As the life cycle of buildings is expected to increase, new constructions will decrease and the proportion of remodeling and repair will increase. Therefore, there is an increasing need for overall performance management of old buildings. In 2020, the proportion of buildings over 30 years old is expected to reach a half. As a result, the demand for securing and improving the performance in the stage of using the building is increasing due to the change in the demand for the building, such as the decrease in the construction permit and the increase in the use of the existing building. From this perspective, the study sought to consider institutional measures to organize the preventive and conservative maintenance of buildings. For this purpose, the conceptual goals of inspection for building maintenance were set through a literature review, and the status and problems associated with building maintenance were analyzed to suggest ways to improve the inspection system for building maintenance.

Korean society is changing into multicultural society with increasing international marriage and immigrant influx. The increasing number of immigrants in Korean society suggests the necessity of social and economic integration of people with diverse cultural backgrounds. We study the entrepreneurial intention of multicultural immigrant. Cultural intelligence is closely related with sustainable value and belief to their eagerness in surviving of the 2nd country. Cultural intelligence is the individual's capability to function or manage effectively in different cultural settings or in multicultural settings. It is assumed that the cultural intelligence of multicultural immigrant might affect the entrepreneurial intention. Based on the theory of planned behavior, we set up the research model. 243 usable responses of multicultural immigrants in Korea were analyzed. Our findings suggest that cultural intelligence positively affected entrepreneurial intention by affecting subjective norm and perceived behavior control. This study contributed the study of the entrepreneurial intention and multicultural immigrant.

This paper analyzes the variation law of the pipe lateral vibration characteristics, it was treated as a beam model, and was dispersed into several subunits based on the FEM. The corresponding stiffness and mass matrix of the pipe was deduced by using Hermite interpolation function, and the overall dynamic balance equation was established. The lateral vibration under different pipe lengths, thicknesses and towing speeds are solved by integral method. The results show that the pipe vibration trend decreases first and then increases, and the vibration value at the ore bin is larger than that at the pump set, and the value at the top is the largest, and the least value location can change with the length increase. Increasing length and thickness can reduce lateral vibration value, while increasing speed can increase the value. Neither the thickness nor the towing speed will change the location where the least value occurs. The vibration intensity will increase with the decrease of pipe length and thickness and the increase of towing speed.

The article deals with increasing the effectiveness of educational content on the YouTube channel with the help of built-in analytics tools. Particular attention is paid to the creation of quality video, taking into account the reaction of end users of video materials. Ways to increase the video audience are considered. Techniques for improving video content apply to individual videos, as well as playlists and channels in general. In this case YouTube is both an independent educational platform and an auxiliary platform in a set of various educational solutions.

Corporate social responsibility (CSR) is of increasing interest to both industry practitioners and academics because of increasing public awareness of environmental, economic and social sustainability. The last decade witnessed a large number of studies on the development of CSR principles and the implementation of CSR in various industries such as the mining industry, oil industry and food industry. However, there is limited number of CSR studies focusing on the construction industry. Considering the critical role the construction industry plays in achieving economic, social and environmental sustainability, it is imperative to extend the current CSR research to the construction sector. This paper provides a critical review of literature related to corporate social responsibility in construction context. A special focus is placed on the current practice adopted by the industry to be socially responsible. A research agenda is set up to tackle this critical issue.

UV-curable resins have adventages of quick set, space saving, clean environment, and efficient use of energy. The polymerization induced phase separation has been studied to solve the problem in UV-curing of thick films and develop the new functional materials. On the exposure to UV irradiation, the dynamic elasticity properties were mesured for mixtures of alkyd resin and UV-cruable monomers which have different molecular structures and molecular weights. The curing rate increases with increasing temperature and UV intensity. In addition, The gel point is strongly influenced by temperature and UV intensity

Traditionally, classification of remote sensed image data is one of the important works for image data analysis procedure. So, many researchers have been devoted their endeavor to increasing accuracy of analysis, also, many classification algorithms have been proposed. In this paper, we propose new bands selection method for multispectral bands of remote sensed image data that use rough set theory. Using indiscernibility relations in rough sets, we show that can select the efficient bands of multispectral image data, automatically.

The increasing utilization of radioactive isotopes in industry, medicine and research has raised the question, 'How should hospitals deal with radiation injuries when they occur?' A system for initial management of radiation injuries has been developed by Radiation Management Corporation. Radiation injuries are classified and a treatment plan outlined for each at the emergency and short term medical care phase. This system includes clinical prognosis as well as a detailed plan for quick set up or a Radiation Emergency Area in any hospital. Procedures for patient admission, preparation of the facility, general decontamination, sample taking, and wound decontamination are included.

We study the optimal allocation of machines and pallets in a class of manufacturing systems. The FMS is modeled as a closed queueing network with balanced loading of the stations. An Algorithm is developed, which exploits the properties of the throughput function and solves the allocation problem for increasing concave profit and convex cost. We also study the more general case of allocating machines and pallets among a set of FMSs. A dynamic programming approach is developed, which solves the problem with O(M$^{3}$N$^{2}$) operations.

Authentication between Server and Client is necessary in most of Internet Service because of increasing of using of Internet. Unix-based Server upgraded security of user authentication using "Shadow Password" instead of "crypt" function. But "Shadow Password" most use same authentication method about all services. But we individually can set user authentication method using PAM(Pluggable Authentication Module). This paper will propose user authentication system using Linux-PAM that use SMART CARD as authentication token.
