  • There is commonly used the full depth excavation method of sewer pipeline maintenance in Korea. This induces couple of technical and social problems like increase of construction cost and time for excavation and backfill, increase of public complains and delay of traffic, and so force. In order to overcome these problems, lots of laboratory tests were carried out for sewer pipeline of maintenance materials with trenchless methods. The testing materials are liquid and hardened polyurethane, and polyurethane CIPP. The lab tests were followed by Korean Standard. There are no side effects, like harmless to the human body and air pollution with stink. Judging from the limited test results, all the items tested were satisfied the KS criteria.

Second, the whole is made up of color that is applied to mist gray/low chroma in the value and chroma stakes. Especially, high chroma is extracted by only commercial old house, the rest is made up of middle and low chroma color. Third, dark color is the most by KS Color System and dark reddish gray and medium gray are occupied most part. Fourth, the whole atmosphere of village is static and hard, and the image is researched as gentle. Through the research, It applies extracted color palette for plan and preservation of traditional folk village. As using the color that is reflected in national and local distinct characteristic, preserving the color reflected in history and culture of the village, and applying color planning considered harmony with surrounding environment, it is expected that it can help to direct the color involved traditional and cultural meaning.

  • The installation of lightning protection system has recently been increasing, but the amount of damage has still been increasing. In this study, survey (interview) and field conditions were conducted to identify the installation and safety standards of the lightning protection system. it was analyzed that the safety management system is non-existent at the stage of the design, manufacturing and construction of the site lightning protection system, and that the safety inspection of the lightning protection facility is not properly managed. It has been shown that lightning protection systems, that can solve these problems, need to be re-established according to the reality so that safety inspection can be carried out in accordance with safety standards such as management of safety certification products, operation of survey institutions, design, manufacturing, and construction of safety standards at a national level.

  • The purpose of this paper is to investigate the three aspects of the construction and common use of old document DB in the foreign countries: i) the processing of old documents, ii) the problem and improvement of DB systems of old documents. and iii) the common use of old document DB. Results from this research are as follows: The National Library of Korea(NLK) copied old documents in the foreign countries from 1982 to 2006 and published the brief catalog. The Reogang Publishing company issued four volumes catalogs of old document in Japan. The National Research Institute of Cultural Heritage(NRICH) investigated old books and published some catalogs of several organizations in Japan. America. France. and all. The National Institute of Korean History(NIKH) investigated old archives and published some catalogs of several organizations in Japan. The characteristics of the Korean Old and Rare Collection Information System(KORCIS) of the NLK, the Old Books Cultural Heritage in Overseas System of the NRICH. and the Korea History DB System and MF Catalog/ Image System of NIKH were described in the DB systems of old documents, the problems of DB systems were checked over and some alternatives were suggested. In the common use of old document DB, KORMARC format and description rules(draft) for archives should be revised to adopt a new standard such as KS editions. and all the institutes involved should thoroughly follow the standards. when creating bibliographic records and digitizing texts. It is necessary to educate and train the specialists of old documents. A government organization should be established to supervise all the procedures of developing technology for sharing digitized resources. using contents. and cooperating with the related internationl organizations and institutes.
