Purpose : To exam the effects of active ankle range of motion(ROM) exercise on sciatic nerve movement and provide the evidence that use it to patients with hypomobile sciatic nerve as a nerve mobilization technique. Methods : The subjects consist of 32 asymptomatic healthy adults(male; 15, female; 17) who have limited passive straight leg raising(PSLR) ranges below 70 degrees. First, examiner measures PSLR angles at three times. Then, subject was instructed perform the active ankle ROM exercise(dorsiflexion and plantarflextion) at limited angle. After each subject completed the active ankle ROM exercise, return the starting position and examiner measures the PSLR angles at three times again. Results : First, PSLR range was no significant differences between dominant and non-dominant leg(p >.05). Second, active ankle ROM exercise significantly increased PSLR range by mean of degrees(p <.05). Third, there was no learning effects among the measurement trials(p >.05). Conclusion : These data show that active ankle ROM exercise can mobilize the sciatic nerve. Therefore, it can be applied to patients with hypomobile sciatic nerve(sliding dysfunction) as a neural mobilization technique.

Though pheasants (Korean ring-necked pheasant) have been raised for several decades, their behavior and wild nature are far from domestication. The pheasant is a seasonal breeding species and lays a limited number of eggs in a breeding season. The growth rate and feed efficiency of pheasants are very low as compaired with those of chicken for meat purpose. In addition, the breeder's access to one's herd for care is not easy. From these reasons, pheasants seem to be unsuitable for meat production in a large flock at present. However, pheasant raising is expected to increase slowly in accordance with rising demand for special poultry meat. Therefore, it is necessary to improve techniques about raising, feeding and rnanagement, so that the consumer price of pheasant meat can be lowered down reasonably.

Objective: This study aims to compare the range of motion of the joints by applying the contraction and relaxation techniques used in manual therapy as electrical stimulation treatment. Based on this, we would like to propose the possibility of using motor nerve electrical stimulation therapy for musculoskeletal physical therapy. Design: Single-arm interventional study Methods: Active and passive straight leg raising tests were performed on 20 healthy men and women in their 20s to measure the angle of hip joint flexion. Then, the electrical stimulation time was set to 10 seconds and 5 seconds of rest, and motor nerve electrical stimulation of 1 Hz was applied with the maximum strength that could withstand the hamstring muscles for 10 minutes. After electrical stimulation, straight leg raising tests again to confirm the range of motion of the hip joint flexion. Results: As a result of this study, it was confirmed that the joint range of motion was significantly improved for both active and passive straight leg raising tests after application of motor nerve electrical stimulation(p<.05). Conclusions: With a strong electrical stimulation treatment of 1 Hz, the effect similar to the contraction and relaxation technique used in manual therapy was confirmed through the joint range of motion. In the future, motor nerve electrical stimulation therapy can be used for musculoskeletal physical therapy to provide a new approach for patients with reduced pain and joint range of motion due to muscle tension.

A field survey of fascioliasis of Korean native cattle raising and raised in specialized commercial breeding farms and local farms in Kangwon province using both intradermal test and sedimentation technique for feces was carried out from November to December, 1996. Fecal samples were taken from fascioliasis positive cattle by the intradermal test for the fecal examination. Liver tissues were randomly collected from an abattoir for histopathological examination of liver fluke infection in cattle. The results are as follows. 1. By the intradermal test for a total of 211 cattle raising in both Wonju and Wheongsung, Kangwon province, 60 heads(28.4%) showed positive reaction. Among 60 positive cattle, eggs of Fasciola hepatica were found from 51 heads(85.0%) by sedimentation technique. 2. According to the cattle raising areas, the positive rates by the intradermal test were 26.7%(20 out of 75 heads) in Wonju and 29.4%(40 out of 136 heads) in Wheongsung. 3. According to the age of cattle examined, the positive rates by the intradermal test in 1~3, 4~6 and 7~10 years old were 11.7%(7 out of 100 heads), 68.3%(41 out of 93 heads) and 20.0%(12 out of 18 heads), respectively. 4. The overall infection rates of fluke larvae from the slaughtered cattle at an abattoir in Wonju was 24.7%(37 out of 150 heads). In histopathology, liver lesions were observed such as inflammation with infiltration of eosinophils, polymorphonuclear cells, mononuclear cells and multinucleated giant cells, proliferation of connective tissues, calcification and abscess formation.

Purpose: The purpose of this study was to determine the effectiveness of direct and indirect methods of contract-relax techniques in proprioceptive neuromuscular facilitation (PNF) stretching for improving hamstring flexibility. Methods: Twenty-six subjects were randomly assigned to either a direct contract-relax technique group or an indirect contract-relax group. For each group, stretching intervention was performed three times a week for a period of two weeks, with 12 seconds for the contraction and 10 seconds for the relaxation per once. The direct contract-relax technique for hamstring flexibility was applied by asking the subject to press down on the shoulder of the trainer in the straight leg-raising position. Conversely, the indirect contract-relax technique was performed by raising the leg with resistance. To facilitate a comparative analysis of hamstring flexibility between the two groups before and after the stretching intervention, two-way repeated ANOVA was performed. Hamstring flexibility for each group was measured using a passive straight leg-raising test. Results: The results showed significant improvement in hamstring flexibility for all subjects in the two groups. However, there was no significant difference between the groups. Conclusion: In conclusion, both direct and indirect contract-relax techniques are confirmed to be useful for improving hamstring flexibility. The choice of suitable technique has to be made individually according to the condition of each subject.

The latissimus dorsi flap is popular due to the versatile nature of its applications. When used as a pedicled flap it provides a robust solution when soft tissue coverage is required following breast, thoracic and head and neck surgery. Its utilization as a free flap is extensive due to the muscle's size, constant anatomy, large caliber of the pedicle and the fact it can be used for functional muscle transfers. In facial palsy it provides the surgeon with a long neurovascular pedicle that is invaluable in situations where commonly used facial vessels are not available, in congenital cases or where previous free functional muscle transfers have been attempted, or patients where a one-stage procedure is indicated and a long nerve is required to reach the contra-lateral side. Although some facial palsy surgeons use the trans-axillary approach, an operative guide of raising the flap by this method has not been provided. A clear guide of raising the flap with the patient in the supine position is described in detail and offers the benefits of reducing the risk of potential brachial plexus injury and allows two surgical teams to work synchronously to reduce operative time.

Background and objective: This study was carried out to develop an effective technique for raising seedlings of Veronica pyrethrina Nakai, a native plant species in the Korean Peninsula, in plug trays. Methods: To investigate the optimum plug cell size and sowing media, we sowed seed in to plug trays with 34, 21, and 10 mL cells and filled with a commercial horticultural substrate and mixtures of peatmoss and perlite in 1:1, 3:1, and 4:1 ratios. Fertilization levels were set at 0, 500, 1000 and 2000 mg·L^-1. Results: Plug cell size did not significantly influence the seedling growth of V. pyrethrina. By substrate type, the growth rate was highest in the horticultural substrate, followed by 4:1, 3:1, and 1:1. Growth by fertilization level was higher in all fertilized treatment groups than in the control group, and there was no difference among 500, 1000, and 2000 mg·L^-1. Conclusion: The results of this study proved that it is most suitable for raising seedlings of V. pyrethrina to sow the seeds in a 10 mL cell plug tray filled with horticultural substrates, and apply fertilizers with less than 500 mg·L^-1 concentration.

Purposes: The purpose is to establish the direction of healthcare R&D through private nonprofit organization. Methodology: The data is divided into two groups: 12 physicians and pharmacists, and 16 persons including professors related to university donation, non-profit foundation executives. Each group was subjected to two Delphi surveys. To analyze the validity of the opinion, the content validity ratio and the consensus of experts were verified. Findings: Funding should be invested in 'development research' and 'application research'. The factors that hinder the donation culture are 'donation prevention system such as tax imposition system and rebate double penalty system', 'insufficient motivation of fund raising person', and 'lack of fund specializing specialist'. The fund raising strategy should be centered on a small number of large donors or a balance between large and small donors. The fund raising target should be effective to raise funds for corporate and individual donors. It is necessary to clarify the purpose of the social problem to be solved by the campaign strategy for promoting donation, to announce the validity of the trust and transparency of the institution, and to emphasize the social investment by the private sector. Practical Implications: It is necessary to present directions through private nonprofit organizations for the future development of healthcare R&D. The legal and institutional deficiencies of the domestic nonprofit organization fundraising infrastructure should be improved. In order to create a social investment climate, it is necessary to improve the awareness of donations and develop various donation programs for the private sector.

In this paper, we propose three compensation methods to solve problems in high-resolution airborne infrared camera and to improve long-range target information acquisition performance. First, image motion and temporal noise reduction technique which is caused by atmospheric turbulence. Second, thermal blurring image correction technique by imperfect performance of NUC(Non Uniformity Correction) or raising the internal temperature of the camera. Finally, DRC(Dynamic Range Compression) and flicker removing technique of 14bits HDR(High Dynamic Range) infrared image. Through this study, we designed techniques to improve the acquisition performance of long-range target information of high-resolution airborne infrared camera, and compared and analyzed the performance improvement result with implemented images.

This paper estimates the gasoline price elasticities of demand for automobile fuel efficiency in Korea to examine indirectly whether the government policy of raising fuel prices is effective in inducing less consumption of fuel, relying on a hedonic technique developed by Atkinson and Halvorsen (1984). One of the advantages of this technique is that the data for a single year, without involving variation in the price of gasoline, is sufficient in implementing this study. Moreover. this technique enables us to circumvent the multicollinearity problem, which had reduced reliability of the results in previous hedonic studies. The estimated elasticities of dam and for fuel efficiency with respect to the price of gasoline, on average, is 0.42.
