  • The current downturn of BIPV sector has an enormous potential to rebound and expand into the PV sector for construction market in the foreseeable future. Solar technology has already gained a significant market due to lack of natural resources in the Korean domestic market. Given the technical infrastructure of state-of-the-art fusion technology, the competitiveness of software-driven BIPV market in the world can be ver attractive and have the potential to develop as a key national technology. To do this, from the viewpoint of complexity, technical R&D, national political aspect, social aspect, economic aspect and institutional support systems need to be parallelly formulated. A dedicated BIPV sector has not yet been established, especially policy and institutional framework have very crucial impact on the establishment of BIPV sector.

  • Safety operation of main pipelines is primarily provided by anticorrosive monitoring. Anticorrosive monitoring of oil pipeline transportation objects is based on results of complex corrosion inspections, analysis of basic data including design data, definition of a corrosion residual rate and diagnostic of general equipment's technical condition. All the abovementioned arrangements are regulated by normative documents. For diagnostics of corrosion-technical condition of oil pipeline transportation objects one presently uses different methods such as in-line inspection using devices with ultrasonic, magnetic or another detector, acoustic-emission diagnostics, electrometric survey, general external corrosion diagnostics and cameral processing of obtained data. Results of a complex of diagnostics give a possibility: $\cdot$ to arrange a pipeline's sectors according to a degree of corrosion danger; $\cdot$ to check up true condition of pipeline's metal; $\cdot$ to estimate technical condition and working ability of a system of anticorrosive protection. However such a control of corrosion technical condition of a main pipeline creates the appearance of estimation of a true degree of protection of an object if values of protective potential with resistive component are taken into consideration only. So in addition to corrosive technical diagnostics one must define a true residual corrosion rate taking into account protective action of electrochemical protection and true protection of a pipeline one must at times. Realized anticorrosive monitoring enables to take a reasonable decision about further operation of objects according to objects' residual life, variation of operation parameters, repair and dismantlement of objects.

  • There is no disagreement that the construction sector will play an important role in inter-Korean economic development cooperation. However, very few studies have been made at North Korea's construction technology. North Korea shows a lot of differences from South Korea, from the quality standards of building materials to construction technology. It is clear that these differences will be a stumbling block to the promotion of construction projects in the inter-Korean cooperation stage. Therefore, the start of inter-Korean economic development cooperation should be preceded by work to clearly recognize each other's differences and lay the foundation for integration or compatibility. The purpose of this study is to compare the construction technology of rebar concrete construction. We compared the differences with Korea's construction method based on the construction books recently published in North Korea, and derived the characteristics of North and South Korea for each detailed process of reinforced concrete construction.

  • For four decades now KEPCO has experienced an incredible growth rate of over 10% per year in each year. This growth led to the fast development of new facilities, especially in the transmission systems field, and we also managed to gain an enormous amount of experience and technology in the construction and design. With this experience and technology we curbed the electricity demand. Experts now predict that we will enter a new phase in which our growth rate will stagnate and eventually level off. This isn't what KEPCO or any company wants. We are looking for continued growth. In the last decade KEPCO began selling its technology in the generation sector of the electricity business to overseas markets. Sales in the generation sector have been a great success. This decade marks another milestone for KEPCO as overseas sales in the transmission sector began. Our first project, "Myanmar Power System Development Study" and its subsequent successful completion gave us the ammunition necessary to expand in this line of business. This success has also given birth to this paper. KEPCO is still the People's company, but with a new vision. It now hopes to not only sustain a high growth level but to also increase the growth of domestic companies by sharing with them a piece of the proverbial pie, as it ventures forth to be a Global player on the international stage.

  • Recent national policy agenda of 'Low-Carbon Green Growth' has been implemented as the important vision of the country. The government has set a target of entering the seven major world powers of Green Nation at 2020, and five major world powers at 2050. In order to achieve the goal, the reduction of greenhouse gases and the composition of green land and transportation has been promoted as an important policy. In a construction industry sector, policies and technologies for reducing greenhouse gas emissions and energy have been actively developed. In the case of developed countries, research for green road infrastructure has been conducted, which is the basis for certification system of green highway. This paper benchmarks the policies and cases of developed countries, verifies the applicability in the domestic road sector, and suggests the introduction of the certification system of green highway.

  • In this study, surveys and interviews are used to evaluate technological competitiveness of each product with respect to that of foreign leading firms, for seven leading domestic construction products which have been determined to have competitive edge in offshore markets, Such evaluation provides a more in depth study than previously conducted research, and is meaningful in that corporate level, rather than industry level, perspective is projected. Major findings of such evaluations are the following. First, as expected, it has been evaluated that domestic technological competitiveness in desalination plant and power plant has reached the point where it can compete with foreign leading firms. Moreover, a noteworthy result of the evaluation is that development program sector, including urban development of satellite cities, has reached considerable level of competitiveness in offshore market. In the case of the development market, domestic firms have accumulated sufficient experience in domestic market and engineering technology is not a decisive factor as in plant sector, and these factors lead to such an evaluation. Second, in the cases of gas, oil refinery and petro-chemical plants, domestic products' technological competitiveness that can contest in offshore market is still centered around production and construction. On the other hand, there are still weaknesses in license technology and basic design capabilities, which constitute the "value added" area. Third, skyscrapers, a promising product in offshore construction market and a product group which domestic firms have much performance record and projects in progress both in domestic and offshore markets, are considered. While direct comparison between skyscrapers and plant sector is not feasible, with the exception of production and construction, overall domestic capability in this sector has been assessed to be the lowest amongst those products that were surveyed. Fourth, it has been indicated that competitiveness is relatively higher in common technology than in key technology. In project management capability, it has been assessed that there are weaknesses in procedure document area. Also, a characteristic is the point that low overall assessments have been given across all product groups for corporate and management areas, not technological areas. Especially, financing, contracting/claim, risk management and investment on research and development received low evaluations. Fifth, it has been assessed that overall corporate and governmental supports are weak. This result is especially evident for corporate management and support areas across all product groups surveyed.

  • The annual expenditure on diesel oil and heavy oil in the construction sector is the second largest among all industrial sectors. According to the greenhouse reduction scheme of Korean Government, construction sector targeted 7.1% reduction by 2020. Although this target is not higher than other industrial sectors, it is not easy to achieve the reduction target without radical advance in technology, which cannot be expected to happen soon, considering the conservative characteristics of construction industry. Most researches on environmental issues focus on the issues related to energy saving matters during material production stage or maintenance stage, such as heating and insulation, and few deal with the issues directly related to the energy use in the construction sites. This research regards the operation of equipment for the on-site construction processes as a system and attempts to model the energy use processes related to the activities in construction sites, and provides simulation results of earth excavation and hauling processes. The result of this research is expected to aid construction planners estimating the time-based patterns of energy use and assessing greenhouse gas emission and to help selecting more energy efficient alternatives at the planning stage.
