Bio-degradable hydraulic oil using polyolester base oil is formulated for the applications of heavy duty hydraulic machineries. It has proved quality and market price competitiveness by assessment of reliability test in vehicle manufacturer and specific vehicle related institute. Contribution of bio-degradable oil keep the working environment clean and increase export competitiveness in European market. Leakage or waste of mineral types of hydraulic oils in heavy duty machineries causes pollution of river, ocean, underground water. Drinkable-water pollution is serious problem in Europe. In some European countries, using bio-degradable hydraulic oils become an obligation in heavy duty machineries. New product of bio-degradable oils satisfy the European regulations(OECD 302B) and shows excellent performance in compare with European products.

We consider the question of warranties for repairable items. During the warranty period, each time an item fails the manufacturer has the obligation to restore the item to operational condition either by repairing the item or by replacing it by a new item. In this paper, we consider a warranty policy for making this decision based on the condition of the failed item. For products with phase-type lifetime distributions where the phases represent the condition of the item, we develop algorithms to determine the expected cost of servicing a warranty and use it in making the repair/replacement decision. illustrative numerical examples are presented.

International Factoring transaction in Korea is different from that of financially advanced countries in terms of legal system and commercial and financial practices. As for the domestic factoring, Korean factors are only involved in advances often on a with recourse basis. With regard to the international factoring, Korean factors do not accommodate whole account receivables from clients (suppliers) but handle on a selective basis. Among Korean banks, KEXIM (Export and Import Bank of Korea) is sole factor for international transactions. Currently KEXIM and several foreign banks handle factoring provide factoring services with limitation to invoice discounting which is largely extended to large corporate names. Therefore this is far different from factoring in Europe and Americas designed for small exporters with non recourse advances. In respect of legal environment, receivable assignment is subject to debtor' acknowledge or approval of such assignment according to Civil Law Act. To remove the legal obstacles, Korean government have prepared new law which allows factor's own notification of assignment (and thereby reimbursement right) to debtor with some evidences.

In modern industrial society carriage of dangerous goods by sea becomes more increasing than ever before. Dangerous goods are required for special care and handling in that shipment of dangerous goods could affect safety of the vessel and other cargoes. It is also true that dangerous goods could be used as a means of terrorism. his article investigates allocation of risk and liabilities between parties involved in the carriage of dangerous goods by sea. More specifically, this study examines principles of strict liability of the shipper in shipment of dangerous goods with some limitations based upon recent cases. Furthermore this article investigates the issues on identity of shipper who bears strict liability to the carrier where there exist actual or documentary shipper other than the contractual shipper. Lastly, whether it is reasonable that the transfer of strict liability to the transferee, who does not have opportunity to verify dangerous nature of the goods before shipment, by endorsing bills of lading will be discussed critically.

Background: Various functional factors should be incorporated during assessment and intervention for patient rehabilitation. Stable respiratory function is one of required factors for functional restoration. To maximize respiratory physical therapy intervention outcome, it is required to understand clinical features of respiratory diseases and physical therapy approaches. Methods: Previous studies were systematically reviewed through computerized search. Methodological qualities of selected studies were evaluated and the levels of recommendations were determined. Results: Assessment for respiratory pattern and thoracic mobility is of importance to improve cardiopulmonary fitness during physical reconditioning. Application of optimal therapeutic protocol can increase thoracic mobility and respiratory function. Interdisciplinary communication is critical during rehabilitation for respiratory patients. Health care provider should have professional knowledge and experience for cardiopulmonary fitness and obligation to endeavor for patients' respiratory rehabilitation. It is necessary to standardize therapeutic intervention, and rehabilitative respiratory exercise should be applied to confirm the effects of intervention. Conclusion: Respiratory diseases that may reduce patients' quality of life and cardiopulmonary fitness should be resolved through physical therapy approaches. Through conducting research, effect of evidence-based and patients' function-oriented intervention can be determined.

Consumption of fossil fuel has been increasing steadily, and it has seriously affected environment. Due to this situation, UN establish ed UNFCC (United rations Framework Convention on Climate Change), and since Feb. 2005, Kyoto Protocol has come into effect for UNFCC obligation. In Korean power system, coal and oil thermal generation emitting large CO2 form about 46% of total generation. Moreover since electricity dem and has been increasing continuously, various alternatives should be designed to comply with Kyoto Protocol. In this paper, we analyze changes of each GENCO's generation pattern and resource planning under CO2 emission constraints. For this analysis, we incorporate CO2 emission constraints and the emission trading mechanism into the conventional OPF model.

Defense offset is considered to be all effective way of acquiring defense critical technologies and arms components as a counter-trade obligation ill defense acquisition contracts. Although arranging the offset contracts is wide]y perceived as necessary, there hardly exists an acceptable model of valuation of the offset technology. By undertaking the technology valuation approach and applying the option approach tn the offset program, we present an offset technology valuation model that maximizes social net benefit of the countries transferring the technology. This article applies our model to an actual case of defense technology transfer in the Republic of Korea. The contribution of this paper is in applying the option approach to the valuation of defense onset technology, providing for the additional flexibility to tile analysis. Our research suggests several policy implications that can be applied to the actual process of defense offsets. Our results elucidate managers' role and responsibilities in designing such a process by applying option approaches.

This paper tries to show the appropriate estimation method of oil pollution damage for mariculture fisheries. The International Oil Pollution Fund 1992(also known as the IOPC Fund 1992) has made up the Claims Manual to assist claimants by giving a general overview of the Fund's obligation to pay compensation. Section III of the Manual provides more specific information to assist claimants in presenting their claims concerning about economic losses in the fisheries, mariculture and fish processing sectors. The paper tries to suggest reform proposals for current etimation method of damages of maricluture fisheries contaminated by oil spillover using the population biology of living resources charaterized with age distribution.

This study was formed to propose a theoretical background trying to create a positive delivery experience by understanding college women's subjective accounts (their view and attitude) on delivery. Method: Q- methodology was used to appreciate the highly abstract concept in an objective manner, since delivery can be assessed differently with each experience. Result: There were three types of opinions about the delivery in college women. The first type (matured type) understood delivery to be a precious experience that enables women to gain the value of life through labor pain, and granted then more appreciation to their own mothers. The second type (will type) recognizes delivery as an option rather than an obligation for women. They think women chooses whether or not to experience the process, especially since delivery requires a great deal of responsibility. The third type (positive type) takes delivery as a valuable, worthwhile, and marvelous process that they wish to experience. They are not even afraid of giving birth multiple times. Conclusion: The study explains and allows us to understand college women's overall opinion and attitudes about delivery. Thus this study aids the seizure of an opportunity to build a theoretical base for delivery management.
