최근 정보통신 생태계는 스마트 기기의 대중화와 대용량 데이터 스트리밍을 필요로 하는 다양한 인터넷 서비스들의 출현과 함께 인터넷 및 모바일 데이터 트래픽이 급속도로 증가하게 되었다. 이에 따라 원활한 인터넷 접속문제, 네트워크의 혼잡 및 정체, 그리고 통신사업자들의 지속적인 네트워크 투자 비용증대 등 다양한 문제들이 초래되었다. 이렇게 데이터 중심의 패러다임으로 변화된 통신 생태계 속에서 초기 상호접속체제들은 사업자들 간 균형 있는 혜택과 공정한 분배 그리고 차세대 네트워크 구축을 위한 경제적 유인을 형성할 수 없다는 측면에서 논란이 가중되고 있다. 따라서 더욱 복잡해진 All-IP 네트워크 환경에 부합할 수 있는 진화된 인터넷 상호접속체제의 도입이 필요한 상황이다. 이에 본 연구에서는 국내 인터넷 상호접속제도의 핵심이슈를 발굴하고 인터넷 초기에서 현재까지의 인터넷 상호접속체제를 전반적으로 분석한 후, 실증연구를 통하여 트래픽 최적화, 비용 최적화, 네트워크 투자 최적화의 세 가지 측면에 부합될 수 있는 인터넷 상호접속체제를 제시하고자 한다.

Since 'The Act on Private Investment of The Infrastructure' was established in 1994, private investment as well as government's investment has been active on transport infrastructure. But investment of transport infrastructure has more risks than others due to overforecast of transport demand for ensuring project validity, and cost uncertainty arising from financial crisis, commodity prices and so on. In the case of Incheon international airport express, after 2 years and 6 months, Incheon international airport express is opened, Korail take over equity stake in private investor due to the problems of MRG(Minimum Revenue Guarantee) be contracted with private investor. Not only that, in other case of Yong-in light rail, it is ongoing for legal disputes between Yong-in local government and private investor on account of opening delaying. On current Investment Assessment System of Transport Infrastructure, Risk Management system on investment of transport infrastructure is inadequate because Sensitivity Analysis in economic efficiency have been performed on the simple method which only changes benefits, expense and social discount rate. For this reason, this study analyze risks for investment of transport infrastructure demand forecast, and rise to the management practice for every particular item.

Vietnam is gaining much attention as an attractive emerging market that can replace BRICs for the corporations who are destined to always look for a new market in order to secure competitive powers in the global market. The reason for Vietnam's becoming an attractive place for production is that much uncertainty has been found in China, which has been the traditional country that absorbed the most amount of capital investment. Also, the favorable conditions of Vietnam market itself and the environmental changes such as the open-door policy of Vietnam government attract the investment of Korean companies, and Korea currently holds the most amount of cumulative investments in Vietnam. However, it is necessary to remember that Vietnam is still a socialist nation, and many required components for corporate activities are not sufficiently provided in Vietnam market. Also, many unstable environmental factors exist such as the lack of infrastructure, the lack of many required institutions, the prevalent corruption, the excessive processing time and cost for adjusting the investment, the lack of advanced work force, and the underdevelopment of part and material industry. Therefore, those companies who are planning to invest in Vietnam should take a long-term perspective in planning the investment strategies, carry out a detailed market investigation and analysis in advance, diversify the investment areas and investment sectors, carefully make a joint venture and management, carefully determine the factory location, establish a local agency, make co-investments with the part suppliers, etc.

The main objectives were to investigate the suitability of CaO crucible for melting TiAl alloys and to develop investment mold for investment casting of TiAl alloys. TiAl alloy specimen were prepared by plasma arc furnace under argon atmosphere. After melting of TiAl alloy using CaO crucible, the results showed that there is little contamination of oxygen in the TiAl bulk. Conventional vacuum induction furnaces can be readily adaptable to produce cast parts of TiAl without high skilled techniques. The determination of optical metallography and microhardness profiles in investment cast TiAl alloy rods has allowed the gradation of the relative thermal stability of the oxides examined. The molds used for the present study were $ZrO_2$, $Al_2O_3$, CaO stabilized $ZrO_2$ and $ZrSiO_4$. Even although high temperature of mold preheating, $Al_2O_3$ mold is a promising mold material for investment casting of TiAl alloys in terms of thermal stability, cost and handling strength. It is important to take thermal stability and preheating temperature of mold into consideration for investment casting of TiAl alloys.

With the rapid development of the Fourth Industrial Revolution and digital transformation, scientific and technological innovation measures are being devised to overcome Korea's low-growth, high-cost structure. Accordingly, by examining the R&D investment evaluation system of R&D PIE (R&D Platform for Investment and Evaluation), which has been promoted by the Korean government in response to the Fourth Industrial Revolution, from the perspective of R&D transformation, this study aims to explore a new path for a sustainable national science and technology innovation system following digital transformation. In particular, from the perspective of R&D PIE, a MLP (Multi-level Perspective), which had been conducted as an abstract theoretical study, was attempted with specific cases and analysis for each of the three layers: niche, landscape, and regime. In conclusion, R&D PIE was intended to elevate the abstract R&D investment evaluation system to a platform that leads innovation in the digital space of the Fourth Industrial Revolution. In addition, it was confirmed that the R&D PIE could be replaced or enhanced as a platform for innovation in response to the Fourth Industrial Revolution, thereby providing an alternative to job creation and an escape from economic crisis.

Investor-State Dispute Settlement(ISDS) grants a foreign investor the right to access an international arbitrator, if he believes actions taken by a host government are in breach of commitments made in an investment agreement or an investment treaty. The arbitration procedure of ICSID is made specifically to resolve investment disputes, so most of investment disputes have been settled in accordance with the procedure. Owing to limitation of dispute settlements through the ICSID arbitration procedure, several investment dispute conciliation schemes have been emerged as alternatives. In the case of a conciliation, the conciliation procedure will be in progress based on arbitrary agreement between parties, and if both parties agree on a conciliation program, then the arbitrary execution rate is relatively higher than that of arbitration procedures. In addition, it is evaluated that the time duration of conducting a conciliation procedure is in general rather short in 8 to 24months, and its incumbent cost is also rather inexpensive. Most of all, through amicable settlement of a dispute between a foreign investor and a host state, the foreign investor may continue his investment activities without a hitch, while the host state may invite more investment without any risk of losing its external credibility. In conclusion, it is desirable to lead any investment dispute between a foreign investor and a host state settle in accordance with the dispute settlement procedure as specified in the relevant investment agreement. In addition, to make the foreign investor continue his investment activities, it will be necessary to provide a separate investment dispute conciliation system aside from such arbitration procedures to cope any unexpected incident flexibly.

It has regarded an attempt to design and construct more safe structures as challenges such as fate. In order to operate public facilities safely, It can be taken how to improve the resistance to applied load by increasing the cross-section of structural members or by installing reinforcement. But inevitably such a way is accompanied by an increase of construction cost or maintenance cost. To make a cost-effective construction, Reliability-based decision analysis which can judge the adequacy of investment is suggested using statistical data of the load, resistance and the maintenance cost.
