  • Purpose: This study aimed to use the DACUM analysis technique and identify the job description among nurses of the Central Supply Department, in order to clarify their duty and task descriptions, identify the characteristics of job. Methods: Through a DACUM workshop, job descriptions, and the job duties and tasks were derived. A total of 150 nurses from the Central Supply Departments of medical Institutions over 100 beds were surveyed using drafting and a job analysis table. Individual jobs' frequency, importance and difficulty were measured using a 3-point scale, and the results were analyzed using SPSS. Results: The nurses' job in the Central Supply Department consisted of 13 duties and 64 tasks. Duties with highest importance and difficulty was 'sterilization assurance system', the second was 'employee safety management' and the duty with highest frequency was 'manage packaging before sterilization'. Conclusion: This study clarified the types of nursing jobs in the Central Supply Departments, as well as identified the job characteristics and status in the given setting. Given the sterilization assurance system for preventing hospital infection, and safety management for ensuring work environment safe were found to be important duties, it is suggested for the department to stress those important jobs for managing hospital safety.

  • This study aims to derive the life service supply structure in rural areas of Jeollabuk-do through the analysis of the centrality of life service in Eup/Myeon central area. In addition, mutual relationship between the settlement system in rural areas and the current status of the supply of living services in Eup/Myeon areas were also analyzed. In particular, in this study, the entire administrative districts of Jeollabuk-do are intended to be established as a single wide area unit, breaking away from the current status of living service supply at the Si/Gun level. This study mainly conducted with three points. First, the spatial range of Eup/Myeon central districts with centrality in terms of living service supply was established. Second, the hierarchical structure of the living service supply system in the rural areas of Jeollabuk-do was investigated through the analysis of the living service supply level based on the centrality and geographical distribution in Eup/Myeon central districts. Based on the analysis results, the central place system of rural areas in Jeollabuk-do was established in terms of living service supply. Third, through the analysis of the living service functions distributed in the central area, and the type of living service supply by hierarchy was identified.

  • Background : Because hospitals had to faced with financial hardship, we have to have more effective hospital management. In this study, we tried to improve job performance and to reduce cost maintaining safety in fields of patients care. Methods : Central Supply Room(CSR) staffs taught strategy of material cost reduction to middle level managers and staffs 14 times. All staffs and voluntary service workers, working in 33 nursing units, participated in this activity. We developed questionnaire to check the degree of participate in cost reduction activity and job performance in CSR, and quality improvement in the wards. Two hundred questionnaires were distributed and 197 returned. Results : Because CSR staffs developed new items and every item was managed at each department, stocks of each department were reduced. Overall, by comparing before and after cost reduction activity, almost 1.2 billion won reduced for one year. Staffs' loyalty and spirits of cost reduction were improved by changing clothes and duty environment. Furthermore, these activity improved patients' satisfaction. Conclusion : We suggest that CSR activity in a university hospital contributes to improve job performance and to reduce cost without any problem in patient care.

  • There are two hydrogen supply systems which are central and distributed supply. Central supply system may be cost-effective but huge supply infra cost is needed. For cost-effectiveness, hydrogen supply with existing natural gas pipeline has been focused in Europe. From the analysis results in this study, hydrogen supply method with existing natural gas pipeline is the better for environmental availability including green house effect.

  • We investigate the plausibility of mass return, from stellar mass loss processes within the central ~100 pc region of the Milky Way (the inner nuclear bulge), as a mass supply mechanism for the Circumnuclear Disk (CND). Gas in the Galactic disk migrates inward to the Galactic centre due to the asymmetric potential caused by the Galactic bar. The inward migration of gas stops and accumulates to form the central molecular zone (CMZ), at 100-200 pc from the Galactic center. It is commonly assumed that stars have formed in the CMZ throughout the lifetime of the Galaxy and have diffused inward to form a 'r-2 stellar cusp' within the inner nuclear bulge. We propose that the stars migrating inward from the CMZ supply gas to the inner nuclear bulge via stellar mass loss, resulting in the formation of a gas disk along the Galactic plane and subsequent inward migration down to the central 10 pc region (CND). We simulate the evolution of a gas distribution that initially follows the stellar distribution of the aforementioned stellar cusp, and illustrate the potential gas supply toward the CND.

  • Energy consumption is an important index in mobile ad hoc networks. Data packet transmission increases among nodes, particularly in big data communication. However, nodes may be unable to transmit data packets because of energy over-consumption. Consequently, information may be lost and network communication may block. While opportunistic network is a kind of mobile ad hoc networks, researchers do not focus on energy consumption in opportunistic network communication. This study proposed an effective sensor energy supply scheme that can be applied in opportunistic networks. This scheme considers nodes sensor requests and communication model. In this scheme, nodes do not only accomplish energy supply in communication, but also extend communication time in opportunistic networks. Compared with the Spray and Wait algorithm and the Binary Spray and Wait algorithm in simulations, the proposed scheme extends communication time, increases data packet transmission, and accomplishes energy supply among nodes.

  • Heating and air conditioning system is changing rapidly from the traditional HVAC central supply system to the individual supply system with electrical heat pump system (EHP) in Korean school buildings. The individual supply system has advantages to turn on and off individually and to adjust the thermal comfort separately, but energy is wasted in the unoccupied classroom when the last leaving occupant does not turn off the controller. If the controller is to be off automatically while the classroom is not in use, energy consumption would decrease dramatically. This project aims to cease the unnecessary EHP supply in vacant classroom by inputting the class schedule from the central control room to reduce the energy-spending. Experimental measurements were carried out between the controlled classroom that is turned off when not in use and the uncontrolled room that is turned on continually. Occupant's comfort and energy consumption were measured and compared between the controlled case and the uncontrolled case. The energy consumption of controlled classroom case is 30-60% less than that of the uncontrolled classroom case. This result shows that controlling the cooling supply for the unoccupied classroom using the class schedule can decrease the energy consumption remarkably. This supply control system can be used to conserve energy in school structures like universities.

  • The emergency AC power supply system of the nuclear power plant is designed to supply the power to the nuclear power plant at the emergency operating condition. The safety function of the diesel generator at the nuclear power plant is to supply AC electric power to the safety system whenever the preferred AC power supply is unavailable. The reliable operation of onsite standby diesel generator should be ensured by a condition monitoring system designed to maintain, monitor and forecast the reliability level of diesel generator. The purpose of this paper is to improve the existing ultrasonic sensor used for condition diagnosis of engine fuel pump and cylinder head for the accurate diagnosis in actual engine condition of emergency diesel generator(EDG). As a result of this study, we could design and develop much more reliable ultrasonic sensor than existing ones.
