소비자가 선호하는 유통의 현대화를 위한 정부의 유통 현대화 정책에 따라 현대 시장이이 급속히 성장했다. 이에 반해 전통적인 시장은 작은 시장규모, 시장 내 복잡한 관계 및 부적절한 공간, 유통 구조, 비효율적인 운영 및 무질서한 거래 등으로 인해 소비자에게 인기를 잃고 있다. 따라서 본 연구에서는 유비쿼터스 컴퓨팅, 즉 컨텍스 트 인식 정보를 6W1H로 업그레이드하고 스마트 폰과의 인터페이스를 통해 시장을 활성화하고 증강 현실 기술을 통해 고급 정보를 제공하고자한다. 사용자 문맥을 이용한 상황인지 시스템의 구축은 지식 기반에 참조 규칙을 적 용하고 구현하는 방법에 따라 결과가 크게 다르게 나타난다. 이를 통해서 제안하는 방법은 RFID 기술과 6W1H 문맥 인식을 통해 전통 시장을 홍보하는데 목적을 가지고 있다. With the distribution modernization policy advanced by the government and consumers preference toward it, the so called "modern market" has undergone rapid growth. Conversely, traditional market is losing popularity with consumers as a result of inadequate modern structures, small market size, convoluted relationships, inefficient operation and disordered transactions, among others. Therefore, this study seeks to utilize ubiquitous computing, that is, the upgrade of context aware information to 6W1H and promote the market through the interface with Smartphone and provide advanced information through the augmented reality technology. For the construction of context-aware system using user context, the results may significantly differ according to how reference rules are applied to and implemented on knowledge base. In light of above, through the use of RFID technology and 6W1H context awareness, we seek to promote traditional markets.

Background: The level of urine cotinine is an indicator of tobacco smoke exposure. The purpose of this study is to investigate urine cotinine for the purpose of assessing the smoking status of Korean smokers and non-smokers exposed to tobacco smoke. Methods: The subjects were identified from the 2007-2009 and the 2010 data sets of the Korea National Health and Nutrition Examination Survey (KNHANES). They were assigned as non-smokers, current smokers and ex-smokers. Non-smokers were also divided into three subset groups according to the duration of smoke exposure. Each group was stratified by gender prior to analysis. Results: The median value of urine cotinine in the male current smokers was 1,221.93 ng/mL which was the highest among all groups, The difference between levels of urine cotinine for male and the female groups was statistically significant (p<0.01). In the female group, passive smoke exposure groups reported higher urine cotinine levels than non-exposure groups (p=0.01). The cutoff point for the discrimination of current smokers from non-smokers was 95.6 ng/mL in males and 96.8 ng/mL in females. The sensitivity and specificity were 95.2% and 97.1%, respectively, in males, 96.1% and 96.5% in females. However, the determination of urine cotinine level was not useful in distinguishing between passive smoke exposure groups and non-exposure groups. Conclusion: Urine cotinine concentration is a useful biomarker for discriminating non-smokers from current smokers. However, careful interpretation is necessary for assessing passive smoke exposure by urine cotinine concentration.
Design on SCADA Test-bed and Security Device

Most of the national critical key infrastructure, such as power, piped gas and water supply facilities, or the high-speed railroad, is run on the SCADA (Supervisory Control and Data Acquisition) system. Recently, concerns have been raised about the possibility of these facilities being attacked by cyber terrorists, hacking, or viruses. Thus, it is time to adopt the relevant security management techniques. This study analyzes the vulnerabilities of SCADA systems through scenarios, designs a test-bed to prove such vulnerabilities, and suggests security devices..
The Study of Copper Resource Management System and Process for Effectively Operation

In construction project management, ideologies and tasks related to resource supply are more significant than the integrated resources management. Such ideologies and tasks are considered crucial for achieving terms, pricing, quality and the goal of the project. It makes metal work resources even more important and as the target for special management. With these pressing issues in construction project management, the researchers proposed a web based system to improve such management task.
Mobile-based Security Agent for Provisioning Against DoS Attacks in Sensor Networking
Sungmo Jung,Donghyun Kim,Dae-Joon Hwang,Seoksoo Kim 중소기업융합학회 2015 중소기업융합학회 국제학술대회논문집 Vol.2 No.1
In this paper, a mobile-based security agent is presented which provide security mechanisms to security agents as well as hosts. This type of security agent is significant in providing security mechanism to security risks in cloud computing due to its ability to migrate from one host to another where it can resume its processing and service provisioning. Additionally, some of the current attacks are created that attackers may initiate. A fault tolerance at a high level is enabled for mobilebased distributed transaction processing in the cloud. The results show that we were able to detect and identify most of the attack messages and were able to identify the type of the attack within a specific period of time.
