The aim of this study is to analyze the effect of the growing activities of large purchasing enterprises on the trust of small and medium size contractors, which is mediated by 'purchase accompany activity'. This subject study includes the first and second contractor companies in Korea. The results of this study are as follow. First, the knowledge and cost price sharing activities of major purchase vendor with cooperative company had a positive effect on the trust of cooperative company, however this was not so with the information sharing activities in that case. Second, the trust of contractors on large purchasing enterprises was positively influenced by sharing activities with purchasing activities of major company. Third, the knowledge and cost price sharing activities of purchasing enterprise with contractors on the sharing activities were mediated by the trust of contracting company on the large purchase enterprise. According to this study, the mediated effect of trust relationship can influence a contracting company. Whereas preceding studies of sharing activities were conducted about unidirectional instruct of large purchase enterprises to small and medium size contracting companies, this study was conducted on bidirectional effects, which included knowledge, cost price, information sharing activities between contracting companies and large purchasing enterprises. Conclusively, this study showed the possibility of spreading cognitive and change about mutual benefits strategy between small and medium size contracting company and large purchasing enterprise.

This paper is a study on FEED validation model that can be used in the bidding stage of small utility equipment in offshore plant industry using system engineering technique. Currently, domestic marine plant equipment industry companies are faced with the financial risk of project execution as they enter marine plant. The major cause was the insufficient ability to verify the FEED output from the contractor (Engineering or Procurement and Construction) of the equipment manufacturer (COMPANY or EPC). Therefore, we propose FEED design verification method that simplifies the system engineering method that sequentially applies requirements analysis, function, performance analysis and physical architecture building process. Also, we verified the suitability of the developed model by comparing the results of applying the developed FEED verification model and the verification method that depends on the existing experience for the small utility equipment (Air Compressor).

Under Korean law, small-to-medium-sized construction projects with budgets of more than 100 million won and less than 12 billion won must receive technical guidance by a visiting technician belonging to a specialized institution. This study proposed a method for calculating the technical guidance fee to prevent the potential inadequacy of technical guidance when the responsibility providing the technical guidance fee is changed from a contractor to a client. The method simplified the construction works which should receive technical guidance into four sections according to the construction amount. For each section, the number of instances of technical guidance per day provided by the visiting technician and the minimum technical grade of the visiting technician were limited, and the guideline for estimating engineering services fees was applied to calculate the fee per instance of technical guidance. The results show that the proposed method can be applied to the establishment of a technical guidance fee guideline since it well reflects the current fee distribution and K2B analysis results.

The contractor management is one of the important factors for the modem defense acquisition program. The occurrence of unlawful company causes the reason in which defense acquisition program is unable to be reasonably fulfilled and setback to the deployment of defense weapon system. In this paper, we propose the Artificial Neural Network to develop a prediction model for the discrimination of unlawful company in defense procurement. The data which are used in analysis, are obtained targeting domestic small & medium manufacture enterprises. It is expected that our model can be used to improve the program management capability for defense acquisition and contribute to the establishment of efficient procurement procedure through entry of the reliable domestic manufacturer.

The construction industry in developing countries like Vietnam, which incorporates small and medium construction enterprises, is typically more prone to disputes and contract dispute-related lawsuits. A dispute may occur at any time in the life cycle of the project. It is sometimes solved with the intermediation of a lawyer or directly by stakeholders. Understanding the causes of disputes in a construction project not only improves the efficiency of a company but also increases the success of projects. This study was carried out using a questionnaire survey at construction projects in Ho Chi Minh City. Sample data with 117 observations were analyzed to find the disputing factors in construction projects: diversity of working style among the parties; reluctance to work; and poor teamwork. Correlation coefficient on a rank of factors between design consultant and contractor; Design consultant and project owners are positively correlated. The Exploratory Factor Analysis (EFA) analysis identified six groups of factors in construction disputes: cooperation, technology, economics, productivity, information, and behavior. The findings are useful for enterprise practice and provide participants with an overview of sources of dispute. Thus, a more complete risk management plan can be formulated, which will accelerate project progress and improve the likelihood of success.

While the international construction industry for Korean companies have grown in market size exponentially in the recent years, the profit rate of small and medium sized construction companies (SMCCs) are incomparably lower than those of large construction companies. Furthermore, small and medium size companies, especially subcontractor, lacks the judgement of project involvement appropriateness, which leads to an unpredictable profit rate. Therefore, this research aims to create a profit rate prediction model for the international construction project focusing on SMCCs. First, the factors that influence the profit rate and the area of profit zone are defined by using a total of 8,637 projects since the year 1965. Seconds, an extensive literature review is conducted to derive 10 influencing factors. Multiple regression analysis and corresponding judgement technique are used to derive the weight of each factor. Third, cased based reasoning (CBR) methodology is applied to develop the model for profit rate analysis in the project participation review stage. Using 120 validation data set, the developed model showed 11% (14 data sets) of error rate for type 1 and type 2 error. In utilizing the result, project decision makers are able to make decision based on authentic results instead of intuitive based decisions. The model additionally give guidance to the Korean subcontractors when advancing into the international construction based on the model result that shows the profit distribution and checks in advance for the quality of the project to secure a sound profit in each project.

This study aims to discuss what changes Korean clothing companies and manufacturers have undergone with production facilities moving abroad due to offshore outsourcing and examine what conditions the clothing manufacturers are facing and how the clothing companies recognize those manufacturers. For these purposes, in-depth interviews were conducted with 24 firms with annual production capacity of more than 200,000 pieces among clothing brands for the domestic market, clothing exporters and promotion agencies. Those interviewed firms were the companies who were found to produce more than 200,000 pieces of clothing per year, and the interview-based survey was conducted from December 18, 2008 to January 30, 2009. The key findings from this study are as follows; first, a high percentage of interviewed firms were producing only a small number of items in Korea with a large part of their production line transferred abroad or outsourcing all of their production abroad only with their headquarters in Korea. Second, many were employing contractors rather than their own factories. Third, when asked about the wage levels of clothing manufacturers, many of the clothing companies gave responses such as: 'They are just our contractor, so we respect their decision,' 'We don't know because it's none of our business,' or 'We don't know at all.' Fourth, when asked about the work environment of clothing manufacturers, the clothing companies gave responses such as: 'We know in part,' 'To our knowledge, they conform to the Labor Standards Law,' or 'We don't know at all.' Fifth, the production line of clothing manufacturers featured straight-line systems, specialization, pairing and compounding/mixing. Sixth, it was found that clothing companies had interest in mass customization but their preparations were not satisfactory.
