This research is to analyze the status of menu guides provided to inpatients in Korean hospitals, analyze the problem of delivering information, and propose improvement plans through information visualization as a part of improving service for inpatients. The nutrition department in hospitals were directly visited, data were collected, and the types and contents of menu guides were analyzed. Then, problems were found by focusing on whether there is an effective delivery of information, in terms of information visualization aspects. The menu provided to inpatients in Korean hospitals are divided into general, optional, and therapeutic menu depending on patients' conditions, and the menu guide is largely divided into a general guide and optional guide. The information covers menu, origin of ingredients, guide, withdrawal time, etc. However, there is no categorization according to the contents or importance of information, thus creating inefficient problems for patients to acquire information. The problem of menu guides is that they do not deliver information properly due to disorganized information. In order to improve this, information should be categorized and visualized according to its contents and importance for enhancing readability, which will then be able to provide menu guides that can deliver information more efficiently to patients.

Purpose: One of the current services, providing information to the patients and their guardians by using promotion materials induces positive responses and contributes to the improvement of the hospital reliability. Therefore, the objective of this study is to evaluate the effectiveness of audio visual materials, one of the means of promotion, as a way to give accurate medical information to resolve patient's curiosity about purpose and procedure of their examination and deplete complains about waiting which attributes negative effect to service quality assessment. Materials and Methods: 60 patients(mean age $53.97{\pm}12.24$, male : female = 26 : 34) who had $^{18}F-FDG PET/CT$ scan from July 2012 to August 2012 in Seoul Asan Medical Center were referred to the study. All of the patients having PET/CT scan were asked to watch an informative video material before the injection of radiopharmaceutical ($^{18}F-FDG$) and to fill in a questionnaire. Results: As a result of analyzing the contents of questionnaire, 52% of 60 patients had PET/CT scan for the first time and 72.4% of the patients read the PET/CT guidebook offered from their outpatient department or inpatient wards before their scan. After we searched the level of previous knowledge of the purpose and method of PET/CT scan, the patients answered 25.1% "know well", 34% "not sure", 40.9% "don't know" respectively. And 84.7% of the patients answered that watching the PET/CT guide video before the injection helps understanding what exam they were having and 15.3% of the patients did not. For the question asking ever the patients have experienced using our homepage or smart phone QR code to see the guide video before they visit out PET center, only 3.3% of them answered "yes". Lastly, the patients answered 60.1% "yes", 31.4% "so so" and 8.5% "no" respectively for the question asking whether watching the video makes the patients to fill the waiting time short. Conclusion: It is found that understanding of objective and method of the PET/CT scan and level of satisfaction was improved after the patients watched the guide video whether they had PET/CT scan before and read the PET/CT guidebook or not. Also, watching the video was effective for the reduction of perceptible waiting time. But while displaying the PET/CT guide video is useful for providing information about the scan and shortening the waiting time as one of the medical service, utilization of service was actually very poor because of the passive promotion and indifference of the patients about their examination. Therefore, from now on, it is necessary to construct the healthcare system which can be offered to more patients through the active promotion.
