Purpose: This study was conducted to examine relationships among job satisfaction, job stress, and self-efficacy and to identify predicting factors on the job satisfaction among a general hospital nurses. Method: The subjects were 266 nurses working at C university hospital in G city. Data were collected using a self-reported questionnaires. The data were analyzed using t-test, one-way ANOVA, Scheffe test, Pearson's correlation coefficients, & multiple stepwise regression by SPSS 12.0 program. Result: The job satisfaction indicated a significant relationship to self-efficacy (r=.310, p<.001) and work stress (r=-.273, p<.001) respectively. The powerful predictors of job satisfaction were general self-efficacy (22.6%), over ￦2,500,000 at monthly income (7.3%), job stress (4.9%), work period at present unit (2.6%), which explained 41.3% of total variance of job satisfaction. It has been confirmed that the regression equation model of this research may serve as a predictor of clinical nurses' job satisfaction. Conclusions: We need to develop self-efficacy promoting and stress relief program for clinical nurses in order to improve job satisfaction.

A 17-year-old-boy with a bilateral incomplete cervical rib, upon abduction of his left arm at 45 degrees, had immediately begun to show symptoms of severe tingling, claudication, pallor, and weakness of his left upper extremity. These symptoms were aggravated at 90 degrees, leaving him debilitated from his work in the printing office. Transfemoral positional subclavian arteriography revealed total occlusion of the subclavian artery immediately distal to a cervical rib during 90 degrees abduction. Resection of the anterior scalene and medial aspect of the middle scalene muscles, cervical and first ribs, and arteriolysis were performed via a combined supraclavicular and infraclavi cular approach. He has returned to work as a printer with marked relief of symptoms and has remained asymptomatic over follow-up periods of 10 months.

The aim of this study were to evaluate the effect of kinesio taping on isokinetic muscular function and pain of knee joint. The subjects for this study were twelve elderly women($65{\sim}70$years) suffered by knee joint pain over more than three years. The taping methods performed on 3 times a week for 8 weeks for improvement of isokinetic muscular function. Also, the change of visual analogue scale(VSA) and varval rating scale(VRA) has been measured before and post taping 8 weeks. Paired t-test was performed for data analysis at the 0.05 level of significance. After 8 weeks, the results of the study are as follow; First, peak torque, peak torque % BW, total work and ipsilateral balance ratio were significantly improved. And, work fatigue, visual analogue scale and verval rating scale were decreased significantly after 8 weeks taping. The results suggest that applying kinesio taping on knee joint may improve isokinetic muscular function of elderly women. Therefore kinesio taping method was effective for pain relief and prevention of knee joint pain in the elderly women.

Purpose: The purpose of this study is to evaluate the effectiveness of low-dose gabapentin for interdigital neuroma. Metrials and Methods: Between April 2000 and June 2003, 32 patients (39 feet) with interdigital neuroma were treated with using low-dose gabapentin. Two of the 32 patients were male, and thirty were female, and the average age was 47.4 years. The follow-up was 6 to 44months (mean 15.1 months). All cases were diagnosed by physical examination and ultrasonography or MRI. Low-dose gabapentin (300-600 mg) was prescribed and shoe modification was recommended. The patients were evaluated through questionnaire. Results: Neuroma was found in twenty one cases at the third intermetatarsal space, and thirteen at the second intermetatarsal space. The sensitivity of ultrasonography was 96% and that of MRI was 79%. Overall satisfaction was rated as excellent or good by 18 cases (57%). Average pain relief ratio was 50.3%, and in 14 cases, more than 80% of pain relief was noted. Nine (28%) of 32 patients showed they had no activity restrictions, such as daily activities or work, whereas 8 (25%) had mild restrictions and 15 (47%) had major restrictions. Twelve of 15 patient with major restrictions had been treated operatively (neurectomy; 10 cases, decompression; 2 cases). One case had gastrointestinal problem. Conclusion: Low-dose gabapentin for interdigital neuroma was one of the effective conservative treatments. The operation may be preserved for patient with the persist symptoms, nevertheless the conservative treatments and use of low-dose gabapentin.

Purpose: Nerve injury is one of the complication which can develop after brow lift. Peripheral nerve ending which is stretched from supraorbital nerve and supratrochlear nerve can be injured and symptoms such as pain, dysesthesia may appear. Usually, developed pain disappeared spontaneously and does not go on chronic way. We experienced a case that a patient complained chronic pain after brow lift which was not controlled by conservative management such as medications, local nerve block and report a successful surgical treatment of chronic pain after brow lift. Methods: A 24-year-old male who received brow lift with hairline incision at local hospital was admitted for chronic pain at the right forehead. The pain was continued for 3 months even though fixed thread was removed. Local nerve block at trigger point with mixed 1 mL 2% lidocaine and 1 mL Triamcinolone acetonide was done and oral medications, Gabapentine and carbamazepine, were also applied but there was no difference in the degree of pain. Therefore the operation was performed so that careful dissection was carried out at right supraorbital neurovascular bundle and adhered supraorbital nerve was released from surrounding tissues and covered with silastic sheet to prevent adhesion. Results: The pain was gradually relieved for a week. The patient was discharged without complications. No evidence of recurrence has been observed for 2 years. Conclusion: The pain developed after brow lift was engaged with nerve injury and sometimes remains chronically. Many kinds of conservative management to treat this complication such as medications, local nerve block have been reported and usually been used. But there are some chronic cases that conservative treatment do not work. In sum, we report 1 case of successful surgical treatment for relief of intractable pain developed after brow lift surgery.

In this work, a circuit with a hydraulic power unit is formulated as a means of predicting the behavior of the prefill valve in the future. The behavior of the prefill valve can be examined by the measurements of the configured power unit, and the performance is determined by using hydraulic pumps, relief valves, and hydraulic hoses that make up the power unit. In particular, pressure/flow pulsation generated by hydraulic pumps can cause instability in the prefill valve and cause noise-induced degradation of the overall performance and reliability of the hydraulic system containing the prefill valve. Therefore, to study the behavior and performance of the prefill valve in a relatively accurate manner, the prediction of the characteristics of the hydraulic power unit driving the prefill valve is very important. In this study, the pulsation characteristics of the hydraulic pump were analyzed to theoretically demonstrate its relationship with different settings of the power unit, such as relief valve pressure settings and the presence/absence of the hose.

Air balancer is a conveyance cargo-handling machine, used in assembly and process lines of car and machining industries. This can lift up an object, the weight of which is from 5 to 200 kg, and moves it to a position. As industrial technologies evolve, it is required to move an object and fit it into a specified position with greater accuracy, rather than performing simple tasks such as lifting objects up and down as conventional ones do. There is also a demand to handle an object with one hand, rather than with two hands,. Through designs of manifold unit for an air balancer function, pilot regulator unit to keep pressure constant, hand unit for an accurate load perception function, and air balancer circuit, this study enables everybody to work it with ease and convenience. Experiments and comparisons were conducted for the performance evaluation of the circuit.

The destruction of river and damage caused by flood are suddenly increasing due to the abnormal climate. In the investigation result about the damage, approximate 52% of the destruction of embankment are caused by earth work. Moreover, to recover conveyance of relief channel, bed sediment is dredged about 198 millions $m^3$ with 'the project of bed dredging'. So, the concern for bed sediment is the more increasing, the requiring high quality material for banking and the way for application of bed sediment are also the more increasing. In this paper, properties of bed sediment were analyzed through sedimentary mechanism analysis. Moreover, possibility to build embankment with bed sediment in 6 points which is in catchment of the Nak-dong river was also analyzed. At 6 points, which were selected to survey easily, sediment discharge was analyzed with formula. Moreover, size and permeability were analyzed and the feasibility for material of embankment was proposed. If bed sediment wasn't proper, complementary measures were proposed.
