In this paper, we propose a user interface technique based on embedded sensors applying to apps in smart phone. Especially, we implement avata generation application using image filtering technique for photo image in smart phone. In the application, The embedded sensors are used as intuitive user interface to adjust the image filtering effect for making user satisfied effect in real time after the system produced the image filtering effect for avatar. This technique provides not a simple typed method of parameter values adjustment but a new intuitively emotional adjustment method in image filtering applications. The proposed technique can use sound values from embedded mike sensor for adjusting key values of sketch filter effect if the smart phone user produces sound. Similiarly the proposed technique can use coordinate values from embedded acceleration sensor for adjusting masking values of oil painting filter effect and use brightness values from embedded light sensor for adjusting masking values of sharp filter effect. Finally, we implement image filtering application and evaluate efficiency and effectiveness for the proposed technique.

모바일 어플리케이션 규모는 급성장하고 있으며, 이에 따라 모바일과 웹 서비스와의 결합도가 높은 어플리케이션들이 증가하고 있다. 이러한 모바일 어플리케이션의 증가는 가변성을 고려한 개발이 이루어져야 함을 의미한다. 현재 웹 서비스와 연동하는 모바일 어플리케이션을 변경할 경우 어플리케이션 전체를 재설치 해야 한다. 그러나 이러한 재설치는 결합도가 큰 어플리케이션인 경우 부작용이 발생할 가능성이 높다. 따라서 본 논문에서는 안드로이드 플랫폼 기반에서 웹 서비스와 연동 시 웹 서비스 프로토콜을 변경하기 위한 커스터마이제이션 기법을 제안한다. 프로토콜 커스터마이제이션 기법은 선택 기법과 플러그인 기법으로 구분한다.

소프트웨어 스트리밍은 사용자가 자신의 컴퓨터에 설치되어 있지 않고 서버에 있는 응용 프로그램을 스트리밍 받아 바로 사용할 수 있게 하는 가상화 기술이다. 이 기술을 이용하면 사용자는 응용 프로그램이 마치 로컬 컴퓨터에 설치된 것처럼 바로 사용할 수 있으며, 별도의 다운로드나 설치 과정을 요구하지 않는다. 소프트웨어 스트리밍은 네트워크를 기반으로 하기 때문에 제공되는 서비스는 네트워크 성능 및 상태에 영향을 받는다. 특히, 네트워크 고장이 발생하면 스트리밍이 더 이상 불가능하기 때문에 스트리밍 중인 응용 프로그램이 고장나거나 심한 경우 시스템 전체가 고장나게 된다. 파레토의 원리(Pareto Principle)에 의하면, 대부분의 사용자들은 자주 사용하는 몇 가지 기능을 주로 사용한다. 이러한 원리에 따라 네트워크 고장 감지와 지능적인 스트리밍 기술을 제공한다면, 네트워크 고장이 발생하더라도 사용자들은 이미 스트리밍된 응용 프로그램의 기능을 중단 없이 사용할 수 있을 것이다. 본 논문에서는 네트워크 고장이 발생하더라도 로컬 컴퓨터에 스트리밍된 기능을 사용자들이 지속적으로 사용 할 수 있게 하는 네트워크 고장감내 소프트웨어 스트리밍(에버그린)의 개념 및 기술을 제안한다. 또한, 에버그린 기술의 구현에 대한 자세한 내용에 대해 논의한다.

For more than two decades, the intracytoplasmic sperm injection (ICSI) technique has been used as a valuable tool to provide opportunities for studying fertilization, treating human infertility, and producing transgenic animals. Not only in facilitating fertilization but also in propagating mammalian species, ICSI has enhanced the potential of assisted reproductive technologies in human. Polyspermic fertilization has been one of major problems in pig reproduction, but the ICSI helped to solve the problem, and used widely to generate transgenic piglets. Although the ICSI technique is considered to be a very useful tool in assisted reproductive technologies, including generation of transgenic animals, there are some disadvantages using the technique. In this review, we describe the ICSI technique and its application in animal production and human infertility, and discuss advantage and disadvantage of the technique in mammals.

A large-scaled research project titled "Intelligent Excavating System (IES)" sponsored by Korean government has launched in 2006. An issue of real-time 3D terrain modeling has become a crucial point for successful implementation of IES due to many application limitations of state-of-the-art techniques developed in various high-technology fields. Many feasible technologies such as laser scanning, structured lighting and so on were widely reviewed by professionals and researchers for one year. Various efforts such as literature reviews, interviews, and indoor experiments make us select a structural light technique and stereo vision technique as appropriate techniques for accomplishment of real-time 3D terrain modeling. It, however, revealed that off-the-shelf products of structural light and stereo-vision technique had many technical problems which should be resolved for practical applications in IES. This study introduces diverse methods modifying off-the-shelf package of the structural light method, one of feasible techniques and eventually allowing this technique to be successfully utilized for achieving fundamental research goals. This study also presents many efforts to resolve practical difficulties of this technique considering basic characteristics of excavating operations and particular environment of construction sites. Findings showed in this study would be beneficial for other researchers to conduct new researches for application of vision techniques to construction fields by provision of detail issues about practical application and diverse practical methods as solutions overcoming these issues.

Purpose: The technique introduced in this study describes a technique for surface treatment that applies a photocuring resin to the surface of an interim crown fabricated by three-dimensional (3D) printing without a conventional polishing method. The purpose of this study was to evaluate marginal and internal fit and the intaglio surface trueness of interim crowns after surface treatment of 3D-printed crowns for clinical application. Materials and Methods: An interim crown was fabricated using a 3D printer with digital light-processing technology, and the surface support was removed. After the posttreatment process, the resin was thinly applied to the surface of the interim crown and polymerized to solve the esthetic problem of the surface without the conventional polishing process. In addition, the marginal and internal fits were measured to verify the clinical use of this technique, and the trueness was evaluated to confirm the deformation of the inner surface according to the technical application of the outer surface of the interim crown. The difference before and after the evaluation by a statistical method was verified using an independent t-test (α=0.05). Result: There was no significant difference in the marginal and internal fit before and after the application of this technique (P>0.05). There was no significant difference in intaglio surface trueness before and after the application of this technique (P=0.963). Conclusion: There was no change in the marginal and internal fit or in intaglio surface trueness of the interim crowns to which this technology was applied. This surface treatment technique is a more convenient method for interim crowns fabricated using 3D-printing technology without the conventional polishing process.

This paper explored the digital application of intangible cultural heritage from the perspective of cultural ecology. Through field investigations, combined with cultural ecology theory, an ontology-based semantic web technology was proposed, and Nanjing "Yunjin" brocade weaving technique was selected as the research object. The specific steps were as follows: First, based on the field surveys and cultural ecology theory, the intangible cultural ecological environment was divided into natural and social environments. Next, constructing the intangible cultural heritage ontology was constructed, including the collection and collation of Nanjing Yunjin weaving technique knowledge corpus, based on user needs analysis and corpus analysis, CIDOC CRM was used to create rules to build the ontology. Finally, based on the MediaWiki platform and Semantic MediaWiki, the semantic web model of the intangible cultural heritage was designed, and its semantic retrieval function was realized, thereby achieving the practical application of intangible cultural heritage digitization. Based on the perspective of cultural ecology, a set of intangible digital application models was proposed, which expanded the digital application of the cultural ecology theory, verified the application of this model in the sustainable development of cultural tourism, and provided reference for the sustainable development of cultural tourism.
