Contemporary workspace is configured in various manners according to working patterns, collaborative or independent nature of works, group-wise working styles and culture, the size of the group, and so on. On the other hand, conventional office space has tended to be a monolithic single space packed with various types of works. This change reflects what has happened to the meanings and structures of office space. The ubiquitous computing technique is being applied to the development of the intelligent office as it grows. This leads to the change of intelligent office technology which provides user-oriented spatial service. This paper focuses on the conceptualization and design of service scenarios or the intelligent office based on the user-oriented spatial service paradigm.

Opening special dental office like prosthetic, orthodontics and implant is getting popular from the specialization and ramification on dental service. It shows how changes onpeople's point of view on dental offices as a business and high interesting on aesthetic. The child dental office also specialized from 1990s. It had been divided by not sort of sickness but ages of children. Thus it should support not just basic functions what other dentist of vice does but also comfortable environment to guide children patients' behavior who get afraid easily. However the interior of existing the child dental office was more focused on visual decoration but consideration of space. Thus the space is very superficial and plain, so there is limitation to give suitable environment to children patients. Therefore, from this study, I will research what is the proper space to control children patients' behavior based on well balance of space and decoration designs. Also from the research, I will explain fundamental design ideas on the child dental office space.

This paper introduces the upper stage attitude control system of KSLV-I, which is the first space launch vehicle in Korea. The KSLV-I upper stage attitude control system consists of two electro-hydraulic actuators and a reaction control system using cold nitrogen gas. A proportional, derivative, and integral controller is designed for the electro-hydraulic thrust vectoring system, and Schmidt trigger ON/OFF controllers are designed for the reaction control system. Each attitude controller is designed to have enough stability margins. The stability and performance of KSLV-I upper stage attitude control system is verified via hardware in the loop tests. Hardware in the loop tests are accomplished for perturbed flight conditions as well as nominal flight condition. The test results show that the attitude control loop of KSLV-I upper stage is very stable and the attitude controllers perform well for all flight conditions. Attitude controllers designed in this paper have been successfully applied to the first flight of KSLV-I on August 25, 2009. The flight test results show that all attitude controllers of the KSLV-I upper stage performed well and satisfied the accuracy specifications even during abnormal flight conditions.

Korea Pathfinder Lunar Orbiter (KPLO), also known as Danuri, was successfully launched on 4 Aug. from Cape Canaveral Space Force Station using a Space-X Falcon-9 rocket. Flight dynamics (FD) operational readiness was one of the critical parts to be checked before the flight. To demonstrate FD software's readiness and enhance the operator's contingency response capabilities, KPLO FD specialists planned, organized, and conducted four simulations and two rehearsals before the KPLO launch. For the efficiency and integrity of FD simulation and rehearsal, different sets of blind test data were prepared, including the simulated tracking measurements that incorporated dynamical model errors, maneuver execution errors, and other errors associated with a tracking system. This paper presents the simulation and rehearsal results with lessons learned for the KPLO FD operational readiness checkout. As a result, every functionality of FD operation systems is firmly secured based on the operation procedure with an enhancement of contingency operational response capability. After conducting several simulations and rehearsals, KPLO FD specialists were much more confident in the flight teams' ability to overcome the challenges in a realistic flight and FD software's reliability in flying the KPLO. Moreover, the results of this work will provide numerous insights to the FD experts willing to prepare deep space flight operations.

According to office building design in Korea, building exterior and office automatic systems through introducing IB system have been improved. However, the lower floors of a building are functionally easy to transfer but actually functions as an enterance. Although at takes a large investment by the owner or enterprise, mainly the tenants and neighbors are in a broad sense the actual users. In this point of view, the lobby of an office bulidling which is the connection between the exterior as a public space and the interior as a private area, does not only have the function of an enterance but also has to be an image of the enterprise or the building itself. Therefor the lobby must contain various functions of space.

The stress from the office environment comes from the most psychological things. Therefore, the purpose of this study is to research the psychological effect of natural element for office worker's psychological stability. This study is focused on the light, sound, air, temperature, plant, and water. Perception of these natural elements through the senses of sight, auditory, smell, and touch is effect on human body and mind directly. The application of natural elements provide a health of office workers. The result will show that, with application of the natural element, the rest space will be more powerful for health of workers. And also combination of natural element and geometric pattern will be very useful to prepare healing environment on the rest space

Objective: This study aims to investigate the correlation between office and work environment satisfaction levels and workers' musculoskeletal symptoms by conducting surveys asking office workers to state their musculoskeletal symptoms and office and work environment satisfaction levels. Background: The increased number of office workers and their indoor work hours using computers have led to new understandings of the importance of office environment including its temperature, humidity, noise levels, lighting and quality of air, and work environment including monitor arrangement, space arrangement and the functions of desks and chairs. Method: Specific details on office work, office environment satisfaction levels, work environment satisfaction levels, musculoskeletal symptoms, absence from work and treatment due to musculoskeletal related symptoms were analyzed based on the survey answers given by 397 office workers who were the subjects of this research. Results: Office workers showed different characteristics of musculoskeletal symptoms depending on their gender, age, work experience, office hours, break time and time spent on computers. Also, differences in symptoms were found for workers'with different satisfaction levels for office environment (temperature, humidity, noise levels, quality of air, lighting) and work environment (location of monitors, area and display of office space, chairs and desks). ANOVA shows the differences between groups of subjects classified by the experience of work-absences and treatments or pain complaints. Conclusion and Application: Relationship between workers' satisfaction levels with the office and work environment and their musculoskeletal symptoms is expected to be served as essential data for systematic management of the workplace.

Under the establishment and operating regulations of school presented only minimum standard for the founding of the school. Therefore, It is intended to suggest the reasonable space standard of the school facility, through comparison & analysis of facility standard in each city and provincial education office. Especially, The facilities standard of Chungcheongbuk-do Office Of Education has been exceeded standardization of architectural space which is proposed the Ministry of Education, and they has made the various learning space reflected creative ideas by designing all of the new school competition since 2000. In order to deal with reacting the changing method of studying like as the examples of Middle & High school in Chungcheongbuk-do, they need to set aside the enough required area for a head of students and the common space which is more than 40% in the total area according to the various learning space, securing the supporting facilities, and break & movement of the students. Moreover, Each of the city and provincial education offices are needed to establish the standardization of proper area for space organization of the planned school throughout upcoming competition.
