각종 정보원이 웹으로 제공되는 것이 보편화되어 있는 현실에서 웹자원은 단순한 정보제공 차원을 뛰어 넘어 실물 장서와 같이 체계적인 관리과 이용의 대상으로 인식되어야 한다. 웹기반 장서개발을 위해서는 표준화된 웹자원 평가요소의 확립이 시급한데, 웹자원 평가요소로는 일반적으로 권위성, 신뢰성, 내용의 성실성, 기능성, 연결성, 접근성, 구조 및 디자인, 링크사항, 이용자 지원 및 보호 등이 거론되고 있다. 그러나 효과적인 장서개발을 위해서는 웹자원의 유형별 특성을 감안하여 특정 평가요소를 강조하거나 포함하는 유연성이 필요하다. 또한 디지털 도서관의 웹자원 기반 장서개발 전략을 위해서 가치, 요구, 중복 방지, 지적 재산권, 지적 통제 평가기준은 면밀히 검토되어야 한다. 웹자원 평가의 객관성과 일관성을 위해 선정위원회를 조직하거나 웹환경 장서개발 모형을 개발하는 것, 다른 디지털 도서관과의 협력을 증진시켜 새로운 기준, 프로토콜, 마크업(markups), 메타데이터 등을 공유하게 하는 것, 이용자 중심의 장서개발을 위해 노력하는 것 등은 더 나은 웹자원 장서개발을 위한 또 다른 전략으로 제시되었다.

웹 서비스는 인터넷과 같이 공개적인 네트워크 및 관련 표준을 통하여 다수의 어플리케이션을 운영체제 및 프로그램 언어에 관계없이 상호 운영이 가능 하도록 해주는 표준화된 소프트웨어 기술로써 상호간의 필요한 서비스 발견, 제공 하여다양한 서비스를 가능하게 해주는 분산 컴퓨팅 서비스이다. 현재 웹 환경에서 사용되는 다양한 검색 방법은 서비스 성능에 기반하고 있어 새로운 서비스에 대한 서비스 선정에 문제점이 있다. 또한 웹 서비스의 성능을 기반으로 서비스 선정이 이루어져 서비스의 성능이 향상되거나 새로운 서비스가 발견되어도 기존의 서비스 순위에 밀려 계속적으로 서비스 선정이 이루어지지 못하는 기아현상이 발생한다. 따라서 본 논문에서는 서비스 선정에서 발생하는 기아현상을 해결하기 위해 확장 가능한 정보를 기반으로 서비스 성능의 향상이나 사용자가 원하는 정보를 획득하여 서비스 선정에 반영하여 웹 서비스 선정 시 발생하는 웹 서비스 기아현상을 해결하여 사용자에게 적합한 웹 서비스를 선정 할 수 있도록 한다.

현재 기존의 웹과 차별화를 의미하는 웹 2.0에 대한 관심이 높아져 가고 있다. 기존의 시스템이 클라이언트와 서버 모델에 기반을 둔 정적인 웹이 전형적이었다면, 웹 2.0은 웹이 근본적으로 변화하고 진화한다는 차원의 차세대 웹을 뜻한다. 본 논문에서는 웹 2.0규격하에서 쓰일 수 있는 RSS리더에 대한 모듈을 제안한다. 제안된 모듈은 Ajax를 이용하여 개발하였다 현재 쓰이는 RSS Feed가 브라우저에 따라 왜곡될 수 있는 부분을 보정하고 한글 및 제 3세계 언어의 인코딩 문제를 해결하였고, Ajax의 유동성 있는 프로그래밍을 통한 DragBox모듈과 RSS Feed의 자동 업데이트 모듈의 설계 및 개발을 통해 웹 2.0 기반상에서의 효과적인 콘텐츠의 활용을 위한 모듈을 개발하였다.

Buckling is one of the most critical phoneme in the design of steel structures. Lateral torsional buckling (LTB) is particularly significant for slender beams generally subjected to loading in plane. The web distortion effects on LTB are not addressed explicitly in standards for flexural design of steel I-section members. Hence, the present study is focused to predict the influence of the web distortion on the elastic (L_r) limiting lengths given in American Institute of Steel Construction (AISC) code for the lateral torsional buckling (LTB) behavior of steel beams due to no provision in the code for consideration of web distortion. For this aim, the W44x335 beam is adopted in the buckling analysis carried out by the ABAQUS finite element (FE) program since it is one of the most critical sections in terms of lateral torsional buckling (LTB). The strain results at mid-height of the web at mid-span of the beam are taken into account as the monitoring parameters. The web strain results are found to be relatively greater than the yield strain value when L/L_r is equal to 1.0. In other words, the ratio of L/L_r is estimated from the numerical analysis to be about 1.5 when the beam reaches its first yielding at mid-span of the beam at mid-height of the section. Due to the effect of web distortion, the elastic limiting length (L_r) from the numerical analysis is obtained to be considered as greater than the calculated length from the code formulation. It is suggested that the formulations of the limiting length proposed in the code can be corrected considering the influence of the web distortion. This correction can be a modification factor or a shape factor that reduces sectional slenderness for the LTB formulation in the code.

This study aims to investigate laws and standards(including technical guidelines) related to safety criteria for 22 kitchen machines frequently used in commercial kitchens. The study was based on literature survey, interviews with charge persons in kitchen machines manufacturing companies, cafeteria providing group meals and relevant association, and web surfing. The results showed that there are two types of safety criteria such as legally forced ones by laws and optional ones by national industrial standards or technical guidelines. High pressure safety control act, safety control and business of liquefied petroleum gas act and city gas business act prescribed gas use apparatus safety criteria, rational energy utilization act did those of pressure vessel such large rotary caldron, industrial health and safety act did those of food processing machinery, and electrical appliances safety control act did those of electrical kitchen appliances. Compulsory or optional standards or guidelines related to safety criteria for kitchen machines were presented by 22 kitchen machines. Safety devices shown in the laws, standards and guidelines were also summarized by kitchen machines and their risk factors.

IoT (Internet of Things) systems are based on heterogeneous hardware systems of different types of devices interconnected each other, ranging from miniaturized and low-power wireless sensor node to cloud servers. These IoT systems composed of heterogeneous hardware utilize data sets collected from a particular set of sensors or control designated actuators when needed using open APIs created through abstraction of devices' resources associated to service applications. However, previously existing IoT services have been usually developed based on vertical platforms, whose sharing and exchange of data is limited within each industry domain, for example, healthcare. Such problem is called 'data silo', and considered one of crucial issues to be solved for the success of establishing IoT ecosystems. Also, IoT services may need to dynamically organize their services according to the change of status of connected devices due to their mobility and dynamic network connectivity. We propose a way of dynamically composing IoT services under the concept of WoT (Web of Things) where heterogeneous devices across different industries are fully integrated into the Web. Our approach allows developers to create IoT services or mash them up in an efficient way using Web objects registered into multiple standardized horizontal IoT platforms where their resources are discoverable and accessible. A Web-based service composition tool is developed to evaluate the practical feasibility of our approach under real-world service development.

Backround : The paradigm of recent education has been shifting from existing style of professor-oriented, passive and rote teaching to learner-centered education. Rather than mere delivery of knowledge, today's idea of education uses various audiovisual media to let learners gain more problem-solving skills, judgment, cognitive thinking ability, and creativity to apply to real practice. Also, while current trends and change in policy ask for related industry to require practice-centered teaching learning model, Problem-Based Learning (PBL) is quite effective that it activates problem-solving skills as well as application of National Competency Standards (NCS). Purpose : The purpose of this study was to suggest a teaching learning model article as an approach to apply web-based PBL for patient & medical charge management practices. Discussion & Conclusion : This paper the cases on PBL and presents the teaching learning model on web-based PBL as an approach to applying web-based PBL, which fits Medical Information System Department that combines health-medical treatment and computer applications, to practical health administrative affairs.

Global e-SCM (electronic Supply Chain Management) has become an important business strategy in a rapidly changing global competition environment. It encompasses both domestic business and overseas business. Overseas business, including B2B and B2G, involves the complex trade procedures across countries. So, the standardization of electronic documents (messages) and business processes is one of critical factors for the successful implementation of global e-SCM. Without standardized messages and streamlined business processes, the benefits of global e-SCM would not be guaranteed because of human intervention like re-keying business data, which may create errors, delay processes, cause additional data or procedures, etc. Thus, this paper is to review the implementation challenges of Global e-SCM, to address the needs for electronic information flows through the standardization in electronic documents and business processes for fast and accurate trade transactions in the global supply chain activities, and to assert the importance of adoption of international standards.

Information technology has enabled mass standards calibration to be performed through internet. For this, an automatic weight handler was manufactured. During the operation the images of weight operation and the system are provided via the measurement system and a web server. The measurement system consists of a balance, a weight handler, instruments for environment measurement and a PC. The weight handler automatically loads and unloads weights on and from the weighing pan. The weight handler allows 6 series weights to be operated for weight calibration of 100-50-20-20-10-10 gram series weight. This capability could be used for "remote training" for series weight calibration.
