Filtration efficiency tests were conducted on a fiberglass mat filter with DOP aerosol having a diameter from 0.l${\mu}{\textrm}{m}$ to 0.45${\mu}{\textrm}{m}$ in the face velocity range of 1cm/sec to 10cm/sec. Filtration of submicron particles by a fibrous filter is characterized by a face velocity. The size of DOP aerosol which has a minimum removal efficiency decreases with increasing the velocity. A numerical solution of the diffusion equation is obtained for a fiberglass mat filter by using "Kuwabara's cell model" for the flow field and Von Mises Transformation for the actual flow around a fiberglass. The present theoretical results agree quite well with the experimentals for fiberglass mat. This result could be contributed to predict the removal efficiency on an air filter and to optimize the operating condition of an air purification system with a filter. a filter.

Objectives: Using as a sleep evaluation tool the Pittsburgh Sleep Quality Index (PSQI), this paper studied the effects of earthing on the amount and quality of sleep by examining a patient population of people who used and did not use earthing mats and a group of general healthy people. Methods: From September to November 2019, 30 patients who voluntarily used an earthing mat, 40 patients who did not use an earthing mat, and 40 healthy people who did not use an earthing mat were selected. A questionnaire applying the PSQI (Pittsburgh Sleep Quality Index) after being translated into Korean was distributed starting November 29, 2019 to 110 subjects. Out of them, 101 subjects who completed the questionnaire were examined. All statistics used SPSS 25.0. Results: The first overall score showed that all three groups had problems sleeping, with five points or more, but the general population had better sleep quality than the patient group. It also showed that the using matgroup had better quality of sleep than the ones that did not use the earthing mat In addition, the analysis of the third group through the variance analysis showed significance at >0.05 for the general population and the patient group. Based on this, a multi-comparison analysis of the third group showed significantly less than 0.05 in patients who do not use an earthing mat compared to the public. First of all, there are no statistically significant differences between the three groups in subjective sleep quality, sleep latency, and sleep time, but an analysis of multiple comparison analysis with the general population group showed that the quality of sleep was worse compared to those that used the mat. In addition, sleep efficiency, sleep disorder, sleeping pills, and daytime dysfunction were found to be less than >0.05 in the three groups. Conclusions: These results suggest that if you ground your body to Earth during sleep, the secretion of cortisol will decrease night levels, sync more with the natural 24-hour circulation rhythm profile, and that when you sleep, sleep is better and pain and stress are associated with the study. While the preceding study cannot confirm that contact with the ground affects the quality of sleep, it suggests that it is relevant as shown in this paper.

PURPOSE: This study examined the effects of applying mat Pilates and kinesio taping on the craniovertebral angle and muscle activity of adults in their 20s with a forward head posture. METHODS: The subjects were 20 adults in their 20s with a forward head posture: 10 from the Mat Pilates group (MPG) and 10 from the Kinesio taping group (KTG). Each group received the intervention for four weeks. The craniovertebral angle and muscle activity were measured before and after the intervention. Statistical analysis of this study was performed using SPSS Ver. 23.0 for Windows was used, and the statistical significance level was set to α = .05. RESULTS: The change in the craniovertebral angle within each group was decreased significantly after the intervention for both MPG and KTG (p < .05), but there was no significant difference in the comparison result of the difference in the amount of change between each group (p > .05). The change in muscle activity within each group did not show any significant change before and after the intervention in all the MPG and KTG muscles (p > .05), and there was no significant difference in all variables for the difference in the amount of change between each group (p > .05). CONCLUSION: Mat Pilates effectively reduced the CVA, but neither intervention significantly affected muscle activity.

Polygonatum is a genus placed in the family Liliaceae, distributed throughout the Northern Hemisphere and 16 of the species are grown naturally in Korea. In oriental medicine, the rhizomes of Polygonatum have been used as two different medicines, Okjuk (Polygonati odorati Rhizoma) and Hwangjeong (Polygonati Rhizoma). However, it is difficult to identify the morphological and chemical differences between the medicinal groups and thus easy to confuse the one with the other. Therefore, a clear classification standard needs to be established so as to be able to discriminate between them. In the study, the morphological characteristics of the plants, Polygonatum spp., were examined. Then, the differences in SNPs among the DNA sequences of 7 of the Polygonatum spp. and 1 of the Disporum spp. were analyzed by DNA barcoding with rpoC1, rpoB2, matK, and psbA-trnH of the cpDNA region. In the results, three regions, rpoC1, rpoB2, and matK were useful for discriminating the species, P. stenophyllum and P. sibiricum. Furthermore, it was possible to discriminate the individual germplasm within the species by using the combination of the results obtained from rpoB2, rpoC1, and matK.

Recently, NiO films have been studied as a buffer layer to fabricate the superconductor with preferred orientation and as a diffusion barrier to prevent the reaction between superconductor and textured nickel substrate . We fabricated NiO films on textured Ni substrate by thermal oxidation with various variables of temperature, oxidation time, atmosphere, and cooling rate. We investigated the alignment of NiO films by XRD and pole figure and the microstructures by SEM. (200) <001> alignment of NiO film was observed at the oxidation condition of $1200^{\circ}C$ far 10min and slow cooling in O2 atmosphere. During the process in Ar atmosphere, we could also observe the thermal faceting which affects the alignment of NiO alms on Ni substrate.

Generally, countermeasures for the train-induced vibration are divided into the measures at the source, propagation path and receiving object. Among these measures the countermeasure at the source location is the most active and effective one in the field of railroad. In this study, the effectiveness of each anti-vibration measures at the track(source location) such as elastic rail fastener, ballast mat were evaluated through the comparison of acceleration level, insertion loss at the installed locations of each measures. As result of field measurement of vibration at the railroad track supporting structures and on the ground nearby the structures, elastic rail fastener showed vibration reduction effect of 4.5 ∼7.3㏈ on the concrete slab, 1.6∼3.7㏈ on the ground with the train operation speed of 80km/hr. In the case of ballast mat, the vibration reduction effect at the concrete slab and on the ground were 11.9∼13.3㏈ and 6.1∼7.6㏈, respectively.
