The purpose of this study is to develop evaluation indicators for academic libraries in Korea. The evaluation model developed in this research consists of three elements:(1) Confirmation of evaluation methods, procedures and criteria,(2) Development of qualitative and quantitative evaluation indicators, and(3) Assessment of the applicability and feasibility of those indicators. Evaluation indicators were developed to measure a basic state, a common use of library resources, specialized services, and user satisfaction for academic libraries. To test the feasibility and applicability of those evaluation indicators, a pilot assessment of academic libraries was conducted in 2010.

The purpose of this paper is to examine the differences of user´s satisfaction of development elements of natural recreation forest(NFR) developed by public and private bodies in order to answer the research question: What is the differences of user´s satisfaction of development elements of NFR\ulcorner After reviewing the literature, mechanism of outdoor recreation, and development elements in NRF, we constructed the conceptual framework and have formulated the hypothesis of this research. We had obtained data through a questionnaire, which surveyed 584 visitors at 10 of the 72 natural recreation forests in Korea in 1999. We have analyzed the data using he descriptive statistical method, the mean difference test, and logistic regression method. We have found that 1) all the development elements have turned out to be significantly different from the mean difference test, 2) the two elements of atmosphere and activity have turned out to be statistically significant in determining the difference of NFR developed by public and private body in logistic regression analysis while user´s satisfaction in recreational resources, facilities and service make no differences between public and private NRF, 3) the higher the degree of user´s satisfaction in atmosphere and activity at NFR, the more the NFR developed by private body, and 4) their relative contribution of atmosphere and activities on whether the NFR is developed by public or private body have been turned out to have 0.258 and 0.242 respectively, which have a similar importance. The research results suggest that a guideline for the creation of marketable NFR by public and private developer, and development of use-programs and recreational atmosphere be recommended in the planning and development process of NRF. The approach and anlaysis method adopted by this research is highly useful for an evaluation of NRF developed by the tow bodies and development of devices for increasing user´s satisfaction and marketing positioning of NRF by the tow developers. It is recommended that more empirical study on individual development elements affecting user´s satisfaction be performed in the future.

Flow accelerated corrosion (FAC) of the carbon steel piping in nuclear power plants (NPPs) has been major issue in nuclear industry. Rotating cylinder FAC test facility was designed and fabricated and then performance of the facility was evaluated. The facility is very simple in design and economic in fabrication and can be used in material and chemistry screening test. The facility is equipped with on line monitoring of pH, conductivity, dissolved oxygen(DO), and temperature. Fluid velocity is controlled with rotating speed of the cylinder with a test specimen. FAC test of SA106 Gr. B carbon steel under 4 m/s flow velocity was performed with the rotating cylinder at DO concentration of less than 1 ppb and of 1.3 ppm. Also a corrosion test of the carbon steel at static condition, that is at zero fluid velocity, of test specimen and solution was performed at pH from 8 to 10 for comparison with the FAC data. For corrosion test in static condition, the amount of non adherent corrosion product was almost constant at pH ranging from 8 to 10. But adherent corrosion product decreased with increasing pH. This trend is consistent with decrease of Fe solubility with an increase in pH. For FAC test with rotating cylinder FAC test facility, the amount of non adherent corrosion product was also almost same for both DO concentrations. The rotating cylinder FAC test facility will be further improved by redesigning rotating cylinder and FAC specimen geometry for future work.

In general, similar or previous projects are mainly referred to in order to derive operational test and evaluation(OT&E) items after acquiring weapon system. The idea that a more systematic method is needed is spreading because some of OT&E items derived in this process are redundant or unnecessary. Therefore, in this topic, we plan to use WBS, a tool that classifies components into a hierarchical structure and manages development easily to achieve the weapon system development goal. In addition, the WBS tool is applied to the medium-sized standard vehicle project, which is currently being research and developed, to effectively derive OT&E items. As a result of deriving OT&E items by applying WBS to the vehicle development field and electric devices of the medium-sized standard vehicle project, the operability and relationship were judged early, and then contents of the evaluation items could be written substantially while working on environmental adaptability. In the future, it is judged that the efficiency will be increased if the method discussed in this paper is applied when deriving the OT&E items from the R&D development project.

The C-ITS requires the lane level positioning of the vehicle in the land transportation environment, and it is most effective to utilize the GNSS. In the precision positioning system based on satellite navigation, the evaluation of dynamic environment of lane level positioning performance should be accompanied and the evaluation system configuration should be preceded. In this paper, we selected performance indicators, assessment equipment, and reliability of reference equipment for evaluation of precision positioning user systems based on the GNSS. The performance evaluation system described above is applied to a real system, and the performance evaluation tool developed for the evaluation system is described. The numerical performance evaluation was carried out based on the data collected by carrying out the actual testbed driving. The performance evaluation by the actual driving trajectory and driving image comparison was performed to derive and analyse the evaluation results of the vehicle lane level positioning user system.

In this paper, in order to apply Prognostics and Health Management(PHM) to an electronic system or circuit, a circuit capable of detecting and predicting defect characteristics inside the system or circuit is implemented, and the results are described. In the previous study, we demonstrated that the frequency of the amplitude of S-parameter changed as the circuit defect progressed. These characteristics were measured by network analyser. but in this study, even if the same defect detection method is used, a circuit is proposed to check the progress of the defect, the remaining time, and the occurrence of the defect without large measurement devices. The circuit is designed to detect the change in impedance that generates changes of S-parameter, and it is verified through simulation using the measurement results of Bond-wires.

The purpose of this study is to develop the pattern of safety clothes used at flat or mountainous areas and to identify the pattern of safety clothes by conducting experimental evaluation of virtual wear. Three subjects were selected, based on fire fighters' physical constitution. A prototype design for safety clothing was determined after in-depth interviewing of professionals and surveying of Forest service staff and related agency. Wearing test should be carried out in the order of pattern making, virtual and real wearing evaluation. For data analysis, technical statistical values should be obtained by using body measurements of subject, frequency analysis and T-test. The jacket is designed to have a front extension and the entire length of clothing enough for wearer to put on it over ordinary shirts or sweater. The collar of jacket is of round type. Cyber reality enables to identify the movement and activity of virtual fitting model and to find out errors or problems in safety clothing prior to on-the-spot wear test, thus raising the precision level of pattern. There was significant difference between real and virtual fit preference. The results show that the virtual try-on system need the development of a specific style.
