Optimal sensor placement techniques play a significant role in enhancing the quality of modal data during the vibration based health monitoring of civil structures, where many degrees of freedom are available despite a limited number of sensors. The literature has shown a shift in the trends for solving such problems, from expansion or elimination approach to the employment of heuristic algorithms. Although these heuristic algorithms are capable of providing a global optimal solution, their greatest drawback is the requirement of high computational effort. Because a highly efficient optimisation method is crucial for better accuracy and wider use, this paper presents an improved simulated annealing (SA) algorithm to solve the sensor placement problem. The algorithm is developed based on the sensor locations' coordinate system to allow for the searching in additional dimensions and to increase SA's random search performance while minimising the computation efforts. The proposed method is tested on a numerical slab model that consists of two hundred sensor location candidates using three types of objective functions; the determinant of the Fisher information matrix (FIM), modal assurance criterion (MAC), and mean square error (MSE) of mode shapes. Detailed study on the effects of the sensor numbers and cooling factors on the performance of the algorithm are also investigated. The results indicate that the proposed method outperforms conventional SA and Genetic Algorithm (GA) in the search for optimal sensor placement.

Purpose - This study aims to examine the incremental information content of cash flw from operations and earnings in the Iranian capital market. Design, methodology, and approach - Based on market-based accounting research, this study uses statistical associations between accounting data (earnings and cash flw) and stock returns to assess/measure the incremental information content (value relevance) of cash flw and earnings. A multivariate regression model based on panel data is used to examine the incremental information content of earnings and cash flow from operations. Results - The results show that both earnings and cash flow from operations have incremental information content beyond each other. These results are consistent with the findings of recent studies. Overall, the fidings of this study support the usefulness of cash flw information in addition to earnings, in fim valuation by investors in the Iranian market. Conclusions - The study makes the following contributions to the Iranian literature on incremental information content of cash flw and earnings. First, this study employs actual cash flw data derived from cash flw statements. Second, this study employs a large sample size for a more recent period.

FIMS (Far-ultraviolet IMaging Spectrograph) is the main payload of STSAT-1 satellite which was successfully launched on September 27, 2003. The optical system of FIMS consists of two sets of parabolic cylinder mirror, slit, ellipsoidal reflection grating, and baffle system. We designed two types of baffle system for the FIMS: FOV baffle and order baffle. FOV baffle in the mirror house controls the field of view, and the order baffle in the vacuum box blocks the rays reflected rays by different orders.

The purpose of this study was to investigate the changes of the activities of daily living (ADL) by the motor learning program for upper extremity in stroke patients. The subjects were sixty-two members who were treated at the department of occupational therapy. The ADL were measured with Functional Independence Measure (FIM). The result's were as fol1ows; 1. The ability to perform daily activities after treatment was significantly increased independent of age, gender, cause, affected side and speech disability (p<.01). The differences between the pre-treatment and the post-treatment was no significant correlation to sex, cause, affected side and duration of treatment, but the speech disability was significant. Therefore the pre-treatment scores and post-treatment scores were significantly different. 2. The variation of the pre-treatment and the post-treatment in the detail item to the performance of daily life of the stroke patients through the upper extremity motor learning program was significantly increased in self-care, sphincter control, locomotion, mobility, communication and social cognition (p<.01) Consequently, The motor learning program for upper extremity significantly improved the performance level of all ADL areas in stroke patients.

Purpose: This study was to develop and evaluate stability and effects of an early exercise program for patients with open heart surgery. Methods: The subjects of this study were 30 patients who had either a coronary bypass surgery or a valvular heart surgery at a tertiary hospital in Seoul. The data was collected by observation and measurement from October 1, 2004 to November 15, 2004. Results: The early exercise program developed for this study consisted of range of motion exercise and walking. Intensity of walking was 1~3 METs and increased progressively to daily target distance. During exercise, the subjects were monitored heart rate, blood pressure and RPE (Rating of Perceived Exertion). The mean FIM (Functional Independent Measurements) score of subjects was significantly improved after the early exercise program. However, several complaints such as dizziness or pain were also reported. Most complaints were associated with chest tube and RPE. Conclusion: The early exercise program can help to recover patients' physical activities after surgery, and can be applied to most patients. Patients' RPE, dizziness and pain was possible limitations, therefore, active pain control and prevention of accidents for patients would be needed.

Some hemiplegic patients show a particular posture that pushing away from the nonaffected side of the body. A few study has been conducted of any aspect of this syndrome. But despite the lack of a scientific basis, this term is widely used in the physical therapy of hemiplegic patients. The purposes of this study was to investigate whether pusher syndrome has an adverse impact on functional outcome. Included were all acute stroke patients admitted in a months period a hospital in Seoul. The presence of pusher syndrome was assessed by a Bobath trained physical therapist. The ability of transfer was assessed by the Functional Independence Measure(FIM), Activities of daily living by the Modified Barthel Index(MBI), and standing balance by Bohannon's Standing Balance Scale(BSBS) on admission, weekly during the hospital stay, and at discharge. Pusher syndrome was found in $52.4\%$ of the left side and $50.0\%$ of the right aide hemiplegic patients. Significant differences were found in the score of transfer, ADL and standing balance between patients with and without pusher syndrome.

Purpose: The electrochemical corrosion behavior of tin oxide film coated on PET substrates has been studied under varying concentrations of acrylic acid to investigate possible corrosion in contact with the acidic environment. Method: Potentiodynamic test was performed for a commercial ITO/PET film in 0.1, 0.3, and 0.5 M of acrylic acid. The surface morphology was analyzed by scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). Results: Potentiodynamic test results showed an increase in Icorr and decrease in Ecorr value with increasing concentration of acid. Microscopic evaluation suggested the presence of certain deep cracks on the surface of the film in addition with a severe acidic attack. Conclusion: Exposure of ITO to acrylic acid resulted in the stress corrosion cracking of ITO film due to the mechanical mismatch between brittle inorganic ITO fim and a compliant organic PET substrate leading to the subsequent failure of the film.

Neuromyelitis optica (NMO) is an autoimmune inflammatory disorder of the central nervous system characterized by optic neuritis and longitudinally extensive myelitis. Painful tonic spasm is a common complication of NMO, but there have been no reports about it in Korean medicine studies. In this case, we treated a 53-year-old woman diagnosed with NMO with paraplegia, painful tonic spasm, and decreased visual acuity using Korean medicine treatment, including acupuncture, herbal medicine, cupping, and moxibustion. We measured changes in clinical symptoms using the manual muscle testing (MMT), the numeric rating scale (NRS), the modified Barthel Index (MBI), and the Functional Independence Measure (FIM). After treatment, clinical symptoms were improved. The results indicate that Korean medicine treatment may be effective in the treatment of an NMO patient with paraplegia and painful tonic spasm.
