This study was conducted to look into consulting areas that can secure loyalty customers by clarifying relations between perceived quality factors, brand image and customer loyalty in terms of a multi-function printer. To accomplish the study purpose, this study carried out a validation analysis, a reliability analysis and a structural equation model analysis by setting up a study model and a hypothesis based on precedent studies and collecting data from purchase decision-makers. The findings of the study are summarized as follows. First, effects of perceived quality components of a multi-function printer on brand image were product quality, sales man's service and service quality in order of majority. Second, brand image of a multi-function printer has a positive impact on customer loyalty. This study is meaningful as it expanded the scope of study related to a multi-function printer up to the administrative field. This study is expected to help industries, who have similar business structure of a multi-function printer, establish a business strategy and support practical work and administrative consulting.

Recently, as the noise problems of mechancial structures have been more serious, much studies are being carried out on the identification of noise sources and the reduction of noise level. In this paper, as the application of frequency analysis, the multi-dimensional spectral analysis method is applied to daisy wheel printer to identify the noise sources, and the relationship between sound pressure and vibration of printer is found in narrow and overall frequency range. The results of this study are compared with those of frequency response function method, thus, the applicability of multidimensional spectral analysis method is verified. It can be found, in a overall frequency range, that the vibration of platen have the worst effect on noise level, and the noise level reduction of 6dB, 7.9dB is obtained by changing the platen thickness to 2mm, 4mm, respectively.

This paper proposes the method that design CLUT(color look-up table) simultaneously processing gamut mapping and color space conversion using only LUT without complex computation. After we construct LUT composed of scanner gamut and printer gamut, we extend L$\^$*/a$\^$*/b$\^$*/ points based on input L$\^$*/a$\^$*/b$\^$*/ to include input scanner L$\^$*/a$\^$*/b$\^$*/ Input RGB image of scanner is converted into CIEL$\^$*/a$\^$*/b$\^$*/ using regression (unction. CIELAB values of scanner are convened into CMY values including gamut mapping processing without additional gamut mapping using the proposed CLUT. In the experiments, the proposed method resulted in the similar color difference, but reduced the complexity computation compared with processing gamut mapping and color space conversion respectively

Caused by the development of IT environment, the frequency of using the embedded machines is increasing in our regular life. A typical example of these embedded machines is a Multi Function Copier and it has various functions; it is used as copier, scanner, fax machine, and file server. We would like to check the existence of and the way to abstract the data that may have been saved through using the scanner of the multi function printer and discuss how to use those data as the evidence.

This study is about what process and methodology could make UI designer be able to achieve the interface which considers user's mental model through implementing corporate line-up model, when people design an interface between product of multi-function printer and user. The most important concern of UI designers who are dealing with an interface between product and user is how they can make product system image match user's mental model so that users can utilize products without any confusion and discomfort. If concept model which designers bring up and mental model which users expect and recognize could be of one accord, then users can feel ease of use toward products. The understanding and observation for user behavior and use pattern is prerequisite to develop user-centered interface between product and user. However, UI designers do design interface from their own perspective and assumption in many business areas, and users do not react as designers assumed and intended in many cases or examples. This study is to find inappropriate system images against users' mental model on basic function of multi-function printer, and the relationship of system image and user's mental model is diagramed to build up a hypothesis. The hypothesis from this study is validated through evaluation of domestic and international users. In addition, two suggestions to improve usability problems revealed from user test are proposed. The optimal solution is designed based on the result of user evaluation and consideration of many user environments, and then it is implemented to line-up product. In conclusion, this study considers how UI designers can create system image which is close to user's mental model.

디지털 복합기는 프린터, 복사기, 스캐너, 팩스 등의 장치가 결합되어 있는 임베디드 장치로써 출력, 복사, 스캔, 팩스 외에 네트워크 통신을 이용한 원격 유지보수, 다중 사용자가 맞물려 있는 장치이다. 이러한 디지털 복합기는 최근 기업 및 공공기관에서 업무의 효율성 증대와 경비절감을 위해 중요한 문서를 처리하는 장비로 널리 보급되고 있다. 하지만 산업 스파이나 공격자들에 의해 중요한 문서들이 외부로 유출되면서 기업의 피해가 증가하고 있다. 따라서 본 논문에서는 디지털 복합기에서 발생할 수 있는 다양한 보안 취약점 및 보안 위협을 기밀성, 무결성, 가용성, 부인방지 측면에서 분석하였다.

오늘날 우리 사회는 정보 유출에 따른 심각한 현상들을 겪고 있으며 기업들은 정보 유출을 막기 위해 많은 비용을 들이고 있는 실정이다. 정보 유출 중 문서 및 팩스를 이용한 1 차적인 문서 유출을 막기 위해 과거 기업들은 여러 방법들을 사용하여 왔다. 특히 기업은 보안과 동시에 업무 효율 그리고 비용 문제까지 고려 해야만 하는 실정이다. 본 고에서는 그러한 문제점들을 고려해서 현재 사용되어 지고 있는 보안 시스템의 개념과 운영 방법들을 논하고 그에 따른 개선점등을 바탕으로 새로운 RFID 을 이용한 복합기 보안 시스템을 제안하고자 한다. RFID 를 통해서 서버 인증을 실시하고 복합기에서 이를 바탕으로 사용 허가를 주는 방법으로 출입문에서 시작하여 주변기기로 이어지는 통합적인 시스템이다. 이는 보안성 및 경제성을 고려할 때 기업의 새로운 복합기 보안 시스템으로 정보 보안 및 기업의 경쟁력을 향상 시킬 수 있을 것으로 기대된다.

Conventional eco-design has been implemented based only on the environmental aspects of a product. Key components of a product identified from the analysis of the environmental aspects have been the target for improvement in the conventional eco-design. The use of eco-design index (EDI) considering both the environmental and economic aspects, and utility value (UV) of a product can be envisaged as an alternative way of implementing and assessing the eco-design. The objective of this study was to propose the logic of the EDI and apply it to the components for performing printing function of the multi-function printer. The EDI was formulated by quantifying the UV, life cycle environmental impact (LCE) and life cycle cost (LCC) of the components of a product, here components of the printer. Of the eight components investigated, roller was identified as the best performing consumable in both the environmental and economic aspects. However, its UV was the lowest among the eight. The EDI of the roller was mere $4^{th}$ in ranking out of the eight. Transfer belt ranked $8^{th}$ and $5^{th}$ in the environmental and economic aspects, respectively, while $2^{nd}$ in the utility value with its EDI ranked $3^{rd}$. This indicates that not only the environmental aspects but also economic and utility value aspects should be considered when identifying the key components for improvement in the eco-design.
