Three-dimensional (3D) selfie services, one of the major 3D printing services, print 3D models of an individual's face via scanning. However, most of these services require expensive full-color supporting 3D printers. The high cost of such printers poses a challenge in launching a variety of 3D printing application services. This paper presents a stencil-based 3D facial relief creation method employing a low-cost RGBD sensor and a 3D printer. Stencil-based 3D facial relief is an artwork in which some parts are holes, similar to that in a stencil, and other parts stand out, as in a relief. The proposed method creates a new type of relief by combining the existing stencil techniques and relief techniques. As a result, the 3D printed product resembles a two-colored object rather than a one-colored object even when a monochrome 3D printer is used. Unlike existing personalization-based 3D printing services, the proposed method enables the printing and delivery of products to customers in a short period of time. Experimental results reveal that, compared to existing 3D selfie products printed by monochrome 3D printers, our products have a higher degree of similarity and are more profitable.

This paper presents the meter-out and meter-in speed control characteristics of a pneumatic cylinder with relief valve type cushion device. The piston displacement and velocity are measured to investigate high speed driving performance with variation of the pressure setting in relief valve, air supply pressure, load mass, the supply and exhaust flow rate from the cylinder. Also, the internal pressures and temperatures driving pressure and cushion chamber are measured. The piston displacements and velocities of meter-out and meter-in control are compared experimentally determined data. A comparison experimental data meter-out and meter-in control show that a relief valve type cushion device is suitable for high speed pneumatic cylinders. The desired response characteristics of piston displacement and velocity are satisfactory adjust the pressure setting of a relief valve with varying system parameters such as air supply pressure, load mass and controlled flow rate.

가정용 가스보일러의 안전장치인 새로운 과압방지밸브를 개발하였다. 본 과압방지밸브는 방출용량을 고려하여 입출구의 구경과 시트구경을 확대하였고, 스프링과 난방수가 닿지 않는 밀봉구조로 설계하여 기존 과압방지밸브의 문제점인 입구유로의 고착, 막힘이나 스프링의 부식현상을 최소화하였다. 개발된 과압방지밸브는 시험결과 분출개시압력, 분출정지압력, 밀폐성, 내구성의 성능특성이 우수하였고, 보일러 설치후의 작동성도 우수한 것으로 평가되었다. 본 연구결과를 통한 과압방지밸브의 표준화와 적용은 부품호환뿐만 아니라 유지보수가 용이하다는 장점을 제공할 수 있을 것이다.

This study was conducted to investigate the pain relief score and the degree of satisfaction among elderly people. This study has done from July 11th, 2001 to August 31st, 2001 at Hydrotherapy Facility in the College of Bogun(Taejon Health Sciences College) located in Taejeon, Korea. Eighty-eight patients were participated to the questionnaire. The results were as follow. 1. The mean value of the pain relief score in the female group was higher than the mean value of the pain relief score in the male group(p<0.05). The mean value of the pain relief score in the group having religion was higher than the group not having religion(p<0.05). The pain relief score was not significantly different in age, presence of spouse, the way of housing, and academic background. The degree of satisfaction was not significantly different in sex, age, presence of spouse, the way of housing, religion, and academic background. 2. The pain relief score and the degree of satisfaction were not significantly different in the presence of comorbidity, going with the hydrotherapy, and the moment of diagnosis. 3. According to the ADL, the mean value of the pain relief score in the Independent was higher than the mean value in maximal assistance and minimal assistance(p<0.05). Independent, maximal assistance and minimal assistance were not significantly different in the degree of satisfaction (p<0.05). 4. The pain relief score and the degree of satisfaction were not significantly different in the legion of pain.

Objectives: The purpose of this study was to analyze the current cases of oriental medical injury relief data from Korea Consumer Agency (KCA), and to report the current change of oriental medical disputes pattern. Methods: Oriental medical injury relief cases processed by KCA from January 2010 to February 2015 were collected and analyzed. Results: 149 Oriental medical injury relief cases from KCA were analyzed for the study. The highest number that had been relieved was 43 in 2014. In monthly status, 18 case in September was The highest. According to the record, the bigger city had the bigger amount of relief cases which was 53(Seoul), 43(Gyeng-gi), 11(Busan) and so on. In age categories, 30s had the highest number of injury relief cases. The injury relief cases of package program had been rapidly increasing since 2013. Cancellation was the dominant claims cause of package program and consumer required the refund of prepayment. Breast augmentation was the majority treatment type of injury relief cases of package program. Average prepayment of package program was \3,166,085. Conclusions: This study finded that the major cause of oriental medical dispute was changed from side effect of clinical treatment to patient's satisfaction of medical service.

The Buddhist cave temple carved into the rock provides a large space for the ritual in general in which a structure of Stupa is built in the center of the space purely for religious worship empty of Sarira, and the temple is formed around this Stupa. Relief-Stupa of the cave temple indicates the similar shape that of Relief-religious worship of flat land temple. However, there appears a small difference in representation since the background of formation of the cave temple differs in that of flat land temple. Specially, Caitya Stupa of currently existing cave temples have been damaged to lose of their original shape only possible to be analyzed the stylistic development through Relief-Stupa from which the characteristic of Stupa could be understood. The early cave temple could be characterized with a balanced structure consists of upturn bowl, steeple stone with simple drum & Hamikawasnagae, in which it appears strongly the detail factor characteristics of drum & steeple of having system with Caitya Stupa. In the post cave temple, the subject of worship moved to statue of Buddha due to the influence of Gandhara, Mathura art which reduced the importance of Stupa. This illustrates in Relief-stupa as well the style change as well as changes in detail factor. The sculpture appeared at the limited location either the wall of Caitya shrine or pillar in vihara cave with stronger decorative meaning. Contrast to the Relief Stupa of early flat land temples or the cave temples mentioned above sculptured with symbolism, however, the post cave temple showed the relief structure based on the plan of flat plan.

Growing concerns regarding air pollution have recently increased the demand for liquefied natural gas (LNG) fueled ships. LNG-fueled ships are equipped with an explosion relief valve in the crankcase to relieve excessive pressure and stop flames from emitting from the crankcase. In this study, a finite element analysis was conducted to evaluate the crankcase relief valve disk spring design using an ANSYS Workbench, v.15. The setting pressure, leak and explosion test performed by european standard EN14797 to evaluate function and mechanical integrity of crankcase relief valve. The tests results indicate that the pressure of the crankcase relief valve is 3.05 bar, with no air leakage at 2.97 bar. Finally, the mechanical integrity of the crankcase relief valve was confirmed through an explosion test in which the valve plate assembly, flame arrester, and other parts were safe from fracturing.
