Recently, it has been increased disaster of crops and agricultural facilities with climate change such as regional storm, typhoon. However agricultural facilities have unsafe design criteria of improving drainage corresponding to this change. This study has analyzed the impact that inundation area and magnitude of drainage-facility is decided based on fixed- and unfixed-duration precipitation by applying revised design criteria of drainage for climate change. The result was shown that 1-day and 2-days rainfall for 20-years return period has increased about 11.4%, 4.4% respectively by changing fixed- to unfixed duration. And the increase rate of design flood was 15.0%. The result was also shown that Inundation area was enlarged by 6.6% as well as increased inundation duration under same basic condition in designed rainfall between fixed- and unfixed-duration. According to the analysis, it is necessary for pump capacity in unfixed-duration to be increased by 70% for same effect with fixed-duration. Therefore, when computing method of probability precipitation is changed from fixed one to unfixed-duration by applying revised design criteria, there seems to be improving effect in drainage design. Because 1440-minutes rainfall for 20-years return period with unfixed-duration is more effective than 1-day rainfall for 30-years return period with fixed-duration. By applying unfixed-duration rainfall, capacity of drainage facilities need to be expanded to achieve the same effects (Inundation depth & duration) with fixed-duration rainfall. Further study is required for considering each condition of climate, topography and drainage by applying revised design criteria.

Background: The advantages of robotic therapy have recently been attempted several times in the rehabilitation of total hip arthroplasty (THA) patients. Therefore, this study also aims to report a case of how robot therapy affects the function of THA patients due to developmental dysplasia of the hip (DDH). Design: Case Study. Method: This study used the A-B-A' design. Period A is before robotic therapy, period B is robotic therapy, and period A' is after robotic therapy. The subjects performed physical therapy and occupational therapy for five days each during the baseline period A and A'. In intervention period B, robotic therapy was performed for five days along with the baseline intervention. This study was conducted for a total of fifteen days. The subjects' sit to stand (STS), timed up and go (TUG), and 10 metre walk (10MW) were evaluated. Result:: STS and TUG were significantly improved in periods B and A' compared to period A (p<0.05), and STS was significantly improved in period A' compared to period B (p<0.05). 10MW showed no significant improvement in periods B and A' compared to period A. Conclusions: This study confirmed that robot therapy was an effective intervention in improving the function of women in their 30s who underwent THA due to DDH. In the future, a study comparing the control group should be performed.

This paper studied the present condition of social welfare activities of Living Condition Improving Committee of Kimpo City in order to activate the social welfare services of women agricultural organizations. The main results are as follows; First, the general characteristics of the respondents in this study are forty or fifty years of age with above high school education with main income source of agriculture and middle class women living in agricultural communities more than 10 years. Second, considering the present and future planned activities of the Living Condition Improving Committee of Kimpo City this study finds that there is high expectation of helping poor people and joining voluntary services. Third, the members of the Living Condition Improving Committee of Kimpo City have actively participated in the local welfare service programs however, there is significant difference among people according to the age, living standard and joining period. Fourth, out of social welfare activities managed by the Living Condition Improving Committee of Kimpo City the welfare service activities for old people and local community are most active and the participants in the welfare service activities for women and the youngsters are small. Thus, according to this study the Living Condition Improving Committee of Kimpo City should consider the following three points in order to activate the social welfare service activities; First, as the members are expecting to expand the individual activities and to enhance the private improvement, the social welfare service activities should meet with the demands to improve self satisfaction of the participants. Second, new programs should be developed after reviewing the current programs in order to meet with the need of the members. Third, as the committee has not established a network system with government administrative organizations and relating institutions, and as its activities are concentrated in particular areas the committee should establish a new system to provide more efficient services in line with the cooperation with public organization and welfare resource suppliers.

Background : Treadmill training has been proposed as a useful adjunct to conventional physical therapy to restore ability to walk after stroke. The purpose of this study to inform clinical practise by evaluating the research evidence for the effectiveness of treadmill training after stroke. Methods : We searched to the effectiveness of any form of intervention for effect of treadmill training by Dankook University electronic library databases of Medline, Embase, Cinahl, Amed and PEDro combined with a hand search of papers published in relevant peer-reviewed journals. Any type of study relevant to the topic published in English during time period from 1980 to 2007 was included. Results : The literature search identified 35 studies. The included studies enrolled a total of 374 subjects. 1. Treadmill retraining without partial body weight support might be more effective than no treatment at improving gait velocity, get up and go time, gait endurance and step length symmetry. 2. Treadmill retraining with partial body weight support might be more effective than no treatment in improving step length symmetry, gait velocity, gait endurance and balance. 3. Treadmill retraining might be more effective with partial body weight support than without it at improving gait velocity and motor improvement as measured by The Stroke Rehabilitation Assessment of Movement(STREAM). 4. Treadmill retraining without partial body weight support may be no different from physiotherapy and increase gait velocity to conventional gait therapy. 5. Treadmill retraining with partial body weight support may be no different from physiotherapy for gait velocity, motor recovery and balance. Conclusion The review suggests that although treadmill training of gait, especially with partial body weight support, might Improve gait parameters and functional mobility, unless treadmill training is directed at Improving gait speed it might be no more effective than conventional physical therapy at improving gait parameters.

Objectives : This study was planned to help clinical treatment by examining the efficacy and frequency of use of medicines with removing nebula and improving vision action, centering on historical literature. Methods : Chinese literature centered on CNKI published after 2000 and ophthalmic books of the Beijing University of Chinese Medicine Library, regardless of the publication period. Domestic literature was searched using NDSL and OASIS, and literature published after 2000 was referenced. Results : According to traditional medical classics, as medicine with removing nebula and improving vision action, medicine with dispelling wind and clearing heat action accounted for the majority. However, it is desirable to use these medicine in the early stages of the disease. Conclusions : 1. Among the external contacts that induce corneal opacity, the wind-heat pattern was the most common. Among the visceral manifestation patterns that induce corneal opacity, liver or spleen was the most common. Cold-tempered medicine which is dispelling wind, clearing heat and bottling up the liver were most commonly used as therapeutic medicine. 2. As removing nebula and improving vision medicine, Cassiae Semen, Chrysanthmi Flos, Eriocauli Flos, and Buddlejae Flos have been widely used. 3. It has been investigated that removing nebula and improving vision medicine can be effectively used in the early stages of various diseases that cause corneal opacity.

Purpose: The purposes of this study were to examine muscle activities of trunk and lower limb during squat and 108 bows exercises and to provide objective data for establishing a training method for improving muscle strength of trunk and lower limb. Methods: Twenty normal healthy subjects participated in this study. Each exercise was divided into five periods. Muscle activities of trunk and lower limb in each period of both 108 bows and squat exercises were measured and analyzed by independent t-test. Results: In starting, mid-flexion, mid-extension, and end period muscle activities obtained from 108 bows exercise were significantly higher than those from squat exercise. However, in the final flexion period, muscle activities of multifidus, elector spinae, rectus femoris, biceps femoris, and tibialis anterior from squat exercise were significantly higher than those from bow exercise. Conclusion: In this study, high muscle activities in most muscles of trunk and lower limb were observed from all periods of 108 bows exercise except the final flexion period. Therefore, it is likely that 108 bows exercise rather than squat exercise is more suitable for high strength exercise to improve muscle strength of trunk and lower limb and thus will be applicable for strengthening muscles of trunk and lower limb of patients.

Efficient energy consumption in WSN is one of the key design issues for improving network stability period. In this paper, we propose a new Heterogeneity-aware Energy-efficient Clustering (HEC) technique which considers two types of heterogeneity - network lifetime and of sensor nodes. Selection of cluster head nodes is done based on the three network lifetime phases: only advanced nodes are allowed to become cluster heads in the initial phase; in the second active phase all nodes are allowed to participate in cluster head selection process with equal probability, and in the last dying out phase, clustering is relaxed by allowing direct transmission. Simulation-based performance analysis of the proposed technique as compared to other relevant techniques shows that HEC achieves longer stable region, improved throughput, and better energy dissipation owing to judicious consumption of additional energy of advanced nodes. On an average, the improvement observed for stability period over LEACH, SEP, FAIR and HEC- with SEP protocols is around 65%, 30%, 15% and 17% respectively. Further, the scalability of proposed technique is tested by varying the field size and number of sensing nodes. The results obtained are found to be quite optimistic. The impact of energy heterogeneity has also been assessed and it is found to improve the stability period though only upto a certain extent.

The study is conducted to evaluate loading of organic matter as seasonal changes during non-storm period into Lake Paldang which is used to a major drinking water source. Samples were taken in Lake Paldang intake during non-storm period and were analyzed loading of organic matter. From the results of the survey, improving of the water quality showed remarkable tendency depending on the changing periods from summer to fall and from fall to winter. Dilution effect from the increase of base run-off caused by the concentrated rainfall in rainy season, the characteristics of Korea's climate seems to have to be the reason. On the other hand, deteriorating of the water quality showed tendency depending on the changing periods from winter to spring and from spring to summer. Increase of Cyanobacteria etc. is explained by seasonal effects which are a small amount of the rainfall in winter and spring and gradational increase of water temperature.

Purpose: Recently, many studies on robotic rehabilitation have been conducted, but such studies on patients with ankle sprains are lacking. This study aimed to investigate the effects of robot-assisted rehabilitation on the range of motion of the ankle and balance in patients with ankle sprain. METHODS: This study used the A-B-A' design and was conducted for a total of fifteen days. The subjects performed general physical therapy for five days each, during the baseline A and A' periods. In period B, robot rehabilitation was performed for five days, along with general physical therapy. The subjects were evaluated based on weight-bearing lunge test (WBLT), single leg stance (SLS), and functional reach test (FRT). RESULTS: The WBLT, STS, and FRT showed significant improvement in periods B and A' compared to period A, but there was no significant improvement in period A' compared to period B. Conclusion: This study confirmed that robot-assisted rehabilitation was an effective intervention for improving the function of patients with ankle sprain. In the future, a study with a control group comparison should be performed.
