BACKGROUND/OBJECTIVES: Childhood obesity has become a global epidemic. Development of effective and sustainable programs to promote healthy behaviors from a young age is important. This study developed and tested an intervention program designed to promote healthy eating and physical activity among young children in South Korea by adaptation of the US National Aeronautics and Space Administration (NASA) Mission X (MX) Program. SUBJECTS/METHODS: The intervention program consisted of 4 weeks of fitness and 2 weeks of nutrition education. A sample of 104 subjects completed pre- and post- surveys on the Children's Nutrition Acknowledgement Test (NAT). Parents were asked for their children's characteristics and two 24-hour dietary records, the Nutrition Quotient (NQ) at baseline and a 6-week follow-up. Child weight status was assessed using Korean body mass index (BMI) percentiles. RESULTS: At baseline, 16.4% (boy: 15.4%; girl: 19.2%) of subjects were overweight or obese (based on $BMI{\geq}85%tile$). Fat consumption significantly decreased in normal BMI children ($48.6{\pm}16.8g$ at baseline to $41.9{\pm}18.1g$ after intervention, P < 0.05); total NQ score significantly increased from 66.4 to 67.9 (P < 0.05); total NAT score significantly improved in normal BMI children (74.3 at baseline to 81.9 after the program), children being underweight (from 71.0 to 77.0), and overweight children (77.1 at baseline vs. 88.2 after intervention, P < 0.001). CONCLUSIONS: The 6-week South Korean NASA MX project is feasible and shows favorable changes in eating behaviors and nutritional knowledge among young children.

과학기술의 발전과 더불어 현대전의 무기체계는 정밀 고도화되어 첨단기술을 필수적으로 요구한다. 이러한 복잡도가 높은 무기체계를 연구개발하는 방위산업 기업들은 협력을 통하여 다양하게 요구되는 지식정보에 대응하고 개발비용을 절감하고 위험을 분산시킨다. 본 논문은 방위산업분야에서 선제적으로 요구되는 협력과 기업에서의 혁신성과 및 내부 R&D역량과의 관계에 대한 실증연구를 수행하였다. 한국의 방위산업 관련기업 530개에 대한 협력관계를 조사하여 방위산업 제휴네트워크 분석을 수행하였다. 네트워크의 연결, 근접, 매개 중심성을 분석하고, 내부R&D역량에 따른 네트워크 중심성의 특성과 혁신성과의 관계를 구조방정식을 이용하여 네트워크 중심성의 간접효과를 분석하였다. 내부R&D역량이 높은 기업이 네트워크중심에 위치하나, 연결중심성이 높은 기업을 제외하고는 기업의 성과와는 무관하였으며 기업의 내부R&D역량은 혁신성과에 직접적인 영향을 미칠 뿐만 아니라 기업 간 협력을 매개로 혁신성과에 간접적으로도 영향을 미쳤다. 따라서 한국의 방위산업기업 중 내부R&D역량이 높은 기업은 네트워크내의 지식, 정보, 자원을 활용하는 것이 혁신성과에 더 유리한 것으로 분석된다. 이러한 연구결과는 방위산업 기업들이 혁신성과의 향상을 위해 내부R&D만에 의존하기보다 다양한 기관들과의 개방형 혁신활동에 주도적으로 참여할 수 있도록 정책 수립이 되어야 할 필요성을 제기한다.

The rapid development of internet technologies and social media over the last few years has generated a huge amount of unstructured text data, which contains a great deal of valuable information and issues. Therefore, text mining-extracting meaningful information from unstructured text data-has gained attention from many researchers in various fields. Topic analysis is a text mining application that is used to determine the main issues in a large volume of text documents. However, it is difficult to identify related issues or meaningful insights as the number of issues derived through topic analysis is too large. Furthermore, traditional issue-clustering methods can only be performed based on the co-occurrence frequency of issue keywords in many documents. Therefore, an association between issues that have a low co-occurrence frequency cannot be recognized using traditional issue-clustering methods, even if those issues are strongly related in other perspectives. Therefore, in this research, a methodology to reorganize social issues from a research and development (R&D) perspective using social network analysis is proposed. Using an R&D perspective lexicon, issues that consistently share the same R&D keywords can be further identified through social network analysis. In this study, the R&D keywords that are associated with a particular issue imply the key technology elements that are needed to solve a particular issue. Issue clustering can then be performed based on the analysis results. Furthermore, the relationship between issues that share the same R&D keywords can be reorganized more systematically, by grouping them into clusters according to the R&D perspective lexicon. We expect that our methodology will contribute to establishing efficient R&D investment policies at the national level by enhancing the reusability of R&D knowledge, based on issue clustering using the R&D perspective lexicon. In addition, business companies could also utilize the results by aligning the R&D with their business strategy plans, to help companies develop innovative products and new technologies that sustain innovative business models.

Agent-mediated electronic markets have been a grow-ing area of agent research and developmen tin recent year. There exist a lot of e-commerce sites on the In-ternet(e.g. Priceline, com, Amazon, com etc). These e-commerce site have proposed new business models for effective and efficient commerce activity. Intelli-gent agents have been studied very widely in the field of artificial intelligence, For purpose of this paper, an agent can act autonomously and collaboratively in a network environment on behalf of its users. It is hard for people to effectively and efficiently monitor, buy, and sell at multiple e-commerce sites. If we intro-duce agent technologies into e-commerce systems, we can expect to further enhance the intelligence of their support. In this paper, we propose a new coopera-tion mechanism among seller agents based on exchang-ing their goods in our agent-mediated electronic market system. G-Commerce. On G-Commerce, seller agents and buyer agents negotiate with each other. In our model, seller agents cooperatively negotiate in order to effectively sell goods in stock. Buyer agents coopera-tively form coalitions in order to buy goods based an discount proices. Seller agent's negotiation goods. Our current experiments show that exchanging mechanism enables seller agents to effectively sell goods in stock. Also, we present the Pareto optimality of our exchang-ing mechanism.
