  • This experiment was carried out to show a reform measures by grouping for problems by the survey of TMR plants. Twenty total mixed ration (TMR) plants (10 cooperation and 10 private plants) were surveyed, of which 13 plants, 65% of total TMR plants, committed TMR formulae to a outside nutrition specialist (TMR formulator). With respect to consulting fee for TMR formulae, $500{\sim}900$ thousands Won was paid monthly. On the basis of dry matter 1kg, the prices of TMR products were $325.6{\sim}347.0$Won, whereas those of wet TMR products $365.7{\sim}375.0$Won, which was appeared to be factors to increase management cost. And also, because the TMR plants did not provide TDN (total digestible nutrient) value on their products, nutritional balance feeding for cows could not be managed in farms. It was calculated, based on ADF (acid detergent fiber) value, that TDN value in dry type TMR was 63.0% and 73.2% fur private and cooperation TMR plants, respectively and that the corresponding figure in wet type TMR was 64.9% and 67.2%. According to TMR plant employee's opinion, a prier items to enlarge TMR utilization were TMR education, TMR advertisement, and improvement of ability to make TMR formula. Therefore, for the purpose of further development of TMR, special education of persons related to TMR should be supported.

  • Objective : The aim of this study is to observe the effect of Herbal-acupuncture(HA) with Luffae Fructus Retinervus Herbal-Acupuncture Solution(LFR-HAS) at ST36(Joksamni) on Collagen Ⅱ -induced arthritis(CIA) in mice. Methods : DBA1/J mice were immunized with bovine type Ⅱ collagen(CⅡ) on days 0 and 21 to induce an arthritis. The mice were divided into 5 groups. They were Normal group(wild type), Control group(CIA), Saline group(CIA +saline injection), Needle Prick group(CIA +single Prick with an injection needle) and LFR-HA group(CIA +LFR-HA treatment). The saline injection, needle prick and LFR-HA were made on the right ST36(Joksamni) of mice for 5 weeks, 3 times a week beginning 4 weeks after the booster immunization. Results : 1. The highest synovial rate of lung fibroblasts was measured in the 1% LFR-HAS. 2. TNF-${\alpha}$ expression of survival cells from CIA mouse joint was significantly reduced in the 1% LFR-HAS. 3. The incidence of arthritis and the spleen weight of CIA mouse were significantly reduced by the Luffae Fructus Retinervus Herbal-Acupuncture (LFR-HA) at ST36. 4. The concentrations of IL-6, INF-${\alpha}$, INF-${\alpha}$, IgG, IgM, and anti-collagen Ⅱ in the CIA mouse serum were significantly reduced by the LFR-HA at ST36. 5. The histological examination showed that, in the LFR-HA group, the cartilage destruction and the synoviocyte proliferation in the CIA mouse joint were not significant compared to the control group, and the collagen fiber was similarly expressed as the normal group. 6. In the LFR-HA group, the ratio of CD3e+ to CD19+ cell, and the ratio of CD4+ to CD8+ cell in the lymph node were similarly maintained as those of the normal group. 7. CD69+/CD3e+ and CD11a+/CD19+ cells in the CIA mouse lymph node were significantly reduced by the LFR-HA at ST36. 8. CD11b+/Gr-1+ cells in the CIA mouse joint were significantly reduced by the LFR-HA at ST36. Conclusions : These results indicate that Luffae Fructus Retinervus Herbal-Acupuncture (LFR-HA) at ST36 may regulate the immune system and have a therapeutic effect on Collagen-induced arthritis(CIA) in mice.

  • This study was carried out to determine the optimum harvest stage of Italian ryegrass (Lolium multiflorum Lam., IRG) for maximum forage production during the spring season in Suwon, 2010. The variety of IRG was the early maturity type, 'Kowinearly', and six harvest stages (treatments) were first heading (T1), heading (T2), late heading to early bloom (T3), bloom to late bloom (T4), ripeness (T5), and late ripeness stage (T6). The dates of the first heading and heading of 'Kowinearly' were seen on 4 to 5 May, and 14 May, respectively. Plant length and dry matter (DM) percentage at first harvest were from 69 cm and 14.8% at T1 stage to 103 cm and 35.0% at T6 stage, respectively. The content of crude protein (CP) and in vitro DM digestibility (IVDMD) of T1, T2, T3, T4, T5 and T6 at first harvest were 15.6%, 10.6%, 10.1%, 8.1%, 7.3% and 5.4%, and 81.8%, 72.1%, 64.8%, 63.8%, 61.4% and 59.0%, respectively. The content of neural detergent fiber (NDF) and acid detergent fiber (ADF) were increased continuously with delayed harvest. A significantly higher yield of DM, CP and in vitro digestible DM (IVDDM) were observed for T3, and T4 (p<0.05). DM yield of 3,526 kg, 6,278 kg, 7,842 kg, 8,984 kg, 8,346 kg and 8,008 kg/ha, CP yield of 549 kg, 665 kg, 795 kg, 725 kg, 608 kg and 430 kg/ha, and IVDDM of 2,883 kg. 4,526 kg, 5,083 kg, 5,728 kg, 5,124 kg and 4,722 kg/ha at first harvest were recorded in T1, T2, T3, T4, T5 and T6, respectively. Regrowth yield of DM, CP and IVDDM were shown to be higher at T1 and T2 (p<0.05). However, no significant differences were observed between the two stages. Daily DM and DDM production of regrowth IRG were higher at T2, followed by T1. The total yield (at first and at regrowth) of DM, CP and IVDDM were significant higher for T2, followed by T3, T4 and T1 in order. At T2 stage, the yield was 11,089 kg, 1,254 kg, and 7,669 kg/ha in DM, CP, and IVDDM. In conclusion, the late heading to bloom stage was determined to be the optimum harvest stage for a single harvest, while the heading stage was a suitable stage of first harvest of 'Kowinearly' where two harvests were sought in a single year.

  • The nutrient contents of pumpkins depend on many factors, including the species, climate, soil type, and plant part. The nutritional compositions of five pumpkin cultivars (red boujjang, mini hong, mini gold, boujjang, and yakhobak) were investigated. To analyze the nutrient contents of the edible parts, the other parts (seeds, skin, and stem) of each pumpkin were removed. The results showed that the proximate compositions of the edible parts of the pumpkins ranged from 74 to 87 g per 100 g for moisture, 1.6 to 3.2 g per 100 g for crude protein, 10.1 to 20.7 g per 100 g for carbohydrate content, and 2.0 to 3.4 g per 100 g for total dietary fiber. The proximate contents of the pumpkin samples were not significantly different. The thiamine contents of the pumpkins, except for red boujjang, varied from 0.03 to 0.15 mg per 100 g, but that of red boujjang had the highest level (0.60 mg per 100 g). The vitamin C contents of the pumpkins, except for boujjang, ranged from 13.0 to 14.0 mg per 100 g, but that of boujjang was the highest (49.0 mg per 100 g). In particular, yakhobak showed the highest total carotenoid and folate levels (279.5 and $74.0{\mu}g$ per 100 g, respectively). These results will be useful for coming up with better pumpkin varieties through breeding, and established the nutrient compositions of pumpkins.

  • Process input data including material and energy, process output data including product, co-product and its environmental emissions of the reference and target processes were collected and analyzed to evaluate the process performance. Environmentally problematic input/environmental emissions of the manufacturing processes were identified using these data. Significant process inputs contributing to each of the environmental emissions were identified using multiple regression analysis between the process inputs and environmental emissions. Optimum combination of the end-of-pipe technologies for treating the environmental emissions considering economic aspects was made using the linear programming technique. The cement manufacturing processes in Korea and the EU producing same type of cement were chosen for the case study. Environmentally problematic input/environmental emissions of the domestic cement manufacturing processes include coal, dust, and $SO_x$. Multiple regression analysis among the process inputs and environmental emissions revealed that $CO_2$ emission was influenced most by coal, followed by the input raw materials and gypsum. $SO_x$ emission was influenced by coal, and dust emission by gypsum followed by raw material. Optimization of the end-of-pipe technologies treating dust showed that a combination of 100% of the electro precipitator and 2.4% of the fiber filter gives the lowest cost. The $SO_x$ case showed that a combination of 100% of the dry addition process and 25.88% of the wet scrubber gives the lowest cost. Salient feature of this research is that it proposed a method for identifying environmentally problematic input/environmental emissions of the manufacturing processes, in particular, cement manufacturing process. Another feature is that it showed a method for selecting the optimum combination of the end-of-pipe treatment technologies.

  • This study was carried out to investigate cytotoxicity of paraquat on NIH 3T3 fibroblasts, toxicity of paraquat and compensatory effects of 3-methylcholanthrene (3-MC) on the rat lung. In order to conduct MIT [3-(4,5-Dimethylthiazol-2-yl) -2,5-diphenyl -2H-tetrazolium-bromide] and NR (Neutral red) assay, the $5.0{\times}10^4cell/ml$ of NIH 3T3 fibroblast in each well of 24 multi-dish were cultured. After 24 hours, the cells were treated with solution of paraquat (1, 25, 50 and $100{\mu}M$ respectively). After the NIH 3T3 fibroblast of all groups were cultured in same condition for 48 hours. MIT and NR assay were performed to evaluate the cytotoxicity of cell organelles. $MTT_{50}\;and\;NR_{50}$ of paraquat were $1668.97{\mu}M\;and\;1030.85{\mu}M$, respectively. These $IC_{50}$ of Paraquat were decided as a low cytotoxicity by Borenfreund and Puemer (1984). In order to observe the toxicity and compensatory effects of paraquat on the rat lung, Spraque Dawley male rats were used as experimental animals and were divided into paraquat only treated group and simultaneous application group of paraquat and 3-MC, at 30 min and 1, 3, 6, 12, 24, 48 and 96 hrs interval after each treatment. The animals were sacrificed by decapitation and their or the lungs were immediately removed, immersed in fixatives, and were processed with routine method for light microscopic study. Paraffin sections were stained with H&E and iron hematoxylin of Verhoeff. Under the light microscopy, erythrocytes were full in alveolar capillaries at 3 hrs and congested at 24 hrs after paraquat administration. The great alveolar cells (Type II cell) were increased and mitosis of great alveolar were observed in interalveolar septa. Many lymphocytes, macrophages and polymorphonuclear (PMN) cells were observed in connective tissue surrounding lung tissue and germinal center in lymph follicles of terminal bronchiole. Alveolar macrophages were increased in interalveolar septa and alveoli at 48 hrs. And observed many alveolar macrophages at 96 hrs. In iron hematoxylin stain of Verhoeff, Collagen fiber were increased in respiratory bronchiole, interalveolar septa and alveoli and breath of alveoli, and alveolar pore were broaden. But, in paraquat plus 3-MC treated group, morphological changes were mild in lung tissue. These results indicate that 3-MC has a compensatory effects against toxicity of paraquat by conjugation with oxygen.

  • The histochemical characteristics and ultrastructure of the mantle in the spiny top shell, Batillus cornutus were described using light and electron microscopy. The simple epidermal layer wrapped on the top and bottom of the centrally located connective tissue. And then the epidermal layer were divided into the outer epidermal layer near a shell and the inner epidermal layer closed to the visceral mass. The connective tissue layer was composed of the collagen fiber muscularfiber bundle and hemolymph sinus. Mucous cells in the apical mantle contained acid and neutral mucopolysaccaride, and acidic carboxylated mucopolysaccaride in the mid and marginal mantle. The mantle thickness, epidermal layer thickness and hemolymph sinus area displayed a trend of reduction from the marginal zone to the apical zone. From TEM observation, it was possible to distinguish epithelium, ciliated cell, absorptive cell and secretory cell in the epidermal layer. The epithelia were columnar and the nucleus was elliptical. The free surface were covered with microvilli. The lateral membranes of epithelium was con nected with neighboring cells by the zonular occludens, zonular adherens and membrane interdigitation. Ciliated cell on free surface had cilia and microvilli, and numerous mitochondria in the apical cytoplasm. In the epidermal layer, it observed 2 type cells having absorptive function. The absorptive cells were columnar in shape, and contained microvilli, pinocytotic vesicles, mitochondria and lysosomes of various electron density. Secretory cells can be divided into four types (A, B, C, D) depending on the cell shape and characteristics of secretory granules. These cells were unicellular glands and had similar characteristics to previously reported on the mantle of the gastropod and bivalves.

  • This study was conducted to find out suitable rootzone profile, irrigation system, and turfgrass species for roof turf garden. Treatments of profile with soil amendment were Mixture I: Perlite(PL)60%+Vermiculite(VC)20%+Peatmoss(PM)20%, Mixture II: PL60%+VC 10%+PM20%+Sand(SD)10%, Mixture III: PL60%+VC20%+PM20% and Mixture IV: PL60%+VC10%+PM20%+SD10%+Styrofoam 5cm as a drain layer. To test trickle irrigation for roof garden, intervals of main pipe spacing(50cm, 100cm) and drop hole distance(15, 20, 30, 50 and 100cm)were treated, To select most suitable turfgrass species or mixture, Bermudagrass 'Konwoo', Zoysiagrass 'Konhee' and cool-season grass(Kentucky Bluegrass 80% + Perennial Ryegrass 20%, Tall Fescue 30% + KB50% + PR 20%)were tested. In particle size analysis, the soil amendments Perlite and vermiculite showed very even distribution, however, peatmoss contained mostly coarse particles with fiber over $\Phi$ 4.75mm. Under field moisture condition, vermiculite and peatmoss showed 350% water holding capacity, on the other hand, sand or Perlite showed 115% and 166%, respectively. Total weight of soil profile was 139.2kg/$m^2$ with Styrofoam drain layer without sand, which showed most lightest among treatments. Turf quality also resulted positve with Styrofoam drain layer installation. On trickle irrigation system, the proper interval of main drain pipe spacing and drop hole distance were 50cm and 50cm, respectively, In irrigation frequency, once per a day for 15 minute irrigation with 2 1/hr showed the best results on turf quality. Among turfgrass species or cool season grass mixture, warm season turfgrass fine leaf type zoysiagrass 'Konhee' and Bermudagrass 'Konwoo' showed very acceptable result on all over the treatments of rootzone and irrigation system. To apply cool season grasses for the roof garden, advanced researches may be needed to establish the proper soil amendment, rootzone profile, and irrigation system, Application of Bermudagrass 'Konwoo' for roof turf garden also needs successive tests to overcome winter injuries.

  • The objective of this study was to analyze the general and functional components of various soybeans, used for producing soy sauce, tofu, bean sprouts, and for cooking with rice. The moisture, crude protein, crude fat, and ash content of soybeans were in the ranges of 5.50~6.16%, 38.49~41.08%, 14.89~21.89%, and 4.89~5.86%, respectively. Mineral and functional components varied by sample and showed no relationship with usage type. Somyeong for bean sprouts had the highest level of Ca (406.36 mg/100 g), and Sinpaldal for soy sauce and tofu had the highest level of Mg (247.79 mg/100 g). However, Jinpum No. 2 for soy sauce and tofu had the lowest level of Ca (199.51 mg/100 g), and Seonhuk had the lowest level of Mg (90.03 mg/100 g) among the soybeans tested. The isoflavone content in soybeans was in the range of 97.54~402.00 mg/100 g. Somyeong for bean sprouts had the highest level and Seonheuk for cooking with rice had the lowest level. Total oligosaccharides were in the range of $5,838.52{\sim}9,345.90{\mu}g/100g$. Sucrose content was approximately 50% of total oligosaccharides in all samples. Raffinose content was $516.28{\sim}806.95{\mu}g/100g$, and stachyose content was $2,047.13{\sim}3,454.10{\mu}g/100g$. Phytosterols including bracassisterol, campesterol, stigmasterol, and ${\beta}$-sitosterol ranged from 19.25~35.34 mg/100 g. ${\beta}$-sitosterol represented 50% of total phytosterols in almost all samples, followed by campesterol, stigmasterol and bracassisterol. The phytic acid content in soybeans tested was around 2%, except for Sinpaldal No. 2 and Jinpum No. 2 at 0.86% and 1.65%, respectively. The dietary fiber of soybeans was in the ranges of 24.20%~29.20%.

  • Exposure and risk assessments were conducted to evaluate the relative safety of mixing/loading work of indoxacarb between wettable powder (WP) and water dispersible granule (WG). Hand exposure was monitored using cotton gloves while inhalation exposure was measured using personal air monitor. Method validation for the exposure monitoring was established successfully through several experiments. Limit of determination and limit of quantitation were 0.25 and 1 ng, respectively. $R^2$ of calibration curve linearity was more than 0.9999 and reproducibility was 0.7-6. Recovery of indoxacarb from gloves, solid sorbent and glass fiber filter at three different levels was 81.5-108.8%. Trapping efficiency and breakthrough tests gave 981.5-108.8% of recovery. During mixing/loading procedure, hand exposure amount (75 percentile of 30 repetitions) for indoxacarb WP was 6 folds (459.8 mg/kg a.i) than that of WG (81.4 mg/kg a.i). This result indicates that WG has less drift than WP thanks to its granular type of formulation. Inhalation amount was $10^{-8}-10^{-7}%$ of spray mixture prepared and $10^{-4}-10^{-3}%$ of hand exposure. In inhalation case, no significant differences were observed between two formulations. Margin of safety was calculated for risk assessment using male Korean average body weight and acceptable operator exposure level as the important exposure factors. Mixing/loading procedures for both of the formulations were considered to be of least risk because calculated MOS values were more than 1.
