  • The last decade of this centry is now the accepted birth date of that sub-discipline of pharmacy that is now called 'biopharmceutics'. Wagner defines biopharmaceutics 'as the study of the influence of fomulation on the therapeutic activity of a drug product.' More specifically, he states that biopharmaceutics encompasses the study of the relationship between the nature and intensity of the biological effects observed in animals or man and the following factors: 1. The nature of the form of the drug (ester, salt, complex, etc). 2. The physical state, particle size, and surface area. 3. Presence or absence of adjuvants with the drug. 4. The type of dosage form in which the drug is administered. 5. The pharmaceutical process (es) used to make the dosage form. The philosophy inherent in this definition has revolutionized our thinking with respect to product development, quality control, and to the practice of pharmacy itself. Althoughthe the emphasis herein will be on quality control, the interrelationship between this and the other areas of pharmacy will be evident. The principles of quality control dictate that a wide variety of techniques be used to evaluate the quality of a dosage form. Since quality must be built into a dosage form, the pharmaceutical scientist begins the process at the research stage, continues it during the production stage, and ends it by applying the tests and procedures established by parmacopeial commissions. These stages are usually separate and distinct and, because of this, product quality has become synonymous with compliance with pharmacopeial specifications.

  • Objectives: The purpose of this study was to examine the oral health care of oral prophylaxis practice lab visitors, their recognition of oral care supplies, their use of oral care supplies by type, and influential factors for their recognition and use of oral care supplies. Methods: The subjects in this study were 275 people who visited an oral prophylaxis practice lab at a university located in an urban community. The visitors were respectively interviewed from March to June, 2016, and the data from 260 respondents who properly responded were analyzed, and data from 15 visitors who provided incomplete responsees were excluded. Statistical analysis was performed using the nonparametric tests, mann-whitney test and kruskal-wallis test, and multiple regression analysis using SPSS. Results: The mean score of oral care products was 2.25, the average degree of use was 0.09, and dental floss (0.29) was the most used oral care product. There was a significant difference between the groups according to gender (p<0.001), age (p<0.001) and marital status (p<0.001). Factors influencing the perception of oral care products were experience in brushing education and experience in oral care products education. Conclusions: The recognition of the oral prophylaxis practice lab visitors about oral care supplies and their use of the supplies were under the influence of oral health education. Therefore, sustained efforts should be directed into the development of efficient oral health care education programs that can inform people about the importance of oral health care, publicize oral care supplies, and encourage the use of these supplies.

  • This paper advances the thesis that the barrier separating curriculum theorists and practitioners is more than a difference in experiential and methodological orientation and is in part a product of a lack of appreciation of the complexities involved in curriculum development and dissemination. Discussed here is the possible use of engineering theory to facilitate meaningful communication and understanding about products and development. This work is an extension of the observation that curriculum development and dissemination can be characterized as an engineering process and shows how engineering theory provides connectivity between the multiple embedded domains of theory and of practice. To illustrate the thesis this paper offers an analysis of the Developmental Approaches in Science, Health, and Technology (DASH) program that has employed engineering theory in curriculum construction and dissemination. In this study, the role and place of engineering theory as applied to the DASH program is discussed to show how the components were designed and assembled into a fully functional curriculum and dissemination system. Engineering theory is presented as an interfacing organizer with the potential to facilitate meaningful communication between theorists and practitioners.

  • In order to survive worldwide competition, today's industries are experiencing strong pressure to introduce higher quality products with lower cost and shorter lead-time. Therefore, the role of design in the process of product development is increasing in significance. In this research, two methods for improving the design capability are proposed: construction of design environment and design automation using 3D CAD system. The designers and design process are the core of product design using 3D CAD system. In order to maximize the design performance, construction of the design environment including selection of a suitable system, designer training for best use of the system, establishment of an efficient design process, and stabilization of the environment are required. A method is suggested to construct design environment by systematizing the contents of the projects and consulting experiences carried out for various categories of business such as electronic devices, motorcycles, electricity parts, sanitary wares, injection molds, and die casing molds. Design automation helps reduce tedious and time-consuming jobs, simplify complicated and error-prone modeling and drawing works to shorten the lead time and improve the product quality. To develop a design automation system, understanding the process and the related knowledge on design are very important before implementing the system using API provided by 3D CAD system. In this research, an eight-step procedure is proposed for the development of a design automation system. These eight steps are analysis of needs, determination of specification, verification of specification using 3D CAD system, inspection of related API functions, programming, field test, application in practice, and maintenance. A case study in which five design automation systems in the design of turbine generators using the proposed method is introduced in detail. These systems play important roles in the generation of various output items including 3D models, drafts, material information, and NC data. The case study shows how effectively the design time is reduced and the quality improved using those systems.

  • Objectives : Traditional medicine(TM) of East Asia has been taking its status as part of complementary and alternative medicine(CAM) in the UK. However, the efficacy and safety issues make it hard to be accepted in the healthcare system. The aim of the research is to find out the current status of TM of East Asia in the UK and to discuss some issues around its acceptance as formal healthcare method. Methods : Articles, books and regulations related to the acceptance of TM of East Asia were analysed and the internet websites were visited such as Westlaw UK for legal materials, government websites for formal documents, and some UK-based associations. Keyword searches were followed and the essential parts from the articles and documents were generalised for the analysis and discussion. Results : Issues over TM of East Asia include identity as medicine, efficacy and safety, and the statutory regulation can be a measure for the acceptance. Osteopathy and chiropractic therapies came under statutory regulation among the CAM in the UK. Conclusions : TM of East Asia could be under the statutory regulation in the near future. Efficacy and safety issues are the challenging barrier. However, the approach from the viewpoint of TM of East Asia is necessary for development and good practice. The simplified registration procedure for traditional herbal medicinal product in EU can be the model. Education, evaluation, assessment and managing quality of practice are essential for the standard care and formal regulation.

  • In this era of globalization and fierce competition, R&D is an essential part of corporate development strategy. Accordingly, much effort has been devoted to identify and verify best practices for successful R&D and to improve R&D processes. Nevertheless, there is still lack of a comprehensive framework for assessing the quality of R&D process, which can be used as a step-by-step guide for process improvement. Therefore, this study purposes to develop a framework for assessing R&D process based on the concept of CMMI, which is a process improvement approach that defines the essential elements of effective processes. In particular, we suggest three types of R&D process-new product development, new service creation and new technology creation-and then develop a customized framework for them. For this purpose, we firstly investigated the characteristics of R&D activities for each type of process and identify its base practices from an extensive literature review. Then, the CMMI approach was adopted and modified to suit the R&D process. Finally, an illustrative example was provided to demonstrate the assessment process and a prototype web-based assessment system was suggested. Research findings will help understand the characteristics of different types of R&D process and provide a customized guidelines for R&D process assessment and improvement.

  • Companies have been making considerable efforts to develop innovative products for better competitiveness in the market, however, the education curriculum for innovative product development (IPD) in domestic universities needs has not been well developed. The present study was intended to identify the needs of students and practitioners regarding teaching subjects, pedagogical methods, and industry-academia collaboration that can be reflected in the development of IPD education curriculum. Through a literature survey 46 IPD teaching subjects of 7 categories (planning, feasibility analysis, concept development, product design, manufacturing process design, production, and ethics & law) were selected. Opinions on the preferences and importances of the teaching subjects, pedagogical methods, and industry-academia collaboration were collected from 53 college students who took courses of product development and 36 practitioners working in product development. While the students preferred the balanced teaching of all the subject categories, the practitioners suggested planning and concept development be taught with high importance; 6 subjects (product development strategy, customer needs identification, market research, concept generation method, design ideation method, and ergonomic design) received high ratings of preference and importance. The students preferred the mix of various pedagogical methods (lecture, discussion, presentation, practice, and case study) and provided needs on each pedagogical method. Lastly, the students wanted an opportunity of learning through industry-academia collaboration and the practitioners provided ideas for mutual benefits between industry and academia. The needs of students and practitioners identified in the study can be effectively applied to develop a better IPD education curriculum.

  • Researchers have employed a diversity of definitions and measurement methods for creativity. As a result, creativity research is underrepresented in the literature and the findings of different studies often prove difficult to draw into a coherent body of understanding. With regard to assessment, there are some important problems both in creativity research and practice, such as originality bias and Big-C creativity bias in teachers' perceptions about creativity and creative thinking, and additive rather than multiplicative scoring systems of creativity assessment. Drawing upon most widely accepted conceptions of the creativity construct, I defined 'student's scientific creativity' as the ability to make a product both original and useful to the student in terms of little-c creativity, and 'scientist's scientific creativity' as the ability to come up with a product both original and useful to the science community in terms of Big-C creativity. In this study, an 'Assessment Formula for Scientific Creativity' was developed, which is consisted of the multiplication of originality and usefulness scores rather than the sum of the two scores, and then, with scores calculated from the assessment formula, the scientific explanations generated by children were categorized into four types: routine, useful, original, and creative types. The assessment formula was revealed to be both valid and reliable. The implications of the assessment formula for scientific creativity are examined. The new assessment formula may contribute to the comprehensive understanding of scientific creativity to guide future research and the appropriate interpretation of previous studies.

  • Product Line Engineering(PLE) is an effective software development technique which produces applications using core assets. Because of reusing the core assets, PLE can save cost for developing products in a domain but increase reusability. There are about ten PLE methodologies available, but there are not yet common agreements on PLE process and artifacts. This makes developers harder to choose a methodology and to apply it in practice. A comprehensive technical evaluation and comparison on existing PLE methodologies would be essential for practitioners. In this paper, we present a technical assessment of representative PLE methodologies; FAST, SEI SPL, PuLSE, Bosch's PL proceis, FOPLE, ESAPS, KobrA/PoLITe, Alexandria, COPA, QADA. They are compared in the criteria of process, artifacts, instructions, and special features. And we identify common or variable elements between methodologies and confirm elements to be improved in each PLE methodology. The assessment result would be well utilized in defining a practical methodology for PLE projects and in choosing an appropriate methodology among available ones.
