Jeonji technique was widely used in general Hanji handicraft including Jihwa handicraft. But the technique itself has not been passed on. By contrast, Jiseung technique and Jiho technique have been passed on and continuously developed. And although the Huji technique has not been transmitted, it should be vigorously used as a technique of producing the frame in order to revive the authenticity of traditional Hanji handicraft. Jumchi technique, a method of using water to connect between layers, is an effective technique of diversely expressing the feel of materials of Hanji craftworks. Modern Hanji handicraft has used the characteristics of paper and paperboard diversely produced nowadays as much as possible, which shows that it is more likely to develop as handicraft.

Ubiquitous tourism information systems are more and more required to provide cultural contents comprising material heritage, performing art, folk tradition, handicraft or customs of everyday life, along with traditional tourist information about hotel facilities and infrastructure. This study attempts to investigate the effect of tourists' hotel preference attributes in terms of their satisfaction with ubiquitous tourism service. In so doing, 145 questionnaires were used to analyze the satisfaction of u-tourism service and the hotel preference attributes through the field survey. The questionnaires were collected from hotel employees who had experienced the ubiquitous tourism service. It is found that some of hotel-preference attributes positively influence u-tourism satisfaction but not all of them did. Service and differentiation attributes had an impact to u-tour and u-hotel function. And beverage attributes, to u-tour function, and convenience attributes, to u-hotel function. These findings mean that the hotel built u-tourism infrastructure gain a competitive advantage than the otherwise hotel.

This paper introduces what the interactive projection technology is, and how to use this technology to make a musical instrument. There have been many art works and business products completed by the interactive projection technology, but this technology seldom has been used in the musical field, so we want to make a simple instrument by interactive projection technology, and expect more people to develop this field in the future.

This article reviews the art and practice of strategic management process in hospitals today, in order to help hospital administrators for managing strategic management system in their hospitals. The strategic management process model in this article is based on an integrated approach combining traditional environmental model with resource-based model of strategy. The components of the model are consisted of five steps: (1)formulating objectives, strategic assessment by external environmental analysis, internal capability analysis, TOWS analysis and marketing audit, (3)strategy choice considering context and criteria of choice, (4)program implementation through operational planning, resource allocation, and conversion, and (5)control by monitoring and evaluating hospital outputs. This article deals with many aspects of issues inherent in every step on this strategic management process.

In the future we are likely to see the development of public media with traditional media is out of the screen using a digital signage media facade. The purpose of searching for effective production and planning methods and message effects when planning messages the public can empathize with and accept. In this paper, we want to include the utilization of production techniques and media facade by applying culture and art and presenting how this can be applied to corporate advertising.

For two kinds of the multi-stage centrifugal pump with diffuser vanes and return channel vanes the meanline performance prediction is applied to get information of hydraulic performance at each internal flow station, because only flange-to-flange test curves are available. As a first step of redesign fur higher efficiency, the impeller geometry is numerically investigated in the present study. Quasi-3D inviscid loading distributions are obtained, for the two impellers, using the state-of-the-art method of impeller 3D design, which provides a guide to optimal redesign. Full 3D turbulent flow fields are thereafter analyzed, using the specialized CFD code, to confirm the redesign results. The inherent limitation of the traditional graphic method of impeller design, which most of domestic pump manufacturers are now employing, is found.

Puer tea is a traditional beverage originating from Yunnan area of China. We have analyzed 11 different commercial tea brands provided by Daboo Culture and Art Center. This study was carried out to evaluate the contents of polyphenols, antibacterial activity, antioxidantive ability and physiological activities of extracts from Puer tea. The electron donating ability was ranged from 57.26~99.16% and SOD-like activity was ranged from 1.4~10.4%. The inhibitory effect on the growth of cancer cell lines was examined by MIT assay. The Puer tea extract exhibited the greatest inhibitory effect at the concentration of 2% for all cancer cells tested.

In recent years, deep learning techniques have achieved tremendous successes in natural language processing, speech recognition and image processing. Collaborative filtering(CF) recommendation is one of widely used methods and has significant effects in implementing the new recommendation function, but it also has limitations in dealing with the problem of poor scalability, cold start and data sparsity, etc. Combining the traditional recommendation algorithm with the deep learning model has brought great opportunity for the construction of a new recommender system. In this paper, we propose a novel collaborative recommendation model based on auxiliary stacked denoising autoencoder(ASDAE), the model learns effective the preferences of users from auxiliary information. Firstly, we integrate auxiliary information with rating information. Then, we design a stacked denoising autoencoder based collaborative recommendation model to learn the preferences of users from auxiliary information and rating information. Finally, we conduct comprehensive experiments on three real datasets to compare our proposed model with state-of-the-art methods. Experimental results demonstrate that our proposed model is superior to other recommendation methods.

For a good design, it is important to understand consumers and trend of textile and fashion design. Previous researches on textile pattern design with CAD have been done. They have studied on Korean traditional floral motives/hand painting or some geometric patterns. Few studies have been done on conversational design. Therefore the purpose of study was to observe types of textile pattern design for the recent fiver years and determine fabric pattern trends, especially on the conversational motifs. The types of patterns were analysed with professional panels from the 2005～2009 collection sources, using SPSS program. This study was also develop textile patterns creating using CAD. We conducted design process on motif creating, repeat, and mapping jobs, using textile special design program Prima vision and Photoshop CS3.

This article introduces recent trends in RHC (Receding Horizon Control), also known as MPC (Model Predictive Control), that has been well recognized in industry and academy as a systematic approach for optimal design and constraint management. Constrained and robust RHCs will be briefly reviewed with milestone results. Among the diverse developments and achievements of RHCs, implementation issues will be focused on, together with the latest applications. In particular, this article introduces results on how to solve a finite horizon open-loop optimal control problem in an efficient way, together with code generation for real-time execution and easy implementation. Instead of traditional applications such as refineries and petrochemical plants, this article highlights some selected emerging applications, such as energy management systems and mechatronics, that have resulted from state-of-the-art high performance computing power and advanced numerical schemes.
