Development of a program to prevent sexual violence among teens in Japan: education using DVD video teaching materials and web-based learning

BACKGROUND@#This study aimed to develop an education system using DVD video-based teaching materials or web-based learning to reduce sexual violence among teens in Japan.@*METHODS@#During the first stage, June 2018 to March 2019, an education program using DVD video teaching materials was carried out at three high schools and four universities with research consent from the director of the facility. From 1337 high school students and first- and second-year university students, subjects in their teen years were targeted for analysis. A survey was conducted at baseline and after the DVD video teaching. During the second stage, November 2019 to March 2020, web-based learning using improved video teaching materials was developed and carried out. From the adolescents who participated in the web-based learning, subjects in their teen years were targeted for analysis. A survey was conducted at baseline and after the web-based learning.@*RESULTS@#In the first stage, 876 students consented to and participated in the education using DVD video teaching materials and baseline and after surveys (collection rate 65.5%). Among these, the number of respondents in their teens both baseline and after education was 705 persons (valid response rate 80.4%). In the second stage, the number of respondents in their teens both baseline and after education was 250 respondents in their teens who received web-based learning using the improved video teaching materials (valid response rate 87.1%). The improvement effect of the two programs was observed in attitudes that lead to physical violence, attitudes that lead to mental violence, attitudes that promote healthy conflict resolution, and dangerous attitudes that lead to sexual violence from persons in the community or through the Internet. The web-based learning program achieved an improvement of preventive attitudes toward sexual violence.@*CONCLUSIONS@#The education program using DVD video teaching materials or web-based learning may help prevent sexual violence among teens in Japan.

Training in Endoscopy: Endoscopic Ultrasound

Endoscopic ultrasound (EUS) has been recently established as an indispensable modality for the diagnosis and management of pancreatobiliary and gastrointestinal (GI) disorders. EUS proficiency requires both cognitive and technical abilities, including an understanding of the appropriate indications, the performance of appropriate evaluations before and after the procedure, and the management of procedure-related complications. An increasing demand for skills to handle a growing range of interventional EUS procedures and a continual shortage of EUS training programs are two major obstacles for EUS training. Acquiring the skills necessary to comprehend and conduct EUS often requires training beyond the scope of a standard GI fellowship program. In addition to traditional formal EUS training and preceptorships, regular short-term intensive EUS training programs that provide training at various levels may help EUS practitioners improve and maintain EUS-related knowledges and skills. Theoretical knowledge can be acquired from lectures, textbooks, atlases, slides, videotapes, digital video discs, interactive compact discs, and websites. Informal EUS training is generally based on 1- or 2-day intensive seminars, including didactic lectures, skills demonstrated by expert practitioners through live video-streaming of procedures, and hands-on learning using animal or phantom models.

Comparison of Speech Audiometry Using KS Word List and Hahm's List in Hearing Impaired Adults / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The purpose of this study was to compare speech audiometry test results of the conventional Hahm's list with those of Korean standard word lists for adults (KS-WL-A) using both live voice and compact disc (CD) speech presentation modes. SUBJECTS AND METHOD: Eighty patients with sensorineural hearing loss and 23 control subjects with normal hearing participated in the study. Each hearing loss group comprised 20 subjects (mild, moderate, moderately severe, and severe hearing loss groups). Speech audiometry was performed to measure the speech recognition threshold (SRT) and word recognition score. KS-WL-A was presented either through a live voice mode or recorded CD materials. Test words from Hahm's list were presented using the live voice mode only. Pure tone audiometry was also conducted for all subjects. RESULTS: Differences between the SRT and pure tone average were within 6 dB in all subgroups in all three stimulation methods, indicating high reliability of the SRT in both the conventional and Korean standard methods. The moderate, moderately severe, and severe hearing loss groups showed lower word recognition scores in the CD mode with KS-WL-A than with the two live voice modes. CONCLUSION: Both the live voice mode and CD mode showed reliable speech audiometry test results in normal and hearing-impaired subjects. Although the CD mode is recommended to standardize test methods and reduce test errors, the live voice mode might be more effective for patients with moderate to severe hearing loss.

Development of Compact Disks in Speech Audiometry and First Stage Verification for the New Speech Materials / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: To standard test method of Korean speech audiometry, we developed an audio compact disk, the KsoM-07 (Korean Society of Otolaryngolgy, Monosyllabic, 2007) word lists and evaluated them for clinical usage. SUBJECTS AND METHOD: The monitored live voice (MLV) of a female talker was digitally recorded with a Beltone audiometer and the GoldWave program. The calibration for each word was done by calculating the root-mean-square (RMS) at the moving time of 300 ms using MATLAB(R) (7.0 version, The MathWorks, Inc. Natick, Massachusetts, USA) and the GoldWave (v 5.25 GoldWave Inc. St. John's, NL, Canada) program. The discrimination score was measured in 20 normal subjects to obtain psychometric function curve of each word and to compare the homogeneity of two lists. The first verification methods for new speech materials were done by comparing the discrimination scores of the flat type and the descending types at 150 sensorineural hearing loss with similar pure tone threshold. RESULTS: 44% of MLV recording was above +/-3 dB deviation and had to be recalibrated. Two lists showed equal difficulty or homogeneity in normal subjects. Discrimination scores were statistically different among the groups with respect to hearing level and the slope of audiogram. CONCLUSION: KsoM-07 word lists were relatively homogeneous and showed differences between the descending type and the flat type of hearing loss. Therefore, KsoM-07 word lists can be useful in evaluating the impairment found in the descending type of sensorineural hearing loss as well as in serving as a new speech test material for Korean monosyllabic words.

Demonstration of nasogastric intubation using video compact disc as an adjunct to the teaching processes.

BACKGROUND: An in-house produced video compact disc (VCD) demonstrating nasogastric intubation was introduced to the medical curriculum at Buddhachinaraj Hospital, Clinical Teaching Centre, Phitsanulok in 2005. OBJECTIVE: The present study aimed to qualitatively evaluate the effect of the VCD on our medical students' procedural skills. MATERIAL AND METHOD: The 6th year medical students were randomly allocated into two groups; one group viewed the VCD (test, n = 30), and the other group did not (control, n = 31). After 2 months, the authors examined all students by asking them to perform the procedure using a manikin and a checklist. The examiners were blind to the allocations at the time of examination. Unpaired t-tests and Chi-square tests were used Data are expressed as mean and SD. RESULTS: Total checklist's score was 20. There was no diference in terms of age or gender between the two groups. Thirty of 61 medical students who had watched the VCD got an average score of 15.9 +/-1.86, while the control group's average score was 13.2+/-1.94. Statistical analyses showed that the difference was significant (p < 0.0001). CONCLUSION: The medical students were able to self-improve their procedural skills of nasogastric intubation after viewing the VCD. Application of this method to other basic procedures may be useful.

Effect of Education by Visual Compact Disc on Two time- period of Pre-operation Anxiety of Patients who were Candidates for Coronary Artery Bypass Graft [CABG]

Today, arthrosclerosis of coronary arteries is one of the most common life threatening diseases in patients. In fact, Coronary Artery Bypass [CABG] is high risk surgery in both developed and developing countries and heart is a vital organ that is susceptible for any disorders which could be life theatening, because of undergoing CABG patients with high anxiety and stress. Due to surgery anxiety, heart rate, cardiac output and oxygen demand will rise. Then any attempt to decrease patients' preoperational anxiety would be beneficial. One of the efforts to decrease the anxiety level is patient education. There are different viewpoints about educational methods in the literature. This study was a randomized clinical trial with the purpose of determination of the effect of education with visual compact disc [VCD] on the patients' anxiety at the first day and sixth day of admission. Sixty patients were included, 30 were assigned into experimental group and 30 subjects into control group. Sampling method was consecutive. The Spielbergers' questionnaire was used for data collection pre and post educational intervention. The result indicated that the late trait anxiety level significantly decreased in the experimental group compared to the control group at the 6th day before CABG [t=3.79, P=0.001] [t=4.53, P=0.00] respectively. According to the study results, use of visual information by VCD at sixth day before surgery was more effective in clinical setting that the first day. Therefore, nurses can use this educational cost-effective beneficial intervention, for reducing the patients' anxiety

Influence of threshold value of computed tomography on the accuracy of 3-dimensional medical model / 대한구강악안면방사선학회지

PURPOSE: To evaluate the influence of threshold value of computed tomography on the accuracy of rapid prototyping (RP) medical model MATERIAL AND METHODS: CT datas of a human dry skull were transferred from CT scanner via compact disk to a personal computer (PC). 3-dimensional image reconstruction on PC by V-works(TM) 3.0 (CyberMed. Inc.) software and RP models fabrication were followed. 2-RP models were produced by threshold value of 500 and 800 selected in surface rendering process. Linear measurements between arbitrary 12 anatomical landmarks on dry skull, 3-D image model, and 2-RP models were done and compared. Thus, the accuracy of 500 RP and 800RP models was respectively evaluated. RESULTS: There was mean difference (% difference) in absolute value of 2.27 mm (2.73%) between linear measurements of dry skull and 500 RP model. There was mean difference (% difference) in absolute value of 1.94 mm(2.52%) between linear measurements of dry skull and 800 RP model. CONCLUSION: Slight difference of threshold value in rendering process of 3-D modelling made a influence on the accuracy of RP medical model.

Software for Management of Congenital Vascular Malformation(CVM): A proposal

There is not a unique registry program about the CVM patients in Korea, even in the World. During the business meeting of International Society for the Study of Vascular Anomalies (ISSVA) 1996 in Rome, a sincere discussion took place about the 1988 Hamburg classification of CVM. This was followed by introduction of registry form that could be used universally throughout the world. We developed a CVM registry program calling CVM for world-wide sharing and analysis. This program is a typical database program application system based on Borland's Delphi 1.0 and the database is managed with dBase III+ . It became clear incoporating the Hamburg classification would be natural while expanding the diagnosis and treatment sections. This is a user-friendly, self-explanatory program that hardly needs any tutorial or instruction. Nonthless, for the foolhardy, it comes with manual that explains every aspect of it. Every panel comes with friendly buttons at your service at the stroke of the mouse or the pad. It can be used either on Windows 3.1 or 95, switching back and forth depending on your computer's capability. The program may obtained by diskettes, compact disc or downloaded from the Internet hompage. We will endeavor to upgrade periodcally as necessity arises.
