In this study, we investigated that consumers could differentiate between levels of claims and clarify how a visual aid influences consumer understanding of the different claim levels. We interviewed 2,000 consumers in 13 shopping malls on their perception of and confidence in different levels of health claims using seven point scales. The average confidence scores given by participants were 4.17 for the probable level and 4.07 for the possible level; the score for the probable level was significantly higher than that for the possible level (P < 0.05). Scores for confidence in claims after reading labels with and without a visual aid were 5.27 and 4.43, respectively; the score for labeling with a visual aid was significantly higher than for labeling without a visual aid (P < 0.01). Our results provide compelling evidence that providing health claims with qualifying language differentiating levels of scientific evidence can help consumers understand the strength of scientific evidence behind those claims. Moreover, when a visual aid was included, consumers perceived the scientific levels more clearly and had greater confidence in their meanings than when a visual aid was not included. Although this result suggests that consumers react differently to different claim levels, it is not yet clear whether consumers understand the variations in the degree of scientific support.

PURPOSE: Patients and their caretakers need to understand various problems and requirements in the dying process so that they may prepare for death for the rest of their remaining life. Accordingly, a systematic audio-visual resource was developed to educate hospice patients and their families at the palliative care ward about the process of dying. METHODS: For the development of an audio-visual resource, a initial education material was produced in the form of simple and accessible Power Point handouts based on literature study. Then, the program was completed through five rounds of a process, including expert advice, revision, update and evaluation. RESULTS: The final version of the program was filmed with cooperation of the medical literature information division. Using the program, patients and families were educated through five phases over three sessions for a total 26 minutes and 34 seconds. CONCLUSION: The significance of this study lies in the fact that it was conducted after the establishment of the palliative care ward, which made it easier for nurses provide the education. It is expected that the program may be used by hospice specialists as well as nurses as an education resource for hospice patients and their families.

During endoscopy, most endoscopists insert endoscopes into the esophagus without visual aid in order to minimize the discomfort to patients. However, studies have shown that visual guided insertion imposes little discomfort, is safe and can increase the diagnostic rate of abnormal pathology of the throat. As for the treatment of hypopharyngeal lesions, cases of endoscopic treatment are rare and any guidelines have not been clearly defined yet. However, endoscopic treatment may be feasible in selected cases. Several procedures, such as endoscopic mucosal resection with cap (EMR-C) and saline injection polypectomy can be applied. We experienced seven patients who had benign hypopharyngeal masses that were removed endoscopically without serious complications. Compared to surgical treatment, endoscopic removal of the benign hypopharyngeal tumors does not require general anesthesia; it is simple, less invasive and less costly. Therefore, endoscopy should be regarded as a treatment option. However, further studies are required before widespread application of endoscopic removal for the definitive treatment of hypopharyngeal masses, including malignancies.

We have reported general principles of low vision aid prescription. But, we have not reported near vision aid prescription only. So, we analyse prescriptions of near low vision aid(diagnosis, type, magnification, etc) and present new near low vision aids that patients feels comfortable. We reviewed the clinical records of 100 patients who visited our low vision clinic more than twice and was prescribed near low vision aid for low vision. According to the data analysed, optic nerve atrophy was the most common etiology for low vision. Illuminated hand held magnifier(31.3%), telemicroscope with plus cap(27.7%), aspheric doublet sens(Clear Image II)(24.1%) were low vision aids most commonly used for near vision, but we knew new trend that newly prescribed aids(telemicroscope with plus cap, aspheric doublet lens) were prescribed more than illuminated hand held magnifier. After prescription of the low vision aid, visual acuity improved significantly (p<0.05). We examined contrast sensitivity test to measure the functional acuity and predict the visual prognosis after prescription of low visio aid.In addition,we studied the relationship between reading speed and the degree of contrast sensitivity and we knew that the relationship between degree of contrast sensitivity and reading speed was associated(p<0.05). Majority of patients(89%) were benefited from prescribed low vision aids.

OBJECTIVES: Few disciplines in medicine encompasses such wide diagnostic and treatment modalities as cardiology. A traditional text and education system is limited in its efficacy to convey such variety. In order to address this problem, a comprehensive computer-aided education system that compiles and links the current knowledge of cardiovascular diseases is proposed. An availability of such system through CD-ROM and world wide web will contribute undoubtedly to the promotion and betterment of current understandings of cardiology all over the world. METHODS AND RESULTS:1) The information about the cardiovascular diseases has been complied and organized. Multimedia medical information includes text, audio features that allow the users to study actual sounds, and visual aids (slides, real-time demonstration, and schematic illustrations).2) Cardiology education system can be approached according to "Disease module" or "Laboratory test module". One can readily look up the disease of interest and see the results of different tests. Or one can choose the laboratory test or physical examination and study the differences among the diseases. "Self test module" is also available to help user's self assessment of his/her understanding of cardiovascular diseases.3) This cardiology education program is conveniently stored in CD-ROM and can also be accessible through the world wide web (http://med.chungbuk.ac.kr/~mccho/ web-cardiology/alogo.html). CONCLUSION: A multimedia approach for the study of cardiovascular diseases has been developed and is now avaliable in CD-ROM. The same information can be obtained from our home page through the world wide web.

Medical doctors are an important role model for smoking behavior, and their advice to quit smoking is effective for patients. Doctors can be teachers and educators for social anti-smoking activities in their communities. Schools, social organizations, hospitals, and local and national government officials can be interested in providing anti-smoking programs. Well-preparedness is important for an effective delivery of anti-smoking messages. To ensure the success of presentation, the organizers should consider the followings: (1) determine the objectives before planning the presentation; (2) analyze the values and needs of the audience; (3) determine the best presentation method; (4) make the presentation interactive through questions and answers or activities (5) select slides and other visual aids carefully; (6) incorporate introduction and conclusion to the main ideas; and (7) prepare answers to anticipated questions. Colors and layouts should be considered in preparing and showing visual aids. For those deliver presentation, repeated rehearsals will make them more relaxed and at ease, which is also important for successful presentation. Each presentation will be different because the needs and receptivity of the audience will be different in each occasion. Give the audience a clear idea of what your goals of the presentation are. Let them know first what materials including handouts will be distributed, lest they should distract their attention taking unnecessary notes. Establish a firm rapport and give information. Remember that there may be smokers; don't insult or degrade them. Acknowledge the challenges in smoking cessation and make a caring, non-hostile tone towards smokers.
