The term 'Grid' refers to systems and applications that integrate and manage resources and services distributed across multiple control domains. Resource sharing is, necessarily, highly controlled, with resource providers and consumers defining clearly and carefully just what is shared, who is allowed to share, and the conditions under which sharing occurs. In this paper, we design and implement a grid access control system, called PGAM. This system works on heterogeneous resources, can be applied to the additional service development and its service, provides template account management mechanism, and tries to ensure site autonomy. This system is implemented to increase portability and to be tit tll any kind of economic model.

The purpose of this study is to analyze the school autonomy policy based on the system thinking perspective using causal loop diagrams. School autonomy was the main educational policy concerning school domain during the last government and was the instrument for school-based management, but it was not implemented effectively in site. The school autonomy policy practically disappeared as an explicit policy agenda in the current government. This study displays causal loop diagrams about the policy's logic and contents of school autonomy, in terms of curriculum, human resource management, and a supportive system. The causal loop diagrams depicting the implementation of the school autonomy policy are suggested concerning excessive enforcement and the confirmative mechanism for policy implementation. The conclusion provides some research implications and future directions.

Grid accounting model is necessary to support the demand and supply of id resource. Most grid accounting systems currently in use intrude upon site autonomy by modifying local accounting systems or calculate the cost of grid service without regard to site price policy. In this paper we propose and design Grid accounting model based on site price policy. This model assures autonomy of sites participating in gird computing and be able to actively cope with diverse billing services. Also this proposed model enables to provide RUS to Grid entities by transforming basic accounting information into GGF-UR format and allows this entities to exchange resource usage information. In this paper, proposed Grid accounting model enables sites to have autonomy of them and is evaluated for business model to enforce elaborate charging policy, compared with other systems.

The purpose of this study was to examine the relationship between the autonomy of dental hygiene students after clinical practice and their satisfaction with the clinical practice in an effort to determine how to manage courses in need of practice and how to provide education and guidance on clinical practice. A survey was conducted on the students in a three-year college in Gyeonggi Province, and the data from 295 respondents were analyzed. The findings of the study were as follows: 1. As for autonomy, the subjects got a mean of 3.60 in respect for others, and 3.40 in respect for themselves. 2. In regard to satisfaction with clinical practice, they gave the highest score of 3.58 to the content of the clinical practice, and they gave the lowest score of 3.09 to practice hours. 3. They gave higher scores to autonomy of clinical practice when their awareness of dental hygienist at the time of college admission and after experiencing the clinical practice was better and when they were more satisfied with their major. 4. They gave the highest scores to satisfaction with the clinical practice when they voluntarily chose the department of dental hygiene in terms of motivation for major selection, when their awareness of dental hygiene at the time of college admission and after experiencing the clinical practice was better and when they were more satisfied with their major. 5. The students who gave higher scores to autonomy of the clinical practice were more satisfied with the practice.

Grid makes a virtual high-performance computing resource by connecting geographically distributed heterogeneous resources. Building access control system is an important factor In the grid environment In this paper, we design and implement a grid access control system based on Globus Toolkit, which is one of the popular grid middleware. Especially, to guarantee the site autonomy for resource provider, we use several environment configuration files. Moreover, we design and implement PGAM to produce more detail and diverse information to ease the development of value added services.

In order to evaluate KOrea Multi-Purpose SATellite (KOMPSAT) application products and develop the multi-sensor data application technologies, the Product Validation Site (PVS) will be designed and constructed by Korea Aerospace Research Institute (KARI). Also KARl has a plan for acquisition of multi-sensor data such as ENVISAT ASAR and Project for On Board Autonomy (PROBA) Compact High Resolution Imaging Spectrometer (CHRIS) data through international cooperation with European Space Agency (ESA). These data will be utilized with KOMPSAT-2 Multi-Spectral Camera (MSC) data. KARI and ESA have identified a mutual interest in creating synergy in the joint exploitation of Earth Observation data for science and applications both in Korea and Europe. This paper summarizes the status of joint experimental studies between KARI and ESA for further applications and presents some expected results from related activities.

Integrated heterogeneous database systems provide the unified interface for users and applications today in order to access the underlying diverse data sources located in different sites. The multiple heterogeneous data sources have the different and specialized data structures and transaction processing capabilities. Because of local autonomy, the local system does not have the capability of cooperation to control the global transaction. Hence designing the global transaction manager with supporting the global serializability is difficult task. To resolve the well-known indirect conflict, we define the global transaction model by using the characteristics of global integrity constraints. And then we propose the site-locking operation and its protocol to manage the global transaction. The correctness and analysis of our site-locking protocol is proved and performance gain over the related other methods is also estimated in this paper.

This study aimed to analyze health promotion villages from the perspective of therapeutic architecture, and to provide basic information for planning relevant health facilities. On the basis of a review of previous literature, the characteristics of therapeutic architecture were classified into eight categories: safety, comfort, sociality, autonomy, openness, diversity, privacy, and natural environment. Field study and observation were performed in four health promotion villages that conduct programs for lifestyle improvement, physical fitness, and treatment; these villages were also considered to have a healthy residential environment. The researcher and three assistants visited the facilities and checked utilization of space through interviews with the staff and guided tours. Basic information about the subject facilities, such as the purpose of establishment, was gathered from websites before visits. Two of the villages examined in this study had a traditional Korean wooden structure, while the other two were reinforced concrete and masonry block structures. All the facilities emphasized the use of environmentally friendly material and harmony with nature. Each site was divided into the following areas: office, residence, health/treatment, public/rest, and outdoor. The safety standards of the healing architecture were not completely satisfactory at all facilities. In particular, it was found that they lacked adequate universal design equipment. However, the healing characteristics of autonomy and diversity were strong. With regard to autonomy, the facilities allowed visitors to select indoor-outdoor moving lines and the use of front- and backyards constructed on slopes. In addition, they were equipped with many entries, staircases, void, terraces, and crossroads. The architecture was aesthetically designed using feng shui symbolism, and visitors found the scenes depicted in various spaces in the villages to be stimulating. Besides, the facilities were constructed using natural materials, had a natural indoor environment, and provided a sense of spaciousness and flexibility.
