Let {X(t), $t{\in}\mathbb{R}^n$} be a $S{\alpha}S$ H-sssis Chentsov random field with control measure m. We consider a geometric construction for L$\acute{e}$vy-Chentsov random fields and Takenaka random fields. Finally, we proved some property of conjugate classes and a.s. H$\ddot{o}$lder unboundedness of $S{\alpha}S$ H-sssis Chentsov random fields for all order ${\gamma}$ > H.

$\lceil$The Construction Technology Development Master Plan$\rfloor$ aimed to promote construction technology R&D and to use its result efficiently is a legal plan based on Construction Technology and Management Law and established every five years. Now $\lceil$The 3th Construction Technology Development Master Plan(The 3th Master Plan)$\rfloor$ is establishing by MOCT(Ministry of Construction & Transportation) because the 2th Master Plan is completed at 2002. The 3th Master Plan suggests 'Establishment of construction environment leading the world-wide construction market' as a long-term vision, and also presents basic targets ; 'Improvement of competitiveness through conducting construction project efficiently', 'Transform into technology-oriented industry'. It consists of 7 fields and 25 main subjects. The 7 fields are construction manpower, production system, environment, safety, construction information, construction engineering, construction R&D.

In this study, we compared and analyzed the displacement of final excavation with measured value through an inverse analysis method used in urban excavation construction. We maximized the effectiveness of the inverse analysis method, and plan to achieve cost-effective and practical construction management in the field with identical conditions. As the first stage, we suggest an example of a field which has the inverse analysis method. We applied the inverse analysis method to three different fields on which construction and measuring were finished. Of these three fields, two fields showed a very satisfactory result. However, in one field, there were significant differences between the analysis and measured value. The result of our analysis indicated that, we should unite the conditions of the inverse analysis method and field construction. We need to thoughtfully reconsider the RANKINE earth pressure application in a triangle type. This is because the uniformity of earth pressure is made by its arching effect, in the condition of the displacement of lower underground occurring widely, which is differentiated with the earth pressure conditions of RANKINE, even if the slurry wall has stiffness. Also, when recalculating the soil parameter, we should emphasize the adhesion of the weathering zone, and give experimental consideration to ground water level.

Recently, remodeling has been introduced in the domestic construction industry as an alternative new construction. Its economic evaluation is the essential part of remodeling business. Therefore, this study has the purpose of presenting the method that is able to evaluate the actual value in the market. And this method can compare before & after value of remodeling in feasibility study. For this, this study reviews economic evaluation methods in construction and real estate fields and analysis their problem and merits & faults. With those facts, this study makes a mixed economic evaluation method that can be used in construction and real estate fields.

Construction industry try to use weather information because construction is much influenced by weather conditions. However, the researches, how to use the weather information in construction fields at present state, are not sufficient. Therefore, the purpose of this study is to present the methods for improving weather information application by analysis the present state in building construction fields. The results show that educations about application of weather information are poorly conducted though the construction engineers know that weather information is helpful to improve the performance and that weather information serviced is not suitable to apply their field's work. Based on the results, for improving the application of weather information, the construction engineers are structurally educated about applying weather information and the weather information system is developed to specialize the building construction projects. Additionally, construction companies have a long term plan to cultivate the experts who equally have a good knowledge and experience of weather information and construction technologies. These proposed methods help to decrease the influence of weather conditions and finally to improve the performance in building construction projects.

As the Scale of construction work is enlarged, complicated and diversified, construction information from the large number of construction sites is happened at site and reported to the head office. To simultaneously control the individual or large number of sites in large number of construction information, the necessity of making extract the important point of the information and the board of director's making a suitable decision to support the fields is increased. Also, as driving the construction industry to be informative, efficiently aggregating the information created in fields, efficiently making decision and controlling the construction work is increased the importance of the company's competitiveness factor. To simultaneously control multi-construction sites in the small and medium size construction firms define the fundamental and core information factor which needed in the head office and suggest the appling method.

Domestic construction industry has considerable level of construction performance and technology thanks to the economic development and as the result of performing diverse oversea construction project. However, construction disasters have been steadily increasing, and do severe disasters at faster pace. Most of such disasters happen at small and small medium-sized construction fields, which contract size is less than 10 billion won. small and medium-sized construction fields are not obliged to designate a safety manager, and have limitations in engaging self-regulating disaster prevention activities due to reduced budget for safety facilities. For the small and medium-sized construction sites with less than 10 billion won, the Ministry of Labor has been carrying out mobile inspections of construction safety. However, the effect so far is insignificant and an improvement plan is required. Therefore, in the present thesis, we derive problems appearing in the current construction safety mobile inspection system, investigate and study systems in foreign countries, and suggest an efficient and effective plan to operate safety technology inspections. First of all, we establish a standard to select sites to be inspected that are high in construction risk and disaster occurrence probability In addition, we suggest a plan to take administrative and judiciary measures based on the total score for disaster factors considering the disaster occurrence probability and the illegal practices. Furthermore, a scheme to maximize the effect of disaster prevention is sought by building an organic cooperative system between the Ministry of Labor, Korea Occupational Safety ＆ Health Agency and other organizations specialized in instruction of construction disaster prevention. Finally, we induce a research conclusion that leads to self-regulating safety management through checking and instructing systematic management on mobile inspections.

In this study, we firstly compute the energies and the angles of Frenet vector fields in Lorentz 5-space ��5. Then we obtain the bienergies and biangels of Frenet vector fields in ��5 by using the values of energies and angles. Finally, we present the relations among energies, angles, bienergies, and biangles with graphics.
