최근, 인터넷 쇼핑몰과 같은 웹 사이트를 대상으로 각 사용자에게 가장 필요한 정보를 제공하기 위한 웹 정보 추천 시스템에 대한 연구가 활발히 진행되고 있다. 사용자 프로파일과 명시적 피드백에 의존하는 대부분의 웹 정보 추천 시스템의 경우 사용자의 다양하고 정확한 정보를 필요로 하지만 실세계의 문제에 있어 이러한 연관 정보를 얻기란 쉽지 않다. 본 논문에서는 사용자의 명시적 피드백과 프로파일에 의존하지 않는 웹 정보 서비스를 위한 정보 예측 기법을 제안한다. 이를 위해 앙상블 Support Vector Machine과 하이브리드 SOM을 설계하고 적용하여 웹 로그 데이터의 희소성 문제를 해결하면서 대용량 웹 데이터로부터 사용자에게 꼭 필요하고 유용한 정보를 추천할 수 있는 동적 웹 정보 예측 시스템을 설계하고 구현한다.

In recent years, researchers are increasingly trying to use BIM-based 3D models for BIM nD design such as 4D (3D + Time) and 5D (4D + Cost). However, there are still many problems in efficiently using process management based on the BIM information created at each design stage. Therefore, this study proposes a method to automate 4D and 5D design support in each design stage by using BIM-based Dynamo algorithm. To do this, I implemented an algorithm that can automatically input the process information needed for 4D and 5D by using Revit's Add-in program, Dynamo. In order to support the 4D design, the algorithm was created to enable automatic process simulation by synchronizing process simulation information (Excel file) through the Navisworks program, BIM software. The algorithm was created to automatically enable process simulation. And to support the 5D design, the algorithm was developed to enable automatic extraction of the information needed for mass production from the BIM model by utilizing the dynamo algorithm. Therefore, in order to verify the 4D and 5D design support algorithms, we verified the applicability through consultation with related workers and experts. As a result, it has been demonstrated that it is possible to manage information about process information and to quickly extract information from design and design changes. In addition, BIM data can be used to manage and input the necessary process information in 4D and 5D, which is advantageous for shortening construction time and cost. This study will make it easy to improve design quality and manage design information, and will be the foundation for future building automation research.

Parasuraman, Zaithmal, 그리고 Berry에 의하여 개념화된 서비스의 결정 요인인 신뢰성, 반응성, 보장성, 공감성, 유형성의 차원이 WIS환경에서 적합한지 분석한 결과 측정척도로서 SERVQUAL을 사용할 경우 반응성과 보장성, 공감성과 유형성, 신뢰성의 3개 요인으로 사용되어 질 수 있으며, SERVPERF를 사용할 경우 5개 요인이 사용되어질 수 있었다. 품질결정요인 중 신뢰성과 유형성이 유의하게 서비스 품질에 영향을 미치는 것으로 나타났다. 컴퓨터 사용환경이 더욱 분산된 형태를 띠는 WIS환경에서는 사용자 지원서비스를 위하여 공식적 정보센터뿐만 아니라 비공식적 정보센터를 효율적으로 활용해야 할 것이다.

Objectives : This study aims to explore how social support and social network are related with health behavior. Methods : The target population was 12,449 people in Chungcheongbuk-do. The sample was accrued for the period of 3 months in 2008 by face to face interview of direct visiting from systematic sampling method. The instruments used in this study were social support, social network and health behavior. Results : There was significant difference in the level of social support and social network by sex, age, educational level, occupation, and monthly income(p<0.05). There was significant difference in the level of social support by alcohol drinking, physical exercise. There was significant difference in the level of social network by smoking, alcohol drinking, physical exercise, obesity(p<0.05). Multivarite analysis shows significant difference in the level of social instrumental support by smoking, physical exercise. It shows significant difference in the level of social emotional support by smoking. It also shows significant difference in the level of social network by smoking, physical exercise. Conclusion : These results suggest that social support and social network may be associated with health behavior. Because this study was cross sectional research, the order was not found between social support, social network and health behavior. Through a study on monitoring, we will obtain more information for relationship.

본 연구는 조직후원의 중요성에 대한 인식을 바탕으로 조직후원인식이 조직시민행동에 미치는 영향과 효과를 규명하는데 주목적을 두고 있다. 현대사회에서 제조업에 대한 인식과 함께 조직후원인식의 비중이 높아지고 있는데, 제조업 이외의 서비스 및 유통산업에서도 조직구성원에 대한 지원 및 복지에 대한 관심을 나타낸다면 조직의 후원을 지각하게 될수록 직무에 몰입을 유발하며, 조직과 동료를 위한 자발적인 헌신과 역할 외 행동인 조직시민행동을 더욱 보이게 되어 직접적인 성과를 드러낼 수 있을 것이다. 따라서 근로자들의 성과를 높이기 위해서는 구성원들을 더 많이 후원하고 도움을 제공하며, 근로자들에게 조직이 지원하고 있다는 사실을 적극적으로 인식시킬 필요가 있다. 본 연구의 결과는 조직후원인식은 성과를 강화할 수 있으며 이를 통해 조직구성원들의 조직시민행동을 유발할 수 있다는 것을 제시한다.

This paper describes the design and trial development of a system that supports continuous hazard mapping by local residents in their daily life. We performed an interview survey to design our system in a model traditional town in Saga Prefecture, Japan. The results show that despite continued efforts, many practical problems remain and residents feel unsafe. Considering these results, we designed and developed a unique information and communication technology-based support system that contributes to community-based disaster prevention and reduction. The continuous resident participation and posting design are the core concept for our community-based approach. Our system continues to support making a hazard map by integrating the community-based hazard information. Local residents register information (disaster types, risk level, photographs, comments, positional information) about locations that could be dangerous in a disaster. In addition, our system enables information sharing through a Web server. We expect that this information sharing will allow local hazard information for each district to be used.

With the rapid development of cloud computing, it raises real questions on privacy protection, which greatly limits the use of cloud computing. However, fully homomorphic encryption (FHE) can make cloud computing consistent with privacy. In this paper, we propose a simpler FHE scheme based on ring LWE problem, with a smaller size of ciphertext and a lower noise-expansion factor for homomorphic multiplication. Then based on our optimized RLWE-based FHE scheme, we propose a fast single-database private information retrieval protocol, combining with batching and number theoretic transform technology.

최근 이메일 서비스의 보완 수단으로서 RSS(Really Simple Syndication)를 이용한 정보 서비스가 활성화되고 있다. 과학기술 분야의 정보는 매우 방대하고 다양하며, 정보의 발생주기 및 서비스 또한 복잡한 특성을 가지고 있다. 단일 정보를 제공하는 기관인 경우 RSS를 이용한 정보 서비스는 정보를 제공하는 하나의 채널을 확보하는 의미에서 구현 시 고려해야 할 요소가 많지 않지만, 다양하고 방대하며 전문적인 과학기술정보의 특성을 반영한 RSS 서비스는 보다 정교한 설계와 구현을 필요로 한다. 본 연구에서는 RSS와 다른 정보배급 프로토콜을 비교하고, 국내외 RSS 동향조사를 수행하였으며, 과학기술정보의 특성을 고려한 RSS 기반 과학기술정보배급 시스템(STI-RSS)의 구현을 고찰하고 이의 활용방안을 제시하고자 한다.

The purpose of this study is to suggest the implications of social welfare workers' understanding of emotional labor and prevention of psychological exhaustion. In order to achieve this goal, I analyzed the effects of the levels of surface acting and deep acting, which are components of emotional labor in social welfare workers in social welfare center, on emotional exhaustion, depersonalization, and lack of sense of personal accomplishment which are components of psychological exhaustion. And I empirically analyzed how emotional labor affects psychological exhaustion, when superior support and fellow support as components of social support play a role as moderating variables. Empirical results show that emotional labor affects psychological exhaustion and social support plays a moderating role. Based on these results, theoretical and policy implications and future research directions are presented.
