Objectives: We investigated muscle force from the upper limb lifting resistance test to conform the objectivity in manual muscle test. Methods: We made standard method in upper limb lifting resistance test to compare with experiment method switching the lower limb position left & right. And resistance forces of upper limb of subject were checked to inspector with closing eyes. Results: 1. The lifting resistance of right upper limb was stronger when the lower limb of right and left were abducted. 2. The lifting resistance of right upper limb was weaken when the lower limb of right and left were adducted. 3. The lifting resistance of right upper limb was weaken when the lower limb of right and left were elevated. Conclusions: As the above results, the deltoid muscle force checked in the upper limb lifting resistance test is affected by the location of lower limbs, it suggested that the muscle force of some part in the body will be affected by the other parts. It will be useful to understand the symmetry principle of body in muscle function.

만성 요통 환자들에 대한 다양한 치료적 중재 방법이 있다. 그러나 대부분의 치료들이 통증에 대한 치료들이다. 만성 요통 환자들은 요추관절들의 구조적 고착들을 가지고 있다, 이러한 구조적 고착들은 관절가동범위을 저하시키고 나아가 동적 균형능력의 저하를 발생시킨다. 동적 균형능력의 저하는 손상을 가중시키고 위험상황에서의 대처능력을 감소시킨다. 따라서 본 연구에서는 만성요통환자들에 대한 즉각적인 동적 균형능력의 회복을 위하여 메이트란드의 도수치료의 방법들을 이용하였다. 만성 요통 환자 64명을 대상으로 메이트란드의 도수치료를 적용한 실험군 32명, 이학적 도구(온열팩, 저주파치료기, 초음파)를 사용한 대조군 32명을 대상으로 하였다. 각 군의 치료 전, 후의 동적 균형능력을 비교하기위하여 신뢰도가 높은 스타 익스커션 밸런스 테스트(0.81-0.96)를 이용하였다. 실험군에서 치료 후 동적 균형능력이 전방, 오른쪽, 왼쪽, 후방모두에서 증가하였고 대조군에서는 변화가 없었다. 따라서 메이트란드의 도수치료가 만성요통환자들의 요추 관절을 유연하게 해서 즉각적인 동적 균형능력을 증가시키는데 영향을 주었다고 생각된다.

Background: The elderly are likely to fall due to physical and mental atrophies, and experiencing falls may result in fear of falls and lack of self-confidence, which also leads to hesitation to physical activities and changes in walk and balance, the major variables in independent daily life. Methods: In three senior citizen centers located in D city, 22 elderly women aged 65 or older were chosen, and they filled in the questionnaire which included their agreement to voluntarily participate in the survey and medical histories. As to whether they had falls experience, the medical history items in the questionnaire asked them if they had falling down or falls once a year, twice for the three years. The objects were divided to NFE (non-falls experience) and FE (falls experience). Results: 1. As to walking abilities, significant difference was found between NFE and FE regarding walk width, stepping with two feet, and stride length while there was no significant different in terms of cadence. 2. As to balancing abilities, was significant difference between NFE and FE in terms of the physical body center area. As to the sit-to-stand, tandom gait test, no significant difference was found, and neither in the timed up and go test. Conclusions: The elderly with falls experience has inferior walking and balancing abilities to those without falls experience, and thus they are more exposed to the risks of falls.

Background: The purpose of this study was to compare the effects of mulligan taping on knee joints on balance ability and strength with repeated measurements. Methods: Seventeen patients were randomly assigned to the 8 taping group and the 9 repeat measurement group. To measure the balance ability, fall risk assessment equipment was used, and the measurement of the muscle strength was performed by using the equipment of the same company. Results: Balanced abilities and muscle strength were increased in groups with taping only after Mulligan taping. Conclusions: The application of mulligan taping did not have the effect of stimulating the inherent receptive sensation. However, active grouping of the knee joint taping only, and muscle strength and muscle strength were increased. It increases the stability and activity of the muscles that operate on the balance of the active knee joint and muscle strength, thereby enhancing exercise prevention and prevention performance and exercise performance.

Objectives : The purpose of this study was to assess the use of Korean medicine for treating radial nerve palsy. Methods : We searched for studies on the use of Korean medicine for the treatment of radial nerve palsy in 7 electronic databases and analyzed these studies. Results : We found 95 studies on radial nerve palsy from 7 electronic databases. We excluded 77 duplicate studies, 1 review article and 2 studies published before 2000. As a result, 15 case studies(36 patients) were included. Acupuncture(15 times), electroacupuncture(6 times), pharmacopuncture(9 times), herbal medicine(11 times), physical therapy(10 times), moxibustion(3 times), cupping therapy(1 time), chuna manual therapy(1 time) and yinyang balancing appliance(1 time) were used. LI11 for acupuncture, LI4, LI11 for electroacupuncture, bee venom as pharmacopuncture material and LI4, LI10, LI11 in pharmacopuncture point, Boik-tang gami as herbal medicine, hot pack for physical therapy, LI4, LI11 for moxibustion were the most frequently used. Conclusions : Korean medicine treatment for radial nerve palsy has been performed in various ways. However, we found limited evidence regarding Korean medicine for radial nerve palsy. Thus, we think various types of studies including more case reports, for radial nerve palsy should be performed in the future.

The cooling water system for the PEFP 20 MeV proton accelerator was established and tested to obtain the precise resonance frequency of DTL through the temperature control of cooling water. The water temperature in the main flow loop was manipulated by adjusting the proportion of hot water returning from the DTL structures through the heat exchanger loop. Due to low duty factor operation and insufficient cooling loop installation of the DTL tanks, the manual mode operation was applied to maintain the DTL temperatures close to their resonance temperatures. The optimized process conditions with flow balancing and pressure drop in the DTL cooling systems are reported.

To prevent an insulator failure, an automatic cleaning robot was developed for suspension insulator strings. The robot autonomously moves along the insulator string using the clamps installed on its two moving frames, and adopts a dry cleaning method using rotating brushes and a circular motion guide. In addition, a mechanized brush bristles and a voltage-balancing contactor are devised to increase cleaning efficiency and to prevent arc generation under live-line conditions, respectively. Moreover, a manual tool for its installation and removal is presented. We confirmed its effectiveness through experiments.

Background: The purpose of this study was to examine the effect of transcranial direct current stimulation (tDCS) on the pain and balance of patients who receive total knee arthroplasty (TKA). Methods: This study subjects were 24 patients in Hospital T, located in Daegu, South Korea who received TKA after being diagnosed with degenerative arthritis. The subjects were randomly divided into and experimental group and a control group, with each group including 12 patients. Both group received superfical thermal therapy, interferential current therapy (ICT), and continue passive motion (CPM), which are conventional knee therapy on the knee joint. The experimental group received the tDCS treatment three times a week for three weeks, from October 1st to October 20th. The visual analogue scale and Wii Balance Board system were used to measure the pain and balancing ability, respectively, of both groups. In the statistical result analysis, to compare about pre and post test difference in each groups was accomplished. Statistical analysis of independent t-test and paired t-test were conducted using SPSS version 23.0. Results: After three weeks of intervation, there were significantly difference in balance ability in pre and post test in the tDCS group. VAS decreased significantly in both groups(p<.05), There was a significantly difference in pain, balance ability in the tDCS group compared to the sham group. Conclusion: These results indicate that applying tDCS together with conventional knee joint therapy for TKA patients is effective in promoting the patients' recovery.

Recently, with the remarkable increase of social network services, it is necessary to extract interesting information from lots of data about various individual opinions and preferences on SNS(Social Network Service). The sentiment information can be applied to various fields of society such as politics, public opinions, economics, personal services and entertainments. To extract sentiment information, it is necessary to use processing techniques that store a large amount of SNS data, extract meaningful data from them, and search the sentiment information. This paper proposes an efficient method to extract sentiment information from various unstructured big data on social networks using HDFS(Hadoop Distributed File System) platform and MapReduce functions. In experiments, the proposed method collects and stacks data steadily as the number of data is increased. When the proposed functions are applied to sentiment analysis, the system keeps load balancing and the analysis results are very close to the results of manual work.

This research attempted to find possibilities of the practical use utilizing geospatial methods for the balanced promotion of sustainable coastal development and preservation through a case study of Jekyll Island, one of Georgia's barrier islands. In response, this research provided ways for practical use in sustainable development and preservation plans. First this research thoroughly investigated the 1996 master plan of Jekyll Island and tried to recalculate developed and undeveloped areas. Second, new estimations for developed areas were investigated through field survey. Third, this research proposed the use of the satellite images with different levels of spatial resolutions and tested different classification schemes to find possibilities for practical use. For these purposes, first, we classified developed and undeveloped features by manual digitization using an aerial photo image with 0.5m spatial resolution. Second, a Landsat 7 ETM+ and a QuickBird satellite images with mid- and high-levels of spatial resolutions were applied to identify developed and undeveloped areas using both the National Land Cover Data (NLCD) and the Coastal Change Analysis Program (CCAP) classification schemes. Also, GEOBIA (Geographic Object-Based Image Analysis) was conducted to accurately identify developed and undeveloped areas.
