Purpose: The purpose of the study was to contribute to the prevention of musculoskeletal disorders (MSDs) in 119 emergency medical technicians (EMTs) by evaluating ergonomic risk factors of patient lifting work-postures. Methods: Four procedures were evaluated: using long back-board (LBB) on the sitting and standing main stretcher, using variable stretcher on the sitting and standing main stretcher. Wok-postures were assessed during training. Results: In using LBB on the sitting main stretcher, the OWAS-score was Mode:3 (Mean:2.30, Maximum:3), the REBA-score was Mode:9 (Mean:7.61, Maximum:11), requiring improvement soon. In using LBB on the standing main stretcher, the OWAS-score was Mode:3 (Mean:2.33, Maximum:3), requiring as soon as possible corrective action, the REBA-score was Mode:6 (Mean:5.44, Maximum:11), requiring improvement. In using variable stretcher on the sitting main stretcher, the OWAS-score was Mode:1 (Mean:1.85, Maximum:3), not requiring corrective action, the REBA-score was Mode:6 (Mean:6.78, Maximum:11), requiring improvement. In using variable stretcher on the standing main stretcher, the OWAS-score was Mode:3 (Mean:2.84, Maximum:3), requiring as soon as possible corrective action, the REBA-score was Mode:11 (Mean:9.38, Maximum:11), requiring immediate improvement. Conclusion: All four-procedures showed improvement in work-posture. Thereby, required attention and management in training, occupational health professionals should participate in change of lifting-method, and programs aimed at preventing MSDs should be developed and implemented in fire-academy and fire-station.

The work-order performs an important role in make-to-order production. The development of work-order system in this production is more complex than work-order system in planing production. To construct work-order system, load of directors for work-order must be decreased, and production management between scheduling of master plan and current workshop conditions must be considered. In this study, we grasped troubles in present work-order system and flows of information for work order. Using these results are made database schemas and data flow diagrams for effective development of work-order system. And then, for successful establishment of work-order system and actual use of directors, we considered systematic and easy user-interface. For a case study, development procedures of work-order system are presented for plant factory.

The research aims to measure the control procedures' effectiveness, followed by the University of Northern Borders employees. A questionnaire was developed and distributed to the target sample of financial and auditing affairs employees at the university, where the researcher followed the existing descriptive-analytical approach. The researcher relied on the field survey, and statistical analysis (spss) was used. The researcher has found that the control procedures used are highly efficient in reducing public money waste. The researcher has presented recommendations that may contribute to developing the work of oversight in combating waste of public money. These recommendations include: Increase the interaction between the General Oversight Office and the internal oversight departments at the University of Northern Borders, the incentives provided to the oversight and accounting staff for their efforts to combat public money waste. It encourages them to maintain public money and work to obliging employees to undertake training courses periodically to develop their skills and rehabilitate them in line with modern control procedures. Also, more studies and scientific research on the waste of public money and types of administrative and financial Corruption and the law in all state sectors and reach conclusions and recommendations will help decision-makers amend laws and regulations to serve the public benefit of the university and the state.

Providing a "safe system of work" is the essence of the general duties that employers have to their employees under workplace health and safety regulations. Despite this, consistent and appropriate definition of what constitutes a safe system of work is almost non-existent. Available definitions tend to confuse a safe system of work with management practices intended to bring about a safe system, or conflate the broad system suggested in general duties clauses with procedures or work methods that are focused on particular hazards or tasks. This article develops a definition of safe systems of work which recognises the broad scope of the concept and includes psychological health and return to work processes. This definition can be used by a range of stakeholders to better communicate the scope of occupational health and safety duties and more consistently assess whether a safe system has been provided both before and after incidents occur.

To install heavy structures in the railway bridges, crane methods or launching methods using temporary structure have been applied. These methods are uneconomical because working yard is required, temporary cut of rail system, etc. In this study, various construction methods has been developed which are suitable to the filed conditions. In the case of simple span structure like plate girder bridges, the girder is loaded to troy system at the working yard and then transferred to the working place. To lift and lower the girder system, a new transfer system was developed. Different methods each for simple span bridge girder and long span girder were developed and detailed work procedures were proposed. Using these methods, the heavy structures can be installed with simple and safe work procedures and the construction cost and duration can be reduced.

ISO 9000 series, as quality management system that assesses quality system based on the documentation such as quality manual, documented procedures, specification is properly operated and then decides to give a certification, is a screening documented system that includes factors which may influence quality. Therefore, to have a proper documented system and its performance accordant to it is very important to the company which hopes to acquire the certification of ISO 9000 series. So, the objectives of this paper are to increase the efficiency of the work by cutting down efforts necessary to establish and revise documented procedures for the certification of the ISO 9000 series in the company using the documentation system.

The work presented here focuses on the development of suitable discretised formulations, for large-displacement shape and non-shape design sensitivity analysis (DSA), which enable the straightforward incorporation of structural optimisation into established finite element analysis (FEA) codes. For the generalised displacement-based functional the design sensitivity vector has been expressed in terms of displacement sensitivity. The Total Lagrangian formulation is utilised for modelling of large deformation of truss structures. The variational formulation of the sensitivity analysis procedure is discretised by using "pseudo" - finite elements, Results are presented for the sensitivity analysis and optimisation of standard truss structures. For the purposes of this work, the analysis and optimisation procedures outlined below are incorporated into the FEA code ABAQUS.

The rapid increase of electric power demand and the strong requirements for interuptiom-free made most distribution works being done by interruptiom-free work techniques. These trends lead to increase of accident by electric shock. It goes to prove that more than 80% of electric accident is due to the hot line works. Therefore, the countermeasures are very urgent. This paper suggests the improvement to prevent the work accident by interruption-free work through the examination of the present situation of interruption-free work techniques as well as analysing the problems in terms of live-line works and working procedures. These improvement will contribute to reduce the work accident in live-line work and enhance the construction quality by training and managing workers effectively.

Objectives: This study was done to compare patient satisfaction and hospital charges of surgery performed in an outpatient basis(ambulatory surgical procedures). Methods : This retrospective study was performed in 20(vitrectomy 11, tonsillectomy 9) randomly selected ambulatory surgical procedures patients and 50(vitrectomy 26, tonsillectomy 24) inpatients who. received the same procedure at a general hospital in Seoul since January 1, 1998 to October 31, 1998. The operative procedures were vitrectomy and tonsilletomy which could be performed on a ambulatory surgical procedures basis or on an inpatient basis. Results: The results of this study shows that the patients thought the expenses and the surgical operative time was an important factor in a ambulatory surgical procedures but there were no differences in the patient satisfaction by the method of surgery. The charges of vitrectomy and tonsilletomy were reduced up to 495,000 won and 380,000 won from l,589,000 won 842,000 won inpatient surgery respectively. Conclusions: This study focused only on the charges of the surgical procedures and did not include the cost of patient helper, the lost salary due to missing days of work to care for a member of the family, transportation costs, and other indirect costs. Therefore, if those fees were included, ambulatory surgical procedures would be more economical. Therefore, by giving incentives at the fee schedule, the government health policies it would reduce the total hospital charges.

There have been strong arguments that the best organizational type for the information society is a network organization which is intelligent and learning-oriented as well as has problem solving capacities rather than a traditional passive organization which strictly follows standard operating procedures. In this perspective, integrated information work environment emerges as attractive work environment for the 21st century. Integrated information work environment is defined as an integrated electronic environment that is available to and readily accessible be each employee and is structured to provide immediate, individualized on-line access to the full range of information, software, guidance, advice and assistance, data, images, tools, and assessment and monitoring systems to permit job performance with minimal support and intervention by others. Case study was performed to measure the productivity improvement by implementing integrated information work environment in life insurance company. The results show that there is a number of indications of strong work productivity improvements.
