Concrete has cracks from shrinkage that necessarily result from in hardening process. Shrinkage-reduced concrete developed for crack reduction was utilized at a sample construction project. As a result, it is confirmed that crack initation ratio was remarkably reduced when compared to the case of normal concrete utilization. Additional sample project is supposed to use delay joints as well as srinkage-reduced concrete. Subsequently, the result will be reported. The greatest factor which affects in drying shrinkage is unit quantity of water. However, there are a lot off difficulties in field supervision because proper measuring means is not presented in present standard. Therfore, problems depending on ready-mixed concrete concrete companies should be improved by preparing the related standard assoon as possible.

The Chicago Convention in 1944 made important contributions to aviation safety improvement, building an aviation safety monitoring system for its signatory countries. As ICAO is now on the verge of changing its supervision system from self-reporting to preventive Continuous Monitoring Approach(CMA) in 2013, we also expect our own safety system to make a progress accordingly. The government is pushing ahead with plans to build an integrated safety management system at government level that satisfies international standards and reflects domestic features. To this end, this report proposes the most effective system-building model, by analyzing the current status of the system that is in use and meets the requirements of international aviation agencies.

As recent construction projects are bigger and higher, the importance of lifting is increasing. In construction sites tower cranes are an essential lifting equipment covering were than 50% of all construction activities. But due to neglect of safety supervision, tower crane-related accidents are frequently taking place. Since most of construction activities is done in heights, the accidents are more likely to be catastrophic. According to an analysis of the causes of tower crane-related accidents, 49% of all accidents claimed for certain periods($1999{\sim}2003$) occurred in the process of telescoping work. Therefore, this research is conducted with the object of analyzing telescoping work of tower cranes and presenting solutions against safety risk. It is expected that the results of this study can be used as useful basic data or material when preparing for effective safety management for tower cranes.

In this study, the legal and institutional status of construction supervising and construction inspector was identified. As a result of examining the definitions of construction supervision terms, focusing on domestic construction-related laws, it was found that there were no consistency between each laws regarding 'terminology' and 'definitions'. In addition, the scope of construction inspector's work continues to expand through the delegation provisions to lower statutes, however, responsibility, authority, and inspection cost are not taken into account properly. In addition in order to introduce digital technology to the smart construction site, which is currently active under way, it is judged that the law and institutional contents need to be improved further.

There are the relevant provisions that apply to building regulations about the Building codes, Fire Protection laws, and more Multi-using interior finish materials businesses etc. The differences between these regulations are as follows: The Building codes is defined the main use of the building according to facilities to used to set the scale by the use of the floor space, On the other hand, Fire Protection laws are the basic purpose and the act of using the architectural space(or sales) by separating object by fire. And Multiple-using Businesses Facilities consist of two regulations engaged in the kind of law and the size of the floor area. One building can not be based on operating facilities and together in Multiple use businesses Law. As such, the Buildings are applied to the Building codes, Fire Protection laws, such as Multi-using Businesses Facilities interior construction industry due to the structural differences in the position of the designer feeling a lot of difficulties and confusion. The Multi-use businesses Facilities engage in the kind of law, the size of the floor area and seating capacity. These can not be based on operating facilities, and consists of two regulations together in one building. This study is purposed to help improving the finish of the interior architecture that is related to the Building code regulations, Fire Protection laws, Multi-using Facilities interior finishing material relevant with the provisions from the law through analyze the case of developed countries, and the current Multiple use Businesses Facilities research range from the law of multiple-using facilities, interior finishing, interior architecture for supervision reasonably and compensation for the interior design. So, Result is as follows: First, interior decorations can be separated the fixed material and the moveable things. second, It should be included multi-using Business though small size business space at the basement floor. third, It should be established statute law that design and construction responsibility. forth, re-testing fire resist performance after some period. and finally, it need to mitigate regulation where be installed sprinkler.

Investigation of the cause of the relatively recent building collapse accident in Gwangju revealed a lack of awareness about the safety of the dismantling construction system among stakeholders, in the form of issues such as illegal subcontracting, unauthorized design changes, and insufficient safety supervision. This study was conducted to analyze the safety interactions between the building dismantling construction system and the involved stakeholders and to propose ways to prevent accidents in related institutions and workplaces. AcciMap and STAMP-CAST analysis methods were used to evaluate safety interactions among the various stakeholders participating in building demolition work. Analysis results revealed that the collapse accident during the dismantling work was caused not only by structural causes occurring in the construction stage, but also by various causes throughout the system, such as the dismantling plan preparation stage and the construction permit stage. The results also revealed the need for proper implementation of safety control measures by various stakeholders to prevent collapse accidents during dismantling construction.

The building below standard scales to be built only by constructive report to authorities. Construction law 8 illustrates that supervision should be deployed in all the construction sites at the building which is found to have more than 3 floors and also to have more than loom of total squares in especially outside area of city plan zone. Such a small construction is have a important and the most basic meaning. Many problems were found to occur in all the constructive places which were out of the limit of this law. The construction sites were found to be controlled by public official's visiting without supervisors and designers of architecture. Technique of construction in architecture was found to be not different from that of 1980. The security of employees in construction on sites has a serious problem. Because of choosing ail the materials of the building without a reasonable point. All the building were found to have a law material about inside and outside aspects. The purpose of this study are to examine existing law about a small project and than to analyze the situation of constructive control through questionnaires and interviews with all the supervisors. Based on the data base of engineers who had a great experience in construction sites, The purpose of this study is also to suggest and advise the method of controlling all the items in architecture through on and off line.
