Varied opinions have been raised on Sushen's regional activities. These are Hwabuk drift theory, Shandong Peninsula drift theory, Liaotung Peninsula theory and the theory of Eastern Area in Heilongjiang Province. The theory of Sushen Dongbei that Sushen's regional activities are the Eastern Area in Heilongjiang Province is widely accepted in the chinese academia. However, this paper try to criticize the theory of Sushen Dongbei on the basis of archeological data. Prehistoric monuments of the Eastern Area in Heilongjiang Province are Singaeryu remains, Sonamsan remains, Aenggaryeong remains, Seokhoejang remains, Jinheung remains and Aporyeok remains. Residential group in the Eastern Area of Heilongjiang Province lived the economic life of fishing and hunting and were involved with primitive agriculture only in partial area. Its society was patriarchal clan steps of phallocentrism. By considering the cultural exchange between the Eastern Area in Heilongjiang Province and Chinese dynasty, the aspect of cultural exchange in two areas was unascertainable. Therefore, the theory of Sushen Dongbei is a mistake in Chenshou's "Sanguozhi" and nothing but a theory that base on the unified theory of Zhonghua minzu and the nationalistic intention in China.

Due to the development of the domestic economy and science, the people's standard of living has increased. Accordingly, we want to improve the quality of life. In other words, we guarantee human rights and pursue dignity and value as human beings. Therefore, the medical field extends human life and helps maintain a healthy life. The social medicine that protects human rights is forensic medicine. Forensic medicine identifies deaths and analyzes the cause using forensic radiology images. Forensic radiology is the acquisition and provision of medical images by the radiographer. Therefore, the radiographer must have expertise by completing forensic science-related courses. Recently, medical and nursing schools have opened and operated various subjects such as forensic medicine and forensic nursing. However, the Department of Radiology science is the only school that offers courses related to forensic science. For the future development and exploration of the radiographer and department of radiology science, forensic education should be considered. For this purpose, we investigated the necessity and demand for forensic education in the department of radiology science undergraduate and graduate schools. The department of radiology science students' awareness of forensic science was found to be 2.977 points, but the need for forensic science education for the radiographer was high at 3.759 points. In addition, current students' demand for forensic science courses was high at 84.1%, with the majority responding that it was necessary to open and operate the course. This study was able to determine the demand for forensic science-related subjects among the department of radiology science undergraduate and graduate students, and there is a need to explore diversity and expertise in education. We hope that it will be used as basic data for the development of forensic medicine and radiology science.

글로벌 금융위기 이후 우리나라의 조선사와 해운사의 경영악화가 심화되고 있다. 해양플랜트 시장의 성장에 맞춰 OSV의 성장도 두드러지는 실정이지만, 우리나라의 조선사와 해운사의 진출은 아직 초보단계에 머물러 있다. OSV는 우리나라의 경제성장의 한 축을 담당했던 조선-해운의 동반성장 모델과 마찬가지로 OSV건조-운영은 침체에 빠져있는 우리나라 조선사와 해운사에 좋은 성장기회를 제공하여 동반성장이 가능한 좋은 전략이 될 수 있을 것이다. 이에 본 원고에서는 국내 조선사와 해운사가 OSV 시장에 동반진출할 수 있는 방안을 제시하였다.

In order to improve the productivity and continuous competitiveness of container terminals, it is necessary to make efforts to reduce operational losses at each terminal. As a study on this, it is necessary to study the non-productivity movement based on the shuffle(re-handling) in the yard analysis is needed. In this study, non - productive activity factors were classified by prefecture, transporter, shippers and terminal based on operation data of domestic A terminal. As a result, 14.7% is due to the causes of shipping companies and shipping companies, and in addition, 85.3% of the respondents indicated that they were responsible for the terminal operation. In order to minimize the above factors, it is necessary to reduce the non-productive activity through rapid information processing and pre-information acquisition from shipping companies, and minimize the influence of bulge-out through installation of concrete blocks in the equipment field.

This study looks at the reasons behind the termination of container transportation between Busan and Incheon in terms of costs structure, the division of profit, and the economic limitation faced in the domestic shipping market. The operation costs have been examined in relation to the components of logistic system of container shipping and the cost function has been estimated. The distribution proportion of operation revenue has been also investigated, considering the different components of logistics activities. In addition, the average revenue of container vessels of 144TEU and 215TEU has been calculated. Economic limitation can be analysed through the optimisation behaviour of shipping companies which tries to maximize profit or minimize loss. In conclusion, domestic short sea shipping can get the economy of scale only by transporting vessels' maximum capacity. It is also vulnerable to trucking market's fluctuation. Without the subsidy for operation, the liner in domestic short sea shipping will stop the service in order to minimize the loss.

$\underline{Purpose}$: An analysis of the infrastructure for radiotherapy in Korea was performed to establish a baseline plan in 2006 for future development. $\underline{Materials\;and\;Methods}$: The data were obtained from 61 radiotherapy centers. The survey covered the number of radiotherapy centers, major equipment and personnel. Centers were classified into technical level groups according to the IAEA criteria. $\underline{Results}$: 28,789 new patients were treated with radiation therapy in 2004. There were 104 megavoltage devices in 61 institutions, which included 96 linear accelerators, two Cobalt 60 units, three Tomotherapy units, two Cyberknife units and one proton accelerator in 2006. Thirty-five high dose rate remote after-loading systems and 20 CT-simulators were surveyed. Personnel included 132 radiation oncologists, 50 radiation oncology residents, 64 medical physicists, 130 nurses and 369 radiation therapy technologists. All of the facilities employed treatment-planning computers and simulators, among these thirty-two percent (20 facilities) used a CT-simulator. Sixty-six percent (40 facilities) used a PET/CT scanner, and 35% (22 facilities) had the capacity to implement intensity modulated radiation therapy. Twenty-five facilities (41%) were included in technical level 3 group (having one of intensity modulated radiotherapy, stereotactic radiotherapy or intra-operative radiotherapy system). $\underline{Conclusion}$: Radiation oncology in Korea evolved greatly in both quality and quantity recently and demand for radiotherapy in Korea is increasing steadily. The information in this analysis represents important data to develop the future planning of equipment and human resources.
