본 연구는 인구사회적 특성, 음주, 스트레스 및 수면이 피부건강에 미치는 영향을 파악하기 위하여 415명을 대상으로 하였으며, 그 결과를 요약하면 다음과 같다. 1. 인구사회적 특성에 따른 피부건강상태는 건성 피부, 지성 피부에서 연령에 따른 유의 한 차이를 보였으며, 결혼상태는 기혼자가 미혼자보다 건성 피부의 점수가 유의하게 높았고, 지성 피부, 민감성 피부, 노화 피부는 통계적으로 유의한 차이가 없었다. 2. 음주자, AUDIT 점수 8점 이상인 문제음주자, 16점 이상인 알코올의존자, 및 CAGE가 1점 이상인 문제음주자에서 피부상태의 하위변수인 지성피부에서 유의하였으며, 민감성 피부는 문제음주자에서만 유의하였다. 3. 스트레스와 피부상태와 지각된 피부건강에 차이가 있는지를 분석한 결과 유의하지 않았다.

The legacy on-line translation service limits the participation to general users except clients and translators while the automatic translation service guarantees no exactness and perfectness on the translated results. This paper proposes a web-based translation service with business model that permits the participation of general users as well as translators and clients to modify and evaluate the transient contents of the translation ultimately leading to the collective intelligence.

Political and academic concerns on creative economy have been increased, despite of the debates on its concepts and socioeconomic implications. This article is an exploratory study about the mechanisms and the sources in which creative economy works. Due to ICT revolution and expansion of individual's networking competency, collective knowledge created by networking and city/region in which the collective knowledge has been embedded became the parts and parcels of creative economy. Three sources of creative city is as follows: regional peculiarity and locality from industrial clustering, intensity of urban networks(openness), and value orientations in regional problem solving.

애플(Apple)의 스마트폰(smart phon)은 우리의 여가생활을 바꿔놓았다. 개인과 개인, 혹은 개인과 단체, 단체와 단체의 커뮤니케이션의 방법에 있어 시 공간을 넘어 계층 간 장애 없이 글쓰기가 가능해졌다. 인터넷 가상현실에서 집단지성(swarm intelligence)의 활동이 늘어나고 있다. 집단지성들이 활동 가능한 확장된 교육프로그램이 논의 되어야 할 것이다. 문학관의 학교 교육의 시각적인 지도활용에 있어서 적극적인 도입이 필요하다. 또한 전국 5일제 시행 이후 체험환경은 교육, 관광 등 연계성을 들 수 있다.

The Internet is appearing a new paradigm called Web 2.0 which 'Participation', 'Sharing', 'Openness', 'Cooperation'. Web 2.0 is expanded by experts and general users and many people's ideas can solve more problems than an expert's idea. The collective intelligence is techniques that express the valuable of Web 2.0. For this reason, the collective intelligence has attracted attention because of its potential as an educational tool. The purpose of this study is to develop a PBL-based programming instruction model using collective intelligence to improve students' problem solving abilities and programming attitudes and verified its effectiveness. As a result, the developed instruction model showed significant differences in the students' problem solving abilities and programming attitudes. According to these results, these have been proved that a PBL-based programming instruction model using collective intelligence has an influence to the students' problem solving abilities and programming attitudes.

Folksonomy, which is collaborative classification created by freely selected keywords, is one of the driving factors of the web 2.0. Folksonomy has advantage of being built at low cost while its weakness is lack of hierarchical or systematic structure in comparison with taxonomy. If we can build classifier that is able to classify web resources from collective intelligence in taxonomy, we can build taxonomy at low cost. In this paper, targeting folksonomy in Slashdot.org, we define a general model and show that collective intelligence, which can build classifier, really exists in folksonomy using a stability value. We suggest method that builds SVM classifier using stability that is result from this collective intelligence. The experiment shows that our proposed method managed to build taxonomy from folksonomy with high accuracy.

Purpose : Numerous methods exist for diagnosing nonpalpable testis in treatment of cryptochidism. However, there is no clinically established data for the rational diagnostic tool of nonpalpable testis in terms of expenses. We tried to establish a current conventional diagnostic course of nonpalpable testis. We then evaluated the efficacy of ultrasonography, physical examination under general anesthesia and laparoscopy for diagnosing nonpalpable testis. Methods : Between March 2000 and February 2005, 103 boys(129 testes) with undescended testes were treated in our department. There were 31 testes(24.0%) that were not palpable at physical examination. These patients were evaluated with ultrasonography and repeated physical examination under general anesthesia. In the cases where testes could not be detected with ultrasonography and physical examination under general anesthesia, laparoscopy was performed to diagnose nonpalpable testis. Results : In 31 cases of nonpalpable testis, 13 testes were detected with ultrasonography and 15 testes became palpable with physical examination under general anesthesia. All of the remaining 16 nonpalpable testes were confirmed with laparoscopy. Conclusion : Physical examination under general anesthesia was superior to ultrasonography in making a diagnosis of nonpalpable testis. Ultrasonography and physical examination under general anesthesia could reduce the incidence of diagnostic laparoscopy. Therefore, it is recommended that ultrasonography, physical examination under general anesthesia and laparoscopy must be performed conventionally in order to diagnose nonpalpable testis.

최근 지식정보화 시대의 집단지성기반 교육 패러다임 변화는 큰 이슈로 떠오르고 있다. 특히 융합적 학문을 근원으로 창의성 계발과 아이디어를 중요시하고 있으며, 창조적 교육방식을 지향하고 있다. 그러나 다양한 영역에 지식전문가들과 학습자들 간에 지식을 공유하기 위한 플랫폼 공간이 제대로 제공되고 있지 못하며, 단순한 컨텐츠 제공을 목적으로 이러닝 서비스가 일부 제공되고 있는 것이 현실이다. 따라서 본 논문에서는 집단지성을 기반으로 지능형 튜터링 에이전트 시스템 설계를 제안하고, 새로운 에이전트(Agent) 개념을 통해 지식인들과 학습자들 간에 지식을 공유할 수 있을 뿐만 아니라 새로운 지식을 창출하고, 관리 및 유통할 수 있는 구조를 연구하였다. 또한 사용자들로부터 발생하는 데이터와 정보들을 자동 분석하여 지능적으로 학습상황에 대처할 수 있도록 설계하였으며, 튜터(Tutor)와 튜티(Tutee)간에 협력적인 학습 생태계가 형성될 수 있도록 하였다. 따라서 본 연구의 결과를 기반으로 미래 스마트 학습 플랫폼 발전에 많은 도움이 되길 기대한다.
