The Integration of agent technology and security technology is needed to many application areas like electronic commerce. This paper suggests a model of extended multi-agent engine which supports privacy, integrity, authentication and non-repudiation on agent communication. Each agent which is developed with the agent engine is composed of agent engine layer and agent application layer. We describe and use the concepts self-to-self messages, secure communication channel, and distinction of KQML messages in agent application layer and messages in agent engine layer. The suggested agent engine provides an agent communication language which is extended to enable secure communication between agents without any modifications or restrictions to content layer and message layer of KQML. Also, in the model of our multi-agent engine, secure communication is expressed and processed transparently on the agent communication language.

We aimed to construct and test a structural equation model to analyze the convergence effect of utilizing smartphone technology for Therapeutic Lifestyle Change(TLC) among people with mental illness. A survey using a structured self-questionnaire was conducted from 549 male and 357 female subjects. The data was analyzed by SPSS 23.0 and AMOS 21.0. The model fit for the modified hypothetical model was shown: Q(${\chi}^2/df$)=3.241, AGFI=0.968, CFI=0.970, RMSEA=0.050(95% CI=0.035, 0.065), SRMR=0.048. In modified model from hypothetical model, the opinions about smartphone use affect the willingness to use smartphone applications. And the willingness to use smartphone applications affect dietary and living habits. The result of this study suggests that a convergent study using various delivery systems such as smartphone technology is necessary to implement TLC, which can facilitate the prevention of the metabolic syndrome among people with schizophrenia.

We propose several techniques which can be employed in a 3D fitness program for monitoring and correcting user's posture. To implement a 3D fitness program, improved reference motion generating techniques and visualizing techniques are necessary. First, in order to understand the difference between the user and the reference movement of a professional, a retargeting method between two different body shapes are studied. Second, the problem of self-occlusion, which occurs when using a low-cost depth sensor to represent complex motions, is solved by using a sample database and time consistency. The system proposed in this paper evaluates the user's posture considering the physical characteristics of the user, and then provides feedback to the user.

It is necessary to establish a system suitable for the driving vehicle so that it can effectively search for and modify various data anywhere and anytime by effectively linking communication with the computer system in the running vehicle and to control the equipment properly for smooth operation on a limited platform do. Also, vehicle CAN communication is used to extract system engine information, and data is transmitted using ZigBee for this information transmission. Therefore, OBD-II protocol, which is provided by the vehicle itself, is used for vehicle CAN to obtain vehicle status information and exhaust gas using various sensor information of the vehicle and O2 sensor value, and transmits it to the ZigBee main control system. In this study, we implemented a system that can reduce the battery load damage to the maximum by reducing the power consumption to the maximum, and to monitor the internal state of the vehicle through ZigBee communication with the embedded system for low power vehicles.

Error backpropagation algorithm of multilayer perceptron may result in local-minima because of the insufficient nodes in the hidden layer, inadequate momentum set-up, and initial weights. In this paper, we proposed the ART-1 based fuzzy supervised learning algorithm which is composed of ART-1 and fuzzy single layer supervised learning algorithm. The Proposed fuzzy supervised learning algorithm using self-generation method applied not only ART-1 to creation of nodes from the input layer to the hidden layer, but also the winer-take-all method, modifying stored patterns according to specific patterns. to adjustment of weights. We have applied the proposed learning method to the problem of recognizing a resident registration number in resident cards. Our experimental result showed that the possibility of local-minima was decreased and the teaming speed and the paralysis were improved more than the conventional error backpropagation algorithm.

The uniqueness of Korean funeral culture has produced the problems such as forest indiscreet cemetery development and increase of cemeteries for those without surveying family due to negligent management. To solve these problems, government and social organization have recommended a use of cremation, charnel house and cemetery. The objective of this study is to develop a cemetery information management system which cemetery managers who are GIS laypersons are able to understand GIS functions easily and use conveniently. Cemetery tasks should be done not only in the office but also at the field. In the office, they perform GIS functions like input, modification and so forth using a desktop. And at the field, they perform the functions like simple input, inquiry using a PDA(Touchscreen) that can receive GPS signal. As various open source softwares were used to build the system, the expense was reduced largely, and we could expect the possibility that it can be utilized in more cemeteries by adding more various functions.
