Simulation techniques are used to improve the productivity of a textile factory. A simulation model is developed for the analysis of investment for dyeing process equipment, such as dryers and bleachers. For modeling and analysis, AIM (Analyzer for Improving Manufacturing) is used. AIM is a manufacturing oriented simulation software developed by Pritsker Corp. AIM provides interactive model building and simulation, automatic animation, and powerful graphic outputs. thereby, drastically reducing modeling efforts and also enhancing communication capabilities.

정보화 산업의 급속한 발전을 통하여 무수히 많은 양의 정보들이 디지털화되어 왔고, 이러한 정보를 인식하기 위해서 인간은 멀티미디어나 컴퓨터를 통해 디지털화된 환경에 접속하게 되는데, 이는 시각과 청각을 통해 디지털화된 정보를 인간에게 전달하여 준다 이러한 시각과 청각을 이용한 정보 입출력 장치를 장시간 사용할 경우 정신적으로나 육체적으로 피곤함［l］과 지루함을 느끼게 되고, 장시간 사용이후에도 외부환경에 대한 반응이 일순간 둔감해질 수도 있다.(중략)

본 논문에서는 단순히 필요한 정보를 얻기 위한 수준에 그쳤던 현대의 인공지능을 SER (Speech Emotion Recognition) 기술을 이용하여 사용자와 직접적으로 대화하는 형식으로 발전시키고자 한다. 사용자의 음성 언어에서 감정을 추출하여 인공지능 분야 및 챗봇과 대화함에 있어 좀더 효과적으로 해석할 수 있도록 도움을 준다. 이것을 대화형 시뮬레이션 게임에 접목시켜 단순한 선택형 대화 방식이 아닌 구어체로 대화하며 사용자에게 높은 몰입도를 줄 수 있다.

The goal of this study is to seek an educational method that bring major improvements of the tactical communication through setting a definition on the tactical communication and developing ways of the communication methods to petty officer majoring students in community college level. The study is formed a concept of the tactical communication based on the tactical soften influence and, set up three steps; Goal - Act - Achieving the purpose. The study clarifies that the tactical communication is formed by repeating three steps of 'Recognition - Understanding - Regarding - Act.' To suggest an efficient way of the tactical communication by reducing the repeating communication steps, the study proposes 'OODA loop' communication. The curriculum of Petty officer major students has three steps, Change - Apply - Present steps, with using the concept of 'OODA loop.' The curriculum method offers a way of improvement state on interpersonal and problem-solving abilities. This education method presents variety developed OODA loop situations to minimize the act step on conversing informations through objective perspective and helping faster decision making process.

The digital library operated in the environment of computer-mediated-communication offered new successful alternative plans for the field and communication methods of the information services that have been provided by the traditional library and this causes the traditional library to move to the new paradigm. In this situation, the information services of the digital library raised the necessity for the communication channels that would cope actively on the spot and for the extention of information services that would supply an unspecified number of the general public with a considerable extention of information services that neglect time and space. This study looked into the communication channels in general for interactions between the digital library and the users in the environment of computer-mediated-communication and observed patterns of communication chennels that the digital library could supply. For the development of the communication model in the digital library, the study presented the communication model for effective information services.

Smart home System is shirt-sleeve, the automatic control systems, computer network system and network communication technology in the integration of network intelligent home control system. Intelligent household will let users have a more convenient means to management of domestic equipment, for example, through the house, wireless remote control, touch screen phone and Internet or speech recognition control household devices, more can perform scene operation, make more equipment form linkage. In this paper, we propose the intelligent household various kinds of equipment within each other can communication, do not need to user command according to different state interactive operation, thus to bring the greatest degree of user efficient and convenient, comfortable and safe.

Objective: This study examined that general characteristics such as gender, age, period of stay at an institution, size of facility, and temperament and attachment affect young children's development under institutional care. Methods: A total of 94 young children (ages 2-4years), who live in 32 institutions in Seoul were assessed on their development using the Korean-Age & Stage Questionnaire. Pearson productmoment correlation analysis, and multiple regression analyses were used for data analysis. Results: The major findings of this study were as follows: first, a longer period of stay at an institution had more positive effects on the development of communication. Facilities with more than 60 children had lower communication, gross motor, and fine motor development compared to facilities with less than 60 children. Second, social temperament had positive effects on communication, problem solving, and personal-social development. Emotional temperament had no effects on all development areas. Third, attachment had positive effects on all development areas. Lastly, social temperament and attachment had interactive effects on communication, gross motor, problem solving, and personal-social development. Conclusion: These results imply that caretakers in institutions should give developmental mediation services for considering temperament and facilitation of attachment.

Recently, NMEA2000 became the de facto standard of the communication protocol for the instrument level network in vessels, and it is anticipated that most of the vessels will be equipped with the sensors and actuators based on this protocol. The conventional serial communication specifications such as RS-232, RS-485, or even NMEA0183 are single-talker/multiple-listener and interconnection among multiple sensors and/or actuators usually results in a bundle of wires. On the other hand, NMEA2000 is a true bus type(multiple-talker/multiple-listener) protocol and theoretically up to 256 instruments can be hot-plugged. With the advent of the protocol, it is necessary to consider a new type of monitoring system for the instruments in vessels: In most traditional serial communication environments, a dedicated monitor or user interface was necessary for each sensor or actuator as it was simply not easy to collect data in a single place. With NMEA2000, the collection of various types of information is simple. An embedded system can be employed to combine, to arrange and to display informations from various types of devices. Assuming that the actuators and sensors on a vessel are interconnected by NMEA2000 standard, we devise a tentative interactive vessel monitoring system in which the following 4 kinds of informations are collected and delivered: the navigation, engine, weather and tanks informations.
