Mediation and Arbitration are two distinct ADR processes. Their dissimilarity lies in the principle that in mediation the parties themselves decide what the resolution to the problem is, whereas in arbitration the arbitrator makes that determination. Med-Arb, hybrid of the two methods, is a fairly new ADR process dating back to the 1970s. Med-Arb capitalizes on the advantages of both mediation and arbitration, while eliminating many of their disadvantages. Mediation has the advantage of allowing for resolutions rather than decisions. Arbitration has the advantage of guaranteeing that the matter will be resolved when the procedure is over. In Med-Arb, the participants agree to be parties to mediation, and if the mediation comes to an impasse, a final settlement will be reached through arbitration. This study first explicates the origin and the development of Med-Arb in the United States. This study shows that the emergence of Med-Arb is benefited from the fact that arbitration has lost its own advantages ie, speed, cost-saving, and maintenance of an ongoing relationship between the disputants. Second, this study analyzes four cases in which Med-Arb is applied to various kinds of disputes as a tool of dispute resolution: labor disputes, entertainment disputes, will disputes, and international commercial disputes, consecutively. All those case studies show the generality of Med-Arb as a dispute resolution channel. Third, this study compares the advantages and disadvantages of Med-Arb. Finally, this study discusses the implications of Med-Arb. In particular it provides the universality of this hybrid form of dispute resolution in the East and West. For example, we show that China has its own distinctive Med-Arb system, where it has developed from ancient Confucian philosophy. Japan also emphasizes the role of an arbitrator who settles the disputes in the course of arbitration. The domestic arbitration rules of the Korean Commercial Arbitration Board (KCAB) have a similar process in that arbitration contains an element of conciliation. With regard to the universal characteristics of Med-Arb, it is necessary to analyze the pros and cons of Med-Arb at a deeper level in the future. One caveat is that it is necessary to handle the issues of the neutrality of the mediator-arbitrator.

For the seafloor acoustic image mapping of side scan sonar, the beginning step of the procedure is to fix the absolute sonar (tow-fish) position since the sonar is not hull mounted but towed astern. The technical algorithm used to calculate the actual sonar position without any other additional sub-system, i.e., the underwater acoustic position tracking system or the sonar attitude measuring device, was proposed. In the seafloor image mosaic mapping results using the sonar track (not ship track) developed in this study, any ambiguity or inconsistency of seafloor features was not found. The incidental effect from the sonar position determination procedure orients the towing direction of sonar to be smooth, consequently the swath pattern on the across-track direction becomes stable and the blanking phenomenon of the insonification area is reduced conspicuously. This technical method is considered to be an useful tool when applied toother underwater towing vehicle surveys.

Purpose: This study was conducted in order to evaluate how chemiluminescent lighting($ViziLite^{(R)}$) could increase the sharpness of margin and contrast to normal mucosa in the diagnosis of oral lichen planus(OLP), the most frequent oral premalignant lesion, compared with direct visual inspection under incandescent light. Methods: 41 consecutive patients, diagnosed to have OLP with visual inspection under incandescent light, were further examined with chemiluminescent light. The degrees of margin sharpness and lesion contrast were ranked on a scale from 1 to 3 for all patients under visual inspection and chemiluminescent light. The presence of additional lesion only detected by chemiluminescent light, complication, and discomfort were checked for each patient. After both screening tests, biopsy specimens were harvested from all patients with scalpels and histopathologic assessments were done. Results: All 41 patients were diagnosed to have OLP by both visual inspection and chemiluminescent light examination. This result was definitively diagnosed by histopathology. Degrees of margin sharpness and lesion contrast were increased by chemiluminescent light compared with visual inspection, but only the difference of lesion contrast was statistically significant. In 22.0% of patients, additional lesions were detected and 88.9% of them were diagnosed to have OLP histopathologically. 17.1% of patients noted discomfort and 9.8% of patients showed complications after chemiluminescent test. Conclusion: Chemiluminescent light may not be proper for the screen test of oral cancer or premalignant lesion but showed some possibility for additional diagnostic tool for definitively diagnosed patients in determination of lesion margin and scope.

This study of culturing testicular cell types in vitro has potential to be an invaluable tool for assessing the mechanisms of testicular toxicity, especially those of intragonadal interaction and spermatogenesis. Combined with the Sertoli/germ cell cultures, Leydig cells provide comprehensive and detailed information on the action of testicular toxicants at the level of the testis. Sertoli/germ cell were isolated and incubated well in vitro from 20~30 g rats and Leydig cells from 250~300 g rats. The Sertoli cells isolated from the testis of the SD rats grew into monolayer on about the 2nd~3rd day of culture, an appreciable cell increment being observed between the 4th~5th day. The Leydig cells isolated from the testis of the SD rats grew into a monolayer on about the 3rd-4th day of culture, an appreciable cell increment being observed between the 5th-7th day. These results suggest that Sertoli and Leydig cells can be cultured as a male fertility evaluation method alternative to the in vivo/conventional fertility test method and further study for the physio-chemical determination is needed.

Slabs in buildings and bridge decks, which are restrained against lateral displacements at the edges, have ultimate strengths far in excess of those predicted by analytical methods based on yield line theory. The increase in strength has been attributed to membrane action, which is due to the in-plane forces developed at the supports. The benefits of compressive membrane action are usually not taken into account in currently available design methods developed based on plastic flow theories assuming concrete to be a rigid-plastic material. By extending the existing knowledge of compressive membrane action, it is possible to design slabs in building and bridge structures economically with less than normal reinforcement. Recent research on building and bridge structures reflects the importance of membrane action in design. This paper describes the finite element modelling of membrane action in reinforced concrete slabs through optimisation of a simple concrete model. Through a series of parametric studies using the simple concrete model in the finite element simulation of eight fully clamped concrete slabs with significant membrane action, a set of fixed numerical model parameter values is identified and computational conditions established, which would guarantee reliable strength prediction of arbitrary slabs. The reliability of the identified values to simulate membrane action (for prediction purposes) is further verified by the direct simulation of 42 other slabs, which gave an average value of 0.9698 for the ratio of experimental to predicted strengths and a standard deviation of 0.117. A 'deflection factor' is also established for the slabs, relating the predicted peak deflection to experimental values, which, (for the same level of fixity at the supports), can be used for accurate displacement determination. The proposed optimised concrete model and finite element procedure can be used as a tool to simulate membrane action in slabs in building and bridge structures having variable support and loading conditions including fire. Other practical applications of the developed finite element procedure and design process are also discussed.

Recently, a very large vessel's maneuvering performance, rudder performance and rudder design's importance is considered to be an important subject. There have been few studies on the design process of rudder device before. The aim of this paper is to investigate a design process of rudder device and to propose a generalized design process of rudder device. Firstly, we investigated the rudder device design process of Korean major shipyards. And the differences of a torque calculation method, rudder section design, maneuvering performance examination method, etc were analyzed theoretically. Secondly, the design process of rudder device was divided into concept design, initial design and detail design. In concept design, a rudder area was estimated and its validity was examined. In initial design, rudder profile and design method has been selected through rudder form determination process. And principal dimension and steering gear capacity were determined. Maneuvering performance was also examined by simulation tool. In detail design, design criteria considered in rudder initial design has been investigated thoroughly. Also a rudder torque, rudder cavitation performance and rudder structure analysis were estimated. And maneuvering performance was also examined by model test. Finally, based on the results of investigation, the design process of rudder device was generalized and proposed.

As one of recent issues in the information and communication industry, internet of things has attracted attention to provide intelligent infrastructure services which connect and share data and information between real and virtual world. According to the development of these internet of things technologies, types of machines, telecommunication devices, and terminals are increasing tremendously. In this situation, connectivity and interoperability between internet of things components are important issues to build a hyper connected society. To visualize this society, it is important to set up and develop information and communication technology (ICT) standards among stakeholders. However, under limited budget and human resources, it is essential to rank standardization work items for setting standards with respect to efficiency. The purpose of this study is to provide a method for setting standardization strategies within group decision making. As a multi-criteria group decision making tool, analytic hierarchy process (AHP) is adopted and applied to determine the priorities of setting work items. The proposed method first defines decision making problem with objective, criteria, and alternatives which produces a hierarchy consisting of upper and lower criteria. Then, pairwise comparisons of academy and public sector experts are performed with respect to their relative meaning and importance. Individual surveys of expert groups are collected and summarized to determine relative criteria importance measures. Furthermore, to deliver reliable importance criteria measures, differences between academy and public sector expert groups are compared and tested using Mann-Whitney non-parametric test. The results are illustrated for useful guidelines to practical group decision making in standardization strategy establishments.

Rock mass classification systems such as RMR and Q system have been widely served as a simple empirical approach for the design of various rock mass structures in the stage of site survey as well as under the construction. For the RQD determination, the boring is partially carried out and what is more, the survey boring is not normally carried out under construction. Therefore RQD is frequently determined by empirical method or indirect method. Since it is difficult to determine the discontinuity characteristics such as RQD, spacing, persistence, filling and so on, it is essential to develop suitable and simple systems without drilled core and a cert 없 n number of representative parameters. One of the primary objectives of the classification systems for a practicing engineer has been to make it simple to use as a preliminary design tool for the structures in rock mass. In the present study, the modifications for both the RMR and GSI system are suggested by authors to introduce new classification system as well as to improve the scope of some of the existing classification systems for a practicing engineer.

Draw-bead is applied to control the material flow in a stamping process and improve the product quality by controlling the draw-bead restraining force (DBRF). Actual die design depends mostly on the trial-and-error method without calculating the optimum DBRF. Die design with the predicted value of DBRF can be utilized at the tryout stage effectively reducing the cost of the product development. For the prediction of DBRF, a simulation-based prediction model of the circular draw-bead is developed using the Box-Behnken design with selected shape parameters such as the bead height, the shoulder radius and the sheet thickness. The value of DBRF obtained from each design case by analysis is approximated by a second order regression equation. This equation can be utilized to the calculation of the restraining force and the determination of the draw-bead shape as a prediction model. For the evaluation of the prediction model, the optimum design of DBRF in sheet metal forming is carried out using response surface methodology. The suitable type of the draw-bead is suggested based on the optimum values of DBRF. The prediction model of the circular draw-bead proposes the design method of the draw-bead shape. The present procedure provides a guideline in the tool design stage for sheet metal forming to reduce the cost of the product development.

Generic HACCP models for bakery products may help HACCP implementation at the wholesale bakery production lines easier. When baking, the internal temperature of bakery products went up to $85^{\circ}C$, which resulted in gelatinization of starch. Considering the characteristics of bakery products, general sanitation control procedures are the main target tool to keep bakery products safe. Monitoring of pathogenic microorganisms at bakery plant environment including production lines was carried out. At the wholesale bakery environment pathogenic microorganisms were detected. It gave a clue that general sanitation control procedures should be implemented for safe bakery products supply. Hazard analysis of raw materials and processing of bakery products, and determination of critical control points and critical limits at the wholesale bakeries lead to present generic model of bakery product HACCP plan. CCPs for the wholesale bakery products may be applied and modified for the implementation of HACCP plan at the wholesale bakery plant.
