Recently, users who are interested in the service at indoor spaces is increasing. An indoor positioning system can minimize a range of positioning error using a variety of wireless communication infrastructure. Also, the system improves an indoor positioning accuracy by combining a mobile communication network. However, flexible positioning technologies regardless of an environment are insufficient. Therefore, this is time for a systematic study on an indoor positioning system business model. This paper classify differences between an indoor positioning system technology and outdoor positioning system technology. And we research a construction and application of the indoor positioning system that is adapted a wireless communication system (Wi-Fi, Bluetooth, RFID, UWE, Fingerprint, etc.) in domestic and foreign. We present a successful model of indoor positioning system and the development for future systems.

This paper uses super-efficiency DEA model and Malmquist index to evaluate the carbon emission efficiency (CEE) values of the nine western provinces along the "Silk Road Economic Belt" for the period from 2000 to 2015, and analyses the influencing factors of the CEE. The major findings of this study are the following: (1) the overall CEE of the nine western provinces is not high, and there are significant inter-provincial differences in the CEE. Meanwhile, the provinces with higher levels of economic development generally have higher CEE. (2) The annual total factor productivity (TFP) of the nine western provinces, which is mainly determined by technological change, is greater than 1. Moreover, the total average growth rate of the TFP is 15.5%. (3) The CEE of the nine western provinces is not spatially dependent. In addition, the urbanization, openness, use of energy-saving technologies and research and development (R&D) investment have a significant positive impact on the CEE values, while the industrial structure, foreign direct investment, fixed asset investment, government expenditure levels and energy structure have a significant negative impact on the CEE. Among them, R&D investment is the primary factor in promoting the development of CEE, and the government expenditure has the greatest negative impact on the CEE.

This study not only carried out to grasp about the sununarized characteristics of the relationship between international timber market and production trend of wood products, but also focused on the analysis of korean wood demand and the long-term forecast with econometric analysis. The result of regression analysis for wood demand in Korea is that coniferous roundwood demand(CIWD) is explained by coniferous foreign roundwood price(CWRI), Gross domestic product(GDP), a dummy variable. Non-coniferous roundwood demand(NCIWD)is explained by non-coniferous roundwood price(NCWRI), coniferous roundwood price(CWRI), a dummy variable. As the result of long-term forecast by base case, the total roundwood demand was forecasted $11,107,000m^3$ in the year 2000, $11,781,000m^3$ in 2005, $12,565,000m^3$ in 2010. As the result of scenario 1, total roundwood demand was forecasted $11,027,000m^3$ in 2000, $11,435,000m^3$ in 2005, $11,952,000m^3$ in 2010. And as the result by scenario 2, total roundwood demand was forecasted $11,341,000m^3$ in 2000, $12,208,000m^3$ in 2005 $13,257,000m^3$ in 2010.

In recent years, the objective information for the environmental effect of architecture will be furnished to the designer and inhabitant in order to minimize an excessive energy consumption and environmental loads by buildings. In addition, an environmental friendly architectural certification program for a residence, office, and school facilities have been operated to spread and supply environmental friendly architecture. Most of the environmental friendly architectural certification programs proposed in the country are focused on the aspect of the physical environments of architecture in its certification ranges. In the case of a foreign country, however, the certification ranges of an environmental friendly architectural certification program for the school facilities among the programs will be extended not only to the standards for architectural design, environmental aspect, and maintaining and management basis by considering the characteristics of educational effects for students but also to the curriculum, policy of environment, and roles of local community facilities by reflecting a social aspect. Therefore, this study proposes a design and evaluation method by considering an ecological element that will satisfy the requirement for educational well-being that includes not only the requirement for school facilities according to the development of a new curriculum like a space for teaching and learning but also the improvement of the quality of educational environments and the objective of an ecological school.

English immersion has emerged in Korea only recently as an innovative approach to learning and teaching English. Lack of real life experience of using English has been one of the biggest obstacles for Korean learners of English and has resulted in an increasing number of children being sent to English-speaking countries and a huge amount of dollar outflow. This recent innovation is expected to be the magic wand to resolve all these problems. However, setting up an immersion program in a typical EFL context like Korea has brought in another set of issues and challenges. The purpose of this paper is to examine the effects of a short-term immersion English program in Korea and provide some empirical data to develop programs that can better cater to the needs of EFL learners. A two-week English immersion program was developed and implemented with 57 Korean and Japanese students whose grade level ranged from 4 to 12. The study results show that the program was successful in terms of changing the participants' attitude toward learning English, improving their English skills, enhancing intercultural understanding and competence, and motivating them for further studies of English and other foreign languages and cultures.
