  • Background: The pharmacy education system in South Korea has changed from four-year degree program to two-year pre-pharmacy program plus four-year professional degree program (a total of six years) since 2009. Objectives: The purpose of this study is to assess final year student's satisfaction on this new pharmacy education system and to explore factors related to student satisfaction. Methods: A paper-and-pencil survey instrument was administered to all final year pharmacy students at four universities located in South Korea during September of 2014. The self-administered questionnaire contained 39 items. In part 1, the quality of education with regards to school utilities, education system, human resources, and communication domains were measured. In part 2, overall satisfactions with the new education system were asked to students. Responses were recorded on a seven point Likert scale. Results: A total of 207 students were participated in this study. Students showed low satisfaction on school utilities and standardization of education while they displayed high level of satisfaction on the quality of the faculty members and preceptors at clerkship sites. Factor analysis showed that education service was the most significant factor that affects students' satisfaction followed by facilities, standardized education, communication, administration, pharmacy practice (p<0.05). Conclusion: The qualification of faculty and preceptors ranked number one in students' satisfaction and it was the most significant factor. School facilities were found to be the second most significant factor in students' satisfaction while students displayed poor satisfaction. The study results might need to be reflected in future education planning to improve students' satisfaction.

  • Purpose: The purpose of this study was to analyze effects of a community-based case management program for clients with hypertension living in the community. Methods: The research design was a one group pre and post-test design with 30 participants with hypertension who agreed to participate in the 8-12 week case management program provided by case managers from the National Health Insurance Corporation in 2002. Data were collected three times, before and after the case management services, and 6 months later. Outcomes included changes in blood pressure, knowledge of hypertension and daily life practices, including alcohol consumption, smoking, exercise, and medication adherence. Results: Repeated-measures ANOVA and post-hoc tests of means revealed significant differences before and after service for systolic blood pressure, daily life practices (monitoring body weight and BP, low salt and cholesterol and high vegetable diet, and stress-relief practices), and exercise. The goal for medication adherence was attained after service. Significant improvements from baseline to 6 months after service were observed in measures of salt and vegetables in diet. There were no significant differences on hypertension knowledge, alcohol consumption or smoking behavior between before service and after, and at 6 months. Conclusion: The findings provide preliminary evidence that case management intervention can have positive outcomes on BP control, daily life practices, exercise, and medication adherence for clients with hypertension. However, additional interventions are needed to sustain long-term effects.

  • Introduction: Mobile learning enables users to interact with educational resources while in variable locations. Medical students in residency positions need to assimilate considerable knowledge besides their practical training and we therefore aimed to evaluate the impact of using short message service via cell phone as a learning tool in residents of Obstetrics and Gynecology in our hospital. Methods: We sent short messages including data about breast cancer to the cell phones of 25 residents of gynecology and obstetrics and asked them to study a well-designed booklet containing another set of information about the disease in the same period. The rate of learning derived from the two methods was compared by pre- and post-tests and self-satisfaction assessed by a relevant questionnaire at the end of the program. Results: The mobile learning method had a significantly better effect on learning and created more interest in the subject. Conclusion: Learning via receiving SMS can be an effective and appealing method of knowledge acquisition in higher levels of education.

  • This study was carried out response surface analysis for brown sauce optimization. Three factors of heating time (10, 20, 30, 40, and 50 min), the added gelatin content (0, 4, 8, 12, and 16%) and the added tomato paste amount (0, 6, 12, 18, and 24%) were encoded into 5 levels (-2, -1, 0, 1, 2). After the central synthesis plan was set up to produce samples in 16 pre-arranged conditions and the sensory tests were conducted, the investigation on optimum level of these factors was conducted. The scope of optimum conditions for extraction was established through reading the range of reaction surfaces superimposed between those representing sensory properties such as color, flavor, taste, viscosity and overall acceptability was established. In this study, it was found out that the scope of optimum conditions for brown sauce extraction was 30 min for heating time, 9.00% for gelatin content and 11.25% for tomato paste amount. The reliability test proved the mentioned scope to have a similar value to that of the estimated scope when compared to the experimental values which was observed through experiments conducted under the same conditions as applied to values predicted through RSM program, enabling the verification of the reliability of derived regression formula.

  • The purpose of this study was to evaluate whether screening by clinical breast examination (CBE) in addition to mammography affected participant satisfaction in the National Cancer Screening Program (NCSP). Data were derived from the Quality Evaluation of National Cancer Screening satisfaction survey. This population-based nationwide telephone survey included participants who had been screened by the NCSP for breast cancer between June and August 2010 (n=2,370), and collected information on satisfaction with screening and screening service use. Five multiple regression models were used to determine satisfaction according to screening method, and according to each of five satisfaction measures (pre-screening information transfer, staff interpersonal skills, physical surroundings, reporting of results and general satisfaction). A total of 1,858 (78.4%) participants were screened by mammography alone and 512 (21.6%) by both mammography and CBE. Satisfaction was significantly higher in subjects screened by both mammography and CBE compared with those screened by mammography alone.

  • In general, the braking system of a high speed train has an important role for the safety of the train. To stop safely the train at its pre-decided position, it is necessary to properly combine the various brakes. The train has adopted a combined electrical and mechanical (friction) braking systems. In order to design a good brake system, it is essential for designers to predict the brake performance. In this paper, the braking performance analysis program has been developed and verified by comparing the simulation results with the brake test results of HSR-350x; both results match very well. Also, the brake performances of high speed trains can be predicted by using this program under various conditions.

  • Constructivism is defined in a variety of ways (e.g., constructivist research paradigm, sociological constructivism, and philosophical constructivism) and applied in vastly different contexts. Among the various usages and interpretations of constructivism, one is educational constructivism that embodies an epistemological view of knowledge and learning that is an alternative to naive empiricism or classical behaviorism. To represent the full range of stances taken by educational constructivists, three versions of educational constructivism were considered in this study: individual constructivism originating in the work of Piaget, the radical version of constructivism associated with von Glasersfeld, and the social constructivism of Vygotsky. I investigated preservice teachers' meaning construction about constructivist epistemology as they went through their preservice teacher education program using in-depth interviews. This preservice teacher education program employs constructivist aspects of teacher education and generates applications of constructivism to the practice of teaching. Features of preservice teachers' internalized meanings of educational constructivism include: (1)traditional pedagogy as the default, (2) Literal interpretation of constructivism, (3) Individual constructivism as conceptual change learning, (4) Radical constructivism as a strong individualistic philosophy, (5) Social constructivism as being too ideal to be practical. A compilation of the teachers' own statements about how to implement conceptual change learning and their projected role as constructivist teacher is also provided.
