In this paper, I illustrate the some examples of socio-economic influence of railroad in Korea. The Korean railroad has been running for 109 years now since it started operation in 1899. The opening of railroad in Korea has been affecting influence in our society not only transportation but also infrastructure building and the formation of new cities which they were built along the rail network like Daejeon. I have come up with some examples, which railroad has affected the in our society. For example, the changes of transport route from road to railroad, emerging the new cities, industries and culture. This paper contributes to look over the various function of railroad in Korea. Moreover it will be compared with Japan's railroad influence in his country. It gives us a peculiarity and universality in railroad's function including colonial policy

Recently, The business environment is very rapidly changed and complicated. Therefore, the companies are confront with the biggest difficulty. To overcome this difficulty, the management should be able to accomplish the human resources management and the efficient business management. Korea railroad industry has a close association with national life as it carries out public works based on its public nature as well as purses the corporate spirit. For that reason, Korea railroad industry has a great spin-off on national economy and exerts a tremendous impact on the improvement of productivity around the industries and the international competitiveness at aspect of efficiency resulting from business rationalization. Railroad system can be described as organic. Railroad Employs take a great role in this system. According the psychology and the Organization Behavior, the decision maker's personality and employee' work satisfaction have influence on performance. The purpose of this study is to examine the Railroad Employs' Personality and Work satisfaction which influence on the efficient business management.

Several possibilities on the stability analysis of the railroad tunnels passing through the abandoned mining area are considered in this paper. Previous works on the influence zone due to cavities are investigated to study the effect of the safety deterioration near the cavities which are normally unknown to the engineers. Additional works on the numerical analysis of the influential zone are also performed in 3D space. The praximity of railroad tunnel and unexpected cavities is critical to influence the stability of railroad tunnel under construction. Futhermore, the study on the influence of underground condition like joint and faults should be significantly controlled under both design and construction stage.

In this Paper, Ⅰ illustrate the continuity and severance of Korean railroad. The Korean railroad has been running for 105 years now since it started operation in 1899. Between 1905 and 1945, Japan's imperial government ruled Korea including operations of the railroad. After Korea restored its sovereignty, Korean nationals managed the Korean railroad with our own ability and strategies. At present, we can examine the effect of railroad in perspective of continuity and severance respectively. For one thing, the concept of continuity is described as influence or railroad still remains. For another, the severance shows facts and phenomena that are broken off. I have come up with some facts that are involved with continuity. For example, infrastructure and the formation of cities and land spaces are connected with the sequence. Futhermore, the railroad has made a huge dent in modernization and expedition of movement. In the course of tracing down the facts, I classified the concept of severance : the separation of South and North Korea, drastic changes in transport policy, operations and characteristics. Finally technology has brought about a major breakthrough with the development of Koran high speed rail.

Demand forecasting for railroad traffic is fairly important to establish future policy and plan. The future demand of railroad traffic can be predicted by analyzing the demand of air, marine and bus traffic which influence the demand of railroad traffic. In this study, forecasting the demand of railroad traffic is implemented through neural network using the demand of air, marine and bus traffic. Estimate accuracy of the demand of railroad traffic was shown about 84% through neural net model proposed.

Stability analyses on the 17 railroad cut-off soil slopes were carried out. The influences of rainfall infiltration on the slope stabilities were taken into account by seepage analyses using finite element method and by assuming ground water tables to be located adjacent to soil surface. The validity of those analyses were evaluated by comparing the slope failure characteristics between analysis results and the past failure records. The analyses were not appropriate to estimate the failure surface and the method considering only the increase of pore-water pressure (reduction of matric suction) as the influence of rainfall cannot appropriately estimate the surficial failures that occurred most of the cut-off soil slopes. For the better estimation of the surficial failure, the influence of water flows over slope surface which erode soil mass and/or increase driving force, should be evaluated and considered.

There are various elements that have influence on safety and reliability of high-speed railway vehicles. Among them, mechanical characteristics of traction motors are very important. Therefore, we verified that temperature characteristics have influence on damage and durability of these parts. We designed a measurement system for temperature test, and could measure the temperature of each device by the system. As the result of temperature test, we could confirm that the traction motors on Korean High-Speed Train satisfy the criteria. From this test, we get information of the traction motor about the temperature characteristic during running speed and running time.

To overcome this difficulty, the management should be able to accomplish the human resources management and the efficient business management. KR(Korea Railroad) has a close association with national life as it carries out public works based on its public nature as well as purses the corporate spirit. For that reason, KR has a great spin-off on national economy and exerts a tremendous impact on the improvement of productivity around the industries and the international competitiveness at aspect of efficiency resulting from business rationalization. Railroad system can be described as organic. Railroad Experts take a great role in this system.

If the Seoul-Pusan high-speed rail project is able to open its revenue service in 2004, Korea will be the fifth country with an HSR system in the world. And, it will be recorded as a major milestone in the transportation history of Korea. But, Government regulated railroad fare because railroad fare increase can bring negative influences to CPI(Consumer Price Index). Consequently, Korea National Railroad cannot afford to operate railroad independently under current railroad fare system. In this paper, we studied the railroad fare system under implementation and its influences to CPI. And then we proposed that railroad fare must be decided by competition with other transportation modes and based on the demand variance by introducing YMS(Yield Management System).
