The present study investigated effects of antifungal and carboxylesterase inoculant on rumen fermentation with different rumen pH. Corn silage was treated without inoculant (CON) and with a mixed Lactobacillus brevis 5M2 and L. buchneri 6M1 (MIX). Rumen fluid was collected from two cannulated Hanwoo heifers before morning feeding (high rumen pH at 6.70) and 3 h after feeding (low rumen pH at 6.20). Dried corn silage was incubated in the rumen buffer (rumen fluid + anaerobic culture medium at 1:2 ratio) for 48 h at 39oC. Eight replications for each treatment were used along with two blanks. Both in a high and a low rumen pH, MIX silages presented higher (p<0.05) the immediately degradable fraction, the potentially degradable fraction, total degradable fraction, and total volatile fatty acid (VFA) than those of CON silages. Incubated corn silages in a low rumen pH presented lower (p<0.05) total degradable fraction, ammonia-N, total VFA (p=0.061), and other VFA profiles except acetate and propionate, than those in a high rumen pH. The present study concluded that application of antifungal and carboxylesterase inoculant on corn silage could improve degradation kinetics and fermentation indices in the rumen with high and low pH conditions.

This study was conducted to evaluate the efficacy of mulberry leaf mixed diet on larval growth of Protaetia brevitarsis. As a result of adding mulberry leaves to oak fermented sawdust, the survival rate of P. brevitarsis larvae were higher than those of the control when mass rearing larvae. When fed oak fermented sawdust with 5%, 10% and 20% of mulberry leaves, the cumulative proportion of larvae over 2.5g was 93.1% at 65 days, 95.6% at 55 days, and 93.9% at 55 days after rearing at 25±1℃, respectively. Also, heavy metals were not detected in larvae of P. brevitarsis fed on mulberry leaves.

The purpose of present study was to investigate the effect of kinesio taping on pulmonary function in stroke patients using manual wheelchairs. Twenty stroke patients were divided into a wood chair group (WCG, n=10), a wheelchairs group (WG, n=10), and a kinesio taping with wheelchairs group (KWG, n=10). Taping with wheelchairs group was applied kinesio taping on back muscles (vertical paraspinal strips and oblique strips). All three groups were trained in upright seated posture for 30 minutes. Pulmonary function tests were performed with forced expiratory volume in one second, forced vital capacity and peak expiratory flow as spirometer. There was a significant increase in forced expiratory volume in one second and forced vital capacity only in KWG. The results of this study demonstrate that kinesio taping has an immediate effect on the improvement of pulmonary function in stroke patients using manual wheelchairs.

This study aimed to determine the effect of McKenzie lumbar support on pulmonary function in Stroke patients. Twenty subjects (n=20) were divided into two groups: a McKenzie lumbar support group (MLS group=10), a control group (n=10). Pulmonary function was performed to assess its effectiveness. A spirometer was used to measure the forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF). The intervention was conducted for four weeks. In the MLS group, FEV1, FVC, and PEF were increased after McKenzie lumbar support. (p<0.05), while no significant differences in the variables were found in the control group (p>0.05). There were no significant differences in variables between the MLS group and the control group (p>0.05). Our findings suggest that applying Mckenzie lumbar support may be an alternative maneuver to improve pulmonary function in stroke patients.

This study used both kinesiotaping and extracorporeal shock wave therapy on patients diagnosed with frozen shoulder - a common musculoskeletal disorder in adults - in order to observe the effects on the joint range of motion. 21 adult(male 12, female 9) were selected and distributed into randomized groups. One group received kinesiotaping (n=10) and the other group received kinesiotaping together with extracorporeal shockwave therapy (n=11). After a 6 week duration of receiving kinesiotaping and extracorporeal shockwave therapy, changes in the joint range of motion in the patients were observed. Post-treatment of frozen shoulder, the changes in abduction within the shoulder joint were as follows: in both groups there was a noticeable increase in the joint range of motion (p<.05). Post-treatment of frozen shoulder, the changes in external rotation within the shoulder joint were as follows: both groups showed a significant increase in the joint range of motion (p<.05). The result of suggest that, it can be inferred that both the extracorporeal shockwave therapy and kinesiotaping are effective in increasing the joint range of motion in patients with frozen shoulder.

In this study, the effectiveness of electrodialysis in removing inorganic arsenic from groundwater was investigated. To evaluate the feasibility of the electrodialysis, operating parameters such as treatment time, feed concentration, applied voltage and superficial velocity were experimentally investigated on arsenic removal. The higher conductivity removal and arsenic removal efficiency were obtained by increasing applied voltages and operation time. An increase of salinity concentrations in arsenic polluted groundwater exerted no effects on the arsenic separation ratios. Arsenic polluted waters were successfully treated with stack voltages of 1.8 ~ 2.4 V/cell-pair to approximately 93.4% of arsenic removal. Increase flow rate in diluate cell gave positive effect to removal rate. However, increase of superficial velocity in the concentrated cell exerted no effects on either the conductivity reduction or on the separation efficiency. Hopefully, this paper will provide direction in selecting appropriate operating conditions of electrodialysis for arsenic removal.

Water dropwort(Oenanthe javanica) is grown usually in submerged paddy field and is widely used as additive in foods like Kimchi, fish soup. However, its cultivation in the under submerged cultivation has been known to cause the reduction in quality of water dropwort plants mainly due to the presence of dirt and some parasites like leeches and water animals. Thus, this study was conducted to evaluate a wetland cultivation(WLC) of water dropwort plants compared to the conventional submerged cultivation(SBC) in the greenhouse paddy field conditions. WLC and SBC treatments maintained water levels to the depth of less than 5cm and about 20cm, respectively. Vegetative stem sections were planted in September and plants were harvested in early April. The results showed that height and yield of water dropwort plants were higher in SBC than in WLC. Total yield per 10a in WLC was 12.3% lower than in SBC (2.34 vs 2.63 tons). However, the useful quality factors such as vitamin C, inorganic nutrients, chlorophyll, and anthocyanin contents were found to be considerably higher in WLC. That is Ca, K, Mg, and anthocyanin contents in the stem were increased 235%, 6%, 143% and 290%, respectively, compared to those of SBC plants. The length of underground internodes from WLC elongated about 2 times more than that of SBC, resulting in an increase in plant length and advance in harvest time. On the other hand, water dropwort plants with wetland cultivation can be produced with good cleanliness and quality, but the cultivation system should be optimized and developed to get more yield the same as SBC.

In this study, a fluorescent silica nano particle is used as the surrogate for challenging test of membrane surface integrity. The particles are functionalized by a fluorescent dying agent so that as an ultraviolet light is imposed a bright fluorescent image from the particles can be taken. If a membrane surface is damaged and has a compromised part larger than the size of surrogate the fluorescent particles would pass through and contained in the permeate. An operator can directly notice whether the membrane surface is damaged or not by detecting a fluorescent image taken from the permeate. Additionally, the size of compromised part is estimated through analysing the fluorescent image in which we surmise the mass of particles included in the permeate by calculating an average RGB value of the image. The pilot scale experiments showed that this method could be applied successfully to determine if a membrane surface had a damaged parts regardless of the test condition. In the testing on the actual damaged area of 4.712 mm2, the lowest error of estimating the damaged area was –1.32% with the surrogate concentration of 80 mg/L, flux of 40 L/m2/hr for 25 minutes of detection. A further study is still going on to increase the lowest detection limit and thus decrease the error of estimation.

The purpose of the present study is to provide exercises, together with music, that are helpful for elderly people’s balancing ability, and to determine their effects in order to provide data for the promotion of elderly persons’health. Thirty elderly persons were randomly assigned to a balance training group(BTG) of 15 subjects, or a music and balance training group (music therapy + balance training [MTBTG]) of 15 subjects; intervention was implemented three times per week for six weeks. To measure the changes in their balancing ability before and after the experiment, the limit of stability, the“Timed Up and Go”(TUG) test, and the Berg Balance Scale (BBS) were measured. Changes in the limit of stability before and after the experiment were shown to be significant in both the BTG and the MTBTG. Changes in the limit of stability of the right side before and after the experiment showed statistically significant differences between the BTG and the MTBTG. Changes in the TUG test and the BBS before and after the experiment were shown to be statistically significant in both the BTG and the MTBTG. The application of music during balance training thus is considered to have a positive effect on elderly persons’balancing ability.
