  • In the quality assurance check process of DC motor systems, even though the overall sound pressure level is acceptable, there is an incident that subjective evaluation leads to failure in product quality due to annoying noise. This kind of problem may be originated from the manufacturing or assembly process. In this paper, the transient spectral analysis, or the time-frequency analysis is applied to the noise quality problem. For the case study, the cause of annoying noise in the wind shield wiper motor is experimentally analyzed in detail. It is concluded that the defect in the shaft causes the impact noise which is not detectable by steady spectral analysis. Also demonstrated is how the time-frequency analysis is effectively applied to the annoying noise identification of the rotor-gear system.

  • The purpose of the study was to examine the vocational educational system of Egypt, focusing on the effectiveness of the three consecutive cycle-based curriculum and integrated technical education clusters (ITECs) in order to suggest some implications for innovating the current vocational education system of Korea. The vocational education system of Egypt is similar to that of Korea, in terms of general education to go to university and vocational education to go to labor market. However, the Egyptian system is different from the system of Korea in light of the three consecutive cycle-based curriculum that links secondary vocational education, vocational education of college level, and advanced technical and vocational education. In addition, the Egyptian system has adopted the "cluster" approach which integrates technical secondary school, intermediate technical college, and advanced technical college around one physical area so as to promote vocational education in collaboration with regional industries and to guarantee education quality. In the last part, some potential implications were suggested for upgrading the quality of vocational education of Korea based upon the benchmark results of the Egyptian vocational education system and career development of students.

  • The International Organization for Standardization(ISO) is a worldwide federation of national standards bodies. Through ISO Technical Committees(TC), various International Standards are being carried out. Each member body interested in a subject for which a TC has been established has the right to be represented on that committee. ISO collaborates closely with the International Electro-technical Commission(IEC) on all matters of electro-technical standardization. ISO established the ISO 9000 Family standard in 1987, and International Standard ISO 9000-3 was worked by ISO/TC 176, Quality management and quality assurance, Subcommittee 2(SC 2), Quality systems, in accordance with the ISO/IEC Directives, Part 3: 1997 Rules for the structure and drafting of International Standards, Many organizations have applied the ISO 9000-3 for their quality system standard in the software sector. That means that ISO 9000-3: 1991 and ISO 9000-3: 1997 have been used successfully by the software industry as the internationally accepted interpretation of ISO 9001 for the development and maintenance of computer software. Additionally ISO 9000-3: 1997 involved how the software life cycle processes defined in ISO/IEC 12207: 1995, Information Technology - Software Life Cycle Processes related to the requirements of ISO 9001:1994. After having performed full reviews of the WD3, CD1, CD2 and DIS drafts of the future ISO 9001:2000, this document will partly replace the part of ISO 9000-3: 1997 for measurement analysis and improvement of quality management system in computer software industry, as an interpretation for organizations and certification bodies, which will be withdrawn when ISO 9001:1994 is replaced by ISO 9001:2000,.

  • Total quality management has been a focus of concern in recent years since some dissatisfaction with the results from implementation of quality assurance programs in the U.S. Many managerial methodologies and innovation guidelines from academic disciplines have been applied to promote TQM programs in the health field. This paper consists of two folds of aspects: firstly to examine TQM's managerial philosophy by comparing with the newly introduced managerial concepts in Business Reengineering; and then to introduce a method for an integrative way of process analysis, Entity Life-Cycle Diagram (ELCD) modeling. The analysis method was compared with Process Map, which is a well-known method for BR applications. To show effectiveness of ELCD modeling, a case of application was introduced using 'drug' as a target entity. With having TQM issues in mind, the result was reflected in designing Entity Relation Diagrams. The results of ELCD modeling turn out to be helpful in designing database related to quality monitoring, in that many monitoring check points can be identified in a systematic way and that queries cross-sectional over organizational boundaries can be generated with a consistent view focusing on the drug use as a single process. Full evaluation of the analysis method remains to be studied until the completion of the information system under construction. But as long as TQM is based on a process-oriented view and needs supports from information system, ELCD can be one of the appropriate choice as a tool for the process analysis.

  • Clients ought to Appropriate the cost of quality management for contractors based on Construction Technology Management Act. The costs of safety management and environment reservation are separately estimated. and the quality management cost is added up to secure the construction quality required on sites. However, the sufficient cost for quality management was not allowed to the contractors, due to the viewpoints of the clients that the quality management should be one of the duties of contractors. In addition, an Account-related legislation enacted a provision of the labor cost of quality management as the one that should be included in the indirect labor cost. From the continuous survey the quality management cost is currently estimated by 0.2% of the total project cost and the contractors protest the portion of the quality management cost is insufficient. Thus, this paper aimed to provide the bases of estimation of the actualized quality management cost considering the viewpoint of contractors.

  • Human in vitro fertilization and embryo transfer (IVF-ET) program is a general procedure for infertile couples since first successful delivery on 1978 in UK and Korean first on 1985. Recently in Korea, more than 42,000 cases per year of IVF-ET were performed and showed good pregnancy rates compared worldwide data. The human IVF-ET procedure use many consumables, such as ovum pick-up (OPU) needles, centrifuge tubes, culture dish, ICSI pipette, culture media and ET catheters. Major of these materials are supported by the global companies. Thus, Korean IVF-ET program might be placed unstable situation by global economical risks. These uncertain problems could be overcome by the domestic production of IVF-ET materials and consumables. Two times questionnaires for Korean clinicians and researchers about the domestic production were performed and analyzed. Many of them requested domestic OPU needles, ET catheters, culture media and ICSI pipettes under good quality control and quality assurance system. This trial may be contributed to industrialization and to global competence of Korean IVF-ET program. The results of this survey can be provide a fundamental base for development and production of domestic materials and consumables for human IVF-ET program.

  • This paper discusses the influence on long-tenn predictions of the ship response in ocean by using the Global Wave Statistics data, GWS, and wave information from the remote sensing satellites. GWS's standard scatter diagrams of significant wave height and zero-crossing wave period are suggested to be corrected to a round number of 0.01/1000 fitted with a statistical analytic model of the conditional lognormal distribution for zero-crossing wave period. The GEOSAT satellite data are utilized which presented by I. R. Young and G. J. Holland (1996, named as GEOSAT data). At first, qualities of this data are investigated, and statistical characteristic trends are studied by means of applying known probability distribution functions. The wave height data of GEOSAT are compared to the data observed onboard merchant ships, the data observed by measure instrument installed on the ocean-going container ship and so on. To execute a long-tenn prediction of ship response, joint probability functions between wave height and wave period are introduced, therefore long-term statistical predictions are executed by using the functions.

  • The purpose of this study is to provide the comparative study results for the purpose of the developing continuing professional educational systems for Korean pharmacists. The professional continuing educational systems of the UK, USA, Japan and Korea were analyzed. General Pharmaceutical Council in UK controls the pharmacy professions for the protection of the health of the citizens in UK and certifies the schools of pharmacy and the continuing education providers. The USA and Japan have the several accreditation bodies for the pharmacy education and the continuing pharmaceutical education. However, the quality assurance systems in Korea for the continuing education and specialty programs are not implemented, yet. The renewal system of the pharmacist license should be introduced like the health care providers like doctors to improve professionalism. Finally, it is recommended that all of these things should be done by a single administrative authority such as Korean Accreditation Council for Pharmacy Education.
