One-third of total energy and 50% of $CO_2$ emissions arise from construction phase. Because of this global amount of energy consumption and $CO_2$ emission, we must do our best to solve this problem. But our existing ways of meeting this problem has focused on the energy consumption saving of the construction and dwelling stage. On the other hand, we has been treated too lightly for handling the $CO_2$ emissions problem during the maintenance management and the demolition process so far,. In this paper, we quantitatively predicted and evaluated the environmental load in each construction step during all life cycle. And, we developed the environmental load assessment program for each construction step. And we proposed the reliable decision support model for objective and reliable environmental load assessment and reduction. This result must help the development of construction technology and low carbon & green growth.

This paper aims to clarify the game performance and its principle and operation method at the depth of successful content through gameness transition, which is one of the transmedia phenomena of games. This paper investigated the current state of gameness transition and analyzed the game structure and working principle by using Chris Crawford's creative expression taxonomy model. As a result, the types of gameness transition could be extracted into space exploration type, stage type, reasoning competition type, and mutual competition type.

Since the year of mid 2000, the EPC industry in Korea has the highest amount of orders received due to tremendous need form middle east asia region. However, the quality requirement from the owner is getting critical, which lead to the more competitive engineering capacity equipped. In order to do so, the development of objective and quantitative evaluation model of engineering process is essential. In order to develop the engineering checklist model for case-based evaluation of EPC project, first, the general description of worldwide EPC industry as well as the literature review of prior study have been performed. Then, the survey interview with experts in the engineering area of EPC project was performed In order to Identify the engineering work tasks and the critical check items, which should be checked during engineering process. Based on these checklist, the weights of check items as well as engineering work tasks also have been defined. The developed checklist model evaluated the two EPC project cases of S company in Thailand in order to explore its applicability. From the analysis of evaluation results, it is expected that the continuous implementation of evaluation based on checklist model can help the EPC practitioner check the critical items in engineering process more efficiently and take an appropriate action for better engineering performance, which finally can lead to the Korea EPC industry being more competitive.

Recently China's economy has been entered a new normal state with mid-speed growth. Along with the new normal state, Chinese government presented new development strategies. Among them, Beijing-Tianjin-Hebei Integration Strategy(BTH) has become the primary policy on the list of national economic development plan, and the BTH is expected to be the new model of regional development in China. With this background, this article firstly explains the concept and development process of the BTH, secondly presents the state of regional economies, lastly introduces some challenges ahead in the process of the BTH. The challenges, including industry structure adjustment problem, poverty belt in Hebei, environment problem and the distribution of functions of Beijing as a capital, are difficult to solve in a short period. It is needed more cooperative measures between central and local governments to cope with the challenges.

The mobile internet service market is growing very rapidly in Korea. This study outlines the current state of mobile internet services and analyzes the mobile contents types of media companies, especially newspapers, broadcasters and internet portal firms. As a result of this study, media companies provide generally different types of news and information for free and they are eager to develop the new mobile business models to maintain their power in new media. But mobile content distribution is still in the early stages due to the lack of clear business models. To satisfy the consumer's needs and to maintain the competitive advantages, the media companies should develop new business models and cooperate with other market participants to reduce the barriers in the mobile internet service market.

This paper describes and constructs object-oriented analysis models using Galois-lattices that we are always studying in discrete mathematics, shows fundamental approaches to maintain the models, analyzes the construction of object-oriented analysis models through good examples. Also, we define several properties of Galois-lattices that have binary relations between class objects, propose the incremental updating algorithms that can update the Galois-lattice whenever new classes are added. This proposal shows that in case of adding new class nodes the results from simulations can implement in constant time and have linearly the incremental structures in worst cases, and in that the growth rate of lattices is proportioned to class nodes in time complexity. This results can achieve the high understandability of object-oriented analysis models and the high traceability of maintenance models. Furthermore it is possible to make more efficient performances of class reusability in advantages of object-oriented systems and support truly the class hierarchical maintenances.

The hyper-geometric distribution software reliability growth model (HGDM) was recently developed and successfully applied to the problem of estimating the number of initial faults residual in a software at the beginning of the test-and-debug phase. Though the HGDM is a time-domain software reliability growth model(SRGM), it is not possible to compare the HGDM with other time-domain SRGMs. Furthermore the usual software reliability can not be computed. These drawbacks are derived from fact that the HGDM is not described in terms of the execution time. Thus we develop a continuous-time HGDM with binomial sensitivity factor in order to remove these drawbacks. Statistical characteristics of the suggested model are studied and its applicability is then examined by analyzing real test data sets. It is empirically shown that the continuous-time HGDM with binomial sensitivity factor can be used as an alternative to the current HGDM.

A dynamic compartment model was developed to evaluate the transport of accidently released radionuclides onto rice-fields. In the model, the surface water compartment and shoot-base absorption were introduced to account for the effect of irrigation, which is essential to a rice cultivation. The soil mixing by plough and irrigation before transplanting rice was also considered, and the rate of root-uptake and shoot-base absorption were modeled in terms of the function of biomass. In order to test the validation of the model, it was applied to the analysis of some simulated $^{137}Cs$ deposition experiments that were performed while cultivating rice in a greenhouse using soils sampled from rice-fields around Kori, Yonggwang and Ulchin nuclear power plants. The model prediction was generally agreed within about one order of magnitude with experimental data.

The global intelligent transport systems (ITS) market is experiencing rapid growth, and domestic ITS companies' efforts to extend its business abroad are steadily increasing. However, due to the burden of costs associated with the overseas expansion and the lack of strategy for local market, domestic companies' contracts for global businesses are far short of the technology. Although the government is actively promoting Korean enterprises' participation to overseas business, it has obvious limits due to the lack of its specialized strategy. This study established a customized export model for the countries in which Korean companies want to enter, and developed a strategy to advance into the local market.
