To investigate the effect of dietary supplementation with a fermented mixture of bean dregs and wheat bran (FBW) on sow performance. FBW was given to sows during late gestation and lactation; in total, 24 sows were randomly assigned to 4 groups (control diet; 3% FBW diet; 6% FBW diet; 9% FBW diet, n = 6). The weight ratio of bean dregs (wet) to wheat bran was 4:6. Sows were fed different diets from 85 d of gestation until weaning. The results showed that supplementation with FBW increased average daily feed intake (ADFI) during lactation (p < 0.05). FBW supplementation also increased litter weight and milk yield (p < 0.05). The contents of Escherichia coli in the feces of the treatment groups were significantly reduced by FBW supplementation (p < 0.01). FBW supplementation significantly improved the fecal morphology (p < 0.05), alleviating sows' constipation. In conclusion, FBW could increase the ADFI, improve lactation and piglet litter weight in sows and reduce the pathogenic bacterial content in sow feces and constipation.
The preventive effect of Lentinus edodes extract (LE) against constipation was studied in rats. Rats were pretreated with LE contained in drinking water at the concentration of 10%, 20% and 40% over 30 days. Constipation was induced by subcutaneous injection of loperamide (4 mg/kg/day) 3 days prior to sacrifice. Treatment of loperamide resulted in decreases in the number and wet weight of fecal pellets, and increase in the number of fecal pellet in the distal colon and cecocolon weight. In contrast, the number and wet weight of fecal pellets were increased, and the number of fecal pellet in the distal colon and the cecocolon weight were decreased in LE-pretreated groups compared to the loperamide-treated group. Blood parameters such as white blood cell, red blood cell, hemoglobin, hematocrit, platelet, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration, and serum alanine transaminase, aspartate aminotransferase and alkaline phosphatase activities, and blood urea nitrogen and creatinine values were not significantly different between the groups. In addition, LE (0.5 mg/mL) increased spontaneous contractile activity, which was reduced by atropine or loperamide in isolated rat ileum. Theses results suggest that the improvement of constipation symptoms in LE-pretreated rats resulted from a stimulatory effect of LE on intestine contractile activity.

Data collected between 1981 and 1991 at the Philippine Carabao Center at Central Luzon State University (PCC-CLSU) were used for the comparison of growth, milk yield and draughtability of Murrah-Philippine crossbred and Philippine native buffaloes. Body weights and body measurements were available at 3-month intervals from birth to 36 months of age for a total of 34 $Murrah{\times}Philippine$ native buffalo F1 crossbreds (CBB; 21 cows, 13 bulls) and 32 Philippine native buffaloes (PNB; 16 cows, 16 bulls). Lactation records were available for 14 CBB and 19 PNB cows. Data for draughtability under wet and dry ploughing conditions were available for 4 CBB and 4 PNB steers. The results indicate that crossbreds grow faster (0-9 months of age: cows $442{\pm}19$ vs. $301{\pm}21g/day$, bulls $305{\pm}23$ vs. $296{\pm}21g/day$; 9-36 months of age: cows $227{\pm}10$ vs. $147{\pm}12g/day$, bulls $282{\pm}13$ vs. $138{\pm}12g/day$), mature earlier and produce more milk (1st lactation: $1139{\pm}153$ vs. $450{\pm}112kg$; 2nd lactation: $1115{\pm}132$ vs. $488{\pm}136kg$) than native buffaloes, but have a poorer draughtability (wet ploughing; force as % of body weight $8.8{\pm}0.2$ vs. $12.2{\pm}0.6$; dry ploughing: cut depth $10.98{\pm}0.25$ vs. $11.92{\pm}0.13cm$, velocity $0.50{\pm}0.03$ vs. $0.60{\pm}0.02m/sec$, force as % of body weight $9.0{\pm}0.6$ vs. $11.3{\pm}0.7$). The correlation coefficients between body weight and body measurements at birth and at 3-month intervals indicate that heart girth has a relatively high correlation with body weight, especially in crossbreds. It is concluded that in Philippine smallholder farming systems in which meat and milk production are secondary to draught power, the native buffalo is preferable from the point of view of input needed to maintain the number of animals kept for a required draught force.
The purpose of this study was to investigate the effect of antioxidants (vitamin E, selenium, and coenzyme $Q_{10}$) on the bleomycin-induced pulmonary lesions in male rats. Sprague-Dawley male rats were divided into 4 treatment groups ($T_1$, $T_2$, $T_3$, $T_4$) and 4 control groups ($C_1$, $C_1$, $C_3$, $C_4$). The treatment groups of rats weie given a single intratracheal dose of bleomycin (1.5 units/rat) and control groups of rats were given a single intratracheal dose of normal saline (0.15ml/rat). The rats in the $T_1$ group and $C_1$, group were dosed with normal saline (0.5ml/kg/day), the rats in the $T_2$ group and $C_2$ group were dosed with vitamin E (50mg/kg/day), the rats in the $T_3$ group and $C_3$ group were dosed with sodium selenite (3mg/kg/day) and the rats in the $T_4$ gronp and $C_4$ group were dosed with coenzyme $Q_{10}$ (2.5mg/kg/day) intraperitoneally for 7 days or 14 days, respectively. Animals were killed at 7th and 14th day after dosing with bleomycin or saline. The results obtained were as follows: 1. Lung wet weight of treatment groups of rats was increased significantly while body weight gain of them was decreased significantly in comparison with that of control groups of rats (p<0.01). 2. The ratio(%) of lung wet weight to final body weight of treatment groups of rats was increased significantly in comparison with that of control groups of rats (p<0.01). 3. The main histopathological findings of lungs observed in rats at 7th day after dosing with bleomycin were proliferation of the type II alveolar epithelial cells and fibroblasts, increased invading of macrophages into lesions, round cell infiltration and perivascular edema. 4. Lung fibrous tissues were markedly increased in rats observed at 14th day after dosing with bleomycin. 5. Pumonary lesions observed in rats dosed with bleomycin and antioxidants(vitamin E, selenium, coenzyme $Q_{10}$) were not significantly different from those of rats given bleomycin alone.

New Korean-style clay roof tiles have been developed with a focus on significantly reducing the roof's weight while maintaining the strength, absorption rate, and freeze durability. The backflow of rain water through the gaps between roof tiles is prevented by employing baffles and a groove to accelerate water flow. With the new roof tiles, dry construction of a roof is possible without requiring soil. By using the dry construction method with the new roof tiles, a reduction in roof weight of more than 80% is possible compared to the conventional wet construction method with soil. In the case of a traditional Korean-style house with a building area of 99 square meters, the roof weight can be reduced from 135 tons to 24 tons. The new tiles satisfy the KS requirements and are more than 30% lighter than traditional roof tiles. A roof constructed using the new tiles showed no water leaks when exposed to typhoon-class winds with speeds of 17 m/s and 200 mm/h of rainfall, which is 60% higher than the Korea rainfall record. The new roof tiles also have advantages of economic efficiency, workability, maintenance, and aseismicity compared to previous Korean-style roof tiles.
Compostable household wastes(mainly food wastes), after waste papers and cardboard being removed, were daily fed into small bins and mixed thoroughly while the air was supplied into the bin. Three small bins were employed: in case I, only recycled compost was composted, after being once fed at the beginning of composting, in case II, compostable household wastes(less than 50 mm) torn roughly by the hands with recycled compost, and in case III, compostable household wastes(less than 2 mm) ground by a kitchen mixer for vegetables with recycled compost. The straight-line was maintained between the wet or the dry residual mass of composting mixture versus composting time date(the coefficient of determination $R^2{\geq}0.98$ for the wet and $R^2{\geq}0.90$ for the dry). The decomposition rate of each composted material was estimated during composting. The total weight reduction rate after 30 days was 67.86% and 66.14% for case II and III, respectively. For case II, the daily weight reduction 6.82% and the daily decomposition rate 8.81% with the composting mixture, but the daily weight reduction rate was 56.43% and the daily decomposition rate 19.26% with only compostable household wastes. For case III, the daily reduction rate was 6.93% and the daily decomposition rate 7.70% with the composting mixture, but the daily weight reduction rate was 53.30% and the daily decomposition rate 22.95% with only compostable household wastes. The physicochemical characteristics of composting mixture did not show much difference between case II and III as was expected.
A single station representative of the razor clam, Solen (Solen) strictus, on a macrotidal flat, Inchon, Korea was sampled at bimonthly intervals between May 1989 and July 1990 by using a can corer. Estimates of growth rate and annual production of this razor clam have been made using the techniques of cohort growth analysis. Growth rate and production were highest during the first year after spawning and recruitment. The annual production was $2.83g\;DWt/m^2/yr$, mean annual biomass $256.3\;g/w^20$, and a turnover time of 5.00 yea, giving an annual turnover rate (P/B) of $0.20\;yr^{-1}$. The total annual production in wet weight ($33.22g\;WWt/m^2/yr$) appeared to consist of water in live flesh($72.6\%$) and shell($18.9\%$), whereas the dry weight of the soft parts was $8.52\%$, the ash-free dry weight $5.4\%$, and the ash content $3.1\%$ of the total wet weight.
This study was performed to investigate the effect of green sorting before drying on the high-temperature drying characteristics of southern yellow pine dimension lumber(2"${\times}$6"${\times}$12'). To test the advantages of weight sorting, green lumber was seperated into heavy(above 55 1b), medium(50-55 1b), and light(below 50 1b)weight classes. Pieces in each weight class were subgrouped into high(above 35%) and low(below 30%) latewood groups. Groups were dried and seperated by a standard commercial high-temperature schedule; dry bulb temperature $245^{\circ}$ F, wet bulb temperature $180^{\circ}$ F, and air velocity 1200fpm. The results obtained were as follows; 1. There was a highly significant correlation between annual rings per inch(X) and percent-latewood(Y). The regression equation was Y=24, 5047+1.3272X. 2. There were highly significant correlations between either annual rings per inch($X_1$) or percent-latewood($X_2$) a.d specific gravity in green wood(Y). Their regression equations were Y=0.4260+0.0081$X_1$ and Y=0.3749+0.0029$X_2$, respectively. 3. Heavier weight charges dried more slowly than lighter weight charges. 4. Board-to-board variation in green or dry moisture content was less for all seperate weight classes than for unseperated control charges. 5. Lower latewood pieces had higher initial moisture content than higher latewood pieces, and then drying time for lower late wood pieces was longer than higher latewood pieces.

In this study, we investigated the growth of striped mullet (Mugil cephalus), Yesso scallop (Patinopecten yessoensis) and kelp (Saccharina japonica) farmed under the IMTA (integrated multi-trophic aquaculture) system developed by national institute of fisheries science (NIFS). The farmed striped mullets grew from an initial length and weight of $152.5{\pm}12.1mm$ and $41.6{\pm}7.8g$ in October 2013 to $154.2{\pm}5.6mm$ and $47.5{\pm}8.6g$ in November, $160.2{\pm}8.7mm$ and $55.9{\pm}9.1g$ in December and $168.4{\pm}9.6mm$ and $58.4{\pm}8.7g$ in January. The fish continued to grow and reached $190.2{\pm}9.4mm$ in length and $87.5{\pm}8.9g$ in weight in April and $256.4{\pm}9.7mm$ and $156.7{\pm}6.7g$ in October 2014. The daily growth rate (DGR) for total fish length was 0.015~0.1 mm/day during the periods of fast growth and attained 0.038~0.1 mm/day during February ~ March. The kelp grew from an initial blade length and wet weight of $1.19{\pm}0.2cm$ and $0.0028{\pm}0.0012g$ in January 2014 to $3.3{\pm}0.8cm$ and $2.5{\pm}0.9g$ in February and $126.5{\pm}11.6cm$ and $107.4{\pm}22.6g$ in March, after which, erosion occurred and slowed the growth. The DGRs for kelp length ranged 0.03~1.9 mm/day in January 2014 and increased to 0.88~1.9 mm/day during March~April. Increasing water temperatures beginning in April lowered the DGR to 0.03 mm/day. Yesso scallops grew from an initial shell length, shell height and wet weight of $11.83{\pm}0.6mm$, $12.68{\pm}0.7mm$ and in September 2013 to $19.9{\pm}2.5mm$, $20.8{\pm}2.6mm$ and $0.9{\pm}0.04g$ in November 2013. They continued to grow to $45.91{\pm}0.71mm$ in shell length, $42.55{\pm}0.8mm$ in shell height and $12.7{\pm}1.3g$ in wet weight by May 2014 and $60.2{\pm}2.51mm$, $554.6{\pm}2.61mm$ and $24{\pm}2.70g$ by October 2014. The DGRs for shell length of Yesso scallop ranged from 0.02 to 0.256 mm/day with higher values of 0.256~0.27 mm/day during November~December 2013 and March~April 2014.
The benficial effects for perfusion in the preservation of free flaps have been controversial in the clinical and experimental field until now. This study was undertaken to observe the effect of UW solution. a recently developed. high molecular weight. organ perfusion solution. for protection of ischemic injury in normothermic free myocutaneous flaps. Forty rabbits were used in this sutdy. A 1x2x1cm sized gastrocnemius myocutaneous flap based on the feeding vessel from common femoral artery was made. The author set up the ischemic time for 12 hours in these flaps. The flap was washed out with normal saline(control grop, n=10), urokinase(comparative group I, n=10), UW solution before ischemic time(comparative group II, n=10) and UW solution before ischemic time and pentoxifylline before reperfusion(comparative group III, n=10). Afterthen, reperfusion was made for 12 hours. After this procedure, we checked the degree of ischemia and necrosis of myocutaneous flap by gross finding, electrical stimulation test of muscle, triphenyltetrazolium chloride staining and wet/dry weight ratio. The degree of necrosis of comparative group II and III were lesser than control and urokinase group in gross finding(p<0.05). In the electrical stimulation test of muscle, there was no statistical difference between control($1.76{\pm}1.01$) and urokinase($2.36{\pm}\1.02$) group however the muscular power of comparative group II($3.54{\pm}0.93$) and III($3.49{\pm}1.37gm/mm^2$) demonstrated significantly higher than control group(p<0.05). The ischemic findings were found in seven cases of control group and three cases of urokinase group but there were no ischemic findings in comparative group II and III in TIC stain(p<0.05). In the wet/dry weight ratio of flaps in order to evaluate the tissue edema. there was no statistical difference between control($4.55{\pm}0.29$) and III($3.75{\pm}0.48$) were scored significantly lesser than control and urokinase group (p<0.05). These results suggest that perfusion washout with UW solution improves the viability of normothermic free myocutaneous flap by inhibition of cellular swelling.
