The applicability of cement grout （or cement-based grout） has been considered as an alternative to bentonite grout commonly used to backfill closed-loop vertical ground heat exchangers. In a geothermal heat pump system, repeated heating-cooling cycles may cause adverse effects on the integrity of cement grout in the ground heat exchanger. To account for the temperature cycling effect, the strength degradation of cement grout due to temperature cycling has been examined by measuring the unconfined compression strength of cured specimens in a humidity-temperature controlling chamber with applying temperature cycles between -5℃ and 50℃. There is a tendency that the unconfined compression strength decreases with an increase in the number of temperature cycles. On the other hand, an equivalent hydraulic conductivity of a pipe-embedded cement grout specimen was evaluated by carrying out a modified flexible wall permeameter test equipped with a water circulating system to control temperature inside the pipe section. The applied operating temperature range was from 5 to 35℃. After three cycles of heating-cooling circulation, the equivalent hydraulic conductivity becomes asymptotic to a constant value, which implies there is no severe detachment of the pipe from the cement grout.

Background Radial artery access for coronary procedures is a safe and beneficial technique. However, elderly patients have been considered as a higher risk group of access site related complications compared to younger patients. This study was conducted to investigate the feasibility and safety oftransradial coronary angiography or intervention in the elderly. Methods A total of 6132 patients from Korean Transradial Intervention Prospective Registry at 20 centers were analyzed. Patients were divided into the non-elderly group （n = 5667） and the elderly （_〉 80 years） group （n = 465）. Using propensity score matching, the elderly group （n = 465） was compared with one-to-one matched the non-elderly group （n = 465）. Results After propensity score matching, mean age was 64.3 ＋ 10.3 years in the non-elderly group and 83.5 -4- 3.3 years in the elderly group. There was no difference of procedural characteristics, procedural and fluoroscopic times. Access site cross-over rate was not different between the non-elderly group and elderly group （7.5% vs. 6.2%, P = 0.074）. Bleeding compli- cations occurred similarly in two groups （2.6% of the non-elderly group vs. 1.9% of the elderly group, P -~ 0.660）. Access site complications were 1.9% of the non-elderly group and 0.9% of the elderly group （P = 0.263）. Both of in hospital death and cardiovascular death for one year were also similar between two groups. Conclusions Transradial angiography or intervention was safe and feasible in elderly patients. Complication rates and clinical outcomes in elderly patients were comparable with those in non-elderly patients.

Air jet loom, as one of the shuttleless looms, transports a yam into warps using viscosity and kinetic energy of an air jet. Performance of this picking system depends on the ability of instantaneous inhalation/exhaust, configuration of nozzle, operation characteristics of a check valve, etc. In the recent past, many studies have been reported on the air jet discharged from a nozzle exit, but studies for understanding the flow field characteristics associated with shear layer and shock wave/boundary layer interaction in the nozzle were not conducted enough. In this paper, a computational study was performed to explain the flow field in the air jet nozzle with an acceleration tube and validated with previous experimental data available. The results obtained from the computational study show that, in the supersonic flow regime, the flow field depends significantly on the length of acceleration tube. As nozzle pressure ratio increases, drag force acting on the string also increases. For a longer acceleration tube, the total pressure loss is large, owing to the frictional loss.

In this paper, we suggest a controlled mutual quantum entity authentication protocol by which two users mutually certify each other on a quantum network using a sequence of Greenberger–Horne–Zeilinger（GHZ）-like states. Unlike existing unidirectional quantum entity authentication, our protocol enables mutual quantum entity authentication utilizing entanglement swapping; moreover, it allows the managing trusted center（TC） or trusted third party（TTP） to effectively control the certification of two users using the nature of the GHZ-like state. We will also analyze the security of the protocol and quantum channel.
