Objective: This study reports the effectiveness of the Korean medicine treatment of patients with intracerebral and intraventricular hemorrhages suffering unilateral neglect symptoms. Case presentation: The patient was treated using Korean medicine, including acupuncture, herbal medicine, moxibustion, and a limb activation exercise. We measured Unilateral Neglect Symptom progress with a numeric rating scale, Albert's test, Line bisection test, Clock drawing test, and Catherine Bergego Scale. After eight days of combined Korean medicine and rehabilitation exercise, the Unilateral Neglect Symptom intensity reduced from NRS 8 to 6. In addition, Albert's test score decreased from 2.5% to 0%. The Line bisection test score decreased from 19 mm to 12 mm, and the Clock drawing test score improved from 8 to 10. Last, the Catherine Bergego Scale decreased from 12 to 9. No adverse events were observed during treatment. Conclusion: This study suggested that a complex treatment including Jaeumkunbi-tang, acupuncture, moxibustion, and limb activation exercise can be effective for an intracerebral hemorrhage with intraventricular hemorrhage patient suffering from Unilateral Neglect Symptoms. Consequently, more research is needed in the future.

this paper present an efficient line-drawing algorithm that reduces the amount of space required, Because of its efficiency , this line-drawing algorithm is faster than the Bresenham algorithm or the recursive bisection method. this efficiency was achieved through a new data structure; namely , the modified segment tree (MST). Using the modified segment tree and the distribution rule suggested in this paper, we dra lines without generating the recursive calls used in [3] and without creating the binary operation used in [4]. we also show that line accuracy improves in proportion to the display resolution . In practice, we can significantly improve the algorithm's performance with respect to time and space, This improvement offer an increase in speed, specially with lines at or near horizontal, diagonal. or vertical ; that is, this algorithm requires the time complexity of (n) and the space complexity O(2k+1), where n is the number of pixels and k is a level of the modified segment tree.

Thc chimeric morulae were produced following aggregation of the half embryos which were microsurgically bisected at 8-cell and early morula stage. Different phenotypic embryos were obtained by mating ICR female mice with ICR or CBA male mice. The early morula stage was thc desirable stage for the aggregation of mouse embryos after bisection. The post-thawed survival rates of bisected-aggregated embryos that developed into normal blastocyst after conventional freezing in DMSO and ethylene glycol were 30.5 and 32.896, respectively. One offspring was produced by transferring the 67 frozen-thawed bisected-aggregated embryos.

A fast estimation method using wavelet transform for a time delay system is proposed. Main point of this method is to get the wavelet transform of the correlation between the input signal and delayed signal using transformed signals. But wavelet transform using Haar wavelet functions has basis with different phases and can offers a bisection method to estimate a time delay of a signal. Selective computation of the transform of correlation is performed and the computational complexity is reduced. Computational order of this method is O(N log N) and it is much love. than a simple correlation esimation when the length of signal is long.

A reader usually spends a lot of time browsing and searching word meaning in a dictionary, internet or smart applications in order to find the unknown words. In this paper, we propose a method to compensate this drawback. The proposed method introduces a vocabulary upon recognizing a word or group of words that was captured by a smart phone camera. Through this proposed method, organizing and editing words that were captured by smart phone, searching the dictionary data using bisection method, listening pronunciation with the use of speech synthesizer, building and editing of vocabulary stored in database are given as the features. A smart phone application for organizing English words was established. The proposed method significantly reduces the organizing time for unknown English words and increases the English learning efficiency.

A three dimensional adaptive finite element refinement algorithm is developed for non-linear magnetostatic field problems. In the method, the edge elements are used for finite element formulation, and the local error in each element is estimated from the fact that the tangential components of magnetic field intensity and the normal components of magnetic flux density should be continuous at the interface of the two adjacent elements. Based on the estimated error, the elements which have big error are divided into several elements using bisection method. The effectiveness of the developed algorithm is proved through numerical examples.

This study was carried out to investigate on the survival rate and in vitro developmental rate of bisected porcine embryos and immature oocytes by manipulator and micropipette. Bisected embryos and immature oocytes cultured for 1∼5 days in TCM 199 medium with 20% FCS. Survival rate was defined as development rate on in vitro culture or FDA-test. The results are summarized as follows ; 1. The survival rate of bisected porcine embryos and oocytes were 26.1%, 22.7%, respectively. The survival rate of bisected embryos and oocytes was significantly lower than that of non-bisection embryos(62.5%). 2. The survival rate of bisected porcine embryos in cultured for 12, 24, 48, 72 hrs with 20% FCS＋TCM-199 medium were 26.9%, 19.2%, 19.2% and 11.5%, respectively. 3. The in-vitro developmental rate with and without zona pellucida of bisected porcine embryos by micromanipulator were 30.8%, 25.0%, respectively.

The purpose of this paper is to investigate the stability of stepped cantilever columns with a tip mass of rotatory inertia and a translational spring at one end. The column model is based on the Bernoulli-Euler theory which neglects the effects of rotatory inertia and shear deformation. The governing differential equation for the free vibration of columns with stepwise variable cross-section and subjected to a subtangential follower force is solved numerically using the corresponding boundary conditions. And the bisection method is used to calculate the critical divergence/flutter load. The frequency and critical divergence/flutter load for the stepped column with a single step are presented as functions of various non-dimensional system parameters: the segmental length parameter, the section ratio, the subtangential parameter, the mass, the moment of inertia of the mass, and the spring parameter.

In this paper, the optimal power allocation algorithm that minimizes the aggregate bit error rate (BER) of the secondary user (SU) in a downlink orthogonal frequency division multiplexing (OFDM) based cognitive radio (CR) system, while subjecting to the interference power constraint and the transmit power constraint, is investigated under the assumption that the instantaneous channel state information (CSI) of the interference links between the secondary transmitter and the primary receiver, and between the primary transmitter and the secondary receiver is perfectly known. Besides, a suboptimal algorithm with less complexity is also proposed. In order to deal with more practical situations, we further assume that only the channel distribution information (CDI) of the interference links is available and propose heuristic power allocation algorithms based on bisection search method to minimize the aggregate BER under the interference outage constraint and the transmit power constraint. Simulation results are presented to verify the effectiveness of the proposed algorithms.

In this paper, we consider secure communications in multi-hop relaying systems, where multiple decode-and-forward (DF) relays are located at each individual hop and perform cooperative beamforming to improve physical layer security. In order to determine the cooperative relay beamformer at each hop, we propose an iterative beamformer update scheme using semidefinite relaxation and bisection techniques. Numerical results are presented to verify the secrecy rate performance of the proposed scheme.
