The purpose of this paper is to propose a method of rest to reduce work load of night shift workers for night shift work. The experiment was carried out 10minutes preparing time, 45minutes first work, 10minutes first rest, 45minutes second work, 10minutes second rest between 2 and 4 o'clock that the lowest physiological function of workers. The methods of rest set up as four patterns (1) non-action rest (2) non-action rest + listening music (3) action rest + non-action rest, (4) action rest + non-action rest + listening music. For the measurements of experiment, heart rates(R-R interval), critical flicker fusion frequency(CFF), blood pressure, oral temperature, reaction time and error rates were considered as criteria for work performance. As a result, action rest + non-action rest and action rest + non-action rest + listening music were more effective to reduce work load additional work than non-action rest and non-action rest + listening music.

The majority of next generation information systems will be working on portable mobile devices such as smartphones. REST Open API web services have quickly become popular among mobile application development. The use of REST web services are not only growing in popularity but totally changing the way of mobile applications development. This is because REST web services could be used in application development as a form of building blocks, which is completely independent, compatible, to any platforms. With this strength, REST web services encourage third party application to build add-on functionality. This research proposes the use of REST web service to replace the use of socket APIs into major internet communication APIs. To this end, this paper also provide performance evaluation of the REST web services compared to the conventional socket APIs, focusing on scalability by analytical and experimental evaluations. Finally, we summarize the possibility whether REST Open API web services have enough performance as future major internet communication primitive APIs.

This study aims to analyze the actual state, the satisfaction index, and the satisfaction factor of the residents in the apartment adopting thematic outdoor rest space design. This study also proposes the basic data for the standard of resident-centered rest space design, not designer-centered or fashion-followed design. The results are as follows : First, most residents use near by rest space, and more use occur during the evenings; 17 hr. ∼ 21 hr. Most of residents use the rest space with their children, partner, or family. Residents usually take walks and take a rests in the rest space. Most residents use the rest space quietly. Of the rest facilities in the outdoor rest space, benches are most used, walks and pergolas are more frequently used. But waterscape facilities are not particularly used. The satisfaction index of the outdoor rest space is generally low. However, the satisfaction index of the rest space and facilities type shows that the evaluation of rest facilities(e.g. benches) is high. The satisfaction index of the decoration shows that the evaluation for the color and design of facilities is high. In the satisfaction index of the physical environment, the item about the size of rest space is highly appreciated. In the mental satisfaction index of the rest space, the item about whole atmosphere is highly appreciated. Of the factors affecting the general satisfaction index with outdoor rest space, the factor of physical environment is the most important independent-variable. Physical environment and facilities are more important influential factors than the atmosphere of outdoor rest space. In the future, the practical study searching for the preferences of the residents and the activation of use should be preceded.

The goal of this study was to compare wrist posture, muscular loads and perceived comfort among wearable wrist rest (WR), general wrist rest(GR), no wrist rest(NR) during keyboard and mouse use. Thirteen subjects performed text editing task in three test conditions: wearable wrist rest(WR), general wrist rest(GR), no wrist rest(NR). During text editing task, the right wrist posture was recorded by an electrogoniometer and the muscle activity in upper trapezius, anterior deltoid, extensor digitorum, extensor carpi ulnaris were recorded by electromyography. After all of the tests, the subjects rated perceived comfort. Working with wearable wrist rest(WR), compared to no wrist rest(NR) and general wrist rest(GR), decreased wrist radial/ulnar deviation and also decreased muscle activity in upper trapezius and anterior deltoid. At the same time, in work with wearable wrist rest(WR), the subjects rated more comfort at 5 of 8 body locations(shoulder, upper arm, wrist, hand, body).

The Beautiful rest room is simple how to think. We need to understand that excretion is important as much as eating. When we didn't have foods, eating was important in itself no matter what our lives environments. But now we want to eat in more dignified and more cultural place. Most of restaurants spend money on adjusting place for the consumes' desire. It is same way about rest room, it is time to change our rest room to place of rest and speculation over the place which we fix our natural urge. We can fix our natural urge, take a rest, and get creative ideas in more convenient, more healthy and more comfortable. It is time for us to change out thought about rest room; it is not dirty and stink place, but civilized living place like developed country. Also, we need new concept to take a triangular position about rest room is one of structure over just decorations. This research suggest new public rest room without precedent based on instance analysis about rest room inside and outside the country.

PURPOSES : In this study, design elements of rest areas for drowsy drivers are classified and appropriate criteria for each design element are presented. METHODS : By comparing and analyzing the design criteria for rest areas, the most appropriate installation criteria were suggested by considering the driving patterns of rest area users. RESULTS : As a result of the study, elements influencing the design of rest areas for drowsy drivers are suggested such as installation location and installation type. In addition, proper separation distance between resting areas was suggested considering vehicle flow, users' fatigue and physiological needs. Other criteria for rest areas were also suggested. CONCLUSIONS : Proper safety facilities were not installed in rest areas because appropriate criteria were not established. In this study, design elements were derived and installation criteria were designed so that rest areas could be used safely and conveniently.

Prolonged immobilization leads to significant weakness and atrophy of the skeletal muscle and can also impair the recovery of muscle strength following injury. Therefore, it is important to minimize the period under immobilization and accelerate the return to normal activity. This study examined the effects of combined heat treatment and rest-inserted exercise on the muscle activity of the lower limb during knee flexion/extension. Twelve healthy subjects were assigned to 4 groups that included: (1) heat treatment + rest-inserted exercise; (2) heat treatment + continuous exercise; (3) no heat treatment + rest-inserted exercise; and (4) no heat treatment + continuous exercise. Heat treatment was applied for 15 mins prior to exercise. Continuous exercise groups performed knee flexion/extension at 0.5 Hz for 300 cycles without rest whereas rest-inserted exercise groups performed the same exercise but with 2 mins rest inserted every 60 cycles of continuous exercise. Changes in the rectus femoris and hamstring muscle activities were assessed at 0 and 2 weeks of treatment by measuring the electromyography signals of isokinetic maximum voluntary contraction. Significant increases in both the rectus femoris and hamstring muscles were observed after only 2 weeks of treatment when both heat treatment and rest-inserted exercise were performed. These results suggest that combination of various treatment techniques, such as heat treatment and rest-inserted exercise, may accelerate the recovery of muscle strength following injury or immobilization.

This paper search the difference between the village groves for enclosing and the village groves for rest in Chinan-Kun region. Both charged 72.5%(37 groves) of all(51 groves). The form of village groves for rest was various, but that of those for enclosing was linear. The average area of village groves for enclosing was 2,755.4$m^2$ and that of those for rest was 661.2$m^2$. So village groves for enclosing was 4.2 times larger than that of those for rest. In function of village groves, it was identified that function of complementing vacant part was more important than of rest in human settlement region. In the transformation of village groves, the village groves for enclosing were transformed into other productive use than those for rest. Although the worship service were performed annually in the past, that were almost disappeared in present. The forest state of village groves were almost deciduous ones. In vegetation structure, the number of upper trees of village groves for enclosing was 5 times more than that of those for rest. In average appearing rate of upper trees, the village groves for enclosing was 2 times more than that of those for rest. The most principal dominent species of both in upper trec was Zelkova serrata. The species showing highly appearing rate of upper trees were Zelkova serrata, Carpinus tschonoskii, Celtis sinensis, Qercus acutissima, Pinus densiflora, Castanea crenata, Salix glandulosa. etc.
