It is possible to shorten developing process by making model using polyurethane foam in the area of automobile development process, etc. However, this skill is too difficult to be of practical use because machining is not easy due to characteristic of polyurethane foam. Domestic and foreign automobile company use clay, polyurethane foam. etc,, those are easy to handle and to make model after completing design sketch. But these materials is difficult to the machined and be worked by humans hand, There are so many difficult problem for machining by making model using polyurethane foam since cutting of elastic body like polyurethan foam has never been studied. Therefore, in this study, it is investigated to measured cutting force that is generated in case of polyurethane foam machining, and to make systematize tool compensation of polyurethane foam cutting work on automobile model by modification of tool offset method on existing steel.

The propagation of smart devices and the rapid expansion of wireless mobile networks have increased the need for ubiquitous device connectivity and contents access. DLNA is currently being used as the de facto standard for connectivity of consumer devices in the digital home. The guidelines provided by DLNA are intended to facilitate device and contents discovery, management, sharing and distribution. However, consumer experience with DLNA has been rather poor and usability not up to speed. Different problems and issues in limited compatibility have been reported due to manufacturer customizations. Such compatibility issues are often difficult to identify by average consumers who are not savvy in information communications and multimedia technology. In this paper, the design and implementation of a DLNA protocol inspection tool is presented for compatibility analysis among DLNA certified devices. The tool monitors the home network and performs analysis of the underlying protocols used by DLNA. The tool can be used for diagnostics and troubleshooting, enabling the user to identify compatibility issues between devices or problems in the network.

Purpose: This study aimed to investigate the perspective of consumers in healthcare services regarding patient safety. Methods: The study was a descriptive study using a self-reported questionnaire. The questionnaire was based on the Senior Empowerment and Advocacy in Patient Safety (SEAPS) questionnaire, which was designed to assess patient safety health beliefs. The survey was conducted online and a convenient sample of 302 adults participated in total. The reliability of the measurement (Cronbach's ${\alpha}$) was 0.758 in attitude (ATT), 0.546 in out-come efficacy (OE), 0.757 in self-efficacy (SE), and 0.703 in behaviors (BEH). Results: The average patient safety awareness score of the healthcare service consumers was 2.72 (ATT), 2.91 (OE), 2.87 (SE), and 2.27 (BEH). Our analysis indicated that there were no differences in ATT, BEH, or SE by gender, age, or education level. However, in OE and the total score of the four subscales, there were significant differences by age and gender. Correlations were identified between BEH and SE (r=0.409, p<.01), BEH and OE (r=0.202, p<.01), ATT and SE (r=0.358, p<.01), and OE and SE (r=0.241, p<.01). Conclusion: This study measured consumer perspectives concerning patient safety. The findings demonstrate the need for developing a measurement tool to assess consumer's perception of patient safety, considering Korean healthcare system and cultural context.

연구목적: 공사 중에 발생하는 화재는 빈도는 적으나 그 피해가 크다. 최근 물류유통산업의 성장으로 신축하는 물류창고의 공사장이 증가하고 있어 연구대상으로 선정하고 화재예방을 정량적으로 접근하기 위해 화재위험도 평가 Tool의 개발을 통해 공사현장의 재난을 줄이고자 연구를 진행하였다. 연구방법: 공정에서 진행되는 작업을 분류하여 연소의 3요소에서 제어가 어려운 공기(산소)를 제외한 가연물과 점화원을 등급별로 구분하고, 피난안전성을 추가로 대입하여 종합적인 화재위험평가 Tool을 객관적으로 정량화하여 정립하였다. 연구결과: 개발하여 제시한 화재위험도 평가 Tool을 이용하여 화재위험도가 낮은 굴착공사와, 화재위험도가 중간정도인 설비공사, 화재위험도가 높은 마감공사를 샘플링하여 결과값(CGI)을 도출하였다. 결론: 본 연구에서는 건설현장에서 화재발생 위험도를 평가할 수 있는 Tool의 개발로 위험도 평가에 따른 물적조건(가연물)과 에너지조건(점화원)을 제어하여 구체적인 예방대책의 수립과 피난안전성의 평가를 가능하게 하였다. 향후 건설현장의 화재위험도 평가Tool의 적용을 통해 위험을 줄일 수 있는 공정의 계획 수립과 소방설비의 적응성을 평가하는 기준으로 제공되길 기대한다.

The series hybrid propulsion system in bimodal tram consists of CNG engine, generator, inverter, motor and battery as main components. Among them, battery is very important thing to make a hybrid bimodal tram more efficient in driving. Battery pack is composed of 168 LPB(lithium polymer battery) cells, 650Vdc-300A. LPB should be treated with a good consideration in both temperature and overvoltage. This paper had analyzed and investigated the thermal flow and distribution of LPB module(l4 LPB cells) and Pack in simulated environments by commercial thermal analysis tool.

In this paper, a method to extract temperature effect information using the color temperatures of video scenes with mapping to temperature effects is proposed to author temperature effects of multiple sensorial media content automatically. An authoring tool to apply the proposed method is also introduced. The temperature effects generated by the proposed method are evaluated by a subjective test to measure the level of satisfaction. The mean opinion score results show that most of the test video sequences receive an average of approximately four points (in a five-point scale), indicating that test video sequences (with the temperature effects generated by the proposed method) enhance levels of satisfaction.

현재까지 실감 기술이 3-D 오디오나 비디오를 통하여 발전되어 왔지만, 단순히 시청각만을 통해서는 사용자에게 진정한 실감을 느끼도록 하기 힘들다. 사람은 오감을 통하여 모든 사물을 인지하므로 진정한 실감을 얻으려면 미디어를 통하여 인간의 다양한 감각을 모두 느낄 수 있도록 해 주어야 한다. 본 논문은 사용자 주변의 다양한 실감 디바이스들을 오디오, 비디오 콘텐츠와 동기를 맞추어 제어하므로 실감을 높일 수 있는 미디어 서비스 개념인 SMMD(Single Media Multiple Device) 미디어 시스템과 SMMD 미디어를 생성하기 위한 저작툴에 관하여 설명한다.

Spectroscopic ellipsometry (SE) has become an important tool in scatterometry based nano-structure 3D profiling. In this paper, we propose a novel 3D nano object recognition method by use of phase sensitive scatterometry. We claims that only phase sensitive scatterometry can provide a reasonable 3D nano-object recognition capability since phase data gives much higher sensitive 3D information than amplitude data. To show the validity of this approach, first we generate various $0^{th}$ order SE spectrum data ($\psi$ and ${\Delta}$) which can be calculated through rigorous coupled-wave analysis (RCWA) algorithm and then we calculate correlation values between a reference spectrum and an object spectrum which is varied for several different object 3D shape.

과거 소프트웨어 개발 업체들이 소프트웨어 위기를 겪었던 것과 유사하게 최근 인터넷 업체들은 웹 위기에 빠져들고 있으며 이러한 웹 위기에 대한 효과적인 해결 방안으로 최근 제시되고 있는 것이 웹 컨텐츠 관리이다. 그러나 기존의 웹 컨텐츠 관리 시스템은 컨텐츠의 생산과 배포에 초점을 두고 있는 반면 웹 컨텐츠 관리 프로세스의 지원 기능은 상대적으로 미약하다. 본 논문에서는 소프트웨어 개발 프로세스를 효율적으로 정의하고 실행할 수 있는 프로세스 중심 소프트웨어 공학 환경인 PRAiSE에 웹 컨텐츠 관리 기능을 통합한 프로세스 중심 웹 컨텐츠 관리 도구의 설계 결과를 보인다.

We demonstrate a high-spatial-resolution imaging and spectroscopy tool using a solid immersion lens (SIL), a hemispherical lens made of high refractive index glass (n ~2). Photoluminescence (PL) images of single CdSe nanocrystals confirm a numerical aperture enhancement factor of ~2, close to the refractive index of the SIL. In particular, a bare-eye observation of PL signals emitted by single nanocrystals with ${\sim}10\;{\mu}m^{-2}$ densities was possible over an ${\sim}30\;{\mu}m$ diameter region. In addition, the PL spectra of single CdSe nanocrystals were successfully measured at room temperature. Thus, this SIL microscope ensures a simple but powerful method for nanostructure spectroscopy.
