The notion of the 'court' is most unique to ICC arbitration. This paper focuses on what the court is and how it works and what the role and the duties of the Court under the ICC arbitration imply for the KCAB International Arbitration Rules. The Court is an administrative body that administers arbitrations taking place under the ICC Rules of Arbitration. The Court consists of 126 members from 88 countries around the world. Court members participate in decision-making process by way of attending the committee sessions and plenary sessions. At the Court's committee sessions, the Court fixes advance on costs; reviews the prima facie existence of arbitration agreements; fixes the place and language of arbitration, and the number of arbitrator(s); confirms and approves arbitrators; scrutinizes draft awards, determines the costs of arbitration; decides on extensions related to Terms of Reference, draft awards and correction and interpretation of the awards. At the Court's plenary sessions, the Court performs only two responsibilities: the challenge or replacement of arbitrators or the scrutiny of draft awards. The Court is required to scrutinize draft awards involving states or state entities, drafts with huge amounts in dispute or complex technical or legal questions, and as well as draft awards to which a dissenting opinion has been attached. Turning to the KCAB International Arbitration Rules, Article 1(3) provides that the KCAB shall establish an International Arbitration Committee. Further, it is provided that the KCAB shall consult with the said Committee with respect to challenge and replacement/removal of arbitrators pursuant to Article 1(3). The notion and role of the International Arbitration Committee was originally adapted from the Court to ICC arbitration, but its role was quite reduced in the process of enactment of its Rules. Accordingly, I examined the detailed roles of the Court to ICC arbitration in this paper and hereby suggest that the KCAB International Arbitration Rules shall be amended in the following ways: The Secretariat of the KCAB shall: fix advance on costs at the first stage and the costs of arbitration at the final stage of the proceedings; determine the number of arbitrators; review the prima facie of existence of arbitration agreement; confirm arbitrators; decide extensions related to time table, draft awards and correction and interpretation of the awards. I, also, suggest that the arbitral tribunals shall fix the place of arbitration and the language of arbitration and make a final decision on the validity of arbitration agreement. With regard to the International Arbitration Committee, it is desirable for its Rules to empower the Committee to recommend any prospective arbitrator and to review and decide challenge and replacement/removal of arbitrators.

This paper proposes a replacement policy following the expiration of a non-renewing free replacement-repair Warranty(NFFRW). The non-renewing free replacement-repair warranty is defined and then the maintenance model following the expiration of the NFRRW is studied from the user's point of view. As the criteria to determine the optimality of the maintenance policy, we consider the expected cost rate per unit time from the user's perspective. All maintenance costs of the system incurred after the expiration of the warranty are paid by the user. Given the cost structures during the life cycle of the system, we determine the optimal maintenance period following the expiration of a NFRRW. Finally, the numerical examples are presented for illustrative purposes.

The purpose of this study was to investigate the purchasing behavior and selection attributes for Home Meal Replacement (HMR) and to identify the selection attributes affecting purchasing frequency and purchasing costs of married women living in a city. Among 837 questionnaires distributed to HMR married women consumers, 752 complete questionnaires (89.8%) were analyzed. The younger married women group showed higher frequency of purchasing HMR than the older age group. The 20s and 30s age groups showed higher purchasing costs for HMR than the 40s and older age groups. A higher proportion of employed married women purchased HMR three or more times per week and spent an average of more than 20,000 won per purchase in comparison with unemployed married women. HMR selection attributes were classified into five factors: 'taste and sanitation', 'economic efficiency', 'health and nutrition', 'convenience', and 'reliability and awareness'; mean scores of these factors' importance levels were 4.28, 3.93, 3.59, 3.54, and 3.50 out of 5 points, respectively. The importance level of 'taste and sanitation' factor was significantly greater as married women's age decreased. However, the importance level of 'health and nutrition' factor was significantly greater as married women's age increased. The results of the logistic regression analyses indicate that the 'taste and sanitation' and 'health and nutrition' factors affected frequency of purchasing HMR. The 'reliability and awareness' factor had the most significant impact on cost per purchasing HMR. Therefore, a product differentiation strategy according to married women's age and employment status should be applied. Product qualities and brand value should be improved to enhance competition in the HMR market.

Factors which affect largely the economics of lighting system, are initial installation costs, maintenance costs, energy costs as so on. In these costs, maintenance cost, lamp replacement labor cost, luminaire cleaning cost et al. so the economics of lighting system are evaluated different by maintenance planning. It is important to evaluate which lighting system would be economically advantageous in a initial design. In this study, the importance of maintenance factor is verified by the evaluations of the economics of lighting systems while maintenance factor is varied composition factors in ZCM which is used to calculate the average illuminance.

In Korea ranking sixth out of The world's greenhouse gas emissions, all Korean public buildings have to implement obligatorily renewable energy systems for energy production to reduce the greenhouse gas emissions from the energy consumed in operation, maintenance and management of buildings. The optimum combination and application rates for each energy source emerge from analyzing the trend of previous studies and the energy consumption is simulated by using a dynamic energy simulation program and the initial investment costs, the energy costs, the maintenance costs, the replacement costs emerge based on the calculated result. The result show that the total life cycle cost of 100% gerthermal is the lowest with \ 2,105,974,344 on the analysis results.

This study analyzes the effects of the obsolescence assets on the asymmetry of costs. Cost asymmetry refers to a lower percentage of costs when sales fall than increases in costs when sales increase. the obsolescence asset induces various decisions, including high maintenance costs and management improvements and replacement of facilities. This study is to analyze the cost behavior according to those decisions. The analysis showed that the higher the obsolescence of assets rate, we found cost elasticity, with a greater reduction in costs when sales decrease than the increase in costs when sales increase. Second, the lower the cost will not appear as the obsolescence of assets rate increases in case that the concentration of an item of property, plant and equipment is high, and when sales decrease. The above result means that the obsolescence of assets rate acts as operating risk and thus operates resources flexibly according to changes in sales, but when the concentration of property, plant and equipment is high, the decision-making constraint make it difficult for the flexible operation.

Conventional HP(high pressure) sodium or Metal-halide lamps have a life span of around one year requiring at least annual replacement and maintenance. High Power LED lights require no regular maintenance further increasing savings on replacement bulbs, access equipment and labour costs. New installations benefit from a substantial reduction in the cost of expensive heavy duty cable required for sodium lighting. Especially, LED light can achieve variable color temperature, high functional performance in the field of street light. There are two main method to achieve variable color temperature function of the street light. one method is using RGB multi-chip LED, the other is using Orange-White LED method. In this paper, it was compare RGB Multi-chip LED with white-orange LED for there characteristics performance.

This paper concerns with preventive replacement under periodic inspections for an item (system) which is in a state of preparedness. The item is subject to wear. The item fails randomly but the failure rate depends on the accumulated wear. The item is preventively replaced if it survives a certain wear limit at periodic inspections. The foiled item is, however, replaced at periodic inspections. Given the costs for replacements and inspections, and the penalty cost of the time elapsed between failure und its detection, the optimal wear limit according to the long-run expected cost per unit time criterion is derived. It has been proved that the optimal wear limit is unique if an item has increasing weer-dependent failure rate. A numerical example for a stationary gamma wear process with Weibull distributed failure is given to show its applicability.

Surgeons are increasingly using the right mini-thoracotomy approach to perform aortic valve surgery. This approach has shown better results in terms of blood loss and length of hospital stay than the sternotomy approach. For selected patients requiring aortic root and ascending aorta surgery, a right mini-thoracotomy approach may prove beneficial. In our technique, we placed a 5-cm horizontal skin incision in the right second intercostal space. Femoro-femoral cardiopulmonary bypass was established. A valved aortic conduit was used for aortic root replacement. The patient's postoperative course was uneventful, with a short hospital stay. This technique offers a minimally invasive approach to aortic root and ascending aorta surgery with easy adaptability and reduced costs.

Contemporary embedded systems often use NAND flash memory instead of hard disks as their swap space of virtual memory. Since the read/write characteristics of NAND flash memory are very different from those of hard disks, an efficient page replacement algorithm is needed for this environment. Our analysis shows that temporal locality is dominant in virtual memory references but that is not the case for write references, when the read and write references are monitored separately. Based on this observation, we present a new page replacement algorithm that uses different strategies for read and write operations in predicting the re-reference likelihood of pages. For read operations, only temporal locality is used; but for write operations, both write frequency and temporal locality are used. The algorithm logically partitions the memory space into read and write areas to keep track of their reference patterns precisely, and then dynamically adjusts their size based on their reference patterns and I/O costs. Without requiring any external parameter to tune, the proposed algorithm outperforms CLOCK, CAR, and CFLRU by 20%-66%. It also supports optimized implementations for virtual memory systems.
