Purpose ; Iension-type headache is the most common headache. The effect of acupuncture for headache is already known, but the methods and technique of acupuncture is varied. Choice of acupuncture points is mostly relied on experience. Moreover, objective evaluation of acupuncture effects is lacking. Objective ; The objective of this study is to assess the difference of effects between dry needling on trigger point and dry needling on remote acupuncture point. The patients who were diagnosed as tension-type headache and administrated herb-medication were divided into two groups: Trigger point dry needling group and remote acupuncture point dry needling group, matching in sex, age. The degree of pain was measured by visual analogue scale(VAS) two times, before and after dry needling. Conclusion ; VAS showed significant decrement after dry needling on tension-type headache in both groups, but there was no statistically significant difference between two groups according to sex, age and duration. In addition, it is not statistically approved that there exists the difference of VAS between two groups about the treatment effects.

Objective: This study addresses a case of fibromyalgia with insomnia and dry mouth. Methods: A patient diagnosed with fibromyalgia was treated with Korean medicine including herbal therapy with Guibiondam-tang-gagam, acupuncture, pharmacopuncture, moxibustion, and chuna for 16 days. To evaluate the therapeutic effects, sleeping hours, time taken to fall asleep, and surprise on waking were assessed, and a numeric rating scale (NRS) was used to monitor dry mouth. Results: After treatment, the patient's sleeping hours increased, time taken to fall asleep decreased, and the patient woke up surprised less often. The NRS score for dry mouth also decreased. Conclusion: These results suggest that Korean medicine therapies with Guibiondam-tang-gagam have a beneficial effect on insomnia and dry mouth as additional symptoms of fibromyalgia.

We investigated the impact of NF₃ / H₂O remote plasma dry cleaning conditions on the SiO₂ etching rate at different preparation states during the fabrication of ultra-large-scale integration (ULSI) devices. This included consideration of factors like Si crystal orientation prior to oxidation and three-dimensional structures. The dry cleaning process were carried out varying the parameters of pressure, NF₃ flow rate, and H₂O flow rate. We found that the pressure had an effective role in controlling anisotropic etching when a thin SiO₂ layer was situated between Si₃N₄ and Si layers in a multilayer trench structure. Based on these observations, we would like to provide further guidelines for implementing the dry cleaning process in the fabrication of semiconductor devices having 3D structures.

The seismic response tests of a spent fuel dry storage cask model of 1/8 scale are performed for an typical 1940 Elcentro earthquake. This paper focuses on the seismic response test data generation to check the overturing possibility of a storage cask and the slipping displacement on concrete slab bed. A simplified cask model is used to take into account the variations in seismic load magnitude and cask/bed interface friction. The test results show that the model gives an overturning response for an extreme condition.

Erdosteine, an expectorant, has been known to show a very poor flowability. Furthermore, high dosing amount (300mg/cap) and bulk density make it more difficult to fill in a capsule less than No. 0 size as bulk state. We have studied the possibility of dry granulation process in purpose of getting a better flowability and manufacturing efficiency. A roller compactor was introduced for this purpose and the applicability of laboratory result into commercial scale instrument was also experimented.Roller compacting process was very favorable to obtain the granules with good flowability and improved density profiles.

A method for fabrication of nano-scale GaN structure by inductively coupled plasma etching is proposed, exploiting a thermal dewetting of Pt thin film as an etch mask. The nano-scale Pt metal islands were formed by the dewetting of 2-dimensional film on $SiO_2$ dielectric materials during rapid thermal annealing process. For the case of 30 nm thick Pt films, pattern formation and dewetting was initiated at temperatures greater $600^{\circ}C$. Controlling the annealing temperature and time as well as the thickness of the Pt metal film affected the size and density of Pt islands. The activation energy for the formation of Pt metal island was calculated to be 23.2 KJ/mole. The islands show good resistance to dry etching by a $CF_4$ based plasma for dielectric etching indicating that the metal islands produced by dewetting are suitable for use as an etch mask in the fabrication of nano-scale structures.

Enzymatic deinking of office-waste paper was studied using crude cellulase and papain-hydrolyzed cellulase from Trichoderma reesei Rut C-30 in small-scale and mid-scale. The results were compared with deinkings using commercial enzyme(Novozym 342) and conventional chemical methods. Maximum brightness and freeness were obtained at 3 units/g Oven Dry Paper(ODP) of CMCase activity using crude cellulase in mid-scale deinking experiments. The deinked pulp had higher physical strength and brightness, and lower freeness and yield than the pulp deinked in small scale. In small scale deinking, maximum brightness and freeness were obtained at 2 unit/g ODP. Deinking by papain-hydrolyzed cellulase showed similar results with one by Novozym 342. It was better in brightness and freeness, but showed lower physical strength and yield, than the conventional deinking by sodium hydroxide. The ratio of endo-1,4-glucanase and exo-1,4-glucanase components in papain hydrolyzed cellulase from T. reesei Rut C-30 was similar to that of commercial enzyme, Novozym 342, implicating a successful application as a deinking enzyme.

Objectives: The purpose of the study was to examine the influencing factors of self-reported dry mouth in the employees in social welfare facilities. Methods: A self-reported questionnaire was completed by 260 employees in social welfare facilities from January 5 to 30, 2015 by convenience sampling method. Except 25 incomplete answers, 215 data were analyzed by t test, one way ANOVA, Pearson's correlation coefficient analysis, and multiple linear regression analysis using SPSS 180. program. The questionnaire consisted of general characteristics of the subjects, health-related characteristics, whole body dryness and self-reported dry mouth. The oral health-related quality of life was measured by five point Likert scale, and a higher score indicated a lower quality of life. Results: The self-reported dry mouth in the employees in the social welfare facilities varied by the general health status, stress, oral health status and oral malodor. The self-reported dry mouth was closely related to the quality of life and the four subfactors including dryness of skin, eye, lip and nasal mucosa. The quality of life had the influence on the self-reported dry mouth, nasal mucosa dryness, eye dryness, and oral malodor in order. Conclusions: The self-reported dry mouth was closely related to whole body dryness and the quality of life. It is necessary to develop the quality of life improvement programs that prevent and manage the dry mouth and whole body dryness in the employees in the social welfare facilities.

The cuticle of spider's exoskeleton is a hydrophobic and non-adhesive material, but the jumping spiders have the distinctive attachment apparatus for adhesion on smooth dry surface without sticky fluids. We have examined the whole tarsal appendages of the jumping spider, Plexippus setipes with using scanning electron microscope to reveal the fine structural characteristics of the dry adhesion system. All eight legs have the scopulae with a pair of claws on the tip of feet. Each scopula is composed of two groups of setae that are capable of dry adhesion on smooth surface, and the hook structure of the claw is advanced to move on the rough surface. The setae toward the bottom of the tarsal segment are densely covered by numerous setules on the underside which broadened from middle to distal portion. It has been revealed by this research that the contact area of the setule is always a triangular shape, and these cuticular surfaces are connected by the elongated stalks from the underlying setae. It is likely that the nano-scale structures including a triangular depression and a longitudinal groove on each setule could functionate when the spider detach its feet from the substrate.
