Geological symbols are used for describing geological information. But it's not ease to represent them in commercial GIS s/w, because of their complexity and diversity. This study aims at developing the geological symbol mapping tool for representing geological symbol on user's geological information. Geological symbol mapping too is a web application which can handle SHP format and map geological symbols based on user's requests. It manages geological symbols and mapping codes and symbols are mapped within the geological boundary according to the corresponding non-spatial field that is a mapping code. The system has functions to upload a user's GIS file, and download the converted image file which is mapped geological patterns. The system displays converted images to be check mapping results. Because the symbols are simple bitmap files, user(system manager) can design and apply them rapidly without considering specific commercial S/W. Thus, it is expected that this system plays an important role to disseminate geological standards such as geological symbols. And the results of this study can be used for developing global geological symbols and applying them easily

Currently, most IP multicasting applications are implemented based on Any-Source Multicast (ASM) model that supports many to many multicast services. However, it is known that current ASM-based multicast architecture has several deployment problems such as address allocation, lack of access control, and inefficient handling of well-known multicast sources. Source-Specific Multicast (SSM) working group in IETF proposed SSM architecture to overcome the weaknesses of ASM architecture. The architecture of SSM is based on one to many multicast services. Also, in order to provide SSM service, Multicast Listener Discovery Version 2 (MLDv2) protocol should be supported. In this paper, we introduce the architecture of SSM protocol and multicast group management protocol. After that, we present the architecture and implementation of IPv6 SSM and MLDv2 protocols in Linux systems.

Purpose : What confirm a patient's set-up precisely is an important factor in stereotactic radiosurgery Especially, the tumor is moved by respiration in case of lung cancer. So it is difficult to confirm a exact location by L-gram or EPID. I will verify a exact patient's set-up about this sort of problem by verification system(exactrac 3.0) Materials and Methods : The patient that had lung cancer operated on stereotactic radiosurgery is composed of 6 people. The 5 patients use an ABC tool and 1 patient doesn't use it. I got such a patient's L-gram and EPID image by Body frame(elekta, sweden), compared Ant. image with Lat. one, and then confirmed a set-up. I fused DRR image of CT and X-ray image of Verification system(exactrac 3.0) 3 dimensional, analyzed the coordinate value(vertical, longitudinal, lateral), and then confirmed a difference of existing method. Results : In case of L-gram and EPID, we judge an exact of the patient's set-up subjectively, and on we could treat the patient with radiation. As a result of using Verification system(exactrac 3.0), coordinate value(vertical, longitudinal, lateral) of patient's set-up was comprised within 5mm. We could estimate a difference of the coordinate value visually and objectively. Consequently, Verification system(exactrac 3.0) was useful in judging an exact patient's set-up. Conclusion : In case of Verification system(exactrac 3.0), we can confirm an exact patient's set-up at any time whenever, However, there are several kinds of the demerit. First, it is a complex process of confirmation than the existing process. Second, thickness of CT scan slice is within 3mm. The last, X-ray image has to have shown itself clearly. If we solve this problem. stereotactic radiosurgery will be useful in treating patients why we can confirm an exact patient's positioning easily.

Purpose: Undertreatment of canter pain, especially due to the differences in the perception of pain between the patients and caregivers, is a well recognized problem. The purpose of this study were to determine if there exist differences in communication about pain intensity scores between patients and their family caregivers in Korea. Methods: A total of 127 patient-family caregiver dyads who have experienced canter pain participated in this study at a hospital in Seoul for six months. The data were obtained by fare to face interview with a structured questionnaire based on Brief Pain Inventory-Korean version and other previous researches. The clinical information for all patients was compiled by reviewing their medical records. Results: Patients' 'worst-pain for 24-hour' and 'right-now-pain' scores estimated by family caregivers were significantly higher than those by patient themselves. The degree of agreement between patients and family caregivers in the estimate of patients' 'worst-pain for 24-hour' intensity categories was 78.7% for 'severe pain', 40% for 'no pain', 27.5% for 'mild pain' and 22.9% for 'moderate pain'. In case of 'right-now-pain' intensity categories, the agreement was 50% for 'severe pain', 47.2% for mild pain, 46.3% for 'no pain', and 26.3% for 'moderate pain'. Conclusion: This study demonstrates that the degree of agreement between patients and family caregivers in the estimate of patients 'pain intensity categories was less than 50% except for 'severe pain'. The results indicate that Korean family caregivers tend to overestimate the canter pain intensity of their caring patients, especially, when a lancer patient has 'moderate' or 'mild pain'. Health Providers are advised to educate patient-family caregiver dyads to use a pain measurement scale to promote their agreement in pain Intensity stores. Further analyses and studies are needed to identify the factors and differences that influence their communication about pain intensity scores between patients and their family caregivers.
