Rapid social change in economy, society and information technology takes the initiative of changing office formation. It also requires new change in workspace function for the office workers. This research is about the change of office formation chronologically according to the change in economy, society and cultural diversity. The study also shows the directions for the workspace design considering the new demand and flow of the new office formation. Mobile Office, Virtual Office and Moduler Office are the new office formation. Also, the new workspace requires the common space where the workers can communicate diversely and share their knowledge and ideas, enhancing collaboration and productivity of the new workspace.

This work discusses the numerical analysis, the design and experimental test of the SMA (Shape Memory Alloy) actuator along with its capabilities and limitations. Convection heating and cooling using water actuate the SMA element of the actuator. The fuel such as propane, having a high energy density, is used as the energy source for the SMA actuator in order to increase power and energy density of the system, and thus in order to obviate the need for electrical power supplies such as batteries. The system is composed of a pump, valves, bellows, a heater (burner), control unit and a displacement amplification device. The actuation frequency is compared with the prediction obtained from numerical analysis. For the designed SMA actuator system, the results of numerical analysis were utilized in determining design parameters and operating conditions.

In this paper, the energy saving illuminator with a function of crime and fire prevention is developed. This illuminator is communicated with a superintendent's office by wireless communication and the informations being archived by the illuminator are transmitted to a superintendent's office. If this illuminator is established with only one in a lecture room or a office room, a wireless network with saving a energy and preventing crimes and fires can be constructed.

분산처리 시스템은 네트워크로 연결된 프로세서들로 구성되며, 시스템 내의 각 프로세서는 고유한 클럭을 갖는다. 글로벌 시간 기준으로 볼 때 수행중인 프로세스가 유지하는 시간은 분산시스템 각각 차이가 있을 수 있으므로 일관성 있는 시간관리가 필요하다. 본 논문에서는 TMO-eCos를 기반으로 하는 분산 처리 시스템에서 각 분산 시스템간 발생할 수 있는 클럭의 불일치 문제를 해결하기 위한 클럭 동기화 기법에 관해 논한다. 점진적인 클럭 동기화 알고리즘을 구하기 위해 마스터 노드의 클럭을 글로벌 클럭으로 가정하고 슬레이브 노드들은 마스터 노드의 클럭으로 동기화하는 방법에 대하여 정의하였다. 정의한 알고리즘을 시현하기 위한 분산 노드 간 로봇 제어 프로그램을 소개 한다.

The need of Home-Office is increasing according to the technology and communication system being developed. It is necessary to develop space program and home furniture design for Home-Office. The purpose of this study was to investigate sjpace condition for Home-Office and Home-Office furniture, and to examine preference and opinion on Home-Office. The results this study can be summarized as follows: 1) An isolated space such as a study was the most preferred for Home-Office. The proper size of Home-Office space in residential interior was over 3.3m$\times$3m. 2) The system furniture which is enable to store OA system, and to have efficient work space was preferred. 3) The preferred color of system furniture was natural wood tone, and the most preferred color of chair was blue. 4) It was assumed that the possibility of Home-Office is increased in the new future.

OOXML-based MS-Office digital files are extensively utilized by businesses and organizations worldwide. However, OOXML-based MS-Office digital files are vulnerable to forgery and corruption attack by including hidden suspicious information, which can lead to activating malware or shell code being hidden in the file. Such malicious code can cause a computer system to malfunction or become infected with ransomware. To prevent such attacks, it is necessary to analyze and detect the corruption of OOXML-based MS-Office files. In this paper, we examine the weaknesses of the existing OOXML-based MS-Office file structure and analyzes how concealment and forgery are performed on MS-Office digital files. As a result, we propose a system to detect hidden data effectively and proactively respond to ransomware attacks exploiting MS-Office security vulnerabilities. Proposed system is designed to provide reliable and efficient detection of hidden data in OOXML-based MS-Office files, which can help organizations protect against potential security threats.

The purpose of this study is to analyze content of curriculum for Office Administration offered in many Secretarial Science & Office-related department at junior colleges. To analyze the curriculum Office Administration, the study focuses on IAAP's contents of Office Systems and Administration and NVQs' contents of Office Administration. which has been selected as a subject for national vocational qualifications in USA and Britain separately. The result of this study are summarized below: 1. IAAP's contents of Office Systems and Administration is divided into two main categories which are an Office Technology and an Office Administration/communication. 2. Whereas, Britain's NVQs contents of Office Administration is divided into 4 parts, which are Basics Concepts in Administrative Office Management, Managing Human Resources, Managing Administrative Services, and Managing Administrative Systems. 3. To provide indepth knowledge of Office automation in today's office environment, the curriculum of Office Administration should include both the theoretical and practical aspects of office works.

Purpose: The purpose of this study is to determine the importance and priority arising from the relationship between MRO-office supplies franchisor ("franchisor") and franchisees through an in-depth investigation. In particular, with respect to the MRO-Office franchise industry, we would like to make meaningful contributions in the decision-making process by comparing and contrasting factors that affect the importance and priority of communication, conflict, support and satisfaction through AHP analysis. Research design, data, and methodology: After completion of AHP analysis, the study will also identify factors in order of priority and factors of importance between the franchisor and franchisees. Another purpose of this study is to evaluate and propose business relationship strategies between the franchisor and franchisees. Through AHP analysis, this study will facilitate the relationship between the franchisor and franchise, and determine the factors of importance and factors in order of priority. Result: This study evaluates the differences and priorities of the two groups arising from the relationship between the franchisor and the franchisees through AHP analysis after separately analyzing the franchisor. In this study, the franchisees find that communication is the most important factor, then support as the second most important factor between the two groups. In contrast, the franchisor finds that support is the most important factor followed by communication between the two groups. Conclusions: This analysis demonstrates the discrepancy in evaluating important factors from the perspectives of the franchisor and the franchisees. The largest discrepancy between the franchisor and franchisees comes from an information system related to communication factors. This effectively means that the franchisor has an understanding of this inadequate information system on the part of franchisees but this understanding is not deemed an important factor. The franchisees recognize and focus on the need to obtain feedback from the franchisor regarding management improvement as the most important factor rather than the ability of the franchisor to guide them through the franchisees' operations. To this end, the franchisor should be more flexible in dealing with the problem of improving the work required by the franchisees. For this study, a survey was conducted on employees of MRO-office supplies franchisor, franchisees, and employees and completed based on AHP analysis.

Since of 2000s, Office furniture have been much changes in the design as the expanding demand for the diversity and variability of office space. Especially, OA System Furniture including Panel System were developed by the shape and configuration considering the members' communication and teamwork. However, It is limited to the situation for the leading manufacturer of office furniture, Most small business cope with a negative policy because development personnel and expense. Thus, Accounted for the majority of the office furniture manufacturing, Small and medium-sized furniture manufacturers are needed measures of development that reflect these realities, rapid and practical. This study suggests redesign in a way that a small and medium-sized furniture manufacturers to overcome the limited design development environment and rapidly respond to changing market conditions. And this study has an intend to develop the Office Panel System.
