Systems of products inspection being utilized in international transactions of products and its countermeasures. Some developing countries are strengthening clearance management such as carrying out inspection on qualities of the products to be imported and on appropriateness of its price prior to shipment from exporting countries in order to prevent irrational practice such as tax evasion and assuring effectiveness in control of foreign exchange in connection with international transaction of products through commissioning such duty for inspection to professional agencies. In this treatise this author addressed WTO's regulations with regard to the preshipment inspection system in connection with exportation to developing countries as one of strategy for exportation by our country and recommended relevant counter-measures: Main counter-measures should include. First, legislation of relevant system in the country, Second, fostering inspection agencies and relevant enterprises in Korea. Third, search for ways to exempt inspection of products with an amount below a certain level; Fourth, presentation of list of transaction price in advance, And finally, strengthening penalties for irregular trade transactions.

The penalty method has been widely applied to analyses of incompressible fluid flow. However, we have not yet found any prior studies that employed penalty method to analyze compressible fluid flow. In this study, with an eye on the apparent similarity between the slight compressible formulation and the penalty formulation, we have proposed a new approximate approach that can analyze compressible packing process using the penalty parameter l. Based on the assumption of the isothermal flow, a set of reference solutions was obtained to verify the validity of the proposed scheme. Furthermore, we have applied the proposed scheme to the analysis of the packing process of different cases.

Objective: To determine the effectiveness of pulsed electromagnetic fields (PEMF) in the treatment of knee osteoarthritis (OA). Methods: In this randomized, placebo-controlled, double-blind trial, 51 patients with knee OA, diagnosed according to the criteria of the American College of Rheumatology, were treated with PEMF or placebo. Eleven patients failed to attend after screening and were excluded from analysis. Treatment consisted of 3 half-hour periods of exposure per week over 6 weeks in a specially designed cylindrical device that emits low-frequency pulsed electromagnetic fields (25 gauss, 12 Hz). The primary outcome measure was reduction in pain on movement using a 10 cm visual analog scale. Secondary outcome measures included joint swelling and tenderness, the Lequesne index, and overall evaluations of improvement by the patient and examining physician. Evaluations were made at baseline, 3 week and 6 week during treatment and 4 weeks after finishing treatment. Results: There were no significant differences between PEMF and placebo groups in respect of any outcome measures after treatment. Range of motion and knee swelling tended to be improved in the PEMF group. There were no clinically relevant adverse effects attributable to PEMF treatment. Conclusion: These results suggest that the PEMF treatment has no clinically significant benefits in patients with knee OA resistant to conventional treatment. The larger studies are needed to confirm the efficacy of PEMF therapy in knee OA.

The purpose of this study was to investigate the distribution of V˙O₂max in Taekwondo competition. Subjects as a T group were seven well-trained Taekwondo players. Control group was composed of seven healthy male students who taking Taekwondo club in D university. With K4b2 telemetry, V˙O₂max was determined for each subject by administering a treadmill exercise test(5% slope, start speed: 120m/min, increased 20m/min each 2min). Data were analyzed by ANOVA with post hoc-test The 0.05 level of significance was as critical level for the study The study has shown that covering all round in the Taekwondo competition, the Taekwondo player group was over 81% V˙O₂max 55.88%, 71~80% V˙O₂max 17.20%, below 70%, V˙O₂max 26.92%, and the control group was over 81% V˙O₂max 17.35%, 71~80% V˙O₂max 14.55V˙O₂max, below 70% V˙O₂max 38.10%. Putting the above-mentioned together, we can assume that in the Taekwondo competition. energy recruitment is anaerobic 55% or so, aerobic 45%, and that CPK is related to ATP-PC system, while lactate and LDH are connected with lactate system. To develop performance of Taekwondo, it is fit that training have to be composed of 60% over 81%V˙O₂max at least. In the future. I think that it will he necessary to find how to classify the ratio of ATP-PC system which was brought about in the Taekwondo competition. that of lactate system and aerobic on the metabolism.
