Many construction companies have developed many kinds of information system to integrate the information created in the phase of planning, design, procurement, construction, and maintenance of construction project. However, the previous researches for the state of applying information technologies and the efforts of the analysis of the present information system launched in domestic construction industry is very rare. There also has been short of research on the construction decision-making support theory in construction business and industry. Hence this paper would contribute in identifying the state of information technologies and the theory of decision-making support of the information system in general construction company. and suggest the characteristic model on the information system for the construction decision-making support. The model consists of the two dimensions; (1) organizational hierarchy (2) data analyzing technology. This research, especially, can be expected to initiate the discussion on framework for understanding the construction decision-making support system in construction industry. The model is nut a practical methodology, but a window that offers a new perspective un sources of information system in each construction company, and thus can provide a clue of the useful guide to construction information system development.

Management process of apartment buildings construction has increased because the after service of construction company meet the needs of customers. Many defect data, which was inspected by construction company or customers before moving into a new apartment house, were classified by field engineers and then communicated to corresponding subcontractors. The classification process needs to be performed by an expert engineer because there is so much data, it is unfeasible to complete in a short period of time. For this classification process, an automatic classification system using case base reasoning (CBR) should be considered. This research proposed a defect management system with automatic classification system using CBR. This constructed defect management system consists of cyber after service system for tenants and the whole defect management process of construction, preservation and management of apartment buildings. This system could improve the efficiency of expert work in terms of time and accuracy, as well as helping laymen users to conduct defect classification work as experts do.

The purposes of this study was to investigate accuracy and indigenity of landscape plant species in planting design and construction at housing complex and offer basic data for improving precision of planting construction. The scientific name of landscape plant species was described in planting drawings at only two sites among twelve survey sites. According to analysis on indigenity of plant species in planting drawings, it was found that the component ratio of foreign species was the highest and the component ratio of native species at public housing complex was the lowest. The component ratio of landscape plant species in planting construction was severely differed to that of planting drawings. Also the component ratio of cultivar was higher than that of planting drawings due to planting of sevveral cultivars for one species in planting drawings. In the result of accuracy analysis on landscape plant species in planting construction, it was found that mean ratio of inacccurate species was 33.2% at public housing complex, 29.6% at local company housing complex and 26.4% at nationwide company housing complex. It was found that several cultivars were planted for one species in planting drawings. The representative species which were planted by several cultivars were Camellia japonica, Rododendron spp., Prunus spp. and Magnolia spp. and so on. In order to promote the precision and speciality of planting design and construction, scientific and cultivar name of plants should be described in planting drawings.

Many researchers in South Korea have conducted regarding the safety climate and concluded that the safety climate effect on the safety performance. However, the survey tools that were used in domestic research were developed by individuals or designed by reconstituting, translating from previous studies. In addition, the safety climate as a low factor of organizational culture showed up in different types depending on business scale. In order to solve this issue, the objective of this study is to analyze the safety climate level of construction company depending on business scale in South Korea. first, the survey is conducted by NOSACQ-50 for construction workers. Second, it is analyzed how organizational culture affected the safety climate. Finally, the improvements are suggested on the level of safety climate. In the future, this study will be used as a baseline for the effects of the safety climate on the safety performance in construction site based on business scale.

The purpose of this study is to examine the construction industry of Korea from the 1920s to the 1930s by analyzing activities of construction-contractors trying to overcome the recession of the construction industry and intensified competition in the industry. In this paper, I looked at the activities of Hanazono Sakichi as concrete examples. First of all, with the strategy of the vertical integration, by manufacturing and selling building materials, Hanazono Sakichi expanded his company and the scope of contract business. The second, he attempted to diversify related projects. Through related diversification, he seemed to have earned not only land management profit but also advantages from related construction. These aspects were not only seen by Hanazono's activities but also by other contractors'. On the other hand, a few contractors have taken over a trust company to secure the funds for land management. Attempts to maximize personal interests through the expansion and diversification of contractors' business can be seen as overcoming the pre-1920s environment, where almost construct works were ordered under the government, and creating opportunities for the private sector to work and make profit by themselves. In the end, it can be mentioned that 'the contractor' established 'the construction industry' through this process.

In South Korea, small photovoltaic equipment is increasingly adopted in more detached houses on the constant basis. With this broader use of small photovoltaic equipment, its systematic maintenance becomes all the more necessary. However, photovoltaic facility maintenance has been concentrated solely on large-scale solar energy generation plants in the country while hardly covering smaller facilities. In this research, the JEM rule and extant maintenance company services were analyzed to develop a proper maintenance model for small photovoltaic equipment. The maintenance service procedures designed herein are as follows: A small photovoltaic equipment user chooses a maintenance company and signs a contract. Once a contract is made, the Korea Energy Management Corporation provides a certain kind of incentive to the company. The company provides maintenance service to the user and receives a service fee. If such a maintenance service model is in place, small photovoltaic equipment efficiency is expected to increase and users could receive systematic maintenance services. Also the new creation of small photovoltaic equipment maintenance service would form a new market to generate more jobs for the society.

The measurement of business performance is important to secure the competitiveness of construction companies. Therefore, the purpose of this study is to analyze what is needed to increase the competitiveness of small & medium construction companies. In order to analyze efficiently, this study reconfirms the effectiveness of Key Performance Indicators(KPI) of construction companies selected from previous studies. The empirical analysis to find differences of KPI between small & medium construction companies and big construction companies is performed using the 4,286 construction company samples extracted by 'KIS-Value Data Base'. The results of the empirical analysis show that there are significant differences in characteristics of KPI between small & medium construction companies and big construction companies. Particularly, small & medium construction companies are relatively insufficient to invest for the purpose of preparation for future and long-term growth. Additionally, empirical tests reconfirm that most of the KPIs from previous survey studies are suitable as a performance indicators. The contribution of this study is to analyze empirically small & medium construction company's strong & weak points and the effectiveness of KPIs derived from previous studies.

Corporate governance is a system articulating the division of responsibilities among different company members, and defining the running rules and procedures for making decisions on corporate affairs. The separation of ownership and management in modern enterprises brings agency problems to the company shareholders, and it is wildly believed that good practice on corporate governance is essential to prevent managers from taking actions by which profiteering their own benefits but compromising the interests of shareholders. This research investigates the level of companies' compliance with the corporate governance codes to find whether significant differences in corporate governance practice exist between the listed construction companies and the national leading companies in Taiwan. Further exploration focuses on the correlation between the compliance level and the industrial features. The investigation finds that: (1)Construction companies display lower levels of corporate governance compliance; (2)Construction companies display lower levels of structural board independence and respect for stakeholders; (3)Compliance levels of construction companies are correlated with the number of employees and the ownership concentration; (4)Compliance levels of the whole sample companies are correlated with the factors representing firm size, such as turnover, capital and number of employees, but are independent of profitability as well as stock price volatility. The above empirical evidence characterizes the features of corporate governance in Taiwan listed construction companies, including: (1)Large companies lurking high risk of agency problems have more willingness to conduct corporate governance and meanwhile can afford higher costs for the conduction, so that their compliance level would be higher than smaller companies; (2)Construction companies in Taiwan have higher ownership concentration, on account of the industrial tradition of family business, and therefore pay less attention to the compliance with structural board independence and respect for stakeholders. However, the conclusions indicate that further studies are essential to clarify whether the above disparities would lead to a negative cycle of corporate governance practice in construction industry. The benefits of corporate governance should unfold more evidently to convince construction companies for improving their investment environment and stimulating their healthy growth.
