The purpose of this case report is to investigate whether an attempt to hold the repeated upright posture under blocking the patient's vision affects the deficits to push away from the paralytic side and the relapse time from down to stand up position without push away in patients with hemiplegia with pusher syndrome. Two hemiplegic patients with pusher syndrome were assessed. The task was performed 4 times per day for 6 weeks. The modified barthel index (MBI) was performed to assess activities of daily living (ADL). For assessing balance, the "balanced sitting" and "sit to stand" are analyzed using by modified motor assessment scale (MMAS). The scale for contraversive pushing (SCP) was used for determination of push away from paralyzed side. MBI, MMAS and SCP were assessed before and after trial of the task. In patient 1, total score of the scale is 0 in sitting posture and standing posture within 3 weeks and 4 weeks, respectively, In patient 2, total score of the scale is 0 in sitting posture and standing posture within 4 weeks and 6 weeks, respectively. These results demonstrated that pusher syndrome was completely resolved in at least 6 weeks. Our findings indicate that this physical therapy seems to be relevant for the hemiplegic patients with pusher syndrome.

This paper presents an experimental study of a newly developed composite floor system, built up from thin-walled C-profiles and upper concrete deck. Trapezoidal sheeting provides the formwork and the fastening of the sheet transmits the shear forces between the C-profiles and the deck. The modified formation of the standard self-drilling screw in the beam-to-sheet connection is applied as shear connector. Push-out tests are completed to study the composite behaviour of the different connection arrangements. On the basis of the test results the behaviour is characterized by the observed failure modes. The design values of the connection stiffness and strength are calculated by the recommendation of Eurocode 4. In the next phase of the experimental study six full-scale composite beams are tested. The global geometry is based on the proposed geometry of the developed floor system. The applied shear connections are selected as the most efficient arrangements obtained from the push-out tests. The experimental behaviour of the composite beams are discussed and evaluated. As a conclusion of the experimental study the Eurocode 4 plastic design method is validated for the developed composite floor.

This research aims to conduct a pilot study for the in-fire performance of headed studs, commonly used in composite structures over the world. The robustness of the shear studs in fire appears to be a key element to govern the composite behaviour after a sudden local instability developed in structures such as trusses and cellular beams. In order to experimentally evaluate the residual strength of studs in fire, the standard push-out test was modified for a half of the original set-up to be equipped with a furnace. The adjustments allow the steel section to have a 3-sided exposure against fire. Under the Standard ISO fire, the modified push-out tests under loading were conducted to identify the failure mechanism of the studs in relation to temperature developments.

This paper presents a cascaded coil flux control based on a Current Source Parallel Resonant Push-Pull Inverter (CSPRPI) for Induction Heating (IH) applications. The most important problems associated with current source parallel resonant inverters are start-up problems and the variable response of IH systems under load variations. This paper proposes a simple cascaded control method to increase an IH system's robustness to load variations. The proposed IH has been analyzed in both the steady state and the transient state. Based on this method, the resonant frequency is tracked using Phase Locked Loop (PLL) circuits using a Multiplier Phase Detector (MPD) to achieve ZVS under the transient condition. A laboratory prototype was built with an operating frequency of 57-59 kHz and a rated power of 300 W. Simulation and experimental results verify the validity of the proposed power control method and the PLL dynamics.

The purpose of this study was to examine the convergence correlation between physical characteristics and functional movement screen(FMS). Overall, 193 adults with normal single measurement values participated in the study. For data analysis, we used the SPSS Ver. 26.0 statistical program to perform t-tests and to determine Pearson's correlation coefficients for variables. Data analysis revealed significant sex differences in the active straight-leg raise and trunk stability push up tests (P<.05). In addition, our data analysis also revealed a negatively correlation between body fat percentage and FMS tests, except in the shoulder mobility and active straight leg raise test. In the active straight leg raise, the quality of functional movement was higher in women than in men; while in the trunk stability push ups, the quality of functional movement was higher in men than in women. Therefore, we conclude that men should reinforce the flexibility of the lower extremities, and females should apply upper body muscular strength for better trunk stability movement.

Objectives: The development of internet programs for smoking cessation was motivated to quit smoking in the large group of smokers. This personalized program consisted of tailored message to consider the smokers characteristics, and contain the informations on the outcomes of smoking cessation and the skills to be used in the quit attempts. The purpose of this study was to develop the internet management program and information push-delivery system for smoking cessation to encourage the personal intention to quit smoking. Methods: We conducted in 3 steps as developing push service to encourage intention of smoking cessation, analyzing problems of smoking cessation program through the pilot test and suggesting improvements by implication stages. Results: This program is delivered for 30 days. if the participants do not fail to quit smoking. The contents consisted of 13 stages which were divided on starting period. practical period, maintenance period and success period. And push service afforded the tailored message to participants using their e-mail. According to the evaluation of pilot test, the problems of internet information push-delivery service for smoking cessation were the over-tasks per visiting time, recording style of participants, difficulty of terms and sentences, lack of visual effects, absence of follow-up module and unsuitable link with main homepage. Improvements were divided on 3 stages by implication period. The first stage included the immediate improvements as improving link with homepage, modifying menu of smoking information and upload file of notice part. The second stage included the short term improvements as alleviating condition of withdrawal, coordinating start stage of retrial, modifying errors of information push-delivery service and addition of educational materials. The third stage included the long term improvements as development of follow-up module, cost-effectiveness evaluation, reducing contents quantity, introduction of checking style, compensation of graphics effect and review for SMS utilization. Conclusions: This program contribute to improving smoking cessation rate. Therefore this program should be tested in a community to evaluate the effectiveness. To promote the effectiveness, this program should be developed the contents and the strategies for various targets, and established the follow-up system for ex-smokers.

In general, there are various types of boost converters such as Boost converters, Buck-Boost converters, Flyback converters, Push-Pull converters, etc. Among them, Boost converters are the most widely used and step up converters in a very simple form. However, Boost converter has DCM mode operation, big ripple problem and RHPZ problem. In order to solve these problems, a converter to which the new topology was applied was presented, but among them, the KY converter improved the Boost converter's DCM mode operation, the big ripple problem and the RHPZ problem. However, the conventional KY converter has a drawback that the voltage gain is relatively lower than that of the Boost converter. Therefore, in this paper, we proposed a new KY converter that solves the problem of low voltage gain while having the advantages of the conventional KY converter.

Today the web-based learning management information systems are developed as forms of many ordered learning information systems acting up to the personal characteristics, but the previous systems have difficulty in their mutual working, maintaining, and repairing between the systems, because of their one-sided "push" method or reuse of the contents. Also they were not managed together having the dissimilar learning management systems each. Therefore, I made up for the weak points of the previous systems and embodied the international standard SCORM-based ordered learning management information systems. After adapting to sequencing contents, all systems are supplied; giving lectures, solving the problems, evaluating the learners and the function of successive personalization learning based on the result of the learner evaluation systems.
