Objective : To evaluate the clinical results of gross total resection in the surgical approach to spinal ependymoma. Methods : Between June 1995 and May 2009,13 males and 8 females (mean age 34) diagnosed with intramedullary or extramedullary spinal ependymoma were surgically treated at our centre. The neurological and functional state of each patient were evaluated according to the modified McCormick scale. Results : The average follow-up duration was 54 months (ranging from 12 to 168 months). The locations of the lesions were : thoracic region (4, 19%), lumbar region (7, 34%), cervical region (4, 19%), cervicothoracic region (3, 14%) and conus medullaris (3, 14%). Four patients (19%) had deterioration of neurological function in the early postoperative period. The neurological function of three patients was completely recovered at the 6th postoperative month, while that of another patient was recovered at the 14th month. In the last assessment of neurological function, 20 patients (95%) were assessed as McCormick grade 1. No perioperative complications developed in any of our patients. In one patient's 24-month assessment, tumour recurrence was observed. Re-operation was not performed and the patient was taken under observation. Conclusion : Two determinants of good clinical results after spinal ependymoma surgery are a gross total resection of the tumour and a good neurological condition before the operation. Although neurological deficits in the early postoperative period can develop as a result of gross total tumour resection, significant improvement is observed six months after the operation.

By the Article 28 of the Korean Fishing Vessels Act and the Article 47-1 of the Enforcement Ordinance of the Act, fishing vessels over 5 gross tone must be insured the fishing vessels mutual insurance or marine insurance. Therefore the distant-water fishing vessels and vessels registered with Classification Society can be insured to the marine insurance, and non-registered vessels and the small fishing vessels can be insured to the fishing vessels mutual insurance of Fisheries Co-operatives. Moreover, the shipowners of fishing vessels over 5 gross tons to be insured a liability insurance for their crew, and it is to compensate effectively the crewman's accidents prescribed in the Seaman's Act. The shipowner's Liability Insurance to be insured the seaman's Compensation Insurance or the seaman's mutual insurance of the Fisheries Co-operatives and the Protection and Indemnity but they still involve lots of problems to cover the crewman's accidents reasonably. The author's views on the improvement way of the fisheries mutual insurance system are as follows. 1. The size of fishing vessels over 5 gross tons prescribed by the Article 28 of the Fishing Vessels Act must be revised into over 1 gross tons. And the regulations concerning penalties against nonfulfilment of the regulation must be strengthened in order to have legal effectiveness. 2. The level of the government subsidy for the fisheries mutual insurance must be raised up from the large point of view for protection of fishermen. It is concluded that the Government have to take charge of the remutual insurance in order to develop the fisheries mutual insurance system. 3. The mutual insurance system of fish catch have to be executed in order to guarantee the stable income for fishermen on the base of the amount of money by fish catch in the previous year.

Purpose : The present study has been performed to find the effects on gross motor function and balance ability of applying a balance exercise program consisting of motions able to stimulate balance-related sensory systems on various support surfaces along with goal-oriented upper extremity tasks to enhance the balance ability. Methods : 10children diagnosed as having spastic diplegia were selected as the subject for this study, of whom 5children were randomly assigned to a control group (CG) and the remainder to a balance exercise group (BEG) to perform the upper extremity task on various support surfaces. Each intervention was executed 30minutes per session with 2sessions a week for 12weeks. To make comparisons before and after intervention, gross motor function measure; standing; demention D(GMFM;D), walking/running/jumping ;demention E (GMFM;E) and pediatric balance scale (PBS) were evaluated. Results : The CG showed a significant difference (p<.05) in GMFM;E. BEG showed a significant difference (p<.05) in GMFM;D as well as GMFM;E and in PBS before and after intervention. BEG showed a significant improvement (p<.05) in GMFM;D and the PBS compared with the CG whereas it did not indicate any statistically significant difference in GMFM;E. Conclusion : According to the results of this study, it has been shown that a balance exercise accompanied by upper extremity task on various support surfaces had an effect on improvement in the gross motor function and the balance ability of children with spastic diplegic cerebral palsy.

Goal of this study is to perform the correlation about Gross motor function, eating-drinking function, and oral motor function, to identify necessity for invervention of feeding disorders on severity of the function of children with cerebral palsy. Subjects were 61 children diagnosed with cerebral palsy. The subject were evaluated for oral motor function, feeding function by GMFCS, EDACS, OMAS. The results of this study showed a significant correlation between gross motor function, eating and drinking functions, and oral motor functions. That is, the more severe the deterioration of the motor function, the lower the functional level of eating and drinking and oral motor function deterioration. In evaluating and treating the eating activity of children with cerebral palsy through this study, it seems necessary to check the eating and drinking function and oral motor function according to the gross motor function.

Moving train load parameters, including train speed, axle spacing, gross train weight and axle weights, are identified based on strain-monitoring data. In this paper, according to influence line theory, the classic moving force identification method is enhanced to handle time-varying velocity of the train. First, the moments that the axles move through a set of fixed points are identified from a series of pulses extracted from the second derivative of the structural strain response. Subsequently, the train speed and axle spacing are identified. In addition, based on the fact that the integral area of the structural strain response is a constant under a unit force at a unit speed, the gross train weight can be obtained from the integral area of the measured strain response. Meanwhile, the corrected second derivative peak values, in which the effect of time-varying velocity is eliminated, are selected to distribute the gross train weight. Hence the axle weights could be identified. Afterwards, numerical simulations are employed to verify the proposed method and investigate the effect of the sampling frequency on the identification accuracy. Eventually, the method is verified using the real-time strain data of a continuous steel truss railway bridge. Results show that train speed, axle spacing and gross train weight can be accurately identified in the time domain. However, only the approximate values of the axle weights could be obtained with the updated method. The identified results can provide reliable reference for determining fatigue deterioration and predicting the remaining service life of railway bridges.

The anchorage among harbour facilities should ensure sufficient water surface area for safe anchoring. A general method is to consider the L.O.A of the target ship and the depth and bottom quality of anchorage to calculate the water surface area of anchorage. However, the gross tonnage is used as a unit of the ship capacity standard of anchorage based on the detailed rules for harbour facilities operation in Korea. In this study, the gross tonnage is converted to L.O.A to calculate the actual anchoring radius of the target ship. This actual anchoring radius exceeds at 25 anchorages (among 90 anchorages) compared with the designated water surface area. Therefore, as an improvement plan of the ship capacity standard for anchorage, L.O.A should be used as a unit for anchorage based on the detailed rules for harbour facilities operation and related Korean maritime laws.

Background: Although children with cerebral palsy (CP) are able to walk independently, gait imbalance occurs due to abnormal muscle tone, musculoskeletal deformity, loss of balance, and selective motor control impairment. Gait restriction in the community and school is a major problem of rehabilitation in CP. Home-based therapy (HBT) provides a variety of interventions in which the therapist and the parent work together to resolve the activities and problems caused by the child's body structure. Therefore, we investigate the effectiveness of home-centered therapy on gross motor function in CP and try to present the possibility of clinical application. Design: A Systematic Review Methods: Research papers were published from Jan, 2012 to Jan, 2022 and were searched using Medline and PubMed. The search terms are 'family-centered' OR 'home-based' AND 'cerebral palsy'. A total of nine papers were analyzed in this study. The paper presented the quality level based on Physiotherapy Evidence Database (PEDro) scores to assess the quality of randomized clinical trials studies. Results: The results showed that HBT for strengthening exercise in lower extremity has a positive effect on the isokinetic torque and gross motor function. home-based treadmill therapy in CP is effective to perform at least 12 sessions of treadmill HBP in which the therapist determines the treadmill speed every week and the child's own gait pattern is modified. Conclusion: These results suggest that it will be important data for founding evidence on the effectiveness of home-centered therapy on gross motor function in children with cerebral palsy to advance clinical protocols.

Purpose - This paper empirically explores the RCA of electrical equipment trade between China and Korea from the perspective of gross trade and value-added trade. The goal of this paper is to scan the electrical equipment's RCA, the decomposition of gross exports, and the impacts of an exerted shock. Design/methodology - We applied the domestic value-added method in measuring the RCA, which could be more accurate than traditional RCA since it excludes foreign value-added. Based on the research purpose, this paper follows the framework of Koopman, Wang, and Wei (2014)-as extended by Wang, Wei, and Zhu (2018). It extracts the data from the 2019 Multi-regional Input-Output (MRIO) databases compiled by the Asian Development Bank in January 2021. Findings - After rigorous examination, the main findings are as follows: First, the electrical equipment sector maintains a consistent comparative advantage in either assessing method. Second, China exports more gross goods of electrical equipment to the world than South Korea does, but there is a trade deficit with Korea. Third, South Korea and P.R. China are the most significant bilateral partners of foreign value-added sourcing. Finally, it is surprising that there is a shock on electrical equipment; the partner's service, as well as manufacturing sectors, would be affected. Originality/value - This paper explores the revealed comparative advantage between Korea and China from traditional gross export and value-added perspectives. Second, we apply the information from the 2019 MRIO database compiled by the Asian Development Bank in January 2021, reflecting the current situation. Third, this paper analyzes the electrical equipment and the impacts on other parties' sectors. Finally, we carry out the subjects that deserve to be investigated in the future.

Objective: A study was conducted to determine the chemical composition of banana meal and rice bran from Australia or South-East Asia and test the hypothesis that there are no differences in rice bran produced in different countries, but there are differences between full-fat and defatted rice bran. Methods: Two sources of banana meal and 22 sources of rice bran (full-fat or defatted) from Australia or South-East Asia were used. All samples were analyzed for dry matter, gross energy, nitrogen, amino acids (AA), acid hydrolyzed ether extract (AEE), ash, minerals, total starch, insoluble dietary fiber, and soluble dietary fiber. Banana meal was also analyzed for sugars including glucose, fructose, maltose, sucrose, stachyose, and raffinose. Results: Chemical analysis demonstrated that banana meal from the Philippines is primarily composed of starch. Full-fat rice bran from Australia had greater (p<0.05) concentrations of AEE, lysine, and glycine than samples from the Philippines and Vietnam. Full-fat rice bran from Australia and Thailand had greater (p<0.05) concentrations of gross energy and most AA than rice bran from Vietnam. Full-fat rice bran from Australia had greater (p<0.05) concentrations of tryptophan and manganese than all other sources, but full-fat rice bran from the Philippines contained less (p<0.05) zinc than all other sources of rice bran. Gross energy, AEE, and copper were greater (p<0.05) in full-fat rice bran compared with defatted rice bran, but defatted rice bran contained more (p<0.05) crude protein, ash, insoluble dietary fiber, total dietary fiber, AA, and some minerals than full-fat rice bran. Conclusion: Banana meal is a high-energy source that can be used as an alternative ingredient in livestock diets. Full-fat rice bran from Australia and Thailand contained more concentrations of AEE and AA than samples from the Philippines or Vietnam. Full-fat rice bran had more gross energy and AEE than defatted rice bran, whereas defatted rice bran contained more crude protein, ash, and total dietary fiber.

This study was conducted to select candidates from plant resources for the purpose of improving or treating Alzheimer's disease, a type of dementia. One hundred and eighty-four plant extracts at a final concentration of $100{\mu}g/ml$ were screened to determine their capacity to inhibit acetylcholinesterase (AChE) by in vitro assay. From this AChE assay, seven plant extracts - including methanol ext. and water ext. of Phellaodendron amurense Rupr. (bark), methanol ext. of Nelumbo nucifera Gaertn (stamen/ovary), methanol ext. of Persicaria tinctoria H. GROSS (flower), methanol ext. of Coptis chinensis (rhizome), ethanol ext. of Cinnamomum cassia Blume(bark) and ethanol ext. of Carthamus tinctorius L. (fruit) - showed effective inhibition activity ranging from 18.7% to 63.1%. The selected extracts were testified their inhibition activities on AChE and BuChE (butyrylcholinesterase) at concentrations of 25, 50, 100, $200{\mu}g/ml$. In the AChE assay, five extracts including methanol ext. of Nelumbo nucifera Gaertn. (stamen/ovary), methanol ext. of Persicaria tinctoria H. GROSS (flower), methanol ext. of Coptis chinensis (rhizome), methanol ext. and water ext. of Phellaodendron amurense Rupr. (bark) showed inhibition activity of 15.0%~73.5%, 19.5%~63.5%, 81.6%~58.5%, 69.9%~80.5%, and 54.8%~78.3%, respectively, at concentrations of 25, 50, 100, $200{\mu}g/ml$. In the BuChE assay, the extracts of Nelumbo nucifera Gaertn. (stamen/ovary), Persicaria tinctoria H. GROSS (flower), and Coptis chinensis (rhizome) showed inhibitory capacities of 58.9~81.6%, 45.8%~72.4%, and 33.1%~55.4% at concentrations of 25, 50, 100, $200{\mu}g/ml$, respectively. In conclusion, it is suggested that Nelumbo nucifera Gaertn. (stamen/ovary), Persicaria tinctoria H. GROSS, Coptis chinensis (rhizome) and Phellaodendron amurense Rupr. (bark) could be selected as candidate materials for improving or treating Alzheimer's disease on the basis of further study.
