Since users want to have services correctly in their own position and surrounding circumstance in ubiquitous computing environment, it is very important to search, compose basic services and provide suitable services according to various circumstances. However existing techniques have been studied on service discovery mainly and lack consideration for position or preference of users. Furthermore, on service composition, they lists basic services simply and do not propose concretely method of use service history data for service composition. Therefore we propose a framework for context-based service provisioning middleware system, called COSEP, and Ontology engine with data ming. This research discovers services by reacting dynamically to circumstance information such as time and position of user, composites services using Ontology engine with data ming and offers newly created optimal services to users.

In this study, the total polyphenol contents, antioxidant activities and anti-proliferation effects of HepG2 cell lines in organic slovent fractions obtained from the main methanolic extract of P. yezoensis were analyzed. The polyphenol content of the $CHCl_3$ fraction was $10.3{\mu}g/mg$, slightly less than $13.08{\mu}g/mg$ of the water fraction, but $ED_{50}$ estimated by measuring DPPH free radical scavenging activity exhibited the highest $16.96{\mu}g/ml$ in the $CHCl_3$ fraction. The proliferation effects of $CHCl_3$ and EtOAc fraction toward HepG2 cells inhibited in a dose-dependent manner, showed 90% inhibition when treated for 24 hr at $900{\mu}g/ml$ of $CHCl_3$ fraction. Meanwhile gene expression patterns in HepG2 cells treated $50{\mu}g/ml$ of $CHCl_3$ fraction were identified with microarray analysis. Concerning the efficacy of P. yezoensis, gene ontology analysis explored the genes associated with response to molecule of bacterial origin, vitamin D metabolic process, and response to nutrient. Thus IL6R, CYP1A1 were selected as significant genes based on expression patterns of HepG2 cells, and pathway analysis indicates that ARNT might be considered as a upstream regulator. Also, expression analysis of IL6R and CYP1A1, activity of upstream regulator ARNT in HepG2 cells was confirmed based on Western blotting analysis at the protein level after being treated with 50 and $100{\mu}g/ml$ of $CHCl_3$ fraction.

In this paper, we attempt to realize the diversity of human actions in a virtual world in terms of the basic actions. We utilize the comprehensive knowledge structure of ontology to organize the human actions into an action hierarchy, each action being the root action of its associated hierarchy of specialized actions. Each basic action is implemented by composing the primitive motions and each basic action in turn by reusing those basic actions. Our approach to the development of these actions is focused more on their diversity and brevity than on their visual realism. Based on this design we develop a method to grasp virtual humans' characteristics and reflect those characteristics on their respective action patterns. We also present a mechanism for the agents to adapt their motions to diverse qualitative changes in environment. We apply these methods to such basic actions as walk, run and throw to demonstrate their viability.

Neiging Medicine(內經醫學) based on Yin-Yang and Five elements was the main stream of Korea Traditional Medicine until the end of 19th century. And the establishment of Sasang Constitutional medicine. In this paper, author proved that the Yin-Yang of Sasang Constitutional Medicine was different from that of Neiging Medicine and that explained the Yin-Yang of Sasang Constitutional Medicine as our own medicine. After considering the philosophical and medical background of Sasang Constitutional Medicine, and author researched the Yin-Yang of ontology, structure, function, symptoms in Sasang Constitutional Medicine. Also we compared this with that of Neiging medicine. The results were as follows 1. Neiging Medicine was based on the Yin-Yang and Five elements centering on the nature and Sasang joy, and pleasure centering on the human. 2. The ontology of Sasang Constitutional Medicine were the mind as a unitary substance, the mind and body as a dual substance, and affair, mind, body, and objects as a four substance which were the basic theory of philosophy. 3. Sasang Constitutional Medicine explained social phenomenon with a four substancial structure consisted of affairs, mind, body, and objects, a complex four substancial structure consisted of heaves, human, nature and order, and a three dimension structure including time. 4. On the other hand Neiging Medicine recognized seven emotions as five emotions, Sasang Constitutional Medicine recognized seven emotions as qi, nature, and emotions which consisted of sorrow, anger, joy, and pleasure. The qi had an effect on internal and external part of body and the nature and the emotion had an effect on the upward and downward of body. 5. It was taked great importance to control the up and down balance and the internal and external balance in Sasang Constitutional Medicine instead of reinforcing and reducting method of Neiging Medicine. 6. The Yin-Yang of Korean Traditional Medicine developed centering on the human from centering on the nature and Sasang Constitutional Medicine was a practical medicine compared with Neiging Medicine.

To ensure access to rapidly growing video collection, video indexing is becoming more and more important. In this paper, video ontology system for retrieving a video data based on a scene unit is proposed. The proposed system creates a semantic scene as a basic unit of video retrieval, and limits a domain of retrieval through a subject of that scene. The content of semantic scene is defined using the relationship between object and event included in the key frame of shots. The semantic gap between the low level feature and the high level feature is solved through the scene ontology to ensure the semantic-based retrieval.

[Purpose] As Panax ginseng C. A. Meyer (ginseng) exhibits various physiological activities and is associated with exercise, we investigated the potential active components of ginseng and related target genes through network pharmacological analysis. Additionally, we analyzed the association between ginseng-related genes, such as the G-protein-coupled receptors (GPCRs), and improved exercise capacity. [Methods] Active compounds in ginseng and the related target genes were searched in the Traditional Chinese Medicine Database and Analysis Platform (TCMSP). Gene ontology functional analysis was performed to identify biological processes related to the collected genes, and a compound-target network was visualized using Cytoscape 3.7.2. [Results] A total of 21 ginseng active compounds were detected, and 110 targets regulated by 17 active substances were identified. We found that the active compound protein was involved in the biological process of adrenergic receptor activity in 80%, G-protein-coupled neurotransmitter in 10%, and leucocyte adhesion to arteries in 10%. Additionally, the biological response centered on adrenergic receptor activity showed a close relationship with G protein through the beta-1 adrenergic receptor gene reactivity. [Conclusion] According to bioavailability analysis, ginseng comprises 21 active compounds. Furthermore, we investigated the ginseng-stimulated gene activation using ontology analysis. GPCR, a gene upregulated by ginseng, is positively correlated to exercise. Therefore, if a study on this factor is conducted, it will provide useful basic data for improving exercise performance and health.

This paper proposes an algorithm to transform RDF(Resource Description Framework) models for ontology into CPN(Colored Petri Net) models. The algorithm transforms the semantics of the RDF model into the topology of the CPN by mapping the classes and the properties of the RDF onto the places of the CPN model then reflects the RDF statements on the CPN by representing the relationships between them as token transitions on the CPN. The basic idea of reflecting the RDF statements on the CPN is to generate a token, which is an ordered pair consisting of two tokens (one from the place mapped into the subject and the other one from the place mapped into the object) and transfer it to the place mapped into the predicate. We have actually built CPN models for given RDF models on the CNPTools and inferred and extracted answers to the RDF queries on the CPNTools.

From th Study on A Study on the Thesaurus of Korean medical information for developing search engine, the conclusion is as follow. Knowledge based information system consists of concepts, facts and relation. The final goal of developing the Knowledge based information system is to select, store and control the knowledge and information of Oriental Medicine. Considering limitation of organizing the knowledge system, it is difficult to realize complete basic system and application method. In order to work, it is necessary to combine experts in each part, for example Domain experts, Information and Knowledge engineer. Through the development of knowledge based information system, we can construct EMR(Electronic Medical Record) system in the near future, and it is possible to make semi-expert system. To make Knowledge based information system, we need to establish standards of information that make the distribution of Knowledge and information easily.

The stress is an unavoidable result and a complex phenomenon in modern society. too, Human activity changes under control of the stress. The stress is a reaction to adrenalin or other stress hormones. It provides the power for fighting and the energy for going away from dangers. Because of the stress, our bodies increase the pulse, the blood pressure and the breath for more blood and more oxygen. So, in this research, we are measuring those which was increased by the stress. Also we will examine the change of HRV and APG on music. After that, in order to reduce the stress, we will design matching system that is based on the sense for music by using Zigbee.
