The primary purpose of this study is to develop system modules of school buildings and the seismic loss function of the system modules for regional loss assessment of school buildings. System modules of school buildings were developed through statistical analysis of school facilities in Korea. The structural system of school buildings with non-seismic details is defined as reinforced concrete with partially masonry walls (RCPM), and 27 system modules of RCPM were developed considering the number of stories, spans, and the age of the building. System modules were designed to assess the structural behavior by applying the shear spring model and the shear failure of the columns of the school building. Probabilistic seismic demand models for each component of system modules were derived through nonlinear dynamic analysis to determine the relationship between seismic intensity, drift ratio, and peak floor acceleration of system modules. The seismic loss function was defined as the total damage ratio, which is the ratio of replacement cost to repair cost to evaluate the seismic loss quantitatively. The system module-based seismic loss well predicted the observed data. It will be possible to help many stakeholders make risk-informed decisions for a region through the regional loss assessment of school buildings in Korea.

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.

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.

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.

The goal of this study was to assess the effect of a group exercise program on cognitive function of elderly people. Subjects were chosen to be elders with dementia having minor to moderate degrees of cognitive function. Study was started out by randomly dividing the 16 subjects into two groups, each with 8 people; the group exercise group and the control group. The group exercise group performed 8 weeks of group exercise program and general physiotherapy while the control group only performed general physiotherapy. Cognitive function was measured by Korean version mini-mental state examination. The study group's attention and calculation statistically significantly improved but the control group saw no statistically significant change. The group exercise program affected improvement in cognitive function of elderly people with dementia and in particular, was effective for enhancing their attention and calculation.

The fact that flip-flops, one of many different types of unstable shoes, are light and relatively easy to put on, accounts for their popularity among people. But because flip-flops rely heavily on the support of a single thong between your first and second toes, they impose a huge amount of pressure onto lower leg. Thus in the following experiment we tried to examine the different effects of flip-flops and running shoes in terms of their effect on muscle activity and fatigue of tibialis anterior and gastrocnemius during walking. In order to measure an electromyogram we used Free EMG system. 10 men and 10 women in running shoes ran on treadmills for 15 minutes at 4.8km/h, 2 days later the same experiment was carried out, but this time, in flip-flops. p value turned out to be greater than .05 and thus there was no considerable difference between the effects of flip-flops and running shoes on muscle activity and fatigue during walking. Therefore we conclude that despite the fact that flip-flops are considered unstable, their effects on muscle activity and fatigue of tibialis anterior and gastrocnemius are negligible.

The purpose of this study was to examine the influences of chronic shoulder pain on the muscle tone in trunk muscles. The study's subjects were 40 men and women in their 30 to 50s, which were divided into two groups. A chronic shoulder pain group consisted of 20 subjects who had been diagnosed with chronic shoulder pain by doctors, and a painless group consisted of 20 subjects who had experienced no such pain. An analysis was performed using electromyography on the muscle tone in the rectus abdominalis, external oblique, internal oblique, and erector spinae muscles under the same conditions between the two groups. The analysis results were as follows. The chronic shoulder pain group exhibited an overall high level of trunk muscle tone than the painless group, along with a statistically significant difference in the rectus abdominalis(p<.05). Moreover, the chronic shoulder pain group showed differences in the trunk muscle tone depending on the affected side. The chronic left shoulder pain group yielded higher levels of muscle tone in the right-side trunk muscles. In particular, the group revealed statistically significant differences in the rectus abdominalis and internal oblique(p<.05). The chronic right shoulder pain group exhibited higher levels of muscle tone in the left-side trunk muscles with a statistically significant difference in the internal oblique(p<.05). The above results suggested that chronic shoulder pain influences increases in the muscle tone in the trunk muscles on the opposite side to the affected shoulder.

This study aims to address the effect of interferential current therapy and thereby to provide basic resources to physical therapies for internal medicine by identifying symptoms for functional dyspepsia and serum gastrin level that shows gastric motility. Following results were obtained by performing interferential current therapy to 16 subjects composed of 8 for functional dyspepsia group and 8 for control group for 20 minutes a day, 3 days a week, for 6 weeks. In control group, serum gastrin level was significantly( p<.01), lowered after the therapy whereas there was no significant difference observed in all questions from questionnaire for symptoms of functional dyspepsia between before and after the therapy. In functional dyspepsia group, serum gastrin level was significantly(p<.01), lowered after the therapy and there was also significant(p<.01) reduction in every question from questionnaire for symptoms of functional dyspepsia between before and after the therapy. There was more significant decrease in serum gastrin level and reduction in questionnaire for symptoms of functional dyspepsia in the functional dyspepsia group compared to the control group(p<.01). This study confirms the interferential current therapy as an effective therapeutic method for internal diseases including functional dyspepsia since it not only improves the symptoms of functional dyspepsia but also allows the gastric motility close to normal.

Beet armyworm, Spodoptera exigua are difficult to control using chemical insecticides because of the development of insecticide resistance. For eco-friendly beet armyworm managements, various control agents are required. Entomopathogenic fungus is one of promise control agents as an alternative to chemcal control agent. We conducted bioassays with entomopathogenic fungi to select high virulence isolate to larva of beet armyworm. The bioassay was used 150 entomopathogenic fungal isolates which were isolated from soil samples of nine provinces by insect-bait method using Galleria mellonella and Tenebrio molitor. . Three isolates, Metarhizium spp. FT83, FT89 and FT90 had high virulence as 84.6%, 100% and 100%, respectively, against S. exigua. The medial lethal time(LT50) of conidia of three isolates was 5.01, 2.99 and 2.92days respectively.

The purpose of this study was to examine the degree of knowledge of care workers working at long term care hospitals and nursing homes on pressure ulcer. A total of 81 care workers including 34 at long term care hospitals and 47 at nursing homes were surveyed. 24 questions were used to evaluate their degree of knowledge on pressure ulcer. Their knowledge on pressure ulcer scored 12.84 out of the total score of 24 points(SD=3.40), which was equal to 53.50 (SD=24.23) out of 100 points. Their knowledge on the prevention of pressure ulcer was highest among the subareas of evaluation. Their knowledge on pressure ulcer statistically significantly differed according to education on pressure ulcer(P<.05). A pressure ulcer is a skin disorder that may be prevented and cured. At this point when long term care facilities are rapidly increasing, care workers highlevel knowledge on and good management of pressure ulcer is very important. Practically educating them on pressure ulcer including the provision of recent, updated relevant knowledge will be necessary.

The majority of strokes are caused by ischemia and result in brain tissue damage, leading to problems of the central nervous system including hemiparesis, dysfunction of language and consciousness, and dysfunction of perception. The purpose of this study was to investigate the effects of Poly(ADP-ribose) polymerase(PARP) on necrosis in neuronal cells that have undergone needle electrode electrical stimulation(NEES) prior to induction of ischemia. Ischemia was induced in male SD rats(body weight 300g) by occlusion of the common carotid artery for 5 min, after which the blood was reperfused. After induction of brain ischemia, NEES was applied to Zusanli(ST 36), at 12, 24 and 48 hours. Protein expression was investigated using immuno-reactive cells, which react to PARP antibodies in cerebral nerve cells, and Western blotting. The results were as follows: In the cerebral cortex, the number of PARP reactive cells after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. PARP expression after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. As a result, NEES showed the greatest effect on necrosis- related PARP immuno-reactive cells 24 hours after ischemia, indicating necrosis inhibition, blocking of neural cell death, and protection of neural cells. Based on the results of this study, NEES can be an effective method of treating dysfunction and improving function of neuronal cells in brain damage caused by ischemia.

Background: Mahonia Nepalensis DC. (Hoang lien o ro), the specie of the family Berberidaceae, is widely distributed in the high mountainous areas at altitudes 1700 – 1900 m of Vietnam. It is found that the stem of Mahonia nepalensis indicated anti-inflammatory, anti-bacterial and antifungal activities and they are used particularly for the treatment of eczema, psoriasis, and other skin conditions. However, no study on the antioxidant and anti-cancer activities of Mahonia Nepalensis stem has been previously reported. The aim of this study was to evaluate anti-oxidant and anti-cancer activities of Mahonia Nepalensis stem. Methods and Results: The stem pieces of Mahonia Nepalensis were dried and extracted three times with 100% methanol. After that, the extract was suspended in distilled water and then partitioned with n-hexane, ethyl-acetate (EtOAc) and butanol (water saturated BuOH) fractions were then evaporated using a vacuum rotary evaporator. Evaluation of the anti-oxidative activity of Mahonia Nepalensis was carried out using a DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-producing system. The results revealed that the ethyl acetate fraction of M. nepalensis possessed higher potential DPPH radical scavenging activity (IC50, 81.88 ± 1.33㎍/㎖) than other fractions as well as BHT (2,6-Di-tert-Butyl-4-methylphenol) (IC50, 250.49 ± 1.60㎍/㎖). The reducing power assay was also investigated and EtOAc fraction showed higher absorbance values than other fractions. At 1.0 mg/ml concentration, EtOAc fraction showed absorbance of 1.72, be higher than Ascorbic acid. Cell viability was evaluated according to the MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyl tetrazolium Bromide) assay. By MTT assay, all fractions showed a significant reduction in cell viability on COLO 205 (Human colon carcinoma cell) at the highest concentration tested (200㎍/ ㎖) with over 70% decrease in cell viability was obtained, and the highest significantly inhibiting effect occurred in butanol fraction with approximately 90% reduction in cell viability. Conclusion: We demonstrated that Mahonia Nepalensis stem extract has highly potential in anti-cancer activity. Further studies are necessary in order to explore the variety of Mahonia Nepalensis stem to be applied as a valuable natural material.

Background : Haskap berries commonly refer to fruits of Lonicera caerulea L., recognized by the Japanese aborigines as the “The elixir of life.”. Due to their recent arrival on the North American market, haskap berries have not yet been positioned among other berries and compared in terms of their phytochemical content. And haskap berries have higher ascorbic acid and anthocyanin content than other berries known for their health-promoting benefits, such as blueberries. However, no study has reported on the antioxidant and anti-cancer activity of Lonicera caerulea stem. The purpose of this study is to present the current research on the chemical content, antioxidant and anti-cancer activities of Lonicera caerulea stem. Methods and Results : The stem of Lonicera caerulea L. ware dried in the shade at room temperature and extracted with 100% methanol. The extract was suspended in deionized water and partitioned sequentially with n-hexane, chloroform, ethyl-acetate and butanol (water saturated BuOH) fractions. Antioxidant activities were measured by determination of antioxidants, DPPH (2,2-diphenyl-1-picrylhydrazyl). Cell viability was determined by the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide] assay. All cell lines were purchased from the Korean Cell Line Bank (Seoul, Korea). All results were performed with three replications were processed statistically. By DPPH assay, the Lonicera caerulea L. the highest activity was obtained from the ethyl-acetate fraction (IC50=15.46 ㎍/㎖). By MTT assay, the chloroform fraction showed a significant growth inhibiting effect on MCF-7 (Human breast cancer, IC50=225.91 ㎍/㎖), COLO 205 (Human colon cancer, IC50=179.55 ㎍/㎖), but on AGS (Human stomach cancer) and other fractions it did not show effect. Conclusion : We demonstrated that Lonicera caerulea L. stem extract and fractions has antioxidant and antiproliferation activity in vitro. Further studies should identify the active constituents in Lonicera caerulea L stem to evaluate the potential in vitro antioxidant and antiproliferation activities of the extract.
