Objective Nurse's dimission and attrition are globally considered as a public health issue. However, few studies have focused on the nurse shortage from the perspective of intent to stay, as previous studies have focused only on why they left. The purpose of this study was to conduct an integrative review of the factors connected with why nurses in China, Japan, and Korea stay in their current workplace. Methods The review was done using three databases namely CNKI, Wanfang, and Web of science. The relevant studies published by Chinese, Japanese, and Koreans from 2010 were also included in this review. Literature screening and data extraction were performed by the two researchers, and the qualitative research methods were used for analysis. Results A total of 17 studies were analyzed in this review and of these two were qualitative and 15 were quantitative. Three themes and six sub-themes emerged from the synthesization of the data of 17 studies, which will help us to find the factors for nurses’ intent to stay. The three aspects such as professional characteristics, nurses’ individual characteristics, and organizational factors are the main contributing factors of nurses’ intent to stay. Conclusions This integrated review has thrown some important factors about nurses’ intent to stay. It is increasingly clear that when (1) nurses have a good professional status, (2) nurses could enjoy a good working relationship, (3) the workplace could meet the needs of personal development, and (4) nurses have good organizational support and excellent leaders, they are inclined to stay in their current jobs. Managers need to adopt targeted measures to improve nurses’ intent to stay and to provide a practical reference for health care institutions and managers in different countries and areas to increase the retention rate of nurses and to alleviate the current situation of nurse shortage.

To reveal differences in the pattern of trabecular architecture in the epiphysis and metaphysis of the proximal tibia. The trabecular architecture of the proximal tibia was observed in 27 P45 plastinated knee specimens. In the medial and lateral condyles, under the articular cartilage surrounded by the medial or lateral meniscus, the cancellous bone is formed by thick and dense trabecular bands, which run longitudinally in the epiphysis and then pass through the epiphyseal line to terminate on the slanted cortex of the metaphysis. In the intercondylar eminence, the trabeculae are arranged basically in a network. In the central portion of the tibial metaphysis, cancellous bone consists of fine arcuate trabeculae, which extend to the anterior and posterior cortices, respectively. These trabeculae are intersected sparsely and form trusses over the medullary cavity. Near the areas of attachment of the iliotibial tract, tibial collateral ligament, anterior and posterior cruciate ligaments, and patellar ligament, the cancellous bone is locally reinforced with patchy trabeculae, dense radiating trabeculae, or two orthotropic trabecular bands. This study provides further accurate anatomical information on the trabeculae of the proximal tibia. The soft structures of knee joint, including the articular cartilage, menisci, and ligaments, and the slanted cortices of the metaphysis are important landmarks for the location of different arrangements of the cancellous architecture. The present results are beneficial for clinical diagnosis and treatment of pathologies of the knee joint, or the establishment of a finite element analysis model of the knee joint.

Background The fibula is only indirectly involved in the composition of the human knee joint and has therefore been neglected in the research on knee osteoarthritis. Nonuniform settlement of the proximal tibia plateau is clinically defined as when the height of the medial tibial plateau is lower than that of the lateral side in medial compartment knee osteoarthritis (KOA). The non-uniform settlement of the proximal tibia plateau may be caused by fibular support on the lateral side. Orthopedic surgeons practice partial fibulectomy based on the clinical manifestation of nonuniform settlement, and this technique has been shown to reduce pain and improve function in patients with medial compartment KOA. However, this hypothesis of the mechanism of nonuniform settlement lacks an anatomical basis. Methods The P45 polyester plastination technique was used to prepare sections of the proximal tibiofibular joint to investigate the distribution of the bone trabeculae in the region of the lateral tibial plateau. Results There was uneven distribution of trabeculae in the lateral condyle of the tibia and the head and neck of the fibula. The fibula and the posterolateral cortex of the shaft of the tibia united to form an arch beam via the tibiofibular joint. Many thick, dense trabeculae were present in a longitudinal direction above the tibiofibular arch. Conclusions The fibula supports the lateral tibial plateau, and the trabeculae were concentrated above the tibiofibular arch.

Study design A scanning electron microscopic study performed on three cadaveric specimens focused on the human suboccipital region, specifically, myodural bridge (MDB). Objective This study showed the connection form of the MDB among the suboccipital muscles, the posterior atlanto-occipital membrane (PAOM) and the spinal dura mater (SDM), and provided an ultrastructural morphological basis for the functional studies of the MDB. Summary of background data Since the myodural bridge was first discovered by Hack, researches on its morphology and functions had been progressing continuously. However, at present, research results about MDB were still limited to the gross anatomical and histological level. There was no research report showing the MDB's ultrastructural morphology and its ultrastructural connection forms between PAOM and SDM. Methods A scanning electron microscope (SEM) was used to observe the connection of myodural bridge fibers with PAOM and SDM in atlanto-occipital and atlanto-axial interspaces, and the connection forms were analyzed. Results Under the SEM, it was observed that there were clear direct connections between the suboccipital muscles and the PAOM and SDM in the atlanto-occipital and atlanto-axial spaces. These connections were myodural bridge. The fibers of the myodural bridge merged into the spinal dura mater and gradually became a superficial layer of the spinal dura mater. Conclusion MDB fibers merged into the SDM and became part of the SDM in the atlanto-occipital and atlanto-axial space. MDB could transfer tension and pulling force to the SDM effectively, during the contraction or relaxation of the suboccipital muscles. Level of evidence N/A.

Explain the existing device to avoid reeling cocoon sinking in automatic silk reeling machine, research the prevention of cocoon sinking automatically, and provide the integrated solution to keep cocoons in arrangement for reeling. In general, stop motion rod sends a signal when a minor fault occurs in each end, takes the initiative to prevent fault spread to knotty fault which causes a series of bad effects. Then coordinate with interlocked equilibrium, through end feeding cam to control separating plate, ensure the process safe in the most economical way for the industrial market demand. Operators need not handle the system manually while treating the faults, then removing hidden trouble and raising labor efficiency, so higher grade raw silk can be produced. This technique used can improve machine performances, it is the basis on which silk reeling machine should continue to develop.

In order to examine if the lead-in threaded devices can replace the traditional threaded devices in practical production, this paper primarily studies the structure and material of the lead-in threaded devices by analyzing its performance, the cleanness, mechanical properties and appearance of raw silk it produces, and by comparing it with traditional threaded devices. The experimental result shows that the lead-in threaded devices performance and the cleanness and mechanical properties and appearance shape of its raw silk are superior to the traditional threaded devices, it can completely replace the traditional threaded devices in process effects in actual production.

Background: There has been a lot of research on physical therapy for tension-type headaches. However, the efficacy of physical therapy on the suboccipital region remains unclear. Objective: To establish the effectiveness of physical therapy on the suboccipital area of patients with tension-type headache. Methods: Databases including Cochrane Library, Medline/Pubmed, CNKI, Embase, and Google Scholar were searched. After independent study selection by 2 authors, data were extracted and collected independently. On 1 hand, authors compared the treatment of the suboccipital area with control group. On the other hand, the efficacy of several physical therapy techniques on the suboccipital region was compared. The quality of the included studies was assessed using the Cochrane Handbook. RevMan 5.3 software was used for data analysis. The primary outcome measures were the cervical range of motion, the visual analog scale, and headache disability inventory. Results: Six randomized controlled trials with a total of 505 participants were included. Suboccipital soft-tissue inhibition technique (SIT) + occiput-atlas-axis global manipulation (OAA) was more effective than SIT in increasing craniocervical extension at 4 weeks post-treatment, the overall mean differences (MD) was 3.61, 95% confidence interval (CI) (0.89–6.34). There was no difference at 8 weeks post-treatment (MD 2.38, 95% CI −1.02 to 5.78, P = .17). SIT was more effective than SIT + OAA in increasing cervical flexion at 4-week post-treatment (MD −3.36, 95% CI −6.65 to −0.05). SIT + OAA was more effective than SIT on decreasing intensity of pain at 4-week post-treatment (MD −0.91, 95% CI −1.78 to −0.04), but no difference at 8-week (MD −0.43, 95% CI −1.18 to 0.33, P = .27). SIT + OAA was more effective than SIT in reducing the functional score of the headache disability inventory at 4-week post-treatment (MD −4.47, 95% CI −8.44 to −0.50). These results may indicate that the SIT + OAA combined therapy is more effective in short term (4-week), no major difference in longer term (8-week). Conclusion: Combined therapy may be more suitable for the treatment of tension-type headache.

Scaling exists commonly and its harm is huge. Because of this, design an amplitude-modulating electromagnetic field generator. The drive signal is obtained by amplitude modulation and power amplification. Generate two sine signals by the wien bridge and make the two signals through the MC1496 multiplier, the carrier’s amplitude changes with the modulator’s rule. And the frequency of carrier and modulator could be changed with the adjustment of the Oscillation resistance. Then, make use of D class amplifier TDA8920BTH to enlarge the power of modulated signal. At last, load the drive signal on a ferrite of magnetic coil to gain an electromagnetic field whose strength is modulated. Differ from the ordinary form of winding pipe with wire line, this design is making the magnetic coil close to a pipe. That’s more convenient for installing and removing. Of course, the concrete effect of descaling is needed to test by further experiments.

Indentations on the three main crystallographic planes (100), (110), and(111) of CaF2 were analyzed. Appropriate material parameters were obtained by experimental load-displacement curves. The results show a value in the range of 70–110 MPa for the initial shear yield strength. The submicron-level orthogonal cutting process of CaF2 had been investigated by the finite element approach, and the effects of tool rake angle on cutting stress and chip formation were investigated. The results indicate that increasing the tool rake angle causes a significant increase in stress and a decrease in chip thickness. The simulation results from the present study show the optimal tool rake angle to the ultra-precision cutting of CaF2 is -20°.

When femtosecond optical pulses propagate through the boundary of the vacuum and an electro-optic material, a transition radiation would be emitted, as well as Cerenkov radiation produced by the material. It has been found theoretically that the electric field of both kinds of radiation is an extremely fast transient and the peak of the radiation is in the far infrared.
