Objective: The purpose of this study is to evaluate integral seat desk used in universities through comparison of real dimension values of the desk with KS/ISO standard and questionnaire survey. Background: School furniture that helps students sit comfortably for longer periods of time and allows for better concentration on learning is important. However, seat and desk have been generally designed based on the industry practice rather than user's anthropometry, and seats and desks used in universities of Korea have not been ergonomically evaluated. Method: Real 13 dimensions of the desk used in K University were measured using tape measure and inclinometer, and the dimension values were compared to the KS standard of desk and chair for lecture room (KS G 4210) and ergonomic design principles found in relevant references. Subjective appropriacies and preference for the desk were investigated based on questionnaire survey, in which 121 (male: 91, female: 30) college students participated. Results: Several dimensions for the desk and chair investigated except desk depth and width, leg room width, seat width have not met the KS standard, but all dimensions satisfied ergonomic design principles available in references. The questionnaire survey revealed that appropriacies for desk surface size, seat pan depth, seat pan cushion and backrest curvature were under middle point of 3.0, and that those for the other dimensions showed higher scores exceeding 3.0. Conclusion: The integral seat desk widely used in universities showed some design problems in terms of standards of KS G 2010 and KS G 4210, and ergonomic design principles. Compared to the general desk with separated desk and seat, subjective preference on the integral seat desk was low. Application: This would be used as a valuable guideline when designing or choosing new integral seat desk with high satisfaction of students.

To increase the efficiency of task on the desk, this paper proposes a reconfigurable desk. The proposed reconfigurable desk is based on the Pin Art technology. For the design of the proposed desk, the upper surface of the desk is divided into small units, and then the user easily controls the height of the divided pieces to make desk a desired shape by using the proposed user interface. The Arduino module controls the hardware and the user interface is configured by using Android applications, making it easy for anyone to use. Through extensive experiments, the proposed system shows that various types of deformations are possible and thus the utilization is very high by mounting diverse devices.

As physical condition of students improves, there is a need to develop human body-friendly desk and chair for students. In this study, desks and chairs were manufactured with curved veneer lamination under high frequency heating and pressing, using ten wood species such as Japanese red pine, Korean pine, pitch pine, Japanese larch, yellow poplar, black locust, oak, radiata pine, beech, and birch. The performance of these products were evaluated. The results obtained were summarized as follows; With high frequency heating, the turned lamination of veneers with full size sheet ($3{\times}6\;feet$) prepared by rotary lathe peeling was successfully applied for making the members of desk top, leg frames of desk and chair. Bending strengths of desk tops were relatively greater for yellow poplar, black locust and red pine, which were similar to those of beech and birch. Bending strengths of desk legs were classified into greater species group (red pine, yellow poplar, larch) and lower species group (radiata pine, Korean pine, pitch pine). Compressive strengths of chair legs in parallel direction to the lamination were greater in black locust and larch. On the other hand, differences between outer and inner gap at the top and drawer bottom of desk top were rather larger for the laminations of birch and beech, and less for those of yellow poplar and pitch pine, showing greater stability of open drawer space. In results, yellow poplar, larch, pitch pine and red pine showed good appearance and strength properties at the curved veneer lamination. Accordingly, it was believed that these domestic woods were able to substitute for birch which was being imported for the use of veneer-laminates type furniture.

Objective: This study aims to develop a new desk with a built-in bookholder and desktop-mounted sliding drawer for reducing stress of seated reading postures and to analyze its effect. Background: It is general for readers to bend their back and neck when reading books on desks, which may result in high back and neck postural stress. In addition, postures using vertically layered drawers positioned at the side of users may be awkward. Method: For reducing the postural stress, a new desk with a built-in bookholder and sliding drawer was developed based on a standard of KS G 4208 for student desk. The muscle activities of reading postures on both existing and new desks were measured using EMG, in which seven male and three female college students participated. The postural stress, and musculoskeletal discomfort and ease of usage for existing and new drawers were analyzed by RULA and questionnaire survey, respectively. Results: Compared to existing desk, the muscle activity for the new desk with a bookholder was reduced by 47% when reading books. In addition, musculoskeletal discomforts in the shoulder, neck and low back were significantly lower when using the new desk with a bookholder. Although the stresses for postures using the desktop-mounted sliding drawer and general drawer were not significantly different, the questionnaire survey revealed that the new desktop-mounted sliding drawer is easier to use. Conclusion: A new desk developed in this study significantly reduced postural stress and enhanced subjective preference when reading. Application: This would be useful when developing new desks with low postural stress.

PURPOSE: The purpose of this study was to investigate the effect of distance between trunk and desk on forward head posture and muscle activity of neck and shoulder muscles during computer work. METHODS: Twenty subjects who have healthy conditions were asked to perform computer work in two conditions (distance between trunk and desk was 0 and 15 cm). Forward head angle was analyzed with a SIMI motion analysis system. Surface electromyography recorded the upper trapezius and splenius capitis muscles. The significance of differences in distance between trunk and desk (0cm and 15cm) was tested by paired t-test. The alpha level was set at .05. RESULTS: The results showed that the change of forward head angle was significantly higher during the computer work when the distance between trunk and desk was 15cm than 0cm. The muscle activity of upper trapezius and splenius capitis was also significantly higher during the computer work when the distance between trunk and desk was 15cm than 0cm. CONCLUSION: Our study suggest that the distance between trunk and desk was should minimized for prevention of forward head posture during computer work.
