This study aims to reduce the production cost of mushrooms and therefore boost the income of mushroom producers. The addition of a 10% concentration of herb medicine refuse was adequate for promoting mycelium growth in Flammulina velutipes. A moisture content of 60% in the culture medium was adequate for promoting hyphal growth. The optimum temperature and humidity were $16^{\circ}C$ and 70%-85%, respectively. The average yield of Flammulina velutipes fruting body per 1,100 ml bottle was 275-282 g, which is similar to that of the control. The outbreak of diseases such as mildew and bacterial blotch in mushroom was never observed in the bottle treated with herb medicine refuse. Fewer deformed and second-class quality mushrooms were observed than in the control group. Deviation reduced, and mushroom growth was observed to be significantly uniform. The winter mushroom had a white fruiting body with a hemispherical shape. The diameter of the mushroom cap was 9.2-9.3 mm, stipe length was 12.7-12.8 cm, and thickness was 3.3-3.4 mm; these were almost the same as those in the control group. The partial hardness of winter mushrooms in both the experimental and the control groups showed that the stipe ($54.6-57.3g/cm^2$) is a little harder than the mushroom cap ($46.8-47.6g/cm^2$). The calories and nutrients per 100 g of mushrooms in the control and samples were similar to each other.

Objective: A study was conducted to evaluate the varietal differences among faba bean straws and also to assess the potentials of faba bean straws supplemented with concentrate fed at the rate 70% straws and 30% concentrate mixture on feed intake, digestibility, body weight gain and carcass characteristics of the animals. Methods: Forty yearling Arsi-Bale sheep with initial body weight of $19.85{\pm}0.29kg$ (mean${\pm}$standard deviation) were grouped in a randomized complete block design into eight blocks of five animals each based on their initial body weight. Straws included in the study were from Mosisa (T1M), Walki (T2W), Degaga (T3D), Shallo (T4S), and local (T5L) varieties of faba bean and concentrate (2:1 ratio of wheat bran to "noug" seed cake). The experiment consisted of seven days of digestibility and 90 days of feeding trials followed by evaluation of carcass parameters at the end. Results: Local variety had lower (p<0.05) in grain and straw yield compared to improved varieties but higher in crude protein, metabolizable energy contents and in vitro organic matter digestibility. The apparent digestibility of dry matter and crude protein of sheep fed Walki and Mosisa straws were higher than (p<0.05) straws from Shallo varieties. Sheep fed Walki straw had greater (p<0.05) dry matter intake, average daily gain and feed conversion efficiency than sheep fed local and Shallo straws. Slaughter body weight and empty body weight were higher (p<0.05) for sheep fed Mosisa and Walki straws as compared to sheep fed Shallo straws. Apart from this, the other carcass components were not affected (p>0.05) by variety of the faba bean straws. Conclusion: There is significant varietal differences between faba bean straws both in quality and quantity. Similarly, significant variation was observed in feed intake, digestibility, body weight gain and feed conversion efficiency among sheep fed different straws of faba bean varieties with concentrate supplement. Based on these results, Walki and Mosisa varieties could be recommended as pulse crop rotation with cereals in the study area.

This study was carried out to investigate the changes of blood chemical values in 61 crossbred calves at 1 day, 1 week, 2 weeks, 4 weeks and 9 weeks of age, respectively. The blood chemical values of calves with diarrhea were compared with those of normal calves, and blood chemical values were compared for groups of calves with weight gain divided into four ranges; up to 0.9 kg/wk and over 7.0 kg/wk. The results obtained in this study show that the mean values and standard deviation of red blood cell (RBC) and packed cell volume (PCV) of normal calves at 1 day of age (806.7$\pm $56.5 10$^{4}$/$\mu$l and 33.8$\pm $5.2 %) decreased at 1 week of age and increased at 2 and 4 weeks of age. The PCV of normal calves at 9 weeks of age (32.6$\pm $2.3 %) was significantly lower than that at 2 and 4 weeks of age (p<0.05). Total protein of normal calves at 1 day of age (6.8$\pm $0.5 g/100 ml) decreased to 6.4$\pm $0.6 g/100ml at 1 week and increased to 7.0$\pm $ 0.7 g/100 ml at 2 weeks. After 2 weeks of age, total protein tended to decrease gradually to 9 weeks of age. Glucose of normal calves at 9 weeks of age (78$\pm $4 mg/100 ml) was significantly lower than that at 1 week (110$\pm $8 mg/100 ml) (p<0.01). At all ages, RBC, white blood cell (WBC), PCV and fibrinogen of calves with diarrhea were higher than those of normal calves. RBC and PCV of calves with diarrhea at 1 week of age (929.7$\pm $39.7 10$^{4}$/$\mu$ and 42.3$\pm $0.4 % were significantly higher than those of normal calves at 1 week (786.4$\pm $80.9 10$^{4}$/$\mu$l and 32.2$\pm $3.8 %) (p< 0.05), which suggest that diarrhea at this age can be dangerous. The weekly weight gain was an average of 4.2 kg/wk from birth to 9weeks. RBC, PCV, fibrinogen, total protein and vitamin E of calves with weight gain more than 4.0kg/wk. From the above results we obtained eledata support the importance of providing high quality feed from 4 weeks to 9 weeks of age for satisfactory weight gain of calves.

A study was conducted to determine the physical properties related to drying characteristics, the seasonal air drying curves and the kiln drying schedule for taun lumber imported and utilized. This kiln drying schedule was found by oven drying and developed by pilot testing of green lumber and partially air dried lumber. The results of this study were as follows; 1. Average green specific gravity and standard deviation of heartwood lumber were 0.60${\pm}$0.03 and those of sapwood lumber were 0.64${\pm}$0.02. 2. Radial shrinkage from green to air dry and from green to oven dry were 3.05 percent and 5.96 percent respectively, and tangential shrinkage from green to air dry and to oven dry were 5.49 percent and 8.74 percent respectively. 3. Drying time for 25mm thick green lumber (50 percent moisture content) air dried to 30 percent moisture content were 14 days in springtime. 6 days in summertime, and 12 days in autumntime, whereas for 50mm thick lumber in 36 days in springtime, 18 days in summertime, 38 days in autumntime. 4. Kiln drying schedules developed by oven drying were T8-B3 for 25mm thick lumber and T5-B2 for 50mm thick lumber. 5. Kiln drying curves of green 25mm and 50mm thick lumber were similar to those of partially air dried lumber from the level of 30 percent average moisture content. Green 25mm thick lumber (55.7 percent moisture content) was dried to 9.3 percent moisture content in 101.5 hours and green 50mm thick lumber (65.6 percent moisture content) was dried to 11.5 percent moisture content in 526 hours. 6. End checking for green 25mm thick lumber occured in 49.6 percent moisture content and reached maximum amount in 27.6 percent moisture content and closed in 15.8 percent moisture content. 7. End checking for green 50mm thick lumber and partially air dried lumber developed and reached maximum amount earlier then for 25mm thick lumber. 8. Final moisture content of surface layer for 50mm thick lumber was one half of that of core, and moisture content equalized in the lumber after nine days of room conditioning. 9. Casehardening for 50mm thick lumber was slight and was conditioned after nine days of room stroage. 10. Drying defects, such as end checking and surface checking, were not observed and the quality of dry lumber was first.

The cultivated pearls collected for the study were pretreated through the removal of contaminants and the surface bleaching for easy dyeing. Coloring of pearls are necessary after selecting dyes adsorbable to the Conchiolin layer, a kind of hard protein formed in the seawater, covering the surface of the pretreated pearls. Dyes adsorbable to the Conchiolin layers are mostly basic dyes such as Rhodamine 6G(R6G), Rhodamine B(RB), Methylene Blue(MB) etc. and the binary and ternary competitive adsorption were performed by mixing two or three dyes together. The multi-dye adsorption data were compared with the predictions from the ideal adsorbed solution theory(IASI) combined with the single-dye adsorption model, the Langmuir or the Redlich-Peterson(RP) model. The quality of prediction was compared by using determination coefficient($R^2$) and standard deviation(SSE) values. Predictions from the IAST were found to be in good agreement with the data for the R6G/RB binary adsorption to the pearl layers not fractionated with their size, except for the adsorption data for RB at high concentrations. Among the three binary adsorption systems, R6G/RB, R6G/MB, and MB/RB, only the RB sorption data in the R6G/RB binary system was in poor agreement with the IAST prediction. Competitive adsorption data in ternay systems were in good agreement with the predictions from the IAST except for the RB data.

Purpose : To evaluate the relationship between morphometric analysis of bone microstructure from digital radiographic image and trabecular bone strength. Materials and Methods : One hundred eleven bone specimens with 5 mm thickness were obtained from the mandibles of 5 pigs. Digital images of specimens were taken using a direct digital intraoral radiographic system. After selection of ROI (100 × 100 pixel) within the trabecular bone, mean gray level and standard deviation were obtained. Fractal dimension and the variants of morphometric analysis (trabecular area, periphery, length of skeletonized trabeculae, number of terminal point, number of branch point) were obtained from ROI. Punch sheer strength analysis was performed using Instron (model 4465, Instron Corp., USA). The loading force (loading speed 1 mm/min) was applied to ROI of bone specimen by a 2 mm diameter punch. Stress-deformation curve was obtained from the punch sheer strength analysis and maximum stress, yield stress, Young's modulus were measured. Results: Maximum stress had a negative linear correlation with mean gray level and fractal dimension significantly (p<0.05). Yield stress had a negative linear correlation with mean gray level, periphery, fractal dimension and the length of skeletonized trabeculae significantly (p < 0.05). Young's modulus had a negative linear correlation with mean gray level and fractal dimension significantly (p < 0.05). Conclusions : The strength of cancellous bone exhibited a significantly linear relationship between mean gray level, fractal dimension and morphometric analysis. The methods described above can be easily used to evaluate bone quality clinically.

In this paper, we propose the development of MHLA(Modulatory Hippocampus Learning Algorithm) which remodel a principle of brain of hippocampus. Hippocampus takes charge auto-associative memory and controlling functions of long-term or short-term memory strengthening. We organize auto-associative memory based 3 steps system(DG, CA3, CAl) and improve speed of learning by addition of modulator to long-term memory learning. In hippocampal system, according to the 3 steps order, information applies statistical deviation on Dentate Gyrus region and is labelled to responsive pattern by adjustment of a good impression. In CA3 region, pattern is reorganized by auto-associative memory. In CAI region, convergence of connection weight which is used long-term memory is learned fast by neural networks which is applied modulator. To measure performance of MHLA, PCA(Principal Component Analysis) is applied to face images which are classified by pose, expression and picture quality. Next, we calculate feature vectors and learn by MHLA. Finally, we confirm cognitive rate. The results of experiments, we can compare a proposed method of other methods, and we can confirm that the proposed method is superior to the existing method.
