This study proposes the actualization of a standard data model for activities through the development of clinical document architecture for medication administration using the health level 7 development frameworks(HDF) process based on object oriented analysis and development method of health level 7 V 3. Medication administration is the most common activity performed by clinical professionals at healthcare settings. A standardized information model and structured hospital information system are necessary to achieve evidence-based clinical activities. We had used HDF and various tools(Rose tree, RMIM designer, V3 generator) to create the clinical document architecture(CDA). This allowed us to illustrate each step of the HDF in the administration of medication. This study generated a information model of the medication administration process, which is one clinical activity. It should become a fundamental conceptual model for understanding international standard methodology by information technology(IT) developers with the objective of modeling healthcare information systems.

Buddhism that has arisen in India began to build the Stupa to enshrine body and Sari of Buddha as an object of worship. The stupa existed as a tome of holy leaders even before the birth of Buddha, which was called stupa or tupa in the Sanskrit and the Pali, the ancient language of India. The stupa was renamed accordingly in each Buddhism transmitted countries such as Ceylon, Tibet, Nepal, Myanmar, Thailand and China and also reshaped according to their own formative style. But its original meaning and type are kept unchanged. The stupa was established in the 4 holy places including the birth place of Buddha, the place where Buddha found enlightenment, the place where Buddha preached for the first time, and the place where Buddha died. Thus, a pagoda to commemorate holy ancient places is called Chaitya, which became differentiated from the stupa in which Sari is enshrined. The stupa means Nirvana, the eternal body of Buddha, and also a place filled with teaching and preaching of Buddhism. It signifies the symbol of Buddha who escaped from the death and rebirth, to achieve complete extinction, i.e. parinirvana, and to reach ultimate eternal world, rather than simply means death. During the non-statue of th Buddha period, people built the stupa to embody Nirvana of the Buddha, and worshipped the tomb where body of holy saints was enshrined. On the other hand, they also sanctified memorial things such as tools that holy saints used, the Bo tree under which one achieved Nirvana, Dharma cakra that implied words, footprint that carried out mission work, and a way to reach to heaven.

Contort-aware computing technology is one of the key technology of ubiquitous computing in the mobile device environment. Context recognition computing enables computer applications that automatically respond to user's everyday activity to be realized. In this paper, We use accelerometer could sense activity states of the object and apply to mobile devices. This method for estimating human motion states utilizes various statistics of accelerometer data, such as mean, standard variation, and skewness, as features for classification, and is expected to be more effective than other existing methods that rely on only a few simple statistics. Classification algorithm uses simple decision tree instead of existing neural network by considering mobile devices with limited resources. A series of experiments for testing the effectiveness of the our context detection system for mobile applications and ubiquitous computing has been performed, and its result is presented.

Compiler and language implementation courses have long been recognized as an important subject in Computer Science curricula. It is because not only the knowledge for a compiler plays important roles in understanding programming languages and systems but compiler technologies can be used in many applications. However it requires much effort to teach effectively it due to limited resources and time restriction. We present a compiler teaching model using Edu-IDEC which is a development environment of educational compilers. Edu-IDEC is a tool on the robot platform. It uses the Eclipse plug-ins and has functions like compiler developing tools, a reference compiler, visualization tool of syntax tree, visualization tool of object language, NXT robot controllers, and its simulator. We also present the evaluation results for our model by applying it to an actual class.

Recently, a MMORPG(Massively Multi-play Online Role Playing Game) has built distribute server by Seamless world. This paper proposes an efficient collision detection method. DLS is used to dynamically adjust spatial subdivisions in each the boundary regions of distribute server We use an index table to effectively utilize the relationships between in the nodes and can perform the collision detection efficiently by reconstructing nodes of the tree. Also, we maintain the information for the boundary region to efficiently detect the collections and adjust the boundary regions between distributed servers by using DLS. As the DLS uses pointers, the information for each server is not needed and the boundary regions between the distributed servers are efficiently searched. Using node index points, the construction table can be made to find between ray and neighborhood node, In addition, processes for Network traffic reduce because a copy of the boundary regions is not needed when a object moves with realtime.

The object of this series of experiments was aimed for the systematic and long-term radioactivity monitoring through indirect search of C-14 concentration level changes in the natural conditions around the operating nuclear facilities. The result of environmental radioactivity level through tree-ring analysis is increased after operating nuclear facilities and such a level can be proved to relate power generation closely. The measured result of ${\delta}^{13}C$ through the treatment of cellulose can be showed the level -30‰. This figure is very different from one which is measured the -17‰ of air sample by passive air sampling and -8‰ of air sample by active air sampling. And these differences can be assumed as isotope fractionation by photosynthesis, but the problem is more study as needed.

This paper presents the Web service generation system using virtual environments and databases. Main features include that the environments and databases are generated and maintained correspondingly. It means that the virtual environments are changed automatically if the databases are updated, and also that the databases are maintained accordingly as the information about the environments are modified at the scene End users can modify the property of the virtual environments in the scene directly using the VRML edit interface, which visualizes the structures of virtual environments. Each object can be accessed through the VRML editor, its property be modified directly, and the information is updated in the database automatically. Web service pages are maintained accordingly. In addition, we define a texture mapping method based on weighted view interpolation using 2 photo images for a scene. A texture mapping interface Is also provided for end users to generate realistic images themselves.

Refactoring is a kind of software modification process that improves system qualities internally but maintains system functions externally. What should be improved on the existing source codes should take precedence over the others in such a modification process using this refactoring. Martin Fowler and Kent Beck proposed a method that identifies code smells for this purpose. Also, some studies on determining what refactoring will be applied to which targets through detecting code smells in codes were presented. However, these studies have a lot of disadvantages that show a lack of precise description for such code smells and detect limited code smells only. In addition, these studies showed other disadvantages that generate ambiguity in behavior preservation due to the fact that a description method of pre-conditions for the behavior preservation is included in a refactoring process or unformalized. Thus, our study represents a precise specification of code smells using OCL and proposes a framework that performs a refactoring process through the automatic detection of code smells using an OCL interpreter. Furthermore, we perform the automatic detection in which the code smells are be specified by using OCL to the java program and verify its applicability and effectivity through applying a refactoring process.

In this paper, we propose the delivery problem on trees and two algorithms for the problem. The delivery problem on trees is that of minimizing the object delivery time from one node to another node using n various speed robots. Our first algorithm generates an optimal solution with some restrictions in handover places. In this algorithm, we assume that the handover can be made at a vertex of given tree. We try to find the handover places and the robots participate in handover from the start node to the destination node. The second algorithm extends the first one to remove the restriction about the handover places. The second algorithm still generates an optimal solution. The time complexities of both algorithms are $O((n+m)^2)$ where n is the number of robots and m is the number of nodes.

Till now, Korean spelling proofreading system has corrected words of a sentence from the relationship of a collocation or the grammatical information of the sentence. In this paper, we propose a system that corrects a word using the relationship among the sememes in a single sentence and substitutes an apt word for a word of the sentence that has the meaningful mistake by a mistyping. The proposed system makes several sentences that are able to communicate with each sememe. The substantives forms meaning tree according to the meaning of the word and the predicate of a sentence defines the meaningful relationship between a substantives of the subject and the object. After this system compares and analyzes the relationship of meaning, it corrects the mistyping of a word in a single sentence that includes an error. If the system finds out the semantic error by the mistyping, it applies the spelling proofreading method that proposed in this paper.
