Construction management system has been needed to be anchored and revitalize in these days, since it was entered into a domestic market. We could consider application of CM services as a challenge of construction project system and a way to get to an advanced nation in construction field. Application of CM services could be possible in public projects by a regime. However, in case of private construction projects, it is hard to apply it without understanding of substantial necessity and propriety. so in this study, we find a application method of CM services to private small-midium construction projects, and make CM services item table of CM services for revitalization by examining the cases that applied to in private small-medium construction projects.

This paper describes the development and implementation of a algorithm to decompose word images from image regions mixed text/graphics in document images using statistical analyses. To decompose word images from image regions, the character components need to be separated from graphic components. For this process, we propose a method to separate them with an analysis of box-plot using a statistics of structural components. An accuracy of this method is not sensitive to the changes of images because the criterion of separation is defined by the statistics of components. And then the character regions are determined by analyzing a local crowdedness of the separated character components. finally, we devide the character regions into text lines and word images using projection profile analysis, gap clustering, special symbol detection, etc. The proposed system could reduce the influence resulted from the changes of images because it uses the criterion based on the statistics of image regions. Also, we made an experiment with the proposed method in document image processing system for keyword spotting and showed the necessity of studying for the proposed method.

Operation of intelligent transport systems technologies in transportation networks and more detailed analysis give rise to necessity of dynamic traffic analysis model. Existing static models describe network state in average. on the contrary, dynamic traffic analysis model can describe the time-dependent network state. In this study, a dynamic traffic model for the expressway system using FTMS data is developed. Time-dependent origin-destination trip tables for nationwide expressway network are constructed using TCS data. Computation complexity is critical issue in modeling nationwide network for dynamic simulation. A subarea analysis model is developed which converts the nationwide O-D trip tables into subarea O-D trip tables. The applicability of the proposed model is tested under various scenario. This study can be viewed as a starting point of developing deployable dynamic traffic analysis model. The proposed model needs to be expanded to include arterial as well without critical computation burden.

The reductions in final waste form and material costs, which were induced from an introduction of salt waste regeneration system, have been estimated and compared with those of the present pyrochemical process, which is under development in KAERI. The results calculated on the basis of published data and proper assumption showed that the final waste form of LiCl waste from the Advanced Conditioning Process would be reduced about 3.7 to#ton HM (from 5.4 to 1.7 ton/ton HM). For the case of LiCl-KCl eutectic salt waste from the electro-refining process, the final waste form would be reduced 2.3 ton/ton U. Thus, these estimation suggested that the introduction of salt waste regeneration system was essential to improve the economical efficiency of the pyrochemical process.

The Change of environment related to human life, science, technology, economics and education level have much effect on home life. Therefore Home Economics Education have to get out of past trite concept that it is only a method to become good housewife and take the role to widen the human life and to grow creative power as a academic part of science. For these, Home Economics should become life education, life education of secondary school has to have relation to lifelong education. To achieve effective result from Home Economics Education, the object, system and methods of Home Economics Education, the object, system and methods of Home Economics Education have to be improved and teaching material has to be studied systematically. As an object of aboves and education planning in clothing is made for deep understanding the study of Home Economics Teaching Material. And to understand the real state, made some questions, had interview with 63-teaching in Kangweon province and show the results. 1) Tab 1~20 are the level of recognition about object, teaching content, time structure of secondary school. The object is recognized as cultural education and basic job education. 2) Tab 21~30 show the real state of textbook and study of it. To take effect from school lecture other teaching material except textbook is required. 3) Tab 31~40 are the result of sewing and handicraft practice. Sewing and handicraft needs much time and almost all time is used in practicing. 4) Tab 42~54 are the planning of textbook study for effective teaching, self-estimation and teaching material making is also considered. All above is collarless blouse’s planning. Base on above result, all objects of clothing life should be teached. For the development of Home Economics Education 1) Understanding and affection of teachers is required. 2) To solve indicated problem, national policy, education plan in school and education finance are fully supported. 3) More studies is required in Home Economics Education.

Scientific/technical data whose reliability is authorized have to include physical/chemical constants, authorized property value or authorized scientific statistical values so that the scientists in the same field use them continuously and repeatedly for their research. The data also have to be managed as Standard Reference Data that will be used in other area nationwide by analyzing, evaluating and authorizing the accuracy and reliability of the information with scientific methods. This study suggests a plan for establishing the National Center for Standard Reference Data as well as a necessity for managing the data produced in research process as a national Standard Reference Data. Also, a prototype of research information system for measurement standards is developed and described in detail for research information for measurement standard to be used as a reference data, then a plan to managing national reference data is suggested, in addition.

This study is to investigate the problems of procurement circumstance of the current fire service funds and to suggest the alternatives for procuring the fire service funds for dealing with increasing demand on the fire service in the local autonomous era. The results are as the followings. First, most fire service officers see the procurement circumstances as premature stage and perceive the necessity of the improvement of this condition. In particular, the officers at the fire center recognize this problem as an urgent question than the officers at the front fire branches. In addition, as for the alternatives of the procurement of fire service funds, both groups prefer the long term plan to the short term plan, and show positive responses to the National Emergency Management Agency and central government as the entity to raise fire funds. As for the alternatives to improve financial system, both groups show the most positive responses on the way to increase the current common facilities tax. As for the specific procurement alternatives of fire funds, both groups agree the alternative to increase common facilities tax mostly, and to the next they agree the alternative to insecure fire funds by restructuring current financial system and by establishing fire service hospital and fire equipment maintenance center.

The government set up a comprehensive plan for EC vitalizations in February 2000 and has begun implementing it. They hope to introduce EC into the economy at large and invoke reconsideration of its efficiency and transparency in the public sector. To accomplish this, the government has built EC utilization system within the industry and trade. However, the overall EC in the construction industry is below expectation. With the aid of the government, larger construction companies are building E-marketplace by increasing the investment in IT and organizing a consortium. On the other hand, small and medium construction companies have difficulties in investing in EC. On the basis of a field research, this study investigates problems that small and medium construction industry confronts in a domestic environment and EC system. It also analyzes the limitations of the tax reduction law for EC. Therefore, this study suggests a counterplan that defines the importance of a government guided plan and necessity of providing incentives to encourage EC Utilization degree.

The necessity for a technique to protect intellectual property of a digital content has been increasing, especially for the image/video contents which are the most favorite because of their high information-intensive property. According to this demand, this paper proposed a digital watermarking algorithm, which is recognized as the most promising technique. This algorithm targets MPEG compression system and the watermarking process is to be performed during the compression process. It inserts watermark only in Y components of I-frames. Experimental results showed that the proposed method satisfied both imperceptibility and robustness against various attacks. The PSNR difference between the compressed images(the average compression ratio was about 27:1 with Y:Cb:Cr=4:2:0 color format for TM5-based compression) with and without watermarking was only 1.8dB ($4.2\%$). In each case that the resulting image after an attack was reusable the normalized correlation between the extracted watermark and the original one was above 0.8.
