The development of the TSR-TKR Network will be regarded as the most important step towards the realization of integrated regional transportation system. If the TSR-TKR is constructed, there may be a possibility for the TKR to be used for shipments to Europe relacing marine shipments that take place at present. However, major forwarders think that it will not be easy to ensure the economic competitiveness of the TSR-TKR route. In this study, we have analyzed the optimim route for integration of opreation line on TSR-TKR.

Purpose: The purpose of this study is to analyze the economic ripple effect(ERE) of logistics industry by construction of Trans-Korea Railway (TKR) and present policy measures to minimize the economic loss of South Korea (SK). Research design, data and methodology: As the analysis method, exponential smoothing was used for demand forecasting, Input-Output analysis was used to estimate the economic ripple effect coefficient, and scenario analysis was used to an efficient way to invest in TKR to minimize SK's economic losses. Results: 1) the production(logistics fares) of TKR for 10 years after its completion is about 11.42 trillion won in positive relations, and 26.89 billion won in negative relations. 2) the ERE of SK in positive relations is 24.32 trillion won in production inducement effect, 8.1 trillion won in value-added inducement effect, 3.54 trillion won in import inducement effect, and 70,930 persons in employment inducement effect. But the ERE was insufficient in the negative relations. 3) SK's efficient investment method is providing materials and equipment by SK and building the TKR by North Korea in positive inter-Korea relations. Conclusions: For the successful operation of TKR, international cooperation, legalization and stable peace settlement on the Korean Peninsula are required.

우리나라의 주요 교역권은 아시아, 미주, 유럽 교역권으로 나눌 수 있다. 일반적으로 대량의 화물운송은 해상운송이 주를 이루지만 다른 지역과 다르게 유럽 교역권은 철도 운송이 가능하다. 또한, 중국의 성장으로 동북아 물류 중심지로서의 경쟁력이 약화된 우리나라는 지금의 경쟁구조와는 다른 방안인 철도운송에 주목할 필요가 있다. 이러한 배경 하에 본 연구에서는 한반도 종단 철도(TKR)와 시베리아 횡단철도(TSR)를 이용한 유럽 지역과의 운송 경로를 비교하여 경제성 분석에 주안점을 두었다. 분석의 요소로는 운송거리, 운송기간, 운송비, 추가비용을 중심으로 사용하였으며 분석 결과 6가지의 운송경로 중에서 TKR과 연계한 TSR(Route 1)이 경제적이라는 분석 결과가 나왔다. 따라서 향후 러시아 푸틴정부의 극동발전 전략에 대비하여 우리나라는 TKR과 TSR의 철도운송을 활용하는 것이 국가 경쟁력을 높일 수 있는 방안이 될 것이다.

Nowadays, road transportation which has played a key role in the market of both passenger and freight transportation is facing with a serious problem, the traffic congestion causing a delay of transportation. Therefore, railroad transportation is considered as an attractive alternative mode of inland transportation due to its inherent merits in mass transportation such as relatively low cost compared with road transportations, less air pollution and noise than other mode ets. In this paper, therefore, we examine the current situation of railroad transportation markets including TKR(Trans- Korean Railway}, TSR(Trans-Siberian Railway} and prospects for the connection of TKR-TSR. And then we examine the structure of the container transportation market by railroad in Korea with a brief analysis of the traffic volume of TKR-TSR.

PURPOSE: The Western Ontario and McMaster Universities Arthritis (WOMAC) index has been used to measure the outcome of total knee replacement (TKR), but studies on its reliability and validity are limited. The present study examined the reliability and validity of this index for patients with knee osteoarthritis who underwent TKR. METHODS: Seventy-one inpatients and outpatients who underwent bilateral TKR for knee osteoarthritis were included in this study. The pain assessment scale and WOMAC index were used to evaluate the participants every two weeks to examine the test-retest reliability, internal consistency, and construct validity. RESULTS: The test-retest reliability scores for pain, stiffness, and physical function were .75-.92, .85-.90, and .75-.95, respectively. The corresponding intraclass correlation coefficients were .75-.88, .76-.88, and .71-.95, respectively. The internal consistency score in the first and second examinations was .92. Furthermore, the construct validity scores for pain, stiffness, and physical function were .83, .41, and .58, respectively. CONCLUSION: The application of the WOMAC index in patients who underwent TKR showed high test-retest reliability and internal consistency with the use of the WOMAC index and good validity with the use of the pain assessment scale.

In this study, the effect of stem-end design on contact pressure and stress distribution in revision TKR was investigated using finite element method. The finite element model of tibia, including the cortical bone, the cancellous bone and canal, was developed based on CT images. The implant models with various stem lengths, diameters, friction coefficients, and press-fit effects were considered. The results showed that the longer stem length, the stronger press-fit, the bigger stem diameter, and the higher friction coefficient increased both peak contact pressure and Von-Mises stress distributions. The results supported the clinical hypothesis that peak contact pressure and stress are related to the stem end pain. The results of this study will be useful to design the stem and reduce the end-of-stem pain in revision TKR.

우리나라의 주요 교역권은 아시아, 미주, 유럽 지역권으로 나눌 수 있다. 아시아, 미주 지역권은 해상 운송이 주를 이루지만 유럽 지역권은 해상 운송 뿐 아니라 철도 운송이 가능하다. 유럽 지역권 또한 해상운송이 많은 부분을 차지하고 있지만 철도 운송을 이용한 운송도 꾸준한 증가를 보이고 있다. 본 연구에서는 유럽 지역과의 교역에서 활용 가능한 운송 경로를 비교하여 경제성 분석에 주안점을 두었다. 분석의 요소로는 운송거리, 운송기간, 운송비를 중심으로 사용하였다.. 분석 결과 TKR과 연계한 TSR이 경제적이라는 분석 결과가 나왔지만 러시아의 물류 환경이 우리가 알고 있는 일반적인 지식과는 많은 차이가 있어 해결과제들이 존재하고 있다. 이러한 문제들의 개선사항이 해결된다면 TSR은 철의 실크로드 시대를 열 수 있으며 TKR의 시작점인 우리나라는 경제적 파급 효과는 물론 동북아 물류 거점으로 입지를 확고히 해나 갈 수 있다.

The goal of total knee replacement (TKR) surgery is to replace patient's knee joint with artificial implants in order to restore normal knee joint functions. Since mismatched knee implants often cause a critical balancing problem and short durability, designing a well-fitted implant to a patient's knee joint is essential to improve surgical outcomes. We developed a software system that three-dimensionally (3D) simulates TKR surgery based upon 3D knee models reconstructed from computed tomography (CT) imaging. The main task of the system was to extract precise 3D anatomical parameters of a patient's knee that were directly used to determine a custom fit implant and to virtually perform TKR surgery. The virtual surgery was simulated by amputating a 3D knee model and positioning the determined implant components on the amputated knee. The test result shows that it is applicable to derive surgical parameters, determine individualized implant components, rehearse the whole surgical procedure, and train medical staff or students for actual TKR surgery. The feasibility and verification of the proposed system is described with examples.

The stem models with various stem lengths, diameters and frictional coefficients, and press-fit effects were considered. The results showed that the longer stem length, the stronger press-fit, the bigger stem diameter, and the higher frictional coefficient increased both peak contact pressure and the highest Von-Mises stress values. We hypothesized that peak contact pressure and Von-Mises stress distribution around the stem, may be related to the stem end pain. The results of this study will be useful to design the stem endand reduce the end-of-stem pain in revision TKR.

The objective of this study is to propose a Korean medical rehabilitation protocol for total knee replacement (TKR) and to report its effectiveness. This study was conducted as a retrospective study which analyzes the medical records of 4 patients undergoing Korean medical rehabilitation with protocol and continuous passive motion exercise for more than two weeks after TKR. We evaluated the outcome checking physical examination findings of the knee joint, numeric rating scale (NRS), Lysholm knee score (LKS) and walking state. After the treatment, we observed that the function of knee joint, NRS, LKS, walking state of patients were improved. This study showed that Korean medical rehabilitation protocol has effect on knee joint recovery after TKR. The limitation of this study was the insufficient number of cases and short-term follow up. Further studies should be done steadily to report the effectiveness of a Korean Medical rehabilitation protocol for TKR.
