New product development (NPD) is defined as the transformation of a market opportunity and a set of assumptions about product technology into a product available for sale. Managers charged with project selection decisions in the NPD process, such as go/no-go choices and specific resource allocation decisions, are faced with a complicated problem. Therefore, the ability to develop new successful products has identifies as a major determinant in sustaining a firm's competitive advantage. The purpose of this study is to develop a new evaluation model for NPD project selection in the high -tech industry using support vector machines (SYM). The evaluation model is developed through two phases. In the first phase, binary (go/no-go) classification prediction model, i.e. SVM for high-tech NPD project selection is developed. In the second phase. using the predicted output value of SVM, feasibility grade is calculated for the final NPD project decision making. In this study, the feasibility grades are also divided as three level grades. We assume that the frequency of NPD project cases is symmetrically determined according to the feasibility grades and misclassification errors are partially minimized by the multiple grades. However, the horizon of grade level can be changed by firms' NPD strategy. Our proposed feasibility grade method is more reasonable in NPD decision problems by considering particularly risk factor of NPD in viewpoints of future NPD success probability. In our empirical study using Korean NPD cases, the SVM significantly outperformed ANN and logistic regression as benchmark models in hit ratio. And the feasibility grades generated from the predicted output value of SVM showed that they can offer a useful guideline for NPD project selection.

In order to ensure the safety of the large-scale public facilities, the analysis of EMC(ElectroMagnetic Compatibility) of electronic systems included in the facilities is very necessary. The reason is that the system-level EMC of the facility could be not guaranteed, even if individual equipments included in the facility are satisfied with their EMC requirements. As a result, the system-level evaluation and analysis of EMC should be carried out in order to establish the reliable operations of safety and mission-critical electronic systems. This paper analyze the relevant legal systems of domestic and other countries, and furthermore case studies of system-level EMC approaches were analyzed in the specific applications of electric railways, building, automobile, petroleum refinery systems. And the introduction of related systems in Korea is proposed, and main parts and problems to be looked at each proposed measures are discussed. The results are expected to be utilized in the introduction of the system-level EMC engineering, and contributed in national security and the protection of people's life, body and their properties.

The aim of this study was to evaluate the readability and suitability of patients' education materials on DM. A total of 34 materials on DM from public health centers, general hospitals, and internet web sites were evaluated for readability by 'graded system of vocabulary', and suitability by 'The Korean version of SAM(Suitability Assessment of Materials)'. On the average, 28.3% of 1st grade reading level words, 27.1% of 5th grade level and over were included in educational materials. For suitability, 6(17.6%) were judged superior, 20(58.8%) adequate, 8(23.6%) inadequate. The reading level of the materials was higher than the recommended reading level(6th grade reading level). For suitability, most of materials were inadequate in some of items such as 'summary or review included', 'context given', 'interaction used'. It is proposed that in the development of patients' educational materials, health literacy of target population should be considered.

The aim of this paper is to establish the evaluation system of port logistics of Incheon using the QFD(Quality Function Deployment) model. The research methodology is consisted of four phases. The first step is to investigate the important factors consisting the port logistics of Incheon and then calculate the weighting of factors by Analytic Hierarchy Process (AHP). The second step is to draw out the degree of inter-relation among factors by Fuzzy Subordination Relations (FSR). At the third step, the established system through the QFD method using results of the first and second steps will be used to evaluate and diagnosis the level of port logistics of Incheon. Finally, the sensitivity analysis will be performed and the degree of improving port logistics will be presented according to the rising the relevant factors.

This study aimed to develop self-diagnosis tools to evaluate the common competence level of public library librarians, apply them to actual public library librarians, and analyze the factors of competency value evaluation through empirical research methods. To this end, the study modify the existing capacity value evaluation indicators of librarians from a public library perspective and conducted a survey to self-diagnose the common capabilities of public library librarians. As the results of analysis showed that librarians of public libraries themselves think that the level of core competence that professional librarians should acquire is relatively higher than the average. Among the overall capabilities of librarians, the average of the 'librarians' behavior and attitude' area was the highest, followed by the 'librarians' skill' and 'librarian's knowledge' areas. The study suggested to strengthen the capacity of public library librarians for various duties, the re-education system for librarians should be established, and a systematic system for promoting librarians' duties as professionals, and a personnel system for professional development.

It is known that human factors account for 80 percent of all railway accidents. To reduce human errors must be the most efficient shortcut to railway safety. For public transportation employees like railway, the more delicate safety management should be executed in individual level. However, there are rarely efforts to improve safety performance of workers who are the subject operating the railway system. This paper develops a hierarchy model to evaluate the human safety performance in railway industry. To evaluate the model, AHP (Analytic Hierarchy Process) methodology is adopted. The hierarchy model is composed of four levels which are objective, two criteria, specific factors of criteria, and rating scales. In addition, since employees for evaluation are over 10, the pairwise comparisons for rating scales are carried out by the absolute measurement. We explore the applicability of AHP to the performance evaluation of railway safety workers by an example and also investigate the changes of alternatives that are railway employees according to the changes of human characteristic which is one of criteria.
