The subsystems of HSR train control system in each country has developed and operated till early 2000, however 2001/16/EC ERTMS is issued for inter-operability among European train control systems in 2001. So it is trend that ERTMS/ETCS has been applied to not only low-speed train system but high-speed train system over 300km/h in many countries of Europe. According to the government policies of the Honam HSR, metropolitan HSR and test lines, incoming on-board signal control system has been required caused by speed limit to 160km/h on the ground signal system. As ETCS-Level 1 system has applied in our railways from 2003, so our train control system has depended on foreign technologies. In this paper, we analyzed to localize train control system for being ready to protect foreign policies and obtaining core technologies of HSR train control system for instance ETCS-Level2.

An intelligent robot, which has been developed recently, is no more a conventional robot widely known as an industrial robot. It is a computer system embedded in a machine and utilizes the machine as a medium not only for the communication between the human and the computer but also for the physical interaction among the human, the computer and their environment. Recent advances in computer technology have made it possible to create several of new types of human-computer interaction which are realized by utilizing intelligent machines. There is a continuing need for better understanding of how to design human/robot interface(HRI) to make for a more natural and efficient flow of information and feedback between robot systems and their users in both directions. In this paper, we explain the concept and the scope of HRI and review the current research trends of domestic and foreign HRL. The recommended research directions in the near future are also discussed based upon a comparative study of domestic and foreign HRI technology.

The recent trend in the payment terms of international trade shows the gradual shift toward more diversified payment methods (from L/C to not L/C) in order to cope with the increasingly dynamic international transactions in a more flexible manner. The reasons behind this recent shift are as follows : first, the global trade market is breaking away from the traditional L/C methods based on letters of credit toward a not L/C methods. nother reason for the changing trade payment methods is the increasing volume of intra transactions between headquarters and their foreign subsidiaries based on collection payment methods. Having mentioned the above problems that impede the Korean export insurance system, some suggestions can be put forward through a comparative analysis with foreign export insurance system. First, inducing private investments is one way of strengthening financial health of the KEIC. The KEIC also needs to diversify its insurance coverage adapting to the changing international trade environments.

국내상황을 볼 때 수입화장품의 점유율 상승으로 인해 국내시장 잠식이 확대되고 있으며, 기능성 화장품의 성장 가능성에 대한 제도적 뒷받침이 미비하고, 천연소재를 사용한 고기능성 화장품 시장규모가 확대 추세에 있다. 외부적 환경으로는 무역역조가 심화되는 추세이며 해외 수출기반이 취약한 상태이어서 제외국과 비교하여 기능성 화장품 개발 촉진을 위한 제도가 미비한 상태이다. 따라서 화장품 산업의 진흥을 위하여 기본방향으로 고품질 신제품 개발을 촉진하고, 세계 시장으로의 수출을 확대하며 화장품법령의 합리적 개선을 추구하여야 한다.

This study intends to analyze the trade competitiveness of Korean films in international markets. Under environmental of film industry, Korean films could be doing better. But the Key success factors Korean films in the foreign markets are the improvement of contents Quality and the diversification of trade market. Namely, Our films is mainly exporting Japanese market and the import depends upon American films. In case the trade specialization index(TSI), The international competitiveness of Korean films shows lower import specialization, by virtue of export increasing of Japan, Europe and other markets in 2000's. On the other hand, The Export Market Share has shown similar pattern to main markets except Japanese market, and the import was almost similar to trend in foreign markets except American films. Consequently the present film strategies and polices that delight limited markets will not be compete in global markets, Korean films or contents is merely called by that name.

This study is on the alcohol beverage utensils represented on the Chinese tomb mural paintings of Song, Liao, Jin, and Yuan those countries had foreign exchange with Koryo Dynasty. These mural paintings are distributed in the areas such as Hebei, Henan, Inner mongolia, Shanxi, Shaanxi, Peijing. etc. The Alcohol beverage vessels were classified mainly into storage vessel, pouring vessel, drinking vessel and ladles according to the purpose. The storage vessels of Song, Liao and Jin were called Jiuping, Jingping, Jiuzun as well as Meiping. Pouring vessels are basically one set of Zhuzi, Wenwan and Jiuzhu, or Zhuhu and Zhuwan. On the mural paintings of Yuan Dynasty, Meiping as storage vessels disappear, and a variety of shapes of pouring vessels such as Mayu and Yuhuchunping appear. This trend indirectly indicates the new arrival of distilled liquor, which seems to have affected transition of the alcohol beverage utensils.

This paper presents at the characteristics of publications in the Journal of Astronomy and Space Sciences from 1984 to 2018. Since its first publication, a total of 1,113 papers (~35 volumes) have been published up to December 2018. While the space astronomy field has made up a large portion of the total number of papers, the number of annually published papers in this field is decreasing. In contrast, the number of papers in the space environment field has been showing an increasing trend since 2013, accounting for more than 30% of the annual publications. The participation rate of foreign researchers has been maintained at greater than 20% since 2012. Despite the decrease in the number of paper per year, there are positive developments including sustained foreign researcher participation at greater than 20% and improvements in the impact factor. We believe that JASS has the potential to enter the distinguished level of international academic journals following a well-developed future road map.

In this study, the actual states and cases utilizing lake dykes were investigated focusing on large-scale reclamation project in domestic and instances in advanced foreign countries. The attitudes investigation concerning lake dykes utilization was performed to residents in-and-around Saemangeum. According to the research result, in domestic the utilization of lake dyke have not attracted attention because maximizing land use, which was the primary purpose of reclamation project at the early stage, has been emphasized so far. The advanced foreign countries, however, not only make use of farmland, but also develop activities employing lake dykes. According to the result of an analysis for local residents' attitudes, they want to be used Saemangeum lake dykes as a multifunctionality facilities performing a role of environment friendly equipment as well as a breakwater. They also require further investigation and to be introduced new system far utilizing as a multifunctionality facilities. Recently, green tourism is getting attention more and more owing to laying stress on balanced development of country and improvement on life quality of rural residents and launching five days in duty. It is believed that on this favorable trend lake dykes an be employed as a primary tourism resource if its utilization is developed actively.

현재까지 국내에서는 적외선 관측위성을 보유하고 있지 않으나 해외에서는 다양한 형태의 적외선 관측위성이 개발되어 운용중이다. 본 논문에서는 적외선의 일반적인 특성과 이에 따른 영상활용의 방안을 분석하였다. 아울러 적외선 관측위성의 해외 개발현황을 주요 위성 사례별로 조사하여 소개하였다. 해외의 경우 산불감시, 화산활동 연구, 해수면 온도 측정, 지표면 온도 측정, 기후변화 연구, 환경 감시 등 다양한 분야에서 적외선 영상이 활용되고 있다. 국내도 이러한 추세에 맞게 저궤도 적외선 관측위성의 개발을 추진해야 할 것이다.

The city means not only a geographical area as a role of the spatial boundary, but also a socio-economic place to communicate with each part. It requires various functions to get the income and activities. But city has a limitation of a available land to provide the required function and a sufficient space to supply the activity. Therefore, the development trend of city has not been to spread to the horizontal area any more and considered the vertical area. In addition, various functions put into a massive building because many people want to solve the daily requirements without spending time and cost. In this paper, it aimed at classifying the mixed-use building into function, circulation, relation between the public and private space and the building shape to provide the design information according to the development constraints such as land area, functional limitation, accessibility, etc. The classification of the mixed-use buildings is divided into four areas. The data are collected with foreign countries in Japan, Europe and US.
