This study was designed to implement Activity-Orientated Career Education for college students, using the web-based interface. A draft web interface was designed by Rapid Prototyping and was thereafter taken to experts to review and determine the designs, in order to achieve the purpose of the study. Firstly, the sequence of activities of career education was run in accordance with the systematic order of Action Learning, in order to understand the overall design direction. Secondly, the design of the study may result in virtuous cycle-to-cycle. According to two major design directions, on the learning environment platform, the interface consisted of, knowing who I am; knowing who others think I am, knowing the job world; career decisions; career action plans; action planning; individual and co-evaluation; reflection; etc. These steps were designed to be implemented in accordance with strong interactivity of Wiki and Web 2.0 designs. This study was able to implement career education experiences centered around the activities of students at university, as well as experts, in order to increase the accessibility of Career Based Education on the web.

This is an implementation study towards the development of a strategy to improve the pneumonia adequacy evaluation index of regional public hospital and to confirm its effectiveness. One physician, eight nurses, one computer room staff, and one nursing professor working at a regional base public hospital located in N city participated in this study from March to October 2021. An implementation study was conducted based on the conceptual model of Zuber-Skerritt & Fletcher. The stages of planning, implementation, evaluation, and reflection were operated in two cycles, and the effectiveness was evaluated in the second and third quarters. Compared to the pneumonia adequacy evaluation index in 2019, all indicators reached 100% of the standard target in 2021. The results of this study therefore infer that to provide higher quality medical services in the future, it is necessary to apply medical quality improvement activities through practical research under multidisciplinary participation and cooperation and to review the applicability of clinical sites.

Purpose: This study was conducted to evaluate the effectiveness of an evidence-based nursing (EBN) course using action learning-based team learning in undergraduate nursing students. Methods: A quasi-experimental pretest-posttest control group design was employed. The participants who consented were 45 second-year nursing students (22 in the experimental, 23 in the control group) from a university in G-city, Korea. The intervention included lectures, practicals, team activities and reflection on overviewing EBN, formulating clinical questions, searching the evidence, and criticizing the research articles. At the beginning and the end of the 7-week EBN course, the participants completed self-reported questionnaires. Frequencies, $x^2$-test, t-test, and ANCOVA with the SPSS program 18.0, were used to analyze the data. Results: The experimental group showed significantly higher scores on EBN competency (F=25.80, p<001), information literacy (F=13.75, p=.001), and proactivity in problem solving (F=5.32, p=.026) than the control group. Conclusion: This study provides evidence that an EBN course improves undergraduate nursing students' EBN competencies, information literacy, and proactivity in problem solving. Team learning in EBN education can be an effective teaching strategy.

This study investigated the relation between social worker's reflective thinking levels and the usage of social work practice skills. Dewey definded reflective thinking as active, persistent and careful consideration of any belief. And social work practice skills refer to those purposeful intervention activities, that are intended to alleviate client's distress, enhancing a client's coping abilities. Reflctive thinking levels consists of intensive reflection, reflection, understanding and habit action. The key of social work practice skills can be categorized into three major categories: supportive skills, therapeutic coping skills and case management skills. These categories were designed to apply to a diverse range of client populations. This paper proves that social work's reflective thinking ability and interactions with other workers have an effect on the intervention activities. In conclusion, this research indicates that if social works have a higher reflective thinking levels, they will creat practice siklls and social work practice knowledge.

This study aims to explore characteristics of pedagogical reasoning and action of beginning science teachers that naturally and spontaneously occurs in a professional learning community. Three novice middle school science teachers who majored chemistry education in A college of education, passed the examination for selecting secondary school chemistry teachers, and had a common goal of designing 8^th grade science lesson plan voluntarily created a professional learning community and had weekly meetings over a year. Main data sources included transcribed audio-recording of 11 meetings of three science teachers in a professional learning community. Data was analyzed using Shulman's pedagogical reasoning model that includes comprehension, transformation, instruction, evaluation, reflection, and new comprehension to identify characteristics and features of pedagogical reasoning in a professional learning community. Data analysis revealed that pedagogical reasoning in a professional learning community comprises not only preparation, representations, instructional selections, and adaptation but also evaluation, reflection, and new comprehension in transformation stage. Reflection in transformation stage leads teachers to be actively engaged in discussion and get new comprehension on each sub-component(preparation, representations, instructional selections, adaptation, and evaluation) of transformation stage.

Present study examined the functionality of the solitary wave (tsunami) control of the two-rowed porous submerged breakwater by numerical experiments, using a numerical wave tank which is based on the Navier-Stokes equation to explain fluid fields and uses a Volume of Fluid (VOF) method to capture the free water surface. Solitary wave was generated by the internal wave source installed within the computational zone in the numerical wave tank and its wave transformations by structure were compared with those in the previous study. Comparisons with the precious numerical results showed a good agreement. Based on these results, several tow-dimensional numerical modeling investigations of the water fields, including wave transformations, reflection, transmission and energy flux, by the one- and two-rowed permeable submerged breakwater under solitary waves were performed. Even if, it is a research of the limited scope, in case of two-rowed permeable submerged breakwater with $h_0/h=0.925$ ($h_0$ is height of submerged breakwater and h is water depth), the wave height damping in range of $l/L_{eff}>0.4$($L_{eff}$ is effective distance of solitary wave) can reach nearly 60% of the incident wave height. In addition, it is found that reflection coefficient increases nearly 47% and transmission coefficient decreases nearly 18% than one-rowed one. The numerical results revealed that the tow-rowed submerged breakwater can control the incident solitary wave economically and more efficiently than the one-rowed one.

Macrolide antimicrobial agents including erythromycin, roxithromycin, clarithromycin, and azithromycin are commonly used in the treatment of respiratory tract infections in children. Newer macrolides that have structural modifications of older drug erythromycin show improved change in the spectrum of activity, dosing, and administration. However, recent studies reported that increasing use of macrolide antibiotics is the main force driving the development of macrolide resistance in streptococci. In particular, azithromycin use is more likely to select for macrolide resistance with Streptococcus pneumoniae than is clarithromycin use, a possible reflection of its much longer half life. Recently, erythromycin resistance rates of S. pneumoniae and Streptococcus pyogenes are rapidly increasing in Korea. Two main mechanisms of acquired macrolide resistance have been described, altered binding site on the bacterial ribosome encoded by the ermB gene and active macrolide efflux pump encoded by the mef gene. Relationship between the susceptibility of S. pneumoniae and the response to macrolides has been shown in studies of acute otitis media, but less clear in cases of pneumonia. This article reviews the spectrum of activity, pharmacokinetic properties, mechanisms of action and resistance, and clinical implication of resistance on the treatment of respiratory tract infections in children.

The aims of this study were three-fold; to analyze the trends of research on children's media, to anticipate any transitions in the direction of the research and finally to provide a guidance for future directions in the research. For this purpose, 55 research papers were chosen. The tool used for this analysis was that developed by Meyrowitz(1998; 1999), which classifies(1998, 1999) three main viewpoints towards media. Based on these three viewpoints, this study found that the most common category is 'media as a vessel.' Furthermore, it was verified that some studies in 'media as a vessel' have a tendency to be mixed with the notion of 'media as a language.' Subsequently, all the research papers in the category of 'media as a language' were subcategorized into 6 digital literacy competencies, in the manner proposed by Hobbs(2010). Consequently, the studies in the category of 'creation' were revealed to be the most common, and it was further confirmed that the research included in the categories of 'reflection' and 'social action' both begins to partially appear. Based on these results, this study speculates on a number of educational points supporting the development of media education in the digital era.

Since major reason of disaster in coastal area is wave action, prediction of wave deformation is one of the most important problems to ocean engineers. Wave deformations are due to physical factors such as shoaling effect, reflection, diffraction, refraction, scattering and radiation etc. Recently, numerical models are widely utilized to calculate wave deformation. In this study, the mild slope equation was used in calculatin gwave deformation which considers diffraction and refraction. In order to slove the governing equation, finite element method is introduced. Even though this method has some difficulties, it is proved to predict the wave deformation accurately even in complicated boundary conditions. To verify the validity of the numerical calculation, experiments were carried out in a model harbour of rectangular shape which has mild slope bottom. The results by F.E.M. are compared with those of both Lee's method and the experiment. The results of these three methods show reasonable agreement.

Purpose: The purpose of the study was to identify and describe illness experiences of men with myocardial infarction. Methods: Data were collected through individual in-depth interviews with 10 male patients. Analysis was done using phenomenological analysis. Results: Five theme clusters including 11 themes emerged. 1) "Unexpected grave disease instantly dividing life and death" describes the great ignorance of symptoms and experience as a survivor narrowly escaping death. 2) "A disease still not considered a disease" illustrates the paradoxical and confusing situation between low level of awareness of the severity of the disease and high level of reflection on their unhealthy lifestyles. 3) "Fighting against me for health" illustrates their resolution and action to maintain health while experiencing helplessness. 4) "Relationships in a no-win situation" contains defensive posture due to social stigma and the dilemma of family breadwinners. And 5) "Introspection of past and future life" describes positive turnings in life through enlightenment in addition to remorseful feeling about the past and persistent worry of death. Conclusion: Health professionals need to support men with myocardial infarction by providing family-oriented and empowerment-based self-management interventions to lead to success in their illness journey and to improve their quality of life.
