Middle-aged women experience diverse psychological and physical stresses and tensions through the menopause, aging, and taking up too many social roles, which often leads to sleep disorder. But there are not many scientific researches on the issue. Therefore, the research of efficacy of singing bowl that helps relax middle-aged women who have sleep disorder is needed to improve their health. This study was conducted with Giorgi's phenomenological method with 4 middle-aged women with sleep disorder, whose Pittsburgh sleeping quality scale marked over 5 points, who took part in singing bowl experience for 40 minutes and did the interview. The study resulted in following conclusions that through participants' singing bowl experience, 518 constructive meanings, 15 meaning units, 7 sub components, and 2 group subjects were drawn up. Firstly, when participants took part in the singing bowl experience, they underwent physical, mental, imagery experiences which are physical pain and muscle relaxation, mental relaxation, and positive mindset and imaginary images and colors. Secondly, physical changes that the participants felt after singing bowl experience was increased physical relaxation, improved physical symptoms and more physical activities, and psychologically participants also felt reduced anxiety, increased happiness and positive mentality. And behavioral changes are relaxed movements, increased activities, and improved sleep is huge benefit through changes of sleep pattern. In this study, singing bowl is confirmed to be effective both physically and psychologically on relaxing the middle-aged women's tensions that are caused by sleep disorders and singing bowl experience is meaningful in that the middle-aged women as well as modern people with the sleep disorders can be helped to have better lives.
This paper examines how democracy is being taught in secondary school level of Indonesian civic education. For this purpose, this study analyses the textbook contents concerning democracy. First, this study sets the freedom, the right, the unity and the stability as key words and analyzes the characteristic of describing democracy by looking at how each keyword is explained in the textbook. The result of analysis shows that democracy of Indonesia can be described as "Pancasila democracy" and textbooks have tendency to relatively emphasize 'the unity', and 'the stability' by differentiating themselves from "liberal democracy" and "liberalism." The freedom in textbook can be interpreted in the context of organic-statism that state and interests of state have the ascendancy over individuals. This viewpoint is based on the historical contexts of Indonesia. However, when textbook describes about Indonesian democracy and its values, they deal with contents of democratic principles, "the freedom of opposition", "the negative freedom", and natural rights. And the study interprets the existence of the two contrasting concepts - relative emphasis on the unity of state and the statement about the importance of individual rights and the freedom - in the textbook as a logical tension in transitional process of traditional organic-statism. Second, the study examines educational contents in accordance with the method of description in textbook. It has been found that there are logical tension and fallacy in describing the principle of fundamental concepts and applicate that concepts into Indonesia case. Also, when describing Marsinah and Munir case, there are some parts distorted and overlooked the facts. On the other hand, the gaps between the explanation in textbook and reality can be pointed out. This study which examined textbook and contents of the rights of the individual is an introductory study on textbook, education and democracy for development of Indonesia and their education.

In this study, the effect of sosurfactant on microemulsion phase behavior was investigated in ternary systems containing alkyl ethoxylates nonionic surfactant, water and d-limonene. The addition of a cosurfactant produced a microemulsion phase over a wide range of temperature and promoted formation of a microemulsion phase at lower temperatures. In particular, small amounts of n-propanol, as a cosurfactant, were found to be the most effective in extending a microemulsion phase region over a wide range of temperature. Temperature sensitivity of a nonionic surfactant system was effectively relieved by addition of the anionic surfactant sodium dodecyl sulfate. And the formation of one phase microemulsion was not affected by pH, hardness concentration and addition of an antioxidation agent. The cleaner candidates were determined from microemulsion phase behavior study, and their cleaning efficiency was tested using a dipping method. All the cleaner candidates selected during this study showed excellent removal efficiency for abietic acid over a temperature range from 30 to $40^{\circ}C$ presumably due to a decrease in interfacial tension.
Flexural design of double composite box girder over the interior pier for three-span continuous bridge was performed by the LRFD method. The maximum span length of the continuous bridge ranged from 80m to 120m and the relative ratio of the span length was assumed to be 1:1.25:1. The girder section was designed for the strength limit state and service limit state with additional design check for constructibility. Before the bottom concrete and compression flange showed a complete composite action, the buckling of lower compression flange was checked. The flexural stiffness and flexural resistance characteristics for the section and for the constituent members such as tension flange, compression flange, and web were analyzed for different thicknesses of the bottom concrete on top of the compression flange. The effect of the distribution ratio of steel between the top and bottom flanges was investigated by analyzing ductility behavior and stress distribution through the girder's depth for several different relative area ratios of steel between the top and bottom flanges. It was found that a total amount of 15% of steel can be saved by applying the double composite system compared with that of the conventional composite system.
Purpose: There is no consensus regarding the relationship between the width of keratinized mucosa and the health of periimplant tissues, but clinicians prefer to provide enough keratinized mucosa around dental implants for long-term implant maintenance. An apically positioned flap during second stage implant surgery is the chosen method of widening the keratinized zone in simple procedures. However, the routine suture techniques used with this method tend to apply tension over the provisional abutments and decrease pre-existing keratinized mucosa. To overcome this shortcoming, a pre-fabricated implant-retained stent was designed to apply vertical pressure on the labial flap and stabilize it in a bucco-apical direction to create a wide keratinized mucous zone. Methods: During second stage implant surgery, an apically displaced, partial thickness flap with a lingualized incision was retracted. A pre-fabricated stent was clipped over the abutments after connecting to the provisional abutment. Vertical pressure was applied to displace the labial flap. No suture was required and the stent was removed after 10 days. Results: A clinically relevant amount of keratinized mucosa was achieved around the dental implants. Buccally displaced keratinized mucosa was firmly attached to the underlying periosteum. A slight shrinkage of the keratinized zone was noted after the healing period in one patient, but no discomfort during oral hygiene was reported. Clinically healthy gingiva with enough keratinized mucosa was achieved in both patients. Conclusions: The proposed technique is a simple and time-effective technique for preserving and providing keratinized tissue around dental implants.

This paper conducted research on identifying the process of change in fishing gear and organizing the function of periodically-used fishing gear types through net plan and computer simulation by selecting the design of the four types of fishing gear used for the Korea tuna purse seiner in the Western and Central Pacific Ocean, which 1,000 G/T class and whose length over all 60 m class. In the late 1980s, the length of the tuna purse gear was 1,939 m and the design depth was 160 m, but currently, the length and the design depth are 2,515 m and 230 m, respectively. As a result of the simulation, the expansion of the fishing gear increased buoyance, sinking force, sinking depth, surrounded area, and purse wire continuously. Recently, the maximum tension of the currently used purse wire of tuna purse seiner is 23.5 tons and is close to 25.4 tons which is the maximum lift capacity of WS454 winch. The way to improve fishing gear should be proceeded to increase sinking speed rather than expand the size of fishing gear.

Electric transmission towers are facilities to transport electrical power from a plant to an electrical substation. The towers are connected using power lines that are installed with a proper sag by loosening the cable to lower the tension and to secure the sufficient clearance from the ground or nearby objects. The power line sag may extend over the tolerance due to the weather such as strong winds, temperature changes, and a heavy snowfall. Therefore the periodical mapping of the power lines is required but the poor accessibility to the power lines limit the work because most power lines are placed at the mountain area. In addition, the manual mapping of the power lines is also time-consuming either using the terrestrial surveying or the aerial surveying. Therefore we utilized multiple overlapping images acquired from a low-cost drone to automatically reconstruct the power lines in the object space. Two overlapping images are selected for epipolar image resampling, followed by the line extraction for the resampled images and the redundant images. The extracted lines from the epipolar images are matched together and reconstructed for the power lines primitive that are noisy because of the multiple line matches. They are filtered using the extracted line information from the redundant images for final power lines points. The experiment result showed that the proposed method successfully generated parabolic curves of power lines by interpolating the power lines points though the line extraction and reconstruction were not complete in some part due to the lack of the image contrast.

Purpose: In order to maintain corrected nasal tip projection, strong support is important. Authors used calvarial bone graft method for this purpose. Patients were followed up about permanency of the bone graft for a long time. Methods: From 1995 to 1998, author performed calvarial bone graft on 30 adult patients with secondary cleft lip and nose deformity. Patients were observed for 34 months. There were no specific complications, and results were satisfactory. We could confirm the permanence of the calvarial bone graft in 3 patients by photography and radiologic studies for 10 years follow-up. Results: None of the patients showed size change or displacement. But the portion of graft facing the tip was absorbed resulting in loss of tip projection and short nose in two patients. One patient had fracture on the middle of the graft. This caused depression from lower portion of the dorsum to the tip. Conclusion: Despite of autogenous grafts such as calvarial bone, absorption of the bone may occur when compressed with tension for a long period. And the graft in the nasal tip not having any contact with the nasal bone may cause absorption of the graft.
Background : Kigong(氣功) is to develope a nature-therapy by controling and recovering Jinki(眞氣) and it has common features in Yangsaengbeob(養生法), Doinbeob(導引法) and Jeongkisin(精氣神), but it is rarely researched and applied in clinic examine. Objectives : it is compared and contrasted among Kukseondo(國仙道) Yeonjeongwon(硏精院), Seokmunhoheub(石門呼吸). Result : Kukseondo, Yeonjeongwon, Seokmunhoheub have the same point that beginners breath slowly, deeply and naturally. The breathing in each group becomes deeper gradually by mental and physical relaxation although each group has a different breathing method, and it is similar to Jogigyeol(調氣訣) in Dongeuibogam. Ywasik(臥式) is distinguished by the presence of sensation. The breathing in Kukseondo is Yidanhoheub(二段呼吸), the breathing in Yeonjeongwon is Yugi(留氣) and the breathing in Seokmunhoheub is that the ratio of inhaling and blowing are 6 to 4. The breathing in each group is deep and small, Ki also accumulates in the Below-abdomen between blowing and inhaling. This is confirmed by Sinjunapgi(腎主納氣) theory in Oriental-medicine. There is the breath, which is through skin, in Kigonghoheub(氣孔呼吸) of Samhabdanbeop(三合丹法) and Jolidanbeop(造理丹法) in Kukseondo, it is also in Gwiilbeop(歸一法) of Seokmunhoheub. In Kukseondo's case, the breathing is through skin mainly instead of a respiratory organ. In Seokmunhoheub's case, the circulation of Ki is through skin during breathing. In Oriental-medicine, this is called as Pyejupimo(肺主皮毛) which is connected with lung and skin. The breathing coincide with tension and relaxation of body while the breathing through skin and the absorption of Ki spread sensation over the whole body, but the breathing through skin is just a specific ability from a training.
Seismic-design procedures for walls require that the confinement in the critical (plastic hinge) regions should extend over a length in the compression zone of the cross section at the wall base where concrete strains in the Ultimate Limit State (ULS) exceed the limit of 0.0035. In a performance-based framework, confinement is linked to required curvature ductility so that the drift demand at the performance point of the structure for the design earthquake may be met. However, performance of flexural walls in the recent earthquakes in Chile (2010) and Christchurch (2011) indicates that the actual compression strains in the critical regions of many structural walls were higher than estimated, being responsible for several of the reported failures by toe crushing. In this study, the method of estimating the confined region and magnitude of compression strain demands in slender walls are revisited. The objective is to account for a newly identified kinematic interaction between the normal strains that arise in the compression zone, and the lumped rotations that occur at the other end of the wall base due to penetration of bar tension yielding into the supporting anchorage. Design charts estimating the amount of yield penetration in terms of the resulting lumped rotation at the wall base are used to quantify the increased demands for compression strain in the critical section. The estimated strain increase may exceed by more than 30% the base value estimated from the existing design expressions, which explains the frequently reported occurrence of toe crushing even in well confined slender walls under high drift demands. Example cases are included in the presentation to illustrate the behavioral parametric trends and implications in seismic design of walls.
