This article proposes a novel shift automation mechanism for an automated manual transmission (AMT). The development of an automated manual transmission is currently being paid considerable attention by vehicle manufacturers, with the prospects of combining the comfort of an automatic transmission and the high efficiency of a manual transmission. In order to automate the shift mechanism of a manual transmission, the proposed shift automation mechanism consists of two electric motors, cross shaped pinion gears, rack type shift rails, and a ball splined hollow shaft. First we describe the shift mechanism and operating principles of a manual transmission to investigate important design criteria for the shift automation device. And a new shift automation mechanism is described with its structure, elements, and operating principles in detail. Using a conventional manual transmission, we develop a full three-dimensional CAD model of an AMT which includes main components of the manual transmission and the designed shift automation mechanism. Finally we investigate the operating performances and feasibility of the designed AMT by a dynamic analysis.

The purpose of this study was to determine the factors which affect older people's innovativeness toward technologies and factors which affect their demand of home automation system. The study collected data from 289 persons who are 50 years and older with experience living in an apartment currently or past. Innovativeness toward technologies of respondents were low level and the significant factors which affect their innovativeness were age, education, employment, marital status, current housing types, health status of self and spouse, consideration of home automation system for a newly-moved house. Education, employment types, consideration of home automation system for a newly-moved house, and plan for moving were the major factors which affect demand of home automation system. Also, older people's innovativeness toward technologies was the most important factors which affect demand of home automation system. Th results of this study explained that high technologies which are adopted in residential environment should be considered target consumers' abilities and attitudes for acceptance toward new ideas. Especially, for older consumers, various ideas to expand their understanding of new technologies should be developed and the positive effect of technologies to increase the qualify of their later life should be educated.

This study purposed to establish the history of library automation through multilateral analysis and systematic description of the development process of university library automation in Korea and to analyze problems in the development process. In the research, we conducted literature review, investigation of university homepages and telephone interviews. Based on previous researches and the current state of university library automation, the development process of university libraries was divided into 'the stage of introduction,' 'the stage of growth,' 'the stage of stability' and 'the stage of take off.' First, the current state of university library automation was analyzed through literature review, and 109 libraries at private universities in Korea were sampled for data analysis.

본 논문은 LS산전 고압인버터의 국내외 현장 전용화 사례에 대해 기술한다. 고압인버터는 대용량 고전압 전동기를 구비한 중요부하에 주로 적용되며 단독운전보다는 다수의 고압인버터가 연동 운전하는 현장에 설치되는 경우가 많다. 이러한 현장에는 표준제품이 아닌 전용화 기능을 포함한 제품이 출하가 된다. 자사 LS MVD는 각종 산업설비와 국책연구기관의 시험설비 그리고 발전소 수처리 시설 등 국가기간시설에 많이 적용이 되며 매년 70여대 이상의 MVD가 국내외 전동기 부하에 신규로 설치되어 운용되고 있다. 본 논문에서는 주목할만한 현장의 전용화 사례에 대해 설명하여 향후 고압인버터를 적용하고자 하는 고객이나 고압인버터에 관심이 있는 엔지니어에게 고압인버터에 대한 이해도를 높이고자 한다.

Construction automation can be an effective alternative for the lack of skilled labor and loss of productivity. With such a background, Korean government has provided a lot of financial supports for the development of construction automation technology. However, despite of those efforts, automation systems at construction sites have rarely been employed. This is because the systems have not been developed with full consideration of the needs and environments on construction sites. Thus, the purpose of this study is to identify the critical success factors for efficient development of construction automation systems. This study compares and analyzes key factors for automated construction system(ACS) and construction information system(CIS). As a result, 'stability and reliability' in the ACS showed the highest importance while 'manageability' in the CIS was. Consequently, for the successful introduction of the ACS, technical capability and stability should be firstly considered to cope with dynamic construction environment, while the CIS should be built to enable efficient management and use of information. The result of this study can serve as an evaluation base for the current construction automation technologies and an index for more efficient technology development in the future as well.

With digital technology innovation, increased data access and mobile network use by consumers, products and services are changing toward pursuing differentiated values for personalization, and personalized markets are rapidly emerging in the fashion industry. This study aims to identify trends in digital customized automation technology by deriving types of digital customizing and analyzing cases by type, and to present directions for the development of digital customizing processes and the use of technology in the future. As a research method, a literature study for a theoretical background, a case study for classification and analysis of types was conducted. The results of the study are as follows. The types of digital customizing can be classified into three types: 'cooperative customization', 'selective composition and combination', 'transparent suggestion', and automation technologies shown in each type include 3D printing, 3D virtual clothing, robot mannequin, human automatic measurement program, AR-based fitting service, big data, and AI-based curation function. With the development of digital automation technology, the fashion industry environment is also changing from existing manufacturing-oriented to consumer-oriented, and the production process is rapidly changing with IT and artificial intelligence-based automation technology. The results of this study hope that digital customized automation technology will meet various needs of personalization and customization and present the future direction of digital fashion technology, where fashion brands will expand based on the spread of digital technology.

This paper concerns the problem of simultaneous fault detection and disturbance reject control(SFDDRC) for a class of linear time-invariant system. In the framework of fault detection, residual generators are required to be robust to disturbances existing in the system. Different from most of the existing simultaneous fault and control(SFDC) methods, SFDDRC rejects the influences of disturbances on residual generators by disturbance observer-based control(DOBC). This not only effectively improves the accuracy of fault detection, but also solves the problem that most of the existing SFDC methods require that the disturbance must be bounded. Finally, a numerical example is given to verify the validity of the method.
