The effect of non-point source pollution in rural area has much influence on the stream water quality. It is difficult to improve the stream water quality, because of complex pollutant loads technically and because of treatment-cost of the deteriorated water economically. The best way to reduce the non-point source pollution is to check the water quality in the inlet of irrigation channel and control the water quality in the outlet of drainage channel. Stream water quality in the rural area is closely related with the fertilizers, pesticides, and livestock wastewater. Basically the rate of treatment and retention time were estimated for BOD, COD, SS, NH₄-N, T-N, NO₃-N, T-P, PO₄-P using materials such as gravel, crushed stone, useless tire, geotextiles, and concrete block, respectively and also using the combined materials. The rate of treatment for BOD, COD, SS is high, but that for NH₄-N, T-N, NO₃-N, T-P, PO₄-P is low. Optimal retention time in the natural contact channel was 90 minutes.

Objective: This study aimed to determine the effect of proprioceptive neuromuscular facilitation (PNF) balance exercise on the ability to balance and walk in patients with hemiplegia caused by stroke. Design: A randomized controlled trialMethods: Following baseline measurements, patients (n=24) with hemiplegia caused by stroke were randomized into two groups: the PNF balance group (n=12) that received PNF balance exercise and the balance group (n=12) that received general balance exercise. Each group joined the intervention for 30 minutes, 5 times per week for 6 weeks. Both groups performed the Timed Up and Go test (TUG) and Berg Balance Scale (BBS) for balance, as well as the 10-meter walking test (10MWT) and 6-minute walk test (6MWT) for walking. The data were collected both before and after the intervention. The paired t-test was used to compare the post-intervention changes compared with pre-intervention data. An independent t-test was used to analyze the differences in the dependent variables between the two groups. Results: After the 6-week intervention, both groups showed significant improvements in balance (TUG, BBS) and walking (10MWT, 6MWT) parameters (p<0.05). The patients in the PNF balance group showed greater improvements in balance (TUG, BBS) and walking (10MWT, 6MWT) than those in the balance group (p<0.05). Conclusions: PNF balance exercise shows improvements in balance and walking parameters in patients with hemiplegia caused by stroke.

Dual biocontrol of both insects and plant pathogens has been reported for certain fungal entomopathogens, including Beauveria bassiana and Lecanicillum spp. In this study, we demonstrate, for the first time, the dual biocontrol potential of two fungal isolates identified by morphological and phylogenetic analyses as Isaria javanica. Both these isolates caused mortality in the greater wax moth, and hence can be considered entomopathogens. Spores of the isolates were also pathogenic to nymphs of the green peach aphid (Myzus persicae), with an LC<sub>50</sub> value of 10<sup>7</sup> spores/mL 4 days after inoculation and an LT<sub>50</sub> of 4.2 days with a dose of 10<sup>8</sup> spores/mL. In vitro antifungal assays also demonstrated a strong inhibitory effect on the growth of two fungi that are pathogenic to peppers, Colletotrichum gloeosporioides and Phytophthora capsici. These results indicate that I. javanica isolates could be used as novel biocontrol agents for the simultaneous control of aphids and fungal diseases, such as anthracnose and Phytophthora blight, in an integrated pest management framework for red pepper.

Objective: We aimed to investigate differences of range of motion in measuring shoulder internal rotation (IR) and external rotation (ER) resulting from posture change in manual scapular stabilization in prone, hook-lying, sitting, and standing positions in healthy young adults. Design: Cross-sectional study. Methods: This study included healthy young adults who agreed to participate after a thorough explanation about the study purpose and methods. A clinometer was used to measure shoulder rotation. Measurements of shoulder rotation according to postural change were performed in prone, hook-lying, sitting, and standing positions. The repeated measures analysis of variance was used to compare between-group differences in postural change. Results: The lower the posture, the greater the average value of IR angle. In contrast, the higher the posture, the greater the average value of the external rotation angle. In active and passive IR with posture change, there was difference in average value but with no statistical significance. In active and passive ER, there was a statistically significant difference between prone and sitting, prone and standing, hook-lying and sitting, hook-lying and standing, and sitting and standing position (p<0.05). Conclusions: Our findings suggest that postural change should be considered in order to increase the strength or range of motion of the internal and external rotation of the patient's shoulder joint.

Objective: This study is a systematic review conducted to analyze the environmental factors that cause falls in the older adult. Design: Systematic reviewMethods: The study was conducted by searching the Research Information Sharing Service (RISS), Korean studies Information Service System (KISS), and Data Base Periodical Information Academic (DBpia) databases for literature published in South Korea up to July 2020. A total of 12 studies were selected for analysis based on the inclusion and exclusion criteria. Results: The results of the analysis revealed that all the selected literature were surveys and the study subjects were 65 years of age and above. The sample size ranged from a minimum of 95 subjects to a maximum of 3,278. A total of eight tools were used to measure the environmental factors associated with falls. The prevalence and recurrence of falls increase with age and deterioration of health. Older adult individuals who experience falls encounter difficulties in recovering from impaired physical function and disability; moreover, in severe cases, falls may lead to death. Falls are largely associated with a combination of intrinsic and extrinsic (i.e., environmental) factors. The purpose of this study was to assess potential extrinsic risk factors for falls. Falls occur in indoor environments, such as washrooms, bathrooms and living rooms, and outdoor environments, including roads and stairways, depending on the season, time of day, and use of ambulatory aids. In such environments, falls are mainly caused by slipping and stuttering. Conclusions: Therefore, as the rate of fall is influenced by several factors, extrinsic factors should be improved by developing comprehensive accident prevention programs that address the improvement of environmental risk factors around places of residence to reduce risk factors among the older adult, who, especially, are at a high risk for falls.
A Systematic Review of Elastic Taping Effect of Patients with Stroke
( Beom-ryong Kim ),( Tae-woo Kang ) 대한물리치료학회 2018 대한물리치료학회지 Vol.30 No.4
This study was conducted to evaluate the effectiveness of taping intervention in patients with stroke through a review analysis of taping interventions used to enhance physical function and activity in patients with stroke. We searched randomized controlled trials using electronic databases. We also manually reviewed sources to identify additional relevant studies. Taping intervention is an approach to treat individuals with impaired physical function and activity. Taping interventions affect body functions by providing increased muscle strength, proprioceptive sensation, and range of motion, as well as decreased rigidity and pain. Taping interventions also improve walking, balance and arm functions, such as physical activity. Taping intervention for patients with stroke has been shown to be highly effective and is therefore strongly recommended; however, it is suggested that it be further developed to improve its efficacy as an intervention method and to create additional taping methods.

Purpose: This study aimed to demonstrate reduction in stroke symptoms by analyzing the changes in respiratory function and activities of daily living (ADL) after respiratory muscle strengthening exercise in patients who had a stroke and thereby, propose an efficient exercise method. Methods: Twenty patients with hemiplegic stroke were divided into two groups, with 10 patients in each. The control group (CG) received the traditional exercise therapy, and the experimental group (EG) received the traditional exercise therapy combined with expiratory muscle strengthening training. The training continued for 6 weeks, 5 days a week. Forced vital capacity (FVC) and forced expiratory volume at 1 second (FEV1) were measured with a spirometer, SpO<sub>2</sub> was measured with a pulse oximeter, and ADL were assessed by using the modified Barthel index (MBI). A paired t test was applied to compare the differences before and after the intervention, and an independent t test was used to compare the differences between the groups. The level of statistical significance was set as α=0.05. Results: The changes in the FVC and FEV1 values within the group showed significant differences only in the EG (p<0.01). The between-group difference was statistically significant only for FVC and FEV1 in the EG (p<0.01). The changes in SpO<sub>2</sub> and MBI within the group showed significant differences only in the EG and CG (p<0.01). Between-group differences were statistically significant only for SpO<sub>2</sub> and MBI in the EG (p<0.05). Conclusion: The interventions with active patient involvement and combined breathing exercises had a positive impact on all the functions investigated in this study.
