In this paper, we propose a level of contexts such as low level and high level contexts, and its criteria of categorization are the existence of interaction and composite process done by the inference mechanism. When there is no matching high level service for the associated high level context, this context is described as meaningless. If the services cannot be provided with the entities by the system, this situational information is of little consequence. To provide services with the entities, we propose "community computing" architectural concept which provide the high level service to a group of agents in a community, and can be managed by the service scenario

Purpose: This study was to determine the effects of calcium intake on bone mineral density (BMD) in pre and post menopause women and to provide basic data for enhancing bone health of middle aged women. Methods: A total of 700 middle-aged women living in Seoul and Geonggi Province were interviewed during the period from June 2003 through January 2004 to investigate their social. demographic and physiological characteristics, health and daily activity performance, and their dietary patterns, and bone mineral density was measured. The survey of dietary intake was 24 hour recalls, and the individual calcium intake was calculated using food frequency. Data of 618 subjects was used for the analysis. Of the calcium intake levels, BMD values of the subjects of 20% of high level. 60% of middle level and 20% of low level were analyzed and compared. Results: The level of calcium intake according to general characteristics of the subjects was significantly related to age (p=0.001), education levels (p=.003) and marital status (p=.001). The BMD of the lumbar vertebrae and femur of the subjects taking a high level of calcium showed significantly higher than that of the subjects taking a middle level and low level of calcium. Femoral T-score was also significantly higher in subjects taking a high level of calcium than that of those taking a middle level and lower levels of calcium. Lumber spine T-score was higher in the high level group than that of the middle level group. Conclusion: The study revealed that women taking a high level of calcium had better bone health. Therefore. calcium intake is extremely important in daily dietary intake so that the intake of calcium-rich foods is highly recommended.

As building information modeling (BIM) is expanding its influence in various fields of architecture, engineering, construction and facility management (AEC-FM) industry, BIM-based automated code compliance checking has become possible prospects. For the automated code compliance checking, requirements in building code need to be processed into explicit representation that enables automated reasoning. This paper aims to develop high-level methods that translate verb phrases into explicit representation. The high-level methods represent conditions, properties, and related actions of the building objects and clarify the core content of the constraints. The authors analyze building permit requirements in Korea Building Code and establish a standardized process of deriving the high-level methods. As a result, 60 kinds of the high-level methods were derived. In addition, method classification, analysis, and application are introduced. This study will contribute to the representation of explicit building code sentences and establishment of the automated building permit system of Korea.

This research was intended to furnish basic data which can be helpful to maintain and improve the skin health and to activate aromatherapy by analyzing the knowledge, attitude and behavior on the aromatherapy skin care of college students. As their grade got higher, students of beauty class showed the level of knowledge on aromatherapy higher than those of non-beauty class, and that of girl students was higher than that of boy students and as the living standard of students got higher, and pocket money of a month of them got more, the level of knowledge on aromatherapy of them was high, and as the interest in appearance and satisfaction on appearance of them got higher, the level of knowledge on aromatherapy of them was high. In common characteristics, as the living standard of them got higher, and pocket money of a month of them got more, the level of attitude on aromatherapy of them was high. As the interest in appearance of them got higher, the level of attitude on aromatherapy on the interest in appearance of them was high. In the characteristics related with the skin, as the skin health condition of students got healthier, the level of attitude on aromatherapy of them was high, and it was high in the students who had much agony on the skin color.

This study analyzes trade competitiveness by classifying the classification by item among Korea and the 10 ASEAN member countries into high level and medium-high level technology industry groups, medium level, medium-low level, and low-level technology industry groups. Before analyzing each of the 10 member states, I investigate the trade competitiveness between Korea and ASEAN, and analyze the trade competitiveness of Korea, especially among the 10 member countries, with Korea having a competitive industrial force. The study results revealed that trade with Vietnam was actively promoted, with Korea-Vietnam trade volume also growing far above that of other member states. And trade with Korea was brisk in the order of Singapore, Indonesia, Malaysia and the Philippines. The analysis of the trade structure of the 10 ASEAN member states, confirmed that imports were also being made while exporting items in the high- and medium-level technology industry groups. The possibility of entering the Korean market was quite high, given that Korea imported high- and medium- and high-tech industrial forces while exporting low-tech industrial forces.

In this paper, we propose an adaptive BTC algorithm using the characteristics of the error signals. The BTC algorithm has a avantage that it is low computational complexity, but a disadvantage that it produces the ragged edges in the reconstructed images for th esloping regions beause of coding the input with 2-level signals. Firstly, proposed methods classify the input into low, medium, and high activity blocks based on the variance of th einput. Using 1-level quantizer for low activity block, 2-level for medium, and 4-level for high, it is adaptive methods that reduce bit rates and the inherent quantization noises in the 2-level quantizer. Also, in case of processing high activity block, we propose a new quantization level allocation algorithm using the characteristics of the error signals between the original signals and the reconstructed signals used by 2-level quantizer, in oder that reduce bit rates superior to the conventional 4-level quantizer. Especially, considering the characteristics of input block, we reduce the bit rates without incurrng the visual noises.
