This study provided personnel and recruitment information related to job offer and job hunting, and proposed a non-face-to-face platform that can facilitate matching of one-time services as well as periodic services. The existing recruitment and job search method for personal assistant of the disabled is a one-way matching method in which a person in charge of the service providing centers assigns an activity assistant belonging to the institution when a consumer requests an personal assistant service, so the choice of job seekers is very weak. The job matching platform of the activity assistant for the disabled can be logged in separately by dividing users and separating them into the interface of the disabled or the disabled family members (job seekers) and activity assistants for the disabled (job seekers). Search for job offer and job seekers that meet their respective conditions, and real-time bidirectional decision-making through the chat function, and when the activity assistance service is completed, recruiters and job seekers can write service reviews and evaluations from their own point of view. The real-time interactive decision-making matching platform will also help minimize blind spots where it is difficult to provide services when short-term or one-time assistance is needed.

Artificial intelligence-based services are expanding into a new industrial revolution. There is artificial intelligence technology applied in real life due to the development of big data and deep learning related technology. And data analysis and intelligent assistant services that integrate information from various fields have also been commercialized. Chatbot with interactive artificial intelligence provide shopping, news or information. Chatbot service, which has begun to be adopted by some public institutions, is now just a first step in the steps. This study summarizes the services and technical analysis of chatbot. and the direction of public administration service chatbot was presented.

In order to overcome the problems of contact palmprint recognition, a non-contact palmprint recognition system is developed on personal computer (PC) platform. Three methods, namely "double-line-single-point" (DLSP), "double-assistant-crosshair" (DAC) and "none-assistant-graphic" (NAG), are implemented for the palmprint localization to solve the severe technical challenges, including the complex background, variant illuminations, uncontrollable locations and gestures of hands. In NAG, hand segmentation and the cropping of region of interest are performed without any assistant graphics. The convex hull contour of hand helps detect the outside contour of little finger as well as the valley bottom between thumb and index finger. The three methods of palmprint localization have good operating efficiency and can meet the performance requirements of real-time system. Furthermore, an attendance system on PC platform is designed and developed based on non-contact palmprint recognition.

본 연구는 개인이 이른바 '유비쿼터스 개인지식관리 시스템'을 갖추고 있을 때 발생하게 될 것으로 예상되는 마케팅 메시지로서의 지식의 역할에 대한 개념적 연구를 수행한다. 기존의 마케팅 광고 메시지는 인간의 생물학적인 감각과 인지, 기억 능력에 의존하였기 때문에 반복적이고 자극적이어야만 했다. 그러나 유비쿼터스 환경에서는 UPA(Ubiquitous Personal Assistant)를 활용하여 개인이 소비하는 컨텐트를 이음매 없이(Seamless) 습득, 저장할 수 있게 되며, 이러한 변화는 마케팅과 광고의 방법에도 변화를 가져오게 될 것으로 판단된다. 이에 본 연구에서는 유비쿼터스 환경에서의 개인지식관리를 통하여 변화되는 마케팅과 광고의 모습을 나타내고자 하며, 이를 위해 시나리오를 제시하고 분석한다.

In mobile Internet banking service through wireless local area network, security is a most important factor to consider. We describe the development of mobile banking service using Personal Digatal Assistant (PDA). In order to increase the strength of encryption, we adopted hybrid approach where both of the public key algorithm and the secret key algorithm are used during the transaction among PDA, banking server and authentication server.

With the role of cell phones in today's society as a digital personal assistant as well as the primary tool for personal communication, it is possible to imagine the involvement of cell phones in almost any type of crime. The progression of a criminal investigation can hinge on vital clues obtained from a cell phone. This paper will be concentrated on CDMA system phones and focus on the data extraction for cell phone forensics. Especially, the data acquisition method of JTAG interface access to memory chip will be covered.

컴퓨터기술은 어디로 가고 있는가? 이 물음에 대한 답은 바로 입는 컴퓨터일 것이다. 입는 컴퓨터는 완전한 기능을 갖춘 컴퓨터를 몸에 지니고 다니면서 언제 어디서나 원하는 일을 할 수 있게 해준다. 처음 만들어진 컴퓨터는 큰 건물만 했으나 책상 위에 올려놓을 정도에서 들고 다닐 수 있는 크기까지 작아졌다. 그러나 노트북 컴퓨터는 아직 휴대하기에는 불편함이 많다. 이 문제를 해결한 제품이 PDA(Personal Data Assistant)이다. (중략)

This paper suggests a TCP/IP-based remote data monitoring system, which combines PDA (Personal Digital Assistant) and WLAN (Wireless Local Area Network) technologies. Wireless PDA devices are used for remote monitoring of wireless communication by continuously collecting remote device data transmitted from servers such as temperature, humidity and device status, and displaying them on mobile devices. Therefore, remote data monitoring systems that integrate wireless and wired services provide data collection adaptive to administrators and efficient identification of device status.

In this paper we mention the optimization of MPEG-4 VM (Moving Picture Expert Group-4 Verification Model) GA (General Audio) AAC (Advanced Audio Coding) encoder and the design of the decoder for PDA (Personal Digital Assistant) using MPEG-4 VM source. We profiled the VMC source and several optimization methods have applied to those selected functions from the profiling. Intel Pentium III 600 MHz PC, which uses windows 98 as OS, takes about 20 times of encoding time compared to input sample running time, with additional options, and about 10 times without any option. Decoding time on PDA was over 35 seconds for the 17 seconds input sample. After optimization, the encoding time has reduced to 50% and the real time decoding has achieved on PDA.

Purpose: The purpose of this study was to evaluate the usability of a prototype personal digital assistant (PDA)-based decision support system for the management of obesity through usability testing with end-users (Advanced Practice Nurses [APNs]) prior to its implementation in clinical settings. Methods: This descriptive study used observational and think aloud techniques to address the research question: what usability problems are perceived by end-users? Five APNs were provided with the scenarios and the list of tasks to evaluate the application. Their verbalizations were recorded through Morae usabil ity software. Data analysis was based on the data captured through Morae, transcriptions, notes, and the end-user survey. Results: End-users completed all the required tasks without encountering a severe usability problem, and agreed that the system was easy to use. clear, concise, and useful. Usability issues that were unrecognized by the developer or usability experts were identified by APNs. The usability problems were categorized according to positive characteristics, negative characteristics, and recommendations. The usability issues were discussed with the project team members, and solutions were suggested to improve the user interface of the PDA-based decision support system before the final implementation. Conclusions: This approach had an important impact on making the system easier to use and more useful from the perspective of design and content. The results of this evaluation provided iterative feedback regarding the design and implementation of the PDA-based decision support system for the management of obesity.
