Purpose: This study examined a comprehensive model for assessing the success probability of electric vehicle (EV) commercialization in the Korean market. The study identified three risks associated with successful commercialization which were technology, social, policy, environmental, and consumer risk. Research design, methodology: The assessment of the riskiness was represented by a Bayes belief network, where the probability of success at each stage is conditioned on the outcome of the preceding stage. Probability of success in each stage is either dependent on input (i.e., investment) or external factors (i.e., air quality). Initial input stages were defined as the levels of investment in product R&D, battery technology, production facilities and battery charging facilities. Results: Reasonable levels of investment were obtained by expert opinion from industry experts. Also, a survey was carried out with 78 experts consisting of automaker engineers, managers working at EV parts manufacturers, and automobile industry researchers in government think tanks to obtain the conditional probability distributions. Conclusion: The output of the model was the likelihood of success - expressed as the probability of market acceptance - that depended on the various input values. A model is a useful tool for understanding the EV industry as a whole and explaining the likely ramifications of different investment levels.

The purposes of this study were to identify leadership competences of rural leaders and to analyze leadership competency of leaders. The study carried out by questionnaire and focus group interview on expert panels. To analyze leadership competency, the data was collected from 273 rural leaders by stratified random sampling. SPSSWIN/ver10 program was used for analyzing data with t-test and IPA method. The study suggests twenty low types of leadership competences which were information, vision, decision making, motivation communication, education residents, managing residents, loaming, flexibility, problem solving, presentation program management, customer orientation service knowledge, making relationship, creative idea, business understanding, brand development, conflict resolution negotiation, assessment, business management, coaching and feed back. Whereas leaders with middle school educational career required developing program management, maintaining achievement and benchmarking, leaders with high school were morel likely to develope self-learning, to benchmark their knowhow and brand development competency. Whereas leader with less low years experiences as leader have been considered as developing coaching/feedback brand development and program development, leaders with more five years as leader should consider developing benchmarking, resident education, and brand development. The study suggests that the extension agents on public should develop leadership program according to the competency differences of leaders.

The pressure tube is a major component of the CANDU reactor, which supports nuclear fuel bundle. In order to complete the integrity evaluation of pressure tube, expert knowledge, iterative calculation procedures and a lot of input data are required. More over, results of integrity assessment may be different according to the evaluation method. For this reason, an integrity evaluation system, which provides efficient way of evaluation with the help of attached database, was developed. The present system was built on the basis of 3D FEM results, ASME Sec. XI, and Fitness For Service Guidelines for CANDU pressure tubes issued by the AECL (Atomic Energy Canada Limited). The present system also covers the delayed hydride cracking and the blister evaluation, which are the characteristics of pressure tube integrity evaluation. In order to verify the present system, several case studies have been performed and the results were compared with those from AECL. A good agreement was observed between those two results.

Microscopic examination of the morphology of wear debris is an accepted method for machine condition and fault diagnosis. However wear particle analysis has not been widely accepted in industry because it is dependent on expert interpretation of particle morphology and subjective assessment criteria. This paper was undertaken to analyze the morphology of wear debris for machine condition diagnosis of the lubricated moving surfaces by image processing and analysis. The lubricating wear test was performed under different sliding conditions using a wear test device made in our laboratory and wear testing specimen of the pin-on-disk-type was rubbed in paraffine series base oil. In order to describe characteristics of debris of various shape and size, four shape parameters (50% volumetric diameter, aspect, roundness and reflectivity) have been developed and outlined in the paper. A system using such techniques promises to obviate the need for subjective, human interpretation of particle morphology in machine condition monitoring, thus to overcome many of the difficulties in current methods and to facilitate wider use of wear particle analysis in machine condition monitoring.

This research aims to contribute to the discipline of knowledge management (KM) in Higher Education (HE), and is conducted using the case of the study programme (SP) for Integrated Academic Studies (IAS) of Technics and Informatics (TI). A deduction-induction methodology is applied, using a Plan-Do-Check-Act (PDCA) approach to design a suitable KM concept for making improvements to the SP IAS TI on the standardisation platform. Based on the application of the International Classification of Standards (ICS), the research analyses the correlations and competences acquired during the courses within the accredited TI study programme of two-course studies. On the basis of the results of a comparative analysis of the developmental learning process and educational goals, it is shown that knowledge management in correlation with standardisation leads to the improvement of study programmes in the upcoming accreditation cycle on the standardisation platform. Frequent innovations within standardised thematic fields (daily, weekly, monthly, etc.) indicate the need for appropriate changes to the SP. The contribution to KM is through an original analysis of annual samples of more than 90,000 standardised sources in correlation with the TI study programme. Expert System (ES) modelling and the original results enable an analogous contribution to the future KM of other SPs.

Purpose: The purpose of this study was to evaluate the applicability of the evidence based guideline for prompted voiding by Lyons & Specht (2001) in National Guideline $Clearinghouse^{TM}$ for use in Korea based on the experts' opinions. Method: The target expert group consisted of 8 registered nurses, 6 physicians, and 5 nursing professors who are experts in urinary incontinence. This study used a questionnaire survey. The appropriateness, applicability, and the present application of each recommendation in the guideline were analyzed with descriptive statistics using the SPSS program, with content analysis based on the experts' opinions. Result: The scores on each recommendation's appropriateness showed the high degree of agreement among nurses, physicians, and nursing professors. However, the recommendation for 'use of oxybutinin' showed the lowest score as 5.89. It was notable that the most recommendations scored lower for applicability compared with appropriateness. The reasons for lower scores for applicability were the lack of clinicians' knowledge of assessment and management, and the lack of resources in clinical settings in Korea. Conclusion: This study will augment the understanding of the actual urinary incontinence management in Korean clinical settings and can be used as the baseline data for further study of tailoring international guidelines into local and national clinical settings.

Purpose: The purpose of this study was to evaluate the correct use of inhalers and to examine the patients characteristics affecting correct use of inhalers in patients with obstructive pulmonary disease. Method: Subjects were 280 patients with obstructive pulmonary disease who visited the internal pulmonary outpatient departments in 2 university hospitals in Korea. Inhaler use of each patient was assessed using a checklist recommended by the National Asthma Education and Prevention Program Expert Panel. Result: Most subjects used a DPI or MDI. The overall mean score of correct use was 72.09. Most subjects responded they knew well how to use their inhalers. Most frequent error was 'not fully exhaling before inhalation'. A younger age, higher educational level, living with family, and awareness of inhaler use were significantly associated with correct use of inhalers. Conclusion: The findings of this study showed that most of patients were unable to use inhalers correctly even though they had prior educational experiences. Regular assessing of inhaler use and adequate inhaler education considering patients characteristics by nurses are needed.

Marine traffic safety of the Vung Tau Waterway, from port limit to Ganh Rai Gulf, plays a crucial role in the economic development of the important triangular economic zone in the south of Vietnam: Ho Chi Minh City, Dong Nai Province, Ba Ria-Vung Tau Province. This paper uses the IWRAP Mk2 program to assess marine traffic safety and shows that in the area there are three parts of fairway have highest risk of collision (from buoys No. 8-9 to buoys No. 1-2 of the Song Dinh fairway; from buoy No. 0 to buoys No. 8-9 and from buoys No. 6-9 to buoys No. 8-9A of the Sai Gon-Vung Tau fairway) and the two areas have highest risk of grounding (the Vung Tau coastline from Ganh Hao to Sao Mai and an area in the Ganh Rai Gulf). In addition, the result of a questionnaire survey on a group of Pilots shows that wind, current and rain/fog have considerable negative effect to ship handling of large vessels in this area. This paper's results will be used in the further research to discover solutions for improving marine traffic safety in the Vung Tau Waterway.
