The railway industry is constrained by barriers within itself, which prevent it from competing effectively with other means of transportation, particularly road transportation. Therefore, many countries have adopted the policies that aim to remove barriers to providing international transport services by creating a common framework for railway industry. Recently, the European Union has produced the European Interoperability Directives, which aim to remove the technical problems involved in running trains between member states. In this respect, it is important to harmonize the technical requirements and specifications of Korea railway industry. This paper presents an action plan for the advancement of railway technical specifications in Korea. For this, the railway law and regulations of other countries are reviewed. Also the technical problems and operational barriers of railway industry are analyzed in Korea. This will help transportation agencies to resolve the technical problems of criteria in Korea railway industry.

Automatic Operation based on ATO (Automatic Train Operation) is necessary for driverless Light Rail Transit business. When this kind of driverless LRT operation plan is made, TPS (Train Performance Simulation) is traditionally simulated at all-out mode and coasting mode based on manual operation. Commercial schedule speed equals to all-out speed minus $9{\sim}15%$ make-up margin. Coasting mode TPS simulation is also run at commercial schedule speed to calculate run time and energy consumption. But TPS based on manual operation should make an improvement on accuracy in case of driverless LRT operation Plan. In this paper, new fast mode TPS simulation using ATO pattern is proposed and show near actual ATO result. The actual ATO pattern can be accurately simulated with the introduction of 4 parameters such as commercial braking rate, jerk, station stop profile and grade converted distance. Normal mode TPS simulation for commercial schedule speed can be designed to have fast mode trip time plus 3 seconds/km margin recommended by korean standard LRT specification.

As facing the challenges from many competitors, the Office of Korea Postal Service has issued the fundamental plan of business renovation which includes the master plan of the information systems. In this paper we discuss the design of a to-be information system for postal service, which will be provided for the completion of the master plan. After briefly discussing the issues on developing information system and the current situation, we provide the design concept and the framework of the to-be system based on the bench marking and gap analysis with advanced systems. The to-be system consists of eight subsystems which can be grouped into three categories; intelligent systems, operational systems, and platforms. We develop detailed specification of each subsystem and provide an operational scenario. We also explain how the to-be system compatibly fits into an integrated information system, which will include the postal, banking, and management functions, to perform its ultimate role for the efficient postal service.

A demand of marine outfall system has been much increased for the effective disposal of the wastewater due to population and industrial development at the coastal areas. The outfall system discharges primary or secondary treated effluent into the coastline, or at the deep water, or between these two. The discharge is carried out by constructing a pipeline on the sea bed with a diffuser or with a tunnel, risers and appropriate. The effluent, which has a density similar to that of fresh water, rises to the sea surface forming plume or jet, together with entraining the surrounding salt water and becomes very dilute. Thus there have been growing interests about plume behaviour around the outfall system. Plume or jet discharged from single-port or multi-port diffuser might cause certain impacts on coastal environment. Near field mixing characteristics of discharged water field using CORMIX model have been studied for effective outfall design various conditions on ambient current, depth, flow rate, effluent concentration, diffuser specification, port specification etc.. This kind of analysis is necessary to deal with water quality problems caused by the ocean discharge. The analyzed result was applied to the Pusan Jungang effluent outfall system plan.
