According to 'The Analysis of Industrial Accidents in 2016' by Ministry of Employment and Labor, the number of deaths caused by accidents in the construction field is 391, accounting for 47% of 826 industrial fatalities in all industries. The breakdown of the 391 fatalities of the construction industry shows that 'struck by an object' accident had 30 fatalities, the 3rd in frequency following falling (235) and crashing (32) accidents. This study aims to explore ways to reduce the 'struck by an object' accident with emphasis on safety education and certificate system for rigging and slinging works. This study reviews literature on rigging and slinging works and analyzes 'struck by an object' accidents. The rules and regulation on the rigging and slinging works are also reviewed both for Korea and other countries with best practices in construction safety such as Singapore, Japan, U.K., and U.S. The rigging and slinging certificate systems of those countries are also reviewed to find any advantage in the construction safety management. In addition, a pilot rigging and slinging certificate system was executed in one of domestic construction site followed by two surveys: one on the riggers who participated in the pilot operation and the other on general managers in domestic construction sites. Based on the analysis of the 'struck by an object' accidents and pilot operation, this study proposes a rigging and slinging certificate system to reduce accidents, enhancing safety condition of construction sites. The certificate system was proposed in a way to accommodate working practice of construction sites. Depending on rigging careers and a crane load capacity, riggers are eligible to apply either basic or master certificate which makes difference in the level of rigging works. The safety condition of rigging and slinging work could be substantially enhanced if workers, managers, supervisors, administrators, and policy makers work together consistently.

Parking lot within housing site contains public interest of relieving parking space shortage problem and subject to public restriction. If auctioned off at higher price by excessive competition in general competitive bid for land bidders, the development of parking lot will be made against its original purpose supply. The core issue is that a bid price is quite often to be blown out of proportion by 150%~ 250% due to extreme competition and, could face serious problem if a winning bidder runs sale business. If it is rental business, although about 30% of the total floor space of the whole building to be used as neighborhood facilities, too high winning bid price cause to lose transparency. In case of sale at aggregate buildings, most business operators would sell 30% of the neighborhood facilities, spare the parking lot and manages thereof separately. According to Aggregate Buildings Act, neighborhood facilities are allowed for individual registration and ownership of parking lot by business operator or designated person by business operator. In this case, the parking lot becomes 70% of the total floor space of the whole building and 70% of the land share which makes the mortgage very valuable and easier for business operator to get financial loan. There used to be many cases such as owners of neighborhood facilities (aggregate buildings partial owners) who run parking lot to repay their loan running parking lot to repay loan, but found that very tough and reached auction and relatively disadvantaged. For parking lot within housing site, it is recommend to exclude the public factors that land has and take into account of public restriction in area (housing site). Business opportunity for operators and protection of property rights for buyers in aggregate buildings, land supply method is recommended to replace from highest bid method into draw or private contract. In terms of price, supply at estimated price (construction price) and restriction on usage (Co-ownership of parking lot) proposals are submitted.

The main purpose of this study is to assess the effect of using Balanced Scorecard, and relationship among learning and growth performance, internal business performance, customer performance, financial performance, and business performance. To achieve this study, theoretical and empirical studies related to Balanced Scorecard were carried out simultaneously. A field survey was undertaken through questionnaire sampling a population of construction firms. The established hypotheses related to Balanced Scorecard and organizational performance were verified by the paired-t test analysis using SPSS. The result of this research are as follows : First, BSC firm's learning and growth performance are higher than those of before BSC adopting firms significantly. Second, BSC firm's internal business performance level is higher than that of before BSC firm's significantly. Third, BSC firm's customer performance level is higher than that of before BSC firm's significantly. Fourth, BSC firm's financial performance level is higher than that of before BSC firm's significantly. Fifth, BSC firm's Business performance level is higher than that of before BSC firm's significantly. This study contributes to the BSC research by being the study focus on the BSC at the general indicators and provides evidence that may help understanding the possible relationship between BSC adoption and improvement of organizational performance. There are some limitations, however, of this study. The result are based on a cross sectional sample of construction firms, which may not be reflective of the entire population.

A construction supply chain needs an integrated information system, as the general contractor and subcontractors must communicate regularly with one another and share a substantial amount of information in their cooperative work. In the construction industry, supply chain management is necessary in the management of a system, including business process improvement, participant-oriented management, and the supply chain. This research proposed a supporting system and developed the prototype focusing on materials that play an important role in the supply chain. Construction projects are managed mainly through schedule management. As such, supply chain management should be linked with schedule management. The research implemented a prototype of the supporting system for construction supply chain management. The prototype was implemented in Microsoft Project using VBA, including a simulation tool based on @Risk for Project.

Korea Highway Corporation has played a role of the construction and operation of the highway for the past for 40 years. The private sector since the 90s has made highway construction and operation. Central government and local governments were paid at subsidy in least operating income to 1.5896 trillion won for private operators from 2001 to 2008. Thus, Korea Highway Corporation will have important implications for understanding the cost structure. Korea Highway Corporation, a general analysis of the input element is used efficiently. And the operation of labor and capital estimated highly of the substitution elasticities. Korea Highway Corporation are judged to need financial separation of a strategic outsourcing(business) enabled and the construction(maintenance and management) and business institutions. In addition, currently running at highway the operation of institutions combined to configure a new institution, if that institution invigorate the hi-pass, more of the country's highway believe to be increase operational efficiency.

In 2018, the real estate markets have hardly been transacted according to the government's tight regulations of real estates, and have the high possibility to reach a low hit due to the hike of loan interest rates following the U. S rise of base money rate. The key profits for the large construction companies mainly come from the overseas plant projects and the domestic non-governmental construction projects. They suffered a lot such as the lowering of their credit ratings due to the large losses caused by the frquent design changes and work delay. Even in the domestic non-governmental construction projects, the general business risks are on the rise due to the property marketing moving over to the decreasing phase. The small and medium sized security companies has realized a lot of operaring profits as they participated in the PF market to make up for the losses in the securities trading business. But, now as the housing market is not so good around the nation except Seoul and the financial states of large construction companies are not good enough, they can face the liquidity crisis if there happens the problems in the PF backed securities which they have handled. As Korean economy experienced the crisis in the savings banks before, it is recommended that Financial Supervisory Service proposes the preemptive control method and supervision direction to overcome the crisis.

A construction project is a designed product made up of labors, materials, and installations in the project positioned on the ground and may include the underground and ground section, and the section in water or on the water surface. It is a civil, industrial, transport, agricultural and rural development, infrastructure, or some other. A key phase in the life cycle of these construction projects is the implementation when building products are made directly with workers, equipment, materials, and managers. If there is a lack of management experience, information, and problem-solving solutions to tackle the risks faced by contractors, especially foreign ones, will fail in controlling the project's cost. This study was conducted with investigations, discussions, and evaluation of the factors that lead to cost overruns in the construction projects of international contractors in Vietnam. The principal component analysis (PCA) showed that those factors that influence cost overruns these construction projects fall into five general groups, including factors related to (i) the owners, (ii) the foreign contractors, (iii) the subcontractors and suppliers, (iv) state management, and (v) the project itself. Besides, the study proposes solutions to limit cost overruns in construction projects and improve the profitability of international contractors in Vietnam.

Public institutions guaranteed exclusive position of core business are likely to be inefficient in management. Past governments made various efforts to innovate public institutions. Participatory government drove innovation of public institutions through Ministry of Planning and Budget, and this innovation policy had problems as followings: shortage of common sense of innovation, lack of understanding of innovation, gradual execution of innovation instead of system innovation for business innovation, lack of consideration of characteristics of various public innovation, overlapping of evaluation system, and nonobjective design of evaluation indicator. MB government has diverse assignments for improvement of these problems as followings: transformation of business mind, voluntary participation of employee, improvement of management system of public institutions, reform of business evaluation system, promotion of internal competition, and construction of performance based business system. What is the most important point for successful reform of public institution is to achieve the support of general public with effective action plan and substantial programs.

The embodiment of working process fitting in characteristics of business each other in ERP system is indispensable factor. But, general ERP system is not so much profitable for the way of production management of footwear of domestic midge and small company that is dependant on most of the way of OEM production. Therefore, the development of ERP system fitted for present situation of the footwear manufacturing companies is necessary. For this, first, the business process for footwear production, for development of this system, have to be standardize and second, the model of Integrated system process based on standard business process have to be design for programming. In this paper, we proposed a method to build up standard business process and execute BPP in the point of the foundation for introduction and development of the resource planning systems only used by production of footwear and suited to the way of production management of the domestic companies manufacturing footwear. With this, we presented a process model of resource planning systems for footwear production. This study is focused on construction of integrated process model for production resource planning of ERP subsystems and the integrated process model consist of 13 modules.
