Purpose: Purposes of this study were to identify non-value-added nursing activities (NVANAs) and to estimate the amount of time spent on NVANAs among total nursing activities. Methods: Non-value-added nursing activities were identified though the use of a focus group. The nurses in the focus group were nurses working in a tertiary hospital. They discussed possible activities that could be NVANAs. Based on the focus group discussion, a pilot study was done to examine the actual occurrence of NVANAs in clinical settings. Results: The focus group discussion showed that NVANAs occurred in ten categories of nursing performances including communication with physicians, communication with other departments, medications, equipment/supplies, nursing records, tests, admission, discharge, and transfer. Direct nursing activities accounted for 35.5% of total nursing activities while indirect nursing activities accounted for 64.5%. Of indirect nursing activities, 16% were NVANAs. Most NVANAs were related to communication and equipment/supplies. Conclusions: To improve the quality and efficiency of nursing activities, it is necessary to identify NVANAs and their causes. Results of this study suggest that improvement in the work process and nursing unit structure, support for equipment/supplies, and effective communication are needed to reduce NVANAs in tertiary hospitals in Korea.

Recently, with a high demand for the construction and remodeling of libraries, and the rapid increase in the number of libraries during the last two years, the concern and need for library goods is also increasing sharply. The purpose of this study is to develop a new classification scheme of library goods by clarifying the terminology which could provide an accurate information on library goods and allow for their smooth circulation. In this study, library goods are defined as all kinds of products required for effectively collecting, organizing and providing services with library materials, and classified into library equipments and library supplies. The term, library equipment is principally used for those things that do not wear out within a certain time period, such as furniture and machinery. Library supplies refer to those things that are expendable. As the terminology is clarified, the classification scheme can be further refined. Library equipment, for example, can be classified as furniture, library system solutions, and computers and multi-media tools. Library supplies can be classified into library organization and repair supplies, sign systems, and miscellaneous articles. Finally, six major categories which include 117 different items are presented.

Purpose: This study was conducted to assess the incidence and characteristics of pressure ulcer in relation to the type of equipment and supplies(EnS) in intensive care unit(ICU). Method: By using secondary data analysis and descriptive investigation, 29 patients of pressure ulcers caused by EnS were examined from January 2013 to December 2015, at the advanced general hospital located in Gyeongsangnam-do. The subjects were aged 19 years and above and had been in the ICU for more than 3 days. The data were analyzed using the SPSS WIN 23.0 with frequency, percentage, and mean and standard deviation. Result: The incidence of EnS-related pressure ulcers was 3.71%. The EnS-related causes for pressure ulcers were endotracheal tube(31.03%), restraint(20.69%), and neck brace(10.34%). The longest use of EnS was oxygen tube(29 days). EnS that were possibly causing pressure ulcer for one day were restraint(upper extremities), endotracheal tube(oral and face), and oxygen mask(ear and nose). Conclusion: This study has been limited to secondary data analysis that may result in missing records of pressure ulcers related to EnS in ICU. However, the analysis of this research is expected to contribute to the development of nursing interventions to clarify the guidelines for the prevention of pressure ulcers related to EnS in ICUs.

Purpose: Although the price reduction policy is established for military supplies, it is more focused on general military items. Therefore, it is hard to apply the current price reduction policy directly to the major weapon system. The purpose of this study is to develop an evaluation model which generates appropriate outputs for price reduction of military supplies. Methods: To improve the current policy, we first analyze the relevant policies of price reduction of similar organizations. We gather the opinions of related organization through survey including DAPA, Logistics Command, DTaQ and Defense industry companies. Then, we develop a price reduction model based on the analytic hierarchical process(AHP) method to find out important factors for price reduction. Results: The results of AHP analysis show that the important factors when applying price reduction of military supplies. From the analysis, the proposed method effectively generates the amounts of price reduction for the nonconformance items. Conclusion: The results of this research will be used as guidelines to improve military supplies policy of price reduction.

A test simulator is needed to develop a fuel quantity measurement system that takes into account the roll and pitch motion of the aircraft. In this paper, we develop a test simulator that consists of attitude simulation equipment, fueling equipment, and data storage equipment. The attitude simulation equipment simulates the aircraft attitude. It is manufactured to operate pitch angle and roll angle movement. The fueling equipment supplies fuel to the supplementary fuel tank. The data storage equipment collects and stores the measured data. We also develop an automation software that operates the test simulator and collects data automatically. The test simulator has been automated to prevent testers from being exposed to toxic fuel. Through automation software, the collection period is reduced by one quarter compared to manual collection. The developed fuel quantity measurement system is verified through the test simulator.

Wargame is a simulated military operation with certain rules, specifications, and procedures, in which soldiers can virtually and indirectly experience the war. The ROK Navy operates the Cheonghae model, a training wargame model for helping commanders and staff master the procedures for conducting the war. It is important for commanders, staff and analysts to know whether a warship can perform its missions and how long it can last during a war. In existing model, the Cheonghae, the probability of kill of a warship is calculated simply considering the number of tonnage without any stochastic elements, and the warship's mission availability is also determined based on predetermined values. With this model, it is difficult to get a value of the probability of kill that makes sense. In this dissertation, the author has developed a probabilistic model in which the warship vulnerability data of ROK-JMEM can be used. A conceptual model and methodology that can evaluate the mission performance of personnel, equipment, and supplies has been proposed. This can be expanded to a comprehensive assessment of wartime warship loss rates by integrating damage rates for personnel, equipment, and supplies in wartime.

The purpose of this paper is to present a model for operating an emergency power system(EPS) that can secure a sufficient power supply used in case of a fire by analyzing the status of power supplies for emergency and firefighting operations. Investigations on the one of the causes of the operational failure of firefighting systems show evidence of EPS. Generally, when power to a building is interrupted, EPS supplies the emergency load(excepted firefighting load) first. When a power outage and a fire occur simultaneously, the EPS must be able to supply both the emergency load and the firefighting load, especially the firefighting load to the end. However, in order to save construction costs, emergency power generators in apartment, commercial, and business buildings can satisfy only one of the required loads. In cases like this, when a power outage and a fire occur simultaneously, there is a danger of firefighting equipment not operating due to insufficient power supply from the emergency generator. Therefore, an EPS must have a reserved firefighting power that can supply both the firefighting and the emergency load. Such EPS, when faced with a danger of an overload, will shut down the supply to all or part of the emergency load, thus securing a continuous power supply to the firefighting equipment. The generator power system with reserved firefighting power (RFP) will also have an indicator to show that the selective control is being used. General power generation systems for emergency load and firefighting load were found to have a demand factor of 50-60% with a lump. However, when installing an EPS, the builders must choose the higher demand factor suggested according to the official approval demand factor of the building.
