Delays are one of the biggest problems facing by the construction industry and they have significant financial and social impact in construction projects. The paper presents a framework of Delay Analysis System (DAS) with the aim of analysing the impact of delay factors in Libyan construction projects. The system has designed by integrating the possible delay factors, critical activities of a project using@risk simulator. A case study of building project was demonstrated to identify the impact of delays and the sensitivity of delay factor. The case study result showed that the project might be delayed by 97 to 103 days in comparison to the planned duration. The developed DAS is a tool for analysing and identify the impacts of delay factors and assist to construction manager to take necessary measure in reducing the delay impact. The paper provides a methodology for analysing the possible delay impact in a construction project and informing to construction manager in advance of the possible delay factors.

To improve the cost performance of construction sites, various systems and standards are constantly being developed and implemented. Although legal requirements for these system and standard improvements have been increasing, the cost efficiency performance of construction sites remains stagnant. We have digitized documents generated through construction supervision work at 39 building construction sites and proposed a model that can support decision-making in cost efficiency evaluation. This model selects key keywords that are considered to be highly related to cost efficiency by identifying the patterns and relationships of keywords through associated rule analysis and social network analysis using keywords derived from documents. In addition, it is expected to be used as a decision-making aid to determine the cost efficiency of a specific building construction site by establishing a logistic regression model using core keywords. As a systematic database of construction supervision documents and an integrated system of massive data generated by digital technology are established in the future, the accuracy and reliability of the cost efficiency evaluation model are expected to be reinforced.

In order to give back-to-farm residents the stable settlement environment in the rural area, the 'community village' is desirable as the village type and its village planning guideline should be supported as well. The purpose of this study was to develop a guideline for the planning of back-to-farm community village in the living and social environmental aspects, based on the comprehensive comparative analysis about items that field survey and literature suggested. The guideline for the living environment was developed for 6 items; village structure(adequate size, lot, outer space for household), village landscape(allocation, space composition), road system and transportation(parking lot in village, placement of bus stops, village trail, public transportation, road and pedestrian system), common living facilities and common space(number, size, location & placement, plan type, planning type of common facilities), transfer space, individual housing(type, size, planning type). The guideline for the social environment was developed for 3 items; village making and establishment(resident participation type, resident participation tool, residents' construction participation) and resident education in the course of planning, resident participation(gathering resident opinion, decision making, composition of construction committee, community newsletter).

The purpose of this study was to investigate housing DB construction for elderly people. Document research and content analysis methods were used in this study. The major results of this study are as follows. The number of elderly household is increasing very rapidly. In particular, they consist of a single person or a couple. These households prefer to live and age in a detached house. However, the social welfare system does not satisfy their needs. Therefore a systematic social support or welfare system is required to reflect their needs. For example, related works of housing welfare need to be prepared so that their data base system correctly reflects the socio-demographic characteristics and living conditions of the elderly.

With the recent increase of social demand of knowledge on traditional medicine, the construction of database is becoming a pressing matter. The reality is that while the social desire to adapt the high quality knowledge is growing fast, the field of Oriental Medicine has yet to organize its system. The number of Oriental Medical Doctors are limited, and there is no structured means of communication to expand the professional knowledge of these specialists to the public. Accordingly, an effective and structured knowledge system is in great need. In the process of building an Oriental Medicine database, prescription[方劑] and medicines[本草] are first in line. Consequently, we have taken the first step by organizing various methods to build the database containing information such as the formula, ingredients, composition, handling methods of herbal medicine written in traditional medical publications and herbal texts before the Song(宋) dynasty.

Even though the Korean intoner architecture market has constantly developed in the past on the basis of the economic and social growth, it has had a tough time for varied reasons since 1998. Restructuring in the construction industry is required due largely to both the lack of market demand which resulted from the foreign exchange crisis and managerial trouble which is getting worse as time goes by. In actual, as the social necessity for remodeling in skyrocketing, the remodeling is getting more acclaim. That is because old architecture generates a great amount of architectural trash, and it is necessary to look for ways to saute the energy. In the wake of these situations, the remodeling industry is drawing attention as an alternative to the marketable limitations of the existing construction industry. However, it is true that the remodeling market has yet to be activated decisively. Accordingly, the purpose of this paper is to provide a basis for entering into and activating the remodeling market of the interior architecture industry by analyzing the scale and recent conditions of the remodeling sector.

Social infrastructure facilities can be destroyed instantly when exposed to EMP (ElectroMagnetic Pulse), causing social chaos. However, concrete structures with low electrical conductivity cannot expect EMP shielding effect. Therefore, in this study, a metal sprayed thin film showing excellent EMP shielding performance was applied to a concrete structure to evaluate the metal spray welding efficiency and adhesion performance of the thin film according to the concrete surface treatment method. As a result according to the concrete surface treatment method, It was confirmed that the use of a roughening agent that generates physical irregularities in order to improve the welding efficiency and adhesion performance increases the physical performance of the concrete and metal sprayed thin film.
