Purpose: This study was conducted for an evidence-based nursing intervention on bed rest period after puncture, by confirming whether there was a difference in scores of headache and back pain between the 1-hour bed rest group and the 6-hour bed rest group following lumbar puncture in patients with leukemia. Method: The subjects were 45 inpatients of the department of hematology at a general hospital in Seoul, from January 1 to March 31, 2005. There were 21 patients in the 1-hour bed rest group and 24 patients in the 6-hour bed rest group. A graphic rating scale was used to measure headaches and back pains. Collected data were analyzed with SPSS 12.0. Non- parametric statistics were used to analyze the data. Results: There was no significant difference between the 1-hour bed rest group and the 6-hour bed rest group in the headache level and back pain level. Conclusion: Therefore, it is considered that a long period of bed rest over 6 hours after lumbar puncture is not a necessary nursing intervention, and repeated studies are required to confirm the result.

REST(Representational State Transfer)는 분산 컴퓨팅 플랫폼 모델이며, 세계에서 가장 큰 분산 응용인 Web에서 사용하고 있는 웹 구조 스타일 모델이다. 현재 웹의 기본 요소는 URI, HTTP, XML(HTML) 이며, REST는 이러한 인터넷 표준만을 사용한다. REST 에서 리소스의 식별은 URI로, 상태는 상태가 표현된 문서(리소스)로써 HTTP를 통해 전달된다. 리소스의 내용은 XML로 기술하며, 리소스 탐색 및 참조에는 HTTP의 표준 메서드인 GET, PUT, POST, DELETE 등만을 이용하는 것으로 분산 컴퓨팅을 모델링하고 있다. 따라서 서비스마다 다양한 메서드를 기억하여야 하는 SOAP 기반 웹 서비스에 비해 REST 모델의 분산 컴퓨팅 응용은 확장성 및 웹 친화성 측면에 있어서 매우 유리함을 알 수 있다.

This study examined the effect of ergonomic heel rest that was designed for drivers who have physical handicap in the low leg muscles or have to drive prolonged hours with frequent foot pedaling. An experiment was designed to test the ergonomic heel rest with traditional foot pedal. Forty subjects participated in the experiment. Electromyography(EMG) was used to monitor the muscle activity and fatigue of right leg, and Electro-goniometer was used to measure the ranges of motions of the knee and ankle. A simulator of driver's seat was built for the experiment and the heel rest was installed on it. In order to examine the low muscle activity and range of motion, subjects used the foot pedal for 15 minutes repetitively for each experimental condition. Another 15 minutes test without the heel rest was also performed for comparison. The Root Mean Square(RMS) and Mean Power Frequency(MPF) Shift were used to quantify the level of muscle activity and local muscle fatigue. In results, statistically significant decreases of muscle activity and fatigue were found in all the low leg muscles. The range of motion of the knee and ankle joint also decreased when the heel rest was used. The mechanism of the heel rest effect was discussed in this study. This type of heel rest can be applied to real driving situation after ensuring the safety, or overcoming the psychological discomfort possibly due to unfamiliarity.

This study investigates the physical characteristics of indoor rest zones using the Space Syntax Method. A conceptual framework is based on analysis of design works presented in competitions(544 rest zones of 24 buildings on 7 campuses). The analysis on the unit type of rest zones showed that they were mostly available as open type, followed by semi-open type and outdoor rest places. On the other hand, by classifying the shape of whole building into traffic lines and nodal points, it was found that the buildings with 3 or more traffic lines have lower availability than others, because the buildings required more nodal points along a little higher complexity and zoning formed at increased nodal points between building masses. The analysis on the location of rest zones on traffic lines showed that hall type was most excellent in the level of availability. Finally, the analysis on the floor height showed that hall-like open rest places and outdoor places like rooftop garden functioned as a factor to enhance the integration of different spaces. In conclusion, this research will help the follow-up studies make spatial creation planning that may enhance the spatial efficiency and availability of Indoor rest zones on the campus.

Highway Rest Areas are envisioned to provide an accessible space for rest and parking for travelers, especially those driving a long distance. In addition, modern highway Rest Areas provide many amenities to highway users, including wifi service, picnic tables, litter barrels, running water, public telephones, and sometimes even free coffee. Various studies were conducted in the domain of Rest Area facility design and their operating costs in different states; however, limited studies were conducted on the maintenance costs of these facilities. Therefore, this study's main objective is to compute the annual maintenance cost of Rest Areas in the state of Nevada. This study also analyzes the main cost categories of the maintenance works. The raw cost data of Nevada Rest Area maintenance from 1990 to 2012 were collected from the Nevada Department of Transportation (NDOT). Results show that the maintenance cost fluctuated over the study period; the maintenance cost decreased from 1991 to 2004 and then increased until 2012. The primary cost categories of maintenance work are labor, equipment, and material costs. Among these, labor cost was the largest category with 56 percent of the total maintenance cost, followed by equipment cost and material cost. The findings of this study may help NDOT and other transportation agencies plan their budget for future Rest Area maintenance activities.

The mu opioid receptor (MOR) has been regarded as the main site of interaction with analgesics in major clinical use, particularly morphine. The repressor element-1 silencing transcription factor (REST) functions as a transcriptional repressor of neuronal genes in non-neuronal cells. However, it is expressed in certain mature neurons, suggesting that it may have complex and novel roles. In addition, the interactions between MOR and REST and their functions remain unclear. In this study, we examined the effects of morphine on the expression of REST mRNA and protein in human neuroblastoma NMB cells to investigate the roles of REST induced by MOR activation in neuronal cells. To determine the effects of morphine on REST expression, we performed RT-PCR, real-time quantitative RT-PCR, western blot analysis and radioligand binding assays in NMB cells. By RTPCR and real-time quantitative RT-PCR, the expression of REST was found to be unchanged by either the MOR agonist morphine or the MOR specific antagonist CTOP. By western blot, morphine was shown to significantly inhibit the expression of REST, but this suppression was completely blocked by treatment with CTOP. In the radioligand binding assay, the overexpression of REST led to an increased opioid ligand binding activity of endogenous MOR in the NMB cells. These results together suggest that morphine inhibits the expression of REST in human neuroblastoma cells through a post-transcriptional regulatory mechanism mediated through MOR.

We performed 1st day Tc-99m-sestamibi gated SPECT with dipyridamole/rest T1-201 SPECT and 2nd day 24 hour delay T1-201 SPECT/rest Tc-99m-sestamibi gated SPECT in 27 patients with coronary artery disease(24) or having chest pain(3). Stress and rest Tc-99m-sestamibi gated SPECT was acquired at 60min post-injection. A 4-point scoring system(0 to 3 for normal to absent tracer uptake) for 17 segments was used. Wall motion was scored on another 4 point scale(0 to 3 for normal to dyskinesia) in the 1st day post-stress gated and the 2nd day rest gated SPECT. Post-stress gated SPECT showed wall motion abnormality in 94 segments(20%). Fifty-five segments among these 94 showed the same wall motion between post-stress and rest gated SPECT: i.e. 1-1 23 segments, 2-2: 29 segments, 3-3: 3 segments. Remaining 39 segments(41.5%) showed different wall motion between post- stress and rest Tc-99m-sestamibi gated SPECT. Twenty one segments with wall motion abnormality had normal perfusion(rest : 15 segments, 24 hour delay: 6 segments) at either rest or 24 hour delay. Fifteen among these 21 segments showed persistent post-stress and the 2nd day rest wall motion abnormality(persistent stunning). However, in 6 segments with pro-longed (1 hour after stress) stunning, abnormal wall motion did improve in the 2nd day rest Tc-99m-sestamibi gated SPECT(transient prolonged stunning). These 6 segments had normal perfusion at rest(n=4) or at 24 hour delay(n=2). Post stress wall motions showed significantly higher scores in persistent stunning than in prolonged transient stunning(P value<0.05). It was concluded that we could find stunned myocardium with gated Tc-99m-sestamibi SPECT at either post-stress or rest and that some myocardial walls of post-stress 1 hour gated SPECT did not show truly rest wall motion. So, we should be cautious if we use post-stress Tc-99m-sestamibi wall motion to assess rest wall motion.

Purpose: The purpose of this study was to examine the effects of bed angles and bed rest time combined with hemostatic methods on discomfort and hemorrhagic complications in patients after transfemoral cerebral angiography. Methods: Data were collected from 93 inpatients following transfemoral cerebral angiography, from April 20 to September 23, 2016. Patients were grouped according to bed angle ($0^{\circ}$ vs. $30^{\circ}$) and bed rest time combined with hemostatic methods (4-hour bed rest after manual compression vs. 2-hour bed rest after applying vascular closure device). Results: There was a significant group differences on discomfort (F=46.44, p<.001). The post-hoc analysis showed the lowest score of discomfort in those with bed angle $30^{\circ}$ and 2-hour bed rest. There was no difference in hemorrhagic complications among 4 groups. Conclusion: The postangiograpy discomfort can be effectively reduced with the least hemorrhagic complications by bed angle $30^{\circ}$ elevation and 2-hour bed rest after applying vascular closure device for those underwent transfemoral cerebral angiography.
