Background: The superficial lymphatic system is divided into areas called lymphatic territories which are separated by watersheds. When the lymphatic system fails to remove its load either due to surgery, radiotherapy or some congenital malformation of it then the fluid and the proteins and wastes contained within it accumulates in that territory. Anastomotic connections exist across the watersheds and while they can work unaided manual lymph drainage (MLD) can significantly help drainage across them into unaffected lymphatic territories. The purpose of the study is to examine the effectiveness of a manual technique in moving fluids and softening hardened tissues using a tape measure and Patient-Specific Functional Scale. Methods: We examined the movement of fluids from the affected limbs of lymphedema patients who underwent a standardized 30-min treatment using the Dr. Vodder method of MLD. We chose a typical cross section of patients with secondary leg or secondary arm lymphedema. The lymphedema patient was also measured after the conclusion of treatment and underwent a follow-up control measurement, within 8 weeks. Both evaluation tools indicated a movement of fluid to different and unblocked lymphatic territories as well as a softening of tissues in some of the affected limbs. Results: MLD is an effective means of fluid clearance when it accumulates as a consequence of a failure of the lymphatic system. It seems likely that MLD has a systemic effect on the lymphatic system and that it can improve flow from otherwise normal tissues. Conclusions: It is hypothesized that a series of treatments would result in even more significant improvements.

Purpose: Headache is a very common disease experienced at least once in daily life, and tension-type headaches have a high and increasing prevalence. Chronic headaches can cause functional damage and huge socioeconomic impacts. This study aimed to compare the effects of myofascial release technique with manual therapy and self-myofascial release technique using a foam roller on the pain threshold and body schema in patients with chronic tension-type headaches. Methods: The study was conducted on 20 patients living in Busan with chronic tension headaches. Myofascial release technique with manual therapy was performed on the suboccipital, sternocleidomastoid, scalene, and upper trapezius muscles. The self -myofascial release technique using a foam roller was applied to the cervical and thoracic muscles. A laterality test was performed using a recognized neck application developed to evaluate body schema ability. A pressure-pain threshold test was performed using an electronic pressure algometer to compare the results before and after the myofascial release technique. Results: After applying myofascial release with manual therapy and a foam roller, the pressure-pain threshold values showed significant changes in both groups (p<.05). As a result of the laterality test, myofascial release with manual therapy and a foam roller were applied to the painful area. The values showed significant changes in both groups (p<.05), but only the group using the foam roller showed a significant difference (p<.05) in painless areas. Conclusion: The myofascial release technique with manual therapy can be the primary treatment technique for pain control in painful areas. The self-muscle release technique using a foam roller can be an effective method when there is no pain or when maintenance is needed after pain control.

In many case, reinforced concrete structures are deteriorated by construction errors, design errors, settlement and movement, and weathering. The diagnose and repair of concrete deterioration is important for effective management of concrete structures. This manual is to provides guideline on evaluating the deterioration of the concrete in a structure and selecting an appropriate repair material and method.

This study deals with the method of test for waterproof agent and admixture of cement, and especially, the effect on bond strength between waterproofing layer and mortar or concrete substrate in building construction. Quality of that has been managed according to it of construction standard manual, housing construction manual, 건, and Q until performance of that is specified by law as KS F 4923. Therefore this study focus on the quality and trend for a fatty system and PCM(Polymer Cement Mortar)

It is difficult to obtain a swinging-up control sequence of a one-link pendulum analytically or numerically. In this paper, we obtain a proper control sequence through manual control experiments. However, no proper control sequence will be obtained if the rotational velocity of the pendulum is fast for the human operator. To overcome such a disadvantage, we propose a method for training the operator by using a pendulum simulator.

Port structures are one of the important infrastructure of the nation. To ensure safety and extend lifetime of the existing port structures, it is necessary to develop proper maintenance program. In this study, port inspection manual for pier type structure are developed. The flow of inspection program is designed and defect type for each component of wharf is classified. Also systematic method of rating and evaluation is developed together with conceptual design of port maintenance data base system.

Purpose : To assess the effect of applying an automated heart model based measurements of left ventricle (LV) and compare with manual and semi-automated measurements at Cardiovascular MR Imaging. Materials and Methods: Sixty-two patients who underwent cardiac 1.5T MR imaging were included. Steady state free precession cine images of 20 phases per cardiac cycle were obtained in short axis views and both 2-chamber and 4-chamber views. Epicardial and endocardial contours were drawn in manual, automated, and semi-automated ways. Based on these acquired contour sets, the end-diastolic (ED) and end-systolic (ES) volumes, ejection fraction (EF), systolic volume (SV) and LV mass were calculated and compared. Results: In EDV and ESV, the differences among three measurement methods were not statistically significant (P = .399 and .145, respectively). However, in EF, SV, and LV mass, the differences were statistically significant (P=.001, <001, <001, respectively) and the measured value from automated method tend to be consistently higher than the values from other two methods. Conclusion: An automatic heart model-based method grossly overestimate EF, SV and LV mass compared with manual or semi-automated methods. Even though the method saves a considerable amount of efforts, further manual adjustment should be considered in critical clinical cases.

Consumers turn away their face from a vehicle that doesn't satisfy their sensibility and is designed without consideration of driver's performance. In terms of driver's performance, the manual motor processor carries out the primary interactions between driver and vehicle. Therefore, in this paper, time prediction model is studied that is an important part when drivers manipulate the manual control during driving. Experiments were executed for 20 subjects using two kinds of vehicles and regressed to Fitts' Law. The noise filtering method was suggested for the performance times of manipulating the manual control. Especially, it was shown that Fitts' Law derived by an approximation of Shannon's theorem can predict drivers performance time more appropriately than other methods.

The platform screen door(PSD) hasn't been installed yet within the manual operation system, that is, ATS & ATC Signal system. In other countries, it is mostly installed and operated within automatic operation system, that is, ATO. Especially, as a part of the environment friendly system installation, the installation of PSD shall be considered aggressively to improve the air quality in the underground area and to maintain the air-conditioning. Besides the number of suicides in the subway station gets increased these days causing safety hazard, so the installation of PSD is positively reviewed. To install PSD in the manual operation system, it is important to stop the train at the correct position. So we would like to suggest the technical system thereby.
