The uniqueness of Bali is inseparable from its culture and religion. Embedded in the cultural environment, textiles become one of the most important aspects in Balinese life as it is used as a medium in sacred ceremonies. Balinese textiles are made and used under special conditions according to Hindu teaching. This paper aims to observe the aesthetics of Balinese sacred cloths that are seen in their techniques, colors, and patterns. Quantitative research included in this study is based on 261 images taken from literature review and Museums. Field research was done in eastern part of Bali. This paper has divided the era between ancient and modern times. The ancient era before the 20th century used textiles for religious purposes. Modern era started from the colonialization period by the Dutch in Bali during 1910-1942 added economic values to the textiles. The independence of Indonesia in 1945 created Balinese textiles as a unifying value as one of the identity of Indonesia. The techniques are classified as Weft Ikat, Double Ikat, weave with Supplementary Weft, and Prada. The colors of the ancient era are 'fixed' with the restriction of the colors red, black, and white. The colors of modern era are 'festive' with combination of yellow, green, blue, and purple. The characteristics of patterns are geometric, natural, human, and animal groups. Field research in this paper observes Klungkung Village that produces Endek and Songket cloths. The aesthetics of Endek cloth is 'royal statement' and Songket cloth is a 'cultural heritage.' Nusa Penida Island produces Cepuk cloths and is a 'protective guardian.' Satria sub-district produces Prada cloths and appears to be an 'opulence charm.' Lastly, Tenganan Village produces Geringsing cloth which possesses a 'legendary legacy.' To sum up, Balinese sacred cloth essence is a balance of tradition and modern.

With the increasing risk in building liquefied natural gas carriers (LNGC), pre-simulation of various scenarios is required for system integration and safe operation. In particular, the power management system (PMS) is an important part of the LNGC; it works in tight integration with the power control systems to achieve the desired performance and safety. To verify and improve unpredicted errors, we implemented a simulation model of power generation and consumption for testing PMS based on software-in-the-loop (SIL) method. To control and verify the PMS, numeric and physical simulation modeling was undertaken utilizing MATLAB/Simulink. In addition, the simulation model was verified with a load sharing test scenario for a sea trial. This simulation allows shipbuilders to participate in new value-added markets such as commissioning, installation, operation, and maintenance.

In this study, oil palm biomass such as empty fruit bunch (EFP) and palm kernel shell (PKS) was used as raw materials for making pellets. EFB and PKS are valuable lignocellulosic biomass that can be used for various purposes. If EFB and PKS are used as alternative raw materials for making pellets instead of wood, wood could be saved for making pulps or other value-added products. In order to explore their combustion characteristics, EFB and PKS were analyzed using thermal gravimetric analyzer (TGA) with ultimate and proximate analyses. From the TGA results, thermal decomposition of EFB and PKS occurred in the range of 280 to $400^{\circ}C$ through devolatilization and combustion of fixed carbon. After $400^{\circ}C$, their combustion were stabilized with combustion of residual lignin and char. PKS contained more fixed carbons and less ash contents than EFB, which indicated that PKS could be more active in combustion than EFB.

The Japanese housing market has implemented management and operation systems of community service ahead of the Korean market. This paper examines case studies of Japanese community services by reviewing related studies, studying homepages, and conducting in-depth interviews with management staff. The goal of this study is to find marketing strategies and the proper management practices in preparation for the upcoming low-fertility and aging society. The results of this study are as follows: 1) After Japan's bubble economy burst in 1985, so called that incorporated various community facilities with life services were introduced to the Japanese housing market in order to cope with the diversifying family types and lifestyles. This new trend was also due in part to customers' increasing demands for convenient urban condominiums. 2) In Japan, many developers and construction companies have run the management of community service programs and created new business models in collaboration with other affiliated companies. However, many of these programs have been found even more successful and reliable when the facility management companies collaborate with local service providers instead of relying solely on affiliated companies. 3) The early stage of life services began with "front-desk services", but these have evolved into more upgraded "concierge services" that can provide residents with tailored services and conveniences. Furthermore, some of the service providers have encouraged resident participation in the process of designing and implementing their community services. 4) In Korea, most construction companies and developers are still oriented toward providing hardware such as spaces and facilities in developing their community services. Therefore, companies with high market reputations must seek alternative ways to maintain and enhance their brand values by implementing new approaches in collaboration with both affiliated companies and local service providers. This can be done by finding new notions of managing and operating community services through research and development.

This study aimed to exploratorily investigate the new roles of libraries in the era of K-MOOC. For this, potential roles were derived and categorized from former researches and practices. And to evaluate the appropriacy of those roles, two expert surveys were conducted. Panel A was comprised of 30 professors who had been running K-MOOC classes and Panel B was comprised of 30 librarians of Universities that had adopted K-MOOC. The result shows that they both agree about distinct roles of library as information provider such as licensing and providing digital contents requested from information users, while technological part, for example, recording video and audio, managing website, and providing open access, was considered inappropriate because those roles were already taken by CTLs. Also, professors agree that information literacy education is required for teachers not just for students as the speed of technological development is too swift and librarians agree that they have to equipped with core competence in preparation for upcoming change by creating added value, establishing closer relationship with various educational and technological institutes, and securing organizational flexibility.

In an era where digital data takes on great importance, images are essential to various media. Noise is generated during the acquisition and transmission of such images, caused by a number of external factors. The removal of noise is an essential step in image processing. There are various methods used to remove noise, in accordance with the cause or form of the noise. AWGN is one of the leading methods. As such, this paper applies the edge detection method using the mean of each pixel after categorizing in detail the partial masks into nine areas as part of the preliminary process, in order to minimize noise that had been added to the image. In addition, the paper suggests an algorithm that applies different filters to the partial masks by using the critical mass value of the transfigured edge detection. To verify the competence of the suggested algorithm, it was compared with existing methods by using magnified images and PSNR(peak signal to noise ratio).

The small precision spindle motors in the high value-added products including the visible home appliances such as DLP projector require not only the energy conversion devices but also high efficiency, low vibration and sound operation. However, the spindle motors using the conventional ball bearing and sintered porous metal bearing have following problems, respectively: the vibration by the irregularity of balls and the short motor life cycle by the ball's abrasion and higher sound noises by dry contact between shaft and sleeve. In this paper, it is proposed that the spindle motor with a fluid dynamic bearing is suitable for the motor to drive the color wheel of the DLP(digital lightening processor) in the visible home appliances. The proposed spindle motor is composed of the fluid dynamic bearing with both the radial force and the thrust force. The fluid dynamic bearing is solved by the finite element analysis of the mechanical field with the Reynolds equations. The magnetic part of spindle motor, which is a type of Brushless DC Motor, is designed by the electro-magnetic field analysis coupled with the Maxwell equation. And the load capacity and the friction loss of fluid dynamic bearing are analyzed to bearing clearance variation by the fabrication error in designed motor. The design of the proposed motor is implemented by the load torque caused by the eccentricity and the unbalance of the fluid dynamic bearing when the motors are fabricated in error. The prototype of the motor with the fluid dynamic bearing is manufactured, and experiment results show the vibration, sound, and phase current at no load and color wheel load of the motors in comparison. The high performance characteristics with the low vibration, the low acoustic noise and the optimal mechanical structure are verified by the experimental results.

Plant industry is one of technology-intensive and most prosperous industries in Korea because of its recent prosperity and promising outlook in export. However, no Korean EPC company has yet been well prepared in lifting their capacity sufficient enough to get the upstream conceptual or basic design and engineering orders for sizable plant projects which are known as the more value-added. If systems engineering, a methodology which developed complex systems such as airplanes and has been justified its effectiveness in Defense and NASA projects, can be integrated with plant engineering which should be developed and applied based on the requirements of so many stakeholders, conditions, lifecycle concepts, and constraints of the projects, huge synergic effect is expected particularly in developing a specific upstream design, which is a conceptual or basic design. The notion of integration with each other between systems engineering and plant engineering can be really the crux of EPC's success in any plant projects. This paper suggests an approach showing a methodology how to dig out, analyze, evaluate, verify and implement the stakeholders' requirements into a plant design in conceptual phase using the theory and skills of systems engineering. ISO/IEC 15288 well known systems engineering standards is used. Carbon capture system is used for a case study, for it is an emerging technology in reducing emissions of carbon dioxide causing global warming from flue gas after combustion. Here systems engineering was proven to play a substantial role in enhancing the capability of designers in developing a conceptual design of whole plant or certain part of crucial plant systems.
