The purpose of this study is to develop furniture design for work space of Office based on the research of furniture design and the survey on the design of the office furniture. The office furniture Is designed in order to use the space flexibly and for the user design in the work space. The furniture type of solo worker on characteristic kinds of works should have a simple shape and it should be safe and easy to move because it has a structural function. The furniture in office should be designed in consideration of moveing line while working. The development of furniture in office which suit human body should be made in consideration of human factors and the study on furniture design in office. As above mentioned, to research and study on the furniture design of working furniture in office which reduces fatigue resulted from labor for office, human factors aspect should be considered, furthermore psychological, mental approach to Ideal solution should be made.

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.

The number of people working in their own home has been increasing, and this will change the form of house. Therefore, it is necessary to plan the new house for the people working at home, and to offer business related working area. This study was designed to know the office workers preference for spatial characteristics of home office. Data were collected through a questionnaire survey. The subject were 257 office workers living in Seoul area. Frequency, percentage, and MM2 : $\textrm{X}^2$-test were used. The results showed that the place for home-office should be located independently inside house. The desirable size for the home-office might be 3-4 pyung. If the place for home-office share with other places, livingroom of bedroom, it is necessary to develop furniture and partition matching with residential furniture and atmosphere. Office workers prefer U-shaped workstation and coner-shaped workstation.

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.

Objective: The purposes of this study are to investigate ergonomic problems and to propose their improving measures in office environment of big general hospitals. Background: Office tasks have varying risk factors of work-related musculoskeletal disorders (WMSDs). The first symptom resulted from the office work was recognized as an occupational disease in Korea in 1986. Although the symptoms have increased since its first recognition, there has been few study on the effect of office work environment settings. Method: First, the author took pictures of working scenes performed in three big university hospitals. Next, the pictures were analyzed in view point of ergonomics. Based on the analysis, their improving measures were proposed for reducing work stress. Results: The results showed that most physical office environment settings such as dimensions of tables/desks and chairs, leg room, thigh, knee and foot clearances, and chairs used did not satisfy the ergonomically recommended design guidelines. In addition, some clerks placed personal belongings under their desks, put monitors in high position and did not lean against the backrest of chairs in seated tasks, which resulted in poor working postures of leg, back, neck etc. It is recommended that the hospital management should provide their clerks with ergonomically designed office furniture and continuously perform ergonomics training program for raising clerks' recognition for office ergonomics. Conclusion: Most office environment settings investigated in this study were not in good condition in view point of ergonomic design for the settings. Application: It would be useful as basic data for establishing ergonomically good office environment in hospitals.

Recently, a rapid increase of electricity demands have made Transmission & Substation device large-sized. complicated and diverse. Moreover, a rising level of customer's requirement and high growth of industry increase the reliability of electricity service. Therefore on the basis of the case study on the occurrence of fault, the prevention of defects for each device and the analyzing of the outbreak and prevention of systematic breakdown in Sin-Incheon Power Transmission Branch Office, this paper presents some important matters and suggests the method of improvement in design, construction, maintenance, and repairing the Transmission & Substation device.

Recently, Most of the companies and government offices are under consideration about the adoption of cloud office service to actualize the smart work policies. Comparing with traditional office software, a cloud office service have the advantage of the method of payment and coming over the physical limitations. Many cloud office service users tend to adopt an official evaluated the service without doubt. However after deciding to adopt cloud office service, many users are faced with a variety of problems and difficulties practically. In this study, researchers carried out interview about those problems and difficulties after adopting a cloud office service. Consequently, there are several problems and difficulties such as compatibility, document security, document lost and maladjusted to the new graphic user interface between traditional office software and a cloud office service. A cloud office service have still several advantages not only a competitive price but also ubiquitous attributes. Thus, researchers need to study about what kinds of reason variables can solve those problems and difficulties. In existing research, DeLone & McLean have suggested information system success model. They use three independent variables which are system quality, information quality, service quality. Parameters are user satisfaction, intention to use and use. Lastly, dependent variables are net benefits. However in this study, we need to change the scope of measurement. In other words, we have to replace parameters with dependent variables. Simply, user satisfaction, intention to use and use is going to be dependent variables. There are several reasons why we need changing variables. First, we aim at giving a some suggestions to a cloud service providers which independent variables do not work to satisfy for the users. Second, we need to find out how to maximize cloud office service user's satisfaction and intention to use. Third, we should firstly know that relationship between independent variables and dependent variables. Finally, those research results give for the cloud office service provider to solve the cloud office service adopting problems and difficulties.
