In this research endeavor, we engaged with 70 construction safety specialists from established construction firms through surveys and interviews. The primary aim was to dissect and understand the weight and ramifications of specific cost items within the Occupational Safety and Health Management Funds(OSHMF) and Safety Management Expenses(SME). From our analysis, salient insights emerged. Within the realm of OSHMF, the cost items associated with safety facilities and the remunerations of safety managers were identified as paramount. It was observed that there are marked variations in the perceived significance and repercussions associated with diverse cost items of OSHMF. In stark contrast, when assessing the SME, the nuances in perceived weight and consequences of individual cost items were relatively muted, suggesting a more uniform viewpoint among the experts. Furthermore, our research probed the interrelationship between the significance and repercussions within OSHMF and SME domains. Notably, OSHMF manifested a positive linear relationship, suggesting that cost items of higher importance invariably had a more pronounced effect. On the other hand, the SME showcased a more subtle association, hinting at intricate underlying dynamics. The outcomes of this investigation are poised to offer instrumental guidance for enhancing safety protocols and diminishing accident occurrences in domestic construction undertakings.

The 5 working day's a week increase to fixed cost. Specially, the small & medium size company more increase to manufacturing cost. The introduction of 5 working day's rule influence to labor cost in manufacturing cost. Also, it make disappearance to fixed cost of 0.5 working day. Almost manufacturing company expect to have difficulty in product cost. The case of japan, many manufacturing company move to Asian countries after introduction of 5 working day's a week rule. The purpose of this study are the analysis of change product cost and suggest to solutions of productivity for a type of industries..

This study is intended to look into the effect of construction safety supervision system on risk control and reduction. To achieve this, a survey was carried out to 114 companies in construction, ordering, contract and management. The overall findings were as follows. The effect of construction safety supervision system on risk control and reduction showed that factors of supervision system, supervision cost and supervision method had a positive effect on risk control and reduction. And their perception of the introduction of safety supervision system in construction sites according to process showed that there was a difference between them according to the field of ordering, contract and supervision. There was the biggest difference between owner and contractor in double supervision system, but no difference between them in the perception of risk reduction. These results show that all ordering, contract and supervision are positively needed for the introduction of construction safety supervision. This means that there is a difference between owner and contractor in the perception of process according to system operation. All companies agree to system improvement by the settlement of safety supervision system for the prevention of safety accidents and safe construction, but the systematic complement of safety supervision is the burden of contractor. And there is a big difference between owner and contractor in the perception of responsibility and concern for cost burden.

Standard safety management cost system was established in 1988 as a decree Number of 88-13, first time. And then, it has been revised fourteen times, up to now. A lot of practical investigations have been made for the revision but many problems at sites are continued to be put out so that it should be revised. This study is to find out hazard level of each work kinds through questionnaire and interview and investigate analyze the status which standard safety management costs have been used. Also, this study is to show reasonable rates of standard safety management costs in construction industry and to set up countermeasures against those problem after reviewing its status in korea with in Japan and Europe. Budget and actually performed amount of safety management costs in this study are investigated. costs for temporary work which is clarified in Japan is collected in order to compare domestic cost rate with Japanese one related to the total project amount. This study is to investigate eleven project kinds of domestic system, first, and to investigate eleven items of apartment bldg, office, civil work such as bridge, tunnel, dam, plant etc, secondly.

IPS(Ideal Production System) is a strategic cost management establishing ideal target cost, innovating cost structure and reduction. However, IPS was commonly used in assembly industry acquiring components and using them to assemble vehicles etc. Applying IPS to steel industry is a new try and not easy because cost elements in flow manufacturing are clustered and obfuscated in a complicated way. This paper proposes ICM (Ideal Cost Management) method adaptive to steel industry. One of the biggest advantages is that ICM could classify and categorize costs in detail according to accounts and manufacturing machines. Based on ICM information, steps of extracting and maximizing ideas are followed effectively. From 2013, ICM was applied successfully to POSCO Pohang Steel Works 38 factories.
