In this paper, we propose u-Learning management systems which are designed and implemented based on learning activities oriented components. The proposed systems are composed of components which can process the functionalities for coming into actions of learning activities. Specially, each component is broken into class units by which learning activities of users can be performed on various devices. When users by to connect the proposed learning management system, the system explores devices of users and the corresponding connection program, and then selects components that are fitted to the activities and combines them in a real-time. Our system provides u-Learning environment so that users can use the learning activity services taking no influence on time, place, various devices and programs. That is different from traditional e-Learning system which cannot support various devices of users directly.

Chronological changes of soil organic carbon (SOC) must be prepared by IPCC guidelines for national greenhouse gas inventories. IPCC suggested default reference SOC stocks for mineral soils and relative stock factors for different management activities where country own factors were not prepared. 3.4 million data were downloaded from agricultural soil information system and analyzed to get chronological changes of SOC for some counties and for land use in Korea. SOC content of orchard soil was higher than the other soils but chronological SOC changes of all land use had no tendency in differences with high standard deviation. SOC contents of counties depended on their own management activities and chronological SOC changes of districts also had no tendency in differences. Thus, Korea should survey the official records and relative stock factors on management activities such as land use, tillage and input of organic matter to calculate SOC stocks correctly. Otherwise, Korea should establish a model for predicting SOC by analyzing selected representative fields and by calculating SOC differences from comparing management activities of lands with those of representative fields.

In this paper, I investigate the impact of quality management activities on the public sector within the framework of Malcolm Baldrige (MB) national qualify model. The Structural Equation Modeling approach has been employed to investigate the cross influences among the seven MB categories. This empirical study shows that a number of statistical hypotheses are significant. The leadership category is the most important driver among the quality management activities. This, in turn, implies that the main source in quality management is to foster a solid qualify oriented leadership system. Categories such as Information Analysis, Strategic Planning, Human Resource Development and Management, and Process Management are significantly related to the Customer Satisfaction category. In addition, leadership, Information Analysis, and Customer Satisfaction categories ere significantly influential to Management Performance.

Purpose of this study is to draw policy implications for family resource management's strategies and leisure culture revitalization to Korean baby-boomers. This study review leisure activities characteristics of Korean baby-boomers and find their characteristics' impact on leisure economy. This research analyzed with raw data of "National Research Leisure Activities 2012" in different methods: analysis of frequency, multiple regression analysis, Correspondence Analysis, and etc. As a result, compared to all age groups in Korea, Korean baby-boomers current participation in leisure activities is low, but their expense on leisure is high. Their leisure activities are varied from different genders to their incomes. Especially, baby-boomers, who are on high income, participate in wasteful leisure activities and their consuming behavior will be the mainstream of Korean leisure economy, so economy, which is aiming for baby-boomers, will be invigorated when the economy is more concerned with use values toward time. Particularly, preparing for the retirement of baby-boomers, further researches based on integrated family policy should be considered plans and efforts on encouraging active volunteer works and participation in leisure culture revitalization of Korean baby-boomers.
