The perception volume, intake volume, and satiety rate of rice, soup, and side dishes using tableware and food trays were analyzed. Rice, beef, soup, and side dishes in tableware (1^st week) and the same menu in food trays (2^nd week) were served to twenty-nine female college students over two consecutive weeks (BMI 22.1 kg/㎡, Age 22.9 yr). The results showed that the perceived volume of soup served in tableware was significantly higher than when served in a food tray. On the other hand, except for the perception volume of soup (tableware: 174.80±19.40 g, food tray: 136.14±12.77 g, P<0.05), there was no significant difference in the food perception volume and food intake volume using tableware and food trays between the two groups. The satiety rate of the food tray group (6.68) was significantly higher than that of the tableware group (7.42) after one hour (P<0.05). However, except after one hour, the two groups' satiety rate showed a similar pattern. In most of the comparisons, the results showed no difference between table ware and food trays. Besides, the use of food trays has advantages in terms of easy to manage and convenience. Therefore, food trays might be a better option instead of a tableware.

Component based design is perceived as a key technology for developing advanced real-time systems in a both cost- and time effective manner. Already today, component based design is seen to increase software productivity, by reducing the amount of effort needed to update and maintain systems, by packaging solutions for re-use, and easing distribution. Nowdays, a thousand and one companies in If(Information Technology) industry such as Sl(System Integration) and software development companies, regardless of scale of their projects, has spent their time and endeavor on developing reusable business logic. The component software is the outcome of software developers effort on overcoming this problem; the component software is the way propositioned for quick and easy implementation of software. In addition, there has been lots of investment on researching and developing the software development methodology and leading If companies has released new standard technologies to help with component development. For instance, COM(Component Object Model) and DCOM(Distribute COM) technology of Microsoft and EJB(Enterprise Java Beans) technology of Sun Microsystems has turned up. Component-Based Development (CBD) has not redeemed its promises of reuse and flexibility. Reuse is inhibited due to problems such as component retrieval, architectural mismatch, and application specificness. Component-based systems are flexible in the sense that components can be replaced and fine-tuned, but only under the assumption that the software architecture remains stable during the system's lifetime. In this paper, It suggest that systems composed of components should be generated from functional and nonfunctional requirements rather than being composed out of existing or newly developed components. about implements and accomplishes the modeling for the Product Control component development by applying CCD(Contract-Collaboration Diagram), one of component development methodology, to MRP(Material Requirement Planning) System

Innovation can come from inside or outside organizations. Recently, organizations have begun turning to external knowledge more often, through various forms of collective intelligence (CI) as collaborative platform to solve complex problems. Several factors facilitate this CI utilization phenomenon. First, with the rapid development of Internet and social media, numerous web applications have become available to millions of the Internet users over the past few decades. Web 2.0 and social media have become innovative web applications that provide an environment for human social interaction and collaboration. Second, the diffusion of simple and easy-to-use technologies that enable users to interact and design web applications without programming skills have led to vast, previously unknown amounts of user-generated content. Finally, the Internet has enabled communities to connect and collaborate, creating a virtual world of CI. In this study, web enabled CI is defined as a composed ability of individuals who are acting as a single cognitive unit to achieve common goals, think reasonably, solve problems, make decisions, carry out complex tasks, and develop creative ideas collectively through participation and collaboration on the web. Although CI plays a critical role in organizational innovation and collaboration, the dubious quality of CI is still problem that is difficult to solve. In general, the quality level of content collected from the crowd is lower than that from professionals. Thus, it is important to identify determinants of CI quality and to analyze the relationship between CI quality and its usefulness. However, there is a lack of empirical study on the quality factors of web-enabled CI. There exist a variety of web enabled CI sites such as Threadless, iStockphoto or InnoCentive, Wikipedia, and Youtube. One of the most successful forms of web-enabled CI is the Wikipedia online encyclopedia, accessible all over the world. Another one example is Naver KnowledgeiN, a typical and popular CI site offering question and answer (Q&A) services. It is necessary to study whether or not different types of CI have a different effect on CI quality and its usefulness. Thus, the purpose of this paper is to answer to following research questions: ${\bullet}$ What determinants are important to CI quality? ${\bullet}$ What is the relationship between CI quality factors and the usefulness of web-enabled CI? ${\bullet}$ Does CI type have a moderating effect on the relationship between CI quality, its determinants, and CI usefulness? Online survey using Google Docs with email and Kakao Talk was conducted for collecting data from Wikipedia and Naver KnowledgeiN users. A totoal of 490 valid responses were collected, where users of Wikipedia were 220 while users of Naver KnowledgeiN were 270. Expertise of contributors, community size, and diversity of contributors were identified as core determinants of perceived CI quality. Perceived CI quality has significantly influenced perceived CI usefulness from a user's perspective. For improving CI quality, it is believed that organizations should ensure proper crowd size, facilitate CI contributors' diversity and attract as many expert contributors as possible. Hypotheses that CI type plays a role of moderator were partially supported. First, the relationship between expertise of contributors and perceived CI quality was different according to CI type. The expertise of contributors played a more important role in CI quality in the case of Q&A services such as Knowledge iN compared to wiki services such as Wikipedia. This implies that Q&A service requires more expertise and experiences in particular areas rather than the case of Wiki service to improve service quality. Second, the relationship between community size and perceived CI quality was different according to CI type. The community size has a greater effect on CI quality in case of Wiki service than that of Q&A service. The number of contributors in Wikipeda is important because Wiki is an encyclopedia service which is edited and revised repeatedly from many contributors while the answer given in Naver Knowledge iN can not be corrected by others. Finally, CI quality has a greater effect on its usefulness in case of Wiki service rather than Q&A service. In this paper, we suggested implications for practitioners and theorists. Organizations offering services based on collective intelligence try to improve expertise of contributeros, to increase the number of contributors, and to facilitate participation of various contributors.

Early detection of schedule delay in field construction activities is vital to project management. It provides the opportunity to initiate remedial actions and increases the chance of controlling such overruns or minimizing their impacts. This entails project managers to design, implement, and maintain a systematic approach for progress monitoring to promptly identify, process and communicate discrepancies between actual and as-planned performances as early as possible. Despite importance, systematic implementation of progress monitoring is challenging: (1) Current progress monitoring is time-consuming as it needs extensive as-planned and as-built data collection; (2) The excessive amount of work required to be performed may cause human-errors and reduce the quality of manually collected data and since only an approximate visual inspection is usually performed, makes the collected data subjective; (3) Existing methods of progress monitoring are also non-systematic and may also create a time-lag between the time progress is reported and the time progress is actually accomplished; (4) Progress reports are visually complex, and do not reflect spatial aspects of construction; and (5) Current reporting methods increase the time required to describe and explain progress in coordination meetings and in turn could delay the decision making process. In summary, with current methods, it may be not be easy to understand the progress situation clearly and quickly. To overcome such inefficiencies, this research focuses on exploring application of unsorted daily progress photograph logs - available on any construction site - as well as IFC-based 4D models for progress monitoring. Our approach is based on computing, from the images themselves, the photographer's locations and orientations, along with a sparse 3D geometric representation of the as-built scene using daily progress photographs and superimposition of the reconstructed scene over the as-planned 4D model. Within such an environment, progress photographs are registered in the virtual as-planned environment, allowing a large unstructured collection of daily construction images to be interactively explored. In addition, sparse reconstructed scenes superimposed over 4D models allow site images to be geo-registered with the as-planned components and consequently, a location-based image processing technique to be implemented and progress data to be extracted automatically. The result of progress comparison study between as-planned and as-built performances can subsequently be visualized in the D4AR - 4D Augmented Reality - environment using a traffic light metaphor. In such an environment, project participants would be able to: 1) use the 4D as-planned model as a baseline for progress monitoring, compare it to daily construction photographs and study workspace logistics; 2) interactively and remotely explore registered construction photographs in a 3D environment; 3) analyze registered images and quantify as-built progress; 4) measure discrepancies between as-planned and as-built performances; and 5) visually represent progress discrepancies through superimposition of 4D as-planned models over progress photographs, make control decisions and effectively communicate those with project participants. We present our preliminary results on two ongoing construction projects and discuss implementation, perceived benefits and future potential enhancement of this new technology in construction, in all fronts of automatic data collection, processing and communication.

Objectives: Based on individual and environmental characteristics of low-income children, we developed a nutrition education program for school-aged children from low-income families according to effective use in social welfare centers. Methods: We conducted in-depth group interviews to assess program needs in 28 participants, 10 low-income school-aged children and 9 of their care givers, 9 social workers and 9 care-givers. Theoretical backgrounds of our program were heath belief model and social cognitive theory considering motivation, action and environment characteristics. Results: Based on the findings of this qualitative study, we developed major program themes and contents. Five selected key themes were 'balanced diet', 'processed food', 'food hygiene and safety', 'Korean healthy traditional diet', and 'family cooking' to induce changes in dietary behaviors. Main findings of in-depth group interviews included 'child's active participation', 'simple and easy to understand messages', and 'environmental constraints' such as a lack of child care at home, limited budget of social welfare centers, and less qualified educators for nutrition and health. Each lesson was constructed as a 1-hour program particularly emphasizing activity-based programs, including cooking and teamwork exercises. Program contents in each session consisted of activities that could induce outcome and value expectations, self-efficacy, perceived benefits, and barriers and cues to actions regarding diet behavior. Conclusions: We developed a nutrition education programthat is rarely available for low-income children in Korea, considering theoretical bases. Further studies are needed to validate our program.

최근 과학기술혁신정책은 그 목표와 영역이 확대되면서 사회 환경 복지 노동 에너지 등 다른 정책 분야와의 결합이 활발해지고 있다. 특히 이명박 정부는 "저탄소 녹색성장"을 주요 국정 과제로 제시하면서 그동안 개별적으로 진행되어 온 과학기술, 환경, 사회, 자원 에너지 등 관련 정책간의 연계 통합이 핵심 과제가 되고 있다. 정책통합은 본질적으로 서로 다른 영역에서의 정책을 하나의 정책으로 묶어주는 것으로 정책의 본질적인 특성인 복잡성 시스템적 특성을 실제 정책과정에 반영하려는 노력이다. 또한 정책통합 과정에서 장기적인 비전의 공유를 강조함으로써 정부 전체의 효율성과 목표달성에 기여하도록 하는 것이다. 향후 우리나라가 나아가야 할 미래를 종합적으로 준비 설계해 나가기 위해서는 미래 예측 기능 강화와 더불어 장기적인 미래상을 바탕으로 현재를 끊임없이 준비해 나갈 필요가 있다. 특히 최근 과학기술혁신은 모든 사회변화의 기반이 되고 사회문제를 적극적으로 해결할 수 있는 핵심요소로 등장하면서, 각 부처가 소관정책에 투입하는 과학기술적 정책수단에 대해 관련 부처가 공유하고 종합적으로 검토하며 필요시 조정 통합될 수 있도록 하는 새로운 정책적 접근이 요구된다. 이와 함께 각 부처에서 각개약진 식으로 진행되고 있는 개별적이고 파편화된 정책 중 공통적 요소는 통합적인 전략으로 묶어 낼 수 있도록 하는 '정책통합'을 정책과정에 반영하거나 조직적 접근을 추가하는 경우 국가 전체적 정책효율은 제고될 수 있을 것이다. 이러한 접근은 영국 호주핀란드 등 선진국에서 최근 도입하는 통합형 정부형태에서도 볼 수 있고, 1990년대 이후 등장한 환경정책담론과도 유사하다. 우리나라의 정책결정 문화의 틀에서 부처할거주의와 수직적 의사결정의 문제점을 극복하고 과학기술적 접근의 비중을 높이며 정책효율을 제고하는 방법으로 정책통합의 방법을 제시하고 이에 필요한 정책과제를 제시하였다.

본 연구는 SNS 빅데이터를 활용하여 소비자들이 인지하는 무인계산대에 대한 사용자 경험을 분석하고자 한다. 이 연구를 위하여 네이버(NAVER)와 다음(Daum)에서 블로그, 뉴스, 지식인, 카페, 지식인(팁), 웹 문서를 대상으로 분석하였고 자료 검색을 위한 키워드는 '무인계산대'를 사용하였다. 자료 분석 기간을 2020년 1월1일부터 2021년 12월 31일까지 2년으로 선정하였다. 자료수집 및 분석을 위해서는 텍스톰(TEXTOM)을 통하여 빈도 및 매트릭스 데이터를 추출하였고 UCINET 6 프로그램의 NetDraw 기능을 이용해 네트워크 분석과 시각화 분석을 실시하였다. 그 결과 무인계산대는 소비자들의 경험요소 정의에 따라 접근성, 사용성, 지속사용의도, 기타로 군집화하였다. 공급자 측면에서 최저임금 인상과 근로시간 단축에 따른 문제를 해결하기 위해 무인계산대가 무분별하게 확산된다면 사회적 관점에서 더 큰 고용문제가 발생할 것이다. 아울러 무인계산에 익숙하지 않은 노인과 젊은 세대, 어린이, 외국인 등을 위해 쉽고 편리한 무인계산대 보급을 위한 제도화가 필요하다.
