This paper emphasizes that information received in disaster situations can lead to disparities in the effectiveness of communication, potentially causing damage. As a result, there is a growing demand for disaster and safety information among citizens. A user-centered disaster and safety information application service is designed to address the rapid dissemination of disaster and safety-related information, bridge information gaps, and alleviate anxiety. Through the Open API (Open Application Programming Interface), we can obtain clear information about the weather, air quality, and guidelines for disaster-related actions. Using chatbots, we can provide users with information and support decision-making based on their queries and choices, utilizing cloud APIs, public data portal open APIs, and solution knowledge bases. Additionally, through Mashup techniques with the Google Maps API and Twitter API, we can extract various disaster-related information, such as the time and location of disaster occurrences, update this information in the disaster database, and share it with users.

Chatbots have become very popular in our times and are used in several fields. The emergence of chatbots has created a new way of communicating between human and computer interaction. A Chatbot also called a "Chatter Robot," or conversational agent CA is a software application that mimics human conversations in its natural format, which contains textual material and oral communication with artificial intelligence AI techniques. Generally, there are two types of chatbots rule-based and smart machine-based. Over the years, several chatbots designed in many languages for serving various fields such as medicine, entertainment, and education. Unfortunately, in the Arabic chatbots area, little work has been done. In this paper, we developed a beneficial tool (chatBot) in the Arabic language which contributes to educating people about the Prophet's biography providing them with useful information by using Natural Language Processing.

Objective : The purpose of this study was to investigate establishment status of the mandatory courses designated by Ministry of Health & Welfare for qualification of sensory developmental rehabilitation specialist(SDRS), within curriculum of baccalaureate occupational therapy(BOT) programs in Korea Methods : This is a narrative study to investigate and analyze certain courses established in curriculums of all 4-years occupational therapy(OT) programs, which is 32 schools. Results : 1) The shared mandatory subject, 'Understanding Children with Disabilities(UDC)', has been established at 9 schools. For the branch mandatory subjects, 'Neuroscience(NS) or Neuroanatomy' has been established at all 32 schools, 'Sensory Processing Dysfunctions and Intervention(SPDI)' or 'Sensory Integration' has been established at 31 schools, and each of 'Assessment & Evaluation for Children(AEC)' and 'Practicum of Sensory Rehabilitation(PSR)' has been established 7 schools for same. 2) For the mandatory courses, all 32 schools were offering designated- and alternative courses of NS, SPDI, AEC, but there was no change in the number of schools offering the practicum course since there was no case of alterative for it. 3) In terms of general provision score, there were 4 schools for score 7, 4 schools for score 6, 2 schools for score 5, 1 schools for score 4, 2 schools for score 3, and 19 schools for score 2. Conclusion : Establishment of the mandatory courses required to the qualification of SDRS among the BOT programs in nation were investigated. Including alternative courses, all the branch mandatory courses except practicum course are established in all the 32 schools. However, the shared mandatory subject, UDC and the practicum subject were established in only few schools. In the provision level evaluation of BOT programs for the SDRS qualification, it is shown that many schools has been started the provision already but still many schools' curriculum did not reflect the willingness and accuracy well. For the schools planning successful accreditation in near future, it is recommended that they prioritize the establishment of the shared mandatory course and the practicum course since these two subjects are recognized as critical factors for that. In addition, it is also needed of comparative inspections for course title and syllabi based on the guideline provided by Ministry of Health & Welfare.

An autonomous and automatic home mess-cleanup robot is newly developed in this paper. Thus far, vacuum-cleaners have lightened the burden of household chores but the operational labor that vacuum-cleaners entail has been very severe. Recently, a cleaning robot was commercialized to solve but it also was not successful because it still had the problem of mess-cleanup, which pertained to the clean-up of large trash and the arrangement of newspapers, clothes, etc. Hence, we develop a new home mess-cleanup robot (McBot) to completely overcome this problem. The robot needs the capability for agile navigation and a novel manipulation system for mess-cleanup. The autonomous navigational system has to be controlled for the full scanning of the living room and for the precise tracking of the desired path. It must be also be able to recognize the absolute position and orientation of itself and to distinguish the messed object that is to be cleaned up from obstacles that should merely be avoided. The manipulator, which is not needed in a vacuum-cleaning robot, has the functions of distinguishing the large trash that is to be cleaned from the messed objects that are to be arranged. It needs to use its discretion with regard to the form of the messed objects and to properly carry these objects to the destination. In particular, in this paper, we describe our approach for achieving accurate localization using RFID for home mess-cleanup robots. Finally, the effectiveness of the developed McBot is confirmed through live tests of the mess-cleanup task.

With the development of deep learning technology, voice processing-related technology is applied to various areas, such as STT (Speech To Text), TTS (Text To Speech), ChatBOT, and intelligent personal assistant. In particular, the STT is a voice-based, relevant service that changes human languages to text, so it can be applied to various IT related services. Recently, many places, such as general private enterprises and public institutions, are attempting to introduce the relevant technology. On the other hand, in contrast to the general IT solution that can be evaluated quantitatively, the standard and methods of evaluating the accuracy of the STT engine are ambiguous, and they do not consider the characteristics of the Korean language. Therefore, it is difficult to apply the quantitative evaluation standard. This study aims to provide a guide to an evaluation of the STT engine conversion performance based on the characteristics of the Korean language, so that engine manufacturers can perform the STT conversion based on the characteristics of the Korean language, while the market could perform a more accurate evaluation. In the experiment, a 35% more accurate evaluation could be performed compared to the existing methods.

The shoe last which is the framework for the shoemaking is intensively combined with the 3D data and technologies. International shoe companies have already commercialized 3D printing technology in producing the shoe, but domestic shoe companies are still in their early stages. This study used the 3D scanning, 3D modeling and 3D printing of the high-technology to make the shoe last. This 3D producing processes should be helpful in building competitiveness in domestic shoe industry. The 3D foot scanning data of men in 30s(n=200) were collected in SizeKorea(2010). The basic statistics, factor and cluster analysis were performed. They were categorized in 3 groups by 3D foot measurement data, and the standard models were selected in each group. The cross sections in XY, YZ and XZ planes sliced from 3D scan data of the standard model were used in the sketches of the 3D shoe last modeling. The 3D shoe last was modeled by Solidworks CAD and printed by MakerBot Replicator2; a desktop 3D printer. This research showed the potential for utilization of 3D printing technology in the domestic shoe industry. The 3D producing process; 3D scanning, 3D modeling and 3D printing is expected to utilized widely in the fashion industry within the nearest future.

Background: There are limited data in the literature related to concomitant genital or extra-genital organ pathologies in patients with borderline ovarian tumors (BOTs). The aim of this study was to evaluate our experience with 183 patients to draw attention to the accompanying organ pathologies with BOTs. Materials and Methods: One hundred eighty-three patients with BOTs, diagnosed and/or treated in our center between January of 2000 and March of 2013 were evaluated retrospectively. Data related to age, tumor histology, lesion side, disease stage, accompanying incidental ipsilateral and/or contralateral ovarian pathologies, treatment approaches, and follow-up periods were investigated. Incidental gynecologic and non-gynecologic concomitant organ pathologies were also recorded. Results: The mean age at diagnosis was 40.6 years (range: 17-78). Ninety-five patients (51%) were ${\leq}40$ years. A hundred and forty-seven patients (80%) were at stage IA of the disease. The most common type of BOT was serous in histology. Non-invasive tumor implants were diagnosed in 4% and uterine involvement was found 2% among patients who underwent hysterectomies. There were 12 patients with positive peritoneal washings. Only 17 and 84 patients respectively had concomitant ipsilateral and concomitant contralateral incidental ovarian pathologies. The most common type of uterine, appendicular and omental pathologies were chronic cervicitis, lymphoid hyperplasia and chronic inflammatory reaction. Conclusions: According to our findings most of accompanying pathologies for BOT are benign in nature. Nevertheless, there were additional malignant diseases necessitating further therapy. We emphasize the importance of the evaluation of all abdominal organs during surgery.

Given that American English and British English show differences for several vowels and that Korean students have mainly been exposed to American English, this study examined 27 Korean university students' identification of American and British English vowels. The results showed that Korean students' identification accuracy of American English vowels was higher (64.7%) than that of British English (54.7%), thus indicating that Korean students' familiarity with American English affected the students' identification of English vowels. However, vowel variation also affected students' identification of English vowels in that only the American English vowels in the words beat, bat, but, burt, bart, bite were better identified than the corresponding vowels in British English. Among the vowels which exhibit differences between American English and British English, the students' identification accuracy of the American English vowels in burt, bart, bat was significantly higher than that of British English and the error patterns for these vowels were also different. The analysis of vowel error patterns indicated that Korean students had much difficulty with non-rhotic vowels and [a] in bat in British English. Further, the vowels in bot and boat demonstrated a similar [ɑ]-[ɔ]-[ʌ] confusion and also a confusion between rounded vowels in spite of the differences of these vowels between American English and British English. Some pedagogical implications for teaching of English vowels were discussed based on the findings of the present study.
