교수학습 사이트는 교과 교육 지원이라는 특성상 그 서비스 개선에 있어서 사용자 중심적 디자인이 특히 요구된다. 기존 웹사이트 개선 연구는 단순히 웹사이트와 사용자 간의 인터랙션에서 발생하는 문제점에 초점을 맞추어 왔는데 사용자의 근본적인 니즈를 발견하고 만족시키기 위해서는 웹사이트 사용 정황의 이해라는 보다 확대된 개념에서의 접근이 필요하다. 따라서 본 연구에서는 웹사이트의 문제점 발견 및 사용자의 근본적 니즈 파악을 위하여 오프라인과 온라인 환경에 걸친 사용자 경험 관찰 프로세스를 기획하고 교수학습 사이트 서비스 개선을 위해 이를 적용하였다. 사이트 비지팅(Site Visiting), 비디오 에쓰노그라피(Video Ethnography), 사용자 다이어리 및 셀프카메라(User diary and Self camera), 그리고 인터뷰 기법이 현장 조사에서 이용되었으며 원격 사용성 평가 소프트웨어를 활용한 사용성 평가 및 카드소팅 테스트가 온라인 환경에서 진행되었다. 관찰 후 분석을 통해 교수학습 사이트의 새로운 컨텐츠 및 서비스 방향을 도출할 수 있었으며 웹사이트 사용자 경험 관찰 방법론 정립에의 가능성을 제시하였다.

Although population of the elderly is increasing rapidly, the older adults are the least users of the Internet in Korea. Prior research suggests that older adults are physically and psychologically disadvantaged when using the Internet. With the existence of the digital divide over different age groups, the objectives of this study were to identify the current status of Internet usage of Korean adults and to suggest some alternatives for solving digital divide on Internet usage. A total of 654 Korean adults, including the elderly, participated in both on-line and off-line (on-site interview) surveys using structured questionnaires. The results of statistical analyses indicated that the gap between the percentages of Internet users in younger and older groups was significantly wide, though many older adults had strong interests of Internet. To reduce this gap on digital divide, with an appropriate help from family and government, several characteristics of the elderly should be considered in designing some age-related web sites. Some effective alternatives suggested in this study may be used as basic data for universal design of Internet-oriented software.

The purpose of this study was to investigate the interaction effect of Web site menu designs and information structures on two information searching performances (searching and browsing) and three measures of users' attitudes (appeal, usability, and disorientation). Pronounced interaction effects occurred across four dependent variables except searching when decreasing and increasing information structure were combined with a simple selection menu and a pull-down menu. Further studies are needed to investigate additional interactions among factors of interface and information structure of Web sites.

Unmanned patrol robots are currently being developed for autonomous data survey in construction sites. As the amount of data acquired by robots increases, it is important to utilize proper metadata and system to manage data flow. In this study, we developed three materials, metadata design, robot system and web system, in the purpose of automating construction site data survey using unmanned patrol robots. The metadata was mainly designed to represent when and where raw data was acquired. To identify the location of data acquired, localization data from SLAM algorithm was converted to suit the construction drawings. The robot system and web system were developed to generate, store and parse the raw data and metadata automatically. The materials developed in this study was adopted to Boston Dynamics SPOT, a quadruped robot. Autonomous data survey of 360-picture and environment sensor was tested in two construction sites and the robot worked as intended. As a further study, development on the autonomous data survey to improve the convenience and productivity will be continued.

A new form of I-type PSC bridge girder, which has hole in the web, is proposed in this paper. Three different concepts were combined and implemented in the design. First of all, a girder was precast at a manufacturing plant as divided pieces and assembled at the construction site using post-tensioning method, and the construction period at the site will be reduced dramatically. In this way, the quality of concrete can be assured at the manufacturing factory and concrete curing can be well controlled, and the spliced girder segments can be moved to the construction site without a transportation problem. Secondly, a numerous number of holes was made in the web of the girder. This reduces the self-weight of the girder. But more important thing related to the holes is that about half of the total anchorages can be moved from the girder ends into individual holes. The magnitude of negative moment developed at girder ends will be reduced. Also, since the longitudinal compressive stresses are reduced at ends, thick end diaphragm is not necessary. Thirdly, Prestressing force was introduced into the member through multiple stages. This concept of multi-stage prestressing method overcomes the prestressing force limit restrained by the allowable stresses at each loading stage, and maximizes the magnitude of applicable prestressing force. It makes the girder longer and shallower. Two 50 meter long full scale girders were fabricated and tested. One of them was non-spliced, or monolithic girder, made as one piece from the beginning, and the other one was assembled using post-tensioning method from five pieces of segments. It was found from the result that monolithic and spliced girder show similar load-deflection relationships and crack patterns. Girders satisfied specific girder design specification in flexural strength, deflection, and live load deflection control limit. Both spliced and monolithic holed web post-tensioned girders can be used to achieve span lengths of more than 50m with the girder height of 2 m.

MIPROBE is a web-based tool for design of universal, genus-specific, and species-specific primers and probes. The main functions of MIPROBE are collection of target gene sequences, construction of consensus sequences, collection of candidate primers and probes, and evaluation of candidates by BLAST. Biologists with little computer skills can easily use MIPROBE to design large-scale universal, genus-, and species-specific primers and probes. This software is available at http://www.miprobe.com. Also detailed descriptions of how to use the program are found at this site.

The purpose of this study is to develop a on-line design tool for effectively coping with e-Business environment, or product design process into a Cyber model for traditional manufacturers which attempts new product development under such environment. It was finally developed as a model named $\ulcorner$Design Vortal Site; e-BVDS) that was based on the structure and style of internet web site. Results of the study can be described as follows ; \circled1 e-Business is based on the Internet. All processes in the context of e-Business require models whose structure and method of use are on-line styles. \circled2 In case that a traditional manufacturing business is converted into e-Business, it is better to first consider Hybrid Model that combines resources and advantages of both such traditional and digital businesses. \circled3 The product design process appropriate for e-Business environment has to have a structure and style that ensure utilization of the process as an Internet web site, active participation by product developers and interactive communication between participants in designing and designers. \circled4 $\ulcorner$e-BDVS) makes possible the use of designers around the wend like in-house designers, overcoming lack in creativity, ideas and human resources traditional business organizations face. However, the operation of $\ulcorner$e-BDVS$\lrcorner$ requires time and budget investments in securing related elements and conditions. \circled5 Cyber designers under $\ulcorner$e-BDVS$\lrcorner$ can easily perform all design projects in cyber space. But they have some limits in playing a role as designers and they have difficulty in getting rewards if such projects completed by them are not finally accepted. \circled6 $\ulcorner$e-BDVS) ensures the rapid use of a wide range of design information and data, reception of a variety of solutions and ideas and effective design development, all of which are not possible through traditional processes. However, this process may not be suitable to be used routine process or tool. \circled7 $\ulcorner$e-BDVS$\lrcorner$ makes it possible for out-sourcing or partners businesses to overcome restrictions in time and space and improve productivity and effectiveness. But such they may have to continue off-line works that can not be treated on-line.

While the cultural contents industry plays main role in global contents market recently, the market of Buddhist cultural property contents is still in insufficient state. Specially, despite most cultural properties is Buddhist cultural property in Korea, there is a lot of difficult problems in preserving, restoring and designing its prototype as cultural property. So, this research intends to contribute to the development of Buddhist design and Buddhist culture contents by developing the Pagoda Dharani contents using the Ten-storied Stone Pagoda on the Site of Wongaksa. The first thing is designing the Pagoda Dharani using the Ten-storied Stone Pagoda on the Site of Wongaksa. Also, using the Pagoda Dharani, we design and implement the Pagoda Dharani contents on the web. In this paper, by using the proposed the Pagoda Dharani contents, the previous activation problem of the Buddhist culture contents can be resolved.

Background Hypothenar free flaps (HTFFs) have been widely used for reconstructing palmar defects. Although previous anatomical and clinical studies of HTFF have been conducted, this technique still has some limitations. In this study, we describe some tips for large flap design that allows for easy harvesting of HTFFs with minimal donor site morbidity. Methods A total of 14 HTFF for hand defect reconstruction were recorded. The oblique flap was designed in the proximal HT area following relaxed skin tension line along the axis between fourth web space and 10 mm ulnar side of pisiform. A flap pedicle includes one or two perforators with ulnar digital artery and HT branch of basilic vein. In addition, innervated HTFF can be harvested with a branch of ulnar digital nerve. Electronic medical records were reviewed to obtain data on patients' information, operative details, and follow-up period. In addition, surgical outcome score was obtained from the patient, up to 10 points, at the last follow-up. Results Mean harvest time was 46 minutes, and two perforators were included in 10 cases. The mean flap area was 10.84 cm². There were no problems such as donor site depression, scar contracture, keloids, wound dehiscence, numbness or neuroma pain at donor sites, and hypersensitivity or cold intolerance at flap site, either functionally or aesthetically. Conclusion Palmar defect reconstruction is challenging for hand surgeons. However, large HTFF can be harvested without complications using the oblique axis HTFF technique. We believe our surgical tips increase utility of HTFF for palmar defect reconstruction.
