River state classification combining patch-based processing and CNN.

This paper proposes a method for classifying the river state (a flood risk exists or not) from river surveillance camera images by combining patch-based processing and a convolutional neural network (CNN). Although CNN needs much training data, the number of river surveillance camera images is limited because flood does not frequently occur. Also, river surveillance camera images include objects that are irrelevant to the flood risk. Therefore, the direct use of CNN may not work well for the river state classification. To overcome this limitation, this paper develops patch-based processing for adjusting CNN to the river state classification. By increasing training data via the patch segmentation of an image and selecting patches that are relevant to the river state, the adjustment of general CNNs to the river state classification becomes feasible. The proposed patch-based processing and CNN are developed independently. This yields the practical merits that any CNN can be used according to each user's purposes, and the maintenance and improvement of each component of the whole system can be easily performed. In the experiment, river state classification is defined as the following problems using two datasets, to verify the effectiveness of the proposed method. First, river images from the public dataset called Places are classified to images with Muddy labels and images with Clear labels. Second, images from the river surveillance camera in Nagaoka City, Japan are classified to images captured when the government announced heavy rain or flood warning and the other images

One-day psychosocial education program for people with epilepsy: A continuation study of the “Epi-school”

Psychosocial education programs for people with epilepsy (PWE) can improve epilepsy knowledge and quality of life (QOL), whereas the availability of these programs is limited in Japan compared to other developed countries. This study evaluated the feasibility and effectiveness of a one-day group psychosocial education program named the “one-day Epi-school” for PWE and their relatives. The previous program (Epi-school) required consistent participation in three sessions, resulting in problems with program continuation rates, with 45.5% of PWE completing the program. Therefore, the “one-day Epi-school” was designed to provide information about epilepsy and address psychosocial issues related to coexisting epilepsy symptoms, such as self-stigma and self-esteem, while allowing participants to accomplish these programs within a single day. The study recruited a sample of 32 PWE and their relatives from a psychiatric clinic. They completed assessments of knowledge, self-stigma, self-esteem, and quality of life before and after the program. The results exhibited a significant increase in epilepsy knowledge after the intervention for PWE and their relatives. However, we could not identify other significant changes. The participation completion rate was 100%. The post-participation questionnaire proved beneficial to interact with other PWE. The study suggests that a single intervention, e.g., the one-day Epi-school, may be insufficient for enhancing other factors, yet it can be an adequate opportunity for learning and interacting. It is also necessary to implement future studies with larger sample sizes, a control group, and prolonged follow-up periods for the program's value and validity

Internet survey on knowledge and perceptions of epilepsy among the general public in Japan

Objective: To improve the life quality of people with epilepsy, it is necessary to provide comprehensive epilepsy care and disseminate accurate information related to epilepsy to the public. In Japan, reports of traffic accidents involving people with epilepsy started to draw attention in the media in 2011. Ever since that, the association between the image of epilepsy from the general public, “Epilepsy,” and “Danger,” was more robust in 2013. Since 2017, no previous surveys have examined the perceptions and knowledge of epilepsy among the public in Japan. As an essential source of information for epilepsy care, we conducted a nationwide Internet-based survey to elucidate the current state of knowledge and perceptions of epilepsy among the public without epilepsy in Japan. Methods: We conducted an online survey from July 29 to August 2, 2021, with 213 respondents (115 male, 97 female, and one unidentified; mean age: 50.52 ± 12.34 years) registered with an online survey service in Japan. In this survey, we first questioned whether or not a respondent had epilepsy, and then those with epilepsy were excluded from participation. We collected basic demographic information, administered the Epilepsy Knowledge Scale (18 items), and asked the open-ended response question, “What kind of disease do you think epilepsy is? If you do not know, please describe epilepsy in your words.” We adopted quantitative text analysis using KH Coder3 and co-occurrence network analysis to examine the connections between words. Results: Among the respondents, 92% have heard of epilepsy, and 26.8% have observed an epileptic seizure before the survey. The knowledge scale yields an average score of 27.96 ± 21.3 (out of 100), with the question with the highest percentage of correct responses being “People with epilepsy are just as capable as other people” at 51.64%. The question with the lowest percentage of correct responses was “If the person with epilepsy only has seizures during sleep, the person can have a driver's license,” at 9.85%. The average number of Japanese characters responding to open-ended text questions was 10.45 ± 8.87 characters (including Kanji, Hiragana, and Katakana). We found that the word ''froth'' appeared more frequently with experience of observing a seizure, and the words “occur” and “brain” appeared more frequently with higher knowledge of epilepsy. Furthermore, comparing the sources of information from what they learned about epilepsy, the words “seizure,” “faint,” and “consciousness” appeared more frequently in school, with family and friends, and in newspapers and television, respectively. Conclusion: We identified the level of knowledge and perceptions of epilepsy among the general public in Japan in 2021. By analyzing the qualitative aspects of open-ended text responses, we gathered information that might be useful for informing the public of future efforts to provide accurate information related to epilepsy
