  • Background: This study investigates improvements in non-value-added nursing activities in clinical work, in order to improve the efficiency and quality of nursing activities. Methods: The study was performed as a quality improvement project at a tertiary general hospital. The nursing activities that needed improvements were categories into admission care, discharge care, supply management, diagnostic work-up related activities, and others. The nursing time and frequency of non-value-added activities were compared across nine nursing units before and after implementation of the quality improvement program. Post-implementation patient and nurse satisfaction were subsequently analyzed. Result: Post-implementation, the time spent on non-value-added nursing activities was reduced and patients and nurses were satisfied with the improvements. Discussion: Reducing non-value-added activities in nursing can increase the work efficiency and ensure time for patient care, thus improving the quality of nursing care. For further study, accurate surveys on nursing activities based on nursing time are required.

  • Conventionally, the snap reading technique was applied to the survey of ends-break in ring spinning and the supervisors have made the use of analytical data that were estimated by the Poisson's probability law. This procedure requires considerable time lag from the beginning of the survey to the decision of criterion. It will be beneficial if ends-break in ring spinning are surveyed by the population inspection method within the real time domain instead of snap reading technique. The authors developed the population inspection technique by the use of simply designed sensors for the ends-break in ring spinning frame and the analogue quantity were converted to the digital data to construct the net work for the data logging and computer software of criterion of operation efficiency within the real time domain. In this paper the authors will present the whole aspects of the sensor and data logging net work as well as the software for the machine efficiency, work load of ring frame operator and the others needed to the management of ring spinning process.

  • To help the corporations ensure more efficient production management, the Enterprise Resource Planning (ERP) system has been introduced in operation, together with a variety of approaches to make improvements in terms of quality and productivity issues. Yet, with the different types of ERP systems in operation, many companies are going through many difficulties not only in having greatly reduced work efficiency but also in making prompt decisions from the entire group-based integrated information. In this study, the analysis was made on their own ERP systems and working processes operated by a company running the multiple number of productions from the domestic and the overseas suppliers, in order to support their interacted work flow regarding their products and help improve the work efficiency by establishing standardized ERP system. Through this, it is expected to ensure more competitive system in operation by securing the flexibility in the production as well as efficient resource distribution under the corporate context of cost reduction and quality improvement.

  • A large volume of work has been attempted to improve the separation efficiency of cyclone by establishing new design and optimum operation. An auxiliary device called Post Cyclone (PoC) has been introduced and tested in an earlier work (In order to reduce the emission of fine dust from the reverse flow cyclones). This work applies the PoC to remove the dust and gaseous elements using a centrifugal effect remained in the discharging flow over the cyclone. As a result of the experiment, the efficiency was found best at the high gas concentration and low inlet velocity.

  • PURPOSES: Regional offices of the Ministry of Land, Transport and Maritime Affairs use a computerized system called KAMIS so as to manage road equipment systematically. Road agencies can record number of operating days by equipment, actual working hours, accumulated operating hours (or distance) by equipment, and operating cost. However, KAMIS does not provide critical information, although it is strongly related to efficient road management equipment operation. In other words, road agencies do not know whether they have sufficient equipment to handle their actual work. METHODS: Therefore, this study suggests a methodology to evaluate for operational efficiency of road management equipment using analytical hierarchy process(AHP). First of all, estimated weights related criteria can be produced by AHP, and then use operational history by pieces of equipment. RESULTS: Results show that importance of management work can differ from weather conditions through five areas. CONCLUSIONS: Commonly, this results can imply to help save money for the purchase and maintenance of road management equipment, and they would improve the functional performance of KAMIS.

  • This paper describes a method for tracking attitude and position of underwater robots. Underwater work with underwater robots is subject to differences in work efficiency depending on the skill of the operator and the utilization of additional sensors. Therefore, this study developed an underwater robot that can operate autonomously and maintain a certain attitude when working underwater to reduce difference of work efficiency. The developed underwater robot uses 8 thrusters to control 6 degrees of freedom motion, IMU (Inertial Measurement Unit), DVL (Doppler Velocity Log) and PS (Pressure Sensor) to measure attitude and position. In addition, the thruster allocation algorithm was designed to follow the control desired value using 8 thrusters, and the motion control experiments were performed in the engineering water basin using the thruster allocation method.

  • Through smart work using by smart technologies, many organizations wish to change traditional working styles. Lots of organizations, however, wish to do work with smartness through adoption of smart work technologies, those are not sure whether smart work will be successful or not till now. Viewpoints of members concerning efficiency and effectiveness from smart work who operate the organizations may be different. Therefore, hopefully, this research tried to investigate whether differences among members of organizations by empirical and exploratory approach. Totally, 118 questionnaires had been collected and performed test of mean difference between groups. As a result, some items such as working place, working methods, flexible time and tension of smartwork showed significant differences among groups and non-leader and leader groups. And, furthermore, from this research I believe that we can have a few insights for successful smart working environment in organizations. For successful smart work, organizations have to try to overcome or minimize differences among members of organization.

  • In this paper, the cycle performance analysis for condensation and evaporation capacity, total work and efficiency of ocean thermal energy conversion power system using R744 ($CO_2$) is presented to offer the basic design data for the operating parameters of this system. The operating parameters considered in this study include superheating and subcooling degree, evaporation and condensation temperature, pump and turbine efficiency. The main results were summarized as follows : The evaporation capacity of R744 increases with superheating and subcooling degree, but decreases with the increasing condensation temperature. The total work increases with superheating and subcooling degree of R744, but decreases with the increasing evaporating temperature. And, the efficiency increases with subcooling and superheating degree, but decreases with the increasing condensation temperature. Therefore, superheating and subcooling degree, evaporation and condensation temperature and pump and turbine efficiency of R744 OTEC power system have an effect on the evaporation and condensation capacity, total work and efficiency of this system. With a thorough grasp of these effect, it is necessary to design the OTEC power cycle using R744.
