The trouble rank of business management of the small-medium manufacturing enterprises in Korea is constituted by that average 28.6% of production management in the worst trouble of business management from 1982 to 1999. The status of production management approaching problem is analyzed for Korean small-medium manufacturing enterprises and it us checked productivity improvement and requirement facts impede productivity improvement. It is expected to contribute much productivity improvement through a new established model of production management system and technique or tool for small-medium manufacturing enterprises in Korea.

The trouble of business management of the mining and manufacturing companies in Korea are constituted by that average 28.3% of production management in the worst trouble of business management from 1973 to 1980 So that Industrial productivity in Korea lower than an industrially advanced nation and then a change for the better of effective production management operations manufacturing companies are suggested by the application effects and achievement points of production management. Therefor Industrial Engineering technics is applied systematic route and the manufacturing company grow more than better its Business Physical condition for the improve productivity applied system approach for a rational product ion management system model.

Measuring performance of corporate information system has become one of the core issues in that development of the information system requires substantial amount of investments and the system works as a crucial leverage to enhance competitive edge. Most of the previous researches for performance of the information system have narrow and limited focus on such as the effect of user satisfaction and productivity. This paper suggests a model to measures the comprehensive performance which is classified as user scope (user involvement and satisfaction), operational scope (task productivity, task innovation, customer satisfaction, management control) and efficiency scope (financial performance), and to represent the relationship among the scopes by the path analysis model. Followings are conclusions from statistical hypothesis test of the model: (i) user involvement through user satisfaction has positive effect on all the performances in the operational scope, (ii) task innovation and customer satisfaction in the operational scope has statistically significant impact on financial performance but task productivity and management control do not. This conclusion indicates that task productivity and management control has the long term effect in nature, and evaluation of the information system has managerial implication when it Is measured in comprehensive performance which includes internal operational performances as well as financial performance.

The purpose of this study is to reform the productive industrial relations in hospital. Because the industrial relations of hospital is antagonistic each other and this problem cause a low productivity. In Korea, hospitals maintain their ownership structure, strategy is controlled by government, short process of management, and culture of grade. The executive of hospital doesn't gain the confidence of union. This circumstances is related with the antagonistic industrial relations. This research is to analyze hospital management system through experiential and literature study, and is to present a reform strategies for cooperative industrial relations of improving productivity in hospital. As a results, if the hospital manager hopes to improve productivity, they should introduce expert management system rather than ownership and management system. And it is need to execute the hospital initiative strategy rather than to depend on the government. Moreover, the hospital can achieve productive industrial relations as a middle-long term visions in management process and horizontal organization culture. Although this study is limited by literature research, it will contribute to settle productive industrial relations in hospital and to accomplish the additional study.

Based upon previous research, factors affecting office productivity with the Accounting Information Systems(AIS) were suggested, and the relationships between the factors and the office productivity with the AIS were hypothesized. The empirical results suggested that there are significant positive relationships between the factors such as the user participation, level of AIS utilization, internal AIS development and AIS technical sophistication and the office productivity with the AIS. According to the results, the office productivity increasing strategy with the AIS were proposed.

Over the past 40 years, Korea's defense industry has been deepening into a low-efficiency industrial structure as the government directly controls prices, quantities, and costs. By implementing the Defense Industry Building Act in 2021, the government is creating a healthy ecosystem for the defense industry and strengthening its global competitiveness. In this study, based on KPC's Productivity Management System (PMS), a diagnostic model of defense companies implemented since 2013, the on-site diagnosis was performed from 4 to 28 days depending on the size of the company data was collected based on the results. The causal relationship was analyzed through structural equation model path analysis for the effect of innovation capability on productivity performance. As a result, it suggests that defense materials suppliers should focus on which core processes to innovate and strengthen and improve their innovation capabilities.

This paper deals with the productivity increment through construction of lean production system for automobile factory in China. This lean production system has been progressed according to 5 steps. Step 1 is the work preparation. Step 2 is the process design. Step 3 is the establishment of method to count production quantity. Step 4 is the establishment of measuring method for input and output. Finally, step 5 is the construction of flexible production system able to adapt for environment change. This lean production system is expected to obtain the productivity increment by 50% for plastic plant and reduction by 50% in inventory quantity.

The ongoing debate over IT productivity has revealed paradoxical effects of IT. This study proposes that IT business value is paradoxical structured. IT impacts are not easy to generalize according to one perspective or paradigm. This study assumes multiplicity in the phenomenon of IT value and explores effects of these multiple interpretations. The study seeks to understand organizational performance. Hypotheses are developed to test the relationship between competing interpretations of IT value and organizational performance. The purpose of this study is to determine whether or not senior managers perceive IT value on the basis of divergent managerial value frames.

Safety of workers and productivity in construction site are affected according to the conflict status of work spaces which are performed at a time. The interference among the work spaces in construction site should be minimized because it becomes a blocking factor that causes construction delay and low productivity. Those factors can be managed by reasonable H&S (Health & Safety) practice. This research suggests the requirements of H&S practice and rules to establish the strategy of H&S management based on the literature reviews related to H&S rule. The suggested H&S rule can be visualized for searching space conflict point if the rule is linked with visual simulation tool. Accordingly the research results can be used for improving and visualizing construction productivity by work space control in 4D/nD CAD system.

Construction managers who are placed on the top of the construction production organization should exhibit its best knowledges concerning all aspects and control related members at every position properly. In case of CM firms in developed countries, they are equipped with a practical system of technology and management knowledge, and efficiently use the knowledge not only for novices but also experts. However, the domestic CM firms which are now at the lower level than those in developed country are not supported with the sufficient and systematic knowledge for CM tasks due to various reasons. Therefore, the objective of this study is to suggest the direction and strategy for the development of an experts-knowledge management system to enhance the construction productivity at the viewpoint of CM firms which conduct, manage and supervise various tasks of construction projects. Domestic CM firms would play a great role to enhance productivity and secure competitive advantage of project management as much as the firms in developed countries if experts-knowledge and information are supported by a computerized system.
