : early summer > summer > fall. This experiment has shown that Korean lawngrass clippings can he helpful source of protein for use in some animal feeds and that a high concentration of CP can occur depending upon N fertllizer and that of I VDM I) upon mowing practices.

This research was undertaken to determine the effects of the anticancer and immunosuppressive drug cyclophosphamide (CP) on the epididymis of the male rat in terms of ultrastructural alteration and protein analysis by SDS-PAGE at different groups; control group, 1 week group, 3 weeks group, 5 weeks group were treated with saline (control group) or CP at doses of 20mg/Kg/week, 1 time a week, respectively. In the cytoplasm of the principal cells on the epididymis, the mitochondrial outer and inner membranes were significantly swollen or disrupted. The cisterns of rough endoplasmic reticulum (rER) were also swollen, and a number of Golgi vesicles were increased, respectively. It is suggested that treatment with CP alters the specific cell organelles in all segments of the epididymis. CP caused changes in protein concentrations in cauda of epididymis after CP treatment. Total proteins of 30 to 39 species such as lactate dehydrogenase, carnitine acetyltransferase and acid phosphatase were expressed in the cauda fluid. Then the more CP was increased, the more concentration of proteins caused to decrease, synthesize or increase in epididymal cauda. In contrast to the control group, in particular 29KD and the other 10 proteins in the cauda fluid were decreased or disappeared, respectively, whereas 89KD and the other 6 proteins in the cauda, were increased or synthesized, respectively. The other proteins are not showed distinctive difference. Therefore, it is possible that CP at a high dose accumulation alters epididymal function with dose-related increase or decrease in specific activity of marked proteins for all regions of the epididymis (particularly, specific segment of cauda). These alterations could be mediated by direct, toxic effects of the drug on the epithelium or be secondary to changes in the spermatozoa as a result of the CP treatment.

This paper introduces the Parallel Advanced Loosely coupled Multiprocessor (PALM) architecture, which is based on HCH(m,p), where m is number of links per a communication processor (CP) and p is the number of application processors (APs) connected to the CP. communication links between a pair of CPs and/or between a CP and an AP, are made of dual-Port RAMs, which provide fast and reliable word-parallel communication between processors. Among the wide spectrum of HCH networks, HCH(m,2) is also known to be a cost optimal topology, such that HCH(m,2) consists of the largest number of APs retaining the minimal number of CPs and communication links. We also implement a testbed based on HCH(2,2). The experiment result shows that the small communication/computation ratio of the PALM system would realize fine-grain parallelism on message-passing MIMD systems.

The addition of dietary proteases (PRO) to weaner diets hydrolyzes soybean-based anti-nutritive factors and improves weaned pig's dietary digestibility and growth performance. Therefore, this study explores the effects of PRO in a lower crude protein (CP) level diet than that in a commercial diet on the growth performance, nutrient digestibility, and intestinal morphology of weaned pigs. A total of 90 weaned pigs were randomly assigned to 3 dietary treatments with 6 pigs per pen and 5 replicated pens per treatment using a randomized complete block design (block = body weight [BW]): 1) a commercial weaner diet as a positive control (PC; phase1 CP = 23.71%; phase2 CP: 22.36%), 2) lower CP diet than PC as a negative control (NC; 0.61% less CP than PC), and 3) an NC diet with 0.02% PRO. Pigs fed PC and PRO had higher (p < 0.05) final BW, average daily gain, and/or gain to feed ratio for the first three weeks and the overall experimental period than NC. The PC and PRO groups had greater (p < 0.05) apparent ileal digestibility of dry matter, CP, and energy than the NC group. Moreover, pigs fed PC and PRO increased (p < 0.05) apparent total tract digestibility of CP compared with those fed NC. In addition, the PRO group had a higher number of goblet cells than the PC and NC groups. However, pig fed PC and PRO increased (p < 0.05) villus height and height to crypt depth ratio in the ileum compared with those fed NC. In conclusion, PRO supplementation in a commercial weaner diet with low CP levels improves growth rate and nutrient digestibility by modulating the intestinal morphology of weaned pigs.

Objectives We aimed to investigate the effectiveness of the Korean medical critical pathway (CP) in treating childhood anorexia. Methods In total, 21 patients who met the criteria and agreed to provide information were assigned to the CP group, while 24 patients who met the criteria, agreed to provide information, but disagreed with CP application were assigned to the non-CP group. Demographic, clinical, and economic indices were compared between the two groups. Clinical indices before and after treatment were also compared between the two groups. Results In the CP group, height, weight, body mass index (BMI), BMI percentile, and food approach (FAP) increased significantly after treatment, and numeric rating scale (NRS) and food avoidance (FAV) scores decreased significantly. In the non-CP group, height, weight, weight percentile, BMI, BMI percentile, and FAP increased significantly, whereas NRS and FAV decreased significantly after treatment. Compared to the non-CP group, CP application increased FAP and decreased FAV, medical expenses per consultation, and the total treatment period. Conclusions The application of the Korean medical critical pathway for childhood anorexia is an effective cure system that decreases overall medical expenses with good-quality treatment by means of the standardization of medical practices.

Ceruloplasmin (CP) is the major plasma antioxidant and copper transport protein. Monoclonal antibodies (mAbs) against human CP were produced and characterized. A total of five hybridoma cell lines were established (CP2, CP10, CP20, CP25, CP30). From the epitope mapping analysis, two subgroups of mAbs recognize different peptide fragments were identified. When the purified CP was incubated with the mAbs, the ferroxidase activity of CP was inhibited up to a maximum 57%. Immunoblotting with various tissue homogenates indicated that all the mAbs specifically recognize a single protein band of 130 kDa. They also appear to be extensively cross-reactive among different mammalian including human and avian sources. These results demonstrated that only one type of immunologically similar CP is present in all of the mammalian tissues including human. The CP mAbs could be of great benefit to design the diagnostic kit for CP-related diseases such as Wilson's disease.

The objective of this study was to evaluate the effects of supplements with different crude protein (CP) contents on grazing cattle intake, digestibility, ruminal fermentation pattern, and nitrogen (N) metabolism characteristics during the rainy season. Five ruminal and abomasal cannulated Holstein${\times}$Zebu steers (296 kg body weight, BW) were used in a $5{\times}5$ Latin square design. The animals grazed five signal grass paddocks (0.34 ha). The five treatments evaluated were: Control (no supplement) and 1.0 g of supplement/kg BW with 0, 330, 660, and 1,000 g of CP/kg as-fed. The supplement was composed of starch, soybean meal, urea, and ammonium sulphate. There was a positive linear effect ($p{\leq}0.033$) of the CP content in the supplements on the organic matter (OM), CP, and digested OM intakes. The provision of supplements did not increase ($p{\geq}0.158$), on average, total and ruminal digestibilities of OM and CP. However, the increase in CP content in the supplements caused a positive linear effect ($p{\leq}0.018$) on ruminal digestibilities of OM and CP. Additionally, a quadratic effect of the CP contents of the supplements were observed (p = 0.041) for the ruminal digestibility of neutral detergent fiber corrected for ash and protein, with the highest estimate obtained with the CP content of 670 g/kg. The supply of supplements increased (p<0.001) the ruminal ammonia N concentration, which also changed linearly and positively (p<0.001) according to increase in CP content in the supplements. The apparent N balance and relative N balance (g/g N intake) were not, on average, changed ($p{\geq}0.164$) by the supplements supply. However, both showed a tendency of a linear increase ($p{\leq}0.099$) with increasing supplement CP content. The supplements increased (p = 0.007) microbial N production in the rumen, which also changed linearly and positively (p = 0.016) with increasing supplement CP content. In conclusion, protein supplementation in grazing cattle during the rainy season, while stimulating voluntary forage intake, results in higher efficiency of N utilization when compared to energy supplementation. This is a possible response to increased microbial protein synthesis in the rumen and improved N status in the animal body.

Removal of 4-chlorophenol (4CP) by natural manganese dioxide (NMD) catalyzed reaction was investigated in this study. Tests were also carried out to evaluate the effects of pH and natural organic matter (NOM) on the degradative oxidation of 4CP. Experimental results proved that NMD was effective for the removal of 4CP. Extensive kinetic analysis suggests that overall oxidation of 4CP by NMD is second-order reaction, the first-order with respect to 4CP, and the first-order with respect to NMD, respectively. Also, 4CP oxidation rates on the Mn-oxide surfaces were highly dependent upon experimental conditions such as pH, initial concentration of 4CP or NMD, and existence of humic acid. As pH increased above PZC of NMD, the reaction rate of 4CP was decreased, due to the low affinity of 4CP on NMD at high pH. At pH lower than PZC of NMD, reaction rate of 4CP was also decreased. It was considered that humic acid was involved in the oxidative coupling reaction of 4CP by NMD, resulting in the enhanced degradation rate of 4CP. This study proved that natural manganese oxide can be effectively applied for the removal of chlorophenols in aqueous phase.

A total of 120 growing crossbred pigs ($Landrace{\times}Large$ $White{\times}Duroc$) with equal numbers of barrows and gilts were used in the feeding trial in a $2{\times}3$ factorial arrangement (gender by feeding regimens) to investigate the effect of phase feeding on growth performance during the 25 to 58 kg body weight growth stage, and 6 pigs (three of each sex) were used in a metabolic trial. The growing period was divided into two phases and 4 different CP diets were used to make 3 different feeding regimens (GE18-GL18; 18% CP diets for both early and later growing period, GE18-GL16; 18% CP diet for early and 16% CP diet for later growing period, GE19-GL17; 19% CP diet for early and 17% CP diet for later growing period). There were no significant differences in growth performance among treatments during the entire growing period. However, during the later growing period, feed intake of barrows was significantly higher than that of gilts (p<0.05). Average daily gain of barrows was higher than that of gilts (p>0.05). Based on the result, growth performance differences between barrows and gilts appeared to begin after 40 kg of body weight. There was no significant difference in digestibility among treatments or between sexes. During the early growing period the 18% CP diet showed better digestibility than the 19% CP diet. However, during the later growing period, the 18% and 17% CP diets exhibited similar digestibilities, although 16% CP diet showed slightly lower digestibility than 18% and 17% CP diets. During the early growing period, fecal N and P excretion of pigs fed the 19% CP were higher than that of those fed the 18% CP diet. During later growing period, fecal N and P excretion by those receiving the two phase feeding compared to single phase feeding was reduced by 10.2% and 2.0%, respectively. In the gilts, the cost reduction by two phase feeding (GE18-GL16) compared to single feeding was around 3.81%, but that of barrows was only 0.52%. The results suggested that the same nutrient levels could be applied to barrows and gilts during the growing period. Also, this study suggested the optimum protein and lysine level for early and later growing pigs to be 18% CP, 1.0% lysine and 16% CP, 0.8% lysine, respectively. Feeding two diets to growing pigs, i.e., two-phase feeding, would be more appropriate than feeding a single diet on economic and environmental considerations.
